This study aimed to investigate the effects of documentation status on pediatric kidney transplant outcomes in a single-center setting, emphasizing the significance of state insurance access for undocumented patients and federal policies like Deferred Action for Childhood Arrivals (DACA) on patient outcomes. A cohort of 283 patients, including 48 undocumented individuals, who received their first kidney transplant as children between 1998 and 2011 was analyzed. There was no significant difference in unadjusted all-cause (P = .

Article Synopsis
  • Donation after circulatory death (DCD) liver transplantation (LT) has a low occurrence in the U.S. but may provide reasonable outcomes for patients with high liver disease severity (MELD≥35).
  • Analysis from UCSF and UNOS cohorts showed similar five-year survival rates between DCD and brain death donor (DBD) liver transplants, though DCD recipients experienced more complications like biliary issues and longer hospital stays.
  • Factors such as younger donor age and recent transplant years improved survival rates; however, DCD grafts were identified as a risk factor in one cohort, indicating the need for careful candidate selection.

Purpose: To evaluate the diagnostic accuracy of the 131I-6β-iodomethyl-19-norcholesterol (NP-59) adrenal scintigraphy for the subtyping diagnosis of primary aldosteronism (PA), considering as gold standard for the diagnosis of unilateral PA (UPA), either the results of the adrenal venous sampling (AVS) or the outcome after adrenalectomy.

Methods: A retrospective multicenter study was performed on PA patients from 14 Spanish tertiary hospitals who underwent NP-59 scintigraphy with an available subtyping diagnosis. Patients were classified as UPA if biochemical cure was achieved after adrenalectomy or/and if an AVS lateralization index > 4 with ACTH stimulation or >2 without ACTH stimulation was observed.

Article Synopsis
  • Long-term success of beta-cell replacement is hindered by the toxic effects of calcineurin inhibitors (CNI) on beta-cells and kidney function.
  • A study was conducted on 10 Type 1 diabetes patients who received islet transplants with either belatacept or efalizumab for immunosuppression, with 70% of them remaining insulin-independent after 10 years.
  • Although patients generally maintained their kidney function, those undergoing pancreas-after-islet (PAI) transplants experienced more significant renal impairment due to CNI, and repeat islet transplants did not effectively sustain long-term insulin independence.

Unlabelled: Although steroid avoidance (SA) has been studied in deceased donor liver transplant, little is known about SA in living donor liver transplant (LDLT). We report the characteristics and outcomes, including the incidence of early acute rejection (AR) and complications of steroid use, in 2 cohorts of LDLT recipients.

Methods: Routine steroid maintenance (SM) after LDLT was stopped in December 2017.

Background: Malignant peritoneal mesothelioma (MPM) is a rare malignancy with a historically poor prognosis. Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has emerged as an effective therapy for patients with peritoneal malignancies. A contemporary analysis of trends in management of and survival from MPM is warranted.

Introduction: The COVID-19 pandemic is a global public health problem. Patients with end-stage renal disease on hemodialysis are at a higher risk of infection and mortality than the general population. Worldwide, a vaccination campaign has been developed that has been shown to reduce severe infections and deaths in the general population.

Objective: To raise awareness that patients with proximal ureteral stricture who elect for nephrectomy can consider donating the kidney. We present a series of patients undergoing therapeutic living donor nephrectomy (TLDN), a scenario in which a patient undergoing nephrectomy for an underlying medical problem donates the kidney to a person with end-stage renal disease. This practice is underutilized, and only a single TLDN with proximal ureteral stricture has been previously described.

Latinx youth, members of an ethnic minority group growing faster than the national growth rate, are at increased risk of experiencing adverse childhood experiences (ACEs) but it remains unclear how ACEs relate to externalizing behaviors, such as substance use and behaviors leading to injury and violence, in this population. In a sample of 100 Latinx youth, the current study examined how ACEs related to drug use and behaviors leading to injury and violence. Exposure to ACEs was associated with increased drug use, and that association was significantly moderated by behaviors leading to injury and violence for Latina adolescents.

Article Synopsis
  • Youth transitioning out of the foster care system often face challenges like homelessness and criminal behavior, but some manage to maintain resilience and succeed.
  • A systematic review of 12 studies identified 38 resilience factors, with 18 showing significant impact on positive outcomes for these youth.
  • Understanding these resilience factors can help clinicians support foster youth, guide researchers in developing interventions, and inform policymakers in creating laws that improve their life outcomes.

Colleges and universities are increasingly concerned about respect for diversity and tolerance of individual differences on their campuses. Nevertheless, no comprehensive measure of peer victimization has been developed and validated for use with college student populations. The Peer Victimization in College Survey (PVIC) is the first such measure.

Progesterone therapy is a viable treatment for complex atypical hyperplasia (CAH) and endometrial adenocarcinoma, though reliable molecular determinants of response are not available. To explore if analysis of pre-therapy endometrial biopsies could yield biomarkers of response to progesterone, patients with CAH or adenocarcinoma undergoing treatment with progestins were included in this cross-sectional study. Immunohistochemistry for progesterone receptor (PR) was performed.

Background: There have been few large-scale, real world studies in Spain to assess change in pain and quality of life (QOL) outcomes in cancer patients with moderate to severe pain. This study aimed to assess changes on both outcomes after 3 months of usual care and to investigate factors associated with change in QoL.

Patients And Methods: Large, multi-centre, observational study in patients with lung, head and neck, colorectal or breast cancer experiencing a first episode of moderate to severe pain while attending one of the participating centres.

Analysis of nine mouse monoclonal antibodies (mAbs) to the thyrotropin receptor (TSHR) with TSH antagonist activity showed that only one of the mAbs (RSR B2) was an effective antagonist of the human thyroid stimulating autoantibody M22. Crystals of B2 Fab were analyzed by x-ray diffraction and a crystal structure at 3.3 A resolution was obtained.
