Patients with major depressive disorder (MDD) usually suffer from altered cognitive functions of episodic memory, working memory, mental processing speed and motor response. Diverse studies suggest that different antidepressant agents may improve cognitive functions in patients with MDD. The aim of this work is to study the effects of serotonergic reuptake(More)
INTRODUCTION Cognitive disturbances in Major Depressive Disorder (MDD) could persist beyond the symptomatic phase of the illness. However, the works addressing this topic did not usually account for the possible impact of medication on the cognitive functions of depressed patients. The present study aims to investigate whether MDD patients in remission(More)
Several reports suggest that antidepressants may improve cognitive functioning in patients with major depressive disorder (MDD). The present work aims to study the effects of selective serotonin reuptake inhibitors (SSRIs) and serotonergic-noradrenergic reuptake inhibitors (SNRIs) treatments on the performance of working memory, attention and executive(More)
To examine the effects of avocado on plasma lipid concentrations, a three-diet trial involving 16 healthy volunteers was carried out. A diet rich in monounsaturated fatty acids using avocado as their major source (30% of the total energy was consumed as fat: 75% of the total fat from the avocado), with restriction of saturated fats and less than 300 mg of(More)
INTRODUCTION Major depressive disorder (MDD) is treated with antidepressants, but only between 50% and 70% of the patients respond to the initial treatment. Several authors suggested different factors that could predict antidepressant response, including clinical, psychophysiological, neuropsychological, neuroimaging, and genetic variables. However, these(More)
Cognitive effects of antidepressants and cognitive predictors of antidepressant treatment response are recent focuses of interest in the neuropsychology of depression. We studied the cognitive predictors of treatment response to bupropion and its neuropsychological effects in patients with major depressive disorder. Twenty subjects meeting the DSM-IV(More)
OBJECTIVE The aim of this study was to compare preemptive analgesia of oral ketorolac plus submucous local placebo with oral ketorolac plus submucous local tramadol after impacted mandibular third molar surgery. STUDY DESIGN A double-blind, randomized, placebo-controlled clinical trial was conducted. Patients were randomized into two treatment groups (n =(More)
To determine the effects of a vegetarian diet with avocado as a source of monounsaturated fat on serum lipids, thirteen patients with phenotype II (twelve with IIa and one with IIb) dyslipidemia were included in a prospective, transversal and comparative study in which three four-week diets randomly assigned were assessed. One vegetarian diet (ALVD) was(More)
OBJECTIVE The objective of this study was to investigate the effect of bromocriptine (BEC) on left ventricular mass index (LVMI) and residual renal function (RRF) in chronic kidney disease (CKD) patients with type 2 diabetes (T2D). RESEARCH DESIGN AND METHODS A 6-month double-blind randomized controlled trial was conducted in 28 patients with T2D and(More)
BACKGROUND The prediction of remission in pharmacologically-treated MDD patients has been scarcely studied. The goal of our work is to study the possible effect of clinical variables, neuropsychological performance, and the 5HTTLPR, the rs25531 of the SLC6A4 gene, and the val108/58Met of the COMT gene polymorphisms on the prediction of the speed of(More)
