Clinical Effectiveness of SARS-CoV-2 Vaccination in Renal Transplant Recipients. Antibody Levels Impact in Pneumonia and Death.

Background: Few studies have described the clinical impact of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in renal transplant recipients (RTRs) in the context of omicron variant and the third vaccine dose. Antibody titer has been tried to relate to the prediction of outcomes related to SARS-CoV-2, but it results controversially in these populations.

Methods: All patients with positive SARS-CoV-2 polymerase chain reaction followed at a RTRs reference center from March 15, 2020, to March 15, 2022, were considered for analysis.

Impact of microplastics and ocean acidification on critical stages of sea urchin (Paracentrotus lividus) early development.

One of the major consequences of increasing atmospheric CO is a phenomenon known as ocean acidification. This alteration of water chemistry can modulate the impact on marine organisms of other stressors also present in the environment, such as microplastics (MP). The objective of this work was to determine the combined impact of microplastic pollution and ocean acidification on the early development of Paracentrotus lividus.

Successful Conservative Treatment of a Large Infected Saphenous Graft Aneurysm: Usefulness of PET/CT.

We report a case of a 75-year-old man with a medical history of coronary artery bypass graft surgery and a recent graft angioplasty, who presented to our emergency department with fever. An 18F-fluorodeoxyglucose positron emission tomography demonstrated a saphenous graft infected aneurysm, which was successfully treated conservatively with antibiotic therapy. ().
