Population modelling of nilotinib exposure vs. longitudinal BCR::ABL1 response in patients with chronic phase chronic myeloid leukaemia using a semimechanistic disease model.

Aims: This study aims to evaluate the exposure-efficacy relationship of nilotinib and longitudinal BCR::ABL1 levels in patients with newly diagnosed Philadelphia chromosome-positive chronic myeloid leukaemia in chronic phase (CML-CP) and those who are imatinib-resistant or intolerant using a semimechanistic disease model.

Methods: The analysis included 489 CML-CP patients from 3 nilotinib trials (NCT00109707; NCT00471497; NCT01043874) with duration of follow-up ranging from 2 to 9 years. The semimechanistic disease model of CML-CP consisted of quiescent leukaemic stem cells, proliferating drug-susceptible and -resistant bone marrow cells.

Assessing the scalability of health system interventions in Africa: protocol for a Delphi study.

Background: There is widespread enthusiasm for scaling interventions to strengthen health systems. However, little is known about the scalability of such interventions in Africa. In this study, we seek to assess the scalability of interventions for improving the functionality of health systems in Africa, as a key to large-scale implementation strategy of interventions with potential for impact.

World Health Organization African Region national heads of units of diagnostics and laboratory services meetings proceedings.

Background: In the World Health Organization (WHO) African Region, many cases of serious and preventable diseases remain unmanaged because appropriate and good quality diagnostic support is not available at all levels within countries' health systems. Diagnostic and laboratory services influence the efficiency and effectiveness of both clinical and public health functions, including diagnosis, treatment, health promotion, disease prevention, surveillance and response, and research. Essential to global health security, these services are vital to decision-making processes by clinicians, epidemiologists, public health specialists, and health policymakers.

Mapping inequalities in health service coverage in Africa: a scoping review.

Objective: In this scoping review, we aim to consolidate the evidence on inequalities in service coverage in Africa using a comprehensive set of stratifiers. These stratifiers include place of residence, race/ethnicity/culture/language, occupation, gender/sex, religion, education, socioeconomic status and social capital. Our approach provides a more holistic understanding of the different dimensions of inequality in the context of universal health coverage (UHC).

Population-level impact of switching to 1-dose human papillomavirus vaccination in high-income countries: examining uncertainties using mathematical modeling.

Background: A concern in high-income countries is that switching to 1-dose human papillomavirus (HPV) vaccination could cause a rebound in HPV infection and cervical cancer if 1-dose efficacy or duration were inferior to 2 doses. Using mathematical modeling and up-to-date trial-based data, we projected the population-level effectiveness of switching from 2-dose to 1-dose vaccination under different vaccine efficacy and duration assumptions in high-income countries.

Methods: We used HPV-ADVISE (Agent-based Dynamic model for VaccInation and Screening Evaluation), a transmission-dynamic model of HPV infection and cervical cancer, varying key model assumptions to identify those with the greatest impact on projections of HPV-16 and cervical cancer incidence over time: 1) 1-dose vaccine efficacy and vaccine duration, 2) mechanisms of vaccine efficacy and duration over time, 3) midadult (>30 years of age) sexual behavior, 4) progression to cervical cancer among midadults, and 5) vaccination coverage and programs.
