Observational Study
Procalcitonin as a prognostic marker for sepsis: a prospective observational study.
Procalcitonin is useful for the diagnosis of sepsis but its prognostic value regarding mortality is unclear. This prospective observational study was designed to study the prognostic value of procalcitonin in prediction of 28 day mortality in patients of sepsis. Fifty-four consecutive patients of sepsis, severe sepsis and septic shock defined using the 2001 Consensus Conference SCCM/ESICM/ACCP/ATS/SIS criteria from medical Intensive Care Unit (ICU) of a tertiary care center in New Delhi, India were enrolled from July 2011 to June 2013. Procalcitonin (PCT), C-reactive protein (CRP) measurements were recorded on day 1, day 7 and day 28 of follow up. ⋯ A Procalcitonin value [greater than or equal to]7 ng/ml obtained at the time of admission to the ICU is a predictor of short-term mortality and thus may allow the identification of those septic patients at increased mortality risk, and help improve their treatment.

Comparative Study
Assessing time to treatment and patient inflow in a Danish emergency department: a cohort study using data from electronic emergency screen boards.
The purpose of this study was to assess and describe the patient inflow during a 1-month period in a Danish emergency department and to evaluate if the intended times to treatment (TTT) related to category of triage were met. ⋯ The results demonstrated varying patterns of patient inflow between weekdays and weekends. There was a significantly increased risk of being attended late when arriving on evenings and nights. Likewise higher acuity was associated with exceeded TTT.

This post hoc analysis assessed the safety, tolerability and effectiveness of long-term treatment with aripiprazole adjunctive to either bupropion or selective serotonin reuptake inhibitors (SSRIs)/serotonin-norepinephrine reuptake inhibitors (SNRIs) in patients with major depressive disorder (MDD). ⋯ There were no unexpected AEs with long-term adjunctive aripiprazole therapy when added to either bupropion or SSRIs/SNRIs, and symptom improvement was similar between ADT groups. Sexual functioning in patients with MDD on antidepressants was also modestly improved after adding aripiprazole.

Wernicke's encephalopathy is an acute neurological disorder resulting from thiamine deficiency mainly related to alcohol abuse. Severe thiamine deficiency is an emerging problem in non-alcoholic patients and it may develop in postoperative surgical patients with risk factors. ⋯ Early detection of subclinical thiamine deficiency is a difficult task, as symptoms may be nonspecific. Wernicke's disease remains a clinical diagnosis because there are no specific diagnostic abnormalities revealed in cerebrospinal fluid, electroencephalogram or evoked potentials. About this, the best aid for a correct diagnosis is the clinical suspicion and clinicians should consider the disorder in any patients with unbalanced nutrition, increased metabolism or impaired food absorption. A hallmark of our case was the brain hemorrhage in the typical areas of the Wernicke's disease, maybe triggered by the thrombocytopenia secondary to sepsis. It might be a good clinical practice administer thiamine to all patients presenting with coma or stupor and risk factors related with thiamine deficiency. Any therapeutic delay may result in permanent neurological damage or death.

The electrical impedance tomography (EIT)-based global inhomogeneity (GI) index was introduced to quantify tidal volume distribution within the lung. Up to now, the GI index was evaluated for plausibility but the analysis of how it is influenced by various physiological factors is still missing. The aim of our study was to evaluate the influence of proportion of open lung regions measured by EIT on the GI index. ⋯ We conclude that the GI index is a reliable measure of ventilation heterogeneity highly correlated with lung recruitability measured with EIT. The GI index may prove to be a useful EIT-based index to guide ventilation therapy.
