The implementation and impacts of the Comprehensive Care Standard in Australian acute care hospitals: a survey study.

BACKGROUND: Comprehensive care (CC) is becoming a widely acknowledged standard for modern healthcare as it has the potential to improve health service delivery impacting both patient-centred care and clinical outcomes. In 2019, the Australian Commission on Safety and Quality in Health Care mandated the implementation of the Comprehensive Care Standard (CCS). However, little is known about the implementation and impacts of the CCS in acute care hospitals. Our study aimed to explore care professionals' self-reported knowledge, experiences, and perceptions about the implementation and impacts of the CCS in Australian acute care hospitals. METHODS: An online survey using a cross-sectional design that included Australian doctors, nurses, and allied health professionals in acute care hospitals was distributed through our research team and organisation, healthcare organisations, and clinical networks using various methods, including websites, newsletters, emails, and social media platforms. The survey items covered self-reported knowledge of the CCS and confidence in performing CC, experiences in consumer involvement and CC plans, and perceptions of organisational support and impacts of CCS on patient care and health outcomes. Quantitative data were analysed using Rstudio, and qualitative data were analysed thematically using Nvivo. RESULTS: 864 responses were received and 649 were deemed valid responses. On average, care professionals self-reported a moderate level of knowledge of the CCS (median = 3/5) and a high level of confidence in performing CC (median = 4/5), but they self-reported receiving only a moderate level of organisational support (median = 3/5). Only 4% (n = 17) of respondents believed that all patients in their unit had CCS-compliant care plans, which was attributed to lack of knowledge, motivation, teamwork, and resources, documentation issues, system and process limitations, and environment-specific challenges. Most participants believed the CCS introduction improved many aspects of patient care and health outcomes, but also raised healthcare costs. CONCLUSION: Care professionals are confident in performing CC but need more organisational support. Further education and training, resources, multidisciplinary collaboration, and systems and processes that support CC are needed to improve the implementation of the CCS. Perceived increased costs may hinder the sustainability of the CCS. Future research is needed to examine the cost-effectiveness of the implementation of the CCS.

The Regulate your Sitting Time (RESIT) intervention for reducing sitting time in individuals with type 2 diabetes: findings from a randomised-controlled feasibility trial.

BACKGROUND: Reducing and breaking up sitting is recommended for optimal management of Type 2 diabetes mellitus (T2DM). Yet, there is limited evidence of interventions targeting these outcomes in individuals with this condition. The primary aim of this study was to assess the feasibility and acceptability of delivering and evaluating a tailored online intervention to reduce and break up sitting in adults with T2DM. METHODS: A mixed-methods two-arm randomised controlled feasibility trial was conducted in ambulatory adults with T2DM who were randomised 1:1 to the REgulate your SItting Time (RESIT) intervention or usual care control group. The intervention included online education, self-monitoring and prompt tools (wearable devices, smartphone apps, computer apps) and health coaching. Feasibility outcomes were recruitment, attrition, data completion rates and intervention acceptability. Measurements of device-assessed sitting (intended primary outcome for definitive trial), standing and stepping, and physical function, psychosocial health and wellbeing were taken at baseline, 3 months and 6 months. Individual semi-structured interviews were conducted at six-months (post intervention) to explore acceptability, feasibility and experiences of the trial and intervention using the Framework Method. RESULTS: Seventy participants aged 55 ± 11 years were recruited. Recruitment rate (proportion of eligible participants enrolled into the study) was 67% and participant retention rate at 6 months was 93% (n = 5 withdrawals). Data completion rates for daily sitting were 100% at baseline and ranged from 83 to 91% at 3 months and 6 months. Descriptive analysis demonstrated potential for the intervention to reduce device-measured sitting, which was 30.9 ± 87.2 and 22.2 ± 82.5 min/day lower in the intervention group at 3 and 6 months, respectively, compared with baseline. In the control group, sitting was 4.4 ± 99.5 and 23.7 ± 85.2 min/day lower at 3 and 6 months, respectively. Qualitative analysis identified three themes: reasons for participating in the trial, acceptability of study procedures, and the delivery and experience of taking part in the RESIT intervention. Overall, the measurement visits and intervention were acceptable to participants. CONCLUSIONS: This study demonstrated the feasibility and acceptability of the RESIT intervention and evaluation methods, supporting a future definitive trial. If RESIT is found to be clinically effective, this could lead to changes in diabetes healthcare with a focus on reducing sitting. TRIAL REGISTRATION: The trial was registered with ISRCTN (number ISRCTN14832389).

Physical activity alters the effect of genetic determinants of adiposity on hypertension among individuals of European ancestry in the UKB.

Hypertension is a leading risk factor for cardiovascular disease and is modulated by genetic variants. This study aimed to assess the effect of obesity genetic liability and physical activity on hypertension among European and African ancestry individuals within the UK Biobank (UKB). Participants were 230 115 individuals of European ancestry and 3239 individuals of African ancestry from UKB. Genetic liability for obesity were estimated using previously published data including genetic variants and effect sizes for body mass index (BMI), waist-hip ratio (WHR) and waist circumference (WC) using Plink software. The outcome was defined as stage 2 hypertension (systolic blood pressure ≥ 140 mmHg, diastolic blood pressure ≥90 mmHg, or the use of anti-hypertensive medications). The association between obesity genetic liability and the outcome was assessed across categories of self-reported physical activity using logistic regression. Among European ancestry participants, there was up to a 1.2 greater odds of hypertension in individuals with high genetic liability and low physical activity compared to individuals with low genetic liability and high physical activity (p < 0.001). In individuals engaging in low levels of physical activity compared with moderate/high physical activity, the effect of BMI genetic liability on hypertension was greater (p interaction = 0.04). There was no evidence of an association between obesity genetic liability and hypertension in individuals of African ancestry in the whole sample or within separate physical activity groups (p > 0.05). This study suggests that higher physical activity levels are associated with lower odds of stage 2 hypertension among European ancestry individuals who carry high genetic liability for obesity. This cannot be inferred for individuals of African ancestry, possibly due to the low African ancestry sample size within the UKB.

Workplace Productivity, Health and Wellbeing: Findings From a Cluster Randomised Controlled Trial of a Workplace Intervention to Reduce Sitting in Office Workers.

OBJECTIVE: The aim of the study was to evaluate the feasibility and potential effects of a workplace intervention to reduce and break up sitting. METHODS: Office workers were randomized in clusters to intervention ( n = 22) or control ( n = 22). The intervention included a height-adjustable workstation, education, computer prompt software, and line manager support. Outcomes included device-measured workplace sitting and ecological momentary assessed workplace productivity. Recruitment, retention, and data completion rates were assessed. RESULTS: Recruitment ( N = 44), retention (91%), and workplace sitting measurement rates demonstrated study feasibility. At 8 weeks, workplace sitting was 11% lower (95% CI: -20.71, -1.30) in the intervention group compared with control participants. Intervention participants were also more engaged, motivated, and productive while sitting ( P ≤ 0.016). CONCLUSIONS: It was feasible to implement and evaluate this office workplace intervention, with potential benefits on workplace sitting and ecological momentary assessed productivity.

Identification and information management of cognitive impairment of patients in acute care hospitals: An integrative review.

Objectives: Recognition of the cognitive status of patients is important so that care can be tailored accordingly. The objective of this integrative review was to report on the current practices that acute care hospitals use to identify people with cognitive impairment and how information about cognition is managed within the healthcare record as well as the approaches required and recommended by policies. Methods: Following Whittemore & Knafl's five-step method, we systematically searched Medline, CINAHL, and Scopus databases and various grey literature sources. Articles relevant to the programs that have been implemented in acute care hospitals regarding the identification of cognitive impairment and management of cognition information were included. The Mixed Methods Appraisal Tool and AACODS (Authority, Accuracy, Coverage, Objectivity, Date, Significance) Checklist were used to evaluate the quality of the studies. Thematic analysis was used to present and synthesise results. This review was pre-registered on PROSPERO ( CRD42022343577). Results: Twenty-two primary studies and ten government/industry publications were included in the analysis. Findings included gaps between practice and policy. Although identification of cognitive impairment, transparency of cognition information, and interaction with patients, families, and carers (if appropriate) about this condition were highly valued at a policy level, sometimes in practice, cognitive assessments were informal, patient cognition information was not recorded, and interactions with patients, families, and carers were lacking. Discussion: By incorporating cognitive assessment, developing an integrated information management system using information technology, establishing relevant laws and regulations, providing education and training, and adopting a national approach, significant improvements can be made in the care provided to individuals with cognitive impairment.

A mixed methods systematic review on the effects of arts interventions for children and young people at-risk of offending, or who have offended on behavioural, psychosocial, cognitive and offending outcomes: A systematic review.

Background: Young people who enter the justice system experience complex health and social needs, and offending behaviour is increasingly recognised as a public health problem. Arts interventions can be used with the aim of preventing or reducing offending or reoffending. Objectives: 1. To evaluate evidence on the effectiveness and impact of arts interventions on keeping children and young people safe from involvement in violence and crime. 2. To explore factors impacting the implementation of arts interventions, and barriers and facilitators to participation and achievement of intended outcomes. 3. To develop a logic model of the processes by which arts interventions might work in preventing offending behaviours. Search Methods: We searched AMED, Academic Search Complete; APA PsycInfo; CINAHL Plus; ERIC; SocIndex; SportDiscus, Medline, CENTRAL, Web of Science, Scopus, PTSDPubs and Performing Arts Periodicals Database, Sage, the US National Criminal Justice Reference Service, the Global Policing and British Library EThOS databases, and the National Police Library from inception to January 2023 without language restrictions. Selection Criteria: We included randomised and non-randomised controlled trials and quasi-experimental study designs. We included qualitative studies conducted alongside intervention trials investigating experiences and perceptions of participants, and offering insight into the barriers and facilitators to delivering and receiving arts interventions. We included qualitative and mixed methods studies focused on delivery of arts interventions. We included studies from any global setting. We included studies with CYP (8-25 years) who were identified as at-risk of offending behaviour (secondary populations) or already in the criminal justice system (tertiary populations). We included studies of interventions involving arts participation as an intervention on its own or alongside other interventions. Primary outcomes were: (i) offending behaviour and (ii) anti-pro-social behaviours. Secondary outcomes were: participation/attendance at arts interventions, educational attainment, school attendance and engagement and exclusions, workplace engagement, wellbeing, costs and associated economic outcomes and adverse events. Data Collection and Analysis: We included 43 studies (3 quantitative, 38 qualitative and 2 mixed methods). We used standard methodological procedures expected by The Campbell Collaboration. We used GRADE and GRADE CERQual to assess the certainty of and confidence in the evidence for quantitative and qualitative data respectively. Main Results: We found insufficient evidence from quantitative studies to support or refute the effectiveness of arts interventions for CYP at-risk of or who have offended for any outcome. Qualitative evidence suggested that arts interventions may lead to positive emotions, the development of a sense of self, successful engagement in creative practices, and development of positive personal relationships. Arts interventions may need accessible and flexible delivery and are likely to be engaging if they have support from staff, family and community members, are delivered by professional artists, involve culturally relevant activity, a youth focus, regularity and a sustainable strategy. We found limited evidence that a lack of advocacy, low funding, insufficient wider support from key personnel in adjacent services could act as barriers to success. Methodological limitations resulted in a judgement of very low confidence in these findings. Authors' Conclusions: We found insufficient evidence from quantitative studies to support or refute the effectiveness of arts interventions for CYP at-risk of offending or who have offended for any outcome. We report very low confidence about the evidence for understanding the processes influencing the successful design and delivery of arts interventions in this population of CYP and their impact on behavioural, psychosocial, cognitive and offending outcomes.

Pneumopericardium following severe thoracic trauma.

BACKGROUND: Traumatic pneumopericardium (PPC) is a rare clinical entity associated with chest trauma, resulting from a pleuropericardial connection in the presence of a pneumothorax, interstitial air tracking along the pulmonary perivascular sheaths from ruptured alveoli to the pericardium, or direct trachea-bronchial-pericardial communication.  Our objectives were to describe the modern management approach to PPC and to identify variables that could improve survival with severe thoracic injury. METHODS: We conducted a retrospective study of the trauma registry between 2015 and 2022 at a Level I verified adult trauma center for all patients with PPC. Demographics, injury patterns, and treatment characteristics were compared between blunt and penetrating trauma. This study focused on the management strategies and the physiologic status regarding PPC and the development of tension physiology. The main outcome measure was operative versus nonoperative management. RESULTS: Over a seven-year period, there were 46,389 trauma admissions, of which 488 patients had pneumomediastinum. Eighteen patients were identified with PPC at admission. Median age was 39.5 years (range, 18-77 years), predominantly male (n = 16, 89 %), Black (n = 12, 67 %), and the majority from blunt trauma (78 %). Half had subcutaneous emphysema on presentation while 39 % had recognizable pneumomediastinum on chest x-ray. Tube thoracostomy was the most common intervention in this cohort (89 %). Despite tube thoracostomy, tension PPC was observed in three patients, two mandating emergent pericardial windows for progression to tension physiology, and the remaining requiring reconstruction of a blunt tracheal disruption. The majority of PPC patients recovered with expectant management (83 %), and no deaths were directly related to PPC. CONCLUSIONS: Traumatic PPC is a rare radiographic finding with the majority successfully managed conservatively in a monitored ICU setting. These patients often have severe thoracic injury with concomitant injuries requiring thoracostomy alone; however, emergent surgical intervention may be required when PPC progresses to tension physiology to improve overall survival.

Interrupting sitting acutely attenuates cardiometabolic risk markers in South Asian adults living with overweight and obesity.

PURPOSE: This study examined the acute effects of interrupting sitting with light-intensity walking on postprandial cardiometabolic risk markers in South Asian adults. METHODS: South Asians with overweight/obesity (n = 19; body mass index [BMI] > 23 kg·m-2) and normal-weight (n = 8; BMI 18.0-22.9 kg·m-2) aged 48.8 ± 5.6 years completed two, 5-h conditions: (1) prolonged sitting (SIT), and (2) interrupted sitting with 5-min bouts of light-intensity walking every 30-min (INT-SIT). Blood samples and resting expired air samples were collected throughout each condition. Statistical analyses were completed using linear mixed models. RESULTS: In participants with overweight/obesity, postprandial glucose, triglycerides (TAG) and metabolic load index (MLI) over time were lower, whereas resting substrate utilisation and resting energy expenditure (REE) were higher, in INT-SIT than SIT (all p ≤ 0.05). Compared with SIT (0.18 [95% CI 0.13, 0.22] kcal.min-1), INT-SIT (0.23 [95% CI 0.18, 0.27] kcal.min-1) increased postprandial REE iAUC in participants with overweight/obesity (p = 0.04, d = 0.51). Postprandial TAG concentrations over time were lower in INT-SIT versus SIT (p = 0.01, d = 30) in normal-weight participants, with no differences in any other outcomes for this sample group. CONCLUSION: These findings suggest that interrupting sitting with 5-min bouts of light walking every 30-min acutely attenuates cardiometabolic risk markers among South Asians living with overweight/obesity, whereas limited effects may be seen in individuals with normal-weight.

A new measure of exercise adherence: the ATEMPT (Adherence To Exercise for Musculoskeletal Pain Tool).

OBJECTIVES: This study aimed to (1) develop a new measure of adherence to exercise for musculoskeletal (MSK) pain (Adherence To Exercise for Musculoskeletal Pain Tool: ATEMPT) based on previously conceptualised domains of exercise adherence, (2) report the content and structural validity, internal consistency, test-retest reliability, and measurement error for the ATEMPT outcome measure in patients managed with exercise for MSK pain. METHODS: ATEMPT was created using statements describing adherence generated by patients, physiotherapists and researchers, with content validity established. Baseline and retest questionnaires were distributed to patients recommended exercise for MSK pain in 11 National Health Service physiotherapy clinics. Items demonstrating low response variation were removed and the following measurement properties assessed: structural validity, internal consistency, test-retest reliability and measurement error. RESULTS: Baseline and retest data were collected from 382 and 112 patients with MSK pain, respectively. Confirmatory factor analysis established that a single factor solution was the best fit according to Bayesian Information Criterion. The 6-item version of the measure (scored 6-30) demonstrated optimal internal consistency (Cronbach's Alpha 0.86, 95% CI 0.83 to 0.88) with acceptable levels of test-retest reliability (intraclass correlation coefficient 0.84, 95% CI 0.78 to 0.88) and measurement error (smallest detectable change 3.77, 95% CI 3.27 to 4.42) (SE of measurement 2.67, 95% CI 2.31 to 3.16). CONCLUSION: The 6-item ATEMPT was developed from the six domains of exercise adherence. It has adequate content and structural validity, internal consistency, test-retest reliability and measurement error in patients with MSK pain, but should undergo additional testing to establish the construct validity and responsiveness.

Stress and Work Performance Responses to a Multicomponent Intervention for Reducing and Breaking up Sitting in Office Workers: A Cluster Randomized Controlled Trial.

OBJECTIVE: The aim of the study is to explore the potential of a sitting reduction workplace intervention for improving stress and work performance. METHODS: A cluster randomized controlled trial evaluated an intervention to reduce and break up occupational sitting in 12 clusters ( n = 89 office workers) over 8 weeks. Outcomes were physiological stress (cortisol concentrations), perceived stress, and work performance. RESULTS: Linear mixed model group × time interaction effects were nonsignificant. Exploratory analyses showed a trend, with a large effect, for lower cortisol concentrations over the day in the intervention group relative to controls at 8 weeks (-0.85; 95% confidence interval, -1.70 to 0.03 nmol·L -1 ; P = 0.06, d = 0.79). The intervention group had higher vigor and cognitive liveliness at 8 weeks relative to controls ( P ≤ 0.05). CONCLUSIONS: This exploratory study suggests that there could be meaningful changes in physiological stress and work-related outcomes that should be investigated in future studies.

Monkeypox virus-infected individuals mount comparable humoral immune responses as Smallpox-vaccinated individuals.

In early 2022, a cluster of monkeypox virus (MPXV) infection (mpox) cases were identified within the UK with no prior travel history to MPXV-endemic regions. Subsequently, case numbers exceeding 80,000 were reported worldwide, primarily affecting gay, bisexual, and other men who have sex with men (GBMSM). Public health agencies worldwide have offered the IMVANEX Smallpox vaccination to these individuals at high-risk to provide protection and limit the spread of MPXV. We have developed a comprehensive array of ELISAs to study poxvirus-induced antibodies, utilising 24 MPXV and 3 Vaccinia virus (VACV) recombinant antigens. Panels of serum samples from individuals with differing Smallpox-vaccine doses and those with prior MPXV infection were tested on these assays, where we observed that one dose of Smallpox vaccination induces a low number of antibodies to a limited number of MPXV antigens but increasing with further vaccination doses. MPXV infection induced similar antibody responses to diverse poxvirus antigens observed in Smallpox-vaccinated individuals. We identify MPXV A27 as a serological marker of MPXV-infection, whilst MPXV M1 (VACV L1) is likely IMVANEX-specific. Here, we demonstrate analogous humoral antigen recognition between both MPXV-infected or Smallpox-vaccinated individuals, with binding to diverse yet core set of poxvirus antigens, providing opportunities for future vaccine (e.g., mRNA) and therapeutic (e.g., mAbs) design.

Acute Cardiometabolic and Exercise Responses to Breakfast Omission Versus Breakfast Consumption in Adolescent Girls: A Randomised Crossover Trial.

Girls often begin to skip breakfast during adolescence. This study compared the acute effect of breakfast omission versus consumption on cardiometabolic risk markers and perceived appetite and mood during rest and/or exercise in adolescent girls classified as habitual breakfast consumers. Girls (aged 13.2 ± 0.7 years) completed two 5.5 h conditions in a randomised crossover design: breakfast omission (BO) and standardised breakfast consumption (BC). A standardised lunch was provided at 3 h. Incremental cycling exercise was performed at 5 h. Blood and expired gas samples were taken at regular intervals. Whilst pre-lunch plasma glucose, insulin, and Metabolic Load Index incremental area under the curve (IAUC) were significantly lower in BO versus BC, post-lunch differences were reversed and larger in magnitude. Peak plasma glucose and insulin were significantly higher in BO versus BC. Pre-lunch perceived fullness and hunger were significantly lower and higher, respectively, in BO versus BC. Perceived energy and concentration were lower, and tiredness was higher, in BO versus BC. Exercise peak fat oxidation and Fatmax were unaffected. The lower physical activity enjoyment in BO versus BC approached significance. To conclude, acutely omitting breakfast adversely affects cardiometabolic risk markers and exercise enjoyment among adolescent girls who habitually consume breakfast.

PROTOCOL: A mixed methods systematic review on the effects of arts interventions for at-risk and offending children and young people on behavioural, psychosocial, cognitive and offending outcomes.

This is the protocol for a Campbell systematic review. The proposed systematic review question is: What is the effectiveness of arts interventions for at-risk and offending children and young people (8-25 years)? There are three objectives: (1) To evaluate evidence on the effectiveness and impact of arts interventions on keeping children safe from involvement in violence and crime; (2) To synthesise evidence on factors impacting the implementation of arts interventions, and barriers and facilitators to participation and achievement of intended outcomes; (3) To develop a theory-of-change approach to ensure the development of an evidence-led framework of the processes by which arts interventions might work in preventing offending behaviours.

Evaluation of Sleep Quality and Its Relationship With Pain, Mood, and Physical Function After Orthopaedic Trauma Surgery: A Prospective Cohort Study.

INTRODUCTION: Sleep disturbances are associated with pain and mental health. We prospectively compared a cohort of patients with orthopaedic trauma with a control group to establish the prevalence and duration of sleep disturbance and associations between sleep disturbance and pain, mood scores, and functional outcome scores. METHODS: Subjects were patients with orthopaedic trauma undergoing in-patient surgical procedures and healthy control subjects from the community. Questionnaires completed by all subjects included the VAS numerical pain rating scale, the abbreviated profile of mood states, Patient-Reported Outcomes Measurement Information System Physical Function, and Patient-Reported Outcomes Measurement Information System Sleep Disturbance. Control subjects completed the surveys once, and subjects with trauma completed them at 2, 6, and 24 weeks postoperatively. RESULTS: Healthy control subjects (28.6 ± 13.2) were significantly younger than patients with trauma (41.8 ± 18.9) ( P < 0.001). Compared with control subjects, at 2-week follow-up visit, patients with trauma had worse sleep ( P < 0.001) and worse mood ( P = 0.006). Across the study period, patients with trauma showed improvements in physical function ( P < 0.001) and pain (at rest [ P = 0.02], during activity [ P = 0.02], and at night [ P = 0.002]). In patients with trauma, better sleep disturbance scores were associated with better mood and less pain for all pain metrics ( P < 0.001). DISCUSSION: Patients with orthopaedic trauma have worse sleep disturbance scores at 2 weeks postoperatively compared with normal control subjects; this difference attenuated at 6 weeks. Sleep disturbance was found to markedly correlate with pain and mood, with worse sleep quality associated with higher pain and worse mood. Improvement in sleep quality across 24 weeks postoperatively was associated with improvement in mood scores. CONCLUSION: Patients should be counseled about the likely development of sleep disturbance and the possible association with worse emotional/mental health with worse sleep. Physicians should consider incorporating a multidisciplinary approach to the management of these select patients.

High- Versus Low-Energy Intertrochanteric Hip Fractures in Young Patients: Injury Characteristics and Factors Associated With Complications.

OBJECTIVE: To compare fracture patterns and associated injuries for young patients with high- versus low-energy intertrochanteric hip fractures and to report on factors associated with complications after surgical fixation of high-energy fractures. DESIGN: Retrospective comparative study. SETTING: Academic Level 1 Trauma Center. PATIENTS: A total of 103 patients 50 years of age or younger were included: 80 high-energy fractures and 23 low-energy fractures. INTERVENTION: Cephalomedullary nailing (N = 92) or a sliding hip screw (N = 11). MAIN OUTCOME MEASURES: Radiographic characteristics of fracture morphology, implant position, and reduction quality and postoperative complications were the main outcome measures. RESULTS: Compared with young patients with low-energy fractures, those with high-energy fractures had more fracture comminution ( P = 0.013) and higher ISS scores ( P < 0.003) and were more likely to require open reduction ( P < 0.001). Patients with low-energy fractures from a ground-level fall had higher rates of alcohol abuse (0.032), cirrhosis (0.010), and chronic steroid use (0.048). Overall reoperation rate for high-energy fractures was 7%, including 2 IT fracture nonunions (5%) and 1 deep infection (2%). For high-energy fractures, ASA class ( P = 0.026), anterior lag screw position ( P = 0.001), and varus malreduction ( P < 0.001) were associated with malunion. Four-part fracture (OTA/AO 31A2.3/Jensen 5) ( P = 0.028) and residual calcar gap >3 mm ( P = 0.03) were associated with reoperation. CONCLUSIONS: Surgical treatment of high-energy IT fractures in young patients is technically demanding with potential untoward outcomes. Injury characteristics and severity are significantly different for young patients with high-energy IT fractures compared with low-energy fractures. For young patients with a high-energy IT fracture, surgeons can anticipate a high rate of associated injuries and complex fracture patterns requiring open reduction. For young patients with a low-energy IT fracture, comanagement with a hospitalist or a geriatrician should be considered because they may be physiologically older. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

'Building back better' or sustaining the unsustainable? The climate impacts of Bank of England QE in the Covid-19 pandemic.

The environmental impacts of monetary policy received academic attention after the 2008 financial crisis and the 'market neutral' quantitative easing policies that followed. This article examines the Bank of England's Corporate Covid Financing Facility (CCFF) and the Asset Purchasing Facility (APF) between June 2020 and June 2021 to assess whether the Bank's response to the COVID-19 pandemic was aligned with the transition to sustainability. The data indicates that the Bank of England's monetary allocation schemes again served as a panacea for businesses with ecologically intensive business models and a Treasury committed to restoring the pre-existing growth model. Indeed, the Bank's QE schemes now represents an element of the crisis management governance that repeatedly 'locks in' the ecologically-calamitous economic trajectory at potential critical junctures. The Bank's shielding of its technocratic and depoliticised status has thus far inhibited any leadership role in tackling the climate crisis, despite its growing power as an actor of economic governance at times of crisis and purported enthusiasm to 'build back better'.

Breaking up sitting with short frequent or long infrequent physical activity breaks does not lead to compensatory changes in appetite, appetite-regulating hormones or energy intake.

The aim of this study was to determine the appetite-related responses to breaking up prolonged sitting with physical activity bouts differing in frequency and duration among adult females. Fourteen sedentary females aged 34 ± 13 years with a body mass index of 27.1 ± 6.3 kg/m2 (mean ± SD) took part in a randomised crossover trial with three, 7.5 h conditions: (1) uninterrupted sitting (SIT), (2) sitting with short frequent 2-min moderate-intensity walking breaks every 30 min (SHORT-BREAKS), and (3) sitting with longer duration, less frequent 10-min moderate-intensity walking breaks every 170-180 min (LONG-BREAKS). The intensity and total duration of physical activity was matched between the SHORT-BREAKS and LONG-BREAKS conditions. Linear mixed models were used to compare the outcomes between conditions with significance being accepted as p ≤ 0.05. There were no significant between-condition differences in hunger, satisfaction, prospective food consumption or overall appetite area under the curve (AUC) (all p ≥ 0.801). Absolute ad libitum energy intake and relative energy intake (REI) did not differ significantly between conditions (all p ≥ 0.420). Acylated ghrelin and total peptide YY incremental and total AUC did not differ significantly between conditions (all p ≥ 0.388). Yet, there was a medium effect size for the higher acylated ghrelin incremental AUC in SHORT-BREAKS versus SIT (d = 0.61); the reverse was seen for total AUC, which was lower in SHORT-BREAKS versus SIT (d = 0.69). These findings suggest that breaking up sitting does not lead to compensatory changes in appetite, appetite hormones or energy intake regardless of physical activity bout duration and frequency among adult females.

The Frail-LESS (LEss Sitting and Sarcopenia in Frail older adults) intervention to improve sarcopenia and maintain independent living via reductions in prolonged sitting: a randomised controlled feasibility trial protocol.

BACKGROUND: Sarcopenia is a progressive and generalised loss of muscle mass and function with advancing age and is a major contributor to frailty. These conditions lead to functional disability, loss of independence, and lower quality of life. Sedentary behaviour is adversely associated with sarcopenia and frailty. Reducing and breaking up sitting should thus be explored as an intervention target for their management. The primary aim of this study, therefore, is to examine the feasibility, safety, and acceptability of conducting a randomised controlled trial (RCT) that evaluates a remotely delivered intervention to improve sarcopenia and independent living via reducing and breaking up sitting in frail older adults. METHODS: This mixed-methods randomised controlled feasibility trial will recruit 60 community-dwelling older adults aged ≥ 65 years with very mild or mild frailty. After baseline measures, participants will be randomised to receive the Frail-LESS (LEss Sitting and Sarcopenia in Frail older adults) intervention or serve as controls (usual care) for 6 months. Frail-LESS is a remotely delivered intervention comprising of tailored feedback on sitting, information on the health risks of excess sitting, supported goal setting and action planning, a wearable device that tracks inactive time and provides alerts to move, health coaching, and peer support. Feasibility will be assessed in terms of recruitment, retention and data completion rates. A process evaluation will assess intervention acceptability, safety, and fidelity of the trial. The following measures will be taken at baseline, 3 months, and 6 months: sitting, standing, and stepping using a thigh-worn activPAL4 device, sarcopenia (via hand grip strength, muscle mass, and physical function), mood, wellbeing, and quality of life. DISCUSSION: This study will determine the feasibility, safety, and acceptability of evaluating a remote intervention to reduce and break up sitting to support improvements in sarcopenia and independent living in frail older adults. A future definitive RCT to determine intervention effectiveness will be informed by the study findings.

Infections in travellers returning to the UK: a retrospective analysis (2015-2020).

BACKGROUND: Every year, many thousands of travellers return to the United Kingdom (UK) from visits to other countries and some will become unwell due to infections acquired abroad. Many imported infections have similar clinical presentations, such as fever and myalgia, so diagnostic testing is an important tool to improve patient management and outcomes. The aim of this study was to examine the demographics, travel history, presenting symptoms and diagnostic outcomes of referrals to the UK's specialist diagnostic Rare & Imported Pathogens Laboratory (RIPL) for the period 2015-2020. METHODS: Anonymised clinical and laboratory data were extracted from RIPL's Laboratory Information Management System and cleaned prior to descriptive analysis of the data. Travel history data were mapped to one of eight world regions, whereas symptom data were categorised into presenting syndromes. Diagnostic data were categorised as either positive, equivocal or negative. RESULTS: During the period 2015-2020, RIPL received 73 951 samples from 53 432 patients suspected of having infections that are rare in the UK. The most common age group for unwell returning travellers was 30-39 years and the most commonly reported travel destination was Southern and SE Asia. Dengue virus was the most diagnosed infection overall, followed by chikungunya, Zika, leptospirosis and spotted fever group Rickettsia. Dengue virus was among the top three most frequent diagnoses for all world regions except Europe and represented 62.5% of all confirmed/probable diagnoses. CONCLUSIONS: None of the top five infections diagnosed by RIPL in travellers are vaccine-preventable, therefore understanding traveller demographics, destination-specific risk factors and encouraging preventative behaviours is the best available strategy to reduce the number of returning travellers who become infected. Prompt referral of acute samples with a detailed travel history, including purpose of travel and activities undertaken as well as dates and destinations can be a valuable tool in designing public health interventions and diagnostic algorithms.
