RESUMEN

OBJECTIVE: Post-traumatic stress disorder (PTSD) is triggered by traumatic events, but genetic vulnerability and a history of childhood trauma are additional factors that may increase the risk of PTSD. Thus, our study focused on exploring the interaction between genetic susceptibility, as assessed by polygenic risk score (PRS), and traumatic events. METHODS: We evaluated 68 women with PTSD who had been sexually assaulted and 63 healthy controls without a history of sexual assault. DNA was genotyped using the Infinium Global Screening Array (Illumina), and PRS analysis was performed using PRSice. Furthermore, logistic regression models were employed to examine the interaction between childhood trauma, traumatic life events, and PTSD-PRS and how they contribute to the risk of developing PTSD. RESULTS: We found a significant association between PRS, childhood trauma (p = 0.03; OR = 1.241), and PTSD. Additionally, an interaction was observed between PRS, traumatic life events, and childhood trauma, particularly relating to physical and emotional neglect (p = 0.028; OR = 1.010). When examining neglect separately, we found a modest association between emotional neglect and PTSD (p = 0.014; OR = 1.086). CONCLUSIONS: Our findings highlight the importance of considering genetic vulnerability and traumatic experiences in understanding the etiology of PTSD.

RESUMEN

Introduction: Attachment patterns are established during early childhood; however, extreme experiences throughout life may change this structure, either toward attachment security or insecurity. We analyzed changes in attachment dimensions in women with acute post-traumatic stress disorder (PTSD) following sexual assault, that were randomized to a 14-week treatment with either the medication sertraline or Interpersonal Psychotherapy. Methods: Seventy-four adult women who presented significant reduction in PTSD symptoms across the trial responded to the Revised Adult Attachment Scale at baseline, on week 8 of treatment, and at the end of the trial, on week 14. We fitted a generalized linear model to explain the attachment anxiety and avoidance scores at baseline. A generalized linear mixed model investigated how attachment dimensions changed over time. Socioeconomic data, treatment type, history of childhood trauma, and PTSD severity over the 14-week period were the considered covariates. Results: At baseline, attachment anxiety was associated with a history of early trauma. Attachment anxiety remained stable during the follow-up. Attachment avoidance, on the other hand, significantly increased from baseline to week 14. Higher avoidance was observed in patients with higher total PTSD scores and on the cluster of hyperarousal symptoms. Races other than White (black, mixed-race, or Asian) and younger age were associated with higher attachment avoidance. Discussion: Contrary to our expectations, attachment avoidance increased during follow-up, indicating changes in the interpersonal realm beyond the symptoms of PTSD.

RESUMEN

OBJECTIVE: To combine elements of a systematic review and critical review to produce best evidence synthesis for the treatament of GAD. METHOD: There was included systematic reviews, metanalysis, and randomized controlled trials. Descriptor used was "generalized anxiety disorder", resulting in 4860 articles and 7 other studies, of which 59 were selected. RESULTS: Antidepressants and benzodiazepines are indicated, as well as pregabalin. From, atypical antipsychotics quetiapine has been studied. Cognitive behavior therapy (third wave of behavioral and cognitive therapies) as well as individual CBT proven to be effective. CONCLUSION: There is extensive literature on many effective treatments for GAD. The present work summarizes the therapeutic possibilities, emphasizing those available in the Brazil. Further studies are still needed to compare other available medications, to assess psychotherapies in more depth, new treatments and specially to assess the ideal time for maintaining therapy.

RESUMEN

BACKGROUND: Tonic immobility (TI) is a reflexive, involuntary response that causes motor inhibition, vocal suppression, and analgesia. TI is elicited by extreme fear and perception of entrapment in a life-threatening situation. Research suggests that TI is a frequent peritraumatic response and may be related to subsequent posttraumatic stress disorder (PTSD). However, findings are mixed and, as of yet, no systematic or meta-analytic review examining associations between TI and PTSD has been published. OBJECTIVE: We systematically and meta-analytically reviewed the literature and investigated whether TI is associated with the development, severity, and course of PTSD. Additionally, we evaluated whether different types of traumatic events are differentially associated with TI, and whether TI severity differs according to sex. METHODS: A systematic literature search was conducted using Embase, PubMed, PsycINFO, and Scopus. Meta-analyses were performed on the included articles. RESULTS: We identified 27 eligible articles. We found a significant association between TI and PTSD symptom severity (r = 0.39, 95% CI: 0.34-0.44; p < .0001). TI was more severe among females (Cohen's d=0.37, 95% CI: 0.25-0.48; p < .0001) and was more often elicited in situations involving interpersonal violence. We found limited longitudinal data to perform a meta-analysis of the association between TI and the development and/or course of PTSD. However, the literature available seems to support the role of TI in both the development and course of PTSD. CONCLUSIONS: Peritraumatic TI is associated with PTSD symptom severity, occurs more often during interpersonal violence, and is more severe among females. More longitudinal research is needed to investigate the role of TI in psychopathology development and course.

RESUMEN

Introduction: Sexual assault and a history of childhood sexual abuse (CSA) are related to posttraumatic stress disorder (PTSD) development. Long interspersed nuclear elements (LINE-1) are transposable elements, and their methylation is used to infer DNA global methylation. DNA methylation can be affected by trauma exposition which in turn would be associated with PTSD. Thus, we investigated if the LINE-1 methylation pattern is related to PTSD symptoms in females with a history of CSA. Methods: This is a case-control study that examined, at baseline (W1), 64 women victims of sexual assault diagnosed with PTSD and 31 patients with PTSD who completed the 1-year follow-up (W2). Participants were categorized into two groups according to the presence of CSA (PTSDCSA+: NW1 = 19, NW2 = 10; PTSDCSA-: NW1 = 45, NW2 = 21). PTSD symptoms (re-experiencing, avoidance, hyperarousal, alterations in cognition/mood) were assessed using the Clinician-Administered PTSD Scale, and the history of CSA was assessed by the Childhood Trauma Questionnaire. LINE-1 methylation was measured in three sites (CpG1, CpG2, CpG3) located in the 5'UTR region using bisulfite conversion followed by pyrosequencing. Linear regression models were performed to test the relation between LINE-1 CpG sites methylation and PTSD symptoms. Results: We found a negative association between CpG2 methylation and hyperarousal symptoms among those in the PTSDCSA+ group in W1 (adjusted p = 0.003) compared to the PTSDCSA- group (p > 0.05). Still, no association was observed between other PTSD symptoms and other CpG sites. Further, in the longitudinal analysis, LINE-1 hypomethylation was no longer observed in PTSD participants exposed to CSA. Conclusion: Our findings suggest that LINE-1 methylation may help understand the relationship between trauma and PTSD. However, more studies are needed to investigate LINE-1 as an epigenetic marker of psychiatric disorders.

RESUMEN

INTRODUCTION: Sexual violence is one of the most severe traumatic events. It is associated with a higher risk for post-traumatic stress disorder (PTSD) development. Sleep disturbances such as insomnia are frequently reported by PTSD patients and play a key role in the development and course of the disorder. Sleep disturbances are associated with higher levels of pro-inflammatory cytokines emphasizing the importance of sleep studies in individuals with PTSD. OBJECTIVES: To investigate the association between subjective and objective sleep measurements and PTSD symptoms with inflammatory markers in women with PTSD following sexual assault. METHODS: In this longitudinal study fifty-seven women with PTSD were evaluated for sleep measurements and inflammatory markers. Participants completed the Clinician-Administered PTSD Scale, the Beck Depression Inventory, the Pittsburgh Sleep Quality Index (PSQI), and the Insomnia Severity Index. In addition, patients underwent full in-lab polysomnography and serum levels of interleukin (IL)-1ß, IL-6, tumor necrosis factor (TNF)-α, and C-reactive protein (CRP) measurement. All assessments were performed at baseline and after one year. Patients received pharmacological and/or psychological interventions between baseline and one-year follow-up. RESULTS: Despite improving PTSD symptoms severity and sleep quality (expressed in PSQI), we found an increase in the inflammatory markers IL-1ß, TNF-α, IL-6 and CRP after one year of follow-up. These findings suggest that neurobiological processes may advance independently of PTSD symptoms. We found a significant increase in the levels of IL-1ß and TNF-α associated with decreased slow-wave sleep (p = 0.019 and p = 0.018 respectively), IL-6 associated with arousal index (p = 0.024), and CRP associated with insomnia severity (p = 0.012), and sleep duration longer than 6 h per night (p < 0.001). CONCLUSIONS: Sleep impairments in PTSD may be associated with a gradual and persistent alteration in the immune system, resulting in a progressive inflammatory process. Our results suggest that sleep mechanisms are involved in this incident inflammatory process in young women with PTSD.

RESUMEN

INTRODUCTION: Lower adherence to antiretroviral treatment (ART) has been found among people with HIV (PWH) who have comorbid mental disorders like depression and alcohol use in Sub-Saharan African. However, there has been less exploration with regards to other mental disorders. METHODS: This study assessed the association of multiple mental disorders and adherence to ART based on the data from primary/tertiary health care facilities in Maputo and Nampula, Mozambique. We administered a sociodemographic questionnaire, Mini International Neuropsychiatric Interview (MINI) Plus 4.0.0 adapted for use in Mozambique to assess mental conditions, and a 3-item self-report to measure ART adherence. RESULTS: 395 HIV-positive (self-report) participants on ART, with an average age of 36.7 years (SD = 9.8), and 30.4% were male. The most common mental disorders were major depressive disorder (27.34%) followed by psychosis (22.03%), suicidal ideation/behavior (15.44%), and alcohol-use disorder (8.35%). Higher odds of missing at least one dose in the last 30 days (OR = 1.45, 95% CI: 1.01, 2.10) were found in participants with any mental disorder compared to those without a mental disorder. The highest levels of non-adherence were observed among those with drug use disorders and panic disorder. CONCLUSIONS: In Mozambique, PWH with any co-occurring mental conditions had a lower probability of ART adherence. Integrating comprehensive mental health assessment and treatment and ART adherence interventions tailored to PWH with co-occurring mental disorders is necessary to attain optimal ART adherence and reach the UNAIDS ART target.

RESUMEN

Background: During the COVID-19 pandemic, health-care workers (HCWs) may have been confronted with situations that may culminate in moral injury (MI). MI is the psychological distress that may result from perpetrating or witnessing actions that violate one's moral codes. Literature suggests that MI can be associated with mental health problems.Objective: We aimed to meta-analytically review the literature to investigate whether MI is associated with symptoms of posttraumatic stress disorder (PTSD), anxiety, depression, burnout, and suicidal ideation among active HCWs during the COVID-19 pandemic.Method: We searched eight databases for studies conducted after the onset of the COVID-19 pandemic up to 18 July 2023, and performed random-effects meta-analyses to examine the relationship between MI and various mental health outcomes.Results: We retrieved 33 studies from 13 countries, representing 31,849 individuals, and pooled 79 effect sizes. We found a positive association between MI and all investigated mental health problems (rs = .30-.41, all ps < .0001). Between-studies heterogeneity was significant. A higher percentage of nurses in the samples was associated with a stronger relationship between MI and depressive and anxiety symptoms. Samples with a higher percentage of HCWs providing direct care to patients with COVID-19 exhibited a smaller effect between MI and depressive and anxiety symptoms. We observed a stronger effect between MI and PTSD symptoms in US samples compared to non-US samples.Conclusion: We found that higher MI is moderately associated with symptoms of PTSD, anxiety, depression, burnout, and suicidal ideation among HCWs during the COVID-19 pandemic. Our findings carry limitations due to the array of MI scales employed, several of which were not specifically designed for HCWs, but underscore the need to mitigate the effect of potentially morally injurious events on the mental health of HCWs.


We conducted the first meta-analysis of moral injury and mental health among healthcare workers.Moral injury is moderately associated with symptoms of PTSD, depression, anxiety, burnout, and suicidal ideation.There was a stronger association between MI and anxiety and depressive symptoms for samples with more nurses.

RESUMEN

Racial discrimination (RD) is unfair treatment of individuals based on race or ethnicity. It is a pervasive and increasing phenomenon in the lives of many individuals with deleterious effects on mental health. Research implicates RD in diminished well-being, lower life satisfaction and self-esteem, and mental health disorders. Furthermore, there have been reports that minorities and marginalized groups exposed to RD are at a higher risk of suicide. Given that RD negatively impacts mental health and that suicide is a major public health concern, we meta-analytically reviewed the literature to investigate whether RD is associated with suicidal ideation (SI) and suicide attempt (SA). We identified 43 eligible articles investigating the association between RD and suicidality through PubMed, Embase, PsycINFO and Scopus, from which we pooled 39 effect sizes for SI (58,629 individuals) and 15 for SA (30,088 individuals). Results demonstrated that RD has a small but significant effect both on SI (r = 0.16, 95% CI: 0.12 to 0.19; p < 0.0001) and on SA (r = 0.13, 95% CI: 0.02 to 0.23; p = 0.018). We found no indication of publication bias, and fail-safe tests confirmed the robustness of the results. Furthermore, we tested the moderating effects of several study characteristics (e.g., age, race, RD and SI time frame assessment, and categorization of RD measures). The only study characteristic to moderate the effect of RD on SI was SI time frame assessment (r = 0.07; 95% CI: 0.015 to 0.12; p = 0.01). Our findings suggest that SI and SA are phenomena that may be influenced by exposure to RD. Thus, individuals that are discriminated based on race may develop more suicidal thoughts and an increased likelihood of attempting suicide. These findings underscore the need for more prevention and intervention efforts to attenuate the effect of RD on suicidality.

RESUMEN

Telomeres are short tandem repeats of "TTAGGG" that protect the chromosome ends from deterioration or fusion of chromosomes. Their repeat length shortens with cell division acting as a biomarker of cellular aging. Traumatic stress events during adulthood or childhood have been associated with posttraumatic stress disorder (PTSD) and short leukocyte telomere length (LTL). This study investigated whether LTL was associated with PTSD in a Brazilian sample of sexually assaulted civilian women at two time points: baseline and 1-year follow-up. At baseline, we assessed 64 women with PTSD following sexual assault (cases) and 60 women with no previous history of sexual trauma or mental disorders (healthy controls - HC). At follow-up visit, 13 persistent PTSD cases, 11 HCs, and 11 PTSD remitters patients were evaluated. PTSD diagnosis and severity were assessed using Mini International Neuropsychiatric Interview (Diagnostic and Statistical Manual of Mental Disorders III/IV criteria) and Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), respectively. LTL was measured using multiplex real-time polymerase chain reaction (PCR). In the baseline analysis, we observed that LTL was associated with re-experiencing symptoms (B = -0.16; confidence interval (CI) 95% = -0.027--0.005; Bonferroni-adjusted p-value = 0.02), but no association was observed between other PTSD symptoms and LTL. In the longitudinal analysis, telomere shortening was no longer observed in patients with PTSD and PTSD remitters. In conclusion, our findings indicate that shorter baseline LTL is associated with early stage of PTSD re-experiencing symptoms in recently sexually assaulted women.

RESUMEN

Esta pesquisa foi desenvolvida a partir do projeto temático "Transtorno de estresse pós-traumático e neuroprogressão: trauma e estresse no aumento da carga alostática e aceleração do processo de envelhecimento", realizado com mulheres vítimas de violência sexual e que desenvolveram estresse pós-traumático no estado de São Paulo. Neste estudo, são apresentados relatos de violência sexual na infância e na adolescência e sua reexposição na vida adulta e, com isso, tem como objetivo trazer à luz compreensões acerca dessa vivência a fim de abrir possibilidades de intervenções adequadas. Foram realizadas entrevistas reflexivas com quatro colaboradoras que, na triagem do Projeto Temático, responderam positivamente a um questionário de abuso e negligência durante a infância e na adolescência. Na análise fenomenológica, seus discursos foram separados em oito categorias de sentido (Afeto, Culpa, Mundo familiar, Não dito, Racismo, Profissionais, Hoje e Reexposição à violência sexual). Concluiu-se que a violência sexual diz respeito a uma responsabilidade política, uma vez que as colaboradoras culpam-se por acreditarem que a vulnerabilidade delas reside em algum comportamento provocado por elas mesmas e não por mais um dispositivo de violência contra a mulher.


This paper was developed based upon a thematic project "Posttraumatic stress disorder and neuroprogression: trauma and stress increasing load allostatic and accelerating the aging process", conducted with women who suffered sexual assault and developed post-traumatic stress disorder in the state of São Paulo. This study has reports about sexual violence in childhood and adolescence and its re-exposures in adulthood and seeks to bring up understandings about this experience in order to open possibilities for a more appropriate intervention. Reflective interviews were made with four collaborators that previously answered positively to a questionnaire of abuse and neglect during childhood and adolescence in the screening of the Thematic Project. With the phenomenological analysis their speech was split into eight categories (Affections, Guilt, Familiar world, Unsaid, Racism, Health professionals, Today and Sexual violence re-exposure). It has been concluded that sexual violence concerns to a political responsibility, once the collaborators blamed themselves for they believe that their vulnerability was their fault instead of a tradition of gender violence.


Esta investigación se desarrolló a partir del proyecto temático "Trastorno de estrés postraumático y neuroprogresión: el trauma y el estrés en el aumento de la carga alostática y la aceleración del proceso de envejecimiento", realizado con mujeres víctimas de violencia sexual y que desarrollaron estrés postraumático, en el estado de São Paulo. En este estudio, se presentan relatos de violencia sexual en la infancia y en la adolescencia y su reexposición en la edad adulta y, con ello, se pretende sacar a la luz comprensiones acerca de esa experiencia, para abrir posibilidades de intervenciones adecuadas. Se realizaron entrevistas reflexivas con cuatro colaboradoras que, en el triaje del Proyecto Temático, respondieron positivamente a un cuestionario sobre abuso y negligencia en la infancia y la adolescencia. En el análisis fenomenológico, sus discursos se separaron en ocho categorías de sentido (Afecto, Culpa, Mundo Familiar, No Dicho, Racismo, Profesionales, Actualidad y Reexposición a la Violencia Sexual). Se concluyó que la violencia sexual tiene que ver con una responsabilidad política patriarcal, ya que las colaboradoras se culpan a sí mismas por creer que su vulnerabilidad radica en algún comportamiento causado por ellas mismas y no por más un dispositivo de violencia contra las mujeres.

RESUMEN

This proof-of-concept study aimed to investigate the viability of a predictive model to support posttraumatic stress disorder (PTSD) staging. We performed a naturalistic, cross-sectional study at two Brazilian centers: the Psychological Trauma Research and Treatment (NET-Trauma) Program at Universidade Federal of Rio Grande do Sul, and the Program for Research and Care on Violence and PTSD (PROVE), at Universidade Federal of São Paulo. Five supervised machine-learning algorithms were tested: Elastic Net, Gradient Boosting Machine, Random Forest, Support Vector Machine, and C5.0, using clinical (Clinician-Administered PTSD Scale version 5) and sociodemographic features. A hundred and twelve patients were enrolled (61 from NET-Trauma and 51 from PROVE). We found a model with four classes suitable for the PTSD staging, with best performance metrics using the C5.0 algorithm to CAPS-5 15-items plus sociodemographic features, with an accuracy of 65.6% for the train dataset and 52.9% for the test dataset (both significant). The number of symptoms, CAPS-5 total score, global severity score, and presence of current/previous trauma events appear as main features to predict PTSD staging. This is the first study to evaluate staging in PTSD with machine learning algorithms using accessible clinical and sociodemographic features, which may be used in future research.

RESUMEN

Objective: Improved understanding of the time course of neural changes associated with adolescent PTSD would elucidate the development of the disorder and could inform approaches to treatment. We compared hippocampal volumes and resting state functional connectivity (RSFC) in adolescent girls with post-traumatic stress disorder (PTSD) secondary to sexual assault, within six months of onset and age- and gender-matched, non-trauma exposed healthy controls (HCs) in São Paulo, Brazil. We also examined the relationship between pre- and post-treatment PTSD symptoms and RSFC. Method: We collected brain structure, RSFC, and PTSD symptoms in 30 adolescents with PTSD (mean age: 15.7 ± 1.04 years) and 21 HCs (mean age: 16.2 ± 1.21 years) at baseline. We collected repeated measures in 21 participants with PTSD following treatment; 9 participants dropped out. Hippocampal volume and RSFC from hippocampal and default mode network (DMN) seeds were compared between participants with PTSD and HCs. We examined associations between within-subject changes in RSFC and PTSD symptoms following treatment. Results: No hippocampal volumetric differences between groups were found. Compared to HCs, adolescents with recent PTSD had reduced RSFC between hippocampus and the lateral parietal node of the DMN, encompassing the angular gyrus, peak coordinates: -38, -54, 16; 116 voxels; peak F 1,47 = 31.76; FDR corrected p = 0.038. Improvements in PTSD symptoms were associated with increased RSFC between hippocampus and part of the lateral parietal node of the DMN, peak coordinates: -38, -84, 38; 316 voxels; peak F 1,47 = 40.28; FDR corrected p < 0.001. Conclusion: Adolescents with recent PTSD had reduced hippocampal-DMN RSFC, while no group differences in hippocampal volume were found, suggesting that hippocampal function, but not structure, is altered early in the course of PSTD. Following treatment, hippocampal-DMN RSFC increased with symptom improvement and may indicate an important neural mechanism related to successful PTSD treatment.

RESUMEN

A growing body of research demonstrates the association between neighborhood context and health. The underlying biological mechanisms of this association are not fully understood. We conducted a systematic review of studies that investigated the association between neighborhood context and telomere length (TL), a DNA-protein complex that shortens after cell division. Short TL is linked to age-related diseases and may be impacted by chronic stress. Nineteen eligible articles identified through PubMed and Scopus met inclusion criteria. Results demonstrated inconsistent support for the relationship between neighborhood disadvantage and short TL. However, findings across several studies provide evidence for an inverse association between perceived neighborhood problems and TL, suggesting that TL may be an important factor in understanding health vulnerabilities associated specifically with negative perceptions of the neighborhood context.

RESUMEN

Background: Most posttraumatic stress disorder (PTSD) sleep disturbances reports have been conducted in male combat veteran populations, usually decades after the disorder's onset. Given the increase in the prevalence of violence against women and the fact that women are at greater risk for developing PTSD, it is critical to examine sleep abnormalities in this population. Objectives: To examine subjective and objective sleep quality in young women with PTSD following sexual assault compared with a control group at baseline and after one year of treatment. Methods: Seventy-four women with PTSD following sexual assault and 64 healthy controls with no history of sexual assault were assessed using the Clinician-Administered PTSD Scale (CAPS-5), the Beck Depression Inventory, the Beck Anxiety Inventory, the Pittsburgh Sleep Quality Index (PSQI), the Modified Fatigue Impact Scale, and the Insomnia Severity Index. Subjects also underwent full in-lab polysomnography. PTSD participants received pharmacological and/or psychological therapy between baseline and one-year follow-up. Results: The PTSD group had significantly higher scores in the clinical and sleep measurements than the control group. Although the PTSD group reported poorer subjective sleep quality than healthy controls, there were few between-group differences in objective sleep. Analysis of the PTSD group at baseline and one-year follow-up showed that the PSQI global score was a significant predictor of PTSD improvement. Conclusions: Sleep quality is impaired in young women with PTSD and may impact long-term treatment responses. Better sleep quality is significantly associated with PTSD improvement, independent of depression and anxiety.


Antecedentes: la mayoría de los reportes de trastornos del sueño en el trastorno por estrés postraumático (TEPT) se han realizado en poblaciones de hombres veteranos de guerra, generalmente décadas después del inicio del trastorno. Dado el aumento en la prevalencia de la violencia contra las mujeres y el hecho de que las mujeres tienen un mayor riesgo de desarrollar TEPT, es fundamental examinar las anomalías del sueño en esta población.Objetivos: Examinar la calidad del sueño subjetiva y objetiva en mujeres jóvenes con trastorno de estrés postraumático después de una agresión sexual en comparación con un grupo control al inicio y después de un año de tratamiento.Métodos: Se evaluaron 74 mujeres con TEPT después de agresión sexual y 64 controles sanos sin antecedentes de agresión sexual utilizando la Escala de TEPT administrada por un médico (CAPS-5, en su sigla en inglés), el Inventario de Depresión de Beck, el Inventario de Ansiedad de Beck, la Calidad del Sueño de Pittsburgh. (PSQI, en su sigla en inglés), la escala de impacto de fatiga modificada y el índice de gravedad del insomnio. Los sujetos también se sometieron a una polisomnografía completa en el laboratorio. Los participantes con TEPT recibieron terapia farmacológica y/o psicológica entre el inicio y el seguimiento al año.Resultados: El grupo de TEPT tuvo puntuaciones significativamente más altas en las mediciones clínicas y del sueño que el grupo de control. Aunque el grupo de TEPT reportó una peor calidad del sueño subjetivo que los controles sanos, hubo pocas diferencias entre grupos en el sueño objetivo. El análisis del grupo de TEPT al inicio y al año de seguimiento mostró que la puntuación global del PSQI fue un predictor significativo de la mejoría del TEPT.Conclusiones: La calidad del sueño se ve afectada en mujeres jóvenes con TEPT y puede afectar las respuestas al tratamiento a largo plazo. Una mejor calidad del sueño se asocia significativamente con la mejora del TEPT, independientemente de la depresión y la ansiedad.

RESUMEN

Objectives: The aim of this study was to validate CAPS-5 for the Brazilian-Portuguese language on a sample of 128 individuals from two centers (from the cities of São Paulo and Porto Alegre) who have been recently exposed to a traumatic event. Methods: We performed a reliability analysis between interviewers (with a subset of 32 individuals), an internal consistency analysis, and a confirmatory factorial analysis for the validation study. Results: The inter-rater reliability of the total PTSD symptom severity score was high [intraclass correlation coefficient =0.994, 95% CI (0.987-0.997), p < 0.001]. Cohen's Kappa for individual items ranged between 0.759 and 1. Cronbach's alpha coefficients indicated high internal consistency for the CAPS-5 full scale (α = 0.826) and an acceptable level of internal consistency for the four symptom clusters. The confirmatory factorial analysis for the 20-item original CAPS-5 did not fit the data well. A 15-item model with better results was then established by excluding the following CAPS-5 items: dissociative amnesia, recklessness, distorted cognitions, irritability, and hypervigilance. Conclusion: Despite the limitation of the predominance of female victims, and the high number of sexually assaulted women in our sample, the model with only 15 items provided a good fit to the data with high internal consistency (α = 0.835).

RESUMEN

BACKGROUND: Posttraumatic stress disorder (PTSD) is a prevalent, chronic, and severe disorder related to traumatic events. Women are disproportionately affected by PTSD than men and are more at risk in the occurrence of sexual assault victimization. Estimates suggest that 50% of women develop PTSD following sexual assault and successful clinical management can be challenging. Growing evidence has implicated neural, immune, and endocrine alterations underpinning PTSD, but only few studies have assessed the evolution of acute PTSD in women. OBJECTIVE: This study aims to measure whether the onset of PTSD is associated with accelerated aging in women following sexual assault. We hypothesize that the increase of allostatic load caused by PTSD leads to neuroprogression. We will implement a randomized clinical trial to compare responses to treatment with either interpersonal psychotherapy adapted for PTSD (IPT-PTSD) or the selective serotonin reuptake inhibitor sertraline. METHODS: We will include women between 18 and 45 years of age, who experienced sexual assault from 1 to 6 months before the initial evaluation, and present with a Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) diagnosis of PTSD. Baseline evaluation will comprise clinical and psychometric assessments, structural and functional magnetic resonance imaging, neuropsychological testing, polysomnography, evaluation of immune and endocrine parameters, and genetic analyses. Age-matched female healthy controls will be included and subjected to the same evaluation. Patients will be randomized for treatment in 1 of the 2 arms of the study for 14 weeks; follow-up will continue until 1 year after inclusion via treatment as usual. The researchers will collect clinical and laboratory data during periodic clinical assessments up to 1-year follow-up. RESULTS: Data collection started in early 2016 and will be completed by the end of the first semester of 2020. Analyses will be performed soon afterward, followed by the elaboration of several articles. Articles will be submitted in early 2021. This research project has obtained a grant from the Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP 2014/12559-5). CONCLUSIONS: We expect to provide insight into the consequences of recent sexual assault exposure in women by investigating the degree of neuroprogression developing from an early stage of PTSD. We also expect to provide important evidence on the efficacy of a non-exposure psychotherapy (IPT-PTSD) to mitigate PTSD symptoms in recently sexually assaulted women. Further, we aim to obtain evidence on how treatment outcomes are associated with neuroprogression measures.

RESUMEN

Discrimination is unfair treatment against a certain group based on race, age, gender, sexual orientation, or other social identities. Discrimination is pervasive in society, elevates psychosocial stress, and is associated with negative mental and physical health outcomes. However, more research is needed to understand the biological mechanisms underlying discrimination-related health disparities. Telomere science may contribute to elucidate some of these aspects. Telomeres are protein-DNA complexes that shorten after cell division and are valuable markers of cellular aging. Short telomeres have been associated with the onset of age-related diseases. Evidence shows that chronic psychological stress may accelerate telomere shortening. Since discrimination can lead to psychological strain with cumulative impact on general health, we hypothesized that groups that report more discrimination show reduced telomere length (TL) as a consequence of psychosocial stress elevation. Through a systematic review of the literature we found 12 articles that met our criteria. Eligible studies measured racial, gender, unfair policing, and multiple forms of discrimination in association with TL. Our review showed mixed results, suggesting that there is weak evidence of a main association between discrimination and TL. However, discrimination may interact with several variables (such as depressive symptoms, acculturation, higher socioeconomic status, internalization of negative racial bias, and not discussing discrimination experiences with others) and contribute to shorten telomeres. Discrimination is a complex social construct composed of a vast sum of experiences, impressions, and contexts that in combination with other sources of stress may have an impact on TL. Telomeres may be a plausible pathway to investigate health discrepancies in discriminated groups in society, but more evidence is needed to investigate the potential harm of discrimination on cells.

RESUMEN

BACKGROUND: This study investigated the patterns of comorbidity between PTSD and depression, other anxiety disorders, alcohol-related disorders using the DSM-IV and ICD-10 criteria. The temporal sequence of the comorbid diagnoses was also investigated. METHODS: We used data from a large population-based survey carried out between 2007 and 2008 in the two largest cities in Brazil: São Paulo and Rio de Janeiro. RESULTS: Diagnoses of depression, other anxiety disorders, and alcohol-related disorder were more prevalent in the people with PTSD than in those without PTSD. Using the DSM-IV criteria, approximately 67% of cases presenting PTSD were also diagnosed with another mental disorder. The diagnosis category of other anxiety disorders presented the highest proportion of comorbidity (53%). Depression was found in 34% person with PTSD whilst alcohol-related disorders were observed in 7%. Considering the temporal relationship, the onset of comorbid depression was uniformly distributed through the periods before, within the same year and after PTSD's onset. When other anxiety disorders were comorbid with PTSD, in almost 90% of the cases the other anxiety disorders preceded PTSD. For comorbidity between of alcohol-related disorders and PTSD, in 50% of the cases alcohol-related disorders preceded the diagnosis of PTSD. LIMITATIONS: The cross-sectional design imposes limitations on establishing a temporal relationship between the onset of psychiatric disorders due to memory bias. CONCLUSIONS: Our findings indicate that among individuals presenting comorbid PTSD and other anxiety disorders, this diagnosis tend to precede PTSD. Comorbid cases are more frequent and more severe, and this should be taken into account in therapeutic research and clinical practice.

RESUMEN

O Transtorno de Estresse Pós-Traumático (TEPT) é frequentemente associado a déficits cognitivos, porém ainda existem divergências com relação as funções cognitivas afetadas. O objetivo do presente estudo foi avaliar o impacto do TEPT na memória operacional, na memória visual de curto prazo, na memória episódica de longo prazo, na memória semântica de longo prazo e na memória prospectiva. A amostra foi composta por 20 mulheres com idades entre 20 e 60 anos, sendo 10 mulheres provenientes do Programa de Atendimento e Pesquisa em Violência da Universidade Federal de São Paulo (PROVE) com diagnóstico de TEPT (GTEPT) e 10 mulheres controle com a mesma idade e escolaridade (GC). O instrumento utilizado foi o Instrumento de Avaliação Neuropsicológica Breve (NEUPSILIN). Os dados foram analisados por teste t de Student para amostras dependentes e o nível de significância adotado foi de 5%. Os resultados obtidos a partir da análise do NEUPSILIN apontam para prejuízos na memória operacional (p = 0,04) e na memória prospectiva (p = 0,02) associados ao TEPT. Porém não foram observadas diferenças entre os grupos no que diz respeito aos outros tipos de memória investigados (p > 0,05). Os achados deste estudo, com relação aos prejuízos na memória operacional e na memória prospectiva associados ao TEPT estão de acordo com a literatura. Ambas funções são de extrema importância para o desempenho de atividades cotidianas, portanto, a intervenção e reabilitação destas funções no sujeito com TEPT podem auxiliar significativamente na melhora da qualidade de vida....(AU)


Posttraumatic Stress Disorder (PTSD) is often associated with cognitive deficits, but there are still some differences regarding cognitive functions affected. Therefore, the aim of this study was to evaluate the impact of PTSD on working memory, visual shortterm memory, long-term episodic memory, long-term semantic memory and prospective memory. The sample consisted of 20 women aged between 20 and 60 years, ten women from the Program of Assistance and Research on Violence of the Federal University of São Paulo (PROVE) diagnosed with PTSD and overlapping violence (GTEPT) and ten women control of the same age and educational level (GC). The instrument used was the Brief Neuropsychological Assessment Instrument (NEUPSILIN). Data were analyzed by Student's t-test for dependent samples, and the significance level was 5%. The results obtained from the analysis NEUPSILIN point to the losses in working memory (p = 0.04) and prospective memory (p = 0.02) associated with PTSD. Differences between groups were not observed on other types of memory investigated (p > 0.05). The findings of this study on losses in working memory and prospective memory associated with PTSD are in agreement with the literature. Both functions are critical to the performance of daily activities. Therefore, intervention and rehabilitation of these functions in the subject with PTSD can help significantly in improving the quality of life....(AU)
