Abstract
BACKGROUND The prevalence of type 2 diabetes is currently high and still rising, predominantly in developing countries including Ghana. Type 2 diabetes patients' adherence to recommended diet is shown to improve their health outcomes. This study investigated dietary compliance and its determinants among type 2 diabetes patients in Tamale Metropolis, Ghana. METHODS This study employed analytical cross-sectional study design and involved 343 participants selected through systematic random sampling from the outpatient diabetes clinics of Tamale Teaching Hospital, Tamale West Hospital and Tamale Central Hospital. A semi-structured questionnaire was used to document participants' socio-demographic, lifestyle and clinical characteristics. The modified Morisky dietary adherence scale was used to assess dietary compliance. Bivariate and multivariate analyses were performed to determine the predictors of dietary compliance. RESULTS The mean age of participants was 56.4 ± 15.7 years. More than half of the participants (62.4%) were females. The participants had a higher compliance status (70.6%). The study also revealed that, as a patient's age increases, compliance decreases [Adjusted odd ratio (AOR): 0.96, 95%, Confidence interval (CI) 0.94-0.99, P = 0.002]. Regarding educational status, patients who completed JHS/Middle School [AOR: 2.458, 95% CI 1.019-5.928, P = 0.045] and SHS/Vocational School [AOR: 2.73, 95% CI 1.08-6.91, P = 0.035] were more likely to comply with dietary recommendations compared to those with no formal education. CONCLUSION The rate of dietary compliance was high among the study participants. Age and educational status of participants significantly influenced their dietary compliance, suggesting that these factors should be taken into account when developing strategies to enhance dietary adherence.

Abstract
BACKGROUND Lack of time is often cited by persons with type 2 diabetes for non-participation in regular exercise. This highlights the need to explores ways to help persons with type 2 diabetes to engage in an active lifestyle. This study evaluated the effect of a short duration norm intensity exercise on blood glucose and blood pressure in persons with type 2 diabetes. METHODS Twenty persons with type 2 diabetes were randomly assigned to either training group (n = 10) or control group (n = 10). The training group received 4-weeks ambulatory training on a motor-driven treadmill (2 x 20 min per week at 60% target heart rate). The control group received no training. Blood glucose, and systolic and diastolic blood pressures were assessed before and after the 4-weeks training. Repeated measures ANOVA were used to examine training effect. RESULTS Training significantly improved blood glucose (mean difference = -2.73; p = 0.03). No effects were found for systolic blood pressure (mean difference = -0.30; p = 0.96) and diastolic blood pressure (mean difference = -0.90; p = 0.82). CONCLUSION Training improved blood glucose but not blood pressure. A short-duration ambulatory training is an appropriate exercise mode to elicit beneficial effect, and exercise adoption in persons with type 2 diabetes. TRIAL REGISTRATION This pilot trial is registered with the Pan African Clinical Trial Registry at pactr.samrc.ac.za (PACTR202306601940612).

Abstract
Many eye diseases, such as diabetic retinopathy (DR), age-related macular degeneration (AMD), and cataracts are preventable and treatable with lifestyle. The objective of this review is to assess the most recent research on the ideal dietary approach to prevent or support the treatment of DR, AMD, and cataracts, as well as to construct a food pyramid that makes it simple for people who are at risk of developing these pathologies to decide what to eat. The food pyramid presented here proposes what should be consumed every day: 3 portions of low glycemic index (GI) grains (for fiber and zinc content), 5 portions (each portion: ≥200 g/day) of fruits and vegetables (spinach, broccoli, zucchini cooked, green leafy vegetables, orange, kiwi, grapefruit for folic acid, vitamin C, and lutein/zeaxanthin content, at least ≥42 μg/day, are to be preferred), extra virgin olive (EVO) oil (almost 20 mg/day for vitamin E and polyphenols content), nuts or oil seeds (20-30 g/day, for zinc content, at least ≥15.8 mg/day); weekly: fish (4 portions, for omega-3 content and eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA) 0.35-1.4 g/day), white meat (3 portions for vitamin B12 content), legumes (2 portions for vegetal proteins), eggs (2 portions for lutein/zeaxanthin content), light cheeses (2 portions for vitamin B6 content), and almost 3-4 times/week microgreen and spices (saffron and curcumin). At the top of the pyramid, there are two pennants: one green, which indicates the need for personalized supplementation (if daily requirements cannot be met through diet, omega-3, and L-methylfolate supplementation), and one red, which indicates that certain foods are prohibited (salt and sugar). Finally, 3-4 times per week, 30-40 min of aerobic and resistance exercises are required.

Abstract
Objective We investigated the effects of aerobic training on adipokine concentrations in women with polycystic ovary syndrome (PCOS). Subjects and methods 120 women, including 60 with PCOS and 60 without PCOS, were divided into six groups (n = 20) based on body fat percentages of 22%-27%, 28%-32%, and 33%-37%. All groups were submitted the same evaluations before and after 16 weeks of aerobic training. These included anthropometric and hemodynamic analyses, cardiopulmonary tests, and laboratory tests. Two-way analysis of variance was performed to evaluate the differences between women with and without PCOS, effect of the body fat percentage, and effect of aerobic training. Results Body fat and PCOS were associated with high values of blood glucose, insulin, and testosterone. Body fat also reduced adiponectin levels and increased leptin, tumor necrosis factoralpha (TNF-α), and interleukin-6 (IL-6). In contrast, the PCOS increased only TNF-α and IL-6 levels. In the PCOS group, aerobic training reduced insulin, triglycerides, leptin, and IL-6 levels. It also promoted an increase in adiponectin and high-density lipoprotein levels. However, aerobic training did not alter TNF-α concentrations. Conclusion The body fat potentiates metabolic impairments that may be harmful to women with PCOS. Aerobic training appears to promote an important beneficial effect on the metabolic regulation of adipokines, except TNF-α.

Abstract
Diabetes is a major social problem. As shown by epidemiological studies, the world incidence of diabetes is increasing and so is the number of people suffering from its complications. Therefore, it is important to determine possible preventive tools. In the prevention of diabetic retinopathy, it is essential to control glycemia, lipid profile and blood pressure. This can be done not only by pharmacological treatment, but first of all by promoting a healthy lifestyle, changing dietary habits and increasing physical activity. In our work, we present a review of the literature to show that physical exercise and an adequate diet can significantly reduce the risk of diabetes and diabetic retinopathy.

Abstract
PURPOSE OF REVIEW To summarize recent advancements in our understanding of the impact of dyslipidemia on microvascular complications in type 2 diabetes (T2D), with an emphasis on peripheral neuropathy and nephropathy. RECENT FINDINGS Mounting evidence suggests that rigorous glycemic control only mitigates certain microvascular complications in T2D patients. Particularly, well regulated blood glucose levels only marginally improve peripheral neuropathy in the T2D setting. Dyslipidemia, an abnormal lipid profile, is emerging as a key factor in peripheral neuropathy. Furthermore, although glycemic control may prevent or slow nephropathy, recent developments demonstrate that dyslipidemia can also affect kidney outcomes in normoglycemic patients. Transcriptomic, epigenomic, and lipidomic investigations, as well as integrative approaches, are shedding light on potential pathomechanisms. These molecular studies are identifying possible targets for therapeutic intervention. Complementing molecular research, lifestyle interventions are on-going to assess whether dietary choices and/or exercise, weight-loss, or surgical interventions, such as bariatric surgery, can ameliorate peripheral neuropathy and nephropathy in T2D patients. SUMMARY Dyslipidemia is an emerging mechanism in microvascular complications in T2D. Elucidating the molecular pathomechanisms may pinpoint potential lipid-centric treatments. Interventional studies of dietary changes, exercise, or weight-loss surgery may also positively impact these highly prevalent and morbid complications.

Abstract
BACKGROUND Nonadherence to lifestyle modification recommendations is a major challenge in the management of diabetes mellitus. This study was conducted to measure the prevalence and predictors of nonadherence to diet and physical activity recommendations among type 2 diabetes patients (T2D). METHODS A cross-sectional study involving 322 type 2 diabetes patients was conducted from April 1 to June 30, 2019. Data were collected through face-to-face interviews using structured and pretested questionnaire. Data on sociodemographic, psychosocial, and clinical characteristics were collected. Descriptive analytical results were reported in text, tables, and figures. Logistic regression was conducted to identify predictors of nonadherence to diet and physical activity. Variables with p value ≤0.25 in bivariate logistic regression were considered as candidates for multivariable regression. Multivariate logistic regression was performed to identify independent predictors. Odds ratios and their 95% confidence intervals together with p value ≤0.25 in bivariate logistic regression were considered as candidates for multivariable regression. Multivariate logistic regression was performed to identify independent predictors. Odds ratios and their 95% confidence intervals together with. RESULT The rate of nonadherence to physical activity and diet was 64.3% and 36%, respectively. Female gender (AOR: 2.6, 95% CI [1.52-4.56]), age > 60 years (AOR: 2.9, 95% CI [1.12-7.42]), being illiterate (AOR: 4.2, 95% CI [1.86-9.73]), diabetes duration of >5 years (AOR: 2.5, 95% CI [1.42-4.41]), and lack of social support (AOR: 2.4, 95% CI [1.42-4.35]) were independent predictors of nonadherence to physical activity recommendations. Factors associated with nonadherence to dietary recommendations were being male (AOR = 2.8, 95% CI: [1.35-5.65]), age > 60 years (AOR = 6.3, 95% CI: [2.21-18.17]), khat chewing (AOR = 8.0, 95% CI: [3.86-16.7]), lack of social support (AOR = 15.26, 95% CI = [7.45-32.8]), and doctor's instructions or advice regarding diet (AOR = 8.9, 95% CI = [4.26-18.9]). CONCLUSION The rate of nonadherence to diet and physical activity recommendations was high in the study area. Predictors of nonadherence to physical activity are female gender, age > 60 years, being illiterate, diabetes duration of >5 years, and lack of social support. Predictors of nonadherence to diet are being male, khat chewing, lack of social support, and doctor's instructions or advice regarding diet.

Abstract
AIMS Diabetic retinopathy (DR) is an important microvascular complication of diabetes mellitus (DM) and a leading cause of visual impairment and blindness among people of working age. Physical activity (PA) or exercise is critical and beneficial for DM patients, whereas studies evaluating the relationship between PA and DR have yielded inconsistent and inconclusive results. The American Diabetes Association's "Standards of Medical Care in Diabetes" has also pointed out the indeterminate roles of PA in DR prevention. The purpose of this systematic review and meta-analysis was to explore the association between PA and DR risk. METHODS Medline (accessed by PubMed), EmBase, and Cochrane Library were systematically searched for studies up to June 2018, and the reference lists of the published articles were searched manually. The association between PA and DR risk was assessed using random-effect meta-analysis. RESULTS Twenty-two studies were included in this meta-analysis. PA was found to have a protective association with DR [risk ratio (RR) = 0.94, 95% confidence interval (95% CI) 0.90-0.98, p = 0.005] in diabetic patients, and the impact was more pronounced on vision-threatening DR (RR = 0.89, 95% CI 0.80-0.98, p = 0.02). Sedentary behavior could increase the risk of DR (RR = 1.18, 95% CI 1.01-1.37, p = 0.04). Moderate-intensity PA was likely to have a slight protective effect (RR = 0.76, 95% CI 0.58-1.00, p = 0.05). CONCLUSION PA is associated with lower DR risk, and more studies should focus on the causality between them.

Abstract
Skipping breakfast or irregular breakfast is associated with poor glycemic control. However, a relationship between the timing of dinner and glycemic control in people with type 2 diabetes remains indefinite. Therefore, we investigated the relationship between late-night-dinner and glycemic control in people with type 2 diabetes. We performed questionnaire survey for lifestyle factors in this cross-sectional study. We defined having dinner later than eight pm as late-night-dinner. We examined the differences in clinical and metabolic parameters between those who have late-night-dinner and those who do not have. We also examined the relationship between late-night-dinner and HbA1c, using multiple regression analysis. Ninety-five people (23.2%) had a late-night-dinner, among 409 people with type 2 diabetes. Metabolic parameters (mean (SD) or median (interquartile range)) of people with late-night-dinner were worse than those of without, including body mass index (BMI) (24.4 (4.0) vs. 23.2 (3.4) kg/m2, p = 0.006), triglycerides (1.5 (1.1-2.1) vs. 1.2 (0.8-1.7) mmol/L, p < 0.001), HDL-cholesterol (1.4 (0.4) vs. 1.6 (0.4) mmol/L, p = 0.004) and hemoglobin A1c (58.1 (13.3) vs. 55.2 (10.2) mmol/mol, (7.5 (1.2) vs. 7.2 (0.9) %), p = 0.023)). Late-night-dinner (standardized regression coefficient = 0.13, p = 0.028) was associated with hemoglobin A1c after adjusting for age, BMI, sex, duration of diabetes, smoking, exercise, alcohol, snacking after dinner, nighttime sleep duration, time from dinner to bedtime, skipping breakfast, and medication for diabetes. Late-night-dinner is independently associated with poor glycemic control in people with type 2 diabetes.

Enhanced Oxidative Stress and Other Potential Biomarkers for Retinopathy in Type 2 Diabetics: Beneficial Effects of the Nutraceutic Supplements. BIOMED RESEARCH INTERNATIONAL 2015; 2015:408180. [PMID: 26618168 PMCID: PMC4649073 DOI: 10.1155/2015/408180] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/14/2015] [Revised: 08/28/2015] [Accepted: 08/31/2015] [Indexed: 12/28/2022]
Abstract
We have studied the global risk of retinopathy in a Mediterranean population of type 2 diabetes mellitus (T2DM) patients, according to clinical, biochemical, and lifestyle biomarkers. The effects of the oral supplementation containing antioxidants/omega 3 fatty acids (A/ω3) were also evaluated. Suitable participants were distributed into two main groups: (1) T2DMG (with retinopathy (+DR) or without retinopathy (-DR)) and (2) controls (CG). Participants were randomly assigned (+A/ω3) or not (-A/ω3) to the oral supplementation with a daily pill of Nutrof Omega (R) for 18 months. Data collected including demographics, anthropometrics, characteristics/lifestyle, ophthalmic examination (best corrected visual acuity, ocular fundus photographs, and retinal thickness as assessed by optical coherence tomography), and blood parameters (glucose, glycosylated hemoglobin, triglycerides, malondialdehyde, and total antioxidant capacity) were registered, integrated, and statistically processed by the SPSS 15.0 program. Finally, 208 participants (130 diabetics (68 +DR/62 -DR) and 78 controls) completed the follow-up. Blood analyses confirmed that the T2DMG+DR patients had significantly higher oxidative stress (p < 0.05), inflammatory (p < 0.05), and vascular (p < 0.001) risk markers than the T2DMG-DR and the CG. Furthermore, the A/ω3 oral supplementation positively changed the baseline parameters, presumptively by inducing metabolic activation and ameliorating the ocular health after 18 months of supplementation.

Abstract
Background Rhodiola rosea (Rhodiola) is a plant in the Crassulaceae family that grows in cold regions of the world. It is mainly used in clinics as an adaptogen. Recently, it has been mentioned that Rhodiola increases plasma β-endorphin to lower blood pressure. Thus, the present study aims to investigate the antidiabetic action of Rhodiola in relation to opioids in streptozotocin-induced diabetic rats (STZ-diabetic rats). Methods In the present study, the plasma glucose was analyzed with glucose oxidase method, and the determination of plasma β-endorphin was carried out using a commercially available enzyme-linked immunosorbent assay. The adrenalectomy of STZ-diabetic rats was used to evaluate the role of β-endorphin. In addition, quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and western blotting analysis were performed to investigate mRNA and protein expressions. Results Rhodiola-water extract dose-dependently lowered the plasma glucose in STZ-diabetic rats and this action was reversed by blockade of opioid μ-receptors using cyprodime. An increase of plasma β-endorphin by rhodiola-water extract was also observed in same manner. The plasma glucose lowering action of rhodiola-water extract was attenuated in bilateral adrenalectomized rats. In addition, continuous administration of rhodiola-water extract for 3 days in STZ-diabetic rats resulted in an increased expression of glucose transporter subtype 4 (GLUT 4) in skeletal muscle and a marked reduction of phosphoenolpyruvate carboxykinase (PEPCK) expression in liver. These effects were also reversed by blockade of opioid μ-receptors. Conclusions Taken together, rhodiola-water extract improves hyperglycemia via an increase of β-endorphin secretion from adrenal gland to activate opioid μ-receptors in STZ-diabetic rats.

Abstract
Omega-3 polyunsaturated fatty acids (n-3 PUFAs) enhance insulin sensitivity and glucose homeostasis in rodent models of insulin resistance. These beneficial effects have been linked with anti-inflammatory properties, but emerging data suggest that the mechanisms may also converge on mitochondria. We evaluated the influence of dietary n-3 PUFAs on mitochondrial physiology and muscle lipid metabolites in the context of high-fat diet (HFD) in mice. Mice were fed control diets (10% fat), HFD (60% fat), or HFD with fish oil (HFD+FO, 3.4% kcal from n-3 PUFAs) for 10 wk. Body mass and fat mass increased similarly in HFD and HFD+FO, but n-3 PUFAs attenuated the glucose intolerance that developed with HFD and increased expression of genes that regulate glucose metabolism in skeletal muscle. Despite similar muscle triglyceride levels in HFD and HFD+FO, long-chain acyl-CoAs and ceramides were lower in the presence of fish oil. Mitochondrial abundance and oxidative capacity were similarly increased in HFD and HFD+FO compared with controls. Hydrogen peroxide production was similarly elevated in HFD and HFD+FO in isolated mitochondria but not in permeabilized muscle fibers, likely due to increased activity and expression of catalase. These results support a hypothesis that n-3 PUFAs protect glucose tolerance, in part by preventing the accumulation of bioactive lipid mediators that interfere with insulin action. Furthermore, the respiratory function of skeletal muscle mitochondria does not appear to be a major factor in sphingolipid accumulation, glucose intolerance, or the protective effects of n-3 PUFAs.

Abstract
Volatile anaesthetics exert protective effects on the heart against perioperative ischaemic injury. However, there is growing evidence that these cardioprotective properties are reduced in case of type 2 diabetes mellitus. A strong predictor of postoperative cardiac function is myocardial substrate metabolism. In the type 2 diabetic heart, substrate metabolism is shifted from glucose utilisation to fatty acid oxidation, resulting in metabolic inflexibility and cardiac dysfunction. The ischaemic heart also loses its metabolic flexibility and can switch to glucose or fatty acid oxidation as its preferential state, which may deteriorate cardiac function even further in case of type 2 diabetes mellitus.Recent experimental studies suggest that the cardioprotective properties of volatile anaesthetics partly rely on changing myocardial substrate metabolism. Interventions that target at restoration of metabolic derangements, like lifestyle and pharmacological interventions, may therefore be an interesting candidate to reduce perioperative complications. This review will focus on the current knowledge regarding myocardial substrate metabolism during volatile anaesthesia in the obese and type 2 diabetic heart during perioperative ischaemia.

Abstract
OBJECTIVE: To investigate associations between physical activity, comorbidity severity, depressive symptoms, and health-related quality of life in type 2 diabetes mellitus. SUBJECTS AND METHODS: All individuals, 200 patients and 50 controls, aged from 40 to 60 years, were investigated by interview, and all variables were measured concurrently. Physical activity was evaluated by the International Physical Activity Questionnaire (IPAQ), Health-Related Quality of Life (HRQL) by the Short-Form Health Survey (SF-36), comorbidity severity by the Charlson Comorbidity Index (CCI), and depressive symptoms by the Beck Depression Inventory (BDI-II > 16). Single and multiple regression analysis evaluated the effects of independent variables on physical activity. RESULTS: The patients had more depressive symptoms and greater comorbidity severity (p < 0.005). Diabetic patients showed better activity levels (IPAQ) (p < 0.005). Functional Capacity, General State of Health, and Physical Limitation were the most affected subscales in the SF-36 evaluation of the HRQL. Sedentary diabetic patients had higher waist circumference, waist-to-hip ratios, more depressive symptoms, and worse HRQL. Functional capacity (p = 0.000), followed by General State of Health (p = 0.02), were the health status measure subscales independently associated with physical activity. Conclusions: The findings suggest that increasing patient independence and treating depressive symptoms can promote physical activity for type 2 diabetes mellitus patients. It is suggested that group activities and caregivers/family support might compensate for the patient dependence, and increase adherence to exercise programs in those that are less active.

Abstract
INTRODUCTION Sustainability of healthy lifestyle behaviours following participation in a research-based supervised lifestyle intervention programme is often poor. This study aimed to document factors reported by overweight and obese individuals with Type 2 diabetes as enhancing or impeding sustainability of lifestyle behaviours following participation in such a programme. METHODS Thirty patients who completed a 16-week research-based supervised lifestyle intervention programme, incorporating a structured energy restricted diet with or without supervised resistance-exercise training underwent a semi-structured qualitative interview about their experiences in maintaining programme components after 1 year. RESULTS Participants maintained 8.8 ± 8.9 kg of the 13.9 ± 6.6 kg weight loss achieved with the research-based supervised lifestyle intervention programme. Only 23% of participants indicated continuation of the complete diet programme. Desire for 'variety' (33%) and increased portion size (27%) were the most commonly reported reasons for discontinuation. Participants who undertook supervised exercise training during the programme indicated access to appropriate programmes/facilities (38%), more affordable gym membership (21%) and having a personal trainer/motivator (17%) would have facilitated exercise continuation. CONCLUSION In overweight and obese individuals with Type 2 diabetes, success of the research-based supervised lifestyle intervention programme was perceived as being primarily due to high levels of professional support and supervision, the discontinuation of which subsequently presented difficulties. The interview data provide insight into what people experience following the completion of a research-based intensive lifestyle intervention programme and suggest that programmes assembled for research purposes with the emphasis on compliance may not necessarily promote sustainable change.

Abstract
Background Type 2 diabetes is now a common and serious global health problem, which, for most countries, has evolved in association with rapid cultural and social changes, ageing populations, increasing urbanisation, dietary changes, reduced physical activity and other unhealthy lifestyle and behavioural patterns. Aims To identify the different approaches to physical training used in the last decade in the management of type 2 diabetes. Methods We searched PubMed and Science Direct for all randomised clinical trials from 1999 to 30 May 2010. Results We selected 17 randomised controlled trials, five studies with aerobic exercise, five with resistance exercise and seven combined exercise studies. Conclusions The use of resistance training for the treatment of type 2 diabetes is becoming more commonly used in the management of type 2 diabetes. The number of studies using resistance exercise has been growing over the last decade, and has actually become as widely used as the popular aerobic exercise. In turn, most of the reviewed studies have used interventions combining resistance and aerobic exercise. An exercise programme for diabetic patients should be seen as a form of treatment. Hence, there were no established guidelines for the duration of the programme, because exercise should become a habitual daily task, and assumed in a new lifestyle for long-term glucose control.

Abstract
An active lifestyle increases general health and is protects from a number of different conditions, including exercise and obesity. There is emerging evidence that exercise by itself exerts clinically beneficial effects in both lean and obese subjects, even in the absence of effects on weight.1 Recent results have brought an increasing understanding of the molecular mechanisms underlying the beneficial effects of exercise at the level of metabolism and changes in gene expression. There is a significant dose-response to the effect of exercise, and the current guidelines regarding exercise amount may need to be revised upwards. Furthermore, this treatment option should not be overlooked.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a common endocrine disorder, affecting 8-12% of women. Lifestyle modification, including increased physical activity, is the first-line approach in managing PCOS. A systematic review was performed to identify and describe the effect of exercise as an independent intervention on clinical outcomes in PCOS. METHODS Five databases were searched with no time limit. A pre-specified definition of PCOS was not used. Studies were included if exercise therapy (aerobic and/or resistance) could be evaluated as an independent treatment against a comparison group. Outcomes measured included cardiovascular risk factors [insulin resistance (IR), lipid profiles, blood pressure and weight] and reproductive measures (ovulation, menstrual regularity and fertility outcomes). Quality analysis was performed based on the Cochrane Handbook of Systematic Reviews and the Quality of Reporting of Meta-Analyses checklist. RESULTS Eight manuscripts were identified (five randomized controlled trials and three cohort studies). All studies involved moderate intensity physical activity and most were of either 12 or 24 weeks duration with frequency and duration of exercise sessions ranging between studies. The most consistent improvements included improved ovulation, reduced IR (9-30%) and weight loss (4.5-10%). Improvements were not dependant on the type of exercise, frequency or length of exercise sessions. CONCLUSIONS Exercise-specific interventions in PCOS are limited. Studies vary considerably in design, intensity and outcome measures; therefore conclusive results remain elusive. Larger, optimally designed studies are needed to both gain insights into the mechanisms of exercise action and to evaluate the public health impact of exercise of PCOS.

Abstract
Calorie restriction (CR) is defined as a reduction in calorie intake below the usual ad libitum intake without malnutrition. Ample of clinical and experimental evidence has demonstrated that CR is capable of retarding aging process and development of cardiovascular disease. Although suppression of reactive oxygen species production and inflammation plays a central role in the favorable cardiovascular effects of CR, the health benefit of CR is believed to be ultimately mediated through a cadre of biochemical and cellular adaptations including redox homeostasis, mitochondrial function, inflammation, apoptosis and autophagy. Despite the apparent beneficial cardiovascular effects of CR, implementation of CR in the health care management is still hampered by apparent applicability issues and health concerns. Here we briefly review the cardiac consequence of CR and discuss whether CR may represent a safe and effective strategy in the management of cardiovascular health.

Abstract
Insulin resistance (IR) is a consequence of obesity, and in women it is often inextricably linked with ovarian function leading to clinical reproductive manifestations such as early menarche onset, subfertility and polycystic ovary syndrome (PCOS). Likewise, the dramatic fall in oestrogen production after menopause may contribute to weight gain and changes in adipose tissue distribution. Overall, women who are obese, especially those with reproductive complications including PCOS, have been identified as specific high risk subgroups for further progression through to prediabetes, type 2 diabetes mellitus (T2DM) and potentially cardiovascular disease (CVD). This review focuses on the interrelationship between the ovarian function and obesity as well as its treatment strategies.

Abstract
OBJECTIVES Knowledge about the management status of diabetic mellitus (DM) is essential to improve diabetic management. Moreover, low income is associated with poor adherence to treatment and increased mortality. This study was performed to evaluate the management status of DM in low-income patients in a rural area. METHODS We enrolled 370 patients with type 2 DM living in Gokseong county, JeollaNamdo. A well-trained examiner measured the height, weight, waist circumference, blood pressure, total cholesterol, triglyceride, high density lipoprotein cholesterol, fasting blood sugar and glycosylated hemoglobin (HbA1c) levels. Carotid ultrasonography was used to measure carotid artery carotid artery intima media thickness (IMT) and plaque. ankle-brachial index (ABI) was used to evaluate peripheral artery disease. A fundoscopic examination was performed to evaluate diabetic retinopathy. A history of diabetes complications and health-related questionnaires were also completed. RESULTS The age of diabetic subjects was 68.7+/-8.7 years and the duration of diabetes was 8.9+/-8.2 years. Most (63.5%) had hypertension, and 45.7% had triglycerides below 150 mg/dl, 38.1% had low density lipoprotein cholesterol (LDL) cholesterol below 100 mg/dl, 48.7% had urine albumin to creatinine ratio (UACR) below 30 mg/g. Less than half (45.9%) achieved the goal of HbA1c less than 7% suggested by the American Diabetes Association (ADA). 10.6% had peripheral vascular disease, 11.9% had retinopathy, and 60.8% had chronic kidney disease. CONCLUSIONS DM management in low income patients is very poor and requires further work to improve.

Abstract
Cardiometabolic risk (CMR), also known as metabolic syndrome or insulin resistance syndrome, comprises obesity (particularly central or abdominal obesity), high triglycerides, low HDL, elevated blood pressure, and elevated plasma glucose. Leading to death from diabetes, heart disease, and stroke, the root cause of CMR is inadequate physical activity, a Western diet identified primarily by low intake of fruits, vegetables, and whole grains, and high in saturated fat, as well as a number of yet-to-be-identified genetic factors. While the pathophysiological pathways related to CMR are complex, the universal need for adequate physical activity and a diet that emphasizes fruits and vegetables and whole grains, while minimizing food high in added sugars and saturated fat suggests that these behaviors are the appropriate focus of intervention.

Abstract
The principal modifiable risk factors for stroke are hypertension, diabetes mellitus, hypercholesterolaemia, hyperhomocysteinaemia, smoking and limited physical activity. However, it is not clear whether physical inactivity is a risk factor per se, or because it predisposes to pathological conditions that are risk factors for stroke. The limited availability of effective therapeutic approaches for stroke emphasizes the crucial role of prevention of risk factors. The global burden associated with type 2 diabetes is large and continues to grow. Convincing epidemiologic data support the role of physical activity in preventing type 2 diabetes. The increasing evidence of physical activity in preventing diabetic complications, including stroke, has generated interest in the molecular basis underlying these beneficial effects. The aim of the present review is to discuss the biological mechanisms underlying the effect of physical activity in preventing stroke in type 2 diabetes.

Abstract
PURPOSE To test whether the prevalence of hypertension, hypercholesterolemia, and diabetes declines with marathon participation independent of annual running mileage. METHODS Cross-sectional associations of self-reported medication use in 62,284 male and 45,040 female participants of the National Runners' Health Study adjusted for age, diet, alcohol, and annual distance run. RESULTS By self-report, 31.7% of men and 29.1% of women ran 0.2 and 0.8 marathons per year, 8.6% of men and 4.4% of women ran between 1.0 and 1.8 marathons per year, and 3.8% of men and 1.5% of women ran an average of >or=2 marathons per year. The men's odds ratio per marathons per year run was 0.85 for antihypertensive (P < 0.0001), 0.87 for LDL-cholesterol-lowering (P = 0.002), and 0.52 for antidiabetic medication use (P < 0.0001). Compared with nonmarathoners, men who averaged 0.2-0.8 marathons per year had 13% lower odds for antihypertensive medication use, 22% lower odds for LDL-cholesterol-lowering medication use, and 67% lower odds for antidiabetic medication use. Marathon participation was also associated with lower LDL-cholesterol-lowering and antidiabetic medication use in women, but not when adjusted for annual distance run. Each additional hour required to complete their marathon had odds ratio of 1.31 and 1.22 for men's antihypertensive and LDL-cholesterol-lowering medication use and 2.01 for women's antidiabetic medication use (all P < 0.0001). Among all runners (marathoners and nonmarathoners combined), prevalence in the use of all three medications decreased in association with the length of the longest usual run, independent of total annual mileage. CONCLUSION Prevalence of hypertension, hypercholesterolemia, and diabetes decreases with the frequency of marathon participation independent of annual running distance. This may be due to the inclusion of longer training runs in preparation for marathons or to genetic or other innate differences between marathon and nonmarathon runners.

Abstract
OBJECTIVE We examined whether adiposity and fitness explain the decrease in health-related quality of life (HRQOL) associated with type 2 diabetes mellitus. METHODS This was a cross-sectional study using baseline data from two exercise training interventions. One study enrolled people with and the other without type 2 diabetes. We assessed aerobic fitness ("fitness") as peak oxygen uptake during treadmill testing, adiposity ("fatness") as percentage of total body fat by dual-energy x-ray absorptiometry, and HRQOL by the Medical Outcomes Study SF-36. Bivariate and multivariate linear regression analyses were used examine determinants of HRQOL were used to examine determinants of HRQOL. RESULTS There were 98 participants with and 119 participants without type 2 diabetes. Participants with type 2 diabetes had a mean hemoglobin A1c of 6.6% and, compared with participants without diabetes had lower HRQOL on the physical component summary score (P = 0.004), role-physical (P = 0.035), vitality (P = 0.062) and general health (P < 0.001) scales after adjusting for age, sex and race. These associations of HRQOL with type 2 diabetes were attenuated by higher fitness, even more than reduced fatness. Only general health remained positively associated with type 2 diabetes after accounting for fatness or fitness (P = 0.003). There were no significant differences between participants with and without diabetes in the mental component score. CONCLUSION Improved fitness, even more than reduced fatness, attenuated the association of type 2 diabetes with HRQOL. The potential to improve HRQOL may motivate patients with type 2 diabetes to engage in physical activity aimed at increasing fitness. Findings from this cross-sectional analysis will be addressed in the ongoing trial of exercise training in this cohort of participants with type 2 diabetes. TRIAL REGISTRATION NCT00212303.

Abstract
Lifestyle intervention programs encompassing exercise and healthy diets are an option for the treatment and management of obesity and type 2 diabetes and have long been known to exert beneficial effects on whole-body metabolism, in particular leading to enhanced insulin-sensitivity. Obesity is associated with increased risk of several illnesses and premature mortality. However, physical inactivity is itself associated with a number of similar risks, independent of body-mass index, and is an independent risk factor for more than 25 chronic diseases, including type 2 diabetes and cardiovascular disease. This article addresses the debate regarding the relative effects of physical exercise itself and the effect of exercise-induced weight loss.

Abstract
AIM Effects of dietary weight loss on endothelial function, particularly when combined with exercise training, is largely unknown in type 2 diabetes. We sought to determine whether aerobic exercise training provided any additional improvements in endothelial function, oxidative stress or other established markers of cardiovascular risk when combined with an energy-restricted diet in patients with type 2 diabetes. METHODS In a parallel study design, 29 sedentary, overweight and obese patients with type 2 diabetes (age 52.4 +/- 1.4 years and BMI 34.2 +/- 0.9 kg/m(2)) were randomized to a 12-week moderate energy-restricted diet (~5000 kJ/day and approximately 30% energy deficit) with or without aerobic exercise training [diet only (D), n = 16 and diet plus exercise (DE), n = 13]. Body weight, cardiovascular risk markers, malondialdehyde (MDA, oxidative stress marker), 24-h urinary nitrate/nitrite and flow-mediated dilatation (FMD) of the brachial artery were measured pre- and postintervention. RESULTS Both interventions reduced body weight (D 8.9%, DE 8.5%, time effect p < 0.001). Significant reductions in body fat, waist circumference, blood pressure, glycated haemoglobin, glucose, insulin resistance, lipids and MDA and increases in urinary nitrite/nitrate were observed in both groups (time effect p < or = 0.05); however, these changes were not different between treatments. At baseline, FMD was similar in both groups (D 2.5 +/- 0.9%, DE 4.2 +/- 1.2%; p = 0.25) and did not change after the interventions (p = 0.59). CONCLUSIONS These results suggest that lifestyle interventions incorporating diet with or without exercise improve glycaemic control, reduce oxidative stress and improve other cardiovascular risk factors but do not improve FMD in obese subjects with type 2 diabetes.

Abstract
BACKGROUND Prevention of type 2 diabetes in adults is a far better option than treatment, to alleviate pressure on health care providers and resources. However, there is no current review of the evidence regarding the efficacy of a diet-only intervention for prevention. OBJECTIVES To assess the effects of type and frequency of dietary advice for the prevention of type 2 diabetes mellitus. SEARCH STRATEGY We carried out a comprehensive search of The Cochrane Library, MEDLINE, EMBASE, CINAHL, AMED, bibliographies and contacted relevant experts. SELECTION CRITERIA All randomised controlled trials, of twelve months or longer, in which dietary advice for the prevention of type 2 diabetes was the only intervention in adults. DATA COLLECTION AND ANALYSIS The lead investigator performed all data extraction and quality scoring with duplication being carried out by one of the other four investigators independently with discrepancies resolved by discussion and consensus. Authors were contacted for missing data. Change data are presented. MAIN RESULTS Two trials which randomised 358 people to dietary treatment and control groups were identified. Longest duration of follow-up was six years. In the 6-year Da Qing IGT & Diabetes study, the incidence of type 2 diabetes in the control group was 67.7% (95% confidence interval (CI) 59.8% to 75.2%) which was reduced to 43.8% (95% CI 35.5% to 54.7%) in the diet group. Overall, the dietary intervention group had a 33% reduction in the incidence of diabetes after six years (P < 0.03). The Oslo Diet & Exercise Study (ODES) found significant (P<0.05) reductions in insulin resistance, fasting insulin (pmol/L), fasting C-peptide (pmol/L), fasting proinsulin (pmol/L), fasting blood glucose (mmol/L), BMI (kg/m(2)), mBP (mmHg) and fasting triglycerides (mmol/L), and a significant increase in fasting HDL cholesterol (mmol/L) and PAI-1 (U/ml) after 12 months of dietary intervention. Data on mortality, morbidity, health-related quality of life, adverse effects, costs were not reported in either study. AUTHORS' CONCLUSIONS There are no high quality data on the efficacy of dietary intervention for the prevention of type 2 diabetes. More well-designed, long-term studies, providing well-reported, high-quality data are required before proper conclusions can be made into the best dietary advice for the prevention of diabetes mellitus in adults.

Abstract
Common complications of type 2 diabetes (T2D) are eye, kidney and nerve diseases, as well as an increased risk for the development of cardiovascular disease and cancer. The overwhelming influence of these conditions contributes to a decreased quality of life and life span, as well as significant economic consequences. Although obesity once served as a surrogate marker for the risk of T2D, we know now that excess adipose tissue secretes inflammatory cytokines that left unchecked, accelerate the progression to insulin resistance and T2D. In addition, excess alcohol consumption may also increase the risk of T2D. From a therapeutic standpoint, lifestyle interventions such as dietary modification and/or exercise training have been shown to improve glucose homeostasis but may not normalize the disease process unless weight loss is achieved and increased physical activity patterns are established. Furthermore, utilization of natural products may serve as a significant adjunct in the fight against insulin resistance but further research is needed to ascertain their validity. Since it is clear that pharmaceutical therapy plays a significant role in the treatment of insulin resistance, this review will also discuss some of the newly developed pharmaceutical therapies that may work in conjunction with lifestyle interventions, and lessen the burden of behavioral change as the only strategy against the development of T2D.

Abstract
PURPOSE The purpose of this systematic review is to assess and summarize evidence and gaps in the literature regarding the intervention for being active (exercise) among individuals with diabetes. METHODS Twelve electronic databases were searched. Publications eligible for inclusion specifically studied learning, behavioral, clinical, and humanistic outcomes for exercise interventions in adult patients with type 1 and type 2 diabetes. RESULTS Seven reviews (2 systematic reviews, 3 meta-analyses, 2 technical reviews) and 34 individual, nonreview studies (18 randomized controlled trials, 16 nonrandomized trials) met inclusion criteria. For type 2 diabetes, findings suggested that exercise had a positive effect on glycemic control and decreased cardiovascular risk, but the impact of exercise on behavioral and humanistic outcomes was unclear; long-term outcomes and adherence to exercise interventions is unknown because most studies were of short duration. The overall impact of varied types of exercise in type 1 diabetes was unclear, especially regarding glycemic control. Potential benefits of exercise in type 1 may include improved cardiovascular health. CONCLUSION The review did not identify specific successful intervention details because of the heterogeneity of studies, subjects, and research gaps. General findings suggest that physical activity is better than no exercise at all; intensive regimens, if tolerated by patients, achieved better clinical outcomes than less intensive regimens. Reviewed studies using structured exercise regimens exhibited a more significant impact on outcomes. Substantial gaps in the literature include studies measuring direct effects of exercise in the US minority populations most affected by type 2 diabetes and economic evaluations of exercise interventions. Interventions must be tailored to individual patient needs to succeed.

Abstract
BACKGROUND While initial dietary management immediately after formal diagnosis is an 'accepted' cornerstone of treatment of type 2 diabetes mellitus, a formal and systematic overview of its efficacy and method of delivery is not currently available. OBJECTIVES To assess the effects of type and frequency of different types of dietary advice for adults with type 2 diabetes. SEARCH STRATEGY We carried out a comprehensive search of The Cochrane Library, MEDLINE, EMBASE, CINAHL, AMED, bibliographies and contacted relevant experts. SELECTION CRITERIA All randomised controlled trials, of six months or longer, in which dietary advice was the main intervention. DATA COLLECTION AND ANALYSIS The lead investigator performed all data extraction and quality scoring with duplication being carried out by one of the other six investigators independently with discrepancies resolved by discussion and consensus. Authors were contacted for missing data. MAIN RESULTS Thirty-six articles reporting a total of eighteen trials following 1467 participants were included. Dietary approaches assessed in this review were low-fat/high-carbohydrate diets, high-fat/low-carbohydrate diets, low-calorie (1000 kcal per day) and very-low-calorie (500 kcal per day) diets and modified fat diets. Two trials compared the American Diabetes Association exchange diet with a standard reduced fat diet and five studies assessed low-fat diets versus moderate fat or low-carbohydrate diets. Two studies assessed the effect of a very-low-calorie diet versus a low-calorie diet. Six studies compared dietary advice with dietary advice plus exercise and three other studies assessed dietary advice versus dietary advice plus behavioural approaches. The studies all measured weight and measures of glycaemic control although not all studies reported these in the articles published. Other outcomes which were measured in these studies included mortality, blood pressure, serum cholesterol (including LDL and HDL cholesterol), serum triglycerides, maximal exercise capacity and compliance. The results suggest that adoption of regular exercise is a good way to promote better glycaemic control in type 2 diabetic patients, however all of these studies were at high risk of bias. AUTHORS' CONCLUSIONS There are no high quality data on the efficacy of the dietary treatment of type 2 diabetes, however the data available indicate that the adoption of exercise appears to improve glycated haemoglobin at six and twelve months in people with type 2 diabetes. There is an urgent need for well-designed studies which examine a range of interventions, at various points during follow-up, although there is a promising study currently underway.

Abstract
OBJECTIVE This study examines the association of walking with mortality in persons with type 2 diabetes compared to those with normal glucose tolerance. STUDY DESIGN AND SETTING This prospective study included community-dwelling adults from the Rancho Bernardo Study aged 50-90 years in 1984-86 who had type 2 diabetes (n=347) or normal glucose tolerance (n=1,317). During the 10-year follow up, Cox proportional hazards modeling was used to model time until death from all causes (n=538), coronary heart disease (CHD, n=143), other cardiovascular disease (non-CHD CVD, n=138), and other causes (n=257) while adjusting for multiple potential confounders. RESULTS After adjusting for sex, age, smoking, body mass index, alcohol, exercise, history of CHD, and other covariates, adults with diabetes who walked > or =1 mile per day were half as likely to die from all causes combined (hazard ratio [HR]=0.54; 95% confidence interval [CI]: 0.33, 0.88), and less than one-fifth as likely to die from non-CHD CVD (HR=0.19; 95% CI: 0.04, 0.86) compared to adults with diabetes who did not walk. Walking was also protective among adults with normal glucose tolerance (HR=0.55; 95% CI: 0.32, 0.96). CONCLUSION Results suggest walking > or =1 mile per day may provide strong protection from all-cause and non-CHD CVD mortality in older adults with diabetes.

Abstract
This pilot study assessed the effects of exercise and nutritional counseling on hormonal, menstrual, and reproductive function in women with polycystic ovary syndrome (PCOS). Twelve females with a clinical, biochemical, and ultrasonographic diagnosis of PCOS were randomly assigned to endurance and resistance exercise plus nutritional counseling (EN) or nutritional counseling only (N) for a period of 12 weeks. Anthropometry, resting metabolic rate (RMR), selected hormones, and ovarian follicle population were measured pre and post-intervention. Following the 12 week intervention, greater decreases in sum of 2 skinfolds (p = 0.002) and a greater increase in estimated VO2 max (p = 0.017) occurred in the exercise group. Significant decreases in waist girth (p = 0.001) and insulin levels (p = 0.03) occurred in both groups. Hormonal changes were not statistically significant; however, a trend towards an improved hormonal profile, specifically sex-hormone binding globulin (EN, 39% increase; N, 8% increase) and lutenizing hormone : follicle-stimulating hormone (LH:FSH) (EN, 9% decrease; N, 27% decrease) occurred in the absence of weight loss. These findings suggest exercise and nutritional counseling may benefit the metabolic and reproductive abnormalities associated with PCOS.

Abstract
The aim of this study was to examine the effects of a 6-month intensive lifestyle modification intervention on metabolic parameters and carotid intima-media thickness (IMT) in patients with type 2 diabetes mellitus. Fifty-eight subjects with type 2 diabetes mellitus were randomly assigned to the intervention group or the control group. The subjects in the intervention group participated in a 16-week intensive lifestyle modification program and subsequent monthly meetings during the 6-month study period. Control subjects received basic dietary education and usual care. Anthropometric data, metabolic parameters, and carotid IMT were examined before the intervention and after 6 months. Lifestyle modification intervention group patients showed a significant reduction in HbA1c (-1.0% +/- 1.3% vs +0.1% +/- 1.2%, P = .002), fasting blood glucose (-1.6 +/- 1.5 vs +0.3 +/- 2.5 mmol/L, P = .001), and 2-hour postprandial plasma glucose (-2.1 +/- 2.5 vs +0.8 +/- 4.4 mmol/L, P = .003) compared with control patients after 6 months. Body weight (-2.0 +/- 2.6 vs +0.2 +/- 1.7 kg, P = .001), body mass index (-0.8 +/- 1.0 vs 0.0 +/- 0.8 kg/m2, P = .003), and systolic blood pressure (-8.2 +/- 15.9 vs +0.4 +/- 14.1 mm Hg, P = .041) were significantly decreased in the intervention group. A significantly reduced carotid mean IMT progression was seen in the intervention group after 6 months (-0.040 +/- 0.136 vs +0.083 +/- 0.167 mm, P = .007). Changes in HbA1c (r = 0.34, P = .028), fasting plasma glucose (r = 0.31, P = .045), and 2-hour postprandial plasma glucose (r = 0.37, P = .015) correlated with the mean carotid IMT change after adjustment for age and sex. In conclusion, a 6-month intensive lifestyle modification intervention in patients with type 2 diabetes mellitus resulted in improved glycemic control and decreased progression of carotid IMT.

Abstract
Exercise programs for elderly patients have received much attention recently for their potential role in preventing illness and injury, limiting functional loss and disability, and alleviating the course and symptoms of existing cardiac, pulmonary, and metabolic disorders. The basic components of an exercise training program include strength, endurance, balance, and flexibility. This article reviews the main attributes of each, along with some of the most recent research defining their roles in health care. Where available, it discusses specific recommendations for prescribing exercise modalities. Finally, it presents suggestions for developing integrated exercise programs and enhancing patient compliance.

Abstract
Musculoskeletal radiology, like most areas of diagnostic radiology, has seen a dramatic increase in the use of cross-sectional imaging techniques over the last decade. However, conventional radiography remains a vital role in the evaluation of disease involving the spine and extremities. Given its widespread availability and low cost, radiography should be the initial examination obtained when imaging is clinically indicated. Therefore it is essential that the practicing radiologists be able to maximize the diagnostic value of this common study to aid the clinicians with a focused differential diagnosis, if not a definitive diagnosis. While much emphasis has been placed on radiographic interpretation of osseous lesions, similar diagnostic yield can be often obtained about calcified or ossified soft-tissue lesions. Detailed evaluation of the distribution and morphology of the soft-tissue calcifications, combined with a thorough knowledge of the entities that may occur at the site of the noted abnormality, provides significant interpretive value to provide a definitive diagnosis or accurately recommend the next most effective management step. We provide a compartmental-based approach to the interpretation of soft-tissue calcifications.

Abstract
Historically, epidemiologic studies have reported a lower prevalence of impaired glucose tolerance and type 2 diabetes in populations consuming large amounts of the n-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFAs) found mainly in fish. Controlled clinical studies have shown that consumption of n-3 LC-PUFAs has cardioprotective effects in persons with type 2 diabetes without adverse effects on glucose control and insulin activity. Benefits include lower risk of primary cardiac arrest; reduced cardiovascular mortality, particularly sudden cardiac death; reduced triglyceride levels; increased high-density lipoprotein levels; improved endothelial function; reduced platelet aggregability; and lower blood pressure. These favorable effects outweigh the modest increase in low-density lipoprotein levels that may result from increased n-3 LC-PUFA intake. Preliminary evidence suggests increased consumption of n-3 LC-PUFAs with reduced intake of saturated fat may reduce the risk of conversion from impaired glucose tolerance to type 2 diabetes in overweight persons. Reported improvements in hemostasis, slower progression of artery narrowing, albuminuria, subclinical inflammation, oxidative stress, and obesity require additional confirmation. Expected health benefits and public health implications of consuming 1 to 2 g/day n-3 LC-PUFA as part of lifestyle modification in insulin resistance and type 2 diabetes are discussed.

Abstract
Sedentary death syndrome (SeDS) is a major public health burden due to its causing multiple chronic diseases and millions of premature deaths each year. Despite the impact of physical inactivity, very little is known about the actual causes of physical inactivity-induced chronic diseases. It is important to study the mechanisms underlying molecular changes related to physical inactivity in order to better understand the scientific basis of individualized exercise prescription and therapies for chronic diseases, and to support improved public health efforts by providing molecular proof that physical inactivity is an actual cause of chronic diseases. Physical activity has a genetic basis. A subpopulation of genes, which have functioned to support physical activity for survival through most of humankind's existence, require daily exercise to maintain long-term health and vitality. Type 2 diabetes (T2D) is an example of a SeDS condition, as it is almost entirely preventable with physical activity. To determine the true role of physical inactivity in the development and progression of T2D, information is presented which indicates that comparisons should be made to physically active controls, rather than sedentary controls, as this population is the healthiest. Use of sedentary subjects as the control group has led to potentially misleading interpretations. If physically active individuals were designated as the control group, a different interpretation would have been drawn. It is thought that there is no difference in GLUT4 concentration between T2D and sedentary groups. However, GLUT4 expression is higher in active controls than in sedentary and T2D groups. Therefore, to obtain causal mechanisms for SeDS in order to allow for scientifically based prevention and therapy strategies, physically active subjects must serve as the control group.

Abstract
Cardiovascular disease is the leading cause of mortality among people with diabetes mellitus, accounting for 70% of all deaths. As the prevalence of diabetes increases significantly worldwide, greater attention must be focused on preventing cardiovascular events in this group. One contributor to this increased event rate is the characteristic pattern of dyslipidemia in diabetic patients, consisting of elevated serum triglyceride levels, decreased high-density lipoprotein levels, and an increased proportion of small, dense, low-density lipoproteins. Several pharmacologic agents have been used to treat this dyslipidemia including HMG-CoA reductase inhibitors, fibric acid derivatives, niacin (nicotinic acid), thiazolidinediones, and fish oils, as well as other non-pharmacologic measures. Currently, the most extensive data for a reduction in cardiovascular events in patients with diabetes exist for HMG-CoA reductase inhibitors. The results of these trials indicate that HMG-CoA reductase inhibitor therapy should be considered for all patients with diabetes at sufficient risk for cardiovascular events, regardless of serum low-density lipoprotein-cholesterol level. Several ongoing trials of various pharmacologic agents should help clarify the role of these agents alone and in combination with HMG-CoA reductase inhibitors in the management of diabetic dyslipidemia.

Abstract
Little is known about the molecular changes in response to dietary restriction (energy and/or protein) in young growing skeletal muscles. To profile such changes and to gain insights into the signaling molecules that could mediate the diet effects, a dedicated porcine skeletal muscle cDNA-microarray approach was used to characterize differential muscle gene expression between conventionally fed and diet-restricted (20% less protein and 7% less energy) growing pigs, reared from 9 to 21 wk of age. In both red and white muscles, diet restriction resulted in the accumulation of significantly more intramuscular fat, and in the increased expression of genes involved in substrate (protein, glycogen, and lipid) turnover, in translation and mitochondrial function, and in raising glycolytic and oxidative phosphorylation potentials. The unexpected increase in intramuscular lipids in diet-restricted growing pigs could have important health implications for restricted diets in childhood. Despite reduced circulating insulin, more genes, including several novel growth modulatory genes, had higher expression levels, indicating that the cellular response to dietary restriction is an active process. One such responsive gene, P311, was most highly expressed in striated muscles and had a differentiation-dependent increase of expression in murine C2C12 cells, suggesting a role in differentiation/postdifferentiation phenotype determination.
