The emergency department (ED) is a common setting for evaluation of patients with urolithiasis based on acute symptoms and a propensity for recurrent disease. We sought to characterize practice patterns in the emergency treatment of stone disease, and to identify potential disparities in care based on non-medical factors. We performed a cross-sectional analysis of ED visits using the National Hospital Ambulatory Medical Care Survey from 2005-2009. Visits with a diagnosis of urolithiasis were identified. The associations between patient, provider and institutional characteristics were analyzed with regard to timing of clinical assessment, use of diagnostic imaging, and use of medical expulsive therapy (MET). The likelihood of a delay in clinical assessment ranged from 30.8%-37.9%. Neither patient nor provider characteristics were associated with a delay in assessment, although urban location (p = 0.004) was more likely, and proprietary ownership was less likely (p = 0.002) to be associated with delay. Factors associated with use of CT included ambulance arrival (p = 0.043), initial ED visit (p = 0.000), and Northeast region (p = 0.030). Patients seen by a resident/intern were more likely to receive MET (p = 0.028). Overall, 10.8...Continue Reading

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.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

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.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
