基于Ridit和RSR法的临床手术科室风险系数及其风险等级评价

目的探寻构建临床手术科室风险系数并客观评价其风险等级的方法。方法结合Ridit法与RSR法,对临床手术科室风险系数进行分档评级。结果手术科室风险系数(Ki)=各科室平均Ridit值+三四级手术占比+复杂病人占用床日比。后期通过运用RSR法和最佳分档准则,将Ki值分为3档,即临床手术科室风险分为3个等级:第一级为低风险科室,第二级为一般风险科室,第三级为高风险科室。结论利用临床手术科室风险系数Ki值反映各科承担的手术风险,能相对客观公正地表现临床医生的工作量和工作强度,有利于优化医院内部运营绩效考核与分配等工作。     

Pathological characterisation of male breast cancer: Results of the EORTC 10085/TBCRC/BIG/NABCG International Male Breast Cancer Program

AimSeveral prognostic histological features have been established in female breast cancer (BC), but it is unknown whether these can be extrapolated to male BC patients. The aim of this study was to evaluate the prognostic value of several histological features in a large series of male BC.MethodsCentral pathology review was performed for 1483 male BCs collected through part 1 of the European Organisation for Research and Treatment of Cancer (EORTC) International Male BC Program. Pathology review included histological subtype, grade, mitotic activity index (MAI), presence of a fibrotic focus and density of tumour-infiltrating lymphocytes (TILs). These features were correlated with clinical outcome. The relationship between these features and surrogate molecular subtypes using immunohistochemistry was also assessed.ResultsMedian follow-up for overall survival (OS) was 7.1 years. Overall histological grade was not significantly associated with OS (p = 0.129). MAI, the presence of a fibrotic focus and a low TIL density however were correlated with unfavourable OS (p = 0.023, p = 0.004 and p = 0.011, respectively). BC subtype correlated with TIL density (p = 0.015), as we observed a higher density for human epidermal growth factor receptor type 2 (HER2) positive BC compared to luminal HER2-negative subtype. No association was observed between subtype and fibrotic focus.ConclusionsHistologic grade was not significantly correlated with clinical outcome in this series, unlike what is seen in female patients. These results contribute to our understanding of male BC and indicate the importance of further research on the optimisation of risk stratification and treatment decisions for male BC patients.

Validation of a semi‐automatic co‐registration of MRI scans in patients with brain tumors during treatment follow‐up

There is an expanding research interest in high‐grade gliomas because of their significant population burden and poor survival despite the extensive standard multimodal treatment. One of the obstacles is the lack of individualized monitoring of tumor characteristics and treatment response before, during and after treatment. We have developed a two‐stage semi‐automatic method to co‐register MRI scans at different time points before and after surgical and adjuvant treatment of high‐grade gliomas. This two‐stage co‐registration includes a linear co‐registration of the semi‐automatically derived mask of the preoperative contrast‐enhancing area or postoperative resection cavity, brain contour and ventricles between different time points. The resulting transformation matrix was then applied in a non‐linear manner to co‐register conventional contrast‐enhanced T₁‐weighted images. Targeted registration errors were calculated and compared with linear and non‐linear co‐registered images. Targeted registration errors were smaller for the semi‐automatic non‐linear co‐registration compared with both the non‐linear and linear co‐registered images. This was further visualized using a three‐dimensional structural similarity method. The semi‐automatic non‐linear co‐registration allowed for optimal correction of the variable brain shift at different time points as evaluated by the minimal targeted registration error. This proposed method allows for the accurate evaluation of the treatment response, essential for the growing research area of brain tumor imaging and treatment response evaluation in large sets of patients.

What Factors Predict Patient Dissatisfaction After Contemporary Medial Opening-Wedge High Tibial Osteotomy?

BackgroundAlthough current advances in surgical techniques have improved outcomes of the medial opening-wedge high tibial osteotomy (MOWHTO), the factors associated with patient dissatisfaction remain unclear. Thus, the purpose of this study is to identify risk factors for patient dissatisfaction following contemporary MOWHTO.MethodsWe retrospectively reviewed prospectively collected data on 140 consecutive MOWHTO patients using an anatomical locking plate with a minimum follow-up of 2 years. Patient demographics, pain Visual Analogue Scale, Western Ontario and McMaster Universities Osteoarthritis Index, Kellgren-Lawrence (K-L) grade, activity level, articular cartilage and meniscal status, hip-knee-ankle angle, change in alignment, and postoperative weight-bearing line ratio were recorded. Patients were categorized using the New Knee Society Score into satisfied (satisfaction score ≥20) or dissatisfied (satisfaction score <20) groups. Patient and surgical factors were compared between the groups by the identified predictors. Multiple logistic regression analysis was used to analyze risk factors, including K-L grade IV medial osteoarthritis (OA), preoperative pain Visual Analogue Scale, total Western Ontario and McMaster Universities Osteoarthritis Index score, postoperative hip-knee-ankle angle, change in alignment, and partial meniscectomy.ResultsOf the 140 patients, 24 (17.1%) were dissatisfied with their results. Multiple logistic regression analysis showed that only K-L grade IV medial OA was statistically associated with patient dissatisfaction following MOWHTO (odds ratio 4.911, 95% confidence interval 1.820-13.256, P < .01).ConclusionSevere medial OA was an independent risk factor for dissatisfaction following contemporary MOWHTO using a rigid locking plate. Surgeons should take this into consideration when counseling and choosing surgical options in MOWHTO candidates with severe medial OA.Level of EvidenceLevel III.     

Asociación entre el dolor abdominal y el grado de coproestasis mediante la evaluación radiográfica en pacientes estreñidos que acuden a los servicios de urgencias pediátricas

Introduction and aimAbdominal pain in children is a frequent cause of emergency room consultation. An important group of those patients presents with chronic constipation and fecal impaction. Plain abdominal x-ray is widely used for making a diagnosis and ruling out the need for surgical treatment. The present study examined the association between pain intensity and fecal impaction grade.Materials and methodsAn analytic cross-sectional study was conducted that compared 2 radiographic scales to determine the association between the grade of fecal impaction observed and abdominal pain intensity in patients that sought medical attention at an emergency service within a 7-month period. The analysis was carried out by 2 different observers, utilizing 2 different radiographic scales to confirm their reproducibility. The degree of interobserver agreement was measured using the Kappa coefficient and the association between abdominal pain and fecal impaction grade was measured through the Spearman correlation coefficient.ResultsThere was a significant association between pain intensity and the radiographic grade of fecal impaction (P < .05) for the radiographic scale by segments and its interobserver agreement was high, compared with the scale by percentage.ConclusionsRadiographic scales may be useful in the evaluation and treatment of patients with abdominal pain and constipation. The segmental scale showed less interobserver variability, suggesting its proposal as an alternative in the evaluation and follow-up of patients with chronic constipation.     

多模态MRI在子宫内膜癌术前风险分层中的应用进展

子宫内膜癌（EC）的预后因素包括肿瘤FIGO分期、肌层侵犯深度、淋巴血管间隙浸润，肿瘤的病理分级，以及淋巴结转移与否。筛选高危患者术中淋巴结清扫，避免低危患者过度治疗，具有重要的临床意义。目前，MRI是EC 术前分期最有价值的检查手段之一，磁共振扩散加权成像、体素内不相干运动、MR 动态增强扫描以及MR 影像组学分析等多模态技术均已用于EC 的术前风险评价。本文将对多模态MRI 在EC 术前风险分层中的应用进展进行综述。
