What words in online reviews tell us about hospital visits

Online reviews can provide insight into what influences whether patients have a “good” or “bad” health care experience, a Penn Medicine analysis shows.

Significant racial discordance between nurses and patients in Black-serving hospitals

Significant racial discordance between nurses and patients in Black-serving hospitals

A new Penn Nursing Center for Health Outcomes and Policy Research study reveals a significant underrepresentation of Black nurses compared to the Black patient populations they serve, particularly in hospitals that care for a higher proportion of Black patients. The study, led Eileen T. Lake, the Edith Clemmer Steinbright Professor in Gerontology, Professor of Nursing and Sociology, and CHOPR associate cirector, is set to be published in Nursing Research.

Key to improving survival of transplanted retinal cells

New device could streamline vision-saving therapies

New device could streamline vision-saving therapies

A new study by a team of vision scientists from the Division of Experimental Retinal Therapies at Penn Vet, led by William A. Beltran, have worked to demonstrate that a novel surgical tool used previously in gene and cell therapy clinical trials can place therapies directly beneath the retina using a minimally invasive approach.

Stem cell secretions show promise in boosting oral tissue regeneration

Stem cell secretions show promise in boosting oral tissue regeneration

A preclinical study from researchers at Penn Dental Medicine shows that the molecular secretions of stem cells taken from human gum tissue could someday be used to speed the healing and regeneration of damaged tissues in the mouth.

Early challenges to the immune system disrupt oral health

Modupe O. Coker from the School of Dental Medicine and a collaborative team of researchers identified changes over time in the oral microbiome of children living with HIV, offering insights into how early immune challenges shape not only oral health but also systemic health.

Beneath the surface: Diving into water’s hidden carbon-cleaning capabilities
3D rendering of water molecules on a copper surface.

Water molecules become increasingly disordered at the surface of a catalyst. Researchers found that this disordered interfacial water, shown transitioning from structured (left) to disorganized (right), plays a key role in speeding up the conversion of carbon monoxide into ethylene, a valuable fuel and chemical building block.

Beneath the surface: Diving into water’s hidden carbon-cleaning capabilities

Penn materials scientist Shoji Hall and colleagues have found that manipulating the surface of water can allow scientists to sustainably convert greenhouse gases like carbon dioxide and carbon monoxide to higher energy fuel sources like ethylene.
