Background: Reducing body weight by nutritional management is an integral element of cardiac rehabilitation and in secondary prevention of cardiovascular diseases. Administration of a "plate model" is one practical aspect to control calorie intake. The study aimed to evaluate the effectiveness of the plate model as a part of dietary modification in losing excess weight in post-myocardial infarction (MI) patients.
Methods: An interventional, randomized, single-blinded study with parallel subject allocation was conducted among patients with a history of troponin-positive acute coronary syndrome (ACS). A total of 120 patients were recruited to intervention and control groups. The Intervention cluster was provided with 'plate model' and both groups received standard cardiac rehabilitation care. Anthropometric, clinical and metabolic parameters were measured at recruitment and repeated during 4th and 12th week.
Results: A sample of 79 patients (the intervention group: 40, the control group: 39) completed the study. At the end of 12 weeks participants in the intervention group exhibited a significant weight loss (-1.27±3.58 -0.26±2.42 kg; P=0.029) and a significant reduction in BMI (-0.48±1.31 -0.10±0.89 kg/m; P=0.023). Overweight and obese patients (BMI >23 kg/m) displayed greater weight loss (-2.13±3.46 0.12±2.62 kg; P=0.013). Many of overweight and obese patients in the test group (35.7%) experienced a weight loss ≥5% compared to the control group (13.04%) which was a nearly significant result (P=0.065). No significant changes observed in other metabolic parameters.
Conclusions: Plate model is an effective dietary intervention in view of weight reduction in post-MI patients.

Background: Influenza remains a significant public health challenge, with vaccination being a substantial way to prevent it. Cell-cultured influenza vaccines have emerged to improve on the drawbacks of egg-based vaccines, but there are few studies focusing on T cell immunity with both types of vaccines. Therefore, we studied the following 2022-2023 seasonal influenza vaccines with a standard dose and high dose: cell-based (C_sd and C_hd) and egg-based (E_sd and E_hd) vaccines.

Standard-of-care influenza vaccines contain antigens that are typically derived from components of wild type (WT) influenza viruses. Often, these antigens elicit strain-specific immune responses and are susceptible to mismatch in seasons where antigenic drift is prevalent. Thanks to advances in viral surveillance and sequencing, influenza vaccine antigens can now be optimized using computationally derived methodologies and algorithms to enhance their immunogenicity.

Electrocardiogram (ECG) signals contain complex and diverse features, serving as a crucial basis for arrhythmia diagnosis. The subtle differences in characteristics among various types of arrhythmias, coupled with class imbalance issues in datasets, often hinder existing models from effectively capturing key information within these complex signals, leading to a bias towards normal classes. To address these challenges, this paper proposes a method for arrhythmia classification based on a multi-branch, multi-head attention temporal convolutional network (MB-MHA-TCN).

With the escalating threat posed by network intrusions, the development of efficient intrusion detection systems (IDSs) has become imperative. This study focuses on improving detection performance in programmable logic controller (PLC) network security while addressing challenges related to data imbalance and long-tail distributions. A dataset containing five types of attacks targeting programmable logic controllers (PLCs) in industrial control systems (ICS) was first constructed.

This work focuses on the preparation and application of silver nanoparticles/organophilic clay/polyethylene glycol for the catalytic reduction of the contaminants methylene blue (MB) and 4-nitrophenol (4-NP) in a simple and binary system. Algerian clay was subjected to a series of treatments including acid treatment, ion exchange with the surfactant hexadecyltrimethylammonium bromide (HTABr), immobilization of polyethylene glycol polymer, and finally dispersion of AgNPs. The molecular weight of polyethylene glycol was varied (100, 200, and 4000) to study its effect on the stabilization of silver nanoparticles (AgNPs) and the catalytic activity of the resulting samples.
