AI Article Synopsis
- A study explored the relationship between obesity and schizophrenia, focusing on predicting resting energy expenditure (REE) in Asian patients with schizophrenia on antipsychotics.
- Researchers compared four REE predictive equations to assess their accuracy, involving 110 patients from various psychiatric hospitals.
- Results indicated that the Harris-Benedict equation was the most reliable for estimating REE, while other equations, like those from the FAO/WHO/UNU and Schofield, showed significant overestimations.
Article Abstract
Background: Recently, a relationship between obesity and schizophrenia has been reported. The prediction of resting energy expenditure (REE) is important to determine the energy expenditure of patients with schizophrenia. However, there is a lack of research concerning the most accurate REE predictive equations among Asian patients with schizophrenia. The purpose of the study reported here was to compare the validity of four REE equations for patients with schizophrenia taking antipsychotics.
Methods: For this cross-sectional study, we recruited patients (n=110) who had a Diagnostic and Statistical Manual of Mental Disorders, fourth edition, diagnosis of schizophrenia and were admitted to four psychiatric hospitals. The mean (± standard deviation) age of these patients was 45.9±13.2 years. Anthropometric measurements (of height, weight, body mass index) were taken at the beginning of the study. REE was measured using indirect calorimetry. Comparisons between the measured and estimated REEs from the four equations (Harris-Benedict, Mifflin-St Jeor, Food and Agriculture Organization/World Health Organization/United Nations University, and Schofield) were performed using simple linear regression analysis and Bland-Altman analysis.
Results: Significant trends were found between the measured and predicted REEs for all four equations (P<0.001), with the Harris-Benedict equation demonstrating the strongest correlation in both men and women (r=0.617, P<0.001). In all participants, Bland-Altman analysis revealed that the Harris-Benedict and Mifflin-St Jeor equations did not show a significant bias in the prediction of REE, however, a significant overestimation error was shown for the Food and Agriculture Organization/World Health Organization/United Nations University and Schofield equations.
Conclusion: When estimating REE in patients with schizophrenia taking antipsychotics, the Harris-Benedict equation appears to be the most appropriate for clinical use.

Background: People with an intellectual disability have a higher risk of developing mental disorders compared to the general population. Available evidence suggests those with an intellectual disability receiving inpatient treatment in general psychiatric wards may have certain unique characteristics.
Method: Data gathered from a retrospective review of records of adults with intellectual disability admitted to general psychiatry wards in a tertiary psychiatric hospital in Singapore were analysed.

Aim: As a central component of schizophrenia psychopathology, negative symptoms result in detrimental effects on long-term functional prognosis. However, the neurobiological mechanism underlying negative symptoms remains poorly understood, which limits the development of novel treatment interventions. This study aimed to identify the specific neural fingerprints of negative symptoms in schizophrenia.

Physical Restraint (PR) is a coercive procedure used in emergency psychiatric care to ensure safety in life-threatening situations. Because of its traumatic nature, studies emphasize the importance of considering the patient's subjective experience. We pursued this aim by overcoming classic qualitative approaches and innovatively applying a multilayered semiautomated language analysis to a corpus of narratives about PR collected from 99 individuals across seven mental health services in Italy.

In West Africa, the long-term consequences of poor early psychosis recovery include poverty, neglect, and community ostracization. To understand the potential for digital health approaches to support early psychosis care in Ghana, we conducted a survey study among early psychosis patients and their caregivers about mental health needs, technology use and access, and interest in digital mental health. Hospital staff at Accra Psychiatric Hospital reviewed hospital medical records from January 2023 - December 2023 identifying young adults (≥18 years old) who had experienced psychosis symptoms for the first time within the prior five years.

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.
