ABSTRACT
BACKGROUND & AIMS: Liver stiffness measurement by transient elastography (TE) is a promising method for staging fibrosis in alcohol-related liver disease, but uncertainties remain regarding the influence of alcohol consumption and thus the ideal timing for TE performance. We evaluated the performance of TE compared with liver biopsy to exclude compensated advanced chronic liver disease (cACLD) in patients hospitalized for alcohol detoxification. METHODS: Patients were recruited prospectively at 6 in-patient addiction centers in France. Eligible patients had increased aspartate aminotransferase levels, and no history or signs of overt cirrhosis. TE, histology, and biochemistry measurements were obtained within a median of 6 days after alcohol withdrawal. TE and biochemistry were repeated 1 and 2 months later. RESULTS: The study included 259 patients for per-protocol analysis, of whom 45 (17%) had cACLD. TE identified patients with high accuracy at inclusion and at the 1- and 2-month follow-up evaluation, with area under the curve values of 0.96 (95% CIs, 0.94-0.99), 0.96 (95% CIs, 0.92-0.99), and 0.93 (95% CIs, 0.85-1.00), respectively. In 84% of patients, cACLD was ruled out when liver stiffness was less than 10 kPa (negative predictive value, 99% (95% CIs, 98%-100%)) or ruled in when greater than 25 kPa (positive predictive value, 93% (95% CI, 83%-102%)). Algorithms based on aminotransferase levels and/or bilirubin did not add to the diagnostic performance of TE in this period. Among patients with initial liver stiffness of 10 to 25 kPa, more than half of those with no cACLD showed liver stiffness of less than 10 at 1- and 2-month follow-up testing. CONCLUSIONS: TE performed during the first 2 months after alcohol cessation is an excellent method for excluding alcohol-related cACLD. CLINICAL TRIAL NUMBER: NCT01789008.

BACKGROUND: Simulations in healthcare reproduce clinical situations in stressful conditions. Repeated stress exposure might influence the learning process in simulation as well as real-life. OBJECTIVES: 1) To record heart rate and heart rate variability evolution during one-day simulation over one year; 2) To analyze the effect of repetitive high-fidelity simulations on the risk of post-traumatic stress disorder. STUDY DESIGN: Single-center, investigator-initiated RCT. 48 participants were randomized in 12 multidisciplinary teams of French Emergency Medical Services to manage infant shock in high-fidelity simulations. In the experimental group, 6 multidisciplinary teams were exposed to 9 different simulation sessions over 1 year. In the control group, 6 multidisciplinary teams participated in only 3 simulation sessions, in common with those of the experimental group (initial, intermediate after 6 months, and finally after 1 year). Heart rate (HR) and heart rate variability (HRV) were analyzed on a 24-hour Holter from the day prior to simulation until the end of simulation. Questionnaires of Impact of Event Scale-Revised at 7 days and Post-traumatic Check-List Scale at 1 month were used to detect possible post-traumatic stress disorder in participants. p<0.05 was considered significant. RESULTS: Stress increased during each simulation in the two groups. After analysis on the 24-hour period, there was no significant difference between the two groups during the initial simulation session in terms of heart rate and heart rate variability. In the 24-hour period of the intermediate and final simulation sessions, the level of stress was higher in the control group during the diurnal (p = 0.04) and nocturnal periods (p = 0.01). No participant developed post-traumatic stress disorder after the 72 simulation sessions. CONCLUSIONS: Despite the stress generated by simulation, the more the sessions were repeated, the less were their repercussions on the daily lives of participants, reflected by a lower sympathetic activity. Moreover, repetition of simulations did not lead to post-traumatic stress disorder. TRIAL REGISTRATION: ClinicalTrials.gov NCT02424890.

INTRODUCTION: Following the Xynthia storm of February 2010 in France, an outreach program was initiated by the regional health authorities during the post-emergency phase to improve access to mental health care for the population exposed to the floods. The program was designed to complement routine health and social care services. It relied on a special telephone service and outreach consultations located in the town halls of the five most affected cities. The objective of this outreach service was to provide initial psychological counseling free of charge and without appointment. Another objective was to refer persons for appropriate treatment and follow-up by routine health care services. A surveillance program was developed to monitor the use of mental health services by first-time users, describe outreach service users with psychological manifestations, and provide timely information to decision makers. METHODS: Health providers working in affected towns were asked to complete an individual record sheet for each person who displayed psychological manifestations directly or indirectly linked with the storm on their first visit, and to send it to the regional health office. Participation was voluntary. Data analysis was performed monthly during the six-month surveillance period. RESULTS: Only mental health providers participated in the surveillance. A total of 227 individual files were sent from April 7 through September 19, 2010. New cases were mainly female adults, and one fifth had a past history of psychiatric illness. Depressive signs and anxiety were the most commonly reported symptoms, followed by signs of post-traumatic stress disorder. A total of five feedback reports were produced for surveillance participants (informants) and authorities. CONCLUSION: With initiation in the post-emergency phase of a disaster and timely regular feedback, the surveillance program enabled the authors to describe the occurrence of psychological distress, monitor mental health service use by first-time users, and provide guidance to health authorities. This research showed the advantages of integrating epidemiology in the development of strategy for mental health and psychosocial support in the aftermath of natural catastrophes.

The relationships between obstructive sleep apnoea syndrome (OSAS) and stroke are still under discussion, but increasing evidence demonstrates that the OSAS is an independent risk factor for stroke. However, in rare cases, OSAS could be a consequence of strokes, especially if located in the brainstem. Many recent studies have found a 70 to 95% frequency of OSAS (defined by an apnoea/hypopnoea index >10) in patients with acute stroke. Age, body mass index, diabetes, and severity of stroke have been identified as independent predictors of stroke. Furthermore, the presence of OSAS in stroke patients could lead to a poor outcome. The potential mechanisms linking OSAS and stroke are probably multiple (arterial hypertension, cardiac arrhythmia, increased atherogenesis, coagulation disorders, and cerebral haemodynamic changes). Despite numerous uncertainties, OSAS should be systematically screened at the moment it is clinically suspected in patients with acute stroke. However, the optimal timing (early or differed) for treatment with nasal continuous positive airway pressure remains to be determined.
