Nutrients, Journal Year: 2022, Volume and Issue: 14(3), P. 687 - 687

Published: Feb. 6, 2022

Evaluating muscle mass and function among stroke patients is important. However, evaluating volume not easy due to the disturbances of consciousness paresis. Temporal thickness (TMT) has been introduced as a novel surrogate marker for mass, function, nutritional status. We herein performed narrative literature review on temporal understand current meaning TMT in clinical practice.

Age- and sex-adjusted CT-based reference values for temporal muscle thickness, cross-sectional area and radiodensity

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

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).

Easily Created Prediction Model Using Automated Artificial Intelligence Framework (Prediction One, Sony Network Communications Inc., Tokyo, Japan) for Subarachnoid Hemorrhage Outcomes Treated by Coiling and Delayed Cerebral Ischemia

Cureus, Journal Year: 2021, Volume and Issue: unknown

Published: June 16, 2021

Introduction Reliable prediction models of subarachnoid hemorrhage (SAH) outcomes and delayed cerebral ischemia (DCI) are needed to decide the treatment strategy. Automated artificial intelligence (AutoAI) is attractive, but there few reports on AutoAI-based for SAH functional DCI. We herein made using an AutoAI framework, Prediction One (Sony Network Communications Inc., Tokyo, Japan), compared it other previous statistical scores. Methods used open dataset 298 patients, who were with non-severe neurological grade treated by coiling. Modified Rankin Scale 0-3 at six months was defined as a favorable outcome DCI occurrence another outcome. randomly divided them into 248-patient training 50-patient test dataset. model 5-fold cross-validation. evaluated area under curves (AUCs) created models. Those modified SAFIRE score Fisher computed tomography (CT) scale predict outcomes. Results The AUCs in 0.994 0.801, those 0.969 0.650. calculated 0.844 0.892. CT 0.577 0.544. Conclusions easily quickly models' not inferior despite easiness.

Significance of Temporal Muscle Thickness in Chronic Subdural Hematoma

Journal of Clinical Medicine, Journal Year: 2022, Volume and Issue: 11(21), P. 6456 - 6456

Published: Oct. 31, 2022

Background: Reduced temporal muscle thickness (TMT) was verified as an independent negative prognostic parameter for outcome in brain tumor patients. Independent thereof, chronic subdural hematoma (CSDH) is a neurosurgical condition with high recurrence rates and unreliable risk models poor outcome. Since sarcopenia associated outcome, we investigated the possible role of TMT clinical course CSDH Methods: This investigation single-center retrospective study on patients CSDH. We analyzed radiological data sets 171 surgically treated at University Hospital from 2017 to 2020. Results: Our analysis showed significant association between low-volume increased volume (p < 0.001), discharge reduced performance status 3 months 0.002).

Frailty in Traumatic Brain Injury—The Significance of Temporal Muscle Thickness

Journal of Clinical Medicine, Journal Year: 2023, Volume and Issue: 12(24), P. 7625 - 7625

Published: Dec. 11, 2023

Temporal muscle thickness (TMT) on cranial CT scans has recently been identified as a prognostic imaging parameter for assessing patient's baseline frailty. Here, we analyzed whether TMT correlates with Traumatic brain injury (TBI) severity and it can be used to predict outcome(s) after TBI. We the radiological clinical data sets of 193 patients TBI who were admitted our institution correlated outcomes stratification TMT. Our analyses showed significant association between high increased risk intracranial hemorrhage (p = 0.0135) but improved mRS at 6 months 0.001) compared low Congruent such findings, lower was associated falls reduced < 0.0001 p 0.0001). High robustly head trauma sequelae also good in patients. These findings consolidate significance an objective marker frailty patients; measurements may ultimately leveraged indicators.

Metastases are the most frequent intracranial malignant tumors in adults. While Karnofsky Performance Status (KPS) and Clinical Frailty Scale (CFS) known to have significant impact on overall survival (OS), temporal muscle thickness (TMT) has been postulated be a promising new parameter estimate prognosis. Patients who received resection of one three brain metastases our institution were included. Temporal was measured preoperative MRI scans according standardized protocol.
