Clinicopathologic characteristics of myeloproliferative neoplasms with JAK2 exon 12 mutation.

The presence of JAK2 exon 12 mutation was included by the 2016 World Health Organization (WHO) Classification as one of the major criteria for diagnosing polycythemia vera (PV). Few studies have evaluated the clinical presentation and bone marrow morphology of these patients and it is unclear if these patients fulfill the newly published criteria of 5th edition WHO or The International Consensus Classification (ICC) criteria for PV. Forty-three patients with JAK2 exon 12 mutations were identified from the files of 7 large academic institutions.

Improved oral health knowledge in a primary care pediatric nurse practitioner program.

Pediatric nurse practitioners (PNPs) are a significant workforce in primary care and are uniquely positioned to improve oral health in children through ongoing surveillance in the well-child visit. The purpose of this study was to evaluate PNP student satisfaction and knowledge gained with the integration of the Strategic Partnership for Interprofessional Collaborative Education in Pediatric Dentistry (SPICE-PD) oral health education program into the first-year primary care curriculum. A descriptive, comparative design examined dental test scores across the pre-SPICE-PD (2013-2014; n = 26) and post-SPICE-PD (2015-2020; n = 55) cohorts.

Transcriptomics reveal different metabolic strategies for acid resistance and gamma-aminobutyric acid (GABA) production in select Levilactobacillus brevis strains.

Background: Of the many neurotransmitters in humans, gamma-aminobutyric acid (GABA) shows potential for improving several mental health indications such as stress and anxiety. The microbiota-gut-brain axis is an important pathway for GABAergic effects, as microbially-secreted GABA within the gut can affect host mental health outcomes. Understanding the molecular characteristics of GABA production by microbes within the gut can offer insight to novel therapies for mental health.
