Biofouling in membrane filtration systems poses significant operational challenges, leading to decreased permeate flux. The aim of this work was to study the anti-biofilm properties of new nanofiltration membranes produced via layer-by-layer, LBL, assembly by coating a polyvinylidene fluoride (PVDF) support with a polyethylenimine (PEI) and poly(acrylic acid)/graphene oxide (PAA-GO) mixture. The membranes were characterized according to contact angle, scanning electron microscopy (SEM), atomic force microscopy and their Z-potential.

Secondary objectives involved identifying the factors contributing to developmental disparities across diverse racial and ethnic groups.
Study Design: Electronic health records from a Southern California high-risk infant follow-up clinic were analyzed for 440 infants from 2014 through 2023 who had either had neonatal intensive care unit stays, prematurity, very low birthweight, or developmental delay risk.
Background: Coronary artery pseudoaneurysm (PSA) is a rare occurrence linked to percutaneous coronary interventions (PCIs), infection, or chest trauma, lacking established management guidelines due to its low incidence.
Case Summary: A 78-year-old male with a medical history of triple vessel disease, post coronary artery bypass grafting, heart failure, and chronic obstructive pulmonary disease, presented with intractable left-sided chest pain following a mechanical fall. The initial workup was positive for mildly elevated high-sensitivity troponin and brain natriuretic peptide raising suspicion for a pulmonary embolism; but chest computed tomography angiography revealed an enlarging pericardial haematoma.
