In a 429-person sleep intervention study, proposed brain-scan measures of waste clearance responded differently to restricted sleep and prolonged wakefulness.In a 429-person sleep intervention study, proposed brain-scan measures of waste clearance responded differently to restricted sleep and prolonged wakefulness.
Preprint: non-randomised trial in 429 people exposed to short-term sleep loss, against habitual sleepMechanisms
Limit: MRI indices were indirect markers, not direct measurements of brain waste clearance
A genome-sequencing study resolved both inherited copies of the naked mole-rat genome, using gene-activity data from 23 tissues to identify its genes.A genome-sequencing study resolved both inherited copies of the naked mole-rat genome, using gene-activity data from 23 tissues to identify its genes.
In laboratory experiments, reducing the protein weakened two drugs’ cell-killing effects without changing the usual signs of senescence, a state in which cells stop…In laboratory experiments, reducing the protein weakened two drugs’ cell-killing effects without changing the usual signs of senescence, a state in which cells stop dividing.
In frail patients, dapagliflozin was linked to lower relative risk of death or worsening heart failure versus controls at one year (hazard ratio 0.53).In frail patients, dapagliflozin was linked to lower relative risk of death or worsening heart failure versus controls at one year (hazard ratio 0.53).
Study of 1,222 patients undergoing transcatheter aortic valve implantation, against frail controlsDapagliflozin
Limit: Frailty subgroups were analysed after the fact, so the apparent extra benefit needs confirmation
