骨科围手术期患者静脉血栓栓塞症物理预防的最佳证据总结

目的总结骨科围手术期患者静脉血栓栓塞症（VTE）物理预防的证据，提高护理人员VTE物理预防措施实施依从性。方法根据澳大利亚JBI循证卫生保健中心证据总结方法学，检索骨科围手术期患者VTE物理预防相关文献，根据纳入文献类型，由研究人员独立进行质量评价，并提取、汇总最佳证据。结果共纳入文献17篇，包含10篇指南、1篇证据总结、2篇专家共识、4篇系统评价。经过分析，总结出7类共30条骨科围手术期患者VTE物理预防最佳证据。结论最佳证据可为护士提供循证依据。但在应用时，还需评估具体临床情境，结合专业判断和患者意愿，针对性选择证据，以促进护理质量的持续改进。     

基于SF-36的学术期刊编辑生存质量初步调查及影响因素探析

【目的】 初步了解学术期刊编辑生存质量状况,并探析其可能的影响因素,为改善学术期刊编辑身心健康、促进期刊可持续发展提供参考。【方法】 基于SF-36健康调查量表,在问卷星网站创建《学术期刊编辑生存质量调查问卷》,并发送至多个期刊编辑QQ群和微信群,在线下载答卷后进行分析。【结果】 在SF-36量表的8个维度中,生理角色维度的得分最高,总体健康维度的得分最低,与常模一致;生理职能维度的得分高于常模,躯体疼痛和精神健康维度的得分低于常模。多因素分析结果表明,每周加班频次≥3次、男性、工作年限在0~<10年、无职务、未与家人同住,以及所在期刊未被《中文核心期刊要目总览(2017年版)》、中国科学引文数据库、《中国科技论文统计源期刊》中的任一种收录可能是编辑生存质量的关键影响因素。【结论】 学术期刊编辑生存质量状况总体与国内常模接近,男性、独居、编龄短、加班频次高、期刊未被任一国内核心数据库收录可能与学术期刊编辑生存质量相关。     

植物花青素对肿瘤抑制作用的研究进展

植物花青素是一类可溶于水的类黄酮,主要存在于各种蔬菜水果中。常见的植物花青素主要分为天竺葵色素(Pelargonidin)、芍药色素(Peonidin)、矢车菊色素(Cyanidin)、锦葵色素(Malvidin)、矮牵牛色素(Petunidin)、飞燕草色素(Delphinidin)六种;植物花青素分子中含有共轭双键体系,并含有碱性或酸性基团,因而具有抗氧化、抗炎、调节免疫、抗衰老和抑癌等生物学作用,尤其以抑癌作用最为突出。因此,本文将对植物花青素的抑癌作用及可能的机制进行综述。     

Orchestration of the circadian clock and its association with Alzheimer's disease: Role of endocannabinoid signaling

Circadian rhythms are 24-hour natural rhythms regulated by the suprachiasmatic nucleus, also known as the "master clock". The retino-hypothalamic tract entrains suprachiasmatic nucleus with photic information to synchronise endogenous circadian rhythms with the Earth’s light-dark cycle. However, despite the robustness of circadian rhythms, an unhealthy lifestyle and chronic photic disturbances cause circadian rhythm disruption in the suprachiasmatic nucleus’s TTFL loops via affecting glutamate and γ-aminobutyric acid-mediated neurotransmission in the suprachiasmatic nucleus. Recently, considerable evidence has been shown correlating CRd with the incidence of Alzheimer's disease. The present review aims to identify the existence and signalling of endocannabinoids in CRd induced Alzheimer's disease through retino-hypothalamic tract- suprachiasmatic nucleus-cortex. Immunohistochemistry has confirmed the expression of cannabinoid receptor 1 in the suprachiasmatic nucleus to modulate the circadian phases of the master clock. Literature also suggests that cannabinoids may alter activity of suprachiasmatic nucleus by influencing the activity of their major neurotransmitter γ-aminobutyric acid or by interacting indirectly with the suprachiasmatic nucleus’s two other major inputs i.e., the geniculo-hypothalamic tract-mediated release of neuropeptide Y and serotonergic inputs from the dorsal raphe nuclei. Besides, the expression of cannabinoid receptor 2 ameliorates cognitive deficits via reduction of tauopathy and microglial activation. In conclusion, endocannabinoids may be identified as a putative target for correcting CRd and decelerating Alzheimer’s disease.     

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.
