Acting centrally, dopamine has been shown to induce ergogenic effects derived from its influence on thermoregulation, motivation, reward, and motor control. Thus, to evaluate the role of the central dopaminergic system in hypothalamic neuronal activation and its relationship with exercise performance, Wistar rats were intracerebroventricularly injected with saline (SAL) or SCH-23390 (SCH, dopamine D1 receptor blocker) at rest and before timed submaximal exercise (∼13 min) or exercise until fatigue. Core body and tail temperatures were recorded throughout the exercise.

Introduction: Since mechanical thrombectomy has allowed ischemic stroke thrombi retrieval, its exhaustive study has involved a better knowledge of physiopathological processes implied in its formation.

Development: Thrombotic pathways involved in the different vascular beds shared common mechanisms conditioning difficulties in the identification of specific patterns associated with stroke etiology. Other factors as clot formation time, associated inflammatory status or activation of additional immune and coagulation pathways [Neutrophil extracellular traps (NETs) delivery, platelet aggregation, endothelial activation and VonWillebrand Factor release] have been described as determinants in thrombus characteristics.

Purpose: To generate consensus and provide expert clinical practice statements for the management of adult sepsis in resource-limited settings.

Methods: An international multidisciplinary Steering Committee with expertise in sepsis management and including a Delphi methodologist was convened by the Asia Pacific Sepsis Alliance (APSA). The committee selected an international panel of clinicians and researchers with expertise in sepsis management.

Purpose: We compared the immediate and sustained effects of 500 mL of crystalloid administered at slow (333 mL/h) versus fast rates (999 mL/h) on mean arterial pressure (MAP) in critically ill patients.

Materials And Methods: Hemodynamic variables were collected immediately before and every 30 min up to 60 min after the end of the infusion. The primary outcome was the adjusted difference in MAP.
