The facilitators and barriers to implementing Emotion Coaching following whole-school training in mainstream primary schools
Initial research into the use of Emotion Coaching (EC) in educational settings has suggested that it can support social and emotional development, and promote positive relationships and behaviour. This research used a sequential mixed-methods design to examine the factors which impact on the implementation of EC. The views of 40 staff across six mainstream primary schools in the UK who had undertaken whole-school training in EC were examined via an online questionnaire. Follow-up semi-structured interviews with 13 staff from two of those schools were analysed using thematic analysis. Key facilitators to implementation included quality training, a school ethos where wellbeing was central, and an actively engaged senior leadership team. Key barriers to implementation were the pressure faced by school staff due to time constraints and curriculum demands. Implications for senior leaders in schools, educational psychologists (EPs), and policymakers are discussed

Controlling a spillover pathway with the molecular cork effect
Spillover of reactants from one active site to another is important in heterogeneous catalysis and has recently been shown to enhance hydrogen storage in a variety of materials. The spillover of hydrogen is notoriously hard to detect or control. We report herein that the hydrogen spillover pathway on a Pd/Cu alloy can be controlled by reversible adsorption of a spectator molecule. Pd atoms in the Cu surface serve as hydrogen dissociation sites from which H atoms can spillover onto surrounding Cu regions. Selective adsorption of CO at these atomic Pd sites is shown to either prevent the uptake of hydrogen on, or inhibit its desorption from, the surface. In this way, the hydrogen coverage on the whole surface can be controlled by molecular adsorption at a minority site, which we term a ‘molecular cork’ effect. We show that the molecular cork effect is present during a surface catalysed hydrogenation reaction and illustrate how it can be used as a method for controlling uptake and release of hydrogen in a model storage syste

Short-term impact of aged garlic extract on endothelial function in diabetes: A randomized, double-blind, placebo-controlled trial.
Impaired endothelial function portends an increased risk of cardiovascular disease. Vascular oxidative stress and systemic inflammation play a critical role in the pathogenesis and progression of vascular disease. Aged garlic extract (AGE) may improve impaired vascular endothelial function, while decreasing the progression of atherosclerotic plaque. We hypothesized that AGE may improve endothelial function, and in this study, we examined this hypothesis to determine whether this can be achieved over a period of 3 months, measured by the cardio-ankle vascular index (CAVI), by reducing intracellular oxidant stress and stimulating nitric oxide generation in endothelial cells. We conducted a double-blinded placebo controlled, randomized clinical trial to investigate the effects of AGE on CAVI in subjects with type 2 diabetes mellitus. A total of 65 individuals (38 men and 27 women) with a mean age of 58.8±11.1 years were enrolled and randomized to the AGE or placebo group in a double-blind placebo controlled trial. An ANOVA model with treatment as the main effect was used to compare changes in CAVI from baseline to follow-up between groups. The primary objective of this study was reduction in CAVI over a 3-month period. In the AGE group, CAVI was reduced on average by 0.71±1.27 vs. a mean reduction of 0.13±0.94 in the placebo group (P=0.04). On the whole, this study demonstrates that AGE has a positive impact on endothelial function in patients with T2DM and may play a role in the primary prevention of cardiovascular disease
IL-1 Generated Subsequent to Radiation-induced Tissue Injury Contributes to the Pathogenesis of Radiodermatitis
Radiation injury in the skin causes radiodermatitis, a condition in which the skin becomes inflamed and the epidermis can break down. This condition causes significant morbidity and if severe it can be an independent factor that contributes to radiation mortality. Radiodermatitis is seen in some settings of radiotherapy for cancer and is also of concern as a complication post-radiation exposure from accidents or weapons, such as a ‘‘dirty bomb’’. The pathogenesis of this condition is incompletely understood. Here we have developed a murine model of radiodermatitis wherein the skin is selectively injured by irradiation with high-energy electrons. Using this model we showed that the interleukin-1 (IL-1) pathway plays a significant role in the development of radiodermatitis. Mice that lack either IL-1 or the IL-1 receptor developed less inflammation and less severe pathological changes in their skin, especially at later time- points. These findings suggest that IL-1 pathway may be a potential therapeutic target for reducing the severity of radiodermatitis

Aged garlic extract reduces low attenuation plaque in coronary arteries of patients with diabetes: A randomized, double-blind, placebo-controlled study.
Several previous studies have demonstrated that aged garlic extract (AGE) inhibits the progression of coronary artery calcification and non-calcified plaque (NCP) in the general population. However, its effects on plaque progression in patients with diabetes have not yet been investigated, at least to the best of our knowledge. This study investigated whether AGE reduces the coronary plaque volume measured by cardiac computed tomography angiography (CCTA) in patients with diabetes mellitus (DM). A total of 80 participants with DM with a median age of 57 years were prospectively assigned to consume 2,400 mg AGE/day (after completion, 37 participants) or placebo (after completion, 29 participants) orally. Both groups underwent CCTA at baseline and follow-up 365 days apart. In total, 66 participants completed the study. Coronary plaque volume, including total plaque (TP), dense calcium (DC), fibrous, fibro-fatty and low-attenuation plaque (LAP) volumes were measured based upon pre-defined intensity cut-off values using semi-automated software (QAngio CT). Changes in various plaque types were normalized to the total coronary artery length. The non-parametric Wilcoxon rank-sum test was performed to examine the differences in plaque formation between the 2 groups. No significant differences were found in the baseline characteristics between the AGE and placebo groups. Compared with the placebo group, the AGE group exhibited a statistically significant regression in normalized LAP [median and standard deviation (SD) -0.2 (18.8) vs. 2.5 (69.3), P=0.0415]. No differences were observed in TP, fibrous, or fibrofatty plaque volumes between the AGE and placebo group. On the whole, this study indicated that the %LAP change in the AGE group was significantly greater than that in the placebo group in patients with diabetes. However, further studies are warranted to evaluate whether AGE has the ability to stabilize vulnerable plaque and decrease adverse cardiovascular events
MDACE: MIMIC Documents Annotated with Code Evidence
We introduce a dataset for evidence/rationale extraction on an extreme
multi-label classification task over long medical documents. One such task is
Computer-Assisted Coding (CAC) which has improved significantly in recent
years, thanks to advances in machine learning technologies. Yet simply
predicting a set of final codes for a patient encounter is insufficient as CAC
systems are required to provide supporting textual evidence to justify the
billing codes. A model able to produce accurate and reliable supporting
evidence for each code would be a tremendous benefit. However, a human
annotated code evidence corpus is extremely difficult to create because it
requires specialized knowledge. In this paper, we introduce MDACE, the first
publicly available code evidence dataset, which is built on a subset of the
MIMIC-III clinical records. The dataset -- annotated by professional medical
coders -- consists of 302 Inpatient charts with 3,934 evidence spans and 52
Profee charts with 5,563 evidence spans. We implemented several evidence
extraction methods based on the EffectiveCAN model (Liu et al., 2021) to
establish baseline performance on this dataset. MDACE can be used to evaluate
code evidence extraction methods for CAC systems, as well as the accuracy and
interpretability of deep learning models for multi-label classification. We
believe that the release of MDACE will greatly improve the understanding and
application of deep learning technologies for medical coding and document
classification
