Abstract Aims Pulmonary vein isolation (PVI) is the treatment of choice in patients (pts) with symptomatic atrial fibrillation. Durable pulmonary veins isolation (PVI) seems to be associated with a lower risk of AF recurrence, but the predictor factors of persistent PVI are still uncertain. We aimed to determinate the predictor factors and the prognostic role of persistent pulmonary veins isolation in pts with arrhythmia recurrence necessitating a second ablation procedure. Methods and results Our Study included 102 pts (65.7% male, 65±8 years old, 75.5% persistent AF) with arrhythmia recurrence, whom underwent a Redo-PVI between October 2016 and Mars 2018. Patients were divided into two groups regarding the persistence of PVI. Group 1 included 20 pts with persistent PVI and Group 2 included 82 pts with reconnection of at least one PV. The clinical profile, ablation data and three months arrhythmia recurrence were analyzed. There were no statistical differences in terms of clinical profile between the two groups of pts (age; p=0.513, gender; p=0.299, BMI; p=0.077, diabetes mellitus; p=0.621, coronary artery disease; p=0.787; arterial hypertension; p=0.732; left ventricle ejection fraction; p=0.323 and left atrial diameter; p=0.5). Patients in group 1 presented more often with atrial tachycardia compared to group 2 Patients (30% versus 7.3%; p=0.014). Regarding the ablation data, there were no differences between the two groups in terms of procedure time (p=0.710) but the ablation time was longer in group 2 patients (29.1±13.7 versus 20.8±10.5 min. p=0.031). Low voltage areas (LVA) acquired by bipolar electroanatomical mapping were more often and diffuse in group 1 patients (70% versus 40.3%; p=0.050). The three months arrhythmia recurrence after Redo-Ablation was the same between the two groups (p=1.000). Conclusion The type of arrhythmia recurrence and low voltage areas are predictor factors of persistent pulmonary veins isolation in patients with arrhythmia recurrence necessitating a second ablation procedure. This fact can help in planning the second ablation procedure. Persistent PVI seems to have no prognostic role regarding the three months arrhythmia recurrence after Redo-Ablation.

Abstract The achievement of a clinical response to the first part of induction chemotherapy has been considered for predicting survival in patients with aggressive non Hodgkin lymphoma (NHL). In April 2000, the Gruppo Italiano Studio Linfomi (GISL) started the LA05 trial with the aim of assessing different treatment modalities according to response to 4 initial courses of chemotherapy (CT) assessed according to the international response criteria for NHL. Untreated Patients younger than 65 years with histologically confirmed diagnosis of aggressive NHLs were eligible to the study. All stages and all IPI groups were allowed. After 4 courses of CT patients achieving at least a PR >75% were to be treated with two additional courses of CT (group 1); those achieving PR <75% were randomized to receive either additional 4 courses of the same CT or a modified HDS program followed by autologous stem cell support (group 2); patients with SD or PD were to be assigned to salvage programs (group 3). The study CT regimen was ProMECE-CytaBOM; in July 2005, the protocol was amended allowing the use of other CT regimens, including CHOP and MACOP-B, and recommending the addition of Rituximab for B-cell NHL. D The study is still ongoing and we are not yet able to provide data about the efficacy of HDS in patients of group 2. We present the preliminary results of efficacy of the LA05 trial, in particular focused on the outcome of group 1 patients. As of June 2006, 341 patients were enrolled. Eighty percent of cases had DLBCL, 12% PTCL, 5% GIII FL and 3% MCL. Median age at diagnosis was 49 years (range 18–67). Sixty percent had stage III–IV disease and 38% had a bulky mass. IPI was low (0–1) in 52%, intermediate (2) in 22% and high (3+) in 26% of cases. After 4 courses of CT, 265 patients were evaluable for response; one-hundred and seventy patients (64%) achieved a CR or a PR >75%, 49 (19%) achieved a PR <75% and 46 (17%) had SD or PD. The probability of achieving a CR or a PR >75% was 74%, 62% and 42%, for patients with an initial IPI of 0–1, 2 or 3+. At the end of treatment program, a CR was achieved in 57% of cases and a PR in 14%. After a median follow-up of 21 months (range 1–73), the 2-year OS was 69% (IC 95% 62–75), being 85%, 65% and 25% for group 1, 2 and 3 respectively (p<0.001). Two-year OS was 88%, 78% and 78% for patient in group 1 with and IPI of 0–1, 2 and 3+ respectively (p=NS). The achievement of a CR or a PR >75% after the first part of initial CT overcomes the prognostic role of IPI in patients with aggressive NHL.

e15541 Background: Apolipoprotein b (apob), apolipoprotein a1 (apoa1), and lactate dehydrogenase (LDH) levels are circulating biomarkers that relate to tumor inflammation. This study aimed to evaluate the prognostic role of apob/apoa1 and LDH in resectable colorectal cancer (CRC). Methods: 513 patients of colorectal cancer (CRC) from Hubei cancer hospital were included finally, and we collected the pre-operative laboratory results within a week before surgery. We combined the two indicators and divided them into three groups (group 1: apob/apoa1-LDH low; group 2: apob/apoa1 or LDH high; group 3: apob/apoa1-LDH high). Kaplan-Meier survival analysis, univariate COX regression and multivariate COX regression were used to assess the prognoses of colorectal cancer patients. Results: The median follow-up was 35 months. Our study found that the prognosis of group 1 was better than group 2 in both overall survival (88.2% vs. 75.4% vs. 61.9%) (P≤0.001) and diseases-free survival (77.4% vs. 64.7% vs. 42.8%) (P≤0.001), and group 3 was the worst. By multivariate analysis, the new predictive marker obtained by combining apob/apoa1 and LDH could independently predict outcomes in CRC [overall survival: (HR: 1.487; 95% CI, 1.074-2.061); diseases-free survival (HR: 1.381; 95% CI, 1.045-1.827)]. Conclusions: New marker based on apob/apoa1 and LDH is useful for predicting the prognosis of patients with CRC. However, more research is needed in the future.

Introduction: There have been many forms of remodeling reported to play a role in the concept of “atrial fibrillation (AF) begets atrial fibrillation.” The role of intrinsic cardiac nervous system (ICNS) in this remodeling process was evaluated in this study. Methods: Continuous rapid pacing (1200 bpm, 2× threshold, TH) was performed at the left atrial appendage to maintain AF. Group 1 (N=7): 6-hours of pacing followed by ganglionated plexi (GP) ablation, both left and right side; Group 2 (N=7): GP ablation followed by 6-hours of pacing. At 2x and 10x TH, the effective refractory period (ERP) and window of vulnerability (WOV), i.e., longest-shortest coupling of premature stimulus which induced AF in milliseconds (ms), were measured at the left atrium, right atrium and pulmonary veins (PVs) every hour during the 6-hours of pacing before and after GP ablation. Results: In group 1 (rapid pacing with GP intact) ERP progressively shortened in the first two hours and then stabilized both at 2×TH and 10×TH (Figure 1A ), however, WOV progressively widened throughout the time period (Figure 1B ). After GP ablation, ERP was significantly longer than prior to ablation and AF could not be induced (WOV=0, p<0.01) at any pacing site at either 2×TH or 10×TH (Figure 1B ). In group 2 (initial GP ablation), ERP exhibited a slightly increasing trend as the pacing time increased. AF could not be induced in 6/7 dogs during the 6-hour pacing, and was inducible in 1/7 with a cumulative WOV of only 10 ms. Conclusion: The ICNS is crucial for the process of “AF begets AF” in the acute stages of remodeling by rapid atrial pacing.

Objectives Triglyceride-glucose index (TyG index), which is defined as the simple and novel marker of insulin resistance, is becoming increasingly important as a promising predictive marker for atherosclerotic diseases. Chronic limb-threatening ischemia is defined as the most advanced stage of the lower extremity peripheral artery disease, whose main cause is atherosclerosis and is associated in this respect with amputation, impaired quality of life, and mortality. The main purpose of the present study was to investigate the relation between the calculated TyG index values and chronic limb-threatening ischemia development. Methods A total of 296 patients who were diagnosed with lower extremity peripheral artery disease in our outpatient clinic between October 2018 and October 2020 were included in this study retrospectively. Two groups were formed by clinically staging the patients according to Rutherford Classification. Patients who did not develop chronic limb-threatening ischemia were classified as “Group 1” ( n = 224) and those who developed were classified as “Group 2” ( n = 72). Results The mean TyG index values that were calculated in Group 2 were significantly higher than in Group 1 (9.27 ± 0.31 vs. 9.00 ± 0.34, p < 0.001). In the multivariate logistic regression analysis conducted to determine the predictors of chronic limb-threatening ischemia development, C-reactive protein (OR [Odds Ratio]: 1.220, 95% CI [confidence interval]: 1.092–1.363, p < 0.001), high-density lipoprotein cholesterol (OR: 0.775, 95% CI: 0.715–0.839, p < 0.001) and TyG index (OR: 5.796, 95% CI: 2.050–16.382, p = 0.001) were identified as independent predictors. Receiver operating characteristic analysis revealed that the cut-off value of TyG index was 9.13 (area under the curve: 0.721, p < 0.001) with 70.8% sensitivity and 65.2% specificity. The TyG index was significantly correlated with Rutherford category, high-density lipoprotein cholesterol and mean platelet volume. Conclusions Chronic limb-threatening ischemia development may be predicted with the TyG index value, which is calculated easily from routine biochemical parameters, in patients diagnosed with lower extremity peripheral artery disease.

Abstract Background Orthodontic tooth movement (OTM) has been shown to induce osteocyte apoptosis in alveolar bone shortly after force application. However, how osteocyte apoptosis affects orthodontic tooth movement is unknown. The goal of this study was to assess the effect of inhibition of osteocyte apoptosis on osteoclastogenesis, changes in the alveolar bone density, and the magnitude of OTM using a bisphosphonate analog (IG9402), a drug that affects osteocyte and osteoblast apoptosis but does not affect osteoclasts. Material and methods Two sets of experiments were performed. Experiment 1 was used to specifically evaluate the effect of IG9402 on osteocyte apoptosis in the alveolar bone during 24 h of OTM. For this experiment, twelve mice were divided into two groups: group 1, saline administration + OTM24-h (n=6), and group 2, IG9402 administration + OTM24-h (n=6). The contralateral unloaded sides served as the control. The goal of experiment 2 was to evaluate the role of osteocyte apoptosis on OTM magnitude and osteoclastogenesis 10 days after OTM. Twenty mice were divided into 4 groups: group 1, saline administration without OTM (n=5); group 2, IG9402 administration without OTM (n=5); group 3, saline + OTM10-day (n=6); and group 4, IG9402 + OTM10-day (n=4). For both experiments, tooth movement was achieved using Ultra Light (25g) Sentalloy Closed Coil Springs attached between the first maxillary molar and the central incisor. Linear measurements of tooth movement and alveolar bone density (BVF) were assessed by MicroCT analysis. Cell death (or apoptosis) was assessed by terminal dUTP nick-end labeling (TUNEL) assay, while osteoclast and macrophage formation were assessed by tartrate-resistant acid phosphatase (TRAP) staining and F4/80+ immunostaining. Results We found that IG9402 significantly blocked osteocyte apoptosis in alveolar bone (AB) at 24 h of OTM. At 10 days, IG9402 prevented OTM-induced loss of alveolar bone density and changed the morphology and quality of osteoclasts and macrophages, but did not significantly affect the amount of tooth movement. Conclusion Our study demonstrates that osteocyte apoptosis may play a significant role in osteoclast and macrophage formation during OTM, but does not seem to play a role in the magnitude of orthodontic tooth movement.

Many parameters included in the Anticoagulation and Risk Factors in Atrial Fibrillation (ATRIA) and CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, stroke, vascular disease, age 65-74 years, sex category) scores also predict coronary artery disease (CAD). We modified the ATRIA score (ATRIA-HSV) by adding hyperlipidemia, smoking, and vascular disease and also male sex instead of female. We evaluated whether the CHA2DS2-VASc, CHA2DS2-VASc-HS, ATRIA, and ATRIA-HSV scores predict severe CAD. Consecutive patients with coronary angiography were prospectively included. A ≥50% stenosis in ≥1epicardial coronary artery (CA) was defined as severe CAD. Patient with normal CA (n = 210) were defined as group 1, with <50% CA stenosis (n = 178) as group 2, and with ≥50% stenosis (n = 297) as group 3. The mean ATRIA, ATRIA-HSV, CHA2DS2-VASc, and CHA2DS2VASc-HS scores increased from group 1 to group 3. A correlation was found between the Synergy between PCI with Taxus and Cardiac Surgery score and ATRIA ( r = 0.570), ATRIA-HSV ( r = 0.614), CHA2DS2-VASc ( r = 0.428), and CHA2DS2-VASc-HS ( r = 0.500) scores ( Ps < .005). Pairwise comparisons of receiver operating characteristics curves showed that ATRIA-HSV (>3 area under curve [AUC]: 0.874) and ATRIA (>3, AUC: 0.854) have a better performance than CHA2DS2-VASc (>1, AUC: 0.746) and CHA2DS2-VASc-HS (>2, AUC: 0.769). In conclusion, the ATRIA and ATRIA-HSV scores are simple and may be useful to predict severe CAD.

This phase II randomized controlled trial tested whether intracoronary autologous CD34+ cell therapy could further improve left ventricular (LV) systolic function in patients with diffuse coronary artery disease (CAD) with relatively preserved LV ejection fraction (defined as LVEF >40%) unsuitable for coronary intervention. Between December 2013 and November 2017, 60 consecutive patients were randomly allocated into group 1 (CD34+ cells, 3.0 × 107/vessel/n = 30) and group 2 (optimal medical therapy; n = 30). All patients were followed for one year, and preclinical and clinical parameters were compared between two groups. Three-dimensional echocardiography demonstrated no significant difference in LVEF between groups 1 and 2 (54.9% vs. 51.0%, respectively, p = 0.295) at 12 months. However, compared with baseline, 12-month LVEF was significantly increased in group 1 (p < 0.001) but not in group 2 (p = 0.297). From baseline, there were gradual increases in LVEF in group 1 compared to those in group 2 at 1-month, 3-months, 6-months and 12 months (+1.6%, +2.2%, +2.9% and +4.6% in the group 1 vs. −1.6%, −1.5%, −1.4% and −0.9% in the group 2; all p < 0.05). Additionally, one-year angiogenesis (2.8 ± 0.9 vs. 1.3 ± 1.1), angina (0.4 ± 0.8 vs. 1.8 ± 0.9) and HF (0.7 ± 0.8 vs. 1.8 ± 0.6) scores were significantly improved in group 1 compared to those in group 2 (all p < 0.001). In conclusion, autologous CD34+ cell therapy gradually and effectively improved LV systolic function in patients with diffuse CAD and preserved LVEF who were non-candidates for coronary intervention (Trial registration: ISRCTN26002902 on the website of ISRCTN registry).

Abstract Study question To assess the role of subcutaneous granulocyte colony-stimulating factor (G-CSF) in thin endometrium cases. Summary answer G CSF has beneficial role to improve the endometrium thickness in thin endometrium. What is known already Endometrium is very important for embryo implantation and the endometrial thickness is the marker of receptivity of the endometrium. Study design, size, duration Study design - Retrospective analysis Size - 88 infertile females with thin endometrium (&lt; 7 mm) in the age group of 23 to 40 years Duration - one year. Participants/materials, setting, methods In the group 1 of 44 females, subcutaneous infusion of G CSF (300 mcg/ml) was added along with other supplements and if lining was not more than 7 mm in 72 hours, then second infusion was given. In the group 2 of 44 females, only estradiol valerate and sildenafil were given.The efficacy of G CSF was evaluated by assessing the endometrium thickness before embryo transfer, pregnancy rates and clinical pregnancy rates. Main results and the role of chance There was no difference between the two groups regarding demographic variables, egg reserve, sperm parameters, number of embryos transferred and embryo quality. . The pregnancy rate was 60% (24 out of 40 cases) in the group 1 that was significantly higher than in-group 2 that was 31% (9 out of 29 cases) with p value &lt; 0.0001. The clinical pregnancy rate was also significantly higher in-group 1 (55%) as compared to group 2 (24%) with p value &lt; 0.0001. Limitations, reasons for caution Further larger cohort studies are required to explore the subcutaneous role of G CSF in thin endometrium. Wider implications of the findings: Granulocyte colony-stimulating factor has beneficial role to improve the endometrium thickness in thin endometrium. In most of previous studies, the intrauterine infusion of G CSF was given to improve the uterine lining. This is one of the few studies done that showed subcutaneous role of G CSF in thin endometrium. Trial registration number Not applicable

Abstract Background Computational pressure-flow dynamics derived fractional flow reserve (caFFR) is a novel index developed to evaluate the extent of myocardial ischemia in patients with coronary artery disease (CAD), which eliminates the need of invasive pressure guidewire and hyperaemic stimulus in conventional fractional flow reserve (FFR) measurement. Studies have shown improved clinical outcomes associated with adherence to functional myocardial ischemia assessment when deciding to perform percutaneous coronary intervention (PCI) at a per-patient level. However, the clinical significance of such treatment adherence at a per-vessel level remains uncertain. Methods A total of 928 patients (mean age 66.2±10.5, male 72.7%) with stable CAD were included in this study. The caFFR of all three major coronary vessels were obtained for every patient, and the FFR threshold of 0.8 was adopted as the threshold for caFFR to indicate functionally significant artery stenosis which warrants PCI, and vice versa. Based on the caFFR of each major coronary vessel and whether PCI was performed to the respective vessel, patients were stratified into 0–1 vessel with treatment adherence group (group 1) (n=105), 2 vessels with treatment adherence group (group 2) (n=338), and 3 vessels with treatment adherence group (group 3) (n=485). The primary endpoint was major adverse cardiac events (MACE), defined as a composite of all-cause mortality, non-fatal myocardial infarction and any subsequent revascularization. Results The severity of CAD based on SYNTAX score assessment was 18.6±10.2 in group 1, 14.6±8.9 in group 2, and 11.5±9.9 in group 3 (P&lt;0.001). The rates of MACE at 3 years were significantly different across groups 1, 2 and 3 (17.1% vs. 12.1% vs. 7.4%; P=0.004). With reference to group 3, the risk of MACE at 3 years was increased in group 2 (adjusted hazard ratio [HR]=1.597; 95% confidence interval [CI]=1.020–2.501; P=0.041), and further increased in group 1 (adjusted HR=1.933; 95% CI=1.081–3.457; P=0.026). Conclusion In stable CAD patients, the risk of MACE is incremental when fewer major coronary vessels are treated with adherence to caFFR threshold of 0.8. Per-vessel treatment adherence significantly affects clinical outcomes in terms of MACE. FUNDunding Acknowledgement Type of funding sources: None.

The aim: To estimate the dynamics of echocardiographic parameters in patients with CAD within 5 years after revascularization. Material and methods: 50 persons (males/females 39/11; mean age 59.9±9.3 years; STEMI 76%, non-STEMI 24%) were divided into two groups: n=38 after PCI with stenting (PCIwS); n=12 after CABG. Observation included regular echocardiography with LV myocardial mass (LVMM) and geometry estimation. Results: Groups were comparable by age, co-morbidity, BP, heart rate and BMI. Significantly severe baseline LV hypertrophy (LVH) and left atrial enlargement (LAE) in group 2 explained by spread coronary atherosclerosis. Later progressive LAE (4.37±0.22 cm, P0-60<0.05) in group 1, and aortic/LV dilatation (+0.4/+1.0 cm, respectively, both P0-60<0.05) in group 2 developed. In two years LVMM index increased by 13.4/17.5% in groups 1/2, respectively. Normal geometry and concentric remodeling completely disappeared in 3/1.5 years after PCIwS/CABG, respectively. Conclusions: Within the 1st year after revascularization, patients with CABG had more severe LVH. In 5 years after PCIwS the ratio between concentric/eccentric LVH was 2:1, whereas after CABG – 1:2.
