Annals Internal Medicine, Author Interviews, Esophageal, Gastrointestinal Disease / 20.10.2020

MedicalResearch.com Interview with: 加藤元嗣　Mototsugu KATO MD PhD 院長  独立行政法人国立病院機構函館病院 Director, National Hospital Organization Hakodate National Hospita MedicalResearch.com: What is the background for this study? Response: The primary goal of upper gastrointestinal (GI) endoscopic examination is to detect neoplastic lesions in the pharynx, esophagus, and stomach. However, early-stage lesions may frequently be overlooked by conventional white light endoscopy. Since the recent launch of image-enhanced endoscopy, many studies have evaluated its efficacy in diagnosing upper GI neoplasms as well. Linked color imaging (LCI )emphasizes the difference in color to make it easier to detect neoplastic lesions. The aim of this trial is to compare the performance of LCI with white light imaging in detecting upper GI tract neoplastic lesions.  (more…)
Author Interviews, HIV, Lancet / 18.10.2020

MedicalResearch.com Interview with: Steve Kanters, PhD MSc Rain City AnalyticsPresident and Lead Analyst RainCity Analytics School of Population and Public Health, University of British Columbia Vancouver, British Columbia, Canada MedicalResearch.com: What is the background for this study? Response: A watershed moment for the fight against HIV was the antiretroviral treatment (ART) scale-up that made HIV treatments available around the world. While HIV activism led to its initiation, two key ingredients to the ART scale-up were the advent of a once-daily single-pill HIV treatment and the creation of the World Health Organization (WHO) clinical guidelines for treatment and prevention of HIV. The HIV treatment in question combines three drugs in a single pill and centers around a drug called efavirenz. The WHO guidelines use a public health framework, which is to say that it uses a treatment algorithm that is both equitable and simple enough to allow some task-shifting to less specialized workers. As such, the guidelines suggest a single preferred treatment for people initiating HIV treatment. While resource rich countries can use a personalized medicine approach, many settings where HIV is endemic cannot. In 2015, our review found strong evidence that a newer HIV drug, called dolutegravir, was better than efavirenz in respect to efficacy, tolerability and safety; however, there was not enough evidence to support its use in key populations, such as people with HIV-tuberculosis co-infections and pregnant women. For this and other reasons, the WHO could not recommend its use as the preferred treatment at initiation. Since then, we have continued to dynamically assess the evidence to determine the best treatment to have as the preferred ART for first-time HIV treatment. This is the culmination of 6 years of work and its findings have helped the WHO change its recommended preferred first-line therapy from an efavirenz-based ART to a dolutegravir-based ART.  (more…)
Author Interviews, COVID -19 Coronavirus, Gender Differences, PNAS / 18.10.2020

MedicalResearch.com Interview with: Paola Profeta, PhD Professor of Public Economics, Department of Social and Political Sciences Bocconi University Director, Msc Politics and Policy Analysis, Bocconi University Coordinator, Dondena Gender Initiative, Dondena Research Center President, European Public Choice Society MedicalResearch.com: What is the background for this study? What are the main findings? Response: We interview more than 20000 men and women in 8 OECD countries in two periods during the lockdown. Using two waves from 8 OECD countries, we find that women are more likely to perceive the pandemic as a very serious health problem, to agree with restraining measures and to comply with public health rules, such as using facemasks. This gender differences are less strong for married individuals and for individuals who have been directly exposed to COVID, for instance by knowing someone who was infected.  (more…)
Author Interviews, BMJ, Surgical Research / 15.10.2020

MedicalResearch.com Interview with: Sebastian Straube, BM BCh, MA (Oxon), DPhil Professor and Director, Division of Preventive Medicine, Department of Medicine University of Alberta Zone Section Chief, Occupational Medicine Edmonton Zone, Alberta Health Services Director, Foundation Course in Occupational Medicine surgery-aerosols-covid-19MedicalResearch.com: What is the background for this study?   Response: In view of the COVID-19 pandemic, medical procedures that generate aerosols require a higher grade of personal protective equipment, typically including filtering facepiece respirators (e.g. N95 masks). We wanted to know which procedures were aerosol-generating and would require such enhanced precautions. MedicalResearch.com: How did you approach that question? Response: We conducted a systematic review of the literature and aimed to find those procedures for which there is widespread agreement that they are aerosol-generating. We assembled a team of researchers with expertise in the subject matter as well as in systematic review methodology, and we searched widely for relevant guidelines, policy documents, and academic papers.

Author Interviews, Pediatrics, PNAS, Weight Research, Wistar / 15.10.2020

MedicalResearch.com Interview with: Kristina M. Rapuano PhD, Postdoctoral Research Fellow BJ Casey, PhD, Professor of Psychology at Yale University Richard Watts PhD Technical Consultant Department of Psychology Yale University, New Haven, CT MedicalResearch.com: What is the background for this study? Response: Around 35% of children and adolescents in the US are overweight or obese, dramatically increasing their likelihood of obesity as adults and the associated health risks. In our paper we use a novel MRI technique to investigate links between obesity and neurobiology in a large group of typically developing 9-10 year-olds. The data were acquired as part of the NIH-funded Adolescent Brain Cognitive DevelopmentSM (ABCD) study, which enrolled more than 11,000 children from across the US. We looked specifically at a reward-related region of the brain called the nucleus accumbens. Previous human studies have shown that healthy weight and obese children display different responses to food cues, for example adverts for unhealthy foods, in this region. Animal studies have also found that a high saturated fat (unhealthy) diet induces inflammation in the nucleus accumbens, and changes in behavior including sucrose-seeking. We wanted to investigate if we could use advanced MRI techniques to provide evidence of a similar effect in humans. (more…)

MedicalResearch.com Interview with: Roy S. Herbst, M.D., Ph.D. Ensign Professor of Medicine (Medical Oncology) and Professor of Pharmacology Chief of Medical Oncology Yale Cancer Center and Smilow Cancer Hospital Associate Cancer Center Director for Translational Research Yale Cancer Center  MedicalResearch.com: What is the background for this study? How does osimertinib differ from prior versions of EGFR-TKI Inhibitors? o   ADAURA is a randomized, double-blinded, global and placebo-controlled Phase III trial in the adjuvant treatment of 682 patients with Stage IB, II, and IIIA EGFRm NSCLC following complete tumor resection and adjuvant chemotherapy as indicated. Patients were treated with osimertinib 80 mg once-daily oral tablets or placebo for three years or until disease recurrence. The primary endpoint is disease free survival (DFS) in Stage II and IIIA patients, and a key secondary endpoint is DFS in Stage IB, II and IIIA patients. Osimertinib is not currently approved in the adjuvant setting in any country. o   Osimertinib is a third-generation, irreversible EGFR-TKI with clinical activity against central nervous system metastases. The results of the Phase III ADAURA trial of osimertinib demonstrate for the first time in a global trial that an EGFR inhibitor can change the course of early-stage EGFR-mutated lung cancer for patients. o   ADAURA results were first presented in May during the American Society of Clinical Oncology ASCO20 Virtual Scientific Program.

MedicalResearch.com Interview with: Ulrik Wisløff Professor and Head of CERG and K.G. Jebsen Centre for Exercise in Medicine of Circulation and Medical Imaging, Faculty of Medicine and Health Sciences NTNU-Norwegian University of Science and Technology Trondheim, Norway MedicalResearch.com: What is the background for this study? Response: The Generation 100 study followed more than 1500 women and men in their 70s for five years. The aim was to find out if exercise gives older adults a longer and healthier life, and we also compare the effect of moderate and high-intensity exercise. MedicalResearch.com: What are the main findings? Response: Overall survival was high in all three groups, compared to what’s expected in this age group. There was a clear trend towards greater survival in the high-intensity compared to the moderate intensity exercise group. High-intensity interval training also had the greatest effect on cardiorespiratory fitness and health-related quality of life. (more…)

MedicalResearch.com Interview with: Tsu-Shuan Wu University of California, San Francisco San Francisco, California MedicalResearch.com: What is the background for this study? What are the main findings? “Checking your phone and vaping as you do” by Alper Çuğun is licensed under CC BY 2.0 Response: The background for this study involves the associations of household rules and parental awareness with youth tobacco use using data from the Population Assessment Tobacco and Health Study. Health concerns regarding non-cigarette tobacco products, specifically e-cigarettes, have been on the rise. We wanted to explore whether parents are up to date with the trends of popular tobacco products today and what role they may play in youth tobacco cessation and prevention. The main findings of the study revealed that parents less often suspected their children’s tobacco use if their children reported using only e-cigarettes, and other non-cigarette tobacco products, when compared with cigarettes. Additionally, we found that youth who agreed with their parents that their home has strict rules for tobacco use were less likely to initiate of tobacco use compared to youth who had different understanding of the rules from their parents or youth from households with more permissive household rules.  (more…)
Author Interviews, Cannabis, JAMA, Tobacco Research / 07.10.2020

MedicalResearch.com Interview with: Isabella Lanza, PhD Associate Professor of Human Development California State University, Long Beach   MedicalResearch.com: What is the background for this study? What are the main findings? Response: This is the first study to examine both nicotine vaping and cannabis vaping trajectories across adolescence and young adulthood, which allowed us to assess whether poly-substance vaping is common among adolescents and young adults. Poly-substance vaping (nicotine and cannabis vaping) was reported among a significant proportion of participants in the study (25% were identified as poly-substance vapers). For those that either escalated to frequent nicotine vaping use in adolescence or initiated frequent nicotine vaping use in young adulthood, the probability of engaging in cannabis vaping was very high (85%+).    (more…)
Author Interviews, COVID -19 Coronavirus, Emory, NEJM, NIH, Vaccine Studies / 04.10.2020

MedicalResearch.com Interview with: Evan J. Anderson, MD Associate Professor of Medicine and Pediatrics Emory University School of Medicine MedicalResearch.com: What is the background for this study? Response: Older adults have suffered a disproportionate number of the hospitalizations and deaths due to COVID-19. A vaccine is clearly needed for older adults.  For a number of vaccines, the immune response and efficacy of vaccines decreases with increasing age. A prime example would be influenza and the need for high dose influenza vaccine in the elderly. We had previously conducted a Phase I study in 18 – 55 year old adults of mRNA-1273 vaccine – published in NEJM 2020 with Lisa Jackson as the lead author. This phase I study was expanded to include older adults in 2 separate cohorts (56 – 70, >70 years of age) and 2 different doses. (more…)
Author Interviews, Dermatology, JAMA, Parkinson's / 01.10.2020

MedicalResearch.com Interview with: Wenquan Zou, MD/PhD, Professor Department of Pathology Associate Director National Prion Disease Pathology Surveillance Center Case Western Reserve University School of Medicine Cleveland, Ohio 44106 MedicalResearch.com: What is the background for this study? Response: Parkinson’s disease (PD) is the second most common age-related neurodegenerative disorder. It is characterized by the accumulation of pathologically misfolded α-synuclein (αSynP) aggregates in the brain. Currently, a definite diagnosis relies on the detection of αSynP-containing Lewy bodies in the brain of PD patients. Development of a reliable and sensitive assay for αSynP in easily accessible peripheral tissue specimens is critical for early or differential diagnosis, determination of disease severity, and evaluation of therapeutic efficacy in clinical trials. Previous studies have revealed that the pathologically phosphorylated α-synuclein is detectable with traditional immunohistochemistry (IHC) and immunofluorescence (IF) microscopy but the sensitivity with IHC/IF is highly variable and inconsistent. Also the prion-like aggregation seeding activity of αSynP is detected in cerebrospinal fluid (CSF) of Parkinson’s disease patients with highly sensitive real-time quaking-induced conversion (RT-QuIC) and protein misfolding cyclic amplification assays (PMCA). But the lumbar puncture to collect CSF is more invasive compared to skin punch biopsy. (more…)

Alcohol, Author Interviews, Gender Differences, JAMA / 30.09.2020

MedicalResearch.com Interview with: Michael S. Pollard, Ph.D. Professor, Pardee RAND Graduate School Senior Sociologist RAND Corporation Santa Monica, CA 90407-2138 MedicalResearch.com: What is the background for this study? What are the main findings? Response: There are ample anecdotal jokes and stories about increased alcohol use during COVID-19 and stay-at-home orders. Our study provides robust longitudinal evidence that people drank more frequently, and for women in particular, more heavily, and with more negative consequences, during the initial stages of COVID-19 compared to their own behaviors from a year earlier (May/June 2020 compared to May/June 2019). Women’s alcohol consumption was most significantly changed, with a 17% increase in number of days drinking, and a 41% increase in days of binge drinking (when they had four or more drinks in a couple of hours). This means that, nationally, one in five women drank heavily one more day a month than the same time in 2019, on average. Women also reported a 39% increase in alcohol-related problems, such as “I took foolish risks” or “I failed to do what was expected of me” because of drinking alcohol. (more…)

MedicalResearch.com Interview with: Jason Nagata, MD, MSc Assistant Professor of Pediatrics University of California, San Francisco San Francisco, California  MedicalResearch.com: What is the background for this study? Response: Although prior research has identified disparities in migraine by race and sex, little was previously known about disparities in migraine by sexual orientation.  MedicalResearch.com: What are the main findings?  Response: In a national sample of nearly 10,000 adults in the USA, we found that nearly one third of lesbian, gay, and bisexual individuals have experienced a migraine. Overall, we found that lesbian, gay, or bisexual individuals had 58% higher odds of experiencing a migraine compared to heterosexual individuals. We also found that individuals who identified as mostly heterosexual but with some same-sex attractions were more likely to experience a migraine compared to those who identified as exclusively heterosexual.

MedicalResearch.com Interview with: Kimber L. Stanhope PhD RD Department of Molecular Biosciences School of Veterinary Medicine University of California Dr. Bettina Hieronimus PhD Institute of Child Nutrition Max Rubner-Institut, Federal Research Institute of Nutrition and Food Karlsruhe MedicalResearch.com: What is the background for this study?   Response: Sugar consumption is associated with increased body weight and other metabolic diseases. Fructose in particular seems to be detrimental to health as it causes higher increases in blood lipids compared to glucose. Our study assessed the effects of sugar consumption on cardiometabolic risk factors. We compared the effects of consuming glucose, two different doses of fructose or high fructose corn syrup (HFCS) with a non-caloric sweetener. Our subjects were healthy young individuals who drank three sweetened beverages per day over the course of two weeks. (more…)
Author Interviews, COVID -19 Coronavirus, Kidney Stones, Lancet, Stanford / 26.09.2020

MedicalResearch.com Interview with: Shuchi Anand M.D. M.S. Director of the Center for Tubulointerstitial Kidney Disease Stanford University MedicalResearch.com: What is the background for this study? Response: Seroprevalence (or presence of antibodies in response to SARS CoV-2) is considered by many experts to be the most complete to track the spread of COVID19 in communities. However seroprevalence studies are hard to conduct, because they require going into communities and underdoing random blood draws. Many people—especially racial and ethnic minorities, or people with underlying health conditions, or people with language barriers—may be hard to reach for these types of surveys. Plus outreach into communities is very difficult in light of the COVID19 pandemic. To mitigate this problem we worked with a random sample of 28,503 patients on hemodialysis, the vast majority of whom are covered by Medicare. They get their blood drawn monthly, as part of their routine care. Furthermore even though we used a random sample, we know that patients on dialysis are more likely to be racial and ethnic minorities, and more likely to come from disadvantaged backgrounds.  (more…)
Author Interviews, COVID -19 Coronavirus, FASEB, Genetic Research / 25.09.2020

MedicalResearch.com Interview with: David Gurwitz, PhD Associate Professor Department of Human Molecular Genetics and Biochemistry Sackler Faculty of Medicine Tel-Aviv University, Tel-Aviv Israel MedicalResearch.com: What is the background for this study? Response: We closely followed the news on COVID-19 epidemiology since it was declared a pandemic, and were puzzled by the low fatality rates reported in nearly all East Asian countries, even that clearly this was in part due to fast response; for example, Taiwan remains the best example for combatting the pandemic. My past research on serpins (serine protease inhibitors) made me wonder if ethnic differences in some of them are in part related to the relatively low COVID-19 morbidities and fatalities, as serine proteases, in particular TMPPRSS2, are strongly implicated in the SARS-CoV-2 respiratory track cell entry and infection. Additionally, serine proteases such as neutrophil elastase are highly implicated in inflammatory tissue damage. Guy Shapira, a graduate student of my colleague Professor Noam Shomron, examined mutation records in different ethnic groups for the entire human serpin gene family. He came up with the findings we report regarding a close correlation between national records of the frequencies of the two mutations PiZ and PiS, underlying alpha-1 antitrypsin deficiency, in 67 countries on the global scale, and the current COVID-19 fatalities in the same 67 countries.  (more…)
Author Interviews, Cannabis, JAMA, OBGYNE, Pediatrics / 25.09.2020

MedicalResearch.com Interview with: Sarah E. Paul, BA , Graduate Student and Ryan Bogdan, PhD, Associate Professor BRAIN Lab Washington University in St. Louis St. Louis, MO 63130 MedicalResearch.com: What is the background for this study? Sarah Paul: This study was motivated by several trends in cannabis use, its legal landscape, and people's perception of risk. As more states legalize recreational cannabis use, cannabis has become more accessible as well as more potent. Over the past couple of decades, the percentage of adolescents and adults who think that cannabis use is risky or harmful has fallen substantially. Cannabis dispensaries have been reported to actually recommend cannabis to pregnant women for the treatment of pregnancy-related nausea. And finally, between 2002/2003 and 2016/2017, the percentage of women reporting cannabis use during their pregnancies rose 106%. Given these trends and the mixed literature regarding the potential consequences associated with prenatal cannabis exposure, we aimed to comprehensively examine a range of outcomes in a large, representative sample while accounting for a host of important potentially confounding covariates.

Author Interviews, Brain Injury, Brigham & Women's - Harvard, JAMA / 25.09.2020

MedicalResearch.com Interview with: Maria Gabriela Figueiro Longo, MD, MSc Department of Radiology, Massachusetts General Hospital Harvard Medical School, Boston MedicalResearch.com: What is the background for this study? What are the main findings? Response: Transcranial low-level light therapy (3LT) has been shown to be effective in animal models of traumatic brain injury. Our goal was to assess the 3LT in humans with acute TBI. We tested (1) safety, and (2) any effect in the brain in a measurable way. We found positive results for both - there was no event adverse during the trial related to the 3LT; and we found some differences in the brain MRI diffusivity parameters in the patients who received light therapy compared to the sham group. The study was not powered for clinical evaluation, although there was a trend towards lower symptom burden in the treated group. (more…)
Author Interviews, Diabetes, NEJM / 24.09.2020

Remarks from: Julio Rosenstock, M.D Director, Dallas Diabetes and Endocrine Center Clinical Professor of Medicine University of Texas Southwestern Medical Center Dallas, TX MedicalResearch.com: Why was the study initiated / What is the background of the study? Response: Most people with type 2 diabetes, would prefer simplicity, with fewer injections than currently provided by once-daily basal insulin treatment regimens. Therefore, there is a need to continue to offer innovative treatment options to support people living with type 2 diabetes and hopefully improve their glycemic outcomes. As a once-weekly basal insulin, insulin icodec has the potential to offer a simpler, efficacious and well-tolerated treatment option thereby reducing the potential burden on people living with type 2 diabetes.

Allergies, Author Interviews, CMAJ, Pediatrics / 23.09.2020

MedicalResearch.com Interview with: Melanie Leung, M.D.,C.M. candidate 2021 4th-year medical student at McGill University Division of Allergy and Clinical Immunology Department of Pediatrics, Montreal Children’s Hospital McGill University Health Centre, Montreal, QC, Canada Dr. Moshe Ben-Shoshan, MD, MSc Pediatric allergist and immunologist at the MCH (Montreal Children’s Hospital) and Scientist at the Research Institute of the MUHC (McGill University Health Center)   MedicalResearch.com: What is the background for this study? Response: In Canada, up to 9% of children have at least 1 food allergy. Anaphylaxis is the most severe and potential life-threatening manifestation of food allergy. Peanuts and tree nuts are the main culprits in food-induced anaphylaxis and account for most fatal cases in North America. Public awareness about peanut and nut anaphylaxis can help to prevent and to act promptly, in the case of anaphylactic reaction. However, the best timing for public awareness campaigns remained unknown, as no previous study looked at the potential association between specific times of the year, such as public holidays, and the incidence of peanut and tree nut anaphylaxis. Our aim was to evaluate the risk of peanut and tree nut-induced anaphylaxis on Halloween, Christmas, Easter, Diwali, Chinese New Year, and Eid al-Adha. Data was collected from 1390 pediatric cases of peanut or nut-induced anaphylaxis across Canada (Newfoundland & Labrador, Quebec, Ontario, and British  Columbia), from 2011 to 2020. 62% of children were boys and the median age was 5.4 years. We compared the average daily number of cases during each holiday and compared it to the rest of the year (i.e.: non-holiday period). (more…)
Author Interviews, BMJ, COVID -19 Coronavirus / 23.09.2020

MedicalResearch.com Interview with: Joon Seo Lim, PhD, ELS Clinical Research Center Asan Institute for Life Sciences Asan Medical Center, Songpa-gu Seoul, Republic of Korea MedicalResearch.com: What is the background for this study? Response: The COVID-19 pandemic is continuing to spread at an alarming rate in all parts of the world, and screening individuals based on symptoms (e.g., fever, cough, anosmia) does not seem to be effective in sufficiently curbing the transmission of the disease. This suggests that asymptomatic individuals infected with SARS-CoV-2 may be a driving force of the ongoing pandemic, but empirical evidence on this issue has been lacking because asymptomatic individuals are likely to go unnoticed unless subjected to systematic contact tracing. A large-sized outbreak of COVID-19 from a single religious group in South Korea enabled us to identify and test a large number of asymptomatic individuals with SARS-CoV-2 alongside symptomatic patients from the same cluster.  (more…)

MedicalResearch.com Interview with: David H. Howard, PhD Professor, Health Policy and Management Rollins School of Public Health Emory University, Atlanta, Georgia MedicalResearch.com: What is the background for this study? Response: Application of the False Claims Act (FCA) to medically unnecessary care is controversial, both in the courts and in the Department of Justice. Although there haven’t been many FCA suits against hospitals and physicians for performing unnecessary percutaneous coronary interventions (PCIs), the suits that have occurred have been against some of the highest-volume hospitals and physicians. Some cardiologists have been sentenced to prison. (more…)
Author Interviews, Critical Care - Intensive Care - ICUs, Infections, PLoS / 17.09.2020

MedicalResearch.com Interview with: Prof. Alexandre Mebazaa Head of the Department of Anesthesia and Critical Care Hôpital Lariboisiere and of the Research group MASCOT supported by Inserm and the Université de Paris (Paris, France). Prof. Mebazaa is the principle investigator of the recently published preclinical experiments on Procizumab, a potent, pre-clinical drug candidate targeting DPP3 in patients with acute mycardial depression.  MedicalResearch.com: What is the background for this study? What is the significance of DPP3?  Response: The global burden of sepsis counts for one in three deaths world-wide. Recent findings have shown that circulating Dipeptidyl Pepidase 3 (cDPP3) is elevated in critical patients, including cardiogenic shock and septic patients, with the highest DPP3 blood levels found in non-survivors. Dipeptidyl Peptidase 3 (DPP3) is an intracellular peptidase that is released into the bloodstream upon cell injury and death, where it inactivates many circulating peptides including angiotensin II. This process likely leads to cardiac depression. Procizumab is a humanized monoclonal antibody in preclinical development that targets and modulates DPP3. The aim of the current study was to evaluate the benefits of inhibiting circulating DPP3 by Procizumab in a preclinical model of sepsis-induced myocardial depression. (more…)
AHA Journals, Author Interviews, Blood Pressure - Hypertension, NYU, Race/Ethnic Diversity / 16.09.2020

MedicalResearch.com Interview with: Aisha T. Langford, PhD, MPH Assistant Professor Department of Population Health Co-Director, CTSI Recruitment and Retention Core NYU Grossman School of Medicine NYU Langone Health New York, NY 10016 MedicalResearch.com: What is the background for this study? Response: In 2018, the American Heart Association (AHA) published an updated Scientific Statement on Resistant Hypertension. The term apparent treatment-resistant hypertension (aTRH) is used when pseudoresistance (e.g., white coat effect, medication nonadherence) cannot be excluded. The current study was designed to investigate if Black adults with aTRH, a group disproportionately affected by cardiovascular disease, receive evidence-based approaches to lower blood pressure as recommended in the 2018 AHA Scientific Statement. Specifically, we studied healthy lifestyle factors including not smoking, not consuming alcohol, ≥75 minutes of vigorous-intensity or ≥150 minutes of moderate or vigorous physical activity per week, and body mass index <25 kg/m2; and recommended antihypertensive medication classes among US Black adults.

MedicalResearch.com Interview with: Susan Rowell MD, MBA, MCR Associate Professor, Department of Surgery Division of Trauma, Acute & Critical Care Surgery Duke University School of Medicine Durham, NC 27710 MedicalResearch.com: What is the background for this study? Response: Tranexamic acid (TXA) has been increasingly used in trauma patients since publication of the CRASH-2 trial in 2010 demonstrated a survival benefit for patients at risk for traumatic hemorrhage. Subsequently, it was shown that the earlier TXA was administered, the better the outcome. There had been several small studies suggesting that TXA may also be beneficial in patients with traumatic brain injury (TBI), however, an adequate prospective randomized trial was needed. In this trial we randomized over 1000 patients with moderate and severe TBI as early as possible after injury (by paramedics in the prehospital setting an average of 42 minutes after injury) to either a 1-gram TXA bolus followed by a 1-gram 8-hour TXA infusion (the dose typically used for trauma patients), a 2-gram TXA bolus only (a logistically easier route of administration requiring no maintenance infusion), or placebo only.

MedicalResearch.com Interview with: Chanu Rhee MD MPH Associate Hospital Epidemiologist Attending Physician, Infectious Diseases and Critical Care Medicine Assistant Professor of Medicine Brigham and Women's Hospital MedicalResearch.com: What is the background for this study?   Response: Many patients have been avoiding essential care during the COVID-19 pandemic due to fear of contracting SARS-CoV-2 in healthcare settings. Little is known, however about the adequacy of infection control practices in preventing nosocomial COVID-19 in U.S. acute care hospitals. We therefore conducted this observational study to determine the incidence of nosocomial COVID-19 in patients hospitalized at a large academic medical center in Boston (Brigham and Women’s Hospital) during the first 12 weeks of the surge in Massachusetts.    (more…)
