OBJECTIVE The objective of this study was to determine the association of seasonal climatic conditions with the incidence of Pseudomonas aeruginosa infections. METHODS A retrospective study was carried out to evaluate all infections caused by P. aeruginosa in a 660-bed tertiary-care hospital in Brazil over a period of 5 years. To assess seasonal patterns,(More)
AIM The aim of the present study was to evaluate the effects of the temperature of ingested water on performance during a 40-km self-paced cycling trial in the heat (35º C and 60% relative humidity). METHODS The study was randomized, counterbalanced, crossover and single-blinded. Ten well-trained male cycling athletes (cyclists, mountain bikers or(More)
The purpose of this study was to assess the intensity of official Futsal matches, expressed in different ways. Fourteen male professional Futsal players from a First Division Brazilian team volunteered to participate in this study. Maximal oxygen uptake (VO(2)max) and the heart hate (HR) and oxygen uptake (VO(2)) correlation were determined for each player.(More)
This editorial is for the special issue "Temperature sciences in Brazil" of the journal Temperature. It focuses on the physical performance and environmental conditions during the 2014 World Cup and the coming 2016 Summer Olympics. It emphasizes that a hot and humid environment imposes a great challenge to the human thermoregulation system, can lead to(More)
BACKGROUND AND OBJECTIVES We did not find clinical studies of the alkalization of ropivacaine in the literature. The objectives of this study were: (1) to determine the quantity of sodium bicarbonate (NaHCO(3)), which alkalinizes 0.75% ropivacaine (with and without adrenaline); (2) to verify the physico-chemical alterations arising from this alkalization;(More)
The purpose of this study was to investigate the effects of a 6-week aerobic training period on the time to fatigue (t lim) during exercise performed at the maximal lactate steady state (MLSS). Thirteen untrained male subjects (TG; age 22.5 ± 2.4 years, body mass 72.9 ± 6.7 kg and VO2max 44.9 ± 4.8 mL kg−1 min−1) performed a cycle ergometer test until(More)
This study examined the effects of precooling on performance and pacing during 30-km cycling exercise in hot and temperate environments. 8 trained male cyclists performed 4 trials involving either cooling (PRECTEMP and PRECHOT) or no-cooling interventions (TEMP and HOT) prior to a 30-km self-paced cycling exercise in either a hot (35°C, 68% relative(More)
BACKGROUND The aim of the present study was to compare the power output at the maximal lactate steady state (MLSS) with the power output at the individual anaerobic threshold (IAT) and at the onset of blood lactate accumulation (OBLA) in both temperate (TEMP) (22 °C) and hot (HOT) (40 °C) climates. METHODS Eight young active male (23.9±2.4 yr, 75.9±7.3 kg(More)
The aim of this study was to compare locomotor activity profiles of Brazilian top-class female soccer players competing at distinct age brackets (U17, U20, and Senior). External match load of 14 U17, 14 U20, and 17 Senior female soccer players competing in 6-7 full official international matches were assessed using global positioning systems (GPS). Total(More)
PURPOSE This study proposes to assess MBL serum concentrations in HPV positive women that developed high risk preinvasive lesions, CIN III. MATERIALS AND METHODS A total of 90 consecutive women (mean age 32.2 years, range 18-45 years) with CIN III lesions confirmed by cone biopsy were enrolled as cases at the gynecology cancer department of the Erasto(More)
