A 62-year-old woman receiving romosozumab for 3 months underwent extreme lateral interbody fusion (XLIF) for lumbar degenerative spondylolisthesis. From 1 week after surgery, she experienced gradually...
We report a rare case of myositis ossificans in bilateral psoas major muscles following XLIF surgery, possibly influenced by intraoperative manipulation and romosozumab treatment. Etidronate administr...
Sarcopenia is a common problem in patients with HCC. We aimed to evaluate the prognostic and predictive value of baseline transversal psoas muscle thickness (TPMT) measurement in patients with HCC und...
HCC patients treated with programmed death ligand 1-based therapies between June 2016 and October 2022 at the Vienna General Hospital (n = 80) and the Hôpital Beaujon Clichy (n = 96) were included and...
Overall, 176 patients (age: 66.3±11.7 y; male: n=143, 81%, Barcelona-Clinic Liver Cancer C: n=121, 69%) were included, of which 131 (74%) exhibited cirrhosis. Interreader agreement for the diagnosis o...
Evaluation of sarcopenia using TPMT measurement is reliable and identifies HCC patients with a dismal prognosis and response to immunotherapy....
The function of the paraspinal muscles and especially the psoas muscle in maintaining an upright posture is not fully understood. While usually considered solely as a hip flexor, the psoas muscle and ...
A retrospective review including patients undergoing posterior lumbar fusion surgery between 2014 and 2021 at a tertiary care center was conducted. Patients with a preoperative lumbar magnetic resonan...
One hundred ninetypatients (57.9% female) with a median age of 64.7 years and median BMI of 28.3 kg/m...
As the FI...
The analysis of the psoas muscle in morphological and functional imaging has proved to be an accurate approach to assess sarcopenia, i.e. a systemic loss of skeletal muscle mass and function that may ...
To assess and compare the value of psoas muscle thickness at the level of the third lumbar (L3) vertebra (TPML) or umbilicus (TPMU) and skeletal muscle index (SMI) for diagnosing sarcopenia and predic...
Two hundred forty-nine patients undergoing TIPS were included in this retrospective study. The cut-offs of L3-SMI for sarcopenia were 42.0 cm...
Compared with TPMU/height, TPML/height was more consistent with L3-SM for the diagnosis of sarcopenia (Kappa coefficient: 0.63 vs. 0.36 in men; 0.61 vs. 0.45 in women). The Cox analysis showed that bo...
TPMU/height and TPML/height have a similar survival prognostic value as L3-SMI. TPML/height has better consistency with L3-SMI in diagnosing sarcopenia and is a more stable alternative to L3-SMI for d...
Endovascular aneurysm repair conversion (EVAR-c) is increasingly reported and known to be technically complex and physiologically demanding. It has been proposed that pragmatic anthropomorphic measure...
A retrospective single-center review of all AAA repairs was performed (2002-2019) and EVAR-c procedures were subsequently analyzed (n = 153). Cross-sectional PMA at the mid-body of the L3 vertebrae wa...
Patients with low PMA were older (77 vs. 72 years; P = 0.002), more likely to be female (27% vs. 5%; P < 0.001), and had reduced body mass index (26 vs. 29 kg/m...
Among EVAR-c patients, subjects with low preoperative PMA had higher rates of postoperative complications and worse overall survival. PMA assessments may be a useful adjunct to supplement traditional ...
This study aimed to analyze the time-course of the physical properties of the psoas major muscle (PM) before and after exercise using magnetic resonance elastography (MRE). Muscle stiffness is one of ...
Sarcopenia is characterized by reduced skeletal muscle volume and is a condition that is prevalent among elderly patients and associated with poor prognosis as a comorbidity in malignancies. Given the...
The subjects were 150 patients aged ≥ 80 years with CRC who underwent primary tumor resection at Juntendo University Hospital between 2004 and 2017. 3D-CT measurement of PV and conventional CT measure...
The S:nS ratios were 15:135 for the PV method and 52:98 for the PA method. There was a strong positive correlation (r = 0.66, p < 0.01) between PVI (psoas major muscle volume index) and PAI (psoas maj...
The PV method for identifying sarcopenia in elderly patients with CRC is more practical and sensitive for prediction of a poor prognosis compared to the conventional method....
The aim of this study is to determine whether the sarcopenia index (SI) is a viable measure of muscle mass in pediatric patients with brain tumors....
Retrospectively enrolled patients (1-16 years) who had serum creatinine (Cr) and cystatin C (CysC) levels evaluated within 28 days of an abdomen magnetic resonance imaging scan for the lumbar vertebra...
The SI z score had no correlation with tPMA z score (r = 0.004). Both Cr and CysC levels were positively correlated with tPMA in z scores (r = 0.249 and 0.320). tPMA strongly correlated with body mass...
The correlation of SI to muscle mass is very weak in our sample of pediatric patients with brain tumor. Its viability as biomarker for sarcopenia needs more study....
The creatinine height index (CHI) is an estimate of lean body mass. We hypothesize that a modified CHI estimate using serum creatinine (sCr) levels in patients with normal renal function when performe...
The urine CHI (uCHI) was calculated using the 24-h urine sample. The serum-derived estimated CHI (sCHI) was calculated using the sCr on admission. Correlation between abdominal computed tomography ima...
A total of 45 patients were enrolled, all with a significant injury burden (median injury severity score [ISS] = 25; interquartile range, 17-35). The calculated sCHI on admission was 71.0% (SD = 26.9%...
The CHI calculated from the initial sCr is not an appropriate estimate of uCHI in critically ill trauma patients and is not a valid measure of psoas muscle mass in this setting....
