Quality of life of stroke survivors in Africa: a systematic review and meta-analysis.

PURPOSE: Functional impairments and socioeconomic constraints associated with stroke affect quality of life (QoL). With limited care and social support resources, there is a greater anticipated decline in QoL among stroke survivors in Africa. This study aims to examine post-stroke QoL, properties of outcome measures adopted and predictors of the QoL among African stroke survivors. METHODS: African Journals Online, CINAHL, PsychINFO, PubMed and Web of Science databases were searched from inception to February 2020. Methodological quality was assessed using the Agency for Healthcare Research and Quality (ARHQ) methodology checklist for observational studies. RESULTS: Twenty-eight studies recruiting 2572 (76.4%) stroke survivors and 795 (23.6%) healthy volunteers were included. Studies were conducted in eight African countries between 2007 and 2019. Methodological quality of studies was good. Overall, stroke survivors reported a low QoL. Six studies comparing QoL between stroke survivors and healthy controls were pooled for meta-analysis. Results showed a biased-adjusted standardised mean difference (Hedges's g) of 1.13 (95% CI 0.71 to 1.56; p < 0.001), indicating better QoL among healthy controls. Only 4 (14.3%) studies used translated or cross-culturally adapted QoL assessment tools. The most commonly reported predictor of QoL was post-stroke disability (35.8% of studies) which is followed by depression (28.6%) and stroke severity (28.6%). CONCLUSIONS: Overall, African stroke survivors reported comparatively lower QoL as compared to age-matched healthy controls. This highlights the need for cross-culturally validated assessment tools and more robust post-stroke QoL evaluation across the African continent. To improve QoL of stroke survivors in Africa, early interventions should focus on reducing disability and depression associated with stroke. PROSPERO registration number: CRD42019137653.

The association between vertebral endplate structural defects and back pain: a systematic review and meta-analysis.

PURPOSE: To clarify the current state of knowledge on the association of endplate structural defects and back pain. METHODS: Five databases were searched for studies reporting on the association between endplate structural defects and back pain. Covidence and comprehensive meta-analysis software were used for article screening and selection and pooling of extracted data. Overall quality of evidence was assessed using GRADE. RESULTS: Twenty-six studies comprised of 11,027 subjects met inclusion criteria. The presence of moderate heterogeneity (I2 = 73%; p = 0.001) prevented the pooling of estimates across all studies. However, it was possible to pool studies of specific endplate defect phenotypes, such as erosion (OR: 2.69; 95% CI: 1.35-5.50) and sclerosis (OR: 1.97; 95% CI: 1.50-2.58), which yielded significant associations with back pain. Schmorl's nodes were also associated with most individual back pain phenotypes (OR: 1.53-1326, I2 = 0-7.5%) and back pain overall (OR: 1.63, 95% CI: 1.37-1.94, I2 = 26%) in general population samples. The pooling of data from all studies of specific back pain phenotypes, such as frequent back pain (OR: 2.83; 95% CI: 1.77-4.52) and back pain incidence (OR: 1.65; 95% CI: 1.30-2.10), each yielded significant association with endplate structural defects and was supported by low heterogeneity (I2 = < 7.5.%). CONCLUSION: Overall, there is moderate quality evidence of an association between back pain and endplate structural defects, which is most evident for erosion, sclerosis and Schmorl's nodes. Going forward, research on specific endplate defect phenotypes and back pain case definitions using strong study designs will be important in clarifying the extent of associations and underlying mechanisms. The study was prospectively registered in Prospero (CRD42020170835) on 02/24/2020.

Pattern and outcome of traumatic spinal cord injury managed at University of Maiduguri Teaching Hospital, Nigeria: A retrospective study.

BACKGROUND: Understanding pattern and outcome of traumatic spinal cord injury (TSCI) will inform better management which expectedly would improve prognosis and minimise complications. METHODS: : A retrospective study was carried out on all managed TSCI cases from January 2009 to December 2018. Sociodemographic characteristics, injury type, cause and complications were extracted from patients' registers and case folders. Descriptive statistics summarised the data, and Fisher's exact test analysed associations between variables. RESULTS: Eighty-one cases met the inclusion criteria and were analysed. Most cases (91.4%) were males, aged 18-39 years (65.4%) and were civil servants (37.0%). Road traffic accident (RTA) was the leading cause of injury (37.0%) and incomplete lesion predominated (69.1%). Cases referred for physiotherapy constituted 77.8%, only 14.8% of cases recovered without neurological deficits. On discharge, most patients were wheelchair bound (33.3%). Region of spine affected showed significant association with complications developed (P = 0.01). RTA caused more dead as a cause of injury was found to be significantly associated with outcome (P = 0.04). Referral for physiotherapy showed significant association with outcome (P = 0.01), so also, region of spine affected with outcome (0.01). The study found a significant association between type of injury and functional status (P = 0.01). CONCLUSIONS: : The study concludes that young adults of working class were mostly affected, and RTA and gunshots injuries were the leading causes of TSCI. Findings such as the association found between regions of spine affect and complication developed on admission will help healthcare providers identify those susceptible and offer prompt preventive measures.

Vertebral endplate defects: nomenclature, classification and measurement methods: a scoping review.

PURPOSE: To summarize the scope of nomenclature and measurement methods used to document endplate defects in the health sciences literature. METHODS: The scoping review followed the York framework and was reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews. The databases of PubMed, Scopus, Embase and CINAHL were searched using key terms. Screening and selection were conducted by two independent reviewers. A standardized, pilot-tested form was used for extracting data, which were analyzed descriptively. RESULTS: The review included 211 studies, originating from 29 countries, with the USA (18.8%) and China (12.26%) as leading contributors. Thirty-four different terms for structural endplate defects were reported, but were never defined in most studies (65%). Of the 34 different terms used, some appeared to represent the same phenomenon, while the same terms were occasionally defined differently between studies. Schmorl's nodes were most commonly investigated (n = 99 studies) and defined similarly across studies, with the main difference relating to whether the indentation (node) was required to have a sclerotic margin. There were also similarities in definitions for endplate sclerosis. However, there was great variability in the definitions of other terms, such as lesions, irregularities, abnormalities, erosions and changes. CONCLUSION: With the possible exception of Schmorl's nodes, we lack a common language for effectively communicating structural endplate findings. This review provides a foundation and impetus for standardizing terminology and core measures to improve communication and synthesis of the growing body of endplate research to advance related knowledge.

Relationship between Physical Activity and Health Related Quality of Life among Pregnant Women.

The study aimed to investigate the association between health-related quality of life (HQoL) and physical activity (PA) among pregnant women. Sample of pregnant women (N= 398; mean age=27.86±5.15 years) were surveyed using the Pregnancy Physical Activity and Health Related Quality of Life (SF 12) Questionnaires. Spearman correlation coefficient and logistic regression analyses were used to determine the bivariate relationship and association between HQoL and PA intensities and domain respectively. Overall, sedentary behaviour was positively albeit tenuously related to HQoL (r=0.111, P <0.01) whereas sport/exercise was the only domain of PA tenuously associated with the Physical health of HQoL (r=0.142, p <0.01). Also, pregnant women with sufficient PA were 4 times likely to report good quality of life in physical component not in the mental component of HQoL (OR: 4.33, 95% CI: 1.36-13.80). In conclusion, sports/exercise may be an important domain of PA to target when delivering interventions to improve the physical wellbeing among pregnant women in Maiduguri, Nigeria.

Detection and Characterization of Endplate Structural Defects on CT: A Diagnostic Accuracy Study.

STUDY DESIGN: Diagnostic test study. OBJECTIVE: To determine the reliability and validity or diagnostic accuracy of two previously described endplate structural defect (EPSD) assessment methods. SUMMARY OF BACKGROUND DATA: Studies of EPSD may further the understanding of pathoanatomical mechanisms underlying back pain. However, clinical imaging methods used to document EPSD have not been validated, leaving uncertainty about what the observations represent. METHODS: Using an evaluation manual, 418 endplates on CT sagittal slices obtained from 19 embalmed cadavers (9 men and 10 women, aged 62-91 y) were independently assessed by two experienced radiologists and a novice for EPSD using the two methods. The corresponding micro-CT (µCT) from the harvested T7-S1 spines were assessed by another independent rater with excellent intra-rater reliability (Kappa=0.96). RESULTS: Inter-rater reliability was good for presence (Kappa=0.60-0.69) and fair for specific phenotypes (Kappa=0.43-0.58) of EPSD. Erosion, for which the Brayda-Bruno classification lacked a category, was mainly (82.8%) classified as wavy/irregular, while many notched defects (n=15, 46.9%) and Schmorl's nodes (n=45, 79%) were recorded as focal defects using Feng's classification. When compared to µCT, endplate fractures (n=53) and corner defects (n=28) were routinely missed on CT. Endplates classified as wavy/irregular on CT corresponded to erosion (n=29, 21.2%), jagged defects (n=21, 15.3%), calcification (n=19, 13.9%), and other phenotypes on µCT. Some focal defects on CT represented endplate fractures (n=21, 27.6%) on µCT. Overall, with respect to the presence of an EPSD, there was a sensitivity of 70.9% and specificity of 79.1% using Feng's method, and 79.5% and 57.5% using Brayda-Bruno's. Poor to fair inter-rater reliability (k=0.26-0.47) was observed for defect dimensions. CONCLUSION: There was good inter-rater reliability and evidence of criterion validity supporting assessments of EPSD presence using both methods. However, neither method contained all needed EPSD phenotypes for optimal sensitivity, and specific phenotypes were often misclassified.

Clinicopathological pattern of oestrogen receptor, progesterone receptor and human epidermal growth factor receptor-2 over-expression of epithelial ovarian carcinomas in Nigeria.

Background: Ovarian cancer is the leading cause of death from all gynaecological malignancies. Only few biomarkers of epithelial ovarian cancer (EOC) prognosis have been studied so far among Nigerian patients. Objective: To determine the pattern of oestrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2) expression in patients with EOC seen in Nigeria. Materials and Methods: This was a retrospective multicentre study of 102 cases of epithelial ovarian cancers. Relevant clinical information was obtained from hospital-based records in the 3 participating centres. Tissue microarrays were constructed using representative tumour tissue and the ER, PR and HER2 immunohistochemical staining was carried out at the University of Chicago, United States of America. Results: Serous carcinomas predominated (71% of cases). ER positivity was observed in 31.4%, PR positivity in 21.5% and HER2/neu in 16.7% of tumours. Fifty-two percent of tumours were triple negative. Serous tumours were significantly associated with ER positivity (p=0.001). Mean patient age for EOC was 52.6 ± 13.1 years. There were no statistically significant associations between hormone receptor status and histological grade, FIGO staging or survival. Conclusion: Serous tumours were significantly associated with ER expression while non-serous tumours tended to be triple negative.

Prevalence of Anxiety and Depression Among the General Population in Africa During the COVID-19 Pandemic: A Systematic Review and Meta-Analysis.

Background: Medical and socio-economic uncertainties surrounding the COVID-19 pandemic have had a substantial impact on mental health. This study aimed to systematically review the existing literature reporting the prevalence of anxiety and depression among the general populace in Africa during the COVID-19 pandemic and examine associated risk factors. Methods: A systematic search of the following databases African Journal Online, CINAHL, PubMed, Scopus, and Web of Science was conducted from database inception until 30th September 2021. Studies reporting the prevalence of anxiety and/or depression among the general populace in African settings were considered for inclusion. The methodological quality of included studies was assessed using the Agency for Healthcare Research and Quality (AHRQ). Meta-analyses on prevalence rates were conducted using Comprehensive Meta-analysis software. Results: Seventy-eight primary studies (62,380 participants) were identified from 2,325 studies via electronic and manual searches. Pooled prevalence rates for anxiety (47%, 95% CI: 40-54%, I2 = 99.19%) and depression (48%, 95% CI: 39-57%, I2 = 99.45%) were reported across Africa during the COVID-19 pandemic. Sex (female) and history of existing medical/chronic conditions were identified as major risk factors for anxiety and depression. Conclusions: The evidence put forth in this synthesis demonstrates the substantial impact of the pandemic on the pervasiveness of these psychological symptoms among the general population. Governments and stakeholders across continental Africa should therefore prioritize the allocation of available resources to institute educational programs and other intervention strategies for preventing and ameliorating universal distress and promoting psychological wellbeing.

Impact of physical activity and traumatic exposure on occurrence of gestational hypertension: a survey of pregnant women in an armed-conflict region in Nigeria.

OBJECTIVE: To compare physical activity level and traumatic exposure between normotensive and hypertensive pregnant women in an armed conflict region of Nigeria. METHODS: 130 normotensives and hypertensive pregnant women comprising of 65 participants per group participated in the study. Harvard Trauma Questionnaire and Pregnancy Physical Activity Questionnaire were used to assess traumatic events and physical activity respectively. RESULTS: Significant difference was observed on total traumatic event (p = 0.008) and all domains and intensities of physical activity except inactivity and sedentary (p > 0.05). Household activities (OR: 0.989; 95% CI: 0.981-0.996), occupational activities (OR: 0.936; 95%CI: 0.879-0.996) and sport/exercise activities (OR: 0.898; 95%CI: 0.832-0.969) were associated with a decrease hypertensive pregnancy. CONCLUSION: Despite exposed to traumatic events, physical activity is associated with normotensive pregnancy in an armed conflict region.

Musculoskeletal Symptoms among Family Caregivers of Community-Dwelling Stroke Survivors in Nigeria.

Introduction: Caring for stroke survivors may be burdensome with adverse consequences on caregivers' physical health. This study examined the prevalence of musculoskeletal symptoms and associated factors among family caregivers of stroke survivors in Nigeria. Methods: A hospital-based cross-sectional study involving 90 stroke caregiver and stroke survivor dyads was conducted. Data on the participants' demographics and post-stroke duration were obtained. Seven-day prevalence of musculoskeletal symptoms among the caregivers and level of stroke survivors' disability were respectively assessed using the Nordic Musculoskeletal Questionnaire and Modified Rankin Scale. Prevalence of musculoskeletal symptoms was presented as percentages while participants' characteristics associated with prevalence of musculoskeletal symptoms were examined using inferential statistics. Results: Mean (SD) age of caregivers and stroke survivors was 33.2 (10.7) years and 58.9 (9.7) years respectively. Majority of the caregivers were females (61.1%), and children of the stroke survivors (58.9%). Prevalence of musculoskeletal symptoms was 82.2%. The low back was the most affected body region (72.2%) followed by the upper back (40%) while musculoskeletal symptoms in the wrist was least prevalent (3.3%). Female caregivers, caregivers of female stroke survivors and spousal caregivers had significantly higher prevalence of musculoskeletal symptoms compared to other categories of caregivers. Only 5 (5.6%) caregivers had however received any training on safe care giving methods while only 21 (28.4%) caregivers with musculoskeletal symptoms had received treatment. Conclusion: With the high prevalence of musculoskeletal symptoms among family caregivers of stroke survivors, effective preventive strategies including training and education as well as timely access to treatment would be required.

Physical activity profile of Nigeria: implications for research, surveillance and policy.

Appraising the status of physical activity surveillance, research and policy in Nigeria is relevant to national and regional public health actions on physical activity promotion and non-communicable disease control. This study aimed to 1) evaluate the physical activity profile of Nigeria and 2) propose strategies for improving physical activity in the country. The Global Observatory for Physical Activity-GoPA! with inputs from local experts systematically collected sociodemographic and physical activity surveillance, national policy and research indicators data for Nigeria in 2014. The Nigerian Country Card highlighting the status of these indicators was developed in 2015 and launched in 2016. Prevalence of physical activity among Nigerian adults was 78% (female=76%, male=79%). There was no physical activity surveillance system and national plan, and no empirical data on the proportion of all deaths directly due to physical inactivity in Nigeria. Few (n=7) articles related to physical activity and public health were published in 2013 and the country occupied the 38th position in the global research ranking, contributing about 0.24% to physical activity research worldwide. Implementing national physical activity plans and multi-sectorial collaborations between government and non-governmental partners are needed to improve physical activity surveillance, research and policy in Nigeria and other African countries with similar physical activity gaps.

Patterns and Associated Factors of Physical Activity among Adolescents in Nigeria.

INTRODUCTION: Understanding the context where adolescents' physical activity (PA) takes place could impact a more targeted approach to implement PA promotion and interventions in Africa. However, standardized data on adolescents' PA behaviour is lacking in Nigeria. We described PA patterns in the various domains (home, school, transport, leisure-time) and intensity categories (light-intensity PA, moderate- to vigorous- intensity physical activity [MVPA] and total PA), and their associations with sociodemographic factors and socioeconomic status (SES) among secondary school adolescents in Nigeria. METHODS: A cross-sectional survey was conducted in a representative sample of 1006 secondary school adolescents (12-18 years, 50.4% girls) in Maiduguri, Nigeria. Self-reported PA was assessed with an adapted version of the Activity Questionnaire for Adolescents and Young Adults. Outcomes were weekly minutes (min/wk) of PA spent in the various domains and intensity categories. Multivariate ANOVA was used to examine associations of PA scores (domains and intensity levels) with adolescents' sociodemographic characteristics and SES, and track differences in PA scores between subgroups. RESULTS: The total sample reported most PA at school (1525 min/wk), the least during active transportation (210 min/wk), and only 37% engaged in 60 min of MVPA daily. Boys reported significantly more leisure-time PA (P<0.001), active transportation (P<0.001), MVPA (P = 0.023) and total PA (P = 0.003) than girls, while girls reported more school-based PA (P = 0.009), home-based PA (P<0.001) and light-intensity PA (P<0.001) than boys. Moderate-intensity PA (P = 0.024) and total PA (P = 0.049) were significantly higher in younger age group than in older group. Household car ownership was associated with less active transportation (P = 0.009), less moderate-intensity PA (P = 0.048) and with more leisure-time PA (P = 0.013). High parental SES was associated with more leisure-time PA (P = 0.002), more MVPA (P = 0.047) and less active transportation (P<0.001). Adolescents of various weight status differed significantly in their leisure-time PA (P<0.001), moderate-intensity PA (P = 0.011) and total PA (P = 0.033). CONCLUSIONS: The patterns and levels of physical activity among adolescents in Nigeria vary according to the adolescents' age, gender, weight status and SES. These findings have important public health implications for identifying subgroups of Nigerian adolescents that should be targeted for effective physical activity promoting interventions.
