A pilot randomized controlled trial of CAPABLE in permanent supportive housing for formerly homeless adults.

BACKGROUND: CAPABLE is a time-limited, evidence-based intervention that helps older adults live independently. It has not been previously tested for use among formerly homeless adults in permanent supportive housing (PSH) who experience accelerated aging that can jeopardize their ability to live independently and age in place. METHODS: A pilot randomized controlled trial with PSH tenants with an average age of 63 years old was conducted to examine the impact of CAPABLE on basic and instrumental activities of daily living (ADL) (and other function-related parameters). Twenty-seven PSH tenants received the intervention and 30 PSH tenants were assigned to a waitlist control group. RESULTS: Those who received the intervention showed improvements in five of seven health outcomes with small to medium effect sizes (Cohen's d = 0.20-0.47). When compared to the control group, the intervention group showed significantly greater improvements in two health outcomes-namely, reduction in limitations in instrumental ADL (p = 0.03) and depression (p = 0.01)-and greater effect sizes (d = 0.17-0.61). CONCLUSIONS: CAPABLE is an evidence-based practice that can be successfully implemented in PSH to improve outcomes in a population that experiences significant health disparities and premature decline. Further investigation with a larger sample is warranted.

Evaluation of air quality by passive and active sampling in an urban city in Turkey: current status and spatial analysis of air pollution exposure.

Concentrations of air pollutants, nitrogen dioxide (NO(2)), sulfur dioxide (SO(2)), ozone (O(3)), particulate matter (PM(2.5) and PM(10)), trace metals, and polycyclic aromatic hydrocarbons (PAHs) were measured in 2008 and 2009 in the city of Eskisehir, central Turkey. Spatial distributions of NO(2), SO(2), and ozone were determined by passive sampling campaigns carried out during two different seasons with fairly large spatial coverage. A basic population exposure assessment was carried out employing Geographical Information System techniques by combining population density maps with pollutant distribution maps of NO(2) and SO(2). It was found that 95 % of the population is exposed to NO(2) levels close to the World Health Organization guideline value. Regarding SO(2), a large proportion of the population (83 %) is exposed to levels above the WHO second interim target value. Concentrations of all the pollutants showed a seasonal pattern increasing in winter period, except for ozone having higher concentrations in summer season. Daily PM(10) and PM(2.5) concentrations exceeded European Union limit values almost every sampling day. Toxic fractions of the measured PAHs were calculated and approximately fourfold increase was observed in winter period. Copper, Pb, Sn, As, Cd, Zn, Sb, and Se were found to be moderately to highly enriched in PM(10) fraction, indicating anthropogenic input to those elements measured. Exposure assessment results indicate the need for action to reduce pollutant emissions especially in the city center. Passive sampling turns out to be a practical and economical tool for air quality assessment with large spatial coverage.

Multivariate statistics to investigate metal contamination in surface soil.

The modification of soil composition in the urbanized area of Ankara due to wet-dry deposition and pollution-derived particles from the atmosphere is investigated by analyzing 120 surface soil samples, collected from the urbanized area and its un-urbanized surrounding, for major, minor and trace elements. Concentrations of elements from human activity (e.g. Cd, Pb, Cr, Zn, Cu and Ca) in the urbanized area were higher than their corresponding concentrations in global average soil and soil in un-urbanized areas outside the urbanized area. Metal contents in soil were very high in densely populated districts and around some industrial facilities. The only exception was Pb distribution, which was more dispersed, due to the nature of motor vehicle emissions. Alteration of the Cd, Zn, Cu and Cr content of soil was confined to the inhabited and industrial areas, whereas enrichment factors of these elements were close to unity in the remaining study area. Factor analysis identified two polluted soil factor associations. One factor includes elements, such as Zn and Cd, which had high factor scores in inhabited areas and the other factor (high loading of Pb) represents soil polluted by motor vehicle emissions.
