This model provides a baseline context in which other intra- and inter-group processes act, tipping the balance toward or away from conflict. We discuss future directions for research into the ecological factors shaping the evolution of inter-group interactions. This article is part of the theme issue 'Intergroup conflict across taxa'.Across vertebrate species, intergroup conflict confronts individuals with a tension between group interests best served by participation in conflict and personal interest best served by not participating. Here, we identify the neurohormone oxytocin as pivotal to the neurobiological regulation of this tension in distinctly different group-living vertebrates, including fishes, birds, rodents, non-human primates and humans. In the context of intergroup conflict, a review of emerging work on pro-sociality suggests that oxytocin and its fish and birds homologues, isotocin and mesotocin, respectively, can elicit participation in group conflict and aggression. This is because it amplifies (i) concern for the interests of genetically related or culturally similar 'in-group' others and (ii) willingness to defend against outside intruders and enemy conspecifics. Across a range of social vertebrates, oxytocin can induce aggressive behaviour to 'tend-and-defend' the in-group during intergroup contests. This article is part of the theme issue 'Intergroup conflict across taxa'.Out-group conflict is rife in the natural world, occurring from primates to ants. Traditionally, research on this aspect of sociality has focused on the interactions between groups and their conspecific rivals, investigating contest function and characteristics, which group members participate and what determines who wins. In recent years, however, there has been increasing interest in the consequences of out-group conflict. In this review, we first set the scene by outlining the fitness consequences that can arise immediately to contest participants, as well as a broader range of delayed, cumulative and third-party effects of out-group conflict on survival and reproductive success. For the majority of the review, we then focus on variation in these fitness consequences of out-group conflict, describing known examples both between species and between populations, groups and individuals of the same species. Throughout, we suggest possible reasons for the variation, provide examples from a diverse array of taxa, and suggest what is needed to advance this burgeoning area of social evolution. This article is part of the theme issue 'Intergroup conflict across taxa'.Purpose The decision-making of how to treat urinary infection stones was complicated by the difficulty in preoperative diagnosis of these stones. Hence, we developed machine learning (ML) models that can be leveraged to discriminate between infection and noninfection stones in urolithiasis patients before treatment. Materials and Methods We enrolled 462 patients with urinary stones and randomly stratified them into training (80%) and testing sets (20%). ML models were constructed using five algorithms (decision tree, random forest classifier [RFC], extreme gradient boosting, categorical boosting, and adaptive boosting) and 15 preoperative variables and were compared with conventional logistic regression (LR) analysis. Performance measurement was the area under the receiver operating characteristic curve (AUC) in the testing set. We also analyzed the importance of 15 features on the prediction of infection stones in each ML model. Results Sixty-two (13.4%) patients with infection stones were included in the study. On the testing set, all the five ML models demonstrated strong discrimination (AUC 0.892-0.951). The RFC model was chosen as the final model [AUC 0.951 (95% confidence interval, CI, 0.934-0.968); sensitivity 0.906; specificity 0.924], significantly outperforming the traditional LR model [AUC 0.873 (95% CI 0.843-0.904)]. Gender, urine white blood cell counts, and urine pH level were the top 3 important features. Conclusion Our RFC model was the first model for the preoperative identification of infection stones with superior predictive performance. This novel model could be useful for risk assessment and decision support for infection stones.The link between engagement in non-suicidal self-injury (NSSI)-related activities on SNS (e.g. viewing, commenting, sharing and uploading NSSI content) with body image and NSSI behaviour remains under researched in adolescents with EDs. The main aim of the current research was to examine associations between NSSI-related activities on SNS with body image and NSSI behaviour severity among female adolescents diagnosed with an ED. find more A total of 52 female adolescents (mean age = 15.35 years, SD = 1.49) diagnosed with an ED completed self-report questionnaires related to NSSI behaviour, SNS usage and body image. Participants were divided into two groups low NSSI behaviour severity (from 0 to 10 NSSI behaviours; n = 28) and high NSSI behaviour severity (more than ten NSSI behaviours; n = 24). Within the high NSSI severity group, individuals that comment and share NSSI online content significantly reported higher negative body image. A hierarchical binary logistic regression showed that the frequency of NSSI online content on SNS emerged as significant predictor of NSSI behaviour severity within last year after controlling for body image and searching for ED content on SNS. Our findings suggest that not only searching for ED content, but also being daily engaged in NSSI online activities may increase the risk of NSSI behaviour severity in female adolescents with EDs.A large proportion of peripheral vascular patients worldwide experience unplanned hospital readmissions after inpatient vascular surgery. This review was conducted to identify acute care and post-discharge interventions that may help in reducing unplanned vascular surgery readmissions. A computer-based search of four databases was conducted July 2021 for original research reports published 2000 to 2021. Eight studies met inclusion criteria, with interventions including multidisciplinary care teams, advance practice provider discharge coordination, individualized case management, home care nursing, early primary care provider or telephone follow-up, and telehealth driven follow up evaluated. Some reductions in readmission rates were associated with most interventions but were inconsistent across studies. Further research is necessary to clarify and validate these findings, incorporate patient perspectives, and explore the role of technology-based interventions. This work is key to improving the patient's experience, reduce healthcare costs, and strengthen the quality of vascular surgery care.Addressing breastfeeding issues enables mothers to reach their breastfeeding goals. We embedded a breastfeeding consultation service run by a pediatrician/International Board Certified Lactation Consultant (MD/IBCLC) in a medical home. This mixed-methods study investigated breastfeeding preparedness and the service's perceived benefits. Mothers with breastfeeding issues/concerns identified at well-baby appointments were referred to the service. Telephone interviews and chart reviews were conducted with 28 participating mothers approximately 1 month after the visits. Breastfeeding Self-Efficacy Scale scores improved significantly from the time of the in-person appointment to 1 month later. Most mothers felt unprepared for breastfeeding despite prenatal efforts. Trust in the pediatrician's recommendation, easy access, and insurance coverage were key factors in seeking the service. Reassurance provided by the MD/IBCLC increased mothers' confidence to breastfeed. The COVID-19 pandemic heightened feelings of isolation and anxiety due to lack of hands-on support from friends and family during the birth hospitalization and when at home.

Waiting times for arthroplasty surgery in Northern Ireland are among the longest in the NHS, which have been further lengthened by the onset of the COVID-19 global pandemic in March 2020. The Department of Health in Northern Ireland has announced a new Elective Care Framework (ECF), with the framework proposing that by March 2026 no patient will wait more than 52 weeks for inpatient/day case treatment. We aimed to assess the feasibility of achieving this with reference to total hip arthroplasty (THA) and total knee arthroplasty (TKA).

Mathematical modelling was undertaken to calculate when the ECF targets will be achieved for THA and TKA, as well as the time when waiting lists for THA and TKA will be cleared. The number of patients currently on the waiting list and percentage operating capacity relative to pre-COVID-19 capacity was used to determine future projections.

As of May 2021, there were 3,757 patients awaiting primary THA and 4,469 patients awaiting primary TKA in Northern Ireland. Prior to Aprved with regard to THA and TKA. Waiting times for THA and TKA surgery in Northern Ireland are likely to remain greater than 52 weeks for most of this decade.

Flow cytometry is used in many areas of science, in particular biotechnology and medicine, but also in industrial applications. Flow cytometry can identify multiple phenotypic subsets from a mixture, select a single cell and even isolate that cell by a process called cell sorting. The field is currently undergoing dramatic changes. We are moving rapidly from the polychromic flow cytometry that has been the go-to technology for 45 years to spectral flow cytometry, which is now the most significant change in nearly half a century of flow cytometry. With change comes opportunity. Even spectral flow cytometry will morph into second-generation spectral flow cytometry within 5 years. New, exciting features will open up molecular diagnostics and physiology to flow cytometry.Significance Imaging free radicals, including reactive oxygen species and reactive nitrogen species, can be useful for understanding the pathology of diseases in animal disease models, as they are related to various physiological functions or diseases. Among the methods used for imaging free radicals, Overhauser-enhanced magnetic resonance imaging (OMRI) has a short image acquisition time and high spatial resolution. Therefore, OMRI is used to obtain various biological parameters. In this study, we review the methodology for improving the biological OMRI system and its applications. Recent Advances The sensitivity of OMRI systems has been enhanced significantly to allow the visualization of various biological parameters, such as redox state, partial oxygen pressure, and pH, in different body parts of small animals, using spin probes. Furthermore, both endogenous free radicals and exogenous free radicals present in drugs can be visualized using OMRI. Critical Issues To acquire accurate biological parameters at a high resolution, it is essential to increase the electron paramagnetic resonance (EPR) excitation efficiency and achieve a high enhancement factor. In addition, the size and magnetic field strength also need to be optimized for the measurement target. Future Directions The advancement of in vivo OMRI techniques will be useful for understanding the pathology, diagnosis, and evaluation of therapeutic effects of drugs in various disease models.
