BackgroundHepatopancreatobiliary (HPB) surgery fellowship training has multiple paths. Prospective trainees and employers must understand the differences between training pathways. This study examines self-reported fellowship experiences and current scope of practice across three pathways.MethodsAn online survey was disseminated to 654 surgeons. These included active Americas Hepato-Pancreato-Biliary Association (AHPBA) members and recent graduates of HPB, transplant–HPB and HPB–heavy surgical oncology fellowships.ResultsA total of 416 (64%) surgeons responded. Most respondents were male (89%) and most were practising in an academic setting (83%). 290 (70%) respondents underwent formal fellowship training. Although fellowship experiences varied, current practice was largely similar. Minimally invasive surgery (MIS) and ultrasound were the most commonly identified areas of training deficiencies and were, respectively, cited as such by 47% and 34% of HPB-, 49% and 50% of transplant-, and 52% and 25% of surgical oncology-trained respondents. Non-HPB cases performed in current practice included gastrointestinal (GI) and general surgery cases (56% and 49%, respectively) for HPB-trained respondents, transplant and general surgery cases (87% and 21%, respectively) for transplant-trained respondents, and GI surgery and non-HPB surgical oncology cases (70% and 28%, respectively) for surgical oncology-trained respondents.ConclusionsFellowship training in HPB surgery varies by training pathway. Training in MIS and ultrasound is deficient in each pathway. The ultimate scope of non-transplant HPB practice appears similar across training pathways. Thus, training pathway choice is best guided by the training experience desired and non-HPB components of anticipated practice. 相似文献
There is an increasing incidence of elderly patients requiring emergency laparotomy. Our study compares the outcomes of elderly patients undergoing emergency laparotomy against the outcomes of non-elderly patients.
Methodology
Patients who underwent emergency laparotomy between 2015 and 2017 from the National University Hospital, Singapore, were included. Apart from demographic data, indication of surgery and surgical procedure performed were collected. Prospectively collected nutritional scores were evaluated. Outcome measures included duration of surgery, length of ICU and total hospital stay, post-operative complications, and mortality indices. We performed multivariate Cox regression analysis to determine the contribution of various risk factors towards overall survival following emergency laparotomy.
Results
A total of 170 emergency laparotomies were performed. Compared to non-elderly patients, elderly patients had a significantly longer mean stay in hospital (31.5 vs. 18.6 days, p = 0.006) and mean stay in ICU (13.1 vs. 5.3 days, p = 0.003). More elderly patients suffered from post-laparotomy complications compared with non-elderly patients (65.8% vs. 37.4%, p < 0.001). 30-day mortality (31.5% vs. 8.8%, p = 0.019) and 1-year mortality (27.9% vs. 14.3%, p = 0.023) were higher in elderly patients compared with non-elderly patients. Interestingly, there was no statistically significant difference between elderly and non-elderly groups in both the global 3-MinNS as well as the global SGA nutritional scores. ASA status (HR 2.61, 95% CI 1.05–6.45, p = 0.038) was an independent risk factor for decreased survival following emergency laparotomy. Notably, while age ≥ 65 demonstrated a significant correlation with survival on univariate analysis (HR 1.03 (1.01–1.05), p = 0.003), this effect was lost following multivariate regression (HR 1.01 (0.453–2.23), p = 0.989).
Conclusion
Elderly patients suffer worse morbidity and mortality following emergency laparotomy. This is likely contributed by comorbidities resulting in higher ASA status.
目的 研究miR-200、miR-155及血管新生因子与原因不明复发性流产(unexplained recurrent spontaneousabortion,URSA)的相关性分析。 方法 选择2015年3月—2018年1月在青岛市妇女儿童医院妇产科就诊的URSA患者作为URSA组、要求终止妊娠的正常早孕患者作为对照组,检测绒毛组织中微小RNA(microRNA, miR)miR-200、miR-155、血管内皮生长因子(vascular endothelial growth factor,VEGF)、可溶性FMS样酪氨酸激酶1(soluble FMS like tyrosine kinase-1,sFlt-1)的表达量及血清中VEGF、sFlt-1的含量,对miR-200、miR-155靶向结合VEGF、sFlt-1进行生物信息学分析。 结果 URSA组的绒毛组织中miR-200(1.78±0.32 vs. 0.91±0.15)、sFlt-1(1.87±0.35 vs. 1.06±0.21)的相对表达量及血清中sFlt-1的含量[(12.39±2.31)ng/ml vs. (6.51±0.95)ng/ml]均高于对照组,差异有统计学意义(均P<0.05)。绒毛组织中miR-155相对表达量(0.60±0.10 vs. 0.93±0.16)、VEGF mRNA相对表达量(0.59±0.09 vs. 1.02±0.16)及蛋白表达量(0.62±0.07 vs. 1.04±0.18)、血清中VEGF的含量[(601.25±94.39)ng/ml vs. (935.12±132.47)ng/ml]低于对照组,差异有统计学意义(均P<0.05);URSA组患者绒毛组织中miR-200的表达量与血清中VEGF的含量、绒毛组织中VEGF的表达量均呈负相关,绒毛组织中miR-155的表达量与血清中sFlt-1的含量和绒毛组织中sFlt-1的表达量均呈负相关;miR-200、miR-155分别靶向结合VEGF、sFlt-1基因的3’UTR。 结论 miR-200表达增多、miR-155表达减少与URSA发生有关,miR-200靶向VEGF、miR-155靶向sFlt-1是介导该过程的可能机制。 相似文献
