Intestinal current measurements (ICM) from rectal biopsies are a sensitive means to detect cystic fibrosis transmembrane conductance regulator (CFTR) function, but have not been optimized for multicenter use. We piloted multicenter standard operating procedures (SOPs) to detect CFTR activity by ICM and examined key questions for use in clinical trials. SOPs(More)
Background.  Delayed diagnosis of tuberculosis (TB) may lead to worse outcomes and additional TB exposures. Methods.  To estimate the potential number of misdiagnosed TB cases, we linked all hospital and emergency department (ED) visits in California's Healthcare Cost and Utilization Project (HCUP) databases (2005-2011). We defined a potential misdiagnosis(More)

The purpose of this paper was to estimate the risk of hospitalization for TB with and without a secondary diagnosis of diabetes in groups with different ethnic backgrounds. RESEARCH DESIGN AND METHODS We used the Nationwide Inpatient Sample from 1998 to 2011, identifying all patients with a(More)
BACKGROUND Inhaled hypertonic saline (HTS) improves quality of life and reduces pulmonary exacerbations when given long term in patients with cystic fibrosis (CF). While increasingly being offered for acute pulmonary exacerbations, little is known about the efficacy in this setting. OBJECTIVES The authors examined the tolerability and efficacy of HTS use(More)
