Researchers from Drexel University’s College of Nursing and Health Professions worked with people who have obesity to redesign what an “ideal” primary care visit could look like and validate their ideal visit concept among a sample of adults with obesity.

Salmonella Dublin, a type of bacteria that primarily infects cattle but some strains also can adapt to infect humans, is increasingly becoming resistant to antibiotics, making it a growing public health threat, according to the U.S. Centers for Disease Control and Prevention. Researchers at Penn State investigated how strains of the pathogen — which can cause severe illness and death in cattle and blood infections and hospitalization in humans are evolving and spreading across humans, cattle and the environment in the United States.

Carotid endarterectomy (CEA) is a surgical procedure to remove plaque buildup in the carotid artery, which supplies blood to the brain. Although its efficacy is known, the effect of CEA on the blood-brain barrier (BBB) properties has not been examined. Now, Chinese scientists have examined CEA-induced changes in the hemodynamic and BBB properties in patients with severe carotid artery stenosis using computed tomography perfusion scanning, demonstrating improved blood flow and enhanced BBB permeability reversal.

Sustained hypoxia affects orthodontic tooth movement (OTM) by altering osteoclast and osteoblast differentiation, report researchers from Institute of Science Tokyo, Japan. Hypoxic conditions resulted in reduced alveolar bone levels after OTM and lower expression of runt-related transcription factor 2 and vascular endothelial growth factor. These findings, observed in a rat model, provide critical insights into the bone remodeling process in OTM under hypoxia.
