Drinking water disinfection byproducts (DBPs) have received widespread attention due to their high concentrations and toxicity. However, the correlation between exposure to disinfection byproducts and bladder cancer in published papers is inconsistent. In this study, a time-updated meta-analysis was conducted, which aimed to elucidate the relationship between the historical exposure time and exposure levels of trihalomethanes (THMs) in drinking water and the associated risk of bladder cancer.

Purpose: Previous studies have assessed the impact of air pollution on myopia from the individual level, while none of them have explored the role of air pollution in visual health disparities between different regions from the area level. This ecological study aimed to investigate the impact of ambient air pollution on reduced visual acuity (VA).
Methods: The data were derived from the Chinese National Survey on Students' Constitution and Health (CNSSCH) conducted in 2014 and 2019, which involved 261,833 and 267,106 students respectively.
Association between pets and dry eye symptoms: A Chinese national-based study.
Sci Total Environ
December 2024
Article Synopsis
- - Pet ownership is linked to a higher risk of dry eye symptoms (DES), with a prevalence of 43.6% found in a study of 21,916 Chinese residents aged over 12 during a nationwide survey.
- - The study revealed that pet owners had a 13% increased risk of developing DES, which was even higher among elderly (28% increase) and urban residents (13% increase).
- - The interaction between pet ownership and allergic rhinitis showed a significant combined effect on DES, indicating potential common underlying mechanisms between these conditions.
Background: The relationships between 25-hydroxyvitamin D [25(OH)D] and calcium and age-related macular degeneration (AMD) are unclear.
Objectives: This study aimed to investigate the causal role of 25(OH)D concentrations, calcium concentrations, and dietary supplements use of vitamin D and calcium on risk of AMD and its subtypes.
Methods: Independent genetic variants associated with 25(OH)D and calcium concentrations were used as instrumental variables in published genome-wide association studies (GWASs) of European ancestry.
Article Synopsis
- The study investigates the link between air pollution and dry eye symptoms (DES) during the COVID-19 pandemic, aiming to determine if air pollution posed a higher risk than other factors.
- A nationwide survey with over 21,000 participants found that living near industrial areas was associated with a higher risk of DES, while only sulfur dioxide (SO) showed a significant association with these symptoms.
- The results suggest that other factors like depression, anxiety, and excessive internet use played a more substantial role in increasing DES risk, indicating a potential dampening effect of air pollution during the pandemic due to more time spent indoors.
Aims: To assess the impact of dry eye symptoms (DESs) on health-related quality of life (HRQOL) among Chinese residents.
Methods: A total of 21 916 participants were involved in this nationwide cross-sectional study. All of them completed the Ocular Surface Disease Index-6 and the five-level European Quality of Life 5-Dimensional (EQ-5D) Questionnaire to assess the severity of DES and HRQOL, respectively.
Background: Several studies have previously reported the normal values of corneal volume (CV) in various populations, whereas little is known about the CV distribution in healthy young Chinese adults. Our study aimed to investigate the distribution of CV and its relationships with other ocular biometric parameters among healthy young Chinese adults.
Methods: A total of 1645 eyes from 1645 students at Dali University in Yunnan Province, China, were analyzed.
Prcis: There was a significant inverse linear relationship between age at menopause and open angle glaucoma (OAG). Late menarche (≥13 y) and a history of 5 or more deliveries were significantly associated with an increased risk of OAG.
Purpose: To determine the association between reproductive factors including age at menarche, age at menopause, reproductive period, parity, and the risk of OAG in women.
Purpose: To assess the impacts of area-level socioeconomic and environmental measures on reduced visual acuity (VA).
Methods: This ecological study used the nationally representative cross-sectional data from the Chinese National Survey on Students' Constitution and Health in 2014 (CNSSCH 2014), which included 261,833 participants aged 7 to 22 years randomly selected from 30 mainland provinces in China. Area-level socioeconomic measures assessed included gross domestic product (GDP), population density, density of hospital beds, and nighttime light data measured as the mean digital number (DN) of each region; environmental factors assessed included latitude, annual sunlight duration, and park green space density.
Impact of major age-related eye disorders on health-related quality of life assessed by EQ-5D: a systematic review and meta-analysis.
Graefes Arch Clin Exp Ophthalmol
September 2023
Purpose: This study is to quantitatively estimate the health-related quality of life (HRQOL) impact of major age-related eye diseases (AREDs) including cataract, glaucoma, age-related macular degeneration (AMD), and diabetic retinopathy (DR) assessed by the EuroQoL Five-Dimensional Questionnaire (EQ-5D).
Methods: PubMed, Embase, Cochrane Library, and CINAHL were searched until October 20, 2022. Studies were included if they reported the EQ-5D health utility score (HUS) or visual analogue scale (VAS) score of both AREDs patients and healthy controls.
Background: To assess the relationship between sleep duration and the risk of major eye disorders including myopia, glaucoma, cataract, age-related macular degeneration (AMD), and diabetic retinopathy (DR).
Methods: Databases including PubMed, Embase, Web of Science, and Cochrane library were searched for eligible publications before July 2021. Studies assessing the relationship between sleep duration and any one of the major eye disorders were identified.
Background: There is accumulating evidence of the associations between age-related eye diseases (AREDs) and smoking or dietary factors. We aimed to provide an umbrella review of the published literature pertaining to smoking or dietary intake as risk factors for major AREDs including cataract, glaucoma, age-related macular degeneration (AMD) and diabetic retinopathy.
Methods: We searched for pertinent systematic reviews or meta-analyses in PubMed and Web of Science until 16 April 2022.
