基于正交试验的肾造瘘管固定方案研究

目的 探讨基于正交试验的肾造瘘管不同固定方案的比较效果。方法 将14Fr硅胶肾造瘘管固定在聚乙烯展板和拉力显示器上，以固定材料、固定方法、面积为3个影响因素，每个因素3个水平，每组进行3次试验再求平均值作为最后拉力值F，共进行9个固定方案共27次试验。利用L9（33）正交试验矩阵研究不同材料（医用橡皮膏、医用透气胶带、医用无纺布胶带）、固定方法（交叉固定法、“工”字固定法和改良“工”字固定法）及面积(16 cm2、24 cm2、32 cm2）对肾造瘘管固定强度的影响。结果 正交试验所选的3种影响因素中，对拉力值影响显著性排序为：材料＞方法＞面积；3种固定材料中，医用橡皮膏固定强度最大。结论 肾造瘘管固定方案中，最佳固定组合为以医用橡皮膏结合改良“工”字法固定，可为临床管道固定方案的选择提供参考。     

CD19 + CD21lo/neg cells are increased in systemic sclerosis-associated interstitial lung disease

Interstitial lung disease (ILD) represents a significant cause of morbidity and mortality in systemic sclerosis (SSc). The purpose of this study was to examine recirculating lymphocytes from SSc patients for potential biomarkers of interstitial lung disease (ILD). Peripheral blood mononuclear cells (PBMCs) were isolated from patients with SSc and healthy controls enrolled in the Vanderbilt University Myositis and Scleroderma Treatment Initiative Center cohort between 9/2017–6/2019. Clinical phenotyping was performed by chart abstraction. Immunophenotyping was performed using both mass cytometry and fluorescence cytometry combined with t-distributed stochastic neighbor embedding analysis and traditional biaxial gating. This study included 34 patients with SSc-ILD, 14 patients without SSc-ILD, and 25 healthy controls. CD21^lo/neg cells are significantly increased in SSc-ILD but not in SSc without ILD (15.4 ± 13.3% vs. 5.8 ± 0.9%, p = 0.002) or healthy controls (5.0 ± 0.5%, p < 0.0001). While CD21^lo/neg B cells can be identified from a single biaxial gate, tSNE analysis reveals that the biaxial gate is comprised of multiple distinct subsets, all of which are increased in SSc-ILD. CD21^lo/neg cells in both healthy controls and SSc-ILD are predominantly tBET positive and do not have intracellular CD21. Immunohistochemistry staining demonstrated that CD21^lo/neg B cells diffusely infiltrate the lung parenchyma of an SSc-ILD patient. Additional work is needed to validate this biomarker in larger cohorts and longitudinal studies and to understand the role of these cells in SSc-ILD.

     

Desarrollo y validación de la versión abreviada del Transsexual Voice Questionnaire for Male-to-Female Transsexuals en español

ObjectiveThe aim of this study was to create and validate an abbreviated version of the Spanish Transsexual Voice Questionnaire for Male-to-Female Transsexuals (SvTVQ^MtF).SettingThe study was conducted by two referral hospitals for voice feminization surgery and by a university department of psychology and speech therapy, all in Spain.Subjects and methodsWe prospectively studied 51 male-to-female transsexuals who underwent voice feminization surgery between January 2017 and December 2018. The SvTVQ^MtF was completed before and after surgery, and the 10 items with the greatest variation were selected by clinical consensus of an expert panel to develop the short version of the SvTVQ^MtF (SvTVQ^MtF-10). The correlation between the total score and the score for each item on the SvTVQ^MtF and the SvTVQMtF-10 was studied. The internal consistency of the SvTVQ^MtF-10 was analysed.ResultsGood correlation (Pearson coefficient above .90) was found between the two questionnaires. A significant correlation was found between the total SvTVQ^MtF-10 score and the score for each item. A significant negative correlation was found between the SvTVQ^MtF and fundamental frequency after voice feminization surgery. Cronbach's α was .79.ConclusionThe SvTVQ^MtF-10 is a valid short version of the SvTVQ^MtF and can be used to quantify voice-related quality of life in MtF transsexuals.
