Obesity as a predictive factor for chronic kidney disease in adults: systematic review and meta-analysis.

Chronic kidney disease (CKD) is one of the main chronic diseases affecting the world population due to its high prevalence and increasing morbidity. Similarly, obesity gained the interest of the scientific community as it directly or indirectly increases mortality from cardiovascular causes, and its prevalence characterizes a pandemic. The objective of this study was to investigate obesity measured by body mass index as a predictor for end-stage renal disease in the general adult population. A systematic review and meta-analysis was carried out by searching 10 databases for prospective or retrospective cohort studies, with no restrictions on the language of publication, including adults with obesity without previous renal disease and who evolved to CKD (diagnosed by estimated glomerular filtration rate below 60 mL&mac_middot;min-1&mac_middot;(1.73 m2)-1 over the follow-up period. The R software and Meta package were used for data analysis. After removing duplicates, 5431 studies were submitted to the steps of the systematic review, and 21 articles were included in the data analysis. In total, 3,504,303 patients, 521,216 with obesity, and an average follow-up time of 9.86 years were included. The relative risk of obese people for developing CKD in the random effects model was 1.81 (95%CI: 1.52-2.16). The evidence found in this meta-analysis confirmed that obese people are at higher risk of developing CKD that the non-obese population (1.81 times higher), with obesity being a priority risk factor in preventive actions.

A Vascular Complications Risk (VASCOR) score for patients undergoing invasive cardiac procedures in the catheterization laboratory setting: A prospective cohort study.

BACKGROUND: Vascular complications are still common in the catheterization laboratory setting. However, no risk scores for their prediction have been described. With a view to bridging this gap, the present study sought to develop and validate a score for prediction of vascular complications associated with arterial access in patients undergoing interventional cardiology procedures. METHODS: This prospective multicenter cohort study included adult patients who underwent cardiac catheterization via the femoral or radial route. The outcomes of interest were: access site hematoma; major and minor bleeding; and retroperitoneal hemorrhage, pseudoaneurysm, or arteriovenous fistula requiring surgical repair. Past medical history as well as pre-procedural, intra-procedural, and post-procedural variables were collected. Patients were randomly allocated to the derivation or validation cohorts at a 2:1 ratio. The following equation constituted the score: (>6F introducer sheath×4.0)+(percutaneous coronary intervention×2.5)+(history of vascular complication after prior interventional cardiology procedure×2.0)+(prior use of warfarin or phenprocoumon×2.0)+(female sex×1.5)+(age⩾60 years×1.5). The maximum score is 13.5 points. RESULTS: A score dichotomized at ⩾3 (best cutoff for balancing sensitivity and specificity) was moderately accurate (sensitivity=0.66 (95% confidence interval: 0.59-0.73); specificity=0.59 (95% confidence interval: 0.56-0.61)). Patients with a score ⩾3 were at increased risk of complications (odds ratio: 2.95; 95% confidence interval: 2.22-3.91). CONCLUSIONS: This study yielded a score that is capable of predicting vascular complications and easily applied in daily practice by providers working in the catheterization laboratory setting.

Weight gain adequacy and pregnancy outcomes in gestational diabetes: a meta-analysis.

The Institute of Medicine updated guidelines for gestational weight gain in 2009, with no special recommendations for gestational diabetes. Our objectives were to describe the prevalence of weight gain adequacy and their association with adverse pregnancy outcomes in gestational diabetes. We searched MEDLINE, EMBASE, COCHRANE and SCOPUS. We calculated the pooled prevalence of gain adequacy and relative risks for pregnancy outcomes within Institute of Medicine categories. Thirty-three studies/abstracts (88,599 women) were included. Thirty-one studies provided data on the prevalence of weight gain adequacy; it was adequate in 34% (95% CI: 29-39%) of women, insufficient in 30% (95% CI: 27-34%) and excessive in 37% (95% CI: 33-41%). Excessive gain was associated with increased risks of pharmacological treatment, hypertensive disorders of pregnancy, caesarean section, large for gestational age and macrosomic babies, compared to adequate or non-excessive gain. Weight gain below the guidance had a protective effect on large babies (RR: 0.71; 95% CI: 0.56-0.90) and macrosomia (RR 0.57; 95% CI 0.40-0.83), and did not increase the risk of small babies (RR 1.40; 95% CI 0.86-2.27). Less than recommended weight gain would be beneficial, while effective prevention of excessive gain is of utmost importance, in gestational diabetes pregnancies. Nevertheless, no ideal range for weight gain could be established.
