The complement system is an essential component of the innate immune system. Its excessive activation during COVID-19 contributes to cytokine storm, disease-specific endothelial inflammation (endotheliitis) and thrombosis that comes with the disease. Targeted therapies of complement inhibition in COVID-19, in particular blocking the C5a-C5aR1 axis have to be taken into account in the establishment of potential biomarkers and development of therapeutic strategies in the most severe forms of the disease.

Background: Operative management of chronic Achilles tendinopathy with large defects can be surgically challenging. Concerns exist regarding transosseous transfer of the flexor hallucis longus (FHL) tendon because of the shortened lever arm of flexion and weakening of the big toe. The aim of this study was to demonstrate the 2-year outcome of transosseous FHL transfer for the treatment of large Achilles tendon defects.

Cancer immunotherapy, particularly immune checkpoint inhibitors, has positively impacted oncological treatments. Despite its effectiveness, immunotherapy is associated with immune-related adverse events (irAEs) that can affect any organ, including the liver. Hepatotoxicity primarily manifests as immune-related hepatitis and, less frequently, cholangitis.

: There is a constant need to improve the prediction of adverse neurodevelopmental outcomes in growth-restricted neonates who were born prematurely. The aim of this retrospective study was to evaluate the predictive performance of a three-layered neural network for the prediction of adverse neurodevelopmental outcomes determined at two years of age by the Bayley Scales of Infant and Toddler Development, 3rd edition (Bayley-III) scale in prematurely born infants by affected by intrauterine growth restriction (IUGR). : This observational retrospective study included premature newborns with or without IUGR admitted to a tertiary neonatal intensive care unit from Romania, between January 2018 and December 2022.

Fixed drug eruption (FDE) is a type of drug-induced skin inflammation characterized by the recurrence of lesions in the same region following repeated exposure to the causative drug. FDE typically presents as localized spots or plaques without systemic symptoms; however, it can manifest in other forms, such as blisters and papules. In FDE, effector memory CD8-positive T cells that remain dormant in the basal layer after a previous inflammation are reactivated upon re-exposure to the causative drug, leading to the development of erythema at the same sites.
