Question: Context: Some living kidney donors report lost income during recovery from surgery. Little is known about whether concern for living donor's lost income affects the decision to undergo donation evaluation and the willingness of transplant candidates to discuss living kidney donation (LKD) with others.", 'To examine whether transplant patients were told by potential donors about lost income concerns and whether patients chose not to discuss LKD with others due to lost income concerns.', "Kidney transplant patients (185 wait-listed candidates, 171 deceased donor recipients, and 100 live donor recipients) at 2 centers completed a questionnaire to assess whether concern about donor's lost income was a consideration in discussion about LKD with others.", 'One-third (32%) were told by a family member/friend that they were willing to donate but were concerned about potential lost income. The majority of those who expressed financial concern (64%) did not initiate donation evaluation. Many patients (42%) chose not to discuss living donation with a family member/friend due to concern about the impact of lost income on the donor. In the multivariable model, lower annual household income was the only statistically significant predictor of both having a potential donor expressing lost income concern and choosing not to talk to someone because of lost income concern.
Answer: Findings from the current study underscore how concern about income loss for living donors may affect decision-making by both transplant candidates and potential donors.

Answer: Does concern for Lost Income Following Donation deter Some Patients From Talking to Potential Living Donors?

Question: Context: Progenitor cells isolated from cardiac explant-derived cells improve cardiac function after myocardial infarction (MI). To fully realize the therapeutic potential of these cells, it is essential to develop a safe and efficient delivery method. Therefore, the objective of this study was to determine the efficacy of our newly developed approach to retrograde coronary vein (RCV) infusion of cardiac c-Kit(+) cells in a small-animal model of congestive heart failure (CHF).', 'Sprague-Dawley rats underwent experimental MI. After 21 days, cardiac explant-derived c-Kit(+) cells were delivered to both sham and CHF animals using RCV delivery. Vehicle-treated (serum-free medium) sham and CHF animals were used as controls. Cardiac function and heart tissues were evaluated 21 days post-transplantation.', 'RCV-delivered cells were retained in infarcted hearts for at least 21 days after transplantation. At 21 days post-RCV infusion, the majority of transplanted c-Kit(+)/GFP(+) cells were localized in the left ventricle. Compared with vehicle-treated CHF animals, RCV-treated rats showed a significant improvement in cardiac function. Furthermore, RCV-treated rats exhibited an increase in capillary density, a decrease in total heart collagen, and a reduction in both infarct size and cardiomyocyte hypertrophy when compared with vehicle-treated CHF rats.
Answer: Our study showed that the RCV infusion approach is an efficient technique for targeted cell delivery to the infarcted myocardium. Cardiac c-Kit(+) cells, delivered using RCV infusion ameliorated progression of heart failure, improved cardiac function and retarded myocardial remodeling in heart failure rats.

Answer: Does retrograde coronary vein infusion of cardiac explant-derived c-Kit+ cells improves function in ischemic heart failure?

Question: Context: The aim of this study was to evaluate whether percutaneous transhepatic biliary drainage (PTBD) increases the incidence of seeding metastasis and shortens postoperative survival compared with endoscopic biliary drainage (EBD).', 'A total of 376 patients with distal cholangiocarcinoma who underwent pancreatoduodenectomy following either PTBD (n=189) or EBD (n=187) at 30 hospitals between 2001 and 2010 were retrospectively reviewed. Seeding metastasis was defined as peritoneal/pleural dissemination and PTBD sinus tract recurrence. Univariate and multivariate analyses followed by propensity score matching analysis were performed to adjust the data for the baseline characteristics between the two groups.', 'The overall survival of the PTBD group was significantly shorter than that of the EBD group (34.2% vs 48.8% at 5years; P=0.003); multivariate analysis showed that the type of biliary drainage was an independent predictor of survival (P=0.036) and seeding metastasis (P=0.001). After two new cohorts with 82 patients each has been generated after 1:1 propensity score matching, the overall survival rate in the PTBD group was significantly less than that in the EBD group (34.7% vs 52.5% at 5years, P=0.017). The estimated recurrence rate of seeding metastasis was significantly higher in the PTBD group than in the EBD group (30.7% vs 10.7% at 5years, P=0.006), whereas the recurrence rates at other sites were similar between the two groups (P=0.579).
Answer: Compared with EBD, PTBD increases the incidence of seeding metastasis after resection for distal cholangiocarcinoma and shortens postoperative survival.

Answer:
Is percutaneous biliary drainage oncologically inferior to endoscopic drainage : a propensity score matching analysis in resectable distal cholangiocarcinoma?
