Extending the protection ability and life cycle of medical masks through the washing process
Julija Volmajer Valh, Tanja Pušić, Mirjana Čurlin, Ana Knežević, 2023, izvirni znanstveni članek

Opis: The reuse of decontaminated disposable medical face masks can contribute to reducing the environmental burden of discarded masks. This research is focused on the effect of household and laboratory washing at 50 °C on the quality and functionality of the nonwoven structure of polypropylene medical masks by varying the washing procedure, bath composition, disinfectant agent, and number of washing cycles as a basis for reusability. The barrier properties of the medical mask were analyzed before and after the first and fifth washing cycle indirectly by measuring the contact angle of the liquid droplets with the front and back surface of the mask, further by measuring air permeability and determining antimicrobial resistance. Additional analysis included FTIR, pH of the material surface and aqueous extract, as well as the determination of residual substances—surfactants—in the aqueous extract of washed versus unwashed medical masks, while their aesthetic aspect was examined by measuring their spectral characteristics. The results showed that household washing had a stronger impact on the change of some functional properties, primarily air permeability, than laboratory washing. The addition of the disinfectant agent, didecyldimethylammonium chloride, contributes to the protective ability and supports the idea that washing of medical masks under controlled conditions can preserve barrier properties and enable reusability.

A VAN-Based Multi-Scale Cross-Attention Mechanism for Skin Lesion Segmentation Network
Shuang Liu, Zeng Zhuang, Yanfeng Zheng, Simon Kolmanič, 2023, izvirni znanstveni članek

Opis: With the rise of deep learning technology, the field of medical image segmentation has undergone rapid development. In recent years, convolutional neural networks (CNNs) have brought many achievements and become the consensus in medical image segmentation tasks. Although many neural networks based on U-shaped structures and methods, such as skip connections have achieved excellent results in medical image segmentation tasks, the properties of convolutional operations limit their ability to effectively learn local and global features. To address this problem, the Transformer from the field of natural language processing (NLP) was introduced to the image segmentation field. Various Transformer-based networks have shown significant performance advantages over mainstream neural networks in different visual tasks, demonstrating the huge potential of Transformers in the field of image segmentation. However, Transformers were originally designed for NLP and ignore the multidimensional nature of images. In the process of operation, they may destroy the 2D structure of the image and cannot effectively capture low-level features. Therefore, we propose a new multi-scale cross-attention method called M-VAN Unet, which is designed based on the Visual Attention Network (VAN) and can effectively learn local and global features. We propose two attention mechanisms, namely MSC-Attention and LKA-Cross-Attention, for capturing low-level features and promoting global information interaction. MSC-Attention is designed for multi-scale channel attention, while LKA-Cross-Attention is a cross-attention mechanism based on the large kernel attention (LKA). Extensive experiments show that our method outperforms current mainstream methods in evaluation metrics such as Dice coefficient and Hausdorff 95 coefficient.

Most prominent topics in wellness tourism research : topic modelling analysis
Mila Zečević, Milica Rančić Demir, 2022, samostojni znanstveni sestavek ali poglavje v monografski publikaciji

Opis: This paper presents a brief overview of the development of the wellness tourism literature. In addition, an analysis and presentation of the topics that appear within this literature field are given. The purpose of this research was to point out the relevant topics that have attracted research efforts over time. In order to detect these topics, we have selected wellness tourism literature articles from Web of Science. Our analysis used topic modelling tools using a machine learning algorithm in Python. The results imply the distinction between two main research topics within wellness tourism literature – wellness and health and medical research. Such differentiation also matches the development of the wellness tourism research field itself.

Amoxicillin doped hyaluronic acid/fucoidan multifunctional coatings for medical grade stainless steel orthopedic implants
Matej Bračič, Sanja Potrč, Matjaž Finšgar, Lidija Gradišnik, Uroš Maver, Hanna Budasheva, Dorota Korte, Mladen Franko, Lidija Fras Zemljič, 2023, izvirni znanstveni članek

Opis: This work investigated the potential of amoxicillin-doped hyaluronic acid/fucoidan multifunctional coatings on medical grade stainless steel as biocompatible, osteointegration enhancing, antimicrobial, and bacterial biofilm inhibiting coatings for orthopedic implants. The coatings were prepared by layer-by-layer spin coating and confirmed by optical contact angle goniometry and infrared spectroscopy. Time-of-flight secondary ion mass spectrometry showed a homogeneous distribution of the individual layers. In contrast, thermal diffusivity, and thermal conductivity measurements by photothermal beam deflection spectrometry showed diffusion of the amoxicillin into the hyaluronic acid and fucoidan layers. In vitro release of amoxicillin showed complete release within one hour, as reflected by the formation of inhibition zones against Staphylococcus aureus and Escherichia coli. Synergistic effects were observed between the hyaluronic acid and amoxicillin in inhibiting S.Aureus biofilm, and between the fucoidan and amoxicillin in improving the antioxidant properties by an ABTS radical scavenging assay. Biocompatibility was determined with human osteoblasts, confirming the potential of such multifunc- tional coatings to enhance the bioactivity of steel-based orthop edic implants.

THE USE OF MEDICAL ACRONYMS AND INITIALISMS IN THE AMERICAN TV SERIES HOUSE MD
Santina Raner, 2017, magistrsko delo

Opis: The present thesis is based on the use of medical acronyms and initialisms in the American TV series House MD as compared to that of medical doctors in Slovenia. The main aim is to determine which medical acronyms are most frequently used in the series and whether they coincide with the acronyms that Slovene doctors use in their work. The second aim is to establish the prevalent language of origin for medical acronyms and initialisms. The theoretical part of the thesis begins with a brief history of acronyms and initialisms, followed by a list of word-formation processes, pronunciation issues and the use of articles with acronyms. The practical part is divided into two sections. The first section covers the transcriptions of the second season of House MD with its twenty-four episodes, where every episode is accompanied by a short data analysis that presents all the medical acronyms featured in the episode. The analysis also includes information as to whether the acronyms are explained in the course of the show, and who uses them (medical or non-medical staff). The second section features four interviews with Slovene doctors from various medical fields (from emergency doctors, physiatrist to veterinarian). The interviews were conducted in Slovene, but the English translations are provided as well for foreign readers. The main focus of the thesis is on determining which medical acronyms are most commonly used, which are loanwords, and the impact of social status on the use of acronyms in speech.

The standards of proof in medical malpractice cases
Nina Cek, 2020, izvirni znanstveni članek

Opis: The article examines the procedural aspect of medical malpractice cases. It focuses on the differences in standards of proof by first explaining the characteristics of the Slovenian legal system and then comparing it with German and English legal systems. The author sheds light on the approach of the EU court on the question of the responsibility of the manufacturer for the product (vaccine) and suggests the direction to use a broader framework for the evaluation of evidence and presumptions. Given the disclosed problems of proving through the help of a medical expert, the article emphasizes the importance of respect for human rights in civil proceedings. Particular emphasis is also placed on no-fault systems and the question is raised of how the introduction of such a system into the Slovenian legal system would affect the perceived problem of proving a medical error and informed consent omission.
