Evaluation of a novel co‐designed and co‐delivered training package to de‐escalate violence and aggression in UK acute inpatient, PICU and forensic mental health settings

Background Evidence suggests a discrepancy between recommended and routine practice in de-escalation in mental health settings, suggesting a lack of impact of existing training. Aim To investigate the acceptability and perceived impact of a co-designed/delivered training intervention on a trauma-informed approach to de-escalation on mental health wards. Methods Trainees were invited to complete the Training Acceptability Rating Scale (TARS) post-training. Responses to the quantitative items were summarized using descriptive statistics, and open-text responses were coded using content analysis. Results Of 214 trainees, 211 completed the TARS. The trainees rated the training favourably (median overall TARS = 55/63), as acceptable (median 33/36) and impactful (median 23/27). There were five qualitative themes: modules of interest; multiple perspectives; modes of delivery; moulding to context; and modifying other elements. Discussion The EDITION training was found to be acceptable and impactful, with trainees particularly valuing the co-delivery model. Trainees suggested several ways in which the training could be improved, particularly around the need for further moulding of the intervention to the specific ward contexts/teams. Implications for Practice We recommend co-designing and co-delivering staff training to mental health professionals that tackles restrictive practices. Relevance Statement This research is relevant to lived experience practitioners who want to be involved in training mental health professionals around restrictive practices, demonstrating the value and importance of their voice. It is relevant to current providers of de-escalation training, and to staff receiving training, outlining a novel, but acceptable and impactful, form of training on a key area of mental health practice. It is relevant to anyone with an interest in reducing restrictive practice via co-delivered training

Molecular basis of chemosensitivity of platinum pre-treated ovarian cancer to chemotherapy

Ovarian cancer shows considerable heterogeneity in its sensitivity to chemotherapy both clinically and in vitro. This study tested the hypothesis that the molecular basis of this difference lies within the known resistance mechanisms inherent to these patients' tumours

Combination chemotherapy for choroidal melanoma: ex vivo sensitivity to treosulfan with gemcitabine or Cytosine arabinoside

Treatment of choroidal melanoma by chemotherapy is usually unsuccessful, with response rates of less than 1% reported for dacarbazine (DTIC)-containing regimens which show 20% or more response rates in skin melanoma. Recently, we reported the activity of several cytotoxic agents against primary choroidal melanoma in an ATP-based tumour chemosensitivity assay (ATP-TCA). In this study, we have used the same method to examine the sensitivity of choroidal melanoma to combinations suggested by our earlier study. Tumour material from 36 enucleated eyes was tested against a battery of single agents and combinations which showed some activity in the previous study. The combination of treosulfan with gemcitabine or cytosine arabinoside showed consistent activity in 70% and 86% of cases, respectively. Paclitaxel was also active, particularly in combination with treosulfan (47%) or mitoxantrone (33%). Addition of paclitaxel to the combination of treosulfan + cytosine analogue added little increased sensitivity. For treosulfan + cytosine arabinoside, further sequence and timing experiments showed that simultaneous administration gave the greatest suppression, with minor loss of inhibition if the cytosine analogue was given 24 h after the treosulfan. Administration of cytosine analogue 24 h before treosulfan produced considerably less inhibition at any concentration. While we have so far been unable to study metastatic tumour from choroidal melanoma patients, the combination of treosulfan with gemcitabine or cytosine arabinoside shows activity ex vivo against primary tumour tissue.

Deep Neural Networks for Energy and Position Reconstruction in EXO-200

We apply deep neural networks (DNN) to data from the EXO-200 experiment. In the studied cases, the DNN is able to reconstruct the relevant parameters - total energy and position - directly from raw digitized waveforms, with minimal exceptions. For the first time, the developed algorithms are evaluated on real detector calibration data. The accuracy of reconstruction either reaches or exceeds what was achieved by the conventional approaches developed by EXO-200 over the course of the experiment. Most existing DNN approaches to event reconstruction and classification in particle physics are trained on Monte Carlo simulated events. Such algorithms are inherently limited by the accuracy of the simulation. We describe a unique approach that, in an experiment such as EXO-200, allows to successfully perform certain reconstruction and analysis tasks by training the network on waveforms from experimental data, either reducing or eliminating the reliance on the Monte Carlo.Comment: Accepted version. 33 pages, 28 figure

Search for nucleon decays with EXO-200

A search for instability of nucleons bound in $^{136}$Xe nuclei is reported with 223 kg$\cdot$yr exposure of $^{136}$Xe in the EXO-200 experiment. Lifetime limits of 3.3$\times 10^{23}$ and 1.9$\times 10^{23}$ yrs are established for nucleon decay to $^{133}$Sb and $^{133}$Te, respectively. These are the most stringent to date, exceeding the prior decay limits by a factor of 9 and 7, respectively
