- Background: Aerobic fitness is of great value for reducing risk of mortality and cardiovascular diseases. Objective: This study evaluated the performance in and correlations between a new test (five-minute pyramid test, 5MPT), the six-minute walk-test (6MWT) and maximal oxygen uptake (VO(2max)) among old and young adults. Methods: Forty-four habitually active adults (females and males), 23 old (64-79 years) and 21 young (20-32 years) participated. In the 5MPT, the participants moved back and forth along a short walkway (5.5 m) over boxes (height: 'old people' 0.42 m, 'young people' 0.62 m) arranged like an elongated step pyramid for 5 min. Power in the pyramid test (5MPT(power)) was calculated as the product of numbers of laps, body weight, gravity and highest box level divided by time. A 6MWT and a maximal cycle ergometer test for direct measurements of VO(2max) were also performed. In all tests heart rate, with on-line electrocardiography, and perceived exertion were recorded. Results: There was a strong correlation between the 5MPT(power) and VO(2max) for the entire group studied (r = 0.98), and each of the four subgroups old and young females and males separately (r = 0.78-0.98). Contrary to several earlier studies, especially involving people with various diseases, the present data showed that 6MWT cannot be used to predict VO(2max) among old females and young adults. The correlation with VO(2max) was weaker for the 6MWT than for the 5MPT(power). The relative performance values for the old compared to the young (ratio old/young × 100) were considerably lower in 5MPT(power) and VO(2max) (47-55%) than in distance and 'work' in the 6MWT (82-86%). Conclusions: The results, with age and gender variations, can be valuable information in health-fitness contexts, since measuring physical aerobic capacity is very significant in connection with risk evaluations of mortality and various diseases. The 5MPT is a rapid, functional, easy and inexpensive tool for predicting assessed maximal aerobic power.

- BACKGROUND: The aim of this study was to compare linear position transducer force plate-based methods and more complex combinations of those for calculation of power output in loaded squat jump.METHODS: Eight methods were used simultaneously in data collection: vertical ground reaction force (VGRF), ground reaction forces (GRF), 1 linear position transducer (1LPT), 1LPT and VGRF (1LPT+VGRF), 2 linear position transducers (2LPTs), 2LPTs and VGRF (2LPTs+VGRF), 5 linear position transducers (5LPTs), 5LPTs and GRF (5LPTs+GRF). Power output was calculated for each lift according to the sensor or sensors used and the results were compared.RESULTS: Power output calculated separately with LPTs and GRF method did not differ significantly from combined methods such as 1LPT+VGRF, 2LPTs+VGRF. No significant differences were found when comparing power output between 5LPTs+GRF and combined methods such as 2LPTs+VGRF.CONCLUSIONS: This study indicates that test methodology with a simple single linear position transducer setup and or force platform suffice when recording vertical jump such as loaded squat jump.

- AIMS: This paper is a report of a study examining research utilization in nursing. The specific aims were to (1) clarify the construct of research utilization, and (2) identify observable indicators of research utilization.BACKGROUND: Robust measures of research utilization do not exist despite steadily increasing numbers of studies in the field. One reason for this is theoretical confusion surrounding the central concepts in the field.METHOD: A qualitative (focus group) design was used to explore the construct of research utilization in two countries: Canada and Sweden. A systematic and sequential (three phases) approach to expert sampling framed the study. Phase 1 consisted of initial construct clarification by the research team (2005). In Phase 2, a face-to-face meeting with a panel of international research utilization nursing experts was held (2005). Phase 3 consisted of a series of focus groups with nursing care (direct and non-direct) providers (2005-2007). Data were analysed using content analysis.FINDINGS: The nursing care providers did not commonly use the term 'research utilization'. Several examples of research utilization were provided; a majority of these examples related to instrumental research utilization and became increasingly concrete as one moved from non-direct to direct care participants. Participants identified several indicators of research utilization (instrumental and conceptual). From these indicators, a measurement schematic was derived.CONCLUSIONS: The construct of research utilization is multi-faceted. Several indicators of research utilization were identified, which can be used to augment existing or develop a new and improved measure that taps both instrumental and conceptual use.

- Background: International organisations, e.g. WHO, stress the importance of competent registered nurses (RN) for the safety and quality of healthcare systems. Low competence among RNs has been shown to increase the morbidity and mortality of inpatients. Objectives: To investigate self-reported competence among nursing students on the point of graduation (NSPGs), using the Nurse Professional Competence (NPC) Scale, and to relate the findings to background factors. Methods and participants; The NPC Scale consists of 88 items within eight competence areas (CAs) and two overarching themes. Questions about socio-economic background and perceived overall quality of the degree programme were added. In total, 1086 NSPGs (mean age, 28.1[20-56] years, 87.3% women) from 11 universities/university colleges participated. Results: NSPGs reported significantly higher scores for Theme I "Patient-Related Nursing" than for Theme II "Organisation and Development of Nursing Care". Younger NSPGs (20-27 years) reported significantly higher scores for the CAs "Medical and Technical Care" and "Documentation and Information Technology". Female NSPGs scored significantly higher for "Value-Based Nursing". Those who had taken the nursing care programme at upper secondary school before the Bachelor of Science in Nursing (BSN) programme scored significantly higher on "Nursing Care", "Medical and Technical Care", "Teaching/Learning and Support", "Legislation in Nursing and Safety Planning" and on Theme I. Working extra paid hours in healthcare alongside the BSN programme contributed to significantly higher self-reported scores for four CAs and both themes. Clinical courses within the BSN programme contributed to perceived competence to a significantly higher degree than theoretical courses (932% vs 875% of NSPGs). Summary and conclusion: Mean scores reported by NSPGs were highest for the four CAs connected with patient-related nursing and lowest for CAs relating to organisation and development of nursing care. We conclude that the NPC Scale can be used to identify and measure aspects of self-reported competence among NSPGs. (C) 2015 Elsevier Ltd. All rights reserved.

- BACKGROUND: A commonly recommended strategy for increasing research use in clinical practice is to identify barriers to change and then tailor interventions to overcome the identified barriers. In nursing, the BARRIERS scale has been used extensively to identify barriers to research utilization.AIM AND OBJECTIVES: The aim of this systematic review was to examine the state of knowledge resulting from use of the BARRIERS scale and to make recommendations about future use of the scale. The following objectives were addressed: To examine how the scale has been modified, to examine its psychometric properties, to determine the main barriers (and whether they varied over time and geographic locations), and to identify associations between nurses' reported barriers and reported research use.METHODS: Medline (1991 to September 2009) and CINHAL (1991 to September 2009) were searched for published research, and ProQuest(R) digital dissertations were searched for unpublished dissertations using the BARRIERS scale. Inclusion criteria were: studies using the BARRIERS scale in its entirety and where the sample was nurses. Two authors independently assessed the study quality and extracted the data. Descriptive and inferential statistics were used.RESULTS: Sixty-three studies were included, with most using a cross-sectional design. Not one study used the scale for tailoring interventions to overcome identified barriers. The main barriers reported were related to the setting, and the presentation of research findings. Overall, identified barriers were consistent over time and across geographic locations, despite varying sample size, response rate, study setting, and assessment of study quality. Few studies reported associations between reported research use and perceptions of barriers to research utilization.CONCLUSIONS: The BARRIERS scale is a nonspecific tool for identifying general barriers to research utilization. The scale is reliable as reflected in assessments of internal consistency. The validity of the scale, however, is doubtful. There is no evidence that it is a useful tool for planning implementation interventions. We recommend that no further descriptive studies using the BARRIERS scale be undertaken. Barriers need to be measured specific to the particular context of implementation and the intended evidence to be implemented.
