Author Interviews, Cancer Research, JAMA, Weight Research / 02.11.2025

MedicalResearch.com Interview with: Jiang Bian, PhD Associate Dean of Data Science Walther and Regenstrief Professor of Cancer Informatics Professor of Biostatistics & Health Data Science Adjunct Professor, Biomedical Engineering and Informatics Chief Data Scientist, Regenstrief Institute Chief Data ScientistCustomize & Schedule Social Media Posts Indiana University Health Serena Jingchuan Guo, MD PhD Assistant Professor Department of Pharmaceutical Outcomes and Policy University of Florida College of Pharmacy Hao Dai, PhD Postdoctoral Fellow Department of Biostatistics & Health Data Science Indiana University School of Medicine       MedicalResearch.com: What is the background for this study? What are the main findings? Response: Obesity and type 2 diabetes are both known to increase the risk of several cancers. Glucagon-like peptide 1 receptor agonists (GLP-1RAs) have become very popular for both glycemic control and weight loss, but their long-term effects on cancer risk are still unclear. Using a large real-world dataset, we emulated a target trial comparing more than 43,000 GLP-1RA users to matched non-users. We found that GLP-1RA use was associated with a significantly lower overall cancer risk. (more…)
Author Interviews, Cancer Research, Dental Research, JAMA, Microbiome, NYU, Pancreatic / 13.10.2025

MedicalResearch.com Interview with: Jiyoung Ahn, PhD Professor of Population Health, NYU Grossman School of Medicine Associate Director for Population Science, NYU Perlmutter Cancer Center NYU Langone Health New York, NY 10016 MedicalResearch.com: What is the background for this study? Response: About 10 years ago. we reported that people with poor oral health seem to have a greater risk of pancreatic cancer development.  We suspected that this could be due to oral microbiota.  More recently, animal studies, by other groups, showed that bacteria from the mouth can actually travel through saliva into the pancreas. But we didn’t know which exact species of bacteria or fungi might be involved in pancreas cancer development. We therefore conducted this large human study to examine the oral microbiome — including whole bacteria and fungi profiles in the mouth, and to see which bacteria and fungal taxa are associated with subsequent risk of pancreatic cancer development.

Author Interviews, Dermatology, Hair Care, JAMA / 11.10.2025

Brett King, MD, PHD  Dr. King was named an American Academy of Dermatology (AAD) “Patient Care Hero” for his work treating patients with severe alopecia areata Dermatology Physicians of Connecticut Fairfield, Connecticut MedicalResearch.com: What is the background for this study? Would you briefly explain the condition of Alopecia Areata? Response: Alopecia Areata (AA), an autoimmune form of hair loss, is common and its treatment has been revolutionized in the past ~3 years with approvals of 3 JAK inhibitors, bariticinib, ritlecitinib and deuruxolitinib. Prior to these approvals, off label treatments included the JAK inhibitors tofacitinib and ruxolitinib.   In a world of multiple treatments, especially when those treatments belong to the same medicine class, the question arises “If patients do not achieve treatment success with one medicine, might they achieve treatment success with another one?” (more…)
Author Interviews, Autism, Brigham & Women's - Harvard, JAMA / 06.10.2025

Memantine to Treat Social Impairment in Youths With ASD

MedicalResearch.com Interview with: Gagan Joshi, MD Director, The Alan & Lorraine Bressler Clinical and Research Program for Autism Spectrum Disorder Associate Director, The Pediatric Psychopharmacology Research Program Associate Program Director, MGH Fellowship in Autism Spectrum Disorder Rovee Endowed Chair in Child Psychiatry Massachusetts General Hospital Associate Professor of Psychiatry Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Intellectually capable individuals with autism often face significant challenges in social functioning, yet pharmacologic treatments specifically targeting social impairments are lacking. Our prior neuroimaging research identified abnormally elevated brain glutamate levels in intellectually capable youth with autism, suggesting a potential neurochemical pathway underlying social difficulties. Based on these findings, we examined the effects of memantine—a glutamate-modulating medication—for the treatment of autism. (more…)
Author Interviews, Cancer Research, Dermatology, JAMA / 06.10.2025

MedicalResearch.com Interview with: Lee Wheless, MD, PhD Assistant Professor Department of Dermatology Department of Medicine, Division of Epidemiology Vanderbilt University Medical Center Staff Physician Tennessee Valley Health System VA Medical Center MedicalResearch.com: What is the background for this study? Response: Nicotinamide has been in use for skin cancer prevention for at least a decade. A more recent trial among solid organ transplant recipients (SOTR) specifically concluded that there was no benefit in this population. While that study had a number of issues, it really led dermatologists to question whether it was efficacious. This coupled with another study around the same time that suggested that metabolites of nicotinamide might increase the risk of major adverse cardiovascular events (MACE). My group earlier this year conducted a similar study to this one showing that we really did not observe any increase in MACE at the population level. We then turned to address of the question of if nicotinamide was actually useful in reducing skin cancer risk. (more…)
Anemia, Author Interviews, Hematology, JAMA, Pain Research, Pediatrics / 03.09.2025

MedicalResearch.com Interview with: Ibrahim Gwarzo, DrPH, MPH, MBBS Research Scientist at Nemours Children’s Health Delaware Valley, Delaware USA MedicalResearch.com: What is the background for this study? Would you briefly explain the condition of sickle cell disease and why young people frequently present to the ER with severe pain? Response: Sickle cell disease is an inherited blood disorder that affects red blood cells. It is passed down as an autosomal recessive disorder, meaning a person must inherit the defective gene from both parents to have the disease. The condition primarily impacts hemoglobin, the protein responsible for carrying oxygen in red blood cells, which leads to changes in the shape and stability of these cells. The complications associated with the disease, including recurrent and severe pain episodes, are a direct result of these changes. These pain episodes are debilitating and unpredictable, resulting in frequent emergency department visits where they are typically treated with pain medications, including opioids. It is estimated that around 100,000 people in the United States have sickle cell disease, with about 40,000 being children. The disease has a significant prevalence in the Afro-Latino population.

Author Interviews, Geriatrics, JAMA, Pharmacology / 05.08.2025

MedicalResearch.com Interview with: Emily G. McDonald MD MSc (Epi) FRCPC Scientist | Research Institute of the McGill University Health Centre Associate Professor of Medicine | General Internal Medicine | McGill University Health Centre Associate Chair of Quality and Safety | Department of Medicine | McGill University Director | Canadian Medication Appropriateness and Deprescribing Network Centre for Outcomes Research and Evaluation (CORE) Montreal, QC https://www.medsafer.org/ https://www.deprescribingnetwork.ca/   MedicalResearch.com: What is the background for this study? What are the main findings? Response: Polypharmacy (taking multiple medications) is common among older adults and can lead to serious side effects like memory problems, falls, fractures, and hospitalization. Deprescribing (the process of stopping some medications that may no longer be beneficial or where the harms outweigh the benefits) is a great solution. This study found that an electronic tool to support prescribers increased deprescribing more than 3 times compared to usual care without the software support. (more…)
Accidents & Violence, Author Interviews, JAMA, USPSTF / 12.07.2025

MedicalResearch.com Interview with: Dr. David Chelmow, M.D. Leo J. Dunn professor of obstetrics and Chair of the Department of Obstetrics-Gynecology Virginia Commonwealth University (VCU) School of Medicine Richmond, Virginia Dr. Chelmow joined the U.S. Preventive Services Task Force in January 2022 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Intimate partner violence, also known as domestic violence, affects millions of people in the United States and can have devastating consequences for one’s health and wellbeing. Clinicians can make a real difference for those affected—evidence shows that there are screening tools that can detect intimate partner violence in women, including those who are pregnant, as well as interventions that work to reduce future violence. As a result, the Task Force recommends that clinicians screen all women of reproductive age, including those who are pregnant and postpartum, for intimate partner violence and refer those who screen positive to ongoing services so they can get the care they need to stay safe. The Task Force also recognizes that caregiver abuse of older and vulnerable adults is an important issue. Unfortunately, right now there is not enough evidence to recommend for or against screening for caregiver abuse and neglect of older and vulnerable adults, so we are calling for more research in these important areas. (more…)
Author Interviews, JAMA, Osteoporosis, USPSTF / 24.06.2025

MedicalResearch.com Interview with: Esa M. Davis, M.D., M.P.H. Vice chair, USPSTF Professor of Family and Community Medicine Senior Associate Dean of Population and Community Medicine University of Maryland School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Osteoporosis causes bones to become weak and break or fracture more easily. It is more common as people age and can lead to serious disability, chronic pain, loss of independence, and even death. The Task Force looked at the evidence and found that all women who are 65 and older should be screened for osteoporosis. Menopause causes hormone changes that affect a person's bone density and causes their bones to break down faster than they can rebuild, thereby increasing a person's risk of osteoporosis. As a result, women younger than 65 who have already gone through menopause and have at least one additional risk factor for osteoporosis should receive a formal risk assessment to determine whether they should then be screened. It's important to note that men can also get osteoporosis and have similar risk factors as women, but unfortunately there is not enough evidence to determine whether or not screening and then treating men can help prevent fractures.

Author Interviews, Cognitive Issues, JAMA, OBGYNE, Pediatrics / 15.04.2025

MedicalResearch.com Interview with: Samson Nivins PhD Post-doc | Neonatology Karolinska Institutet Developmental Neuroscientist Liggins Institute   Ulrika Ådén PhD Professor of Neonatology Department of Women's and Children's Health Karolinska     MedicalResearch.com: What is the background for this study? Response: Children born preterm are at higher risk of cognitive impairment during childhood and later in life. However, an important unresolved question is whether these impairments primarily reflect genetic susceptibility or are driven by the biological consequences of being born too early. Cognitive development is known to have a strong heritable component (~70 %), and previous studies have attempted to disentangle genetic and environmental contributions, for example through sibling comparison designs. Although informative, such approaches have inherent limitations. In this study, we aimed to investigate long-term cognitive outcomes across a range of gestational age groups including very preterm, moderately preterm, late preterm, and early term, compared to children born full term. Importantly, we accounted for genetic influences as well as a range of potential confounding factors, including prenatal risks and child-specific factors. This approach provides a more nuanced understanding of the extent to which cognitive outcomes associated with preterm birth reflect biological versus inherited risk. (more…)
Alzheimer's - Dementia, Author Interviews, Diabetes, JAMA, Weight Research / 09.04.2025

MedicalResearch.com Interview with: Dr. Catriona Reddin MD Fourth year Specialist Registrar in Geriatric Medicine  and an Irish Clinical Academic Training (ICAT) fellow University Hospital Galway, Galway, Ireland   MedicalResearch.com: What is the background for this study? Response: Dementia is a leading cause of disability globally, which is projected to affect approximately 75 million people by 2030. Diabetes mellitus is a risk factor for dementia, it was unclear if glucose lower therapies reduce the risk of dementia. The research, a systematic review and meta-analysis of 26 clinical trials involving over 160,000 participants, found that while most glucose-lowering therapies were not significantly associated with a reduction in dementia risk, one class of drugs—GLP-1Ras—was linked to a significant reduction.

Author Interviews, Gender Differences, JAMA, University of Michigan / 14.02.2025

MedicalResearch.com Interview with: Farrah Madanay, PhD Postdoctoral Research Fellow Center for Bioethics and Social Sciences in Medicine Michigan Medicine University of Michigan MedicalResearch.com: What is the background for this study? Response: Patients are increasingly using online forums to evaluate their physicians, with not only star ratings but also written narrative reviews. These reviews tend to fall into two dimensions: interpersonal manner, which includes comments about the physician’s attitude, behavior, and communication; and technical competence, which includes comments about the physician’s knowledge, skill, and outcomes. These two dimensions are important for patient-centered care and align with research from social psychology. Whereas prior studies have revealed gender differences in workplace assessments and overall star ratings of physicians, little is known about physician gender differences in patients’ online written reviews. We were curious whether physician gender differences were prevalent in patients’ written reviews and consistent across physician specialties, from generalists, like primary care physicians, to proceduralists, like surgeons. We collected physician profile, rating, and review data from one of the largest commercial physician rating and review websites. We focused on physicians from three primary care specialties (family medicine, internal medicine, and pediatrics), and three surgical specialties (general surgery; orthopedic surgery; and cosmetic, plastic, and reconstructive surgery). Our final sample included 345,053 online reviews received by 167,150 U.S. physicians between 2015 and 2020. We used hand-coded reviews to train an advanced natural language processing algorithm to classify all reviews for the presence and valence of patients’ comments of physicians’ interpersonal manner and technical competence. We then conducted multilevel logistic regressions to analyze differences by female or male physician gender in interpersonal manner and technical competence comments and whether those comments were associated with review star ratings.

Author Interviews, JAMA, Salt-Sodium, Stroke / 09.02.2025

MedicalResearch.com Interview with: Xiong Ding, MPH School of Public Health Wuhan University Wuhan, China MedicalResearch.com: What is the background for this study? Response: Stroke is one of the leading causes of death and long-term disability worldwide, particularly in low- and middle-income countries. Patients who have previously experienced a stroke are at high risk of recurrence, and in China, this risk is even higher than the global average. It is well established that high blood pressure is a major risk factor for stroke recurrence, and lowering blood pressure is an effective preventive strategy. Salt substitutes, which replace part of sodium chloride with potassium chloride, have been shown to lower blood pressure by reducing sodium intake and increasing potassium intake. However, before our study, there was limited direct evidence demonstrating whether salt substitutes could reduce the risk of stroke recurrence and death. Therefore, we conducted this research as part of the Salt Substitute and Stroke Study (SSaSS), specifically focusing on stroke survivors to determine the long-term health effects of salt substitution in this high-risk population.

Author Interviews, Cannabis, JAMA, Pediatrics, UCSD / 30.01.2025

MedicalResearch.com Interview with: John Bellettiere, PhD Assistant Adjunct Professor Herbert Wertheim School of Public Health & Human Longevity Science University of California, San Diego MedicalResearch.com: What is the background for this study? Response:  Smoking is the most common method of cannabis use and generates harmful emissions.  Cannabis is often smoked indoors, which exposes non-smokers, including children, to these emissions. Our research analyzed in-home cannabis smoking practices to determine if there is an association between this behavior and the detection of cannabis biomarkers in children. (more…)
Author Interviews, Cannabis, Cognitive Issues, JAMA, Memory, Mental Health Research / 28.01.2025

MedicalResearch.com Interview with: Joshua Gowin PhD Assistant Professor, Radiology Anschutz Medical Campus University of Colorado  MedicalResearch.com: What is the background for this study? Response: Many people want to know how cannabis affects their brain and cognitive abilities. Previous studies have shown that cannabis use can impair learning and verbal memory function. Some evidence has shown that cannabis use is associated with smaller volume of areas of the prefrontal cortex. Our study investigated how cannabis use is associated with brain function. We examined brain function across 7 tasks in 1,000 adults. 88 of them had used cannabis over 1,000 times in their lives. (more…)
Author Interviews, Cannabis, JAMA / 25.01.2025

MedicalResearch.com Interview with: Silvia S. Martins, MD, PhD Associate Dean for Faculty Professor of Epidemiology Director, Substance Use Epidemiology Unit Co-Director, Substance Abuse Epidemiology T32 Program Department of Epidemiology Columbia University Mailman School of Public Health New York, NY MedicalResearch.com: What is the background for this study? Response: Much has been speculated on whether the enactment of medical and recreational cannabis laws can have a role in decreasing prescriptions for opioid pain relievers, opioid use and misuse, opioid use disorder, and overdose in the U.S. However, findings on the associations of medical cannabis laws alone and recreational cannabis las + medical cannabis laws with opioid-related outcomes are mixed. By the end of 2019, 32 U.S. states had adopted medical marijuana laws (MCL) alone. All states that went on to adopt recreational marijuana laws (RCL) had previously adopted an MCL. (more…)
Author Interviews, Cannabis, JAMA, Mental Health Research / 22.11.2024

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. (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, COVID -19 Coronavirus, JAMA, OBGYNE, Pediatrics / 16.10.2024

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. (more…)
Author Interviews, JAMA, Pharmaceutical Companies / 11.10.2024

MedicalResearch.com Interview with:

David-Dan Nguyen MDCM MPH Doctoral Student Institute of Health Policy Management and Evaluation and Resident Physician Division of Urology University of Toronto

MedicalResearch.com: What is the background for this study? Response: Peer reviewers are crucial to the academic publishing process. While there’s been significant scrutiny of potential conflicts of interest among authors and editors of major journals, the potential for conflicts of interest among peer reviewers has been relatively unexplored. As such, our study aimed to quantify and characterize industry payments made to peer reviewers of top medical journals—The BMJ, JAMA, The Lancet, and The New England Journal of Medicine—to better understand the extent of these financial relationships.  (more…)
Author Interviews, Cancer Research, JAMA, Microbiome, NYU / 01.10.2024

MedicalResearch.com Interview with: Jiyoung Ahn, PhD Professor of Population Health, NYU Grossman School of Medicine Associate Director for Population Science, NYU Perlmutter Cancer Center NYU Langone Health Smilow Research Building New York, NY 10016 MedicalResearch.com: What is the background for this study? What are the main findings? Response: We found that oral bacterial species are linked to a collective 50% increased risk of developing head and neck squamous cell carcinoma (HNSCC). Some of these microbes have previously been shown to contribute to periodontal disease, a serious gum infection that can erode the jawbone and the soft tissues surrounding the teeth. (more…)
Anemia, Author Interviews, JAMA, OBGYNE / 23.08.2024

Esa M. Davis, M.D., M.P.H , F.A.A.F.P Professor of Medicine and Family and Community Medicine Associate Vice President of Community Health and Senior Associate Dean of pPopulation Health and Community Medicine University of Maryland School of Medicine Dr. Davis joined the U.S. Preventive Services Task Force in January 2021     MedicalResearch.com: What is the background for this study? What are the main findings? Response: Iron is important to overall health, and people need more iron when they are pregnant. This can make pregnant people at increased risk for iron deficiency, which can progress to anemia and cause complications for both moms and their babies. After reviewing the latest available research, the Task Force found that there is not enough evidence on whether pregnant people who do not have signs or symptoms of iron deficiency or anemia should be screened—or take iron supplements—to improve their health or the health of their baby.   (more…)
Author Interviews, Brigham & Women's - Harvard, Genetic Research, JAMA, Karolinski Institute, Prostate Cancer / 05.07.2024

MedicalResearch.com Interview with: Anna Plym PhD Department of Medical Epidemiology and Biostatistics, Karolinska Institutet, Stockholm, Sweden Department of Epidemiology, Harvard T. H. Chan School of Public Health Department of Urology, Brigham and Women’s Hospital Harvard Medical School, Boston, Massachusetts MedicalResearch.com: What is the background for this study? Response: Prostate cancer is one of the leading causes of cancer death among men, with approximately one third of the deaths occurring before the age of 75 years. There is a need for a better understanding of the risk factors for those early deaths. Our previous research has indicated that inherited factors play a major role. (more…)
Author Interviews, Heart Disease, JAMA, Lipids / 03.07.2024

MedicalResearch.com Interview with: Evan A Stein MD PhD FACC COO/CSO LIB Therapeutics Cincinnati. OH USA 45227 MedicalResearch.com: What is the background for this study? Response: Cardiovascular disease (CVD) remains the main cause of morbidity and mortality worldwide and is increasing in rapidly industrializing countries and is projected to cause more than >20 million deaths annually over the next 15 years. Low-density lipoprotein cholesterol (LDL-C) is well established as a major, easily modifiable, risk factor for CVD. Reductions with statins and, more recently, PCSK9 inhibitors, all agents which directly or indirectly upregulate the LDL receptor and enhance LDL-C clearance, have demonstrated CVD event reductions in cardiovascular outcome trials. Extensive data from these trials, provide a rough estimate that every 40 mg/dL reduction in LDL-C will reduce the risk of major CV cardiovascular events by 22% to 24%. Furthermore, trials with PCSK9 inhibitors added to statins which achieve substantial additional LDL-C reduction show and CVD event reduction remains linear to very low LDL-C levels without signals of adverse events. Based on this body of evidence, recent revisions to national and international guidelines, now advocate for greater LDL-C reductions and lower LDL-C treatment goals, for patients not achieving these goals on statins alone. The current consensus target goal for LDL-C in patients with CVD, or who are at very-high risk for of CVD, is now less than <55 mg/dL, and <70 mg/dL for those at high risk. This global trial of over 900 patients with CVD, or at very or high risk for CVD, on maximally tolerated statins assessed the 52-week efficacy and safety of monthly lerodalcibep. (more…)
Author Interviews, Cost of Health Care, JAMA, Kidney Disease, Transplantation / 01.07.2024

MedicalResearch.com Interview with: Amal Trivedi, MD, MPH Professor of Health Services, Policy & Practice Brown University School of Public Health MedicalResearch.com: What is the background for this study? Response: On January 1st, 2021, the Centers for Medicare & Medicaid Services (CMS) launched the mandatory End-Stage Renal Disease Treatment Choices (ETC) Model, which randomly assigned approximately 30% of U.S. dialysis facilities and managing clinicians to financial incentives to increase the use of home dialysis and kidney transplantation. The program is set to run through 2027, with financial incentives and penalties increasing as the model progresses. Our study sought to assess the ETC’s effect on these outcomes of interest in the first two years, as well as to examine outcome changes by race, ethnicity and socioeconomic status. (more…)
Alzheimer's - Dementia, Author Interviews, JAMA / 22.06.2024

MedicalResearch.com Interview with: Mabel Seto, PhD Harvard Aging Brain Study, Department of Neurology Massachusetts General Hospital, Center for Alzheimer Research and Treatment Department of Neurology Brigham and Women’s Hospital Harvard Medical School, Boston, Massachusetts Vanderbilt Memory and Alzheimer’s Center Vanderbilt University Medical Center Nashville, Tennessee   MedicalResearch.com: What is the background for this study? Response: The background for this study is that individuals with a family history of Alzheimer’s disease (i.e., one or more first-degree relatives) have a higher risk for the disease than individuals that don’t have a family history. Previous studies suggested a preferential maternal inheritance of AD, though they were limited in sample size and statistical power. In our study, we wanted to focus on a larger, cognitively unimpaired sample. Using data from the Anti-Amyloid Treatment in Asymptomatic Alzheimer’s (A4) study, a randomized clinical trial aimed at AD prevention, we examined the relationship between a parental history of significant memory impairment as a proxy for AD (as some individuals may not have pursued formal diagnosis) and amyloid-beta burden in the offspring. (more…)
Author Interviews, Breast Cancer, Colon Cancer, Genetic Research, JAMA / 20.06.2024

MedicalResearch.com Interview with: Dr. Jeremy L. Davis M.D. Surgical Oncologist Center for Cancer Research Dr. Davis’ research focuses on sporadic and inherited forms of stomach cancer. National Cancer Institute   MedicalResearch.com: What is the background for this study? Response: Individuals who are born with a CDH1 gene mutation are at increased risk of developing specific cancers in their lifetime. Those cancers are called diffuse-type gastric cancer and lobular breast cancer. The background that is relevant here is that when mutations in this gene were first identified as the cause of inherited forms of these cancers, the estimated lifetime risk of gastric cancer, for instance, was around 60-83%. Because of this very high risk and because gastric cancer is particularly difficult to treat, many experts recommend prophylactic surgery to remove the stomach. In recent years, as we have seen more families who carry a CDH1 gene mutation, we have also observed that gastric cancer rates did not seem quite as high as those risk estimates would have suggested. We sought to re-evaluate lifetime risk of cancer with a large and diverse cohort of individuals throughout North America. (more…)
Author Interviews, Dermatology, JAMA, Salt-Sodium / 12.06.2024

MedicalResearch.com Interview with: Katrina Abuabara, MD, MA, MSCE Associate Professor of Dermatology, UCSF Associate Adjunct Professor of Epidemiology UC Berkeley School of Public Health MedicalResearch.com: What is the background for this study? Response: Eczema (also known as atopic dermatitis) has become increasingly common over recent decades, especially in industrialized countries, suggesting that environmental or lifestyle factors like diet could impact rates of disease. It is well established that sodium, consumed primarily in the form of salt, increases the risk of hypertension and heart disease through pro-inflammatory mechanisms. The role of sodium on other chronic inflammatory conditions like eczema has been less well-studied. (more…)
Aging, Author Interviews, Exercise - Fitness, JAMA, USPSTF / 10.06.2024

MedicalResearch.com Interview with: Li Li, M.D., Ph.D., M.P.H Walter M. Seward Professor Chair of Family Medicine Director of population health University of Virginia School of Medicine Editor-in-chief of The BMJ Family Medicine Dr. Li joined the U.S. Preventive Services Task Force in January 2021 MedicalResearch.com: What is the background for this study? What are the main findings of the underlying studies? Response: Falls are the leading cause of injuries in older adults and can lead to serious disability and even death. To help prevent these incidents, the Task Force looked at the current evidence on ways that primary care clinicians can help prevent falls in adults aged 65 and older who live at home and are more likely to fall. We concluded that healthcare professionals should recommend exercise interventions for adults aged 65 and older who are at increased risk for falls. This could include gait, balance, and functional training, as well as strength, resistance, and flexibility training. Clinicians can also talk with their older patients who are most likely to fall about whether additional interventions might be helpful to reduce their risk of falling. (more…)
