PAIN MEDICINE, Issue 2 2000

Authors: DA Fishbain, University of Miami School of Medicine; RB Cutler; HL Rosomoff, University of Miami School of Medicine; T. Khalil, University of Miami Comprehensive Pain and Rehabilitation Center at South Shore Hospital; R. Steele-Rosomoff, University of Miami School of Medicine Objective: To examine the impact of preinjury job perceptions on chronic pain patients' (CPPs) return to work after pain facility treatment. Design: A total of 128 CPPs completed a series or rating scales and yes/no questions relating to their preinjury job perceptions and a question relating to intent to return to the same type of preinjury job following pain facility treatment. These CPPs were part of a grant study for prediction of return to work, and therefore their work status was determined at 1, 3, 6, 12, 18, 24, and 30 months after treatment. The preinjury job perceptions and other demographic variables were used to predict return to work. Stepwise discriminant analysis was used to predict return to work at the 1-month and final time points utilizing the above variables. Stepwise regression analysis was used to predict mean employment status (at all time points), also using the above variables. Results: For the 1-month time point, employment status was predicted by intent, educational status, work dangerous perception complaint, job stress, job physical demands, job liking, and job role conflicts. Here, 79.49% of the CPPs were correctly classified. For the final time point, employment status was predicted by the first 3 predictors for the 1-month time point (in the same order), and age, job stress, and gender. Here, 74.58% of the CPPs were correctly classified. Mean employment status was predicted by intent and educational status. Conclusions: There is a relationship between preinjury job perceptions and actual return to work after pain facility treatment. Voiced intent not to return to the preinjury type of job is highly predictive of not returning to work after pain facility treatment. [source]

Implications of Components of Income Excluded from Pro Forma Earnings for Future Profitability and Equity Valuation

Wayne R. Landsman
Abstract:, This study addresses three research questions relating to total exclusions, special items, and other exclusions. Are each of these pro forma exclusion components forecasting irrelevant? Are each of the exclusion components value irrelevant? Are the valuation multiples on the exclusion components justified by their ability to forecast future profitability as predicted by the Ohlson (1999) model? Findings are generally consistent with the market-inefficiency results presented in Doyle et al. (2003). Total exclusions are valued negatively by the market despite the prediction that total exclusions will be valued positively. Valuation results also suggest that stocks with positive other exclusions are overpriced. [source]

Costs of accessing surgical specialists by rural and remote residents

Sarah L. Rankin
Introduction: Access to surgical specialist services by rural and remote residents in Australia is limited. Little information is available on the cost to rural residents of accessing specialist treatment. The aim of the present study was to define the personal costs incurred by country patients in Western Australia when accessing specialist surgical services in a rural or metropolitan setting. Methods: A random sample of 50 patients who attended a visiting rural surgical service between December 1998 and February 1999 inclusive was recruited. In a structured telephone interview patients were asked 40 non-clinical questions relating to their recent specialist consultation. The cost of accessing these services was determined from time lost from work, distance and travel expenses. The same formula was then applied to estimate the cost of attending a base metropolitan hospital. The need for an accompanying person was determined from a subset of 16 patients who had transferred to metropolitan specialist consultation in the previous 12 months. Average waiting list times for consultations and common surgical procedures for the visiting service were compared with those for a metropolitan-based service. Results: An estimated saving of AU$1077 was made per specialist consultation when accessing a local rather than a metropolitan service. Savings were observed in travel time, distance travelled, lost income, provision of an escort and waiting time. Conclusion: The present study shows that the personal costs and difficulties incurred by rural and remote residents when accessing specialist treatment can be reduced if a visiting specialist service is available.

Cooperation and conflict in host,microbe relations

APMIS, Issue 5-6 2009
Hosts and microbes associate in a variety of relations along a continuum ranging from symbiotic to pathogenic. Defence mechanisms have been evolutionarily selected in both hosts and microbes to protect the organism's integrity. Such defences have to be utilized with caution. They must be adapted to the tasks at hand; otherwise any symbiotic relation would be impossible. To explain this cautionary use of defences we need to understand how life on Earth evolved into cooperative and competing entities at various levels of organization. The purpose of this article is to review theory and selected mechanisms relating to the evolution and development of host,microbe interactions, with special emphasis on host responses. The rationale is that without theory, extrapolations from misleading observations can dominate and distort, for a significant time, the course of a scientific field. The argument is set forth that social evolution theory provides a conceptual framework for addressing questions relating to interaction between hosts and microbes. The article is a partial summary of arguments presented in my book Defending life , the nature of host,parasite relations. [source]

Maternal cultural participation and child health status in a Middle Eastern context: evidence from an urban health study

M. Khawaja
Abstract Background, The negative effect of poverty on child health has been well established. However, rapid urbanization in developing countries prompts new research questions relating to socio-cultural practices and other related variables in these settings. Objective, To examine the association between maternal cultural participation and child health status in impoverished neighbourhoods of Beirut, Lebanon. Methods, A cross-sectional survey of 1241 mothers with children aged less than 5 years was conducted from randomly selected households in three impoverished neighbourhoods of diverse ethnic and religious make-up. The outcome variable was child health status (good/bad) as assessed by the mother. Maternal variables, including cultural participation, education, demographic and environmental/structural factors, were studied. Descriptive statistics and bivariate associations were provided using Pearson's chi-square tests. Unadjusted and adjusted odds ratios were then obtained from binary logistic regression models. Results, Two indicators of maternal cultural participation, namely watching entertaining television and attending movies/art exhibitions, were found to be significantly associated with child health status after controlling for other risk factors. The quality of water, the quality of local health services and maternal education were also significantly associated with child health status. Household income, child gender and household dampness had no significant association with child health status in this context. Conclusion, Maternal cultural participation was a significant predictor of child health status in impoverished urban communities. Improving child health through culturally focused interventions for mothers, especially in deprived areas, may be greatly important. [source]
