Objective: To evaluate total, insulin-mediated, and non-insulin-mediated glucose disposal (TGD, IMGD, and NIMGD) after ingesting glucose in people with obesity and different glycemic status., Research Design and Methods: We developed and validated a new glucose tracer model in conjunction with an oral glucose tolerance test to determine IMGD, NIMGD, and TGD (sum of IMGD and NIMGD) after glucose ingestion in four groups of people: 1) lean with normal glucose tolerance (NGT), 2) obese with insulin resistance and NGT due to hyperinsulinemia (Ob-NGT group), 3) obese with insulin resistance and impaired glucose tolerance (IGT) due to inadequate hyperinsulinemia (Ob-IGT group), and 4) obese with insulin resistance and type 2 diabetes due to marked insulin insufficiency (Ob-T2D group). In addition, we evaluated the effect of intensive lifestyle therapy (ILT) that caused ∼15% weight loss on IMGD and NIMGD in people with obesity and type 2 diabetes (T2D)., Results: IMGD progressively decreased and NIMGD progressively increased from lean to Ob-NGT to Ob-IGT to Ob-T2D. IMGD accounted for about 70%, 65%, 50%, and 20% of TGD, and NIMGD accounted for ∼40%, 35%, 50%, and 80% of TGD in lean, Ob-NGT, Ob-IGT and Ob-T2D, respectively. Although NIMGD was approximately twofold and approximately threefold higher in Ob-IGT and Ob-T2D compared with Ob-NGT, NIMGD only partially compensated for markedly impaired IMGD in the Ob-IGT and Ob-T2D. ILT in people with obesity and T2D increased IMGD and decreased NIMGD., Conclusions: NIMGD is a major mechanism of postprandial TGD in people with insulin resistance and inadequate insulin secretion., (© 2024 by the American Diabetes Association.)

Background: There is a critical global shortage of nurses in mental health, with workforce attrition due in large part to workplace stressors. Proactive strengths-based interventions to strengthen nurses' capacity to manage stress and improve mental health, wellbeing and resilience may also support workforce retention., Objective: To determine the effects of a resilience-building programme on mental health nurses' coping self-efficacy (primary outcome), and psychological distress, wellbeing, resilience, posttraumatic growth, emotional intelligence behaviours, workplace belonging, and turnover intention (secondary outcomes)., Design: Partially clustered randomised controlled trial., Setting: Large tertiary metropolitan mental health service in Australia., Participants: A total of 144 registered and enrolled nurses working clinically ≥0.6 full-time equivalent (73/intervention, 71/control), with 122 completing 3-month follow-up., Methods: The Promoting Resilience in Nurses programme is an evidence-based workplace intervention delivered by trained facilitators across two workshops. Surveys were administered online upon registration and prior to randomisation (Time 1) into Intervention or Control (no intervention) arms, and immediately after the final workshop (Time 2), and at three months follow-up (Time 3). Linear mixed models for outcome measures were fitted to Time 2 and 3 responses., Results: There were seven intervention groups, with seven to 13 participants per group. Coping self-efficacy improved at Time 2 (estimated intervention effect 21.2 units, 95 % Confidence Intervals: 13.3 to 29.0) and Time 3 (12.1 units, 4.7 to 19.6), as well as wellbeing (Time 2: 9.2 units, 5.0 to 13.4), resilience (Time 2: 0.24 units, 0.01 to 0.46) and posttraumatic growth (Time 2: 16.1 units, 7.0 to 25.3). Psychological distress reduced (Time 2: -3.7 units, -6.2 to -1.31). All were sustained at three months. Emotional intelligence behaviours were improved (Time 2: 3.5 units, 0.6 to 6.5) but not sustained. Workplace belonging improved at Time 3 (0.34 units, 0.02 to 0.65) only. No statistically significant effects for turnover intention., Conclusions: Despite major contextual challenges, the Promoting Resilience in Nurses programme achieved the aims of promoting nurses' efficacy to cope with stress and regulate their emotions and improving mental health and wellbeing. The findings support the programme as a feasible and successful intervention for nurses across other settings and contexts., Trial Registration: Australian New Zealand Clinical Trials Registry (ACTRN12620001052921).

Synchronous positive affect (SPA) is a key element of parent-child interaction quality which is related to favorable developmental outcomes. Children with autism spectrum disorder (ASD) and their parents tend to show less SPA compared to other populations. The current study explored changes in SPA made by parents and their children with ASD following the Preschool-Based Early Start Denver Model (PB-ESDM) intervention. Thirty children receiving PB-ESDM and 23 receiving treatment-as-usual (TAU) were assessed pre- and post- intervention using microanalysis of video-recorded parent-child interactions, in which SPA was quantified. Results showed a significant increase in SPA among children receiving PB-ESDM who had lower pre-treatment adaptive functioning. These findings suggest that SPA may serve as a sensitive treatment outcome measure for children with poorer adaptive functioning, who often struggle to show significant changes on standardized measures. The study's modest sample and non-randomized design are noted as limitations., (© 2022. The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.)

Dominant theoretical accounts of interpersonal synchrony, the temporal coordination of biobehavioral processes between several individuals, have employed a linear approach, generally considering synchrony as a positive state, and utilizing aggregate scores. However, synchrony is known to take on a dynamical form with continuous shifts in its timeline. Acting as one continuously, is not always the optimal state, due to an intrinsic tension between individualistic and synergistic forms of action that exist in many social situations. We propose an alternative theory of flexible multimodal synchrony which highlights context as a key component that defines "pulls" toward synchrony and "pulls" toward segregation inherent to the social situation. Traitlike individual differences and relationship variables then sensitize individuals to these contextual "pulls." In this manner, context, individual differences, and relationship variables provide the backdrop to the emergence of flexible and dynamical synchrony patterns, which we consider adaptive, in several modalities-behavioral, physiological, and neural. We point to three consequences of synchrony patterns: social-, task, and self-oriented. We discuss multimodal associations that arise in different contexts considering the theory and delineate hypotheses that emanate from the theory. We then provide two empirical proofs-of-concept: First, we show how individual differences modulate the effect of context on synchrony's outcomes in a novel dyadic motor game. Second, we reanalyze previously reported data, to show how a "flexibility" approach to synchrony data analysis improves predictive ability when testing for synchrony's effects on social cohesion. We provide ways to standardize the characterization of context and guidelines for future synchrony research. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Dysfunctional adipose tissue is believed to promote the development of hepatic steatosis and systemic insulin resistance, but many of the mechanisms involved are still unclear. Lipin 1 catalyzes the conversion of phosphatidic acid to diacylglycerol (DAG), the penultimate step of triglyceride synthesis, which is essential for lipid storage. Herein we found that adipose tissue LPIN1 expression is decreased in people with obesity compared to lean subjects, and low LPIN1 expression correlated with multi-tissue insulin resistance and increased rates of hepatic de novo lipogenesis. Comprehensive metabolic and multi-omic phenotyping demonstrated that adipocyte-specific Lpin1-/- mice had a metabolically-unhealthy phenotype, including liver and skeletal muscle insulin resistance, hepatic steatosis, increased hepatic de novo lipogenesis, and transcriptomic signatures of metabolically associated steatohepatitis that was exacerbated by high-fat diets. We conclude that adipocyte lipin 1-mediated lipid storage is vital for preserving adipose tissue and systemic metabolic health, and its loss predisposes mice to metabolically associated steatohepatitis.

The current article introduces lagged multidimensional recurrence quantification analysis. The method is an extension of multidimensional recurrence quantification analysis and allows to quantify the joint dynamics of multivariate time series and to investigate leader-follower relationships in behavioral and physiological data. Moreover, the method enables the quantification of the joint dynamics of a group, when such leader-follower relationships are taken into account. We first provide a formal presentation of the method, and then apply it to synthetic data, as well as data sets from joint action research, investigating the shared dynamics of facial expression and beats-per-minute recordings within different groups. A wrapper function is included, for applying the method together with the "crqa" package in R. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Nursing education holds a history framed in white supremacy and whiteness. Efforts to employ antiracist strategies have been hindered, largely due to an inability for faculty to acknowledge and hold accountability for racialized harms that occur within nursing educational structures. A nurse-midwifery program in the Pacific Northwest United States uncovered harm that impacted students and identified a need to respond and hold accountability. Guided by the framework of Transformative Justice, a truth and reconciliation process was implemented as a first step to better address racism within nursing and nurse-midwifery education. This paper describes the process to support other institutions in their work to address harms within nursing education., (© 2024 John Wiley & Sons Ltd.)

Caregiving plays a critical role in children's cognitive, emotional, and psychological well-being. In the current longitudinal study, we investigated the enduring effects of early maternal behavior on processes of interbrain synchrony in adolescence. Mother-infant naturalistic interactions were filmed when infants were 3-4 months old and interactions were coded for maternal sensitivity and intrusiveness with the Coding Interactive Behavior Manual. In early adolescence (Mean = 12.30, SD = 1.25), mother-adolescent interbrain synchrony was measured using hyperscanning EEG during a naturalistic interaction of positive valence. Guided by previous hyperscanning studies, we focused on interbrain connections within the right frontotemporal interbrain network. Results indicate that maternal sensitivity in early infancy was longitudinally associated with neural synchrony in the right interbrain frontotemporal network. Post-hoc comparisons highlighted enhancement of mother-adolescent frontal-frontal connectivity, a connection that has been implicated in parent-child social communication. In contrast, maternal intrusiveness in infancy was linked with attenuation of interbrain synchrony in the right interbrain frontotemporal network. Sensitivity and intrusiveness are key maternal social orientations that have shown to be individually stable in the mother-child relationship from infancy to adulthood and foreshadow children's positive and negative social-emotional outcomes, respectively. Our findings are the first to demonstrate that these two maternal orientations play a role in enhancing or attenuating the child's interbrain frontotemporal network, which sustains social communication and affiliation. Results suggest that the reported long-term impact of maternal sensitivity and intrusiveness may relate, in part, to its effects on tuning the child's brain to sociality., (© 2024. The Author(s).)

Due to intensification processes that have had negative impacts on environmental externalities, pastoral farmers, worldwide, are facing increasing scrutiny and pressure from consumers, governments, and the public to reduce the environmental footprint of their operations. Developing tools and systems that farmers can use to maintain profitability and productivity while decreasing the negative externalities of their operations is important for the vitality of rural sectors. Capitalising on individual animal variation has been promoted as an opportunity to increase animal productivity and enhance welfare while decreasing the negative environmental impacts of pastoral farming. Of particular interest are behaviours that are associated with foraging, as these are the primary drivers of variation in animal performance in pastoral farming. Developing a methodology that can identify consistent foraging behavioural variations across individuals is a critical step in making this a practical solution for farmers and herders. As with all behavioural research, the fundamental challenge is selecting the appropriate behaviours to measure. Understanding the contextual drivers of behavioural expression is a major development in this process. Herd management and composition, environmental variables and many more contexts alter the expression of behaviours, so how do we capture behaviours of interest? We propose the use of a systematic methodology to capture behaviours of significance from large groups of foraging ruminants using wearable technology, namely Global Positioning System and accelerometers. This contrasts with traditional reductionist methodologies used in behaviour research and has the benefit of providing large objective datasets from undisturbed animals. Statistical analysis of the data will inform behaviours of interest that are clustered together to inform a three-factor foraging behaviour syndrome model adapted from the animal five-factor model (activity, aggression, boldness, exploration, sociability) of personality. Syndromes, unlike personalities, include correlated suites of behaviours that are expressed across spatial and temporal contexts. By capturing foraging behaviour syndromes, selection can be used to match appropriate syndromes to different pastoral farming landscapes, thereby potentially improving the system's productivity while reducing their negative environmental impact., (Copyright © 2024 The Author(s).

Background: Diagnostic imaging using CT enterography, magnetic resonance enterography, and intestinal ultrasound are important tools in evaluating stricturing Crohn's disease. Definitions of strictures have been developed for CT enterography and magnetic resonance enterography. However, expert recommendations for definitions and treatment response of strictures on intestinal ultrasound are not available. The aim of this study was to standardise definitions, diagnosis, and treatment response criteria in small bowel stricturing Crohn's disease on intestinal ultrasound., Methods: Using modified RAND-University of California Los Angeles Appropriateness Method, a diverse expert panel of 13 gastroenterologists, seven radiologists, and two patient representatives was assembled. A total of 466 statements on definitions and response to therapy of stricturing Crohn's disease on intestinal ultrasound were generated from a systematic review and from expert opinion, with subsequent rating for appropriateness. Two rounds of voting with an interposed survey result discussion were performed. Statements were classified as inappropriate, uncertain, or appropriate based on the median panel rating and degree of disagreement. Appropriateness was rated using a nine-point Likert scale (1 being inappropriate, 9 being highly appropriate)., Findings: A naive or anastomotic small bowel Crohn's disease stricture on intestinal ultrasound is defined by the combination of bowel wall thickening, luminal narrowing, and pre-stenotic dilation. Bowel wall thickness is defined as being more than 3 mm. Luminal narrowing is defined as either a luminal diameter reduction of more than 50% in the narrowest area and relative to a normal adjacent bowel loop, or a luminal diameter of less than 1 cm. Pre-stenotic dilation is defined as more than 2·5 cm or an increase in bowel diameter relative to a normal adjacent bowel loop. Definitions for grading hyperaemia, inflammatory fat, wall stratification, intestinal ultrasound machine technical parameters, and image acquisition were also devised. Treatment response of strictures was defined as reduction in stricture length, bowel wall thickening, luminal narrowing, pre-stenotic dilation, and motility abnormalities., Interpretation: To our knowledge, this is the first intestinal ultrasound appropriateness rating exercise conducted for defining, diagnosing, and measuring response to therapy in small bowel stricturing Crohn's disease and informs future clinical use and intestinal ultrasound index development for clinical trials., Funding: Leona M and Harry B Helmsley Charitable Trust., Competing Interests: Declaration of interests CL has received speaker fees from AbbVie, Celltrion, Janssen, and Fresenius Kabi, and advisory board fees from AbbVie, Janssen, Lilly, Pfizer, Takeda, Fresenius Kabi, Pendopharm, and Ferring.

Background: Late morbidity after childhood cancer may be mitigated by healthy lifestyle behaviors. We piloted a game-based, parent-child digital intervention to increase activity in sedentary survivors., Methods: Survivors aged 10-16 treated with cardiotoxic therapy and not meeting US physical activity guidelines were enrolled in a single-arm study with a parent. Following a 14-day run-in, participants chose a prespecified step goal and wore an accelerometer daily for 24 weeks (12-week game-based intervention; 12-week follow-up). Participants completed the Acceptability of Intervention Measure (AIM) at 24 weeks; a subset of dyads completed qualitative interviews., Results: Among 129 eligible survivors, 27 enrolled (20.9% participation rate) with a parent. Four dyads were removed during the 14-day run-in period due to noncompliance. Among the 23 dyads who continued to the study, the tracker was worn for 95% of days during the 12-week intervention (95% confidence interval [CI]: 94-96) and 81% during the 12-week follow-up (95% CI: 79-82). Overall, the prespecified step goal was met for 64% (95% CI: 63-66) of days during the intervention and 37% (95% CI: 35-38) during the follow-up. At the end of study, 17/23 dyads responded to AIM; 82% of survivors and 94% of parents reported the intervention as acceptable. During qualitative interviews (n = 5), dyads noted that they liked the accountability of the "buddy system," but would have liked more personalized goal-setting., Conclusions: Despite high ratings of acceptability among participants, difficulties with sustained adherence and retention were encountered in this parent-child gamification intervention. Alternate, tailored designs should be considered in the future., (© 2024 Wiley Periodicals LLC.)

Muscle sn-1,2-diacylglycerol (DAG) and C18:0 ceramide accumulation in sarcolemmal and mitochondrial compartments have been proposed to regulate muscle insulin sensitivity. Here, we evaluated whether weight loss-induced improvements in insulin sensitivity were associated with changes in muscle sn-1,2-DAG and ceramide content in people with obesity and type 2 diabetes. We measured skeletal muscle insulin sensitivity, assessed by using the hyperinsulinemic-euglycemic clamp procedure in conjunction with stable isotopically labeled glucose tracer infusion, and skeletal muscle sn-1,2-DAG and ceramide contents by using liquid chromatography-tandem mass spectrometry after subcellular fractionation and DAG isomer separation in 14 adults with obesity and type 2 diabetes before and after marked (18.6 ± 2.1%) weight loss. Whole-body insulin sensitivity doubled after weight loss. Sarcolemmal sn-1,2-DAG and C18:0 ceramide contents after weight loss were not different from values before weight loss. In contrast, mitochondrial-endoplasmic reticulum (ER) C18:0 ceramide content decreased by ∼20% after weight loss (from 2.16 ± 0.08 to 1.71 ± 0.13 nmol/g, P < 0.005). These results suggest a decrease in muscle mitochondrial-ER C18:0 ceramide content could contribute to the beneficial effect of weight loss on skeletal muscle insulin sensitivity., (© 2024 by the American Diabetes Association.)

The Difficulties in Emotion Regulation Scale (DERS) is frequently used to assess emotion regulation (ER) capabilities. Originally a multidimensional scale, many utilize its total score, without clear recommendations. We aimed to explore the DERS's structure, dimensionality, and utility and provide clinicians and researchers with clear guidelines. Self-report data on ER, personality, psychopathology, and life satisfaction were collected from 502 adults. Seventy also participated in a lab study evaluating group interactions, which included additional self-report and physiological monitoring. Findings suggested favoring the correlated-traits and bifactor models, the latter excelling in direct comparisons. The total score was found reliable and valid, explaining 53.3% of the variance, with a distinct emotional awareness subfactor, suggesting a non-pure unidimensional solution. A cutoff score of 95 identified significant ER difficulties, linked to psychopathology. We thus recommend using the DERS's total score and 95 as its cutoff, while calling for further validation in diverse and clinical samples., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objectives: Early opioid initiation is recommended for advanced cancer pain, however the timing of opioid commencement in relation to diagnosis has not been described, and the role of palliative care prescribers is unclear. This study aims to determine the timing of opioid initiation by prescriber and cancer type in relation to key timepoints in the cancer illness course (diagnosis, palliative care referral and death)., Methods: This retrospective cohort study included patients at a quaternary cancer centre with incurable advanced cancer of five different subtype groups. Demographics, clinical characteristics, health service use and details of first slow and immediate release opioid prescription are reported., Results: Among 200 patients, median time to first immediate release opioid prescription was 23 days (IQR 1-82) and to slow release opioid prescription was 47 days (IQR 14-155). Most patients (95%, (n=190) were referred to palliative care (median time to referral 54 days (IQR 18-190)). Non-palliative care prescribers initiated slow release opioids for half the cohort (49%, n=97) prior to referral. Patients with pancreatic cancer had the shortest time to slow/immediate release opioid prescription (median 10 days (IQR 0-39) and 26 days (IQR 1-43) respectively) and shortest survival (median 136 days (IQR 82-214))., Conclusions: Median time to opioid commencement was approximately 3 weeks after diagnosis. Despite early palliative care involvement, opioid initiation by non-palliative care clinicians was common and remains important. Timely palliative care referral for those with pancreatic cancer may include consideration of earlier complex pain presentations and shorter prognosis., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Introduction: Successful treatment of TB requires high levels of adherence to treatment. This has been found to be below optimal with directly observed therapy (DOT), and digital adherence technologies (DATs) offer a promising approach to non-adherence to medication and improving treatment outcomes. This study explores the perception, acceptability, and challenges of DATs among healthcare workers (HCWs)., Methods: The study was conducted in eight states in Nigeria among Health Care workers involved in treating patients with TB. This was a descriptive cross-sectional study using an open questionnaire and analysed using IBM SPSS v25., Results: Twenty-three HCWs (95.8%) agreed that DATs helped them provide better support and counselling to their patients. All of them would recommend DATs to their patients and found it easy to explain them. Eleven (45.8%) of them were not able to use DATs on a few occasions; their reasons were poor network ( n = 9, 37.5%) and ( n = 1, 4.2%) power failure., Conclusion: DATs help HCWs provide better support and care regarding real-time tracking of their patients' adherence to treatment and possibly reduction of attrition. This implies that DATs are a suitable alternative to DOT to help HCWs provide the best care and support to their patients towards achieving the End TB targets., (© 2024 The Authors.)

Introduction: Poor adherence to TB treatment poses a significant public health threat to TB control programmes. The sustainability of directly observed treatment has been questioned because of its non-patient-centred approach and resource-intensive nature, and Digital Adherence Technologies (DATs) provide a suitable alternative. This study assessed the feasibility and acceptability of DATs among patients with TB., Methods: This descriptive study was conducted in eight states in Nigeria among all patients with drug-susceptible TB., Result: A total of 230 patients (89.1%) own a phone that no one else uses, and 18 (7.0%) use a family phone. A higher proportion of 189 (73.3%) have airtime credit and 119 (46.1%) have internet credit on their phone. In addition, 216 (83.7%) stated that the reminders they received on their phone helped them remember to take their medicine. Only 11 (4.3%) patients missed a dose of the TB medicine. Equally, 11 (4.3%) patients had taken their TB medicine without using DAT. Of these, 7 (63.3%) did not use DATs because they forgot to text medication labels, and 3 (27.6%) did so because of poor network. Only four (1.6%) purchased additional items to support the use of DATs., Conclusion: DATs are acceptable in a wide variety of settings, even with reported challenges. Implementation efforts should ensure access, address technical challenges, and minimise additional cost to patients., Competing Interests: Conflicts of interest: none declared., (© 2024 The Authors.)

Background: Autistic people are a high-risk group for self-harm and suicide. There are no evidence-based suicide prevention interventions developed specifically for autistic people. We undertook a pilot feasibility randomised controlled trial of autism adapted safety plans (AASP) to reduce self-harm and suicide for autistic people., Methods: This study took place in the United Kingdom and followed a randomised, two-arm, controlled design. Autistic adults (n = 53, mean age = 39, gender = 49% female, 29% not male or female) were recruited via third sector organisations and self-referral between 11.8.21 and 19.10.22. Participants were randomised without stratification to usual care with or without AASP. The AASP was completed by the autistic adults together with someone trained to support them. Research staff who completed follow-up assessments were blind to participant allocation. Primary outcomes were feasibility and acceptability. Participants were assessed at baseline, 1 and 6 months. Primary data were analysed under the intention to treat principle. Study protocol is published. The trial is closed to new participants. This study is registered with the ISRCTN registry, ISRCTN70594445., Findings: 53 participants consented, 49 were randomised to either AASP with usual care (n = 25) or usual care (n = 24). 68% of participants in the AASP arm were satisfied with the AASP and 41% rated it as useable. Feedback on the AASP and research methods were positive with suggested adaptations to some outcome measures. Retention and completion of outcomes measures in both arms was excellent, as was fidelity of delivery of the AASP., Interpretation: Study progression criteria were met, suggesting that the parameters of a future definitive trial of clinical and cost effectiveness of AASP to reduce self-harm and suicide in autistic adults are achievable, with minor recommended adaptions to outcome measures and AASP. Future research should explore the use of AASP in routine clinical practice., Funding: This study is funded by the NIHR [Public Health Research Programme (NIHR129196)]., Competing Interests: SC reports grants from the Economic and Social Research Council (ESRC) Autistica, Chief Scientist Office, the International Society for Autism Research and National Institute for Health Research (NIHR); occasional fees for delivering workshops and invited addresses; occasional fees for acting as an expert witness in coroners’ inquests; and participation in a trial data monitoring and ethics committee.

Background: Uncorrected refractive error is a leading cause of vision impairment which, in most cases, can be managed with the appropriate spectacle correction. In 2021, the World Health Assembly endorsed a global target of a 40-percentage-point increase in effective coverage of refractive error by 2030. To achieve this global target, equitable access to refractive and optical services within community and primary care settings needs to be strengthened. This review will inform the development of technical guidance to support improvements in the testing and correction of refractive error among World Health Organization (WHO) member states., Objectives: To determine the range of approaches for delivery of refractive and optical care services in community and primary care settings, and the methods employed for their evaluation., Search Methods: We searched CENTRAL, MEDLINE, Embase and Global Health databases, grey literature, and annual reports and websites of relevant organizations involved in eye-care delivery from January 2002 to November 2022 to identify approaches for refractive and optical service delivery., Selection Criteria: We included observational and interventional studies, reviews, and reports from relevant organizations related to delivering refractive services and optical services for preschool and school-aged children and adults in community and primary care settings published between January 2002 and November 2022. We searched for studies and reports published within the last 20 years because vision impairment due to uncorrected refractive error has only recently become a public health and eye health priority, therefore we did not expect to find much relevant literature until after 2002., Data Collection and Analysis: Two review authors screened titles, abstracts and full texts, and extracted data. We resolved any discrepancies through discussion. We synthesized data, and presented results as tables, figures, and case studies. This project was led by the World Health Organization (WHO) Vision and Eye Care Programme., Main Results: We identified 175 studies from searches of databases and grey literature, 146 records from company reports, and 81 records from website searches of relevant organizations that matched our inclusion criteria. Delivery approaches for refractive and optical services in community care included school-based, pharmacy, and outreach models, whereas primary care approaches comprised vision centre, health centre, and a combination of vision or health centre and door-to-door delivery. In community care, school-based and outreach approaches were predominant, while in primary care, a vision-centre approach was mainly used. In the WHO African region, the school-based and outreach approaches were mainly reported while, in the Americas, the outreach approach was mostly used. Very few approaches for service delivery were reported in the WHO Eastern Mediterranean region. Prominent gaps exist in the evaluation of the approaches, and few studies attempted to evaluate the approaches for delivery of refractive and optical care services., Authors' Conclusions: We comprehensively describe a range of approaches for delivery of refractive and optical services in community and primary care. Further evaluation of their effectiveness will better inform the application of these service-delivery approaches. The study outcomes will help guide WHO member states in strengthening refractive and optical services at community and primary care levels., Funding: This scoping review was supported by the Vision and Eye care Programme, World Health Organization and ATscale Global Partnership., Registration: The protocol of this scoping review was published in the Open Source Framework., (Copyright © 2024 The Authors.

There is considerable heterogeneity in the cardiometabolic abnormalities associated with obesity. We evaluated multi-organ system metabolic function in 20 adults with metabolically healthy obesity (MHO; normal fasting glucose and triglycerides, oral glucose tolerance, intrahepatic triglyceride content, and whole-body insulin sensitivity), 20 adults with metabolically unhealthy obesity (MUO; prediabetes, hepatic steatosis, and whole-body insulin resistance), and 15 adults who were metabolically healthy lean. Compared with MUO, people with MHO had (1) altered skeletal muscle biology (decreased ceramide content and increased expression of genes involved in BCAA catabolism and mitochondrial structure/function); (2) altered adipose tissue biology (decreased expression of genes involved in inflammation and extracellular matrix remodeling and increased expression of genes involved in lipogenesis); (3) lower 24-h plasma glucose, insulin, non-esterified fatty acids, and triglycerides; (4) higher plasma adiponectin and lower plasma PAI-1 concentrations; and (5) decreased oxidative stress. These findings provide a framework of potential mechanisms responsible for MHO and the metabolic heterogeneity of obesity.

Introduction: To date, studies focusing on the connection between psychological functioning and autonomic nervous system (ANS) activity usually adopted the one-dimensional model of autonomic balance, according to which activation of one branch of the ANS is accompanied by an inhibition of the other. However, the sympathetic and parasympathetic branches also activate independently; thus, co-activation and co-inhibition may occur, which is demonstrated by a two-dimensional model of ANS activity. Here, we apply such models to assess how markers of the autonomic space relate to several critical psychological constructs: emotional contagion (EC), general anxiety, and positive and negative affect (PA and NA). We also examined gender differences in those psychophysiological relations., Methods: In the present study, we analyzed data from 408 healthy students, who underwent a 5-min group baseline period as part of their participation in several experiments and completed self-reported questionnaires. Electrocardiogram (ECG), electrodermal activity (EDA), and respiration were recorded. Respiratory sinus arrhythmia (RSA), pre-ejection period (PEP), as well as cardiac autonomic balance (CAB) and regulation (CAR) and cross-system autonomic balance (CSAB) and regulation (CSAR), were calculated., Results: Notably, two-dimensional models were more suitable for predicting and describing most psychological constructs. Gender differences were found in psychological and physiological aspects as well as in psychophysiological relations. Women's EC scores were negatively correlated with sympathetic activity and positively linked to parasympathetic dominance. Men's PA and NA scores were positively associated with sympathetic activity. PA in men also had a positive link to an overall activation of the ANS, and a negative link to parasympathetic dominance., Discussion: The current results expand our understanding of the psychological aspects of the autonomic space model and psychophysiological associations. Gender differences and strengths and weaknesses of alternative physiological models are discussed., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. The author(s) declared that they were an editorial board member of Frontiers, at the time of submission.

Introduction: Glaucoma is the leading cause of irreversible blindness in the world. The need to diagnose glaucoma early in its natural history before extensive sight loss occurs cannot be overemphasised. However, glaucoma is largely asymptomatic in the early stages of the disease making it complex to diagnose clinically and requires the support of technology. The objective of this scoping review is to determine the nature and extent of the evidence for use of portable devices in the diagnosis of glaucoma., Methods: We will consider studies conducted in all healthcare settings using portable devices for the detection of all type of adult glaucoma. We will also include any systematic reviews or scoping reviews, which relate to this topic. Searches will be conducted in MEDLINE, Embase, CENTRAL on the Cochrane Library and Global Health databases, from their inception to the present. Reference lists from publications identified in the searches will also be reviewed. Two authors will independently screen titles and abstracts, followed by full-text screening to assess studies for inclusion. Any disagreements will be discussed and resolved with a third author. Tables accompanied by narrative descriptions will be employed to discuss results and show how it relates to review questions., Ethics and Dissemination: Ethical approval is not required in this review. Only published and publicly accessible data will be used. We will publish our findings in an open-access, peer-reviewed journal and develop an accessible summary of results and recommendations., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Physiological responses to environmental and social stimuli have been studied broadly in relation to psychological states and processes. This may be especially important regarding autistic individuals, who show disparities in social interactions. However, findings from studies assessing autonomic nervous system (ANS) responses of autistic individuals present contradictions, with reports showing both autonomic disparities and intact autonomic functioning. The current study aimed to review the existing literature and to estimate if there is a difference between autistic individuals and neurotypical (NT) individuals in their autonomic responses to social stimuli. Furthermore, the study examined factors that may moderate this difference, including the type of physiological function measured, the level of participation required, as well as the age and intellectual functioning of the participants. The meta-analysis revealed a small and statistically insignificant overall difference between autistic and NT individuals, albeit with high heterogeneity. A further nested moderator analysis revealed a significant difference between autistic and NT individuals in physiological response that reflects mainly a parasympathetic nervous system (PNS) activity. Another difference was found in physiological response that reflects a combined activity of the sympathetic and parasympathetic systems, but only for experimental tasks that demanded active participation in social interactions. These results suggest a distinctiveness in autonomic regulation of autistic individuals in social situations, and point to the PNS as an important study objective for future investigation., (© 2023 The Authors.

Objective: Psychological distress is prevalent in couples facing breast cancer. Couples often deal with breast cancer as a unit instead of as individuals. Couple's dyadic coping is important for their adjustment to breast cancer; however, little is known about how couple's coping congruence influences their distress. This study examined how common dyadic coping (CDC) and coping congruence impact psychological distress in couples facing breast cancer., Methods: Baseline data were analyzed from 343 women with recently diagnosed early-stage breast cancer and their partners who participated in a randomized clinical trial. Psychological distress was indicated by depressed mood and state anxiety. Common dyadic coping was measured by a self-report scale. Coping congruence was assessed by the absolute difference between a woman's and her partner's CDC scores., Results: Higher CDC scores were associated with lower psychological distress in both women and partners. In the CDC subscales, women who suffered less scored higher on open communication, sharing a positive outlook, and lower on avoidance coping. Partners who suffered less scored higher on open communication, sharing a positive outlook, spending time talking, and lower on avoidance coping. Greater congruence in CDC was associated with lower psychological distress in women and their partners. Congruence in sharing a positive outlook benefited both members of the dyad; congruence in avoidance coping significantly benefited patients; congruence in open communication significantly benefited partners., Conclusions: CDC and its congruence in specific areas have potential benefit to couple's psychological distress when facing breast cancer. Health care providers could consider enhancing couple's CDC and coping congruence to improve their adjustment., (© 2024 John Wiley & Sons Ltd.)

Objective: The objective of this study was to evaluate the relative importance of the basal rate of glucose appearance (Ra) in the circulation and the basal rate of plasma glucose clearance in determining fasting plasma glucose concentration in people with obesity and different fasting glycemic statuses., Methods: The authors evaluated basal glucose kinetics in 33 lean people with normal fasting glucose (<100 mg/dL; Lean < 100 group) and 206 people with obesity and normal fasting glucose (Ob < 100 group, n = 118), impaired fasting glucose (100-125 mg/dL; Ob 100-125 group, n = 66), or fasting glucose diagnostic of diabetes (≥126 mg/dL; Ob ≥ 126 group, n = 22)., Results: Although there was a large (up to three-fold) range in glucose Ra within each group, the ranges in glucose concentration in the Lean < 100, Ob < 100, and Ob 100-125 groups were small because of a close relationship between glucose Ra and clearance rate. However, the glucose clearance rate at any Ra value was lower in the hyperglycemic than the normoglycemic groups. In the Ob ≥ 126 group, plasma glucose concentration was primarily determined by glucose Ra, because glucose clearance was markedly attenuated., Conclusions: Fasting hyperglycemia in people with obesity represents a disruption of the precisely regulated integration of glucose production and clearance rates., (© 2024 The Obesity Society.)

Introduction: Diabetic retinopathy is a leading cause of vision impairment globally. Vision loss from diabetic retinopathy can generally be prevented by early detection and timely treatment. The WHO included a measure of service access for diabetic retinopathy as a core indicator in the Eye Care Indicator Menu launched in 2022: retina screening coverage for people with diabetes . The aim of this review is to provide a comprehensive global and regional summary of the available information on retina screening coverage for people with diabetes., Methods and Analysis: A search will be conducted in five databases without language restrictions for studies from any country reporting retina screening coverage for adults with any type of diabetes at the national or subnational level using data collected since 1 January 2000 until the search date. We will also seek reports and coverage statistics from government websites of all WHO member states. Two investigators will independently screen studies, extract relevant data and assess risk of bias of included studies. The results of the review will be reported using the Preferred Reporting Items for Systematic Review and Meta-Analysis guideline. We will summarise the range of coverage definitions reported across included studies and present the median retina screening coverage in WHO regions and by World Bank country income level. Depending on the availability of data, we will conduct meta-analysis to assess disparities in retina screening coverage for people with diabetes by factors in the PROGRESS framework (Place of residence, Race/ethnicity/culture/language, Occupation, Gender/sex, Religion, Education, Socioeconomic status and Social capital)., Ethics and Dissemination: This review will only include published data thus no ethical approval will be sought. The findings of this review will be published in a peer-reviewed journal and presented at relevant conferences., Protocol Registration Number: OSF registration 17/10/2023: https://osf.io/k5p69., Competing Interests: Competing interests: None declared., (© World Health Organization 2024.

Objective: Couples' joint coping is important in managing the impact of breast cancer. However, measures assessing couples' communication as a way of coping are insufficient. This study aimed to generate a self-report valid and reliable measure of couples' coping with a particular focus on communication., Method: We used baseline data of 343 couple dyads who participated in a randomized clinical trial targeting marital communication. Women were diagnosed with early-stage breast cancer in the past eight months; couples were married or in an intimate relationship for at least six months, could read and write English, and lived within 100 miles of the study center. An expert panel selected items with conceptual fit from the Mutuality and Interpersonal Sensitivity Scale (MIS) that was originally designed to evaluate marital communication about breast cancer., Results: Exploratory and confirmatory factor analyses supported a 12-item measurement model with four factors: Keeping the communication open with each other about breast cancer (4 items), Sharing a positive outlook on breast cancer (2 items), Avoiding discussion of negative thoughts and feelings about breast cancer (3 items), and Spending sufficient time together talking about breast cancer (3 items). Reliability ranged from 0.76 to 0.87 for women and 0.70 to 0.83 for spouses., Conclusion: This new measure has potential application in clinical practice and future research to assess couple's joint coping efforts especially through communication.

Oxytocin (OXT), a nine-amino-acid peptide produced in the hypothalamus and released by the posterior pituitary, has well-known actions in parturition, lactation and social behaviour 1 , and has become an intriguing therapeutic target for conditions such as autism and schizophrenia 2 . Exogenous OXT has also been shown to have effects on body weight, lipid levels and glucose homeostasis 1,3 , suggesting that it may also have therapeutic potential for metabolic disease 1,4 . It is unclear, however, whether endogenous OXT participates in metabolic homeostasis. Here we show that OXT is a critical regulator of adipose tissue lipolysis in both mice and humans. In addition, OXT serves to facilitate the ability of β-adrenergic agonists to fully promote lipolysis. Most surprisingly, the relevant source of OXT in these metabolic actions is a previously unidentified subpopulation of tyrosine hydroxylase-positive sympathetic neurons. Our data reveal that OXT from the peripheral nervous system is an endogenous regulator of adipose and systemic metabolism., (© 2023.

Background: The advancement of universal health coverage (UHC) is largely based on identifying and addressing barriers to accessing community health services. Traditional qualitative research approaches provide excellent insights but have unfeasibly high resource requirements for most care providers., Aim: To identify, categorise, and evaluate methods that have been used to identify barriers to and/or solutions for improving access to community-based health services, grounded in engagement with affected communities, excluding approaches that take >14 days., Design & Setting: This was a scoping review., Method: Following Joanna Briggs Institute (JBI) guidelines, a search was undertaken using the Cochrane Library, Ovid MEDLINE, Ovid Embase, Ovid Global Health, and Google Scholar. An information specialist designed the search, and dual independent review and data charting were used., Results: In total, 44 studies were included from 30 countries, reporting on 18 different clinical services. Thirty studies used self-described 'rapid' approaches; however, the majority of these did not justify what they meant by this term. Nearly half of the studies used mixed- or multi-methods and triangulation to verify early findings. All of the qualitative studies used interviews and/or focus groups, which were often supplemented with observations, document review, and mapping activities. The use of in situ snowball and convenience sampling; community members as data collectors and cultural guides; collaborative summarisation (review of findings with community members and end-users); and deductive framework analysis expedited the research processes. There were no data on costs., Conclusion: There are a wide range of methods that can be used to deliver timely information about barriers to access. The methods employed in the articles reviewed tended to use traditional data collection approaches in innovative ways., (Copyright © 2023, The Authors.)

Acute-on chronic liver failure (ACLF) has been an intensively debated topic mainly due to the lack of a unified definition and diagnostic criteria. The growing number of publications describing the mechanisms of ACLF development, the progression of the disease, outcomes and treatment has contributed to a better understanding of the disease, however, it has also sparked the debate about this condition. As an attempt to provide medical professionals with a more uniform definition that could be applied to our population, the first Mexican consensus was performed by a panel of experts in the area of hepatology in Mexico. We used the most relevant and impactful publications along with the clinical and research experience of the consensus participants. The consensus was led by 4 coordinators who provided the most relevant bibliography by doing an exhaustive search on the topic. The entire bibliography was made available to the members of the consensus for consultation at any time during the process and six working groups were formed to develop the following sections: 1.- Generalities, definitions, and criteria, 2.- Pathophysiology of cirrhosis, 3.- Genetics in ACLF, 4.- Clinical manifestations, 5.- Liver transplantation in ACLF, 6.- Other treatments., Competing Interests: Declaration of interests None., (Published by Elsevier España, S.L.U.)

Improvisation is a natural occurring phenomenon that is central to social interaction. Yet, improvisation is an understudied area in group processes and intergroup relations. Here we build on theory and research about human herding to study the contributions of improvisation on group efficacy and its biobehavioral underpinnings. We employed a novel multimodal approach and integrative method when observing face-to-face interactions-51 triads (total N = 153) drummed together in spontaneous-free improvisations as a group, while their electrodermal activity was monitored simultaneously with their second-by-second rhythmic coordination on a shared electronic drum machine. Our results show that three hypothesized factors of human herding-physiological synchrony, behavioral coordination, and emotional contagion-predict a sense of group efficacy in its group members. These findings are some of the first to show herding at three levels (physiological, behavioral, and mental) in a single study and lay a basis for understanding the role of improvisation in social interaction., (© 2023 The Authors.

Objective: Sport participation may benefit executive functioning (EF), but EF can also be adversely affected by concussion, which can occur during sport participation. Neural variability is an emerging proxy of brain health that indexes the brain's range of possible responses to incoming stimuli (i.e., dynamic range) and interconnectedness, but has yet to be characterized following concussion among athletes. This study examined whether neural variability was enhanced by athletic participation and attenuated by concussion., Method: Seventy-seven participants (18-25 years-old) were classified as sedentary controls ( n  = 33), athletes with positive concussion history ( n  = 21), or athletes without concussion ( n  = 23). Participants completed tests of attention switching, response inhibition, and updating working memory while undergoing electroencephalography recordings to index neural variability., Results: Compared to sedentary controls and athletes without concussion, athletes with concussion exhibited a restricted whole-brain dynamic range of neural variability when completing a test of inhibitory control. There were no group differences observed for either the switching or working memory tasks., Conclusions: A history of concussion was related to reduced dynamic range of neural activity during a task of response inhibition in young adult athletes. Neural variability may have value for evaluating brain health following concussion.

Background & Aims: Metabolic dysfunction-associated fatty liver disease (MAFLD) is a common complication of obesity with a hallmark feature of hepatic steatosis. Recent data from animal models of MAFLD have demonstrated substantial changes in macrophage composition in the fatty liver. In humans, the relationship between liver macrophage heterogeneity and liver steatosis is less clear., Methods: Liver tissue from 21 participants was collected at time of bariatric surgery and analysed using flow cytometry, immunofluorescence, and H&E microscopy. Single-cell RNA sequencing was also conducted on a subset of samples (n = 3). Intrahepatic triglyceride content was assessed via MRI and tissue histology. Mouse models of hepatic steatosis were used to investigate observations made from human liver tissue., Results: We observed variable degrees of liver steatosis with minimal fibrosis in our participants. Single-cell RNA sequencing revealed four macrophage clusters that exist in the human fatty liver encompassing Kupffer cells and monocyte-derived macrophages (MdMs). The genes expressed in these macrophage subsets were similar to those observed in mouse models of MAFLD. Hepatic CD14 + monocyte/macrophage number correlated with the degree of steatosis. Using mouse models of early liver steatosis, we demonstrate that recruitment of MdMs precedes Kupffer cell loss and liver damage. Electron microscopy of isolated macrophages revealed increased lipid accumulation in MdMs, and ex vivo lipid transfer experiments suggested that MdMs may serve a distinct role in lipid uptake during MAFLD., Conclusions: The human liver in MAFLD contains macrophage subsets that align well with those that appear in mouse models of fatty liver disease. Recruited myeloid cells correlate well with the degree of liver steatosis in humans. MdMs appear to participate in lipid uptake during early stages of MALFD., Impact and Implications: Metabolic dysfunction associated fatty liver disease (MAFLD) is extremely common; however, the early inflammatory responses that occur in human disease are not well understood. In this study, we investigated macrophage heterogeneity in human livers during early MAFLD and demonstrated that similar shifts in macrophage subsets occur in human disease that are similar to those seen in preclinical models. These findings are important as they establish a translational link between mouse and human models of disease, which is important for the development and testing of new therapeutic approaches for MAFLD., Competing Interests: BF is a member of the Scientific Advisory Board and owns stock in Cirius Therapeutics, which is developing an MPC inhibitor for clinical use in treating NASH.

Objectives: To systematically investigate the associations between vision impairment and risk of motor vehicle crash (MVC) involvement, and evaluate vision-related interventions to reduce MVCs., Design: Medline (Ovid), EMBASE and Global Health electronic databases were systematically searched from inception to March 2022 for observational and interventional English-language studies. Screening, data extraction and appraisals using the Joanna Briggs Institute appraisal tools were completed by two reviewers independently. Where appropriate, measures of association were converted into risk ratios (RRs) or ORs for meta-analysis., Participants: Drivers of four-wheeled vehicles of all ages with no cognitive declines., Primary and Secondary Outcomes: MVC involvement (primary) and driving cessation (secondary)., Results: 101 studies (n=778 052) were included after full-text review. 57 studies only involved older drivers (≥65 years) and 85 were in high-income settings. Heterogeneity in the data meant that most meta-analyses were underpowered as only 25 studies, further split into different groups of eye diseases and measures of vision, could be meta-analysed. The limited evidence from the meta-analyses suggests that visual field defects (four studies; RR 1.51 (95% CI 1.23, 1.85); p<0.001; I 2 =46.79%), and contrast sensitivity (two studies; RR 1.40 (95% CI 1.08, 1.80); p=0.01, I 2 =0.11%) and visual acuity loss (five studies; RR 1.21 (95% CI 1.02, 1.43); p=0.03, I 2 =28.49%) may increase crash risk. The results are more inconclusive for available evidence for associations of glaucoma (five studies, RR 1.27 (95% CI 0.67, 2.42); p=0.47; I 2 =93.48%) and cataract (two studies RR 1.15 (95% CI 0.97, 1.36); p=0.11; I 2 =3.96%) with crashes. Driving cessation may also be linked with glaucoma (two studies; RR 1.62 (95% CI 1.20, 2.19); p<0.001, I 2 =22.45%), age-related macular degeneration (AMD) (three studies; RR 2.21 (95% CI 1.47, 3.31); p<0.001, I 2 =75.11%) and reduced contrast sensitivity (three studies; RR 1.30 (95% CI 1.05, 1.61); p=0.02; I 2 =63.19%). Cataract surgery halved MVC risk (three studies; RR 0.55 (95% CI 0.34, 0.92); p=0.02; I 2 =97.10). Ranibizumab injections (four randomised controlled trials) prolonged driving in persons with AMD., Conclusion: Impaired vision identified through a variety of measures is associated with both increased MVC involvement and cessation. Cataract surgery can reduce MVC risk. Despite literature being highly heterogeneous, this review shows that detection of vision problems and appropriate treatment are critical to road safety., Prospero Registration Number: CRD42020172153., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Diabetic retinopathy (DR) is a leading cause of blindness globally. There is growing evidence to support the use of artificial intelligence (AI) in diabetic eye care, particularly for screening populations at risk of sight loss from DR in low-income and middle-income countries (LMICs) where resources are most stretched. However, implementation into clinical practice remains limited. We conducted a scoping review to identify what AI tools have been used for DR in LMICs and to report their performance and relevant characteristics. 81 articles were included. The reported sensitivities and specificities were generally high providing evidence to support use in clinical practice. However, the majority of studies focused on sensitivity and specificity only and there was limited information on cost, regulatory approvals and whether the use of AI improved health outcomes. Further research that goes beyond reporting sensitivities and specificities is needed prior to wider implementation., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Objective: In preclinical models, insulin resistance in the dorsal striatum (DS) contributes to overeating. Although human studies support the concept of central insulin resistance, they have not investigated its effect on consummatory reward-induced brain activity., Methods: Taste-induced activation was assessed in the caudate and putamen of the DS with blood oxygen level-dependent (BOLD) functional magnetic resonance imaging. Three phenotypically distinct groups were studied: metabolically healthy lean, metabolically healthy obesity, and metabolically unhealthy obesity (MUO; presumed to have central insulin resistance). Participants with MUO also completed a weight loss intervention followed by a second functional magnetic resonance imaging session., Results: The three groups were significantly different at baseline consistent with the design. The metabolically healthy lean group had a primarily positive BOLD response, the MUO group had a primarily negative BOLD response, and the metabolically healthy obesity group had a response in between the two other groups. Food craving was predicted by taste-induced activation. After weight loss in the MUO group, taste-induced activation increased in the DS., Conclusions: These data support the hypothesis that insulin resistance and obesity contribute to aberrant responses to taste in the DS, which is only partially attenuated by weight loss. Aberrant responses to food exposure may be a barrier to weight loss., (© 2023 The Obesity Society.

The additional therapeutic effects of regular exercise during a dietary weight loss program in people with obesity and prediabetes are unclear. Here, we show that whole-body (primarily muscle) insulin sensitivity (primary outcome) was 2-fold greater (P = 0.006) after 10% weight loss induced by calorie restriction plus exercise training (Diet+EX; n = 8, 6 women) than 10% weight loss induced by calorie restriction alone (Diet-ONLY; n = 8, 4 women) in participants in two concurrent studies. The greater improvement in insulin sensitivity was accompanied by increased muscle expression of genes involved in mitochondrial biogenesis, energy metabolism and angiogenesis (secondary outcomes) in the Diet+EX group. There were no differences between groups in plasma branched-chain amino acids or markers of inflammation, and both interventions caused similar changes in the gut microbiome. Few adverse events were reported. These results demonstrate that regular exercise during a diet-induced weight loss program has profound additional metabolic benefits in people with obesity and prediabetes.Trial Registration: ClinicalTrials.gov (NCT02706262 and NCT02706288)., (© 2023.

Background: In response to the recommendations of the World Health Organization (WHO) World report on vision, the WHO is developing a Package of Eye Care Interventions (PECI) to support the integration of eye care into health systems within countries. This study was done to systematically review clinical practice guidelines (CPGs) related to age-related macular degeneration (AMD) to provide evidence-based recommendations., Methods: All AMD-related CPGs published between 2010 and 2020 were reviewed and evaluated using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool., Results: Of 3778 CPGs identified, 48 underwent full-text screening and eight underwent quality appraisal. Five National Institute for Health and Care Excellence (NICE, UK) guidelines for AMD were finally selected for data extraction. Intravitreal anti-vascular endothelial growth factor (VEGF) treatment was strongly recommended for advanced, active neovascular AMD based on high-quality evidence. Photodynamic therapy and laser photocoagulation were not recommended as an adjunct to anti-VEGF therapy as first-line treatment for AMD. Recommendations on other interventions, including epiretinal brachytherapy, miniature lens system implantation, and limited macular translocation, were weak and evidence mostly came from low-quality case series studies. Hence these interventions were recommended to be used only with special arrangements or research. Existing evidence on treating geographic atrophy was limited, an implantable miniature telescope might be an effective intervention to improve vision but was still under investigation., Discussion: Current CPGs recommend anti-VEGF therapy for patients with late active neovascular AMD, while other interventions should be used with caution and further researches are warranted.

Hearing and vision impairments are common globally. They are often considered separately in research, and in planning and delivering services. However, they can occur concurrently, termed dual sensory impairment (DSI). The prevalence and impact of hearing and vision impairment have been well-examined, but there has been much less consideration of DSI. The aim of this scoping review was to determine the nature and extent of the evidence on prevalence and impact of DSI. Three databases were searched: MEDLINE, Embase and Global Health (April 2022). We included primary studies and systematic reviews reporting the prevalence or impact of DSI. No limits were placed on age, publication dates, or country. Only studies where the full text was available in English were included. Two reviewers independently screened titles, abstract, full texts. Data were charted by two reviewers independently using a pre-piloted form. The review identified 183 reports of 153 unique primary studies and 14 review articles. Most evidence came from high-income countries (86% of reports). Prevalence varied across reports, as did age groups of participants and definitions used. The prevalence of DSI increased with age. Impact was examined across three broad groups of outcomes-psychosocial, participation, and physical health. There was a strong trend towards poorer outcomes for people with DSI across all categories compared to people with one or neither impairment, including activities of daily living (worse for people with DSI in 78% of reports) and depression (68%). This scoping review highlights that DSI is a relatively common condition with substantial impact, particularly among older adults. There is a gap in evidence from low and middle-income countries. There is a pressing need for a consensus position on the definition(s) of DSI and standardisation of reporting age groups to enable reliable estimates to be ascertained and compared and responsive services developed., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Bright et al.

Context: The Pritikin Program, which provides intensive lifestyle therapy, has been shown to improve cardiometabolic outcomes when provided as a residential program., Objective: The purpose of the present study was to conduct a short-term, randomized, controlled trial to evaluate the feasibility and clinical efficacy of treatment with the Pritikin Program in an outpatient worksite setting., Methods: Cardiometabolic outcomes were evaluated in people with overweight/obesity and ≥2 metabolic abnormalities (high triglycerides, low high-density lipoprotein (HDL) cholesterol, high blood pressure, HbA1c > 5.7%), before and after they were randomized to 6 weeks of standard care (n = 26) or intensive lifestyle therapy, based on the Pritikin Program (n = 28). Participants in the lifestyle intervention group were provided all food as packed-out meals and participated in group nutrition, behavioral education, cooking classes, and exercise sessions 3 times per week at a worksite location., Results: Compared with standard care, intensive lifestyle therapy decreased body weight (-5.0% vs -0.5%), HbA1c (-15.5% vs +2.3%), plasma total cholesterol (-9.8% vs +7.7%), low-density lipoprotein cholesterol (-10.3% vs +9.3%) and triglyceride (-21.7% vs +3.0%) concentrations, and systolic blood pressure (-7.0% vs 0%) (all P values < .02), and increased exercise tolerance (time to exhaustion walking on a treadmill by +23.7% vs +4.5%; P < .001)., Conclusion: This study demonstrates the feasibility and clinical effectiveness of short-term, intensive outpatient lifestyle therapy in people with overweight/obesity and increased risk of coronary heart disease when all food is provided and the intervention is conducted at a convenient worksite setting., (© The Author(s) 2023.

Current yearly seasonal influenza vaccines primarily induce an antibody response directed against the immunodominant but continually diversifying hemagglutinin (HA) head region. These antibody responses provide protection against the vaccinating strain but little cross-protection against other influenza strains or subtypes. To focus the immune response on subdominant but more conserved epitopes on the HA stem that might protect against a broad range of influenza strains, we developed a stabilized H1 stem immunogen lacking the immunodominant head displayed on a ferritin nanoparticle (H1ssF). Here, we evaluated the B cell response to H1ssF in healthy adults ages 18 to 70 in a phase 1 clinical trial (NCT03814720). We observed both a strong plasmablast response and sustained elicitation of cross-reactive HA stem-specific memory B cells after vaccination with H1ssF in individuals of all ages. The B cell response was focused on two conserved epitopes on the H1 stem, with a highly restricted immunoglobulin repertoire unique to each epitope. On average, two-thirds of the B cell and serological antibody response recognized a central epitope on the H1 stem and exhibited broad neutralization across group 1 influenza virus subtypes. The remaining third recognized an epitope near the viral membrane anchor and was largely limited to H1 strains. Together, we demonstrate that an H1 HA immunogen lacking the immunodominant HA head produces a robust and broadly neutralizing HA stem-directed B cell response.

In butterflies and moths, male-killing endosymbionts are transmitted from infected females via their eggs, and the male progeny then perish. This means that successful transmission of the parasite relies on the successful mating of the host. Paradoxically, at the population level, parasite transmission also reduces the number of adult males present in the final population for infected females to mate with. Here we investigate if successful female mating when males are rare is indeed a likely rate-limiting step in the transmission of male-killing Spiroplasma in the African Monarch, Danaus chrysippus . In Lepidoptera, successful pairings are hallmarked by the transfer of a sperm-containing spermatophore from the male to the female during copulation. Conveniently, this spermatophore remains detectable within the female upon dissection, and thus, spermatophore counts can be used to assess the frequency of successful mating in the field. We used such spermatophore counts to examine if altered sex ratios in the D. chrysippus do indeed affect female mating success. We examined two different field sites in East Africa where males were often rare. Surprisingly, mated females carried an average of 1.5 spermatophores each, regardless of male frequency, and importantly, only 10-20% remained unmated. This suggests that infected females will still be able to mate in the face of either Spiroplasma -mediated male killing and/or fluctuations in adult sex ratio over the wet-dry season cycle. These observations may begin to explain how the male-killing mollicute can still be successfully transmitted in a population where males are rare., (© 2023 The Authors.

The COVID-19 pandemic has a major impact on mental well-being and interpersonal relationships. Nonetheless, little is known about the complex interactions between one's overall perceived interpersonal closeness and physiological or psychological aspects of interpersonal functioning. This study aimed to understand the interaction between perceived interpersonal closeness during COVID-19 and interpersonal mechanisms in predicting well-being. We focused on two interpersonal mechanisms, one physiological and the other psychological: (a) prepandemic physiological synchrony, a physiological measure of interpersonal coupling, and (b) peripandemic emotional contagion, one's tendency to "catch" others' emotions. One hundred fifty-five participants took part in the study. Cardiological interbeat interval synchrony was collected 1.5 to 3 years prior to the beginning of the COVID pandemic in two previous lab studies. Participants were recontacted during the pandemic, this time to complete several questionnaires tapping into perceived interpersonal closeness, tendency for emotional contagion, and psychological well-being during COVID. As hypothesized, overall perceived interpersonal closeness was positively related to well-being. Moreover, this effect was moderated by one's tendency for emotional contagion or by physiological synchrony. Thus, individuals with higher emotional contagion scores or higher physiological synchrony had higher well-being if their interpersonal closeness was perceived as greater. Conversely, their well-being was lower if they perceived their interpersonal closeness as weaker. These results emphasize that individuals may be differentially susceptible to the effects of their relationships on their well-being. Future mental health interventions should consider both the quality of one's perceived interpersonal closeness and the extent to which one is sensitive to others' emotional experiences.

Objectives: Low attendance rates for community health services reflect important barriers that prevent people from receiving the care they need. Services and health systems that seek to advance Universal Health Coverage need to understand and act on these factors. Formal qualitative research is the best way to elicit barriers and identify potential solutions, however traditional approaches take months to complete and can be very expensive. We aim to map the methods that have been used to rapidly elicit barriers to accessing community health services and identify potential solutions., Methods and Analysis: We will search MEDLINE, Embase, the Cochrane Library and Global Health for empirical studies that use rapid methods (<14 days) to elicit barriers and potential solutions from intended service beneficiaries. We will exclude hospital-based and 100% remotely delivered services. We will include studies conducted in any country from 1978 to present. We will not limit by language. Two reviewers will independently perform screening and data extraction, with disagreements resolved by a third reviewer. We will tabulate the different approaches used and present data on time, skills and financial requirements for each approach, as well as the governance framework and any strengths and weaknesses presented by the study authors. We will follow Joanna Briggs Institute (JBI) scoping review guidance and report the review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews., Ethics and Dissemination: Ethical approval is not required. We will share our findings in the peer-reviewed literature, at conferences, and with WHO policymakers working in this space., Registration: Open Science Framework (https://osf.io/a6r2m)., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Introduction: There is evidence for increased resistance against the antimicrobials used to treat keratitis. This review aims to provide global and regional prevalence estimates of antimicrobial resistance in corneal isolates and the range of minimum inhibitory concentrations (MIC) with their associated resistance breakpoints., Methods and Analysis: We report this protocol following Preferred Reporting Items for Systematic Review and Meta-Analyses Protocols guidelines. We will conduct an electronic bibliographic search in MEDLINE, EMBASE, Web of Science and the Cochrane Library. Eligible studies will report in any language data for the resistance or MIC for antimicrobials against bacterial, fungal or amoebic organisms isolated from suspected microbial keratitis. Studies that only report on viral keratitis will not be included. There will be no time restrictions on the date of publication. Screening for eligible studies, assessment of risk of bias and data extraction will be conducted by two reviewers independently, using predefined inclusion criteria and prepiloted data extraction forms. We will resolve disagreements between the reviewers by discussion and, if required, a third (senior) reviewer will arbitrate. We will assess the risk of bias using a tool validated in prevalence studies. The certainty of the evidence will be assessed using the Grades of Recommendation, Assessment, Development and Evaluation approach. Pooled proportion estimates will be calculated using a random-effects model. Heterogeneity will be assessed using the I 2 statistic. We will explore differences between Global Burden of Disease regions and temporal trends., Ethics Approval and Dissemination: Ethics approval is not required as this is a protocol for a systematic review of published data. The findings of this review will be published in an open-access, peer-reviewed journal., Prospero Registration Number: CRD42023331126., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Objective: Prior research has revealed potential effects of sports expertise and physical exercise on cognition, though there is limited research examining their effects on the "hot," emotional-processing aspects of executive functioning (e.g., valence and reward processing important for decision-making). The present study aimed to address this gap by examining event-related brain potentials (ERPs) during a reward-processing task in athletes versus non-athletes, while also investigating if sport expertise and exercise influence this electrophysiological response., Method: A total of 45 participants, including 22 athletes (55% women, 45% men) and 23 non-athlete controls (57% women, 43% men) between the ages of 18-27, completed a "virtual T-maze" environment task involving a rewarded forced choice that elicits the reward positivity (Rew-P), an ERP component associated with reward processing. Rew-P peak amplitude was compared between groups, and both sport expertise and frequency of strenuous exercise were investigated as potential predictors of the Rew-P in athletes., Results: No significant Rew-P differences were found between athletes and controls ( t = -1.43, p = .16, d = -.43). However, frequency of strenuous exercise ( β  = -.51, p = .01) and sport expertise ( β  = -.48, p = .01) each accounted for a significant proportion of variability in the Rew-P peak amplitude in athletes., Conclusions: Results indicate that, for young adults, sport expertise and physical exercise may each account for heightened electrophysiological reward sensitivity in athletes. Potential implications are discussed for decision-making, an integral cognitive process in sports that is driven by reward processing, and the role of reward-seeking and motivation in sport proficiency.
