流感监测中儿童流感样病例定义探讨 总被引:1,自引:0,他引:1
目的探讨流感监测中儿童流感样病例的定义。方法对武汉地区1994~2004年的流感监测资料进行回顾性统计分析。结果在1003例研究对象中301例(30.01%)被证实存在流感病毒感染,两个年龄组的流感发病率差异有统计学意义(P=0.024),A型和B型流感病毒感染后“卡他症状”(P=0.0242)和“咽痛”(P=0.0091)的出现率差异有统计学意义;进入logistic回归模型的5个变量为:体温(OR=1.555)、发病天数(OR=0.591)、咳嗽(OR=2.369)、卡他症状(OR=1.873)、咽痛(OR=2.061);用“咳嗽伴有卡他症状或咽痛”症状组合预测儿童流感感染的阳性预测值为41.3%,阴性预测值为78.4%,灵敏度为58.8%,特异度为64.1%。结论流感监测中儿童流感样病例较科学合理定义为:发热(体温≥38℃)、咳嗽并伴有卡他症状或咽痛之一者。 相似文献

目的 比较不同临床症状的流感样病例流感检出情况的差异,探讨采用不同流感样病例定义对流感监测结果的影响。方法 根据2015年上海市2家国家级流感监测哨点医院的流感病原学监测数据和病例临床症状,计算不同临床症状(有咳嗽咽痛、仅咳嗽、仅咽痛)的流感样病例流感病毒检出情况,并通过多因素Logistic回归分析流感病毒检出情况的影响因素。结果 2 010例流感样病例中,有咳嗽咽痛者1 105例、仅有咳嗽者270例、仅有咽痛者635例,流感阳性率分别为36.2%、39.3%和15.9%,经分析,有咳嗽咽痛者、仅有咳嗽者的流感阳性检出率均高于仅有咽痛者(均有P<0.05)。对于发病3 d内采样的流感样病例,有咳嗽咽痛、仅有咳嗽者的流感阳性检出率均高于仅咽痛者(均有P<0.05)。多因素Logistic回归分析结果显示,流感病毒检出情况与病例体温(≥ 39℃)(OR=1.719,95%CI:1.389~2.127)、咳嗽(OR=3.046,95%CI:2.377~3.905)有关。结论 建议以"发热(体温≥ 38℃)伴咳嗽症状者"作为流感监测中的流感样病例定义。 相似文献

We reviewed the case definitions used by 21 influenza sentinel-based surveillance networks in Western Europe. Two clinical syndromes were used with a wide range of case definitions that nevertheless shared common criteria. Although there is currently no international consensus, efforts are being undertaken to standardise influenza case definitions in Europe. 相似文献

ObjectiveThe STRONGkids is a nutritional screening tool for hospitalized children, which was found to predict a negative weight for height (WFH) standard deviation score (SDS) and a prolonged hospital length of stay (LOS) in a Dutch population of hospitalized children. This study aimed to test the ease of use and reproducibility of the STRONGkids, and to confirm its concurrent and prospective validity in a Belgian population of hospitalized children.MethodsReproducibility was tested in a cohort of 29 hospitalized children in a tertiary center and validity was tested in 368 children (105 hospitalized in a tertiary and 263 in three secondary hospitals) ages between 0.08 and 16.95 y (median 2.2 y).ResultsSubstantial intrarater (κ = 0.66) and interrater (κ = 0.61) reliabilities were found between observations. STRONGkids scores correlated negatively with WFH SDS of the patients (ρ = –0.23; P < 0.01; odds ratio [OR], 2.47; 95% confidence interval [CI], 1.11–5.49; P < 0.05). It had a sensitivity and negative predictive value (NPV) of respectively 71.9% and 94.8% to identify acutely undernourished children. STRONGkids did not correlate with weight loss during hospitalization, but correlated with LOS (ρ = 0.25; OR 1.96; 95% CI, 1.25–3.07; both P < 0.01) and the set-up of a nutritional intervention during hospitalization (OR, 18.93; 95% CI, 4.48–80.00; P < 0.01). The sensitivity and NPV to predict a LOS ≥ 4 d were respectively 62.6% and 72%, and respectively 94.6% and 98.9% to predict a nutritional intervention.ConclusionsSTRONGkids is an easy-to-use screening tool. Children classified as “low risk” have a 5% probability of being acutely malnourished, with only a 1% probability of a nutritional intervention during hospitalization. 相似文献

In order to evaluate the impact of influenza-like illness and the effectiveness of influenza vaccination in children with oncohematological disease who have completed cancer therapy, 182 children with a diagnosis of oncohematological disease were divided into two subgroups on the basis of the length of time off therapy (<6 months or 6–24 months) and randomised 1:1 to receive influenza vaccination or not. The controls were 91 otherwise healthy children unvaccinated against influenza. The results show that the clinical and socioeconomic impact of influenza-like illnesses and the effectiveness of influenza vaccination in oncohematological children who have completed cancer therapy are related to the length of the off therapy period, and seem to be significantly greater in those who have been off therapy for less than 6 months in comparison with healthy controls. This suggests that the administration of influenza vaccination should be strongly recommended only among oncohematological children who have been off therapy for less than 6 months. 相似文献

Like in most other countries, influenza surveillance in The Netherlands is based upon influenza-like illness (ILI) consultations reported by sentinel general practitioners (GP). In addition, an internet-based monitoring of ILI in the general population started in 2003/2004 (Great Influenza Survey (GIS)). We compared GIS results over 5 influenza seasons with results from the GP system. Weekly ILI incidence from GIS correlated well with ILI incidence from the GP system the same week and even better 1 week later. This suggests that GIS is useful for early detection of trends in influenza activity. However, two important vulnerable groups, children and the elderly, are clearly underrepresented in the GIS. Furthermore, virological confirmation is lacking in the GIS. So, GIS can be a useful addition to the GP system, especially when representativeness can be improved and when participation remains at the current high level. 相似文献
