Author Interviews, Gender Differences, Lifestyle & Health / 15.11.2018

MedicalResearch.com Interview with: "Blood pressure check" by Army Medicine is licensed under CC BY 2.0Pallavi Bhandarkar MPH Nova Southeastern University Kirkland, Washington preetipshenoy@gmail.com  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Gender based preventative health has been of interest to medical community since 1900’s with health disparities between males and females being of particular interest. United States founded National Research Institutes for female health in 1900. This led to comprehensive and systematic medical services being offered which have improved female health care significantly. Similar research programs and initiatives to improve men’s health were started only in 2000 (1). Cultural depiction of men being fearless and based on perception of masculinity leads them to underutilize the preventative health care screenings available to them or sometimes even delay care when they need it the most. Males have been found to have higher mortality rates compared to females. Life expectancy for females was 5.0 years higher than for males. The difference in life expectancy between the sexes has narrowed since 1979, when it was 7.8 years, but it increased 0.2 year in 2016 from 2015, the first increase since 1990. Death rates for males increased significantly for age groups 15–24, 25–34, 35–44, and 55–64. Rates decreased significantly for age groups 75–84 and 85 and over” (2) My research study adopted the basic survey design and conducted an anonymous survey throughout United States with men aged 18 to 40 being the participants. Our goal was to identify these gaps, analyze the reasons for underutilization and identify opportunities to improve preventative care guidelines among the male population. The main findings were almost similar to the BFRSS data obtained by CDC in the year 2016. (more…)
Author Interviews, Menopause, Sleep Disorders / 15.11.2018

MedicalResearch.com Interview with: Sooyeon Suh, PhD Department of Psychology Sungshin University Seoul, Republic of Korea MedicalResearch.com: What is the background for this study? What are the main findings? Response: Women who are going through menopause frequently complain of sleep complaints and depressive symptoms in addition to other typical symptoms such as hot flashes and night sweats. Two of the most common ways of becoming menopausal are through natural menopause and surgical menopause. While natural menopause is usually experienced in the course of aging, surgical menopause is usually induced by OBGYN surgery such as bilateral oopherectomy, often as a result of illnesses such as ovarian cancer. Many studies have found that women who experience surgical menopause often experience more psychological and physical difficulties compared to women who transition through menopause naturally due to a more acute drop in estrogen following surgery, it sometimes leads to the need for practices like Advanced Gynecology to help manage the symptoms. Unfortunately, in clinical settings, women who undergo surgical menopause are not provided with additional psychoeducation or customized treatment to address these issues. The main findings of these studies support these issues. In 526 postmenopausal women, women who went through surgical menopause reported significantly worse sleep quality an shorter sleep duration. Additionally, they had a 2.13 times higher likelihood of having insomnia that warranted treatment. Finally, even though women who went through surgical menopause engaged in the same sleep-interfering behaviors (e.g., drinking caffeine, drinking alcohol before bed, watching TV in bed, etc) as women who went through menopause naturally, their sleep was impacted more negatively.

Author Interviews, Environmental Risks, NIH, Nutrition, OBGYNE, Pediatrics / 14.11.2018

MedicalResearch.com Interview with: "Baby Bottle" by brokinhrt2 is licensed under CC BY 2.0Kristen Upson, PhD, MPH and Donna D. Baird, PhD Epidemiology Branch National Institute of Environmental Health Sciences Research Triangle Park, NC 27709  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Menstrual pain is the most common menstrual complaint and can substantially affect the quality of women’s lives. A prior study in young adults who participated in feeding studies as infants reported an increased risk of greater menstrual pain severity in adulthood with soy formula feeding. Since that study, evidence from laboratory animal studies support the disruptive effects of a phytoestrogen present in soy formula, genistein, on reproductive system development, including aspects involved in menstrual pain. The laboratory animal studies also demonstrate that the developmental changes with genistein can persist into adulthood. Given these results, we were interested in further evaluating the association between infant soy formula feeding and menstrual pain in a cohort of young women. In our study of women ages 23-35 years old, we observed that soy formula feeding during infancy was associated with several indicators of severe menstrual pain in reproductive-age women. This included a 40% increased risk of ever using hormonal contraception for menstrual pain and 50% increased risk of moderate/severe menstrual discomfort with most periods during early adulthood.  (more…)
Author Interviews, JAMA, Opiods, Pharmacology / 14.11.2018

MedicalResearch.com Interview with: Talia Puzantian,  PharmD, BCPP Associate Professor of Clinical Sciences, School of Pharmacy and Health Sciences Keck Graduate Institute   MedicalResearch.com: What is the background for this study? Response: Naloxone has been used in hospitals and emergency rooms since the early 1970s. Distribution to laypersons began in the mid-1990s with harm reduction programs such as clean needle exchange programs providing it, along with education, to mostly heroin users. In the years between 1996-2014, 152,000 naloxone kits were distributed in this way with more than 26,000 overdoses reversed (https://www.cdc.gov/mmwr/preview/mmwrhtml/mm6423a2.htm). We have data showing that counties in which there was greater naloxone distribution among laypeople, there were lower opioid death rates (Walley AY et al BMJ 2013). However, not all opioid users at risk for overdose will interface with harm reduction programs, particularly prescription opioid users, hence more recent efforts to increase access to laypersons through pharmacists. Naloxone access laws have been enacted in all 50 states but very little has been published about how they’ve been adopted by pharmacists thus far. One small study (264 pharmacies) from Indiana (Meyerson BE et al Drug Alcohol Depend 2018) showed that 58.1% of pharmacies stocked naloxone, only 23.6% provided it without prescription, and that large chain pharmacies were more likely to do so.

Author Interviews, Weight Research / 14.11.2018

MedicalResearch.com Interview with: Dr. Jamy Ard MD Professor of Epidemiology and Prevention Co-director,the Wake Forest Baptist Health Weight Management Center Wake Forest School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Obesity continues to be a growing health challenge, and doctors need as many resources as possible to help their patients achieve success. The OPTIWIN trial shows that a total meal replacement program like OPTIFAST can help with significant and sustained weight loss. The OPTIFAST Program is a medically monitored weight loss program that combines meal replacement with behavioral counseling and personalized support. In the OPTIWIN study, participants were randomized to either the OPTIFAST Program (OP) or a behavioral intervention using a food-based diet (FB). At both 26 and 52 weeks, the OP group lost, on average, twice as much of their initial body weight as the FB group:
  • At 26 weeks: 12.4% (SE 0.6) vs 6.0% (SE 0.6) of body weight lost (OP vs FB, respectively; p<0.001)
  • At 52 weeks: 10.5% (SE 0.6) vs 5.5% (SE 0.6) of body weight lost (OP vs FB, respectively; p<0.001)
Additionally, the proportion of participants who achieved clinically meaningful weight loss (≥5%, ≥10%, and ≥15%) was significantly higher in the OP group. For example:
  • At 26 weeks, 55% of the OP group lost at least 10% of their initial body weight vs 23% of the FB group (p<0.001)
  • At 52 weeks, 44% of the OP group lost at least 10% of their initial body weight vs 22% of the FB group (p<0.001)

MedicalResearch.com Interview with: Cara Tannenbaum, MD, MSc Director | Directrice Canadian Deprescribing NetworkCara Tannenbaum, MD, MSc Director | Directrice Canadian Deprescribing Network MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The D-Prescribe trial was driven by the need to show that seniors can cut down on their medication in a safe and effective manner. Pharmacists intervened in a proactive way to flag patients who were on potentially risky meds such as sleeping pills, NSAIDs and glyburide and to inform them of the risks, using an educational brochure. Pharmacists also communicated with their physician using an evidence-based pharmaceutical opinion to spark conversations about deprescribing. As a result, 43% of patients succeeded in discontinuing at least one medication over the next 6 months.   (more…)
Addiction, Author Interviews, Opiods / 14.11.2018

MedicalResearch.com Interview with: "Drug Addiction" by Joana Faria is licensed under CC BY-NC-ND 4.0Yingxi (Cimo) Chen, MD, MPH, PhD Postdoctoral Fellow Radiation Epidemiology Branch, DCEG, NCI, NIH Rockville MD 20850  MedicalResearch.com: What is the background for this study? Response: Death rates from drug overdose have more than doubled in the US in the 21st century. Similar increases in drug overdose deaths have been reported in other high-income countries but few studies have compared rates across countries.  (more…)
Author Interviews, Immunotherapy, Pancreatic / 14.11.2018

MedicalResearch.com Interview with: Dr James Kuo, MBBS Medical oncologist and Deputy Medical Director Scientia Clinical Research Sydney, Australia MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Immune checkpoint inhibitors (ICI) that have seen success in the treatment of patients with various tumour types have not been as effective in patients with metastatic pancreatic cancer and therefore immune-therapeutic agents of novel mechanism of action, in particular in combination with existing ICI, need to be investigated. This study set out to test the safety and efficacy of pixatimod, a novel immunomodulatory agent, in combination with nivolumab, firstly in the dose escalation cohorts in patients with any solid tumour for the maximal tolerable dose, and then using this dose to further treat an expansion cohort of patients with pancreatic cancer. Altogether 16 patients had received the combination and in 10 patients in whom treatment response was evaluable, 4 patients experienced a clinical benefit and continued treatment in the trial, with 1 patient having a significant partial response now treated for 48 weeks. Interestingly, all these 4 patients had metastatic colorectal cancer. Side effect profile has been consistent with other immunotherapeutic agent combination and in the patients who had clinical benefit, no treatment related side effects were observed.  (more…)
Author Interviews, Biomarkers, Endocrinology, Prostate Cancer / 14.11.2018

MedicalResearch.com Interview with: Vincenza Conteduca, MD, PhD Istituto Scientifico Romagnolo per lo Studio e la Cura dei Tumori (IRST) Srl - IRCCS Meldola , Italy MedicalResearch.com: What is the background for this study? What are the main findings? Response: In our previous publications, we showed that the study of plasma cell-free DNA holds promise for improving treatment choice in metastatic castration-resistant prostate cancer (mCRPC). Specifically, we demonstrated that the detection in plasma of aberrations (copy number alterations and/or point somatic mutations) of androgen receptor (AR), using an easy and robust multiplex droplet digital PCR method, predicted an adverse outcome in mCRPC patients treated with second-generation AR-directed therapies (abiraterone or enzalutamide) in both settings: chemotherapy-naïve and post-docetaxel. This current multi-institution work builds on our previous discoveries. We investigated the association of androgen receptor status and survival in men treated with docetaxel. Moreover, we performed an exploratory analysis in patients treated with docetaxel or AR-directed therapies as first-line therapy. Interestingly, we observed that plasma AR-gained patients do not have a worse outcome compared to AR-normal patients when treated with docetaxel as first-line therapy. This introduces the opportunity to use plasma to select for docetaxel in preference to androgen receptor-directed therapies in AR gained mCRPC patients. (more…)
Alzheimer's - Dementia, Author Interviews, Coffee, Parkinson's / 14.11.2018

MedicalResearch.com Interview with: Donald Weaver, PhD, MD, FRCPC, FCAHS Senior Scientist and Director, Research Institute Krembil Research Institute University Health Network Toronto, Canada MedicalResearch.com: What is the background for this study? What are the main findings? Response: First, we are seeking novel molecules that might have usefulness in the treatment of Alzheimer’s disease (AD). Since Mother Nature is a superb chemist, natural products are an ideal place to start looking for possible therapeutics. There is a long history (penicillin, digitalis …) of drugs identified from natural product sources. Moreover, in earlier work by us, we have shown that other natural products extracted from maple syrup have possible therapeutic efficacy against AD. Therefore, it was logical for us to look at extracts of coffee. We see similarities between maple syrup and coffee. In both of these natural products, the plant derived material (i.e. the coffee bean, or sap from maple syrup) is initially boiled or roasted prior to its use; thus, it is not a direct simple plant product, but one that has been heated (boiled or roasted). We suspect that the heating process “does more chemistry” enabling the generation of new molecules from the plant derived materials. In our study we show that a class of compounds (phenylindanes) from roasted coffee has the ability to inhibit the misfolding of two proteins (beta-amyloid, tau) whose misfolding and aggregation (“clumping”) is implicated in the disease process of AD. Second, as described below, there is already epidemiological evidence that coffee consumption may offer some protective effects against Alzheimer’s disease and Parkinson’s disease (PD), so by looking at the constituents of coffee for chemicals that might block the clumping of beta-amyloid and/or tau, was an attempt to seek a molecular link explaining the epidemiology.

Author Interviews, Surgical Research, Weight Research / 14.11.2018

MedicalResearch.com Interview with: Alison E. Field, ScD Professor and Chair of Epidemiology Brown University School of Public Heath Providence, RI MedicalResearch.com: What is the background for this study?   Response: In the United States, approximately 40% of adults are obese. There are a range of treatment options, but relatively few people are able to lose weight and maintain the loss. The most effective treatment is bariatric surgery, but even among patients who have undergone bariatric surgery, there is a range in weight change patterns after surgery. This suggests that not all people with obesity are similar. There may be different causes and optimal treatment plans that vary by obesity subgroup. Our goal was to identify subgroups and to examine if they differed in terms of weight loss after bariatric surgery. (more…)
Author Interviews, Exercise - Fitness, Frailty, Geriatrics, JAMA / 13.11.2018

MedicalResearch.com Interview with: "COUCHair for physical therapy" by ewa garniec is licensed under CC BY-NC-ND 3.0Mikel Izquierdo PhD Head and Full professor Department of Health Sciences Public University Navarra, Spain  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Acute hospital admissions are a major contributor to disability in the elderly. Despite resolution of the reason for hospitalization, patients (especially those who are frail) are often discharged with a new major disability. This is a problem that providers of health care and policy makers should prioritize given the expectations of further growth of the population segment composed by old people.  Traditional models of acute hospitalization for older adults seldom include a comprehensive approach to prevent hospitalization-associated impairment in functional and cognitive capacity. In contrast, exercise and early rehabilitation protocols applied during acute hospitalization can prevent functional and cognitive decline in older patients and are associated with a reduced length of stay and lower costs. Yet, patients with cognitive impairment or multimorbidity at baseline are commonly excluded from exercise intervention trials and only ‘conservative’ or ‘traditional’ programs (i.e., focusing on light walking while avoiding resistance training) have been typically applied to elders who are acutely hospitalized. Our intervention proved safe and effective to reverse the aforementioned impairment. We therefore propose that an individualized prescription of multicomponent exercise should become an inherent part of the routine management of hospitalized older adults.  (more…)
Author Interviews, Exercise - Fitness, Pain Research / 13.11.2018

MedicalResearch.com Interview with: Ms Lynne Gaskell MSc University of Salford Manchester UK MedicalResearch.com: What is the background for this study? Response: Musculoskeletal Pain as a result of common problems affecting the back, neck, shoulder, knee and multi-site pain is an increasing cause of reduced function and quality of life, and ever increasing demands on healthcare, Prognosis is often poor with many people reporting persistent symptoms after consulting their primary care practitioner. The likelihood of persistent and recurrent clinical symptoms may accentuate the physical, psychological, and social impacts of musculoskeletal pain particularly with the middle aged and elderly populations. Pilates is an exercise approach that has become increasingly popular in recent years and includes over fifty different exercises to improve flexibility, balance, core strength, core stability. It can therefore can be individualised for people with different needs, preferences, musculoskeletal conditions, ages and abilities. Aligning exercise to patient’s functional needs has been linked to long-term exercise adherence. Many physiotherapists such as sydney physio solutions have started to specialise in this as a form of treatment, click here for more info on pilates and the many benefits they can have on your physical health. This study investigated the personal experiences and perceptions of the impact of Pilates on the day-to-day lives of adults with a myriad of chronic MSK conditions following a 12 week Pilates Exercise Programme.The results were organised into five main themes: 1. Physical Improvements strength, core stability, flexibility and balance. 2. Pilates Promotes an Active Lifestyle and improved performance at work and / or hobbies. 3. Psychosocial benefits and improved confidence, 4. Increased Autonomy in Managing their own Musculoskeletal Condition and 5. Motivation to continue with exercise. (more…)
Author Interviews, JAMA, OBGYNE / 13.11.2018

MedicalResearch.com Interview with: Joel Ray MD, MSc, FRCPC Institute of Health Policy, Management and Evaluation Faculty of Medicine University of Toronto, Toronto MedicalResearch.com: What is the background for this study? What are the main findings? Response: Many women who die within childbirth or soon thereafter experience rapid onset of morbidity/illness before succumbing. Thus, severe maternal morbidity (SMM) offers a detectable (or set of detectable) conditions that might be dealt with before they progress to a fatality. Even so, severe maternal morbidity alone can be non-fatal, but create disability for a new mother (e.g., a stroke), or prolong separation of mother and newborn. So, we showed that, as the number of severe maternal morbidity indicators rises, so does the probability of maternal death. This relation was exponential in nature.   (more…)
AHA Journals, Author Interviews, Heart Disease, Surgical Research / 13.11.2018

MedicalResearch.com Interview with: Dr. Srikanth Yandrapalli New York Medical College NYMC · Cardiology MedicalResearch.com: What is the background for this study? What are the main findings? Response: Selection of coronary artery bypass grafting over percutaneous coronary intervention during an acute myocardial infarction is influenced by the extent of coronary artery disease and patient comorbidities. Prior studies have shown sex and racial differences in coronary artery diseaseburden. We sought to identify if there are any sex and racial differences in the utilization of  coronary artery bypass grafting over percutaneous coronary intervention during a revascularized first  acute myocardial infarction in the US. We found that males had a higher coronary artery bypass grafting rate than women, and compared to Whites, Blacks had lower coronary artery bypass grafting rate and Asians had higher coronary artery bypass grafting at the time of a first myocardial infarction.

Annals Internal Medicine, Author Interviews, Blood Clots, Emergency Care, Kaiser Permanente, Pulmonary Disease, UC Davis / 13.11.2018

MedicalResearch.com Interview with: David R. Vinson, MD Department of Emergency Medicine Kaiser Permanente Sacramento Medical Center Sacramento, CA MedicalResearch.com: What is the background for this study? What are the main findings? Response: At least one-third of emergency department (ED) patients with acute blood clots in the lung, or pulmonary embolism (PE), are eligible for expedited discharged to home, either directly from the ED or after a short (<24 hour) period of observation. Yet in in most hospitals in the U.S. and around the world nearly all ED patients with acute PE are hospitalized. These unnecessary hospitalizations are a poor use of health care resources, tie up inpatient beds, and expose patients to the cost, inconvenience, and risk of inpatient care. The better-performing medical centers have two characteristics in common: they help their physicians identify which PE patients are candidates for outpatient care and they facilitate timely post-discharge follow-up. At Kaiser Permanente Northern California (KPNC), we have had the follow-up system in place for some time, but didn’t have a way to help our physicians sort out which patients with acute PE would benefit from home management. To correct this, we designed a secure, web-based clinical decision support system that was integrated with the electronic health record. When activated, it presented to the emergency physician the validated PE Severity Index, which uses patient demographics, vital signs, examination findings, and past medical history to classify patients into different risk strata, correlated with eligibility for home care. To make use of the PE Severity Index easier and more streamlined for the physician, the tool drew in information from the patient’s comprehensive medical records to accurately auto-populate the PE Severity Index. The tool then calculated for the physician the patient’s risk score and estimated 30-day mortality, and also offered a site-of-care recommendation, for example, “outpatient management is often possible.” The tool also reminded the physician of relative contraindications to outpatient management. At the time, only 10 EDs in KPNC had an on-site physician researcher, who for this study served as physician educator, study promotor, and enrollment auditor to provide physician-specific feedback. These 10 EDs functioned as the intervention sites, while the other 11 EDs within KPNC served as concurrent controls. Our primary outcome was the percentage of eligible ED patients with acute PE who had an expedited discharge to home, as defined above. During the 16-month study period (8-month pre-intervention and 8-months post-intervention), we cared for 1,703 eligible ED patients with acute PE. Adjusted home discharge increased at intervention sites from 17% to 28%, a greater than 60% relative increase. There were no changes in home discharge observed at the control sites (about 15% throughout the 16-month study). The increase in home discharge was not associated with an increase in short-term return visits or major complications.  (more…)
Annals Internal Medicine, Author Interviews, Heart Disease, Race/Ethnic Diversity, Stanford / 13.11.2018

MedicalResearch.com Interview with: Katie Hastings MPH Stanford University School of Medicine Stanford, California MedicalResearch.com: What is the background for this study? What are the main findings? Response: Heart disease has been the leading cause of death since the early 1900s, but recent data has suggested cancer will surpass heart disease in the upcoming decades. To date, this is the first study to examine the transition from heart disease to cancer mortality as the leading cause of death by U.S. county and sociodemographic characteristics using national mortality records from 2003 to 2015. Our main findings are:
  • Epidemiologic transition is occurring earlier in high compared to low income U.S. counties, and occurs earlier for Asian Americans, Hispanics, and NHWs compared to blacks and American Indians/Alaska Natives.
  • Data may suggest that this shift arises from larger reductions in heart disease than cancer mortality over the study period, particularly in the highest income counties.
  • Continued disparities in heart disease and cancer mortality between blacks and other racial/ethnic groups, even in the highest income quintiles. While blacks continue to have the highest overall mortality than any other group, we do show this population experienced the greatest overall improvements in mortality (i.e. mortality rate reductions over time) for all-cause, heart disease, and cancer compared to all other racial/ethnic groups (except for heart disease in Hispanics).

Author Interviews, Autism, Biomarkers, Genetic Research / 12.11.2018

MedicalResearch.com Interview with: Steven D. Hicks, M.D.,Ph.D Department of Pediatrics Penn State College of Medicine Hershey, PA MedicalResearch.com: What is the background for this study? What are the main findings? Response: Since autism has both genetic and environmental underpinnings, my colleagues and I suspected that transcriptional elements (e.g. regulatory RNA molecules) might be different in the saliva of children with autism compared to peers without autism. We used a non-biased approach to analyze saliva from 372 children, and allowed machine learning techniques to inform which RNA elements best predicted autism status. To our surprise, microbial RNA levels and human RNA levels were equally powerful in predicting which children had autism. This may be because some children with autism eat restricted diets, resist tooth brushing, or put foreign objects in their mouths. The end result was a panel of 32 RNAs (20 human and 12 bacterial) that identified autism with 87% accuracy. Interestingly, when we tested the panel in a completely separate set of 84 children (including children from a different geographic region) the accuracy remained 88%.  (more…)
Author Interviews, Nutrition, Pediatrics / 12.11.2018

MedicalResearch.com Interview with: Allison Bovell-Ammon, M.Div. Deputy Director of Policy Strategy Children's HealthWatchAllison Bovell-Ammon, M.Div. Deputy Director of Policy Strategy Children's HealthWatch MedicalResearch.com: What is the background for this study?   Response: Children’s HealthWatch was founded in 1998 by pediatric providers treating children with failure to thrive in six US cities across the country. They began their research on the health impacts of economic hardships like food insecurity in response to the 1996 welfare reform legislation after witnessing deteriorating health among young children in their clinics as a result of welfare sanctions on families. Over the years, the scope of the research has expanded to include research on food insecurity, housing instability, energy insecurity, health care hardships, and child care constraints. Through our current network of pediatricians and public health researchers in five US cities (Boston, Baltimore, Little Rock, Minneapolis, and Philadelphia), we seek to improve the health and well-being of children under age 4 and their families by informing policies that address and alleviate economic hardships. Our ongoing data collection in emergency departments and primary care clinics enables us to rapidly respond to emerging public health issues as policies and economic conditions change. While we have produced other papers and analyses specifically addressing health and economic disparities relevant to immigrant families, we were specifically interested in exploring this topic because the clinicians in our group as well as national media began anecdotally reporting that immigrants were forgoing accessing critical public health programs like SNAP out of fear.

Author Interviews, Brain Cancer - Brain Tumors, Radiation Therapy, Surgical Research / 12.11.2018

MedicalResearch.com Interview with: Dr. Stephanie E. Weiss MD FASTRO Chief, Division of Neurologic Oncology Associate Professor, Department of Radiation Oncology Director, Radiation Oncology Residency and Fellowship Training Program Fox Chase Cancer Center Philadelphia, Pennsylvania MedicalResearch.com: What is the background for this study? Response: Brain metastasis are the most common form of brain tumor. Historically all patients received whole brain radiation as the primary therapy. Patients required neurosurgery to remove lesions if there was a question of diagnosis, what the diagnosis is and if there was a mass effect not relieved with steroids. Surgery was also indicated for patients with a single brain lesion because this offers a survival benefit over just receiving whole brain radiotherapy. In 2003 a randomized trial proved that radiosurgery offers a similar benefit. So the question taxing patients and doctors at tumor boards since has been: which is better? If neurosurgery is superior, we are under-treating a lot of patients with radiosurgery. If radiosurgery is superior, we are subjecting a lot of patients to unnecessary brain surgery. Attempts to study this in a head-to-head randomized trial have failed. Patient and physician preference for one treatment or the other has proven to be a barrier to randomization and accrual. The EORTC 22952-2600 trial was originally designed to compare outcomes with and without whole brain radiation for patients receiving surgery or radiosurgery for brain metastasis. We used this as the highest-quality source data available to compare local control of brain metastasis after surgery or radiosurgery, adjusted for by receipt or not of whole brain radiation.   (more…)
Author Interviews, Circadian Rhythm, Heart Disease / 11.11.2018

MedicalResearch.com Interview with: sunset copyright American Heart AssociationJay Chudow, M.D. Montefiore Medical Center Bronx, New York MedicalResearch.com: What is the background for this study? What are the main findings?
  • Others found associations between daylight saving time transitions and sleep duration, sleep quality, workplace injuries and traffic accidents. Regarding cardiovascular health, studies in Europe and the United States have found an increased incidence of acute myocardial infarction and ischemic stroke in the days following daylight saving time transitions.
  • Our study found a significant increase in admissions for atrial fibrillation following the daylight saving time spring transition compared to the yearly average (average of 3.13 vs 2.56 admissions per day over the Monday to Thursday period). No significant difference was found following the autumn transition.
  • These findings add atrial fibrillation as a known condition associated with daylight saving time transitions. It adds to the knowledge base of negative health consequences of daylight saving time.

Author Interviews, JAMA, Sexual Health / 11.11.2018

MedicalResearch.com Interview with: "Sex in stone" by Nagarjun Kandukuru is licensed under CC BY 2.0Janna A Dickenson, PhD Doug Braun-Harvey Postdoctoral Fellow Program in Human Sexuality Department of Family Medicine University of Minnesota Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: Researchers and clinicians have contested the term “sex addiction” in favor of alternative definitions and symptom presentations. Recently, the ICD-11 has characterized compulsive sexual behavior disorder (CSBD) as a persistent pattern that involves failing to control intense sexual urges or sexual behaviors that results in significant levels of distress and/or impairment in one’s functioning.
Researchers estimate that CSBD affects 2-6% of the population and is much more common among cisgender men than cisgender. Using a randomized national sample, we assessed the prevalence of a key feature of CSBD that researchers and clinicians agree upon: distress and impairment associated with difficulty controlling sexual feelings, urges, and behaviors.
We performed this assessment with a screening tool called the Compulsive Sexual Behavior Inventory (CSBI). Of the 2,325 adults, 8.6 percent overall (10.3 percent of individuals who identified as men and 7 percent of individuals who identified as women) met the clinical threshold of the CSBI; meaning that 8.6% of people expressed difficulty controlling their sexual feelings, urges and behaviors and experienced distress and/or impairment as a result. To be clear, this does not mean the 8.6% of the sample endorsed CSBD, but that 8.6% of our sample exhibited significant distress or impairment related to difficulty controlling one's sexual behaviors.

Aging, Author Interviews, Hearing Loss, JAMA / 11.11.2018

MedicalResearch.com Interview with: David Loughrey PhD Atlantic Fellow for Equity in Brain Health Global Brain Health Institute DeafHear Research Partner NEIL Programme Trinity College Institute of Neuroscience MedicalResearch.com: What is the background for this study? Response: The World Organisation (WHO) estimate that one-third of older adults aged 65 and over have a disabling hearing loss. Increasingly, research is finding that age-related hearing loss (ARHL) may be associated with other negative health outcomes, including dementia which currently affects 50 million people worldwide. A study recently published in The Lancet reported that of nine possible modifiable risk factors, addressing age-related hearing loss (ARHL) could potentially lead to the largest reduction in the prevalence of dementia globally.

Author Interviews, Heart Disease, Lifestyle & Health, Yale / 11.11.2018

MedicalResearch.com Interview with: Nikolaos Papoutsidakis, M.D., Ph.D. Associate Research Scientist, Yale University School of Medicine New Haven, CT  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Lifestyle education is a significant part of Hypertrophic Cardiomyopathy management. HCM patients, who frequently have to abstain from intense athletics, often ask if such restrictions extend to thrill-seeking activities they previously enjoyed, such as rollercoaster rides. Werealized there is very little data on this topic, which prompted us to set up this study. We found that for Hypertrophic Cardiomyopathy patients who elected to participate in thrill-seeking activities, adverse events (defined as losing consciousness or experiencing a shock from an implantable cardioverter-defibrillator) were rare. We also asked patients (participating and non participating) about advice received from their physician on this topic. We found that, probably due to the lack of data, physicians often avoid providing advice or provide conflicting advice regarding participation in thrill seeking activities.  (more…)

MedicalResearch.com Interview with: "Mammogram" by slgckgc is licensed under CC BY 2.0Prof. Cathrin Brisken MD, PhD ISREC, School of Life Sciences Ecole Polytechnique Fédérale (EPFL) CH-1015 Lausanne, Switzerland  MedicalResearch.com: What is the background for this study? Response: Estrogen receptor signaling has been well characterized in various in vitro models, like breast cancer cell lines.  Understanding estrogen receptor action in complex in vivo context is much more challenging. We obtained elegant mouse models in which either all estrogen receptor function or specifically either the hormone dependent (AF-2) or the hormone independent (AF-1) function were ablated. Using the mammary glands from these mice we performed tissue recombination studies to discern the role of the different aspects of estrogen receptor signaling in the mouse mammary epithelium and its different cell populations.

Response: This study is a follow-up study to our previous study where we found that chronic insufficient sleep together with chronic jet lag is associated with adverse changes in metabolism, including increase in blood sugar levels (Buxton et al. Science Translational Medicine, 2012). The present study focuses on the influence of the time of day on metabolism, which has not been investigated in humans independent of the effects of sleep, physical activity and diet. (more…)

MedicalResearch.com Interview with: Tom Marshall, MSc, PhD, MRCGP, FFPH Professor of public health and primary care Institute of Applied Health Research University of Birmingham, Birmingham, UK MedicalResearch.com: What is the background for this study?   Response: Tonsillectomy is one of the most common childhood surgical procedures. There are two main indications: recurrent sore throat and sleep-related breathing problems (including obstructive sleep apnoea). Jack Paradise’s 1984 study made clear tonsillectomy is modestly effective in children with frequent, severe sore throats: seven in one year, or five yearly in two successive years, or three yearly in three successive years. Sore throats must have symptoms: fever, pus seen on tonsils, lymphadenopathy or confirmed Streptococcal infection. With surgery, children average two sore throats in the next year, without surgery, three. Two years later there is no difference. Further research shows the benefits are too tiny to justify surgery in children with less frequent, less severe or undocumented sore throats. Subsequent randomised controlled trials have not changed the evidence. There isn’t enough good evidence to support surgery in children with obstructive sleep apnoea or sleep related breathing problems. Tonsillectomy is not a trivial procedure, about 2% are readmitted with haemorrhage and about 1 in 40,000 dies. Childhood tonsillectomy is linked to risk of adult autoimmune diseases. It is important to be sure tonsillectomy is only undertaken in children where there are evidence-based indications. (more…)

MedicalResearch.com Interview with: Jennifer P. Craig, Associate Professor Department of Ophthalmology New Zealand National Eye Centre Auckland, New Zealand MedicalResearch.com: What is the background for this study? Response: Dry eye disease is a complex multi-factorial condition, which affects between 5% to 50% of the adult population in different parts of the world. The condition can have profound effects on the ocular comfort, visual function, and quality of life of sufferers. In both clinical practice and academic research settings, validated questionnaires are frequently used to screen for dry eye symptomology, before clinical assessment of tear film homeostatic markers is conducted to make an overall diagnosis of dry eye disease. Although a large number of validated symptomology questionnaires has previously been developed, the recently convened Tear Film and Ocular Surface Dry Eye Workshop II (TFOS DEWS II) identified that the considerable heterogeneities in the study populations, methodologies, and reference standards used in earlier diagnostic accuracy studies introduced significant challenges when trying to compare the diagnostic performance of these screening instruments. The current study is the first to offer a direct comparison of five commonly used validated questionnaires within the same study population, and uses the global consensus criteria for tear film homeostatic disturbance developed by the TFOS DEWS II as the reference standard.

MedicalResearch.com Interview with: "Protect Coral Reefs" by NOAA's National Ocean Service is licensed under CC BY 2.0Ariel Kushmaro and Esti Kramarsky-Winter Department of Biotechnology Engineering, Ben Gurion University Beer Sheva, Israel The Republic of Palau, a South Pacific island nation, became the world's first country to ban sunscreen products containing environmentally harmful ingredients MedicalResearch.com: What is the background for this announcement? What are the main findings?  Response: Coral reefs are important ecosystems that are under threat due to global human driven climate change. In addition to global changes, local hazards such as point pollution by eutrophication, dredging and chemical pollution are exacerbating and promoting reef destruction at local levels. This destruction affects not only island nations that depend on these reefs for protection and livelihood, they affect humanity as a whole as they are an important source for food and novel drugs and new materials. Our recent studies have shown that chemicals found in most commercial sunscreens and creams used to protect humans from deleterious effects of UV A and UVB wash off into the environment are persistent, have endocrine disruptive effects, and thus deleteriously affect marine organisms including corals.  (more…)
