Author Interviews, Cannabis, CDC, JAMA, Pediatrics / 17.09.2018

MedicalResearch.com Interview with: Katrina Trivers, PhD, MSP Lead author and lead epidemiologist Office on Smoking and Health CDC MedicalResearch.com: What is the background for this study? Response: Although we’ve seen considerable declines in the use of regular cigarettes among U.S. youth over the past several decades, the tobacco product landscape is evolving, and the use of other tobacco products have become increasingly popular. For example, as of 2014, e-cigarettes have become the most commonly used tobacco product among US youth. During 2011-2015, e-cigarette use increased 900% among U.S. high school students before declining in 2016. No change was observed in 2017, with about 2 million youth, including 12% of high school students and 3% of middle school students, reporting they had used e-cigarettes in the past 30 days. This is a public health concern because the use of any form of tobacco product is unsafe among youth, irrespective of whether it’s smoked, smokeless, or electronic. The U.S. Surgeon General has concluded that the aerosol emitted from e-cigarettes is not harmless. It can contain harmful ingredients, including nicotine, carbonyl compounds, and volatile organic compounds known to have adverse health effects. The nicotine in these products is of particular concern given that nicotine exposure during adolescence can cause addiction and can harm the developing adolescent brain. In recent years, many youth have also been using other psychoactive substances in e-cigarettes, including cannabinoids and other illicit drugs. This could have been fueled, in part, by shifts in the social acceptability and access to cannabis as several states have or are considering legalized cannabis sales for adults. A previous CDC study found that in 2015, almost 1 in 3 students reported using e-cigarettes with non-nicotine substances. However, it wasn’t possible to identify what exactly those substances were based on the question. Given the high concurrent use of tobacco and other substances, including cannabis, a more detailed question was added to a future survey to assess the use of cannabis in e-cigarettes among U.S. youth. This study presents the findings from that question. (more…)
Author Interviews, Critical Care - Intensive Care - ICUs, JAMA, Nutrition, Pediatrics / 17.09.2018

MedicalResearch.com Interview with: Sascha Verbruggen, MD, PhD Pediatric intensivist Erasmus MC-Sophia Children's Hospital MedicalResearch.com: What is the background for this study? Response: In critically ill children treated in the pediatric intensive care unit (PICU) are often difficult to feed. The subsequent macronutrient deficit was found to be associated with impaired outcomes in the PICU. Furthermore, being undernourished in the PICU has also been associated with poor outcome of critical illness in children. These associations formed the basis for guidelines recommending initiation of parenteral nutritional support early when enteral feeding is insufficient. However, the multicenter randomised controlled trial (RCT) 'Pediatric Early versus Late Parenteral Nutrition in Critical Illness' (PEPaNIC), including 1440 critically ill children, showed that withholding PN for one week (Late-PN) resulted in fewer new infections and reduced the duration of PICU stay as compared to initiating PN at day 1 (Early-PN). However, withholding PN for one week in critically ill children, who are already undernourished upon admission to the PICU, raised concerns among experts. Therefore we set out to investigate the impact of withholding supplemental PN in a subgroup of critically ill children who were acutely undernourished upon admission to the PICU.  (more…)
Author Interviews, Infections, Pulmonary Disease, Stanford / 15.09.2018

MedicalResearch.com Interview with: Stephen J Ruoss MD Professor, Stanford University, Medicine, Division of Pulmonary and Cfritical Care Medicine Stanford, California MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by an atypical mycobacterial infection?  Response: Our interest in undertaking this study stems from three important clinical observations and issues. First, the use of inhaled steroid medications for a broad variety of respiratory complaints and diseases is increasing, including in clinical circumstances where there isn’t much strong supportive evidence for benefit to patients from using inhaled steroids. The second observation is that steroids can and do alter immune system responses, and can increase the risk for some infections. There are already data from studying patients on inhaled steroids where the incidence of bacterial respiratory infections has increased, supporting the concerns for infection risk from inhaled steroids. And the third issue is that steroids can more specifically alter immune system function that helps combat mycobacterial infections, and this means that the risk for, and incidence of mycobacterial infections could be increased in patients treated with inhaled steroids. The best known mycobacterial infection is of course tuberculosis, but there are other mycobacteria, called nontuberculous mycobacterial (or atypical mycobacterial) that are broadly found in the environment, and some of those nontuberculous mycobacteria (NTM) can cause lung infections. So our hypothesis was that the use of inhaled steroids might be associated with an increased frequency of NTM infections, and we designed the study to explore that hypothesis. (more…)
Author Interviews, Dermatology, Environmental Risks, JAMA, Melanoma / 15.09.2018

MedicalResearch.com Interview with: Lori A. Crane, PhD Department of Community and Behavioral Health Colorado School of Public Health University of Colorado Anschutz Medical Campus, Aurora CO  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Nevi, which are commonly called “moles”, are brown or black spots on the skin that are usually raised.  Moles are the number one risk factor for malignant melanoma, the most dangerous kind of skin cancer.  About 9,000 people die of melanoma each year in the U.S. The more moles a person has, the higher their risk for melanoma.  Sun exposure is a major factor in the development of moles, and in order to prevent melanoma, it is important to better understand how moles are formed on the skin. Most moles are formed during childhood and adolescence.  We studied non-Hispanic and Hispanic white children age 3-16 and found that non-Hispanic children developed many more moles than Hispanic children.  Overall, boys developed more moles than girls, but there were some important differences.  For parts of the skin that are often covered by clothing but sometimes exposed to the sun, such as the chest and back, upper arms and upper legs, girls developed more moles than boys, especially among Hispanic children.  In contrast, for parts of the skin that are usually exposed to the sun, such as the face, boys developed many more moles than girls.  The development of moles leveled off by age 16 for parts of the skin usually exposed to the sun, while for the less often exposed skin, children continued to develop moles to age 16.

Author Interviews, JAMA, Mental Health Research, Omega-3 Fatty Acids / 15.09.2018

MedicalResearch.com Interview with: “omega 3” by Khaldaa Photographer is licensed under CC BY 2.0Yutaka MATSUOKA, MD, PhD Division Chief of Health Care Research, Behavioral Sciences and Survivorship Research Group, Center for Public Health Sciences, National Cancer Center Japan MedicalResearch.com: What is the background for this study? What are the main findings? Response: Anxiety is the most commonly experienced psychiatric symptom. We have now two major treatment options that include cognitive-behavioral therapy (CBT) and pharmacotherapy.  However, CBT is time-consuming, costly, and limited in availability. And there is concern over potential side effects in pharmacotherapy. Evidence-based and safer treatment options are required. Omega-3 fatty acids have potential preventive and therapeutic effects on depression and anxiety. Clinical and preclinical studies support the effectiveness of omega-3 fatty acids as a treatment for anxiety disorders. Despite the largely positive findings of these trials, the clinical application of the findings is unfortunately limited by their small sample size. Improvement in anxiety symptoms were associated with omega-3 fatty acids treatment compared with controls. The anxiolytic effects of omega-3 fatty acids were also stronger in patients with clinical conditions than in subclinical populations.  (more…)
Author Interviews, Breast Cancer, Cancer Research, JAMA, MD Anderson / 15.09.2018

MedicalResearch.com Interview with: Kelly K. Hunt, MD Department of Breast Surgical Oncology The University of Texas MD Anderson Cancer Center Houston MedicalResearch.com: What is the background for this study? What are the main findings? Response: We completed a neoadjuvant trial at MD Anderson Cancer Center and published the results in 2005 demonstrating that trastuzumab delivered in combination with anthracycline and taxane based chemotherapy resulted in pathologic complete response rates of up to 60% in patients with HER-2 positive breast cancer. This was a single institutions study and there was concern about cardiac toxicity when using anthracyclines and trastuzumab concurrently. We therefore worked with the NCI cooperative groups, the American College of surgeons oncology group (ACOSOG), to design the ACOSOG Z1041 trial. This trial compared to different regimens in the neoadjuvant setting, one regimen utilizing concurrent anthracycline and taxanes based chemotherapy with trastuzumab and the other regimen utilizing concurrent taxanes with trastuzumab but the anthracycline was delivered in a sequential fashion. The primary end point of the trial was pathologic complete response rates in the breast. The results from this primary end point were published in the Lancet Oncology in 2013 and showed that the pathologic complete response rates were the same with the 2 different regimens. This was important since patients could be assured of similar efficacy without the potential added toxicity of delivering anthracyclines and trastuzumab together. The current publication is a report of the disease-free and overall survival rates from the Z1041 trial. Several studies have shown an association between pathologic complete response rates and survival. The current study shows that there is no difference in survival rates between the 2 different regimens. So once again there is an association between pathologic complete response and survival and it is not important that the anthracycline and trastuzumab are given concurrently in order to achieve these high pathologic complete response rates and improve survival rates.

Author Interviews, Coffee, Kidney Disease / 14.09.2018

MedicalResearch.com Interview with: Miguel Bigotte Vieira  MD Nephrology and Renal Transplantation Department Centro Hospitalar Lisboa Norte Lisbon, Portugal MedicalResearch.com: What is the background for this study? What are the main findings? Response: An inverse relationship between coffee consumption and mortality has been reported in the general population. However, the association between caffeine consumption and mortality in patients with chronic kidney disease (CKD) remains unclear. We examined the association between varying levels of caffeine consumption and mortality among 4863 patients with CKD in a prospective nationwide cohort, using the continuous National Health and Nutrition Examination Survey (NHANES) 1999-2010. Our study showed a protective effect of caffeine consumption among patients with chronic kidney disease. The reduction in mortality was present even after considering other important factors such as age, gender, race, smoking, other diseases, and diet.  (more…)
Author Interviews, Cancer Research, Gastrointestinal Disease, Infections / 14.09.2018

MedicalResearch.com Interview with: Nina R. Salama. PhD Member Human Biology Division Member Public Health Sciences Division Affiliate Member Basic Sciences Division Dr. Penny E. Petersen Memorial Chair for Lymphoma Research Director of Molecular and Cellular Biology (MCB) Graduate Program Fred Hutchinson Cancer Research Center  MedicalResearch.com: What is the background for this study? What are the main findings? Response: We wanted to better understand why certain patients infected with H. pylori developed stomach cancer and how we could better identify them. H. pylori is one of the strongest risk factors for stomach cancer, but how much it predisposes individuals to gastric cancer varies around the world. Working closely with colleagues from Zhengzhou University, we ran tests on 49 samples from China and found that 91 percent of patients infected with the EPIYA D gene variant of H. pylori also had stomach cancer.

Author Interviews / 14.09.2018

MedicalResearch.com Interview with: Dr. Tyler J. VanderWeele PhD Department of Epidemiology, Harvard T. H. Chan School of Public Health, Boston, MA MedicalResearch.com: What is the background for this study? What are the main findings? Response: There have been a number of prior studies on religious practices of adolescents, but this study is a relatively big step forward because it is considerably more rigorous than the vast majority of prior studies. The study uses a large sample of over 5,000 adolescents, it follows them up for more than eight years, it controls for many other variables to try to isolate the effect of religious upbringing, and it looks at many outcomes. In our analysis, we found that children who were raised in a religious or spiritual environment were subsequently better protected from the “big three” dangers of adolescence – depression, substance abuse and risky behaviors. For example, those who attended religious services regularly were subsequently:
  • 12% less likely to have high depressive symptoms
  • 33% less likely to use illicit drugs
Those who prayed or meditated frequently were:
  • 30% less likely to start having sex at a young age
  • 40% less likely to subsequently have a sexually transmitted infection.
Moreover, a religious upbringing also contributed towards to a number of positive outcomes as well such greater happiness, more volunteering in the community, a greater sense of mission and purpose, and higher levels of forgiveness. For example,those who attended religious services were subsequently:
  • 18% more likely to report high levels of happiness
  • 87% more likely to have high levels of forgivenessThose who prayed or meditated frequently were subsequently:
  • 38% more likely to volunteer in their community
  • 47% more likely to have a high sense of mission and purpose
These are relatively large effects across a variety of health and well-being outcomes.  (more…)
Author Interviews, Education, Exercise - Fitness / 14.09.2018

“Girl Playing Soccer” by Bold Content is licensed under CC BY 2.0MedicalResearch.com Interview with: Craig Pulling. MSc, PGCE, BA (Hons), FHEA Head of Physical Education University of Chichester MedicalResearch.com: What is the background for this study? Response: Successful perceptual-cognitive skill in team-sports such as football requires players to pick up task-relevant information during the control of action in complex and dynamic situations. It has been proposed that players could perform visual exploratory activity (VEA) to be able to recognise important cues in the playing environment. VEA is defined as: “A body and/or head movement in which the player’s face is actively and temporarily directed away from the ball, seemingly with the intention of looking for teammates, opponents or other environmental objects or events, relevant to perform a subsequent action with the ball” (Jordet, 2005, p.143). Research has suggested that VEA is an important facet of skilled performance in youth and adult football. However, it is currently unknown whether such evidence is commensurate with the views of coaches and whether coaching practices are utilised to develop VEA in training. In order to further current understanding on VEA and coaching practices, the present study developed an online survey to examine: (i) when VEA should be introduced in coaching; (ii) how VEA is delivered by coaches and (iii) how coaches evaluate VEA. Further, this study aimed to explore whether distinct groups of football coaches existed who differed in their approach to the delivery of VEA training and, if so, whether there were differences in the demographics of the coaches across these differentiated groups.

Author Interviews, JAMA, Ophthalmology, Toxin Research / 14.09.2018

MedicalResearch.com Interview with: “Vision” by Victoria Ford is licensed under CC BY 2.0Adam J. Paulsen MS Associate Researcher EpiSense Research Program Department of Ophthalmology&  Visual Sciences University of Wisconsin - Madison MedicalResearch.com: What is the background for this study? Response: Contrast Sensitivity is a measure of visual function that indicates how well a person is able to distinguish an object against its background.  Tests of CS determine how faint a visual signal can be identified.  CS can be diminished even in those with appropriately corrected visual acuity, has been shown to have effects on daily activities (including near vision tasks), risk of falls, and driving ability.  The causes of and risks for CS impairment are understudied.  Cadmium (Cd) and Lead (Pb) are known neurotoxins that have been shown to accumulate in the retina.  Both Cd and Pb have common sources of exposure in the general population.  Our studied aimed to investigate risk factors for incident CS impairment, including Cd and Pb exposure.

Author Interviews, JAMA, Opiods, Social Issues / 14.09.2018

MedicalResearch.com Interview with: Hanna Grol-Prokopczyk PhD Assistant Professor, Department of Sociology University at Buffalo, SUNY MedicalResearch.com: What is the background for this study? Response: Studies examining predictors of prescription opioid use often have limited information about users’ socioeconomic status, their level of pain, and their opinions of opioids.  Using unique data from the Health and Retirement Study’s 2005-2006 Prescription Drug Study—which includes information about older adults’ education, income, wealth, insurance type, pain level, and opinions of prescription drugs used—I was able to explore how socioeconomic factors shaped prescription opioid use in the 2000s, when U.S. opioid use was at its peak.  I was also able to present a snapshot of how users of prescription opioids felt about these drugs before the declaration of an opioid epidemic.

Author Interviews, JAMA, Outcomes & Safety, Surgical Research / 14.09.2018

MedicalResearch.com Interview with: Tanya L. Zakrison, MHSc MD FRCSC FACS MPH Associate Professor of Surgery University of Miami Miller School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Over 2 million people in the United States are incarcerated, the highest rate in the entire world.  To date no national statistics on surgical outcomes have been reported in this vulnerable patient population.  We examined 301 medical examiner’s reports from prisoner deaths in Miami-Dade County.  Excluding those with confounding medical conditions such as cirrhosis and cancer, we still found that one in five deaths were being attributed to trauma and reversible surgical diseases.    (more…)
Author Interviews, Cost of Health Care, Global Health, Infections, Vaccine Studies / 13.09.2018

MedicalResearch.com Interview with: Veronica Toffolutti PhD Research Fellow in Health Economics Bocconi University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Austerity has been linked to several health damaging effects such as suicides, increase in unmet needs, disease outbreaks that affect vulnerable peoples such as malaria in Greece, HIV in Greece and Romania during the current economic crises or in the earlier economic crisis cuts in public health expenditure have been linked with diphtheria and TB. Europe is experiencing declining vaccination rates and resurgences in measles incidence rates. Italy appears to be particularly affected reporting the second largest number, second to Romania, of infection in Europe in 2017. Starting from the point that the primary reason for the outbreak in the decline in the measles vaccination we test the hypothesis that large budget reductions in public health spending were also a contributing factor. Using data on 20 Italian regions for the period 2000-2014 we found that each 1% reduction in the real per capita public health expenditure was associated with a decrease of 0.5 percentage points (95% CI: 0.36-0.65 percentage points) in MMR coverage, after adjusting for time and regional-specific time-trends.  (more…)
Addiction, Author Interviews, JAMA / 13.09.2018

MedicalResearch.com Interview with: Ti-Fei Yuan, PhD School of Social and Behavioral Sciences, Nanjing University, Nanjing, China Shanghai Key Laboratory of Psychotic Disorders, Shanghai Mental Health Center, Shanghai Jiaotong University School of Medicine, Shanghai, China Co-innovation Center of Neuroregeneration, Nantong University, Nantong, Jiangsu, China Guangdong-Hongkong-Macau Institute of CNS Regeneration, Ministry of Education CNS Regeneration Collaborative Joint Laboratory, Jinan University, Guangzhou, China School of Psychology, Nanjing Normal University, Nanjing, China MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Addiction is causing serious challenge to public health. Few drugs can treat or even alleviate addiction. In recent years, non-invasive brain stimulation has been used to modulate craving responses in different types of drug addicts (heroin, methamphetamine, cocaine), and to prevent smoking or alcohol abuse. However it is unknown if brain stimulation can also help addicts get rid of the aversive symptoms in the early withdrawal period. The present study is to our knowledge, the first trial to alleviate drug withdrawal symptoms and associated insomnia with non-invasive transcranial magentic stimulation.  (more…)
Author Interviews, Cancer Research, Immunotherapy, JAMA, Vanderbilt / 13.09.2018

MedicalResearch.com Interview with: Douglas B. Johnson, M.D. Assistant Professor of Medicine Clinical Director, Melanoma Research Program Melanoma, clinical and translational studies Vanderbilt University Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: Immune checkpoint inhibitors produce long-lasting responses in patients with many different types of cancer. However, they may cause serious autoimmune-like side effects that may affect any organ. We used several large databases to determine how often these side effects were fatal, when they occurred, and which types of side effects were responsible. We found that overall, fatal side effects were uncommon, ranging from 0.3 – 1.3%. However, they tended to occur early on treatment (on average within the first 6 weeks), and affected a variety of organs, including the heart, lungs, colon, liver, and brain. There was a dramatic increase in reporting of fatal toxicities since 2017, likely reflecting the increased use of immune checkpoint inhibitors.  (more…)

MedicalResearch.com Interview with: Andrea L. Roberts, MPH, PhD Research Associate, Department of Social and Behavioral Sciences Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? Response: There is some evidence that depression may increase risk of autoimmune diseases. For example, among people with autoimmune diseases, more people have depression than in the general population. Also, people who have autoimmune diseases who also have depression have more severe disease symptoms. (more…)
Author Interviews, Cannabis, Pain Research / 13.09.2018

MedicalResearch.com Interview with: Jacob M. Vigil, PhD Department of Psychology University of New Mexico MedicalResearch.com: What is the background for this study?   Response: For the past several years we have been using observational research designs as a means to overcome some of the logistical and legal barriers for conducting patient outcomes medical cannabis research. In partnership with the software developers of the Releaf App which currently is the largest repository of user-entered information on the consumption and effects of cannabis use in the United States, we have been able to measure how patients choose to consume cannabis and the effects of those choices in real-time.  Since its release in 2016, the commercially developed Releaf App has been the only publicly available, incentive-free patient educational software program designed for recording how individual cannabis usage sessions correspond to immediate changes in symptom intensity levels and experienced side effects.

Author Interviews, Pain Research, Surgical Research / 12.09.2018

MedicalResearch.com Interview with: Wayne B. Jonas, MD Clinical Professor of Family Medicine Uniformed Services University and at Georgetown University School of Medicine MedicalResearch.com: What is the background for this study? Response: The search for non-drug approaches to chronic pain is a major recommendation in many recent guidelines for both pain management and reduction in the use of opioids. Surgical and invasive procedures are non-drug approaches often used for pain conditions like back pain and arthritis, so good evidence is needed to determine the safety and efficacy of these procedures. Properly done randomized, placebo controlled trials are the best way (the gold standard) to get that evidence, so we did a thorough evaluation of such research, using standard systematic review and meta-analysis methods.

Author Interviews, Critical Care - Intensive Care - ICUs, Infections, JAMA / 12.09.2018

MedicalResearch.com Interview with: Patrick Harris FRACP Staff Specialist Microbiology | Pathology Queensland | Health Support Queensland Postdoctoral Research Fellow University of Queensland, UQ Centre for Clinical Research (Paterson Group MedicalResearch.com: What is the background for this study? Response: Increasingly, common bacterial pathogens such as E. coli or Klebsiella have acquired genes known as extended-spectrum beta-lactamases (ESBLs), which mediate resistance to many of our most important antibiotics. Despite their clinical importance, we have limited information derived from randomised clinical trials on the best antibiotic treatments for life-threatening infections caused by these ESBL-producers. We aimed to compare two readily available antibiotics, meropenem (a carbapenem drug, as the “standard of care”) and piperacillin-tazobactam (which may be an alternative to meropenem). Many ESBL-producing bacteria test susceptible to piperacillin-tazobactam in the laboratory, yet clinical efficacy has been uncertain.  Some observational studies have suggested that piperacillin-tazobactam may be effective against ESBL-producers, but the data have been contradictory.  The theory has been that piperacillin-tazobactam may be less likely to select for resistance to carbapenems - which, when it occurs, can result in infection with bacteria that are almost untreatable.

Accidents & Violence, Author Interviews, Critical Care - Intensive Care - ICUs, JAMA, Surgical Research / 12.09.2018

MedicalResearch.com Interview with: Adil Haider, MD, MPH, FACS Kessler Director for the Center for Surgery and Public Health Brigham and Women’s Hospital, Harvard Medical School, and Harvard T.H. Chan School of Public Health Deputy Editor of JAMA Surgery MedicalResearch.com: What is the background for this study? Response: Firearm-related mortality is a public health issue. However, in the US, due in part to lack of funding, there is not enough research to inform the debate about firearms. The question our group sought to answer was to understand if the presence of a semi-automatic weapon increased the number of victims killed or hurt during an active shooter incident. We chose to focus on these incidents given the availability of an FBI database detailing these active shooter incidents based on a strict definition and the similarities between such incidents that make a comparison valid.

Author Interviews, Diabetes, JAMA, OBGYNE / 12.09.2018

MedicalResearch.com Interview with: Boyd E Metzger, MD Professor Emeritus of Medicine (Endocrinology) Feinberg School of Medicine Northwestern University MedicalResearch.com: What is the background for this study? Response: The Hyperglycemia and Adverse Pregnancy Outcome (HAPO) Study showed that higher levels of a mother’s blood sugar during pregnancy are associated with higher risks of increased birthweight, fatter babies, delivery by Cesarean Section, low blood sugar in newborn babies and high levels of insulin in the cord blood at birth. It is not clear whether levels of a mother’s blood sugar during pregnancy are associated with risk obesity later in life as is known to occur in offspring or pre-existing maternal diabetes mellitus. With funding from the National Institutes of Health, the HAPO Follow Up Study addressed this in a subset of nearly 5,000 mothers and their children from the original HAPO Study 10-14 years later (average 11.4 years).

Alzheimer's - Dementia, Author Interviews / 12.09.2018

MedicalResearch.com Interview with: Elena LeychenkoElena Leychenko is a senior research associate at PIBOC (G.B. Elyakov Pacific Institute of Bioorganic Chemistry which is the Far Eastern Branch of the Russian Academy of Sciences), assistant professor, and lecturer at the chair of bioorganic chemistry and biotechnology of the School of Natural Sciences Far Eastern Federal University  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Sea anemones are the main object for study in the laboratory for peptide chemistry of PIBOC. These marine dwellers are very interesting for scientists because of a wide range of biologically active compounds, which are the main components of their venom. The development of modern research methods allows us to receive both major and minor components of that poison, and to study their medical properties. Interestingly, inhibitors of Kunitz-type proteinases, which are also content in sea anemones, can be used as anti-inflammatory compounds. In particular, in complex therapy, it could be applied in the treatment of Alzheimer's disease.  (more…)
Author Interviews, JAMA, Ophthalmology, Primary Care, University of Michigan / 11.09.2018

MedicalResearch.com Interview with: Joshua Ehrlich, MD, MPH Assistant Professor of Ophthalmology and Visual Sciences University of Michigan  MedicalResearch.com: --Describe the “important role” that primary care providers play in promoting eye health? Response: Primary care is the entryway into the health system for many individuals. The poll suggests that when primary care providers discuss vision with their patients, they are more likely to get eye exams. It also suggests that primary care providers are having these conversations most often with those who have certain risk factors for eye disease, such as diabetes or a family history of vision problems, as well as those with fewer economic resources. Promoting these kinds of conversations could bolster this trend, increasing the number of diabetics and other high risk individuals who get appropriate eye care. (more…)
Author Interviews, Biomarkers, Cancer Research, Immunotherapy, Melanoma, Nature / 11.09.2018

MedicalResearch.com Interview with: Dr. Noam Auslander PhD National Cancer institute and the Center for Bioinformatics and Computational Biology University of Maryland, College Park MedicalResearch.com: What is the background for this study? Response: Immunotherapy – specifically immune checkpoint blockage (ICB) therapy – has been shown to be very effective in treating melanoma. However, only some patients with advanced tumors currently benefit from ICB therapies, while others are completely resistant and hence can be spared from the associated side effects and costs. Hence, predicting which patients are most likely to respond is an important challenge that can have great clinical benefits.   (more…)
Author Interviews, Leukemia / 11.09.2018

MedicalResearch.com Interview with: Hans van Eenennaam, Ph.D. Executive vice president antibody research and site head Aduro Biotech Europe MedicalResearch.com: What is the background for this study? Response: A PRoliferation Inducing Ligand (APRIL) is a member of the tumor necrosis factor superfamily and has been shown to stimulate the proliferation and survival of healthy B-lymphocytes. Malignant B-lymphocytes, such as multiple myeloma, use APRIL primarily in the bone marrow to support its proliferation and survival. Studies have shown that APRIL is overproduced in patients with multiple myeloma and mediates primarily via binding to B-cell maturation antigen (BCMA) to stimulate a wide variety of responses that promote multiple myeloma growth and survival, as well as suppressing the immune system so that the tumor cells are protected and sustained in the bone marrow and can escape current available treatments.

Aging, Author Interviews, Exercise - Fitness, Geriatrics, JAMA / 10.09.2018

MedicalResearch.com Interview with: Peter A. Harmer, PhD., MPH., ATC., FACSM Professor - Department of Exercise & Health Science Willamette University MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Falls in older adults have long been a significant healthcare problem associated with loss of independence, premature morbidity and mortality, and considerable financial strain on individuals and healthcare systems. With the demographic impact of the Baby Boom generation aging into retirement, this issue is becoming even more critical. Among potential prevention strategies, exercise has been proposed to be beneficial. However, establishing what types of exercise are suitable to the task has been problematic. More importantly, identifying differences in the effectiveness of various exercise approaches has been lacking. (more…)
Addiction, Author Interviews, JAMA, Mental Health Research, University of Michigan / 10.09.2018

MedicalResearch.com Interview with: Lauren B. Gerlach, D.O. Clinical Lecturer Department of Psychiatry University of Michigan MedicalResearch.com: What is the background for this study?  Response: In this study we used data from the Supporting Seniors Receiving Treatment and Intervention or SUSTAIN program. The program provides a supplement to a Pennsylvania medication coverage program for low-income older adults. It provides behavioral health and case management services by phone across the state. This included detailed interviews to screen for mental health issues including anxiety, depression, sleep issues, and pain, as well as analysis of prescription records and other clinical data. Among older adults prescribed a new benzodiazepine prescription by a non-psychiatric provider, we determined how many then went on to long-term use of the medication and what patient and clinical characteristics predicted long-term use over the following year.

MedicalResearch.com Interview with: Scott E. Hadland, MD, MPH, MS Assistant Professor of Pediatrics Boston Medical Center / Boston University School of Medicine MedicalResearch.com: What is the background for this study? Response: Amidst a worsening overdose epidemic in the United States, adolescents and young adults have not been spared. Although evidence-based medications like buprenorphine, naltrexone, and methadone are recommended for adolescents and young adults, the extent to which youth receive these medications — and whether these medications help retain youth in addiction treatment — isn’t yet known.

Author Interviews, Cancer Research, Dermatology, Heart Disease, JAMA, Vaccine Studies / 10.09.2018

MedicalResearch.com Interview with: Dr. Jeffrey Rapaport MD, PA Emeritus head of Dermatology Teaneck's Holy Name Hospital. Dr. Rapaport discusess a case recently reported in JAMA: In 2016: A 97-year-old female patient was suffering from multiple squamous cell carcinomas varying from small to incredibly large in size on both of her legs. She was injected with the HPV vaccine commonly known as Gardasil, which is also used to treat warts and oral papilloma. She was first injected in her arm, and then after a period of six weeks, the vaccine was directly injected into her tumors. It was observed that this treatment eventually killed off almost all the tumors on her legs. According to recent press coverage, she is now looking forward to celebrating her 100th birthday in fall 2018. MedicalResearch.com: What is the background for this study?Is HPV thought be a trigger for some cutaneous squamous cell carcinomas? Response: The link between skin cancers and HPV vaccinations has normally been investigated in patients who have received organ transplants. Due to the immune-suppressant drugs these patients must take, it is incredibly common to find cases of skin cancer in patients who have undergone transplants. The relaxed immune system, which would normally eliminate cancers caused by the HPV virus, would open the floodgates for multiple skin tumors to emerge. In this case of the 97 year old, I would assume her immune system was healthy. There is, however, growing evidence that receiving multiple vaccines for the HPV virus is necessary even in patients with healthy immune systems. So, regardless of immune health, I believe we need to expand the frequency of the HPV vaccine, even beyond the current three-tiered system for women below 26 and men below 21. (more…)
