A Longitudinal Comparison of the Effects of Election Outcomes on System Legitimacy in the United Kingdom and United States

European Journal of Social Psychology, EarlyView.
ABSTRACT Using three‐wave panel data from the United Kingdom (N = 604) and the United States (N = 512), we examined changes in system‐legitimization across the 2024 electoral cycle and whether trajectories differed for electoral winners and losers. In both countries, system‐legitimization increased after the election, suggesting that elections function

Ketogenic diet for infantile epileptic spasms

Epilepsia Open, EarlyView.
Abstract Approximately half of all cases of Infantile Epileptic Spasms Syndrome (IESS) do not respond to vigabatrin and hormonal therapies. There is no clear consensus as to the second‐line therapy for IESS. Ketogenic diet (KD) has emerged as an effective treatment for certain drug‐resistant epilepsies and in many cases of IESS.
