Longitudinal study of lung function in pregnant women: Influence of parity and smoking

Clinics; 72 (10), 2017
OBJECTIVES: To evaluate pulmonary function in the first and third trimesters of pregnancy and analyze the influence of parity and smoking on spirometry parameters. METHODS: This longitudinal prospective study included a cohort of 120 pregnant women. The inclusion criteria were as follows: singleton preg...

Non-Sustained Ventricular Tachycardia Episodes Predict Future Hospitalization in ICD Recipients with Heart Failure

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: Implantable cardioverter-defibrillator (ICD) therapy is well known to reduce mortality in selected patients with heart failure (HF). Objective: To investigate whether monitored episodes of non-sustained ventricular tachycardia (NSVT) might predict future HF hospitalizations in ICD ...

Pre-Frailty Increases the Risk of Adverse Events in Older Patients Undergoing Cardiovascular Surgery

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: Frailty is identified as a major predictor of adverse outcomes in older surgical patients. However, the outcomes in pre-frail patients after cardiovascular surgery remain unknown. Objective: To investigate the main outcomes (length of stay, mechanical ventilation time, stroke and i...

Pre-Participation Physical Fitness does not Influence Adherence to a Supervised Exercise Program

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: Exercise-based cardiac rehabilitation tends to reduce mortality. However, it requires medium/long-term adherence to regular physical exercise. It is relevant to identify the variables that affect adherence to an supervised exercise program (SEP). Objective: To evaluate the influenc...

Twenty-four hour Blood Pressure in Obese Patients with Moderate-to-Severe Obstructive Sleep Apnea

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: Obesity, systemic arterial hypertension (SAH) and obstructive sleep apnea (OSA) are closely related. Up to 70% of patients with OSA may be asymptomatic, and there is evidence that these patients have cardiovascular disease, especially nocturnal SAH. Objectives: The aim of this stud...

Angiotensin-Converting Enzyme ID Polymorphism in Patients with Heart Failure Secondary to Chagas Disease

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: Changes in the angiotensin-converting enzyme (ACE) gene may contribute to the increase in blood pressure and consequently to the onset of heart failure (HF). The role of polymorphism is very controversial, and its identification in patients with HF secondary to Chagas disease in the...

Impact of Paclitaxel-Eluting Balloons Compared to Second-Generation Drug-Eluting Stents for of In-Stent Restenosis in a Primarily Acute Coronary Syndrome Population

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: The place of drug-eluting balloons (DEB) in the treatment of in-stent restenosis (ISR) is not well-defined, particularly in a population of all-comers with acute coronary syndromes (ACS). Objective: Compare the clinical outcomes of DEB with second-generation drug-eluting stents (DE...

Causes and Predictors of In-Hospital Mortality in Patients Admitted with or for Heart Failure at a Tertiary Hospital in Brazil

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: Although heart failure (HF) has high morbidity and mortality, studies in Latin America on causes and predictors of in-hospital mortality are scarce. We also do not know the evolution of patients with compensated HF hospitalized for other reasons. Objective: To identify causes and p...

Dentin pretreatment and adhesive temperature as affecting factors on bond strength of a universal adhesive system

J. appl. oral sci; 25 (5), 2017
Abstract Objectives: To evaluate the effects of dentin pretreatment and temperature on the bond strength of a universal adhesive system to dentin. Material and Methods: Ninety-six extracted non-carious human third molars were randomly divided into 12 groups (n=8) according to Scotchbond Universal Adhes...

Effectiveness of a new non-hydrogen peroxide bleaching agent after single use - a double-blind placebo-controlled short-term study

J. appl. oral sci; 25 (5), 2017
Abstract Tooth whitening represents perhaps the most common aesthetic procedure in dentistry worldwide. The efficacy of bleaching depends on three aspects: bleaching agent, bleaching method, and tooth color. Objective: This in vivo study aimed to examine whitening effects on frontal teeth of the upper a...
