Cryptococcal Antigen Testing In An Integrated Medical System: Eastern Wisconsin, Marianne Klumph, Brian Hoeynck, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

Cryptococcosis is a serious environmentally acquired endemic fungal infection commonly associated with immunocompromised hosts. Little is known regarding frequency or distribution in Wisconsin. We explored the geodemographic and clinical features of patients tested with cryptococcal antigen tests (CrAg) — previously shown to be >90% sensitive and >90% specific — within a large health care system located in eastern Wisconsin. To examine this, we retrospectively analyzed 1465 CrAg tests on 1211 unique patients (female: 50.2%; white race: 73.9%; mean age: 53.7 ± 16.5 years). At least one CrAg result was positive in 23 of 1211 patients (1.9%). From these, 21 of …

Antiresorptive Bone Therapy Use In Advanced Lung Cancer And Associated Outcomes, Noor Naffakh

Theses and Dissertations--Pharmacy

Background/Rationale: Studies have shown antiresorptive agents decrease skeletal related events in metastatic non-small cell lung cancer. However, two prevalence studies have found low utilization rates of antiresorptive therapy in advanced lung cancer. The first study reported a rate of 14.8% during the 1995-2009 time period, while the second study reported a 33% usage rate during the time frame of 2002-2011. We believe these low utilization rates are associated with the poor prognosis of these patients. The prognosis of advanced lung cancer has improved significantly since these trials were conducted, and the utilization of denosumab has not been evaluated. We hypothesize …
