Age-dependent and sex-dependent differences in mortality from influenza-associated cardiovascular diseases among older adults in Shanghai, China: a population-based study
Conclusions Excess mortality rates for CVDs associated with influenza increased with age in older adults. The risk for influenza-associated IHD mortality was significantly higher in older women than men. Our findings will help implement targeted health strategies, including the promotion of influenza vaccination and early therapeutic intervention for the older population with CVD, to curb the influenza burden effectively.

Ictogenesis of viral pneumonia: A comparison between SARS-CoV-2 and H1N1/H3N2
Epilepsy Behav. 2021 Dec 10;126:108470. doi: 10.1016/j.yebeh.2021.108470. Online ahead of print.ABSTRACTSeveral studies reported acute symptomatic seizures as a possible neurological complication of COVID-19 pneumonia. Apart from metabolic imbalances, hypoxia, and fever, other ictogenic mechanisms are likely related to an immune-mediated damage. The same mechanisms are shared by other respiratory viruses. Since neurotropic properties of SARS-CoV-2 have been questioned, we investigated whether SARS-CoV-2 has a similar ictogenic potential to other respiratory non-neurotropic viruses. We conducted a retrospective study identi...

Get the flu vaccine, reduce your risk of death
Last year was a lousy year for the flu vaccine. Hospitalizations for flu hit a nine-year high, and the vaccine prevented flu in only 23% of all recipients, compared with 50% to 60% of recipients in prior years. Why does the flu vaccine work well in some winters and not others? The flu vaccine primes the immune system to attack two proteins on the surface of the influenza A virus, hemagglutinin (H) and neuraminidase (N). Different flu strains have different combinations of these proteins — for example, the strains targeted by recent flu vaccines are H3N2 and H1N1. Unfortunately, the influenza virus is microbiology’s ans...
