An Interdisciplinary Clinical Advancement Program Within a Patient-Centered Care Model

Restructuring in health care does not have to compromise the pursuit of clinical excellence and quality patient care. The clinical advancement program (CAP) at the Hospital for Special Care is a newly developed multidisciplinary reward and recognition program for clinical staff. The program is integrated into the hospital's structure of service line management and, unlike traditional advancement programs, is open to all levels of care providers: professional personnel, technical staff, and aides. This article describes the basic features of the CAP model and how it was developed by a multidisciplinary task force.     

Moisturizing effect of cosmetic formulations containing Aloe vera extract in different concentrations assessed by skin bioengineering techniques

BACKGROUND/PURPOSE: The polysaccharide-rich composition of Aloe vera extracts (Aloe barbadensis Miller), often used in cosmetic formulations, may impart moisturizing properties to the product. The aim of this study was to evaluate the effect of cosmetic formulations containing different concentrations of freeze-dried Aloe vera extract on skin hydration, after a single and a 1- and 2-week period of application, by using skin bioengineering techniques. METHODS: Stable formulations containing 5% (w/w) of a trilaureth-4 phosphate-based blend were supplemented with 0.10%, 0.25% or 0.50% (w/w) of freeze-dried Aloe vera extract and applied to the volar forearm of 20 female subjects. Skin conditions in terms of the water content of the stratum corneum and of transepidermal water loss (TEWL) (Corneometer CM 825 and Tewameter TM 210) were analysed before and after a single and 1- and 2-week period of daily application. RESULTS: After a single application, only formulations supplemented with 0.25% and 0.50% (w/w) of Aloe vera extract increased the water content of the stratum corneum, while after the 2-week period application, all formulations containing the extract (0.10%, 0.25% and 0.50%) had the same effect, in both cases as compared with the vehicle. TEWL was not modified after a single and after 1- and 2-week period of application, when compared with the vehicle. CONCLUSION: Our results show that freeze-dried Aloe vera extract is a natural effective ingredient for improving skin hydration, possibly through a humectant mechanism. Consequently, it may be used in moisturizing cosmetic formulations and also as a complement in the treatment of dry skin.     

Sonography detection of small intra-abdominal fat variations.

The aim of this study was to check the reliability of sonography in measuring small variations in quantities of subcutaneous and intra-abdominal fat. Twenty-six obese women (BMI 39 +/- 6) underwent a 15 day very low calorie diet. The study included, both before and after very low calorie diet, computed tomography measurements of total (AT), visceral (VAT) and subcutaneous (SAT) adipose tissue areas, visceral/subcutaneous area ratio (V/S), waist/hip circumference ratio measurements (W/H), and ultrasound measurements of abdominal subcutaneous skin-muscle thickness, intra-abdominal muscle-aorta thickness and intra-abdominal/subcutaneous thickness ratio. Weight reduction was from 101 +/- 17 to 95 +/- 16 kg (P less than 0.001). W/H dropped from 0.83 +/- 0.06 to 0.82 +/- 0.07 (n.s.). VAT dropped from 158 +/- 72 to 134 +/- 61 cm2 (P less than 0.005), SAT from 572 +/- 151 to 566 +/- 164 cm2 (n.s.) and V/S from 0.29 +/- 0.15 to 0.25 +/- 0.11 (P less than 0.01). Abdominal subcutaneous fat thickness decreased from 36 +/- 8 to 35 +/- 10 mm (n.s.), intra-abdominal thickness from 39 +/- 25 to 20 +/- 20 mm (P less than 0.001) and intra-abdominal/subcutaneous from 1.1 +/- 0.7 to 0.8 +/- 0.6 (P less than 0.005). VAT measurement accurately identified small intra-abdominal fat variations. W/H could not evaluate visceral fat loss, because of simultaneous decreases in waist and hip circumferences. Ultrasound was able to measure small reductions in intra-abdominal fat.     

Traumatology in hang-gliding accidents. Studies based on 100 cases

The number of paragliding accidents is growing up exponentially. We review in this study 39 paragliding accidents which occurred 1985-1987 in the Val d'Illiez (Switzerland). The REGA (Swiss air ambulance) rescued 1987 61 pilots, which are also included. Most of the accidents were related to a mistake of the pilot. None is due to a failure of the material. The most severe injuries occurred immediately after taking off. The most frequent injuries occurred during landing. There is a correlation between the altitude, the wind velocity and the severity of the injuries. The lower extremities and the backbone are often injured, which is explained through the axial trauma. The pilots need a better training programme, the performance of the material should be built up and the starting places should be equipped.     

The Changing Spirit of Rural Community Nursing: Documentation Burden

Abstract Rural community and public health nursing are characterized by an impressive commitment of nurses to their communities and a connectedness of people to one another. Home care as an integral part of long-term and acute care for the older adult population has emerged as a vital practice area in community health nursing. The purpose of this ethnographic field study was to describe rural home care for frail older adults from the perspective of those providing and receiving care. More than 250 interviews were conducted with home care providers, recipients and their families, and other community members. The setting included eight culturally and geographically diverse counties in rural Colorado. One major theme is presented: the perceived change in the spirit of rural community nursing due to the overwhelming documentation required for home care reimbursement. Oppressive paperwork requirements impeded practice and resulted in fewer home visits per day, low job satisfaction, increased nursing staff turnover, decreased quality of care, and changed the spirit of community nursing from an emphasis on caring and community service to a focus on reimbursement. The study results have timely implications for health policy formulation as the United States undergoes major health care reform.     

Beta-blockade antagonism of tyramine-induced rise in blood pressure

Summary The effect -adrenoceptor blockade on the pressor response to tyramine has been investigated in 6 healthy volunteers, each submitted to an i.v. tyramine pressor test before and after 7 days of propranolol 40 mg b.d. or indenolol 60 mg o.d. Tyramine was given as i.v. boluses of 1–6 mg, alternating with saline, in a randomized, single blind fashion.Prior to treatment tyramine caused a temporary, dose-dependent increase in systolic and diastolic blood pressure, whilst the heart rate remained unaffected. Both propranolol and indenolol reduced the pressor response to tyramine, as shown by a significant increase in ED₁₅, i.e. the dose of tyramine required to increase systolic blood pressure by 15%.
