Catheter ablation in adult congenital heart disease (ACHD) patients is a critical treatment strategy for complex arrhythmias including atrial fibrillation (AF) and atrial tachycardia (AT). In addition to vitamin K antagonists (VKAs), direct oral anticoagulants (DOACs) are increasingly used in this patient population.

The purpose of this study was to assess the safety of catheter ablation in ACHD patients on uninterrupted oral anticoagulation with VKA or DOAC, examining thromboembolic, bleeding, and vascular access complications.

Retrospective analysis of 234 ACHD patients with simple (n = 83), moderate (n = 66), or complex (n = 85) CHD (mean age 46 years) undergoing 368 ablation procedures on uninterrupted oral anticoagulation with VKA (45.4%) or DOAC (54.6%) was undertaken. Arrhythmias were AF in 97, right AT in 181, left AT in 65, or a combination of AF and AT in25.

No thromboembolic complications occurred. Major complications occurred in 4 patients (1.1%; 1 VKA, 3 DOAC), including retroperitoneal hs complications between patients on DOAC or VKA were found.

The etiology of atrial fibrillation (AF) is multifactorial and incompletely understood.

The purpose of this study was to evaluate the association between coronary artery disease (CAD) affecting atrial tissue and AF.

Patients from a single center with obstructive CAD during cardiac catheterization (January 1, 2007, through December 1, 2013) were included in a matched case-control analysis on the basis of the presence or absence of new-onset AF within 12 months of catheterization. Quantitative measurements of stenosis severity were performed for the sinoatrial nodal artery, atrioventricular (AV) nodal artery, and right intermediate atrial artery (RIAA) as well as the right coronary, left circumflex, and left anterior descending proximal to the takeoff for each atrial level artery. A multivariable logistic regression model identified factors associated with AF.

Of 1794 patients, 115 (6%) developed AF within 1 year of catheterization. The matched cohort included 110 patients with and 110 patients without AF within 12 months of catheterization. Higher odds of AF at 1 year were associated with increasing lesion stenosis severity in the RIAA (odds ratio [OR] 1.41 per 10% increase >50%; 95% confidence interval [CI] 1.01-1.97; P = .047) and AV nodal artery (OR 1.58 per 10% increase >50%; 95% CI 1.00-2.49; P= .050). Odds of AF diagnosis during the year after catheterization increased with the number of atrial arteries with >50% lesion (OR 1.53 for each additional artery; 95% CI 1.08-2.15; P = .015).

In patients with obstructive CAD, disease of the AV nodal artery and RIAA as well as a higher burden of CAD within all arteries supplying blood flow to the atrial myocardium were associated with higher odds of new-onset AF at 1 year.

Variation in lamin A/C results in a spectrum of clinical disease, including arrhythmias and cardiomyopathy. Benign variation is rare, and classification of LMNA missense variants via in silico prediction tools results in a high rate of variants of uncertain significance (VUSs).

The goal of this study was to use a machine learning (ML) approach for in silico prediction of LMNA pathogenic variation.

Genetic sequencing was performed on family members with conduction system disease, and patient cell lines were examined for LMNA expression. ABT-199 order In silico predictions of conservation and pathogenicity of published LMNA variants were visualized with uniform manifold approximation and projection. K-means clustering was used to identify variant groups with similarly projected scores, allowing the generation of statistically supported risk categories.

We discovered a novel LMNA variant (c.408C>Ap.Asp136Glu) segregating with conduction system disease in a multigeneration pedigree, which was reported as a VUS by a lial testing is unavailable.

In the largest avascular low-nutrient intervertebral disc, resident cells would utilize autophagy, a stress-response survival mechanism by self-digestion and recycling wastes. Our goal was to elucidate the involvement of autophagy in disc homeostasis through RNA interference of autophagy-related gene 5 (Atg5).

In vitro, small interfering RNAs (siRNAs) targeting autophagy-essential Atg5 were transfected into rat disc cells. Cell viability with levels of autophagy including Atg5 expression, apoptosis, and senescence was assessed under serum starvation and/or pro-inflammatory interleukin-1 beta (IL-1β) stimulation. In vivo, time-course autophagic flux was monitored following Alexa Fluor® 555-labeled Atg5-siRNA injection into rat tail discs. Furthermore, 24-h temporary static compression-induced disruption of Atg5 siRNA-injected discs was observed by radiography, histomorphology, and immunofluorescence.

In disc cells, three different Atg5 siRNAs consistently suppressed autophagy with Atg5 protein knockdown tg5-dependent autophagy-mediated anti-apoptosis and anti-senescence. Autophagy could be a molecular therapeutic target for degenerative disc disease.

Osteoarthritis (OA) started to be associated to shifted microbiota composition recently. This systematic review aims to elucidate if there is a common microbiota composition linked with OA between different studies.

We screened PubMed, Scopus, Web of Science and Cochrane databases up to July 26

2021 to identify original studies in which microbiome was assessed from OA individuals, both in human and laboratory animals' studies. Bacteria associated with OA were summarized to find common patterns between the studies.

We identified 37 original studies where the microbiota composition was assessed in OA subjects. We identified some bacteria (Clostridium, Streptococcus, Bacteroides and Firmicutes) that were reported to be upregulated in OA subjects, whereas Lactobacillus and Bifidobacterium longum were associated with improved OA outcomes. The heterogeneity of sampling and analysis methods, different taxonomical levels reported and the lack of healthy controls in several studies made it difficult to compare the studies and reach conclusions about a potential causal link.

The current study demonstrated that some bacteria were identified as regulators of OA. Future works following standardized methodologies with more proper controls are needed to elucidate our understanding of the role of the microbiota in OA pathogenesis and progress towards new treatments.

Spinal infection (SI) is a life-threatening condition and its treatment remains challenging. Recent studies have supported early and aggressive surgery, but mortality still reaches 5% to 10% and it remains unclear, if an aggressive surgical strategy also applies for severely sick patients.

The aim of this analysis was to generate an assessment score to predict mortality of SI in order to facilitate decision-making.

Retrospective Risk-Factor-Analysis.

Two hundred fifty-two patients were retrospectively analyzed.

Physiologic Measures, Functional Measures.

Diagnosis was based on clinical presentation, imaging findings and inflammatory markers. Factors associated with mortality were identified by multivariate analysis, weighted according to their relative risk ratio (RR) and included in the novel assessment score.

Eight parameters were included (1) BMI, (2) ASA score, (3) presence of sepsis, (4) age-adjusted Charlson Comorbidity Index, (5) presence and degree of renal failure, (6) presence of hepatopathy, (7) neurological deficits and (8) CRP levels at diagnosis. Each parameter was assigned a certain range of points, resulting in a maximum total score of 20. The mortality in spinal infection (MSI-20) score - indicating poorer status with higher values - was obtained for each patient and correlated with mortality.

A MSI-20 score of 11 or more points seems to identify the small group of patients being "too sick to undergo surgery," while early surgery can be recommended in the remainder (MSI-20 ≤10). Our results need to be confirmed in prospective studies, but may give guidance for indicating surgery even in rather sick and comorbid patients.

As science and technology have advanced, novel bone cements with numerous formulated ingredients have greatly evolved and been commercialized for vertebroplasty. Recently, viscosity has been a focus to achieve better clinical outcomes and fewer complications. Meanwhile, the experience in the treatment of mid (T7-9) to high (T4-6) thoracic vertebral compression fractures is limited.

The objective of this study was to identify the different outcomes between high-viscosity bone cement (HVBC) and low-viscosity bone cement (LVBC) used to repair mid (T7-9)- and high (T4-6)- thoracic vertebral compression fractures.

This study was a single-center, retrospective cohort study PATIENT SAMPLE A consecutive series of 107 patients with a total of 144 vertebrae was included.

The anterior vertebral height (AVH), middle vertebral height (MVH), posterior vertebral height (PVH), local kyphotic angle (KA), Cobb angle (CA), and other associated parameters were evaluated radiologically at several time points-preoperative,3, p=.024), and the use of HVBC was associated fewer cases with cement leakage (26 vs. 45, p=.002). Furthermore, there was no difference between the groups in the incidence of adjacent fracture. Both groups showed an improved VAS score at follow-up, with statistically greater improvement in the HVBC group (2.40±1.53 vs. 3.07±1.69, p=.014). Moreover, significantly fewer patients with a VAS score ≥ 3 were found in the HVBC group (22 vs. 39, p=.004) CONCLUSIONS HVBC and LVBC are safe and effective to treat mid-to-high level thoracic vertebral compression fractures. Compared with LVBC, HVBC shows less cement leakage, a greater injection volume, and better postoperative pain relief.

A justifiable sample size is essential at trial design stage. Generally this task is completed by forming the main research question into a statistical procedure and then implementing the published formulae or software packages. When these standard statistical formulae/software packages become unavailable for studies with complex statistical procedures, some statisticians choose to fill this gap by assuming an alternative simplified sample size calculation. Monte Carlo simulations can also be deployed, particularly for complex trials. However, it is still unclear on how to determine the appropriate approach under certain practical scenarios.

We adopted real clinical trials as examples and investigated on simplification and simulation-based sample size calculation approaches.

Compared to simplified sample size calculation, the simulation approach can better address the non-ignorable impact of baseline/follow-up outcome correlation on study power. For studies with multiple endpoints and multiple co-primary endpoints, the sample sizes calculated by simplification approach should be scrutinized.
