Aim. To evaluate remote outcomes of transcatheter aortic valve implantation (TAVI), including overall survival, freedom from cardiovascular death, permanent pacemaker implantation, and repeat valve replacement.Material and methods. This retrospective observational study included 535 patients who underwent TAVI from April 2015 to January 2024. Patients who underwent TAVI for moderate aortic stenosis or severe aortic valve regurgitation (n=35) were excluded from the analysis. A total of 500 patients were included in the final analysis. Males accounted for 40,8%. Most patients had intermediate EuroSCORE II risk (5,2%), as well as low STS-PROM score risk (2,9%). The median follow-up period was 2,2 (0,6;4,1) years.Results. Overall patient survival was 94%, 88%, 86%, and 58% at 1, 3, 5, and 8 years, respectively. Freedom from cardiovascular death was 97%, 90%, 78%, and 61% at 1, 3, 5, and 8 years, respectively. The cumulative freedom from permanent pacemaker implantation over the entire follow-up period was 89,4%, and from repeat pacemaker replacement — 98,8%. The factors influencing the long-term all-cause mortality were male sex, smoking, cancer, and left ventricular mass index. The only independent predictor of cardiovascular death was the STS-PROM score.Conclusion. Our experience demonstrates satisfactory long-term outcomes of transcatheter aortic valve implantation in patients with severe aortic stenosis in terms of overall survival, cardiovascular death, permanent pacemaker implantation, and repeat pacemaker replacement. Independent predictors of all-cause death were male sex, smoking, cancer, and left ventricular mass index. The only independent predictor of cardiovascular death in the long-term period was the STS-PROM score.

Aim. To study the prevalence and risk factors (RF) for hospital-acquired pneumonia (HAP) after on-pump cardiac surgery in a modern cohort of patients.Material and methods. This retrospective analysis of the medical records of cardiovascular surgery patients, operated on in the period from January 1, 2022 to December 31, 2022. The study consistently included 417 patients who underwent on-pump cardiac surgery. The incidence and timing of HAP development were assessed. The influence of the main demographic, clinical, and perioperative factors on HAP risk was studied.Results. The pneumonia prevalence per year was 27,6%, including after the Frozen Elephant Trunk (FET) procedure — 32%, after coronary artery bypass grafting (CABG) — 29,5%, after combined CABG and heart valve surgery — 26,2%, after isolated valve surgery — 25,9%, after thoracic aortic hemiarch replacement — 19,5%. Pneumonia developed on the 4,6±2,9 day after surgery. The risk of pneumonia increased with atrial fibrillation (AF) before surgery (odds ratio (OR) 3,17; 95% confidence interval (CI): 1,67; 6,02, p=0,0002), on-pump duration (OR 1,01; 95% CI: 1,00; 1,01; p=0,0006), aortic cross-clamping (OR 1,01; 95% CI: 1,00; 1,01; p=0,0002) and mechanical ventilation (OR 1,03; 95% CI: 1,01; 1,05; p=0,005). Pneumonia predictors were on-pump duration ≥96 min (sensitivity 67,7%, specificity 64,6%, AUC=0,681, p=0,0006) and mechanical ventilation ≥14 h (sensitivity 63,1%, specificity 69,3%, AUC=0,641, p=0,005), as well as preoperative AF (sensitivity 61%, specificity 75%, p=0,0002).Conclusion. Preoperative AF, on-pump duration ≥96 min and mechanical ventilation ≥14 h serve as categorical and quantitative predictors of postoperative HAP in a modern cohort of patients.

Aim. To study quantitative parameters of coronary atherosclerosis, according to computed tomography coronary angiography (CTCA), and to identify their association with the level of cardiac biomarkers in patients with acute myocardial infarction (MI).Material and methods. The study included patients with newly diagnosed MI. Depending on the coronary artery (CA) stenosis, two groups were formed: 1) MI with obstructive CA ≥50% (MICAD); 2) MI with non-obstructive CA <50% (MINOCA). All patients were assessed for cardiac biomarkers and underwent CTCA.Results. The study included 31 patients as follows: MINOCA group consisted of 10 patients (5 men aged 68 (57; 79) years); MICAD group — 21 patients (13 men aged 62 (56; 68) years). When analyzing cardiac biomarker levels, a significant increase in cardiac troponin I (cTnI) levels was noted on the 4th (p=0,04) and on the 7th day (p=0,0009) in MICAD patients. A significant predominance of the volume (p=0,01) and burden (p=0,004) of low-density plaques was revealed in the MICAD group compared to MINOCA. In addition, MICAD patients had significantly increased values of the total atherosclerotic burden (p=0,01) and the total burden of the soft tissue component of plaques (p=0,04). A significant correlation was found between the plaque volume with cTnI on day 7 (ρ=0,52, p<0,05) and the plaque burden with cTnI on day 7 (ρ=0,43, p<0,05).Conclusion. According to CTCA, the soft tissue component of plaques is associated with coronary atherosclerosis severity and myocardial damage in patients with MI. Soft tissue burden is a predictor of more severe myocardial damage, according to the cardiac biomarker data.

Aim. To compare the effectiveness of the POAF, PAFAC, COM-AF, HATCH, ms2HEST and CHA2DS2-VASc scores for predicting new-onset atrial fibrillation (AF) in patients with ST-elevation myocardial infarction (STEMI) after percutaneous coronary intervention (PCI), as well as to develop novel prognostic models based on machine learning methods.Material and methods. This single-center retrospective study was conducted using data from 3449 electronic health records of patients with STEMI. Two groups of individuals were identified, the first of which included 312 (9%) patients with new-onset AF in the postoperative period of PCI, and the second — 3139 (91%) patients without cardiac arrhythmia. To predict AF, univariate and multivariate logistic regression (ULR and MLR), decision tree (DT), artificial neural networks (ANN) were used.Results. The study results showed that of the 6 analyzed scores, only 4 (mc2HEST, COM-AF, CHA2DS2-VASc and HATCH) have an acceptable prognostic potential for new-onset AF after PCI, which was documented by the AUC metrics in the ULR models developed on the basis of the sum of points of each score (AUC — 0,736, 0,731, 0,71 and 0,702, respectively). The integrative ANN model, combining the prognostic resource of 6 scores, demonstrated higher accuracy than the DT and MLR models (AUC — 0,759 vs 0,745 and 0,755, p-value<0,0001).Conclusion. Further studies aimed at improving the quality of AF prognostic models in patients with STEMI after PCI may involve searching for novel predictors characterizing severity of coronary involvement and effectiveness of its restoration, inflammatory response, myocardial electrophysiological status, etc.

Aim. To compare standard indices of myocardial perfusion scintigraphy (MPS) and quantitative indicators of myocardial dynamic single-photon emission computed tomography (SPECT) in patients with non-obstructive coronary artery disease (NOCAD).Material and methods. The study included patients with symptoms or signs of myocardial ischemia and NOCAD (<50%). All patients underwent dynamic myocardial SPECT with assessment of standard MPS indices (summed stress score (SSS), summed rest score (SRS), summed difference score (SDS)) and quantitative indicators (stress and rest myocardial blood flow (MBF), myocardial flow reserve (MFR) and stress/rest MBF difference (ΔMBF)).Results. According to MPS, 15 (26%) patients had signs of myocardial perfusion dysfunction (SSS ≥2,0). Standard MPS indices had low values as follows: SSS 0,0 (0,0; 2,0), SRS 0,0 (0,0; 0,0), SDS 0,0 (0,0; 2,0). According to dynamic myocardial SPECT, 22 (38%) patients had a reduced MFR <2,0. Quantitative indicators were characterized by greater variability compared to the MPS data as follows: stress MBF 1,34 (1,03; 1,64) ml/min/g, rest MBF 0,58 (0,42; 0,73) ml/min/g, MFR 2,42 (1,48; 2,85), ΔMBF 0,68 (0,36; 1,09). In 7 (12%) patients, ischemic myocardial changes (SSS ≥2,0) was associated with a reduced MFR <2,0, and in 28 (48%) without signs of ischemia (SSS <2,0) the MFR was within normal values ≥2,0. However, 15 (26%) had a normal radiopharmaceutical distribution and a reduced MFR, which may indicate the initial stages of microvascular dysfunction, which did not lead to myocardial ischemia.Conclusion. The dynamic SPECT allows in ~30% of cases to identify MBF and MFR disorders in NOCAD patients with normal results of standard SFM.

Published: January 2025

Background: Pulses, endowed with unique ability of nitrogen fixation constitute an important component of crop diversification and resource conservation in farming systems. Green gram [Vigna radiate], a drought resistant crop, is one of the thirteen food legumes grown in India and the third most important pulse crop after chickpea and pigeon pea It is a protein rich staple food which contains about 25 percent protein and plays a crucial role in enhancing soil fertility through biological nitrogen fixation. Sodic soils typically exhibit poor nutrient availability as essential cations are displaced by sodium ions. They significantly influence green gram productivity, posing challenges to its sustainability, with the potential for sodification extending into subsoil layers, impeding plant root development and requiring remedial action. Appropriate land configuration and nutrient management could mitigating the challenges posed by sodic soils for pulse crops. Understanding the effects of land configuration and nutrient management on its growth, yield andeconomic viability is vital for sustainable agriculture. Keeping this in view, the field experiment was conducted to study the effect of different land configuration and nutrient management for their impact on plant height, dry matter production, grain yield, haulm yield, net income andBenefit Cost ratio with nutrient uptake under sodic condition. Methods: The land configuration factor consists of the three treatments viz., flat bed, ridges and furrows and broad bed furrow system. The second factor nutrient management comprising of five treatments like 100% RDF + 1% DAP, 100% RDF + 1% MAP, 75% RDF + 2% MAP, 100% RDF + 1% MKP, 75% RDF + 2% MKP. The RDF for green gram was 25 kg N + 50 kg P2O5 + 25 kg K2O per hectare. Result: Higher plant height, dry matter production, grain and haulm yield, protein yield, economic and nutrient uptake was recorded in broad bed furrow over farmer’s practice of flatbed method. N 4 - 100% RDF + 1% MKP foliar spray twice at (plant height, dry matter production, grain and haulm yield, protein yield, economic and nutrient uptake ) were observed than farmer’s practice. Hence, Broad bed furrow and nutrient management practice of 100% RDF + 1% MKP has the potential to enhance the productivity green gram under sodic condition.

Published: January 2025

This article aims to explore the shifting of livelihood (nafqa) responsibilities from husbands to wives in the contemporary context while looking at Muslim community’s reading on relevant Qur’an verses and hadith. Wives who work as migrant workers tend to serve as the main breadwinner in providing income in a household, including those from Kediri and Tulungagung, East Java. Livelihood itself is a common topic in the Islamic law discussion, mainly about who provide for whom and its quantity criteria. Based on this problem, we portray the phenomenon and then present a reading of relevant Qur’anic verses and hadith within the community. The qualitative method was used by conducting interviews with husbands situated in that specific type of household. Data collection was also carried out by a review of relevant verses and hadith on family life followed by analytical approach using content analysis to identify how they are perceived by Muslim community. This study offers insights into Islamic family law in contemporary society, linking religious teachings to modern realities and providing a deeper understanding of this complex issue. The result shows that despite the phenomenon, the husbands still play their role as breadwinners, namely the secondary one. This stems from how they understand the rule of each family party, implying how religious teachings interplay with modern realities.

Authors: PANDEY RITESH 
Published: January 2025

Abstract

The rising popularity of cryptocurrencies has led to increased interest in predicting their prices, particularly in the case of Bitcoin due to its volatility and complexity. While past research has used machine learning to improve Bitcoin price prediction accuracy, there has been limited focus on exploring diverse modeling techniques for datasets with varying structures and dimensions. This study aims to forecast Bitcoin prices using machine learning techniques by categorizing them into daily prices and high-frequency prices. The project specifically employs the Random Forest Classifier algorithm to predict Bitcoin prices using historical data from July 2010 to May 2023. The dataset undergoes preprocessing and feature engineering to extract relevant features for the model. The trained algorithm is then optimized through hyperparameter tuning. Additionally, a simulation dashboard is created using Flask, a popular web framework, to allow users to evaluate different machine learning algorithms for predicting Bitcoin prices. The results of the project demonstrate that the Random Forest Classifier algorithm achieved 99% accuracy in predicting Bitcoin prices, highlighting the effectiveness of machine learning techniques in this context.
