Tasa de afectación de los márgenes quirúrgicos tras la cirugía conservadora de mama y estimación de los costes directos

ObjectiveAssessment of the reoperation rate in patients with positive resection margins after initial breast-conserving surgery for breast cancer and estimation of the cost to the hospital.Method146 patients with diagnosis of invasive breast cancer were included, who were initially intervened with conservative surgery by the Gynecology and Obstetrics Service of Hospital Universitario de Tarragona Juan XXIII (HUTJ23) during the years 2018 and 2019. We calculated the rate of involvement of the surgical margins of the resection piece after initial conservative surgery, establishing in which cases it was necessary to carry out a second resection, estimating the added direct costs of the second surgical procedure, and comparing them with the costs established by the Catalan Health Service according to the level of the hospital and the Diagnosis-Related Groups (DRG) established by the National Health System.ResultsThe rate of positive margins after initial conservative surgery was 20.55% and 19.17% patients underwent reoperation, generating a total expense of € 129.696,89, € 82.654,34 in conservative surgeries (€ 3.757,01 on average per patient) and € 47.042,55 in mastectomies (€ 6.720,36 on average per patient).ConclusionsMargin involvement after breast-conserving surgery is synonymous for reoperation, this involves a series of direct costs. It is advisable to control the factors related to affected margins to minimize their impact.     

ECFS standards of care on CFTR-related disorders: Updated diagnostic criteria

This paper is the first in a series providing updated guidance on the definition, evaluation and management of people with a Cystic Fibrosis Transmembrane conductance Regulator (CFTR)-Related Disorder (CFTR-RD). The need for this update relates to more precise characterisation of CFTR gene variants and improved assessment of CFTR protein dysfunction. The exercise is co-ordinated by the European CF Society Standards of Care Committee and Diagnostic Network Working Group and involves stakeholder engagement. This first paper was produced by a core group using an extensive literature review and papers graded for their quality. Subsequent wider stakeholder agreement was achieved.The definition of a CFTR-RD remains “a clinical condition with evidence of CFTR protein dysfunction that does not fulfil the diagnostic criteria for CF”. Clearer guidance on CFTR dysfunction and relevant CFTR variants will be provided. Thresholds for clinical presentations are presented and the paradigm that pathobiological processes may be evident in more than one organ is agreed. In this paper we reflect on the early patient journey, highlighting that CF specialists as well as other relevant specialists should be involved in the care of people with a CFTR-RD.     

微创性肺表面活性物质治疗新生儿呼吸窘迫综合征的疗效及肺部影像学表现

目的探讨微创性肺表面活性物质(LISA)治疗新生儿呼吸窘迫综合征(NRDS)的疗效及肺部影像学表现。方法择取郑州市第二人民医院于2018年3月至2021年2月收治的70例NRDS患儿,随机分为两组。对照组实行INSURE治疗方案,观察组采用LISA治疗方案,比较两组临床治疗情况、血气分析指标、不良反应事件及肺部影像学表现。结果两组二次PS使用率、给药成功率、NAPAP时间及住院时间比较,差异无统计学意义(P>0.05);而观察组72h内MV率为8.57%,低于对照组(28.57%,P<0.05);于T₂、T₃、T₄及T₅时点,两组PaO₂水平较T1时点均上升,PaCO₂、FiO₂水平则下降(P<0.05);于T₄、T₅时点,观察组FiO2水平低于对照组(P<0.05);两组不良反应及并发症发生率比较,差异均无统计学意义(P>0.05);经影像学特征分析,两组共计7例重度病症(“雪花征”样肺实变,已累及所有分区)、48例中度病症(“雪花征”样肺实变,尚未累及全部肺野)及15例轻度病症(呈“磨玻璃征”样肺实变,累计范围不限),经PS治疗6h、12h及24h后,给予LUS复查,两组NRDS患儿肺脏影像学评分均低于治疗前(P<0.05)。结论LISA及INSURE治疗NRDS均可起到较好疗效,但LISA整体获益更高,血气指标有一定改善,可降低72h内MV使用率,且不增加不良反应事件风险。     

飞秒激光辅助超声乳化联合Ahmed青光眼引流阀植入术治疗合并难治性青光眼的白内障

目的：评估飞秒激光辅助超声乳化联合Ahmed青光眼引流阀植入术治疗合并难治性青光眼的白内障的有效性和安全性。

方法：回顾性病例对照研究。2019-10/2021-10入院合并难治性青光眼的白内障患者53例53眼，依据自愿选择分为飞秒激光辅助白内障超声乳化(FLACS)组26例26眼和常规白内障超声乳化(CPCS)组27例27眼。两组分别行FLACS和CPCS联合Ahmed青光眼引流阀植入术。比较两组患者术中超声乳化能量释放量(CDE)、有效超声时间(EPT)的差异和术前与术后抗青光眼药物数量的变化，以及术后观察不同时期(1d，1wk，1、3mo)在提高最佳矫正视力(BCVA)，降低眼压、角膜内皮细胞损伤程度和手术并发症及成功率状况。

结果：FLACS组术中CDE和EPT明显低于CPCS组(t=8.50、5.16； P<0.01、=0.001)。两组术后抗青光眼药物较术前均明显减少(t=9.12、7.76； P=0.011、0.016)，但两组间无差异(t=1.79，P=0.082)。两组术后BCVA均较术前改善，眼压均较术前降低(P<0.05)。FLACS组在术后早期(1d，1wk)BCVA的改善较CPCS组更显著(t=9.74、8.49； P=0.008、0.012)，但在术后1、3mo的BCVA改善程度并无不同(t=0.62、0.44； P=1.415、2.021)。CPCS组在术后随访不同时期的角膜内皮细胞损伤较FLACS组更明显(P<0.05)。术后随访的不同时期FLACS组和CPCS组在控制眼压方面无差异(F_组间=0.64，P_组间=0.421)。FLACS组的手术并发症发生率27%(7/26)较CPCS组89%(24/27)低(χ²=20.95，P<0.01)，其中角膜水肿(8% vs 41%)、前囊撕裂(0 vs 11%)在FLACS组中明显低于CPCS组，后囊破裂(0 vs 7%)、玻璃体脱出(0 vs 4%)及人工晶状体偏位(0 vs 7%)也均发生在CPCS组。但两组的治疗总成功率相近(P=28.718)。

结论：飞秒激光辅助超声乳化联合Ahmed青光眼引流阀植入术可充分发挥联合手术的精准微创可控优势，帮助合并难治性青光眼的白内障患者有效降低眼压及更早获得视力恢复。
