Ebola Outbreak Response in the DRC with rVSV-ZEBOV-GP Ring Vaccination.

Background: At the beginning of the 2018-2020 outbreak of Ebola virus disease (EVD) in eastern Democratic Republic of Congo (DRC), no vaccine had been licensed. However, cluster-randomized evidence from Guinea in 2015 had indicated that ring vaccination around new cases (targeting contacts and contacts-of-contacts) with the use of single-dose live-replicating rVSV-ZEBOV-GP vaccine reduced EVD rates starting 10 days after vaccination. Thus, ring vaccination was added to the standard control measures for that outbreak.

Halving premature death and improving quality of life at all ages: cross-country analyses of past trends and future directions.

Background: Although death in old age is unavoidable, premature death-defined here as death before age 70 years-is not. To assess whether halving premature mortality by 2050 is feasible, we examined the large variation in premature death rates before age 70 years and trends over the past 50 years (1970-2019), covering ten world regions and the 30 most-populous nations. This analysis was undertaken in conjunction with the third report of The Lancet Commission on Investing in Health: Global Health 2050: the path to halving premature death by mid-century.

Risk prediction of ischemic heart disease using plasma proteomics, conventional risk factors and polygenic scores in Chinese and European adults.

Plasma proteomics could enhance risk prediction for multiple diseases beyond conventional risk factors or polygenic scores (PS). To assess utility of proteomics for risk prediction of ischemic heart disease (IHD) compared with conventional risk factors and PS in Chinese and European populations. A nested case-cohort study measured plasma levels of 2923 proteins using Olink Explore panel in ~ 4000 Chinese adults (1976 incident IHD cases and 2001 sub-cohort controls).

Online level-2 perspective taking for newly learnt symbols.

Humans demonstrate spontaneous sensitivity to other people's perspectives on object identities in online tasks. Evidence shows that this not only involves representing the mere discrepancy between perspectives, but the content of such perspectives as well (level-2 perspective taking/L2PT). However, this evidence comes from studies using culturally grounded symbols which leaves open the possibility that having extensive, easily accessible background knowledge about an object is necessary for the L2PT effect.

Alcohol and mortality in Mexico: prospective study of 150 000 adults.

Background: Alcohol consumption is a leading cause of premature death globally, but there is no large-scale prospective evidence from Mexico.

Methods: The Mexico City Prospective Study recruited 150 000 adults aged 35 years or older between 1998 and 2004. Participants were followed up until Oct 1, 2022 for cause-specific mortality.

How to undertake respiratory auscultation with infants and children.

Respiratory auscultation involves listening to and interpreting sounds from within the chest. Undertaking respiratory auscultation effectively requires appropriate equipment, knowledge of physiology and pathophysiology and experience in listening to and interpreting breath sounds. Nurses undertaking this procedure must ensure they have the knowledge and skills to do so and work within the limits of their competence.

Infectious pathogens and risk of esophageal, gastric and duodenal cancers and ulcers in China: A case-cohort study.

Infection by certain pathogens is associated with cancer development. We conducted a case-cohort study of ~2500 incident cases of esophageal, gastric and duodenal cancer, and gastric and duodenal ulcer and a randomly selected subcohort of ~2000 individuals within the China Kadoorie Biobank study of >0.5 million adults.

Tobacco control in China.

Chinese men consume around 40% of the world's cigarettes, causing a substantial and growing burden of tobacco-attributed death and disease. In 2005, the Chinese Government ratified the WHO Framework Convention on Tobacco Control, and tobacco control measures have since increased nationwide. To assess tobacco control progress, obstacles, and opportunities, this Review describes the long-term evolution of cigarette consumption and the associated disease burden in mainland China, and the implementation of five important tobacco control strategies advocated by WHO.

Alcohol intake and cause-specific mortality: conventional and genetic evidence in a prospective cohort study of 512 000 adults in China.

Background: Genetic variants that affect alcohol use in East Asian populations could help assess the causal effects of alcohol consumption on cause-specific mortality. We aimed to investigate the associations between alcohol intake and cause-specific mortality using conventional and genetic epidemiological methods among more than 512 000 adults in China.

Methods: The prospective China Kadoorie Biobank cohort study enrolled 512 724 adults (210 205 men and 302 519 women) aged 30-79 years, during 2004-08.

Global Cancer Drug Development-A Report From the 2022 Accelerating Anticancer Agent Development and Validation Meeting.

Rapidly expanding systemic treatment options, combined with improved screening, diagnostic, surgical, and radiotherapy techniques, have led to improved survival outcomes for many cancers over time. However, these overall survival gains have disproportionately benefited patients in high-income countries, whereas patients in low- and middle-income countries (LMICs) continue to experience challenges in accessing timely and guideline concordant care. In September 2022, the Accelerating Anticancer Agent Development and Validation workshop was held, focusing on global cancer drug development.

Plasma Proteomics to Identify Drug Targets for Ischemic Heart Disease.

Background: Integrated analyses of plasma proteomic and genetic markers in prospective studies can clarify the causal relevance of proteins and discover novel targets for ischemic heart disease (IHD) and other diseases.

Objectives: The purpose of this study was to examine associations of proteomics and genetics data with IHD in population studies to discover novel preventive treatments.

Methods: We conducted a nested case-cohort study in the China Kadoorie Biobank (CKB) involving 1,971 incident IHD cases and 2,001 subcohort participants who were genotyped and free of prior cardiovascular disease.

MTHFR and risk of stroke and heart disease in a low-folate population: a prospective study of 156 000 Chinese adults.

Background: The relevance of folic acid for stroke prevention in low-folate populations such as in China is uncertain. Genetic studies of the methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism, which increases plasma homocysteine (tHcy) levels, could clarify the causal relevance of elevated tHcy levels for stroke, ischaemic heart disease (IHD) and other diseases in populations without folic acid fortification.

Methods: In the prospective China Kadoorie Biobank, 156 253 participants were genotyped for MTHFR and 12 240 developed a stroke during the 12-year follow-up.

Conventional and genetic associations of adiposity with 1463 proteins in relatively lean Chinese adults.

Adiposity is associated with multiple diseases and traits, but little is known about the causal relevance and mechanisms underlying these associations. Large-scale proteomic profiling, especially when integrated with genetic data, can clarify mechanisms linking adiposity with disease outcomes. We examined the associations of adiposity with plasma levels of 1463 proteins in 3977 Chinese adults, using measured and genetically-instrumented BMI.

Educational and social inequalities and cause-specific mortality in Mexico City: a prospective study.

Background: Social inequalities in adult mortality have been reported across diverse populations, but there is no large-scale prospective evidence from Mexico. We aimed to quantify social, including educational, inequalities in mortality among adults in Mexico City.

Methods: The Mexico City Prospective Study recruited 150 000 adults aged 35 years and older from two districts of Mexico City between 1998 and 2004.

Genotyping and population characteristics of the China Kadoorie Biobank.

The China Kadoorie Biobank (CKB) is a population-based prospective cohort of >512,000 adults recruited from 2004 to 2008 from 10 geographically diverse regions across China. Detailed data from questionnaires and physical measurements were collected at baseline, with additional measurements at three resurveys involving ∼5% of surviving participants. Analyses of genome-wide genotyping, for >100,000 participants using custom-designed Axiom arrays, reveal extensive relatedness, recent consanguinity, and signatures reflecting large-scale population movements from recent Chinese history.
