Beta-blocker therapy in elderly patients with renal dysfunction and heart failure.

OBJECTIVE: To assess the role of beta-blockers (BB) in patients with chronic kidney disease (CKD) aged ≥ 75 years. METHODS AND RESULTS: From January 2008 to July 2014, we included 390 consecutive patients ≥ 75 years of age with ejection fraction ≤ 35% and glomerular filtration rate (GFR) ≤ 60 mL/min per 1.73 m2. We analyzed the relationship between treatment with BB and mortality or cardiovascular events. The mean age of our population was 82.6 ± 4.1 years. Mean ejection fraction was 27.9% ± 6.5%. GFR was 60-45 mL/min per 1.73 m2 in 50.3% of patients, 45-30 mL/min per 1.73 m2 in 37.4%, and < 30 mL/min per 1.73 m 2 in 12.3%. At the conclusion of follow-up, 67.4% of patients were receiving BB. The median follow-up was 28.04 (IR: 19.41-36.67) months. During the study period, 211 patients (54.1%) died and 257 (65.9%) had a major cardiovascular event (death or hospitalization for heart failure). BB use was significantly associated with a reduced risk of death (HR = 0.51, 95% CI: 0.35-0.74;P < 0.001). Patients receiving BB consistently showed a reduced risk of death across the different stages of CKD: stage IIIa (GFR = 30-45 mL/min per 1.73 m 2; HR = 0.47, 95% CI: 0.26-0.86,P < 0.0001), stage IIIb (GFR 30-45 mL/min per 1.73 m 2; HR = 0.55, 95% CI: 0.26-1.06,P = 0.007), and stages IV and V (GFR < 30 mL/min per 1.73 m 2; HR = 0.29, 95% CI: 0.11-0.76;P = 0.047). CONCLUSIONS: The use of BB in elderly patients with HFrEF and renal impairment was associated with a better prognosis. Use of BB should be encouraged when possible.

Effectiveness of Following Mediterranean Diet Recommendations in the Real World in the Incidence of Gestational Diabetes Mellitus (GDM) and Adverse Maternal-Foetal Outcomes: A Prospective, Universal, Interventional Study with a Single Group. The St Carlos Study.

We reported that a Mediterranean Diet (MedDiet), supplemented with extra-virgin olive oil (EVOO) and pistachios, reduces GDM incidence and several other adverse outcomes. In order to assess its translational effects in the real world we evaluated the effect of MedDiet from 1st gestational visit in GDM rate compared with control (CG) and intervention (IG) groups from the previously referred trial. As secondary objective we also compared adverse perinatal outcomes between normoglycemic and diabetic women. This trial is a prospective, clinic-based, interventional study with a single group. 1066 eligible normoglycaemic women before 12 gestational weeks were assessed. 932 women (32.4 ± 5.2 years old, pre-gestational BMI 22.5 ± 3.5 kg/m2) received a motivational lifestyle interview with emphasis on daily consumption of EVOO and nuts, were followed-up and analysed. Binary regression analyses were used to examine the risk for each pregnancy outcome, pregnancy-induced hypertension, preeclampsia, gestational weight gain (GWG), caesarean-section, perineal trauma, preterm delivery, small (SGA) and large for gestational age (LGA), and Neonatal Intensive Care Unit admissions. GDM was diagnosed in 13.9%. This rate was significantly lower than the CG: RR 0.81 (0.73-0.93), p < 0.001 and no different from the IG: RR 0.96 (0.85-1.07), p = 0.468. GWG was lower in diabetic women (10.88 ± 6.46 vs. 12.30 ± 5.42 Kg; p = 0.013). Excessive weight gain (EWG) was also lower in GDM [RR 0.91 (0.86-0.96); p < 0.001] without a significant increase of insufficient weight gain. LGA were also lower (1 (0.8%) vs. 31 (3.9%); p < 0.05)), and SGA were similar (5 (3.8%) vs. 30 (3.7%)). LGA were associated to EWG (RR 1.61 (1.35-1.91), p < 0.001). Differences in other maternal-foetal outcomes were not found. In conclusions an early MedDiet nutritional intervention reduces GDM incidence and maternal-foetal adverse outcomes and should be universally applied as 1st line therapy. GDM might not be consider as a high risk pregnancy any longer.
