ABSTRACT
PURPOSE: This report provides the results of a task-shared approach for integrating care for perinatal depression (PND) within primary maternal and child healthcare (PMCH), including the factors that may facilitate or impede the process. METHODS: This hybrid implementation-effectiveness study guided by the Replicating Effective Programmes framework was conducted in 27 PMCH clinics in Ibadan, Nigeria. The primary implementation outcome was change in the identification rates of PND by primary health care workers (PHCW) while the primary effectiveness outcome was the difference in symptom remission (EPDS score ≤ 5) 6 months postpartum. Outcome measures were compared between two cohorts of pregnant women, one recruited before and the other after training PHCW to identify and treat PND. Barriers and facilitators were explored in qualitative interviews. RESULTS: Identification of PND improved from 1.4% before to 17.4% after training; post-training rate was significantly higher in clinics where PHCW routinely screened using the 2-item patient health questionnaire (24.8%) compared to non-screening clinics (5.6%). At 6-months postpartum, 60% of cohort one experienced remission from depression, compared to 56.5% cohort two [OR-0.9 (95%CI-0.6, 1.3) p = 0.58]. Identified facilitators for successful integration included existence of policy specifying mental health as a component of PHC, use of screening to aid identification and supportive supervision, while barriers included language and cultural attitudes towards mental health and human resource constraints. PHCW were able to make adaptations to address these barriers. CONCLUSIONS: Successful implementation of task-shared care for perinatal depression requires addressing staff shortages and adopting strategies that can improve identification by non-specialist providers. TRIAL REGISTRATION: This study was retrospectively registered 03 Dec 2019. https://doi.org/10.1186/ISRCTN94230307 .
ABSTRACT
OBJECTIVES: There is a knowledge gap on resilience and its impact on mental health of Africans who survive a stroke. We describe the trajectory of psychological resilience and its association with depression and quality of life (QoL) across the first poststroke year in Nigeria. METHOD: Prospective observational study of 150 survivors of a first ever stroke. Resilience was ascertained at 3 time-points prospectively over 12 months using the 25-items Resilience Scale (RS). Depression and QoL were also assessed at baseline and follow-up, respectively using the centre for epidemiologic studies depression scale (CES-D 10) and health related quality of life in stroke patients (HRQOLISP-26). Associations were investigated using regression models and presented as adjusted odds ratios (OR) and Wald test coefficients within 95% confidence intervals (CI). RESULTS: Resilience improved across time points of measurement (p < 0.001). In multivariate logistic regression analyses adjusted for the effect of age, education, alcohol use, and hypertension, higher resilience was associated with male sex (OR = 5.3, 95% CI= 1.7, 17.2), younger age (OR = 4.8, 95% CI = 1.5,15.7), and baseline hypertension (OR= 0.2, 95% CI ≤ 0.1,0.8). In similarly adjusted mixed effect linear regression analyses, higher resilience was associated with improvement in depression (months 12= -4.2, 95% CI= -5.6, -2.8) and quality of life (months twelve = 5.2, 95% CI = 2.2, 8.2) overtime. CONCLUSION: Resilience, which was associated with better mental health and wellbeing of stroke survivors, was less likely with hypertension. Results suggest an important role for control of vascular risk factors as part of resilience interventions to promote poststroke recovery.
ABSTRACT
INTRODUCTION: The LIfestyle for BRAin Health (LIBRA) index yields a dementia risk score based on modifiable lifestyle factors and is validated in Western samples. We investigated whether the association between LIBRA scores and incident dementia is moderated by geographical location or sociodemographic characteristics. METHODS: We combined data from 21 prospective cohorts across six continents (N = 31,680) and conducted cohort-specific Cox proportional hazard regression analyses in a two-step individual participant data meta-analysis. RESULTS: A one-standard-deviation increase in LIBRA score was associated with a 21% higher risk for dementia. The association was stronger for Asian cohorts compared to European cohorts, and for individuals aged ≤75 years (vs older), though only within the first 5 years of follow-up. No interactions with sex, education, or socioeconomic position were observed. DISCUSSION: Modifiable risk and protective factors appear relevant for dementia risk reduction across diverse geographical and sociodemographic groups. HIGHLIGHTS: A two-step individual participant data meta-analysis was conducted. This was done at a global scale using data from 21 ethno-regionally diverse cohorts. The association between a modifiable dementia risk score and dementia was examined. The association was modified by geographical region and age at baseline. Yet, modifiable dementia risk and protective factors appear relevant in all investigated groups and regions.

OBJECTIVES: Delirium has been rarely studied in older West Africans. We sought to investigate its correlates and outcomes in hospitalized older Ghanaians. METHODS: This was a one-month prospective observational study. Delirium prevalence was assessed within 24 h of admission using the Confusion Assessment Method (CAM). Incident delirium was determined with repeat CAM assessments on post-admission days 4, 7, 14, 21 and 28, after censoring participants with prevalent delirium. Multivariate logistic regression analyses were used to explore risk factors. Estimates of adjusted hazard ratios for mortality were derived with the discrete time version of the Cox regression model for time invariant explanatory variables. RESULTS: Among 483 participants, 250 (51.8%, 95% CI: 47.3-56.3) had prevalent delirium while 10 of the remaining 233 (4.3%, 95% CI: 2.1-7.8) developed incident delirium. Being older than 80 years (adjusted odds ratio (OR) = 2.1, 95% CI: 1.2-3.6), having no formal education (OR = 2.2, 95% CI: 1.4-3.4), stroke (OR = 1.8, 95% CI: 1.1-3.0), infection (OR = 1.9, 95% CI: 1.2-3.0), and high Triage Early Warning Score (OR = 6.9, 95% CI: 2.5-19.0) predicted delirium. Delirium (adjusted hazard ratio (HR) = 1.8, 95% CI: 1.0-3.3) and high TEWS (HR = 4.6 (95% CI: 1.7-12.7) at baseline predicted mortality. These factors also predicted longer hospital stay. CONCLUSION: Over half of hospital-treated older Ghanaians in the present study had delirium on the first day of admission. The syndrome prolonged hospitalisation and increased mortality risk. Future studies in West Africa may investigate the epidemiology of delirium in primary care and community settings.

INTRODUCTION: Though consistent evidence suggests that physical activity may delay dementia onset, the duration and amount of activity required remains unclear. METHODS: We harmonized longitudinal data of 11,988 participants from 10 cohorts in eight countries to examine the dose-response relationship between late-life physical activity and incident dementia among older adults. RESULTS: Using no physical activity as a reference, dementia risk decreased with duration of physical activity up to 3.1 to 6.0 hours/week (hazard ratio [HR] 0.88, 95% confidence interval [CI] 0.67 to 1.15 for 0.1 to 3.0 hours/week; HR 0.68, 95% CI 0.52 to 0.89 for 3.1 to 6.0 hours/week), but plateaued with higher duration. For the amount of physical activity, a similar pattern of dose-response curve was observed, with an inflection point of 9.1 to 18.0 metabolic equivalent value (MET)-hours/week (HR 0.92, 95% CI 0.70 to 1.22 for 0.1 to 9.0 MET-hours/week; HR 0.70, 95% CI 0.53 to 0.93 for 9.1 to 18.0 MET-hours/week). DISCUSSION: This cross-national analysis suggests that performing 3.1 to 6.0 hours of physical activity and expending 9.1 to 18.0/MET-hours of energy per week may reduce dementia risk.

BACKGROUND: There is limited information on new onset poststroke dementia (NPSD) in sub-Saharan Africa (SSA). We estimated incidence, cumulative incidence, risk factors and outcome of NPSD at 1 year in Nigerian survivors of a first-ever stroke. METHODS: Hospital-based prospective observational study. Assessments for global cognition, learning, memory, executive and activities of daily life (ADL) functioning were conducted at 3 poststroke timepoints (Baseline, 3- and 12 months). NPSD was ascertained according to the "National Institute of Neurological Disorders and Stroke and the Association Internationale pour la Recherche et l'Enseignement en Neurosciences (NINDS-AIREN) criteria." Outcomes were assessed using the modified Rankin Scale (mRS), center for epidemiologic studies depression scale (CES-D 10), health related quality of life in stroke patients (HRQOLISP-26) and caregivers strain index (CSI). RESULTS: Among 144 stroke survivors who were free of dementia at baseline, we found a 1-year cumulative incidence of 4.52% (95% C.I = 3.20, 6.39). In multivariate Cox regression analyses, diabetes was associated with NPSD (Hazard Ratio = 2.10, 95% CI = 1.02, 4.35). NPSD at 3 months was independently associated with motor decline [Mean difference (MD) in mRS = 1.6, 95% C.I = 0.9, 2.3)], depression (MD in CES-D = 2.9, 95% C.I = 0.3, 5.4), caregivers burden (MD in CSI = 1.2, 95% C.I = 0.5, 1.8), and poor quality of life (MD in HRQOLISP-26 = -11.2, 95% C.I = -15.7, -6.8) at 1 year. CONCLUSION: Approximately 4.5% of stroke survivors in Nigeria had NPSD at 1 year. Diabetes, which can be prevented, represent a primary prevention target for NPSD and its consequences in SSA.

To examine the prevalence as well as the clinical and psychosocial factors associated with depression and depression severity in pregnant adolescents. Participants were consecutively registered pregnant adolescents presenting to 30 selected primary maternal and child healthcare centers in Ibadan, Nigeria, who were screened for enrolment into an intervention trial for perinatal depression (depression defined as a score of ≥ 12 on the Edinburg Postnatal Depression Scale [EPDS] and met the DSM-IV diagnostic criteria for depression). Of the 1359 pregnant adolescents screened, 246 (18.1%) had depression. Mean age was 18.4 (sd 1.00), 58.9% were either married or cohabiting, 91.4% were primipara, and the mean gestational age was 23.8 weeks (sd 5.4 weeks). Food insecurity (going to bed hungry at least once in the previous week because there was no food to eat) was reported by 13.3%. In bivariate analysis, younger age, not living with a partner, unemployment, and food insecurity were associated with depression. In bivariate analysis, younger age, not living with a partner, unemployment and food insecurity were associated with depression, while younger age, being single and food insecurity were independently associated with being depressed in multivariate analysis. Severity of depression was related to age, higher anxiety and disability scores, lower quality of life scores across all domains and poorer attitudes towards pregnancy. Depression was associated with indices of higher social disadvantage among adolescents. Delaying childbearing and measures aimed at alleviating poverty may be important in preventing depression in this vulnerable group.

OBJECTIVES: Anti-police (#EndSARS) protests took place in October 2020 across several Nigerian cities, resulting in deaths, injuries and loss of property, but the psychological sequelae of these protests have not been studied. METHOD: In a cross-sectional online survey, we collected data on psychiatric morbidity and potential risk factors from 426 Nigerian social media users, who self-identified as participants or non-participants in a recent anti-police protest. RESULTS: We found elevated rates of psychiatric morbidity, with worse outcomes for protesters compared to non-protesters (psychological distress [44.2% vs 29.8%], depression [26.0% vs 14.9%], anxiety [51.0% vs 29.8%], post-traumatic stress disorder [7.4% vs 1.8%], current substance use [11.2% vs 4.5%] and suicidal ideation [7.1% vs 4.4%], respectively). After adjusting for the effects of COVID-19 pandemic and previous mental health diagnosis, the predictors of poor mental health among non-protesters were being unmarried (odds ratio = 7.4, p = 0.01) and low resilience (odds ratio range = 4.1-5.4, p < 0.03) while for the protesters, the predictors were low resilience (odds ratio range = 2.9-4.7, p < 0.01), being from Northern Nigeria (odds ratio = 4.7, p < 0.01) or residing in Northern Nigeria (odds ratio = 2.8, p = 0.03), being under-/unemployed (odds ratio range = 2.1-2.5, p < 0.04), holding the view that the protest was caused by the state of the economy (odds ratio = 2.0, p = 0.01), belief that the protest had a direct negative impact on the protester (odds ratio = 2.3, p = 0.04) and willingness to participate in future protests (odds ratio = 4.13, p = 0.02). CONCLUSION: We conclude that participating in the #EndSARS protest was associated with significant psychiatric morbidity. There is need to recognise and address the mental health sequelae of collective actions, and invest in programmes that build resilience and address socio-political determinants of mental health, especially with a focus on youth.

PURPOSE: This paper describes the design of a theory-informed pragmatic intervention for adolescent perinatal depression in primary care in Nigeria. METHODS: We conducted Focus Group Discussions (FGDs) among 17 adolescent mothers and 25 maternal health care providers with experience in the receipt and provision of care for perinatal depression. The Consolidated Framework for Implementation Research (CFIR) was used to systematically examine the barriers and facilitators affecting adolescent mothers' use of an existing intervention package for depression. The Theoretical Domain Framework (TDF) and the Capability, Opportunity, Motivation, Behaviour (COM-B) model were used to analyze the results of the data across the five CFIR domains. RESULTS: FGD analysis revealed that care providers lacked knowledge on approaches to engage young mothers in treatment. Young mothers had poor treatment engagement, low social support, and little interest in parenting. A main characteristic of the newly designed intervention is the inclusion of age-appropriate psychoeducation supported with weekly mobile phone calls, to address treatment engagement and parenting behaviours of young mothers. Also in the outer setting, low social support from relatives was addressed with education, "as need arises" phone calls, and the involvement of "neighborhood mothers". In the inner settings, care providers' behaviour is addressed with training to increase their capacity to engage young mothers in treatment. CONCLUSION: A theory-based approach helped develop an age-appropriate intervention package targeting depression and parenting skills deficit among perinatal adolescents in primary maternal care and in which a pragmatic use of mobile phone was key.

OBJECTIVES: We compared the trajectory of activities of daily living (ADL) in a nationally representative sample of older Nigerians with their Spanish peers and identified factors to explain country-specific growth models. METHODS: Data from two household multistage probability samples were used, comprising older adults from Spain (n = 2,011) and Nigeria (n = 1,704). All participants underwent assessment for ADL. Risk factors including sex, household income, urbanicity, years of education, depression, alcohol consumption and smoking were assessed using validated methods. State-space model in continuous time (SSM-CT) methods were used for trajectory comparison. RESULTS: Compared with Nigerians (µADL80=0.44, SE = 0.015, p < 0.001), Spanish older adults had higher disability scores (µADL80=1.23, SE = 0.021, p < 0.001). In SSM-CT models, the rate of increase in disability was faster in Nigerians (Nigeria: ß = 0.061, p<.01; Spain: ß = 0.028, p < 0.010). An increasing course of disability in the Spanish sample was predicted by female sex, lower education and depression diagnosis. CONCLUSION: The rate of increase in disability was faster in older Nigerians living in an economically disadvantaged context.

BACKGROUND: Traditional and faith healers (TFH) provide care to a large number of people with psychosis in many sub-Saharan African countries but they practise outside the formal mental health system. We aimed to assess the effectiveness and cost-effectiveness of a collaborative shared care model for psychosis delivered by TFH and primary health-care providers (PHCW). METHODS: In this cluster-randomised trial in Kumasi, Ghana and Ibadan, Nigeria, we randomly allocated clusters (a primary care clinic and neighbouring TFH facilities) 1:1, stratified by size and country, to an intervention group or enhanced care as usual. The intervention included a manualised collaborative shared care delivered by trained TFH and PHCW. Eligible participants were adults (aged ≥18 years) newly admitted to TFH facilities with active psychotic symptoms (positive and negative syndrome scale [PANSS] score ≥60). The primary outcome, by masked assessments at 6 months, was the difference in psychotic symptom improvement as measured with the PANSS in patients in follow-up at 3 and 6 months. Patients exposure to harmful treatment practices, such as shackling, were also assessed at 3 and 6 months. Care costs were assessed at baseline, 3-month and 6-month follow-up, and for the entire 6 months of follow-up. This trial was registered with the National Institutes of Health Clinical Trial registry, NCT02895269. FINDINGS: Between Sept 1, 2016, and May 3, 2017, 51 clusters were randomly allocated (26 intervention, 25 control) with 307 patients enrolled (166 [54%] in the intervention group and 141 [46%] in the control group). 190 (62%) of participants were men. Baseline mean PANSS score was 107·3 (SD 17·5) for the intervention group and 108·9 (18·3) for the control group. 286 (93%) completed the 6-month follow-up at which the mean total PANSS score for intervention group was 53·4 (19·9) compared with 67·6 (23·3) for the control group (adjusted mean difference -15·01 (95% CI -21·17 to -8·84; 0·0001). Harmful practices decreased from 94 (57%) of 166 patients at baseline to 13 (9%) of 152 at 6 months in the intervention group (-0·48 [-0·60 to -0·37] p<0·001) and from 59 (42%) of 141 patients to 13 (10%) of 134 in the control group (-0·33 [-0·45 to -0·21] p<0·001), with no significant difference between the two groups. Greater reductions in overall care costs were seen in the intervention group than in the control group. At the 6 month assessment, greater reductions in total health service and time costs were seen in the intervention group; however, cumulative costs over this period were higher (US $627 per patient vs $526 in the control group). Five patients in the intervention group had mild extrapyramidal side effects. INTERPRETATION: A collaborative shared care delivered by TFH and conventional health-care providers for people with psychosis was effective and cost-effective. The model of care offers the prospect of scaling up improved care to this vulnerable population in settings with low resources. FUNDING: US National Institute of Mental Health.

OBJECTIVES: There is a knowledge gap on the prognostic significance of subsyndromes of delirium. We describe the association of poststroke attenuated delirium syndrome (ADS) with cognitive, functional, and mortality outcomes at 3 months. METHODS: A longitudinal observational study in which repeated assessments for delirium symptoms were conducted in the first week of stroke using the confusion assessment method. Attenuated delirium syndrome was characterized in survivors who were free of the full delirium syndrome but had ≥2 core features of delirium. Baseline and follow-up assessments were conducted using the Mini-Mental State Examination (MMSE), 10-word list learning and delayed recall test, Animal naming test, and Barthel index. RESULTS: Among 150 participants recruited consecutively over 2 years, ADS was present in 32 (21.3%). Of 121 who were free of the full delirium syndrome, 21 (17.4%) had died by 3 months. Those who survived were more likely to be receiving treatment for systemic hypertension (88.5%, P = .007). In analyses adjusting for the effect of age, economic status, and systemic hypertension, ADS in the first week of stroke predicted cognitive decline at 3 months ([mean difference (MD) in MMSE scores = -3.8, 95% CI = -7.0 to -0.7, P = .019]). However, ADS was not associated with greater decline in activities of daily life (MD = -0.4, 95% CI = -2.8 to 2.0) or significant odds ratio (OR) of mortality (OR = 2.3, 95% CI = 0.8-6.3). CONCLUSION: Attenuated delirium syndrome may be an important marker of cognitive impairment at 3 months poststroke. Its detection may lead to identification of stroke survivors who are likely to benefit from evidence-based preventive interventions for poststroke cognitive decline.

OBJECTIVES: There is a knowledge gap on the impact of pre-existing cognitive decline on poststroke decline in indigenous Africans. We describe the trajectories of domain-specific cognitive and activities of daily life (ADL) functioning across the first year of stroke in Nigerians with pre-existing cognitive decline. MATERIALS AND METHODS: Prospective observational study. Prestroke cognitive decline was ascertained retrospectively using the 16-item Informant Questionnaire for Cognitive Decline in the Elderly (IQCODE). Assessments for global cognition, learning, memory, executive and ADL functioning were conducted at 3 time points using the Mini-Mental state examination (MMSE), 10-words list learning and delayed recall test (10 WDRT), Animal naming test and Barthel index, respectively. RESULTS: Among 150 stroke survivors, prestroke cognitive decline was found in 25 (16.7%, 95% C.I = 11.5%-23.6%). In linear regression analyses adjusting for the effect of age, education, stroke severity and comorbid diabetes mellitus, prestroke cognitive decline predicted poor memory scores at one year [Adjusted standardized mean difference (SMD) = -0.6, 95% C.I = -1.1, -0.1, p = 0.016)]. The association of prestroke cognitive decline with poststroke poor memory was substantially mediated by age (SMD = -0.9, 95% C.I = -1.4, -0.4, p < 0.001). CONCLUSION: Pre-existing cognitive decline in this sample was associated with an age-mediated poor memory function at one-year poststroke. Early institution of targeted cognitive rehabilitation in stroke survivors with pre-existing cognitive decline may reduce the neurocognitive burden of stroke in Black Africans.

OBJECTIVES: Few studies in Africa have investigated the risk profile and course of loneliness in old age. This study examined the risk factors for onset and chronicity, as well as the predictors of recovery from loneliness in a large representative sample of community dwelling older Africans. METHODS/DESIGN: A household multistage probability sample of Nigerians who were 65 years or older was drawn from a geographical area with approximately 25 million population. Loneliness was measured using the 3-item University of California (UCLA) scale in 2007 and annually in 2008 and 2009. Social engagement, social network, and depression were evaluated using the WHO Composite International Diagnostic Interview. Respondents were also administered the 30-item Geriatric Depression Scale. Multivariate logistic regression models were used to explore for risk factors. Estimates of adjusted hazard ratios (HR) for recovery were derived with the discrete time version of the Cox regression model for time invariant explanatory variables. RESULTS: Of 1704 respondents, 1525 were free of loneliness, using the UCLA scale, in 2007. A total of 209 (18.8%) persons developed new onset of loneliness in 2008 and 2009. Depression (O.R = 2.9, 95% C.I = 1.3-6.7), unmarried status (OR = 2.1, 95% C.I = 1.2-3.9) and social isolation (OR = 1.8, 95% CI = 1.0-3.2) independently predicted loneliness onset. Baseline demographic, health, social, and lifestyle factors were not associated with a chronic course of loneliness. The overall recovery rate estimated over two years was 89.5% (95% CI = 75.3-106.4). Being male (HR = 1.3, 95% C.I = 1.0-1.6), ≥80 years (HR = 1.4, 95% CI = 1.2-1.8) and having good social engagement at baseline (HR = 1.5, 95% C. = 1.1-2.0) independently predicted recovery from loneliness. CONCLUSIONS: Over a 2-year period, nearly one in five community-dwelling Africans developed new onset loneliness in old age, with a similar proportion having a chronic course of the emotional experience. While depression and indices of social isolation at baseline were associated with onset, good social engagement predicted recovery from loneliness.

OBJECTIVES: Prior neuropsychiatric disturbances are risk factors for stroke. There is a knowledge gap on the predictors of prestroke psychopathology, as well as their association with stroke outcomes in survivors living in low- and middle-income countries (LMICs). We estimated prevalence, predictors, and association of prestroke neuropsychiatric symptoms with poststroke depression (PSD), disability, and mortality. DESIGN: Prospective observation. SETTING: Nigeria. PARTICIPANTS: Adult ischemic and hemorrhagic stroke survivors. MEASUREMENTS: Prestroke psychopathology were ascertained using the Neuropsychiatric Inventory Questionnaire (NPI-Q). Outcomes were assessed using validated tools, including the Centre for Epidemiologic Studies - Depression Scale (CES-D 10) and modified Rankin scale (mRS). Independent associations were investigated using regression models with Bonferroni corrections, and presented as standardized mean differences (SMD) and odds ratios (OR) within 95% confidence intervals (CI). RESULTS: Among 150 participants, prestroke neuropsychiatric symptoms were found in 78 (52%). In multivariate logistic regression analyses, prestroke sleep disturbance was associated with systemic hypertension (OR = 5.39, 95% CI = 1.70-17.08). Prestroke neuropsychiatric symptoms independently predicted worse motor disability scores (SMD = 0.92, 95% CI = 0.21-1.62) and greater odds of poststroke mortality (OR = 2.7, 95% CI = 1.1-7.0) at 3 months. However, prestroke depression was not significantly associated with PSD. CONCLUSION: Prestroke sleep disturbances was associated with systemic hypertension, a key index of high cardiovascular risk profile and stroke. The findings should energize before-the-stroke identification and prioritization of limited treatment resources in LMICs to persons with sleep symptoms who have multiple, additional, risks of stroke.

BACKGROUND: Undetected acute phase delirium contributes to high poststroke mortality in sub-Saharan Africa (SSA). The present study adds to existing literature by examining the association of prestroke psychiatric symptoms with poststroke mortality at 3 and 12 months in Nigeria. METHODS: A prospective observational study with repeated delirium assessments conducted using the Confusion Assessment Method (CAM). Delirium was characterised in participants meeting criteria in the Fifth edition of the Diagnostic and Statistical Manual of mental disorders (DSM-V) as well as in those with ≥two core delirium features. Prestroke psychiatric symptoms were ascertained using the Neuropsychiatric Inventory Questionnaire (NPI-Q). Information on mortality was obtained by research supervisors during medical follow-up. Associations were investigated using multivariate logistic regression analyses and presented as odds ratios (O.R) within 95% confidence intervals (C.I). RESULTS: Forty-five (30%) of 150 participants who provided data in the first week of stroke died by one-year follow-up. Those who died were more likely to have had a prestroke psychiatric symptom (64.4%, p=0.005) and delirium in the acute phase (60.0%, p=0.002). In analyses adjusting for the effect of age, education, tobacco smoking and stroke severity, prestroke psychiatric symptoms (O.R=3.3, 95% C.I=1.3,8.2; O.R=2.2, 95% C.I=1.0,4.6) and acute phase delirium (O.R=3.1, 95% C.I= 1.2,7.6; O.R=3.4, 95% C.I=1.5, 7.6) predicted mortality at 3 and 12 months poststroke, respectively. CONCLUSION: This study found that prestroke psychiatric symptoms and acute phase delirium independently predicted post-stroke mortality at 3- and 12 months. Detection and treatment of mental health conditions in the population at increased risk of stroke may help reduce poststroke mortality in SSA.

BACKGROUND: Persons of African ancestry are thought to carry a higher risk for extrapyramidal syndromes (EPS) in schizophrenia. AIM: We investigated the phenomenon of spontaneous and treatment-emergent EPS in a sample comprising Xhosa (South Africa) and Yoruba (Nigeria) Africans with first-episode schizophrenia and first exposure to antipsychotics. METHODS: The Extrapyramidal Symptom Rating Scale (ESRS) and a variety of validated tools were used for the assessment of participants before, and two-weekly after treatment with low dose flupenthixol decanoate. Participants were followed up for 12 months. Association of EPS with clinical characteristics was investigated using Pearson's correlation and linear regression analyses. RESULTS: Of 88 participants at baseline, 16 (18.1%) had at least one definite EPS prior to antipsychotic exposure and 34 (38.6%) had treatment-emergent EPS. While spontaneous Parkinsonism was associated with negative symptoms (r = 0.2, p = 0.043; ß = 0.6, p = 0.043), treatment-emergent EPS demonstrated non-significant correlations with clinical characteristics. Apart from dyskinesia, the frequency of treatment-emergent EPS decreased over 12 months observation. CONCLUSION: These findings support the hypothesis suggesting that spontaneously occurring Parkinsonism in schizophrenia may be the motor spectrum of negative symptomatology. Future studies of this relationship may lead to early identification of patients who may be more sensitive to EPS.

BACKGROUND: The concept of European psychologisation of depression versus somatisation in non-European populations has been the basis of several studies of cultural psychopathology in the general population. Little is currently known about cross-cultural differences and similarities in late-life depression symptom reporting. We cross-culturally compared symptom reporting in the context of Major Depressive Disorder (MDD) among community-dwelling older adults from Spain and Nigeria. METHODS: We relied on data from two household multistage probability samples comprising 3,715 persons aged 65 years or older in the Spanish and Nigerian populations. All participants underwent assessments for MDD using the World Mental Health Survey version of the Composite International Diagnostic Interview. Cross-cultural comparison of broad somatic and psychological categories as well as relationship and influence of individual symptoms were analysed using the Symptom Network Analysis approach. RESULTS: Current MDD was diagnosed in 232 and 195 older persons from Spain and Nigeria, respectively. The symptom network of the two samples were invariant in terms of global strength, S(GSPAIN , GNIGERIA ) = 7.56, P = .06, with psychological and somatic symptoms demonstrating centrality in both countries. However, country-specific relationships and influence of individual symptoms were found in the network structure of both samples, M(GSPAIN , GNIGERIA ) = 2.95, P < .01. CONCLUSION: Broad somatic and psychological symptoms categories contributed to the structural network of older Africans and their peers from the Spanish population. Variations in the relationship and influence of individual symptoms suggests that the functional and "communicative" role of individual symptoms may be differentiated by context specific imperatives.

BACKGROUND: Very little is known about the outcomes of poststroke delirium in relation to its symptom spectrum. We investigated the 3-months cognitive and functional outcomes of attenuated (ADS) and full delirium syndromes in Nigerian survivors of first ever stroke. METHODS: A prospective observational study with repeated assessments conducted in the first week of stroke using the confusion assessment method. Full delirium was diagnosed according to criteria in the fifth edition of the diagnostic and statistical manual of mental disorders (DSM-V). ADS was characterised in survivors who were free of full, but had ≥two core features of, delirium. Baseline and follow-up assessments were conducted using the Mini-Mental state examination (MMSE), 10-words list learning and delayed recall test, Animal naming test and Barthel index. RESULTS: Among 150 participants, ADS was present in 32 (21.3%), full delirium in 29 (19.3%). In linear regression analyses adjusting for age, economic status and systemic hypertension, ADS [(Mean difference (MD)â¯=â¯-3.8, 95% C.Iâ¯=â¯-7.0, -0.7)] and full delirium (MDâ¯=â¯-5.6, 95% C.Iâ¯=â¯-9.0, -2.1) independently predicted poorer global cognitive functioning at follow-up. Significant declines in memory (MDâ¯=â¯-1.9, 95% C.Iâ¯=â¯-2.8, 0.9), executive (MDâ¯=â¯-2.2, 95% C.Iâ¯=â¯-4.1, -0.3) and physical functioning (MDâ¯=â¯-2.8, 95% C.Iâ¯=â¯-5.5, -0.2), as well as a 4-fold increase in the independent odds (O.R) for dementia (O.Râ¯=â¯4.1, 95% C.Iâ¯=â¯1.0,16.1) were also recorded in full, but not attenuated, delirium. CONCLUSION: Attenuated and full delirium are associated with graded risk of poststroke cognitive decline. Reconsideration of poststroke delirium as a spectrum, rather than threshold-based categorical diagnosis will improve detection and prioritization of stroke survivors at increased risk of cognitive decline.

BACKGROUND: Contextually appropriate interventions delivered by primary maternal care providers (PMCPs) might be effective in reducing the treatment gap for perinatal depression. AIM: To compare high-intensity treatment (HIT) with low-intensity treatment (LIT) for perinatal depression. METHOD: Cluster randomised clinical trial, conducted in Ibadan, Nigeria between 18 June 2013 and 11 December 2015 in 29 maternal care clinics allocated by computed-generated random sequence (15 HIT; 14 LIT). Interventions were delivered individually to antenatal women with DSM-IV (1994) major depression by trained PMCPs. LIT consisted of the basic psychosocial treatment specifications in the World Health Organization Mental Health Gap Action Programme - Intervention Guide. HIT comprised LIT plus eight weekly problem-solving therapy sessions with possible additional sessions determined by scores on the Edinburgh Postnatal Depression Scale (EPDS). The primary outcome was remission of depression at 6 months postpartum (EPDS < 6). RESULTS: There were 686 participants; 452 and 234 in HIT and LIT arms, respectively, with both groups similar at baseline. Follow-up assessments, completed on 85%, showed remission rates of 70% with HIT and 66% with LIT: risk difference 4% (95% CI -4.1%, 12.0%), adjusted odds ratio 1.12 (95% CI 0.73, 1.72). HIT was more effective for severe depression (odds ratio 2.29; 95% CI 1.01, 5.20; P = 0.047) and resulted in a higher rate of exclusive breastfeeding. Infant outcomes, cost-effectiveness and adverse events were similar. CONCLUSIONS: Except among severely depressed perinatal women, we found no strong evidence to recommend high-intensity in preference to low-intensity psychological intervention in routine primary maternal care.
