Author Interviews, ENT, JAMA, Stanford, Surgical Research / 12.10.2017

MedicalResearch.com Interview with: David Schoppy, MD PhD Resident, Division of Head and Neck Surgery Department of Otolaryngology Stanford University School of Medicine Stanford, Palo Alto, California MedicalResearch.com: What is the background for this study? What are the main findings? Response: There is a growing focus in healthcare on quality, and one component of this focus is the development of robust measures of quality. Currently, there are relatively few validated metrics of performance in oncologic surgery, and several of these indicators are relatively static metrics (such as hospital case volume and institution type). This study examined the relationship between overall survival (one surrogate of quality cancer surgery) and two modifiable variables in Head and Neck surgery - achieving negative surgical margins around a primary tumor and 18 or more lymph nodes from a concurrent neck dissection. After controlling for multiple other patient variables, data collected from the National Cancer Database (NCDB) showed that treatment at hospitals where a high percentage of patients had a surgery with negative margins and 18 or more lymph nodes removed from their neck was associated with improved survival. Importantly, this survival benefit was independent of the individual, patient-level survival benefit conferred by having either of these surgical process measures reached. This study therefore highlights two modifiable measures of institutional performance in Head and Neck surgery that may serve as targets for quality improvement programs. (more…)
Author Interviews, Cost of Health Care, JAMA, PTSD / 06.10.2017

MedicalResearch.com Interview with: Gregory H. Cohen, MPhil, MSW Statistical Analyst Department of Epidemiology School of Public Health Boston University  MedicalResearch.com: What is the background for this study? What are the main findings? Response: We simulated a stepped care case-finding approach to the treatment of posttraumatic stress in New York City, in the aftermath of Hurricane Sandy. Stepped care includes an initial triage screening step which identifies whether a presenting individual is in need of Cognitive Behavioral Therapy, or can be adequately treated at a lower level of care. Our simulation suggests that a stepped care approach to treating symptoms of posttraumatic stress in the aftermath of a hurricane is superior to care as usual in terms of reach and treatment-effectiveness, while being cost-effective.

Author Interviews, Dermatology, JAMA, Melanoma, Surgical Research / 05.10.2017

MedicalResearch.com Interview with: Adewole Adamson, MD, MPP Department of Dermatology UNC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Surgery is the primary intervention for the treatment of melanoma. Little is known about how delays for surgery, defined as the time between diagnosis and surgical treatment, among melanoma patient differ by insurance type. After adjustment of patient-level, provider-level, and tumor-level factors we found that Medicaid patients experience a 36% increased risk of delays in surgery for melanoma. These delays were 19% less likely in patients diagnosed and 18% less likely in patients surgically treated by dermatologists. Non-white patients also had a 38% increased risk of delays. (more…)
Author Interviews, Clots - Coagulation, Genetic Research, JAMA, Surgical Research / 04.10.2017

MedicalResearch.com Interview with: Anne R. Bass, MD Associate Professor of Clinical Medicine Weill Cornell Medical College Rheumatology Fellowship Program Director Hospital for Special Surgery New York, NY 10021 MedicalResearch.com: What is the background for this study? Response: Blood thinners are used after orthopedic surgery to prevent blood clots from forming in the legs and traveling to the lungs. They are also used in patients with certain heart diseases to prevent strokes. Blood thinners, like warfarin, are effective but can be associated with serious bleeding complications, especially if the wrong dose is given. Genetic testing can help doctors predict the right warfarin dose to use in an individual patient. In this trial, ≈1600 elderly patients undergoing hip or knee replacement were randomly assigned to receive warfarin dosing based on genetics plus clinical factors (like height, weight and gender), or based on clinical factors alone. The specific genes tested wereVKORC1, CYP2C9, and CYP4F2 which influence warfarin metabolism and the body’s ability to produce clotting factors. (more…)
Author Interviews, Gastrointestinal Disease, JAMA, Surgical Research / 04.10.2017

MedicalResearch.com Interview with: Marc D. Basson, MD, PhD, MBA Professor of Surgery, Pathology, and Biomedical Science Senior Associate Dean for Medicine and Research University of North Dakota School of Medicine & Health Sciences Grand Forks, ND 58202  MedicalResearch.com: What is the background for this study? What are the main findings? Response: I and other surgeons have previously had the experience of caring for patients with appendicitis who had recently undergone colonoscopy, and wondered if there might be a connection.  However, colonoscopy and appendicitis are both common events, and so it would be difficult to tell whether they are linked or just coincidences from scattered occurrences. After obtaining appropriate regulatory approvals, we identified almost 400,000 veterans from the US Department of Veterans Affairs database who had undergone screening colonoscopy and compared their rates of appendectomy and acute appendicitis in the week following colonoscopy to rates of appendectomy and appendicitis over each of the following 51 weeks.  We asked the question in several different ways and verified our results by examining surgical and pathology reports.  Depending on how the question was asked and appendicitis or appendectomy defined, rates of appendectomy and appendicitis were clearly 4-9 times higher in the first week after diagnostic colonoscopy.  This wasn’t true when we asked whether appendectomy was more common after several other procedures that also required sedation and contact with the medical system.

Author Interviews, JAMA, Urology / 03.10.2017

MedicalResearch.com Interview with: Robert Nam, MD, FRCSC Ajmera Family Chair in Urologic Oncology Professor of Surgery University of Toronto Head, Genitourinary Cancer Site Odette Cancer Centre Sunnybrook Health Sciences Centre  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The well known potentially lethal complications of anti-thrombotic medications of cerebral and gastrointestinal bleeding complications are well known.  However, more common bleeding related complications are not well described .  In particular, gross hematuria is a well known complication of these medications but its frequency and severity is unknown.  We sought to characterize this association among a large population-based cohort consisting of over 2.5 million patients from the Province of Ontario, Canada, using hematuria-related complications was endpoints.  These were defined as undergoing invasive urologic procedures, hospital admissions or emergency visits for gross hematuria.

Author Interviews, Brigham & Women's - Harvard, Cost of Health Care, JAMA, OBGYNE / 03.10.2017

MedicalResearch.com Interview with: Andrew L. Beam, PhD Instructor in Biomedical Informatics Department of Biomedical Informatics Harvard Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study is one piece of a larger story regarding the use of 17-alpha-hydroxyprogesterone caproate (17P) to treat recurrent preterm birth. This drug was originally only available in a compounded form, but since receiving an orphan drug designation in 2011, a branded and manufactured form was marketed under the name "Makena". This branded form was then sold for a much higher price than the compounded version, but a study that provided concrete data on pricing and outcomes had not been done. (more…)
Author Interviews, JAMA, Lung Cancer / 03.10.2017

MedicalResearch.com Interview with: Raymond U. Osarogiagbon, MBBS, FACP Translational Lung Cancer Research Multidisciplinary Thoracic Oncology Program Baptist Centers for Cancer Care Memphis, TN  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Most long-term survivors of lung cancer are among the patients who were fortunate enough to be identified early enough to undergo curative-intent surgery. In the US, 60,000 individuals undergo curative-intent surgery for lung cancer every year. This number is likely to increase over the next few years as lung cancer screening becomes more widely adopted. Unfortunately, fewer than 50% of patients who undergo curative-intent surgery actually survive up to 5 years. We show that the quality of surgery, especially the quality of pathologic nodal staging is a powerful driver of survival differences between groups of patients. In general, pathologic nodal staging (important as it is stratifying patients into risk groups so those at high risk can be offered additional treatments to increase the chances of cure while those at truly low risk can be left alone without exposure to cost and side-effects of additional treatments) is very poorly done. We show how the percentage of patients whose pathologic staging met sequentially more stringently-define thoroughness of staging metrics falls off sharply, while the survival sequentially increases.

Author Interviews, Cancer Research, JAMA, Lung Cancer, Radiation Therapy / 02.10.2017

MedicalResearch.com Interview with: Florence K Keane MD Resident, Radiation Oncology Harvard Radiation Oncology Program Boston, Massachusetts MedicalResearch.com: What is the background for this study? Response: Checkpoint inhibitors (CPIs) have recently transformed the management of patients with metastatic lung cancer, demonstrating significant improvements in overall and progression-free survival in both the first-line setting in patients with increased expression of PD-L1 (≥50%) and in patients with previously treated NSCLC who have progressed on chemotherapy. CPIs are also moving into the treatment of patients with localized lung cancer, with the recently published PACIFIC trial demonstrating a significant improvement in progression-free survival in patients with inoperable stage III NSCLC treated with adjuvant durvalumab after definitive chemoradiotherapy. However, CPIs are associated with unique toxicities as compared to cytotoxic chemotherapy, including pulmonary, endocrine, neurologic, gastrointestinal, and dermatologic adverse events, which may be fatal in some cases. The risk of autoimmune pneumonitis with checkpoint inhibitors is estimated to be on the order of 5%. Many patients with lung cancer will require radiotherapy for palliation of symptoms. Thoracic radiotherapy (TRT) is also a risk factor for pneumonitis, with a dose- and volume-dependent impact on risk. However, it is unknown whether treatment with CPIs and TRT is associated with increased risk of toxicity. (more…)
Author Interviews, Dermatology, JAMA, Surgical Research / 28.09.2017

MedicalResearch.com Interview with: P. Daniel Ward, MD, MS, FACS Facial Plastic Surgeon WardMD Form Medical SpaAdjunct Associate Professor, University of Utah School of Medicine Salt Lake City, Utah 84121 MedicalResearch.com: What is the background for this study? What are the main findings? Response: As a facial plastic surgeon with an interest in finding treatments for patients with facial paralysis, we are always looking for ways to improve the care that our patients receive. One of those treatments is to treat the effects of abnormal and asymmetric facial motion with botulinum, which decreases the deformity that results from facial nerve disorders by decreasing muscular hyperactivity. This study was based on the fact that there are three commercially available types of botulinum available for treatment of the face. There have been studies that have compared the different types of botulinum for cosmetic purposes, but there have not been any studies that specifically looked to see if there were any differences between the different types of botulinum when used for treatment of facial nerve disorders. The main finding of the study is that the three different types of botulinum are essentially equivalent with the exception being that one type of botulinum, incobotulinum toxin, was slightly less effective than the other two types of botulinum at the 4-week follow up point. Of note, all three types were equivalent at all other time points. (more…)

Author Interviews, Brigham & Women's - Harvard, Cost of Health Care, JAMA, Nutrition / 27.09.2017

MedicalResearch.com Interview with: Seth A. Berkowitz, MD, MPH Division of General Internal Medicine Diabetes Population Health Unit Harvard Medical School Massachusetts General Hospital, Boston MedicalResearch.com: What is the background for this study? What are the main findings? Response: There is ever growing pressure to contain healthcare costs in the US. Increasingly, attention is turning to programs that address social determinants of health--that is, those factors which affect health but lie outside the realm of clinical medicine. Prior research has highlighted food insecurity as having a clear association with poor health and higher healthcare costs. SNAP is the nation's largest program to combat food insecurity. However, we did not know whether SNAP participation would be associated with any difference in healthcare costs, compared with eligible non-participants. This study found that participating in SNAP was associated with approximately $1400 lower healthcare expenditures per year in low-income adults. (more…)
Author Interviews, Autism, Genetic Research, JAMA / 27.09.2017

MedicalResearch.com Interview with: Sven Sandin, PhD Assistant Professor Department of Psychiatry Icahn School of Medicine at Mount Sinai New York, NY 10029  MedicalResearch.com: What is the background for this study? What are the main findings? Response: In 2014, we estimated the heritability of autism to be approximately 50%. Motivating us then was the lack of studies in autism heritability using population based and the findings from a twin-study in California finding the heritability to be substantially lower than the 80-90% estimated in previous studies. Since then continued efforts working with the questions on heritability and environmental factors for autism we found differences between different methods and different samples. When we went back to our previous data we found the heritability of autism to be higher than previously estimated. We found that our previous result was due to a methodological artifact where the adjustment for differences in follow-up used in that manuscript underestimated the heritability. Using methods used in other heritability studies the heritability is now estimated to 84%. Importantly, as previously concluded, there is no support for any ‘shared environmental factors’ in the etiology of autism, e.g. environmental factors shared between two siblings. (more…)
Anesthesiology, Author Interviews, JAMA, Pediatrics, Pulmonary Disease / 26.09.2017

MedicalResearch.com Interview with: Shabih U. Hasan, MD, DCH, FRCPC Professor and Staff Neonatologist, Alberta Health Services Department of Pediatrics, Cumming School of Medicine University of Calgary MedicalResearch.com: What is the background for this study? Response: Approximately 8% of all infants are born prematurely (preterm birth <37 weeks postmenstrual age). Preterm infants have many challenges including establishment of adequate pulmonary gas exchange. Due to not yet fully developed lungs, preterm infants require respiratory support consisting of respirators and other forms of non-invasive ventilation modalities and supplemental oxygen.  Bronchopulmonary dysplasia (BPD) is the commonest morbidity among very low birth weight infants as 40% of survivors at postmenstrual age <30 weeks develop BPD. This is a serious condition as it can lead to short- and long-term pulmonary complications, increased hospital visits and neurodevelopmental impairment. BPD is defined where preterm infants require respiratory support and/or supplemental oxygen at 36 weeks postmenstrual age. A number of therapeutic and non-therapeutic modalities have been used to prevent BPD including inhaled nitric oxide (iNO).  In 2006, the NO CLD trial demonstrated that iNO prevented BPD (Relative benefit 1.81; CI 1.27-2.59, P = 0.006) if used according to the NO CLD Protocol (Ballard et al., New England Journal of Medicine, 355:343-353, 2006). Our study (NEWNO; Newborns treated with Nitric Oxide) was designed to replicate the NO CLD study. (more…)
Author Interviews, Brigham & Women's - Harvard, Heart Disease, JAMA, Orthopedics / 22.09.2017

MedicalResearch.com Interview with: Avinainder Singh, M.B.B.S. Research Fellow Cardiovascular Medicine Brigham & Women's Hospital Harvard Medical School Boston, MA MedicalResearch.com: What is the background for this study? Response: Amyloidosis due to aberrant folding of proteins. These misfolded proteins can deposit in various parts of the body and lead to organ dysfunction. The two most common types of amyloidosis affecting the heart include transthyretin and light chain amyloidosis. Transthyretin is a protein produced by the liver which supports the transport of thyroxine and retinol. Wild-type transthyretin amyloidosis (ATTRwt, previously known as senile amyloidosis) occurs due to deposition of misfolded fibrils derived from transthyretin and primarily affects elderly men. Once considered a rare disease, it is now reported to be responsible for nearly 13% of heart failure with preserved ejected fraction and increased wall thickness. Rupture of the biceps tendon is a rare occurrence in the general population (<1 per 1000). We noticed a ruptured biceps tendon in several patients with wild-type transthyretin amyloidosis and performed this study to further evaluate this finding in a group of patients with wild-type transthyretin amyloidosis and in a control group of age-matched patients with non-amyloid heart failure.

Author Interviews, Infections, JAMA, OBGYNE, Surgical Research, Weight Research / 20.09.2017

MedicalResearch.com Interview with: Dr. Carri R. Warshak, MD Associate Professor of Obstetrics & Gynecology University of  Cincinnati MedicalResearch.com: What is the background for this study? Response: Cesarean deliveries are the most common major surgical procedure performed in the United States.  A common complication of cesarean section is wound infections that can include infections in the skin and incision site, or infections in the uterus itself after delivery.  These complications can lead to prolonged hospitalization after delivery for antibiotics and even further surgery in severe infections.  Often these wound complications lead to delayed healing, wound opening which can sometimes take several weeks to heal. Studies have demonstrated as many as 12% of women experience a surgical site infection after delivery. Obesity is a strong risk factor for increased surgical site infections.  Increasing maternal weight increases the risk of wound complications, with a two to five fold increase in risk, making surgical site infections and common and concerning complication of cesarean delivery in obese women.

Author Interviews, JAMA, Leukemia, Transplantation / 19.09.2017

MedicalResearch.com Interview with: Huisheng Ai, MD, Director Department of Hematology and Transplantation, Affiliated Hospital of the Academy  of Military Medical Sciences, Beijing, China  MedicalResearch.com: Which of these results did you find most interesting or surprising? Response: First, we must stress that microtransplant dramatically improved the outcome of older patients with AML. As we know, older AML patients often possess unfavorable prognostic factors, organ dysfunction, and slow post-chemotherapy hematopoietic recovery. Therefore, the general treatment outcome is unsatisfactory even though the incidence is increasing by age with low complete remission (CR) rates (34% to 65%) and poor short-term survival (Two years overall survival was about 11% to 25%). This study involved cases from multiple centers of China, USA and Spain, and found that microtransplant could not only significantly improve complete remission rate in older AML patients among all age groups from 60 to 85, but also improve 1-year and 2-year overall survival and disease free survival especially in patients aged 60 to 75. Second, microtransplant completely overcomes the restriction of HLA typing. The donor could be the patient’s haploidentical family member, or unrelated and fully mismatched one. The incidence of graft-versus-host disease (GVHD) was only 1.1%, even if no any GVHD prevention was given. Other treatment related complications and mortality were also decreased. These results are much better than those of traditional chemotherapy, myeloablative and non-myeloablative transplant, which provides a more safe and effective treatment choice. We are looking forward to seeing the revision of NCCN guideline for older AML to make microtransplant benefit more older patients. (more…)
Author Interviews, Endocrinology, JAMA / 19.09.2017

MedicalResearch.com Interview with: Arjola Bano, MD, MSc, DSc Researcher in the Departments of Internal Medicine and Epidemiology, Erasmus Medical Center, Rotterdam the Netherlands MedicalResearch.com: What is the background for this study? What are the main findings? Response: Thyroid function is clinically defined by the measurements of serum thyroid stimulating hormone (TSH) and free thyroxine (FT4) levels. So far, abnormal TSH and FT4 levels as well as variations within the normal range have been linked to an increased risk of cardiovascular disease and death. However, it remains unclear whether there are differences in life span and years of life lived with and without cardiovascular disease, within the reference range of thyroid function. To investigate this, we performed a prospective study among 7785 middle-aged and elderly people with normal thyroid function. Participants were part of the Rotterdam Study, 65 years on average and 52% females. In our statistical analyses, we accounted for sociodemographic and cardiovascular risk factors. Over a median follow-up of 8.1 years, 789 incident cardiovascular deaths and 1357 deaths occurred. Analyses were performed separately among men and women. Our study found differences in life expectancy within the reference range of thyroid function. At the age of 50 years, people with low-normal thyroid function lived up to 3.5 years longer than those with high-normal thyroid function. Also, people with low-normal thyroid function lived a longer life without cardiovascular disease than those with high-normal thyroid function. (more…)
Author Interviews, CDC, JAMA, Opiods / 19.09.2017

MedicalResearch.com Interview with: Dr. Deborah Dowell, MD MPH Senior Medical Advisor Division of Unintentional Injury Prevention Centers for Disease Control and Prevention MedicalResearch.com: What is the background for this study? Response: Increases in U.S. life expectancy at birth have leveled off from an average of 0.20 years gained per year from 1970 to 2000 to 0.15 years gained per year from 2000 to 2014. U.S. life expectancy decreased from 2014 to 2015 and is now lower than in most high-income countries, with this gap projected to increase. Drug poisoning (overdose) death rates more than doubled in the United States from 2000-2015; those involving opioids more than tripled. Increases in poisoning have been reported to have reduced life expectancy for non-Hispanic white Americans from 2000-2014. Specific contributions of drug, opioid, and alcohol poisoning to changes in U.S. life expectancy since 2000 were unknown. (more…)
Author Interviews, Exercise - Fitness, JAMA, Mental Health Research, Pediatrics / 19.09.2017

MedicalResearch.com Interview with: Michael Alosco, PhD NRSA Postdoctoral Fellow Boston University Alzheimer’s Disease & CTE Center Boston University School of Medicine  MedicalResearch.com: What is the background for this study? What are the main findings? Response: TThe goal of this study was to investigate whether playing youth tackle football, particularly before the age of 12, is associated with worse emotional, behavioral, and cognitive difficulties later in life. Participants in this study included 214 former amateur and professional American football players who were part of the LEGEND study at Boston University. Participants had an average age of 51. 43 played high school football, 103 played college football, and there were 68 professional American football players. The former players were divided into two groups: those who began playing tackle football before age 12 and those who began at age 12 or older. Participants received telephone-administered cognitive tests and completed online measures of depression, behavioral regulation, apathy, and executive functioning, such as initiating activity, problem-solving, planning, and organization. Results from former players who started playing tackle football before the age of 12 were compared to those of participants who started playing at age 12 or later. The study showed that participation in tackle football before age 12 increased the odds for having problems with behavioral regulation, apathy and executive functioning by two-fold and increased the odds for clinically elevated depression scores by three-fold. These findings were independent of the total number of years the participants played football or at what level they played, such as high school, college, or professional. Even when a specific age cutoff was not used, younger age of exposure to tackle football corresponded with worse clinical status. (more…)
Accidents & Violence, Author Interviews, JAMA / 19.09.2017

MedicalResearch.com Interview with: Professor Michael Siegel, MD, MPH Department of Community Health Sciences Boston University School of Public Health Boston, MA 02118 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Each year, more than 1,800 people in the U.S. are killed by their intimate partners. Approximately half of these homicides are committed using firearms. While federal law prohibits people subject to domestic violence restraining orders from possessing firearms, there is no requirement that they surrender guns already in their possession. To close this loophole, several states have enacted laws that not only prohibit gun possession by people subject to restraining orders, but which also explicitly require that they relinquish weapons that they already have. If you are unclear as to the laws of your state, then you should contact a local law firm, such as this nyc lawyer, to discuss your current circumstances. In this study, we investigated the impact of state domestic violence-related firearm laws and rates of intimate partner homicide, using data from all 50 states over a 25-year period, 1991-2015.

Author Interviews, JAMA, OBGYNE, Pediatrics, Smoking / 19.09.2017

MedicalResearch.com Interview with: Filippos Filippidis MD MPH PhD Lecturer in Public Health School of Public Health Imperial College London London MedicalResearch.com: What is the background for this study? What are the main findings? Response: Smoking kills millions of people every year. It is well established that increasing tobacco prices is the most effective way to reduce tobacco consumption and hence mitigate the devastating effects of tobacco on health. Taxation on tobacco products is high in the European Union, which makes cigarettes less affordable. However, transnational tobacco companies are known to manipulate prices, ensuring that cheap or ‘budget’ cigarettes are still available. This is particularly important for younger smokers and those of low socioeconomic status who are more sensitive in price increases. Smoking during pregnancy, as well as exposure of pregnant women and babies to cigarette smoke increase infant mortality. There is also evidence that increasing tobacco prices is associated with lower infant mortality. However, researchers typically use average or premium cigarette prices. We analysed 54 million births from 23 European Union countries to see if the differential between average priced and budget cigarettes (i.e. the availability of cigarettes much cheaper than average priced ones) is associated with infant mortality. We found that increasing average cigarette prices by 1 Euro per pack was associated with 0.23 fewer deaths per 1,000 live births in the same year and an additional 0.16 fewer deaths per 1,000 live births in the following year. A 10% increase in the price differential between budget and average priced cigarettes was associated with 0.07 more deaths per 1,000 live births the following year. This means that 3,195 infant deaths could potentially have been avoided in these 23 countries if there was no price difference between cigarette products over the 10-year study period. (more…)
Author Interviews, Critical Care - Intensive Care - ICUs, Heart Disease, JAMA / 15.09.2017

MedicalResearch.com Interview with: Hans Kirkegaard, MD, PhD, DMSci, DEAA, DLS Research Center for Emergency Medicine and Department of Anesthesiology and Intensive Care Medicine Aarhus University Hospital and Aarhus University Aarhus, Denmark  MedicalResearch.com: What is the background for this study? Response: In 2002, two landmark studies demonstrated that mild therapeutic hypothermia (now known as targeted temperature management, TTM) for 12 or 24 hours improves neurological outcome in adult comatose patients suffering from out of hospital cardiac arrest. Accordingly, international guidelines now recommend TTM for at least 24 hours in this patient group. However, there are no studies, only case reports that explore the effect of prolonged cooling. We therefore wanted to set up a trial that could fill out this knowledge gap, we hypothesized that doubling the hypothermia dose to 48 hour would improve neurological outcome without increasing the risk of adverse events considerably.

Author Interviews, Critical Care - Intensive Care - ICUs, Infections, JAMA / 15.09.2017

MedicalResearch.com Interview with: Dr. Chanu Rhee MD, Assistant Professor Therapeutics Research and Infectious Disease Epidemiology Group Department of Population Medicine at Harvard Medical School / Harvard Pilgrim Health Care Institute Critical Care and Infectious Disease Physician Transplant/Oncology Infectious Disease service and Medical Intensive Care Unit at Brigham and Women’s Hospital  MedicalResearch.com: What is the background for this study? Response: Multiple studies suggest that the incidence of sepsis, the syndrome of life-threatening organ dysfunction caused by infection, is increasing over time, while mortality rates are decreasing.  However, reliably measuring sepsis incidence and trends is challenging because clinical diagnoses of sepsis are subjective and insurance claims data, the traditional method of surveillance, can be affected by changing diagnosis and coding practices over time. In this study, my colleagues and I estimated the current U.S. burden of sepsis and trends using clinical data from the electronic health record systems of a large number of diverse hospitals. The findings, published in JAMA, challenge the use of claims data for sepsis surveillance and suggest that clinical surveillance using electronic health record data provides more objective estimates of sepsis incidence and outcomes.

Author Interviews, Brigham & Women's - Harvard, Endocrinology, Hormone Therapy, JAMA, Menopause / 13.09.2017

MedicalResearch.com Interview with: JoAnn E. Manson, MD, DrPH Chief, Division of Preventive Medicine Brigham and Women's Hospital Professor of Medicine and the Michael and Lee Bell Professor of Women's Health Harvard Medical School Boston, Massachusetts  02215  MedicalResearch.com: What is the background for this study? Response: The current report provides new information on total mortality and the rates of death from specific causes (cardiovascular disease, cancer, other major illnesses) over 18 years of follow-up in the Women’s Health Initiative (WHI) randomized trials of hormone therapy (estrogen + progestin and estrogen alone). This is the first WHI report to focus on all-cause and cause-specific mortality. It includes all of the 27,347 women in the 2 hormone therapy trials with >98% follow-up over 18 years, during which time 7,489 deaths occurred. This is more than twice as many deaths as were included in earlier reports. The report also provides detailed information on differences in results by age group (ages 50-59, 60-69, 70-79) at time of study enrollment. (more…)
ADHD, Author Interviews, Autism, JAMA, NYU / 12.09.2017

MedicalResearch.com Interview with: Dr. Adriana Di Martino, MD Associate Professor, Department of Child and Adolescent Psychiatry NYU Langone Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: While there has been an increased awareness of the co-occurrence of symptoms of Attention Deficit/Hyperactivity Disorder (ADHD) in children with a primary diagnosis of ASD, only recently has there been an appreciation that a substantial proportion of children with ADHD may also have ASD traits. These symptom domains overlap pose a challenge for accurate recognition and targeted treatments, yet their underlying mechanisms have been unknown. With more traditional diagnostic group comparisons we detected a significant influence of ASD on white matter organization, but our analyses of the severity of symptoms across individuals revealed an association between autistic traits and white matter organization, regardless of the individual's diagnosis. These findings were mostly centered around the corpus callosum, a structure that enables communication between the left and right cerebral hemispheres. (more…)
Author Interviews, Cancer Research, Dermatology, JAMA, Surgical Research / 11.09.2017

MedicalResearch.com Interview with: Matthew Q. Miller, MD Department of Otolaryngology–Head and Neck Surgery University of Virginia Health System, Charlottesville  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Skin cancer is the most common type of cancer worldwide. In the United States, 3.3 million people are diagnosed with a new skin cancer annually and many of these individuals will have more than one cancer. The face is the most common place for skin cancers to develop. Mohs micrographic surgery (often referred to as Mohs surgery) is the standard of care for some skin cancers on the face. Once the cancer is removed, the skin defect is usually repaired by the Mohs surgeon but many require referral to a reconstructive surgeon. We were intrigued by a recent publication that noted an increased risk in complications when repair of Mohs defects is delayed beyond 2 days. While most patients that will require referral for reconstruction can be predicted and scheduled accordingly in concert with the Mohs surgery, it is not infrequent that a Mohs procedure requires multiple, unexpected passes to excise the entire cancer and the patient is then left with an unexpectedly large defect requiring reconstruction. These large defects often require more OR time and planning and, therefore, reconstruction cannot be easily completed within 2 days of the Mohs procedure. (more…)

MedicalResearch.com Interview with: Kaveri Korgavkar, MD Department of Dermatology Brown University Providence, Rhode Island  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Photodamage refers to premature skin aging from long-term UV exposure. Topical fluorouracil cream, typically used in the treatment of actinic keratosis, has been suggested for use in treating photodamage due to clinical and histological findings. However, in our ad hoc secondary analysis of a large randomized clinical trial, a standard course of topical fluorouracil did not result in detectable improvement of photodamage. (more…)
