Nowadays sensors and especially biosensors play an important role in medical diagnosis and detection of food and environment contaminations. Biosensors’ facilities have been improved significantly by using technologies such as surface plasmon resonance, microfluidics, laser, and electrochemistry. These technologies are now available on chips in micro- and nano-scale and are capable of measuring the quantity of more than one analyte at once. One branch of these sensors is the holographic (bio)sensor. Reflection holographic sensors, which are optical devices fabricated based on Bragg’s law, can diffract light with specific wavelength as they absorb or release special ions or molecule depending on their polymer structure...

The incidence of hospital-acquired infections is to a large extent due to device-associated infections. Bacterial attachment and biofilm formation on surfaces of medical devices often act as seeding points of infection. To prevent such infections, coatings based on silver nanoparticles (AgNPs) are often applied, however with varying clinical success. Here, the traditional AgNP-based antibacterial technology is reimagined, now forming the base for an electroenhanced antimicrobial coating. To integrate AgNPs in an electrically conducting polymer layer, a simple, yet effective chemical strategy based on poly(hydroxymethyl 3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT-MeOH:PSS) and (3-aminopropyl)triethoxysilane is designed...

Induced pluripotent stem cells (iPSCs) technology is a method for generating pluripotent stem cells in vitro from fully differentiated cells such as fibroblast cells. The potential applications of iPSC technology in cell therapy and disease modeling could influence current medical practices. Despite current advances in iPSC technology, many patient-derived reprogrammed cells are not suitable for clinical trial because most protocols rely on virus-based techniques, which pose the risk of integration of the viral genome into the chromosomes...

Clinical alarm systems have received significant attention in recent years following warnings from hospital accrediting and health care technology organizations regarding patient harm caused by unsafe practices. Alarm desensitization or fatigue from frequent, false, or unnecessary alarms, has led to serious events and even patient deaths. Other concerns include settings inappropriate to patient population or condition, inadequate staff training, and improper use or disabling. Research on human factors in alarm response and of functionality of medical devices will help clinicians develop appropriate policies, practices, and device settings for clinical alarms in neonatal intensive care units...

Complex biochemical mechanisms are being involved in oleaginous microorganisms during storage lipid and polysaccharide metabolism. Detailed biochemical analyses and monitoring of key enzymes involved in carbon metabolism were performed in Yarrowia lipolytica and Umbelopsis isabellina, which are often used as model oleaginous microorganisms. It was found that during the early oleaginous phase, the carbon source (glucose) was channeled to lipid accumulation, but also to polysaccharide biosynthesis. However, during transition from the early to the late oleaginous phase, glucose was exclusively converted to lipids, while in U...

INTRODUCTION: Osteoporosis prevention is heavily reliant on education programs, which are most effective when tailored to their intended audience. Most osteoporosis prevention education is designed for older adults, making application of these programs to younger adults difficult. Designing programs for young adults requires understanding the information-seeking practices of young adults, so that knowledge about osteoporosis can be effectively translated. METHODS: Individual interviews were conducted with 60 men and women-multiethnic, Canadian young adults-to explore both the sources and types of information they search for when seeking information on nutrition or bone health...

Despite the rapid growth of three-dimensional (3D) printing applications in medicine, the accuracy and reproducibility of 3D printed medical models have not been thoroughly investigated. Although current technologies enable 3D models to be created with accuracy within the limits of clinical imaging spatial resolutions, this is not always achieved in practice. Inaccuracies are due to errors that occur during the imaging, segmentation, postprocessing, and 3D printing steps. Radiologists' understanding of the factors that influence 3D printed model accuracy and the metrics used to measure this accuracy is key in directing appropriate practices and establishing reference standards and validation procedures...

Inflammatory bowel disease (IBD) is a chronic and relapsing disorder with significant medical, social and financial impacts. IBD patients require continuous follow-up, and healthcare resource use in this context increases over time. In the last decade, telemedicine has influenced the treatment of chronic diseases like IBD via the application of information and communication technologies to provide healthcare services remotely. Telemedicine and its various applications (telemanagement, teleconsulting and tele-education) enable closer follow-up and provide education resources that promote patient empowerment, encouraging treatment optimisation over the entire course of the disease...

By 2030, road traffic accidents are projected to be the fifth leading cause of death worldwide, with 90% of these deaths occurring in low- and middle-income countries (LMICs). While high-quality, prehospital trauma care is crucial to reduce the number of trauma-related deaths, effective Emergency Medical Systems (EMS) are limited or absent in many LMICs. Although lay providers have long been recognized as the front lines of informal trauma care in countries without formal EMS, few efforts have been made to capitalize on these networks...
