This study examined the reliability and predictive validity of electronic monitoring (EM) in assessing the oral antipsychotic medication adherence of outpatients with schizophrenia or schizoaffective disorder. Sixty-one adult outpatients with schizophrenia or schizoaffective disorder who took a single oral antipsychotic medication were assessed monthly over a 6-month study period with EM of medication bottle opening. Symptom severity, as measured by the Positive and Negative Syndrome Scale (PANSS) total score, was assessed monthly over the 6-month study period. Cronbach's coefficient alpha revealed very high internal reliability (alpha=0.94). A high degree of test-retest reliability was found (beta ranged from 0.75 to 1.19 and r ranged from 0.63 to 0.90). As for predictive validity, greater mean EM adherence was significantly related to lower mean symptom severity.

Real-World Effectiveness of Long-Acting Injectable and Oral Antipsychotic Agents in US Medicare Patients with Schizophrenia.

Introduction: Daily oral antipsychotics (OAPs) are the mainstay of schizophrenia treatment; however, long-acting injectable antipsychotics (LAIs) are associated with better treatment adherence and improved outcomes.
Methods: This study assessed the real-world comparative effectiveness of LAIs and daily OAPs using claims data from a nationally representative sample of fee-for-service Medicare beneficiaries with schizophrenia. Antipsychotic discontinuation, psychiatric hospitalization, and treatment failure were compared relative to different reference groups using within-individual Cox regression models.

Schizophrenia (SZ) is a deleterious brain disorder characterised by its heterogeneity and complex symptomatology consisting of positive, negative and cognitive deficits. Current antipsychotic drugs ameliorate the positive symptomatology, but are inefficient in treating the negative symptomatology and cognitive deficits. The neurodevelopmental glutamate hypothesis of SZ has opened new avenues in the development of drugs targeting the glutamatergic system.

The objective of this study was to evaluate the therapeutic effects of Chiglitazar combined with Rosa roxburghii Tratt (RRT) in inpatients diagnosed with psychiatric disorders and antipsychotic-induced metabolic syndrome (MetS).100 cases were included and divided into the Siglitazar group (n=50) and the Siglitazar + RRT group (n=50) Anthropometric measurements, lipid and glucose metabolism indicators, inflammatory markers and PANSS scores were assessed at baseline, 8 weeks and 12 weeks post-treatment. Both treatment groups exhibited significant reductions in waist circumference and improvements in lipid profiles and glucose metabolism indicators over the 12-week study period.
