Perspectives on implementing exercise bikes for use by inpatient mental health staff in the workplace: A qualitative study investigating staff attitudes
Authors: Martland Rebecca , Gaughran Fiona , Stubbs Brendon , Onwumere Juliana 
Published: April 2023

Accessible SummaryWhat is known on the subject?

Mental health nursing staff may experience psychological stress and burnout. Exercise provision for mental health staff may improve staff physical and mental wellbeing and mitigate against psychological burnout.

Existing research suggests the provision of exercise equipment for mental health nursing staff may improve staff attitudes towards physical activity and staff confidence in motivating physical activity amongst patient groups they care for, although more research is needed, and research investigating the attitudes of mental health staff towards such initiatives is warranted.

What this paper adds to existing knowledge?

Access to fitness facilities in the workplace for mental health staff was endorsed.

Logistical and practical concerns (i.e. shower access, time) were noted as barriers to implementation of fitness facilities in the workplace for staff use.

Mental health staff expressed desire to have access to varied gym equipment at work

What are the implications for practice?

The introduction of fitness facilities in the workplace environment for staff use was actively endorsed by mental health professionals, suggesting such initiatives may be warranted in mental health settings. However, barriers to successful implementation were noted and are worth considering in preparation for trialling provision of exercise equipment for staff use.

AbstractIntroductionExercise equipment for mental health staff may improve staff wellbeing, mitigate against stress and improve staff attitudes towards physical activity. This said, there is a lack of researching investigating the attitudes of mental health staff towards the provision of fitness facilities in the workplace.AimThe study investigated staff attitudes towards being offered exercise bikes in the workplace.MethodThree focus groups and one individual interview were conducted with 12 healthcare professionals. Data were subject to a thematic analysis.ResultsThree themes were identified. (1) ‘This sounds like a good idea’, which reflected positive views in the provision of exercise in the workplace for staff use. (2) ‘I'm not sure it would work because …’, which reflected implementation concerns including not having access to shower facilities and time constraints. (3) ‘Balancing choice’, which reflected participant's desire to have access to varied gym equipment.DiscussionThe introduction of fitness facilities in the workplace for staff use was endorsed. However, implementation barriers were noted.Implications for PracticeThis research provides justification for the exploration of the feasibility and benefits of providing exercise equipment for mental health staff in the workplace but presents implementation barriers that are worth considering before trialling provision of exercise equipment.
Framework for cyber risk loss distribution of hospital infrastructure: Bond percolation on mixed random graphs approach
Authors: Chiaradonna Stefano , Jevtić Petar , Lanchier Nicolas 
Published: April 2023

AbstractNetworks like those of healthcare infrastructure have been a primary target of cyberattacks for over a decade. From just a single cyberattack, a healthcare facility would expect to see millions of dollars in losses from legal fines, business interruption, and loss of revenue. As more medical devices become interconnected, more cyber vulnerabilities emerge, resulting in more potential exploitation that may disrupt patient care and give rise to catastrophic financial losses. In this paper, we propose a structural model of an aggregate loss distribution across multiple cyberattacks on a prototypical hospital network. Modeled as a mixed random graph, the hospital network consists of various patient‐monitoring devices and medical imaging equipment as random nodes to account for the variable occupancy of patient rooms and availability of imaging equipment that are connected by bidirectional edges to fixed hospital and radiological information systems. Our framework accounts for the documented cyber vulnerabilities of a hospital's trusted internal network of its major medical assets. To our knowledge, there exist no other models of an aggregate loss distribution for cyber risk in this setting. We contextualize the problem in the probabilistic graph‐theoretical framework using a percolation model and combinatorial techniques to compute the mean and variance of the loss distribution for a mixed random network with associated random costs that can be useful for healthcare administrators and cybersecurity professionals to improve cybersecurity management strategies. By characterizing this distribution, we allow for the further utility of pricing cyber risk.

Published: April 2023

Abstract
New energy vehicles are an effective solution to solve the situation of carbon neutrality with carbon peaking in China. The power battery system is the key component of new energy vehicles, and its performance is directly related to the safety and cruising range. Since the performance of the battery system is affected by factors such as electrical contact stability, voltage and current characteristics, and temperature, its full life cycle performance cannot be comprehensively evaluated, resulting in inefficient prediction and protective measures. In this paper, the electrical contact stability was studied, and the evaluation index was proposed by calculating the volatility of the battery state equation. The parameters, including electrical contact stability, polynomial-based state of charge, state of health, state of consistency, and battery system temperature, constituted the performance matrix of the battery system. A comprehensive performance evaluation method for a power battery system based on dynamic weight is designed with normalized classification. Finally, the cyclic charge/discharge test experiment under the vibration state was carried out to verify the effectiveness of the method. The result showed that the method could characterize various functions and provide an intuitive and detailed evaluation for the safety prediction of a battery system.

Published: April 2023

Abstract
This paper explores the kinematic synthesis, design, and pilot experimental testing of a six-legged walking robotic platform able to traverse through different terrains. We aim to develop a structured approach to designing the limb morphology using a relaxed kinematic task with incorporated conditions on foot-environments interaction, specifically contact force direction and curvature constraints, related to maintaining contact. The design approach builds up incrementally starting with studying the basic human leg walking trajectory and then defining a “relaxed” kinematic task. The “relaxed” kinematic task consists only of two contact locations (toe-off and heel-strike) with higher-order motion task specifications compatible with foot-terrain(s) contact and curvature constraints in the vicinity of the two contacts. As the next step, an eight-bar leg image is created based on the “relaxed” kinematic task and incorporated within a six-legged walking robot. Pilot experimental tests explore if the proposed approach results in an adaptable behavior which allows the platform to incorporate different walking foot trajectories and gait styles coupled to each environment. The results suggest that the proposed “relaxed” higher-order motion task combined with the leg morphological properties and feet material allowed the platform to walk stably on the different terrains. Here we would like to note that one of the main advantages of the proposed method in comparison with other existing walking platforms is that the proposed robotic platform has carefully designed limb morphology with incorporated conditions on foot-environment interaction. Additionally, while most of the existing multilegged platforms incorporate one actuator per leg, or per joint, our goal is to explore the possibility of using a single actuator to drive all six legs of the platform. This is a critical step which opens the door for the development of future transformative technology that is largely independent of human control and able to learn about the environment through their own sensory systems.

ObjectiveThis study aimed to investigate the preferences regarding risks, benefits and other treatment attributes of patients with type 2 diabetes mellitus (T2DM) in China when selecting a second-line anti-hyperglycaemic medicine.MethodsA discrete choice experiment with hypothetical anti-hyperglycaemic medication profiles was performed using a face-to-face survey administered to patients with T2DM. The medication profile was described using seven attributes: treatment efficacy, hypoglycaemia risk, cardiovascular benefits, gastrointestinal (GI) adverse events, weight change, mode of administration and out-of-pocket cost. Participants chose between medication profiles by comparing attributes. Data were analysed using a mixed logit model with marginal willingness to pay (mWTP) and maximum acceptable risk (MAR) calculated. The preference heterogeneity within the sample was explored using a latent class model (LCM).ResultsA total of 3327 respondents from five major geographical regions completed the survey. Treatment efficacy, hypoglycaemia risk, cardiovascular benefits and GI adverse events were major concerns among the seven attributes measured. Weight change and mode of administration were of lesser concern. Regarding mWTP, respondents would pay ¥236.1 (US$36.6) for an anti-hyperglycaemic medication with an efficacy of 2.5% points reduction in HbA1c, while they were willing to accept a weight gain of 3 kg only if they received a compensation of ¥56.7 (US$8.8). Respondents were willing to accept a relatively large increase in hypoglycaemia risk (MAR=15.9%) to improve treatment efficacy from intermediate (1.0% points) to high (1.5% points). LCM identified the following four unobserved subgroups: trypanophobia, cardiovascular-benefits-focused, safety-focused and efficacy-focused and cost-sensitive.ConclusionPatients with T2DM prioritised free out-of-pocket costs, highest efficacy, no hypoglycaemia risk and cardiovascular benefits over weight change and mode of administration. There exists great preference heterogeneity among patients, which should be taken into account in healthcare decision-making processes.

Published: April 2023

IntroductionThe role of primary caregivers in setting the foundation for a child’s oral health throughout life is well recognised. Due to the dominant behaviour-based approach, research to date has mainly focused on exploring individual primary caregivers’ oral health knowledge and behaviours. A social science approach involving social practice theories moves beyond individual attitudes, behaviour and choices to offer a better understanding of the ways in which collective activity relates to health. This qualitative metasynthesis will involve an interpretive synthesis of data found in published qualitative literature from developed countries. The aim of the metasynthesis is to identify social practices in families from published qualitative research with caregivers on preschool children’s oral health.Methods and analysisThis is a protocol for qualitative metasynthesis. The following databases will be used: MEDLINE, EMBASE, Global Health and Dentistry & Oral Sciences Source (DOSS) using the web-based database search platform Ovid, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Scopus. The research team has determined search strategies by using relevant key terms. Qualitative studies published in English language on family factors related to preschool children (aged 0–5 years) from developed countries (2022 United Nations classification) will be included. Qualitative data analysis will involve thematic analysis of the reported factors influencing oral health of preschool children, from the perspective of social practice theory. Researchers will use NVivo software for organising and managing the data.Ethics and disseminationNo ethics approval is required, as this study does not involve human subjects. Findings will be disseminated through professional networks, conference presentations and submission to a peer-reviewed journal.

ObjectivesTo describe the rehabilitation services available for communication disorders in Sri Lanka and to estimate the adequacy of the services in provinces and districts of the country.SettingThe study considered government and private institutions, which provide rehabilitation services for communication disorders in Sri Lanka.ParticipantsInstitutions providing services of speech–language pathologists, audiologists and audiology technicians in Sri Lanka.Primary and secondary outcome measuresWe investigated the number of government hospitals and private institutions, which provide speech–language pathology and audiology services in Sri Lanka as the primary outcome measure. A number of speech–language pathologists, audiologists and audiology technicians working in the institutions were obtained from records and institution-based inquiries to identify the adequacy of the services in the country as the secondary outcome measure.ResultsOf the 647 government hospitals that provide free healthcare services in the country, 45 and 33 hospitals had speech and language therapy and audiology units, respectively. Government hospitals do not have audiologists but only have audiology technicians. The number of speech and language therapists and audiology technicians in the government sector per 100 000 population in the country was 0.44 and 0.18, respectively. There were wide variations in specialist to population ratio between districts. 77 private centres provide speech therapy services in 15 out of the 25 districts; 36 private centres provide audiological evaluations in 9 districts.ConclusionsThe number of specialist speech and language therapists and audiologists is not sufficient to provide adequate rehabilitation services for communications disorder for the Sri Lankan population. Not recruiting audiologists to the government sector affects the management of hearing impairment in the affected.

BackgroundRegular exercise training is an important factor in prevention of myocardial infarction (MI). However, little is known whether exercise engagement prior to MI is related to the magnitude of post-MI cardiac biomarker concentrations and clinical outcomes.ObjectivesWe tested the hypothesis that exercise engagement in the week prior MI is related to lower cardiac biomarker concentrations following ST-elevated MI (STEMI).MethodsWe recruited hospitalised STEMI patients and assessed the amount of exercise engagement in the 7 days preceding MI onset using a validated questionnaire. Patients were classified as ‘exercise’ if they performed any vigorous exercise in the week prior MI, or as ‘control’ if they did not. Post-MI peak concentrations of high-sensitive cardiac troponin T (peak-hs-cTnT) and creatine kinase (peak-CK) were examined. We also explored whether exercise engagement prior MI is related to the clinical course (duration of hospitalisation and incidence of in-hospital, 30-day and 6-month major adverse cardiac events (reinfarction, target vessel revascularisation, cardiogenic shock or death)).ResultsIn total, 98 STEMI patients were included, of which 16% (n=16) was classified as ‘exercise’, and 84% (n=82) as ‘control’. Post-MI peak-hs-cTnT and peak-CK concentrations were lower in the exercise group (941 (645–2925) ng/mL; 477 (346–1402) U/L, respectively) compared with controls (3136 (1553–4969) ng/mL, p=0.010; 1055 (596–2019) U/L, p=0.016, respectively). During follow-up, no significant differences were found between both groups.ConclusionEngagement in exercise is associated with lower cardiac biomarker peak concentrations following STEMI. These data could provide further support for the cardiovascular health benefits of exercise training.
On the impacts of higher tobacco taxes in Argentina: a computable general equilibrium approach
Authors: Cicowiez Martin , Cruces Guillermo , Falcone Guillermo , Puig Jorge 
Published: April 2023

ObjectivesWe analyse the employment effects of increasing tobacco taxation in Argentina by building a computable general equilibrium (CGE) model.MethodsIn line with recent changes in tobacco taxation in the country, the CGE model simulates an increase in excise tax on cigarettes.ResultsThe results show that even a substantial increase in tobacco taxation induces a zero-net change in overall employment in the economy when the newly raised tax revenues are spent by the government on education, health or public infrastructure. Increased tobacco taxes may shift jobs from tobacco-related sectors to other sectors of the economy, but the overall impact on the total number of jobs is negligible.ConclusionsThe widely documented positive effects of higher tobacco taxes (including a healthier population, more productive workers, savings from avoided costs of medical treatment for tobacco-related diseases, reductions in the number of new young smokers, among others) would far outweigh the nearly null effect of higher taxes on total net employment.

Published: April 2023

AbstractComputed tomography (CT) scans are used to evaluate the severity of lung involvement in patients affected by COVID-19 pneumonia. Here, we present an improved version of the LungQuant automatic segmentation software (LungQuantv2), which implements a cascade of three deep neural networks (DNNs) to segment the lungs and the lung lesions associated with COVID-19 pneumonia. The first network (BB-net) defines a bounding box enclosing the lungs, the second one (U-net$$_1$$

1

) outputs the mask of the lungs, and the final one (U-net$$_2$$

2

) generates the mask of the COVID-19 lesions. With respect to the previous version (LungQuantv1), three main improvements are introduced: the BB-net, a new term in the loss function in the U-net for lesion segmentation and a post-processing procedure to separate the right and left lungs. The three DNNs were optimized, trained and tested on publicly available CT scans. We evaluated the system segmentation capability on an independent test set consisting of ten fully annotated CT scans, the COVID-19-CT-Seg benchmark dataset. The test performances are reported by means of the volumetric dice similarity coefficient (vDSC) and the surface dice similarity coefficient (sDSC) between the reference and the segmented objects. LungQuantv2 achieves a vDSC (sDSC) equal to 0.96 ± 0.01 (0.97 ± 0.01) and 0.69 ± 0.08 (0.83 ± 0.07) for the lung and lesion segmentations, respectively. The output of the segmentation software was then used to assess the percentage of infected lungs, obtaining a Mean Absolute Error (MAE) equal to 2%.

Published: April 2023

This research examined how the interplay between spouses’ attachment orientations contributes to physiological responses to relational stress. Mixed-gender newlyweds ( N Wave 1 = 218 couples; N Wave 2 = 184 couples; N Wave 3 = 164 couples) discussed relationship conflicts during three laboratory sessions over the first 3–4 years of marriage. Individuals provided saliva samples to assess their cortisol levels before, during, and after each conflict, which reflected physiological responses to stress. Across all three waves, anxiously-attached individuals showed greater cortisol reactivity (via faster rates of cortisol change and/or more exaggerated changes in cortisol slope) in anticipation of conflicts, especially when they had an avoidantly-attached partner. Findings highlight the dyadic nature of spouses’ responses to relational stress.
