Aim. To analyze and generalize inhospital outcomes of myocardial revascularization in patients with coronary artery calcification.Material and methods. The primary selection yielded 470 publications, including 354 from the Pubmed database in English and 116 from the E-library database in Russian. Thirteen studies were selected that met the search criteria. Among them, 5 studies were for coronary artery bypass grafting (n=932) and 8 for endovascular intervention (n=5758). The endpoints were 30-day mortality and perioperative myocardial infarction (PMI).Results. PMI incidence in patients with coronary artery calcification in percutaneous coronary intervention using atherectomy techniques is 4,4%, while inhospital mortality - 0,9%. PMI incidence in coronary artery bypass grafting using complex coronary interventions in this group of patients is 2,6%, while inhospital mortality - 0,7%.Conclusion. Myocardial revascularization in patients with coronary calcification can be performed by endovascular and open approaches using advanced coronary surgery techniques. Inhospital outcomes seem satisfactory. Conclusions about the advantages of one method or another require comparative studies.

Published: December 2024

One of the known potential complications associated with endovascular closure of the patent foramen ovale (PFO) is de novo atrial fibrillation (AF).Aim. To assess the risk factors and incidence of de novo AF in patients who underwent endovascular PFO closure.Material and methods. The data of 276 patients who underwent endovascular PFO closure for the period from 2020 to 2023 at the Chazov National Medical Research Center of Cardiology were analyzed. All patients underwent examinations in accordance with clinical guidelines. De novo AF in the postoperative period was assessed by Holter monitoring, while 1, 6 and 12 months after the intervention — by electrocardiographic recording. Based on univariate regression analysis, risk factors associated with de novo AF were identified.Results. De novo AF in the postoperative period was registered in 2 patients. One month after the intervention, AF episodes were diagnosed in 6 patients. After 6 months, AF detected earlier persisted in 3 patients,and there were 3 new cases. Twelve months after the intervention, AF was recorded in 2 patients. According to regression analysis, the following parameters were associated with de novo AF: age ≥52,0 years (hazard ratio (HR) 6,22; 95% confidence interval (CI): 1,51-25,56), body mass index ≥28,07 kg/m2 (HR 8,48; 95% CI: 1,72-41,73), CHARGE-AF score ≥0,56 (HR 4,59; 95% CI: 1,12-18,82), left atrial size ≥4,00 cm (HR 19,56; 95% CI: 2,10-181,88), LAVi ≥34 ml/m2 (HR 45,67; 95% CI: 5,46-381,83) according to echocardiography.Conclusion. Echocardiographic signs of left atrial and left ventricular dilation were significantly associated with a high risk of de novo AF in the immediate and longterm periods after endovascular PFO closure.

Abstract
Changes in breathing during pranayama (yoga breathwork) are usually inferred from practice guidelines in traditional texts or contemporary writings. These changes point to understanding the effects of pranayama and indicate applications of pranayama in health. Previously, a pilot study on a single participant suggested that each pranayama changes breathing uniquely. To extend this research in the present study, 23 yoga practitioners (mean age 28.1 ± 3.8; 12 men, 11 women) who were able to practice the pranayama consistently were each studied in a 48-minute session with five pranayama practices—(1) alternate-nostril yoga breathing, (2) bellows yoga breathing, (3) bumblebee yoga breathing, (4) high-frequency yoga breathing, and (5) hissing yoga breathing—as well as (6) breath awareness for 3 minutes each. From strain gauge–recorded respiratory movements, the breath frequency, depth/amplitude of breathing, and inspiration:expiration were obtained. Compared to the baseline, breath rate increased during high-frequency breathing (373.3%) and decreased during bumblebee breathing (75.3%), hissing breathing (63.0%), and alternate-nostril breathing (55.3 %). The depth of breathing increased in alternate-nostril breathing (141.0%), bellows breathing (136.0%), bumblebee breathing (307%), high-frequency breathing (275.0%), and hissing breathing (95.0%). The inspiration:expiration increased in high-frequency breathing (177.0%) and decreased in bumblebee breathing (74.3%) and alternate-nostril breathing (39.0%). There were no changes during breath awareness. The changes in breathing (although limited by the small sample size) support previous reports of high-frequency breathing as being activating while enhancing attention, and of bumblebee and alternate-nostril breathing (hissing and bellows breathing to a lesser extent) as calming, with increased vagus nerve activity.

Published: December 2024

The purpose of this pilot study was to test the efficacy of a novel self-help program called Attention training (AT) based on the mindfulness-acceptance principles in a sample of dysphoric students. We tried to determine if the program: a) contributed to immediate and follow-up changes in the presumed components and mechanisms of mindfulness-acceptance - psychological flexibility, attention control (switching and updating), and rumination; b) was followed by a reduction in dysphoric symptoms; c) had different effects depending on a different order of exercises within AT. The final sample consists of 18 students from the University of Novi Sad, 19-29 years old with mild and moderate depression (selected through pre-screening procedure). Data were collected at 4 measurement occasions: before the first group meeting (pretest), right after completion of all exercises (posttest), and two follow-ups - one and three months post-treatment. AT consisted of 8 small-group, weekly meetings (up to 5 persons and < 90 minutes of overall therapist support). Participants listened to the audio-recorded exercises that targeted the somatic, emotional, and cognitive domains. The sample was randomly split into two groups with a different order of the emotional and cognitive exercises. We found that AT, as a self-help intervention, can potentially lead to improvements in the mindfulness components and mechanisms, even though an increase in the depressive symptoms was noticed. Different explanations were provided for such findings, including suggestions for further optimization of the program and recommendations for further research.

The present study aimed to replicate, implement, and evaluate the effectiveness of The Third Half, a multi-component psychoeducational program in doctoral students. To address the limitations of the pilot study, we conducted a non-randomized controlled study using a repeated measures pre-post design with a total of 97 participants (Mage = 32.5; SD = 8.23), of whom 26 participated in the experimental group. Results showed that Third Half program participants reported significant decreases in indicators of negative affect (F = 4.01; p = .04) and anxiety (F = 4.95; p = .02) compared to the general control group; in the matched sample analysis (n = 20) significant decreases were found in indicators of negative affect (F = 4.72; p = .03), anxiety (F = 4.09; p < .001), and depression (F = 4.95; p = .03). It is concluded that the Third Half program is an effective and implementable psychoeducational program to improve the skills of early-career researchers in wellness management.
A Semi-Analytical Model of a Hydraulically Fractured Horizontal Well with Pre-Darcy Flow and Stimulated Reservoir Volume in a Radial Composite Shale Reservoir

Summary
Due to the low porosity and permeability of the shale matrix, multi-fractured horizontal well (MFHW) is one of the most well-known technologies to promote the withdrawal of shale oil. It is a great challenge to characterize the flow behavior by coupling pre-Darcy flow in pores of the shale matrix and Darcy flow inside fractures, particularly in the radial composite shale reservoir with stimulated reservoir volume (SRV). Because the semi-analytical method can contribute to revealing the flow mechanism of the MFHW, the approach to efficiently obtain a suitable and exact semi-analytical solution becomes a key issue. In this work, to couple the modified point-source solution of the shale matrix with the numerical solution of fractures,we developed a semi-analytical solution to analyze the impact of pre-Darcy flow and SRV properties on the pressure behavior of the MFHW. Moreover, we used a local grid refinement method to verify the accuracy of the newly developed semi-analytical solution. The results show that the radial flow regime in the dimensionless pressure derivative will obviously disappear due to the pre-Darcy flow. Pre-Darcy flow in the SRV zone is adverse to the late production of the MFHW after the pseudolinear flow regime, while pre-Darcy flow in the unstimulated reservoir volume (USRV) zone is beneficial to increase the production during the regional interporosity flow regime. Meanwhile, the “groove” can be recognized from the pressure derivative curves, which mainly depend on the mobility ratio and the storage capacity ratio. In addition, due to the uneven distribution of fractures, the pressure derivative during the pseudoradial flow regime significantly deviates from 1/(2N).
