Abstract

To determine which risk factors help predict recurrent stone formation. Urinary stone disease is relatively rare in children. At our institution, a full urinary metabolic evaluation is initiated after the first stone episode. A retrospective cohort study was performed to assess urinary metabolic profiles in children with urolithiasis. Twenty-four-hour urine collections were performed and evaluated. Urine chemistries were adjusted for creatinine and weight. Abnormal thresholds were obtained from the available published data. The patients were stratified into solitary or recurrent stone formers by review of the medical record. Multivariate analysis was performed with a logistic regression model to assess for independent risk factors for stone recurrence. A total of 148 samples from 88 patients with solitary stones and 84 samples from 51 patients with recurrent stones were evaluated. Age and gender were well-matched between the 2 groups. Most known stones were calcium oxalate, and there were no radiolucent stones in those with unknown composition. A significantly higher number of patients with recurrent stones had abnormal values for calcium (73% vs 57%) and citrate (30% vs 13%) by univariate analysis. Both calcium (odds ratio, 2....Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
