RESUMEN
Background: Trauma exposure prevalence and consequent post-traumatic stress disorder among South African adolescents are significant. Sleep disturbances are among the most frequently reported difficulties faced by those dealing with PTSD. The current study examined the feasibility and preliminary efficacy of the South African Adolescence Group Sleep Intervention on PTSD symptom severity and sleep disturbance.Method: Sixty-one adolescents with PTSD diagnoses and sleep disturbance were randomly assigned (1:1) to one individual and four group sessions of a sleep intervention (SAASI) or a control group. Participants completed the Child PTSD symptom scale for DSM5 (CPSS-5) and the Pittsburgh Sleep Quality Index (PSQI) among other sleep and psychiatric measures. The trial was registered on the Pan African Trial Registry (PACTR202208559723690).Results: There was a significant but similar decrease in PSQI scores in both groups over time indicating no overall intervention effect (Wald test = -2.18, p = .029), mean slope = -0.2 (95% CI: -0.37 to -0.02) (p = .583). On the CPSS-5, interaction between groups was also not significant (p = .291). Despite this overall finding, the mean difference in CPSS-SR-5 scores increased over time, with the difference between groups post-treatment -9.10 (95%CI: -18.00 to -0.21), p = .045 and the 1-month follow-up contrast - 11.22 (95%CI: -22.43 to -0.03), p = .049 suggesting that PTSD symptom severity decreased more in the intervention group than the control group. The dropout rate was higher than expected for both the intervention (n = 10; 32%) and control (n = 8; 26.7%) groups. Dropout were mostly school commitments or travel related.Conclusions: Early findings suggest a trend towards dual improvement in sleep quality and PTSD symptom severity in adolescents with a sleep disturbance and PTSD receiving a group sleep intervention (SAASI). Further investigation in a properly powered RCT with detailed retention planning is indicated.
A four-week group sleep intervention seems feasible in adolescents with PTSD and sleep disturbances in a low-resource South African setting.Utilising less specialised mental health resources such as nurses and counsellors in intervention delivery was feasible and effective.Preliminary results are promising and support further research to establish the efficacy of the intervention.

We explored participants' experiences of a counsellor-supported PTSD Coach mobile application intervention (PTSD Coach-CS) in a randomised controlled trial. PTSD Coach-CS participants, who received the intervention and self-completed a custom-designed questionnaire at intervention completion were included (n = 25; female = 20; ages 19-59; isiXhosa = 22). This questionnaire comprised questions regarding the feasibility, acceptability and potential impact of the PTSD Coach-CS intervention, and general psychological support in our setting. Data were analysed using Braun and Clarke's thematic analysis. Three main themes emerged. (i) Participants' largely positive experiences of treatment procedures included the safe space created by the counsellor support in combination with the PTSD Coach application, allowing them to learn about and understand their lived experiences, and to accept their PTSD diagnoses. (ii) Positive perceptions of the PTSD Coach application, yet raising important concerns (e.g., lack of family involvement) for future consideration. (iii) Intervention-specific and systemic treatment barriers (e.g., stigma) providing important information to inform and increase the usefulness of the PTSD Coach-CS intervention. The findings suggest that the PTSD Coach-CS intervention may help address the need for access to suitable care for South African adults with PTSD. Some contextual barriers must be considered in further intervention implementation.
RESUMEN
To widen treatment access for posttraumatic stress disorder (PTSD) in resource-constrained South Africa, we evaluated the feasibility and effectiveness of a counsellor-supported PTSD Coach mobile application (app) (PTSD Coach-CS) intervention on PTSD and associated sequelae in a community sample. Participants (female = 89%; black = 77%; aged 19-61) with PTSD were randomised to PTSD Coach-CS (n = 32) or enhanced Treatment-as-Usual (n = 30), and assessed with the Clinician-Administered PTSD Scale (CAPS-5), PTSD Checklist (PCL-5) and Depression, Anxiety and Stress Scale-21 items, at pre- to post-treatment and follow-up (1 and 3 months). We also collected data on user experiences of the PTSD Coach app with self-administered surveys. We conducted an intent-to-treat analysis and linear mixed models. A significant (group × time) effect for the CAPS-5 (F3.136 = 3.33, p = 0.02) indicated a greater reduction in PTSD symptom severity over time for the intervention group with a significant between-group effect size detected at 3-month follow-up. Significant between-group effect sizes were detected in self-reported stress symptom reduction in the intervention group at post-treatment and 3-month follow-up. Participants perceived the app as helpful and were satisfied with the app. Findings suggest PTSD Coach-CS as a suitable low-cost intervention and potential treatment alternative for adults with PTSD in a resource-constrained country. Replication in larger samples is needed to fully support effectiveness. Pan African Trial Registry: PACTR202108755066871.
RESUMEN
BACKGROUND: Executive function (EF) deficits are common in adults with post-traumatic stress disorder (PTSD). Macro- and micronutrient intake are potential modifiable factors that may influence EF in PTSD. OBJECTIVES: To explore the relationship between the daily dietary intake of ω-3 and ω-6 polyunsaturated fatty acids (PUFAs), vitamin C, vitamin E, vitamin D, vitamin B12 and folate, and EF in adults with PTSD. METHODS: This was a cross-sectional observational study of adults with PTSD who completed neurocognitive assessments (n = 201). Digit span backwards, spatial span backwards, Stroop test and the Ruff Figural Fluency Task were used to assess EF. FoodFinder nutrient intake based on 24-h dietary recalls was used to calculate average daily nutrient intake. Multivariable linear regression models were used to regress EF on the nutrient variables. RESULTS: Intake of vitamin E, ω-3 PUFAs, and ω-6 PUFAs were all positively associated with planning and set-shifting, with vitamin E (adjusted ß = 0.20, p = 0.004) and ω-6 (adjusted ß = 0.17, p = 0.01) remaining significant after adjustment for age; sex; education and body mass index. Vitamin D intake was negatively associated with interference (adjusted ß = -0.21, p = 0.01). Vitamin C, vitamin B12 and folate intake were not associated with EF. LIMITATIONS: 24-h dietary recall data is limited by recall bias. Circulating nutrient levels were not measured. CONCLUSIONS: Dietary intake of vitamins E, ω-3 and ω-6 may be important modifiable factors affecting EF in adults with PTSD. Randomised controlled trials are needed to investigate whether micro- and macronutrient interventions can improve EF and other outcomes in PTSD.

BACKGROUND: Pregnant women participated in multifaceted case management (MCM) to prevent Fetal Alcohol Spectrum Disorders (FASD). METHODS: Women recruited from antenatal clinics for a longitudinal child development study were screened for alcohol use. Forty-four pregnant women were defined as high-risk drinkers on the Alcohol Use Disorder Identification Test (AUDIT) by an AUDIT score ≥8 and participated in 18 months of MCM to facilitate reduction or cessation of alcohol consumption. Forty-one women completed MCM. Fifty-five equally high-risk women who received standard antenatal care comprised the comparison/control group. Development in offspring was evaluated by a blinded interdisciplinary team of examiners through 5 years of age. RESULTS: At five years of age, more children (34%) of MCM participating women did not meet the criteria for FASD vs. non-MCM offspring (22%). Furthermore, a statistically significant (p = .01) lower proportion of MCM offspring (24%) was diagnosed with fetal alcohol syndrome (FAS) compared to controls (49%). Children of MCM participants had significantly (p < .05) better physical outcomes: lower total dysmorphology scores, larger head circumferences, longer palpebral fissures, and higher midfacial measurements. Neurodevelopment results showed mixed outcomes. While Bayley developmental scores indicated that MCM offspring were performing significantly worse on most domains through 18 months, group scores equalized and were not significantly different on Kaufman Assessment Battery neurobehavioral measures by five years. Regression analyses indicated that offspring of women who received standard antenatal care were associated with significantly more negative outcomes than MCM offspring: a diagnosis of FAS (OR = 3.2; 95% CI: 1.093-9.081), microcephaly (OR = 5.3; 95% CI: 2.1-13.5), head circumference ≤10th centile (OR = 4.3; 95%CI: 1.8-10.4), and short palpebral fissures (OR = 2.5; 95% CI: 1.0-5.8). CONCLUSION: At age five, proportionally fewer children of MCM participants qualified for a diagnosis of FAS, and proportionally more had physical outcomes indicating better prenatal brain development. Neurobehavioral indicators were not significantly different from controls by age five.KEY MESSAGESMultifaceted Case Management (MCM) was designed and employed for 18 months during the prenatal and immediate postpartum period to successfully meet multiple needs of women who had proven to be very high risk for birthing children with fetal alcohol spectrum disorders (FASD).Offspring of the women who participated in MCM were followed up through age five years and were found to have significantly better physical outcomes on multiple variables associated with fetal alcohol syndrome (FAS) and FASD, such as larger head circumferences and fewer minor anomalies, than those children born to equally at-risk women not receiving MCM.Fewer children of women receiving MCM were diagnosed with FASD than the offspring of equally-at-risk controls, and significantly (p = .01) fewer MCM offspring had FAS, the most severe FASD diagnosis.

Background: The high prevalence of trauma exposure and consequent post-traumatic stress disorder (PTSD) is well documented in low- and middle-income countries, and most individuals with PTSD have limited access to treatment in these settings. Freely available internet-based interventions, such as PTSD Coach (web-based and mobile application), can help to address this gap and improve access to and efficiency of care. Objective: We conducted two pilot studies to evaluate the feasibility, acceptability, and preliminary effectiveness of PTSD Coach in a South African resource-constrained context. Method: Pilot 1: Participants with PTSD (n = 10) were randomized to counsellor-supported PTSD Coach Online (PCO) or enhanced treatment as usual. Pilot 2: Participants (n = 10) were randomized to counsellor-supported PTSD Coach Mobile App or self-managed PTSD Coach Mobile App. Feasibility and acceptability were assessed by comparing attrition rates (loss to follow-up), reviewing participant and counsellor feedback contained in fieldnotes, and analysing data on the 'Perceived helpfulness of the PTSD Coach App' (Pilot 2). PTSD symptom severity was assessed with the Clinician Administered PTSD Scale for DSM-5 (CAPS-5), changes between treatment and control groups were compared, the reliable change index (RCI) was calculated, and clinically significant changes were determined. Results: Three participants in Pilot 1 and two participants in Pilot 2 were lost to follow-up. Fieldnotes indicated that PTSD Coach Mobile App addressed identified computer literacy challenges in Pilot 1 (PCO); and a shorter duration of intervention (from 8 to 4 weeks) was associated with less attrition. The RCI indicated that four participants in Pilot 1 and eight participants in Pilot 2 experienced significant improvement in PTSD symptom severity. Conclusions: The preliminary results suggest that both platforms can alleviate PTSD symptoms, and that the involvement of volunteer counsellors is beneficial. The use of PTSD Coach Mobile App may be more feasible than the online version (PCO) in our setting. HIGHLIGHTS Research on supported PTSD Coach interventions is limited in resource-constrained settings.Both volunteer counsellor-supported PTSD Coach Online and the PTSD Coach Mobile App showed preliminary reliable and clinically significant changes.The use of PTSD Coach Mobile App seems more feasible than the volunteer counsellor-supported PTSD Coach Online.
Antecedentes: La alta prevalencia de exposición a trauma y el consecuente trastorno de estrés postraumático (TEPT) están bien documentadas en países de bajos y medianos ingresos y la mayoría de los individuos con TEPT tiene acceso limitado a los tratamientos necesarios en estos entornos. Las intervenciones basadas en internet de acceso gratuito, como el 'PTSD Coach', nombre de la aplicación en inglés (disponible vía aplicación móvil y a través de la web), pueden ayudar a abordar esta brecha y mejorar el acceso y la eficiencia de la atención. Condujimos dos estudios piloto para evaluar la viabilidad, aceptabilidad y preliminarmente la efectividad del 'PTSD Coach' en un contexto con recursos limitados de Sudáfrica.Metodología: Piloto 1: Los participantes con TEPT (n = 10) fueron asignados al azar al 'PTSD Coach' en modalidad online (PCO en sus siglas en inglés) apoyado por un consejero o al tratamiento habitual mejorado. Piloto 2: Los participantes (n = 10) fueron asignados al azar al 'PTSD Coach' en modalidad de aplicación móvil apoyado por un consejero o a la aplicación móvil 'PTSD Coach' de manera auto-gestionada. La viabilidad y aceptabilidad se evaluaron comparando las tasas de deserción (perdida durante el seguimiento), revisando los comentarios de retroalimentación dados por los participantes y consejeros, los cuales se encontraban contenidos en las notas de campo, y analizando los datos en la 'Utilidad percibida de la aplicación PTSD Coach' (Piloto 2). La gravedad de los síntomas del TEPT se evaluaron con la Escala de TEPT Administrada por el Clínico (CAPS-5), donde se compararon los cambios entre los grupos de tratamiento y control, el índice de cambio confiable fue calculado y el cambio clínicamente significativo fue determinado.Resultados: En el Piloto 1 se perdieron en el seguimiento tres participantes y en el Piloto 2 se perdieron en el seguimiento dos participantes. Las notas de campo indicaron que la aplicación móvil del 'PTSD Coach' abordó los desafíos de la alfabetización informática en el Piloto 1 (PCO); y una intervención de duración más breve (de ocho a cuatro semanas) se asoció con menos deserción. En el Piloto 1 el RCI indicó que cuatro participantes experimentaron una mejoría significativa en la gravedad de los síntomas del TEPT, mientras que ocho indicaron una mejoría significativa en la gravedad de los síntomas del TEPT en el Piloto 2.Conclusiones: Los resultados preliminares sugieren que ambas plataformas pueden aliviar los síntomas de TEPT y que la participación de un consejero voluntario es beneficiosa. La aplicación móvil 'PTSD Coach' puede ser más factible que la versión en línea (PCO) en nuestro medio.

Glucocorticoids and inflammatory markers can influence cognitive function. Hair cortisol concentrations (HCC) reflect longer-term hypothalamic pituitary adrenal (HPA) axis function and combined with immune markers can provide insights into how HPA-axis and immune pathways interact to influence cognition. We examined the association between HCC and high sensitivity c-reactive protein (hsCRP) levels, as well as the interaction between HCC and hsCRP, and cognitive function in a sample of 153 females, aged between 18 and 79 years, from a cross-sectional case-control study (SHARED ROOTS), conducted in Cape Town, South Africa from May 2014 until June 2017. We examined whether HCC and hsCRP levels were associated with performance on neurocognitive tests in both unadjusted and adjusted linear regression models. HCC demonstrated a significant inverse association with verbal working memory in both unadjusted (p = 0.010) and adjusted (p = 0.016) analyses. There were significant interactions between HCC and hsCRP on verbal intelligence (p = 0.016), language (p = 0.023) and executive function (p = 0.008) scores, such that at low HCC hsCRP levels were positively associated with language (p = 0.020) and executive function (p = 0.006) scores and at high HCC hsCRP levels were inversely associated with verbal intelligence (p = 0.034) scores. Though the results did not survive correction for multiple comparisons, they suggest stress-related neuroendocrine effects on working memory impairment. Furthermore, under physiological conditions and low long-term HCC, there may be positive effects of peripheral inflammatory markers on cognitive performance, whereas there may be detrimental effects when the HPA-axis is dysregulated as reflected by high long-term cortisol output.

BACKGROUND: Accurate perception of body weight is necessary for individuals with a high body mass index (BMI) to initiate strategies to improve their health status. Furthermore, identifying factors that influence accurate body weight perception can assist in designing appropriate educational and weight management programs. We therefore aimed to investigate whether levels of cognitive functioning and insight influence the ability to correctly judge body weight. METHODS: One hundred and eighty four overweight and obese adults who participated in a cross- sectional case-control study and were controls in the aforementioned study were included. The study was conducted in Cape Town, South Africa. Demographic, weight-related, neuropsychiatric, neurocognitive and cognitive insight measures were administered. Regression analysis was conducted to determine the factors associated with correct weight perception. RESULTS: The final regression model explained 52.3% of variation in accurate perception of body weight and was significant (p ≤ 0. 001). The model correctly classified 79.3% of individuals who were able to correctly and incorrectly judge their weight. Adults with higher BMI, and lower self-certainty, those who reported that they had gained weight in the previous year and those who were told by a healthcare professional to lose or maintain a healthy weight were more likely to correctly judge their weight. CONCLUSION: Some aspects of cognitive insight (self-certainty) but not cognitive functioning were associated with perception of body weight in this sample. Awareness of recent weight changes, higher BMI and advice from of health care professionals were also significantly associated with perception of body weight, while demographic variables were not. Understanding the factors that contribute to the correct perception of weight is important in identifying appropriate health interventions that may address the burden of associated non-communicable diseases in overweight and obese individuals.

This case series documents local experience using accelerated theta-burst repetitive transcranial magnetic stimulation (rTMS) as a supplementary treatment for depression in both major depressive disorder (MDD) and bipolar disorder (BD). Nine consenting patients (MDD = 7; BD = 2) each received 20 accelerated theta-burst sessions over 8 days. Improvement was monitored using the Centre for Epidemiological Studies Depression (CES-D) Scale and the Clinical Global Impression (CGI) Scale at baseline, at day 5 and at day 8 of rTMS treatment. We performed a Wilcoxon matched-pairs signed-rank test to determine whether there was a difference in scores from baseline to post-treatment. The CES-D scores decreased significantly from baseline to post-treatment (Z = -2.547, p = 0.011) with five patients experiencing at least a 50% symptom reduction on the CES-D. CGI severity scores also decreased significantly between baseline and post-treatment (Z = -2.547, p = 0.011). The most commonly reported adverse effect was mild headaches, lasting a few hours during and after rTMS treatment. The findings suggest that the accelerated theta-burst rTMS protocol for depression is well tolerated with most patients also experiencing symptomatic improvement by day 8.
