Introduction: Alzheimer's disease and other dementia have a higher incidence among women and that risk factors specific to the female sex could be involved. Few studies looked into female reproductive factors and their association with dementia in low-and middle-income countries.
Materials And Methods: We analyzed the baseline data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil) and included data from 2594 women aged 60 years and older.
Background And Hypothesis: When occurring in adolescence, psychotic experiences (PE), subclinical psychotic symptoms, can be an early marker of mental illnesses. Studies with high-risk populations for psychosis show that anxiety symptoms often precede the onset of psychosis. Although anxiety symptoms are frequently experienced across the continuum of psychosis, no previous study has analyzed this association using a cross-lagged panel model (CLPM) longitudinally to identify if anxiety can be a predictor of PE over time or vice versa.

Yet few nationally representative studies from Latin American LMICs have investigated life-course socioeconomic factors associated with the susceptibility to these two cognitive conditions. Hence, the present study aimed to examine the associations of early- (education and food insecurity), mid- (employment stability), and late-life (personal income and household per capita income) socioeconomic determinants of CIND and dementia among older adults from Brazil, while simultaneously exploring whether sex plays an effect-modifier role on these associations.

We aimed to estimate the prevalence of SMCs in a large, nationally representative sample of older adults from Brazil and to identify sociodemographic and health-related factors that are associated with SMCs independently of objective memory.
Methods: Baseline data (n = 7831) from the ELSI-Brazil study, a national representative sample of adults aged 50 and over.
Background: Psychotic experiences are common in adults, adolescents, and children. While usually self-limited, they can indicate psychosis proneness when persistent. The Community Assessment of Psychic Experiences (CAPE) measures lifetime psychotic experiences in three dimensions.

Objectives: Hearing loss, depression, and cognitive decline are common among older people. We investigated the association of hearing loss with depressive symptoms and cognitive function in a nationally representative sample of people aged 50+ in Brazil.
Methods: Data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil) included information on self-reported hearing loss, hearing aid use (effective or not effective), depressive symptoms (CES-D-8), and a global cognitive score (composed of immediate and late recall, verbal fluency, orientation and prospective memory) in a sample of 9412 individuals.
Objectives: Ketamine has a fast onset of action that may offer a paradigm change for depression management at the end of life. We aimed to synthesize evidence regarding the safety and efficacy of ketamine in depression treatment within a broad palliative care concept.
Methods: We searched seven databases and included studies on the safety and efficacy of ketamine for depression treatment in patients diagnosed with any life-threatening disease.
Crime is a major public problem in low- and middle-income countries (LMICs) and its preventive measures could have great social impact. The extent to which multiple modifiable risk factors among children and families influence juvenile criminal conviction in an LMIC remains unexplored; however, it is necessary to identify prevention targets. This study examined the association between 22 modifiable individual and family exposures assessed in childhood (5-14 years, n = 2511) and criminal conviction at a 7-year follow-up (13-21 years, n = 1905, 76% retention rate) in a cohort of young people in Brazil.

Nevertheless, the probability of responding or not after each dose in the real-world remains unknown. This study aimed to estimate it throughout four doses of esketamine, administrated via subcutaneous (SC).

Thus, we examined the longitudinal invariance of the negative dimension using the positive and negative syndrome scale (PANSS) in an antipsychotic-naïve first-episode schizophrenia sample at baseline and after 10 weeks.
Methods: Our study was conducted at a specialized early intervention service.

Ketamine can quickly relieve depression, and its subcutaneous administration appears to be as effective as and probably safer than its standard intravenous administration. Herein, we report a case verifying the antidepressant effect of a subcutaneous esketamine formulation.
