Undergraduate nursing students' health promotion counselling self-efficacy

In this study, undergraduate nursing students' self-efficacy for carrying out health promotion activities with clients in nursing settings was examined Students in the first, second and fourth year of a baccalaureate programme felt moderately efficacious about their knowledge and abilities for health promotion counselling in the three content domains measured (smoking cessation, nutrition and exercise) Senior nursing students had the highest self-efficacy scores, suggesting a positive impact on health promotion skills over the educational experience In all areas of health promotion, regardless of year in then: educational programme, students reported significantly lower efficacy for their ability to engage clients in an educational programme for behavioural change Educational directions from Bandura's theory are described     

A pilot study of a parent-education group for families affected by depression.

OBJECTIVE: This study assessed the feasibility and efficacy of a parent-education group for families with young children and a parent with depression. We designed the program to be readily disseminated if shown to be effective. METHOD: We recruited 44 parents with depression from clinics and family doctors in Hamilton, Ontario, and randomly assigned them to receive the parenting program or to a wait-list control group. The outcomes measured included knowledge of depression, parenting, family relationships, depression symptoms, child depressive symptoms, and functioning. We used analysis of covariance to test for posttreatment differences between experimental and control groups. RESULTS: Of the treatment group, 27% dropped out at posttreatment, and 43% by follow-up. Those who dropped out had more severe depression at baseline than did those who completed the program, and there was selective loss of parents with more severe depression in the experimental group. In intention-to-treat analyses at posttreatment, probands in the experimental group reported more improvements on family functioning, parenting sense of competence, and family and parent conflict than did control subjects. Standardized effect sizes (ES) were medium (0.4 to 0.6). When baseline depressive symptom scores were controlled in the analyses, the between-group differences were reduced, showing that selective loss of participants may have influenced the findings. CONCLUSIONS: On balance, the results are encouraging and support the further development and evaluation of the group intervention. However, the study does not provide unequivocal evidence in support of the program. Before it is transferred to other settings, the program needs further modification to improve participation by parents with more severe depression and further evaluation of its effectiveness.     

The onset of tense marking in children at risk for specific language impairment.

PURPOSE: The purpose of this study was to develop and evaluate measures reflecting the onset of tense marking for children between the ages of 2;0 (years;months) and 3;0. METHOD: The validity of 4 cumulative measures of tense marker emergence and productivity was evaluated relative to existing measures of early grammatical development in a sample of 20 children followed longitudinally. Fourteen children were at risk for specific language impairment (AR-SLI group), and 6 children had low average language abilities (LA group). RESULTS: All measures of onset were highly correlated with the traditional measures; however, children's progress toward mastery of grammatical tense marking was best explained by the productivity of their tense marking systems. Finally, the onset measures imposing productivity requirements best differentiated children in the LA group from those in the AR-SLI group. CONCLUSIONS: The clinical implications for using the late onset of tense marking to improve the early identification of SLI are discussed.     

Emergency Preparedness for Health Professionals in a Statewide AHEC Program: the first two years.

In 2003 through 2005, the California Statewide Area Health Education Centers (AHEC) Program developed an educational delivery system, through partnerships with six AHECs and state organizations concerned with emergency preparedness, to train for public health emergency preparedness the health professionals who practice primarily in the state's medically underserved areas. Four educational modules--General Emergency Preparedness, Bioterrorism, Chemical and Radiologic Agents, and Emerging Infections--were developed and delivered by a trained, multidisciplinary, community-based faculty. The authors discuss the organization, partnerships, curriculum, faculty, characteristics of trainees, outcomes of the program, effects for AHECs, and the evaluation used to commit the organization and program process to the intended program objectives during the two-year period. Over 9,000 health professionals attended one or more of the 462 educational presentations. Approximately one third of attendees were physicians, and 82% of the learners were from sites that typically care for the underserved. Important to the success of the program (which still continues in a revised form) were the types of partnerships, an orientation of the curriculum to all-hazards disaster preparedness, the delivery of educational sessions at clinical sites, and the increased capacities of community AHECs to facilitate continuing professional education. The challenges were the diminished role of a key partner organization, uncertainties within the funding agency, and the widespread geographic area to address.

The public health and brief interventions for excessive alcohol consumption: The british experience

Widely disseminated brief interventions against excessive drinking, as part of the new public health movement, have a potentially crucial role in reducing alcohol-related harm on a national scale. However, a number of conceptual problems and practical barriers to progress in this area can already be identified. This article focuses on the British experience of research and implementation of community-based brief interventions, which is longer than that of other countries, as a means of discussing these problems. Rather than being pessimistic about the possible impact of brief interventions, the article is based on the assumption that it is only by clearly recognizing and solving such problems that the potential of brief interventions in the alcohol field will be fully realized.     

The role of Na+/K+ ATPase activity during low flow ischemia in preventing myocardial injury: A 31P, 23Na and 87Rb NMR spectroscopic study

An increase in intracellular Na⁺ during ischaemia has been associated with myocardial injury. In this study, we determined whether inhibition of Na⁺/K⁺ ATPase activity contributes to this increase and whether Na⁺/K⁺ ATPase activity can be maintained by provision of glucose to perfused rat hearts during low flow, 0.5 ml/min, ischemia. We used ³¹P NMR spectroscopy to determine changes in myocardial energetics and intracellular and extracellular volumes. ²³Na NMR spectroscopy, with DyTTHA^3- present as a shift reagent, was used to measure changes in intracellular Na⁺ and ⁸⁷Rb NMR spectroscopy was used to estimate Na⁺/K⁺ ATPase activity from Rb⁺ influx rates, Rb⁺ being an NMR-sensitive congener of K⁺. In hearts provided with 11 mM glucose throughout ischemia, glycolysis continued and ATP was twofold higher than in hearts without glucose. In the glucose-hearts, Rb⁺ influx rate was threefold higher, intracellular Na⁺ was fivefold lower at the end of ischemia and functional recovery during reperfusion was twofold higher. We propose that continuation of glycolysis throughout low flow ischemia allowed maintenance of sufficient Na⁺/K⁺ ATPase activity to prevent the increase in intracellular Na⁺ that would otherwise have led to myocardial injury.     

Comparison of the morphology of three coronaviruses

Summary The morphology of three coronaviruses; avian infectious bronchitis virus strain Connecticut (IBV Conn), human coronavirus strain 229E (HCV 229E) and mouse hepatitis virus strain 3 (MHV3), were examined by negative staining. Significant differences were found in the sizes of the three coronaviruses. Furthermore, three types of surface projection of the same lengths, but varying widths and morphology, were observed. Both IBV Conn and HCV 229E had bulbous projections characteristic of coronaviruses, although the projections of HCV 229E were somewhat thinner than those of IBV Conn. On the other hand, MHV3 particles had thin, cone-shaped surface projections, that were completely unlike typical coronavirus projections. The significance of these results is discussed.With 3 Figures
