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...

Beef M. longissimus lumborum (LL) and M. psoas major (PM) muscles showed significant differences in various meat quality attributes (such as pH, lipid oxidation, and color stability). To better understand the underlying molecular variations between LL and PM, the proteome changes at early postmortem periods were investigated by comparative proteomic approach. A total of 504, 519, and 487 mutual proteins of each comparison (LL vs. PM at 1 h, 12 h, and 24 h, respectively) were successfully identified. Among these proteins, 238 proteins were differentially expressed in LL samples compared to PM ones...

BACKGROUND: Cam-type femoroacetabular impingement (FAI) is a causative factor for hip pain and early hip osteoarthritis. Although cam FAI can alter hip joint biomechanics, it is unclear what role muscle forces play and how they affect the hip joint loading. Purpose/Hypothesis: The purpose was to examine the muscle contributions and hip contact forces in individuals with symptomatic cam FAI during level walking. Patients with symptomatic cam FAI would demonstrate different muscle and hip contact forces during gait...

Fresh beef color stability is a muscle-specific trait. Mitochondria remain biochemically active in postmortem beef muscles and influence meat color. Although several intrinsic factors governing muscle-specific beef color have been studied extensively, the role of mitochondrial functionality in muscle-dependent color stability is yet to be examined. Therefore, the objective of this study was to examine mitochondrial oxygen consumption rate (OCR), mitochondrial metmyoglobin reducing activity (MMRA), and instrumental color attributes in beef Longissimus lumborum (LL) and Psoas major (PM) during retail display...

This study investigated the effects of CO-pretreatments on three bovine muscles: Psoas major (PM), Gluteus medius (GM) and Semitendinosus (ST) on colour stability and quality attributes under anaerobic conditions. Steaks were exposed to one of four pretreatments: 1% CO for 5 h, 5% CO for 5 h, 1% CO for 24 h, with 60% CO2, (balance N2 ) or untreated (control) and then vacuum packaged and displayed (28 days at 2 °C). CO pretreatments improved redness for colour labile muscles (PM and GM). The optimum CO pretreatment was 1% for 5 h as this induced surface redness while discolouring (a* = 12, C* = 16) by the use-by-date (28 days)...
