- In this large multiple system atrophy cohort, Chelban et al. show that plasma NfL correlates with clinical disease severity, progression and prognosis, and could help inform patient stratification and monitor treatment responses in future trials of putative disease-modifying agents. Disease-modifying treatments are currently being trialled in multiple system atrophy. Approaches based solely on clinical measures are challenged by heterogeneity of phenotype and pathogenic complexity. Neurofilament light chain protein has been explored as a reliable biomarker in several neurodegenerative disorders but data on multiple system atrophy have been limited. Therefore, neurofilament light chain is not yet routinely used as an outcome measure in multiple system atrophy. We aimed to comprehensively investigate the role and dynamics of neurofilament light chain in multiple system atrophy combined with cross-sectional and longitudinal clinical and imaging scales and for subject trial selection. In this cohort study, we recruited cross-sectional and longitudinal cases in a multicentre European set-up. Plasma and CSF neurofilament light chain concentrations were measured at baseline from 212 multiple system atrophy cases, annually for a mean period of 2 years in 44 multiple system atrophy patients in conjunction with clinical, neuropsychological and MRI brain assessments. Baseline neurofilament light chain characteristics were compared between groups. Cox regression was used to assess survival; receiver operating characteristic analysis to assess the ability of neurofilament light chain to distinguish between multiple system atrophy patients and healthy controls. Multivariate linear mixed-effects models were used to analyse longitudinal neurofilament light chain changes and correlated with clinical and imaging parameters. Polynomial models were used to determine the differential trajectories of neurofilament light chain in multiple system atrophy. We estimated sample sizes for trials aiming to decrease neurofilament light chain levels. We show that in multiple system atrophy, baseline plasma neurofilament light chain levels were better predictors of clinical progression, survival and degree of brain atrophy than the neurofilament light chain rate of change. Comparative analysis of multiple system atrophy progression over the course of disease, using plasma neurofilament light chain and clinical rating scales, indicated that neurofilament light chain levels rise as the motor symptoms progress, followed by deceleration in advanced stages. Sample size prediction suggested that significantly lower trial participant numbers would be needed to demonstrate treatment effects when incorporating plasma neurofilament light chain values into multiple system atrophy clinical trials in comparison to clinical measures alone. In conclusion, neurofilament light chain correlates with clinical disease severity, progression and prognosis in multiple system atrophy. Combined with clinical and imaging analysis, neurofilament light chain can inform patient stratification and serve as a reliable biomarker of treatment response in future multiple system atrophy trials of putative disease-modifying agents.

- Background: Hypermetabolism and muscle wasting frequently occur in patients with severe emphysema. Improving respiratory mechanics by bronchoscopic lung volume reduction (BLVR) might contribute to muscle maintenance by decreasing energy requirements and alleviating eating-related dyspnoea. Objective: The goal was to assess the impact of BLVR on energy balance regulation. Design: Twenty emphysematous subjects participated in a controlled clinical experiment before and 6 months after BLVR. Energy requirements were assessed: basal metabolic rate (BMR) by ventilated hood, total daily energy expenditure (TDEE) by doubly labelled water, whole body fat-free mass (FFM) by deuterium dilution, and physical activity by accelerometry. Oxygen saturation, breathing rate, and heart rate were monitored before, during, and after a standardized meal via pulse oximetry and dyspnoea was rated. Results: Sixteen patients completed follow-up, and among those, 10 patients exceeded the minimal clinically important difference of residual volume (RV) reduction. RV was reduced with median (range) 1,285 mL (-2,430, -540). Before BLVR, 90% of patients was FFM-depleted despite a normal BMI (24.3 +/- 4.3 kg/m(2)). BMR was elevated by 130%. TDEE/BMR was 1.4 +/- 0.2 despite a very low median (range) daily step count of 2,188 (739, 7,110). Following BLVR, the components of energy metabolism did not change significantly after intervention compared to before intervention, but BLVR treatment decreased meal-related dyspnoea (4.1 vs. 1.7, p = 0.019). Conclusions: Impaired respiratory mechanics in hyperinflated emphysematous patients did not explain hypermetabolism.

- BACKGROUND: The prevalence of pressure injuries among community-dwelling older adults in countries worldwide is still a serious problem. In Indonesia, older adults mostly rely on family members for (medical) care. Therefore, involving family members in the prevention and treatment of pressure injuries (PIs) could potentially decrease its prevalence rates. However, family members are usually not trained for such tasks. Hence, it is essential to first get more insight into the current state of affairs on family members' knowledge, attitude and actual practice of preventing PIs. Due to the lack of an existing instrument to measure knowledge, attitude and practice of family caregivers in preventing PIs, this study focuses on the development and evaluation of psychometric properties of such an instrument.METHODS: Three phases of instrument development and evaluation were used, including item generation, instrument construction and psychometric testing of the instrument. A total of 372 family caregivers of community-dwelling older adults who randomly selected participated in this study. Principal factor analysis, confirmatory factor analysis and Cronbach's alpha were performed to evaluate factor structure and internal consistency of the Knowledge, Attitude and Practice of Family Caregivers at Preventing Pressure Injuries (KAP-PI) instrument.RESULTS: The final version of the KAP-PI-instrument consists of a 12-item knowledge domain, a 9-item attitude domain, and a 12-item practice domain with Cronbach's Alpha values of 0.83, 0.93 and 0.89, respectively. The instrument appeared to be both reliable and valid.CONCLUSION: The KAP-PI instrument can be used in family nursing or community nursing practice, education, and research to assess knowledge, attitude and practice of pressure injury prevention of family caregivers.

- Breathlessness is one of the most frequent symptoms in chronic obstructive pulmonary disease (COPD). COPD may result in disability, decreased productivity and increased healthcare costs. The presence of comorbidities increases healthcare utilization. However, the impact of breathlessness burden on healthcare utilization and daily activities is unclear. This study’s goal was to analyze the impact of breathlessness burden on healthcare and societal costs. In this observational single-center study, patients with COPD were followed-up for 24 months after completion of a comprehensive pulmonary rehabilitation program. Every three months participants completed a cost questionnaire, covering healthcare utilization and impact on daily activities. The results were compared between participants with low (modified Medical Research Council (mMRC) grade <2; LBB) and high baseline breathlessness burden (mMRC grade ≥2; HBB). Healthcare costs in year 1 were €7302 (95% confidence interval €6476–€8258) for participants with LBB and €10,738 (€9141–€12,708) for participants with HBB. In year 2, costs were €8830 (€7372-€10,562) and €14,933 (€12,041–€18,520), respectively. Main cost drivers were hospitalizations, contact with other healthcare professionals and rehabilitation. Costs outside the healthcare sector in year 1 were €682 (€520–€900) for participants with LBB and €1520 (€1210–€1947) for participants with HBB. In year 2, costs were €829 (€662–€1046) and €1457 (€1126–€1821) respectively. HBB in patients with COPD is associated with higher healthcare and societal costs, which increases over time. This study highlights the relevance of reducing costs with adequate breathlessness relief. When conventional approaches fail to improve breathlessness, a personalized holistic approach is warranted. © 2021 The Author(s). Published with license by Taylor & Francis Group, LLC.
