Myotonic dystrophy type 1 (DM1) lacks non-invasive and easy to measure biomarkers, still largely relying on semi-quantitative tests for diagnostic and prognostic purposes. Muscle biopsies provide valuable data, but their use is limited by their invasiveness. microRNA (miRNAs) are small non-coding RNAs regulating gene expression that are also present in biological fluids and may serve as diseases biomarkers. Thus, we tested plasma miRNAs in the blood of 36 DM1 patients and 36 controls. First, a wide miRNA panel was profiled in a patient subset, followed by validation using all recruited subjects. We identified a signature of nine deregulated miRNAs in DM1 patients: eight miRNAs were increased (miR-133a, miR-193b, miR-191, miR-140-3p, miR-454, miR-574, miR-885-5p, miR-886-3p) and one (miR-27b) was decreased. Next, the levels of these miRNAs were used to calculate a “DM1-miRNAs score”. We found that both miR-133a levels and DM1-miRNAs score discriminated DM1 from controls significantly and Receiver–Operator Characteristic curves displayed an area under the curve of 0.94 and 0.97, respectively. Interestingly, both miR-133a levels and DM1-miRNAs score displayed an inverse correlation with skeletal muscle strength and displayed higher values in more compromised patients.In conclusion, we identified a characteristic plasma miRNA signature of DM1. Although preliminary, this study indicates miRNAs as potential DM1 humoral biomarkers. 相似文献

目的探讨早期活动对ICU机械通气患者谵妄发生的影响。方法将我院2016年10月-2017年4月ICU收治的137例机械通气患者随机分组并进行常规护理干预和早期活动干预,分别在入住ICU后第1天、第2天、第3天及停机械通气时对患者进行谵妄(CAM-ICU)评估、APACHEII评分,并记录患者ICU停留时间,分析早期活动对谵妄发生,病情改善及ICU停留时间的影响。结果与对照组相比,早期活动组在入院第3天后可以显著降低患者的ICU谵妄发生率、APACHEII评分,缩短患者ICU停留时间,差异有统计学意义(P0.05)。结论专业的早期活动可以降低ICU机械通气患者谵妄的发生率,改善患者病情。 相似文献

AimThe aim of this study was to analyse the patients’ role in clinical education in terms of facilitative student-patient relationship in Finland, Germany, Iceland, Ireland, Lithuania and Spain and factors promoting a more facilitative relationship in clinical education.BackgroundNursing students’ bedside learning is reliant on patients and the establishment of a person-centred approach develops from the relationships with patients.DesignA multi-country, cross-sectional design was implemented.MethodsSurvey data were collected from graduating nursing students and patients between May 2018 and March 2019. The survey consisted of a 13-item facilitative sub-scale of the Student-Patient Relationship Scale as the main outcome measure, which was identical for both populations. In addition, background factors were surveyed with single questions and other scales. Associations between facilitative relationship and background factors were studied with linear models.ResultsAltogether, 1796 students and 1327 patients answered the survey. Overall, both students and patients regarded their relationship as facilitative, but students’ (median 4.23, 95% confidence interval 4.15–4.23) evaluations were higher than patients’ (median 3.75, 95% confidence interval 3.69–3.77). The students’ and patients’ evaluations differed from each other significantly in all other countries except in Ireland and Lithuania. Corresponding associations for both populations were found in terms of the country and students’ cultural confidence.ConclusionsResults signal favourable grounds for students’ bedside learning and patient participation in clinical education with the potential to foster a person-centred approach. 相似文献

This article is the first in a series of three, dedicated to the history and functions of what is known as a UMD in France: Unités pour Malades Difficiles, or “Units for Difficult Patients”. This particular article focuses on the oldest such secure structure, UMD Henri Colin, created in 1910 in Villejuif as a quartier de sûreté, or a “secure ward”. The article aims to detail evolutions in treatment and the types of patient treated over more than one hundred years, parallel to social change. Four distinct chronological periods are examined, for their perspective on professional practice as much as for the reasons given for patients’ admission and the psychopathological profiles of “dangerous” patients. Clinical vignettes are used to illustrate this historical evolution. 相似文献
