Published: December 2024

Objectives: The primary aim of this study was to investigate the potential relationship between non-alcoholic fatty liver disease (NAFLD) and contrast-induced nephropathy (CIN) in patients with non-ST-elevation myocardial infarction (NSTEMI). As a secondary goal, we aimed to explore the impact of NAFLD on short-term adverse events and coronary artery disease (CAD) severity in patients with NSTEMI.
Methods: Three hundred and seven NSTEMI patients were included in this study. Laboratory analyses of these patients were performed before the procedure and 48–72 h after the procedure, and all patients underwent pre-procedure 2-dimensional transthoracic echocardiography and pre-discharge abdominal ultrasonography. The NAFLD (-) and (+) groups were compared statistically in terms of CIN, major cardiovascular-cerebrovascular adverse events (MACCE), and coronary artery severity (assessed by syntax score).
Results: The mean age of the 307 consecutive patients included in the study was 61.58±12.39 (min-max: 26–94). The rates of CIN (primary objective) and MACCE and syntax scores (secondary objective) were comparable in both groups.
Conclusion: In patients with NSTEMI, there was no relationship between NAFLD and CIN and short-term MACCE. Furthermore, NAFLD may not have an impact on the CAD severity in such patients. Based on these results, NAFLD is not a risk factor for CIN, short-term mortality, or CAD severity in NSTEMI patients.

Published: December 2024

Objectives: Aortic coarctation is defined as the narrowing of the aortic lumen secondary to hypertrophy of the posterolateral aortic wall’s media layer. The coarctation is locates between the junction from ductus arteriosus to the left subclavian artery and left hemi aortic arch. Aortic coarctation provokes many severe and lethal complications, such as severe aortic stenosis, aortic aneurysms, pseudoaneurysms, stroke, and premature coronary artery disease, unless it had not been repaired in the meantime the initiation of the symptoms.
Methods: We presented the consecutive nine patients who underwent aortic coarctation open surgical repair between 2015 and 2020 which initiated ascending-to-descending aortic bypass and then concomitant operations for the secondary cardiac pathology such as ascending aortic aneurysm, Type A aortic dissection and sinus valsalva aneurysm required in some cases. Patients were a median age of 26 years old (range, 19–41 years). About 11% of the patients (n=1) presented to our emergency room with severe chest pain and acute Type 2 aortic dissection was diagnosed by the surgical team, and he underwent operation immediately. The supracoronary aortic replacement and ascending to descending aortic bypass procedures were performed sequentially. About 44% of the patients (n=4) were diagnosed as isolated aortic coarctation and only ascending –to- descending aortic bypass was performed electively. About 22% of the patients (n=2) had ascending aortic aneurysm without aortic valve pathology. These patients underwent supracoronary aortic replacement as concomitant procedure to ascending to descending aortic bypass. About 22% of the patients (n=2) had bicuspid aortic valve and sinus Valsalva aneurysm; therefore, the Bentall procedure was implemented concomitantly.
Results: There were not any early deaths reported. Any neurologic complications including neither paraplegia nor stroke revealed during post-operative follow-up. About 88% of patients (n=8) were discharged with stable hemodynamic parameters in 2 weeks. About 11% of these patients (n=1) who underwent Bentall procedure concomitantly had third-degree atrioventricular block as a serious rhythm problem then a permanent pacemaker implanted. This patient had been discharged with stable hemodynamic parameters and pacemaker settings were controlled by the cardiology department.
Conclusion: The extra anatomical ascending-to-descending aortic bypass is a safe and feasible method for the open surgical coarctation repair, and it provides concomitant procedures for other cardiac pathologies, which require open surgical treatment.

Authors: Voronena Natalya , Troshina Galina 
Published: December 2024

This study investigates the Hall effect in n- and p-doped germanium samples through experimental measurements of Hall voltage, electrical conductivity, charge carrier mobility, and carrier concentration under varying magnetic fields and temperatures. The experimental setup involved measuring Hall voltage as a function of control current, magnetic field induction, and temperature using a TSE Co, LTD company Hall-effect unit. The linear dependence of the Hall voltage on the magnetic field was confirmed, yielding regression line slopes of b = 0.144 VT−1 ± 0.004 VT−1 for n-germanium and b = 0.125VT−1 ± 0.003VT−1 for p-germanium. Corresponding Hall constants were calculated as RH = 4.8×10 m-3 /C and RH = 4.17×10 m-3 /C. Electrical conductivities were determined as σ = 53.6 S/m for n-germanium and σ = 57.14 S/m for p-germanium. The Hall mobilities were found to be μH = 0.257±0.005 m2 /Vs for n-germanium and μH = 0.238±0.005 m2/Vs for p-germanium. Carrier concentrations were n = 13.0×1020 m−3 for electrons and n =14.9×1020 m−3 for holes. From temperature-dependent measurements, the energy bandgaps were calculated as Eg = 0.50 ± 0.04 eV for n-germanium and Eg = 0.72 ± 0.03 eV for p-germanium. The experimental findings provide comprehensive insights into the electronic properties of doped germanium, highlighting its behavior under magnetic fields and varying temperatures, with precise parameter evaluation crucial for semiconductor applications.

Authors: Moorthy Swathy , Bhaskar Emmanuel , Singh Shivakumar , Silambanan Santhi 
Published: December 2024

BACKGROUND
Tuberculosis (TB) is a common infection causing huge morbidity and mortality to mankind. The analytical methods used in diagnosing TB are not sensitive in paucibacillary infections and also require trained technical personnel. MicroRNAs are stable in serum and other body fluids, and hold great potential in the diagnosis of TB.
AIM
To analyze the dysregulated microRNA profiles among patients with cavitatory and non-cavitatory pulmonary TB.
METHODS
The prospective study will be conducted in a tertiary care center in India. Adult patients with newly diagnosed pulmonary TB will be included. There will be two groups: Patients with sputum positive pulmonary TB with cavity and without cavity (group1), and apparently healthy individuals (group 2). The participants will undergo sputum examination, Xpert Mycobacterium TB complex/resistance to rifampin (Mtb /RIF) assay, chest X-ray, and blood investigations and serum microRNA detection. Ethics approval has been obtained. Written informed consent will be obtained. Appropriate statistical analyses will be used.
RESULTS
MicroRNAs will be correlated with sputum positivity, Xpert Mtb /RIF assay, radiological involvement, inflammatory markers, and course of the disease among cases and controls.
CONCLUSION
MicroRNAs could serve as potential diagnostic biomarkers in diagnostically challenging TB patients.

Introduction: Hyponatremia is one of the most common hydroelectrolytic disorders in patients with neurocritical pathology. Estimating blood volume in critically ill patients with hyponatremia is a challenge, and this is where point-of-care ultrasound (POCUS) becomes relevant.Methods: An observational, analytical, prospective, and longitudinal study was conducted in an ICU with a high influx of neurocritical patients. Thirty-one neurocritical patients who developed acute hyponatremia participated. They were evaluated clinically, analytically, and underwent ultrasound measurements at the bedside of the patients. It was determined which of the variables (clinical, analytical, and ultrasound) achieved the greatest sensitivity and specificity when determining blood volume. Results: More than half developed hyponatremia during their stay in the ICU, the predominant gender was male with more than 61% and more than 77% had a diagnosis of head trauma. The ROC curve was able to show that the ultrasound variables presented a sensitivity of 93% and specificity of 94% with an area under the curve (AUC) of 0.93. And of these (ITV, GC, Echo-pulmonary, VEXUS and IVC indices) were the ones that best predict blood volume. In our survival analysis (Kaplan Meier) we found a mean survival of 37.5 days (36.4 - 38.49) in the group (Hypovolemic = CPS), compared to a mean survival of 27.7 days (25.4 - 29.9) in the group (Normo-hypervolemic = SIADH) (CI 95% P: 0.078), which expresses higher mortality in those neurocritical patients who developed acute hyponatremia (Normo-hypervolemic = CPS).Conclusions:More than half of the neurocritical patients developed hyponatremia during their stay in the ICU, the mean age of the patients was 44 for the hypovolemic group and 35 for the normo-hypervolemic group, the predominant gender was male and most had a diagnosis of head trauma. POCUS (LUS, VEXUS, FoCUS) showed higher sensitivity and specificity in predicting blood volume in neurocritical patients with acute hyponatremia. The time to resolution of hyponatremia after starting treatment was a median of 3 days in the hypovolemic group, in contrast to the normo-hypervolemic group, which required more time, and no cases of overcorrection were reported in either group. Neurocritical patients with acute hyponatremia (Hypovolemic = CPS) would have more days of survival compared to neurocritical patients with acute hyponatremia (Normo-hypervolemic = SIADH)

Synthesis of triclosan-derived coumarins as potent, biocompatible, broad-spectrum antimicrobial agents
Authors: Alshaher Marwa Mohammed , Mustafa Yasser Fakri 
Published: December 2024

Objective: Various personal care products previously used triclosan, a chlorinated antimicrobial agent. However, safety and environmental concerns have grown, forbidding its application. Given this fact, the present work aims to repurpose this out-of-use chemical by including it as a precursor for synthesizing nineteen triclosan-based coumarins (TBCs). Methods: The spectrophotometric methods applied to confirm the chemical structures of TBCs were FTIR, 1H-NMR, 13C-NMR, and HRMS. The antimicrobial investigations were run through using broth microdilution methodology and many pathogenic microbes. These include six aerobic and four anaerobic ATCC-approved bacterial strains, as well as two fungal strains. We validated the results by comparing them with three standards: ciprofloxacin, metronidazole, and nystatin, which were based on the tested microbe. On the other hand, the biocompatibility investigations determined the ability of TBCs to inhibit the normal growth of three microbiome strains. Results: The results revealed several conclusive points, including the bactericidal impact of the synthesized TBCs on both pathogenic and microbiome strains tested, with low and high MIC values, respectively. The impact of the synthesized TBCs on pathogenic bacteria was dependent on the number and type of substitutes on the D ring, but this was not the case for microbiome bacteria, where these two factors were of low importance. These factors also influence the activity of the synthesized TBCs against pathogenic fungi. The latter microbes exhibit a high level of sensitivity to the synthetic intermediate, which contains a carboxylic acid moiety within its structure. We concluded from these findings that the number of chlorides that deactivated the D ring directly promoted the anti-aerobic bacterial activity. The same holds true for the anti-anaerobic bacteria, albeit with the addition of nitro groups. Conclusion: the results could provide insights into how the structure of the synthesized TBCs influences their antimicrobial activity. This renders them highly promising as potential future medicines that are robust, safe, and effective against a broad spectrum of microbes.

Published: December 2024

En los últimos años se viene desarrollando una corriente de investigación sobre aspectos sociales involucrados en las prácticas matemáticas. Prestar atención al contrato social supone reflexionar sobre un tema que ‘no se ve’, o que acostumbra a no verse, en el aula. Por ejemplo, ¿Quién es capaz de decir que el alumno que divide usando el algoritmo que nosotros conocemos es superior al alumno que divide usando un algoritmo alternativo igualmente correcto? Reflexionar sobre el contrato social que se establece en clases de matemáticas es el objetivo de este artículo.
