Patients' Comprehension of Mindfulness-Based Cognitive Behavioral Therapy in an Outpatient Clinic for Resistant Depression: A Cross-Sectional Study.

The current study investigated the comprehension of mindfulness-based cognitive behavioral therapy (MBCT) by patients with resistant depression at the Psychiatry Institute of the Federal University of Rio de Janeiro, Brazil. This was the first time the model was used in the institution to treat these patients. In this study, 45 patients were invited to participate in a baseline session of MBCT that consisted in the explanation of the model and experimental exercises conducted by two experienced therapists.

Prenatal undernutrition changes renovascular responses of nimesulide in rat kidneys.

Several studies in the Northeastern region of Brazil have demonstrated an association between hypertension in adult populations and prenatal and postnatal undernutrition. The central hypothesis we proposed was that hypertension could be favoured by programmed alterations in branches of the renal arachidonic pathway and consequently in counter-balancing the renin angiotensin system, especially during treatments with cyclooxygenase inhibitors. We assessed the influence of subchronic (21 days) and acute administration of nimesulide, a preferential cyclooxygenase-2 (COX-2) inhibitor, on mean blood pressure (MAP), renal blood flow (RBF), glomerular filtration rate (GFR) and urinary output (U(v)) in adult rats that were prenatally undernourished.

Repercussion of acetylsalicylic acid during fetal development on later renal hemodynamics of rats.

Acetylsalicylic acid (ASA) during pregnancy reaches the fetus. It seems important to know possible repercussions of ASA on later renal function of the offspring, as well as repercussions of this drug on factors that may influence fetal development, such as maternal plasma volume and placental oxidative stress. It was evaluated whether ASA changes maternal plasma volume and/or placental oxidative stress, fetal weight and renal function of the offspring at adult life.
