Effect of combined care nursing on patient satisfaction, staff satisfaction, and quality of care /

This research evaluates the effect of combined care nursing on three outcomes: i) patient satisfaction; ii) staff satisfaction; and iii) quality of care. Oakville-Trafalgar Memorial Hospital was in the early planning stages of changing to combined care nursing from the traditional method of providing separate postpartum and nursery care to mothers and babies. The opportunity existed to evaluate formally the change to combined care. There were three hypotheses to be investigated. Data were collected from four sources: patient surveys, staff surveys, informal interviews, and internal hospital documents. Both quantitative and qualitative data were analyzed. The surveys were administered on three different occasions to patients and staff. Other sources of data included informal interviews with patients and staff who responded to the surveys, and chart audits.The study findings revealed that the majority of respondents had increased levels of satisfaction and perceptions of increased quality of care following implementation of combined care. These findings, related to combined care and the role of change in its implementation and evaluation, indicate that there are no right or easy answers about how to make new ideas become reality in a smooth, pleasant way.

Factors affecting DNA uptake by mammalian cells

The ability to introduce DNA and express custom DNA sequences in bacteria opened the door for improvements in a large number of fields including agriculture, pharmacology, medicine, nutrition, etc. The ability to introduce foreign DNA sequences into mammalian cells in an efficient manner would have a large impact on therapeutic applications especially gene therapy. The methods in use today suffer from low efficiencies and sometimes toxicity. In this work a number of factors were evaluated for their effect onONA uptake efficiency. The factors studied included exposure to sublethal concentration of hydrogen peroxide which have been show to lead to destabilisation ofthe lysosomes. These exposures have proven to be very toxic to cells when combined with either the calcium phosphate or the lipofectAMINE® transfection methods. Another factor evaluated was exposure to Electro-Magnetic Fields (EMF). This was fuelled by the fact that EMF have been shown to mediate a number of effects on cell structure and/or physiology. EMF exposure by itself was not sufficient to induce the cells to pick up the DNA, therefore its effect on calcium phosphate and lipofectAMINE® was tested. Although some positive results were obtained, the variability of these results exceeded by far any observed enhancements which discouraged any further work on EMF. Also tested was the possible effect the presence of the cytomegalovirus (CMV) sequence might have on DNA uptake (based on previous results in this lab). It was found that the presence ofCMV in the DNA sequence does not enhance uptake or slow down degradation of the internalised DNA. The final factor tested was the effect of basic amino acids on transfection efficiency. It was found that arginine can enhance DNA uptake by about 170% v/ith calcium phosphate and about 200% with LipofectAMINE®. A model was proposed to explain the effect of arginine as well as the lack of effect from other amino acids.

Effect of increased milk intake combined with endurance exercise training on body composition, blood-lipids and inflammatory markers in overweight young males

Consuming low-fat milk (LFM) after resistance training leads to improvements in body composition. Habitual aerobic exercise and dairy intake are relatively easy lifestyle modifications that could benefit a population at risk for becoming obese. Thus, the purpose of this study was to investigate combining increased LFM intake with endurance exercise on body composition, blood-lipid profile and metabolic markers. 40 young males were randomized into four groups: one ingesting 750mL LFM immediately post-exercise, the other 6hrs post-exercise; and two isocaloric carbohydrate groups ingesting at the two different times. Participants completed a 12 week endurance-training program (cycling 1 hour/day at ~60%VO2peak, 5 days/week). 23 participants completed the study. Increases in lean mass (p < 0.05), and decreases in anti-inflammatory marker adiponectin (p < 0.05) were seen in all groups. No other significant changes were observed. Future analyses should focus on longer duration exercise and include a larger sample.
