Association between urban ecological environment quality, socioeconomic disparity, and incidence of type 2 diabetes among middle-aged and elderly populations in the United Kingdom
Urban ecological environment quality and brain aging
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
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…
Estimating the Instantaneous Asymptomatic Proportion With a Simple Approach
Background: The asymptomatic proportion is a critical epidemiological characteristic that modulates the pandemic potential of emerging respiratory virus, which may vary depending on the nature of the disease source, population characteristics, source–host interaction, and environmental factors. Methods: We developed a simple likelihood-based framework to estimate the instantaneous asymptomatic proportion of infectious diseases. Taking the COVID-1…
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…
Preliminary estimation of the basic reproduction number of novel coronavirus (2019-nCoV) in China, from 2019 to 2020
Backgrounds An ongoing outbreak of a novel coronavirus (2019-nCoV) pneumonia hit a major city in China, Wuhan, December 2019 and subsequently reached other provinces/regions of China and other countries. We present estimates of the basic reproduction number, R 0 , of 2019-nCoV in the early phase of the outbreak. Methods Accounting for the impact of the variations in disease reporting rate, we modelled the epidemic curve of 2019-nCoV cases time se…
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 …
Association of time to diagnosis with socioeconomic position and geographical accessibility to healthcare among symptomatic Covid-19 patients
Five-year lung cancer mortality risk analysis and topography in Xuan Wei
Xuan Wei lung cancer mortality has increased continuously since the third national retrospective surveys on the causes of death by the Ministry of Health of the People's Republic of China (2004-2005), especially for local women and residents over 35 years of age. Geographically, lung cancer in Xuan Wei showed unique spatiotemporal clustering. The local lung cancer mortality was significantly correlated with the smoky coal mine geographically. Som…
