MedicalResearch.com Interview with: Emily J. Gallagher, MD Assistant Professor of Medicine Endocrinology, Diabetes and Bone Disease Icahn School of Medicine at Mount Sinai  MedicalResearch.com: What is the background for this study? Response: Multiple Endocrine Neoplasia Syndrome Type 2 (MEN2) is an inherited endocrine disorder characterized by the development of pheochromocytoma, medullary thyroid carcinoma (MTC) and parathyroid tumors. It occurs due to activating missense variants in the RET gene. The estimated prevalence of MEN2 is 1 per 30,000 in the general population. Through a collaboration between The Center for Genomic Health, the Charles Bronfman Institute for Personalized Medicine, and the Division of Endocrinology at Mount Sinai, our aim was to investigate the prevalence and clinical manifestations of pathogenic RET variants in the multi-ethnic BioMe Biobank. The BioMe Biobank is an electronic health record-linked biobank with exome sequencing data available for more than 30,000 patients recruited across The Mount Sinai Health System. (more…)

MedicalResearch.com Interview with: Jagat Narula, MD, PhD Philip J. and Harriet L. Goodhart Professor of Medicine (Cardiology) Associate Dean for Global Health Director of the Cardiovascular Imaging Program Mount Sinai Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: Atherosclerosis has been linked to causing erectile dysfunction (ED) in the majority of patients with this cardiovascular condition, but researchers have not had the means of demonstrating atherosclerosis in penile arteries until now.  This unique study uses advanced imaging to detect how strong the association actually is.  For the first time, researchers have used advanced imaging of penile arteries to show a link between atherosclerosis and erectile dysfunction (ED).

Accidents & Violence, Author Interviews, Heart Disease, Inflammation, JACC, Lipids / 18.03.2019

MedicalResearch.com Interview with: Dr. George Dangas MD PhD Professor of Medicine, Cardiology Mount Sinai Health System MedicalResearch.com: What is the background for this study? Response: Widespread use of statins targeted to decrease levels of low density lipoprotein cholesterol (LDL-C) below 70mg/dL are recommended by guidelines. However, residual cholesterol risk may only be one part of the residual risk equation. Indeed, Biological inflammation has long been known as a pathophysiological mechanism of atherosclerosis and the recent CANTOS trial opened new therapeutic perspective by demonstrating that inflammation modulation via selective interleukin-1β inhibition could result in improved diagnosis in patients with coronary artery disease. However, the prevalence and impact of a residual inflammatory biological syndrome in patients with controlled cholesterol risk is unclear. (more…)

MedicalResearch.com Interview with: Paul Cagle, Jr. MD Assistant Professor of Orthopedic Surgery Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? What are the main findings ie What are some of the significant comorbidities?  Response: In this study our goal was to better understand what medical issues (medical comorbidities) can cause trouble or issue for patients with a proximal humerus fracture (shoulder fracture).  To tackle this issue we used a large national sample of patients and sorted our the different medical issues the patients had. We found that patients with increased medical issues had longer hospital stays and higher use of opioid medications (pain medications). (more…)

MedicalResearch.com Interview with: Darwin Chen, MD Assistant Professor of Orthopedic Surgery Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? What are the main findings? Response: Periprosthetic joint infection unfortunately remains a leading cause of total knee arthroplasty failure. One method of mitigating the risk of PJI is to use antibiotic loaded bone cement in a prophylactic fashion. While the use of antibiotic cement makes inherent sense, the decision is not as simple as it seems. There are potential side effects such as renal damage, antibiotic hypersensitivity, and antibiotic resistance. Antibiotics decrease the mechanical strength of cement fixation, which may impact component loosening. Additionally, antibiotic cement is significantly more expensive than standard cement, driving up cost. Currently there is no consensus on if antibiotic cement truly reduces infection risk and there are many conflicting studies. The purpose of our study is the use a large national database to evaluate real world utilization patterns of antibiotic cement, and assess outcomes, complications, and cost associated with antibiotic cement usage. Our hypothesis was that antibiotic cement is associated with a decreased risk of infection and no increased risk of systemic complications.  (more…)

MedicalResearch.com Interview with: Dr. Alexis Colvin, MD Associate Professor of Orthopedic Surgery Icahn School of Medicine at Mount Sinai  MedicalResearch.com: What is the background for this study? Response: 40% of all opioid overdose deaths involve a prescription opioid and orthopaedic surgeons are the 3rd highest prescribers of opioids.  Set guidelines for post surgery opioid prescriptions have not been established.  Arthroscopic knee meniscectomy is one of the most common orthopaedic procedures.  The purpose of this study was to determine how many opioids were being prescribed  among a group of six sports fellowship trained orthopaedic surgeons versus how many patients were actually using.

Author Interviews, Dermatology, Surgical Research / 05.03.2019

MedicalResearch.com Interview with: Hooman Khorasani, M.D. Cosmetic Surgeon & Mohs Skin Cancer Surgeon Icahn School of Medicine at Mt. Sinai MedicalResearch.com: What is the background for this study? Response: Lipomas are tumors composed of mature fat cells located just beneath the skin surface. They are the most common soft tissue tumor and are estimated to occur in 1% of the population. These benign tumors are more common in overweight individuals, diabetics, patients with elevated serum cholesterol, and those suffering from familial multiple lipomatosis. Most of these tumors are treated for cosmetic reasons; however, large lipomas can also cause significant functional impairment. Traditional treatment includes surgical removal and / or liposuction. Deoxycholic acid is a member of the bile acid family that assists in the breakdown of fat. We investigated the use of deoxycholic acid injections to reduce the size of large lipomas prior to surgical removal. (more…)
Author Interviews, Autism, Cognitive Issues, JAMA / 04.01.2019

MedicalResearch.com Interview with: Tjasa Velikonja, PhD Department of Psychiatry The Seaver Autism Center for Research and Treatment Icahn School of Medicine at Mount Sinai New York, New York MedicalResearch.com: What is the background for this study? What are the main findings? Response: Autism is a lifelong condition, and challenges associated with autism persist from childhood into adulthood. Despite this, research and treatment have been largely dedicated to children. Because of that, we had very little understanding of what areas – what cognitive domains - are most severely impacted in adults with autism. Importantly, the lack of such information also limits treatment development in this area. What is known already is that adults with autism display deficits in social cognition (which refers to the role that cognitive processes play in our social interactions). Although our meta-analysis supported these theories, it also highlighted several other challenges in cognitive processing, such as deficits in processing speed and verbal learning and memory. And these impairments were observed in adults with autism without an overall intellectual disability. (more…)
Author Interviews, Health Care Systems, Ophthalmology / 07.11.2018

MedicalResearch.com Interview with: Nathan Radcliffe, MD Senior Faculty, Ophthalmology Glaucoma and Cataract surgeon Mount Sinai Health System MedicalResearch.com: What is the background for this study? Response: Glaucoma is a leading cause of blindness and the mainstay of therapy is to lower the intraocular pressure (IOP) with topical eye drops. Up to 40% of patients may require more than one eye drop to control the disease, and yet taking more than one eye drop bottle can result in higher costs, more eye irritation, worse therapeutic compliance, and possibly worse outcomes, be sure to consult your eye surgeon before increasing any eye treatment to ensure it won't do any further damage to the eye. Compounded therapies (not FDA approved, but made at the physician’s request by a compounding pharmacy) can be created to contain multiple glaucoma therapies in one bottle. We sought to determine if a compounded solution containing three or four drops in one bottle could control glaucoma as well as three or four separate bottles (standard of care) in patients requiring three or four eye drop bottles to control glaucoma. We performed a multi-center, randomized, observer-masked, parallel-group study comparing a compounded therapy containing latanoprost 0.05%, dorzolamide hydrochloride 2%, timolol maleate 0.5%, brimonidine tartrate 0.2% with 0.01% BAK to standard three or four bottle regaimins. We measured IOP and corneal staining (a sign of preservative toxicity), as well as other safety measures at week one, month one, two and three. (more…)
Author Interviews, Autism, JAMA, OBGYNE / 01.11.2018

MedicalResearch.com Interview with: Magdalena Janecka PhD Department of Psychiatry Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? Response: Our paper explored the association between maternal use of medication during pregnancy and the rates of autism in a large cohort from Israel. This followed on from a number of earlier studies reporting that the use of certain medications - for example antidepressants - during pregnancy is associated with higher rates of autism in children. However, rather than test the effects of any particular drug, or a set of drugs aggregated based on maternal condition, our large dataset allowed us to group all medications prescribed to pregnant women based on their drug target, and in the subsequent analyses focus on over 50 groups that included drugs with neurotransmitter-relevant targets - for example agonists and antagonists of their receptors.

Author Interviews, Dermatology, Environmental Risks / 15.10.2018

MedicalResearch.com Interview with: Dr. Janet Prystowsky, MD Dr. Prystowsky is a leading board-certified dermatologist in New York City.   In addition to her private practice, Dr. Prystowsky is a senior attending physician at Mount Sinai Roosevelt/St. Luke’s Medical Center. http://www.janetprystowskymd.com/ MedicalResearch.com: When does sun damage to the skin start?  Is there such a thing as a 'safe tan'?  Who is most susceptible to photoaging?  What parts of the body are more likely to show signs of sun damage?  Response: Sun damage will increase a person’s risk of premature aging and skin cancer.  Although tanning does function to help protect your skin from excessive ultraviolet radiation tanning is still a form of sun damage.  Also, people with very fair skin may not tan at all; only burn.  They are the most susceptible to sun damage. Certain medical conditions (e.g., Lupus), medications, cosmetics, and food can make your more reactive (photosensitive) to sunlight. "Sunburn" by Kelly Sue DeConnick is licensed under CC BY-SA 2.0Sunburns are caused by UV damage from sun rays, almost entirely due to UVB rays. UVA rays are weaker for burning but can contribute to blistering sunburns as well. For example, If you get lime peel rubbed on your skin while you are in the sun, you could get a bad burn.  UVA can also cause significant skin damage that can result in premature wrinkling, brown spots, and skin cancer. That's why you'll see dermatologists pushing for broad-spectrum sunscreens as opposed to sunscreens that just protect against UVB rays.  (more…)
