Author Interviews, JAMA, Surgical Research / 21.10.2016

MedicalResearch.com Interview with: Thue Bisgaard, M.D., D.M.Sc Professor of Surgery, Hvidovre Hospital Hvidovre Denmark MedicalResearch.com: What is the background for this study? What are the main findings? Response: The complete spectrum for the benefits and risks of mesh used to reinforce hernia repair is not known because there are very few clinical trial data reporting hernia outcomes as they pertain to mesh utilization. Generally, there is evidence that mesh is beneficial in terms of less risk of reoperation for recurrence after incisional hernia repair compared with sutured repair. The present study confirmed this for the first time in nationwide analysis with a long-term follow-up of 5 years up. From earlier studies from our group (Ann Surg 2012) it is known that reoperation rate for recurrence severely underestimates overall (clinical) risk of recurrence making differences between mesh vs. sutured repair even much bigger. Although rare (5%) the incidence of mesh-related complications was progressively increasing throughout the study period suggesting that mesh-related complications rate may continue to accrue with even longer follow-up.

Alzheimer's - Dementia, Author Interviews, JAMA, Neurological Disorders / 20.10.2016

MedicalResearch.com Interview with: Dr David Lynch MB, MRCPI Leonard Wolfson Clinical Fellow UCL Institute of Neurology Queen Square, London MedicalResearch.com: What is the background for this study? What are the main findings? Response: In 2011 it was discovered that mutations in a gene called CSF1R cause a rare syndrome of early onset dementia often accompanied by movement disorders, spasticity and seizures, which is named adult onset leukoencephalopathy with axonal spheroids (ALSP). The hallmarks of ALSP are a characteristic appearance on MRI imaging and findings in brain pathological specimens - axonal swellings or 'spheroids'. We manage a multidisciplinary group with expertise in leukoencephalopathies and have previously identified patients with mutations in CSF1R. However, we also found patients with a syndrome typical of ALSP who did not carry mutations in CSF1R. In this study, we showed that some of these patients carry recessive mutations in a different gene, AARS2. This included a patient with characteristic axonal spheroids in brain tissue and typical ALSP clinical and imaging features. (more…)
Author Interviews, Coffee, Heart Disease, JAMA / 17.10.2016

MedicalResearch.com Interview with: Luis E. Rohde, MD, ScD Postgraduate Program in Health Science: Cardiology and Cardiovascular Sciences, Medical School, Federal University of Rio Grande do Sul, Cardiovascular Division, Hospital de Clínicas de Porto Alegre MedicalResearch.com: What is the background for this study? Response: Caffeine-rich beverages have been implicated as a common cause of several cardiac-related symptoms, such as palpitations, tachycardia, or irregular heartbeats. Because of this “intuitive” assumption, counseling to reduce or avoid caffeine consumption is still widely recommended in clinical practice by most physicians for patients with any heart disease.

Author Interviews, JAMA, Outcomes & Safety / 17.10.2016

MedicalResearch.com Interview with: David Michael Levine M.D.,M.A. Division of General Internal Medicine and Primary Care Brigham and Women’s Hospital Boston, Massachusetts MedicalResearch.com: What is the background for this study? What are the main findings? Response: About a decade ago, researchers showed that Americans only received half of recommended health care. Since then, national, regional, and local initiatives have attempted to improve quality and patient experience, but there is incomplete information about whether such efforts have been successful. We found that over the past decade the quality of outpatient care has not consistently improved, while patient experience has improved. (more…)
Alzheimer's - Dementia, Author Interviews, Hormone Therapy, JAMA, Prostate Cancer, University of Pennsylvania / 15.10.2016

MedicalResearch.com Interview with: Kevin T. Nead, MD, MPhil Resident, Radiation Oncology Perelman School of Medicine Hospital of the University of Pennsylvania. MedicalResearch.com: What is the background for this study? Response: Androgen deprivation therapy is a primary treatment for prostate cancer and works by lowering testosterone levels. There is a strong body of research suggesting that low testosterone can negatively impact neurovascular health and function. We were therefore interested in whether androgen deprivation therapy is associated with dementia through an adverse impact on underlying neurovascular function. (more…)
Author Interviews, Genetic Research, JAMA, Schizophrenia / 14.10.2016

MedicalResearch.com Interview with: Panagiotis (Panos) Roussos, MD, PhD Assistant Professor Department of Genetics and Genomic Sciences and Department of Psychiatry Icahn Institute for Genomics and Multiscale Biology Friedman Brain Institute Icahn School of Medicine at Mount Sinai The Leon and Norma Hess Center for Science and Medicine New York, NY 10029 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Schizophrenia is a complex neuropsychiatric illness and multiple genetic risk factors contribute to the disease. However, it is unclear how these genetic risk factors act and which molecular functions are affected in brain cells of patients with schizophrenia. In this study, we used neurons derived from pluripotent stem cells of patients with schizophrenia and control samples with no history of neuropsychiatric disease. We identified changes related to the way DNA transcribes (a.k.a. gene expression) in schizophrenia compared to controls during activation of the neurons. These changes affect genes that have been genetically associated with schizophrenia. Our study provides evidence that multiple genetic risk factors might lead to schizophrenia because of a damaging effect on the activity of neurons. (more…)
Author Interviews, Columbia, JAMA, Mental Health Research, OBGYNE, Pediatrics / 13.10.2016

MedicalResearch.com Interview with: Alan S. Brown, M.D., M.P.H. Professor of Psychiatry and Epidemiology Columbia University Medical Center Director, Program in Birth Cohort Studies, Division of Epidemiology New York State Psychiatric Institute  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Maternal use of antidepressants during pregnancy has been increasing.  A previous study from a team that I led in a national birth cohort in Finland showed that mother’s use of a serotonin reuptake inhibitor antidepressant is related to an increased risk of depression in offspring.  We sought to evaluate whether these medications also increased risk of speech/language, scholastic, and motor outcomes in offspring.  We found an increased risk (37% higher risk) of speech/language disorders in offspring of mothers exposed to SSRIs in pregnancy compared to mothers who were depressed during pregnancy but did not take an SSRI during pregnancy.

Author Interviews, Breast Cancer, Heart Disease, JAMA / 12.10.2016

MedicalResearch.com Interview with: Husam Abdel-Qadir, MD, FRCPC, DABIM (Cardiology and Internal Medicine) Graduate student, Clinical Epidemiology and Health Care Research Elliot Philipson Clinician Scientist Training Program University of Toronto MedicalResearch.com: What is the background for this study? Response: Breast cancer is the most common malignancy among North American women. The successes of screening and treatment have led to a marked increase in the number of breast cancer survivors, whose cardiovascular health is becoming of prime concern. Many recent publications have raised alarm about the incidence of cardiovascular abnormalities after breast cancer treatment. However, there is a paucity of data about the frequency of death from cardiovascular disease rather than breast cancer. Contemporary estimates of the incidence of competing risks like cardiovascular disease are important to guide discussions about prognosis, subsequent follow-up, and survivorship plans. It is important that such incidence estimates are generated using methodology that appropriately accounts for competing risks to avoid providing results that are biased upwards. (more…)
Author Interviews, Cost of Health Care, Dermatology, JAMA, NYU / 12.10.2016

MedicalResearch.com Interview with: Hao Feng, M.D., M.H.S. Resident, Department of Dermatology NYU Langone Medical Center MedicalResearch.com: What is the background for this study? Response: Recently, there has been an increased scrutiny on industry-physician interactions and emphasis on disclosures of interactions. While we know about the types of interaction between dermatologists and industry, we wanted to understand that relationship more in depth by probing the Open Payment database. (more…)
Author Interviews, Brigham & Women's - Harvard, JAMA, Technology / 12.10.2016

MedicalResearch.com Interview with: Ateev Mehrotra, M.D. Associate Professor Department of Health Care Policy Harvard Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prior research has highlighted that physicians make diagnostic errors roughly 10 to 15 percent of the time. Over the last two decades, computer-based checklists and other “fail-safe” digital apps have been increasingly used to reduce medication errors or streamline infection-prevention protocols. Lately, experts have wondered whether computers might also help reduce diagnostic errors. In the study, 234 internal medicine physicians were asked to evaluate 45 clinical cases, involving both common and uncommon conditions with varying degrees of severity. For each case, physicians had to identify the most likely diagnosis along with two additional possible diagnoses. Each clinical vignette was solved by at least 20 physicians. The same cases were also evaluated using 19 symptom checkers, websites or apps that use computers that help patients determine potential diagnoses for what is wrong based on their symptoms. The physicians vastly outperformed the symptom-checker apps, listing the correct diagnosis 72 percent of the time, compared with 34 percent of the time for the digital platforms. Eighty-four percent of clinicians listed the correct diagnosis in the top three possibilities, compared with 51 percent for the digital symptom-checkers. (more…)
Author Interviews, Cancer Research, Cost of Health Care, JAMA, Pharmacology / 12.10.2016

MedicalResearch.com Interview with: Dr. Sham Mailankody, MBBS Memorial Sloan Kettering Cancer Center MedicalResearch.com: What is the background for this study? Response: The high price of older drugs has been increasingly criticized in part because of recent dramatic price hikes. There are some well known examples like pyrimethamine and more recently EpiPen. Whether and to what degree examples like pyrimethamine represent a common problem or exceptional cases remains unknown. Using Medicare data available for Part B, we sought to analyze the change in average sales price of cancer drugs between January 2010 and January 2015, and whether older drugs were more likely to undergo price increases than newer drugs.

Author Interviews, C. difficile, Columbia, Hospital Acquired, JAMA / 12.10.2016

MedicalResearch.com Interview with: Dr. Daniel E. Freedberg MD MS Division of Digestive and Liver Diseases Columbia University Medical Center New York, New York MedicalResearch.com: What is the background for this study? Response: We conducted this study because previous studies indicate that the gastrointestinal microbiome is easily shared between people who co-occupy a given space (such as a hospital room).  We wondered if antibiotics might exert an effect on the local microbial environment. (more…)
Alzheimer's - Dementia, Author Interviews, Critical Care - Intensive Care - ICUs, End of Life Care, Geriatrics, JAMA / 12.10.2016

MedicalResearch.com Interview with: Joan M. Teno, MD, MS Department of Gerontology and Geriatrics, Cambia Palliative Care Center of Excellence University of Washington Medicine Seattle, Washington MedicalResearch.com: What is the background for this study? Response: An important challenge for our health care system is effectively caring for persons that high-need, high-cost — persons afflicted with advanced dementia and severe functional impairment are among these persons, with substantial need and if hospitalized in the ICU and mechanically ventilated are high cost patients, who are unlikely to benefit from this level of care and our best evidence suggest the vast majority of persons would not want this care. In a previous study, we interviewed families of advance dementia with 96% starting the goals of care are to focus comfort. Mechanical ventilation in some cases may be life saving, but in cases such as those with advanced dementia and severe functional impairment, they may result in suffering without an improvement in survival. (more…)
Author Interviews, Infections, JAMA, Pediatrics / 12.10.2016

MedicalResearch.com Interview with: Dr. Soren Gantt MD, PhD, MPH Investigator, BC Children's Hospital Associate Professor, Department of Infectious and Immunological Diseases (Pediatrics) Faculty of Medicine, University of British Columbia MedicalResearch.com: What is the background for this study? What are the main findings? Response: Cytomegalovirus (CMV) is a common virus that is usually transmitted through bodily fluids such as saliva, urine, blood, and breast milk, but it can also cause congenital infection (from a pregnant woman to her fetus). While it doesn’t usually cause problems for most children or adults, congenital CMV often causes serious problems. Congenital CMV causes 25 per cent of all childhood hearing loss and it’s the second most common cause of intellectual disability. Without screening, most infected newborns are not diagnosed in time to treat them with antivirals or provide other care that can make a big difference to improving their life-long outcomes. Our study showed that screening programs for congenital CMV infection are cost-effective. We found that the cost of identifying one case of congenital CMV ranges from US$2000 to US$10,000 through universal screening, or US$566 to $2833 through a targeted screening approach. Our model showed that screening programs resulted in a net savings for the health care system of approximately USD$21 to $32 per newborn for universal screening or USD$11-$27 per newborn for targeted screening by reducing lifetime costs for therapies and lost productivity due to CMV-related health problems. This finding addresses a major barrier to implementing CMV screening programs, as costs have often been viewed as an issue. (more…)
Author Interviews, JAMA, Supplements / 11.10.2016

MedicalResearch.com Interview with: Elizabeth D. Kantor, PhD MPH Department of Epidemiology and Biostatistics Memorial Sloan Kettering Cancer Center NY, NY MedicalResearch.com: What is the background for this study? Response: Prior studies show that use of supplements increased between the 1980s and mid-2000s, and despite much research conducted on the health effects of supplements, we know little about recent trends in use. Given this gap, we decided to create an up-to-date, comprehensive resource on the prevalence and trends of supplement use among US adults using nationally representative data from the National Health and Nutrition Examination Survey (NHANES). Data were collected over seven continuous cycles (from 1999-2000 to 2011-2012). (more…)
Author Interviews, Brigham & Women's - Harvard, Cost of Health Care, JAMA, Outcomes & Safety / 10.10.2016

MedicalResearch.com Interview with: Jared Conley, MD, PhD, MPH Department of Emergency Medicine Massachusetts General Hospital Harvard Medical School Boston, MA 02114 MedicalResearch.com: What is the background for this study? What are the main findings? Response: As the U.S. healthcare system seeks to improve the health of populations and individual patients, there is increasing interest to better align healthcare needs of patients with the most appropriate setting of care—particularly as it relates to hospital-based care (accounting for 1/3 of total U.S. healthcare costs). Avoiding hospitalization—as long as safety and quality are not compromised—is often preferred by patients and the added benefit of potentially making care more affordable further promotes such care redesign efforts. There is a growing body of research studying alternative management strategies to hospitalization; we sought to comprehensively review and analyze this work. Alternative management strategies reviewed include outpatient management, quick diagnostic units, observation units, and hospital-at-home. (more…)
Alzheimer's - Dementia, Author Interviews, Genetic Research, JAMA, Race/Ethnic Diversity / 10.10.2016

MedicalResearch.com Interview with: Dr Tamara Shiner MD PhD Specialist in Neurology Neurology Division Tel Aviv Sourasky Medical Centre MedicalResearch.com: What is the background for this study? What are the main findings? Response: Although in the past believed to be sporadic, there is much emerging evidence for a significant genetic contribution to Dementia with Lewy bodies (DLB). Hetrozygosity for common mutations in the GBA gene have been shown to be more frequent among DLB patients and Parkinson's disease patients than in the general population. We found that GBA mutations are in fact exceptionally frequent among Ashkenazi Jewish (AJ) patients with Dementia with Lewy bodies. Our results indicate that one in three of all Ashkenazi DLB patients carry mutations in this specific gene (compared to approximately 6% in the general Ashkenazi Jewish population). We also found that those who carry these mutations have a more severe disease phenotype. (more…)
Author Interviews, Critical Care - Intensive Care - ICUs, JAMA, Pediatrics / 07.10.2016

MedicalResearch.com Interview with: Dr. Lars W. Andersen MD MPH Department of Emergency Medicine, Beth Israel Deaconess Medical Center Boston, Massachusetts Department of Anesthesiology and Research Center for Emergency Medicine, Aarhus University Hospital, Aarhus, Denmark MedicalResearch.com: What is the background for this study? What are the main findings? Response: Pediatric in-hospital cardiac arrest continues to carry a very high mortality. Thanks to companies such as AEDLeader, professional healthcare staff are able to obtain relevant equipment to help people in need. The health of patients is the priority of any paramedic or doctor. Given the relative rarity of these events at most centers and the acuity and complexity of cardiac arrest, few randomized trials exist. Moreover, few observational studies have addressed the effectiveness of intra-cardiac arrest interventions, including the use of medications and advanced airway management. This is further highlighted in the current American and international guidelines, which provide limited guidance to providers in regards to advanced airway management during pediatric in-hospital cardiac arrest. The primary objective of our study was to establish whether there is an association between tracheal intubation during in-hospital pediatric cardiac arrest and outcomes. As respiratory failure and hypoxia are common prior to cardiac arrest in children, there is a good rational for early advanced airway management in this population. (more…)
Author Interviews, Electronic Records, JAMA, NYU, Technology / 07.10.2016

MedicalResearch.com Interview with: Saul Blecker, MD, MHS Department of Population Health New York University Langone School of Medicine, New York, NY 10016 [email protected] MedicalResearch.com: What is the background for this study? What are the main findings? Response: The identification of conditions or diseases in the electronic health record (EHR) is critical in clinical practice, for quality improvement, and for clinical interventions. Today, a disease such as heart failure is typically identified in real-time using a “problem list”, i.e., a list of conditions for each patient that is maintained by his or her providers, or using simple rules drawn from structured data. In this study, we examined the comparative benefit of using more sophisticated approaches for identifying hospitalized patients with heart failure. (more…)
Author Interviews, Education, JAMA, Mental Health Research, Pediatrics / 06.10.2016

MedicalResearch.com Interview with: Laurie Miller Brotman, PhD Bezos Family Foundation Professor of Early Childhood Development Director, Center for Early Childhood Health and Development Department of Population Health NYU Langone Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: Children attending high-poverty schools are often exposed to an accumulation of stressors and adverse childhood experiences that can interfere with optimal mental health and learning. This study examines mental health and academic outcomes through second grade in nearly 800 Black and Latino children who participated in a randomized controlled trial of ParentCorps--a family-centered, school-based intervention in pre-kindergarten. In the original trial, elementary schools with pre-k programs serving primarily Black and Latino children from low-income families were randomized to receive ParentCorps or standard pre-k programming. ParentCorps includes professional development for pre-k and kindergarten teachers on family engagement, social-emotional learning, and behavioral regulation, and a program for families and pre-k students provided over four months at the school by specially trained pre-k teachers and mental health professionals. ParentCorps creates a space for families to come together, reflect on their cultural values and beliefs, and set goals for their children. Parents learn a set of evidence-based strategies and choose which ones fit for their families—such as helping children solve problems and manage strong feelings, reinforcing positive behavior, setting clear rules and expectations, and providing effective consequences for misbehavior. Teachers and parents help children learn social, emotional and behavioral regulation skills such as identifying feeling sad, mad, or scared, calming bodies during stressful situations, paying attention, and solving problems together. This three year follow-up study finds that ParentCorps as an enhancement to pre-k programming in high-poverty schools results in fewer mental health problems (behavioral and emotional problems) and better academic performance through second grade.

Author Interviews, Bone Density, JAMA, Mental Health Research, Mineral Metabolism, Pediatrics / 06.10.2016

MedicalResearch.com Interview with: Alexis Jamie Feuer MD Assistant Professor of Clinical Pediatrics Weill Cornell Medical College MedicalResearch.com: What is the background for this study? Response: Osteoporosis is a debilitating disorder characterized by low bone density and increased risk of fractures. Adolescence and young adulthood are critically important times for accruing peak bone density and failure to obtain adequate bone mass by early adulthood may result in future osteoporosis. In children, the use of certain medications can lead to a decrement in the acquisition of bone mass. Past studies have shown that stimulant medications, such as those used to treat Attention Deficit Hyperactivity Disorder (ADHD), may slow the rate of linear growth in children. To date, little research has been done to see what effects stimulant use may have on bone density and bone accrual in children. Stimulants exert their effects via activation of the sympathetic nervous system, and as there is mounting evidence that indicates the sympathetic nervous system plays a critical role in the acquisition of bone density, we sought to determine if there is any association between stimulant medication use and bone mass in the pediatric population. (more…)
Author Interviews, JAMA, Karolinski Institute, Mental Health Research / 05.10.2016

MedicalResearch.com Interview with: Gustaf Brander Department of Clinical Neuroscience Karolinska Institutet MedicalResearch.com: What is the background for this study? Response: Obsessive-compulsive disorder (OCD) is believed to be caused by a complex interaction between genetic and environmental factors. Whereas genetic studies are well underway, the research on environmental factors has been lagging behind. As they explain a significant portion of the variance, are potentially malleable, and are essential for understanding how the genetic component works, this area of research is of great importance.

Accidents & Violence, Author Interviews, Clots - Coagulation, JAMA, Surgical Research, Thromboembolism / 03.10.2016

MedicalResearch.com Interview with: Charles A. Karcutskie IV, MD, MA Postdoctoral Research Fellow University of Miami Miller School of Medicine Department of Surgery Divisions of Trauma, Surgical Critical Care, and Burns MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our research group at the Ryder Trauma Center have recently done several studies showing various differences in outcomes and risk based on mechanism of injury. Additionally, venous thromboembolism (VTE) is another topic that our group has focused on in the past several years. Because trauma patients are inherently at a higher risk for VTE due to the nature of their injury, we questioned whether the most important risk factors for VTE were different after blunt or penetrating trauma. At our institution, we assess VTE risk with the Greenfield Risk Assessment Profile, which is a list of several risk factors that each have weight toward an overall risk score. We took these risk factors and analyzed them individually based on mechanism of injury. We found that the factors that contribute to the VTE risk are different based on injury mechanism: After blunt trauma, transfusion status, neurologic status, and pelvic fracture contributed most. After penetrating trauma, vascular injury, severe abdominal injury, and age 40-59 years contributed most. This tells us that mechanism of injury may need to be incorporated into the risk assessment in order to discover the highest risk patients. (more…)
Author Interviews, Diabetes, JAMA / 03.10.2016

MedicalResearch.com Interview with: Dr. Saeid Shahraz Assistant Professor of Medicine Tufts Medical Center MedicalResearch.com: What is the background for this study? Response: American Diabetes Association (ADA) has set up a lower cut point for diagnosing prediabetes ( those with Impaired Fasting  Glucose   100 mg/dL) compared to the World Health Organization's cut point, which is 110 mg/dL. This arbitrariness in cut point definition triples the number of cases labeled as prediabetes. Along with lowering the diagnostic threshold by the ADA, the Centers for Disease Control and Prevention (CDC), the American Medical Association (AMA), and the ADA endorsed and advertised a web-based risk model to define high-risk population for prediabetes. The risk engine asks a few questions ( age, sex, family history of diabetes, history of gestational diabetes and high blood pressure, physical activity and weight) and outputs a score that defines if the person is at risk for prediabetes. We suspected that the risk engine might overestimate the risk. (more…)
Author Interviews, End of Life Care, JAMA / 03.10.2016

MedicalResearch.com Interview with: Joshua R. Lakin, MD Assistant Professor of Medicine Harvard Medical School Dana Farber Cancer Institute MedicalResearch.com: What is the background for this study? What are the main findings? Response: Research has increasingly shown the benefits of early palliative care interventions, especially in those around communication about patient goals and preferences in serious illness. These benefits include improved quality of life and psychological outcomes for patients as well as eased bereavement and decision making for loved ones. We have a large gap to fill in initiating early goals and values conversations with our patients and there are a myriad of systems failures and clinician barriers that do not allow us to do this work in a timely and effective way. Doing so with limited resources, both in specialty palliative care and in the many frontline clinicians doing this work, requires targeting our resources carefully. Doing these conversations earlier means identifying patients upstream, before they are in the last days of life. The Surprise Question – “Would you be surprised if this patient died in the next year?” – has emerged as an attractive option for screening for early palliative care interventions. It has been studied primarily in dialysis and cancer patients and has been demonstrated to have a strong association with risk of death. We set out to test it in a more diverse primary care population. (more…)
Author Interviews, JAMA / 28.09.2016

MedicalResearch.com Interview with: Kanu Okike MD MPH Department of Orthopaedic Surgery, Kaiser Moanalua Medical Center Honolulu, Hawaii MedicalResearch.com: What is the background for this study? What are the main findings? Response: Many journals in the social sciences practice double-blind review, in which reviewers and authors are both blinded to each others' identities. In medicine, on the other hand, most journals practice single-blind review, in which authors' identities are known to reviewers. Concerns have been raised that this could lead to biased reviews, however, especially in the case of well-known authors. In our study, we composed a fabricated test manuscript and randomized reviewers for an orthopaedic journal to receive single-blind (prestigious authors listed) or double-blind (no authors listed) versions. In our study, the reviewers who were under the impression that the manuscript was written by prestigious authors (single-blind review) awarded higher marks and also recommended acceptance more often, in spite of the fact that the manuscripts were otherwise identical.

Author Interviews, JAMA, Stroke / 27.09.2016

MedicalResearch.com Interview with: Dr. Michael Hill, MSc, MD, FRCPC Professor for the Departments of Clinical Neurosciences, Community Health Sciences, Medicine and Radiology University of Calgary Director of the Stroke Unit Calgary Stroke Program Alberta Health Services MedicalResearch.com: What is the background for this study? What are the main findings? Response: The HERMES collaboration is a pooled individual patient meta-analysis of recent endovascular ischemic stroke trials. The current analysis assesses the role of time to treatment and outcome. We show that there is a clear relationship between time from onset-to-treatment and outcome, with treatment gradually becoming less effective as time elapses from stroke onset. Treatment was still effect, on average, out to just beyond 7 hours from stroke onset. (more…)
Author Interviews, JAMA, Pediatrics / 27.09.2016

MedicalResearch.com Interview with: Erik Berg, MD Department of Global Public Health and Primary Care University of Bergen Bergen, Norway MedicalResearch.com: What is the background for this study? What are the main findings? Response: Parents regularly express concern about long term health outcomes for children born with oral cleft. In this study we used population-based long-term follow-up data from multiple national registries to focus on the future health outcomes of cleft cases without additional chronic medical conditions or congenital anomalies. The study cohort consisted of all individuals born in Norway between 1967 and 1992. All patients treated for clefts in Norway during the study period were invited to participate. 2 337 cases with isolated clefts and 1 413 819 unaffected individuals were followed until 2010. The main outcome variables were conditions diagnosed in childhood or early adulthood, need for social security benefits, and risk of death. (more…)
Author Interviews, Baylor College of Medicine Houston, Brain Injury, Depression, JAMA / 26.09.2016

MedicalResearch.com Interview with: Ricardo E. Jorge  MD Professor of Psychiatry and Behavioral Sciences Director Houston Translational Research Center for TBI and Stress Disorders Senior Scientist  Beth K. and Stuart C. Yudofsky Division of Neuropsychiatry Michael E DeBakey VA Medical Center Baylor College of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Depressive disorders affect between one-third and one-half of patients with traumatic brain injury. Once established, these disorders are difficult to treat and frequently follow a chronic and refractory course. Depression has a deleterious effect on TBI outcomes, particularly affecting the community reintegration of TBI patients. In this randomized clinical trial that included 94 adult patients with TBI, the hazards for developing depression for participants receiving placebo were about 4 times the hazards of participants receiving sertraline treatment.
