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.

MedicalResearch.com Interview with: "Compare-the-Use-of-Carbohydrates-and-Lipids-in-Energy-Storage" by Zappys Technology Solutions is licensed under CC BY 2.0Kirsi-Marja Zitting, Ph.D. Instructor in Medicine, Harvard Medical School Division of Sleep and Circadian Disorders Departments of Medicine and Neurology Brigham and Women’s Hospital Boston, MA 02115 MedicalResearch.com: What is the background for this study? 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…)
Author Interviews, BMJ, Obstructive Sleep Apnea, Pediatrics, Sleep Disorders, Surgical Research / 09.11.2018

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…)
Author Interviews, JAMA, Ophthalmology / 09.11.2018

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…)

MedicalResearch.com Interview with: Angela Mariotto PhD Chief of the Data Analytics Branch Surveillance Research Program (SRP) Division of Cancer Control and Population Sciences National Cancer Institute (NCI MedicalResearch.com: What is the background for this study? Response: Progressing to metastatic breast cancer (MBC) is one of the major concerns for women diagnosed with early-stage breast cancer. Before our study there were no reliable numbers on risk of metastatic breast cancer recurrence after a (non-metastatic) breast cancer diagnosis, as registries do not routinely collect this data.

Author Interviews, Infections, Pediatrics, Pulmonary Disease / 08.11.2018

MedicalResearch.com Interview with: Andrea Hahn, M.D., MS Infectious disease specialist and lead study author Children's National Health System MedicalResearch.com: What is the background for this study? What are the main findings? Response: People who have the genetic disease cystic fibrosis have increased sticky secretions in their lungs that put them at risk for repeated bacterial infections. They often will receive courses of intravenous antibiotics to treat more severe or difficult-to-treat infections associated with decreased lung function. However, not all patients fully recover their lung function after antibiotic treatment, despite directing antibiotic therapy toward the specific bacteria thought to be causing the infection. The goal of this study was to determine if the pharmacokinetics of commonly used antibiotics was associated with recovery of lung function. First, we found that patients with therapeutic blood levels of beta-lactam antibiotics had better lung recovery than patients with sub-therapeutic levels of these antibiotics. Second, we found that using higher antibiotic dosing according to Cystic Fibrosis Foundation guidelines was not sufficient to predict which patients would have therapeutically meaningful blood levels of antibiotics.

Author Interviews, Cost of Health Care, Duke, Geriatrics, Hearing Loss, Hospital Readmissions, JAMA / 08.11.2018

MedicalResearch.com Interview with: Nicholas S. Reed, AuD Assistant Professor | Department of Otolaryngology-Head/Neck Surgery Core Faculty | Cochlear Center for Hearing and Public Health Johns Hopkins University School of Medicine Johns Hopkins University Bloomberg School of Public Health MedicalResearch.com: What is the background for this study? Response: This study was a true team effort. It was funded by AARP and AARP Services, INC and the research was a collaboration of representatives from Johns Hopkins University, OptumLabs, University of California – San Francisco, and AARP Services, INC. Given all of the resent research on downstream effects of hearing loss on important health outcomes such as cognitive decline, falls, and dementia, the aim was to explore how persons with hearing loss interacted with the healthcare system in terms of cost and utilization. MedicalResearch.com: What are the main findings? Response: Over a 10 year period, untreated hearing loss (hearing aid users were excluded from this study as they are difficult to capture in the claims database) was associated with higher healthcare spending and utilization. Specifically, over 10 years, persons with untreated hearing loss spent 46.5% more, on average, on healthcare (to the tune of approximately $22000 more) than those without evidence of hearing loss. Furthermore, persons with untreated hearing loss had 44% and 17% higher risk for 30-day readmission and emergency department visit, respectively. Similar relationships were seen across other measures where persons with untreated hearing loss were more likely to be hospitalized and spent longer in the hospital compared to those without evidence of hearing loss.

Anesthesiology, Author Interviews, JAMA, Pediatrics, Surgical Research / 08.11.2018

MedicalResearch.com Interview with: "Anesthesia" by Liran Szeiman is licensed under CC BY-NC-ND 4.0James D. O’Leary, MD Department of Anesthesia and Pain Medicine, Child Health Evaluative Sciences The Hospital for Sick Children Department of Anesthesia, University of Toronto Toronto, Ontario, Canada MedicalResearch.com: What is the background for this study? What are the main findings? Response: There is substantial evidence from laboratory studies that the developing brain is susceptible to injury from general anesthetic drugs, which culminated in the US Food Drug Administration issuing a safety communication in 2017 stating that the use of general anaesthetic drugs “for lengthy periods of time or over multiple surgeries or procedures may negatively affect brain development in children younger than 3 years”. Considering the substantial number of children who require general anesthesia every year (almost 3 million in the US annually) even small differences in child development outcomes after surgical procedures that require general anesthesia may have significant public health implications. Undertaking studies of anesthesia-related neurotoxicity in humans is difficult as adverse child development is a function of the complex interaction between many risk and protective factors. By examining differences between biological siblings in Ontario, Canada, this study seeks to mitigate differences in risk from biological vulnerability and environmental factors, to provide a more accurate estimate of the adverse effects of anesthesia and surgery on child development. In the current study, young children who had surgical procedures that require general anesthesia were not found to be at increased risk of adverse child development outcomes compared to their biological siblings who did not have surgery. These findings further support that exposure to anesthesia and surgery in early childhood is not associated with detectable adverse child development outcomes. (more…)
Alcohol, Author Interviews / 08.11.2018

MedicalResearch.com Interview with: “Alcohol” by Jorge Mejía peralta is licensed under CC BY 2.0Sarah Hartz, MD PhD Assistant Professor Department of Psychiatry Washington University School of Medicine in St. Louis MedicalResearch.com: What is the background for this study? What are the main findings?  Response: This study is the first to show that daily drinking is dangerous. Specifically, drinking four or more times weekly, even if it’s only 1-2 drinks at a time, increases risk of mortality. This is in line with recent studies published in the Lancet, but we were able to break down their lowest drinking categories (up to 12.5 drinks weekly in one and up to 5.6 drinks weekly in the other) and found that the frequency is important, not just the average number of drinks per week. It looks like the increased mortality is predominantly due to cancer-related deaths. (more…)
Author Interviews, Brain Injury / 08.11.2018

MedicalResearch.com Interview with: Clara E. Dismuke-Greer, PhD Health Equity and Rural Outreach Innovation Center Ralph H. Johnson Department of Veterans Affairs Medical Center Charleston, SC 29401 MedicalResearch.com: What is the background for this study? What are the main findings? Response: The background for this study is that previous research we had published had shown that Hispanic U.S. Veterans diagnosed with Traumatic Brain Injury (TBI) had higher risk of mortality than non-Hispanic White U.S. Veterans, even after accounting for the effects of comorbidities as well as socio-demographics. This study sought to investigate further this apparent racial/ethnic disparity. Using a 10 year cohort followed for up to 14 years, and adjusting for TBI severity as well as comorbidities, socio-demographics and military factors, when we included location (urban vs. rural vs. highly rural vs. U.S. Territory (Puerto Rico, U.S. Virgin Islands, Guam, America Samoa and Mariana Islands), as well as race/ethnicity, we found that the racial/ethnic disparity disappeared, and that it was location which became statistically significant. Our main findings were that Veterans diagnosed with TBI residing in U.S. Territories have lower survival and higher risk of mortality relative to Veterans residing on the U.S. Mainland , even after statistical adjustment for the factors listed above.

Author Interviews, NEJM, STD / 07.11.2018

MedicalResearch.com Interview with: Edward W. Hook, III, MD University of Alabama at Birmingham Medicine / Infectious Diseases Birmingham, AL MedicalResearch.com: What is the background for this study? What are the main findings? Response: Zoliflodacin represents a new class of antibiotics (spiropyrimidinetriones) with in vitro activity against Neisseria gonorrhoeae, as well as other STD  pathogens (Chlamydia trachomatis and Mycoplasma genitalium).  Because of this promising data and the fact that the manufacturer (Entasis Pharmaceuticals) was willing to pursue the possibility of using this drug to treat gonorrhea, a Phase II trial was conducted which showed he drug to be 96% effective for genital or rectal infections.  The drug was well tolerated as well making it a promising drug for gonorrhea treatment which might help to combat the increasing problem of antibiotic resistant gonorrhea.  (more…)
Author Interviews, JAMA, Opiods, Surgical Research, University of Michigan / 07.11.2018

MedicalResearch.com Interview with: Joceline Vu, MD Resident, PGY-5 Department of Surgery University of Michigan  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: This study examined how much opioid patients use after surgery, and looked at factors that might predispose some patients to use more or less. Patient opioid use after surgery is an interesting question that’s gained a lot of attention recently, because it’s different from other uses for opioids. If you have chronic pain, you’re probably going to use all of your prescription. But if you have surgery, you may not take all of your pills, and this leaves people with leftover pills that can be dangerous later. From this study, we found that patients only use, on average, about quarter of their prescription, meaning that a lot of them are left with leftover pills. Moreover, we found that the biggest determinant of how much they used wasn’t how much pain they reported, or any other factor—it was how big their original prescription was. What this means is that opioid use after surgery isn’t just determined by pain, but also by what surgeons prescribe. It’s important to keep this in mind as we try to reduce unnecessary opioid prescribing after surgical procedures.  (more…)

MedicalResearch.com Interview with: Dr. Jean Philippe Empana, MD, PhD Research Director, INSERM U970 Paris Cardiovascular Research Center (PARCC) Team 4 Cardiovascular Epidemiology & Sudden Death Paris Descartes University MedicalResearch.com: What is the background for this study?  Response: In 2010, the American Heart Association (AHA) has emphasized the primary importance of the Primordial prevention concept, i.e. preventing the development of risk factors before they emerge, as a complementary prevention strategy for cardiovascular disease (CVD). Accordingly, the AHA has developed a simple 7-item tool, including 4 behavioral (nonsmoking, and ideal levels of body weight, physical activity and diet) and 3 biological metrics (ideal levels of untreated blood pressure, fasting blood glucose and total cholesterol) for promoting an optimal cardiovascular health (CVH). The relevance of the concept and of the tool has been several times reported by individual studies and meta-analyses (combining the results of several studies) showing substantial and graded benefit for cardiovascular disease but also mortality, quality of life and even cancer risk with higher level of CVH. However, most studies relied on one measure of  cardiovascular health. In the present work, using serial examinations from the well-known Whitehall Study II, we described change in CVH over time and then quantified the association of change in cardiovascular health over 10 years with subsequent incident cardiovascular disease and mortality. This analysis is based on 9256 UK men and women aged 30 to 55 in 1985-88, and thereafter examined every 5 years on average during 30 years. (more…)

MedicalResearch.com Interview with: "Cockroaches at night" by Sigurd Tao Lyngse is licensed under CC BY 2.0Changlu Wang, PhD The Urban Entomology lab Department of Entomology Rutgers University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Cockroaches are an important public health pest. They carry pathogens and produce allergens which causes asthma. Some residential communities always have chronic cockroach infestations. This study is designed to understand the environmental and behavioral factors associated with cockroaches in low-income homes occupied by senior citizens. We found 30% of the 388 surveyed homes had German cockroaches. Sanitation and residents’ tolerance are two factors significantly associated with the presence of cockroaches. A dirty apartment is 2.7 times more likely to have German cockroaches. Gender, ethnicity, and clutter level are not associated with presence of cockroaches. People would be bothered by cockroaches when more than 3 cockroaches are caught in sticky traps when 4 traps were placed per apartment over 2 weeks period. A high percentage (36%) of residents were unaware of cockroaches when they were caught in traps in their homes. These findings are important for property managers and policy makers in designing better intervention methods to reduce the cockroach infestations.  (more…)
