Evaluation of Anti-Stroke Drugs
Stroke, also known as transient ischemic attack or cerebrovascular accident, is an acute brain disease. Usually, a sudden rupture of a blood vessel in the brain or a blockage of a blood vessel that prevents blood from flowing to the brain can cause damage to brain tissue, resulting in a stroke. Long-term strokes can lead to brain damage, disability and even death. The brain serves as a ...

CPR Vs. AED Training: What’s The Difference?
Every second counts in any emergency, particularly those involving sudden cardiac events. Training in life-saving procedures becomes pivotal in ensuring that a victim has the best chance of survival. Two terms that often surface in discussions about cardiac emergencies are CPR vs. AED training. While both aim at preserving life during cardiac crises, they serve different functions and involve ...

Influenza A virus replication has a stronger dependency on Raf/MEK/ERK signaling pathway activity than SARS-CoV-2
The recent COVID-19 pandemic again highlighted the urgent need for broad-spectrum antivirals, both for therapeutic use in acute viral infection and for pandemic preparedness in general. The targeting of host cell factors hijacked by viruses during their replication cycle presents one possible strategy for development of broad-spectrum antivirals. By inhibiting the Raf/MEK/ERK signaling pathway, ...

What is heart failure with preserved ejection fraction (HFpEF)?
Overview What is HFpEF? Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome in which patients have signs and symptoms of HF as the result of high left ventricular (LV) filling pressure, despite normal or near-normal LV ejection fraction (EF). Most patients with HFpEF also display normal LV volumes and an abnormal diastolic filling pattern (i.e, diastolic ...

The Future of Quantitative Susceptibility Mapping (QSM) in Clinical Applications
The use of Quantitative Susceptibility Mapping (QSM) is often viewed as incompatible with current standard radiology workflows. Some radiologists or departments may be unaware of its existence or purpose. Despite the skepticism surrounding its viability in a clinical setting, QSM shows great potential in a wide range of clinical applications, particularly for biomarker detection and ...

Ozette’s AI in the battle against Covid - Case study
Summary The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic began in 2019 and rapidly scaled to a global presence of disease known as COVID-19. Despite the relatively fast implementation of testing and vaccination worldwide, the rise of emerging viral variants and breakthrough infections raises concerns that SARS-CoV-2 will continue to pose a global health threat. ...

When IT and OT converge: Paving the way for smarter healthcare
Good decision-making relies on good information. That’s why data collection is so important to businesses of all types. In healthcare, it can literally be a life-and-death concern. Currently, two data-related trends are delivering new levels of optimization in hospitals with the potential to vastly improve operations and safety: The convergence of information technology (IT) systems ...

Evaluation of the Talis One Covid-19 Test System for the Rapid Detection of Sars-Cov-2 and Emerging Variants
Introduction The discovery of a novel coronavirus in December 2019 in the Wuhan province of China and subsequent global spread has caused a pandemic of the scale not seen since the 1918 H1N1 pandemic. The novel coronavirus, classified as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is highly infectious and causes coronavirus disease 2019 (COVID-19), a respiratory and vascular ...

COVID-19 Disease Testing; Utilising Fluorescence During a Pandemic
While the world continues to endure loss and hardship due to the outbreak of COVID-19, caused by a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), researchers are scrambling to provide test kits that are accurate, fast, sensitive, and widely available, especially as symptoms vary broadly and may not appear for days if at all. To this end, several diagnostic methods have been ...

Meet Live, a 4-year-old girl with Rett syndrome who loves action
Live is a tender and cheerful 4-year-old girl. She’s diagnosed with Rett syndrome, but has a more atypical disease course, which means she cannot sit, stand or walk. Live makes good eye contact and has learned to use her eyes and facial expressions to communicate. Live developed as expected until she was around 6 months, but Madeleine, Live’s mother, still felt that something was ...

Temporal quantification of oxygen saturation ranges: an effort to reduce hyperoxia in the neonatal intensive care unit - Case study
Objective: To reduce exposure to hyperoxia and its associated morbidities in preterm neonates. Study design: A multidisciplinary group was established to evaluate oxygen exposure in our neonatal intensive care unit. Infants were assigned target saturation ranges and signal extraction technology implemented to temporally quantify achievement of these ranges. The outcomes bronchopulmonary ...

Accuracy of Pulse Oximeters Intended for Hypoxemic Pediatric Patients - Case study
OBJECTIVES: Prior studies have shown inaccuracies in pulse oximetry readings at saturations less than 85%; however, no large studies have evaluated new sensors marketed for these low saturations. This study's purpose was to evaluate two sensors with claims of improved accuracy in children with saturations less than 85%. DESIGN: Prospective observational study. SETTING: Single institution; ...

The evolution of photoplethysmography (PPG) within smart devices
As a technology, photoplethysmography (PPG) has been explored for almost a century, but it is only in the last few years that it has had a broader application beyond specialised medical settings. That has generally been driven by the evolution of smartphones, smartwatches and even smaller wearable devices such as smart rings. PPG is most commonly used in pulse oximetry in clinical settings ...

Mysterious Deltacron, a Hybrid of Delta and Omicron?
On January 8, 2022, Bloomberg reported that Leondios Kostrikis, a professor of biological sciences at the University of Cyprus, and his team had discovered a new variant of SARS-CoV-2, named "Deltacron" because it has an Omicron-like genetic signature in the Delta genome. Deltacron, according to Kostrikis, mixes genes from Delta and Omicron and may have come from patients who had both Delta and ...

How Reduced Oxygen Delivery Devices are Used in the Military
The defence industry requires advanced technology and solutions for the unique, and often extreme conditions, in which people work. The military conducts scientific and technological research and officer training in high altitude environments with low oxygen levels. Thus, reduced oxygen delivery devices are necessary and widely used by various branches of the military, including the Air Force, ...

Evolution of Anti-SARS-CoV-2 IgG Antibody and IgG Avidity Post Pfizer and Moderna mRNA Vaccinations
Abstract Messenger RNA (mRNA) based vaccines (Pfizer/BioNTech and Moderna) are highly effective at providing immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, there is uncertainty about the duration of immunity, evolution of IgG antibody levels and IgG avidity (an index of antibody-antigen binding strength), and differences in the immune responses between ...

Editorial: Quantitative Susceptibility Mapping in Neurodegeneration
Introduction Magnetic resonance imaging offers a wide variety of contrast mechanisms to study soft tissue in the body. Using the complex data from the SWI scans, it is possible to produce magnetic source images using a novel reconstruction method that takes the phase data and reconstructs what is referred to as a quantitative susceptibility map (QSM). The phase images represent local frequency ...
