The BRST Operator for the Large Superconformal Algebra
We review the detailed structure of the large superconformal algebra,
and construct its BRST operator which constitutes the main object for analyzing
strings. We then derive the general condition for the nilpotency of the
BRST operator and show that there exists a line of critical string
theories.Comment: Latex file, 16 pages, NBI-HE-94-1
Influenza vaccination for immunocompromised patients: summary of a systematic review and meta-analysis
Vaccination of immunocompromised patients is recommended in many national guidelines to protect against severe or complicated influenza infection. However, due to uncertainties over the evidence base, implementation is frequently patchy and dependent on individual clinical discretion. We conducted a systematic review and metaβanalysis to assess the evidence for influenza vaccination in this patient group. Healthcare databases and grey literature were searched and screened for eligibility. Data extraction and assessments of risk of bias were undertaken in duplicate, and results were synthesised narratively and using metaβanalysis where possible. Our data show that whilst the serological response following vaccination of immunocompromised patients is less vigorous than in healthy controls, clinical protection is still meaningful, with only mild variation in adverse events between aetiological groups. Although we encountered significant clinical and statistical heterogeneity in many of our metaβanalyses, we advocate that immunocompromised patients should be targeted for influenza vaccination
Influenza vaccination for immunocompromised patients: systematic review and meta-analysis from a public health policy perspective.
Immunocompromised patients are vulnerable to severe or complicated influenza infection. Vaccination is widely recommended for this group. This systematic review and meta-analysis assesses influenza vaccination for immunocompromised patients in terms of preventing influenza-like illness and laboratory confirmed influenza, serological response and adverse events
