Pulse waves measured at the wrist uncover often-missed artery changes in menopausal women

Measuring a menopausal woman's pulse wave at her wrist can detect circulatory system changes that aren't evident with blood pressure readings. Menopause's effect on these radial pulse wave harmonics can help explain why women in menopause are at heightened cardiovascular disease risk.

E. coli superbug strains can persist in healthy women's guts

A study of over 1,000 healthy women with no urinary tract infection symptoms showed nearly 9% carried multi-drug resistant Escherichia coli strains in their guts. Additional findings highlight likely reasons behind the pandemic of resistant E. coli strains. They show the value of checking a patients' carrier-status to predict resistant infections, and the need to re-think the clinical significance of bacteria in the urine without symptoms, because pandemic strains can be highly pathogenic to the urinary system and treatment resistant.

Killing the seeds of cancer: A new finding shows potential in destroying cancer stem cells

When doctors remove a tumor surgically or use targeted therapies, the cancer may appear to be gone. However, evidence suggests a tiny subpopulation of adaptable cancer cells can remain and circulate through the body to seed new metastasis in far-off locations. A collaborative research project has identified an entirely new class of molecules that shows promise in rooting out and killing those cancer stem cells.
