    2015-01-01

    Objective To determine whether some participants in the Diabetes Prevention Program were more or less likely to benefit from metformin or a structured lifestyle modification program. Design Post hoc analysis of the Diabetes Prevention Program, a randomized controlled trial. Setting Ambulatory care patients. Participants 3060 people without diabetes but with evidence of impaired glucose metabolism. Intervention Intervention groups received metformin or a lifestyle modification program with the goals of weight loss and physical activity. Main outcome measure Development of diabetes, stratified by the risk of developing diabetes according to a diabetes risk prediction model. Results Of the 3081 participants with impaired glucose metabolism at baseline, 655 (21%) progressed to diabetes over a median 2.8 years’ follow-up. The diabetes risk model had good discrimination (C statistic=0.73) and calibration. Although the lifestyle intervention provided a sixfold greater absolute risk reduction in the highest risk quarter than in the lowest risk quarter, patients in the lowest risk quarter still received substantial benefit (three year absolute risk reduction 4.9% v 28.3% in highest risk quarter; numbers needed to treat of 20.4 and 3.5, respectively). The benefit of metformin, however, was seen almost entirely in patients in the top quarter of risk of diabetes. No benefit was seen in the lowest risk quarter. Participants in the highest risk quarter averaged a 21.4% three year absolute risk reduction (number needed to treat 4.6). Conclusions Patients at high risk of diabetes have substantial variation in their likelihood of receiving benefit from diabetes prevention treatments. Using this knowledge could decrease overtreatment and make prevention of diabetes far more efficient, effective, and patient centered, provided that decision making is based on an accurate risk prediction tool.

    Over the past two decades, therapeutics for diabetes have evolved from drugs with known heart failure risk to classes with potential benefit for patients with heart failure. As many as 25 to 35 % of patients with heart failure carry a diagnosis of type 2 diabetes mellitus. Therefore, newer drug classes including dipeptidyl peptidase 4 (DPP-4) inhibitors, glucagon-like peptide 1 (GIP-1) agonists, and sodium-glucose cotransporter 2 (SGLT-2) inhibitors are being examined for cardiovascular safety as well as their effects on left ventricular function, quality of life, and other measures of disease progression. The purpose of this review is to summarize the existing evidence on these classes of anti-diabetic agents in patients with heart failure. PMID:27188181

  3. Diabetic foot risk assessment.

    2016-05-01

    Diabetes is a serious chronic disease that results in foot complications for many people world-wide. In 2014, the World Health Organization estimated the global prevalence of diabetes in adults to be 9%. To ascertain the risk that an individual patient might develop a diabetic foot ulcer that could lead to an amputation, clinicians are strongly encouraged to perform a risk assessment. Monteiro-Soares and Dinis-Ribeiro have presented a new DIAbetic FOot Risk Assessment with the acronym DIAFORA. It is different from other risk assessments in that it predicts the risk of developing both diabetic foot ulcers and amputation specifically. The risk variables were derived by regression analysis based on a data set of 293 patients from a high-risk setting, a Hospital Diabetic Foot Clinic, who had diabetes and a diabetic foot ulcers. Clear descriptions of the risk variables are provided as well as sensitivity, specificity, positive and negative predictive values for the risk categories. As an added benefit, likelihood ratios are provided that will help clinicians determine the risk of amputation for individual patients. Having a risk assessment form is important for clinician use and examples exist. A question is raised about the effectiveness of risk assessment and how effectiveness might be determined.

  4. Benefits & risks of statin therapy for primary prevention of cardiovascular disease in Asian Indians – A population with the highest risk of premature coronary artery disease & diabetes

    2013-01-01

    Several reviews and meta-analyses have demonstrated the incontrovertible benefits of statin therapy in patients with cardiovascular disease (CVD). But the role for statins in primary prevention remained unclear. The updated 2013 Cochrane review has put to rest all lingering doubts about the overwhelming benefits of long-term statin therapy in primary prevention by conclusively demonstrating highly significant reductions in all-cause mortality, major adverse cardiovascular events (MACE) and the need for coronary artery revascularization procedures (CARPs). More importantly, these benefits of statin therapy are similar at all levels of CVD risk, including subjects at low (<1% per year) risk of a MACE. In addition to preventing myocardial infarction (MI), stroke, and death, primary prevention with statins is also highly effective in delaying and avoiding expensive CARPs such as angioplasties, stents, and bypass surgeries. There is no evidence of any serious harm or threat to life caused by statin therapy, though several adverse effects that affect the quality of life, especially diabetes mellitus (DM) have been reported. Asian Indians have the highest risk of premature coronary artery disease (CAD) and diabetes. When compared with Whites, Asian Indians have double the risk of CAD and triple the risk of DM, when adjusted for traditional risk factors for these diseases. Available evidence supports the use of statin therapy for primary prevention in Asian Indians at a younger age and with lower targets for low-density lipoprotein cholesterol (LDL-C) and non-high density lipoprotein (non-HDL-C), than those currently recommended for Americans and Europeans. Early and aggressive statin therapy offers the greatest potential for reducing the continuing epidemic of CAD among Indians. PMID:24434254

    2014-03-01

    In the United States, life expectancy has markedly increased during the past century, and population ageing is expected to double within the next 25 years. The process of ageing in a population is associated with the development of chronic diseases, such as type 2 diabetes mellitus, that can be prevented, and even reversed, with the implementation of healthy lifestyle interventions. The evidence to date, consolidated by the numerous epidemiological studies and clinical trials conducted, suggests that caloric restriction is an effective nutritional intervention for preventing most of these age-related conditions. At a metabolic level, caloric restriction with adequate nutrition has been shown to improve insulin sensitivity, reduce fasting glucose and insulin concentration and prevent obesity, type 2 diabetes, hypertension and chronic inflammation. The purpose of this article is to review current knowledge of the metabolic and clinical implications of caloric restriction with adequate nutrition for the prevention of type 2 diabetes and cardiovascular disease.

    2012-04-01

    The development of new drugs for the treatment of type 2 diabetes (T2DM) and metabolic disorders is currently one of the most innovative areas of drug development. However, a considerable number of newly developed drugs have either not reached the market and were stopped late in development or have been withdrawn after initial approval soon after market authorization due to serious safety concerns. How can drug safety problems be anticipated and, even more important, how can adverse events definitely caused by a drug be differentiated from incidences of naturally occurring diseases? This review article will provide an update about the state of the art treatment of type 2 diabetes and reflect on the newest available study evidence on glitazones, incretin mimetics (GLP-1 agonists and DPP-4 inhibitors), SGLT-2 inhibitors (gliflocines) and pan-PPAR agonists (glitazars). Furthermore, new and still experimental approaches for the treatment of T2DM, such as bardoxolone, salsalate and anakinra will be briefly reviewed. PMID:22388922

    Simcox, Judith A.; McClain, Donald A.

    2013-01-01

    Iron overload is a risk factor for diabetes. The link between iron and diabetes was first recognized in pathologic conditions—hereditary hemochromatosis and thalassemia—but high levels of dietary iron also impart diabetes risk. Iron plays a direct and causal role in diabetes pathogenesis mediated both by β-cell failure and insulin resistance. Iron is also a factor in the regulation of metabolism in most tissues involved in fuel homeostasis, with the adipocyte in particular serving an iron-sensing role. The underlying molecular mechanisms mediating these effects are numerous and incompletely understood, but include oxidant stress and modulation of adipokines and intracellular signal transduction pathways.

    PubMed

    Rustenbeck, Ingo

    2016-02-01

    Currently, the therapy with oral antidiabetic drugs undergoes major changes. The use of sulfonylureas is in marked decline. The major argument in favor of newer oral antidiabetic drugs is the lower risk of hypoglycemia. At the present time however, it is unclear whether DDP4 inhibitors or SGLT2 inhibitors lead to better outcomes with respect to cardiovascular events and overall mortality. Most evidence on the therapeutic use of sulfonylureas has been gained with glibenclamide and to some degree sulfonylureas and glibenclamide have become synonymous. Since sulfonylureas vary considerably in their affinity for the K(ATP) channel subtypes and in their pharmacokinetic properties, the epidemiological evidence that outcomes tend to be less favorable with glibenclamide than with glimepiride or gliclazide has gained some attention. Beyond debate is the efficacy of metformin to diminish cardiovascular events in type 2 diabetes, probably due to effects beyond the lowering of blood glucose. PMID:26983335

    Abstract To systematically assess the effect of metformin on colorectal cancer (CRC) risk and mortality in type 2 diabetes mellitus (T2DM) patients. We conducted a systematic search of PubMed, Web of Science, and the Cochrane Library databases for relevant articles before August 2015. Two investigators identified and extracted data independently. We adopted adjusted estimates to calculate summary estimates with 95% confidence interval (CI) using either a fixed-effects or a random-effects model. Subgroup and sensitivity analyses were conducted to evaluate the robustness of the pooled results. The risk of publication bias was assessed by examining funnel plot asymmetry as well as Begg test and Egger test. Fifteen studies on CRC incidence and 6 studies on CRC survival were finally included in our meta-analysis. The pooled odds ratio (OR) of observational studies illustrated that a slight 10% reduction of CRC incidence was associated with metformin use (OR = 0.90, 95% CI: 0.85–0.96). Furthermore, the pooled hazard ratio (HR) revealed an improved survival outcome for metformin users in CRC patients compared to nonusers (HR = 0.68, 95% CI: 0.58–081). There was no publication bias across studies. Our meta-analysis demonstrated that metformin therapy could slightly reduce CRC incidence and moderately improve the survival outcomes in patients with T2DM. More prospective studies are warranted to certify this protective association. PMID:26886616

    This paper uses regression techniques to take a second look at a classic risk-perception data set originally collected by Paul Slovic, Sarah Lichtenstein, and Baruch Fischhoff. As discussed in earlier studies, the attributes expected mortality, effects on future generations, immediacy, and catastrophic potential all significantly affect risk ratings. However, the authors find that perceived risk and dread show different regression patterns; most importantly, only perceived risk ratings correlate with expected mortality. In addition, average risk ratings are found to be significantly affected by perceived individual benefits, which suggests that perceptions of risk are net rather than gross indicators of harm. 14 refs., 3 tabs.

    The 3-hydroxy-methylglutaryl coenzyme A reductase inhibitors, statins, are widely used in the primary and secondary prevention of cardiovascular diseases to lower serum cholesterol levels. As type 2 diabetes mellitus is accompanied by dyslipidemia, statins have a major role in preventing the long term complications in diabetes and are recommended for diabetics with normal low density lipoprotein levels as well. In 2012, United States Food and Drug Administration released changes to statin safety label to include that statins have been found to increase glycosylated haemoglobin and fasting serum glucose levels. Many studies done on patients with cardiovascular risk factors have shown that statins have diabetogenic potential and the effect varies as per the dosage and type used. The various mechanisms for this effect have been proposed and one of them is downregulation of glucose transporters by the statins. The recommendations by the investigators are that though statins can have diabetogenic risk, they have more long term benefits which can outweigh the risk. In elderly patients and those with metabolic syndrome, as the risk of diabetes increase, the statins should be used cautiously. Other than a subset of population with risk for diabetes; statins still have long term survival benefits in most of the patients. PMID:25789118

    Diabetic clients must make daily decisions about their health care needs. Observational and anecdotal evidence suggests that vast differences exist between the kinds of choices diabetic clients make and the kinds of chances they are willing to take. The purpose of this investigation was to develop a diabetic risk-assessment tool. This instrument, which is based on subjective expected utility theory, measures risk-prone and risk-averse behavior. Initial findings from a pilot study of 18 women clients who are on insulin indicate that patterns of risk behavior exist in the areas of exercise, skin care, and diet. PMID:1729123

    OBJECTIVE Two meta-analyses of randomized trials of statins found increased risk of type 2 diabetes. One possible explanation is bias due to differential survival when patients who are at higher risk of diabetes survive longer under statin treatment. RESEARCH DESIGN AND METHODS We used electronic medical records from 500 general practices in the U.K. and included data from 285,864 men and women aged 50–84 years from January 2000 to December 2010. We emulated the design and analysis of a hypothetical randomized trial of statins, estimated the observational analog of the intention-to-treat effect, and adjusted for differential survival bias using inverse-probability weighting. RESULTS During 1.2 million person-years of follow-up, there were 13,455 cases of type 2 diabetes and 8,932 deaths. Statin initiation was associated with increased risk of type 2 diabetes. The hazard ratio (95% CI) of diabetes was 1.45 (1.39–1.50) before adjusting for potential confounders and 1.14 (1.10–1.19) after adjustment. Adjusting for differential survival did not change the estimates. Initiating atorvastatin and simvastatin was associated with increased risk of type 2 diabetes. CONCLUSIONS In this sample of the general population, statin therapy was associated with 14% increased risk of type 2 diabetes. Differential survival did not explain this increased risk.

    Sodium-glucose co-transporter 2 (SGLT2) inhibitors, such as canagliflozin, are used in patients with Type 2 diabetes mellitus (T2DM). In clinical studies, canagliflozin significantly reduced A1C, bodyweight and blood pressure, and was generally well tolerated with no increased risk of hypoglycemia. Most common adverse effects observed were genital mycotic infections and urinary tract infections, and increased urination. Approximately 10% of women treated with canagliflozin experienced a genital mycotic infection compared with 3% treated with placebo; those with a prior history were at greater risk. Approximately 9% of women treated with canagliflozin reported a urinary tract infection compared with 7% treated with placebo. Most adverse events were considered mild to moderate in intensity and responded to standard therapy. Treatment with canagliflozin was effective and generally well tolerated in both women (and men) with T2DM. PMID:26928259

  1. Calcium supplements: benefits and risks.

    2015-10-01

    Calcium is an essential element in the diet, but there is continuing controversy regarding its optimal intake, and its role in the pathogenesis of osteoporosis. Most studies show little evidence of a relationship between calcium intake and bone density, or the rate of bone loss. Re-analysis of data from the placebo group from the Auckland Calcium Study demonstrates no relationship between dietary calcium intake and rate of bone loss over 5 years in healthy older women with intakes varying from <400 to >1500 mg day(-1) . Thus, supplements are not needed within this range of intakes to compensate for a demonstrable dietary deficiency, but might be acting as weak anti-resorptive agents via effects on parathyroid hormone and calcitonin. Consistent with this, supplements do acutely reduce bone resorption and produce small short-term effects on bone density, without evidence of a cumulative density benefit. As a result, anti-fracture efficacy remains unproven, with no evidence to support hip fracture prevention (other than in a cohort with severe vitamin D deficiency) and total fracture numbers are reduced by 0-10%, depending on which meta-analysis is considered. Five recent large studies have failed to demonstrate fracture prevention in their primary analyses. This must be balanced against an increase in gastrointestinal side effects (including a doubling of hospital admissions for these problems), a 17% increase in renal calculi and a 20-40% increase in risk of myocardial infarction. Each of these adverse events alone neutralizes any possible benefit in fracture prevention. Thus, calcium supplements appear to have a negative risk-benefit effect, and so should not be used routinely in the prevention or treatment of osteoporosis. PMID:26174589

    1981-01-01

    Circumcisions are performed either prophylactically in the neonatal period or therapeutically at a later age. About 10% of males not circumcised at birth will eventually require circumcision. The present neonatal circumcision rate is about 80% in the United States and 40% in Canada. The single most important determinant of whether a newborn male will be circumcised is the attitude of the attending physician. The literature was reviewed to determine the proven benefits of circumcision and to compare these with the known risks. Circumcising the newborn facilitates penile hygiene, prevents cancer of the penis and decreases the incidence of genital herpes in later life. Whether it decreases the incidence of cancer of the cervix is still uncertain. More important, neonatal circumcision is associated with much lower morbidity and mortality and with lower costs than therapeutic circumcision. Thus, prophylactic circumcision is recommended for the male population as a whole. PMID:7037142

    The recent convention of introducing phytochemicals to support the immune system or combat diseases is a centuries' old tradition. Nutritional support is an emerging advancement in the domain of diet-based therapies; tea and its constituents are one of the significant components of these strategies to maintain the health and reduce the risk of various malignancies. Tea is the most frequently consumed beverage worldwide, besides water. All the three most popular types of tea, green (unfermented), black (fully fermented), and oolong (semifermented), are manufactured from the leaves of the plant Camellia sinensis. Tea possesses significant antioxidative, anti-inflammatory, antimicrobial, anticarcinogenic, antihypertensive, neuroprotective, cholesterol-lowering, and thermogenic properties. Several research investigations, epidemiological studies, and meta-analyses suggest that tea and its bioactive polyphenolic constituents have numerous beneficial effects on health, including the prevention of many diseases, such as cancer, diabetes, arthritis, cardiovascular disease (CVD), stroke, genital warts, and obesity. Controversies regarding beneficialts and risks of tea consumption still exist but the limitless health-promoting benefits of tea outclass its few reported toxic effects. However, with significant rise in the scientific investigation of role of tea in human life, this review is intended to highlight the beneficial effects and risks associated with tea consumption.

    In 1990, iodine deficiency affected almost one-third of the world population and was the greatest single cause of preventable brain damage and mental retardation. Following a resolution adopted by the World Summit for Children in 1990. major programmes of iodine supplementation were implemented by the governments of the affected countries with the support of major donors. Iodisation of salt was recognised as the method of choice. Nine years later, by April 1999, 75% of the affected countries had legislation on salt iodisation and 68% of the affected populations had access to iodised salt. The prevalence of iodine deficiency disorders decreased drastically in most countries and the deficiency disappeared completely in some such as Peru. This result constitutes a public heath success unprecedented with a non-infectious disease. However, occasional adverse effects occurred. The principle effect is iodine-induced hyperthyroidism which occurs essentially in older people with autonomous nodular goitres, especially following iodine intake that is too rapid and of too massive an increment. The incidence of the disorder is usually low and reverts spontaneously to the background rate of hyperthyroidism or even below this rate after 1 to 10 years of iodine supplementation. The possible occurrence of iodine-induced thyroiditis in susceptible individuals has not been clearly demonstrated by large epidemiological surveys. Iodine supplementation is followed by an increased prevalence of occult papillary carcinoma of the thyroid discovered at autopsy but the prognosis of thyroid cancer is improved due to a shift towards differentiated forms of thyroid cancer that are diagnosed at earlier stages. Iodine-induced hyperthyroidism and other adverse effects can be almost entirely avoided by adequate and sustained quality control and monitoring of iodine supplementation which should also confirm adequate iodine intake. Available evidence clearly confirms that the benefits of correcting

    Insulin pump therapy, also known as continuous subcutaneous insulin infusion (CSII), is an important and evolving form of insulin delivery, which is mainly used for people with type 1 diabetes. However, even with modern insulin pumps, errors of insulin infusion can occur due to pump failure, insulin infusion set (IIS) blockage, infusion site problems, insulin stability issues, user error, or a combination of these. Users are therefore exposed to significant and potentially fatal hazards: interruption of insulin infusion can result in hyperglycemia and ketoacidosis; conversely, delivery of excessive insulin can cause severe hypoglycemia. Nevertheless, the available evidence on the safety and efficacy of CSII remains limited. The European Association for the Study of Diabetes (EASD) and the American Diabetes Association (ADA) have therefore joined forces to review the systems in place for evaluating the safety of pumps from a clinical perspective. We found that useful information held by the manufacturing companies is not currently shared in a sufficiently transparent manner. Public availability of adverse event (AE) reports on the US Food and Drug Administration's Manufacturer and User Facility Device Experience (MAUDE) database is potentially a rich source of safety information but is insufficiently utilized due to the current configuration of the system; the comparable database in Europe (European Databank on Medical Devices [EUDAMED]) is not publicly accessible. Many AEs appear to be attributable to human factors and/or user error, but the extent to which manufacturing companies are required by regulators to consider the interactions of users with the technical features of their products is limited. The clinical studies required by regulators prior to marketing are small and over-reliant on bench testing in relation to "predicate" products.

    Objective: To identify and assess studies investigating the association between statins and new-onset diabetes and determine the clinical significance of this risk. Data sources: A MEDLINE (1977–April 2015), Google Scholar (1997–April 2015), and International Pharmaceutical Abstracts (1977–April 2015) search was performed using the search terms hydroxymethylglutaryl-CoA reductase inhibitors, hydroxymethylglutaryl-CoA reductase inhibitors/adverse effects, statins, adverse effects, diabetes mellitus, diabetes mellitus/etiology, and drug-induced. Citations of identified articles and clinical practice guidelines were also reviewed. Study selection and data extraction: Articles describing results from original investigations or meta-analyses specifically designed to assess the association between statins and new-onset diabetes and published in English were included. Data synthesis: A total of 13 cohort studies and seven meta-analyses were included. In all, 11 were retrospective cohort studies and reported some degree of increased risk of new-onset diabetes associated with statins. The two prospective cohort studies differed. One identified increased risk of new-onset diabetes, but the other did not. Increased risk was not identified when any statin was compared to placebo alone, individual statins were compared, or in the single meta-analysis that included observational studies. Overall, the meta-analyses suggest that statin therapy is associated with an increased risk of new-onset diabetes when compared to placebo or active control, and when intensive therapy is compared to moderate therapy. Conclusion: Statins have been associated with a small, but statistically significant risk of new-onset diabetes. Patients with risk factors for developing diabetes mellitus may be at higher risk. This risk is likely outweighed by the benefits of reducing cardiovascular risk. PMID:26770803

    Objective The study objective was to examine the association between menopause status and diabetes risk among women with glucose intolerance and to determine if menopausal status modifies response to diabetes prevention interventions. Methods The study population included women in premenopause (n=708), natural postmenopause (n=328), and bilateral oophorectomy (n=201) in the Diabetes Prevention Program (DPP), a randomized placebo-controlled trial of lifestyle intervention and metformin among glucose intolerant adults. Associations between menopause and diabetes risk were evaluated using Cox proportional hazard models that adjusted for demographic variables (age, race/ethnicity, family history of diabetes, history of gestational diabetes mellitus), waist circumference, insulin resistance and corrected insulin response. Similar models were constructed after stratification by menopause type and hormone therapy (HT) use. Results After adjustment for age, there was no association between natural menopause or bilateral oophorectomy and diabetes risk. Differences by study arm were observed in women who reported bilateral oophorectomy. In the lifestyle arm, women with bilateral oophorectomy had a lower adjusted hazard for diabetes (HR 0.19, 95% CI 0.04, 0.94), although observations were too few to determine if this was independent of HT use. No significant differences were seen in the metformin (HR 1.29, 95% CI 0.63, 2.64) or placebo arms (HR 1.37, 95% CI 0.74, 2.55). Conclusions Among women at high-risk for diabetes, natural menopause was not associated with diabetes risk and did not affect response to diabetes prevention interventions. In the lifestyle intervention, bilateral oophorectomy was associated with decreased diabetes risk. PMID:21709591

    2016-10-01

    Type 2 diabetes is a chronic disease that is increasing in prevalence globally. Cardiovascular disease is a major cause of mortality and morbidity in diabetes, and lifestyle and clinical risk factors do not fully account for the link between the conditions. This article provides an overview of the evidence concerning the role of psychosocial stress factors in diabetes risk, as well as in cardiovascular complications in people with existing diabetes. Several types of psychosocial factors are discussed including depression, other types of emotional distress, exposure to stressful conditions, and personality traits. The potential behavioral and biological pathways linking psychosocial factors to diabetes are presented and implications for patient care are highlighted. PMID:27566328

  18. Managing benefits for diabetes: changing payer strategies for changing times.

    PubMed

    Tzeel, Albert

    2013-01-01

    Just as there are many ways to treat a condition such as diabetes, there are also many ways for payers to manage the diabetes benefit. Although none of these methods is specifically right or wrong, they are grounded in a payer's philosophy and created in response to the needs of the time. Yet, just as in any other business, new ideas and, for diabetes, new scientific discoveries will surely mandate new strategies to achieve goals. As payers find themselves adapting to new political realities and new partnerships, one cannot be sure if their new strategies will succeed or not. But, in actuality, this becomes moot as the 1 point we can be sure of is that benefit management will continue to evolve. PMID:23725238

  19. Gestational Diabetes Mellitus: Risks and Management during and after Pregnancy

    Buchanan, Thomas A.; Xiang, Anny H.; Page, Kathleen A.

    2015-01-01

    Gestational diabetes mellitus (GDM) represents glucose levels in the high end of the population distribution during pregnancy. GDM carries a small but potentially important risk of adverse perinatal outcomes and a longer-term risk of obesity and glucose intolerance in offspring. Mothers with GDM have an excess of hypertensive disorders during pregnancy and a high risk of diabetes mellitus thereafter. Diagnosing and treating GDM can reduce perinatal complications, but only a small fraction of pregnancies benefit. Nutritional management is the cornerstone of treatment; insulin, glyburide and metformin can be used to intensify treatment. Fetal measurements compliment maternal glucose measurements in identifying pregnancies that need such intensification. Glucose testing shortly after pregnancy can stratify the near-term diabetes risk in mothers, Thereafter, annual glucose and HbA1C testing can detect deteriorating glycaemic control, a harbinger of future diabetes, usually type 2. Interventions that mitigate obesity or its metabolic effects are most potent in preventing or delaying diabetes. Lifestyle modification is the primary approach; use of medications for diabetes prevention after GDM remains controversial. Family planning allows optimization of health in subsequent pregnancies. Breastfeeding may reduce obesity in children and is recommended. Families should be encouraged to help children adopt lifestyles that reduce the risk of obesity. PMID:22751341

    PubMed

    Rosta, András

    2011-07-17

    Type 2 diabetes mellitus and malignant tumors are frequent diseases worldwide. The incidence of these two diseases is growing continuously and causes serious health care problem. Population based epidemiologic studies show that the coexistence of type 2 diabetes and malignant tumors is more frequent than expected by the age-corrected incidence and prevalence of each disease. Epidemiologic studies and meta-analyses show that type 2 diabetes increases the risk and tumor specific mortality of certain cancers. The overlapping risk factors of the diseases suggest a relationship between type 2 diabetes and malignant tumors, with a significant role of obesity as a major risk factor. In the pathophysiology of type 2 diabetes there are several biological processes, which may explain the higher cancer risk in type 2 diabetes. In vitro experiments, and in vivo animal studies show that the mitotic effect of hyperinsulinemia plays an important role in the relationship of cancer and type 2 diabetes mellitus. Recent studies show that the different treatment modalities, antidiabetic drugs and their combinations used for the treatment of type 2 diabetes can modify cancer risk. The majority of the data show that metformin therapy decreases, while insulin secretagog drugs slightly increase the risk of certain types of cancers in type 2 diabetes. Metformin can decrease cell proliferation and induce apoptosis in certain cancer cell lines. Endogenous and exogenous (therapy induced) hyperinsulinemia may be mitogenic and may increase the risk of cancer in type 2 diabetes. Human studies showed that the analogue insulin glargin increases the risk of certain cancers. As a result of conceptual weaknesses in study design, data collection, and statistical methods the results of these studies are questionable. According to present knowledge, obtaining and maintaining optimal metabolic target values with the appropriate choice of treatment modality is the aim of treatment in type 2 diabetes

    2013-01-01

    Diabetes and cancer represent two complex, diverse, chronic, and potentially fatal diseases. Cancer is the second leading cause of death, while diabetes is the seventh leading cause of death with the latter still likely underreported. There is a growing body of evidence published in recent years that suggest substantial increase in cancer incidence in diabetic patients. The worldwide prevalence of diabetes was estimated to rise from 171 million in 2000 to 366 million in 2030. About 26.9% of all people over 65 have diabetes and 60% have cancer. Overall, 8–18% of cancer patients have diabetes. In the context of epidemiology, the burden of both diseases, small association between diabetes and cancer will be clinically relevant and should translate into significant consequences for future health care solutions. This paper summarizes most of the epidemiological association studies between diabetes and cancer including studies relating to the general all-site increase of malignancies in diabetes and elevated organ-specific cancer rate in diabetes as comorbidity. Additionally, we have discussed the possible pathophysiological mechanisms that likely may be involved in promoting carcinogenesis in diabetes and the potential of different antidiabetic therapies to influence cancer incidence.

  6. The Risks and Benefits of Calcium Supplementation

    Kim, Kyoung Min

    2015-01-01

    The association between calcium supplementation and adverse cardiovascular events has recently become a topic of debate due to the publication of two epidemiological studies and one meta-analysis of randomized controlled clinical trials. The reports indicate that there is a significant increase in adverse cardiovascular events following supplementation with calcium; however, a number of experts have raised several issues with these reports such as inconsistencies in attempts to reproduce the findings in other populations and questions concerning the validity of the data due to low compliance, biases in case ascertainment, and/or a lack of adjustment. Additionally, the Auckland Calcium Study, the Women's Health Initiative, and many other studies included in the meta-analysis obtained data from calcium-replete subjects and it is not clear whether the same risk profile would be observed in populations with low calcium intakes. Dietary calcium intake varies widely throughout the world and it is especially low in East Asia, although the risk of cardiovascular events is less prominent in this region. Therefore, clarification is necessary regarding the occurrence of adverse cardiovascular events following calcium supplementation and whether this relationship can be generalized to populations with low calcium intakes. Additionally, the skeletal benefits from calcium supplementation are greater in subjects with low calcium intakes and, therefore, the risk-benefit ratio of calcium supplementation is likely to differ based on the dietary calcium intake and risks of osteoporosis and cardiovascular diseases of various populations. Further studies investigating the risk-benefit profiles of calcium supplementation in various populations are required to develop population-specific guidelines for individuals of different genders, ages, ethnicities, and risk profiles around the world.

    2007-05-01

    Pharmaceutical innovation, together with rising education, sanitation and wealth, prolonged life expectancy in industrialised countries throughout the 20th century. At the turn of the 21st century, with many, formerly common, lethal diseases confined to the developing world, the benefits of medical intervention are taken for granted in industrialized countries, and the expectations of safety have risen considerably. The perception and tolerance of risk has changed largely in the absence of immediate, population-wide health threats. Here, we review selected examples of drug withdrawals and adverse drug effects, and their impact on public perception. We analyse the role of major players, such as the media, patients, prescribers, regulators and pharmaceutical companies, and what actions are needed to better describe and communicate the risks and benefits of medicines to the public.

  8. Benefits and risks of oral contraceptives.

    PubMed

    Sherif, K

    1999-06-01

    The major benefits of modern low-dose oral contraceptives include relative safety and a high degree of efficacy, decreasing the need for abortion or surgical sterilization; reduced risks of bacterial (but not viral) pelvic inflammatory disease and of endometrial and ovarian cancer; improved menstrual regularity, with less dysmenorrhea and blood flow; and, when low-dose combination (not progestogen-only) oral contraceptives are used, reduced acne and hirsutism. Major risks are cardiovascular. Preliminary data from nonrandomized studies suggest that oral contraceptives containing third-generation progestogens are associated with increased risk of venous thromboembolism, particularly in carriers of the coagulation factor V Leiden mutation. The risk of arterial thrombosis, such as myocardial infarction or stroke, may be directly related to estrogen dose, particularly in women who have hypertension, smoke, or are >35 years old. Considering that only users aged >/=30 years who smoke >/=25 cigarettes/d have a higher estimated mortality rate than that of pregnant women, the benefits of oral contraceptives appear to outweigh their risks.

    2014-01-01

    Disease risk factors identified in epidemiological studies serve as important public health tools, helping clinicians identify individuals who may benefit from more aggressive screening or risk-modification procedures, allowing policymakers to prioritize intervention programs, and encouraging at-risk individuals to modify behavior and improve their health. These factors have been based primarily on evidence from cross-sectional and prospective studies, as most do not lend themselves to randomized trials. While some risk factors are not modifiable, eating habits are subject to change through both individual action and broader policy initiatives. Meat consumption has been frequently investigated as a variable associated with diabetes risk, but it has not yet been described as a diabetes risk factor. In this article, we evaluate the evidence supporting the use of meat consumption as a clinically useful risk factor for type 2 diabetes, based on studies evaluating the risks associated with meat consumption as a categorical dietary characteristic (i.e., meat consumption versus no meat consumption), as a scalar variable (i.e., gradations of meat consumption), or as part of a broader dietary pattern.

  11. Cannabis and neuropsychiatry, 1: benefits and risks.

    PubMed

    Andrade, Chittaranjan

    2016-05-01

    Cannabis is popularly believed to be a relatively benign substance. Cannabis is also considered to have potential medical benefits, and medical marijuana has been legislated in many parts of the world. However, a recent meta-analysis found that cannabinoids were associated with only modest benefits for chemotherapy-related nausea and vomiting, small and inconsistent benefits for pain and spasticity, and inconclusive benefits for other indications such as improvement of appetite and weight, reduction in tic severity, and improvement of mood or sleep. On the flip side, cannabinoids and cannabis have acute and long-term adverse effects. In randomized controlled trials, cannabinoids increase the risk of total adverse events, serious adverse events, and dropout due to adverse events. Cannabis impairs cognition, and driving after cannabis use is associated with an increased risk of traffic accidents, including fatal accidents. Long-term cannabis use may lead to dependence, respiratory conditions, psychosis, and possibly cancer, as well. Cannabis use during pregnancy may compromise certain pregnancy outcomes such as fetal growth, and use during adolescence may compromise neurodevelopment, social adjustment, and vocational success. The composition and bioavailability of cannabis vary across preparations of the substance and routes of administration; this limits the ability to generalize the findings of studies. The findings of older research may no longer apply to current strains of cannabis that are higher in psychotogenic content. It is important for medical professionals and the lay public to understand the limitations of the efficacy data and the seriousness of the risks associated with cannabis use in medical and recreational contexts.

    Statins have a relevant role in decreasing cardiovascular mortality. Statins are effective in primary and secondary prevention. Recently, it has been suggested that statins may have a diabetogenic effect, because a moderate increase in the risk of newly developed diabetes mellitus was observed. The diabetogenic effect of statins is a group effect and it is dose-dependent, too. The effect of statins which lower the cardiovascular risk attenuates the risk of developing diabetes during statin therapy, too. Hence, statins remain the first line therapy of reaching LDL-cholesterol targets. PMID:24140507

Inversely, CVR of type 1 diabetes mellitus (T1DM) is currently being debated apart from the occurrence of diabetic nephropathy (DN). For this, we did a review of CVR in patients with T1DM complicated or not with DN.

    The effects of tree nuts on risk factors for coronary heart disease (CHD), in particular blood lipids, have been investigated in a number of studies and the beneficial effects are now recognized. The beneficial effects of nuts on CHD in cohort studies have also been clearly demonstrated. However, while there is also reason to believe the unique micro- and macronutrient profiles of nuts may help to control blood glucose levels, relatively few studies have investigated their role in diabetes control and prevention. Nuts are low in available carbohydrate, have a healthy fatty acid profile, and are high in vegetable protein, fiber and magnesium. Acute feeding studies indicate that when eaten alone nuts have minimal effects on raising postprandial blood glucose levels. In addition, when nuts are consumed with carbohydrate rich foods, they blunt the postprandial glycemic response of the carbohydrate meal. Despite the success of these acute studies, only a limited number of trials have been conducted with nuts in type 2 diabetes. These studies have either been of insufficient duration to observe changes in HbA1c, as the standard measure of glycemic control, or have been underpowered. Therefore, more long-term clinical trials are required to examine the role of nuts on glycemic control in patients with prediabetes and diabetes. Overall, there are good reasons to justify further exploration of the use of nuts in the prevention of diabetes and its micro- and macrovascular complications. PMID:20199995

    The likelihood and adverse impacts of water-related disasters, such as floods and landslides, are increasing in many countries because of changes in climate and land-use. This presentation illustrates some preliminary results of a comprehensive demonstration of the benefits of risk prevention measures, carried out within the European FP7 KULTURisk project. The study is performed by using a variety of case studies characterised by diverse socio-economic contexts, different types of water-related hazards (floods, debris flows and landslides, storm surges) and space-time scales. In particular, the benefits of state-of-the-art prevention initiatives, such as early warning systems, non-structural options (e.g. mapping and planning), risk transfer strategies (e.g. insurance policy), and structural measures, are showed. Lastly, the importance of homogenising criteria to create hazard inventories and build memory, efficient risk communication and warning methods as well as active dialogue with and between public and private stakeholders, is highlighted.

    Knowledge of the physiological mechanisms that govern cardiopulmonary interactions during cardiopulmonary resuscitation (CPR) allows to better assess risks and benefits of ventilation. Ventilation is required to maintain gas exchange, particularly when CPR is prolonged. Nevertheless, conventional ventilation (bag mask or mechanical ventilation) may be harmful when excessive or when chest compressions are interrupted. In fact large tidal volume and/or rapid respiratory rate may adversely compromise hemodynamic effects of chest compressions. In this regard, international recommendations that give the priority to chest compressions, are meaningful. Continuous flow insufflation with oxygen that generates a moderate positive airway pressure avoids any interruption of chest compressions and prevents the risk of lung injury associated with prolonged resuscitation.

    2016-10-01

    Inhibitors of sodium-glucose cotransporters type 2 (SGLT2) reduce hyperglycemia by increasing urinary glucose excretion. They have been evaluated in patients with type 2 diabetes treated with diet/exercise, metformin, dual oral therapy or insulin. Three agents are available in Europe and the USA (canagliflozin, dapagliflozin, empagliflozin) and others are commercialized in Japan or in clinical development. SGLT2 inhibitors reduce glycated hemoglobin, with a minimal risk of hypoglycemia. They exert favorable effects beyond glucose control with consistent body weight, blood pressure, and serum uric acid reductions. Empagliflozin showed remarkable reductions in cardiovascular/all-cause mortality and in hospitalization for heart failure in patients with previous cardiovascular disease. Positive renal outcomes were also shown with empagliflozin. Mostly reported adverse events are genital mycotic infections, while urinary tract infections and events linked to volume depletion are rather rare. Concern about a risk of ketoacidosis and bone fractures has been recently raised, which deserves caution and further evaluation. PMID:27541294

    2007-08-01

    A disproportionate number of African-American men and women are affected by obesity and diabetes. The documented rate of poor glycemic control in the African-American population may contribute to the high rate of morbidity and mortality due to diabetes observed in these patients. Since the benefits of strict glycemic control have been demonstrated in multiple large trials, the aim of treatment should be to achieve the goals set forth by the American Diabetes Association. Insulin remains an essential therapeutic agent for helping patients achieve glycemic control and preventing long-term comorbidities. However, barriers to insulin therapy exist for both the physician and patient. Strategies to counter this resistance include identifying barriers to treatment, restoring the patient's sense of control, utilizing simple regimens, and reviewing the benefits of insulin and the risk of hypoglycemia. In treating African-American patients with diabetes, providers of various racial and ethnic backgrounds may maximize treatment efficacy by attempting to understand and practice culturally competent care.

    Bisphosphonates are the mainstay of osteoporosis treatment but also play a fundamental role in treating other bone diseases such as Osteogenesis Imperfecta, Pagets' disease, and in the prevention of adverse skeletal effects in certain cancers such as prostate cancer or multiple myeloma. In the last decades, the refinement of bisphosphonates and an increase in the number of new bisphosphonates commercialized has altered the clinical management of these diseases. Despite differences between randomized controlled trials and observational studies, overall all bisphosphonates licensed have proven to reduce the risk of fracture through the inhibition of bone resorption. Other beneficial effects include pain reduction in bone metastasis and potentially a decrease in mortality. However, the chronic nature of most of these disorders implies long-term treatments, which can be associated with long-term adverse effects. Some of the adverse effects identified include an increased risk of atypical femur fractures, osteonecrosis of the jaw, gastrointestinal side effects, or atrial fibrillation. The harm/benefit thinking and the constant update regarding these medications are vital in the day-to-day decision-making in clinical practices. The aims of this review are to compile the basic characteristics of these drugs and outline the most important benefits and side effects and provide a clinical context as well as a research agenda to fill the gaps in our knowledge.

    2013-09-01

    Diabetes mellitus, especially type 2, is a metabolic disease involving the coexistence of several cardiovascular risk factors. Affected patients are therefore at high cardiovascular risk (2-3 times higher than that of men in the general population and 2-6 times higher than that of women). Cardiovascular disease is the main cause of death in the diabetic population, followed by cancer. Cardiovascular risk cannot be compared between diabetic patients and persons who have already shown one or more manifestations of cardiovascular disease (such as myocardial infarction). Single risk factors should be evaluated in combination with other risk factors and a person's cardiovascular risk should be individually assessed. Cardiovascular risk assessment in patients with diabetes through current calculations methods is complex because their ability to predict risk in individuals is very low. Studies such as that by Steno have demonstrated the validity of a comprehensive strategy to control all the risk factors present in persons with type 2 diabetes mellitus, which can reduce the development of micro- and macrovascular complications and mortality by almost 50%. The present article reviews each of the classical cardiovascular risk factors (hypertension, dyslipidemia, smoking, obesity, sedentariness) in relation to diabetes, as well as their recommended targets and the benefits of their control. In view of the above, a comprehensive approach is recommended to control the multiple risk factors that can coexist in persons with type 2 diabetes mellitus. PMID:24444518

The slow titration often delays time to therapeutic response. This raises the question of whether, in some patients, it may be safe to use a more rapid clozapine titration. The following case illustrates the potential risks associated with the use of multiple antipsychotics and rapid clozapine titration. We present the case of a young man with schizophrenia who developed life threatening neuroleptic malignant syndrome (NMS) during rapid clozapine titration and treatment with multiple antipsychotics. We were unable to find another case in the literature of NMS associated with rapid clozapine titration. This case is meant to urge clinicians to carefully evaluate the risks and benefits of rapid clozapine titration, and to encourage researchers to further evaluate the safety of rapid clozapine titration. Rapid clozapine titration has implications for decreasing health care costs associated with prolonged hospitalizations, and decreasing the emotional suffering associated with uncontrolled symptoms of psychosis. Clozapine is considered the most effective antipsychotic available thus efforts should focus on developing strategies that would allow for safest and most efficient use of clozapine to encourage its utilization for treatment resistance schizophrenia.

    The association between diabetes and the risk of developing dementia has received much attention in epidemiological studies. An accurate population-based prospective cohort study has been conducted in the elderly population of the town of Hisayama in Japan since 1985 aiming to elucidate the secular trends in the prevalence of dementia and examine risk and protective factors for dementia in the Japanese population. The prevalence of all-cause dementia significantly increased from 1985 to 2012. In regard to subtypes of dementia, a similar trend was observed for Alzheimer's disease (AD). In a prospective study of risk factors for dementia in Hisayama elder residents without dementia, diabetes was identified as a significant risk factor for developing all-cause dementia, especially AD. Moreover, 2-hour post-load glucose levels were closely associated with increased risk of all-cause dementia, AD, and vascular dementia. In a pathological study of Hisayama residents, higher levels of 2-hour post-load glucose, fasting insulin, and homeostasis model assessment of insulin resistance (HOMA-IR) were significantly associated with increased risk of neuritic plaques. The steep increase in the frequency of diabetes could lead to the increasing trend in the prevalence of dementia, especially AD, in the Japanese elderly. PMID:27395456

  7. Seafood: nutritional benefits and risk aspects.

    Seafood, such as fish, crustacean and molluscan shellfish, and echinoderms, provides in the edible part (e. g., filet, abdominal muscle) many nutritional components beneficial for the human diet like n-3 polyunsaturated long chain fatty acids (PUFAs), namely eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), essential elements such as selenium and iodine, high potassium and low sodium concentrations, and the vitamins D, A, E, and B(12), as well as taurine (2-aminoethanesulfonic acid) among others. Its protein is highly digestible due to low connective tissue content, and cholesterol content is also low in fish. Lean fish species are extremely low in fat content (<1 %), while fatty species are extremely rich in PUFAs. However, being subject to environmental influences from its habitat, seafood also entails water-borne health risks such as organic pollutants, toxins, parasites, and heavy metals. Nevertheless, the vast majority of experimental and epidemiological studies have proven that the benefits of fish intake exceed the potential risks even for vulnerable consumer groups. PMID:23258397

    Classical paper-and-pencil based risk assessment questionnaires are often accompanied by the online versions of the questionnaire to reach a wider population. This study focuses on the loss, especially in risk estimation performance, that can be inflicted by direct transformation from the paper to online versions of risk estimation calculators by ignoring the possibilities of more complex and accurate calculations that can be performed using the online calculators. We empirically compare the risk estimation performance between four major diabetes risk calculators and two, more advanced, predictive models. National Health and Nutrition Examination Survey (NHANES) data from 1999–2012 was used to evaluate the performance of detecting diabetes and pre-diabetes. American Diabetes Association risk test achieved the best predictive performance in category of classical paper-and-pencil based tests with an Area Under the ROC Curve (AUC) of 0.699 for undiagnosed diabetes (0.662 for pre-diabetes) and 47% (47% for pre-diabetes) persons selected for screening. Our results demonstrate a significant difference in performance with additional benefits for a lower number of persons selected for screening when statistical methods are used. The best AUC overall was obtained in diabetes risk prediction using logistic regression with AUC of 0.775 (0.734) and an average 34% (48%) persons selected for screening. However, generalized boosted regression models might be a better option from the economical point of view as the number of selected persons for screening of 30% (47%) lies significantly lower for diabetes risk assessment in comparison to logistic regression (p < 0.001), with a significantly higher AUC (p < 0.001) of 0.774 (0.740) for the pre-diabetes group. Our results demonstrate a serious lack of predictive performance in four major online diabetes risk calculators. Therefore, one should take great care and consider optimizing the online versions of questionnaires that were

    The latter half of the twentieth century has witnessed rapid advances in cardiovascular epidemiology and medicine. Concurrently, secular trends in lifestyle practices and general improvements in standards of living have resulted in several alarming trends for cardiovascular disease prevention and health promotion. The adoption of unhealthy dietary patterns, growing socio-economic and racial disparities in chronic disease prevalence, low levels of physical activity, and other as yet unidentified genetic and environmental determinants have led to burgeoning rates of both pediatric and adult obesity and diabetes mellitus. Women appear to be at particular risk as the gender advantage for coronary heart disease (CHD) is counterbalanced by an increased incidence of obesity and diabetes. In order to further examine these complex associations, we review the available epidemiological data regarding the impact of obesity and diabetes on cardiovascular health in women. PMID:12478201

    Cardiovascular complications remain the leading causes of morbidity and premature mortality in patients with diabetes mellitus. Studies in humans and preclinical models demonstrate lasting gene expression changes in the vasculopathies initiated by previous exposure to high glucose concentrations and the associated overproduction of reactive oxygen species. The molecular signatures of chromatin architectures that sensitize the genome to these and other cardiometabolic risk factors of the diabetic milieu are increasingly implicated in the biological memory underlying cardiovascular complications and now widely considered as promising therapeutic targets. Atherosclerosis is a complex heterocellular disease where the contributing cell types possess distinct epigenomes shaping diverse gene expression. Although the extent that pathological chromatin changes can be manipulated in human cardiovascular disease remains to be established, the clinical applicability of epigenetic interventions will be greatly advanced by a deeper understanding of the cell type-specific roles played by writers, erasers, and readers of chromatin modifications in the diabetic vasculature. This review details a current perspective of epigenetic mechanisms of macrovascular disease in diabetes mellitus and highlights recent key descriptions of chromatinized changes associated with persistent gene expression in endothelial, smooth muscle, and circulating immune cells relevant to atherosclerosis. Furthermore, we discuss the challenges associated with pharmacological targeting of epigenetic networks to correct abnormal or deregulated gene expression as a strategy to alleviate the clinical burden of diabetic cardiovascular disease.

    Identity formation constitutes a core developmental task during adolescence, but may be challenged when having a chronic illness such as type 1 diabetes. The present study examined whether viewing positive benefits to one's diabetes across adolescence was related to greater identity exploration and commitment later in time. A total of 55 adolescents (10-14 years; 47% female) with type 1 diabetes participated in a six-wave study spanning 3 years (with six-month measurement intervals). Through latent growth curve modeling, Time 6 identity scores were regressed on intercept and slope terms of benefit finding through Times 1-4, simultaneously controlling for demographic and clinical variables. Identity exploration (but not commitment) at Time 6 was positively predicted by the intercept and slope of benefit finding: adolescents who find benefits in diabetes are more inclined to explore different alternatives later on in adolescence. Benefit finding may constitute a resource facilitating identity formation in adolescents with diabetes. PMID:26999440

    2013-01-01

    Background To test whether equivalent energy expenditure by moderate-intensity (e.g., walking) and vigorous-intensity exercise (e.g., running) provides equivalent health benefits. Methods and Results We used the National Runners’ (n=33,060) and Walkers’ (n=15,945) Health Study cohorts to examine the effect of differences in exercise mode and thereby exercise intensity on coronary heart disease (CHD) risk factors. Baseline expenditure (METhr/d) was compared to self-reported, physician-diagnosed incident hypertension, hypercholesterolemia, diabetes and CHD during 6.2 years follow-up. Running significantly decreased the risks for incident hypertension by 4.2% (P<10-7), hypercholesterolemia by 4.3% (P<10-14), diabetes by 12.1% (P<10-5), and CHD by 4.5% per METh/d run (P=0.05). The corresponding reductions for walking were 7.2% (P<10-6), 7.0% (P<10-8), 12.3% (P<10-4), and 9.3% (P=0.01). Relative to <1.8 METh/d, the risk reductions for 1.8 to 3.6, 3.6 to 5.4, 5.4 to 7.2, and ≥ 7.2 METh/d were: 1) 10.1%, 17.7%, 25.1% and 34.9% from running and 14.0%, 23.8%, 21.8% and 38.3% from walking for hypercholesterolemia; 2) 19.7%, 19.4%, 26.8% and 39.8% from running and 14.7%, 19.1%, 23.6% and 13.3% from walking for hypertension; 3) 43.5%, 44.1%, 47.7% and 68.2% from running and 34.1%, 44.2%, and 23.6% from walking for diabetes (too few cases for diabetes for walking >5.4 METh/d). The risk reductions were not significantly greater for running than walking for diabetes (P=0.94) or CHD (P=0.26), and only marginally greater for walking than running for hypertension (P=0.06) and hypercholesterolemia (P=0.04). Conclusion Equivalent energy expenditures by moderate (walking) and vigorous (running) exercise produced similar risk reductions for hypertension, hypercholesterolemia, diabetes, and CHD, but there is limited statistical power to evaluate CHD conclusively.

    Purpose Androgen deprivation therapy may increase diabetes risk. As the benefits of primary androgen deprivation therapy for localized prostate cancer are controversial, and most prostate cancer survivors are of advanced age with comorbidities, it is important to determine if primary androgen deprivation therapy increases the risk of diabetes and to determine the susceptibility factors. Materials and Methods We conducted a retrospective cohort study of 12,191 men diagnosed with incident localized prostate cancer during 1995 to 2008, age 35 to 100 years, and without diabetes or receipt of prostatectomy or radiation 1 year after diagnosis. Patients were enrolled in 1 of 3 managed health plans and followed through 2010. Primary androgen deprivation therapy was defined as androgen deprivation therapy within 1 year after diagnosis. Incident diabetes was ascertained using inpatient and outpatient diagnosis codes, diabetes medications and hemoglobin A1c values. We estimated primary androgen deprivation therapy associated diabetes risk using Cox proportional hazard models in conventional and propensity score analyses. Results Diabetes developed in 1,203 (9.9%) patients during followup (median 4.8 years) with incidence rates of 2.5 and 1.6 events per 100 person-years in the primary androgen deprivation therapy and nonprimary androgen deprivation therapy groups, respectively. Primary androgen deprivation therapy was associated with a 1.61-fold increased diabetes risk (95% CI 1.38–1.88). The number needed to harm was 29. The association was stronger in men age 70 or younger than in older men (HR 2.25 vs 1.40, p value for interaction = 0.008). Conclusions Primary androgen deprivation therapy may increase diabetes risk by 60% and should be used with caution when managing localized prostate cancer. Because of the consistent association between androgen deprivation therapy and greater diabetes risk across disease states, we recommend routine screening and lifestyle

    Benefit-risk assessment in medicine has been a valuable tool in the regulation of medicines since the 1960s. Benefit-risk assessment takes place in multiple stages during a medicine's life-cycle and can be conducted in a variety of ways, using methods ranging from qualitative to quantitative. Each benefit-risk assessment method is subject to its own specific strengths and limitations. Despite its widespread and long-time use, benefit-risk assessment in medicine is subject to debate and suffers from a number of limitations and is currently still under development. This state of the art review paper will discuss the various aspects and approaches to benefit-risk assessment in medicine in a chronological pathway. The review will discuss all types of benefit-risk assessment a medicinal product will undergo during its lifecycle, from Phase I clinical trials to post-marketing surveillance and health technology assessment for inclusion in public formularies. The benefit-risk profile of a drug is dynamic and differs for different indications and patient groups. In the end of this review we conclude benefit-risk analysis in medicine is a developed practice that is subject to continuous improvement and modernisation. Improvement not only in methodology, but also in cooperation between organizations can improve benefit-risk assessment. PMID:21683115

    A recent increase in the incidence of diabetes and pre-diabetes is causing many employers to spend more of their healthcare benefit budgets to manage the conditions. A self-insured university in the USA has implemented an interprofessional diabetes mellitus risk reduction program using its own employee faculty and staff experts to help fellow employees manage their diabetes and pre-diabetes. The interprofessional team consists of five pharmacists, a dietitian, an exercise physiologist, a health educator and a licensed mental health practitioner. In addition, the participant's physician serves as a consultant to the program, as does a human resources healthcare benefits specialist and a wellness coordinator. The volunteer program takes place at the worksite during regular business hours and is free of charge to the employees. The faculty and staff delivering the program justify the cost of their time through an interprofessional educational model that the program will soon provide to university students. PMID:22957897

    Objective Psoriasis is a common chronic inflammatory disorder that has been mechanistically linked to type II diabetes mellitus. We sought to assess the risk of incident diabetes in patients with psoriasis and to evaluate diabetes treatment patterns among patients with psoriasis and incident diabetes. Design Population-based cohort study. Setting UK-based electronic medical records. Patients We matched 108,132 psoriasis patients aged 18–90 years to 430,716 unexposed patients based on practice and time of visit. For our nested study, only patients who developed incident diabetes during our study time were included. Main Outcome Measure(s) Incident diabetes and adjusted risk of pharmacotherapy among those with incident diabetes. Results The fully adjusted HRs (95% CI) for incident diabetes were 1.14 (1.10–1.18), 1.11 (1.07, 1.15), and 1.46 (1.30, 1.65) in the overall, mild and severe psoriasis groups, respectively. Among those with incident diabetes and severe psoriasis, the adjusted risk for receiving diabetes pharmacotherapy was 1.55 (1.15–2.10). Conclusions Our results suggest that psoriasis is an independent risk factor for the development of type II diabetes mellitus in a dose dependent manner, and that patients with severe psoriasis who develop diabetes are more likely to receive systemic diabetic therapies in comparison to diabetics without psoriasis.

    PubMed

    The heart and vascular system are susceptible to the harmful effects of alcohol. Alcohol is an active toxin that undergoes widespread diffusion throughout the body, causing multiple synchronous and synergistic effects. Alcohol consumption decreases myocardial contractility and induces arrhythmias and dilated cardiomyopathy, resulting in progressive cardiovascular dysfunction and structural damage. Alcohol, whether at binge doses or a high cumulative lifetime consumption-both of which should be discouraged-is clearly deleterious for the cardiovascular system, increasing the incidence of total and cardiovascular mortality, coronary and peripheral artery disease, heart failure, stroke, hypertension, dyslipidaemia, and diabetes mellitus. However, epidemiological, case-control studies and meta-analyses have shown a U-type bimodal relationship so that low-to-moderate alcohol consumption (particularly of wine or beer) is associated with a decrease in cardiovascular events and mortality, compared with abstention. Potential confounding influences-alcohol-dose quantification, tobacco use, diet, exercise, lifestyle, cancer risk, accidents, and dependence-can affect the results of studies of both low-dose and high-dose alcohol consumption. Mendelian methodological approaches have led to doubts regarding the beneficial cardiovascular effects of alcohol, and the overall balance of beneficial and detrimental effects should be considered when making individual and population-wide recommendations, as reductions in alcohol consumption should provide overall health benefits.

    Risk-taking is normal in everyday life if there are associated (perceived) benefits. Benefit-Risk Analysis (BRA) compares the risk of a situation to its related benefits and addresses the acceptability of the risk. Over the past years BRA in relation to food and food ingredients has gained attention. Food, and even the same food ingredient, may confer both beneficial and adverse effects. Measures directed at food safety may lead to suboptimal or insufficient levels of ingredients from a benefit perspective. In BRA, benefits and risks of food (ingredients) are assessed in one go and may conditionally be expressed into one currency. This allows the comparison of adverse and beneficial effects to be qualitative and quantitative. A BRA should help policy-makers to make more informed and balanced benefit-risk management decisions. Not allowing food benefits to occur in order to guarantee food safety is a risk management decision much the same as accepting some risk in order to achieve more benefits. BRA in food and nutrition is making progress, but difficulties remain. The field may benefit from looking across its borders to learn from other research areas. The BEPRARIBEAN project (Best Practices for Risk-Benefit Analysis: experience from out of food into food; http://en.opasnet.org/w/Bepraribean) aims to do so, by working together with Medicines, Food Microbiology, Environmental Health, Economics & Marketing-Finance and Consumer Perception. All perspectives are reviewed and subsequently integrated to identify opportunities for further development of BRA for food and food ingredients. Interesting issues that emerge are the varying degrees of risk that are deemed acceptable within the areas and the trend towards more open and participatory BRA processes. A set of 6 'state of the art' papers covering the above areas and a paper integrating the separate (re)views are published in this volume. PMID:21679738

    Background— Maternal diabetes mellitus is associated with an increased risk of offspring congenital heart defects (CHD); however, the causal mechanism is poorly understood. We further investigated this association in a Danish nationwide cohort. Methods and Results— In a national cohort study, we identified 2 025 727 persons born from 1978 to 2011; among them were 7296 (0.36%) persons exposed to maternal pregestational diabetes mellitus. Pregestational diabetes mellitus was identified by using the National Patient Register and individual-level information on all prescriptions filled in Danish pharmacies. Persons with CHD (n=16 325) were assigned to embryologically related cardiac phenotypes. The CHD prevalence in the offspring of mothers with pregestational diabetes mellitus was 318 per 10 000 live births (n=232) in comparison with a baseline risk of 80 per 10 000; the adjusted relative risk for CHD was 4.00 (95% confidence interval, 3.51–4.53). The association was not modified by year of birth, maternal age at diabetes onset, or diabetes duration, and CHD risks associated with type 1 (insulin-dependent) and type 2 (insulin-independent) diabetes mellitus did not differ significantly. Persons born to women with previous acute diabetes complications had a higher CHD risk than those exposed to maternal diabetes mellitus without complications (relative risk, 7.62; 95% confidence interval, 5.23–10.6, and relative risk, 3.49; 95% confidence interval, 2.91–4.13, respectively; P=0.0004). All specific CHD phenotypes were associated with maternal pregestational diabetes mellitus (relative risk range, 2.74–13.8). Conclusions— The profoundly increased CHD risk conferred by maternal pregestational diabetes mellitus neither changed over time nor differed by diabetes subtype. The association with acute pregestational diabetes complications was particularly strong, suggesting a role for glucose in the causal pathway. PMID:27166384

    Institutional review boards (IRBs) are responsible for weighing the risks and benefits of research participation. Qualitative researchers note numerous instances where IRB ethical frameworks fail to align with the ethics of their research projects and point out that IRB understandings of the benefits and risks of research often differ from those of the participants they seek to protect. This qualitative cross-case research investigates participants' interview experiences in six qualitative studies that differed in their methods, subject of focus, and populations. Our findings indicate that contemporary IRBs' use of population "vulnerability" and topic "sensitivity" to assess project risk does not adequately determine the benefits, risks, or ethicality of research. We recommend that IRBs treat as real the evidence for benefits in qualitative research, recognize that sensitivity and vulnerability do not predict risk, and encourage researchers to attend to relationships in their projects.

    Background The purpose of this article is to examine the extent to which cancer clinical trial participants assess the benefits and risks of research participation before enrollment. Methods One hundred and ten oncology research participants enrolled in cancer clinical research in a large Northeastern cancer center responded to a self-administered questionnaire on perceptions about cancer clinical trials. Results Of the participants, 51.6% reported they did not directly assess the benefits or risks. Educational level, age, employment, treatment options, insurance, and spiritual–religious beliefs were significantly associated with whether participants assessed risk and benefits. Those who felt well informed were more likely to have assessed the benefits and risks at enrollment than those who did not feel well informed (odds ratio [OR] = 3.92, p = .014); of those who did not assess the risks and benefits, 21% did not feel well informed at enrollment (p = .001). Those who agreed that the clinical trial helped pay the costs of the care had nearly three times the odds of not assessing risks and benefits compared to those who disagreed. Conclusion Our findings have important implications for understanding the role of assessing risks and benefits in the research participation decisions of patients with cancer and call for further understanding of why participants are not assessing information believed to be essential for autonomous informed decisions.

We investigated these in the Prospective Comparison of ARNI With ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure (PARADIGM-HF) trial. Methods and Results— We examined clinical outcomes in 8399 patients with heart failure and reduced ejection fraction according to history of diabetes mellitus and glycemic status (baseline hemoglobin A1c [HbA1c]: <6.0% [<42 mmol/mol], 6.0%–6.4% [42–47 mmol/mol; pre–diabetes mellitus], and ≥6.5% [≥48 mmol/mol; diabetes mellitus]), in Cox regression models adjusted for known predictors of poor outcome. Patients with a history of diabetes mellitus (n=2907 [35%]) had a higher risk of the primary composite outcome of heart failure hospitalization or cardiovascular mortality compared with those without a history of diabetes mellitus: adjusted hazard ratio, 1.38; 95% confidence interval, 1.25 to 1.52; P<0.001. HbA1c measurement showed that an additional 1106 (13% of total) patients had undiagnosed diabetes mellitus and 2103 (25%) had pre–diabetes mellitus. The hazard ratio for patients with undiagnosed diabetes mellitus (HbA1c, >6.5%) and known diabetes mellitus compared with those with HbA1c<6.0% was 1.39 (1.17–1.64); P<0.001 and 1.64 (1.43–1.87); P<0.001, respectively. Patients with pre–diabetes mellitus were also at higher risk (hazard ratio, 1.27 [1.10–1.47]; P<0.001) compared with those with HbA1c<6.0%. The benefit of LCZ696 (sacubitril/valsartan) compared with enalapril was consistent across the range of HbA1c in the trial. Conclusions— In patients with heart failure and reduced ejection fraction, dysglycemia is common and pre–diabetes mellitus is associated with a higher risk of adverse cardiovascular outcomes (compared with patients with no diabetes mellitus and HbA1c <6.0%). LCZ696 was beneficial compared with enalapril

    Background & Aims Anti-diabetic drugs have been found to have various effects on cancer in experimental systems and in epidemiological studies, although the association between these therapeutics and the risk of human pancreatic cancer has not been explored. We investigated the effect of anti-diabetic therapies on the risk of pancreatic cancer. Methods A hospital-based, case-control study was conducted at M.D. Anderson Cancer Center from 2004 through 2008 involving 973 patients with pancreatic adenocarcinoma (including 259 diabetics) and 863 controls (including 109 diabetics). Information on diabetes history and other risk factors was collected by personal interview. The frequencies of use of insulin, insulin secretagogues, thiazolidinediones, metformin and other antidiabetic medications among diabetics were compared between cases and controls. The risk of pancreatic cancer was estimated using unconditional logistic regression analysis. Results Diabetics that had taken metformin had a significantly lower risk of pancreatic cancer, compared with those that had not taken metformin (OR=0.38; 95% CI, 0.22–0.69; P=0.001) with adjustments for demographic, clinical and risk factors. This difference remained statistically significant when the analysis was restricted to patients with a duration of diabetes >2 years or those never used insulin. In contrast, diabetics that had taken insulin or insulin secretagogues had a significantly higher risk of pancreatic cancer, compared with diabetics that had not take these drugs. Use of thiazolidinediones did not significantly modify pancreatic cancer risk. Conclusions Metformin use was associated with reduced risk, and insulin or insulin secretagogues use were associated with increased risk of pancreatic cancer in diabetics. PMID:19375425

    Obesity is not a cosmetic or social issue; it is an animal health issue. The metabolic effects of obesity on insulin resistance and development of hyperlipidemia and the mechanical stress excess weight places on the musculoskeletal system are well established in the literature. Additional health risks from obesity, such as fatty accumulation in the liver, intestinal bacterial dysbiosis, and changes to renal architecture, are less well understood, but have been demonstrated to occur clinically in obese animals and may lead to deleterious long-term health effects. Keeping dogs and cats lean lowers their risk for development of certain diseases and leads to a longer and better quality of life. PMID:27267439

    The ecological risk assessment process in its ideal form is an unbiased approach for assessing the probability of harm to the environment as a consequence of a given action. This information can then be combined with other societal values and biases in the management of such risks. However, as the process currently is understood, decision makers often are accused of manipulating information in order to generate decisions or achieve buy in from the public in support of a particular political agenda. A clear understanding of the nature of the risk management process can help define areas where information should be free from social or personal bias, and areas where values and judgments are critical. The authors do not propose to discuss the individual`s decision-making process, but rather to address the social process of risk communication and environmentally-related decision-making, identifying which parts of that process require bias-free, scientifically generated information about the consequences of various actions and which parts need an understanding of the social values which underlie the informed choices among those possible actions.

    ABSTRACT Ever since the successful Apollo 11 Moon landing in 1969, a “moonshot” has come to signify a bold effort to achieve a seemingly impossible task. The Obama administration recently called for a moonshot to cure cancer, an initiative that has elicited mixed responses from researchers who welcome additional funding but worry about raising expectations. We suggest that a successful moonshot requires a sufficient understanding of the basic science underlying a problem in question so that efforts can be focused on engineering a solution. Current gaps in our basic knowledge of cancer biology make the cancer moonshot a uniquely challenging endeavor. Nevertheless, history has shown that intensive research efforts have frequently yielded conceptual and technological breakthroughs with unanticipated benefits for society. We expect that this effort will be no different. PMID:27578761

    Cancer is the second cause of death. Association of diabetes as a growing and costly disease with cancer is a major health concern. Meanwhile, preexisting diabetes is associated with an increased risk of all-cause and cancer-specific mortalities. Presence of diabetes related comorbidities, poorer response to cancer treatment, and excess mortality related to diabetes are among the most important explanations. Although diabetes appear to be a risk factor for cancer and is associated with the mortality risk in cancer patients, several factors such as diabetes duration, multiple drug therapy, and the presence of diabetes comorbidities make the assessment of the effect of diabetes treatment on cancer risk and mortality difficult. Metformin is the drug of choice for the treatment of type 2 diabetes. The available evidence from basic science, clinical, and population-based research supports the anticancer effect of metformin. However, randomized controlled clinical trials do not provide enough evidence for a strong protective effect of metformin on cancer incidence or mortality. One of the most important limitations of these trials is the short duration of the followup. Further long-term randomized controlled clinical trials specifically designed to determine metformin effect on cancer risk are needed to provide the best answer to this challenge. PMID:24224094

    The world population comprises of 23% Muslims. Ramadan is the holy month of the Islamic year during which all healthy Muslims observe fasts. Although children and sick people are exempted from fasting but many of this group, want to observe fasts despite the medical advice against it. This includes a subset of people with diabetes which carries a considerable risk. Hypoglycaemia and hyperglycaemia are among the main hazards. Majority of Muslims with diabetes can fast safely during Ramadan; However some are placed at a greater risk. Pre-Ramadan risk assessment, structured education and selection of appropriate medication has shown to minimize the risks associated with fasting among people with diabetes. PMID:26013777

    The introduction of second generation antidepressants, such as mianserin and nomifensine, was prompted by the desire to produce drugs which were safer, had fewer side-effects and were faster acting than the tricyclics. A brief review of the data on mianserin and nomifensine is presented in relation to these aims. Some advantages for the new drugs can be claimed and the risks of severe adverse effects relating to blood dyscrasias in the case of mianserin, and fever in the case of nomifensine, appear outweighed by the therapeutic gains.

    Studies of fish consumption often focus on awareness of and adherence to advisories, how much fish people eat, and contaminant levels in those fish. This paper examines knowledge and accuracy of risks and benefits of fish consumption among fishers and other recreationists in the New York Bight, indicative of whether they could make sound dietary decisions. While most respondents knew about health risks (70%) and benefits (94%) of consuming fish, far fewer could name specific risks and benefits. Less than 25% of respondents mentioned mercury and less than 15% mentioned that pregnant women and children were at risk. Far fewer people mentioned polychlorinated biphenyls (PCBs). Nearly 70% said it was healthy to eat fish, and 45% were aware that fish were rich in healthful oils. Despite the lack of details about what specific risks and benefits of fish, well over a third did not feel they needed more information. Other respondents had basic questions, but did not pose specific questions about the fish they caught or ate that would have clarified their individual risk-balancing decisions. Knowledge of which fish were high in contaminants did not match the mercury or PCB levels in those fish. There was a disconnect between the information base about specific risks and benefits of fish consumption, levels of mercury and PCBs in fish, and the respondent’s desire for more information. These data indicate that respondents did not have enough accurate information about contaminants in fish to make informed risk-balancing decisions. PMID:19193369

    The contribution of exposure to persistent organic pollutants (POPs) to the incidence of diabetes has received little attention until recently. A number of reports have emerged, however, concerning elevated diabetes in persons occupationally exposed to dioxin. United States (US) Air Force personnel in Vietnam who sprayed Agent Orange containing dioxin as a contaminant had elevated rates of diabetes, leading to US government compensation for diabetes in these veterans. Recent studies in populations exposed to polychlorinated biphenyls (PCBs) and chlorinated pesticides found a dose-dependent elevated risk of diabetes. An elevation in risk of diabetes in relation to levels of several POPs has been demonstrated by two different groups using the National Health and Nutrition Examination Survey (NHANES), a random sampling of US citizens. The strong associations seen in quite different studies suggest the possibility that exposure to POPs could cause diabetes. One striking observation is that obese persons that do not have elevated POPs are not at elevated risk of diabetes, suggesting that the POPs rather than the obesity per se is responsible for the association. Although a specific mechanism is not known, most POPs induce a great number and variety of genes, including several that alter insulin action. Because diabetes is a dangerous disease that is increasing in frequency throughout the world, further study of the possibility that exposure to POPs contributes to the etiology of diabetes is critical.

    While the number of women in developed countries who plan a home birth is low, the number has increased over the past decade in the US, and there is evidence that more women would choose this option if it were readily available. Rates of planned home birth range from 0.1% in Sweden to 20% in the Netherlands, where home birth has always been an integrated part of the maternity system. Benefits of planned home birth include lower rates of maternal morbidity, such as postpartum hemorrhage, and perineal lacerations, and lower rates of interventions such as episiotomy, instrumental vaginal birth, and cesarean birth. Women who have a planned home birth have high rates of satisfaction related to home being a more comfortable environment and feeling more in control of the experience. While maternal outcomes related to planned birth at home have been consistently positive within the literature, reported neonatal outcomes during planned home birth are more variable. While the majority of investigations of planned home birth compared with hospital birth have found no difference in intrapartum fetal deaths, neonatal deaths, low Apgar scores, or admission to the neonatal intensive care unit, there have been reports in the US, as well as a meta-analysis, that indicated more adverse neonatal outcomes associated with home birth. There are multiple challenges associated with research designs focused on planned home birth, in part because conducting randomized controlled trials is not feasible. This report will review current research studies published between 2004 and 2014 related to maternal and neonatal outcomes of planned home birth, and discuss strengths, limitations, and opportunities regarding planned home birth.

    Recent studies reported that smoking cessation leads to higher short-term risk of type 2 diabetes than continuing to smoke. However, the duration of increased diabetes risk following smoking cessation needs further investigation. We followed 135,906 postmenopausal women aged 50–79 years enrolled in the Women's Health Initiative between September 1, 1993, and December 31, 1998, over an average of 11 years to examine the association between smoking cessation and risk of diabetes using Cox proportional hazard multivariable-adjusted regression models. Compared with that for never smokers, the risk for diabetes was significantly elevated in current smokers (hazard ratio = 1.28, 95% confidence interval: 1.20, 1.36) but was even higher in women who quit smoking during the first 3 years of follow-up (hazard ratio = 1.43, 95% confidence interval: 1.26, 1.63). Among former smokers, the risk of diabetes decreased significantly as the time since quitting increased and was equal to that of never smokers following a cessation period of 10 years. In new quitters with low cumulative exposure (<20 pack-years), diabetes risk was not elevated following smoking cessation. In conclusion, the risk of diabetes in former smokers returns to that in never smokers 10 years after quitting, and even more quickly in lighter smokers. PMID:23817918

    Purpose The purpose of this study was to evaluate whether any stage of diabetic retinopathy (DR) is associated with levels of plasma erythropoietin and other plasma parameters. Methods It was examined a representative sample of 180 type 2 diabetes patients aged 40 to 79 years. Ophthalmic examination including a funduscopic examination, performed by an experienced ophthalmologist and the retinal finding were classified according to the grading system for diabetic retinopathy of ETDRS (Early Treatment Diabetic Retinopathy Study). It was measured the levels of plasma erythropoietin, cholesterol, triglyceride, apolipoproteins A and B, C-reactive protein, fasting blood glucose and hemoglobin A1C (HbA1C) in 88 DR patients and 92 controls without DR. Risk factors correlated with DR were compared between groups. Results The study group of 180 patients included 72 males and 108 females. The mean age of the patients with and without DR was 57.36 ± 8.87 years and 55.33 ± 8.28 years, respectively. Of the 88 patients with DR, only 9 (10%) had proliferative DR and the rest suffered from non-proliferative DR. The mean plasma levels of erythropoietin in proliferative DR group showed a significant difference in comparison to other groups. The mean plasma levels of cholesterol, triglyceride, apolipoproteins A and B, C-reactive protein, and fasting blood glucose were not significantly different in the three groups except for HbA1C. The absolute relative risk (ARR) also showed that erythropoietin was an increasing risk for proliferative DR (ARR, 1.17; 95% confidence interval, 1.060 to 1.420; odds ratio,1.060). Conclusions Of the factors studied, erythropoietin level showed significant increase in proliferative DR group. The stepwise raised in mean plasma erythropoietin level which demonstrates significant correlation with proliferative DR versus remaining two groups, will be an indication of its role in proliferative DR.

    Plant proteins have a reduced content of essential amino acids in comparison to animal proteins. A significant reduction of limiting amino acids (methionine, lysine, tryptophan) means lower protein synthesis. In subjects with predominant or exclusive consumption of plant food a higher incidence of hypoproteinemia due to significant reduction of methionine and lysine intakes was observed. On the other hand, lower intake of these amino acids provides a preventive effect against cardiovascular disease via cholesterol regulation by an inhibited hepatic phospholipid metabolism. Vegetarians have a significantly higher intake of non-essential amino acids arginine and pyruvigenic amino acids glycine, alanine, serine. When plant protein is high in non-essential amino acids, down-regulation of insulin and up-regulation of glucagon is a logical consequence. The action of glucagon in the liver is mediated by stimulation of adenyl cyclase that raises cyclic-AMP (adenosine-3,5-monophosphate) concentrations. Cyclic-AMP down-regulates the synthesis of a number of enzymes required for de novo lipogenesis and cholesterol synthesis, up-regulates key gluconeogenic enzymes and the LDL receptors and decreases the IGF-1 activity (insulin-like growth factor). Cyclic-AMP thus provides a reduction of atherosclerosis risk factors as well as a retardation of cancer development. A sufficient consumption of plant proteins has the protective effects against chronic degenerative diseases (Tab. 2, Ref. 26). PMID:16201743

    Factors predisposing to perception of repositories as risky include the nuclear track record of secrecy and ineptitude, the overconfidence of some pro-nukes and the premature commercialization of an immature technology. Then, in parallel, we have the AEC-DOE track record including a bureaucratic approach involving premature policy decisions and continual changes in nuclear waste policy as demanded by Congress. The confusion of nuclear power with nuclear weapons is encouraged by those whose goal is to get rid of nuclear power. Media coverge feeds on controversy and a crisis, is a major factor in public perception of N-power and repositories as risky. Beyond their actual physical effects, there is the signal value of accidents such as Browns Ferry, Chernobyl, the Hanford tank leaks, Challenger, and TMI. These accidents have signaled that either the managers and operators don't understand the technology well enough to manage it, or worse yet, that the technology itself may not be manageable. With wodefully inadequate science and technology eduation, US citizens are unprepared to make decisions about management and uses of technology or to conduct their own risk evaluations. All of the above is occurring against the backdrop of the widespread and pervasive decline of trust in government and institutions in the past 25 years. And finally, there is Murphy's Law - everyone has some personal knowledge that whatever can go wrong will go wrong some day. In this social context, the tilt is toward perception of repositories as risky.

    In this review, we explore the concept of 'double diabetes', a combination of type 1 diabetes with features of insulin resistance and type 2 diabetes. After considering whether double diabetes is a useful concept, we discuss potential mechanisms of increased insulin resistance in type 1 diabetes before examining the extent to which double diabetes might increase the risk of cardiovascular disease (CVD). We then go on to consider the proposal that weight gain from intensive insulin regimens may be associated with increased CV risk factors in some patients with type 1 diabetes, and explore the complex relationships between weight gain, insulin resistance, glycaemic control and CV outcome. Important comparisons and contrasts between type 1 diabetes and type 2 diabetes are highlighted in terms of hepatic fat, fat partitioning and lipid profile, and how these may differ between type 1 diabetic patients with and without double diabetes. In so doing, we hope this work will stimulate much-needed research in this area and an improvement in clinical practice. PMID:23613085

    marketing, new UV filters undergo stringent human testing to confirm their efficacy as well as the absence of irritation, sensitization, photoirritation, and photosensitization potential in man. UV filters not only protect against acute skin injury, such as sunburn, but also against long-term and chronic skin damage, including cellular DNA damage, photoinduced immune suppression, and, by extension, skin cancer. The protection provided by modern sunscreens against UV-induced skin cancer was shown in animal photocarcinogenicity studies and confirmed by numerous in vitro, animal, and human investigations: UV filters protect the p53 tumor suppressor gene from damage and prevent UV-induced immune suppression. Recent studies suggest that sunscreens protect against precursor lesions of skin cancer, such as actinic keratoses. Additional benefits of ultraviolet filters include prevention of photodermatoses, such as polymorphic light eruption, and, possibly, photoaging. Modern sunscreens are safe for children and adults. Percutaneous penetration and irritation rates of topically applied substances in children and adults are similar. The principal protective measure is to keep children out of the sun and/or to cover them with protective clothes; however, sunscreens are a safe and effective and often the only feasible defense of children against UV radiation. In conclusion, sunscreens are safe protective devices that undergo stringent safety and efficacy evaluation. PMID:11407932

    Background The risk-benefit ratio of aspirin therapy in prevention of cardiovascular disease (CVD) remains contentious, especially in type 2 diabetes. This study examined the benefit and harm of low-dose aspirin (daily dose < 300 mg) in patients with type 2 diabetes. Methods This is a longitudinal observational study with primary and secondary prevention cohorts based on history of CVD at enrolment. We compared the occurrence of primary composite (non-fatal myocardial infarction or stroke and vascular death) and secondary endpoints (upper GI bleeding and haemorrhagic stroke) between aspirin users and non-users between January 1995 and July 2005. Results Of the 6,454 patients (mean follow-up: median [IQR]: 4.7 [4.4] years), usage of aspirin was 18% (n = 1,034) in the primary prevention cohort (n = 5731) and 81% (n = 585) in the secondary prevention cohort (n = 723). After adjustment for covariates, in the primary prevention cohort, aspirin use was associated with a hazard-ratio of 2.07 (95% CI: 1.66, 2.59, p < 0.001) for primary endpoint. There was no difference in CVD event rate in the secondary prevention cohort. Overall, aspirin use was associated with a hazard-ratio of 2.2 (1.53, 3.15, p < 0.001) of GI bleeding and 1.71 (1.00, 2.95, p = 0.051) of haemorrhagic stroke. The absolute risk of aspirin-related GI bleeding was 10.7 events per 1,000 person-years of treatment. Conclusion In Chinese type 2 diabetic patients, low dose aspirin was associated with a paradoxical increase in CVD risk in primary prevention and did not confer benefits in secondary prevention. In addition, the risk of GI bleeding in aspirin users was rather high. PMID:19878541

    Growing evidence supports that air pollution has become an important risk factor for developing diabetes mellitus. Understanding the contributing effect of air pollution in population studies, elucidating the potential mechanisms involved, and identifying the most responsible pollutants are all required in order to promulgate successful changes in policy and to help formulate preventive measures in an effort to reduce the risk for diabetes. This review summarizes recent findings from epidemiologic studies and mechanistic insights that provide links between exposure to air pollution and a heightened risk for diabetes. PMID:25894943

    1994-10-01

    The number of day care centers in Brazil has doubled over the last few years; with this increase has come a rise in the numbers of cases of communicable disease, particularly pneumonia (the main cause of child mortality in Brazil). A study by Dr. Walter V.C. da Fonseca states that a day care child is 5 times more likely to contact pneumonia. However, since the income earned by women in Brazil today is necessary to meet basic needs, children must be left at home with relatives or sent to day care. Most of the centers taking in children under 6 years of age are urban; they care for, on average, 125-200 children. These children are usually from low income families who live on the outskirts of cities; free day care is only provided to working mothers. There are 3 social factors involved: the greater number of single-parent families, more households supported solely by the mother, and an economic crisis that has hit the poor particularly hard. Financial and administrative responsibility for these centers varies. The centers provide meals, baths, rest, education (including some special education services), and health care (doctors, dentists, and nurses). Some accept abandoned children, who are cared for until they are adopted. However, new studies indicate that the centers represent the primary risk factor for respiratory illnesses and were, until recently, the principal causes of diarrhea and child mortality. An ongoing comparative study by da Fonseca is analyzing the incidence rates of respiratory and infectious diseases among 400 children attending a nursery in Fortaleza in comparison to those for 400 cared for at home by family. Doctor Aluiso Barros, in another study, is observing 1000 children in 40 nurseries in Campinas. For 8 weeks, data was collected on the health, socioeconomic situation, medical history, and family medical history of each child.

    We examined how personal values and perceptions of risks and benefits are associated with the acceptability of nuclear energy (NE). A theoretical model is tested in which beliefs about the risks and benefits of NE mediate the relationship between values and acceptability. The results showed that egoistic values are positively related to the perceived benefits and acceptability of NE. In contrast, altruistic and biospheric values were positively related to the perceived risks of NE. Although it has been argued that NE may help to combat climate change through lower CO(2) emissions, these environmental benefits were not acknowledged by people with strong biospheric values. Furthermore, results confirmed that the more risks respondents perceived, the less they were inclined to accept NE. In contrast, the more a person believed that NE has beneficial consequences, the more acceptable NE was. Finally, as expected, perceived risks and benefits were found to partly mediate the relationship between personal values and acceptability. We discuss the theoretical and practical implications of these findings. PMID:22642255

  19. Health benefits and possible risks of broccoli - an overview.

    Chemopreventive effects of broccoli, a highly valued vegetable, have been known for a long time. Several studies have demonstrated that broccoli might be beneficial by reducing the risk for the development of certain forms of cancer. These effects are generally attributed to glucosinolate-derived degradation products like isothiocyanates and indoles which are formed by the hydrolytic action of plant myrosinase and/or glucosidases deriving from the human microbial flora. However, recent in vitro and experimental animal studies indicate that broccoli, its extracts and the glucosinolate-derived degradation products might also have undesirable effects, especially genotoxic activities. However, the relevance of the genotoxic activities to human health is not known yet. This paper gives an overview on genotoxic, anti-genotoxic/chemopreventive, nutritive and antinutritive properties of broccoli, its ingredients and their degradation products. A qualitative comparison of the benefit and risk of broccoli consumption benefit-risk assessment shows that the benefit from intake in modest quantities and in processed form outweighs potential risks. For other preparations (fortified broccoli-based dietary supplements, diets with extraordinary high daily intake, consumption as a raw vegetable) further studies both for potential risks and beneficial effects are needed in order to assess the benefit and risk in the future.

    Heme oxygenase-1 (HO-1) exerts vasoprotective effects. Such benefit in diabetic vasculopathy, however, remains unclear. We hypothesize that bilirubin mediates HO-1-induced vascular benefits in diabetes. Diabetic db/db mice were treated with hemin (HO-1 inducer) for 2 weeks, and aortas were isolated for functional and molecular assays. Nitric oxide (NO) production was measured in cultured endothelial cells. Hemin treatment augmented endothelium-dependent relaxations (EDRs) and elevated Akt and endothelial NO synthase (eNOS) phosphorylation in db/db mouse aortas, which were reversed by the HO-1 inhibitor SnMP or HO-1 silencing virus. Hemin treatment increased serum bilirubin, and ex vivo bilirubin treatment improved relaxations in diabetic mouse aortas, which was reversed by the Akt inhibitor. Biliverdin reductase silencing virus attenuated the effect of hemin. Chronic bilirubin treatment improved EDRs in db/db mouse aortas. Hemin and bilirubin reversed high glucose-induced reductions in Akt and eNOS phosphorylation and NO production. The effect of hemin but not bilirubin was inhibited by biliverdin reductase silencing virus. Furthermore, bilirubin augmented EDRs in renal arteries from diabetic patients. In summary, HO-1-induced restoration of endothelial function in diabetic mice is most likely mediated by bilirubin, which preserves NO bioavailability through the Akt/eNOS/NO cascade, suggesting bilirubin as a potential therapeutic target for clinical intervention of diabetic vasculopathy.

    Savill, Peter

    2012-01-01

    At present there are nearly 3 million people with diabetes in the UK. It is predicted that this number will almost double by 2025. Nine out of ten of these individuals will have type 2 diabetes. It is estimated that one in seven adults have impaired glucose regulation and up to 12% of these will develop type 2 diabetes each year. The impact of obesity on the development of type 2 diabetes cannot be overemphasised, with a 1 kg/m2 increase in BMI raising the risk of impaired fasting glycaemia by 9.5% and of developing new-onset type 2 diabetes by 8.4%. A 1 cm increase in waist circumference increases the risks by 3.2% and 3.5% respectively. NICE advises using a validated risk assessment tool to identify patients at risk of diabetes. Risk factors used by such tools include: age; ethnicity; weight; first-degree relative with type 2 diabetes; low birthweight and sedentary lifestyle. Certain comorbidities increase the risk of type 2 diabetes, these include: cardiovascular and cerebrovascular disease; polycystic ovary syndrome; a history of gestational diabetes; and mental health problems. The initial screening blood test could be a fasting plasma glucose, HbA1c, or an oral glucose tolerance test, according to WHO criteria. NICE recommends that high-risk patients should be offered a programme encouraging them to undertake a minimum of 150 minutes of moderate intensity physical activity a week, gradually lose weight to reach and maintain a BMI within the healthy range, increase consumption of whole grains, vegetables, and other foods that are high in dietary fibre, reduce the total amount of fat in their diet and eat less saturated fat.

    Background Randomized trials have examined short-term effects of lifestyle interventions for diabetes prevention only among high-risk individuals. Prospective studies have examined the associations between lifestyle factors and diabetes in healthy populations but have not characterized the intervention. We estimated long-term effects of “hypothetical” lifestyle interventions on diabetes in a prospective study of healthy women, using the parametric g-formula. Methods Using data from the Nurses’ Health Study, we followed 76,402 women from 1984 to 2008. We estimated the risk of type 2 diabetes under 8 “hypothetical” interventions: quitting smoking, losing weight by 5% every 2 years if overweight/obese, exercising at least 30 minutes a day, eating less than 3 servings a week of red meat, eating at least 2 servings a day of whole grain, drinking 2 or more cups of coffee a day, drinking 5 or more grams of alcohol a day and drinking less than 1 serving of soda a week. Results The 24-year risk of diabetes was 9.6% under no intervention and 4.3% when all interventions were imposed (55% lower risk [95% confidence interval= 47% to 63%]). The most effective interventions were weight loss (24% lower risk), physical activity (19%) and moderate alcohol use (19%). Overweight/obese women would benefit the most, with 10.8 percentage points reduction in 24-year risk of diabetes. The validity of these estimates relies on absence of unmeasured confounding, measurement error, and model misspecification. Conclusion A combination of dietary and non-dietary lifestyle modifications, begun in mid-life or later in relatively healthy women, could have prevented at least half of the cases of type 2 diabetes in this cohort of US women.

  6. Safety impact--the risk/benefits of functional foods.

    PubMed

    Pascal, Gérard

    2009-12-01

    It is amazing to see how much the approach of the food risk analysis evolved in the recent years. For half a century and the birth of the risk assessment methodology in the food domain, only no appreciable health risk was considered acceptable by the manager. This is the vocabulary used in the case of a voluntary, deliberated human action, as the use of food additives (definition of ADI). In the case of risks not resulting from such an action, as that of the presence of contaminants, the risk assessor allocates provisional tolerable daily, weekly or monthly intake that are the basis for regulation. This vocabulary is in agreement with the objective which consists in approaching closer possible of the zero risk which is the wish of a majority of the consumers. Some years ago, the risk managers insisted to obtain from the assessors as often as possible a quantitative risk evaluation. More recently even, the managers would like to decide on the basis of a balance of risk and benefit acceptable for management purposes. Finally, they hope that general principles and tools will be available for conducting a quantitative risk-benefit analysis for foods and food ingredients. What is possible in the case of functional foods (FF)? Based on the definition of FF proposed in the programme FUFOSE, one has to distinguish between different situations in order to assess the risk: that of a micro-, that of a macro-component or that of a whole food. These situations have been clearly described in the document resulting from FOSIE. The standardized methodology relevant to assess micro-components is not well adapted to the assessment of whole food. Concepts of substantial equivalence and of history of safe use could be useful tools in this case. However, quantitative risk assessment remains a very difficult exercise. If a process for the assessment of health benefit of FF has been proposed as an outcome of the PASSCLAIM action, the quantification of this benefit needs adequate tools

    2016-01-01

    Diabetes mellitus is an independent risk factor for atherothrombotic cardiovascular disease. Adults with diabetes are two to four times more likely to develop heart disease or stroke than adults without diabetes. The two major features of diabetes, i.e., hyperglycemia and insulin-resistance, trigger arterial stiffening and increase the susceptibility of the arterial wall to atherosclerosis at any given age. These pathological changes in the arterial wall may provide a functional and structural background for cardiovascular events. The present paper provides a critical overview of the clinical evidence linking diabetes-related metabolic abnormalities to cardiovascular risk, debates the pathophysiologic mechanisms through which insulin resistance and hyperglycemia may affect the arterial wall, and discusses the associations between vascular biomarkers, metabolic abnormalities and cardiovascular events.

    Background Diabetic foot is a serious condition in patients with a long lasting diabetes mellitus. Diabetic foot treated improperly may lead not only to delayed ulceration healing, generalized inflammation, unnecessary surgical intervention, but also to the lower limb amputation. The aim of this study was to compare diabetic foot risk factors in population with type 2 diabetes and risk factors for diabetes in healthy subjects. Methods The study included 900 subjects: 145 with diabetic foot, 293 with type 2 diabetes without diabetic foot and 462 healthy controls matched in terms of mean age, gender structure and cardiovascular diseases absence. Study was conducted in Gastroenterology and Metabolic Diseases Department, Medical University of Warsaw, Poland. In statistical analysis a logistic regression model, U Mann-Whitney’s and t-Student test were used. Results The binomial logit models analysis showed that the risk of diabetic foot in patients with type 2 diabetes was decreased by patient’s age (odds ratio [OR] = 0.94; 95% confidence interval [CI]: 0.92-0.96; p = 0.00001) and hyperlipidaemia (OR = 0.54; 95% CI: 0.36-0.81; p = 0.01). In contrast, male gender (OR = 2.83; 95% CI: 1.86-4.28; p = 0.00001) diabetes duration (OR = 1.04; 95% CI: 1.03-1.06; p = 0.0003), weight (OR = 1.04; 95% CI: 1.03-1.06; p = 0.00001), height (OR = 1.08; 95% CI: 1.05-1.11; p = 0.00001) and waist circumference (OR = 1.028; 95% CI: 1.007-1.050; p = 0.006) increase the risk of diabetic foot. The onset of type 2 diabetes in healthy subjects was increased by weight (OR = 1.035; 95% CI: 1.024-1.046; p = 0.00001), WC (OR = 1.075; 95% CI: 1.055-1.096; p = 00001), hip circumference (OR = 1.03; 95% CI: 1.01-1.05; p = 0.005), overweight defined with body mass index (BMI) above 24,9 kg/m2 (OR = 2.49; 95% CI: 1.77-3.51; p = 0.00001) and hyperlipidaemia (OR = 3.53; 95% CI: 2.57-4.84; p = 0.00001).

    Diabetic foot ulcers are the main cause of non-traumatic lower extremity amputation. The objective of this study was to evaluate the risk factors for major amputation in diabetic foot patients. Eight hundred and sixty diabetic patients were admitted to the diabetic wound centre of the Korea University Guro Hospital for foot ulcers between January 2010 and December 2013. Among them, 837 patients were successfully monitored until complete healing. Ulcers in 809 patients (96·7%) healed without major amputation and those in 28 patients (3·3%) healed with major amputation. Data of 88 potential risk factors including demographics, ulcer condition, vascularity, bioburden, neurology and serology were collected from patients in the two groups and compared. Among the 88 potential risk factors, statistically significant differences between the two groups were observed in 26 risk factors. In the univariate analysis, which was carried out for these 26 risk factors, statistically significant differences were observed in 22 risk factors. In a stepwise multiple logistic analysis, six of the 22 risk factors remained statistically significant. Multivariate-adjusted odds ratios were 11·673 for ulcers penetrating into the bone, 8·683 for dialysis, 6·740 for gastrointestinal (GI) disorders, 6·158 for hind foot ulcers, 0·641 for haemoglobin levels and 1·007 for fasting blood sugar levels. The risk factors for major amputation in diabetic foot patients were bony invasions, dialysis, GI disorders, hind foot locations, low levels of haemoglobin and elevated fasting blood sugar levels.

    Objectives: To assess the proportion and grades of retinopathy and its risk factors in diabetes type 2 patients. Materials and Methods: This was a cross-sectional study of 401 type 2 diabetic patients. A questionnaire and checklist were used to collect the data. Retinopathy was diagnosed and graded by fundus photographs and slit lamp examination. The duration of diabetes, age of patients, age at onset of diabetes, body mass index, hemoglobin A1c level, blood pressure, and complications were noted. Results: The mean age of male and female patients was 54.93 and 54.25 years; 57.6% were males. The mean age of onset and mean duration of diabetes were 43.91 and 13.4 years, respectively. The proportion of retinopathy was 36.4%. Grades of retinopathy were: Mild 57.5%, moderate 19.9%, severe nonproliferative 11%, and proliferative retinopathy 11.6%; 7.2% of patients had maculopathy. Retinopathy was significantly associated with older age, younger age at onset, longer duration of disease, poorly controlled blood sugar, hypertension, insulin use; the presence of neuropathy and nephropathy appeared as a significant risk. Younger age at onset, longer duration, and insulin use appeared as the strongest predictors for diabetic retinopathy. Conclusions: More than a third (36.4%) of the diabetic patients attending a diabetic center had retinopathy. The control of the risk factors may reduce both prevalence and consequences of retinopathy. PMID:26929725

    Women with pre-existing abnormal glucose regulation are certain to develop gestational diabetes in pregnancy and pre-gestational type 2 diabetes will become more difficult to control. However, an increasing number of women with type 2 diabetes have had bariatric surgery. In this group, the effect of pregnancy on glucose metabolism is unknown. We report two women with type 2 diabetes who underwent laparoscopic gastric bypass surgery with normalization of plasma glucose levels. During subsequent pregnancy, maternal blood glucose levels remained completely normal throughout. This is remarkable given the predisposition to abnormal glucose tolerance and the ongoing obesity, in the face of the insulin resistance of pregnancy. Women with prior type 2 diabetes reversed by gastric bypass surgery are not at high risk for gestational diabetes.

    Falls are a major health issue for older adults, especially for those who develop type 2 diabetes who must contend with age-related declines in balance, muscle strength, and walking ability. They must also contend with health-related issues specific to the disease process. Given the general association between these variables and falls, being able to identify which measures negatively impact on balance in older diabetic persons is a critical step. Moreover, designing specific interventions to target these physiologic functions underlying balance and gait control will produce the greatest benefit for reducing falls in older persons with diabetes.

    Land subsidence, a major and well-known geological hazard in Shanghai, has caused serious losses. Based on past studies, the cost and benefit of the Shanghai's land subsidence hazard control were assessed and forecasted by risk assessment. An economic benefit-risk assessment was taken in order to control completely land subsidence and make rational safety elevations of the flood control wall. The result of risk assessment shows that the present 6.9-m elevation of the floodwall is not sufficient for the standard of “occurring only once in a thousand years.∝ After 200 years, the spring tide hazardous risk losses caused by land subsidence would amount to 49.73 million yuan per year. The proportion of expense in thoroughly controlling land subsidence to the economic benefit is 1∶:41.44; to construct the flood control wall to an elevation that would prevent inundation from a flood event, to reach the standard of “occurring only once in a thousand years,∝ and to avoid tide losses, the ratio of the investment of reducing tide hazard to the economic benefit should be 1∶:53.24.

    2013-11-01

    Prevention of high incidence of cardiovascular disease in diabetes is one of the challenges of endocrinology. Validation of new biomarkers that may contribute to a better assessment of cardiovascular risk and help implement treatment strategies is one of the promising approaches in research on prevention and reduction of cardiovascular risk. Modification of low density lipoprotein (LDL) is a key element in development of atherosclerotic lesions. Several pathophysiological characteristics of diabetes are crucial for the LDL of these patients to have higher modification rates as compared to the healthy population. Diabetic dyslipidemia, hyperglycemia, and oxidative stress synergistically promote the occurrence of lipoperoxidation, glycosylation and glycoxidation processes, which will generate modified lipoproteins that stimulate development of atherosclerosis. This article reviews the role of different types of modified LDL in development of atherosclerosis in diabetes, as well as the possibility of using its quantification in cardiovascular risk prediction.

    2008-11-01

    Convincing African American and other young adults that obesity increases their risk for diabetes and its complications is challenging for health educators and clinicians. At a historically Black university (HBCU) this question was examined, Do overweight and obese African American freshmen have higher risks for diabetes through low physical activity or toning and poor nutritional habits? Survey data found 40% of the 101 respondents sampled there were obese (defined as body mass index of 30 or more kg/m2), which is a higher proportion of obesity than found in other college health surveys. Scores reflecting higher risks of diabetes mellitus were significantly related to higher BMI values and low aerobic physical activity. Students had low levels of physical activity and toning than reported in general college populations. To reduce diabetes-disparity risks and obesity-related behaviors, African American younger adult freshmen may benefit from effective intervention strategies targeting them. PMID:19029739

    Background The increase in prevalence of diabetes and pre-diabetes in sub-Saharan Africa underlines the importance of understanding its magnitude and causes in different population groups. We analyzed data from the Africa/Harvard Partnership for Cohort Research and Training (PaCT) studies to determine the prevalence of diabetes and pre-diabetes and risk factors associated with diabetes. Methodology Participants were randomly selected from peri-urban (n=297) and rural (n=200) communities in Uganda, and teachers were recruited from schools (n=229) in urban Tanzania. We used a standardized questionnaire to collect socio-demographic and self-reported disease status including diabetes status. Blood glucose was also measured after participants fasted for 8 h. We used standard protocols for anthropometric and blood pressure measurement. Results The overall prevalence of diabetes was 10.1% and was highest in rural Ugandan residents (16.1%) compared to teachers in Tanzania (8.3%) and peri-urban Ugandan residents (7.6%). The prevalence of pre-diabetes was 13.8%. The prevalence of self-reported diabetes was low across all sites, where 68% of participants with diabetes were not captured by self-report. In multivariable logistic regression analysis, family history (OR 2.5, 95% CI: 1.1, 5.6) and hypertension (OR 2.3, 95% CI: 1.1, 5.2) were significantly associated with diabetes. Conclusions The prevalence of diabetes and pre-diabetes in Uganda and Tanzania is high, differs markedly between population groups, and remains undiagnosed in an alarmingly high proportion of individuals. These findings highlight the need for large-scale, prospective studies to accurately quantify the burden and identify effective intervention and treatment strategies across diverse African populations.

  2. The role of risk and cost benefit in program budgeting

    The primary Environmental Management (EM) program mission is protecting human health and the environment. EM is currently facing a decreasing budget while still having to deal with competing requirements and risks to workers, public, and environment. There has been no consistent framework for considering in an integrated fashion the multiple types of risks and hazards present in the nuclear weapons complex. Therefore, to allocate resources during the budget process, EM is using risk, long term costs, mortgage reduction, compliance issues, and stakeholders concerns to prioritize the funding of activities. Risk and cost-benefit analysis are valuable tools to help make decisions to reduce risks to health, safety, and the environment in a sensible and cost-effective manner. Principles for priority setting using risk analysis are to seek to compare risks by grouping them into broad categories of concern (e.g., high, medium, and low); to set priorities in managing risks to account for relevant management and social considerations; to inform priorities by as broad a range of views as possible, ideally with consensus; and, to try to coordinate risk reduction efforts among programs. The Draft Risk Report to Congress, Risks and the Risk Debate: Searching for Common Ground {open_quote}The First Step,{close_quote} provides the first link between budget, compliance requirements, and risk reduction/pollution prevention activities. The process used for the report provides an initial framework to capture the spectrum of risks associated with environmental management activities and to link these risks in a qualitative fashion to compliance and the budget.

  3. Risk assessment for invasive species produces net bioeconomic benefits

    2007-01-01

    International commerce in live organisms presents a policy challenge for trade globalization; sales of live organisms create wealth, but some nonindigenous species cause harm. To reduce damage, some countries have implemented species screening to limit the introduction of damaging species. Adoption of new risk assessment (RA) technologies has been slowed, however, by concerns that RA accuracy remains insufficient to produce positive net economic benefits. This concern arises because only a small proportion of all introduced species escape, spread, and cause harm (i.e., become invasive), so a RA will exclude many noninvasive species (which provide a net economic benefit) for every invasive species correctly identified. Here, we develop a simple cost:benefit bioeconomic framework to quantify the net benefits from applying species prescreening. Because invasive species are rarely eradicated, and their damages must therefore be borne for long periods, we have projected the value of RA over a suitable range of policy time horizons (10–500 years). We apply the model to the Australian plant quarantine program and show that this RA program produces positive net economic benefits over the range of reasonable assumptions. Because we use low estimates of the financial damage caused by invasive species and high estimates of the value of species in the ornamental trade, our results underestimate the net benefit of the Australian plant quarantine program. In addition, because plants have relatively low rates of invasion, applying screening protocols to animals would likely demonstrate even greater benefits. PMID:17190819

    Widespread proposals to benefit form lessons of the 17 October 1989 (Loma Prieta) earthquake dramatize the difficulties associated with reducing seismic risk. There are three main problems. First, the understanding of earthquake generation is far form complete. For example, the unanticipated source style of this earthquake raises vital questions; claims of predicting its occurrence are weak, and, for practical reasons, the detailed pattern of damaging strong ground shaking was not predicted. Second, although their interactions are not well understood, competing social forces continue to prevent the optimum growth and application of knowledge for earthquake hazard mitigation. Third, the recent use of the probabilities of seismic risk has had mixed results. Because of indecision between minimizing loss of life and maximizing broader benefits, general agreement on acceptable earthquake risk remains confused.

    The incidence of type 1 diabetes has risen considerably in the past 30 years due to changes in the environment that have been only partially identified. In this Series paper, we critically discuss candidate triggers of islet autoimmunity and factors thought to promote progression from autoimmunity to overt type 1 diabetes. We revisit previously proposed hypotheses to explain the growth in the incidence of type 1 diabetes in light of current data. Finally, we suggest a unified model in which immune tolerance to β cells can be broken by several environmental exposures that induce generation of hybrid peptides acting as neoautoantigens.

  6. Biotechnology risks and benefits: Science instructor perspectives and practices

    Developing scientifically literate students who understand the socially contextualized nature of science and technology is a national focus of science education reform. Understanding teachers' views on this topic is of equal importance. This document focuses on the topic of risks and benefits posed by science and technology as an important topic for which the socially contextualized nature of science and technology readily emerges. Following introduction of a theoretical model and a review of the literature, two research studies are described that examined teachers' perceptions of the risks posed by biotechnology and the role of risk topics in an undergraduate science course. The first research study examines four groups of science educators; pre-service science teachers, in-service science teachers, science graduate teaching assistants, and science professors (n = 91). The participants completed a survey and card sort task to determine their perceptions of the risks of biotechnology. The results show that teacher perceptions were shaped by the risk severity, regulation processes, public acceptance, fear, reciprocal benefits, and whether the applications would impact humans or the environment. Factors determining risk perception included personal worldviews, trust in communicating institutions, and personal experiences with biotechnology. The different types of science teachers were compared and contrasted in light of these factors and the implications of instructor perceptions on science pedagogy are discussed. The second research manuscript describes a case study in which six biology graduate teaching assistants (GTAs) were observed teaching as lesson on the potential risks and benefits of biotechnology. The data sources included classroom observations and semi-structured interviews. Qualitative analysis reveals that GTAs framed the instruction of risk in one of three ways: analytical, focus on perspectives and biases, and promotion of individual reflection

    All racial/ethnic groups are at higher risk for type 2 diabetes compared to whites, but it is unknown if young adults recognize their risk. Risk knowledge and individual risk perception were examined in 1579 multiracial urban college students. Students have little knowledge of diabetes risk factors; identifying less than three of ten. Considerable variation exists in the understanding of risk; only .02 % of Asian, 14.0 % of Hispanic and 22.8 % of black students recognized that their race increased risk. Among those with ≥3 risk factors (n = 541) only 39 % perceived their risk. These under-estimators had lower knowledge scores (p = .03) than those who acknowledged their risk; indicating that the cause of under-estimating risk may be, at least, in part due to a lack of information. There is a pressing need to heighten understanding of type 2 diabetes risk among young adults to decrease the future burden of this disease. PMID:26169506

    Neighborhood characteristics have been associated with both depression and diabetes, but to date little attention has been paid to whether the association between depression and diabetes varies across different types of neighborhoods. This prospective study examined the relationship between depression, neighborhood deprivation, and risk of type 2 diabetes among 336,340 adults from a national-representative sample of primary care centers in Sweden (2001–2007). Multi-level logistic regression models were used to assess associations between depression and risk of type 2 diabetes across affluent and deprived neighborhoods. After accounting for demographic, individual-level socioeconomic, and health characteristics, depression was significantly associated with risk of diabetes (odds ratio (OR): 1.10, 95% confidence interval (CI): 1.06–1.14), as was neighborhood deprivation (OR for high vs. low deprivation: 1.66, 95% CI: 1.22–1.34). The interaction term between depression and neighborhood deprivation was non-significant, indicating that the relationship between depression and diabetes risk is similar across levels of neighborhood socioeconomic deprivation.

    Background: Beneficial effects of fish consumption on early cognitive development and cardiovascular health have been attributed to the omega-3 fatty acids in fish and fish oils, but toxic chemicals in fish may adversely affect these health outcomes. Risk–benefit assessments of fish consumption have frequently focused on methylmercury and omega-3 fatty acids, not persistent pollutants such as polychlorinated biphenyls, and none have evaluated Great Lakes fish consumption. Objectives: The risks and benefits of fish consumption have been established primarily for marine fish. Here, we examine whether sufficient data are available to evaluate the risks and benefits of eating freshwater fish from the Great Lakes. Methods: We used a scoping review to integrate information from multiple state, provincial, and federal agency sources regarding the contaminants and omega-3 fatty acids in Great Lakes fish and fish consumers, consumption rates and fish consumption advisories, and health effects of contaminants and omega-3 fatty acids. Data synthesis: Great Lakes fish contain persistent contaminants—many of which have documented adverse health effects —that accumulate in humans consuming them. In contrast, data are sparse on omega-3 fatty acids in the fish and their consumers. Moreover, few studies have documented the social and cultural benefits of Great Lakes fish consumption, particularly for subsistence fishers and native communities. At this time, federal and state/provincial governments provide fish consumption advisories based solely on risk. Conclusions: Our knowledge of Great Lakes fish has critical gaps, particularly regarding the benefits of consumption. A risk–benefit analysis requires more information than is currently available on the concentration of omega-3 fatty acids in Great Lakes fish and their absorption by fish eaters in addition to more information on the social, cultural, and health consequences of changes in the amount of fish consumed.

    This paper presents preliminary results of a study to evaluate the risk-reduction benefits of wind power for a case study utility system using decision analysis techniques. The costs and risks of two alternative decisions-whether to build a 400 MW gas-fired combined cycle plant or a 1600 MW wind plant in 2003-were compared through computer simulations as fuel prices, environmental regulatory costs, wind and conventional power plant availability, and load growth were allowed to vary. Three different market scenarios were examined: traditional regulation, a short-term power pool, and fixed-price contracts of varying duration. The study concludes that, from the perspective of ratepayers, wind energy provides a net levelized risk-reduction benefit of $3.4 to $7.8/MWh under traditional regulation, and less in the other scenarios. From the perspective of the utility plant owners, wind provides a significant risk benefit in the unregulated market scenarios but none in a regulated market. The methodology and findings should help inform utility resource planning and industry restructuring efforts. 2 figs., 3 tabs.

    Objective: The objective of the current study was to maximise the amount of information children and adolescents understand about the risks and benefits associated with participation in a biomedical research study. Design: Participants were presented with one of six hypothetical research protocols describing how to fix a fractured thigh using either a "standard" cast or "new" pins procedure. Risks and benefits associated with each of the treatment options were manipulated so that for each one of the six protocols there was either a correct or ambiguous choice. Participants and setting: Two hundred and fifty one children, ages 6–15 (53% boys), and 237 adults (30% men) were interviewed while waiting for a clinic appointment at the Hospital for Sick Children. Results: Using standardised procedures and questionnaires, it was determined that most participants, regardless of age group, were able to understand the basic purpose and procedures involved in the research, and most were able to choose the "correct" operation. The younger children, however, showed an overall preference for a cast operation, whereas the older participants were more likely to choose the pins. Conclusions: By creating age appropriate modules of information, children as young as six years can understand potentially difficult and complex concepts such as the risks and benefits associated with participation in biomedical research. It appears, however, that different criteria were used for treatment preference, regardless of associated risks; older participants tended to opt for mobility (the pins procedure) whereas younger participants stayed with the more familiar cast operation.

  13. Survival Association Rule Mining Towards Type 2 Diabetes Risk Assessment

    2013-01-01

    Type-2 Diabetes Mellitus is a growing epidemic that often leads to severe complications. Effective preventive measures exist and identifying patients at high risk of diabetes is a major health-care need. The use of association rule mining (ARM) is advantageous, as it was specifically developed to identify associations between risk factors in an interpretable form. Unfortunately, traditional ARM is not directly applicable to survival outcomes and it lacks the ability to compensate for confounders and to incorporate dosage effects. In this work, we propose Survival Association Rule (SAR) Mining, which addresses these shortcomings. We demonstrate on a real diabetes data set that SARs are naturally more interpretable than the traditional association rules, and predictive models built on top of these rules are very competitive relative to state of the art survival models and substantially outperform the most widely used diabetes index, the Framingham score.

    Subclinical hypothyroidism (SCH) is defined as elevated thyroid stimulating hormone (TSH) with normal levels of free triiodothyronine (FT3) and free thyroxine (FT4). SCH is further classified into a milder condition with TSH levels between 4.0 and 10.0 milli-international units (mIU)/l (mild-SCH) and a severe form with TSH >10.0 mIU/l (severe-SCH). SCH is a common problem (prevalence is greater in women than men), which increases further with increasing age and TSH levels. Even though the risk of progression to overt hypothyroidism is higher in patients with severe-SCH, the risk is also significant in patients having mild-SCH; it has been suggested that every twofold rise in serum TSH would increase the risk from 1 to 4%, which further increases to 38% if thyroid antibodies are positive. Current data have shown increased cardiovascular risk in patients with mild-SCH and have demonstrated some benefits of levothyroxine treatment in reducing these events. However, evidence on the association of mild-SCH and musculoskeletal system, cognitive dysfunction, mood disorders, dyslipidaemia, diabetes and goitre is conflicting. Similarly, the discussion regarding the exact upper limit of normal for serum TSH remains controversial. The data have also shown increased risk of adverse pregnancy outcomes in patient with mild-SCH, with some benefits of thyroxine treatment. The recent available guidelines related to management of patients with serum TSH <10 mIU/l have suggested decisions should be made taking into account the age of the patient, associated risk factors and comorbid conditions. This chronicle review assesses current evidence regarding the risks associated and the recommendations related to benefits of levothyroxine treatment in patients having mild-SCH. PMID:26885359

    2016-05-01

    Hemoglobin A1c (HbA1c) is a widely used tool for diagnosing, screening, and managing patients with diabetes; however, proper application and interpretation of the HbA1c test is crucial to master for accurate assessment of patients. It also has become the standard test in population-based studies for evaluating the relationship between glycemic control and cardiovascular risk. Results from large clinical trials support the modern perspective that the HbA1c target should be personalized according to the risks and benefits of glycemic control. This likely is most important in patients with diabetes and elevated cardiovascular risk in whom achieving low HbA1c levels early in the natural history may be the most beneficial. PMID:27176682

    How is public opinion towards nanotechnology likely to evolve? The `familiarity hypothesis' holds that support for nanotechnology will likely grow as awareness of it expands. The basis of this conjecture is opinion polling, which finds that few members of the public claim to know much about nanotechnology, but that those who say they do are substantially more likely to believe its benefits outweigh its risks. Some researchers, however, have avoided endorsing the familiarity hypothesis, stressing that cognitive heuristics and biases could create anxiety as the public learns more about this novel science. We conducted an experimental study aimed at determining how members of the public would react to balanced information about nanotechnology risks and benefits. Finding no support for the familiarity hypothesis, the study instead yielded strong evidence that public attitudes are likely to be shaped by psychological dynamics associated with cultural cognition.

  19. Assisted Death: The Risks and Benefits of Tribunal Approval.

    PubMed

    Handelman, Mark

    2016-02-01

    Should every request for physician-assisted death require approval from some kind of independent tribunal? The benefits include consistent interpretation of statutory or judge-created guidelines from hospital to hospital, accurate reporting of assisted deaths, a process that protects vulnerable patients and health practitioners, and assurance to the public that the process has sufficient safeguards. On the other hand, such a process might cause delays for persons suffering intolerably. Accessibility might be a problem, and there is the risk that the patient's personal health information becomes fodder for media sensationalism. The author weighs these risks and benefits and concludes that a tribunal approval process is a transparent system capable of helping the law clearly gel in a way that provides guidelines, encourages trust in the healthcare process generally and the assisted death process specifically.

    Evidence supports the use of opioids for treating acute pain. However, the evidence is limited for the use of chronic opioid therapy for chronic pain. Furthermore, the risks of chronic therapy are significant and may outweigh any potential benefits. When considering chronic opioid therapy, physicians should weigh the risks against any possible benefits throughout the therapy, including assessing for the risks of opioid misuse, opioid use disorder, and overdose. When initiating opioid therapy, physicians should consider buprenorphine for patients at risk of opioid misuse, opioid use disorder, and overdose. If and when opioid misuse is detected, opioids do not necessarily need to be discontinued, but misuse should be noted on the problem list and interventions should be performed to change the patient's behavior. If aberrant behavior continues, opioid use disorder should be diagnosed and treated accordingly. When patients are discontinuing opioid therapy, the dosage should be decreased slowly, especially in those who have intolerable withdrawal. It is not unreasonable for discontinuation of chronic opioid therapy to take many months. Benzodiazepines should not be coprescribed during chronic opioid therapy or when tapering, because some patients may develop cross-dependence. For patients at risk of overdose, naloxone should be offered to the patient and to others who may be in a position to witness and reverse opioid overdose. PMID:27304767

    Background: Moderate alcohol consumption is associated with a decreased risk of type 2 diabetes in the general population, but little is known about the effects in individuals at high risk of diabetes. Objectives: The objectives were to determine associations between alcohol consumption and diabetes risk factors and whether alcohol consumption was a predictor of incident diabetes in individuals enrolled in the Diabetes Prevention Program (DPP). Design: DPP participants (n = 3175) had impaired glucose tolerance (2-h glucose: 7.8–11.1 mmol/L), elevated fasting glucose (5.3–7.0 mmol/L), and a body mass index (in kg/m2) ≥24. Participants were randomly assigned to placebo, metformin, or lifestyle modification and were followed for a mean of 3.2 y. Alcohol intake was assessed at baseline and year 1 by using a semiquantitative food-frequency questionnaire. Diabetes was diagnosed by annual oral-glucose-tolerance testing and semiannual fasting plasma glucose measurement. Results: Participants who reported higher alcohol consumption tended to be male, older, white, and less obese and to have a higher calorie intake and a higher HDL-cholesterol concentration. Higher alcohol consumption was associated with lower insulin secretion at any level of insulin sensitivity. We found lower incidence rates of diabetes with higher alcohol consumption in the metformin (P < 0.01 for trend) and lifestyle modification (P = 0.02 for trend) groups, which remained significant after adjustment for multiple baseline covariates. No similar association was observed in the placebo group. Conclusions: Despite overall low rates of alcohol consumption, there was a reduced risk of incident diabetes in those who reported modest daily alcohol intake and were assigned to metformin or lifestyle modification. Moderate daily alcohol intake is associated with lower insulin secretion—an effect that warrants further investigation. This trial was registered at clinicaltrials.gov as NCT00038727. PMID

    Objective To evaluate current risk models and scores for type 2 diabetes and inform selection and implementation of these in practice. Design Systematic review using standard (quantitative) and realist (mainly qualitative) methodology. Inclusion criteria Papers in any language describing the development or external validation, or both, of models and scores to predict the risk of an adult developing type 2 diabetes. Data sources Medline, PreMedline, Embase, and Cochrane databases were searched. Included studies were citation tracked in Google Scholar to identify follow-on studies of usability or impact. Data extraction Data were extracted on statistical properties of models, details of internal or external validation, and use of risk scores beyond the studies that developed them. Quantitative data were tabulated to compare model components and statistical properties. Qualitative data were analysed thematically to identify mechanisms by which use of the risk model or score might improve patient outcomes. Results 8864 titles were scanned, 115 full text papers considered, and 43 papers included in the final sample. These described the prospective development or validation, or both, of 145 risk prediction models and scores, 94 of which were studied in detail here. They had been tested on 6.88 million participants followed for up to 28 years. Heterogeneity of primary studies precluded meta-analysis. Some but not all risk models or scores had robust statistical properties (for example, good discrimination and calibration) and had been externally validated on a different population. Genetic markers added nothing to models over clinical and sociodemographic factors. Most authors described their score as “simple” or “easily implemented,” although few were specific about the intended users and under what circumstances. Ten mechanisms were identified by which measuring diabetes risk might improve outcomes. Follow-on studies that applied a risk score as part of an

    This paper describes the recent work of the authors on the evaluation of health risk benefits of space disposal of nuclear waste. The paper describes a risk model approach that has been developed to estimate the non-recoverable, cumulative, expected radionuclide release to the earth's biosphere for different options of nuclear waste disposal in space. Risk estimates for the disposal of nuclear waste in a mined geologic repository and the short- and long-term risk estimates for space disposal were developed. The results showed that the preliminary estimates of space disposal risks are low, even with the estimated uncertainty bounds. If calculated release risks for mined geologic repositories remain as low as given by the U.S. DOE, and U.S. EPA requirements continue to be met, then no additional space disposal study effort in the U.S. is warranted at this time. If risks perceived by the public are significant in the acceptance of mined geologic repositories, then consideration of space disposal as a complement to the mined geologic repository is warranted.

    2011-01-01

    Trials have demonstrated the preventability of type 2 diabetes through lifestyle modifications or drugs in people with impaired glucose tolerance. However, alternative ways of identifying people at risk of developing diabetes are required. Multivariate risk scores have been developed for this purpose. This article examines the evidence for performance of diabetes risk scores in adults by 1) systematically reviewing the literature on available scores and 2) their validation in external populations; and 3) exploring methodological issues surrounding the development, validation, and comparison of risk scores. Risk scores show overall good discriminatory ability in populations for whom they were developed. However, discriminatory performance is more heterogeneous and generally weaker in external populations, which suggests that risk scores may need to be validated within the population in which they are intended to be used. Whether risk scores enable accurate estimation of absolute risk remains unknown; thus, care is needed when using scores to communicate absolute diabetes risk to individuals. Several risk scores predict diabetes risk based on routine noninvasive measures or on data from questionnaires. Biochemical measures, in particular fasting plasma glucose, can improve prediction of such models. On the other hand, usefulness of genetic profiling currently appears limited. PMID:21622851

  7. Risks and benefits of PVC in medical applications.

    2002-01-01

    The safety of using PVC in the medical field has been recently challenged due to the toxic activity it allegedly exerts on exposed patients. The environmental repercussions of disposing of PVC, once its use has terminated, represent an additional point of debate, used to sustain the advisability of abolishing PVC. The reasons that have led some to request the abolition of PVC involve valid questions of principle, perhaps, but they lack a technical evaluation of the benefit-risk ratio and the possible consequences this action would have on patients and on healthcare personnel. The purpose of this paper is therefore to help bring the terms of the question back into the realm of evidence and proof, attempting to formulate a brief picture of what is known, in terms of PVC uses in the clinical field, evaluating the benefits and risks to human health and to the environment, also in relation to possible alternatives, and discussing the margins of uncertainty that emerge. Evidence supports the conclusion that PVC is an important weapon in the complex arsenal medicine has at its disposal to care for patients and cure diseases. Though its use can be considered safe, recent surveys have identified in some patients possibility of risks associated with DEHP, the principal plasticizer of PVC for medical applications. Studies are in progress to eliminate these margins of risk and increase the safety for patients. PMID:12426816

    Women with a history of gestational diabetes mellitus (GDM) have a high chance of developing type 2 diabetes mellitus (T2DM) following the index pregnancy, however, little is known of women's perception of this risk. The objectives were to (1) determine women's perception of risk of future development of T2DM following a GDM pregnancy and (2) describe the prevalence of undetected dysglycaemia in a Canadian population. The study was designed as a 9–11 year follow-up study of women previously enrolled in a randomized controlled trial of tight versus minimal intervention for GDM. Women's perception of future risk of diabetes was determined by questionnaire. Fasting lipid profile, height and weight were performed on all participants. Oral glucose tolerance tests were performed on all women without prior history of diabetes mellitus type 2 (DM2). The study was conducted at Ottawa Hospital General Campus and Children's Hospital of Eastern Ontario, in Ottawa, Canada. Eighty-nine of 299 (30%) of the original cohort were recruited. Eighty-eight women completed the questionnaire and 77 women without known diabetes underwent two hour glucose tolerance testing. Twenty-three (30%) felt their risk was no different than other women or did not know, 27 (35%) felt risk was increased a little and 27 (35%) felt risk was increased a lot. Only 52% (40/77) had normal glucose tolerance. Of all, 25/88 (28%) patients had diabetes (11 previously diagnosed and 14 diagnosed within the study). Of those newly diagnosed with DM2, four (29%) were diagnosed by fasting glucose, six (42%) by two hour glucose tolerance test (GTT) alone and four (29%) by both. Twenty-four of the women (27%) had impaired glucose tolerance (IGT). Of those with IGT, 12 (57%) had a fasting food glucose < 5.6 mmol/L. In the high-risk perception group with newly diagnosed diabetes, two were overweight, seven were obese, four had a family history of DM2, and all had a waist circumference >88 cm. In conclusion the

A total of 213 participants selected from a ten-year longitudinal Shanghai Diabetes Study (SHDS) were examined in two ways: 1) 51 subjects who developed diabetes and 162 individuals who remained metabolically healthy in 10 years; 2) the same 51 future diabetes and 23 strictly matched ones selected from the 162 healthy individuals. Baseline fasting serum tryptophan concentrations were quantitatively measured using ultra-performance liquid chromatography triple quadruple mass spectrometry. First, serum tryptophan level was found significantly higher in future T2D and was positively and independently associated with diabetes onset risk. Patients with higher tryptophan level tended to present higher degree of insulin resistance and secretion, triglyceride and blood pressure. Second, the prediction potential of tryptophan is non-inferior to the 5 existing amino acids. The predictive performance of the combined score improved after taking tryptophan into account. Our findings unveiled the potential of tryptophan as a new marker associated with diabetes risk in Chinese populations. The addition of tryptophan provided complementary value to the existing amino acid predictors. PMID:27598004

    An association between type 2 diabetes mellitus (DM) and cancer has long been postulated, but the biological mechanism responsible for this association has not been defined. In part one of this review, we discussed the epidemiological evidence for increased risk of cancer, decreased cancer survival, and decreased rates of cancer screening in diabetic patients. Here we review the risk factors shared by cancer and DM and how DM medications play a role in altering cancer risk. Hyperinsulinemia stands out as a major factor contributing to the association between DM and cancer, and modulation of circulating insulin levels by DM medications appears to play an important role in altering cancer risk. Drugs that increase circulating insulin, including exogenous insulin, insulin analogs, and insulin secretagogues, are generally associated with an increased cancer risk. In contrast, drugs that regulate insulin signaling without increasing levels, especially metformin, appear to be associated with a decreased cancer risk. In addition to hyperinsulinemia, the effect of DM medications on other shared risk factors including hyperglycemia, obesity, and oxidative stress as well as demographic factors that may influence the use of certain DM drugs in different populations are described. Further elucidation of the mechanisms behind the association between DM, cancer, and the role of DM medications in modulating cancer risk may aid in the development of better prevention and treatment options for both DM and cancer. Additionally, incorporation of DM medication use into cancer prediction models may lead to the development of improved risk assessment tools for diabetic patients. PMID:22527174

  11. Combined hormonal contraceptives: prescribing patterns, compliance, and benefits versus risks

    PubMed Central

    2014-01-01

    Combined hormonal contraceptives [combined oral contraceptives (COCs)] have been available for over 50 years and the impact of this invention may not be overestimated. Today over 100 million women are current users and in Western Europe and the United States approximately 80% of women of fertile ages can be considered as ever-users. Over the years several drawbacks have been identified and media alarms on risks are frequently presented, resulting in suboptimal compliance and low compliance and continuation rates. Poor compliance and discontinuation is a big problem and is not generally identified by prescribers. During ideal use COCs offer very good protection against unwanted pregnancies, however there is a big problem with compliance and continuation and thus the ‘real-life’ efficacy is much lower. Reasons for poor compliance include side effects and fear of side effects and it is crucial that the prescriber gives the individual woman thorough and balanced information on the benefits and risks. Most well known is the increased risk of venous thromboembolism, but also an elevated risk of arterial thrombosis and several types of cancer has been reported. The risk estimates are low but according to the large number of users a substantial number of extra cases will occur. However, use of COCs also offers several additional health benefits with significant impact on morbidity and quality of life. COC use is associated with a substantial decrease in the risk of ovarian cancer, endometrial cancer and colorectal cancer. Moreover, COCs are a major option of treatment for women suffering from heavy menstrual bleeding and dysmenorrhea as well as hirsutism and acne vulgaris. The net effect of the additional health effects of COC- use may very well be positive, i.e. a slight increase in life expectancy. PMID:25360241

  12. Preventing amputation in adults with diabetes: identifying the risks.

    Good management of diabetes can reduce the risk of complications of the disease. When not well managed, diabetes is associated with the complications of heart disease, stroke, blindness, kidney disease and amputations. Diabetes can reduce the blood supply to the feet and cause a loss of feeling. As a result, foot injuries do not heal well and the person may not realise that their foot is sore or injured. Damage to the foot may lead to the development of foot ulcers, which if left untreated may result in amputation of the limb. Preventive care is a priority, but when complications occur the next step is to halt progression. Therefore, effective foot care and timely treatment of foot ulcers are important in preserving foot function and mobility, and preventing amputation in adults with diabetes. PMID:26036406

    Objective Diabetes prevalence among ethnic minorities and immigrants often differs from the majority indigenous population. We compared diabetes prevalence, incidence and risk among Ethiopian and non-Ethiopian Jews. Within these main groups, we controlled for the effect of migration on diabetes risk by comparing the subgroups of Ethiopian and former Soviet Union (FSU) immigrants, and compared both with Israeli-born non-Ethiopian Jews. Methods The study cohort included adult Ethiopian (n = 8,398) and age-matched non-Ethiopian Jews (n = 15,977) and subgroups: Ethiopian immigrants (n = 7,994), FSU immigrants (n = 1,541) and Israeli-born non-Ethiopian Jews (n = 10,828). Diabetes prevalence, annual incidence, and hazard ratios (HRs) adjusted for sex and metabolic syndrome (MetS)-components, were determined in three age groups (<50yrs, 50-59yrs, and ≥60yrs). Comparisons of body mass index (BMI) at diabetes incidence were made. Results Younger (<50yrs) Ethiopians had higher prevalence rates, 3.6% (95%CI: 3.1–4.1) and annual incidence, 0.9% (95%CI: 0.8–1.0) than non-Ethiopians, 2.7% (95%CI: 2.3–3.0) and 0.5% (95%CI: 0.4–0.6), respectively. These differences were particularly pronounced among Ethiopian women. Diabetes risk among Ethiopians was higher and adjustment for MetS-components was important only for BMI, which further increased hazard ratio (HR) estimates associated with Ethiopian ethnicity from 1.81 (95% CI:1.50–2.17) to 2.31 (95% CI:1.91–2.79). The same differences were seen when comparing Ethiopian to FSU immigrants. BMI before incident diabetes was lower among younger Ethiopian immigrants than younger FSU immigrants and Israeli-born. Conclusions Ethiopian ethnicity is associated with increased diabetes risk, which is age and BMI dependent. Young Ethiopians<50yrs, particularly women, had the greatest increase in risk. Lower BMI cut-offs should be defined to reflect diabetes risk among Ethiopians. PMID:27300299

    2010-01-01

    Computed tomography (CT) is a powerful tool for the accurate and effective diagnosis and treatment of a variety of conditions because it allows high-resolution three-dimensional images to be acquired very quickly. However as the number of CT procedures performed globally have continued to increase; with growing concerns about patient protection. Currently, no system is in place to track patient doses and the lifetime cumulative dose from medical sources. The widespread use of CT even in developing countries has raised questions regarding the possible threat to public health especially in children. The best available risk estimates suggest that paediatric CT will result in significantly increased lifetime radiation risk over adult CT. Studies have shown that lower milliampere-second (mAs) settings can be used for children without significant loss of information. Although the risk–benefit balance is still strongly tilted toward benefit, there is still need for caution. Furthermore since the frequency of paediatric CT examinations is rapidly increasing, and estimates suggest that quantitative lifetime radiation risks for children are not negligible, efforts should be made toward more active reduction of CT exposure settings in paediatric patients. This article hopes to address this concerns and draw attention to the fact that children are not ‘small adults ’ and should therefore be treated differently. PMID:25161479

    Purpose - The purpose of this paper is to explore the experiences of staff in a large, public health service involved in transitioning support services to a shared services model. It aims to understand their perceptions of the benefits and risks arising from this change. Design/methodology/approach - Thematic analysis of qualitative data from semi-structured interviews with both service provider and customer agency staff was used to identify, analyze and report patterns of benefits and risks within data. Findings - Staff expressed the need for relevant subject-matter-experts to work within customer agencies to facilitate effective communication between the customer agency and shared services provider, reflecting observations found in out-sourcing literature. Research limitations/implications - Results point to significant challenges continuing to occur for shared services in healthcare. Risks identified suggest a more intimate relationship between clinical and support services than previously discussed. Originality/value - Previous discussion of the shared services model has not considered the skills, knowledge and ability required by staff in the customer agency. This research indicates that in the absence of such consideration, the concepts of the shared services model are weakened. PMID:27119396

    Background Although from a societal point of view a modal shift from car to bicycle may have beneficial health effects due to decreased air pollution emissions, decreased greenhouse gas emissions, and increased levels of physical activity, shifts in individual adverse health effects such as higher exposure to air pollution and risk of a traffic accident may prevail. Objective We describe whether the health benefits from the increased physical activity of a modal shift for urban commutes outweigh the health risks. Data sources and extraction We have summarized the literature for air pollution, traffic accidents, and physical activity using systematic reviews supplemented with recent key studies. Data synthesis We quantified the impact on all-cause mortality when 500,000 people would make a transition from car to bicycle for short trips on a daily basis in the Netherlands. We have expressed mortality impacts in life-years gained or lost, using life table calculations. For individuals who shift from car to bicycle, we estimated that beneficial effects of increased physical activity are substantially larger (3–14 months gained) than the potential mortality effect of increased inhaled air pollution doses (0.8–40 days lost) and the increase in traffic accidents (5–9 days lost). Societal benefits are even larger because of a modest reduction in air pollution and greenhouse gas emissions and traffic accidents. Conclusions On average, the estimated health benefits of cycling were substantially larger than the risks relative to car driving for individuals shifting their mode of transport. PMID:20587380

    Foot ulceration remains a serious health concern for diabetic patients and has a major impact on the cost of diabetes treatment. Early detection and preventive care, such as offloading or improved hygiene, can greatly reduce the risk of further complications. We aim to assess the use of hyperspectral tissue oximetry in predicting the risk of diabetic foot ulcer formation. Tissue oximetry measurements are performed during several visits with hyperspectral imaging of the feet in type 1 and 2 diabetes mellitus subjects that are at risk for foot ulceration. The data are retrospectively analyzed at 21 sites that ulcerated during the course of our study and an ulceration prediction index is developed. Then, an image processing algorithm based on this index is implemented. This algorithm is able to predict tissue at risk of ulceration with a sensitivity and specificity of 95 and 80%, respectively, for images taken, on average, 58 days before tissue damage is apparent to the naked eye. Receiver operating characteristic analysis is also performed to give a range of sensitivity/specificity values resulting in a Q-value of 89%.

    OBJECTIVE Optimal glycemic control slows diabetic retinopathy (DR) development and progression and is the standard of care for type 1 diabetes. However, these glycemic goals are difficult to achieve and sustain in clinical practice. The Renin Angiotensin System Study (RASS) showed that renin-angiotensin system (RAS) blockade can slow DR progression. In the current study, we evaluate whether glycemic control influenced the benefit of RAS blockade on DR progression in type 1 diabetic patients. RESEARCH DESIGN AND METHODS We used RASS data to analyze the relationships between two-steps or more DR progression and baseline glycemic levels in 223 normotensive, normoalbuminuric type 1 diabetic patients randomized to receive 5 years of enalapril or losartan compared with placebo. RESULTS A total of 147 of 223 patients (65.9%) had DR at baseline (47 of 74 patients [63.5%] in placebo and 100 of 149 patients [67.1%] in the combined treatment groups [P = 0.67]). Patients with two-steps or more DR progression had higher baseline A1C than those without progression (9.4 vs. 8.2%, P < 0.001). There was no beneficial effect of RAS blockade (P = 0.92) in patients with baseline A1C ≤7.5%. In contrast, 30 of 112 (27%) patients on the active treatment arms with A1C >7.5% had two-steps or more DR progression compared with 26 of 56 patients (46%) in the placebo group (P = 0.03). CONCLUSIONS RAS blockade reduces DR progression in normotensive, normoalbuminuric type 1 diabetic patients with A1C >7.5%. Whether this therapy could benefit patients with A1C ≤7.5% will require long-term studies of much larger cohorts. PMID:21715517

  4. Importance of cardiovascular disease risk management in patients with type 2 diabetes mellitus

    PubMed Central

    2014-01-01

    Type 2 diabetes mellitus (T2DM) is commonly accompanied by other cardiovascular disease (CVD) risk factors, such as hypertension, obesity, and dyslipidemia. Furthermore, CVD is the most common cause of death in people with T2DM. It is therefore of critical importance to minimize the risk of macrovascular complications by carefully managing modifiable CVD risk factors in patients with T2DM. Therapeutic strategies should include lifestyle and pharmacological interventions targeting hyperglycemia, hypertension, dyslipidemia, obesity, cigarette smoking, physical inactivity, and prothrombotic factors. This article discusses the impact of modifying these CVD risk factors in the context of T2DM; the clinical evidence is summarized, and current guidelines are also discussed. The cardiovascular benefits of smoking cessation, increasing physical activity, and reducing low-density lipoprotein cholesterol and blood pressure are well established. For aspirin therapy, any cardiovascular benefits must be balanced against the associated bleeding risk, with current evidence supporting this strategy only in certain patients who are at increased CVD risk. Although overweight, obesity, and hyperglycemia are clearly associated with increased cardiovascular risk, the effect of their modification on this risk is less well defined by available clinical trial evidence. However, for glucose-lowering drugs, further evidence is expected from several ongoing cardiovascular outcome trials. Taken together, the evidence highlights the value of early intervention and targeting multiple risk factors with both lifestyle and pharmacological strategies to give the best chance of reducing macrovascular complications in the long term.

    For five millennia, diabetes management has focused on controlling blood sugar and efforts to minimize the complications of this disease have depended on normalizing glucose. Since the 1970's, however, a growing awareness of the adverse effect of hypoglycemic agents on cardiac health has led to an increasing focus on the effect of diabetes management on cardiac risk. This was brought into focus in the early years of this century with issues around rosiglitazone and resulted in the United States Food and Drug Administration, mandating that new drug applications for diabetes include documentation of no adverse effect on cardiac health. We have recently reported on the potential benefit of SGLT-2 inhibitors in terms of glucose control; recent data suggesting a specific cardiac benefit of this class of agent have obligated us to update our understanding of this class of drugs. This review focuses, in general, on the increasing awareness of the effects of diabetes medications on cardiac health and, more specifically, on newer agents, including incretin-based therapies and SGLT-2 inhibitors.

    Type 2 diabetes mellitus is characterized by prolonged hyperinsulinemia, insulin resistance, and progressive hyperglycemia. Disease management relies on glycemic control through diet, exercise, and pharmacological intervention. The goal of the present study was to examine the effects of glycemic control and the use of glucose-lowering medication on the risk of breast, prostate, and colon cancer. Patients diagnosed with type 2 diabetes mellitus (N=9486) between 1 January 1995 and 31 December 2009 were identified and data on glycemic control (hemoglobin A1c, glucose), glucose-lowering medication use (insulin, metformin, sulfonylurea), age, BMI, date of diabetes diagnosis, insurance status, comorbidities, smoking history, location of residence, and cancer diagnoses were electronically abstracted. Cox proportional hazards regression modeling was used to examine the relationship between glycemic control, including medication use, and cancer risk. The results varied by cancer type and medication exposure. There was no association between glycemic control and breast or colon cancer; however, prostate cancer risk was significantly higher with better glycemic control (hemoglobin A1c ≤ 7.0%). Insulin use was associated with increased colon cancer incidence in women, but not with colon cancer in men or breast or prostate cancer risk. Metformin exposure was associated with reduced breast and prostate cancer incidence, but had no association with colon cancer risk. Sulfonylurea exposure was not associated with risk of any type of cancer. The data reported here support hyperinsulinemia, rather than hyperglycemia, as a major diabetes-related factor associated with increased risk of breast and colon cancer. In contrast, hyperglycemia appears to be protective in the case of prostate cancer. PMID:23962874

    Cardiovascular disease (CVD) is the most frequent cause of death in people with type 1 diabetes (T1D), despite modern advances in glycemic control and CVD risk factor modification. CVD risk identification is essential in this high-risk population, yet remains poorly understood. This review discusses the risk factors for CVD in young people with T1D, including hyperglycemia, traditional CVD risk factors (dyslipidemia, smoking, physical activity, hypertension), as well as novel risk factors such as insulin resistance, inflammation, and hypoglycemia. We present evidence that adverse changes in cardiovascular function, arterial compliance, and atherosclerosis are present even during adolescence in people with T1D, highlighting the need for earlier intervention. The methods for investigating cardiovascular risk are discussed and reviewed. Finally, we discuss the observational studies and clinical trials which have thus far attempted to elucidate the best targets for early intervention in order to reduce the burden of CVD in people with T1D.

  9. Selenium Health Benefit Values: Updated Criteria for Mercury Risk Assessments.

    Selenium (Se)-dependent enzymes (selenoenzymes) protect brain tissues against oxidative damage and perform other vital functions, but their synthesis requires a steady supply of Se. High methylmercury (CH3Hg) exposures can severely diminish Se transport across the placenta and irreversibly inhibit fetal brain selenoenzymes. However, supplemental dietary Se preserves their activities and thus prevents pathological consequences. The modified Se health benefit value (HBVSe) is a risk assessment criterion based on the molar concentrations of CH3Hg and Se present in a fish or seafood. It was developed to reflect the contrasting effects of maternal CH3Hg and Se intakes on fetal brain selenoenzyme activities. However, the original equation was prone to divide-by-zero-type errors whereby the calculated values increased exponentially in samples with low CH3Hg contents. The equation was refined to provide an improved index to better reflect the risks of CH3Hg exposures and the benefits provided by dietary Se. The HBVSe provides a biochemically based perspective that confirms and supports the FDA/EPA advice for pregnant and breast-feeding women regarding seafoods that should be avoided vs. those that are beneficial to consume. Since Se can be highly variable between watersheds, further evaluation of freshwater fish is needed to identify locations where fish with negative HBVSe may arise and be consumed by vulnerable subpopulation groups.

    of early glycemic control. Identifying high-risk patients at a very early stage is not only desired for prevention of diabetic retinopathy - neuropathy and nephropathy similarly remain frequent in type 1 diabetes. Early risk stratification will allow for timely implementation of effective interventions and for individualized screening and diabetes care. The second and third studies of this thesis provide the longest prospective studies to date on both retinal vessel calibers and retinal fractal dimensions and their predictive value on diabetic microvascular complications. Semi-automated computer software has been developed to measure smaller changes in the retinal vessels on retinal photographs. Two of the first parameters to be reliably estimated by these programs were retinal vessel calibers and retinal vascular fractal dimensions (a quantitative measure on vascular complexity). There is very limited knowledge on their predictive value on diabetic complications thus far. In the second and third study, a consistent relation between narrower retinal arteriolar calibers, wider retinal venular calibers, lower fractal dimensions and the 16-year incidences of diabetic neuropathy, nephropathy and proliferative retinopathy was found. This has never been shown before. The results on vessel analyzes provides indications of a common pathogenic pathway for diabetic microvascular complications and therefore a possibility of universal risk estimation for development of neuropathy, nephropathy and retinopathy in type 1 diabetes.

    Exposure to ambient air pollution (AP) exposure has been linked to type 2 diabetes (T2D) risk. Evidence on the impact of T2D genetic variants on AP susceptibility is lacking. Compared to single variants, joint genetic variants contribute substantially to disease risk. We investigated the modification of AP and diabetes association by a genetic risk score (GRS) covering 63 T2D genes in 1524 first follow-up participants of the Swiss cohort study on air pollution and lung and heart diseases in adults. Genome-wide data and covariates were available from a nested asthma case-control study design. AP was estimated as 10-year mean residential particulate matter <10μm (PM10). We computed count-GRS and weighted-GRS, and applied PM10 interaction terms in mixed logistic regressions, on odds of diabetes. Analyses were stratified by pathways of diabetes pathology and by asthma status. Diabetes prevalence was 4.6% and mean exposure to PM10 was 22μg/m(3). Odds of diabetes increased by 8% (95% confidence interval: 2, 14%) per T2D risk allele and by 35% (-8, 97%) per 10μg/m(3) exposure to PM10. We observed a positive interaction between PM10 and count-GRS on diabetes [ORinteraction=1.10 (1.01, 1.20)], associations being strongest among participants at the highest quartile of count-GRS [OR: 1.97 (1.00, 3.87)]. Stronger interactions were observed with variants of the GRS involved in insulin resistance [(ORinteraction=1.22 (1.00, 1.50)] than with variants related to beta-cell function. Interactions with count-GRS were stronger among asthma cases. We observed similar results with weighted-GRS. Five single variants near GRB14, UBE2E2, PTPRD, VPS26A and KCNQ1 showed nominally significant interactions with PM10 (P<0.05). Our results suggest that genetic risk for T2D may modify susceptibility to air pollution through alterations in insulin sensitivity. These results need confirmation in diabetes cohort consortia.

    Type 2 diabetes mellitus (T2DM) is a global public health problem of epidemic proportions, with 60–70% of affected individuals suffering from associated neurovascular complications that act on multiple organ systems. The most common and clinically significant neuropathies of T2DM include uremic neuropathy, peripheral neuropathy, and cardiac autonomic neuropathy. These conditions seriously impact an individual’s quality of life and significantly increase the risk of morbidity and mortality. Although advances in gene sequencing technologies have identified several genetic variants that may regulate the development and progression of T2DM, little is known about whether or not the variants are involved in disease progression and how these genetic variants are associated with diabetic neuropathy specifically. Significant missing heritability data and complex disease etiologies remain to be explained. This article is the first to provide a review of the genetic risk variants implicated in the diabetic neuropathies and to highlight potential commonalities. We thereby aim to contribute to the creation of a genetic-metabolic model that will help to elucidate the cause of diabetic neuropathies, evaluate a patient’s risk profile, and ultimately facilitate preventative and targeted treatment for the individual.

    Type 2 diabetes mellitus (T2DM) is a major and fast growing public health problem. Although obesity is considered to be the main driver of the pandemic of T2DM, a possible contribution of some environmental contaminants, of which persistent organic pollutants (POPs) form a particular class, has been suggested. POPs are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes which enable them to persist in the environment, to be capable of long-range transport, bio accumulate in human and animal tissue, bio accumulate in food chains, and to have potential significant impacts on human health and the environment. Several epidemiological studies have reported an association between persistent organic pollutants and diabetes risk. These findings have been replicated in experimental studies both in human (in-vitro) and animals (in-vivo and in-vitro), and patho-physiological derangements through which these pollutants exercise their harmful effect on diabetes risk postulated. This review summarizes available studies, emphasises on limitations so as to enable subsequent studies to be centralized on possible pathways and bring out clearly the role of POPs on diabetes risk.

Methodology A total of 54,670 patients with type 2 diabetes aged ≥25 years were selected from the Saudi National Diabetes Registry (SNDR) and analyzed for the presence of diabetic nephropathy. The American Diabetes Association (ADA) criterion was used to identify cases with microalbuminuria, macroalbuminuria and end stage renal disease (ESRD) for prevalence estimation and risk factor assessment. Results The overall prevalence of diabetic nephropathy was 10.8%, divided into 1.2% microalbuminuria, 8.1%macroalbuninuria and 1.5% ESRD. Age and diabetes duration as important risk factors have a strong impact on the prevalence of diabetic nephropathy, ranging from 3.7% in patients aged 25–44 years and a duration of >5 years, to 21.8% in patients ≥65 years with a diabetes duration of ≥15 years. Diabetes duration, retinopathy, neuropathy, hypertension, age >45 years, hyperlipidemia, male gender, smoking, and chronologically, poor glycemic control has a significantly high risk for diabetic nephropathy. Conclusion The prevalence of diabetic nephropathy is underestimated as a result of a shortage of screening programs. Risk factors related to diabetic nephropathy in this society are similar to other societies. There is thus an urgent need for screening and prevention programs for diabetic nephropathy among the Saudi population. PMID:24586457

    The success rate of organ transplantation has been increasing with advances in surgical and pharmacological techniques. However, the number of solid organ transplant recipients who require metabolic disease management is also growing. Post-transplant diabetes mellitus (PTDM) is a common complication after solid organ transplantation and is associated with risks of graft loss, cardiovascular morbidity, and mortality. Other risk factors for PTDM include older age, genetic background, obesity, hepatitis C virus infection, hypomagnesemia, and use of immunosuppressant agents (corticosteroids, calcineurin inhibitors, and mammalian target of rapamycin inhibitor). Management of PTDM should be started before the transplantation plan to properly screen high-risk patients. Even though PTDM management is similar to that of general type 2 diabetes, therapeutic approaches must be made with consideration of drug interactions between immunosuppressive agents, glucose-lowering medications, and graft rejection and function.

    Purpose Gestational diabetes mellitus (GDM) continues to be a significant health disorder triggering harmful complications in pregnant women and fetuses. Our knowledge of GDM epidemiology in Yemen is largely based on very limited data. The aim of this study was, therefore, to determine the prevalence and risk factors of GDM among pregnant women in Dhamar governorate, Yemen. Patients and methods A total of 311 subjects were randomly selected for this cross sectional survey. Health history data and blood samples were collected using a pretested questionnaire. To determine the prevalence of GDM, the fasting and random blood glucose techniques were applied according to the recommendations of the American Diabetes Association, using alternative methods that are more convenient to the targeted population. Poisson’s regression model incorporating robust sandwich variance was utilized to assess the association of potential risk factors in developing GDM. Results The prevalence of GDM was found to be 5.1% among the study population. Multivariate analysis confirmed age ≥30 years, previous GDM, family history of diabetes, and history of polycystic ovary syndrome as independent risk factors for GDM prevalence. However, body mass index ≥30 kg/m2 and previous macrosomic baby were found to be dependent risk factors. Conclusion This study reports new epidemiological information about the prevalence and risk factors of GDM in Yemen. Introduction of proper maternal and neonatal medical care and health education are important in order to save the mother and the baby. PMID:26869814

    Fracture risk is significantly increased in both type 1 and type 2 diabetes, and individuals with diabetes experience worse fracture outcomes than normoglycemic individuals. Factors that increase fracture risk include lower bone mass in type 1 diabetes and compromised skeletal quality and strength despite preserved bone density in type 2 diabetes, as well as the effects of comorbidities such as diabetic macro- and microvascular complications. In this Perspective, we assess the developing scientific knowledge regarding the epidemiology and pathophysiology of skeletal fragility in patients with diabetes and the emerging data on the prediction, treatment, and outcomes of fractures in individuals with type 1 and type 2 diabetes.

  18. Cervical removal at hysterectomy for benign disease. Risks and benefits.

    PubMed

    Hasson, H M

    1993-10-01

    An assessment of the risks and benefits of total and subtotal hysterectomy for benign disease was performed using the published literature, including a MEDLINE search, on all studies dealing with hysterectomy and related topics from 1946 to 1992. The shift from subtotal to total hysterectomy occurred before cytologic screening was accepted. Currently, SIL is diagnosed by cytology, evaluated by colposcopy and treated preferentially with cone biopsy. Prophylactic removal of the cervix does not eliminate the risk of cancer: it may shift the risk to the vaginal epithelium. The cervix has a role in sexual arousal and orgasm, probably due to stimulation of the Frankenhauser uterovaginal plexus. Bladder and bowel dysfunction following total hysterectomy may be related to loss of nerve ganglia closely associated with the cervix. Increased operative and postoperative morbidity, vaginal shortening, vault prolapse, abnormal cuff granulations and oviductal prolapse are other disadvantages of total hysterectomy. The cervix is not a useless organ and should not be removed during hysterectomy without a proper indication. PMID:8263867

    COPD is a chronic disease and, like many other chronic diseases, there is no treatment to reverse the severity of the disease except for lung transplant. To date, no inhaled medications have been shown to improve survival. Tiotropium bromide is a long-acting inhaled anticholinergic drug for the treatment of COPD that can improve lung function, reduce symptoms and exacerbations, and improve quality of life with once-daily dosing. It was initially approved and marketed in several countries in Europe in 2002 and then approved in the US in 2004. Tiotropium is generally well tolerated with dry mouth being the main adverse effect. Other adverse effects include constipation, tachycardia, blurred vision, urinary retention and increased intraocular pressure. Despite the recently raised concerns about an excess risk of cardiovascular adverse events with inhaled anticholinergic agents, the risk/benefit ratio of tiotropium appears still favorable given the favorable safety profile demonstrated in the UPLIFT study. However, caution should be advised in patients at high risk for cardiovascular disease given the paucity of data in such patients. PMID:19281075

    This concise review presents two Cochrane Reviews undertaken to determine: (1) the relative effectiveness of fluoride toothpastes of different concentrations in preventing dental caries in children and adolescents; and (2) the relationship between the use of topical fluorides in young children and their risk of developing dental fluorosis. To determine the relative effectiveness of fluoride toothpastes of different concentrations, we undertook a network meta-analysis utilizing both direct and indirect comparisons from randomized controlled trials (RCTs). The review examining fluorosis included evidence from experimental and observational studies. The findings of the reviews confirm the benefits of using fluoride toothpaste, when compared with placebo, in preventing caries in children and adolescents, but only significantly for fluoride concentrations of 1000 ppm and above. The relative caries-preventive effects of fluoride toothpastes of different concentrations increase with higher fluoride concentration. However, there is weak, unreliable evidence that starting the use of fluoride toothpaste in children under 12 months of age may be associated with an increased risk of fluorosis. The decision of what fluoride levels to use for children under 6 years should be balanced between the risk of developing dental caries and that of mild fluorosis. PMID:21248357

    The relative cost-effectiveness of different treatment strategies for hormone replacement therapy (HRT) was assessed within the framework of a computer model. Where data were lacking, it was necessary to make assumptions about the effects of HRT, particularly in relation to combined oestrogen-progestogen therapy and cardiovascular disease; however, sensitivity analyses were performed to assess the impact of changing these assumptions on the cost-effectiveness equation. It appears that net expenditure by the NHS will depend critically on the direct costs of treatment, rather than on any indirect costs incurred or saved as a result of side-effects. In terms of mortality, a reduction in cardiovascular disease risk would have greatest impact and would overshadow any small increase in breast cancer risk which may be associated with long-term use. If the cardioprotective effect of oestrogen is real, our results suggest that long-term prophylactic treatment of hysterectomised women would be relatively cost-effective. Treatment of symptomatic menopausal women for any period of time appears to offer very good value for money. The lack of data relating to combined oestrogen-progestogen therapy and cardioprotection, and the major importance of the latter in the equation of benefits and risks, make it more difficult to draw conclusions about the cost-effectiveness of treating non-hysterectomised asymptomatic women for prophylactic reasons.

    AIM: To establish a link between the risk of diabetes with haemoglobinopathies by examining available evidence of the effects of iron and blood glucose homeostasis from molecular to epidemiological perspectives. METHODS: A systematic literature search was performed using electronic literature databases using various search terms. The International Diabetes Federation World Atlas was used to generate a list of populations with high rates of diabetes. PubMed, Scopus and Google Scholar were used to identify which of these populations also had a reported prevalence of haemoglobin abnormalities. RESULTS: Abnormalities in iron homeostasis leads to increases in reactive oxygen species in the blood. This promotes oxidative stress which contributes to peripheral resistance to insulin in two ways: (1) reduced insulin/insulin receptor interaction; and (2) β-cell dysfunction. Hepcidin is crucial in terms of maintaining appropriate amounts of iron in the body and is in turn affected by haemoglobinopathies. Hepcidin also has other metabolic effects in places such as the liver but so far the extent of these is not well understood. It does however directly control the levels of serum ferritin. High serum ferritin is found in obese patients and those with diabetes and a meta-analysis of the various studies shows that high serum ferritin does indeed increase diabetes risk. CONCLUSION: From an epidemiological standpoint, it is plausible that the well-documented protective effects of haemoglobinopathies with regard to malaria may have also offered other evolutionary advantages. By contributing to peripheral insulin resistance, haemoglobinopathies may have helped to sculpt the so-called “thrifty genotype”, which hypothetically is advantageous in times of famine. The prevalence data however is not extensive enough to provide concrete associations between diabetes and haemoglobinopathies - more precise studies are required. PMID:26788262

    A vegetarian diet may be adopted for various reasons that can include ecological, economic, religious, ethical and health considerations. In the latter case they arise from the desire to lose weight, in tackling obesity, improving physical fitness and/or in reducing the risk of acquiring certain diseases. It has been shown that properly applied vegetarian diet is the most effective way of reducing body mass (expressed as BMI), improving the plasma lipid profile and in decreasing the incidence of high arterial blood pressure, cardiovascular disease, stroke, metabolic syndrome and arteriosclerosis. In addition, improved insulin sensitivity together with lower rates of diabetes and cancer has been observed. Some studies have however found that a vegetarian diet may result in changes adversely affecting the body. These could include; hyperhomocysteinaemia, protein deficiency, anaemia, decreased creatinine content in muscles and menstrual disruption in women who undertake increased physical activity. Some of these changes may decrease the ability for performing activities that require physical effort. Nevertheless, on balance it can be reasonably concluded that the beneficial effects of a vegetarian diet significantly, by far, outweigh the adverse ones. It should also be noted that the term 'vegetarian diet' is not always clearly defined in the literature and it may include many dietary variations. PMID:24964573

    Objective The purpose of this study was to estimate the ratio of cancers prevented to induced (benefit-risk ratio) for CT colonography screening every five years from age 50-80. Materials and methods Radiation-related cancer risk was estimated using risk projection models based on the National Research Council's BEIR VII committee's report and screening protocols from the American College of Radiology Imaging Network's National CT Colonography Trial. Uncertainty limits (UL) were estimated using Monte-Carlo simulation methods. Comparative modelling with three colorectal cancer microsimulation models was used to estimate the potential reduction in colorectal cancer cases and deaths. Results The estimated mean effective dose per CT colonography screen was 8mSv for females and 7mSv for males. The estimated number of radiation-related cancers from CT colonography screening every 5 years from age 50-80 was 150 cases/100,000 individuals (95%UL:80-280) for males and females. The estimated number of colorectal cancers prevented by CT colonography every 5 years from age 50-80 ranged across the three microsimulation models from 3580 to 5190/100,000, yielding a benefit-risk ratio that varied from 24:1(95%UL=13:1-45:1) to 35:1(95%UL=19:1-65:1). The benefit-risk ratio for cancer deaths was even higher than the ratio for cancer cases. Inclusion of radiation-related cancer risks from CT scans following-up extracolonic findings did not materially alter the results. Conclusions Concerns have been raised about recommending CT colonography as a routine screening tool because of the potential harms, including the radiation risks. Based on these models the benefits from CT colonography screening every five years from age 50-80 clearly outweigh the radiation risks. PMID:21427330

    In the USA, compared to whites, African-Americans are disproportionately impacted by the diabetes epidemic. Traditional diabetes risk factors, such as obesity, are more common among African-Americans, but these traditional risk factors do not explain all of the disparity in diabetes risk. Recent research has identified novel environmental, lifestyle, physiologic, and genetic risk factors for diabetes, some of which appear to impact African-Americans more than whites. This manuscript reviews the recent literature to highlight some of these novel risk factors that may be contributing to the racial disparity in diabetes risk. Further study is needed of the modifiable risk factors for development of interventions to reduce the risk of diabetes in African-Americans, as well as other high-risk populations. PMID:26458374

    In the U.S., Latinos experience disproportionately higher rates of type 2 diabetes and diabetes-related complications than non-Latino whites. Sugar-sweetened beverage (SSB) consumption is strongly associated with increased risk of developing type 2 diabetes. Reducing caloric intake, particularly from energy-dense, low-nutrient foods or beverages, can be an effective and key strategy for metabolic and weight control. However, little is known about the contribution of various types of beverages, including but not limited to SSBs, to total caloric intake among Latinos with type 2 diabetes. Low-income Latinos (87.7% Puerto Rican) participating in a diabetes self-management intervention trial (N=238) provided cross-sectional, descriptive data on beverage consumption patterns, anthropometric outcomes, and metabolic characteristics. Beverages accounted for one-fifth of the total daily caloric intake. SSBs and milk beverages, respectively, contributed 9.6% of calories to overall daily caloric intake. Interventions directed at diabetes risk factors among low-income Latinos with diabetes may benefit from consideration of beverage consumption behaviors as an important strategy to reduce caloric and sugar intake.

    Summary Diabetes mellitus was identified as a risk factor for developing tuberculosis (TB) infection, and relapse after therapy. The risk of acquiring TB is described as comparable to that of HIV population. The fact that diabetics are 3× times more prone to develop pulmonary TB than nondiabetics cannot be overlooked. With DM recognized as global epidemic, and TB affecting one-third of the world population, physicians must remain vigilant. We present a 45-year-old woman born in Dominican Republic (DR), with 10-year history of T2DM treated with metformin, arrived to our Urgency Room complaining of dry cough for the past 3months. Interview unveiled unintentional 15lbs weight loss, night sweats, occasional unquantified fever, and general malaise but denied bloody sputum. She traveled to DR 2years before, with no known ill exposure. Physical examination showed a thin body habitus, otherwise well appearing woman with stable vital signs, presenting solely right middle lung field ronchi. LDH, ESR, hsCRP and Hg A1C were elevated. Imaging revealed a right middle lobe cavitation. Sputum for AFB disclosed active pulmonary TB. Our case portrays that the consideration of TB as differential diagnosis in diabetics should be exercised with the same strength, as it is undertaken during the evaluation of HIV patients with lung cavitation. Inability to recognize TB will endanger the patient, hospital dwellers and staff, and perpetuate this global public health menace. Learning points Diabetes mellitus should be considered an important risk factor for the reactivation of pulmonary tuberculosis. High clinical suspicious should be taken into consideration as radiological findings for pulmonary tuberculosis in patients with diabetes mellitus may be atypical, involving middle and lower lobes. Inability to recognize pulmonary tuberculosis will endanger the patient, hospital dwellers and staff, and perpetuate this global public health menace. PMID:27482384

    We conducted a case-control study to investigate the association between GSTM1, GSTT1 and GSTP1 IIe105Val polymorphisms and development of gestational diabetes mellitus in a Chinese population. A total of 320 patients with gestational diabetes mellitus and 358 pregnancy subjects were consecutively collected between January 2013 and December 2014. Genotyping for detection of GSTM1, GSTT1 and GSTP1 IIe105Val was conducted by using PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphisms) method. By Fisher’s exact test, we found that the genotype distributions of GSTP1 IIe105Val were in line with the Hardy-Weinberg equilibrium in control subjects (P=0.57). By Chi-square test, we found significant differences in the genotype distributions of GSTM1 (χ2=11.49, P=0.001) and GSTT1 (χ2=18.50, P<0.001). Using unconditional logistic analysis, individuals carrying the null genotypes of GSTM1 and GSTT1 were associated with an increased risk of gestational diabetes mellitus when compared with the present genotype, and the adjusted Ors (95% CI) were 1.71 (1.24-2.36) and 2.00 (1.44-2.79), respectively. However, the GSTP1 IIe105Val polymorphism was not associated with an elevated risk of gestational diabetes mellitus. In conclusion, we suggest that the GSTM1 null genotype and GSTT1 null genotype are correlated with an increased risk of gestational diabetes mellitus in a Chinese population. PMID:26823865

    Introduction: Diabetes is a group of metabolic diseases characterized by hyperglycemia, and represents a disease of the modern age, disease of the 21st century. Prevention of this disease is listed as imperative. Aim of this article was to evaluate questionnaires on the assessment of risk factors for Diabetes Mellitus type 2. Material and Methods: A total of 540 questionnaires handed out randomly to citizens of Canton Sarajevo of all ages, sexes and educational levels (in January 2016) were analyzed. Results: Analyzed questionnaires showed relatively low risk of getting diabetes in the next ten years in the majority of the population. These results are rather encouraging but may in some way be in confrontation with the statistics which show a rapid outburst of diabetes. Conclusion: The life-style is the main reason for such a thing to happen, and looking at these questionnaires, we might get the feeling that we really do live in a, conditionally speaking, physically active society. That, from our everyday experience is not entirely true. It would be wise to continue doing research on this topic on the territory of Bosnia and Herzegovina. PMID:27482159

    The purpose of this study was to examine characteristics associated with the insulin metabolic syndrome, including insulin resistance, abnormal glucose tolerance, dyslipidemia, obesity, and elevated blood pressure, among women who have experienced gestational diabetes. 39 nondiabetic, young (20-42 years), postpartum (3-18 months) white women were recruited from obstetrical clinics. Twenty-one women had a history of gestational diabetes; 18 had uncomplicated pregnancies. Multivariate analyses revealed a significant difference between groups in insulin resistance (M, measured by euglycemic clamp) and insulin levels (from an oral glucose tolerance test), with insulin resistance showing a statistically stronger difference than insulin levels. Groups also differed significantly when compared on a set of variables associated with insulin metabolic syndrome: glucose tolerance, triglycerides, blood pressure, and body-mass index. Using insulin resistance as a covariate eliminated these group differences, suggesting that insulin resistance is the key factor underlying insulin metabolic syndrome. The higher risk of later developing type 2 diabetes and hypertension in women who have a history of gestational diabetes is explicable by their poorer profile on variables associated with insulin metabolic syndrome, and appears to be attributable to insulin resistance. Thus, insulin resistance appears to distinguish young women at risk for cardiovascular disease. PMID:10616862

    Purpose The purpose of this article was to summarize scientific knowledge from an expert panel on reproductive health among adolescents with type 2 diabetes (T2D). Methods Using a mental model approach, a panel of experts—representing perspectives on diabetes, adolescents, preconception counseling, and reproductive health—was convened to discuss reproductive health issues for female adolescents with T2D. Results Several critical issues emerged. Compared with adolescents with type 1 diabetes, (1) adolescents with T2D may perceive their disease as less severe and have less experience managing it, putting them at risk for complications; (2) T2D is more prevalent among African Americans, who may be less trusting of the medical establishment; (3) T2D is associated with obesity, and it is often difficult to change one’s lifestyle within family environments practicing sedentary and dietary behaviors leading to obesity; (4) teens with T2D could be more fertile, because obesity is related to earlier puberty; (5) although obese teens with T2D have a higher risk of polycystic ovary syndrome, which is associated with infertility, treatment with metformin can increase fertility; and (6) women with type 2 diabetes are routinely transferred to insulin before or during pregnancy to allow more intensive management. Conclusions Findings from the expert panel provide compelling reasons to provide early, developmentally appropriate, culturally sensitive preconception counseling for teens with T2D. PMID:20944055

  12. Long-term depot antipsychotics. A risk-benefit assessment.

    PubMed

    Barnes, T R; Curson, D A

    1994-06-01

    The main advantage of depot antipsychotic medication is that it overcomes the problem of covert noncompliance. Patients receiving depot treatment who refuse their injection or fail to receive it for any other reason can be immediately identified and appropriate action taken. In the context of a carefully monitored management programme, depot treatment can have a major impact on compliance and, consequently, the risk of relapse and hospitalisation can be reduced. Another major advantage is that the considerable individual variation in bioavailability and metabolism with oral antipsychotic drugs is markedly reduced with depot treatment. A better correlation between the dose administered and the concentration of medication found in blood or plasma is achieved with depot treatment, and thus, the clinician has greater control over the amount of drug being delivered to the site of activity. A further benefit of depot treatment is the achievement of stable plasma concentrations over long periods, allowing injections to be given every few weeks. However, this also represents a potential disadvantage in that there is a lack of flexibility of administration. Should adverse effects develop, the drug cannot be rapidly withdrawn. Furthermore, adjustment to the optimal dose becomes a long term strategy. The controlled studies of low dose maintenance therapy with depot treatment suggest that it can take months or years for the consequences of dose reduction, in terms of increased risk of relapse, to become manifest. When weighing up the risks and benefits of long term antipsychotic treatment for the individual patient with schizophrenia, the clinician must take into account the nature, severity and frequency of past relapses, and the degree of distress and disability related to any adverse effects. However, the clinical decision to prescribe either a depot or an oral antipsychotic for maintenance treatment will probably rest largely on an assessment of the risk of poor compliance

    We evaluate, for the U.S. case, the costs and benefits of three security measures designed to reduce the likelihood of a direct replication of the 9/11 terrorist attacks. To do so, we assess risk reduction, losses, and security costs in the context of the full set of security layers. The three measures evaluated are installed physical secondary barriers (IPSB) to restrict access to the hardened cockpit door during door transitions, the Federal Air Marshal Service (FAMS), and the Federal Flight Deck Officer (FFDO) Program. In the process, we examine an alternate policy measure: doubling the budget of the FFDO program to $44 million per year, installing IPSBs in all U.S. aircraft at a cost of $13.5 million per year, and reducing funding for FAMS by 75% to $300 million per year. A break-even cost-benefit analysis then finds the minimum probability of an otherwise successful attack required for the benefit of each security measures to equal its cost. We find that the IPSB is costeffective if the annual attack probability of an otherwise successful attack exceeds 0.5% or one attack every 200 years. The FFDO program is costeffective if the annual attack probability exceeds 2%. On the other hand, more than two otherwise successful attacks per year are required for FAMS to be costeffective. A policy that includes IPSBs, an increased budget for FFDOs, and a reduced budget for FAMS may be a viable policy alternative, potentially saving hundreds of millions of dollars per year with consequences for security that are, at most, negligible.

  14. Nitroglycerin Use in Myocardial Infarction Patients: Risks and Benefits

    PubMed Central

    Ferreira, Julio C.B.; Mochly-Rosen, Daria

    2012-01-01

    Acute myocardial infarction and its sequelae are leading causes of morbidity and mortality worldwide. Nitroglycerin remains a first-line treatment for angina pectoris and acute myocardial infarction. Nitroglycerin achieves its benefit by giving rise to nitric oxide, which causes vasodilation and increases blood flow to the myocardium. However, continuous delivery of nitroglycerin results in tolerance, limiting the use of this drug. Nitroglycerin tolerance is due, at least in part, to inactivation of aldehyde dehydrogenase 2 (ALDH2), an enzyme that converts nitroglycerin to the vasodilator, nitric oxide. We have recently found that, in addition to nitroglycerin’s effect on the vasculature, sustained treatment with nitroglycerin negatively affects cardiomyocyte viability following ischemia, thus resulting in increased infarct size in a myocardial infarction model in animals. Co-administration of Alda-1, an activator of ALDH2, with nitroglycerin improves metabolism of reactive aldehyde adducts and prevents the nitroglycerin-induced increase in cardiac dysfunction following myocardial infarction. In this review, we describe the molecular mechanisms associated with the benefits and risks of nitroglycerin administration in myocardial infarction. (167 of 200). PMID:22040938

    Recent studies in both humans and animals suggest that air pollution is an important risk factor for type 2 diabetes mellitus (T2DM). However, the mechanism by which air pollution mediates propensity to diabetes is not fully understood. While a number of epidemiologic studies have shown a positive association between ambient air pollution exposure and risk for T2DM, some studies have not found such a relationship. Experimental studies in susceptible disease models do support this association and suggest the involvement of tissues involved in the pathogenesis of T2DM such as the immune system, adipose, liver, and central nervous system. This review summarizes the epidemiologic and experimental evidence between ambient outdoor air pollution and T2DM. PMID:25628401

Although the risk of diabetes is mainly associated with increased BMI close to the time of diagnosis, the risk of coronary heart disease is associated with an elevated BMI both in adolescence and in adulthood, supporting the hypothesis that the processes causing incident coronary heart disease, particularly atherosclerosis, are more gradual than those resulting in incident diabetes.

    We investigated the relation between fibrocalculous pancreatic diabetes and cassava consumption in a case-control study, in which 31 cases of pancreatic diabetes were compared with 45 non-diabetic control subjects who had no pancreatic calcification. Risk of diabetes was not related to cassava consumption. We also observed no increased risk of fibrocalculous pancreatic diabetes associated with alcohol consumption, history of gallbladder and biliary tract diseases, ascariasis, and family history of diabetes. Lower monthly income, farmer occupation, rural residence, and low BMI were significantly (p less than 0.05) related to pancreatic diabetes. Our data suggest that consumption of cassava may not be an important risk factor for pancreatic diabetes. With limited sample size, however, cassava consumption could not be excluded as one possible cause of fibrocalculous pancreatic diabetes. PMID:2976643

    Large differences in climate outcomes are projected over the coming century depending on whether greenhouse gas emissions continue on a business as usual path or are substantially reduced following an aggressive mitigation strategy. However, it has previously been claimed that it will take many decades for there to be any significant difference between paths of aggressive mitigation and business as usual with the emergence of differences only seen towards the middle of the century. Here we show that important differences in our exposure to risk of climate extremes in many land regions emerges much more quickly. Without substantial mitigation, in many regions of the world, extreme (one in 20-year) seasonal, regional near surface air temperatures are found to have become more than twice as likely within only 15 years (i.e. by 2030). Therefore our exposure to climate risk is reduced substantially and rapidly with aggressive mitigation. This demonstrates that the benefits of mitigation are realised rapidly and it is not necessary to wait until the middle of the century as has previously been claimed.

  20. Modern obesity pharmacotherapy: weighing cardiovascular risk and benefit.

    Cunningham, Jonathan W; Wiviott, Stephen D

    2014-11-01

    Obesity is a major correlate of cardiovascular disease. Weight loss improves cardiovascular risk factors and has the potential to improve outcomes. Two drugs, phentermine plus topiramate and lorcaserin, have recently been approved by the US Food and Drug Administration for the indication of obesity; a third, bupropion plus naltrexone, is under consideration for approval. In clinical trials, these drugs cause weight loss and improve glucose tolerance, lipid profile, and, with the exception of bupropion plus naltrexone, blood pressure. However, their effect on cardiovascular outcomes is unknown. In defining appropriate roles for these drugs in preventive cardiology, it is important to remember the checkered history of drugs for obesity. New weight-loss drugs share the serotonergic and sympathomimetic mechanisms that proved harmful in the cases of Fen-Phen and sibutramine, respectively, albeit with significant differences. Given these risks, randomized cardiovascular outcomes trials are needed to establish the safety, and potential benefit, of these drugs. This review will discuss the history of pharmacotherapy for obesity, existing efficacy and safety data for the novel weight-loss drugs, and issues in the design of postapproval clinical trials.

    Despite the increasing epidemic of diabetes mellitus affecting populations at different life stages, the global burden of gestational diabetes mellitus (GDM) is not well assessed. Systematically synthesized data on global prevalence estimates of GDM are lacking, particularly among developing countries. The hyperglycemic intrauterine environment as exemplified in pregnancies complicated by GDM might not only reflect but also fuel the epidemic of type 2 diabetes mellitus (T2DM). We comprehensively reviewed available data in the past decade in an attempt to estimate the contemporary global prevalence of GDM by country and region. We reviewed the risk of progression from GDM to T2DM as well. Synthesized data demonstrate wide variations in both prevalence estimates of GDM and the risk of progression from GDM to T2DM. Direct comparisons of GDM burden across countries or regions are challenging given the great heterogeneity in screening approaches, diagnostic criteria, and underlying population characteristics. In this regard, collaborative efforts to estimate global GDM prevalence would be a large but important leap forward. Such efforts may have substantial public health implications in terms of informing health policy makers and healthcare providers for disease burden and for developing more targeted and effective diabetes prevention and management strategies globally.

    This project utilized a cross-sectional study design to assess diabetes risk among 540 individuals from 12 counties using trained extension agents and community organizations in West Virginia. Individuals were screened for diabetes using (1) the validated 7-item diabetes risk assessment survey and (2) hemoglobin A1c tests. Demographic and lifestyle behaviors were also collected. The average age, body mass index, and A1c were 51.2 ± 16.4, 31.1 ± 7.5, and 5.8 ± 0.74, respectively. The majority were females, Non-Hispanic Whites with no prior diagnosis of diabetes. Screenings showed that 61.8% of participants were at high risk for diabetes. Family history of diabetes (siblings or parents), overweight or obese status, sedentary lifestyle, and older age were commonly prevalent risk factors. Higher risk scores computed from the 7-item questions correlated positively with higher A1c (r = 0.221, P < 0.001). In multivariate logistic regression analyses, higher diabetes risk was predicted by obesity, older age, family history of hypertension, and gestational diabetes. Females were 4 times at higher risk than males. The findings indicated that community-based screenings were an effective way to assess diabetes risk in rural West Virginia. Linking diabetes screenings with referrals to lifestyle programs for high risk individuals can help reduce the burden of diabetes in the state. PMID:26881242

    Background Diabetes self-management education has been shown to be effective in controlled trials. However, few programs that meet American Association of Diabetes Educators standards have been translated into widespread practice. Objective This study examined the translation of the evidence-based Better Choices, Better Health-Diabetes program in both Internet and face-to-face versions. Methods We administered the Internet program nationally in the United States (n=1010). We conducted face-to-face workshops in Atlanta, Georgia; Indianapolis, Indiana; and St. Louis, Missouri (n=232). Self-report questionnaires collected health indicator, health behavior, and health care utilization measures. Questionnaires were administered on the Web or by mail. We determined hemoglobin A1c (HbA1c) from blood samples collected via mailed kits. Paired t tests determined whether changes between baseline and 6 months differed significantly from no change. Subgroup analyses determined whether participants with specific conditions benefited (high HbA1c, depression, hypoglycemia, nonadherence to medication taking, and no aerobic exercise). We calculated the percentage of participants with improvements of at least 0.4 effect size in at least one of the 5 above measures. Results Of the 1242 participants, 884 provided 6-month follow-up questionnaires. There were statistically significant improvements in 6 of 7 health indicators (including HbA1c) and in 7 of 7 behaviors. For each of the 5 conditions, there were significant improvements among those with the condition (effect sizes 0.59–1.1). A total of 662 (75.0%) of study participants improved at least 0.4 effect size in at least one criterion, and 327 (37.1%) improved in 2 or more. Conclusions The Diabetes Self-Management Program, offered in two modes, was successfully disseminated to a heterogeneous national population of members of either insured or administered health plans. Participants had small but significant benefits in multiple

    A recent international meeting was convened by two United Nations bodies to focus on international collaboration on clinical appropriateness/referral guidelines for use in medical imaging. This paper, the second of 4 from this technical meeting, addresses barriers to the successful development/deployment of clinical imaging guidelines and means of overcoming them. It reflects the discussions of the attendees, and the issues identified are treated under 7 headings: ■ Practical Strategy for Development and Deployment of Guidelines; ■ Governance Arrangements and Concerns with Deployment of Guidelines; ■ Finance, Sustainability, Reimbursement, and Related Issues; ■ Identifying Benefits and Radiation Risks from Radiological Examinations; ■ Information Given to Patients and the Public, and Consent Issues; ■ Special Concerns Related to Pregnancy; and ■ The Research Agenda. Examples of topics identified include the observation that guideline development is a global task and there is no case for continuing it as the project of the few professional organizations that have been brave enough to make the long-term commitment required. Advocacy for guidelines should include the expectations that they will facilitate: (1) better health care delivery; (2) lower cost of that delivery; with (3) reduced radiation dose and associated health risks. Radiation protection issues should not be isolated; rather, they should be integrated with the overall health care picture. The type of dose/radiation risk information to be provided with guidelines should include the uncertainty involved and advice on application of the precautionary principle with patients. This principle may be taken as an extension of the well-established medical principle of "first do no harm." PMID:25652302

    There is an ongoing debate about equity and equality in health care, and whether immigrants benefit equally from services as the non-immigrant population. The study focuses on benefits from and adherence to the diabetes mellitus type 2 (DM 2) disease management program (DMP) among Turkish immigrants in Germany. So far, it has not been researched whether this group benefits from enrollment in the DMP as well as diabetics from the non-immigrant population. Data on the non-immigrant sample (N = 702) stem from a survey among members of a German health insurance, the Turkish immigrant sample (N = 102) was recruited in the area of Hamburg. Identical questions in both surveys enable comparing major components. Regarding process quality, Turkish diabetics do not differ from the non-immigrant sample; moreover, they have significantly more often received documentation and diabetes training. In terms of outcome quality however, results display a greater benefit on behalf of the non-immigrant sample (e.g., blood parameters and body mass index), and they also met more of the DMP criteria. This underlines the need of diabetics with Turkish background for further education and information in order to become the empowered patient as is intended by the DMP as well as to prevent comorbidities.

    Methodologic biases may explain why observational studies examining metformin use in relation to lung cancer risk have produced inconsistent results. We conducted a cohort study to further investigate this relationship, accounting for potential biases. For 47,351 patients with diabetes aged ≥40 years, who completed a health-related survey administered between 1994 and 1996, data on prescribed diabetes medications were obtained from electronic pharmacy records. Follow-up for incident lung cancer occurred from January 1, 1997, until June 30, 2012. Using Cox regression, we estimated lung cancer risk associated with new use of metformin, along with total duration, recency, and cumulative dose (all modeled as time-dependent covariates), adjusting for potential confounding factors. During 428,557 person-years of follow-up, 747 patients were diagnosed with lung cancer. No association was found with duration, dose, or recency of metformin use and overall lung cancer risk. Among never smokers, however, ever use was inversely associated with lung cancer risk (hazard ratio (HR) 0.57; 95% confidence interval (CI), 0.33-0.99), and risk appeared to decrease monotonically with longer use (≥5 years: HR, 0.48; 95% CI, 0.21-1.09). Among current smokers, corresponding risk estimates were >1.0, although not statistically significant. Consistent with this variation in effect by smoking history, longer use was suggestively associated with lower adenocarcinoma risk (HR, 0.69; 95% CI, 0.40-1.17), but higher small cell carcinoma risk (HR, 1.82; 95% CI, 0.85-3.91). In this population, we found no evidence that metformin use affects overall lung cancer risk. The observed variation in association by smoking history and histology requires further confirmation.

    2010-05-01

    Land use and land management on floodplains have increasingly come into focus, particularly in relation to their impact on flooding. To date, research and modelling has explored the impact of land use changes such as floodplain afforestation, changes to management of upland moorlands or re-establishment of wet meadows on floodplains. However, no such investigation has been carried out into the impact on floodplain flows of growing energy crops. In the UK, a strong emphasis is being given to promotion of renewable energy. Farmers are encouraged to plant energy crops such as Miscanthus or Short Rotation Crops (e.g. Willow) in suitable locations, which typically exclude farmland in Flood Zone 3 (i.e. areas likely to be flooded by an event with a 100-year return period). However, there is a lack of understanding as to what impact, if any, the dense character of these crops planted on floodplains might have on flooding. This gap in knowledge currently prevents energy crops from being planted in areas where they could provide high economic and environmental benefit, and even possibly contribute to flood mitigation. At present, no guidance or policy exists to advise whether allowing farmers to establish energy crop plantations in Flood Zone 3 could alter the existing flood risk. Consequently, if energy crops could provide a coupled benefit of renewable energy source and flood mitigation, this benefit is not being utilised. To help fill in this gap in knowledge, a short term project was carried out in order to investigate, using suitable hydraulic modelling, the possible scale of impact of growing energy crops on river and floodplain flows, flood depth and overall impact on flood risk locally as well as downstream. 2D hydraulic modelling using TUFLOW was deemed to be the most appropriate approach for these investigations. The methodology included gaining an understanding of the life cycle and planting regime of Miscanthus and Willow, review of current knowledge on the

  9. A School-Based Intervention for Diabetes Risk Reduction

    2010-01-01

    BACKGROUND We examined the effects of a multicomponent, school-based program addressing risk factors for diabetes among children whose race or ethnic group and socioeconomic status placed them at high risk for obesity and type 2 diabetes. METHODS Using a cluster design, we randomly assigned 42 schools to either a multicomponent school-based intervention (21 schools) or assessment only (control, 21 schools). A total of 4603 students participated (mean [±SD] age, 11.3±0.6 years; 54.2% Hispanic and 18.0% black; 52.7% girls). At the beginning of 6th grade and the end of 8th grade, students underwent measurements of body-mass index (BMI), waist circumference, and fasting glucose and insulin levels. RESULTS There was a decrease in the primary outcome — the combined prevalence of overweight and obesity — in both the intervention and control schools, with no significant difference between the school groups. The intervention schools had greater reductions in the secondary outcomes of BMI z score, percentage of students with waist circumference at or above the 90th percentile, fasting insulin levels (P = 0.04 for all comparisons), and prevalence of obesity (P = 0.05). Similar findings were observed among students who were at or above the 85th percentile for BMI at baseline. Less than 3% of the students who were screened had an adverse event; the proportions were nearly equivalent in the intervention and control schools. CONCLUSIONS Our comprehensive school-based program did not result in greater decreases in the combined prevalence of overweight and obesity than those that occurred in control schools. However, the intervention did result in significantly greater reductions in various indexes of adiposity. These changes may reduce the risk of childhood-onset type 2 diabetes.

    The incidence of both type 1 and type 2 diabetes is increasing globally, most likely explained by environmental changes, such as changing exposures to foods, viruses, and toxins, and by increasing obesity. While cardiovascular disease (CVD) mortality has been declining recently, this global epidemic of diabetes threatens to stall this trend. CVD is the leading cause of death in both type 1 and type 2 diabetes, with at least a two- to fourfold increased risk in patients with diabetes. In this review, the risk factors for CVD are discussed in the context of type 1 and type 2 diabetes. While traditional risk factors such as dyslipidemia, hypertension, and obesity are greater in type 2 patients than in type 1 diabetes, they explain only about half of the increased CVD risk. The role for diabetes-specific risk factors, including hyperglycemia and kidney complications, is discussed in the context of new study findings. PMID:23519720

    Human parechoviruses (HPeVs) are RNA viruses associated mainly with mild gastrointestinal and respiratory infections in children and also cause neonatal sepsis and CNS infections. Human enteroviruses, close relatives of HPeVs, associate with the development of type 1 diabetes. In this study, the potential role of HPeV infections in promoting beta cell autoimmunity was investigated by analyzing stool samples of 54 prediabetic case and 134 healthy control children for the presence of HPeV RNA and comparing the derived infection frequencies. All 188 children were participants of the Finnish prospective Diabetes Prediction and Prevention study. Viral RNA was screened for using an HPeV-specific RT-PCR method coupled to liquid hybridization of the PCR product. The overall HPeV infection frequency did not differ between prediabetic case and control children. However, case boys had more HPeV positive samples in the 6-month period before becoming autoantibody positive, when compared to the matching time-period in controls (P < 0.01). HPeV infection at a young age does not appear to play a major role in the development of beta-cell autoimmunity. In boys, however, HPeVs showed time-dependent association with the first detection of diabetes-associated autoantibodies. Thus, in boys, HPeV infections cannot be excluded as a gender-specific risk factor which promotes the development of type 1 diabetes. PMID:23852688

    Distinguishing patients with monogenic diabetes from those with type 1 diabetes (T1D) is important for correct diagnosis, treatment, and selection of patients for gene discovery studies. We assessed whether a T1D genetic risk score (T1D-GRS) generated from T1D-associated common genetic variants provides a novel way to discriminate monogenic diabetes from T1D. The T1D-GRS was highly discriminative of proven maturity-onset diabetes of young (MODY) (n = 805) and T1D (n = 1,963) (receiver operating characteristic area under the curve 0.87). A T1D-GRS of >0.280 (>50th T1D centile) was indicative of T1D (94% specificity, 50% sensitivity). We then analyzed the T1D-GRS of 242 white European patients with neonatal diabetes (NDM) who had been tested for all known NDM genes. Monogenic NDM was confirmed in 90, 59, and 8% of patients with GRS <5th T1D centile, 50-75th T1D centile, and >75th T1D centile, respectively. Applying a GRS 50th T1D centile cutoff in 48 NDM patients with no known genetic cause identified those most likely to have a novel monogenic etiology by highlighting patients with probable early-onset T1D (GRS >50th T1D centile) who were diagnosed later and had less syndromic presentation but additional autoimmune features compared with those with proven monogenic NDM. The T1D-GRS is a novel tool to improve the use of biomarkers in the discrimination of monogenic diabetes from T1D. PMID:27207547

    AIM To investigate the prevalence and risk factors of diabetic retinopathy (DR) in northern Chinese patients with type 2 diabetes mellitus (T2DM). METHODS This retrospective cross-sectional study was performed between May 2011 and April 2012. A total of 1100 patients (male/female, 483/617) were included in this study. DR was defined following the Early Treatment Diabetic Retinopathy Study (ETDRS) severity scale. All included patients accepted a comprehensive ophthalmic examination including retinal photographs. Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence interval (CI) after adjusting for age and gender. RESULTS Retinopathy was present in 307 patients with a prevalence of 27.9%. In univariate logistic analysis, presence of DR was associated with longer duration of diabetes (OR, 5.70; 95%CI, 2.91-12.56), higher concentration of fasting blood glucose (OR, 12.94; 95%CI, 2.40-67.71), higher level of glycosylated hemoglobin HbA1c (OR, 5.50; 95%CI, 3.78-11.97) and insulin treatment (OR, 6.99; 95%CI, 1.39-35.12). The lifestyle of patients with T2DM including smoking, alcohol consumption and regular exercise seemed not associated with the development of DR. CONCLUSION Our study suggests that fasting serum glucose concentration, HbA1c level, duration of diabetes and insulin treatment are potential risk factors for DR in northern Chinese patients with T2DM, while the lifestyle of included patients seems not associated with DR.

    Research ethics committees (RECs) are tasked to assess the risks and the benefits of a clinical trial. In previous studies, it was shown that RECs find this task difficult, if not impossible, to do. The current approaches to benefit-risk assessment (i.e. Component Analysis and the Net Risk Test) confound the various risk-benefit tasks, and as such, make balancing impossible. In this article, we show that decision theory, specifically through the expected utility theory and multiattribute utility theory, enable for an explicit and ethically weighted risk-benefit evaluation. This makes a balanced ethical justification possible, and thus a more rationally defensible decision making. PMID:22819925

    Gestational diabetes mellitus (GDM) is the most common medical complication of pregnancy and is particularly prevalent among obese women. Both GDM and obesity confer significant comorbidities for the mother and her offspring, including perinatal complications, excessive fetal growth and long-term risks for maternal and offspring obesity and diabetes. Exercise has well-documented health benefits and reduces peripheral insulin resistance in nonpregnant individuals, a major risk factor for the development of diabetes. Observational studies conducted in large population-based cohorts suggest that women who are the most active before pregnancy are less insulin-resistant in late pregnancy and have lower rates of GDM. This article will review the evidence supporting a role for exercise in the prevention of GDM, the management of glycemic control in women with established GDM, and the reduction of GDM-associated maternal and offspring health consequences. Wherever possible, the discussion will focus on studies carried out on obese women. However, there are many areas where strong evidence is lacking in obese populations, and it may be inferred from similar studies performed in normal weight pregnant women. PMID:24161309

    Diabetic retinopathy affects 4.2 million people in the United States and is the leading cause of blindness in working-aged people. As the prevalence of diabetes continues to rise, cost-effective interventions to decrease blindness from diabetic retinopathy will be paramount. While HbA1c and duration of disease are known risk factors, they account for only 11% of the risk of developing microvascular complications from the disease. The assessment of environmental risk factors for diabetic eye disease allows for the determination of modifiable population-level challenges that may be addressed to facilitate the end of blindness from diabetes.

    This study aimed to determine how college students perceive their risk of developing diabetes over their life course, with specific emphasis on their beliefs about the influence of inherited versus behavioral risk factors. A bivariate ordered probit regression model was used to simultaneously predict perceived risk for 10-year absolute risk of diabetes and lifetime absolute risk of diabetes. Ten-year and lifetime absolute risk were both increased when the respondent self-identified with a race/ethnicity other than non-Hispanic white (β = 0.42, p < .001 and β = 0.33, p = .004, respectively), and when the respondent had an increasing number of family members with diabetes (β = 0.33, p < .001 and β = 0.45, p < .001, respectively). Beliefs linking behavioral risk factors to perceived risk of developing diabetes across the life course were not statistically significant. The absence of significant association between perceptions of behavioral risk as factors for developing diabetes and perceived risk for diabetes over the life course supports the need for educational interventions about behavioral and genetic causes of diabetes among the college-aged population.

  3. Communicating vaccine benefit and risk - lessons from the medical field.

    The childhood immunisation programme in England aims to achieve and maintain high vaccine coverage so that no child needlessly suffers from a vaccine preventable disease. As part of the programme, parents must have appropriate support from health professionals and have information available to them to make informed decisions about their choices. Even though immunisation is voluntary in England, coverage is generally high. It has been estimated that only 0.33% of parents do not consent to their child being included in a computerised database that schedules immunisation appointments. Parental attitudes, experiences and social grade are influential in determining whether a child receives a vaccine. Personal experience and knowledge of diseases influence parental perceptions about the seriousness of diseases and their likelihood of being affected by it. In societies where immunisation programmes have been successful, the challenge is maintaining high levels of vaccine coverage. In the absence of disease, the threat of that disease rapidly disappears and anxieties about the vaccine's safety may increase. A fall in vaccine coverage can lead to the return of disease as happened in the UK when rates of pertussis immunisation plummeted in the 1970s. Further perceived threats may also affect vaccine uptake, for example, the MMR controversy dating from 1998. The article outlines the MMR debate in the UK, the communication of risk and benefit and the management of information to the public. It will share lessons learned and examine how they might apply to the veterinary programme. PMID:16854535

    Kahnawake is a Mohawk community located on the south shore of the Saint Lawrence River near Montreal. A comprehensive study was conducted in 1996--1997 to address the local concern regarding health risks of contaminant exposure associated with freshwater fish consumption. Forty-two participants, including most of the identified active fishermen were interviewed. Walleye, perch, bullhead, and smallmouth bass were the species most consumed. Average daily intake of locally caught fish was 23 g/day. Nutrient and contaminant levels of locally collected fish were analyzed. Fish were good sources of protein, polyunsaturated fatty acids, calcium, zinc, and iron. Levels of cadmium, lead, arsenic, polychlorinated biphenyls (PCBs), and other chlorinated pesticides were at least 10 times lower than the guideline levels. Mercury levels of some predatory fish exceeded the guideline of 0.5 {micro}g/g. Average daily intakes of all contaminants were below the guideline levels by a factor of 10 except for mercury. Average mercury intake rate was about one-third that of the guideline level. Contrary to residents` perception, Kahnawake fish were not particularly contaminated. In view of the nutritional as well as cultural benefits, fishing and fish consumption may be promoted.

    In Mexico, local empirical knowledge about medicinal properties of plants is the basis for their use as home remedies. It is generally accepted by many people in Mexico and elsewhere in the world that beneficial medicinal effects can be obtained by ingesting plant products. In this review, we focus on the potential pharmacologic bases for herbal plant efficacy, but we also raise concerns about the safety of these agents, which have not been fully assessed. Although numerous randomized clinical trials of herbal medicines have been published and systematic reviews and meta-analyses of these studies are available, generalizations about the efficacy and safety of herbal medicines are clearly not possible. Recent publications have also highlighted the unintended consequences of herbal product use, including morbidity and mortality. It has been found that many phytochemicals have pharmacokinetic or pharmacodynamic interactions with drugs. The present review is limited to some herbal medicines that are native or cultivated in Mexico and that have significant use. We discuss the cultural uses, phytochemistry, pharmacological, and toxicological properties of the following plant species: nopal (Opuntia ficus), peppermint (Mentha piperita), chaparral (Larrea divaricata), dandlion (Taraxacum officinale), mullein (Verbascum densiflorum), chamomile (Matricaria recutita), nettle or stinging nettle (Urtica dioica), passionflower (Passiflora incarnata), linden flower (Tilia europea), and aloe (Aloe vera). We conclude that our knowledge of the therapeutic benefits and risks of some herbal medicines used in Mexico is still limited and efforts to elucidate them should be intensified. PMID:18037151

    Scientists employing methods of genetic engineering have developed a new group of living organisms, termed 'modified organisms', which found application in, among others, medicine, the pharmaceutical industry and food distribution. The introduction of transgenic products to the food market resulted in them becoming a controversial topic, with their proponents and contestants. The presented study aims to systematize objective data on the potential benefits and risks resulting from the consumption of transgenic food. Genetic modifications of plants and animals are justified by the potential for improvement of the food situation worldwide, an increase in yield crops, an increase in the nutritional value of food, and the development of pharmaceutical preparations of proven clinical significance. In the opinions of critics, however, transgenic food may unfavourably affect the health of consumers. Therefore, particular attention was devoted to the short- and long-lasting undesirable effects, such as alimentary allergies, synthesis of toxic agents or resistance to antibiotics. Examples arguing for the justified character of genetic modifications and cases proving that their use can be dangerous are innumerable. In view of the presented facts, however, complex studies are indispensable which, in a reliable way, evaluate effects linked to the consumption of food produced with the application of genetic engineering techniques. Whether one backs up or negates transgenic products, the choice between traditional and non-conventional food remains to be decided exclusively by the consumers. PMID:24069841

    Numerous epidemiological studies confirm that the prevalence of obesity and the cardiorenal metabolic syndrome (CRS) is extraordinarily high and that the rates have increased dramatically in the last three decades. In addition, epidemiological data demonstrate that obesity, the CRS, and diabetes are inextricably linked and are all associated with an increased incidence of a number of solid tissue cancers. The mechanisms for this association have been examined, including, but not limited to, higher levels of insulin and free levels of insulin-like growth factor and insulin resistance in obesity and the CRS. Mortality, morbidity, and the associated health care costs which are the link between obesity, the CRS, and diabetes are just beginning to be examined. In addition, we review the advantages of implementing lifestyle and surgical changes to modify obesity, lessening the development of the CRS, diabetes, and associated cancers. Epidemiological data regarding the general mechanisms of the pathogenesis of cancers associated with obesity, the CRS, and diabetes (specifically colon, pancreas, esophageal, liver, breast, prostate, thyroid, and renal carcinomas) are reviewed. The mechanisms by which obesity and other components of the CRS contribute to the pathogenesis of these cancers, such as hormone alterations and insulin- and insulin-like growth factor-dependent pathways of tumor pathogenesis, include the attending roles of inflammation and oxidative stress. Emphasis has been placed on obesity as a modifiable risk factor which, when addressed, provides a reduction in the rate of cancer deaths. In a second part to be published in the next issue of this journal, the relationship between diabetes and cancer will be reviewed in detail. PMID:22851963

    HIV infection and its treatment have been associated with adipose tissue changes and disorders of glucose and lipid metabolism. The proportion of HIV-infected adults over the age of 50 is also growing placing HIV-infected adults at particular risk for metabolic perturbations and cardiovascular disease. The metabolic syndrome in HIV-infected adults has been increasingly studied but whether HIV is associated with greater risk remains unclear, likely because of the interplay of host, viral and antiretroviral factors that are associated with the components of the metabolic syndrome. While the Framingham Risk Score is a well-accepted measure of 10-year cardiovascular risk in the general population, it may not accurately predict risk in the HIV setting due to HIV-related factors such as inflammation that are not accounted for. The relationship between HIV and diabetes mellitus (DM) risk has also been debated. We summarize the recent literature on metabolic syndrome, DM, and cardiovascular risk in HIV-infected adults.

    All market participants (e.g., investors, producers, consumers) accept a certain level of risk as necessary to achieve certain benefits. There are many types of risk including price, production, financial, institutional, and individual human risks. All these risks should be effectively managed in order to derive the utmost of benefits and avoid disruption and/or catastrophic economic consequences for the food industry. The identification, analysis, determination, and understanding of the benefit-risk trade-offs of market participants in the food markets may help policy makers, financial analysts and marketers to make well-informed and effective corporate investment strategies in order to deal with highly uncertain and risky situations. In this paper, we discuss the role that benefits and risks play in the formation of the decision-making process of market-participants, who are engaged in the upstream and downstream stages of the food supply chain. In addition, we review the most common approaches (expected utility model and psychometrics) for measuring benefit-risk trade-offs in the economics and marketing-finance literature, and different factors that may affect the economic behaviour in the light of benefit-risk analyses. Building on the findings of our review, we introduce a conceptual framework to study the benefit-risk behaviour of market participants. Specifically, we suggest the decoupling of benefits and risks into the separate components of utilitarian benefits, hedonic benefits, and risk attitude and risk perception, respectively. Predicting and explaining how market participants in the food industry form their overall attitude in light of benefit-risk trade-offs may be critical for policy-makers and managers who need to understand the drivers of the economic behaviour of market participants with respect to production, marketing and consumption of food products.

    Knowledge about differences in consumer perceptions of health risks and benefits related to fish consumption is important for the development of targeted health interventions associated with dietary choice. The purpose of this study is to identify individual differences in Russian consumers according to their perceptions of health risks and benefits associated with fish consumption. By application of a cluster analysis on perceptions of personal risks and benefits associated with the consumption of fish, four groups of Russian consumers were classified as: very positive; positive; moderately positive; and 'high risk-high benefit' about the healthiness of fish consumption. Differences in perceptions of personal risks and benefits across consumers were related to self-reported fish consumption, optimism about personal risks and benefits, and optimism about personal knowledge about risks and benefits. Implications for the development of targeted health interventions to influence perceptions of risks and benefits associated with fish consumption, and ultimately fish consumption, are discussed. It is concluded that optimism regarding perceptions and knowledge of health risks, and health benefits should be taken into account when developing interventions aimed at consumer health.

    The number of people suffering from metabolic disorders is dramatically increasing worldwide. The need for new therapeutic strategies to combat this growing epidemic of metabolic diseases is therefore also increasing. In 2003, resveratrol was discovered to be a small molecule activator of sirtuin 1 (SIRT1), an important molecular target regulating cellular energy metabolism and mitochondrial homeostasis. Rodent studies have clearly demonstrated the potential of resveratrol to improve various metabolic health parameters. To date, however, only limited clinical data are available that have systematically examined the health benefits of resveratrol in metabolically challenged humans. This short review will give an overview of the currently available clinical studies examining the effects of resveratrol on obesity and type 2 diabetes from a human perspective. PMID:23855469

    2013-01-01

    Late-onset hypogonadism (LOH) is a syndromic condition that has a well-recognized association with sexual and reproductive failure. LOH is frequently associated with chronic conditions including cardiovascular diseases (CVD), obesity, osteoporosis, HIV infection, renal failure, and obstructive pulmonary diseases. Despite this evidence, in patients with these conditions, LOH is still only rarely investigated and testosterone replacement therapy (TRT) rarely considered. In this paper, we critically reviewed the available evidence on LOH treatment focusing on possible risks and benefits. Medical therapy of LOH should be individualized depending on the etiology of the disease and the patient's expectations. The fear of prostate cancer and the risk of erythrocytosis probably represent the main limitations of TRT in aging men. However, TRT in healthy older men in near physiological doses does not appear to incur serious adverse events, although regular monitoring of prostate-specific antigen and hematocrit levels is required. Available evidence also suggests that TRT might ameliorate central obesity and glycometabolic control in patients with metabolic syndrome and type 2 diabetes. In addition, TRT has been associated with an increase in bone mineral density in men with osteoporosis, with an improvement in lean body mass in subjects with human immunodeficiency virus infection or chronic obstructive pulmonary disease, as well as with peripheral oxygenation in patients with chronic kidney diseases. Despite this evidence, however, it should be recognized that the results of these trials were heterogeneous and limited by small sample sizes. Hence, further research is required regarding the long-term benefits and adverse effects of TRT in LOH. PMID:24044106

    The field of nanotechnology is developing rapidly, as are its practical application in society. In this article, we give examples that demonstrate the enormous potential that exists for this new class of materials, and for devices with critical dimensions of less than 100 nm. We also identify some of the challenges that need to be faced in order to fully realize the practical benefits of nanotechnology, and discuss possible risks that may come with this new technology. In all cases, the unique advantage of nanotechnology can be traced back to nanoscale physical and chemical properties that are quite different from those encountered in more traditional microscopic (micro) or macroscopic (macro) materials and devices. Unique nanoscale properties and behaviors are already being used to increase energy efficiency, improve healthcare, and strengthen national security. However, while progress is rapid, many challenges remain. These include manufacturing at the nanoscale, integration of nanoscale materials and devices with more conventional technology, and predictive modeling that will allow nanotechnology to be engineered reliably into useful applications and products. Nanotechnology can be expected to have an increasing impact on human lives and society at large. As we strive to use nanotechnology to improve human life through better healthcare, cleaner environment, and improved national security, we must also work to detect and assess the negative impacts that nanotechnology science (or any new technology) might bring. We suggest that the conduct of should be allowed to proceed unimpeded, so that we can fully understand and appreciate the rules of nature at the nanometer scale. That said, scientific pursuits that involve self-replication in synthetic systems, encryption, defense technology, or the enhancement of human intelligence should be reviewed.

    2014-03-01

    In the face of a growing public health concern accompanying the reemerging threat of preventable diseases, this research seeks mainly to explain variations in the perceived benefits and risks of vaccinations among the general public in the United States. As Mary Douglas and Aaron Wildavsky's grid-group cultural theory of risk perception claims, the analytical results based upon original data from a nationwide Internet survey of 1,213 American adults conducted in 2010 suggest that individuals' cultural predispositions contribute to the formation of their perceptions pertaining to vaccine benefits and risks at both societal and individual levels, in conjunction with other factors suggested by previous risk perception literature, such as perceived prevalence of diseases, trust, knowledge level, and demographic characteristics. Those with a strong hierarch orientation tend to envision greater benefits and lesser risks and conceive of a relatively high ratio of benefit to risk when compared to other cultural types. By contrast, those with a strong fatalist tendency are inclined to emphasize risks and downplay benefits while conceiving of a low vaccination benefit-risk ratio. Situated between hierarchs and fatalists, strong egalitarians are prone to perceive greater benefits, smaller risks, and a more positive benefit-risk ratio than strong individualists. PMID:24033739

    Benefit and risk perception with respect to food consumption, have been a part of human daily life from beginning of time. In today's society the food chain is long with many different types of actors and low degree of transparency. Making informed food choices where knowledge of benefits and risks is part of the decision making process are therefore complicated for consumers. Thus, to understand how consumers perceive benefits and risks of foods, their importance in relation to quality evaluations are aspects that need to be addressed. The objective of this paper is to discuss state of the art in understanding consumer perceptions of benefits and risks of foods in order to improve understanding of consumer behaviour in the food domain. Risks may be associated with both acute and long term consequences, some of which may have serious effects. Perceived risks are connected to morbidity and mortality along two dimensions relating to unknown risk, and to which extent the risk is dreaded by the consumer. Unfamiliar, uncertain, unknown, uncontrollable, and severe consequences are some factors associated with risk perception. Novel food processing techniques, for instance, score high on several of these parameters and are consequently regarded with suspicion and perceived as risky by consumers. On a daily basis, benefits of foods and food consumption are more important in most consumers' minds than risks. Benefits are often associated with food's ability to assuage hunger, and to provide pleasure through eating and socialising. In addition, two main categories of benefits that are important for acceptance of product innovations are health and environmental benefits. Benefit and risk perception of foods seem to be inversely correlated, so when something is perceived as being highly beneficial, it is correspondingly perceived as having low risk. However, slightly different paths are used in the formation of these perceptions; benefit perception is based on heuristics and

    Several limitations existed in previous studies which suggested that diabetic patients have increased risk of stroke. We conducted this study to better understand the stroke risk and poststroke outcomes in patients with diabetes.From the claims data of Taiwan's National Health Insurance, we identified 24,027 adults with new-diagnosed diabetes and 96,108 adults without diabetes between 2000 and 2003 in a retrospective cohort study. Stroke events (included hemorrhage, ischemia, and other type of stroke) during the follow-up period of 2000 to 2008 were ascertained and adjusted risk of stroke associated with diabetes was calculated. A nested cohort study of 221,254 hospitalized stroke patients (included hemorrhage, ischemia, and other type of stroke) between 2000 and 2009 was conducted. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for adverse events after stroke hospitalization in patients with and without diabetes.The incidences of stroke in cohorts with and without diabetes were 10.1 and 4.5 per 1000 person-years, respectively. During the follow-up period, diabetic patients had an increased risk of stroke (adjusted hazard ratio: 1.75; 95% CI: 1.64-1.86) than those without diabetes. Associations between diabetes and stroke risk were significant in both sexes and all age groups. Previous diabetes was associated with poststroke mortality (OR: 1.33; 95% CI: 1.19-1.49), pneumonia (OR: 1.30; 95% CI: 1.20-1.42), and urinary tract infection (OR: 1.66; 95% CI: 1.55-1.77). The impact of diabetes on adverse events after stroke was investigated particularly in those with diabetes-related complications.Diabetes was associated with stroke risk, and diabetic patients had more adverse events and subsequent mortality after stroke.

    Background To determine rates of diabetes, hypertension, and hyperlipidemia in Cambodian refugees, and to assess the proportion whose conditions are satisfactorily managed in comparison to the general population. Methods Self-report and laboratory/physical health assessment data obtained from a household probability sample of U.S.-residing Cambodian refugees (N = 331) in 2010-2011 were compared to a probability sample of the adult U.S. population (N = 6360) from the 2009-2010 National Health and Nutrition Examination Survey. Results Prevalence of diabetes, hypertension and hyperlipidemia in Cambodian refugees greatly exceeded rates found in the age- and gender-adjusted U.S. population. Cambodian refugees with diagnosed hypertension or hyperlipidemia were less likely than their counterparts in the general U.S. population to have blood pressure and total cholesterol within recommended levels. Conclusions Increased attention should be paid to prevention and management of diabetes and cardiovascular disease risk factors in the Cambodian refugee community. Research is needed to determine whether this pattern extends to other refugee groups. PMID:25651882

    Objective Depression is increasingly recognized as a risk factor for type 2 diabetes, and is also commonly comorbid with anxiety. However, few studies have examined whether anxiety is predictive of diabetes risk. The objectives of this study are to examine the prospective relationship between anxiety disorders (generalized anxiety disorder, panic disorder, social phobia, and agoraphobia) and risk of type 2 diabetes over an 11-year period, and to investigate the association between anxiety and risk of diabetes-related complications among those with prevalent type 2 diabetes. Methods Data come from the 1993/6 and 2004/5 waves of the Baltimore Epidemiologic Catchment Area Study (N=1920), a population-based prospective cohort. Anxiety disorders were assessed using the Diagnostic Interview Schedule. The prospective association between anxiety and incident type 2 diabetes was evaluated using a series of nested multivariable logistic regression models. Results At baseline, 315 participants (21.8%) had an anxiety disorder. The relationship between anxiety and risk of developing type 2 diabetes was not statistically significant after controlling for demographic characteristics (Odds Ratio (OR): 1.28, 95% Confidence Interval (CI): 0.75, 2.18). There was no relationship between anxiety and diabetes risk after controlling for health behaviors and depression status (OR: 1.00, 95% CI: 0.53, 1.89). There was no significant relationship between anxiety and development of diabetes-related complications among those with prevalent type 2 diabetes (OR: 2.02, 95% CI: 0.61, 6.74). Conclusion Anxiety disorders are not associated with increased risk of type 2 diabetes or risk of diabetes complications among those who have diabetes in the present study. PMID:23148808

    An estimated 72.5 million American adults are obese, and the growing US obesity epidemic is responsible for substantial increase in morbidity and mortality, as well as increased health care costs. Obesity results from a combination of personal and societal factors, but is often viewed as a character flaw rather than a medical condition. This leads to stigma and discrimination towards obese individuals and decreases the likelihood of effective intervention. Conditions related to obesity are increasingly common, such as metabolic syndrome, impaired fasting glucose (IFG) and impaired glucose tolerance (IGT), all of which indicate high risk for type 2 diabetes (T2DM). This paper reviews the progression from obesity to diabetes, identifying physiological changes that occur along this path as well as opportunities for patient identification and disease prevention. Patients with prediabetes (defined as having IFG, IGT or both) and/or metabolic syndrome require interventions designed to preserve insulin sensitivity and β-cell function, both of which start to deteriorate prior to T2DM diagnosis. Lifestyle modification, including both healthy eating choices and increased physical activity, is essential for weight management and diabetes prevention. Although sustained weight loss is often considered by patients and physicians as being impossible to achieve, effective interventions do exist. Specifically, the Diabetes Prevention Program (DPP) and programs modelled along its parameters have shown repeated successes, even with long-term maintenance. Recent setbacks in the development of medications for weight loss further stress the importance of lifestyle management. By viewing obesity as a metabolic disorder rather than a personal weakness, we can work with patients to address this increasingly prevalent condition and improve long-term health outcomes.

    A strong link between obesity, insulin resistance, and metabolic syndrome has been reported with development of a new paradigm to type 2 diabetes mellitus (T2DM), with some evidence suggesting that beta-cell dysfunction is present before the onset of impaired glucose tolerance. Differentiating type 1 diabetes mellitus (T1DM) from T2DM is actually not very easy and there exists a number of overlapping characteristics. The autoantibody frequencies of seven antigens in T1DM patients may turn out to be actually having T2DM patients (pre-T2DM). T2DM patients generally have increased C-peptide levels (may be normal at time of diagnosis), usually no auto-antibodies, strong family history of diabetes, obese and show signs of insulin resistance (hypertension, acanthosis, PCOS). The American Academy of Paediatrics recommends lifestyle modifications ± metformin when blood glucose is 126–200 mg/dL and hemoglobin A1c (HbA1c) <8.5. Insulin is recommended when blood glucose is >200 mg/dL and HbA1c >8.5, with or without ketosis. Metformin is not recommended if the patient is ketotic, because this increases the risk of lactic acidosis. Metformin is currently the only oral hypoglycemic that has been approved for use in children. Knowing these subtle differences in mechanism, and knowing how to test patients for which mechanism (s) are causing their diabetes mellitus, may help us eventually tailor treatment programs on an individual basis.

    Obesity and type 2 diabetes are becoming increasingly prevalent worldwide, and both are associated with an increased incidence and mortality from many cancers. The metabolic abnormalities associated with type 2 diabetes develop many years before the onset of diabetes and, therefore, may be contributing to cancer risk before individuals are aware that they are at risk. Multiple factors potentially contribute to the progression of cancer in obesity and type 2 diabetes, including hyperinsulinemia and insulin-like growth factor I, hyperglycemia, dyslipidemia, adipokines and cytokines, and the gut microbiome. These metabolic changes may contribute directly or indirectly to cancer progression. Intentional weight loss may protect against cancer development, and therapies for diabetes may prove to be effective adjuvant agents in reducing cancer progression. In this review we discuss the current epidemiology, basic science, and clinical data that link obesity, diabetes, and cancer and how treating obesity and type 2 diabetes could also reduce cancer risk and improve outcomes.

    Diets that boost ketone production are increasingly used for treating several neurological disorders. Elevation in ketones in most cases is considered favorable, as they provide energy and are efficient in fueling the body's energy needs. Despite all the benefits from ketones, the above normal elevation in the concentration of ketones in the circulation tend to illicit various pathological complications by activating injurious pathways leading to cellular damage. Recent literature demonstrates a plausible link between elevated levels of circulating ketones and oxidative stress, linking hyperketonemia to innumerable morbid conditions. Ketone bodies are produced by the oxidation of fatty acids in the liver as a source of alternative energy that generally occurs in glucose limiting conditions. Regulation of ketogenesis and ketolysis plays an important role in dictating ketone concentrations in the blood. Hyperketonemia is a condition with elevated blood levels of acetoacetate, 3-β-hydroxybutyrate, and acetone. Several physiological and pathological triggers, such as fasting, ketogenic diet, and diabetes cause an accumulation and elevation of circulating ketones. Complications of the brain, kidney, liver, and microvasculature were found to be elevated in diabetic patients who had elevated ketones compared to those diabetics with normal ketone levels. This review summarizes the mechanisms by which hyperketonemia and ketoacidosis cause an increase in redox imbalance and thereby increase the risk of morbidity and mortality in patients.

    Background While current recommendations on exercise type and volume have strong experimental bases, there is no clear evidence from large-sized studies indicating whether increasing training intensity provides additional benefits to subjects with type 2 diabetes. Objective To compare the effects of moderate-to-high intensity (HI) versus low-to-moderate intensity (LI) training of equal energy cost, i.e. exercise volume, on modifiable cardiovascular risk factors. Design Pre-specified sub-analysis of the Italian Diabetes and Exercise Study (IDES), a randomized multicenter prospective trial comparing a supervised exercise intervention with standard care for 12 months (2005–2006). Setting Twenty-two outpatient diabetes clinics across Italy. Patients Sedentary patients with type 2 diabetes assigned to twice-a-week supervised progressive aerobic and resistance training plus exercise counseling (n = 303). Interventions Subjects were randomized by center to LI (n = 142, 136 completed) or HI (n = 161, 152 completed) progressive aerobic and resistance training, i.e. at 55% or 70% of predicted maximal oxygen consumption and at 60% or 80% of predicted 1-Repetition Maximum, respectively, of equal volume. Main Outcome Measure(s) Hemoglobin (Hb) A1c and other cardiovascular risk factors; 10-year coronary heart disease (CHD) risk scores. Results Volume of physical activity, both supervised and non-supervised, was similar in LI and HI participants. Compared with LI training, HI training produced only clinically marginal, though statistically significant, improvements in HbA1c (mean difference −0.17% [95% confidence interval −0.44,0.10], P = 0.03), triglycerides (−0.12 mmol/l [−0.34,0.10], P = 0.02) and total cholesterol (−0.24 mmol/l [−0.46, −0.01], P = 0.04), but not in other risk factors and CHD risk scores. However, intensity was not an independent predictor of reduction of any of these parameters. Adverse event rate was similar in HI and

    Benefit-risk assessment in food and nutrition is relatively new. It weighs the beneficial and adverse effects that a food (component) may have, in order to facilitate more informed management decisions regarding public health issues. It is rooted in the recognition that good food and nutrition can improve health and that some risk may be acceptable if benefit is expected to outweigh it. This paper presents an overview of current concepts and practices in benefit-risk analysis for food and nutrition. It aims to facilitate scientists and policy makers in performing, interpreting and evaluating benefit-risk assessments. Historically, the assessments of risks and benefits have been separate processes. Risk assessment is mainly addressed by toxicology, as demanded by regulation. It traditionally assumes that a maximum safe dose can be determined from experimental studies (usually in animals) and that applying appropriate uncertainty factors then defines the 'safe' intake for human populations. There is a minor role for other research traditions in risk assessment, such as epidemiology, which quantifies associations between determinants and health effects in humans. These effects can be both adverse and beneficial. Benefit assessment is newly developing in regulatory terms, but has been the subject of research for a long time within nutrition and epidemiology. The exact scope is yet to be defined. Reductions in risk can be termed benefits, but also states rising above 'the average health' are explored as benefits. In nutrition, current interest is in 'optimal' intake; from a population perspective, but also from a more individualised perspective. In current approaches to combine benefit and risk assessment, benefit assessment mirrors the traditional risk assessment paradigm of hazard identification, hazard characterization, exposure assessment and risk characterization. Benefit-risk comparison can be qualitative and quantitative. In a quantitative comparison, benefits

    Purpose: This study examined the associations between participant and site characteristics and retention in a multisite cardiovascular disease risk reduction project. Design and Methods: Data were derived from the Special Diabetes Program for Indians Healthy Heart Demonstration Project, an intervention to reduce cardiovascular risk among American Indians and Alaska Natives with diabetes. In 2006, a total of 1,072 participants from 30 participating sites completed baseline questionnaires measuring demographics and sociobehavioral factors. They also underwent a medical examination at baseline and were reassessed annually after baseline. A Provider Annual Questionnaire was administered to staff members of each grantee site at the end of each year to assess site characteristics. Generalized estimating equation models were used to evaluate the relationships between participant and site characteristics and retention 1 year after baseline. Results: Among enrolled participants, 792 (74%) completed their first annual assessment. Participants who completed the first annual assessment tended to be older and had, at baseline, higher body mass index and higher level of physical activity. Site characteristics associated with retention included average age of staff, proportion of female staff members, and percentage of staff members having completed graduate or professional school. Implications: Understanding successful retention must reach beyond individual characteristics of participants to include features of the settings that house the interventions.

    A systematic review relevant to the following research questions was conducted (1) the extent to which different theoretical frameworks have been applied to food risk/benefit communication and (2) the impact such food risk/benefit communication interventions have had on related risk/benefit attitudes and behaviors. Fifty four papers were identified. The analysis revealed that (primarily European or US) research interest has been relatively recent. Certain food issues were of greater interest to researchers than others, perhaps reflecting the occurrence of a crisis, or policy concern. Three broad themes relevant to the development of best practice in risk (benefit) communication were identified: the characteristics of the target population; the contents of the information; and the characteristics of the information sources. Within these themes, independent and dependent variables differed considerably. Overall, acute risk (benefit) communication will require advances in communication process whereas chronic communication needs to identify audience requirements. Both citizen's risk/benefit perceptions and (if relevant) related behaviors need to be taken into account, and recommendations for behavioral change need to be concrete and actionable. The application of theoretical frameworks to the study of risk (benefit) communication was infrequent, and developing predictive models of effective risk (benefit) communication may be contingent on improved theoretical perspectives.

    Purpose: The importance of a framework for a systematic structured assessment of the benefits and risks has been established, but in addition, it is necessary that the benefit-risk decisions and the processes to derive those decisions are documented and communicated to various stakeholders for accountability. Hence there is now a need to find appropriate tools to enhance communication between regulators and other stakeholders, in a manner that would uphold transparency, consistency and standards. Methods: A retrospective, non-comparative study was conducted to determine the applicability and practicality of a summary template in documenting benefit-risk assessment and communicating benefit-risk balance and conclusions for reviewers to other stakeholders. The benefit-risk (BR) Summary Template and its User Manual was evaluated by 12 reviewers within a regulatory agency in Singapore, the Health Sciences Authority (HSA). Results: The BR Summary Template was found to be adequate in documenting benefits, risks, relevant summaries and conclusions, while the User Manual was useful in guiding the reviewer in completing the template. The BR Summary Template was also considered a useful tool for communicating benefit-risk decisions to a variety of stakeholders. Conclusions: The use of a template may be of value for the communicating benefit-risk assessment of medicines to stakeholders. PMID:26124720

    Aims To determine the association of metabolic syndrome (MetS) and its components with diabetes risk in participants with impaired glucose tolerance (IGT), and whether intervention-related changes in MetS lead to differences in diabetes incidence. Methods We used the NCEP/ATP III revised MetS definition at baseline and intervention-related changes of its components to predict incident diabetes using Cox models in 3234 Diabetes Prevention Program (DPP) participants with IGT over an average follow-up of 3.2 years. Results In an intention-to-treat analysis, the demographic-adjusted hazard ratios (95%CI) for diabetes in those with MetS (versus no MetS) at baseline were 1.7(1.3-2.3), 1.7(1.2-2.3), and 2.0(1.3-3.0) for placebo, metformin, and lifestyle groups, respectively. Higher levels of fasting plasma glucose and triglycerides at baseline were independently associated with increased risk of diabetes. Greater waist circumference (WC) was associated with higher risk in placebo and lifestyle groups, but not in the metformin group. In a multivariate model, favorable changes in WC (placebo and lifestyle) and HDLc (placebo and metformin) contributed to reduced diabetes risk. Conclusions MetS and some of its components are associated with increased diabetes incidence in persons with IGT in a manner that differed according to DPP intervention. After hyperglycemia, the most predictive factors for diabetes were baseline hypertriglyceridemia and both baseline and lifestyle-associated changes in waist circumference. Targeting these cardio-metabolic risk factors may help to assess the benefits of interventions that reduce diabetes incidence. PMID:24118860

    Background The association between time spent walking and risk of diabetes was investigated in a Japanese population-based cohort. Methods Data from the Japan Public Health Center-based Prospective Diabetes cohort were analyzed. The surveys of diabetes were performed at baseline and at the 5-year follow-up. Time spent walking per day was assessed using a self-reported questionnaire (<30 minutes, 30 minutes to <1 hour, 1 to <2 hours, or ≥2 hours). A cross-sectional analysis was performed among 26 488 adults in the baseline survey. Logistic regression was used to examine the association between time spent walking and the presence of unrecognized diabetes. We then performed a longitudinal analysis that was restricted to 11 101 non-diabetic adults who participated in both the baseline and 5-year surveys. The association between time spent walking and the incidence of diabetes during the 5 years was examined. Results In the cross-sectional analysis, 1058 participants had unrecognized diabetes. Those with time spent walking of <30 minutes per day had increased odds of having diabetes in relation to those with time spent walking of ≥2 hours (adjusted odds ratio [OR] 1.23; 95% CI, 1.02–1.48). In the longitudinal analysis, 612 participants developed diabetes during the 5 years of follow-up. However, a significant association between time spent walking and the incidence of diabetes was not observed. Conclusions Increased risk of diabetes was implied in those with time spent walking of <30 minutes per day, although the longitudinal analysis failed to show a significant result. PMID:26725285

    Dietary fiber (DF) is deemed to be a key component in healthy eating. DF is not a static collection of undigestible plant materials that pass untouched or unencumbered through the gastrointestinal (GI) tract; instead, DFs are a vast array of complex saccharide-based molecules that can bind potential nutrients and nutrient precursors to prevent their absorption. Some DFs are fermentable, and the GI tract catabolism leads to the generation of various bioactive materials, such as short-chain fatty acids (SCFAs), that can markedly augment the GI tract biomass and change the composition of the GI tract flora. The health benefits of DFs include the prevention and mitigation of type 2 diabetes mellitus, cardiovascular disease and colon cancer. By modulating food ingestion, digestion, absorption and metabolism, DFs reduce the risk of hyperlipidemia, hypercholesterolemia and hyperglycemia. Emerging research has begun to investigate the role of DFs in immunomodulation. If substantiated, DFs could facilitate many biologic processes, including infection prevention and the improvement of mood and memory. This review describes the accepted physiologic functions of DFs and explores their new potential immune-based actions. PMID:22401879

    Diabetes mellitus is a chronic condition that occurs when the body cannot produce enough or effectively use of insulin. Compared with individuals without diabetes, patients with type 2 diabetes mellitus have a considerably higher risk of cardiovascular morbidity and mortality, and are disproportionately affected by cardiovascular disease. Most of this excess risk is it associated with an augmented prevalence of well-known risk factors such as hypertension, dyslipidaemia and obesity in these patients. However the improved cardiovascular disease in type 2 diabetes mellitus patients can not be attributed solely to the higher prevalence of traditional risk factors. Therefore other non-traditional risk factors may be important in people with type 2 diabetes mellitus. Cardiovascular disease is increased in type 2 diabetes mellitus subjects due to a complex combination of various traditional and non-traditional risk factors that have an important role to play in the beginning and the evolution of atherosclerosis over its long natural history from endothelial function to clinical events. Many of these risk factors could be common history for both diabetes mellitus and cardiovascular disease, reinforcing the postulate that both disorders come independently from “common soil”. The objective of this review is to highlight the weight of traditional and non-traditional risk factors for cardiovascular disease in the setting of type 2 diabetes mellitus and discuss their position in the pathogenesis of the excess cardiovascular disease mortality and morbidity in these patients.

    2011-01-01

    Background Given the increasing worldwide incidence of diabetes, methods to assess diabetes risk which would identify those at highest risk are needed. We compared two risk-stratification approaches for incident type 2 diabetes mellitus (T2DM); factors of metabolic syndrome (MetS) and a previously developed diabetes risk score, PreDx® Diabetes Risk Score (DRS). DRS assesses 5 yr risk of incident T2DM based on the measurement of 7 biomarkers in fasting blood. Methodology/Principal Findings DRS was evaluated in baseline serum samples from 4,128 non-diabetic subjects in the Inter99 cohort (Danes aged 30–60) for whom diabetes outcomes at 5 years were known. Subjects were classified as having MetS based on the presence of at least 3 MetS risk factors in baseline clinical data. The sensitivity and false positive rate for predicting diabetes using MetS was compared to DRS. When the sensitivity was fixed to match MetS, DRS had a significantly lower false positive rate. Similarly, when the false positive rate was fixed to match MetS, DRS had a significantly higher specificity. In further analyses, subjects were classified by presence of 0–2, 3 or 4–5 risk factors with matching proportions of subjects distributed among three DRS groups. Comparison between the two risk stratification schemes, MetS risk factors and DRS, were evaluated using Net Reclassification Improvement (NRI). Comparing risk stratification by DRS to MetS factors in the total population, the NRI was 0.146 (p = 0.008) demonstrating DRS provides significantly improved stratification. Additionally, the relative risk of T2DM differed by 15 fold between the low and high DRS risk groups, but only 8-fold between the low and high risk MetS groups. Conclusions/Significance DRS provides a more accurate assessment of risk for diabetes than MetS. This improved performance may allow clinicians to focus preventive strategies on those most in need of urgent intervention. PMID:21829540

    The prevalence of diabetes is on the increase in developed countries. Accordingly, the prevention and treatment of vision-threatening diabetic eye complications is assuming greater importance. The overall aim of this thesis is to analyse risk factors for intraocular surgery in a large diabetes population and to report surgical results. The specific objectives are to (1) estimate the incidence of diabetic vitrectomy and analyse risk factors (Study I), (2) report long-term results, prognostic factors and incidence of cataract surgery after diabetic vitrectomy (Study II), (3) report results and prognostic factors after cataract surgery in diabetes patients (Study III) and (4) analyse risk factors for diabetic papillopathy with emphasis on metabolic control variability (Study IV). All studies are based on a close-to-complete national surgery register and a large, closely followed diabetic retinopathy screening population. Study I (cohort study, 3980 type 1 diabetes patients) illustrates that diabetic vitrectomy is rarely required in a diabetes patient population with varying degrees of diabetic retinopathy. The risk of reaching diabetic vitrectomy increases fourfold with poor metabolic control, defined as glycosylated haemoglobin A1c > 75 mmol/mol (~9%), which points to good metabolic control as an important preventive measure. Study II (cohort study, 167 diabetes patients) shows that most diabetic vitrectomy patients stand to gain visual acuity ≥0.3 after surgery. Visual acuity is stable after 1 year, and the stability is maintained through 10 years of follow-up. The use of silicone oil for endotamponade is a consistent long-term predictor of low vision after surgery. The risk of requiring cataract surgery after diabetic vitrectomy is substantial, and the risk increases if silicone oil is used. Study III (cohort study, 285 diabetes patients) shows, on the other hand, that diabetes patients can expect a significant improvement in visual acuity after cataract

  4. Quantitative Risk-Benefit Analysis of Probiotic Use for Irritable Bowel Syndrome and Inflammatory Bowel Disease.

    Probiotics have seen widespread use for a variety of gastrointestinal problems, especially in two common disorders: irritable bowel syndrome and inflammatory bowel disease. Since a wide variety of probiotic preparations has been used, and despite a large number of studies performed, a great deal of heterogeneity exists among them. Straightforward evidence-based recommendations for the use of probiotics in irritable bowel syndrome and inflammatory bowel disease have thus been difficult to formulate. In an effort to improve understanding of the risk-benefit balance of probiotics in these conditions, this study (1) queried the US FDA Adverse Event Reporting System (FAERS) database for all reported adverse drug events related to probiotics in 2013, and (2) constructed risk-benefit planes for both irritable bowel syndrome and inflammatory bowel disease using a geometric approximation of the confidence region between risk and benefit. The results show that adverse events from probiotics vary widely by disease, and when they occur, they are mild and may be difficult to distinguish from the natural history of the underlying disorders they are used to treat. The risk-benefit plane for irritable bowel syndrome straddles the risk-benefit threshold, so patients can expect a balance between a low chance of risk and also a low chance of benefit. The risk-benefit plane for inflammatory bowel disease largely lies above the risk-benefit threshold, so patients may expect more benefit than risk in most cases. More standardized and high-quality research is needed to improve our understanding of risk and benefit for these complex biopharmaceuticals. PMID:26467550

    Purpose The purpose of this qualitative study was to understand how acculturation influences diabetes risk among urban, immigrant Latinas (Hispanic women). Methods Five focus groups were conducted with 26 urban, immigrant Latinas who were at high clinical risk for developing diabetes. The focus group sessions were audiotaped and transcribed verbatim. The authors independently analyzed transcripts using an inductive method of open coding, and themes were established by consensus among authors. Results All of the participants were foreign-born and had low levels of acculturation. During the acculturation process, they noted changes in their lifestyle behaviors and the family context in which those behaviors are shaped. They reported that since living in the U.S., their improved economic circumstances led to increased consumption of less healthy foods and beverages and a more sedentary lifestyle. They also described changing family roles and responsibilities, including working outside the home, which constrained healthy food choices. However, they perceived that their position of influence within the family offered opportunities to help family members prevent diabetes. Conclusions Lifestyle interventions to prevent diabetes in Latinas should address their acculturation experiences, which impact family functioning and health behaviors related to diabetes risk. For example, given the perceived link between Latinas’ improved economic circumstances and their diabetes risk, prevention programs should incorporate strategies to help Latinas avoid adopting less healthy lifestyle behaviors that become affordable during the acculturation process.

    Gestational diabetes mellitus (GDM), a common pregnancy complication, continues to be a significant public health and clinical problem. It carries significant short-term and long-term adverse health outcomes for both mother and offspring, which reinforces the significance of understanding risk factors, in particular modifiable factors, for GDM and of preventing the condition. Research in the past decade from observational studies has identified a few diet and lifestyle factors that are associated with GDM risk and demonstrated that time frames both before and during pregnancy may be relevant to the development of GDM. Findings from intervention studies on the effect of diet and lifestyle on the prevention of GDM have been largely controversial and inconsistent. Variations in study population, types of intervention, timing and duration of intervention and diagnostic criteria for GDM may all at least partly account for the large heterogeneity in the findings from these intervention studies. This review provides an overview of emerging diet, lifestyle, and other factors that may help to prevent GDM, and the challenges associated with prevention. It also discusses major methodological concerns about the available epidemiological studies on GDM risk factors. Findings from both observational and intervention studies are discussed. This review summarises a presentation given at the 'Gestational diabetes: what's up?' symposium at the 2015 annual meeting of the EASD. It is accompanied by two other reviews on topics from this symposium (by Peter Damm and Colleagues, DOI: 10.1007/s00125-016-3985-5 , and by Marja Vääräsmäki, DOI: 10.1007/s00125-016-3976-6 ) and an overview by the Session Chair, Kerstin Berntorp (DOI: 10.1007/s00125-016-3975-7 ).

    Background Consumption of sugar-sweetened beverage (SSB) has risen over the past two decades, with over 10 million Californians drinking one or more SSB per day. High SSB intake is associated with risk of type 2 diabetes, obesity, hypertension, and coronary heart disease (CHD). Reduction of SSB intake and the potential impact on health outcomes in California and among racial, ethnic, and low-income sub-groups has not been quantified. Methods We projected the impact of reduced SSB consumption on health outcomes among all Californians and California subpopulations from 2013 to 2022. We used the CVD Policy Model – CA, an established computer simulation of diabetes and heart disease adapted to California. We modeled a reduction in SSB intake by 10–20% as has been projected to result from proposed penny-per-ounce excise tax on SSB and modeled varying effects of this reduction on health parameters including body mass index, blood pressure, and diabetes risk. We projected avoided cases of diabetes and CHD, and associated health care cost savings in 2012 US dollars. Results Over the next decade, a 10–20% SSB consumption reduction is projected to result in a 1.8–3.4% decline in the new cases of diabetes and an additional drop of 0.5–1% in incident CHD cases and 0.5–0.9% in total myocardial infarctions. The greatest reductions are expected in African Americans, Mexican Americans, and those with limited income regardless of race and ethnicity. This reduction in SSB consumption is projected to yield $320–620 million in medical cost savings associated with diabetes cases averted and an additional savings of $14–27 million in diabetes-related CHD costs avoided. Conclusions A reduction of SSB consumption could yield substantial population health benefits and cost savings for California. In particular, racial, ethnic, and low-income subgroups of California could reap the greatest health benefits. PMID:24349119

    Abstract This study aimed to examine whether poor glycemic control, measured by glycated hemoglobin A1C (HbA1c) and other cardiovascular risk factors, can predict diabetic peripheral neuropathy (DPN) in patients with type 2 diabetes mellitus (DM). Patients aged ≥30 years with type 2 DM, enrolled in the National Diabetes Care Management Program, and free of DPN (n = 37,375) in the period 2002 to 2004 were included and followed up until 2011. The related factors were analyzed using Cox proportional hazards regression models. For an average follow-up of 7.00 years, 8379 cases of DPN were identified, with a crude incidence rate of 32.04/1000 person-years. After multivariate adjustment, patients with HbA1c levels 7 to 8%, 8 to 9%, 9 to 10%, and ≥10% exhibited higher risk of DPN (adjusted HR: 1.11 [1.04–1.20], 1.30 [1.21–1.40], 1.32 [1.22–1.43], and 1.62 [1.51–1.74], respectively) compared with patients with HbA1c level 6 to 7%. There was a significant linear trend in DPN incidence with increasing HbA1c (P < 0.001) and significant HRs of DPN for patients with HbA1c level ≥7%, blood pressure ≥130/85 mm Hg, triglycerides (TG) ≥150 mg/dL, high density of lipoprotein-cholesterol (HDL-C) <40 mg/dL in males and <50 mg/dL in females, low density of lipoprotein-cholesterol (LDL-C) ≥100 mg/dL, and estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2. Patients with type 2 DM and HbA1c ≥7.0% exhibit increased risk of DPN, demonstrating a linear relationship. The incidence of DPN is also associated with poor glucose control and cardiovascular risk factors like hypertension, hyper-triglyceridemia, low HDL-C, high LDL-C, and decreased eGFR. PMID:26496307

    Abstract The relationship between type 2 diabetes and gout is complex. The objective of this study was to understand the role of diabetes itself and its comorbidities within the association between type 2 diabetes and gout. We conducted a retrospective cohort study using the UK Clinical Practice Research Datalink (CPRD) GOLD. Persons with type 2 diabetes were identified as persons on a noninsulin antidiabetic drug (NIAD) between 2004 and 2012, and were matched to 1 control based on age, sex, and general practice. We estimated gout risk in NIAD users using Cox regression analysis. All analyses were stratified for sex. In total, 221,117 NIAD users were identified. NIAD users had an increased risk of gout (hazard ratio (HR) 1.48; 95% CI 1.41–1.54). This association was stronger in women (HR 2.23; 95% CI 2.07–2.41) compared with men (HR 1.19; 95% CI 1.13–1.26). After adjustments for BMI, eGFR, hypertension, renal transplantation, diuretics, statins, low-dose aspirin, ciclosporin, and tacrolimus, the risk disappeared in women (HR 1.01; 95% CI 0.92–1.11) and reversed in men (HR 0.61; 95% CI 0.58–0.66) (P for interaction <0.001). When stratifying gout risk according to HbA1c in male and female NIAD users, we found an inverse association between raising HbA1c and incident gout in men only. Further adjustment gave similar results. Individuals with type 2 diabetes are at increased risk of gout. This is not due to diabetes itself, but to the comorbid conditions. Diabetes itself is apparently associated with a decreased risk of gout, especially in men. PMID:26266391

  10. Cardiovascular disease risk profile and microvascular complications of diabetes: comparison of Indigenous cohorts with diabetes in Australia and Canada

    PubMed Central

    2012-01-01

    Background Indigenous populations of Australia and Canada experience disproportionately high rates of chronic disease. Our goal was to compare cardiovascular (CVD) risk profile and diabetes complications from three recent comprehensive studies of diabetes complications in different Indigenous populations in Australia and Canada. Methods We compared participants from three recent studies: remote Indigenous Australians (2002-2003, n = 37 known diabetes), urban Indigenous Australians (2003-2005, n = 99 known diabetes), and remote Aboriginal Canadians (2001-2002, n = 188 known diabetes). Results The three groups were similar for HbA1c, systolic BP, diabetes duration. Although leaner by body-mass-index criteria, remote Indigenous Australians displayed a more adverse CVD risk profile with respect to: waist-hip-ratio (1.03, 0.99, 0.94, remote Indigenous Australians, urban Indigenous Australians, remote Canadians, p < 0.001); HDL-cholesterol (0.82, 0.96, 1.17 mmol/L, p < 0.001); urine albumin-creatinine-ratio (10.3, 2.4, 4.5 mg/mmol); and C-reactive protein. With respect to diabetes complications, microalbuminuria (50%, 25%, 41%, p = 0.001) was more common among both remote groups than urban Indigenous Australians, but there were no differences for peripheral neuropathy, retinopathy or peripheral vascular disease. Conclusions Although there are many similarities in diabetes phenotype in Indigenous populations, this comparison demonstrates that CVD risk profiles and diabetes complications may differ among groups. Irrespective, management and intervention strategies are required from a young age in Indigenous populations and need to be designed in consultation with communities and tailored to community and individual needs.

    Introduction Innovative approaches are needed to reduce cardiometabolic risk among American Indian women with a history of gestational diabetes. We assessed beliefs of Oklahoma American Indian women about preventing type 2 diabetes and cardiovascular disease after having gestational diabetes. We also assessed barriers and facilitators to healthy lifestyle changes postpartum and intervention approaches that facilitate participation in a postpartum lifestyle program. Methods In partnership with a tribal health system, we conducted a mixed-method study with American Indian women aged 19 to 45 years who had prior gestational diabetes, using questionnaires, focus groups, and individual interviews. Questionnaires were used to identify women’s cardiometabolic risk perceptions and feasibility and acceptability of Internet or mobile phone technology for delivery of a postpartum lifestyle modification program. Focus groups and individual interviews were conducted to identify key perspectives and preferences related to a potential program. Results Participants were 26 women, all of whom completed surveys; 11 women participated in focus group sessions, and 15 participated in individual interviews. Most women believed they would inevitably develop diabetes, cardiovascular disease, or both; however, they were optimistic that they could delay onset with lifestyle change. Most women expressed enthusiasm for a family focused, technology-based intervention that emphasizes the importance of delaying disease onset, provides motivation, and promotes accountability while accommodating women’s competing priorities. Conclusions Our findings suggest that an intervention that uses the Internet, text messaging, or both and that emphasizes the benefits of delaying disease onset should be tested as a novel, culturally relevant approach to reducing rates of diabetes and cardiovascular disease in this high-risk population.

    Objectives Although type 2 diabetes mellitus is a known risk factor for pancreatic cancer, the existence of shared genetic susceptibility is largely unknown. We evaluated whether any reported genetic risk variants of either disease found by genome-wide association studies reciprocally confer susceptibility. Methods Data that were generated in previous genome-wide association studies (GENEVA Type 2 Diabetes; PanScan) were obtained through the National Institutes of Health database of Genotypes and Phenotypes (dbGaP). Using the PanScan datasets, we tested for association of 38 variants within 37 genomic regions known to be susceptibility factors for type 2 diabetes. We further examined whether type 2 diabetes variants predispose to pancreatic cancer risk stratified by diabetes status. Correspondingly, we examined the association of fourteen pancreatic cancer susceptibility variants within eight genomic regions in the GENEVA Type 2 Diabetes dataset. Results Four plausible associations of diabetes variants and pancreatic cancer risk were detected at a significance threshold of p = 0.05, and one pancreatic cancer susceptibility variant was associated with diabetes risk at threshold of p = 0.05, but none remained significant after correction for multiple comparisons. Conclusion Currently identified GWAS susceptibility variants are unlikely to explain the potential shared genetic etiology between Type 2 diabetes and pancreatic cancer. PMID:25658847

    Background: As food insecurity has negative effects on health, the aim of this study was to determine tahe relationship between household food security and type 2 diabetes mellitus and its related risk factors. Methods: In this case-control study, 200 individuals with and 200 individuals without type 2 diabetes mellitus, aged over 40 years, were randomly selected from among participants of the Tehran Lipid and Glucose Study. The questionnaire on household food security proposed by the United States Department of Agriculture was completed for them by trained personnel. Logistic regression was used to determine the variable that had the most significant relationship with food security status. Results: The average of food security score was 2.38 ± 2.0 in non-diabetic and 2.25 ± 2.0 in diabetic individuals (P = 0.6). In both groups, the risk for food insecurity in women was more than in men. In the diabetic group, being single and having education levels below high school increased the risk of food insecurity. In the non-diabetic group, the risk of food insecurity in obese individuals was 3.3 times higher than normal individuals (odds ratio = 2.1, 95% confidence interval: 1.2–4.1). Conclusions: There were no significant differences in food security levels of diabetic and non-diabetic groups. However, some risk factors of type 2 diabetes including sex, marital status, educational level, and obesity were associated with food insecurity. PMID:26605019

    2016-03-01

    While it is implicitly recognized that the benefits of diagnostic imaging far outweigh any theoretical radiogenic risks, quantitative estimates of the benefits are rarely, if ever, juxtaposed with quantitative estimates of risk. This alone - expression of benefit in purely qualitative terms versus expression of risk in quantitative, and therefore seemingly more certain, terms - may well contribute to a skewed sense of the relative benefits and risks of diagnostic imaging among healthcare providers as well as patients. The current paper, therefore, briefly compares the benefits of diagnostic imaging in several cases, based on actual mortality or morbidity data if ionizing radiation were not employed, with theoretical estimates of radiogenic cancer mortality based on the "linear no-threshold" (LNT) dose-response model.

    Much risk communication research has demonstrated how mass media can influence individual risk perceptions, but lacks a comprehensive conceptual understanding of another key channel of communication: interpersonal discussion. Using the social amplification of risk as a theoretical framework, we consider the potential for discussions to function as amplification stations. We explore this possibility using data from a public opinion survey of residents living in potential locations for a new biological research facility in the United States. Controlling for a variety of key information variables, our results show that two dimensions of discussion-frequency and valence-have impacts on residents' perceptions of the facility's benefits and its risks. We also explore the possibility that an individual's overall attitude moderates the effect of discussion on their perceptions of risks and benefits. Our results demonstrate the potential for discussions to operate as amplifiers or attenuators of perceptions of both risks and benefits. PMID:21039705

    Local public resistance can block the site-selection process, construction, and operation of nuclear waste repositories. Social science has established that the perception of risks and benefits, trust in authorities, and opinion on nuclear energy play important roles in acceptance. In particular, risk and benefit evaluations seem critical for opinion formation. However, risks and benefits have rarely been studied independently and, most often, the focus has been on the two most salient groups of proponents and opponents. The aim of this exploratory study is to examine the often-neglected majority of people holding ambivalent or indifferent opinions. We used cluster analysis to examine the sample (N = 500, mailed survey in German-speaking Switzerland) in terms of patterns of risk and benefit perception. We reveal four significantly different and plausible clusters: one cluster with high-benefit ratings in favor of a repository and one cluster with high-risk ratings opposing it; a third cluster shows ambivalence, with high ratings on both risk and benefit scales and moderate opposition, whereas a fourth cluster seems indifferent, rating risks and benefits only moderately compared to the ambivalent cluster. We conclude that a closer look at the often neglected but considerable number of people with ambivalent or indifferent opinions is necessary. Although the extreme factions of the public will most probably not change their opinion, we do not yet know how the opinion of the ambivalent and indifferent clusters might develop over time.

    PubMed

    2012-04-01

    Several efficacy trials and subsequent dissemination studies indicate that behavioral lifestyle interventions for diabetes risk reduction require, at a minimum, provision of 4 to 6 months of frequent intervention contact to induce clinically meaningful weight losses of at least 5% of initial body weight. Weekly contact during the first several months of intervention, followed by less frequent but regular therapeutic contact for a longer time period, appears necessary for participants to adopt and enact behavioral self-regulatory skills such as the self-monitoring of diet, weight, and physical activity and the problem solving of common physical, social, and cognitive barriers that impede sustained weight loss. In-person contact is associated with the largest effect sizes but may not be a necessary component for clinically meaningful weight loss. Regardless of intervention mode, setting, or provider, the interactive process of feedback and social support is crucial for skill development and sustained weight loss. PMID:22350807

    Background Clinical studies show that metformin attenuates all‐cause mortality and myocardial infarction compared with other medications for type 2 diabetes, even at similar glycemic levels. However, there is paucity of data in the euglycemic state on the vasculoprotective effects of metformin. The objectives of this study are to evaluate the effects of metformin on ameliorating atherosclerosis. Methods and Results Using ApoE−/− C57BL/6J mice, we found that metformin attenuates atherosclerosis and vascular senescence in mice fed a high‐fat diet and prevents the upregulation of angiotensin II type 1 receptor by a high‐fat diet in the aortas of mice. Thus, considering the known deleterious effects of angiotensin II mediated by angiotensin II type 1 receptor, the vascular benefits of metformin may be mediated, at least in part, by angiotensin II type 1 receptor downregulation. Moreover, we found that metformin can cause weight loss without hypoglycemia. We also found that metformin increases the antioxidant superoxide dismutase‐1. Conclusion Pleiotropic effects of metformin ameliorate atherosclerosis and vascular senescence. PMID:25527624

    OBJECTIVE This study aims to investigate predictive risk factors in the treatment of gestational diabetes mellitus (GDM). PATIENTS AND METHODS A total of 256 pregnant women who underwent 75 g oral glucose tolerance test (OGTT) during 24–28 weeks of pregnancy were included according to the World Health Organization criteria. Demographic characteristics of the patients, including age, parity, family history of diabetes, body weight before pregnancy, and body weight at the diagnosis of GDM, were recorded. Fasting insulin and hemoglobin A1c (HbA1c) values at the time of diagnosis were evaluated. The patients were divided into two groups: those requiring insulin treatment (insulin group, n = 89) and those receiving diet therapy (diet group, n = 167) during pregnancy according to the American Diabetes Association recommendations. RESULTS A total of 34.76% of the pregnant women with GDM required insulin treatment. The mean age of these patients was significantly higher compared to the diet group (34.9 ± 0.6 years vs. 31.9 ± 0.6 years; P = 0.004). Body mass index before pregnancy was also significantly higher in the insulin group than that in the diet group (32 ± 0.9 kg/m2 vs. 29 ± 0.7 kg/m2; P = 0.004). Fasting blood glucose (FBG) during OGTT was 105.6 ± 2.1 mg/dL and 96.7 ± 1.1 mg/dL in the insulin group and diet group, respectively (P < 0.001). There was no significant difference in fasting plasma glucose during OGTT between the groups (P = 0.069), while plasma glucose at two hours was 161.1 ± 6.8 mg/dL in the insulin group and 145.1 ± 3.7 mg/dL in the diet group (P = 0.027). At the time of diagnosis, HbA1c values were significantly higher in the insulin group compared to the diet group (5.3 ± 0.1 vs. 4.9 ± 0.1; P = 0.001). There was no significant difference in FBG and homeostasis model assessment-insulin resistance values between the groups (P = 0.908, P = 0.073). CONCLUSION Our study results suggest that age, family history of diabetes, body weight before

    This study explored associations between health status and psychosocial, family, and demographic factors among 42 children with recently diagnosed diabetes mellitus. Health status was assessed using glycosylated hemoglobin (HbA1), a measure of the children's level of metabolic control. Four groups of variables were investigated as possibly relating to metabolic control: demographics, family social climate, child's self-concept, and compliance with the treatment regimen. Metabolic control was associated with race, number of parents in the home, family cohesion, and socioeconomic status. Multiple regression analysis indicated that children from black and single-parent families were at higher risk for poorer disease control and that this pattern persisted 2 and 3 years after diagnosis. These findings can help identify families that may benefit from more effective interventions involving social work practice. PMID:2365239

    Overweight and obesity currently constitute a major threat to human well-being. Almost half of the female population are currently overweight. Pregnant overweight women are at risk of gestational diabetes affecting the health of the mother and the child, in both the short and long term. Notwithstanding the extensive scientific interest centred on the problem, research efforts have thus far been unable to devise preventive strategies. Recent scientific advances point to a gut microbiota dysbiosis, with ensuing low-grade inflammation as a contributing element, in obesity and its comorbidities. Such findings would suggest a role for specific probiotics in the search for preventive and therapeutic adjunct applications in gestational diabetes. The aim of the present paper was to critically review recent demonstrations of the role of intestinal microbes in immune and metabolic regulation, which could be exploited in nutritional management of pregnant women by probiotic bacteria. By modulating specific target functions, probiotic dietary intervention may exert clinical effects beyond the nutritional impact of food. As this approach in pregnancy is new, an overview of the role of gut microbiota in shaping host metabolism, together with the definition of probiotics are presented, and finally, specific targets and potential mechanisms for probiotics in pregnancy are discussed. Pregnancy appears to be the most critical stage for interventions aiming to reduce the risk of non-communicable disease in future generations, beyond the immediate dangers attributable to the health of the mother, labour and the neonate. Specific probiotic interventions during pregnancy provide an opportunity, therefore, to promote the health not only of the mother but also of the child. PMID:25885278

    Type 2 Diabetes (T2D) is a chronic disease arising from the development of insulin absence or resistance within the body, and a complex interplay of environmental and genetic factors. The incidence of T2D has increased throughout the last few decades, together with the occurrence of the obesity epidemic. The consideration of variants identified by Genome Wide Association Studies (GWAS) into risk assessment models for T2D could aid in the identification of at-risk patients who could benefit from preventive medicine. In this study, we build several risk assessment models, evaluated with two different classification approaches (Logistic Regression and Neural Networks), to measure the effect of including genetic information in the prediction of T2D. We used data from to the Original and the Offspring cohorts of the Framingham Heart Study, which provides phenotypic and genetic information for 5245 subjects (4306 controls and 939 cases). Models were built by using several covariates: gender, exposure time, cohort, body mass index (BMI), and 65 SNPs associated to T2D. We fitted Logistic Regressions and Bayesian Regularized Neural Networks and then assessed their predictive ability by using a ten-fold cross validation. We found that the inclusion of genetic information into the risk assessment models increased the predictive ability by 2%, when compared to the baseline model. Furthermore, the models that included BMI at the onset of diabetes as a possible effector, gave an improvement of 6% in the area under the curve derived from the ROC analysis. The highest AUC achieved (0.75) belonged to the model that included BMI, and a genetic score based on the 65 established T2D-associated SNPs. Finally, the inclusion of SNPs and BMI raised predictive ability in all models as expected; however, results from the AUC in Neural Networks and Logistic Regression did not differ significantly in their prediction accuracy.

    Newborn screening has evolved to include an increasingly complex spectrum of diseases, raising concerns that screening should be optional and require parental consent. Early detection of disorders like PKU and MCAD is essential to prevent serious disability and death in affected children. These are examples of high benefit-risk ratio disorders because of the irrefutable health benefits of early detection, coupled with the low risks of treatment. The dire consequences of not diagnosing an infant with a treatable disorder because of parental refusal to screen are wholly unacceptable. Thus, we believe that newborn screening for disorders with high benefit-risk ratios should continue to be mandatory. PMID:27338599

    Return on investment (ROI) is an economic measure used to indicate how much economic benefit is derived from a program in relation to its costs. Interest in the use of ROI in public health has grown substantially over recent years. Given its potential influence on resource allocation, it is crucial to understand the benefits and the risks of using ROI to defend public health programs. In this paper, we explore those benefits and risks. We present two recent examples of ROI use in public health in the United States and Canada and conclude with a series of proposals to minimize the risks associated with using ROI to defend public health interventions.

    A health policy decision often requires a balancing of risks, costs, and benefits. In this paper we illustrate that there is no uniform answer in the United States to the question of who decides the risk-benefit balance. We use a wide range of case examples from medicine and public health to show the different approaches that are used to allocate decision-making responsibility. Our ultimate purpose is to urge the U.S. health policy community to develop a more consistent way of thinking about how risk-benefit decisions could be guided by general principles. PMID:17485737

    Scarce data exist on the relationship between diabetes and extrapulmonary tuberculosis (EPTB). We evaluated whether diabetes impacts site of TB and risk of death in patients with EPTB. We evaluated a cohort of TB cases from the state of Georgia between 2009 and 2012. Patients aged ⩾16 years were classified by diabetes status according to medical records. Site of EPTB was determined by culture and/or state TB classification. Death was defined by all-cause mortality. Of 1325 eligible reported TB cases, 369 (27·8%) had any EPTB including 258 (19·5%) with only EPTB and 111 (8·4%) with pulmonary TB and EPTB. Of all TB cases, 158 had diabetes (11·9%). In multivariable analysis, the odds of any EPTB was similar in patients with and without diabetes [adjusted odds ratio 1·04, 95% confidence interval (CI) 0·70-1·56]. The risk of death was 23·8% in patients with EPTB and diabetes vs. 9·8% in those with no diabetes (P < 0·01); after adjusting for covariates the difference was not significant (aRR 1·19, 95% CI 0·54-2·63). Diabetes was common in patients with EPTB and risk of death was high. Improved understanding of the relationship between diabetes and EPTB is critical to determine the extent that diabetes affects TB diagnosis and clinical management. PMID:26926092

    This study examined how adiposity influences racial/ethnic differences in diabetes incidence by exploring whether relations between anthropometric measures and incident diabetes vary by race/ethnicity. Data from the Multi-Ethnic Study of Atherosclerosis initiated in 2000 (n = 5,446 US men and women aged 45–84 years) were analyzed by using proportional hazards and Poisson regression. The diabetes incidence rate was 2/100 person-years (n = 479 cases). Interactions were present between race and anthropometry (P-interaction(race × body mass index) = 0.002). The slope of incident diabetes per anthropometric unit was greatest for Chinese, less for whites and Hispanics, and still less for blacks. For small waist, risk of incident diabetes was <1/100 person-years for all racial/ethnic groups. At intermediate waist levels, Chinese had the highest and whites the lowest rates of incident diabetes. At the respective 95th percentiles of waist circumference, risk of incident diabetes per 100 person-years was 3.9 for Chinese (104 cm), 3.5 for whites (121 cm), 5.0 for blacks (125 cm), and 5.3 for Hispanics (121 cm). Adiposity influenced relative diabetes occurrence across racial/ethnic groups, in that Chinese had a steeper diabetes risk per unit of adiposity. However, the generally low level of adiposity in Chinese led to a relatively low diabetes occurrence. PMID:20570825

    Foot complications (diabetic foot) are among the most serious and costly complications of diabetes mellitus. Amputation of all or part of a lower extremity is usually preceded by a foot ulcer. To prevent diabetic foot, an automatic non-invasive method to identify patients with diabetes who have a high risk of developing diabetic foot is proposed. To design the proposed method, information concerning social scope and self-care of 153 diabetic patients was presented to the K-means clustering algorithm, which divided the data into two groups: high risk and low risk of developing diabetic foot. In the operational stage, the Euclidian distance from the information vector to the centroids of each group of risk is used as criterion for classification. Both real and simulated data were used to evaluate the method in which promising results were achieved with accuracy of 0.97 ± 0.06 for simulated data and 0.68 ± 0.16 considering the classification of specialists as the gold standard for real data. The method requires a simple computational processing and can be useful for basic health units to triage diabetic patients helping the health-care team to reduce the number of cases of diabetic foot.

    Objectives To investigate the benefits and risks associated with aspirin treatment in patients with type 2 diabetes and no previous cardiovascular disease (CVD) in clinical practice. Design Population-based cohort study between 2005 and 2009, mean follow-up 3.9 years. Setting Hospital outpatient clinics and primary care in Sweden. Participants Men and women with type 2 diabetes, free from CVD, including atrial fibrillation and congestive heart failure, at baseline, registered in the Swedish National Diabetes Register, with continuous low-dose aspirin treatment (n=4608) or no aspirin treatment (n=14 038). Main outcome measures Risks of CVD, coronary heart disease (CHD), stroke, mortality and bleedings, associated with aspirin compared with no aspirin, were analysed in all patients and in subgroups by gender and estimated cardiovascular risk. Propensity scores were used to adjust for several baseline risk factors and characteristics at Cox regression, and the effect of unknown covariates was evaluated in a sensitivity analysis. Results There was no association between aspirin use and beneficial effects on risks of CVD or death. Rather, there was an increased risk of non-fatal/fatal CHD associated with aspirin; HR 1.19 (95% CI 1.01 to 1.41), p=0.04. The increased risk of cardiovascular outcomes associated with aspirin was seen when analysing women separately; HR 1.41 (95% CI 1.07 to 1.87), p=0.02, and HR 1.28 (95% CI 1.01 to 1.61), p=0.04, for CHD and CVD, respectively, but not for men separately. There was a trend towards increased risk of a composite of bleedings associated with aspirin, n=157; HR 1.41 (95% CI 0.99 to 1.99). Conclusions The results support the trend towards more restrictive use of aspirin in patients with type 2 diabetes and no previous CVD. More research is needed to explore the differences in aspirin's effects in women and men. PMID:23604419

    The Food and Drug Administration issued guidance for evaluating the cardiovascular risk of new diabetes mellitus drugs in 2008. Accumulating evidence from several completed trials conducted within this framework raises questions as to whether requiring safety outcome studies for all new diabetes mellitus therapies remains justified. Given the burden of cardiovascular disease in patients with diabetes, the focus should shift towards cardiovascular outcome studies designed to evaluate efficacy (i.e. to determine the efficacy of a drug over placebo or standard care) rather than demonstrating that risk is not increased by a pre-specified safety margin. All stakeholders are responsible for ensuring that new drug approvals occur under conditions of appropriate safety and effectiveness. It is also a shared responsibility to avoid unnecessary hurdles that may compromise access to useful drugs and threaten the sustainability of health systems. It is critical to renew this debate so that stakeholders can collectively determine the optimal approach for developing new drugs to treat type 2 diabetes mellitus. PMID:27418973

    Introduction. Metabolic conditions, including type 2 diabetes, have been related to hepatocellular carcinoma (HCC) risk. We have further analyzed the role of diabetes and antidiabetic treatments on HCC. Methods. Data derived from a hospital-based case-control study (Italy, 2005–2012) on 224 HCC patients and 389 controls. Odds ratios (ORs) were estimated using multiple logistic regression models. Results. Sixty-nine (30.9%) cases versus 52 (13.5%) controls reported a diabetes diagnosis, corresponding to a multivariate OR of 2.25 (95% confidence interval, CI = 1.42–3.56). A stronger excess risk emerged for a longer time since diabetes diagnosis (OR = 2.96 for <10 years and 5.33 for ≥10 years). Oral therapies were inversely, though not significantly, related to HCC risk, OR being 0.44 for metformin and 0.88 for sulfonylureas; conversely, insulin was nonsignificantly directly associated (OR = 1.90). Compared to nondiabetic subjects who were never smokers, those who were diabetics and ever smokers had an OR of 6.61 (95% CI 3.31–13.25). Conclusion. Our study confirms an over 2-fold excess HCC risk in diabetics, with a stronger excess risk in diabetic subjects who are also tobacco smokers. Metformin may decrease the risk of HCC, whereas insulin may increase the risk. PMID:26074956

    Aims Little is known about the long-term effects of intensive multifactorial treatment early in the diabetes disease trajectory. In the absence of long-term data on hard outcomes, we described change in 10-year modelled cardiovascular risk in the 5 years following diagnosis, and quantified the impact of intensive treatment on 10-year modelled cardiovascular risk at 5 years. Methods In a pragmatic, cluster-randomized, parallel-group trial in Denmark, the Netherlands and the UK, 3057 people with screen-detected Type 2 diabetes were randomized by general practice to receive (1) routine care of diabetes according to national guidelines (1379 patients) or (2) intensive multifactorial target-driven management (1678 patients). Ten-year modelled cardiovascular disease risk was calculated at baseline and 5 years using the UK Prospective Diabetes Study Risk Engine (version 3β). Results Among 2101 individuals with complete data at follow up (73.4%), 10-year modelled cardiovascular disease risk was 27.3% (sd 13.9) at baseline and 21.3% (sd 13.8) at 5-year follow-up (intensive treatment group difference –6.9, sd 9.0; routine care group difference –5.0, sd 12.2). Modelled 10-year cardiovascular disease risk was lower in the intensive treatment group compared with the routine care group at 5 years, after adjustment for baseline cardiovascular disease risk and clustering (–2.0; 95% CI –3.1 to –0.9). Conclusions Despite increasing age and diabetes duration, there was a decline in modelled cardiovascular disease risk in the 5 years following diagnosis. Compared with routine care, 10-year modelled cardiovascular disease risk was lower in the intensive treatment group at 5 years. Our results suggest that patients benefit from intensive treatment early in the diabetes disease trajectory, where the rate of cardiovascular disease risk progression may be slowed. PMID:24533664

    Objective To assess the impact of a pharmacy benefit change on mail order pharmacy (MOP) uptake. Data Sources/Study Setting Race-stratified, random sample of diabetes patients in an integrated health care delivery system. Study Design In this natural experiment, we studied the impact of a pharmacy benefit change that conditionally discounted medications if patients used MOP and prepaid two copayments. We compared MOP uptake among those exposed to the benefit change (n = 2,442) and the reference group with no benefit change (n = 8,148), and estimated differential MOP uptake across social strata using a difference-in-differences framework. Data Collection/Extraction Methods Ascertained MOP uptake (initiation among previous nonusers). Principal Findings Thirty percent of patients started using MOP after receiving the benefit change versus 9 percent uptake among the reference group (p < .0001). After adjustment, there was a 26 percentage point greater MOP uptake (benefit change effect). This benefit change effect was significantly smaller among patients with inadequate health literacy (15 percent less), limited English proficiency (14 percent less), and among Latinos and Asians (24 and 16 percent less compared to Caucasians). Conclusions Conditionally discounting medications delivered by MOP effectively stimulated MOP uptake overall, but it unintentionally widened previously existing social gaps in MOP use because it stimulated less MOP uptake in vulnerable populations.

    Psychopharmacology has become a major approach to treatment in primary medical care. However, combined psychiatric and medical illness can give rise to some challenging diagnostic problems. Furthermore, drug treatment of patients with such illnesses can involve important drug-disease interactions and drug-drug interactions. One should keep in mind the issues that arise when an emotionally troubled patient would benefit from a psychotropic drug but a concurrent medical illness complicates this treatment. An awareness of both the medical and psychiatric issues involved may make successful treatment possible. PMID:7269559

    Abstract Increasing evidence suggests that certain types of cancers are more common in people with diabetes mellitus (DM). This study aimed to investigate the risk of skin cancer in patients with DM in Taiwan. In this retrospective cohort study using data from the Taiwan Longitudinal Health Insurance Research Database, the risk of developing overall skin cancer, including nonmelanoma skin cancer (NMSC) and melanoma, was compared by Poisson regression analysis and Cox regression analysis between the DM and non-DM cohorts. The DM cohort with newly diagnosed DM (n = 41,898) and a non-DM cohort were one-to-one matched by age, sex, index date, and comorbidities (coronary artery disease, hyperlipidemia, hypertension, chronic kidney disease, chronic obstructive pulmonary disease, and obesity). Compared with non-DM cohort statistically, for the people with DM aged ≥60 years, the incidence rates of overall skin cancer and NMSC were significantly higher (overall: DM/non-DM: number [n] = 99/76, incidence rate ratio [IRR] = 1.44, P = 0.02; NMSC: DM/non-DM: n = 94/66, IRR = 1.57, P = 0.005). By Cox regression analysis, the risk of developing overall skin cancer or NMSC was significantly higher after adjusting for sex, comorbidities, and overall diseases with immunosuppression status (overall: adjusted hazard ratio [AHR] = 1.46, P = 0.01; NMSC: AHR = 1.6, P = 0.003). Other significant risk factors were older males for skin cancer (overall: AHR = 1.68, P = 0.001; NMSC: AHR = 1.59, P = 0.004; melanoma: AHR = 3.25, P = 0.04), chronic obstructive pulmonary disease for NMSC (AHR = 1.44, P = 0.04), and coronary artery disease for melanoma (AHR = 4.22, P = 0.01). The risk of developing melanoma was lower in the DM cohort than in the non-DM cohort, but without significance (AHR = 0.56, P = 0.28; DM/non-DM: n = 5/10). The incidence rate and risk of developing overall skin cancer, including NMSC, was significantly higher in older adults with DM. Other significant risk factors for older

    Type 2 diabetes in children and adolescents has become a prominent clinical issue in recent decades. Increasing numbers of young people have risk factors for type 2 diabetes, particularly obesity, indicating the need for effective type 2 diabetes prevention strategies. The aim of this review was to identify specific dietary strategies that optimize improvements in risk factors for type 2 diabetes in youth and hence reduce the risk of type 2 diabetes development. Our review of the current literature indicates that dietary interventions lead to weight loss when intervention adherence is high. However, in addition to weight loss, a diet that is reduced in carbohydrates may optimize improvements in other type 2 diabetes risk factors, including insulin resistance and hyperglycemia. While further research is needed to confirm this finding, reduced carbohydrate diets may include a very low-carbohydrate diet, a very low-energy diet, a lower-glycemic-index diet, and/or an intermittent fasting diet. This array of dietary strategies provides a suite of intervention options for clinicians to recommend to young people at risk of type 2 diabetes. However, these findings are in contrast to current guidelines for the prevention of type 2 diabetes in adults which recommends a low-fat, high-carbohydrate diet. PMID:27517953

    Plant derived products are consumed by a large percentage of the population to prevent, delay and ameliorate disease burden; however, relatively little is known about the efficacy, safety and underlying mechanisms of these traditional health products, especially when taken in concert with pharmaceutical agents. The flavonoids are a group of plant metabolites that are common in the diet and appear to provide some health benefits. While flavonoids are primarily derived from soy, many are found in fruits, nuts and more exotic sources, e.g., kudzu. Perhaps the strongest evidence for the benefits of flavonoids in diseases of aging relates to their effect on components of the metabolic syndrome. Flavonoids from soy, grape seed, kudzu and other sources all lower arterial pressure in hypertensive animal models and in a limited number of tests in humans. They also decrease the plasma concentration of lipids and buffer plasma glucose. The underlying mechanisms appear to include antioxidant actions, central nervous system effects, gut transport alterations, fatty acid sequestration and processing, PPAR activation and increases in insulin sensitivity. In animal models of disease, dietary flavonoids also demonstrate a protective effect against cognitive decline, cancer and metabolic disease. However, research also indicates that the flavonoids can be detrimental in some settings and, therefore, are not universally safe. Thus, as the population ages, it is important to determine the impact of these agents on prevention/attenuation of disease, including optimal exposure (intake, timing/duration) and potential contraindications.

    Background The dynamics of physiological and behavioral risk factors of diabetes in rural India is poorly understood. Using data from a health and demographic surveillance site of Birbhum district in West Bengal, India, this study aims to assess the risk factors associated with type 2 diabetes mellitus. Research design and methods A total of 7674 individuals aged ≥18 years participated in a cross-sectional study. Venous plasma glucose method was used for measuring and reporting glucose concentrations in blood, categorized as individuals with diabetes, pre-diabetes or impaired, and normoglycemic. Aside from a set of physiological and behavioral risk factors, a range of socioeconomic confounders of diabetes was computed. Bivariate analysis with χ2 test, and multivariate ordered logit regression methods were deployed to attain the study's objective. Results Overall 2.95% and 3.34% of study participants were diagnosed as individuals with diabetes and pre-diabetes or impaired, respectively. Compared to the poorest, the richest have higher probability (β: 0.730; 95% CI 0.378 to 1.083) of being diagnosed with diabetes. As compared to people with normal body mass index, overweight/obese people are more prone to being diagnosed with diabetes (β: 0.388; 95% CI 0.147 to 0.628). With a decreasing level of physical activity, people are more likely to be diagnosed with diabetes. Conclusions To curb the level of diabetes, this study recommends a culturally sensitive, focused intervention for the adoption of physical activity with more traditional dietary practices, to control the level of overweight/obesity. Attention should be paid to relatively older patients with diabetes or adults with pre-diabetes. PMID:27547420

    We aimed to explore the causal association between type 2 diabetes (T2D) and increased arterial stiffness. We performed a Mendelian randomization (MR) analysis in 11,385 participants from a well-defined community study in Shanghai during 2011-2013. We genotyped 34 T2D-associated common variants identified in East Asians and created a genetic risk score (GRS). We assessed arterial stiffness noninvasively with the measurement of brachial-ankle pulse wave velocity (baPWV). We used the instrumental variable (IV) estimator to qualify the causal relationship between T2D and increased arterial stiffness. We found each 1-SD increase in T2D_GRS was associated with 6% higher risk in increased arterial stiffness (95% CI 1.01, 1.12), after adjustment of other metabolic confounders. Using T2D_GRS as the IV, we demonstrated a causal relationship between T2D and arterial stiffening (odds ratio 1.24, 95% CI 1.06, 1.47; P = 0.008). When categorizing the genetic loci according to their effect on insulin secretion or resistance, we found genetically determined decrease in insulin secretion was associated with increase in baPWV (βIV = 122.3 cm/s, 95% CI 41.9, 204.6; P = 0.0005). In conclusion, our results provide evidence supporting a causal association between T2D and increased arterial stiffness in a Chinese population. PMID:26953161

    Whether the diabetic heart benefits from ischemic preconditioning (IPC), similar to the non-diabetic heart, is a subject of controversy. We recently proposed new roles for iron and ferritin in IPC-protection in Type 1-like streptozotocin-induced diabetic rat heart. Here, we investigated iron homeostasis in Cohen diabetic sensitive rat (CDs) that develop hyperglycemia when fed on a high-sucrose/low-copper diet (HSD), but maintain normoglycemia on regular-diet (RD). Control Cohen-resistant rats (CDr) maintain normoglycemia on either diet. The IPC procedure improved the post-ischemic recovery of normoglycemic hearts (CDr-RD, CDr-HSD and CDs-RD). CDs-HSD hearts failed to show IPC-associated protection. The recovery of these CDs-HSD hearts following I/R (without prior IPC) was better than their RD controls. During IPC ferritin levels increased in normoglycemic hearts, and its level was maintained nearly constant during the subsequent prolonged ischemia, but decayed to its baseline level during the reperfusion phase. In CDs-HSD hearts the baseline levels of ferritin and ferritin-saturation with iron were notably higher than in the controls, and remained unchanged during the entire experiment. This unique and abnormal pattern of post-ischemic recovery of CDs-HSD hearts is associated with marked changes in myocardial iron homeostasis, and suggests that iron and iron-proteins play a causative role/s in the etiology of diabetes-associated cardiovascular disorders.

    Dietary fiber may contribute to both the prevention and treatment of type 2 diabetes mellitus (T2DM). In epidemiological studies the intake of insoluble fiber, but not the intake of soluble fiber, has been inversely associated with the incidence of T2DM. In contrast, in postprandial studies, meals containing sufficiently quantities of beta-glucan, psyllium, or guar gum have decreased insulin and glucose responses in both healthy individuals and patients with T2DM. Diets enriched sufficiently in soluble fiber may also improve overall glycemic control in T2DM. Insoluble fiber has little effect on postprandial insulin and glucose responses. Fiber increases satiety. In some studies, insoluble fiber has been associated with less weight gain over time. Limited cross-sectional evidence suggests an inverse relationship between intake of cereal fiber and whole-grains and the prevalence of the metabolic syndrome. Although long-term data from trials focusing on specifically dietary fiber are lacking, meeting current recommendations for a minimum fiber intake of 25 g/d based on a diet rich in whole grains, fruits and legumes will probably decrease the risk of obesity, the metabolic syndrome and T2DM.

    The rapidly increasing rate of non-insulin-dependent diabetes (NIDDM) among both market economy and developing countries is a worldwide health phenomenon. The number of diabetics worldwide has been projected to increase from 135 million in 1995 to 300 million in 2025. The purpose of this study was to examine the relative effectiveness of three different approaches to the implementation of the Diabetes Prevention Program, a standardized diabetes prevention curriculum, in various worksite organizations within a single community. The methods of implementation selected included an intensive one-on-one counseling approach, a support group meeting approach, and a passive transfer of information approach. The intervention was successful in creating significant mean improvements overall in the participants who completed the 26-week program as follows: (a) reduction in overall mean body weight and mean body mass index, (b) reduction in overall average mean arterial blood pressure, (c) reduction in overall mean diabetes risk score, and (d) increase in overall mean physical activity level. Although the largest proportion of these changes occurred in the one-on-one intervention group, significant changes in some factors were found in all groups. This illustrates the utility of an on-site and incentive-driven approach to diabetes risk factor modification in the workplace. PMID:22763893

    Reducing low-density lipoprotein cholesterol (LDL-C) levels using statins is associated with significant reductions in cardiovascular (CV) events in a wide range of patient populations. Although statins are generally considered to be safe, recent studies suggest they are associated with an increased risk of developing Type 2 diabetes (T2D). This led the US Food and Drug Administration (FDA) to change their labelling requirements for statins to include a warning about the possibility of increased blood sugar and HbA1c levels and the European Medicines Agency (EMA) to issue guidance on a small increased risk of T2D with the statin class. This review examines the evidence leading to these claims and provides practical guidance for primary care physicians on the use of statins in people with or at risk of developing T2D. Overall, evidence suggests that the benefits of statins for the reduction of CV risk far outweigh the risk of developing T2D, especially in individuals with higher CV risk. To reduce the risk of developing T2D, physicians should assess all patients for T2D risk prior to starting statin therapy, educate patients about their risks, and encourage risk-reduction through lifestyle changes. Whether some statins are more diabetogenic than others requires further study. Statin-treated patients at high risk of developing T2D should regularly be monitored for changes in blood glucose or HbA1c levels, and the risk of conversion from pre-diabetes to T2D should be reduced by intensifying lifestyle changes. Should a patient develop T2D during statin treatment, physicians should continue with statin therapy and manage T2D in accordance with relevant national guidelines. PMID:24840509

    Introduction The purpose of this paper is to describe components of a health coaching intervention based on coping skills training delivered via telephone. This intervention was provided to urban adolescents at risk for type 2 diabetes mellitus (T2DM), reinforcing a school-based curriculum designed to promote a healthy lifestyle and prevent T2DM. Method Health coaching via telephone was provided to at-risk, urban youth enrolled in a study of an intervention to reduce risk for T2DM. Vignettes are used to describe the use of several coping skills in this high risk youth population. Results A variety of vignettes illustrate how telephone health coaching reinforced lifestyle changes in students by incorporating coping skills training. Discussion Given the benefits and the challenges of the telephone health coaching intervention, several suggestions for others who plan to use a similar method are described. PMID:21514490

  15. Oseltamivir for influenza infection in children: risks and benefits.

    2016-01-01

    Influenza is a common disease affecting many children each year. In a number of cases, particularly in children <2 years old and in those with severe chronic underlying disease, influenza can be complicated by lower respiratory tract infections, acute otitis media, rhinosinusitis, febrile seizures, dehydration or encephalopathy. Oseltamivir is the influenza virus drug that is most commonly studied in children for both the treatment and prevention of influenza. To avoid the risk that children with mild influenza or patients suffering from different viral infections receive oseltamivir, oseltamivir treatment should be recommended only in severe influenza cases, especially if confirmed by reliable laboratory tests. However, therapy must be initiated considering the risk of complications and the presence of severe clinical manifestations at age- and weight-appropriate doses. Because the vaccine remains the best option for preventing influenza and its complications, prophylaxis using oseltamivir should only be considered in select patients. PMID:26616633

    Abstract The aim of this study was to assess the overall and cause-specific incidences of diabetic hand syndromes (DHS) in patients with diabetes mellitus (DM) by using age and sex stratifications. The DM and control cohorts comprised 606,152 patients with DM and 609,970 age- and sex-matched subjects, respectively, who were followed up from 2000 to 2008. We estimated the incidence densities (IDs) of overall and cause-specific DHS, namely carpal tunnel syndrome (CTS), stenosing flexor tenosynovitis (SFT), limited joint mobility (LJM), and Dupuytren disease (DD), and calculated the hazard ratios (HRs) of DHS in relation to DM by using a Cox proportional hazards model with adjustment for potential confounders. Over a 9-year period, 51,207 patients with DM (8.45%) and 39,153 matched controls (6.42%) sought ambulatory care visits for various DHS, with an ID of 117.7 and 80.7 per 10,000 person-years, respectively. The highest cause-specific ID was observed for CTS, followed by SFT, LJM, and DD, regardless of the diabetic status. After adjustment for potential confounders, patients with DM had a significantly high HR of overall DHS (1.51, 95% confidence interval [CI] = 1.48–1.53). Men and women aged <35 years had the highest HR (2.64, 95% CI = 2.15–3.24 and 2.99, 95% CI = 2.55–3.50, respectively). Cause-specific analyses revealed that DM was more strongly associated with SFT (HR = 1.90, 95% CI = 1.86–1.95) and DD (HR = 1.83, 95% CI = 1.39–2.39) than with CTS (HR = 1.31, 95% CI = 1.28–1.34) and LJM (HR = 1.24, 95% CI = 1.13–1.35). Men and younger patients with DM have the highest risk of DHS. Certain hand syndromes, such as SFT and DD, were more strongly associated with DM than with other syndromes and require the attention of clinicians. PMID:26469895

  17. Initiating insulin therapy in type 2 diabetes: benefits of insulin analogs and insulin pens.

    2008-08-01

    Despite the development of alternative therapies in recent years, insulin injections remain essential treatment for type 2 diabetes once oral therapy alone becomes inadequate. However, neither patients nor physicians are proactive enough with regard to starting insulin, despite the well-known benefits of early insulin initiation and aggressive dose titration. Barriers to starting insulin therapy are being overcome by developments in insulin and delivery device technology and are the subject of this review. A literature search spanning the last 25 years was carried out to identify publications addressing issues of insulin initiation, how insulin analogs can help overcome barriers to initiation, and the advantages of pen-type insulin delivery systems. Seventy-five publications were identified. These references illustrate that the drawbacks associated with regular exogenous human insulins (soluble and NPH) are improved with modern insulin analogs. The more rapid absorption of prandial insulin analogs compared with human insulin eliminates the need for an injection-meal-interval, increasing convenience, while basal analogs have no discernible peak in activity. Modern insulin delivery devices also have advantages over the traditional vial and syringe. Currently available insulin pens are either durable (insulin cartridge is replaceable; e.g., HumaPen, Eli Lilly [Indianapolis, IN]; NovoPen series, Novo Nordisk [Bagsvaerd, Denmark]) or disposable (prefilled; e.g., FlexPen, Novo Nordisk; SoloSTAR, sanofi-aventis [Paris, France]), with features to aid ease-of-use. These include a large dose selector, dial-up and dial-down facility, and audible clicks when selecting the dose. The potential for dosing errors is thus reduced with pen-type devices, with other benefits including a discreet appearance, ease of learning, and greater user confidence. Collectively, these features contribute to overwhelming patient preference when compared with vials and syringes. Despite the greater

This is a medical consensus agreed by an independent panel of experts from the Spanish Society of Diabetes (SED). Several consensuses have been proposed by scientific and medical Societies to achieve clinical goals. However, the risk score for general population may lack sensitivity for individual assessment or for particular groups at risk, such as diabetics. Traditional risk factors together with non-traditional factors are reviewed throughout this paper. Intervention strategies for managing CVRF in the diabetic patient are reviewed in detail: balanced food intake, weight reduction, physical exercise, smoking cessation, reduction in HbA1c, therapy for high blood pressure, obesity, lipid disorders, and platelet anti-aggregation. It is hoped that these guidelines can help clinicians in the decisions of their clinical activity. This regular update by the SED Cardiovascular Disease Group of the most relevant concepts, and of greater practical and realistic clinical interest, is presented in order to reduce CVR of diabetics.

    Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are effective and widely used antihypertensive drugs. Exposure to these agents is known to be harmful to the fetus in the second and third trimesters of pregnancy. Concerns have also been raised about the risk of congenital malformations if ACEIs or ARBs are taken during the first trimester of pregnancy. The evidence to date, however, is conflicting and observed malformations may be due to confounders such as undiagnosed diabetes or maternal obesity, other antihypertensive medications or the hypertension itself. Nonetheless, in women who become pregnant while taking an ACEI or ARB, the drug should be stopped as soon as possible. In women with chronic kidney disease and proteinuria, it may be appropriate to continue taking an ACEI or ARB until the pregnancy is confirmed because of the significant benefit to their kidney function and the lower fertility rate in these patients.

    Objective: The aims of the study were to investigate the prevalence of pre-diabetes and explore its associated risk factors in rural areas of Ningbo, China. Methods: A cross-sectional survey was conducted with 4583 adult residents in rural areas of Ningbo, China between March and May 2013. The survey used a multi-stage, stratified, cluster sampling method. Data collected included demographics and medical history, anthropometric measurements, blood pressure, blood lipid, and plasma glucose. After at least 10 h of overnight fasting, participants underwent an oral glucose tolerance test (OGTT) to identify pre-diabetes. Univariate and multivariate logistic regression analyses were used to evaluate the associated risk factors for pre-diabetes, and to estimate the effect of interaction between the factors. Results: There were 1307 survey participants having pre-diabetes (28.52%) and the age-standardized prevalence was 30.53%. Multivariate logistic regression results showed that overweight/obesity, hypertension, and higher triglycerides were the risk factors for developing pre-diabetes. There were positive interactions between overweight/obesity and triglycerides, and also between hypertension and triglycerides on the multiplicative scale, suggesting that they synergistically influenced the development of pre-diabetes. Conclusions: The rural areas in Ningbo had a high prevalence of pre-diabetes. Overweight and obesity, hypertension, and elevated triglycerides were the major risk factors. There is a need of early intervention for preventing pre-diabetes. PMID:27517947

    2015-06-01

    The control and prevention of bovine viral diarrhea virus (BVDV) infections has provided substantial challenges. Viral genetic variation, persistent infections, and viral tropism for immune cells have complicated disease control strategies. Vaccination has, however, provided an effective tool to prevent acute systemic infections and increase reproductive efficiency through fetal protection. There has been substantial controversy about the safety and efficacy of BVDV vaccines, especially when comparing killed versus modified-live viral (MLV) vaccines. Furthermore, numerous vaccination protocols have been proposed to protect the fetus and ensure maternal antibody transfer to the calf. These issues have been further complicated by reports of immune suppression during natural infections and following vaccination. While killed BVDV vaccines provide the greatest safety, their limited immunogenicity makes multiple vaccinations necessary. In contrast, MLV BVDV vaccines induce a broader range of immune responses with a longer duration of immunity, but require strategic vaccination to minimize potential risks. Vaccination strategies for breeding females and young calves, in the face of maternal antibody, are discussed. With intranasal vaccination of young calves it is possible to avoid maternal antibody interference and induce immune memory that persists for 6-8 months. Thus, with an integrated vaccination protocol for both breeding cows and calves it is possible to maximize disease protection while minimizing vaccine risks. PMID:26050569

    This study aimed to examine whether poor glycemic control, measured by glycated hemoglobin A1C (HbA1c) and other cardiovascular risk factors, can predict diabetic peripheral neuropathy (DPN) in patients with type 2 diabetes mellitus (DM).Patients aged ≥30 years with type 2 DM, enrolled in the National Diabetes Care Management Program, and free of DPN (n = 37,375) in the period 2002 to 2004 were included and followed up until 2011. The related factors were analyzed using Cox proportional hazards regression models.For an average follow-up of 7.00 years, 8379 cases of DPN were identified, with a crude incidence rate of 32.04/1000 person-years. After multivariate adjustment, patients with HbA1c levels 7 to 8%, 8 to 9%, 9 to 10%, and ≥10% exhibited higher risk of DPN (adjusted HR: 1.11 [1.04-1.20], 1.30 [1.21-1.40], 1.32 [1.22-1.43], and 1.62 [1.51-1.74], respectively) compared with patients with HbA1c level 6 to 7%. There was a significant linear trend in DPN incidence with increasing HbA1c (P < 0.001) and significant HRs of DPN for patients with HbA1c level ≥7%, blood pressure ≥130/85 mm Hg, triglycerides (TG) ≥150 mg/dL, high density of lipoprotein-cholesterol (HDL-C) <40 mg/dL in males and <50 mg/dL in females, low density of lipoprotein-cholesterol (LDL-C) ≥100 mg/dL, and estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m.Patients with type 2 DM and HbA1c ≥7.0% exhibit increased risk of DPN, demonstrating a linear relationship. The incidence of DPN is also associated with poor glucose control and cardiovascular risk factors like hypertension, hyper-triglyceridemia, low HDL-C, high LDL-C, and decreased eGFR. PMID:26496307

    The main aim of this study is to determine the prevalence and risk factors of ischemic stroke among diabetic patients registered in the Saudi National Diabetes Registry (SNDR) database. A cross-sectional sample of 62,681 diabetic patients aged ≥25 years was used to calculate ischemic stroke prevalence and its risk factors. Univariate and multivariate logistic regression analyses were used to assess the roles of different risk factors. The prevalence of ischemic stroke was 4.42% and was higher in the older age group with longer diabetes duration. Poor glycemic control and the presence of chronic diabetes complications were associated with a high risk of ischemic stroke. History of smoking and type 2 diabetes were more frequent among stroke patients. Obesity significantly decreased the risk for ischemic stroke. Regression analysis for ischemic stroke risk factors proved that age ≥45 years, male gender, hypertension, coronary artery disease (CAD), diabetes duration ≥10 years, insulin use, and hyperlipidemia were significant independent risk factors for ischemic stroke. We conclude that ischemic stroke is prevalent among diabetic individuals, particularly among those with type 2 diabetes. Good glycemic, hypertension, and hyperlipidemia control, in addition to smoking cessation, are the cornerstones to achieve a significant reduction in ischemic stroke risk. PMID:26989695

    Background The prevalence of type 2 diabetes (T2D) is increasing in the Middle East. However, the genetic risk factors for T2D in the Middle Eastern populations are not known, as the majority of studies of genetic risk for T2D are in Europeans and Asians. Methods All subjects were ≥3 generation Qataris. Cases with T2D (n = 1,124) and controls (n = 590) were randomly recruited and assigned to the 3 known Qatari genetic subpopulations [Bedouin (Q1), Persian/South Asian (Q2) and African (Q3)]. Subjects underwent genotyping for 37 single nucleotide polymorphisms (SNPs) in 29 genes known to be associated with T2D in Europeans and/or Asian populations, and an additional 27 tag SNPs related to these susceptibility loci. Pre-study power analysis suggested that with the known incidence of T2D in adult Qataris (22%), the study population size would be sufficient to detect significant differences if the SNPs were risk factors among Qataris, assuming that the odds ratio (OR) for T2D SNPs in Qatari’s is greater than or equal to the SNP with highest known OR in other populations. Results Haplotype analysis demonstrated that Qatari haplotypes in the region of known T2D risk alleles in Q1 and Q2 genetic subpopulations were similar to European haplotypes. After Benjamini-Hochberg adjustment for multiple testing, only two SNPs (rs7903146 and rs4506565), both associated with transcription factor 7-like 2 (TCF7L2), achieved statistical significance in the whole study population. When T2D subjects and control subjects were assigned to the known 3 Qatari subpopulations, and analyzed individually and with the Q1 and Q2 genetic subpopulations combined, one of these SNPs (rs4506565) was also significant in the admixed group. No other SNPs associated with T2D in all Qataris or individual genetic subpopulations. Conclusions With the caveats of the power analysis, the European/Asian T2D SNPs do not contribute significantly to the high prevalence of T2D in the Qatari population, suggesting

    Objectives Glycated haemoglobin A1c (HbA1c) measurement is recommended as an alternative to fasting plasma glucose (FPG) for the diagnosis of pre-diabetes and type 2 diabetes. However, evidence suggests discordance between HbA1c and FPG. In this study we examine a range of metabolic risk features, pro-inflammatory cytokines, acute-phase response proteins, coagulation factors and white blood cell counts to determine which assay more accurately identifies individuals at increased cardiometabolic risk. Materials and Methods This was a cross-sectional study involving a random sample of 2,047 men and women aged 46-73 years. Binary and multinomial logistic regression were employed to examine risk feature associations with pre-diabetes [either HbA1c levels 5.7-6.4% (39-46 mmol/mol) or impaired FPG levels 5.6-6.9 mmol/l] and type 2 diabetes [either HbA1c levels >6.5% (>48 mmol/mol) or FPG levels >7.0 mmol/l]. Receiver operating characteristic curve analysis was used to evaluate the ability of HbA1c to discriminate pre-diabetes and diabetes defined by FPG. Results Stronger associations with diabetes-related phenotypes were observed in pre-diabetic subjects diagnosed by FPG compared to those detected by HbA1c. Individuals with type 2 diabetes exhibited cardiometabolic profiles that were broadly similar according to diagnosis by either assay. Pre-diabetic participants classified by both assays displayed a more pro-inflammatory, pro-atherogenic, hypertensive and insulin resistant profile. Odds ratios of having three or more metabolic syndrome features were also noticeably increased (OR: 4.0, 95% CI: 2.8-5.8) when compared to subjects diagnosed by either HbA1c (OR: 1.4, 95% CI: 1.2-1.8) or FPG (OR: 3.0, 95% CI: 1.7-5.1) separately. Conclusions In middle-aged Caucasian-Europeans, HbA1c alone is a poor indicator of cardiometabolic risk but is suitable for diagnosing diabetes. Combined use of HbA1c and FPG may be of additional benefit for detecting individuals at highest odds of

    The objective of this study was to compare the amount of self-reported physical activity, alcohol and tobacco use in a large sample of adults with type 1 diabetes and non-diabetic subjects. A second aim is to test the hypothesis that these lifestyle risk factors are associated cross-sectionally with coronary artery calcification. In 2000-2002, the Coronary Artery Calcification in Type 1 Diabetes (CACTI) study applied validated questionnaires for smoking, alcohol and physical activity to 582 type 1 diabetes subjects and 724 non-diabetic subjects. More type 1 diabetes subjects reported current smoking than non-diabetic subjects (12.3% versus 8.6%, p=0.027). Overall, reported physical activity did not differ by diabetes status (p=0.79). More type 1 diabetes subjects reported never having consumed alcohol (10% versus 4%, p<0.0001) and those who drank consumed less alcohol (p=0.0015) than non-diabetic subjects. Physical activity and smoking were significantly associated with the presence of coronary artery calcification (adjusted OR=0.9, 95% CI: 0.8-0.996, p=0.045, and OR=1.7, CI: 1.1-2.6, p=0.03, respectively). Type 1 diabetes was independently associated with increased odds of coronary artery calcification (OR=3.5, 95% CI: 2.5-5.0, p<0.0001). Differences exist in lifestyle-related cardiovascular risk factors in men and women with type 1 diabetes compared with non-diabetic subjects in the CACTI study. PMID:20368221

    Approximately 466,000 West Virginians, or about 25 percent of the state population, have prediabetes and are at high risk for developing type 2 diabetes. Appropriate lifestyle intervention can prevent or delay the onset of type 2 diabetes if individuals at risk are identified and treated early. The West Virginia Diabetes Prevention and Control Program and the West Virginia University Office of Health Services Research are developing a systematic approach to diabetes prevention within primary care. This study aims to demonstrate the viability of patient registry software for the analysis of disparate electronic health record (EHR) data sets and standardized identification of at-risk patients for early detection and intervention. Preliminary analysis revealed that of 94,283 patients without a documented diagnosis of diabetes or prediabetes, 10,673 (11.3 percent) meet one or more of the risk criteria. This study indicates that EHR data can be repurposed into an actionable registry for prevention. This model supports meaningful use of EHRs, the Patient-Centered Medical Home program, and improved care through enhanced data management. PMID:24159274

  13. Prenatal treatment of congenital adrenal hyperplasia: risks outweigh benefits.

    2013-05-01

    Prenatal treatment of congenital adrenal hyperplasia by administering dexamethasone to a woman presumed to be carrying an at-risk fetus has been described as safe and effective in several reports. A review of data from animal experimentation and human trials indicates that first-trimester dexamethasone decreases birthweight; affects renal, pancreatic beta cell, and brain development; increases anxiety; and predisposes to adult hypertension and hyperglycemia. In human studies, first-trimester dexamethasone is associated with orofacial clefts, decreased birthweight, poorer verbal working memory, and poorer self-perception of scholastic and social competence. Numerous medical societies have cautioned that prenatal treatment of congenital adrenal hyperplasia with dexamethasone should only be done in prospective clinical research settings with institutional review board approval, and therefore is not appropriate for routine community practice.

  14. Dietary nitrate and nitrite: Benefits, risks, and evolving perceptions.

    Consumers have an illogical relationship with nitrite (and its precursor, nitrate) in food. Despite a long history of use, nitrite was nearly banned from use in foods in the 1970s due to health concerns related to the potential for carcinogenic nitrosamine formation. Changes in meat processing methods reduced those potential risks, and nitrite continued to be used in foods. Since then, two opposing movements continue to shape how consumers view dietary nitrate and nitrite. The discovery of the profound physiological importance of nitric oxide led to the realization that dietary nitrate contributes significantly to the nitrogen reservoir for nitric oxide formation. Numerous clinical studies have also demonstrated beneficial effects from dietary nitrate consumption, especially in vascular and metabolic health. However, the latest wave of consumer sentiment against food additives, the clean-label movement, has renewed consumer fear and avoidance of preservatives, including nitrite. Education is necessary but may not be sufficient to resolve this disconnect in consumer perception. PMID:26994928

    The proportion of older patients accepted for dialysis is increasing every year both in the US and abroad. Of the two treatment modalities for end-stage renal disease, i.e. dialysis and transplantation, the latter offers more freedom and is associated with better clinical outcome. Most elderly patients seem to have excellent functional rehabilitation after a kidney transplant. However, in view of the wide gap between the availability of cadaver organs and the people in need, giving the precious organ to the elderly who have a shorter expected lifespan may present an ethical problem. Therefore, it has become increasingly important to offer the kidney to only those who have no significant comorbid conditions or other high risk factors, so as to improve the odds of success after renal transplantation.

    There is a growing body of evidence to support a connection between diabetes (predominantly type 2), obesity and cancer. Multiple meta-analyses of epidemiological data show that people with diabetes are at increased risk of developing many different types of cancers, along with an increased risk of cancer mortality. Several pathophysiological mechanisms for this relationship have been postulated, including insulin resistance and hyperinsulinaemia, enhanced inflammatory processes, dysregulation of sex hormone production and hyperglycaemia. In addition to these potential mechanisms, a number of common risk factors, including obesity, may be behind the association between diabetes and cancer. Indeed, obesity is associated with an increased risk of cancer and diabetes. Abdominal adiposity has been shown to play a role in creating a systemic pro-inflammatory environment, which could result in the development of both diabetes and cancer. Here, we examine the relationship between diabetes, obesity and cancer, and investigate the potential underlying causes of increased cancer risk in individuals with diabetes. Current treatment recommendations for reducing the overall disease burden are also explored and possible areas for future research are considered. PMID:23668396

    The sequencing of the human genome and technological advances in DNA sequencing have led to a revolution with respect to DNA sequencing and its potential to diagnose genetic disorders. However, requests for open access to genomic data must be balanced against the guiding principles of the Common Rule for human subject research. Unfortunately, the risks to patients involved in genomic studies are still evolving and as such may not be clear to learned and well-intentioned scientists. Central to this issue are the strategies that enable human participants in such studies to remain anonymous, or de-identified. The wealth of genomic data on the Internet in genomic data repositories and other databases has enabled de-identified data to be broken and research subjects to be identified. The security of de-identification neglects the fact that DNA itself is an identifying element. Therefore, it is questionable whether data security standards can ever truly protect the identity of a patient, under the current conditions or in the future. As Big Data methodologies advance, additional sources of data may enable the re-identification of patients enrolled in next-generation sequencing (NGS) studies. As such, it is time to re-evaluate the risks of sharing genomic data and establish new guidelines for good practices. In this commentary, I address the challenges facing federally funded investigators who need to strike a balance between compliance with federal (US) rules for human subjects and the recent requirement for open access/sharing of data from National Institute for Health (NIH)-funded studies involving human subjects.

    A critical review of the literature about risks and benefits of the removal of impacted 3rd molar teeth is presented in 4 categories: risk of non-intervention, risk of intervention, benefit of non-intervention and benefit of intervention. There are well-defined criteria for removal of impacted 3rd molar teeth. Absolute indications and contra-indications for the removal of asymptomatic 3rd molar teeth cannot be established because no long-term studies exist which validate the benefit to the patient either of early removal or of deliberate retention of these teeth. The prudent course of action for the clinician to follow is based on rational clinical decision-making using traditional methods of evaluation to effect the optimal outcome, keeping the interests of the individual patient above all else.

    Dietary patterns and lifestyle factors are clearly associated with at least five of the ten leading causes of death, including coronary heart disease, certain types of cancer, stroke, non-insulin insulin-dependent diabetes mellitus, and atherosclerosis. Concerning specifically fish and seafood consumption, its beneficial health effects in humans are clearly supported by an important number of studies performed in the last 30 years. These studies have repeatedly linked fish consumption, especially those species whose contents in omega-3 fatty acids are high, with healthier hearts in the aging population. The nutritional benefits of fish and seafood are also due to the content of high-quality protein, vitamins, as well as other essential nutrients. However, a number of studies, particularly investigations performed in recent years, have shown that the unavoidable presence of environmental contaminants in fish and shellfish can also mean a certain risk for the health of some consumers. While prestigious international associations as the American Heart Association have recommended eating fish at least two times (two servings a week), based on our own experimental results, as well as in results from other laboratories, we cannot be in total agreement with that recommendation. Although a regular consumption of most fish and shellfish species should not mean adverse health effects for the consumers, the specific fish and shellfish species consumed, the frequency of consumption, as well as the meal size, are essential issues for adequately balancing the health benefits and risks of regular fish consumption.

    The US Department of Energy has established the Tank Waste Remediation System (TWRS) program to safely manage wastes currently stored in underground tank at the Hanford Site. A TWRS testing and development strategy was recently developed to define long-range TWRS testing plans. The testing and development strategy considered four alternatives. The primary variable in the alternatives is the level of pilot-scale testing involving actual waste. This study evaluates the cost benefit and risks associated with the four alternatives. Four types of risk were evaluated: programmatic schedule risk, process mishap risk, worker risk, and public health risk. The structure of this report is as follows: Section 1 introduces the report subject; Section 2 describes the test strategy alternative evaluation; Section 3 describes the approach used in this study to assess risk and cost benefit; Section 4 describes the assessment methodologies for costs and risks; Section 5 describes the bases and assumptions used to estimate the costs and risks; Section 6 presents the detailed costs and risks; and Section 7 describes the results of the cost benefit analysis and presents conclusions.

  1. Health benefits of 'grow your own' food in urban areas: implications for contaminated land risk assessment and risk management?

    Compelling evidence of major health benefits of fruit and vegetable consumption, physical activity, and outdoor interaction with 'greenspace' have emerged in the past decade - all of which combine to give major potential health benefits from 'grow-your-own' (GYO) in urban areas. However, neither current risk assessment models nor risk management strategies for GYO in allotments and gardens give any consideration to these health benefits, despite their potential often to more than fully compensate the risks. Although urban environments are more contaminated by heavy metals, arsenic, polyaromatic hydrocarbons and dioxins than most rural agricultural areas, evidence is lacking for adverse health outcomes of GYO in UK urban areas. Rarely do pollutants in GYO food exceed statutory limits set for commercial food, and few people obtain the majority of their food from GYO. In the UK, soil contamination thresholds triggering closure or remediation of allotment and garden sites are based on precautionary principles, generating 'scares' that may negatively impact public health disproportionately to the actual health risks of exposure to toxins through own-grown food. By contrast, the health benefits of GYO are a direct counterpoint to the escalating public health crisis of 'obesity and sloth' caused by eating an excess of saturated fats, inadequate consumption of fresh fruit and vegetables combined with a lack of exercise. These are now amongst the most important preventable causes of illness and death. The health and wider societal benefits of 'grow-your-own' thus reveal a major limitation in current risk assessment methodologies which, in only considering risks, are unable to predict whether GYO on particular sites will, overall, have positive, negative, or no net effects on human health. This highlights a more general need for a new generation of risk assessment tools that also predict overall consequences for health to more effectively guide risk management in our

    Type 2 diabetes is a serious and common chronic disease resulting from a complex inheritance-environment interaction along with other risk factors such as obesity and sedentary lifestyle. Type 2 diabetes and its complications constitute a major worldwide public health problem, affecting almost all populations in both developed and developing countries with high rates of diabetes-related morbidity and mortality. The prevalence of type 2 diabetes has been increasing exponentially, and a high prevalence rate has been observed in developing countries and in populations undergoing “westernization” or modernization. Multiple risk factors of diabetes, delayed diagnosis until micro- and macro-vascular complications arise, life-threatening complications, failure of the current therapies, and financial costs for the treatment of this disease, make it necessary to develop new efficient therapy strategies and appropriate prevention measures for the control of type 2 diabetes. Herein, we summarize our current understanding about the epidemiology of type 2 diabetes, the roles of genes, lifestyle and other factors contributing to rapid increase in the incidence of type 2 diabetes. The core aims are to bring forward the new therapy strategies and cost-effective intervention trials of type 2 diabetes. PMID:25249787

    Diabetes mellitus (DM) is a major worldwide health problem and its prevalence has been rapidly increasing in the last century. It is caused by defects in insulin secretion or insulin action or both, leading to hyperglycemia. Of the various types of DM, type 2 occurs most frequently. Multiple genes and their interactions are involved in the insulin secretion pathway. Insulin secretion is mediated through the ATP-sensitive potassium (KATP) channel in pancreatic beta cells. This channel is a heteromeric protein, composed of four inward-rectifier potassium ion channel (Kir6.2) tetramers, which form the pore of the KATP channel, as well as sulfonylurea receptor 1 subunits surrounding the pore. Kir6.2 is encoded by the potassium inwardly rectifying channel, subfamily J, member 11 (KCNJ11) gene, a member of the potassium channel genes. Numerous studies have reported the involvement of single nucleotide polymorphisms of the KCNJ11 gene and their interactions in the susceptibility to DM. This review discusses the current evidence for the contribution of common KCNJ11 genetic variants to the development of DM. Future studies should concentrate on understanding the exact role played by these risk variants in the development of DM. PMID:26448950

    Few and contrasting data have reported vascular endothelial dysfunction and increased serum levels of endothelial dysfunction and inflammatory markers in women with previous gestational diabetes mellitus (pGDM). We aimed at evaluating 6.5 years after delivery: intimal medial thickness (IMT), and C-reactive protein (CRP), interleukin-6 (IL-6), E-selectin, intercellular adhesion molecule-1 (ICAM-1), vascular adhesion molecule-1 (VCAM-1) levels in 82 non-pregnant pGDM and 113 control women without pGDM. A subgroup of 21 women, taken from the pGDM group, showing current normal BMI, and no metabolic abnormalities, was separately analysed. All the subjects were free of medication and non-smokers. Women with pGDM, independently by their current BMI and presence of metabolic abnormalities, showed significantly higher E-selectin, ICAM-1 and IMT values than controls. IMT proved to be significantly associated with pGDM in a regression model, after adjustments for BMI, waist circumference, blood pressure, and glucose values (beta=0.046; 95% CI 0.028-0.064). In all pGDM women, E-selectin, ICAM-1, IL-6 and hs-CRP values were significantly associated with IMT in the same model. Post-GDM women, despite being currently free from metabolic abnormalities, showed higher values of markers of endothelial dysfunction and IMT than controls, consistent with an increased future cardiovascular risk.

    Vitamin D is well known for its role in calcium regulation and bone health, but emerging literature tells of vitamin D’s central role in other vital body processes, such as: signaling gene response, protein synthesis, hormone synthesis, immune response, plus, cell turnover and regeneration. The discovery of the vitamin D receptor within the muscle suggested a significant role for vitamin D in muscle tissue function. This discovery led researchers to question the impact that vitamin D deficiency could have on athletic performance and injury. With over 77% of the general population considered vitamin D insufficient, it’s likely that many athletes fall into the same category. Research has suggested vitamin D to have a significant effect on muscle weakness, pain, balance, and fractures in the aging population; still, the athletic population is yet to be fully examined. There are few studies to date that have examined the relationship between vitamin D status and performance, therefore, this review will focus on the bodily roles of vitamin D, recommended 25(OH)D levels, vitamin D intake guidelines and risk factors for vitamin D insufficiency in athletes. In addition, the preliminary findings regarding vitamin D’s impact on athletic performance will be examined. PMID:23760056

    Short-acting beta(2)-agonists are the mainstay of therapy for acute bronchospasm associated with asthma and chronic obstructive pulmonary disease, whereas long-acting beta(2)-agonists are used in maintaining disease control in these respiratory disorders. This review describes and compares the pharmacology of the beta(2)-agonists and explains how these differences translate into differences in efficacy and beta(2)-adrenergic-mediated adverse effects. Questions commonly asked by clinicians regarding the efficacy and safety of short- and long-acting beta(2)-agonists include issues about cardiovascular effects, tolerance to their bronchodilator and bronchoprotective effects, blunting of albuterol response by long-acting beta(2)-agonists, potential masking of worsening asthma control, and the role of long-acting beta(2)-agonists as adjunctive therapy with inhaled corticosteroids in maintaining asthma control. Pharmacogenetics may play a role in determining which patients may be at risk for a reduced response to a beta(2)-agonist. The continued use of racemic albuterol, which contains a mixture of R-albuterol and S-albuterol, has been questioned because of data from preclinical and clinical studies suggesting that S-albuterol causes proinflammatory effects and may increase bronchial hyperreactivity. The preclinical and clinical effects of these two stereoisomers are reviewed. Data describing the efficacy and safety of levalbuterol (R-albuterol) and racemic albuterol are presented. PMID:16945063

    2009-07-01

    Adult gains in body weight, excess adiposity, and intra-abdominal fat have each been associated with risk for type 2 diabetes mellitus (T2DM), forming the basis for preventive medicine guidelines and actuarial predictions using practical indices of weight (e.g., body mass index [BMI]) and waist circumference (WC). As obesity-related disease spreads beyond affluent western countries, application of WC thresholds to other populations has highlighted issues of their generalizability. For example, U.S. national health goals based on BMI < 25 kg/m(2) and WC < 89 cm (women) and <102 cm (men) differ considerably with a recent law in Japan mandating intervention for older adults with WC exceeding 90 cm (women) and 85 cm (men). The U.S. military has also faced issues of generalizability of WC-based adiposity standards that are fair and achievable. Data from many studies indicate that WC is a reliable biomarker for T2DM risk, suggesting that, for adult men and women, action thresholds should be more stringent than current U.S. guidelines, and it would not be harmful to set worldwide targets somewhere below 90 cm for men and women, regardless of weight status. Medical technology has provided many great insights into disease, including modern imaging technologies that have differentiated fat depots that have the greatest influence on T2DM, but ultimately, an inexpensive measuring tape provides the most useful and cost-effective preventive measure for T2DM today. At some point in the future, a Star Trek-like abdominal body fat "tricorder" noninvasive assessment of tissue composition may provide an advantage over abdominal girth. PMID:20144326

    Accumulating evidence suggests that negative perceptions towards diabetes can limit the management and prevention of the disease. The negative perceptions towards diabetes are prevalent in many different settings, especially among rural communities. Few qualitative studies have been performed to understand how the community views diabetes and its associated risk factors. This study aimed to explore general community perceptions of diabetes and its risk factors in rural Indonesia. A total of 68 participants were recruited to 12 focus group discussions (FGDs) comprised of different age groups and sexes. The FGDs were conducted in six villages in rural Purworejo District, Central Java, Indonesia, from 2011 to 2012. All FGDs were recorded and transcribed. Qualitative content analysis was performed to describe and analyse how the rural community perceived diabetes and its risk factors. Diabetes was perceived as a visible and scary sugar disease, and the affected individuals themselves were blamed for getting the disease. Recognised as 'sugar' or 'sweet-pee' disease with terrifying effects, diabetes was believed to be a disease with no cure. The participants seemed to have an unrealistic optimism with regards to the diabetes risk factors. They believed that diabetes would not affect them, only others, and that having family members with diabetes was necessary for one to develop diabetes. Our findings demonstrate that rural communities have negative perceptions about diabetes and at the same time individuals have unrealistic optimism about their own risk factors. Understanding how such communities perceive diabetes and its risk factors is important for planning prevention strategies. Health messages need to be tailored to health-related behaviours and the local culture's concepts of diseases and risk factors. PMID:25168994

    1994-02-01

    In this paper, we propose a method to discount the observed benefit of a treatment by the observed risk in order to facilitate the benefit-less-risk comparison of treatments in a clinical trial. The discounting, applied to each individual in a trial, utilizes a method proposed by Chuang-Stein and co-authors to consolidate the safety data collected in the trial. The collating of the safety information allows one to estimate quantitatively the risk experienced by each individual, and therefore enables the construction of a risk-adjusted benefit measure for the same individual. We discuss the rationale for the adjusting method and examine its impact on the inference. When the discounting process reflects an individual's choice, the results should be interpreted at the individual level. An example is given to illustrate the approach. PMID:7908619

    The global obesity epidemic continues unabated, now rapidly expanding to developing countries. Multiple comorbidities and premature mortality are associated with obesity, most frequently diabetes. The associated financial and economical burden is escalating as well. The sedentary lifestyle adopted by many pregnant women because of traditional practices and the current recommendation for gestational weight gain are contributing factors to the obesity and diabetes epidemic. Physical inactivity is recognized as an independent risk factor for obesity insulin resistance and type 2 diabetes; the physiological and hormonal changes associated with pregnancy magnify this risk. Conversely, evidence and accumulated experience indicate that antenatal lifestyle interventions that include physical activity and judicious dieting could improve the pregnancy outcome and reduce the risk of gestational diabetes and is effective as an adjunctive therapy for diabetes in pregnancy. All major professional organizations, among them American Congress of Obstetricians and Gynecologists (ACOG), American Diabetes Association (ADA), Royal College of Obstetricians and Gynaecologists (RCOG), and Society of Obstetricians and Gynaecologists of Canada (SOGC), recommend lifestyle interventions that include diet and exercise to prevent or manage gestational diabetes or diabetes mellitus.

    Objectives. To assess thyroid function and associated risk factors in Nepalese diabetes mellitus patients. Methods. A cross-sectional study was carried out among 419 diabetes mellitus patients at B. P. Koirala Institute of Health Sciences, Dharan, Nepal. Information on demographic and anthropometric variables and risk factors for thyroid dysfunction was collected. Blood samples were analysed to measure thyroid hormones, blood sugar, and lipid profile. Results. Prevalence rate of thyroid dysfunction was 36.03%, with subclinical hypothyroidism (26.5%) as the most common thyroid dysfunction. Thyroid dysfunction was much common in females (42.85%) compared to males (30.04%) (p = 0.008) and in type 1 diabetes (50%) compared to type 2 diabetes mellitus (35.41%) (p = 0.218). Diabetic patients with thyroid dysfunction had higher total cholesterol, HDL cholesterol, and LDL cholesterol in comparison to patients without thyroid dysfunction. Significant risk factors for thyroid dysfunction, specifically hypothyroidism (overt and subclinical), were smoking (relative risk of 2.56 with 95% CI (1.99-3.29, p < 0.001)), family history of thyroid disease (relative risk of 2.57 with 95% CI (2.0-3.31, p < 0.001)), and female gender (relative risk of 1.44 with 95% CI (1.09-1.91, p = 0.01)). Conclusions. Thyroid dysfunction is common among Nepalese diabetic patients. Smoking, family history of thyroid disease, and female gender are significantly associated with thyroid dysfunction.

    Large electronic healthcare databases have become an important worldwide data resource for drug safety research after approval. Signal generation methods and drug safety studies based on these data facilitate the prospective monitoring of drug safety after approval, as has been recently required by EU law and the German Medicines Act. Despite its large size, a single healthcare database may include insufficient patients for the study of a very small number of drug-exposed patients or the investigation of very rare drug risks. For that reason, in the United States, efforts have been made to work on models that provide the linkage of data from different electronic healthcare databases for monitoring the safety of medicines after authorization in (i) the Sentinel Initiative and (ii) the Observational Medical Outcomes Partnership (OMOP). In July 2014, the pilot project Mini-Sentinel included a total of 178 million people from 18 different US databases. The merging of the data is based on a distributed data network with a common data model. In the European Network of Centres for Pharmacoepidemiology and Pharmacovigilance (ENCEPP) there has been no comparable merging of data from different databases; however, first experiences have been gained in various EU drug safety projects. In Germany, the data of the statutory health insurance providers constitute the most important resource for establishing a large healthcare database. Their use for this purpose has so far been severely restricted by the Code of Social Law (Section 75, Book 10). Therefore, a reform of this section is absolutely necessary. PMID:26092163

    Objective To examine the benefits of early gestational diabetes mellitus (GDM) screening in a high-risk population. Study Design Retrospective cohort of all singletons diagnosed with GDM with indications for early screening: GDM or macrosomia in a prior pregnancy or obesity. Subjects were classified as early (<20 weeks) or routine (>24 weeks) screening. Patients diagnosed with GDM were managed according to standard institutional protocols. Outcomes examined were cesarean delivery (CD), preeclampsia, large for gestational age (LGA), small for gestational age (SGA), macrosomia, and preterm birth (PTB). Results Subjects screened early were more likely to have had GDM in a prior pregnancy, hypertension, higher body mass index, and higher fasting glucose. Early and routine screening groups had similar incidences of CD (adjusted odds ratio [AOR] 0.95, 95% confidence interval [CI] 0.55-1.64), preeclampsia (AOR 0.84, 95% CI 0.38-1.83), LGA (AOR 0.90, 95% CI 0.51-1.72), SGA (AOR 0.38, 95% CI 0.13-1.13), and macrosomia (AOR 1.00, 95% CI 0.53-1.87). Subjects in the early screening group had a higher incidence of PTB (AOR 1.79, 95% CI 1.08-2.99). Conclusion We did not detect a benefit to early screening for women who met the criteria. The utility of early GDM screening requires evaluation in a prospective trial. PMID:26890436

    Background A growing body of evidence supports the role of type 2 diabetes as an individual-level risk factor for tuberculosis (TB), though evidence from developing countries with the highest TB burdens is lacking. In developing countries, TB is most common among the poor, in whom diabetes may be less common. We assessed the relationship between individual-level risk, social determinants and population health in these settings. Methods We performed individual-level analyses using the World Health Survey (n = 124 607; 46 countries). We estimated the relationship between TB and diabetes, adjusting for gender, age, body mass index, education, housing quality, crowding and health insurance. We also performed a longitudinal country-level analysis using data on per-capita gross domestic product and TB prevalence and incidence and diabetes prevalence for 1990–95 and 2003–04 (163 countries) to estimate the relationship between increasing diabetes prevalence and TB, identifying countries at risk for disease interactions. Results In lower income countries, individuals with diabetes are more likely than non-diabetics to have TB [univariable odds ratio (OR): 2.39; 95% confidence interval (CI): 1.84–3.10; multivariable OR: 1.81; 95% CI: 1.37–2.39]. Increases in TB prevalence and incidence over time were more likely to occur when diabetes prevalence also increased (OR: 4.7; 95% CI: 1.0–22.5; OR: 8.6; 95% CI: 1.9–40.4). Large populations, prevalent TB and projected increases in diabetes make countries like India, Peru and the Russia Federation areas of particular concern. Conclusions Given the association between diabetes and TB and projected increases in diabetes worldwide, multi-disease health policies should be considered. PMID:21252210

    We studied genes involved in pancreatic β cell function and survival, identifying associations between SNPs in WFS1 and diabetes risk in UK populations that we replicated in an Ashkenazi population and in additional UK studies. In a pooled analysis comprising 9,533 cases and 11,389 controls, SNPs in WFS1 were strongly associated with diabetes risk. Rare mutations in WFS1 cause Wolfram syndrome; using a gene-centric approach, we show that variation in WFS1 also predisposes to common type 2 diabetes. PMID:17603484

    The metabolic syndrome has been shown to increase risk for cardiovascular disease and diabetes. The Atherosclerosis Risk in Communities study enrolled 15,792 middle-aged Americans in 4 communities in the United States and has followed them for the development of cardiovascular disease and diabetes. Several analyses from this large, biracial, population study have shown that the metabolic syndrome, as well as individual metabolic syndrome components, is predictive of the prevalence and incidence of coronary heart disease, ischemic stroke, carotid artery disease, and diabetes.

    Purpose To determine the prevalence of high-risk factors for hydroxychloroquine (HCQ) retinopathy and compliance with the American Academy of Ophthalmology (AAO) screening guidelines at the San Francisco Veterans Affairs Medical Center (VASF) and to develop an approach to improve the risk-benefit relationship and informed consent during HCQ treatment. Methods All medical records of patients receiving HCQ were reviewed, with special attention to high-risk factors for retinopathy. The results were used to develop a method of enhancing the risk-benefit relationship and improving informed consent at the VASF. Results Of the 109 patients taking HCQ at the VASF, 87% had at least one high-risk factor for retinal toxicity and 47% had two or more risk factors. Thirty-four percent had no evidence of an eye examination having been performed. An approach has been developed to improve the risk-benefit and informed consent for patients using HCQ at the VASF. Conclusions A significant number of veterans taking HCQ may be at an increased risk for retinal toxicity. More than one-third of these patients may not be managed as recommended by the AAO. Methods to minimize these risks and improve informed consent are outlined. PMID:18427609

  1. Severe hypoglycaemia in type 1 diabetes: impact of the renin-angiotensin system and other risk factors.

    PubMed

    2009-11-01

    Hypoglycaemia is an unavoidable side effect to insulin therapy of diabetes. In daily life some hypoglycaemic episodes are recognised by the patients and corrected by ingestion of glucose, but occasionally unrecognised episodes progress into severe hypoglycaemia with cognitive impairment and the need for assistance from other persons in order to manage the situation. Such episodes represent the most feared side effect to insulin treatment and are regarded as the major limiting factor for achievement of recommended glycaemic targets in type 1 diabetes. The series of studies that constitute this thesis was conducted to assess the significance of severe hypoglycaemia as a clinical problem in the type 1 diabetic population, to evaluate the impact of known risk factors on occurrence of severe hypoglycaemia, and to identify new markers that could contribute to improved prediction of, and inspire to novel preventive measures of, severe hypoglycaemia. Our studies confirm that severe hypoglycaemia is still a major clinical problem in type 1 diabetes. The individual susceptibility to severe hypoglycaemia is highly varying and conventional risk factors - with major contribution from hypoglycaemia unawareness - only account for a limited part of this variation. Results from a case-series suggest that the use of psychoactive substances may be as significant as alcohol for promotion of risk of severe hypoglycaemia - a finding which needs to be confirmed by case-control studies. We identified elevated renin-angiotensin system activity as a novel predictor of risk of severe hypoglycaemia in type 1 diabetes with potential clinical significance. Thus, three sequential renin-angiotensin system-related risk factors were associated with severe hypoglycaemia, and by including these factors in a common model both subjects at low and at high risk within a one-year period were identified. Preliminary data suggest that this is explained by impaired capability of subjects with high renin

    2015-01-01

    Patients with type II diabetes (T2DM) have an elevated risk for cardiovascular disease (CVD), and it is considered to be a leading cause of morbidity and premature mortality in these patients. Many traditional risk factors such as age, male sex, hypertension, dyslipidemia, glycemic control, diabetes duration, renal dysfunction, obesity, and smoking have been studied and identified as independent factors for CVD. Quantifying the risk of CVD among diabetics using the common risk factors in order to plan the treatment and preventive measures is important in the management of these patients as recommended by many clinical guidelines. Therefore, several risk assessment tools have been developed in different parts of the world for this purpose. These include the tools that have been developed for general populations and considered T2DM as a risk factor, and the tools that have been developed for T2DM populations specifically. However, due to the differences in sociodemographic factors and lifestyle patterns, as well as the differences in the distribution of various CVD risk factors in different diabetic populations, the external applicability of these tools on different populations is questionable. This review aims to address the applicability of the existing CVD risk models to the Omani diabetic population. PMID:26421110

    Type 2 diabetes represents a major health problem worldwide, with immigrants strongly contributing to the increase in diabetes in many countries. Norway is not immune to the process, and immigrants in the country are experiencing an increase in the prevalence of diabetes after arrival. However, the dynamics of these transitions in relation to the duration of residence in the new environment in Norway are not clearly understood. From this background, a cross-sectional quantitative study using a respondent-driven sampling method was conducted among 302 Somali women living in Oslo area. The results show that 41% of the study participants will be at risk for developing diabetes in the coming 10 years, which coincides with 85% of the study participants being abdominally obese. Significant associations were found between years of stay in Norway and the risk for diabetes with those who lived in Norway >10 years, having twofold higher odds of being at risk for developing diabetes compared to those who lived in Norway ≤5 years (OR: 2.16, CI: 1.08–4.32). Understanding the mechanisms through which exposure to the Norwegian environment leads to higher obesity and diabetes risk may aid in prevention efforts for the rapidly growing African immigrant population.

    Despite substantial progress in the study of diabetes, important questions remain about its comorbidities and clinical heterogeneity. To explore these issues, we develop a framework allowing for the first time to quantify nation-wide risks and their age- and sex-dependence for each diabetic comorbidity, and whether the association may be consequential or causal, in a sample of almost two million patients. This study is equivalent to nearly 40,000 single clinical measurements. We confirm the highly controversial relation of increased risk for Parkinson's disease in diabetics, using a 10 times larger cohort than previous studies on this relation. Detection of type 1 diabetes leads detection of depressions, whereas there is a strong comorbidity relation between type 2 diabetes and schizophrenia, suggesting similar pathogenic or medication-related mechanisms. We find significant sex differences in the progression of, for instance, sleep disorders and congestive heart failure in diabetic patients. Hypertension is a highly sex-sensitive comorbidity with females being at lower risk during fertile age, but at higher risk otherwise. These results may be useful to improve screening practices in the general population. Clinical management of diabetes must address age- and sex-dependence of multiple comorbid conditions.

    hydrates. Methane gas leaking into the marine environment is rapidly oxidized by microbes such that only a very small fraction of the methane emitted at the seabed escapes into the atmosphere. Slope failure is a more serious thread. It may lead to a complete destruction of seabed infrastructures for gas production and transport, significant gas emissions, and damage to local benthic ecosystems. New regulations should be developed at the national and international level to address and minimize the specific environmental risks associated with the future commercial exploitation of marine gas hydrates.

    INTRODUCTION This study aimed to determine the risk factors of diabetic Charcot arthropathy of the foot among diabetic patients with and without foot problems. METHODS This was a case-control study involving diabetic patients attending the Diabetic Foot Care and Wound Management Clinic at University Malaya Medical Centre, Kuala Lumpur, Malaysia, from June 2010 to June 2011. Data on sociodemographic profiles, foot factors and diabetes characteristics was collected and analysed. RESULTS A total of 48 diabetic patients with Charcot arthropathy of the foot were identified. Data from these 48 patients was compared with those of 52 diabetic patients without foot problems. Up to 83.3% of patients with diabetic Charcot arthropathy presented with unilateral Charcot foot, most commonly located at the midfoot (45.8%). Patients with a history of foot problems, including foot ulcer, amputation, surgery or a combination of problems, had the highest (26-time) likelihood of developing Charcot arthropathy (odds ratio 26.4; 95% confidence interval 6.4–109.6). Other significant risk factors included age below 60 years, more than ten years’ duration of diabetes mellitus and the presence of nephropathy. CONCLUSION A history of prior diabetic foot problems is the greatest risk factor for developing diabetic Charcot arthropathy, compared with other risk factors such as diabetes characteristics and sociodemographic profiles. Preventive management of diabetic foot problems in the primary care setting and multidisciplinary care are of paramount importance, especially among chronic diabetic patients. PMID:27075668

    In this study, the effect of phytic acid supplement on streptozotocin-induced diabetic rats was investigated. Diabetic rats were fed rodent chow with or without phytic acid supplementation for thirty days. Blood and organ samples were collected for assays. The average food intake was the highest and the body weight gain was the lowest in the group fed phytic acid supplement compared to the diabetic and normal control groups. There was a downward trend in intestinal amylase activity in the group fed phytic acid supplement compared to the other groups. The spike in random blood glucose was the lowest in the same group. We noted reduced serum triglycerides and increased total cholesterol and HDL cholesterol levels in the group fed phytic acid supplement. Serum alkaline phosphatase and alanine amino transferase activities were significantly (P < 0.05) increased by phytic acid supplementation. Systemic IL-1β level was significantly (P < 0.05) elevated in the diabetic control and supplement treated groups. The liver lipogenic enzyme activities were not significantly altered among the groups. These results suggest that phytic acid supplementation may be beneficial in the management of diabetes mellitus. The observed adverse effect on the liver may be due to the combined effect of streptozotocin-induced diabetes and phytic acid supplementation. PMID:24454345

    Background Prevalence of type 2 diabetes (T2D) is increasing worldwide. T2D prevention by lifestyle intervention is effective. Pragmatic scalable interventions are needed, with evidence to efficiently target and monitor such interventions. We report pooled analyses of data from three European trial cohorts: to analyse T2D incidence, sustained weight loss and utility of risk predictors. Methods We analysed data on 749 adults with impaired glucose tolerance (278 men and 471 women, mean age 56 years, mean BMI 31 kgm−2) recruited between 1993 and 2003, and randomised to intensive lifestyle intervention (I) or lifestyle advice control (C). The intervention aimed to increase physical activity, modify diet, and promote weight loss≥5%. Using Cox-regression survival analysis, we assessed T2D incidence and the impact on T2D incidence of sustained weight loss, and of baseline cut-point values of FINDRISC score, fasting plasma glucose (FPG), and HbA1c. Results Mean follow-up duration was 3.1 years. T2D was diagnosed in 139 participants (I = 45/379, C = 94/370). Cumulative T2D incidence was 57% lower in the intervention compared with the control group (HR 0.42 (95% CI 0.29 to 0.60) P<0.001). Participants with ≥5% weight loss at one year had 65% lower T2D incidence (HR 0.35 (95% CI 0.22 to 0.56) P<0.001); maintaining ≥5% weight loss for two and three years further reduced T2D incidence. Recommended cut-points to identify those at high risk for T2D would have identified different proportions of European Diabetes Prevention Study (EDIPS) participants with similar hazard-ratios for intervention effect. Conclusions Pooled analysis of EDIPS trial data reinforces evidence for T2D prevention by lifestyle intervention. Analysis showed the preventive effect of ≥5% weight loss, especially if maintained long term, which has utility for intervention monitoring. Analysis of proposed cut-points demonstrates difficulties in balancing risk and benefit, to efficiently target

    Importance Optimization of glycemic control is critical to reduce diabetes related complications, but long-term success is challenging. Although vision loss is among the greatest fears of individuals with diabetes, comprehensive personalized diabetes education and risk assessments are not consistently employed in ophthalmology settings. Objective To determine whether point-of-care measurement of HbA1c and personalized diabetes complication risk assessments performed during retinal ophthalmology visits improve glycemic control as assessed by HA1c. Design/Setting Ophthalmologist office based clinical trial where investigators from 42 sites were randomly assigned to provide either study-prescribed augmented diabetes assessment and education, or usual care. Participants Adults with type 1 or 2 diabetes enrolled into two cohorts: “more frequent” than annual follow-up (502 control and 488 intervention participants) and “annual” follow-up (368 and 388 participants). Intervention(s) Point-of-care measurement of HbA1c, blood pressure, and retinopathy severity; individualized estimate of retinopathy progression risk derived from the visit findings; structured comparison and review of past and current clinical findings; and structured education with immediate assessment and feedback regarding participant understanding. Intervention was performed at enrollment and routine ophthalmic follow-up visits scheduled at least 12 weeks apart. Main Outcome Measure(s) Mean change in HbA1c from baseline to 1 year. Secondary outcomes included body mass index, blood pressure, and diabetes self-management practices and attitudes surveys. Results In the “more frequent” cohort, mean (SD) change in HbA1c at 1 year was −0.1% (1.5%) in the control group and −0.3% (1.4%) in the intervention group (adjusted mean difference −0.09%, 95% confidence interval −0.29% to +0.12%, P=0.35). In the “annual” cohort, mean (SD) change in HBA1c was 0.0% (1.1%) and −0.1% (1

    Diabetic and new-onset diabetic patients with hypertension have higher cardiac morbidity than patients without diabetes. We aimed to investigate whether baseline predictors of cardiac morbidity, the major constituent of the primary endpoint in the Valsartan Antihypertensive Long-term Use Evaluation (VALUE) trial, were different in patients with diabetes and new-onset diabetes compared to patients without diabetes. In total, 15,245 high-risk hypertensive patients in the VALUE trial were followed for an average of 4.2 years. At baseline, 5250 patients were diabetic by the 1999 World Health Organization criteria, 1298 patients developed new-onset diabetes and 8697 patients stayed non-diabetic during follow-up. Cardiac morbidity was defined as a composite of myocardial infarction and heart failure requiring hospitalization, and baseline predictors were identified by univariate and multivariate stepwise Cox regression analyses. History of coronary heart disease (CHD) and age were the most important predictors of cardiac morbidity in both diabetic and non-diabetic patients. History of CHD, history of stroke and age were the only significant predictors of cardiac morbidity in patients with new-onset diabetes. Predictors of cardiac morbidity, in particular history of CHD and age, were essentially the same in high-risk hypertensive patients with diabetes, new-onset diabetes and without diabetes who participated in the VALUE trial.

    2004-06-01

    Genetically modified (GM) crops have met with widespread approval among scientists and policy makers in the United States, but public approval of GM crops, both domestically and abroad, is progressing much more slowly. An underlying cause of public wariness may be that both nations and individual consumers do not perceive significant benefits to themselves from GM crops, while fearing the risks they may incur. In this study, an economic analysis is conducted to determine whether the benefits of one type of GM corn, Bt corn (genetically modified to resist damage from the ECB and Southwestern corn borer), outweigh the potential risks; and who the "winners" and "losers" are among stakeholder groups that may be affected by Bt corn. It is found that Bt corn growers, consumers, and industry all benefit from Bt corn adoption, though the purported health and environmental benefits of reducing chemical pesticide usage through Bt corn are negligible. Though the aggregated public benefit is large, the welfare gain to individual consumers is small and may not make up for perceived risks. While environmental and health risks of Bt corn are unlikely, the potential market risks-impacting both the organic corn market and total U.S. corn exports-are found to be significant. Currently, distributional analysis is not a part of regulatory decision making of Bt corn in the United States; yet it may help to explain why decision makers at both the government and individual-consumer levels have failed to embrace Bt corn and other GM crops.

    Relatively small lifestyle modifications related to weight reduction, physical activity and diet has been shown to decrease the risk of type 2 diabetes. Connected with diet, low consumption of meat has been suggested as a protective factor of diabetes. The aim was to examine the association between the consumption of total meat or the specific types of meat and risk of type 2 diabetes. The ATBC cohort included middle aged male smokers. During up to 12 years of follow-up, 1098 incident cases of diabetes were diagnosed from 24,845 participants through the nationwide register. Food consumption was assessed by a validated food frequency questionnaire. In the age and intervention group adjusted model, high total meat consumption was a risk factor of type 2 diabetes (relative risk (RR) 1.50, 95% confidence interval (CI): 1.23, 1.82, highest vs. lowest quintile). The result was similar after adjustment for environmental factors and foods related to diabetes and meat consumption. The RR of type 2 diabetes was 1.37 for processed meat (95% CI: 1.11, 1.71) in the multivariate model. The results were explained more by intakes of sodium than intakes of saturated fatty acids, protein, cholesterol, heme iron, magnesium and nitrate, and were not modified by obesity. No association was found between red meat, poultry and the risk of type 2 diabetes. In conclusion, it may help to prevent the global epidemic of type 2 diabetes by reducing the consumption of processed meat. It seems that sodium of processed meat may explain the association.

    Background The EQ-5D was used to compare burden experienced by respondents with diabetes and those at risk for diabetes. Methods A survey including the EQ-5D was mailed to individuals with self-reported diabetes, as well as those without diabetes but with the following risk factors (RFs): (1) abdominal obesity, (2) body mass index ≥ 28 kg/m2, (3) dyslipidemia, (4) hypertension, and (5) cardiovascular disease. Non-diabetes respondents were combined into 0–2 RFs and 3–5 RFs. Mean EQ-5D scores were compared across groups using analysis of variance. Multivariable linear regression modeling identified factors affecting respondents' EQ-5D scores. Results Complete responses were available from >75% of each cohort. Mean EQ-5D index scores were significantly lower for respondents with type 2 diabetes and 3–5 RFs (0.778 and 0.792, respectively) than for those with 0–2 RFs (0.870, p < 0.001 for each); score for respondents with type 2 diabetes was also significantly lower than for those with 3–5 RFs (p < 0.001). Similar patterns were seen for visual analog scale (VAS). For both VAS and index scores, after adjusting for other characteristics, respondents reported decreasing EQ-5D scores as status moved from low to high risk (-6.49 for VAS score and -0.045 for index score) to a diagnosis of type 2 diabetes (-9.75 for VAS score and -0.054 for index score; p < 0.001 vs. 0–2 RFs for all). Conclusion High-risk and type 2 diabetes groups had similar EQ-5D scores, and both were substantially lower than in low-risk respondents. PMID:18304340

    This is a period of ever-tightening defense budgets and continuing pressure on the public sector to be more commercial-like, Property policies, practices, and regulations are increasingly being challenged and changed. In these times, we must be leaders in understanding and defining the value of our profession from a commercial standpoint so that we can provide the right services to our customers and explain and defend the value of those services. To do so, we must step outside current property management practices, regulations, and oversight. We must learn to think and speak in the language of those who fund us--a financial language of risk, cost, and benefit. Regardless of regulation and oversight, our bosses are demanding that we demonstrate (financially) the benefits of current practice, or else. This article is intended to be the beginning of an effort to understand and define our profession in terms of risk, cost, and benefit so that we can meet these new challenges. The first step in this effort must be defining and measuring risk, cost, and benefit. Our costs, although sometimes difficult to capture, are easy to understand: they are almost exclusively the effort, both within and without the property management organization, involved in managing property. Unfortunately, property risks and benefits are not so simple or so well understood. Generally, risks and benefits are identified and measured through physical inventory results: potential and actual shortages. This paper will explore the weaknesses in the current understanding and use of shortage information as the yardstick for property management risks and performance. It will define a new framework for understanding the purpose and value of property management. And finally, it will set a course for a new method of measuring and valuing physical inventoty shortages. This new method will yield accurate and useful measures of property management risk and benefit. Once risk and benefit are accurately

    We present a new approach to population health, in which data-driven predictive models are learned for outcomes such as type 2 diabetes. Our approach enables risk assessment from readily available electronic claims data on large populations, without additional screening cost. Proposed model uncovers early and late-stage risk factors. Using administrative claims, pharmacy records, healthcare utilization, and laboratory results of 4.1 million individuals between 2005 and 2009, an initial set of 42,000 variables were derived that together describe the full health status and history of every individual. Machine learning was then used to methodically enhance predictive variable set and fit models predicting onset of type 2 diabetes in 2009-2011, 2010-2012, and 2011-2013. We compared the enhanced model with a parsimonious model consisting of known diabetes risk factors in a real-world environment, where missing values are common and prevalent. Furthermore, we analyzed novel and known risk factors emerging from the model at different age groups at different stages before the onset. Parsimonious model using 21 classic diabetes risk factors resulted in area under ROC curve (AUC) of 0.75 for diabetes prediction within a 2-year window following the baseline. The enhanced model increased the AUC to 0.80, with about 900 variables selected as predictive (p < 0.0001 for differences between AUCs). Similar improvements were observed for models predicting diabetes onset 1-3 years and 2-4 years after baseline. The enhanced model improved positive predictive value by at least 50% and identified novel surrogate risk factors for type 2 diabetes, such as chronic liver disease (odds ratio [OR] 3.71), high alanine aminotransferase (OR 2.26), esophageal reflux (OR 1.85), and history of acute bronchitis (OR 1.45). Liver risk factors emerge later in the process of diabetes development compared with obesity-related factors such as hypertension and high hemoglobin A1c. In conclusion

    OBJECTIVE To examine the BMI-stratified associations between diabetes and the risks of all-cause death, cardiovascular disease (CVD) death, and cancer death. RESEARCH DESIGN AND METHODS Using a prospective study with 12 rural Japanese general populations (n = 3,641, mean age, 53.7 years; 33.5% men), we examined the associations between diabetes and the risk of all-cause death, CVD death, and cancer death. We also examined the effects of BMI and age on such associations. RESULTS During an average duration of 10.2 years (37,278 person-years), 240 deaths occurred (54 deaths from CVD, 101 from cancer, and 85 from other causes). Cox regression analysis showed leanness (defined as the lowest quartile of entire BMI; mean, 19.5 kg/m2), but not obesity (BMI ≥25 kg/m2), and diabetes were independently associated with an increased risk of all-cause death (hazard ratio [HR] 1.70 and 1.65, respectively; both P < 0.01.). Stratification with cause-specific deaths showed that leanness and obesity were associated with CVD death (HR 3.77 and 2.94, respectively), whereas diabetes was associated with cancer death (HR 1.87; all P < 0.05). The increased risk of all-cause death in diabetes was substantially higher in lean subjects aged <65 years (HR 3.4) or those aged ≥65 years (HR 4.2), whereas the risk in obese diabetes patients was significant only in subjects aged <65 years (HR 2.32; all P < 0.05). CONCLUSIONS Among the Japanese general population, diabetes confers an increased risk of all-cause death. Particular attention must be paid to the pronounced high mortality in diabetes accompanied with leanness, regardless of age. PMID:23250802

    Objectives To determine whether a less invasive approach to aortic valve replacement (AVR) improves clinical outcomes in diabetic patients with aortic stenosis (AS). Background Diabetes is associated with increased morbidity and mortality after surgical AVR for AS. Methods Among treated patients with severe symptomatic AS at high-risk for surgery in the PARTNER trial, we examined outcomes stratified by diabetes status of patients randomly assigned to transcatheter or surgical AVR. The primary outcome was all-cause mortality at 1 year. Results Among 657 patients enrolled in PARTNER who underwent treatment, there were 275 patients with diabetes (145 transcatheter, 130 surgical). There was a significant interaction between diabetes and treatment group for 1-year all-cause mortality (p=0.048). Among diabetic patients, all-cause mortality at 1 year was 18.0% in the transcatheter group and 27.4% in the surgical group (HR 0.60; 95% CI, 0.36–0.99; p=0.04). Results were consistent among patients treated via transfemoral or transapical routes. In contrast, among non-diabetic patients, there was no significant difference in all-cause mortality at 1 year (p=0.48). Among diabetic patients, the 1-year rates of stroke were similar between treatment groups (3.5% transcatheter vs. 3.5% surgery, p=0.88), but the rates of renal failure requiring dialysis >30 days were lower in the transcatheter group (0% vs. 6.1%, p=0.003). Conclusions Among patients with diabetes and severe symptomatic AS at high-risk for surgery, this post-hoc stratified analysis of the PARTNER trial suggests there is a survival benefit, no increase in stroke, and less renal failure from treatment with transcatheter compared to surgical AVR.

    This paper is focused on summarizing the "lessons learned" from discussions at the 2010 NCRP Annual Meeting on effective communications on the subject of radiation benefits and risks in public exposures. Five main lessons learned are discussed in regard to effective methods of public communication: the use of new social media communication tools such as Facebook and Twitter, emergency situations that require rapid societal and personal messaging, medical radiological procedures where benefits must be described in comparison to long-term health risks of radiation exposures, and information that should be provided to stakeholders in situations such as environmental radionuclide contamination to which members of the public may be exposed. It is concluded that effective communications in which radiation benefits are contrasted with health risks of exposure are an important aspect of making and implementing decisions on employing radiation health protection procedures.

    Evidence supports the benefits of fish consumption during pregnancy, primarily because of the effects of n-3 polyunsaturated fatty acids on the neurodevelopment of the fetus. Many fish may also be potent sources of methylmercury and polychlorinated biphenol exposure, which have been shown to have severe negative impacts on both the mother and fetus. Therefore, all women of childbearing age should be informed of both the benefits and risks of fish consumption. PMID:18586185

    Background and aims Co-existing major depression was found to have a negative impact on the diabetes outcome and the quality of life. The aim of the present study was to assess the prevalence of depressive symptoms in Romanian diabetes patients and to identify the risk factors associated with depression. Methods A total of 144 type 2 diabetes patients were included in the study. Five models of presumed predictors were used to assess the risk factors for depressive symptoms, using hierarchical regression analysis. Together with demographics, disease, lifestyle predictors, previous depressive symptoms and diabetes distress were taken into account. Results In our sample the prevalence of depression was 12.6%. Main risk factors for depressive symptoms were previous depressive symptoms which were associated with depression in both Model 4 (β=0.297, p=0.013) and Model 5 (β=0.239, p=0.017) and diabetes distress in Model 5 (β=0.540, p≤0.001). Employment (β =−0.276, p=0.029) and increased number of diabetes complications (β=0.236, p=0.017) became significant when diabetes distress was added to the analysis. Conclusions The overall prevalence of depressive symptoms was found to be in range with the prevalence identified in the literature. Previous depression and diabetes distress were both independently associated with depression, confirming the bidirectional relationship between depression and diabetes distress. Due to the consequences for daily living, screening for diabetes distress and depression should be done in primary care units both by physicians and trained nurses. PMID:27547056

    The prevalence of diabetes in Jordan has been increasing. The early diagnosis of diabetes is vital to slow its progression. The Arab Risk (ARABRISK) screening tool is a self-administered questionnaire used to determine people who are at high risk for developing diabetes. This study aimed to identify people at high risk for developing type 2 diabetes by using the ARABRISK in the capital of Jordan.A cross-sectional study was conducted with a convenience sample of people in the capital of Jordan. The ARABRISK screening tool was administered to identify the participants' risk for developing diabetes. In addition to descriptive statistics, percentages of the ARABRISK categories were represented, and an independent samples t test was used to explore the differences between men and women. A total of 513 participants with a mean age of 51.94 (SD = 10.33) were recruited; 64.9% of the participants were men (n = 333).The total ARABRISK score ranged from 0 to 25 with a mean score of 12.30 (SD = 4.76). Using the independent samples t test, women (mean = 13.25, SE = 0.10) had significantly higher ARABRISK total scores than men did (mean = 12.95, SE = 0.09), t(141) = -2.23, P = 0.03 in the "moderate risk" category. All of the items in the ARABRISK questionnaire were found to be good predictors of the ARABRISK total scores. Among them, age, body mass index (BMI), and high blood glucose (HBG) were the best predictors as indicated by the standardized regression coefficient (β). Older age, obesity, elevated weight circumference, absence of daily physical activity, daily consumption of fruits/vegetables, presence of high blood pressure (HBP), and HBG were significantly associated with increased odds of high ARABRISK total scores. Neither a history of gestational diabetes nor a positive family history was associated with an increased odds of high ARABRISK total scores.By identifying risk factors in these participants, interventions and lifestyle

    With one person dying from diabetes-related preventable complications, including foot complications, every 7 seconds across the world, it is clear this is a major health challenge. Foot ulceration in diabetes remains the commonest reason for hospital admission in Western countries. From neuropathy to peripheral vascular disease, the challenges are significant and can result in premature death, but early diagnosis by aware health-care professionals, combined with supporting people in self-care, can help reduce the problems of diabetes to manageable proportions.

    Objective To assess the relation between adherence to a Mediterranean diet and the incidence of diabetes among initially healthy participants. Design Prospective cohort study with estimates of relative risk adjusted for sex, age, years of university education, total energy intake, body mass index, physical activity, sedentary habits, smoking, family history of diabetes, and personal history of hypertension. Setting Spanish university department. Participants 13 380 Spanish university graduates without diabetes at baseline followed up for a median of 4.4 years. Main outcome measures Dietary habits assessed at baseline with a validated 136 item food frequency questionnaire and scored on a nine point index. New cases of diabetes confirmed through medical reports and an additional detailed questionnaire posted to those who self reported a new diagnosis of diabetes by a doctor during follow-up. Confirmed cases of type 2 diabetes. Results Participants who adhered closely to a Mediterranean diet had a lower risk of diabetes. The incidence rate ratios adjusted for sex and age were 0.41 (95% confidence interval 0.19 to 0.87) for those with moderate adherence (score 3-6) and 0.17 (0.04 to 0.75) for those with the highest adherence (score 7-9) compared with those with low adherence (score <3). In the fully adjusted analyses the results were similar. A two point increase in the score was associated with a 35% relative reduction in the risk of diabetes (incidence rate ratio 0.65, 0.44 to 0.95), with a significant inverse linear trend (P=0.04) in the multivariate analysis. Conclusion Adherence to a Mediterranean diet is associated with a reduced risk of diabetes. PMID:18511765

    In 2008, clinical observations in our colony of sooty mangabeys (Cercocebus atys) suggested a high frequency of type 2 diabetes. Postmortem studies of diabetic animals revealed dense amyloid deposits in pancreatic islets. To investigate these findings, we screened our colony (97 male mangabeys; 99 female mangabeys) for the disease from 2008 to 2012. The overall prevalence of diabetes was 11% and of prediabetes was 7%, which is nearly double that reported for other primate species (less than 6%). Fructosamine and triglyceride levels were the best indicators of diabetes; total cholesterol and glycated hemoglobin were not associated with disease. Increasing age was a significant risk factor: prevalence increased from 0% in infants, juveniles, and young adults to 11% in adults and 19% in geriatric mangabeys. Sex, medroxyprogesterone acetate exposure, and SIV status were unrelated to disease. Weight was marginally higher in prediabetics, but body condition did not indicate obesity. Of the 49 mangabeys that were necropsied after clinical euthanasia or death from natural causes, 22 were diabetic; all 22 animals demonstrated pancreatic amyloid, and most had more than 75% of islets replaced with amyloid. We conclude that type 2 diabetes is more common in mangabeys than in other primate species. Diabetes in mangabeys has some unusual pathologic characteristics, including the absence of altered cholesterol levels and glycated hemoglobin but a robust association of pancreatic insular amyloidosis with clinical diabetes. Future research will examine the genetic basis of mangabey diabetes and evaluate additional diagnostic tools using imaging and serum markers. PMID:24956212

    Although increased urinary albumin excretion may increase the risk of adverse renal outcomes in patients with diabetes, it remains unclear whether microalbuminuria is associated with a higher incidence of macroalbuminuria in the absence of non-diabetic kidney events that frequently develop during the long-term course of type 2 diabetes. This historical cohort study included patients with type 2 diabetes, spot urine albumin:creatinine ratio (ACR) <300 mg/gCr and normal serum creatinine concentrations treated between August 1988 and April 2015. Patients with any evidence suggesting non-diabetic kidney diseases at baseline were excluded. Over a median follow-up of 50 months, 70 of the 1760 included patients developed macroalbuminuria. Twenty-one of these patients were diagnosed with non-diabetic renal events. The five-year cumulative incidence of macroalbuminuria in patients with ACRs of 0–7.5 mg/gCr, 7.5–30 mg/gCr, 30–150 mg/gCr, and 150–300 mg/gCr were 0%, 0.53%, 3.5%, and 36.0%, respectively, with significant differences between each pair of ACR categories. In type 2 diabetes, higher urinary ACR, even within a level of normoalbuminuria, was associated with a greater incidence of macroalbuminuria when non-diabetic renal events were excluded. These results conflict with findings suggesting that microalbuminuria is a poor indicator for the progression of diabetic nephropathy. PMID:27210499

  8. Incident Diabetes and Mobility Limitations: Reducing Bias Through Risk-set Matching

    PubMed Central

    2015-01-01

    Background. Increased prevalence of diabetes in the U.S. population could contribute substantially to increases in disability at older ages. Previous studies have examined the association between prevalent diabetes and various impairments and disabilities. Methods considering incident, rather than prevalent, diabetes as the exposure of interest can reduce bias in estimates of these associations. Methods. Risk-set matching, a type of propensity score matching meant to handle time-varying exposures, was used to estimate the relationship between incident diabetes and mobility limitations among adults in the Health and Retirement Study. This approach ensures that covariates precede diabetes onset rather than follow it. Results. Individuals who were diagnosed with diabetes during the study period accumulated more subsequent mobility limitations than were accumulated by matched controls. Among observationally similar pairs of individuals, those who developed diabetes reported an average of 24.9% more mobility limitations at study exit than those who did not. Conclusions. The magnitude of the relationship between diabetes and limitations estimated in this article is smaller than that presented in previous studies, but the method presented here is likely to provide a less-biased estimate of the association between diabetes and accumulation of mobility limitations.

  10. Costs and benefits of river flood risk management at the global scale

    2015-12-01

    Floods cause billions of dollars of economic damage each year, and this is expected to increase in the future due to socioeconomic development and climate change‎. To limit these losses, and to protect people and their livelihoods from flooding, adaptation in flood risk management systems is required that takes into account both current and future risk. Whilst several global scale flood risk models have now been developed to assess both current and future river flood risk, to date none of these include currently installed or future flood risk management measures, nor their costs and benefits. In this contribution, a new modelling framework is presented for assessing both the costs and benefits of flood risk management at the global scale, which employs a cascade of models to provide first-cut estimates of the costs and benefits of adaptation by means of hazard reduction through the construction of dikes. The modeling framework is first used to assess what protection standards would be required in the future per state, in order to keep future flood risk constant at today's levels, and the costs and benefits associated with such a strategy. In a second analysis, flood risk protection standards are calculated per state that optimize the net present value of adaptation. The potential usefulness and limitations of the results for practical applications are discussed, as well as key avenues for future developments. In particular, recent research has shown flood risk itself to be non-stationary, being influenced by oscillations in climate variability caused by phenomenon such as El Niño Southern Oscillation (ENSO). The results of the research will be discussed within the context of climate-driven ENSO variability.

  11. Diabetes Drugs and Cardiovascular Safety

    PubMed Central

    2016-01-01

    Diabetes is a well-known risk factor of cardiovascular morbidity and mortality, and the beneficial effect of improved glycemic control on cardiovascular complications has been well established. However, the rosiglitazone experience aroused awareness of potential cardiovascular risk associated with diabetes drugs and prompted the U.S. Food and Drug Administration to issue new guidelines about cardiovascular risk. Through postmarketing cardiovascular safety trials, some drugs demonstrated cardiovascular benefits, while some antidiabetic drugs raised concern about a possible increased cardiovascular risk associated with drug use. With the development of new classes of drugs, treatment options became wider and the complexity of glycemic management in type 2 diabetes has increased. When choosing the appropriate treatment strategy for patients with type 2 diabetes at high cardiovascular risk, not only the glucose-lowering effects, but also overall benefits and risks for cardiovascular disease should be taken into consideration.

    This manuscript assesses the risks, benefits, and ethical concerns regarding the use of assisted reproductive techniques (ART) to create a new donor for stem cell transplantation. We address ethical literature, the medical and psychosocial impact on patient, donor, family, and medical caregivers, and the appropriate decision-making process. We conclude that the use of ART to create a stem cell donor can be ethically acceptable. The decision to conceive a donor has medical and psychosocial implications. The family is the appropriate decision-maker and must consider risks and benefits to all parties with input from medical caregivers. PMID:16917911

  13. Intrauterine diabetic environment confers risks for type 2 diabetes mellitus and obesity in the offspring, in addition to genetic susceptibility.

    2001-01-01

    Numerous studies have reported that offspring whose mothers had type 2 diabetes mellitus (DM) are more likely to develop type 2 DM, impaired glucose tolerance, and obesity at an early age than offspring whose fathers had DM. Exposure to the diabetic intrauterine environment has been shown to be an important risk factor for all these conditions. To what extent transmission of type 2 DM from mother to offspring is the effect of genetic inheritance and to what extent it is the long-term consequence of exposure to maternal hyperglycemia is still uncertain. There are, of course, interactions between the diabetic intrauterine environment and genetics. Several data in experimental animals as well as in humans suggest, however, that exposure of the fetus to the mother's DM confers a risk for type 2 DM and obesity that is above any genetically transmitted susceptibility. In the Pima Indian population much of the increase in childhood type 2 DM can be attributed to the diabetic intrauterine environment. This suggests that intensive glucose control during pregnancy might have extended beneficial effects, contributing to a decrease in the prevalence of childhood type 2 DM. PMID:11592564

  17. A semi-quantitative approach to GMO risk-benefit analysis.

    PubMed

    Morris, E Jane

    2011-10-01

    In many countries there are increasing calls for the benefits of genetically modified organisms (GMOs) to be considered as well as the risks, and for a risk-benefit analysis to form an integral part of GMO regulatory frameworks. This trend represents a shift away from the strict emphasis on risks, which is encapsulated in the Precautionary Principle that forms the basis for the Cartagena Protocol on Biosafety, and which is reflected in the national legislation of many countries. The introduction of risk-benefit analysis of GMOs would be facilitated if clear methodologies were available to support the analysis. Up to now, methodologies for risk-benefit analysis that would be applicable to the introduction of GMOs have not been well defined. This paper describes a relatively simple semi-quantitative methodology that could be easily applied as a decision support tool, giving particular consideration to the needs of regulators in developing countries where there are limited resources and experience. The application of the methodology is demonstrated using the release of an insect resistant maize variety in South Africa as a case study. The applicability of the method in the South African regulatory system is also discussed, as an example of what might be involved in introducing changes into an existing regulatory process.

  18. What are the chances? Evaluating risk and benefit information in consumer health materials

    PubMed Central

    Burkell, Jacquelyn

    2004-01-01

    Much consumer health information addresses issues of disease risk or treatment risks and benefits, addressing questions such as “How effective is this treatment?” or “What is the likelihood that this test will give a false positive result?” Insofar as it addresses outcome likelihood, this information is essentially quantitative in nature, which is of critical importance, because quantitative information tends to be difficult to understand and therefore inaccessible to consumers. Information professionals typically examine reading level to determine the accessibility of consumer health information, but this measure does not adequately reflect the difficulty of quantitative information, including materials addressing issues of risk and benefit. As a result, different methods must be used to evaluate this type of consumer health material. There are no standard guidelines or assessment tools for this task, but research in cognitive psychology provides insight into the best ways to present risk and benefit information to promote understanding and minimize interpretation bias. This paper offers an interdisciplinary bridge that brings these results to the attention of information professionals, who can then use them to evaluate consumer health materials addressing risks and benefits.

    A substantial body of evidence suggests that an abnormal intra-uterine milieu elicited by maternal metabolic disturbances as diverse as malnutrition, placental insufficiency, diabetes and obesity may be able to programme susceptibility of the foetus to later develop chronic degenerative diseases such as obesity, hypertension, cardiovascular diseases and type 2 diabetes (T2D). As insulin-producing cells have been placed centre stage in the development of T2D, this review examines developmental programming of the beta-cell mass (BCM) in various rodent models of maternal protein restriction, calorie restriction, overnutrition and diabetes. The main message is that whatever the initial maternal insult (F0 generation) and whether alone or in combination, it gives rise to the same programmed BCM outcome in the daughter generation (F1). The altered BCM phenotype in F1 females prohibits normal BCM adaptation during pregnancy and, thus, diabetes (gestational diabetes) ensues. This gestational diabetes is then passed from one generation (F1) to the next (F2, F3 and so on). This review highlights a number of studies that have identified epigenetic mechanisms that may contribute to altered BCM development and beta-cell failure, as observed in diabetes. In addition to their role in instilling the programmed defect, these non-genomic mechanisms may also be involved in its intergenerational transmission. PMID:24948417

    Hip fracture, which is associated with substantial morbidity and long-term mortality, imposes a major burden on the healthcare system. Diabetes is a risk factor for osteoporosis, which is a crucial risk factor of hip fracture. However, epidemiological studies investigating the risk of hip fracture among patients with type 2 diabetes are limited. This study explored the association between hemoglobin A1c (HbA1c) and the risk of hip fracture in people with type 2 diabetes aged 65 years and older. We conducted a retrospective cohort study of 20,025 older patients with type 2 diabetes who participated in the National Diabetes Case Management Program in Taiwan. The HbA1c level at the baseline and hip fracture incidence over an average of 7.41 years of follow-up were analyzed (maximum and standard deviation were 10.9 and 2.42 years, respectively). A total of 1514 hip fracture cases were recorded. The incidence rates of hip fracture were 9.15, 8.02, 9.58, 10.61, 12.51, and 13.43 per 1000 person-years in patients with baseline HbA1c levels of < 6%, 6-7%, 7%-8%, 8%-9%, 9%-10%, and ≥ 10%, respectively. After multivariate adjustment, the risk of hip fracture increased among patients with HbA1c levels of 9%-10% and ≥ 10.0% compared with patients with HbA1c levels of 6-7% (hazard ratio, 1.24; 95% confidence interval, 1.02-1.49 and 1.32; 1.09-1.58, respectively). Significant linear trends among various HbA1c levels were observed (P  < 0.05). Patients with type 2 diabetes whose HbA1c levels exceeded 9.0% exhibited an increased risk of hip fracture, confirming a linear relationship. Our study's findings demonstrated the importance of glycemic control for fracture prevention in older adults with type 2 diabetes. PMID:25598134

    Mefloquine is an antimalarial drug that has been commonly used in military settings since its development by the US military in the late 1980s. Owing to the drug's neuropsychiatric contraindications and its high rate of inducing neuropsychiatric symptoms, which are contraindications to the drug's continued use, the routine prescribing of mefloquine in military settings may be problematic. Due to these considerations and to recent concerns of chronic and potentially permanent psychiatric and neurological sequelae arising from drug toxicity, military prescribing of mefloquine has recently decreased. In settings where mefloquine remains available, policies governing prescribing should reflect risk-benefit decision-making informed by the drug's perceived benefits and by consideration both of the risks identified in the drug's labeling and of specific military risks associated with its use. In this review, these risks are identified and recommendations are made for the rational prescribing of the drug in light of current evidence. PMID:26579231

    Aging is associated with body composition changes that lead to glucose intolerance and increased risk of diabetes. The incidence of diabetes increases with aging, and the prevalence has increased because of the increased life expectancy of the population. Lifestyle modifications through nutrition and exercise in combination with medications are the main components of diabetes management. The potential benefits of nutrition and exercise intervention in older people with diabetes are enormous. Nutrition and exercise training are feasible even in frail older people living in care homes and should take into consideration individual circumstances, cultural factors, and ethnic preferences.

    The incidence of sternal wound infections (SWI) after coronary artery bypass surgery (CABG) as reported worldwide is low. However, it is associated with significant increase of postoperative mortality and treatment costs. The major risk factors discussed are diabetes mellitus and bilateral IMA harvesting of the internal mammary artery. This study analyses data of 590 patients receiving CABG concerning the risk factors for SWI. Sternal wound infections occur significantly more often in diabetic patients, one crucial and significant additional risk factor is obesity. PMID:27547690

    A cross sectional descriptive study was carried out to determine the prevalence and risk factors of diabetes mellitus among adults in Jaffna District. Multistage stratified cluster sampling technique was employed to select 544 participants. An interviewer administrated questionnaire was used. Anthropometric and blood pressure (BP) measurements were recorded and biochemical parameters were analysed. Response rate was 95.3%. Of them, 224 (43.8%) were male. The prevalence of diabetes mellitus was 16.4% (95% CI: 13.3- 19.9); in males 19.6% (95% CI: 14.6-25.4) and in females 13.9% (95% CI: 10.1-18.5). Of the diabetics, 27.4% were previously undiagnosed. In the final multivariable model, participants with family history of diabetes were 3.5 times (p<0.001) more likely and those with high waist hip ratio were 2 times (p=0.009) more likely to develop diabetes mellitus.

    Research in developed countries showed that many citizens perceive that radio signals transmitted by mobile phones and base stations represent potential health risks. Less research has been conducted in developing countries focused on citizen perceptions of risks and benefits, despite the recent and rapid introduction of mobile communication technologies. This study aims to identify factors that are influential in determining the tradeoffs that Bangladeshi citizens make between risks and benefits in terms of mobile phone technology acceptance and health concerns associated with the technology. Bangladesh was selected as representative of many developing countries inasmuch as terrestrial telephone infrastructure is insubstantial, and mobile phone use has expanded rapidly over the last decade, even among the poor. Issues of importance were identified in a small-scale qualitative study among Bangladeshi citizens (n = 13), followed by a survey within a sample of Bangladeshi citizens (n = 500). The results demonstrate that, in general, the perceived benefits of mobile phone technology outweigh the risks. The perceived benefits are primarily related to the social and personal advantages of mobile phone use, including the ability to receive emergency news about floods, cyclones, and other natural disasters. Base stations were seen as a symbol of societal advance. The results furthermore suggest that overall risk perceptions are relatively low, in particular health risks, and are primarily driven by perceptions that related to crime and social inconvenience. Perceived health risks are relatively small. These findings show that risk communication and management may be particularly effective when contextual factors of the society where the system is implemented are taken into consideration.

    OBJECTIVE Patients with type 2 diabetes mellitus (T2DM) underestimate their risk of developing severe complications, and they do not always understand the risk communication by their caregivers. The aim of this study was to investigate the effects of an intervention focused on the communication of the absolute 10-year risk of developing cardiovascular disease (CVD) in patients with T2DM. RESEARCH DESIGN AND METHODS A randomized controlled trial was performed in T2DM patients newly referred to the Diabetes Care System (DCS) West-Friesland, a managed-care system in the Netherlands. The intervention group (n = 131) received a six-step CVD risk communication. Control subjects (n = 130) received standard managed care. The primary outcome measure was appropriateness of risk perception (difference between actual CVD risk calculated by the UK Prospective Diabetes Study risk engine and risk perception). Secondary outcome measures were illness perceptions, attitude and intention to change behavior, satisfaction with the communication, and anxiety and worry about CVD risk. Patients completed questionnaires at baseline, at 2 weeks (immediately after the intervention), and at 12 weeks. RESULTS Appropriateness of risk perception improved between the intervention and control groups at 2 weeks. This effect disappeared at 12 weeks. No effects were found on illness perceptions, attitude and intention to change behavior, or anxiety and worry about CVD risk. Patients in the intervention group were significantly more satisfied with the communication. CONCLUSIONS This risk communication method improved patients’ risk perception at 2 weeks but not at 12 weeks. Negative effects were not found, as patients did not become anxious or worried after the CVD risk communication. PMID:22923669

    Objective Diabetes mellitus is associated with increased fracture risk in women but few studies are available in men. To evaluate the relationship between diabetes and prospective non-vertebral fractures in elderly men, we used data from the Osteoporotic Fractures in Men (MrOS) study. Research Design and Methods MrOS enrolled 5,994 men (≥65 years). Diabetes (ascertained by self-report, use of diabetes medication or elevated fasting glucose) was reported in 881 subjects of whom 80 used insulin. Hip and spine bone mineral density (BMD) were measured with dual x-ray absorptiometry. After recruitment, men were followed for incident nonvertebral fracture with a tri-annual questionnaire for an average of 9.1 (SD 2.7) years. The Cox proportional hazards model was used to assess incident risk of fractures. Results In models adjusted for age, race, clinic site and total hip BMD, the risk of non-vertebral fracture was higher in men with diabetes, compared with normoglycemic men, [hazard ratio (HR) 1.30 (95% CI: 1.09–1.54)] and was elevated in men using insulin (HR 2.46; 95% CI 1.69–3.59). Men with impaired fasting glucose did not have a higher risk of fracture compared to normoglycemic men (HR 1.04; 95% CI 0.89–1.21). After multivariable adjustment, the risk of non-vertebral fracture remained higher only among men with diabetes who were using insulin (HR 1.74; 95% CI 1.13–2.69). Conclusions Men with diabetes who are using insulin have an increased risk of non-vertebral fracture for a given age and BMD. PMID:24908567

    Aim Dietary patterns have been associated with type 2 diabetes incidence, but little is known about the impact of ethnicity on this relation. This study evaluated the association of four a priori dietary quality indexes and type 2 diabetes risk among whites, Japanese Americans, and Native Hawaiians in the Hawaii component of the Multiethnic Cohort (MEC). Methods After excluding participants with prevalent diabetes and missing values, the analysis included 89,185 participants (11,217 cases). Dietary intake was assessed at baseline with a quantitative food frequency questionnaire designed for use in the relevant ethnic populations. Sex- and ethnicity-specific hazard ratios were calculated for the Healthy Eating Index-2010 (HEI-2010), the alternative HEI-2010 (AHEI-2010), the alternate Mediterranean diet score (aMED), and the Dietary Approaches to Stop Hypertension (DASH). Results We observed significant inverse associations between higher scores of the DASH index and type 2 diabetes risk in white men and women, as well as in Japanese American women and Native Hawaiian men with respective risk reductions of 37, 31, 19 and 21% (highest compared to lowest index category). A higher adherence to the AHEI-2010 and aMED diet was related to a 13–28% lower type 2 diabetes risk in white participants but not in other ethnic groups. No significant associations with type 2 diabetes risk were observed for the HEI-2010 index. Conclusions The small ethnic differences in type 2 diabetes risk associated with scores of a priori-defined dietary patterns may be due to different consumption patterns of food components and the fact that the original indexes were not based on Asians and Pacific Islanders.

    Objective Weight dissatisfaction, defined as discordance between actual and goal weight, may be associated with increased risk for several obesity-related comorbidities. The purpose of the study was to examine the association between weight dissatisfaction and risk of developing type 2 diabetes. Methods This longitudinal study used data from 9,584 adults enrolled in the Aerobics Center Longitudinal Study with an average of 5.1±4.1 years of follow-up. Key variables included multiple measures of measured weight, self-reported goal weight, and incident diabetes. Weight dissatisfaction was defined as being above the median of measured weight minus goal weight. Cox proportional hazards regression estimated hazard ratios (HR) and 95% confidence intervals (95%CI) for diabetes incidence by weight dissatisfaction. Results HRs for time-until-diabetes diagnosis revealed that family history of diabetes (HR=1.46, 95%CI=1.13-1.90), age (HR=1.03, 95%CI=1.02-1.04), and weight dissatisfaction (HR=1.83, 95%CI=1.50-2.25) at baseline were statistically significant predictors. Longitudinally, higher risk was observed in individuals who either stayed dissatisfied (HR=2.98, 95%CI=1.98-4.48) or became dissatisfied (HR=1.51, 95%CI=0.79-2.89), compared to those who either stayed satisfied (HR=1.00, referent) or became satisfied (HR=0.98, 95%CI=0.46-2.10). After additional adjustment for BMI, the elevated HR for those who remained dissatisfied compared to those who remained satisfied persisted (HR=2.85, 95%CI=1.89-4.31). Conclusions Chronic weight dissatisfaction increased type 2 diabetes risk. Weight dissatisfaction, regardless of BMI, represents a potentially important psychophysiological modifier of the relationships between BMI and risk of type 2 diabetes and warrants greater attention in future studies of chronic disease risk.

    OBJECTIVE Consumption of sugar-sweetened beverages (SSBs), which include soft drinks, fruit drinks, iced tea, and energy and vitamin water drinks has risen across the globe. Regular consumption of SSBs has been associated with weight gain and risk of overweight and obesity, but the role of SSBs in the development of related chronic metabolic diseases, such as metabolic syndrome and type 2 diabetes, has not been quantitatively reviewed. RESEARCH DESIGN AND METHODS We searched the MEDLINE database up to May 2010 for prospective cohort studies of SSB intake and risk of metabolic syndrome and type 2 diabetes. We identified 11 studies (three for metabolic syndrome and eight for type 2 diabetes) for inclusion in a random-effects meta-analysis comparing SSB intake in the highest to lowest quantiles in relation to risk of metabolic syndrome and type 2 diabetes. RESULTS Based on data from these studies, including 310,819 participants and 15,043 cases of type 2 diabetes, individuals in the highest quantile of SSB intake (most often 1–2 servings/day) had a 26% greater risk of developing type 2 diabetes than those in the lowest quantile (none or <1 serving/month) (relative risk [RR] 1.26 [95% CI 1.12–1.41]). Among studies evaluating metabolic syndrome, including 19,431 participants and 5,803 cases, the pooled RR was 1.20 [1.02–1.42]. CONCLUSIONS In addition to weight gain, higher consumption of SSBs is associated with development of metabolic syndrome and type 2 diabetes. These data provide empirical evidence that intake of SSBs should be limited to reduce obesity-related risk of chronic metabolic diseases. PMID:20693348

    Higher body mass index (BMI) is a well-established risk factor for type 2 diabetes, and rates of obesity and type 2 diabetes are substantially higher among Mexican-Americans relative to non-Hispanic European Americans. Mexican-Americans are genetically diverse, with a highly variable distribution of Native American, European, and African ancestries. Here, we evaluate the role of Native American ancestry on BMI and diabetes risk in a well-defined Mexican-American population. Participants were randomly selected among individuals residing in the Houston area who are enrolled in the Mexican-American Cohort study. Using a custom Illumina GoldenGate Panel, we genotyped DNA from 4,662 cohort participants for 87 Ancestry-Informative Markers. On average, the participants were of 50.2% Native American ancestry, 42.7% European ancestry and 7.1% African ancestry. Using multivariate linear regression, we found BMI and Native American ancestry were inversely correlated; individuals with <20% Native American ancestry were 2.5 times more likely to be severely obese compared to those with >80% Native American ancestry. Furthermore, we demonstrated an interaction between BMI and Native American ancestry in diabetes risk among women; Native American ancestry was a strong risk factor for diabetes only among overweight and obese women (OR = 1.190 for each 10% increase in Native American ancestry). This study offers new insight into the complex relationship between obesity, genetic ancestry, and their respective effects on diabetes risk. Findings from this study may improve the diabetes risk prediction among Mexican-American individuals thereby facilitating targeted prevention strategies. PMID:26501420

    In the early 2000s, the prevalence of diabetes in adults aged ≥30 years in Korea was about 9% to 10%, and it remained stable. However, a nationwide survey showed that this prevalence increased over the past few years. After age-standardization using the Korean population of the year 2010, the prevalence of diabetes in adults aged ≥30 years was 10.0% to 10.8% between 2001 and 2012, which increased to 12.5% in 2013 and 11.6% in 2014. During that period, there have been changes in the gender- and age-specific prevalence of diabetes in Korean adults. The prevalence of diabetes in the elderly population increased significantly, while this prevalence in young adults, especially in young women, did not change significantly. The contribution of each diabetic risk factor, such as obesity, β-cell dysfunction, sarcopenia, and socioeconomic status, in developing diabetes has also changed during that period in each gender and age group. For young women, obesity was the most important risk factor; by contrast, for elderly diabetic patients, sarcopenia was more important than obesity as a risk factor. Considering the economic burden of diabetes and its associated comorbidities, a public health policy targeting the major risk factors in each population might be more effective in preventing diabetes.

    Background The impact of long working hours on diabetes is controversial; however, shift work is known to increase the risk of diabetes. This study aimed to investigate the association between long working hours and diabetes among civil servants in Japan separately by shift work schedules. Methods A prospective cohort study was conducted from April 2003 to March 2009. A total of 3195 men aged ≥35 years who underwent an annual health checkup at baseline were analyzed by shift work schedules (2371 non-shift workers and 824 shift workers). Self-reported working hours were categorized as 35–44 and ≥45 hours per week. The incidence of diabetes was confirmed by fasting plasma glucose concentration ≥126 mg/dL and/or self-reported medical diagnosis of diabetes at the annual checkup. A Cox proportional model was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for developing diabetes associated with long working hours. Results The median follow-up period of non-shift and shift workers was 5.0 and 4.9 years, respectively. During this period, 138 non-shift workers and 46 shift workers developed diabetes. A decreased HR was found among non-shift workers working ≥45 hours per week (HR 0.84; 95% CI, 0.57–1.24); however, shift workers working ≥45 hours per week had a significantly increased risk of diabetes (HR 2.43; 95% CI, 1.21–5.10) compared with those working 35–44 hours per week. An analysis restricted to non-clerical workers also showed similar results. Conclusions The risk of diabetes associated with long working hours differed by shift work schedules. PMID:27001115

    Children with Multiple Risk Factor Exposition Benefit from the German "Strengthening Families Program" The German adaptation of the substance use-preventive family-based Strengthening Families Program 10-14 (SFP, Iowa version) was evaluated in a longitudinal two-year follow-up trial. Participants were N = 292 children with a mean age of twelve years at baseline, and N = 292 parents. We employed a multi-centric, randomized-controlled, two-armed (SFP vs. minimal control condition) study design. Following a "risk moderation hypothesis", we assumed that children with an elevated risk-exposition R(+) would benefit more than children with a low risk-exposition R(-) irrespective of the preventive intervention, and that R(+) under SFP would benefit more than R(+) under the minimal control condition. "Risk-exposition" was measured in correspondence with the Communities That Care Youth Survey-questionnaire. A total of 28 % of children were classified with an elevated risk level. Children's reports confirmed our hypothesis: R(+) report a total of eleven improvements, four of these being significantly more distinct than in the other groups (Anxiety-Depressivity, Punitive Parenting of mother, Punitive Parenting of father, Unbalanced family functioning). In three measures an improvement appears solely in R(+) under SFP (Satisfaction with family functioning, School Attachment and Peer Relationship Quality, Quality of Life). Parents' reports showed a similar tendency, but were less pronounced. PMID:27595812

    A growing body of research links child abuse and neglect to a range of negative short- and long-term health outcomes. Determining a child's risk of maltreatment at or shortly after birth provides an opportunity for the delivery of targeted prevention services. This study presents findings from a predictive risk model (PRM) developed to estimate the likelihood of substantiated maltreatment among children enrolled in New Zealand's public benefit system. The objective was to explore the potential use of administrative data for targeting prevention and early intervention services to children and families. A data set of integrated public benefit and child protection records for children born in New Zealand between January 1, 2003, and June 1, 2006, was used to develop a risk algorithm using stepwise probit modeling. Data were analyzed in 2012. The final model included 132 variables and produced an area under the receiver operating characteristic curve of 76%. Among children in the top decile of risk, 47.8% had been substantiated for maltreatment by age 5 years. Of all children substantiated for maltreatment by age 5 years, 83% had been enrolled in the public benefit system before age 2 years. This analysis demonstrates that PRMs can be used to generate risk scores for substantiated maltreatment. Although a PRM cannot replace more-comprehensive clinical assessments of abuse and neglect risk, this approach provides a simple and cost-effective method of targeting early prevention services.

    The aim of this study was to identify and quantify risk factors for amputation in diabetic patients hospitalized for foot infections. This cross-sectional study comprised 100 patients with diabetic infectious complications in the lower limbs. The variables investigated were related to diabetes, infection, and treatment compliance. Multiple Cox regression analysis was performed to identify the variables independently associated with the outcome of amputation. The most prevalent chronic complications were neuropathy and hypertension. Most patients presented with a neuroischemic foot (86%). The Morisky test showed that 72% were not compliant with diabetes treatment. Regarding patient outcome, 61% progressed to amputation, 14% to debridement, and 9% to revascularization. The results showed a 42% higher risk for progression to amputation in patients with previous use of antimicrobials. Also, the amputation risk was 26% higher for those less compliant with diabetes treatment. An increase of one point in the Wagner ulcer classification criteria corresponded to a 65% increase in the risk of amputation. Undergoing conservative, nonsurgical procedures prior to admission provided a 63% reduction in the risk of amputation. Knowledge of these factors is critical to enable multidisciplinary teams to develop treatment plans for these patients so as to prevent the need for amputation. PMID:26998493

    In a case-control study of 169 preeclamptics and 201 controls, we assessed maternal parental history of chronic hypertension and diabetes in relation to preeclampsia risk among Peruvian women. Participants provided information on parental history of the two conditions and other covariates during postpartum interviews. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) adjusted for confounding by age, parity and prepregnancy adiposity. In this population, women were more likely to know the diabetes status of their parents than their hypertension status. Compared with women without a parental history of hypertension, women with a parental history of hypertension experienced a 20% increased risk of preeclampsia (OR = 1.2; 95% CI 0.7-2.2) that did not reach statistical significance. Women with a positive parental history for diabetes had a 3.4-fold increased risk of preeclampsia (95% CI 1.4-8.4). Women with a positive parental history of both hypertension and diabetes, as compared with those whose parents had neither condition, experienced a 4.6- fold increased risk of preeclampsia (OR = 4.6; 95% CI 0.9-23.0). Our results are generally consistent with the thesis that parental history of hypertension and diabetes reflects genetic and behavioral factors whereby women may be predisposed to an increased risk of preeclampsia.

    SGLT2 inhibitors represent a novel therapeutic approach for the tretment of type 2 diabetes mellitus. Beyond glucose control, these drugs also induce weight loss and blod pressure reduction. In a specific cardiovascular outcome trial (EMPA-REG-OUTCOME), the SGLT 2 inhibitor empagliflozin has for the first time demonstrated to reduce cardiovascular and overall mortality as well as hospitalization for heart failure in patients with type 2 diabetes and high cardiovascular risk. These results will drastically affect future recommendations for the treatment of type 2 diabetes mellitus.). PMID:27176455

    Background: Hypoglycemia mitigation is critical for appropriately managing patients with diabetes. Advanced technologies are becoming more prevalent in diabetes management, but their benefits have been primarily judged on the basis of hemoglobin A1c. A critical appraisal of the effectiveness and limitations of advanced technologies in reducing both A1c and hypoglycemia rates has not been previously performed. Methods: The cost of hypoglycemia was estimated using literature rates of hypoglycemia events resulting in hospitalizations. A literature search was conducted on the effect on A1c and hypoglycemia of advanced technologies. The cost-effectiveness of continuous subcutaneous insulin infusion (CSII) and real-time continuous glucose monitors (RT-CGM) was reviewed. Results: Severe hypoglycemia in insulin-using patients with diabetes costs $4.9-$12.7 billion. CSII reduces A1c in some but not all studies. CSII improves hypoglycemia in patients with high baseline rates. Bolus calculators improve A1c and improve the fear of hypoglycemia but not hypoglycemia rates. RT-CGM alone and when combined with CSII improve A1c with a neutral effect on hypoglycemia rates. Low-glucose threshold suspend systems reduce hypoglycemia with a neutral effect on A1c, and low-glucose predictive suspend systems reduce hypoglycemia with a small increase in plasma glucose levels. In short-term studies, artificial pancreas systems reduce both hypoglycemia rates and plasma glucose levels. CSII and RT-CGM are cost-effective technologies, but their wide adoption is limited by cost, psychosocial, and educational factors. Conclusions: Most currently available technologies improve A1c with a neutral or improved rate of hypoglycemia. Advanced technologies appear to be cost-effective in diabetes management, especially when including the underlying cost of hypoglycemia. PMID:25555391

    Quantitative patient preferences are a method to involve patients in regulatory benefit-risk assessment. Assuming preferences can be elicited, there might be multiple advantages to their use. Legal, methodological and procedural issues do however imply that preferences are currently at most part of the solution on how to best involve patients in regulatory decision making. Progress is recently made on these issues.

    The EU project BRAFO proposed a framework for risk-benefit assessment of foods, or changes in diet, that present both potential risks and potential benefits to consumers (Hoekstra et al., 2012a). In higher tiers of the BRAFO framework, risks and benefits are integrated quantitatively to estimate net health impact measured in DALYs or QALYs (disability- or quality-adjusted life years). This paper describes a general model that was developed by a second EU project, Qalibra, to assist users in conducting these assessments. Its flexible design makes it applicable to a wide range of dietary questions involving different nutrients, contaminants and health effects. Account can be taken of variation between consumers in their diets and also other characteristics relevant to the estimation of risk and benefit, such as body weight, gender and age. Uncertainty in any input parameter may be quantified probabilistically, using probability distributions, or deterministically by repeating the assessment with alternative assumptions. Uncertainties that are not quantified should be evaluated qualitatively. Outputs produced by the model are illustrated using results from a simple assessment of fish consumption. More detailed case studies on oily fish and phytosterols are presented in companion papers. The model can be accessed as web-based software at www.qalibra.eu. PMID:23261673

    This study integrated risk-benefit analysis with prospect theory with the overall objective of identifying the type of management behavior represented by farmers' choices of mastitis control options (MCOs). Two exploratory factor analyses, based on 163 and 175 Swedish farmers, respectively, highlighted attitudes to MCOs related to: (1) grouping cows and applying milking order to prevent spread of existing infection and (2) working in a precautionary way to prevent mastitis occurring. This was interpreted as being based on (1) reactive management behavior on detection of udder-health problems in individual cows and (2) proactive management behavior to prevent mastitis developing. Farmers' assessments of these MCOs were found to be based on asymmetrical evaluations of risks and benefits, suggesting that farmers' management behavior depends on their individual reference point. In particular, attitudes to MCOs related to grouping cows and applying milking order to prevent the spread of mastitis once infected cows were detected were stronger in the risk domain than in the benefit domain, in accordance with loss aversion. In contrast, attitudes to MCOs related to working in a precautionary way to prevent cows from becoming infected in the first place were stronger in the benefit domain than in the risk domain, in accordance with reverse loss aversion. These findings are of practical importance for farmers and agribusiness and in public health protection work to reduce the current extensive use of antibiotics in dairy herds. PMID:24372180

    Maternal influenza vaccination prevents influenza illness in both mothers and newborns. Results from some recent studies have suggested that influenza vaccination might also prevent adverse pregnancy outcomes, such as preterm birth. However, it is challenging to conduct epidemiologic studies to evaluate the benefits to the fetus of maternal influenza vaccination because the causal benefit of vaccination is likely only experienced by the small fraction of the cohort in whom influenza illness is prevented by vaccination. The plausibility of detecting true differences in risks between groups under such conditions is rarely discussed. We aimed to inform the interpretation of studies in which the fetal benefits of maternal influenza vaccination are evaluated by estimating detectable risk ratios and necessary sample sizes for different study scenarios. Estimates of rates of influenza illness, vaccine effectiveness, vaccine uptake, and preterm birth and of the association of influenza illness with preterm birth were identified from the published literature. We calculated detectable risk ratios for preterm birth in vaccinated versus unvaccinated women and the associated sample size requirements. Our results demonstrated that under most scenarios, plausible differences between groups will be extremely challenging to detect (risk ratios for preterm birth of 0.9 to 1.0) and will require sample sizes infeasible for prospective epidemiologic research. This suggests that the large fetal benefits from influenza vaccination observed in epidemiologic studies are unlikely to be causal. PMID:27365363

    Several studies have now reported associations between gestational diabetes mellitus (GDM) and low free thyroxine (fT4) during the second and third trimesters, but not in the first trimester. The present study further examines relationships between low fT4, maternal weight, and GDM among women in the FaSTER (First and Second Trimester Evaluation of Risk) trial, in an effort to determine the extent to which thyroid hormones might contribute to causality. The FaSTER cohort includes 9351 singleton, euthyroid women; 272 of these women were subsequently classified as having GDM. Thyrotropin (TSH), fT4, and thyroid antibodies were measured at 11–14 weeks’ gestation (first trimester) and 15–18.9 weeks’ gestation (second trimester). An earlier report of this cohort documented an inverse relationship between fT4 in the second trimester and maternal weight. In the current analysis, women with GDM were significantly older (32 vs. 28 years) and weighed more (75 vs. 64.5 kg). Maternal weight and age (but not TSH) were significantly associated univariately with fT4 (dependent variable), in the order listed. Second trimester fT4 odds ratios (OR) for GDM were 2.06 [95% CI 1.37–3.09] (unadjusted); and 1.89 [95% CI 1.26–2.84] (adjusted). First trimester odds ratios were not significant: OR 1.45 [95%CI 0.97–2.16] (unadjusted) and 1.11 [95% CI 0.74–1.62] (adjusted). The second trimester fT4/GDM relationship thus appeared to strengthen as gestation progressed. In FaSTER, high maternal weight was associated with both low fT4 and a higher GDM rate in the second trimester. Peripheral deiodinase activity is known to increase with high caloric intake (represented by high weight). We speculate that weight-related low fT4 (the metabolically inactive prohormone) is a marker for deiodinase activity, serving as a substrate for conversion of fT4 to free triiodothyronine (fT3), the active hormone responsible for glucose-related metabolic activity.

    It has recently been suggested that the low-frequency c.136-14_136-13insC variant in high-mobility group A1 (HMGA1) may strongly contribute to insulin resistance and type 2 diabetes risk. In our study, we attempted to confirm that HMGA1 is a novel type 2 diabetes locus in French Caucasians. The gene was sequenced in 368 type 2 diabetic case subjects with a family history of type 2 diabetes and 372 normoglycemic control subjects without a family history of type 2 diabetes. None of the 41 genetic variations identified were associated with type 2 diabetes. The lack of association between the c.136-14_136-13insC variant and type 2 diabetes was confirmed in an independent French group of 4,538 case subjects and 4,015 control subjects and in a large meta-analysis of 16,605 case subjects and 46,179 control subjects. Finally, this variant had no effects on metabolic traits and was not involved in variations of HMGA1 and insulin receptor (INSR) expressions. The c.136-14_136-13insC variant was not associated with type 2 diabetes in individuals of European descent. Our study emphasizes the need to analyze a large number of subjects to reliably assess the association of low-frequency variants with the disease. PMID:22210315

    Background The prevalence of gastroparesis in type 2 diabetes mellitus (T2DM) vary widely. Our aim is to estimate the prevalence of clinical symptoms of gastroparesis among patients with type 2 diabetes mellitus and explore the relationship between gastroparesis and other risk factors. Methods A cross-sectional study evaluating 147 type 2 diabetics using the Gastroparesis Cardinal Symptoms Index (GCSI). A GCSI Total Score ≥ 1.90 were chosen as having definite symptoms of gastroparesis. All patients completed a demographic questionnaire and interviewed to complete the. Demographic Data, disease duration, Medication, comorbidities, recent blood glucose and HbA1C were collected and investigated. Results The prevalence of clinical symptoms of gastroparesis among type 2 diabetics was 10.8%. Clinical symptoms of gastroparesis were significantly correlated to HbA1c (p=0.001), blood glucose (p= 0.003), duration of diabetes (p= 0.02) and comorbidities (p=0.009). The most common symptoms were bloating, stomach fullness and early satiety (63.94%, 55.1% and 48.3% respectively). In logistic regression analysis, female gender emerged as significant independent predictors of the presence of at least one symptom. Conclusions The prevalence of clinical symptoms of gastroparesis observed in the Saudi patientsdiagnosedwithtype2 diabetes was 10.8% and is independently associated with poor controlled diabetes, hyperglycemia, and long duration of diabetes and history of Co-morbid conditions.

    The interrelation between diabetes mellitus and inflammatory periodontal disease has been intensively studied for more than 50 years, a real bidirectional influence existing between patient's glycemic level disorder and periodontal territories alteration. Several studies developed in this direction emerged to the evidences that reveal a general increase of prevalence, extent and severity of gingivitis and periodontitis. Inflammation plays an important role in this interrelation, orchestrating both the periodontal disease and diabetes mellitus pathogeny and complications. Conversely, periodontal disease--infectious disease characterized by a significant inflammatory component--can seriously impair metabolic control of some diabetic patient. Moreover, treatment of periodontal disease and reduction of oral signs of inflammation may have a beneficial result on the diabetic condition (1). Less clear are the mechanisms governing this interrelation (even the literature is abundant in this direction), and, very probably, periodontal diseases serve as initiators of insulin resistance (in a way similar to obesity), thereby aggravating glycemic control. Further research is so imposed in order to clarify this aspect of the relationship between diabetes and periodontal disease. PMID:18293711

    Objective Pre-pregnancy over-weight and excess weight gain during pregnancy have each been associated with an increased risk of delivering large babies. However, previous studies have focused on the separate effects of these two indices of weight in diabetic women. Method This study analyzed both separate and combined effects of pre-pregnant body mass index and weight gain in relation to macrosomia (≥ 4000g) in offspring among 815 non-diabetic women, using data collected from a retrospective study. Result Compared to mothers with normal pre-pregnancy BMI and pregnancy weight gain, risk of macrosomia in offspring was significantly elevated only in over-weight women with excess weight gain (adjusted OR =2.6, 95%CI [1.2,5.4]) but not among normal weight mothers with excess gain (adjusted OR=1.1, 95%CI [0.5,2.4]) or overweight mothers with normal or low gain (adjusted OR=1.1, 95%CI [0.4,3.1]). Conclusion Given the complications that are associated with delivering large babies, overweight women may benefit from not gaining excess weight gain in pregnancy. Synopsis Mothers who are overweight when entering pregnancy and also gain excess weight during pregnancy have a 2.5-fold increased risk of delivering a macrosomic baby. PMID:17376448

    Although regular physical activity is encouraged for individuals with diabetes, exercise at high altitude increases risk for a number of potential complications. This review highlights our current understanding of the key physiological and clinical issues that accompany high-altitude travel and proposes basic clinical strategies to help overcome obstacles faced by trekkers with Type 1 or Type 2 diabetes. Although individuals with diabetes have adaptations to the hypoxia of high altitude (increased ventilation, heart rate, blood pressure and hormonal responses), elevated counter-regulatory hormones can impair glycaemic control, particularly if mountain sickness occurs. Moreover, high-altitude-induced anorexia and increased energy expenditure can predispose individuals to dysglycaemia unless careful adjustments in medication are performed. Frequent blood glucose monitoring is imperative, and results must be interpreted with caution because capillary blood glucose meter results may be less accurate at high elevations and low temperatures. It is also important to undergo pre-travel screening to rule out possible contraindications owing to chronic diabetes complications and make well-informed decisions about risks. Despite the risks, healthy, physically fit and well-prepared individuals with Type 1 or Type 2 diabetes who are capable of advanced self-management can be encouraged to participate in these activities and attain their summit goals. Moreover, trekking at high altitude can serve as an effective means to engage in physical activity and to increase confidence with fundamental diabetes self-management skills. PMID:25962798

    Diabetes mellitus and hyperglycaemia are both independent risk factors (RF) for cardiovascular (CV) events and increased general and CV mortality. Type 2 diabetes, which is often associated with obesity, hypertension and dyslipidaemia, is accompanied by an up to fourfold increase in the incidence of acute coronary heart disease compared to normoglycaemia, even when other CV RF are equal. In the diabetic population, acute CV events are more likely to have associated cardiac complications, such as heart failure, and CV mortality is increased by twofold–fourfold. Several patients, hospitalised in medical, cardiology and intensive care departments, have undiagnosed diabetes mellitus or elevated glucose levels at the time of admission. These conditions require intensive care in the acute phase and dedicated follow-up at discharge. The Trialogue Plus project was created with the goal of providing good clinical practice guidelines and recommendations for the management of CV risk in patients with diabetes/hyperglycaemia at discharge from hospital. The aim is developing a document that defines timing, diagnostics, targets and therapeutic strategy for the management of CV risk, both in primary and in secondary prevention of patients with diabetes/hyperglycaemia who have experienced an event, involving the Diabetologist, Cardiologist, Internist, GP and area Specialists. This document concerns the implementation of existing guidelines and consensus statements, and as such, the recommendations have not been classified on the basis of scientific evidence and strength.

    Diabetes mellitus is a chronic metabolic disease which affects more and more people. It is estimated that in Poland it affects about 2.6 million people, of which diagnosed and treated diabetes constitute only 60% cases. The increased incidences of diabetes and prediabetes, indicate the need for undertake prevention activities and forces for continuous analysis of lifestyle factors that may influence the risk of developing the disease. In the thesis it was described in detail the relationship between liquids intake such as coffee, tea, pure water and sugar-sweetened beverages and risk of the occurrence of type 2 diabetes. Much research proved that coffee reduces the risk of developing diabetes. An inverse relationship has been demonstrated in the case of consumption of sugar-sweetened beverages. In relation to tea and pure water due to the limited amount of data, there is a need to further research conducting, however, there are some evidence that people who consumed less than 0.5 liters of water a day should be covered by preventive treatment against diabetes.

    Aim Three urinary biomarkers, kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), and cystatin C, have been suggested as clinically relevant highly specific biomarkers of acute kidney tubular damage. Yet, the utility of these biomarkers in the prognostication of diabetic nephropathy has been less studied. Therefore, we aimed to investigate the longitudinal association between these urinary biomarkers and cardiovascular mortality in patients with diabetes. Methods The study sample consisted of participants with diabetes in the community-based Uppsala Longitudinal Study of Adult Men (n = 91; mean age 77.8 years). During follow-up (median 8.3 years, interval 0.7–13.4 years), 33 participants died of cardiovascular causes. Results In a multivariable Cox regression model adjusting for age, glomerular filtration rate, and urinary albumin/creatinine ratio, higher urinary KIM-1/creatinine was associated with an increased risk for cardiovascular mortality (HR per SD increase 1.51, 95% confidence intervals 1.03–2.24, P = 0.03). Neither urinary NGAL/creatinine nor urinary cystatin C/creatinine were independently associated with an increased cardiovascular mortality risk. Conclusion In elderly men with diabetes, higher urinary KIM-1/creatinine was associated with an increased long-term risk of cardiovascular mortality independently of established markers of diabetic nephropathy. Our data provide support for kidney tubular damage as an important aspect of diabetic nephropathy that merits further investigation. PMID:27321055

Cox proportional hazards analysis was performed to estimate hazard ratios (HRs) for all-cause and cardiovascular mortality, while adjusting for CVD-related, diabetes-related, and nutritional factors. Results During a median follow-up of 9.2 y, 791 deaths were recorded, 306 due to CVD. Dietary fiber was inversely associated with all-cause mortality risk (adjusted HR per SD increase, 0.83 [95% CI, 0.75–0.91]) and CVD mortality risk (0.76[0.64–0.89]). No significant associations were observed for glycemic load, glycemic index, carbohydrate, sugar, or starch. Glycemic load (1.42[1.07–1.88]), carbohydrate (1.67[1.18–2.37]) and sugar intake (1.53[1.12–2.09]) were associated with an increased total mortality risk among normal weight individuals (BMI≤25 kg/m2; 22% of study population) but not among overweight individuals (P interaction≤0.04). These associations became stronger after exclusion of energy misreporters. Conclusions High fiber intake was associated with a decreased mortality risk. High glycemic load, carbohydrate and sugar intake were associated with an increased mortality risk in normal weight individuals with diabetes. PMID:22927948

    Assumptions about the economics of making a system safe are usually not explicitly stated in industrial and software models of safety-critical systems. These assumptions span a wide spectrum of economic tradeoffs with respect to resources expended to make a system safe. The missing component in these models that is necessary for capturing the effect of economic tradeoffs is risk. A qualitative risk-based software safety model is proposed that combines features of industrial and software systems safety models. The risk-based model provides decision makers with a basis for performing cost-benefit analyses of software safety-related activities.

  12. Multiple benefits of targeting inflammation in the treatment of type 2 diabetes.

    2016-04-01

    The association between the metabolic syndrome and a pathological activation of the innate immune system is now well established. Thus, defective insulin secretion and action are due, at least in part, to islet, liver and fat inflammation in type 2 diabetes. Furthermore, an inflammatory process also seems to be involved in the development of cardiovascular, renal and ophthalmological complications of this disease. Interestingly, several other inflammatory diseases are associated with the metabolic syndrome, such as psoriasis, gout and rheumatic arthritis. The aim of this review is to discuss the clinical progress of anti-inflammatory drugs in the treatment of type 2 diabetes and then speculate on the possible further development of these drugs, with the aim of using the drugs in combination in order to combat the multiple manifestations of inflammatory diseases. This review summarises a presentation given at the 'Islet inflammation in type 2 diabetes' symposium at the 2015 annual meeting of the EASD. It is accompanied by two other reviews on topics from this symposium (by Simone Baltrusch, DOI: 10.1007/s00125-016-3891-x , and Jerry Nadler and colleagues, DOI: 10.1007/s00125-016-3890-y ) and a commentary by the Session Chair, Piero Marchetti (DOI: 10.1007/s00125-016-3875-x ).

    Increased urinary albumin excretion (UAE) is a marker of renal and cardiovascular risk in patients with type 2 diabetes (DT2). What about the obese patient with DT2? Does albuminuria predict the progression of renal disease and/or cardiovascular disease? The objective of this study is to determine the link between albuminuria, renal risk and cardiovascular risk in a cohort of obese DT2 patients. This is a prospective study begun in September 2006. It included DT2 patients presenting obesity defined by a body mass index (BMI)>30 Kg/m(2). Three groups of patients were defined: normo-albuminuria (Urinary Albumin Excretion UAE<30 mg/day or Albumin Creatinine Ratio ACR<30 mg/g), micro-albuminuria (UAE=30-300 mg/day or ACR=30-300 mg/g) and macro-albuminuria (UAE>300 mg/day or ACR>300 mg/g). Data on 144 obese DT2 patients were compiled: The mean age of our patients was 59 ± 9 years and the sex ratio 0.26. The incidence of ESRD was higher in the macro-albuminuria group than in the two other groups (26.5% vs. 1.2%, p<0.001). The incidence of cardiovascular events was 15.4%, 14.3% and 23.5% in the normo, micro and macro-albuminuria groups (p=0.48). A history of cardiovascular comorbidities was the main cardiovascular risk in multivariate analysis (0R=15.07; 95% CI=5.30-42.82; p<0.001) and the low admission GFR (0R=5.67; 95% CI=1.23-9.77; p=0.008) was the main factor for progression of kidney disease in multivariate analysis. Albuminuria may be a better marker of kidney disease progression than of cardiovascular risk in the obese DT2 patient, according to our results. However, to accurately demonstrate the link albuminuria - renal risk and albuminuria - cardiovascular risk in the obese DT2 patient, additional studies using very strict criteria of selection and judgment are needed.

    This is a review of hypnotic drug risks and benefits, reassessing and updating advice presented to the Commissioner of the Food and Drug Administration (United States FDA). Almost every month, new information appears about the risks of hypnotics (sleeping pills). This review includes new information on the growing USA overdose epidemic, eight new epidemiologic studies of hypnotics’ mortality not available for previous compilations, and new emphasis on risks of short-term hypnotic prescription. The most important risks of hypnotics include excess mortality, especially overdose deaths, quiet deaths at night, infections, cancer, depression and suicide, automobile crashes, falls, and other accidents, and hypnotic-withdrawal insomnia. The short-term use of one-two prescriptions is associated with greater risk per dose than long-term use. Hypnotics are usually prescribed without approved indication, most often with specific contraindications, but even when indicated, there is little or no benefit. The recommended doses objectively increase sleep little if at all, daytime performance is often made worse, not better, and the lack of general health benefits is commonly misrepresented in advertising. Treatments such as the cognitive behavioral treatment of insomnia and bright light treatment of circadian rhythm disorders might offer safer and more effective alternative approaches to insomnia.

    Background Strong evidence supports that dietary modifications may decrease incident type 2 diabetes mellitus (T2DM). Numerous diabetes risk models/scores have been developed, but most do not rely specifically on dietary variables or do not fully capture the overall dietary pattern. We prospectively assessed the association of a dietary-based diabetes-risk score (DDS), which integrates optimal food patterns, with the risk of developing T2DM in the SUN (“Seguimiento Universidad de Navarra”) longitudinal study. Methods We assessed 17,292 participants initially free of diabetes, followed-up for a mean of 9.2 years. A validated 136-item FFQ was administered at baseline. Taking into account previous literature, the DDS positively weighted vegetables, fruit, whole cereals, nuts, coffee, low-fat dairy, fiber, PUFA, and alcohol in moderate amounts; while it negatively weighted red meat, processed meats and sugar-sweetened beverages. Energy-adjusted quintiles of each item (with exception of moderate alcohol consumption that received either 0 or 5 points) were used to build the DDS (maximum: 60 points). Incident T2DM was confirmed through additional detailed questionnaires and review of medical records of participants. We used Cox proportional hazards models adjusted for socio-demographic and anthropometric parameters, health-related habits, and clinical variables to estimate hazard ratios (HR) of T2DM. Results We observed 143 T2DM confirmed cases during follow-up. Better baseline conformity with the DDS was associated with lower incidence of T2DM (multivariable-adjusted HR for intermediate (25–39 points) vs. low (11–24) category 0.43 [95% confidence interval (CI) 0.21, 0.89]; and for high (40–60) vs. low category 0.32 [95% CI: 0.14, 0.69]; p for linear trend: 0.019). Conclusions The DDS, a simple score exclusively based on dietary components, showed a strong inverse association with incident T2DM. This score may be applicable in clinical practice to improve

    Patients who undergo solid organ transplantation may have preexisting diabetes mellitus (DM), develop new-onset DM after transplantation (NODAT), or have postoperative hyperglycemia that resolves shortly after surgery. Although insulin is usually used to control hyperglycemia in the hospital, following discharge most of the usual diabetes oral and parenteral medications can be used in treatment. However, when there are comorbidities such as impaired kidney or hepatic function, or heart disease, special precautions may be necessary. In addition, drug-drug interactions, such as drugs interacting with CYP3A4 enzyme pathway, require additional consideration because of possible interaction with immunosuppressive drug metabolism.

  18. The effect of foreign language in judgments of risk and benefit: The role of affect.

    As a result of globalization, policymakers and citizens are increasingly communicating in foreign languages. This article investigates whether communicating in a foreign language influences lay judgments of risk and benefit regarding specific hazards such as "traveling by airplane," "climate change," and "biotechnology." Merging findings from bilingual and risk perception research, we hypothesized that stimuli described in a foreign language, as opposed to the native tongue, would prompt more positive overall affect and through that induce lower judgments of risk and higher judgments of benefit. Two studies support this foreign language hypothesis. Contrary to recent proposals that foreign language influences judgment by promoting deliberate processing, we show that it can also influence judgment through emotional processing. The present findings carry implications for international policy, such as United Nations decisions on environmental issues. PMID:25893443

    Background In the past years, an enormous increase in the number of available health-related applications (apps) has occurred, from approximately 5800 in 2011 to over 23,000 in 2013, in the iTunes store. However, little is still known regarding the use, possible effectiveness, and risks of these applications. In this study, we focused on apps and other e-tools related to medicine use. A large subset of the general population uses medicines and might benefit from tools that aid in the use of medicine. Objective The aim of the present study was to gain more insight into the characteristics, possible risks, and possible benefits of health apps and e-tools related to medication use. Methods We first made an inventory of apps and other e-tools for medication use (n=116). Tools were coded by two independent researchers, based on the information available in the app stores and websites. Subsequently, for one type of often downloaded apps (aimed at people with diabetes), we investigated users’ experiences using an online questionnaire. Results Results of the inventory show that many apps for medication use are available and that they mainly offer simple functionalities. In line with this, the most experienced benefit by users of apps for regulating blood glucose levels in the online questionnaire was “information quick and conveniently available”. Other often experienced benefits were improving health and self-reliance. Results of the inventory show that a minority of the apps for medication use has potentially high risks and for many of the apps it is unclear whether and how personal data are stored. In contrast, online questionnaire among users of apps for blood glucose regulation indicates that they hardly ever experience problems or doubts considering reliability and/or privacy. Although, respondents do mention to experience disadvantages of use due to incomplete apps and apps with poor ease of use. Respondents not using app(s) indicate that they might use them

    Objective We investigated the overall and age-specific risks of developing breast and endometrial cancer among women with diabetes in a population-based cohort study. Methods Women with diabetes (n = 319310) and age-matched controls (n = 319308), selected from ambulatory care claims and beneficiary registry in 2000, respectively were linked to the in-patient claims (2000–2008) to identify admissions due to breast (ICD-9-CM: 174) and endometrial (ICD-9-CM: 182) cancer. The person-year approach with Poisson assumption was used to estimate the incidence density rate. The age-specific hazard ratios (HRs) of above malignancies in relation to diabetes with multivariate Cox proportional hazard regression. Results The overall incidence density rate of breast and endometrial cancer was estimated at 1.21 and 0.21 per 10,000 patient-years, respectively, for diabetes. The corresponding figures for controls were lower at 1.00 and 0.14 per 10,000 patient-years. Compared with the controls, the covariate adjusted HR for breast and endometrial cancer was 1.42 (95% confidence interval (CI) 1.34–1.50) and 1.71 (95% CI 1.48–1.97), respectively in women with diabetes. Elderly (> = 65 years) diabetes had the highest HR (1.61) of breast cancer, while the highest HR (1.85) of endometrial cancer was observed in diabetes aged < = 50 years. Conclusions Diabetes may significantly increase the risks of breast and endometrial cancer in all age stratifications. Health education for strict adherence of cancer screening program in women with diabetes is essential. PMID:23826297

    Type 2 diabetes mellitus (T2DM) is a major global health problem. The present study examines the relationship between the metabolic, anthropometric and Finnish risk score (FINDRISC) among normal and pre-diabetic adults. Subjects (n = 1319, aged above 18 years) from the Qatari population were classified into two groups based on their hemoglobin A1c (HbA1c) measurements (non-diabetic A1c<5.6% and pre-diabetic 5.6% ≤ A1c ≤ 6.4%) were examined for their anthropometric (height, weight and waist circumference), metabolic [fat, fat free mass (FFM), muscle mass (MM), total body water (TBW), bone mass, degree of obesity, basal metabolic rate (BMR), body mass index (BMI), metabolic age, visceral fat rating, systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (Total-C), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TG), fasting / random plasma glucose (FPG / RPG), HbA1c and vitamin D (VitD)] and FINDRISC. Means and frequencies were determined in aggregate and by subgroups for all variables and correlations between categorical variables were tested to estimate the association between the anthropometric and metabolic risk factors with the FINDRISC. A percentage of 74.8% (n = 987) of the study population aged below 45 years old and their overall BMI was 28.8±5.2kg/m2 (overweight). Pre-diabetic subgroup have shown a statistically higher FINDRISC compared to their non-diabetic counterparts (11.2±4.1 vs. 9.8±4, p<0.001). The FINDRISC was significantly and directly correlated with the BMI, HbA1c and FPG. However, HbA1c was correlated directly with BMI, SBP, DBP, FPG / RPG and indirectly with the levels of HDL. This study demonstrates an apparent relationship between the HbA1c and FINDRISC score. Pursuing further research on this association may permit using HbA1c with the FINDRISC in predicting the risk of T2DM to be a better tool rather than using the current FPG/RPG, OGTT methods.

    The following article, published online on 17 November 2015 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors, the journal Editor in Chief, Richard Holt and John Wiley & Sons Ltd. The retraction has been agreed due the fact the authors have made Wiley aware that there was an error in the way the diabetes prevention intervention effect was implemented in this version of the model. The underlying model is not affected by this error. However, the magnitude of the cost savings and health benefits are substantially lower than stated.

    Aims/Introduction Muscle strength training has been suggested to improve glucose metabolism; however, epidemiological evidence regarding strength training's effects on diabetes risk is scarce. We prospectively examined the association between strength training and the risk of type 2 diabetes in Japanese men and women. Materials and Methods The sample included health checkups on 26,630 Japanese male and female workers aged 30–64 years without diabetes at baseline. Weekly time spent on strength training was elicited using a self-reported questionnaire. Type 2 diabetes was diagnosed based on hemoglobin A1c, fasting glucose, random plasma glucose and self-report in an annual health checkup. Hazard ratio (HR) and its 95% confidence interval (CI) for incident diabetes was estimated using a Cox proportional hazards model. Results During a mean follow up of 5.2 years with 139,748 person-years, 1,770 individuals developed diabetes. Age- and sex-adjusted HR for diabetes was 0.58 (95% CI 0.42–0.79) in those who engaged in strength training compared with those who engaged in no strength training. After further adjusting for potential confounders, the corresponding HR was 0.66 (95% CI 0.48–0.90). Additional adjustment for body mass index did not materially change the result; the HR was 0.70 (95% CI 0.51–0.96). The association was more pronounced in individuals aged 50 years or older than those aged <50 years, although the difference in the association by age was not significant. Conclusions These results suggest that engagement in strength training could help to reduce the risk of type 2 diabetes in a Japanese working population. PMID:26543539

    An integrated benefit-risk analysis aims to give guidance in decision situations where benefits do not clearly prevail over risks, and explicit weighing of benefits and risks is thus indicated. The BEPRARIBEAN project aims to advance benefit-risk analysis in the area of food and nutrition by learning from other fields. This paper constitutes the final stage of the project, in which commonalities and differences in benefit-risk analysis are identified between the Food and Nutrition field and other fields, namely Medicines, Food Microbiology, Environmental Health, Economics and Marketing-Finance, and Consumer Perception. From this, ways forward are characterized for benefit-risk analysis in Food and Nutrition. Integrated benefit-risk analysis in Food and Nutrition may advance in the following ways: Increased engagement and communication between assessors, managers, and stakeholders; more pragmatic problem-oriented framing of assessment; accepting some risk; pre- and post-market analysis; explicit communication of the assessment purpose, input and output; more human (dose-response) data and more efficient use of human data; segmenting populations based on physiology; explicit consideration of value judgments in assessment; integration of multiple benefits and risks from multiple domains; explicit recognition of the impact of consumer beliefs, opinions, views, perceptions, and attitudes on behaviour; and segmenting populations based on behaviour; the opportunities proposed here do not provide ultimate solutions; rather, they define a collection of issues to be taken account of in developing methods, tools, practices and policies, as well as refining the regulatory context, for benefit-risk analysis in Food and Nutrition and other fields. Thus, these opportunities will now need to be explored further and incorporated into benefit-risk practice and policy. If accepted, incorporation of these opportunities will also involve a paradigm shift in Food and Nutrition benefit-risk

  6. The communication of the radiation risk from CT in relation to its clinical benefit in the era of personalized medicine: part 2: benefits versus risk of CT.

    PubMed

    Westra, Sjirk J

    2014-10-01

    In order to personalize the communication of the CT risk, we need to describe the risk in the context of the clinical benefit of CT, which will generally be much higher, provided a CT scan has a well-established clinical indication. However as pediatric radiologists we should be careful not to overstate the benefit of CT, being aware that medico-legal pressures and the realities of health care economics have led to overutilization of the technology. And even though we should not use previously accumulated radiation dose to a child as an argument against conducting a clinically indicated scan (the "sunk-cost" bias), we should consider patients' radiation history in the diagnostic decision process. As a contribution to future public health, it makes more sense to look for non-radiating alternatives to CT in the much larger group of basically healthy children who are receiving occasional scans for widely prevalent conditions such as appendicitis and trauma than to attempt lowering CT use in the smaller group of patients with chronic conditions with a limited life expectancy. When communicating the CT risk with individual patients and their parents, we should acknowledge and address their concerns within the framework of informed decision-making. When appropriate, we may express the individual radiation risk, based on estimates of summated absorbed organ dose, as an order of magnitude rather than as an absolute number, and compare this with the much larger natural cancer incidence over a child's lifetime, and with other risks in medicine and daily life. We should anticipate that many patients cannot make informed decisions on their own in this complex matter, and we should offer our guidance while maintaining respect for patient autonomy. Proper documentation of the informed decision process is important for future reference. In concert with our referring physicians, pediatric radiologists are well-equipped to tackle the complexities associated with the communication

    Background and Aims. Diabetic neuropathy is a frequent complication of type 2 diabetes mellitus (T2DM). Genetic susceptibility and oxidative stress may play a role in the appearance of T2DM and diabetic neuropathy. We investigated the relation between polymorphism in genes related to oxidative stress such as GSTM1, GSTT1, and GSTP1 and the presence of T2DM and diabetic neuropathy (DN). Methods. Samples were collected from 84 patients with T2DM (42 patients with DN and 42 patients without DN) and 98 healthy controls and genotyped by using polymerase chain reaction and restriction fragment length polymorphism method. Results. GSTP1 Ile105Val polymorphism was associated with the risk of developing T2DM (p = 0.05) but not with the risk of developing DN in diabetic cases. GSTM1 and GSTT1 gene polymorphisms were associated with neither the risk of developing T2DM nor the risk of DN occurrence in diabetic patients. No association was observed between the patients with T2DM and DSPN (diabetic sensorimotor peripheral neuropathy) and T2DM without DSPN regarding investigated polymorphism. Conclusion. Our data suggest that GSTP1 gene polymorphisms may contribute to the development of T2DM in Romanian population. GSTM1, GSTT1, and GSTP1 gene polymorphisms are not associated with susceptibility of developing diabetic neuropathy in T2DM patients. PMID:26435566

    The objective of this study was to assess the validity of prevalent and incident self-reported diabetes compared with multiple reference definitions and to assess the reliability (repeatability) of a self-reported diagnosis of diabetes. Data from 10,321 participants in the Atherosclerosis Risk in Communities (ARIC) Study who attended visit 4 (1996-1998) were analyzed. Prevalent self-reported diabetes was compared with reference definitions defined by fasting glucose and medication use obtained at visit 4. Incident self-reported diabetes was assessed during annual follow-up telephone calls and was compared with reference definitions defined by fasting glucose, hemoglobin A1c, and medication use obtained during an in-person visit attended by a subsample of participants (n = 1,738) in 2004-2005. The sensitivity of prevalent self-reported diabetes ranged from 58.5% to 70.8%, and specificity ranged from 95.6% to 96.8%, depending on the reference definition. Similarly, the sensitivity of incident self-reported diabetes ranged from 55.9% to 80.4%, and specificity ranged from 84.5% to 90.6%. Percent positive agreement of self-reported diabetes during 9 years of repeat assessments ranged from 92.7% to 95.4%. Both prevalent self-reported diabetes and incident self-reported diabetes were 84%-97% specific and 55%-80% sensitive as compared with reference definitions using glucose and medication criteria. Self-reported diabetes was >92% reliable over time. PMID:23013620

    The effect of language acculturation, socioeconomic status (SES), and immigrant generation on development of diabetes among Mexican Americans was evaluated in the Hispanic Established Population for the Epidemiologic Study of the Elderly (HEPESE). HEPESE is a longitudinal cohort study of 3,050 non-institutionalized Mexican Americans aged 65 years at baseline (1993-1994) from 5 Southwestern states. Diabetes incidence was ascertained in 4 follow-up surveys to 2004-05 by respondent self-reported physician-diagnosis of diabetes, high blood glucose, or sugar in the urine. Language of interview, immigrant generation, gender, age, education, family history of diabetes, smoking status, alcohol use, health insurance type and self-reported height and weight were assessed. High socioeconomic status (SES) was defined by high school graduation and non-Medicaid insurance. Cox's proportional hazards models were fit to evaluate the effects of language acculturation, generation and SES on incident diabetes. 845 of 3,050 (27.7%) Mexican Americans had diabetes at baseline and were younger, more educated, and more likely to have health insurance than those without diabetes. Risk of developing diabetes increased for Spanish-speaking respondents with low SES from 1st to 3rd generation (HR = 1.76, 95% CI = 1.02-3.03) and from 2nd to 3rd generation (HR = 2.15, 95% CI = 1.20-3.84). Among English-speaking, high SES participants, generation had a protective effect on developing diabetes: HR = 0.45 (95% CI = 0.22-0.91) when comparing 3rd versus 1st generation. The effect of language acculturation and immigrant generation on incident diabetes is moderated by SES status in HEPESE participants. PMID:23990075

    Background Patients with diabetes are at high risk of death prior to reaching end-stage renal disease, but most models predicting the risk of kidney disease do not take this competing risk into account. We aimed to compare the performance of Cox regression and competing risk models for prediction of early- and late-stage renal complications in type 2 diabetes. Methods Patients with type 2 diabetes participating in the observational ZODIAC study were included. Prediction models for (micro)albuminuria and 50% increase in serum creatinine (SCr) were developed using Cox regression and competing risk analyses. Model performance was assessed by discrimination and calibration. Results During a total follow-up period of 10 years, 183 out of 640 patients (28.6%) with normoalbuminuria developed (micro)albuminuria, and 22 patients (3.4%) died without developing (micro)albuminuria (i.e. experienced the competing event). Seventy-nine out of 1,143 patients (6.9%) reached the renal end point of 50% increase in SCr, while 219 (19.2%) died without developing the renal end point. Performance of the Cox and competing risk models predicting (micro)albuminuria was similar and differences in predicted risks were small. However, the Cox model increasingly overestimated the risk of increase in SCr in presence of a substantial number of competing events, while the performance of the competing risk model was quite good. Conclusions In this study, we demonstrated that, in case of substantial numbers of competing events, it is important to account for the competing risk of death in renal risk prediction in patients with type 2 diabetes.

    In the United States, 10.9 million people are receiving Social Security Disability Insurance (SSDI) benefits with an average pay of $12,000 per year. If the U.S. House of Congress fails to enact a new bill by the end of fiscal-year 2016, SSDI benefits are estimated to be reduced by $2,300 per-person per year. In the pass, the U.S. Congre
