Type 2 diabetes increases the risk of developing cardiovascular (CV) complications such as myocardial infarction, heart failure, stroke, peripheral vascular disease, and CV-associated mortality. Strict glycemic control in diabetics has shown improvement in microvascular complications related to diabetes but has been unable to demonstrate major effects on macrovascular complications including myocardial infarction and stroke. Conventional therapies for diabetes that include insulin, metformin, sulfonylureas (SU), and alpha-glucosidase inhibitors have limited and/or controversial data on CV safety based on observational studies not designed or powered to assess CV safety of these medications. In 2008, the US Food and Drug Administration (FDA) revised regulations for the approval of medications for type 2 diabetes by requiring that enough CV events are accrued prior to approval to rule out an upper 95 % confidence interval (95 % CI) for HR of 1.8 for CV events, followed by ruling out an upper 95 % CI for HR of 1.3 in the post-approval period. To date, novel diabetes therapies including peroxisome proliferator-activated receptor (PPAR) gamma agonists, dipeptidyl peptidase-4 (DPP4) inhibitors, glucagon-like peptide 1 (GLP 1) analogs, and sodium-glucose transporter-2 (SGL2) inhibitors have been evaluated in CV safety trials. Results from the first major CV outcome studies in type 2 diabetes, SAVOR-TIMI 53 and EXAMINE, have shown that neither saxagliptin nor alogliptin had increases in major CV events relative to placebo in high-risk patients. Ongoing and future trials will elucidate the CV safety for other DPP-4 inhibitors compared to SUs and the GLP-1 agonists versus placebo. 相似文献

Tumor necrosis factor alpha (TNFalpha) plays a key role in orchestrating the complex events involved in inflammation and immune response. The presence of single nucleotide polymorphisms (SNPs) within the promoter region of the TNFa gene has been associated with a number of diseases. The aim of this study was to investigate the distribution of polymorphisms at positions -238 (G/A) and -308 (G/A) at the TNFalpha promoter, and its association to the outcome of different clinical forms of leprosy. Furthermore, the bacteriological index (BI) was evaluated among genotyped multibacillary (MB) patients in order to investigate the possible influence of each polymorphism on the bacterial load. This study included a total of 631 leprosy patients being 401 MB and 230 paucibacillary (PB), that was further separated according to its ethnicity (Afro- and Euro-Brazilians). The combination of SNPs in haplotypes generated three different arrangements: TNFG-G, TNFG-A and TNFA-G. In spite of the marked differences observed in the frequency of the haplotypes along the ethnic groups, no statistical differences were observed in haplotype frequencies between MB and PB patients. The BI analyses showed a lower bacteriological index among the -308 carriers, while the BI of the -238 carriers was higher. Although no significance has been achieved in this analysis regarding the influence of the polymorphisms to the development of the clinical outcome, it seems that in a different stage (among the MB patients) the polymorphisms could contribute to the degree of severity observed. 相似文献

Background
Gemstones have been in use as part of alternative and complementary medicine for years. However, our understanding of the perceived healing powers of gemstones is limited. An extensive literature search revealed that there is a dearth of validated information on this subject. This study was therefore undertaken to explore the various aspects of the knowledge, attitudes, and practices of the public towards gemstone therapeutics. 相似文献8.
