Manual restraint is a hands-on type of physical restraint used to prevent harm to service users and staff, and to administer necessary treatments. This article reports on a review and meta-synthesis of the qualitative literature on healthcare staff's experiences of using manual restraint. Three electronic databases (CINAHL Complete, MEDLINE, and PsycINFO) were systematically searched, and 19 studies were included. Thematic synthesis was used to synthesize the findings. The Critical Appraisal Skills Programme (CASP) checklist was used to appraise study quality. The synthesis generated one overarching interpretive theme, “unpleasant but necessary,” and five subthemes: “maintaining safety triumphs all,” “emotional distress,” “significance of coping,” “feeling conflicted,” and “depletion.” Seven studies indicated that, from staff perspectives, manual restraint was not always used as a last resort. Healthcare staff experience manual restraint as a psychologically and physically unpleasant practice, yet paradoxically deem its use to be sometimes necessary to keep themselves and service users safe from harm. The findings indicate a need for healthcare staff support, post-restraint debriefing meetings with service users, and the implementation of manual restraint minimization programs in healthcare settings. 相似文献

Objective
As apoE−/− and LDL-Receptor−/− mice are commonly used in atherosclerosis research; our objective was to point out the differences in HDL metabolism between mice and humans regarding the roles of apoE and LDLR.Methods
We examined HDL particles obtained from wild type (WT), LDLR−/−, and apoE−/− mice, as well as from normal, homozygous familial hypercholesterolemic (FH), and apoE-deficient human subjects by 2-dimensional non-denaturing PAGE followed by immunoblot and image analysis.Results
In WT mice, the majority of apoA-I was in large (9.0–12.0 nm), α-mobility HDL with trace amounts of apoA-I in small, preβ-1 HDL. In LDL−/− mice, both apoA-I- and apoE-containing HDL looked normal. About one-third of apoE was associated with large apoA-I-containing HDL (LpA-I:E) and two-thirds formed large HDL without apoA-I (LpE). In apoE−/− mice, apoA-I was detected in multiple, β-preβ-mobility, tightly-packed bands (7.0–13.0 nm) indicating that apoA-I in these animals was present only in poorly-lipidated, discoidal particles. Neither FH nor apoE-deficient humans showed significant alterations in apoA-I-containing HDL particles as compared to non-carriers.Conclusions
Our data indicate that apoE is necessary for the formation of spherical, lipidated HDL particles in mice, but not in humans, probably because mice lack CETP. Based on our data, we hypothesize that apoE−/− mice have little or no functional HDL, therefore results from apoE−/− mice cannot be extrapolated to humans without taking this significant difference into consideration. 相似文献94.

Hyperlipidaemia of 18 male and 20 female patients following successful renal transplantation was treated with daily 20 mg
fluvastatin (Lescol) for 12 weeks. The patients were several months after transplantation, and their total cholesterol levels
exceeded 6.5 mmol/l following an 8-week diet. The effect of fluvastatin on the levels of total cholesterol, HDL, LDL, triglyceride,
Apo A1 and Apo B, as well as of lipoprotein(a) was examined. Furthermore, changes of the renal function (GFR-urea, creatinine,
uric acid) and hepatic function (bilirubin, GOT, GPT, CPK, ALP) were followed up, together with the body weight and blood
pressure.
The results of the examinations are summarized as follows: Fluvastatin may be administered effectively and without side effects
in a daily dose of 20 mg in appropriately selected renal transplant patients. The average total cholesterol values, which
were 7.91 mmol/l in men and 7.78 mmol/l in women following the diet, were reduced by 22–25% (p<0.001) after 6 and 12 weeks,
respectively, of fluvastatin treatment. The levels of LDL also decreased significantly (p<0.001): in response to a 20 mg evening
dosage, reduction of more than 25% was observed in 78% of men and 65% of women. Reductions of the Apo B levels were more pronounced
in the females (18.3% men vs. 21.2% women).
The ratio C/HDL-C decreased both in men (from 5.49 to 4.19) and in women (from 4.83 to 4.02). The ratio Apo B/Apo A1 also
decreased (men: from 0.86 to 0.73, women: from 0.73 to 0.66). The concentrations of HDL and Apo A1 did not increase significantly,
the reductions in the levels of triglyceride and lipoprotein(a) were not considerable either. An increase in the levels of
hepatic enzymes and CPK was not encountered during the administration of fluvastatin. In two patients the levels of serum
bilirubin increased by 2–4 μmol/l. Three patients complained about temporary myalgias of the sacroiliac or lumbar region which,
however, were not accompanied by elevated CPK levels. The monitored levels of cyclosporine, urea and creatinine did not increase
significantly during the 12 weeks of treatment. Two patients had temporary gastric complaints. 相似文献

The aim of this study was to provide an overview of the organization and financing of home nursing in the 15 member states in the European Union Home nursing was defined as the nursing care provided at the patients' home by professional home nursing organizations Data were gathered by means of three complementary research methods desk research, postal questionnaire among identified experts and face-to-face interviews with experts The results showed that there are large differences between the countries in the way home nursing care is financed There seems to be a relation between the way of funding and the organizational structure In member states where the organizations receive a fixed budget, based on the number of inhabitants or the demography of the catchment area, home nursing is mainly provided by one type of organization and is freely accessible for the patients In this situation there is little competition among the organizations, and the catchment areas of the regional organizations do not tend to overlap On the other hand, in countries where organizations are reimbursed according to a fee-for-service principle and a referral of a doctor is required, home nursing is provided by different types of organizations and also by independent nurses It seems that fee-for-service reimbursement stimulates competition between providers and a market-oriented home care In addition, a fee-for-service method of funding also has the consequence that mainly technical nursing procedures and some basic care are reimbursed, this leaves little room for nurses to perform preventive and psychosocial activities or to provide more integrated care 相似文献

Abstract Washout holes in the impeller of a centrifugal blood pump reduce thrombus formation in areas where blood is apt to stagnate, especially in the back gap of the impeller. In this study, flow through the washout holes is quantified by pressure measurement and flow visualization with a 300% scaled-up model to understand the force driving flow through the washout holes and the flow itself. When external circuit resistance is constant, pressure distribution normalized by the square of the tip speed is constant and independent of the impeller rotational speed. The ratio of the flow rate through the washout holes to the flow rate of the external circuit is also constant. When the external circuit resistance increases, the pressure difference at the washout holes between the front and back gap of the impeller increases and generates a greater flow rate through the washout holes. 相似文献

The influence of sternal marrow aspiration, iliac crest marrow aspiration, and iliac crest bone biopsy on bone scan appearances was examined. Eighteen patients were scanned a mean of 9.9 days after sternal marrow aspiration with a Salah needle (diameter 1.2 mm). Only one patient had an abnormality at the biopsy site. Bone scans obtained in 9 patients a mean of 10 days after iliac crest trephine marrow biopsy with a Jamshidi needle (diameter 3.5 mm) showed no abnormality at the biopsy site. In 18 patients with metabolic bone disease who had undergone iliac crest bone biopsy with an 8-mm needle, a scan abnormality due to the biopsy was usually present when the interval between the biopsy and the scan was 5 days to 2 months. Patients who were scanned within 3 days of iliac crest bone biopsy or more than 2 months after biopsy had normal scan appearance at the biopsy site. 相似文献

OBJECTIVE: Although stomach is the best choice for reconstruction after esophagectomy from the viewpoint of safety and ease, an intrathoracic stomach, nevertheless, is a poor long-term substitute. This anatomical configuration abolishes normal antireflux mechanisms and places the acid-excreting stomach subject to biliary reflux, moreover, in an adjacent position to the esophagus within the negative-pressure environment of the thorax. METHODS: Between 1995 and 2002, 27 patients with high-grade neoplasia-as early Barrett's carcinoma-or non-dilatable peptic stricture underwent limited surgical resection of the distal esophagus and esophagogastric junction. In 11 of these cases, the reconstruction was performed with gastro-jejuno-duodenal interposition. The long-term functional results of this specially adapted form of interposition reconstruction have been evaluated. The postoperative follow-up period ranged between 24 and 95 months (mean 68 months). Nine patients (9/11=81.8%) have agreed to undergo endoscopy, radiographic contrast-swallow examination, and 24-h ambulatory esophageal pH and bilirubin monitoring. RESULTS: Three out of nine patients (3/9=33%) demonstrated abnormal levels of esophageal acid exposure during the 24-h study period, whilst none had any evidence of bilirubin exposure in the esophageal remnant. Endoscopy revealed that three patients had reflux esophagitis in the remnant esophagus: Los Angeles A=2, C=1. No stomal or jejunal ulceration at the gastro-jejunal anastomosis could be observed. Histopathologic assessment of the squamous epithelial biopsies demonstrated microscopic evidence of inflammation: minor in two cases, moderate in one and major in one case; however, none of them had evidence of columnar metaplasia in the esophageal remnant at a median of 68 months after surgery. The majority of the patients have been doing well since the operation: 8/9 (88%)=Visick I-II. CONCLUSIONS: Gastro-jejuno-duodenal interposition represents an adequate 'second-best' method of choice if technical difficulties emerge with jejunal or colon interposition following limited resection of the esophagus performed due to early Barett's carcinoma or non-dilatable peptic stricture. 相似文献
