The suprachiasmatic nuclei (SCN) distribute the circadian neural message to the pineal gland which transforms it into a humoral circadian message, the nocturnal melatonin synthesis, which in turn modulates tissues expressing melatonin receptors such as the SCN or the pars tuberalis (PT). Nuclear orphan receptors (NOR), including rorbeta and rev-erbalpha,(More)
OBJECTIVES It remains uncertain whether colonization and infection with ESBL-producing Enterobacteriaceae (ESBL-PE) affect the outcomes for ICU patients. Our objectives were to measure the effects of ESBL-PE carriage and infection on mortality, ICU length of stay (LOS) and carbapenem exposure in this population. METHODS A cause-specific hazard model based(More)
The best renal replacement therapy (RRT) modality remains controversial. We compared mortality and short- and long-term renal recovery between patients treated with continuous RRT and intermittent hemodialysis. Patients of the prospective observational multicenter cohort database OUTCOMEREA™ were included if they underwent at least one RRT session between(More)
A case is reported of a Senegalese patient admitted for hydatiform mole. The serum human chorionic gonadotrophin concentration (hCG) was 900,000 UI.l-1. The patient was recognized to be clinically hyperthyroid with raised T4 and T3 values, but a very low TSH concentration. After two days of beta adrenergic blockade and carbimazole, a suction curettage was(More)

BACKGROUND Convulsive status epilepticus often results in permanent neurologic impairment. We evaluated the effect of induced hypothermia on neurologic outcomes in patients with convulsive status epilepticus. METHODS In a multicenter trial, we randomly assigned 270 critically ill patients with convulsive status epilepticus who were receiving mechanical(More)
To assess the prevalence of decisions to forgo life-sustaining treatment (DFLST), the patients characteristics, and to estimate the impact of DFLST stages on mortality. Observational study of a prospective database between 2005 and 2012 from 13 ICUs. DFLST were defined as follows: no escalation of treatment (stage 1), not to start or escalate treatment even(More)
Few data are available about optimal nutrition modalities in mechanically ventilated patients with shock. Our objective was to assess associations linking early nutrition (<48 h after intubation), feeding route and calorie intake to mortality and risk of ventilator-associated pneumonia (VAP) in patients with invasive mechanical ventilation (IMV) and shock.(More)
PURPOSE Prolonged periods of constant lighting are known to perturb circadian clock function at the molecular, physiological, and behavioral levels. However, the effects of ambient lighting regimes on clock gene expression and clock outputs in retinal photoreceptors--rods, cones and intrinsically photosensitive retinal ganglion cells--are only poorly(More)
The "perioperative" period for elderly patients is prone to a significant level of morbidity and mortality. Chronological age and comorbidities are the main causes of mortality. Loco-regional anaesthesia is used in 50% of cases. When general anaesthesia is used, invasive monitoring is the rule, with titration of medication and pain treatment. Cognitive(More)
