Article
Full-text available
Turkey has successfully introduced health system changes and provided its citizens with the right to health to achieve universal health coverage, which helped to address inequities in financing, health service access, and health outcomes. We trace the trajectory of health system reforms in Turkey, with a particular emphasis on 2003-13, which coinci...

Full-text available
In almost all countries, development of health systems that are responsive to the challenge of prevention and treatment of non-communicable diseases (NCDs) is a priority. NCDs consist of a vast group of conditions, but in terms of premature mortality, emphasis has been on cardiovascular disease, cancer, diabetes, and chronic respiratory diseases—di...
Article
Development assistance for health has increased every year between 2000 and 2010, particularly for HIV/AIDS, tuberculosis, and malaria, to reach US$26·66 billion in 2010. The continued global economic crisis means that increased external financing from traditional donors is unlikely in the near term. Hence, new funding has to be sought from innovat...

Background To effectively combat the rising incidence of syphilis, the Brazilian Ministry of Health (MoH) created a National Rapid Response to Syphilis with actions aimed at bolstering epidemiological surveillance of acquired, congenital syphilis, and syphilis during pregnancy complemented with communication activities to raise population awareness...
Article
Background The global burden of diabetes is rising rapidly, yet there is little evidence on individual-level diabetes prevention activities undertaken by health systems in low-income and middle-income countries (LMICs). Here we describe the population at high risk of developing diabetes, estimate diabetes prevention activities, and explore sociodem...
Article
Full-text available
Cardiovascular disease risk factors (CVDRF), in particular diabetes and hypertension, are chronic conditions which carry a substantial disease burden in Low- and Middle-Income Countries. Unlike HIV, they were neglected in the Millenium Development Goals along with the health services required to manage them. To inform the level of health service re...
Article
Full-text available
Background: Testing for the risk factors of cardiovascular disease, which include hypertension, diabetes, and hypercholesterolaemia, is important for timely and effective risk management. Yet few studies have quantified and analysed testing of cardiovascular risk factors in low-income and middle-income countries (LMICs) with respect to sociodemogr...
Article
Importance: Aspirin is an effective and low-cost option for reducing atherosclerotic cardiovascular disease (CVD) events and improving mortality rates among individuals with established CVD. To guide efforts to mitigate the global CVD burden, there is a need to understand current levels of aspirin use for secondary prevention of CVD. Objective:...

BACKGROUND Conversational agents (CAs), or chatbots, are computer programs that simulate conversations with humans. The use of CAs in healthcare settings is recent and rapidly increasing, which often translates to poor reporting of the CA development and evaluation processes, and unreliable research findings. We developed and published a conceptual...

Objective The inverse relationships between chronic disease multimorbidity and health-related quality of life (HRQoL) have been well-documented in the literature. However, the mechanism underlying this relationship remains largely unknown. This is the first study to look into the potential role of functional limitation as a mediator in the relation...
Article
Full-text available
Despite an evolving need to provide surgical health care globally, few health systems, particularly in low-income and middle-income countries (LMICs), can sufficiently provide such care. The vast majority of the world's people-an estimated 5 billion-are unable to access safe and affordable surgical health care when they need it. This is a significa...

Full-text available
The Sustainable Development Goals include a target to reduce the global maternal mortality ratio (MMR) to less than 70 maternal deaths per 100,000 live births by 2030, with no individual country exceeding 140. However, on current trends the goals are unlikely to be met. We used the empirically calibrated Global Maternal Health microsimulation model...
Article
Full-text available
Maternal mortality is a major global health challenge. Although progress has been made globally in reducing maternal deaths, measurement remains challenging given the many causes and frequent underreporting of maternal deaths. We developed the Global Maternal Health microsimulation model for women in 200 countries and territories, accounting for in...

Background: Economic losses due to herpes simplex infections in low- and middle-income countries (LMICs) are unknown. We estimated economic and quality-of-life losses due to genital herpes in 2019, in 90 LMICs, and from 2020 to 2030 in 45 countries in the World Health Organization (WHO) Africa. We additionally estimated economic losses due to huma...

Methods: Secondary data analysis of adul...
Article
Background Previous studies of type 1 diabetes in childhood and adolescence have found large variations in reported incidence around the world. However, it is unclear whether these reported incidence levels are impacted by differences in country health systems and possible underdiagnosis and if so, to what degree. The aim of this study was to estim...

Full-text available
Background Historically, the international development community has often held the view that those living in extreme poverty (at less than $1.90/day) are likely to have a low prevalence of cardiovascular disease (CVD) risk factors due to calorie scarcity, a largely plant-based diet, and physical labor. Evidence on CVD risk factor prevalence among...
Article
Full-text available
Background: Conversational agents (CAs), also known as chatbots, are computer programs that simulate human conversations by using predetermined rule-based responses or artificial intelligence algorithms. They are increasingly used in health care, particularly via smartphones. There is, at present, no conceptual framework guiding the development of...
Article
Full-text available
Background: Conversational agents (CAs) are increasingly used in health care to deliver behavior change interventions. Their evaluation often includes categorizing the behavior change techniques (BCTs) using a classification system of which the BCT Taxonomy v1 (BCTTv1) is one of the most common. Previous studies have presented descriptive summaries...

Antimicrobial resistance (AMR) may negatively impact surgery patients through reducing the efficacy of treatment of surgical site infections, also known as the “primary effects” of AMR. Previous estimates of the burden of AMR have largely ignored the potential “secondary effects,” such as changes in surgical care pathways due to AMR, such as differ...

Background In the prevention of cardiovascular disease, a WHO target is that at least 50% of eligible people use statins. Robust evidence is needed to monitor progress towards this target in low-income and middle-income countries (LMICs), where most cardiovascular disease deaths occur. The objectives of this study were to benchmark statin use in LM...

The majority of biomedical research is funded by public, governmental, and philanthropic grants. These initiatives often shape the avenues and scope of research across disease areas. However, the prioritization of disease-specific funding is not always reflective of the health and social burden of each disease. We identify a prioritization disparit...
