The phase 3 trial of the RTS,S/AS01 malaria vaccine candidate showed modest efficacy against Plasmodium falciparum malaria, but was not powered to assess mortality endpoints. Impact projections and cost-effectiveness estimates for longer timeframes than follow-up across a range settings are needed inform policy recommendations. We aimed public health impact routine use in African settings.We compared four transmission models their predictions impact. used data 32 months or parameterise...

Medicare beneficiaries’ medical needs, and where beneficiaries undergo treatment, have changed dramatically over the past two decades. Twenty years ago, most spending growth was linked to intensive inpatient (hospital) services, chiefly for heart disease. Recently, much of has been attributable chronic conditions such as diabetes, arthritis, hypertension, kidney These are treated not in hospitals but outpatient settings by patients at home with prescription drugs. Health reform must address...

Appropriate treatment of life-threatening Plasmodium falciparum malaria requires in-patient care. Although the proportion severe cases accessing care in endemic settings strongly affects overall case fatality rates and thus disease burden, this is generally unknown. At present, estimates mortality are driven by prevalence or clinical incidence data, ignoring differences resulting from variations access. Consequently, impact preventive interventions on burden have not been validly compared...

Scale-up of malaria preventive and control interventions over the last decade resulted in substantial declines mortality morbidity from disease sub-Saharan Africa many other parts world. Sustaining these gains will depend on health system performance. Treatment provides individual benefits by curing infection preventing progression to severe as well community-level reducing infectious reservoir averting emergence spread drug resistance.

The United States spends more on health care than any European country. Previous studies have sought to explain these differences in terms of system capacity, access technologies, gross domestic product, and prices. We examine disease prevalence treatment rates for ten the most costly conditions between countries using surveys noninstitutionalized population age fifty older. Disease medication are much higher countries. Efforts reduce U.S. chronic illness should remain a key policy goal.

The RTS,S/AS01 malaria vaccine candidate recently completed Phase III trials in 11 African sites. Recommendations for its deployment will partly depend on predictions of public health impact endemic countries. Previous these used only limited information underlying properties and have not considered country-specific contextual data. Each trial cohort was simulated explicitly using an ensemble individual-based stochastic models, many hypothetical profiles. true profile estimated by Bayesian...

Objectives Current guidelines for the control of soil-transmitted helminths (STH) recommend deworming children and other high-risk groups, primarily using school-based (SBD) programmes. However, targeting individuals all ages through community-wide mass drug administration (cMDA) may interrupt STH transmission in some settings. We compared costs cMDA to SBD inform decision-making about future updates policy. Design conducted activity-based microcosting 2 years Benin, India Malawi within an...

Background Malaria disease shifts to older ages when interventions are applied only the youngest children, and incidence will resurge in endemic settings intervention coverage decreases. This has consequences for deployment of long-lasting insecticide treated nets or infection blocking vaccines (e.g. pre-erythrocytic vaccines). These delay acquisition immunity, with result that previously protected individuals may experience pathology later life due undeveloped waning immunity. Here we use a...
