RESUMO

Incidence of mental health disorders are rising in modernity, with psychological stress linked to a propensity for developing various chronic diseases due to a relative inability of the body to counter the allostatic load on cellular level. Despite these high rates of comorbidities associated with posttraumatic stress disorder (PTSD), there is still a lack of understanding in terms of the peripheral effects of PTSD on tissue level. Therefore, the purpose of this study was to profile basal dermal fibroblast functional status in PTSD using a wide range of markers involved in the cell-to-cell communication facilitated by fibroblasts. Primary dermal fibroblasts derived from patients diagnosed with PTSD (n = 11) and matched trauma exposed controls (i.e. who did not develop PTSD, n = 10) were cultured using standard techniques. The patients and controls were matched based on age, sex, body-mass index (BMI) and lifestyle. The growth rate, population doubling time, cell surface marker expression (CD31, FNDC5) (flow cytometry), secretome (TIMP-2, MMP-9) (ELISAs), intracellular signalling capacity (Fluo-4 Ca2+ flux) and gene expression (IL-6, IL-10, PTX-3, iNOS, Arg1) were compared between groups. The data illustrated significant PTSD-associated fibroblast conditioning resulting in a blunted signalling capacity. This observation highlights the importance of including tissue-specific investigations in future studies focused on elucidating the association between PTSD and subsequent risk for somatic disease.

RESUMO

BACKGROUND: Romantic relationship dissolutions (RRDs) are associated with posttraumatic stress symptoms (PTSS). Functional magnetic resonance imaging in RRD studies indicate overlapping neural activation similar to posttraumatic stress disorder. These studies combine real and hypothetical rejection, and lack contextual information and control and/or comparison groups exposed to non-RRD or DSM-5 defined traumatic events. AIM: We investigated blood oxygen level dependent (BOLD) activation in the hippocampus, amygdala, and insula of participants with RRDs compared with other traumatic or non-trauma stressors. METHODS: Emerging adults (mean age = 21.54 years; female = 74.7 %) who experienced an RRD (n = 36), DSM-5 defined trauma (physical and/or sexual assault: n = 15), or a non-RRD or DSM-5 stressor (n = 28) completed PTSS, depression, childhood trauma, lifetime trauma exposure, and attachment measures. We used a general and customised version of the International Affective Picture System to investigate responses to index-trauma-related stimuli. We used mixed linear models to assess between-group differences, and ANOVAs and Spearman's correlations to analyse factors associated with BOLD activation. RESULTS: BOLD activity increased between index-trauma stimuli as compared to neutral stimuli in the hippocampus and amygdala, with no significant difference between the DSM-5 Trauma and RRD groups. Childhood adversity, sexual orientation, and attachment style were associated with BOLD activation changes. Breakup characteristics (e.g., initiator status) were associated with increased BOLD activation in the hippocampus and amygdala, in the RRD group. CONCLUSION: RRDs should be considered as potentially traumatic events. Breakup characteristics are risk factors for experiencing RRDs as traumatic. LIMITATION: Future studies should consider more diverse representation across sex, ethnicity, and sexual orientation.

RESUMO

Background: Survivors of sexual violence are at higher risk of adverse mental health outcomes compared to those exposed to other interpersonal traumas.Objective: To examine the trajectory of both post-traumatic stress disorder (PTSD) and depression as well as the role of early counselling over 24 months among rape survivors.Method: The South African Rape Impact Cohort Evaluation (RICE) study enrolled women aged 16-40 years attending post-rape care services within 20 days of a rape incident (n = 734), and a comparison group (n = 786) was recruited from primary health care. Women were followed for 24 months; the main study outcomes were depression and PTSD. Reports of early supportive counselling by the exposed group were also included. The analysis included an adjusted joint mixed model with linear splines to account for correlated observations between the outcomes.Results: At 24 months, 45.2% of the rape-exposed women met the cut-off for depression and 32.7% for PTSD. This was significantly higher than levels found among the unexposed. Although a decline in depression and PTSD was seen at 3 months among the women who reported a rape, mean scores remained stable thereafter. At 24 months mean depression scores remained above the depression cut-off (17.1) while mean PTSD scores declined below the PTSD cut-off (14.5). Early counselling was not associated with the trajectory of either depression or PTSD scores over the two years in rape-exposed women with both depression and PTSD persisting regardless of early counselling.Conclusion: The study findings highlight the importance to find and provide effective mental health interventions post-rape in South Africa.

RESUMO

Background: Timely and effective interventions can alleviate or prevent the development of clinical symptomatology in trauma-exposed individuals. However, due to limited access to these interventions, and/or stigma around accessing mental health services, there is an unmet need. Internet-and mobile-based interventions may help to address this need.Aims: This review aims to (i) synthesise the evidence on feasibility, acceptability, and effectiveness of the 'PTSD Coach' intervention (both web-based and mobile applications) in trauma-exposed individuals; (ii) evaluate the quality of this research; and (iii) identify challenges and recommendations related to 'PTSD Coach' intervention delivery.Method: Systematic database searches were conducted (PubMed/MEDLINE, PsycINFO, EMBASE, PLoS, Web of Science, PTSDpubs, Scopus, and clinical trial databases). Review inclusion was based on predefined inclusion criteria, and study quality was assessed with the mixed methods appraisal and the risk-of-bias tools for randomised trials. Where feasible, meta-analytical pooling of intervention effects on posttraumatic stress symptoms (PTSS) was conducted.Results: Seventeen manuscripts reporting on 16 primary studies were included with the majority evaluating a self-managed PTSD Coach mobile application intervention. Most studies were conducted in higher-income countries and females were over-represented. For both platforms, satisfaction and perceived helpfulness were generally high but type of smart device operating system was identified as an influence. The pooled effect size in symptom severity in the intervention group compared to the comparison group was not significant (standardised mean difference =  - 0.19) (95% CI - 0.41 to - 0.03, p = .09). Heterogeneity was not significant (p = .14; I2 = 40%). No study was excluded based on quality assessment.Conclusion: Findings support the feasibility and acceptability of 'PTSD Coach' in trauma-exposed individuals. However, evidence on the effectiveness on PTSS remains limited. More research is still needed in low-middle-income countries, particularly those in which supported 'PTSD Coach' interventions are evaluated in larger and more diverse samples.


Most studies evaluated a self-managed PTSD Coach mobile application intervention in higher-income countries.Findings generally support the feasibility and acceptability of both PTSD Coach mobile application and PTSD Coach Online in trauma-exposed individuals but the evidence on the effectiveness on posttraumatic stress symptoms remains limited.More research is needed especially in low-middle-income countries where there is often limited access to the needed interventions.

RESUMO

Adverse pregnancy outcomes (APOs) are common occurrences that contribute to negative maternal and child health outcomes. Our aim was to test the hypothesis that trauma exposure and depression are drivers of the better-recognised risk factors for miscarriage, abortion and stillbirths. Our comparative cohort study based in Durban, South Africa recruited women who reported a recent rape (n = 852) and those who had never experienced rape (n = 853), with follow-up for 36 months. We explored APOs (miscarriage, abortion or stillbirth) among those having a pregnancy during follow-up (n = 453). Potential mediators were baseline depression, post-traumatic stress symptoms, substance abuse, HbA1C, BMI, hypertension and smoking. A structural equation model (SEM) was used to determine direct and indirect paths to APO. Overall, 26.6% of the women had a pregnancy in the follow-up period and 29.4% ended in an APO, with miscarriage (19.9%) the most common outcome, followed by abortion (6.6%) and stillbirths (2.9%). The SEM showed two direct pathways from exposure to childhood trauma, rape and other trauma, to APO which were ultimately mediated by hypertension and/or BMI, but all paths to BMI were mediated by depression and IPV-mediated pathways from childhood and other trauma to hypertension. Food insecurity mediated a pathway from experiences of trauma in childhood to depression. Our study confirms the important role of trauma exposure, including rape, and depression on APOs, through their impact on hypertension and BMI. It is critical that violence against women and mental health are more systematically addressed in antenatal, pregnancy and postnatal care.

RESUMO

A better understanding of protective factors against childhood depression may allow for the mitigation of severe and chronic symptoms and the timely implementation of intervention strategies. This study investigated the protective effect of having a secure base script on depressive symptoms when children face daily stressors. To test this hypothesis, moderation analyses were performed in a cross-sectional study with 378 children (48.5% boys, 51.5%) aged 8-12 years (M = 10.20; SD = 0.57). The results provided some support for the moderation effect when secure base script knowledge was investigated as a categorical variable in middle childhood. However, the results did not support the moderation effect when investigating secure base script as a continuous variable. Therefore, future investigations may need to address whether a categorical approach could better elucidate the protective role of secure base script knowledge in childhood depression.

RESUMO

Sleep disturbances and suicidality are common presentations of mood and anxiety disorders. If not closely monitored post-discharge, patients may be at an increased risk of symptom worsening and completed suicide. We explored the associations between telephone mood monitoring, suicidality, and sleep quality in a clinical sample. Fifty inpatients (mean age = 39.49, SD = 11.17; female = 74%) with a mood and/or anxiety disorder were telephonically monitored weekly post-discharge for16 weeks for depression and mania. Suicidality and sleep quality were assessed at intake (pre-discharge), and at weeks 4, 8, 12, and 16 post-discharge. ANOVA indicated that suicidality significantly decreased, and sleep quality improved over 16 weeks. Linear regression analysis indicated that depression severity at week 1 post-discharge significantly predicted suicidality and sleep quality at week 16. Mania severity at week 1 post-discharge predicted sleep quality, but not suicidality, at week 16. Participants generally had positive experiences of the monitoring and perceived it as helpful. Monitoring of mood state, suicidality, and sleep quality post-discharge may allow for early detection of relapse when initiated at 1-week post-discharge. This is a potentially cost-effective intervention and may relieve the burden on the mental healthcare system, especially when face-to-face consultations are not possible.

RESUMO

Structural brain differences have been described in first-episode schizophrenia spectrum disorders (FES), and often overlap with those evident in the metabolic syndrome (MetS). We examined the associations between body mass index (BMI) and brain structures involved in food intake regulation in minimally treated FES patients (n = 117) compared to healthy controls (n = 117). The effects of FES diagnosis, BMI and their interactions on our selected prefrontal cortical thickness and subcortical gray matter volume regions of interest (ROIs) were investigated with hierarchical multivariate regressions, followed by post-hoc regressions for the individual ROIs. In a secondary analysis, we examined the relationships of other MetS risk factors and psychopathology with the brain ROIs. Both illness and BMI significantly predicted the grouped prefrontal cortical thickness ROIs, whereas only BMI predicted the grouped subcortical volume ROIs. For the individual ROIs, schizophrenia diagnosis predicted thinner left and right frontal pole and right lateral OFC thickness, and increased BMI predicted thinner left and right caudal ACC thickness. There were no significant main or interaction effects for diagnosis and BMI on any of the individual subcortical volume ROIs. Secondary analyses suggest associations between several brain ROIs and individual MetS risk factors, but not with psychopathology. Our findings indicate differential, independent effects for FES diagnosis and BMI on brain structures. Limited evidence suggests that the BMI effects are more prominent in FES. Exploratory analyses suggest associations between other MetS risk factors and some brain ROIs.

RESUMO

The global devastation caused by the COVID-19 pandemic and its mental health impact is undeniable. The physical and psychological consequences are wide-ranging - affecting patients fighting the disease, frontline workers in the trenches with them, healthcare staff deployed in high-care settings, and families disconnected from their loved ones in their darkest hours. Within 6 weeks of the COVID-19 outbreak in South Africa, the Department of Psychiatry at Stellenbosch University established the TBH/SU COVID Resiliency Clinic to provide psychological support to frontline workers at Tygerberg Hospital. Identified barriers in healthcare workers accessing mental healthcare resulted in moving towards an on-site visibility to try to remove some of these barriers. This greater on-site presence enabled networking and building of relationships with frontline staff that over time highlighted other frontline needs, such as providing psychosocial and spiritual support to patients and their families. We share challenges, lessons learned and recommendations from two initiatives: the TBH/SU COVID-19 Resiliency Clinic, and an embedded COVID Care Team (CCT). We describe the establishment, roll-out and progress of the Clinic and the subsequent CCT.

RESUMO

There is widespread use of traditional medicine in treating common mental disorders in South Africa. We aimed to (i) explore the self-identification of traditional healers (THs; how they refer to themselves, e.g., as healer, spiritualist, sangoma, etc.); (ii) determine if different types of THs treat different conditions (physical/psychological) or use different modes of diagnosis and treatment; (iii) identify factors that influence the willingness of THs to refer patients to biomedical hospitals; and (iv) compare TH practices between two provinces. Participants included Xhosa-speaking THs (mean age = 54.10, SD = 13.57 years) from the Western (n = 50) and Eastern (n = 68) Cape provinces. Participants completed a questionnaire regarding self-identification, mode of diagnosis/treatment, relationship with biomedical hospitals, type of condition(s) treated, and a Patient Health Questionnaire. There were significant associations between the type of TH (as self-identified) and (i) mode of diagnosis, (ii) mode of treatment, and (iii) type of condition(s) treated. Spiritualists, male THs, and THs who had previously been hospitalised for a mental disorder were more likely to treat mental disorders. THs who had previously been hospitalised for mental disorders were more likely to report a willingness to refer patients to biomedical hospitals. Findings highlight the complex practices of Xhosa-speaking THs. Collaboration between THs and mental health care professionals could be facilitated by focusing on male THs, spiritualists, and THs who have previously been hospitalised for mental illness. Future research should provide clearer operational definitions of the type of TH included.

RESUMO

AIMS: Mental disorders are common in people living with HIV (PLWH) but often remain untreated. This study aimed to explore the treatment gap for mental disorders in adults followed-up in antiretroviral therapy (ART) programmes in South Africa and disparities between ART programmes regarding the provision of mental health services. METHODS: We conducted a cohort study using ART programme data and linked pharmacy and hospitalisation data to examine the 12-month prevalence of treatment for mental disorders and factors associated with the rate of treatment for mental disorders among adults, aged 15-49 years, followed-up from 1 January 2012 to 31 December 2017 at one private care, one public tertiary care and two pubic primary care ART programmes in South Africa. We calculated the treatment gap for mental disorders as the discrepancy between the 12-month prevalence of mental disorders in PLWH (aged 15-49 years) in South Africa (estimated based on data from the Global Burden of Disease study) and the 12-month prevalence of treatment for mental disorders in ART programmes. We calculated adjusted rate ratios (aRRs) for factors associated with the treatment rate of mental disorders using Poisson regression. RESULTS: In total, 182 285 ART patients were followed-up over 405 153 person-years. In 2017, the estimated treatment gap for mental disorders was 40.5% (95% confidence interval [CI] 19.5-52.9) for patients followed-up in private care, 96.5% (95% CI 95.0-97.5) for patients followed-up in public primary care and 65.0% (95% CI 36.5-85.1) for patients followed-up in public tertiary care ART programmes. Rates of treatment with antidepressants, anxiolytics and antipsychotics were 17 (aRR 0.06, 95% CI 0.06-0.07), 50 (aRR 0.02, 95% CI 0.01-0.03) and 2.6 (aRR 0.39, 95% CI 0.35-0.43) times lower in public primary care programmes than in the private sector programmes. CONCLUSIONS: There is a large treatment gap for mental disorders in PLWH in South Africa and substantial disparities in access to mental health services between patients receiving ART in the public vs the private sector. In the public sector and especially in public primary care, PLWH with common mental disorders remain mostly untreated.

RESUMO

Romantic attachment rejection (RAR) is a highly prevalent phenomenon among young adults. Rejection by a romantic attachment figure can be a painful and incapacitating experience with lasting negative mental health sequelae, yet the underlying neurobiology of RAR is not well characterized. We systematically reviewed functional neuroimaging studies of adult RAR. Four functional magnetic resonance imaging (fMRI) studies that measured participants' responses to real or imagined RAR and met inclusion criteria were evaluated. These included studies were published between 2004 and 2018. Brain activity in adult participants with an RAR appears to be influenced by the stimulus used to elicit a reaction as well as by attachment styles. Brain regions that show a significant change in activation following a rejection stimulus include cortical regions (cingulate, insular, orbitofrontal, and prefrontal), and subcortical regions (angular gyrus, hippocampus, striatum, tegmental area, and temporal pole) and correspond to (i) pain, distress, and memory retrieval; (ii) reward, romantic love, and dopaminergic circuits; and (iii) emotion regulation and behavioural adaptation. Further neuroimaging studies of adult RAR, as moderated by stimulus and attachment style, are needed to better understand the underlying neurobiology of RAR.

RESUMO

This article sets out to investigate alcohol and substance use (ASU) among adolescents living with HIV (ALWH) in the sub-Saharan African setting of Uganda. A cross-sectional analysis of the records of 479 adolescents (aged between 12and 17 years) attending the study, "Mental health among HIV infected CHildren and Adolescents in KAmpala and Masaka, Uganda (the CHAKA study)" was undertaken. ASU was assessed through both youth self-report and caregiver report using the Diagnostic and Statistical Manual of Mental Disorders-5 referenced instruments, the Youth Inventory-4R and the Child and Adolescent Symptom Inventory-5 (CASI-5). Rates and association with potential risk and outcome factors were investigated using logistic regression models. The rate of ASU was 29/484 (5.9%) with the most frequently reported ASU being alcohol 22/484 (4.3%) and marijuana 10/484 (2.1%). Functional impairment secondary to ASU was reported by 10/484 (2.1%) of the youth. ASU was significantly associated with urban residence, caregiver psychological distress and the psychiatric diagnosis of post-traumatic stress disorder. On associations with negative outcomes, ASU was significantly associated with only "ever had sex". Health care for ALWH in sub-Saharan Africa should include ASU prevention and management strategies.

RESUMO

BACKGROUND: HIV/AIDS and potentially traumatic events (PTEs) or stressful life events (SLEs) and/or PTSD are independently associated with neurocognitive impairment (NCI). Literature suggests that HIV and PTE/SLE exposure independently and consistently affect various domains of cognition including language ability, working memory and psychomotor speed. There are limited data on the interaction between HIV infection and PTEs and their combined effect on NCI. OBJECTIVE: In this systematic review, we synthesise evidence for the combined effect of HIV infection and PTEs and SLEs and/or post-traumatic stress disorder (PTSD) on NCI of people living with HIV/AIDS (PLWHA) from high-, middle- and low- income countries. METHOD: Our inclusion criteria were observational epidemiological studies (case-control, cohort and cross-sectional designs) that investigated the interaction of HIV infection, PTEs and SLEs and/or PTSD and specifically their combined effect on NCI in adults. We searched a number of electronic databases including Pubmed/Medline, PsycINFO, Scopus and Global Health using the search terms: cognition, HIV/AIDS, observational studies, trauma and permutations thereof. RESULTS: Fifteen studies were included in the review, of which the majority were conducted in high-income countries. Ten of the fifteen studies were conducted in the United States of America (USA) and five in South Africa. Seven of these focused on early life stress/childhood trauma. The remaining studies assessed adult-onset PTEs and SLEs only. Eight studies included women only. Overall, the studies suggest that PTE and SLE exposure and/or PTSD are a significant risk factor for NCI in adults living with HIV, with impairments in memory and executive functions being the most likely consequence of PTE and SLE exposure. CONCLUSION: These findings highlight the need for trauma screening and for the integration of trauma-focused interventions in HIV care to improve outcomes.


Antecedentes: El VIH/SIDA y los eventos potencialmente traumáticos (PTEs) o los eventos estresantes de la vida (SLEs) y/o TEPT se asocian independientemente con el deterioro neurocognitivo (NCI). La literatura sugiere que la exposición al VIH, PTE y SLE afecta de manera independiente y consistente varios dominios de la cognición, incluida la capacidad del lenguaje, la memoria de trabajo y la velocidad psicomotora. Hay datos limitados sobre la interacción entre la infección por VIH y los PTE, y su efecto combinado sobre el NCI.Objetivo: En esta revisión sistemática sintetizamos evidencia del efecto combinado de la infección por VIH, PTEs y SLEs, y/o TEPT en el NCI de personas que viven con VIH/SIDA (PLWHA) en países de ingresos altos, medios y bajos.Método: Nuestros criterios de inclusión fueron estudios epidemiológicos observacionales (diseño de caso-control, cohortes y diseños transversales) que investigaron la interacción de la infección por VIH, PTEs y SLEs y/o TEPT, y específicamente su efecto combinado sobre el NCI en adultos. Se realizaron búsquedas en varias bases de datos electrónicas, que incluyeron a Pubmed/Medline, PsycINFO, Scopus y Global Health, utilizando los términos de búsqueda: cognición, VIH/SIDA, estudios de observación, trauma y permutaciones de los mismos.Resultados: Quince estudios se incluyeron en la revisión, de los cuales la mayoría se realizaron en países de altos ingresos. Diez de los quince estudios fueron realizados en los Estados Unidos de América (EE.UU.) y cinco en Sudáfrica. Siete de éstos se centraron en el estrés de la vida temprana/trauma infantil. Los estudios restantes evaluaron PTEs y SLEs cuya aparición fue en la vida adulta solamente. Ocho estudios incluyeron sólo mujeres. En general, los estudios sugieren que la exposición a PTE y SLE y/o TEPT es un factor de riesgo significativo para NCI en adultos que viven con VIH, con el deterioro en la memoria y las funciones ejecutivas como la consecuencia más probable de la exposición a PTE y SLE.Conclusión: Estos hallazgos resaltan la necesidad de la detección de traumas y la integración de intervenciones centradas en el trauma en la atención del VIH para mejorar sus resultados.

RESUMO

BACKGROUND: Broadening our knowledge of the longitudinal course of mood symptoms is cardinal to providing effective long-term treatments. Research indicates that patients with mental illness are willing to engage in the use of telemonitoring and mobile technology to assess and monitor their mood states. However, without the provision of distant support, adverse outcomes and events may be difficult to prevent and manage through self-monitoring. Understanding patient perspectives is important to achieving the best balance of self-monitoring, patient empowerment, and distant supporter involvement. METHODS: This systematic review synthesises quantitative and qualitative evidence of the effectiveness and feasibility of daily/weekly/monthly remote mood monitoring that includes distant support in participants with mood disorders. Inclusion criteria comprised mood monitoring of mood disorder patients as main intervention, study design, method of monitoring, and presence of psychotherapy and psychoeducation. Effectiveness was defined by the change in depression and/or mania scores. Feasibility was determined on participant feedback and completion/attrition rates. Studies were assessed for quality using the Mixed Methods Appraisal Tool version 2018. RESULTS: Nine studies of acceptable quality met the inclusion criteria. Distant mood monitoring was effective in improving depression scores but not mania scores. Feasibility, as measured through compliance and completion rates and participant feedback, varied. CONCLUSION: Distant mood monitoring with support may be a useful, acceptable, and feasible intervention for diverse groups of patients in terms of age and ethnicity. Further, it may be effective in improving symptoms of depression, increasing treatment adherence, and facilitating the prevention and management of adverse outcomes. As a task-shifting intervention, distant mood monitoring may help to alleviate the burden on mental health providers in developing countries.

BACKGROUND: Anxiety, mood, trauma- and stressor-related disorders confer increased risk for metabolic disease. Adiponectin, a cytokine released by adipose tissue is associated with these disorders and obesity via inflammatory processes. Available data describing associations with mental disorders remain limited and conflicted. METHODS: A systematic search was conducted for English, peer-reviewed articles from inception until February 2019 that assessed for serum or plasma adiponectin levels in adults with an anxiety, mood or trauma-related disorder. Diagnoses were determined by psychiatric interview, based on DSM-IV, DSM-5 or ICD-10 criteria. Analyses were performed using STATA 15 and Standardized mean difference (SMD) with 95% confidence interval was applied to pool the effect size of meta-analysis studies. RESULTS: In total 65 eligible studies were included in the systematic review and 30 studies in this meta-analysis. 19,178 participants (11,262 females and 7916 males), comprising healthy adults and adults with anxiety, mood and trauma-related disorders, were included. Overall results indicated an inverse association between adiponectin levels and examined mental disorders. Specifically, patients with an anxiety disorder (SMD  = -1.18 µg/mL, 95% CI, -2.34; -0.01, p â€Š= 0.047); trauma or stressor-related disorder (SMD â€Š= â€Š-0.34 µg/mL, 95% CI, -0.52; -0.17, p â€Š= 0.0000) or bipolar disorder (SMD  = â€Š-0.638 µg/mL, 95% CI, -1.16, -0.12, p â€Š= 0.017) had significant lower adiponectin levels compared to healthy adults. LIMITATIONS: Heterogeneity, potential publication bias, and lack of control for important potential confounders were significant limitations. CONCLUSION: Peripheral adiponectin levels appear to be inversely associated with anxiety, mood, trauma- and stressor related disorders and may be a promising biomarker for diagnosis and disease monitoring.

RESUMO

BACKGROUND: Trauma exposure is associated with the development of mood disorders and their phenotypic presentation. Cross-sectional associations between trauma exposure and mood disorders are well documented. Data on the association of trauma with longitudinal mood trajectories are lacking. We investigated the association between trauma exposure and weekly mood trajectories. METHOD: Mood disorder patients (N = 107; female = 81; mean age = 37.04 years), assessed for trauma exposure at baseline using the Childhood Trauma Questionnaire (CTQ) and Life Events Checklist (LEC), completed weekly telephonic mood assessments using the Quick Inventory of Depressive Symptomatology (QIDS) and Altman Self-Rating Mania scale (ASRM) over a 16 week period commencing at one week post-discharge from hospital. Associations between trauma exposure, severity of mood symptoms and mood trajectories were analysed using Pearson's correlations, LS Mean scores, F-statistics, and RMANOVA. RESULTS: Trauma exposure was persistently associated, albeit with some fluctuation in the strength of the association, with depressive symptomatology. Emotional abuse showed the most persistent association over time. Sexual abuse was minimally associated with depressive symptomatology. The severity of childhood trauma exposure was positively correlated with the severity of depressive symptoms. Lifetime traumatic events were significantly associated with mania scores, however there was no association between childhood trauma exposure and mania symptoms. CONCLUSION: Identification of both a history of childhood abuse and neglect and lifetime traumatic event exposure is important in the assessment and management of patients with mood disorders, as trauma can exert a persistent impact on depression trajectories and on symptom severity.

RESUMO

Despite the progress made in HIV treatment and prevention, HIV remains a major cause of adolescent morbidity and mortality in sub-Saharan Africa. As perinatally infected children increasingly survive into adulthood, the quality of life and mental health of this population has increased in importance. This review provides a synthesis of the prevalence of mental health problems in this population and explores associated factors. A systematic database search (Medline, PsycINFO, Scopus) with an additional hand search was conducted. Peer-reviewed studies on adolescents (aged 10-19), published between 2008 and 2019, assessing mental health symptoms or psychiatric disorders, either by standardized questionnaires or by diagnostic interviews, were included. The search identified 1461 articles, of which 301 were eligible for full-text analysis. Fourteen of these, concerning HIV-positive adolescents, met the inclusion criteria and were critically appraised. Mental health problems were highly prevalent among this group, with around 25% scoring positive for any psychiatric disorder and 30-50% showing emotional or behavioral difficulties or significant psychological distress. Associated factors found by regression analysis were older age, not being in school, impaired family functioning, HIV-related stigma and bullying, and poverty. Social support and parental competence were protective factors. Mental health problems among HIV-positive adolescents are highly prevalent and should be addressed as part of regular HIV care.
