A new study reveals that patients hospitalized with COVID-19 had a higher in-hospital mortality and persisted at 30 days, 90 days, and 180 days after discharge. The risk of death was nearly twice that observed in those who were discharged alive from an influenza-related hospital admission.
Researchers propose a novel theory of aging that suggests cell competition is a key factor in the process. The selective destruction theory (SDT) proposes a mechanism of aging that is independent of accumulating damage and consistent with epigenetic rejuvenation.
A large head-to-head comparison study of the Moderna and Pfizer-BioNTech vaccines found that the Moderna vaccine was associated with a slightly lower risk of adverse events for older adults. The study also showed that the Moderna vaccine was linked to a 4% lower risk of pulmonary embolism and a 15% lower risk of diagnosed COVID-19.
Researchers found that adults who experienced violence, financial stress, or separation from parents as children were more likely to experience physical and cognitive impairments. Adverse childhood experiences can have lifelong consequences, including difficulty walking, carrying out daily activities, and problems with memory.
A new study published in JAMA Ophthalmology found that vision problems are more common in older adults with dementia. The study of nearly 3,000 older adults showed that even mild vision issues were associated with a higher risk of dementia.
The American College of Physicians recommends starting colorectal cancer screening at age 50 for asymptomatic adults with average risk. The guideline aims to balance benefits and harms of screening in this population. Screening in younger adults may not offer significant net benefit due to lower incidence rates.
A recent study by Tufts University researchers found that myo-inositol in human breast milk increases synaptic connections between neurons, indicating stronger brain connectivity. This finding could lead to improved infant formulas and better brain health outcomes for adults with certain psychiatric conditions.

Researchers investigated hepatic hydrogen sulfide production in a mouse model of Hutchinson-Gilford Progeria Syndrome (HGPS) and found reduced H2S levels in RC-fed mice, with partial rescue on high-fat diet. This study suggests that accelerated aging in HGPS may be partially explained by reduced hepatic H2S levels.
A new study suggests that reduced brain gray matter volume may mediate the association between glycemia and depression. Researchers observed a significant correlation between elevated glycosylated hemoglobin levels, reduced GMV, and depression in a large cohort of participants.
A large US study of over half a million adults found that BMI was not significantly linked to increased all-cause mortality in most cases. The study suggests that further research is needed to fully understand the relationship between BMI and mortality risk, particularly among younger adults.
