METHODS: In order to distinguish between topical and systemic absorption in the eye, we applied 0.5% dexamethasone-cyclodextrin eyedrops to one (study) eye of rabbits and not to the contralateral (control) eye. Drug levels were measured in each eye. The study eye showed the result of the combination of topical and systemic absorption, whereas the control eye showed the result of systemic absorption only. Systemic absorption was also examined after intranasal and intravenous administration of the same dose of dexamethasone. RESULTS: In the aqueous humour dexamethasone levels were 170 +/- 76 ng/g (mean +/- standard deviation) in the study eye and 6 +/- 2 ng/g in the control eye. Similar ratios were seen in the iris and ciliary body. In the retina the dexamethasone level was 33 +/- 7 ng/g in the study eye and 14 +/- 3 ng/g in the control eye. Similar ratios were seen in the vitreous humour. Systemic absorption was similar from ocular, intranasal and intravenous administration. CONCLUSIONS: Absorption after topical application dominates in the anterior segment. Topical absorption also plays a significant role in delivering dexamethasone to the posterior segment of the rabbit eye. In medication administered to the retina, 40% of the drug reaches the retina via the systemic route and 60% via topical penetration. Dexamethasone-cyclodextrin eyedrops deliver a significant amount of drug to the rabbit retina

The impact of nursing education and job characteristics on nurse's perceptions of their family nursing practice skills.

However, little is known about the impact of graduate school education as well as continuing education in family systems nursing (FSN) on nurses' perceptions of their family nursing practice. To evaluate the level of nursing education, having taken a continuing hospital educational course in family system nursing (FN-ETI programme), and the impact of job characteristics on nurses' perceptions of their family nursing practice skills. Participants were 436 nurses with either a BSc degree or graduate degree in nursing. The Job Demand, Control and Support model guided the study (R. Karasek and T. Theorell, 1992, Healthy Work: Stress, Productivity, and the Reconstruction of Working Life, Basic Books, New York, NY). Scores for the characteristics of job demands and job control were created to categorise participants into four job types: high strain (high demand, low control), passive (low demand, low control), low strain (low demand, high control) and active (high demand, high control). Nurses with a graduate education who had taken the FN-ETI programme scored significantly higher on the Family Nursing Practice Scale than nurses with an undergraduate education. Nurses who were characterised as low strain or active scored significantly higher on the Family Nursing Practice Scale than the nurses who were characterised as high strain. Further, the interaction of education by job type was significant regarding family nursing practice skills. Hierarchical regression revealed 25% of the variance in family nursing practice skills was explained by job control, family policy on the unit, graduate education and employment on the following divisions: Maternal-Child, Emergency, Mental Health or Internal Medicine.Research Fund of the Landspitali the University Hospital in Iceland Science Fund of the Icelandic Nurse Association Research Fund at the University of Icelan

The Impact of Family Strengths Oriented Therapeutic Conversations on Parents of Children with a New Chronic Illness Diagnosis.

To access publisher's full text version of this article click on the hyperlink belowA growing number of families with children are dealing with a new diagnosis of chronic illnesses or health problems that are demanding. Nurses are in a prime position to provide support and empowerment to these families. The aim of the study was to evaluate the benefits of two sessions of a Family Strengths Oriented Therapeutic Conversation (FAM-SOTC) intervention, offered by advanced practice nurses (APNs) to mothers (N = 31) of children and adolescents in Iceland with newly diagnosed chronic illnesses/disorders. Families of children with Juvenile Idiopathic Arthritis (JIA), epilepsy, Type 1 diabetes (T1DM), or with sleep disturbance with attention-deficit/hyperactivity disorder (ADHD), reported significantly higher family support, greater conviction about their illness beliefs, increased quality of life, and greater satisfaction with health care services after receiving two sessions of the FAM-SOTC intervention (Time 2) compared to before the intervention (Time 1). The findings emphasize the importance of the APN's role and family nursing expertise in supporting families of children with a new diagnosis of chronic illnesses or disorders who are in active treatment.Scientific Fund at Landspitali University Hospital Scientific Fund from the Icelandic Nursing Associatio

Multiple sclerosis and brief moderate exercise. A randomised study.

To access publisher full text version of this article. Please click on the hyperlink in Additional Link fieldThis is a randomised control study, to determine the effect of aerobic and strength exercise on physical fitness and quality of life in patients with mild multiple sclerosis (MS). Sixteen outpatients with definitive MS, aged 18-50, with an Expanded Disability Status Scale (EDSS) <4, completed the study. Every patient was evaluated according to physical fitness with peak oxygen consumption (V'O(2peak) ), workload and anaerobic threshold; quality of life (SF-36); and degree of disability (EDSS). The patients were then randomised to an exercise group (EG) (n =6) or a control group (CG) (n = 10). The EG exercised three times a week for five weeks, and the CG did not change their habits regarding exercise.In the EG, the mean change in workload was 0.34 W/kg (95% confidence interval (CI): 0.09-0.58), the mean change in V'O(2peak) was 4.54 mL/kg per minute (95% CI: 1.65-7.44), and the mean change in anaerobic threshold was 0.32 L/min (95% CI: 0.08-0.57). There was a tendency towards improved quality of life, and no change was detected in the degree of disability. This study confirms that brief, moderate, aerobic exercise improves physical fitness in individuals with mild MS. No evidence was found for worsening of MS symptoms in association with exercises.
