Immediate bisphosphonate use with endocrine therapy reduced recurrence and increased survival in postmenopausal early breast cancer

The addition of zoledronic acid to adjuvant endocrine therapy increased bone mineral density and reduced disease recurrence among postmenopausal women with early hormone receptor-positive breast cancer. Immediate zoledronic acid use also improved survival outcomes, particularly in women who were truly menopausal at diagnosis.

NEJM publishes study showing LigoCyte's norovirus vaccine demonstrates protection against illness

A Phase I/II study demonstrated the experimental norovirus VLP vaccine significantly reduces the incidence of gastroenteritis due to norovirus, with a 47% reduction compared to placebo. The vaccine also increased antibody titers and functional responses in subjects, indicating increased protection against illness.

Behavior of people faced with health-care choices is not influenced by 'framing effect,' study finds

A recent study by researchers at the University at Buffalo found that framing effects have a minimal influence on consumer behavior when making health decisions. This contradicts the widely held medical premise that framing affects health behaviors, suggesting language and other factors play a more significant role.
