Posttraumatic stress disorder (PTSD) and depression severity in sexually assaulted women: hypothalamic-pituitary-adrenal (HPA) axis alterations.

BACKGROUND: Sexual assault is implicated in several adverse psychological and physical health outcomes, including posttraumatic stress disorder (PTSD) and depression. Neurobiological research has shown variations related to the hypothalamic-pituitary-adrenal (HPA) axis, immune alterations, metabolic function, and brain circuitry. Although these mechanisms have been extensively studied, the results have demonstrated different outcomes in PTSD. METHODS: We compared the plasma adrenocorticotropin (ACTH) and salivary cortisol levels of fifty-eight women with PTSD developed after sexual assault to those of forty-four female controls with no history of trauma. We also evaluated the psychiatric diagnosis and symptom severity of PTSD and depression. The participants' clinical conditions were associated with their hormonal levels to assess whether symptom severity was related to hormonal imbalance. RESULTS: A large percentage of sexually assaulted women had PTSD and comorbid depression. The ACTH levels were higher in the PTSD group than the control group and increased as PTSD severity increased, considering depressive symptoms, measured by the Beck Depression Inventory (BDI) (p < 0.0001), as well as PTSD symptoms, measured by subscale D of the Clinician-Administered PTSD Scale (CAPS-5) (p = 0.045) and the CAPS-5 total scale (p = 0.026). Cortisol levels measured at 10 pm were higher for the PTSD group than the control group (p = 0.045, p = 0.037, respectively), and the cortisol awakening response showed elevated cortisol levels for the PTSD group. CONCLUSIONS: These results show a correlation between symptom severity and HPA axis imbalance in patients with PTSD. Elevated ACTH and an elevated cortisol response in patients with comorbid depressive symptoms were the opposite of the expected response for patients with PTSD only. This association leads to the hypothesis that the neurobiological alterations of PTSD are related to the type of symptoms presented and their severity. These manifestations likely influence the disease course, prognosis and response to treatment. These outcomes highlight the need to discuss particular neurobiological alterations in patients with PTSD developed after sexual assault, mainly those with severe depressive symptoms.

Task shifting interpersonal counseling for depression: a pragmatic randomized controlled trial in primary care.

BACKGROUND: Task shifting approaches (rational redistribution of tasks among health workforce teams) to train lay professionals to assist with integrating mental health treatment in primary care has been recommended to close the mental health treatment gap for depression in low- and middle-income countries. This study aims to examine the a new model for depression care in a low-resource environment compared to enhanced treatment at usual (E-TAU). METHODS: We trained non-specialist community health workers (local lay employees of the public health system) to provide Interpersonal Counseling (IPC) to treat depressive symptoms in the Brazilian, São Paulo city, family health strategy (FHS). We conducted a randomized controlled trial involving 86 patients with a current major depressive disorder or dysthymia (based on DSM-IV) recruited from an FHS clinic. Participants were randomized to IPC intervention (n = 43) or E-TAU (n = 43). Participants allocated to IPC received 3-4 sessions provided by community health workers; research psychologists followed the E-TAU participants to facilitate their referral to specialized mental health care within the public system. Reduction of depressive symptoms was assessed using the Hamilton Rating Scale (HDRS-17) and the Patient Health Questionnaire (PHQ-9); minor psychiatric symptomatology (including depression, anxiety and somatoform symptoms) were measured using the Self Reporting Questionnaire (SRQ); and functioning was measured by the Clinical Global Impression Scale over a 2-month period. RESULTS: Intention-to-treat analysis showed significant improvement on symptoms for both groups over 2 months, without significant differences between them. Per-protocol analysis showed significant better HDRS-17 outcomes for the IPC group. CONCLUSIONS: Training non-specialist community health workers in low- and middle-income countries to provide IPC could be a successful strategy in reducing the burden of depression and also potentially a low-cost and effective alternative to specialist-led services that might not be possible in low income settings.

Mental health of children who work on the streets in Brazil after enrollment in a psychosocial program.

PURPOSE: To evaluate the mental health status of children working on the streets in Sao Paulo City, Brazil, two years after their participation in a psychosocial program, and to identify factors associated with their mental health status. METHODS: From a total sample of 126 children working on the streets, 107 (85%) were re-evaluated two years after the initiation of a psychosocial program which aimed to cease their work on the streets. The focus was the presence of mental health problems, defined based on a screening instrument (Strengths and Difficulties Questionnaire). Logistic regression models tested factors related to the probability that a child would not present mental health problems at follow-up. RESULTS: The likelihood of a child presenting mental health problems was higher at baseline compared to the two-year follow-up (67.5 and 56.1%, respectively). Absence of mental health problems two years after a psychosocial intervention was significantly correlated with the following baseline factors: lower level of caregiver's psychiatric symptoms as measured by the SRQ (Self-Report Questionnaire) (AOR = 0.84, p = 0.0065), absence of child physical neglect (AOR = 0.38, p = 0.0705) and parental Protestant religion affiliation, compared to other religions (AOR = 4.06; p = 0.0107). CONCLUSIONS: Different factors are related to the absence of mental health problems of children working on the streets after enrollment in a two-year psychosocial program. Our findings suggest that interventions that aim to improve child mental health should consider the detection of psychiatric symptoms in caregivers, provide treatment when it is needed, and also assess other problems such as neglect in the family setting.

Does pediatric post-traumatic stress disorder alter the brain? Systematic review and meta-analysis of structural and functional magnetic resonance imaging studies.

Several studies have recently demonstrated that the volumes of specific brain regions are reduced in children and adolescents with post-traumatic stress disorder (PTSD) compared with those of healthy controls. Our study investigated the potential association between early traumatic experiences and altered brain regions and functions. We conducted a systematic review of the scientific literature regarding functional magnetic resonance imaging and a meta-analysis of structural magnetic resonance imaging studies that investigated cerebral region volumes in pediatric patients with PTSD. We searched for articles from 2000 to 2014 in the PsycINFO, PubMed, Medline, Lilacs, and ISI (Web of Knowledge) databases. All data regarding the amygdala, hippocampus, corpus callosum, brain, and intracranial volumes that fit the inclusion criteria were extracted and combined in a meta-analysis that assessed differences between groups. The meta-analysis found reduced total corpus callosum areas and reduced total cerebral and intracranial volumes in the patients with PTSD. The total hippocampus (left and right hippocampus) and gray matter volumes of the amygdala and frontal lobe were also reduced, but these differences were not significant. The functional studies revealed differences in brain region activation in response to stimuli in the post-traumatic stress symptoms/PTSD group. Our results confirmed that the pediatric patients with PTSD exhibited structural and functional brain abnormalities and that some of the abnormalities occurred in different brain regions than those observed in adults.

Single-nucleotide polymorphisms in genes related to the hypothalamic-pituitary-adrenal axis as risk factors for posttraumatic stress disorder.

Posttraumatic stress disorder (PTSD) is a common psychiatric disorder. The etiology of PTSD is multifactorial, depending on many environmental and genetic risk factors, and the exposure to life or physical integrity-threatening events. Several studies have shown significant correlations of many neurobiological findings with PTSD. Hypothalamic-pituitary-adrenal (HPA) axis dysfunction is strongly correlated with this disorder. One hypothesis is that HPA axis dysfunction may precede the traumatic event, suggesting that genes expressed in the HPA axis may be involved in the development of PTSD. This article reviews molecular genetic studies related to PTSD collected through a literature search performed in PubMed, MEDLINE, ScienceDirect, and Scientific Electronic Library Online (SciELO). The results of these studies suggest that several polymorphisms in the HPA axis genes, including FKBP5, NR3C1, CRHR1, and CRHR2, may be risk factors for PTSD development or may be associated with the severity of PTSD symptoms.

Children working on the streets in Brazil: predictors of mental health problems.

The objective of this study was to determine which factors predict higher risk for mental health problems in children working on the streets. We studied a sample of families that had at least one child working on the streets, from October 2008 to March 2009. The instruments applied were the parent version strengths and difficulties questionnaire (SDQ), the childhood trauma questionnaire (CTQ) for children and caregivers, the WorldSAFE core questionnaire, the global assessment of relational functioning scale (GARF), the schedule for affective disorders and schizophrenia for school-age children (K-SADS), and a socio-demographic questionnaire. 191 children between 7 and 14 years of age were analyzed; 126 (66%) were working on the streets, and 65 were siblings who did not work on the streets. Multivariate analysis showed that mental health problems in the caregivers, violent behaviors of the caregivers toward the children, absence of a partner living in the house, and lower levels of family functioning increased the risk of mental health problems in the children. Caregivers reported severe forms of physical punishment against their children in 62% of cases. Caregivers who had suffered sexual abuse and emotional negligence in childhood were more violent with their children. Factors that increased risk for mental health symptoms in these children were caregivers' psychopathology, physical punishment at home, single-parent structure, and poor family functioning. Work on the streets did not influence the children's mental health, when multiple risk factors were considered; family characteristics were the most significant in this sample.

Peri-Traumatic Dissociation and Tonic Immobility as Severity Predictors of Posttraumatic Stress Disorder After Rape.

Some individuals show abnormal reactions to extreme fear and life-threatening situations, including tonic immobility (TI) and peri-traumatic dissociation (PTD). We aimed to investigate the association of TI and PTD with posttraumatic stress disorder (PTSD) in women who experienced sexual violence and the risk factors for PTD occurrence. We compared PTSD severity in 86 young adult women with PTSD after a sexual violence exposure grouped according to the presence of PTD and TI. In addition, we investigated whether PTD is associated with depression and anxiety symptoms and assessed potential risk factors for PTD reaction. We found a significant positive correlation between PTSD severity and PTD occurrence (R2 = .132; p = .001). PTD was also positively correlated with all clusters of PTSD symptoms except the Clinician-Administered PTSD Scale avoidance cluster (p = .058). PTD was strongly correlated with anxiety (R2 = .619; p < .001) and depressive symptoms (R2 = .547; p < .001). Multiple logistic regression showed that history of physical abuse (odds ratio [OR]: 1.386; p = .011) and sexual abuse (OR: 1.947; p = .004) during childhood were associated with PTD occurrence. Other risk factors for PTD were having less years of study (OR: 0.216; p = .016) and lower income (OR: 7.403; p = .028). TI measures were available for a subsample of 29 women. We found no association between TI and PTSD severity. PTD, but not TI, is significantly associated with more severe PTSD, depressive, and anxiety symptoms. Less-educated women with a history of childhood abuse and a lower income are at risk of PTD occurrence during a sexual violence episode.

Interpersonal psychotherapy versus sertraline for women with posttraumatic stress disorder following recent sexual assault: a randomized clinical trial.

Background: Sexual assault often triggers posttraumatic stress disorder (PTSD), a potentially chronic severe mental disorder. Most guidelines recommend selective serotonin reuptake inhibitors (SSRIs) and trauma-focused psychotherapies as treatment options. Interpersonal Psychotherapy (IPT), adapted for PTSD (IPT-PTSD), focuses on interpersonal consequences of trauma rather than confronting the trauma itself. Studies have found IPT-PTSD efficaciously reduced PTSD symptoms with limited attrition. No efficacy trials have compared IPT-PTSD and SSRI. We hypothesized IPT would reduce PTSD, anxiety, and depressive symptoms more than sertraline among women with PTSD following a recent sexual assault. Objectives: To compare the efficacy of IPT-PTSD to SSRI sertraline in a 14-week randomized clinical trial for women with PTSD following a recent sexual assault. Methods: Seventy-four women with PTSD who had suffered sexual assault in the last six months were randomly assigned to 14 weeks of IPT-PTSD (n = 39) or sertraline (n = 35). Instruments assessed PTSD, anxiety, and depressive symptoms. This randomized clinical trial was conducted in São Paulo, Brazil, using the Clinician-Administered PTSD Scale-5 (CAPS-5) as the primary outcome measure. Results: Both treatments significantly reduced PTSD, anxiety, and depressive symptoms, without between-group outcome differences. CAPS-5 mean decreased from 42.5 (SD = 9.4) to 27.1 (SD = 15.9) with sertraline and from 42.6 (SD = 9.1) to 29.1 (SD = 15.5) with IPT-PTSD. Attrition was high in both arms (p = .40). Conclusions: This trial showed within-group improvements without differences between IPT-PTSD and sertraline treatment of PTSD. Our findings suggest that non-exposure-based psychotherapies may benefit patients with PTSD, although we did not directly compare these treatments to an exposure therapy.

Antecedentes: La agresión sexual con frecuencia gatilla un trastorno de estrés postraumático (TEPT), un trastorno mental severo potencialmente crónico. La mayoría de las guías clínicas recomiendan los inhibidores selectivos de la receptación de serotonina (ISRSs) y psicoterapias focalizadas en trauma como opciones de tratamiento. La Psicoterapia Interpersonal (PIP), adaptada para TEPT (PIP-TEPT), se focaliza en las consecuencias interpersonales del trauma en lugar de confrontar el trauma en sí. Los estudios han encontrado que la PIP-TEPT eficazmente redujo los síntomas de TEPT con una deserción limitada. Ningún ensayo de eficacia ha comparado PIP-TEPT e ISRS. Hipotetizamos que la PIP-TEPT puede reducir los síntomas de TEPT, ansiedad y depresión más que la sertralina entre las mujeres con TEPT después de una agresión sexual reciente.Objetivos: Comparar la eficacia de la PIP-TEPT con sertralina, un ISRS en un ensayo clínico aleatorizado de 14 semanas para mujeres con TEPT después de una agresión sexual reciente.Métodos: Setenta y cuatro mujeres con TEPT que habían sufrido de una agresión sexual en los últimos seis meses fueron asignadas aleatoriamente a 14 semanas de PIP-TEPT (n = 39) o sertralina (n = 35). Los instrumentos evaluaron síntomas de TEPT, ansiedad y depresión. Este ensayo clínico aleatorizado se realizó en San Pablo, Brasil, utilizando la Escala de TEPT administrada por el clínico (CAPS-5, por sus siglas en inglés) como medida de resultado primaria.Resultados: Ambos tratamientos redujeron significativamente los síntomas de TEPT, ansiedad y depresión, sin diferencias de resultados entre los grupos. La media del CAPS-5 se redujo de 42.5 (DE = 9.4) a 27.1 (DE = 15.9) con sertralina y de 42.6 (DE = 9.1) a 29.1 (DE = 15.5) con la PIP-TEPT. La deserción fue alta en ambos tratamientos (p = .40).Conclusiones: Este ensayo mostro mejoría entre grupos sin diferencias entre la PIP-TEPT y sertralina en el tratamiento del TEPT. Nuestros hallazgos sugieren que las psicoterapias no basadas en la exposición pueden beneficiar a los pacientes con TEPT, aunque no comparamos directamente estos tratamientos con una terapia de exposición.Registro Brasileño de Ensayos Clínicos RBR-3z474z.

Increased immuno-inflammatory mediators in women with post-traumatic stress disorder after sexual assault: 1-Year follow-up.

BACKGROUND: Sexual violence is a traumatic event that can trigger post-traumatic stress disorder (PTSD) and generate biological responses to stress characterized by inhibiting the hypothalamic-pituitary axis (HPA), altering immune activity, and changing the structure and function of the brain. PTSD is associated with increased levels of inflammatory markers. This study aimed to measure differences in inflammatory markers and HPA hormone levels between women with PTSD due to sexual violence and controls at baseline and after 1-year follow-up. METHODS: Fifty-eight women with PTSD resulting from sexual assault occurring up to 6 months prior were compared to 41 female controls. The patients were followed for 1 year. At baseline (T1), we measured inflammatory biomarkers. We also applied the Mini International Neuropsychiatric Interview (MINI), the Clinician-Administered Post-Traumatic Stress Disorder Scale-5, the Beck Depression Inventory, the Beck Anxiety Inventory, and the Childhood Trauma Questionnaire. The patients were randomized to receive treatment with sertraline or interpersonal psychotherapy for 14 weeks (T2) and then continued the usual treatment if deemed necessary for 1 year. The same interviews and examinations were repeated after 1 year (T3). RESULTS: At baseline, the patients had significantly higher adrenocorticotropic hormone levels, compared to controls; however, there was no baseline difference in inflammatory markers or cortisol. After 1 year, there were significantly higher levels of interleukin-1ß (p < 0.0001), monocyte chemoattractant protein-1 (p < 0.0001), tumor necrosis factor-α (p < 0.0001), c-reactive protein (p < 0.0001), and cortisol (p = 0.046) in the patient group. In addition to PTSD, 56 patients presented with a major depressive episode at T1 (according to the MINI). At the end of 1 year, there was a significant improvement in depressive (p < 0.001), anxiety (p = 0.03), and PTSD symptoms (p < 0.001) regardless of the treatment received. DISCUSSION: The increase of the inflammatory markers after 1 year, even with symptomatic improvement, may indicate that PTSD following sexual violence is associated with high depressive symptoms. This association may have a different pattern of immunoendocrine alterations than PTSD only. Furthermore, these alterations may persist in the long term, even with the improvement of the symptoms, probably generating an immunological imprint that can lead to future clinical consequences. This study adds to the current knowledge of PTSD neurobiology and contributes to broadening approaches to this disorder.

The positive impact of maternal depression intervention on children's emotional and behavioral symptoms in a low-resource setting.

OBJECTIVE: Children of depressed mothers are at risk of developing mental health problems. We sought to determine whether treatment for maternal depression delivered by community health workers (CHW) would decrease behavioral/emotional symptoms in their child. An intervention treating maternal depressive symptoms in a low-middle-income country can have a high global impact. METHODS: CHW were trained to deliver a psychosocial intervention for mothers with depression in a primary care setting. 49 mothers and 60 children were assessed pre-intervention, post-intervention, and at a 6-months follow-up. Child behavioral/emotional symptoms were evaluated by type of change in maternal depressive symptoms: remission and response. RESULTS: An overall decrease in maternal depressive symptoms from baseline to post-intervention and 6-month follow-up were found. Remission and response of maternal depression was associated with better outcomes related to child´s behavioral/emotional symptoms at the 6-month follow-up (p = 0.0247, Cohen's d: 0.76; p = 0.0224, Cohen's f: 0.44) but not at post-intervention (p = 0.1636, Cohen's d: 0.48; p = 0.0720, Cohen's f: 0.33). CONCLUSION: Maternal depression improvement was related to their child's decreased behavioral/emotional symptoms. Our results suggest that interventions addressing maternal depression in primary care is a viable strategy to prevent behavioral/emotional symptoms in the next generation.

Social and Psychiatric Factors of Suicidal Thoughts and Behaviors in Mozambican Adolescents.

Globally, suicide is the second leading cause of death for youth ages 10-24 years, and more than 75% of all deaths by suicide occur in low- and middle-income countries (LMIC).1 Suicidal thoughts (ST) and suicidal behaviors (SB), valuable signals for early detection and prevention of suicide deaths, have been associated with a number of different factors in adolescents, including gender and age, socioeconomic status, exposure to childhood adversity, and psychopathology.2 However, research has largely focused on Western, White populations from high-income countries (HIC).2 To lessen the suicide burden among adolescents in LMIC, there is an urgent need to identify contextually relevant risk identification and treatment targets. In Mozambique, the country with the highest suicide rate in southern Africa, this need is particularly dire, as there are fewer than 2 mental health specialists per 100,000 inhabitants,3 and limited resources must be efficiently targeted in youth suicide prevention efforts. We conducted a cross-sectional study at 2 secondary schools in the Mozambican capital Maputo City to identify the social and psychiatric factors associated with ST and SB in Mozambican adolescents.

Lay HIV counselors' knowledge and attitudes toward depression: A mixed-methods cross-sectional study at primary healthcare centers in Mozambique.

Introduction: Depression is the most common mental disorder among people living with HIV/AIDS and has a negative impact on HIV treatment outcomes. Training lay HIV counselors to identify and manage depression may contribute to improved patient access and adherence to treatment, and reduce stigma and discrimination among lay health workers toward both HIV and depression. The purpose of this study was to assess the current knowledge and attitudes of lay HIV counselors toward managing depression in primary care in Mozambique. Methods: We conducted a mixed-methods cross-sectional study to assess depression-related knowledge and attitudes among lay HIV counselors in 13 primary healthcare facilities in Mozambique. We used the quantitative Depression Attitude Questionnaire (DAQ) scale, followed by open-ended questions to further explore three key DAQ domains: the nature of depression, treatment preferences, and professional attitudes or reactions. Results: The sample included 107 participants (77.6% female, mean age: 32.3 years, sd = 7.4). Most (82.2%) had less than a high/technical school education. Findings suggested that some HIV counselors had knowledge of depression and described it as a cluster of psychological symptoms (e.g., deep sadness, anguish, apathy, isolation, and low self-esteem) sometimes leading to suicidal thoughts, or as a consequence of life stressors such as loss of a loved one, abuse, unemployment or physical illness, including being diagnosed with HIV infection. HIV counselors identified talking to trusted people about their problems, including family and/or counseling with a psychotherapist, as the best way for patients to deal with depression. While acknowledging challenges, counselors found working with patients with depression to be rewarding. Conclusion: Lay health counselors identified HIV and psychosocial issues as key risk factors for depression. They believed that the treatment approach should focus on social support and psychotherapy.

Association of Task-Shared Psychological Interventions With Depression Outcomes in Low- and Middle-Income Countries: A Systematic Review and Individual Patient Data Meta-analysis.

Importance: Task sharing, the training of nonspecialist workers with no formal experience in counseling, is a promising strategy for addressing the large gap in treatment for depression in low- and middle-income countries (LMICs). Objective: To examine the outcomes and moderators of task-shared psychological interventions associated with depression severity, response, and remission. Data Sources: Systematic literature searches in PubMed, Embase, PsycINFO, and Cochrane Library up to January 1, 2021. Study Selection: Randomized clinical trials (RCTs) of task-shared psychological interventions compared with control conditions for adults with depressive symptoms in LMICs were included. Data Extraction and Synthesis: Two researchers independently reviewed the titles, abstracts, and full text of articles from an existing generic meta-analytic database that includes all RCTs on psychotherapy for depression. A systematic review and individual patient data (IPD) meta-analysis was used to estimate the outcomes of task-shared psychological interventions across patient characteristics using mixed-effects models. Procedures for abstracting data and assessing data quality and validity followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline. Main Outcomes and Measures: Primary outcome was reduction in depression symptom severity measured by the 9-item Patient Health Questionnaire (PHQ-9). Response and remission rates were also estimated. Results: Of 13 eligible trials, 11 (4145 participants) contributed IPD. Task-shared psychological interventions were associated with a greater decrease in depressive symptom severity than control conditions (Hedges g, 0.32; 95% CI, -0.26 to -0.38). Participants in the intervention groups had a higher chance of responding (odds ratio, 2.11; 95% CI, 1.60 to 2.80) and remitting (odds ratio, 1.87; 95% CI, 1.20 to 1.99). The presence of psychomotor symptoms was significantly associated with the outcomes of task-shared psychological interventions (ß [SE], -1.21 [0.39]; P = .002). No other significant associations were identified. Heterogeneity among the trials with IPD was 74% (95% CI, 53%-86%). Conclusions and Relevance: In this meta-analysis of IPD, task-shared psychological interventions were associated with a larger reduction in depressive symptom severity and a greater chance of response and remission than control conditions. These findings show potential for the use of task-sharing of psychological interventions across different groups of patients with depression. Further research would help identify which people are most likely to benefit and strengthen larger-scale implementation of this strategy to address the burden of depression in LMICs.

Technology and implementation science to forge the future of evidence-based psychotherapies: the PRIDE scale-up study.

OBJECTIVE: To report the interim results from the training of providers inevidence-based psychotherapies (EBPs) and use of mobile applications. DESIGN AND SETTING: The Partnerships in Research to Implement and Disseminate Sustainable and Scalable Evidence (PRIDE) study is a cluster-randomised hybrid effectiveness-implementation trial comparing three delivery pathways for integrating comprehensive mental healthcare into primary care in Mozambique. Innovations include the use of EBPs and scaling-up of task-shifted mental health services using mobile applications. MAIN OUTCOME MEASURES: We examined EBP training attendance, certification, knowledge and intentions to deliver each component. We collected qualitative data through rapid ethnography and focus groups. We tracked the use of the mobile applications to investigate early reach of a valid screening tool (Electronic Mental Wellness Tool) and the roll out of the EBPs PARTICIPANTS: Psychiatric technicians and primary care providers trained in the EBPs. RESULTS: PRIDE has trained 110 EBP providers, supervisors and trainers and will train 279 community health workers in upcoming months. The trainings improved knowledge about the EBPs and trainees indicated strong intentions to deliver the EBP core components. Trained providers began using the mobile applications and appear to identify cases and provide appropriate treatment. CONCLUSIONS: The future of EBPs requires implementation within existing systems of care with fidelity to their core evidence-based components. To sustainably address the vast mental health treatment gap globally, EBP implementation demands: expanding the mental health workforce by training existing human resources; sequential use of EBPs to comprehensively treat mental disorders and their comorbid presentations and leveraging digital screening and treatment applications.

Efficacy of interpersonal therapy-group format adapted to post-traumatic stress disorder: an open-label add-on trial.

BACKGROUND: Post-traumatic stress disorder (PTSD) is a highly prevalent condition, yet available treatments demonstrate only modest efficacy. Exposure therapies, considered by many to be the "gold-standard" therapy for PTSD, are poorly tolerated by many patients and show high attrition. We evaluated interpersonal therapy, in a group format, adapted to PTSD (IPT-G PTSD), as an adjunctive treatment for patients who failed to respond to conventional psychopharmacological treatment. METHODS: Research participants included 40 patients who sought treatment through a program on violence in the department of psychiatry of Federal University of São Paulo (UNIFESP). They had received conventional psychopharmacological treatment for at least 12 weeks and failed to have an adequate clinical response. After signing an informed consent, approved earlier by the UNIFESP Ethics Review Board, they received a semi-structured diagnostic interview (SCID-I), administered by a trained mental health worker, to confirm the presence of a PTSD diagnosis according to DSM-IV criteria. Other instruments were administered, and patients completed out self-report instruments at baseline, and endpoint to evaluate clinical outcomes. RESULTS: Thirty-three patients completed the trial, but all had at least one second outcome evaluation. There were significant improvements on all measures, with large effect sizes. CONCLUSIONS: IPT-G PTSD was effective not only in decreasing symptoms of PTSD, but also in decreasing symptoms of anxiety and depression. It led to significant improvements in social adjustment and quality of life. It was well tolerated and there were few dropouts. Our results are very preliminary; they need further confirmation through randomized controlled clinical trials.

Violence and post-traumatic stress disorder in Sao Paulo and Rio de Janeiro, Brazil: the protocol for an epidemiological and genetic survey.

BACKGROUND: violence is a public health major concern, and it is associated with post-traumatic stress disorder and other psychiatric outcomes. Brazil is one of the most violent countries in the world, and has an extreme social inequality. Research on the association between violence and mental health may support public health policy and thus reduce the burden of disease attributable to violence. The main objectives of this project were: to study the association between violence and mental disorders in the Brazilian population; to estimate the prevalence rates of exposure to violence, post-traumatic stress disorder, common metal disorder, and alcohol hazardous use and dependence: and to identify contextual and individual factors, including genetic factors, associated with the outcomes. METHODS/DESIGN: one phase cross-sectional survey carried out in Sao Paulo and Rio de Janeiro, Brazil. A multistage probability to size sampling scheme was performed in order to select the participants (3000 and 1500 respectively). The cities were stratified according to homicide rates, and in Sao Paulo the three most violent strata were oversampled. The measurements included exposure to traumatic events, psychiatric diagnoses (CIDI 2.1), contextual (homicide rates and social indicators), and individual factors, such as demographics, social capital, resilience, help seeking behaviours. The interviews were carried between June/2007 February/2008, by a team of lay interviewers. The statistical analyses will be weight-adjusted in order to take account of the design effects. Standardization will be used in order to compare the results between the two centres. Whole genome association analysis will be performed on the 1 million SNP (single nucleotide polymorphism) arrays, and additional association analysis will be performed on additional phenotypes. The Ethical Committee of the Federal University of Sao Paulo approved the study, and participants who matched diagnostic criteria have been offered a referral to outpatient clinics at the Federal University of Sao Paulo and Federal University of Rio de Janeiro.

The posttraumatic stress disorder project in Brazil: neuropsychological, structural and molecular neuroimaging studies in victims of urban violence.

BACKGROUND: Life trauma is highly prevalent in the general population and posttraumatic stress disorder is among the most prevalent psychiatric consequences of trauma exposure. Brazil has a unique environment to conduct translational research about psychological trauma and posttraumatic stress disorder, since urban violence became a Brazilian phenomenon, being particularly related to the rapid population growth of its cities. This research involves three case-control studies: a neuropsychological, a structural neuroimaging and a molecular neuroimaging study, each focusing on different objectives but providing complementary information. First, it aims to examine cognitive functioning of PTSD subjects and its relationships with symptomatology. The second objective is to evaluate neurostructural integrity of orbitofrontal cortex and hippocampus in PTSD subjects. The third aim is to evaluate if patients with PTSD have decreased dopamine transporter density in the basal ganglia as compared to resilient controls subjects. This paper shows the research rationale and design for these three case-control studies. METHODS AND DESIGN: Cases and controls will be identified through an epidemiologic survey conducted in the city of São Paulo. Subjects exposed to traumatic life experiences resulting in posttraumatic stress disorder (cases) will be compared to resilient victims of traumatic life experiences without PTSD (controls) aiming to identify biological variables that might protect or predispose to PTSD. In the neuropsychological case-control study, 100 patients with PTSD, will be compared with 100 victims of trauma without posttraumatic stress disorder, age- and sex-matched controls. Similarly, 50 cases and 50 controls will be enrolled for the structural study and 25 cases and 25 controls in the functional neuroimaging study. All individuals from the three studies will complete psychometrics and a structured clinical interview (the Structured Clinical Interview for DSM-IV and the Clinician-Administered PTSD Scale, Beck Anxiety Inventory, Beck Depression Inventory, Global Assessment of Function, The Social Adjustment Scale, Medical Outcomes Study 36-Item Short-Form Health Survey, Early Trauma Inventory, Clinical global Impressions, and Peritraumatic Dissociative Experiences Questionnaire). A broad neuropsychological battery will be administered for all participants of the neuropsychological study. Magnetic resonance scans will be performed to acquire structural neuroimaging data. Single photon emission computerized tomography with [(99m)Tc]-TRODAT-1 brain scans will be performed to evaluate dopamine transporters. DISCUSSION: This study protocol will be informative for researchers and clinicians interested in considering, designing and/or conducting translational research in the field of trauma and posttraumatic stress disorder.

[Childhood maltreatment and adult psychopathology: pathways to hypothalamic-pituitary-adrenal axis dysfunction]. / Maus-tratos na infância e psicopatologia no adulto: caminhos para a disfunção do eixo hipotálamo-pituitária-adrenal.

OBJECTIVE: The aim of this paper was to examine the relationship between childhood maltreatment and adult psychopathology, as reflected in hypothalamic-pituitary-adrenal axis dysfunction. METHOD: A selective review of the relevant literature was undertaken in order to identify key and illustrative research findings. RESULTS: There is now a substantial body of preclinical and clinical evidence derived from a variety of experimental paradigms showing how early-life stress is related to hypothalamic-pituitary-adrenal axis function and psychological state in adulthood, and how that relationship can be modulated by other factors. DISCUSSION: The risk for adult psychopathology and hypothalamic-pituitary-adrenal axis dysfunction is related to a complex interaction among multiple experiential factors, as well as to susceptibility genes that interact with those factors. Although acute hypothalamic-pituitary-adrenal axis responses to stress are generally adaptive, excessive responses can lead to deleterious effects. Early-life stress alters hypothalamic-pituitary-adrenal axis function and behavior, but the pattern of hypothalamic-pituitary-adrenal dysfunction and psychological outcome in adulthood reflect both the characteristics of the stressor and other modifying factors. CONCLUSION: Research to date has identified multiple determinants of the hypothalamic-pituitary-adrenal axis dysfunction seen in adults with a history of childhood maltreatment or other early-life stress. Further work is needed to establish whether hypothalamic-pituitary-adrenal axis abnormalities in this context can be used to develop risk endophenotypes for psychiatric and physical illnesses.

Revictimization as a high-risk factor for development of posttraumatic stress disorder: a systematic review of the literature.

OBJECTIVE: Much research has been published on the role of sexual revictimization in the emergence of mental disorders in adulthood, but findings have sometimes been contradictory. The present systematic review sought to assess the state of the evidence on revictimization as a potential factor for the emergence of posttraumatic stress disorder (PTSD). METHODS: Electronic searches were conducted in five databases (MEDLINE/PubMed, Cochrane Library, Campbell Library, PsycINFO, and LILACS), using the terms PTSD, posttraumatic stress disorder, child abuse, and rape. RESULTS: We identified nine articles that established a connection among childhood sexual abuse (CSA), sexual revictimization in adulthood, and development of PTSD. Eight of the nine papers included were classified as having strong methodological quality (grade VI). One was classified as IV, with an average quality-of-evidence rating. The mean methodological quality score of the articles was 5.5, and the quality of evidence was deemed strong. CONCLUSION: In the included studies, PTSD symptoms were most prevalent in the CSA + adult sexual assault groups, providing further evidence for the revictimization hypothesis.

Use of mental health services by community-resident adults with DSM-IV anxiety and mood disorders in a violence-prone area: São Paulo, Brazil.

BACKGROUND: While under-use of mental health services by adults with anxiety and/or depression is well established, use in a violence-prone area, and as a function of diagnosis and personality characteristics such resilience, is little known. We examine the sociodemographic and personality characteristics (specifically resilience), associated with use of mental health services in a violence-prone city by those with anxiety, depression, and their comorbidity. METHODS: The structured Composite International Diagnostic Interview was used to identify 12-month DSM-IV- and ICD-10-defined anxiety and depression in a cross-sectional, representative, community-resident sample age 15-75y (N = 2536) in São Paulo, Brazil, and their use of mental health services. Resilience was determined by the Wagnild and Young scale. Analyses, using weighted, design-corrected statistical tests, included frequency measures and multivariable logistic regression. RESULTS: Mental health services were used by 10% with only anxiety, 22% with only depression, and 34% with comorbidity, with odds of use in controlled analyses doubling from anxiety to depression to comorbidity. Use was significantly higher among those who were white, older (age >30 years, with substantial social support, low resilience, living in low homicide rate areas; use was not affected by experience of traumatic events. Psychiatrists, general practitioners, and psychologists were the primary providers. LIMITATIONS: Cross-sectional design CONCLUSIONS: Contrary to expectation, use was greater among residents of lower homicide areas, and was not associated with personal traumatic experience. This may reflect increased immunity to violence in higher homicidal rate areas, lower resilience, and poorer access to services. Increased access to mental health services is needed.
