聪耳通窍汤联合耳针对老年神经性耳鸣近远期疗效观察

目的探讨聪耳通窍汤联合耳针治疗老年神经性耳鸣患者的近远期疗效。方法选取耳鼻喉科门诊收治的老年神经性耳鸣患者136例,按随机数字表法分组,对照组68例予以耳针治疗,研究组68例在对照组基础上予以聪耳通窍汤治疗。检测比较两组间近、远期临床疗效、甲襞微循环指标、血液流变学指标以及不良反应发生率。结果治疗后,对照组总有效率为67.64%(46/68)低于研究组总有效率83.82%(57/68),具有统计学意义(P<0.05);随访6个月后,对照组总有效率64.71%(44/68)低于研究组总有效率89.71%(61/68),具有统计学意义(P<0.05);与对照组比较,研究组治疗后甲襞微循环襻周积分、管襻积分、流态积分及总积分较低,治疗后血浆黏度、高切全血黏度、低切全血黏度及红细胞压积较低,差异具有统计学意义(P<0.05);治疗中出现的不良反应为恶心、腹胀、针刺部位疼痛,两组间不良反应发生率无统计学差异(P>0.05)。结论聪耳通窍汤联合耳针治疗老年神经性耳鸣患者的近远期疗效均较好,能明显改善患者微循环状态及血液流变学指标,减轻内耳循环障碍,具有较高安全性。     

A process evaluation of implementing a vocational enablement protocol for employees with hearing difficulties in clinical practice

Objective: A multidisciplinary vocational rehabilitation programme, the Vocational Enablement Protocol (VEP) was developed to address the specific needs of employees with hearing difficulties. In the current study we evaluated the process of implementing the VEP in audiologic care among employees with hearing impairment. Design: In conjunction with a randomized controlled trial, we collected and analysed data on seven process parameters: recruitment, reach, fidelity, dose delivered, dose received and implemented, satisfaction, and perceived benefit. Study sample: Sixty-six employees with hearing impairment participated in the VEP. The multidisciplinary team providing the VEP comprised six professionals. Results: The professionals performed the VEP according to the protocol. Of the recommendations delivered by the professionals, 31% were perceived as implemented by the employees. Compliance rate was highest for hearing-aid uptake (51%). Both employees and professionals were highly satisfied with the VEP. Participants rated good perceived benefit from it. Conclusions: Our results indicate that the VEP could be a useful treatment for employees with hearing difficulties from a process evaluation perspective. Implementation research in the audiological setting should be encouraged in order to further provide insight into parameters facilitating or hindering successful implementation of an intervention and to improve its quality and efficacy.     

Immunogenicity and safety of a fully liquid aluminum phosphate adjuvanted Haemophilus influenzae type b PRP-CRM197-conjugate vaccine in healthy Japanese children: A phase III,randomized, observer-blind,multicenter, parallel-group study

BackgroundBroad use of monovalent Haemophilus influenzae type b (Hib) conjugate vaccines based on the capsular polysaccharide polyribosyl-ribitol phosphate (PRP), has significantly reduced invasive Hib disease burden in children worldwide, particularly in children aged <1 year. In Japan, PRP conjugated to tetanus toxoid (PRP-T) vaccine has been widely used since the initiation of public funding programs followed by a routine vaccination designation in 2013.MethodsWe compared the immunogenicity and safety of PRP conjugated to a non-toxic diphtheria toxin mutant (PRP-CRM₁₉₇) vaccine with the PRP-T vaccine when administered subcutaneously to healthy Japanese children in a phase III study. Additionally, we evaluated the immunogenicity and safety profiles of a diphtheria–tetanus acellular pertussis (DTaP) combination vaccine when concomitantly administered with either PRP-CRM₁₉₇ or PRP-T vaccines. The primary endpoint was the “long-term seroprotection rate”, defined as the group proportion with anti-PRP antibody titers ⩾1.0 μg/mL, after the primary series.ResultsLong-term seroprotection rates were 99.3% in the PRP-CRM₁₉₇ group and 95.6% in the PRP-T group. The intergroup difference (PRP-CRM₁₉₇ group – PRP-T group) was 3.7% (95% confidence interval: 0.099–7.336), demonstrating that PRP-CRM₁₉₇ vaccine was non-inferior to PRP-T vaccine (p < 0.0001). Furthermore, the “short-term seroprotection rate” (anti-PRP antibody titer ⩾0.15 μg/mL) before booster vaccination was higher in the PRP-CRM₁₉₇ group than in PRP-T. Concomitant administration of PRP-CRM₁₉₇ vaccine with DTaP vaccine showed no differences in terms of immunogenicity compared with concomitant vaccination with PRP-T vaccine and DTaP vaccine. Although CRM₁₉₇ vaccine had higher local reactogenicity, overall, both Hib vaccines had acceptable safety and tolerability profiles.ConclusionThe immunogenicity of PRP-CRM₁₉₇ vaccine administered subcutaneously as a three-dose primary series in children followed by a booster vaccination 1 year after the primary series induced protective levels of Hib antibodies with no safety or tolerability concerns.Clinical trial registry: Registered on ClinicalTrials.gov: NCT01379846     

Caution! Overestimation of treatment effects of corticosteroid therapy for community-acquired pneumonia in a meta-analysis of randomized controlled trials

It is well known that a meta-analysis of randomized controlled trials aims to increase the power and precision of the estimated intervention effects. However, when a meta-analysis includes a limited number of patients and a small number of events, overestimation of intervention effect estimates may occur and could cause spurious results. Although many biases can cause the overestimation, random error may be the most common cause. Trial sequential analysis (TSA) can explore the independent effect of random error on intervention effect estimates in meta-analyses and protect meta-analyses against overestimation due to random error.
