    Abstract Study objectives: This study aimed to determine the sleep quality of in-school Nigerian adolescents and its association with their schooling and mental health outcomes.
    Methods: The study was a descriptive cross-sectional study. It was conducted among adolescents attending public and private secondary schools within the Ife Central Local Government, Osun State, southwestern Nigeria. A multistage sampling technique was used to select study participants. The Pittsburgh Sleep Quality Index, 9-item Patient Health Questionnaire (PHQ-9), and 7-item General Anxiety Disorder questionnaires were used to determine sleep quality, depression, and anxiety, respectively.
    Results: We studied 448 adolescents aged between 10 and 19 years with a mean age of 15.0 ± 1.8 years. The majority of our respondents (85.0%) had poor sleep quality. More than half of the respondents (55.1%) had insufficient sleep during weekdays, while only 34.8% had insufficient sleep during weekends. The school closing time and school type showed a statistically significant association with sleep quality (
    Conclusions: Sleep quality is poor in adolescents and adversely associated with their mental health. This should also be addressed in the development of appropriate interventions.

    Abstract Objectives In this study, the performance of OpenBCI, a low-cost bio-amplifier, is assessed when used for 3D motion reconstruction. Methods Eleven scalp electrode locations from three subjects were used, with sampling rate of 125 Hz, subsequently band-pass filtered from 0.5 to 40 Hz. After segmentation into epochs, information-rich frequency ranges were determined using filter bank common spatial filter. Simultaneously, the actual hand motions of subjects were captured using a Microsoft Kinect sensor. Multimodal data streams were synchronized using the lab streaming layer (LSL) application. A modified version of an existing multiple linear regression models was employed to learn the relationship between the electroencephalography (EEG) feature input and the recorded kinematic data. To assess system performance with limited data, 10-fold cross validation was used. Results The most information-rich frequency bands for subjects were found to be in the ranges of 5 - 9 Hz and 33 - 37 Hz. Hand lateralization accuracy for the three subjects were 97.4, 78.7 and 96.9% respectively. 3D position reconstructed with an average correlation coefficient of 0.21, 0.47 and 0.38 respectively along three pre-defined axes, with the corresponding average correlation coefficients for velocity being 0.21, 0.36 and 0.25 respectively. The results compare favourably with a cross-section of existing results, while cost-per-electrode costs were 76% lower than the average per-electrode cost for similar systems and 44% lower than the cheapest previously-reported system. Conclusions This study has shown that low-cost bio-amplifiers such as the OpenBCI can be used for 3D motion reconstruction tasks.

    Abstract Background: Stroke education in adolescents has been established as an effective method of creating awareness about stroke, its warning signs and risk factors. It contributes to desired behavioural change in the adolescents as well as their parents. Thus, we aimed to determine the baseline knowledge of school attending adolescents about stroke and its risk factors as well as the effect of stroke education on their stroke awareness.
    Methods: This study employed a quasi-experimental study design and was conducted in secondary schools in Ile-Ife, Osun State, Nigeria. The schools were divided into intervention and control groups. We assessed the baseline knowledge of the students on stroke, its risk factors, warning signs, and ways of preventing it using a pre-tested structured questionnaire in both intervention and control groups. In the intervention group, health talks on stroke consisting of oral presentation and distribution of fliers were presented for 30 minutes in each selected school. Each school was visited 2 weeks after the health education intervention to assess their knowledge on stroke, its risk factors, and ways of preventing it. The control group was also visited after 2 weeks for a re-assessment of their stroke knowledge and the conduct of heath talk on other aspects of neurology such as sleep, epilepsy, etc. Results: A total of 1259 adolescents were studied with 661 in the intervention group and 598 in the control group. The mean age of the respondents was 13.56 ± 2.87 the intervention group and 13.38 ± 2.06 in the control group. There were higher mean scores on knowledge of stroke and its risk factors among the intervention group than seen in the control group after the stroke education.
    Conclusions: Stroke education is an effective way of creating and maintaining stroke awareness among school-attending adolescents.

    Abstract The majority of neurological disorders exist in low- and middle-income countries, but these nations have the fewest neurologists and neurological training opportunities worldwide. The objective of this study was to assess the effectiveness, relevance, and feasibility of a five-day neurocritical care course delivered online to African healthcare workers and to understand participants' prior neurological and neurocritical care training experiences. We offered the Neurocritical Care Society's Emergency Neurological Life Support (ENLS) course covering 14 neurocritical conditions via Zoom to 403 African healthcare workers over a 4-day period. An additional day was devoted to management of neurological emergencies in resource-limited settings. Participants completed pre- and post-course surveys to assess the effectiveness, relevance, and feasibility of the overall course to their settings. 318 participants (46% female; 56% residents; 24% neurologists; 9.0 ± 6.7 years practicing medicine) from 11 African countries completed the pre-course self-assessment, and 232 completed the post-course self-assessment. 97% reported prior experience caring for patients with neurological emergencies but only 35% reported prior neurology training and 9% prior neurocritical care training. Pre-course and post-course comfort levels showed statistically significant improvements (p < 0.001) across all fourteen neurocritical topics. 95% of participants found the course relevant to their current practice setting, 94% agreed the Zoom online platform was easy to use, and 93% reported it facilitated their learning. Suggestions for course improvement included addition of non-critical neurological conditions and inclusion of locally available diagnostics and treatment modalities. Study results suggest virtual platforms may offer a way to improve neurology training in areas with reduced neurological workforce.

    Abstract Acute neurologic illnesses (ANI) contribute significantly to the global burden of disease and cause disproportionate death and disability in low-income and middle-income countries (LMICs) where neurocritical care resources and expertise are limited. Shifting epidemiologic trends in recent decades have increased the worldwide burden of noncommunicable diseases, including cerebrovascular disease and traumatic brain injury, which coexist in many LMICs with a persistently high burden of central nervous system infections such as tuberculosis, neurocysticercosis, and HIV-related opportunistic infections and complications. In the face of this heavy disease burden, many resource-limited countries lack the infrastructure to provide adequate care for patients with ANI. Major gaps exist between wealthy and poor countries in access to essential resources such as intensive care unit beds, neuroimaging, clinical laboratories, neurosurgical capacity, and medications for managing complex neurologic emergencies. Moreover, many resource-limited countries face critical shortages in health care workers trained to manage neurologic emergencies, with subspecialized neurocritical care expertise largely absent outside of high-income countries. Numerous opportunities exist to overcome these challenges through capacity-building efforts that improve outcomes for patients with ANI in resource-limited countries. These include research on needs and best practices for ANI management in LMICs, developing systems for effective triage, education and training to expand the neurology workforce, and supporting increased collaboration and data sharing among LMIC health care workers and systems. The success of these efforts in curbing the disproportionate and rising impact of ANI in LMICs will depend on the coordinated engagement of the global neurocritical care community.

    Abstract The burden of Parkinson's disease (PD) is becoming increasingly important in the context of an aging African population. Although PD has been extensively investigated with respect to its environmental and genetic etiology in various populations across the globe, studies on the African continent remain limited. In this Perspective article, we review some of the obstacles that are limiting research and creating barriers for future studies. We summarize what research is being done in four sub-Saharan countries and what the key elements are that are needed to take research to the next level. We note that there is large variation in neurological and genetic research capacity across the continent, and many opportunities for unexplored areas in African PD research. Only a handful of countries possess appropriate infrastructure and personnel, whereas the majority have yet to develop such capacity. Resource-constrained environments strongly determines the possibilities of performing research locally, and unidirectional export of biological samples and genetic data remains a concern. Local-regional partnerships, in collaboration with global PD consortia, should form an ethically appropriate solution, which will lead to a reduction in inequality and promote capacity building on the African continent.

    Abstract Purpose: Post-stroke arthritic changes that may compromise rehabilitation have been described in the upper and lower limbs. We aimed at evaluating the soft tissue arthritic changes associated with pain in hemiplegic knees of stroke patients in our environment.
    Material and methods: Hemiplegic and non-hemiplegic knees of 48 stroke patients as well as both knees of 26 apparently healthy controls were evaluated with a 7.5-12 MHz linear ultrasound probe. History of knee pain, and socio-demographic, laboratory, and clinical data were recorded for all study participants. Muscle tone and power as well as functional ambulatory category (FAC) were graded for the stroke patients. Data was analysed using SPSS version 20.
    Results: Pain was reported more often in hemiplegic than non-hemiplegic knees (
    Conclusions: Soft tissue arthritic changes associated with knee pain are comparable between hemiplegic and non-hemiplegic knees of stroke patients. The risk of knee pain in stroke is higher in the presence of pes anserinus tendinosis.

    Abstract Objectives: To determine the sleep pattern among Nigerian school-attending adolescents and its association with socioenvironmental factors and the use of electronic devices.
    Design: Descriptive cross-sectional survey.
    Setting: Public and private secondary schools in Ile-Ife, Osun State, Nigeria.
    Participants: Multistage sampling technique was used to select 346 school-attending adolescents aged 10-19 years.
    Measurements: A modified version of the Adolescent Sleep Habits Survey Questionnaire was administered to respondents in the school setting using the facilitated self-administration method.
    Results: Participants' mean age was 13.5±2.29 years, and the male-female ratio was 1:1.1. The mean total sleep duration on weekends of 9 hours (h) 08 minutes (min) ± 113 min was significantly higher than that of weekdays (7 h 15 min ± 86 min) (P < .001). About half of the respondents (48.7 %) had access to a computer. Majority of the respondents (80.9%) use one or more electronic device at bedtime, although cell phone was used by more than half (52.3%) of the respondents at bedtime. The proportion of adolescents with short sleep duration was 44.4% for weekdays and 5.5% for weekends. Lower social class and non-use of computers in the night time were independent predictors of adequate sleep duration on weekdays, whereas female sex, age (early adolescence), and polygamous family setting were independent predictors of sufficient sleep on weekends.
    Conclusion: A high proportion of school-attending adolescents have insufficient sleep on weekdays and significantly sleep less during weekdays compared to weekends. There is a need to target adolescents, parents, and school authorities with education on sleep issues.

    Abstract None: Interest in sleep and sleep disorders in Africa dates back thousands of years, influenced by various cultural and religious beliefs. However, the practice of sleep medicine as a specialty has been inadequate compared to other regions of the world. The objective of this study was to explore the current status of sleep medicine in Africa vis-à-vis education, professional societies, and facilities, and to identify challenges of the specialty in the region. A literature search of major electronic databases (PubMed, Google Scholar) was done. This revealed that there is a high prevalence of sleep disorders in Africa and a significant association with epilepsy, human African trypanosomiasis, human immunodeficiency virus, and other diseases. There are 6 sleep societies in Africa located in 4 countries. Forty-one sleep laboratories were identified located in 4 countries. The challenges hindering development of sleep medicine in Africa include lack of awareness, poor funding, lack of facilities, and inadequate training.
