John Amuasi is a global health and infectious disease researcher focused on neglected tropical diseases, pandemic preparedness, and One Health initiatives in Africa. Amuasi conducts epidemiological studies on snakebite envenoming, COVID-19, and antimicrobial resistance, while also leading efforts to strengthen clinical trial infrastructure and health research capacity on the continent. The work spans from community-based serosurveys and policy analysis to the coordination of high-level commissions aimed at improving health security.

What are the comparative efficacy and adherence rates of new short-course latent tuberculosis infection (LTBI) regimens versus traditional long-course therapies in high-burden, low-resource settings?

Why this gap exists: While a 2023 network meta-analysis [6] synthesizes general efficacy and adherence data for LTBI regimens, the retrieved evidence lacks direct comparative studies specifically focused on high-burden, low-resource settings, leaving the specific constraints of these environments unresolved.

What is the comparative effectiveness of telemedicine versus traditional in-person care in maintaining essential antenatal coverage and reducing maternal mortality in low-income and middle-income countries during future health system shocks?

Why this gap exists: While abstracts [4], [7], [8], and [9] discuss digital tools and maternity care in low- and middle-income countries, none provide a direct comparative effectiveness analysis of telemedicine versus in-person care regarding maternal mortality during health system shocks, leaving the specific question unresolved.

How does the longitudinal trajectory of maternal stress and resilience during pregnancy specifically mediate the association between social determinants of health (e.g., socioeconomic status, structural inequality) and infant cognitive or emotional development outcomes?

Why this gap exists: While the retrieved literature confirms associations between socioeconomic disadvantage, maternal stress, and infant neurodevelopment, it does not resolve the specific question of how longitudinal trajectories of maternal stress and resilience mediate these associations, as the studies focus on broad correlations or static measures rather than dynamic mediation pathways.

How do specific policy interventions aimed at improving female education and labor force participation accelerate the 'maternal mortality transition' in regions currently experiencing high maternal mortality?

Why this gap exists: While the retrieved literature establishes links between female education, political power, and health outcomes (e.g., [3], [6], [9]), no study directly addresses how specific labor or education policy interventions accelerate the 'maternal mortality transition' in high-mortality regions, leaving the mechanism and impact of such specific policies unresolved.

How does the consumption of plant-based proteins, specifically those high in anti-nutritional factors like phytates and trypsin inhibitors, affect mineral bioavailability and growth outcomes in children relying on these proteins as primary staples?

Why this gap exists: While the retrieved papers confirm that anti-nutritional factors like phytates and trypsin inhibitors reduce mineral bioavailability [0, 2], they focus on general adult health or crop improvement [1, 6] and do not provide direct evidence on the specific growth outcomes in children relying on these proteins as primary staples.
