Background And Purpose: The Family Questionnaire-Brazilian Portuguese Version (FQ-BPV) has been preliminarily validated in the Brazilian population. This study assessed the predictive validity of the FQ-BPV for relapse in patients with schizophrenia.
Methods: Ninety-four dyads (patients with schizophrenia and their relatives) were recruited from three mental health clinics. Expressed emotion was assessed using the FQ-BPV. Presence of relapse was assessed at 6-, 9-, 12-, and 18-month follow-ups and analyzed through logistic regressions.
Results: The critical comments (CC) domain of the FQ-BPV was statistically significant at 18 months. However, the model was not sufficiently robust to classify individuals correctly into relapse or no relapse categories.
Conclusion: The FQ-BPV did not predict relapse well and we cannot recommend it for that purpose in Brazil without further studies.

This research article presents a thorough and all-encompassing examination of predictive models utilized in the estimation of viscosity for ionic liquid solutions. The study focuses on crucial input parameters, namely the type of cation, the type of anion, the temperature (measured in Kelvin), and the concentration of the ionic liquid (expressed in mol%). This study assesses three influential machine learning algorithms that are based on the Decision Tree methodology.

Cuproptosis, a newly identified form of cell death, has drawn increasing attention for its association with various cancers, though its specific role in colorectal cancer (CRC) remains unclear. In this study, transcriptomic and clinical data from CRC patients available in the TCGA database were analyzed to investigate the impact of cuproptosis. Differentially expressed genes linked to cuproptosis were identified using Weighted Gene Co-Expression Network Analysis (WGCNA).
