    背景:2014年7月,肯尼亚在其国家免疫计划中引入了一种在6周龄和10周龄口服的单价轮状病毒疫苗。该研究评估了疫苗对肯尼亚全因和轮状病毒特异性急性胃肠炎(AGE)和毒株流行病学住院的长期影响。
    方法:全因和轮状病毒特异性AGE和毒株分布的数据来自2009年至2020年在肯尼亚中部Kiambu县教学和转诊医院(KCTRH)对5岁以下儿童进行的为期11年的基于医院的AGE监测。使用ELISA筛选粪便样品中的A组轮状病毒,并使用多重半巢式RT-PCR进行基因分型。比较了疫苗接种前(2009年7月至2014年6月)的全因和轮状病毒相关AGE和毒株分布的趋势,早期疫苗后(2014年7月至2016年6月)和晚期疫苗后(2019年2月至2020年10月)。
    结果:在疫苗接种前检测到轮状病毒特异性AGE为27.5%(429/1546,95%CI:25.5-30.1%);在疫苗接种后早期(2014年7月至2016年6月)检测到13.8%(91/658,95%CI:11.3-16.6%);在疫苗接种后2月至2019年10月后期检测到12.0%(/1916,在疫苗后早期,轮状病毒特异性AGE下降了49.8%(95%CI:34.6%-63.7%),在疫苗后后期下降了53.4%(95%CI:41.5-70.3%)与疫苗前相比。在疫苗接种后早期和疫苗接种后后期,全因AGE住院率下降了40.2%(95%CI:30.8%-50.2%)和75.3%(95%CI:65.9-83.1%),分别,与疫苗接种前相比。G3P[8]是疫苗后期的优势菌株,替代G1P[8]在疫苗接种前和疫苗接种后早期占主导地位。此外,我们在疫苗接种后检测到相当比例的不常见菌株G3P[6](4.8%)和G12P[6](3.5%).
    结论:轮状病毒疫苗接种导致全因和轮状病毒特异性AGE显著下降,因此,为肯尼亚的公共卫生政策制定者支持在常规免疫中持续使用轮状病毒疫苗提供了强有力的证据。然而,轮状病毒AGE的毒株优势和年龄分布在疫苗接种后时代的转变强调,有必要继续监测,以评估任何可能随时间推移而降低疫苗有效性的疫苗诱导的选择压力.
    BACKGROUND: Kenya introduced a monovalent rotavirus vaccine administered orally at 6 and 10 weeks of age into her National Immunization Program in July 2014. The study evaluated the long-term impact of the vaccine on hospitalization for all-cause and rotavirus-specific acute gastroenteritis (AGE) and strain epidemiology in Kenya.
    METHODS: Data on all-cause and rotavirus-specific AGE and strain distribution were derived from an eleven-year hospital-based surveillance of AGE among children aged <5 years at Kiambu County Teaching and Referral Hospital (KCTRH) in Central Kenya between 2009 and 2020. Fecal samples were screened for group A rotavirus using ELISA and genotyped using multiplex semi-nested RT-PCR. Trends in all-cause and rotavirus-related AGE and strain distribution were compared between the pre-vaccine (July 2009-June 2014), early post-vaccine (July 2014-June 2016) and late post-vaccine (February 2019-October 2020) periods.
    RESULTS: Rotavirus-specific AGE was detected at 27.5% (429/1546, 95% CI: 25.5-30.1%) in the pre-vaccine period; 13.8% (91/658, 95% CI: 11.3-16.6%) in the early post-vaccine period (July 2014-June 2016); and 12.0% (229/1916, 95% CI: 10.6-13.5%) in the late post-vaccine period (February 2019-October 2020). This amounted to a decline of 49.8% (95% CI: 34.6%-63.7%) in rotavirus-specific AGE in the early post-vaccine period and 53.4% (95% CI: 41.5-70.3%) in the late post-vaccine period when compared to the pre-vaccine period. All-cause AGE hospitalizations declined by 40.2% (95% CI: 30.8%-50.2%) and 75.3% (95% CI: 65.9-83.1%) in the early post-vaccine and late post-vaccine periods, respectively, when compared to the pre-vaccine period. G3P [8] was the predominant strain in the late post-vaccine period, replacing G1P[8] which had predominated in the pre-vaccine and early post-vaccine periods. Additionally, we detected considerable proportions of uncommon strains G3P[6] (4.8%) and G12P[6] (3.5%) in the post-vaccine era.
    CONCLUSIONS: Rotavirus vaccination has resulted in a significant decline in all-cause and rotavirus-specific AGE, and thus, provides strong evidence for public health policy makers in Kenya to support the sustained use of the rotavirus vaccine in routine immunization. However, the shift in strain dominance and age distribution of rotavirus AGE in the post-vaccine era underscores the need for continued surveillance to assess any possible vaccine-induced selective pressure that could diminish the vaccine effectiveness over time.

    物联网(IoT)的快速发展广泛地推动了无线传感器网络(WSNs)的发展,用于显示从物理世界收集的感知和数据的系列的基本技术。在密集分布的地区,传感器节点分布不均匀,这导致了网络覆盖的建立以及随之而来的WSN的效率和有效性。为了解决这个问题,提出了一种基于爬行动物搜索算法(RSA)的无线传感器网络覆盖优化方法。在过去,爬行动物搜索算法已用于解决优化问题,这意味着它可以改进不同的过程。然而,RSA需要跟踪每次迭代中最优个体的轨迹,这将忽略非最优个体的生物经济特征。因此,本文将分布估计策略引入到RSA框架中,它可以充分挖掘隐藏在整个人群中的所有位置信息。我们选择了几个函数作为优化测试基准函数来评估所提出方法的可行性。本文将提出的改进RSA与标准RSA和一些传统的优化算法进行了比较。通过一系列网络覆盖优化实验,参数的变化也决定了RSA在网络覆盖优化中的作用。3个相似网络覆盖优化实验的仿真结果表明,改进的RSA在不同场景下都能有效使用。
    The rapid development of the Internet of Things (IoT) has extensively promoted the development of Wireless Sensor Networks (WSNs), an essential technology for series displaying perception and data collected from the physical world. In densely distributed areas, sensor nodes are unevenly distributed, which leads to the network coverage build-up and the consequent efficiency and effectiveness of WSNs. To address this issue, this paper proposes a new method for WSN coverage optimization based on the Reptile Search Algorithm (RSA). In the past, the Reptile Search algorithm has been used to solve optimization problems, which means it can improve different processes. However, the RSA needs to track the trajectory of optimal individuals in each iteration, which will ignore non-optimal individuals\' bioeconomic characteristics. Therefore, the paper introduces a distribution estimation strategy into the RSA framework, which can fully mine all the positional information hidden in the entire population. We selected several functions as optimization test benchmark functions to evaluate the feasibility of the proposed method. This paper compares the proposed improved RSA with the standard RSA and some traditional optimization algorithms. The result has been calculated through a series of experiments on network coverage optimization, and the change of parameters also determines the effect of the RSA in the optimization of network coverage. The simulated results of the three similar network coverage optimization experiments show that the improved RSA can be used efficiently within different scenarios.

    边境监测和关键基础设施监测是区域和工业安全的重要组成部分。在本文中,我们的目的是研究利用泛倾斜变焦(PTZ)摄像机的混合监测系统使用的监测方法的复杂性,建模为定向传感器,和无人机。我们的目标是实现三个有时相互冲突的目标。首先,在任何给定时刻,我们都希望发现尽可能多的入侵者,并特别注意新到达的入侵者。其次,我们认为尽可能准确地观察每个入侵者组的时间运动和行为同样重要。此外,除了这些目标,我们还寻求将与监视相关的传感器使用成本降至最低。在研究过程中,我们开发和分析了几个相互关联的,越来越复杂的算法。通过利用RL方法,我们还为系统提供了自己找到最佳解决方案的机会。因此,我们获得了有关这些算法的各个组成部分如何相互联系和协调的宝贵见解。基于这些观察,我们设法开发了一种有效的算法,该算法考虑了上述所有三个标准。
    Border surveillance and the monitoring of critical infrastructure are essential components of regional and industrial security. In this paper, our purpose is to study the intricate nature of surveillance methods used by hybrid monitoring systems utilizing Pan-Tilt-Zoom (PTZ) cameras, modeled as directional sensors, and UAVs. We aim to accomplish three occasionally conflicting goals. Firstly, at any given moment we want to detect as many intruders as possible with special attention to newly arriving trespassers. Secondly, we consider it equally important to observe the temporal movement and behavior of each intruder group as accurately as possible. Furthermore, in addition to these objectives, we also seek to minimize the cost of sensor usage associated with surveillance. During the research, we developed and analyzed several interrelated, increasingly complex algorithms. By leveraging RL methods we also gave the system the chance to find the optimal solution on its own. As a result we have gained valuable insights into how various components of these algorithms are interconnected and coordinate. Building upon these observations, we managed to develop an efficient algorithm that takes into account all three criteria mentioned above.

    背景:在低收入和中等收入国家,产妇发病率和死亡率居高不下,尽管设施交付的覆盖面和交付时的熟练援助有所增加。我们将设施出生水平与简易分娩护理措施和量化差距进行了比较。
    方法:我们从分娩类型(家庭,较低级别的设施,或医院),交付时熟练的服务员,交货后24小时或更长时间的逗留,分娩后48小时内进行健康检查。数据来自33,316名15-49岁的女性,她们在过去2年内有活产,并在2013年至2020年期间对71个国家进行了具有全国代表性的调查。我们计算了设施交付和交付护理覆盖率估计来评估差距。我们按国家特征对分析进行了分层,包括全国孕产妇死亡率(MMR),为了评估覆盖差距的大小,我们通过覆盖级联评估错过的机会。我们研究了MMR和分娩护理保险之间的关联。
    结果:分娩护理覆盖率因国家而异,从苏丹的24%到古巴的100%不等。平均覆盖率为70%,四分位数范围为30个百分点(55%和85%)。级联显示,虽然76%的女性在医院分娩,只有41%的人接受了所有四种干预措施.所有MMR级别都存在覆盖差距。最高和最低财富五分位数之间的差距在MMR水平为100或更高的国家中最大,在MMR水平低于100的国家,差距缩小了。分娩护理指标与MMR呈负相关。
    结论:除了在分娩和产后期间为妇女提供高质量的循证护理外,还需要解决分娩护理方面的差距,发生在国家内部和国家之间,财富五分位数,MMR阶段。
    BACKGROUND: High levels of maternal morbidity and mortality persist in low- and middle-income countries, despite increases in coverage of facility delivery and skilled assistance at delivery. We compared levels of facility birth to a summary delivery care measure and quantified gaps.
    METHODS: We approximated a delivery care score from type of delivery (home, lower-level facility, or hospital), skilled attendant at delivery, a stay of 24-or-more-hours after delivery, and a health check within 48-h after delivery. Data were obtained from 333,316 women aged 15-49 who had a live birth in the previous 2 years, and from 71 countries with nationally representative surveys between 2013 and 2020. We computed facility delivery and delivery care coverage estimates to assess the gap. We stratified the analysis by country characteristics, including the national maternal mortality ratio (MMR), to assess the size of coverage gaps, and we assessed missed opportunities through coverage cascades. We looked at the association between MMR and delivery care coverage.
    RESULTS: Delivery care coverage varied by country, ranging from 24% in Sudan to 100% in Cuba. Median coverage was 70% with an interquartile range of 30 percentage points (55% and 85%). The cascade showed that while 76% of women delivered in a facility, only 41% received all four interventions. Coverage gaps exist across all MMR levels. Gaps between highest and lowest wealth quintiles were greatest in countries with MMR levels of 100 or higher, and the gap narrowed in countries with MMR levels below 100. The delivery care indicator had a negative association with MMR.
    CONCLUSIONS: In addition to providing high-quality evidenced-based care to women during birth and the postpartum period, there is also a need to address gaps in delivery care, which occur within and between countries, wealth quintiles, and MMR phases.

    目的:美国商业健康计划覆盖政策的变化会影响患者获得药物的方式。计划在治疗准入标准方面可能有所不同,线的治疗,和开药者的要求。在这项研究中,我们检查了盐酸艾氯胺酮(Spravato)对重度抑郁症(MDD)和难治性抑郁症(TRD)的覆盖范围,以回答以下问题:美国商业健康计划如何涵盖艾氯胺酮,
    方法:我们使用了塔夫茨医学中心专业药物证据和承保数据库中的信息,其中包括美国18个大型商业健康计划发布的覆盖政策。对2022年12月活跃的MDD和TRD的Esketamine覆盖政策进行了整理和分析。我们根据阶梯治疗方案比较了承保政策,患者亚组限制,和开药者要求标准,使用包括每个标准的限制数量和计划比例来评估患者的访问。
    结果:与MDD相比,TRD更经常对使用esketamine的计划施加阶梯治疗要求,MDD的治疗线≤9个步骤,而TRD的治疗线为1至5个步骤。关于他们要求患者在获得这两种适应症之前首先尝试并经历治疗失败的疗法,计划也有所不同。用于评估抑郁症状严重程度的阈值和评级量表的临床覆盖率要求各不相同。
    结论:计划在获得艾氯胺酮的治疗方案和临床覆盖要求方面有所不同。健康计划覆盖政策的变化可能会导致患者和临床医生在护理中的获取不公平和复杂性增加。这可能会延迟获得紧急治疗。
    结果:
    不适用。
    OBJECTIVE: Variations in US commercial health plan coverage policies affect how patients access medications. Plans may vary in treatment access criteria, line of therapy, and prescriber requirements. In this study, we examined coverage of esketamine hydrochloride (Spravato) for major depressive disorder (MDD) and treatment-resistant depression (TRD) to answer the following question: how do US commercial health plans cover esketamine, and how do they guide prompt patient access to the drug?
    METHODS: We used information from the Tufts Medical Center Specialty Drug Evidence and Coverage database, which includes coverage policies issued by 18 large commercial health plans in the United States. Esketamine coverage policies for MDD and TRD active in December 2022 were collated and analyzed. We compared coverage policies according to step therapy protocols, patient subgroup restrictions, and prescriber requirement criteria, evaluating patient access using the number of restrictions and proportion of plans including each criterion.
    RESULTS: Plans more often imposed step therapy requirements for access to esketamine for TRD than for MDD, with line of treatment of ≤9 steps for MDD compared with 1 to 5 steps for TRD. Plans also varied with respect to the therapies they required patients to first try and experience treatment failure before granting access to esketamine for both indications. Clinical coverage requirements varied in thresholds and rating scales used to assess severity of depressive symptoms.
    CONCLUSIONS: Plans vary in terms of line of therapy and clinical coverage requirements for access to esketamine. Variation in health plan coverage policies may result in inequitable access and added complexity for patients and clinicians navigating care, which may delay access to urgent treatment.
    RESULTS:
    UNASSIGNED: Not applicable.

    尽管有证据表明产前护理(ANC)服务质量差,在对每次ANC访问的人口水平以及ANC服务来源的质量调整覆盖率的理解方面仍然存在显着差距,在这个覆盖范围内也是公平的。
    2020年7月至2021年6月之间的所有出生都来自比哈尔邦的261,124户家庭(91.5%的参与率)。所有死产和新生儿死亡的母亲,在新生儿期存活的25%的活产随机样本中,提供了每次ANC就诊的数据,最多可进行前4次ANC就诊,包括ANC服务的来源和接收的服务(重量测量,检查血压,腹部检查,采集尿液样本,和采集的血液样本)。如果在该访问中收到所有这些服务,则认为ANC访问是高质量的。我们报告了按ANC服务来源和财富指数(WI)分类的ANC访问1-4的质量调整后的ANC服务(Q-ANC)的覆盖率。报告加权比例以考虑取样设计。
    29,517名妇女报告了30,412例分娩,8853名合格妇女中有7270人(82.1%)参加。总的来说,来自6929名妇女的19,950次独特的ANC访问可供分析,其中41.7%,13.8%和44.5%在乡村健康和营养日(VNHD),公共设施,和一个私人提供者,分别。VHND共进行了4409次(65.3%)的第一次ANC访问,从ANC访视1到ANC访视4,私人提供者的ANC访视比例显着增加(p<0.001)。考虑到所有ANC访问,Q-ANC覆盖率为20.9%(95%CI20.7-21.2);为0.9%(95%CI0.8-1.0),VHND中ANC就诊的29.9%(95%CI29.2-30.7)和36.9%(95%CI36.5-37.4),公共设施,和私人提供者,分别。与第1至3次就诊相比,第4次ANC就诊时,公共设施中的Q-ANC覆盖率明显较低(25.1%;95%CI23.4-26.9),而与私人提供者的第1次ANC就诊时最高(50.2%;95%CI49.2-51.1),然后在第2至4次就诊时下降。无论ANC服务的来源如何,Q-ANC覆盖率随着ANC访问1和2的WI四分位数的增加而显着增加,WI四分位数3的女性与其他女性相比,ANC访问3的覆盖率明显较少,在ANC4访问的覆盖率中没有显着差异。对于公共设施和私人提供者的访问,可以看到WI对每次ANC访问的Q-ANC覆盖的不同模式。
    在10次ANC访问中只有2次被认为质量足够,无论妊娠期如何,每位孕妇都需要持续提供优质的ANC服务,ANC访问次数,和ANC服务的来源。

    UNASSIGNED: Despite the evidence on the poor quality of antenatal care (ANC) services, significant gap remains in the understanding of quality-adjusted coverage at the population-level for each ANC visit and by the source of ANC services, and in equity in this coverage.
    UNASSIGNED: All births between July 2020 and June 2021 were listed from 261,124 households (91.5% participation) representative of the Bihar state. Mothers of all stillbirths and neonatal deaths, and of 25% random sample of livebirths who survived the neonatal period provided data on each ANC visit up to a maximum of first 4 ANC visits, including the source of ANC services and the services received (weight measurement, blood pressure checked, abdomen checked, urine sample taken, and blood sample taken). An ANC visit was deemed of quality if all of these services were received in that visit. We report the coverage of quality-adjusted ANC services (Q-ANC) for ANC visits 1-4 disaggregated by source of ANC services and wealth index (WI). Weighted proportions are reported to take into account the sampling design.
    UNASSIGNED: A total of 30,412 births were reported by 29,517 women, and 7270 (82.1%) of the 8853 eligible women participated. Overall, 19,950 unique ANC visits from 6929 women were available for analysis, of which 41.7%, 13.8% and 44.5% were at Village Health and Nutrition Day (VNHD), public facility, and with a private provider, respectively. A total of 4409 (65.3%) of the 1st ANC visits were undertaken at VHND, with the proportion of private provider ANC visits increasing significantly from ANC visit 1 to ANC visit 4 (p < 0.001). Q-ANC coverage considering all ANC visits was 20.9% (95% CI 20.7-21.2); and was 0.9% (95% CI 0.8-1.0), 29.9% (95% CI 29.2-30.7) and 36.9% (95% CI 36.5-37.4) for ANC visits in VHND, public facilities, and with private provider, respectively. Q-ANC coverage in the public facility was significantly lower in the 4th ANC visit (25.1%; 95% CI 23.4-26.9) as compared with visits 1 to 3, whereas it was the highest for 1st ANC visit with private provider (50.2%; 95% CI 49.2-51.1) and then dropped for visits 2 to 4. Irrespective of the source of ANC services, Q-ANC coverage increased significantly with increasing WI quartile for ANC visits 1 and 2, with WI quartile 3 women having significantly less coverage for ANC visit 3 compared to the rest, and no significant difference seen in the coverage of ANC 4 visit. Varied pattern of Q-ANC coverage by WI for each ANC visit was seen for public facility and private provider visits.
    UNASSIGNED: With only 2 of 10 ANC visits deemed of adequate quality, sustainable delivery of quality ANC services are needed for every pregnant woman through-out the pregnancy irrespective of gestation period, number of ANC visit, and source of ANC services.
    UNASSIGNED: The funding was provided by the India office of the Bill & Melinda Gates Foundation, USA.

    界面电场在确定电催化过程中的极性分子构型和表面覆盖率方面具有重要意义。本研究介绍了一种在不同的界面电场强度下利用SO2变化的电偶极矩来增强SO2电还原过程的选择性的方法。这种方法首次尝试利用向Au/PTFE膜电极施加脉冲电压来控制电极表面上SO2的分子构型和覆盖率。值得注意的是,在毫秒脉冲条件下(ta=10ms,tc=300ms,Ea=-0.8V(相对于Hg/Hg2SO4),Ec=-1.8V(相对于Hg/Hg2SO4),伴随着H2S选择性的显著提高(FEH2S>97%)。综合分析,结合原位拉曼光谱,电化学石英晶体微天平,COMSOL模拟,和DFT计算,证实了H2S产物选择性的增加主要与SO2分子固有的大偶极矩有关。毫秒脉冲引起的界面电场的增强有助于放大SO2覆盖率,活化SO2,促进关键中间产物*SOH的形成,有效降低SO2还原过程中的反应能障。这些发现为离子和分子传输动力学的影响提供了新的见解,以及SO2电还原过程中竞争途径的时间复杂性。此外,它强调了电偶极矩与催化剂的表面-分子相互作用之间的内在相关性。
    Interfacial electric field holds significant importance in determining both the polar molecular configuration and surface coverage during electrocatalysis. This study introduces a methodology leveraging the varying electric dipole moment of SO2 under distinct interfacial electric field strengths to enhance the selectivity of the SO2 electroreduction process. This approach presented the first attempt to utilize pulsed voltage application to the Au/PTFE membrane electrode for the control of the molecular configuration and coverage of SO2 on the electrode surface. Remarkably, the modulation of pulse duration resulted in a substantial inhibition of the hydrogen evolution reaction (HER) (FEH2 < 3%) under millisecond pulse conditions (ta = 10 ms, tc = 300 ms, Ea = -0.8 V (vs Hg/Hg2SO4), Ec = -1.8 V (vs Hg/Hg2SO4)), concomitant with a noteworthy enhancement in H2S selectivity (FEH2S > 97%). A comprehensive analysis, incorporating in situ Raman spectroscopy, electrochemical quartz crystal microbalance, COMSOL simulations, and DFT calculations, corroborated the increased selectivity of H2S products was primarily associated with the inherently large dipole moment of the SO2 molecule. The enhancement of the interfacial electric field induced by millisecond pulses was instrumental in amplifying SO2 coverage, activating SO2, facilitating the formation of the pivotal intermediate product *SOH, and effectively reducing the reaction energy barrier in the SO2 reduction process. These findings provide novel insights into the influences of ion and molecular transport dynamics, as well as the temporal intricacies of competitive pathways during the SO2 electroreduction process. Moreover, it underscores the intrinsic correlation between the electric dipole moment and surface-molecule interaction of the catalyst.

    2020-21年,在COVID-19大流行期间,在宁波的老年居民中启动了免费的流感疫苗接种计划,中国。需要评估COVID-19大流行和免费疫苗接种政策对流感疫苗摄取的影响。12月31日之前出生的人的流感疫苗摄取,1962年宁波从2017-18到2022-23赛季进行了分析。多变量逻辑回归用于估计COVID-19大流行和免费疫苗接种政策的影响。我们的分析包括平均每年1,856,565个人。流感疫苗接种覆盖率从2017-18年的1.14%上升至2022-23年的33.41%。2022-23年免费政策目标人群疫苗接种覆盖率为50.03%。多因素分析显示,免费疫苗接种政策增加流感疫苗接种量最大(OR=11.99,95CI:11.87~12.11)。大流行的初始阶段与对流感疫苗接种的积极影响有关(OR=2.09,95CI:2.07-2.12),但在随后的两季中出现负效应(2021-22年:OR=0.75,95CI:0.73-0.76;2022-23年:OR=0.40,95CI:0.39-0.40)。当前季节的COVID-19疫苗接种是流感疫苗摄取的阳性预测因子,而在2022-23年之前未完成加强COVID-19疫苗接种是阴性预测因子。在上一个季节期间具有流感疫苗史和具有ILI病史也是流感疫苗摄取的阳性预测因子。免费疫苗接种政策提高了老年人群的流感疫苗接种覆盖率。COVID-19大流行在不同季节发挥不同的作用。我们的研究强调了如何针对疫苗接种覆盖率低的弱势群体实施免费疫苗接种政策的必要性。
    In 2020-21, during the COVID-19 pandemic, a free influenza vaccination program was initiated among the elderly residents in Ningbo, China. The impact of the COVID-19 pandemic and free vaccination policy on influenza vaccine uptake needs to be evaluated. The influenza vaccine uptake among individuals born before 31 December, 1962 from 2017-18 to 2022-23 season in Ningbo was analyzed. Multivariate logistic regressions were used to estimate the impact of the COVID-19 pandemic and free vaccination policy. Our analysis included an average of 1,856,565 individuals each year. Influenza vaccination coverage increased from 1.14% in 2017-18 to 33.41% in 2022-23. The vaccination coverage among the free policy target population was 50.03% in 2022-23. Multivariate analysis showed that free vaccination policy increased influenza vaccine uptake most (OR = 11.99, 95%CI: 11.87-12.11). The initial phase of the pandemic was associated with a positive effect on influenza vaccination (OR = 2.09, 95%CI: 2.07-2.12), but followed by a negative effect in the subsequent two seasons(2021-22: OR = 0.75, 95%CI: 0.73-0.76; 2022-23: OR = 0.40, 95%CI: 0.39-0.40). COVID-19 vaccination in the current season was a positive predictor of influenza vaccine uptake while not completing booster COVID-19 vaccination before was negative predictor in 2022-23. Having influenza vaccine history and having ILI medical history during the last season were also positive predictors of influenza vaccine uptake. Free vaccination policies have enhanced influenza vaccination coverage among elderly population. The COVID-19 pandemic plays different roles in different seasons. Our study highlights the need for how to implement free vaccination policies targeting vulnerable groups with low vaccination coverage.

  • 文章类型: Systematic Review
    背景:这篇综述的目的是调查基于短信服务(SMS)的干预措施对儿童和青少年疫苗覆盖率和及时性的影响。
    方法:使用预定义的搜索策略从电子数据库中识别直到2022年7月的所有相关出版物。包括以英语撰写的随机试验报告,涉及18岁以下的儿童和青少年。审查是根据PRISMA指南进行的。
    结果:确定了30项随机试验。大多数试验是在高收入国家进行的。研究之间存在明显的异质性。与没有短信提醒相比,基于短信的干预措施与疫苗覆盖率和及时性的小到中等改善相关。在某些情况下,具有嵌入式教育或与金钱激励相结合的提醒比简单的提醒表现更好。
    结论:在某些情况下,一些基于SMS的干预措施对于提高儿童疫苗覆盖率和及时性似乎是有效的。未来的研究应该集中在确定基于短信的策略的哪些特征,包括消息内容和时间,是有效性的决定因素。
    BACKGROUND: The aim of this review was to investigate the impact of short message service (SMS)-based interventions on childhood and adolescent vaccine coverage and timeliness.
    METHODS: A pre-defined search strategy was used to identify all relevant publications up until July 2022 from electronic databases. Reports of randomised trials written in English and involving children and adolescents less than 18 years old were included. The review was conducted in accordance with PRISMA guidelines.
    RESULTS: Thirty randomised trials were identified. Most trials were conducted in high-income countries. There was marked heterogeneity between studies. SMS-based interventions were associated with small to moderate improvements in vaccine coverage and timeliness compared to no SMS reminder. Reminders with embedded education or which were combined with monetary incentives performed better than simple reminders in some settings.
    CONCLUSIONS: Some SMS-based interventions appear effective for improving child vaccine coverage and timeliness in some settings. Future studies should focus on identifying which features of SMS-based strategies, including the message content and timing, are determinants of effectiveness.
