Job strain predicts survey response in healthcare industry workers.

OBJECTIVES: To examine the effect of job strain on survey response. METHODS: 1,613 health care workers received a self-administered questionnaire. Thirty percent of them completed the survey on personal time without any personal monetary compensation. Working conditions were extracted by job title from the national database O*NET 6.0. Job strain was defined as the ratio of job demands to job control. Two complementary models (multi-level logistic and binomial pseudo Poisson regressions) were used to model individual survey response as a function of individual level demographic variables (age and gender), job-level socioeconomic status (SES) and job strain, and facility type (third level). RESULTS: Survey response was associated with higher SES and with less job strain. The association of SES and survey response was mediated by job strain. CONCLUSION: Employees' exposure to job strain may be an important influence on survey response, at least for workers who are not compensated for their time in completing a survey.

Evaluating students' attitudes to using PDAs in nursing clinicals at two schools.

Funding from the University of Massachusetts president's office allowed two campuses of the University of Massachusetts system to offer nursing faculty and students PDAs containing medical/nursing databases for use during their clinical rotations. A study was designed to explore student's attitudes toward the use of PDAs in a clinical setting and to determine if the manner in which the technology was introduced affected the formation of these attitudes. During the fall and spring semesters of 2005 to 2006, both sites used and evaluated the effectiveness of PDAs at the point of care, but the clinical course, faculty experience with PDAs, and method and stage of introduction varied on each campus. The University library acted as the public point of access for borrowing and technical support of the PDAs. All students were asked to complete a 21-question survey that collected quantitative and qualitative data about their attitudes toward the use of PDAs at their clinical agency. Results of questionnaires relating to students attitudes to the PDA as a learning tool showed that there were differences in the student's perceptions and acceptance of the PDA as a learning tool. The results from the analysis of the data and suggestions for the possible reasons for the differences are explored.

Inter-method agreement between O*NET and survey measures of psychosocial exposure among healthcare industry employees.

BACKGROUND: Imputed job characteristics had been used as proxy of exposure to working conditions. O*NET database provides job information that could be useful to evaluate psychosocial working conditions. METHODS: Consistency and total agreement between O*NET and self-reported psychosocial exposure (demand/control (DC), effort/reward (ER) proxy models, and emotional labor scale) were compared between healthcare specific (12 occupations, 215 workers) and other jobs (12 occupations, 146 workers). RESULTS: For dimensions of the DC and ER models, Spearman correlation and ICC coefficients were, in general, consistently high (ICC = 0.61 for decision latitude, 0.41 for rewards, 0.53 for ER ratio, and lower for others), particularly in the healthcare specific jobs. CONCLUSION: O*NET and questionnaire based psychosocial indicators showed a good job level agreement particularly on healthcare specific jobs. O*NET may be a useful source of job level psychosocial exposure, especially for the DC and ER models, for healthcare occupations within these types of facilities.

Consumption of one egg per day increases serum lutein and zeaxanthin concentrations in older adults without altering serum lipid and lipoprotein cholesterol concentrations.

Lutein and zeaxanthin accumulate in the macular pigment of the retina, and are reported to be associated with a reduced incidence of age-related macular degeneration. A rich source of lutein and zeaxanthin in the American diet is the yolk of chicken eggs. Thus, the objective of the study was to investigate the effect of consuming 1 egg/d for 5 wk on the serum concentrations of lutein, zeaxanthin, lipids, and lipoprotein cholesterol in individuals >60 y of age. In a randomized cross-over design, 33 men and women participated in the 18-wk study, which included one run-in and one washout period of no eggs prior to and between two 5-wk interventions of either consuming 1 egg or egg substitute/d. Serum lutein 26% (P < 0.001) and zeaxanthin 38% (P < 0.001) concentrations increased after 5-wk of 1 egg/d compared with the phase prior to consuming eggs. Serum concentrations of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides were not affected. These findings indicate that in older adults, 5 wk of consuming 1 egg/d significantly increases serum lutein and zeaxanthin concentrations without elevating serum lipids and lipoprotein cholesterol concentrations.

The PDA as a reference tool: libraries' role in enhancing nursing education.

"The PDA as a Reference Tool: The Libraries' Role in Enhancing Nursing Education" is a pilot project funded by the University of Massachusetts President's Office Information Technology Council through their Professional Development Grant program in 2004. The project's goal is to offer faculty and students in nursing programs at two University of Massachusetts campuses access to an array of medical reference information, such as handbooks, dictionaries, calculators, and diagnostic tools, on small handheld computers called personal digital assistants. Through exposure to the variety of information resources in this digital format, participants can discover and explore these resources at no personal financial cost. Participants borrow handhelds from the University Library's circulation desks. The libraries provide support in routine resynchronizing of handhelds to update information. This report will discuss how the projects were administered, what we learned about what did and did not work, the problems and solutions, and where we hope to go from here.

Decreased aortic early atherosclerosis and associated risk factors in hypercholesterolemic hamsters fed a high- or mid-oleic acid oil compared to a high-linoleic acid oil.

Currently, diets higher in polyunsaturated fat are believed to lower blood cholesterol concentrations, and thus reduce atherosclerosis, greater than diets containing high amounts of saturated or possibly even monounsaturated fat. The present study was designed to investigate the effect of diets containing mid- or high-linoleic oil versus the typical high-linoleic sunflower oil on LDL oxidation and the development of early atherosclerosis in a hypercholesterolemic hamster model. Animals were fed a hypercholesterolemic diet containing 10% mid-oleic sunflower oil, high-oleic olive oil, or high-linoleic sunflower oil (wt/wt) plus 0.4% cholesterol (wt/wt) for 10 weeks. After 10 weeks of dietary treatment, only the animals fed the mid-oleic sunflower oil had significant reductions in plasma LDL-C levels (-17%) compared to the high-linoleic sunflower oil group. The high-oleic olive oil-fed hamsters had significantly higher plasma triglyceride levels (+41%) compared to the high-linoleic sunflower oil-fed hamsters. The tocopherol levels in plasma LDL were significantly higher in hamsters fed the mid-oleic sunflower oil (+77%) compared to hamsters fed either the high-linoleic sunflower or high-oleic olive oil. Measurements of LDL oxidation parameters, indicated that hamsters fed the mid-oleic sunflower oil and high-oleic olive oil diets had significantly longer lag phase (+66% and +145%, respectively) and significantly lower propagation rates (-26% and -44%, respectively) and conjugated dienes formed (-17% and -25%, respectively) compared to the hamsters fed the high-linoleic sunflower oil. Relative to the high-linoleic sunflower oil, aortic cholesterol ester was reduced by -14% and -34% in the mid-oleic sunflower oil and high-oleic olive oil groups, respectively, with the latter reaching statistical significance. Although there were no significant associations between plasma lipids and lipoprotein cholesterol with aortic total cholesterol and cholesterol esters for any of the groups, the lag phase of conjugated diene formation was inversely associated with both aortic total and esterified cholesterol in the high-oleic olive oil-fed hamsters (r = -0.69, P < 0.05). The present study suggests that mid-oleic sunflower oil reduces risk factors such as lipoprotein cholesterol and oxidative stress associated with early atherosclerosis greater than the typical high-linoleic sunflower oil in hypercholesterolemic hamsters. The high-oleic olive oil not only significantly reduced oxidative stress but also reduced aortic cholesterol ester, a hallmark of early aortic atherosclerosis greater than the typical high-linoleic sunflower oil.

Antagonism of croton oil inflammation by topical emu oil in CD-1 mice.

Emu oil is derived from the emu (Dromaius novaehollandiae), which originated in Australia, and has been reported to have anti-inflammatory properties. Inflammation was induced in anesthetized CD-1 mice by applying 50 microL of 2% croton oil to the inner surface of the left ear. After 2 h, the area was treated with 5 microL of emu, fish, flaxseed, olive, or liquified chicken fat, or left untreated. Animals were euthanized at 6 h postapplication of different oils, and earplugs (EP) and plasma samples were collected. Inflammation was evaluated by change in earlobe thickness, increase in weight of EP tissue (compared to the untreated ear), and induction in cytokines interleukin (IL)-1alpha and tumor necrosis factor-alpha (TNF-alpha) in EP homogenates. Although reductions relative to control (croton oil) were noted for all treatments, auricular thickness and EP weights were significantly reduced (-72 and -71%, respectively) only in the emu oil-treated group. IL-1alpha levels in homogenates of auricular tissue were significantly reduced in the fish oil (-57%) and emu oil (-70%) groups relative to the control group. The cytokine TNF-alpha from auricular homogenates was significantly reduced in the olive oil (-52%) and emu oil (-60%) treatment groups relative to the control group. Plasma cytokine levels were not changed by croton oil treatment. Although auricular thickness and weight were significantly correlated with each other (r = 0.780, P < 0.003), auricular thickness but not weight was significantly correlated with cytokine IL-alpha (r = 0.750, P < 0.006) and TNF-alpha (r = 0.690, P < 0.02). These studies indicate that topical emu oil has anti-inflammatory properties in the CD-1 mouse that are associated with decreased auricular thickness and weight, and with the cytokines IL-1alpha and TNF-alpha.
