Author Interviews, Education, JAMA / 04.06.2018

MedicalResearch.com Interview with: Kathleen M. Finn MD, MPhil Christiana Iyasere MD, MBA Division of General Internal Medicine Department of Medicine Massachusetts General Hospital, Boston MedicalResearch.com: What is the background for this study? Response: While the relationship between resident work hours and patient safety has been extensively studied, little research evaluates the role of attending supervision on patient safety. Beginning with the Bell Commission there have been increased calls for enhanced resident supervision due to patient safety concerns. At the same time, with the growth of the hospitalist movement more faculty physicians join daily resident work rounds under the assumption that increased supervision is better for patient safety and resident education. However, we know that supervision is a complex balancing act, so we wanted to study whether these assumptions were true. On the one hand patient safety is important, but on the other adult learning theory argues residents need to be challenged to work beyond their comfort level. Importantly, being pushed beyond your comfort level often requires appropriate space between teacher and learner. To investigate the role of attending supervision on patient safety and resident learning we studied the impact of two levels of physician supervision on an inpatient general medical team. Twenty-two teaching faculty were randomized to either direct supervision of resident teams for patients previously known to the team vs usual care where they did not join rounds but rather discussed the patients later with the team. Faculty participated in both arms of the study, after completing the first arm they then crossed over to the other arm; each faculty member participated in the study for a total of 4 weeks. (more…)
Author Interviews, Blood Pressure - Hypertension, Heart Disease, JAMA / 02.06.2018

MedicalResearch.com Interview with: Jiang He, MD, PhD Joseph S. Copes Chair of Epidemiology, Professor School of Public Health and Tropical Medicine Tulane University MedicalResearch.com: What is the background for this study? What are the main findings?   Response: The 2017 American College of Cardiology and American Heart Association hypertension guideline recommended lower blood pressure cut points for initiating antihypertensive medication and treatment goals than the previous hypertension guideline. We estimated the prevalence of hypertension and the proportion of the US adult population recommended for antihypertensive treatment according to the 2017 hypertension guideline. More importantly, we estimated the risk reductions of cardiovascular disease and all-cause mortality, as well as increases in adverse events, assuming the entire US adult population achieved the 2017 guideline-recommended systolic blood pressure treatment goals of less than 130 mmHg. Our study indicated the prevalence of hypertension was 45.4%, representing 105 million US adults with hypertension, according to the 2017 hypertension guideline. In addition, the proportion of individuals recommended for antihypertensive treatment was 35.9% or 83 million US adults. Based on data from the National Health and Nutrition Examination Survey, antihypertensive clinical trials, and US population-based cohort studies, we estimated 610 thousand cardiovascular disease events and 334 thousand total deaths could be prevented annually in the US population if the 2017 hypertension guideline systolic blood pressure treatment goals were achieved in the entire US population. Compared to full implementation of the previous hypertension guideline, we estimated the 2017 hypertension guideline recommendations would reduce an additional 340 thousand cardiovascular disease events and 156 thousand deaths per year in the US. Implementing the 2017 hypertension guideline was estimated to increase 62 thousand hypotension, 32 thousand syncope, 31 thousand electrolyte abnormality, and 79 thousand acute kidney injury or kidney failure events. These analyses indicated implementing the 2017 hypertension guideline would significantly increase the proportion of US adults recommended for antihypertensive treatment and further reduce cardiovascular disease events and all-cause mortality, but might increase the number of adverse events in the US population.

Author Interviews, Duke, Education, Heart Disease, JAMA / 01.06.2018

MedicalResearch.com Interview with: Pamela S. Douglas, MD, MACC, FASE, FAHA Ursula Geller Professor of Research in Cardiovascular Disease Duke University School of Medicine Durham, NC 27715     MedicalResearch.com: What is the background for this study? What are the main findings? Response: For any profession to succeed, it needs to attract top talent. We surveyed internal medicine residents to find out what they valued most in their professional development, how they perceived cardiology as field and how these two areas are associated with  their choosing a career in cardiology or another specialty. We found that trainees were seeking careers that had stable hours, were family friendly and female friendly, while they perceived cardiology to  have adverse work conditions, interfere with family life and to not be diverse. We were able to predict career choice with 89-97% accuracy from these responses; the predictors are mix of things that attract to cardiology and those that are deterrents. For men, the attractors outnumber the deterrents, for women its just the opposite. (more…)
Author Interviews, Heart Disease, JAMA, Surgical Research / 01.06.2018

MedicalResearch.com Interview with: Harindra C. Wijeysundera MD PhD FRCPC FCCS FAHA Director of Research, Division of Cardiology, Schulich Heart Centre, Sunnybrook Health Sciences Centre Senior Scientist, Sunnybrook Research Institute (SRI) Associate Professor, Dept. of Medicine & Institute of Health Policy, Management and Evaluation, University of Toronto Adjunct Senior Scientist, Institute for Clinical Evaluative Sciences (ICES) Toronto, ON, Canada MedicalResearch.com: What is the background for this study? What are the main findings? Response: One of the most common complications post TAVR is the need for a permanent pacemaker.  It is unclear if the need for a pacemaker is associated with long term adverse outcomes. Using a population level registry of all TAVR procedures in ontario, canada, we found that pacemakers were required in ~15% of cases.  Requiring a pacemaker was associated with worse long term outcomes, including death, readmission to hospital and emergency room visits.  (more…)
Author Interviews, JAMA, Thromboembolism, University of Michigan / 31.05.2018

MedicalResearch.com Interview with: Paul Grant, MD Associate Professor of Medicine Associate Chief Medical Information Officer Director, Perioperative and Consultative Medicine Division of Hospital Medicine Department of Internal Medicine Michigan Medicine University of Michigan MedicalResearch.com: What is the background for this study? What are the main findings? Response: It is well known that hospitalized medical patients are at risk for venous thromboembolism VTE, but the severity of patient risk can vary significantly. National guidelines have consistently stated that low-risk patients should not receive VTE prophylaxis beyond early ambulation. In this retrospective cohort study, we analyzed data from 52 hospitals participating in the Michigan Hospital Medicine Safety consortium. Trained medical record abstractors at each hospital collected data from 44,775 medical patients including VTE risk factors, type of VTE prophylaxis administered, and contraindications to pharmacologic prophylaxis. Individual patient risk of VTE was determined using the Padua risk assessment model. Of the 32,549 low-risk patients, 77.9% received excess venous thromboembolism prophylaxis as either pharmacologic prophylaxis (30.6%), mechanical prophylaxis (20.8%), or both (26.5%). In the 12,226 high-risk patients, VTE prophylaxis was underused in 22% of patients. The rates of inappropriate prophylaxis varied considerably by hospital.  (more…)
Author Interviews, CDC, JAMA, Neurological Disorders, Zika / 31.05.2018

MedicalResearch.com Interview with: Dr. Emilio Dirlikov, PhD Office of Epidemiology and Research, Puerto Rico Department of Health Epidemic Intelligence Service Division of Scientific Education and Professional Development CDC MedicalResearch.com: What is the background for this study? What are the main findings? Response: After reporting local Zika transmission in December 2015, the Puerto Rico Department of Health (PRDH), US Centers for Disease Control and Prevention (CDC), and University of Puerto Rico began identifying cases of Guillain-Barré syndrome (GBS), testing specimens, and conducting follow-up telephone interviews after patients left the hospital. Through these efforts, we were able to characterize acute clinical features and long-term disability of GBS associated with Zika infection by analyzing data from GBS patients with and without evidence of Zika infection. This investigation increases scientific and medical understanding of Guillain-Barré syndrome following Zika infection, provides insight into the disease processes involved in GBS following Zika infection, and adds to growing evidence of a causal association between Zika and GBS.  (more…)
Author Interviews, JAMA / 30.05.2018

MedicalResearch.com Interview with: “Stop smoking!” by Emil_95 is licensed under CC BY 2.0Shahrokh F. Shariat, M.D. Professor and Chairman Department of Urology, Comprehensive Cancer Center Medical University Vienna Adjunct Professor of Urology and Medical Oncology Weill Medical College of Cornell University, New York, NY, USA Adjunct Professor of Urology UT Southwestern, Dallas, TX MedicalResearch.com: What is the background for this study? What are the main findings? Response: We know that tobacco smoking produces more than 70 carcinogens and is associated with worse prognosis in many solid cancers. Although the association between cigarette smoking and prostate cancer death has been demonstrated, such association regarding other end points is still unclear. We evaluated different disease endpoints, such as recurrence, occurrence of metastasis and cancer-specific mortality at an earlier stage of disease. We found that smokers who underwent primary treatment for localized prostate cancer - such as radical prostatectomy and radiotherapy - are at increased risk of recurrence, metastasis and cancer-specific mortality.  (more…)
Author Interviews, Gender Differences, JAMA / 30.05.2018

MedicalResearch.com Interview with: Julia Raifman, ScD SM Assistant Professor Health Law, Policy, and Management Boston University School of Public Health Boston, MA 02118 MedicalResearch.com: What is the background for this study? What methods did you use? What are the main findings? Response: The study was motivated by evidence that lesbian, gay, and bisexual (LGB) people in the United States have elevated levels of depression, anxiety, suicide, and mental distress. LGB mental health disparities have been linked to experiences of stigma based on sexual orientation, but most of this evidence comes from studies of association. We were interested in investigating how state policies permitting the denial of services to same-sex couples affected the mental health of LGB individuals. We used data that are representative of all adults in each of the nine states included in the study, from the 2014 to 2016 waves of the Behavioral Risk Factor Surveillance System (BRFSS). The main outcome was mental distress, which can include stress, depression, and problems with emotions. We evaluated changes in mental distress among LGB adults in three states that passed policies permitting the denial of services to same-sex couples compared to changes in mental distress among heterosexual adults in the same states and among LGB adults in six control states. We controlled for all state characteristics that did not change over time, as well as individual age group, race, ethnicity,  sex, educational attainment, employment, income, and marital status.  (more…)
Author Interviews, Dermatology, JAMA / 30.05.2018

MedicalResearch.com Interview with: Andrew Blauvelt, M.D., M.B.A. President Oregon Medical Research Center  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: This new paper focuses on treatment of psoriasis in classically difficult-to-treat areas of the body, which include the scalp, the palms/soles, and the fingernails. We show that guselkumab, which is a new biologic therapy that selectively targets IL-23 (a key pro-inflammatory cytokine in psoriasis pathogenesis), works well in these areas affected by psoriasis. More specifically, after 6 months of treatment with guselkumab, approximately 85%, 80%, and 60% of patients achieved complete or near complete clearance of psoriasis in their scalp, palms/soles, and fingernails, respectively.  (more…)
Author Interviews, JAMA, Melanoma, UCLA / 24.05.2018

MedicalResearch.com Interview with: Joann G. Elmore, MD, MPH Professor of Medicine David Geffen School of Medicine at UCLA Director of the UCLA National Clinician Scholars Program Affiliate Professor of Medicine, University of Washington School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings?  Response: In a recent study published in 2017 in the British Medical Journal, our team found that pathologists disagreed on their diagnoses of some melanocytic skin biopsy lesions and early stage invasive melanoma more than 50% of the time. This concerning level of disagreement was particularly true for diagnoses in the middle of the disease spectrum, such as atypical lesions and melanoma in situ.  For example, Figure 1 from this paper shows the diagnoses of 36 pathologists who interpreted the same glass slide of a skin biopsy using their own microscopes; the diagnoses ranged from a benign lesion to invasive melanoma. Since that study, the American Joint Committee on Cancer has released new guidelines for melanoma staging. Given this change, we wanted to examine whether the updated guidelines improved the reliability of melanoma diagnosis. We found that using the new guidelines improved the accuracy of pathologists’ diagnoses for invasive melanoma (Elmore J, et al, JAMA Network Open 2018).  (more…)
Author Interviews, Cost of Health Care, End of Life Care, Geriatrics, JAMA, Medicare / 23.05.2018

MedicalResearch.com Interview with: William B Weeks, MD, PhD, MBA The Dartmouth Institute MedicalResearch.com: What is the background for this study? What are the main findings? Response: The background for the study is that a common narrative is that end-of-life healthcare costs are driving overall healthcare cost growth.  Growth in end-of-life care has been shown, in research studies through the mid 2000’s, to be attributable to increasing intensity of care at the end-of-life (i.e., more hospitalizations and more use of ICUs). The main findings of our study are that indeed there have been substantial increases in per-capita end-of-life care costs within the Medicare fee-for-service population between 2004-2009, but those per-capita costs dropped pretty substantially between 2009-2014.  Further, the drop in per-capita costs attributable to Medicare patients who died (and were, therefore, at the end-of-life) accounts for much of the mitigation in cost growth that has been found since 2009 in the overall Medicare fee-for-service population.

Author Interviews, JAMA, NIH / 23.05.2018

MedicalResearch.com Interview with: Jennifer Villani, PhD, MPH Office of Disease Prevention National Institutes of Health MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The US Preventive Services Task Force (USPSTF) develops recommendations for the delivery of clinical preventive services based on the highest quality scientific evidence available. We performed a comprehensive assessment of the sources of funding for the research studies in this evidence base. The results showed that government agencies supported the most articles (56%), with the remaining support coming from nonprofits or universities (32%), and industry (17%). The National Institutes of Health was the single largest funder of research articles underlying the USPSTF recommendations.  (more…)
Author Interviews, Depression, Emory, Heart Disease, JAMA / 22.05.2018

MedicalResearch.com Interview with: Viola Vaccarino, MD, PhD Department of Epidemiology and Division of Cardiology Professor, Department of Medicine Emory University School of Medicine Atlanta, Georgia  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous studies have shown that people with depression tend to have lower heart rate variability (HRV), an index of autonomic nervous system dysregulation derived by monitoring the electrocardiogram over time, usually for 24 hours. Other literature, however, has pointed out that autonomic dysregulation (as indexed by reduced HRV) may also cause depression. Thus, the direction of the association between reduced HRV and depression still remains unclear. In addition, these two characteristics could share common pathophysiology, making shared familial background and genetic factors potential determinants of this association. (more…)
Author Interviews, Global Health, JAMA, Leukemia / 21.05.2018

MedicalResearch.com Interview with: Andrew J. Cowan, MD Seattle Cancer Care Alliance Division of Medical Oncology University of Washington, Seattle MedicalResearch.com: What is the background for this study? What are the main findings?   Response: Multiple myeloma (MM) is a plasma cell neoplasm with substantial morbidity and mortality. A comprehensive description of the global burden of multiple myeloma is needed to help direct health policy, resource allocation, research, and patient care. Myeloma cases and deaths increased from 1990 to 2016, with middle-income countries contributing the most to this increase. Treatment availability is very limited in countries with low socioeconomic development. (more…)
ADHD, Author Interviews, Columbia, JAMA, Toxin Research / 21.05.2018

MedicalResearch.com Interview with: Marianthi-Anna Kioumourtzoglou ScD Assistant Professor Environmental Health Sciences Mailman School of Public Health Columbia University  Marianthi-Anna Kioumourtzoglou ScD Assistant Professor Environmental Health Sciences Mailman School of Public Health Columbia University  MedicalResearch.com: What is the background for this study? Response: The prevalence of neurodevelopmental disorders, like attention deficit/hyperactivity disorder (ADHD) has been increasing. One of the hypothesized risk factors for increased risk for neurodevelopmental disorders is a class of chemicals known as endocrine disrupting chemicals (EDCs). These chemicals are known to interfere with the endocrine system, i.e. the system that uses hormones to control and coordinate metabolism, reproduction and development. Several high production volume chemicals, ubiquitously present in commercial products, are known or suspected endocrine disruptors. Because of their widespread use in consumer products, the population-wide exposure to known and suspected EDCs is very high. Recently, there has been increased attention in the potential effects of EDCs on neurodevelopment that span multiple generations. Animal studies have provided evidence that exposure to EDCs, such as phthalates and bisphenol A (BPA), alter the behavior and social interactions in mice in three to five generations after exposure. However, evidence of such multi-generational impacts of EDC exposure on neurodevelopment in humans is unavailable, likely because of the lack of detailed information on exposures and outcomes across generations. For this study we leveraged information from a nationwide cohort, the Nurses’ Health Study II (NHSII), to investigate the potential link between exposure to diethylstilbestrol (DES) and third generation ADHD, i.e. ADHD among the grandchildren of the women who used DES while pregnant. DES is a very potent endocrine disruptor that was prescribed between 1938 and 1971 to pregnant women thought to prevent pregnancy complications. In the United States, between 5 and 10 million women are estimated to have used DES, although the exact number is not known. DES was banned in 1971, when was linked to vaginal adenocarcinomas (a rare cancer of the reproductive system) in the daughters of the women who had used it during pregnancy. Since then, DES has been also linked to multiple other reproductive outcomes in DES daughters, as well as with some reproductive outcomes in the grandchildren of the women who used it, such as hypospadias and delated menstrual regularization. However, to our knowledge, no study to date has evaluated the association between DES, or any other EDC, and multigenerational neurodevelopment. (more…)

Author Interviews, JAMA, Orthopedics, Pain Research / 21.05.2018

MedicalResearch.com Interview with: “Back Pain” by betterhealthosteopathy is licensed under PDM 3.0Christine Goertz DC, PhD Vice Chancellor for Research and Health Policy Palmer College of Chiropractic MedicalResearch.com: What is the background for this study? Response: Low back pain in the leading cause of physical disability worldwide, with up to 80% of US adults seeking care for this debilitating condition at some point in their lives. Low-back pain is also one of the most common causes of disability in U.S. military personnel. Although a number of studies have previously evaluated chiropractic care for low back pain, the vast majority had small sample sizes and did not study chiropractic as part of a multi-disciplinary approach to care in real world settings, including the military.

Author Interviews, Heart Disease, JAMA, Stroke / 19.05.2018

MedicalResearch.com Interview with: Anna Gundlund, MD, PhD Herlev-Gentofte Hospital, Department of Cardiology Denmark  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Atrial fibrillation increases a person’s risk of ischemic strokes up to 5-fold. Oral anticoagulation therapy lowers this risk effectively (>60%) and is therefore recommended for patients with atrial fibrillation and at least 1-2 other risk factors for stroke. Our study show, that oral anticoagulation therapy is still underused in patients with atrial fibrillation – even after a stroke event. In stroke survivors with atrial fibrillation, oral anticoagulation therapy were associated with better outcomes than no oral anticoagulation therapy.  (more…)
Author Interviews, Cognitive Issues, JAMA, Social Issues / 18.05.2018

MedicalResearch.com Interview with: Dr Dorina Cadar Research Associate in Dementia Psychobiology Group Department of Behavioural Science and Health University College London London MedicalResearch.com: What is the background for this study? Response: Dementia is one of the most feared medical conditions, which represents a significant global challenge to health and social care. Education may serve different roles in the development of dementia: it is a proxy for early life experiences and (parental) socioeconomic status, it is related to future employment prospects, income and wealth, determines occupational exposures and characteristics of adult life (e.g., job complexity, work stress, environmental exposures) and it provides lifelong skills for optimal mental abilities and mastery. However, given that education is typically completed many decades before dementia onset, other individual and area-based components of socioeconomic status, such as wealth, income and area deprivation may provide a more accurate indication of current socioeconomic resources.  Also, at older ages, accumulated wealth represents a more robust measure of socioeconomic resources than income or occupation alone.

Author Interviews, JAMA, Medical Imaging, Prostate Cancer, Technology / 17.05.2018

MedicalResearch.com Interview with: Andrew J. Armstrong, MD ScM FACP Associate Professor of Medicine, Surgery, Pharmacology and Cancer Biology Associate Director for Clinical Research in Genitourinary Oncology Duke Cancer Institute Divisions of Medical Oncology and Urology Duke University MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Men with prostate cancer commonly develop bone metastases and undergo nuclear medicine bone scans. However, these scans are non-quantitative, and disease burden has been challenging to assess over time and to relate to clinical outcomes. We developed a software program and measurement called the automated bone scan index that essentially reads a standard of care nuclear bone scan, provides a quantitative metric, and demonstrate in a phase 3 trial that this aBSI is highly associated with clinical outcomes including survival, time to symptomatic progression, and prostate cancer specific survival. We accomplished this within a prospective phase 3 international trial of men with metastatic hormone resistant prostate cancer who were followed over a long period of time.  All bone scans were read and measured using the aBSI at baseline, and we found that the aBSI was highly prognostic.  This work validates prior smaller phase 2 BSI studies, and demonstrates both the feasibility and clinical utility for incorporating the aBSI into clinical practice to provide this important prognostic information to patients and providers.

Author Interviews, Dermatology, Education, JAMA, Melanoma / 17.05.2018

MedicalResearch.com Interview with: Michael S. Kolodney, MD, PhD Section of Dermatology, Department of Medicine West Virginia University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Melanoma is easily curable if recognized early.   Dermatologists are good at spotting melanomas because they develop an innate sense of how melanomas appear after examining thousands of malignant and benign lesions.  In contrast, most medical students are relatively disadvantaged by their limited dermatology exposure. We felt that too little experience, rather than lack of knowledge of the rules, is the primary barrier to development of pattern-recognition and intuition as a reliable tool for melanoma diagnosis in non-experts.  To remedy this problem, we developed a novel web-based application to mimic the training of a dermatologist by teaching medical students intuitive melanoma diagnosis in a highly condensed period of time. Our application, which we call Skinder, teaches intuitive visual diagnosis of melanoma by quickly presenting the learner with thousands of benign and malignant skin lesions.  The user makes rapid binary decisions, by swiping right for benign or left for malignant, and receives instant feedback on accuracy. With this application, the learner can amass a mental repository of diagnostic experience in a short amount of time. To determine if intuitive visual diagnosis training is superior to a traditional rule-based approach, we compared our web-based application to a rules based approach, the publicly available INFORMED Skin Education Series. Medical students were tested on the ability top differentiate melanomas from benign pigmented lesions before and after training with either Skinder of the Informed Skin Education Series. The pre-test mean for the Skinder group was 75% correct, compared to 74.7% correct for the INFORMED group. The post-test mean for the skinder application group was 86.3% correct, compared to 77.5% correct for the INFORMED group which was highly signifcant. (more…)
Author Interviews, Genetic Research, JAMA, Schizophrenia / 17.05.2018

MedicalResearch.com Interview with: Tobias Kaufmann PhD Norwegian Centre for Mental Disorders Research (NORMENT), KG Jebsen Centre for Psychosis Research, Division of Mental Health and Addiction, Oslo University Hospital & Institute of Clinical Medicine University of Oslo, Oslo, Norway MedicalResearch.com: What is the background for this study? What are the main findings? Response: Over the past years, a lot of work has pointed toward impaired brain networks in schizophrenia. With this work we assessed brain network stability across different loads of a cognitive task using functional magnetic resonance imaging of the brain. Based on our earlier work on adolescents with pre-clinical signs of mental illness who showed decreased stability of networks across different tasks and conditions, we hypothesized that brain networks in adults with schizophrenia show similar properties of decreased stability. Our results confirmed this hypothesis. Stability was reduced in several large-scale brain networks across the sampled age range from early adulthood to the sixties. Further, network stability was associated with polygenic risk for schizophrenia as well as cognitive task performance. (more…)

MedicalResearch.com Interview with: “Acupuncture Needle” by Acid Pix is licensed under CC BY 2.0Caroline Smith, PhD Professor Clinical Research Western Sydney University Research Theme Champion Health and Wellbeing MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Despite technological improvements to IVF the success of IVF treatment remains low. Consequently, new drugs, laboratory techniques and other treatments need to be developed and rigorously tested to explore their effects on producing healthy babies for women undergoing IVF.  In 2002, the first randomised controlled trial of acupuncture administered a specific form of IVF acupuncture at the time of embryo transfer. The results indicated the chance of achieving a pregnancy from acupuncture was twice that to women undergoing IVF treatment alone. From mid 2000s many women have started to use adjunctive treatments such as acupuncture whilst undergoing IVF.  We conducted and reported on a  pilot study in 2006 which produced results suggesting a benefit. It is important that these findings were rigorously examined in a larger trial. Findings are presented from our trial presented in JAMA. Our study of over 800 Australian and New Zealand women undergoing acupuncture treatment during their IVF (in vitro fertilization) cycle has failed to confirm significant difference in live birth rates.

What are the main findings?  Response: Although the health effects of e-cigarettes remains unclear, e-cigarettes have been marketed as an approach for smoking cessation. Previous studies have reported an increase in e-cigarette use in US people since 2010. The current study showed that from 2014 to 2016, there was an increase in ever use of e-cigarettes but decline in current use of e-cigarettes.  (more…)

MedicalResearch.com Interview with: Dr. Cande V. Ananth, PhD, MPH Adjunct professor Department of Health Policy and Management Mailman School of Public Health Columbia University, NY MedicalResearch.com: What is the background for this study? Response: Preterm delivery rates have declined between 2005 and 2014 in the US and in several European countries. Since reductions in preterm and early term deliveries, and perinatal mortality remain a global health priority, determining the relationship between gestational age distribution and perinatal mortality, remains a challenge. Efforts expended to a more complete understanding of the impact of new interventions, policies, and practices on reducing the burden of early deliveries, and in turn improvements in perinatal survival will be of tremendous benefit for clinical management and care of women during their pregnancy and the newborn.

MedicalResearch.com Interview with: Craig M. Hales, MD, MPH, MS CDR, U.S. Public Health Service Division of Health and Nutrition Examination Surveys National Center for Health Statistics Centers for Disease Control and Prevention MedicalResearch.com: What is the background for this study? Response: Monitoring trends in prescription medication use among children and adolescents is an important part of understanding the health of youth in the U.S. and the healthcare they receive. For this study we used data from the National Health and Nutrition Examination Survey or NHANES, which is a nationally representative survey of the US population and as part of this face-to-face survey in the home, we ask participants about their prescription medication use in the last 30 days and collect information about the prescription directly from the medication package.

Author Interviews, Cancer Research, JAMA, Yale / 15.05.2018

MedicalResearch.com Interview with: Jeremy O'Connor, MD Section of General Internal Medicine Department of Internal Medicine Postdoctoral Fellow, National Clinician Scholars Program Yale University MedicalResearch.com: What is the background for this study?   Response: There has been a lot of enthusiasm for the use of novel therapies in cancer care, and in particular for novel anticancer agents known as immune checkpoint inhibitors. But very little is known about how quickly providers have adopted immune checkpoint inhibitors into clinical practice. Existing studies suggest, in fact, that the process of clinical adoption is slow, with conventional wisdom holding that it takes an average of 17 years for new evidence to change practice. Our study evaluated whether the adoption of novel therapies might be much faster in certain contexts with the early use of immune checkpoint inhibitors as a notable example. (more…)

MedicalResearch.com Interview with: Michael Hawkes MD PhD Adjunct Professor Assistant Professor Pediatrics, Faculty of Medicine School of Public Health University of Alberta MedicalResearch.com: What is the background for this study? What are the main findings?
  • Pneumonia is the leading cause of mortality in children globally.
  • Oxygen is an essential therapy for children with hypoxemic pneumonia, but is not available in many resource-limited and rural areas.
  • Our innovation, solar powered oxygen delivery, harnesses freely available sun and air to delivery oxygen to patients independent of grid electricity.
  • We performed a randomized controlled trial of solar powered oxygen delivery, compared to standard oxygen delivery using compressed oxygen cylinders in children with hypoxemia hospitalized at two centres in Uganda.
  • Solar powered oxygen was non-inferior to cylinder oxygen with respect to clinical outcomes, and offers advantages in terms of reliability, simplicity, and cost.
