Determining the minimally clinically important difference for the pediatric liver transplant quality of life questionnaire.

Purpose: The Pediatric Liver Transplant Quality of Life (PeLTQL) questionnaire is a disease-specific patient reported outcome measure for pediatric liver transplant (LT) recipients. To-date, threshold values above which a change in PeLTQL score is considered meaningful to patients are unavailable. This study proposes the first values for the minimally clinically important difference (MCID) for the PeLTQL.

Is the process of withdrawal of life-sustaining measures in the intensive care unit different for deceased organ donors compared with other dying patients? A secondary analysis of prospectively collected data.

Objective: To investigate whether observable differences exist between patterns of withdrawal of life-sustaining measures (WLSM) for patients eligible for donation after circulatory death (DCD) in whom donation was attempted compared with those patients in whom no donation attempts were made.

Setting: Adult intensive care units from 20 centres in Canada, the Czech Republic and the Netherlands.

Design: Secondary analysis of quantitative data collected as part of a large, prospective, cohort study (the Death Prediction and Physiology after Removal of Therapy study).

Evaluating the performance of propensity score matching based approaches in individual patient data meta-analysis.

Background: Individual-patient data meta-analysis (IPD-MA) is an increasingly popular approach because of its analytical benefits. IPD-MA of observational studies must overcome the problem of confounding, otherwise biased estimates of treatment effect may be obtained. One approach to reducing confounding bias could be the use of propensity score matching (PSM).

Effect of continuous positive airway pressure treatment of obstructive sleep apnea-hypopnea in multiple sclerosis: A randomized, double-blind, placebo-controlled trial (SAMS-PAP study).

Objective: The aim of this study was to evaluate the effect of continuous positive airway pressure (CPAP) treatment on the Fatigue Severity Scale (FSS, preplanned primary outcome), another fatigue measure, sleep quality, somnolence, pain, disability, and quality of life in multiple sclerosis (MS) patients with obstructive sleep apnea-hypopnea (OSAH).

Methods: In a randomized, double-blind trial (NCT01746342), MS patients with fatigue, poor subjective sleep quality, and OSAH (apnea-hypopnea index of ⩾ 15 events per hour/sleep), but without severe OSAH (apnea-hypopnea index > 30, and 4% oxygen desaturation index > 15 events/hour or severe somnolence), were randomized to fixed CPAP or sham CPAP for 6 months. Outcome assessments were performed at 3 and 6 months.

Sarcopenia in Children With End-Stage Liver Disease on the Transplant Waiting List.

Sarcopenia predicts morbidity and mortality in adults with end-stage liver disease (ESLD) and is determined by total psoas muscle area (tPMA) measurement from computed tomography (CT) imaging. Recently developed pediatric age- and sex-specific tPMA growth curves provide the opportunity to ascertain prevalence and impact of sarcopenia in children awaiting liver transplantation (LT). This retrospective single-center study evaluated sarcopenia in children between 1 and 16 years with ESLD and a clinically indicated abdominal CT less than 3 months before first isolated LT.
