Partial nephrectomy should be classified as an inpatient procedure: Results from a statewide quality improvement collaborative

ObjectivesTo examine length of stay (LOS) and readmission rates for all minimally-invasive partial nephrectomy (MIPN) and MI radical nephrectomy (MIRN) performed for localized renal masses ≤7 cm in size (cT1RM) within 12 Michigan urology practices. Both RN and PN are commonly performed in treating cT1RM. Although technically more complex and associated with higher complication rates, Centers for Medicare & Medicaid Services considers MIPN an outpatient procedure and MIRN is inpatient.MethodsWe collected data for renal surgeries for cT1RM at MUSIC-KIDNEY practices between May 2017–February 2020. Data abstractors recorded clinical, radiographic, pathologic, surgical, and short-term follow-up data into the registry for cT1RM patients.ResultsWithin MUSIC-KIDNEY, 807 patients underwent MI renal surgery at 12 practices. Median LOS for cT1RM patients after MIPN (n = 531, 66%) was 2 days and after MIRN (n = 276, 34%) was also 2 days. Among patients undergoing laparoscopic or robotic PN, 171 (32%), 230 (43%), and 130 (24%) stayed ≤1, 2, ≥3 days. Among patients undergoing laparoscopic or robotic RN, 81 (29%), 112 (41%), and 83 (30%) stayed ≤1, 2, ≥3 days. No significant difference was observed between MIPN and MIRN on LOS commensurate with outpatient surgery (≤1-day, OR = 0.97, P = 0.87).ConclusionsLess than one-third of patients had a LOS ≤1-day and LOS was comparable for MIPN and MIRN. Centers for Medicare & Medicaid Services should be advised that MIPN is a more complex surgery than MIRN, most patients receiving a MIPN will require a ≥2-day hospital stay and it would be more appropriate to classify MIPN an inpatient procedure with MIRN.

隆突性皮肤纤维肉瘤20例临床病理分析

20例隆突性皮肤纤维肉瘤临床特点为发生于真皮内、病程长、常反复局部复发。组织学特征为梭形瘤细胞围绕小血管排列成车辐状结构且遍及整个瘤体;瘤细胞成分单一、核轻度异型、核分裂象少见;瘤体常包裹较多脂肪细胞和皮肤附件;瘤组织常向皮下脂肪呈树枝状浸润性生长。本文介绍了新近的色素型和纤维肉瘤型两个亚型。     

腺苷脱氨酶抑制剂对氧反常大鼠心脏的保护作用

本文观察到腺苷脱氨酶抑制剂EHNA对离体灌流大鼠心脏氧反常性损伤有明显的作用,此外还发现在缺氧期(无氧灌流30分钟)EHNA也表现出明显的保护作用,心脏收缩幅度的降低和静息张力的升高均显著低于对照组。表明在缺氧期也可能有自由基的产生。     

兔中性粒细胞防御素对HL—60细胞毒性及对病毒的直接灭活作用

本研究从新西兰家兔腹腔渗出中性粒细胞溶酶体内提取酸溶性组分，经制备性ＡＵ－ＰＡＧＥ获得纯化的防御素（ＮＰ１和ＮＰ２），ＳＤＳ－ＰＡＧＥ测定分子量为３ｋｄ左右。以ＨＬ－６０细胞作靶细胞，当ＮＰ１或ＮＰ２在１００μｇ／ｍｌ浓度时，可杀死６０％以上的ＨＬ－６０细胞。ＮＰ１（２６０μｇ／ｍｌ）还可直接灭活单纯疱疹病毒Ｉ型和乙型流感病毒，分别使病毒感染滴度降度９８．２％和９０％。本研究结果提示，中性粒细胞可     

顺铂术中腹腔化疗对妇科恶性肿瘤患者术后的近期影响

目的 探讨顺铂术中腹腔化疗治疗妇科恶性肿瘤的可行性。方法 60例妇科恶性肿瘤患者术中腹腔置入100mg顺铂稀释液,观察其对患者术后胃肠功能、体温、切口愈合、腹水控制及术后并发症的影响。结果 术后24h内呕吐发生率增高,但使用止吐剂及水化效果好,尿量达标;胃肠道功能按期恢复;术后发热发生率低;服务部切口无一例丙级愈合;无并发症发生。14例伴发大量腹水患者11例得到控制。肝肾功能未发现损害。结论 术中腹腔化疗比较安全,切实可行。     

内皮素与脑梗死

目的 :检测脑梗死病人的内皮素 - 1(ET - 1)水平 ,研究ET - 1与脑梗死的关系。方法 :检测脑梗死病人ET - 1的水平 ,并与正常对照组比较。结果 :脑梗死病人的ET - 1明显高于正常对照组水平 (U =13.45 ,P<0 0 1) ,还发现ET - 1与高血压、糖尿病、高血脂症有一定的关系。结论 :ET - 1的增高是脑梗死发病的内源性危险因素之一 ,ET - 1的增高不但与脑梗死的发病有关而且与脑梗死的发展有关
