The Role of Reflective Activities for Occupational Therapy Education: Key Elements from a Student Perspective.

This exploratory study explored second-year students' experience with reflective activities in a Canadian Master's in Occupation Therapy program. A survey and follow-up interviews were conducted to examine multiple perspectives and the influences of reflective activities on students. Data were analyzed using descriptive statistics, Pearson Chi-Square, and thematic analysis.

Spirometric changes in normal children with upper respiratory infections.

Recent evidence that certain uncomplicated upper respiratory infections induce pulmonary function abnormalities in adults prompted a prospective study in children, in whom such infections occur more frequently. In a longitudinal study, 55 children 2.5 to 11 years of age were observed for a mean duration of 2 years.

Whole and disaturated lung phosphatidylcholine in cortisol-treated, intrauterine growth-retarded and twin control lambs at different gestational ages.

Lambs 116--124 days gestation infused in utero for 75 h with cortisol showed, when compared to twin controls, more mature lung histology and pressure-volume relationships. 32P orthophosphate incorporation into whole lung phosphatidylcholine (PC) was increased in the four cortisol-treated lambs at 116--117 days but not at 121, 123, and 124 days gestation. 14C palmitate incorporation into PC or disaturated phosphatidylcholine (DSPC) was not enhanced at 116--117 days gestation.

Cytogenetic effects of inhaled ozone in man.

Peripheral blood samples were collected from 30 normal male volunteers before and at intervals after inhaling 0.4 ppm ozone for 4 h. Data from 4 of the subjects were excluded from the analysis because of missing data points.

Estimated changes in human exposure to suspended sulfate attributable to equipping light-duty motor vehicles with oxidation catalysts.

The potential environmental impact of equipping vehicles with oxidation catalysts is estimated. Three independent techniques are used to appraise community exposures. Incremental increases in suspended sulfates and sulfuric acid aerosols are evaluated in terms of the number of vehicles equipped with oxidation catalysts.

Problem of estimating respiratory lead dose in children.

Children may be exposed to lead in their environment by a variety of mechanisms, but the final two common pathways involve ingestion and/or inhalation. The serious public health problem of overt lead intoxication from eating lead-based paint has tended to obscure low level toxicity which may be related to atmospheric lead pollution. No data exist which relate potential body burden or blood lead levels in children to ambient air lead levels.

Changes in the alveolar lining with onset of breathing.

Changes in the alveolar lining of newborns were investigated by sacrificing rabbits at birth and at intervals shortly after birth, and examining their lungs in the electron microscope. An orderly, reproducible sequence of changes in the Type II alveolar lining cells and alveolar space was demonstrated, and the observations correlated well with biochemical events. Type II cell inclusions, dense and numerous at birth, enlarged and became less dense ((1/2)-1 hour), appeared to empty their contents into the alveolar space and disappear (1(1/2) hours) and then reappeared with a mixture of sizes and densities in each cell (2 hours).
