Examining Acute Coronary Syndrome Across Ethnicity,Sex, and Age

Acute coronary syndrome (ACS) remains one of the leading causes of death in the United States. With its heightened prevalence, considerable variabilities in the disease process exist across ethnicities, sex, and age. This creates substantial disparities in the recognition and management of ACS, which consequently contributes to poor outcomes. It is of utmost importance that nurse practitioners remain vigilant, cognizant, and maintain a high index of suspicion to accurately identify ACS presentations and thus efficaciously intervene to successfully manage the disease process.     

中医药治疗特发性肺纤维化的系统评价再评价＊

目的 对中医药治疗特发性肺纤维化（idiopathic pulmonary fibrosis， IPF）的系统评价（SRs）进行再评价。方法 检索知网、中国生物医学数据库、维普、万方、The Cochrane Library、Web of Science、PubMed和EMbase数据库，纳入中医药治疗IPF的SRs，截止2021年5月。使用AMSTAR 2量表进行方法学质量评价，GRADE系统工具进行结局指标证据质量分级。结果 共纳入28篇文献，试验组除辨证论治外，治疗方法集中在活血化瘀、补肺益气等方面，基本符合治疗法则。结果显示中医药治疗IPF可以提高有效率、增加肺功能、提高PaO₂、增加6WMD、缓解临床症状、提高患者的生活质量等。AMSTAR 2量表评价，所纳入SRs均有多项关键条目不达标，整体方法学质量等级不高。采用GRADE工具进行质量分级，一共234个结局指标，无高等证据质量，整体证据等级不高。结论 中医药对比西医治疗IPF有效且不良反应不明显，但RCT研究和系统评价研究方法质量尚有缺陷，完全按照西医评价指标可能会低估真实结果，未来需要更规范的研究及适合中医的评价指标，对中医药研究的安全性方面关注还有待提高。

短时程脊髓电刺激治疗爆发痛合并触诱发痛的急性期带状疱疹的临床研究

目的探讨短时程脊髓电刺激(temporary spinal cord stimulation, tSCS)治疗爆发痛合并触诱发痛的急性期带状疱疹的临床疗效。方法回顾性地分析同济大学附属第十人民医院疼痛科2020年1月—2020年12月收治的52例接受tSCS治疗的爆发痛合并触诱发痛的急性期带状疱疹患者的临床资料，评估在治疗前、治疗后3d、7d、14d、3个月、6个月的总体疼痛情况(numerical rating scale, NRS)评分、(simple McGill scores, McGill)评分、爆发痛情况(发生率、NRS评分、次数以及持续时间)、触诱发痛情况(发生率、分级)、术后不良反应等；评估在治疗前、治疗后7d、3个月、6个月的睡眠时长、睡眠中醒来次数、疼痛障碍指数(pain disorder index, PDI)、功能状态评分(Karnofsky score, KPS)、抑郁症筛查量表(patient health questionnaire depression module scale, PHQ-9)和焦虑症筛查量表(generalized anxiety disorder-7 scale, GAD-7)等。结果与治疗前相比，治疗后3d、7d、14d、3个月、6个月的总体疼痛NRS评分、总体疼痛MCGILL评分、静息痛NRS评分明显降低(均P<0.001)；与治疗前相比，治疗后3d、7d、14d、3个月、6个月的的爆发痛NRS评分明显降低(均P<0.05)，治疗后14d、3个月、6个月时的爆发痛次数以及持续时间都明显降低(均P<0.05)；与治疗前比较，患者治疗后7d、14d、3个月、6个月时的触诱发痛的分级都明显降低，差异均有统计学意义(均P<0.05)；与治疗前相比，治疗后14d、3个月、6个月的PDI评分明显降低(P<0.05)；与治疗前相比，治疗后14d、3个月、6个月的PHQ-9评分和GAD-7评分都明显减少(P<0.05)，与术前的药物使用情况相比，治疗后各镇痛药使用人数普遍呈下降趋势；术中及整个随访期间未观察到严重不良事件。结论短时程脊髓电刺激对爆发痛合并触诱发痛的急性期带状疱疹具有较好的临床疗效。     

Understanding Hispanic Patient Satisfaction with Telehealth During COVID-19

BackgroundRecent studies have described the use of telehealth for pediatric surgical care during the COVID-19 pandemic. We aimed to evaluate equity in telehealth use by comparing rates of utilization and satisfaction with pediatric surgical telemedicine among Hispanic patients.MethodsWe conducted a retrospective cohort study of patients seen by a surgical subspecialty provider in the outpatient setting at a quaternary pediatric hospital between April 1 and June 30, 2020. Patients evaluated in the same three-month period in 2019 were analyzed as a historic control. Differences in Family Experience Survey (FES) responses based on race and ethnicity and preferred language of care were assessed using univariable and multivariable generalized linear modeling.ResultsThe pandemic cohort included fewer patients of Hispanic ethnicity and fewer Spanish-speakers. After controlling for visit type, comparison of Spanish-speaking and English-speaking patients revealed that Spanish-speaking families had significantly lower scores for FES items that evaluated healthcare provider explaining (IRR 0.74, 95% CI: 0.61–0.90), listening (IRR 0.76, 95% CI: 0.63–0.92), and time spent with the family (IRR 0.73, 95% CI: 0.60–0.89). There were no differences in FES responses based on insurance status or degree of medical complexity.ConclusionsTelehealth services were less commonly used among Hispanic and Spanish-speaking patients. Language may differentially affect family satisfaction with healthcare and telehealth solutions. Strategies to mitigate these inequities are needed and may include strengthening interpreter services and providing language-concordant care.Level of evidenceLevel IV.     

Control of immunity and allergy by steroid hormones

Steroid hormones, especially glucocorticoids, androgens, and estrogens, have profound influence on immunity. Recent studies using cell-type specific steroid hormone receptor-deficient mice have revealed the precise roles of some of these hormones in the immune system. Glucocorticoids are known to have strong anti-inflammatory and immunosuppressive effects and pleiotropic effects on innate and adaptive immune responses. They suppress the production of inflammatory cytokines by macrophages and DCs and the production of IFN-γ by NK cells, thus inhibiting innate immunity. By contrast, glucocorticoids enhance the immune response by inducing the expression of IL-7R and CXCR4 in T cells and the accumulation of T cells in lymphoid organs in accordance with the diurnal change of the glucocorticoid concentration. Thus, glucocorticoids suppress innate immunity but enhance adaptive immunity. Androgens suppress the homeostasis and activation of ILC2s and the differentiation of Th2 and Th17 cells and enhance the suppressive function of Tregs, thereby alleviating allergic airway inflammation. Thus, these steroid hormones have pleiotropic functions in the immune system. Further investigations are awaited on the regulation of immunity and allergy by estrogens using cell-specific steroid hormone receptor-deficient mice.
