Alzheimer's - Dementia, Author Interviews, Biomarkers / 11.12.2024

MedicalResearch.com Interview with: Alberto J. Espay, MD, MSc, FAAN Professor of Neurology Director and Endowed Chair Gardner Family Center for Parkinson's disease and Movement Disorders University of Cincinnati Academic Health Center MedicalResearch.com: What is the background for this study? What are the main findings Response:  Because aducanumab, lecanemab, and donanemab were only in a minority of anti-amyloid treatments showing a benefit, I was interested in finding out what makes them special. It turns out that they not only clean the brain from amyloid, like other monoclonal anti-Aβ antibodies, but they also increase Aβ42 in the spinal fluid, which is a measure of the normal protein in the brain. Everyone with Alzheimer’s has low Aβ42 levels because this protein clumps into amyloid plaques. I tested the hypothesis that increasing Aβ42 could explain the cognitive outcomes at least as well as decreasing amyloid, and that’s exactly what we found. This suggests that restoring the normal protein levels, Aβ42, may explain why some anti-amyloid treatments (presumably those that increased those levels the most) come with benefits. (more…)

MedicalResearch.com Interview with: Miriam A. Bredella, MD, MBA Bernard and Irene Schwartz Professor of Radiology & Vice Chair for Strategy Associate Dean for Translational Science Director, Clinical and Translational Science Institute NYU Grossman School of Medicine NYU Langone Health Translational Research Building 743 New York, NY 10016   MedicalResearch.com: What is the background for this study? Response: We perform >80 million CTs every year in the US, and there is a lot of information on these CTs that is not used and “thrown away.” Opportunistic imaging or opportunistic screening with the help of AI takes advantage of this information and automatically detects and quantifies vascular calcification, bone mineral density, abdominal fat or muscle mass. In our study, we wanted to detect whether calcification of the abdominal aorta, quantified using AI, could predict coronary artery calcification and major cardiovascular events (e.g. myocardial infarction, cardiac revascularization, stroke, or death).

Author Interviews, Cancer Research, NEJM, NIH, OBGYNE / 05.12.2024

MedicalResearch.com Interview with: Diana W. Bianchi, M.D. Senior Investigator Center for Precision Health Research Director, Eunice Kennedy Shriver National Institute of Child Health and Human Development National Institutes of Health MedicalResearch.com: What is the background for this study? Response: The ability of prenatal cell-free DNA (cfDNA) sequencing to incidentally detect maternal cancers has been demonstrated by several retrospective studies from commercial or national laboratories. However, there are no standardized approaches to the identification and medical management of prenatal screening results that might indicate a maternal cancer. We sought to prospectively identify DNA sequencing patterns and other biomarkers that could distinguish which women with nonreportable or unusual cfDNA sequencing results had cancer and to determine the best approach for diagnostic work-up of pregnant people who receive these results.

MedicalResearch.com Interview with: John W. AyersJohn W. Ayers, PhD, MA Altman Clinical Translational Research Institute University of California San Diego, La Jolla MedicalResearch.com: What is the background for this study? Response: Crisis pregnancy centers (CPCs) are frequently at the center of news and policy debates, yet little data exists about where they operate or what they actually do. To address this gap, we developed ChoiceWatch.org, a tool that systematically collected and analyzed over 470,000 webpages from CPC websites. In our study published in JAMA Internal Medicine, we used ChoiceWatch.org, to answer fundamental questions, such as how many crisis pregnancy centers operate in the U.S., where they are located, and what services they advertise.

Author Interviews, COVID -19 Coronavirus, Mental Health Research, Pulmonary Disease / 30.11.2024

MedicalResearch.com Interview with: Sean B. Fain, Ph.D. Professor and Vice Chair for Research Department of Radiology Affiliate Appointments BME and ECE University of Iowa Iowa City, IA MedicalResearch.com: What is the background for this study? Response: This study uses MRI to investigate connections between lung and brain function. We employ an advanced MRI technique that uses hyperpolarized xenon gas as a contrast agent. This approach allows us to image which parts of the lung are effectively inhaling xenon gas and which parts are not (i.e. ventilation). Additionally, xenon provides insights into lung gas exchange (i.e. oxygen transfer into and out of the blood), as it freely diffuses into alveolar tissue and binds to red blood cells. Using this technology, we hypothesized that the severity of lung injury in individuals with Long COVID would correlate with the degree of cognitive dysfunction and brain imaging. (more…)

Author Interviews, Protein, Weight Research / 28.11.2024

    Protein is a fundamental nutrient that plays a vital role in weight loss and appetite regulation. Understanding how protein affects these areas can help optimize dietary strategies for better health outcomes. From influencing hunger hormones to boosting metabolism, protein’s role in the body is multifaceted and powerful.

How Protein Influences Appetite

One of protein’s standout benefits is its ability to enhance feelings of fullness, also known as satiety. When you consume protein-rich foods, your body releases appetite-suppressing hormones such as peptide YY and GLP-1, which signal your brain to reduce hunger. In contrast, diets low in protein may leave individuals feeling hungrier, leading to overeating or increased snacking. This is why many weight loss programs emphasize incorporating high-protein meals and snacks to curb cravings and improve adherence to calorie-controlled plans. (more…)

Anterior Cervical Discectomy Surgery While anterior cervical discectomy surgery has become a widely accepted and frequently performed procedure to relieve spinal cord or nerve root compression, it is not without potential risks and complications. These can range from common surgical risks, such as infection, to more procedure-specific complications like nerve damage, dural tears, and the possibility of recurrent disc herniation. As there is a critical need for increased awareness and understanding of these challenges, it is essential to engage in a thorough exploration of the potential outcomes and their management tactics.

Understanding Anterior Cervical Discectomy

The anterior cervical discectomy is a surgical procedure that warrants comprehension due to its complex nature. This surgical technique involves the removal of an intervertebral disc or a portion of this disc from the neck area, specifically in the anterior cervical spine. It is typically performed to alleviate spinal cord or nerve root pressure, leading to considerable pain relief and functional improvement. The procedure is often paired with a fusion to stabilize the spine. The recovery timeline varies for each individual depending upon factors like age, overall health status, and the severity of the disc problem. However, the immediate postoperative recovery period typically lasts for a few hours to a few days, during which time patients are closely monitored. Subsequent recovery, involving physical therapy and gradual return to normal activities, can stretch from several weeks to a few months. Though the anterior cervical discectomy is generally regarded as a safe and effective procedure, it is not devoid of risks. Potential complications include infection, nerve damage, difficulties swallowing or speaking, and issues related to the graft or hardware used in fusion. The understanding of these risks is paramount for patients undergoing this procedure. (more…)

MedicalResearch.com Interview with: Belén Blasco PhD Student in Neuroscience - MD Psychiatry Clinical and Translational Sciences (CaTS) Lab Integrated Program in Neuroscience McGill University | Douglas Research Centre Montreal, Canada MedicalResearch.com: What is the background for this study? Response: Our research is centered on uncovering the early brain changes that might contribute to psychosis development. Using innovative brain imaging techniques, we aimed to measure synapsis in individuals with early psychotic symptoms or who are considered at high clinical risk. Synapses are the crucial points of connection between neurons, allowing communication across the brain. A key aspect of our study was to understand how lifestyle factors, like cannabis use, might impact these brain changes, particularly since cannabis consumption has been associated with an increased risk of developing psychosis in young people.

Discussion and Explanation of Minimally Invasive Spine Surgery by: Brent A. Felix, M.D Spine Surgery, Bone & Joint Surgery Salt Lake Orthopaedic Clinic Suite 4050 Salt Lake City, UT 84124 and Alpine Orthopaedic Specialists North Logan, UT 8434  

Minimally invasive spine surgery (MISS) has become a game changer in orthopedic surgery, offering patients safer and less painful options for treating spinal issues. Dr. Brent Felix, a leading orthopedic spine surgeon, is at the forefront of this movement, advocating for these innovative techniques that provide multiple benefits over traditional methods.

What Is Minimally Invasive Spine Surgery?

Minimally invasive spine surgery, or MISS, is a technique that allows surgeons to address spine conditions with much smaller incisions compared to traditional surgery. Rather than making large cuts to access the spine, Dr. Felix and his team use special instruments and imaging tools to perform surgery through small incisions. These tools include tiny cameras or endoscopes, which provide a clear view of the spine without the need for large openings.

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.

Author Interviews, Emergency Care / 26.10.2024

Whether preparing for emergencies or stocking a medical facility, having the right medical supplies can mean the difference between life and death. What are the most needed medical supplies? First aid kits, bandages, antiseptics, pain relievers, prescription medications, and personal protective equipment (PPE) are the most essential medical supplies. These items account for over 80% of basic medical needs in emergency and routine situations.   While this list covers the basics, it's important to keep reading because the specific medical supplies you need can vary significantly based on your situation – whether you're stocking a home first aid kit, preparing for a natural disaster, or equipping a medical facility. Understanding these scenarios will help you make better-informed decisions about which supplies to prioritize. (more…)

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.

Alzheimer's - Dementia, Author Interviews, Cost of Health Care, Medicare, UCLA / 15.10.2024

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…)
