Author Interviews, Environmental Risks, Infections, PNAS / 14.03.2024

MedicalResearch.com Interview with: Dr. Fangqun Yu PhD Senior Research Faculty Atmospheric Sciences Research Center University Albany, State University of New York https://www.albany.edu/~yfq   Dr. Arshad Arjunan Nair PhD Postdoctoral Associate Atmospheric Sciences Research Center University at Albany, State University of New York https://www.albany.edu/~an688965   MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Fangqun Yu: Legionnaires’ disease is a severe form of pneumonia with a fatality rate of 10-25% caused by inhaling or aspirating Legionella, bacteria that thrive in built environment water systems. Those most vulnerable to this disease are male, over 50 years of age, have a history of smoking, have chronic respiratory diseases, diabetes, are immunocompromised, and/or minorities. The US observed a nearly nine-fold increase in Legionnaires’ disease between 2000 and 2018, with New York State having one of the highest increases in disease rates. The reasons for the increase in incidence were unclear prior to this study. In our study, we found: (1) Declining sulfur dioxide concentrations (SO2) are strongly correlated with the increase in legionellosis cases and a physical mechanism explaining this link is proposed, (2) A geostatistical epidemiological analysis links the disease with exposure to cooling towers, and (3) Climate and weather are ruled out as factors responsible for the long-term increase in case numbers (outside of seasonal trends).

Author Interviews, COVID -19 Coronavirus, Infections, NYU / 14.03.2024

MedicalResearch.com Interview with: Mukundan G. Attur, PhD Associate Professor, Department of Medicine NYU Grossman School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response:  The study investigates the potential protective effects of a genetic variant of IL1RN against inflammation and severe outcomes, particularly in COVID-19. Previous research indicates that carriers of this genetic variant may experience less severe radiographic knee osteoarthritis and decreased inflammation in rheumatoid arthritis patients. Given the emergence of cytokine release syndrome in COVID-19 patients, the researchers sought to understand whether the same genetic variant could offer protection against inflammation and potential death in COVID-19 cases.

Author Interviews, Sleep Disorders / 12.03.2024

MedicalResearch.com Interview with: Soomi Lee, PhD Associate Professor | Department of Human Development and Family Studies | Center for Healthy Aging Director of STEALTH Lab: https://sites.psu.edu/stealth/ The Pennsylvania State University MedicalResearch.com: What is the background for this study? Response:  Sleep quantity and quality decline with advancing age; a risk of chronic conditions also increases with age. While previous studies report that poor sleep is a significant risk for chronic conditions, many have focused solely on a single dimension of sleep, such as duration, thereby limiting the ability to assess multiple co-occurring dimensions and their associations with chronic conditions. This study aimed to evaluate multiple dimensions of sleep health, including regularity, satisfaction, alertness, efficiency, and duration. By analyzing data from a national sample of adults (n=3,683) collected over two time points spanning a decade, the study identified four distinct sleep health phenotypes: good sleepers, insomnia sleepers, weekend catch-up sleepers, and nappers.

Author Interviews, Cancer Research, Microbiome / 07.03.2024

MedicalResearch.com Interview with: Dr Ashray Gunjur MBBS (Hons), B. Med Sci, MPHTM FRACP Clinical Research Training Fellow Melbourne, Australia   MedicalResearch.com: What is the background for this study? Response: As background, the last ~5 years have seen a surge of interest in the relationship between gut microbiota and cancer response to immune checkpoint blockade (ICB). We know that though a fraction of many different cancer types will respond to these therapies, it is currently very hard to predict who that will be- so ‘microbiome’ based biomarkers to select patients, or even strategies to change a patient’s microbiome to enhance their chance of responding, are very attractive. A key challenge, however, has been a lack of consistency in the microbes associated with response or non-response across different studies from different regions. While geographic, methodological, and technical variation likely contribute to this, most studies examined the gut microbiome at a genus- or species- taxonomic rank level, while we know there is significant intra-species (strain-level) diversity. As such, one of our key research questions was whether we could improve the reproducibility of microbial ‘signatures’ of response across cohorts using higher resolution approaches- with our hypothesis being that strain-resolution signatures would outperform species- or lower resolution signatures. We obtained our signature by analysing baseline faecal samples from the CA209-538 clinical trial, a wonderful investigator-initiated study sponsored by the Olivia Newton-John Cancer Research Institute (Melbourne, Australia). I was fortunate enough to work on this trial as a clinical investigator while training to be a medical oncologist. (more…)
Author Interviews, Cognitive Issues, COVID -19 Coronavirus, Imperial College, NEJM / 29.02.2024

MedicalResearch.com Interview with: Prof. Adam Hampshire Ph.D. Faculty of Medicine, Department of Brain Sciences Professor in Restorative Neurosciences Imperial College London MedicalResearch.com: What is the background for this study? Response: Cognitive symptoms after coronavirus disease 2019 (Covid-19), the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), are well-recognized. Whether objectively measurable cognitive deficits exist and how long they persist are unclear. (more…)
AHA Journals, Author Interviews, Biomarkers, Brigham & Women's - Harvard, Heart Disease / 27.02.2024

MedicalResearch.com Interview with: Rosangela Akemi Hoshi, Ph.D. Lemann Foundation Cardiovascular Research Postdoctoral Fellowship Center for Lipid Metabolomics Divisions of Preventive and Cardiovascular Medicine Brigham and Women's Hospital Boston, MA  MedicalResearch.com: What is the background for this study? Would you describe the IgG N-glycan profile? Response: Glycans are sugar coatings of proteins, made of monosaccharide building blocks, that are involved in a variety of biological pathways.  Different sugar structures can dictate or modify the protein’s activity through specific interactions with cellular receptors. For example, proteins lacking glycans have a reduced level or a complete loss of function. Glycans are of such importance that the 2022 Nobel Prize in chemistry was awarded for glycan-based science. In this study, we examined glycans attached to Immunoglobulins G (IgG) and their link with incidence of cardiovascular disease (CVD) due to their impact on IgG inflammatory properties. Since inflammation is not only a cause, but also an aggravating factor and a mediator of a worse prognosis in cardiometabolic disorders and CVD, we investigated whether different glycan structures may characterize an at-risk phenotype for CVD development. Determining glycan profiles involved in multiple conditions can serve prognostic and diagnostic purposes. Yet, unlike other types of macromolecules, glycans are still not as much explored, characterizing a promising but underappreciated class that should be further investigated. (more…)
Author Interviews, Nature, Technology, University of Pittsburgh / 26.02.2024

MedicalResearch.com Interview with: Jishnu Das, Ph.D. Center for Systems Immunology Departments of Immunology and Computational & Systems Biology, Assistant Professor School of Medicine University of Pittsburgh MedicalResearch.com:  What is the background for this study? How does this new AI model work?  How is it different from other models? Response: Modern multi-omic technologies generate an enormous amount of data across scales of organization, and with differing resolution. While recent machine learning methods have harnessed these to predict clinical/physiological outcomes, they are often black boxes that do not provide meaningful inference beyond prediction. Differences in data generation modalities, redundancy in the data, as well as large numbers of irrelevant features make inference of biological mechanisms from high-dimensional omic datasets challenging. To address these challenges, we developed a machine learning technique called SLIDE (Significant Latent Factor Interaction Discovery and Exploration). We reasoned that features that are directly measured by current technologies are constrained by strengths and weaknesses of current platforms. So, while some observed features may be excellent correlates of outcomes of interest, inferring biological mechanisms from these multi-omic datasets requires us to delve beyond the observable into the hidden states, i.e., latent factors. These hidden states encapsulate the true drivers of underlying biological processes and capture a complex multi-scale interplay between entities measured by these datasets. Our method moves beyond simple biomarkers/correlates (“the what”) to hidden states that actually explain clinical/physiological outcomes (“the how” and “the why”). (more…)

MedicalResearch.com Interview with: Benjamin N. Breyer, MD, MAS Department of Urology Department of Epidemiology and Biostatistics University of California, San Francisco Adrian M. Fernandez, MD Department of Urology University of California, San Francisco MedicalResearch.com: What is the background for this study? Response: This is a cross-sectional study utilizing data from the National Electronic Injury Surveillance System (NEISS) to identify injuries and hospitalizations related to electric bicycles accidents in the United States from 2017-2022.  The NEISS database collates injury data associated with products, including electric bicycles, and samples a nationally representative selection of emergency departments. National estimates of e-bicycle injuries and hospitalizations were derived using estimates accounting for NEISS complex survey design. (more…)
Aging, Author Interviews, Dermatology / 19.02.2024

MedicalResearch.com Interview with: Frank Wang MD William B. Taylor Endowed Professor of Clinical Dermatology Associate Professor, Dermatology Associate Chair for Education Assistant Program Director, Dermatology Residency Program University of Michigan Ann Arbor, Michigan MedicalResearch.com: What is the background for this study? How is the cross-linked hyaluronic acid obtained? Where was it injected? Response: As the skin undergoes photoaging due to chronic exposure to ultraviolet light, it loses dermal collagen, which in turn leads to wrinkling, lines, and loss of support. The loss of collagen is, in large part, due to reduced function of the skin’s collagen-producing cells, dermal fibroblasts. We wanted to investigate whether it was possible to reverse the decreased function of fibroblasts in photodamaged skin, by introducing a space-filling material into the dermis, injected CL-HA dermal filler. The CL-HA filler we used was donated to us for research purposes. We performed injections of CL-HA into the mid-dermis (as is normally done when injected into the face) of severely photoaged forearm skin of human participants over the age of 60. We then examined skin samples at various time points, including 1, 2, 3 and 4 weeks and 3, 6, 9, and 12 months post-injection. (more…)

MedicalResearch.com Interview with: A/Prof. Joshua Ooi, PhD Head, Regulatory T-cell Therapies Translational Research Facility Clinical Sciences at Monash Health, Monash University MedicalResearch.com: What is the background for this study? Response: In 2017, we published a landmark Nature paper showing that people who are protected from autoimmune disease have specialized molecules on immune cells. These specific molecules are missing in patients that develop autoimmune disease. (more…)
Author Interviews, Breast Cancer, Cancer Research / 04.02.2024

MedicalResearch.com Interview with: Takemi Tanaka, Ph. D. Professor, Stephenson Cancer Center Department of Pathology, School of Medicine University of Oklahoma Health Science Center MedicalResearch.com: What is the background for this study? Response: Our previous cohort study has shown that breast cancer progresses 60 days after diagnostic biopsy in early-stage ER+ breast cancer. Others have also reported increased breast cancer mortality due to surgery delay. These observations raised the question of how slow-growing ER+ breast cancer progresses so quickly in just 60 days following diagnosis, prompting us to hypothesize whether needle biopsy of breast tumors accelerates pro-metastatic changes.

Addiction, Author Interviews, Gastrointestinal Disease, Opiods / 03.02.2024

MedicalResearch.com Interview with: Joshua D. Madera, MD Department of Medical Education Geisinger Commonwealth School of Medicine Scranton PA What is the background for this study? Response: The US population continues to be drastically impacted by the opioid epidemic, with opioid-related deaths significantly increased compared to European countries. While prescription opioid distribution has gradually declined since its peak in 2011 [1], the rate of opioid prescriptions remains increased compared to 2000. Furthermore, there is considerable interstate variability in opioid distribution across the US. Identifying patterns in this variability may guide public health efforts to reduce opioid-related harms. Therefore, the primary objective of this study [2] from Geisinger Commonwealth School of Medicine was to explore variations in production quotas and state-level distribution of ten prescription opioids between 2010 and 2019.

Author Interviews, Respiratory, Social Issues, University of Michigan / 31.01.2024

MedicalResearch.com Interview with: Wilson N. Merrell
Ph.D. Student
Department of Psychology
University of MichiganWilson N. Merrell Ph.D. Student Department of Psychology University of Michigan MedicalResearch.com: What is the background for this study? Response: From the common cold to COVID-19, people get sick all the time. Because our social worlds don’t pause just because we are feeling ill, we often still need to navigate in-person events ranging from work and school to first dates and family dinners even while we’re feeling under the weather. In these kinds of social situations, do we always tell others when we’re feeling sick, or are there times when we may want to downplay our illness? After all, we tend to react negatively to, find less attractive, and steer clear of people who are sick with infectious illness. To the extent that we want to avoid these negative social outcomes while sick, it therefore makes sense that we may take steps to cover up our sickness in social situations. Given that this concealment could serve individual social goals (like allowing you to connect with others) at the cost of broader harms to public health (through the spread of infectious disease), we found this behavior both theoretically novel and practically timely.

Accidents & Violence, Aging, Author Interviews, Cannabis, JAMA / 19.01.2024

MedicalResearch.com Interview with: Patricia Di Ciano, PhD Scientist, Institute for Mental Health Policy Research, Centre for Addiction and Mental Health Assistant Professor, Department of Pharmacology and Toxicology University of Toronto Campbell Family Mental Health Research Institute Collaborative Program in Neuroscience MedicalResearch.com: What is the background for this study? Response: It is now fairly well established that cannabis has a detrimental effect on driving. The most consistently reported effect of cannabis on driving is to increase ‘weaving’ on the road. We know that cannabis use is on the rise in people over 65 years of age. In fact, over the past few years cannabis use is increasing the most in this age group. Despite this, there are few studies of the effects of cannabis on people over 65; most studies have been conducted on younger adults. We know that there are important age-related changes in the way the body works that may alter the impact of cannabis on the body. Also, older adults may have more experience with cannabis and this can change the effects of cannabis. (more…)
Author Interviews, Mental Health Research, Pharmaceutical Companies / 14.01.2024

MedicalResearch.com Interview with: Lauren Davis Lauren C. Davis, MBS Department of Medical Education Geisinger Commonwealth School of Medicine Scranton, PA 19409   MedicalResearch.com: What is the background for this study? Response: Financial conflicts of interest (COIs) resulting from ties between academia and industry have been under scrutiny for their potential to hinder the integrity of medical research. COIs can lead to implicit bias, compromise the research process, and erode public trust (1-6). The American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM), standardizes symptom criteria and codifies psychiatric disorders. This manual contributes to the approval of new drugs, extensions of patent exclusivity, and can influence payers and mental health professionals seeking third-party reimbursements. Given the implications of the DSM on public health, it is paramount that it is free of industry influence. Previous research has shown a high prevalence of industry ties among panel and task force members of the DSM-IV-TR and DSM-5, despite the implementation of a disclosure policy for the DSM-5 (7,8). This study (9) determined the extent and type of COIs received by panel and task-force members of the DSM-5-TR (2022) (10). As the DSM-5-TR did not disclose COI, we used the Center for Medicare and Medicaid Services Open Payments (OP) database (11) to quantify them. (more…)
Author Interviews, Brain Injury, Brigham & Women's - Harvard, Inflammation / 14.01.2024

MedicalResearch.com Interview with: Samir Mitragotri Ph.D. Hiller Professor of Bioengineering Hansjorg Wyss Professor of Biologically Inspired Engineering Area Chair, Bioengineering Core Faculty Member, Wyss Institute for Biologically Inspired Engineering Harvard John A. Paulson School Of Engineering And Applied Sciences MedicalResearch.com: What is the background for this study? Response: Traumatic brain injury (TBI) has a heavy burden on the world, affecting ~70 million people globally each year. Despite its prevalence, there are no clinically approved treatments beyond symptom management. There is an urgent need to develop effective therapies to alleviate the damage caused by TBI.   MedicalResearch.com:  What do macrophages typically do?  As part of the innate immune system, macrophages migrate to areas of injury to eat pathogens or debris and manage inflammation in response to injury or infection. However, in the majority of cases of TBI, there is no actual infection from a foreign pathogen, leading to excessive inflammation that spreads damage beyond the initial impact. (more…)
Author Interviews, Cost of Health Care, JAMA, Kidney Disease, Medicare / 11.01.2024

MedicalResearch.com Interview with: Kalli Koukounas, MPH Ph.D. Student, Health Services Research Brown University School of Public Health Providence, RI MedicalResearch.com: What is the background for this study? Response:  On Jan. 1st, 2021, the Centers for Medicare and Medicaid Services (CMS) implemented the End-Stage Renal Disease Treatment Choices (ETC) Model, one of the largest randomized tests of pay-for-performance incentives ever conducted in the US. The goal of the model was to enhance the use of home dialysis and kidney transplant or waitlisting among kidney failure patients in traditional Medicare. The model randomly assigned approximately 30% of US dialysis facilities and nephrologists to receive financial incentives, ranging from bonuses of 4% to penalties of 5%, based on their patients’ use of home dialysis and kidney transplant/waitlisiting. The payment adjustments apply to all Medicare-based reimbursement for dialysis services. Prior research has demonstrated that dialysis facilities that disproportionately serve populations with high social risk have lower use of home dialysis and kidney transplant, raising concerns that these sites may fare poorly in the payment model. Using data released by CMS, we examined the first year of ETC model performance and financial penalties across dialysis facilities, stratified by the measured social risk of the facilities’ incident patients.

Author Interviews, Neurological Disorders, NYU, Pediatrics / 09.01.2024

MedicalResearch.com Interview with: Laura Gould, MSc, MA, PT Research Scientist SUDC Registry and Research Collaborative Comprehensive Epilepsy Center Department of Neurology NYU Langone Grossman School of Medicine     MedicalResearch.com: What is the background for this study? Response: Sudden Unexplained death in childhood (SUDC) is the unexplained death of a child on or after their 1st birthday that remains unexplained after a comprehensive death investigation. About 400 SUDC occur annually between the ages of 1-18, but more than half occur in toddlers, aged 1-4 years. Since most deaths are sleep related and unwitnessed with unremarkable autopsies, mechanisms of deaths have eluded our understanding. Febrile seizures are common in young children; ~ 3% of US children 6 months to 5 years will experience one. SUDC however has been associated with a 10-fold increase in febrile seizures; our study is the first to implicate them at time of death. The SUDC Registry and Research Collaborative (www.sudcrrc.org) at NYU Langone Health has enrolled over 300 cases of unexplained child death; seven with audiovisual recordings from the child’s bedroom during their last sleep period. More than 80% of the cases enrolled in the registry were children 1-4 years at the time of death. The seven cases with videos were aged 13-27 months with normal development and no pathogenic disease-causing variants by whole exome sequencing. (more…)
Author Interviews, Autism, JAMA, Pediatrics, Technology / 08.01.2024

MedicalResearch.com Interview with: Karen F. Heffler, MD Researcher, Autism Spectrum Disorder Associate Professor, Department of Psychiatry Drexel University College of Medicine Philadelphia, PA MedicalResearch.com: What is the background for this study? children-watching-tv-pexels-photo-4740522 Response: Atypical sensory processing is common in neurodevelopmental disorders, affecting approximately 60% of children with ADHD and up to 90% of children with autism. Sensory symptoms are associated with hyperactivity, restricted/repetitive behavior, irritability, behavioral problems, and emotional dysregulation. Sensory-related meltdowns and symptoms can be very disruptive to family-life, interfere with family participation in community events and are associated with increased caregiver stress. Prior to this study there was little understanding of potential risk factors for atypical sensory processing. The researchers used data from the National Children’s Study to determine the association between early-life screen time and sensory processing outcomes among toddlers. (more…)

Response: Adding salt to foods is a behavior reflecting long-term preference to salty diets. High sodium intake is a major risk factor for chronic kidney disease. In our previous studies, we have found that adding salt to foods at the table is related to various disorders including cardiovascular diseases, diabetes, and mortality.  (more…)
Author Interviews, Gender Differences / 03.01.2024

MedicalResearch.com Interview with: Christian Carbe, PhD Department of Medical Educatio Geisinger Commonwealth School of Medicine Scranton, PA 18509   MedicalResearch.com: What is the background for this study? Response: Transgender patients often experience pronounced healthcare disparities compared to their cisgender counterparts. Disparities in the treatment of transgender patients resulting from deficiencies in cultural competency perpetuate poor health outcomes, such as suicide, substance misuse, depression, harassment, and victimization. Individuals within the transgender community often face systemic barriers within the medical field, including a lack of comprehensive access to health insurance, discrimination from providers, and incompetent provider training in transgender-specific health needs. This report evaluated the changes in knowledge, attitudes, and beliefs of the psychosocial and medical needs of the transgender community among first-year undergraduate medical students that attended the Northeastern Pennsylvania Trans Health Conference. Our broader goal is to develop and refine longitudinal interventions to improve skills and sensitivity of future physicians to provide compassionate and competent gender diverse and transgender healthcare.

How does the JYNNEOS vaccine differ from the smallpox vaccine? Response: JYNNEOS vaccine is a smallpox vaccine that was repurposed for Mpox given the similarities between the two viruses (smallpox and mpox). The vaccine (JYNNEOS) had been studied in people without HIV therefore there was a gap in knowledge in how this vaccine, especially the small dose (intradermal dose), would work in patients with HIV. These patients resulted to be the most affected by the mpox outbreak suffering the worse outcomes of the disease with the highest death rates. (more…)

MedicalResearch.com Interview with: Prof. Enomoto, Masaru Department of Hepatology Graduate School of Medicine Osaka Metropolitan University Osaka, Japan MedicalResearch.com: What is the background for this study? Response: This research was conceived out of the use of generative AI drawing upon past experience in selecting a large amount of literature over an extended amount of time. In recent years, generative AI, such as ChatGPT, has gained attention and is being used in various fields, including information gathering and idea generation. In the medical field in particular, it is challenging to gather pertinent data as the volume of information proliferates on a daily basis, so there is a need to improve the efficiency of information collection.

Author Interviews, Cannabis, Medical Imaging, Pulmonary Disease / 10.12.2023

MedicalResearch.com Interview with: Jessie Kang, MD, FRCPC Assistant professor Department of Diagnostic Radiology Faculty of Medicine Dalhousie University   MedicalResearch.com: What is the background for this study?
  • Marijuana is the most widely used illicit psychoactive substance in the world.
  • Use has increased in Canada since legalization of non-medical marijuana in 2018.
  • It is commonly believed that smoking marijuana is not harmful to the lungs. There is an abundance of established research that identifies the harms of cigarette smoking. In contrast, very little is known about the effects of marijuana smoking, and even less research has been done on the combined effects of smoking marijuana and cigarettes.
To determine the effects of marijuana and cigarette smoking, we examined the chest CT images of four patient groups: non-smokers, cigarette smokers, marijuana smokers, and combined marijuana and cigarette smokers. Marijuana smokers included in the study had smoked marijuana at least four times a month for two years. Patients who ingested marijuana via edibles or oral drops were excluded from the study. (more…)

MedicalResearch.com Interview with: Nathan A. Berger, M.D. Distinguished University ProfessorHanna-Payne Professor of Experimental MedicineProfessor of Medicine, Biochemistry, Oncology and GeneticsDirector, Center for Science, Health and SocietyCase Western Reserve University School of Medicine   Rong Xu, PhD Professor, Biomedical Informatics Director, Center for Artificial Intelligence in Drug Discovery Case Western Reserve University School of Medicine     MedicalResearch.com: What is the background for this study? Response: 75% of the US Population has overweight or obesity and 15% has Type 2 Diabetes. Both overweight/obesity and diabetes promote increased incidence and worse prognosis of colorectal cancer. The new GLP1RA drug class are rapidly becoming the most effective treatment for both diabetes and overweight/obesity. By controlling diabetes and overweight/obesity, we hypothesized that the GLP1RAs might be effective at reducing incidence of colorectal cancer. (more…)
Author Interviews, Brigham & Women's - Harvard, Lancet, Pediatrics, Vitamin D / 05.12.2023

MedicalResearch.com Interview with: Dr Ganmaa Davaasambuu MD PhD Associate Professor Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? Response: The crucial role of vitamin D in facilitating calcium absorption from the diet and promoting calcium deposition in bones (known as 'mineralization') has been a long-established understanding. Furthermore, some observational studies have reported an association between low vitamin D levels and a heightened risk of bone fractures in children. This raised the possibility that vitamin D supplements could potentially play a role in decreasing fracture risk in children with initially low baseline levels. However, clinical trials assessing the causal link between low vitamin D status and reduced fracture risk were necessary, and such trials had not been conducted before. (more…)
Alzheimer's - Dementia, Author Interviews, Weight Research / 28.11.2023

MedicalResearch.com Interview with:

Mahsa Dolatshahi, M.D., M.P.H. Post-doctoral research fellow Mallinckrodt Institute of Radiology (MIR) Washington University School of Medicine St. Louis MedicalResearch.com: What is the background for this study? Response: Obesity at midlife is recognized as a risk factor for developing Alzheimer disease decades afterwards. However, body mass index on its own does not adequately represent the risks associated with obesity. In this study, we went beyond BMI and considered anatomical distribution of body fat, including the metabolically active visceral fat in the belly, and showed its association with Alzheimer pathology in the form of amyloid proteins. In addition, visceral fat along with obesity and insulin resistance were associated with thinning of brain cortex, as early as midlife. (more…)
Aging, Author Interviews, Frailty, Infections / 18.11.2023

MedicalResearch.com Interview with: Hira Mohyuddin, PGY-2 Psychiatry Residency Training Program The George Washington University MedicalResearch.com: What is the background for this study? Response: Frailty has become increasingly significant as the global population grows older, as this syndrome is linked with a higher mortality and morbidity in aging. Causes contributing to frailty are poorly understood, but it seems that the role of inflammation is very likely. While other chronic infections were shown to precipitate and perpetuate inflammation that contributes to the development of frailty, no prior study has previously focused on possible links between Toxoplasma gondii and geriatric frailty. Benefiting from a collaboration with Spanish and Portuguese researchers, we have now tested, for the first time to our knowledge, this possible association. (more…)

PhD Candidate Clinical Pharmacy
Radboud University Medical Center
Department of Pharmacy
Nijmegen, the Netherlands Lisa-Marie Smale, PharmDPhD Candidate Clinical PharmacyRadboud University Medical CenterDepartment of PharmacyNijmegen, the Netherlands   MedicalResearch.com: What is the background for this study? Response: Cancer drugs are not always fully used by patients, while these drugs are mostly expensive and environmentally damaging, both in production and (waste) disposal. Therefore we investigated whether unused drugs of patients can be collected, verified of quality by a pharmacy, to be redispensed to other patients instead of being disposed of. We were interested whether such an approach ultimately leads to lower environmental impacts and costs. (more…)
