Effect of a multifaceted quality improvement intervention on the prescription of evidence based treatment in patients at high cardiovascular risk in Brazil The BRIDGE Cardiovascular Prevention Cluster Randomized Clinical Trial

RESULTS Of the 1619 included patients,1029 (63.6%) weremale,1327(82.0%) had coronary artery disease (843[52.1%] with prioracutemyo cardial infarction),355(21.9%)had priorischemicstroke ortransientischemicattack,and197 (12.2%) had peripheral vascular disease,andthemean( SD) age was 65.6 (10.5) years. Among randomized clusters, 30 (75%) were cardiology sites, 6 (15%) were primary careunits,and 26 (65%) were teaching institutions.Amonge ligible patients,thosein intervention clusters were more like ly to receive aprescription of evidence-based therapies thant hose in control clusters (73.5%[515of701] vs58.7% [493of840];oddsratio,2.30;95%CI,1.14-4.65). There were no differences between the intervention and control group swithregard storisk factor control(ie,hyperlipidemia,hypertension,ordiabetes).Ratesofeducationforsmokingcessationwere higher among current smokers in the intervention group thanin the control group (51.9%[364of701] vs18.2%[153of840];oddsratio,11.24;95%CI,2.20-57.43).Therateofcardiovascularmortality,acute myocardial infarction,andstrokewas2.6%for patients from intervention cluster sand 3.4%forthose in the control group (hazardratio, 0.76;95%CI,0.43-1.34).

Obstructive sleep apnea, hypertension and cardiovascular diseases

Obstructive sleep apnea (OSA) is characterized by recurrent episodes of partial (hypopnea) or complete interruption (apnea) in breathing during sleep due to airway collapse in the pharyngeal region. OSA and its cardiovascular consequences have been widely explored in observational and prospective studies. Most evidence verifies the positive relationship between OSA and hypertension, coronary artery disease, atrial fibrillation, stroke and heart failure. However, more studies are needed to better assess the impact of OSA, and possible benefit of treatment with continuous positive airway pressure (CPAP) on dyslipidemia, type 2 diabetes, insulin resistance and cardiovascular mortality. The leading pathophysiological mechanisms involved in the changes triggered by OSA, include intermittent hypoxemia and re-oxygenation, arousals and changes in intrathoracic pressure. Hypertension is strongly related with activation of the sympathetic nervous system, stimulation of the renin–angiotensin–aldosterone system and impairment of endothelial function. The high prevalence of OSA in the general population, hypertensive patients and especially obese individuals and patients resistant to antihypertensive therapy, highlights the need for effective screening, diagnosis and treatment of OSA to decrease cardiovascular risk.

Sarcopenia in chronic kidney disease on conservative therapy: prevalence and association with mortality

BACKGROUND:In chronic kidney disease (CKD), multiple metabolic and nutritional abnormalities contribute to the impairment of skeletal muscle mass and function thus predisposing patients to the condition of sarcopenia. Herein, we investigated the prevalence and mortality predictive power of sarcopenia, defined by three different methods, in non-dialysis-dependent (NDD) CKD patients.METHODS:We evaluated 287 NDD-CKD patients in stages 3-5 [59.9 ± 10.5 years; 62% men; 49% diabetics; glomerular filtration rate (GFR) 25.0 ± 15.8 mL/min/1.73 m(2)]. Sarcopenia was defined as reduced muscle function assessed by handgrip strength (HGS <30th percentile of a population-based reference adjusted for sex and age) plus diminished muscle mass assessed by three different methods: (i) midarm muscle circumference (MAMC) <90% of reference value (A), (ii) muscle wasting by subjective global assessment (B) and (iii) reduced skeletal muscle mass index (<10.76 kg/m² men; <6.76 kg/m² women) estimated by bioelectrical impedance analysis (BIA) (C). Patients were followed for up to 40 months for all-cause mortality, and there was no loss of follow-up.RESULTS:The prevalence of sarcopenia was 9.8% (A), 9.4% (B) and 5.9% (C). The kappa agreement between the methods were 0.69 (A versus B), 0.49 (A versus C) and 0.46 (B versus C). During follow-up, 51 patients (18%) died, and the frequency of sarcopenia was significantly higher among non-survivors. In crude Cox analysis, sarcopenia diagnosed by the three methods was associated with a higher hazard for mortality; however, only sarcopenia diagnosed by method C remained as a predictor of mortality after multivariate adjustment...
