MedicalResearch.com Interview with: [caption id="attachment_55596" align="alignleft" width="133"]Donna R. Cryer, JD Donna R. Cryer, JD[/caption] Donna R. Cryer, JD President & CEO of the Global Liver Institute  MedicalResearch.com: What is the background for this announcement? What is the mission of the GLI? Response: Global Liver Institute 's (GLI) mission is to improve the impact of the liver community by promoting innovation, collaboration, and scaling optimal approaches to eradicating liver diseases. Our vision is for liver health to take its proper place on the global public health agenda consistent with its prevalence and impact. One of the ways we seek to fulfill that mission is through a #OctoberIs4Livers worldwide awareness campaign for the fight against liver cancer, reinforcing October as liver disease and liver cancer awareness month. Not only are we seeing a continuous rise of prevalence of liver cancers, but survival rates for liver cancers are also some of the lowest of any cancer. Even more concerning is that the startling truth about the rise of liver cancer rates began before the COVID-19 pandemic. With the added burden of COVID-19, patients directly at risk from the virus may be diagnosed at a later stage due to delayed screening, and are getting sicker due to limitations on access to care during this pandemic. GLI is appealing to the US Congress to act now to secure the health and well-being of people living with liver disease and liver cancers during COVID-19. Funding is crucial to ensure federal agencies can restart and continue medical research, implement targeted prevention, and support awareness efforts for those impacted by liver disease as they are at increased risk for severe illness from COVID-19.

How common is Stage I-IIA non-squamous NSCLC?  DetermaRxTM is a treatment stratification test to identify patients with Stage I-IIA non-squamous NSCLC who may benefit from adjuvant chemotherapy.
  • Stage I-IIA non-squamous NSCLC represents ~20% of the lung cancer population and 40,000 patients annually in the U.S.1
  • Patients with this diagnosis usually undergo surgical resection and are presumed “cured”. While these patients are presumed “cured”, the recurrence rate in early-stage NSCLC of 30-50%. Usually, these recurrences happen within the first two years after surgery and are likely due to the presence of occult distant metastasis at the time of surgery.2
  • Until now, there has not been a validated means of identifying which early-stage patients are at a higher risk of disease recurrence and require adjuvant chemotherapy, versus those patients that are likely cured by surgery alone.

Senior, MD, FACS, FARS Professor of Otolaryngology/Neurosurgery Vice Chairman for Clinical Affairs Nathaniel and Sheila Harris Distinguished Professor Chief, Division of Rhinology, Allergy, and Endoscopic Skull Base Surgery Department of Otolaryngology-Head and Neck Surgery University of North Carolina at Chapel Hill Chapel Hill, NC MedicalResearch.com: What is the background for this study? How common is the problem of chronic rhinosinusitis with nasal polyps? Response: Chronic rhinosinusitis (CRS) is a very common illness in the United States and around the world, estimated to impact 2-14% of the US population. Chronic rhinosinusitis with polyps is a particularly challenging form of the disease marked by significant impact on quality of life, and being challenging to treat with significant recurrences of symptoms despite standard medical and surgical treatment. Inhaled intranasal steroids are standard therapy for patients with CRS including those with nasal polyps. However, many patients continue to have significant nasal symptoms despite treatment with these medications. This study was designed to answer the question of whether patients who had been receiving treatment with inhaled intranasal steroids and failed were improved by using EDS-FLU. Results were obtained by pooling data from two previous studies of the use of EDS-FLU in patients with CRS, called Navigate 1 and 2.

Response: During the COVID-19 pandemic, food insecurity is expected to rise given economic uncertainty and job losses. Vulnerable and marginalized populations are disproportionately affected by both COVID-19 and food insecurity. MedicalResearch.com: What are the main findings? Response: In this perspective, we argue that food insecurity and COVID-19 can exacerbate one another via bidirectional links. Experiencing food insecurity can lead to nutritional deficiencies and weakened host defenses, increasing susceptibility to COVID-19 infection. Food insecurity is also associated with chronic medical conditions which may lead to a higher risk of severe COVID-19 illness. Conversely, people with COVID-19 may not be able to work, generate income, or procure food while quarantined, which may worsen food insecurity.

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%+).

For more information on Troy Campbell, please visit: www.troy-campbell.com MedicalResearch.com: What is the background for this study? What are the main findings?  Response: In the United States, the average American sleeps less than the minimum seven hours of sleep per night recommended by the Center for Disease Control, and nearly half of Americans report negative consequences from insufficient sleep. This problem appears to be especially prevalent in men, who report getting significantly less sleep, on average, than women. A cultural complication is the notion that getting less than the recommended amount of sleep signals something positive about an individual. For example, US President Donald Trump has boasted about getting less than four hours of sleep per night and regularly derogates his political opponent Joe Biden as “Sleepy Joe.” "The Sleep-Deprived Masculinity Stereotype," a new paper in the Journal of the Association for Consumer Research, examines a possible stereotype connecting sleep and masculinity along with its underlying mechanisms and its social implications. Authors Nathan B. Warren and Troy H. Campbell conducted 12 experiments involving 2,564 American participants to demonstrate that a sleep-deprived masculinity stereotype exists.  In one experiment, participants were asked to imagine seeing a man shopping for a bed. Then, a salesperson asked the man, “How much do you normally sleep?” The results found that the mean masculinity rating for participants in the lots of sleep condition was significantly lower than the mean masculinity rating for participants in the little sleep condition. In another experiment, participants were asked to ascribe different attributes to a male character, assigned to either a “very masculine and manly” man or a “not very masculine and not very manly” man. Participants in the masculine condition described their character sleeping 33 minutes less sleep per night than the characters described in the not masculine condition. A final experiment showed that participants who imagined stating they sleep more than average felt significantly less masculine than participants who imagined stating they sleep less than average. Collectively, the experiments found that men who sleep less are seen as more masculine and more positively judged by society. The same patterns were not consistently observed for perceptions of women.

MedicalResearch.com Interview with: [caption id="attachment_55564" align="alignleft" width="180"]Evan J. Anderson, MD Associate Professor of Medicine and Pediatrics Emory University School of Medicine Dr. Anderson[/caption] 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.

MedicalResearch.com Interview with: Heather Breeze Clayton, PhD, MPH Senior Scientist, National Center for Injury Prevention and Control CDC MedicalResearch.com: What is the background for this study? Response: Thirty-three states and the District of Columbia now have policies in place legalizing marijuana for medical or adult use. While the health effects of marijuana use continue to be studied, substantial evidence suggests that a number of health risks – including cognitive and mental health outcomes- are made worse by earlier initiation of marijuana, and heavier use patterns. Scientific knowledge about the association between marijuana use and other health and risk-taking behavior in youth is still evolving. Accordingly, we sought to use nationally representative data from the Youth Risk Behavior Survey to assess what the relationship is between different patterns of marijuana use in youth (more established use vs. non-established use patterns) and a number of risk-taking and violence related behaviors.

What are the main findings?
  • SUNRISE 2 was one of two pivotal Phase 3 studies evaluated in the U.S. Food and Drug Administration’s approval of DAYVIGO (lemborexant) CIV in December 2019.
  • SUNRISE 2 was a pivotal six-month placebo-controlled treatment trial with a 6-month active treatment period including adult patients age 18 or older who met DSM-5 criteria for insomnia disorder.
  • Patients were randomized to placebo (n=325), DAYVIGO 5 mg (n=323), or DAYVIGO 10 mg (n=323) once nightly for the first six months of the study (Treatment Period 1).
  • The primary efficacy endpoint was the mean change from baseline to end of treatment at six months for subjective sleep onset latency (sSOL; the estimated minutes from the time that the patient attempted to sleep until sleep onset).
  • Secondary efficacy endpoints were mean change from baseline to end of treatment at six months subjective sleep efficiency (sSE; the proportion of time spent asleep per time in bed) and subjective wake after sleep onset (sWASO; the minutes of wake from the onset of sleep until wake time). These endpoints were measured by sleep diary.
  • At Virtual SLEEP 2020, a post-hoc analysis of SUNRISE 2 was shared in an oral presentation, which looked specifically at the long-term efficacy and safety of lemborexant in elderly adults with insomnia disorder.
  • Insomnia disorder, a chronic condition with long-term consequences for health and well-being, is prevalent in older adults.
  • This analysis of the SUNRISE 2 data reflects new learnings on the sustained impact of DAYVIGO on sleep onset and sleep maintenance in an older patient population.

Driskell Ph.D. Assistant Professor School of Molecular Biosciences Center for Reproductive Biology Washington State University Pullman, WA. 99164  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Scars a serious health concern when they cover large areas of the body. Understanding how to functionally regenerate skin can improve the quality of life for individuals with large scars. Importantly, our study is proof of concept, in that we identified a genetic factor that allows adult skin to repair itself like the skin of a newborn babe. The discovery has implications for better skin wound treatment as well as preventing some of the aging process in skin.

MedicalResearch.com Interview with: [caption id="attachment_55549" align="alignleft" width="150"]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 Dr. Wenquan Zou[/caption] 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.

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.

Response: This large collaborative project involving participants and researchers from around the world which has been underway for about 10 years. The aim was to try and identify genetic variants that influence handedness with the goal of increasing our knowledge about the way lateralization develops in behaviour and in the brain. In this project we were able to bring together results from cohort studies conducted by academic collaborators, the UK Biobank and 23andMe yielding a total sample size of over 1.7 million participants. Working with Professor David Evans the co-senior author of the paper (University of Queensland) and Dr Gabriel Cuellar-Partida the first author of the paper (formally UQ now at 23andMe) and the other researchers who worked on the project we meta-analysed the genome-wide association analysis results from the cohorts and were able to identify 41 genetic variants that influence left-handedness and 7 that influence ambidextrousness.

MedicalResearch.com Interview with: Dr. Liron Rozenkrantz Postdoctoral Fellow Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology Program in Placebo Studies, Harvard Medical School Former PhD student at Human Olfaction Research group, Department of Neurobiology Weizmann Institute of Science Reut Weissgross Research student Human Olfaction Research group, Department of Neurobiology Weizmann Institute of Science MedicalResearch.com: What is the background for this study? Response: A pregnancy loss is not such a rare event as you would think: it is estimated that about 50% of all conceptions (or 15% of the documented pregnancies) end in spontaneous miscarriage. About 1-2% of all couples trying to conceive will experience recurrent pregnancy loss (RPL), meaning 2-3 consecutive miscarriages, and despite going through numerous clinical investigations (hormonal tests, genetics and so) - about half of these cases will remain unexplained. This devastating phenomenon leaves couples with no explanation as to why they cannot bear a child. While most research in this field is focused on the reproductive organs (mainly the uterus), hormones and genes, we set out to look for new possible routes. The literature regarding the tight connection between olfaction and reproduction, mainly by social body-odors (or pheromones), is heavily documented, especially in rodents. Body-odors emitted from males affect pubertal development of juvenile female rodents and estrus cycle, and females body odors affect other females’ fertility state. The most robust phenomenon in this relation is the Bruce effect, in which pregnant female mice who are exposed to body-odors from a non-stud male - will experience impanation failure in 80% of exposures! Since there is growing evidence for the involvement of the olfactory system in human reproduction, we asked whether the olfactory system is also involved in human reproductive disorders such as unexplained recurrent pregnancy loss (uRPL). To answer this question, we recruited 40 women experiencing uRPL and 57 matched controls (who never experienced a miscarriage, and are at similar age to the uRPL women), and compared their olfactory profile, mainly in response to men’s body-odors.

Botox treatment was created to make undesirable physical lines less visible. It is an efficient way to bring the natural facial appeal back to its normal condition. By getting quick and painless Botox injections, you can maintain the appearance you want most. There are a lot of myths surrounding the treatment, but the popularity of Botox is a very real thing.

botox-facial-fillers-wrinkles-skin care The Stars Know

When you hear about Botox, it is usually attached to a celebrity story. This type of treatment is very popular in Hollywood circles, and for good reason. It is an effective way to keep a specific look without major cosmetic surgery. When time is of the essence, Botox has no equal. You can set up an appointment, get the injections, and see results as early as three days. That is a single weekend required to get good looking results without breaking the bank. Hollywood is a business that relies on looks, so the popularity of Botox is no surprise. Its effectiveness on the most beautiful people in the world is the main reason why it’s still trending.

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.
Author Interviews, COVID -19 Coronavirus / 29.09.2020

MedicalResearch.com Interview with: Dr Stephen Poole BRC Clinical Research Fellow from the Southampton Southampton, UK MedicalResearch.com: What is the background for this study? Response: Our understanding of how the emergence of COVID 19 (SARS-CoV-2) has effected existing seasonal respiratory viruses, like influenza or common cold viruses, is limited. Many labs stopped or reduced their testing for these other respiratory viruses during the first epidemic peak as healthcare providers were trying to save resources for COVID-19 testing. We know that the viruses in circulation prior to COVID caused a lot of exacerbations of asthma and chronic obstructive pulmonary disease (COPD) but it is unclear whether this is the case with SARS-CoV-2. The aims of our study were to measure the impact of the emergence of SARS-CoV-2 on other respiratory viruses and to compare the patterns of illness. Our group in Southampton, UK led by Dr Tristan Clark were uniquely positioned to be able to do this. We have run 3 large trials in the last 5 winters which have tested for a wide range of respiratory viruses all in the same group of patients: adults arriving in hospital with a recent onset respiratory illness. We use this to compare the proportion of tests which were positive in the height of the COVID pandemic (March-May) with the same time period in previous years.

MedicalResearch.com Interview with: Gizem Kilic MSc, PhD Candidate} Radboud University Medical Center Department of Internal Medicine Laboratory of Experimental Internal Medicine Nijmegen MedicalResearch.com: What is the background for this study? Response: Having emerged in Wuhan, China in December 2019, novel coronavirus infection 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) has become a major health crisis affecting worldwide. Although the disease symptoms are mild in most of the cases, it is known that advanced age and co-morbidities such as diabetes and cardiovascular diseases increase the risk of disease severity. Moreover, epidemiological data from different countries indicated that the mortality rate is higher in males compared to females. There are reports suggesting that some viral and bacterial infection are sex-biased; however, why males are more susceptible to develop severe COVID-19 infection has not been fully understood yet.

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.

MedicalResearch.com Interview with: [caption id="attachment_55479" align="alignleft" width="150"]Shuchi Anand M.D. M.S. Director of the Center for Tubulointerstitial Kidney Disease Stanford University Dr. Anand[/caption] 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.

Our study investigated all patients hospitalized for treatment of COVID at a major US academic medical center during the study period. We studied patients who were hospitalized with COVID-19, and compared those who had been taking statins for at least 30 days prior to admission, with those not on statins.

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.

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.

MedicalResearch.com Interview with: [caption id="attachment_55471" align="alignleft" width="150"]Dr-Maria Gabriela Figueiro Longo Dr. Figueiro LongoTBI[/caption] 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.

Remarks from: [caption id="attachment_55474" align="alignleft" width="140"]Julio Rosenstock, M.D Director, Dallas Diabetes and Endocrine Center Clinical Professor of Medicine University of Texas Southwestern Medical Center Dallas, TX Dr. Rosenstock[/caption] 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.
