Validity of microscopy for diagnosing urinary tract infection in general practice - a systematic review.

To investigate the validity of microscopy as a diagnostic tool for urinary tract infection in general practice. (Design/setting) A systematic review was conducted by searching Medline for clinical studies made in general practice, outpatient clinics or similar settings in which the accuracy/validity of microscopy was evaluated with urine culture as the reference standard. Our search resulted in 108 titles.

Social support is associated with technology use in old age.

Background: The use of technological innovations can play a significant role in healthy aging and social participation in old age; however, it is not well understood how social contexts can influence or support older adults' use of technology. This study explored the associations between technology use, perceived technology-related support and actual technology-related social support. It was expected that older adults who perceived having more supportive resources available would be more likely to receive actual support in technology-related issues, which, in turn would explain a greater use of technology in everyday life.

Subjective Technology Adaptivity Predicts Technology Use in Old Age.

Background: To date, not much is known about the psychological and motivational factors underlying technology use in late life. What are the interindividual determinants that lead older adults to invest in using technological innovations despite the age-related physiological changes that impose challenges on behavioral plasticity in everyday life?

Objective: This research explores interindividual differences in subjective technology adaptivity - a general technology-related motivational resource that accounts for technology use in late life. More specifically, we investigate the influence of this factor relative to demographic characteristics, personality traits, and functional limitations in a longitudinal sample of community-dwelling older adults.

[Subjective time left in life and precautionary relocation planning in the last half of life].

Background: Many people wish to remain in current residence for as long as possible. Nonetheless, they do think about their residential future. For older people the question of where to live must be considered with respect to age-related changes and continuity.

Outdoor motivation moderates the effects of accessibility on mobility in old age.

Background: Mobility plays a major role in healthy aging and social participation. This study explored whether accessibility problems in the housing environment are negatively associated with mobility in old age and whether this association is moderated by differences in an individual's preference for spending time outside the home (outdoor motivation).

Material And Methods: This article reports the results of a research project on mobility in old age.

K+-ATP-channel-related protein complexes: potential transducers in the regulation of epithelial tight junction permeability.

K(+)-ATP channels are composed of an inwardly rectifying Kir6 subunit and an auxiliary sulfonylurea receptor (SUR) protein. The SUR subunits of Kir6 channels have been recognized as an ATPase, which appears to work as a mechanochemical device like other members of the ABC protein family. Thus, in spite of just gating ions, Kir6/Sur might, in addition, regulate completely different cellular systems.
