This investigation sought to quantify the temporal association between population increases in seasonal influenza infections and mortality due to cardiovascular causes as well as to determine if influenza incidence indicators are predictive or cardiovascular mortality during influenza season. The researchers found that emergency department visits for adults over age 65 for influenza-like illness were associated with and predictive of cardiovascular disease mortality.
This Advisory Committee Statement includes findings from a large randomized controlled trail of people 65 and over who received a high dose vaccine compared to the standard dose vaccine. Those on the higher dose had a relatively higher serologic response and reduced influenza illness compared to those who had the standard dose but also had a higher rate of post-injection local adverse events.
The authors of this cross-sectional observational study attempted to evaluate the influence on statin therapy on the immune response to vaccination in elderly individuals. Their findings suggest that chronic synthetic statin therapy may have an immunosuppressive effect on the vaccine immune response.
The authors evaluated the association between ambient temperature and cerebral vascular function among 432 participants ≥65 years old from the MOBILIZE Boston Study with data on cerebrovascular blood flow, cerebrovascular resistance, and cerebrovascular reactivity in the middle cerebral artery.
The authors measured the lag effects of temperature, relative humidity, atmospheric pressure and fine particulate matter on hospitalizations and deaths for heart failure in elderly diagnosed with this disease over a ten year period in Quebec. They found a drop of 10°C in the average temperature over 7 days was associated with increased risk to be hospitalized or death for heart failure in around 7% of the elderly diagnosed with this disease.
This population-based case-control study in Hamilton, Ontario concluded that in older adults, exposure to ambient nitrogen dioxide and fine particulate matter (PM2,5) were associated with hospitalization for community-acquired pneumonia.
This article discusses the impact of light on the human circadian system, seasonality of human cognitive brain function, immunity and physiology. The authors touch upon the use of light therapy for geriatric depression and the importance of learning more about the circadian system in aging to improve cognitive function, mood, and sleep in relation to dementia.
