MedicalResearch.com Interview with: Murad Alam, MD Vice-Chair and Professor of Dermatology Chief of Cutaneous and Aesthetic Surgery Northwestern University Feinberg School of MedicineMurad Alam, MD Vice-Chair and Professor of Dermatology Chief of Cutaneous and Aesthetic Surgery Northwestern University Feinberg School of Medicine MedicalResearch.com: What is the background for this study? Response: For the purposes of our study, non-invasive procedures included laser and light treatments (for brown spots, blood vessels, wrinkle reduction, scar treatment, hair removal ie laser hair removal or Hair Removal Service - sponsored), chemical peels, and non-surgical skin tightening and fat reduction (with radiofrequency energy, cold treatment, or ultrasound). These noninvasive treatments do not even break the skin, and are applied on top of the skin Then we have minimally invasive procedures, which include those that just barely break the skin, but are like getting a shot, and don’t require cutting and sewing the skin as in traditional surgery. These minimally invasive procedures include filler and neuromodulator injections to fill out the sagging aging face while reducing lines and wrinkles, as well as liposuction through tiny openings to suck out excess fat. All of these procedures and many more are available but if you do want to have a cosmetic procedure then make sure you seek out a reputable cosmetic surgeon such as Lisa Rush. In the old days, cosmetic treatments meant getting traditional plastic surgery, like a face lift or tummy tuck. These required general anesthesia, cutting and sewing the skin, significant risk of scarring, and days to weeks of recovery time. More recently, dermatologists have pioneered noninvasive and minimally invasive procedures, such as those I just described, which provide many of the same benefits as traditional plastic surgery without the risk, scars, and downtime, for example, somewhere like Rhinoplasty NYC talk about Rhinoplasties with noninvasive methods. Now these minimally invasive and noninvasive treatments have become more popular than traditional cosmetic surgery. (more…)
Author Interviews, ENT, JAMA, NIH / 17.08.2018

MedicalResearch.com Interview with: “Bad smell” by Brian Fitzgerald is licensed under CC BY 2.0Kathleen Bainbridge, PhD Epidemiology and Biostatistics Program NIDCD MedicalResearch.com: What is the background for this study? What are the main findings? Response: The causes of phantom odor perception are not understood. This study looked for the prevalence and risk factors for this disorder. We found that that 1 in 15 Americans (or 6.5 percent) over the age of 40 experiences phantom odors. This study, is the first in the U.S. to use nationally representative data to examine the prevalence of and risk factors for phantom odor perception. The study included about 7,400 adults who participated in the National Health and Nutrition Examination Survey, a continuous survey conducted by the National Center for Health Statistics which is part of the Centers for Disease Control and Prevention. The study could inform future research aiming to unlock the mysteries of phantom odors. We identified risk factors that may be related to the perception of phantom odors. People are more likely to experience this condition if they are female, and are relatively young—we found a higher prevalence in 40-60 year-olds compared to 60+ year-olds. Other risk factors include head injury, dry mouth, poor overall health, and low socio-economic status. People with lower socio-economic status may have health conditions that contribute to phantom odors, either directly or because of medications needed to treat their health conditions. (more…)
Author Interviews, Blood Pressure - Hypertension, JAMA, Pharmacology / 17.08.2018

MedicalResearch.com Interview with: Dr Ruth Webster PhD, BMedSc(hons), MBBS(hons), MIPH(hons) Head, Research Programs, Office of the Chief Scientist Senior Lecturer, Faculty of Medicine UNSW Sydney The George Institute for Global Health Australia MedicalResearch.com: What is the background for this study? What are the main findings?  Response: We know from previous research that 80% of the blood pressure lowering efficacy of any medication occurs in the first half of the dose whilst most side effects occur at higher doses. We also know that most people will require at least 2 blood pressure lowering medications to reach their target blood pressure and that combining multiple pills into one combination medication helps patients take their medication more reliably. There was therefore good evidence to believe that using three half strength doses in one pill would be better than usual care in helping patients to achieve their blood pressure targets. We showed that, compared with patients receiving usual care, a significantly higher proportion of patients receiving the Triple Pill achieved their target blood pressure of 140/90 or less (with lower targets of 130/80 for patients with diabetes or chronic kidney disease). It's estimated more than a billion people globally suffer from high blood pressure with the vast majority having poorly controlled blood pressure. Our results could help millions of people globally reduce their blood pressure and reduce their risk of heart attack or stroke. (more…)
Author Interviews, Cancer Research, CT Scanning, JAMA, Lung Cancer / 16.08.2018

MedicalResearch.com Interview with: “CT Scan” by frankieleon is licensed under CC BY 2.0Dr. Bruno Heleno MD PhD Assistant Professor | Professor Auxiliar NOVA Medical School | Faculdade de Ciências Médicas Universidade Nova da Lisboa  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The Danish Lung Cancer Screening Trial (DLCST) is a randomized controlled trial which enrolled 4104 participants (aged 50-70 years; current or former smokers; ≥20 pack years; former smokers must have quit <10 years before enrollment) to either 5 rounds of screening for lung cancer with low-dose CT-scans or to no screening. After 10 years of follow-up, there was a 2.10 percentage points lung cancer absolute risk increase with low-dose CT-screening. Overdiagnosis, i.e. the detection of cancer that would not progress to symptoms or death, was estimated at 67.2% of the screen-detected cancers. (more…)
Author Interviews, Critical Care - Intensive Care - ICUs, JAMA, Pulmonary Disease / 15.08.2018

MedicalResearch.com Interview with: Hayley B. Gershengorn, MD Division of Pulmonary, Allergy, Critical Care, and Sleep Medicine, Department of Medicine, Leonard M. Miller School of Medicine, University of Miami, Miami, Florida Division of Critical Care Medicine, Department of Medicine, Albert Einstein College of Medicine, Bronx, New York MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Beginning in December, 2011, professional guidelines have recommended against the practice of daily chest radiography (CXRs) for mechanically ventilated patients.  However, we hypothesized that this practice was still commonplace in the US and varied from hospital to hospital. To address this question, we performed a retrospective cohort study of >500,000 mechanically ventilated adults across 416 US hospitals. We found that 63% of these patients received daily CXRs and that, while use has been decreasing, this decrease is small (a 3% relative reduction in the odds of daily CXR receipt per discharge quarter starting in 2012). Moreover, the hospital at which a patient received care greatly impacted the likelihood of daily CXR receipt. (more…)
Author Interviews, Breast Cancer, JAMA, Radiation Therapy / 14.08.2018

MedicalResearch.com Interview with: Steven Narod, MD, FRCPC, FRSC Senior Scientist, Women’s College Research Institute Director, Familial Breast Cancer Research Unit, Women's College Research Institute Professor, Dalla Lana School of Public Health, University of Toronto Professor, Department of Medicine Tier 1 Canada Research Chair in Breast Cancer University of Toronto MedicalResearch.com: What is the background for this study? What are the main findings?  Response: In the past we have shown that about 3 percent of women with ductal carcinoma in situ (DCIS) will die of breast cancer within 20  years of diagnosis.   In the current study, we took a very close look at how the different treatments impact on the risk of dying of breast cancer. Women with DCIS are at risk for  both a new cancer within the breast and dying of breast cancer from cells that spread beyond the breast (lung, liver, brain and bone).   About 20% of DCIS patients will get a new breast cancer within the breast at 20 years.
  • We show here that it is not necessary to develop a new cancer within the breast to die of breast cancer,  in some cases the DCIS spreads directly in the absence of local recurrence.
  • We show that radiotherapy can prevent 25% of the deaths from breast cancer after DCIS. And this has nothing to do with local recurrence.
  • We show that mastectomy reduces the chance of a getting a new cancer (local recurrence) but  doesn’t reduce the chance of dying of breast cancer.
So, if the goal is to prevent new cancers in the breast -   then mastectomy is the best treatment If the goal is to prevent the woman from dying of breast cancer - then radiotherapy is the best treatment.  (more…)
Author Interviews, Global Health, JAMA, Pediatrics / 13.08.2018

MedicalResearch.com Interview with: Chunling Lu, PhD Director, Program in Global Health Economics and Social Change Assistant Professor in Global Health and Social Medicine Division of Global Health Equity, Brigham and Women's Hospital Department of Global Health and Social Medicine, Harvard Medical School Harvard Center for Population and Development Studies Institute for Quantitative Social Science, Harvard University Boston, MA 02115 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Today, we have the largest generation of youth (10-24 years) in human history (1·8 billion) and about 90% of them live in low- and middle-income countries.  Healthy growth and learning during the adolescent years underpins future population health and productivity. The importance of adolescent health has now been recognized with the inclusion of adolescents in the 2015 Every Woman, Every Child agenda through the Global Strategy for Women’s Children’s and Adolescents’ Health. A capacity to finance health care has underpinned progress in most areas of health. In poorer countries much of that financing comes from global donors. As little is known about donors’ contribution to adolescent health, our study fills in that knowledge gap by assessing how much development assistance has been disbursed to projects for adolescent health in 132 developing countries between 2003 and 2015. We found that donors’ contribution to the projects targeting adolescent health cumulatively accounted for only 1.6% of development assistance for health. Among the top 10 leading causes of disability adjusted life years (DALYs) in adolescents, sexual, reproductive health and HIV/AIDS received the largest donors’ contribution (approximately 68% during the study period), followed by interpersonal violence, tuberculosis, and diarrheal diseases. Other major causes of disease burden, including anemia, road injuries, and depressive disorders, have been largely overlooked by donors.  (more…)
Author Interviews, Heart Disease, JAMA / 10.08.2018

MedicalResearch.com Interview with: Seth Landefeld, M.D.  Dr. Landefeld is chairman of the department of medicine and the Spencer chair in medical science leadership at the University of Alabama at Birmingham (UAB) School of Medicine. Dr. Landefeld also serves on the board of directors of the American Board of Internal Medicine, the UAB Health System, and the University of Alabama Health Services Foundation. MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by atrial fibrillation and whom it primarily affects? Response: Atrial fibrillation—or AF—is an irregular heartbeat. AF affects nearly 3 million Americans and is a leading cause of stroke. Older age and obesity increase the risk of AF, and the condition also occurs more in men than in women. With an aging society and the growing prevalence of obesity in the U.S., this was an important topic for the U.S. Preventive Services Task Force to review. The Task Force looked at the latest research to see if screening for atrial fibrillation using electrocardiography—or ECG, which is a test that records the activity of someone’s heart—to supplement traditional care is an effective way to diagnose AF and prevent stroke. We found that more research is needed to determine if screening with ECG can help to identify AF and prevent stroke in adults who are 65 and older and do not have signs or symptoms of the disease.  (more…)
Author Interviews, Biomarkers, Cancer Research, Gastrointestinal Disease, JAMA / 10.08.2018

MedicalResearch.com Interview with: Wei Zhang, Ph.D. Hanes and Willis Family Professor in Cancer Director Cancer Genomics and Precision Oncology Wake Forest Baptist Comprehensive Cancer Center Winston-Salem, NC  27157-1082 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Gastric cancer is a leading cause of cancer-related death worldwide. Infection by the Helicobacter pylori is the major cause of gastric cancer, which accounts for more than 60% of cases. Despite progress in helicobacter pylori eradication and early cancer diagnosis, the five-year survival rate of gastric cancer remains less than 30%. Gastric cancer is one of the most common cancer types in Asia but the incidence for gastric cancer has seen a steadily increase in the United States in recent years. Immunotherapy treatment has shown remarkable benefit for some cancer patients whereas others experience toxicities. It is important to identify markers that help oncologists decide which patient would benefit from this promising new treatment strategy. It has been suggested that gastric cancer that is positive for Epstein-Barr Virus is likely more responsive to immunotherapy but only about 10% of gastric cancer patients belong to this category. More potential markers are urgently needed for clinical practice. There is accumulating evidence that high tumor mutation load, which means there are high numbers of gene mutations in the tumor, can provide a signal to activate immune response systems thus rendering tumors more sensitive to immunotherapy.

Author Interviews, Diabetes, JAMA, PTSD, Weight Research / 09.08.2018

MedicalResearch.com Interview with: Jeff Scherrer, Ph.D. Associate professor; Research director Department of Family and Community Medicine Saint Louis University Center for Health Outcomes Research  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The rationale for this study comes from evidence that patients with PTSD are more likely to be obese than persons without PTSD and have more difficulty losing weight. Given the obesity epidemic and substantial role of obesity in risk of type 2 diabetes, we sought to determine if obesity accounted for the existing evidence that PTSD is a risk factor for incident type 2 diabetes.  Other studies have adjusted for obesity or BMI in models that control for obesity/BMI and other confounders simultaneously which prohibits measuring the independent role of obesity on the ass (more…)
Author Interviews, Dental Research, JAMA, Opiods / 09.08.2018

MedicalResearch.com Interview with: Calista Harbaugh, MD House Officer, General Surgery Clinician Scholar, National Clinician Scholars Program Research Fellow, Michigan Opioid Prescribing Engagement Network University of Michigan MedicalResearch.com: What is the background for this study? What are the main findings? Response: Wisdom tooth extractions is one of the most common procedures among teens and young adults, with more than 3.5 million young people having wisdom teeth pulled every year. This procedure is commonly paired with a prescription for opioid pain medication. As the opioid epidemic sweeps the nation, we must pay attention to the long term effects of opioid prescribing for even routine procedures. This is particularly important for wisdom tooth extraction where there is evidence that opioid pain medications may be no more effective than anti-inflammatories alone. Using commercial insurance claims, we evaluated the association between receiving an opioid prescription with wisdom tooth extraction and developing new persistent opioid use in the year after the procedure. We found nearly a 3-fold increase in odds of persistent opioid use, attributable to whether or not an opioid was prescribed. This translates to nearly 50,000 young people developing new persistent opioid use each year from routine opioid prescribing for wisdom tooth extraction. (more…)

MedicalResearch.com Interview with: Ian M. Paul, M.D., M.Sc. Professor of Pediatrics and Public Health Sciences Chief, Division of Academic General Pediatrics Vice Chair of Faculty Affairs, Department of Pediatrics Penn State College of Medicine Hershey, PA 17033-0850 MedicalResearch.com: What is the background for this study? What are the main findings? Response: 20-25% of 2-5 year old children are overweight or obese in the US, and these children have increased risk of remaining overweight across the lifecourse. To date, research efforts aimed at preventing early life overweight have had very limited success. In our randomized clinical trial that included 279 mother-child dyads, a responsive parenting intervention that began shortly after birth significantly reduced body mass index z-score compared with controls at age 3 years.

Author Interviews, JAMA, NEJM, OBGYNE, University Texas / 09.08.2018

MedicalResearch.com Interview with: George R. Saade, MD Professor Jennie Sealy Smith Distinguished Chair Professor, Obstetrics & Gynecology, and Cell Biology Chief of Obstetrics and Maternal Fetal Medicine Director, Perinatal Research Division Department of Obstetrics and Gynecology Division of Maternal Fetal Medicine UTMB at Galveston MedicalResearch.com: What is the background for this study? Response: Several analyses show that the lowest risk to the baby is if delivered at 39 weeks. As pregnancy goes beyond 39 weeks, the risk to the baby increases. On the other hand, the general belief was that induction of labor at 39 increases the risk of cesarean and may not be good for the baby. The guideline were that induction without medical indication, or what we call elective induction of labor, should not be done. However, the studies on which this belief was based were not appropriately designed or analyzed. These studies compared women who were induced at 39 weeks to those who had spontaneous labor at 39 weeks. This comparison is not appropriate. While induction is a choice, having spontaneous labor at 39 weeks is not by choice.  So the correct comparison should be between women who were induced at 39 weeks to those who were not induced and continued their pregnancy beyond 39 weeks. In other words, they continued until they had spontaneous labor or developed an indication to be delivered (expectantly managed). That is how the study was done. First time pregnant women were randomized between these 2 options. The reason the study was done in first time mothers is that they have the highest risk of cesarean compared with women who had delivered vaginally before. (more…)
Author Interviews, Columbia, JAMA, Mental Health Research / 09.08.2018

MedicalResearch.com Interview with: Priya Wickramaratne PhD Associate Professor of Clinical Biostatistics (in Psychiatry) Department of Psychiatry, College of Physicians and Surgeons Columbia University New York State Psychiatric Institute New York MedicalResearch.com: What is the background for this study? Response: Approximately 12% of adolescents in the United States report having thoughts about attempting suicide. Moreover, suicide is a primary cause of death among females 15 to 19 years of age. Religious and spiritual beliefs have received little attention in previous research examining risk and protective factors of child and adolescent suicide. This study used data from a three-generation study of 214 children and adolescents from 112 nuclear families whose parents were at high or low risk for major depressive disorder to study the association of children and parent’s religious beliefs with risk of suicidal behavior in the children.

Author Interviews, Brigham & Women's - Harvard, Education, Gender Differences, JAMA, Surgical Research / 09.08.2018

MedicalResearch.com Interview with: Erika L. Rangel, MD,MS Instructor, Harvard Medical School Trauma, Burn and Surgical Critical Care Department of Surgery, Center for Surgery and Public Health Brigham and Women’s Hospital Harvard T. H. Chan School of Public Health Boston, Massachusetts MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Although women make up half of medical student graduates in 2018, they only comprise a third of applicants to general surgery. Studies suggest that lifestyle concerns and perceptions of conflict between career and family obligations dissuade students from the field. After entering surgical residencies, women residents have higher rates of attrition (25% vs 15%) and cite uncontrollable lifestyle as a predominant factor in leaving the field. Surgeons face reproductive challenges including stigma against pregnancy during training, higher rates of infertility, need for assisted reproduction, and increased rates of pregnancy complications. However, until recently, studies capturing the viewpoints of women who begin families during training have been limited. Single-institution experiences have described mixed experiences surrounding maternity leave duration, call responsibilities, attitudes of coworkers and faculty, and the presence of postpartum support. Earlier this year, our group presented findings of the first national study of perspectives of surgical residents who had undergone pregnancy during training. A 2017 survey was distributed to women surgical residents and surgeons through the Association of Program Directors in Surgery, the Association of Women Surgeons and through social media via twitter and Facebook. Responses were solicited from those who had at least one pregnancy during their surgical training. 39% of respondents had seriously considered leaving surgical residency, and 30% reported they would discourage a female medical student from a surgical career, specifically because of the difficulties of balancing pregnancy and motherhood with training (JAMA Surg 2018; July 1; 153(7):644-652). These findings suggested the challenges surrounding pregnancy and childrearing during training may have a significant impact on the decision to pursue or maintain a career in surgery. The current study provides an in-depth analysis of cultural and structural factors within residency programs that influence professional dissatisfaction. We found that women who faced stigma related to their pregnancies, who had no formal maternity leave at their programs, and who altered subspecialty training plans due to perceived challenges balancing motherhood with the originally chosen subspecialty were most likely to be unhappy with their career or residency.

MedicalResearch.com Interview with: Shari Barkin, MD, MSHS William K. Warren Foundation Endowed Chair Professor of Pediatrics Division Chief of Academic General Pediatrics Director of Pediatric Obesity Research Vanderbilt University Medical Center MedicalResearch.com: What is the background for this study? Response: Obesity often begins in childhood and disproportionately affects some populations, including underserved children. Given the challenges associated with achieving effective obesity treatment, the focus needs to be on prevention and needs to start early. Barkin et al conducted the longest behavioral intervention obesity prevention trial with 610 underserved parent-preschool child pairs, testing a three-year pragmatic approach that focused on families based in the communities in which they lived, and partnering with both Metro Parks and Recreation and the Nashville Public Library Foundation. Eligible children were high normal weight or overweight but not obese and lived in neighborhoods with access to neighborhood built environments that included parks and recreation and library branches.  (more…)
Author Interviews, Critical Care - Intensive Care - ICUs, Exercise - Fitness, JAMA / 08.08.2018

MedicalResearch.com Interview with: “cycling” by Urs Steiner is licensed under CC BY 2.0Guillaume Fossat, Physiotherapist and Thierry Boulain, M.D. Médecine Intensive Réanimation Centre Hospitalier Régional Orléans, France MedicalResearch.com: What is the background for this study? Response: Critically ill patients may suffer terrific muscle wasting during their intensive care unit stay. In most patients, particularly those with sepsis or other high inflammatory states, this is due to proteolytic pathways runaway that may persist as long as the cause of inflammation has not been eliminated. What is more, forced rest, as the one imposed to severely ill patients who need sedation to tolerate artificial respiratory support also induces muscle deconditioning and mass loss. In short, the more you are severely and acutely ill, the more you breakdown your muscle proteins and use the catabolic byproducts to fuel the rest of your organism. As a result of this sort of autophagy, intensive care unit survivors may have lost tens of muscle mass kilograms at discharge, to the point that they have lost all or parts of their functional autonomy. The personal and social burden is considerable as muscle weakness may persist several years after hospital discharge. In the 2000’s, physiotherapy and early rehabilitation during intensive care have emerged as a way to counteract the autophagic muscle wasting and help patients to speed up their return to functional autonomy. Therefore, a standardized early rehabilitation that consists in early muscle exercises, systematic lowering or interruption of sedative drugs dosages to allow prompt patient’s awaking, early transfer to chair and early first walk try, has become the standard of care. However, to what extent, when and how muscles should be exercised during the intensive care unit stay in order to optimize the positive effects of rehabilitation remains a nearly blank clinical research area. In-bed leg cycling and electrical muscle stimulation, each for their part, have shown encouraging results. In our study, we sought to know if the very early combination of both could improve global muscle strength in survivors at intensive care unit discharge. (more…)

Santos-Lozada Director, Graduate Program in Applied Demography Assistant Teaching Professor, Department of Sociology and Criminology Research Affiliate, Population Research Institute College of Liberal Arts Penn State University MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Dr. Howard and I have been working on the topic of deaths attributable to Hurricane Maria since November, and provided rapid-response estimates by the end of November about the humanitarian crisis experienced by Puerto Ricans following the Hurricane. Our main findings are that there are approximately 1,139 deaths in excess of historical patterns between September, October and November in Puerto Rico. (more…)

The research question was; Does HPV status of Barrett’s high-grade dysplasia and esophageal adenocarcinoma influence survival as in viral positive head and neck cancers? We therefore sought to determine the prognostic significance of esophageal tumor HPV status and associated viral transcriptional markers (E6/E7 mRNA and p16INK4A) and TP53. (more…)

MedicalResearch.com Interview with: Dr. Angela Sauaia, MD, PhD Professor of Public Health and Surgery University of Colorado Denver Statistical Editor, Journal of Trauma and Acute Care Surgery Statistical Consultant, Department of Surgery Denver Health Medical Center  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: As injury researchers we monitor national trends in injury. The CDC WISQARS (Web-based Injury Statistics Query and Reporting System) is one of the few available open sources of injury data we can use. During the 1980’s and 1990’s, we saw much improvement in deaths due to most injury mechanisms, such as car accidents fatalities. Our study shows, however, that recent trends seem to be eroding these promising survival gains. Both violent and unintentional injuries alike seem to be increasing, especially since 2014. We are unclear about the causes of this recent increase in trauma-related deaths, but it is an alarming trend. (more…)

MedicalResearch.com Interview with: Marc S. Sabatine, MD, MPH Chairman | TIMI Study Group Lewis Dexter, MD, Distinguished Chair in Cardiovascular Medicine Brigham and Women's Hospital Professor of Medicine | Harvard Medical School MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Low-density lipoprotein cholesterol (LDL-C) is a well-established risk factor for cardiovascular disease. The initial statin trials studied patients with high levels of LDL-C, and showed a benefit by lowering LDL-C. We and others did studies in patients with so-called “average” levels of LDL-C (120-130 mg/dL), and also showed clinical benefit with lowering. (more…)

MedicalResearch.com Interview with: “Doctors with patient, 1999” by Seattle Municipal Archives is licensed under CC BY 2.0Dr. Laura M. Mazer, MD Goodman Surgical Education Center Department of Surgery Stanford University School of Medicine Stanford, California MedicalResearch.com: What is the background for this study? What are the main findings?  Response: There are numerous articles that clearly document the high prevalence of mistreatment of medical trainees. We have all seen and experienced the results of an “I’ll do unto you like they did unto me” attitude towards medical education. Our motivation for this study was to go beyond just documenting the problem, and start looking at what people are doing to help fix it. Unfortunately, we found that there are comparatively few reports of programs dedicated to preventing or decreasing mistreatment of medical trainees. In those studies we did review, the study quality was generally poor. Most of the programs had no guiding conceptual framework, minimal literature review, and outcomes were almost exclusively learner-reported. (more…)
Author Interviews, Cost of Health Care, JAMA, Medicare, UCSF / 01.08.2018

MedicalResearch.com Interview with: Andrew B. Bindman, MD Professor of Medicine PRL- Institute for Health Policy Studies University of California San Francisco MedicalResearch.com: What is the background for this study?   Response: The purpose of this study was to evaluate the use and impact of a payment code for transitional care management services which was implemented by Medicare in. The transition of patients from hospitals or skilled nursing facilities back to the community often involves a change in a patient’s health care provider and introduces risks in communication which can contribute to lapses in health care quality and safety. Transitional care management services include contacting the patient within 2 business days after discharge and seeing the patient in the office within 7-14 days. Medicare implemented payment for transitional care management services with the hope that this would increase the delivery of these services believing that they could reduce readmissions, reduce costs and improve health outcomes.

Author Interviews, JAMA, Rheumatology, Statins / 31.07.2018

MedicalResearch.com Interview with: Dr Gillian E. Caughey PhD Senior Research Fellow | School of Medicine Discipline of Pharmacology THE UNIVERSITY OF ADELAIDE Australia MedicalResearch.com: What is the background for this study? What are the main findings? Response: Statins are one of the most commonly prescribed medications worldwide.  Muscular adverse effects (myalgia and myopathy) are well recognised adverse effects and symptoms resolve with cessation of statins. Idiopathic inflammatory myositis (IIM) is a heterogeneous group of autoimmune myopathies that may also be associated with statin use. IIM does not resolve with cessation of statin therapy, requires treatment with immunosuppressive agents and is a severe, debilitating condition. To date, there have been no epidemiological studies examining exposure to statins and the association of histologically confirmed IIM. In our case control study of 221 cases o fIdiopathic inflammatory myositis, there was an almost 2-fold increased likelihood of statin exposure in patients with IIM compared with controls (adjusted odds ratio, 1.79; 95%CI, 1.23-2.60). After observing a significant association of statin exposure with IIM, we conducted a sensitivity analysis where we excluded those patients with necrotizing myositis as recent studies have reported this type of IIM to be associated with statin use and the presence of autoantibodies against HMG-CoA reductase. Exclusion of these specific cases from the analysis did not change our study findings and an increased risk of Idiopathic inflammatory myositis with statin exposure remained (adjusted OR, 1.92; 95% CI, 1.29-2.86).  This suggest the potential association of all types of Idiopathic inflammatory myositis with statin exposure.

What are the main findings?  Response: Allogeneic bone marrow transplantation BMT is used with a curative intent for life-threatening malignant and non-malignant diseases of childhood. In this observational study, we describe the late mortality experienced by children undergoing BMT over the past 3 decades. Our cohort included 1388 BMT recipients who had undergone allogeneic BMT between 1974 and 2010 and survived 2 or more years. We found that, conditional on surviving the first 2 years after bone marrow transplantation, the probability of surviving an additional 20 years approached 80%. Risk of dying from non-relapse-related causes exceeded the risk of dying from relapse-related causes. The leading non-relapse-related causes of death were infection (with or without graft vs. host disease) and new cancers. Overall, the cohort was at a 14-fold greater risk of dying as compared with the general population (of similar age and sex). Further, this excess risk remained elevated even among those who had survived 25 years. On a positive note, the risk of late mortality has continued to decline over the past 3 decades.  (more…)

MedicalResearch.com Interview with: “GUNS” by Jessica Spengler is licensed under CC BY 2.0Kendrin R. Sonneville, ScD, RD Assistant Professor Department of Nutritional Sciences University of Michigan School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: The results from this come out of MyVoice, a text message cohort of youth ages 14-24 representing every state in the country (http://hearmyvoicenow.org/). Each week we ask the youth in our cohort a series of open-ended to questions, with the goal of gathering the real-time opinions and experiences of youth across the U.S. This study reports the results of questions we asked MyVoice paritpatns between 07/2017 and 01/2018 about guns and gun control.  (1) What are your thoughts about having guns in your home? (2) Do you think gun control laws would affect mass shootings? Why? (3) Who, if anyone, should NOT be allowed to own guns? We found that about one-third of youth in our diverse sample were “against” guns in the home, and the remaining two-thirds were either “pro” or “conditionally pro” guns in the home, stating that gun ownership is acceptable under certain conditions, such as proper storage, or kept away from children. Youth in our sample largely believed that gun control laws could decrease mass shootings, but one-third felt that gun control laws would not be enough to impact mass shootings. (more…)

MedicalResearch.com Interview with: Jianning Zhang MD, Ph.D Chairman, II, VII Chinese Medical Association of Neurosurgery President, Tianjin Medical University General Hospital, China  Jianning Zhang MD, Ph.D Chairman, II, VII Chinese Medical Association of Neurosurgery President, Tianjin Medical University General Hospital, China   MedicalResearch.com: What is the background for this study? Response: The elderly population is growing dramatically world widely, especially in China. The incidence of chronic subdural hematoma has been rising over the past years. Although the surgery is not a difficult process, the risk of death and recurrence persist, and the affliction and economic expenditure of the patients are relatively higher in the elderly. For these reasons, it is urgent to develop novel pharmacological therapies with sufficient safety and efficacy.  It has been known that the high expression of VEGF and inflammatory factors in chronic subdural hematoma can lead to abundant angiogenesis of immature vessels on the wall of hematoma. In our previous study, patients with chronic subdural hematoma have impaired ability to promote vascular maturation. For example, the number of endothelial progenitor cells in circulating blood is about 67% of the healthy individuals with similar age.  Atorvastatin can mobilize endothelial progenitor cells to reduce inflammation. It increases the number of circulating endothelial cells that are inversely correlated with the volume of hematoma. We have demonstrated that atorvastatin can promote endothelial cell formation and reduce the leakage of endothelial cell barrier in vitro. Results from in vivo experiments in animal models of subdural hematoma suggest that atorvastatin can promote the maturation of blood vessels and reduce inflammation on the margin of hematoma, and thus improve the neurological outcome.

MedicalResearch.com Interview with: Manali Patel MD MPH Assistant Professor of Medicine, Oncology Stanford Palo Alto Veterans Affairs Health Care System   MedicalResearch.com: What is the background for this study? What are the main findings?  Response: In prior work, many patients with advanced stages of cancer report a lack of understanding of their prognosis and receipt of care that differs from their preferences. These gaps in care delivery along with the unsustainable rise in healthcare spending at the end-of-life and professional healthcare provider shortages led our team to consider new ways to deliver cancer care for patients.  Based on input from focus groups with patients, caregivers, oncology care providers and healthcare payers, we designed a novel model of cancer care to address these gaps in care delivery.  The intervention consisted of a well-trained lay health worker to assist patients with understanding and communicating their goals of care with their oncology providers and caregivers. We found that patients who received the six-month intervention reported greater satisfaction with the care they received and their decision-making, had higher rates of hospice use, lower acute care use, and 95% lower total healthcare expenditures in the last month of life.  The intervention resulted in nearly $3 million dollars in healthcare savings.
