How to increase first-time donors' returns? The postdonation letter's content can make a difference.

BACKGROUND: Retention of first-time donors is pivotal for blood collection centers. The present study built on research showing the importance of donor identity among regular donors and sought to compare the effectiveness of various communication strategies on return rate. STUDY DESIGN AND METHODS: Postal letters were sent to a large sample of first-time whole blood donors (N = 1219) a few weeks following their first donation. Four versions of this letter were differently constructed in a way to boost the acquisition of donor identity (i.e., by including information about their ABO and Rh(D) blood group, emphasizing the salience of donor identity, offering a keyring with personalized information, or specifying the percentage of those sharing the same ABO and Rh(D) blood group). One version with no identity-related information served as a control condition. Participants' subsequent blood donations were tracked for 5-22 months after receiving the letter. RESULTS: Survival analysis showed that the return rate was significantly higher among those who had received information about the percentage of the country's population with the same ABO and Rh(D) blood group (in comparison with the four other versions). There was no significant effect on the blood type rarity. CONCLUSION: Blood collection centers could orient the strategy employed to communicate with first-time donors to improve donors' retention. Arousing a sense of social identification with others with the same blood type may reveal a promising avenue.

Intra-pancreatic distal cholangiocarcinoma and pancreatic ductal adenocarcinoma: a common short and long-term prognosis?

The aim of the study was to compare histological features, postoperative outcomes, and long-term prognostic factors after pancreaticoduodenectomy for distal cholangiocarcinoma and pancreatic ductal adenocarcinoma. From 2005 to 2017, 188 pancreaticoduodenectomies (pancreatic ductal adenocarcinoma n = 151, distal cholangiocarcinoma n = 37) were included. Postoperative outcomes were compared after matching on pancreatic gland texture and main pancreatic duct size. Matching according to tumor size, lymph node invasion and resection margin was used to compare overall and disease-free survival. Distal cholangiocarcinoma patients had more often "soft" pancreatic gland (P = 0.002) and small size main pancreatic duct (P = 0.001). Pancreatic ductal adenocarcinoma patients had larger tumors (P = 0.009), and higher lymph node ratio (P = 0.017). Severe morbidity (P = 0.023) and clinically relevant pancreatic fistula (P = 0.018) were higher in distal cholangiocarcinoma patients. After matching on gland texture and main pancreatic duct diameter, clinically relevant postoperative pancreatic fistula was still more frequent in distal cholangiocarcinoma patients (P = 0.007). Tumor size > 20 mm was predictive of impaired overall survival (P = 0.024) and disease-free survival (P = 0.003), tumor differentiation (P = 0.027) was predictive of impaired overall survival. Survival outcomes for distal cholangiocarcinoma and pancreatic ductal cholangiocarcinoma were similar after matching patients according to tumor size, lymph node invasion and resection margin. Long-term outcomes after pancreaticoduodenectomy for distal cholangiocarcinoma and pancreatic ductal adenocarcinoma patients are similar. Postoperative course is more complicated after pancreaticoduodenectomy for distal cholangiocarcinoma than pancreatic ductal adenocarcinoma. After pancreaticoduodenectomy, patients with distal cholangiocarcinoma and pancreatic ductal adenocarcinoma have similar long-term oncological outcomes.

Seasonal variations in cardiac implantable electronic device infections.

Infections of cardiac implantable electronic devices (CIEDs) have increased over the past decade. However, the impact of the climate on CIED infections is unknown. To determine whether there is a seasonal variation in CIED infections. In this single-center observational study, retrospective analysis of prospectively collected data was performed. Timone Hospital in Marseille (south-east France) is a tertiary care institution and the regional reference center for management of CIED infections. All consecutive patients with CIED extractions for infectious reasons were included over a 12-year period. We noted the mean temperature (°C), precipitation (mm) and the incidence of CIED infections over this period. Among 612 patients [mean (standard deviation) age, 72.4 (13.0) years; 74.0% male], 238 had endocarditis alone (38.9%), 249 had pocket infection alone (40.7%), and 125 had both (20.4%). We found bacterial documentation in 428 patients (70.0%), commensal in 245 (40.0%). The incidence of CIED infections was positively associated with high temperature (regression coefficient = 0.075; P = 0.01) and precipitation (regression coefficient = 0.022; P < 0.01). Seasonal variation was specific of pocket infections, whether they were associated with endocarditis or not. Subgroups with infection seasonality were: women, elderly people (> 75 years), late CIED infection and skin commensal bacterial infections. We found a seasonal variation in pocket infections, whether associated with endocarditis or not. Infections were associated with elevated temperatures and precipitation. Therefore, specific prevention strategy should be discussed in high-risk patients.

C-Reactive Protein on Postoperative Day 1 Is a Reliable Predictor of Pancreas-Specific Complications After Pancreaticoduodenectomy.

BACKGROUND: Postoperative pancreatic fistula and pancreas-specific complications have a significant influence on patient management and outcomes after pancreatoduodenectomy. The aim of the study was to assess the value of serum C-reactive protein on the postoperative day 1 as early predictor of pancreatic fistula and pancreas-specific complications. METHODS: Between 2013 and 2016, 110 patients underwent pancreaticoduodenectomy. Clinical, biological, intraoperative, and pathological characteristics were prospectively recorded. Pancreatic fistula was graded according to the International Study Group on Pancreatic Fistula classification. A composite endpoint was defined as pancreas-specific complications including pancreatic fistula, intra-abdominal abscess, postoperative hemorrhage, and bile leak. The diagnostic accuracy of serum C-reactive protein on postoperative day 1 in predicting adverse postoperative outcomes was assessed by ROC curve analysis. RESULTS: Six patients (5%) died and 87 (79%) experienced postoperative complications (pancreatic-specific complications: n = 58 (53%); pancreatic fistula: n = 48 (44%)). A soft pancreatic gland texture, a main pancreatic duct diameter < 3 mm and serum C-reactive protein ≥ 100 mg/L on postoperative day 1 were independent predictors of pancreas-specific complications (p < 0.01) and pancreatic fistula (p < 0.01). ROC analysis showed that serum C-reactive protein ≥ 100 mg/L on postoperative day 1 was a significant predictor of pancreatic fistula (AUC: 0.70; 95%CI: 0.60-0.79, p < 0.01) and pancreas-specific complications (AUC: 0.72; 95%CI: 0.62-0.82, p < 0.01). ROC analysis showed that serum C-reactive protein ≥ 50 mg/L at discharge was a significant predictor of 90-day hospital readmission (AUC: 0.70; 95%CI: 0.60-0.79, p < 0.01). CONCLUSIONS: C-reactive protein levels reliably predict risks of pancreatic fistula, pancreas-specific complications, and hospital readmission, and should be inserted in risk-stratified management algorithms after pancreaticoduodenectomy.

Comparison of epicardial vs. endocardial reimplantation in pacemaker-dependent patients with device infection.

Aims: Reimplantation of cardiac implantable electronic devices (CIEDs) after extraction due to device infection is a major issue in pacemaker-dependent patients. We compared in-hospital and long-term outcomes with two techniques: epicardial reimplantation (EPI) before CIED extraction and temporary pacing (TP) with a view to delayed endocardial reimplantation. Methods and results: Two cohorts of consecutive pacemaker-dependent patients who underwent transvenous lead extraction at our tertiary centre were included in this retrospective cohort study. According to successive policies, either the EPI or the TP approach was used. In-hospital complications occurred at similar rates in the EPI (n = 59) and TP (n = 52) cohorts (37.3% vs. 32.7%, respectively; P = 0.61). Thirteen (25.0%) patients in the TP cohort eventually were reimplanted epicardially, mainly because of infection of the temporary lead. Finally, 65 patients were discharged with an epicardial device and 37 with an endocardial device. Median follow-up was 41.7 (interquartile range 34.1-51.5) months. No difference was observed in long-term mortality according to the reimplantation strategy, but use of TP was associated with a reduced risk of late endocarditis and device reintervention (hazard ratio (HR) 0.25, 95% confidence interval (CI) 0.09-0.069, P = 0.01), whereas epicardial device reimplantation was associated with an increased risk (HR 3.62, 95% CI 1.07-12.21, P = 0.04). Conclusion: We observed similar in-hospital outcomes in our EPI and TP cohorts. Twenty-five percent of the patients initially paced by a TP strategy finally needed an epicardial device, mainly because of infection of their TP lead. Use of TP resulted in lower rates of late endocarditis and device reintervention.

Venous Resection in Pancreatic Ductal Adenocarcinoma: Impact of Surgical Experience on Early Postoperative Courses.

BACKGROUND/AIM: The aim of this study was to determine the effects of surgical experience on early postoperative courses after pancreaticoduodenectomy (PD) with venous resection. PATIENTS AND METHODS: From 2005 to 2014, 134 patients were analyzed, 62 and 72 patients were resected in periods 1 (2005-2009) and 2 (2010-2014) respectively; 115 and 19 patients underwent PD with venous resection in high- and low-volume center groups respectively. RESULTS: Of the entire cohort, mortality rate was 4%. There were no significant differences between the two periods. In the low-volume center group, the mortality rate was increased (21% vs. 2%, p<0.01) and the mean length of hospital stay was longer (25 (±27) days vs. 17 (±8) days, p=0.04). The high-volume center group was the only independent protective factor regarding death (OR=0.04, 95%CI (0.01-0.38), p<0.01) and length of hospital stay (OR<0.01, 95%CI (0.00-0.43), p=0.03). CONCLUSION: Patients who present isolated venous invasion must be referred to high-volume centers for surgery.
