MedicalResearch.com Interview with: Annetine C. Gelijns, PhD Professor and System Chair Population Health Science and Policy Icahn School of Medicine at Mount Sinai Alan J Moskowitz, MD Professor of Population Health Science and Policy Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? Where do these mesenchymal cells come from?  Response: Implantable LVADs significantly improve the survival and quality of life of advanced heart failure patients. However, these devices are associated with substantial adverse events, including infection and thromboembolic events. Moreover, whereas these devices improve myocardial function, few patients recover sufficient function to be explanted from their LVAD. These observations have focused attention on stem cells as a possible adjunctive therapy to further augment cardiac recovery. Mesenchymal precursor cells (MPCs), which are obtained from healthy donors and culture-expanded, have been shown in animal and early human studies to improve cardiac function. Using temporary weaning as a signal of cardiac recovery, we conducted an exploratory trial in the Cardiothoracic Surgical Trials Network (CTSN), which found that MPCs increased the probability of temporary weaning from full LVAD support compared to sham-control patients. Therefore, this signal of efficacy led the CTSN to design our current follow-up trial evaluating the efficacy and safety of a higher dose of MPCs in LVAD patients. (more…)

MedicalResearch.com Interview with: Dennis P. Wall, PhD Associate Professor Departments of Pediatrics, Psychiatry (by courtesy) and Biomedical Data Science Stanford University  MedicalResearch.com: What did we already know about the potential for apps and wearables to help kids with autism improve their social skills, and how do the current study findings add to our understanding? What’s new/surprising here and why does it matter for children and families?  Response: We have clinically tested apps/AI for diagnosis (e.g.  https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1002705) in a number of studies. This RCT is a third phase of a phased approach to establish feasibility and engagement through in-lab and at-home codesign with families with children with autism. This stepwise process is quite important to bring a wearable form of therapy running AI into the homes in a way that is clinically effective. What’s new here, aside from being a first in the field, is the rigorous statistical approach we take with an intent-to-treat style of analysis. This approach ensures that the effect of the changes are adjusted to ensure that any significance observed is due to the treatment.  Thus, with this, it is surprising and encouraging to see an effect on the VABS socialization sub-scale. This supports the hypothesis that the intervention has a true treatment effect and increases the social acuity of the child. With it being a home format for intervention that can operate with or without a clinical practitioner, it increases options and can help bridge gaps in access to care, such as when on waiting lists or if the care process is inconsistent.   (more…)

MedicalResearch.com Interview with: Edward Bell, MD Vice Chair for Faculty Development Department of Pediatrics Professor of Pediatrics - Neonatology Carver College of Medicine University of Iowa Health Care  MedicalResearch.com: What is the background for this study? Response: The study is an analysis of what happened to the 205 babies with birth weigh below 400 grams and gestational age of 22 through 26 weeks who were born between 2008 and 2016 at 21 academic medical centers that are members of the National Institute of Child Health and Human Development Neonatal Research Network. The Network exists to collaborate in finding ways to improve the survival and health of premature and other critically-ill newborn infants. 400 grams is very small. By comparison, 1 pound is 454 grams. (more…)
Author Interviews, Dermatology, JAMA, Pediatrics, Sleep Disorders, UCSF / 26.03.2019

MedicalResearch.com Interview with: Dr. Katrina Abuabara, MD, MA, MSCE Department of Dermatology Program for Clinical Research, University of California, San Francisco MedicalResearch.com: What is the background for this study? Response: The wellbeing and development of children is strongly influenced by parents’ physical and psychosocial health. Parents of children with chronic illness, in particular, are susceptible to poor sleep, and previous studies have found major sleep impairments among parents of children with ventilator dependency and cystic fibrosis, but few studies have examined sleep patterns among parents of children with more common chronic illnesses like atopic dermatitis (also known as eczema).

Author Interviews, Gender Differences, JAMA, Pediatrics / 25.03.2019

MedicalResearch.com Interview with: Dr. David Klein MD MPH Associate Program Director National Capital Consortium (NCC) Family Medicine Residency Fort Belvoir Community Hospital Dr. Elizabeth Hisle-Gorman MSW, PhD Assistant Professor, Uniformed Services University  MedicalResearch.com: What is the background for this study?  Response: Our study, “Transgender Children and Adolescents Receiving Care in the U.S. Military Healthcare System: A Descriptive Study,” sought to analyze the number of military dependent children and adolescents who have a transgender or gender-diverse identity and receive medical care in the Military Health System (MHS), recognizing that the number has been increasing, but not knowing to what extent. Ultimately, in studying this data, we hoped to document the needs of transgender children in military families to support provision of adequate and appropriate high-quality care. (more…)
Author Interviews, Health Care Systems, JAMA / 24.03.2019

MedicalResearch.com Interview with: Maryam Guiahi, MD Associate Professor, Ob/Gyn School of Medicine University of Colorado  MedicalResearch.com: What is the background for this study? Response: The United States Conference of Catholic Bishops expects providers in Catholic Health Care Facilities to follow the Ethical and Religious Directives for Catholic Health Care Services, which places limits on reproductive and end-of-life care. Prior research has demonstrated that many patients do not anticipate religious health care restrictions, yet often face conflicts in care. We were interested in whether Catholic hospitals disclose their religious affiliation and explain to patients how this affiliation may impact the care they are offered. (more…)
Author Interviews, Duke, Heart Disease, JAMA / 21.03.2019

MedicalResearch.com Interview with: Renato D. Lopes MD, MHS, PhD Professor of Medicine Division of Cardiology Duke University Medical Center Duke Clinical Research Institute Alexander C. Fanaroff, MD, MHS Division of Cardiology and Duke Clinical Research Institute Duke University, Durham, North Carolina MedicalResearch.com: What is the background for this study? What are the main findings? Response: About ten years ago, a group of researchers examined the evidence supporting guideline recommendations in cardiology for the first time. Quite surprisingly, they found that only 11% of recommendations in American College of Cardiology/American Heart Association (ACC/AHA) guidelines were supported by evidence from randomized controlled trials, the highest level of evidence. The researchers called for greater collaboration among investigators and funders in identifying key research questions, development of streamlined clinical trial methods, and expansion of funding for clinical research. Over the past 10 years, some of these steps have been taken, but it is unclear how the evidence supporting guideline recommendations has changed. We therefore analyzed the 51 current cardiovascular guideline documents -- 26 from the ACC/AHA and 25 from the European Society of Cardiology (ESC) -- including 6,329 recommendations. Overall, 8.5% of recommendations in ACC/AHA guidelines and 14.3% of recommendations in ESC guidelines were supported by evidence from randomized controlled trials. When looking specifically at guidelines that have been updated, we found no significant changes in the proportion of recommendations supported by evidence from randomized controlled trials. (more…)
Author Interviews, Brigham & Women's - Harvard, Critical Care - Intensive Care - ICUs, End of Life Care, JAMA / 21.03.2019

MedicalResearch.com Interview with: Joanna Paladino, MD Director of Implementation, Serious Illness Care Program | Ariadne Labs Brigham and Women's Hospital | Harvard T.H. Chan School of Public Health Palliative Care | Dana-Farber Cancer Institute Instructor | Harvard Medical School and Dr. Rachelle Bernacki MD MS Director of Quality Initiatives Psychosocial Oncology and Palliative Care Senior Physician, Assistant Professor of Medicine Harvard Medical School Dr. Paladino's responses: MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Paladino: People living with serious illness face many difficult decisions over the course of their medical care. These decisions, and the care patients receive, should be guided by what matters most to patients, including their personal values, priorities, and wishes. These conversations don’t often happen in clinical practice or do so very late in the course of illness, leaving patients exposed to getting care they don’t want. Doctors and nurses want to have these important discussions, but there are real challenges, including insufficient training and uncertainties about when and how to start the conversation. We designed an intervention with clinical tools, clinician training, and systems-changes to address these challenges. When tested in a randomized clinical trial in oncology, we found that the intervention led to more, earlier, and better conversations between oncology clinicians and their patients with life-limiting cancer. These findings demonstrate that it is possible to ensure reliable, timely, and patient-centered serious illness conversations in an outpatient oncology practice. (more…)
Author Interviews, Cancer Research, JAMA / 21.03.2019

MedicalResearch.com Interview with: Peter R. Dixon, MD Department of Otolaryngology-Head & Neck Surgery Institute of Health Policy, Management and Evaluation University of Toronto Toronto, Ontario, Canada  MedicalResearch.com: What is the background for this study? Response: The word ‘cancer’ is often associated with an aggressive and lethal disease. Innovations in screening and diagnostic tests detect some ‘cancers’ that -- even if left untreated -- pose very low-risk of any symptoms, progression, or mortality. Still, many of these low-risk cancers are treated aggressively and those treatments can have harmful consequences and side-effects. We were interested in determining how influential the word ‘cancer’ is in decisions made by patients about low-risk malignant neoplasms relative to other labels for the same disease. (more…)
Author Interviews, Heart Disease, JAMA / 19.03.2019

MedicalResearch.com Interview with: Dr. Carina Blomström-Lundqvist, MD Professor of Cardiology Department of Cardioloy Institution of Medical Science Uppsala, Sweden MedicalResearch.com: What is the background for this study?   Response: While all previous trials comparing atrial fibrillation (AF) ablation and antiarrhythmic drugs to our best knowledge have evaluated the efficacy of these treatments in terms of atrial fibrillation (AF) recurrences (with an AF episode of 30 seconds duration as standard primary endpoint) we wanted to use quality of Life (QoL) - general health - as primary endpoint, since the indication for treatment is improving QoL. This was important since, despite the fact that the indication for treatment is to improve (QoL) and reduce symptom, all prior trials have used 30 seconds AF episodes as standard primary endpoint, which if occurred it would be defined as a failed treatment. We also wanted to assess effects on various clinical outcome events. We know from registries such as ORBIT AF registry that around 60 % of AF patients have symptoms resulting in repeated hospitalisation visits in at least 30-40% of patients annually, and that only around 5 % of the AF population are being referred for AF ablation. Previous trials have used intermittent 24 hours Holter recordings whioch does not give the true AF burden (% of time in AF). We therefore also wanted to assess and compare treatments effects on true AF burden by implanting an implantable cardiac monitor (ICM) which continuosly records the heart rhythm. We would then be able to prove that improvement in QoL was directly related to a reduction in AF burden and that treatment differences in QoL was related to a difference in reduction in AF burden. We also wanted to study an AF population in their early AF disease state so that we could offer atrial fibrillation ablation to a broader AF population before their atria have become remodelled and too damaged for a pulmonary vein isolation to be effective.  (more…)
Anesthesiology, Author Interviews, Dermatology, JAMA, NYU, Pediatrics / 14.03.2019

MedicalResearch.com Interview with: Roy G. Geronemus, M.D. Director, Laser & Skin Surgery Center of New York Clinical Professor of Dermatology New York University Medical Center New York, NY 10016 MedicalResearch.com: What is the background for this study? What are the main findings?  Response: We made the observation in clinical practice that port wine stain birthmarks can be safely and effectively treated in early infancy without the need for general anesthesia. This observation is particularly important because of the FDA warnings regarding multiple exposures to general anesthesia under the age of 3 and the potential impact on neurocognitive development as these patients require multiple treatments.

MedicalResearch.com Interview with: Alexander A. Leung, MD, MPH Department of Community Health Sciences Department of Medicine University of Calgary Calgary, Alberta, Canada MedicalResearch.com: What is the background for this study? Response: The 2017 American College of Cardiology and American Heart Association (ACC/AHA) blood pressure guidelines redefined hypertension according to a blood pressure cutoff of ≥130/80 mm Hg, compared to the traditional cutoff of ≥140/90 mm Hg.

Asthma, Author Interviews, JAMA, OBGYNE, Pediatrics, Vitamin D / 12.03.2019

MedicalResearch.com Interview with: Bo Chawes, MD, PhD, DMSc Associate Professor C‌openhagen Prospective Studies on Asthma in Childhood H‌erlev and G‌entofte H‌ospital U‌niversity of C‌openhagen MedicalResearch.com: What is the background for this study? What are the main findings? Response: There has been a global surge in vitamin D deficiency happening in parallel with an increase in prevalence of childhood asthma, which suggests that low maternal vitamin D levels during pregnancy may increase asthma risk in the child. Due to that we conducted a randomized double-blinded controlled trial within the Danish COPSAC2010 cohort (www.copsac.com) of 7-fold (2,800 IU/d) vs. standard dose (400 IU/d) of vitamin D supplementation from pregnancy week 24 aiming to reduce offspring asthma risk. At age 3, we observed a non-significant 24% reduced risk of recurrent asthma-like symptoms, ie. recurrent wheeze, in the high-dose vitamin D group. In the current study, we followed 545 of the 581 children in the study till age 6, where an asthma diagnosis can be established and observed no effect of the high-dose vitamin D supplement on the child's risk of asthma.  (more…)
Alcohol, Author Interviews, JAMA, Weight Research / 12.03.2019

MedicalResearch.com Interview with: Alice R Carter MSc Doctor of Philosophy Student MRC Integrative Epidemiology Unit Population Health Science, Bristol Medical School University of Bristol MedicalResearch.com: What is the background for this study?   Response: Higher body mass index and alcohol intake have been shown to increase the risk of liver disease. Some studies have looked at their combined effect by comparing the risk of liver disease between individuals with both high BMI and high alcohol intake and individuals with low BMI and low alcohol intake. However, these studies have produced mixed results. Some possible reasons for that are errors in self-reported BMI and alcohol intake, other factors confounding the association of BMI & alcohol intake with liver disease risk and changes in lifestyle that individuals with ill health may have been advised to adopt. One way to overcome these limitations is to use a technique called Mendelian randomisation. This method uses genetic differences between individuals that influence their characteristics (e.g. their body mass and how much alcohol they drink) to help understand whether these characteristics are causally related to diseases. Our study used this method to explore the joint effects of BMI and alcohol consumption on liver disease and biomarkers of liver injury.  (more…)
Author Interviews, Brigham & Women's - Harvard, Critical Care - Intensive Care - ICUs, Infections, JAMA / 12.03.2019

MedicalResearch.com Interview with: Chanu Rhee, MD,MPH Assistant Professor of Population Medicine Harvard Medical School / Harvard Pilgrim Health Care Institute Assistant Hospital Epidemiologist Brigham and Women’s Hospital  MedicalResearch.com: What is the background for this study? Response: Sepsis is the body’s reaction to a serious infection that results a cascade of inflammation in the body and organ dysfunction, such as low blood pressure, confusion, or failure of the lungs, kidneys, or liver.   Sepsis is a major cause of death, disability, and cost in the U.S. and around the world.  Growing recognition of this problem has led to numerous sepsis performance improvement initiatives in hospitals around the country.  Some of these efforts have also been catalyzed by high-profile tragic cases of missed sepsis leading to death, which may have contributed to a perception that most sepsis deaths are preventable if doctors and hospitals were only better at recognizing it. However, the extent to which sepsis-related deaths might be preventable with better hospital-based care is unknown.  In my own experience as a critical care physician, a lot of sepsis patients we treat are extremely sick and even when they receive timely and optimal medical care, many do not survive.  This led myself and my colleagues to conduct this study to better understand what types of patients are dying from sepsis and how preventable these deaths might be.  (more…)
Author Interviews, FDA, JAMA / 06.03.2019

MedicalResearch.com Interview with: Craig Alexander Garmendia, PhD Office of Bioresearch Monitoring Operations Office of Regulatory Affairs US Food and Drug Administration Miami, Florida MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Clinical trials under the U.S. Food and Drug Administration’s (FDA) purview have been shown to suffer from falsified data. While the FDA warns researchers when falsified data are discovered, these data still make their way into medical literature. In this novel study, Dr. Garmendia and colleagues conducted a systematic review to examine the effects of publications containing falsified data on meta-analyses using sensitivity analyses. Almost half of all meta-analyses had conclusions altered by publications containing falsified data, while nearly one-third of all analyses had considerable changes in outcomes. (more…)
Author Interviews, Diabetes, Exercise - Fitness, JAMA, Lifestyle & Health, Weight Research / 05.03.2019

MedicalResearch.com Interview with: Giuseppe Pugliese, MD, PhD for the Italian Diabetes and Exercise Study 2 (IDES_2) Investigators Department of Clinical and Molecular Medicine ‘‘La Sapienza’’ University Diabetes Unit, Sant’Andrea University Hospital Rome, Italy MedicalResearch.com: What is the background for this study? Response: There is a growing epidemic of obesity and type 2 diabetes worldwide, which are causally related to the increasing prevalence of “physical inactivity”, i.e., an insufficient amount of moderate-to-vigorous physical activity according to current guidelines, and “sedentariness”, i.e., too many hours, especially if uninterrupted, spent in a sitting or reclined position.  These two unhealthy behaviors exert their detrimental effects independently of each other and are very common among people suffering from type 2 diabetes, who would therefore benefit from increasing physical activity and reducing sedentary time, as recommended by current guidelines. However, such a behavior change is generally difficult for a number of internal and external barriers and requires behavioral interventions targeting both physical activity and sedentary habits.  Unfortunately, there is no definitive evidence that this is indeed feasible and, particularly, that, if adopted, change in behavior can be maintained in the long term.  (more…)
Author Interviews, Clots - Coagulation, Heart Disease, JAMA / 05.03.2019

MedicalResearch.com Interview with: Geoffrey Barnes, MD, MSc Assistant Professor Vascular and Cardiovascular Medicine University of Michigan MedicalResearch.com: What is the background for this study? What are the main findings? Response: Both aspirin and warfarin are commonly used medications meant to prevent thrombotic complications, but might increase rates of bleeding complications. We used a multi-center anticoagulation collaborative to explore how often patients being treated with warfarin were also taking aspirin but without a clear indication. We found that more than one-third (37.5%) of warfarin-treated patients without a clear reason for aspirin therapy were receiving aspirin. And these patients on both warfarin and aspirin experienced higher rates of bleeding and emergency department visits for bleeding than the patients taking warfarin alone. There were no differences in the rate of thrombotic events between the patients taking warfarin alone or those taking warfarin plus aspirin.  (more…)
Author Interviews, Dermatology, Heart Disease, JAMA, Race/Ethnic Diversity / 04.03.2019

MedicalResearch.com Interview with: Francis Alenghat, MD, PhD Assistant Professor of Medicine Section of Cardiology University of Chicago MedicalResearch.com: What is the background for this study? What are the main findings? Response: Psoriasis has been associated with higher rates of atherosclerotic cardiovascular disease (ASCVD), potentially due to higher-than-normal levels of systemic inflammation. Whether this association varies by race was unknown. Also, it was unclear whether patients with psoriasis have more frequent ASCVD because of higher rates of traditional cardiovascular risk factors (smoking, diabetes, hypertension, hyperlipidemia) or because of components intrinsic to psoriasis itself. We found that, amongst a large population of patients with psoriasis, patients of both sexes and most ages had elevated ASCVD rates compared to those without psoriasis. Overall, African American patients with psoriasis had a 15% ASCVD prevalence, whereas it was 10% in white patients with psoriasis. Increased ASCVD associated with psoriasis occurred at earlier ages in African American patients compared to white patients. Traditional cardiovascular risk factors were common in patients with psoriasis and appeared to play a large role in the driving the higher rates of ASCVD in these patients, but even in patients with psoriasis but without any documented traditional risk factors, ASCVD rates were elevated compared to patients without psoriasis.  (more…)
Author Interviews, Brigham & Women's - Harvard, Health Care Systems, JAMA, Mental Health Research / 04.03.2019

MedicalResearch.com Interview with: Mark S. Bauer, M.D. Professor of Psychiatry, Emeritus Harvard Medical School Center for Healthcare Organization and Implementation Research VA Boston Healthcare System-152M Boston, MA 02130 MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Collaborative Chronic Care Models (CCMs) have extensive evidence for their effectiveness in a wide variety of mental health conditions.  CCMs are frameworks of care that include several or all of the following six elements:  work role redesign for anticipatory, continuous care; self-management support for individuals in treatment; provider decision support; information system support for population-based and measurement-guided care; linkage to community resources; and organization and leadership support. However, evidence for Collaborative Chronic Care Model effectiveness comes almost exclusively from highly structured clinical trials.  Little is known about whether CCMs can be implemented in general clinical practice settings, and the implementation evidence that does exist derives primarily from studies of the CCM used in primary care settings to treat depression. We conducted a randomized, stepped wedge implementation trial using implementation facilitation to establish CCMs in general mental health teams in nine US Department of Veterans Affairs medical centers. We found that establishing Collaborative Chronic Care Models was associated with reduced mental health hospitalization rates and, for individuals with complex clinical presentations, improvements in mental health status.  Additionally, standardized assessment of team clinicians indicated that facilitation improved clinician role clarity and increased focus on team goals.

MedicalResearch.com Interview with: Sarah Parish, MSc, DPhil Professor of Medical Statistics and Epidemiology MRC Population Health Research Unit Nuffield Department of Population Health University of Oxford MedicalResearch.com: What is the background for this study? Response: Acquiring reliable randomized evidence of the effects of cardiovascular interventions on cognitive decline is a priority. In this secondary analysis of 3 randomized intervention trials of cardiovascular event prevention, including 45 029 participants undergoing cognitive testing, we estimated the association of the avoidance of vascular events with differences in cognitive function in order to understand whether reports of non-significant results exclude worthwhile benefit.  (more…)
Alzheimer's - Dementia, Author Interviews, JAMA, Pharmacology, University of Pittsburgh / 01.03.2019

MedicalResearch.com Interview with: Alvaro San-Juan-Rodriguez, PharmD Pharmacoeconomics, Outcomes and Pharmacoanalytics Research Fellow Pharmacy and Therapeutics School of Pharmacy University of Pittsburgh MedicalResearch.com: What are the main findings? Response: Currently, there are 4 antidementia drugs approved by the FDA for the treatment of Alzheimer’s disease, including 3 acetylcholinesterase inhibitors (AChEIs)—donepezil, rivastigmine, and galantamine—and the N-methyl-D-aspartic receptor antagonist memantine. On the one hand, evidence about the effect of these drugs at delaying nursing home admission is still sparse and conflicting. On the other, all these antidementia medications have been associated with several cardiovascular side effects, such as bradycardia, ventricular tachycardia, syncope, QT interval prolongation, atrioventricular block or even myocardial infarction. In this study, we aimed to compare time to nursing home admission and time to cardiovascular side effects across all drug therapies available for the treatment of Alzheimer’s disease. In doing so, we used 2006-2014 medical and pharmacy claims data from Medicare Part D beneficiaries with a new diagnosis Alzheimer’s disease who initiated antidementia drug therapy. (more…)
Author Interviews, Biomarkers, CT Scanning, JAMA, Lung Cancer, Medical Imaging / 01.03.2019

MedicalResearch.com Interview with: Martin C. Tammemägi PhD Senior Scientist Cancer Care Ontario | Prevention & Cancer Control Scientific Lead Lung Cancer Screening Pilot for People at High Risk Professor (Epidemiology) | Brock University Department of Health Sciences Ontario, Canada MedicalResearch.com: What is the background for this study? Response: Some prediction models can accurately predict lung cancer risk (probability of developing lung cancer during a specified time). Good model predictors include sociodemographic, medical and exposure variables. In recent years, low dose computed tomography (LDCT) lung cancer screening has become widespread in trials, pilots, demonstration studies, and public health practice. It appears that screening results provides added valuable, independent predictive information regarding future lung cancer risk, aside from the lung cancers directly detected from the diagnostic investigations resulting from positive screens.

MedicalResearch.com Interview with: Mr. Tim Badgery-Parker ELS, BSc(Hons), MBiostat Research Fellow,Value in Health Care Division Menzies Centre for Health Policy MedicalResearch.com: What is the background for this study? Response: This is part of a large program of work at the Menzies Centre for Health Policy on low-value care in the Australian health system. We have previously published rates of low-value care in public hospitals in Australia’s most populous state, New South Wales, and a report on rates in the Australian private health insurance population is due for publication shortly. We have also done similar analyses for other Australian state health systems. This particular paper extends the basic measurement work to focus on what we call the ‘cascade’ effects. That is, looking beyond how much low-value care occurs to examine the consequence for patients and the health system of providing these low-value procedures. (more…)
Allergies, Author Interviews, Immunotherapy, JAMA, Pediatrics / 01.03.2019

MedicalResearch.com Interview with: Dr. Matthew Greenhawt Director, Food Challenge and Research Unit Children’s Hospital Colorado MedicalResearch.com: What is the background for this study? Response: In the US, nearly one million children suffer from a peanut allergy and severe reactions to food allergens are not uncommon – yet there is significant unmet need in the food allergy immunotherapy space, as there are no currently approved treatment options. That being said, we are encouraged by the efficacy and safety data, which support Viaskin Peanut as a convenient and well-tolerated potential treatment option for the peanut allergy. In the pivotal Phase III clinical trial (PEPITES) just published in The Journal of the American Medical Association (JAMA), Viaskin Peanut – the first epicutaneous immunotherapy (EPIT) in development that leverages the skin to activate the immune system – provided statistically significant desensitization in peanut-allergic children ages 4-11 years old. Patients who were treated with active therapy were more likely to have increased their eliciting dose to peanut (the amount of peanut protein ingested before an objective allergic reaction was seen during a double-blind, placebo-controlled food challenge) by a required amount as compared to patients treated with a placebo patch. The improvement suggests a reduced risk of allergic reaction to accidental peanut ingestion in the group treated with Viaskin Peanut, with no change seen in the placebo group. (more…)
Author Interviews, JAMA, Mental Health Research, Pharmacology / 01.03.2019

MedicalResearch.com Interview with: Kuan-Pin Su, MD, PhD China Medical University Taichung, Taiwan MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Delirium, also known as acute confusional state, is a serious disturbance in mental abilities that results in confused thinking and reduced awareness of the environment. Delirium can often be traced to one or more contributing factors, such as a severe or chronic illness, changes in metabolic balance (such as low sodium), medication, infection, surgery, or alcohol or drug intoxication or withdrawal. It’s critically important to identify and treat delirium because some of the contributing factors could be life-threatening. However, there is no sufficient evidence for choice of medication to treat or prevent the symptoms of delirium. A recent paper, Association of Delirium Response and Safety of Pharmacological Interventions for the Management and Prevention of Delirium A Network Meta-analysis, published in JAMA Psychiatry provides important findings of this missing piece in that important clinical uncertainty. The leading author, Professor Kuan-Pin Su, at the China Medical University in Taichung, Taiwan, concludes the main finding about treatment/prevention of delirium: “In this report, we found that the combination of haloperidol and lorazepam demonstrated the best option for treatment of delirium, while ramelteon for prevention against delirium.  (more…)
Addiction, Author Interviews, JAMA, Surgical Research / 27.02.2019

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: Nonmedical prescription opioid use and prescription opioid-related overdose remain significant concerns among adolescents and young adults. Among adolescents and young adults prescribed an opioid after surgery, prior work found that 4.8% of opioid-naïve patients develop new persistent use, filling additional opioid prescriptions at 3-6 months after surgery. This work found associations of persistent use with diagnoses such as chronic pain disorders, depression, anxiety, and prior substance use disorder. It is likely that for young patients, family members may also play an important role in development of new persistent use, but this has not previously been explored. We performed this study to evaluate whether long-term opioid use among family members was associated with prescription opioid fills among adolescents and young adults perioperatively – and we found that opioid-naïve adolescents and young adults who have 1 or more family members with long-term opioid use are more likely to fill at the time of surgery, during recovery, and in the long-term with a near-doubling of rates of new persistent use.

Anesthesiology, Author Interviews, JAMA, Surgical Research / 25.02.2019

MedicalResearch.com Interview with: Bheeshma Ravi, MD, PhD, FRCSC Scientist Sunnybrook Health Sciences Centre Holland Centre Toronto, ON MedicalResearch.com: What is the background for this study? What are the main findings? Response: Delirium is an acute change in mental status characterized by fluctuating disturbances of consciousness and attention. Elderly patients are prone to delirium after surgery; this contributes significantly to post-operative morbidity and can also lead to long-term disability. Our study found that among older adults undergoing hip fracture surgery, both an increased duration of surgery and a general anesthetic are associated with an increased risk for post-operative delirium.​  (more…)
Aging, Author Interviews, Exercise - Fitness, JAMA / 25.02.2019

MedicalResearch.com Interview with: Fuzhong Li, Ph.D. Senior Scientist Oregon Research Institute MedicalResearch.com: What is the background for this study? What are the main findings? Response: Injurious falls among community-dwelling older adults are a serious public health and cost-bearing problem worldwide.Exercise has been shown to reduce falls and injurious falls among older adults. However, evidence is limited with regard to the type of exercise interventions that are most effective, without exacerbating the risk in some individuals, in reducing injurious falls. This study addresses this knowledge gap in the field of falls prevention. Findings from this study showed that a six-month Tai Ji Quan program reduced the incidence of injurious falls among frail elderly by 53% compared to a regular (multimodal) exercise intervention. The effect of the Tai Ji Quan intervention was shown to be robust, and still evident at follow-up examinations six months after the study. (more…)
