Chronic tobacco consumption, classified as tobacco use disorder (TUD), has been associated with a variety of health problems. Investigations of face processing in TUD are hampered by lack of evidence. Here, we evaluated facial detection in TUD and assessed test-retest reliability for a facial detection task.

Participants were instructed to detect the orientation (either left or right) of a face when it was presented with a face/non-face pair on the monitor screen, using Bayesian entropy estimation. Bland-Altman analysis and intraclass correlation coefficients were used to test the reliability of the task. The general linear model and Bayesian statistics were then used to evaluate differences between TUD (n=48) and healthy controls (n=34).

The reliability of the task was high for the 96 stimuli presentations. Slower reaction times (p < 0.001) and lower discrimination index (p < 0.001) were observed in the TUD group than for healthy controls. Mediation analysis indicated direct effects of smoking duration on reaction time (p < 0.001) and discrimination index (p < 0.001).

Overall, we observed high reliability of this task and reduction of facial detection in tobacco use disorder. We conclude our findings are significant for public health initiatives and call for follow-up studies.

To grade the evidence about risk factors for eating disorders (anorexia nervosa, bulimia nervosa, and binge eating disorder) with an umbrella review approach.

This was a systematic review of observational studies on risk factors for eating disorders published in PubMed/PsycInfo/Embase until December 11th, 2019. We recalculated random-effect meta-analyses, heterogeneity, small-study effect, excess significance bias and 95% prediction intervals, grading significant evidence (p < 0.05) from convincing to weak according to established criteria. Quality was assessed with the Assessment of Multiple Systematic Reviews 2 (AMSTAR-2) tool.

Of 2,197 meta-analyses, nine were included, providing evidence on 50 risk factors, 29,272 subjects with eating disorders, and 1,679,385 controls. Although no association was supported by convincing evidence, highly suggestive evidence supported the association between childhood sexual abuse and bulimia nervosa (k = 29, 1,103 cases with eating disorders, 8,496 controls, OR, 2.73, 95%CI 1.96-3.79, p = 2.1 x 10-9, AMSTAR-2 moderate quality) and between appearance-related teasing victimization and any eating disorder (k = 10, 1,341 cases with eating disorders, 3,295 controls, OR 2.91, 95%CI 2.05-4.12, p = 1.8x10-9, AMSTAR-2 moderate quality). Suggestive, weak, or no evidence supported 11, 29, and 8 associations, respectively.

The most credible evidence indicates that early traumatic and stressful events are risk factors for eating disorders. Larger collaborative prospective cohort studies are needed to identify risk factors for eating disorders, particularly anorexia nervosa.

Longitudinal measurement invariance analyses are an important way to assess a test's ability to estimate the underlying construct over time, ensuring that cognitive scores across visits represent a similar underlying construct, and that changes in test performance are attributable to individual change in cognitive abilities. https://www.selleckchem.com/products/sy-5609.html We aimed to evaluate longitudinal measurement invariance in a large, social and culturally diverse sample over time.

A total of 5,949 participants from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) were included, whose cognition was reassessed after four years. Longitudinal measurement invariance analysis was performed by comparing a nested series of multiple-group confirmatory factor analysis models (for memory and executive function factors).

Configural, metric, scalar and strict invariance were tested and supported over time.

Cognitive temporal changes in this sample are more likely to be due to normal and/or pathological aging. Testing longitudinal measurement invariance is essential for diverse samples at high risk of dementia, such as in low- and middle-income countries.

Although the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) includes ancillary symptom dimensions - insight, avoidance, degree of indecisiveness, inflated sense of responsibility, pervasive slowness/disturbance of inertia, and pathological doubting -, we know little about their clinical/scientific utility. We examined these ancillary dimensions in childhood obsessive-compulsive disorder (OCD), and tested their associations with clinical characteristics.

Treatment-seeking children and adolescents (n=173) with a DSM-5 OCD diagnosis were recruited from six centers in India and evaluated with a semi-structured proforma for sociodemographic/clinical details, the Structured Clinical Interview for DSM-5, the CY-BOCS, the Children's Depression Rating Scale, and the Family Interview for Genetic Studies. Regression analysis was used to study the associations between ancillary dimensions (independent variables) and clinical variables (dependent variables).

87.9% of the sample reported at least a mild-moderate severity of ancillary dimensions, which were highly intercorrelated. Multiple ancillary dimensions were correlated with illness severity on the CY-BOCS. On regression analysis, only insight and avoidance retained significance. There were few differential associations between OCD symptom and ancillary dimensions.

Ancillary dimensions are more a feature of illness severity than differentially associated with individual symptom dimensions in childhood OCD. Insight and avoidance should be considered for inclusion in the assessment of illness severity in childhood OCD.
