Author Interviews, Genetic Research, Leukemia, Personalized Medicine / 12.11.2024

MedicalResearch.com Interview with: Professor Ong Sin Tiong Cancer & Stem Cell Biology Signature Research Programme Duke-NUS Medical School, Singapore Dr Yu Mengge Research Fellow, Cancer & Stem Cell Biology Signature Research Programme Duke-NUS Medical School MedicalResearch.com: What is the background for this study? Response: The background of this study is rooted in the observation that certain genetic variations among East Asian populations, notably the BIM deletion polymorphism (BDP), impact treatment outcomes in chronic myeloid leukaemia (CML). Patients with the BDP show resistance to conventional treatments, specifically tyrosine kinase inhibitors like imatinib. This resistance stems from the variant's role in promoting cancer cell survival, which leads to more aggressive disease progression. (more…)

Author Interviews, Lyme / 08.11.2024

    Own a dog? Then your vet must have shared a thing or two about the risks of ticks and even warned you about Lyme disease.  But is your furry friend only at risk of this bacterial infection? You’re wrong if you think so. Humans can also get Lyme disease if a black-legged tick carrying the borrelia bacteria bites them. Just recently, the comedian and actress Miranda Hart opened up about how she struggled with chronic fatigue syndrome after she was diagnosed with Lyme disease.  Many other famous people say they have been struck by this tick-borne bacterial infection. Those include Real Housewives of Beverly Hills star Yolanda Hadid and her daughter, model Bella Hadid, comic Amy Schumer, actor Ben Stiller, and singer Justin Bieber.  As high-profile names share their struggles, awareness of Lyme is spreading fast. But so are the myths. So, let’s separate the facts from the fiction surrounding this disease.

Myth #1: Lyme Disease Is Only a Problem in the Northeast

The Northeast does see a lot of Lyme disease cases, and that is mainly because it has a high population of black-legged ticks. But it is not confined to New England.   Lyme-carrying ticks can be found across much of the United States, especially in the upper Midwest and along the West Coast. In 2022, the largest number of Lyme disease cases were reported in the Middle Atlantic region—New Jersey, Pennsylvania, and New York.  There has also been a rapid surge in the number of cases in the northern New England states of New Hampshire, Vermont, and Maine, reports Mount Sinai So, why the misconception? Part of it comes down to awareness—doctors in the Northeast are more used to spotting it, which can lead to better diagnosis rates. Meanwhile, in other areas, this bacterial infection might be misdiagnosed or underreported, which is why it flies under the radar.  (more…)
Author Interviews, Neurology, Sexual Health, STD / 06.11.2024

MedicalResearch.com Interview with: Sagar S. Patel, MBS Department of Medical Education Geisinger Commonwealth School of Medicine Scranton, PA 18509 MedicalResearch.com: What was the background for this research? Response: Syphilis is a sexually transmitted infection that is caused by a gram-negative bacterium called Treponema pallidum. This infection promotes the cell death of microglia and can cause a variety of symptoms. It is commonly observed in developing countries such as sub-Saharan Africa. Neurosyphilis is a complication of syphilis that affects the central nervous system (CNS). The CNS undergoes multiple stages of deterioration and can include personality changes and hearing abnormalities. Diagnosing neurosyphilis is challenging because its symptoms mimic other neurodegenerative diseases. Diagnosis relies on clinical studies, cerebrospinal fluid (CSF) analysis, and neuroimaging techniques. (more…)
AI and HealthCare, Author Interviews, Breast Cancer, Genetic Research / 06.11.2024

MedicalResearch.com Interview with: Prof. Dina Schneidman-Duhovny PhD Academic researcher Hebrew University of Jerusalem MedicalResearch.com: What is the background for this study? What are the main findings? Response: The study analyzed genetic data of 12 families (~ 40 patients) with high incidence of breast cancer cases. Most families originate from ethnic groups that are poorly represented in public resources. All participants were tested negative to all known breast cancer predisposing genes. We developed a novel approach to study genetic variants utilizing state-of-the-art deep learning models tailored for analysis of familial data. The study highlighted 80 high-risk genes (out of > 1200 genes) and narrowed down on a group of 8 genes circulating in 7 out of 12 families in the study. These genes are involved in a cellular organelle called the peroxisome and play a role in fatty acids metabolism. We show that  these genes significantly affect breast cancer survival and use 3-dimensional protein structural analysis to illustrate the effect of some of the variants on protein structure. These provide strong evidence of the peroxisome involvement in breast cancer predisposition and pathogenicity, and provide potential targets for patient screening and targeted therapies. (more…)
Author Interviews, Ovarian Cancer / 04.11.2024

MedicalResearch.com Interview with: Alessia Baccarini, PhD Assistant Professor Dept. of Immunology and Immunotherapy (DII) Icahn School of Medicine at Mount Sinai New York, New York 10029 MedicalResearch.com: What is the background for this study? Response: Ovarian cancer is characterized by a complex tumor microenvironment (TME) that significantly contributes to resistance against immunotherapy, particularly immune checkpoint blockade (ICB) therapies like anti-PD-1. Understanding the extracellular signals—such as cytokines and chemokines—that ovarian cancer cells utilize to create an immunosuppressive TME is critical for improving treatment outcomes. Our research focuses on elucidating how these signaling factors contribute to tumor growth and immune evasion. We utilized a novel genomic functional approach called Perturb-map to study intratumoral heterogeneity (ITH) in ovarian cancer within a mouse model, allowing us to investigate the communication between ovarian cancer cells and immune cells.  (more…)
Author Interviews, Cancer Research, Leukemia, Stem Cells / 01.11.2024

MedicalResearch.com Interview with: Eirini Papapetrou, MD, PhD Professor of Oncological Sciences Professor of Medicine, Hematology and Medical Oncology Director, Center for Advancement of Blood Cancer Therapies Co-Director, Stem Cell Engineering Core Icahn School of Medicine at Mount Sinai New York, NY 10029   MedicalResearch.com: What is the background for this study? What are the main findings? Response: RAS in the most commonly mutated oncogene in human cancers. Particularly in acute myeloid leukemia, about one third of cases have RAS mutations. We set out to understand the role of these mutations in the development of leukemia and in response to treatment. We found that RAS mutations happen late in the course of the disease as progression mutations because they are acquired by more mature leukemic cells coming from preexisting leukemia stem cells (LSCs). Importantly, these more mature cells, upon acquisition of RAS mutations, become leukemia stem cells (LSCs) with different properties than the previous LSCs. Most critically, they develop resistance to a recently FDA-approved drug for the treatment of leukemia, venetoclax (VEN). In addition, these RAS-mutated LSCs give rise to leukemia cells with monocytic differentiation. Both RAS mutations and monocytic differentiation of AML have previously been associated with VEN resistance in clinical studies. We show that it is the RAS mutations that cause both the monocytic differentiation and the VEN resistance. Thus, poor patient outcomes after VEN therapy are driven by RAS mutations and not by monocytic disease.  (more…)
Author Interviews, Health Care Systems, JAMA, Pharmacology, University of Pittsburgh / 31.10.2024

MedicalResearch.com Interview with: Katie J. Suda, PharmD, M.S., FCCP Professor of medicine with tenure Associate Director, Center for Pharmaceutical Policy and Prescribing University of Pittsburgh School of Medicine MedicalResearch.com: What is the background for this study? Response: Our pharmaceutical supply chain is global where the manufacturing process for one drug may occur in multiple countries. Sometimes there are breakdowns in the pharmaceutical supply chain which may threaten access to medicines. Breakdowns in the supply chain occur for medicines manufactured in the U.S. and by international partners. While breakdowns in the supply chain occur for hundreds of drugs each year, not all result in a decrease in available supply (a “drug shortage”) because of action taken by manufacturers, pharmacies and drug regulators (e.g., the U.S. Food and Drug Administration [FDA]). Drug shortages are a critical concern to public health as pharmacies, clinicians, and patients struggle to identify safe and effective alternatives. In addition, drug shortages have been associated with adverse patient outcomes and medication safety events. Recently, drug shortages have gotten worse with shortages occurring with increasing frequency and lasting longer. There has also been a shift in the types of medicines in shortage from drugs primarily used in hospitals, such as injectables, to oral medicines frequently used to manage outpatient conditions. Countries have different regulatory authority and policy which may impact how drug supply chain breakdowns result in drug shortages. We wanted to know if there are differences between the U.S. and Canada in the frequency that national drug shortages occur after supply chain breakdowns are reported in both countries. Canada is a good comparator to the U.S. because Canada has similar drug regulatory standards and manufacturing inspections. Prescription drug coverage is also similar for the two countries where half of prescriptions are reimbursed through public insurance and half through private insurance and out-of-pocket. (more…)
Author Interviews, Diabetes, Kidney Disease, Nature, Semaglutide / 31.10.2024

MedicalResearch.com Interview on publication of: Prof. dr. H.J. (Hiddo) Lambers Heerspink Clinical Pharmacologist Faculty of Medical Sciences University of Groningen MedicalResearch.com: What is the background for this study? What are the main findings? Response: The diabetes drug semaglutide, also known as Ozempic, has a positive effect for patients with chronic kidney damage and obesity. The amount of protein in their urine decreased, as did the degree of inflammation of their kidneys and their blood pressure. Hiddo L. Heerspink got the idea for this study at the beginning of the corona pandemic. Earlier, he had discovered that another class of drugs against diabetes-2, the so-called SGLT2 inhibitors also appeared to work well for patients with chronic kidney damage without diabetes. He therefore wanted to investigate whether semaglutide would also work positively for patients with chronic kidney disease and obesity. (more…)
Author Interviews, Mental Health Research, University of Michigan / 27.10.2024

MedicalResearch.com Interview with: Daniel J. Kruger, PhD University of Michigan MedicalResearch.com: What is the background for this study? Response: A team of researchers from the University of Michigan and University at Buffalo teamed up with psychedelic advocates and therapists to document some of the challenges with psychedelics. They surveyed over a thousand psychedelic users about their adverse experiences and the experiences they have heard from others. Most reported being frightened, sadness, loneliness, and feeling their body tremble or shake at times. Some people experienced panic, paranoia, felt that they are dead, or that the state they were in would last forever. One in ten participants had adverse physical reactions.  For most people having these experiences, they are rare or happen sometimes, but they are still significant. Most of the people that experienced a severe adverse event did not have guidance from someone who was knowledgeable about psychedelics. A small portion of participants knew about an incident of inappropriate sexual contact by a psychedelic sitter, guide, or practitioner, the perpetrators were mostly underground guides and friends or acquaintances.

Breast Reconstructive Surgery:

According to BreastCancer.org, the decision to have breast reconstructive surgery doesn’t have to be decided immediately following surgery to remove the breast. It can be done during mastectomy surgery or following surgery, so those who are uncertain about their decision have time to weigh the options before deciding on their best option. There are many things to consider breast reconstruction surgery, including the toll it will take on your body and how your appearance may change from before until after the surgery. Here are some things to consider if you have undergone a mastectomy. These are presented by Cancer.gov:
  • Breasts can be rebuilt using implants that contain either saline or silicone. They can also be rebuilt by using tissue elsewhere in the body.
  • The surgery can be done at the same time as the mastectomy (an immediate reconstruction) or after the surgery when the skin and incisions have had time to heal. Often, treatment is conducted during this healing time.
  • A nipple and areola can be added to the breast during the initial surgery or at a later time.

Addiction, Author Interviews / 20.10.2024

MedicalResearch.com Interview with: Karen Arscott, DO Department of Medical Education Geisinger Commonwealth School of Medicine Scranton PA 18509 MedicalResearch.com: What is the background for this study? Response: “Substance Use Disorder Risk Assessment (SUDRA)” is a proposed screening tool and possible source of prevention for substance use disorder (SUD) and alcohol use disorder (AUD).  The US opioid overdose epidemic continues to escalate with over one-hundred thousand deaths in a single year. The current screening tools used for assessing SUD identifies persons already suffering with advanced disease. Our investigation brings to light a simple screening tool which can be used to identify a person with “Preaddiciton” potential. For many years I have asked persons (both patients and nonpatients) the question how they felt the first time they took an opioid. Their answers have been astonishing. Probably the one answer that struck me the strongest was a professional colleague who answered that when she was prescribed Vicodin following a surgical procedure it made her feel so amazing that it scared her, and she never took another opioid. She reported to me that it would have been too easy to take regularly for the wonderful feeling – she however, recognized the danger of that feeling and avoided a potential substance use disorder. What if this risk was provided to all – what if parents and patients understood the risk if faced with that “feeling”? How many lives could be saved? We are very confident that these timely findings will be discussed and presented widely. The paper will be highly downloaded and cited by many interested in the prevention of substance use disorder – a new concept and much improved over the current treatment of advanced disease. (more…)

MedicalResearch.com Interview with: Eleni G. Jaswa, MD, MSc Assistant Professor, Ob/Gyn, Reproductive Science UCSF MedicalResearch.com: What is the background for this study? Response: Some infections during pregnancy have been associated with abnormal neurodevelopment in children. This is likely due to the infection itself, or the maternal immune system response to infection. We sought to determine whether maternal COVID-19 infection during pregnancy, a now common occurrence, was associated with changes in children's neurodevelopment out to 24-months-old, compared to control children not exposed to maternal COVID-19 in utero.

MedicalResearch.com Interview with: Frank F. Zhou   he/him MD Candidate, Class of 2025 David Geffen School of Medicine at UCLA MedicalResearch.com: What is the background for this study? What is Lecanemab used for?  How is it given to patients? Response: Lecanemab is a new infusion therapy for Alzheimer's disease. Its dosing is based on each patient's body weight (10 mg/kg every two weeks), but the drug is only available in 500 mg and 200 mg single-use vials, meaning that any leftover drug in vials must be thrown away. Given that lecanemab is expected to cost Medicare billions of dollars each year, we hypothesized that discarded drug could result in significant wasteful spending. (more…)

Editor's note: If you purchase semaglutide or similar medications, be sure to be followed by your health care provider and verify that the supplier is reputable before your purchases. When it comes to weight loss, it often feels like everyone has an opinion. Some swear by keto, while others say it's all about intermittent fasting. And let’s not forget the ever-popular crash diets that promise instant results but leave you feeling sluggish and starving. With so much conflicting advice, how can you figure out what actually works? This post attempts to break down the science behind weight loss, cutting through the noise and getting to the core of what really makes a difference in shedding those extra pounds—without the fads. weight-obesity-scale

Calories In, Calories Out: The Basics

At its most fundamental level, weight loss comes down to one basic principle: calories in versus calories out. The idea is simple—if you consume fewer calories than your body needs, you'll lose weight. This is known as creating a calorie deficit. Your body has to find energy somewhere, and when you're not giving it enough through food, it starts to use stored fat. However, it's not always as straightforward as it seems. People have different metabolic rates, meaning some burn calories faster than others. Plus, hormones, genetics, and lifestyle factors can all affect how easy or difficult it is to drop pounds. This is why two people on the same diet might experience different results. Key takeaway: To lose weight, you need to consistently eat fewer calories than you burn. But keep in mind that individual factors can influence how quickly (or slowly) this happens for you. (more…)
Aging, Author Interviews, BMJ, Heart Disease, Statins / 11.09.2024

MedicalResearch.com Interview with: Borislava Mihaylova, DPhil Associate Professor & Senior Health Economist Nuffield Department of Population Health, University of Oxford, UK & Professor of Health Economics Wolfson Institute of Population Health Queen Mary University of London, UK MedicalResearch.com: What is the background for this study? Response: Despite high risks of heart disease and stroke in people over 70 years old and high need for preventive treatment such as statins, fewer older people use statins [compared to middle-aged people]. This, at least in part, is likely due to fewer older people, particularly those without previous heart attacks and strokes, included in the randomized studies of statin treatment. This has led to more limited evidence among them with larger uncertainty. Thus, we set to re-examine the value of statin treatment using the latest evidence and contemporary population data. (more…)

Alzheimer's - Dementia, Author Interviews / 29.08.2024

stethoscope-alzheimers-article

Alzheimer’s disease is the most common condition that leads to a gradual loss of memory and thinking skills. It’s marked by the buildup of plaques and tangles in the brain. It’s one of many different areas where Anavex Life Sciences is focusing its research as part of its mission to develop effective therapeutics for neurodegenerative disorders. In 1984, researchers discovered that a protein called amyloid beta is a key part of the plaques that aggregate in the brain. This led to the theory that Aβ is central to Alzheimer’s, known as the "amyloid cascade hypothesis." Since then, most Alzheimer’s treatments have targeted Aβ. However, many of these treatments have failed in clinical trials, leading to questions about this approach. Aβ is created from a larger protein called amyloid precursor protein through a series of steps involving different enzymes. Normally, APP is processed in a way that prevents the formation of Aβ. However, under certain conditions, the enzymes BACE1 and γ-secretase cut APP in a way that produces Aβ. Once formed, Aβ needs to be cleared from the brain to prevent harmful buildup. Aβ clearance involves several pathways, including enzyme degradation, transport across the blood-brain barrier, and removal through the brain’s fluid drainage systems. The blood-brain barrier is a network of cells that controls what enters and leaves the brain. Specific proteins help move Aβ out of the brain, but for those with Alzheimer’s, these proteins don’t work as well, leading to Aβ accumulation. Genetic studies show that Aβ buildup plays a significant role in the disease. For example, people with Down syndrome, who have an extra copy of the APP gene, often develop Alzheimer’s. Mutations in genes related to APP processing can also cause early-onset Alzheimer’s, while certain mutations can protect against it. Both genetic and lifestyle factors, like diabetes and lack of exercise, can increase Aβ production or hinder its clearance. Despite setbacks, there are promising developments in Aβ-based therapies. Aducanumab, an antibody that targets Aβ, was approved by the FDA for its ability to reduce Aβ plaques in early Alzheimer’s patients. Another antibody, donanemab, has shown even better results in clearing Aβ from the brain. Similarly, lecanemab, which targets soluble forms of Aβ, has been shown to reduce amyloid levels and improve cognitive function. Another drug, Anavex 2-73 (blarcamesine), has shown potential in reducing Alzheimer’s symptoms and brain changes in animal studies and a late stage human trial. Blarcamesine is a formulation of Anavex, a clinical-stage biopharmaceutical company that develops therapeutics for the treatment of neurodegenerative and neurodevelopmental disorders including Alzheimer’s disease, Parkinson’s disease and other central nervous system disorders. These advances offer new hope that targeting Aβ could still be a valid approach to treating Alzheimer’s. (more…)
Author Interviews, Cognitive Issues, Environmental Risks, NIH, Pediatrics / 27.08.2024

MedicalResearch.com Interview with: Rick Woychik, Ph.D. Director of the National Toxicology Program Director of the National Institute of Environmental Health Sciences Principal Investigator Mammalian Genome Research Group Division for Intramural Research at NIEHS MedicalResearch.com: What is the background for this study? Response: Since 1945, the use of fluoride has been a successful public health initiative for reducing dental cavities and improving general oral health of adults and children. There is a concern, however, that some pregnant women and children may be getting more fluoride than they need because they now get fluoride from many sources including treated public water, water-added foods and beverages, teas, toothpaste, floss, and mouthwash, and the combined total intake of fluoride may exceed safe amounts.   Therefore, the National Toxicology Program (NTP) conducted a systematic review of the published scientific literature on the association between fluoride exposure and neurodevelopment and cognition. The NTP released their findings in a State of the Science Monograph on August 21, 2024, and posted to the NTP website. A corresponding meta-analysis on children’s IQ has been accepted by a scientific journal for publication later in 2024. The NTP started this work in 2016. As with all research documents intended for publication, the NTP fluoride monograph and meta-analysis underwent rigorous scientific evaluation.  The evaluation process has involved many steps. The draft fluoride monograph received significant critical feedback during peer-review by the National Academies of Science, Engineering and Medicine (NASEM), from other external experts, and from experts in several federal health agencies.  After modifications were made, additional evaluation following a rigorous scientific framework was conducted by subject matter experts organized by the NTP Board of Scientific Counselors. I am very pleased that this document is now complete and available for reference. Since fluoride is such an important topic to the public and to public health officials, it was imperative that we made every effort to get the science right. I commend the report authors, the NTP Board of Scientific Counselors, and countless subject matter experts who participated in this evaluation. The monograph represents a thorough review of the data, and the various interpretations of the data, to accurately reflect what we know and where additional research is needed.

Author Interviews, Autism, Brigham & Women's - Harvard, Genetic Research / 26.08.2024

MedicalResearch.com Interview with: Caroline Dias, M.D., Ph.D. Assistant Professor, Pediatrics-Developmental Pediatrics University of Colorado Anschutz Medical Campus       Christopher Walsh, M.D., Ph.D. Chief, Division of Genetics and Genomics Bullard Professor of Pediatrics and Neurology at Harvard Medical School and researcher who has used material donated to the brain bank     MedicalResearch.com: What is the background for this study? Response: Many different types of genetic variants contribute to neurodevelopmental disorders such as autism. Copy number variants are large pieces of genetic material that are duplicated or deleted. We have known for many years that many copy number variants at certain genetic locations are linked to autism. Because these copy number variants may include lots of different genes, it has been difficult to understand how these copy number variants alter human brain function. Furthermore, although animal models are important, autism is in many ways defined by differences in uniquely human cognitive and social functioning. Better understanding of how these copy number variants change human brain function will shed light on universal mechanisms that regulate neurodevelopment. We studied a copy number variant called dup15q, that is associated with almost 40-fold higher rates of autism vs. the general population. We studied post-mortem human brain tissue from individuals with dup15q, individuals with autism not related to dup15q, and neurotypical controls, to better understand how the human brain is impacted by dup15q. We focused on frontal cortex, an important brain region in executive function and social perspective taking. We applied cutting edge techniques that allow us to assess individual cells in the brain.  (more…)
