Transforming Maternal and Child Health through Skilled Birth Attendance in Pastoral Ethiopia: Evidence from South Omo Zone
(2025-05-15) Mrs. Roman Tesfaye Abneh
This article presents empirical evidence on the impact of the Hailemariam & Roman Foundation (HRF)’s Reproductive, Maternal, Newborn, and Child Health (RMNCH) interventions implemented between 2021 and 2024 in the Hamar and Bena Tsemay districts of South Omo Zone, Ethiopia. The initiative achieved a 53.8% increase in skilled birth attendance in Hamar Woreda (from 34% to 52.3%) and an 8.6% increase in Bena Tsemay (from 86% to 94.6%), surpassing Ethiopia’s national target of 90% (FMoH, 2020). Over 140 health professionals, 20 health managers, and 23 community leaders were trained, while 64 Traditional Birth Attendants (TBAs) were integrated into the formal referral system —a strategy aligned with WHO recommendations for engaging informal providers to expand maternal health service coverage (WHO, 2015). Additionally, antenatal care (ANC) coverage increased, with over 80% of women attending at least one ANC visit, and 60% completing four or more—a significant improvement from baseline levels. Postnatal care (PNC) within 48 hours rose from under 20% to over 50%, and ambulance referrals quadrupled, enhancing emergency obstetric response. The findings demonstrate the effectiveness of combining health system strengthening, community-based engagement, strategic advocacy, and culturally tailored solutions to significantly improve maternal and neonatal health outcomes in underserved and remote regions, offering a compelling case for scaling up context-specific RMNCH strategies across pastoralist settings in sub-Saharan Africa.
ALTERNATIVE SPLICING AND THE AGING BRAIN IN AFRABIA: NEW FRONTIERS IN DEMENTIA RESEARCH
(2025) Suliyat Abiodun Aremu
AfrAbia, encompassing the Sub‑Saharan Africa and the Arab world, is undergoing rapid demographic change. Although still a relatively young region, its population aged ≥60 years is projected to rise from approximately 74 million in 2020 to over 235 million by 2050 (United Nations, 2019). Dementia prevalence is increasing in parallel, yet epidemiological estimates and care infrastructure remain far below global needs. Here, we highlight the urgent need to integrate molecular biology, especially alternative pre‑mRNA splicing, into AfrAbian dementia research. Alternative splicing (AS) generates proteomic diversity in the brain and undergoes characteristic shifts with aging. AS dysregulation has been implicated in Alzheimer’s disease (AD), frontotemporal dementia (FTD), and related disorders. However, Africans and Arabs are markedly underrepresented in transcriptomic studies, and virtually no data exist on splicing patterns in AfrAbian brains. We outline key demographic and dementia trends in AfrAbia, summarize current knowledge of AS in aging and neurodegeneration, identify gaps in AfrAbian populations, and propose strategic recommendations: profiling AS in local cohorts to discover region‑specific biomarkers, resilience factors, and therapeutic targets. By framing the splicing landscape in AfrAbia, this perspective calls for regionally focused molecular research to meet the coming challenge of dementia.
Nano-Biosensors in Clinical Neuroscience: Opportunities, Challenges, and 2Translational Milestones
(2025) Suliyat Abiodun Aremu
The intersection of nanotechnology and neuroscience has catalyzed the development of nano-biosensors capable of real-time, high-resolution monitoring of brain activity. These nanoscale devices, utilizing materials such as graphene, nanowires, and flexible polymers, offer unprecedented potential for diagnosing and managing neurological disorders by enabling continuous neural recording with minimal invasiveness. This Perspective explores the clinical applications of nano-biosensors, including their use in epilepsy monitoring, Parkinson’s disease management, and brain-computer interfaces. We critically evaluate the opportunities nano-biosensors present for personalized medicine, closed-loop therapies, and minimally invasive diagnostics, alongside the significant challenges related to biocompatibility, device stability, data management, and ethical concerns. Finally, we highlight future directions for interdisciplinary collaboration and regulatory strategies necessary to safely and effectively translate nano-biosensors into clinical practice. While hurdles remain, nano-biosensors may herald a paradigm shift in the way we monitor, understand, and treat brain disorders.
Neuro-Metabolic Disparity Model (NMDM): A Theoretical Framework for Understanding Cognitive Decline in Underrepresented Populations
(2025) Suliyat Abiodun Aremu
Global disparities in brain and mental health are not solely a consequence of genetic or neurobiological factors. Instead, they reflect the cumulative effects of metabolic dysfunction, chronic psychosocial stress, environmental exposures, and systemic inequities that disproportionately affect underrepresented populations. This theoretical paper introduces the Neuro-Metabolic Disparity Model (NMDM), an integrative framework that situates cognitive decline at the intersection of biological and social adversity. Drawing from syndemic theory, population neuroscience, and the exposome framework, the NMDM emphasizes the synergistic effects of metabolic disorders and structural disadvantage on brain aging. The model outlines four core components, embodied biological factors, embedded social determinants, neurocognitive vulnerability pathways, and population-level context—and proposes neuroinflammation, oxidative stress, and blood-brain barrier disruption as key mediators. Cultural resilience and social support are considered potential buffers. This framework provides a foundation for more inclusive and equity-focused neuroscience research, with implications for global brain health policy and practice.
