To examine the incidence and risk factors for de novo atrial fibrillation (AF) after allogeneic hematopoietic cell transplantation (HCT) and to describe the impact of AF on HCT-related outcomes.

A retrospective cohort study design was used to examine AF and associated outcomes in 487 patients who underwent allogeneic HCT from 2014 to 2016 and to characterize patient- and HCT-related risk factors. A nested case-control study design was used to describe the association between pre-HCT echocardiographic measures and future AF events.

The median age at HCT was 52.4 years (18.1-78.6); the median time to AF was 117.5 days (4.0-1,405.0). The 5-year cumulative incidence of AF was 10.6%. Older (≥ 50 years) age (hazard ratio [HR], 2.76; 95% CI, 1.37 to 5.58), HLA-unrelated donor (HR, 2.20; 95% CI, 1.18 to 4.12), dyslipidemia (HR, 2.40; 95% CI, 1.23 to 4.68), and pre-HCT prolonged QTc interval (HR, 2.55; 95% CI, 1.38 to 4.72) were independent risk factors for AF. Despite having comparable left ventricular systolict demographics, pre-HCT cardiac parameters, HCT-related exposures, and risk of AF, setting the stage for targeted prevention strategies during and after HCT.We previously reported that the BTB domain-containing protein Clt1 regulates melanin and toxin synthesis, conidiation, and pathogenicity in Curvularia lunata, but the interacting proteins and regulative mechanism of Clt1 are unclear. In this research, we identified two proteins, which respectively correspond to xylanase (Clxyn24) and acetyl xylan esterase (Claxe43) from C. lunata were regulated by Clt1. Yeast two-hybrid (Y2H), and bimolecular fluorescence complementation assays were conducted to verify the interaction of Clt1 with full-length Clxyn24 and Claxe43. Furthermore, the Y2H assay revealed that Clt1 physically interacted with Clxyn24 and Claxe43 through its BTB domain to degrade xylan which was used as a carbon source for C. lunata growth. The utilization of xylan provides acetyl-CoA for the synthesis of melanin and toxin, as well as energy and other intermediate metabolites for conidiation. Furthermore, transcriptome analysis revealed that PKS18 and its 13 flanking genes are found clustered in a region spanning 57.89 kb on scaffold 9 of the C. lunata CX-3 genome were down-regulated in toxin production deficient mutant T806, and this cluster is possibly responsible for toxin biosynthesis of C. lunata.
Pulmonary vein isolation (PVI) represents the cornerstone in atrial fibrillation ablation. Cryoballoon and laserballoon catheters have emerged as promising devices but lack randomized comparisons. Therefore, we sought to compare efficacy and safety comparing both balloons in patients with persistent and paroxysmal atrial fibrillation (AF).

Symptomatic AF patients (n=200) were prospectively randomized (11) to receive either cryoballoon or laserballoon PVI (cryoballoon n=100 50 paroxysmal atrial fibrillation + 50 persistent AF versus laserballoon n=100 50 paroxysmal atrial fibrillation + 50 persistent AF). All antiarrhythmic drugs were stopped after ablation. Follow-up included 3-day Holter-ECG recordings and office visits at 3, 6, and 12 months. SB-743921 Kinesin inhibitor Primary efficacy end point was defined as freedom from atrial tachyarrhythmia between 90 and 365 days after a single ablation. Secondary end points included procedural parameters and periprocedural complications.

Patient baseline parameters were not different betated with significantly shorter procedure but not fluoroscopy time.
Both balloon technologies represent highly effective and safe tools for PVI resulting in similar favorable rhythm outcome after 12 months. Use of the cryoballoon is associated with significantly shorter procedure but not fluoroscopy time.
Pulsed field ablation (PFA) is a nonthermal energy with potential safety advantages over radiofrequency ablation. This study investigated a novel PFA system-a circular multielectrode catheter (PFA lasso) and a multichannel generator designed to work with Carto 3 mapping system.

A 7.5F bidirectional circular catheter with 10 electrodes and variable expansion was designed for PFA (biphasic, 1800 Volts). This study included a total of 16 swine used to investigate the following 3 experimental aims Aim 1 examined the feasibility to create a right atrial ablation line of block from the superior vena cava to the inferior vena cava. Aim 2 examined the effect of PFA on lesion maturation including durability after a 30-day survival period. Aim 3 examined the effect of high-intensity PFA (10 applications) on esophageal and phrenic nerve tissue in comparison to normal intensity radiofrequency ablation (1-2 applications). Histopathologic analysis of all cardiac, esophageal, and phrenic nerve tissue was performed.

Acctrode circular catheter and multichannel generator produced durable atrial lesions with lower vulnerability to esophageal or phrenic nerve damage.
To prospectively evaluate the effectiveness of risk-adapted preemptive tocilizumab (PT) administration in preventing severe cytokine release syndrome (CRS) after CTL019, a CD19 chimeric antigen receptor T-cell therapy.

Children and young adults with CD19-positive relapsed or refractory B-cell acute lymphoblastic leukemia were assigned to high- (≥ 40%) or low- (< 40%) tumor burden cohorts (HTBC or LTBC) based on a bone marrow aspirate or biopsy before infusion. HTBC patients received a single dose of tocilizumab (8-12 mg/kg) after development of high, persistent fevers. LTBC patients received standard CRS management. The primary end point was the frequency of grade 4 CRS (Penn scale), with an observed rate of ≤ 5 of 15 patients in the HTBC pre-defined as clinically meaningful. In post hoc analyses, the HTBC was compared with a historical cohort of high-tumor burden patients from the initial phase I CTL019 trial.

The primary end point was met. Seventy patients were infused with CTL019, 15 in the HTBC and 55 in the LTBC.
