Little is known of the impact of pressure ulceration on adult patients' health-related quality of life. The purpose of this study was to determine the impact pressure ulceration has on pressure ulcer patients cared for in the community. A case control study design was used by drawing a random sample from patients receiving community nursing care, stratified by the presence of pressure ulceration. In all, 75 patients with pressure ulcers were compared with 100 controls without ulcers using the four-point ulcer grading scale described by United Kingdom consensus guidelines. Patients were interviewed using the Short Form-36 (SF-36) questionnaire and activities of daily living assessed using the modified Barthel scale. Patients with pressure ulcers had significantly poorer physical function (mean difference (d) = 37.6, 95% CI 28.6-46.6, p < 0.001) and social functioning (d = 33.9, 95 % CI 24.0-43.9, p < 0.001) than published age- and sex-matched normative data from the United Kingdom. The difference between cases and controls was much smaller in these domains, with neither approaching statistical significance. After adjustment for age and gender, scores for bodily pain were poorer in patients with no ulceration (d = -10.5, 95% CI - 20.6 to - 0.4, p = 0.042) indicating greater pain in these patients compared with the cases with ulceration. Activities of daily living determined by the modified Barthel scale showed reduced self-care (d = -7.6, 95% CI -12.5 to - 2.7, p = 0.010) and mobility (d = -9.2, 95% CI -14.6 to - 3.8, p = 0.001) in patients with pressure ulceration. The overall ability to perform these activities was also significantly poorer in this group (d = -16.3, 95% CI -27.3 to -5.3, p = 0.004). While patients with pressure ulceration experience some deficits in their health-related quality of life compared with a normal population, these differences are similar to those experienced by other patients receiving community nursing care. 相似文献

Four experiments on the metacercariae of Fasciola hepatica and Paramphistomum daubneyi were carried out under natural conditions in order to study their vertical location on submerged plants and to determine whether simultaneous cercarial shedding of both digenea causes changes in the distributions of the metacercariae. These experiments were performed in experimental boxes, each containing six tufts of rushes. Most metacercariae (73.0%) of F. hepatica were found along the walls of boxes, while 81.5% of P. daubneyi metacercariae were found on rush stems. In the case of snails infected by either of the two digenea, 80.1% of F. hepatica cercariae encysted on submerged parts of rushes and of the box walls near the water surface (to a depth of 1 cm), whereas 73.0% of P. daubneyi metacercariae were found in the lower sections (from –4 to –7 cm). If snails dually infected with P. daubneyi and F. hepatica were used, the vertical distributions of the metacercariae were significantly different from those found for snails infected by either of the two digenea. If snails having 42-day old infections with F. hepatica and other snails with 70-day old infections with P. daubneyi were simultaneously introduced into the boxes, the frequency of F. hepatica cysts was significantly lower in the section located under the water surface (29% only), while the frequencies of metacercariae in the lower sections (from –1 to –5 cm) were increased. Some significant changes were also observed for the metacercariae of P. daubneyi. The disturbance noted in the vertical distributions of F. hepatica and P. daubneyi metacercariae suggest that the encystment of F. hepatica cercariae can be disturbed by the simultaneous encystment of P. daubneyi cercariae, or conversely. 相似文献

Missense mutations. three of them novel (Am210→Val, Asn248→ Ile, Ah355→Val), were found in the protein c ( PROC ) genes of 7 patients with inherited protein C deficiency associated with venous thrombosis. Comparison with the phenotypic effects of mutations in the analogous residues of factor IX causing hdernophilia B and the use of molecular modelling has provided explanations as to how these lesions might alter either the structure, function or secretion of the protein C molecules encoded. 相似文献

Hemostatic plug (HP) formation was investigated in the ear bleeding time incision in normal and von Willebrand pigs. HP volume was calculated by integrating the areas of serial sections. In normal pigs (n = 11), platelets immediately formed a layer on the surface of the cut channel. Platelet aggregates formed at the ends of transected vessels and gradually enlarged. Finally, all transected vessels were occluded by HP and bleeding stopped. In contrast, large HPs were formed in the incision in von Willebrand's disease (vWD) pigs (n = 4); these HPs did not cover the ends of the transected vessels, which continued to bleed, allowing the formation of large hemostatically ineffective platelet aggregates in the incision. Canals traversed these HPs, and bleeding from the open vessels may have continued through them. After infusion of cryoprecipitate into a vWD pig, the bleeding time shortened, and the morphological findings of the HPs were similar to those of normal pigs. In normal pigs (n = 3) infused with an anti- Willebrand factor monoclonal antibody, which prolonged the bleeding time, a large HP formed in the incision, similar to that observed in the vWD pig. The volume of the normal and vWD HPs increased with time. These in vivo findings suggest that Willebrand factor is involved in the localization of the HP to the damaged vessel and may also play a role in platelet-platelet interaction. A computerized morphometric technique was used for measuring the volume of the hemostatic plugs and the distance of sequential points on the perimeter of the HP from the center of selected bleeding vessels. 相似文献
