Association of Multimodal Pain Control with Patient-Reported Outcomes in Children Undergoing Surgery

IntroductionOur aim was to describe practices in multimodal pain management at US children's hospitals and evaluate the association between non-opioid pain management strategies and pediatric patient-reported outcomes (PROs).MethodsData were collected as part of the 18-hospital ENhanced Recovery In CHildren Undergoing Surgery (ENRICH-US) clinical trial. Non-opioid pain management strategies included use of preoperative and postoperative non-opioid analgesics, regional anesthetic blocks, and a biobehavioral intervention. PROs included perioperative nervousness, pain-related functional disability, health-related quality of life (HRQoL). Associations were analyzed using multinomial logistic regression models.ResultsAmong 186 patients, 62 (33%) received preoperative analgesics, 186 (100%) postoperative analgesics, 81 (44%) regional anesthetic block, and 135 (73%) used a biobehavioral intervention. Patients were less likely to report worsened as compared to stable nervousness following regional anesthetic block (relative risk ratio [RRR]:0.31, 95% confidence interval [CI]:0.11–0.85), use of a biobehavioral technique (RRR:0.26, 95% CI:0.10–0.70), and both in combination (RRR:0.08, 95% CI:0.02–0.34). There were no associations of non-opioid pain control modalities with pain-related functional disability or HRQoL.ConclusionUse of postoperative non-opioid analgesics have been largely adopted, while preoperative non-opioid analgesics and regional anesthetic blocks are used less frequently. Regional anesthetic blocks and biobehavioral interventions may mitigate postoperative nervousness in children.Level of evidenceIII.

目的了解不同机种军事飞行员运动心肺功能有无差异。方法飞行员分为高性能战斗机和普通战斗机两组,采用意大利COSMED运动心肺功能测试仪,选择自行车功率计运动方式,以25 W/min功率递增速率极量运动方案,进行运动心肺功能测试,比较两组运动心肺功能数据的主要指标。结果两组飞行员各207例完成运动心肺功能测试,两组的年龄、身高、体质量和体质量指数差异均无统计学意义(P均>0.05)。两组数据的主要指标中,除了峰值氧脉搏[高性能战斗机组(15.36±2.43)mL/bpm,普通战斗机组(14.95±2.13)mL/bpm]差异有统计学意义(P=0.038),其他差异均无统计学意义,而且各指标差异幅度均较小,高性能战斗机飞行员组的峰值氧脉搏高于普通战斗机组2.74%。结论综合比较,高性能战斗机和普通战斗机飞行员的运动心肺功能无明显差异,提示两组飞行员日常有氧运动训练效果一致,在转换飞行机种时,可以不受运动心肺功能的限制。     

The EQ-HWB: Overview of the Development of a Measure of Health and Wellbeing and Key Results

ObjectivesExisting measures for estimating quality-adjusted life-years are mostly limited to health-related quality of life. This article presents an overview of the development the EQ-HWB (EQ Health and Wellbeing), which is a measure that encompasses health and wellbeing.MethodsStages: (1) Establishing domains through reviews of the qualitative literature informed by a conceptual framework. (2) Generation and selection of items to cover the domains. (3) Face validation of these items through qualitative interviews with 168 patients, social care users, general population, and carers across 6 countries (Argentina, Australia, China, Germany, United Kingdom, United States). (4) Extensive psychometric testing of candidate items (using classical, factor analysis, and item response theory methods) on > 4000 respondents in the 6 countries. Stakeholders were consulted throughout.ResultsA total of 32 subdomains grouped into 7 high-level domains were identified from the qualitative literature and 97 items generated to cover them. Face validation eliminated 36 items, modified 14, and added 3. Psychometric testing of 64 items found little difference in missing data or problems with response distribution, the conceptual model was confirmed except in China, and most items performed well in the item response theory in all countries. Evidence was presented to stakeholders in 2 rounds of consultation to inform the final selection of items for the EQ-HWB (25-item) and the short version of EQ-HWB (9-items).ConclusionsEQ-HWB measures have been developed internationally for evaluating interventions in health, public health, and social care including the impact on patients, social care users, and carers.     

二维斑点追踪显像技术评估窒息新生儿左心室纵向收缩功能与心肌损害的相关性

【摘要】目的 探讨二维斑点追踪显像技术(2D-STI)评估新生儿窒息合并心肌损害后左心室整体及局部心肌的纵向收缩功能在早期诊断窒息新生儿心肌损害中的临床价值。方法 选择2019年07月至2020年12月期间在右江民族医学院附属医院新生儿科住院的足月窒息新生儿61例，经临床确诊合并心肌损害，根据Apgar评分分为轻度组31例和重度组30例，选择同期住院出生的正常足月新生儿30例作为对照组。检测受检者的血清肌酸激酶同工酶（CK-MB）、肌钙蛋白（cTnT）、左室舒张期前后径（LVDId）、左室射血分数（LVEF）、左室短轴缩短率（LVFS）、辛普森法左室射血分数（Simpson EF）、左室三腔心整体应变（GLS-LAX）、左室四腔心整体应变（GLS-A4C）、左室两腔心整体应变（GLS-A2C）、左室整体应变（GLS-AVG）,分析GLS-AVG和CK-MB、cTnT三者的相关性。结果 三组间CK-MB和cTnT比较差异有统计学意义（P<0.05）。三组间性别、体重、胎龄均无统计学差异（P>0.05）。三组间LVDId、LVEF、LVFS、Simpson EF比较差异无统计学意义（P>0.05）。GLS-AVG与CK-MB呈负性相关（r=-0.515，P=0.000），GLS-AVG与cTnT呈负性相关（r=-0.912，P=0.000）。结论 GLS-AVG与CK-MB、cTnT具有相关性，GLS-AVG可作为窒息新生儿心肌损害早期诊断指标。     

注意缺陷多动障碍儿童执行功能的评估与干预

ADHD儿童认知障碍的主要特征之一是执行功能损害,涉及包括前额叶皮层在内的特定脑区域及多层级脑网络异常。执行功能按照功能性分为冷-热两方面:冷执行功能损害主要表现于反应抑制、工作记忆以及认知灵活性等;热执行功能损害通常涉及延迟满足、赏罚相关决策、自我调节及情绪调节等。ADHD儿童的执行功能评估应基于可信范式进行文化适应性调整。临床干预不能单一聚焦于冷执行功能,需关注儿童的身体发育以及热执行功能(情绪社会方面)的发展进程,结合其他共病与心理状况,进行全面的动态随访与干预,以达到最佳的长期疗效。     

The role of dark adaptation in understanding early AMD

The main aim of the paper is to discuss current knowledge on how Age Related Macular Degeneration (AMD) affects Dark Adaptation (DA). The paper is divided into three parts. Firstly, we outline some of the molecular mechanisms that control DA. Secondly, we review the psychophysical issues and the corresponding analytical techniques. Finally, we characterise the link between slowed DA and the morphological abnormalities in early AMD.Historically, DA has been regarded as too cumbersome for widespread clinical application. Yet the technique is extremely useful; it is widely accepted that the psychophysically obtained slope of the second rod-mediated phase of the dark adaptation function is an accurate assay of photoreceptor pigment regeneration kinetics. Technological developments have prompted new ways of generating the DA curve, but analytical problems remain. A simple potential solution to these, based on the application of a novel fast mathematical algorithm, is presented. This allows the calculation of the parameters of the DA curve in real time.Improving current management of AMD will depend on identifying a satisfactory endpoint for evaluating future therapeutic strategies. This must be implemented before the onset of severe disease. Morphological changes progress too slowly to act as a satisfactory endpoint for new therapies whereas functional changes, such as those seen in DA, may have more potential in this regard. It is important to recognise, however, that the functional changes are not confined to rods and that building a mathematical model of the DA curve enables the separation of rod and cone dysfunction and allows more versatility in terms of the range of disease severity that can be monitored. Examples are presented that show how analysing the DA curve into its constituent components can improve our understanding of the morphological changes in early AMD.     

早孕期监测子宫动脉多普勒参数在预测低危人群不良妊娠结局的价值

目的 建立妊娠11~13+6周子宫动脉多普勒参数在低危人群中的正常参考值，同时评估其对不良妊娠结局的预测价值。方法 收集2019年6月至2021年6月于我院行产前超声检查的妊娠11~13+6周孕妇，根据妊娠结局分组。收集两侧子宫动脉多普勒指标，包括搏动指数（PI）、阻力指数（RI）、舒张早期是否有切迹，以及孕妇基本临床资料和胎儿出生信息，将以上相关参数进行统计学分析。结果 最终纳入800例孕妇，包括正常妊娠结局组740例和不良妊娠结局组60例。两组孕妇体质量指数（BMI）、分娩孕周和胎儿出生体质量比较，差异均有统计学意义（均P＜0.05）。随着孕周的增加，子宫动脉两侧平均搏动指数（mPI）、平均阻力指数（mRI）和两侧舒张早期切迹检出率均呈逐渐下降的趋势。ROC曲线分析显示，mPI、mRI及两侧舒张早期切迹预测妊娠结局的曲线下面积（AUC）分别为0.542、0.574、0.521，三者联合预测妊娠结局的AUC为0.648；孕妇BMI、年龄mPI、mRI及两侧舒张早期切迹预测妊娠结局的AUC为0.751。结论 建立了低危人群在妊娠11~13+6周子宫动脉多普勒参数的正常参考值范围。在妊娠11~13+6周单纯应用子宫动脉多普勒参数预测妊娠结局的价值有限，将子宫动脉参数与临床相关指标结合可提高对不良妊娠结局的预测价值。
