Venous thromboembolism prophylaxis in a general hospital.

Objective: To evaluate the use of venous thromboembolism (VTE) prophylaxis in a general hospital.

Methods: A cross-sectional cohort study at the Hospital Nossa Senhora da Conceição, located in the city of Porto Alegre, Brazil, involving a random sample of patients admitted between October of 2008 and February of 2009. We included patients over 18 years of age and hospitalized for more than 48 h.

Behavioral and cognitive profile of mice with high and low exploratory phenotypes.

Temperament is the heritable and relatively stable pattern of basic emotions, such as fear and anger. We explored behavioral features in mice to select distinct phenotypes with extremes of temperament. In a new environment (open-field) with a central object, two groups of 15 mice from 79 screened were separated according to high or low exploration of the object to compose the high and low exploratory groups, respectively.

Atypical antipsychotic profile of flunarizine in animal models.

Rationale: Flunarizine is known as a calcium channel blocker commonly used in many countries to treat migraine and vertigo. Parkinsonism has been described as one of its side-effects in the elderly, which is in agreement with its recently characterized moderate D2 receptor antagonism.

Objectives: To perform a pre-clinical evaluation of flunarizine as a potential antipsychotic.
