This research paper explores the use of performance-based acquisition (PBA) techniques when contracting for services on a level-of-effort (LOE) basis. The research explores how often and how effectively these two concepts are used together in the Navy. This project examines the following questions: 1. Can PBA techniques and LOE contract types be used together effectively, or is there a natural ...

BACKGROUND Recent longitudinal work suggests that weight change is an important risk factor for inflammation across the full range of BMI. However, few studies have examined whether the risk of inflammation differs by patterns of weight gain over time. Using latent class trajectory analysis, we test whether patterns of weight gain are associated with elevated high-sensitivity C-reactive protein...

In Riedel’s thyroiditis, a rare chronic inflammatory disease of thyroid gland, fine needle aspiration is usually non-diagnostic because most often only follicular cells are obtained and not the fibrous material characteristic of this type of thyroiditis. Therefore the diagnosis is often only established by histopathologic study of the surgically obtained biopsy. The illustrated case is a 46-yea...

BACKGROUND AND PURPOSE Efforts to make physical therapy more evidence based have increased demand for human participants, raising concerns for their safety and welfare. This study examined how often research articles in physical therapy journals report basic ethical protections. METHODS We carried out a retrospective audit of research articles in 6 physical therapy journals between 1996 and 2...
