The method was found to be linear in the range of 0.5-5 μg/spot with correlation coefficient (R2) of 0.995 and 0.997 for strychnine and brucine, respectively. The developed method was successfully applied for the determination of strychnine and brucine in Ayurvedic formulations and blood samples. The method does not require any sophisticated instrument and handling skills and can be adopted for rapid analysis of strychnine and brucine in forensic toxicological laboratories. © The Author(s) 2020.

Studies during the A(H3N2)-dominated 2017-18 season showed slightly higher RVE for the cell-cultured vaccine compared to SD egg-based vaccines. We investigated the RVE of influenza vaccines among Medicare beneficiaries ages ≥65 years during the 2018-19 season. METHODS Retrospective cohort study using inverse probability of treatment weighting and Poisson regression to evaluate RVE in preventing influenza hospital encounters. RESULTS Among 12,777,214 beneficiaries, the egg-based adjuvanted (RVE 7.7%, 95% CI 3.9 to 11.4%) and high-dose (RVE 4.9%, 95% CI 1.7 to 8.1%) vaccines were marginally more effective than the egg-based quadrivalent vaccines. The cell-cultured quadrivalent vaccines were not significantly more effective than the egg-based quadrivalent vaccines (RVE 2.5%, 95% CI -2.4 to 7.3%). CONCLUSIONS We did not find major effectiveness differences between licensed vaccines used among the elderly during the 2018-19 season. Consistent wi
