Epidural abscess is a rare complication of neuraxial techniques, which, when left unnoticed, can lead to significant neurological deficits and poor outcomes. Identification of patients at high risk and the conduct of a strict aseptic technique are some of the measures that play an important role in epidural abscess prevention. Prompt recognition and treatment of epidural abscesses are essential.

Extended-spectrum β-lactamase (ESBL)-producing Escherichia coli poses a significant threat to public health due to its ability to confer resistance to broad-spectrum antimicrobials, especially third-generation cephalosporins. Herein, we report gut colonization by international clones of CTX-M-8-producing E. coli in scorpion mud turtles (Kinosternon scorpioides) from a captive breeding program in the Brazilian Amazon.

Emerging cellulose nanomaterials (CNMs) may have commercial impacts in multiple sectors, being their application particularly explored in the food sector. Thus, their potential adverse effects in the gastrointestinal tract should be evaluated before marketing. This work aimed to assess the safety of two CNMs (CNF-TEMPO and CMF-ENZ) through the investigation of their cytotoxicity, genotoxicity (comet and micronucleus assays), and capacity to induce reactive oxygen species in human intestinal cells, and their mutagenic effect using the Hprt gene mutation assay.

Compound (4-(3,5-di-tert-butyl-4-hydroxybenzylamine)benzenesulfonamide) (LQFM275) was designed and synthesized from darbufelone and sulfanilamide as a new multi-target for the treatment of inflammatory diseases. LQFM275 showed a great range of safe cytotoxicity profile (100-400 μM) evaluated by MTT assay, preventing damage induced by lipopolysaccharide (LPS) in EA.hy926 cell line.

Biomimetic nanocarriers, engineered to mimic the characteristics of native cells, offer a revolutionary approach in the treatment of various complex human diseases. This strategy enhances drug delivery by leveraging the innate properties of cellular components, thereby improving biocompatibility and targeting specificity. Biomimetic nanocarriers demonstrate significant advancements in drug delivery systems against cancer therapy, Alzheimer's disease, autoimmune diseases, and viral infections such as COVID-19.
