病房护士发生职业性肌肉骨骼疾患工作场所的MAPO指数评估及影响因素分析

目的评估病房手工搬运患者护士发生职业性肌肉骨骼疾患(WMSDs)工作场所的MAPO指数,并了解工作场所中WMSDs发生的影响因素。方法采用便利抽样法,于2019年3—5月选取某三甲医院26个病区的317名护士为研究对象。以一般资料调查表、MAPO评估方法、米尺为研究工具,采用现场调查和测量法,对病房手工搬运患者护士发生WMSDs工作场所的情况进行综合评估。依据MAPO指数将病区分为红灯、黄灯、绿灯3个风险等级,亮黄灯代表有必要执行中期和长期干预计划,亮红灯意味着必须执行短期干预计划。对病房手工搬运患者护士发生WMSDs的影响因素采用多因素Logistic回归分析。结果本研究共发放问卷317份,回收有效问卷265份,有效回收率为83.6%。265名病房护士中,76.2%(202/265)的护士发生WMSDs。有13个(50.0%,13/26)病区亮红灯,包含158名(59.6%,158/265)护士;6个(23.1%,6/26)病区亮黄灯,包含92名(34.7%,92/265)护士;7个(26.9%,7/26)病区亮绿灯,包含15名(5.7%,15/265)护士。多因素Logistic回归分析显示,MAPO指数和病房分值是病房护士发生WMSDs的影响因素(OR值分别为1.056、1.571;P<0.05)。结论病房护士工作场所发生WMSDs的风险较高,建议从病床类型、床间距、辅助设备、护理人力资源配置和职业防护培训方面入手来减少护士WMSDs的发生。     

Serial Assessment of Depression and Anxiety by Patients and Providers in Women Receiving Chemotherapy for Early Breast Cancer

Background

Depression and anxiety are common in patients with breast cancer and associated with worse quality of life and treatment outcomes. Yet, these symptoms are often underrecognized and undermanaged in oncology practice. The objective of this study was to describe depression and anxiety severity and associated patient factors during adjuvant or neoadjuvant chemotherapy in women with early breast cancer using repeated single-item reports.

Materials and Methods

Depression and anxiety were measured from consecutive patients and their clinicians during chemotherapy infusion visits. Associations between psychiatric symptoms and patient characteristics were assessed using Fisher's exact tests for categorical variables and t tests for continuous variables. The joint relationship of covariates significant in unadjusted analyses was evaluated using log-binomial regression. Cohen's kappa was used to assess agreement between patient- and clinician-reported symptoms.

Results

In a sample of 256 patients, 26% reported at least moderately severe depression, and 41% reported at least moderately severe anxiety during chemotherapy, representing a near doubling in the prevalence of these symptoms compared with before chemotherapy. Patient-provider agreement was fair (depression: κ = 0.31; anxiety: κ = 0.28). More severe psychiatric symptoms were associated with being unmarried, having worse function, endorsing social activity limitations, using psychotropic medications, and having a mental health provider. In multivariable analysis, social activity limitations were associated with more severe depression (relative risk [RR], 2.17; 95% confidence interval [CI], 1.36–3.45) and anxiety (RR, 1.48; 95% CI, 1.05–2.09).

Conclusion

Oncologists frequently underestimate patients’ depression and anxiety and should consider incorporating patient-reported outcomes to enhance monitoring of mental health symptoms.

Implications for Practice

In this sample of 256 patients with breast cancer, depression and anxiety, measured using single-item toxicity reports completed by patients and providers, were very common during adjuvant or neoadjuvant chemotherapy. Patient-reported depression and anxiety of at least moderate severity were associated with multiple objective indicators of psychiatric need. Unfortunately, providers underrecognized the severity of their patients’ mental health symptoms. The use of patient-reported, single-item toxicity reports can be incorporated into routine oncology practice and provide clinically meaningful information regarding patients’ psychological health.

     

Optimize the management of urological tube-related emergencies during the coronavirus disease 2019 (COVID-19) pandemic

BackgroundTo introduce and determine the value of optimized strategies for the management of urological tube-related emergencies with increased incidence, complexity and operational risk during the global spread of coronavirus disease 2019 (COVID-19).MethodsAll emergent urological patients at Tongji Hospital, Wuhan, during the period of January 23 (the beginning of lockdown in Wuhan) to March 23, 2020, and the corresponding period in 2019 were recruited to form this study’s COVID-19 group and control group, respectively. Tongji Hospital has the most concentrated and strongest Chinese medical teams to treat the largest number of severe COVID-19 patients. Patients in the control group were routinely treated, while patients in the COVID-19 group were managed following the optimized principles and strategies. The case incidence for each type of tube-related emergency was recorded. Baseline characteristics and management outcomes (surgery time, secondary complex operation rate, readmission rate, COVID-19 infection rate) were analyzed and compared across the control and COVID-19 periods.ResultsThe total emergent urological patients during the COVID-19 period was 42, whereas during the control period, it was 124. The incidence of tube-related emergencies increased from 53% to 88% (P<0.001) during the COVID-19 period. In particular, the incidence of nephrostomy tube-related (31% vs. 15%, P=0.027) and single-J stent-related problems (19% vs. 6%, P=0.009) increased significantly. The mean surgery times across the two periods were comparable. The number of secondary complex operations increased from 12 (18%) to 14 (38%) (P=0.028) during the COVID 19-period. The number of 2-week postoperative readmission decreased from 10 (15%) to 1 (3%) (P=0.049). No participants contracted during the COVID-19 period.ConclusionsUrological tube-related emergencies have been found to have a higher incidence and require more complicated and dangerous operations during the COVID-19 pandemic. However, the optimized management strategies introduced in this study are efficient, and safe for both urologists and patients.     

经聚乙烯亚胺钝化的荧光碳点负载阿霉素抑制非小细胞肺癌细胞增殖、迁移侵袭的治疗研究

目的研究利用经聚乙烯亚胺（PEI）钝化的荧光碳点（CD）装载阿霉素（DOX）进行药物递送，旨在增加DOX对非小细胞肺癌的治疗作用，减少DOX的心肌毒性。 方法通过一步微波加热法将甘油和PEI的混合物制备成CD-PEI，并通过静电效应将DOX装载至CD-PEI。采用CCK8实验检测CD-PEI-DOX对非小细胞肺癌细胞A549的增殖能力的影响；Transwell实验评估CD-PEI-DOX对A549细胞迁移侵袭能力的影响；最后通过体内动物实验评估CD-PEI-DOX的心肌毒性以及对非小细胞肺癌皮下肿瘤生长的抑制效果。 结果体外细胞实验证实，对比单纯的DOX处理组，CD-PEI-DOX对非小细胞肺癌A549细胞增殖、迁移侵袭能力的抑制作用更为显著。体内实验证实，CD-PEI-DOX纳米复合物治疗组小鼠心肌细胞结构完整，并且能有效抑制小鼠皮下肺癌肿瘤的生长。 结论经PEI钝化的荧光碳点负载阿霉素能显著提高DOX对非小细胞肺癌的治疗效果，并减少DOX对心脏的毒性作用。运用CD-PEI纳米颗粒改善化疗药物递送的治疗方案取得了初步证实，这可为肺癌化学治疗提供新思路，具有广大的临床应用前景。
