Choice of measures of vaccination and estimates of risk of pediatric pertussis

BackgroundVaccination uptake at the individual level can be assessed in a variety of ways, including traditional measures of being up-to-date (UTD), measures of UTD that consider dose timing, like age-appropriate vaccination, and risk reduction from individual doses. This analysis compared methods of operationalizing vaccination uptake and corresponding risk of pertussis infection.MethodsCity-wide case-control study of children in Philadelphia aged 3 months through 6 years, between 2001 and 2013. Multiple logistic regression was used to isolate the independent effects of each measure of vaccination uptake and the corresponding relative odds of pertussis.ResultsBeing UTD on vaccinations was associated with a 52% reduction in risk of pertussis (OR 0.48, 95% CI: 0.34, 0.69). Evaluation of delayed receipt of vaccine versus on-time UTD yielded similar results. There was a decrease in risk of pertussis for each additional dose received with the greatest reduction in pertussis infection observed from the first (OR 0.48, 95% CI: 0.28, 0.83) and second dose (OR 0.17, 95% CI: 0.08, 0.34). Additional doses conferred minimal additional protection in this age group.ConclusionExamining vaccination status by individual doses may offer improved predictive capacity for identifying children at risk for pertussis infection compared to the traditional UTD measure.

Correlates of stages of change of smoking among inhabitants of deprived neighbourhoods

BACKGROUND: This study examines the prevalence and correlates of stages of change of smoking, in terms of psychosocial, structural and sociodemographic factors, among inhabitants of deprived neighbourhoods. METHODS: Cross-sectional data were obtained from a survey on health related behaviour. Subjects were 2009 current and former smokers, aged 20-46, living in deprived neighbourhoods in Rotterdam, the second largest city in the Netherlands. Three groups of smokers were formed according to the stages of change-definitions of the Transtheoretical Model: smokers not planning to quit (precontemplators), smokers planning to quit (contemplators/preparators) and former smokers (actors/maintainers). Smokers planning to quit and smokers not planning to quit were compared regarding psychosocial factors (attitude, social norm, self-efficacy), structural factors (neighbourhood problems, material deprivation, financial problems, employment status) and sociodemographic factors (age, gender, marital status, cultural background, educational level). Former smokers were compared with smokers planning to quit regarding structural and sociodemographic factors. Logistic regression was used to assess correlates of stages of change. RESULTS: Smokers planning to quit (prevalence = 19%) reported a more positive attitude, stronger social norms and higher self-efficacy expectations in quitting smoking than smokers not planning to quit (prevalence = 57%). Smokers planning to quit less often were Dutch-born, more often had attended higher vocational schooling or university and more often reported experiencing two or more neighbourhood problems compared to smokers not planning to quit. Former smokers (prevalence = 24%) were older, more often Dutch-born, married, employed and higher educated, compared to smokers planning to quit. Furthermore, former smokers less often reported material deprivation and financial problems than smokers planning to quit. CONCLUSION: Among people living in deprived neighbourhoods, different factors correlate with different stages of change of smoking. Implications for health promotion are discussed.

对《医疗事故处理条例》的几点认识--学习《医疗事故处理条例》的一点体会

国务院颁布的《医疗事故处理条例》（以下简称《条例》）在吸收、总结原《医疗事故处理办法》（以下简称《办法》）实施十几年以来正反两方面经验教训的基础上，对《办法》作了许多重大的修改：《条例》扩大了医疗事故的主体与范围，提出了防范医疗事故的一些重要措施，授权医学会独立担纲医疗事故技术鉴定工作，赋予了患者更多的权利，规定医疗事故民事责任争议可以“私了”，制定了更为规范的医疗事故的赔偿制度等。《条例》作出的这些新规定必将使医疗事故得以更加科学、客观、公正、公平、合理的解决。认真学习、把握《条例》的这些新规定，很好地透视《条例》的立法宗旨与原则，必将极大地提高学习、宣传《条例》的主动性与积极性，更好地推进《条例》的贯彻执行工作。     

The analysis of case-control studies of the efficacy of screening for recurrence of cancer

Occasionally, the efficacy of screening for cancer recurrence has been evaluated by means of case-control studies. However, these studies generally have not been designed and analyzed in a manner that will yield an unbiased result. The commentary shows that by adhering to the principles developed for the analysis of studies of the efficacy of screening for the presence of a given cancer in persons with no history of this disease, a case-control study of screening for recurrence will improve its chances of obtaining valid findings.
