Photoactive broad-spectrum dressings with antimicrobial and antitumoral properties.

In this work the development of photoactive dressings (PAD) with dual purpose, is presented. These PAD can be used for the topical treatment of persistent infections caused by fungi and bacteria and are also applicable in light antitumor therapy for carcinoma. The synthesized PAD were designed employing conjugated polymer nanoparticles (CPN) doped with platinum porphyrin which serve as polymerization photoinitiators and photosensitizers for the production of reactive oxygen species (ROS).

Seroprevalence study reveals pertussis underreporting in Brazil and calls for adolescent/young adult boosting: mouse model demonstrates immunity restoration.

Background: Pertussis continues to pose a significant threat despite the availability of effective vaccines. The challenge lies in the vulnerability of infants who have not yet completed their vaccination schedule and in adolescents and adults becoming potential disease carriers.

Methods: We evaluated the seroprevalence of pertussis immunity in a cohort of 1,500 healthy Brazilian volunteers.

No impact of HIV coinfection on the mortality in patients with hepatitis C virus infection after sustained virological response.

Background: In patients with hepatitis C virus (HCV) chronic infection and advanced liver disease, the impact of human immunodeficiency virus (HIV) coinfection on the clinical outcome after sustained virological response (SVR) has not been sufficiently clarified. The aim of this study was to compare the mortality after SVR of patients bearing HCV chronic infection and advanced liver fibrosis, with and without HIV-coinfection after a prolonged follow-up.

Methods: This was a prospective multicenter cohort study including individuals with HIV/HCV-coinfection and patients with HCV-monoinfection from Spain, fulfilling: 1) Liver stiffness (LS) ≥9.

Anesthetic Management of a Patient with Renal Cell Carcinoma-Associated Venous Thrombosis and Massive Transfusion.

A 53-year-old male with a history of multiple deep venous thromboses (DVTs) underwent a right open radical nephrectomy with inferior vena cava (IVC) thrombectomy in the context of renal cell carcinoma (RCC)-associated venous thrombosis. Imaging and renal biopsy revealed a diagnosis of RCC with non-occlusive thrombosis of the left renal vein and occlusive thrombosis of the infrarenal IVC. The major risks of concern for the procedure included thrombus embolization from surgical manipulation and massive bleeding.
