Background The novel coronavirus disease 2019 (COVID-19) has infected 1.9% of the world population by May 2, 2021. Since most previous studies that examined risk factors for mortality and severity were based on hospitalized individuals, population-based cohort are called to provide evidence can be extrapolated general population. Therefore, we aimed examine associations comorbidities with in individuals COVID-19 diagnosed 2020 Ontario, Canada. Methods findings We conducted a retrospective...
Abstract Near-surface atmospheric moisture is a key environmental and hydro-climatic variable that has significant implications for the natural human systems. However, high-resolution data are severely lacking fine-scale studies. Here, we develop first 1 km high spatial resolution dataset of monthly index collection in China (HiMIC-Monthly) over long period 2003~2020. HiMIC-Monthly generated by light gradient boosting machine algorithm (LightGBM) based on observations at 2,419 weather...
Tuberculosis (TB) is an infectious disease of major public health concern. The has demonstrated large space-time variations. This study aims to explore the dynamics TB cases in economically and geographically dynamic province China with specific references control for policy makers. Data on all reported from 2009 2012 were collected program at Zhejiang Provincial Center Disease Control Prevention. We employed time series exploratory spatial data analyses, including Moran’s I, Local Getis’s G...
Abstract. Human-perceived thermal comfort (known as human-perceived temperature) measures the combined effects of multiple meteorological factors (e.g., temperature, humidity, and wind speed) can be aggravated under influences global warming local human activities. With most rapid urbanization largest population, China is being severely threatened by aggravating stress. However, variations stress in at a fine scale have not been fully understood. This gap mainly due to lack high-resolution...
Rationale: Recent experimental and clinical studies suggest that exogenous carbon monoxide (CO) at lower concentrations may have beneficial effects under certain circumstances, whereas population-based epidemiologic of environmentally relevant CO exposure generated mixed findings.Objectives: To examine the acute ambient on respiratory tract infection (RTI) hospitalizations.Methods: A time series study was conducted. Daily emergency hospital admission air pollution data in Hong Kong were...
Abstract Background The pathogenesis and pathophysiology of eosinophilia‐related chronic cough such as non‐asthmatic eosinophilic bronchitis variant asthma are still not clear. Objective This study is to examine the potential role traffic‐related air pollution (TRAP) in inflammation responses. Methods Non‐sensitized guinea‐pigs were exposed TRAP an urban traffic tunnel or kept a filtered environment for 7 14 days. Reflexive was measured using citric acid allyl isothiocyanate (AITC)...
Objectives Previous studies on geographical disparities in healthcare access have been limited by not accounting for the provider’s capacity, a key determinant of supply and demand relationships. Design This study proposed spatial coverage modelling approach to evaluate hospital care using Canadian Institute Health Information data 2007. Setting focusses accessibility inpatient emergency cares at both levels individual administrative regions Local Integration Network (LHIN) levels. Measures...
Objectives: The relationship between long-term exposure to occupational noise and hearing loss has been extensively documented. We aimed assess spatial temporal changes in the burden of noise-induced (ONIHL) 204 countries territories with varying socio-demographic indexes (SDI) from 1990 2019. Design: Temporal trends age-standardized disability-adjusted life year rates (ASDR) for ONIHL were estimated by sex, age, SDI level, country, geographic region used Joinpoint model calculate annual...
Healthcare workers (HCWs) are at high risk of latent tuberculosis infection (LTBI), and the baseline prevalence LTBI among frontline TB HCWs in southeastern China remains unknown. The aim this study was to assess analyze factors associated with both individual institutional level.Based on a cross-sectional design, 31 out 89 TB-designated hospitals Zhejiang Province were selected. Information control measures collected through field visits each selected hospitals. All from recruited answer...
Heatwaves are among the deadliest weather-related disasters. They not only seen in summer but also may appear spring and autumn, especially under climate warming. Although mechanisms of summertime heatwaves have been extensively studied, how they differ from autumn seasons possibly season-dependent poorly understood. Here we examine specific processes associated with spring, summer, southern China during 1961–2020. We show that all three intensifying frequency, duration, intensity, exhibit...
Rationale Evidence for the association between fine particulate matter (PM 2.5 ) and mortality among patients with tuberculosis (TB) is limited. Whether greenness protects air pollution-related multidrug-resistant (MDR-TB) completely unknown. Methods 2305 reported in Zhejiang Ningxia were followed up from MDR-TB diagnosis until death, loss to follow-up or end of study (31 December 2019), an average 1724 days per patient. 16-day averages contemporaneous Normalised Difference Vegetation Index...
Under global warming and rapid urbanization, heat extremes, ozone pollution, their co-occurrences are emerging posing severe risks to human health. However, possibly different characteristics of independent days (IHD), pollution (IOP) compound heat-ozone (CHOP) events unclear. In this study, we present an investigation the spatial distribution mechanisms associated with IHD, IOP CHOP during May–October in 2014–2022 by taking Guangdong-Hong Kong-Macao Greater Bay Area (GBA) China as example....
