Temporal Data Simulation and Drift-Resilient Machine Learning in Cardiovascular Disease Management: A Technical Analysis
Authors: Vikas Nelamangala
Published: February 2025

Cardiovascular diseases remain a leading cause of death globally, necessitating advanced tools for effective prediction, prevention, and management. Machine learning has emerged as a transformative approach in healthcare, offering solutions for risk assessment, disease progression modeling, and personalized treatment recommendations. However, the performance of ML models often deteriorates over time due to data drift—shifts in data distributions, relationships between variables, or diagnostic thresholds—posing significant challenges in dynamic healthcare environments. This article explores methods for simulating temporal data and designing machine learning infrastructures resilient to data drift, focusing on their applications in CVD management. The article examines techniques including Autoregressive Integrated Moving Average, Hidden Markov Models, and adaptive learning strategies for modeling evolving trends in cardiovascular metrics. To address data drift, the paper highlights strategies for detecting and mitigating its effects on model performance through comprehensive monitoring frameworks and validation protocols. Additionally, frameworks for integrating simulated temporal data into ML pipelines, including automated retraining workflows and continual learning systems that maintain model robustness, are reviewed. These approaches are applied in CVD to predict cardiac events, optimize treatment plans, and manage hospital resources. Ethical considerations, such as fairness in simulated datasets, privacy protection, and practical implementation challenges, are also discussed.

The data used in this study were from published article reporting body weight report of native crossbred chickens from natural mating between the male Sentul (SC) breed and the female Kampung chicken breed (KC). The NCC body weight (BW) was recorded weekly from 1 to 12 weeks. Three non-linear growth curve models (Gompertz, Logistic, and Weibull) were used to model NCC growth performances. The best-fit model was measured with a coefficient of determination (R2), adjusted coefficient of determination (AdjR2), and root mean square error (RMSE). The results showed that Gompertz models (R2: 0.97, 0.96; AdjR2: 0.97, 0.96; RMSE: 18.89, 13.63 for males and females, respectively) were more favorable. Age at inflection ranged from 9.29 to 11.30 weeks for males and 9.12 to 11.13 weeks for females, respectively. Estimated weights at inflection ranged from 686.13 g to 920.40 g for males and 553.46 to 742.09 g for females. In conclusion, the Gompertz model is the most suitable model for describing the growth curve of native crossbred chickens.

Published: February 2025

Forage is a very important element for livestock development as they need it to survive, produce and reproduce. The forages that is often used is panic grass (Panicum maximum) which is a feed grass from the African plains, widely used in various regions of Indonesia. This grass is used for their high nutritional value, the ability to adapt various types of soil and weather, and usage as an ideal or high quality “cut and carry” grass for beef and dairy cattle. Forage cultivation by considering plant genetics can improve the quality of all types of forage inherited from the parent hence increase the productivity of feed crops and support livestock development. This can be done with molecular marker, which is a technology that can confirm target genes effectively, efficiently and accurately and are not influenced by environmental factors. Among the markers or molecular markers currently available, microsatellites or Simple Sequence Repeats (SSR) have become a marker system that is commonly used because of its various advantages, namely that it can be amplified by Polymerase Chain Reaction using primers that combine sequences in the target DNA. In this research, genes that carry leaf-rolling, plant height, and fertility-restoring properties that have previously been identified in rice plants will be tested on panic grass using RM20A, RM241, RM315. After being visualized using electrophoresis gel, it can be concluded that RM241 had the best result as it has clear amplification result and polymorphic bands with effectiveness and polymorphism levels of 75% and 100% respectively.

Published: February 2025

The problem of multicollinearity among independent variables in a regression model was addressed in this study using Partial Least Squares (PLS) and Principal Component Analysis (PCA). The influence exerted by multicollinearity can deteriorate the results of regression modeling; that is, it makes the traditional technique OLS less reliable. The research is centered on applying advanced algorithms for Partial Least Squares (SIMPL and O-PLS) as well as for PCA (NIPALS and SVD) on real-life data scenarios, as well as integrating genetic algorithm (GAs) with these algorithms to optimize predictive performance.
The relative efficiency of these methods is evaluated primarily through the amplitude of the Mean Square Error (MSE) used as a criterion for comparison. The results show the effectiveness of PLS-OPLS above PCA in terms of the lowest before and after embedding genetic algorithms into the MSE. All this underpins the effectiveness of PLS in minimizing multicollinearity thereby allowing for the formulation and prediction of very highly predictive models.
More and more indication of subtle class was revealed with regard to fine tuning advanced GA technique in favor of enhancing regression modeling for complex data analysis. The ongoing research will help in opening numerous possibilities to reinforce regression methodology, especially when one factor in an array of applications representing a relatively significant level of prediction accuracy.

Objective: The correlation between left atrial (LA) enlargement and obesity has been previously reported. However, most studies primarily evaluated LA diameter using echocardiography, which is less accurate and reliable than assessing LA volume with cardiac magnetic resonance (CMR). This study aimed to explore the correlation between obesity and LA volume by using CMR imaging.
Materials and Methods: We prospectively enrolled consecutive eligible patients aged 18 years or older who underwent CMR at a tertiary academic hospital. Clinical variables, including body mass index (BMI), were collected from the medical records. LA volume classification was based on the current guideline recommendations.
Results: A total of 140 patients (41% men), with a mean age of 66.5 ± 10.5 years, were studied. The mean BMI was 25.7 ± 4.2 kg/m2. CMR parameters revealed an LA volume of 75.7 ± 22.5 mL, a left ventricular (LV) ejection fraction of 71.1 ± 9.5%, and an LV mass index of 46.1 ± 27.4 g/m2. Univariable analysis indicated that the factors affecting LA volume included BMI (r = 0.3, p < 0.001), LV mass index (r = 0.3, p = 0.001), waist circumference (r = 0.3, p < 0.001), male sex (p = 0.01), and hypertension (p = 0.01). In stepwise multivariable analysis, BMI (p < 0.001), LV mass index (p = 0.02), and male sex (p = 0.03) were independently associated with LA volume.
Conclusion: Obesity, as represented by BMI, was independently associated with LA enlargement. Other independent factors correlated with LA volume included the LV mass index and male sex.

Background: Emphysematous pyelonephritis (EPN) is an uncommon, acute and severe necrotizing infection affecting the renal parenchyma, collecting system and surrounding tissues. This study was planned to describe the demographic, clinical, laboratory and imaging characteristics and in-hospital outcomes of patients with EPN. Methods: This retrospective study was done at BIRDEM General Hospital, Dhaka, Bangladesh between 2021 and 2023. Patients’ clinical, laboratory and imaging characteristics and in-hospital outcomes were recorded in case record forms at the time of discharge or death, if were any. Results: Total patients were 16 with female predominance (10, 62.5%). Mean age of patients was 57.1 (range 29 - 67) years. Risk factors for EPN were diabetes mellitus (16, 100%) and renal stones (3, 18.8%). Fever (16, 100%), loin pain (11, 68.8%), vomiting (10, 62.5%) and dysuria (10, 62.5%) were common presenting features. All (16, 100%) patients had leukocytosis and uncontrolled blood glucose (HbA1c >7%). Complications included acute kidney injury (AKI) (7, 43.8%), hyponatremia (5, 31.3%) and bacteremia (3, 18.8%). Escherichia coli (11, 68.8%) was the most common urinary isolate. Most patients (11, 68.8%) had class 2 EPN, 3 (18.8%) had class 3B and 1 (6.3%) had class 3A disease. One (6.3%) patient had class 4 EPN with emphysematous cystitis. Along with medical management, four (25%) patients required surgery (open drainage in 3, open drainage with double J stenting in 1). None required nephrectomy. Mean hospital stay was 8 (range 6 - 11) days and there was no death. Conclusion: EPN occurred predominantly among female diabetic patients with poor glycemic status, who presented with fever, loin pain, vomiting and dysuria. Two-fifths of patients had AKI and one-fourth required surgery. None required nephrectomy and there was no mortality.

Published: February 2025

Background: Capillarization of sinusoids occur in hepatocellular carcinoma (HCC) and several studies showed these altered sinusoids become immunoreactive for CD34. HCC and some non-malignant hepatic nodules mimic microscopically. The aims of this study were to find out the location and pattern of CD34 expression in HCC and non-malignant hepatic nodules and to see whether CD34 expression can differentiate them. Methods: This cross-sectional study was conducted in the Department of Pathology, BIRDEM General Hospital, Dhaka from March 2020 to February 2022. Thirty-one cases of HCC and 31 cases of non-malignant hepatic nodules were included in this study. Detail microscopic examinations were done regarding HCC, its morphological type, grade, cirrhosis, dysplasia and of other type of non-malignant hepatic nodules. Immunohistochemical staining of CD34 was performed in all cases. Results: No sinusoidal expression of CD34 was found in normal hepatic tissue. In benign hepatic nodules, sinusoids showed none to up to 20% areas of sinusoidal expression with +/++ intensity. HCC showed expression of CD34 in more than 50% areas with an intensity of +++ irrespective of grade and morphological type. Extent of CD34 expression increased significantly with the increasing grade of tumor. In cirrhosis, CD34 expression significantly increased in dysplastic than non-dysplastic cirrhotic nodules. Conclusion: The extent of expression became significantly increased from low grade dysplasia and more significantly increased in HCC than non-malignant hepatic nodules.

Published: February 2025

An experiment was conducted at the Advanced Plant Breeding and Tissue Culture Laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University to evaluate the effects of NaCl on rice callus induction and plant regeneration, along with genetic variability assessment through molecular markers. Dehusked seeds of five distinct rice genotypes (Dakshahi, Gondhakasturi, Guamasuri, Duksail, and Khazar) were put on MS medium supplemented with five levels (0, 0.2, 0.4, 0.6 and 0.8%) of NaCl. Developed calli were placed in MS medium for regeneration around 3-6 weeks later. Callus induction and plant regeneration declined with the increase of salinity levels. Dakshahi outperformed the other cultivars in both parameters at different salt concentrations, and it was the only cultivar with callus and regenerated plants at 0.08% NaCl concentrations. To amplify the genomic DNA of parents and somaclones of different varieties, five random amplified polymorphic DNA (RAPD) primers were used. Polymorphic bands were visible in OPD-07 primer. Dakshahi and Khazar were found to have the maximum genetic diversity (0.941). The genetic similarity coefficients between lines demonstrate that the degree of genetic diversity within rice genotypes was quite distinct. The cluster analysis grouped five genotypes into two clusters. The presence of genetic variation in the somaclones of Guamasuri implies the potential of RAPD markers in assessing genetic diversity and validating somaclonal variation. Also, Dakshahi demonstrating the highest tolerance for NaCl stress in both callus induction and plant regeneration, making it a promising candidate for salt-tolerant rice breeding in future.

Patients with chronic kidney disease (CKD) have a high prevalence of vitamin D deficiency; such a deficiency can exacerbate the CKD and related complications. The population in Bangladesh gets exposure to sunlight radiation; however, levels of vitamin D levels could be affected due to factors like skin color, dressing etiquette, etc. This cross-sectional study was done in Community Based Medical College, Bangladesh (CBMC,B) Hospital, from January 2021 to January 2022, to determine the prevalence vitamin D deficiency among of CKD patients and to examine association between vitamin D and CKD classification. A total of 120 patients who had been diagnosed with CKD (stages 3-5) were included in this study. Data on age, gender, past medical history, and blood samples for serum creatinine and 25-hydroxyvitamin D levels were obtained. The eGFR was estimated from the CKD-EPI formula. Serum (>30 ng/mL) levels were classified into a normal range, which was greater than 30 ng/mL, insufficient, between 10 and 30 ng/mL, and deficient if lower than 10 ng/mL. The mean age of the study participants was 53.25±7.6 years, with 66.7% male. Vitamin D deficiency was found in 25% of patients, while 35.8% had insufficiency. A significant inverse relationship was observed between CKD stages and mean vitamin D levels (p<0.00001). Mean vitamin D levels decreased from 33.53±6.24 ng/mL in stage 3a to 12.36 ± 3.43 ng/mL in stage 5. Our study gives an indication that vitamin D deficiency and insufficiency are considerable among the CKD patients in Bangladesh, and it correlates significantly with the severity of kidney disease. Hence, we recommend vitamin D monitoring and possibly supplementation in the context of CKD, especially in the late stages.
