Air pollution deaths attributable to fossil fuels: observational and modelling study.

Objectives: To estimate all cause and cause specific deaths that are attributable to fossil fuel related air pollution and to assess potential health benefits from policies that replace fossil fuels with clean, renewable energy sources.

Design: Observational and modelling study.

Methods: An updated atmospheric composition model, a newly developed relative risk model, and satellite based data were used to determine exposure to ambient air pollution, estimate all cause and disease specific mortality, and attribute them to emission categories.

Long-term vaccination strategies to mitigate the impact of SARS-CoV-2 transmission: A modelling study.

Background: Vaccines have reduced severe disease and death from Coronavirus Disease 2019 (COVID-19). However, with evidence of waning efficacy coupled with continued evolution of the virus, health programmes need to evaluate the requirement for regular booster doses, considering their impact and cost-effectiveness in the face of ongoing transmission and substantial infection-induced immunity.

Methods And Findings: We developed a combined immunological-transmission model parameterised with data on transmissibility, severity, and vaccine effectiveness.

Drug-use disorders in the Eastern Mediterranean Region: a glance at GBD 2019 findings.

Purpose: The aim of this study is to investigate drug use disorders which are a major cause of Disability Adjusted Life Years (DALYs) in the Eastern Mediterranean Region (EMR).

Methods: This article is a part of the global burden of diseases (GBD), injuries, and risk factors 2019 study. The GBD modeling approach was used to estimate population-level prevalence of drug use disorders.

Equity in out-of-pocket health expenditure: Evidence from a health insurance program reform in Mexico.

Background: The fragmentation of health systems in low- and middle-income countries (LMICs) deepens health inequities and shifts the economic burden of health care to families via out-of-pocket spending (OOPHE). This problem has been addressed by introducing public health insurance programs for poor people; however, there is a lack of knowledge about how equitable these programs are. We aimed to analyse the long-term effects of the Seguro Popular (SP) voluntary health insurance program, recently phased out and replaced by the Health Institute for Welfare (Instituto de Salud para el Bienestar (INSABI)), on OOPHE equity in the poor Mexican population.

Multimorbidity in patients with acute heart failure across world regions and country income levels (REPORT-HF): a prospective, multicentre, global cohort study.

Background: Multimorbidity (two or more comorbidities) is common among patients with acute heart failure, but comprehensive global information on its prevalence and clinical consequences across different world regions and income levels is scarce. This study aimed to investigate the prevalence of multimorbidity and its effect on pharmacotherapy and prognosis in participants of the REPORT-HF study.

Methods: REPORT-HF was a prospective, multicentre, global cohort study that enrolled adults (aged ≥18 years) admitted to hospital with a primary diagnosis of acute heart failure from 358 hospitals in 44 countries on six continents.

Road traffic injuries and associated mortality in the Islamic Republic of Iran.

Background: Road traffic accidents are a major public health problem globally, causing millions of injuries, deaths and disabilities, and a huge loss of financial resources, especially in low- and middle-income countries.

Aim: To determine the incidence of road traffic injuries and associated mortality from 1997 to 2020 in the Islamic Republic of Iran.

Methods: This retrospective study used data from the Legal Medicine Organization of the Islamic Republic of Iran to estimate the annual rates of road traffic injuries and associated mortality from 21 March 1997 to 20 March 2020.

Elevated mortality among the second-generation (children of migrants) in Europe: what is going wrong? A review.

Introduction: The 'second-generation' (i.e. the children of migrants) represent one of the fastest growing subpopulations of the child and young adult populations in Europe today.

Socioeconomic inequalities in physical, psychological, and cognitive multimorbidity in middle-aged and older adults in 33 countries: a cross-sectional study.

Background: Many physical, psychological, and cognitive disorders are highly clustered among populations with low socioeconomic status. However, the extent to which socioeconomic status is associated with different combinations of these disorders is unclear, particularly outside high-income countries. We aimed to evaluate these associations in 33 countries including high-income countries, upper-middle-income countries, and one lower-middle-income country.

A systematic review of the data, methods and environmental covariates used to map Aedes-borne arbovirus transmission risk.

Background: Aedes (Stegomyia)-borne diseases are an expanding global threat, but gaps in surveillance make comprehensive and comparable risk assessments challenging. Geostatistical models combine data from multiple locations and use links with environmental and socioeconomic factors to make predictive risk maps. Here we systematically review past approaches to map risk for different Aedes-borne arboviruses from local to global scales, identifying differences and similarities in the data types, covariates, and modelling approaches used.

Health workers' experience of providing second-trimester abortion care in Ethiopia: a qualitative study.

Background: Second-trimester abortions are less common than abortions in the first trimester, yet they disproportionately account for a higher burden of abortion-related mortality and morbidity worldwide. Health workers play a crucial role in granting or denying access to these services, yet little is known about their experiences. Ethiopia has been successful in reducing mortality due to unsafe abortion over the past decade, but access to second trimester abortion remains a challenge.

How is ethnicity reported, described, and analysed in health research in the UK? A bibliographical review and focus group discussions with young refugees.

Background: The ethnicity data gap pertains to 3 major challenges to address ethnic health inequality: 1) Under-representation of ethnic minorities in research; 2) Poor data quality on ethnicity; 3) Ethnicity data not being meaningfully analysed. These challenges are especially relevant for research involving under-served migrant populations in the UK. We aimed to review how ethnicity is captured, reported, analysed and theorised within policy-relevant research on ethnic health inequities.

Expansions to the MGDrivE suite for simulating the efficacy of novel gene-drive constructs in the control of mosquito-borne diseases.

Objective: The MGDrivE (MGDrivE 1 and MGDrivE 2) modeling framework provides a flexible and expansive environment for testing the efficacy of novel gene-drive constructs for the control of mosquito-borne diseases. However, the existing model framework did not previously support several features necessary to simulate some types of intervention strategies. Namely, current MGDrivE versions do not permit modeling of small molecule inducible systems for controlling gene expression in gene drive designs or the inheritance patterns of self-eliminating gene drive mechanisms.

Conversational AI and Vaccine Communication: Systematic Review of the Evidence.

Background: Since the mid-2010s, use of conversational artificial intelligence (AI; chatbots) in health care has expanded significantly, especially in the context of increased burdens on health systems and restrictions on in-person consultations with health care providers during the COVID-19 pandemic. One emerging use for conversational AI is to capture evolving questions and communicate information about vaccines and vaccination.

Objective: The objective of this systematic review was to examine documented uses and evidence on the effectiveness of conversational AI for vaccine communication.

Global-, Regional-, and National-Level Impacts of the COVID-19 Pandemic on Tuberculosis Diagnoses, 2020-2021.

Evaluating cross-country variability on the impact of the COVID-19 pandemic on tuberculosis (TB) may provide urgent inputs to control programs as countries recover from the pandemic. We compared expected TB notifications, modeled using trends in annual TB notifications from 2013-2019, with observed TB notifications to compute the observed to expected (OE) ratios for 170 countries. We applied the least absolute shrinkage and selection operator (LASSO) method to identify the covariates, out of 27 pandemic- and tuberculosis-relevant variables, that had the strongest explanatory power for log OE ratios.

Catastrophic health expenditure during the COVID-19 pandemic in five countries: a time-series analysis.

Background: The COVID-19 pandemic disrupted health systems in 2020, but it is unclear how financial hardship due to out-of-pocket (OOP) health-care costs was affected. We analysed catastrophic health expenditure (CHE) in 2020 in five countries with available household expenditure data: Belarus, Mexico, Peru, Russia, and Viet Nam. In Mexico and Peru, we also conducted an analysis of drivers of change in CHE in 2020 using publicly available data.

Objectives: This article describes key data sources and methods used to estimate hearing loss in the United States, in the Global Burden of Disease study. Then, trends in hearing loss are described for 2019, including temporal trends from 1990 to 2019, changing prevalence over age, severity patterns, and utilization of hearing aids.

Design: We utilized population-representative surveys from the United States to estimate hearing loss prevalence for the Global Burden of Disease study.

Global diversity and antimicrobial resistance of typhoid fever pathogens: Insights from a meta-analysis of 13,000 Typhi genomes.

Background: The Global Typhoid Genomics Consortium was established to bring together the typhoid research community to aggregate and analyse serovar Typhi (Typhi) genomic data to inform public health action. This analysis, which marks 22 years since the publication of the first Typhi genome, represents the largest Typhi genome sequence collection to date (n=13,000).

Methods: This is a meta-analysis of global genotype and antimicrobial resistance (AMR) determinants extracted from previously sequenced genome data and analysed using consistent methods implemented in open analysis platforms GenoTyphi and Pathogenwatch.

Inequitable Financial Protection in Health for Indigenous Populations: the Mexican Case.

Background: There is an important gap in the literature concerning the level, inequality, and evolution of financial protection for indigenous (IH) and non-indigenous (NIH) households in low- and middle-income countries. This paper offers an assessment of the level, socioeconomic inequality and middle-term trends of catastrophic (CHE), impoverishing (IHE), and excessive (EHE) health expenditures in Mexican IHs and NIHs during the period 2008-2020.

Methods: We conducted a pooled cross-sectional analysis using the last seven waves of the National Household Income and Expenditure Survey (n = 315,829 households).

Spatial distribution of COVID-19 patients in Sri Lanka.

Background: A new type of viral pneumonia, which has been named Coronavirus disease (COVID-19) began in Wuhan, China in late 2019 and has spread across the world since then. It has claimed more than 370 million confirmed cases and over 5.6 million deaths have been reported globally by the end of January 2022.

The burden of ischemic heart disease and the epidemiologic transition in the Eastern Mediterranean Region: 1990-2019.

It has been estimated that in the next decade, IHD prevalence, DALYs and deaths will increase more significantly in EMR than in any other region of the world. This study aims to provide a comprehensive description of the trends in the burden of ischemic heart disease (IHD) across the countries of the Eastern Mediterranean Region (EMR) from 1990 to 2019. Data on IHD prevalence, disability-adjusted life years (DALYs), mortality, DALYs attributable to risk factors, healthcare access and quality index (HAQ), and universal health coverage (UHC) were extracted from the Global Burden of Disease (GBD) database for EMR countries.

Reversal of trends in global fine particulate matter air pollution.

Ambient fine particulate matter (PM) is the world's leading environmental health risk factor. Quantification is needed of regional contributions to changes in global PM exposure. Here we interpret satellite-derived PM estimates over 1998-2019 and find a reversal of previous growth in global PM air pollution, which is quantitatively attributed to contributions from 13 regions.
