.Aeromonas salmonicida is a gram-negative bacterium that is the causative agent of furunculosis. An A. salmonicida strain was isolated from diseased turbot (Scophthalmus maximus) with the sign of furunculosis from North China. Based on vapA gene, the strain was further classified as A. salmonicida subsp. masoucida RZ6S-1. Culturing RZ6S-1 strain at high temperature (28°C) obtained the virulence attenuated strain RZ6S. Genome sequence comparison between the two strains revealed the loss of the type IV secretion system (T4SS) and type III secretion system (T3SS) from the native plasmid pAsmB-1 and pAsmC-1 of wild-type strain RZ6S-1, respectively. Further study demonstrated that the wild-type strain RZ6S-1, but not its derivative mutant RZ6S, can stimulate apoptosis. Elevated protein level of cleaved caspase-3 was detected from epithelioma papulosum cyprinid (EPC) cells infected with wild-type strain RZ6S-1 as compared with that infected with RZ6S strain. Meanwhile, the invasion of the mutant strain RZ6S was about 17-fold higher than the wild-type strain RZ6S-1, suggesting that some protein(s) from A. salmonicida subsp. masoucida RZ6S-1 suppress its invasion. The RZ6S mutant strain was attenuated, since its LD50 is over 10,000 times higher compared to the wild-type strain as revealed in the turbot infection model.

Permanent His bundle pacing (p-HBP) could be an alternative for traditional cardiac resynchronization therapy (CRT), but an important limitation is that p-HBP cannot always correct the left bundle branch block (LBBB). The purpose of this article is to assess electrocardiographic patterns of LBBB that can predict electrocardiographic response (QRS narrowing) to His bundle pacing.

We designed a prospective descriptive study of patients with LBBB and CRT indication proposed for CRT by p-HBP. We analyzed the correlation between the different electrocardiographic patterns and the correction of conduction disturbance (LBBB).

We included 70 patients. Pacing at the location where His bundle electrogram was recorded narrowed the QRS in 81.4% (n=57). Basically, we identified two electrocardiographic patterns in lead V1 QS or rS. The QS pattern was a sensitivity of 56%, a specificity of 84.6%, and a positive predictive value (PPV) of 94.1% to predict the correction of the LBBB (area under the curve [AUC] = .70). In patients with rS pattern, a ratio between the descending and the ascending S wave component duration ≥0.64 was a very good predictor of the correction of the LBBB (AUC = .968); with a value ≥0.64, the sensitivity, specificity, and PPV was 92%, 100%, and 100%, respectively.

In patients with LBBB and CRT indication, the QS pattern in lead V1 predicts the correction of the QRS with HBP. In the case of rS pattern in lead V1, the ratio descending/ascending S wave component duration has a strong correlation with the LBBB correction.

The impact of sex on the outcomes after coronary artery bypass grafting (CABG) is controversial. The majority of CABG studies are retrospectively collected clinical or registry data, women comprise only a minority, and the reported findings represent the male predominated cohort. This individual patient meta-analysis is aimed at evaluating sex-related differences in outcomes after CABG using high quality data from randomized controlled trials (RCTs).

A systematic literature search will be performed to identify all CABG RCTs (minimum follow-up 5 years). Detailed specification for the minimum deidentified patient records’ data requirements will be provided to RCT primary contact to request their deidentified data for pooling. The pooled analysis will follow the prospective register of systematic reviews (PROSPERO) and the preferred reporting items for systematic reviews and meta-analyses for individual patient data systematic reviews (PRISMA-IPD) recommendations and will compare sex-related outcomes after CABG. The main hypothesis is that outcomes after CABG are worse in women than in men. We will also test whether treatment effects for off-pump and the use of multiple arterial grafts are present within each sex, and also, whether there are differential treatment effects between sexes. The primary endpoint will be a composite of all-cause mortality, myocardial infarction, stroke, and repeat revascularization at long-term follow up.

While it has evolved since its first description, one area of improvement continues to be its implementation. With advancements in cannulation techniques, in recent years, there has been a plethora of new cannulas that has been introduced in the market. For urgent venous-venous cannulation, the right internal jugular vein along with either femoral veins remain the most utilized strategy due to minimal need for imaging support. This allows for safe bedside cannulation. However, as the number of days of ECMO support continue to increase, transitioning to a cannulation strategy that is easier to ambulate with and more comfortable is preferred. Therefore, we describe a method for transitioning from right jugular-femoral cannulation to left subclavian placement of the Crescent Dual-Lumen catheter without interrupting ECMO support.
