In this study, both a questionnaire survey and a functional assessment were performed. The results were examined to clarify factors which might influence clinical symptoms in patients with surgical repairs following complete rotator cuff tear. In addition, evidence on which to base postoperative activities of daily living and rehabilitation was elucidated. The percentage of patients with satisf...

BACKGROUND In older adults hospitalized for heart failure, a poor score on a comprehensive geriatric assessment (CGA) is associated with worse prognosis during hospitalization and at 1 month after discharge. However, the association between the CGA score and long-term mortality is uncertain. METHODS AND RESULTS This is a prospective study of 487 patients aged ≥75 years admitted for decompensa...

BACKGROUND As an important outcome measure among rheumatoid arthritis (RA) patients, functional disability may contribute to unemployment, loss of work productivity, and impaired quality of life.

Ammonia-oxidizing microbes control the rate-limiting step of nitrification, a critical ecosystem process, which affects retention and mobility of nitrogen in soil ecosystems. This study investigated substrate (NH4þ) and nutrient (K and P) limitation of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) in temperate forest soils at Coweeta Hydrologic Laboratory, a long-term eco...

BACKGROUND Ageing is associated with a decline of motor function and ability to perform daily activities. Locomotive disorders are one of the major disorders resulting in adverse health condition in elderly people. Concept of Locomotive syndrome (LoS) was proposed to tackle the problems and prolong healthy life expectancy of people with locomotive disorders. To develop intervention strategy for...
