In-hand manipulation in young children: rotation of an object in the fingers.

OBJECTIVE: The purpose of this study was to look at the development of two in-hand skills of rotation. Three questions were asked: (a) Do boys' and girls' performance differ significantly? (b) Does performance improve with age? and (c) Can periods of rapid improvement with age be seen on the tasks presented? METHOD: The in-hand manipulation skill of rotation was measured in 154 right-handed children between the ages of 3-0 years and 6-11 years as well as in 13 adults. The participants were videotaped as they either turned over small pegs in a pegboard or rotated a peg in their fingertips. The number of pegs dropped when turning and placing them back in the board, the number of times a peg could be rotated in the fingertips, the time it took to complete each task, and the methods participate used to accomplish the two tasks were recorded from the videotapes. RESULTS: The results indicated no differences between the performance of boys and girls on any of the variables studied, but performance did change with age, and periods of rapid change were identified. Further, when compared on methods used, the children did not achieve the same speed or consistency as the adult participants. CONCLUSION: The development of in-hand manipulation skills of rotation involves improvement in the dimension of speed, method, and consistency. Observation of these skills in a child can add to a therapist's understanding of the child's fine motor abilities. The variability in children's performance needs to be considered in both evaluation and treatment planning.

The relationship between the Evaluation Tool of Children's Handwriting and teachers' perceptions of handwriting legibility.

OBJECTIVE: The purpose of this study was to investigate the relationship between the Evaluation Tool of Children's Handwriting (ETCH) and teachers perception of handwriting legibility METHODS: The ETCH was administered to 45 first-grade students with illegible handwriting as reported by their teachers. The teachers completed a teachers questionnaire at the same time to indicate the children's level of handwriting difficulties both in general and in specific tasks that resemble the test tasks of the ETCH. RESULTS: There was no significant relationship between the ETCH scores and the teacher questionnaire scores in either general legibility or task-specific legibility. CONCLUSION: The ecological validity of the ETCH, in reference to the teachers' perception of handwriting legibility, was not established. Further changes for scoring criteria may be warranted before the ETCH can be used with confidence that the scores obtained are meaningfully related to actual performance in the classroom as determined by teachers.

Algorithmic nursing protocol to provide optimum care post combined kidney/pancreas transplantation.

This paper explains the development of protocols to aid in the care of patients following a combined kidney/pancreas transplant. With adequate planning of care, medical and nursing problems can be detected at an early stage thus ensuring immediate and appropriated action. We have found protocols to be invaluable in the care of these patients and the one which we developed on fluids and electrolytes is outlined in this paper.

Development of a research committee at a community hospital.

This paper describes the process undertaken in setting up a nursing research committee in a community hospital in British Columbia. The primary goal of the committee is to increase awareness among bedside nurses of the value of research in their practice. This goal is based on the belief that research conducted by practicing nurses validates existing practice and promotes quality patient care, important concerns for nurse administrators.

The effects of gender and type of diabetes on HDL-cholesterol.

OBJECTIVE: To investigate the influence of gender and type of Diabetes on plasma lipoproteins and post-heparin plasma lipoprotein lipase and hepatic lipase activities. DESIGN AND PATIENTS: Cross sectional study of 22 lean Type 2 diabetic subjects (11 men, 11 women) individually matched for gender, BMI and HbA1 with 22 Type 1 (C-peptide negative) diabetic subjects. MEASUREMENTS: Samples were taken for fasting lipids and post heparin samples were obtained for estimation of post heparin lipolytic activity. RESULTS: In men, HDL-Cholesterol was higher in Type 1 diabetes [1.56 (range 0.97-2.27) vs 1.07 (0.54-1.78) mmol/l, p = 0.009] and this was reflected in both HDL2-cholesterol [0.42 (0.02-1.36) vs 0.22 (0.01-0.90) mmol/l, p = 0.05] and HDL3-cholesterol [1.00 (0.75-1.51) vs 0.72 (0.53-0.87) mmol/l, p = 0.02] subfractions while serum triglyceride concentrations were similar. Lipoprotein lipase activity was higher in men with Type 1 diabetes [16.2 (6.2-42.4) vs 9.77 (5.6-22.6) mmol/h/l, p = 0.02] while hepatic lipase activities were similar [15.7 (9.3-23.0) vs 14.0 (6.8-24.0) mmol/h/l, NS). In women, there were no significant differences between Type 1 and Type 2 diabetes in triglycerides, HDL-C, HDL2 or HDL3. Lipoprotein lipase activity was higher in Type 1 women [19.3 (14.1-35.7) vs 11.0 (7.2-15.2) mmol/h-1 1-1, p = 0.0006] but lipatic lipase activity was also higher [12.1 (4.8-20.5) vs 7.3 (2.3-21.4) mmol/h-1 1-1, p = 0.023]. CONCLUSION: In non-obese diabetic subjects, men with Type 1 diabetes have higher HDL-cholesterol than those with Type 2 diabetes, possibly due to the action of peripheral insulin on lipoprotein lipase activity, while in women, HDL-cholesterol concentrations were similar in Type 1 and Type 2 subjects possibly because of lowered lipatic lipase activity in Type 2 women which offsets the increased lipoprotein lipase activity of the Type 1 women.

Endothelium, for example.

Endothelial nitric oxide production contributes at many levels to cardiovascular efficiency (considered as tissue perfusion relative to cardiac work). Endothelial dysfunction is found in many conditions, including all known risk factors for atheroma, and is usually generalised, when present, involving microvessels as well as large arteries, impairing cardiovascular efficiency and potentially initiating atheroma. Loss of flow-related dilation is a manifestation of endothelial dysfunction and can be measured non-invasively, thereby providing a potential marker of reversible atherogenic susceptibility.
