Effect of Apelin-13 on behavioral changes and hippocampal autophagy of mice with posttraumatic stress disorder / 中华行为医学与脑科学杂志

Objective:To investigate the effect and the neural mechanisms of Apelin-13 on the behavior changes of posttraumatic stress disorder (PTSD) model mice.Methods:Totally 32 SPF grade male C57BL/6J mice aged 6 weeks were divided into 4 groups randomly ( n=8 in each group): control group, model group, normal saline group and Apelin-13 group.The mice model of PTSD was established by single-prolonged stress (SPS) method. The mice in normal saline group and Apelin-13 group were respectively given lateral ventricular microinjection of 0.9% sodium chloride solution (2 μL) and Apelin-13 (1.5 μg/μL, 2 μL)after PTSD modeling. The behaviors of mice were evaluated by open field test, elevated plus maze test and Morris water maze test.The morphological structure and numerical changes of hippocampal neurons were observed by hematoxylin and eosin (HE) staining.The expression of phosphoinositide 3-kinase(PI3K), phosphorylated-PI3K(p-PI3K), protein kinase B(Akt), phosphorylated-Akt (p-Akt), forkhead box O3a (FoxO3a), phosphorylated-FoxO3a(p-FoxO3a), autophagy-related proteins including microtubule-associated protein 1 light chain 3(LC3) and sequestosome 1(p62) were detected by Western blot. SPSS 26.0 software was used for data analysis.The escape latency data of repeated learning training in Morris water maze was conducted by repetitive measurement ANOVA.The comparison of other data among multiple groups was conducted by one-way ANOVA and further pairwise comparisons were conducted by LSD test and Tamhane test. Result:(1) Open field test results showed statistically significant differences in the central area activity distance and residence time in central area among mice in the four groups ( F=15.37, 9.63, both P<0.05). The central area activity distance ((0.06±0.03) m) and residence time ((2.48±1.02) s) of the mice in model group were lower than those of the control group ((0.19±0.05) m, (15.00±8.91) s)(both P<0.05). And the central area activity distance((0.12±0.04)m)and the residence time((13.56±7.64)s)were higher than those of model group((0.06±0.03)m, (2.48±1.02)s)and normal saline group((0.06±0.02)m, (2.82±1.52)s)(all P<0.05). Elevated plus maze test results showed statistically significant differences in the numbers and time entering open arms among the four groups ( F=10.74, 19.12, both P<0.05). The numbers((4.50±2.51) times) and the time ((26.95±17.48) s) entering the open arm of mice in model group were both lower than those of the control group ((13.75±4.71) times, (103.75±42.43)s) and Apelin-13 group ((10.00±5.18) times, (55.98±19.49) s) (all P<0.05). Morris water maze test results showed that in the 4-day learning and training phase, the time and group interaction of escape latency was not significant among the four groups ( F=1.15, P=0.34), but time main effect and group main effect were significant ( F=131.65, 16.98, both P<0.05). On the 2nd to 4th day, mice in model group showed significantly increased escape latency than mice in control group and Apelin-13 group(both P<0.05). And the numbers crossing original platform and the time in the target quadrant of Apelin-13 group were both higher than those of model group and normal saline group (all P<0.05). (2) HE staining results showed that neurons in the hippocampal CA1 and CA3 area of mice in model group and normal saline group were swollen and arranged loosely.The hippocampal neurons in control group and Apelin-13 group were arranged neatly and densely. (3) Western blot results showed statistically significant differences in the protein expression of p-PI3K, p-Akt, p-FoxO3a, p62 and the ratio of LC3Ⅱ/LC3Ⅰ among the four groups ( F=21.37, 37.35, 20.71, 13.26, 37.65, all P<0.05). The protein expression of p-PI3K, p-Akt, p-FoxO3a and p62 in Apelin-13 group((0.92±0.07), (0.90±0.09), (0.89±0.13), (1.03±0.08)) were higher than those in model group((0.59±0.04), (0.50±0.07), (0.49±0.11), (0.68±0.04)) and normal saline group((0.61±0.06), (0.50±0.08), (0.53±0.11), (0.70±0.05))(all P<0.05), and the ratio of LC3Ⅱ/LC3Ⅰ in Apelin-13 group(0.60±0.06) was lower than those in model group(0.92±0.10) and normal saline group(0.99±0.05) (both P<0.05). Conclusion:Apelin-13 can alleviate the anxiety-like behavior and impaired spatial learning and memory in PTSD model mice. The mechanism may be related to the up-regulation of PI3K/Akt/FoxO3a autophagy pathway.

The best of two worlds: Combining the DSM-5 and ICD-11 clusters of symptoms for posttraumatic stress disorder in a single screening scale

Objectives: The most recent DSM-5 (2013) and ICD-11 (2018) diagnostic criteria for posttraumatic stress disorder (PTSD) encompass 20 and six symptoms, respectively, organized in different structures. This study aimed to investigate the dimensions of the Posttraumatic Stress Disorder Checklist 5 (PCL-5) according to the DSM-5's broader definition of PTSD and the ICD-11's narrower approach, as well as to explore an alternative restricted model that retains the core symptoms explicitly related to traumatic experiences. Methods: Data were gathered from Brazilian employees (n=1,101) who had directly experienced traumatic life events or had been exposed to them because of their work activities. Confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) were used to evaluate the configural and metric structures of the models. Results: We estimated seven models of the latent structure of PTSD including the four-factor DSM-5 and three-factor ICD-11 PTSD models. Given the lack of evidence of their validity, an alternative 10-symptom model was tested. The final seven-item PTSD model considerably improved estimation of the PTSD construct. This solution showed reliable items with non-redundant content, acceptable fit indices, and satisfactory configural and metric properties. Conclusion: The more parsimonious one-dimensional model comprising the core PTSD symptoms has the potential to improve assessment of PTSD.

Constituição psíquica e linguística de um sujeito com transtorno do espectro do autismo imerso em uma família vulnerável pela imigração no pós-guerra / Psychic and linguistic constitution of a subject with autism spectrum disorder immersed in a family vulnerable by post-war immigration / Constitución psíquica y lingüística de un sujeto con trastorno del espectro autismo inmerso en una familia vulnerable por inmigración de posguerra

Introdução: este artigo apresenta a constituição psíquica e linguística de um jovem autista, proveniente de uma família de imigrantes em situação de pós-guerra, em que entram em questão temas como o luto, a constituição psíquica transgeracional, e a presença de angústias no processo de desenvolvimento da criança em uma situação singular que é a presença do autismo. Objetivo: analisar os efeitos singulares da imigração e multiculturalismo em um caso de autismo e sua evolução terapêutica. Método: estudo de caso longitudinal, que utilizou diário clínico e filmagens de sessões com observações do desenvolvimento de Rafael, desde os dezoito meses até a idade adulta. Como abordagem terapêutica e análise dos resultados, foram utilizados aportes da constituição psíquica da teoria psicanalítica, e sobre o desenvolvimento linguístico em uma perspectiva enunciativa. Resultados: O multiculturalismo acarretava um desafio maior ao processo de aquisição da linguagem por parte da criança com autismo, enquanto o silêncio consequente da dor do luto, presente nos adultos, dificultava a troca verbal e atrasava sua constituição psíquica. O autismo, por sua vez, apresentou-se como transtornos qualitativos na comunicação, necessitando maior investimento por parte de seus cuidadores para que a aquisição da linguagem se desse, pois o paciente precisou ser fisgado para a nossa cultura. Conclusão: Diante de todo esse quadro, o caso clínico demonstra a importância do suporte terapêutico à família e do investimento contínuo na subjetivação, considerando e valorizando os diferentes códigos culturais que compõem o núcleo familiar.

Introduction: this article presents the psychic and linguistic constitution of an autistic young man, from a post-war immigrant family, in which themes such as mourning, the transgenerational psychic constitution, and the presence of anxieties in the process come into question of the child development in a unique situation that is the presence of autism. Objective: to analyze the unique effects of immigration and multiculturalism in a case of autism and its therapeutic evolution. Method: longitudinal case study, which used a clinical diary and footage of sessions with observations of the development of R. from eighteen months to adulthood. As a therapeutic approach and analysis of results, contributions from the psychic constitution of psychoanalytic theory, and on linguistic development in an enunciative perspective, were used. Results: Multiculturalism posed a greater challenge to the process of language acquisition by the child with autism, while the consequent silence of the pain of grief, present in adults, hindered verbal exchange and delayed their psychic constitution. Autism, in turn, presented itself as qualitative disorders in communication, requiring greater investment on the part of its caregivers for the acquisition of language to take place, as it needed to be hooked for our culture. Conclusion: Given this situation, this clinical case demonstrates the importance of therapeutic support to the family and the continuous investment in subjectivity, considering and valuing the different cultural codes that make up the family nucleus.

Effect of Ganmai Dazao Decoction on ethology of rats with PTSD and its mechanism / 中国中药杂志

This study aimed to explore the effect of Ganmai Dazao Decoction on the ethology of rats with posttraumatic stress disorder(PTSD) and study the related mechanism through the changes in magnetic resonance imaging and protein expression. Sixty rats were randomly divided into 6 groups, namely the normal group, the model group, the low(1 g·kg~(-1)), medium(2 g·kg~(-1)), and high-dose Ganmai Dazao Decoction groups(4 g·kg~(-1)), and the positive control group(intragastric administration with 10.8 mg·kg~(-1) of fluoxetine), with 10 rats in each group. Two weeks after inducing PTSD by single-prolonged stress(SPS) in rats, the positive control group was given fluoxetine hydrochloride capsule by gavage, the low, medium, and high-dose groups were given Ganmai Dazao Decoction by gavage, and both the normal group and the model group were given the same volume of normal saline by gavage, each for 7 days. The open field experiment, elevated cross elevated maze, forced swimming experiment, and new object recognition test were carried out for the behavioral test. Three rats in each group were selected to detect the expression of neuropeptide receptor Y1(NPY1R) protein in the hippocampus by Western blot. Then, the other three rats in each group were selected to use the 9.4T magnetic resonance imaging experiment to observe the overall structural changes in the brain region and the anisotropy fraction of the hippocampus. The results of the open field experiment showed that the total distance and central distance of rats in the model group were significantly lower than those in the normal group, and the total distance and central distance of rats in the middle and high-dose Ganmai Dazao Decoction groups were higher than those in the model group. The results of the elevated cross maze test showed that medium and high-dose Ganmai Dazao Decoction remarkably increased the number of open arm entries and the residence time of open arm of rats with PTSD. The results of the forced swimming experiment showed that the immobility time in the water of the model group rats was significantly higher than that of the normal group, and Ganmai Dazao Decoction hugely reduced the immobility time in the water of rats with PTSD. The results of the new object recognition test showed that Ganmai Dazao Decoction significantly increased the exploration time of new objects and familiar objects in rats with PTSD. The results of Western blot showed that Ganmai Dazao Decoction significantly reduced the expression of NYP1R protein in the hippocampus of rats with PTSD. The 9.4T magnetic resonance examination found that there was no significant difference in the structural image among the groups. In the functional image, the fractional anisotropy(FA value) of the hippocampus in the model group was significantly lower than that in the normal group. The FA value of the hippocampus in the middle and high-dose Ganmai Dazao Decoction groups was higher than that in the model group. Ganmai Dazao Decoction reduces the injury of hippocampal neurons by inhibiting the expression of NYP1R in the hippocampus of rats with PTSD, thereby improving the nerve function injury of rats with PTSD and playing a neuroprotective role.

The effects of melatonin therapy on hypothalamic-pituitary-adrenal axis in rats with posttraumatic stress disorder / 神经解剖学杂志

Objective:To investigate the effects of melatonin(MLT)on hypothalamic-pituitary-adrenal(HPA)axis in posttraumatic stress disorder(PTSD)rats induced by foot shocks.Methods:The rat model of PTSD was prepared by plantar electroshock,and MLT was given by intraperitoneal injection.The behavioral changes of rats were detected by rejection reaction test,the mRNA expression of corticotropin-releasing hormone(CRH)in hypothalamus was detected by real time RT-PCR,and the contents of adrenocorticotropin hormone(ACTH),epinephrine(EPI)and glucocorticoid(GC)in serum were detected by enzyme-linked immunosorbent assay(ELISA).Results:In the PTSD group,the rejection reaction was obvious,the expression of CRH mRNA in hypothalamus was increased(P＜0.05),the serum ACTH and EPI were increased(P＜0.05),but the GC level was decreased(P＜0.05).After MLT treatment,the rejection reaction of PTSD rats was significantly alleviated,CRH mRNA expression in hypothalamus was decreased(P＜0.05),serum ACTH and EPI levels were decreased(P＜0.05),and GC levels were increased(P＜0.05).Conclusion:MLT treatment can relieve the symptoms of PTSD and restore the neuroendocrine balance of HPA axis in rats.

Psychological trauma and depression in recovered COVID-19 patients: a telecommunication based observational study

Abstract Introduction Coronavirus disease 2019 (COVID-19) is adversely affecting the mental health of patients infected with the virus and the psychological impact on recovered COVID-19 patients is unclear. Objectives The study aimed to assess posttraumatic stress disorder (PTSD) and depression among COVID-19 patients after recovery from the disease. Methods This cross-sectional study was conducted from November 9, 2020, to December 23, 2020. The study used a telemedicine model to enroll recovered COVID-19 patients from a database of patients provided by the health authorities. The National Stressful Events Survey PTSD Short Scale (NSESSS) for adults was used to assess PTSD symptoms and the Patient Health Questionnaire (PHQ-9) was used to assess depression. Results The study enrolled 503 recovered COVID-19 patients with a mean age of 41.90 years. The majority were asymptomatic (64.6%), while 21.5% had had moderate to severe forms of the disease. Prevalence rates of PTSD symptoms and depression were 56.9 and 29% respectively. COVID-19 patients with severe forms of the disease were significantly more affected by PTSD symptoms (vs. mild, odds ratio [OR] = 18.7, 95%confidence interval [CI] 9.9-35.5) and depression (vs. mild, OR = 19.8, 95% CI 9.9-39.5). Similarly, patients who required oxygen or ventilator support reported significantly higher rates of PTSD symptoms (vs. managed at home, OR = 17.4, 95% CI 8.3-36.4) and depression (vs. managed at home, OR = 22.0, 95% CI 10.1-47.7). Conclusion This study reports that recovered COVID-19 patients suffered from a significant amount of depression and experienced significant PTSD symptoms. It will help with addressing a major psychological concern among the recovered subjects.

Adaptación y validación del Cuestionario de Trastorno de Estrés Postraumático (COVID-19-PTSD) en población peruana / Adaptation and Validation of the Questionnaire on Posttraumatic Stress Disorder in a Peruvian Population

Introducción: La alta prevalencia de trastornos mentales como el estrés, en situaciones estresantes prolongadas inducidas por una pandemia, demanda su detección y valoración oportuna; para ello se requieren instrumentos contextualizados y con adecuadas propiedades métricas. Objetivo: Validar el Cuestionario sobre el Trastorno de Estrés Postraumático y Prevalencia de Sintomatología de Estrés Postraumático en población peruana. Métodos: Estudio de tipo instrumental, realizado en la región Ica del Perú, de junio a noviembre del 2021, en 412 participantes adultos. El proceso incluyó traducción al español, evaluación del contenido por jueces y prueba piloto. La validez de constructo se evaluó mediante el Análisis Factorial Exploratorio y el ajuste con Análisis Factorial Confirmatorio, que incluyó el Método de Estimación de Mínimos Cuadrados no Ponderados Robustos; se evaluó la confiabilidad con el Omega de McDonald y comparó la sintomatología del trastorno de estrés postraumático con variables generales. Resultados: Se obtuvo una versión de dieciocho ítems, agrupados en cuatro factores que explicaron el 70,78 por ciento de la varianza total y un ajuste aceptable [x2/gl = 1,54; NFI y CFI = 0,99; SRMR = 0,052; RMSEA = 0,036 (IC90 por ciento: 0,26-0,46)]. Los ítems discriminan de forma satisfactoria; así como la escala según variable sexo, estado civil y los que tienen familiar fallecido por COVID-19. La consistencia interna fue adecuada para la escala global (ω = 0,924) y sus dimensiones (EDA = 0,740; IEAN = 0,882; A = 0,786 y CE = 0,811). Conclusión: La nueva versión peruana del instrumento posee propiedades métricas aceptables; por tanto, se recomienda su uso para valorar el trastorno de estrés postraumático y estudios de validación(AU)

Introduction: The high prevalence of mental disorders such as stress, in prolonged stressful situations induced by a pandemic, demands their timely identification and assessment; in order to do this, contextualized instruments with adequate metric properties are required. Objective: To validate the Questionnaire on Posttraumatic Stress Disorder and Prevalence of Posttraumatic Stress Symptomatology in a Peruvian population. Methods: An instrumental study was conducted in the region of Ica, in Peru, from June to November 2021, with 412 adult participants. The process included translation into Spanish, content assessment by judges, and pilot testing. Construct validity was evaluated by exploratory factor analysis; and fit, with confirmatory factor analysis, which included the robust unweighted least squares estimation method. Reliability was evaluated with McDonald's Omega, while the posttraumatic stress disorder symptomatology was compared with general variables. Results: The obtained version included 18 items, grouped into four factors that explained 70.78 percent of the total variance. Also, an acceptable fit was obtained [x2/gl=1.54; NFI and CFI=0.99; SRMR=0.052; RMSEA=0.036 (90 percent CI: 0.26-0.46)]. The items discriminate satisfactorily, as does the scale according to sex, marital status and those with a family member who died from COVID-19. Internal consistency was adequate for the global scale (ω = 0.924) and its dimensions (EDA=0.740; IEAN = 0.882; A=0.786 and CE=0.811). Conclusion: The new Peruvian version of the instrument has acceptable metric properties; therefore, its use is recommended for assessing posttraumatic stress disorder and validation studies(AU)

Muito além do trauma: uma investigação sobre o papel das reações peritraumáticas sobre o transtorno de estresse pós-traumático / Beyond the trauma: an investigation of the role of peritraumatic reactions on posttraumatic stress disorder

O Transtorno de Estresse Pós-Traumático (TEPT) é uma condição debilitante que impacta significativamente a qualidade de vida dos seus portadores. Dentre vários fatores de risco para o TEPT, as reações peritraumáticas (RP), como a imobilidade tônica peritraumática (ITP), dissociação (DP) e reações físicas de pânico (RFP), estão entre as mais investigadas. No entanto, a maioria dos estudos avaliou essas RP separadamente, e o elo entre elas e o TEPT ainda não foi bem compreendido. Portanto, essa tese teve como objetivos: (i) estimar simultaneamente o efeito das três RP sobre o TEPT utilizando um instrumento validado; e (ii) avaliar se há efeito indireto da ITP sobre o TEPT mediado pelo sentimento de culpa/vergonha. Utilizamos modelagem de equações estruturais para analisar dados de 3211 participantes do Rio de Janeiro e de São Paulo. Tratamos as RP como variáveis latentes, selecionando desconfundidores específicos para cada reação. Nossas exposições foram as RP, sendo TEPT o desfecho. Calculamos odds ratios e intervalos de confiança de 95%. Utilizamos o Bayesian Information Criterion para comparar o ajuste de modelos não aninhados. Quando analisadas separadamente, todas as RP alcançaram significância estatística. No entanto, apenas DP (ORDP=1,8; IC95%:1,3-2,4) e RFP (ORRFP=2,5; IC95%:1,8-3,4) permaneceram estatisticamente significativas quando incluímos as três reações em um modelo com seus respectivos desconfundidores e correlações entre elas. Os resultados sugeriram um possível efeito da ITP sobre o TEPT (ORITP=1,4; IC95%:1,0-1,9). As interações entre as RP não foram estatisticamente significativas. Ao investigarmos o sentimento de culpa/vergonha como mediador entre ITP e TEPT, o efeito indireto alcançou apenas significância estatística limítrofe (ORITP(TNIE)=1,1; IC95%:1,0-1,2). Os efeitos direto (ORITP(PNDE)=1,3; IC95%: 0,8-1,8) e total (ORITP(TE)=1,4; IC95%:0,9-1,9) para ITP perderam significância quando todas as RP, seus desconfundidores e correlações entre elas fizeram parte do mesmo modelo. As demais RP, no entanto, permaneceram estatisticamente significativas (ORDP=1,7; IC95%:1,3-2,3 e ORRFP=2,5; IC95%:1,8-3,4). Nossos resultados mostraram que a DP e as RFP aumentaram o risco de TEPT mesmo quando consideradas em conjunto. A ITP pode ter efeito sobre o risco de TEPT, mas esse achado deve ser interpretado com cautela devido a significância limítrofe dessa RP em nosso modelo final. Também não identificamos uma mediação significativa entre ITP e TEPT pelos sentimentos de culpa/vergonha. Contudo, a significância limítrofe encontrada para o efeito indireto demanda investigações adicionais. Nossos achados reforçam a ideia de que as reações peritraumáticas devem ser analisadas e compreendidas como ocorrências simultâneas. Também seria oportuno que estudos envolvendo culpa/vergonha, ITP e TEPT focalizassem traumas caracterizados por aprisionamento e impossibilidade de escapar, dado que estas experiências são apontadas como mais susceptíveis para desencadear a ITP. (AU)

Posttraumatic stress disorder (PTSD) is a debilitating condition that greatly impacts quality of life. Among several PTSD risk factors, peritraumatic reactions (PR) such as peritraumatic tonic immobility (PTI), dissociation (PD) and physical panic reactions (PPR) are some of the most investigated. However, several studies have assessed these PR separately, and the pathway connecting them to PTSD is not well understood. Therefore, this thesis aimed to: (i) simultaneously estimate the effect of the three PR on PTSD using a validated instrument; and (ii) assess if there is an indirect effect of PTI on PTSD mediated by feelings of guilt/shame. We used structural equation modelling to analyse data from 3211 participants from Rio de Janeiro and São Paulo. We treated the PR as latent variables and selected specific confounders for each reaction. Our exposures were the PR, and PTSD was the outcome. We calculated odds ratios and 95% confidence intervals for each analysis. We also employed the Bayesian Information Criterion to compare the goodness of fit between non-nested models. Separately, all PR achieved statistically significant results. However, only PD (ORPD=1.8; 95%CI:1.3-2.4) and PPR (ORPPR=2.5; 95%CI:1.8-3.4) remained statistically significant when all three were included in a model with their respective confounders and correlations among all PR. Our findings suggested a possible effect of PTI on PTSD (ORPTI=1.4; 95%CI:1.0-1.9). Interactions between the PR were not statistically significant. When we investigated feelings of guilt/shame as the mediator between PTI and PTSD, the indirect effect achieved a borderline statistical significance (ORPTI(TNIE)=1.1; 95%CI:1.0-1.2). Direct (ORPTI(PNDE)=1.3; 95%CI:0.8-1.8) and total (ORPTI(TE)=1.4; 95%CI:0.9-1.9) effects lost their significance when all PR, their confounders and correlations were included in the same model. The other PR remained statistically significant (ORPD=1.7; 95%CI:1.3-2.3 and ORPPR=2.5; 95%CI:1.8-3.4). Our findings showed PD and PPR to increase the risk of PTSD even when considered in tandem. PTI could have an effect on PTSD, but this must be considered cautiously, as this PR only reached borderline significance in our final model. Feelings of guilt/shame did not significantly mediate PTI's effect on PTSD. However, a borderline statistical significance in the indirect effects warrants further investigation. Our findings reinforce the hypothesis that peritraumatic reactions should be analysed and understood as simultaneous occurrences, not as separate entities. It would also be appropriate for studies concerning guilt/shame, PTI and PTSD to focus on traumas characterized by imprisonment and feelings of inescapability, given that these experiences are allegedly more likely to trigger PTI.

Antecedente de depresión, síntomas de estrés postraumático, apoyo social percibido: prediciendo la depresión posparto / History of depression, post-traumatic stress symptoms, perceived social support: predicting postpartum depression

Objetivo: Describir y analizar si el apoyo social percibido modera la relación entre antecedente de depresión (AD) o síntomas de trastorno de estrés postraumático (TEPT) y desarrollo de síntomas de depresión posparto (SDPP), evaluado prospectivamente. Método: Diseño longitudinal de tres tiempos: antes del parto (n = 458), primer mes posparto (n = 406) y tercer mes posparto (n = 426). Se utilizaron la Escala de Depresión Posparto de Edimburgo (EPDS), la Escala de Síntomas de Estrés Postraumático (PCL-C) y la Escala de Apoyo Social Percibido (MOS). Se realizó un análisis de ocho modelos jerárquicos de regresión lineal múltiple, por cada tiempo de evaluación en el estudio. Resultados: Se encontró una asociación significativa entre síntomas de TEPT y puntaje de SDPP en los tres tiempos. El apoyo social percibido es un factor protector significativo para los SDPP en los tiempos 1 y 2, mientras que el AD es un factor de riesgo significativo en los tiempos 2 y 3. Los resultados no apoyan las hipótesis de interacción. Conclusiones: El apoyo social es un factor protector significativo, que puede disminuir los SDPP; sin embargo, disminuye con el tiempo. El apoyo social no logra revertir la asociación de los síntomas de TEPT con el puntaje en SDPP.

Objective: Describe and analyze if the perceived social support moderates the relationship between depression history or post-traumatic stress disorder symptoms and the development of symptoms of postpartum depression, prospectively evaluated. Method: Longitudinal design of three times: before partum (n = 458), one month (n = 458) and 3 months postpartum (n = 458). The version of the Edinburgh Postnatal Depression Scale (EPDS), the version of the PTSD Checklist-Civilian Version (PCL-C), and the version of the Medical Outcomes Study Social Support Survey (MOS) were used. Analysis of eight hierarchical multiple linear regression models. Results: A significant association was found between symptoms of post-traumatic stress and postpartum depression, in the three times measured. The perceived social support variable was found to be a significant protective factor for perinatal depression in times 1 and 2, and history of depression was significant in times 2 and 3. The results do not support the interaction hypothesis. Conclusions: Social support is a significant protective factor, which can reduce the symptoms of postpartum depression, nevertheless the significance decreases over time. However, social support fails to reverse the association of post-traumatic stress disorder symptoms with symptoms of postpartum depression score.

Transtorno de Estresse Pós-traumático e funções executivas em adultos: uma revisão sistemática / Posttraumatic Stress Disorder and executive functions in adults: a systematic review / Trastorno de Estrés Postraumático y funciones ejecutivas en adultos: una revisión sistemática

O Transtorno do Estresse Pós-traumático (TEPT) é caracterizado por apresentar sintomas de desconforto e medo diante de situações diretas e/ou imaginadas em relação a experiências que ameaçam a integridade pessoal. As Funções Executivas (FE) são processos responsáveis pela análise de uma situação, tomada de decisão e ações voltadas à resolução de problemas. Sabe-se que o TEPT está associado a prejuízos em diferentes dimensões das FE. Deste modo, o presente estudo investigou a produção científica sobre o tema feita nos últimos 12 anos. Duzentos e três registros foram identificados e 18 deles cumpriram os critérios de inclusão. A avaliação das pesquisas incluídas nesta revisão apontou o comprometimento das funções executivas e a reabilitação neuropsicológica mostrou-se eficiente como estratégia de intervenção para adultos diagnosticados com TEPT. A ausência de informações sobre a intensidade dos sintomas presentes no TEPT foi uma limitação comum aos estudos encontrados nesta pesquisa.(AU)

Posttraumatic Stress Disorder (PTSD) is characterized by symptoms of uneasiness and fear when faced with direct and/or imagined situations related to experiences that threaten personal integrity. Executive Functions (EF) are processes defined by situational analysis, making decisions and taking actions to solve problems. It is known that PTSD is associated with dysfunctions in different dimensions of EF. Accordingly, the present study investigated the scientific production on the subject considering the last 12 years. A total of203 records were identified, with 18 of them meeting the inclusion criteria. The evaluation of the studies included in this review showed the impairment of EF and that neuropsychological rehabilitation has proven to be an efficient intervention strategy for adults diagnosed with PTSD. The absence of information about the intensity of symptoms present in PTSD was a common limitation of the studies found in this review.(AU)

Predictors of response to cognitive-behavioral therapy in patients with posttraumatic stress disorder: a systematic review / Preditores de resposta à terapia cognitivo-comportamental em pacientes com transtorno de estresse pós-traumático: uma revisão sistemática

OBJETIVO: O transtorno de estresse pós-traumático (TEPT) é um transtorno altamente prevalente e incapacitante. Mesmo quando tratado com uma intervenção de primeira linha, terapia cognitivo-comportamental (TCC), 45% dos pacientes continuam sofrendo desse transtorno. Portanto, conhecer os fatores que podem prever quem responderá à TCC seria de grande valor no tratamento desses pacientes. Por esse motivo, revisamos sistematicamente a literatura para identificar as variáveis que poderiam predizer a resposta à TCC em pacientes que sofrem de TEPT. MÉTODOS: Seguindo as diretrizes do PRISMA 2020, pesquisamos em banco de dados eletrônico como ISI Web of Science, Scopus, PsycINFO, MEDLINE e PTSDpubs até novembro de 2021. Dois autores conduziram independentemente a seleção do estudo e a extração de dados. Estudos que examinaram possíveis preditores de resposta à terapia, com amostra de adultos (18-65 anos) de ambos os sexos, com e sem comorbidades, foram considerados elegíveis. As características dos estudos foram sintetizadas em uma tabela. O risco de viés foi avaliado pela ferramenta de avaliação de qualidade de risco de viés da Cochrane. RESULTADOS: Vinte e oito estudos envolvendo 15 variáveis foram selecionados. Desses, oito mostraram baixo risco de viés, 19 mostraram algumas preocupações e um mostrou alto risco potencial de viés. A relação terapêutica foi a única variável considerada um preditor de boa resposta à terapia. Todas as outras variáveis apresentaram resultados conflitantes. CONCLUSÕES: A variável mais promissora, embora muito fraca cientificamente, é a relação terapêutica. Ensaios clínicos randomizados adicionais devem ser conduzidos para esclarecer o papel dessa variável como um preditor de resposta da TCC em pacientes com TEPT.

OBJECTIVE: Posttraumatic stress disorder (PTSD) is a highly prevalent and disabling disorder. Even when treated with the first-line intervention, cognitive-behavioral therapy (CBT), 45% of the patients continue suffering from this disorder. Therefore, knowing the factors that could foresee who will respond to CBT would be of great value to the treatment of these patients. Thus, we have systematically reviewed the literature to identify the variables that could predict response to CBT in patients suffering from PTSD. METHODS: Following the PRISMA 2020 guidelines, we searched the electronic databases ISI Web of Science, Scopus, PsycINFO, MEDLINE, and PTSDpubs until November 2021. Two authors have independently conducted study selection and data extraction. Studies that examined possible predictors of response to therapy on a sample of adults (18-65 years), both genders, with and without comorbidities were considered eligible. The characteristics of the studies were synthesized in a table. The risk of bias was assessed by the Cochrane risk of bias quality assessment tool. RESULTS: Twenty- -eight studies comprising 15 variables were selected. Among those, eight showed a low risk of bias, 19 showed some concerns, and one showed a high potential risk of bias. The therapeutic relationship was the only variable considered to be a predictor of a good response to therapy. All other variables showed conflicting results. CONCLUSIONS: The most promising variable, although scientifically weak, is the therapeutic relationship. Additional randomized clinical trials should be conducted to clarify the role of this variable as a predictor of response to CBT in patients with PTSD.

Mental health and influencing factors of military medical students during the normalization period of the epidemic prevention and control / 中华医学教育探索杂志

Objective:To investigate the level of psychological stress, anxiety and posttraumatic stress disorder (PTSD) of military medical students under the condition of normalized prevention and control of the epidemic.Methods:A total of 225 students from a military university were selected by random sampling method. Chinese perceived stress scale (CPSS), Perceived social support scale (PSSS), Self-rating anxiety scale (SAS) and PTSD Checklist-5 (PCL-5) were used to measure the mental health of the subjects and influencing factors. SPSS 26.0 was used to conduct independent sample t test and ANOVA analysis. Pearson correlation analysis was conducted, and multiple regression equation was used to further analyze the relationship between psychometric factors. Results:The SAS scores of 22.2% (50/225) of the subjects and PCL-5 scores of 30.7% (69/225) of the subjects reached the positive standard. The results of correlation analysis showed that the total score of PSSS was negatively correlated with CPSS ( r=-0.315, P<0.01), SAS ( r=-0.336, P<0.01) and PCL-5 ( r=-0.137, P<0.05) scores. The score of family support negatively predicted the level of psychological stress ( B=-0.595, P<0.001), anxiety ( B=-0.635, P<0.001) and PTSD level ( B=-0.769, P=0.006) of the students. Conclusion:Social support, especially family support, has a significant protective effect on psychological stress, anxiety and PTSD during the period of normalized prevention and control of the epidemic.

Methods and application status of neurofeedback training in promoting rehabilitation of neuropsychiatric disorders / 中华神经医学杂志

Neurofeedback training (NFT) is an important neuromodulation method that can produce certain plasticity in the central nervous system, and is expected to be an effective physical intervention method for rehabilitation of mental disorders. So far, there have been many studies on NFT promoting the rehabilitation of common mental disorders in the literature. For different mental disorders, there are different NFT training programs with different intervention effects and mechanisms. This paper focuses on the application of NFT in the rehabilitation of mental disorders, introduces the concept, process and common solutions of NFT, and focuses on the methods and applications of NFT to promote the rehabilitation of common mental disorders, and finally discusses the faced problems and future research trends, aiming to provide references for innovative research and clinical application of NFT to promote the rehabilitation of mental disorders.

Contextualizing migration and mental health in the post-COVID era

Background: The population of migrants all over the world is progressively rising. The major reasons for migration include the desire for self-actualization, moving to a place with more opportunities, tourism, and education, and escaping hardship and political unrest in the home country. In recent times climate change, insecurity, and economic hardship are top of the list. The global economy has suffered a major blow from the multiple waves of the lingering COVID-19 pandemic. To lessen the scourge of inflation and to restore economic stability, several countries are being forced to liberalize their immigration policies and therefore immigrants are welcomed in these nations. This review attempts to investigate how migration in the post-pandemic era affects migrants' mental health. Main Text: Migration and the COVID-19 epidemic both have beneficial and durable effects on the mental health of migrants and immigration laws have a direct impact on several health-related issues. Mental health disorders may develop at any point from the pre-migration phase to the post-migration settlement in the host nations. Factors such as host community, racism, marginalization, political climate, poor support, loss of social status, language barriers, undocumented status, climate change, mode of dressing in the host country, and several others may lead to mental health disorders among migrants. Unfortunately, there is limited access to care, and the services provided may not be culturally sensitive. Conclusion: Despite the benefits gotten from migration like financial benefits and economic development of the native country and the left behind family members, migration has enormous psychological complications which have to be attended to. Access to specialists who are trained to provide culturally sensitive interventions and implement outreach programs to introduce the services to the migrants' community should be encouraged.

Contributions from functional neuroimaging studies to the comprehension of traumatic child experiences: preliminary findings / Aportes de los estudios de neuroimagen funcional a la comprensión del trauma infantil: estudio preliminar

Abstract This study aimed to describe the cerebral activation patterns using fMRI (Functional Magnetic Resonance Imaging) technology in a sample of 15 children with Posttraumatic Stress Disorder (PTSD) and 7 with no PTSD. The study used a Quasi-experimental methodology where two experimental tasks were applied: an emotional face task and a version of an emotional Stroop task. The results point out differences in the group of PTSD on the processing of negative stimuli and changes in their frontal lobe activation. These preliminary results suggest that early traumatic experiences affect typical brain development patterns. And explicit and implicit variables involved in the traumatic experiences are discussed as a part of any intervention process.

Resumen El presente estudio tuvo como objetivo describir patrones de activación cerebral mediante una técnica de Imagen por resonancia magnética funcional -fMRI- (abreviatura en inglés de Functional Magnetic Resonance Imaging) en una muestra de niños con Trastorno de estrés postraumático (TEPT) y compararlos con un grupo de controles. Estudio cuasi-experimental en el que se tomó un grupo de 15 niños con TEPT y se comparó con un grupo de 7 niños sin TEPT. Se emplearon dos tareas experimentales: una prueba de caras y una versión del Stroop emocional. Los resultados preliminares, señalan diferencias en el procesamiento de estímulos, principalmente de carácter negativo en los niños con TEPT y cambios en los patrones de activación a nivel de estructuras frontales. Se concluye que el trauma a edad temprana afecta el curso normal del desarrollo cerebral y se evidencia la importancia de abordar los aspectos explícitos e implícitos asociados a la experiencia traumática como parte de la intervención.
