BackgroundThe COVID-19 pandemic expanded the need for timely information on acute respiratory illness at population level.AimWe explored the potential of routine emergency department data for syndromic surveillance of acute respiratory illness in Germany.MethodsWe used routine attendance data from emergency departments, which continuously transferred data between week 10 2017 and 10 2021, with ICD-10 codes available for > 75% of attendances. Case definitions for acute respiratory infection (ARI), severe acute respiratory infection (SARI), influenza-like illness (ILI), respiratory syncytial virus infection (RSV) and COVID-19 were based on a combination of ICD-10 codes, and/or chief complaints, sometimes combined with information on hospitalisation and age.ResultsWe included 1,372,958 attendances from eight emergency departments. The number of attendances dropped in March 2020 during the first COVID-19 pandemic wave, increased during summer, and declined again during the resurge of COVID-19 cases in autumn and winter of 2020/21. A pattern of seasonality of respiratory infections could be observed. By using different case definitions (i.e. for ARI, SARI, ILI, RSV) both the annual influenza seasons in the years 2017–2020 and the dynamics of the COVID-19 pandemic in 2020/21 were apparent. The absence of the 2020/21 influenza season was visible, parallel to the resurge of COVID-19 cases. SARI among ARI cases peaked in April–May 2020 (17%) and November 2020–January 2021 (14%).ConclusionSyndromic surveillance using routine emergency department data can potentially be used to monitor the trends, timing, duration, magnitude and severity of illness caused by respiratory viruses, including both influenza viruses and SARS-CoV-2.  相似文献

It is unclear why some children develop food allergy. The EuroPrevall birth cohort was established to examine regional differences in the prevalence and risk factors of food allergy in European children using gold-standard diagnostic criteria. The aim of this report was to describe pre-, post-natal and environmental characteristics among the participating countries. In nine countries across four major European climatic regions, mothers and their newborns were enrolled from October 2005 through February 2010. Using standardized questionnaires, we assessed allergic diseases and self-reported food hypersensitivity of parents and siblings, nutrition during pregnancy, nutritional supplements, medications, mode of delivery, socio-demographic data and home environmental exposures. A total of 12,049 babies and their families were recruited. Self-reported adverse reactions to food ever were considerably more common in mothers from Germany (30%), Iceland, United Kingdom, and the Netherlands (all 20-22%) compared with those from Italy (11%), Lithuania, Greece, Poland, and Spain (all 5-8%). Prevalence estimates of parental asthma, allergic rhinitis and eczema were highest in north-west (Iceland, UK), followed by west (Germany, the Netherlands), south (Greece, Italy, Spain) and lowest in central and east Europe (Poland, Lithuania). Over 17% of Spanish and Greek children were exposed to tobacco smoke in utero compared with only 8-11% in other countries. Caesarean section rate was highest in Greece (44%) and lowest in Spain (<3%). We found country-specific differences in antibiotic use, pet ownership, type of flooring and baby's mattress. In the EuroPrevall birth cohort study, the largest study using gold-standard diagnostic criteria for food allergy in children worldwide, we found considerable country-specific baseline differences regarding a wide range of factors that are hypothesized to play a role in the development of food allergy including allergic family history, obstetrical practices, pre- and post-natal environmental exposures.  相似文献

Background

Chronic noise is an environmental pollutant and well-known to cause annoyance and sleep disturbance. Its association with clinical and subclinical adverse health effects has been discussed.

Objectives

This systematic review aimed to examine associations between chronic noise exposure during pregnancy or childhood and health outcomes in early and late childhood.

Methods

Following a systematic electronic literature search (MEDLINE, EMBASE), an additional hand search and a critical evaluation of potential articles by 2 independent reviewers, 29 studies were included: 12 on pregnancy/birth outcomes with samples ranging from 115 to 22,761 and 17 on cardiovascular and immune-mediated health outcomes in childhood with samples ranging from 43 to 1542. Evidence levels (3 to 2++) were rated according to the Scottish Intercollegiate Guidelines Network.

Results

Chronic noise exposure during pregnancy was not associated with birth weight, preterm birth, congenital anomalies, perinatal and neonatal death based on 6 cohort, 4 case–control, and 2 cross-sectional studies (highest evidence level 2+). There was some evidence supporting an association of chronic noise exposure with increased systolic blood pressure and stress hormone levels in urine and saliva in children evaluating 2 cohort and 15 cross-sectional studies (highest evidence level 2−).

Conclusions

There seemed to be no associations between chronic noise and pregnancy outcomes based on studies with evidence levels up to 2+. Associations between chronic noise and health in children were based mainly on cross-sectional studies. However, the studies included in this comprehensive systematic review showed a high variation in study design, outcome, exposure and confounder assessments.  相似文献
