And today, we're discussing how diabetes treatment has changed over the last decade. We're talking about patient selection criteria for starting them on CGM or an insulin pump and recommendations to primary care physicians about using diabetes technology in their primary care practices.
Joining me is Dr. Henry Zelada. He's an Assistant Professor of Medicine and an endocrinologist specializing in diabetes, metabolic and hormonal imbalances at UAB Medicine. Dr. Zelada, it's a pleasure to have you join us today. So tell us a little bit about the trends that you've been seeing in diabetes and how treatment has changed over the last decade.
Dr Henry Zelada: Thank you very much for having me today. The treatment of diabetes has changed in a positive way over the last decade. There are new insulin and also non-insulin medications now to choose, depending on our patient's needs. The use of GLP-1 agonists on SGLT2 inhibitors for sure have changed the approach of the diabetes management as they are now considered the second line of therapy after metformin in patients who have or those who are at risk to develop atherosclerotic cardiovascular disease.
In addition to that, the use of CGMs, continuous glucose monitoring, insulin bands, and also the use of more advanced technologies such as integrated hybrid closed loop systems are options now available for our patients.
Melanie: Well, it's certainly an exciting time in your field. And as an exercise physiologist myself, I've been seeing all of these things develop. So we're going to talk about CGM and insulin pumps. But before we do, Dr. Zelada, how much do healthcare providers rely on patient-provided data when it comes to managing diabetes? I'd like you to speak about some of the barriers to the use of self-monitored blood glucose and, you know, lack of timely, regular feedback, whatever you'd like to say and what you've been seeing as far as the technology that is available to patients today.
Dr Henry Zelada: Absolutely. The technology is there on the market. Unfortunately, not every patient qualifies to get CGMs. In the past, there was a misconception that CGMs were mainly used for patients with type 1 diabetes. However, there is research upcoming that suggest that CGMs are also indicated for patients with type 2 diabetes and the results are promising.
I do believe that the conversation about starting a CGM should be initiated in the primary care setting. Of course, we're always happy to receive any kind of referral and every referrals are the best. But starting a conversation about the benefits of CGMs from the primary care setting, it's for sure a class for the patient.
Melanie: Well, then speak about patient selection just a bit. For other providers, what patients do you consider starting on CGM?
Dr Henry Zelada: Yeah. That's a great question. So just to understand a little better what CGM is, CGM in simple words are glucose sensors. They measure the glucose from the interstitial fluid every one to five minutes, depending on the type of CGM. So a CGM has three parts, a sensor that measures the interstitial glucose levels, a transmitter that transmits the information from the sensor to a receiver and the receiver, which is a device that receives the glucose data from the transmitter for viewing interpretation. Most lately, patients use their phones as a reader.
In regards of what patients should we consider to start a CGM, I believe that's a great question and a very common question that is around. So there is a common misconception to think that CGMs are only indicated for patients with type 1 diabetes as I just said. There is a recent randomized clinical trial. The name of this trial is called the MOBILE study. This trial is interesting because it was done in primary care settings in 15 hospitals in the United States on patients with type 2 diabetes who were on just basal insulin and oral antidiabetic medications.
They compare two groups of these patients, patient who checked his sugars using glucometers, two patients who use CGMs. The aim of this study was to see if there were any changes in their A1c after eight months. The group that used CGMs had an A1c drop by 0.4% compared to the group that use glucometers. So this study along with others have suggested that patients who use CGMs become more conscious about their diabetes and what they eat when they are using a CGM. For example, if a patient is about to eat and his or her sugars are in the 300s, they will be more cautious what to eat. And that's something that has been shown and this is evidence-based how CGM by itself controls an A1c by 0.4% to 0.5% just by wearing it. So I do believe that CGM should be offered to any patients with diabetes who takes at least one shot of insulin per day.
Melanie: That's so interesting, Dr. Zelada. I didn't know that. So thank you for sharing how that really responds and gets the patient to realize what's going on with their glucose. So when do you consider starting an insulin pump?
Dr Henry Zelada: It's interesting to see many patients who come to our diabetes clinic with uncontrolled diabetes and thinks that an insulin pump is what's going to solve their problems. And that's a misconception in general population. We use mainly insulin pumps in patients with type 1 diabetes. And the reason is because these patients require small changes in their insulin doses that are only possible to be made using an insulin pump. That's one indication.
The other possible consideration is when we want to start using something that is called hybrid closed loop system. A hybrid closed loop system is a system that comes with three parts, a CGM, a glucose sensor; then an insulin pump, and also a computer program called algorithm that takes data from the pump and CGM and adjust the pump's insulin delivery automatically. Today, we have two hybrid closed loop system. One is called Control-IQ and the other is the hybrid closed loop system from the Medtronic pump.
However, it's also important to remember and consider that some patients with type 2 diabetes could also be candidates for insulin pumps. There is new evidence that suggest that Omnipod insulin pump, that's another type of pump, could be considered on these patients. So the decision should be made with a patient, their needs and their expectations.
Melanie: Well, it certainly is an interesting discussion to have between patient and provider. And as lifestyle management remains very basic to long-term diabetes management and control, and there's no one-size-really-fits-all, Dr. Zelada, what are the latest recommendations on diabetes lifestyle management? Anything you'd like to add to this discussion?
Dr Henry Zelada: Yeah, absolutely. Lifestyle management helps a lot to control diabetes along with exercises and a good diabetic plan for the patients. And again, the treatment should be individualized. Every single patient with diabetes have different goals and actually have different needs. So the endocrinologist or primary care should identify what's the goal in order to choose the right medications for the patients.
Melanie: Well, there are so many options available today. And you discussed medications earlier in the podcast. As we wrap up, what do you recommend to primary care physicians about using diabetes technology in their primary care practices? And what you'd like to take-away message to be on this podcast today?
Dr Henry Zelada: I do believe that starting a conversation with their patients about using CGMs in the primary care clinics should be considered. I do not expect that a hybrid closed loop system is initiated in a primary care setting. But starting a CGM, a glucose sensor, should be considered, because of all the benefits that we have just discussed.
Also an early referrals is also very well appreciated by us when the diabetes remains under control and also when they suspect atypical forms of diabetes. We need to understand that diabetes is more complicated than type 1 versus type 2. There is a full spectrum of atypical forms of diabetes that needs to be identified and needs to be addressed properly. So I do believe that primary care physicians who suspect atypical forms of diabetes should refer their patients to the diabetes clinic.
Melanie: Great information, Dr. Zelada. Thank you so much for joining us today.

There is no commercial support for this activity. - TranscriptionMelanie Cole (Host): . Welcome to UAB Med Cast. I'm Melanie Cole and I invite you to listen as we examine the complexity of skull-based surgery from the anterior perspective and the importance of a team approach. This is part two of our two-part series. Joining me is Dr. Kristen Riley. She's a Professor of Brain and Tumor Neurosurgery and Neurosurgical Oncology at UAB Medicine and Dr. Brad Woodworth. He's the James J. Hix Professor of Otolaryngology and Skull-Based Surgery at UAB Medicine. Doctors, I'm so glad to have you join us today. This is a fascinating series here.
So, Dr. Woodworth, I'd like to start with you. Will you explain a little bit about skull-based tumors and the disease processes that you treat?
Brad Woodworth, MD (Guest): Yes. Thank you. Tumors of the anterior skull-base can occur anywhere throughout the ventral skull base. And that includes up in the frontal sinus, which is behind the forehead. And then all the way down to what's called the clivus. And so, that's the general area of the skull base that we're talking about when we talk about anterior skull-based surgery. The most common areas of course are going to be the pituitary type tumors that you're going to get in the sella area, in the central anterior skull-base, but you can also numerous types of tumors that we treat in the ENT world that are attached near the olfactory area where the smell nerves come out of the skull base as well as the ethmoid roof, which is between the eyes.
There's a number of different benign and malignant type pathologies. The most common things that we see from an ENT perspective are things like inverted papillomas, but these also can turn into things called squamous cell carcinomas, which is a malignancy. And the tumors are attached at the skull base. That's where we really joined forces as a multidisciplinary approach to attack these tumors. So, the most common malignant tumors that we see in this area are squamous cell carcinomas, as I mentioned, but also things like malignant melanoma, esthesioneuroblastoma, which is a smell nerve type tumor. And so these tend to be, they tend to go above the skull base and they can actually enter into the dura, which is the covering of the brain. And so this is where that two team approach is really critical to adequately address these tumors.
Kristen Riley, MD (Guest): And I'll add to that and I'm sure we'll get into it. Brad said, it's critical that we have both ENT and neurosurgery and that we work collaboratively from the time the patient is diagnosed. So, we can come up with a surgical plan that's best for the patient. And often is something that we can do entirely endoscopically endonasally, versus 15 years ago, these tumors would be approached with maybe even an open approach through the nose, but absolutely they were most often approached with a bicoronal craniotomy. And so it's fantastic that we can avoid that for many of our patients.
Host: Well, thank you both. So, Dr. Riley, what's different about the lateral and anterior skull-based tumors in terms of difficulty in treatment or challenges that you see and the differences of each?
Dr. Riley: So, when we talk about lateral skull base we often are in the retromastoid area, area of lower cranial nerves. The anterior skull base is a more cephalad and ventral location. Certainly with involvement of cranial nerves, but typically the higher cranial nerves, one through six, whereas the lateral skull base is more six through 12. As these are different locations, the surgeons that operate in these areas are specialized in different ways. So Dr. Walsh, whom you spoke with earlier from ENT is specialized in surgery related to the area of the lower cranial nerves, retromastoid area.
Sort of the law, again, the lateral skull base, whereas Dr. Woodwork's area of expertise is more of the anterior skull base, the endonasal approach. And so these areas are, they're geographically a little bit different. The cranial nerves and blood vessels that are in these areas are different and hence the need for and importance to have a specialized approach with surgeons who, who operate in those areas very commonly.
Dr. Woodworth: I would like to add that also one of the the key issues with doing anterior skull-based approaches are the large holes that are made and the difficulty with repair. And so that's where the technical aspects of our field have really gained traction in the last 15 years is doing good multi-layer type repairs and reconstructions to the skull-base to prevent a postoperative spinal fluid leak.
Host: Well, thank you for that. And along those lines, then Dr. Woodworth, and before we get into some of the really exciting techniques and advances that are in your fields, please tell us about this multidisciplinary approach and given the complexity of many skull-based disorders and with increasingly complex treatment algorithms; who is in charge of patient care? Tell us a little bit about how you all work together.
Dr. Woodworth: Sure. I think we take a co-equal approach to the patients. Say for example, someone with a very large habitus, who's got a spontaneous cerebral spinal fluid leak, for example, and a large anterior cranial fossa encephalocele. So that's going to be a patient who's got idiopathic intracranial hypertension. And so in those cases Dr. Riley and I will perform a lumbar drain at the beginning of a case to assess intracranial hypertension, assist with the cosurgeon in the case at the time of the surgery. But then really afterwards, we're monitoring the intercranial pressure and Dr. Riley really is responsible in that aspect too, if the patient needs a ventricular peritoneal shunt, for example although we only do this about 10 to 15% of the time. It's a very valuable intervention when we identify those patients that require it for a significantly high pressure that are more likely to releak in the future.
When it comes to tumors, you know, we present our cases at a multidisciplinary tumor board. So, radiation oncology and medical oncology are involved as well as other surgical oncologists, neurosurgeons, ENTs and in that scenario where we're formulating a treatment plan for patients with large skull based tumors. And so if you have a cancer that's transdural and we think that chemotherapy might be appropriate first, then they'll get chemotherapy. And then we might re image and determine whether they need an operation or consolidation, chemo, radiation, or even surgery after radiation. And so all those decisions are made on a team like basis. From a standpoint of the collaboration of removing these tumors, that the neat techniques that we have in the last 10 to 15 years is the ability to use scopes through the nose, prevent open incisions, but even in cases where you have tumors that go out to the facial skin, for example, we'll still have my head neck colleagues, for example, may do a maxillectomy at the same time. But then removing the skull base with Dr. Riley. And so even those situations may have other ENTS with different sub-specialties involved. So again, really emphasizing that team approach. Now the endoscopic approach is something very specific to Dr. Riley and myself. I use scopes to approach the tumor and basically skeletonize around the base of the tumor on the skull base.
And then Dr. Riley will come in and in a collaborative fashion, I'll use endoscopes and suctions and she'll use endoscopic scissors and and different grasping tools to remove the skull base through the nose. And we actually can make and repair very large defects here. Recently, you know, four to five centimeters sometimes in these multilayer techniques. We use different types of grafts in the intradural space, but we can also use nasal septal flaps, which is a really useful tool to provide vascularized tissue to repair the skull base.
Other options include endoscopic use of paracranial flaps, which are traditionally used in an open fashion and we've, we use those sometimes when we don't have a nasal septal flap option and we have very large defects. So, I think there's a lot of really nice specialized tools that we have at our disposal that really prevents a lot of postoperative CSF leak and complications that we see.
Kristen Riley, MD (Guest): And just to add in response to the question about how the patients kind of come through our process. So, the nice thing is that we work so closely together. Our clinics and our operating days are coordinated such that if a patient is referred for example, for a pituitary tumor, I have a clinic with an endocrinologist where I see many patients with the pituitary tumors. The majority of those patients that require surgery do not require advanced skull-based closure techniques such as nasal septal flaps, but there is a certain proportion of patients that do. And when that case arises, I coordinate the evaluation with Dr. Woodworth, typically on the same day that I see the patient and and that way the patient does not have to make separate appointments. The referring physicians do not need to make separate appointments. Likewise, when Dr. Woodworth is referred a patient with a skull based encephalocele that needs an evaluation for intracranial hypertension, as he mentioned, that involves placement of a lumbar drain and postoperative evaluation of pressures.
Typically the patient will come in, be referred often by an outside ENT to Dr. Woodward's clinic, he'll coordinate for the patient to see me on the same day. So, I can counsel the patient about the lumbar drain and about the possible need for a shunt. And then our surgical treatment again is coordinated in an efficient manner where typically the patient has the operation with the lumbar drain and repair of encephalocele and then 48 hours later, if their pressures are in a range that they require a shunt, I perform the shunt surgery at the same hospitalization. Again, all in a very coordinated and efficient manner. Our goal is to get the patients into the system and take care of them in this group effort, but not to have outside referring physicians need to make multiple referrals. They get to the door and we'll take them through the process.
Host: Well, I'm so glad that you mentioned outside referrals. So, Dr. Riley, when is it important to refer? What would you like referring physicians to know about communication? And then you can also go into any improved radiologic imaging, anything exciting, anything you want to talk about in your field?
Dr. Riley: So, I would say that, you know, for skull-based tumors, I think that these tumors are often best approached in a multidisciplinary team effort, like we've talked about here on this podcast and really a referral center such as UAB and an academic center is the best place for that to happen. And so any malignancy of the skull base, we would encourage referral here. Benign tumors, such as pituitary tumors, studies have shown that outcomes are best when tumors like pituitary tumors are taken care of at a high volume center and the private practice world while there are many excellent neurosurgeons, if they don't have a referral practice and a multidisciplinary pituitary clinic, they're not going to have access to the same resources that we do here. So, always encourage any pituitary tumor patient to be referred. And as we have alluded to skull-based encephaloceles that require a complex operative approach in order to prevent recurrent encephaloceles in the future, we would always encourage referrals of those and finally tumors that are assumed would require a combined skull-based and craniotomy approach, especially if an outside surgeon has suggested, that's the only way to approach those tumors.
Very often we find that we can approach them endonasally with a much more minimally invasive approach, that's certainly preferable to the patient without compromising anything in the quality of care. So, those are the conditions we would recommend referral. In regards to imaging, we are certainly quite excited about our new intra-operative MRI, which will be coming online in the next month or two.
It's an MRI suite that is within the operating room. So, during a procedure, we can obtain MRI imaging to evaluate extent of resection, if there's anything that we have a question about. That certainly is something that's exciting for us here at UAB. It's not going to be applicable to all anterior cranial endoscopic cases, but certainly there are some that it may provide a significant benefit for.
Host: What an exciting time to be in your field. So, I'd like to give you each a chance for a final thought. So, Dr. Woodworth, tell us a little bit about aftercare, the team approach, as far as after the surgery, where you are involved, where your colleagues are involved and what you would like the listeners to know.
Dr. Woodworth: Yeah, so that's a really important point. So, the care of the skull-based patient is really important from a postoperative standpoint, because the nose and sinuses are really prone to developing sinus infections, obstructive sinusitis when there's operations that create a lot of tissue destruction.
And so, what we find is you know, I see the patients multiple times postoperatively, where we remove packing that's either supporting a skull-based repair or keeping sinuses under good condition or open and patent. Then we initiate numerous types of medical therapies, like, sinus rinses or nasal rinses to improve the overall nasal health of the sinuses afterwards.
These patients, especially post radiation, can get a lot of what's called post radiation crusting. And so the aftercare for any sort of treatment modality is really important to help with overall sinonasal quality of life of these individuals.
Host: And Dr. Riley, last word to you. What does current research indicate for future developments? Are you doing any research that other physicians may not know about, things you're doing at UAB? Kind of wrap it up for us.
Dr. Riley: Sure. So, I think one of the most exciting areas of research is looking for targeted therapies for tumors, looking at molecular markers in tumors that are specific to patients, in individual patients that can help guide their adjuvent care. And UAB is certainly on the cutting edge of that. I think that's quite exciting. We also have a research project looking at familial pituitary tumors. And so that's an exciting area. So, we are thrilled that our patients benefit not only from the expertise from a technical standpoint, from our team approach, from the coordinated care, but also to be part of research and have opportunities for clinical trials and other new advancements in the field.
Host: Thank you both so much. What a fascinating episode this was on the complexity of skull-based surgery from the anterior perspective. Listeners, this was part two of our two part series and a physician can refer a patient to UAB Medicine by calling the mist line at 1-800- UAB-MIST, or you can visit the website at UABmedicine.org/physician.

I'm Melanie Cole and today, we're talking about genetic counseling, the benefits for cancer treatment. Joining me is Claire McDonald. She's a Genetic Counselor in Cancer Genetics at UAB Medicine. Claire, it's a pleasure to have you with us and what an interesting topic we're discussing today. And you know, we've heard about BRCA testing and providers are referring their patients for this. But tell us about some of the other types and the main types of genetic testing in oncology. And I'd like you to tell us about somatic tumor testing for treatment versus germline testing for hereditary cancer risk.
Claire McDonald, MS, MPH, CGC (Guest): Right. So, there are really two main types of genetic testing in oncology. The two you just listed. There is somatic or tumor testing, and then there's germline testing. So, somatic testing looks for gene changes in a sample of the tumor itself. And by definition, all cancers have gene changes that are not found in the rest of the body. Those changes have happened by chance as the DNA replicates. And they're what allow the tumor to actually grow uncontrolled and to be a cancer. So, the somatic testing can have treatment implications because there are plenty of drugs that are known to be effective only if certain gene changes are found within that tumor.
And somatic testing is continuing to become more important over time for cancer treatment, as research about targeted therapy progresses. And then separately there's germline testing, which is done on blood or saliva and can look for inherited gene changes that we'd expect to find in all cells of the body. So, if someone has a gene mutation identified on germline, think that indicates an increased risk of cancer. And each gene has specific cancer types that are more prevalent for people with a mutation in that given gene, whether it's BRCA or a different gene that's been identified. And then there are medical management recommendations such as increased cancer screening or preventative surgeries that can be used for patients who are found to have one of those germline mutations.
Host: So interesting and how somatic tumor is really helping to pave the way for various treatment options. Right? So, tell us a little bit about a genetic counselor's role in oncology and the benefits of seeing a cancer genetic counselor for other providers, Claire. They're telling this to their patients, tell them what you want them to be telling their patients.
Claire: Yeah, absolutely. I think a lot of times patients are told they're being sent for genetic testing and that is some of what we do, but it goes beyond that as well. So, genetic counselors take a detailed, personal and family history in the context of cancer. We focus on cancer and we assess familial cancer risks. And we determine whether genetic testing is appropriate for the patient and which tests should be ordered. But like I said, we also do more than that. One important part of our job is discussing the risks and benefits of testing with the patient and helping them decide whether they want this information, whether it could be beneficial for them because not all patients will want the information that genetic testing can provide.
And we actually have training in counseling in addition to the science of genetics and facilitation of that decision making is definitely a benefit of seeing a genetic counselor. We also assist their healthcare teams in developing medical management plans if a genetic diagnosis is made. So, if someone is found to have an increased risk for cancer, based on a genetic test result, plans can be made for screening that help detect cancer early, when it's easier to treat, or in some cases there are medications or surgeries that can reduce the risk of cancer.
We can also make recommendations or refer to other specialists based on family history, if the patient tests negative or chooses not to have the genetic testing. So, we offer, some insight beyond just what a positive genetic test could show. So, for instance, females with a family history of breast cancer may consider having an evaluation at a high risk breast clinic to see whether they qualify for increased breast screening.
An example could be having MRIs every year, in addition to mammograms, to try to increase detection of breast cancers. And then another example of that is individuals have a first degree relative with colorectal cancer should have colonoscopies every five years starting at age 40, or maybe even younger, depending on the youngest age of diagnosis in their family. And that's different from recommendations for colon cancer screening in the general population. So, since only five to 10% of cancers are hereditary, where we find one of those germline mutations, these recommendations based on family history are important for a lot of our patients.
Host: Well, one of the things I find most interesting when you said that you're also trained in counseling, because I think for providers, that's one of the big questions they get, they meet with you, they get their test results, then what, then they get the inevitable questions. What to do with this information. Speak about some of the practical aspects of the genetic test and how you counsel your patients on whether they go and work in their medical home. Do they work with you? How does that whole referral process work once they get the information and they're trying to figure out what to do next?
Claire: So, a lot of times I'll make direct referrals. So I'll send a message to the Prevention Clinic here at UAB, which is a high risk breast clinic. And they will contact the patient and set up an appointment. And then that patient gets to see one of the nurse practitioners over there and get that personalized evaluation. Or I can refer them to a GI doctor that I know is familiar with family history of colon cancer. So, they can start talking about getting their colonoscopies, things like that.
Host: Now, some people think that it's easier to do these direct to consumer testing, like 23andMe, if they're concerned about hereditary cancer risk and maybe the whole family does it, what do you think of those?
Claire: So, I think it's a complicated topic, but the short answer is that it depends on the company. Some companies like 23andMe test for very limited health information. For instance, you mentioned BRCA, many people have heard of the BRCA or BRCA one and two genes. There are thousands of different mutations or misspellings in those genes that can cause the gene not to work properly, which is what leads to that increased risk of cancer. And 23andMe's tests only actually looks for three of those variants and they're founder mutations in the Ashkenazi Jewish population. So, this means that a negative result for someone who does that test, doesn't actually rule out a mutation in one of those genes, because it's not a fully comprehensive test.
And so it will be more useful for individuals with Ashkenazi Jewish ancestry than those who don't have that ancestry, but any person can still have other mutations in those genes or in the many other genes that are not included on that test. And then in addition, if someone does get a positive result in a BRCA gene on 23andMe, medical grade testing is also recommended to confirm that positive test result. So, they would still need to get another genetic test to make sure that's accurate. Then there are some other companies that offer what I'd refer to as consumer initiated medical grade testing, and those include Color Invitae and JScreen, and they do offer more comprehensive genetic testing.
These companies require approval from an ordering provider, such as the patient's primary care doctor, or they also have third-party doctors, that partner with the company and they usually offer a call with a genetic counselor who's employed by that company to discuss the results as well. So, that's a little more comprehensive than something like 23andMe, and does allow access to a genetic counselor.
But my biggest recommendation would just be for any patient who's concerned about hereditary cancer risk to have a discussion with their primary care doctor or a genetic counselor or other healthcare provider before ordering one of those tests or deciding what might be the best route for them.
Host: One of the things that I think keeps people from wanting to do this and myself included are the insurance implications of hereditary cancer testing. Tell us a little bit about possible insurance discrimination concerns and how you counsel your patients with these concerns, especially if they have a positive reason.
Claire: If someone tests positive for a gene mutation, there's a law called GINA that protects against discrimination from large employers and health insurance. So, this means that for someone who tests positive, their health insurance company can't raise their premiums or deny coverage based on genetic testing results.
But GINA does not apply to other types of insurance, such as life, long-term care or disability insurance. And for those types of insurance, companies can legally ask whether a person has had genetic testing and can raise premiums or deny coverage based on their response. And also other factors such as personal and family history of cancer or other health conditions.
So, even sometimes if a person has a strong family history, they haven't had a genetic test that still might impact those things. But some patients like to establish these plans before having genetic testing, if that person tests positive, but they already have a plan in place, the company can't change that plan retroactively, and they're not required to call and send and update.
And so when I'm counseling patients, I think this is an especially important consideration for those who've never had cancer where testing positive might really impact the way these insurance companies think about their risk. And also for those who know that there's a gene mutation in their family and therefore they have a higher chance of testing positive than some of those other patients. So, particularly for patients in those situations, I make sure to let them know about GINA, what it applies to, what it doesn't apply to. And then sometimes they'll elect to go, put those plans in place before proceeding with tests.
Host: It's complex. It's an interesting aspect of this amazing field of genetic counseling. As we wrap up Claire, how is the field of cancer genetics, and genetic counseling evolving? And what would you like to see, or where do you see it going in the future? Please offer your best advice, referral information, any other final thoughts that you have.
Claire: So, the field is evolving constantly. One thing that comes right to my mind is that the cost of testing has greatly decreased in the past 10 years. So, some labs will actually offer a $250 self-pay price. So, whether either insurance won't cover the test or there's a high out of pocket cost due to something like a high deductible plan, patients can forgo their insurance and just pay $250 out of pocket for the test. And a test this cheap, really would have been unheard of in the recent past. So, I sometimes see patients who come for updated testing because there are a lot more genes to look at since the last time they had testing. And they have stories about paying thousands of dollars for themselves or other family members to have testing in the past.
So, while $250 is still a lot of money, many patients are reassured to hear that there's financial assistance. And even without financial assistance, there's no chance they'll end up paying thousands of dollars out of pocket, $250 is really the worst case scenario. There are also other new genes being discovered and described.
So, 10 years ago, a patient with early onset breast cancer would have only had BRCA or BRCA one and two testing. Whereas today I offer a 23 gene panel for that person. There's also a new type of testing called polygenic risk score. That's being done mostly on a research basis. We often see what we call familial cancers, which describes families with more cancers than we would expect by chance, but we can't find any gene mutation in that family. These families likely have an increased risk of cancer due to a combination of genetic and environmental factors that are shared within families. But we can't really pinpoint anything specific for them right now, because there's not a change in a single gene that we can identify. A pologenic risk score looks at hundreds of genes where each individual variant may increase or decrease the risk of small amount. And the variants themselves likely don't have a significant impact on cancer risk individually, but they may have an added effect when they're combined or added up together. So, the question is how to interpret these results and translate them into action, such as what would we recommend for increased screening for certain cancers?
We're not quite there yet, but if the interpretation improves in the research setting, I'm hopeful, this type of testing or other updates in technology may shed some light on the apparent increased risk in some families who have negative genetic testing today. And 20 to 30% of cancers are familial as opposed to the five to 10% that are hereditary. So, useful updates in technology has the potential to provide answers for many patients.
Finally, one last thing, I think genetic counselors have really been at the forefront of Telemedicine, particularly in cancer because a physical exam is not usually part of a cancer genetics evaluation. We have more flexibility to be able to talk with patients over the phone or on video chat. And this has been useful, not only during the current pandemic, but also before then, and will continue to be helpful for expanding access to our services for patients who live several hours away from the nearest cancer genetics clinic, because there aren't a lot of cancer genetic counselors. And so being able to offer that flexibility is one way to expand our services.
Host: What an interesting topic and a fascinating field that you're in Claire. Thank you so much for joining us today and really giving us a nice update on cancer genetics in oncology.

He's a Clinical Professor of Neurosurgery at the Greystone Neuroscience Center Office of UAB Medicine, and one of the few neurological specialists in the country, who's board certified in both neurosurgery and neurology. Today, we're giving an update on spinal stenosis, helping patients receive faster treatment.
Dr. Staner can help with this, by seeing patients in the clinic at Greystone and directing them to the appropriate care. Dr. Staner it's a pleasure to have you join us again today. Tell us a little bit about some of the changes in spinal stenosis and give us some recent updates on the impact on the quality of life for patients.
Thomas Staner, Jr. (Guest): Well spinal stenosis is a topic that is becoming more relevant because of our aging population. Stenosis, you know, Greek word is to narrow is kind of comparable to having wires in a big pipe in a normal person or wires and a straw in a person who has some compression. And these could be the spinal cord or the nerves themselves. There is many symptoms. We're going to discuss the changes in our approaches to spinal stenosis during this topic. But I want you to be aware that again, this is a topic that is becoming more and more seen by our specialists and by the general population because of the aging. Now, people can have, if you will, all sorts of symptoms from spinal stenosis.
And that's because it can occur in the neck, the thoracic area or the lumbar, while the thoracic area is the least important by way of frequency, it still can occur even in the thoracic area. So, we look for stenosis or narrowing that can cause symptoms. The symptoms can be of varying nature. That could be a sciatic pain, for instance, that could be back pain, especially on extension, that could be paresthesias or numbness either in your upper or lower extremities. One of the things we hear is that sometimes patients are developing paralysis and they don't know it. They describe it as a heaviness in an extremity. And that is even with physicians that they themselves have this condition. They may not recognize that they're becoming paretic; they may complete a balance problems or even incontinence. And then there's the various syndromes that we have that we're all familiar with in medicine, I presume, central cord syndrome. Where you have weakness in the upper extremities and tingling. I seen a man this week that had a severe central cord syndrome, and yet he was undiagnosed. Cauda equina syndrome. I think we're all familiar with that. Patients have profound pain in the lower extremities, one or both, they could have loss of incontinence. They could have saddle anesthesia, sudden abrupt sexual dysfunction, but especially pain and numbness or weakness in both legs. And finally, there's even a Brown-Sequard syndrome where it's kind of a hemi section of the cord you get the spinal cord. We can have a loss of sensation on the contralateral side, through motor paralysis. So, there's a lot that you can be seen with spinal stenosis, depending upon where it occurs. It's affecting the spinal cord, which goes all the way down from the bottom of the occiput all the way down to the L one, two area, or if it's in regards to the cauda equina, distal to it. I tell patients that you can consider stenosis affecting you several different ways.
Think of a Christmas tree. The trunk of the Christmas tree holds, if you will, the spinal cord, until we get down to the cauda equina. It's the main pipe, if you will, for the spinal contents and where the nerves come out on the side, you can think of as the branches of the Christmas tree, that's the neuroforamen, that can also be tight.
And finally, especially in the lumbar area, you could have what we call lateral recess stenosis. The joints, the facet joints becoming somewhat larger and pressing on the nerves as they come round, if you will, to shoulder. The shoulder of the Christmas tree is where they come out. So, all these things are important for patients and they could have one or more of these conditions affecting them. And it's more important of course, if it's spinal cord, but still, it could be very important, even if it's, they cauda equina, that they could still develop immense paralysis. And it seems to run in families at times. And if one patient has it in, in the lumbar area, they may also have in the cervical area, we have to be aware of that.
Now, how do we diagnose this? Well, first of all, there were other clinical findings, right? And we diagnose it by imaging, MRI scan is ubiquitous now, and it's an excellent study, if we can use it for most patients to look and see if they have this compression. And also in the case of the cervical area and thoracic, you could see if they have myelomalacia or the spinal cord being directly affected.
We can see inside the spinal cord MRI scan. The CAT scan of course its strength is bony abnormalities. So, let's see maybe the neuroforamen where the nerves come out sideways, the branches of the Christmas tree. You could probably see that better than MRI scan. If we have concerns that we have, the neuroforamen been somewhat narrowed, then we might want to get a CAT scan after the MRI scan.
Not always, depending upon the quality, of course, the MRI scan. Generally as a rule, open MRI scans are not as useful as closed MRI scans, but some of our patients are clastrophobic. And if they can't take sedation well, that's, that's certainly an option. Even a moluck on the CAT scan are still used to clarify the area of compression. Plain spine films, generally are not very useful for evaluating stenosis.
So, I don't know if you're following with me so far, but if you're willing, I want to go over some of the costs of this for you.
Host: I would love that Dr. Staner it's absolutely fascinating. And you're making such great points for other providers about clinical findings and things they might not even consider as related to spinal stenosis. So, I would love for you to continue and to explain to other providers how you're helping patients receive faster treatment.
Dr. Staner: Well, we do the evaluations and the, as you can imagine, neurosurgeons are busy people. And in my practice, I did 36 years of surgical practice. In the last five years, I've been doing evaluations for other neurosurgeons. I find this particularly rewarding because I can be there for the patients when they need me most during the evaluation period.
And then afterwards, if they need conservative care or surgical care, expedite this quicker than probably a local physician can just because of my specialty. Now the different causes, generally speaking, we're talking about the aging spine. So, we're talking about the genesis of joint disease. However, there could be a congenital predisposition people with narrow spinal canals from birth are more liable to have this problem though that's not common.
So, what happens when you have a degenerative back? Well, you know, we all think about the joint disease affecting 80 and 90 year olds, but really, your spine starts changing after you're two years old and start walking. And by the time you're 30, you might see some changes in your spine, bulging discs, that are not causing problems.
Even the annular tears by the time you're 40, in that disc. Remember we're talking about a pipe. So, there's many sides to the pipe. It's a 360. It may be one side from a disc herniation. It may be on the other sides, posteriorly in the sides from the ligamentum hypertrophy. Usually occurs again, in the older spine, but there's other causes as well, tumors, trauma, even adipose.
Some people have adipose to the spine, which can cause stenosis. So, there's a lot that can cause this and it's best evaluated by obviously a specialist, in this condition, but a lot of general physicians should be aware of the primary symptoms that occur and can do the initial evaluation as well.
Especially if they see a patient who was complaining of those problems that we've mentioned and is older. What about treatment, et cetera? You know, I've been through many years of seeing treatment and I think fashions come and go and somethings stay that are valuable. I'm going to mention one thing that's of interest because this is a big topic, nowadays. Minimally invasive surgery. Arguably minimally invasive surgery was done in the 1960s, by some people. People don't know that. Endoscopic decompression is fairly recent, but things like Chymopapain for a disc herniation was used in the late 1960s and 1970s. In the 1980s, we had something called a percutaneous nucleotome for a disc herniation, looked like a large trochar with a guillotine on the side of it, so it would slice off and suck parts of the disc inside.
These did not stand the test of time, but the compressive laminectomies have. What has been added to the decompressive laminectomy's in recent years is something called laminoplasty's especially in the cervical spine. We move the lamina, and then decompress it. We put a wedge in there, make the opening in the canal bigger and then reapply it with wires or what have you. So, the canal is bigger and keeping the lamina intact. That has sought some favor in recent years. And especially there seems to be a great trend in the last 10 or 15 years towards fusion. People, I guess of my age, saw little need for fusion unless the spine was unstable or we were creating instability. But I realized that this is the present, if you will, gold standard, many times fusing, and this is where the surgeon's decision comes into scope. Still more recently, even I'm reading an article here in May of this year. Going back to endoscopic decompression, which is favored over fusion by some surgeons. So, we may be going back again to a smaller approach.
We'll see. But in any case, whatever your surgeon chooses, and there's more reasons that I can give in this talk the outlook for surgery on the spine for stenosis is excellent. Even when there's some paralysis, it can help frequently. Certainly, pain is one of the easiest things to help. And the question is what they have to decide on is when to do something.
And when is it necessary? What to do is, not as, maybe as quite as important. Again, there's many alternatives that we have available. At one time, we also had even interspinous devices. Pulling these spinous processes apart, creating more room inside the spine. This seems less favored nowadays.
I think people are getting a little bit away from that, but the gold standard is the decompressive laminectomy with, or without the fusion. And results are really, always have been very good. So the question will be then at an older person, are they able to have the surgery? Are they clinically stable? Are they an anti-coagulants?
What do we have to do with, to prepare them for a surgery? Are they massively overweight? These are questions we have to ask ourselves in the evaluation state.
Host: And are you using ERAS protocols too? As you're telling us how these landscapes have changed and how some of it hasn't changed. Really a fascinating talk, Dr. Staner are you incorporating ERAS? Are you seeing changes in that direction? Kind of give us a summary of what you'd like other providers to know about spinal stenosis and these patients receiving faster, more efficient treatment.
Dr. Staner: I suppose that there has to be a decision along the way about how to treat this, but the first decision is made as to whether or not they do have the condition by way of imaging. And again, I would encourage a closed MRI scan to start with, for most patients. This could be performed by the local physicians and they could come up with a diagnosis most of the time.
Now I would tell you this, that when you say spinal stenosis, remember we're talking about a pipe and you could have spinal stenosis and still have plenty of room for the nerves or spinal cord. So just having spinal stenosis by itself is not that relevant, unless there's compression on the nerves or the spinal cord. But this can all be evaluated frequently by the MRI scan. And then the next step might be to decide what the patient needs by way of treatment. The local physician, they start off with pain medications, with simple pain medication, not prolonged, but for a sudden episode anti-inflammatories, muscle relaxants can all be used.
And then the next stage after that would be a good pain management specialist, board certified in that topic who's an interventionalist who can give some spinal blocks. That might be the next stage, especially important if a person it has to do something the following month and he can't take time off for possible elective surgery, or he's just not a candidate for elective surgery because of his medical condition. Pain management partners with us and can be very helpful.
Host: What a great guest you are. You have a wealth of knowledge, Dr. Staner to impart to both patients and other providers. I can't thank you enough for joining us today.

Joining me in this panel is Dr. Theresa Caridi. She's the Director in the Division of Interventional Radiology, Vice Chair of Interventional Affairs in the Department of Radiology and an Associate Professor at UAB Medicine and Dr. Jesse Jones. He's an Assistant Professor and an Interventional Neuroradiologist at UAB Medicine. Doctors, thank you so much for joining us today. Dr. Caridi, I'd like to start with you. Tell us a little bit about hereditary hemorrhagic telangiectasia or HHT. Are there different types? Tell us a little bit about this condition.
Theresa Caridi, MD (Guest): So, HHT or hereditary hemorrhagic telangiectasia is an autosomal dominant disorder. So, it's a genetic disorder. It occurs in about one in five to 8,000 individuals. And the key characteristics of it are that it results in arterial venous malformations and telangiectasias at various sites. There are various forms of it, but all of the genes that are known to be affected, involve a signaling cascade of molecules that are crucial to vascular development, which is why these individuals end up with arterial venous malformations, which we can just refer to as AVMs and also telangiectasias in places all over the body. So, at one characteristic spot, for instance, is in the lungs and that's known as a pulmonary arterial venous malformation, but these malformations can occur in several areas of the body and need various types of treatment depending on where they occur.
Jesse Jones, MD (Guest): Another common manifestation of HHT is nose bleeding. Many people typically present with nose bleeding, typically around a time of older childhood or adolescence and the nose bleeds can be quite severe, requiring treatment, ER visits and even surgical procedures to address their nose bleeding. Because HHT can affect so many body sites, including the lungs, the heart, the GI tract, and even the brain and spine, it's important that these people are assessed in a center well-versed in HHT with multidisciplinary cooperation.
Host: Well, thank you both for telling us about that. So, Dr. Jones, I'd like you to expand a little bit on the affected populations and more of those symptoms. You talked about nosebleeds, but when does this seem to present itself for referring physicians and internists and providers, what would they notice and when.
Dr. Jones: Well, because like Dr. Caridi mentioned, the disease is actually quite common. You know, up to one in 5,000 people tend to be affected, but nosebleeds are much more common than that. And so most people with nosebleeds, don't just assume they have HHT and the doctors don't assume they have it either. So, it does take a knowledge of the disease in order to get it kind of in a physician's mind that, hey, this patient with recurrent nose bleeding may have HHT, and they should possibly be worked up for it.
There's a series of criteria that we utilize to diagnose these people, including history and physical and genetic testing, now, which is very helpful, but like I mentioned previously, the nosebleeds tend to start fairly early in life and because it's genetic, there's typically a family history of nosebleeds as well, which is very important in the history.
Host: That is important. And what a great point that you made. So, Dr. Caridi, what is involved in diagnosis? Obviously a good history is important, but tell us a little bit about why it's sometimes difficult to diagnose.
Dr. Caridi: Yeah, sure. So, the difficulty in diagnosing HHT is just that it manifests in different individuals and various ways. So, while some patients, most typically one of the manifestations is nosebleeds or epistaxis, not all patients have that. And so they may have a different variant and a different manifestation. As we said before, it can affect many regions of the body. We do use the Curacao criteria, which are four criteria that come along with the patient's history, that can really lend towards the diagnosis, if these are positive or if a few of them are positive. Those include multiple telangiectasias of the skin and mucous membranes, repeat episodes of spontaneous nosebleeds, or epistaxis, visceral vascular malformations and a family history in a first degree relative. So, those are the four Curacao criteria. If patients manifest one or more of these, they should be considered for this disease process. Sometimes this may be an incidental finding on an imaging study, such as a pulmonary AVM. And that would meet one of these Curacao criteria.
So, patients who present with epistaxis, nose bleeding, or they have a manifestation of one of these arterial venous malformations on imaging, an unusual age or presentation for a stroke or other neurologic event, like a TIA, or a family history of any of these things, those patients should be considered for HHT.
Host: Dr. Jones, tell us about some of the standard therapies you would use once you've discovered someone has HHT.
Dr. Jones: Yeah, the therapies are quite tailored to the presentation and as Dr. Caridi mentioned, the presentation can be quite protean. We typically address people symptomatically and also through a comprehensive screening program. So, patients who present with repeated bothersome nose bleeds, will typically see one of our ENT surgeons here at UAB, where we focus mainly on preventative strategies and trying to avoid and more invasive surgical procedures.
These would include things like keeping the patient's mucus membranes moist and well-hydrated, there's things like inhaled, Avastin, which can also be very helpful to prevent recurrent nose bleeds. And if patients do end up needing a surgery, the surgery is typically as minimally invasive as possible. It would be an endoscopic approach using what's called a COBLATOR to really close off some of these telangiatasias in the nose without damaging the nasal septum or other delicate areas of the nasal mucosal membranes. Dr. Caridi is an expert in pulmonary AVMs and she would treat these people through an endovascular technique. I can let her discuss more fully, but as part of the comprehensive screening program, our patients would typically also see a pulmonologist. They would see a cardiologist, a GI doctor for other visceral AVMs and screening for those including capsule endoscopy, as well as a geneticist and a hematologist to manage anemia.
Host: Dr. Caridi, would you like to expand on what Dr. Jones just said?
Dr. Caridi: Yeah, sure. I'll expand on the pulmonary arterial venous malformation aspect of things. If you see cana patient with an incidental pulmonary AVM on imaging, or a symptomatic one, about 65% or even more of those patients actually have HHT so it's an unusual condition to find a pulmonary AVM that's not associated with HHT actually, although it does happen, there are some that are not at all associated with HHT. The point there being, if a physician or a provider has a patient who undergoes CT imaging for some reason, and an incidental pulmonary AVM is found, it should trigger that provider, hopefully with the knowledge provided in this podcast to go ahead and refer that patient to be evaluated for HHT.
The good news is that Dr. Jones and I run a simultaneous clinic essentially on the same day, a couple of floors apart, so that patients come whether as an individual or with their entire family to be screened and worked up for HHT, since this is a genetic disorder, sometimes these patients will prefer to arrive with their families, as a unit so that all of the family can be screened and appropriately managed if they have HHT.
Host: Tell us a little bit, Dr. Caridi about that multidisciplinary approach. We've touched on it a few times. How do you all work together? You just explained how you and Dr. Jones do. And that's great information for other providers about bringing in the family for genetic testing and screening and how you're just a few floors apart. Tell us about some of the other providers that are involved in how you all work together for this type of approach.
Dr. Caridi: So, as I mentioned before, Dr. Jones, and I actually see patients on the same day, in the same general area of our clinic. So, we can tend to see patients one right after the other. We manage most of the typical manifestations of HHT, but patients definitely often have to go on to other services as well. Sometimes those are able to be scheduled in that same timeframe within either that day or within a 24-hour period. So, if they're coming from a distance, they can get everything accomplished in one visit. The other part I'd like to mention about this is we also see pediatric patients, which can be afflicted by this disease as well.
And so we can follow them from pediatric population all the way through adulthood. And we can either do that at UAB or at the adjacent children's hospital, depending on what we're doing with each patient and what their presentation is. But all of these things can be, our coordinators work together, both at UAB and at the children's hospital to accomplish this for our patients and their families.
Dr. Jones: Yeah, I think coordination of care is very important in this population. Because there are so many organ systems affected. So, we work closely with a small but dedicated team of specialists to get these patients seen on the same day, or at least than 24 hour period to get a comprehensive evaluation and management plan put together in one session. As bad as COVID has been in the last year, it has some positive effects in terms of being a game changer in terms of remote access. Before COVID, there was emedicine, but it's really kind of gone to lightspeed in the last several months here. And we've utilized that to our advantage with HHT population to get these people seen sooner, in terms of emedicine visits, which can be a video visit or a phone visit to get some important history and physical exam, and also to coordinate their future care.
Host: Such an interesting topic we're discussing here today. I'd like to give you each a chance for a final thought. Dr. Caridi, what are some investigational therapies you're most excited about?
Dr. Caridi: I'll speak a little bit about pulmonary AVM embolization. I mentioned it a little bit before, but I think there are rapid expansion of devices to be used for the pulmonary AVM embolization. Mostly these involve coils and plugs, but the technology is rapidly advancing. And so we can accomplish the procedures faster, with less radiation and with less sessions for the patient to come back for if they have multiple pulmonary AVMs, for instance. So, I think, in my particular space, I'm excited about the technology and the advancements that are available to us.
Dr. Jones: Yeah, I think medicine is changing fast with HHT in particular. We partnered with the foundation, known as Cure HHT and Cure HHT is a, is an umbrella group that support centers of excellence around the country, which we are currently applying to become such a center to better serve this population. But they also coordinated a lot of important clinical trials. And so at UAB, we'll be starting a trial in conjunction with Cure HHT to look at an investigational agent called politimide is a drug that is taken orally, which has been shown in early studies to significantly reduce the amount of bleeding, particularly from epistaxis, but also bleeding from the GI tract. And we're hopeful by conducting this trial and bringing this drug to HHT sufferers in the Alabama community and throughout the Southeast region that we can significantly improve their quality of life.
Host: What great information and Dr. Jones, do you have a final thought on referring providers and what you'd like them to know about early referral and communication with the referring physician?
Dr. Jones: Well, I think it's very important to have a person to reach and a phone number to call. Dr. Caridi and I are both always available to see new patients and we'd be happy to take any referrals, in the region and take it from there in terms of coordinating their care and working them up.
Host: Thank you both so much for joining us today. And a physician can refer a patient to UAB Medicine by calling the mist line at 1-800-UAB-MIST or visiting our website at uabmedicine.org/physician.

Welcome to UAB Med Cast, a continuing education podcast for medical professionals. Bringing knowledge to your world. Here's Melanie Cole.
Melanie Cole: Welcome to UAB Med Cast. I'm Melanie Cole. And today, we're exploring ascending aortic arch repair and endovascular treatments. Joining me in this panel is Dr. Adam Beck, he's a professor and Director in the Division of Vascular Surgery and Endovascular Therapy at UAB Medicine; and Dr. Kyle Eudailey, he's an assistant professor and a cardiothoracic surgeon with expertise in complex aortic surgery at UAB Medicine.
Doctors, I'm so glad to have you join us today. Dr. Eudailey, I'd like to start with you. I'd like to start with you as the development of endovascular stent grafts in the descending aorta have significantly reduced the number of open surgical repairs being performed, tell us a little bit about the ascending aorta. Is it considered one of the last frontiers of endovascular aortic treatment? How prevalent is it for other providers? What are ascending and aortic arch aneurysms?
Dr. Kyle Eudailey: Sure. So, I think framing it as the last frontier for endovascular stenting is a good way to think about it. We have come a very long way in the field of endovascular repair of aneurysms, really kind of starting back in the '90s with treatment of descending thoracic aneurysms.
The trouble really becomes is that we've learned that the arch and even more specifically the ascending and the aortic root is really a very different animal in terms of how the aorta is structured. The arch has all the flow to the head vessels, which sort of complicates treatment of arch pathology. And then the ascending Is really a dynamic structure where you have significant amount of change with the cardiac cycle. And the ascending aneurysms, as you get more proximal towards the heart, are intimately connected to the aortic valve structure and the coronary arteries, which ultimately perfuse the heart.
So really, what it comes down to is that the anatomy is more complex. And because of that, it's not this concept of just a straight tube that you can slap a stent in. Unfortunately, you have to respect the anatomy of the head vessels and you'd have to respect the anatomy of the aortic valve structure and also the coronary perfusion and that ends up being tricky, would be the easiest way to describe it.
Melanie Cole: Well, I'd like you to expand on that because it was my next question. So challenges, what are some of the limitations to that current practice of ascending stent grafting?
Dr. Kyle Eudailey: So the limitations really, I mean, I guess the easiest way to describe it is how do we classically repair ascending and arch aneurysms? And classically, it's done by open surgery. And we use cardiopulmonary bypass and actually colder temperatures in order to achieve circulatory arrest where we actually don't perfuse the body for periods of time in order to protect the brain. And we resect and reimplant the perfusion to the head. And then, as we get down towards the aortic valve and the coronary arteries, we often are either resecting the valve or sometimes we spare the valve, but we're often then reimplanted the coronary artery.
So really it is a lot of difficult technical surgery. And so in order to do that all endovascularly, you really have to come up with some novel ways to either bypass the head vessels or fenestrate for the head vessels, or we have some now newer technologies that allow us to respect the anatomy of the arch while maintaining perfusion during the stenting process.
As you get down towards the valve, we also have endovascular solutions for the valve, which are transcatheter aortic valve replacement, which we're kind of starting to explore how we can treat the aortic valve and route in conjunction with stenting. That's probably just beginning to scratch the surface of what that all entails, but it gets to the fact that there's a lot of complex structure and anatomy that we have to respect.
Melanie Cole: Well, certainly. And Dr. Beck then, why don't you talk about some of the new technologies or protocols standards or even diagnostic tools for the treatment that you feel are worth talking about and how have advances in radiologic imaging really augmented your capabilities to treat these conditions?
Dr. Adam Beck: If I can maybe just back up just for a moment, just to reiterate a couple of things that Dr. Eudailey said. So some of the limitations of doing endovascular repair in the ascending aorta and arch of the aorta are anatomic and some are physiologic. And we also really should talk about a couple of different disease processes just to parse it out a little bit more.
So the operations that we do, that the cardiac surgeons do in the ascending and arch are most commonly for aortic dissection and for aortic aneurysm and both of those have their own considerations for doing an endovascular repair. And just an isolated ascending aneurysm or dissection is much different than a dissection or aneurysm that extends through the arch of the aorta for all the reasons that Dr. Eudailey mentioned about the brachiocephalic or head vessel perfusion.
From my standpoint, I have had a longstanding interest in complex endovascular aortic surgery and mostly for the thoracoabdominal aorta, for the portion of the aorta that has branch vessels to the intestines and kidneys. That is still a frontier in many ways. But the ascending and arch of the aorta have some technological anatomic physiologic challenges that we don't have in the visceral aorta. But we've learned a lot from the visceral aorta in the way that we treat branch aortic diseases. And so some of those techniques and technologies are being applied in the arch appropriately or inappropriately and we're sort of learning that as we go.
From an imaging standpoint, there've been many advances in imaging along the way since we started doing endovascular aortic repair. Some of them were preoperative, that's with the way that we do CT arteriograms and use 3D reconstruction for preoperative planning. But we've also made a lot of advances in the operating room with 3D overlay imaging where we can actually fuse the patient's intra-operative imaging to their preoperative CT scan, which is almost like playing a video game in a way, because we can actually overlay their anatomy and we can see it on the screen while we're placing the devices into the aorta.
And the next frontier from an imaging standpoint is actually non-fluoroscopic imaging, so non-radiation-based imaging where we don't actually even have to perform fluoroscopy while we're deploying the devices in the aorta and revascularizing the branch vessels. And that's actually not too far down the road. We're going to be one of the first institutions in the world to have access to that. So we're pretty excited about that technology that's coming down the road.
Melanie Cole: Dr. Eudailey, can you give us a little overview of technical aspects you'd like other providers to know about as you have expertise in these complex surgeries? What would you like to share with other providers to help achieve better outcomes? And you can speak at this time as well about patient selection and how important that is in this case.
Dr. Kyle Eudailey: Sure. I mean, I think you really kind of are hitting the nail on the head speaking to selection right? And Dr. Beck just talked about all the advances we have in terms of preoperative imaging. But really the reason that's important is because preoperative planning, it plays a major role in these cases. The variability in anatomy between patients can be pretty significant. And that variability means that there's not a one-size-fits-all solution for most of these patients. And so there's a lot of preoperative planning and selection that happens on the front end. And I think that's probably the most important aspect to understanding how we apply these sort of newer technologies to patients.
The other thing to consider is that open surgery is actually a very good option for people. And so there's a high bar that we have to overcome with open surgery. And so these people that we think we'd get the most benefit or gain the most benefit from endovascular solutions are the people who are higher risk for open intervention. And those are people who have existing cardiopulmonary disease or other co-morbidities that make their recovery harder because the open repair of these operations. And by open, I mean, a true open heart solution, which usually requires a sternotomy and several hours in the OR. It's just a big operation and people get through it, but the recovery can be hard. And so it's a better long-term solution for younger patients. But it's sometimes not the best solution for older patients. And so the preoperative planning, the patient selection, that kind of deciding who is going to benefit the best from some of these technologies based upon their comorbidities and also their anatomy is a really important step to how these technologies get applied.
And Adam and I have conversations all day and night about these people and whether or not they're anatomically suitable and whether or not this is the right way to move forward. And often, the scrutiny for them to get into some of these trials is hard too is what is I would say.
Melanie Cole: Dr. Beck, you touched on this a little bit before, but TEVAR or thoracic thoracic endovascular aortic repair, how has it helped to make ascending TEVAR a more reproducible, reliable procedure? Tell us a little bit about the success rate of what you gentlemen are doing at UAB Medicine. How have been your outcomes?
Dr. Adam Beck: TEVAR has been around a little while. Usually, when we say TEVAR, we're talking about the descending thoracic aorta, as you alluded to. That really has almost completely replaced open surgery in the descending thoracic aorta, as far as isolated surgery or that isolated segment of the aorta. The outcomes are excellent. The morbidity or complication rate and mortality of those operations is much less than an open surgery.
Thoracoabdominal aortic surgery is becoming more and more endovascular, although we still do a lot of open thoracoabdominal surgery for various reasons. Some of those that Kyle pointed out in younger patients are those with connective tissue disorders or infectious processes. As I think both of us alluded to earlier, the ascending aorta is a lot different because of maintaining coronary flow, maintaining the structure and function of the aortic valve. But also it's a very dynamic portion of the aorta, just because of the cardiac motion, respiratory motion. So it's a really demanding area of the aorta when you put a device that's made out of metal and fabric into it. So those devices can fatigue, they can fracture, they can be displaced, they can migrate and all of those things can lead to a failure of your repair. So those are challenges that biomedical engineers are working on, but we also work on in terms of our patient selection.
So it's a very small subset of patients that we actually would do an endovascular repair in the isolated ascending aortic pathology. And this is not a segment of the aorta that I operate on as a vascular surgeon. That's a segment of the aorta that cardiac surgeons operate on. And so that's why this collaboration is so important because I do a lot more endovascular surgery. Dr. Eudailey does all of the open surgery in that segment of the aorta. So we work together to try to pick the best patients for the best procedure for them.
Really the short answer to your question is we're still not doing a lot of ascending aortic repair. There are certain patients with certain conditions that are actually pretty straightforward in that segment of the aorta, but a vast majority of those patients in 2021 are still best served with an open operation.
Melanie Cole: Well, thank you for that. And I'd like to give you each a chance for a final thought. Before we do that, Dr. Eudailey, based on what Dr. Beck was just saying about your collaboration and given the complexity with increasingly complex treatment algorithms that are adding new options to your armamentarium of available therapies, how important is this multidisciplinary care, this collaboration between different specialties for these complex patients?
Dr. Kyle Eudailey: Yeah, I would say that this type of collaboration is everything. I mean, this is what makes something kind of this special possible here at UAB. There are not a lot of centers across the US that are even close to doing this type of collaboration and certainly not a lot that are even applying it as frequently as Dr. Beck and I are. And it really makes our decision-making better on both ends. What it has allowed is that it allowed us to be a part of some very exciting trials and development and things coming down the line from what Dr. Beck was saying in terms of biomedical engineers in these companies.
In 2021, we are kind of using this in a very small selected group of patients, but there is an exciting pipeline of technology to where this should be more widely available. And we are really on the cusp of it here. And one of the only reasons we're on the cusp of it here is because this type of rapport exists between us to where we can say, "Is this open? Is this endo? Let's consider this. Let's consider that" and that is a unique aspect to what's going on here at UAB, which I think is exciting.
Melanie Cole: This whole episode is fascinating to me. So Dr. Beck, first last word to you here. Tell us a little bit about any promising new therapies, any game-changers that you see coming down the pike and down the horizon, and really what you'd like other providers to know, any clinical trials or research you're doing at UAB.
Dr. Adam Beck: Well, I'll tell you, one of the most exciting things about us is I've been in practice for about 11 years now. And over that 11 years, I've seen this transformation of open aortic surgery into endovascular aortic surgery. And I've kind of watched this march towards the aortic valve. And the really exciting thing to see is that we're getting there and we're actually having successes and we're seeing devices in clinical trials. So as of right now, there are actually multiple clinical trials that allow us to treat the arch of the aorta, to treat the ascending aorta that we're right on the cusp of having available to us at UAB.
And I will also point out and it would be remiss for us not to say this, but we also have a really nice collaboration with the cardiologists here at UAB. So as we move even closer to the aortic valve where the coronaries arise, it will be very important to have them involved as well. And this is not just a virtual collaboration. This is a real collaboration. We all actually enjoy being around each other and talking about these clinical problems, which is really a pretty special thing that we have here that I don't think people appreciate elsewhere.
Melanie Cole: Dr. Eudailey, last word to you. What would you like other referring physicians to know about when you feel it's important that they refer to the specialists at UAB Medicine and anything else you'd like to share?
Dr. Kyle Eudailey: I think the important thing for people to know is that there are some exciting options here and they will work for some patients who are higher risk for traditional options. We're pretty honest about who it may work for and who it may not work for. And what we do we have available here is truly kind of amazing. And we're one of very few centers in the United States who have all these options available and I think that it's important for people to understand that especially in the Southeast, that we're always happy to evaluate people and we try to be pretty quick and responsive and the evaluation could be turned around pretty quickly for these patients, which is sometimes people worry that it takes a while for them to kind of be fully evaluated, but we're usually pretty good about having a pretty decent turnaround within a couple of days in terms of whether or not we think somebody's going to be feasible. And we also have a very good system of remote review of images, which I think is excellent, and either of our offices can set that up for referring providers.

And today, we're discussing myopia control treatments in the pediatric world that are becoming more popular. Joining me is Dr. Elise Agostinelli. She's a pediatric optometrist and clinical instructor at UAB Medicine. Dr. Agostinelli, thank you so much for joining us today. Can you tell us a little bit about nearsightedness or myopia and what it is?
Dr Elise Agostinelli: Thanks so much for the opportunity to join you on the podcast, Melanie. This is a very exciting topic I get to talk to you about today. Essentially, nearsightedness or myopia means that the eye is too long and farsighted means that the eye is too short. I've actually always thought these terms nearsightedness and farsightedness were named backwards, but people that are near-sighted see better at near than at a distance and that's the opposite for farsighted.
Single vision prescription glasses and contact lenses are used to correct myopic vision, but fail to treat the underlying problem. When a baby is born, they go through a process called immature fixation. When they are born, there's a broad spectrum of refractive error that becomes more and more narrow.
By age one or two, a child will have very little refractive error. However, with each passing year, their eye grows and potentially develops myopia. So the average age in clinic that we usually see kids develop myopia is about 11 years old.
Melanie: So it's about 11 years old. Tell us a little bit about the clinical presentation, doctor. Is this a cause for concern in younger children and how do we know?
Dr Elise Agostinelli: So usually, the pediatricians do a really great job of screening children, and they'll send them to the pediatric optometrist or ophthalmologist if they notice that they're having difficulties. Myopia at an earlier age can be a cause for concern. Having myopia as a baby or a young child may uncover a more complicated picture. It may be the reason for a child's initial medical referral and an important clue to an underlying systemic or ocular condition. Some of the diseases that are associated with high myopia as a baby or a child is Marfan syndrome, Ehlers-Danlos syndrome, albinism, cerebral palsy, sticklers disease, and Down syndrome.
So even if the pediatrician didn't send a child to us at the clinic, some of the signs that a child may be myopic is having difficulty seeing things at a distance, seeing the board, possibly squinting, or even sometimes headaches. So if the child is having any of those symptoms, it's important to get them in the clinic right away.
Melanie: So do you feel that this is on the rise in our children, doctor? Is there anything about our kids' behaviors? As I was doing my research, I learned a little bit about spending time outdoors versus screen times, and that that can have a positive effect on a child's vision. Can you speak to that just a little bit?
Dr Elise Agostinelli: Yeah. And there are definitely some risk factors that tend to cause myopia or nearsightedness. Unfortunately, one of the main ones is out of our control. For one, the most common race that's myopic is the Asian population. Also, having parents that are myopic is a huge risk factor for myopia. You're actually two times more likely to be myopic if one parent is, and you're actually five times more likely to be myopic if both parents are myopic.
The studies have actually shown that parents with greater than 12 years of education are more likely to have myopic children. However, like you were saying, Melanie, there are some environmental risk factors that you can control the child's chances of becoming myopic or their progression.
The study have shown that increased time on electronics at near have shown to increase myopia. To our myopic patients, we always tell parents to limit their c hild's screen time to 30 minutes to one hour a day. Most parents are usually pretty happy about this recommendation as they already have a hard time limiting their child on devices.
And like you were saying, it's also been studied that increase outdoor time or vitamin D can delay its onset or reduce its progression. So that's just another reason why it's really important for children to stay active. The actual time that they say in the studies have shown to limit the progression is actually 90 minutes of outdoor time a day.
Melanie: Wow. This is such an interesting topic. I mean, we can all certainly use that advise, doctor, about screen time, because we're all in, especially with COVID, on screens all the time now. And I've noticed my eyes feel like they want to close on their own by the end of the night, you know? So tell us a little bit about management and your best advice and certainly management in the pediatric population that other providers are dealing with as well.
Dr Elise Agostinelli: So besides limiting screen time, there's actually different treatment modalities we do as eye care providers to help slow down its progression once a child has actually been diagnosed with myopia. Each treatment recommended is usually patient dependent as they all have high success rates. The average increase in myopia per year for a child is about half a diopter, but that is just the average. Especially with the pandemic, we've seen large jumps in myopia per year due to increased screen time for virtual schooling.
The treatment that I use the most frequently in my clinic is the use of 0.01% atropine. This is a very diluted form of atropine that actually helps to slow down the elongation of the eye because remember we were talking about how nearsightedness means that the eye's too long. The other treatment modalities that are frequently used are multifocal contact lenses and ortho-K contact lenses. These contact lenses require multiple visits to fit the patient in the appropriate lens.
The multifocal contact lenses are actually shaped like a bullseye and have two basic portions for focusing light. The center portion of the lens corrects nearsightedness so that a child's distant vision will remain clear. But it also focuses light directly on the retina. The outer portion of the lens actually focuses power to bring the peripheral light rays into focus in front of the retina. The animal studies have shown that bringing light in front of the retina cues the eye to slow its growth.
There's also ortho-K lenses, which stands for orthokeratology. These lenses are the use of gas-permeable lenses that are actually worn when you're asleep and removed upon wakening. These lenses create a temporary change in the shape of the cornea. Therefore, glasses or contacts do not actually have to be worn during the day, but they must be worn every night to be effective, these contact lenses. If you think about it, it's kind of like a retainer for the eye that you wear at night and removed during the day.
Melanie: Well, thank you for that explanation. And for other providers, how can they counsel their patients to begin treatment? Have you seen that some parents are resistant to treatment for their children? Counsel other providers here, doctor.
Dr Elise Agostinelli: Actually, these treatment modalities have not been FDA-approved yet, but the way we actually have to convince our patients to go on with the treatments is so, you know, why not just give them glasses or contacts. but the concerning thing about myopia is it's side effects. These side effects include increased risk of glaucoma, retinal detachment, cataracts, and choroidal degeneration.
All these risks are actually due to the increased size of the eye and globe expansion of it. The unfortunate thing is these side effects are actually sight-threatening and the patient or child could potentially go blind from them. Usually, this is enough to help the parents make a decision as they are willing to kind of do any treatment for their child to prevent them from developing any further problems or conditions.
Melanie: Wow. That is very important information. Thank you so much, doctor, for joining us today.

There is no commercial support for this activity. - TranscriptionMelanie Cole: Welcome to UAB MedCast. I'm Melanie Cole. And today, we're discussing the role of physical medicine and rehabilitation in stroke rehabilitation. Joining me is Dr. Amber Clark. She's an assistant professor and a physical medicine and rehabilitation specialist at UAB Medicine. Dr. Clark, it's a pleasure to have you join us.
And this is a really great topic and kind of a new burgeoning field. So tell us a little bit about the role of PMNR in stroke rehabilitation. And even while you're doing that, tell us a little bit about physical medicine and rehabilitation in general.
Dr. Amber Clark: Absolutely. And it's great to be here. I'm always happy to really promote my specialty. And so first of all, physical medicine and rehabilitation was born out of a necessity That was seen when we had our soldiers coming back and we wanted to reintegrate them into society, there was really no specialty that assisted with that. our soldiers were coming back. They'd had amputations, they'd had brain injuries, they were different.
And the grandfather of physical medicine and rehabilitation worked towards correcting that issue. So he worked with physical therapist to address all of the deficits that our soldiers had. And that's what we really focus on in physical medicine and rehabilitation. We work with therapists, whether that's physical therapists, occupational therapists, and speech therapists. And we have three tenets in our specialty. It's improving independence, quality of life and restoring function. So yes, we are one of the newer specialties in the history of medicine, but I would say our birth was really in the 1920s.
So with that said, stroke rehabilitation, we like to get involved in stroke rehabilitation really at day one. With those same tenets that I previously mentioned, improving independence, quality of life, restoring function, stroke rehabilitation is a continuum. So we have the acute care settings where patients just had a stroke, the primary team is working to medically manage the stroke from their standpoint. But with rehab, we get in. Yes, the primary team is managing the primary stroke, but there are other complications looking at a rehab perspective that can happen after strokes. One of those being spasticity development.
Another being the point that our patients often have premorbid conditions before they come to the hospital. So in my experience I've seen, we have kind of resurgence of musculoskeletal issues, especially in the side that has been involved. So whether they've had a previous biceps injury or rotator cuff insufficiency, that's heightened or they're starting to already get shoulder pain just based off the fact that the affected side is no longer really getting the input that it needs and we can start have gravity taking place so we can get subluxation, so that's painful.
I mentioned spasticity. And spasticity was a great thing because that tells us that the patient is starting to recover from the stroke, but sometimes people get stuck there in that spasticity phase. So what spasticity can start to do, it can start to cause pain, it can start to interfere with therapy. And, if it gets bad enough, it'll start to interfere with hygiene. And so the role there is to really notice and act fast if I see that happening, so that when we're looking at the continuum, so after acute care, we have post-acute stroke recovery, we can do outpatient home health. We just want to get at the forefront of these complications happening on this continuum.
Melanie Cole: Well, it certainly is important. And as you say, getting them really into this type of rehabilitation right away on day one, which is also what they started doing after heart attack. You know, that was something that it was bed rest for a long time. But now really, they are getting up and doing cardiac rehab right away, day one. So we've seen the change. We've seen the importance of this. Does everyone need that same rehabilitation following a stroke? Do they need inpatient rehabilitation or are there other options? Is it mostly something that started in patient and then they continue it just like cardiac rehab with phases?
Dr. Amber Clark: So the answer to that is no. And that's not to say that every patient doesn't need some level of rehabilitation. But inpatient rehabs, there are certain criteria. There are things we're looking at for patients to qualify. Now, I will concede and say that definitely studies have shown that patients do very well or tend to do better when they are immersed in an inpatient rehab setting. And there are distinctions made between these levels of rehab. Inpatient rehab being three hours of therapy a day, where patients need to show that they meet two out of three of the therapy modalities or disciplines that we offer being speech therapy, physical therapy and occupational therapy.
But there are also again other criteria that we're looking at along with their medical complexity and the thinking about, number one, how they're doing already on the acute side with the therapist and prognostication of it. So we have some patients that do have a stroke and stroke patients, depending on the severity of course, can really progress rapidly. So I can see someone one day and I'm like, "Okay. Maybe they could benefit from inpatient rehab." Or one or two days later, they're up and walking more than household distance, which is 60 feet, they are not needing a lot of assistance whatsoever. And at that particular point, no, inpatient rehab would not be the best for them. They could discharge home with either having home health or they could go straight to outpatient therapy.
And I know a lot of times we want to push for inpatient rehab, but it's not always the most appropriate setting for these patients. And honestly, at the end of the day, too, as it is a hospital, we're still putting our patients at risk of catching hospital-acquired infections and things like that. So as I mentioned before, it's definitely a continuum, but no, every patient does not need inpatient rehab.
Melanie Cole: So then tell us a little bit more about acute care while they're awaiting the next phase of the recovery process. So when are you consulted? And tell us a little bit about how the process works for referring physicians.
Dr. Amber Clark: So I am consulted when the primary team deems that it's appropriate. Ideally, as I mentioned before, we like to be involved from the beginning. So particularly with stroke patients, and typically there are two questions that can be asked. Usually, when we are consulted, the primary question being asked is is this patient appropriate for inpatient rehab?
Sometimes it's hard to answer that question because the patient hasn't yet been seen by physical therapy or occupational therapy or speech therapy, because those are important points of information that we're also looking at to include in our assessment and to make the appropriate recommendation. But again, we like to get consulted earlier in the phase, in stage one.
And some of the things that we can also be consulted for is to really counsel patients and counsel their families on rehab prognostication. So what patients can expect as they move on this continuum in rehab and managing that spasticity and addressing musculoskeletal issues even as I mentioned.
I've done trigger point injections on patients. Again, just because they had a stroke it doesn't mean that all other premorbid issues go out of the window. And as physiatrists, we are especially trained in being experts not only in the nervous system, but also the musculoskeletal system as well. And we have a wealth of knowledge, and kind of merging those two together. So from that, we're able to see more than what we see on the surface with patients. And that's all aiding in the quality of life, even on the acute care side.
So we'll get the consult. I'll go see the patient. If the question is if they qualify for inpatient rehab, I'll assess them. If therapy has already seen them, I'll look at those notes. If they are showing that they're already appropriate, I'll let the team know that. If the patient is "low level,' meaning like they are requiring a lot, a lot of assistance from our therapist, maximum assistance, total assistance and it is obvious at this particular moment they wouldn't be able to withstand three hours of therapy a day. I may make suggestions like we could look into a lower level of rehab, like a skilled nursing facility where they get maybe one or two hours of therapy a day and work their way up. Or it could be the case like this patient is walking 210 feet, they're completely independent with grooming. They're modified independent, which means that they're independent, but may just need an assistive device. If they're at that level and showing that they are well enough to go home and be safe at home, I'll make that recommendation as well. But all the while I'm also thinking about what are other barriers this patient may have, are there things that we're missing that needs to be addressed. And, if they do discharge home or even to another inpatient rehab facility or skilled nursing facility, I make sure that there's follow up in my stroke recovery clinic, just to make sure nothing falls through the cracks. So I found that that is an issue as well.
Melanie Cole: Such important points. And it's so interesting to me, Dr. Clark, how really it's all come together, this multidisciplinary approach. And you mentioned physical therapy and occupational therapy or speech therapy, there's all these different departments working together. As we wrap up, really how can physical medicine and rehabilitation continue to advocate for and improve the wellbeing, as you mentioned there are comorbid conditions, for the stroke population and just kind of reinforce the importance of that multidisciplinary approach at UAB Medicine.
Dr. Amber Clark: Yeah, I think we as physiatrists and PMNR in general, one of the things that we need to do is continue to show our colleagues the multiple things that we can offer. Particularly here at UAB, I know a lot of our colleagues in different departments recognize that we have an inpatient rehab facility. And when they think of staying in rehab, that's what is thought about. But we have a wealth of outpatient clinics here to serve the population that we treat. So we have musculoskeletal clinics. We have spina bifida clinics. Of course, we have stroke clinics. We have spinal cord injury clinics, traumatic brain, and we have all of those are very multidisciplinary. We have rehab psychologist here that we work very closely with not only in our inpatient rehab facility, but we also refer a lot of patients on the outpatient basis as well.
And I would like to encourage my colleagues and physicians in other departments how they can be advocates as well for the stroke population. One would be, we are very blessed to have a strong team in our department here at UAB. But that's not the case all around Alabama or really within the United States. So if you have a patient that clearly has some sustained deficits and they have not fully recovered after stroke, I'd encourage you to reach out and see what physiatrists are in the area that may be able to assist your patients. And then also empowering patients to have listed questions when they go to these providers.
A lot of times, and I've done the same thing, like when I'm going to my physician, you'll have a list of questions in my head. And if I don't write it down, I'll forget. And a lot of times and we're dealing with patients that have disabilities and we know that strokes are actually the leading cause of long-term disability within the United States and that two-thirds of stroke survivors actually go on to have lasting deficits, that's important.
So we want to empower our patients that, yes, you may have had a stroke. But you have the ability to advocate for yourself. It's okay to ask questions and go from there. I think that those are two things that I would definitely suggest.
Melanie Cole: What great information. Thank you so much, Dr. Clark, for joining us today and really telling us how PMNR is involved in stroke rehabilitation. And a physician can refer a patient to UAB Medicine by calling the MIST line at 1-800-UAB-MIST, or they can always visit our website uabmedicine.org/physician.

I'm Melanie Cole, and I invite you to listen as we examine inequalities and disparities in pediatric epilepsy. Joining me is Dr. Kathryn Lalor. She's an Assistant Professor and a Pediatric Epileptologist at UAB Medicine. Dr. Lalor, it's a pleasure to have you with us.
And data has shown that people from racial or ethnic minority groups are less likely to receive preventative health care and across the board, various ethnic groups have faced a disproportionate health burden. Can you tell us a little bit about some of the factors contributing to the health care disparities in children with epilepsy? Are there studies that show whether race and ethnicity were associated with seizure remission in this population?
Kathryn Lalor, M.D. (Guest): Of course. And thank you for having me and having me to talk about this important topic. Yes, we know that, there are about 54,000 people living with epilepsy in our state in Alabama and children and the elderly are most affected and the most vulnerable populations. Much of the data we have about health disparities in epilepsy is focused on adults, the adult population.
We know that adults with epilepsy have decreased levels of education. They have decreased incomes, they have decreased health status. And I think that our role as pediatric neurologists and epileptologists is to really take this data and see how we can set these children up for success as best that we can. We know that the morbidity of disease and the effects of discrimination across socioeconomic and racial and ethnic outlines can accumulate a real lifetime and lead to some of these worse outcomes.
Host: That certainly is true. And this is such a good topic we're discussing here today, Dr. Lalor. Are there any factors unique to your region and are there any factors which could improve the care of say students with epilepsy and seizure disorders in the schools? As a pediatric epileptologist what do you see in your general region about factors that could contribute or could help the situation?
Dr. Lalor: The south itself, is becoming known as the epilepsy belt. And some of this is due to sort of adult factors that can lead to epilepsy later on in life. However, I think some of the disparities in care for people with epilepsy are present across the age range. And we don't understand all of the factors for this. And it's very important that we keep doing research and looking for these factors, but we know that people in the south are less likely to see a neurologist if they have epilepsy, much less an epileptologist or epilepsy specialist.
And specifically, we know that African Americans are less likely to receive advanced treatments for epilepsy, such as epilepsy surgery. We also know that they face more stigma from their epilepsy, which is still a very big problem, across the epilepsy population. And we don't understand all of the factors for this yet. So, more research is definitely needed. Another factor in Alabama is that we have a large rural population and the neurologists and epileptologists are really sort of located in very focal areas. So, access to care can be a big issue. And then in schools, a lot of our schools don't have the funding for full time nurses to be present in each and every school in the district. And this can lead to safety issues for students with epilepsy and also can limit what they have access to within the school. And because many students for their safety, are prevented from being able to attend sports practices, field trips, or even sometimes attend school itself if a nurse is not able to be present.
Host: This is really such a complex topic Dr. Lalor. So, what are some things that you feel, in your opinion, that can be done on a system level to try to rectify some of these disparities? You can speak about maybe Telehealth, as you were talking about reaching out to the rural areas. Please share for us your experiences of prioritizing diversity, equity and inclusion. And express why it's important for an academic medical center, such as UAB and neuro department to do this for the community.
Dr. Lalor: So, speaking of Telehealth and Telemedicine, the pandemic has been such a hard time for so many people across the board, but when, the silver lining that has come from it is that Telemedicine has ramped up a lot. And the access to Telehealth visits, has really increased for a lot of our patients. And, I think the difficulties with living in a rural area and having low socioeconomic status, can limit families from being able to get to appointments. And so Telemedicine has really improved care for these families. And I think that on a systems level, we really, as physicians need to be advocating for these patients.
And then as you know, policy makers, insurance providers need to understand that in order to provide care for many of these patients, we need to continue to have access to Telemedicine and this needs to really be incorporated into the standard of care even moving forward after pandemic concerns are no longer present.
Some other things I think, research focused on factors of disparities, especially in children, but also looking at caregivers of children with epilepsy, especially those that have a lot of co-morbidities such as intellectual disability and require really a lot of individual care and one-on-one care. We know that in those families of children with epilepsy like that, there is decreased quality of life of the whole family. And so looking at factors that contribute to that and how we can improve them, I think that's very important. And then, increasing education about epilepsy, across the community to try to decrease stigma and improve awareness and safety for these patients, both in schools and also just in public. We are very fortunate in Alabama to have a strong chapter of the Epilepsy Foundation. And they do a lot of work in this area, but we, as physicians can do more.
And then I think for ourselves, one thing that individual providers can do is really do a lot of self-reflection on our own implicit biases and assumptions that we may make without even realizing it. Because these may end up being factors in access that certain patient populations have to certain treatments like the advanced care, like epilepsy surgery as I was discussing earlier. And I think we really need to educate ourselves on how to be culturally competent and also be aware of our own biases which, which everyone has just based on their background. And then really listen to our patients and understand that many of them may be uncomfortable with the healthcare industry, and not really understand how to navigate it. So, we need to be the ones asking the questions and ensuring that families have the support they need to care for their children with epilepsy.
Host: Very well said. I agree with you completely. And I was going to ask you about in your personal experience, how you've seen this materialize at UAB and that working with people from different backgrounds or cultures can present a unique opportunity and unique challenges for collaboration and creativity. As we wrap up, Dr. Lalor, please tell other providers what you would like them to know about epilepsy at UAB Medicine, when you feel it's important that they refer and where you think the best opportunities to examine inequalities and disparities in pediatric epilepsy lie for the future.
Dr. Lalor: I have seen, on a patient specific level, sort of some of these implicit biases play out in discomfort with the hospital and sort of low health literacy, really lead to communication issues between providers and parents. And I think there's the potential there for us to sort of not rectify those and give poor care for our patients. So, I think that's really on us to meet patients and parents where they are. And really try to understand their background and where they're coming from, so that we can help them make the best decision for their children. As far as, our Epilepsy Center here, it's recommended that any patient with epilepsy who is still having seizures after trying anti-seizure medications be referred to an Epilepsy Center for evaluation of other non-medication treatments that they may qualify for. We also have, many general neurology providers who are very experienced at treating epilepsy and we're of course always happy to see anyone who either has seizures or there is just concern that they may have seizures.
And then I think, areas of focus for us, in addition to educating ourselves, sort of the low hanging fruit is really advocacy, advocating for our patients and also in the community and at a state level, pushing for more policies and legislation that help our patients, for things like improve safety in schools, improves nursing here in schools, access to Telemedicine even after pandemic alterations are removed from healthcare. And then I think that research really needs to focus on factors that lead to both disparities in healthcare for adults and children, but also how your experience with the health care industry as a child then leads to some of these disparities we see in adults with epilepsy. And so that we can really take the best care of these patients that we can, and also set them up for success in their adult lives.
I will add that we now have an Epilepsy Transition Clinic to try to help these families and patients move from pediatric to adult neurology care. And then there's also the Step Clinic here for patients with complex medical needs and help them move from the pediatric primary care, but also specialty care world to the adult healthcare system.
Host: That transition to adult medical care for patients like this is challenging, but that was really great information. And I thank you so much, Doctor for joining us today.
