Cancer-related problems, sleep quality, and sleep disturbance among long-term cancer survivors at 9-years post diagnosis.

Objective: To estimate the prevalence of sleep difficulties in a large cohort of long-term cancer survivors (>5 years) and examine associations with four domains of cancer-related problems.

Methods: This study analyzed a nationwide sample (N = 1903) of cancer survivors (31% Breast; 20% prostate) at nine years (m = 8.9 sd = 0.

The Burden of Pulmonary Nontuberculous Mycobacterial Disease in the United States.

Rationale: State-specific case numbers and costs are critical for quantifying the burden of pulmonary nontuberculous mycobacterial disease in the United States.

Objectives: To estimate and project national and state annual cases of nontuberculous mycobacterial disease and associated direct medical costs.

Methods: Available direct cost estimates of nontuberculous mycobacterial disease medical encounters were applied to nontuberculous mycobacterial disease prevalence estimates derived from Medicare beneficiary data (2003-2007).
