Pesticide exposure linked to stillbirth risk in new study

A new study found that living near areas where pesticides were used during the first trimester of pregnancy or pre-conception increases the risk of stillbirths. Researchers linked pesticide use records to state birth certificate data and found specific chemicals, such as organophosphates and pyrethroids, to be associated with increased...

Poor sleep linked to migraine attacks in new UArizona Health Sciences study

A new study by UArizona Health Sciences researchers found that sleep disturbances increase the vulnerability to migraine attacks. Improving sleep health may decrease the likelihood of migraine attacks in people with migraine. The study used preclinical mouse models and found no link between migraine-like pain and disrupted sleep.

NIA grant supports training of next generation of translational scientists for Alzheimer’s disease therapeutic development

Researchers at the University of Arizona Health Sciences will train the next generation of translational scientists in Alzheimer's disease research through a $1.4 million grant. The program aims to develop highly trained, cross-disciplinary researchers to address the complex challenges of this devastating neurodegenerative disorder.

College of Medicine – Tucson researchers tackle immune rejection of biomedical implants

A team of researchers identified a protein called RAC2 that appears to drive the foreign body response, which causes the body to reject biomedical implants. Suppressing production of this protein could reduce the risk of implant rejection and improve the design and safety of implants.

UArizona College of Nursing receives $2.6M HRSA grant to support Doctor of Nursing Practice students' clinical placements

The University of Arizona College of Nursing will deploy immersive managed practice adaptable clinical training starting in the spring semester of 2024, supporting 19 students per year with $25,000 each. The grant also helps establish a longitudinal clinical placement model and provides financial support for community partners.

People of color receive less suicide prevention care at emergency departments

A recent study found that people of color with alcohol use disorder receive less suicide prevention care at emergency departments, despite similar levels of elevated suicide ideation. The research highlights the need for healthcare providers to address disparities in behavioral health care and provide culturally sensitive treatment.
