OBJECTIVES: To improve understanding of how families living in adverse conditions perceive their encounters with public services and how past experiences influence current and future attempts to seek help. DESIGN: Qualitative interviews with adult members of households living in poverty in deprived areas, plus observations conducted in the surrounding neighbourhoods and service settings. PARTICIPANTS: Purposive sample of 25 adults living in a deprived area, on welfare benefits. SETTING: Eight sites in disadvantaged areas in Merseyside, North Wales, London and Greater Manchester in 2004/05. RESULTS: Participants generally perceived public services as a source of distrust and a potential risk to well-being. Encounters with a range of services were perceived as risky in terms of losing resources, being misunderstood or harshly judged, and carrying the ultimate threat of losing custody of their children. Participants perceived that they were subjected to increasing levels of surveillance, with fear of "being told on" by neighbours, in addition to service providers, adding to anxiety. Adverse consequences included avoiding child health and social services, anxiety and self-imposed isolation. CONCLUSIONS: Approaching services was perceived as akin to taking a gamble that might or might not result in their needs being met. Faced with this "choice", participants employed strategies to minimise the risks that on the surface may appear risky to health. If public services are to succeed in providing support to disadvantaged families, greater efforts are needed to build trust and demonstrate understanding for the strategies these families use to maintain their well-being against formidable odds. 相似文献

Ovarian adult‐type granulosa cell tumors (AGCTs) require prolonged follow‐up, but evidence regarding the optimal follow‐up marker is lacking. The objective of our study was to validate the clinical usefulness of serum anti‐Müllerian hormone (AMH) and the current marker inhibin B as single and combined markers of AGCTs. We conducted a longitudinal, partially prospective cohort study of 123 premenopausal and postmenopausal AGCT patients with a median follow‐up time of 10.5 years (range 0.3–50.0 years). Serum AMH and inhibin B levels were measured from 560 pretreatment and follow‐up serum samples by using immunoenzymometric assays. We found that serum AMH and inhibin B levels were significantly elevated in patients with primary or recurrent AGCTs. The levels of both markers positively correlated to tumor size (p < 0.05). AMH and inhibin B performed similarly in receiving operator characteristic analyses; area under the curve (AUC) values were 0.92 [95% confidence interval (CI) 0.88–0.95] for AMH, and 0.94 (95% CI 0.90–0.96) for inhibin B. AMH was highly sensitive (92%) and specific (81%) in detecting a macroscopic AGCT. However, in AUC comparison analyses, the combination of the markers was superior to inhibin B alone. In conclusion, serum AMH is a sensitive and specific marker of AGCT, and either AMH or inhibin B can be monitored during follow‐up. However, combining AMH and inhibin B in AGCT patient follow‐up improves the detection of recurrent disease. 相似文献

Objective
Peer review is the gold standard for evaluating scientific quality. Compared with studies on inter-reviewer variability, research on panel evaluation is scarce. To appraise the reliability of panel evaluations in grant review, we compared scores by two expert panels reviewing the same grant proposals. Our main interest was to evaluate whether panel discussion improves reliability.Methods
Thirty reviewers were randomly allocated to one of the two panels. Sixty-five grant proposals in the fields of clinical medicine and epidemiology were reviewed by both panels. All reviewers received 5-12 proposals. Each proposal was evaluated by two reviewers, using a six-point scale. The reliability of reviewer and panel scores was evaluated using Cohen's kappa with linear weighting. In addition, reliability was also evaluated for the panel mean scores (mean of reviewer scores was used as panel score).Results
The proportion of large differences (at least two points) was 40% for reviewers in panel A, 36% for reviewers in panel B, 26% for the panel discussion scores, and 14% when the means of the two reviewer scores were used. The kappa for panel score after discussion was 0.23 (95% confidence interval: 0.08, 0.39). By using the mean of the reviewer scores, the panel coefficient was similarly 0.23 (0.00, 0.46).Conclusion
The reliability between panel scores was higher than between reviewer scores. The similar interpanel reliability, when using the final panel score or the mean value of reviewer scores, indicates that panel discussions per se did not improve the reliability of the evaluation. 相似文献56.

Neurologic manifestations of infective endocarditis: a 17-year experience in a teaching hospital in Finland 总被引:11,自引:0,他引:11

BACKGROUND: Many previous studies have endeavored to find appropriate means to reduce the occurrence of neurologic manifestations in patients with infective endocarditis (IE). We evaluated patients with IE-associated neurologic complications and compared them with patients with IE who did not have neurologic symptoms. Particular attention was focused on assessing the impact of cardiac surgery and the presence of potential risk factors for complications on the outcome of the patients. METHODS: A total of 218 episodes designated as definite or possible IE according to Duke criteria and treated during the years 1980 through 1996 in a Finnish teaching hospital were retrospectively evaluated for neurologic manifestations. RESULTS: Neurologic complications were identified in 55 episodes (25%), with an embolic event as the most frequent manifestation (23/55; 42%). In the majority (76%) of episodes, the neurologic manifestation was evident before antimicrobial treatment was started, being the first sign of IE in 47% of episodes. Only 1 recurrent cerebral embolization was observed. Neurologic complications were significantly associated with Staphylococcus aureus infection (29% vs 10%; P =.001) and with IE affecting both the aortic and the mitral valves (56% vs 23%; P<.01), but not with echocardiographic detection of vegetations or anticoagulant therapy. Death during the acute phase of IE occurred in 13 episodes (24%) with neurologic complications and in 17 episodes (10%) without neurologic complications (P<.03). In episodes with neurologic complications, the IE-associated mortality rate was 25% (10/40) in the medical treatment group and 20% (3/15) in the surgical group. No neurologic deterioration was observed in these surgically treated patients postoperatively. CONCLUSIONS: Our results reinforce the belief that rapid diagnosis and initiation of antimicrobial therapy may still be the most effective means to prevent neurologic complications. These data underscore the importance of diagnostic alertness to the prognosis of patients with IE. 相似文献
