基于龋风险评估的龋病治疗计划

随着对龋病病因及发病机制的深入认识,龋病的治疗不应局限于对现有龋损的修复治疗,而应以龋病风险评估和龋损活跃性评估为基础,以患者为中心,制定个性化的治疗方案,恢复口腔微生态平衡,进而控制龋病进展和恢复患牙的结构与功能。

以专培学员为主导的CBL教学对心血管专培学员自身综合能力提升的影响

心血管专科医师规范化培训目标要求高于住院医师培训，完成心血管专培的医生应能在医疗、教学、科研能力上明显提高，达到心血管专科主治医师水平。如何提高心血管专培学员教学能力是专培中的难点。将专培学员随机分为两组,分别采用案例教学法（case-based learning, CBL）和传统教学法进行带教,课程结束后通过测验和调查问卷两种方式对教学效果进行考察。旨在探讨由心血管专培学员主导CBL教学法在实施过程中是否对其自身综合能力有所提升。结果显示，CBL教学法组学生临床理论及病例分析考试分数均高于对照组；心血管专培学员通过主导CBL教学，在教学能力、组织能力和学科协调均有提升；相较传统教学法,CBL教学法的教学效果更佳,有利于心血管专培学员自身综合能力提升。     

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.

     

生化汤加味促进剖宫产后子宫复旧随机对照试验的系统评价及Meta分析＊

目的 对生化汤加味促进剖宫产后子宫复旧的有效性与安全性进行系统评价，为其在临床应用提供循证医学证据。方法 检索中国生物医学文献数据库（CBM）、中国知网（CNKI）、万方资源数据库（WanFang）、维普期刊数据库（VIP）、Cochrane Library、PubMed、Web of Science等，检索时限为建库至2020年7月，选择生化汤加味促进剖宫产后子宫复旧的随机对照试验（RCT），采用Cochrane系统评价员手册提供的偏倚风险评估工具进行文献质量评价，应用RevMan5.3软件进行Meta分析。结果 共纳入12篇RCT文献，共计1804例剖宫产产妇；Meta分析结果显示，生化汤加味联合缩宫素组在产后第1、3、5天子宫底高度［MD = -0.75，95%CI（-1.35， -0.15），P < 0.00001；MD = -1.92，95%CI（-3.13， -0.72），P < 0.00001；MD = -1.92，95%CI（-3.79， -0.06），P < 0.00001］低于单用缩宫素组，联合用药组血性恶露时间［MD = -1.52，95%CI（-2.71，-0.34），P < 0.00001］和产后恶露持续时间［MD = -4.47，95%CI（-6.20，-2.75），P < 0.00001］均短于单用缩宫素组。结论 生化汤加味联合缩宫素与单用缩宫素比较，更能促进产后子宫复旧；不良反应少，报道的仅有4例出现轻微腹泻，安全性较高；但由于纳入文献质量较低，上述结论尚需更多的随机对照临床研究加以证实。     

Outcomes and risk management in type B aortic dissection patients with acute kidney injury: a concise review

PurposeType B aortic dissection is a rare but life-threatening disease. Thoracic endovascular aortic repair (TEVAR) was widely used for Type B aortic dissection patients in the last decade due to the lower mortality and morbidity compared with open chest surgical repair (OCSR). AKI in type B aortic dissection is a well-recognized complication and indicates poor short-term and long-term outcome. The objective of this concise review was to identify the risk factors and the impact of AKI on type B aortic dissection patients.Methods and resultsA literature search was performed using PubMed, Embase, MEDLINE, and Cochrane Library with the search terms ‘type B aortic dissection’ and ‘acute kidney injury’ (AKI), and all English-language literatures published in print or available online from inception through August 2020 were thoroughly reviewed. Studies that reported relative AKI risks and outcomes in type B aortic dissection patient were included. Major mechanisms of AKI in type B aortic dissection included renal hypoperfusion, inflammation response, and the use of contrast medium. Type B aortic dissection patients with AKI significantly had increased hospital stay duration, need of renal replacement therapy, and 30-d and 1-year mortality.ConclusionsAKI in type B aortic dissection is a well-recognized complication and associated with poor short-term and long-term outcome. Early identification of high-risk patients, early diagnosis of AKI, stabilization of the hemodynamic parameters, avoidance of nephrotoxic drugs, and optimization of the use of contrast agents are the major strategies for the reduction of AKI in type B aortic dissection patients.

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.
