Oxalate or oxalic acid is a dicarboxylic acid formed in the human body from exogenous dietary sources and endogenous metabolism of ascorbic acid and some amino acids. It is essentially a terminal metabolic product that is produced by the liver, absorbed by the intestine from dietary sources, and freely filtered by the kidneys (Figure 1) (1). There is no human enzyme that can degrade it further.

Hepatic metabolism and dietary oxalate absorption generate plasma oxalate, which is then primarily excreted by kidneys into urine.
During the past few months, I have participated in several meetings that included in-depth discussions about the future of the health care workforce in the United States. Each time, the discussion started with predictions about shortages of every kind of health professional—from physicians to nurses to physician assistants/associates to other clinicians—and then shifted to concerns about the ability to provide high-quality patient care in the future as a result.
Although this editorial will focus on the future of nephrologists in the United States, I recognize that the situation is dire throughout the world, particularly for nurses. Earlier this year, the
The ASN Task Force on the Future of Nephrology was charged in April 2022 to reconsider all aspects of the future of nephrology and determine how to best prepare nephrology fellows for the challenges and opportunities the future will bring. Consisting of a diverse cross-section of ASN members, the task force will provide recommendations to the ASN Council by September 2022. The timeline will meet the commitment made by ASN to the American Board of Internal Medicine (ABIM) and the Accreditation Council for Graduate Medical Education (ACGME), as these organizations determine what changes should be made to nephrology certification and
Structural racism is a root cause of health inequities. The term structural racism refers to differential access by racial group to opportunities, resources, and societal well-being and is mediated through complex health care systems (1). To undergo kidney transplant, patients must navigate a multistep, conditional process that requires multiple health system and clinician interactions. This process exerts a differential burden on patients from marginalized groups. Studies in recent decades have demonstrated that racial minority groups experience lower rates of kidney transplant listing and transplant compared with patients of White race (2, 3). Patients of
Two recent studies published in CJASN address different aspects of the COVID-19 pandemic in adults with advanced kidney diseases: one examines whether prior COVID-19 vaccination affected the outcomes of individuals on dialysis who became infected with SARS-CoV-2 (1), and the other assesses the pandemic's impact on treatment decision-making for older patients with chronic kidney disease (CKD) (2).
People with CKD or other severe chronic medical conditions are at higher risk for more serious COVID-19 illness, and patients with kidney failure who rely on in-center hemodialysis face an elevated risk of becoming exposed to the

In 1964, the first kidney xenotransplant from a chimpanzee to human was performed successfully (1). Although the recipient survived 9 months, subsequent animal-to-human transplants were limited by immunologic barriers and the need for a sustainable organ source (2). Pigs soon became the ideal organ source because they produce large litters and mature rapidly, and availability is virtually unlimited (2, 3). Pigs have organs comparable in size and function with humans and lower risk of zoonoses, and their hormones and tissues are already used, suggesting positive public opinion (2, 3
ASN is retaining complete control over editorial content, strategy, and decisions while gaining technical, editorial, sales, and financial support. ASN will continue publishing cutting-edge nephrology science.
In a letter to HRSA, ASN emphasized the need for separating the technology portion of the OPTN contract as a stand-alone contract, requiring OPTN contractors to have complete and accurate data, and the enforcement of separate governance boards.
As we approach the middle of the year, those of us who live in locations with long, harsh winters are basking in the remainder of spring and its glorious diversity: multi-colored blossoms and greenery, rain, sun, and ever-changing temperatures. During my #850challenge (1) run this morning, I was struck how fitting it is that the joy of spring and oncoming summer coincides with Pride month—a month filled with opportunities to celebrate diversity and all the power and growth it brings to the kidney community.
Pride month is celebrated annually in June in the United States, culminating in festive
Over the past 10 to 20 years, there has been a revolution in the care of patients with cancer. In addition to classic chemotherapy agents, anti-cancer agents now include targeted therapies and immunotherapies, which harness the power of the immune system. These new therapies have transformed cancer into a chronic disease for many patients. Importantly, acute and chronic kidney diseases, electrolyte and acid-base disorders, and hypertension have become highly prevalent complications in this group of patients. This is particularly true for those with liver cancer, multiple myeloma, renal cell carcinoma, leukemias and lymphomas, and cancer patients treated with potentially nephrotoxic
