Muscle mass has been traditionally assessed by measuring paraspinal muscle areas at the level of third lumbar vertebra on computed tomography (CT). Neurological or neurosurgical patients seldom undergo CT scans region. Instead, temporal thickness (TMT), cross-sectional area (TMA) and radiodensity measured from head are readily available measures quality in these patient cohorts. The purpose this retrospective study was to establish CT-based reference values for TMT, TMA each decade age 0 100 years normalized sex, define cut-off subjects risk sarcopenia as defined European Working Group Sarcopenia Older People (EWGSOP). Subjects diagnosed with a concussion Oulu University Hospital between January 2014 December 2022 (n = 9254) were identified obtain population. significant pre-existing co-morbidities excluded. measured, measurement reliability quantified, sex-adjusted calculated decade. Quantile regression used model age-related changes morphomics. A total 500 [250 (50.0%) males] mean 49.2 ± 27.9 evaluated.

Purpose Recently, the temporalis muscle thickness on cranial CT scan was proposed as a surrogate marker for patients’ baseline frailty that correlates with outcome in primary and metastatic brain tumor patients. In this study, we investigated whether velocity of atrophy (TMA) affects patients cerebral metastases. Methods We analyzed radiological clinical data sets 96 who received craniotomy metastasis resection our institution. then correlated course after stratification atrophy. Results The median TMA 0.0016 mm/day. slow rate, overall survival significantly longer than fast rate (37.7 months versus 22.9, p = 0.0007). Furthermore, had progression-free postoperatively (7.6 4.38 months, <0.0001). (OS-PO) also (8.9 5.1, p=0002). Conclusion Based may represent an objective dynamic index potential prognostication

The prognosis of spontaneous intracerebral hemorrhage (ICH) is poor, but an accurately selected subset patients benefits from surgery. Loss muscle mass associated with various geriatric syndromes and poor overall physiological capacity. We investigated whether temporal thickness (TMT) index (TMI), non-invasive indicators whole-body mass, predict survival (OS) in surgically treated ICH. identified all evacuated spontenous supratentorial ICHs a single centre between 2014 2022. measured TMT TMI preoperative computed tomography scans, tested the prognostic capability these measurements for post-operative OS. Cut-off values were calculated to divide into low normal status groups according TMI. median age 63 included study was 67 years (IQR 57-72), 37 (59 %) males. mortality during follow-up period 36 months 1-79) significantly higher group, as assessed using cut-offs (67 % vs. 30 %, HR 2.65, 95 CI 1.23-5.65, 31 2.37, 1.11-5.04, respectively). association persisted when adjusted ICH score, pupillary blood pressure on admission (TMT 2.75, 1.27-5.96, 2.30, 1.07-4.97). provide information supplemental established outcome predictors These parameters may improve surgical patient selection detection at risk outcomes who might benefit intensified ancillary care.
