To evaluate the effects on depressive mood of withdrawal of antihypertensive medication, we conducted a randomized, multi-center study with clinical centers at the Albert Einstein College of Medicine, Bronx, NY, University of Alabama School of Medicine, Birmingham, and the University of Mississippi School of Medicine in Jackson. Patients were formerly active participants in the Hypertension Detection and Follow-Up Program (HDFP) whose blood pressure was controlled with drugs for a period of 5 years. Of 496 patients, 431 had both baseline and "1-year" mood scores. Patients, stratified by obesity, were randomized to one of three groups: continue the HDFP medication; discontinue medication with no dietary intervention, or with sodium restriction and potassium increase; or, for those overweight, to a weight reduction intervention. Depression was assessed using the CES-D scale (Center for Epidemiological Studies--Depressed Mood), administered at baseline and again approximately 1 year after randomization. Of the seven treatment groups, only those who continued their HDFP medication showed significant improvement in mood from baseline. The overweight continue-medication group showed significantly greater improvement compared to the no-drugs, no-diet intervention groups, and to the overweight sodium-restriction group. Patients who had their blood pressure successfully controlled with weight reduction had a significant improvement in mood from 11.0 scale points to 8.0, P = .006. Comparisons between those withdrawn from diuretic alone and those withdrawn from both diuretic plus reserpine were inconclusive. Dietary Intervention Study of Hypertension (DISH) shows no evidence that continued use of chlorthalidone has a negative impact on quality of life, while our results concerning reserpine were inconclusive.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical risk prediction is important in the prognostication of peri-operative cardiac complications and the management of high-risk cardiac patients for major non-cardiac surgery. However, the current pre-operative clinical risk indices have been derived in European and American patients and not validated in South African patients. The purpose of this study was to evaluate the utility of the clinical risk predictors identified in Lee's revised cardiac risk index and in the African arm of the INTERHEART study, in predicting cardiac mortality following vascular surgery in South African patients. A retrospective cohort study was conducted of all patients undergoing elective or urgent vascular surgery at Inkosi Albert Luthuli Central Hospital over a three-year period. All in-hospital deaths were identified and classified into cardiac or non-cardiac deaths by an investigator blinded to the patients' pre-operative clinical risk predicators. A second investigator blinded to the cause of death identified the following clinical risk predictors: history of ischaemic heart disease, congestive cardiac failure and cerebrovascular accident, presence of diabetes, hypertension and obesity (BMI > 30 kg.m(-2)), elevated serum creatinine (> 180 micromol.l(-1)), positive smoking history and ethnicity. The main finding was that a serum creatinine level of greater than 180 micromol.l(-1) and a positive smoking history were significantly associated with cardiac death (p = 0.012, p = 0.012, respectively). Multivariate analyses using a backward stepwise modeling technique found only a serum creatinine of > 180 micromol.l(-1) and a positive smoking history to be significantly associated with cardiac mortality (p = 0.038, 0.035, respectively) with an odds ratio and 95% confidence interval of 3.02 (1.06-8.59) and 3.40 (1.09-10.62), respectively. All other clinical predictors were not significantly different between the two groups. However, based on the sample size of this study, a type 2 or b error may have resulted in the other risk predictors not being identified as important clinical predictors of cardiac mortality. Therefore, until such time as a study of adequate power is conducted, a history of ischaemic heart disease, congestive cardiac failure, diabetes and cerebrovascular accidents should still be considered to be important clinical risk predictors in South African surgical patients. In conclusion, an elevated serum creatinine and a positive history for smoking are important clinical predictors of cardiac mortality in South African patients following elective or urgent vascular surgery.

Certain beverages contribute energy, protein, vitamins, and minerals. North American adolescents have shifted their beverage intake from predominantly milk to predominantly sugary beverages. Intake of these sugary beverages, in sufficient quantity, may increase the risk of bone fractures, may contribute to obesity, and may lead to tooth decay. This study evaluated the effectiveness of a school-nutrition education program (Fluids Used Effectively for Living) on nutrition knowledge, attitude, and self-reported behavior of grade 9 students in Saskatchewan, Canada. Two classes of grade 9 students, 1 (n = 33) in a high school in Saskatoon (n = 33) and 1 (n = 24) in a large high school in Prince Albert, Saskatchewan, received the peer educator intervention. Two other classes in the 2 cities (n = 24 and n = 24, respectively) were controls. Six sessions of Fluids Used Effectively for Living nutrition education were delivered by using 2 peer educator models (multiple and single), and the intervention was delivered in a 45-minute weekly class session over a 6-week period. After the intervention, students in these 2 peer educator classes decreased their sugary beverage intake significantly, which was sustained for 3 months. Students in the control self-taught class increased their juice intake at the end of the year. The significant decrease of juice and sugary beverage intakes in the single model peer educator class disappeared after Bonferroni correction. Carbonated sugary beverage intake of students in the control self-taught classes declined, but it was not sustainable at the 3-month follow-up. A peer educator school-based nutrition education approach can lead to a decrease in sugary beverage intake in high school children.

Relationship between adipose tissue and fatty liver, and its possible evolution in fibrosis, is supported by clinical and research experience. Given the multifactorial pathogenesis of non-alcoholic fatty liver disease (NAFLD), treatments for various contributory risk factors have been proposed; however, there is no single validated therapy or drug association recommended for all cases which can stand alone. Mechanisms, diagnostics, prevention and treatment of obesity, fatty liver and insulin resistance are displayed along with recommendations and position points. Evidences and practice can get sustainable and cost-benefit valuable outcomes by participatory interventions. These recommendations can be enhanced by comprehensive research projects, addressed to societal issues and innovation, market appeal and industry development, cultural acceptance and sustainability. The basis of participatory medicine is a greater widespread awareness of a condition which is both a disease and an easy documented and inclusive clue for associated diseases and unhealthy lifestyle. This model is suitable for addressing prevention and useful for monitoring improvement, worsening and adherence with non-invasive imaging tools which allow targeted approaches. The latter include health psychology and nutritional and physical exercise prescription expertise disseminated by continuous medical education but, more important, by concrete curricula for training undergraduate and postgraduate students. It is possible and recommended to do it by early formal teaching of ultrasound imaging procedures and of practical lifestyle intervention strategies, including approaches aimed to healthier fashion suggestions. Guidelines and requirements of research project funding calls should be addressed also to NAFLD and allied conditions and should encompass the goal of training by research and the inclusion of participatory medicine topics. A deeper awareness of ethics of competences in health professionals and the articulation of knowledge, expertise and skills of medical doctors, dieticians, health psychologists and sport and physical exercise graduates are the necessary strategy for detectin a suboptimal health status and achieving realistically beneficial lifestyle changes. "The devil has put a penalty on all things we enjoy in life. Either we suffer in health or we suffer in soul or we get fat" (Albert Einstein); the task of medical research and intervention is to make possible to enjoy life also without things that make sufferance in health and souls and which excessively increase body fat.

Albert J. Stunkard, MD, was an internationally recognized leader and pioneer in the field of obesity and eating disorders research. He was also among the first scientists to study eating phenotypes and early life risk factors for childhood obesity at a time when childhood obesity prevalence rates were still comparatively low. The aim of this review is to highlight select findings from the work of Albert J. Stunkard which significantly advanced our understanding of eating traits of children with a different familial predisposition to obesity and genetic and environmental influences on weight outcomes. Collectively, Stunkard's early work on childhood obesity had a significant impact on the field of ingestive behavior and obesity research in that he was one of the first investigators who pointed to genetic influences underlying behavioral eating traits and child weight status. His work also inspired numerous subsequent investigations on the relative contributions of specific genes (e.g., polymorphisms in the fat mass and obesity-associated (FTO) gene) on individual differences in child eating traits (e.g., satiety responsiveness, eating in the absence of hunger) and body weight.
