BackgroundTo date, it remains unclear which patients with breast cancer (BC) benefit from post-mastectomy radiotherapy (PMRT). Cheng et al. developed and validated a scoring system based on 4 prognostic factors for locoregional recurrence (LRR) to identify patients in need for PMRT. These factors include age, estrogen receptor status, lymphovascular status and number of affected axillary lymph nodes.PurposeTo validate the scoring system for LRR in BC developed by Cheng et al. by using an independent BC database.Methods and materialsWe retrospectively identified 1989 BC cases, treated with mastectomy (ME) with or without PMRT at the University Hospitals Leuven between 2000 and 2007. The primary endpoint was 5-year locoregional control rate with and without PMRT, according to the LRR score.ResultsMedian follow-up time was 11.4 years. After excluding patients with missing variables 1103 patients were classified using the LRR scoring system: 688 (62.38%) patients were at low risk of recurrence (LRR score 0–1), 335 (30.37%) patients were at intermediate risk of recurrence (LRR score 2–3) and 80 (7.25%) patients were at high risk of recurrence (LRR score ≥4). 5-year locoregional control rates with and without PMRT were 99.20% versus 99.21% (p = 0.43) in the low-risk group; 98.24% versus 85.74% (p < 0.0001) in the intermediate-risk group and 96.87% versus 85.71% (p = 0.10) in the high-risk group respectively.ConclusionOur validation of the LRR scoring system suggests it can be used to point out patients that would benefit from PMRT. We recommend further validation of this scoring system by other independent institutions before application in clinical practice.  相似文献

BackgroundSevere primary graft failure is a life-threatening complication of heart transplantation that may require venoarterial extracorporeal membrane oxygenation (VA-ECMO) support. Surgical practices and management strategies regarding VA-ECMO vary between and within centers.MethodsWe performed a single-center retrospective cohort study on adult patients who received VA-ECMO for primary graft failure between 2013 and 2020. Clinical data were obtained from chart review and national databases. Patients were stratified by transplantation before or after 2017, when our center adopted additional objective criteria for VA-ECMO, adopted partial-flow support, and changed from central cannulation to chimney graft arterial cannulation of brachiocephalic, axillary, or aorta. The primary outcome was survival to device weaning. Secondary outcomes were survival to discharge, survival to 1 year, complications on support, and time to sedation weaning and extubation.ResultsFrom 276 heart transplant recipients, 39 severe primary graft failure patients requiring VA-ECMO were identified. Incidence of graft failure was 13% (n = 18 of 135) pre-2017 and 15% (n = 21 of 141) post-2017. Survival at all time points improved significantly after 2017, with greatest difference in survival to device weaning (61% pre-2017 vs 100% post-2017). After controlling for other factors in multivariable Cox regression modeling, transplantation after 2017 was a predictor of reduced mortality (hazard ratio, 0.209; 95% CI, 0.06-0.71; P = .01). Significant differences were not observed in other secondary outcomes of recovery.ConclusionsThe new VA-ECMO strategy displayed reasonable survival and a remarkable improvement from the prior system.  相似文献

BackgroundVenous thromboembolism (VTE) causes significant morbidity in pediatric trauma patients. We applied machine learning algorithms to the Trauma Quality Improvement Program (TQIP) database to develop and validate a risk prediction model for VTE in injured children.MethodsPatients ≤18 years were identified from TQIP (2017–2019, n = 383,814). Those administered VTE prophylaxis ≤24 h and missing the outcome (VTE) were removed (n = 347,576). Feature selection identified 15 predictors: intubation, need for supplemental oxygen, spinal injury, pelvic fractures, multiple long bone fractures, major surgery (neurosurgery, thoracic, orthopedic, vascular), age, transfusion requirement, intracranial pressure monitor or external ventricular drain placement, and low Glasgow Coma Scale score. Data was split into training (n = 251,409) and testing (n = 118,175) subsets. Machine learning algorithms were trained, tested, and compared.ResultsLow-risk prediction: For the testing subset, all models outperformed the baseline rate of VTE (0.15%) with a predicted rate of 0.01–0.02% (p < 2.2e−16). 88.4–89.4% of patients were classified as low risk by the models.High-risk predictionAll models outperformed baseline with a predicted rate of VTE ranging from 1.13 to 1.32% (p < 2.2e−16). The performance of the 3 models was not significantly different.ConclusionWe developed a predictive model that differentiates injured children for development of VTE with high discrimination and can guide prophylaxis use.Level of EvidencePrognostic, Level II.Type of StudyRetrospective, Cross-sectional.  相似文献

ObjectivesMinisternotomy and right anterior minithoracotomy are the 2 main techniques applied for minimally invasive aortic valve replacement. The goal of this study is to compare early and long-term outcomes of both techniques.MethodsThe data of 2419 patients undergoing isolated minimally invasive aortic valve replacement between 1999 and 2019 were prospectively collected. Retrospectively, patients were divided into the ministernotomy group (n = 1352) and the minithoracotomy group (n = 1067).ResultsAfter propensity score matching, 986 patients remained in each group. Operation time and rate of conversion to full sternotomy were significantly higher in the minithoracotomy group than in the ministernotomy group (184.6 ± 45.2 vs 241.3 ± 68.6, relative risk, 2.54, P = .005 and .09 vs .23, relative risk, 1.45, P = .013, respectively). The 30-day mortality, excluding cardiac death, was lower in the ministernotomy group than in the minithoracotomy group (0.012 vs 0.028, relative risk, 1.41, P = .011, respectively); the intensive care unit length of stay (12.4 vs 16.5, relative risk, 1.62, P = .037, respectively) and hospital length of stay (5.4 vs 8.7, relative risk, 1.74 P = .028, respectively) were significantly longer in the minithoracotomy group. The minithoracotomy surgical approach was the strongest independent predictor of early mortality (odds ratio, 4.24 [1.67-7.35], P = .002). The actuarial survival by Kaplan–Meier analysis at 1, 3, 5, 10, and 20 years was significantly better in the ministernotomy group than in the minithoracotomy group (P = .0001). Actuarial freedom from reoperation at 5 years was 97.3% ± 4.4% in the ministernotomy group versus 95.8% ± 5.2% in the minithoracotomy group (P = .087).ConclusionsMinimally invasive aortic valve replacement using ministernotomy is associated with reduced operative time, intensive care unit stay, hospital length of stay, and postoperative morbidities and incisional pain, and improves early and long-term mortality.  相似文献

IntroductionThe Nuss repair for pectus excavatum is associated with significant postoperative pain. Our institution developed protocols to standardize pain management for pectus excavatum patients in the immediate postoperative period. We present our experience with protocol implementation and patient outcomes.MethodsWe standardized regional anesthesia with a 0.25% bupivacaine incisional soaker catheter (post-implementation 1, PI1) before transitioning to intercostal nerve cryoablation (INC) (post-implementation 2, PI2). Patient outcomes were tracked using statistical process control charts in AdaptX™ OR Advisor and run charts in Tableau. Chi-squared tests assessed demographic differences between cohorts.Results244 patients were included: 78 pre-implementation, 108 PI1, and 58 PI2. Average age was 15.9–16.5 years. Patients were majority male, non-Hispanic white, and English speaking. Hospital length of stay decreased 4.1–2.4 days. INC increased surgery time (99–125 min) but decreased PACU time (112-78 min). Maximum pain scores improved in PACU (7.7–6.0) and 0–24 h postoperatively (8.3–6.8) but were not different 24–48 h postoperatively (5.4–5.8). Average opioid dosing decreased 0–48 h from 1.9 to 0.8 mg/kg morphine milliequivalents and was associated with reduction in post-operative nausea and constipation. There were no 30-day readmissions.ConclusionAn institution-wide pain management protocol using INC for pectus excavatum patients was implemented. Intercostal nerve cryoablation was found to be superior to bupivacaine incisional soaker catheters and reduced hospital length of stay, immediate postoperative pain scores, morphine milliequivalent opioid dosing, postoperative nausea, and constipation.Level of EvidenceLevel IV.  相似文献

BackgroundPrealbumin is a more sensitive serum biomarker in reflecting liver function and nutritional status than albumin, because of its shorter half-life and its characteristics that could hardly be affected by supplemental venous infusion of albumin or blood transfusion. This study aimed to identify whether preoperative prealbumin level was associated with postoperative mortality and morbidity after hepatic resection for patients with hepatocellular carcinoma (HCC).MethodsFrom a Chinese multicenter database, patients who underwent hepatic resection for HCC were divided into the low and normal prealbumin groups by using 17 mg/dL as the cut-off level for serum prealbumin taken within a week before surgery. Using univariable and multivariable logistic regression analyses, independent predictors associated with postoperative 30-day and 90-day mortality, 30-day overall and major morbidity, and postoperative hepatic insufficiency were identified.ResultsAmong 1356 patients, 409 (30.2%) had a low preoperative prealbumin level. Postoperative 30-day and 90-day mortality, and 30-day overall and major morbidity in the low prealbumin group were significantly higher than the normal prealbumin group (2.9% vs. 0.5%, 5.1% vs. 1.5%, 35.7% vs. 18.4%, and 14.4% vs. 6.5%, respectively, all P < 0.001). Multivariable analyses identified that preoperative prealbumin level, but not albumin level, was independently associated with postoperative 30-day mortality (OR: 3.486, 95% CI: 1.184–10.265), 90-day mortality (2.504, 1.219–5.145), 30-day overall morbidity (1.727, 1.302–2.292), 30-day major morbidity (1.770, 1.155–2.711) and postoperative hepatic insufficiency (1.967, 1.119–3.427).ConclusionsPreoperative prealbumin level could be used to predict postoperative morbidity and mortality for patients treated with hepatic resection for HCC.  相似文献
