The role of cognition in vocational functioning in schizophrenia

Schizophrenia is associated with long-term unemployment. Cognitive dysfunction, rather than clinical symptoms, may be the most important factor in the ability to work for patients with this disorder. To evaluate the relationship of clinical symptoms and cognitive functioning to work status, thirty patients with schizophrenia, who were participants in a vocational rehabilitation program, were evaluated with a comprehensive neuropsychological battery and assessment of psychopathology. Subjects were classified as being in stable full-time, part-time or unemployed work status for at least a year. Univariate analysis indicated that patients who were working full-time were significantly better educated, more likely to be treatment-resistant, more likely to be treated with an atypical antipsychotic medication, had more positive symptoms, and were engaged in work tasks which were more cognitively complex than the part-time employed and unemployed work groups. An ANCOVA controlling for education demonstrated that the full-time employed group performed significantly better than the unemployed group on measures of executive functioning, working memory and vigilance; and significantly better than the part-time group on measures of vigilance and executive functioning. Although negative symptoms did not significantly relate to work status in the univariate analysis, a multiple regression indicated that negative symptoms, level of education, and executive functioning differentiated the work groups. These results suggest that poor premorbid function, negative symptoms and cognitive dysfunction are significantly associated with unemployment in schizophrenia.     

A placebo controlled, double-blind study of mecamylamine treatment for cocaine dependence in patients enrolled in an opiate replacement program.

A placebo controlled, double-blind trial of mecamylamine treatment of cocaine dependence was performed in methadone or LAAM maintained subjects who met DSM-IV criteria for cocaine dependence. After an eight-week placebo run-in screening period, 35 subjects were randomly assigned to receive either mecamylamine (6 mg/day) or placebo transdermal patches for a 16-week treatment period. Outcome measures included quantitative urine benzoylecognine (BE) levels, self-report of cocaine use, cocaine craving, global impression scores, mood, retention, and safety. Mecamylamine was well tolerated, and study retention did not differ by treatment group. Evidence for cocaine use, based on urine BE levels and cocaine abstinence rates, did not differ by treatment group. Self reported cocaine use, cocaine craving, and global impression scores showed moderate improvement in both groups, with a significantly greater reduction in cocaine craving (p < 0.05) and self-rated severity of cocaine dependence (p < 0.05) in the placebo group. This pilot study does not support the effectiveness of mecamylamine for the treatment of cocaine dependence in methadone or LAAM maintained patients.     

Clinical Utility and Outcome Prediction of Early ZnT8-IgG Testing and Titer in Type 1 Diabetes

Objective:Type 1 diabetes autoantibodies are directed against multiple antigens including: glutamic acid decarboxylase, protein tyrosine phosphatase-like islet antigen 2 (IA2), insulin (IAA), and Zinc transporter 8 protein (ZnT8). The aim of our study was to determine if the presence or titer of ZnT8 antibodies (Ab) was predictive for clinical presentation at diagnosis or for the subsequent disease course.Methods:Between January, 2003 and May, 2019, 105 patients aged ≤21 years with a clinical diagnosis of type 1 diabetes mellitus had at least 1 autoantibody measured. A retrospective chart review was completed. At diagnosis, we evaluated the body mass index z-score, hemoglobin (HbA1c), and the presence of diabetic ketoacidosis (DKA). Complications analyzed post-diagnosis included episodes of DKA, the diagnosis of autoimmune disease, and the presence of vascular complications. We evaluated cumulative lifetime excess glucose as HbA1c area under the curve (AUC) >6%.Results:Seventy-one patients were ZnT8-Ab(+) (68%), with 19 having low titer ZnT8-Ab and 52 with high titer ZnT8-Ab. Follow-up ranged from 10 days to 15.7 years (median 2.08 years). There were no differences in the characteristics at disease onset or in the subsequent follow-up between those with and those without ZnT8-Ab or those with high or low titers of ZnT8 Ab, except for a small but statistically significant difference in cumulative excess glucose (HbA1c AUC >6%) between those with low and high titers (p=0.0095).Conclusion:Our study adds to the limited literature on the effect of the presence and titer of ZnT8-Ab in pediatric diabetes. The small effect of ZnT8-Ab titer on glucose excess as measured by HbA1c AUC warrants further study.     

Videotapes and multiple interviews: The effects on the child witness

Because of perceived disadvantages of multiple interviews, it has been proposed that the evidence‐in‐chief of child witnesses be given via a videotape made at their first and only interview. However, the child may still be required to face cross‐examination in court having presented their evidence on only one previous occasion. These changes overlook the potential benefits multiple interviews can have on memory for events, particularly given the delays faced by most courts. This paper deals with memory researth which is relevant to this debate, with a particular focus on the phenomenon of reminiscence (remembering previously unrecallable information). The implications of this research forgathering and presenting evidence are discussed.     

Chasing the rainbow: pleasure,sex-based sociality and consumerism in navigating and exiting the Irish Chemsex scene

Club drug use among gay, bisexual and other men who have sex with men is increasingly normalised within sexual contexts and is associated with increased sexual risk behaviours. The term Chemsex is used to describe sexualised drug use lasting several hours or days with multiple sexual partners. A small pilot study, underpinned by interpretative phenomenological analysis (IPA), was conducted in Dublin, Ireland. Interviews were conducted with 10 men who were experiencing physical and emotional health problems as a consequence of their participation in sexualised drug use and wished to exit the Chemsex scene. Interviews explored experiences of sexualised drug use, motives to partake, the organisation of Chemsex parties and group connectivity, drugs used, harm reduction, pleasure and consequences of participation over time. Four basic themes emerged from the analysis: social and cyber arrangements within the Dublin Chemsex scene; poly drug use and experiences of drug dependence; drug and sexual harm reduction within the Chemsex circle of novices and experts; and sexualised drug use, escapism and compulsive participation. Two higher-order themes were also apparent: first, the reinforcing aspects of drug and sexual pleasure; and second, the interplay between excess drug consumption and sex, and drug dependence.
