Objective
To develop and validate a nomogram for assessing bladder outlet obstruction (BOO) in women derived from concurrent Pdet.Qmax and Qmax based on radiographic evidence of increased urethral resistance.Patients and Methods
Retrospective analysis of prospectively acquired video‐urodynamics and clinical data of 185 women (development cohort) was performed. The Pdet.Qmax were plotted against Qmax and cluster analysis was performed to determine an axis that best divided the definitively obstructed and unobstructed. Using data from a further 350 women (validation cohort), the sensitivity and specificity of the derived criterion was calculated. Finally, the data from both groups was pooled together and using binary logistic regression analysis, a nomogram was produced.Results
Of the 535 patients in the two cohorts, (122 [22.8%]) demonstrated radiographic evidence of BOO. Cluster analysis identified the axis that best separates the radiographically obstructed and unobstructed as Pdet.Qmax = 2*Qmax. Using the data from the validation cohort, the sensitivity and specificity for this was calculated as 0.94 and 0.93, respectively. A nomogram, representing the probability of BOO for concurrent Pdet.Qmax and Qmax measurements was derived by pooling data from both cohorts. Alternatively, a female BOO index (BOOIf) may be calculated mathematically using the formula BOOIf = Pdet.Qmax ? 2.2*Qmax, that is, BOOIf < 0, <10% probability of obstruction, BOOIf > 5 likely obstructed (50%) and If BOOIf > 18, obstruction almost certain (>90%).Conclusion
A female BOO nomogram (the SG nomogram) with high sensitivity and specificity is proposed. The nomogram can be used to stratify the degree of BOO or assess response to treatment. 相似文献Objective
The present health economic analysis investigated the cost-effectiveness-ratios of either (1) rituximab or (2) an alternative TNF-alpha-inhibiting agent as second line biological treatment in patients with active rheumatoid arthritis (RA) and an inadequate response to etanercept therapy. 相似文献Depression is one of mental health consequences that present in women with obstetric fistula. It is estimated that over 264 million people of all ages suffer from depression globally. The objective of this systematic review and meta-analysis was to synthesize the epidemiologic evidence from previous studies on the prevalence of depression among women with obstetric fistula in low-income African countries. We followed the preferred reporting items for systematic review and meta-analysis (PRISMA) guidelines to conduct this meta-analysis. The common databases (PubMed, SCOPUS, EMBASE, Psych INFO, Google Scholar, African Index Medicus, and African Journals Online (AJOL)) were searched for the relevant literature. We used a random-effect meta-analysis model to estimate the overall prevalence of depression and the Q -and I2 -statistics were used to assess the heterogeneity between the studies included in the meta-analysis. Egger’s test and visual inspection of the symmetry in funnel plots were used to check for the presence of publication bias. The pooled estimated prevalence of depression among women with obstetric fistula in low-income African countries was 56.2% (95% CI 43.1–68.4). The prevalence of depression among women with obstetric fistula was 74.4% in Ethiopia, 72.9% in Kenya, 46.0% in Malawi, 41.0% in Sudan, 34.8% in Nigeria, and 27.7% in Tanzania. Furthermore, the prevalence of depression was higher (97.0%) when it was measured by using Beck’s Depression Inventory (BDI) when compared with Patient Health Questionnaire (PHQ9) (62.7%), General Health Questionnaire (GHQ-28) (36.7%), Hamilton Depression Rating Scale (HDRS) (41.0%), and Center for Epidemiologic Studies Depression Scale (CES-D) (27.7%). Moreover, the pooled estimated prevalence of depression among women with obstetric fistula was ranged from 48.1 to 57.7% in a leave-one-out sensitivity analysis. The prevalence of depression among women with obstetric fistula in low-income African countries was high. Screening and appropriate management of depression among women with obstetric fistula are warranted.
