The Barriers Assessment Tool—A Patient-Centered Measure of Adherence Barriers in Pediatric Kidney Transplantation

Objective: Assessing barriers to adherence provides helpful information to clinicians. The objective of this study was to describe the clinical utility of the Barriers Assessment Tool (BAT) using clinical data for a large, midwestern U.S. pediatric kidney transplant program. Methods: Focus group and clinical data were obtained during post-transplant medical visits. Qualitative and quantitative assessment methods were utilized to describe patient and caregiver feedback on the BAT, clinical utility, concordance between reporters, and the effect of interventions on subsequent assessment and electronically measured adherence. Results: Patients were willing to discuss adherence issues with their care team. There was substantial agreement between patients and caregivers at two timepoints. If a barrier was not addressed, 89.6% (43/48) of patients and 85.9% (67/78) of caregivers reported the same BAT scores from the first to second assessment. When barriers were addressed with a clinic-based intervention, 82% of caregivers reported no adherence barriers. No significant change was found for patient-reported barriers. Conclusions: Standardized assessment of barriers to medication adherence provides actionable information to clinicians. Standardized assessment of adherence barriers may give clinicians opportunities to help patients and caregivers overcome these barriers which can decrease risk of rejection

Revealing the Role of the Metal in Non-Precious-Metal Catalysts for Oxygen Reduction via Selective Removal of Fe

Non-precious-metal catalysts have been investigated as alternatives to Pt-based oxygen reduction reaction catalysts for more than 50 years. While the incorporation of a metal is known to be necessary to generate a catalyst with high activity, the exact role of the metal is still not well-understood. In this work, we prepare an active oxygen reduction reaction catalyst containing Fe and then selectively remove the Fe from the catalyst while preserving the carbon and nitrogen species. By comparing the oxygen reduction reaction activity of the catalyst before and after treatment, we show that in the absence of Fe the carbon and nitrogen sites in the catalyst exhibit a larger overpotential and lower selectivity for the 4<i>e</i>^– reduction of oxygen in both acidic and alkaline conditions. These findings reveal the direct involvement of the metal in the active site of non-precious-metal catalysts and provide important guidance for future catalyst improvements

Impact of the COVID-19 pandemic on the kidney community: lessons learned and future directions.

The coronavirus disease 2019 (COVID-19) pandemic has disproportionately affected patients with kidney disease, causing significant challenges in disease management, kidney research and trainee education. For patients, increased infection risk and disease severity, often complicated by acute kidney injury, have contributed to high mortality. Clinicians were faced with high clinical demands, resource shortages and novel ethical dilemmas in providing patient care. In this review, we address the impact of COVID-19 on the entire spectrum of kidney care, including acute kidney injury, chronic kidney disease, dialysis and transplantation, trainee education, disparities in health care, changes in health care policies, moral distress and the patient perspective. Based on current evidence, we provide a framework for the management and support of patients with kidney disease, infection mitigation strategies, resource allocation and support systems for the nephrology workforce

COVID-19 in pediatric kidney transplantation: a follow-up report of the Improving Renal Outcomes Collaborative

BackgroundWe report follow-up data from an ongoing prospective cohort study of COVID-19 in pediatric kidney transplantation through the Improving Renal Outcomes Collaborative (IROC).MethodsPatient-level data from the IROC registry were combined with testing, indication, and outcomes data collected to describe the epidemiology of COVID testing, treatment, and clinical outcomes; determine the incidence of a positive COVID-19 test; describe rates of COVID-19 testing; and assess for clinical predictors of a positive COVID-19 test.ResultsFrom September 2020 to February 2021, 21 centers that care for 2690 patients submitted data from 648 COVID-19 tests on 465 patients. Most patients required supportive care only and were treated as outpatients, 16% experienced inpatient care, and 5% experienced intensive care. Allograft complications were rare, with acute kidney injury most common (7%). There was 1 case of respiratory failure and 1 death attributed to COVID-19. Twelve centers that care for 1730 patients submitted complete testing data on 351 patients. The incidence of COVID-19 among patients at these centers was 4%, whereas the incidence among tested patients was 19%. Risk factors to predict a positive COVID-19 test included age &gt; 12&nbsp;years, symptoms consistent with COVID-19, and close contact with a confirmed case of COVID-19.ConclusionsDespite the increase in testing and positive tests over this study period, the incidence of allograft loss or death related to COVID-19 remained extremely low, with allograft loss or death each occurring in &lt; 1% of COVID-19-positive patients and in less than &lt; 0.1% of all transplant patients within the IROC cohort.
