Effects of green space exposure on acute respiratory illness in community-dwelling older people
Increased out-of-home green space exposure was significantly associated with the reduced risk of acute respiratory illness (ARI) in a prospective cohort of community-dwelling older adults in Hong Kong. • The association of green space with ARI was more evident for taller shrubs and woodlands than for grassland. • The inverse relationship between green space exposure and ARI incidence was more pronounced in active transportation mode. Few studies …
Kidney failure-related excess mortality during the first three years of the Covid-19 pandemic in the United States
Our study observed high levels of excess kidney failure-related mortality during the first two years of the pandemic, followed by a notable decline in the third year. This highlights the effectiveness of current policies and prevention measures implemented to mitigate the impact of the pandemic
The climate change impacts and responses index
Identifying climate change risks, vulnerabilities of exposed populations, and implemented responses to climate change are crucial for developing effective strategies to mitigate climate hazards. However, existing climate change assessment indexes still have some limitations, such as insufficient consideration of policy response, limited coverage of countries, and lack of a multidimensional perspective. In this study, we developed a novel climate …
Comparison of the prevalence of opioid use among U.S. adults with cardiac conditions before and during the Covid-19 pandemic
Limited data are available on the prevalence of prescription opioid use among patients with cardiac conditions who were exposed to increased risks of cardiac events including myocardial failure and cardiac arrest. According to the U.S. National Health Interview Survey, we evaluated the prevalence of opioid use in patients with cardiac conditions who reported prescription opioid use in the past 12 months and 3 months in 2019 and 2020, respectively…
Relationship between temperature variability and daily hospitalisations in Hong Kong over two decades
Background: Studies have highlighted the impacts of temperature variability (TV) on mortality from respiratory diseases and cardiovascular diseases, with inconsistent results specifically in subtropical urban areas than temperate ones. We aimed to fully determine TV-associated health risks over a spectrum of diseases and various subgroups in a subtropical setting. Methods: Using inpatient data from all public hospitals in Hong Kong from 1999 to 2…
How Transportation Restriction Shapes the Relationship Between Ambient Nitrogen Dioxide and Covid-19 Transmissibility
Background: Several recent studies reported a positive (statistical) association between ambient nitrogen dioxide (NO 2 ) and COVID-19 transmissibility. However, considering the intensive transportation restriction due to lockdown measures that would lead to declines in both ambient NO 2 concentration and COVID-19 spread, the crude or insufficiently adjusted associations between NO 2 and COVID-19 transmissibility might be confounded. This study a…
The co-circulating transmission dynamics of Sars-CoV-2 Alpha and Eta variants in Nigeria
BACKGROUND: The COVID-19 pandemic poses serious threats to public health globally, and the emerging mutations in SARS-CoV-2 genomes has become one of the major challenges of disease control. In the second epidemic wave in Nigeria, the roles of co-circulating SARS-CoV-2 Alpha (ie, B.1.1.7) and Eta (ie, B.1.525) variants in contributing to the epidemiological outcomes were of public health concerns for investigation. METHODS: We developed a mathema…
Source-Specific Volatile Organic Compounds and Emergency Hospital Admissions for Cardiorespiratory Diseases
Knowledge gaps remain regarding the cardiorespiratory impacts of ambient volatile organic compounds (VOCs) for the general population. This study identified contributing sources to ambient VOCs and estimated the short-term effects of VOC apportioned sources on daily emergency hospital admissions for cardiorespiratory diseases in Hong Kong from 2011 to 2014. We estimated VOC source contributions using fourteen organic chemicals by positive matrix …
