Abstract
OBJECTIVE To identify risk factors for perioperative morbidity among a large national cohort of pediatric patients undergoing cochlear implantation. STUDY DESIGN Retrospective study utilizing the American College of Surgeons National Surgical Quality Improvement Program Pediatric database (2012-2013). METHODS Pediatric cochlear implantation cases were identified using current procedural terminology 69930. Patients were categorized by age, and operative characteristics along with 30-day perioperative outcomes were analyzed. RESULTS We identified 1,351 cases of pediatric cochlear implantation. The median age was 3.6 years, and 73 patients were less than 1 year of age. Of 21 complication occurrences (1.55%), superficial incisional surgical site infection (SSI) was the most common (n = 13, 61.9%). Thirty-nine patients (2.9%) required readmission. The median operative time was 142 minutes, and the mean postoperative length of stay was 0.58 days. When comparing patients younger than 1 year old to those 1 year or older, no significant differences were noted in complication rate, postoperative length of stay, or reoperation rate. Patients less than 1 year of age were more likely to be readmitted (6.9% vs. 2.7%, P = 0.04) and had longer mean operative times (191 minutes vs. 160 minutes, P = 0.0015). Steroid use was a risk factor for unplanned reoperation, SSI, and readmission. CONCLUSION Despite a slight increase in readmission rates and operative times among patients less than 1 year of age, cochlear implantation appears to be safe in this population, with complication rates, reoperation rates, and postoperative lengths of stay similar to children undergoing the procedure at the current U.S. Food and Drug Administration-approved age of 1 year and older. LEVEL OF EVIDENCE 4. Laryngoscope, 127:720-724, 2017.

Abstract
OBJECTIVE Data suggest that adherence to religious beliefs is associated with lower rates of suicide. A number of mediating factors have been hypothesized to explain this association, including enhanced social support, less substance abuse, and lower rates of psychopathology. METHOD We utilized data from a two-phase population-based, epidemiological study of mental disorders among young Jewish Israel born in a 10-year birth-cohort conducted in the 1980s. This study included data on religiosity and suicidal behaviour. Twenty-five years thereafter, mortality data were obtained from a national vital statistics registry. RESULTS Rates of suicidal ideation were similar among secular, partially observant, and religious subjects (9.4%, 6.7%, and 6.2%, respectively; adjusted OR for linear trend: 0.80, 95% CI: 0.58-1.09). Rates of suicide attempts were significantly lower among religious subjects (2.4%, 2.5%, and 0.4% for secular, partially observant, and religious, respectively; adjusted OR for linear trend: 0.62, 95% CI: 0.43-0.88). Of the 4914 subjects, eight died by suicide: Seven of them were secular and one was partially observant (χ(2) = 2.52, P = 0.09). There were no differences in social functioning or rates of psychopathology among the study groups. CONCLUSION Religiosity has a protective effect against suicide attempts, which is independent of social functioning, psychopathology, and substance use.

Abstract
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT Low IQ is associated with high BMI in childhood. There are inconsistent findings on the association between low SES and high BMI. Youth with low IQ have been reported to have poorer health behaviors, such as poor nutrition and less physical activity. WHAT THIS STUDY ADDS Low IQ is significantly associated with obesity for both male and female adolescents, though more strongly for female adolescents. Physical activity has a mediating effect on the association between low IQ and obesity among both male and female adolescents, though more strongly for male adolescents. The association between low IQ and obesity is strongest among adolescents from high SES backgrounds. BACKGROUND Previous studies have shown an association between low intelligence quotient (IQ), high body mass index and low socioeconomic status (SES). OBJECTIVES This study examined the cross-sectional association between IQ and obesity, exploring the roles of gender, SES and physical activity in this association. METHODS Subjects were 235,663 male and 169,259 female adolescents assessed by the Israeli military draft board. RESULTS Low IQ was significantly associated with increased odds of obesity among male (odds ratio [OR] = 1.44, 95% confidence interval [CI] = 1.36-1.52) and female adolescents (OR = 1.61, 95% CI = 1.51-1.73); this association was significantly stronger among female adolescents. Sobel tests indicated that physical activity had a significant mediating effect on this association for male and female adolescents, although more strongly for male adolescents. Dividing the sample according to SES, the association between low IQ and obesity was strongest in the high SES group (male adolescents: OR = 1.26, 95% CI = 1.10-1.43, female adolescents: OR = 1.61, 95% CI = 1.38-1.89), even when controlling for physical activity. CONCLUSIONS The findings suggest that low IQ is associated with increased odds of obesity, particularly in female adolescents and in adolescents with high SES. Physical activity has a mediating effect on this association, although more strongly for male than for female adolescents. Public health measures on decreasing obesity might focus on these groups.

Abstract
BACKGROUND Previous studies have found that patients with schizophrenia are more likely to be violent than the general population. The aim of this study was to investigate the association between schizophrenia and violent crime in the Israeli population. METHOD Using the Israeli Psychiatric Hospitalization Case Registry we identified 3187 patients with a discharge diagnosis of schizophrenia. For each proband we identified parents and siblings, and gender- and age-matched controls for patients, parents and siblings. Information on violent crimes was obtained from police records. RESULTS Patients with schizophrenia were at increased risk for violent crimes compared with controls [odds ratio (OR) 4.3, 95% confidence interval (CI) 3.8-4.9], especially women (OR 9.9, 95% CI 6.2-15.7). Risk for violent crimes was higher among patients with co-morbid substance misuse than in patients without such co-morbidity (OR 5.1, 95% CI 4.2-6.3). CONCLUSIONS The results of this study suggest that increased risk of violence is part of the clinical picture of schizophrenia and needs to be recognized as a legitimate, essential, aspect of clinical management.

Abstract
OBJECTIVE To systematically review the evidence for health coaching for patients with low back pain and describe the diversity of health coach training and interventions. METHODS Electronic databases Medline, CINAHL, EMBASE, PsycINFO, AMED and the Cochrane Central Register of Controlled Trials were searched to 24 June 2013 using individually devised strategies. Randomised or quasi randomised controlled trials (RCTs) of health coaching for adults with low back pain of any duration were considered. The overall quality of the body of evidence was assessed using the GRADE approach. Treatment effects were presented as the difference in mean scores with 95% confidence intervals and standardised mean difference at follow-up between health coaching and control groups. Health coaching interventions were compared narratively by their theoretical principles and the training and assessment of heath coaches. RESULTS Five publications describing three RCTs and one cluster RCT met the criteria for review. A rating of very low was assigned to the body of evidence using the GRADE approach. One RCT found significant improvements in lifting capacity and exercise compliance in favour of the health coaching group at both follow-up points with a large and moderate standardised mean difference. All included studies based health coaching interventions on the transtheoretical model of change however, the content of counselling programmes varied between studies and measures of treatment fidelity were inconclusive. DISCUSSION Variability in health coaching interventions and a lack of assessment of treatment fidelity in addition to the very low rating of the overall body of evidence identified in the current review renders any estimates of the effect of health coaching on low back pain uncertain. Well-designed RCTs of patients with sub-acute low back pain are required that incorporate clearly described protocols for health coaching interventions and include standardised measures of treatment fidelity.

Abstract
Patients in Intensive Care Unit (ICU) often require sedatives which commonly include midazolam and the more recently developed α2-receptor agonist, dexmedetomidine. It was our aim to compare the sedative and clinical effectiveness of dexmedetomidine vs midazolam in adults admitted to ICU, using an objective appraisal of randomized control trials. Medline, Embase, SCOPUS, Web of Knowledge, Cinhal, the United States National Library of Medicine, and the Cochrane Database of Systematic Reviews were searched using keywords: 'dexmedetomidine', 'midazolam', and 'intensive care'. These were limited to human studies and adults (>18 yr old). Six randomized controlled trials were found and were critically appraised using a standardized appraisal method. Two papers described the time spent by each intervention group within a specified target sedation range and both found no statistically significant difference between midazolam and dexmedetomidine (P=0.18 and P=0.15). A third paper found no statistically significant difference in the length of time that patients were sedated within a target zone (P=0.445). Two additional pilot studies did not report P values as they were insufficiently statistically powered. A final paper found that, of the eight occasions measured, patients on dexmedetomidine were more often within the target sedation range than patients on midazolam. The sedative benefits of dexmedetomidine vs midazolam remain inconclusive. While some secondary outcomes showed clinical effectiveness of dexmedetomidine, more research is needed to validate the findings of these studies.

Abstract
UNLABELLED Studies and meta-analyses investigating the influence of substance use disorder (SUD) (substance abuse or dependence) on psychopathology and neurocognitive function in schizophrenia patients have revealed controversial results. Most studies did only have small samples and did not focus exclusively on first-episode schizophrenia patients. METHOD In a post-hoc analysis of the European First Episode Schizophrenia Trial (EUFEST) psychopathology and cognitive performances of patients with (FE-SUD, N=119, consisting of N=88 patients with persisting SUD at baseline and N=31 patients with previous SUD) and without SUD (FE-non-SUD, N=204) were compared at baseline and 6 months follow-up. Neurocognitive assessment included the Rey Auditory Verbal Learning Test (RAVLT); Trail Making Tests A and B (TMT), Purdue Pegboard and Digit-Symbol Coding. RESULTS In total 31.1% of patients reported SUD, and 22.2% of patients used cannabis. There were no significant differences between patients with and without SUD concerning PANSS scores, extrapyramidal motor symptoms or neurocognitive measures except better performance in psychomotor speed (TMT-A, p=0.033, Cohen's d=0.26) in patients with SUD at 6 months follow-up. Interestingly, SUD patients with ongoing substance use at follow-up showed elevated positive symptoms (PANSS positive score, p=0.008, Cohen's d=0.84) compared to those who abstained. PANSS scores at baseline were increased in patients with an onset of SUD before the age of 16 years. In addition we found a correlation between longer duration of cannabis use and higher cognitive performance as well as reduced symptom improvement and more extrapyramidal motor symptoms in patients with higher frequency of cannabis consumption. CONCLUSIONS FE-SUD and FE-non-SUD show similar psychopathology and neuropsychological performances at baseline and during the first 6 months of antipsychotic treatment.
