RESUMEN
BACKGROUND: There is little consensus on using statins for primary prevention of cardiovascular diseases (CVDs) and all-cause mortality in adults aged 75 years or older due to the underrepresentation of this population in randomized controlled trials. OBJECTIVE: To investigate the benefits and risks of using statins for primary prevention in old (aged 75 to 84 years) and very old (aged ≥85 years) adults. DESIGN: Sequential target trial emulation comparing matched cohorts initiating versus not initiating statin therapy. SETTING: Territory-wide public electronic medical records in Hong Kong. PARTICIPANTS: Persons aged 75 years or older who met indications for statin initiation from January 2008 to December 2015 were included. Participants with preexisting diagnosed CVDs at baseline, such as coronary heart disease (CHD), were excluded from the analysis. Among 69 981 eligible persons aged 75 to 84 years and 14 555 persons aged 85 years or older, 41 884 and 9457 had history of CHD equivalents (for example, diabetes) in the respective age groups. INTERVENTION: Initiation of statin therapy. MEASUREMENTS: Incidence of major CVDs (stroke, myocardial infarction, or heart failure), all-cause mortality, and major adverse events (myopathies and liver dysfunction). RESULTS: Of 42 680 matched person-trials aged 75 to 84 years and 5390 matched person-trials aged 85 years or older (average follow-up, 5.3 years), 9676 and 1600 of them developed CVDs in each age group, respectively. Risk reduction for overall CVD incidence was found for initiating statin therapy in adults aged 75 to 84 years (5-year standardized risk reduction, 1.20% [95% CI, 0.57% to 1.82%] in the intention-to-treat [ITT] analysis; 5.00% [CI, 1.11% to 8.89%] in the per protocol [PP] analysis) and in those aged 85 years or older (ITT: 4.44% [CI, 1.40% to 7.48%]; PP: 12.50% [CI, 4.33% to 20.66%]). No significantly increased risks for myopathies and liver dysfunction were found in both age groups. LIMITATION: Unmeasured confounders, such as lifestyle factors of diet and physical activity, may exist. CONCLUSION: Reduction for CVDs after statin therapy were seen in patients aged 75 years or older without increasing risks for severe adverse effects. Of note, the benefits and safety of statin therapy were consistently found in adults aged 85 years or older.

In the Emergency Department, patients with suspected myocardial infarction can be risk stratified using the HEART pathway, which has recently been amended for prehospital use and modified for the incorporation of a high-sensitivity cardiac troponin test. In a prospective analysis, the performance of both HEART pathways in the prehospital setting, with a high-sensitivity cardiac troponin test using 3 different thresholds, was evaluated for major adverse cardiac events at 30 days. We found that both low-risk HEART pathways, when using the most conservative cardiac troponin thresholds, approached but did not reach accepted rule-out performance in the Emergency Department.

The ability to treat severe viral infections is limited by our understanding of the mechanisms behind virus-induced immunopathology. While the role of type I interferons (IFNs) in early control of viral replication is clear, less is known about how IFNs can regulate the development of immunopathology and affect disease outcomes. Here, we report that absence of type I IFN receptor (IFNAR) is associated with extensive immunopathology following mucosal viral infection. This pathology occurred independent of viral load or type II immunity but required the presence of macrophages and IL-6. The depletion of macrophages and inhibition of IL-6 signaling significantly abrogated immunopathology. Tissue destruction was mediated by macrophage-derived matrix metalloproteinases (MMPs), as MMP inhibition by doxycycline and Ro 28-2653 reduced the severity of tissue pathology. Analysis of post-mortem COVID-19 patient lungs also displayed significant upregulation of the expression of MMPs and accumulation of macrophages. Overall, we demonstrate that IFNs inhibit macrophage-mediated MMP production to prevent virus-induced immunopathology and uncover MMPs as a therapeutic target towards viral infections.

BACKGROUND: Affordability of healthy food is a key determinant of the diet-related health of First Nations Peoples. This systematic scoping review was commissioned by the Ngaanyatjarra Pitjantjatjara Yankunytjatjara Women's Council (NPYWC) in Central Australia to identify interventions to improve economic access to healthy food in First Nations communities in selected high-income, colonised countries. METHODS: Eight databases and 22 websites were searched to identify studies of interventions and policies to improve economic access to healthy food in First Nations communities in Australia, Canada, the United States or New Zealand from 1996 to May 2022. Data from full text of articles meeting inclusion criteria were extracted to a spreadsheet. Results were collated by descriptive synthesis. Findings were examined with members of the NPYWC Anangu research team at a co-design workshop. RESULTS: Thirty-five publications met criteria for inclusion, mostly set in Australia (37%) or the US (31%). Interventions (n = 21) were broadly categorised as price discounts on healthy food sold in communities (n = 7); direct subsidies to retail stores, suppliers and producers (n = 2); free healthy food and/or food vouchers provided to community members (n = 7); increased financial support to community members (n = 1); and other government strategies (n = 4). Promising initiatives were: providing a box of food and vouchers for fresh produce; prescriptions for fresh produce; provision/promotion of subsidised healthy meals and snacks in community stores; direct funds transfer for food for children; offering discounted healthy foods from a mobile van; and programs increasing access to traditional foods. Providing subsidies directly to retail stores, suppliers and producers was least effective. Identified enablers of effective programs included community co-design and empowerment; optimal promotion of the program; and targeting a wide range of healthy foods, particularly traditional foods where possible. Common barriers in the least successful programs included inadequate study duration; inadequate subsidies; lack of supporting resources and infrastructure for cooking, food preparation and storage; and imposition of the program on communities. CONCLUSIONS: The review identified 21 initiatives aimed at increasing affordability of healthy foods in First Nations communities, of which six were deemed promising. Five reflected the voices and experiences of members of the NPYWC Anangu research team and will be considered by communities for trial in Central Australia. Findings also highlight potential approaches to improve economic access to healthy foods in First Nations communities in other high-income colonised countries.

OBJECTIVE: To develop and examine the measurement properties and interpretability of the Mobility Scale for "All" Stroke Phases (MSAllS) as a potential single outcome measure to capture improvements in physical function throughout the stroke continuum. DESIGN: Retrospective cross-sectional study. SETTING: Inpatient rehabilitation unit. PARTICIPANTS: People after stroke at discharge from rehabilitation (N=309). INTERVENTION: Not applicable. MAIN OUTCOME MEASURE(S): We developed MSAllS by extending the highest MSAS level (walk 10 m independently) with 4 gait speed levels. To establish a clinical anchor, we extracted a 4-level discharge outcome. To assess the distributional properties and internal consistency of MSAllS, we evaluated its ceiling effects and calculated the Cronbach alpha, respectively. To assess structural validity, we performed a confirmatory factor analysis. To assess (i) its convergent validity with the FIM and (ii) its predictive validity with the clinical anchor, we used Spearman's rank correlations. To evaluate the clinical interpretability of MSAllS, we used an item-response theory-based method to estimate MSAllS thresholds associated with the clinical anchor. RESULTS: The MSAllS had lower ceiling effects compared with MSAS (0% vs 25%). Internal consistency of MSAllS was excellent (α=0.94). Structural validity of MSAllS demonstrated a good fit (Comparative Fit Index=0.95; Tucker-Lewis Index=0.92; Root Means Square Error of Approximation=0.17). MSAllS demonstrated a moderate correlation (rho=0.66) with FIM score and with the clinical anchor (rho=0.75). MSAllS thresholds for increasing levels of the clinical anchor were 22 (20.8 to 23.6) - at least moderate assistance with walking/transfers, 28 (27.5 to 29.4) - at most supervision with walking, and 33 (32.5 to 33.4) - able to walk unassisted. CONCLUSION: The MSAllS showed adequate measurement properties and clinical interpretability. MSAllS has the potential to be a single universal measure to evaluate physical function after stroke but further evaluation of clinical interpretability is required.

BACKGROUND: Environmental factors can impact the ability of food retail businesses to implement best practice health-enabling food retail. METHODS: We co-designed a short-item survey on factors influencing food retail health-enabling practice in a remote Australian setting. Publicly available submissions to an Australian Parliamentary Inquiry into food pricing and food security in remote Indigenous communities were coded using an existing remote community food systems assessment tool and thematically analysed. Themes informed survey questions that were then prioritised, refined and pre-tested with expert stakeholder input. RESULTS: One-hundred and eleven submissions were coded, and 100 themes identified. Supply chain related data produced the most themes (n = 25). The resulting 26-item survey comprised questions to assess the perceived impact of environmental factors on a store's health-enabling practice (n = 20) and frequency of occurrence (n = 6). CONCLUSIONS: The application of this evidence-informed, co-designed survey will provide a first-time cross-sectional analysis and the potential for ongoing longitudinal data and advocacy on how environmental factors affect the operations of remote stores.

BACKGROUND: Aboriginal and Torres Strait Islander communities in remote Australia have initiated bold policies for health-enabling stores. Benchmarking, a data-driven and facilitated 'audit and feedback' with action planning process, provides a potential strategy to strengthen and scale health-enabling best-practice adoption by remote community store directors/owners. We aim to co-design a benchmarking model with five partner organisations and test its effectiveness with Aboriginal and Torres Strait Islander community stores in remote Australia. METHODS: Study design is a pragmatic randomised controlled trial with consenting eligible stores (located in very remote Northern Territory (NT) of Australia, primary grocery store for an Aboriginal community, and serviced by a Nutrition Practitioner with a study partner organisation). The Benchmarking model is informed by research evidence, purpose-built best-practice audit and feedback tools, and co-designed with partner organisation and community representatives. The intervention comprises two full benchmarking cycles (one per year, 2022/23 and 2023/24) of assessment, feedback, action planning and action implementation. Assessment of stores includes i adoption status of 21 evidence-and industry-informed health-enabling policies for remote stores, ii implementation of health-enabling best-practice using a purpose-built Store Scout App, iii price of a standardised healthy diet using the Aboriginal and Torres Strait Islander Healthy Diets ASAP protocol; and, iv healthiness of food purchasing using sales data indicators. Partner organisations feedback reports and co-design action plans with stores. Control stores receive assessments and continue with usual retail practice. All stores provide weekly electronic sales data to assess the primary outcome, change in free sugars (g) to energy (MJ) from all food and drinks purchased, baseline (July-December 2021) vs July-December 2023. DISCUSSION: We hypothesise that the benchmarking intervention can improve the adoption of health-enabling store policy and practice and reduce sales of unhealthy foods and drinks in remote community stores of Australia. This innovative research with remote Aboriginal and Torres Strait Islander communities can inform effective implementation strategies for healthy food retail more broadly.

AIMS: This study aimed to investigate the experiences and transitional care needs of Turkish frail older adults living in the UK and determine how this information can be utilized to improve the provision of culturally sensitive care during the transitional period. DESIGN: Qualitative descriptive research with semi-structured individual interviews. METHODS: "The 'Silences' Framework guided the research design, from conceptualizing the research question to structuring the report of final outputs. For this study, semi-structured, in-depth interviews were conducted with sixteen older adults living with frailty and five family caregivers between January and May of 2023 in the United Kingdom. RESULTS: Major themes that were identified included: (i) information and communication, (ii) care and support, (iii) the role of culture and (iv) trust and satisfaction. Further analysis, through discussion and immersion in the data, revealed that care transition periods were presented alongside three phases of transitional care: pre-transition (during hospitalization), early-transition (the period between discharge and the 7th day after discharge) and late transition (the period between the 8th day and 12th month after discharge). CONCLUSIONS: Our study revealed that the communication and informational needs of frail older individuals change during the transition period. While Turkish older adults and family caregivers expressed satisfaction with healthcare services in the UK, many struggled due to a lack of knowledge on how to access them. IMPACT: The support of family caregivers is a crucial component in facilitating transitional care for frail older patients, as they help in accessing healthcare services and using technological devices or platforms. It should be noted that family caregivers often hold the same level of authority as their elderly Turkish counterparts. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

BACKGROUND: UK examining bodies are required to eliminate discrimination against people with protected characteristics. To achieve this in surgery, differential attainment (DA) in assessments used as gatekeepers to career progression must be ruled out. This study investigated the impact of disability status on the likelihood of success at national selection for Higher Surgical Training (HST). METHODS: A retrospective cohort study of all UK graduates in the UKMED database (https://www.ukmed.ac.uk) who underwent selection for HST (ST3) from 2012 to 2019 (n = 2875). Univariate analysis identified differences in success rates at first-application. Logistic regression models identified whether disability was a predictor of success after adjusting for sociodemographic factors and prior MRCS performance. RESULTS: There was no significant difference in success rates between candidates with and without disabilities (all p > 0.05) for any surgical specialty. Disability status was not a statistically significant predictor of success. Female candidates were 25 % more likely to be successful (OR 1.25 [95%CI 1.05 to 1.49]) and Non-White candidates were 20 % less likely to be successful (OR 0.80 [95%CI 0.68 to 0.96]). Candidates who passed MRCS Part A and Part B at the first attempt were 49 % (OR 1.49 [95%CI 1.25 to 1.77]) and 90 % (OR 1.90 [95%CI 1.58 to 2.28]) more likely to be successful. CONCLUSION: No significant difference was found in the likelihood of being successful at HST selection for any surgical specialty between applicants with and without disabilities, regardless of type of disability. DA was identified between other sociodemographic groups which requires further exploration.
RESUMEN
Importance: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. Observational studies report that ß-blocker use may be associated with reduced risk of COPD exacerbations. However, a recent trial reported that metoprolol did not reduce COPD exacerbations and increased COPD exacerbations requiring hospital admission. Objective: To test whether bisoprolol decreased COPD exacerbations in people with COPD at high risk of exacerbations. Design, Setting, and Participants: The Bisoprolol in COPD Study (BICS) was a double-blind placebo-controlled randomized clinical trial conducted in 76 UK sites (45 primary care clinics and 31 secondary clinics). Patients with COPD who had at least moderate airflow obstruction on spirometry (ratio of forced expiratory volume in the first second of expiration [FEV1] to forced vital capacity <0.7; FEV1 <80% predicted) and at least 2 COPD exacerbations treated with oral corticosteroids, antibiotics, or both in the prior 12 months were enrolled from October 17, 2018, to May 31, 2022. Follow-up concluded on April 18, 2023. Interventions: Patients were randomly assigned to bisoprolol (n = 261) or placebo (n = 258). Bisoprolol was started at 1.25 mg orally daily and was titrated as tolerated during 4 sessions to a maximum dose of 5 mg/d, using a standardized protocol. Main Outcomes and Measures: The primary clinical outcome was the number of patient-reported COPD exacerbations treated with oral corticosteroids, antibiotics, or both during the 1-year treatment period. Safety outcomes included serious adverse events and adverse reactions. Results: Although the trial planned to enroll 1574 patients, recruitment was suspended from March 16, 2020, to July 31, 2021, due to the COVID-19 pandemic. Two patients in each group were excluded postrandomization. Among the 515 patients (mean [SD] age, 68 [7.9] years; 274 men [53%]; mean FEV1, 50.1%), primary outcome data were available for 514 patients (99.8%) and 371 (72.0%) continued taking the study drug. The primary outcome of patient-reported COPD exacerbations treated with oral corticosteroids, antibiotics, or both was 526 in the bisoprolol group, with a mean exacerbation rate of 2.03/y, vs 513 exacerbations in the placebo group, with a mean exacerbation rate of 2.01/y. The adjusted incidence rate ratio was 0.97 (95% CI, 0.84-1.13; P = .72). Serious adverse events occurred in 37 of 255 patients in the bisoprolol group (14.5%) vs 36 of 251 in the placebo group (14.3%; relative risk, 1.01; 95% CI, 0.62-1.66; P = .96). Conclusions and Relevance: Among people with COPD at high risk of exacerbation, treatment with bisoprolol did not reduce the number of self-reported COPD exacerbations requiring treatment with oral corticosteroids, antibiotics, or both.

ABSTRACT: This article describes an infant who developed a facial rash within minutes of eating certain foods. The rash resolved within 30 minutes. The patient was diagnosed with auriculotemporal syndrome or Frey syndrome, which is characterized by sweating or flushing in the preauricular area when the patient consumes certain foods, especially those that are acidic, sour, or spicy. Because most patients outgrow the syndrome, no treatment is needed.

The primate vertebral column has been extensively studied, with a particular focus on hominoid primates and the last common ancestor of humans and chimpanzees. The number of vertebrae in hominoids-up to and including the last common ancestor of humans and chimpanzees-is subject to considerable debate. However, few formal ancestral state reconstructions exist, and none include a broad sample of primates or account for the correlated evolution of the vertebral column. Here, we conduct an ancestral state reconstruction using a model of evolution that accounts for both homeotic (changes of one type of vertebra to another) and meristic (addition or loss of a vertebra) changes. Our results suggest that ancestral primates were characterized by 29 precaudal vertebrae, with the most common formula being seven cervical, 13 thoracic, six lumbar, and three sacral vertebrae. Extant hominoids evolved tail loss and a reduced lumbar column via sacralization (homeotic transition at the last lumbar vertebra). Our results also indicate that the ancestral hylobatid had seven cervical, 13 thoracic, five lumbar, and four sacral vertebrae, and the ancestral hominid had seven cervical, 13 thoracic, four lumbar, and five sacral vertebrae. The last common ancestor of humans and chimpanzees likely either retained this ancestral hominid formula or was characterized by an additional sacral vertebra, possibly acquired through a homeotic shift at the sacrococcygeal border. Our results support the 'short-back' model of hominin vertebral evolution, which postulates that hominins evolved from an ancestor with an African ape-like numerical composition of the vertebral column.

Functional abdominal pain disorders (FAPDs) are common in the pediatric population and are associated with a significant reduction in quality of life. Bidirectional communication of the brain-gut axis plays an important role in pain generation and perception in FAPDs. There is a paucity of data on the best approach to treat this group of disorders, with no Food and Drug Administration (FDA)-approved drugs and scarce research to substantiate the use of most medications. Use of hypnosis in pediatric FAPDs is supported by evidence and has long-term benefits of up to at least 5 years beyond completion of treatment, highlighting the importance of incorporating this therapy into the care of these patients. The mechanisms by which clinical hypnosis is beneficial in the treatment of FAPDs is not completely understood, but there is growing evidence that it impacts functioning of the brain-gut axis, potentially through influence on central pain processing, visceral sensitivity, and motility. The lack of side effects or potential for significant harm and low cost makes it an attractive option compared to pharmacologic therapies. This review addresses current barriers to clinical hypnosis including misconceptions among patients and families, lack of trained clinicians, and questions around insurance reimbursement. The recent use of telemedicine and delivery of hypnosis via audio-visual modalities allow more patients to benefit from this treatment. As the evidence base for hypnosis grows, acceptance and training will likely increase as well. Further research is needed to understand how hypnosis works and to develop tools that predict who is most likely to respond to hypnosis. Studies on cost-effectiveness in comparing hypnosis to other therapies for FAPDs will increase evidence for appropriate healthcare utilization. Because hypnosis has applications beyond pain and is child-friendly with minimal to no risk, hypnosis could be an important therapeutic tool in the wider pediatric gastrointestinal population.

BACKGROUND: Solitary use of substances is a risk factor for substance use-related mortality. Novel e-health harm reduction interventions such as virtual overdose monitoring services (VOMS) have emerged in North America to improve access to emergency overdose support for people who use substances (PWUS). To date, little research has been published, and the perspectives of PWUS are needed to inform evaluation and policy efforts. OBJECTIVE: To explore the beliefs, values and perceptions of PWUS around using and accessing VOMS in Canada. METHODS: A qualitative study following grounded theory methodology was conducted. Using existing peer networks, purposive and snowball sampling was conducted to recruit PWUS (≥ 18 years) with previous experience with VOMS. Thematic analysis was used to analyze twenty-three interviews. Several methods were employed to enhance rigor, such as independent data coding and triangulation. RESULTS: Twenty-three one-on-one telephone interviews of PWUS with previous experience with VOMS were completed and analyzed. The following themes emerged: (1) feelings of optimism around VOMS to save lives; (2) privacy/confidentiality was highly valued due to stigma and fear of arrest; (3) concerns with reliable cell phones negatively impacting VOMS uptake; (4) concerns around emergency response times, specifically in rural/remote communities; (5) desire for trusting relationships with VOMS operators; (6) importance of mental health supports and referrals to psychosocial services; and (7) possible limited uptake due to low public awareness of VOMS. CONCLUSION: This qualitative study provided novel insights about the VOMS from the perspectives of PWUS. PWUS generally felt optimistic about the potential of VOMS as a suitable harm reduction intervention, but several potential barriers around accessing VOMS were identified that may limit uptake. Future research is warranted.

BACKGROUND: MRCS examiners are the face of the Royal College of Surgeons for early-career surgeons and should therefore represent the workforce they are examining as not to marginalise or negatively impact on the assessment experience of candidates from minoritised groups. This study aimed to explore the diversity of MRCS examiners and whether they represent the demographics of the MRCS candidates. METHODS: A retrospective observational study including all active examiners and examination candidates who attempted MRCS Part A or Part B between January 2020 and July 2021. Self-declared demographic data collected by the Intercollegiate Committee for Basic Surgical Examinations (ICBSE) included gender, sexual orientation, disability status and ethnicity. Following data anonymisation, total group response frequencies were made available to the research team for statistical analysis. RESULTS: Chi-squared analyses showed statistically significant differences in the representation of gender, disability and ethnicity between candidates and examiners (all p < 0.001). Men (83.9% (n = 1121) vs 70.9% (n = 6017) respectively), individuals without disability (98.7% (n = 917) vs 96.1% (n = 6847)) and individuals of White ethnicity (36.6% (n = 346) vs 20.4% (n = 1223)) were significantly overrepresented in the examiners compared to the examination candidates. There was no statistically significant difference in sexual orientation between examiners and candidates (p = 0.712). CONCLUSIONS: Broadly speaking, the socio-demographic profile of MRCS examiners reflects that seen in senior and leadership positions in surgery in the UK - that is, predominantly male and White - but not that seen in early-career surgeons. Positive action is now required in examiner recruitment by the Royal Colleges to ensure that the cohort of MRCS examiners reflects the modern surgical workforce.

Successful completion of the Intercollegiate Membership of the Royal Colleges of Surgeons (MRCS) examination is mandatory for surgical trainees entering higher specialist training in the United Kingdom. Despite its international reputation, and the value placed on the examination in surgical training, there has been little evidence of its predictive validity until recently. In this review, we present a summary of findings of four recent Intercollegiate studies assessing the predictive validity of the MRCS Part A (written) examination. Data from all four studies showed statistically significant positive correlations between the MRCS Part A and other written examinations taken by surgical trainees over the course of their education. The studies summarised in this review provide compelling evidence for the predictive validity of this gatekeeping examination. This review will be of interest to trainees, training institutions and the Royal Colleges given the value placed on the examination by surgical training programmes.

The Intercollegiate Membership of the Royal Colleges of Surgeons (MRCS) is a high-stakes postgraduate examination taken by thousands of surgical trainees worldwide every year. The MRCS is a challenging assessment, highly regarded by surgical training programmes and valued as a gatekeeper to the surgical profession. The examination is taken at considerable personal, social and financial cost to surgical trainees, and failure has significant implications for career progression. Given the value placed on MRCS, it must be a reliable and valid assessment of the knowledge and skills of early-career surgeons. Our first article 'Establishing the Predictive Validity of the Intercollegiate Membership of the Royal Colleges of Surgeons Written Examination: MRCS Part A' discussed the principles of assessment reliability and validity and outlined the mounting evidence supporting the predictive validity of the MRCS Part A (the multiple-choice questionnaire component of the examination). This, the second article in the series discusses six recently published studies investigating the predictive validity of the MRCS Part B (the clinical component of the examination). All national longitudinal cohort studies reviewed have demonstrated significant correlations between MRCS Part B and other assessments taken during the UK surgical training pathway, supporting the predictive validity of MRCS Part B. This review will be of interest to trainees, trainers and Royal Colleges given the value placed on the examination by surgical training programmes.

The observational retrospective cohort Study on HEalthcare Resource utiLization (HCRU) related to exacerbatiOns in patients with COPD (SHERLOCK; D5980R00014) evaluated exacerbation-related HCRU and costs using the U.K. National Health Service Greater Glasgow and Clyde Health Board data. Patients (≥40 years) with COPD were stratified by exacerbations one year before the index date: Group A (none), B (1 moderate), C (1 severe) and D (≥2 moderate and/or severe). All-cause and COPD-related HCRU and costs were assessed over 36 months. Adjusted rate ratios (RRs) or relative costs versus Group A were estimated using generalized linear models with appropriate distributions and link functions. The study included 22 462 patients (Group A, n = 7788; B, n = 5151; C, n = 250 and D, n = 9273). At 12 months, RRs (95% CI) versus Group A for all-cause and COPD-related HCRU, respectively, were highest in Groups C (1.28 [1.18, 1.39] and 1.18 [1.09, 1.29]) and D (1.26 [1.23, 1.28] and 1.29 [1.26, 1.31]). General practitioner and outpatient visits, and general ward stays/days accounted for the greatest COPD-related HCRU. All-cause and COPD-related relative costs (95% CI) versus Group A at 12 months, respectively, were 1.03 (0.94, 1.12) and 1.06 (0.99, 1.13) in Group B; 1.47 (1.07, 2.01) and 1.54 (1.20, 1.97) in Group C; 1.47 (1.36, 1.58) and 1.63 (1.54, 1.73) in Group D. Increased HCRU and costs in patients with exacerbation histories persisted at 36 months, demonstrating the sustained impact of exacerbations. The study suggests the importance of management and prevention of exacerbations through intervention optimization and budgeting by payers for exacerbation-related costs.

INTRODUCTION: The History, Electrocardiogram (ECG), Age, Risk Factors and Troponin (HEART) score is commonly used to risk stratify patients with possible myocardial infarction as low risk or high risk in the Emergency Department (ED). Whether the HEART score can be used by paramedics to guide care were high-sensitivity cardiac troponin testing available in a prehospital setting is uncertain. METHODS: In a prespecified secondary analysis of a prospective cohort study where paramedics enrolled patients with suspected myocardial infarction, a paramedic Heart, ECG, Age, Risk Factors (HEAR) score was recorded contemporaneously, and a prehospital blood sample was obtained for subsequent cardiac troponin testing. HEART and modified HEART scores were derived using laboratory contemporary and high-sensitivity cardiac troponin I assays. HEART and modified HEART scores of ≤3 and ≥7 were applied to define low-risk and high-risk patients, and performance was evaluated for an outcome of major adverse cardiac events (MACEs) at 30 days. RESULTS: Between November 2014 and April 2018, 1054 patients were recruited, of whom 960 (mean 64 (SD 15) years, 42% women) were eligible for analysis and 255 (26%) experienced a MACE at 30 days. A HEART score of ≤3 identified 279 (29%) as low risk with a negative predictive value of 93.5% (95% CI 90.0% to 95.9%) for the contemporary assay and 91.4% (95% CI 87.5% to 94.2%) for the high-sensitivity assay. A modified HEART score of ≤3 using the limit of detection of the high-sensitivity assay identified 194 (20%) patients as low risk with a negative predictive value of 95.9% (95% CI 92.1% to 97.9%). A HEART score of ≥7 using either assay gave a lower positive predictive value than using the upper reference limit of either cardiac troponin assay alone. CONCLUSIONS: A HEART score derived by paramedics in the prehospital setting, even when modified to harness the precision of a high-sensitivity assay, does not allow safe rule-out of myocardial infarction or enhanced rule-in compared with cardiac troponin testing alone.

BACKGROUND: The COVID-19 pandemic has posed a global health threat and has had a profoundly negative impact on the work and lives of healthcare workers. However, few people know how their experiences have evolved over time. AIMS: To describe healthcare workers' experiences during clinical responses to COVID-19 and how they changed over time. DESIGN: A longitudinal qualitative study. METHODS: We undertook a series of four semi-structured qualitative interviews of 14 healthcare workers called as 1st responders to the COVID-19 pandemic. Participants were recruited through purposive snowball sampling. Interviews were undertaken between May 2020 and May 2022 and trajectory approach was used to reveal individual experiences over time. This paper follows the COREQ (Consolidated criteria for Reporting Qualitative Research) guidance. RESULTS: Data analysis yielded the following four themes: (1) Changes in emotions; (2) Changes in organization and management of care; (3) Changes in knowledge and capabilities; and (4) Changes in outlook on life and career. CONCLUSION: Healthcare workers have become stronger in the pandemic and have demonstrated a high degree of professional loyalty and responsibility. However, there is a need to focus on the issue of jealousy and create a harmonious and safe work environment to reduce harm to healthcare workers. Additionally, human resource management strategies must support well-being of healthcare workers and maximize the efficiency of human resource utilization to enable them to respond to current and future needs and emergencies.
