MedicalResearch.com Interview with: Prof. Michael d’Emden Endocrine Research Unit Royal Brisbane Hospital, Brisbane, Australia Medical Research: What are the main findings of the study? Prof. d’Emden: Our study is the largest trial of women having type 2 diabetes assessing the role of a fibric acid derivative, in this case fenofibrate, ever conducted.  There were 3657 female subjects randomized to placebo or fenofibrate.  The study demonstrated greater reductions in women of total cholesterol, triglycerides and LDL-cholesterol and greater increases in HDL-cholesterol.  In women, fenofibrate decreased total cardiovascular end-points by 30% compared with only 13% in men, although there was no-treatment-by-sex interaction.  The majority of end points assessed revealed a consistent trend to increased benefit being seen in women.

Dr. Thorat : Accumulating evidence supports an effect of aspirin in reducing cancer incidence and mortality. Our analyses show that for average-risk individuals aged 50-65y taking aspirin for 10 years, there would be a relative reduction of between 7% (women) and 9% (men) in the number of cancer, myocardial infarction or stroke events over a 15 year period and an overall 4% relative reduction in all deaths over a 20 year period. The benefits of aspirin use would be most visible in the reduction in deaths due to cancer. If the findings of our study are applied to the UK general population aged 50-64 taking aspirin for next 10 years, on an average more than 6000 lives will be saved every year. (more…)

Frank van Hees, MSc Researcher, Department of Public Health, Erasmus MC Rotterdam, The NetherlandsMedicalResearch.com Interview with: Frank van Hees MSc Erasmus University Medical Center Rotterdam, the Netherlands   Medical Research: What are the main findings of the study? Answer: Many U.S. elderly are screened for colorectal cancer more frequently than recommended: One in every five elderly with a negative screening colonoscopy result undergoes another screening colonoscopy within 5 years’ time instead of after the recommended 10 years. Moreover, one in every four elderly with a negative screening colonoscopy result at age 75 or older receives yet another screening colonoscopy at an even more advanced age. Our study shows that, in average risk individuals, these practices are not only a waste of scarce health care resources: often they are also associated with a balance among benefits, burden, and harms that is unfavorable for those being screened.

MedicalResearch.com Interview with: Sylvie S.L. Leung Yinko, RD MSc Epidemiology '14 Division of Clinical Epidemiology Research Institute of McGill University Health Centre (RI MUHC) Montreal (QC) H3A 1A1 Medical Research: What are the main findings of the study? Answer: Our study indicates that young female patients with premature acute coronary syndrome (ACS) have lower health-related quality of life (HRQL) than their male counterparts. Whereas “sex” refers to whether an individual is biologically male or female, “gender” is a more complex term that refers to social norms, roles, and expectations that are traditionally ascribed to males and females in a society. We found that gender, rather than sex, may larger explain the differences in health-related quality of life between men and women. Particularly, higher femininity score, lower social support and greater housework responsibilities appear to be important gender-related factors linked with poorer HRQL post-ACS. (more…)

Dr. Sarkar: Retinoic acid (Vitamin A) is an anti-cancer drug for a number of cancers including liver cancer. However, all patients do not respond to retinoic acid. Astrocyte elevated gene-1 (AEG-1) is overexpressed in a large percentage of cancer patients and promotes development and progression of cancer. In this study we document that AEG-1 inhibits retinoic acid function. Combinatorial strategy involving AEG-1 inhibition and retinoic acid synergistically blocks growth of human liver cancer cells in animal models. (more…)

Senior Lecturer in Statistical Epidemiology & National Institute for Health Research Postdoctoral Fellow London School of Hygiene and Tropical Medicine London WC1E 7HT Medical Research: What are the main findings of the study? Dr. Bhaskaran: Body mass index was associated with the majority of cancer types studied, and for 10 cancers, including some of the most common like colon cancer and postmenopausal breast cancer, higher body mass index was clearly associated with higher risk. The cancer type that was most strongly related to BMI was uterine cancer, the 4th most common cancer in women. For a woman of average height, each 2 stone (13kg) increase in weight increased risk by over 60%. Body mass index also had particularly large effects on risk of kidney and gallbladder cancers. In total, we estimated that over 12,000 cases of the 10 affected cancers may be caused each year by excess weight, and that if average body mass index in the population continues to increase, there may be several thousand more cases of these cancers each year as a result.

Dr. Dechartres: In this study, we aimed to compare treatment effect estimates obtained from the meta-analysis including all trials to several alternative strategies for analysis. These alternative strategies are:
  • 1) the single most precise trial;
  • 2) a meta-analysis including only the largest trials;
  • 3) a “limit meta-analysis” that is a type of meta-analysis model recently developed to take into account small-study-effect and
  • 4) a meta-analysis restricted to trials at low risk of biases.
Our results showed that estimation of treatment effect varies depending of the strategy used with a frequently larger treatment effect in the meta-analysis of all trials than in the single most precise trial, the meta-analysis restricted to the largest trials and the limit meta-analysis, especially in case of subjective outcomes.

MedicalResearch.com Interview with: Dr. Cicely Marston Senior Lecturer in Social Science Department of Public Health and Policy London School of Hygiene and Tropical Medicine London WC1H 9SH Medical Research: What are the main findings of the study? Dr. Marston: Young people talked to us about an oppressive environment where some men compete with each other to have anal sex with women, even if they expect women to find it painful. Women also reported they were repeatedly asked for anal sex by their male partners and on some accounts, women enjoy it websites like https://bitchtopia.com/true-sex-stories/ go into detail about how the women asked for anal sex but we have found this is largely the minority among those we spoke too. Their accounts also raise the real possibility of coercion for young women – who were sometimes put in situations where they are penetrated anally without their explicit consent. Young people often suggested that pain for women was inevitable, or that it was the woman’s fault, ideas that may make them less likely to change their practices to reduce pain. Some young people said they thought STIs were less of a problem for anal sex compared with vaginal sex. Some young men put their own desire to have anal sex ahead of the desires and needs of their partners. (more…)

Dr. Holme: In this population-based trial, we found that once-only flexible sigmoidoscopy screening in asymptomatic 50-64 year old individuals reduces colorectal cancer mortality by 27% and colorectal cancer incidence by 20% after 11 years of follow-up. We found that the incidence reduction is as great in 50-54 year old individuals as in 55-64 old individuals. Addition of a once-only fecal occult blood test to flexible sigmoidoscopy did not lead to a larger reduction in colorectal cancer incidence or mortality compared to flexible sigmoidoscopy screening alone.

Greenberg, M.D. Vice President, Scientific & Medical Affairs, and Chief Medical Officer Sanofi Pasteur US.   Medical Research: What are the main findings of the study? Dr. Greenberg: The New England Journal of Medicine published positive results from a randomized, double-blind, large-scale, multi-center efficacy trial, which found that Fluzone® High-Dose (Influenza Vaccine) was more efficacious in preventing influenza illness (“the flu”) in adults 65 years of age and older compared to standard-dose Fluzone vaccine. Fluzone High-Dose vaccine was found to be 24.2 percent (95% CI, 9.7 to 36.5) more effective in preventing influenza relative to standard-dose Fluzone vaccine for the primary endpoint (laboratory-confirmed influenza associated with typical clinical symptoms occurring at least 14 days post-vaccination caused by any viral type or subtype). In other words, investigators determined that participants in the Fluzone High-Dose vaccine group were less likely to get the flu than those in the standard-dose Fluzone vaccine group. The study safety data were consistent with previous Fluzone High-Dose vaccine studies. (more…)

Dr Golam Khandaker Clinical Lecturer, Department of Psychiatry University of Cambridge MedicalResearch.com Interview with Dr Golam Khandaker Clinical Lecturer, Department of Psychiatry University of Cambridge Medical Research: What are the main findings of the study? Dr. Khandaker: The study shows low grade systemic inflammation may have a role in the pathogenesis of depression and psychotic disorders. Low grade systemic inflammation may also be a common cause for chronic physical and psychiatric illnesses. The study shows that higher serum levels of the circulating inflammatory marker, interleukin 6 (IL-6), in childhood is associated with nearly two-fold increased risk of developing depression and psychotic disorder in young adulthood. This association persisted after taking into account effects of age, sex, social class, ethnicity, body mass index, maternal depression, and past psychological and behavioural problem in the participant. We studied a sample of 4,500 individuals from the Avon Longitudinal Study of Parents and Children birth cohort, taking blood samples at age 9 and following up at age 18, to see if they had experienced episodes of depression or . We excluded children with an infection at the time of blood test at age 9 years. (more…)

Dr. Airaksinen:  The main result of our study is that the risk of thromboembolic complications in general was low (0.7%). However the risk rose to a 3.7-fold level when the delay to cardioversion exceeded 12 hours. The time-dependent increase in the risk of thromboembolic complications was more pronounced in female patients.

Dr. Cheng: We've known for some time that smoking, high cholesterol, high blood pressure, diabetes, and obesity all contribute to a person’s risk of being at risk for heart disease. The goal of our study was to look back over the last two decades and see how we've been doing in reducing the impact of these major cardiovascular risk factors on the actual risk for developing heart and vascular disease. We found that, not surprisingly, we've been doing generally better over time at lowering the overall impact of some risk factors such as smoking and high cholesterol. On the other hand, the impact of hypertension and diabetes has been high and has remained high over time. (more…)

MedicalResearch.com Interview with: Dr Sylvie Mesrine, Gynecologist, MD Inserm, CESP Centre for Research in Epidemiology and Population Health, U1018, Nutrition, Hormones and Women's Health Team, Villejuif, France. Medical Research: What are the main findings of the study? Answer: We wanted to disentangle the effect of recent physical activity (within the previous four years) from the effect of past physical activity (5-9 years earlier) on postmenopausal breast cancer risk. Our most important finding was that recreational/transport physical activity (including walking, cycling and engaging in other sports), even of modest intensity, seemed to have a rapid impact on breast cancer risk: it was quite rapidly associated with a decrease in breast cancer risk, which was however attenuated when activity stops. To our knowledge, our study is the first to independently assess the association between breast cancer risk and recreational physical activity both 5 to 9 years earlier and within the previous 4 years. Furthermore, the association of recent recreational physical activity and breast cancer risk decrease was observed whatever the recent levels of gardening or do-it yourself activities. (more…)

Prof. Philippe Steg:
  • Due to increasing use of angiography and revascularization, as well as improved drug therapy, the prevalence of angina and ischemia has diminished.
  • Most of the events (Cardiovascular death or Myocardial Infarction) occur in patients without angina or ischemia. This is very novel and important and stresses the importance of proper secondary prevention over "testing". We cannot be reassured by having a negative test for angina and ischemia.
  • Additionally, angina appears associated with a consistently greater risk than ischemia alone (having both is worse), so we need to pay attention to angina as a dire prognostic marker.
  • Findings should be no different in the US.
  • Most studies of silent ischemia antedate the advent of modern effective therapies or used very liberal definitions for "silent ischemia". (see our discussion)

Response: With prospective data from the Black Women’s Health Study, we assessed vigorous exercise and walking in relation to incidence of invasive breast cancer . We found that the overall incidence of breast cancer was lower among women who exercised vigorously or walked briskly than among women who were sedentary. The reduction was most apparent among women who exercised at least 5 hours per week. The association of exercise with breast cancer risk did not differ by estrogen receptor status of the breast tumor, but further study is needed to firmly establish this. Sitting for long periods at work or watching television was not significantly associated with breast cancer incidence. (more…)

Medical Research: What are the main findings of the study? Professor O'Gorman: 1155 cues for food and beverages (BBC=450; RTE=705), were recorded over 82.5 hours; thus, on average one cue was recorded every 4.2 minutes. The total recorded time for food and beverage cues was 3.94 hours, equating to 4.8% of the total recording time, and averaging 13.2 seconds per cue. If these results are representative of all children’s television broadcast on RTE and BBC, then if your child watches 82.5 hours of television, your child will see 3.94 hours of food and beverages during this time. Unhealthy foods account for 47.5% of specified food cues, and sugar-sweetened beverages for 25% of specified beverage cues, with an average time of 13.8 s for healthy cues and 11.4 s for unhealthy cues (p=0.17). 88.2% of all food and beverage cues involved a major character and 95.3% involved a character ‘goodie’. Male characters were more common than female (45.3% vs 14.0%), adults more common than teens or children (46.3% vs 23.8% and 14.2%). Overweight characters were depicted in 4.7%. The most common ethnic group was white Caucasian (88.5%). The commonest motivating factor for consuming/depiction of food and beverage was celebratory/social (25.2%), followed by hunger/thirst (25.0%), reward (4.5%), health-related (2.2%) and punishment (1.2%). Motivating factors were positive (30.5%), negative (1.5%) and health-related (25.8%). Cue outcomes were positive (32.6%), negative (19.8%) and neutral (47.5%). (more…)

The half that went home was younger and had lower WBC counts, lower neutrophils and less people with elevated temperature than the patients immediately admitted. Of the half that went home, 31% returned at least once to the ED within 30 days and 20% were admitted to undergo urgent cholecystectomy after the return visit, 55% percent of those within 7 days of the initial ED visit. Patients who failed the elective treatment plan had similar WBC counts but were more likely to have an ASA >3, slightly higher creatinine and higher average maximum VAS pain score. Patients who were less than 40 years old or older than 60 years were more likely to fail the elective pathway.” (more…)

Dr. Caroline E Stephens PhD Department of Community Health Systems University of California, San FranciscoMedicalResearch.com Interview with: Dr. Caroline E Stephens PhD Department of Community Health Systems University of California, San Francisco Medical Research: What are the main findings of the study? Dr. Stephens: In our national random sample of nursing home residents, we found that mild cognitive impairment (CI) predicted higher rates of ED visits compared to no CI, but interestingly, ED visit rates decreased as severity of cognitive impairment increased.  However, after nursing home residents were evaluated in the ED, severity of CI was not significantly associated with higher odds of hospitalization. Another important finding was that the proportion of nursing home residents using feeding tubes more than tripled in advanced or end-stage dementia, from 9.9% to 33.8%.  Moreover, tube-fed nursing home residents had 73% higher rates of total ED visits, but once evaluated in the ED, they were no more likely to be hospitalized than those without feeding tubes.  This finding is particularly striking given the numerous existing studies that have questioned the utility and appropriateness of using feeding tubes in people with advanced dementia.

Dr. Malmgren: We found a significant shift to lower stage breast cancer at diagnosis with an observed increase in mammography detected breast cancer over time and a significant decrease in later stage cancers found by the patient or her doctor. Mammography detected breast cancers were more often treated with lumpectomy and radiation and less likely to require mastectomy or adjuvant chemotherapy. We also observed better 5 year invasive breast cancer specific survival among the mammography detected patients as opposed to the patient or physician detected breast cancer cases. (more…)
