Purpose: Mepirapim is a new synthetic cannabinoid. We previously reported that the concentrations of unchanged mepirapim in whole blood and urine were much higher than those of other synthetic cannabinoids. To determine the postmortem distribution of mepirapim and acetyl fentanyl in the deceased individual, we established a standard addition method for detailed analysis by liquid chromatography-mass spectrometry (LC-MS) for quantification of these drugs. Methods: The LC-MS method was fully validated for linearity, extraction recovery, matrix effect and repeatability...

Although hepatitis E virus (HEV) transmission has been demonstrated after consumption of products containing infected pig liver, human cases can be also associated with other pig meat products, such as sausages. Data on HEV viremia and dissemination in muscle meat of infected animals are still sparse, especially during long-term infection. Previously, we have shown that experimental co-infection of pigs with HEV and porcine reproductive and respiratory syndrome virus (PRRSV) lengthens HEV infection up to 49 days and increases the likelihood of the presence of HEV RNA in the liver of the pig at a later stage of infection...

Impingement of hip arthroplasty components on soft tissues may adversely affect outcomes. An example is impingement of the cup on the ilio-psoas tendon, which has been reported in 0.4% to 8.3% of patients. Contributors to ilio-psoas tendon impingement (IPTI) can be categorised as anatomic (hypoplastic anterior wall), technical (inadequate anteversion and/or lower inclination, oversized cup, cement in contact with the tendon, and intra-muscular screw), and prosthetic (e.g., aggressive cup design, large-diameter head, resurfacing, and collared femoral prosthesis)...
