A food frequency of consumption questionnaire was completed by 137 diabetic outpatients attending the University of Wales Hospital in Cardiff, to provide information about the use of special dietary products.
Seventy-four per cent of the diabetics used special dietary products, the most popular of which were artificial sweeteners (45%) and preserves (47%), followed by squash (34%), sweets (31%) and chocolate (31%). Twenty per cent of diabetics consumed biscuits and tinned fruit. Cake and other products (e.g. jelly), were used by less than 10% of the respondents. Over half of all the diabetics consumed one or more products on a daily basis. The use of special products bore no significant relationship to the sex of the respondents, nor to the duration of the diabetes. However, a significantly higher proportion of the Insulin Dependent Diabetics (IDDM) group used dietary products compared with the Non-Insulin Dependent Diabetics (NIDDM) group. This can be explained largely by the differences in age between the diabetics; the under-18-year-old age group (who were all IDDM respondents) were the greatest users of sweets, chocolate and squash.
Forty-three per cent of diabetics who did not use special food products cited at least one reason for non-use. The reasons included dietetic advice (NIDDM respondents only), high cost, poor palatability, lack of availability and unsuitability for other members of the family. 相似文献

A 53-year-old male with hepatitis C cirrhosis, who had been refused liver transplantation because of hypertrophic cardiomyopathy (HC), underwent nonsurgical septal ablation using alcohol with resolution of his ventricular outflow obstruction. This patient was able to subsequently undergo a successful deceased donor liver transplantation. This is the first reported case of alcohol induced septal ablation being performed in a cirrhotic patient with HC. Such nonsurgical procedures may be attractive in cirrhotic patients who are refused access to liver transplantation because of high surgical risk. 相似文献

Many new insights have been gained over the past 5 years into the mechanisms that regulate immune reactivity to cell and organ transplants. This new knowledge is being applied to the development of innovative experimental strategies that may soon be evaluated in the clinic. 相似文献

Nurses in staff development are responsible for assuring nurses' competence in the delivery of care. Older patients are the predominant population in hospitals, yet there are no instruments that specifically assess the competency of nurses to deliver care to older patients. This article reports on the development and testing of an instrument, Geriatric Competencies for RNs in Hospitals, and makes recommendations as to how staff development educators can use the geriatric competency instrument with staff nurses. 相似文献

A randomized controlled trial of electromagnetic therapy in the primary care management of venous leg ulceration 总被引:1,自引:1,他引:0
OBJECTIVE: The aim was to establish the potential efficacy, tolerabilityand side-effect profile of electromagnetic therapy as an adjunctto conventional dressings in the treatment of venous leg ulcers. METHOD: A prospective, randomized, double blind controlled clinicaltrial was carried out in a dedicated leg ulcer clinic basedin one urban general practice. Nineteen patients with leg ulcersof confirmed venous aetiology were assessed. The main outcomemeasures were rate and scale of venous leg ulcer healing, changesin patient-reported pain levels, quality of life, degree ofmobility, side effect profile and acceptability to patientsand staff. RESULTS: Sixty-eight per cent of patients attending this dedicated clinicachieved improvements in the size of their ulcer (4, 21%, healedfully) and in reduced pain levels (P < 0.05) during the trial,despite the chronicity of ulcer histories. Patients treatedwith electromagnetic therapy at 800 Hz were found at day 50to have significantly greater healing (P < 0.05) and paincontrol (P < 0.05) than placebo therapy or treatment with600 Hz. All patients reported improved mobility at the end ofthe study. The electromagnetic therapy was well tolerated bypatients, with no differences between groups in reporting adverseevents, and proved acceptable to staff. CONCLUSION: Despite the small numbers in this pilot study, electromagnetictherapy provided significant gains in the healing of venousleg ulcers and reduction in pain. Keywords.
