IntroductionWidespread introduction of pneumococcal conjugated vaccines (PCVs) impacted on invasive pneumococcal disease (IPD). However, IPD reduction may not be similar in all outcomes within IPD.We assessed PCV7/PCV13 impact on pneumococcal meningitis, bacteremic pneumonia (BP) and other (non-meningitis, non-pneumonia) IPD episodes in children <5 years in Israel.MethodsA prospective, population-based, active nationwide surveillance.All pneumococcal invasive episodes with positive blood/CSF cultures, July 2000 through June 2016, were included. Three sub-periods were defined: pre-PCV (2000–2008), PCV7 (2009–2011) and PCV13 (2014–2016). Incidence rate ratios (IRRs) were calculated.ResultsOverall, 4321 episodes were recorded; 456 (10.6%) meningitis, 1478 (34.2%) pneumonia and 2387 (55.2%) other-IPD.In the pre-PCV period, proportion of serotypes in PCV13, but not in PCV7 (mainly serotypes 1, 5 and 19A) was higher in BP (43.3%) compared with other-IPD episodes (32.8%, p < 0.001) and similar to that of meningitis (37.6%, p = 0.1). The proportion of episodes in children <12 months was higher in meningitis (52.1%) compared with pneumonia (23.2%) and other-IPD episodes (39.5%; p < 0.001 for both).The declines of the 3 entities were not similar; Meningitis rate non-significantly declined by 24% (IRR = 0.76; 95% CI 0.57–1.01), while BP and other-IPD rates significantly declined by 57% and 70%, respectively. In contrast to other entities, BP did not decline significantly after PCV7 introduction but started to decline only after PCV13 introduction.Rates of meningitis, pneumonia and other-IPD caused by PCV13-serotypes (VT13) substantially declined by 88%, 95% and 97%, respectively, comparing PCV13 and the pre-PCV periods. However, diseases caused by non-VT13 increased by 256%, 302% in meningitis and pneumonia, respectively, but only 116% in other-IPD.ConclusionsFollowing PCV7/PCV13 introduction, rates of episodes caused by VT13 were substantially reduced in all 3 groups. However, differences in age distribution, serotype replacement and specific serotype decrease suggest different pathogenesis and host susceptibility between the 3 entities. 相似文献

BackgroundAnxiety symptoms may be a barrier to physical activity (PA) such that persons who experience anxiety engage in less PA. The purpose of this study was to assess if symptoms of panic disorder, social phobia, generalized anxiety disorder (GAD) or agoraphobia are associated with frequency, intensity or type of PA in young adults.MethodsData on lifetime anxiety symptoms and current PA levels were collected in self-report questionnaires in 2007–2008 from 880 persons aged 18–24 years participating in the Nicotine Dependence in Teens (NDIT) study. The associations between anxiety symptom subtypes and different PA modalities were investigated in five multivariable logistic regression models, one for each of five PA indicators (i.e., meeting moderate-to vigorous PA (MVPA) guidelines, meeting strength training guidelines, meeting both MVPA and strength training guidelines, participating in team sports, frequent walking) as outcomes.Results37%, 47%, 40% and 21% of participants reported lifetime symptoms of panic disorder, social phobia, GAD, and agoraphobia, respectively. In multivariable logistic regression, participants who endorsed lifetime GAD symptoms were statistically significantly less likely to meet MVPA guidelines (OR 0.5, 95% CI 0.4–0.8, p < 0.05), and MVPA and strength training guidelines (OR 0.7, 95% CI 0.5–1.0, p < 0.05). Those with agoraphobia symptoms were more likely to walk frequently [OR (95% CI) = 1.6 (1.1, 2.3)].ConclusionPA interventions may need to be tailored to people who have experienced specific anxiety symptoms to maximize adherence to PA recommendations, and increase the potential for health benefits from PA participation. 相似文献
