Overall, responses indicate positive learning experiences, and that current and previous ANP/ACP training in the UK does adequately prepare trainees for practice. However, further improvements in curriculum content are suggested. Consistent with the literature, collaborative multidisciplinary teaching, learning and mentorship were identified as key elements in the learning process and role transition.The term 'shock' is used to describe a complex, life-threatening clinical condition that arises from acute circulatory failure. Shock is a pathological state that results when the circulation is unable to deliver sufficient oxygen and nutrients to the cells and tissues. The resulting hypoxia, tissue hypoperfusion and cellular dysfunction can lead to multi-organ failure; if this is not treated in a timely and appropriate manner, it can lead to death. Cell Cycle inhibitor This article gives an introduction to shock with an overview of the condition and its physiological impact on patients. Focusing on the aetiology and underlying causes, discussion will highlight the different types, stages and general pathophysiology of shock, as well as providing a guide to treatment options and nursing interventions.Sam Foster, Chief Nurse, Oxford University Hospitals, reflects on the issues still facing institutions and individuals in developing and supporting ACP roles, and areas to explore for improvement.In the past decade, cyanoacrylate glue has been progressively introduced into the clinical practice of venous access devices used for different purposes. Glue has been used to increase device stabilisation (to reduce the risk of catheter dislodgement), to seal the exit site (to both reduce local bleeding and decrease the risk of bacterial contamination) and to close skin incisions required for the insertion of tunnelled catheters or totally implanted venous ports. For many of these purposes, the efficacy and cost-effectiveness of cyanoacrylate glue has been demonstrated, while some indications are still controversial. This article reports on 10 years of clinical experience with cyanoacrylate glue in a large university hospital, and provides a narrative review of the scientific evidence on the benefits of glue in venous access that has been accumulating over the past decade.The concept of 'bientraitance'(good treatment) of older adults was introduced in Quebec policy a few years prior to the pandemic, and its significance from the perspectives of those directly involved in care remains underexplored. Centring these perspectives, this article presents findings from a study of the meanings, practices and conditions of good treatment. Data was collected at three different residential care settings through world cafés with residents, staff, management, volunteers and family members (n = 61) and through interviews with care aides (n = 13). The study results indicate that those directly involved in care identify good treatment as fundamentally oriented towards developing and maintaining good relationships with residents; as contingent upon interpersonal, material, and organizational factors; and as requiring (more) time. Given the need for radical reform within Quebec's residential care settings revealed by the pandemic, it is imperative that these perspectives inform the changes introduced.

Drug-induced sleep endoscopy-directed lingual tonsillectomy and midline posterior glossectomy have been employed for the treatment of obstructive sleep apnea in children. The purpose of this study is to evaluate outcomes in children undergoing lingual tonsillectomy, midline posterior glossectomy, or combined base of tongue reduction procedures for obstructive sleep apnea.

Case series with chart review.

Tertiary care academic medical center.

A case series was performed with chart review of pediatric patients with obstructive sleep apnea who underwent base of tongue surgery as directed by drug-induced sleep endoscopy. Pre- and postoperative obstructive apnea-hypopnea index (oAHI) was compared. Age, sex, body mass index

score, and medical history were also evaluated.

A total of 168 children were included, with a mean ± SD age of 8.3 ± 3.6 years. Of these patients, 101 underwent lingual tonsillectomy alone; 25, midline posterior glossectomy alone; and 42, both. Their mean oAHI improvement was 3.52 ± 8.39, 2.55 ± 5.59, and 3.70 ± 6.07, respectively. Each surgical group experienced significant improvement in sleep apnea when pre- and postoperative oAHI was compared (

< .01). Overall surgical success, as defined by oAHI <1 (or <5 without clinical symptoms), was 75% (126 patients).

When guided by drug-induced sleep endoscopy, pediatric tongue base surgery can significantly improve oAHI and thus demonstrates promising success in treating pediatric obstructive sleep apnea.

While the underlying mechanisms are complex, the availability of essential dietary nutrients can strongly influence diet selection behavior. The gut microbiome has been shown to metabolize many of these same nutrients, leading to the untested hypothesis that intestinal microbiota may influence diet selection. Here, we show that germ-free mice colonized by gut microbiota from three rodent species with distinct foraging strategies differentially selected diets that varied in macronutrient composition. Specifically, we found that herbivore-conventionalized mice voluntarily selected a higher proteincarbohydrate (PC) ratio diet, while omnivore- and carnivore-conventionalized mice selected a lower PC ratio diet. In support of the long-standing hypothesis that tryptophan—the essential amino acid precursor of serotonin—serves as a peripheral signal regulating diet selection, bacterial genes involved in tryptophan metabolism and plasma tryptophan availability prior to the selection trial were significantly correlated with subsequent voluntary carbohydrate intake. Finally, herbivore-conventionalized mice exhibited larger intestinal compartments associated with microbial fermentation, broadly reflecting the intestinal morphology of their donor species. Together, these results demonstrate that gut microbiome can influence host diet selection behavior, perhaps by mediating the availability of essential amino acids, thereby revealing a mechanism by which the gut microbiota can influence host foraging behavior.The human visual ability to recognize objects and scenes is widely thought to rely on representations in category-selective regions of the visual cortex. These representations could support object vision by specifically representing objects, or, more simply, by representing complex visual features regardless of the particular spatial arrangement needed to constitute real-world objects, that is, by representing visual textures. To discriminate between these hypotheses, we leveraged an image synthesis approach that, unlike previous methods, provides independent control over the complexity and spatial arrangement of visual features. We found that human observers could easily detect a natural object among synthetic images with similar complex features that were spatially scrambled. However, observer models built from BOLD responses from category-selective regions, as well as a model of macaque inferotemporal cortex and Imagenet-trained deep convolutional neural networks, were all unable to identify the real object. This inability was not due to a lack of signal to noise, as all observer models could predict human performance in image categorization tasks. How then might these texture-like representations in category-selective regions support object perception? An image-specific readout from category-selective cortex yielded a representation that was more selective for natural feature arrangement, showing that the information necessary for natural object discrimination is available. Thus, our results suggest that the role of the human category-selective visual cortex is not to explicitly encode objects but rather to provide a basis set of texture-like features that can be infinitely reconfigured to flexibly learn and identify new object categories.Secondary lymphoid organs (SLOs) (including the spleen and lymph nodes [LNs]) are critical both for the maintenance of naive T (TN) lymphocytes and for the initiation and coordination of immune responses. How they age, including the exact timing, extent, physiological relevance, and the nature of age-related changes, remains incompletely understood. We used “time stamping” to indelibly mark newly generated naive T cells (also known as recent thymic emigrants) (RTEs) in mice, and followed their presence, phenotype, and retention in SLOs. We found that SLOs involute asynchronously. Skin-draining LNs atrophied by 6 to 9 mo in life, whereas deeper tissue-draining LNs atrophied by 18 to 20 mo, as measured by the loss of both TN numbers and the fibroblastic reticular cell (FRC) network. Time-stamped RTEs at all ages entered SLOs and successfully completed postthymic differentiation, but the capacity of older SLOs to maintain TN numbers was reduced with aging, and that trait did not depend on the age of TNs. However, in SLOs of older mice, these cells exhibited an emigration phenotype (CCR7loS1P1hi), which correlated with an increase of the cells of the same phenotype in the blood. Finally, upon intradermal immunization, RTEs generated in mice barely participated in de novo immune responses and failed to produce well-armed effector cells detectable in blood as early as by 7 to 8 mo of age. These results highlight changes in structure and function of superficial secondary lymphoid organs in laboratory mice that are earlier than expected and are consistent with the long-appreciated reduction of cutaneous immunity with aging.Meiotic crossover (CO) recombination is tightly regulated by chromosome architecture to ensure faithful chromosome segregation and to reshuffle alleles between parental chromosomes for genetic diversity of progeny. However, regulation of the meiotic chromosome loop/axis organization is poorly understood. Here, we identify a molecular pathway for axis length regulation. We show that the cohesin regulator Pds5 can interact with proteasomes. Meiosis-specific depletion of proteasomes and/or Pds5 results in a similarly shortened chromosome axis, suggesting proteasomes and Pds5 regulate axis length in the same pathway. Protein ubiquitination is accumulated in pds5 and proteasome mutants. Moreover, decreased chromosome axis length in these mutants can be largely rescued by decreasing ubiquitin availability and thus decreasing protein ubiquitination. Further investigation reveals that two ubiquitin E3 ligases, SCF (Skp–Cullin–F-box) and Ufd4, are involved in this Pds5–ubiquitin/proteasome pathway to cooperatively control chromosome axis length.
