The sensory acceptance of fibre-enriched cereal foods:a meta-analysis

Improved understanding of the sensory responses to fibre fortification may assist manufacturers and health promotion efforts. The effects of fibre fortification (or modified ingredients) on sensory acceptability of baked cereal foods (bread, cookies, muffins) were estimated by linear random-effects meta-analysis of twenty eligible studies (869 panellists, 34% male). As little as 2 g per 100 g fortification caused moderate–large reductions in overall acceptability, flavour acceptability, and appearance acceptability in most items, with cookies most negatively affected. Fortification of base nonfortified foods with low initial acceptability improved acceptability; however, at higher basic levels, fortification lowered acceptability. Fortification improved texture acceptability of muffins and bread with low base acceptability, but lowered texture acceptability when base acceptability was high. Flavour improvement of muffins with fortification decreased with increasing base food acceptability. Fibre fortification of baked cereal foods lowers acceptability, but food format and base food acceptability affect the magnitude and direction of responses. Refining fibre fortification approaches could improve consumer uptake

Dimensions of oral health related quality of life measured by EQ-5D+ and OHIP-14

BACKGROUND: The aims of the study were to compare the dimensions of oral-health-related quality-of-life measured by a generic health state measure, the EuroQol, and a specific oral health measure, the Oral Health Impact Profile. METHODS: Data were collected in 2001–02 from a random sample of South Australian dentists using mailed self-complete questionnaires. Dentists recorded the diagnosis of dental problems and provided patients with self-complete questionnaires to record the nature, severity and duration of symptoms using the EuroQol (EQ-5D+) and 14-item version of the Oral Health Impact Profile (OHIP-14) instruments. RESULTS: Data were available from 375 patients (response rate = 72%). The EuroQol items of mobility, self care and usual activities formed a separate cluster of variables, as did anxiety/depression and cognition, while pain clustered with items from the OHIP physical pain subscale. OHIP items tended to form clusters consistent with the subscales of social disability, physical disability, physical pain, functional limitation and psychological discomfort. The OHIP handicap items clustered between the OHIP social disability and physical disability subscales. The OHIP psychological disability items split between the social disability and psychological discomfort subscales. CONCLUSIONS: The observed clusters of variables empirically supported most of the conceptual dimensions of the OHIP. Both instruments covered symptom experience of pain indicating overlapping domains. However there was partial separation of the generic and specific items, EuroQol covered daily activities such as self-care and usual activities and OHIP covered oral health-specific aspects of functional limitation and physical disability as well as psychological and social aspects of disability and handicap

The Effect of the Form of Tax Incentives on Individuals’ Savings Decisions

Congress and the media have both expressed concerns about Americans’ low savings rates. We address these concerns by investigating the extent to which the form of an investment’s tax preference affects individuals’ willingness to choose a tax-preferred vehicle over a less restrictive, but non-tax-preferred, investment. Specifically, we tested the extent to which subjects chose a traditional savings plan versus an investment resembling either a traditional IRA, Roth IRA, or government matching program. We find that subjects are not as sensitive to the form of the tax preference as they are to restrictions on their ability to withdraw funds. This suggests that, by reconsidering the extent to which individuals are forced to trade off tax savings and liquidity restrictions, Congress might more effectively promote individuals’ retirement savings

Oral Health in South Australia - 2008

Oral health in South Australia 2008 provides a comprehensive summary of the oral health of South Australian residents. This publication was developed from a range of surveys conducted by the Australian Research Centre for Population Oral Health (ARCPOH) and administrative data provided by state dental services. Information provided in this publication includes data on caries experience and periodontal diseases of children and adults, tooth retention and loss among adults, access to dental care, cost of dental care and the dental labour force. Information on the oral health of Indigenous children and adults is also provided. The publication highlights the recent increase in the level of dental decay among primary and secondary school children, the low percentage of school aged children visiting the school dental service, the extent of individual out-of-pocket expenditure on dental services, and issues with access to dentists and dental hygienists outside of the Adelaide metropolitan area

Oral health of people with physical and intellectual disabilities: Training carers of people with physical and intellectual disabilities

This study aimed to benefit the oral health and OHRQoL of two groups of people with special needs: ‘care recipients’ (directly and via their carers) and ‘employees’. The study aims reflect the different approaches used. For carers and care recipients, To provide a home-based intervention, training carers in providing improved oral care for adults with disabilities To evaluate the intervention by, Assessing the change in carer psychosocial factors pre- to post-training Benchmarking to a dentist the oral health assessment of carers post-training For employees, To provide a workplace intervention combining oral health education and timely referral for treatment To evaluate the intervention by assessing change in self-rated oral health, OHRQoL and oral health behaviours pre- and post-intervention.The research reported in this paper is a project of the Australian Primary Health Care Research Institute which is supported by a grant from the Australian Government Department of Health and Ageing under the Primary Health Care Research Evaluation and Development Strategy

Understanding barriers and facilitators of access to dental care and completion of treatment for Aboriginal adults

This study aimed to understand why some Aboriginal adults who are referred for dental care do not take up or complete a recommended course of dental care. The study Explored why some Aboriginal adults take up a course of care after being referred and the perceived enabling and disabling factors and attitudes around beginning and completing a course of dental care. Has the potential to improve the practices of staff of the SA Dental Service in supporting Aboriginal clients in accessing dental care. It could also improve the communication about dental care available to Aboriginal people and thus improve their oral health and access.The research reported in this paper is a project of the Australian Primary Health Care Research Institute which is supported by a grant from the Australian Government Department of Health and Ageing under the Primary Health Care Research Evaluation and Development Strategy

The economic implications of HLA matching in cadaveric renal transplantation.

Abstract Background: The potential economic effects of the allocation of cadaveric kidneys on the basis of tissue-matching criteria are controversial. We analyzed the economic costs associated with the transplantation of cadaveric kidneys with various numbers of HLA mismatches and examined the potential economic benefits of a local, as compared with a national, system designed to minimize HLA mismatches between donor and recipient in first cadaveric renal transplantations. Methods: All data were supplied by the U.S. Renal Data System. Data on all payments made by Medicare from 1991 through 1997 for the care of recipients of a first cadaveric renal transplant were analyzed according to the number of HLA-A, B, and DR mismatches between donor and recipient and the duration of cold ischemia before transplantation. Results: Average Medicare payments for renal-transplant recipients in the three years after transplantation increased from $60,436 per patient for fully HLA-matched kidneys (those with no HLA-A, B, or DR mismatches) to$80,807 for kidneys with six HLA mismatches between donor and recipient, a difference of 34 percent (P\u3c0.001). By three years after transplantation, the average Medicare payments were $64,119 for transplantations of kidneys with less than 12 hours of cold-ischemia time and$74,997 for those with more than 36 hours (P\u3c0.001). In simulations, the assignment of cadaveric kidneys to recipients by a method that minimized HLA mismatching within a local geographic area (i.e., within one of the approximately 50 organ-procurement organizations, which cover widely varying geographic areas) produced the largest cost savings ($4,290 per patient over a period of three years) and the largest improvements in the graft-survival rate (2.3 percent) when the potential costs of longer cold-ischemia time were considered. Conclusions: Transplantation of better-matched cadaveric kidneys could have substantial economic advantages. In our simulations, HLA-based allocation of kidneys at the local level produced the largest estimated cost savings, when the duration of cold ischemia was taken into account. No additional savings were estimated to result from a national allocation program, because the additional costs of longer cold-ischemia time were greater than the advantages of optimizing HLA matching

Positive and negative affect and oral health-related quality of life

BACKGROUND: The aims of the study were to assess the impact of both positive (PA) and negative affect (NA) on self-reported oral health-related quality of life and to determine the effect of including affectivity on the relationship between oral health-related quality of life and a set of explanatory variables consisting of oral health status, socio-economic status and dental visiting pattern. METHODS: A random sample of 45–54 year-olds from metropolitan Adelaide, South Australia was surveyed by mailed self-complete questionnaire during 2004–05 with up to four follow-up mailings of the questionnaire to non-respondents (n = 986 responded, response rate = 44.4%). Oral health-related quality of life was measured using OHIP-14 and affectivity using the Bradburn scale. Using OHIP-14 and subscales as the dependent variables, regression models were constructed first using oral health status, socio-economic characteristics and dental visit pattern and then adding PA and NA as independent variables, with nested models tested for change in R-squared values. RESULTS: PA and NA exhibited a negative correlation of -0.49 (P < 0.01). NA accounted for a larger percentage of variance in OHIP-14 scores (3.0% to 7.3%) than PA (1.4% to 4.6%). In models that included both PA and NA, PA accounted for 0.2% to 1.1% of variance in OHIP-14 scores compared to 1.8% to 3.9% for NA. CONCLUSION: PA and NA both accounted for additional variance in quality of life scores, but did not substantially diminish the effect of established explanatory variables such as oral health status, socio-economic status and dental visit patterns
