BREAST+: An augmented reality interface that speeds up perforator marking for DIEAP flap reconstruction surgery.

Deep inferior epigastric artery perforator flap reconstruction is a common technique for breast reconstruction surgery in cancer patients. Preoperative planning typically depends on radiological reports and 2D images to help surgeons locate abdominal perforator vessels before surgery. Here, BREAST+, an augmented reality interface for the HoloLens 2, designed to facilitate accurate marking of perforator locations on the patients' skin and to seamlessly access relevant clinical data in the operating room is proposed.

Evaluation of the cyto- and genotoxicity of two types of cellulose nanomaterials using human intestinal cells and in vitro digestion simulation.

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.

Setting: Western Brazilian Amazon, Cruzeiro do Sul, Acre, Brazil.

Multimodality imaging of pediatric ascariasis.

Ascariasis is a prevalent intestinal helminthic infection caused by Ascaris lumbricoides, commonly known as roundworm. While the disease may remain asymptomatic when the parasites are confined to the intestinal lumen of the small bowel, symptoms and complications can arise when the helminths invade the biliary tree or pancreatic ducts. In cases of severe infection, a mass of roundworms can lead to intestinal complications, such as bowel obstruction.
