Therefore, these findings suggest that knockout of E2F1 could affect ADSCs to inhibit the survival of fat grafts by downregulating PPAR-γ expression.Background Urinary tract infection (UTI) occurs in 21% of kidney recipients within the first 3 months after transplantation (KTx). It is associated with impaired graft function. Ureteral stent placement increases the occurrence of UTIs. The aim of this study was to assess the correlation between double-J placement, UTI incidence, and graft function. Material and methods We conducted an observational study in 753 patients transplanted between 2010 and 2017 in compliance with the Helsinki Congress and the Istanbul Declaration. Recipients with preserved graft function at the 1-year follow-up were included. Medical records were searched for intraoperative double-J placement, UTI incidence, and estimated glomerular filtration rate (eGFR) on the 30th and 360th days post-transplant. Pretransplant hypothetical estimated GFR (heGFR) of each donor was calculated from donors' age and physiological age-dependent loss of functional nephrons. Spearman's correlation and linear regression analyses were applied. P less then .05 was considered significant. Results UTIs occurred in 239 (31.8%) patients. On the 30th day after KTx, eGFR was significantly lower in the UTI group (median, 39.5 vs 43.2; P less then .01). A similar pattern was seen 1 year after KTx (47.5 vs 54.2; P less then .01). Urinary stents were placed in 213 (28.3%) patients. UTIs occurred in 92 (43.2%) of them and in 147 (27.2%) of nonstented patients (odds ratio 2; 95% confidence interval [CI], 1.5-2.8; P less then .01). Median donor heGFR was 105.8 mL/min/1.73 m2, whereas median donor Modification of Diet in Renal Disease (MDRD) GFR was 64.2 mL/min/1.73 m2. A moderate correlation between age-adjusted heGFR and 1-year transplant function (r = .47) was noted. Conclusions UTIs in the early post-transplant period decreased 1-year eGFR by 4 to 5 mL/min/1.73 m2. UTIs occurred twice as often when a urinary stent was placed.Background Lung transplant (LTx) is a procedure associated with risk of complications related to airway stenosis that can be treated with bronchoscopic interventions (BIs). The aim of the study was to assess the frequency and risk factors associated with increased need of bronchial interventions in the post-transplant period. Methods The retrospective study reviewed cases of 165 patients (63 women) who underwent LTx from April 2013 to June 2019. For dichotomous discrete variables (occurrence or lack of intervention) multivariate logistic regression analysis was performed to assess the aforementioned risk factors. Results BIs were required among 38.55% of lung recipients (n = 65). The number of interventions/patient/y decreases between years 1 and 2 (P less then .001), 2 and 3 (P = .013), and 3 and 4 (P less then .001); after the fourth year post LTx the differences are not statistically significant. Each 1 mm Hg above 25 mm Hg of mean pulmonary arterial pressure causes statistically significant elevation in the number of interventions by 0.7% in the first year after the procedure. The number of BIs per patient among lung recipients who received a transplant because of idiopathic pulmonary arterial hypertension was statistically significantly higher compared with patients with another underlying lung disease. Conclusions Airway complications developed in the post-transplant period caused a significant number of patients to be in need of BI, especially balloon bronchoplasty. The highest number of interventions occurred within the first year after LTx, and BI decreases over time. Mean pulmonary arterial pressure measured during qualification may have the ability to predict whether the patient would require BI after LTx.Background Nearly all publications related to endoscopic treatment of biliary anastomotic stricture after liver transplant have reported cases that can be cannulated. However, very few publications discuss endoscopic treatment of biliary anastomotic stricture (BAS) in which the guide wire does not pass through the stricture site. The purpose of this article is to analyze the long-term outcome of the Rendezvous technique in severe strictures through which guide wires cannot cannulate. Methods Between 2010 and 2017, a total of 29 patients who underwent Rendezvous technique because of severe BAS after liver transplant were included in the study. Results Twenty-nine patients who underwent the Rendezvous technique showed a 100% technical success rate. Ten patients (34.4%) required stent removal; the mean stenting period was 14.9 (SD, 5.6) months (range, 6.65-24.14 months). A total of 19 patients were maintained without stent removal; the stent-maintaining period was 13.1 (SD, 8.4) months (range, 3.48-38.61 months). Two patients receiving left lobe grafts maintained the stents for 27.1 (SD, 16.2) months. In left lobe graft, the duct anastomosis position moves to the right posteroinferior side of the patient. Conclusions Our results suggest that the stenting period of the Rendezvous technique was longer in severe BAS than in cannulated endoscopic retrograde cholangiopancreatography cases. Especially in the left liver, the position of the duct anastomosis changed to the right posteroinferior of the patient. click here Thus, the donor duct and the recipient duct are angulated, kinking worsens, and the stenting period becomes longer.It is well known that correction of uremia by kidney transplantation alone (KTA) improves left ventricular systolic dysfunction (LVSD). However, for kidney transplant candidates with extremely severe LVSD, KTA is considered to be contraindicated because of the high risk of peri-operative management. We report a case of successful kidney transplantation with severe LVSD with an ejection fraction (EF) of 14% and low systolic blood pressure (SBP) of approximately 65 to 80 mm Hg. In this case, in spite of an extremely low EF and SBP, functional capacity was assessed using metabolic equivalents (METs) and showed a level of almost 4. The operation was performed carefully, considering the cardiac, operative, and anesthetic risks. No surgical complications occurred, and the patient received intensive care during the peri-operative period. His postoperative course was almost favorable, and he was discharged on postoperative day 29. The present report concludes that evaluation of METs may expand the indication for KTA in patients with extremely severe LVSD.
