A total of 30 articles were included, sourced from PubMed, Embase, Cochrane, and IBECS databases. Of these, 11 focused on protective factors and 19 on preventive interventions. Critical analysis of the articles revealed that the most researched protective factors are self-acceptance and an inclusive school environment, while the primary interventions focused on mitigating minority stress through various therapies. Additionally, other interventions with different objectives were identified. The transdiagnostic approach is being applied in multiple therapies and is of particular interest, as certain mental health stressors appear to be common across the entire LGTBIQ+.<!--> <!-->community. A key limitation is that several of the studies are ongoing, preventing the extraction of conclusive results. We conclude that some challenges remain, such as the limited exploration of self-harming behaviors among bisexual individuals and the lack of studies outside school settings. A positive school environment emerges as a significant protective factor, while preventive interventions, though promising, require further investigation and exploration of options such as family therapy and mindful self-compassion. In the future, it is crucial to improve interventions during critical moments of suicidal behavior and assess their effectiveness in conjunction with other strategies.</div></div>","PeriodicalId":39337,"journal":{"name":"Psiquiatria Biologica","volume":"32 3","pages":"Article 100730"},"PeriodicalIF":0.0,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144106778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extended-release aripiprazole is an antipsychotic used in the maintenance treatment of schizophrenia in stabilised adults. The extended-release injectable (ERI) formulation has been shown to increase adherence and reduce relapse rates compared to oral antipsychotics. In the case described, patients with a mean age of 45 years and diagnoses of paranoid schizophrenia, bipolar disorder and delusional disorder were psychopathologically stable for more than a year on monthly aripiprazole treatment (400 mg or 300 mg). Three months ago, treatment was changed to bimonthly administration of 960 mg.</div><div>Comparing the efficacy: in psychopathological stability, patients have remained stable, without relapse or symptomatology, during the three months following the switch to bimonthly administration. This suggests that the efficacy of the bimonthly formulation is comparable to the monthly formulation in terms of maintaining clinical stability. Regarding the treatment adherence, the bimonthly formulation (Abilify Maintena 960 mg every two months) allows for better adherence to treatment. This is because it reduces the frequency of administration, which may be beneficial for patients on outpatient follow-up. In drug levels, the bimonthly formulation avoids sharp peaks and troughs in drug levels, which may result in better symptom control and a reduction in the frequency of relapses. With regard to patient follow-up, although bimonthly administration reduces the frequency of visits to receive treatment, it still allows healthcare professionals to maintain regular contact with patients, improving follow-up and assessment of their progress. In patient preference, the TSQM (Treatment Satisfaction Questionnaire for Medication) questionnaire mentioned in the study will allow assessment of patient satisfaction with treatment, which is crucial for comparing perceived efficacy between monthly and bimonthly formulations.</div><div>It is important to note that although initial results appear promising, the three-month observation period is relatively short. Long-term follow-up is recommended to confirm the sustained efficacy of the bimonthly formulation compared to the monthly formulation. In conclusion, based on the sustained stability of patients and the potential advantages in terms of adherence and medication levels, the bimonthly extended-release formulation of aripiprazole appears to be as effective as the monthly formulation in the maintenance treatment of patients with severe mental disorder on outpatient follow-up. However, long-term studies with larger samples are needed to confirm these preliminary findings.</div></div>","PeriodicalId":39337,"journal":{"name":"Psiquiatria Biologica","volume":"32 3","pages":"Article 100725"},"PeriodicalIF":0.0,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143924438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This case report details a 23-year-old male with confirmed 22q11.2DS who presented with acute psychosis, following a history of developmental delays, attention deficit hyperactivity disorder, obsessive-compulsive disorder, and cognitive impairments. The neuropsychiatric symptoms are attributed to genetic disruptions in dopamine and glutamate pathways, notably involving the COMT and PRODH genes, which contribute to dopaminergic dysregulation and NMDA receptor dysfunction. Neuroimaging supports these findings, with structural anomalies in the prefrontal cortex and thalamus. The case exemplifies the complex interaction of genetic predisposition and environmental stressors in the onset of schizophrenia in 22q11.2DS. Early intervention targeting both genetic factors and environmental stressors is critical in managing the neuropsychiatric burden in this population, emphasizing the need for comprehensive, multidisciplinary care.</div></div>","PeriodicalId":39337,"journal":{"name":"Psiquiatria Biologica","volume":"32 2","pages":"Article 100714"},"PeriodicalIF":0.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143682110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
