NB housing study protocol: investigating the relationship between subsidized housing, mental health, physical health and healthcare use in New Brunswick, Canada.

BACKGROUND: Income and housing are pervasive social determinants of health. Subsidized housing is a prominent affordability mechanism in Canada; however, waitlists are lengthy. Subsidized rents should provide greater access to residual income, which may theoretically improve health outcomes. However, little is known about the health of tenants who wait for and receive subsidized housing. This is especially problematic for New Brunswick, a Canadian province with low population density, whose inhabitants experience income inequality, social exclusion, and challenges with healthcare access.  METHODS: This study will use a longitudinal, prospective matched cohort design. All 4,750 households on New Brunswick's subsidized housing wait list will be approached to participate. The survey measures various demographic, social and health indicators at six-month intervals for up to 18 months as they wait for subsidized housing. Those who receive housing will join an intervention group and receive surveys for an additional 18 months post-move date. With consent, participants will have their data linked to a provincial administrative database of medical records.  DISCUSSION: Knowledge of housing and health is sparse in Canada. This study will provide stakeholders with a wealth of health information on a population that is historically under-researched and underserved.

Implicit personality theory in evaluation of brand extensions.

Transference, the extent to which consumers transfer their opinions of a parent brand to a new extension, is critical to the success of any brand-extension strategy. Past research has shown that transference is a complex process that varies among persons depending upon an implicit personality theory, entity versus incremental. In a laboratory experiment analysis of ratings for 100 21-yr.-old undergraduates of attitude, perceived fit and risk, prior product involvement, and implicit personality theory (entity versus incremental) the influence of consumers' implicit personality theory on transference was considered within the brand-extension context. As expected, the amount of transference differed between those espousing entity and incremental theories. "Entity theorists" were much more likely to transfer feelings associated with the parent brand to the new extension than were "incremental theorists" who did not rely on prior brand information when forming evaluations of a new extension. This effect did not occur when perceived fit between the parent brand and the extension was high.

The salvage of open grade IIIB ankle and talus fractures.

Between 1983 and 1989, 11 open grade IIIB ankle or talus fractures were treated according to protocol including debridement, temporary placement of antibiotic beads, soft tissue coverage (including seven free vascular tissue transfers), intravenous antibiotics and fusion using an anterior plate, and bone graft. All patients had a minimum of three separate hospitalizations. Each had at least five operative procedures performed with an average of 8.2/patient (range: 5-12). The total in-patient hospital stay averaged 61.6 days (20-107 days) and in patient costs averaged $62,174.43/patient (range: $33,535.06-$143,847.45). Overall hospital cost averaged $1,009.32/day. Follow-up averaged 47.8 months (range 32-85 months), with an average time to union of 4.4 months. Fusion rate and muscle flap success was 100%. Although fusion and eradication of infection in this specific group of patients was possible, significant functional and psychosocial disability remained. Eight of eleven patients had significant pain, difficulty with stairs, and limited ambulation. All changed jobs or were unemployed. Patients with open grade IIIB tibiotalar injuries with significant bone loss may therefore benefit from early amputation. A multicenter randomized clinical outcome study is needed.

Use of angiographic needles with or without stylets: pathologic assessment of vessel walls after puncture.

There is controversy as to whether angiographic needles without stylets produce more arterial damage than those with stylets. Iliac arteries from 15 fresh human cadavers were punctured 56 times with either an 18-gauge angiographic needle with a stylet or one without a stylet (28 punctures with each needle type). These puncture sites were serially sectioned and examined microscopically. Each needle tract was evaluated for margin irregularity, shape of puncture, and approximation of edges. No statistically significant differences in arterial wall changes were found. The authors' data suggest that the choice of beveled needle use in angiography can probably be made on a basis other than concern for differences in vessel wall damage secondary to the presence or absence of a stylet.

Office organization and experiences with hearing aid dispensing.

Roles of the otolaryngologist and the audiologist in providing hearing health care are expanding as a result of current trends in amplification technology, legislation, and patient populations. Within clinic dispensing of hearing aids has become a part of this role expansion. Requirements for setting up a dispensary, fitting procedures, fee analysis, and statistical results of 4 1/2 years' experience are discussed. On the basis of the benefits described, direct dispensing is advocated.
