Celem artykułu jest wykazanie związku pomiędzy ponowoczesnością i totalitaryzmami oraz wychowaniem człowieka. Przyjętym założeniem jest istnienie zróżnicowanej ontycznie rzeczywistości, której integralną częścią jest życie człowieka, pomiędzy różnymi porządkami istnienia: immanentnym (biopsychospołecznym) i transcendentnym (egzystencjalnym, metafizycznym i religijnym), w obliczu którego człowiek staje się tym, kim może i być powinien. Na podstawie analizy rozważań francuskiej myślicielki Chantal Delsol (ur. 1947) można sądzić, że wobec przesłoniętej transcendencji – zarówno w minionych totalitaryzmach, jak i współcześnie – człowiek wskutek absolutyzacji inherentnych kryteriów prawomocności tego, co immanentne, zostaje zredukowany do swoich uwarunkowań biopsychospołecznych. W konsekwencji świat staje się polem do eksperymentów społecznych, dokonywanych za pomocą terroru, bądź bardziej subtelnych środków inżynierii społecznej. Wychowanie jawi się wówczas jako ochrona człowieka przed totalitarnym potencjałem ludzkiego zbiorowego istnienia, a zatem także przed nim samym.

Background: Genetic loss-of-function variants in ANGPTL3 are associated with lower levels of plasma lipids. Vupanorsen is a hepatically targeted antisense oligonucleotide that inhibits Angiopoietin-like 3 (ANGPTL3) protein synthesis. Methods: Adults with non–high-density lipoprotein cholesterol (non-HDL-C) ≥100 mg/dL and triglycerides 150 to 500 mg/dL on statin therapy were randomized in a double-blind fashion to placebo or 1 of 7 vupanorsen dose regimens (80, 120, or 160 mg SC every 4 weeks, or 60, 80, 120, or 160 mg SC every 2 weeks). The primary end point was placebo-adjusted percentage change from baseline in non–HDL-C at 24 weeks. Secondary end points included placebo-adjusted percentage changes from baseline in triglycerides, low-density lipoprotein cholesterol (LDL-C), apolipoprotein B (ApoB), and ANGPTL3. Results: Two hundred eighty-six subjects were randomized: 44 to placebo and 242 to vupanorsen. The median age was 64 (interquartile range, 58–69) years, 44% were female, the median non–HDL-C was 132.4 (interquartile range, 118.0–154.1) mg/dL, and the median triglycerides were 216.2 (interquartile range, 181.4–270.4) mg/dL. Vupanorsen resulted in significant decreases from baseline over placebo in non–HDL-C ranging from 22.0% in the 60 mg every 2 weeks arm to 27.7% in the 80 mg every 2 weeks arm (all P P P 3× elevations of alanine aminotransferase or aspartate aminotransferase were more common at higher total monthly doses (up to 33.3% and 44.4%, respectively), and there was a dose-dependent increase in hepatic fat fraction (up to 76%). Conclusions: Vupanorsen administered at monthly equivalent doses from 80 to 320 mg significantly reduced non–HDL-C and additional lipid parameters. Injection site reactions and liver enzyme elevations were more frequent at higher doses, and there was a dose-dependent increase in hepatic fat fraction.

Functional lesion assessment in stable coronary disease is considered the gold standard. The result of fractional flow reserve (FFR) in stable coronary disease is often a decision-maker for patient qualification. Taking into account the paramount position of FFR, it is crucial to acknowledge and reduce all potential bias.In the present study, we quantified the influence of elevated HR on FFR results using a preclinical model and then validated the results in a clinical setting.The relationship between FFR and HR was first explored experimentally in a porcine model. A clinical validation study was conducted in patients with isolated moderate lesions in the left anterior descending artery (LAD) or right coronary artery (RCA). In both the experimental and clinical arms, FFR was measured at resting HR and with pacing at 100, 130, 160, and 180 (for pigs) beats per minute. In the porcine model and in the clinical settings, a significant correlation between FFR and HR was confirmed in the LAD (r = 0.89, p .0001; r = 0.53, p = .00002), but not in the RCA (r = -0.19, p = .5; r = 0.14, p = .3). Post hoc analyses revealed that the FFR values in the LAD at 130/min and above tended to be significantly different from the baseline HR.The results of this study indicate that in an experimental setting, tachycardia might be responsible for an overestimation of FFR results in LAD lesions.

Introduction The rate of atherectomy utilization in peripheral artery diseases (PAD) is growing. The two atherectomy devices available on the market and used most frequently are the directional and rotational ones. Nonetheless, there is a lack of direct comparison between these two types of atherectomy in PAD. Aim To compare the long-term outcomes after PAD endovascular revascularization with two types of atherectomies: rotational (AR) (Phoenix Philips) and directional (AD) (SilverHawk Medtronic). Material and methods This was a single-center, retrospective study of obstructive and symptomatic PAD patients who underwent revascularization with atherectomy. The endpoints were considered as target lesion revascularization (TLR), death, amputations and bailout stenting (BS). Results The AR group consisted of 97 patients, while the AD group consisted of 85 individuals. There were no significant differences between the groups in terms of baseline characteristics except for an increased critical limb ischemia (CLI) prevalence in the AR group. The mean follow-up for AD and AR was 282.6 ±147.4 and 255.7 ±186.1 days, respectively (p = 0.44). There were no significant differences in the death rate (AD: 1 (1.7%) vs. AR: 5 (5.7%); p = 0.54), amputations (AD: 2 (2.3%) vs. AR: 5 (5.7%); p = 0.45) or bailout stenting (AD: 2 (2.3%) vs. AR: 3 (3.2%); p = 0.74), whereas TLR was more frequent in the AD group (AD: 25 (29%) vs. AR: 15 (15.9%; p = 0.03). The Kaplan-Meier analysis showed no significant differences between the groups in time to TLR, amputation or death. Conclusions In this hypothesis-generating study the AR had a lower rate of TLR when compared to the AD. Nevertheless, this should be confirmed in further controlled randomized trials.

- Abstract
Education in the light of the Platonic philosophy of transcendence appears as ennobling the soul of man by participating in higher over-conceptual orders of existence and experiencing the presence of transcendence in immanence. The condition of education would therefore appear as admitting infinitely diverse – mental and phenomenal – pedagogical experience, the transcendent idea of education, what is in each experience over-immanent, over-conventional and ontologically independent. Education thus conceived opens to the richness of the experience of transcendence in immanence.

Background: Whereas the efficacy and safety of intravascular lithotripsy (IVL) have been confirmed in de novo calcified coronary lesions, little is known about its utility in treating stent underexpansion. This study aimed to investigate the impact of IVL in treating stent underexpansion. Methods and Results: Consecutive patients with stent underexpansion treated with IVL entered the multicenter IVL-Dragon Registry. The procedural success (primary efficacy endpoint) was defined as a relative stent expansion >80%. Thirty days device-oriented composite endpoint (DOCE) (defined as a composite of cardiac death, target lesion revascularization, or target vessel myocardial infarction) was the secondary endpoint. A total of 62 patients were enrolled. The primary efficacy endpoint was achieved in 72.6% of patients. Both stent underexpansion 58.5% (47.5–69.7) vs. 11.4% (5.8–20.7), p < 0.001, and the stenotic area 82.6% (72.4–90.8) vs. 21.5% (11.1–37.2), p < 0.001, measured by quantitative coronary angiography improved significantly after IVL. Intravascular imaging confirmed increased stent expansion following IVL from 37.5% (16.0–66.0) to 86.0% (69.2–90.7), p < 0.001, by optical coherence tomography and from 57.0% (31.5–77.2) to 89.0% (85.0–92.0), p = 0.002, by intravascular ultrasound. Secondary endpoint occurred in one (1.6%) patient caused by cardiac death. There was no target lesion revascularization or target vessel myocardial infarction during the 30-day follow-up. Conclusions: In this real-life, largest-to-date analysis of IVL use to manage underexpanded stent, IVL proved to be an effective and safe method for facilitating stent expansion and increasing luminal gain.

Introduction The population of patients with lower limb atherosclerosis includes a considerable proportion of individuals with long superficial femoral artery (SFA) lesions. Chronic total occlusions (CTOs) represent the "last frontier" of percutaneous interventions. While open strategies are considered earlier as standard management for these lesions, the results of a number of trials indicate that endovascular management might become an effective alternative to surgery. Material and methods This paper presents 5-year outcomes of a first-in-man (FIM) study (before CE mark) and the registry of OCT Guided Ocelot Catheter (Avinger) for chronic total occlusions of the superficial femoral artery. The study group comprised 10 patients with Rutherford 3 lower limb ischemia including nine men and one woman. Results The efficacy of the primary intervention was 90%. Angiography performed at 6 months of the procedure, according to the study protocol, revealed 3 and 1 cases of restenosis and reocclusion, respectively, repaired using PTA and open common and deep femoral artery patch plasty. Doppler ultrasound performed at 1, 2 and 5 years after the primary intervention did not reveal significant target vessel restenosis. The primary and primary-assisted patency was 89%. During a 5-year follow-up, four peripheral percutaneous interventions and one femoropopliteal bypass surgery were performed in non-target limbs. There were no cardiovascular deaths, myocardial infarction or stroke and no amputation was required. Conclusions This is a first-in-man study reporting long-term follow-up after SFA CTO revascularization using the Ocelot catheter. The catheter proved to have a satisfactory safety profile and a high proportion of CTO crossings. A 5-year follow-up revealed high primary and primary-assisted patency rates.

We sought to compare the safety and efficiency of Tiger-2 in the right radial and Judkins catheter in the left radial access. We retrospectively collected data of 487 patients, involving 172 patients after coronary angiography with Judkins on the left radial artery and 315 patients with Tiger-2 on the right radial artery access. There were no differences in baseline characteristics, except for hypertension ratio and mean age. There was a difference in pulse absence on the radial artery. The volume of contrast used was higher in the Judkins group. Both groups differed in the amount of drugs administered (NTG and heparin). Fluorescence times were comparable between groups. Radiation dosage and AK was significantly greater in the Tiger-2 group. The Tiger-2 catheters were significantly more often changed to another type of catheter (100 changes) than the Judkins (12 changes). However, there was no statistical difference in access site change. Judkins with left radial access seems to be a safer option because of the lower radiation exposure and less incidence of complications than Tiger-2 with right radial access, however, it requires a higher volume of contrast.

Aims: The DESSOLVE III OCT substudy aimed to compare serially neointimal hyperplasia volume obstruction (%VO) between the thin-strut MiStent with early polymer elimination and nine-month sustained drug release from microcrystalline sirolimus and the durable polymer-coated everolimus-eluting XIENCE stent at six and 24 months after implantation. Methods and results: The efficacy endpoint was %VO, calculated as abluminal neointimal volume/stent volume. Thirty-six patients (MiStent 16 patients, 16 lesions; XIENCE 20 patients, 22 lesions) underwent serial OCT evaluation at both six and 24 months. At six months, mean abluminal %VO was significantly lower in the MiStent group than in the XIENCE group (14.54±3.70% vs 19.11±6.70%; p=0.011), whereas the difference in %VO between the two groups decreased at 24 months (20.88±5.72% vs 23.50±7.33%; p=0.24). There was no significant difference in percentage malapposed struts and percentage uncovered struts between the two groups at both time points. Conclusions: In the serial comparative OCT analysis of the MiStent versus the XIENCE, the MiStent showed a more favourable efficacy for preventing neointimal formation with comparable strut tissue coverage, as compared with the XIENCE at six months, but this difference in %VO decreased at 24 months so that the difference in neointima at 24 months was no longer significant.

Catheter-based renal denervation (RDN) has been investigated for hypertension (HTN) treatment with variable success. One of the novel approaches to RDN is the delivery of micro-doses of dehydrated alcohol to the adventitial space of the renal artery to perform perivascular ablation of the sympathetic nerves. We sought to assess the safety and efficiency of transcatheter alcohol-mediated perivascular renal denervation in patients with resistant hypertension. Fifty adult patients who had been referred for resistant HTN were screened. To qualify for the study, the patients had to have a mean 24 h systolic pressure &ge, 135 mmHg based upon ambulatory blood pressure monitoring (ABPM) and acceptable renal artery anatomy confirmed by the contrast computer tomography (AngioCT) and nephrologist consultation. Ten patients were eligible for chemical RND. There were no safety issues throughout the 24 months of follow-ups. The mean decrease in the office BP (OBP) was significant during 24 months of follow-up (p <, 0.01). The difference in the BP in the ABPM was statistically significant in the 1st, 3rd and 12th months (p <, 0.01), whereas during the 3-month follow-up, a trend was observed. The modifications of anti-hypertension drugs throughout the follow-up period were minimal. This study has shown that transcatheter alcohol-mediated renal denervation in patients with resistant hypertension is feasible and safe. Nevertheless, it is a hypothesis-generating study.

Objectives This study has reported 10-year clinical follow-up of patients enrolled in the prospective, randomized LE MANS (Left Main Stenting) trial. Background The very long-term outcome after left main stenting in comparison with surgical revascularization remains unknown. Methods In this prospective, multicenter trial, we randomly assigned 105 patients with unprotected left main coronary artery stenosis with low and medium complexity of coexisting coronary artery disease according to SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) score to percutaneous coronary intervention (PCI) with stenting (n = 52) or coronary artery bypass grafting (CABG) (n = 53). Drug-eluting stents were implanted in 35%, whereas arterial grafts to the left anterior descending artery were utilized in 81%. Currently, the mean long-term follow-up was collected at 9.8 ± 1.0 years. Follow up for all-cause mortality is complete, whereas the incidence of major adverse cardiovascular and cerebral events (MACCE) was reported from 90% of patients. Ambulatory follow-up was completed in 46 (43.9%) patients. Results At 10 years, there was a trend toward higher ejection fraction in stenting when compared with surgery (54.9 ± 8.3% vs. 49.8 ± 10.3%; p = 0.07). The mortality (21.6% vs. 30.2%; p = 0.41) and MACCE (51.1% vs. 64.4%; p = 0.28) were statistically not different between groups; however, numerically the difference was in favor of stenting. Similarly, there was no difference in the occurrence of myocardial infarction (8.7 vs. 10.4%; p = 0.62), stroke (4.3 vs. 6.3%; p = 0.68), and repeated revascularization rates (26.1% vs. 31.3%; p = 0.64). The probability of very long-term survival up to 14 years was comparable between PCI and CABG (74.2% vs. 67.5%; p = 0.34; hazard ratio: 1.45, 95% confidence interval: 0.67 to 3.13); however, there was a trend toward higher MACCE-free survival in the PCI group (34.7% vs. 22.1%; p = 0.06; hazard ratio: 1.71, 95% confidence interval: 0.97 to 2.99). Conclusions In patients with unprotected left main coronary artery stenosis with low and medium complexity of coexisting coronary artery disease, stenting offers numerically, but statistically nonsignificant, favorable long-term outcome up to 10 years in terms of safety and efficacy outcome measures, therefore, constitutes an alternative therapy for CABG.

Introduction: 4D Ultrasound technology merging the Power Doppler option called High-Definition Flow (HDF) with Spatio-Temporal Image Correlation (STIC) is used in gynaecology and obstetrics. It seems to be a promising tool in assessing tissue vascularisation. The aim of the paper was to assess whether HDF STIC technique could be a useful tool for the evaluation of gastro-entero-pancreatic neuroendocrine neoplasm (GEP-NEN) advancement. Material and methods: Forty-eight patients [mean age 57.7 ± 10.3 years; male 40.9% (n = 18)] diagnosed with metastatic GEP-NENs were included in the analysis. All subjects were enrolled in the Department of Endocrinology and Neuroendocrine Tumours, Medical University of Silesia, Katowice. We analysed liver metastases. Patients with G3 grading or faintly vascularised lesions were excluded. HDF STIC volumes were acquired during USG examination. 4D indices [volumetric pulsatility index (vPI) and volumetric systolic/diastolic index (vS/D)] were calculated using dedicated software. Results: There were no correlations between vS/D and Ki-67 [p = 0.67; r = –0.19; (–0.28–0.19)], CgA [p = 0.47; r = –0.11; (–0.38–0,19)], 5-HIAA [p = 0.52; r = –0.09 (–0.37–0.2)], serotonin [p = 0.83; r = –0.03 (–0.32–0.26)], and VCAM-1 (p = 0.62; r = 0.09 (–03–0.47)]. The were no correlations between vPI and Ki-67 [p = 0.29; r = –0.16 (–0.45–0.14)], CgA (p = 0.46; r = –0.11 (–0.39–0.19)], 5-HIAA [p = 0.52; r = –0.09 (–0.37–0.2)], serotonin [p = 0.82; r = –0.03 (–0.32–0.26)], and VCAM-1 (p = 0.62; r = –0.09 (–03–0.47)]. There was no significant difference between carcinoid versus non-carcinoid patients if compared by vS/D and vPI (p = 0.62, p = 0.61, respectively). Conclusions: HDF STIC seems not to be an efficient marker to assess advancement of NENs, due to lack of correlation with widely used and approved markers of progression.

Despite proven efficacy of cardiac rehabilitation (CR) in reducing the all-cause mortality in patients after myocardial revascularization, the penetration of CR, due to patient-related factors and referral rates remains limited. To improve the outcomes, home-based tele-rehabilitation (TR) has been proposed recently. In theory TR enhances the effects of standard CR procedures due to implementation of an intelligent monitoring system designed to ensure optimal training through on-demand transmission of vital signs, aimed at motivating the patients through daily schedule reminders, setting daily goals and creating a platform for mutual feedback. Several meta-analyses assessing various studies comparing these two methods (CR and TR) have proven that they are at least equally effective, with some of the research showing superiority of TR. Although there was a small sample size, lack of long-term follow-up, reporting effects of TR itself, no integration with tools designed for coaching, motivating and promoting a healthy lifestyle constitutes an important limitation. The latter carries a hopeful prognosis for improvement when utilizing a broad-spectrum approach, especially with use of dedicated technological solutions exploiting the fact of a large and yet rapidly increasing penetration of smartphones, mobile PCs and tablets in the population. The above-mentioned findings worked as the basis and rationale for commencing the RESTORE project aimed at developing and delivering state-of-the-art, comprehensive TR for patients after myocardial revascularization and evaluating its molecular aspect in view of how it influences the atherosclerosis progression attenuation. This paper presents the current state and rationale behind the project based on up-to-date TR efficacy data.

Background: Fast releasing, rapamycin-eluting stents, although safe, showed inferior results with regard to inhibition of restenosis. Aim: Therefore, we report vascular effects of a novel, biodegradable polymer stent matrix with elevated sirolimus dose and fast release kinetics (ed-frSES, Alex, Balton) in the porcine coronary in-stent restenosis model. Methods: A total of 19 stents were implanted with 120% overstretch in the coronary arteries of seven domestic pigs: seven ed-frSES with 1.3 μg/mm2 of sirolimus, eight frSES with 1 μg/mm2 of sirolimus, and eight bare metal stents (BMS). For the following 28 days, coronary angiography was performed, animals were sacrificed, and the stented segments harvested for histopathological evaluation. Results: In angiography at 28 days the late lumen loss was lowest in the elevated dose sirolimus eluting stent (SES) (ed-frSES: 0.20 ± 0.2 vs. frSES: 0.80 ± 0.5 vs. BMS: 0.96 ± 0.5 mm, p < 0.01). This was confirmed in the morphometric evaluation in histopathology as represented by a significant and dose-dependent decrease in the percentage area of stenosis (ed-frSES: 22.4 ± 12.7% vs. frSES: 35 ± 10.7% vs. BMS: 47.5 ± 12.5%, p < 0.01). There was no peri-strut inflammation in any of the groups. However, the endothelialisation score was numerically not meaningfully decreased in ed-frSES (ed-frSES: 2.93 vs. frSES: 3. vs. BMS: 3, p = 0.05). Signs of fibrin were also noted in ed-frSES (ed-frSES: 0.4 vs. frSES: 0 vs. BMS: 0, p = 0.05). Conclusions: Sirolimus dose-dependent vascular response was reported. The elevated dose, fast releasing SES shows satisfactory vascular healing, similar to regular dose, fast release SES, with improved efficacy in restenosis inhibition.

Background There is limited comparative clinical data regarding the safety and efficacy profile of paclitaxel delivery via balloon versus stent-polymer matrix. In this study, we aimed to compare the clinical and angiographic results of two different methods of paclitaxel delivery among patients undergoing percutaneous coronary intervention (PCI) for single de novo coronary lesions. Methods A total of 202 patients undergoing PCI due to symptomatic heart disease and at least one significant coronary artery lesion were prospectively enrolled in a multicenter non-inferiority trial. Eligible patients were randomized to a revascularization with either a paclitaxel eluting stent (PES = Coroflex Please, B.Braun) or a bare metal stent (BMS) followed by a paclitaxel coated balloon (PCB) dilation (BMS = Coroflex + PCB = Sequent Please, B.Braun). Clinical follow-up was obtained at 9 months in all patients, whereas angiographic in a subset of 94 (46.5%) patients. Results The baseline characteristics were well balanced between groups. At 9 months, the primary endpoint of in-stent late lumen loss in BMS + PCB was comparable and non-inferior to PES (0.21 ± 0.5 vs. 0.30 ± 0.7 mm, respectively. Pnon-inf

Objectives: We aimed to comprehensively evaluate poly-lactide polymer degradation and sirolimus release kinetics from a drug-eluting stent matrix in the in vivo setting using a nuclear magnetic resonance (NMR) method. Methods: In 22 domestic swine, 18 biodegradable polymer-only coated stents (BPSs) and 36 biodegradable polymer-coated sirolimus-eluting stents (BP-SES) were implanted in coronary arteries with 115% overstretch. The animals were sacrificed at 1, 3, 7, 14, 28, and 56 days following baseline procedures. Vessel segments with BPS were harvested to evaluate polymer degradation with a NMR method, whereas BP-SES to analyze sirolimus tissue uptake and retention. Additionally, 8 BP-SES were implanted for histological analysis for 90 days of follow-up. Results: The NMR showed a gradual absorption of the polymer over the 6 consecutive time points, from 5.48 µg of the polymer on the stent at 1-day follow-up, through 4.33 µg at 3 days, 3.16 µg at 7 days, 2.42 µg at 14 days, 1.92 µg at 28 days to 1.24 µg in the last day of the study. The curve of polymer degradation corresponds well with the pharmacokinetic profile of sirolimus eluted from its surface and measured at identical time points. In histopathology, at 90 days, complete healing and biocompatibility were reported. Conclusions: The utilization of NMR method for BP absorption kinetics evaluation is a useful tool, which may be widely adopted to test other biodegradable implants. Further, it may substantially improve their safety and efficacy by facilitating programmed polymer and drugs elution.

Background: Stent design may influence the outcomes, suggesting that adverse event rates vary according to free cell area and cell design. Open cell design technology of self-expandable stents, dedicated for carotid revascularisation has better deliverability, although closed cell technology is expected to cause fewer thromboembolic events. Aim: To evaluate the feasibility and vascular response of novel, hybrid cell, self-expandable nitinol stents (MER ® , Balton, Poland) implanted into porcine carotid arteries. Hybrid cell design combines open and closed cell technology. Methods: All tested stents were implanted with 10% overstretch into 10 carotid segments of Polish domestic pigs. Control angiography was obtained immediately before and after vascular interventions as well as 28 days after the procedure. Thereafter, animals were sacrificed, and the treated segments were harvested and evaluated in the independent histopathology laboratory. Results: All stents were easily introduced and implanted, showing good angiographic acute outcome. At 28 days, in the angiography, all vessels were patent with no signs of thrombi or excessive neointimal formation, with the late lumen loss of –0.11 ± 0.3 mm and percentage diameter stenosis 10.18 ± 8.1%. There was a 10% increase in the vessel reference diameter when compared to baseline (4.57 ± 0.5 vs. 4.96 ± 0.3 mm, p < 0.01). In the histopathology, mean area stenosis was 17.4% and mean intimal thickness was 0.20 mm. At histopathology, the mean injury, inflammation, and fibrin scores were low. Endothelialisation was complete in all stents, and neointimal tissue appeared moderately mature as shown by the moderate mean neointimal smooth muscle score. Nonetheless, histopathology shows one stent affected by peri-strut granulomas and one stent affected by marked mineralisation. Conclusions: The novel Polish self-expandable nitinol carotid stent with hybrid cell technology shows optimal biocompatibility and a vascular healing profile, and therefore may be introduced for first-in-man application.

Percutaneous coronary intervention (PCI) utilizing drug-eluting stents is becoming a very common revascularization technique in the dialysis cohort; therefore, we sought to identify the impact of dialysis on outcomes in this group of patients. This is a multicenter registry comparing results of 290 patients (186 with normal kidney function, 104 on dialysis) who underwent PCI with exclusive use of paclitaxel-eluting TAXUS stent. The primary endpoint was an assessment of major adverse cardiac events (MACE) at 1- and 2-year observation. Mean follow-up was 23.3 ± 6.1 months. Results at 12 months showed: MACE 11.8% vs. 7.7% (P = not significant [ns]), composite major adverse cardiac and cerebrovascular events (MACCE) 12.4% vs. 11.5% (P = ns), all-cause death 2.7% vs. 8.6% (P

Background: Although currently used devices for interventional closure of patent foramen ovale (PFO) are widely used due to the minimally invasive nature of this technique and high success rate, there is still a need to look for new materials and designs in order to improve the treatment outcomes. Aim: To evaluate the safety, biocompatibility, temporal healing patterns, and coverage dynamics of the new Polish PFO occluder (Balton, Warsaw, Poland) in a swine model — an observation that may assist the decision with regard to its first-in-human use and duration of anticoagulation therapy. Methods: In total, 12 pigs were scheduled for 28-day (n = 6) and 90-day follow-up (n = 6). In each animal, using a standard femoral venous approach, one PFO occluder was implanted and subsequently, in order to verify device position stability, the Minnesota manoeuvre was performed. At follow-up, all devices underwent a comprehensive evaluation with the use of high-resolution radiography (Faxitron MX-20 system), scanning electron microscopy (SEM), and standard histopathological techniques. Results: All PFO occluders were implanted successfully with no complications. The Faxitron revealed that all nitinol portions of the frame appeared intact and breaks were not detected at both studied time points. Overall, the device appeared to be well deployed in the atrial septum. At 28 days the average neointimal coverage of the right side of the PFO occluder by SEM was 92%; while in contrast the left side had less coverage, at 63%. At 90 days, the coverage of the right side of the occluder was 96.8%, while the left side of the PFO occluder improved and had similar coverage of 93.3%. By histology the endothelialisation process was virtually complete at 90 days. At the early time-point the overall inflammatory infiltrate was moderate and subsequently it diminished and was only mild or occasionally moderate at 90-day follow-up. At both time points the inflammatory reaction was limited to the neointimal tissue surrounding the device. Conclusions: Our study confirmed safety and good overall biocompatibility of the new Polish PFO occluder, which is comparable to other devices available on the market — an observation that supports the decision with regard to its first-in-human application. Neoendothelialisation was virtually completed at 90 days, suggesting that similarly to other widely used devices a minimum of three to six months of anticoagulation therapy should be recommended.

Background: This was the first prospective study to assess the safety and efficiency of MynxGrip vascular closure device (VCD) in peripheral interventions with antegrade access. Methods and Results: We enrolled 66 consecutive patients from 1 center. All patients were discharged home on the day of procedure and were observed for adverse events at 1 and 30 days of follow-up. No major complications were observed. The rate of minor complications (conversion to manual or mechanical compression) was 7.6%. Postdischarge, 3% of patients experienced minor complications—small abscess, ipsilateral deep vein thrombosis. In 1 patient, a second VCD was deployed after device failure. The derived device failure rate was 5.9%. No patients required hospitalization. No late bleeding and no hematomas >6 cm were noted. The mean time to discharge was 4 hours and 5 minutes. Conclusion: The MynxGrip was safe and effective in sealing access sites after antegrade femoral artery puncture with same-day discharge.

BACKGROUND The impact of endovascular revascularization of the lower extremity arteries with atherectomy (AT) compared with percutaneous transluminal angioplasty (PTA) is still unclear. Therefore, the aim of the study was to compare long-term outcomes after percutaneous PTA and AT in patients requiring endovascular revascularization.Methods and Results:This was a single-center, retrospective registry of obstructive and symptomatic PAD patients who underwent endovascular revascularization. PTA was performed in 215 patients, and AT in 204 (Silver Hawk, EV3, n=125; CSI 360°, n=66; Pathway Medical Technologies, n=13). There were no significant between-group differences in baseline characteristics except for increased CAD, dialysis and CLI prevalence in the PTA group. Following propensity score analysis 131 well-matched pairs were included in analysis. Bail-out stenting was more frequent in the reference group (PTA, 6.1% vs. AT, 0%; P=0.004). At 6- and 12-month follow-up there were no differences in TLR between the groups (PTA, 8.3% vs. AT, 5.3%; P=0.47; and PTA, 16.7% vs. AT, 13.7%; P=0.73, respectively). The difference was in favor of AT at 24-month follow-up (PTA, 29.0% vs. AT, 16.7%; P=0.05). No difference was observed in amputation rate (PTA, 0.7% vs AT, 1.5%; P=0.62). On Kaplan-Meier analysis there were no significant differences between groups in time to TLR, amputation or death. CONCLUSIONS AT was associated with lower risk of TLR, and this should be confirmed in randomized controlled trials.

Education in the light of Platonic philosophy is seen as establishing the natural order of the soul, or forming a character by basing it on what is eternal and perfect. The educational effort constitutes a deep insight info the spiritual and moral destiny of a human. In the face of contemporary intellectual attitudes, thinking about education manifests itself in determining effective methods and powerful means to satisfy arbitrary, incommensurable and changeable goals that do not exceed their historical-empirical conditioning. Intellectual attractiveness and the diversity of theoretical systems with logically constructed reasons is seen as an obvious, necessary and unproblematic answer to the question about education. However, that answer will be contested in this work.

Background: Novel sirolimus eluting stents (SES) have shown non-inferior clinical outcomes when compared to everolimus eluting stents (EES), however only limited preclinical data have been published. Therefore, we evaluate vascular response of a new generation biodegradable polymer SES (BP-SES: Alex Plus, Balton) and fluoropolymer EES (EES: Xience Pro, Abbott) in the porcine coronary restenosis model. Methods: A total of 40 stents were implanted with 120% overstretch in coronaries of 17 domestic swine: 16 BP-SES, 16 EES and 8 bare metal controls (BMS). Following 28 and 90 days, coronary angiography and optical coherence tomography (OCT) was performed, animals sacrificed and stented segments harvested for pathological evaluation. Results: At 28 days neointimal thickness in OCT was lowest in the BP-SES when compared to EES and BMS (0.18 ± 0.1 vs. 0.39 ± 0.1 vs. 0.34 ± 0.2 mm, respectively; p = 0.04). There was no difference in the proportion of malapposed or uncovered struts, although protruding covered struts were more common in BP-SES (14.8 ± 10% vs. 4.1 ± 4% vs. 3.7 ± 6%; p = 0.03). In pathology, the lowest neointimal thickness was confirmed in BP-SES (p < 0.05). The inflammation score was significantly lower in BP-SES and EES when compared to BMS (0.24 ± 0.1 vs. 0.4 ± 0.1 vs. 0.77 ± 0.4; p < 0.01) whilst EES and BP-SES had higher fibrin scores than BMS (1.2 ± 0.4 vs. 1.3 ± 0.3 vs. 0.17 ± 0.2; p < 0.01). At 90 days neointimal coverage and thickness in OCT was comparable between groups and healing in histopathology was complete. Conclusions: New generation, BP-SES show similar vascular healing and biocompatibility profile with marginally higher degree of restenosis inhibition, when compared to fluoropolymer EES in the porcine coronary restenosis model.

Objective The aim of the study was to assess safety and feasibility of one-day early discharge (ODD) after endovascular revascularization (ER) of lower extremities in elderly. Background Safety and feasibility of ODD after ER have never been investigated in the elderly, despite the PAD rate has been rising in well-developed countries as their populations are getting older. Methods The consecutive data of 477 patients after ER who were intended to ODD were reviewed. The ER procedure (balloon angioplasty, atherectomy, stenting) was performed due to significant, angiographically confirmed arterial stenosis with at least Rutheford III claudication. The population was divided into two groups: ≥70 years old (y. o.) in which were 235 patients and 220 patients

Objective The aim of the study was to analyze the pattern of leptin and orexin A plasma levels in patients with the restrictive type of anorexia nervosa (AN-R), during the course of treatment. Thirty females with AN-R, aged 18.0 ± 1.6 years (mean ± SD), range of 15.5–21.0 years, were investigated before and after 2, 3, and 6 months of treatment, which included a normocaloric diet and cognitive–behavioral psychotherapy. The control group consisted of 20 age-matched, healthy control females. Results Before the therapy, both leptin and orexin A plasma levels were significantly lower than in the control group and were negatively correlated. During treatment, leptin levels increased and, after 6 months, showed a correlation with body mass index (BMI). Orexin A levels showed a further decrease during treatment, with no correlation with BMI. Conclusions The results corroborate those of other researchers showing a decrease of leptin levels in patients with AN-R and its increase with body mass increment. They may also suggest a possible relationship between leptin and orexin A plasma level patterns in such patients.

This study has reported 10-year clinical follow-up of patients enrolled in the prospective, randomized LE MANS (Left Main Stenting) trial.The very long-term outcome after left main stenting in comparison with surgical revascularization remains unknown.In this prospective, multicenter trial, we randomly assigned 105 patients with unprotected left main coronary artery stenosis with low and medium complexity of coexisting coronary artery disease according to SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) score to percutaneous coronary intervention (PCI) with stenting (n = 52) or coronary artery bypass grafting (CABG) (n = 53). Drug-eluting stents were implanted in 35%, whereas arterial grafts to the left anterior descending artery were utilized in 81%. Currently, the mean long-term follow-up was collected at 9.8 ± 1.0 years. Follow up for all-cause mortality is complete, whereas the incidence of major adverse cardiovascular and cerebral events (MACCE) was reported from 90% of patients. Ambulatory follow-up was completed in 46 (43.9%) patients.At 10 years, there was a trend toward higher ejection fraction in stenting when compared with surgery (54.9 ± 8.3% vs. 49.8 ± 10.3%; p = 0.07). The mortality (21.6% vs. 30.2%; p = 0.41) and MACCE (51.1% vs. 64.4%; p = 0.28) were statistically not different between groups; however, numerically the difference was in favor of stenting. Similarly, there was no difference in the occurrence of myocardial infarction (8.7 vs. 10.4%; p = 0.62), stroke (4.3 vs. 6.3%; p = 0.68), and repeated revascularization rates (26.1% vs. 31.3%; p = 0.64). The probability of very long-term survival up to 14 years was comparable between PCI and CABG (74.2% vs. 67.5%; p = 0.34; hazard ratio: 1.45, 95% confidence interval: 0.67 to 3.13); however, there was a trend toward higher MACCE-free survival in the PCI group (34.7% vs. 22.1%; p = 0.06; hazard ratio: 1.71, 95% confidence interval: 0.97 to 2.99).In patients with unprotected left main coronary artery stenosis with low and medium complexity of coexisting coronary artery disease, stenting offers numerically, but statistically nonsignificant, favorable long-term outcome up to 10 years in terms of safety and efficacy outcome measures, therefore, constitutes an alternative therapy for CABG.

There is limited comparative clinical data regarding the safety and efficacy profile of paclitaxel delivery via balloon versus stent-polymer matrix. In this study, we aimed to compare the clinical and angiographic results of two different methods of paclitaxel delivery among patients undergoing percutaneous coronary intervention (PCI) for single de novo coronary lesions.A total of 202 patients undergoing PCI due to symptomatic heart disease and at least one significant coronary artery lesion were prospectively enrolled in a multicenter non-inferiority trial. Eligible patients were randomized to a revascularization with either a paclitaxel eluting stent (PES = Coroflex Please, B.Braun) or a bare metal stent (BMS) followed by a paclitaxel coated balloon (PCB) dilation (BMS = Coroflex + PCB = Sequent Please, B.Braun). Clinical follow-up was obtained at 9 months in all patients, whereas angiographic in a subset of 94 (46.5%) patients.The baseline characteristics were well balanced between groups. At 9 months, the primary endpoint of in-stent late lumen loss in BMS + PCB was comparable and non-inferior to PES (0.21 ± 0.5 vs. 0.30 ± 0.7 mm, respectively. P(non-inf) 0.05). At 9 months, the incidence of MACE (7.0 vs. 6.9%, HR = 1, 95%CI: 0.3-2.8; P = 0.99), comprising the occurrence of myocardial infarction (4.9 vs. 3.0%, HR = 1.62, 95%CI: 0.4-6.5; P = 0.32), target lesion revascularization (6.9 vs. 5.0%, HR = 1.42, 95%CI: 0.4-4.4; p = 0.54) and stent thrombosis (4.9 vs. 3.0%, HR = 2.01, 95%CI: 0.5-7.4; P = 0.74) was comparable between BMS + PCB and PES, respectively. In the BMS + PCB group, thrombosis tended to occur within 30 days (3.9 vs. 1.0%; P = 0.38).Paclitaxel delivery via drug coated balloon or polymer-stent matrix achieved comparable angiographic and clinical results among patients with de novo coronary lesions. BMS + PCB revascularization was associated with a higher rate of stent thrombosis when compared to newer generation drug eluting stents, therefore, should be recommended as a bail-out for PCB alone angioplasty.

Percutaneous coronary intervention (PCI) utilizing drug-eluting stents is becoming a very common revascularization technique in the dialysis cohort; therefore, we sought to identify the impact of dialysis on outcomes in this group of patients. This is a multicenter registry comparing results of 290 patients (186 with normal kidney function, 104 on dialysis) who underwent PCI with exclusive use of paclitaxel-eluting TAXUS stent. The primary endpoint was an assessment of major adverse cardiac events (MACE) at 1- and 2-year observation. Mean follow-up was 23.3 ± 6.1 months. Results at 12 months showed: MACE 11.8% vs. 7.7% (P = not significant [ns]), composite major adverse cardiac and cerebrovascular events (MACCE) 12.4% vs. 11.5% (P = ns), all-cause death 2.7% vs. 8.6% (P 0.05), cardiac death 2.7% vs. 1.9% (P = ns), target vessel revascularization (TVR) 9.1% vs. 6.7% (P = ns), acute myocardial infarction (AMI) 3.8% vs. 2.9% (P = ns), cerebrovascular events (CVA) 0.5% vs. 1.0% (P = ns); and results at 24 months showed: MACE 17.7% vs. 18.3% (P = ns), MACCE 21.5% vs. 26.0% (P = ns), all-cause death 4.3% vs. 14.4% (P 0.01), cardiac death 3.2% vs. 1.9% (P = ns), TVR 14.0% vs. 16.3% (P = ns), AMI 5.4% vs. 5.8% (P = ns), CVA 3.2% vs. 2.9% (P = ns) for non-end-stage renal disease (ESRD) and dialysis group, respectively. Prior coronary artery bypass graft (CABG) was found to be single risk factor for MACE, TVR, and MACCE in patients with ESRD, while dialysis and prior CABG were found to be single risk factors for death in the entire population. PCI with TAXUS is a feasible procedure and presents promising results in dialysis-dependent patients.

Background: The prevalence of diabetes has increased significantly in well-developed countries during the last decade and it continues to grow. Diabetes increases the risk of restenosis in patients treated percutaneously for peripheral artery disease. The present study sought to compare outcomes of atherectomy treatment in diabetic (DM) vs. non-diabetic (nDM) patients suffering from peripheral artery disease. Method: Between 2008 and 2012, 204 revascularization atherectomy procedures were performed on arteries of the lower extremities. The endpoints included target lesion revascularization (TLR), amputation and death. The type of atherectomy (excisional-soft plaque, orbital-calcified plaque, with active aspiration — with a thrombus) was left to operator discretion. Results: This study contains 132 DM (66% male, age 68 ± 11.2 years) and 72 nDM (63% male, age 75 ± 11.3 years) subjects. DM were younger but had a higher prevalence of coronary artery disease (DM: 91% vs. nDM: 62%, p < 0.0001) and end-stage renal disease (DM: 22% vs. nDM: 2.5%, p < 0.0001). There were no differences in critical limb ischemia between the groups (DM: 21% vs. nDM: 12%, p = = 0.13). Mean time of follow-up was 384 and 411 days in DM and nDM, respectively (p = 0.43). There were no significant differences in TLR (DM: 15.2% vs. nDM: 22.2%, p = 0.249), amputations (DM: 3.0% vs. nDM: 1.5%, p = NS) or death rates (DM: 2.2% vs. nDM: 2.7%, p = NS). Kaplan-Mayer analysis showed no significant differences between the groups in the time to TLR, amputation or death. Conclusions: Plaque modification with adjusted atherectomy appears to have similar outcomes in diabetic as well as in non-diabetic patients. Nonetheless, a randomized study would be warranted to confirm the findings of the current study.

Orthorexia nervosa (Greek: ortho--correct, right; orexis--appetite, desire) is a term introduced in 1997 by the American doctor Steven Bratman and is defined as a pathological fixation with righteous and healthy eating. Clear classification criteria oforthorexia have not been developed yet and there has been an on-going discussion whether it belongs to the group of eating disorders or the obsessive-compulsive disorders.The aim of this paper is to summarise briefly the current state of knowledge regarding orthorexia and to point out the difficulties connected with an attempt to classify it in a given disorders group as well as with the attempt to establish the classification criteria.Despite the fact that the problem of orthorexia has been signalled in the Polish media, it has neither been discussed nor published in the Polish medical literature yet. Orthorexia starts when a diet becomes an escape from life--everyday activities are dominated by planning, buying and preparing "proper" meals. Each departure from this regime causes anxiety and guilty conscience and leads to even further tightening of the dietary habits. According to Bratmann, orthorexia is connected with an illusory feeling of safety (preventing from diseases), the urge to exercise a full control over one's life (elimination of the unpredictable), "a hidden conformism" (eating philosophy helps in a subconscious way to achieve a culturally accepted model of a beautiful body), a search for spirituality and identity, and a desire for self-deprivation.The arguments presented in this paper substantiate the expediency of implementing the epidemiological studies which will show the scale of the problem, its prevalence and conditionings. Data obtained in this way should facilitate the verification of classification criteria and will also help to formulate the diagnostic criteria of orthorexia.
