Background: The incidence and mortality rates of cardiovascular disease worldwide are a major concern in the healthcare industry. Precise prediction of cardiovascular disease is essential, and the use of machine learning and deep learning can aid in decision-making and enhance predictive abilities. Objective: The goal of this paper is to introduce a model for precise cardiovascular disease prediction by combining machine learning and deep learning. Method: Two public heart disease classification datasets with 70,000 and 1190 records besides a locally collected dataset with 600 records were used in our experiments. Then, a model which makes use of both machine learning and deep learning was proposed in this paper. The proposed model employed CNN and LSTM, as the representatives of deep learning models, besides KNN and XGB, as the representatives of machine learning models. As each classifier defined the output classes, majority voting was then used as an ensemble learner to predict the final output class. Result: The proposed model obtained the highest classification performance based on all evaluation metrics on all datasets, demonstrating its suitability and reliability in forecasting the probability of cardiovascular disease.

Coronary artery disease (CAD) is a common problem amongst diabetic foot syndrome (DFS) patients, associated with peripheral arterial disease. This analytic cross‐sectional study investigates the diagnostic efficacy of the Toe Brachial Index (TBI) in the detection of CAD in 62 DFS patients. The presence of CAD was assessed by longitudinal strain echocardiography, a sensitive method that provides a more accurate measure of intrinsic left ventricular contractility than left ventricular ejection fraction, especially in diabetic patients. Univariate and multivariate logistic regression identified CAD‐associated factors. Receiver operating characteristic curve evaluated TBI and toe pressure's diagnostic performance for CAD. p‐Values < 0.05 were considered significant. There was a significant association between TBI and CAD, with each 0.01 increase in TBI associated with a 15% decrease in the odds of CAD development (odds ratio = 0.85, 95% CI: 0.72–0.99, p = 0.039). TBI demonstrated an area under the curve of 0.854, a sensitivity of 80.0% and a specificity of 66.7% at a cut‐off of 0.69. Additionally, toe pressure exhibited an area under the curve of 0.845, sensitivity of 74.0% and specificity of 75.0% at a cut‐off of 68.0 mmHg. Overall accuracy for TBI and toe pressure was 77.4% and 74.2%, respectively, indicating their potential for CAD risk stratification in the DFS population. This study highlights a significant association between low TBI and the presence of CAD in DFS patients. Consequently, TBI emerges as a valuable screening tool for identifying CAD within this population. [ABSTRACT FROM AUTHOR]

Background & Objective: Besides the clinical and laboratory research on the COVID-19 virus, the bioinformatics study in the field of genetics of immunity to COVID-19 is of particular importance. In this account, studies show that in patients with COVID-19, the level of tumor necrosis alpha (TNFα) and interleukin-6 (IL-6) is high and in severe cases of COVID-19, the production of IL-6, TNF-α, and other cytokines increases profoundly. On the other hand, investigating the molecular structure and receptors of IL-6 and TNFα and the structural analysis of the receptor proteins may potentially help to develop new therapeutic plans for COVID-19 infection. Methods: To identify genes with significant and different expressions in patients with COVID-19 in a microarray data set containing transcriptional profiles from GEO as a functional genomic database the GEO query package version 2.64.2 in a programming language R version 4.2.1 was downloaded. In this way, functional enrichment analysis for DEGs, WikiPathways, REGO, gene ontology, and STRING database was also investigated and employed. Results: The structure and function of pro-inflammatory cytokines TNFα and IL-6 involved in the pathogenesis of COVID-19 were investigated, and in general, after performing various analyses in this study and extracting A series of genes with different expressions from the KEGG database, the final 5 DEGs include CXCL14, CXCL6, CCL8, CXCR1, TNFRSF10, and the relationship and expression effects of them were observed in different pathways. Conclusion: IL-6 and TNFα were involved in immunological processes that had a direct and indirect relationship with the activation of cytokines, including IL6 and TNF-a, and cytokine storm, and this indicates their role in the formation of problems and complications, including ARDS, in COVID-19 patients. Of course, determining the effectiveness of each of these genes requires more specialized and clinical studies. [ABSTRACT FROM AUTHOR]

Diabetic foot ulcers (DFUs) pose a significant clinical challenge, often leading to amputations and hospitalisation. This study aimed to investigate the characteristics and outcomes of DFUs treated with surgical debridement and standardised wound care. This descriptive cross‐sectional study focused on diabetic patients with appropriate vascular conditions, as determined by an Ankle Brachial Index >0.9. Based on their infection status, participants were admitted to Poursina Hospital in Rasht, Iran, and subjected to initial supportive measures, antibiotic therapy and surgical debridement. The study incorporated primary treatment with wet bandages, silver spray and fibrinolysin ointment. Statistical analysis employed SPSS 22 software. Most patients were male (54.7%) and under 60 years old (50.7%). Overweight status was prevalent in 69.3% of diabetic ulcer patients, amongst whom 48% underwent wrist debridement. The 64% and 36% of the cases had grade III and grade II Texas index. Moreover, 96% of patients exhibited signs of infection and were classified as Stage Texas B. Reoperation was necessary for 34.7% of patients. The mean hospital stay was 8.5 ± 7.55 days, and the average recovery time was 15.2 ± 15.19 days. Out of 75 patients, 10 were unable to return to limb function due to disability. In this study, around one‐third of patients required secondary repair with grafts and flaps. A small number of them were unable to recover because of underlying disability, and the mean recovery time in other cases was 24 days. Future studies should follow up with patients for longer periods to assess long‐term therapeutic outcomes and quality of life. [ABSTRACT FROM AUTHOR]

Optimal management of burns begins with first aid from the first hours of injury. Adequate knowledge of how to perform first aid for burns can reduce the consequences of injury. Therefore, this study aims to determine the knowledge, attitude, and sources of information assessment towards burn First aid among people referred to a burn centre in the north of Iran. A questionnaire‐based survey was conducted to assess knowledge, attitude, and sources of information towards burn first aid among people referred to a burn centre in the north of Iran in 2023. In this survey, a convenience sampling method was adopted. The variables consisted of four items on socio‐demographic information, 15 items on knowledge, ten items on attitude, and one item on sources of information related to burn First aid. A total of 371 individuals responded to the survey. The mean age of participants was 31.90 ± 8.49 years old. The mean score of the total knowledge of the participants in the research was 6.04 ± 3.05. There was a statistically significant relationship between the variables of age, sex, marital status, place of residence, level of education, and history of receiving first aid training with the participants' knowledge level. The average score of the total attitude of the participants was 44.08 ± 3.88. Out of 371 participants, 214 people (57.7%) had an average attitude, and 157 people (42.3%) had a good attitude towards burn first aid. There was a statistically significant relationship between place of residence, level of education, and history of receiving first aid training with the participants' attitudes in the research. In addition, the level of knowledge had a statistically significant relationship with the participants' attitude level in the research (p‐value <0.001). The majority of participants have limited knowledge of burn first aid. This lack of knowledge could lead to severe consequences. Therefore, healthcare organizations should review and promote consistent guidelines for burn first aid to tackle and minimize the effect of this grave injury. [ABSTRACT FROM AUTHOR]
