Cardiovascular disease (CVD) is a complex disease with multifactorial etiology. The presence of endothelial dysfunction constitutes an early risk factor for CVD in children. Circulating microRNAs (miRNAs) are small noncoding RNAs that regulate gene expression and represent a novel class of biomarkers and therapeutic targets; therefore, we examined whether the presence of endothelial dysfunction is associated with differential expression of plasma miRNAs in otherwise healthy children. ⋯ Plasma miRNAs may be useful as potential screening tools for the presence of endothelial dysfunction in children and may reveal endothelial dysfunction-relevant target genes.

Comparative Study
Test-retest reliability of pain-related functional brain connectivity compared to pain self-report.
Test-retest reliability, or reproducibility of results over time, is poorly established for functional brain connectivity (fcMRI) during painful stimulation. As reliability informs the validity of research findings, it is imperative to examine, especially given recent emphasis on using functional neuroimaging as a tool for biomarker development. Although proposed pain neural signatures have been derived using complex, multivariate algorithms, even the reliability of less complex fcMRI findings has yet to be reported. ⋯ Intraclass correlations coefficients for VAS scores ranged from .906 to .947. Overall, self-reported pain was more reliable than fcMRI data. These results highlight that fMRI findings might be less reliable than inherently assumed and have implications for future studies proposing pain markers.

Review'Why can't I give you my organs after my heart has stopped beating?' An overview of the main clinical, organisational, ethical and legal issues concerning organ donation after circulatory death (DCD) in Italy.
Donation after circulatory death (DCD) is a valuable option for the procurement of functioning organs for transplantation. Clinical results are promising and public acceptance is quite good in most western countries. Yet, although DCD is widespread in Europe, several problems still persist in Italy as well as in some other countries. ⋯ Currently, as regards DCD, Italy is somewhat different from other countries. Therefore, every effort should be made for the safe and effective implementation of DCD programs: uncontrolled DCD programs should be promoted and encouraged, within the framework of shared and authoritative rules. At the same time, we need to tackle the question of controlled DCD, promoting debate among all involved subjects regarding the fundamental issues of end-of-life care within protocols that best integrate the highest standard of care for the dying and the legitimate interests of those awaiting a life-saving organ.

Observational Study
Acute exacerbations of chronic obstructive pulmonary disease are associated with increased expression of heparan sulfate and chondroitin sulfate in BAL.
Acute exacerbations of COPD (AECOPDs) are associated with accelerated aggravation of clinical symptoms and deterioration of pulmonary function. The mechanisms by which exacerbations may contribute to airway remodeling and declined lung function are poorly understood. We investigated whether AECOPDs are associated with differential expression of glycosaminoglycans in BAL in a cohort of 97 patients with COPD. ⋯ During AECOPD, there is increased expression of heparan sulfate and chondroitin sulfate in BAL. These molecules are significantly correlated with MMPs in BAL, indicating that they may be associated with airway remodeling and may lead to lung function decline during exacerbations of COPD.

Intrathecal (IT) drug delivery systems (IDDSs) have been valuable in managing refractory chronic cancer and noncancer pain for more than 3 decades. These devices, time tested and overall reliable, have lately been noted at this institution to cease infusing unexpectedly. If not immediately recognized and rectified, this abrupt malfunction may lead to significant patient harm. ⋯ Higher rates of device failure are associated with the use of off-label IT drugs. However, device failure may still occur while infusing only approved medications. Implanted patients should be properly informed and educated to differentiate and recognize the critical error alarm of their device as well as the signs and symptoms of IT medication overdose and withdrawal.
