Background: Air pollutants may aggravate atopic dermatitis (AD). However, the association between Air Quality Index (AQI) and incidence of AD remains unknown.
Objective: To investigate association between AQI and incidence of AD, using the nationwide cohort in the Taiwan National Health Insurance Research Database (NHIRD).
Methods: We included 21,278,938 participants from the NHIRD not diagnosed with AD before 2008. Long-term average AQI value, obtained from the Taiwan Air Quality Monitoring System Network, before AD diagnosis was calculated and linked for each participant.
Results: 199,205 incident cases of AD were identified from 2008 to 2018. Participants were classified into 4 quantiles (Q) by AQI value. With the lowest quantile, Q1, as reference, the AD risk increased significantly in the Q2 group (adjusted hazard ratio [aHR]: 1.29, 95% confidence interval [CI]: 1.04-1.65), Q3 group (aHR: 4.71, 95% CI: 3.78-6.04), and was highest in the Q4 group (aHR: 13.20, 95% CI: 10.86-16.60). As AQI treated as a continuous variable, an increase of 1 unit of AQI value added 7% of AD risk (aHR, 1.07, 95% CI: 1.07-1.08).
Limitations: The NHIRD lacks detailed information on individual subjects.
Conclusions: The results demonstrated a significant positive association between AQI and incidence of AD with a clear dose-response relationship.

Weather and air quality conditions have been anecdotally reported to be related to symptom fluctuations in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), but this has never been empirically investigated. This exploratory study aims to examine the effects of weather and air quality on daily fluctuations of chronic pain and fatigue in women with ME/CFS. In an intensive longitudinal design, 58 participants with ME/CFS provided daily pain and fatigue ratings for an average of 61 days.

Objective: Canine oral neoplasia is often detected late in the course of the disease, necessitating radical surgeries frequently combined with adjuvant chemotherapy or radiotherapy for positive outcomes. Although there has been extensive analytical and epidemiologic work on human oral cancer, research in veterinary medicine has been lacking. This study aimed to evaluate the prevalence and risk factors associated with canine oral neoplasia to enhance early detection by improving screening.

Background: The rising incidence of environmental pollution has heightened concerns regarding the impact of pollutant variations on public health.
Methods: Time series analysis models and BP neural network models were utilized to investigate both univariate and multivariate predictions of HIV/AIDS cases. To evaluate the combined effects of pollutants on HIV/AIDS cases, we employed weighted quantile sum (WQS) regression, a quantile-based g-computation approach (Qgcomp) and Bayesian kernel machine regression (BKMR).

The environment is the most important stratum in the epidemiological triad of a parasitic disease and any variations in the environmental factors may decide the dynamic occurrence and existence of different lifecycle stages of these parasites. The present study investigated the correlations between key biometeorological and demographical parameters with the incidence of different gastrointestinal parasites and hemoparasites among goats. Four hundred and thirty-two goats were screened for parasitic infection in a yearlong survey conducted from July 2022 to June 2023 in the Teaching Veterinary Clinical Complex, Mannuthy, Kerala, India.
