[Initial study of trap and identification of environmental pollens and fungi spores in Samborondon, Ecuador]. / Estudio inicial de captación e identificación de pólenes y hongos ambientales en Samborondón, Ecuador.

OBJETIVO: To identify and registry the most important aeroallergens trapped at the aerobiology station in the city of Samborondon, Ecuador. METHODS: Pollen grains and fungal spore counts were performed according to the standardized technique with a Hirst-type collection equipment, Burkard spore trap for seven days, following the recommendations of the National Allergy Bureau (NAB) of the American Academy of Allergy Asthma and Immunology (AAAAI). The equipment was installed on the roof of the Universidad de Especialidades Espiritu Santo (UEES), 25 m above ground level, coordinates: 2°07 ́57 ́ ́S 79°52 ́06 ́ ́W, in the city of Samborondon. The sampling period was performed from November 2022 to April 2023. RESULTS: We identified the following pollen families: Poaceae (258 grains/m3), Apocynaceae (Plumeria rubra pc) (214 grains/m3), Lamiaceae (180 grains/m3), Asteraceae Ambrosía spp.- (60 grains/m3), Chenopodiacea (27 grains/m3), Myrtaceae (17 grains/m3), Pinaceae (11 grains/m3), Betulaceae (7 grains/m3). Also identified fungical spores: Fuzariella spp./Leptosphaeria spp. (1899/m3), Cladosporium spp. (1407/m3), Nigrospora spp. (1183/m3), Dreschlera/Helmintosporum spp. (329/m3), Alternaria spp. (98/m3), Pithomyces spp. (79/m3), Curvularia spp. (48/m3), Stemphylium spp. (46/m3). CONCLUSIONS: We reported the first study of aerobiology (capture and identification of environmental pollens and fungi) in the city of Samborondon. The inhabitants of this area are exposed to different aeroallergens with a predominance of Poaceaes pollen and Fuzzariella spp./Leptosphaeria spp. spores. The identified allergens should be part of the usual allergy studies. The results of this first preliminary study should be compared with information from the forthcoming years, which will help to identify variations in the concentration of seasonal aeroallergens, annual fluctuations, and extend the traps to other parts of the city.

Appraisal of lens opacity with mometasone furoate/formoterol fumarate combination in patients with COPD or asthma.

BACKGROUND: Long-term corticosteroid use may increase cataract risk. The Lens Opacities Classification System (LOCS) III ranked lens opacities as Class 1: 0.5-0.9 unit; Class 2: 1.0-1.4 units; or Class 3: ≥1.5 units in clinical trials of combined mometasone furoate and formoterol (MF/F) administered by metered-dose inhaler (MDI). We examined retrospectively shifts in lenticular opacity in patients with chronic obstructive pulmonary disease (COPD) or asthma. METHODS: We analyzed pooled LOCS III data from two COPD studies and separately analyzed LOCS III data from an asthma study. COPD subjects were randomized to twice daily MF/F 200/10 µg, MF/F 400/10 µg, MF 400 µg, F 10 µg, and placebo; asthma subjects were randomized to MF/F 200/10 µg, MF/F 400/10 µg, fluticasone propionate/salmeterol (FP/S) 250/50 µg, and FP/S 500/50 µg. Lenticular opacity changes were analyzed post hoc for proportions of subjects with LOCS III grade increases ≥0.5, ≥1.0, or ≥1.5 units at weeks 26 and 52. RESULTS: Proportions of subjects in the COPD studies with Class 1 (≥0.5 unit), 2 (≥1.0 unit), or 3 (≥1.5 units) increases in LOCS III at week 26 (N = 1675) ranged from 15.5 to 18.6%, 3.3-6.0%, and 0.9-2.2%, respectively. At week 52 (N = 1085), proportions of active-treated subjects with Class 1, 2, or 3 increases in LOCS III ranged from 26.6 to 28.9%, 6.3-10.7%, and 2.6-5.9%, respectively. Treatment differences in lenticular shifts were generally small and nonsignificant in the asthma study. CONCLUSION: No clinically relevant trends were observed in the LOCS III assessment of lenticular shifts during treatment of COPD and asthma patients, although further study may be needed to confirm the findings presented here. In these trials, MF/F effects on lens opacity were not observed. (Clinicaltrials.gov numbers: NCT00383435, NCT00383721, and NCT00379288.).

Variación de la somnolencia diurna y proteína c reactiva en los integrantes de la IX Expedición Antártica Ecuatoriana, 2004 / Variation of daytime drowsiness and protein c reagent on the members of the ix antarctic ecuadorian expedition, 2004

Se ha demostrado que las condiciones climáticas y laborales extremas en la Antártida, alteran la relación sueño-vigilia, modificando los grados de somnolencia diurna. Objetivos: determinar la correlación entre el score de somnolencia diurna y la PCR cuantitativa como marcador inflamatorio en 20 expedicionarios ecuatorianos sometidos a horarios laborales estrictos durante 10 semanas en el verano peninsular Antártico y su relación con el score de somnolencia diurna en el trópico. Tipo de estudio: longitudinal, prospectivo, realizado a un grupo de expedicionarios durante el verano polar Antártico. Resultados: la escala de Epworth inicial una semana antes de la expedición, reportó un paciente 5(n=20) con hiepersomnolencia diurna excesiva con 11 puntos, el mismo que disminuyó 4 puntos en la escala final, clasificándose como no hipersomnolente. Se observó que todo el grupo tuvo una disminución en la escala de Epworth final vs. inicial con tendencia de al menos 1 punto (p=0.04). La correlación entre PCR y escala de Epworth inicial fue positiva con “r” Pearson de (0,55); esta correlación desapareció hacia el final de las 10 semanas de expedición. La PCR en el 100(n=20) fue de (0,17+/-0,16) al inicio y de (0,17+/-0,19) al final con un valor referencial normal de 0 a 1,20 mg/dL. Conclusiones: el estrés ambiental y laboral al que fueron sometidos los expedicionarios aumentó el estado de alerta en todo el grupo en relación con la escala de Epworth del trópico. La PCR inicial y final no alcanzó niveles significativos, manteniéndose siempre dentro de los parámetros normales, comprobándose la no existencia del componente inflamatorio al no haber hipersomnolencia diurna excesiva.

The extreme climatic and working conditions in the Antarctica alter the relation sleep-alertness, modifying the degrees of daytime drowsiness. Type of study: longitudinal, prospective, practiced on a group of expeditionary people during the Antarctic Polar summer. Objectives: to determine correlation between the score of daytime drowsiness and the quantitative RPC as inflammatory marker in 20 Ecuadorian expeditonary people submitted to strict working schedules during 10 weeks in the Antarctic peninsular summer and its connection with the score of daytime drowsiness in the Tropic. Results: the Initial Epworth scale a week before the expedition reported one patient 5 (n=20) with excessive daytime hypersomnia with 11 points. This patient reduced 4 points at the end of the scale, having been classified as non hypersomniac. In was observed that everybody in the group had a decrease in the Epworth scale final vs. initial with tendency of almost 1 point (p=0.04). The correlation between RPC and Initial Epworth scale was positive with “r” Pearson of (0.55); this correlation disappeared towards the end of the 10 weeks of expedition. The RPC in 100 (n=20) was of (0.17 +/-0.16) at the beginning and of (0.17+/-0.19) at the end with a normal referential value from 0 to 1.20 mg/dl. Conclusions: the environmental and working stress that they underwent increased alertness in all the group according to the Epworth scale of the Tropic. The initial and final (RPC) did not reach significant levels either, being always inside the normal parameter, proving the inexistence of the inflammatory component since there was no excessive daytime hypersomnia.

Geographic differences in clinical characteristics and management of COPD: the EPOCA study.

AIMS: Data on differences in clinical characteristics and management of COPD in different countries and settings are limited. We aimed to characterize the profile of patients with COPD in a number of countries and their treatment in order to evaluate adherence to recommendations of international guidelines. METHOD: This was an observational, international, cross-sectional study on patients with physician-diagnosed COPD. Demographic and clinical characteristics, risk factors, and treatment were collected by their physician via an internet web-based questionnaire developed for the study. RESULTS: A total of 77 investigators from 17 countries provided data on 833 patients. The countries with the highest number of patients included were: Argentina (128), Ecuador (134), Spain (162), and Hong Kong (153). Overall, 79.3% were men and 81% former smokers, with a mean FEV1 = 42.7%, ranging from 34.3% in Hong Kong to 58.8% in Ecuador. Patients reported a mean of 1.6 exacerbations the previous year, with this frequency being significantly and negatively correlated with FEV1 (%) (r = -0.256; p < 0.0001). Treatment with short-acting bronchodilators and theophyllines was more frequent in Ecuador and Hong Kong compared with Spain and Argentina, and in patients belonging to lower socioeconomic levels (p < 0.0001 for all comparisons). Inadequacy of treatment with inhaled corticosteroids and theophyllines was high, with significant differences among countries. CONCLUSIONS: Differences in the clinical characteristics and management of COPD were significant across countries. Adherence to international guidelines appears to be low. Efforts should be made to disseminate and adapt guidelines to the socioeconomic reality of different settings.
