Summary of Creative Psychology of Creativity in Pillaitamil Literature
Authors: S Vignesh 
Published: January 2023

Pillaitamil is one of the 96 genres of Tamil literature. Pillaikavi literature doesn’t originate in foreign language. Pillaitamil literature praises the Lord or the great human being as a child in the seasons such as Pavatu, Sengirai, Sappani, Muttham, Alakham, Ambuli, Chittil, Siruparai, Siruthaer, Ammanai, Osal, Neeradal etc. The purpose of this article is to approach such genre of Pillaitamil literature from a psychological point of view. Literature is a creation of the mind. Thus, the psychological elements found in literature are categorized as creator, creative method, storyteller and reader. In these ways, creative psychology is revealed in Pillaitamil literature. It is highlighted that the mood of the creator who sings Pillaitamil is in three stages namely motherhood, childhood and as a young girl. This article explains the mood of the mother in the seasons like the period of Kaapu, Ambuli and Thala, the psychology of the girl in the season of childhood, the movement behaviours of children in other seasons, the seasons like sengir are the impulses that the mother causes to her children.

Authors: Mourad Faisal , Fikry Mohamed , Gamal Mohamed 
Published: January 2023

Background: Femoral cannulation is commonly used during minimally invasive cardiac surgery. We evaluated the occurrence of postoperative groin complications after femoral cannulation in minimally invasive cardiac surgery.
Methods: This retrospective study included 140 patients who had minimally invasive surgery with femoral cannulation. One hundred twelve patients (80%) had mitral valve surgery, 24 patients (17.1%) had atrial septal defect repair, and four patients (2.9%) had myxoma excision. Their mean age was 41.47± 11.71 years, and 60% were females (n= 84).
Results: Groin complications occurred in 14 patients (10%); seroma developed in 11 patients (7.9%), two had femoral artery hematoma (1.4%), and 1 (0.7%) patient had femoral arterial dissection, which was primarily repaired. There were no differences in the preoperative data between patients with and without groin complications. Patients with groin complications had non-significantly longer cardiopulmonary bypass time (155± 43.6 vs. 129.8± 35.7 min, P= 0.2) and longer hospital stay (13±3.8 vs. 11.6±4.3 days, P= 0.2)
Conclusions: Groin complications are relatively uncommon in minimally invasive procedures and are usually simple to manage.

Published: January 2023

Background: Even though tricuspid regurgitation (TR) is a frequent cardiac valve disorder, and tricuspid valve annuloplasty (TVA) has been evolved to manage TR for more than 50 years, there is still a substantial controversy regarding the best durable method for TVA. We reported our midterm (3 years) outcomes of TVA using autologous pericardial (AP) band comparing it with DeVega annuloplasty for the management of functional TR.
Methods: Between January 2017 and November 2018, about 175 cases with moderate or more TR underwent TVA as a part of primary left-sided valve replacement surgery. Autologous pericardial (AP) TVA was performed in 100 patients, and DeVega TVA in 75 patients.
Results: Both groups are comparable as regards preoperative characteristics. Immediate postoperatively, regarding NYHA class, degree of TR, ejection fraction, and pulmonary artery systolic pressure, there was a marked improvement within the 2 groups compared to the preoperative values, without a significant difference between both groups. 94% of patients completed the follow-up period. In hospital death was 2% in the AP group, and 1% in the DeVega group. The AP group showed a marked improvement in the mean degree of TR at the same follow-up period compared to the DeVega group, 12% patients of the AP group and 21% patients of the De Vega group had 3+ or 4+ TR at 3 years postoperative follow up. There was a marked improvement in the Diastolic tricuspid annuloplasty diameter in the AP group compared to the DeVega group. There were 6.3% late deaths in our study.
Conclusion: TVA with an AP was more durable than the DeVega in avoiding postoperative TR progression on the midterm results.

Authors: Amr Mohamed , Fayad Elsayed , Kamal Yasser 
Published: January 2023

Background: Redo mitral valve replacement (redo-MVR) remains a challenge despite advances in surgical techniques. Little is known about the outcomes of redo-MVR in patients with rheumatic heart disease. We aimed To evaluate the in-hospital outcomes and associated risk factors for mortality and morbidity after re-operative mitral valve replacement in patients with initial rheumatic heart disease.
Methods: This retrospective cohort study included 214 patients, 96 males (44.9%) and 118 females (55.1%), who underwent redo-MVR between January 2015 and December 2020. The mean age was 41.87±11.7 years. European Heart Surgery Risk Assessment System II (EuroSCORE II), Age, Creatinine, Ejection Fraction (ACEF) scores were used for risk stratification. The primary endpoints were in-hospital mortality, major morbidity (renal failure, prolonged ventilation, stroke, reoperation, or deep sternal wound infection), and the composite outcome of mortality and/or morbidity).
Results: Major morbidities occurred in 31.8% of patients, and the in-hospital mortality rate was 19.6%. Predictors of mortality were New York Heart Association class (NYHA) III/IV (OR: 5.4; p˂ 0.001), cardiogenic shock (OR: 13.74, p˂0.001), low left ventricular ejection fraction (LVEF) (OR: 4.36; p= 0.01), and perioperative intra-aortic balloon pump (OR: 6.79; p= 0.01). The significant predictors of mortality and/or major morbidity were NYHA III/IV (OR: 2.39; p˂0.001), low LVEF (OR: 4.44; p= 0.001), active endocarditis (OR: 2.4; p=0.04), and perioperative IABP (OR: 3.88; p= 0.045). EuroSCORE II had better accuracy than the ACEF score to predict adverse outcomes (AUC: 0.70 [95% CI: 0.63-0.78] versus 0.58 [95% CI: 0.50-0.66], p= 0.01) .
Conclusion: Advanced NYHA class and low LVEF could be associated with poor outcomes after redo-MVR in patients with primary surgery for rheumatic mitral valve disease. EuroSCORE II is a helpful tool for risk stratification during redo-MVR.

Authors: Fouly Mohamed , Khairy Tarek 
Published: January 2023

Background: The CarboMedics Top-Hat aortic valve prosthesis was designed to be implanted in a supra-annular position. This study aimed to compare the hemodynamic performance of the Top-Hat aortic prostheses versus the standard CarboMedics aortic valve prostheses.
Methods: The study included 98 patients who had aortic valve replacement and were divided into two groups. Group A included 60 patients who had standard aortic valve prostheses, and Group B included 38 patients who had the Top-Hat aortic prostheses. The study endpoints were hospital outcomes, the effective orifice area, and the pressure gradient during a one-year follow-up.
Results: There was no significant difference in the baseline echocardiographic data and risk factors between the groups. The patients who had Top-Hat aortic prosthesis were younger, with a mean age of 47.5 (44-55) years, and those who had the standard prosthesis were 53.5 (48-56) years old (P= 0.02). The cardiopulmonary bypass time was significantly less in the Top-Hat prosthesis group with an average of 78 min (75- 81) compared to 88 min (84- 95) in the other group (P ˂0.001). The effective orifice surface area was significantly larger in the group with Top-Hat prosthesis; 0.9 mm/m2 (0.88- 0.92) compared to 0.84 mm/m 2 (0.79- 0.87) for the standard aortic valve prosthesis group (P ˂0.001). The pressure gradient over the aortic valve decreased significantly postoperatively (coefficient -1.98 (-2.21- -1.75); P˂0.001). Patients with Top-Hat valves had significantly lower gradient (coefficient: -4.22 (-6.61- -1.82); P= 0.001), while age had no effect on the pressure gradient (coefficient: 0.1 ( -0.07- 0.27); P= 0.25).
Conclusion: The Top-Hat CarboMedics prostheses could be superior to the standard CarboMedics aortic valve prosthesis regarding the effective orifice area and pressure gradient over the valve.

Authors: Labib Dokhan Ahmed , Moheb Ibrahim Islam , Mohammed Abdel Sadek Sarah , Gamal El-din Hagag Mohammed 
Published: January 2023

Background: The role of video-assisted thoracoscopic surgery (VATS) for managing organized empyema is still limited. This study compared VATS versus open decortication in patients with chronic pleural empyema.
Methods: This randomized controlled trial included 58 patients with stage III empyema. Patients were divided into two groups. Group A (n= 30) included patients who had decortication through an open thoracotomy, and Group B (n= 28) included VATS decortication patients. Two patients in the VATS group were converted to the open approach and were excluded from the analysis.
Results: The mean age in Group A was 48.23 ± 8.44 years and 49.79 ± 7.85 years Group B (p= 0.47). There were 16 males (53.3%) in Group A and 15 (63.6%) in Group B (p= 0.99). The operative time was 336.0 ± 67.60 min in Group A and 291.07 ± 56.66 min in Group B (p= 0.01). There was no difference in intraoperative complications between groups. Postoperative hospital stay (p= 0.23) and ICU admission (p= 0.24) did not differ between groups. In Group A, the pain scale was 8 (6- 8), and it was 4 (2- 4) in Group B (p˂ 0.001). No difference was recorded in the postoperative complications between groups.
Conclusion: The outcomes of VATS in managing stage III empyema are comparable to the open approach. VATS has the advantage of lower postoperative pain. VATS could be an alternative to open decortication in patients with stage III pleural empyema.
Impact of Levosimendan on High Sensitivity Cardiac Troponin-T after Valvular Heart Surgery: A Randomized Clinical Trial
Authors: Habib Mahmoud , Torky Mohammad , Abdelwahab Amr , Wahby Ehab 
Published: January 2023

Background: Various measures have been used for maintaining adequate cardiac output after valvular heart surgery. The study aimed to evaluate the impact of levosimendan on high-sensitivity cardiac troponin-T after valvular heart surgery.
Methods: This prospective randomized clinical trial included 400 patients. All patients above 18 years who underwent elective cardiac valvular surgery were randomly classified into two equal groups. Group A (n= 200) included patients who received levosimendan during weaning from cardiopulmonary bypass, and Group B (n= 200) included patients who did not receive levosimendan.
Results: Cardiopulmonary bypass, cross-clamp, reperfusion times, and use of inotropes were insignificant between groups. Troponin levels on days 0, 1, and 2 showed a significant decrease in Group A (P˂0.001). Postoperative ejection fraction was significantly higher in Group A (66.10 ± 4.41 vs. 46.60 ± 3.98; P˂0.001). Duration of mechanical ventilation (4.70± 1.16 vs. 10.70± 0.82; P˂ 0.001), intensive care (1.90 ± 0.57 vs. 5.90 ± 1.29; P˂0.001), and hospital stay (6.90 ± 1.91 vs. 13.40 ± 3.10; P˂0.001) were significantly lower in Group A.
Conclusions: Levosimendan could have cardioprotective effects, resulting in a significant reduction of postoperative high sensitivity cardiac troponin-T release after valvular heart surgery. It could be associated with improved left ventricular ejection fraction, short duration of mechanical ventilation, ICU, and hospital stay.
Impact of the degree of tricuspid valve tethering on the early outcome of tricuspid valve repair with the De-Vega technique
Authors: Albatrek Hani , Ramadan Ahmed 
Published: January 2023

Background: Functional tricuspid regurgitation (TR) is usually caused by leaflet tethering, and annuloplasty is usually recommended to repair annulus dilatation. This work aimed to evaluate the impact of the degree of the tricuspid valve (TV) tethering on the early outcome of tricuspid valve repair with the De-Vega technique.
Methods: This prospective study included 50 patients with De-Vega tricuspid valve repair. Patients were divided into two groups; Group A (n= 25) included patients with tricuspid valve tethering of 8 mm or less, and Group B (n= 25) included patients with tricuspid valve tethering distance of more than 8 mm.
Results: The mean age of Group A was 46.1 ±3.5 years compared to 49.6 ±7 years in Group B. There were significant differences in postoperative ejection fraction (48.7 ±12.5 vs. 39.1 ±9.4 %, P= 0.003), TV tethering distance (0.6 ±0.2 vs. 1.1 ±0.4 cm, P <0.001), and area (1.1 ±0.5 vs. 2.6 ±0.9 cm2; P<0.001), and right ventricle fractional area (32.2± 7.9 vs. 25.4 ±9.7 cm2, P= 0.008) in Group A vs. B, respectively. There were no differences in postoperative complications, ICU, and hospital stay between groups.
Conclusion: Residual tricuspid regurgitation after De-Vega annuloplasty could be related to TV tethering distance. Increased TV tethering distance could be associated with reduced postoperative ejection fraction.

Published: January 2023

Background: Gastrointestinal tract (GIT) complications are associated with increased morbidity and mortality after cardiac surgery. Therefore, The goal of this research was to estimate the frequency of GIT and hepatic complications after cardiac surgery and to determine the risk factors for these complications. Additionally, we studied the effect of these complications on the outcomes of surgery.
Methods: This longitudinal study included 139 consecutive patients who underwent elective cardiac surgery. Patients were grouped according to the GIT and hepatic complications into two groups. Postoperative outcomes were compared between the two groups.
Results The mean age was 59.43 years, and 106 patients were males (76%). The GIT and hepatic complications rate was 15.8% (n= 22). Hepatic dysfunction occurred in 8.6% of cases, GIT bleeding in 2.9%, paralytic ileus in 2.2%, fulminant hepatic failure in 2.2%, and GIT bleeding combined with paralytic ileus in 0.7%. The overall mortality was 7.2 % (n= 10). The mortality rate in patients who developed GIT and hepatic complications was 45.5% (n= 10 out of 22 patients). There was statistically significantly higher mortality (10 (45.5%) vs. 0; P= 0.001), cardiac arrest (10 (45.5%) vs. 3 (2.6%); P= 0.001), and reoperation rate (5 (22.7%) vs. 6 (5.1%); P= 0.005) among patients with GIT or hepatic complications.
Conclusion: Patients with hepatic and GIT complications could have higher mortality, morbidity, and longer hospital stay than the non-complicated group.

Sequential Track Fusion in UKF-based Multi-Sensor Networks: A Case of Slip Estimation in Wheeled Mobile Robots
Authors: Zarei Mahboubeh , Chhabra Robin , Mottaghi Mohammadreza 
Published: January 2023

<p>Accurate wheel slip estimation facilitates Wheeled Mobile Robots (WMRs) with improved localization and traversability monitoring which are crucial to their autonomy in challenging environments. Although distributed track-level fusion offers better computational efficiency, often sensor-level fusion is adopted in slip estimators. Extending upon our earlier work, we develop a novel explicit track-to-track fusion algorithm for UKF-based multi-sensor networks that has immediate application to slip ratio estimation in WMRs. The algorithm demonstrates better consistency compared to the existing fusion techniques, since it implements an optimal fusion rule to sequentially combine local tracks. It also saves computational power due to the recursive propagation of cross-covariance matrices based on the statistical linearization technique, instead of performing online optimizations. We prove that this recursion only requires the information of the first and last tracks in a sequence if all local tracks are unbiased. We rigorously study various key properties of the developed fusion algorithm and show its superior level of confidence when compared to the two prominent fusion methods of sequential and batch covariance intersection. The slip ratio estimation in a six-wheel WMR is considered as a case study, where the steerable wheel sets act as a network of sensors. The proposed slip estimator works based on the rigid body kinematics and readings of purely proprioceptive sensors, i.e., an inertial measurement unit and encoders. The slip estimator's performance is evaluated in a high-fidelity software-in-the-loop simulation environment connecting MATLAB and CM Lab's Vortex Studio software. In a comparison study that considers four rival strategies, we show the superiority of the proposed fusion method offering a balance between consistency, accuracy, and speed in real-time slip estimations.</p>

UTransBPNet: A General Deep Learning Model for Cuffless Blood Pressure Estimation under Activities
Authors: Zheng Yali , Liu Qing , Hong Jingyuan , Wu Shenghao , Zhang Yuanting , zheng Yali 
Published: January 2023

<p>The main challenge in cuffless blood pressure (BP) monitoring lies in its inaccuracy during daily activities. Many previous works either lacked appropriate validation with sufficient intra-individual BP variations, or showed unsatisfactory estimation accuracy under activities. This study introduces a novel deep learning model called <em>UTransBPNet</em>, which aims to improve the estimation accuracy and tracking capability of intra-individual BP changes under activities. <em>UTransBPNet</em> combines the Unet architecture with self- and cross-attention from transformer to estimate BP waveforms, which are then further regressed to systolic (SBP) and diastolic BP (DBP) using additional fully connected layers. The model’s performance was thoroughly evaluated in three distinct datasets: one public dataset (Dataset_MIMIC) and two datasets during activities (Dataset_Drink and Dataset_Exercise). Under subject-independent validation, the model achieved mean absolute differences (MADs) of 4.38 mmHg for SBP and 2.25 mmHg for DBP in Dataset_MIMIC. Additionally, the tracking capability of intra-individual BP variations during activities were also significantly improved. In Dataset_Drink, Pearson's correlation coefficients for SBP and DBP were 0.61±0.17 and 0.62±0.13, respectively. In Dataset_Exercise, the corresponding correlation coefficients were 0.82±0.11 for SBP and 0.72±0.18 for DBP. Furthermore, this study for the first time tested the generalization capability across different activities. The results showed that our model, with small-sized scenario-specific data for finetuning, exhibited a good cross-scenario generalization capability. However, it degraded significantly when there were differences in the BP distributions and variation patterns between the datasets. In conclusion, <em>UTransBPNet</em> shows promise as a deep learning model for accurate cuffless BP estimation and tracking BP changes during activities. </p>

Published: January 2023

Objective: Vascular complications in type 2 diabetes mellitus are an important cause of morbidity and mortality. Also, endothelial dysfunction arises with vascular ageing during the postmenopausal period. Our objective in this study was to evaluate inflammation and endothelial function parameters and their possible diagnostic roles in type 2 diabetic postmenopausal patients.
Material and Methods: The study was conducted on four groups, including type 2 diabetic premenopausal (n:20), non-diabetic premenopausal (n:20), type 2 diabetic postmenopausal (n:20), and non-diabetic postmenopausal subjects (n:20). Serum endothelin-1 (ET-1), endothelial nitric oxide synthetase (eNOS), interleukin-6 (IL-6), tumor necrosis factor α (TNF-α), and chitinase-3-like protein 1 (YKL-40) levels were determined as inflammatory and endothelial function markers using ELISA kits.
Results: Serum ET-1, IL-6, and YKL-40 levels were higher in the type 2 diabetic postmenopausal group compared to the non-diabetic premenopausal group (p<0.01, p<0.05, and p<0.01, respectively). ET-1, IL-6, and YKL-40 levels were higher in the type 2 diabetic postmenopausal group compared to the non-diabetic postmenopausal group (p<0.001, p<0.05, and p<0.01 respectively). ROC analysis revealed serum ET-1 (AUC 0.933, sensitivity 87.5%, specificity 85.7%), IL-6 (AUC 0.812, sensitivity 56.3%, specificity 92.8%), and YKL-40 (AUC 0.880, sensitivity 81.2%, specificity 92.8%), as good diagnostic parameters, especially in the type 2 diabetic premenopausal vs. non-diabetic premenopausal cohorts.
Conclusion: Serum ET-1, IL-6, and YKL-40 levels were at the highest levels in the 2 diabetic postmenopausal group, and the increase in these markers was remarkable in diabetes compared with menopausal periods. Also, ET-1, IL-6, and YKL-40 were good diagnostic parameters for detecting endothelial function and inflammation in type 2 diabetic postmenopausal and non-diabetic premenopausal cohorts.
