Functional dyspepsia: How to manage the burn and the bloat.

Functional dyspepsia is defined as persistent symptoms of postprandial bloating, early satiety, or pain in the center of the upper abdomen, without findings on upper endoscopy such as peptic ulcer disease to explain these symptoms. It is common, affecting up to 30% of the global population, but it often goes undiagnosed for years. There are 2 subtypes: epigastric pain syndrome (burning and pain) and postprandial distress syndrome (bloating and satiety).

Combinatorially restricted computational design of protein-protein interfaces to produce IgG heterodimers.

Redesigning protein-protein interfaces is an important tool for developing therapeutic strategies. Interfaces can be redesigned by in silico screening, which allows for efficient sampling of a large protein space before experimental validation. However, computational costs limit the number of combinations that can be reasonably sampled.

PCRRT-ICONIC critical care pediatric nephrology course: the global prevalence of COVID-19 and associated sequelae.

After nearly three years of the COVID-19 pandemic, research has affirmed that COVID-19 is more than just a respiratory virus. There have been significant breakthroughs made surrounding the development of acute kidney injury (AKI) and chronic kidney disease (CKD), in pediatric populations. Additionally, patient populations susceptible to renal complications consist of pediatric transplant recipients, multisystem inflammatory syndrome (MIS-C), and dialysis.

Cardiovascular implications in adolescent and young adult hypertension.

Background: Hypertension is one of the most prevalent diseases in the United States, affecting an estimated 3.5% of children and adolescents. It can be adversely affect most organ systems but is particularly detrimental to the heart and vascular systems.

PCRRT Expert Committee ICONIC Position Paper on Prescribing Kidney Replacement Therapy in Critically Sick Children With Acute Liver Failure.

Management of acute liver failure (ALF) and acute on chronic liver failure (ACLF) in the pediatric population can be challenging. Kidney manifestations of liver failure, such as hepatorenal syndrome (HRS) and acute kidney injury (AKI), are increasingly prevalent and may portend a poor prognosis. The overall incidence of AKI in children with ALF has not been well-established, partially due to the difficulty of precisely estimating kidney function in these patients.

Pediatric Atypical Hemolytic Uremic Syndrome Advances.

Atypical hemolytic uremic syndrome (aHUS) is a rare disorder characterized by dysregulation of the alternate pathway. The diagnosis of aHUS is one of exclusion, which complicates its early detection and corresponding intervention to mitigate its high rate of mortality and associated morbidity. Heterozygous mutations in complement regulatory proteins linked to aHUS are not always phenotypically active, and may require a particular trigger for the disease to manifest.
