Background and Aims. The insertion of the guidewires (GWs) into the pancreatic duct is technically difficult, and there is a risk of post-ERCP pancreatitis (PEP). The aim of this study was to evaluate the safety and efficacy of a small J-tipped guidewire for pancreatic duct endoscopic intervention. Methods. This single-site retrospective study was conducted to assess the procedural success rate and adverse events of endoscopic transpapillary interventions to the pancreatic duct in 114 cases using the small J-tipped GW and 180 cases using the angle-tipped GW. Results. The procedural success rate was significantly higher in the small J-tipped GW group compared with that in the angle-tipped GW group (76% versus 47%, P < 0.001). The procedural success-related factors were chronic pancreatitis (OR 0.43, 95% CI 0.22–0.82, P = 0.01), flexion angle of the pancreatic duct < 90° (OR 0.50, 95% CI 0.30–0.80, P = 0.01), and use of the small J-tipped GW (OR 4.63, 95% CI 2.61–8.20, P < 0.001). The rates of total post-ERCP pancreatitis were significantly lower in the small J-tipped GW group compared with that in the angle-tipped GW group (3.5% versus 12.2%, P = 0.01). Multivariate analysis of pancreatitis risk factors indicated that only the use of the small J-tipped GW was a factor in decreasing the risk of developing pancreatitis (OR 0.12, 95% CI 0.09–0.85, P = 0.02). Conclusions. Small J-tipped GWs increase the success rate of the pancreatic duct endoscopic intervention as well as a reduced risk of developing postoperative pancreatitis.

Introduction: Dilation of the track can be achieved by multiple incremental flexible Amplatz type, Alken metal telescoping dilators, or balloon in Percutaneous Nephrolithotomy (PCNL). Balloon dilator is the most expensive method. Both of the incremental dilation techniques are more time consuming with higher failure rates. Hence, a prospective randomized study was conducted to compare the safety and efficacy of “single shot” dilation of the nephrostomy tract by amplatz dilator with serial alken metallic telescopic dilation technique in PCNL. Methods: Of the 138 renal stone patients who underwent PCNL from January 2015 to December 2015, 100 patients were randomized into two groups. Serial tract dilation with alken metallic dilators was used in group A (n=50), and one shot dilation technique in Group B (n=50). The access tract dilation time, success rate, blood loss and complications were evaluated. Results: Both the groups were comparable in terms of mean age, location and size (largest diameter) of the stone (p>0.05). No difference was observed in the procedural success rate between groups A and B (96% v 94% respectively, p=0.64). Mean access time was similar in both groups (5.89+2.67 vs 4.98+2.0 mins, p=0.06). Complications between the groups were not significantly different. There were 6 patients with previous open stone surgery in both the groups. Previous open stone surgery did not impact procedural success rate, access time and complications in both groups. Conclusion: One-shot dilation technique is equally as effective, safe and well tolerated as metal telescopic dilation techniques even in patients with history of ipsilateral open stone surgery.

ABSTRACT Background: Perioperative outcomes following surgery for brain tumors are an important indicator of the safety as well as efficacy of surgical intervention. Perioperative morbidity not only has implications on direct patient care, but also serves as an indicator of the quality of care provided, and enables objective documentation, for comparision in various clinical trials. We document our experience at a tertiary care referral, a dedicated neuro-oncology center in India. Materials and Methods: One hundred and ninety-six patients undergoing various surgeries for intra-axial brain tumors were analyzed. Routine microsurgical techniques and uniform antibiotic policy were used. Navigation/ intraoperative electrophysiological monitoring was not available. The endpoints assessed included immediate postoperative neurological status, neurological outcome at discharge, regional complications, systemic complications, overall morbidity, and mortality. Various risk factors assessed included clinico-epidemiological factors, tumor-related factors, and surgery-related factors. Univariate and multivariate analysis were performed. Results: Median age was 38 years. 72% had tumors larger than 4 cm. Neurological morbidity, and regional and systemic complications occurred in 16.8, 17.3, and 10.7%, respectively. Overall, major morbidity occurred in 18% and perioperative mortality rate was 3.6%. Although a few of the known risk factors were found to be significant on univariate analysis, none achieved significance on multivariate analysis. Conclusions: Our patients were younger and had larger tumors than are generally reported. Despite the unavailability of advanced intraoperative aids we could achieve acceptable levels of morbidity and mortality. Objective recording of perioperative events is crucial to document outcomes after surgery for brain tumors.

Abstract Background To explore the risk factors of extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-PE) infection through urine samples of hospitalized patients and establish a predictive model to improve treatment outcomes.MethodsThis retrospective study included all patients with an Enterobacteriaceae-positive urine sample at the first affiliated hospital of Jinan university from January 2018 to December 2019. Antimicrobial susceptibility patterns of ESBL-PE were analyzed, and multivariate analysis of related factors was performed. From these, a nomogram was established to predict the possibility of ESBL-PE infection. Simultaneously, susceptibility testing of a broad array of carbapenem antibiotics was performed on ESBL-PE cultures to explore possible alternative treatment options.ResultsOf the total 874 patients with urinary tract infections (UTIs), 272 (31.1%) were ESBL-PE positive. In the predictive analysis, five variables were identified as independent risk factors for ESBL-PE infection: male gender (OR=1.607, 95% CI 1.066-2.416), older age (OR=4.100, 95% CI 1.678-12.343), a hospital stay in preceding 3 months (OR=1.872, 95% CI 1.141-3.067), invasive urological procedure (OR=1.810, 95% CI 1.197-2.729), and antibiotic use within the previous 3 months (OR 0.546, 95% CI 0.314-0.948). In multivariate analysis, the data set was divided into a training set of 611 patients and a validation set of 263 patients The model developed to predict ESBL-PE infection was effective, with the AuROC of 0.650 (95% CI 0.577-0.725). Among the antibiotics tested, several showed very high effectiveness against ESBL-PE: amikacin (85.7%), carbapenems (83.8%), tigecycline (97.1%) and polymyxin (98.2%). ConclusionsThe nomogram is useful for estimating a bacteremic patient’s likelihood of infection with ESBL-PE. It could improve clinical decision making and enable more efficient empirical treatment. Empirical treatment may be informed by the results of the antibiotic susceptibility testing.

171 Background: The aims of this retrospective study were to analyze risk factors of lymph node metastasis undifferentiated-type early gastric cancer (UD-type EGC) and to select the suitable patient for endoscopic resection. Methods: We analyzed 368 patients who had undergone gastrectomy with lymphadenectomy for UD-type EGC between November 2001 and July 2016 at the Yeouido St. Mary’s Hospital. Using clinicopathological factors of patient age, size, an endoscopic macroscopic tumor form, ulceration, depth, histology, lymphatic involvement (LI) and venous involvement (VI), LNM risk was examined and stratified by univariate analysis and multivariate analysis. Results: Of the 368 patients, the lymph node metastases rate in patients with EGC was 48 patients (13%). 204 (55 %) had mucosal cancers and 164 (45 %) had submucosal cancers. Univariate analysis revealed > 60 age, > 2 cm, submucosal(sm), poorly cohesive carcinoma as significant prognostic factors. On multivariate analysis, > 60 age (odd ratio , 2.20; 95% confidence interval, 1.19~4.06), submucosal(odd ratio , 9.38; 95% confidence interval, 4.08~21.56), poorly cohesive carcinoma (odd ratio, 0.33; 95% confidence interval, 0.12~0.86) were independent risk factors for lymph node involvement. Conclusions: LNM-related factors in undiff-EGC were age, depth and pathology. We proposed that risk factors for metastases should be considered when choosing surgery for EGC.

383 Background: Venous thromboembolism (VTE) is a frequent complication of cancer or its treatment. Khorana (KRS) and Compass scores are two Risk Assessment Models for VTE. However, aUTC was not adequately represented and arterial events were not included, in these models. Methods: Data from pts with aUTC treated with at least one line of chemotherapy in our institution were analyzed. VaTE definition included: DVT and PE defined as venous events and peripheral arterial thrombosis or embolus, ischemic stroke and coronary events, grouped as arterial events. The association of baseline and treatment-related factors with the development of VaTE was assessed using competing-risk regressions. According to the results of our multivariate analysis we stratified patients according to the number of the identified risk factors. Results: 354 aUTC pts treated between 4/1995 and 9/2015 entered our study. 53% of pts had received cisplatin and 42% carboplatin-based regimens. 44 pts (12.4%) suffered 45 VaTEs (13 arterial, 32 venous) within a median time of 3.3 months. The cumulative and 6-month incidence was 14.8% (95% CI: 10.9-19.4) and 9.7% (95% CI: 6.8-13.1), [venous 10.5% (95% CI: 7.3-14.3)/7.5% (95% CI: 5-10.7); arterial 5.3% (95% CI: 2.8-9)/2.7% (95% CI: 1.3-5), respectively]. No association of the KRS and the COMPASS score with the incidence of VaTEs was observed. In the univariate and multivariate analysis, cumulative VaTE incidence was significantly increased in pts with “peripheral arterial disease (PAD) or history of VΤE” (adjusted SHR: 3.29; 95% CI: 1.65-6.55; p=0.001) and pts with other solid tumor (SHR: 2.20; 95% CI: 1.05-4.62; p=0.038). There was a strong correlation between the number of risk factors and the risk for VaTE development (p<0.001). Patients with 1 or 2, vs 0 factors had a 3-fold increased risk [cumulative incidence was 10.9% (95% CI: 7.4.-15.2) and 30.2% (95% CI: 18.4-42.8), respectively; SHR: 3.01 95% CI: 1.65-5.51]. Conclusions: Development of tumor-specific algorithms for the risk of vascular events is supported by our results. Pts with aUTC and a history of VTE, PAD and other solid tumor have a very high risk for VaTE. The role of prophylaxis should be prospectively studied.

Background and study aims: Long-term transmural double-pigtail stent (DPS) placement is recommended for patients with disconnected pancreatic duct syndrome (DPDS) and peripancreatic fluid collections (PFC). Long-term safety and efficacy of indwelling DPS were evaluated. Patients and methods: Medical files of patients treated with DPS for DPDS-associated PFC and a follow-up ≥48 months were reviewed. Early (<30 days) and late complications of DPS placement were evaluated and the primary endpoint –the incidence rate of late complications per 100 patients-years– was calculated. Short- and long term success rate of endoscopic treatment and PFC recurrence rate were among secondary endpoints. Results: From 2002 to 2014 we identified 116 patients [follow-up: 80.6 (34.4) months]. Among early complications (n=20), 6 occurred peri-interventionally. Late complications (n=17) were mainly pain due to DPS-induced ulcer or erosion (n=10) and 14 of these were treated conservatively or by stent removal. Two gastro-pancreatico-colo-cutaneous fistulas and one persisting bleed required surgical intervention. No DPS-related deaths were recorded. The incidence rate of late complications was 2.18 per 100 patient-years of follow-up; 95%CI [1.27, 3.49]. Short- and long-term success rate of endoscopic treatment was 97.4% [94.5, 100) and 94% [89.6, 98.3], respectively. The PFC recurrence rate was 28% [20.1, 35.9] and 92.3% of them occurred within the first two years. Stent migration, chronic pancreatitis and length of stent size (>6cm) were independently associated with higher rates of PFC recurrence. Conclusions: Long-term transmural drainage with DPS is a safe and effective treatment for DPDS-associated PFCs. However, about one fourth of PFC will recur.

AbstractClinically relevant postoperative pancreatic fistula (CR-POPF) is the considerable contributor to major complications after pancreatectomy. The purpose of this study was to evaluate the potential risk factor contributing to CR-POPF following distal pancreatectomy (DP) and discussed the risk factors of pancreatic fistula in order to interpret the clinical importance. All the patients who underwent DP in between January 2011 and January 2020 were reviewed retrospectively in accordance with relevant guidelines and regulations. The univariate and multivariate analysis was performed was performed to test an independent risk factors for pancreatic fistula. P<0.05 was considered statistically significant. In all of the 263 patients with DP, pancreatic fistula was the most common surgical complication 19.0%. The univariate analysis of 18 factors showed that the patients with a malignant tumor, soft pancreas, and patient without ligation of the main pancreatic duct are more likely to develop pancreatic fistula. However, on multivariate analysis the soft texture of the pancreas (OR= 2.381, P= 0.001) and the ligation of main pancreatic duct (OR= 0.388, P= 0.002) were only an independent influencing factor for CR-POPF. As a conclusion, pancreatic fistula was the most common surgical complication after DP, and the texture of pancreas and ligation of main pancreatic duct can influence an incidence of CR-POPF.

Abstract Purpose: The aim of this study was to evaluate the safety and efficacy of zero-fluoroscopy (ZF) catheter ablation (CA) for supraventricular tachycardias (SVT).Methods: 584 consecutive patients referred to our institution for CA of SVT were analysed. Patients were categorised into two groups; zero-fluoroscopy (ZF) group and conventional fluoroscopy (CF) group. The ZF group was further divided into two subgroups (adults and paediatric). Patient characteristics, procedural information, and follow-up data were compared. Results: The ZF group had a higher proportion of paediatric patients (42.2% vs 0.0 %; p < 0.001), resulting in a younger age (30.9 ± 20.3 years vs 52.7 ± 16.5 years; p < 0.001) and lower BMI (22.8 ± 5.7 kg/m2 vs 27.0 ± 5.4 kg/m2; p < 0.001). Procedure time was shorter in the ZF group (94.2 ± 50.4 min vs 104.0 ± 54.0 min; p = 0.002). There were no major complications and the rate of minor complications did not differ between groups (0.0% vs 0.4%; p = 0.304). Acute procedural success as well as the long-term success rate when only the index procedure was considered did not differ between groups (92.5% vs 95.4%; p = 0.155; 87.1% vs 89.2%; p = 0.422). When repeated procedures were included, the long-term success rate was higher in the ZF group (98.3% vs 93.5%; p = 0.004). The difference can be partially explained by the operators' preferences.Conclusion: The safety and efficacy of ZF procedures in adult and paediatric populations are comparable to that of CF procedures.

Background: Research shows that there is a high prevalence of suicide among nurses. Despite this, it has been 15 years since the last literature review on the subject was published. Aim: The aim of this article is to review the knowledge currently available on the risk of suicide among nurses and on contributory risk factors. Method: A search was conducted in electronic databases using keywords related to prevalence and risk factors of suicide among nurses. The abstracts were analyzed by reviewers according to selection criteria. Selected articles were submitted to a full-text review and their key elements were summarized. Results: Only nine articles were eligible for inclusion in this review. The results of this literature review highlight both the troubling high prevalence of suicide among nurses as well as the persistent lack of studies that examine this issue. Conclusion: Considering that the effects of several factors related to nurses' work and work settings are associated with high stress, distress, or psychiatric problems, we highlight the relevance of investigating work-related factors associated with nurses' risk of suicide. Several avenues for future studies are discussed as well as possible research methods.

There is new empirical evidence that the effects of impending death on cognition have been miscalculated because of neglect of the incidence of dropout and of practice gains during longitudinal studies. When these are taken into consideration, amounts and rates of cognitive declines preceding death and dropout are seen to be almost identical, and participants aged 49 to 93 years who neither dropout nor die show little or no decline during a 20-year longitudinal study. Practice effects are theoretically informative. Positive gains are greater for young and more intelligent participants and at all levels of intelligence and durations of practice; declines in scores of 10% or more between successive quadrennial test sessions are risk factors for mortality. Higher baseline intelligence test scores are also associated with reduced risk of mortality, even when demographics and socioeconomic advantage have been taken into consideration.
