This commentary outlines the development of an Inclusion Collaborative in a large health district in Sydney, New South Wales Australia. The Collaborative grew out of ongoing efforts to reduce stigma associated with blood borne viruses while recognising that there are many health conditions and situations where people feel judged when attending services for health care. The formation of the Collaborative drew in health workers in other sectors to create a critical mass of voices calling for stigma reduction, move beyond siloed responses to stigma and to reframe conversations about stigma to a more positive description of "inclusion". The involvement of consumer representatives (paid for their time) was a key principle of the Collaborative. The members of the Collaborative identified the common experience of their clients being 'othered' by the mainstream services and that services can be unwelcoming or not supportive of difference, and therefore create a significant barrier to accessing healthcare. The group considered ways to highlight these issues among colleagues from mainstream services and community members who were not 'othered'. The Collaborative designed and carried out a range of activities including a Festival of Inclusion, a series of seeding grants for staff and consumer-focused initiatives, promotion of diversity days and an audit of compliance with strategic priorities. The Inclusion Collaborative is an example of a structured approach for efforts to reducing stigma that draws on the ambitions of many parts of a large, complex public health service to deliver better outcomes for its staff and consumers.

Aim: Some patients with inflammatory bowel disease (IBD) require subtotal colectomy (STC) with ileostomy. The recent literature reports a significant number of patients who do not undergo subsequent surgery and are resigned to living with a definitive stoma. The aim of this work was to analyse the rate of definitive stoma and the cumulative incidence of secondary reconstructive surgery after STC for IBD in a large national cohort study. Method: A national retrospective study (2013–2021) was conducted on prospectively collected data from the French Medical Information System Database (PMSI). All patients undergoing STC in France were included. The association between definitive stoma and potential risk factors was studied using univariate and multivariate analyses. Results: A total of 1860 patients were included (age 45 ± 9 years; median follow‐up 30 months). Of these, 77% (n = 1442) presented with ulcerative colitis. Mortality and morbidity at 90 days after STC were 5% (n = 100) and 47% (n = 868), respectively. Reconstructive surgery was identified in 1255 patients (67%) at a mean interval of 7 months from STC. Seveny‐four per cent (n = 932) underwent a completion proctectomy with ileal pouch anal anastomosis and 26% (n = 323) an ileorectal anastomosis. Six hundred and five (33%) patients with a definitive stoma had an abdominoperineal resection (n = 114; 19%) or did not have any further surgical procedure (n = 491; 81%). Independent risk factors for definitive stoma identified in multivariate analysis were older age, Crohn's disease, colorectal neoplasia, postoperative complication after STC, laparotomy and a low‐volume hospital. Conclusion: We found that 33% of patients undergoing STC with ileostomy for IBD had definitive stoma. Modifiable risk factors for definitive stoma were laparotomy and a low‐volume hospital.

Genome size varies greatly across the tree of life and transposable elements are an important contributor to this variation. Among vertebrates, amphibians display the greatest variation in genome size, making them ideal models to explore the causes and consequences of genome size variation. However, high-quality genome assemblies for amphibians have, until recently, been rare. Here, we generate a high-quality genome assembly for the dyeing poison frog, Dendrobates tinctorius. We compare this assembly to publicly available frog genomes and find evidence for both large-scale conserved synteny and widespread rearrangements between frog lineages. Comparing conserved orthologs annotated in these genomes revealed a strong correlation between genome size and gene size. To explore the cause of gene-size variation, we quantified the location of transposable elements relative to gene features and find that the accumulation of transposable elements in introns has played an important role in the evolution of gene size in D. tinctorius , while estimates of insertion times suggest that many insertion events are recent and species-specific. Finally, we carry out population-scale mobile-element sequencing and show that the diversity and abundance of transposable elements in poison frog genomes can complicate genotyping from repetitive element sequence anchors. Our results show that transposable elements have clearly played an important role in the evolution of large genome size in D. tinctorius. Future studies are needed to fully understand the dynamics of transposable element evolution and to optimize primer or bait design for cost-effective population-level genotyping in species with large, repetitive genomes.

Amphibians are the most threatened group of vertebrates and are in dire need of conservation intervention to ensure their continued survival. They exhibit unique features including a high diversity of reproductive strategies, permeable and specialized skin capable of producing toxins and antimicrobial compounds, multiple genetic mechanisms of sex determination and in some lineages, the ability to regenerate limbs and organs. Although genomic approaches would shed light on these unique traits and aid conservation, sequencing and assembly of amphibian genomes has lagged behind other taxa due to their comparatively large genome sizes. Fortunately, the development of long‐read sequencing technologies and initiatives has led to a recent burst of new amphibian genome assemblies. Although growing, the field of amphibian genomics suffers from the lack of annotation resources, tools for working with challenging genomes and lack of high‐quality assemblies in multiple clades of amphibians. Here, we analyse 51 publicly available amphibian genomes to evaluate their usefulness for functional genomics research. We report considerable variation in genome assembly quality and completeness and report some of the highest transposable element and repeat contents of any vertebrate. Additionally, we detected an association between transposable element content and climatic variables. Our analysis provides evidence of conserved genome synteny despite the long divergence times of this group, but we also highlight inconsistencies in chromosome naming and orientation across genome assemblies. We discuss sequencing gaps in the phylogeny and suggest key targets for future sequencing endeavours. Finally, we propose increased investment in amphibian genomics research to promote their conservation. [ABSTRACT FROM AUTHOR]

Aim Methods Results Conclusion Diverting ileostomy (DS) after restorative proctocolectomy (RPC) can be omitted in selected patients. Its omission could improve functional outcomes and quality of life (QoL), as has been demonstrated in patients after proctectomy. The aim of this study was to report the impact of diverting ileostomy on functional outcomes and QoL after ileal pouch‐anal anastomosis (IPAA).This was a retrospective study including all patients operated (2015–2020) for RPC with IPAA. Functional outcome was evaluated by validated scores (LARS, Wexner, Öresland, pouch functional score [PFS] and the ileoanal pouch syndrome severity [IPSS] score). Global health‐related QoL was evaluated with the SF‐36. We also analysed demographic characteristics, morbidity, correlation between functional outcomes and QoL.Among 179 eligible patients, 150 responded (84%): S− (no stoma = 78; 52%) and S+ (had stoma = 72; 48%). Overall morbidity and anastomotic leak rates were 46% and 9.3%, respectively without difference between the groups. Medians for the functional scores were comparable between the S− and S+ group, respectively: 18 [12.5–31] versus 18 [11–31], p = 0.48 for LARS; 9 [7–11] versus 9 [7–12], p = 0.23 for Wexner's score; 6 [3–13] versus 8 [5–11], p = 0.22 for Öresland's score, 6 [3–13] versus 6.8 [4–12], p = 0.174 for PFS score, and 40 [35–45] versus 46 [42–51], p = 0.045 for IPSS score. The SF‐36 summary score was comparable between the two groups without any difference in eight specific health dimensions. After propensity score matching, results were still comparable between the two groups for all scores. Linear regression found a significant correlation between all QoL domains and all functional scores (p < 0.001).DS for IPAA does not alter either functional outcomes or QoL and can be omitted in selected patients.

Infanticide is widespread across the animal kingdom, but the physiological drivers of infanticide versus care or neglect are relatively unexplored. Here, we identified salient environmental and physiological antecedents of infanticide in the mimic poison frog ( Ranitomeya imitator ), a biparental amphibian in which female parents feed their tadpoles unfertilized eggs. Specifically, we explored potential environmental cues influencing infant- directed behavior by evaluating changes in the frequency of food provisioning and tadpole mortality after either cross-fostering tadpoles between family units or displacing tadpoles within the terraria of their parents. We found that changes in offspring location reduce care and increase infanticide. Specifically, parents fed their displaced offspring less and, in some instances, tadpole mortality increased. We also investigated whether care and infanticide were related to changes in steroid hormone concentrations in an unfamiliar setting. Infanticide of fertilized eggs and hatchlings in the new territory included cannibalism and was associated with lower testosterone concentrations, but not with changes in corticosterone. Overall, our results support earlier findings that familiarity with offspring location drives parental investment in poison frogs, while indicating an association between low androgen levels and infanticidal behavior in an amphibian., Highlights: Offspring location drives parental decisions of care vs. infanticide.In novel territories, adults cannibalize conspecific, unrelated young.Lower circulating testosterone in novel territory is associated with infanticide.

Background: Amphibians represent an important evolutionary transition from aquatic to terrestrial environments and they display a large variety of complex behaviors despite a relatively simple brain. However, their brain activity is not as well characterized as that of many other vertebrates, partially due to physiological traits that have made electrophysiology recordings difficult to perform in awake and moving animals., New Method: We implanted flexible mesh electronics in the cane toad ( Rhinella marina ) and performed extracellular recordings in the telencephalon of anesthetized toads and partially restrained, awake toads over multiple days., Results: We recorded brain activity over five consecutive days in awake toads and over a 15 week period in a toad that was anesthetized during recordings. We were able to perform spike sorting and identified single- and multi-unit activity in all toads., Comparison With Existing Methods: To our knowledge, this is the first report of a modern method to perform electrophysiology in non-paralyzed toads over multiple days, though there are historical references to short term recordings in the past., Conclusions: Implementing flexible mesh electronics in amphibian species will allow for advanced studies of the neural basis of amphibian behaviors., Competing Interests: 10.COMPETING INTERESTS The authors declare no competing or financial interests.

Parent-offspring interactions constitute the first contact of many newborns with their environment, priming community assembly of microbes through priority effects. Early exposure to microbes can have lasting influences on the assembly and functionality of the host's microbiota, leaving a life-long imprint on host health and disease. Studies of the role played by parental care in microbial acquisition have primarily focused on humans and hosts with agricultural relevance. Anuran vertebrates offer the opportunity to examine microbial community composition across life stages as a function of parental investment. In this study, we investigate vertical transmission of microbiota during parental care in a poison frog (Family Dendrobatidae ), where fathers transport their offspring piggyback-style from terrestrial clutches to aquatic nurseries. We found that substantial bacterial colonization of the embryo begins after hatching from the vitelline envelope, emphasizing its potential role as microbial barrier during early development. Using a laboratory cross-foster experiment, we demonstrated that poison frogs performing tadpole transport serve as a source of skin microbes for tadpoles on their back. To study how transport impacts the microbial skin communities of tadpoles in an ecologically relevant setting, we sampled frogs and tadpoles of sympatric species that do or do not exhibit tadpole transport in their natural habitat. We found more diverse microbial communities associated with tadpoles of transporting species compared to a non-transporting frog. However, we detected no difference in the degree of similarity between adult and tadpole skin microbiotas, based on whether the frog species exhibits transporting behavior or not. Using a field experiment, we confirmed that tadpole transport can result in the persistent colonization of tadpoles by isolated microbial taxa associated with the caregiver's skin, albeit often at low prevalence. This is the first study to describe vertical transmission of skin microbes in anuran amphibians, showing that offspring transport may serve as a mechanism for transmission of parental skin microbes. Overall, these findings provide a foundation for further research on how vertical transmission in this order impacts host-associated microbiota and physiology., Competing Interests: Declaration of Interests The authors declare no competing interests.

Motor function is a critical aspect of social behavior in a wide range of taxa. The transcription factor FoxP2 is well studied in the context of vocal communication in humans, mice, and songbirds, but its role in regulating social behavior in other vertebrate taxa is unclear. We examined the distribution and activity of FoxP2-positive neurons in tadpoles of the mimic poison frog ( Ranitomeya imitator ). In this species, tadpoles are reared in isolated plant nurseries and are aggressive to other tadpoles. Mothers provide unfertilized egg meals to tadpoles that perform a begging display by vigorously vibrating back and forth. We found that FoxP2 is widely distributed in the tadpole brain and parallels the brain distribution in mammals, birds, and fishes. We then tested the hypothesis that FoxP2-positive neurons would have differential activity levels in begging or aggression contexts compared to non-social controls. We found that FoxP2-positive neurons showed increased activation in the striatum and cerebellum during begging and in the nucleus accumbens during aggression. Overall, these findings lay a foundation for testing the hypothesis that FoxP2 has a generalizable role in social behavior beyond vocal communication across terrestrial vertebrates.

Background: The oral microbiome comprises distinct microbial communities that colonize diverse ecological niches across the oral cavity, the composition of which are influenced by nutrient and substrate availability, host genetics, diet, behavior, age, and other diverse host and environmental factors. Unlike other densely populated human-associated microbial ecosystems (e.g., gut, urogenital), the oral microbiome is regularly and directly exposed to the external environment and is therefore likely less stable over time. Cross sectional studies of the oral microbiome capture a glimpse of this temporal dynamism, yet a full appreciation of the relative stability, robusticity, and spatial structure of the oral environment is necessary to understand the role of microbial communities in promoting health or disease., Results: Here we investigate the spatial and temporal stability of the oral microbiome over three sampling time points in the context of HIV infection and exposure. Individual teeth were sampled from a cohort of 565 Nigerian children with varying levels of tooth decay severity (i.e., caries disease). We collected 1,960 supragingival plaque samples and characterized the oral microbiome using a metataxonomic approach targeting an approximately 478 bp region of the bacterial rpo C gene. We found that both infection and exposure to HIV have significant effects on the stability of the supragingival plaque microbiome at both the spatial and temporal scale. Specifically, we detect (1) significantly lower taxonomic turnover of the oral community among exposed and infected children compared to unexposed children, (2) we find that HIV infection homogenizes the oral community across the anterior and posterior dentition, and (3) that impaired immunity (i.e., low CD4 count) and low taxonomic turnover over time in children living with HIV is associated with higher frequency of cariogenic taxa including Streptococcus mutans ., Conclusions: Our results document substantial community fluctuations over time in children unexposed to HIV independent of oral health status. This suggests that the oral community, under typical conditions, rapidly adapts to environmental perturbations to maintain homeostasis and that long-term taxonomic rigidity is a signal of community dysfunction, potentially leading to a higher incidence of oral disease including caries., Competing Interests: Competing interests The authors declare that they have no competing interests Additional Declarations: No competing interests reported.

More than a century ago, Charles Darwin hypothesized that the empathy-like phenotype is a phylogenetically widespread phenomenon. This idea remains contentious, due to the challenges of empirically examining emotions, and few investigations among non-mammalian vertebrates. We provide support for Darwin's hypothesis by discovering partial evidence for the most ancestral form of empathy, emotional contagion (i.e. matching another individual's emotional state), in the pair bonding mimetic poison frog, Ranitomeya imitator . We found that male corticosterone, a physiological biomarker of stress, positively correlates with female partners in experimental and semi-natural conditions. This does not appear to coincide with behavioural state-matching. However, it is specific to female partners relative to familiar female non-partners, and is independent of effects that commonly confound studies on emotional contagion. Furthermore, this physiological state-matching is irrespective of partnership longevity or lifetime reproductive output. These results physiologically indicate socially selective emotional contagion in a monogamous amphibian, and paradigms that elicit coinciding neural and behavioural indicators and morphogenic co-variation are needed for further corroboration. Further studies on ancestral forms of empathy in non-mammalian vertebrates are warranted., Competing Interests: We declare we have no competing interests., (© 2024 The Authors.)

The behavioral, sensory, and neural bases of vertebrate navigation are primarily described in mammals and birds. However, we know much less about navigational abilities and mechanisms of vertebrates that move on smaller scales, such as amphibians. To address this knowledge gap, we conducted an extensive field study on navigation in the cane toad, Rhinella marina . First, we performed a translocation experiment to describe how invasive toads in Hawai'i navigate home following displacements of up to one kilometer. Next, we tested the effect of olfactory and magnetosensory manipulations on homing, as these senses are most commonly associated with amphibian navigation. We found that neither ablation alone prevents homing, suggesting that toad navigation is multimodal. Finally, we tested the hypothesis that the medial pallium, the amphibian homolog to the hippocampus, is involved in homing. By comparing neural activity across homing and non-homing toads, we found evidence supporting the involvement of the medial pallium, lateral pallium, and septum in navigation, suggesting a conservation of neural structures supporting navigation across vertebrates. Our study lays the foundation to understand the behavioral, sensory, and neural bases of navigation in amphibians and to further characterize the evolution of behavior and neural structures in vertebrates., Competing Interests: Competing interests The authors declare no competing or financial interests.

Ant behavior relies on a collection of natural products, from following trail pheromones during foraging to warding off potential predators. How nervous systems sense these compounds to initiate a behavioral response remains unclear. Here, we used Caenorhabditis elegans chemotaxis assays to investigate how ant compounds are detected by heterospecific nervous systems. We found that C. elegans avoid extracts of the pavement ant ( Tetramorium immigrans ) and either osm-9 or tax-4 ion channels are required for this response. These experiments were conducted in an undergraduate laboratory course, demonstrating that new insights into interspecies interactions can be generated through genuine research experiences in a classroom setting., Competing Interests: The authors declare that there are no conflicts of interest present., (Copyright: © 2024 by the authors.)

Introduction: Although effective, conventional excisional haemorrhoidectomy (CEH) is associated with significant postoperative pain. Novel techniques such as transanal haemorrhoidal dearterialization (THD) are suggested to reduce pain but may result in higher recurrence rates. We aimed to compare short- and long-term outcomes of CEH and THD in the present meta-analysis., Methods: A PRISMA-compliant meta-analysis was performed, searching PubMed, Embase, and CENTRAL databases for randomised controlled trials (RCTs) from 1995 to December 2022. The primary objective was recurrence. Secondary objectives included complication rates, length of stay (LOS), operative time, and time to return to baseline. Random-effects models were used to calculate pooled effect size estimates. Subgroup analysis was also performed., Results: A total of 6 RCTs encompassing 465 patients were captured. There were 142 (59%) males in the CEH group and 129 (54%) in the THD group. On random-effects analysis, THD had a higher recurrence rate (odds ratio = 2.76, 95% confidence interval [CI] = 1.03-7.38, p = 0.04) albeit a shorter return to baseline compared to CEH (mean difference = -14.05 days, 95% CI = -20.38 to -7.72, p &lt; 0.0001). There were no differences in bleeding (p = 0.12), urinary retention (p = 0.97), incontinence (p = 0.41), anal stenosis (p = 0.19), thrombosed residual haemorrhoids (p = 0.16), operating time (p = 0.19), or LOS (p = 0.22). Results remained similar on subgroup analysis., Conclusions: CEH is associated with lower recurrence but similar complication rates to THD, although patients take longer to return to baseline function postoperatively., (© 2024 S.
