“…Secondly, a viral etiology of fever and respiratory tract infection syndrome was most prevalent among children aged < 4 years in Shaanxi province, which is consistent with the finding that both Male-IPD and Female-IPD are significantly higher in the 0-14 age group in Chiang-Mai province (Martin et al, 2013). Third, an early study that concentrated on the effects of socioeconomic status (SES) suggests that PM 2.5 -associated hospital admission rates for all respiratory outcomes were predominantly positive in children aged 1 to 9 years in 12 California counties, from 2000 to 2005, consistent with the exceptionally high hospital admissions of the 0-14 age group in Chiang-Mai for both genders (Yap et al, 2013). Apart from these perplexing causes, there are some possible biological mechanisms, which can greatly affect to air pollution at the study site.…”

“…Numerous studies have found an intimate relationship between hospital admissions and meteorological parameters, such as outdoor temperature, atmospheric concentration of fine particles and trace gaseous species in different cities around the world (Cengiz and Terzi, 2012;Szponar et al, 2012;Le et al, 2013;Wang et al, 2013;Yap et al, 2013). In spite of various reports associated with ecological analysis of the epidemiological study using ambient PM data/ meteorological parameters obtained from the air quality station and fixed sites, there are limited numbers of studies focusing on the impacts of haze on hospital admissions (Emmanuel, 2000;Xie et al, 2014;Zhang et al, 2014).…”

The aims of this study were to investigate the impact of meteorological parameters and trace gas concentrations on daily hospital walk-ins and admissions in Chiang-Mai province, Thailand, during 2007Thailand, during -2013. Advanced statistical models, including t-tests, Analysis of Variance (ANOVA), Multiple Linear Regression Analysis (MLRA) and Incremental Lifetime Particulate Matter Exposure (ILPE), were constructed using meteorological data from the Pollution Control Department (PCD), Ministry of Natural Resources and Environment (MNRE), Thailand, and the Thai Meteorological Department at Chiang-Mai Province Air Quality Observatory Site (TMCS) as well as the number of walk-in and admitted patients at Nakornping Hospital, Chiang-Mai (NHCM). The results showed that all trace gaseous species and PM 10 were significantly higher during the "haze episode" than during the "non-haze period." The FTIR spectra highlight the relatively homogeneous organic functional compositions of PM 2.5 collected from urban, suburban and rural observatory sites, indicating that agricultural waste burning plays an important role in air quality during the "haze episode." The effect of age on susceptibility to respiratory diseases was investigated by separating the dataset into four groups (i.e., < 15 years, 15-59 years, 60-74 years and ≥ 75 years). The ANOVA results revealed a significant increase in hospital walk-ins and admissions for both genders in the < 15 years group (p < 0.005). MLRA revealed the significantly highest impacts of CO on hospital walk-ins for both genders. The predicted ILPE of PM 10 showed the highest values for both genders during the "haze-episode" in 2007, with average values of 3.338 ± 0.576 g and 1.838 ± 0.317 g for male and female outdoor workers, respectively, over an exposure duration of 25 years.

“…The fourth limitation was the lack of information on parental smoking and ambient air pollution. The prevalence rate of parental smoking and percentage of air pollution exposure is associated with educational level and family income (29,30). Air pollution is related to urbanization and a higher population density has been shown to result in more severe air pollution in Taiwan (31).…”

Oligohydramnios increases the risk of respiratory hospitalization in childhood: a population-based study

et al. 2013

Background: Pulmonary hypoplasia is associated with reduced lung function in infancy. The aim of this study was to evaluate the hypothesis that children exposed to oligohydramnios display an increased risk of hospitalization for respiratory illness by using a population-based matched-cohort design. Methods: We used three nationwide population-based data sets to identify 5,228 women who gave birth during 2004 to 2007 and were diagnosed with oligohydramnios during the third trimester of pregnancy. A cohort of 20,912 unaffected pregnant women was matched with these cases, according to neonatal sex and gestational age, maternal age and education, and level of prenatal care. Respiratory hospitalization and respiratory failure were defined using discharge diagnostic codes. results: Oligohydramnios-exposed children had an 8% higher incidence rate of respiratory hospitalization and an 80% higher incidence rate of respiratory failure, compared with children without oligohydramnios exposure. This risk remained after adjusting for all potential risk factors. Cox regression analyses indicated that the adjusted hazard ratios of respiratory hospitalization and respiratory failure were 1.07 (95% confidence interval (CI): 1.01-1.15; P = 0.030) and 2.20 (95% CI: 1.26-3.84; P = 0.005), respectively. conclusion: Children exposed to oligohydramnios during the third trimester of pregnancy display an increased risk of hospitalization for respiratory illness. P ulmonary hypoplasia is uncommon in the perinatal period but is a critical cause of death in newborn infants. Oligohydramnios is one of the abnormalities most commonly associated with pulmonary hypoplasia (1). Lung growth is influenced by physical factors such as the intrauterine space, lung liquid volume and pressure, and breathing movements. For lungs to develop, the physical space in the fetal thorax must be adequate, and amniotic fluid must be drawn into the lungs through fetal breathing movements, leading to their distension. Physical forces play vital roles in regulating fetal lung growth and maturation (2,3). During lung development, the main physical force experienced by the lung is stretching induced by breathing movements and lung fluid in the air spaces (4). Oligohydramnios reduces the intrathoracic cavity size, disrupting fetal lung growth and leading to the development of pulmonary hypoplasia (5,6).Oligohydramnios is a critical factor affecting short-and long-term clinical prognoses. In a study by Lindner et al. (7), neonates exposed to oligohydramnios experienced shortterm respiratory morbidity (including high ventilator settings, increased incidence of hypoxemia and hypercapnia, and pulmonary hypertension) and tended to experience more air leaks than did healthy neonates. Pulmonary hypoplasia is also associated with reduced lung function in infancy (8). Previous studies have reported the short-term perinatal outcomes of pregnancies complicated by oligohydramnios (9-12). A small case-control study found that infants born following the preterm rupture of membranes a...

“…Not surprisingly, the relationship between socio-economic conditions and pollution exposure is expected to vary across communities and countries as also shown by Yap et al They showed that in lower-SES South Coast areas, PM2.5-associated hospital admission rates for all respiratory outcomes were predominantly positive whereas results in the Central Valley were variable, often tending toward the null. These distinct patterns could be attributed to the heterogeneity of regional confounders as well as the seasonal variation of emission sources of PM2.5 (Yap, Gilbreath et al, 2013).…”

The United Nations have projected the world population to reach 9.6 billion by 2050 and that, by then, over 50% of the world population will be living in urban areas. This continuing population growth and accompanying urbanization lead to serious concerns about clean water and food for all, but also about climate change and pollution. Soil and water pollution are directly affecting the crops grown for consumption, and air pollution is affecting our mucosal barriers in the respiratory and gastro-intestinal tract on a daily basis. This review provides an overview of the different types of pollution, and the health effects triggered by especially air pollution ranging from heart disease, pulmonary disease, cancer, to fatal respiratory infections. In addition, the differences in how pollution

Abstract: These distinct patterns could be attributed to the heterogeneity of regional confounders as well as the seasonal variation of emission sources of PM2.5. Composite SES is one potential factor for increasing susceptibility to air pollution.
