Childhood trauma and emotional processing circuits in schizophrenia: A functional connectivity study.

Childhood trauma strongly impacts emotional responses in schizophrenia. We have explored an association between early trauma and the amygdala functional connectivity using generalized psychophysiological interaction during an emotional task. Twenty-one schizophrenia patients and twenty-five controls were included.

Neurobehavioral and Cognitive Changes Induced by Hypoxia in Healthy Volunteers.

The early assessment of new symptomatic drugs against Alzheimer's disease remains difficult because of the lack of a predictive end-point. The use of a battery including different parameters could improve this early development. In order to test the reverse effect of symptomatic drugs in healthy volunteers, scientists have developed new experimental paradigms to artificially induce transient cognitive impairments in healthy volunteers akin to those observed in Alzheimer's disease, i.

Childhood neglect predicts disorganization in schizophrenia through grey matter decrease in dorsolateral prefrontal cortex.

Objective: Psychosocial trauma during childhood is associated with schizophrenia vulnerability. The pattern of grey matter decrease is similar to brain alterations seen in schizophrenia. Our objective was to explore the links between childhood trauma, brain morphology and schizophrenia symptoms.

Severe decrease of cyclosporine levels in a heart transplant recipient receiving the direct thrombin inhibitor argatroban.

This case report is about a suspected interaction between argatroban, a direct thrombin inhibitor, and cyclosporine, which occurred in a 60-year-old patient after a second heart transplantation. We explored 4 possible mechanisms of interaction, which are an analytical interference, an idiopathic hemodilution, an increase of renal and hepatic clearance, and a metabolic drug-drug interaction.

Attentional bias in post-traumatic stress disorder diminishes after symptom amelioration.

Background: Avoidance and hypervigilance to reminders of a traumatic event are among the main characteristics of post-traumatic stress disorder (PTSD). Attentional bias toward aversive cues in PTSD has been hypothesized as being part of the dysfunction causing etiology and maintenance of PTSD. The aim of the present study was to investigate the cognitive strategy underlying attentional bias in PTSD and whether normal cognitive processing is restored after a treatment suppressing core PTSD symptoms.

Amygdala activity correlates with attentional bias in PTSD.

Post-traumatic stress disorder (PTSD) is an anxiety disorder arising in the aftermath of a traumatic event. The most prevalent hypothesis is that of an increased amygdala activity to threat cues. The amygdala has also shown an implication in orienting attention toward threat.

High plasma ropivacaine concentrations after fascia iliaca compartment block in children.

Background: The pharmacokinetic profile of local anaesthetics is influenced by the mode of administration. We sought to compare the pharmacokinetics of two doses of ropivacaine after fascia iliaca compartment (FIC) block in children.

Methods: In this prospective, double-blind study, children received an FIC block as a part of their anaesthetic management during elective orthopaedic surgery on the thigh.
