AI Article Synopsis
- - The study investigates the connection between low handgrip strength (HGS), HGS asymmetry, cognitive performance, and psychotic symptoms in hospitalized schizophrenia patients, aiming to validate HGS as a measure for cognitive and psychotic assessment.
- - A total of 235 inpatients were tested; low HGS was defined as below certain weight thresholds, and asymmetric HGS was indicated by specific ratios, with assessments done using the MoCA-C and PANSS scales.
- - Results indicated a significant link between low HGS (and HGS asymmetry) to lower cognitive scores and higher psychotic symptom scores, suggesting that screening for HGS could help identify patients needing additional cognitive and psychotic evaluations.
Article Abstract
Background And Objectives: A correlation between low handgrip strength (HGS), HGS asymmetry, and low cognitive performance has been demonstrated. However, it remains unclear whether low HGS is associated with psychotic symptoms and whether HGS asymmetry is associated with cognitive and psychotic symptoms in hospitalized patients with schizophrenia. This study aimed to investigate the validity of HGS as a measure for assessing cognition and psychotic symptoms in hospitalized patients with stable schizophrenia.
Methods: A total of 235 inpatients with stable schizophrenia were recruited between August 1, 2023, and August 31, 2023. The highest HGS values from three tests on the dominant hand were used to determine low HGS (male < 28 kg, female < 18 kg), and HGS asymmetry was identified when the non-dominant HGS/dominant HGS ratio was outside 0.9-1.1. Cognition and psychotic symptoms were assessed using the Chinese Montreal Cognitive Assessment (MoCA-C) and Positive and Negative Syndrome Scale (PANSS). Generalized linear model analyses examined the relationship between HGS and scale scores.
Results: Covariate-adjusted generalized linear models confirmed a strong association between low HGS alone and the MoCA-C score (OR = 0.819, 95% CI = 0.710‒0.945, p = 0.006) and PANSS score (OR = 1.113, 95% CI = 1.036‒1.239, p = 0.006). Similarly, the combination of low and asymmetric HGS was strongly associated with both MoCA-C (OR = 0.748, 95% CI = 0.653‒0.857, p<0.001) and PANSS scores (OR = 1.118, 95% CI = 1.032‒1.211, p = 0.006).
Conclusions: The results suggest that hospitalized patients with schizophrenia and low HGS, with or without asymmetry, are likely to have lower MoCA-C scores and higher PANSS scores. Screening stable schizophrenia patients with low HGS, with or without asymmetry, could be a valuable and straightforward approach to identifying those with lower cognition and severe psychotic symptoms.

Introduction: Although maintenance treatment is recommended for the prevention of relapse, in real-world settings, a subset of patients discontinue antipsychotics while having a good prognosis. The prediction of functional remission in patients with schizophrenia after antipsychotic discontinuation (FURSAD) study aims to obtain real-world knowledge regarding the characteristics of schizophrenia (SCZ) patients who achieve functional remission after antipsychotic discontinuation for 1 year or more. This study also aims to establish a prediction model to identify patients likely to benefit from antipsychotic discontinuation.

Gut microbial dysbiosis or altered gut microbial consortium, in schizophrenia suggests a pathogenic role through the gut-brain axis, influencing neuroinflammatory and neurotransmitter pathways critical to psychotic, affective, and cognitive symptoms. Paradoxically, conventional psychotropic interventions may exacerbate this dysbiosis, with antipsychotics, particularly olanzapine, demonstrating profound effects on microbial architecture through disruption of bacterial phyla ratios, diminished taxonomic diversity, and attenuated short-chain fatty acid synthesis. To address these challenges, novel therapeutic strategies targeting the gut microbiome, encompassing probiotic supplementation, prebiotic compounds, faecal microbiota transplantation, and rationalised co-pharmacotherapy, show promise in attenuating antipsychotic-induced metabolic disruptions while enhancing therapeutic efficacy.

Introduction: Ambulance staff play a crucial role in responding to mental health crises. However, negative regard toward patients with mental health conditions can hinder care. The Medical Condition Regard Scale (MCRS) assesses regards or attitudes but has not previously been validated for educated ambulance staff and has never been translated into Norwegian.
