Author Interviews, Diabetes, JAMA, Lifestyle & Health / 09.11.2017

MedicalResearch.com Interview with: Dr. Karla Galaviz PhD Hubert Department of Global Health Rollins School of Public Health Emory University Sonya Haw, MD| Assistant Professor Division of Endocrinology, Metabolism & Lipids Emory University, School of Medicine Grady Memorial Hospital Atlanta, GA MedicalResearch.com: What is the background for this study? What are the main findings?
  • Diabetes affects 1 in 11 adults worldwide and though there is evidence that lifestyle modification (eating healthier diets and exercising about 150 mins a week) and certain medications can prevent or delay diabetes onset, it is not clear which of these strategies offers long-term benefits.
  • To answer this question, we compiled all available randomized controlled trials of lifestyle programs and medications to prevent diabetes and analyzed the data to see if the diabetes prevention effects persisted in the long-term. We specifically compared studies where the lifestyle or drug interventions were discontinued to see if the effect was long lasting or diminished when the intervention was stopped.

Author Interviews, Menopause, Obstructive Sleep Apnea / 09.11.2017

MedicalResearch.com Interview with: Stephanie S. Faubion, MD, FACP, NCMP, IF Director, Executive and International Medicine Director, Office of Women’s Health Associate Professor of Medicine Division of General Internal Medicine  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The Data Registry on Experiences of Aging, Menopause and Sexuality (DREAMS) was used for this study investigating the association between vasomotor symptoms (hot flashes and night sweats) and risk for obstructive sleep apnea, a common and underdiagnosed sleep disorder in women which is associated with increased cardiovascular risk. We found that Women who had severe or very severe hot flashes or night sweats were more likely to be at increased risk for obstructive sleep apnea.  This association held even after adjusting for age, body mass index, smoking and hypertension, such that the odds of women having intermediate /high risk for obstructive sleep apnea were 1.87 times higher for those with severe/very severe hot flashes/night sweats compared to those with less severe symptoms.  We decided to analyze the group of women with normal body mass index, and indeed, this finding was still significant in the lean group of women.

Author Interviews, CDC, Environmental Risks / 09.11.2017

MedicalResearch.com Interview with: “Wood for Heat” by Alternative Heat is licensed under CC BY 2.0Ethel V. Taylor, DVM, MPH Division of Environmental Hazards and Health Effects National Center for Environmental Health, Centers for Disease Control and Prevention Atlanta, GA MedicalResearch.com: What is the background for this study? Response: CDC sought to identify and measure whether or not differences exist for deaths associated with extreme heat among non-citizens, who had been identified by previous studies as higher risk due to occupation. CDC compared heat-related deaths among non-US and US citizens from 2005-2014. Heat-related deaths accounted for 2.4% of all deaths among non-U.S. citizens (n=999) compared to 0.02% of U.S. citizens (n=4196). (more…)
Author Interviews, Biomarkers, Brain Injury, Lancet / 09.11.2017

MedicalResearch.com Interview with: Prof.dr. J van der Naalt PhD Department of Neurology University Medical Center Groningen Groningen, The Netherlands MedicalResearch.com: What is the background for this study? What are the main findings? Response: Mild traumatic brain injury occurs frequently and is one of the leading cause of morbidity in adults worldwide. It is a major social-economic problem with one in three patients had persistent complaints several months after injury that interfere with resumption of daily activities and work. One of the most important questions concerns the finding that some patients recover without complaints and others do not after sustaining a mild traumatic brain injury. In a follow-up study with more than 1000 participants we found that personality factors are a major factor in the recovery process. In particular coping, that is the way patients adapt to persistent complaints, is important next to emotional distress and impact of the injury. In an add-on study with fMRI we found that in the early phase after injury, the interaction between specific brain networks was temporarily changed. However, when regarding persistent posttraumatic complaints , specific personality characteristics significantly determine long term outcome. (more…)
Author Interviews, HIV, Mental Health Research, Pediatrics / 08.11.2017

MedicalResearch.com Interview with: Marcin Jankiewicz  University of Cape Town Cape Town, South AfricaMarcin Jankiewicz  University of Cape Town Cape Town, South Africa  MedicalResearch.com: What is the background for this study? Response: The Children with HIV Early Antiretroviral (CHER) trial, conducted in Cape Town and Soweto, was designed when there was uncertainty whether to start antiretroviral therapy (ART) as soon as HIV was diagnosed (below 12 weeks of age) or to wait until there was evidence of immuno-compromise and disease progression. Also, there were concerns about maintaining adherence, long-term toxicity and also resistance in the setting of few antiretroviral options. Early outcomes showed a decreased risk in childhood mortality in the early treatment arms compared to deferred treatment, becoming standard of care globally. The CHER cohort is one of the largest and best documented of children receiving ART within the first year of life. Also, age- and community-matched HIV exposed uninfected (HEU) and HIV unexposed (HU) uninfected infants were enrolled in parallel for a linked vaccine study. We therefore had an amazing opportunity to link with a neurodevelopmental sub-study in participants from Cape Town and apply sophisticated neuroimaging modalities that could link with clinical, virological and immunological characteristics.

Author Interviews, Breast Cancer / 08.11.2017

MedicalResearch.com Interview with: Dr Hongchao Pan PhD Medical Research Council Population Health Research Unit Clinical Trial Service Unit & Epidemiological Studies Unit Nuffield Department of Population Health Oxford MedicalResearch.com: What is the background for this study? What are the main findings? Response: We’ve known for a long time that recurrences can occur late in women with oestrogen receptor positive breast cancers. Our study aimed to assess how big the risk was for women who had taken endocrine treatment (tamoxifen or an aromatase inhibitor) for 5 years, which greatly reduces the risk of recurrence (by about a half during treatment and one third for the 5 years after stopping). We also wanted to find out what factors influenced the risk of recurrence, and whether some women had such a low risk that they could safely stop hormonal treatment after 5 years or, conversely, whether other women had a particularly high risk so it would make sense for them to keep on taking hormonal treatment. What we found by following the progress of over 60,000 women who had stopped hormonal treatment at 5 years is that the risk of the cancer spreading stays about the same for the next 15 years. This risk is much higher for women whose breast cancer had spread to the nodes when first diagnosed but even for those with the best outlook (no spread to the lymph nodes and small tumours), there was a 10% chance of cancer spread over 15 years.

Author Interviews, Depression, Kidney Disease, UT Southwestern / 08.11.2017

MedicalResearch.com Interview with: Dr. Susan Hedayati MD Yin Quan-Yuen Distinguished Professorship in Nephrology University of Texas Southwestern Dallas, Texas MedicalResearch.com: What is the background for this study? What are the main findings? Response: We previously showed that Major Depression is associated with a significantly higher risk of death, dialysis initiation, and hospitalization among patients with Chronic Kidney Disease (CKD). Now we show that a common antidepressant medication, a selective serotonin reuptake inhibitors (SSRI), sertraline, does not improve depression in this patient population, a chronically ill group that is not only at significantly increased risk for developing depression but also its serious complications.

AHA Journals, Author Interviews, Brigham & Women's - Harvard, Exercise - Fitness, Lifestyle & Health / 08.11.2017

MedicalResearch.com Interview with: I-Min Lee, MD, ScD Professor of Medicine, Harvard Medical School Professor of Epidemiology, Harvard T.H. Chan School of Public Health Brigham and Women's Hospital Boston, MA 02215 MedicalResearch.com: What is the background for this study? What are the main findings? Response: The fact that physical activity lowers the risk of premature mortality is not a new fact – we have many studies showing this.  However, previous studies have primarily relied on self-reported physical activity, and self-reports tend to be imprecise.  Based on these self-report studies, we know that physical activity is associated with a 20-30% reduction in mortality rates.  And, these self-report studies also have focused on moderate-to-vigorous intensity physical activity, since they are more reliably reported than lighter intensity activity.  We have little information on whether light-intensity activities (e.g., light household chores, very slow walking such as when strolling and window shopping) are associated with lower mortality rates. We now have “wearables” – devices that can more precisely measure physical activity at low (as well as higher) intensities, and sedentary behavior.  The present study, conducted between 2011 and 2015, investigated a large cohort of older women (n=16,741; mean age, 72 years)  who were asked to wear these devices for a week – thus, providing detailed physical activity and sedentary behavior measures.  During an average follow-up of about two-and-a-half years, 207 women died.  The study confirmed that physical activity is related to lower mortality rates. What is new and important is how strong this association is when we have more precise measures of physical activity – the most active women had a 60-70% reduction in mortality rates, compared with the least active, during the study.  For context, non-smokers have about a 50% risk reduction, compared to smokers, which is why patients (and doctors) should pay attention to being physically active.

Author Interviews, Gastrointestinal Disease, JAMA, Lymphoma / 08.11.2017

MedicalResearch.com Interview with: ANSMRosemary Dray-Spira, MD, PhD Department of Epidemiology French National Agency for Medicines and Health Products Safety (ANSM) Saint-Denis, France MedicalResearch.com: What is the background for this study? What are the main findings? Response: Anti-tumor necrosis factor (anti-TNF) agents are increasingly used for the management of inflammatory bowel diseases (IBD), either alone or in combination with thiopurines. Their clinical benefits have been largely assessed, however they may expose to potentially serious adverse effects. While an increased risk of lymphoma has been established with thiopurines, up to now such a risk of lymphoma remained uncertain with anti-TNF agents. In this study based upon a large, nationwide cohort of 189,289 patients with IBD, the use of anti-TNF agents alone was found associated with a 2 to 3 fold increase in the risk of lymphoma, similarly to thiopurines alone. In addition, the combination of these two treatments was associated with a 6 fold increase in the risk of lymphoma, ie a higher risk than with each treatment used alone. Although these differences are statistically significant, the risk of lymphoma among patients exposed to anti-TNF agents is less than 1 case per 1000 person-years. (more…)
Author Interviews, Cannabis, JAMA / 08.11.2017

MedicalResearch.com Interview with: Marcel Bonn-Miller, PhD Adjunct assistant professor Department of Psychiatry Leader of the Substance Abuse and Anxiety Program U.S. Veterans Affairs Department  MedicalResearch.com: What is the background for this study? What are the main findings? Response: A 2015 study found that edible cannabis products (e.g., brownies, cookies, drinks) are often mislabeled.  The FDA has also sent warning letters to a handful of companies selling cannabidiol extracts because of inaccurate labeling of content. This led us to conduct a systematic evaluation of the label accuracy of all cannabidiol extracts sold online.  We tested 84 products from 31 different companies. The primary take-home of this study is that nearly 70 percent of all cannabidiol extracts sold online had over 10% more or less cannabidiol than advertised; 26% of products were over-labeled (less cannabidiol than indicated) and 42% of products were under-labeled (more cannabidiol than indicated).

MedicalResearch.com Interview with: “Dymchurch Beach - May 2012 - Sunburn with Matching Bikini” by Gareth Williams is licensed under CC BY 2.0Dawn M. Holman, MPH Behavioral Scientist Division of Cancer Prevention and Control Centers for Disease Control and Prevention MedicalResearch.com: What is the background for this study? Response: Scientific evidence clearly shows that even one sunburn during adolescence can increase a person’s chances of developing skin cancer as an adult. Surprisingly, little research has been done to understand the factors associated with sunburn during this phase of life. The CDC wanted to examine beliefs, behaviors, and demographic characteristics that might be associated with adolescent sunburns in hopes that the findings could inform future intervention efforts. We used data from the 2015 YouthStyles survey (adolescents aged 12 to 17 years) to explore this research question (more…)
Author Interviews, CDC, Diabetes, Kidney Disease / 08.11.2017

MedicalResearch.com Interview with: Nilka Ríos Burrows, MPH, MT (ASCP) Lead, Chronic Kidney Disease Initiative CDC Division of Diabetes Translation.  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Kidney failure treated with dialysis or a kidney transplant is called end-stage renal disease (ESRD).  ESRD is a costly and disabling condition often resulting in premature death. During 2000–2014, kidney failure from diabetes among U.S. adults with diabetes decreased by 33%, and it declined significantly in most states, the District of Columbia, and Puerto Rico. No state experienced an increase in kidney failure from diabetes. Continued awareness and interventions to reduce risk factors for kidney failure, improve diabetes care, and prevent type 2 diabetes might sustain these positive trends. (more…)
Author Interviews, Orthopedics, Rheumatology, Social Issues / 07.11.2017

MedicalResearch.com Interview with: Susan M. Goodman, MD Director of the Integrative Rheumatology and Orthopedics Center of Excellence Hospital for Special Surgery  MedicalResearch.com: What is the background for this study? What are the main findings? Response: We have previously reported that African Americans who have poorer health outcomes, may be disproportionately impacted by community factors. For African Americans undergoing knee replacement, no difference in pain and function was seen compared to whites in communities with little poverty, while in poor communities, African Americans had poorer outcomes. We wondered if this was generally true or if this only applied to knee replacements. We found similar results; African Americans in richer neighborhoods have comparable outcomes to whites, but as poverty increases- in this study measured as percent with Medicaid coverage- outcomes worsen in a step wise fashion.

Author Interviews, Autism, Pharmacology / 07.11.2017

MedicalResearch.com Interview with: Dr. Mark E. Gurney, PhD MBA Chairman & CEO, Tetra Discovery Partners Inc. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Fragile X is a genetic condition. Affected patients display a range of behavioral and other symptoms, including seizures, sleep disorders, anxiety, irritability, hyperactivity, autism, mild-to-severe cognitive impairment and intellectual disability. BPN14770 is a novel therapeutic agent that selectively inhibits phosphodiesterase-4D (PDE4D). Inhibition of PDE4 has been validated as a treatment strategy by many research groups in the Fragile X field, but non-selective PDE4 inhibitors have been associated with significant GI side-effects that have limited those drugs’ use. As a selective inhibitor, such side-effects were not seen for BPN14770 in a Phase 1 clinical trial in healthy young and elderly adults. In the current study, daily treatment of Fragile X knock-out (FXS) mice with BPN14770 showed a reduction in hyperarousal, improved social interactions and natural behaviors, and changes in nerve structure in the prefrontal cortex of the brain, the portion of that brain associated with cognition. Moreover, the drug’s benefit persisted for two weeks after all drug was cleared from the mice. At the same time, the behavior of normal mice treated with the drug remained unchanged. Examination of neurons from the prefrontal cortex of the treated FXS mice showed an improvement in dendritic spine morphology. (more…)

MedicalResearch.com Interview with: Dr. Stephen M. Rose, PhD Chief Research Officer Foundation Fighting BlindnessDr. Stephen M. Rose, PhD Chief Research Officer Foundation Fighting Blindness Dr. Rose discusses the FDA advisory panel unanimously recommended approval of Spark Therapeutics' Gene Therapy Luxturna  for the treatment of patients with vision loss due to confirmed biallelic RPE65-mediated inherited retinal dystrophies, a group of rare blinding conditions caused by one of more than 220 different genes. MedicalResearch.com: Would you tell us a little about IRD? Whom does it affect and how?  How common is this disorder? Response: The retina at the back of the eye is responsible for collecting light and turning it into signals that are transmitted to the brain and interpreted as vision. Think of the retina as the film in a camera, or more recently the sensor at the back of a digital camera. Inherited rare retinal degenerations are when the retina at the back of the eye deteriorates and loses its ability to capture light, thereby leading to blindness. iRDs can affect anyone, no matter race or ethnicity. These are inherited conditions that are passed down from parents to children, if a parent or both parents are either affected already or are carriers for a variant in any of the over 250 genes responsible for retinal degeneration. There are over 15 different types of iRDs, with retinitis pigmentosa being the most common with a US affected population around 100,000. The rest of the iRDs make up another approximately 100,000 affected individuals in the US, so there are about 200,000 total affected individuals in the US. Worldwide these iRDs affect somewhere around one to two million individuals. (more…)
Author Interviews, Brigham & Women's - Harvard, Cannabis, Pediatrics, Pediatrics / 07.11.2017

MedicalResearch.com Interview with: Shane Shucheng Wong, MD Massachusetts General Hospital Boston, Massachusetts  MedicalResearch.com: What is the background for this study? Response: Medical cannabis is now legal in 29 states and the District of Columbia, and in those areas with active programs, children and adolescents can legally access medical cannabis with certification from their doctor and consent from a parent. This means that doctors and families need to understand what we know and what we don’t yet know about medical cannabis in order to make the best decision for the health of the individual child. Two synthetic cannabinoids – compounds that act on specific receptors in the brain – have been approved for medical use in the U.S., both of which mimic a form of THC (tetrahydrocannabinol), the compound responsible for the “high” of recreational cannabis use. Dronabinol (Marinol) is approved to treat chemotherapy-induced nausea and vomiting in both children and adults, while the pediatric use of nabilone (Cesamet) carries a caution. A third cannabinoid, cannabidiol, is currently in phase 3 trials for treatment of seizures. (more…)

MedicalResearch.com Interview with: Andrea C. Tricco PhD, MSc Scientist and Lead of the Knowledge Synthesis Team Associate Professor Dalla Lana School of Public Health, University of Toronto Associate Editor Journal of Clinical Epidemiology, BMC Medical Research Methodology, Systematic Reviews MedicalResearch.com: What is the background for this study? Response: Falls are the leading cause of injury among older adults and account for $2 billion in direct health-care costs annually ($31 billion in costs to Medicare in the United States in 2012). We aimed to determine which types of fall-prevention programs may be effective for reducing falls in older people. MedicalResearch.com: What are the main findings? Response: Exercise, along with vision assessment and treatment, as well as an assessment and possible modification of a person’s living environment, reduced the risk of injurious falls by 23% compared to usual care.

MedicalResearch.com Interview with: Dr. Wai Keung Leung Professor, Division of Gastroenterology & Hepatology Department of Medicine Assistant Dean, LKS Faculty of Medicine University of Hong Kong Hong Kong MedicalResearch.com: What is the background for this study? What are the main findings? Response: It remains controversial whether proton pump inhibitors will increase the risk of gastric cancer. Although previous studies have shown a possible increase in risk in patients taking long-term proton pump inhibitors (PPI), these studies are confounded by the presence of H. pylori infection. In this population-based study from Hong Kong, we have determined the risk of gastric cancer development in more than 63,000 H. pylori-infected subjects who had the bacterium eradicated by a course of  clarithromycin-based triple therapy and continued to take PPI or H2-receptor antagonist (H2RA). After adjusting for various baseline differences among those PPI and non-PPI users, we found that the risk of gastric cancer was increased by 2.4-fold in those who used long-term PPI. The risk was in tandem with the frequency and duration of PPIs treatment. The risk increased from 5-fold to 8-fold for more than 1-year and 3-year use of PPI, respectively. Similar increase in risk was not observed among those who took H2RA, a weaker acid suppressive agent. (more…)

MedicalResearch.com Interview with: Dr. Keun-Hwa Jung MD PhD Program in Neuroscience, Neuroscience Research Institute of SNUMRC College of Medicine Seoul National University First author: Dr. Woo-Jin Lee MD Department of Neurology Seoul National University Hospital Seoul, South Korea  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Cerebral white matter hyperintensity is a prevalent consequence of brain aging process and associated with various complications. One of the main mechanisms underlying the progression of white matter hyperintensity is chronic dysfunction of the glymphatic system which maintains metabolic homeostasis in brain. Glymphatic system is the route where the cerebrospinal fluid enters into the brain parenchyma and is cleared out with soluble wastes to the perivascular space of the cerebral small veins, peri-meningeal lymphatic vessels, deep cervical lymph nodes, and finally to the right atrium. Although the integrity of the glymphatic system is dependent on the adequate drainage of cerebral veins and lymphatics to the downstream chamber, the right atrium, the impact of hemodynamic changes in right-sided cardiac chambers on the development of white matter hyperintensity have not been elucidated.

Alzheimer's - Dementia, Author Interviews, Cognitive Issues, Genetic Research, Nature / 07.11.2017

MedicalResearch.com Interview with: Dr Miguel Chillon PhD Department of Biochemistry and Molecular Biology Universitat Autonoma Barcelona Spain MedicalResearch.com: What is the background for this study? What are the main findings? Response: Klotho is a protein with an anti-aging and neuroprotective role. Recent studies show it prevents the development of cognitive problems associated with aging and Alzheimer's disease. Klotho works mainly by inhibiting the insulin / IGF-1 signaling pathway and decreasing the damage caused by oxidative stress in the brain. One of the latest results revealed that the concentration of Klotho in cerebrospinal fluid is significantly lower in Alzheimer's patients than in human controls of the same age; and it is lower in the elderly with respect to young adults. Our study used a gene therapy strategy to introduce the Klotho gene into the Central Nervous System of adult animals. With just a single injection of the Klotho gene, young adult animals were protected over time from the cognitive decline associated with aging in old animals. These exciting results pave the way to further advances in research and the development of a neuroprotective therapy based on Klotho. (more…)
Author Interviews, JAMA, Smoking, Tobacco Research / 07.11.2017

MedicalResearch.com Interview with: “Stop smoking!” by Emil_95 is licensed under CC BY 2.0Dr. Man Ping Wang, PhD School of Nursing University of Hong Kong Hong Kong MedicalResearch.com: What is the background for this study? What are the main findings? Response: Smoking cessation (SC) services can effectively increase the chance of abstinence, but few smokers proactively seek help from these services worldwide. Smoking cessation guidelines recommend referring smokers to SC services, but such referrals were usually conducted in a passive way (e.g. providing contacts of these services and asking smokers to use them). Actively referring smokers may increase use of smoking cessation services and abstinence rates. Previous studies were mostly conducted in clinical settings. We investigated the efficacy of using trained volunteers to actively refer smokers recruited in the community to smoking cessation services in this cluster randomized control trial. We found that smokers who received a brief cessation advice and active referral had significantly higher abstinence rate and smoking cessation service use rate at 6-month follow-up, compared with smokers who received a minimal advice and a self-help booklet.

Author Interviews, Dental Research, Genetic Research / 07.11.2017

MedicalResearch.com Interview with: “Dental Mold_002” by Ano Lobb is licensed under CC BY 2.0Alexandre R. Vieira, DDS. MS, PhD Professor, Director of Clinical Research,  Director of Student Research Department of Oral Biology Center for Craniofacial and Dental Genetics Department of Pediatric Dentistry School of Dental Medicine Department of Human Genetics Graduate School of Public Health Clinical and Translational Sciences Institute University of Pittsburgh  MedicalResearch.com: What is the background for this study? What are the main findings? Response: One aspect is the dilemma between continuing to use dental amalgams and the perception that composite resins are not as durable. We show that composite resin restorations can perform similarly to dental amalgams for the first 5 years. But the most remarkable is that composite resin failures may be related to certain individual risk factors, such as genetic variation. (more…)
Author Interviews, Heart Disease / 07.11.2017

MedicalResearch.com Interview with: Nayan Agarwal MD Intervention Cardiology Fellow University of Florida, Gainesville, FL MedicalResearch.com: What is the background for this study? What are the main findings? Response: Optimal antiplatelet strategy post CABG remains controversial with guidelines still evolving. Though aspirin monotherapy is the therapy of choice, but some studies have suggested a benefit of dual antiplatelet (DAPT). Question also remains if choice of antiplatelet therapy strategy is influenced by clinical presentation (acute coronary syndrome [ACS] versus non ACS) or CABG technique ( off pump versus on pump). The current meta-analysis of 8 randomized control trials and 9 observational studies with a total of 11,135 patients demonstrated that at a mean follow up of 23 months, major adverse cardiac events (MACE) (10.3% versus 12.1%, RR 0.84, confidence interval (CI) 0.71-0.99); all-cause mortality (5.7% versus 7.0%, RR 0.67, CI 0.48-0.94) and graft occlusion (11.3% versus 14.2%, RR- 0.79, CI- 0.63- 0.98) were less with DAPT compared with aspirin monotherapy. There was no difference in myocardial infarction, stroke, or major bleeding between the 2 groups. Subgroup analysis demonstrated that benefit of DAPT was independent of clinical presentation (ACS versus non ACS) or CABG technique (off pump versus on pump). (more…)

MedicalResearch.com Interview with: Themed Merchandised products affectedDr Andrew Turner Reader in Environmental Science (Biogeochemistry and Toxicology) School of Geography, Earth and Environmental Sciences University of Plymouth, UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: We had a project looking at toxic metals in consumer plastics and paints and as part of the study analysed decorated glassware product. With respect to the latter, and from a health perspective, it is concerning that metals that have been banned or restricted by so many industries over the past few decades are still used to decorate contemporary drinking glassware. Drinking glasses that are most hazardous are those where the décor extends into the lip area within 2 cm of the rim, and those that target children. (more…)

MedicalResearch.com Interview with: Daniel P. Schauer, MD, MSc Associate Professor, Internal Medicine University of Cincinnati College of Medicine Division of General Internal Medicine Cincinnati OH 45267-0535 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Obesity is associated with many types of cancer and bariatric surgery is the most effective treatment for severe obesity.  We conducted a retrospective cohort study of patients undergoing bariatric surgery between 2005 and 2012 with follow-up through 2014 using data from Kaiser Permanente using 5 study sites. The study included 22,198 patients who had bariatric surgery matched to 66,427 nonsurgical patients with severe obesity. We found that bariatric surgery was associated with a reduced risk of cancer.  The risk reduction was greatest for the cancers that are associated with obesity including postmenopausal breast, endometrial, colon, and pancreatic cancers, as well as esophageal adenocarcinoma.

AHA Journals, Author Interviews, Gender Differences, Lipids, Menopause / 06.11.2017

MedicalResearch.com Interview with: Marija Glisic Epidemiology, Erasmus MC  MedicalResearch.com: What is the background for this study? Response: Carotid atherosclerosis is one of most important risk factors for developing stroke. Carotid atherosclerotic plaques characterized by lipid core presence and intraplaque haemorrhage are considered to be unstable, and therefore more prone to rupture and lead to consequent stroke. Sex differences have been observed in carotid plaque composition as well as in stroke incidence. Sex hormones, particularly estrogen and testosterone actions are suggested to underlie the observed sex differences in atherosclerosis. Experimental evidence suggests a direct action of estradiol and testosterone on the vascular system, affecting various mechanisms that may impact plaque composition and subsequently stroke risk.

MedicalResearch.com Interview with: Eamonn M.M. Quigley, M.D. Director, Lynda K. and David M. Underwood Center for Digestive Disorders Houston Methodist Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: The BURDEN IBS-C (Better Understanding and Recognition of the Disconnects, Experiences, and Needs of Patients with Irritable Bowel Syndrome with Constipation) Study was designed to develop a better understanding of the experiences and attitudes associated with IBS-C. This study consisted of more than 1,300 individuals who met IBS-C criteria (mean age 46 years; 73 percent of respondents were female) and completed the author-developed, IRB-approved online questionnaire. The study also evaluated, through an approximately 45-minute long questionnaire, more than 325 healthcare providers who treat patients with IBS-C. Notably, the study found many patients experienced stress, lost productivity and described a feeling of frustration with their condition. HCPs recognize this frustration, yet underestimate how many patients have “accepted” their condition. Both patients and healthcare providers (HCPs) also noted a lack of satisfaction in currently available prescription treatments for IBS-C. Detailed findings can be found here. (more…)
Author Interviews, JAMA, Pediatrics / 06.11.2017

MedicalResearch.com Interview with: Sally H. Adams, PhD, RN Specialist, Division of Adolescent and Young Adult  Medicine Adolescent and Young Adult Health National Resource Center University of California, San Francisco Benioff Children’s Hospital San Francisco, CA 94118 MedicalResearch.com: What is the background for this study? Response: Major causes of adolescent illness and mortality are preventable. To address this, in the 1990s, professional medical organizations developed healthcare provider guidelines for the delivery of adolescent preventive healthcare. These include the receipt of anticipatory guidance and risk screening services in the effort to promote healthy behaviors and avoid risky behaviors that are intended to be covered within a preventive care visit, but could be addressed in other healthcare visits. The adolescent developmental period is an important time for adolescents to be engaged with the healthcare system. Transitioning from childhood to adulthood, adolescents are becoming increasingly independent - having more responsibility and freedom for decision making in many areas, including healthy choices in behaviors and activities. While families and community settings (schools, churches) play strong roles in this process, the healthcare system also plays an important role. (more…)
