Protocol for a randomized controlled trial of moderate intensity interval training in individuals with chronic obstructive pulmonary disease and obstructive sleep apnea overlap syndrome who have excessive daytime sleepiness.

Background: The term "Overlap Syndrome" (OS) describes the presence of both chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) in a single individual. Excessive daytime sleepiness (EDS) is a common symptom of OS shown to be associated with an increased risk of cardiovascular disease (CVD) that could be reduced through exercise. Thus, we propose to investigate a novel exercise intervention in individuals with the EDS-OS phenotype as they are at highest risk of CVD yet have the greatest barriers to exercise.

Estimating Web Survey Mode and Panel Effects in a Nationwide Survey of Alcohol Use.

Random-digit dialing (RDD) telephone surveys are challenged by declining response rates and increasing costs. Many surveys that were traditionally conducted via telephone are seeking cost-effective alternatives, such as address-based sampling (ABS) with self-administered web or mail questionnaires. At a fraction of the cost of both telephone and ABS surveys, opt-in web panels are an attractive alternative.

COPD: Providing the right treatment for the right patient at the right time.

Chronic Obstructive Pulmonary Disease (COPD) is a common disease associated with significant morbidity and mortality that is both preventable and treatable. However, a major challenge in recognizing, preventing, and treating COPD is understanding its complexity. While COPD has historically been characterized as a disease defined by airflow limitation, we now understand it as a multi-component disease with many clinical phenotypes, systemic manifestations, and associated co-morbidities.
