Understanding the impact of racism on surgical outcomes in settler nation-states USA and Canada: a protocol for a systematic review and meta-analysis.

Introduction: To improve surgical quality and safety, health systems must prioritise equitable care for surgical patients. Racialised patients experience worse postoperative outcomes when compared with non-racialised surgical patients in settler colonial nation-states. Identifying preventable adverse outcomes for equity-deserving patient populations is an important starting point to begin to address these gaps in care.

Associations between degree of food processing and all-cause and cause-specific mortality: a multicentre prospective cohort analysis in 9 European countries.

Background: Ultra-processed food (UPF) consumption has been linked with higher risk of mortality. This multi-centre study investigated associations between food intake by degree of processing, using the Nova classification, and all-cause and cause-specific mortality.

Methods: This study analyzed data from the European Prospective Investigation into Cancer and Nutrition.

A 3D Model of the Human Lung Airway for Evaluating Permeability of Inhaled Drugs.

Current in vitro cell-based methods, relying on single cell types, have structural and functional limitations in determining lung drug permeability, which is a contributing factor affecting both local and systemic drug levels. To address this issue, we investigated a 3D human lung airway model generated using a cell culture insert, wherein primary human lung epithelial and endothelial cells were cocultured at an air-liquid interface (ALI). To ensure that the cell culture mimics the physiological and functional characteristics of airway tissue, the model was characterized by evaluating several parameters such as cellular confluency, ciliation, tight junctions, mucus-layer formation, transepithelial electrical resistance, and barrier function through assaying fluorescein isothiocyanate-dextran permeability.

From skin to heart: The rare journey of pleomorphic dermal sarcoma metastasis.

Cardiac tumours can be classified as neoplastic or non-neoplastic, with secondary tumours being significantly more common than primary ones. Among secondary tumours, melanoma has the highest propensity for cardiac involvement. Pleomorphic dermal sarcoma (PDS) is a rare skin neoplasm, with an estimated metastatic risk of 10% to 20%.
