The Psychological Impact on Relatives of Critically Ill Patients: The Influence of Visiting Hours.

Objectives: To identify the psychologic impact of admission to the ICU on the relatives of critically ill patients, the influence of coping, and the factors involved.

Design: We performed a cohort study with repeated measures evaluation using descriptive and comparative bivariate and multivariate analyses.

Settings: An adult ICU of a third-level complexity hospital.

Deep Brain Stimulation of the Nucleus Accumbens, Ventral Striatum, or Internal Capsule Targets for Medication-Resistant Obsessive-Compulsive Disorder: A Multicenter Study.

Background: Deep brain stimulation of the nucleus accumbens, ventral striatum, or internal capsule region has shown a 45%-60% response rate in adults with severe treatment-refractory obsessive-compulsive disorder, regardless of which target is used. We sought to improve the effectiveness of deep brain stimulation by placing the electrode along a trajectory including these 3 targets, enabling a change of stimulation site depending on the patient's response.

Methods: This study used the medical records of 14 patients from 4 different Spanish institutions: 7 from the Hospital Universitario La Princesa, 3 from the Hospital Universitario Central de Asturias, 2 from Hospital Universitario Fundación Jiménez Díaz, and 2 from Hospital Universitari Son Espases.

Deep brain stimulation for aggressiveness: long-term follow-up and tractography study of the stimulated brain areas.

Objective: Initial studies applying deep brain stimulation (DBS) of the posteromedial hypothalamus (PMH) to patients with pathological aggressiveness have yielded encouraging results. However, the anatomical structures involved in its therapeutic effect have not been precisely identified. The authors' objective was to describe the long-term outcome in their 7-patient series, and the tractography analysis of the volumes of tissue activated in 2 of the responders.
