Diagnostic Contribution of Bronchoalveolar Lavage Sampling and Fungal Culture in a Dog With Pulmonary Coccidioidomycosis.

A 7-year-old, male neutered, Miniature Australian Shepherd from Arizona was presented for evaluation of a 3-month history of progressive cough. Thoracic radiographs revealed a focal alveolar pulmonary pattern and suspected tracheobronchial lymph node enlargement. Serum anti-Coccidioides spp.

Financial Burden in Blood or Marrow Transplantation Survivors During the COVID-19 Pandemic: A BMTSS Report.

Purpose: The financial burden experienced by blood or marrow transplant (BMT) survivors during the COVID-19 pandemic remains unstudied. We evaluated the risk for high out-of-pocket medical costs and associated financial burden experienced by BMT survivors and a sibling comparison group during the COVID-19 pandemic.

Methods: This study included 2,370 BMT survivors and 750 siblings who completed the BMT Survivor Study survey during the pandemic.

SARS-CoV-2 Anti-Spike IgG Antibody and ACE2 Receptor Binding Inhibition Levels among Breakthrough Stage Veteran Patients.

SARS-CoV-2 mRNA vaccines have been critical to curbing pandemic COVID-19; however, a major shortcoming has been the inability to assess levels of protection after vaccination. This study assessed serologic status of breakthrough infections in vaccinated patients at a Veterans Administration medical center from June through December 2021 during a SARS-CoV-2 delta variant wave. Breakthrough occurred mostly beyond 150 days after two-dose vaccination with a mean of 239 days.

Early trends in ECMO mortality during the first quarters of 2019 and 2020: Could we have predicted the onset of the pandemic?

Objective: To compare mortality trends in patients requiring Extracorporeal Membrane Oxygenation (ECMO) support between the first quarters of 2019 and 2020 and determine whether these trends might have predicted the severe acute respiratory syndrome coronavirus-2 (SARS)-Cov-2 pandemic in the United States.

Methods: We analyzed 5% Medicare claims data at aggregate, state, hospital, and encounter levels using MS-DRG (Medicare Severity-Diagnosis Related Group) codes for ECMO, combining state-level data with national census data. Necessity and sufficiency relations associated with change in mortality between the 2 years were modeled using qualitative comparative analysis (QCA).

Effect of monoclonal antibody therapy on the endogenous SARS-CoV-2 antibody response.

Monoclonal antibody treatment of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection has been widely implemented. Effects of treatment on the endogenous primary humoral response to the virus are unknown. A retrospective cohort study performed at a Veterans Health Administration medical center compared serologic responses of treated and untreated COVID-19 patients at high risk for severe outcomes.

Burden of Morbidity after Allogeneic Blood or Marrow Transplantation for Inborn Errors of Metabolism: A BMT Survivor Study Report.

Survival after blood or marrow transplantation (BMT) for inborn errors of metabolism (IEM) is excellent; however, the burden of morbidity in long-term survivors of BMT for IEM remains understudied. This study examined the risk of chronic health conditions (CHC) in ≥2-year survivors of allogeneic BMT for IEM performed between 1974 and 2014 using the BMT Survivor Study. In this retrospective cohort study, participants (or their parents; n = 154) reported demographic data and CHCs (graded using Common Terminology Criteria for Adverse Events version 5), and transplantation characteristics were obtained from institutional databases.

Trends in Late Mortality and Life Expectancy After Allogeneic Blood or Marrow Transplantation Over 4 Decades: A Blood or Marrow Transplant Survivor Study Report.

Importance: The past 4 decades have seen substantial changes in allogeneic blood or marrow transplantation (BMT) practice, with the overarching goal of expanding the eligible patient pool while optimizing disease-free survival.

Objective: To determine trends in life expectancy and cause-specific late mortality after allogeneic BMT performed over a 40-year period.

Design, Setting, And Participants: A retrospective cohort study of 4741 individuals who lived 2 or more years after allogeneic BMT performed between January 1, 1974, and December 31, 2014, was conducted at City of Hope, University of Minnesota, or University of Alabama at Birmingham.

Balancing the Roles of a Family Medicine Residency Faculty: A Grounded Theory Study.

Background And Objectives: Great variety exists in the roles that family medicine residency faculty fill in the lives of their residents. A family medicine-specific model has never been created to describe and promote effective training relationships. This research aims to create a consensus model for faculty development, ethics education, and policy creation.

Secreted immunodominant Mycobacterium tuberculosis antigens are processed by the cytosolic pathway.

Exposure to Mycobacterium tuberculosis can result in lifelong but asymptomatic infection in most individuals. Although CD8(+) T cells are elicited at high frequencies over the course of infection in both humans and mice, how phagosomal M. tuberculosis Ags are processed and presented by MHC class I molecules is poorly understood.

Hydrogen-bonding molecular ruler surfactants as probes of specific solvation at liquid/liquid interfaces.

Resonance-enhanced, second harmonic generation (SHG) is used to measure the electronic structure of solutes sensitive to specific solvation adsorbed to liquid/liquid and liquid/solid interfaces. Here, specific solvation refers to solvent-solute interactions that are directional and localized. N-methyl-p-methoxyaniline (NMMA) is a solute whose first allowed electronic transition wavelength remains almost constant (approximately 315 nm) in non-hydrogen-bonding solvents regardless of solvent polarity.

The Mycobacterium tuberculosis phagosome is a HLA-I processing competent organelle.

Mycobacterium tuberculosis (Mtb) resides in a long-lived phagosomal compartment that resists maturation. The manner by which Mtb antigens are processed and presented on MHC Class I molecules is poorly understood. Using human dendritic cells and IFN-gamma release by CD8(+) T cell clones, we examined the processing and presentation pathway for two Mtb-derived antigens, each presented by a distinct HLA-I allele (HLA-Ia versus HLA-Ib).
