Diversity, equity, and inclusion: Findings from the Sleep Research Society.

Objectives: To characterize representation and inclusion among Sleep Research Society members and examine associations between sociodemographic features and Sleep Research Society experiences.

Methods: The Sleep Research Society Taskforce for Diversity and Inclusion developed a web-based questionnaire in 2021, assessing membership data and Sleep Research Society experiences (self-initiated and society-initiated participation, feeling very welcomed, perceptions of inclusiveness, and diversity of viewpoints represented). Frequencies were calculated and adjusted Poisson regression models with robust variance were fit to estimate associations.

Stroke occurrence by hypertension treatment status in Ghana and Nigeria: A case-control study.

Background: Hypertension is preeminent among the vascular risk factors for stroke occurrence. The wide gaps in awareness, detection, treatment, and control rates of hypertension are fueling an epidemic of stroke in sub-Saharan Africa.

Purpose: To quantify the contribution of untreated, treated but uncontrolled, and controlled hypertension to stroke occurrence in Ghana and Nigeria.

Challenges to Thrombolysis in A Resource-Poor Setting- A Case Report.

A major complication of acute ischemic stroke is death and disability. The emergence of reperfusion therapy in form of thrombolysis and endovascular thrombectomy has led to the reversal of this trend in high-income countries. Low- and middle-income countries are yet to benefit maximally from these time-bound treatment options due to some limitations.

Dietary patterns associated with hypertension among stroke-free indigenous Africans: insights from the Stroke Investigative Research and Educational Network study.

Background: The dietary factors associated with the high burden of hypertension among indigenous Africans remain poorly understood. We assessed the relationship between dietary patterns and hypertension among indigenous Africans.

Method: In this study, 1550 participants with hypertension matched (for age: ± 5 years, sex and ethnicity) with 1550 participants without hypertension were identified from the stroke-free population in the Stroke Investigative Research and Educational Network study in Ghana and Nigeria.

Factors associated with frequency of fruit and vegetable consumption among selected sub-Saharan African populations: evidence from the Cardiovascular H3Africa Innovation Resource Project.

Background: Frequent fruit and vegetable consumption is considered a promising dietary behaviour that protects health. However, most existing studies about the factors associated with this phenomenon among Africans are based on single-country reports, apart from one meta-regression combining smaller studies. This study harmonized large datasets and assessed factors associated with the frequency of fruit and vegetable consumption in this population.

Clinical and neuroimaging factors associated with 30-day fatality among indigenous West Africans with spontaneous intracerebral hemorrhage.

Background: Spontaneous intracerebral hemorrhage (ICH) is associated with a high case fatality rate in resource-limited settings. The independent predictors of poor outcome after ICH in sub-Saharan Africa remains to be characterized in large epidemiological studies. We aimed to determine factors associated with 30-day fatality among West African patients with ICH.

Risk Assessment Score and Chi-Square Automatic Interaction Detection Algorithm for Hypertension Among Africans: Models From the SIREN Study.

Background: This study aimed to develop a risk-scoring model for hypertension among Africans.

Methods: In this study, 4413 stroke-free controls were used to develop the risk-scoring model for hypertension. Logistic regression models were applied to 13 risk factors.

Identification of genetic risk loci and causal insights associated with Parkinson's disease in African and African admixed populations: a genome-wide association study.

Background: An understanding of the genetic mechanisms underlying diseases in ancestrally diverse populations is an important step towards development of targeted treatments. Research in African and African admixed populations can enable mapping of complex traits, because of their genetic diversity, extensive population substructure, and distinct linkage disequilibrium patterns. We aimed to do a comprehensive genome-wide assessment in African and African admixed individuals to better understand the genetic architecture of Parkinson's disease in these underserved populations.

MAPT allele and haplotype frequencies in Nigerian Africans: Population distribution and association with Parkinson's disease risk and age at onset.

Introduction: The association between MAPT and PD risk may be subject to ethnic variability even within populations of similar geographical origin. Data on MAPT haplotype frequencies, and its association with PD risk in black Africans are lacking. We aimed to determine the frequencies of MAPT haplotypes and their role as risk factors for PD and age at onset in Nigerians.

Sleep quality and its relationship with school schedules and mental health of Nigerian secondary school adolescents.

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.

Neurocritical Care in Nigeria.

Nigeria is the most populous country in Africa with an estimated 206 million inhabitants served by less than 300 neurologists and 131 neurosurgeons. Neurological conditions account for approximately 18% of all medical emergencies. Neurocritical care challenges in Nigeria are as complex as they are in other low-to-middle-income countries (LMICs).

allele and haplotype frequencies in Nigerian Africans: population distribution and association with Parkinson's disease risk and age at onset.

Background: The microtubule-associated protein tau ( ) gene is critical because of its putative role in the causal pathway of neurodegenerative diseases including Parkinson's disease (PD). However, there is a lack of clarity regarding the link between the main H1 haplotype and risk of PD. Inconsistencies in reported association may be driven by genetic variability in the populations studied to date.

Patient-level and system-level determinants of stroke fatality across 16 large hospitals in Ghana and Nigeria: a prospective cohort study.

Background: Every minute, six indigenous Africans develop new strokes. Patient-level and system-level contributors to early stroke fatality in this region are yet to be delineated. We aimed to identify and quantify the contributions of patient-level and system-level determinants of inpatient stroke fatality across 16 hospitals in Ghana and Nigeria.

Preputial cyst in the newborn: A case report from Africa.

Cysts of the prepuce are rare, and documented reports from the English literature are mostly from Asia. Presentations in children are worrisome to the parents. We report a case of a preputial cyst occurring in a neonate who was brought to our facility due to parental anxiety.

Assessment of sleep knowledge among medical and dental students in a Nigerian tertiary institution: a cross-sectional study.

Purpose: Sleep medicine is a rapidly growing field of Medicine globally. However, studies are lacking on the knowledge of Nigerian medical and dental students on sleep and the different types of sleep disorders. Thus, we assessed the knowledge, interest and awareness of Nigerian medical and dental students about sleep medicine.

Secondhand smoke exposure is independently associated with stroke among non-smoking adults in West Africa.

Background: Stroke is a leading cause of disability and mortality worldwide, but little is known about the contribution of secondhand smoke exposure (SHSE) to stroke epidemiology among indigenous Africans.

Objective: To evaluate the association of SHSE with stroke among indigenous Africans.

Methods: We analyzed the relationship of SHSE with stroke among 2990 case-control pairs of adults who had never smoked (identified in the SIREN study) using conditional logistic regression at a two-sided P < 0.

APOE E4 is associated with impaired self-declared cognition but not disease risk or age of onset in Nigerians with Parkinson's disease.

The relationship between APOE polymorphisms and Parkinson's disease (PD) in black Africans has not been previously investigated. We evaluated the association between APOE polymorphic variability and self-declared cognition in 1100 Nigerians with PD and 1097 age-matched healthy controls. Cognition in PD was assessed using the single item cognition question (item 1.

Differential associations between pre-diabetes, diabetes and stroke occurrence among West Africans.

Background: There are limited data from Africa on the burden and associations between pre-diabetes (pre-DM), diabetes mellitus (DM) and stroke occurrence in a region experiencing a profound rise in stroke burden.

Purpose: To characterize the associations between stroke and dysglycemic status among West Africans.

Methods: The Stroke Investigative Research and Educational Network (SIREN) is a multicenter, case-control study involving 15 sites in Ghana and Nigeria.

Frequent vegetable consumption is inversely associated with hypertension among indigenous Africans.

Aims: The relationship between vegetable consumption and hypertension occurrence remains poorly characterized in sub-Saharan Africa. This study assessed the association of vegetable consumption with odds of hypertension among indigenous Africans.

Methods And Results: We harmonized data on prior vegetable consumption and hypertension occurrence (defined as one of the following conditions; systolic blood pressure ≥140 or diastolic blood pressure ≥90 mmHg or previous diagnosis or use of antihypertensive medications) from 16 445 participants across five African countries (Nigeria, South Africa, Kenya, Ghana and Burkina Faso) in the Stroke Investigative Research and Educational Network and Africa Wits-INDEPTH partnership for Genomic studies.
