The effect of prophylactic antibiotics on second-stage breast reconstruction: A retrospective analysis.

Background: Implant-based breast reconstruction has a higher infection risk than cosmetic augmentation, leading to routine prophylactic antibiotic use. We previously found extended prophylaxis reduced infections during the first-stage reconstruction with tissue expander/acellular dermal matrix placement. However, the most appropriate antibiotic class and duration of prophylaxis in the second-stage reconstruction remains unclear.

Dysregulated airway epithelial antiviral immunity in Down Syndrome impairs type III IFN response and amplifies airway inflammation during RSV infection.

Trisomy 21 (TS21), also known as Down syndrome (DS), increases pediatric mortality risk from respiratory syncytial virus (RSV) by nine-fold, yet its underlying immunological basis remains unclear. Here, we investigated RSV-induced immunological responses in TS21 airway epithelial cells (AECs), the primary site of respiratory virus entry and host defense. TS21 AECs exhibit hyperactive interferon (IFN) signaling and reduced RSV infectivity, but they also show impaired type-III IFN responses during viral infection.

Adding hydroxyurea to chronic transfusion therapy for sickle cell anemia reduces transfusion burden.

Background: Chronic red blood cell (RBC) transfusion is an established therapy to prevent stroke in patients with sickle cell anemia (SCA). It is unclear if adding daily hydroxyurea treatment to chronic transfusion is beneficial.

Study Design And Methods: We conducted a phase 2 clinical trial (NCT03644953) investigating the addition of dose-escalated hydroxyurea to chronic transfusion for patients with SCA receiving simple chronic transfusion for stroke prevention.

Impact of Viral Lower Respiratory Tract Infection (LRTI) in Early Childhood (0-2 Years) on Lung Growth and Development and Lifelong Trajectories of Pulmonary Health: A National Institutes of Health (NIH) Workshop Summary.

Viral lower respiratory tract infections (LRTI) are ubiquitous in early life. They are disproportionately severe in infants and toddlers (0-2 years), leading to more than 100,000 hospitalizations in the United States per year. The recent relative resilience to severe Coronavirus disease (COVID-19) observed in young children is surprising.
