Author Interviews, Genetic Research, Heart Disease / 04.08.2022

MedicalResearch.com Interview with: Christine Seidman, MD Thomas W. Smith Professor of Medicine and Genetics Director, CV Genetics Center Brigham and Women’s Hospital Harvard Medical School Dept of Genetics Boston, MA 02115  MedicalResearch.com:  What is the background for this study?    Response: Heart failure is a common and incurable disorder that is known to arise from many different underlying causes.  By exploiting a new technology, single nuclear transcriptional analyses, we aimed to define molecular profiles in human hearts tissues that were obtained from patients with different genetic and non-genetic causes of heart failure. Our goal was to determine if there were distinctive signatures that could provide new opportunities to develop precise treatments, based on the specific cause of heart failure. (more…)
Author Interviews, COVID -19 Coronavirus, JAMA / 03.08.2022

MedicalResearch.com Interview with: Lisa A. Cosimi, MD Division of Infectious Diseases Brigham and Women’s Hospital Boston, Massachusetts  MedicalResearch.com:  What is the background for this study?  Response: Response: Current CDC COVID-19 isolation guidance allows for ending isolation after day 5 for non-immunocompromised individuals if they are afebrile and with improving symptoms, or if the individual is asymptomatic from the start. It has been proposed that rapid antigen tests (RATs) may assist in determining when individuals are no longer infectious. Specifically, a negative test would be potentially reassuring for an individual not being transmissible, while a positive test could be suggestive of continued infectiousness.  However, there is little data about use of RATs in this particular setting and how they may correlate with ongoing risk of transmission as they were developed to be used during the initial diagnosis of infection, not in the later phase.

Author Interviews, Emergency Care, JAMA / 03.08.2022

MedicalResearch.com Interview with: John A. Staples, MD, FRCPC, MPH Academic General Internist Vancouver General Hospital Clinical Assistant Professor at UBC MedicalResearch.com:  What is the background for this study?    Response: As a hospital-based general internist, I often see patients in the emergency department after an episode of syncope. Syncope is a medical term for suddenly losing consciousness (the public generally knows this as “fainting”). As you can imagine, fainting out of the blue can be very unnerving. Patients and clinicians worry that it may happen again and wonder whether it’s safe to drive. The first time I was asked this question, I remember scouring the research literature for an answer and not finding any robust evidence to guide my advice to patients. (more…)
Author Interviews, COVID -19 Coronavirus, Vaccine Studies / 02.08.2022

MedicalResearch.com Interview with: Dr Emma Wall Senior Clinical Research Fellow, UCLH-Crick Legacy study Consultant Infectious Diseases UCLH MedicalResearch.com:  What is the background for this study?  Response: Since April 2022, both the UK and US have changed their COVID-19 isolation and testing policies. The impact these changes in the guidance and vaccination on community-acquired COVID-19 caused by recent SARS-CoV-2 variants of concern (VOC) has not been fully tested, including infections with BA.2. We aimed to characterise both symptoms and viral loads over the course of COVID-19 infection in otherwise-healthy, vaccinated, non-hospitalised adults, to assess whether current guidance remains justified. All participants were included in the UCLH-Crick Legacy study, a prospective, observational cohort study of otherwise healthy adults who have been taking part in regular workplace testing for SARS-CoV-2 in London We sent swabs by same-day courier every other day to all adults who reported a positive PCR or lateral flow test to the study team up to day 10 after the start of each infection. We confirmed which variant caused the infection by PCR and sequencing. All participants completed linked symptom diaries. We compared symptoms and changes in the amount of virus detected in the nose and throat during infection between study participants reporting COVID-19 caused by VOCs Delta and Omicron BA.1 and BA.2. We then analysed how many of our participants would meet current UK/US isolation guidelines. (more…)

Aging, Author Interviews, Environmental Risks, Nature / 30.07.2022

MedicalResearch.com Interview with: Dr. Jaga Giebultowicz Professor Emeritus, Department of Integrative Biology Oregon State University Corvallis, OR 97331 MedicalResearch.com:  What is the background for this study?  Where is blue light commonly found? Response: Our study in short-lived model organism Drosophila revealed that cumulative, long-term exposure to blue light impacts brain function, accelerates the aging process and significantly shortens lifespan compared to flies maintained in constant darkness or in white light with blue wavelengths blocked. Blue light is predominantly produced by the light-emitting diodes (LEDs); it appears white due to the addition of yellow fluorescent powder which is activated by blue light. LEDs has become a main source of  display screens (phones, laptops, desktops, TV),  and ambient lights. Indeed, humans have become awash in LEDs for most of their waking hours. (more…)
Addiction, Author Interviews / 30.07.2022

MedicalResearch.com Interview with: Bryan Roth, MD, PhD Michael Hooker Distinguished Professor Pharmacology Director, NIMH Psychoactive Drug Screening Program Eshelman School of Pharmacy Gavin P. Schmitz Department of Pharmacology University of North Carolina at Chapel Hill School of Medicine Chapel Hill, North Carolina   Department of Pharmacology, School of Medicine University of North Carolina at Chapel Hill Chapel Hill, North Carolina MedicalResearch.com:  What is the background for this study?  What are the main findings?  Response: There is undoubtably a lot of enthusiasm for psychedelics as therapeutic tools right now both in research and more broadly; however, there are still so many questions that need to be answered. It has been established that SNPs are clinically relevant when considering how patients may respond to various atypical antipsychotic drugs, so we wanted to see if they also could impact psychedelic assisted treatment strategies. What we found is that genetics do matter; namely, our results indicate that patients with different genes will react differently to psychedelics. (more…)
Author Interviews, JAMA, Pediatrics, Weight Research / 28.07.2022

MedicalResearch.com Interview with: Amanda Staiano, PhD Associate Professor Director, Pediatric Obesity and Health Behavior Laboratory Pennington Biomedical Research Center Baton Rouge, LA MedicalResearch.com:  What are the main findings? Response: The U.S. government funds the National Health and Nutrition Examination Survey (NHANES), which is an ongoing surveillance study on the health and nutritional status of people living in the U.S. What is special about NHANES is it’s designed to be nationally representative and it uses objective measurements, so we’re more confident that this accurately reflects the health of the country. For this paper, we looked at the most recently released data to see how many children in the U.S. have obesity, meaning they’re above the 95th percentile for height and weight based on their age and sex. We extracted data from 2011 to 2020, which includes nearly 15,000 children and adolescents and is the most recently available data prior to the March 2020 COVID-19 shutdown when NHANES paused.

MedicalResearch.com Interview with: Clare Jensen O’Haire Research Team Center for the Human-Animal Bond Purdue University College of Veterinary Medicine MedicalResearch.com:  What is the background for this study?  Response: Service dogs for PTSD are becoming more common and the evidence shows they can help improve mental health and quality of life for many veterans with PTSD. However, some veterans benefit more than others. Our research goal was to ask for the very first time: Why? (more…)
Author Interviews, Brigham & Women's - Harvard, Endocrinology, Hip Fractures, NEJM, Osteoporosis, Vitamin D / 27.07.2022

MedicalResearch.com Interview with: Meryl S. LeBoff, MD Chief, Calcium and Bone SectionDirector of the Skeletal Health and Osteoporosis CenterDirector, Bone Density UnitDistinguished Chair in Skeletal Health and Osteoporosis Professor of Medicine, Harvard Medical School Endocrinology, Diabetes and HypertensionWomen's Health Brigham And Women's Hospital JoAnn E. Manson, MD, DrPH Professor, Epidemiology, Harvard T.H. Chan School Of Public Health Michael and Lee Bell Professor of Women's Health, Medicine, Harvard Medical School Chief, Preventive Medicine, Brigham And Women's Hospital Co-Director, Womens Health, Brigham And Women's Hospital   MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: Osteoporosis is a major public health problem. Although supplemental vitamin D has been widely used to reduce the risk of fractures in the general population, studies of the effects of vitamin D on fractures, the most important bone health outcome, have been conflicting. Randomized controlled trials, the highest quality studies, from around the world have shown benefit, no effect, or even harm of supplemental vitamin D on risk of fractures. Some of the trials used bolus dosing, had small samples sizes or short study duration, and co-administered calcium. No large RCTS of this scale tested whether daily supplemental vitamin D (without co-administration with calcium) prevented fractures in the US population. To fill these knowledge gaps, we tested the hypothesis in this ancillary study to VITAL, whether daily supplemental vitamin D3 reduced the risk of incident total, non-spine and hip fractures in women and men in the US.

OBGYNE / 27.07.2022

Becoming a parent is an incredibly daunting task, it can put a lot of strain on individuals and relationships. This doesn’t necessarily have to be between the couples, as extended families might feel entitled to push new parents and make them feel bad for not raising their child in a certain way. Young parent life can be seen as something fun, a new experience. But there are a lot of new things that are difficult to cope with. Stress boils, issues with post-partum depression become damaging and of course, nothing is as plain sailing as it might seem. That’s quite a list, so with that in mind – here are some of the main things that all soon-to-be parents should be aware of.

Stress

pregnancy pregnantStress might be something that isn’t new to you. Stress can come from a lot of things. You might have problems financially, or you might be struggling with a lot of sleep deprivation, especially if you are the pregnant person in your relationship. People might joke about you enjoying the sleep that you are getting now because it won’t last forever, but the chances are, you aren’t getting nearly enough sleep as it is already. This is a period filled with highs and lows, especially if the due date is coming around the corner and you are struggling with making sure everything is ready on time. Stress is damaging to the baby too, so if your pregnant partner isn’t your top priority (which it absolutely should be through all of the pregnancy and newborn stages) you should switch it around so they are at the top of your list whenever they need anything.

Author Interviews, Cancer Research, Nutrition / 26.07.2022

MedicalResearch.com Interview with: Prof. John C. Mathers PhD Director, Human Nutrition Research Centre Director, Centre for Healthier Lives Population Health Sciences Institute Newcastle University Newcastle on Tyne UK MedicalResearch.com:  What is the background for this study?   Response: My colleagues and I have had a long-term interest in carrying out studies in people with hereditary cancer as a model for cancer in the general population. Here we studied people with Lynch syndrome who have an inherited defect in one of the genes encoding the DNA mismatch repair system. Because of this, they accumulate DNA damage faster than the general population and are prone to early cancers at several sites around the body. In the CAPP2 Study, we randomised almost 1000 people with Lynch syndrome to either resistant starch or to an ordinary corn-starch placebo. (more…)
Author Interviews, Heart Disease, Salt-Sodium / 20.07.2022

MedicalResearch.com Interview with Weihao Liang on behalf of Professor Chen Liu Department of Cardiology, Sun Yat-sen University First Affiliated Hospital Guangzhou, Guangdong, China MedicalResearch.com:  What is the background for this study?    Response: -Salt intake restriction is frequently recommended in heart failure guidelines, but is restricting salt intake to "as least as possible" appropriate? Evidence is lacking. Besides, the effect of salt restriction on patients with heart failure with preserved ejection fraction isn’t clear as they have often been excluded from relevant studies. (more…)

Author Interviews, Dermatology, Infections / 15.07.2022

MedicalResearch.com Interview with: Dr Dilip Kachhawa, MD Department of Skin & Venereal Disease Dr Sampurnanand Medical College Jodhpur, Rajasthan, India MedicalResearch.com:  What are the main findings? Response: Molluscum Contagiosum (MC) is an infection caused by molluscipoxvirus. It is difficult to study since the virus only survives in human skin, and therefore there isn’t an animal or cell model to study potential treatments. Molluscum lesions appear as raised, domed shaped skin-colored lesions and can occur anywhere on the body but are most common on the face, neck, arms, legs, and abdomen. Sometimes there are few lesions, but clusters of several lesions can appear. Children are the most likely to get molluscum, and the virus is highly contagious, transmitted by direct contact with infected skin or contaminated objects, like towels, linens and toys. Scratching can cause autoinoculation which is when a person reinfects themself. MC is very common, impacting an estimated 6 million adults and mostly children in the US each year. In 2010, there was an estimated 122 million cases worldwide. It occurs primarily in humid and warm climates, and transmission via swimming pools and bathtubs may be possible. Therefore, molluscum is often called “water warts.” Many physicians may take a “watch and wait” approach since the virus may clear on its own. However, it can take months to up to 5 years for some to experience complete clearance, In the meantime, the person is still highly contagious and may spread the virus to others, particularly children. Lesions can be bothersome, causing itching and sometimes a secondary infection. There is also a psychosocial component. In a recent study, 1 in 10 children with molluscum experienced a major quality of life issue. Berdazimer Gel, 10.3% is a potential first-in-class topical controlled-nitric oxide releasing medication containing Berdazimer (sodium), a new chemical entity, and the active ingredient in berdazimer gel 10.3%. The mechanism of action of berdazimer in the treatment of molluscum is unknown, but in vitro lab studies show that the nitric oxide, released when berdazimer is combined with a hydrogel, may impede viral replication and perhaps help body’s natural immune response against molluscum.

Author Interviews, Health Care Systems, JAMA / 12.07.2022

MedicalResearch.com Interview with: Dr. Joanna JiangJoanna Jiang, PhD Agency for Healthcare Research and Quality Rockville, Maryland MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: Over the last decade we have seen two trends occurring to rural hospitals – closures and mergers. A hospital in financial distress could likely face closure. But if the hospital affiliates with a multihospital system, it may have access to resources from the system that help shelter the hospital from closure. That is exactly what we found in this study. System affiliation was associated with a lower risk of closure for financially distressed hospitals. However, among hospitals that were financially stable, system affiliation was associated with a higher risk of closure. This is somewhat puzzling and needs further study to better understand the reason for closure. (more…)
Author Interviews, Environmental Risks, Hepatitis - Liver Disease, JAMA / 06.07.2022

MedicalResearch.com Interview with: Dania Valvi, MD MPH PhD Assistant Professor Department of Environmental Medicine and Public Health Co-Director, MS in Epidemiology Icahn School of Medicine at Mount Sinai Email: [email protected] MedicalResearch.com:  What is the background for this study?    Response: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in children in the U.S., Europe and other world regions, currently affecting 1 in every 10 children, and 1 in every 3 children with obesity in the U.S. The rate of pediatric NAFLD has more than doubled in recent decades following the epidemic rates also noted for childhood obesity. There is increasing interest in the role that environmental chemical exposures may play in NAFLD etiology, since several animal studies have shown that prenatal exposures to endocrine-disrupting chemicals (EDCs) cause liver injury and damage; but, until now, the potential effects of prenatal EDC mixture exposures in pediatric NAFLD had not been studied.

Author Interviews, Education, JAMA, Pharmaceutical Companies / 06.07.2022

MedicalResearch.com Interview with: SooYoung VanDeMark, MBS Geisinger Commonwealth School of Medicine Scranton, Pennsylvania MedicalResearch.com:  What is the background for this study?   Response: Health care providers utilize subscription-based, point-of-care databases such as DynaMed and UpToDate to provide clinical care guidance and remain current on the latest evidence-based findings. Both of these websites maintain this content through a cadre of physician contributors who write and edit articles for these sites. These physician contributors are required to self-report any conflicts of interest (COI) as outlined by the respective policies on each website. However, prior COI research into similarly self-regulated areas, such as medical and pharmacology textbooks, and clinical practice guidelines, has found both appreciable potential COI and inconsistencies between self-reported and industry mandated disclosures (1-3). This study (4) explored the accuracy of physician contributors to DynaMed and UpToDate by comparing their self-reported disclosure status with the financial remunerations they received from the healthcare industry (e.g., pharmaceutical companies) as reported to the U.S. Centers for Medicare and Medicaid Services’ Open Payments database. Physician contributors who reported “nothing to disclose” on their respective article topic but had an entry on Open Payments for having received money from industry, were classified as discordant and, thus, as having the potential for a COI. Additionally, total remuneration, gender, and payment category were investigated more in depth for each database. (more…)
Allergies, Author Interviews, JAMA, Pediatrics / 06.07.2022

MedicalResearch.com Interview with: Victoria Soriano PhD Research Assistant/Officer, Population Allergy University of Melbourne   MedicalResearch.com:  What is the background for this study?  Response: Peanut allergy is one of the most common childhood food allergies, and children rarely grow out of it. The only proven way to prevent peanut allergy is to give infants age-appropriate peanut products in the first year of life. We previously showed there was a dramatic increase in peanut introduction from 2007-11 to 2018-19, following changes to infant feeding guidelines. We wanted to know if earlier peanut introduction would reduce peanut allergy in the general population (in Melbourne, Australia). (more…)
Author Interviews, Infections, NIH / 30.06.2022

MedicalResearch.com Interview with: Nihal Altan-Bonnet, Ph.D. Chief of the Laboratory of Host-Pathogen Dynamics NHLBI  MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: Enteric viruses such as norovirus, rotavirus and astrovirus are responsible for nearly 1.5 billion global infections per year resulting in gastrointestinal illnesses and sometimes leading to death in the very young, in the elderly and in the immunocompromised. These viruses have been thought to traditionally infect and replicate only in the intestines, then shed into feces and transmit to others via the oral-fecal route (e.g. through ingestion of fecal contaminated food items). Our findings reported in Nature, using animal models of norovirus, rotavirus and astrovirus infection, challenge this traditional view and reveal that these viruses can also replicate robustly in salivary glands, be shed into saliva in large quantities and transmit through saliva to other animals. In particular we also show infected infants can transmit these viruses to their mothers mammary glands via suckling and this leads to both an infection in their mothers mammary glands but also a rapid immune response by the mother resulting in a surge in her milk antibodies. These milk antibodies may play a role in fighting the infection in their infants .  (more…)
Author Interviews, Brigham & Women's - Harvard, Heart Disease, JAMA, Lung Cancer, Supplements, USPSTF / 30.06.2022

MedicalResearch.com Interview with: Michael J. Barry, M.D Director of the Informed Medical Decisions Program Health Decision Sciences Center Massachusetts General Hospital. Professor of medicine at Harvard Medical School Dr. Barry was appointed as Vice Chair of USPSTF in March 2021. He previously served as a member from January 2017 through December 2020.   MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: The Task Force looked at the use of vitamin and mineral supplementation specifically for the prevention of heart disease, stroke, and cancer. We found that there is not enough evidence to recommend for or against taking multivitamin supplements, nor the use of single or paired nutrient supplements, to prevent these conditions. However, we do know that you should not take vitamin E or beta-carotene for this purpose. (more…)

MedicalResearch.com Interview with: Emanuela Taioli, MD, PhD Director, Institute for Translational Epidemiology Professor, Population Health Science and Policy Professor, Thoracic Surgery Icahn School of Medicine at Mount Sinai New York, NY MedicalResearch.com:  What is the background for this study?  Response: NYC experienced a halt on all elective care from March 22 to June 8, 2020, provoking reduced cancer screening rates, and delayed cancer care and treatment. We wanted to quantify the effect of the “pause” on cancer stage at diagnosis using lung cancer as an example of a condition where early diagnosis can dramatically modify survival. (more…)
Author Interviews, Brigham & Women's - Harvard, Neurology, Parkinson's / 21.06.2022

MedicalResearch.com Interview with: Vikram Khurana, MD, PhD Chief of the Division of Movement Disorders Department of Neurology Brigham and Harvard Medical School Principal investigator, Ann Romney Center for Neurologic Diseases at the Brigham MedicalResearch.com:  What is the background for this study?   Response: Proteins abnormally accumulate in brain cells (neurons and glial cells) in all neurodegenerative diseases. In Parkinson’s disease and related disorders, the key protein that accumulates and aggregates is called “alpha-synuclein.” Presumably, when a protein like alpha-synuclein abnormally folds and aggregates, the abnormal form of the protein can become toxic to the neuron, eventually leading to cell death. Equally, the protein may no longer be able to carry out its normal function. This begs the question – what does alpha synuclein actually do? Most evidence to date points to alpha-synuclein being involved in the transport of other proteins and chemicals around the cell, by closely associating with vesicles that are small circular containers enclosed by fat (“lipid) membranes. But alpha-synuclein is not just found associated with these vesicle membrane. It is found away from the membrane and it’s been unclear what it does there. (more…)

Author Interviews, Critical Care - Intensive Care - ICUs, NEJM, Vitamin C / 15.06.2022

MedicalResearch.com Interview with: François Lamontagne MD MSc (pharmacology) MSc (CEB) Professor of Medicine at the Université de Sherbrooke Endowed research chair on patient-centred research Dr. Neill Adhikari MDCM, M.Sc. Sunnybrook Research Institute and University of Toronto Toronto, Canada MedicalResearch.com:  What is the background for this study?  Response: The use of intravenous vitamin C for sepsis has been a hot topic for a few years. It was biologically plausible that vitamin C could reduce organ injury and death by scavenging reactive oxygen species and modulating the immune response to sepsis. It also seemed like an intervention that would be reasonably easy to administer globally should it prove beneficial. On the other hand, no intervention is benign and every aspect of health care should be rigorously studied. Regarding vitamin C, there were strongly held opinions in both camps and this motivated us to design and conduct the LOVIT trial. (more…)
