The possibility of a true 'rhythm' control strategy with catheter ablation has re-opened the debate on rate vs. rhythm control and the subsequent impact on stroke risk. Some observation studies suggest that successful AF catheter ablation and maintenance of sinus rhythm are associated with a decrease in stroke risk, while the CABANA trial had demonstrated no apparent reduction. Other observational studies have demonstrated increased stroke risk when oral anticoagulation (OAC) is discontinued after catheter ablation. When and in whom OAC can be discontinued after ablation will need to be determined in properly conducted randomized control trials. In this review article, we discuss our current understanding of the interactions between AF, stroke, and anticoagulation following catheter ablation. Specifically, we discuss the evidence for the long-term anticoagulation following successful catheter ablation, the potential for OAC discontinuation with restoration of sinus rhythm, and novel approaches to anticoagulation management post-ablation.

Quadricuspid aortic valve (QAV) is a rare abnormality, which may cause aortic regurgitation (AR) requiring surgical intervention in some patients. The characteristics associated with aortic valve functional degeneration in patients with QAV are still unknown. The aim of this study is to describe QAV prevalence, characterize the disease by multimodality imaging, evaluate predictors of severe AR, and assess mid-term prognosis.

Retrospective search in imaging exams database of one tertiary centre, for patients diagnosed with QAV between January 2007 and September 2019. QAV was characterized by cardiac computed tomography, transthoracic/transoesophageal echocardiography, and cardiac magnetic resonance. A total of 160 004 exams were reviewed and eight patients with QAV were identified (50% men, mean age 53.5 ± 10.7 years). The prevalence of QAV was 0.005%. During a median follow-up of 52 months (interquartile range 16-88), there were no deaths. Seven patients (88%) had pure AR (three severe, one moderate, and tment strategy.

Venous thromboembolism (VTE) is a potentially fatal complication of SARS-CoV-2 infection and thromboprophylaxis should be balanced against risk of bleeding. This study aimed to examine risks of VTE and major bleeding in hospitalized and community-managed SARS-CoV-2 patients compared with control populations.

Using nationwide population-based registries, 30-day risks of VTE and major bleeding in SARS-CoV-2 positive patients were compared with those of SARS-CoV-2 test-negative patients and with an external cohort of influenza patients. Medical records of all COVID-19 patients at six departments of infectious diseases in Denmark were reviewed in detail.

The overall 30-day risk of VTE was 0.4% (40/9,460) among SARS-CoV-2 patients (16% hospitalized), 0.3% (649/226,510) among SARS-CoV-2 negative subjects (12% hospitalized), and 1.0% (158/16,281) among influenza patients (59% hospitalized). VTE risks were higher and comparable in hospitalized SARS-CoV-2 positive (1.5%), SARS-CoV-2 negative (1.8%), and influenzients, but mirrored VTE risk in the intensive care setting.

Severe blepharoptosis with poor LF has traditionally been managed with exogenous frontalis suspension but complications such as lagophthalmos, infection, rejection were often reported.

The function-preserving frontalis orbicularis oculi muscle (FOOM) flap was designed to correct severe blepharoptosis with poor levator function (LF). With preservation of the OOM function, the long-term surgical outcome of the technique was assessed.

This retrospective study included only adult patients with severe blepharoptosis and poor LF, all of whom had their surgery performed by the senior surgeon, Lai CS, over a 6-year period. Clinical assessment of LF, palpebral fissure height (PFH), marginal reflex distance 1 (MRD1), duration of follow up, and postoperative complications were recorded.

34 patients and 59 eyelids were recorded during a mean follow-up period of 17.7 months. Postoperative evaluation yielded improvements of an average PFH gain of 5.62 ± 1.61mm (p < 0.001) as well as MRD1 and PFH increase by an average of 4.03 ± 0.82mm (p < 0.001) and 8.94 ± 0.81mm (p < 0.001), respectively. All patients demonstrated normalization of orbicularis function as no lagophthalmos was observed at the 8-month postoperative follow up. Recurrence of ptosis were recorded in four eyelids (6.78%). Revisions were performed in two eyelids (3.39%). No infection or granuloma was noted.

The function-preserving FOOM flap is a useful vector for frontalis suspension. Not only does it effectively address lagophthalmos as well as other complications, but it provides aesthetically pleasing outcomes in patients with severe blepharoptosis and poor LF.

Penile inversion vaginoplasty (PIV) has become the most commonly performed genital surgery for transfeminine patients. However, patients undergoing this procedure may still require revisions to achieve a satisfactory result.

The authors report on the utilization of autologous fat grafting to the labia majora to improve results after PIV and complications that may predict the need for grafting.

A retrospective chart review was conducted of a single surgeon's patients who underwent PIV between July 2014 and December 2019. Demographic information, operative information, and postoperative outcomes were abstracted from the health records. Wilcoxon rank sum tests and chi-squared test were employed for continuous variables and categorical, respectively.

A total of 182 transfeminine and gender-diverse patients underwent PIV, with 6 patients (3.3%) eventually undergoing labial fat grafting. The most common indication for labial fat grafting was flattened labia majora (83%). All fat grafting procedures were performed concurrently with other revisions of the vaginoplasty. There were no demographic or medical history differences detected between the fat grafting and non-fat grafting groups. Patients who underwent labial fat grafting were more likely to suffer from introital stenosis (33% vs 6%, P = 0.007) and prolonged granulation tissue greater than 6 weeks after initial vaginoplasty (83% vs 32%; P = 0.01).

Labial fat grafting is a safe and effective method to address defects in the labia majora after PIV. Prolonged granulation tissue and introital stenosis may predict the need for labial fat grafting, possibly due to increased scarring and contracture at the surgical site.

Infectious bronchitis virus (IBV) causes significant losses in the poultry industry throughout the world. Here we characterize the lesions of infectious bronchitis (IB), IBV prevalence and identify the circulating strains in small flocks in California. Backyard chickens (BYCs) submitted to the Davis (Northern California; NorCal) and San Bernardino (Southern California; SoCal) branches of the California Animal Health and Food Safety Laboratory System from January through March 2019 were included in the study. Trachea, kidney, and cecal tonsils were collected for qRT-PCR, histology, immunohistochemistry (IHC) and sequence analysis. A total of 50 chickens out of 169 submissions tested positive for IBV by qRT-PCR. Of these, 16% (20/123) were from NorCal and 65% (30/46) from SoCal laboratory. The cecal tonsil was the most frequently positive tissue by qRT-PCR and IHC. Lymphoplasmacytic tracheitis was the most frequent histopathologic finding in 24 of 39 birds while the kidney showed interstitial nephritis, tubular necrosis, tubular dilation and/or gout in 14 of 43 chickens. Infectious bronchitis virus played a primary role or a synergistic effect in the mortality of chickens succumbed by other infectious diseases. The sequences of IBV detected in 22 birds were analyzed and 14 strains were most similar to CA1737. One strain each matched Conn46, Cal99, and ArkDPI, and the remaining five did not have a substantial match to any available reference strains. The findings in this study indicate that small flocks can be reservoirs of IBV and might facilitate evolution of new variants as well as reversion of attenuated strains to virulence.Nitric oxide (NO) is an essential signaling molecule with a number of biological functions and holds great promise in biomedical applications. However, NO delivery technologies have been complicated due to the inherent properties of NO which include short half-life and limited transport distance in human tissues. In addition, the biofunctionality of NO is strongly dependent on its concentrations and locations where it is delivered. To achieve controlled NO delivery, many studies have focused on encapsulating NO donors into macromolecular scaffolds or using catalysts to realize in situ NO generation from NO prodrugs. Successful applications have been shown, however NO donor-loaded platforms experience the limitation of finite NO storage capacity. The present study reports the synthesis of a catalyst, copper-doped zeolitic imidazolate framework ZIF-8 (Cu2+/ZIF-8), that is designed to generate NO from naturally occurring endogenous NO donors. By tuning the copper doping percentages, we achieved controlled NO generation from S-nitrosoglutathione (GSNO) and S-nitrosocysteine (CysNO). Cu2+/ZIF-8 particles retained their catalytic potency after 5 NO generation cycles and we showed that our copper-doped ZIF-8 catalyst produced a 10-fold increased amount of NO compared with previous reports. As a proof-of-concept study, we demonstrated the ability of copper-doped ZIF-8 to disperse bacterial biofilms in the presence of GSNO.Self-healing hydrogels have emerged as promising biomaterials in regenerative medicine applications. However, an ongoing challenge is to create hydrogels that combine rapid self-healing with high mechanical strength to make them applicable to a wider range of organs/tissues. Incorporating nanoparticles within hydrogels is a popular strategy to improve the mechanical properties as well as to provide additional functionalities such as stimuli responsiveness or controlled drug delivery, further optimizing their use. In this context, mesoporous silica nanoparticles (MSNs) are promising candidates as they are bioactive, improve mechanical properties, and can controllably release various types of cargo. While commonly nanoparticles are added to hydrogels as filler component, in the current study we developed thiol surface-functionalized MSNs capable of acting as chemical crosslinkers with a known hydrophilic polymer, polyethylene glycol (PEG), through dynamic thiol-disulfide covalent interactions. Due to these dynamic exchange reactions, mechanically strong nanocomposites with a storage modulus of up to 32 ± 5 kPa compared to 1.
