Objective
Comparative survival between neoadjuvant chemotherapy and adjuvant chemotherapy for patients with cT2-4N0-1M0 non–small cell lung cancer has not been extensively studied.Methods
Patients with cT2-4N0-1M0 non–small cell lung cancer who received platinum-based chemotherapy were retrospectively identified. Exclusion criteria included stage IV disease, induction radiotherapy, and targeted therapy. The primary end point was disease-free survival. Secondary end points were overall survival, chemotherapy tolerance, and ability of Response Evaluation Criteria In Solid Tumors response to predict survival. Survival was estimated using the Kaplan–Meier method, compared using the log-rank test and Cox proportional hazards models, and stratified using matched pairs after propensity score matching.Results
In total, 330 patients met the inclusion criteria (n = 92/group after propensity-score matching; median follow-up, 42 months). Five-year disease-free survival was 49% (95% confidence interval, 39-61) for neoadjuvant chemotherapy versus 48% (95% confidence interval, 38-61) for adjuvant chemotherapy (P = .70). On multivariable analysis, disease-free survival was not associated with neoadjuvant chemotherapy or adjuvant chemotherapy (hazard ratio, 1.1; 95% confidence interval, 0.64-1.90; P = .737), nor was overall survival (hazard ratio, 1.21; 95% confidence interval, 0.63-2.30; P = .572). The neoadjuvant chemotherapy group was more likely to receive full doses and cycles of chemotherapy (P = .014/0.005) and had fewer grade 3 or greater toxicities (P = .001). Response Evaluation Criteria In Solid Tumors response to neoadjuvant chemotherapy was associated with disease-free survival (P = .035); 15% of patients receiving neoadjuvant chemotherapy (14/92) had a major pathologic response.Conclusions
Timing of chemotherapy, before or after surgery, is not associated with an improvement in overall or disease-free survival among patients with cT2-4N0-1M0 non–small cell lung cancer who undergo complete surgical resection. 相似文献2.

Nursing schools strive to select a diverse student population who are likely to succeed by ensuring timely student progression through the program and effective use of educational sources. The purpose of this systematic literature review is to explore the preadmission variables and selection criteria that predict student success in 4-year baccalaureate nursing programs in the U.S. Sixteen articles met the eligibility criteria, and six measures were used to define student success: (a) early academic success, particularly during the first and second year; (b) attrition; (c) timely completion of the program; (d) graduation; (e) performance in nursing courses; and (f) academic performance in other science courses. Typically, the core set of cognitive predictors used in the admission process in nursing schools were pre-nursing GPA, pre-nursing collegiate science GPA, and scores on standardized aptitude exams. This review suggests that it is challenging to isolate one single variable as the best predictor of student success; however, using a combination of variables can offer a reliable prediction method. More researchers should consider using a theoretical basis to guide their inquiry on this topic. Additionally, researchers should examine admission variables that are most relevant across programs. 相似文献

Purpose
To evaluate the feasibility of a same-day yttrium-90 (90Y) radioembolization protocol with resin microspheres (including pretreatment angiography, lung shunt fraction [LSF] determination, and radioembolization) for the treatment of hepatocellular carcinoma (HCC) and liver metastases.Materials and Methods
All same-day radioembolization procedures performed over 1 y (February 2017 to January 2018) were included in this single-institutional retrospective analysis, in which 34 procedures were performed in 26 patients (median age, 63 y; 13 women), 19 with liver metastases and 7 with HCC. Yttrium-90 treatment activities were calculated by body surface area method. Tumor imaging response was assessed by Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 for liver metastases and modified RECIST for HCC. Clinical side effects and adverse events were graded per Common Terminology Criteria for Adverse Events version 4.0.Results
All planned cases were technically successful, and no cases were canceled for elevated LSF or vascular anatomic reasons. Pretreatment angiography modified the planned 90Y treatment activity in 1 case in which vascular anatomy required a lobar-dose split into 2 for segmental infusions. In 18% of cases, patients were briefly admitted after the procedure for observation or symptom management. Imaging evaluation of initial efficacy at 1 month demonstrated partial response in 25% and stable disease in 67% of patients with liver metastases and partial/complete response in 43% and stable disease in 14% of patients with HCC. Grade ≥ 3 adverse events occurred in 6% of cases, with no systemic therapy–limiting toxicities. The mean total procedure time was 4.2 hours.Conclusions
A same-day 90Y radioembolization protocol with resin microspheres is feasible in select patients, which can expedite cancer therapy. 相似文献5.

We calculated a Research Diagnostic Criteria (RDC) endogenous score for 257 depressed inpatients based on the number of endogenous criteria present. The distribution of RDC endogenous scores was unimodal. There was no association between endogenous scores and results of the Dexamethasone Suppression Test, or morbid risk for depression in the patients' first-degree relatives. The morbid risk for a family history of alcoholism tended to decrease with increasing endogenous scores, although a consistent steady decline was not observed. The results suggest that the RDC criteria do not fit either the categorical or dimensional model of endogenous classification. Potential sources of difficulty with the RDC endogenous criteria are discussed. 相似文献

A structured interview was used to examine the 1-year incidence and prevalence of depression among 116 first-year university students. While 24 of the subjects (20.7%) met the Diagnostic and Statistical Manual of Mental Disorders 4th ed. (DSM-IV) criteria for Major Depressive Episode (MDE), 62 (53.4%) met the Diagnostic and Statistical Manual of Mental Disorders 3rd ed. Revised (DSM-III-R) criteria for MDE, and 27 (23.3%) also met the Research Diagnostic Criteria (RDC) for Major Depressive Disorder (MDD) for the 12 months prior to the interview. Moreover, 23 of the subjects (19.8%) had onset of the DSM-IV criteria for MDE, 54 (46.6%) had onset of the DSM-III-R criteria for MDE, 24 (20.7%) had onset of the RDC for MDD, during the same time period. These high rates of depression may be explained by the students' difficulties in and by their readjustment after entering university. 相似文献

目的 了解原发性肾病综合征患儿激素效应状况及不同激素效应患儿的临床特点和预后.方法 回顾性分析北京大学第一医院1993年1月至2012年12月原发性肾病综合征(24h尿蛋白定量≥50 mg/kg,血浆清蛋白<25 g/L)患儿的临床资料.纳入随访1年以上者,根据患儿对足量激素的效应分为4周内转阴组、4~8周转阴组和8周耐药组.比较各组性别、年龄、临床表型、并发症、激素不良反应和严重预后(慢性肾功能不全、肾移植或死亡)发生情况的差异.结果 共1 059例患儿符合原发性肾病综合征,激素效应明确者841例,其中4周以内转阴者603例(71.7%,603/841例),4~8周转阴者34例(4.0%,34/841例),8周未转阴者204例(24.3%,204/841例),初次治疗尿蛋白平均转阴时间(13.2±8.9)d,中位转阴时间10.0 d.对随访病程1年以上的369例行进一步分析,4周内转阴组276例(74.8%,276/369例),4~8周转阴组18例(4.9%,18/369例),8周耐药组75例(20.3%,75/369例).3组性别分布相似,起病年龄差异有统计学意义(P<0.01),4周内转阴组、4~8周转阴组和8周耐药组起病年龄分别为(5.2±3.3)岁、(5.7±3.3)岁和(6.6±3.8)岁.4~8周转阴组(单纯型83.3%,15/18例)与4周内转阴组(单纯型95.3%,263/276例)均以单纯型为主,与8周耐药组(单纯型45.3%,34/75例)比较差异有统计学意义(P<0.01).4~8周转阴组(11.1%,2/18例)与4周内转阴组(4.3%,12/276例)及8周耐药组(0)比较,急性肾上腺皮质功能不全发生率差异有统计学意义(P=0.04).3组间其余激素不良反应发生率比较差异无统计学意义.4周内转阴组(1.4%,4/276例)、4~8周转阴组(0)和8周耐药组(16.0%,12/75例)比较,严重预后发生率差异有统计学意义(P<0.01).结论 71.7%的原发性肾病综合征患儿在足量激素治疗4周内尿蛋白转阴,4周内尿蛋白未转阴者14.3%的患儿继续足量激素治疗可能在8周内转阴,其余患儿即使足量激素治疗8周尿蛋白亦不能转阴.足量激素治疗8周内转阴患儿以单纯型为主,预后较好,8周耐药者以肾炎型为主,预后较差.对于足量激素治疗4~8周内转阴的患儿需警惕急性肾上腺皮质功能不全的风险. 相似文献
