W. Katherine Yih Ph.D., M.P.H Department of Population Medicine Harvard Medical School and Harvard Pilgrim Health Care InstituteMedicalResearch.com Interview with: W. Katherine Yih Ph.D., M.P.H Department of Population Medicine Harvard Medical School and Harvard Pilgrim Health Care Institute MedicalResearch.com: What are the main findings of the study?Dr. Yih: The main findings are that vaccination with the first dose of RotaTeq is associated with a small increase in the risk of intussusception, which is concentrated in the first week after vaccination. The estimated risk is about 1.5 excess cases per 100,000 first doses administered. This risk is fairly small, amounting to roughly 1/10 of the risk seen after the original rotavirus vaccine (called Rotashield) that was used in 1998-1999, before it was withdrawn from the market.We also found evidence that Rotarix increases the risk of intussusception. However, the number of infants receiving Rotarix and the number getting intussusception after Rotarix were too small to allow us to estimate the risk after Rotarix with any precision. (more…)

Jyrki Virtanen, PhD Adjunct Professor of Nutritional Epidemiology University of Eastern Finland Institute of Public Health and Clinical Nutrition Kuopio, FinlandMedicalResearch.com Interview with: Jyrki Virtanen, PhD Adjunct Professor of Nutritional Epidemiology University of Eastern Finland Institute of Public Health and Clinical Nutrition Kuopio, FinlandMedicalResearch.com: What are the main findings of the study?Dr. Virtanen: The main finding was that serum long-chain omega-3 polyunsaturated fatty acid (PUFA) concentration, an objective biomarker of fish and long-chain omega-3 PUFA intake, was associated with a lower risk of incident type 2 diabetes during the average follow-up of 19.3 years in middle-aged and older men from Eastern Finland. The risk was 33% lower in the highest vs. the lowest quartile after adjustment for potential confounders. In contrast, hair mercury, a marker for long-term exposure to mercury, was not associated with the risk. Previously in this study population, high hair mercury content has been associated with higher risk of cardiovascular diseases and attenuation of the beneficial impact of long-chain omega-3 PUFA on the risk. Also, we did not find associations with the intermediate-chain length omega-3 PUFA alpha-linolenic acid, either, which is a plant-based omega-3 PUFA. This suggests that the findings were specific to the long-chain omega-3 PUFAs from fish.(more…)

MedicalResearch.com Interview with Eric S. Weintraub, M.P.H. Epidemiologist at Centers for Disease Control and PreventionMedicalResearch.com: What are the main findings of the study?Mr. Weintraub: While current rotavirus vaccines were not associated with intussusception in large pre-licensure trials, recent post-licensure data (from international settings) suggest the possibility of a low risk of intussusception occurrence after receipt of monovalent rotavirus vaccination (RV1). We examined the risk of intussusception following RV1 vaccination in a U.S. population. In this study of more than 200,000 doses of RV1, a slight increased risk of intussusception was observed after vaccination, which should be considered in light of the benefits of preventing rotavirus associated illness.

MedicalResearch.com Interview with: Birgitta Ejdervik Lindblad, MD PhD Department of Ophthalmology Örebro University Hospital Örebro, SwedenMedicalResearch.com: What are the main findings of the study?Answer: We have investigated the association between smoking cessation and risk of having a cataract extraction among 44 371 Swedish men aged 45-79 years. During 12 years of follow up we identified 5713 incident cases of cataract extraction.Smoking cessation significantly decreased the risk with time.Men who currently smoked more than 15 cigarettes per day had a 42 % increased risk of cataract extraction compared with men who had never smoked. More than 20 years since quitting smoking, men who had smoked more than 15 cigarettes per day had a 21% increased risk of having a cataract extraction compared with men who had never smoked.The effect of smoking cessation was observed earlier among men who smoked less than 15 cigarettes per day but more than 2 decades since smoking cessation the risk had not decreased to the level of never smokers.

Terry-McElrath, MSA Institute for Social Research, University of Michigan, Ann ArborMedicalResearch.com: What are the main findings of the study?Answer: This study examined 2007-2012 commercialism trends in schools attended by nationally representative samples of US elementary and secondary students.While some measures showed significant decreases over time (especially beverage vending measures), most students at both elementary and secondary school levels continued to be exposed to school-based commercialism. Commercialism increased significantly with grade level. The most frequent type of commercialism varied by school level: food coupons used as incentives was most common at the elementary school level, while exclusive beverage contracts were the most prevalent type of commercialism for middle and high school students.

David M. Albala, MD Associated Medical Professionals of NY, PLLC Syracuse, NY 13210MedicalResearch.com Interview with:David M. Albala, MD Associated Medical Professionals of NY, PLLC Syracuse, NY 13210MedicalResearch.com: What are the main findings of the study?Dr. Albala: Prostate cancer is the second leading cause of cancer death and American man. Prostate cancer diagnosis and mortality differences between African American and Caucasian populations have been highlighted in the literature. Research has shown that African American males are at a biological predisposition for prostate cancer and that additional socioeconomic and physician-patient educational factors may contribute to a higher mortality rate among this group - over two times greater than that of Caucasian American males.At present the most commonly used to detection tools for prostate cancer are the serum prostatic specific antigen test (PSA) and a digital rectal examination (DRE). These complementary tests provide physicians with an indication of whether to proceed with biopsy for a definitive pathological diagnosis. Despite ongoing disputes regarding the effectiveness of PSA screening as an indicator for prostate cancer, a superior alternative test as yet to become available for men at risk.The American Urological Association (AUA) emphasizes the value of early detection and that sheared decision-making should not be overlooked and that shared decision making should be integral to screening decisions. The AUA urges individuals to personally assess, with their physicians, whether a PSA screen is necessary. Emphasis should be placed on the proper education of African American men who are at increased risk for the disease, as well as on their participation in repeated screening practices for the earliest possible detection of prostate cancer.

We wanted to measure the point at which the risk of cancer outweighed the burden and inconvenience of testing in relation to lung, colorectal and pancreas cancers. Most people, around 88%, opted for testing even at the lowest risk of cancer which in our vignettes was 1%. Further analyses showed variation between cancers with fewer people opting for testing for colorectal cancer at a low (1%) risk and more people choosing to be tested for all cancers in the 60-69 age group.

MedicalResearch.com Interview with: Anna-Christina Lauer, MD Department of Audiology and Phoniatrics Charité-University Medicine Berlin Berlin, GermanyMedicalResearch.com: What are the main findings of the study?Dr. Gross: We could show that the injury rates depend on the undergraduate medical training the students attended. This demonstrates that medical undergraduatue education, especially a hands-on training, is critical in the prevention of needlestick- and sharps injuries.Also the use of safety devices has proven to reduce injury rates significantly.Given the large size of our study we could not only comfirm that needlestick and sharps injuries are still a common problem, looking at an injury rate of about 20% per year, we also learned a lot about the accident circumstances: Most accidents occur at bedside during venepuncture and intravenous cannulation. The second most common setting is the operating room, where suturing and instrument transfers can lead to injuries.Since we analyzed official reports and the anonymous surveys at the same time we could affirm an underreporting rate of more than 50%.

Naama Barnea-Goraly M.D. Center for Interdisciplinary Brain Sciences Research Stanford UniversityMedicalResearch.com Interview with:Naama Barnea-Goraly M.D. Center for Interdisciplinary Brain Sciences Research Stanford UniversityMedicalResearch.com: What are the main findings of the study?Answer: Our main findings showed that compared with age and sex matched controls, children with type 1 diabetes have significant differences in white matter structure in widespread brain regions. Within the type 1 diabetes group, earlier onset of diabetes and longer duration were associated with greater alterations in white matter structure. In addition, measures of hyperglycemia and glucose variability, but not hypoglycemia were associated with white matter structure; however, hypoglycemia exposure and the number of severe hypoglycemia events in our sample were too small to identify statistically meaningful differences. Finally, we observed a significant association between white matter structure and cognitive ability in children with type 1 diabetes, but not in controls.(more…)

Rudin, Ph.D. Associate Policy Researcher RAND Corporation Boston, MA 02116MedicalResearch.com: What are the main findings of the study?Dr. Rudin:We found that most published health IT implementation studies report positive effects on quality, safety, and efficiency. Most evaluations focus on clinical decision support and computerized provider order entry. However, not all studies report equally positive results, and differences in context and implementation are one likely reason for these varying results, yet details of context and implementation are rarely reported in these studies.

Maurice Dysken, MD Professor, School of Medicine Department of Psychiatry Minneapolis VA Health Care System, Minneapolis, MinnesotaMedicalResearch.com Interview InvitationMaurice Dysken, MD Professor, School of Medicine Department of Psychiatry Minneapolis VA Health Care System, Minneapolis, MinnesotaMedicalResearch.com: What are the main findings of the study?Dr. Dysken: In patients with mild-to-moderate Alzheimer’s disease who were taking an acetylcholinesterase inhibitor, a dosage of 2000 IU/d of vitamin E significantly slowed functional decline compared to placebo by 6.2 months over the mean follow-up period of 2.27 years. Over this period of time caregiver time increased least in the vitamin E group compared to the other three groups (memantine alone, vitamin E plus memantine, and placebo) although the only statistically significant difference was between vitamin E alone and memantine alone. There were no significant safety concerns for vitamin E compared to placebo and mortality was lowest in the vitamin E alone group. It should be noted that patients who were on warfarin were excluded from the study because of a possible interaction with vitamin E that could have possibly increased bleeding events. (more…)

In our study, we found that a long-term adherence to a high-quality dietary pattern akin to the traditional MedDiet and rich in extra-virgin olive oil was able to reduce the incidence of new cases of diabetes in older individuals at high cardiovascular risk. We have demonstrated for the first time that a beneficial effect on diabetes prevention could be obtained witha healthy dietary pattern (without calorie restriction, increased physical activity or weight loss). These benefits have been observed in participants between 55 to 80 years-old at high cardiovascular risk; therefore,the message is that it is never too late to switch to a healthy diet like the Mediterranean.

This is the first study focusing upon the carriage of viable C. difficile spores on healthcare workers’ hands. C. difficile exist in 2 possible forms: vegetative and spore. Vegetative forms of C. difficile are killed when exposed to air, whereas their spores are resistant to oxygen, desiccation, and most disinfectants, and may persist in the hospital environment for long periods of time; thus, bacterial spores could be the principal form of transmission. Furthermore, contamination of exposed healthcare workers’ hands is statistically associated with direct exposure to fecal soiling and contact without the use of gloves.(more…)

Dr. James Sheppard MRC Research Fellow Department of Primary Care Health Sciences University of OxfordMedicalResearch.com Interview withDr. James Sheppard MRC Research Fellow Department of Primary Care Health Sciences University of OxfordMedicalResearch.com: What are the main findings of the study?Dr. Sheppard: The aim of our study was to develop a decision-tree model which estimates the cost-effectiveness and potential implementation costs of a series of interventions which increase thrombolysis rates in acute stroke. The model examined all possible acute stroke patient pathways and was based on real life patient data. We found all proposed interventions to be cost saving whilst increasing patient quality of life after stroke. We estimate that, assuming a "willingness-to-pay" of USD $30,000 per quality adjusted life year gained, the potential budget available to deliver interventions which improve acute stroke care range from USD $50,000 to USD $144,000.

Madhav Goyal MD, MPH Assistant Professor General Internal Medicine Johns Hopkins School of MedicineMedicalResearch.com Interview with:Madhav Goyal MD, MPH Assistant Professor General Internal Medicine Johns Hopkins School of MedicineMedicalResearch.com: What are the main findings of the study?Dr. Goyal:
  • The evidence is moderately strong that there is a small but consistent benefit for mindfulness meditation programs to improve 3 symptoms: anxiety, depression, and pain. We found low level evidence that mindfulness meditation helps with symptoms of stress and distress, as well as with the mental health dimension of quality of life.
  • For the symptoms of anxiety and depression for which we find moderate evidence of benefit, we need to keep in mind that most of the trials didn't study people with a clinical diagnosis of anxiety or depression (although a few did). Most were studying diverse patient populations who may have had a low level of these symptoms, such as those with breast cancer, fibromyalgia, organ transplant recipients, and caregivers of people with dementia.
  • We found about a 5-10% improvement in anxiety symptoms compared to placebo groups. For depression, we found a roughly 10-20% improvement in depressive symptoms compared to the placebo groups. This is similar to the effects that other studies have found for the use of antidepressants in similar populations.
  • While we found that the evidence was moderately strong that mindfulness meditation programs may improve pain, there weren't as many trials evaluating chronic pain, and so we don't understand what kinds of pain this type of meditation may be most useful for.

Dr. Lisa Croen, PhD Senior Research Scientist Director, Autism Research Program Division of Research Kaiser Permanente Northern CaliforniaMedicalResearch.com Interview withDr. Lisa Croen, PhD Senior Research Scientist Director, Autism Research Program Division of Research Kaiser Permanente Northern CaliforniaMedicalResearch.com: What are the main findings of the study?Dr. Croen: Researchers found that hospital-diagnosed maternal bacterial infections during pregnancy were associated with an increased risk of autism spectrum disorders (ASD) in children. While infections are fairly common in pregnant women, this study only found increased risks in cases of bacterial infections. Women with bacterial infections diagnosed during a hospitalization (including of the genitals, urinary tract and amniotic fluid) had a 58 percent greater risk of having a child with ASD.Also of note, bacterial infections diagnosed during a hospitalization in the second trimester, while not very common in any of the mothers studied, were associated with children having more than a three-fold increased risk of developing ASD.These findings resulted from a study of 407 children with autism and 2,075 matched children who did not have autism. The study included infants born between January 1995 and June 1999 who remained members of the Kaiser Permanente health plan for at least two years following birth. (more…)

Meehan III, MD Director, Micheli Center for Sports Injury Prevention Director, Sports Concussion Clinic, Boston Children?s Hospital Waltham, MA 02453MedicalResearch.com: What are the main findings of this study?Dr. Meehan: The study has 2 findings that I believe are the most worthy of attention. First, although cognitive rest has been recommended as a therapy for concussion for several years now, there has been little data showing its effect. This lack of data has led to variability in the recommendations for cognitive rest, with some experts not recommending it all, and others recommending athletes avoid all cognitive activity, lying alone in a dark room even, until they are completely recovered. As you can imaging, this has generated controversy. We believe this is the first study showing the independent, beneficial effect of limiting cognitive activity on recovery from concussion. (more…)

Jonathan Cedernaes PhD Department of Neuroscience Uppsala University SwedenMedicalResearch.com Interview with:Jonathan Cedernaes PhD Department of Neuroscience Uppsala University Sweden MedicalResearch.com: What are the main findings of this study?Dr. Cedernaes: We found that two peripheral blood markers were modestly but significantly increased in healthy young participants after a single night of sleep deprivation, as compared with a normal night of sleep. These two markers, S-100B and NSE, are for example used as markers of acute ischemic injury in the brain, and are also increased following concussions. S-100B is produced mainly by glial cells and also increases after injury to the blood brain barrier. NSE is instead produced by neurons and is regarded as being more specific for neuronal damage, although it can also be produced by peripheral cells. (more…)

Prof Sirpa Jalkanen MD, PhD MediCity Research Laboratory and Department of Medical Microbiology University of Turku Turku, FinlandMedicalResearch.com Interview with:Prof Sirpa Jalkanen MD, PhD MediCity Research Laboratory and Department of Medical Microbiology University of Turku Turku, FinlandMedicalResearch.com: What are the main findings of the study?Answer:Pulmonary vascular leakage occurs early in acute lung injury/acute respiratory distress syndrome (ALI/ARDS). Mortality is high (35-45%), but no effective pharmacotherapy exists. Production of anti-inflammatory adenosine by ecto-5’-nucleotidase (CD73) maintains endothelial barrier function. Interferon-beta-1a (IFN-beta) increases CD73 synthesis and might thus reduce vascular leakage and mortality in ALI/ARDS. We tested this hypothesis and the findings were as follows:1.IFN-beta increased the number of CD73-positive vessels in human lung culture (4- and 14.3-fold on days 1 and 4 respectively, p=0.04 and 0.004).2. The optimal tolerated FP-1201 dose (a unique intravenous formulation of interferon-beta 10 μg /day for six days) caused a significant rise in serum MxA (a marker for interferon response) and CD73 levels and a fall in interleukin-6 (an inflammatory cytokine) concentration.3. Most importantly, odds of 28-day mortality was 81% lower in the treated than untreated subjects (8% vs 32%, OR[95% CI]0.19[0.03 to 0.72], p=0.01).(more…)
