Background The treatment of osteoarthritis with knee replacement aims to reduce pain and disability. However, some people experience chronic pain. Objectives To improve outcomes for people with chronic pain after knee replacement by identifying post-surgical predictors and effective interventions, characterising patient pathways and resource use, developing and evaluating a new care pathway, and exploring non-use of services. Design The programme comprised systematic reviews, national database analyses, a cohort study, intervention development, a randomised controlled trial, health economic analyses, qualitative studies and stakeholder engagement. Extensive and meaningful patient and public involvement underpinned all studies. Setting NHS, secondary care, primary care. Participants People with, or at risk of, chronic pain after knee replacement and health-care professionals involved in the care of people with pain. Interventions A care pathway for the management of people with pain at 3 months after knee replacement. Main outcome measures Patient-reported outcomes and cost-effectiveness over 12 months. Data sources Literature databases, the National Joint Registry, Hospital Episode Statistics, patient-reported outcomes, the Clinical Practice Research Datalink, the Clinical Outcomes in Arthroplasty Study, the Support and Treatment After joint Replacement randomised trial, interviews with 90 patients and 14 health-care professionals, and stakeholder events. Review methods Systematic reviews of cohort studies or randomised trials, using meta-analysis or narrative synthesis. Results In the Clinical Outcomes in Arthroplasty Study cohort, 14% of people experienced chronic pain 1 year after knee replacement. By 5 years, 65% reported no pain, 31% fluctuated and 4% remained in chronic pain. People with chronic pain had a worse quality of life, higher primary care costs, and more frequent analgesia prescriptions, particularly for opioids, than those not in chronic pain. People with chronic pain after knee replacement who made little or no use of services often felt nothing more could be done, or that further treatments may have no benefit or cause harm. People described a feeling of disconnection from their replaced knee. Analysis of UK databases identified risk factors for chronic pain after knee replacement. Pre-operative predictors were mild knee pain, smoking, deprivation, body mass index between 35 and 40 kg/m2 and knee arthroscopy. Peri- and post-operative predictors were mechanical complications, infection, readmission, revision, extended hospital stay, manipulation under anaesthetic and use of opioids or antidepressants. In systematic reviews, pre-operative exercise and education showed no benefit in relation to chronic pain. Peri-operative interventions that merit further research were identified. Common peri-operative treatments were not associated with chronic pain. There was no strong evidence favouring specific post-operative physiotherapy content. We evaluated the Support and Treatment After joint Replacement care pathway in a multicentre randomised controlled trial. We randomised 363 people with pain at 3 months after knee replacement from eight NHS Trusts in England and Wales. At 12 months’ follow-up, the intervention group had lower mean pain severity (adjusted difference –0.65, 95% confidence interval –1.17 to -0.13; p = 0.014) and pain interference (adjusted difference –0.68, 95% confidence interval –1.29 to -0.08; p = 0.026), as measured on the Brief Pain Inventory subscales (scale 0–10). People receiving the Support and Treatment After joint Replacement pathway had lower NHS and Personal Social Services costs (–£724, 95% confidence interval –£150 to £51) and higher quality-adjusted life-years (0.03, 95% confidence interval –0.008 to 0.06) than those with usual care. The Support and Treatment After joint Replacement pathway was cost-effective with an incremental net monetary benefit at the £20,000 per quality-adjusted life-year threshold of £1256 (95% confidence interval £164 to £2348), indicating a 98.79% probability that the intervention is the cost-effective option. Participants found the Support and Treatment After joint Replacement pathway acceptable, with opportunities to receive information and discuss concerns while ensuring further treatment and support. In systematic reviews considering treatments for chronic pain after surgery we identified some unifactorial interventions that merit further research after knee replacement. Health-care professionals delivering and implementing the Support and Treatment After joint Replacement pathway valued its focus on neuropathic pain and psychosocial issues, enhanced patient care, formalised referrals, and improved pain management. Stakeholders supported pathway implementation. Limitations Database analyses were limited to factors recorded in data sets. Pain was only measured 6 months after surgery. However, analyses including large numbers of centres and patients should be generalisable across the NHS. In many studies found in systematic reviews, long-term pain was not a key outcome. Conclusions The Support and Treatment After joint Replacement pathway is a clinically effective and cost-effective, acceptable intervention for the management of chronic pain after knee replacement. Unifactorial interventions merit further study before inclusion in patient care. People with pain should be empowered to seek health care, with the support of health-care professionals. Future work Future work should include research relating to the implementation of the Support and Treatment After joint Replacement pathway into the NHS, an assessment of its long-term clinical effectiveness and cost-effectiveness and wider application, and an evaluation of new interventions for incorporation in the pathway. It will also be important to design and conduct research to improve communication between patients and health-care professionals before surgery; explore whether or not education and support can enable earlier recognition of chronic pain; consider research that may identify how to support people’s feelings of disconnectedness from their new knee; and design and evaluate a pre-surgical intervention based on risk factors. Study registration All systematic reviews were registered on PROSPERO (CRD42015015957, CRD42016041374 and CRD42017041382).

Although highly successful for many people, some people report long-term pain. Our research looked at why some people are more likely to have long-term pain, its personal and economic consequences, and how to prevent and treat it. We reviewed previous research; analysed UK health-care databases; interviewed and met with patients, surgeons and health-care professionals; and developed and evaluated a new care pathway for patients with pain after knee replacement. We found that about one in seven people experience significant pain 6 months after knee replacement. For many, pain fluctuates over time. Some people with long-term pain feel that nothing more can be done to help and that further treatments may even cause harm. Changes to aspects of patient health and care merit further research as they may prevent the development of long-term pain. The Support and Treatment After joint Replacement pathway comprises a detailed assessment by a trained health-care professional; referral to appropriate services, such as an orthopaedic surgeon, physiotherapist, general practitioner for treatment of depression or anxiety, or pain specialist; and telephone follow-up. A total of 363 people with pain at 3 months after their knee replacement were randomly allocated to receive either the Support and Treatment After joint Replacement pathway or their hospital’s usual care. Participants were followed for 1 year to assess their long-term pain. We also looked at health-care costs and the acceptability of the Support and Treatment After joint Replacement pathway to patients and health-care professionals. This research was supported by a dedicated patient advisory group. For people with pain after knee replacement, the Support and Treatment After joint Replacement pathway leads to reduced long-term pain severity and reduced interference with everyday life, and is acceptable to patients and health-care professionals. NHS, personal social services and patient costs were lower in the group receiving the Support and Treatment After joint Replacement pathway. Scientific summary Background Chronic pain after total knee replacement places considerable burden on individuals, society and the NHS. With nearly 100,000 patients receiving knee replacements in the NHS annually, around 20,000 patients will have chronic post-surgical pain. Pre-operative prediction of who will have chronic pain after knee replacement is of limited value, referral for assessment and care is inconsistent and varies widely, and people do not necessarily receive or seek care. This programme aimed to address these issues and provide evidence on improvements to patient care and service delivery. Objectives The programme aimed to improve outcomes for patients with chronic pain ≥ 3 months after total knee replacement. Specific programme objectives were as follows: 1.synthesise evidence on the effectiveness of interventions for preventing chronic pain after knee replacement and the treatment of chronic pain after diverse surgeries, and identify post-surgical predictors of chronic pain after knee replacement 2.characterise the long-term trajectory of chronic pain, including pain characteristics and resource use up to 5 years after total knee replacement 3.finalise an assessment process and a care pathway for patients with chronic pain after total knee replacement 4.evaluate the clinical effectiveness and cost-effectiveness of a new care pathway for patients with chronic pain after total knee replacement 5.identify reasons for non-use of services 6.make evidence-based suggestions about the best-practice care for patients with chronic pain after total knee replacement and evaluate the implementation of these. Methods To meet the objectives, we conducted six work packages. Work package 1: systematic reviews and analysis of national databases Systematic reviews of the following were carried out: post-surgical predictors of chronic pain after total knee replacement; the effectiveness of pre-, peri- and post-operative interventions for chronic pain after total knee replacement; and the effectiveness of interventions for chronic pain after diverse surgeries. In addition, we undertook an analysis of data from the National Joint Registry (NJR) linked to Hospital Episode Statistics (HES) and Patient Reported Outcome Measures (PROMs) databases to identify post-operative predictors of chronic pain. Work package 2: long-term follow-up and analysis of databases Using the annual follow-up of the Clinical Outcomes in Arthroplasty Study (COASt) cohort of patients with total knee replacement, we were able to collect pain and resource use data for 5 years after surgery. We also analysed the Clinical Practice Research Datalink (CPRD), linked to the Hospital Episode Statistics (HES) and Patient Reported Outcome Measures (PROMs) database, to characterise the natural history of chronic pain after total knee replacement, including resource use. Work package 3: finalisation of an assessment protocol and care pathway Consensus questionnaires completed by and meetings with health-care professionals were used to refine our previously developed intervention. We also tested intervention delivery and acceptability with 10 patients and evaluated the views of 10 health-care professional stakeholders on future implementation using a questionnaire based on the Normalisation Measure Development (NoMAD) instrument. Work package 4: randomised controlled trial The multicentre Support and Treatment After joint Replacement (STAR) randomised controlled trial was carried out with 363 participants to evaluate the clinical effectiveness and cost-effectiveness of a new care pathway for patients with chronic pain after total knee replacement. The primary follow-up time point was 12 months post randomisation and the coprimary outcomes were the Brief Pain Inventory (BPI) severity and interference scales (scored 0–10), with the minimal clinically important difference pre-specified as 1 point on either scale. Two embedded qualitative studies with 56 patients explored trial processes and acceptability of the intervention. Work package 5: qualitative study We undertook a qualitative interview study with 34 people with chronic pain after total knee replacement who made little or no use of formal health-care services and explored reasons for non-use of services. Work package 6: implementation and dissemination Interviews, based on the NoMAD instrument, were carried out with 14 health-care professionals who implemented the intervention within the trial. An online meeting, short animated film and survey were all used to communicate findings to key stakeholders and engage health-care professionals in maximising the embedding of the intervention in practice. A range of dissemination activities to engage health-care professionals, researchers, policy-makers, patients and the public were undertaken. Patient and public involvement Patient and public involvement was integral to the programme’s design and remained at its core during the programme. We worked with an existing patient forum and developed a complementary group focusing exclusively on chronic pain after total knee replacement. Contributions of this group included the design of study materials and processes, research management and dissemination strategies. Results Work package 1: systematic reviews Our systematic review of post-operative risk factors for chronic pain after total knee replacement included 14 studies published up to October 2016, with data from 1168 people. Studies focused on acute pain, function and psychological factors. Risk factor measures and outcomes were heterogeneous. In a narrative synthesis we were unable to draw firm conclusions on potential interventions. The need for further prospective studies in representative populations was clear. Research published up to December 2018 into pre-operative interventions mainly focused on exercise and education. In the eight trials, with a total of 960 people randomised, there was no association with these interventions and long-term pain outcomes. In the peri-operative setting, we identified 44 trials published up to February 2018, with a range of 10 to 280 people randomised. Unifactorial interventions including some forms of analgesia, early rehabilitation, electrical muscle stimulation and anabolic steroids were associated with improved long-term pain outcomes. However, studies were small and merit further evaluation. There was reassurance that some common peri-operative treatments are not associated with chronic pain. Post-operative interventions evaluated in 17 trials published up to November 2016, with a total of 2485 people randomised, mainly focused on physiotherapy. There was no strong evidence favouring one format of therapy over another. There has been little research into treatments for chronic pain after total knee replacement. Considering interventions for general chronic post-surgical pain, we identified 66 randomised trials with a total of 3149 participants in our systematic review with searches up to March 2016. A more focused updated search including treatments for chronic pain after arthroplasty of the large joints was conducted in October 2020. Many unifactorial interventions have been evaluated, and specific nerve-focused treatments deserve further research. Work packages 1 and 2: analysis of national databases We undertook two analyses of linked databases to identify pre-, peri- and post-operative risk factors for chronic pain outcome. In the first analysis with NJR and HES data, the pre- and 6-month-post-operative Oxford Knee Scores (OKS) was available for 258,386 patients, 43,702 (16.9%) of whom were identified as having chronic pain at 6 months post surgery. Post-surgical predictors of chronic pain were mechanical complication of prosthesis, surgical site infection, readmission, reoperation, revision and an extended hospital stay. However, these post-surgical predictors explained only a limited amount of variability in chronic pain outcome. In the second analysis, we analysed primary care data from CPRD and secondary care data from the HES–PROMs database and included 4570 patients. At 6 months after surgery, 10.4% of patients were classified as non-responders to surgery regarding their knee pain. Expressing the effects as absolute risk differences allowed us to quantify the relative importance of individual risk factors in terms of the absolute proportions of patients achieving poor pain outcomes. Pre-operative risk factors were having only mild knee pain symptoms, currently smoking, living in the most deprived areas, having a body mass index between 35 and 40 kg/m2 and having had previous knee arthroscopy surgery. Post-operative risk factors were revision surgery and manipulation under anaesthetic within 3 months after the operation, and use of opioids and antidepressants within 3 months after surgery. Work package 2: long-term follow-up of COASt cohort and analysis of national databases We characterised the long-term trajectory of chronic pain, including pain characteristics and resource use, through the 5-year follow-up of the COASt cohort of 1581 patients with total knee replacement, and analysis of the linked CPRD and HES databases. We applied cluster analysis to data on 128,145 patients with primary total knee replacement included in the English PROMs programme to derive a cut-off point on the pain subscale of the OKS. A high-pain group was identified, defined as those with a score of ≤ 14 points on the OKS pain subscale 6 months after total knee replacement. About one in eight people experienced chronic pain 1 year after total knee replacement. Of these patients with chronic pain after surgery, after imputing significant missing data assumed to be missing at random, 65% experienced no-chronic-pain by year 5, 31% fluctuated and 4% remained in chronic pain. People with chronic pain in year 1 had worse quality of life to start with; this improved, but less rapidly than for those not in chronic pain. People with chronic pain reported slightly higher primary care consultation costs than those not in chronic pain but their prescriptions for analgesia were much more frequent, more costly to the health-care system and continued to grow even after surgery, especially prescriptions for opioids. Work package 3: finalisation of an assessment protocol and care pathway We refined and finalised the novel STAR care pathway and associated training materials. The STAR care pathway involves a clinic appointment for patients who have troublesome pain at 3 months after surgery. A specially trained extended scope practitioner (ESP) conducts a clinic assessment with the patient, comprising history, examination, radiography and questionnaire completion. Based on this assessment, which focuses on understanding the reasons for and impact of the pain, the patient is referred to the appropriate existing services for treatment, such as a surgeon, general practitioner (GP) or specialist, or receives ongoing monitoring. The ESP follows up with patients by telephone for up to 12 months. Work package 4: randomised controlled trial In a multicentre pragmatic, open randomised controlled trial, we evaluated the STAR care pathway. We screened 5036 people, randomised 363 patients with pain at 3 months after knee replacement from eight NHS Trusts in England and Wales and collected 12-month outcomes from 313 (85%) randomised participants. The sample had a mean age of 67 years, was 60% female and 94% white. Our analysis of clinical effectiveness indicated that at 12 months the intervention arm had lower mean pain severity and lower mean pain interference than the usual care arm. For pain interference at 12 months, the adjusted difference in means was –0.68 points on the Brief Pain Inventory pain interference scale [95% CI –1.29, –0.08; p = 0.026]. For pain severity at 12 months, the adjusted difference in means was –0.65 points on the Brief Pain Inventory pain severity scale [95% CI –1.17, –0.13; p = 0.014]. Our analysis of cost-effectiveness indicated that people receiving the STAR pathway from an NHS and personal social services perspective had lower costs (–£724, 95% CI -£1500 to £51) and more quality-adjusted life-years (QALYs) (0.03, 95% CI –0.008 to 0.06) than those receiving usual care. The STAR pathway was the cost-effective option: the incremental net monetary benefit at the £20,000-per-QALY threshold was £1256 (95% CI £164 to £2348). This was also the case from a patient perspective. Embedded qualitative research found that patients thought that the STAR pathway was acceptable, and patients described how it provided an opportunity for them to discuss their concerns and to receive more information about their condition while ensuring they received further treatment and ongoing support. Work package 5: qualitative study In semistructured interviews with 34 people, we found that people with chronic pain after total knee replacement who made little or no use of services did so because they became stuck in a cycle of appraisal of the validity of their need for help and concern that treatment may not be of benefit. Some were concerned that further treatment may even worsen their pain or cause further harm. When describing chronic post-surgical pain, some participants described sensations of discomfort including heaviness, numbness, pressure and tightness associated with the prosthesis, and some also reported a lack of felt connection with their knee as their movement was no longer natural and required deliberate attention, and that they had a lack of confidence in it. Work package 6: implementation and dissemination We found that health-care professionals involved in the delivery and implementation of the STAR care pathway valued its focus on the identification of neuropathic pain and psychosocial issues, enhanced patient care, formalisation and validation of referral practices and an increased knowledge of pain management. Stakeholders supported formal implementation of the STAR pathway. Whether or not this would be supported by hospital management was felt to be dependent on whether or not it was shown to be cost-effective. Conclusions: implications for health care After knee replacement, screening for pain with the OKS pain subscale beginning at 2 months after surgery can facilitate the delivery of targeted care from 3 months. Our findings indicate that the STAR care pathway can provide improved care and outcomes for people who have pain after knee replacement. To our knowledge, the STAR care pathway is the first multifactorial intervention for the treatment of post-surgical pain to have been evaluated in a randomised controlled trial. In database analyses and systematic reviews, we identified risk factors for and univariable interventions to prevent or treat chronic pain. After further research these may provide additional components to the care pathway. Our work also indicates that people with pain could be empowered to seek health care and that health-care professionals can be encouraged provide support. This could include information for people living with chronic pain to inform them that health care may provide benefit and that seeking care is not futile. Informing patients of the likely outcomes after surgery may be a key part of pre- and post-surgical care. Recommendations for research We recommend that further research addresses the following points, numbered in descending order of priority: 1.How to implement the STAR care pathway into the NHS. 2.How to improve communication between patients and professionals before surgery. 3.Whether or not patient education and supportive care can enable earlier recognition of chronic pain. 4.The STAR care pathway showed benefit to patients for both pain and interference at 6 and 12 months. Further follow-up would describe the longer-term outcomes of this intervention and the health-care resources utilised by participants. 5.How to reshape the STAR pathway for other surgeries. 6.The STAR programme focused on care after surgery. Future research could make use of the recently developing evidence base about the time before surgery as an opportunity for intervention. Specifically, we now have a greater understanding of risk factors for poor outcome and using this understanding to design and evaluate pre-surgical intervention may prove of long-term benefit to patients and health-care systems. 7.How to better manage patient’s feelings of disconnectedness from the new knee and sensations of otherness to improve incorporation of the prosthesis. 8.Promising interventions, identified in systematic reviews and suggested by our risk factor studies, should be evaluated in appropriately powered high-quality randomised controlled trials. 9.New interventions with evidence of effectiveness in the treatment of chronic pain after knee replacement should be considered as new components of multifaceted personalised care as delivered in the STAR intervention.

This study aims to understand how students manage higher technical education and contribute to research on institutional culture, STEM education, and students' educational strategies by identifying patterns of how students navigate within one university's engineering education. To achieve this, we define and use the concept of technical science capital and habitus reconstruction. We collected data through a survey sent to engineering students who have followed an engineering program's intended linear progression and those who have taken a 'detour' within the same cohort at one specific Swedish university. The survey had a high number of qualitative questions, including free text answers that captured students' narratives. The results indicate that having a large amount of technical science capital alone is not enough for students to be successful in their studies. The university culture has its own structure, which can be intolerant. Within this culture, specific social skills and experiences are desirable, which provides students from a particular background with a greater opportunity for success. Despite possessing high technical science capital, students from other social groups or cultures face challenges. We discuss various measures that could make higher technical education more engaging. This study is limited to one Swedish university, and future studies could include a broader sample that represents several universities.

The use of professional internships has long been a defining feature of journalism and mass communication programs, but the practice is also increasingly controversial for the financial burdens it places on marginalized students. This study examined accreditation reports for 120 institutions to gain a better understanding of current practices. Findings showed that almost all universities offer internships for credit, and about two fifths of the programs require them. Most programs use internship data to assess student learning outcomes.

There is an increased focus on fostering integrity in research by through creating an open culture where research integrity dilemmas can be discussed. We describe a pilot intervention study that used Moral Case Deliberation (MCD), a method that originated in clinical ethics support, to discuss research integrity dilemmas with researchers. Our research question was: can moral case deliberation in research groups help to navigate research integrity dilemmas? We performed 10 MCDs with 19 researchers who worked in three different research groups from three different disciplinary fields at a university in the Netherlands. We analyzed the dilemmas and values discussed, sent out a survey questionnaire to assess self-perceived moral competencies, and conducted in-depth interviews. We found research integrity dilemmas pertained to authorship disputes, supervision of junior co-workers, and questionable handling of data. Participants perceived the majority of moral competencies to a higher degree during the MCD when compared to perceiving them in daily practice afterward. Interviewees told us that they felt most comfortable discussing dilemmas among peers with whom they were not closely affiliated. We conclude that MCD sessions could be relevant in navigating research integrity dilemmas, but that revisions to ensure commitment and safety are required.

A learning crisis across Arabic-speaking countries is leading to human capital deficits, undermining efforts to reduce poverty and putting achievement of the Sustainable Development Goals at risk. The World Bank has introduced the concept of learning poverty to highlight this crisis -- measured as the percentage of 10- year-old children who are unable to read and understand a simple text. In the Middle East and North Africa (MENA) region, this affects around 6 in 10 children, and likely more, because of the COVID-19-related school disruptions. The World Bank has proposed a path to reduce learning poverty through advancing Arabic language teaching and learning. The proposed path comprises a set of purposeful actions that governments and stakeholders can take to reorient education systems so that they can best achieve essential core Arabic language skills and learning for all. This includes, for example, setting literacy goals, aligning instructional resources to follow a systematic phonetic approach with a focus on reading comprehension in a literature-rich environment, ensuring high-quality instruction, and identifying and intervening early with struggling readers. As the largest external financier of education in the developing world, the World Bank has a significant role to play in helping countries to recognize these key challenges and to mobilize resources to address them effectively and efficiently. This paper outlines the World Bank's approach and explores how it is taking shape in the World Bank's support to countries' education programs across the MENA region.

Purpose: Halfway into the United Nations (UN) sustainable development goals (SDGs) timeline, we deemed fruitful an injunction into current teacher education (TE) practices at higher educational institutes (HEIs). The scoping literature review used all known English nomenclature interrelating to environment, sustainability, development, and education as regards TE. We explicated and modelled the data through timelines favourable to UN initiatives within a spatiotemporal metric. Thematic research topics and research methodologies strictly pertaining to TE were rigorously researched and delineated. Our study aims to elucidate a grander picture of the trends-as-patterns of environmental and sustainability education in teacher education (ESE-TE) research in HEI and potential contributions to come. Design/methodology/approach: The spatiotemporal study adopts a scoping review as an investigative tool to probe current research trends on ESE-TE in the academic literature with respect to thematic research topics and research methodologies midway through the SDGs. Findings: A total of 2,142 research papers spanning five decades, 152 journals and 96 countries were screened equally by two researchers. Of the 788 papers deemed eligible (i.e. English-language, peer-reviewed, pre-service/in-service TE that explicitly mentioned ESE-TE research), data from 638 studies have been included in the authors' study. Originality/value: Comprehensive trends in the international literature of all known environmental and sustainable education nomenclature specific to international ESE-TE research throughout the time period (1974-2021) were identified. Value is accrued by illuminating international trends in research topics and methodologies, exposing gaps in the history of the subfield, and predicting future trends for Agenda 2030 (e.g. SDG 4 -- education) to mature the field.

Abstract Background Branch pulmonary artery (PA) stenosis is one of the most common indications for percutaneous interventions in patients with transposition of the great arteries (TGA), tetralogy of Fallot (ToF), and truncus arteriosus (TA). However, the effects of percutaneous branch PA interventions on exercise capacity remains largely unknown. In addition, there is no consensus about the optimal timing of the intervention for asymptomatic patients according to international guidelines. This trial aims to identify the effects of percutaneous interventions for branch PA stenosis on exercise capacity in patients with TGA, ToF, and TA. In addition, it aims to assess the effects on RV function and to define early markers for RV adaptation and RV dysfunction to improve timing of these interventions. Methods This is a randomized multicenter interventional trial. TGA, ToF, and TA patients ≥ 8 years with a class IIa indication for percutaneous branch PA intervention according to international guidelines are eligible to participate. Patients will be randomized into the intervention group or the control group (conservative management for 6 months). All patients will undergo transthoracic echocardiography, cardiac magnetic resonance (CMR) imaging, and cardiopulmonary exercise testing at baseline, 6 months, and 2–4 years follow-up. Quality of life (QoL) questionnaires will be obtained at baseline, 2 weeks post intervention or a similar range for the control group, and 6 months follow-up. The primary outcome is exercise capacity expressed as maximum oxygen uptake (peak VO2 as percentage of predicted). A total of 56 patients (intervention group n = 28, control group n = 28) is required to demonstrate a 14% increase in maximum oxygen uptake (peak VO2 as percentage of predicted) in the interventional group compared to the control group (power 80%, overall type 1 error controlled at 5%). Secondary outcomes include various parameters for RV systolic function, RV functionality, RV remodeling, procedural success, complications, lung perfusion, and QoL. Discussion This trial will investigate the effects of percutaneous branch PA interventions on exercise capacity in patients with TGA, ToF, and TA and will identify early markers for RV adaptation and RV dysfunction to improve timing of the interventions. Trial registration ClinicalTrials.gov NCT05809310. Registered on March 15, 2023.

The placebo effect is a fascinating phenomenon that has advanced beyond the medical field into the field of sport and exercise psychology. The goal of the present study was to expand this literature by investigating the effects of expectation manipulation on perceived physical, affective, and cognitive benefits following exercise. To address this aim, 77 young adults (Mage = 29.84, SD = 9.83) were asked to rate the expected cognitive, affective, and physical benefits of a stretching program, and to elaborate on their ratings via an online survey. Participants were randomly allocated to three expectation conditions: expectation-benefit, expectation-no benefit, or no expectation control. All participants were evaluating the same stretching program, but read fictitious testimonies and watched videos that were aimed at manipulating their expectations. Analyses revealed that the expectation-benefit group expected higher cognitive and affective benefits from the stretching program than the expectation-no benefits group (ps < 0.001). No significant differences emerged on the expectation to receive physical benefits among all three groups. The thematic analysis of participants’ rationale for their ratings revealed that beliefs about benefits were modified through the testimonies and videos provided. Participants also relied on their previous knowledge or experience about stretching to inform their predictions about the expected benefits of the stretching program. Results from this study expand the knowledge on expectations manipulation in exercise settings, and provide exercise professionals with strategies to maximize the benefits participants can receive from exercise.

Abstract Background Despite WHO’s recommendation of limited screen time for children

Objective To identify evidence-based interventions that reduce greenhouse gas emissions in health-care systems in low-and middleincome countries and explore potential synergies from these interventions that aid climate change adaptation while mitigating emissions. Methods We systematically searched 11 electronic databases for articles published between 1990 and March 2023. We assessed risk of bias in each article and graded the quality of evidence across interventions in health-care operations, energy and supply chains. Findings After screening 25 570 unique records, we included 22 studies published between 2000 and 2022 from 11 countries across six World Health Organization regions. Identified articles reported on interventions spanning six different sources of emissions, namely energy, waste, heating and cooling, operations and logistics, building design and anaesthetic gases; all of which demonstrated potential for significant greenhouse gas emission reductions, cost savings and positive health impacts. The overall quality of evidence is low because of wide variation in greenhouse gas emissions measuring and reporting. Conclusion There are opportunities to reduce the greenhouse gas emissions from health-care systems in low- and middle- income countries, but gaps in evidence were identified across sources of emissions, such as the supply chain, as well as a lack of consideration of interactions with adaptation goals. As efforts to mitigate greenhouse gas intensify, rigorous monitoring, evaluation and reporting of these efforts are needed. Such actions will contribute to a strong evidence base that can inform policy-makers across contexts. Objectif Identifier les interventions fondees sur des donnees factuelles qui visent a reduire les gaz a effet de serre emanant des systemes de soins de sante dans les pays a revenu faible et intermediaire, mais aussi explorer d'eventuel les synergies liees a ces interventions et susceptibles de contribuer a une meilleure adaptation au changement climatique tout en reduisant les emissions. Methodes Nous avons procede a une analyse systematique de 11 bases de donnees electroniques, a la recherche d'articles publies entre 1990 et mars 2023. Pour chaque article, nous avons determine le risque de biais et evalue la qualite des donnees relatives aux interventions dans les unites de soins de sante, l'energie et les cha nes d'approvisionnement. Resultats Apres avoir examine 25 570 documents uniques, nous avons conserve 22 etudes publiees entre 2000 et 2022, issues de 11 pays appartenant a six regions de l'Organisation mondiale de la Sante. Les articles retenus mentionnaient des interventions couvrant six sources d'emissions differentes, a savoir l'energie, les dechets, le chauffage et la climatisation, les operations et services logistiques, la conception des b timents, ainsi que les gaz anesthesiques; toutes ont revele un potentiel en matiere de reduction des emissions de gaz a effet de serre, de realisation d'economies et d'impact positif sur la sante. Globalement, les donnees sont de pietre qualite en raison des variations des mesures et rapports concernant les emissions de gaz a effet de serre. Conclusion Il existe plusieurs moyens de reduire les emissions de gaz a effet de serre provenant des systemes de soins de sante dans les pays a revenu faible et intermediaire. Cependant, les preuves sur les sources d'emissions manquent, notamment au niveau de la cha ne d'approvisionnement, et les interactions a des fins d'adaptation ne sont que rarement prises en compte. Alors que les efforts visant a reduire ces emissions se multiplient, il est imperatif de les surveiller, de les evaluer et d'etablir des rapports rigoureux. De telles actions contribueront a mieux etayer les donnees afin d'orienter les responsables politiques en fonction du contexte. Objetivo Identificar intervenciones basadas en evidencias que reduzcan las emisiones de gases de efecto invernadero en los sistemas sanitarios de los paises de ingresos bajos y medios y explorar las posibles sinergias de estas intervenciones que ayuden a adaptarse al cambio climatico mientras se mitigan las emisiones. Metodos Se realizaron busquedas sistematicas en 11 bases de datos electronicas de articulos publicados entre 1990 y marzo de 2023. Se evaluo el riesgo de sesgo en cada articulo y se clasifico la calidad de las pruebas en las intervenciones relacionadas con las operaciones sanitarias, la energia y las cadenas de suministro. Resultados Tras examinar 25 570 registros unicos, se incluyeron 22 estudios publicados entre 2000 y 2022 de 11 paises de seis regiones de la Organizacion Mundial de la Salud. Los articulos identificados informaron sobre intervenciones que abarcaban seis fuentes diferentes de emisiones: energia, residuos, calefaccion y refrigeracion, operaciones y logistica, diseno de edificios y gases anestesicos; todos ellos demostraron potencial para reducciones significativas de las emisiones de gases de efecto invernadero, ahorro de costes e impactos positivos en la salud. La calidad general de las evidencias es baja debido a la gran variacion en la medicion y la notificacion de las emisiones de gases de efecto invernadero. Conclusion Existen oportunidades para reducir las emisiones de gases de efecto invernadero de los sistemas de atencion sanitaria en los paises de ingresos bajos y medios, pero se han detectado deficiencias en las evidencias de las diferentes fuentes de emisiones, como la cadena de suministro, asi como una falta de consideracion de las interacciones con los objetivos de adaptacion. A medida que se intensifican los esfuerzos para mitigar los gases de efecto invernadero, es necesario realizar un seguimiento, una evaluacion y una notificacion rigurosos de estos esfuerzos. Estas medidas contribuiran a crear una base de evidencias solida que pueda informar a los responsables de formular las politicas en todos los contextos., Introduction In the absence of actions to rapidly reduce global greenhouse gas emissions, climate change is predicted to be the biggest threat to human health in the 21st century.

The current sociopolitical climate within the United States puts teachers--particularly those in the humanities--at the focal point of opposing forces regarding antiracist pedagogy. National teaching organizations, like NCTE, task humanities [...]

Abstract The International Network on Esophageal Atresia (INoEA) stands as a beacon of collaboration in addressing the complexities of this congenital condition on a global scale. The eleven board members, from various countries (USA, Canada, France, Australia, Italy, Sweden, Germany, and The Netherlands) and backgrounds (pediatric gastroenterology, pediatric surgery, pediatric pulmonology, nursing, and parents) met in a face-to-face symposium in Lille in November 2023, to identify challenges and solutions for improving global collaboration of the network.
