    Abstract The bioengineering applications of cells, such as cell printing and multicellular assembly, are directly limited by cell damage and death due to a harsh environment. Improved cellular robustness thus motivates investigations into cell encapsulation, which provides essential protection. Here we target the cell-surface glycocalyx and cross-link two layers of DNA nanorods on the cellular plasma membrane to form a modular and programmable nanoshell. We show that the DNA origami nanoshell modulates the biophysical properties of cell membranes by enhancing the membrane stiffness and lowering the lipid fluidity. The nanoshell also serves as armor to protect cells and improve their viability against mechanical stress from osmotic imbalance, centrifugal forces, and fluid shear stress. Moreover, it enables mediated cell-cell interactions for effective and robust multicellular assembly. Our results demonstrate the potential of the nanoshell, not only as a cellular protection strategy but also as a platform for cell and cell membrane manipulation.

    Abstract Background: Exclusive enteral nutrition (EEN) induces remission and mucosal healing in patients with Crohn's disease, but the mechanism of action remains unknown.
    Aim: To outline current understanding of the mechanisms of action of EEN.
    Methods: From a comprehensive literature search, published data were critically examined in a narrative review.
    Results: Multiple potential mechanisms of action have been identified. EEN optimises nutritional status. Differences in gut microbiota in terms of overall diversity and taxonomic community structure are observed between responders and non-responders to EEN. Therapy with EEN alters microbial metabolites (including faecal short-chain fatty acids, amino acids, branched-chain amino acids and sulphide) and faecal pH. Epithelial effects and restoration of barrier function, as well as changes in mucosal cytokine profiles and T-cell subsets are observed in responders to EEN. The impact of inclusion or exclusion of specific dietary components may be of importance, but putative detrimental components are found in many formulas. A major challenge in interpreting these findings is that they often contradict or change in opposite directions to what is considered 'beneficial'. It is difficult to differentiate between the observations following EEN being driven by EEN per se and those associated with resolving inflammation.
    Conclusions: The mechanisms of action of EEN are likely to involve a complex interplay between host mucosal immune response and luminal environment, but the identity of key factors remains poorly understood. A better definition of pathogenic factors may aid in developing more targeted dietary treatment and provide insights into the pathogenesis of Crohn's disease.

    Abstract This article investigates how macro-level structures condition the sources of socioeconomic inequalities in health. Drawing on multiple social science disciplines, the authors develop theoretically grounded propositions about how different types of welfare states, varieties of capitalism, and social structures give rise to cross-national variations in the sources of health inequalities. They consider how these macro-level structures affect the distribution of five key resources important to health, estimate the relative contribution that each resource makes to health inequalities, and compare those contributions in 21 developed democracies. Moving beyond a current literature focused on welfare states, the authors show how different types of political economies and social structures also condition the health gradient. This research carries implications for policy and suggests agendas for further investigation into the relationship between macro-level structures and inequalities in health.

    Abstract Terrible triad injuries are typically treated surgically to restore elbow stability, as the radial head acts as a secondary stabilizer to valgus stress, while the coronoid provides stability against posterior elbow dislocations. The lateral ulnar collateral ligament (LUCL) is also commonly injured in terrible triad of the elbow injuries, and if not repaired, leads to posterolateral rotatory instability. Depending on the fracture pattern and size, the radial head fracture may be treated with open reduction internal fixation (ORIF), arthroplasty, or excision, whereas the coronoid fracture is most commonly treated with ORIF. If treated, these injuries are managed prior to LUCL fixation to avoid stressing the LUCL repair. We describe a technique for treatment of a LUCL injury with a suture button. When repairing the LUCL, a Kocher approach is used to visualize the LUCL footprint, which is then reattached to the insertion point on the lateral epicondyle using a suture button. The purpose of this study was to provide a step-by-step approach to using this surgical technique and an associated postoperative protocol.

    Abstract While canine lymphoma is a relatively common and important disease seen by veterinarians, there are limited comprehensive reviews of the literature regarding the remission and survival times following chemotherapy, and the associated prognostic factors. This comprehensive thematic review covers the available veterinary literature covering treatment outcomes and identified prognostic factors. A lack of standardised approaches to evaluate and report the outcomes was identified, including factors that would alter the duration of responses by weeks, or occasionally months. After publication of the suggested reporting criteria, this has improved but is still not uniformly applied. The prognostic factors included for evaluation varied from as few as three to seventeen, with over 50 studies using only univariate analysis. Individual papers reported much longer outcomes than others, but assessing the outcomes overall, there has been minimal change over the last 40 years. This supports the belief that novel approaches for lymphoma therapy will be required to substantively improve outcomes.

    Abstract Morphometric studies of 3D micro CT-scanned images can provide insights into the evolution of the brain and sensory structures but such data are still scarce for the most diverse mammalian order of rodents. From reviewed and new data, we tested for convergence to extreme aridity and high elevation in the sensory and brain morphology of rodents, from morphometric data from micro-CT X-ray scans of 174 crania of 16 species of three distantly related African murid (soft-furred mice, Praomyini, laminate-toothed rats, Otomyini, and gerbils, Gerbillinae) clades and one North American cricetid (deer mice and white-footed mice, Peromyscus) clade. Recent studies demonstrated convergent evolution acting on the oval window area of the cochlea (enlarged in extremely arid-adapted species of Otomyini and Gerbillinae) and on endocranial volume (reduced in high elevation taxa of Otomyini and Peromyscus). However, contrary to our predictions, we did not find evidence of convergence in brain structure to aridity, or in the olfactory/respiratory system (turbinate bones) to high elevation. Brain structure differed, particularly in the petrosal lobules of the cerebellum and the olfactory bulbs, between Otomyini and Gerbillinae, with extreme arid-adapted species in each clade being highly divergent (not convergent) from other species in the same clade. We observed greater "packing" of the maxillary turbinate bones, which have important respiratory functions, in Peromyscus mice from high and low elevations compared to the high-elevation African Praomyini, but more complex patterns within Peromyscus, probably related to trade-offs in respiratory physiology and heat exchange in the nasal epithelium associated with high-elevation adaptation.

    Abstract Prior studies have demonstrated a high incidence of ankle osteoarthritis (OA) in patients undergoing total knee arthroplasty (TKA) as well as inferior outcomes in the setting of ankle OA or hindfoot malalignment. Little is known about the effect of the 2 most common surgical treatments for ankle OA, ankle arthrodesis and total ankle arthroplasty (TAA) on TKA. This hypothesis is that the preservation of ankle motion afforded by total ankle arthroplasty may reduce pathologic stresses across the knee joint. This study compares outcomes of patients who underwent both TKA and TAA versus those that underwent TKA and ankle arthrodesis. We retrospectively reviewed a cohort of patients who had undergone TKA and either TAA or ankle arthrodesis at this institution, examining knee injury and OA outcome scores, foot and ankle ability measure scores, revision surgery, knee range of motion, and pain. There were 69 eligible subjects, 13 who had undergone total knee arthroplasty and total ankle arthroplasty and 56 who had undergone TKA and ankle arthrodesis. No significant differences were observed in KOOS Jr scores, FAAM scores, incidence of revision, knee range of motion, or pain at final follow up (p > .05). Mean follow-up time was 46 months after both surgeries were completed. Equivalent outcomes were observed between the 2 groups. The presence of a TKA should not alter the indications for treatment of ankle OA with TAA versus arthrodesis. Further studies are needed as these relatively rare concomitant procedures are likely to become more common in the future.

    Abstract To better understand functional morphological adaptations to high elevation (> 3000 m above sea level) life in both North American and African mountain-associated rodents, we used microCT scanning to acquire 3D images and a 3D morphometric approach to calculate endocranial volumes and skull lengths. This was done on 113 crania of low-elevation and high-elevation populations in species of North American cricetid mice (two Peromyscus species, n = 53), and African murid rodents of two tribes, Otomyini (five species, n = 49) and Praomyini (four species, n = 11). We tested two distinct hypotheses for how endocranial volume might vary in high-elevation populations: the expensive tissue hypothesis, which predicts that brain and endocranial volumes will be reduced to lessen the costs of growing and maintaining a large brain; and the brain-swelling hypothesis, which predicts that endocranial volumes will be increased either as a direct phenotypic effect or as an adaptation to accommodate brain swelling and thus minimize pathological symptoms of altitude sickness. After correcting for general allometric variation in cranial size, we found that in both North American Peromyscus mice and African laminate-toothed (Otomys) rats, highland rodents had smaller endocranial volumes than lower-elevation rodents, consistent with the expensive tissue hypothesis. In the former group, Peromyscus mice, crania were obtained not just from wild-caught mice from high and low elevations but also from those bred in common-garden laboratory conditions from parents caught from either high or low elevations. Our results in these mice showed that brain size responses to elevation might have a strong genetic basis, which counters an opposite but weaker environmental effect on brain volume. These results potentially suggest that selection may act to reduce brain volume across small mammals at high elevations but further experiments are needed to assess the generality of this conclusion and the nature of underlying mechanisms.
