Challenges in resuscitation and survival factors of in-hospital cardiac arrest with suspected cardiovascular etiology: A multicenter retrospective study in Beijing, China.

Background And Aim: Cardiovascular disease affects both the elderly and younger populations, with cardiogenic arrest being the leading cause of in-hospital cardiac arrest (IHCA). The prognosis of IHCA related to cardiovascular diseases remains uncertain. This study aims to explore the characteristics, outcomes, and survival factors of IHCA with suspected cardiovascular etiology.

Age-Period-Cohort Analysis and Prediction of Falls Disease Burden Attributable to Low Bone Mineral Density in China, 1990-2019.

Objectives: This study aims to comprehensively describe and analyze the disease burden of falls attributed to low bone mineral density (BMD) in China from 1990 to 2019. Furthermore, we seek to predict the future trends of this burden from 2020 to 2030 to inform evidence-based prevention and control strategies.

Methods: Using data from the 2019 Global Burden of Disease (GBD) study, we conducted an in-depth analysis of mortality and disability-adjusted life year (DALY) trends related to falls attributed to low BMD in China from 1990 to 2019.

Relationship between exposure to fine particulate matter and cardiovascular risk factors and the modifying effect of socioeconomic status: a cross-sectional study in Beijing, China.

Accumulating research suggested that long-term exposure to fine particulate matter (PM) is related to cardiovascular disease (CVD). However, evidence regarding the relationship between PM and CVD risk factors remains inconsistent. We hypothesized that this association may be partially modified by socioeconomic status (SES).

Changing spectrum and mortality disparities of etiology of liver cirrhosis in Beijing, China.

Liver cirrhosis remains a major health concern globally, but its epidemiology and etiology evolve with time. However, the changing pattern in etiology and cause of liver-related mortality for patients with cirrhosis are not fully elucidated. Herein, our aim was to characterize the temporal trend of the etiological spectrum and evaluate the impact of etiology on liver-related death among patients with compensated cirrhosis (CC) in Beijing, China.

Prevalence of Metabolic Syndrome and Risk Factors Among Chinese Adults: Results from a Population-Based Study - Beijing, China, 2017-2018.

What Is Already Known About This Topic?: Metabolic syndrome (MetS) is one of the most easily available health indicative markers for cardiovascular diseases, and it has become a major public health problem worldwide due to increasing urbanization and aging populations. The prevalence of MetS increased dramatically in China, however, there are no records of MetS defined by the 2017 Chinese Diabetes Society for Beijing by far.

What Is Added By This Report?: In this study, the data of 24,412 participants aged 18-74 years from a large population-based study in Beijing was collected.

Interruption of Influenza Transmission under Public Health Emergency Response for COVID-19: a Study Based on Real-World Data from Beijing, China.

To estimate the effect of the corona virus disease 2019 (COVID-19) control measures taken to mitigate community transmission in many regions, we analyzed data from the influenza surveillance system in Beijing from week 27 of 2014 to week 26 of 2020. We collected weekly numbers of influenza-like illness (ILI) cases, weekly positive proportion of ILI cases, weekly ILI case proportion in outpatients, and the dates of implementation of COVID-19 measures. We compared the influenza activity indicators of the 2019/2020 season with the preceding five seasons and built two ARIMAX models to estimate the effectiveness of COVID-19 measures declared since January 24, 2020 by the emergency response.

Associations of long-term exposure to air pollution with blood pressure and homocysteine among adults in Beijing, China: A cross-sectional study.

Background: Studies on the hypertensive effect of long-term exposure to air pollution are mixed, and sparse evidence exists regarding its effects on homocysteine (Hcy), another crucial risk factor for cardiovascular disease (CVD).

Methods: We collected data from 23,256 participants aged 18-74 years at baseline (years 2017-2018) from a community-based cohort in China. A linear combination of concentrations from monitoring stations at the participants' home and work addresses, weighted by the time, was used to estimate two-year exposures to particulate matter with fine particles≤2.

Influenza-associated cardiovascular mortality in older adults in Beijing, China: a population-based time-series study.

Objective: This study comprehensively estimated the excess cardiovascular disease (CVD) mortality attributable to influenza in an older (age ≥65 years) population.

Design: Ecological study.

Setting: Aggregated data from administrative systems on CVD mortality, influenza surveillance and meteorological data in Beijing, China.

A new method to estimate the temperature-CVD mortality relationship.

Few detailed, individual-focused studies have researched the added effect of temperature on cardiovascular disease (CVD), particularly in China. Moreover, no prior studies have explored the exposure-response relationship among all populations and different sub-sociodemographic groups. A distributed lag nonlinear model (DLNM) was applied to evaluate the adverse health effects of temperature on CVD mortality for all populations and different sub-sociodemographic groups (by age, sex, educational level, living arrangement, and occupation) in Beijing.

Acute Effects of Particulate Air Pollution on Ischemic Stroke and Hemorrhagic Stroke Mortality.

A large body of literature reported the association of particulate matter (PM) with stroke in high-income countries. Few studies have examined the association between PM and stroke in middle- and low-income countries and considered the types of stroke. In this study, we examined the short-term effects of particulate matter <2.

Mortality burden from seasonal influenza and 2009 H1N1 pandemic influenza in Beijing, China, 2007-2013.

Background: Data about influenza mortality burden in northern China are limited. This study estimated mortality burden in Beijing associated with seasonal influenza from 2007 to 2013 and the 2009 H1N1 pandemic.

Methods: We estimated influenza-associated excess mortality by fitting a negative binomial model using weekly mortality data as the outcome of interest with the percent of influenza-positive samples by type/subtype as predictor variables.

Relationship between fine particulate air pollution and ischaemic heart disease morbidity and mortality.

Objective: To assess the relationship between fine particulate matter (PM2.5) concentration and ischaemic heart disease (IHD) morbidity and mortality.

Methods: A time-series study conducted in Beijing from 1 January 2010 to 31 December 2012.
