Background: Neuroinflammatory diseases are progressive leading to loss of function and disability. Although palliative care (PC) utilization has increased globally, it has scarcely increased in neurology. Objectives: To explore PC attitudes and knowledge among patients with neuroinflammatory diseases, such as multiple sclerosis, neuromyelitis optica spectrum disorder, and myelin oligodendrocyte glycoprotein antibody-associated disease. Methods: A cross-sectional 1-year study was conducted using the Palliative Care Knowledge Scale (PaCKS) and the PC Health Information National Trends Survey (HINTS). Murray's transition theory guided this study, which integrates palliative services including decision making, communication, and coordinated care. Results: The majority of study patients were female (69%) (N = 86) and White (79%). Forty-two percent indicated that they had never heard about PC, 46% said that they knew a little bit about PC, and 12% said that they knew a lot about PC. Fifty percent of patients knew the goals of PC and had knowledge about PC services. Forty-four percent to 60% agreed that PC goals include helping friends and family to cope with a patient's illness, offering social and emotional support, and managing pain and other symptoms. Patients who self-reported being familiar with PC performed significantly better on the PaCKS than those unfamiliar with PC (p < 0.001), and those who self-reported moderate or severe memory loss performed significantly worse on the PaCKS than those with mild memory loss (p = 0.027). There was an association between higher education and PC knowledge and between patients' PaCKS scores and their self-reported HINTS PC knowledge. Conclusions: Patients have partial PC knowledge. Patients require education about PC early in their disease along their illness trajectory. [ABSTRACT FROM AUTHOR]

Introduction: Pain in multiple sclerosis (MS) is common, but literature on pain in children with MS remains scarce. Pain has physical, psychological, and social implications in MS, and both comprehensive assessment and interdisciplinary management approaches are needed. We sought to develop an interdisciplinary interim guideline for the assessment and management of pain in children with MS. Methods and materials: We convened a modified Delphi panel composed of 13 experts in pediatric and adult MS neurology, physiotherapy, pain, patient livedexperience, advanced practice nursing, psychology, physiatry, and MS research. A survey was sent to panelists for anonymous completion. The panel discussed survey themes extracted by the panel chair. The process was repeated twice. Results: Thirteen assessment and treatment recommendations were produced regarding pain in children with MS. Discussion: Future studies will assess implementation of these pain assessment and treatment guidelines in the clinical setting. [ABSTRACT FROM AUTHOR]

Selection for indirect genetic effects (IGE), i.e. the genetic effect of an individual on a trait of another individual, is a promising avenue to increase trait values in plant and animal breeding. Studies in livestock suggest that selection for IGE for growth (IGEg) might increase animals’ capacity to tolerate stress. We assessed the effect of a stressful phase (weaning) on the behaviour and performance of pigs (n = 480) divergently selected for high or low IGEg. High IGEg pigs were significantly slower to explore the feed and gained less weight than low IGEg pigs in the days after weaning. In line with previous findings, high IGEg animals may have prioritized the formation of social ranks. [ABSTRACT FROM AUTHOR]

Interest in cognitive research in pigs is increasing, but little is known about the impact of environmental conditions on pigs' cognitive capabilities. The present study investigated the effect of environmental enrichment on cognitive performance of pigs in a holeboard spatial task, in which they had to discriminate four baited buckets out of 16. Pigs ( n = 32) were either housed in stimulus-poor, barren pens, or in larger pens enriched with rooting substrates. Pigs were subjected to 30 holeboard trials. Both working memory (WM), that is, the ratio (baited visits/total number of (re)visits to baited buckets), and reference memory (RM), that is, the ratio ((re)visits to baited buckets/total number of visits to all buckets), improved over trials. WM scores were higher in pigs from enriched pens than in pigs from barren pens. Housing did not affect RM scores. Personality type of the pigs, as assessed early in life using a backtest, did not affect WM or RM. In conclusion, housing conditions of pigs did not affect reference memory, but environmental enrichment improved working memory of pigs in a spatial discrimination task. Based on the findings of this study, we suggest that cognitive functioning of pigs may be impaired under commonly used housing conditions. [ABSTRACT FROM AUTHOR]

Sulfurtransferases/rhodaneses (Str) are enzymes widely distributed in archaea, prokaryota and eukaryota, and catalyze the transfer of sulfur from a donor molecule to a thiophilic acceptor substrate. In this reaction, Str cycles between the sulfur-free and the sulfur-substituted form. Two-domain Str consist of two globular domains of nearly identical size and conformation connected by a short linker sequence, which is elongated in plant two-domain Str proteins compared to Str in other organisms. The two-domain Arabidopsis thaliana Str1 protein (At1g79230) was expressed in Escherichia coli as a mature protein, as a variant without the elongated linker sequence, and as AtStr1C332S and AtStr1C339V. The persulfuration state of the purified recombinant proteins was investigated in the presence and absence of sulfur donors by fluorescence spectroscopy. The secondary structure was analyzed by circular dichroism (CD) in the far-UV range, while overall changes in tertiary structure were determined by CD in the near-UV range. Finally, protein stability was analyzed by tryptic digestion. The elongated linker sequence is essential for correct conformation and stability, and thereby affects the catalytic activity of AtStr1. Replacement of the catalytic cysteine residue C332 leads to higher rigidity of the molecule, whereas replacement of C339 does not lead to any conformational changes, providing evidence of the direct involvement of C339 in catalysis.
