This protocol recommends active monitoring for 4 weeks, relying predominantly on troponin and C-reactive protein results. It encourages continuation of clozapine in the presence of mild illness, but defines a threshold for cessation.
OBJECTIVEPeople with diabetes frequently develop vascular disease. We investigated the relationship between blood 25-hydroxyvitamin D (25OH-D) concentration and vascular disease risk in type 2 diabetes.
RESEARCH DESIGN AND METHODSThe relationships between blood 25OH-D concentration at baseline and the incidence of macrovascular (including myocardial infarction and stroke) and microvascular (retinopathy, nephropathy, neuropathy, and amputation) disease were analyzed with Cox proportional hazards models and logistic regression in an observational study of patients in the 5-year Fenofibrate Intervention and Event Lowering in Diabetes trial.
RESULTSA total of 50% of the patients had low vitamin D concentrations, as indicated by median blood 25OH-D concentration of 49 nmol/L. These patients with a blood 25OH-D concentration <50 nmol/L had a higher cumulative incidence of macrovascular and microvascular events than those with levels ‡50 nmol/L. Multivariate analysis, stratified by treatment and adjusted for relevant confounders, identified blood 25OH-D concentration as an independent predictor of macrovascular events. A 50 nmol/L difference in blood 25OH-D concentration was associated with a 23% (P = 0.007) change in risk of macrovascular complications during the study, and further adjustments for seasonality, hs-CRP, and physical activity level had little impact. The unadjusted risk of microvascular complications was 18% (P = 0.006) higher during the study, though the excess risk declined to 11-14% and lost significance with adjustment for HbA 1c , seasonality, or physical activity.
CONCLUSIONSLow blood 25OH-D concentrations are associated with an increased risk of macrovascular and microvascular disease events in type 2 diabetes. However, a causal link remains to be demonstrated.Diabetes is among the leading causes of death and affects 347 million people worldwide. The World Health Organization expects a 50% increase in deaths from diabetes over the next 10 years, and by 2030, diabetes is projected to be the seventh leading cause of death (1). Most major complications involve large vessel (macrovascular) or small vessel (microvascular) disease.
Our data indicate that subclinical thyroid disease in women in the community is not associated with lower well-being or impaired health-related quality of life and SCH is not associated with increased serum markers of CVD risk.
Eosinophil counts should not be relied on for diagnosis of clozapine-related myocarditis, but elevated CRP may be an early indicator of developing myocarditis. Patients starting clozapine should be actively monitored for myocarditis during the first 4 weeks, with extra care taken during week 3.
The aim of this cross-sectional study was to determine the prevalence and identify determinants of reduced bone mineral density (BMD) in adults with cystic fibrosis (CF).Adults (88) with CF (mean¡SD age 29.9¡7.7 yrs; forced expiratory volume in one second (FEV1) 58.2¡21.5% of the predicted value) were studied. BMD at the lumbar spine (LS) and femoral neck (FN) and body composition were measured using dual-energy X-ray absorptiometry. Blood and urine were analysed for hormones, bone turnover markers, and the cytokines tumour necrosis factor-a, and interleukin-6 and -1b. FEV1 (% pred); CF genotype; malnutrition; history of growth, development or weight gain delays; and corticosteroid use were analysed.BMD Z-scores were -0.58¡1.30 (mean¡SD) at the LS and -0.24¡1.19 at the FN. Z-scores of ,-2.0 were found in 17% of subjects. Subjects who were homozygous or heterozygous for the DF508 mutation exhibited significantly lower Z-scores than those with no DF508 allele. Multiple linear regression showed that the DF508 genotype and male sex were independently associated with lower BMD at both sites. Other factors also independently associated with lower BMD included malnutrition, lower 25-hydroxyvitamin D level, lower fat-free mass and lower FEV1 (% pred).In conclusion, reduced bone mineral density in cystic fibrosis is associated with a number of factors, including DF508 genotype, male sex, greater lung disease severity and malnutrition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
