Family perspectives on facilitators and barriers to the set up and conduct of virtual visiting in intensive care during the COVID-19 pandemic: a qualitative interview study
Objective: To gain perspectives from family members about barriers and facilitators to virtual visit set up and conduct across intensive care unit settings in the United Kingdom to inform understanding of best practices. Methods: We conducted a qualitative descriptive study recruiting a purposive sample of family members of adult intensive care unit patients experiencing virtual visiting during Jan to May 2021 of the COVID-19 pandemic. We used semi-structured qualitative interviews and a standard Thematic Analysis approach. Results: We recruited 41 family-member participants from 16 hospitals in the United Kingdom. Facilitators to successful virtual visit set-up were preparation of the family, negotiating a preferred time, and easy-to-use technology. Facilitators to successful conduct were intensive care unit team member presence; enabling family involvement in care; inclusivity, accessibility, and flexibility; and having a sense of control. Barriers that created distress or conflict included restrictive virtual visiting practices; raising expectations then failing to meet them; lack of virtual visit pre-planning; and failing to prepare the patient. Barriers to visit conduct were incorrect camera positioning, insufficient technical and staff resources, issues with three-way connectivity, and lack of call closure. Recommendations included emotional self-preparation, increased technology availability, and preparing conversation topics. Conclusion: These data may guide virtual visiting practices during the ongoing pandemic but also to continue virtual visiting outside of pandemic conditions. This will benefit family members suffering from ill health, living at a distance, unable to afford travel, and those with work and care commitments, thereby reducing inequities of access and promoting family-centered care.</p
Family Caregiver Perspectives on Digital Methods to Measure Stress: Qualitative Descriptive Study
Background:Family caregivers provide essential care in the home to millions of individuals around the globe annually. However, family caregiving results in considerable burden, financial hardship, stress, and psychological morbidity. Identifying and managing stress in caregivers is important as they have a dual role in managing their own health as well as that of the person they care for. If stress becomes overwhelming, a caregiver may no longer be able to perform this essential role. Digital methods of stress monitoring may be 1 strategy for identifying effective interventions to relieve caregiver burden and stress.Objective:This study aims to explore the perceived acceptability, challenges, and opportunities of using digital and biosensing technologies to measure caregiver stress.Methods:We conducted a descriptive qualitative study using semistructured interviews with an interview guide structured to obtain qualitative data addressing our study aims. We used reflexive thematic analysis methods. We recruited adult family caregivers (aged 18 years and older) currently or previously caring for an adult in the home with significant health issues. Interview questions focused on stress monitoring more generally and on ecological momentary assessment, remote monitoring technologies such as smartwatches, and fluid biosensors.Results:We recruited 27 family caregivers of whom 19 (70%) were currently in a caregiving role, and the remainder were previously in a caregiving role. We identified 3 themes with 10 subthemes addressing elements of acceptability, challenges, and opportunities of using digital and biosensing technologies to measure caregiver stress The themes comprised “providing meaningful data” with subthemes of “monitoring without action is pointless,” “monitoring that enables self-management,” and “seeing the bigger picture”; “low-burden monitoring” with subthemes of “low effort,” “practical alongside daily routines,” and “retaining control over monitoring”; and “inadvertent harms of stress monitoring” with subthemes of “stigma of stress,” “need for discretion,” “contributing to stress,” and “trust.”Conclusions:In this descriptive qualitative study examining the perspectives of a diverse sample of family caregivers on methods of stress monitoring, we identified 3 themes addressing elements of acceptability, challenges, and opportunities. These provide useful considerations for the use of stress monitoring and implementation of interventions to ameliorate family caregivers’ stress of relevance to social care and community teams, researchers, and policy makers. These include providing meaningful situationally specific data resulting in action, that does not contribute to caregiver burden, or inadvertent harm to either the caregiver or the care recipient
Reconstruction of primary vertices at the ATLAS experiment in Run 1 proton–proton collisions at the LHC
This paper presents the method and performance of primary vertex reconstruction in proton–proton collision data recorded by the ATLAS experiment during Run 1 of the LHC. The studies presented focus on data taken during 2012 at a centre-of-mass energy of √s=8 TeV. The performance has been measured as a function of the number of interactions per bunch crossing over a wide range, from one to seventy. The measurement of the position and size of the luminous region and its use as a constraint to improve the primary vertex resolution are discussed. A longitudinal vertex position resolution of about 30μm is achieved for events with high multiplicity of reconstructed tracks. The transverse position resolution is better than 20μm and is dominated by the precision on the size of the luminous region. An analytical model is proposed to describe the primary vertex reconstruction efficiency as a function of the number of interactions per bunch crossing and of the longitudinal size of the luminous region. Agreement between the data and the predictions of this model is better than 3% up to seventy interactions per bunch crossing
Communication and virtual visiting for families of patients in intensive care during the COVID-19 pandemic:A UK National Survey
© 2021 by the American Thoracic Society. This article is open access and distributed under the terms of the Creative Commons Attribution Non-Commercial No Derivatives License 4.0.https://creativecommons.org/licenses/by-nc-nd/4.0/Rationale: Restriction or prohibition of family visiting intensive care units (ICUs) during the coronavirus disease (COVID-19) pandemic poses substantial barriers to communication and family- and patient-centered care. Objectives: To understand how communication among families, patients, and the ICU team was enabled during the pandemic. The secondary objectives were to understand strategies used to facilitate virtual visiting and associated benefits and barriers. Methods: A multicenter, cross-sectional, and self-administered electronic survey was sent (June 2020) to all 217 UK hospitals with at least one ICU. Results: The survey response rate was 54%; 117 of 217 hospitals (182 ICUs) responded. All hospitals imposed visiting restrictions, with visits not permitted under any circumstance in 16% of hospitals (28 ICUs); 63% (112 ICUs) of hospitals permitted family presence at the end of life. The responsibility for communicating with families shifted with decreased bedside nurse involvement. A dedicated ICU family-liaison team was established in 50% (106 ICUs) of hospitals. All but three hospitals instituted virtual visiting, although there was substantial heterogeneity in the videoconferencing platform used. Unconscious or sedated ICU patients were deemed ineligible for virtual visits in 23% of ICUs. Patients at the end of life were deemed ineligible for virtual visits in 7% of ICUs. Commonly reported benefits of virtual visiting were reducing patient psychological distress (78%), improving staff morale (68%), and reorientation of patients with delirium (47%). Common barriers to virtual visiting were related to insufficient staff time, rapid implementation of videoconferencing technology, and challenges associated with family members’ ability to use videoconferencing technology or access a device. Conclusions: Virtual visiting and dedicated communication teams were common COVID-19 pandemic innovations addressing the restrictions to family ICU visiting, and they resulted in valuable benefits in terms of patient recovery and staff morale. Enhancing access and developing a more consistent approach to family virtual ICU visits could improve the quality of care, both during and outside of pandemic conditions.Peer reviewedFinal Published versio
Digital peer-to-peer support programme for informal caregivers of people living with motor neuron disease:study protocol for a multi-centre parallel group, single-blinded (outcome assessor) randomised controlled superiority trial
Background: Peer support is effective in improving psychological well-being of family caregivers of people with conditions such as dementia, cancer, and brain injury. However, there are limited data on effective psychological interventions for family caregivers of people living with motor neurone disease. Our objective is to evaluate the efficacy of a virtual peer support programme for improving caregiver psychological wellbeing and caregiving related outcomes. Methods: We will conduct a multi-centre parallel group randomised controlled superiority trial. Using a multi-modal recruitment strategy, we will recruit informal caregivers from UK MND clinics, in-patient units, and hospices. We will randomise (1:1, stratified by gender) participants to either a 12-week virtual peer support programme or usual care comprising provision of online information resources publicly available via the MND Association website. Peer support programme elements will be delivered via a secure digital e-platform aTouchAway™ (Aetonix, Canada). Our target sample size is 160 (80 each arm). Our primary outcome is the Hospital Anxiety and Depression Scale (HADS) assessed at 12 weeks (primary endpoint). Secondary outcomes that will also be assessed at 12 weeks include the Zarit Burden Interview, Pearlin Mastery Scale, Personal Gain Scale, Positive Affect Scale, and the Brief COPE. Outcome assessors will be blinded to allocation. Tertiary outcomes include perceived usability (1 item 9-point Likert scale) and acceptability (semi-structured qualitative interviews) of the peer support programme. Intervention fidelity measures will comprise frequency, type (text, audio, video), and duration (audio and video) of peer support contact downloaded from the aTouchAway AWS server. We will use a mixed-effects linear model to test the effect of the intervention on the primary outcome. Secondary outcomes will be analysed using linear regression. We have ethical approval (21/NW/0269) from the North-West Research Ethics Committee, UK. Discussion: This single-blinded randomised controlled trial will determine the effect of a virtual peer support programme on caregiver psychological wellbeing and caregiver burden. This study will examine the impact of a virtual peer support intervention on quality-of-life measures in informal caregivers of individuals with MND living in the community.

ARF6-Dependent Regulation of P2Y Receptor Traffic and Function in Human Platelets
Adenosine diphosphate (ADP) is a critical regulator of platelet activation, mediating its actions through two G protein-coupled receptors, the P2Y1 and P2Y12 purinoceptors. Recently, we demonstrated that P2Y1 and P2Y12 purinoceptor activities are rapidly and reversibly modulated in human platelets, revealing that the underlying mechanism requires receptor internalization and subsequent trafficking as an essential part of this process. In this study we investigated the role of the small GTP-binding protein ADP ribosylation factor 6 (ARF6) in the internalization and function of P2Y1 and P2Y12 purinoceptors in human platelets. ARF6 has been implicated in the internalization of a number of GPCRs, although its precise molecular mechanism in this process remains unclear. In this study we show that activation of either P2Y1 or P2Y12 purinoceptors can stimulate ARF6 activity. Further blockade of ARF6 function either in cell lines or human platelets blocks P2Y purinoceptor internalization. This blockade of receptor internalization attenuates receptor resensitization. Furthermore, we demonstrate that Nm23-H1, a nucleoside diphosphate (NDP) kinase regulated by ARF6 which facilitates dynamin-dependent fission of coated vesicles during endocytosis, is also required for P2Y purinoceptor internalization. These data describe a novel function of ARF6 in the internalization of P2Y purinoceptors and demonstrate the integral importance of this small GTPase upon platelet ADP receptor function
Linkage mapping evidence for a syntenic QTL associated with flowering time in perennial C<sub>4</sub> rhizomatous grasses Miscanthus and switchgrass
Flowering in perennial species is directed via complex signalling pathways that adjust to developmental regulations and environmental cues. Synchronized flowering in certain environments is a prerequisite to commercial seed production, and so the elucidation of the genetic architecture of flowering time in Miscanthus and switchgrass could aid breeding in these underdeveloped species. In this context, we assessed a mapping population in Miscanthus and two ecologically diverse switchgrass mapping populations over 3 years from planting. Multiple flowering time quantitative trait loci (QTL) were identified in both species. Remarkably, the most significant Miscanthus and switchgrass QTL proved to be syntenic, located on linkage groups 4 and 2, with logarithm of odds scores of 17.05 and 21.8 respectively. These QTL regions contained three flowering time transcription factors: Squamosa Promoter-binding protein-Like, MADS-box SEPELLATA2 and gibberellin-responsive bHLH137. The former is emerging as a key component of the age-related flowering time pathway.</p
Title: Family caregiver perspectives on digital methods to measure of stress: a qualitative descriptive study
Background
Family caregivers provide essential care in the home to millions of individuals around the globe annually. However, family caregiving results in considerable burden, financial hardship, stress and psychological morbidity. Identifying and managing stress in caregivers is important as they have a dual role in manging their own health as well as that of the person they care for. If stress becomes overwhelming, a caregiver may no longer be able to perform this essential role. Digital methods of stress monitoring may be one strategy of identifying effective interventions to relieve caregiver burden and stress.
Objective
To explore perceived acceptability, challenges, and opportunities of using digital and biosensing technologies to measure caregiver stress.
Methods
We conducted a descriptive qualitative study using semi-structured interviews and reflexive thematic analysis methods. We recruited adult family caregivers (18 years) currently or previously caring for an adult in the home with significant health issues. Interview questions focused on stress monitoring more generally and on ecological momentary assessment, remote monitoring technologies such as smartwatches, and fluid biosensors.
Results
We recruited 27 family caregivers of whom 70% were currently in a caregiving role, the remainder were previously in a caregiving role. We identified three themes with ten subthemes. Themes comprised ‘Providing meaningful data’ with subthemes of ‘Monitoring without action is pointless’; ‘Monitoring that enables self-management’ and ‘Seeing the bigger picture’; ‘Low burden monitoring’ with subthemes of ‘Low effort’, ‘Practical alongside daily routines’ and ‘Retaining control over monitoring’; and ‘Inadvertent harms of stress monitoring’ with subthemes of ‘Stigma of stress’, ‘Need for discretion’, ‘Contributing to stress’, and ‘Trust’.
Conclusion
In this descriptive qualitative study examining the perspectives of a diverse sample of family caregivers on methods of stress monitoring we identified three themes. These provide useful considerations for use of stress monitoring and implementation of interventions to ameliorate family caregiver stress of relevance to social care and community teams, researchers, and policy makers. These include providing meaningful situationally specific data resulting in action, that does not contribute to caregiver burden, or in inadvertent harm to either the caregiver or the care recipient
Long-term risk prediction after major lower limb amputation: 1-year results of the PERCEIVE study
Background: Decision-making when considering major lower limb amputation is complex and requires individualized outcome estimation. It is unknown how accurate healthcare professionals or relevant outcome prediction tools are at predicting outcomes at 1-year after major lower limb amputation. Methods: An international, multicentre prospective observational study evaluating healthcare professional accuracy in predicting outcomes 1 year after major lower limb amputation and evaluation of relevant outcome prediction tools identified in a systematic search of the literature was undertaken. Observed outcomes at 1 year were compared with: healthcare professionals' preoperative predictions of death (surgeons and anaesthetists), major lower limb amputation revision (surgeons) and ambulation (surgeons, specialist physiotherapists and vascular nurse practitioners); and probabilities calculated from relevant outcome prediction tools. Results: A total of 537 patients and 2244 healthcare professional predictions of outcomes were included. Surgeons and anaesthetists had acceptable discrimination (C-statistic = 0.715), calibration and overall performance (Brier score = 0.200) when predicting 1-year death, but performed worse when predicting major lower limb amputation revision and ambulation (C-statistics = 0.627 and 0.662 respectively). Healthcare professionals overestimated the death and major lower limb amputation revision risks. Consultants outperformed trainees, especially when predicting ambulation. Allied healthcare professionals marginally outperformed surgeons in predicting ambulation. Two outcome prediction tools (C-statistics = 0.755 and 0.717, Brier scores = 0.158 and 0.178) outperformed healthcare professionals' discrimination, calibration and overall performance in predicting death. Two outcome prediction tools for ambulation (C-statistics = 0.688 and 0.667) marginally outperformed healthcare professionals. Conclusion: There is uncertainty in predicting 1-year outcomes following major lower limb amputation. Different professional groups performed comparably in this study. Two outcome prediction tools for death and two for ambulation outperformed healthcare professionals and may support shared decision-making
