INTRODUCTION: Emergency laparotomy in patients over the age of 80 is associated with high morbidity and mortality. Accurate risk prediction in this patient population is desirable. Sarcopenia has been shown to be associated with outcome in multiple clinical settings and the psoas major muscle as measured on computed tomography (CT) imaging has been demonstrated as a marker of sarcopenia. We aim to assess the use of psoas major measurement on pre-operative CT as a prognostic indicator in over-80s undergoing emergency laparotomy and compare this measurement to P-POSSUM...

BACKGROUND: The prognosis of peripheral artery disease (PAD) and comorbid sarcopenia is poor. Some reports indicate that the computed tomography (CT) value of skeletal muscle, which reflects intramuscular fat deposition as well as skeletal muscle mass, is considered a marker of sarcopenia. However, it remains unclear if skeletal muscle area and CT value are associated with poor outcomes in patients with PAD. Methods and Results: Psoas muscle area and CT value were measured by manual trace at the level of the third lumbar vertebral body in 327 consecutive patients with PAD undergoing endovascular therapy (EVT)...

BACKGROUND: Endometrioma generally shows higher intracystic signal intensity (SI) than mucinous cystadenoma (MCA) on T1 -weighted imaging (T1 WI). Nonendometrioma-associated malignant ovarian epithelial tumors (nonendometrioma group) often show higher intracystic SI than benign tumors on T1 WI, while the converse is true for endometrioma and endometrioma-associated malignant tumors (endometrioma group). However, it is sometimes difficult to differentiate between hemorrhagic and mucinous content based on SI on T1 WI...

This case report centres on the post-mortem distribution of the synthetic cannabinoid MDMB-CHMICA and its metabolites in the case of a 27-year-old man found dead after falling from the 24th floor of a high-rise building. Toxicological analysis of post-mortem samples confirmed, besides consumption of the synthetic cannabinoids MDMB-CHMICA (1.7 ng/mL femoral blood) and EG-018, the abuse of THC (9.3 ng/mL femoral blood), amphetamine (1050 ng/mL femoral blood), MDMA (275 ng/mL femoral blood), and cocaine. Regarding EG-018 and cocaine, only traces were detected in heart blood as well as in the brain (EG-018) and urine (cocaine), respectively, which is why no quantification was conducted in the femoral blood sample...
