MedicalResearch.com: What is the background for this study?

Response: Androgen deprivation therapy is often deployed in patients with a rising PSA after local therapy (such as radical prostatectomy or radiation therapy). With time, the prostate cancer can develop resistance to ADT, at which point it is called castration resistant prostate cancer (CRPC). There were 6 treatments for metastatic CRPC that have shown improved survival. However, in non-metastatic disease, there was nothing that showed improved survival.

The SPARTAN study was designed to determine if a next generation androgen receptor antagonist could delay the time to metastatic disease. Overall survival was a secondary endpoint.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Obstructive sleep apnea (OSA) is associated with heart disease and mortality, but how OSA does this is not well understood. We are therefore looking for sub-phenotypes within OSA that will help us predict who is at greatest risk.

Current diagnosis of OSA is made on the basis of the apnea-hypopnea index (AHI – the number of respiratory events per hour of sleep). But the AHI is not a very good predictor of future mortality.

We tested the hypothesis that the duration of events (how long the breathing interruptions are) would predict risk. We found that those with the shortest breathing interruptions had the highest risk of dying, after accounting for other conditions like age, gender, race, and smoking status.  Continue reading
