RESUMO

This systematic review addresses the complex nature of Panic Disorder (PD), characterized by recurrent episodes of acute fear, with a focus on updating and consolidating knowledge regarding neurochemical, genetic, and epigenetic factors associated with PD. Utilizing the PRISMA methodology, 33 original peer-reviewed studies were identified, comprising 6 studies related to human neurochemicals, 10 related to human genetic or epigenetic alterations, and 17 animal studies. The review reveals patterns of altered expression in various biological systems, including neurotransmission, the Hypothalamic-Pituitary-Adrenal (HPA) axis, neuroplasticity, and genetic and epigenetic factors leading to neuroanatomical modifications. Noteworthy findings include lower receptor binding of GABAA and serotonin neurotransmitters in the amygdala. The involvement of orexin (ORX) neurons in the dorsomedial/perifornical region in triggering panic reactions is highlighted, with systemic ORX-1 receptor antagonists blocking panic responses. Elevated Interleukin 6 and leptin levels in PD patients suggest potential connections between stress-induced inflammatory changes and PD. Brain-derived neurotrophic factor (BDNF) and tyrosine receptor kinase B (TrkB) signaling are implicated in panic-like responses, particularly in the dorsal periaqueductal gray (dPAG), where BDNF's panicolytic-like effects operate through GABAA-dependent mechanisms. GABAergic neurons' inhibitory influence on dorsomedial and posterior hypothalamus nuclei is identified, potentially reducing the excitability of neurons involved in panic-like responses. The dorsomedial hypothalamus (DMH) is highlighted as a specific hypothalamic nucleus relevant to the genesis and maintenance of panic disorder. Altered brain lactate and glutamate concentrations, along with identified genetic polymorphisms linked to PD, further contribute to the intricate neurochemical landscape associated with the disorder. The review underscores the potential impact of neurochemical, genetic, and epigenetic factors on the development and expression of PD. The comprehensive insights provided by this systematic review contribute to advancing our understanding of the multifaceted nature of Panic Disorder and pave the way for targeted therapeutic strategies.

RESUMO

Introduction: The following work aims to compare the types and magnitude of risk events in patients with Schizophrenia and Bipolar Disorder and each of those groups with of a group of healthy siblings, exploring differences and similarities of the two psychotic disorders. Methods: Retrospective interviews were conducted with 20 families to investigate maternal and obstetric health, social support and the presence of early trauma for the affected family members and healthy siblings. Mothers were interviewed with the Prenatal Psychosocial Profile and each family participant was assessed with the Early Trauma Inventory, Screening Questionnaire of the Genomic Psychiatry Cohort and the Diagnostic Interview for Psychosis and Affective Disorders. Results: Obstetric and gestational history, pregnancy weight changes and early trauma were associated with offspring's mental illness, including statistically significant findings for complications of pregnancy, pregnancy weight changes, general trauma, physical punishment and emotional abuse. Conclusion: These findings highlight the different risk factor exposures that occur within a family, which may increase the risk for severe mental illness.

RESUMO

Introduction: Major Depressive Disorder (MDD) is a chronic, recurrent, and highly prevalent disease that is associated with significant functional disability. During pregnancy, the prevalence of the disease is approximately 20%, with 12% of these, requiring treatment to avoid important negative consequences for the mother-baby binomial. Risk-benefit assessment of the use of antidepressants during pregnancy is mandatory, in addition to knowledge of the long-term effects of prenatal exposure to these drugs in the offspring. In this study, we will perform an updated systematic review and meta-analysis to explore the treatment of depression during pregnancy, along with its effectiveness, safety, and possible harm to women and children. Materials and methods: We will search for publications in the following databases: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Web of Science, Scopus, Lilacs, and PsycINFO. The reference lists of the included studies will be manually reviewed to identify potentially relevant studies. There will be no restrictions on language or date of publication. Quality assessment of the included studies will be performed independently according to the Cochrane Risk of Bias (RoB2) instrument. To assess the certainty of the findings' body of evidence, we will use the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. This study aimed to ascertain the efficacy and safety of antidepressants in pregnant women and children. Ethics and dissemination: Ethical approval was not required as individual patient data were not collected. Dissemination: Plan to publish a systematic review in an open-access medical journal at the end of the process. Systematic Review Registration: PROSPERO, CRD42023447694.

RESUMO

OBJECTIVE: To adapt the Scale of Perception of Respect for and Maintenance of the Dignity of the Inpatient (CuPDPH) to the Brazilian language and culture and to assess its psychometric properties. RESULTS: The scale was evaluated by 15 experts, and 239 patients from three tertiary hospitals in Rio de Janeiro. All participants signed a consent form. Data have shown adequacy of the model (KMO=0.839, Bartlett's test of sphericity: χ2(171) = 2241.3, p = 0.000010), good adjusted content validity (CVCa ≥ 0.90), internal consistency and reliability, such as α = 0.927. DISCUSSION: CuPDPH is a rating scale on observable professional attitudes. Illnesses change lives and impose adaptation to a new situation, perceived as depersonalization, leading patients to try to regain control of their lives. Patients expressed "ill will" to fill out the scale. Psychiatric patients' scale filling time was higher than others. A sample from three Rio de Janeiro third-level hospitals may not reflect the country's population; also, this adaptation may not comprise all linguistic variations of Brazilian Portuguese and Portuguese-speaking countries. CONCLUSION: The Portuguese version of the Scale of Perception of Respect for and Maintenance of the Dignity of the Inpatient (CuPDPH), a 19-item, six-component version is a reliable instrument to measure the perception of internal medicine, surgical, and psychiatric patients on the maintenance of their dignity in Rio de Janeiro, Brazil. This knowledge could be used in advancing research on patients' perception of dignity, as well as professional ethical competencies, staff-patient relationship skills, and leadership development in medical and other healthcare professional education.

RESUMO

OBJECTIVE: To perform a meta-analysis and comparison between high-income, and low- and middle-income countries postpartum depression symptoms prevalences. METHODS: PubMed, Embase, Virtual Health Library, Scopus, Web of Science, PsycINFO and CINAHL databases were searched until October 2022 for studies that collected data from pandemic. The metaprop command was used in the Stata statistical software v.12.0 to run a random-effects meta-analysis. RESULTS: A total of 15 studies with 4,788 postpartum women were included. The overall prevalence of postpartum depression symptoms was 31% (95% CI: 21.85-40.99). The pooled prevalence of postpartum depression symptoms among women from high-income countries [30.5% (95% CI: 16.95-46.02)] did not differ significantly from that among women from low- and middle-income countries [31.5% (95% CI: 19.26-45.15)]. However, studies that analyzed women up to one month after childbirth had a lower prevalence of postpartum depression symptoms [17.5% (95% CI: 9.85-26.62)] compared to those that observed them up to one year after childbirth [38.3% (95% CI: 33.96-42.83)]. CONCLUSIONS: The prevalence of postpartum depression symptoms was high regardless of the country's human development index and it must be regularly tracked around the world to assess, discuss, and recommend more assertive steps that may be implemented based on the particular characteristics of each country.

RESUMO

Objective: To adapt the Mind-Wandering Questionnaire (MWQ) for the Brazilian context and present evidence of validity based on its internal structure. Methods: A total of 2,682 Brazilian adults from different regions of the country took part in this study. Confirmatory factor analyses and multigroup confirmatory factor analyses (MGCFA) were performed to assess the factor structure of the MWQ. McDonald's omega (ω) was generated to provide reliability indexes. Results: The analyses demonstrated an adequate factor structure for the MWQ adapted to the Brazilian context, corroborating the original article's single-factor model and other adaptation studies. Furthermore, the results demonstrated the instrument's reliability in a Brazilian population (ω = 0.88). Conclusion: The MWQ is thus an adequate, reliable, and quickly administered instrument for those whose aim is to measure deliberate and spontaneous MW in Brazil.
