A systematic review of axillary nodal irradiation for the management of the axilla in patients with early-stage breast cancer

BackgroundGiven numerous publications and clinical trials regarding axillary management in breast cancer, we sought to summarize this complex literature to help clarify this field for clinicians. This systematic review focuses on the role of irradiation of the axillary nodes (locoregional nodal irradiation [LRNI]) in the management of the axilla in patients with early-stage breast cancer in various clinical settings.MethodsWe searched MEDLINE and EMBASE databases, the Cochrane library, the proceedings of the ASCO, the ASTRO, the ESMO, the ESTRO, and the San Antonio Breast Cancer Symposium (2016–2019) meetings. The quality of the studies was assessed with design-specific tools. The study was registered in PROSPERO.ResultsWe included one systematic review, one individual patient data (IPD) meta-analysis, and five randomized controlled trials (RCTs). After axillary lymph node dissection (ALND), LRNI resulted in small benefits in breast cancer specific mortality, locoregional recurrence, and distant metastases-free survival but not overall survival. After a positive sentinel node biopsy (SLNB), LRNI may provide equivalent locoregional control and disease-free survival (DFS) compared to ALND with a lower risk of lymphedema. No randomized data is available for the neoadjuvant setting.ConclusionsThe summary of the role of radiation, is relevant to radiation oncologists for choosing the correct cohort of patient requiring LRNI and to surgeons making clinical decisions regarding the timing and type of breast reconstruction offered to patients.     

Primary and recurrent regional metastases for lateralized oral cavity squamous cell carcinoma

ObjectivesMap regional lymph node metastases for lateralized oral cavity squamous cell carcinoma (OCSCC) and evaluate factors associated with regional metastases and recurrence.Materials and methodsRetrospective cohort study of 715 patients with lateralized OCSCC surgically treated in 1997–2011. Analysis was performed using log-rank, Kaplan-Meier, and multivariable logistic and Cox regression.ResultsRegional metastases were identified in ipsilateral levels IIA (24%), IB (18%), III (13%), V (9%), IV (7%), IA (2%) and IIB (1%) and the contralateral neck (3%). Lymphovascular invasion (LVI) (Hazard Ratio [HR] 2.2, 95% Confidence Interval [CI] 1.2–3.9) and T category (T3 vs. T1: HR 4.1, 95% CI 1.9–9.3; T4 vs. T1: HR 2.3, 95% CI 1.2–4.3) were associated with regional metastases. Most (71%) isolated regional metastatic recurrences were in undissected levels of the neck, including 58% in levels IV and V. Tumors of the hard palate (HR 4.3, 95% CI 1.2–16.1), upper alveolus (HR 3.2, 95% CI 1.0–4.7) or with LVI (HR 2.0, 95% CI 1.0–3.9) were associated with isolated regional recurrence. For upper alveolar/hard palate tumors, depth of invasion (DOI) ≥4 mm (P = .003) and LVI (P = .04) were associated with regional metastases.ConclusionsFor lateralized OCSCC, elective neck dissection of level IIB or the contralateral neck may rarely be needed, but additional surgical or radiation treatment of levels IV and V may be considered based on patient risk factors, including T category 3–4 or LVI. For upper alveolar/hard palate tumors, DOI ≥4 mm is an appropriate threshold for elective neck dissection.     

《医疗质量管理办法》中医疗质量概念及相关问题探讨

采用文献复习和实证研究经验的方法对《医疗质量管理办法》中涉及的医疗质量概念及相关问题进行探讨。《医疗质量管理办法》中的医疗质量的定义存在重大缺失,没有涉及医疗服务的结果,特别是患者安全。医疗质量的定义应与国际相关权威机构保持一致,应高度重视医疗服务的结果,特别是患者安全。     

慢阻肺急性加重期患者延迟就医与家庭动力学的相关性研究

目的研究慢阻肺急性加重期患者延迟就医与家庭动力学的相关性,希望能够为慢阻肺急性加重期患者拟定护理措施提供科学依据。方法选取2017年1月-2019年12月我院240例诊断为慢阻肺急性加重期的患者为研究对象。根据患者入院就医的时间进行分组,时间≥24h的延迟就医的患者为观察组,时间<24h的及时就医患者为对照组。结果两组患者在文化水平、家庭年收入、在职状态、医疗保险和婚姻状况和APACHEⅡ评分比较(P<0.05)。观察组患者疾病观念、个性化、系统逻辑和家庭氛围得分比对照组高(P<0.05)。Pearman的相关性分析结果显示:慢阻肺急性加重期患者延迟就医时间与各个层面分数以及家庭动力总分呈现负相关性(P<0.05)。应变量为延迟就医为应变量,患者的一般资料为自变量,经Logistic回归分析结果表明:延迟就医的影响因素为文化水平、家庭动力评分、职业状态、家庭收入、婚姻状况和APACHEⅡ评分。结论慢阻肺急性加重期患者家庭动力总分与疾病观念、个性化、系统逻辑和家庭氛围得分与延迟就医时间呈现负相关性,患者延迟就医的影响因素是家庭动力学评分。

A Pilot First-in-Human Study of Embrace,a Polyethylene Glycol-Based Liquid Embolic Agent,in the Embolization of Malignant and Benign Hypervascular Tumors

PurposeTo investigate the safety and efficacy of an aqueous polyethylene glycol-based liquid embolic agent, Embrace Hydrogel Embolic System (HES), in the treatment of benign and malignant hypervascular tumors.Materials and MethodsA prospective, single-arm, multicenter study included 8 patients, 5 males and 3 females, with a median age of 58.5 years (30–85 years), who underwent embolization in 8 tumors between October 2019 and May 2020. Technical success was defined as successful delivery of HES to the index vessel, with disappearance of >90% of the targeted vascular enhancement or, for portal vein embolization, occlusion of the portal branches to the liver segments for future resection. The volume of HES administered, ease of use (5 point Likert scale), administration time, and adverse events (AEs) were recorded. Evaluation was performed at 7, 30, and 90 days via clinical assessment and blood testing, and follow-up imaging was performed at 30 days.ResultsEight patients were enrolled, and 10 embolizations were performed in 8 lesions. Tumors included hepatocellular carcinoma (n = 4), renal angiomyolipoma (n = 3), and intrahepatic cholangiocarcinoma (n = 1). Technical success was 100%, and the average ease of use was 3.3 ± 1.0 SD. The HES delivery time was 1–28 minutes (median, 16.5 minutes), and the HES volume injected was 0.4–4.0 mL (median, 1.3 mL). All patients reached 30-day follow-up with imaging, and 6 patients reached 90-day follow-up. There were 3 serious AEs in 2 patients that were unrelated to the embolic agent.ConclusionHES resulted in a 100% embolization technical success rate. The product ease of use was acceptable, and no target vessel recanalization was noted on follow-up imaging at 30 days.     

基层医疗卫生机构居家护理服务的安全支持和医务人员服务意愿调查研究

背景 人口老龄化趋势下，罹患多种慢性病的失能或半失能老年人对居家医疗护理服务需求迫切，但基层医务人员提供居家医疗护理服务存在较大的医疗风险和安全隐患，加强居家医疗护理服务的安全管理，有利于提高基层医务人员提供居家医疗护理服务的意愿。 目的 调查基层医疗卫生机构对居家护理服务的安全支持情况和医务人员的服务意愿，为进一步推动居家医疗护理服务发展提供参考依据。 方法 2021年8—10月，采用便利抽样法在四川省五大经济区抽取49所基层医疗卫生机构的1 131例医务人员。自行设计调查问卷，以"问卷星"电子问卷的形式收集资料。问卷内容包括医务人员的一般情况（8个条目）、提供居家医疗护理服务的经历（2个条目）、医疗机构对医务人员的安全支持（7个条目）、医务人员的居家医疗护理服务意愿（1个条目）。比较不同特征医务人员提供居家医疗护理服务的意愿，采用二元Logistic回归分析医务人员提供居家医疗护理服务意愿的影响因素。 结果 1 131例基层医务人员中，692例（61.18%）报告有过居家医疗护理服务的经历，193例（17.06%）报告在服务过程中发生过不良事件/安全事件，531例（46.95%）报告其所在医疗机构未评估过患者接受居家医疗护理服务的安全风险，199例（17.60%）表示所在机构评估了医务人员提供居家医疗护理服务的安全风险，299例（26.44%）在居家医疗护理服务过程中使用APP定位系统，273例（24.14%）由机构配备报警、延迟预警等设备，807例（71.35%）表示居家医疗护理服务过程中没有获得所在机构内其他医务人员的支持措施，303例（26.79%）表示机构曾组织居家医疗护理服务的专项研讨活动，352例（31.12%）表示接受过有关居家医疗护理服务专项培训，853例（75.42%）表示愿意提供居家医疗护理服务。二元Logistic回归分析结果显示，就职的基层医疗卫生机构类型，目前受聘的专业技术职称，医疗机构是否评估过患者接受居家医疗护理服务的安全风险，在居家医疗护理服务过程中是否配备报警、延迟预警等设备，是否参加过有关居家医疗护理服务的专项培训，对医务人员提供居家医疗护理服务意愿有影响（P<0.05）。 结论 现阶段居家医疗护理服务的安全支持不足，多种因素影响基层医务人员提供居家医疗护理服务的意愿。基层医疗卫生机构应加强对患者接受居家医疗护理服务安全风险的评估，为提供居家医疗护理服务的医务人员配备报警、延迟预警等设备，积极举办居家医疗护理服务相关的专项培训并鼓励医务人员参加，以降低医务人员提供居家医疗护理服务的风险，保障其人身安全。
