Comparative Study
Comparison of diabetic ketoacidosis in patients with type-1 and type-2 diabetes mellitus.
Diabetic ketoacidosis (DKA) occurs most often in patients with type 1 diabetes, however patients with type 2 diabetes are also susceptible to DKA under stressful conditions. The aims of our study were to evaluate and compare the clinical and biochemical characteristics and outcomes of type 1 versus type 2 diabetes mellitus (DM) patients with DKA. ⋯ DKA in patients with type-2 DM is a more severe disease with worse outcomes compared with type-1 DM. Advanced age, mechanical ventilation and bed-ridden state were independent predictors of 30-day mortality.

An estimated 25.8 million children and adults in the United States, approximately 8.3% of the population, have diabetes. Diabetes prevalence varies by race and ethnicity. African Americans have the highest prevalence (12.6%), followed closely by Hispanics (11.8%), Asian Americans (8.4%) and whites (7.1%). ⋯ Finally, advances in telemedicine technology are discussed that show improvements in metabolic control and cardiovascular risk in adults with type 2 diabetes. Improving provider and patient understanding of diabetes complications may improve management and self-care practices that are important for diabetes control. Telemedicine may improve access to diabetes specialists and may improve self-management education and diabetes control particularly in rural and underserved communities.

Review Meta Analysis
The role of TNF-α 308G>A polymorphism in the risk for ischemic stroke.
Stroke is a common health problem; however, its pathogenesis is not clear. Several studies have examined the association of -308G>A promoter polymorphism in the tumor necrosis factor-α gene (TNF-α) with ischemic stroke susceptibility. However, the results of these studies are inconsistent and the sample sizes of most of the studies were small. Thus, a meta-analysis was conducted to provide a more robust estimate of the effect of the TNF-α 308G>A polymorphism on the risk for ischemic stroke. ⋯ This study suggests that TNF-α 308G>A polymorphism is associated with the risk for juvenile ischemic stroke, whereas it is a protective factor for ischemic stroke in Asians and the adult population. However, in the overall analysis and in Caucasians, a significant association was not found.

: The lack of specific clinical manifestations for sepsis frequently leads to delayed diagnosis. Identification of sensitive and specific indicators that can be easily assessed, accurately reflect infection severity and prognosis and are clinically important in the differential diagnosis of sepsis, is of great significance. The purpose of this study was to evaluate the diagnostic and prognostic value of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) in high selected, mostly postoperative patients with suspicion of sepsis. ⋯ : In postoperative patients, plasma levels of sTREM-1 and TNF-α could differentiate sepsis from SIRS. sTREM levels also reflected the severity of sepsis and were noninferior for prognosis compared with other biochemical indexes.

Oxidative stress has been implicated in the pathogenesis of cardiovascular disorders, including atherosclerosis. In pharmacological doses, niacin (vitamin B3) was proven to reduce total cholesterol, triglyceride, very-low-density lipoprotein, and low-density lipoprotein levels, and to increase high-density lipoprotein (HDL) levels. The aim of this study was to evaluate the effect of niacin treatment in patients with low levels of HDL cholesterol (HDL-C; <40 mg%) on their lipid profile and oxidative stress status. ⋯ Although serum CRP levels were not affected by niacin treatment, a correlation between CRP and HDL levels was obtained when computing the results. Niacin treatment in hypercholesterolemic patients with low HDL levels caused a significant decrease in their oxidative stress status. These results indicate an additional beneficial effect of niacin beyond its ability to affect the lipid profile.
