Abstract
Alzheimer's disease (AD) and other dementias are a global challenge. Early diagnosis is important to manage the disease. However, there are barriers to diagnosis that differ by region. Researchers from Brazil, China, Nigeria, Spain, and Sweden have identified key barriers to AD diagnosis in their countries. In Brazil, socioeconomic inequalities and poor recognition of dementia by physicians can prevent diagnosis. In China, a very large population and lack of physician training in dementia make diagnosis problematic. In Nigeria, socioeconomic inequalities and cultural stigma can stand in the way of diagnosis. In Spain, patient hesitancy and an overloaded health-care system are barriers to diagnosis. In Sweden, inconsistent use of biomarkers is a prominent barrier to diagnosis of AD. To support diagnosis, more focus is needed on education of patients and physicians, increased use of support services, and improved access to biomarkers to accurately diagnose AD.

Abstract
INTRODUCTION The increasing burden of self-limiting forms of HIV-associated neurocognitive disorder (HAND) in the antiretroviral therapy era calls for adjunctive interventions. The study aimed to determine the effects of a 12-week aerobic exercise programme on HAND. METHODS This is a parallel-group, randomized controlled trial with concealed allocation and intention-to-treat analysis. This study was a clinic-based programme. Seventy-three patients with HAND were enrolled in the trial. The intervention comprised a moderate-intensity aerobic exercise, 20-60 min per session, three times per week, for twelve weeks. The control group received exercise education. Prevalence of HAND constituted the primary outcome. HAND was identified and classified following the Frascati criteria. We computed the odds ratio and number needed-to-treat to estimate the treatment effect. RESULTS There were 73 patients (38 in exercise and 35 in control arm). Individuals in the exercise arm recorded a significantly higher reduction in working memory deficit (OR = 5.14; CI = 2.6-10.4; NNT = 6) but not in attention-deficit (OR = 0.31, CI = 0.2-0.5; NNT = -5) compared to the control group at twelve-week. Reductions in attention deficit (OR = 1.55, 95 CI = 1.0-2.4; NNT = 5) and HAND prevalence (OR = 1.8, 95 CI = 1.2-2.8); NNT = 8) were significantly higher in the exercise group compared the control group at three-month. No significant between-group difference in functional independence was observed immediately after exercise (p > 0.05). DISCUSSION The neuroprotective effects of aerobic exercise appear selective and vary with cognitive abilities impaired and aerobic capacity, with a greater change occurring with improved aerobic capacity. CONCLUSION Individuals with working memory and attention deficits may benefit more from moderate-intensity aerobic exercise.

Abstract
BACKGROUND The study aimed to derive socio-demographic-corrected norms for selecting neuropsychological (NP) battery tests for people living with HIV (PLWHIV) in Nigeria. This cross-sectional study was conducted amongst patients who attended the general outpatient clinic and junior staff of the University of Nigeria Teaching Hospital (UNTH), Ituku-Ozalla. AIMS AND OBJECTIVES To determine the normative scores for select neuropsychological battery test for the detection of neurocognitive disorder amongst Nigerians PLWHIV. A sample of 92 individuals received voluntary HIV testing. METHODS Eligibility criteria were being HIV negative, aged 18-64 years and formal education. We undertook a brief neuromedical examination to identify putative exclusion criteria. We sampled four NP tests covering seven cognitive domains and the motor speed component of the International HIV Dementia Scale (IHDS-MS). We presented the normative scores using statistics of mean, median, standard deviation (SD), kurtosis and skewness. RESULTS All the participants were Nigerians aged 18-64 years. Most (74.1%) of the participants were females. The mean and median ages of the participants were 42.6 ± 11.42 years and 44 years, respectively. The effect of gender on NP performance was limited to the digit span test (DST)-forwards, while education affected all expect IHDS-MS and DST-backwards. The cut-off scores for defining mild and severe impairment varied (moving from 1SD to 2SD) for all cognitive domains except for IHDS-MS and DST. CONCLUSIONS With these preliminary normative scores, it will be easier to identify and classify the severity of neurocognitive impairment amongst PLWHIV in Nigeria, thus facilitating the goal of keeping HIV-associated dementia to a minimum. The lack of variability in the IHDS-MS and DST is unfavourable.

Abstract
African descent populations have a lower Alzheimer disease risk from ApoE ε4 compared to other populations. Ancestry analysis showed that the difference in risk between African and European populations lies in the ancestral genomic background surrounding the ApoE locus (local ancestry). Identifying the mechanism(s) of this protection could lead to greater insight into the etiology of Alzheimer disease and more personalized therapeutic intervention. Our objective is to follow up the local ancestry finding and identify the genetic variants that drive this risk difference and result in a lower risk for developing Alzheimer disease in African ancestry populations. We performed association analyses using a logistic regression model with the ApoE ε4 allele as an interaction term and adjusted for genome-wide ancestry, age, and sex. Discovery analysis included imputed SNP data of 1,850 Alzheimer disease and 4,331 cognitively intact African American individuals. We performed replication analyses on 63 whole genome sequenced Alzheimer disease and 648 cognitively intact Ibadan individuals. Additionally, we reproduced results using whole-genome sequencing of 273 Alzheimer disease and 275 cognitively intact admixed Puerto Rican individuals. A further comparison was done with SNP imputation from an additional 8,463 Alzheimer disease and 11,365 cognitively intact non-Hispanic White individuals. We identified a significant interaction between the ApoE ε4 allele and the SNP rs10423769_A allele, (β = -0.54,SE = 0.12,p-value = 7.50x10-6) in the discovery data set, and replicated this finding in Ibadan (β = -1.32,SE = 0.52,p-value = 1.15x10-2) and Puerto Rican (β = -1.27,SE = 0.64,p-value = 4.91x10-2) individuals. The non-Hispanic Whites analyses showed an interaction trending in the "protective" direction but failing to pass a 0.05 significance threshold (β = -1.51,SE = 0.84,p-value = 7.26x10-2). The presence of the rs10423769_A allele reduces the odds ratio for Alzheimer disease risk from 7.2 for ApoE ε4/ε4 carriers lacking the A allele to 2.1 for ApoE ε4/ε4 carriers with at least one A allele. This locus is located approximately 2 mB upstream of the ApoE locus, in a large cluster of pregnancy specific beta-1 glycoproteins on chromosome 19 and lies within a long noncoding RNA, ENSG00000282943. This study identified a new African-ancestry specific locus that reduces the risk effect of ApoE ε4 for developing Alzheimer disease. The mechanism of the interaction with ApoEε4 is not known but suggests a novel mechanism for reducing the risk for ε4 carriers opening the possibility for potential ancestry-specific therapeutic intervention.

Abstract
Background and Purpose The association of dyslipidemia with stroke has been inconsistent, which may be due to differing associations within etiological stroke subtypes. We sought to determine the association of lipoproteins and apolipoproteins within stroke subtypes.Methods Standardized incident case-control STROKE study in 32 countries. Cases were patients with acute hospitalized first stroke, and matched by age, sex and site to controls. Concentrations of total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A1 (apoA1), and apoB were measured. Non-HDL-C was calculated. We estimated multivariable odds ratio (OR) and population attributable risk percentage (PAR%). Outcome measures were all stroke, ischemic stroke (and subtypes), and intracerebral hemorrhage (ICH).Results Our analysis included 11,898 matched case-control pairs; 77.3% with ischemic stroke and 22.7% with ICH. Increasing apoB (OR, 1.10; 95% confidence interval [CI], 1.06 to 1.14 per standard deviation [SD]) and LDL-C (OR, 1.06; 95% CI, 1.02 to 1.10 per SD) were associated with an increase in risk of ischemic stroke, but a reduced risk of ICH. Increased apoB was significantly associated with large vessel stroke (PAR 13.4%; 95% CI, 5.6 to 28.4) and stroke of undetermined cause. Higher HDL-C (OR, 0.75; 95% CI, 0.72 to 0.78 per SD) and apoA1 (OR, 0.63; 95% CI, 0.61 to 0.66 per SD) were associated with ischemic stroke (and subtypes). While increasing HDL-C was associated with an increased risk of ICH (OR, 1.20; 95% CI, 1.14 to 1.27 per SD), apoA1 was associated with a reduced risk (OR, 0.80; 95% CI, 0.75 to 0.85 per SD). ApoB/A1 (OR, 1.38; 95% CI, 1.32 to 1.44 per SD) had a stronger magnitude of association than the ratio of LDL-C/HDL-C (OR, 1.26; 95% CI, 1.21 to 1.31 per SD) with ischemic stroke (<i>P</i><0.0001). Conclusions The pattern and magnitude of association of lipoproteins and apolipoproteins with stroke varies by etiological stroke subtype. While the directions of association for LDL, HDL, and apoB were opposing for ischemic stroke and ICH, apoA1 was associated with a reduction in both ischemic stroke and ICH. The ratio of apoB/A1 was the best lipid predictor of ischemic stroke risk.

Abstract
BACKGROUND HIV-associated neurocognitive disorder (HAND) negatively impacts quality of life (QoL) of people living with HIV who are on antiretroviral therapy (ART). Behavioural intervention adjunct to ART may improve QoL of people with HAND. We determine the effect of a 12-week aerobic exercise programme on QoL in people with HAND who were receiving ART. TRIAL DESIGN This was a parallel-group, randomised controlled trial with concealed allocation and intention-to-treat analysis. METHODS We identified 73 participants diagnosed with HAND. Participants were sampled from an earlier study that examined the prevalence of HAND according to the Frascati criteria. Participants were randomised and allocated to an intervention of 12-weeks of aerobic exercise, comprising three 20-60 min sessions per week of moderate-intensity aerobic exercise using a cycle ergometer. The primary outcome was QoL, which was evaluated using the World Health Quality of Life Questionnaire (WHOQoL)-BREF. RESULTS Participants in the exercise (n = 39) and control (n = 35) groups had similar sociodemographic characteristics (p > 0.05). Following the 12-week aerobic exercise programme, participants in the exercise group had improved physical (p < 0.001), psychological (p = 0.008) and environmental (p = 0.001) domains of the QoL (p = 0.001) and overall QoL (p = 0.001) relative to the control group. Similarly, participants in the exercise group had lower depression scores than participants in the control group. Depression scores in the exercise group were still lower 3 months post-intervention (p = 0.007). Only the improvements in physical (p = 0.02) and psychological (p = 0.007) domains of QoL were sustained at 3 months post-intervention. CONCLUSIONS Aerobic exercise improves the QoL of people with HAND. To ensure sustained benefits, people with HAND may need to engage in long-term physical exercise. Trial registration The trial is registered with the PAN African Trial Registry (PACTR). Date: 01/09/2020, ID: PACTR202009483415745.

Abstract
In tandem with the ever-increasing aging population in low and middle-income countries, the burden of dementia is rising on the African continent. Dementia prevalence varies from 2.3% to 20.0% and incidence rates are 13.3 per 1000 person-years with increasing mortality in parts of rapidly transforming Africa. Differences in nutrition, cardiovascular factors, comorbidities, infections, mortality, and detection likely contribute to lower incidence. Alzheimer's disease, vascular dementia, and human immunodeficiency virus/acquired immunodeficiency syndrome-associated neurocognitive disorders are the most common dementia subtypes. Comprehensive longitudinal studies with robust methodology and regional coverage would provide more reliable information. The apolipoprotein E (APOE) ε4 allele is most studied but has shown differential effects within African ancestry compared to Caucasian. More candidate gene and genome-wide association studies are needed to relate to dementia phenotypes. Validated culture-sensitive cognitive tools not influenced by education and language differences are critically needed for implementation across multidisciplinary groupings such as the proposed African Dementia Consortium.

Abstract
Background Since the introduction of antiretroviral therapy (ART), the incidence of HIV-associated dementia has drastically fallen. Despite using ART, people living with HIV continue to experience less severe but limiting forms of HIV-associated neurocognitive disorder (HAND). People living with HIV who are on ART and experiencing symptoms of HAND may benefit from aerobic exercise. Objective This protocol describes a randomized controlled trial designed to determine the effects of a 12-week aerobic exercise program on HAND in Southeastern Nigeria. Methods At least 68 patients diagnosed with HAND will be randomly placed into either an aerobic exercise group or control group. Patients in the aerobic exercise group will perform a moderate intensity workout on a stationary bicycle ergometer, 3 times a week for 12 weeks. We will measure the primary outcomes including neurocognitive performance, prevalence of HAND, viral load, and CD4 count. We will evaluate postexercise neurocognitive performance using reliable neuropsychological tests relevant to people living with HIV, in line with the Frascati criteria. We will assess secondary outcomes such as quality of life, activity limitation, and social participation using the World Health Organization Quality of Life (WHOQOL)-Brief, and the Oxford Participation and Activities questionnaire. We will use exploratory statistics to test the data for normality and homogeneity. We will analyze the effect of the exercise program on HAND using relative risk (RR) and absolute risk reduction (number needed to treat). Analysis of covariance will be run to estimate the effect of exercise on quality of life and activity and participation level. Results This funded trial was approved by the Institutional Review Board in May 2020. The protocol was approved on June 15, 2020. Enrollment commenced in January 2021 and was completed in May 2021. Over 60% of the participants were recruited at the time of first submission to JMIR Mental Health. Data curation is still ongoing; hence, data analysis is yet to be executed. Study outcomes are expected to be published in March 2022. Conclusions This is a protocol for a randomized controlled trial that aims to evaluate the effect of a 12-week aerobic exercise program on HAND in Southeastern Nigeria.

Abstract
BACKGROUND The increasing awareness and diagnosis of dementia in Africa necessitate documentation of caregiving practices to understand local patterns and improve the quality of care. Caregiving in African communities is rooted in informal-communal social organization. This scoping review analyses caregiver characteristics and experiences, and practices of caregiving for persons living with dementia in Africa. METHODS A total of 152 references were retrieved, with 64 references obtained from PubMed, 85 from AJOL, and three from Scopus. Based on the relevance of titles, 83 references were further retained from PubMed (64), AJOL (16), and Scopus (3). A rapid review of abstracts was done in Distiller SR, and finally, six relevant articles were content-analyzed using Atlas ti 8.4 qualitative analysis software. RESULTS All six included studies were published between 2003 and 2018. Four themes were identified: article characteristics, caregiver characteristics, caregiver in context, and caregiver potentialities (challenges and opportunities). Studies reported findings from research conducted in four African countries: three from Nigeria, and one each from South Africa, Egypt, and Tanzania. Caregivers of persons living with dementia typically had eight years or less of formal education, were unpaid, and spent a daily average of 13 hours in caregiving. Cultural thresholds and individual caregiver differences underlie the interpretation of stressors across cultures. Caregivers lack the right training and information as well as support systems to improve their role performance and reduce accumulated stress. CONCLUSION In African countries, informational and educational platforms are essential for improved individual dementia caregiving, vis-à-vis strengthened roles of governments, and religious/traditional leaders and organizations.

Gene-educational attainment interactions in a multi-ancestry genome-wide meta-analysis identify novel blood pressure loci. Mol Psychiatry 2021; 26:2111-2125.

Abstract
Educational attainment is widely used as a surrogate for socioeconomic status (SES). Low SES is a risk factor for hypertension and high blood pressure (BP). To identify novel BP loci, we performed multi-ancestry meta-analyses accounting for gene-educational attainment interactions using two variables, "Some College" (yes/no) and "Graduated College" (yes/no). Interactions were evaluated using both a 1 degree of freedom (DF) interaction term and a 2DF joint test of genetic and interaction effects. Analyses were performed for systolic BP, diastolic BP, mean arterial pressure, and pulse pressure. We pursued genome-wide interrogation in Stage 1 studies (N = 117 438) and follow-up on promising variants in Stage 2 studies (N = 293 787) in five ancestry groups. Through combined meta-analyses of Stages 1 and 2, we identified 84 known and 18 novel BP loci at genome-wide significance level (P < 5 × 10-8). Two novel loci were identified based on the 1DF test of interaction with educational attainment, while the remaining 16 loci were identified through the 2DF joint test of genetic and interaction effects. Ten novel loci were identified in individuals of African ancestry. Several novel loci show strong biological plausibility since they involve physiologic systems implicated in BP regulation. They include genes involved in the central nervous system-adrenal signaling axis (ZDHHC17, CADPS, PIK3C2G), vascular structure and function (GNB3, CDON), and renal function (HAS2 and HAS2-AS1, SLIT3). Collectively, these findings suggest a role of educational attainment or SES in further dissection of the genetic architecture of BP.

Abstract
BACKGROUND Although low sodium intake (<2 g/day) and high potassium intake (>3.5 g/day) are proposed as public health interventions to reduce stroke risk, there is uncertainty about the benefit and feasibility of this combined recommendation on prevention of stroke. METHODS We obtained random urine samples from 9,275 cases of acute first stroke and 9,726 matched controls from 27 countries and estimated the 24-hour sodium and potassium excretion, a surrogate for intake, using the Tanaka formula. Using multivariable conditional logistic regression, we determined the associations of estimated 24-hour urinary sodium and potassium excretion with stroke and its subtypes. RESULTS Compared with an estimated urinary sodium excretion of 2.8-3.5 g/day (reference), higher (>4.26 g/day) (odds ratio [OR] 1.81; 95% confidence interval [CI], 1.65-2.00) and lower (<2.8 g/day) sodium excretion (OR 1.39; 95% CI, 1.26-1.53) were significantly associated with increased risk of stroke. The stroke risk associated with the highest quartile of sodium intake (sodium excretion >4.26 g/day) was significantly greater (P < 0.001) for intracerebral hemorrhage (ICH) (OR 2.38; 95% CI, 1.93-2.92) than for ischemic stroke (OR 1.67; 95% CI, 1.50-1.87). Urinary potassium was inversely and linearly associated with risk of stroke, and stronger for ischemic stroke than ICH (P = 0.026). In an analysis of combined sodium and potassium excretion, the combination of high potassium intake (>1.58 g/day) and moderate sodium intake (2.8-3.5 g/day) was associated with the lowest risk of stroke. CONCLUSIONS The association of sodium intake and stroke is J-shaped, with high sodium intake a stronger risk factor for ICH than ischemic stroke. Our data suggest that moderate sodium intake-rather than low sodium intake-combined with high potassium intake may be associated with the lowest risk of stroke and expected to be a more feasible combined dietary target.

Abstract
Although many loci have been associated with height in European ancestry populations, very few have been identified in African ancestry individuals. Furthermore, many of the known loci have yet to be generalized to and fine-mapped within a large-scale African ancestry sample. We performed sex-combined and sex-stratified meta-analyses in up to 52,764 individuals with height and genome-wide genotyping data from the African Ancestry Anthropometry Genetics Consortium (AAAGC). We additionally combined our African ancestry meta-analysis results with published European genome-wide association study (GWAS) data. In the African ancestry analyses, we identified three novel loci (SLC4A3, NCOA2, ECD/FAM149B1) in sex-combined results and two loci (CRB1, KLF6) in women only. In the African plus European sex-combined GWAS, we identified an additional three novel loci (RCCD1, G6PC3, CEP95) which were equally driven by AAAGC and European results. Among 39 genome-wide significant signals at known loci, conditioning index SNPs from European studies identified 20 secondary signals. Two of the 20 new secondary signals and none of the 8 novel loci had minor allele frequencies (MAF) < 5%. Of 802 known European height signals, 643 displayed directionally consistent associations with height, of which 205 were nominally significant (p < 0.05) in the African ancestry sex-combined sample. Furthermore, 148 of 241 loci contained ≤20 variants in the credible sets that jointly account for 99% of the posterior probability of driving the associations. In summary, trans-ethnic meta-analyses revealed novel signals and further improved fine-mapping of putative causal variants in loci shared between African and European ancestry populations.

Abstract
BACKGROUND This study aims to identify the determinants of cognitive dysfunction and compare the effect of CPZ and LTC on cognition in WWE. METHODS An observational study involving 87 consenting adult WWE aged between 16 and 40 years on LTC or CZP monotherapy. At enrollment, an interviewer-based questionnaire was used to obtain demographic and clinical information from participants. The diagnosis of epilepsy was mainly clinical and supported by electroencephalographic (EEG) features and classified based on recommendation by the 2017 International League Against Epilepsy (ILAE). Zung Self-Reporting Depression Scale (ZSRDS) was used to assess the mood of participants. The Community Screening Interview for Dementia (CSID) was used to assess various cognition domains. The National Hospital Seizure Severity Scale (NHS-3) was used to assess disease severity. RESULTS There were statistical differences between the CZP and LTC groups in all domains of cognition assessed except for orientation. The total CSID scores of the LTC group were 59.2 (4.9) as opposed to CZP group, 57.2 (5.0); p: .005. Those with focal onset seizures had lower median total CSID score (58; IQR: 54-62) when compared to those with generalized onset seizures (62; IQR: 58-62), p: .012. There was a significant correlation between ZSRD score and NHS-3 score; rho: 0.30, p: .007. Bivariate analysis shows statistically significant correlation between total CSID score and ZSRDS (rho: -0.65), BMI (rho: 0.22), and NHSS-3 score (rho: -0.36), respectively. However, the effect of AED on CSID scores was lost after multivariate quantile regression with only ZSRDS retaining significance. CONCLUSION Depression, seizure severity, type and structural etiology were associated with cognitive impairment among WWE. However, on regression model, only depression was statistically significant. The presence of more risks for cognitive impairment in the CZP group limits possible conclusion of LTC superiority.

Abstract
OBJECTIVE The study is aimed at comparing effects of older drugs like carbamazepine (CBZ) and newer agent like levetiracetam (LEV) on polycystic ovarian syndrome (PCOS) in women with epilepsy (WWE). METHODS An interviewer-based questionnaire was used to obtain relevant clinical information from 50 WWE on CBZ and LEV monotherapy, respectively, and 50 age-matched controls. The diagnosis of epilepsy was clinical with electroencephalographic features taken into consideration and the seizures classified using the 2017 International League Against Epilepsy classification. The diagnosis of PCOS was based on the European Society for Human Reproduction and Embryology/American Society for Reproductive Medicine. RESULTS The frequency of PCOS and its subcomponent were higher among WWE compare to controls. PCOS was present in 22 (44%) of LEV group compare to 8 (16%) CBZ group. The frequency of its subcomponent was higher among those on LEV except for comparable effect with regard to oligomenorrhea. The levels of the sex steroid hormone were comparable in both groups of WWE except luteal phase luteinizing hormone, which was lower among the LEV group (P .001). The follicular phase estradiol level was lower (P .021), and follicle-stimulating hormone level was about 2-fold higher (P .03) among WWE compare to controls. The mean value testosterone was significantly lower among controls compared to WWE. CONCLUSIONS The increased frequency of PCOS and its subcomponent and the unsatisfactory effect of LEV compared to CBZ on reproductive endocrine function underscore the need for routine reproductive endocrine evaluation to improve overall quality of life.

Abstract
BACKGROUND Cardiac autonomic neuropathy (CAN) resulting from seizures has been implicated in sudden unexpected death in epilepsy in persons with epilepsy (PWE), however, there are no previous studies of CAN in PWE from Nigeria. OBJECTIVES This study sought to determine the frequency and pattern of CAN in adult PWE in a tertiary hospital in South-western Nigeria and to determine the relationship between seizure variables and CAN. METHODS A cross-sectional study of 80 adult PWE and 80 matched controls aged between 18 and 60 years was carried out between March 2012 and June 2013 at the Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria. Demographic and clinical data were obtained from all the study participants. Anxiety was excluded using the Hamilton Anxiety Scale. Those with conditions that could affect autonomic function, such as chronic renal failure, heart failure, Parkinson's disease, diabetes mellitus, anxiety, and psychiatric disorders and pregnant women were excluded. Five bedside cardiovascular reflex tests were performed on each subject after baseline heart rate and blood pressure (BP) had been recorded. RESULTS The mean age of onset of epilepsy was 19 ± 10 years, whereas the mean duration of epilepsy was 10 ± 8 years. The mean seizure frequency was 14 ± 30 per month (median three seizures per month). Of the 80 patients evaluated, 42 (52.5%) had CAN, whereas none of the controls had CAN. Majority (69%) of the PWE with CAN had purely parasympathetic dysfunction, whereas 3% had purely sympathetic dysfunction and 10% had combined autonomic dysfunction. The PWE in this study had significantly lower tilt ratios and diastolic BP change with Isometric Hand grip as well as significantly higher systolic BP change on standing than the controls. Patients who had more than four seizures per month had higher odds of CAN than those with less frequent seizures (odds ratio 0.275, P value 0.023). Also, patients who had received treatment for less than 10 years were found to have greater odds of CAN than those who had received treatment for a longer period (odds ratio 11.676, P value 0.046). CONCLUSION CAN is common in adult PWE in South-Western Nigeria and the major predictors are short duration of treatment and frequent seizure episodes. Routine screening of these patients may help with early detection of autonomic dysfunction and provide an opportunity for intervention.

Abstract
INTRODUCTION There is a growing global concern about the effect of epilepsy on the Health-Related Quality of Life (HRQoL) of the sufferers. AIM This study assessed the determinants of HRQoL in persons with epilepsy (PWE) in a tertiary hospital in North Western Nigeria. METHODOLOGY A cross-sectional study was carried out on 103 patients with epilepsy aged ≥ 18 years attending Neurology clinic. Ethical clearance was obtained from the Health Research Ethics Committee of the institution. The short version of the World Health Organization Quality of Life questionnaire (WHOQOL-BREF) was administered to the participants. Statistical significance was set with p value at 0.05. The determinants of HRQoL was obtained by using univariate and subsequent multivariate logistic regression analysis. RESULT The mean age of patients was 33.4±15.8 years. There were 54(52.4%) males and 49 (47.6%) females. The significant determinants of HRQoLfound were time of last seizure episode (OR = 7.50, 95% CI = 1.36 -41.20, p = 0.021) and social support (OR = 21.5, 95% CI = 3.67 - 125.68, p = 0.001). Following multivariate logistic regression analysis, social support (OR = 29.51, 95% CI = 2.87 - 302.66, p = 0.004) appeared as the independent determinant of HRQoLin PWE. CONCLUSION Social support was the main determining factor of HRQoL in epilepsy patients in this study. Therefore there is the need to ensure a comprehensive care which should include health education, adequate seizure control and social support for epilepsy patients to improve their HRQoL.

Abstract
Abstract
Background
Health care-associated infections (HAI) are one of the most common adverse events in care delivery and a major public health problem. A large percentage of HAI in hospitals are preventable through effective infection prevention and control (IPC) measures. IPC trainings for health care personnel based only on technical content do not lead to sustainable improvement of IPC standard precautions. To address this problem, the Nigeria Centre for Disease Control (NCDC) in collaboration with the Robert Koch Institute (RKI) developed a multimodal training approach to facilitate the transfer of IPC competences into working routine in Nigerian health facilities.
Objectives
The training should foster the ability of health care workers to act and communicate participatory, analyze IPC problems systemically and to develop and perform tailored IPC activities in their health facilities. It should empower health care workers to initiate and promote sustainable IPC improvement locally.
Results
We developed a participatory training approach which focusses on the relational and organizational dimension of IPC. It addresses the human and infrastructural factors for IPC compliance in daily working routine. A variety of training methods offers practice tools in communication, systemic thinking and team work, and allows experiencing a participatory attitude. The training program consists of two face to face workshops and an interjacent field project. 28 Health care workers of 14 health facilities in Lagos State participated the first implementation of the training program in 2018. The training evaluation showed the high relevance of the training to the HCW. The field projects showed that the participants could apply the participatory approach for IPC improvement.
Conclusions
A participatory and systemic approach for IPC trainings enables health care workers to take action for IPC improvement locally.
Key messages
We developed and implemented a participatory training approach that addresses the relational and organizational dimension of IPC. Health care workers took tailored actions for IPC improvement locally.

Abstract
BACKGROUND In the face of an emergency, a decision on the need for a timely intervention must be made urgently especially when it has to do with the brain. This study was conducted to determine the usefulness of Urine combistix and glucometer as a "point of care" testing tool in the emergency analysis of cerebrospinal fluid (CSF) in resource-limited settings. METHODOLOGY In this pilot cross-sectional study, CSF and blood glucose were simultaneously measured using a point of care glucometer and central laboratory. The CSF protein, glucose, blood and leucocytes were also assessed using the urine combistix strips. The CSF/blood glucose ratios obtained at the bedside with a glucometer versus those obtained by the central laboratory were also compared. RESULTS Turn-around time for glucometer and Combistix analysis was 3.5minutes (3-4mins) versus 360minutes (300- 600minutes) for the laboratory. A strong correlation was observed amongst urine Combistix values for CSF protein, blood, leucocyte and glucose with those obtained from the laboratory (ROC of 0.875, sensitivity:75% and specificity: 100%). In addition, there was significant correlation of the CSF-blood glucose ratios from both the laboratory versus glucometer. CONCLUSION This pilot study showed that a combination of Combistix analysis for CSF protein, glucose, blood and leucocyte values plus a glucometer analysis of CSF and blood glucose can serve as a reliable and accurate synergistic means for early diagnosis of CSF abnormalities particularly in patients suspected to have meningitis. Finally, it provides a template on which an accurate CSF diagnostic kit can be developed.
