Myocarditis is a general group of bodily functions that lead to heart muscle inflammation. Some patients experience a marked localized inflammation, while others experience a more diffuse inflammation, affecting large portions of the heart. In addition, the precise role of the pathogenic agent that causes inflammation as well as the interaction with the immune system in the disease progression is also under discussion. In this situation, computational techniques can help specialists to understand better the links between pathogens and the immune system, as well as determine why certain patients experience diffuse myocarditis. In acute infectious myocarditis, this paper expands a recently developed method to investigate myocardial oedema formation. The poroelastic model was shown to demonstrate local and diffuse myocarditis dynamics in simplified and complicated geometrical domains.

For the production of vaccines and research of pathogenicity, In-vivo models of Actinobacillus pleuropneumoniae infection in pigs is required. diffuse visible dermal oedema and inflammation was induced by serovar 1 and serovar 10 Apps. ApxI-producing strains of App caused more inflammation than ApxII- and ApxIII-producing strains. Induction of skin lesions by injection of App or Apx toxins was not sufficiently reproducible or discrete for a robust experimental framework that could be used to evaluate novel interventions.

Patients with hypoxaemic respiratory failure mainly due to pneumonia, and it has been non-inferior to non-invasive positive pressure ventilation in patients with hypoxaemic respiratory failure mainly due to pneumonia. We therefore planned this research to investigate the effects of HFNC compared to NIPPV for emergency patients with ACPE.

While neuropathological examinations in patients who died from COVID-19 revealed inflammation in cerebral white matter, cerebral MRI often struggles to detect anomalies even in the absence of neurological signs. In this multicentric prospective research, 20 COVID-19 inpatients with neurological signs and cognitive impairments as a result of the Montreal Cognitive Assessment tested for DMI in the subacute stage of the disease. A comparison of whole-brain white matter DMI parameters with a matched healthy control group revealed a significant increase in volume from the intra- and extra-axonal space to the free water fraction. A network of most affected white matter fibres linking numerous cortical regions in all cerebral lobes has been found by streamline-wise comparisons of COVID-19 patients and controls, which have expanded to a network of most affected white matter fibres linking widespread cortical regions in both cerebral lobes. In summary, DMI in subacute COVID-19 patients demonstrated significant volume shifts compatible with vaping oedema, impacting various supratentorial white matter tracts.

Cardiobacterium hominis, a member of the HACEK group of bacteria responsible for infectious endocarditis, is most prevalent in patients with damaged or prosthetic valves. In the absence of fever, the diagnosis of infectious endocarditis is difficult because other signs of inflammatory syndrome are non-specific and biological markers of inflammation are non-existent. This is the first case of C. hominis infectious endocarditis with a clinical sign of acute pulmonary oedema in the literature. We present here an apyretic pulmonary oedema revealing C. hominis endocarditis and a study of the literature on apyretic infective endocarditis related to C. hominis.
