Endovascular methods are leading in the treatment of patients with acute coronary syndrome (ACS). Transradial access (TRA) is traditionally used, but there are some disadvantages. Distal transradial access (dTRA) is an alternative to conventional TRA, but its outcomes in patients with ACS are controversial.Aim. To evaluate the safety and efficacy of vascular accesses, as well as in-hospital outcomes of treatment of patients with ACS using conventional TRA versus dTRA.Material and methods. This single-center, prospective, randomized study included 264 patients with ACS, which were divided into 2 groups: group 1 (n=132) — dTRA, group 2 (n=132) — TRA. The groups were comparable in the initial clinical, laboratory and angiographic characteristics.Results. During percutaneous coronary intervention, 240 drug-eluting stents were implanted in 184 patients. In 10 patients, access was converted: from dTRA to TRA in 2,3% (n=3), from dTRA to femoral  — 3,0% (n=4), from dTRA to femoral in 2,3% (n=3). The mean puncture time was 125,1±11,9 s in group 1 and 58,8±8,2 s in group 2 (p<0,00005). There was no difference in the total intervention duration as follows: 30,5±7,1 min and 29,4±4,6 min (p=0,1428), respectively. The time to hemostasis was significantly higher in the TRA group: 354,2±28,1 vs 125,4±15,3 min in group 1 (p<0,00005). When using dTRA, a lower incidence of hematomas (0,8 (n=1) vs 7,0% (n=9) (p=0,019)), spasm (5,6 (n=7) vs 13,2% (n=17) (p=0,039)) and radial artery occlusion (0,8 (n=1) vs 6,2% (n=8) (p=0,036)). The number of major adverse cardiac events (MACE) in both groups was comparable: 10,4% (n=13) and 10,1% (n=13) in group 1 and 2, respectively (p=0,932).Conclusion. The use of dTRA does not increase the total procedure duration compared to conventional TRA. The complication rate was comparable in both study groups. When dTRA was used, the incidence of local complications was significantly lower compared to conventional TRA. Thus, dTRA can be an alternative to conventional TRA, but large randomized trials are required for final conclusions.

The objective: was to evaluate the efficacy of the first line chemotherapy in patients with metastatic triple negative breast cancer (TNBC). Materials and methods. Open randomized study was performed including 122 patients with metastatic TNBC. The efficacy and safety of the first line chemotherapy of regimens АТ (n=59) – group 1, patients received doxorubicine 60 мг/м2 and paclitaxel 175 мг/м2 and ТР (n=63) – group 2, patients received paclitaxel 175 мг/м2 and carboplatin AUC 5 were evaluated. Results. The median duration of response was 9.5 months (4.5–13.25 months) in patients received AT regimen and 8.5 months (4.7–12.25 months), in TP regimen; no statistically significant differences were observed, р=0.836. The median progression free survival was 7 months (95% CI 5–26 months) in group 1 and 7.5 months (95% CI 6–35 months) in group 2, p=0.85. Both chemotherapy regimens (AT and TP) had mild or moderate toxicity profiles (grade 1 or 2 in most patients). No significant difference in gastrointestinal toxicity was observed. The incidence of grade 3–4 neutropenia was higher in patients of group 2 (TP regimen): 42.8% versus 27% (р<0.05). Conclusions. Both regimens of chemotherapy (AT and TP) are appropriate to use in the first line setting in patients with metastatic TNBC. Key words: metastatic triple negative breast cancer, chemotherapy, progression free survival, chemotherapy toxicity.

Abstract Purpose The main purpose and research question of the study are to compare the efficacy of high-security closed versus open devices for human oocytes’ vitrification. Methods A prospective randomized study was conducted. A total of 737 patients attending the Infertility and IVF Unit at S.Orsola University Hospital (Italy) between October 2015 and April 2020 were randomly assigned to two groups. A total of 368 patients were assigned to group 1 (High-Security Vitrification™ - HSV) and 369 to group 2 (Cryotop® open system). Oocyte survival, fertilization, cleavage, pregnancy, implantation, and miscarriage rate were compared between the two groups. Results No statistically significant differences were observed on survival rate (70.3% vs. 73.3%), fertilization rate (70.8% vs. 74.9%), cleavage rate (90.6% vs. 90.3%), pregnancy/transfer ratio (32.0% vs. 31.8%), implantation rate (19.7% vs. 19.9%), nor miscarriage rates (22.1% vs. 21.5%) between the two groups. Women’s mean age in group 1 (36.18 ± 3.92) and group 2 (35.88 ± 3.88) was not significantly different (P = .297). A total of 4029 oocytes were vitrified (1980 and 2049 in groups 1 and 2 respectively). A total of 2564 were warmed (1469 and 1095 in groups 1 and 2 respectively). A total of 1386 morphologically eligible oocytes were inseminated by intracytoplasmic sperm injection (792 and 594 respectively, P = .304). Conclusions The present study shows that the replacement of the open vitrification system by a closed one has no impact on in vitro and in vivo survival, development, pregnancy and implantation rate. Furthermore, to ensure safety, especially during the current COVID-19 pandemic, the use of the closed device eliminates the potential samples’ contamination during vitrification and storage.

Aim. To compare the microleakage in class II composite restorations without a liner/with resin modified glass ionomer and flowable composite liner.Method. Forty standardized MO cavities were prepared on human permanent mandibular molars extracted for periodontal reasons and then divided into 4 groups of ten specimens. The cavity preparations were etched, rinsed, blot dried, and light cured and Adper Single Bond 2 is applied. Group 1 is restored with Filtek P60 packable composite in 2 mm oblique increments. Group 2 is precure group where 1 mm Filtek Z350 flowable liner is applied and light cured for 20 sec. Group 3 is the same as Group 2, but the liner was cocured with packable composite. In Group 4, 1 mm RMGIC, Fuji Lining LC is applied and cured for 20 sec. All the teeth were restored as in Group 1. The specimens were coated with nail varnish leaving 1 mm around the restoration, subjected to thermocycling, basic fuchsin dye penetration, sectioned mesiodistally, and observed under a stereomicroscope.Results. The mean leakage scores of the individual study groups were Group 1 (33.40), Group 2 (7.85), Group 3 (16.40), and Group 4 (24.35). Group 1 without a liner showed maximum leakage. Flowable composite liner precured was the best.

Aim: To compare surgical parameters and visual outcomes of coaxial microincision cataract surgery (MICS) with standard phacoemulsification. Methods: A prospective randomized study was conducted on 60 eyes of 60 patients with age-related uncomplicated cataract who underwent: standard phacoemulsification surgery (30 eyes) i.e., Group 1, or coaxial MICS (30 eyes) i.e., Group 2. Intraoperative parameters were mean effective phacoemulsification power (EPP), effective phacoemulsification time (EPT), and total volume of balanced salt solution (BSS) used. Best-corrected visual acuity (BCVA) and surgically induced astigmatism (SIA) were evaluated pre- and postoperatively. Results: Mean BCVA at 6 weeks was 0.04 ± 0.07 in Group 1 and 0.05 ± 0.08 in Group 2. No significant difference was observed in SIA between the two groups. Mean EPT was 29.80 ± 3.67 seconds in Group 1 and 31.93 ± 4.08 seconds in Group 2. The mean total EPP in Group 1 was 35.77 ± 5.17%, whereas it was 33.70 ± 3.05% in Group 2. There was a significant statistical difference between mean EPP and EPT in the two groups. Mean total BSS volume used in Group 1 was 128.83 ± 19.81 ml, whereas it was 139.33 ± 13.57 ml in Group 2. Conclusion: Although EPT and BSS volume used were significantly higher in coaxial MICS, the postoperative results of the two techniques were comparable.

Background: To compare cranial 15º angulation of Veres needle to classic Veress needle entry in closed laparoscopic entry in obese patients. Method: Patients with BMI index>30 were divided into two groups. Initial entry into the abdomen in Group 1 (n=29) was performed with the intraumbilical insertion of Veress needle in 90o angle relative to the horizontal plane. In Group 2 (n=31) the Veress needle was placed intraumbilically in a cranial direction, the tip of the needle towards the thoracic cavity, with an angle of 15o to the horizontal plane. Two groups were compared with respect of the operative outcomes. Results: In Group 2, the mean number of Veress needle entries attempt was significantly lower than Group 1 (p=0.01). Time to insertion of the Veress needle was found to be significantly shorter in Group 2 than in Group 1 (p<0.001). While entry failure occurred in 3 patients in Group 1 (10.3%), no failures were monitored in any patients in Group 2 (p= 0.01). Complication rate was significantly lower in Group 2 than in Group 1 (p= 0.03). Conclusion: Placement of Veress needle intraumbilically in a cranial direction at 15°angle to the horizontal plane increases entry success and reduces complications.

The purpose of this study was to evaluate the effect of the use of the combined auxiliaries of oral hygiene with whitening agents on the micro-hardness and micro-morphology of dental enamel. Materials and Methods. 40 human incisors were used and sectioned to obtain 4x4mm samples and divided into four study groups. Group 1: Electric brushing with Toothpaste (BTP); Group 2: Electric brushing with Toothpaste+mouthwash (BTP+MW); Group 3: Electric brushing with Toothpaste+whitening pen (BTP+WP); Group 4: Electric brushing with Toothpaste+mouth wash+whitening pen (BTP+MW+WP). Samples were submitted toVickers micro-hardness test and visualized using scanning electron microscopy (SEM). Results. All groups, with the exception of group 1, showed a decrease in micro-hardness values after applying the treatments (p<0.05). Likewise, when comparing the values after the treatments between the groups, significant statistical differences were found in all of comparisons except for those of groups 2 and 4. SEM images showed changes in the morphology in all the study groups with the exception of group 1. Conclusion. Significant changes such as decrease in micro-hardness as well as in the topography of the enamel surface such as elevations, craters, porosities and etching patterns were founded after the use of the combination of auxiliaries of oral hygiene with whitening agents.

Introduction: Pulmonary vein (PV) isolation forms the cornerstone of any ablation procedure for atrial fibrillation (AF). There is, however, no uniform strategy how to detect and target left atrial (LA) arrhythmogenic substrate outside the PV antra. Fibrosis that corresponds well to LA low-voltage areas (LVAs) seems to play a key role in AF arrhythmogenesis and might therefore be a suitable target for additional substrate modification (SM). Objective: The purpose of this prospective randomized study was to compare a novel technique for SM based on ablation of potentially arrhythmogenic LA LVAs with a standard approach consisting of empiric LA linear ablation. Methods: Patients (pts) with symptomatic paroxysmal or persistent AF were randomized to standard (group 1) or personalized (group 2) SM. Circumferential PV isolation was the primary step in both groups. In group 1, pre-defined linear lesions were applied at the LA roof and bottom, respectively, and at the mitral isthmus only in pts with persistent AF. In group 2, targets for SM (i.e. LVAs) were identified by detailed bipolar voltage mapping (BVM) during sinus rhythm irrespective of AF type. Peak-to-peak electrogram amplitudes were defined as “normal” (> 0.5 mV), as “low voltages” (0.2 to 0.5 mV), or as “scar” (< 0.2 mV). LVAs were targeted by tissue homogenization and / or strategic linear lesions. The primary endpoint was freedom from any atrial arrhythmia (i.e. AF, atrial flutter, or atrial tachycardia) > 30 seconds off antiarrhythmic drugs on serial 7-d-Holter ECG recordings after a follow-up period of 12 months. Results: In total, 124 ablation-naïve pts (mean age 63 ± 9 years, 62 % male, 49 % with persistent AF) were enrolled in this study. LVAs were present in 18 % of pts with paroxysmal and in 41 % of pts with persistent AF (p<0.05). At the end of the follow-up period, 25 out of 59 pts (42 %) in the conventional group were free from arrhythmia recurrence as compared to 40 out of 59 pts (68 %) in the BVM-guided group (unadjusted log rank p = 0.003). Conclusion: Personalized SM guided by endocardial BVM is associated with a higher success rate compared to a conventional approach applying empirical SM based on AF phenotype.

OBJECTIVE: To investigate the value of leaving seizure-free patients on low-dose medication. METHOD: This was an exploratory prospective randomized study conducted at our University Hospital. We evaluated the frequency of seizure recurrence and its risk factors following complete or partial antiepileptic drug (AED) withdrawal in seizure free patients for at least two years with focal, secondarily generalized and undetermined generalized epilepsies. For this reason, patients were divided into two groups: Group 1 (complete AED withdrawal), and Group 2 (partial AED withdrawal). Partial AED withdrawal was established as a reduction of 50% of the initial dose. Medication was tapered off slowly on both groups. Follow-up period was 24 months. RESULTS: Ninety-four patients were followed up: 45 were assigned to complete (Group 1) AED withdrawal and 49 to partial (Group 2) AED withdrawal. Seizure recurrence frequency after two years follow-up were 34.04% in group 1 and 32.69% in Group 2. Survival analysis showed that the probability of remaining seizure free at 6, 12, 18 and 24 months after randomization did not differ between the two groups (p = 0.8). Group 1: 0.89, 0.80, 0.71 and 0.69; group 2: 0.86, 0.82, 0.75 and 0.71. The analysis of risk factors for seizure recurrence showed that more than 10 seizures prior to seizure control was a significant predictive factor for recurrence after AED withdrawal (hazard ratio = 2.73). CONCLUSION: Leaving seizure free patients on low AED dose did not reduce the risk for seizure recurrence. That is, once the decision of AED withdrawal has been established, it should be complete.

To improve healing of pressure ulcer wounds, it is important to optimize the conditions of the area surrounding the wound. Negative pressure wound therapy (NPWT) promotes wound healing, however, the removal of NPWT can cause pain or focal bleeding, delaying wound healing or causing infection. In this study, we reviewed the efficacy of the lipidocolloid non-adherent dressing (Urgotul®) as a wound contact layer. A total of 38 patients from the same facility who applied NPWT from April 2016 to October 2019 were included and divided into two groups; NPWT with the lipidocolloid non-adherent dressing (group 1, experimental group, 19 patients) and NPWT only (group 2, control group, 19 patients). The condition of the wound was examined prior to NPWT application, at one week, and again at three weeks after application. No significant differences were found between groups for general characteristics, bacterial culture or photo analysis. However, when comparing groups based on the time of examination, there was a significant reduction of the wound size in group 1 (p = 0.001) but not in group 2 (p = 0.082). Therefore, the current study finds that using the lipidocolloid non-adherent dressing as a wound contact layer in NPWT stimulates healing by shrinking the size of the pressure ulcer wound.
