Borderline personality disorder (BPD) is a severe psychiatric condition that affects up to 2.7% of the population and is highly linked to functional impairment and suicide. Despite its severity, there is a lack of knowledge about its pathophysiology. Studies show genetic influence and childhood violence as factors that may contribute to the development of BPD; however, the involvement of neuroinflammation in BPD remains poorly investigated. This article aimed to explore the pathophysiology of BPD according to the levels of brain-derived neurotrophic factor (BDNF), inflammatory cytokines, and oxidative stress substances that exacerbate neuronal damage. Few articles have been published on this theme. They show that patients with BPD have a lower level of BDNF and a higher level of tumor necrosis factor (TNF)-a and interleukin (IL)-6 in peripheral blood, associated with increased plasma levels of oxidative stress markers, such as malondialdehyde and 8-hydroxy-2-deoxyguanosine. Therefore, more research on the topic is needed, mainly with a pre-clinical and clinical focus.

The use of bladder antimuscarinics is very common in the elderly. However, recent population-based studies that assessed the use of anticholinergics or bladder antimuscarinics showed an increased risk of dementia when these drugs were used for a prolonged period. Several of these population-based studies included patients who used solifenacin, which is a bladder antimuscarinic released in 2005 with the prospect of being a more selective antimuscarinic for M3 receptors (M3R), which could make it a safer drug when trying to avoid unwanted effects of older bladder antimuscarinics such as oxybutynin, especially with regard to changes in cognition. Since the various bladder antimuscarinics have distinct pharmacological characteristics, such as in the ability to penetrate the blood-brain barrier, in selectivity for muscarinic receptors, and in brain efflux mechanisms, their effects on the central nervous system (CNS) may vary. Solifenacin was the drug selected in this review, which aims to describe the results of several articles published in recent years reporting the effects of solifenacin on cognition or the risk of dementia development. Although preclinical studies show that solifenacin can also act on brain M1 receptors (M1R), short-term clinical studies have shown it to be safe for cognition. However, there are no long-term randomized studies that prove the safety of this drug for the CNS. Thus, until the safety of solifenacin has been established by long-term studies, it seems advisable to avoid prolonged use of this drug in elderly patients.

Objetivos: Analisar as principais produções da literatura científica brasileira sobre a prevalência e os fatores associados aos transtornos mentais entre estudantes universitários da área da saúde. Fonte de dados: Foi realizada uma revisão narrativa da literatura nas bases de dados Scielo, PubMed e Science Direct, sendo incluídas 15 pesquisas originais sobre o tema.  Conclusão: O cuidado em saúde mental durante a graduação, com ênfase na prevenção do adoecimento mental dos estudantes da saúde, perpassa por nuances que exigem dos alunos diversas adaptações. É urgente e necessário o envolvimento das instituições de ensino no desenvolvimento de políticas educacionais e oferta de serviços de suporte terapêutico nesse processo.Palavras-chave: Saúde Mental.
