In the United States, annual influenza vaccination is recommended for all persons aged ≥6 months. Using data from four vaccine effectiveness (VE) networks during the 2023-24 influenza season, interim influenza VE was estimated among patients aged ≥6 months with acute respiratory illness-associated medical encounters using a test-negative case-control study design. Among children and adolescents aged 6 months-17 years, VE against influenza-associated outpatient visits ranged from 59% to 67% and against influenza-associated hospitalization ranged from 52% to 61%.

Therapy duration of 1 year or less may not be beneficial (SOR: C, secondary analyses in meta-analyses).

  • * A trial with 30 participants compared Aquamin against calcium alone and a placebo over 90 days, examining colonic biopsies for specific protein expressions before and after the treatment.
  • * Results showed Aquamin reduced Ki67 (a marker for cell proliferation) and slightly increased CK20 (a differentiation marker), with broader protein expression changes compared to calcium alone, suggesting potential benefits for colonic health.

The duration of the trip would necessitate a much longer exposure to deep space radiation than any human has ever been exposed to in the past. Concern regarding cancer risk has thus far stalled the progress of deep space exploration; however, the effect of space radiation on the cardiovascular system is significantly less well understood.
