Effects of PM2.5 Exposure in Different Air Quality Grades on Daily Outpatient Visits for Childhood Asthma in Shijiazhuang, China

Asthma is a common chronic inflammatory disorder that is more prevalent in children than in adults.China has seen an increasing prevalence of childhood asthma in recentdecades[1].Earlier studies have shown that air particulate matter (PM),particularly fine particulate matter(PM2.5)[2],is an important factor triggering childhood asthma. Since nationalPM2.5data were nota vailabl euntil 2013,

Ambient Temperature and Outpatient Visits for Acute Exacerbation of Chronic Bronchitis in Shanghai: A Time Series Analysis

The association between ambient temperature and acute exacerbation of chronic bronchitis （AECB） was still unknown. Therefore, we performed an epidemiological study in a large hospital of Shanghai to explore the relationship about temperature and outpatient visit for AECB. We adopted a quasi-Poisson generalized additive models and distributed lag nonlinear models to estimate the accumulative effects of temperature on AECB across multiple days. We found significant non-linear effects of cold temperature on hospital visits for AECB, and the potential effect of cold temperature might last more than 2 weeks. The relative risks of extreme cold （first percentiles of temperature throughout the study period） and cold （10th percentile of temperature） temperature over lags 0-14 d were 2.98 [95% confidence intervals （CI）： 1.77, 5.04] and 1.63 （95% Ch 1.21, 2.19）, compared with the 25th percentile of temperature. However, we found no positive association between hospital visits and hot weather. This study showed that exposure to both extreme cold and cold temperatures were associated with increased outpatient visits for AECB in a large hospital of Shanghai.

Association between Ambient Air Pollution and Outpatient Visits for Acute Bronchitis in a Chinese City

Objective To investigate the short-term association between outdoor air pollution and outpatient visits for acute bronchitis,which is a rare subject of research in the mainland of China.Methods A time-series analysis was conducted to examine the association of outdoor air pollutants with hospital outpatient visits in Shanghai by using two-year daily data（2010-2011）.Results Outdoor air pollution was found to be associated with an increased risk of outpatient visits for acute bronchitis in Shanghai.The effect estimates of air pollutants varied with the lag structures of the concentrations of the pollutants.For lag06,a 10 μg/m3 increase in the concentrations of PM10,SO2,and NO2 corresponded to 0.94%（95% CI：0.83%,1.05%）,11.12%（95% CI：10.76%,11.48%）,and 4.84%（95% CI：4.49%,5.18%） increases in hospital visits for acute bronchitis,respectively.These associations appeared to be stronger in females（P〈0.05）.Between-age differences were significant for SO2（P〈0.05）,and between-season differences were also significant for SO2（P〈0.05）.Conclusion Our analyses have provided the first evidence that the current air pollution level in China has an effect on acute bronchitis and that the rationale for further limiting air pollution levels in Shanghai should be strengthened.

The Outpatient Clinic Visit: Expectations and Fulfilment of Perceived Needs in Adolescents with Type 1 Diabetes

Background: To make outpatient visits for adolescents with diabetes successful, it is important for health care professionals to meet the adolescents’ needs and wishes. Aims: The aim is to investigate adolescents’ expectations of an outpatient diabetes clinic visit in comparison to what was deemed to be delivered and contrast this outcome in adolescents with self-reported high- and low-diabetes distress respectively. Methods: All adolescents in Sweden with type 1 diabetes, aged 15 to 18 years, were identified via The National Pediatric Diabetes Registry (SWEDIABKIDS) and asked to complete an online questionnaire regarding their expectations and the support received during the outpatient diabetes clinic visit. Results: 453 adolescents completed the survey. Boys’ expectations of discussion topics were mainly met while girls, especially those with diabetes distress, felt their discussion needs were not met regarding quality-of-life aspects. Conclusions: Although adolescents’ expectations are in general met during the diabetes outpatient clinic visit, aspects related to living with diabetes are not being met especially among female adolescents who reported diabetes distress. This study shows a gender difference both regarding expected discussion topics and what was deemed covered. Practice Implications: A multi-professional, individual person-centred care approach is needed at the diabetes outpatient clinic. This paper proposes that agenda setting performed by the adolescent, and agreed by the physician, prior to the outpatient clinic visit could facilitate individualized care and better meet the adolescents’ needs in a shared decision-making process.
