Numerous studies have documented poor cardiopulmonary resuscitation (CPR) performance among prehospital providers during both simulated and actual resuscitations. Previous studies have shown that a real-time, voice assist manikin (VAM) system may improve CPR performance. To determine whether VAM prompting would improve CPR performance by prehospital providers during simulated resuscitation. In this prospective, randomized, crossover design, 114 prehospital providers performed two 3-minute sessions of one-rescuer CPR on a VAM-resuscitation manikin: one round with the VAM feature turned on and one with the feature turned off. The primary outcomes were measured at 15-second intervals and included the fraction of correct compressions, the mean compression depth, the fraction of correct ventilations, and the mean ventilation tidal volume. Generalized estimating equations were used to analyze the repeated measures. The VAM prompting was not directly associated with correct compressions during one-rescuer CPR in a cohort of subjects naïve to the system. However, the general decay in correct compressions seen over 3 minutes was attenuated with VAM prompting. Neither the compression depth nor the decay in compression depth over time was...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.
