Article Synopsis
  • A study analyzed the effects of immune checkpoint inhibitors (ICIs) on patients with advanced non-small cell lung cancer (NSCLC) and found that ICIs can significantly improve survival rates and reduce the risk of disease progression.
  • The research involved a large population of patients who received palliative chemotherapy from 2013 to 2020, revealing that ICI-treated patients had a lower adjusted hazard ratio for death compared to those not receiving ICIs.
  • Despite the improved clinical outcomes with ICIs, the study noted an increase in medical expenses per patient, highlighting the need for further research to determine which patients would benefit most from ICI treatments.

Background: As clinical practices with lithium salts for patients diagnosed with bipolar disorder (BD) are poorly documented in Asia, we studied the prevalence and clinical correlates of lithium use there to support international comparisons.

Methods: We conducted a cross-sectional study of use and dosing of lithium salts for BD patients across 13 Asian sites and evaluated bivariate relationships of lithium treatment with clinical correlates followed by multivariate logistic regression modeling.

Results: In a total of 2139 BD participants (52.

Article Synopsis
  • In 2011, the Korean Neuropsychiatric Association renamed schizophrenia from 'mind split disorder' to 'attunement disorder' to help reduce stigma, but the impact of this change on social perceptions remains unclear.
  • A study analyzed media representations of schizophrenia before and after the renaming to see if media coverage influences the public's perception, revealing that negative descriptions persisted throughout.
  • The findings indicate that despite the renaming effort, social perceptions of schizophrenia remain negatively biased, suggesting a need for more balanced media coverage to effectively reduce stigma.

Article Synopsis
  • This study analyzes the prescription patterns of mood stabilizers, primarily used for bipolar disorder, across 10 Asian countries and highlights their use in treating other psychiatric conditions.
  • It found that more than half of the patients had schizophrenia or similar disorders, and symptoms like irritability and aggression were common targets for treatment.
  • The results suggest that while mood stabilizers are frequently used off-label for various psychiatric diagnoses, the effectiveness and justification of this practice need further research.

Background: Pharmacoepidemiological studies of clozapine use to treat bipolar disorder (BD), especially in Asia, are rare, although they can provide insights into associated clinical characteristics and support international comparisons of indications and drug dosing.

Methods: We examined the prevalence and clinical correlates of clozapine treatment for BD in 13 Asian countries and regions (China, Hong Kong SAR, India, Indonesia, Japan, Korea, Malaysia, Myanmar, Pakistan, Singapore, Sri Lanka, Taiwan, and Thailand) within an Asian Prescription Patterns Research Consortium. We compared BD patients treated with clozapine or not in initial bivariate comparisons followed by multivariable logistic regression modeling.

Major depression is impacted by the disruption of gut microbiota. Defects in gut microbiota can lead to microbiota-gut-brain axis dysfunction and increased vulnerability to major depression. While traditional chemotherapeutic approaches, such as antidepressant use, produce an overall partial therapeutic effect on depression, the gut microbiome has emerged as an effective target for better therapeutic outcomes.

Background: Acute appendicitis often presents with vague abdominal pain, which fosters diagnostic challenges to clinicians regarding early detection and proper intervention. This is even more problematic with individuals with severe psychiatric disorders who have reduced sensitivity to pain due to long-term or excessive medication use or disturbed bodily sensation perceptions. This study aimed to determine whether psychiatric disorder, psychotropic prescription, and treatment compliance increase the risks of complicated acute appendicitis.

Psychotic symptoms are rarely concurrent with the clinical manifestations of depression. Additionally, whether psychotic major depression is a subtype of major depression or a clinical syndrome distinct from non-psychotic major depression remains controversial. Using data from the Research on Asian Psychotropic Prescription Patterns for Antidepressants, we developed a machine-learning-algorithm-based prediction model for concurrent psychotic symptoms in patients with depressive disorders.
