“…The male predominance thus seems to reflect a gender bias in health‐seeking behavior in this ethnic group. However, this is not unique to our sample as the majority of genetic and treatment studies in schizophrenia show a male predominance (Derks, Allardyce, & Boks, ; Huang, Tsai, & Hwub, ). The reasons for this are unclear, but we hypothesize that it may reflect wider societal bias in response to psychosis in men and women and the subsequent impact on health‐seeking pathways.…”

Suicide risk behavior is a significant contributor to the mortality and morbidity of schizophrenia. We previously reported affected sibship status in a Xhosa schizophrenia or schizoaffective disorder sample to be protective in nature; given the counterintuitive nature of this finding, we expanded the sample size to seek further clarification. Subjects were assessed with the Diagnostic Interview for Genetic Studies and then stratified into two groups: with (n = 137) or without (n = 837) a previous suicide attempt. The presence of lifetime bizarre behavior (OR 1.5; 95% CI 1.12-1.87) or cannabis use or abuse (OR 1.2; 95% CI 10.01-1.47) was a significant predictor of suicide attempts, while a higher global alogia score (OR 0.84; 95% CI 0.74-0.96) was a protective factor. Our data seem to support that in this population, encouraging family members to report bizarre behavior and implementing dual diagnosis interventions for cannabis use or abuse could be an appropriate starting point toward developing a targeted suicide prevention program for further research.

The label switching problem occurs as a result of the nonidentifiability of posterior distribution over various permutations of component labels when using Bayesian approach to estimate parameters in mixture models. In the cases where the number of components is fixed and known, we propose a relabelling algorithm, an allocation variable-based (denoted by AVP) probabilistic relabelling approach, to deal with label switching problem. We establish a model for the posterior distribution of allocation variables with label switching phenomenon. The AVP algorithm stochastically relabel the posterior samples according to the posterior probabilities of the established model. Some existing deterministic and other probabilistic algorithms are compared with AVP algorithm in simulation studies, and the success of the proposed approach is demonstrated in simulation studies and a real dataset.

“…12 However, the florid psychotic symptoms at admission usually regress somewhat after treatment and therefore do not provide enough information about longterm outcome, 9 and a substantial proportion of patients in the subgroups with acute symptoms would be categorized into other subgroups when symptoms are not acute. 13 Symptomatology at discharge from the hospital is also a poor predictor because the time of discharge is biased by service availability. 14 Although the nature of schizophrenia subtypes and their correlations to outcomes are complex, 12,15e17 the symptom profile assessed 3 to 6 months after acute treatment was a better reference to predict future course and outcome.…”
