One notable change to the 2018 United Network for Organ Sharing listing criteria was to allow for the use of noninvasive hemodynamic monitoring for inpatients listed as status 3 for heart transplantation. We wanted to explore the feasibility of performing daily focused echocardiograms in place of invasive monitoring in this population.

On retrospective chart review of inpatients listed for transplantation at our institution, 8 patients in the invasive monitoring group listed as status 1A (October 2016 to October 2018) and 9 patients in the echocardiographic group listed as status 3 (October 2018 to February 2020) were identified.

There were no significant differences between the 2 cohorts in the average measured/estimated right atrial, pulmonary artery systolic, and wedge pressures, although the echo cohort had lower cardiac index (P=.001). There were 2 patients with positive blood cultures treated with Swan exchange in Swan cohort and a total of 14 Swan exchanges. There were no infections in the noninvasive group.

We present our experience with the use of noninvasive daily hemodynamic assessment using focused echocardiograms to manage patients undergoing heart transplantation listing as status 3 under the new United Network for Organ Sharing allocation system. This approach appears safe and feasible; however, it requires validation in larger cohorts.

There is limited data regarding lung transplant (LT) outcomes among recipients of donors with a history of cocaine use. We sought to assess the burden of cocaine abuse among LT donors, describe their characteristics, and evaluate the association with post-transplant outcomes.

From the United Network for Organ Sharing database, we included adult patients (age ≥18 years) who underwent LT between 1996 and 2014 (N=20,106; mean age 53.7 ± 13 years; male 57%). Study groups were divided based on the donor history of recent cocaine abuse (last 6 months). Donor and recipient characteristics were compared between the 2 groups. With 1-year survival as the primary endpoint, multivariate logistic regression analysis was conducted to assess for an independent association with the donor history of cocaine use.

The overall frequency of donors with any history of cocaine use was 10.9% (n=2189), although less than half were current users (n=1001, 4.98%). Unadjusted 1-year survival was worse among recipients of donors wither criteria for organ quality.

Chronic thyroiditis (CT) is a common cause of thyroid dysfunction and could therefore adversely affect outcomes in patients undergoing heart transplant (HT). The incidence of post-HT CT and whether amiodarone, a commonly used anti-arrhythmic drug in patients with heart failure during pre-HT period, is associated with the development of post-HT CT are unknown.

A retrospective review of HT recipients from February 2, 2010 to October 16, 2018 was performed. Patients who lacked relevant pre-/post-HT records, underwent thyroidectomy, had pre-HT thyroid dysfunction or thyroiditis within 15 days post-HT, and those on amiodarone during the post-HT period were excluded, yielding a final cohort of 75 patients.

Patients had a mean age of 63.3 ± 1.4 years and were predominantly male (90.7%) and white (80%). The incidence of post-HT CT was 32% with the majority (83.3%) manifesting as hypothyroidism. Median time to diagnosis of CT after transplant was 10.2 months (interquartile range, 4-27.4). Additionally, the CT group had higher pre-HT use of amiodarone (non-CT vs CT 21.6% vs 50%, P=.01), higher prevalence of atrial fibrillation (non-CT vs CT 23.5% vs 45.8%; P=.05), and more stage IV/V chronic kidney disease (non-CT vs CT 2% vs 16.7%, P=.02). On multivariate analysis, pre-HT amiodarone use was associated with the development of post-HT CT after adjustment for age, sex, and chronic kidney disease (odds ratio, 3.65; 95% CI, 1.17-11.44; P=.03).

The incidence of post-HT CT is high and is strongly associated with pre-HT amiodarone use underpinning the importance of closely following the post-HT thyroid profile in these patients.

Attributes of vancomycin nephrotoxicity (VN) are well documented, including its clinical manifestations and renal morphologic changes. However, VN has not been emphasized as the cause of acute kidney injury (AKI) in the renal transplant setting. We report the first 3 such cases. In each of these cases, AKI developed concurrently with vancomycin treatment and resolved after its cessation. As compared with the general population, VN in the renal transplant setting displayed some unusual clinical behaviors. Its development was rather capricious, being noted in some but not every episode of vancomycin treatment, even in the same individual. AKI developed gradually in conjunction with protracted vancomycin treatment, in contrast to a precipitous course in the nontransplant setting. However, renal transplant biopsies showed typical features of VN in each case. VN is an unusual but now well-documented cause of AKI in renal transplant recipients. VN in this setting may display some atypical features, setting it apart from that in the general population. However, renal transplant biopsy changes are characteristic and are amenable to a definitive diagnosis.

Renal transplantation is the gold standard treatment for end-stage renal disease, however, in 20% of cases, the graft develops a delayed graft function (DGF) that is associated with both early and late worsening of the outcome. The aim of this study was to examine and validate in a population of transplanted patients the appropriateness of the predictive score systems of DGF available to identify patients who might take advantage of a tailored immunosuppressive therapy.

We conducted a systematic review of the literature to identify articles concerning scoring systems predicting DGF to identify those applicable to the study population and subsequently comparing their appropriateness for defining the most accurate one.

From an analysis of the scientific literature, we found 7 scoring systems predicting DGF. Of these, 3 can be calculated for the study population. We enrolled 247 renal transplants in the study. DGF was recorded in 41 cases (15.95%). The Irish score recognized 25 of 41 cases (60.98%), the Jeldres score 41 of 41 cases (100%), and the Chapal score only 7 of 41 (17.07%). Although the Irish score did not identify all cases of DGF, the analysis of data revealed that it is the most accurate, with area under the receiver operating characteristic almost overlapping.

The study resulted in some interesting and promising conclusions about the predictability of DGF, defining the Irish score as the most reliable. This result can be considered the fundamental requirement to develop a custom therapeutic algorithm to be applied to all recipients with higher probability of developing DGF.

The medium-term effect of an implant-retained mandibular overdenture on bone remodeling in the maxilla and posterior mandible of edentulous patients and the effects on quality of life have not been established.

The purpose of this prospective observational clinical study was to evaluate the 3-year effects of implant-retained mandibular overdentures on oral-health-related quality of life (OHRQoL) and bone remodeling in different regions of the maxilla and mandible in participants with atrophic or nonatrophic mandibles.

Twenty-six edentulous participants received 2 narrow-diameter implants in the anterior mandible. Mandibular bone atrophy was categorized from presurgical panoramic radiographs according to the Cawood and Howell criteria. OHRQoL was assessed by using the OHIP-EDENT questionnaire. Participants were evaluated annually for 3 years to measure the marginal bone loss and bone area of the posterior mandible, and the anterior and posterior regions of the maxilla were assessed annually through panorars of follow-up.Marginal bone loss around immediately placed implants may compromise esthetic outcomes in the anterior maxilla. The relatively recent socket-shield technique of partial extraction therapy has been described as being useful to maintain the structure of peri-implant tissues. The present technique report introduced a digital workflow to perform image-guided implant placement after partial extraction therapy. In this technique, digital 3-dimensional images are used to plan and orient the flapless surgical procedure and to digitally design a custom abutment based on the natural emergence profile as segmented from the tooth to be extracted.

This study aimed to determine the optimal intervention modality for malignant GOO by comparing clinical outcomes after Gastrojejunostomy and endoscopic stenting.

Two authors independently searched Web of Science, PubMed, Embase, and the Cochrane Library for articles before February 2021 to compare the clinical outcomes of GOO patients undergoing GJ or ES.

This meta-analysis included 31 articles with 2444 GOO patients. Although the GJ group outperformed the ES group in technical success (OR,3.79; P=0.003), clinical success was not significantly different between the two groups (OR,1.25; P=0.50). The GJ group had a longer hospitalization, lower re-obstruction and lower reintervention. Moreover, GJ had a better survival than ES in the gastric cancer group (HR, 0.33; P=0.009). However, no significant statistical difference was observed in the pancreatic cancer group (HR, 0.55; P=0.159).

Both GJ and ES are safe and effective intervention modalities for malignant GOO. GJ had significantly improved survival in gastric cancer patients with GOO, while no significant difference was observed between the two groups in pancreatic cancer patients with GOO.

Health literacy is a determinant of health. Few studies characterize its association with surgical outcomes.

Retrospective cohort study of patients undergoing elective colorectal surgery 2015-2020. Health literacy assessed using Brief Health Literacy Screening Tool. Outcomes were postoperative complications, LOS, readmissions, mortality.

Of 552 patients, 46 (8.3%) had limited health literacy, 506 (91.7%) non-limited. Median age 57.7 years, 305 (55.1%) patients were female, 148 (26.8%) were Black. Limited patients had higher rates of overall complications (43.5% vs. 24.3%, p=0.004), especially surgical site infections (21.7% vs. 11.3%, p=0.04). Limited patients had longer LOS (5 vs 3.5 days, p=0.006). Readmissions and mortality did not differ. On multivariable analysis, limited health literacy was independently associated with increased risk of complications (OR 2.03, p=0.046), not LOS (IRR 1.05, p=0.67).

Limited health literacy is associated with increased likelihood of complications after colorectal surgery.
