We aimed to test the performance of IDEA-RS in an independent, community-based, school-attending sample within the same country: the Brazilian High-Risk Cohort. Methods: Standard external validation, refitted, and case mix-corrected models were used to predict depression among 1442 youth followed from a mean age of 13.5 years at baseline to 17.7 years at follow-up, using probabilities calculated with IDEA-RS coefficients. Results: The area under the curve was 0.65 for standard external validation, 0.70 for the case mix-corrected model, and 0.69 for the refitted model, with discrimination consistently above chance for predicting depression in the new dataset. There was some degree of miscalibration, corrected by model refitting (calibration-in-the-large reduced from 0.77 to 0). Conclusion: IDEA-RS was able to parse individuals with higher or lower probability of developing depression beyond chance in an independent Brazilian sample. Further steps should include model improvements and additional studies in populations with high levels of subclinical symptoms to improve clinical decision making.","PeriodicalId":9246,"journal":{"name":"Brazilian Journal of Psychiatry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84119818","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}

Some months after the remission of acute COVID-19 infection, some people show depressive symptoms, which are predicted by increased peak body temperature (PBT) and lowered blood oxygen saturation (SpO2). Nevertheless, no data indicate whether Long COVID is associated with increased insulin resistance (IR) in association with depressive symptoms and immune, oxidative, and nitrosative (IO&NS) processes. Methods. We used the homeostasis Model Assessment 2 (HOMA2) calculator to compute beta-cell function, insulin sensitivity and resistance (HOMA2-IR) and measured the Beck Depression Inventory (BDI) and the Hamilton Depression Rating Scale (HAMD) in 86 Long COVID patients and 39 controls. We examined the associations between the HOMA2 indices and PBT and SpO2 during acute infection, and depression, IO&NS biomarkers (C-reactive protein, NLRP3 activation, myeloperoxidase, and advanced oxidation protein products) 3-4 months after the acute infection. Results. Long COVID is accompanied by increased HOMA2-IR, fasting blood glucose, and insulin levels. We found that 33.7% of the patients versus 0% of the controls had HOMA2-IR values >1.8, suggesting IR. PBT, but not SpO2, during acute infection significantly predicted IR, albeit with a small effect size. Increased IR was significantly associated with depressive symptoms as assessed with the BDI and HAMD above and beyond the effects of IO&NS pathways. There were no significant associations between increased IR and the activated IO&NS pathways during Long COVID. Conclusion. Long COVID is associated with new-onset IR in a subset of patients. Increased IR may contribute to the onset of depressive symptoms due to Long COVID by enhancing overall neurotoxicity.","PeriodicalId":9246,"journal":{"name":"Brazilian Journal of Psychiatry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78637012","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}

Despite the generalization of mental health care in our environment, the incidence of depression continues to grow and it is now one of the leading causes of disability. Globally, its estimated cost is one trillion dollars per year, mainly due to decreased productivity from work absenteeism. Most mental health care is carried out in clinical settings, which limits early detection and the possibility of acting on the incidence of mental conditions. Thus, early intervention strategies are needed in the fields of prevention (primary and secondary) and mental health promotion. The work environment is considered the ideal place for these activities since the general population spends a large part of their time there. According to the World Health Organization, intensifying mental health care in the general population will result in a high economic return: for every dollar invested in depression and anxiety four dollars are saved, mainly through increased productivity at work. Intervention costs could be shared with the private sector, since companies will be interested in the economic return. Workplace interventions can impact work performance, which is a central domain of mental health promotion and is affected by workload, lack of participation and control, monotonous and unpleasant tasks, poor interpersonal relationships, precarious working conditions, and lack of leadership and communication. A number of interventions have been found to effectively reduce depressive symptoms and prevent their onset. They involve different formats (individual, group, self-administered, face-to-face, or telematic) and content (psychoeducation, exercise promotion, and psychological therapies). However, further research is needed to determine which have the best results. Professional care in the workplace also allows early detection of mental disorders and referral for treatment. In the context of the COVID-19 pandemic and due to its impact on the mental health of the working population, telehealth interventions may allow safer and more inexpensive interventions. A recent meta-analysis found that the mental health of health care workers has been especially affected, and thus this group is of particular interest. One in four health professionals have suffered significant depressive symptoms during the pandemic, and more than one in three are suffering from burnout. Other symptoms include insomnia, anxiety and post-traumatic features. They are being prioritized in public health policies. In conclusion, interventions to prevent mental disorders and promote mental health in the workplace are costeffective and could decrease the incidence of depression and reduce work absenteeism. During the COVID-19 pandemic, telehealth interventions for health professionals are highly important.","PeriodicalId":9246,"journal":{"name":"Brazilian Journal of Psychiatry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82469500","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}

Methods: Thirty-three patients of both sexes with PTSD were recruited and randomized 1:1 into two groups. One group received oral CBD (300 mg), and the other received a placebo before listening to a digital audio playback of their previously recorded report of the trigger event. Subjective and physiological measurements were taken before and after recall. We analyzed the data in two subsamples: trigger events involving sexual and nonsexual trauma. Results: In the nonsexual trauma group, the differences between measurements before and after recall were significantly smaller with CBD than placebo; this held true for anxiety and cognitive impairment. However, in the sexual trauma group, the differences were non-significant for both measurements.
