Background: Community-acquired UTI is the most common bacterial infection managed in general medical practice that can lead to life-threatening outcomes. While UTIs are primarily caused by colonizing the patient's gut, it is unclear whether the gut resident profiles can predict the person's risks for UTI and optimal antimicrobial treatments. Thus, we conducted an eighteen-month long community-based observational study of fecal colonization and UTI in women aged 50 years and above.

The use of routine monitoring of donor-derived cell-free DNA (dd-cfDNA) after kidney transplant may allow clinicians to identify subclinical allograft injury and intervene prior to development of clinically evident graft injury. To evaluate this, data from 1092 kidney transplant recipients monitored for dd-cfDNA over a three-year period was analyzed to assess the association of dd-cfDNA with histologic evidence of allograft rejection. Elevation of dd-cfDNA (0.

The age of COVID-19 calls for a different approach toward global well-being and flourishing through the transcendence suffering as advocated by existential positive psychology. In the present study, we primarily explained what self-transcendence is and why it represents the most promising path for human beings to flourish through the transformation of suffering in a difficult and uncertain world. After reviewing the literature on self-transcendence experiences, we concluded that the model of self-transcendence presented by Frankl is able to integrate both of the characteristics associated with self-transcendence.

We report that there is a recent global expansion of numerous independent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants with mutation L452R in the receptor-binding domain (RBD) of the spike protein. The massive emergence of L452R variants was first linked to lineage B.1.

The recent rise in mutational variants of SARS-CoV-2, especially with changes in the Spike protein, is of significant concern due to the potential ability for these mutations to increase viral infectivity, virulence and/or ability to escape protective antibodies. Here, we investigated genetic variations in a 414-583 amino acid region of the Spike protein, partially encompassing the ACE2 receptor-binding domain (RBD), across a subset of 570 nasopharyngeal samples isolated between April 2020 and February 2021, from Washington, California, Arizona, Colorado, Minnesota and Illinois. We found that samples isolated since November have an increased number of amino acid mutations in the region, with L452R being the dominant mutation.

Recurrent toxic shock syndrome (TSS) is uncommon. A certain level of clinical suspicion is indicated with a complex sepsis presentation in the postoperative kidney transplant patient. We present a case of presumed recurrent postoperative TSS in a living kidney transplant recipient.

Background: Studies have shown significant improvement in hepatocellular carcinoma (HCC) recurrence rates after liver transplantation since the united network of organ sharing (UNOS) implementation of a 6-month wait period prior to accrued exception model for end-stage liver disease (MELD) points enacted on October 8, 2015. However, few have examined the impact on HCC dropout rates for patients awaiting liver transplant. Our objective is to evaluate the outcomes of HCC dropout rates before and after the mandatory 6-month wait policy enacted.

Background: Postoperative hemorrhage has been described at rates of 14% in kidney transplant (KT) literature. The preferred management of postoperative hemorrhage in this population is not well described. We hypothesized a difference in outcomes with operative versus nonoperative management of hemorrhage after kidney transplantation.

Incisional hernias occur after abdominal organ transplantation with rates of 1.6 per cent to 18 per cent in kidney transplants (KTs) and 1.7 to 32.

The United Network for Organ Sharing (UNOS) implemented a policy that requires patients with hepatocellular carcinoma seeking liver transplantation to wait six months before being granted Model for End-Stage Liver Disease exception points. We investigated the difference in resource utilization between patients who underwent liver transplantation before and after the present policy. We conducted a retrospective cohort study of adult liver transplants from 2013 to 2018.

Background: The use of autologous arteriovenous fistulae (AVF) for hemodialysis (HD) is the gold standard; however, for many patients at tertiary referral centers, this is not an option.

Methods: We conducted a four year retrospective cohort study to evaluate HD access outcomes with AVF, bovine carotid artery (BCA), and polytetrafluoroethylene arteriovenous graft (PTFE).

Results: The study contained 416 AVF, 175 BCA, and 58 PTFE, N = 649.

The demand for organs for kidney transplantation (KTX) compels the use of high-risk donation after circulatory death donors (DCDs) and extended criteria donors (ECDs). Many deceased donors receive prehospital CPR, but the literature does not address CPR as a benefit to graft survival. We hypothesized that donor prehospital CPR correlates with improved graft survival with high-risk DCD/ECD kidneys.

Background: We seek to present our experience with innovative abdominal wall arteriovenous access grafts for patients who have run out of traditional dialysis access options.

Methods: We retrospectively reviewed our cohort of patients who have undergone creation of abdominal wall grafts. In all patients, an iliac artery was used for inflow and either an iliac vein or the distal inferior vena cava (IVC) was use for the outflow.

Although the adverse allograft outcomes associated with HLA antibodies are well documented, some controversy exists regarding the importance of low-level donor specific anti-HLA antibodies (DSA). To provide further detail on this controversy, we prospectively looked at low-level DSA in negative T- and B-cell flow cytometric crossmatch (FCXM) or acceptable reactive crossmatch (ARC) patients who each underwent protocol based post-transplant antibody monitoring. HLA Class I and II antibody screening and specificity determination was conducted via a solid phase assay (SPA) and FCXM versus donor and autologous T and B cells.

Background: The residents of Puerto Rico (PR) had limited access to liver transplantation (LTx) prior to 1996. LTx remains locally unavailable and success rates for LTx for patients from PR have never been published. The outcome of the first 100 LTx recipients from PR transplanted at our center is analyzed.

Objective: To report our contemporary experience with renal autotransplantation (AT), an established treatment for managing patients with a shortened ureter or renovascular disease, as despite its historical importance, AT remains an underused technique by urologists.

Patients And Methods: All patients undergoing AT between 1997 and 2002 for a short ureter after ureteric injury and for renovascular disease were assessed by creatinine level and blood pressure before and after surgery, and antihypertensive drug use and complications.

Results: Eleven patients had AT for renovascular disease and four for ureteric injury.

Background: Cryopreserved cadaveric venous or arterial allografts are used in ESRD patients as an alternative to synthetic grafts for hemodialysis access. We evaluated the effect of these allografts on the PRA against HLA class I and II antigens in 11 ESRD patients awaiting a kidney transplant.

Methods: Flow Cytometry using purified antigen coated beads (Flow PRA Beads) was used to determine PRA against HLA class I and II antigens.

LifeLink Foundation, a not-for-profit organization, has been the driving force and absolutely essential entity for kidney and liver transplantation in Tampa providing all the components (patient, organs and clinicians) save for inpatient hospitalization. It also plays a big role in the heart transplant program.

Background: A novel but controversial method to increase the utilization of aged donor kidneys is the transplantation of both kidneys as a dual transplant. Initial single-center reports demonstrated outcomes similar to single kidneys from younger donors. In this report, we compare outcome in recipients of kidneys from donors > or =54 years of age who received a single kidney transplant reported to the United Network for Organ Sharing Scientific Registry versus a dual kidney transplant reported to the Dual Kidney Registry.

Substantial quantities of interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF-alpha) are produced within the pancreatic parenchyma during acute pancreatitis. Recent evidence suggests that IL-1 beta and TNF-alpha propagate acute pancreatitis and intensify the resulting pancreatic acinar cell death. This study examines the direct effect of IL-1 beta and TNF-alpha on pancreatic acinar cells.
