Vulnerable populations, such as the elderly, children, displaced people, and refugees, often encounter challenges in accessing healthcare. In this study, we used data from the third iteration of the International Society of Nephrology Global Kidney Health Atlas (ISN-GKHA) to describe kidney care access and delivery to vulnerable populations across countries and regions. Using data from an international survey of clinicians, policymakers, and patient advocates, we assessed the funding and coverage of vulnerable populations on all aspects of kidney replacement therapies (KRT).

Introduction: There is a disparity in the availability of health care for children in resource-constrained countries. The International Pediatric Nephrology Association (IPNA) commissioned an initiative exploring the challenges in the care of children with kidney disease in low- or middle-income countries (LMICs) with a focus on human, diagnostic, and therapeutic resources.

Methods: A survey was sent by e-mail to all members of IPNA and its affiliated regional or national societies residing in LMICs.

Solid organ transplantation (SOT) is considered the optimal treatment for children with end-stage organ failure; however, increased efforts are needed to understand the gap surrounding equitable access to and health outcomes of SOT for Indigenous children. This scoping review summarizes the literature on the characteristics of access to and health outcomes of pediatric SOT among Indigenous children in the settler-colonial states of Canada, Aotearoa New Zealand, Australia, and the United States. A search was performed on MEDLINE, EMBASE, PsycINFO, and CINAHL for studies matching preestablished eligibility criteria from inception to November 2021.

Objectives: Because congenital anomalies of the kidneys and urinary tract (CAKUT) represent a frequent cause of end stage renal disease (ESRD) in the young, we explored the epidemiology of CAKUT and the role of diabetes in pregnancy.

Methods: This was a retrospective cohort study of CAKUT, by maternal diabetes status, from among all 1980‒2009 births in Saskatchewan First Nations (FN) and non-First Nations (non-FN) people. We determined frequencies, predictors and complications of CAKUT, as well as cumulative survival (to 2014) of affected persons until ESRD and death.

Background: Data guiding the timing of dialysis initiation in children are limited. We sought to determine current practice and secular trends in Canada with respect to the timing of dialysis initiation in children based on estimated glomerular filtration rate (eGFR).

Methods: This observational study included incident chronic dialysis patients aged ≤21 years identified from the Canadian Organ Replacement Register who started dialysis in Canada between January 2001 and December 2010 at any of the nine participating Canadian centers (n = 583).

Background: Significant practice variation exists in Canada with respect to timing of dialysis initiation in children. In the absence of evidence to guide practice, physicians' perceptions may significantly influence decision-making.

Objective: The objectives of this study are to (1) evaluate Canadian pediatric nephrologists' perceptions regarding dialysis initiation in children with chronic kidney disease (CKD) and (2) determine the factors guiding practice that may contribute to practice variation across Canada.

Background: Practice variation is common for nephrotic syndrome (NS) treatment.

Methods: A cross-sectional, web-based survey on NS treatment was administered to 58 Canadian pediatric nephrologists with the aim to document existing practice variation and compare practice with the recommendations of the Kidney Disease Improving Global Outcomes Clinical Practice Guideline for NS.

Results: Of the 58 nephrologists asked to participate in the survey, 40 (69 %) responded.

The amelogenin gene is tightly regulated at the temporal and spatial level in accord with the developmental requirement for tooth formation. Previous studies have shown that CCAAT/enhancer-binding protein alpha (C/EBPalpha) is a transactivator of the mouse X-chromosomal amelogenin gene. C/EBPalpha contains four highly conserved regions (CR) named CR1, CR2, CR3, and CR4.

Wnt signaling maintains preadipocytes in an undifferentiated state. When Wnt signaling is enforced, 3T3-L1 preadipocytes no longer undergo adipocyte conversion in response to adipogenic medium. Here we used microarray analyses to identify subsets of genes whose expression is aberrant when differentiation is blocked through enforced Wnt signaling.
