基于奥马哈理论的围手术期全程康复管理对TAVR患者心理应激、6 min步行距离及并发症的影响

目的 探讨基于奥马哈理论的围手术期全程康复管理对经导管主动脉瓣置换术（transcatheter aortic valve replacement，TAVR）患者心理应激、6 min步行距离及并发症的影响。 方法 选取我院74例TAVR患者，采用随机数字表法分为2组，各37例。对照组采取传统围术期护理，在对照组基础上，观察组采取基于奥马哈理论的围手术期全程康复管理。统计2组并发症、护理满意度及护理前后心理应激、心功能指标、健康行为（health promotionlifestyleprofile-Ⅱ，HPLP-Ⅱ）、6 min步行距离及生活质量。 结果 观察组干预后左心室舒张末期内径、跨瓣压差较对照组低，主动脉瓣面积、左心室射血分数高于对照组（P＜0.05）；观察组干预后特质焦虑（Trait Anxiety Inventory，T~AI）、状态焦虑（State Anxiety Inventory，S~AI）评分低于对照组（P＜0.05）；观察组干预后HPLP-Ⅱ量表6个维度评分高于对照组（P＜0.05）；观察组术后3个月、6个月生活质量及6 min步行距离高于对照组（P＜0.05）；2组并发症比较差异无统计学意义（P＞0.05）。 结论 基于奥马哈理论的围手术期全程康复管理应用于TAVR患者，可减轻其心理应激，提高患者健康促进生活方式水平，预防并发症发生，在改善患者心功能、运动耐力和提高患者护理满意度方面具有积极意义。

Method’s corner: Allergist’s guide to network meta-analysis

Network meta-analyses (NMAs) simultaneously estimate the effects of multiple possible treatment options for a given clinical presentation. For allergists to benefit optimally from NMAs, they must understand the process and be able to interpret the results. Through a worked example published in Pediatric Allergy and Immunology, we summarize how to identify credible NMAs and interpret them with a focus on recent innovations in the GRADE approach (Grading of Recommendations Assessment, Development, and Evaluation). NMAs build on traditional systematic reviews and meta-analyses that consider only direct paired comparisons by including indirect evidence, thus allowing the simultaneous assessment of the relative effect of all pairs of competing alternatives. Our framework informs clinicians of how to identify credible NMAs and address the certainty of the evidence. Trustworthy NMAs fill a critical gap in providing key inferences using direct and indirect evidence to inform clinical decision making when faced with more than two competing courses of treatment options. This document will help allergists to identify trustworthy NMAs to enhance patient care.     

Goal-directed fluid removal with furosemide versus placebo in intensive care patients with fluid overload: A randomised,blinded trial (GODIF trial—First version)

Background

Salt and water accumulation leading to fluid overload is associated with increased mortality in intensive care unit (ICU) patients, but diuretics' effects on patient outcomes are uncertain. In this first version of the GODIF trial, we aimed to assess the effects of goal-directed fluid removal with furosemide versus placebo in adult ICU patients with fluid overload.

Methods

We conducted a multicentre, randomised, stratified, parallel-group, blinded, placebo-controlled trial in clinically stable, adult ICU patients with at least 5% fluid overload. Participants were randomised to furosemide versus placebo infusion aiming at achieving neutral cumulative fluid balance as soon as possible. The primary outcome was the number of days alive and out of the hospital at 90 days.

Results

The trial was terminated after the enrolment of 41 of 1000 participants because clinicians had difficulties using cumulative fluid balance as the only estimate of fluid status (32% of participants had their initially registered cumulative fluid balance adjusted and 29% experienced one or more protocol violations). The baseline cumulative fluid balance was 6956 ml in the furosemide group and 6036 ml in the placebo group; on day three, the cumulative fluid balances were 1927 ml and 5139 ml. The median number of days alive and out of hospital at day 90 was 50 days in the furosemide group versus 45 days in the placebo group (mean difference 1 day, 95% CI -19 to 21, p-value .94).

Conclusions

The use of cumulative fluid balance as the only estimate of fluid status appeared too difficult to use in clinical practice. We were unable to provide precise estimates for any outcomes as only 4.1% of the planned sample size was randomised.

目的 探讨抗结核药物雾化吸入疗法联合纤支镜介入疗法治疗支气管内膜结核的可行性。方法 选取2018年3月～2019年3月在沈阳市第十人民医院住院治疗的80例支气管内膜结核患者作为研究对象,将患者随机分为两组,各40例。对照组予2HRZE/10HR方案口服药物抗结核治疗,研究组在对照组基础上,应用抗结核药物雾化吸入疗法联合纤支镜介入疗法。比较两组患者治疗效果、治疗的总疗程、不良反应及并发症的发生率。结果 研究组在总有效率、痰菌转阴时间及总治疗疗程方面分别为92.5%、(28.77±4.12)d、(39.2±6.28)周,相对于对照组的为75.0%、(39.49±5.72)d、(47.3±6.65)周,两组差异均有统计学意义(P0.05)。除术中出血方面两组有统计学差异(P0.05)外,两组其余不良反应者无明显差异(P0.05)。结论 对EBTB患者,在常规抗结核治疗基础上联合使用药物雾化吸入疗法和纤维支气管镜介入疗法治疗可迅速缓解患者临床症状,缩短菌阳患者的痰菌转阴时间及治疗疗程,促进肺不张恢复,提高治疗效果。     

芒针对脊髓损伤大鼠运动功能和炎症水平的影响

目的探究芒针深刺秩边穴对大鼠脊髓损伤后运动功能的影响及可能作用机制。方法选择健康雄性Wister大鼠81只,随机分为正常组、模型组和芒针组(正常组9只,其余两组各36只),采用改良Allen's造模法制备大鼠脊髓中度损伤模型,模型组不做特殊处理,芒针组采用芒针深刺秩边穴,每日1次,每次30 min。分别于术后1 d、3 d、5 d、7 d行BBB(Basso-Beattie-Bresnahan)运动功能评分;术后1 d、3 d、5 d、7 d取受损段脊髓组织行酶联免疫吸附测定(ELISA)、实时荧光定量PCR(RT-qPCR)和苏木素-伊红染色(HE染色)。结果术后5 d和7 d,芒针组大鼠BBB评分高于模型组,差异有统计学意义(P<0.01);脊髓损伤后,模型组和芒针组大鼠脊髓组织中高迁移率族蛋白B1(HMGB1)、核转录因子kB(NF-kB)、白介素-6(IL-6)含量及HMGB1mRNA、NF-kBmRNA、IL-6mRNA水平显著升高(P<0.05);受损的脊髓组织松散,灰质中有许多空洞形成,伴有炎性细胞浸润。芒针治疗后,芒针组大鼠脊髓组织中HMGB1、NF-kB、IL-6含量及HMGB1mRNA、NF-kBmRNA、IL-6mRNA水平较模型组降低,且在3 d、5 d、7 d差异有统计学意义(P<0.05);受损部位的空洞及炎性细胞逐渐减少。结论脊髓损伤后,炎症因子的大量聚集引起级联性炎症反应,影响大鼠运动功能的恢复。芒针的抗炎机制可能包括抑制HMGB1的表达,降低NF-kB信号通路的传导,下调促炎因子IL-6的分泌。
