Type 2 diabetes is a syndrome characterized by relative insulin deficiency, insulin resistance and increased hepatic glucose output. Medications used to treat the disease are designed to correct one or more of these metabolic abnormalities. Current recommendations of the American Diabetes Association (ADA) and European Association for the Study of Diabetes (EASD) include diet and exercise as first-line therapy plus hypoglycemic drugs. Actually there are seven distinct classes of anti-hyperglicemic agents, each of them displaying unique pharmacologic properties. The aim of this review is to describe the pathophysiological basis of their mechanism of action, a necessary step to individualize treatment of diabetic people, taking into proper consideration potential benefits and secondary effects of drugs.
Background: Few studies evaluated the clinical outcomes of Community Acquired Pneumonia (CAP), Hospital-Acquired Pneumonia (HAP) and Health Care-Associated Pneumonia (HCAP) in relation to the adherence of antibiotic treatment to the guidelines of the Infectious Diseases Society of America (IDSA) and the American Thoracic Society (ATS) in hospitalized elderly people (65 years or older). Methods: Data were obtained from REPOSI, a prospective registry held in 87 Italian internal medicine and geriatric wards. Patients with a diagnosis of pneumonia (ICD-9 480-487) or prescribed with an antibiotic for pneumonia as indication were selected. The empirical antibiotic regimen was defined to be adherent to guidelines if concordant with the treatment regimens recommended by IDSA/ATS for CAP, HAP, and HCAP. Outcomes were assessed by logistic regression models. Results: A diagnosis of pneumonia was made in 317 patients. Only 38.8% of them received an empirical antibiotic regimen that was adherent to guidelines. However, no significant association was found between adherence to guidelines and outcomes. Having HAP, older age, and higher CIRS severity index were the main factors associated with in-hospital mortality. Conclusions: The adherence to antibiotic treatment guidelines was poor, particularly for HAP and HCAP, suggesting the need for more adherence to the optimal management of antibiotics in the elderly with pneumonia
The relationship between obesity and mortality in people with type 2 diabetes has not been definitely assessed. We have examined this issue in a well-characterized population-based cohort of Mediterranean diabetic people. Standardized anthropometric data from the population-based Casale Monferrato Study have been prospectively analyzed. The cohort included 1,475 people (62.6% aged ≥65 years) who had been recruited in 1991 and followed-up to December 31, 2006. Cox proportional hazards modeling was employed to estimate the independent associations between all-cause and cardiovascular mortality and BMI. Out of 1,475 people, 972 deaths occurred during a 15-year follow-up. Cox regression analyses showed that with respect to BMI <24.2 kg/m(2), values of 30.0 kg/m(2) and over were associated with lower all-cause and cardiovascular mortality risk (HR = 0.68, 95% CI 0.56-0.85, P for trend = 0.001; HR = 0.59, 0.44-0.80, P for trend = 0.002), independently of classical and new risk factors. As interaction between age and BMI was significant, we performed a stratified analysis by age, providing evidence that our finding was entirely due to a significant protective effect of BMI of 30.0 kg/m(2) and over in the elderly (all-cause mortality HR = 0.75, 95% CI 0.58-0.96; cardiovascular mortality HR = 0.67, 95% CI 0.45-0.95). In contrast, obesity was not significantly associated with mortality risk in diabetic subjects aged <65 years. Results were confirmed even excluding from the analysis individuals who died within 2 years of follow-up, smokers and those with CHD. In Mediterranean diabetic people aged ≥65 years, obesity is significantly associated with lower 15-year mortality risk. In contrast, it was not significantly associated with mortality risk in diabetic subjects aged <65 years. As more than two-thirds of people with type 2 diabetes are elderly, our findings, if confirmed, could have clinical implications.
A rate-control strategy is the most widely used among elderly AF patients with multiple comorbidities and polypharmacy. No differences were evident in CV death and all-cause death at follow-up.
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.
