Using mixed second-order structure functions, a compact exact law is derived for isothermal compressible Hall magnetohydrodynamic turbulence with the assumptions of statistical homogeneity, time stationarity and infinite kinetic/magnetic Reynolds numbers. The resulting law is written as the sum of a Yaglom-like flux term, with an overall expression strongly reminiscent of the incompressible law, and a pure compressible source. Being mainly a function of the increments, the compact law is Galilean invariant but is dependent on the background magnetic field if one is present. Only the magnetohydrodynamic source term requires multi-spacecraft data to be estimated whereas the other components, which include those introduced by the Hall term, can be fully computed with single-spacecraft data using the Taylor hypothesis. These properties make this compact law more appropriate for analysing both numerical simulations and in situ data gathered in space plasmas, in particular when only single-spacecraft data are available.

Background/Objective: Some case series and case report have shown the association between the risk of acute pancreatitis and use of selective serotonin reuptake inhibitors. The results of systematic studies were not consistent. Methods: A meta-analysis was performed to investigate the risk of acute pancreatitis associated with use of selective serotonin reuptake inhibitors. Results: There was no statistical association between the risk of acute pancreatitis and selective serotonin reuptake inhibitors use (odds ratio: 1.19, 95% confidence interval: 0.93-1.51). Conclusions: Despite reaching no statistical significance, the possibility of the association between the risk of acute pancreatitis and selective serotonin reuptake inhibitors use cannot be totally excluded.
