Using a learning theory is key when designing simulation-based learning linked to allied health professional placements to ensure the purposeful selection of educational methods and to understand how it may assist learners in achieving desired learning outcomes. A narrative review was undertaken to identify the learning theories reported in simulation-based learning linked to allied health professional placements and how the learning outcomes aligned with the reported theories. Only eight of the 25 reviewed studies explicitly reported a learning theory, with minimal attempt to link them to the learning experience. Educators are encouraged to develop an understanding of the breadth and depth of learning theories and how they can best align these with the desired learning outcomes to allow the best fit for purpose. As a result, the authors have developed a practical guide to assist educators in designing simulation-based learning to better understand how learning theories could be incorporated and the anticipated outcomes that could be measured.

Abstract Smartphone applications are one of the main delivery modalities in digital health. Many of these mHealth apps use gamification to engage users, improve user experience, and achieve better health outcomes. Yet, it remains unclear whether gamified approaches help to deliver effective, safe, and clinically beneficial products to users. This study examines the compliance of 69 gamified mHealth apps with the EU Medical Device Regulation and assesses the specific risks arising from the gamified nature of these apps. Of the identified apps, 32 (46.4%) were considered non-medical devices; seven (10.1%) were already cleared/approved by the regulatory authorities, and 31 (44.9%) apps were assessed as likely non-compliant or potentially non-compliant with regulatory requirements. These applications and one approved application were assessed as on the market without the required regulatory approvals. According to our analysis, a higher proportion of these apps would be classified as medical devices in the US. The level of risk posed by gamification remains ambiguous. While most apps showed only a weak link between the degree of gamification and potential risks, this link was stronger for those apps with a high degree of gamification or an immersive game experience.

Objectives: A study was undertaken to describe South African dietitians and key role players’ perceptions regarding their role in reporting food labelling legislation transgressions.Design: A multimethod study design was employed to explore a previously unstudied topic.Setting: Dietitians registered with the Health Professions Council of South Africa (HPCSA) together with key role players in food labelling in South Africa.Methods: Quantitative data were collected using a self-administered electronic questionnaire and qualitative data using a semi-structured interview guide. Quantitative data were analysed using Microsoft Excel and qualitative data using ATLAS.ti software. Data were analysed independently in the results section but integrated for interpretation of the findings.Results: In total, only 6% (n = 7) of the included dietitians (n = 126) reported food labelling transgressions, and 12% (n = 15) believed dietitians have a role to play in reporting transgressions. Interestingly, half of the included dietitians (50%, n = 63) stated they would report an identified transgression. Dietitians demonstrated a lack of awareness of the current food labelling regulations, with 43% wrongly identifying the draft regulation to consult. Almost all (99%, n = 125) of the included dietitians reported that their transgression reporting practices would improve if a clear guideline from the Department of Health: Directorate Food Control (DoH DFC) was available. Key role players (n = 8) cited enforcement issues and a perceived gap in dietitians’ understanding of legislation and reporting processes as barriers to reporting non-compliance. Key role players identified enablers such as awareness of regulations, contacts within the DoH DFC and familiarity with the reporting process for transgressions. They also provided insight on the proper procedure for reporting food labelling transgressions.Conclusion: The low prevalence of food labelling transgression reporting by dietitians stems from several barriers, including a perceived lack of confidence regarding the current regulation, awareness of the applicable legislation, uncertainty regarding the correct reporting procedure and scepticism that transgression reports will be acted upon. Regular communication regarding food and nutrition regulations and the development of an easy-to-use transgression reporting framework could support the implementation and impact of food labelling regulations in South Africa.

In response to the COVID-19 pandemic of 2020 and the ensuing public health crisis, thousands of higher education institutions (HEIs) worldwide have had to grapple with rapid pivots to emergency remote online learning modalities with relatively little time to prepare, and the need to maintain these modalities continues to extend longer than most institutions anticipated. However, this is not the first time HEIs have had to enact an emergency switch to online learning in a time of crisis, and there is perhaps much to be learned from examining the experiences of institutions that have been through this before. Resilient pedagogy is an emerging field in education, but it is intrinsically tied to online learning in a crisis insofar as it describes the ability to intentionally and effectively shift instructional tactics given a change in environment or context. Using a case study approach, this paper explores indicators of resilient pedagogy in emergency pivots to online learning following crisis situations--including the COVID-19 pandemic--in the United States, New Zealand, and South Africa. The data informing this research are qualitative, derived from interviews with faculty members and students in each higher education context.

The sparsity of post-translocation monitoring data for rehabilitated felids leaves a pressing gap in our current understanding of their integration into and use of novel landscapes. Remote monitoring tools such as GPS collars can provide crucial insights into animal movement behavior and habitat selection following translocation and assist in the decision-making process for rehabilitation and release sites. In January 2023, a young male ocelot was released on the Osa Peninsula, Costa Rica, after eight months of rehabilitation following a vehicle strike. Six months of post-translocation monitoring using a GPS and VHF-enabled collar revealed distinctive spatial patterns between the ocelot’s initial exploratory phase (~75 days) and subsequent residential period, as well as a selection for agricultural-forest matrix habitat over primary forest. We discuss the findings in terms of learning lessons for future post-release monitoring effects and provide insight into an individual’s patterns of habitat selection in an anthropogenically modified landscape.

Somfit is attached to patient’s forehead and combines channels specified for a pulse arterial tonometry (PAT)-based home sleep apnea testing (HSAT) device with the neurological signals. Somfit sleep staging deep learning algorithm is based on convolutional neural network architecture.Patients and Methods: One hundred and ten participants referred for sleep investigation with suspected or preexisting obstructive sleep apnea (OSA) in need of a review were enrolled into the study involving simultaneous recording of full overnight polysomnography (PSG) and Somfit data. The recordings were conducted at three centers in Australia. The reported statistics include standard measures of agreement between Somfit automatic hypnogram and consensus PSG hypnogram.Results: Overall percent agreement across five sleep stages (N1, N2, N3, REM, and wake) between Somfit automatic and consensus PSG hypnograms was 76.14 (SE: 0.79). The percent agreements between different pairs of sleep technologists’ PSG hypnograms varied from 74.36 (1.93) to 85.50 (0.64), with interscorer agreement being greater for scorers from the same sleep laboratory. The estimate of kappa between Somfit and consensus PSG was 0.672 (0.002). Percent agreement for sleep/wake discrimination was 89.30 (0.37). The accuracy of Somfit sleep staging algorithm varied with increasing OSA severity – percent agreement was 79.67 (1.87) for the normal subjects, 77.38 (1.06) for mild OSA, 74.83 (1.79) for moderate OSA and 72.93 (1.68) for severe OSA.Conclusion: Agreement between Somfit and PSG hypnograms was non-inferior to PSG interscorer agreement for a number of scorers, thus confirming acceptability of electrode placement at the center of the forehead. The directions for algorithm improvement include additional arousal detection, integration of motion and oximetry signals and separate inference models for individual sleep stages.Keywords: home sleep apnea testing, polysomnography, forehead electroencephalography, deep learning, interscorer agreement

Introduction Digital health tools can be beneficial in the care of patients with chronic conditions and have the potential for widespread impact as readily scalable and cost-effective health interventions. However, benefits are often contingent on users sustaining their engagement with these tools over time. Sustained engagement with digital health tools can be challenging, and high rates of attrition from digital interventions are common. Inflammatory Bowel Disease (IBD) and irritable bowel syndrome (IBS) are prominent gastrointestinal conditions resulting in significant burdens for individuals and society. Emerging evidence suggests digital health tools can be beneficial for IBD and IBS management; however, it is not clear what barriers and enablers are experienced by people living with these conditions to sustaining their engagement with these tools, when necessary. Such knowledge could inform the tailoring of new and existing digital health tools to the needs of people living with IBD and/or IBS. This study will seek to identify the barriers and enablers of sustained engagement with digital health tools among adults living with IBD and/or IBS.Methods and analysis We will conduct semistructured interviews with a purposive sample of approximately 30 adults (>18 years) who (a) reside in Canada, (b) self-report that they have been diagnosed with IBD and/or IBS, (c) have ever used a digital health tool (ie, any application/platform) to manage their condition and (d) are capable of providing informed consent. Interviews will be audio and video recorded and transcribed verbatim. Data will be coded deductively and barriers and enablers to sustained engagement will be categorised in accordance with the Theoretical Domains Framework. Data analysis will be verified by a patient research partner.Ethics and dissemination The study has been approved by the Ottawa Health Science Network Research Ethics Board. The findings will inform the codevelopment of strategies to overcome modifiable barriers and leverage identified enablers of sustained engagement with digital health tools for IBD and IBS care. These strategies can inform the design of new, or modifications to existing, digital health tools for IBD and IBS care where sustained engagement is desirable. Strategies will be compiled into a guidebook and disseminated via the Inflammation, Microbiome and Alimentation: Gastro-Intestinal and Neuropsychiatric Effects (IMAGINE) Strategy for Patient Oriented Research chronic disease network in Canada.

People who experience a stroke are at a higher risk of recurrent stroke when compared with people who have not had a stroke. Addressing modifiable risk factors like physical inactivity and poor diet has been shown to improve blood pressure, a leading contributor to stroke. However, survivors of stroke often experience challenges with accessing risk reduction services including long wait lists, difficulty with transportation, fatigue, impaired function, and diminished exercise capacity. Providing health interventions via a website can extend the reach when compared with programs that are only offered face to face or via real-time telehealth. Given global challenges of accessing secondary prevention programs, it is important to consider alternative ways that this information can be made available to survivors of stroke worldwide. Using the “design thinking” framework and drawing on principles of the integrated knowledge translation approach, we adapted 2 co-designed telehealth programs called i-REBOUND – Let’s get moving (physical activity intervention) and i-REBOUND – Eat for health (diet Intervention) to create the i-REBOUND after stroke website. The aim of this paper is to describe the systematic process undertaken to adapt resources from the telehealth delivered i-REBOUND – Let’s get moving and i-REBOUND – Eat for health programs to a website prototype with a focus on navigation requirements and accessibility for survivors of stroke. We engaged a variety of key stakeholders with diverse skills and expertise in areas of stroke recovery, research, and digital health. We established a governance structure, formed a consumer advisory group, appointed a diverse project team, and agreed on scope of the project. Our process of adaptation had the following 3 phases: (1) understand, (2) explore, (3) materialize. Our approach considered the survivor of stroke at the center of all decisions, which helped establish guiding principles related to our prototype design. Careful and iterative engagement with survivors of stroke together with the application of design thinking principles allowed us to establish the functional requirements for our website prototype. Through user testing, we were able to confirm the technical requirements needed to build an accessible and easy-to-navigate website catering to the unique needs of survivors of stroke. We describe the process of adapting existing content and co-creating new digital content in partnership with, and featuring, people who have lived experience of stroke. In this paper, we provide a road map for the steps taken to adapt resources from 2 telehealth-delivered programs to a website format that meets specific navigation and accessibility needs of survivors of stroke.

Summary: T cell surface CTLA4 sequesters the costimulatory ligands CD80 and CD86 on antigen-presenting cells (APCs) to prevent autoimmunity. Therapeutic immunosuppression by recombinant CTLA4-immunoglobulin (Ig) fusion proteins, including abatacept, is also attributed to CD80/CD86 blockade. Recent studies show that CTLA4-Ig binding to APC surface cis-CD80:PD-L1 complexes can release the inhibitory ligand PD-L1, but whether this contributes to T cell inhibition remains unclear. Here, we show that PD-L1 liberation by CTLA4-Ig is strictly limited, both in extent and context, relative to PD-L1-competing anti-CD80 antibodies. At APC surface CD80:PD-L1 ratios exceeding 2:1, CTLA4-Ig therapies fail to release PD-L1 regardless of their CD80 affinity. Additionally, introducing flexibility into CTLA4-Ig by modifying its rigid homodimer interface produces biologics that retain bivalent CD80 binding without dissociating cis-bound PD-L1. These findings demonstrate that CTLA4-Ig therapies liberate PD-L1 through a CD80 reorientation mechanism that imposes a strict context dependence to their PD-1 checkpoint agonism and resultant T cell inhibition.

Health care technologies have the ability to bridge or hinder equitable care. Advocates of digital mental health interventions (DMHIs) report that such technologies are poised to reduce the documented gross health care inequities that have plagued generations of people seeking care in the United States. This is due to a multitude of factors such as their potential to revolutionize access; mitigate logistical barriers to in-person mental health care; and leverage patient inputs to formulate tailored, responsive, and personalized experiences. Although we agree with the potential of DMHIs to advance health equity, we articulate several steps essential to mobilize and sustain meaningful forward progression in this endeavor, reflecting on decades of research and learnings drawn from multiple fields of expertise and real-world experience. First, DMHI manufacturers must build diversity, equity, inclusion, and belonging (DEIB) processes into the full spectrum of product evolution itself (eg, product design, evidence generation) as well as into the fabric of internal company practices (eg, talent recruitment, communication principles, and advisory boards). Second, awareness of the DEIB efforts—or lack thereof—in DMHI research trials is needed to refine and optimize future study design for inclusivity as well as proactively address potential barriers to doing so. Trials should incorporate thoughtful, inclusive, and creative approaches to recruitment, enrollment, and measurement of social determinants of health and self-identity, as well as a prioritization of planned and exploratory analyses examining outcomes across various groups of people. Third, mental health care advocacy, research funding policies, and local and federal legislation can advance these pursuits, with directives from the US Preventive Services Taskforce, National Institutes of Health, and Food and Drug Administration applied as poignant examples. For products with artificial intelligence/machine learning, maintaining a “human in the loop” as well as prespecified and adaptive analytic frameworks to monitor and remediate potential algorithmic bias can reduce the risk of increasing inequity. Last, but certainly not least, is a call for partnership and transparency within and across ecosystems (academic, industry, payer, provider, regulatory agencies, and value-based care organizations) to reliably build health equity into real-world DMHI product deployments and evidence-generation strategies. All these considerations should also extend into the context of an equity-informed commercial strategy for DMHI manufacturers and health care organizations alike. The potential to advance health equity in innovation with DMHI is apparent. We advocate the field’s thoughtful and evergreen advancement in inclusivity, thereby redefining the mental health care experience for this generation and those to come.

Abstract Necroptosis is a lytic form of regulated cell death reported to contribute to inflammatory diseases of the gut, skin and lung, as well as ischemic-reperfusion injuries of the kidney, heart and brain. However, precise identification of the cells and tissues that undergo necroptotic cell death in vivo has proven challenging in the absence of robust protocols for immunohistochemical detection. Here, we provide automated immunohistochemistry protocols to detect core necroptosis regulators – Caspase-8, RIPK1, RIPK3 and MLKL – in formalin-fixed mouse and human tissues. We observed surprising heterogeneity in protein expression within tissues, whereby short-lived immune barrier cells were replete with necroptotic effectors, whereas long-lived cells lacked RIPK3 or MLKL expression. Local changes in the expression of necroptotic effectors occurred in response to insults such as inflammation, dysbiosis or immune challenge, consistent with necroptosis being dysregulated in disease contexts. These methods will facilitate the precise localisation and evaluation of necroptotic signaling in vivo.

Abstract Improving the kinetics and selectivity of CO2/CO electroreduction to valuable multi-carbon products is a challenge for science and is a requirement for practical relevance. Here we develop a thiol-modified surface ligand strategy that promotes electrochemical CO-to-acetate. We explore a picture wherein nucleophilic interaction between the lone pairs of sulfur and the empty orbitals of reaction intermediates contributes to making the acetate pathway more energetically accessible. Density functional theory calculations and Raman spectroscopy suggest a mechanism where the nucleophilic interaction increases the sp 2 hybridization of CO(ad), facilitating the rate-determining step, CO* to (CHO)*. We find that the ligands stabilize the (HOOC–CH2)* intermediate, a key intermediate in the acetate pathway. In-situ Raman spectroscopy shows shifts in C–O, Cu–C, and C–S vibrational frequencies that agree with a picture of surface ligand-intermediate interactions. A Faradaic efficiency of 70% is obtained on optimized thiol-capped Cu catalysts, with onset potentials 100 mV lower than in the case of reference Cu catalysts.

People tend to feel negatively when they are ignored by a conversation partner attending to their phone (i.e. ‘phubbing’). We investigated how quickly people recover in an experiment where participants provided intensive real-time ratings of their mood during a simulated conversation with a partner who engaged in either no phubbing, a single phub, or repeated phubbing. Drawing on ostracism theories, we hypothesized and found that a single phub induces negative affect, d ≈ 0.40, and people begin recovering immediately. However, repeated phubbing causes increasingly negative affect, d ≈ 1.20, with a pattern of partial recovery between phubs. People quickly feel bad, but recover within seconds, unless repeated phubbing interrupts the recovery, and produces increasingly negative affect.

IntroductionNontraumatic subarachnoid hemorrhage (ntSAH) often results from a ruptured aneurysm and correlates with significant morbidity and mortality, particularly among the older population. Despite its impact, limited comprehensive studies evaluate the longitudinal trends in ntSAH-related mortality in older adults in the United States (US).MethodsThe authors conducted a retrospective analysis using the CDC WONDER database from 1999 to 2020, analyzing Multiple Cause-of-Death Public Use death certificates to identify ntSAH as a contributing factor in the death of adults aged 65 years and older. We calculated age-adjusted mortality rates (AAMR) and annual percent change (APC) to examine trends across demographic variables such as sex, race/ethnicity, urbanization, and states/census region.ResultsA total of 78,260 ntSAH-related deaths (AAMR 8.50 per 100,000 individuals) occurred among older adults in the US from 1999 to 2020. The overall AAMR for ntSAH decreased from 9.98 in 1999 to 8.67 in 2020 with an APC of −0.7% [95% CI (−1.0, −0.3)]. However, the authors observed a noticeable rise from 2013 to 2020 with an APC of 1.7% [95% CI (0.8, 2.6)]. Sex, racial, and regional disparities were evident with higher mortality rates for ages 85 or greater (crude mortality rate 16.6), women (AAMR 9.55), non-Hispanic Asian or Pacific Islander (AAMR 12.5), and micropolitan areas (AAMR 8.99), and Western US (AAMR 8.65).ConclusionMortality from ntSAH increases with age, affects women disproportionately, and occurs more often in an inpatient setting. These findings necessitate targeted, multi-dimensional health policies and clinical interventions. Specialties beyond neurosurgery can utilize this data for improved risk stratification and early treatment. Policymakers should focus on equitable resource allocation and community-level interventions to mitigate these trends effectively.

Background PP‐007 is a polyethylene glycol (PEG)ylated bovine carboxyhemoglobin gas transfer molecule with pleotropic cytoprotective effects, vasodilatation, plasma expansion, and optimization of oxygen delivery. Rodent middle cerebral artery occlusion models have demonstrated that PP‐007 increases blood flow in the collateral circulation and reduces final infarct volumes, supporting a potential role as neuroprotective agent in acute ischemic stroke. We aim to evaluate the safety and feasibility of PP‐007 as an adjunctive treatment to mechanical thrombectomy (MT) in patients with stroke secondary to large vessel occlusion. Methods HEMERA‐1 (CarboxyHEMoglobin OxygEn delivery for Revascularization in Acute Stroke) was a multicenter, prospective, randomized, controlled phase 1 clinical trial. Anterior circulation large vessel occlusion patients were assigned in a 3:1 ratio to receive either PP‐007 (320 mg/kg: 30 min bolus followed by 2‐h infusion) plus MT or MT alone within 24 hours after symptom onset. Comprehensive safety evaluation was performed by independent Data Monitoring Safety Board and Imaging Core Lab. Results From October 1, 2021 to June 30, 2022, a total of 17 patients were recruited. Age, baseline National Institutes of Health Stroke Scale score, and Alberta Stroke Program Early CT Score were 74.8±12.7 years, 17.3±4.2, and 7.9±1.8, respectively. Twelve patients were randomized to PP‐007 plus MT, 1 was randomized but not treated, 4 patients were randomized to MT alone. Recanalization of the occluded vessel was achieved in all patients. A transient systolic blood pressure increase (20–40 mm Hg) during the bolus was observed in all PP‐007 patients without any clinical consequences. There were no other safety concerns. Conclusion No significant safety concerns were identified for the adjunctive use of PP‐007 in patients undergoing MT. (The study was funded by Prolong Pharmaceuticals.

Objective Pragmatic methodologies, often termed rapid-learning, are being pursued that can match the pace of innovation in radiotherapy and generate evidence from the real-world treatment setting. It is important to understand the feasibility of implementing such pragmatic approaches before their application in practice. This study investigated key professional stakeholders’ perceptions and opinions of rapid-learning and real-world data (RWD).Methods and analysis Twenty-three interviews were conducted with key professional stakeholders based across five UK radiotherapy cancer centres. Centres varied in size and reflected different healthcare environments. Data were collected between December 2022 and May 2023, and analysed using inductive thematic analysis.Results Four themes were generated: (1) the alignment of rapid-learning methodologies with the reality of practice, (2) concerns related to the variability of RWD, (3) the maturity of data infrastructures and capacity for rapid-learning and (4) further support, education and evidence needed to convince stakeholders to adopt rapid-learning approaches.Conclusion The potential of rapid-learning to help address evidence gaps in radiotherapy development was positively received by different professional stakeholders. However, the effectiveness of rapid-learning was viewed as being highly dependent on the collection of quality data in the routine setting, while the variable set-up at different cancer centres is also likely to be a key challenge for potential implementation. Developing data infrastructures to improve data interoperability was considered crucial for rapid-learning implementation, along with method clarity, educational support and training for radiotherapy teams.

Objective Coeliac disease (CD) diagnosis generally depends on histological examination of duodenal biopsies. We present the first study analysing the concordance in examination of duodenal biopsies using digitised whole-slide images (WSIs). We further investigate whether the inclusion of immunoglobulin A tissue transglutaminase (IgA tTG) and haemoglobin (Hb) data improves the interobserver agreement of diagnosis.Design We undertook a large study of the concordance in histological examination of duodenal biopsies using digitised WSIs in an entirely virtual reporting setting. Our study was organised in two phases: in phase 1, 13 pathologists independently classified 100 duodenal biopsies (40 normal; 40 CD; 20 indeterminate enteropathy) in the absence of any clinical or laboratory data. In phase 2, the same pathologists examined the (re-anonymised) WSIs with the inclusion of IgA tTG and Hb data.Results We found the mean probability of two observers agreeing in the absence of additional data to be 0.73 (±0.08) with a corresponding Cohen’s kappa of 0.59 (±0.11). We further showed that the inclusion of additional data increased the concordance to 0.80 (±0.06) with a Cohen’s kappa coefficient of 0.67 (±0.09).Conclusion We showed that the addition of serological data significantly improves the quality of CD diagnosis. However, the limited interobserver agreement in CD diagnosis using digitised WSIs, even after the inclusion of IgA tTG and Hb data, indicates the importance of interpreting duodenal biopsy in the appropriate clinical context. It further highlights the unmet need for an objective means of reproducible duodenal biopsy diagnosis, such as the automated analysis of WSIs using artificial intelligence.

Abstract Introduction Radiation therapy treatment for breast cancer may negatively impact patients' health‐related quality of life. Evidence suggests exercise and nutrition interventions may be beneficial to patients experiencing compromised health‐related quality of life. This study investigates whether radiation oncology practitioners support the implementation of a tailored exercise and nutrition intervention for patients and explores their interest in participating in training for exercise and nutrition as interventions. Methods Data were collected by an online survey, deployed to public and private radiation oncology departments, across three Australian states (Australian Capital Territory, New South Wales, Queensland). The survey was completed between June and August 2020. Radiation oncologists, radiation oncology registrars, radiation therapists and radiation oncology nurses completed the survey. The survey included demographics, patient assessment and questions regarding the radiation oncology practitioners' use of exercise and nutrition as interventions. Results Of 192 practitioners targeted, 76 completed the survey, for a response rate of 40%. Of 76 respondents, 42% ‘sometimes’ recommended exercise and 41% ‘sometimes’ recommended nutrition as health‐related quality of life interventions to their patients. The majority indicated they would benefit from more training in these subjects, with 58% for exercise and 55% for nutrition. 47 per cent of respondents thought patients would benefit from a tailored exercise and nutrition programme and 62% agreed they would refer patients to a programme if it were available. Conclusions Radiation oncology practitioners reported they need training in exercise and nutrition to better understand how this can benefit the health‐related quality of life of breast cancer patients. Also, the findings indicate that if such an exercise and nutrition intervention were readily available, practitioners would refer patients who may benefit from this intervention.

Background: Mitochondria are considered the powerhouse of cells, and skeletal muscle cells are no exception. However, information regarding muscle mitochondria from different species is limited. Methods: Different muscles from cattle, pigs and chickens were analyzed for mitochondrial DNA (mtDNA), protein and oxygen consumption. Results: Bovine oxidative muscle mitochondria contain greater mtDNA (p < 0.05), protein (succinate dehydrogenase, SDHA, p < 0.01; citrate synthase, CS, p < 0.01; complex I, CI, p < 0.05), and oxygen consumption (p < 0.01) than their glycolytic counterpart. Likewise, porcine oxidative muscle contains greater mtDNA (p < 0.01), mitochondrial proteins (SDHA, p < 0.05; CS, p < 0.001; CI, p < 0.01) and oxidative phosphorylation capacity (OXPHOS, p < 0.05) in comparison to glycolytic muscle. However, avian oxidative skeletal muscle showed no differences in absolute mtDNA, SDHA, CI, complex II, lactate dehydrogenase, or glyceraldehyde 3 phosphate dehydrogenase compared to their glycolytic counterpart. Even so, avian mitochondria isolated from oxidative muscles had greater OXPHOS capacity (p < 0.05) than glycolytic muscle. Conclusions: These data show avian mitochondria function is independent of absolute mtDNA content and protein abundance, and argue that multiple levels of inquiry are warranted to determine the wholistic role of mitochondria in skeletal muscle.

Introduction: Food literacy (FL) is a rapidly emerging area of research that provides a framework to explain the interplay of food-related skills, beliefs, knowledge and practises that contribute to nutritional health and wellbeing. This review is the first to scope the current literature for FL interventions, assess their characteristics against the components provided in the most widely cited definition of FL. and describe their characteristics to identify gaps in the literature. Methods: This review scopes original articles describing FL interventions in the Medline, CINAHL, ProQuest Education, Web of Science and AMED databases up to August 2023. Results: Despite the heterogeneity between all seven included studies, they all demonstrated some improvements in their FL outcome measures alongside dietary intake (DI), with the greatest improvements seen in studies that employed a FL theoretical framework in intervention design. Populations at high risk of food insecurity, such as university students and people living in disadvantaged areas, were the main targets of FL interventions. Conclusion: The minimal inclusion of FL theory amongst interventions led to an overall poor coverage of essential FL components, indicating researchers should aim to design future FL interventions with a FL theoretical framework.

Summary: Hypoxia-inducible factor 1 (HIF-1) is a transcriptional activator that mediates cellular adaptation to decreased oxygen availability. HIF-1 recruits chromatin-modifying enzymes leading to changes in histone acetylation, citrullination, and methylation at target genes. Here, we demonstrate that hypoxia-inducible gene expression in estrogen receptor (ER)-positive MCF7 and ER-negative SUM159 human breast cancer cells requires the histone H2A/H2B chaperone facilitates chromatin transcription (FACT) and the H2B ubiquitin ligase RING finger protein 20/40 (RNF20/40). Knockdown of FACT or RNF20/40 expression leads to decreased transcription initiation and elongation at HIF-1 target genes. Mechanistically, FACT and RNF20/40 are recruited to hypoxia response elements (HREs) by HIF-1 and stabilize binding of HIF-1 (and each other) at HREs. Hypoxia induces the monoubiquitination of histone H2B at lysine 120 at HIF-1 target genes in an HIF-1-dependent manner. Together, these findings delineate a cooperative molecular mechanism by which FACT and RNF20/40 stabilize multiprotein complex formation at HREs and mediate histone ubiquitination to facilitate HIF-1 transcriptional activity.

Researchers have highlighted the need for ongoing design pedagogy reform in order to reflect worldwide transformations, changing socio-cultural contexts and the expanding scope of design practice. New pedagogical models have emerged in architectural education that incorporate stakeholder perspectives and encourage community engagement. "Participatory Design" (PD) methodology has become a promising pedagogical approach to engage diverse stakeholders and communities in the design process. The twofold goal of this article is to describe and categorise student learning experiences in an architecture studio and to delineate the benefits of applying PD methodology to architecture studio pedagogy. Students from a graduate level integrated architectural studio participated in the study and led a series of three participatory co-creation activities with diverse stakeholders who were planned for the front, middle and backend of the design process. Observations, questionnaires and interviews were used to describe and categorise student learning experiences as well as determine the benefits of integrating PD methodology into a design studio. The study results demonstrate that participatory activities positively impact student learning experiences as well as greatly enhance student empathy for stakeholders, thus integrating the social and technical aspects of their experience and demonstrating the importance of stakeholder engagement in collective and creative experimentation.

Despite the perceived rarity of mid-semester faculty changes, there is a shortage of literature to guide administrators and faculty on best practices for handing the dilemmas associated with mid-semester faculty changes. This is particularly concerning given the uncertainty of situations like the COVID-19 global pandemic and recent research that finds that future extreme epidemics are likely to happen. This paper seeks to answer two questions (1) What can faculty and administrators do to prepare students who are experiencing a mid-semester faculty change, and (2) What procedures and processes are in place to assist the incoming faculty? Data were collected through a survey of students who had underwent a mid-semester faculty change and interviews with administrators who deal with personnel issues like this one. The data suggest faculty should first meet with students to assess their progress before jumping into an established lesson plan (the opposite of how faculty normally prepare to teach a class). Clear communication about expectations, organization of the course materials, and instructor flexibility was identified as keys to student success during a teaching disruption. These findings align with decades of research on teaching and learning. Administrators should create contingency plans that go beyond the personnel transaction and that help faculty quickly prepare for a transition that is student focused. More research is needed to identify the best administrative processes and procedures to assist faculty in a smooth transition when taking over a course mid-semester.
