Before psychometric instruments can be used for populations other than those for whom they were originally developed, validation of cultural appropriateness is essential. This article describes the assessment of the cultural appropriateness of the Finding Meaning Through Caregiving Scale (FMTCS) with Korean female family caregivers. The FMTCS measures finding meaning among caregivers from an existential perspective and has three subscales: Loss/Powerlessness, Provisional Meaning, and Ultimate Meaning. The instrument's cultural appropriateness was examined through semistructured interviews with ten Korean-born female family caregivers, five caregivers living in Korea, and five living in the United States. The interview data are reported according to the three dimensions described by Flaherty and colleagues (1988): content, semantic, and conceptual equivalence. Although the majority of items of the FMTCS appeared applicable to Korean caregivers, items on the Loss/Powerlessness and Provisional Meaning subscales asking caregivers about feelings related to missing their past relationships or communications appeared inappropriate for many Korean daughters-in-law. Of equal importance, a unique source of meaning among Korean caregivers that is not assessed in the FMTCS is an interpersonal context, including the importance caregivers place on teaching children and feeling proud of one's caregiving accomplishments in the eyes of other relatives. The addition of new items that address the interpersonal context is warranted to improve the instrument's cultural appropriateness for Korean caregivers. 相似文献

Life-threatening hypophosphatemia has been reported after major liver resections with a significant impact on postoperative outcome. Regeneration of the liver may play a crucial role, but the underlying mechanism has not yet been elucidated. This study aims at assessing the effect of vascular control and resected volume of the liver on postoperative phosphorus levels. The study included 30 patients that underwent liver resection. Sixteen patients were operated on without any vascular control and 14 with selective vascular exclusion. Correlation between serum kinetics of phosphorus to resected liver volume and warm ischemia was carried out. All patients experienced low postoperative phosphorus levels. The lowest levels were observed on the second postoperative day, when 40% developed life-threatening hypophosphatemia (< or = 1.1 mg/dl). Warm ischemia and major resections aggravated hypophosphatemia compared with patients operated on without vascular occlusion and with those with minor resections. Vascular exclusion and major resections aggravate hypophosphatemia. Patients who developed hypophosphatemia < or = 1.5 mg/dl were more prone to complications and longer hospital stays compared with counterparts who had serum phosphorus levels > or = 1.6 mg/dl. 相似文献

We investigated the effect of pressure application on the acupuncture point "extra 1" and on a control point on the bispectral index (BIS) values and on stress in 25 volunteers. In each volunteer, pressure was applied on the extra 1 point for 10 min and on a control point for 5 min on different days and in a randomized manner. The BIS value was recorded before applying pressure on the extra 1 point, during pressure application every 30 s for 10 min, and after pressure release. Regarding the control point, BIS values were recorded for 5 instead of 10 min during pressure application because acupressure on that point was associated with an unpleasant feeling. Each volunteer was asked to score stress before and after pressure application from 0 to 10. The BIS values were significantly reduced 2.5, 5, 7.5, and 10 min during pressure application on the extra 1 point (P < 0.001 for each comparison, respectively) and returned to the baseline values after pressure release. Pressure application on the control point decreased BIS values (P < 0.01 and P < 0.05 at 2.5 and 5 min, respectively). However, these values were maintained close to 90% and were significantly higher than those obtained during pressure on the extra 1 point (P < 0.001 and P < 0.001 for the 2.5- and 5-min comparisons). The verbal sedation score values obtained after pressure application on the extra 1 point were also lower when compared with the values obtained after pressure application on the control point (P < 0.001). IMPLICATIONS: This crossover study investigated the effect of pressure application on the acupuncture "extra 1" point in healthy volunteers. Acupressure applied for 10 min on the extra 1 point significantly reduced the BIS values and the verbal stress score when compared with acupressure applied on a control point. 相似文献

The distal end of the ulna is an uncommon site for primary bone tumours. We report the case of a 23-year-old male, with a giant-cell tumour of the distal end of the ulna treated with en-bloc resection and stabilisation of the ulnar stump using one half of the extensor carpi ulnaris tendon. The amount of bone removed from the distal end of the ulna was 9.0 centimeters long. The functional and oncological results were excellent. Stabilisation of the ulnar stump, using one half of the extensor carpi ulnaris tendon, has been described by Goldner and Hayes in 1979, after resection of a relatively small segment of the distal ulna. This is the first report on this technique for stabilisation of the ulnar stump after resection of a large distal ulnar segment. A literature review of reported cases with a resection of the distal ulna for primary bone tumours is presented. The available data are inconclusive as to whether a simple excision is adequate or a reconstruction/stabilisation is required. 相似文献

Primary objective: To investigate the circadian rhythm of serum melatonin in patients with traumatic brain injury (TBI) during Intensive Care Unit (ICU) stay and its relationship with core body temperature fluctuations and measures of severity of their condition.
Methods and procedures: The pilot study was conducted in the ICU of a general hospital in Athens, Greece. Blood melatonin was determined in eight patients consecutively admitted at the ICU following severe head injury, eight times per day during the first and second day following admission. Core body temperature was recorded at hourly intervals. Patients were also assessed with the Glasgow Coma Score (GCS) and the APACHE II score.
Results: Melatonin concentrations were lower than the normally reported values. Mean night-time melatonin levels were higher than mean daytime levels both on the first and second days, although not statistically significant. Diurnal variation of melatonin was associated with the GCS. Thus, patients with low GCS (n = 4) did not exhibit a consistent diurnal variation of melatonin, whereas those with high GCS (n = 4) retained the normally expected fluctuations.
Conclusions: ICU-treated TBI patients exhibit reduced melatonin levels and a circadian secretion profile which is related to the severity of the injury. Patients with more severe head trauma exhibit a clearly disrupted pattern of melatonin secretion, whereas those with less severe trauma preserve a relatively intact diurnal rhythm. Furthermore, the diurnal secretion pattern of melatonin appeared to be dissociated from the circadian rhythm of core body temperature. These preliminary findings may have implications for the management of TBI patients. 相似文献

Diabetes results from an inadequate mass of functional beta-cells. Such inadequacy could result from loss of beta-cells due to an immune assault or the inability to compensate for insulin resistance. Thus, mechanisms that regulate the number of beta-cells will be key to understanding both the pathogenesis of diabetes and for developing therapies. In this study, we show that cell cycle regulator p27 plays a crucial role in establishing the number of beta-cells formed before birth. We show that p27 accumulates in terminally differentiated beta-cells during embryogenesis. Disabling p27 allows newly differentiated beta-cells that are normally quiescent during embryogenesis to reenter the cell cycle and proliferate. As a consequence, excess beta-cells are generated in the p27(-/-) mice, doubling their beta-cell mass at birth. The early postnatal expansion of beta-cell mass was unaffected in p27(-/-) mice, indicating that the main function of p27 is to maintain the quiescent state of newly differentiated beta-cells generated during embryogenesis. The expanded beta-cell mass was accompanied by increased insulin secretion; however, the p27(-/-) mice were glucose intolerant, as these mice were insulin insensitive. To assess the role of p27 to affect regeneration of beta-cells in models of diabetes, p27(-/-) mice were injected with streptozotocin (STZ). In contrast to control mice that displayed elevated blood glucose levels, p27(-/-) mice showed decreased susceptibility to develop STZ-induced diabetes. Furthermore, beta-cells retained the ability to reenter the cell cycle at a far greater frequency in p27(-/-) mice after developing STZ-induced diabetes compared with wild-type littermates. These data indicate that p27 is a key regulator in establishing beta-cell mass and an important target for facilitating beta-cell regeneration in therapies for diabetes. 相似文献

Meta-analysis to investigate the joint effect of multiple factors in the aetiology of a disease is of increasing importance in epidemiology. This task is often challenging in practice, because studies typically concentrate on studying the effect of only one exposure, sometimes may report the interaction between two exposures, but rarely address more complex interactions that involve more than two exposures. In this paper, we develop a meta-analysis framework that combines estimates from studies of multiple exposures. A key development is an approach to combining results from studies that report information on any subset or combination of the full set of exposures. The model requires assumptions to be made about the prevalence of the specific exposures. We discuss several possible model specifications and prior distributions, including information internal and external to the meta-analysis data set, and using fixed-effect and random-effects meta-analysis assumptions. The methodology is implemented in an original meta-analysis of studies relating the risk of bladder cancer to two N-acetyltransferase genes, NAT1 and NAT2, and smoking status. 相似文献

Parenting is a transactional process, influenced by the child’s behavior and the environmental context. The present study
explores the beliefs and practices of parents of aggressive and oppositional adolescents to understand better the relation
among parenting practices, context, and youth violence. Parents of juvenile offenders (N=203) completed assessments of youths’ violent and oppositional behaviors, community violence exposure, and their own beliefs
and parenting behaviors and perceptions of the juvenile justice system. Parents of youth with the highest levels of violent
and oppositional behavior problems reported elevated feelings of hopelessness regarding the child’s future, inadequacy as
a parent, fear of physical harm by the child, anger toward the child, as well as difficulty monitoring the child. All parents
reported relatively high levels of perceived support by the justice system. Parental stress was also examined as a possible
influence on the parents’ beliefs and behaviors regarding the child. Results suggest that parents’ emotional and behavioral
responses should be addressed when intervening with juvenile offenders.
Editors’ Strategic Implications: The authors present evidence to suggest that parents’ perceptions of hopelessness/inadequacy and their fear for their child’s
safety are both by-products of life with an aggressive child as well as contributing factors to that aggressive behavior.
Thus, successful interventions must both target the parents as change agents in the youth’s life but also include a strong
parental support component, so that parents will have an opportunity to orchestrate positive impacts in high-risk environments. 相似文献
