Thiamine Deficiency Is Common and Underrecognized in Emergency Department Oncology Patients.

: Wernicke's encephalopathy can occur in oncology patients independent of alcohol use, likely resulting from poor dietary thiamine intake. High metabolic demands, such as those in acute illnesses seen in the emergency department (ED), can exacerbate thiamine deficiency. In this study, our objective was to assess the incidence of thiamine deficiency in ED oncology patients, which could lead to Wernicke's encephalopathy or other thiamine deficiency disorders if left untreated.

An early precursor CD8 T cell that adapts to acute or chronic viral infection.

This study examines the origin and differentiation of stem-like CD8+ T cells that are essential for sustained T cell immunity in chronic viral infections and cancer and also play a key role in PD-1 directed immunotherapy. These PD-1+ TCF-1+ TOX+ stem-like CD8+ T cells, also referred to as precursors of exhausted T cells, have a distinct program that allows them to adapt to chronic antigen stimulation. Using the mouse model of chronic LCMV infection we found that virus specific stem-like CD8+ T cells are generated early (day 5) during chronic infection suggesting that this crucial fate commitment occurs irrespective of infection outcome.

Molecular Profiling of Biliary Tract Cancers in African American and Caucasian Patients.

Purpose: Biliary tract cancers (BTCs) include intrahepatic cholangiocarcinoma (ICC), extrahepatic cholangiocarcinoma (ECC), and gallbladder cancers. BTCs have a number of genomic alterations, including isocitrate dehydrogenase 1 () mutations, fibroblast growth factor receptor 2 () rearrangements, and amplifications. Therapies targeting these alterations have shown clinical benefit in patients with BTCs in the United States.

Assessing Medicare's Coverage With Evidence Development Program.

The Centers for Medicare and Medicaid Services (CMS) coverage with evidence development (CED) program provides coverage for items and services not meeting Medicare's "reasonable and necessary" standard while requiring participation in clinical studies. As additional evidence is available, CMS may reconsider CED decisions. Of twenty-six items and services in the CED program since its 2005 inception, CMS has reconsidered coverage for ten (38 percent).

Minimal domain peptides derived from enterocins exhibit potent antifungal activity.

The antimicrobial peptide (AMP) circularized bacteriocin enterocin AS-48 produced by sp. exhibits broad-spectrum antibacterial activity via dimer insertion into the plasma membrane to form membrane pore structures, compromising membrane integrity and leading to bactericidal activity. A specific alpha-helical region of enterocin AS-48 has been shown to be responsible for the membrane-penetrating activity of the peptide.
