Published: February 2024

This study explored the complex relationship between magnetic fields and light polarization in thin films of ferrofluid. Utilizing techniques such as polarized light imaging, multipolar expansion, and Mueller matrix formalism, this work investigated the formation of isogyres, which are distinct patterns observed when polarized light passes through the ferrofluid under various magnetic field configurations. The analysis revealed that the alignment of nanoparticles in response to the magnetic field resulted in the formation of a diffraction grating, influencing light polarization. Through the application of Stokes vectors and Mueller matrices, we gained insights into the complex interplay between magnetic fields and optical properties. The experiment presents the evolution of isogyres from straight lines to parabolas under the influence of a hexapolar magnetic field. The Mueller matrix effectively represented the magnetic field's impact on polarized light, highlighting dark regions corresponding to isogyres. We also report the formation of some patterns related to atmospheric optics and their analogy with the formation of patterns of the parlaseric circle and the luminous horocycle.

Modeling, analyzing and simulating the dynamics of Tuberculosis-Covid-19 co-infection
Authors: Alemneh Haileyesus Tessema , Melese Zinabu Teka 
Published: February 2024

Covid-19 and tuberculosis (TB) are two significant infectious illnesses that may pose significant threats to the public health and their co-infection aggravates the issue. Through the use of a set of nonlinear ordinary differential equations and contaminated surfaces from SARS-CoV-2 in the environment, we developed and investigated a mathematical model in this study for the dynamics of the co-infection of Covid-19 and TB transmission. The free equilibrium point of the disease was determined and its stability was investigated. The next generation matrix approach is used to determine the model’s basic reproduction number. The disease-free equilibrium point is not globally asymptotically stable, but it is locally asymptotically stable if R0 < L We found key model parameters for disease dynamics spread using normalized forward sensitivity analysis. From the numerical simulation results, we conclude that government stakeholders should work in reducing the transmission mechanisms of both diseases. In addition, they should look on mechanisms for removing SARS-CoV-2 contaminated surfaces from the community.

Evaluation of Cardiovascular Autonomic Dysfunction According to Heart Rate Turbulence and Variability in Patients with Benign Paroxysmal Positional Vertigo
Authors: Dural İbrahim Etem , Kuzu Selçuk , Günebakan Çağlar , Yıldız Erkan 
Published: February 2024

Introduction: The relationship between benign paroxysmal positional vertigo (BPPV) and cardiovascular autonomic dysfunction is not clear. Disruption of the balance between the sympathetic and parasympathetic systems causes various diseases. It is believed that disorders of the parasympathetic system, particularly, may be responsible for causing BPPV. Heart rate variability (HRV) and HRT (heart rate turbulence), which show autonomic dysfunction, are two non-invasive tests that show the relationship of the heart rate with the autonomic nervous system. The purpose of the present study was to evaluate the relationship between autonomic dysfunction and BPPV in patients with BPPV by using HRV and HRT, which are non-invasive laboratory parameters.
Patients and Methods: A total of 100 age- and gender-matched volunteers and 100 patients with BPPV were selected for the study between January 2015 and January 2020. We obtained HRT and HRV parameters from 24-hour ECG Holter recordings. We considered a TO above 0 and a TS above 2.5 to be abnormal. We compared the parameters between groups.
Results: A significant difference was observed between the BPPV and control groups in the HRV parameters SDNNI (p= 0.036), SDANN (p= 0.045), and HRT parameter TS (p= 0.048). We showed that abnormal TO (p= 0.025) and TS (p= 0.038) values were significantly higher in the patient group.
Conclusion: Parasympathetic autonomic dysfunction was demonstrated by the lower HRV and HRT values observed in the patients with BPPV compared to the control group in the present study. The present findings must be confirmed with a much larger number of patients and multi-center studies.

Published: February 2024

Introduction: Traditionally, atrial fibrillation is considered a comorbid factor for coronary artery bypass surgery as well as other surgeries, however, current literature is still limited. In this study, the effects of preoperative atrial fibrillation on coronary artery bypass grafting were investigated.
Patients and Methods: Following the hospital’s clinical trials ethics committee approval, data from 151 patients who underwent isolated coronary artery bypass surgery were collected with the assistance of the hospital’s electronic records system. The follow-up duration was 12 months. Statistically significant P value cut-off taken as 0.05.
Results: The mean age was 61.5 and 26.6% (n= 40) of the patients were female. Preoperative atrial fibrillation (Afib) prevalence was 13.3% (n= 20). No significant differences were observed in patient demographics, metabolic, systemic, and cardiovascular conditions between the group with preoperative atrial fibrillation and the control group (p> 0.05). However, the previous myocardial infarction rate was found higher (38.9 vs. 70.0, p= 0.009), and carotid artery stenosis disease prevalence was found lower (18.2 vs. 0.0, p= 0.038), also mean glomerular filtration rate (GFR) was found lower (85.9 vs. 69.7, p= 0.002) in the patients with Afib. Intraoperative parameters were not statistically different among the group (p> 0.05). Despite the preoperative dysthymia history, myocardial infarction prevalence, and poor kidney function; there was no difference in terms of postoperative acute kidney injury rates, stroke rates, perioperative complication rates, and thirty-day and 12-month survival (p> 0.05). However, the re-revascularization requirement was higher in patients in the Afib group.
Conclusion: Atrial fibrillation is a prevalent comorbidity in coronary artery bypass grafting patients. However, it was not found as a factor that related to mortality or morbidity and coronary surgery seems feasible in this patient group.

Published: February 2024

Introduction: Surgical treatment of structural heart diseases continues to predominantly involve median sternotomy, despite the ongoing trends favoring minimally invasive approaches that have persisted for many years. In this study, we present data on structural heart disease (SHD) surgeries conducted by our institute using a right mini-thoracotomy approach.
Patients and Methods: This single-center retrospective study included 58 patients who underwent right minithoracotomy procedures between February 2018 and June 1, 2023. Preoperative demographic and medical data were collected from patient files and records. Perioperative and 30-day outcome data were obtained through the national electronic record system.
Results: The average age of the participants was 39.9. Female patients accounted for 31.6% (n= 18) of the participants. The majority of surgeries in this study involved peripheral cannulation and conventional cardioplegia. Mitral valve repair and atrial septal defect closure were the most common procedures performed. Intraoperative outcomes showed favorable results, with no instances of significant bleeding, structural complications, or mortality. Regarding the postoperative 30-day outcomes, the stroke rate was 1.8% (n= 1) among the patients. There were no reported cases of transient ischemic attack (TIA), myocardial infarction (MI), and mortality. The conversion to median sternotomy occurred in 3.4% (n= 2) of the cases. Reoperation and reexploration were required in 1.8% (n= 1) of the cases. The mean length of stay in the ICU was 1.7 days, while the mean length of ward stay was 4.2 days.
Conclusion: This study contributes to the evidence supporting the shift towards minimally invasive approaches in the surgical management of structural heart disease. The low rate of intraoperative conversion, absence of major complications, and favorable postoperative outcomes highlight the safety and feasibility of right mini-thoracotomy. Continued advancements in surgical techniques and clinical expertise are expected to further optimize patient outcomes and improve the quality of care in this field.

Introduction: The pulmonary embolism severity index (PESI) score is used to determine the risk of mortality and severity of complications in acute pulmonary embolism (APE). Tricuspid annular plane systolic excursion/systolic pulmonary arterial pressure (TAPSE/sPAP) ratio has been recently shown to predict poor 30-day clinical outcome in APE. We aimed to analyze the prognostic value of the TAPSE/sPAP ratio for prediction of 30-day adverse clinical outcomes in APE patients, similar to PESI score.
Patients and Methods: This study enrolled 203 retrospectively evaluated patients (female 108, mean age= 57.4 ± 15.5 years) with the diagnosis of APE between 2010 and 2020. All patients underwent transthoracic echocardiography before specific APE treatment. Primary endpoints were 30-day mortality, thrombolytic therapy requirement, mechanical ventilation requirement, mental status deterioration, and persistent hypotension (systolic blood pressure <90 mmHg). The study population was divided into two groups according to the TAPSE/sPAP ratio= 114 patients in group 1 with a low TAPSE/sPAP ratio (<0.494) and 89 patients in group 2 with a high TAPSE/sPAP ratio (>0.494).
Results: The incidence of in-hospital mortality (4.4 vs. 0%, p= 0.045], 30-day mortality [n= 8 (7.0%); 0 (0%), p= 0.009] and primary adverse outcomes (35.1 vs. 0%, p< 0.001) were higher in group 1. The TAPSE/sPAP ratio was negatively correlated with PESI (r= -0.716, p< 0.001). In multivariate logistic regression analyses revealed that the TAPSE/sPAP ratio [OR= 0.001, 95C% CI= 0.000-0.476, p= 0.028] was an independent predictor of 30-day mortality in APE.
Conclusion: The present study showed that the TAPSE/sPAP ratio may be used in clinical practice for the prediction of short-term adverse outcome risk estimation in APE patients, similar to PESI score.
Atrial Dispersion Predicts Atrial Fibrillation in Mitral Stenosis: A Five-Year Follow-Up SpeckleTracking Echocardiography Study
Authors: Candan Özkan 
Published: February 2024

Introduction: Atrial dispersion showing increased electrical heterogeneity may be associated with the occurence of atrial fibrillation (AF). In our study, it was aimed to investigate the effects of atrial dispersion evaluated by speckle tracking echocardiography on the occurence of AF on in patients with mild to moderate rheumatic mitral stenosis.
Patients and Methods: Sixty-two patients with rheumatic mitral stenosis with sinus rhythm, asymptomatic or NYHA 1 symptoms were included in the study. The time to peak atrial strain was measured for each segment by speckle tracking echocardiography in two and four-chamber views. Atrial dispersion was calculated by taking the standard deviation of time to peak strain in 12 left atrial segments. Echocardiographic and clinical parameters of the patients were compared according to the development of AF.
Results: During follow-up (mean follow-up duration, 49.9 ± 12.9 months), 19 patients (30%) developed AF. Compared to patients who did not develop AF at follow-up, patients with AF were older (46.8 ± 10.2 vs. 35.9 ± 12, p= 0.001), while mitral valve area (MVA) (1.38 ± 0.1 vs. ± 1.49 ± 0.18 vs. p= 0.02), PALS (13.7 ± 4 vs. 18.8 ± 5.5, p= 0.001) and PACS (6 ± 2.3 vs. 8.2 ± 3.8, p= 0.002) were found to be lower. Atrial dispersion was found to be increased in patients who developed AF (63.2 ± 13.5 vs. 46.1 ± 22.3, p= 0.003). Age, atrial dispersion and PALS were determined as independent predictors of AF development in Cox regression analysis.
Conclusion: Atrial dispersion, a new parameter measured by STE, predicts the development of AF. Increased atrial dispersion may provide additional benefits in initiating prophylactic antiarrhythmic drug therapy or anticoagulants.

Published: February 2024

Abstract. This study provides the first inter-comparison of different state-of-the-art approaches and frameworks that share a commonality in their utilization of satellite remote-sensing data to quantify irrigation at a regional scale. The compared approaches vary in their reliance on either soil moisture or evapotranspiration data or their joint utilization of both. The two compared frameworks either extract irrigation information from residuals between satellite observations and rainfed hydrological models in a baseline framework or use soil water balance modeling in a soil-moisture-based inversion framework. The inter-comparison is conducted over the lower Ebro catchment in Spain where observed irrigation amounts are available for benchmarking. Our results showed that within the baseline framework, the joint approach using both soil moisture and evapotranspiration (ET) remote-sensing data only differed by +37 mm from the irrigation benchmark (922 mm) during the main irrigation season over 2 years and by +47 and −208 mm for approaches relying solely on soil moisture and ET, respectively. A comparison of the different frameworks showed that the main advantage of the more complex baseline framework was the consistency between soil moisture and ET components within the hydrological model, which made it unlikely that either one ended up representing all irrigation water use. However, the simplicity of the soil-moisture-based inversion framework, coupled with its direct conversion of soil moisture changes into actual water volumes, effectively addresses the key challenges inherent in the baseline framework, which are associated with uncertainties related to an unknown remote-sensing observation depth and the static depth of the soil layers in a conceptual model. The performance of the baseline framework came closest to the irrigation benchmark and was able to account for the precipitation input, which resulted in more plausible temporal distributions of irrigation than what was expected from the benchmark observations.
