Authors:   Department of Internal Medicine Sri Manakula Vinayagar Medical College and Hospital – Puducherry, Sankar M. K Dr Uthaya
Published: October 2024

Introduction: Magnesium is an essential element in functioning human body. Low magnesium is associated with membrane destabilization, whereas high concentrations are membrane stabilizing and therefore, antiarrhythmic. Acute coronary syndrome comprises of ST segment elevated myocardial infarction (STEMI), non-ST segment elevated myocardial infarction (NSTEMI) and unstable angina where the blood flow to the heart is decreased. Magnesium plays important role in Sepsis and attributed to its effects on Immune System. Hypomagnesemia is commonly observed in patients admitted to Intensive Care Unit Aim: To find the prevalence of Serum Magnesium levels with SOFA score in assessing the prognosis in Acute Coronary Syndrome patients and its associated complications. Methodology: This is hospital-based cross-sectional study. The sample size was calculated to be 77. All patients of age more than 18 years who are diagnosed to have Acute Coronary Syndromes were included in this study after screening for the exclusion criteria. After written consent, all patients were subjected into study. Clinical presentation and demographic profile and lab parameters were assessed. Results: In this study of 77 patients the mean age was 60 ± 10.8; age group between 51-70 had highest proportion of 57%. About 71.40% are male, while 29% are female. Chest pain observed in 100% of patients while palpitation seen in 98.7%. Highest proportion of comorbidity seen in Type 2 Diabetes 90%, followed by Systemic Hypertension at 64%. The majority of patients across most variables fall into the Normomagnesemia category. The differences in distribution of age, gender, comorbidities, Troponin I status, and ECG changes & SOFA score across the magnesium levels categories are not statistically significant, as indicated by the P values being greater than 0.05. These patients did not develop any arrhythmic complications. Conclusion: This study showed no significant relationship between the Serum Magnesium and SOFA score and good prognosis among patients with acute coronary syndrome. However, further studies are required to increase the understanding of the association between Serum Magnesium and SOFA score in various study settings to diagnose the patient earlier and take necessary preventive measures and treatment to prevent the occurrence of complications. Keywords: Acute coronary syndrome, Serum Magnesium, SOFA score, Normomagnesemia

Introduction: Acute coronary syndrome is a spectrum of disease consisting of ST segment elevated myocardial infarction (STEMI), non-ST segment elevated myocardial infarction (NSTEMI) and unstable angina where the blood flow to the heart is decreased. According to WHO, India contributes to one-fifth of the world's deaths due to cardiovascular disease. In recent times, the RDW has been used as a helpful marker in the diagnosis and prognosis of patients with acute coronary syndrome. However, the relationship between RDW, HDL-C, and ACS has yet to be identified properly. Aim: To evaluate the association between HDL-C levels and the RDW among patients with ACS and to find its association with the various socio-demographic factors of the patient. Methods: This hospital-based cross-sectional study was conducted in a tertiary care hospital in Puducherry between October 2023 and February 2024. Patients aged more than 18 with a diagnosis of acute coronary syndrome were included in the study. All the patients were subjected to a complete history followed by laboratory investigations, including the RDW, HDL-C, and troponin-I. Results: A total of 62 patients participated in the study. The mean age of the patients with ACS was found to be 55.6 + 3.4 years. The study didn’t show any association between the age (p=0.753), gender (p=0.897), residence (p=0.517), Type-2 DM (p=-.924), hypertension (p=0.615), dyslipidemia (p=0.302), smoking (p=0.565), alcohol (p=0.593), ACS type (p=0.714), Troponin-I (p=0.916), HDL-C (p=0.517) and RBS (p=0.078) with the level of the RDW. However, the study showed a significant association between BMI and RDW levels (p<0.001), and there is a significant and negative correlation was noted between the RDW and HDL-C levels (p=0.038). Conclusion: The study showed a significant and negative correlation between the HDL-C and the RDW among patients with acute coronary syndrome. The study recommends that the RDW be used as an additional marker in predicting the risk of ACS and diagnosing patients with ACS. Keywords: acute coronary syndrome, RDW, HDL-C, demographic factors.
Therapeutic benefits of incretin hormones beyond glycemic control from a primary care perspective: A Narrative Review
Authors:   Family Medicine, Primary Health Care Corporation, Doha, Qatar, Amin Fatma Abubakar
Published: October 2024

The parallel rise in the prevalence of obesity and T2DM is a global health challenge. One of the pathogenesis involved in development and progression of type-2 diabetes mellitus is beta cell dysfunction. Until now, diabetes treatments could not restore the reduced function of pancreatic β cell, necessitating the need for advanced treatment options. This led to discovery of incretin hormones in the small intestine, which stimulates insulin secretion in response to glucose. Glucagon-like peptide 1 (GLP-1) and glucosedependent insulinotropic polypeptide (GIP) are two such incretin hormones, secreted by the small intestine in response to food ingestion. Important physiological effects of GLP-1 include enhancement of the insulinotropic response of beta cells to intake of nutrients, reduced gastrointestinal secretion and motility, as well as induction of satiety and ensuing reduction of food intake. Recent evidence suggests that in addition to its established glucose-lowering actions, GLP-1 RAs may also exert several beneficial actions extending beyond glycemic control. The recent finding that GIP/GLP-1 receptor co-agonists like tirzepatide have superior efficacy compared to selective GLP-1 receptor agonists with respect to glycaemic control as well as body weight has renewed interest in GIP, which previously was thought to lack therapeutic potential. This is a narrative review examining some of the ‘beyond-glycemic” benefits of incretin hormones, focusing predominantly on GLP-1 RAs including blood pressure lowering, improvements in the lipid profile, improvements in myocardial and endothelial function. We explore how those effects may help reduce the cardiovascular burden in patients with diabetes. The aim is to encourage use of GLP-1 RA early in patients with established CVD risk factors to prevent CVD related complications and mortality. Keywords: glucagon-like peptide-1 receptor agonist, cardiovascular diseases, major adverse cardiovascular events, type 2 diabetes mellitus, obesity, GIP receptor.

Background: Mongolia was classified as one of the 30 countries with the highest tuberculosis burden by World Health Organization in 2021 and tuberculosis is the first leading cause of mortality among deaths from all communicable diseases in the country. The number and distribution of health workers to provide tuberculosis healthcare services will play an important role in the fight against tuberculosis. However, there has been no quantitative evaluation of the distribution of tuberculosis health workers in Mongolia. Therefore, this study aimed to examine the distribution of health workers in the tuberculosis sector using the Gini index. The results provide quantifiable information for monitoring resource distribution and serve as a basis for informed decision-making on resource allocation, facilitating targeted interventions and equitable healthcare distribution in Mongolia.
Methods: Data from the National Center for Communicable Diseases and the National Statistical Information Service of Mongolia was obtained and analyzed. The Gini coefficients were calculated to reflect the inequality of distributions.
Results: Total number of health workers in the tuberculosis sector was only 1.29 per 10,000 population. The Gini index values for the distribution of tuberculosis doctors, assistant workers, nurses, and laboratory technicians were at 0.61, 0.67, 0.43, and 0.33 respectively, all showing a range from severe to relative inequality.
Conclusions: Findings showed the number and distribution of tuberculosis health workers were both inadequate and unequal and ring the need for proper health system planning. To plan the tuberculosis control and address the high burden of the disease in the country, the human resources situation should be analyzed and handled regularly.

Aim: Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) or COVID-19 infection has been an unusual plummet in dentistry. Various measures were adopted to slow or halt the spread of COVID-19. Many countries suspended activities that are deemed “non-essential.” Several dental procedures fall into this category, and only emergencies that cannot be postponed are still allowed. Therefore, followup visits for active orthodontic treatment should be treated with special new standard precautions. This review aims to reduce orthodontic treatment appointments by providing an overview of the available methods and their purpose in patient monitoring, i.e., teleorthodontic. Methods: A total of 5 articles demonstrating the practical application of teledentistry including teleorthodontic were included. Result: Most emergencies can be handled via teleorthodontics, which can reassure and follow patients from afar. Teleorthodontics achieved its goal of reducing patient visits while keeping regular monitoring without sacrificing results. Conclusion: Teleorthodontics can handle most emergencies assist and follow up patients remotely while at their homes. It can reduce the number of patient visits while maintaining regular monitoring without compromising the results of orthodontics treatment. These findings still need further development in efficacy, cost-effectiveness, and long-term outcomes, but we believe teleorthodontics plays an essential role during the COVID-19 outbreaks.

Authors: Al-Khataneh Oraib Khaled Dojan
Published: October 2024

The academic achievement of secondary school students in Jordan is evaluated based on the use of feedback-based teaching. The learners are stimulated to correct their areas of weakness through constructive feedback. Therefore, this study presents an investigation of the impact of feedback-based teaching on student’s academic achievement. To achieve that, the study involved a total 160 students were involved in the study from 4 randomly selected private schools in Jordan, Irbid Governorate, two English classes were selected randomly from each school. The students were divided into a control group and an experimental one. The control group received regular instruction while the experimental group was taught using feedback-based teaching, where feedback was provided by the teachers in different forms. Consequently, the analysis denotes that frequent and diverse feedback is highly constructive and improves students' achievement compared to feedback that is unstructured. It is clear that feedback has to be effectively structured to ensure that it achieves its objectives in improving students’ academic achievement.
A Correlation Study Between Aerodynamic Structural Changes and Aerodynamic Noise Characteristics of Archimedes Spiral Wind Turbines
Authors: Li Baohua , Deng Zetao , Dai Yuanjun , Zhong Lei , Wang Jianping
Published: October 2024

This paper investigates the impact of aerodynamic structural changes on the aerodynamic noise of Archimedes spiral wind turbines (ASWTs) using experimental and numerical research methods. Both parts of the experimental work are validated based on the prototype ASWT, with the working conditions consistent with the numerical calculation conditions. The aerodynamic noise of the ASWT before and after modification is numerically simulated by combining Large Eddy Simulation (LES) with the Ffowcs Williams-Hawkings (FW-H) method, which converts internal flow field information into acoustic field information. The results demonstrate that the improved ASWT exhibits reduced high-frequency discrete noise in the 400 to 1000 Hz range at $TSR=2$. Specifically, the Sound Pressure Levels (SPLs) of the quadrupole noise source near 471 Hz and 671 Hz for the prototype ASWT are 100.15 dB and 112.90 dB, respectively, while the corresponding SPLs near 471 Hz and 679 Hz for the retrofitted ASWT are 57.68 dB and 63.29 dB, respectively. These represent reductions of 42.47 dB and 49.61 dB, respectively. Additionally, the predicted Overall Sound Pressure Levels (OASPLs) of the ASWT at locations 8 and 9 are 16.82 dB and 38.22 dB lower before and after modification, respectively. These findings not only improve the aerodynamic efficiency of ASWTs but also lay a solid foundation for the subsequent study of their acoustic propagation characteristics. This is of significant importance for future research on wind turbine miniaturization.
An Investigation of the Effects of a Dynamic Vibration Absorber (DVA) to the Comfort of a Bus's Driver Seat
Authors: Tran Huu Nhan , Pham Ngoc Dai
Published: October 2024

The frequency weighted acceleration, relative displacement, and Seat Effective Amplitude Transmissibility (SEAT) of a bus driver's seat are investigated by a 4 degrees of freedom (4DOF) vertical dynamic model, including a dynamic vibration absorber (DVA). The Root Mean Squared (RMS) values of the gain responses in the frequency domain are analyzed in the DVA damping ratio domain to help determine the optimal value of the DVA' s suspension. The obtained results show that the comfort evaluation index, in the case of a bus driver's seat with DVA, can be improved by more than 15% and nearly 10%, respectively, with the seat suspension natural frequency of 1~Hz and 4~Hz respectively. The comfort is better with the lower seat suspension natural frequency and vice versa. Especially in the case of both the seat and the DVA suspensions with low natural frequencies, all the three mean of evaluation indexes in the whole damping ratio domain of the DVA, have improved by more than 12%. This is the case with all three evaluation indexes which are the best when the damping ratio of the DVA is greater than 0.6.
Optimization of Cooling Fan Based on Unequal Angle and Leading-Edge Triangle Blade Design
Authors: Youfu Xie , Feng Jiang
Published: October 2024

In order to reduce the noise of the axial fan, an uneven blade spacing was used to optimize tonal noise and blade leading edge triangles were added to optimize the broadband noise. First, different angular distribution schemes were designed on the basis of ensuring the dynamic balance of the fan, and the noise of the different schemes was simulated by using the computational aeroacoustics (CAA) numerical simulation method. Then, the best optimal angular distribution design was selected for experimental verification, which confirmed the reliability of the numerical calculation. The test results also show that the uneven blade spacing has little effect on the fan pressure and efficiency. Additionally, triangular leading edges were added to each blade based on the uneven blade spacing design. Combining these two optimization schemes proved to reduce the fan noise by 13.4 dBA.

Authors: Joseph Thomas , Krishnan K Keerthi , U Sudeep , Khanam Sidra
Published: October 2024

Data driven fault diagnosis methods are increasingly being used for condition monitoring of rotating machinery in the era of Industry 4.0. The effectiveness of Variational Mode Decomposition (VMD) denoised vibration signals in improving the Long Short-Term Memory (LSTM) method for the intelligent fault diagnosis of a rolling bearing is reported. The raw and VMD denoised vibration signals of rolling bearings are provided as inputs to the LSTM network for classification of bearing condition. The efficacy of the methodology to extract the fault information is assessed through datasets obtained from experiment test rig and through the open-source dataset of Case Western Reserve University (CWRU). A comparative analysis is also carried out using both VMD based decomposition and denoising techniques along with four machine learning classifiers viz. Decision Tree, k-Nearest Neighbour (k-NN), Support Vector Machine (SVM) and Artificial Neural Network (ANN) by using the statistical features of the VMD modes. Among the different methods evaluated, VMD denoised signals when fed to LSTM result in the maximum classification accuracy of 99.14 % with experimental dataset. For the case of CWRU dataset, VMD denoised signals as input to the SVM resulted in maximum classification accuracy of 98.16%.

Authors: Guo Pengcheng , Cai Sijie , Chen Shuixuan , Gao Song , Zhang Zhihua , Chen Jianyu
Published: October 2024

Milling chatter is a self-excited vibration phenomenon during the cutting process, typically occurring in machining operations with lower stiffness. It significantly impacts the machining precision and surface morphology of the workpiece. To summarize the vibration signal features under operating conditions and enhance the precision of the intelligent recognition model for milling chatter features, this paper proposes an adaptive learning model for chatter feature recognition based on the improved convolutional clustering algorithm. This study uses wavelet analysis to extract chatter features and improved convolutional clustering to identify chatter and stable cutting signals. This method selected appropriate mapping techniques based on differences in chatter signals under various conditions and uses convolution for feature extraction. Improve convolutional clustering evaluates sample similarity through energy transfer, less influenced by signal space structure compared to Euclidean or Mahalanobis distances. This method provides a unified criterion for evaluating different signal feature representation spaces, thereby improving the accuracy and efficiency of chatter sample recognition. The recognition accuracy of chatter phenomena at different spindle speed ranges reaches $95$ % and $96.3$ % respectively. The results show that this method can effectively distinguish between chatter signals and stable cutting signals.
Concepts for Frequency Sweeps and Efficient Repeated Analysis in the Context of Vibroacoustic Optimization and Uncertainty Quantification
Authors: Marburg Steffen
Published: October 2024

This paper aims at passive noise control for vibroacoustic problems, which are analyzed by finite and boundary element techniques. The author distinguishes interior and exterior problems mainly because of the quantities used as the objective function to assess the acoustic quality. For interior problems, it is common to use local quantities such as the sound pressure at a field point or, in rare cases, energy density at a field point. The situation is different for exterior problems where the radiated sound power accounts for a suitable and global quantity to assess the emission from a vibrating structure. For most engineering purposes, the assessment requires frequency sweeps in which the problem needs to be solved at many discrete frequencies. In vibroacoustic optimization and in sampling based uncertainty quantification, it is very common that structural parameters are varied, while the acoustic field remains the same throughout the entire process. We will review concepts and recent developments of efficient frequency sweeps and repeated analysis with unmodified fluid domain. For many practical cases, the situation for interior problems is rather simple to survey. Either the authors have applied a modal analysis and used a modal superposition for the frequency sweep and repeated analysis, or the concept of unmodified acoustic transfer vectors is applied. Both concepts are quite successful as long as certain conditions are fulfilled. For exterior problems, a modal superposition is possible but, so far, only for a limited number of cases practically applicable as discussed herein. The concept of using acoustic transfer vectors becomes inefficient since the evaluation of the radiated sound power asanintegral over a closed enveloping surface would require an excessively high amount of storage capacity. Therefore, other concepts are being followed. For frequency sweeps, a number of methods are using a frequency interpolation based on a limited number of discrete sample frequencies. Often, these techniques are used together with Krylov–subspace model order reduction techniques. Further recently published approaches investigate low-rank approximations, greedy algorithms, and deflated Krylov subspace techniques. A completely different kind of approach is based on multi–fidelity models and Gaussian processes. The field of efficient repeated analysis shows some interesting developments, which can be easily applied to sampling based uncertainty quantification but do not seem to be easily and generally applied to optimization.
Finding a Published Research Paper which Meaningfully Averages the Most Pathalogical Functions (V2)
Authors: Krishnan Bharath
Published: October 2024

I want to meaningfully average a pathalogical function (i.e., an everywhere surjective function whose graph has zero Hausdorff measure in its dimension). In case this impossible, we wish to average a nowhere continuous function defined on the rationals. We do this by taking the most generalized, satisfying extension of the expected value, w.r.t the Hausdorff measure in its dimension, on bounded functions with domains of finite measure, which takes finite values only. As of now, I’m unable to solve this due to limited knowledge of advanced math and most people are too busy to help. Therefore, I’m wondering if anyone knows a research paper which solves my doubts. Unlike the previous paper, “Finding a Research Paper Which Meaningfully Averages Pathalogical Functions”) we add motivations, examples, and change parts of the original paper.

N-methyl-D-aspartate receptors (NMDARs) are critical components of the mammalian central nervous system, involved in synaptic transmission, plasticity, and neurodevelopment. This review focuses on the structural and functional characteristics of NMDARs, with a particular emphasis on the GRIN2 subunits (GluN2A-D). The diversity of GRIN2 subunits, driven by alternative splicing and genetic variants, significantly impacts receptor function, synaptic localization, and disease manifestation. We explore the physiological properties and developmental regulation of these subunits, highlighting their roles in the pathophysiology of various NDDs, including ASD, epilepsy, and schizophrenia. By reviewing current knowledge and experimental models, including mouse models and human-induced pluripotent stem cells (hiPSCs), this article aims to elucidate different approaches through which the intricacies of NMDAR dysfunction in NDDs are currently being explored. The comprehensive understanding of NMDAR subunit composition and their mutations provides a foundation for developing targeted therapeutic strategies to address these complex disorders.

Mergers and acquisitions (M&A) represent pivotal moments for businesses, with the potential to unlock growth, synergies, and market power. However, the success of such transactions is heavily dependent on the robustness of the contractual agreements that define them. Poorly designed contracts introduce numerous risks that can derail the benefits of the deal, leading to financial losses, legal disputes, or operational inefficiencies. This work examines the core risks associated with inadequate contract design in M&A, supported by academic research.

The purpose of this study was to examine the relationship between demyelination and glial cell responses in the cerebellum of CDV-infected dogs. We subdivided the disease staging by adding the degree of demyelination determined by LFB staining to the previously reported disease staging from the acute stage to the chronic stage, and investigated the relationship between demyelination in cerebellum and the number and histological changes of astroglia, microglia and Purkinje cells in each stage. Reactions of astrocytes and microglia were observed at an early stage when demyelination was not evident. Changes progressed with demyelination. Demyelination initially began in the medulla adjoining the fourth ventricle and gradually spread to the entire cerebellum, including lobes. CDV immune-positive granules were seen from the early stage, and inclusion bodies also appeared at the same time. CDV immune-positive reaction and inclusion bodies were observed in astrocytes, microglia, neurons, ependymal cells, and even leptomenin-geal mononuclear cells. On the other hand, infiltration of CDV immunoreactive particles from the pia mater to the gray matter and further into the white matter through the granular layer was observed from an early stage. Purkinje cells decreased from the intermediate stage, and a decrease in cells in the granular layer was also observed. There was no clear association between age and each stage, and the stages did not progress with age.

Diabetic foot sepsis (DFS) is the leading cause of lower extremity amputations and timely initiation of effective antimicrobial therapy is paramount during its management. This study investigated causative microorganisms and their antimicrobial susceptibility profile in patients with DFS. Methods: A retrospective review was conducted on patients who were 18-years and older admitted for DFS. . Data collected included demographic: information, comorbidities, clinical findings, type of specimen collected for microbiology and microbiology results, treatment and outcomes. Data was analysed using STATA/SE version 17.0 and a p-value of 0.05 considered statistically significant. Results: Hundred and sixty-eight records were found of which 64.3% of patients were male who also had a median (IQR) age of 58 years (IQR 54-65). In comparison, females had a median age of 61 years (IQR 54-67). The microbiology results were available in 63.1% of the records and 60.4% were taken from tissue specimens (60.4%) and 14.2% from pus swabs (14.2%). Enterococcus faecalis was cultured in 16%, Proteus mirabilis 10%, and Staphylococcus aureus in 8%. Amoxicillin/Clavulanic acid was prescribed for 69% of the cases. Resistance to at least one antimicrobial was observed in 88% of Staphylococcus aureus and 80% of Proteus mirabilis species. Conclusions: Diabetic foot sepsis commonly affects males around the age of 60 years. The commonly cultured organism in patients with DFS are Enterococcus faecalis 16%, Proteus mirabilis 10%, and Staphylococcus aureus. Amoxicillin/Clavulanic acid as the primary antimicrobial therapy and in close to 40% of patients, with DFS, antimicrobial treatment is not preceded by collection of a specimen for MC&S despite high rates of resistance seen in the common cultured organisms. This data may assist with updating local guidelines so as to better manage this condition in an evidenced based way.
