Atrial arrhythmias are highly prevalent in the aging Fontan population and contribute importantly to morbidity and mortality. DL-AP5 Although the most common arrhythmia is scar-based intra-atrial re-entrant tachycardia, various other arrhythmias may occur, including focal atrial tachycardia, atrioventricular node-dependent tachycardias, and atrial fibrillation. The type and prevalence of atrial arrhythmia is determined, in part, by the underlying congenital defect and variant of Fontan surgery. Although the cumulative incidence of atrial tachyarrhythmias has decreased substantially from the atriopulmonary anastomosis to the more recent total cavopulmonary-connection Fontan, the burden of atrial arrhythmias remains substantial. Management is often multifaceted and can include anticoagulation, anti-arrhythmic drug therapy, pacing, and cardioversion. Catheter ablation plays a key role in control of arrhythmia. Risks and benefits must be carefully weighed. Among the important considerations are the clinical burden of arrhythmia, ventricular function, hemodynamic stability in tachycardia, suspected arrhythmia mechanisms, risks associated with anaesthesia, venous access, approaches to reaching the pulmonary venous atrium, and accompanying comorbidities. Careful review of surgical notes, electrocardiographic tracings, and advanced imaging is paramount, with particular attention to anatomic abnormalities such as venous obstructions and displaced conduction systems. Despite numerous challenges, ablation of atrial arrhythmias is effective in improving clinical status. Nevertheless, onset of new arrhythmias is common during long-term follow-up. Advanced technologies, such as high-density mapping catheters and remote magnetic guided ablation, carry the potential to further improve outcomes. Fontan patients with atrial arrhythmias should be referred to centres with dedicated expertise in congenital heart disease including catheter ablation, anaesthesia support, and advanced imaging.Global demand for major surgery is rising as a consequence of a growing ageing population, and clinically applicable approaches to perioperative risk reduction have never been more needed. Prehabilitation aims to optimise aerobic capacity and address modifiable risk factors before surgery to improve postoperative outcomes. Given the inherently high-risk nature of vascular surgery and the frequently high-acuity frail vascular surgical population, the potential to introduce an intervention into the surgical pathway that may reduce postoperative complications cannot be overlooked. The aim of this review is to examine the current evidence base for prehabilitation in patients awaiting vascular surgery, and to summarise the potential benefits, pitfalls, and practicalities of this emerging perioperative intervention. There is a paucity of high-quality research specifically aimed at prehabilitation for patients undergoing vascular surgery, both peripheral and aortic, making it difficult to draw definitive conclusions upon which to base a change in practice. Currently, evidence is taken from small, often single-centre, heterogeneous studies that vary significantly from each other, meaning that the optimal exercise regimen for patients awaiting vascular surgery has yet to be defined. Establishing the impact of prehabilitation on outcomes for vascular patients is important as the effectiveness of preoperative exercise training is likely to vary between surgical interventions and patient populations. However, extrapolation from other cohorts is possible and indeed forms the basis of many current prehabilitation programmes. Given the success of prehabilitation in other surgical groups, it has potential to become an important future research target for patients awaiting vascular surgery.In the current era, 5%-10% of Fontan patients die or need a transplant in childhood, and approximately 50% will experience the same fate by age 40 years. Heart transplant (HTx) can be successful for selected children and adults with Fontan circulatory failure of any mechanism, with a 1-year post-transplant survival rate approaching 90% in children and 80% in the largest single-centre adult Fontan HTx experience. Protein-losing enteropathy and plastic bronchitis can be expected to resolve post-transplant, and limited data suggest patients with Fontan-associated liver disease who survive HTx can expect improvement in liver health. Early Fontan failure, within 12 months of Fontan completion, is not easily rescued by HTx, and late referrals and failure to refer adult patients remain problematic. Very little is known about the numbers of patients who are not referred, are turned down following assessment for HTx, or die on the waiting list-numbers that are needed to understand the complete picture of HTx in the Fontan population and to identify where best to focus quality-improvement efforts. Recent revisions to listing prioritization in Canada with considerations specific to the Fontan population aim to mitigate the fact that the status-listing criteria are not tailored to the congenital heart population. Transplanting high-risk children prior to Fontan completion, developing adult congenital heart disease transplant centres with expertise that can also offer combined heart-liver transplant when appropriate, and improving single-ventricle mechanical support options and criteria for both adults and children may help mitigate the early post-listing mortality.There have been significant advancements in endovascular technology over the past decade. Increasingly complex disease processes are being addressed in a less invasive fashion, while still relying on standard 2-dimensional greyscale fluoroscopy imaging to guide the procedures. With the advent of flat-panel detectors as standard on fluoroscopy units and the use of fluoroscopy cone-beam computed tomography, the development of improved imaging tools has occurred that will help improve the imaging modalities used to perform these endovascular procedures. Fusion imaging, the overlay of preoperative 3-dimensional computed tomographic images, helps interventionalists perform endovascular procedures. Building on this technology, improvements in its function and use have occurred with the additional application of artificial intelligence and machine learning, allowing the images to independently accommodate to changes in the visualised anatomy. Corresponding development of navigation systems, allowing for the tracking of endovascular tools within these images by means of either fibre optics or electromagnetic field generators, are looking to improve the accuracy of the procedures while reducing the need for radiation and contrast agents. These tools are making a dramatic change in our ability to perform complex endovascular procedures, and are the future gold standard. Ultimately, these will allow procedures to occur more quickly and more safely.This study investigated whether androstadienone (AND) influences women's emotional perception of potential mates and rivals in a manner that promotes women's reproductive success. Sixty participants (29 in the fertile phase and 31 in the luteal phase) rated their perception of happiness, sadness, anger and sexual arousal from male and female neutral faces during exposure to AND or control solution on two consecutive days. The results showed that AND led women to perceive neutral female faces as unhappier, regardless of their menstrual cycle phase. In addition, AND led women in the fertile phase (i.e., periovulatory phase) to perceive more anger from neutral female faces. Further, no AND-effects were found on the emotional perception of male faces, nor were there perceptions of the sadness or sexual arousal in female faces. These findings may suggest that AND influences women's cognitive processing that can benefit women from staying away from potential threats or preparing to reduce the costs of intrasexual competition.The biological mechanisms linking diet-related obesity and autism-related behaviors remain unclear. We aimed to characterize these interactions, focusing on gut microbiota, 5-hydroxytryptamine (5-HT) levels, and autistic behaviors in an animal model for autism; a high-fat diet (HFD) BTBR T + Itpr3tf/J (BTBR) mouse. In this model, we also examined the medication effects of metformin (Met) which is known to ameliorate several symptoms of autism spectrum disorder (ASD). Therefore, we hypothesized that HFD exacerbates BTBR autistic symptoms, which can be alleviated by Met, and the effects are associated with serotonin and the microbiota. As expected, compared with mice fed a normal diet, ten-week HFD-fed mice showed increased body weight, adiposity, and glucose levels. HFD consumption markedly aggravated repetitive behaviors in the self-grooming test. Met reduced HFD-induced hyperactivity. Notably, HFD intervention rescued sociability in the three-chamber sociability test. Furthermore, HFD stimulated tryptophan production, which was inhibited by Met. In contrast, 5-HT levels were lower in the gut and higher in the cortex in the HFD group. Moreover, Met suppressed inflammation in the hippocampus of HFD-fed mice by significantly downregulating the expression of pro-inflammatory cytokines (NF-κB, IL-17A, and IL-6). HFD increased the Firmicutes/Bacteroidetes ratio, and Met supplementation decreased richness while increasing bacterial diversity. We found that the abundance of gut microbiota (Lachnoclostridium, Anaerotruncus, Mucispirillum, and Lactococcus) was correlated with behavior scores and 5-HT levels. Overall, HFD consumption improved sociality in BTBR mice, which was related to the modulation of 5-HT levels and the composition of the microbiota. Met did not show any significant positive effects on the autism phenotype associated with HFD.
γδ T cells were reported to play a key role in ischemic stroke. The integrity of the blood-brain barrier (BBB) directly affects the prognosis of ischemic stroke. This study aimed to determine whether γδ T cells aggravate BBB injury and determine the outcome of ischemic stroke.

Oxygen-glucosedeprivation (OGD) and middle cerebral artery occlusion (MCAO) were used as ischemic stroke models in vitro and in vivo. Flow cytometry was used to evaluate the intracranial infiltration of γδ T cells. RT-qPCR was used to evaluatethe mRNA levels of cytokines and γδ T cell markers. ELISA was used to test the levels of cytokines. Immunofluorescence, TEER and western blotting were used to measure BBB injury.

In this study, we found that a large number of γδ T cells infiltrated the ischemic penumbra 24h after MCAO. Knockout of γδ T cells improved the motor function injury induced by MCAO and significantly reduced the volume of cerebral infarction and blood-brain barrier injury. IL-17A neutralization could rescue the BBB injury induced by γδ T cells both in vitro and in vivo.

Peripheral γδ T cells immediately infiltrated into the lesion site after ischemic stroke and aggravated BBB injury by releasing IL-17A, which might be a potential therapeutic target for ischemic stroke.
