Cardiovascular diseases are the leading cause of mortality worldwide. In 2021, an estimated 48 million individuals in Latin America were living with heart and circulatory diseases. In the context of liver transplantation, cardiometabolic risk factors play a crucial role not only during the procedure but also in the long-term post-transplantation period, significantly impacting patient survival and recovery. This study analyzes a cohort from the National Liver Transplantation Program of Uruguay, employing machine learning to predict the occurrence of post-transplant cardiometabolic diseases based on pre-transplant health indicators. Over a five-year period, multiple machine learning models were evaluated, with the Extra Trees algorithm achieving the highest predictive accuracy of 88% (AUC: 0.94). The findings highlight the potential of predictive analytics in improving early risk assessment and preventive strategies, ultimately enhancing the prediction of patient outcomes in liver transplantation.Clinical Relevance— This is the first national-level study validating machine learning algorithms for cardiometabolic risk prediction in liver transplantation patients within the National Liver Transplantation Program in Uruguay. By leveraging pretransplant clinical data, the proposed model provides a data-driven approach for early risk stratification, supporting clinicians in making informed decisions to mitigate post-transplant cardiometabolic complications.
Clinical Decision Support Systems (CDSS) based on machine learning offer a promising approach to improve decision-making in nephrology by enabling predictive insights from complex clinical data. In this work, we present a modular, web-based CDSS that automates the machine learning pipeline, including data ingestion, preprocessing, model training, feature selection, and evaluation. The system supports both categorical and continuous outcomes and dynamically adapts the workflow based on the input data structure and selected target variable. The platform was applied to a real-world dataset of 854 hemodialysis patients from Uruguay, with the objective of predicting treatment discontinuation outcomes—specifically distinguishing between patients who continued treatment and those who died. Following class balancing and variable selection, a total of 36 model configurations were evaluated using cross-validation. Performance was assessed using metrics like accuracy, F1 score, Area Under the Curve (AUC), confusion matrices, and ROC analysis. Models such as logistic regression and random forests demonstrated robust classification performance, with several configurations achieving AUC values above 0.72. Consistently selected predictive features included vascular access type, pre- and post-dialysis body weight, and specific clinical markers. The system also enabled interactive prediction on new input instances, ensuring reproducibility and transparency in the decision process. The results demonstrate the applicability of the proposed CDSS in nephrology, supporting early identification of high-risk patients and contributing to improved care planning in dialysis programs.
Liver transplantation is the ultimate therapeutic option for patients with end-stage liver disease. The clinical management of transplant patients significantly impacts their prognosis, with outcomes influenced by multiple interacting variables. Cardiovascular complications count as a leading cause of both short-term and long-term morbidity and mortality in liver transplant recipients. In this respect, accurate risk assessment and stratification are crucial for optimizing clinical outcomes. Modern artificial intelligence (AI) techniques have significant potential for early risk prediction, providing comprehensive risk assessments in both diagnosed cohorts and early clinical phase patients. This systematic review examines the state of the art in AI applications for predicting cardiovascular risks in liver transplantation, identifying current issues, challenges, and future research directions. We reviewed articles from digital repositories such as PubMed, IEEE Xplore, and ScienceDirect published between 2000 and 2023, using keywords including artificial intelligence, machine learning, cardiovascular, and liver transplantation. Our analysis revealed a diverse range of machine learning algorithms used in this domain. Despite the potential, only 12 papers met the criteria for adequate topic coverage, highlighting a scarcity of research at this intersection. Key challenges include integrating diverse datasets, isolating cardiovascular effects amid multifaceted influences, ensuring data quality and quantity, and the issues to extrapolate machine learning models to day-to-day clinical practice. Nevertheless, leveraging AI for risk prediction in liver transplantation could significantly enhance patient management and resource optimization, indicating a shift towards more personalized and effective medical practices.

INTRODUCTION: Arterial wall viscosity is a source of energy dissipation that takes place during mechanical transduction. In our previous studies, a "global" damping effect in endurance training athletes was introduced, verifying that endurance-athletes dissipate greater pulsatile energy in the circulation compared with healthy untrained subjects. OBJECTIVE: To investigate the wall energy dissipation in the vascular bed for each beat and within the conceptual framework of ventricular-arterial coupling, in order to elucidate if different types of training could lead to differentiated levels of cardiovascular energy dissipation. MATERIALS AND METHODS: Data from subjects with different kinds of training (soccer players and ballet dancers) have been collected noninvasively and compared with a control group of untrained individuals to analyse the differentiating characteristics of the subjects, especially in terms of Stroke Work Dissipation (WDIS). RESULTS: In the endurance-trained individuals, an enhanced WDIS has been observed compared to the untrained individuals (p<0.05). However, non-significant differences were found regarding ballet-dancers group. CONCLUSION: Changes in wall energy dissipation are developed under high intensity endurance training routines.

Cheiloscopy is a technique of forensic investigation with the purpose of identifying humans based on their lip prints. Analyzing the lip prints in detail, detailed characteristics could be deciphered, establishing a unique link with a specific person, thus helping in identification in persons using lip prints. Machine learning has significant applications in this forensic identification process with cheiloscopy, spanning from data collection to intelligent analysis. In this work, a design for a forensic decision support system has been proposed, aimed at identification of persons in terms of their biological sex based on cheiloscopy. In this respect, a generalized architecture for the implementation of cheiloscopy has been presented, along with the predictive modeling with lip prints using supervised algorithms, which has illustrated reasonable accuracy in identifying persons in terms of their biological sex.
In the field of agriculture, there are many individual micro businesses with low investment capacity and awareness of IT utilization, and it is difficult to obtain a return on investment. In recent years, edge computing and Artificial Intelligence (AI) technologies have attracted a lot of attention in the agricultural industry to cover the labor shortage. Also, safer vegetables are required by peoples due to COVID-19 epidemic and radioactive pollution. In this paper, we propose an agricultural support system called VegeCareAI for agricultural workers. The proposed system supports vegetable classification, plant disease classification and insect pest classification to improve the crops’ productively. The support system can show the growth condition of vegetables. When there are some problems, the VegeCareAI presents information on how to deal with diseases and insect pests. From the results, we found that our proposed VegeCareAI tool has advantage for supporting several crops. For vegetable classification, our training data for 300 epochs predicted six kinds of vegetables correctly. For plant disease classification, for 400 epochs the accuracy is more than 96% accuracy for both potato and corn leaves. For insect pest classification, the accuracy of corn insect pests is more than 73%, but the results of different life cycles showed low classification accuracy, which present a future challenge.
Liver transplantation is the last therapeutic option in patients with end-stage liver diseases. The adequate clinical management of transplant-patients impacts their vital prognosis and decisions on many occasions are made from the interaction of multiple variables involved in the process. This work is based on the National Liver Transplantation Program in Uruguay. We performed predictive analysis of cardiometabolic diseases on the transplanted cohort between 2014 and 2019, considering vascular age as a key factor. This aims at classification of the cohort based on the vascular age of the evaluated patients before transplantation for risk-profiling. Predicted high-risk group of the patients showed substantial deterioration of post-transplant health-conditions, including higher mortality rate. In our knowledge, this is the first study in Latin America incorporating vascular age toward predictive analysis of cardiometabolic risk factors in liver transplantations. Predictive risk-modeling using vascular age in a pre-transplantation scenario provides significant opportunity for early prediction of post-transplant risk factors, leading to efficient treatment with anticipation.
