In the opportunistic pathogen Pseudomonas aeruginosa, acyl-homoserine lactone (acyl-HSL) quorum sensing (QS) regulates biofilm formation and expression of many extracellular virulence factors. Curiously, QS-deficient variants, often carrying mutations in the central QS regulator LasR, are frequently isolated from infections, particularly from cystic(More)
Interleukin 23 receptor (IL23R) gene has been reported as a genetic factor strongly associated with inflammatory bowel disease, psoriasis, and ankylosing spondylitis. We investigated the association between IL23R gene single nucleotide polymorphisms (SNPs) and susceptibility to sarcoidosis, including the clinical manifestation of uveitis. Ninety-one(More)
We report a case of Cryptococcus neoformans pneumonia in a patient taking ruxolitinib, a janus kinase 1,2 inhibitor approved for the treatment of myelofibrosis. We hypothesize that ruxolitinib contributed to this infection through its effects on cell-mediated immunity. Clinicians should be aware of the potential for intracellular or opportunistic infections(More)
The T lymphocyte glycoprotein CD2 appears to have an important role in human T cell development and activation. A novel anti-CD2 monoclonal antibody, designed UMCD2, was shown to block E rosetting, and therefore was defined as recognizing the Tll1 ligand-binding epitope. Binding of UMCD2 to T cells and thymocytes was blocked by several, but not all,(More)
A 74-year-old man was referred to the pulmonary clinic for a right upper lobe mass on CT scan. He initially presented to his primary care provider 6 months prior with subacute onset of shortness of breath, sinus pressure, and fatigue. He was given azithromycin and fluticasone/salmeterol for communityacquired pneumonia and asthma, respectively, with(More)
BACKGROUND Eisenmenger physiology may contribute to abnormal pulmonary mechanics and gas exchange and thus impaired functional capacity. We explored the relationship between lung function and gas exchange parameters with exercise capacity and survival. METHODS Stable adult patients with Eisenmenger syndrome (N=32) were prospectively studied using(More)
OBJECTIVES Integrating audiological management into the care pathways of clinical specialties that prescribe ototoxic medications for essential, often life-preserving medical care that is critical for early hearing loss identification and remediation. Research shows that successful implementation of a new health service or intervention requires alignment of(More)
