To examine if there was a monthly variation in HLA-B27-associated uveitis. Retrospective review of all individuals presenting to single centre with uveitis from 2009 2020. 577 participants were included. The median age at presentation 40.4 years (IQR 31.1-51.4) and 356 (61.7%) male. 141 (24.4%) diagnosed ankylosing spondylitis. incidence HLA-B27 greatest August (winter) lowest March (autumn). On univariate analysis, an inverse relationship between mean air temperature (β-2.704, p < 0.001) sunlight hours (β-0.221, = 0.003), positive rainfall (β 0.324, 0.006) humidity 1.741, 0.006). multivariate (β-4.846, 0.002) association 2.033, 0.008). the impact shifted negative (β-0.446, 0.017) lost significance. effect more pronounced for non-Caucasian ethnicities those without In New Zealand, episodes are influenced by changes higher winter months.

Joint effects of temperature and humidity with PM2.5 on COPD

BMC Public Health, Год журнала: 2025, Номер 25(1)

Опубликована: Фев. 3, 2025

Abstract Background Particulate matter less than 2.5 microns in aerodynamic diameter (PM ) is a significant air pollutant known to adversely affect respiratory health and increase the incidence of chronic obstructive pulmonary disease (COPD). Furthermore, climate change exacerbates these impacts, as extreme temperatures relative humidity (RH) levels can intensify effects PM . This study aims examine joint , temperature, RH on risk COPD. Methods A case–control was conducted among 1,828 participants from 2017 2022 (995 COPD patients 833 controls). The radial basis function interpolation utilized estimate participants' individual mean differences 1-day, 7-day, 1-month periods. Logistic regression models examined associations environmental exposures with adjusting for confounders. Joint by quartiles temperature were also examined. Results We observed that 1 µg/m 3 7-day associated 1.05-fold 1.06-fold OR ( p < 0.05 ). For RH, we U-shaped optimal identified 21.2 °C, 23.8 °C respectively, 73.8%, 76.7%, 75.4% respectively effect show high (> 23.5 °C) both extremely low (69.3%) (80.9%) generally exacerbate COPD, especially over longer exposure durations. Conclusion underscore importance pollution control comprehensive research mitigate context change.

Novel MOF-based autonomous humidity control materials for energy-efficient indoor moisture regulation

Building and Environment, Год журнала: 2024, Номер 261, С. 111757 - 111757

Опубликована: Июнь 18, 2024

The concept of autonomous humidity control material (AHCM) is inspired by phase change material. AHCM a new type functional sorbent It can adsorb/release sufficient water vapor at the target relative level and autonomously maintain indoor set value/range without external intervention, which cannot be achieved conventional sorbents (e.g., zeolite, silica gel, etc.). In this study, novel metal-organic framework (MOF) based prepared, its application for energy-efficient moisture has been investigated. MOF-AHCM an S-shaped isotherm, large porosity, high adsorption capacity. trigger points desorption occur 60 % 40 RH, respectively. means regulate to fall within 40%–60 fits thermal comfort range recommended ASHRAE well. physicochemical hygrothermal characteristics synthesized MOF-ACHM have assessed. Full-scale chamber tests were carried out verify ability experimental results show that significantly mitigate fluctuation autonomously. Furthermore, numerical simulation performed investigate impact on building energy consumption in different regions globally, namely, arid, semiarid, dry, moist, wet areas. reveal excellent capacity reduce latent cooling demand HVAC systems most climates, especially moist

Indoor Air Quality and Perceived IAQ Symptoms at Small and Medium Food Enterprises in Malaysia

Environment-Behaviour Proceedings Journal, Год журнала: 2025, Номер 10(31), С. 205 - 214

Опубликована: Янв. 30, 2025

Workers in SME food industries are exposed to emissions from cooking processes that cause adverse health effects. This study evaluated the association of IAQ parameters with perceived symptoms. The most reported symptoms were fatigue, heavy-headedness, and headache. revealed significant associations between CO2 fatigue (p = 0.0340), temperature itching or burning eyes 0.0111), humidity hoarse dry throat symptom 0.0013). findings underscore importance addressing SMEs improve workers’ working conditions.

Indoor air humidity revisited: Impact on acute symptoms, work productivity, and risk of influenza and COVID-19 infection

International Journal of Hygiene and Environmental Health, Год журнала: 2023, Номер 256, С. 114313 - 114313

Опубликована: Дек. 27, 2023

Recent epidemiological and experimental findings reconfirm that low indoor air humidity (dry air) increases the prevalence of acute eye airway symptoms in offices, result lower mucociliary clearance airways, less efficient immune defense, deteriorate work productivity. New research also support environmental conditions for risk infection influenza COVID-19 virus is lowest Goldilocks zone 40–60% relative (RH) by decrease airways' susceptibility, which can be elevated particle exposure. Furthermore, RH generation infectious laden aerosols exhaled from infected people. In general, elevation dry health airways concomitantly with viability virus. Thus, negative effects ventilation outdoor (low absolute humidity) should assessed according to 1) weakened functionality 2) increased possible transmissibility virus, 3) evaporation containing droplets out droplet nuclei (also at high room temperature), their floating time air. The removal acid-containing ambient filtration pH, viruses, infection, synergistically may further increase dilution pollutants compared beneficial control center RH, an essential factor optimal additional positive impact on symptoms, productivity, reduced infection.

Environmental pollutants including ultrafine particulate matter (UFPs) and adverse meteorological conditions pose significant public health impacts, particularly affecting respiratory health. This study aims to elucidate the synergistic effects of cold-humid UFPs exposure on health, utilizing Carbon Black Nanoparticles (CB-NPs) as surrogates for UFPs. Through comprehensive lung function tests, histopathological examinations, biomarker analyses, this research focuses modulation oxidative stress signaling pathways NF-κB activation. Male Balb/c mice were exposed specific concentrations CB-NPs (30-50 nm in diameter, 0.184 mg/(kg·day)) a controlled environmental chamber mimicking cold (10°C/14°C) humid (90 % RH) over three weeks. The results indicate that alone increased function, (ROS, GSH, MDA), inflammation (IL-6, TNF-α, IL-1β), apoptosis (Caspase 3, Caspase 8, 9), alterations tissue. Furthermore, these notably more severe under combined with conditions. These suggest are not solely concentration-dependent but exacerbated by contexts. It is evident Vitamin E (100 mg/kg/day) can attenuate effects, underscoring its potential protective agent against stressor-induced air Our findings factors pollutant significantly impact providing valuable insights design healthier indoor environments development strategies mitigate risks.
