Heterogeneity Among Countries in the Subspecialty of Cardiovascular Anesthesia in Latin America: Survey Results.

Objectives: To evaluate demographics, workload, training, facilities, and equipment in cardiovascular anesthesia (CVA) in Latin America (LA).

Design: A descriptive cross-sectional study with data collected through a survey.

Setting: A multicenter, international web-based questionnaire that included 37 multiple-choice questions.

Inferior vena cava ultrasonography before general anesthesia cannot predict arterial hypotension in patients undergoing vascular surgery.

Introduction: Intraoperative hypotension (IH) is an independent predictor of mortality. Some experts have suggested that ultrasound measurement of the inferior vena cava (IVC) in spontaneous ventilation can predict IH.

Objective: To evaluate the capacity of ultrasound measures of IVC in spontaneous ventilation to predict episodes of IH after anaesthesia induction.

A clustering classification of catchment anthropogenic modification and relationships with floods.

Anthropogenic modifications at catchments scale may be reconducted primarily at soil sealing and streams culverting, even if important consequences result from roads density and, more in general, infrastructures as they cause landscape fragmentation, and agricultural areas extension. Their most important outcomes in terms of hydrologic balance are the decreasing time of concentration and the increasing flood risk at catchment scale. The research introduces a methodological approach to classify the degree of anthropogenic modifications at catchment scale: clustering techniques have been applied to 508 catchments in a high-risk flooding sector of the Mediterranean region.

Neostigmine for the treatment of gastrointestinal atony: a report of one case.

Background: A case of severe constipation is described in a 75-year- old cancer patient receiving methadone for pain. Her constipation was refractory to the current treatment and she suffered severe discomfort and cognitive impairment. Due to the severity of the clinical situation and after excluding mechanical obstruction, low doses of subcutaneous neostigmine were administered, having bowel movements with evacuation of stools in a few hours after its administration.
