Joint effects of prenatal PM2.5 and heavy metals on preterm birth
Background Preterm birth (PTB) is a global health concern. The combined effects of prenatal PM 2.5 and heavy metal exposures on PTB risk remain unclear. Methods A nested case-control study included 111 PTB cases and 124 controls from Chongqing. Maternal blood concentrations of 18 trace elements were measured in mid-pregnancy. Fine particulate matter (PM 2.5 ) exposure data were obtained from the Tracking Air Pollution in China (TAP). Residential …
Erac knowledge, attitudes, and practices among obstetrics and gynecology medical staff
Introduction This study aimed to assess the knowledge, attitudes, and practices (KAP) of obstetrics and gynecology medical staff concerning enhanced recovery after cesarean section (ERAC). Methods A multi-center cross-sectional survey was conducted between February 22 and March 31, 2025, in 10 hospitals located across various regions of China. A structured questionnaire was employed to collect data on participants’ demographic characteristics and…
National environmental health risk assessment of short-term air pollution effects on cardiovascular disease in Australia
Background Although there is substantial evidence linking ambient air pollution to increased cardiovascular disease (CVD) risk, the specific effects of different air pollutants in Australia remain unclear, and quality-assessed evidence is lacking. We aimed to examine the short-term effects of air pollution exposure on the risk of CVD-related health outcomes in Australia and evaluate the quality of available evidence to enable tailored actions. Me…

Association between risk of preterm birth and long-term and short-term exposure to ambient carbon monoxide during pregnancy in chongqing, China
Our findings suggest that short-term exposure to low levels of CO may have protective effects against preterm birth, while long-term exposure to low concentrations of CO may reduce the risk of both preterm and very preterm birth. Moreover, our study indicated that very preterm birth is more susceptible to the influence of long-term exposure to CO during pregnancy, with acute CO exposure exhibiting a greater impact on preterm birth. It is imperati…
Associations between maternal exposure to ambient air pollution and very low birth weight
Introduction There have been many researches done on the association between maternal exposure to ambient air pollution and adverse pregnancy outcomes, but few studies related to very low birth weight (VLBW). This study thus explores the association between maternal exposure to ambient air pollutants and the risk of VLBW, and estimates the sensitive exposure time window. Methods A retrospective cohort study analyzed in Chongqing, China, during 20…
Association between High Ambient Temperatures and Road Crashes in an Australian City with Temperate Climate
(1) Background: High ambient temperatures are associated with increased morbidity and mortality rates, and some evidence suggests that high temperatures increase the risk of road crashes. However, little is known regarding the burden of road crashes attributable to no-optimal high temperatures in Australia. Therefore, this study examined the effects of high temperatures on road crashes using Adelaide in South Australia as a case study. (2) Method…
Association between Maternal Exposure to Ambient Air Pollution and the Risk of Preterm Birth
Recent study results on the association between maternal exposure to ambient air pollution with preterm birth have been inconsistent. The sensitive window of exposure and influence level of air pollutants varied greatly. We aimed to explore the association between maternal exposure to ambient air pollutants and the risk of preterm birth, and to estimate the sensitive exposure time window. A total of 572,116 mother-newborn pairs, daily concentrati…
The impact of policy on the intangible service efficiency of the primary health care institution- based on China’s health care reform policy in 2009
Objectives Analyzing the impact of the China’s health care reform policy in 2009 on the intangible service efficiency of PHCI and exploring the way to improve the service efficiency of PHCI. Methods The Malmquist productivity index based on the Data Envelopment Analysis (DEA) was used to measure the variation of TFP and its decomposition of PHCI before and after the implementation of the health care reform policy in 2009. Then, the Tobit model wa…
Red Cross Society in Imperial China, 1904–1912
The Red Cross Society was introduced to China in the 1900s, when the nation was under the authoritarian reign of Qing dynasty. Famines and rebellions, along with the invasion of foreign military forces, created tremendous humanitarian crises that the corrupted imperial government was incapable to address. The Red Cross model was found to be a pragmatic solution by Chinese philanthropists. Using archived press releases, correspondences, and govern…
