To critically analyze appropriate clinical studies to assess the relationship between health conditions and the frequency of private prayer. Private prayer is defined as individuals praying for themselves.Using PubMed and other search engines, we identified over 300 articles reporting relationships between prayer and health conditions. We identified 41 observational clinical studies that evaluated the relationship between private prayer and health conditions. Prayer scores of 5 to 1 were assigned to studies, with 5 being private prayer for health and 1 being prayer in combination with meditation or Bible study. Frequency scores ranged from 3 to 1 with 3 being twice daily or more and 0 when frequency was not assessed. Studies were ranked from 8 to 1 based on the sum of Prayer and Frequency Scores.Twenty-one studies had Prayer-Frequency scores of 5 to 8, indicating that they evaluated private prayer (praying for one's own health) of suitable frequency in association with health conditions. Nine of 11 studies indicated that private prayer was associated with a significantly lower prevalence of depression (P value,0.01). Optimism as well as coping were significantly improved by prayer in four studies (P value, P 0.01). In 10 studies of mental health conditions-including anxiety and confusion-there was a significant benefit associated with prayer (P 0.01), In the reviewed studies, prayer did not have a significant effect on physical health or blood pressure.The reported observational studies suggest that frequent private prayer is associated with a significant benefit for depression, optimism, coping, and other mental health conditions such as anxiety. Controlled clinical trials are required to critically assess the associations of private prayer and health conditions.

Just as the type and duration of physical activity can have variable effects on the glucose levels and other cardiometabolic parameters among patients with type 2 diabetes mellitus (T2DM), so can the types of foods have variable effects as well. This 12-week randomized study of 51 study participants evaluated the impact of routine consumption of dark raisins versus alternative processed snacks on glucose levels and other cardiovascular risk factors among patients with type T2DM. In this study, compared to alternative processed snacks, those who consumed raisins had a significant 23% reduction in postprandial glucose levels (P = 0.024). Also compared to snacks, those who consumed raisins had a 19% reduction in fasting glucose and 0.12% reduction in hemoglobin A1c, although these latter findings did not achieve statistical significance. Regarding blood pressure, compared to alternative processed snacks, those who consumed raisins had a significant 8.7 mmHg reduction in systolic blood pressure (P = 0.035) (7.5% [P = 0.031]) but did not experience a significant reduction in diastolic blood pressure. Compared to alternative processed snacks, those who consumed raisins did not have a significant improvement in body weight, body mass index, waist circumference, fasting insulin, homeostatic model assessment of insulin resistance, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL), triglyceride, or non-HDL cholesterol levels. Overall, these data support raisins as a healthy alternative compare to processed snacks in patients with T2DM.

Health professionals are in need of more information about the weight-loss outcomes of using commercial weight-loss programs.A commercial behavioral intervention program using meal replacements, fruits, and vegetables (MR-FV) was compared with usual-care weight-loss counseling.Obese volunteers were randomly allocated to usual-care weight-loss counseling or participation in an MR-FV standardized behavioral education program. The MR-FV group attended weekly weight-loss classes for 16 weeks and weekly maintenance classes for 8 weeks.Obese women or men aged 20 to 65 years were recruited from the community through a commercial program provided at a university medical center.The control group (C group) received weight-management counseling from an experienced dietitian, while the intervention group (MR-FV group) participated in scheduled behavioral weight-loss classes. The MR-FV group participants were encouraged to consume 3 shakes, 2 entrées, and 5 servings of fruits or vegetables daily, and achieve physical activity goals (expend ≥ 8.4 mJ/week); they kept records and placed midweek phone calls. The C group was counseled at baseline, 8 weeks, and 16 weeks.Both groups were seen at baseline, and 8, 16, and 24 weeks for assessment of weight, risk factors, and side effects.The primary data analysis was intention to treat.Thirteen of 16 subjects (81.3%) in the C group and 18 of 22 subjects (81.8%) in the MR-FV group completed the 24-week study. Mean weight losses for the C group were: 1.3% (standard error [SE], 0.9) at 8 weeks; 0.7% (SE, 1.1) at 16 weeks; and 0.7% (SE, 1.1) or 0.7 kg at 24 weeks. Mean weight losses for the MR-FV group were: 8.5% (SE, 0.6) at 8 weeks, 12.5% (SE, 0.9) at 16 weeks, and 13.9% (SE, 1.1) or 13.7 kg at 24 weeks.A behavioral intervention with a low-energy diet including 5 meal replacements and 5 servings of fruits or vegetables enabled obese individuals to lose 13 kg more than control subjects over a 24-week period.

Many randomized controlled trials (RCTs) have assessed the effects of soy protein on serum lipoprotein risk factors for coronary heart disease (CHD). This review and meta-analysis assessed the quality of these RCTs and estimated the effects of soy protein consumption on serum lipoproteins.A comprehensive search using multiple databases was conducted for the years 1996 through 2008 to identify clinical trials related to soy protein intake and serum lipoprotein changes.RCTs were assessed that met these requirements: soy protein intake compared with nonsoy protein, provided information on serum low-density lipoprotein (LDL)-cholesterol values, provided no more than 65 g of soy protein daily, and obtained LDL-cholesterol measurements between 4 and 18 weeks of treatment. Randomized parallel and crossover studies were evaluated.Studies were graded for quality using 12 criteria with a possible maximum grade of 24. Net changes in lipoproteins with soy protein consumption compared with nonsoy control diets were analyzed by meta-analyses and funnel plots. Confidence intervals were constructed using inverse weighting. Analyses compared parallel to crossover studies and studies with lower and higher grades.Analyses included 20 parallel-design studies and 23 crossover studies. Parallel studies scored significantly higher (p0.001) in study quality, with a mean grade of 15.8 (95% confidence interval [CI], 14.3 to 17.3) compared with 10.1 (95% CI, 8.2 to 11.9) for crossover trials. Soy protein intake was associated with net changes in serum LDL-cholesterol values of -0.23 mmol/l (95% CI, -0.28 to -0.18 mmol/l) or a 5.5% reduction in parallel studies and -0.16 mmol/l (95% CI, -0.22 to -0.11 mmol/l) or a reduction of 4.2% with crossover studies (p0.001 for parallel vs crossover). In parallel studies, net serum HDL-cholesterol values were 3.2% higher (p0.007) with soy vs control, and fasting serum triacylglycerol values were 10.7% lower (p0.008) for soy vs control.Soy protein consumption with a median of 30 g/d was associated with a significant improvement in lipoprotein risk factors for CHD. Compared with crossover RCTs, parallel RCTs had significantly higher quality grades and were associated with significantly greater improvements in serum LDL-cholesterol values. Regular consumption of 1 to 2 servings of soy protein daily (15 to 30 g) has a significant favorable impact on serum lipoprotein risk factors for CHD.

Improved nutritional habits are a major target in the treatment of dyslipidemias and atherosclerosis prevention. A number of newer approaches have been developed in the last few years, leading to a better knowledge of nutrients as well as of novel functional foods, supplements or nutraceuticals, which may provide an alternative to lipid-lowering drugs. Functional foods are fortified or enriched products with potential health benefits, whereas nutraceuticals can be defined as diet supplements that deliver a presumed bioactive food component in a nonfood matrix. Specific areas of current interest are those of dietary proteins with specific effects on cholesterolemia, also leading to the identification of absorbable peptides and changes in fat intake, resulting in a larger consumption of monounsaturated fatty acids. Both approaches represent an improvement compared with the classical method based on a low-lipid intake. Relevant nutraceuticals include plant sterols/stanols for cholesterol reduction and polyph...

Soy protein intake has favorable effects on body weight and fat distribution in experimental animals but these effects have not been demonstrated in humans. To compare effects of soy- vs. milk-based meal replacements (MR) we assessed weight loss and serum lipoproteins changes for obese subjects who consumed low-energy diets (LED) including either milk-based or soy-based MR.Overweight or obese women and men (body mass indices 27-40 kg/m(2)) were randomly assigned to LED providing 1200 kcal/day, with consumption of five soy-based or two milk-based liquid MR for a 12-week weight loss trial. Serum lipoprotein measurements were obtained at baseline, 6 and 12 weeks.For soy and milk MR groups, subject numbers were, respectively, 51 and 39 randomized and 30 and 22 completers. MR use averaged: soy, 3.7/day; and milk, 1.9/day. Weight losses for completers at 12 weeks were: soy MR, 9.0% of initial body weight (95% confidence intervals, 7.3-10.6%); and milk MR, 7.9% (5.8-8.8%) with no significant differences. Reductions from baseline in serum cholesterol and LDL-cholesterol values, respectively, at six weeks were significantly greater (P0.015) with soy MR (15.2% and 17.4%) than with milk MR (7.9% and 7.7%). Soy MR use was associated with significant reductions in serum triglycerides at 6 and 12 weeks while milk MR use was not.Soy MR use, as part of a low-energy diet, was associated with slightly but not significantly greater weight loss over a 12-week period than milk MR use. These observations confirm previous studies documenting the effectiveness of MR use for weight loss.

To review international nutrition recommendations with a special emphasis on carbohydrate and fiber, analyze clinical trial information, and provide an evidence-based recommendation for medical nutrition therapy for individuals with diabetes. Relevant articles were identified by a thorough review of the literature and the data tabulated. Fixed-effects meta-analyses techniques were used to obtain mean estimates of changes in outcome measures in response to diet interventions. Most international organizations recommend that diabetic individuals achieve and maintain a desirable body weight with a body mass index of/=25 kg/m(2). For diabetic subjects moderate carbohydrate, high fiber diets compared to moderate carbohydrate, low fiber diets are associated with significantly lower values for: postprandial plasma glucose, total and low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides. High carbohydrate, high fiber diets compared to moderate carbohydrate, low fiber diets are associated with lower values for: fasting, postprandial and average plasma glucose; hemoglobin A(1c); total, LDL-cholesterol, HDL-cholesterol and triglycerides. Low glycemic index diets compared to high glycemic index diets are associated with lower fasting plasma glucose values and lower glycated protein values. Based on these analyses we recommend that the diabetic individual should be encouraged to achieve and maintain a desirable body weight and that the diet should provide these percentages of nutrients: carbohydrate,/=55%; protein, 12-16%; fat,30%; and monounsaturated fat, 12-15%. The diet should provide 25-50 g/day of dietary fiber (15-25 g/1000 kcal). Glycemic index information should be incorporated into exchanges and teaching material.

Obesity is a major risk factor for development of diabetes, and excessive energy intake is a major contributor to poor glycemic control in Type 2 diabetes. The impact of obesity on risk for diabetes as well as coronary heart disease (CHD) risk factors and the benefits of weight loss in decreasing risk for developing diabetes and improving glycemia and CHD risks were reviewed. A systematic review of the medical literature to assess the impact of obesity and weight gain on risk for diabetes and CHD was done. We performed a meta-analysis of the effects of weight loss for obese diabetic individuals. Controlled clinical trials assessing lifestyle changes on risk for developing diabetes and weight loss effects on glycemia and CHD risk factors were reviewed. Obesity and weight gain can increase risk for diabetes by greater than ninetyfold and CHD by about sixfold. Very-low-energy diets (VLED) decrease fasting plasma glucose values by approximately 50% within two weeks and these changes are sustained with continued energy restriction. Twelve weeks of energy-restricted diets were associated with these significant decreases: body weight, 9.6%; fasting plasma glucose, 25.7%; serum cholesterol, 9.2%; serum triglycerides, 26.7%; systolic blood pressure, 8.1%; and diastolic blood pressure, 8.6%. Larger weight losses were associated with larger reductions in these values. The reviewed data suggest that US health care providers should endorse the American Heart Association's and European diabetes associations' recommendations that diabetic persons achieve and maintain a BMI of

The main result here is the fact that the limit set of a geometrically finite Kleinian group with connected limit set is locally connected. For an analytically finite Kleinian group with connected limit set, we give necessary and sufficient conditions for the limit set to be locally connected.

The last decade has brought a tremendous turnaround in nutritional recommendations for diabetes management, moving from low-carbohydrate, high-fat diets to high-carbohydrate, high-fiber, low-fat diets. Clinical studies which furthered understanding of carbohydrate metabolism greatly contributed to the change. This paper reviews recent advances in selected aspects of carbohydrate nutrition and metabolism in diabetes mellitus.
