BACKGROUND This study was design to investigate the prognostic value for death at day-28 of lactate course and lactate clearance during the first 24 hours in Intensive Care Unit (ICU), after initial resuscitation. METHODS Prospective, observational study in one surgical ICU in a university hospital. Ninety-four patients hospitalized in the ICU for severe sepsis or septic shock were included. ...

We examined whether an increase in skin temperature or the rate of increase in core body temperature influences the relationship between minute ventilation (Ve) and core temperature during prolonged exercise in the heat. Thirteen subjects exercised for 60 min on a cycle ergometer at 50% of peak oxygen uptake while wearing a suit perfused with water at 10 degrees C (T10), 35 degrees C (T35), or ...

As diverse therapeutic options are now available for advanced melanoma patients, predictive markers that may assist treatment decision are needed. A model based on baseline serum lactate dehydrogenase (LDH), peripheral blood relative lymphocyte counts (RLC) and eosinophil counts (REC) and pattern of distant metastasis, has been recently proposed for pembrolizumab-treated patients. Here, we appl...

Cardioventilatory variables and blood-gas, acid-base status were measured in cannulated white sturgeon (Acipenser transmontanus) maintained at 19 degrees C during normocapnic and hypercapnic (Pw(CO(2)) approximately 20 Torr) water conditions and after the injection of adrenergic analogs. Hypercapnia produced significant increases in arterial PCO(2), ventilatory frequency, and plasma concentrati...

Patients with panic disorder experience panic attacks after intravenous sodium lactate infusions by an as yet unexplained mechanism. Lactate elicits a panic-like response in rats with chronic dysfunction of GABA neurotransmission in the dorsomedial hypothalamus (DMH). The circumventricular organs, organum vasculosum lamina terminalis (OVLT) and subfornical organ (SFO), are potential sites that ...

sleep deprivation has negative effects on performance and resulted in elevating of mortality risk, cardiovascular disease and diabetes. the purpose of this study was to investigate the effects of 30 hour sleep deprivation on serum levels of c-reactive protein, blood lactate, muscular strength and physiological factors of rast test in active students. the present study was a semi-experimental on...

AIM To develop a badminton specific test to determine on court aerobic and anaerobic performance. METHOD The test was evaluated by using a lactate steady state test. Seventeen male competitive badminton players (mean (SD) age 26 (8) years, weight 74 (10) kg, height 179 (7) cm) performed an incremental field test on the badminton court to assess the heart rate turn point (HRTP) and the individ...
