Project DINE: Addressing Disparities in Nutrition and Maternal Mortality and Morbidity through Nutrition and Father Engagement.

This study assessed the outcomes of an intervention (Project DINE) that added nutrition and breastfeeding education to Healthy Start programs in Georgia for a sample of Black expecting parents. Using a community-based participatory approach and a 2 × 2 randomized cluster factorial design, three of six Healthy Start sites were intervention sites. Participants completed the Adult Food and Physical Activity Behavior Questionnaire and a breastfeeding education survey pre- and post-intervention. Paired t-tests determined that there was an improvement in overall self-reported diet quality among the expecting couples (n=61; p = .025). Breastfeeding survey data showed that the percentage of correct answers increased from 78% to 84% (n=89; p=.0009) for all participants. Qualitative data were also collected through open-ended responses on the breastfeeding post-test (n=66) and focus groups with fathers (n=10). This project demonstrates the need for nutrition and breastfeeding education for both expecting parents during pregnancy to improve maternal health.

Axillary-Subclavian Venous Thrombosis following a weightlifting injury in an elderly patient: a case report.

Background: Axillary-subclavian venous thrombosis (ASVT) is a type of upper extremity deep vein thrombosis (UEDVT). UEDVTs are classified as either primary or secondary depending on their etiology. Although uncommon, clinicians should be aware of the clinical presentation of UEDVT as timely diagnosis and early treatment is critical in preventing possible post-thrombotic complications. Case presentation: We report a rare case of axillary-subclavian and internal jugular vein thrombosis in the absence of clear risk factors in a 78-year-old male weightlifter who presented to the office with two-week duration of left upper extremity pain and swelling following strenuous exercise at the gym. Summary: The combination of unusual thrombi location, in addition to the unusual absence of existing thoracic-outlet compression or indwelling medical hardware, makes our case of UEDVT especially uncommon. Clinicians should be aware of this rare disease due to the debilitating effects both in the short and long term.

Factors that influence participation in physical activity for people with bipolar disorder: a synthesis of qualitative evidence.

BACKGROUND: Mental health problems contribute significantly to the overall disease burden worldwide and are major causes of disability, suicide, and ischaemic heart disease. People with bipolar disorder report lower levels of physical activity than the general population, and are at greater risk of chronic health conditions including cardiovascular disease and obesity. These contribute to poor health outcomes. Physical activity has the potential to improve quality of life and physical and mental well-being. OBJECTIVES: To identify the factors that influence participation in physical activity for people diagnosed with bipolar disorder from the perspectives of service users, carers, service providers, and practitioners to help inform the design and implementation of interventions that promote physical activity. SEARCH METHODS: We searched MEDLINE, PsycINFO, and eight other databases to March 2021. We also contacted experts in the field, searched the grey literature, and carried out reference checking and citation searching to identify additional studies. There were no language restrictions. SELECTION CRITERIA: We included qualitative studies and mixed-methods studies with an identifiable qualitative component. We included studies that focused on the experiences and attitudes of service users, carers, service providers, and healthcare professionals towards physical activity for bipolar disorder. DATA COLLECTION AND ANALYSIS: We extracted data using a data extraction form designed for this review. We assessed methodological limitations using a list of predefined questions. We used the "best fit" framework synthesis based on a revised version of the Health Belief Model to analyse and present the evidence. We assessed methodological limitations using the CASP Qualitative Checklist. We used the GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) guidance to assess our confidence in each finding. We examined each finding to identify factors to inform the practice of health and care professionals and the design and development of physical activity interventions for people with bipolar disorder. MAIN RESULTS: We included 12 studies involving a total of 592 participants (422 participants who contributed qualitative data to an online survey, 170 participants in qualitative research studies). Most studies explored the views and experiences of physical activity of people with experience of bipolar disorder. A number of studies also reported on personal experiences of physical activity components of lifestyle interventions. One study included views from family carers and clinicians. The majority of studies were from high-income countries, with only one study conducted in a middle-income country. Most participants were described as stable and had been living with a diagnosis of bipolar disorder for a number of years. We downgraded our confidence in several of the findings from high confidence to moderate or low confidence, as some findings were based on only small amounts of data, and the findings were based on studies from only a few countries, questioning the relevance of these findings to other settings. We also had very few perspectives of family members, other carers, or health professionals supporting people with bipolar disorder. The studies did not include any findings from service providers about their perspectives on supporting this aspect of care. There were a number of factors that limited people's ability to undertake physical activity. Shame and stigma about one's physical appearance and mental health diagnosis were discussed. Some people felt their sporting skills/competencies had been lost when they left school. Those who had been able to maintain exercise through the transition into adulthood appeared to be more likely to include physical activity in their regular routine. Physical health limits and comorbid health conditions limited activity. This included bipolar medication, being overweight, smoking, alcohol use, poor diet and sleep, and these barriers were linked to negative coping skills. Practical problems included affordability, accessibility, transport links, and the weather. Workplace or health schemes that offered discounts were viewed positively. The lack of opportunity for exercise within inpatient mental health settings was a problem. Facilitating factors included being psychologically stable and ready to adopt new lifestyle behaviours. There were positive benefits of being active outdoors and connecting with nature. Achieving balance, rhythm, and routine helped to support mood management. Fitting physical activity into a regular routine despite fluctuating mood or motivation appeared to be beneficial if practised at the right intensity and pace. Over- or under-exercising could be counterproductive and accelerate depressive or manic moods. Physical activity also helped to provide a structure to people's daily routines and could lead to other positive lifestyle benefits. Monitoring physical or other activities could be an effective way to identify potential triggers or early warning signs. Technology was helpful for some. People who had researched bipolar disorder and had developed a better understanding of the condition showed greater confidence in managing their care or providing care to others. Social support from friends/family or health professionals was an enabling factor, as was finding the right type of exercise, which for many people was walking. Other benefits included making social connections, weight loss, improved quality of life, and better mood regulation. Few people had been told of the benefits of physical activity. Better education and training of health professionals could support a more holistic approach to physical and mental well-being. Involving mental health professionals in the multidisciplinary delivery of physical activity interventions could be beneficial and improve care. Clear guidelines could help people to initiate and incorporate lifestyle changes. AUTHORS' CONCLUSIONS: There is very little research focusing on factors that influence participation in physical activity in bipolar disorder. The studies we identified suggest that men and women with bipolar disorder face a range of obstacles and challenges to being active. The evidence also suggests that there are effective ways to promote managed physical activity. The research highlighted the important role that health and care settings, and professionals, can play in assessing individuals' physical health needs and how healthy lifestyles may be promoted. Based on these findings, we have provided a summary of key elements to consider for developing physical activity interventions for bipolar disorder.

Prevalence and risk factors for long COVID among adults in Scotland using electronic health records: a national, retrospective, observational cohort study.

Background: Long COVID is a debilitating multisystem condition. The objective of this study was to estimate the prevalence of long COVID in the adult population of Scotland, and to identify risk factors associated with its development. Methods: In this national, retrospective, observational cohort study, we analysed electronic health records (EHRs) for all adults (≥18 years) registered with a general medical practice and resident in Scotland between March 1, 2020, and October 26, 2022 (98-99% of the population). We linked data from primary care, secondary care, laboratory testing and prescribing. Four outcome measures were used to identify long COVID: clinical codes, free text in primary care records, free text on sick notes, and a novel operational definition. The operational definition was developed using Poisson regression to identify clinical encounters indicative of long COVID from a sample of negative and positive COVID-19 cases matched on time-varying propensity to test positive for SARS-CoV-2. Possible risk factors for long COVID were identified by stratifying descriptive statistics by long COVID status. Findings: Of 4,676,390 participants, 81,219 (1.7%) were identified as having long COVID. Clinical codes identified the fewest cases (n = 1,092, 0.02%), followed by free text (n = 8,368, 0.2%), sick notes (n = 14,469, 0.3%), and the operational definition (n = 64,193, 1.4%). There was limited overlap in cases identified by the measures; however, temporal trends and patient characteristics were consistent across measures. Compared with the general population, a higher proportion of people with long COVID were female (65.1% versus 50.4%), aged 38-67 (63.7% versus 48.9%), overweight or obese (45.7% versus 29.4%), had one or more comorbidities (52.7% versus 36.0%), were immunosuppressed (6.9% versus 3.2%), shielding (7.9% versus 3.4%), or hospitalised within 28 days of testing positive (8.8% versus 3.3%%), and had tested positive before Omicron became the dominant variant (44.9% versus 35.9%). The operational definition identified long COVID cases with combinations of clinical encounters (from four symptoms, six investigation types, and seven management strategies) recorded in EHRs within 4-26 weeks of a positive SARS-CoV-2 test. These combinations were significantly (p < 0.0001) more prevalent in positive COVID-19 patients than in matched negative controls. In a case-crossover analysis, 16.4% of those identified by the operational definition had similar healthcare patterns recorded before testing positive. Interpretation: The prevalence of long COVID presenting in general practice was estimated to be 0.02-1.7%, depending on the measure used. Due to challenges in diagnosing long COVID and inconsistent recording of information in EHRs, the true prevalence of long COVID is likely to be higher. The operational definition provided a novel approach but relied on a restricted set of symptoms and may misclassify individuals with pre-existing health conditions. Further research is needed to refine and validate this approach. Funding: Chief Scientist Office (Scotland), Medical Research Council, and BREATHE.

Simulation in New Zealand: what have you done for me lately? New Zealand Association for Simulation in Healthcare (NZASH) white paper.

Medical simulation has become an integral aspect of modern healthcare education and practice. It has evolved to become an essential aspect of teaching core concepts and skills, common and rare presentations, algorithms and protocols, communication, interpersonal and teamworking skills and testing new equipment and systems. Simulation-based learning (SBL) is useful for the novice to the senior clinician. Healthcare is a complex adaptive system built from very large numbers of mutually interacting subunits (e.g., different professions, departments, equipment). These subunits generate multiple repeated interactions that have the potential to result in rich, collective behaviour that feeds back into the organisation. There is a unique opportunity in New Zealand with the formation of Te Whatu Ora - Health New Zealand and Te Aka Whai Ora - Maori Health Authority and the reorganisation of the healthcare system. This viewpoint is a white paper for the integration of SBL into our healthcare system. We describe our concerns in the current system and list our current capabilities. The way SBL could be implemented in pre- and post-registration phases of practice are explored as well as the integration of communication and culture. Interprofessional education has been shown to improve outcomes and is best done with an interprofessional simulation curriculum. We describe ways that simulation is currently used in our system and describe other uses such as quality improvement, safety and systems engineering and integration. The aim of this viewpoint is to alert Te Whatu Ora and Te Aka Whai Ora of the existing infrastructure of the simulation community in New Zealand and encourage them to invest in its future.

The patient journey in Chronic Obstructive Pulmonary Disease (COPD): a human factors qualitative international study to understand the needs of people living with COPD.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common condition that causes irreversible airway obstruction. Fatigue and exertional dyspnoea, for example, have a detrimental impact on the patient's daily life. Current research has revealed the need to empower the patient, which can result in not only educated and effective decision-making, but also a considerable improvement in patient satisfaction and treatment compliance. The current study aimed to investigate the perspectives and requirements of people living with COPD to possibly explore new ways to manage their disease. METHODS: Adults with COPD from 8 European countries were interviewed by human factor experts to evaluate their disease journey through the gathering of information on the age, performance, length, and impact of diagnosis, symptoms progression, and family and friends' reactions. The assessment of present symptoms, services, and challenges was performed through a 90-min semi-structured interview. To identify possible unmet needs of participants, a generic thematic method was used to explore patterns, themes, linkages, and sequences within the data collected. Flow charts and diagrams were created to communicate the primary findings. Following analysis, the data was consolidated into cohesive insights and conversation themes relevant to determining the patient's unmet needs. RESULTS: The 62, who voluntarily accepted to be interviewed, were patients (61% females, aged 32-70 years) with a COPD diagnosis for at least 6 months with stable symptoms of different severity. The main challenges expressed by the patients were the impact on their lifestyle, reduced physical activity, and issues with their mobility. About one-fourth had challenges with their symptoms or medication including difficulty in breathing. Beyond finding a cure for COPD was the primary goal for patients, their main needs were to receive adequate information on the disease and treatments, and to have adequate support to improve physical activity and mobility, helpful both for patients and their families. CONCLUSIONS: These results could aid in the creation of new ideas and concepts to improve our patient's quality of life, encouraging a holistic approach to people living with COPD and reinforcing the commitment to understanding their needs.

'Lifts your spirits, lifts your mind': A co-produced mixed-methods exploration of the benefits of green and blue spaces for mental wellbeing.

INTRODUCTION: Mental health problems are a considerable public health issue and spending time in nature has been promoted as a way to access a range of psychological benefits leading to the development of nature-based interventions for people with severe and enduring mental health problems. Less, however, is understood about the potential benefits and efficacy of day-to-day routine access to outdoor green and blue spaces for mental health service users. METHODS: Using a mixed-methods design between April and October 2021, we explored the benefits and barriers to spending time outdoors with a purposive sample of mental health service users (N = 11) using qualitative interviews and an online general population survey (N = 1791). Qualitative evidence highlighted the restorative benefits of nature and identified a number of barriers associated with fears around personal safety, social anxiety, fatigue and lack of motivation. COVID-19 had also restricted access to green and blue spaces. Having social contact and support encouraged people to spend time outdoors. In the quantitative survey, self-report and standardised measures (the Patient Health Questionnaire and the Warwick-Edinburgh Wellbeing Scale) were used to assess past and current mental wellbeing. FINDINGS: Statistically significant differences were found between wellbeing and the use of green and blue spaces. Those with mental health problems spent time outdoors because they: felt guilty; wanted to reduce their anxiety; or rely on someone for encouragement. Those without mental health problems endorsed more positively framed reasons including relaxation, improving physical health or getting exercise. Barriers for people with mental health problems involved safety concerns, feeling anxious and having a poor self-image. These findings give insight into motivations for an outdoor activity to help inform the design of public mental health interventions. CONCLUSION: Further work is required to improve access and safety to promote the benefits of green and blue spaces for everyone. PATIENT OR PUBLIC CONTRIBUTION: The research team included expert experienced researchers with a mental health service provider (Praxis Care) and they were involved in the development of the research idea, funding application, design, data collection, analysis, writing up and dissemination activities.

Perspectives on relative energy deficiency in sport (RED-S): A qualitative case study of athletes, coaches and medical professionals from a super league netball club.

BACKGROUND: Research into relative energy deficiency in sport (RED-S) has increased substantially over recent years given the impact on athletes' health and performance. Most studies have considered sports that place emphasis on the aesthetics, endurance, or weight-restriction. Fewer studies exist in team sports. Netball is a team sport yet to be explored despite players potentially being at risk of RED-S given the high training volumes, sporting culture, internal and external pressures, and small network of coaches and medical professionals. A qualitative case study was used to explore the perspective of athletes, coaches, and medical professionals on RED-S. METHODS: Semi-structured interviews were conducted with 13 players, 4 coaches and 4 medical professionals affiliated to a Super League club. Interviews were recorded and transcribed verbatim. The data was analysed using thematic analysis. RESULTS: Five main themes were identified in this study. Awareness of RED-S amongst athletes and coaches was generally inadequate whereas medical professionals had some awareness of RED-S. Some athletes used contraception to reduce discomfort/pain during menstruation whilst others expressed concerns around long-term contraceptive use and previous menstrual cycle disturbance. Sporting demands, individual and contextual factors, and a preoccupation with body image were associated with nutritional restriction, whilst appearance was a source of internal and external pressure. External pressures also extended to coaches, assessments/feedback, social media, and commentary. Strategies suggested to reduce the risk of RED-S included "hard hitting cases", multidisciplinary team involvement, and support from the governing body. CONCLUSION: The findings of this study provide insight into factors potentially associated with the risk of RED-S from an athletes, coaches, and medical professional perspective. This insight can be used to increase overall awareness of RED-S in key stakeholders as well as improve the recognition for the pressures netball athletes face that might alter the level of risk.

Effects of bariatric surgery and dietary intervention on insulin resistance and appetite hormones over a 3 year period.

To examine an impact of three types of bariatric surgery compared with dietary intervention (DIET), on concurrent changes in Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) and appetite hormones over 3 years. Fifty-five adults were studied during phase of weight loss (0-12 months) and during weight stability (12-36 months) post intervention. Measurements of HOMA-IR, fasting and postprandial PYY and GLP1, adiponectin, CRP, RBP4, FGF21 hormones and dual-Xray absorptiometry were performed throughout the study. All surgical groups achieved significant reductions in HOMA-IR with greatest difference between Roux-en-Y gastric bypass and DIET (- 3.7; 95% CI - 5.4, - 2.1; p = 0.001) at 12-36 months. Initial (0-12 months) HOMA-IR values were no different to DIET after adjustment for the lost weight. During 12-36 months, after controlling for treatment procedure and weight, for every twofold increase in postprandial PYY and adiponectin, HOMA-IR decreased by 0.91 (95% CI - 1.71, - 0.11; p = 0.030) and by 0.59 (95% CI - 1.10, - 0.10; p = 0.023) respectively. Initial, non-sustained changes in RBP4 and FGF21 were not associated with HOMA-IR values. While initial rapid weight loss reduces insulin resistance, the enhanced secretions of PYY and adiponectin may contribute to weight-independent improvements in HOMA-IR during weight stability.Clinical trial registration: Australian New Zealand Clinical Trials Registry (ANZCTR): ACTRN12613000188730.

Cetacean responses to violation of expectation paradigm in a free-swim context.

The investigation of individual responses to unexpected stimuli or outcomes provides insights into basic cognitive processes, such as mental representations, emotional states of surprise, and detections of anomalies. Three experiments using a violation of expectation paradigm were conducted with 12 belugas and 17 bottlenose dolphins in managed care to test two classes of stimuli (humans and objects) in manipulated sequences of familiar and unfamiliar humans (Study 1, trainers and strangers), familiar and unfamiliar objects (Study 2, typical enrichment devices and new objects), and finally objects and humans (Study 3). Gaze durations were assessed for each condition in a given study during free-swim contexts. The results supported previous findings that visual stimuli, regardless of class, were stimulating and intriguing for both belugas and bottlenose dolphins. Belugas were more likely to gaze longer at human and object stimuli and tended to gaze longer at unexpected experiences than control or expected experiences. Bottlenose dolphins showed similar trends except when objects were involved. Individual variability was present for both species with some individuals showing stronger patterns of responses for expected experiences than others. After 2 years of intermittent experiments, belugas and bottlenose dolphins in managed care maintained their curiosity about visual stimuli, for which they received no primary reinforcement. Investigating responses to unexpected stimuli with animals in managed care may provide insight into how these animals respond to biologically relevant conditions, such as boat presence, predators, and unfamiliar conspecifics.

The role of community pharmacists in delivering interventions for osteoporosis: A systematic review.

BACKGROUND: Osteoporosis is a major public health concern, given that disease prevalence is expected to substantially increase due to the aging population. Community pharmacists can play a key role in the identification and management of chronic diseases. OBJECTIVES: The purpose of this systematic review was to present an overview of the literature on the role of community pharmacists in providing osteoporosis interventions to patients. The secondary objective was to assess the impact of these interventions on patient outcomes. METHODS: A literature search was conducted in Embase, CINAHL, Scopus, MEDLINE, and Web of Science from database inception to March 2021. The search was limited to human studies in the English language. Primary studies were included if they described or assessed a patient-directed osteoporosis intervention conducted by community pharmacists. The following data were extracted and tabulated: citation, study location, study design, subject, number of participants, nature of intervention, classification of intervention, outcome measures, measurement methods, findings, and effect. Risk of bias was assessed using the Cochrane Risk of Bias tool for randomized trials (RoB 2) and Risk of Bias in Non-randomized Studies (ROBINS-I). RESULTS: Twenty-one studies were included in this review. The main interventions were education, screening, and medication management. Nineteen of these studies reported patient outcomes, all yielding positive outcomes. Outcomes included increased physician follow-up, risk factor reduction, increased osteoporosis knowledge, increased medication adherence, identification of medication-related problems, and positive patient-reported experience measures (PREMs). Three studies were considered to have a moderate risk of bias, whereas the remaining 18 studies had a high risk of bias. CONCLUSION: There is some evidence that pharmacist-led osteoporosis interventions have a positive impact on patient outcomes. More high-quality studies using objective outcome measures are needed to determine whether this translates into clinical outcomes such as decreased hospitalization and fractures.

Resource requirements for ecosystem conservation: A combined industrial and natural ecology approach to quantifying natural capital use in nature.

Socioeconomic demand for natural capital is causing catastrophic losses of biodiversity and ecosystem functionality, most notably in regions where socioeconomic-and eco-systems compete for natural capital, e.g., energy (animal or plant matter). However, a poor quantitative understanding of what natural capital is needed to support biodiversity in ecosystems, while at the same time satisfy human development needs-those associated with human development within socioeconomic systems-undermines our ability to sustainably manage global stocks of natural capital. Here we describe a novel concept and accompanying methodology (relating the adult body mass of terrestrial species to their requirements for land area, water, and energy) to quantify the natural capital needed to support terrestrial species within ecosystems, analogous to how natural capital use by humans is quantified in a socioeconomic context. We apply this methodology to quantify the amount of natural capital needed to support species observed using a specific surveyed site in Scotland. We find that the site can support a larger assemblage of species than those observed using the site; a primary aim of the rewilding project taking place there. This method conceptualises, for the first time, a comprehensive "dual-system" approach: modelling natural capital use in socioeconomic-and eco-systems simultaneously. It can facilitate the management of natural capital at the global scale, and in both the conservation and creation (e.g., rewilding) of biodiversity within managed ecosystems, representing an advancement in determining what socioeconomic trade-offs are needed to achieve contemporary conservation targets alongside ongoing human development.

Factors associated with lower preoperative quality of life in patients with chronic limb-threatening ischemia in the BEST-CLI trial.

OBJECTIVES: There are few contemporary data regarding health-related quality of life (HRQOL) measures in patients with chronic limb-threatening ischemia (CLI). METHODS: The Best Endovascular versus Best Surgical Therapy in Patients with CLI (BEST-CLI) trial is an ongoing, National Institutes of Health-sponsored, multicenter, randomized, controlled trial comparing revascularization strategies in patients with CLI. BEST-CLI baseline HRQOL measures were evaluated for patient-specific variables that were associated with poor HRQOL and then compared with published outcomes. The HRQOL measures Vascular Quality of Life Questionnaire (VascQOL), European Quality of Life 5D (EQ-5D), and the Short Form 12 (SF-12) Index score, physical component score (PCS) and mental component score (MCS) were aggregated from preoperative questionnaires completed by trial patients at baseline visits. Multivariable linear regression models were fit to determine which baseline characteristics were associated with poor HRQOL. RESULTS: We randomized 1830 patients into BEST-CLI. The majority (94.9%, 95.8%, and 95.8%) completed the VascQOL, EQ-5D, and SF-12 instruments at baseline, respectively. In the VascQOL, female sex, smoking history, opioid use, and nonindependent ambulation predicted lower HRQOL scores. Overall, VascuQOL scores were similar to those of participants in the Bypass versus Angioplasty in Severe Ischemia of the Leg (mean, 3.07 ± 1.2 vs mean, 2.9 ± 1.1; P = .07). In EQ-5D, nonindependent ambulation predicted lower HRQOL scores. In the SF-12, female sex, opioid use, nonindependent ambulation, and a history of smoking predicted lower HRQOL scores. The mean SF-12 PCS for all patients in the study was 33.0 ± 8.5 and for the MCS was 46.4 ± 12.0), significantly lower than the national SF-12 scores for US population ages more than 60 years, which is a PCS of 46.5 ± 11.4 and an MCS of 52.9 ± 8.7. CONCLUSIONS: Patients with CLI entering the BEST-CLI trial have very low HRQOL scores, comparable with patients suffering from other chronic conditions characterized by physical limitations and chronic pain. A history of smoking, impaired ambulation, opioid use, and female sex predicted lower HRQOL in patients with CLI, using multiple HRQOL measurement tools.

Design and Implementation of a Nutrition and Breastfeeding Education Program for Black Expecting Mothers and Fathers.

OBJECTIVE: To describe the intervention and research methods of Project Dads in Nutrition Education, an intervention that adds nutrition and breastfeeding education to the existing Healthy Start program in Georgia for Black expecting mothers and fathers to improve nutrition literacy, health outcomes, and breastfeeding rates. DESIGN: This 2-year community-based participatory research study employs a cluster randomization factorial design. SETTING: Six Healthy Start program sites (3 intervention and 3 control sites) in Georgia counties with high infant and maternal mortality rates. PARTICIPANTS: Approximately 480 Black, expecting, Healthy Start program participants (20 couples [mother and father] and 40 single mothers from each site) will be enrolled over the study period. INTERVENTION(S): Project Dads in Nutrition Education will strengthen the capacity of the Georgia Healthy Start program to integrate an evidence-based nutrition education program, breastfeeding education, and father engagement into its routine services. MAIN OUTCOME MEASURE(S): Changes in prepost survey assessment of participants' nutrition literacy and eating behaviors; changes in prepost survey assessment of participants' breastfeeding knowledge, attitudes, intent, initiation, and duration; and health and food diary collected 3 times (ie, at baseline, 3 months, and 6 months after enrollment). ANALYSIS: Process evaluation throughout the study to document implementation. Generalized linear mixed modeling will be used to determine the impact of the intervention.

'Getting involved in research': a co-created, co-delivered and co-analysed course for those with lived experience of health and social care services.

BACKGROUND: 'Getting Involved in Research' was co-created and delivered by a multi-organisational group to provide an accessible introduction to research for those with lived experience of health and social care services. METHOD: The evaluation of participants' perceptions adopted an exploratory mixed method research design and aimed to gather data to provide an in-depth understanding of the participants' experience of 'Getting Involved in Research' through the co-researchers' analysis of qualitative data using Participatory Theme Elicitation (PTE). PTE was used with the qualitative data to promote co-analysis by the course development group; analyses from an independent academic was also used to further validate the method of PTE. RESULTS: Thirty-five participants in total participated in 'Getting Involved in Research'. Age ranges varied from 19 to 73 years old. Participants were predominately female (n = 24), five males participated (n = 5) and there was one participant who identified as non-binary (n = 1). Six core themes were identified using the PTE approach: (1) A Meaningful Participatory Approach (2) Increasing the Confidence of Participants (3) Interactive Online Format (4) An Ambient Learning Environment (5) A Desire for Future Courses (6) A Balance of Course Content and Discussion. Participants in 'Getting Involved in Research' reported that the content of the training was applicable, relevant, fostered awareness of research methods and anticipated that it would support their involvement in research. CONCLUSION: 'Getting Involved in Research' has contributed innovatively to the evidence base for how to engage with and motivate those who have experience of health and social care to become actively involved in research. This study demonstrates that 'Getting Involved in Research' may be helpful to train those with lived experience and their care partners however, further research following up on the application of the course learning would be required to ascertain effectiveness. FUTURE DIRECTIONS: Future research should explore methods to apply research skills in practice to further develop participants' confidence in using the skills gained through 'Getting Involved in Research'.

The aim of this study was to gather information to help us understand the experience of participants' undertaking a research course called 'Getting Involved in Research'. A group of individuals including those with lived experience of health and social care services, academics, community and voluntary sector workers and a representative from the Department of Health in Northern Ireland worked together to develop a course to encourage and support people to engage with research. The 'Getting Involved in Research', course was designed to provide an understandable introduction to research for those people with lived experience of health and social care. We did this because research in health and social care sector should involve the patients and public who it is intended to help. The evaluation of the course had two distinct phases; we asked course participants to complete a survey before and after the course (pre- and post-course survey) and also asked them to complete a journal reflecting on their experiences after each lecture. This paper gives an overview of the profile of course participants and their responses to the survey questions. The survey answers were analysed using an approach to analysing information which encourages involvement from people with a range of experience of research methods, (known as Participatory Theme Elicitation). Thirty-five participants in total participated in 'Getting Involved in Research'. Age ranges varied from 19 to 73 years old. Participants were predominately female (n = 24), five males participated (n = 5) and there was one participant who identified as non-binary (n = 1). Participants in 'Getting Involved in Research' reported that the content of the course was relevant, encouraged awareness of research methods and encourage their future involvement in research.

The remote diet intervention to reduce Long COVID symptoms trial (ReDIRECT): protocol for a randomised controlled trial to determine the effectiveness and cost-effectiveness of a remotely delivered supported weight management programme for people with Long COVID and excess weight, with personalised improvement goals.

Objectves: The Remote Diet Intervention to Reduce Long COVID Symptoms Trial (ReDIRECT) evaluates whether the digitally delivered, evidence-based, cost-effective Counterweight-Plus weight management programme improves symptoms of Long COVID in people with overweight/obesity. Methods: Baseline randomised, non-blinded design with 240 participants allocated in a 1:1 ratio either to continue usual care or to add the remotely delivered Counterweight-Plus weight management programme, which includes a Counterweight dietitian supported delivery of 12 weeks total diet replacement, food reintroduction, and long-term weight loss maintenance. Randomisation is achieved by accessing a web-based randomisation system incorporated into the study web portal developed by a registered Clinical Trials Unit. We are using an innovative approach to outcome personalisation, with each participant selecting their most dominant Long COVID symptom as their primary outcome assessed at six months. Participants in the control arm enter the weight management programme after six months. We are recruiting participants from social media and existing networks (e.g., Long COVID Scotland groups), through newspaper advertisements and from primary care. Main inclusion criteria: people with Long COVID symptoms persisting > three months, aged 18 years or above, body mass index (BMI) above 27kg/m 2 (>25kg/m 2 for South Asians). The trial includes a process evaluation (involving qualitative interviews with participants and analysis of data on dose, fidelity and reach of the intervention) and economic evaluation (within-trial and long-term cost-utility analyses). Anticipated results: The recruitment for this study started in December 2021 and ended in July 2022. Project results are not yet available and will be shared via peer-reviewed publication once the six-months outcomes have been analysed. Trial registration: Current Controlled Trials ISRCTN12595520.

While most people infected with COVID-19 recover within a short amount of time, some people continue to have symptoms for 12 weeks or longer. This condition is known as Long COVID. Roughly two-thirds of people with Long COVID are overweight, a proportion similar to that found in the general population. Being overweight may worsen symptoms such as fatigue, breathlessness and pains. Weight management programmes in adults with overweight/obesity can reduce such symptoms, however we do not know how effective intentional weight loss is to reduce symptoms for people with Long COVID. The aim of this project is to test a well-established weight management programme, delivered and supported remotely, in people with Long COVID. The trial is conducted with 240 people with Long COVID, identified through their GP, patient groups, social media, or newspaper advertisements. A total of 120 individuals will receive the personalised, professionally supported weight management programme (treatment group), and 120 participants are allocated to usual care (control group). The one-year long weight management programme involves 12 weeks of total diet replacement (TDR) using soups and shakes, followed by food reintroduction and weight maintenance. Food based alternatives are available to those who are unable, or prefer not to, follow the TDR approach. The two groups will be compared for Long COVID symptoms, weight loss, quality of life and value for money after six months. After six months, the weight management programme will also be provided for the control group. Experiences while on the programme will be documented for 12 months for all participants. People with Long COVID have been involved extensively in developing this project. Their priorities are to reduce symptoms like fatigue, breathlessness and pain. They are keen to explore if effective weight management would help their symptoms and overall functioning, especially a programme that can be followed remotely from home. A group of patients and other stakeholders has been set up to provide advice throughout the project.

Daily testing for contacts of individuals with SARS-CoV-2 infection and attendance and SARS-CoV-2 transmission in English secondary schools and colleges: an open-label, cluster-randomised trial.

BACKGROUND: School-based COVID-19 contacts in England have been asked to self-isolate at home, missing key educational opportunities. We trialled daily testing of contacts as an alternative to assess whether this resulted in similar control of transmission, while allowing more school attendance. METHODS: We did an open-label, cluster-randomised, controlled trial in secondary schools and further education colleges in England. Schools were randomly assigned (1:1) to self-isolation of school-based COVID-19 contacts for 10 days (control) or to voluntary daily lateral flow device (LFD) testing for 7 days with LFD-negative contacts remaining at school (intervention). Randomisation was stratified according to school type and size, presence of a sixth form, presence of residential students, and proportion of students eligible for free school meals. Group assignment was not masked during procedures or analysis. Coprimary outcomes in all students and staff were COVID-19-related school absence and symptomatic PCR-confirmed COVID-19, adjusted for community case rates, to estimate within-school transmission (non-inferiority margin <50% relative increase). Analyses were done on an intention-to-treat basis using quasi-Poisson regression, also estimating complier average causal effects (CACE). This trial is registered with the ISRCTN registry, ISRCTN18100261. FINDINGS: Between March 18 and May 4, 2021, 204 schools were taken through the consent process, during which three decided not to participate further. 201 schools were randomly assigned (control group n=99, intervention group n=102) in the 10-week study (April 19-May 10, 2021), which continued until the pre-appointed stop date (June 27, 2021). 76 control group schools and 86 intervention group schools actively participated; additional national data allowed most non-participating schools to be included in analysis of coprimary outcomes. 2432 (42·4%) of 5763 intervention group contacts participated in daily contact testing. There were 657 symptomatic PCR-confirmed infections during 7 782 537 days-at-risk (59·1 per 100 000 per week) in the control group and 740 during 8 379 749 days-at-risk (61·8 per 100 000 per week) in the intervention group (intention-to-treat adjusted incidence rate ratio [aIRR] 0·96 [95% CI 0·75-1·22]; p=0·72; CACE aIRR 0·86 [0·55-1·34]). Among students and staff, there were 59 422 (1·62%) COVID-19-related absences during 3 659 017 person-school-days in the control group and 51 541 (1·34%) during 3 845 208 person-school-days in the intervention group (intention-to-treat aIRR 0·80 [95% CI 0·54-1·19]; p=0·27; CACE aIRR 0·61 [0·30-1·23]). INTERPRETATION: Daily contact testing of school-based contacts was non-inferior to self-isolation for control of COVID-19 transmission, with similar rates of symptomatic infections among students and staff with both approaches. Infection rates in school-based contacts were low, with very few school contacts testing positive. Daily contact testing should be considered for implementation as a safe alternative to home isolation following school-based exposures. FUNDING: UK Government Department of Health and Social Care.

Twistorial Foundation for the Classical Double Copy.

The classical double copy relates exact solutions of gauge, gravity, and other theories. Although widely studied, its origins and domain of applicability have remained mysterious. In this Letter, I show that a particular incarnation-the Weyl double copy-can be derived using well-established ideas from twistor theory. As well as explaining where the Weyl double copy comes from, the twistor formalism also shows that it is more general than previously thought.

Religious affiliation and COVID-19-related mortality: a retrospective cohort study of prelockdown and postlockdown risks in England and Wales.

BACKGROUND: COVID-19 mortality risk is associated with demographic and behavioural factors; furthermore, religious gatherings have been linked with the spread of COVID-19. We sought to understand the variation in risk of COVID-19-related death across religious groups in England and Wales both before and after the first national lockdown. METHODS: We conducted a retrospective cohort study of usual residents in England and Wales enumerated at the 2011 Census (n=47 873 294, estimated response rate 94%) for risk of death involving COVID-19 using linked death certificates. Cox regression models were estimated to compare risks between religious groups. Time-dependent coefficients were added to the model allowing HRs before and after lockdown period to be estimated separately. RESULTS: Compared with Christians, all religious groups had an elevated risk of death involving COVID-19; the largest age-adjusted HRs were for Muslim and Jewish males at 2.5 (95% CI 2.3 to 2.7) and 2.1 (95% CI 1.9 to 2.5), respectively. The corresponding HRs for Muslim and Jewish females were 1.9 (95% CI 1.7 to 2.1) and 1.5 (95% CI 1.7 to 2.1), respectively. The difference in risk between groups contracted after lockdown. Those who affiliated with no religion had the lowest risk of COVID-19-related death before and after lockdown. CONCLUSION: The majority of the variation in COVID-19 mortality risk was explained by controlling for sociodemographic and geographic determinants; however, those of Jewish affiliation remained at a higher risk of death compared with all other groups. Lockdown measures were associated with reduced differences in COVID-19 mortality rates between religious groups; further research is required to understand the causal mechanisms.

Roux-en-Y gastric bypass and gastric sleeve surgery result in long term bone loss.

OBJECTIVES: Little is known about the long-term skeletal impact of bariatric procedures, particularly the increasingly commonly performed gastric sleeve surgery (GS). We examined bone density (BMD) change following three types of bariatric surgery Roux-en-Y gastric bypass (RYGB), GS and laparoscopic adjustable gastric banding (LAGB), compared with diet, over 36 months. METHODS: Non-randomized, prospective study of participants with severe obesity (n = 52), undergoing weight-loss interventions: RYGB (n = 7), GS (n = 21), LAGB (n = 11) and diet (n = 13). Measurements of calciotropic indices, gut hormones (fasting and post prandial) peptide YY (PYY), glucagon-like peptide 1 (GLP1) and adiponectin together with dual-X-ray absorptiometry and quantitative computed tomography scans were performed thorough the study. RESULTS: All groups lost weight during the first 12 months. Despite weight stability from 12 to 36 months and supplementation of calcium and vitamin D, there was progressive bone loss at the total hip (TH) over 36 months in RYGB -14% (95% CI: -12, -17) and GS -9% (95% CI: -7, -10). In RYGB forearm BMD also declined over 36 months -9% (95% CI: -6, -12) and LS BMD declined over the first 12 months -7% (95% CI: -3, -12). RYGB and GS groups experienced significantly greater bone loss until 36 months than LAGB and diet groups, which experienced no significant BMD loss. These bone losses remained significant after adjustment for weight loss and age. RYGB and GS procedures resulted in elevated postprandial PYY, adiponectin and bone turnover markers up to 36 months without such changes among LAGB and diet participants. CONCLUSIONS: RYGB and GS but not LAGB resulted in ongoing TH bone loss for three postoperative years. For RYGB, bone loss was also observed at LS and non-weight-bearing forearms. These BMD changes were independent of weight and age differences. We, therefore, recommend close monitoring of bone health following RYGB and GS surgeries.
