Lamp light on leadership: clinical leadership and Florence Nightingale Aims The purpose of the present study was to use the example of Florence Nightingales’ nursing experience to highlight the differences between nursing leadership and clinical leadership with a focus on Miss Nightingales’ clinical leadership attributes. Background 2010 marks the centenary of the death of Florence Nightingale. As this significant date approaches this paper reflects on her contribution to nursing in relation to more recent insights into clinical leadership. Evaluation Literature has been used to explore issues related to nursing leadership, clinical leadership and the life and characteristics of Florence Nightingale. Key issues There are a few parts of Florence’s character which fit the profile of a clinical leader. However, Miss Nightingale was not a clinical leader she was a powerful and successful role model for the academic, political and managerial domains of nursing. Conclusion There are other ways to lead and other types of leaders and leadership that nursing and the health service needs to foster, discover and recognize. Implications for nursing management Clinical leaders should be celebrated and recognized in their own right. Both clinical leaders and nursing leaders are important and need to work collaboratively to enhance patient care and to positively enhance the profession of nursing. 相似文献

Background
Clustering of autoimmune diseases is common and may be due to genetic background and exposition to environmental triggers. 相似文献994.
Sports-related muscle injuries: evaluation with MR imaging 总被引:7,自引:0,他引:7
Sports-related muscle pain is frequent in both trained and untrained persons; however, its severity and significance may be difficult to assess clinically. The authors used magnetic resonance (MR) imaging to evaluate acute strains and delayed-onset muscle soreness in sedentary subjects and postmarathon myalgia in trained runners. MR imaging documented the distribution of affected muscles and the absence of focal hematoma, fascial herniation, subsequent fibrosis, and fatty infiltration. Pain associated with strain and that occurring several days after exercise were both associated with prolongation of muscle T1 and T2. In a prospective evaluation of delayed-onset muscle soreness, abnormalities depicted at MR imaging persisted longer than symptoms by up to 3 weeks, indicating that MR imaging is sensitive to tissue alteration that is not apparent clinically. Highly trained marathon runners tended to have relatively mild abnormalities involving the myotendinous junctions. 相似文献

Introduction: The recent National Institutes of Health consensus conference on vaginal birth after cesarean (VBAC) recommended a focus on strategies that increase women's opportunities to make informed choices about VBAC. This study aimed to expand knowledge of women's experiences of planned VBAC by focusing on postnatal experiences of women who participated in an Australian birth‐after‐cesarean study. Methods: At 6 to 8 weeks after birth, 165 women who experienced childbirth after a previous cesarean rated satisfaction with their birth experiences using a 10‐point visual analogue scale, reported on postnatal health problems, and indicated whether they would make the same birth choice again. Results: Significant differences were found in satisfaction scores by mode of birth. Mean scores out of a possible score of 10 ranged from 8.86 for spontaneous vaginal birth, 7.86 for elective repeat cesarean delivery, 6.71 for emergency cesarean delivery, to 6.15 for instrumental vaginal birth (F= 5.33; P= .002). Mean satisfaction scores for spontaneous vaginal birth and elective repeat cesarean delivery were statistically higher than for instrumental vaginal birth and emergency cesarean birth. Women who experienced instrumental vaginal birth and emergency cesarean birth also reported a higher number of postnatal health‐related problems and were least likely to agree that they would make the same birth choice again. Discussion: Mode of birth was the most important determinant of postnatal satisfaction, postnatal health, and whether women felt they would make the same birth choice again. Clinicians, researchers, and policymakers should identify effective labor management practices that enhance women's opportunities to achieve spontaneous vaginal birth during planned VBAC. 相似文献

Association of complement factor B allotypes and serum biomarkers in rheumatoid arthritis patients and their relatives 下载免费PDF全文

The aim of the study was to investigate the allotypic variability of complement factor B (BF) in patients and relatives with rheumatoid arthritis (RA) and its association with serological biomarkers and clinical features of the disease. BF allotypes were determined by high‐voltage agarose gel electrophoresis in serum samples of 180 patients with RA, 198 relatives and 98 controls from Southern Brazil. Anticyclic citrullinated peptide (anti‐CCP), antimutated citrullinated vimentin (anti‐MCV) and IgA‐rheumatoid factor (RF) were determined by ELISA and IgM‐RF by latex agglutination in all samples. No significant differences were found in the allotypic variants of BF between patients with RA, relatives and controls, nor associations with gender and age of RA onset. BF*S07 allotype was significantly associated with extra‐articular manifestations (EAMs; Secondary Sjögren Syndrome, pneumonitis, rheumatoid nodules) in patients with RA (P = 0.02; OR = 6.62). Patients with phenotype BF F had lower positivity for anti‐MCV biomarker (P = 0.02; OR = 0.22) and those with allotype BF*S had higher prevalence of this autoantibody (P = 0.02; OR = 3.77). An increased frequency of RF‐IgA was detected in relatives of patients with RA with BF FS07 phenotype (P = 0.02; OR = 7.78). Complement BF variability did not influence the development of RA in the studied patients, but BF variants may act as markers of disease prognosis, such as development of EAMs, corroborating with the role of the alternative pathway in the pathogenesis of RA. 相似文献

Introduction : Our objective was to determine if there is a difference in rates of perineal injury sustained by nulliparous women attended by obstetricians compared with certified nurse‐midwives (CNMs) at a US community hospital. Methods : We analyzed retrospective data for 2819 women who spontaneously gave birth to singleton, vertex, term, live infants between 2000 and 2005. The independent variable was attendant type (obstetrician or CNM). The main outcome variables were intact perineum, episiotomy, and spontaneous perineal lacerations. Multivariate logistic regression was used to adjust for six potential confounders: macrosomia, maternal age, epidural anesthesia, oxytocin administration, medical insurance status, and ethnicity. Results : The odds ratios (ORs) for obstetrician‐attended births versus CNM‐attended births were significant for a spontaneous minor perineal laceration versus intact perineum (OR = 1.82; 95% confidence interval [CI], 1.33–2.48), spontaneous major laceration versus intact perineum (OR = 2.29; 95% CI, 1.13–4.66), and episiotomy use versus no perineal injury, with or without extension (OR = 2.94; 95% CI, 2.01–4.29). Discussion : We found that the prevalence and severity of perineal injury, both spontaneous and from episiotomy use, were significantly lower in CNM‐attended births.
