Vasovagal reactions after COVID-19 vaccination in Japan

Coronavirus disease 2019 (COVID-19) vaccine administration started in February 2021 in Japan. As of December 2021, approximately 75% of the population aged ≥12 years had received two doses of vaccine. We conducted a study to investigate vasovagal reactions (VVR) after COVID-19 vaccination using data on adverse events following immunization. The crude reporting rate of VVR (cases/1,000,000 doses) after vaccination was 9.6 in all age groups combined, and was more frequent in the younger age groups: 28.6 and 37.2 in individuals aged 10–19 years and 20–29 years, respectively. In individuals aged 10–29 years, the rate was similar in males and females (33.0 and 34.2, respectively, p = 0.53); but was higher after dose 1 than after dose 2 (57.4 and 8.8, respectively, p < 0.001). Based on these results, caution needs to be exercised when vaccinating adolescents and young adults, especially with dose 1 of COVID-19 vaccines.     

Comparison between Antegrade versus Retrograde Ureteral Stent Placement for Malignant Ureteral Obstruction

PurposeTo compare the technical success of antegrade uteral stent (AUS) and retrograde ureteral stent (RUS) placements in patients with malignant ureteral obstruction (MUO) and to determine the predictors of technical failure of RUS.Materials and MethodsThis study retrospectively included 61 AUS placements (44 patients) performed under fluoroscopic guidance and 76 RUS placements (55 patients) performed under cystoscopic guidance in patients with MUO from January 2019 to December 2020. Technical success rates of the 2 techniques were compared using inverse probability of treatment weighting (IPTW) analysis. Logistic regression was used to identify predictive factors for technical failures.ResultsTechnical success was achieved in 98.4% of the AUS group and 47.4% of the RUS group. After stabilized IPTW, the technical success rate was higher in the AUS group than in the RUS group (adjusted risk difference, 49.4%; 95% confidence interval [CI], 35.4%–63.1%). The independent predictors for technical failure of the RUS procedure were age of ≥65 years (odds ratio [OR], 5.56; 95% CI, 1.73–21.27), ureteral orifice invasion (OR, 4.21; 95% CI, 1.46–13.46), and extrinsic cancer (OR, 15.58; 95% CI, 2.92–111.81).ConclusionsThe technical success rate of AUS placement was higher than that of RUS placement in patients with MUO. RUS failure was associated with age of ≥65 years, cancer with ureteral orifice invasion, and extrinsic ureteral obstruction.     

Enhancing adherence and management in patients with hypertension: Impact of form and frequency of knowledge intervention

BackgroundThe alarming rise in prevalence of hypertension warrants psychosocial methods supplementing pharmacotherapy for better management and prevention of cardiac emergencies. The objective of the study was to assess the differential impact of the form and frequency of knowledge intervention on management of primary hypertension.Materials and methodThe study was conducted on 256 hypertensive patients recruited through purposive sampling at health centers in Hyderabad, India. Pretest post-test control group quasi-experimental design was adopted for the study. There were two forms of the knowledge intervention, namely ‘Direct Interaction’ and ‘Audio-Visual’. Each form was presented in two frequencies namely ‘single exposure’ and ‘double exposure’. The four groups were labelled as Direct Intervention Single (DIS), Direct Intervention Double (DID), Audio-Visual Single (AVS) and Audio-Visual Double (AVD). Adherence and management of hypertension were assessed at baseline and six weeks post experiment. Analysis of Covariance (ANCOVA) was applied using IBM SPSS Statistics version 20.ResultsANCOVA followed by Bonferroni Multiple Group Comparison Test revealed significant differences between the four intervention groups and control group on adherence (p< .001). In case of hypertension management significant differences were observed between Control group and DIS, DID (p < .001), Control and AVS (p < .01). Control group did not differ from AVD.ConclusionThere was a positive impact of Knowledge Intervention on adherence and management of hypertension. Double exposure in audio visual form was counterproductive in hypertension management.     

单孔加一孔联合ERAS在高位直肠及乙状结肠癌中的应用

目的 探讨单孔加一孔腹腔镜手术联合 ERAS 治疗高位直肠及乙状结肠癌的近期疗效。方法 回顾性分析 2017 年 11 月至2018 年 10 月在福建省肿瘤医院胃肠肿瘤外科进行加速康复外科干预的 92 例高位直肠及乙状结肠癌患者资料，根 据手术方式的不同，分为单孔加一孔手术联合快速康复外科组39 例及常规腹腔镜手术联合ERAS 组 53 例，对比两组围术 期情况。结果 两组患者基线资料无明显统计学差异（P ＞ 0.05），且在手术时间、出血量、上下切缘、清扫淋巴结数量及 并发症方面无明显统计学差异（P ＞ 0.05）。但单孔加一孔手术联合ERAS 组较常规手术联合ERAS 组，总切口长度更短 [（6.7±1.1）cm 比（8.5±1.3）cm，P=0.000]，术后首次下床时间更早 [（22.2±5.2）h 比（27.1±7.9）h，P=0.001]，首次排便 时间更早[（70.2±19.8）h比（83.1±20.4）h，P=0.005]，术后第一天C反应蛋白值更低[（43.5±28.6）mg/L比（57.2±33.2） mg/L，P=0.038]，术后住院时间更短 [（7.0±1.7）d 比（8.1±2.1）d，P=0.010]，且术后 2~4 天疼痛评分更低（P ＜ 0.05）。 结论 经验丰富的腔镜医师采用单孔加一孔手术治疗高位直肠及乙状结肠癌并联合 ERAS 干预是安全可行的，且单孔加一孔 手术可减低操作难度，具有疼痛轻、术后恢复快等优势，值得临床推广。

目的 探讨食管癌患者放化疗期间自我效能感与领悟社会支持状况及其相关性。方法 选择2017 年 1~5 月首都 医科大学附属北京康复医院口腔科收治的 216 名食管癌住院患者，应用一般自我效能感量表、领悟社会支持量表和一般资 料调查表进行调查。结果 食管癌患者在放化疗期间自我效能感总体得分为（25.94±5.28）分；其中年龄＞35 岁、月收入 在 5000 元以上、有医保、诊断年限在6~10 年、有治疗史的患者自我效能感水平较高（P ＜ 0.05）。领悟社会支持总分为 （61.67±10.86）分，家庭内支持得分为（23.46±3.91）分，家庭外支持得分为（38.09±8.90）分；其中年龄越大、民族为少 数民族、文化程度越高、居住在城市、职业为医务人员、月收入在 5000 元以上、有医保、确诊年限在 6 年以下的患者领悟 社会支持水平较高（P＜0.05）。患者自我效能感得分与领悟社会支持总分及各维度均呈显著正相关（P＜0.01）。另外， 本研究还发现，完全缓解、部分缓解者的自我效能感、领悟社会支持得分、家庭内支持及家庭外支持得分均显著高于部分稳定、 疾病进展者，差异之间存在统计学意义（P＜0.05）。结论 食管癌患者在放化疗期间自我效能感和领悟社会支持水平较高， 患者感知到的社会支持越高，自我效能感越高。同时，自我效能感和领悟社会支持水平对判断该人群的预后具有重要的临 床意义。     

Pneumococcal meningitis before the introduction of 10-valent pneumococcal conjugate vaccine into the National Childhood Immunization Program in Poland

Background

Poland introduced the 10-valent conjugate pneumococcal vaccine (PCV10) into the childhood immunization program in January 2017. During previous decades, considerable changes had occurred in the surveillance system for invasive pneumococcal disease. Therefore, to provide baseline data on pneumococcal diseases before PCV10 introduction, we evaluated the epidemiology of pneumococcal meningitis (PM), the only syndrome monitored consistently since 1970.

孟鲁司特治疗呼吸道合胞病毒毛细支气管炎症状及反复喘息疗效研究

背景　呼吸道合胞病毒（RSV）毛细支气管炎易出现反复喘息，且下呼吸道分泌物中半胱氨酸白三烯（CysLTs）水平升高。而孟鲁司特是一种白三烯受体拮抗剂，关于其治疗RSV毛细支气管炎症状的研究相对较少。目的　探讨孟鲁司特改善婴幼儿RSV毛细支气管炎后症状及减轻反复喘息发作的有效性和安全性。方法　2015年6月-2017年6月连续纳入在潍坊市妇幼保健院出院的RSV毛细支气管炎患儿，随机分为治疗组、对照组。Ⅰ期，治疗组：口服孟鲁司特颗粒（4 mg）12周，1次/d；对照组：口服安慰剂12周，1次/d。对两组无症状天数、个人日记评分进行评估。随访9个月（Ⅱ期），观察Ⅰ+Ⅱ期反复喘息人数和医疗资源应用情况等。依据意向性分析（ITT）原则，应用全分析集（FAS）分析数据。结果　共纳入研究对象186例，治疗组92例，对照组94例。治疗组完成Ⅰ期研究的患儿为89例，对照组为90例；治疗组完成Ⅰ+Ⅱ期的患儿为84例，对照组为86例。治疗组平均依从性为97.8%（7 560/7 728），对照组平均依从性为97.4%（7 690/7 896），两组患儿平均依从性比较，差异无统计学意义（χ2=3.16，P=0.07）。在Ⅰ期研究期间，两组无症状天数、日间无症状天数、夜间无症状天数、个人日记评分比较，差异均无统计学意义（P>0.05）。在整个研究过程中（Ⅰ+Ⅱ期），治疗组RSV毛细支气管炎喘息复发人数少于对照组（P<0.05），治疗组喘息患儿出现2次及以上喘息比例低于对照组（χ2=5.14，P=0.02）。Ⅰ+Ⅱ期研究期间治疗组医疗资源应用人数、β-受体激动剂应用人数、糖皮质激素应用人数、住院人数低于对照组（P<0.05）。在事后亚组分析中，治疗组有湿疹史与父母哮喘史的患儿中无症状天数〔（49.7±20.2）、（51.3±20.9）d〕多于对照组〔（36.3±20.4）、（37.8±19.3）d〕（t=2.19，P=0.03；t=2.24，P=0.03）。整个研究过程中没有患儿因不良反应退出研究，两组间胃肠道紊乱、皮疹、转氨酶升高发生率比较，差异均无统计学意义（χ2=0.23，P=0.63；χ2=0.03，P=0.86；χ2=0.15，P=0.69）。结论　口服孟鲁司特（4 mg）12周不能改善RSV毛细支气管炎患儿呼吸道症状，但能降低患儿反复喘息发作次数。口服孟鲁司特（4 mg）有一定效果且安全。
