Identification and outcomes of acute kidney disease in patients presenting in Bolivia, Brazil, South Africa, and Nepal.

Background: The International Society of Nephrology proposes an acute kidney disease (AKD) management strategy that includes a risk score to aid AKD identification in low- and low-middle-income countries (LLMICs). We investigated the performance of the risk score and determined kidney and patient outcomes from AKD at multiple LLMIC sites.

Methods And Findings: Adult patients presenting to healthcare facilities in Bolivia, Brazil, South Africa, and Nepal were screened using a symptom-based risk score and clinical judgment.

ENHANCE: a comparative prospective longitudinal study of cognitive outcomes after 3 years of hearing aid use in older adults.

Background: With an aging population, the prevalence of hearing loss and dementia are increasing rapidly. Hearing loss is currently considered the largest potentially modifiable risk factor for dementia. The effect of hearing interventions on cognitive function should therefore be investigated, as if effective, these may be successfully implemented to modify cognitive outcomes for older adults with hearing loss.

Efficacy of beetroot juice on reducing blood pressure in hypertensive adults with autosomal dominant polycystic kidney disease (BEET-PKD): study protocol for a double-blind, randomised, placebo-controlled trial.

Background: In autosomal dominant polycystic kidney disease (ADPKD) impaired nitric oxide (NO) synthesis, in part, contributes to early-onset hypertension. Beetroot juice (BRJ) reduces blood pressure (BP) by increasing NO-mediated vasodilation. The aim of this double-blind, randomised, placebo-controlled study is to test the hypothesis that BRJ reduces systolic and diastolic clinic BP in hypertensive adults with ADPKD.

National health policies and strategies for addressing chronic kidney disease: Data from the International Society of Nephrology Global Kidney Health Atlas.

National strategies for addressing chronic kidney disease (CKD) are crucial to improving kidney health. We sought to describe country-level variations in non-communicable disease (NCD) strategies and CKD-specific policies across different regions and income levels worldwide. The International Society of Nephrology Global Kidney Health Atlas (GKHA) was a multinational cross-sectional survey conducted between July and October 2018.

Batkoa major infecting the invasive planthopper Lycorma delicatula.

The entomopathogenic fungi Batkoa major and Beauveria bassiana caused co-epizootics in populations of invasive spotted lanternflies, Lycorma delicatula, in 2018 in northeastern North America. Although first described from North America in 1888, the biology and ecology of Batkoa major had not been studied since that time. This entomophthoralean fungus found infecting L.

No Influence of Age-Related Hearing Loss on Brain Amyloid-β.

Background: Hearing loss is independently associated with a faster rate of cognitive decline in older adults and has been identified as a modifiable risk factor for dementia. The mechanism for this association is unknown, and there has been limited exploration of potential casual pathology.

Objective: Our objective was to investigate whether there was an association between degree of audiometrically measured hearing loss (HL) and brain amyloid-β (Aβ) in a pre-clinical sample.

Global Estimates of Capacity for Kidney Transplantation in World Countries and Regions.

Background: Kidney transplantation (KT) is the optimal treatment for kidney failure and is associated with better quality of life and survival relative to dialysis. However, knowledge of the current capacity of countries to deliver KT is limited. This study reports on findings from the 2018 International Society of Nephrology Global Kidney Health Atlas survey, specifically addressing the availability, accessibility, and quality of KT across countries and regions.

Current status of health systems financing and oversight for end-stage kidney disease care: a cross-sectional global survey.

Objectives: The Global Kidney Health Atlas (GKHA) is a multinational, cross-sectional survey designed to assess the current capacity for kidney care across all world regions. The 2017 GKHA involved 125 countries and identified significant gaps in oversight, funding and infrastructure to support care for patients with kidney disease, especially in lower-middle-income countries. Here, we report results from the survey for the second iteration of the GKHA conducted in 2018, which included specific questions about health financing and oversight of end-stage kidney disease (ESKD) care worldwide.

Promotion of β-Catenin/Forkhead Box Protein O Signaling Mediates Epithelial Repair in Kidney Injury.

Fibrosis is characterized by progressively excessive deposition of matrix components and may lead to organ failure. Transforming growth factor-β (TGF-β) is a key cytokine involved in tissue repair and fibrosis. TGF-β's profibrotic signaling pathways converge at activation of β-catenin.

Availability, coverage, and scope of health information systems for kidney care across world countries and regions.

Background: Health information systems (HIS) are fundamental tools for the surveillance of health services, estimation of disease burden and prioritization of health resources. Several gaps in the availability of HIS for kidney disease were highlighted by the first iteration of the Global Kidney Health Atlas.

Methods: As part of its second iteration, the International Society of Nephrology conducted a cross-sectional global survey between July and October 2018 to explore the coverage and scope of HIS for kidney disease, with a focus on kidney replacement therapy (KRT).

Availability, Accessibility, and Quality of Conservative Kidney Management Worldwide.

Background And Objectives: People with kidney failure typically receive KRT in the form of dialysis or transplantation. However, studies have suggested that not all patients with kidney failure are best suited for KRT. Additionally, KRT is costly and not always accessible in resource-restricted settings.

Rate of decline in residual kidney function pre and post peritoneal dialysis initiation: A post hoc analysis of the IDEAL study.

Background: Residual kidney function (RKF) is associated with improved survival and quality of life in dialysis patients. Previous studies have suggested that initiation of peritoneal dialysis (PD) may slow RKF decline compared to the pre-dialysis period. We sought to evaluate the association between PD initiation and RKF decline in the Initiating Dialysis Early And Late (IDEAL) trial.

IL-10 producing type 2 innate lymphoid cells prolong islet allograft survival.

Type 2 innate lymphoid cells (ILC2s) are a subset of ILCs with critical roles in immunoregulation. However, the possible role of ILC2s as immunotherapy against allograft rejection remains unclear. Here, we show that IL-33 significantly prolonged islet allograft survival.

Renal tubular cell binding of β-catenin to TCF1 versus FoxO1 is associated with chronic interstitial fibrosis in transplanted kidneys.

β-Catenin is an important co-factor which binds multiple transcriptional molecules and mediates fibrogenic signaling pathways. Its role in kidney transplantation is unknown. We quantified binding of β-catenin within renal tubular epithelial cells to transcription factors, TCF1 and FoxO1, using a proximity ligation assay in 240 transplanted kidneys, and evaluated their pathological and clinical outcomes.

Peritoneal Dialysis Use and Practice Patterns: An International Survey Study.

Rationale & Objective: Approximately 11% of people with kidney failure worldwide are treated with peritoneal dialysis (PD). This study examined PD use and practice patterns across the globe.

Study Design: A cross-sectional survey.

Hemodialysis Use and Practice Patterns: An International Survey Study.

Rationale & Objective: Hemodialysis (HD) is the most common form of kidney replacement therapy. This study aimed to examine the use, availability, accessibility, affordability, and quality of HD care worldwide.

Study Design: A cross-sectional survey.

Effects of Allopurinol on the Progression of Chronic Kidney Disease.

Background: Elevated serum urate levels are associated with progression of chronic kidney disease. Whether urate-lowering treatment with allopurinol can attenuate the decline of the estimated glomerular filtration rate (eGFR) in patients with chronic kidney disease who are at risk for progression is not known.

Methods: In this randomized, controlled trial, we randomly assigned adults with stage 3 or 4 chronic kidney disease and no history of gout who had a urinary albumin:creatinine ratio of 265 or higher (with albumin measured in milligrams and creatinine in grams) or an eGFR decrease of at least 3.

The role of DNA damage as a therapeutic target in autosomal dominant polycystic kidney disease.

Autosomal dominant polycystic kidney disease (ADPKD) is the most common monogenic kidney disease and is caused by heterozygous germ-line mutations in either PKD1 (85%) or PKD2 (15%). It is characterised by the formation of numerous fluid-filled renal cysts and leads to adult-onset kidney failure in ~50% of patients by 60 years. Kidney cysts in ADPKD are focal and sporadic, arising from the clonal proliferation of collecting-duct principal cells, but in only 1-2% of nephrons for reasons that are not clear.

Status of care for end stage kidney disease in countries and regions worldwide: international cross sectional survey.

Objective: To determine the global capacity (availability, accessibility, quality, and affordability) to deliver kidney replacement therapy (dialysis and transplantation) and conservative kidney management.

Design: International cross sectional survey.

Setting: International Society of Nephrology (ISN) survey of 182 countries from July to September 2018.

Promotion of β-catenin/Foxo1 signaling ameliorates renal interstitial fibrosis.

Transforming growth factor β (TGF-β) is the key cytokine involved in causing fibrosis through cross-talk with major profibrotic pathways. However, inhibition of TGF-β to prevent fibrosis would also abrogate its anti-inflammatory and wound-healing effects. β-catenin is a common co-factor in most TGF-β signaling pathways.

Global capacity for clinical research in nephrology: a survey by the International Society of Nephrology.

Due to the worldwide rising prevalence of chronic kidney disease (CKD), there is a need to develop strategies through well-designed clinical studies to guide decision making and improve delivery of care to CKD patients. A cross-sectional survey was conducted based on the International Society of Nephrology Global Kidney Health Atlas data. For this study, the survey assessed the capacity of various countries and world regions in participating in and conducting kidney research.

Global coverage of health information systems for kidney disease: availability, challenges, and opportunities for development.

Development and planning of health care services requires robust health information systems to define the burden of disease, inform policy development, and identify opportunities to improve service provision. The global coverage of kidney disease health information systems has not been well reported, despite their potential to enhance care. As part of the Global Kidney Health Atlas, a cross-sectional survey conducted by the International Society of Nephrology, data were collected from 117 United Nations member states on the coverage and scope of kidney disease health information systems and surveillance practices.
