Abstract
Abstract
Background
Andersen-Tawil type 1 (ATS1) is associated with loss-of-function mutations in the inward rectifier potassium channel Kir2.1, which controls cardiac excitability and impulse conduction. Phosphatidylinositol-4,5-bisphosphate (PIP2) acts as an essential cofactor regulating the opening of Kir2.1 channels. Fifty percent of reported ATS1 mutations affect Kir2.1-PIP2 interactions, leading to ECG defects, ventricular arrhythmias and sudden cardiac death (SCD) by mechanisms that are poorly understood.
Purpose
To test the hypothesis that the degree of arrhythmogenic severity of ATS1 mutations disrupting PIP2-Kir2.1 binding may be predicted by the level of polarization of the mutant Kir2.1 channel pore.
Methods
We first used a statistical mean value approach to classify the 40 known arrhythmogenic ATS1 mutations impacting Kir2.1-PIP2 interaction (N=260 individuals) according to arrhythmogenic severity, ranging from SCD through ventricular bigeminy and QT prolongation. We then generated 3D in-silico atomic models of the wildtype channel and the 10 mutant channels with the most severe arrhythmic phenotype to assess the mechanism of the structural defects associated with Kir2.1-PIP2 disruption.
Results
Our cardiac lethality scoring stratifying Kir2.1 mutations according to arrhythmogenic severity was validated by three additional biostatical quantitative measures. On in-silico modelling, wildtype Kir2.1 channels without PIP2 binding had transmembrane and cytoplasmic pore radius of 1.5 and 3 Å, respectively. Kir2.1-PIP2 interactions increased transmembrane and cytoplasmic pore radius to 3 and 6 Å, respectively. All 10 Kir2.1 mutations had similar transmembrane and cytoplasmic pore radius of ∼1.0 and ∼3.0 Å, respectively. The most severe mutations yielded pore channels with highly polarized electrostatic forces. Remarkably, simulations showed a descending electrostatic pattern at the transmembrane region of PIP2 binding, where the more severe the mutation, the more positive that region was. Structural changes produced by mutations correlated with cardiac severity (R2=0.51; p<0.005) in that the most drastically altered protein structure correlated with the most severe arrhythmic phenotype.
Conclusions
Computer simulations of mutant Kir2.1 channel structure from the most arrhythmogenic to the least arrhythmogenic predict a gradual decrease in polarization of electrostatic forces along the Kir2.1 channel pore. The results reveal a novel mechanistic stratification of arrhythmogenic severity of ATS1 mutant Kir2.1 channel-PIP2 interactions and open new pathways for developing more personalized ATS1 patient therapies.

Background
Concurrent training (i.e. a combination of aerobic and resistance exercise in the same session) is emerging as a time-efficient exercise strategy for improving cardiorespiratory fitness and controlling body composition parameters.
Purpose
The purpose of this study was to determine the effectiveness of a concurrent exercise program on cardiorespiratory fitness and body composition in adults with schizophrenia (SP).
Methods
Participants (n=98, 20.4% women, 41.4±10.1 yr old) with SP were randomly assigned into an attention control group (usual care) or a supervised exercise group (concurrent training, 3 days/week). All variables were assessed pre- and post-intervention (20 weeks). For the assessment of cardiorespiratory fitness, a peak cardiopulmonary exercise test on a cycle ergometer and the Modified Shuttle Walk Test (MSWT) were used.
Results
Following the intervention, in the control group, there was a significant (P <0.05) increased in body mass (Δ = 2.54%), body mass index, BMI (Δ = 2.82%), waist circumference (Δ = 2.70%) and a decreased in MSWT (Δ = - 7.54%). However, in the exercise group, there was a significant (P<0.001) increased in first ventilatory threshold, VT1 (Δ = 28.69%), peak oxygen uptake, V̇O2peak (L∙min-1) (Δ = 19.58%), V̇O2peak (mL∙kg.1∙min-1) (Δ = 21.52%) and MSWT-distance (Δ = 11.43%), with no significant changes in body composition (P>0.05). When both groups were compared, body mass, and BMI was significantly (P<0.05) more reduced, and VT1, V̇O2peak, and MSWT more increased in the exercise group.
Conclusion
A supervised concurrent exercise program in people with SP helps to maintain body composition values and leads to improvements in cardiorespiratory fitness levels. Exercise should be considered as a co-adjuvant program in the treatment of population with SP.

Abstract
Woodwind tonehole's linear behavior is characterized by two complex quantities: the series and shunt acoustic impedances. A method to determine experimentally these two quantities is presented for the case of open toneholes. It is based on two input impedance measurements. The method can be applied to clarinet-like instruments, and can be used for undercut toneholes as well as toneholes with pads above their output, under the condition that a symmetry axis exists. The robustness of the method proposed is explored numerically through the simulation of the experiment when considering geometrical and measurement uncertainties. Experimental results confirm the relevance of the method proposed to estimate the shunt impedance. Even the effect of small changes in the hole's geometry, such as those induced by undercutting, are characterized experimentally. The main effect of undercutting is shown to be a decrease in the tonehole's acoustic mass, in agreement with theoretical considerations based on the shape of the tonehole. Investigation on the effects of pads will be studied in a further work. Experimental results also reveal that losses in toneholes are significantly higher than those predicted by the theory. Therefore, the method is suitable for the experimental determination of the shunt impedance, but it is not convenient for the characterization of the series impedance.

Abstract
Background:Patients with rheumatoid arthritis (RA) have an altered gut microbiota (dysbiosis) (1-3). This microbiota interacts with intestinal epithelium which can lead to an increased intestinal permeability, responsible for the passage of antigens and inflammatory molecules, and can therefore promote systemic inflammation. Gut microbiota tends to normalize with disease control (2), suggesting that systemic inflammation may directly influence the composition of microbiota and the gut barrier. It was shown in many inflammatory diseases that intestinal permeability is impaired, but to date there is very little data in RA.Objectives:In the present study, we evaluate the intestinal permeability in RA patients by analyzing tight junctions in colonic biopsies and serum markers.Methods:Colonic biopsies from 20 RA patients who underwent coloscopy for screening with normal histology were compared with those from 20 age and sex matched controls. ZO-1, occludin and claudin 2 junction proteins were evaluated by immunohistochemistry. The staining intensity was assessed by two blinded independent readers. The serum concentrations of LPS-binding protein (LBP), CD14s and zonulin were evaluated by ELISA in 25 patients naive of DMARDs, 41 patients before and after introduction of a DMARDs and 21 controls. Elevated zonulin in serum indicates an increase in intestinal permeability while LBP and CD14s indicate bacterial translocation.Results:ZO-1 expression was significantly lower in biopsies from patients with RA than controls (mean score ± SD of 1.6 ± 0.56 vs 2.0 ± 0.43; p = 0.01). Age, sex, disease duration and immunological status did not significantly influence the expression of colonic junction proteins. LBP and CD14s were higher in serum from RA patients naive of DMARDs than controls (p = 0.002 and p = 0.003). LBP, CD14s and zonulin levels significantly correlated with DAS28 (r = 0.61, p = 0.005; r = 0.51, p = 0.030 and r = 0.46, p = 0.049, respectively). After treatment, unlike non-responders, LBP and CD14s were significantly reduced in DMARD responders and variations in LBP and CD14s significantly correlated with changes in DAS28 (r = 0.46, p = 0.002 and r = 0, 33 and p = 0.030, respectively).Conclusion:This work is one of the first to explore intestinal permeability in RA and to show altered tight junction in colonic tissue from RA. This increased intestinal permeability appears to be related to the systemic inflammation. Improving the gut microbiota through food or probiotics could enhance the effect of treatments by limiting this amplification loop of inflammation.References:[1]Horta-Baas G, Romero-Figueroa MDS, Montiel-Jarquin AJ, Pizano-Zarate ML, Garcia-Mena J, Ramirez-Duran N.

Abstract
One of the parameters that has the most influence on invitro embryo production programs is the number of oocytes obtained in each follicular aspiration session (ovum pickup; OPU). A significant impact of the breed of the donor on this parameter has been reported. The objective of this work was to compare the parameters of an invitro embryo production program of cows of different breeds in Paraguay. A total of 4811 OPU sessions were performed between 2016 and 2019 in cows classified according to breed and type. Beef-type breeds: Nelore (Bos indicus): n=1569; Aberdeen Angus (Bos taurus): n=1276; and Brangus (Cross): n=182 OPU, and Gyr (Bos indicus): n=1086; dairy breeds: Holstein (Bos taurus): n=401, and Girolando (Cross): n=297. The oocytes were aspirated and transported to the same laboratory located in Asunción, Paraguay. The invitro embryo production protocol was similar in all types. Bull semen tested for IVF was used. The number of oocytes, percentage viability, and percentage embryo production were evaluated. Additionally, the mean and standard deviation of the variables were calculated to show the efficiency of the processes, according to the production aptitude of the donors (meat or milk) and the breed type (Bos indicus, Bos taurus, or crosses). Continuous data were analysed with ANOVA and Tukey’s post hoc comparisons. Categorical data were analysed using Chi-squared at a significance level of 0.05. In this work, the production aptitude had no significant effect over the studied variables. However, some significant differences were found considering the breed type of the oocyte donor cow, as shown in Table 1. When crosses with the pure breeds are compared with their crosses, we found that Brangus produced more pregnancies and a greater number of oocytes/OPU compared with Angus (P<0.05). When the same comparison was made between Girolando and Holstein, no significant differences were found. The results show that Bos indicus breeds and their crosses have a greater capacity to produce more oocytes and embryos and that Bos indicus and crossbreeds were more efficient in producing pregnancies (2-fold) per OPU session than Bos taurus breeds. Additionally, crossing with meat indicus breeds generates better quality embryos and increases efficiency in the system of embryo production.

Abstract
Abstract
Introduction
Anthracycline-induced cardiotoxicity (AIC) is a serious adverse effect occurring in a significant proportion of patients. Irreversible mitochondrial damage is a central mechanism of AIC. Despite many efforts, there is a lack of therapies able to prevent AIC. Remote ischemic preconditioning (RIPC) could be a promising therapy to prevent AIC due to the scheduled application of chemotherapy in cancer patients.
Purpose
To evaluate the cardioprotective efficacy of RIPC in large animal model of AIC.
Methods
Large-White pigs (n=20) underwent a validated protocol of AIC consisting on five intracoronary doxorubicin injections (0.45 mg/kg), on weeks 0, 2, 4, 6, 8 of the study. Pigs were randomized before the initiation of the study to remote ischemic pre-conditioning (RIPC, 3 cycles of 5 min lower limb ischemia followed by 5 min reperfusion) or sham procedure immediately before doxorubicin injections. An additional group of 10 pigs without any exposure to doxorubicin was carried out as controls. Pigs underwent a comprehensive serial cardiac magnetic resonance (CMR) exam baseline, and on weeks 6, 8, 12, and 16. After 16-week CMR, pigs were sacrificed and tissue samples collected. A second group of 10 pigs (randomized 1:1 for RIPC) underwent the same protocol but were sacrificed 2 weeks after the third doxorubicin dose for early evaluation of tissue changes. Primary endpoint of the study was CMR-based left ventricular ejection fraction on week 16.
Results
Until week 6 (time of fourth doxorubicin injection), LVEF remained unchanged in both groups. From there on, a progressive decline in LVEF was observed. LVEF depression trajectory was blunted in RIPC animals. Compared to controls, pigs undergoing RIPC before each doxorubicin dose had a significantly higher LVEF at week 16: median (IQR) 45% (27–50%) vs 33% (19–47%) in RIPC and controls respectively, p=0.04. Improvement in LVEF was mainly due to a more preserved contractile function, as evidence by smaller LVESV, and better regional contractile function. After 3 doxorubicin doses, a time where global (LVEF) and regional contractile function was still unchanged, transmission electron microscopy (TEM) showed fragmented mitochondria with remodeled cristae only in control pigs. At the end of the 16 weeks, TEM evaluation in control pigs (as compared to RIPC pigs) showed overt cardiomyocyte's mitochondrial fragmentation with overt structural derangement. At this time, RIPC pigs had significantly less interstitial fibrosis on histology.
Conclusions
In a translatable large animal model of AIC, RIPC applied immediately before each doxorubicin cycle resulted in a preservation of cardiac contractility with significantly higher long-term LVEF and less cardiac fibrosis. RIPC prevented the deleterious effects of doxorubicin on mitochondria since early stages of AIC. RIPC is a promising intervention to be tested in clinical trials to prevent cardiotoxicity.

Abstract
Abstract
Introduction
Non-sustained ventricular tachycardias (NSVT) are observed frequently among ICD patients with left ventricular dysfunction (LVD).
Purpose
To analyze the relationship between episodes of NSVTs and monomorphic VTs (MVTs) that subsequently cause appropriate therapies.
Methods
416 ICD patients with LVD (LVEF <45%) followed for 41±27 months. ICD programming (detection and therapies) was standardized. NSVT was defined as any VT of ≥5 beats which did not met the detection criteria occurring within the first 6 months after ICD implant. We analyzed 2201 NSVTs (10+7 beats), which occurred in 250 of the 416 patients (Median=2; IQR=0–7). The mean cycle length (CL) of NSVT was 323±32 ms (adjusted per multiple episodes/patient, generalized estimating equation method (GEEM)).
Results
During the follow-up, 1441 MVT occurred in 183 patients. After showing a significant correlation between burden of NSVT and the occurrence of appropriate therapies due to MVT (C coefficient=0.68; p<0.001), we observed that subjects with >5 NSVT presented an excess of adjusted risk: HR=1.97 (95% CI=1.45–2.72); p<0.001. However, the adjusted mean CL of NSVTs was similar in patients with (322±34) vs. without MVT (324±26 ms); p=0.3.
Among patients who presented NSVTs and MVTs (n=145 subjects), we analyzed the relationship between the adjusted mean CL of the NSVTs (n=1288 episodes) and the CL of the first appropriate therapy due to MVT occurring subsequently. We found a significant and positive correlation between the two (r=0.88; p<0.001); the strongest correlation was observed in subjects with >5 NSVTs (r=0.97, n=52)). The robustness of such correlation was similar in individuals with ischemic (r=0.86; n=91) versus non-ischemic cardiomyopathy (r=0.90; n=54), and in primary (r=0.86; n=75) versus secondary prevention (r=0.90; n=70). The agreement between the CL of first MVT and the adjusted mean CL of NSVT episodes (GEEM) was determined according to the Bland-Altman Method. The difference between the two values was 2±8.3 ms, with only 7.6% (11/145) of patients in whom the difference between the two CL was outside the concordance limits. The agreement was greater, again, in individuals with >5 NSVTs. As shown in the Figure, in more than 95% of patients both values were within the interval of agreement (0.32±4 ms).
Conclusions
1-The burden of NSVTs occurring early after an ICD implant, but not their CL, is associated with a higher incidence of appropriate therapies due to MVT at follow-up.
2-The CL of the NSVTs and that of the first and subsequent MVTs is virtually the same in patients with higher NSVT burden. Therefore, it could be the same tachycardia, but with different duration.

Abstract
Aims
To evaluate the safety and feasibility of a transradial-access PCI program in CTO and its impact on angiographic and clinical results and in-hospital stay length.
Methods
Retrospective single-centre cohort-study including 237 consecutive patients undergoing CTO-PCI. From November 2018 onwards, a transradial-access program and all first-attempt CTO-PCI procedures were systematically performed via the radial artery. 47 patients included in the transradial-access CTO-PCI program were compared to a historical cohort of 190 CTO-PCI patients, employing transfemoral access mainly: n=150 (78.9%).
Results
Mean age was 66.9±11.4 and 199 (83.9%) patients were male, Table 1. Mean J-CTO score (2.5±1.1) was similar in both groups. Successful revascularization was achieved in 208 (87.8%) cases overall, without differences between both cohorts. No differences in periprocedural complications between both groups existed, but in-hospital complications were numerically lower in the transradial cohort (4.3% vs 13.7%, p=0.072). Mean hospital-stay was lower in the transradial-access group (0.89±1.4 vs 2.2±3.2 days, p<0,001). Same-day discharge was successfully accomplished in 56% of elective patients in the transradial-access program, Figure 1.
Conclusion
A transradial program for CTO-PCI is safe and effective in most CTO. Adoption of a transradial protocol for CTO-PCI allows same-day hospital discharge in over half of elective procedures and reduces in-hospital stay length.

Abstract
Abstract
Ventricular tachycardia (VT) substrate-based ablation has become a gold standard in patients with structural heart disease. Success of VT ablation is related with mortality reduction.
Late gadolinium enhancement cardiac magnetic resonance (LGE-CMR) is a powerful technique to assess substrate of VT. Myocardial fibrosis is electrically inert (Core) but it is surrounded by a ‘‘border-zone (BZ)’’ where normal cardiomyocytes intermingle with dense bundles of fibrosis. Slow impulse conduction in the BZ allows for the re-entry circuits leading to VT. Both the presence and extent of LGE have been associated with VT and SCD risk. LGE-CMR tissue characterization can be depicted as pixel signal intensity (PSI) maps and can guide VT ablation.
The aim of this study was to analyze possible VT recurrence predictors in a long term follow-up of patients that underwent VT ablation (endo and/or epicardial) related with LGE-CMR PSI maps.
We analyzed 234 consecutive patients (age: 63.2 ± 14 years, follow-up: 3.14 years ±1.8) undergoing VT ablation with scar-dechannelling technique at a single center from 2013 to 2018. 110 patients underwent a preprocedural LGE-CMR, and in 94 patients (85,5%) a CMR-aided ablation using the PSI maps was performed.
All LGE-CMR images were semi-automatically processed using a dedicated software. PSI-based algorithm was applied to characterize the hyperenhanced area as core or BZ, using fixed threshold of the maximum intensity. A LV 3D shell was obtained and were imported into the navigation system. In the PSI maps, heterogenous tissue channels were defined as a continuous corridor of BZ surrounded by scar core or an anatomic barrier that connects 2 areas of healthy tissue.
Results
Overall recurrence of VT was 41.8 %. There was ICD shock reduction, from 43,6% to a 28,2% (ICD shocks before ablation 2,23 ± 7,32, after: 1,10 ± 2,92).
Left ventricle mass predicted significantly VT recurrence (Mean 168,3 ± 53,3 vs 152,3 ± 46,4 g, HR 1,02 [1,01-1,02], p < 0.001). LGE distribuition was predictive of VT recurrence when a more than 40% of the interventricular septum was involved (62,5% vs 37,8%; HR 1,6 [1,01-1,02]; p = 0,044). No differences in recurrence were found among the patterns of LGE distribution (transmural/epicardial/subendocardial or peculiar segments localizations). The amount of BZ and the total amont of Core + BZ was related with VT recurrence (BZ 26,6 ± 13,9 vs 19,56 ± 9,69 g, HR 1,03 [1,01-1,06], p = 0,012; total Core + BZ 37,1 ± 18,2 vs 29,0 ± 16,3 g, HR 1,02 [1,00-1,04], p = 0,033). Finally VT recurrence was higher in patients with channels with transmural path (66,7% vs 31,4%, HR 3,25 [1,70-6,23], p < 0,001) or midmural channels (54,3% vs 27,6%, HR 2,49 [1,21–5,13], p = 0,013).
CMR-aided scar dechanneling is a helpful and feasible technique which could identify patients with high risk of VT recurrence. High left ventricular mass, septal LGE distribution, transmural and midmural heterogeneous tissue channels were predictive factors of post ablation VT recurrence.

OBJECTIVE To estimate the agreement between an expert and a non-expert examiner using the International Ovarian Tumor Analysis (IOTA) simple rules for classifying adnexal masses on real-time ultrasound and when using three-dimensional (3D) ultrasound volumes and digital clips. METHODS Forty-two non-consecutive women diagnosed as having an adnexal mass were evaluated by transvaginal power Doppler ultrasound as part of their diagnostic work-up. In each woman, examination was first performed by a non-expert examiner (a trainee) and immediately afterwards by an expert examiner. Both used the IOTA simple rules to describe the mass, blinded to each other's results. After finishing the examination, each examiner classified the mass as benign, malignant or inconclusive, according to the IOTA simple rules. Additionally, the expert recorded a short videoclip and acquired a static 3D volume of each mass, which were subsequently assessed by four trainees in obstetrics and gynecology with different levels of training, who also classified the mass as benign, malignant or inconclusive according to the IOTA simple rules. Agreement was assessed by calculating weighted and standard kappa index values with 95% CI and the percentage of agreement between observers. RESULTS Agreement between the observers who performed real-time ultrasound examination was good (weighted kappa = 0.76; 95% CI, 0.61-0.90; agreement = 78.6%). Agreement between trainees using videoclips plus 3D volumes was moderate (kappa values ranged from 0.45 to 0.58, depending on pair comparison). CONCLUSION Interobserver agreement of the IOTA simple rules for classifying adnexal masses as benign, malignant or inconclusive using real-time ultrasound, between an expert and a non-expert examiner, might be considered good. Agreement using a videoclip plus a 3D volume was moderate for trainees with different degrees of training.

Abstract
BACKGROUND AND PURPOSE Extensive white matter damage has been documented in patients with severe traumatic brain injury, yet how this damage evolves in the long term is not well understood. We used DTI to study white matter changes at 5 years after traumatic brain injury. MATERIALS AND METHODS There were 8 healthy control participants and 13 patients with severe traumatic brain injury who were enrolled in a prospective observational study, which included clinical assessment and brain MR imaging in the acute setting (< 6 weeks) and 2 years and 5 years after injury. Only subjects with mild to moderate disability or no disability at 1 year were included in this analysis. DTI parameters were measured in 20 different brain regions and were normalized to values obtained in an age-matched control group. RESULTS In the acute setting, fractional anisotropy was significantly lower in the genu and body of the corpus callosum and in the bilateral corona radiata in patients compared with control participants, whereas radial diffusivity was significantly (P < .05) higher in these tracts. At 2 years, fractional anisotropy in these tracts had further decreased and radial diffusivity had increased. No significant changes were detected between 2 and 5 years after injury. The baseline radial diffusivity and fractional anisotropy values in the anterior aspect of the brain stem, genu and body of the corpus callosum, and the right and left corona radiata were significantly (P < .05) associated with neurocognitive sequelae (including amnesia, aphasia, and dyspraxia) at year 5. CONCLUSIONS DTI changes in major white matter tracts persist up to 5 years after severe traumatic brain injury and are most pronounced in the corpus callosum and corona radiata. Limited structural change is noted in the interval between 2 and 5 years.
