Elderly patients are at a higher risk of morbidity and mortality after trauma, which is reflected through higher frailty indices. Data collection using existing frailty indices is often not possible because of brain injury, dementia, or inability to communicate with the patient. Sarcopenia is a reliable objective measure for frailty that can be readily assessed in CT imaging. In this study, we aimed to evaluate the effect of sarcopenia on the outcomes of geriatric blunt trauma patients. Left psoas area (LPA) was measured at the level of the third lumbar vertebra on the axial CT images. LPA was normalized for height (LPA mm2/m2) and after stratification by gender, sarcopenia was defined as LPA measurements in the lowest quartile. A total of 1175 patients consisting of 597 males and 578 females were studied. LPAs below 242.6 mm2/m2 in males and below 187.8 mm2/m2 in females were considered to be sarcopenic. We found sarcopenia in 149 males and 145 females. In multivariate analysis, sarcopenia was associated with a higher risk of in-hospital mortality (odds ratio [OR]: 1.61, 95% confidence interval [CI]: 1.01–2.56) and a higher risk of discharge to less favorable destinations (OR: 1.42, 95% CI: 1.05–1.97). Lastly, sarcopenic patients had an increased risk of prolonged hospitalization (hazard ratio: 1.21, 95% CI: 1.04–1.40).

Arteries And Veins

AbstractThe aim of this study was to describe origin, localisation and variations of renal arteries and veins in the rabbit. The study was carried out on 40 adult European rabbits. We prepared corrosion casts of the rabbit arterial and venous system. Spofacryl was used as the casting medium. In 75% of cases the origin of arteriae renales was located at the level of the third lumbar vertebra and in remaining 25% of cases arteria renalis dextra branched off at the level of the second lumbar vertebra. In 10% of cases we observed that the number of arteria renalis sinistra was doubled. We recorded also in one case the presence of arteria renalis accessoria for ren dexter. In 10% of cases we observed that the number of vena renalis sinistra was doubled. In 5% of cases two venae renales sinistrae arose from the kidney and subsequently, about 1 cm from opening to vena cava caudalis, they united to form a single vein. In 5% of cases two venae renales sinistrae arose from the kidney and subsequently, approximately 1 cm away from hilus renalis, they united. The obtained variations of the number of renal arteries were partially homologous to the human, but variations of renal veins were localized on the other side as in human.

Calculations are made of abdominal muscle loads and stresses associated with the development of intra-abdominal pressure during slow, symmetrical lifts. The muscles considered are the rectus, transversus and the external and internal obliques. Muscle loads and stresses have been calculated in an abdominal cross-section at about the level of the third lumbar vertebra. For four cases examined, maximum stress levels for men in the 25–35 years age range appear to be 3p-4p for the rectus muscles, 15p-25p for the transversus and 4p-6p for the obliques, where p is the intra-abdominal pressure. Corresponding figures for a man aged 66 years are about 8p, 21p and 8p respectively.

ObjectiveTo determine whether the sacral anatomical interspace landmark (SAIL) technique is more accurate than the classic intercristal line (ICL) technique in pregnant patients and to assess the percentage of clinical determinations above the third lumbar vertebra.MethodsIn this prospective, randomized, open-label trial, there were 110 singleton pregnant patients with gestational age greater than 37 weeks included. Selection procedure was a convenience sample of pregnant patients who presented for office visits or vaginal or cesarean delivery between March 15 and July 31, 2018, at a single-center obstetric tertiary care university hospital. Both techniques were evaluated by 2 physicians independently assessing each method. Before data collection, we hypothesized that the SAIL technique would be more accurate than the ICL technique in determining the L4-L5 interspace, and that the SAIL technique would produce more estimations below the third lumbar vertebra than the ICL technique. Therefore, the primary outcome was accuracy in identifying the L4-L5 lumbar interspace with SAIL vs ICL. The secondary outcome was difference in clinical assessments above the third lumbar vertebra. Both outcomes were measured via ultrasonography.ResultsPatients were 31 ± 5 years of age (mean ± SD) and had body mass index of 31.8 ± 5.7 kg/m2 and gestational age of 38.8 ± 1.1 weeks. A total of 110 patients were analyzed. SAIL correctly identified the L4-L5 interspace 49% of the time vs 8% using ICL (p < 0.0001). Estimations above L3 were 1% for SAIL vs 31% for ICL (p < 0.0001).ConclusionsOur study shows improved accuracy in identifying intervertebral space using the SAIL technique; this may prevent direct mechanical trauma to the conus medullaris when lumbar punctures are performed in pregnancy.Clinicaltrials.gov identifierNCT03433612.
