This study analyzes the behavior of airborne pollen in relation to meteorological parameters. It may be helpful understand consequences this interaction on health population Madrid form respiratory allergic pathologies. To end, a multivariate analysis was carried out using Spearman’s linear correlation coefficient between concentrations atmosphere six types tree (Cupressaceae, Olea, Platanus, Pinus, Ulmus and Populus) each variables: relative humidity, precipitation, temperature, wind, radiation insolation. The parameters most correlated with types, monthly values, are temperature insolation, followed by humidity. In addition, there more significant correlations variables Cupressaceae, Pinus Platanus types. Radiation is parameter highest ρ especially > 0.8. Wind only variable correlations, all them positive, number statistically results obtained from daily values lower compared Populus, Cupressaceae Olea. inter-relationship grains can lead an increase cases pollinosis, when positive correlations.

Simulation of pollen–humidity interactions and origin of airborne sub-pollen particles

The Science of The Total Environment, Journal Year: 2025, Volume and Issue: 966, P. 178706 - 178706

Published: Feb. 1, 2025

Airborne pollen can break down into sub-pollen particles (SPPs) due to osmotic forces, which penetrate deep the respiratory system, triggering heightened allergic responses. This study aimed simulate pollen-humidity interactions for several types including Golden wattle (Acacia Pycnantha), Perennial Ryegrass (Lolium Perenne) and Insignis pine (Pinus Radiata) using a novel experimental setup featuring rotating drum incubating airborne at different humidity levels. An assortment of aerosol instrumentation characterisation methods were used aerosols inside drum. SPP formation, ranging from 0.15 5 μm, was observed in high levels 95 % 99 relative (RH). Notably, evidence formation RH revealed first time, with their sizes 0.18 μm. These observations indicate species-specific response varying conditions lay foundation assessing potential various species across Australia. In summary, therefore have generate SPPs both Ryegrass. Additionally, setup, techniques, presented herein support future studies isolated influence meteorological parameters on pollen.

Demographics and clinical features of pediatric patients with allergic rhinitis: a single-center study from Western Turkey

BMC Pediatrics, Journal Year: 2025, Volume and Issue: 25(1)

Published: March 6, 2025

Allergic rhinitis (AR) is a disease that has significant effects on the quality of life people and exhibits different phenotypic features with clinical findings. By analyzing data pediatric patients, we aimed to reveal relationship between demographic laboratory gain awareness about allergic phenotypes in children. Demographic data, complaints, physical examination findings, atopy biomarkers are retrospectively analyzed assess impact aeroallergens phenotype. In study 301 AR patients (median age 11 years; 66.1% male), sneezing (79.1%) was most common complaint, pallor nasal mucosa primary finding (83.1%). Persistent symptoms were reported by 62.1%, 60.5% polysensitized. Notably, 42.5% had asthma, often associated concurrent sensitization mold or animal dander (p ≤ 0.05). Pollen prevalent allergen (65.8%), increases pollen < 0.001) = 0.003) age. Patients more 0.026) persistent Nasal congestion predominantly seen house dust mite-sensitized (78.4% concha hypertrophy, p 0.001). Overall, it found 59.7% monosensitized 63.7% polysensitized complaints. This study, conducted Western Turkey revealed high prevalence polysensitization, particularly dander. Polysensitized older, exhibited higher IgE levels, frequently rhinorrhea. Furthermore, polysensitization linked severe symptoms, emphasizing need for personalized treatment strategies these patients. Our findings highlight importance developing individualized region-specific approaches enhance effectiveness management.

Purpose To clarify the associations of climatic indices with chronic respiratory symptoms, a final aim to approximate effects climate change on them. Methods An e-mail survey was directed members Finnish Pensioners` Federation. The mean 20-years’ precipitation and temperature in each subjects’ home municipality were obtained from Meteorological Institute, separately for summer winter. Adjusted multivariate models utilized investigate rhinosinusitis, cough, wheezing dyspnea, sleep apnea. Results There 6189 responders 283 municipalities. Chronic rhinosinusitis cough most prevalent southeastern regions country, where counts highest. In models, winter increased risks (adjusted OR 1.79 (1.29-2.49) per 100 mm, p < 0.001, 1.57 (1.19 2.07), = respectively). Wheezing dyspnea apnea not associated indices. Conclusion long-term precipitation. Given anticipated increase Northern America Europe, prevalences may there.
