Author Interviews, COVID -19 Coronavirus / 19.07.2023

MedicalResearch.com Interview with: Prof. Tommy Dickey Ph.D. Distinguished Professor Emeritus Geography Department University of California Santa Barbara Santa Barbara, CA covid-sniffing-dogs-tom-trainingMedicalResearch.com: What is the background for this study? Response:  I became interested in dog's sense of smell several years ago while doing therapy dog demonstrations at the California Science Center in Los Angeles during a special traveling exhibit "Dogs! A Science Tail." (Now at the Orlando Science Center).  I did a lot of research on this topic and taught children about it through the Los Angeles Public Library using my Great Pyrenees therapy dogs. Then, COVID broke out and I expanded my research into any work being done to possibly utilize scent dogs for screening and testing for COVID.  I found only a few such studies.  However, I fortuitously met Heather Junqueira of BioScent, Inc. (in Florida) online and she was beginning to successfully teach her beagles to detect COVID-related odors.  She agreed to co-author a peer-reviewed review paper with me.  That led to our first paper - Dickey, T, Junqueira, H. Toward the use of medical scent dogs for COVID-19 screening. J Osteopath Med 2021;1(2): 141-148. https://doi.org/10.1515/jom-2020-0222 When the COVID pandemic began to wane at the beginning of this year, I felt that it would be the perfect time to do this comprehensive follow-up review to see how far COVID scent dog research had progressed. To our amazement, research efforts had increased by almost tenfold and involved over 400 scientists using over 31,000 samples (including sniffings) from over 30 countries and that 29 peer reviewed papers had been published. Heather’s inspiration for doing scent dog work came when her father contracted cancer and she wanted to find better diagnostics.  She has since been successful in detecting non-small cell lung cancer with her trained beagles as well as COVID.

Author Interviews, Genetic Research, JAMA, Pediatrics / 17.07.2023

MedicalResearch.com Interview with: Prof. Jonathan Davis, MD, Chief of Newborn Medicine Tufts Medical Center and   Jill Maron, MD, MPH Chief of Pediatrics Women & Infants Hospital of Rhode Island   MedicalResearch.com: What is the background for this study? Response: The Genomic Medicine for Ill Neonates and Infants (GEMINI) trial was designed to be the first comparative study to explore the diagnostic yield, clinical utility and time to diagnosis between whole genomic sequencing (WGS) and a targeted genomic sequencing panel specifically designed to detect gene disorders that present in early life. GEMINI was a US based study that enrolled 400 hospitalized infants, along with their available parents, suspected of having an undiagnosed genetic diagnosis. Every participant underwent testing on each platform simultaneously, allowing us to better understand the limitations and advantages of each approach. (more…)
Author Interviews, Endocrinology, Hormone Therapy, Menopause / 17.07.2023

MedicalResearch.com Interview with: Jerilynn C Prior MD FRCPC (on behalf of all authors Professor of Endocrinology / Department of Medicine University of British Columbia Centre for Menstrual Cycle and Ovulation Research www.cemcor.ca BC Women’s Health Research Institute Vancouver BC Canada MedicalResearch.com: What is the background for this study? Response: Night sweats and hot flushes/flashes (together called vasomotor symptoms, VMS) disturb women who are still menstruating (in perimenopause) are at least as much or more than  menopausal women (without flow for a year or more)1. However, although studies have investigated various treatments for perimenopausal hot flushes/flashes, none have proven effective in these women who are also likely to be having heavy flow, breast tenderness, and premenstrual symptoms related to high and variable estrogen levels. These include randomized controlled trials (RCT) of the birth control pill2, and gel estrogen in women using a progestin-releasing IUD3. Neither showed that therapy was more effective than placebo; both studied too few participants to provide a clear answer. Meanwhile, major medical organization guidelines recommend menopausal hormone therapy (MHT, usually of estrogen with a progestin) for any women younger than 60 years old who are bothered by night sweats and hot flushes 4-6. However, there are no scientific RCT studies showing MHT is effective for perimenopausal night sweats and hot flushes. Giving more estrogen to someone whose own estrogen levels are often high, also did not make clinical sense. We previously performed an RCT showing that oral micronized progesterone (progesterone) was effective for menopausal hot flushes and also improved sleep7. Given that progesterone levels in perimenopausal women are declining, we considered that perimenopausal progesterone therapy for night sweats needed testing. (more…)
Addiction, Author Interviews, Cannabis, Mental Health Research / 12.07.2023

MedicalResearch.com Interview with: Jessica Kruger PhD Clinical Associate Professor of Community Health and Health Behavior University at Buffalo School of Public Health and Health Professions MedicalResearch.com: What is the background for this study? Response: The 2018 Farm Bill authorizing hemp production led to new cannabinoids in the consumer marketplace. As the market becomes increasingly saturated with suppliers, companies continually diversify available products. The rapid emergence of novel cannabinoids outpaces systematic research necessary to inform regulations and harm reduction. Empirical evidence is needed to guide policies, practices, and education of consumers. Product manufacturers, social media participants, and cannabis oriented on-line news sources have claimed that THC-O-acetate is a "psychedelic" cannabinoid, producing experiences similar to those associated with LSD, psilocybin, mescaline, and DMT.

Author Interviews, COVID -19 Coronavirus / 10.07.2023

MedicalResearch.com Interview with: Fernanda Lessa, MD, MPH Chief, CDC’s International Infection Control Program Co-author of the paper MedicalResearch.com: What is the background for this study? What are the main findings? Response: Data from low- and middle-income countries on the impact of the COVID-19 pandemic on antibiotic use among outpatients are sparse. This study evaluated the changes in prescribing rates of antibiotics commonly prescribed for respiratory tract infections by outpatient providers among adults in Brazil. We observed increases during the pandemic in outpatient prescriptions of azithromycin and ceftriaxone of up 360% and 90%, respectively, based on age and sex. (more…)
Anesthesiology, Author Interviews, Cannabis, JAMA, Opiods, Surgical Research, University Texas / 10.07.2023

MedicalResearch.com Interview with: Paul Potnuru, MD Assistant Professor Anesthesiology, Critical Care and Pain Medicine The John P. and Kathrine G. McGovern Medical School The University of Texas Health Science Center at Houston UTHealth MedicalResearch.com: What is the background for this study? Response: The use of cannabis is on the rise in the United States, as it becomes increasingly legally accepted and is viewed as harmless. Furthermore, the potency of cannabis is steadily increasing over time. There is some evidence from previous studies that compared to non-users, cannabis users require more anesthetics, have higher pain after surgery that requires more opioids, and have an increased risk of postoperative nausea and vomiting. Given this context of increased usage and potential risks during surgery, we conducted a study to examine the impact of cannabis use on patients undergoing surgery. (more…)
Author Interviews, Hepatitis - Liver Disease, JAMA, Statins / 07.07.2023

MedicalResearch.com Interview with: Carolin Victoria Schneider, MD Physician-Scientist at RWTH Aachen Former Postdoctoral Fellow at UPenn, Rader Lab MedicalResearch.com: What is the background for this study? Response: Our study was prompted by the ongoing global health crisis related to liver disease, which claims over 2 million lives annually. We noted the emerging literature suggesting the hepatoprotective properties of statins, which include anti-inflammatory, antiproliferative, antiangiogenic, and immunomodulatory effects. However, we noticed a significant gap in understanding these effects in the context of the general population, especially among individuals without a history of known liver disease. Together with our excellent first author Mara Vell, I embarked on a journey aimed to fill this significant knowledge gap. (more…)
Author Interviews, JAMA, OBGYNE / 07.07.2023

MedicalResearch.com Interview with: Dorothy A. Fink, MD Deputy Assistant Secretary for Women's Health Director, Office on Women's Health US Department of Health & Human Services Rockville, MD MedicalResearch.com: What is the background for this study? Response: Delivery-related mortality in U.S. hospitals has decreased for all racial and ethnic groups, age groups, and modes of delivery while the prevalence of severe maternal mortality (SMM) increased for all patients, with higher rates for racial and ethnic minority patients of any age. This study specifically looked at inpatient delivery-related outcomes and found a 57% decrease from 2008-2021. The decreasing mortality rates within the inpatient delivery setting demonstrated as statistically significant and a welcome finding for all women. This study also looked with greater granularity at the impact of race, ethnicity, and age. Mortality for American Indian women decreased 92%, Asian women decreased 73%, Black women decreased 76%, Hispanic women decreased 60%, Pacific Islander women decreased 79%, and White women decreased 40% during the study period.

Author Interviews, Cannabis / 07.07.2023

MedicalResearch.com Interview with: Edward Liu, BA Second year medical student Department of Medical Education Geisinger Commonwealth School of Medicine Scranton, PA MedicalResearch.com: What is the background for this study? Response: The use pattern of two FDA approved cannabinoids, dronabinol (Marinol) and cannabidiol (Epidiolex) has not been previously studied. Dronabinol has been approved in the United States since 1985 for chemotherapy induced nausea as well as vomiting and HIV-induced anorexia,1,2 whereas cannabidiol has been approved since 2018 to treat childhood epileptic disorders, Lennox-Gastaut and Dravet syndrome.3 This longitudinal study examined Medicaid claims between 2016-2020 for these two prescription cannabinoids to better comprehend the state-level pharmacoepidemiologic trends and distribution of these drugs in US Medicaid amidst the increasing use of non-pharmaceutical formulations of cannabis.

Aging, Author Interviews, Mental Health Research, Sleep Disorders / 02.07.2023

MedicalResearch.com Interview with: Valentina Paz, M.Sc Ph.D.  Student Research and teaching assistant Universidad de la República, UruguayHon. Research AssistantMRC Unit for Lifelong Health & Ageing Department of Population Science & Experimental MedicineInstitute of Cardiovascular ScienceUniversity College London MedicalResearch.com: What is the background for this study? Response: Prior research indicates that napping can enhance performance on specific cognitive tasks. However, some authors argue that the advantages derived from napping may vary between individuals who frequently have a nap and those who never naps. Furthermore, it remains to be seen whether habitual daytime napping has a positive or negative impact on cognition and the association between napping and brain volume is not well characterized. Therefore, our study aimed to examine whether the association between genetic liability to daytime napping, cognitive function, and brain volumes might be causal using a technic called Mendelian randomization and the UK Biobank.

Author Interviews, Depression, JAMA, Mental Health Research, NYU, USPSTF / 27.06.2023

MedicalResearch.com Interview with: Gbenga Ogedegbe, MD, MPH Dr. Adolph & Margaret Berger Professor of Population Health Director, Division of Health & Behavior Director Center for Healthful Behavior Change Department of Population Health NYU Langone Health NYU School of Medicine Member of the U.S. Preventive Services Task Force   MedicalResearch.com: What is the background for this study? Response: Depression and anxiety disorders are common mental health conditions affecting the lives of many adults in the U.S. The Task Force cares deeply about the health of people nationwide, so we reviewed the latest evidence on how best to support the mental health of adults in primary care. MedicalResearch.com: What are the main findings? Response:  The evidence shows us that all adults should be screened for depression and those under 65 should also be screened for anxiety. These recommendations apply to everyone without signs or symptoms of depression or anxiety. We also strongly encourage anyone who has signs of depression or anxiety to talk with their clinician so that they can get the care they need. (more…)
Author Interviews, Biomarkers, Brigham & Women's - Harvard, Diabetes, Endocrinology / 26.06.2023

MedicalResearch.com Interview with: Dr. Bita Zahedi MD MA Endocrinologist Massachusetts General Hospital MedicalResearch.com: What is the background for this study? Response: The purpose of this study was to develop and validate a measure of dietary advanced glycation end-products (AGEs) to investigate the role of dietary AGEs in diabetic disease processes.  AGEs are a group of highly reactive compounds involved in the pathophysiology of diabetic complications, such as microvascular disease, cardiomyopathy, and possibly bone health. AGEs form through a nonenzymatic reaction between reducing sugars and free amino groups of proteins, lipids, and nucleic acids, also known as a Maillard or browning reaction. Endogenous AGE formation and accumulation is a normal part of metabolism and aging, however the process of glycation can be enhanced by hyperglycemia, hyperlipidemia, and increased oxidative stress. Additionally, AGEs can be absorbed from exogenous sources via consumption of various food items. Prior studies demonstrate that skin AGEs are predictive of Dietary AGEs (dAGEs) which are naturally present in certain uncooked foods, mainly animal-derived products, furthermore the method of food preparation can result in significant AGE formation. Considering the ubiquitous intake of dAGEs, it is possible that the consumption of exogenous AGEs contribute to AGE-induced oxidative stress, inflammation, and its subsequent detrimental sequalae.

Author Interviews, General Medicine, Health Care Systems, Heart Disease, JAMA / 26.06.2023

MedicalResearch.com Interview with: Dan P. Ly, MD, PhD, MPP Physician and an Assistant Professor Division of General Internal Medicine and Health Services Research David Geffen School of Medicine at UCLA MedicalResearch.com: What is the background for this study? Response: Cognitive biases, or ways of thinking that may deviate from rationality, are thought to influence physician decision-making, but there has been little large-scale evidence of their existence clinically. There is some large-scale evidence of the availability heuristic, under which the likelihood of an event is affected by how easily it comes to mind, but there’s little large scale evidence of other cognitive biases affecting physicians.  (more…)
Author Interviews, Cannabis, JAMA, OBGYNE, Pediatrics / 26.06.2023

MedicalResearch.com Interview with: Alex P. Miller, PhD TranSTAR T32 Postdoctoral Fellow Department of Psychiatry Washington University School of Medicine St. Louis, MO   MedicalResearch.com: What is the background for this study? Response: Adolescent cannabis use is increasing in the United States. Prior research suggests that people who start using cannabis earlier are more likely to engage in problematic use and also experience greater mental health challenges and socioeconomic disadvantages overall. For example, children who begin using cannabis early are more likely to have behavioral problems and disorders and are more less likely to complete school. In our study, we used data from the Adolescent Brain Cognitive Development (ABCD) Study, which is following nearly 12,000 kids across the nation to track behavior and brain development as well as health from middle childhood to young adulthood. We looked at what factors are associated with the initiation of cannabis use by age 12-14. (more…)
Author Interviews, Brigham & Women's - Harvard, Diabetes, Ophthalmology / 16.06.2023

MedicalResearch.com Interview with: Ali Hafezi-Moghadam, Ph.D., M.D Director, Molecular Biomarkers Nano-Imaging Laboratory (MBNI) Associate Professor of Radiology, Harvard Medical School Brigham and Women’s Hospital MedicalResearch.com: What is the background for this study? Response: “It is very easy to answer many fundamental biological questions” said Richard Feynman in his 1959 address, where he also offered his simple and ingenious solution: “you just look at the thing!”[1]. As a biologist, I am familiar with the challenges surrounding looking at things in the context of life. There is no single device or technology that lets me simply see the answers to my questions. How does diabetes harm the tissues in the body? When exactly does the pathology start and which molecules and cells are involved? Trying to answer these questions, I have spent the past two decades innovating new ways of quantifying expression of molecules in the living organism [2]. At the same time to study diabetes, we needed a realistic rodent model that mirrors the human disease. In collaboration with KC Hayes[3], we first introduced the Nile grass rat (NGR, Arvicanthis niloticus), a gerbil that recapitulates the main features of the human type 2 diabetes [4]. For visualization of early changes, the eye offers a unique site. Much of my lab’s work focused on the first effects of diabetes in the retina, the site of the neurons that perceive light in the back of the eye [5], [6], [7]. In recent studies, we focused on how diabetes affects the lens in the eye of our animals [8], [9]. Diabetes is a major risk factor for cataract formation, a condition during which the lens loses its original transparency to visible light. How diabetic cataracts are formed is not well understood. A popular and prevailing theory, termed “sugar cataracts”, has been around for over half a century. According to the sugar hypothesis of cataracts, the excess levels of the sugar molecule, glucose, in the lens are transformed through the polyol pathway into the sugar-alcohol sorbitol. The resulting osmotic dysbalance leads to swelling of the fiber cells and opacity of the lens. Even though the sugar hypothesis has never been proven, it was generally accepted and remained unchallenged for a very long time. That is where our latest experimental results became relevant.

Author Interviews, Endocrinology, Gender Differences, Weight Research / 16.06.2023

MedicalResearch.com Interview with: Francesca Galbiati, MD Clinical/Research fellow in Endocrinology Massachusetts General Hospital MedicalResearch.com: What is the background for this study? Response:  Arginine-vasopressin (AVP) is a neurohormone well known for its role in water balance regulation. It promotes renal water absorption in the kidney, to maintain normal sodium levels in the blood via a tightly controlled osmotic regulation. Besides AVP classical role, data have shown that AVP effects extend beyond water balance regulation. Animal studies have shown that AVP has metabolic effects, including reducing food intake, inducing lipolysis, and promoting muscle regeneration in male mice. Furthermore, AVP is regulated differently in males and females, and affects cognition differently across sexes, a phenomenon called sexual dimorphism. However, it is unknown whether its dimorphism translates to metabolism. Also, findings on AVP metabolic role are inconsistent, possibly due to the opposing effects of AVP at different receptor subtypes, which regulation is still largely unknown. We performed this study to better investigate AVP metabolic role, and explore sex differences. We hypothesized that AVP would be positively associated with BMI, adiposity, and lean mass (acting as a signal of energy availability). We also predicted that relationships between AVP and body composition measures would differ by sex. We used the AVP area under the curve around a standardized meal to better capture repeated measures in response to food intake (that directly impacts energy availability). This also allowed to avoid the possible risk of fluctuating AVP levels due to possible pulsatile secretion. (more…)
Author Interviews, Cancer Research, Hematology, Leukemia / 15.06.2023

Medical Research Interview: Dr. Daniel Thomas MD PhD FRACP FRCPA Program Leader, Blood Cancer Precision Medicine Theme at the South Australia Health Medical Research Institute Clinical Hematologist, Royal Adelaide Hospital Associate Professor, Adelaide Medical School, The University of Adelaide MedicalResearch.com: What is the background for this study? Would you briefly describe the condition of CMML? Response: Chronic myelomonocytic leukemia (CMML) is a rare, but increasingly frequent, clonal stem cell disorder that results in hyperproliferation of inflammatory monocytes, a form of white blood cells. It features both myelodysplasia and myeloproliferation. CMML is most often found in older adults and leads to anemia, decreased quality of life, and an increased risk of acute myeloid leukemia (AML). Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a cytokine that stimulates production, growth, differentiation, activation, and function of myeloid cells (monocytes, neutrophils, and eosinophils). In the presence of RAS-pathway mutations, a greater sensitivity to GM-CSF contributes to the hyperproliferation of myelocytes in myelodysplastic leukemias such as CMML, juvenile myelomonocytic leukemia (JMML), and acute myeloid leukemia (AML).  In CMML, greater sensitivity to GM-CSF stimulates excessive monocytic precursor proliferation. The PREACH-M Trial, which stands for PREcision Approach to CHronic Myelomonocytic Leukemia, assesses the efficacy of lenzilumab in addition to azacitidine in treatment-naïve CMML participants with RAS-pathway mutations (KRAS, NRAS, CBL) and separately high dose ascorbate in participants with TET2 mutations who do not have RAS-pathway mutations. The study is currently underway and actively enrolling.  It is being conducted and funded by the South Australian Health and Medical Research Institute (SAHMRI).  (more…)
Alzheimer's - Dementia, Author Interviews, Genetic Research / 14.06.2023

MedicalResearch.com Interview with: Alexandra M Whiteley PhD Department of Biochemistry University of Colorado Boulder Boulder, Colorado MedicalResearch.com: What is the background for this study? Response: My laboratory was interested in understanding how UBQLN2 maintains cellular health. Ubiquilins facilitate protein degradation, but the precise proteins that they help to break down were not well understood. UBQLN2 is of particular interest because mutations in the UBQLN2 gene lead to a familial form of ALS. This project, which was published in eLife this year, stems from work that was published when I was a postdoctoral researcher at Harvard Medical School, where we found a link between UBQLN2 and the virus-like protein PEG10. Now at the University of Colorado, Boulder, my laboratory has focused on trying to understand this connection between the two proteins, and how PEG10 could contribute to ALS. (more…)
ASCO, Author Interviews, Cancer Research, Colon Cancer, Red Meat / 13.06.2023

MedicalResearch.com Interview with: Dr. Suneel Kamath MD Gastrointestinal Oncologist Cleveland Clinic Senior Author on this research       MedicalResearch.com: What is the background for this study? Response: Colorectal cancer rates in young people under age 50 are skyrocketing and have been for the last 3-4 decades. We really don’t understand why because most cases (probably around 70%) are not genetic or hereditary, just random, unfortunate events. We suspect that it is some exposure(s) like excess consumption of red meat, processed foods, sugar-sweetened beverages, excess antibiotic use altering the microbiome, rising incidence of obesity or some other factors. We really don’t know why yet. Our study used a technology called metabolomics, the study of breakdown products and production building blocks for our bodies, to look for differences in colorectal cancer in young people versus people that are older that developed colorectal cancer. Because metabolomics measures how each individual interacts with the exposures in our environment like diet, air quality, etc., it is a way to bridge the gap between our nature (determined by genetics) and nurture (determined by our exposures).

Author Interviews, Biomarkers, Nature, Prostate Cancer, UCSF / 12.06.2023

MedicalResearch.com Interview with: Rebecca E. Graff, ScD Assistant Professor University of California, San Francisco Department of Epidemiology & Biostatistics Mission Hall: Global Health & Clinical Sciences Building San Francisco, CA 94158 MedicalResearch.com: What is the background for this study? Response: PSA screening for prostate cancer has long been controversial. While it does seem to reduce mortality attributable to prostate cancer, it also results in the diagnosis of many cancers that never otherwise would have presented symptomatically. In addition, PSA levels are affected by factors other than prostate tumors (e.g., age, prostatic inflammation, and genetics), such that men with high PSA values are often referred for biopsy but do not end up having cancer. We hypothesized that accounting for the genetic component of PSA could yield adjusted values that better distinguish who should get a prostate biopsy. (more…)
Author Interviews, Columbia, Rheumatology / 06.06.2023

MedicalResearch.com Interview with: W. Benjamin Nowell PhD Director of Patient-Centered Research at Global Healthy Living Foundation Columbia University in the City of New York New York, New York MedicalResearch.com: What is the background for this study? Response: Given that lab tests are an important part of rheumatoid arthritis (RA) diagnosis and monitoring, people living with the condition want and need to understand their lab results –also known as blood work – for patient-centered shared decision making about treatment. The presentation titled, “Patient Perceptions of Rheumatoid Arthritis Blood Work and Utility of a Test Predicting Response to New Medication: A Cross-sectional Survey in the ArthritisPower,” presented at the 76th EULAR European Congress of Rheumatology (June 2, 2023 in Milan, Italy) includes results from a recent ArthritisPower survey (n=405) that asked patients to share their perceptions about RA bloodwork, reasons their doctor orders these tests, and how results are used.

ASCO, Author Interviews, Cancer Research, Genetic Research, JAMA, Race/Ethnic Diversity, Stanford / 06.06.2023

MedicalResearch.com Interview with: Allison W. Kurian, M.D., M.Sc. Professor of Medicine and of Epidemiology and Population Health Associate Chief, Division of Oncology Co-Leader, Population Sciences Program, Stanford Cancer Institute Director, Women’s Clinical Cancer Genetics Program Stanford University School of Medicine Stanford, CA 94305-5405 MedicalResearch.com: What is the background for this study? What types of cancers were in the study? Response: Genetic testing for cancer risk is increasingly important after a cancer diagnosis, to inform use of targeted therapies, secondary cancer prevention approaches and cascade genetic testing of family members. However, very little is known about how genetic testing is used after a cancer diagnosis at the population level. We leveraged a very large population-based data resource, the Surveillance, Epidemiology and End Results (SEER) cancer registries of the states of California and Georgia, and linked data from these registries to clinical genetic testing results provided by the four major laboratories that provide such testing. We used this linked registry-genetic testing dataset to study adults (age >=20 years) diagnosed with all types of cancer in the states of Georgia and California from 2013-2019. (more…)
ASCO, Author Interviews, Cancer Research, Lung Cancer, University of Pennsylvania / 05.06.2023

MedicalResearch.com Interview with: Lova L. Sun, MD, MSCE Medical Oncology Assistant Professor of Medicine Hospital of the University of Pennsylvania MedicalResearch.com: What is the background for this study? What are the main findings? Response: An common clinical question for patients with metastatic non-small cell lung cancer with long-term response to immunotherapy-based treatment is how long to continue treatment. The major clinical trials stopped immunotherapy at a maximum of 2 years, but in clinical practice many patients and clinicians continue treatment beyond this time point. We conducted a retrospective study of lung cancer patients across the US with long-term response to immunotherapy, to compare survival between those who stopped treatment at 2 years vs those who continued beyond 2 years. We found that there was no statistically significant difference in survival between the two groups. (more…)
Alzheimer's - Dementia, Author Interviews, Biomarkers, University of Pittsburgh / 31.05.2023

MedicalResearch.com Interview with: Bruna Bellaver PhD Postdoctoral associate Department of Psychiatry University of Pittsburgh Tharick Pascoal, MD, Ph.D. Neurologist and assistant professor of Neurology and Psychiatry University of Pittsburgh School of Medicine. MedicalResearch.com: What is the background for this study? Response: Amyloid-β (Aβ) deposition is considered one of the markers of Alzheimer’s disease pathology in the brain. The sequential order of this cascade includes the development of tau pathology and consequent cognitive decline. However, many people with Aβ deposition in the brain do not progress in the disease, suggesting that other biological processes are playing a role in these pathological events. In vitro evidence suggests that reactive astrocytes unleash Aβ effects in pathological tau phosphorylation. We found that, in cognitively healthy individuals, Aβ is associated with tau pathology only in individuals with increased astrocyte reactivity. (more…)
Author Interviews, Lifestyle & Health, Mental Health Research, Sleep Disorders / 30.05.2023

MedicalResearch.com Interview with: Joanna Gorgol PhD Student University of Warsaw MedicalResearch.com: What is the background for this study? Response: People differ in the time when they prefer to wake up and fall asleep: some people prefer going to bed and waking up early, while others prefer later hours. Most of the population is somewhere between them. Research indicates that being a morning person is related to reporting higher satisfaction with life and conscientiousness. Studies also show the associations between being religious and having higher life satisfaction and conscientiousness. It seems that religiosity might mediate the relationship between morningness and higher life satisfaction. To better understand these associations we conducted two questionnaire-based studies of Polish adults, one with 500 participants and the other with 728 participants. All participants completed questionnaires measuring their chronotype, satisfaction with life, personality traits, and religiosity (more…)
Anemia, Author Interviews, Diabetes, Kidney Disease, NEJM / 30.05.2023

MedicalResearch.com Interview with: Prof. Heerspink Prof. Hiddo Lambers Heerspink, PhD PHARMD Department of Clinical Pharmacy and Pharmacology University Medical Center Groningen Groningen

MedicalResearch.com: What is the background for this study? What is dapagliflozin primarily indicated for?   Response: Dapagliflozin is a sodium glucose cotransporter 2 (SGLT2) inhibitor. The multinational, double-blinded, randomized, placebo-controlled, DAPA-CKD trial demonstrated the kidney and cardiovascular benefits of dapagliflozin in 4304 patients with chronic kidney disease (CKD) with and without type 2 diabetes (T2D). Based on the results of this and other trials, current guidelines recommend use of SGLT2 inhibitors in patients with CKD, T2D, or heart failure. Anemia is common among patients with CKD and is associated with worse clinical outcomes. Previous studies showed that SGLT2 inhibitors increase hemoglobin and hematocrit levels, but data are lacking in patients with CKD with and without T2D. In this post-hoc analysis of DAPA-CKD, we assessed the effect of dapagliflozin versus placebo on the correction and prevention of anemia in this population. (more…)
