Predictors of mortality in patients with delirium tremens

The objectives were to identify factors that may help predict mortality for patients with delirium tremens (DT). The authors conducted a 1:1 gender- and age-matched case-control study of patients hospitalized for DT. Using McNemar chi-square tests and conditional logistic regression (CLR), risk factors for death, including demographics, location of diagnosis, vital sign derangements, treatment methods, and comorbid conditions, were evaluated. Crude and adjusted odds ratios (OR) and 95% confidence intervals (CI) are reported. Thirty-five patients with DT died between January 2000 and June 2006. The majority (31; 88.6%) were male with a mean (+/-standard deviation [SD]) age of 51.7 (+/-7.6) years. Hyperthermia in the first 24 hours of DT diagnosis (OR = 10.0, 95% CI = 2.3 to 42.7), persistent tachycardia (OR = 24.0, 95% CI = 3.3 to 177.4), and use of restraints (OR = 7.50, 95% CI = 1.7 to 32.8) were associated with increased mortality by univariate analysis, while an emergency department (ED) diagnosis of DT (OR = 0.18, 95% CI = 0.05 to 0.6) and use of clonidine (OR = 0.10, 95% CI = 0.01 to 0.78) were associated with decreased mortality. In the CLR model, restraint use and hyperthermia were the only variables that remained signif...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.
