An age-of-infection model with both symptomatic and asymptomatic infections [PDF]

arXiv, 2021
We formulate a general age-of-infection epidemic model with two pathways: the symptomatic infections and the asymptomatic infections. We then calculate the basic reproduction number $\mathcal{R}_0$ and establish the final size relation. It is shown that the ratio of accumulated counts of symptomatic patients and asymptomatic patients is determined by ...

On the Universality of Jordan Centers for Estimating Infection Sources in Tree Networks [PDF]

, 2014
Finding the infection sources in a network when we only know the network topology and infected nodes, but not the rates of infection, is a challenging combinatorial problem, and it is even more difficult in practice where the underlying infection spreading model is usually unknown a priori. In this paper, we are interested in finding a source estimator

Antibiotic prophylaxis with amoxicillin to prevent infective endocarditis in periodontitis patients reconsidered: a narrative review

Swiss Medical Weekly, 2021
OBJECTIVES: To discuss first, the adequacy of the antibiotic prophylaxis regimen currently recommended for the prevention of infective endocarditis in periodontitis patients, and second, preventive measures to decrease the rate of bacteraemia after ...

Unlocking the Gates: A Novel Diagnostic Molecule for Quantifying Efflux Levels in Gram‐Positive Bacteria

Advanced Healthcare Materials, EarlyView.
Efflux‐mediated resistance compromises antibiotic efficacy, yet rapid detection remains elusive. This study presents a novel phenazinium‐based diagnostic molecule for quantifying bacterial efflux levels in Gram‐positive pathogens. The optimized compound enables precise, real‐time efflux assessment using fluorescence and colorimetric techniques ...

Advancements in left ventricular assist devices to prevent pump thrombosis and blood coagulopathy

Journal of Anatomy, Volume 242, Issue 1, Page 29-49, January 2023., 2023
Left ventricular assist device (LVAD)‐related blood coagulopathy: Pump thrombosis is one of the most severe adverse events caused by LVADs. The contact of blood with artificial materials of LVAD pumps and cannulas triggers the coagulation cascade. Abstract Mechanical circulatory support (MCS) devices, such as left ventricular assist devices (LVADs) are

A Case Report of Successful Conservative Treatment for Infective Endocarditis Caused by Gemella sanguinis

Case Reports in Infectious Diseases, 2019
Infective endocarditis is defined as an infection of a native or prosthetic heart valve, the endocardial surface of the heart, or an indwelling cardiac device.

Spatially dense stochastic epidemic models with infection-age dependent infectivity [PDF]

arXiv, 2023
We study an individual-based stochastic spatial epidemic model where the number of locations and the number of individuals at each location both grow to infinity. Each individual is associated with a random infection-age dependent infectivity function. Individuals are infected through interactions across the locations with heterogeneous effects.

Metal–Organic Framework‐Based Antimicrobial Touch Surfaces to Prevent Cross‐Contamination

Advanced Materials, EarlyView.
A MOF‐based antimicrobial door handle cover is developed. It completely inhibits the cross‐contamination of Gram‐positive bacterial species (Staphylococcus aureus, and Enterococcus faecalis), Gram‐negative bacterial species (Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii), and fungi (Candida albicans). Abstract Infection diseases

A European update on transcatheter aortic valve implantation (TAVI) in the COVID era

Journal of Anatomy, Volume 242, Issue 1, Page 50-63, January 2023., 2023
A timely review of key Transcatheter Aortic Valve Implantation (TAVI) device trials delineated by surgical risk. Abstract Minimally invasive approaches for aortic valve replacement are now at the forefront of pathological aortic valve treatment. New trials show comparability of these devices to existing therapies, not only in high‐risk surgical cohorts

Patients with infective endocarditis undergoing cardiac surgery have distinct ROTEM profiles and more bleeding complications compared to patients without infective endocarditis

PLoS ONE, 2023
Background The coagulation system is crucial in the pathogenesis of infective endocarditis and undergoes significant changes during course of the disease. However, little is known about the implications of those changes in the perioperative period.
