PURPOSE: Sarcopenia is a syndrome that is defined by the loss of skeletal muscle mass, quality, and strength. In adult patients with malignancies, the presence of sarcopenia is known to be correlated with a poor prognosis; however, there have been no reports on the influence of sarcopenia on malignant tumors in pediatric patients. In the present study, we investigated whether or not sarcopenia affects the prognosis of high-risk neuroblastoma. MATERIALS AND METHODS: Thirteen patients with high-risk neuroblastoma who were treated according to the standard protocol at our hospital from 2007 to 2016 were divided into a progression-free survival group (n = 8) and a relapse/death group (n = 5)...

OBJECTIVE: Sarcopenia, as assessed by computed tomography (CT)-based measurements of muscle mass, is an objective and patient-specific indicator of frailty, which is an important predictor of operative morbidity and mortality. Studies to date have primarily focused on psoas-defined sarcopenia, which may not be valid among patients with thoracic aortic disease. Using psoas sarcopenia as the reference for sarcopenia, the purpose of this study was to create and to validate a new thoracic-level method of measuring sarcopenia as a novel method to assess frailty among patients undergoing thoracic endovascular aortic repair...

Ageing, sarcopenia, and malnutrition are associated with quantitative and qualitative changes of body composition. There are several imaging modalities, including magnetic resonance imaging (MRI), for the assessment of trunk muscle tissue composition. In this study, we investigated the gender- and age-related changes in trunk muscle composition using chemical shift encoding-based water⁻fat MRI. A total of 79 healthy volunteers (26 men: 38.9 ± 10.4 years; 53 women: 39.5 ± 15.0 years) underwent 3T axial MRI using a six-echo multi-echo 3D spoiled gradient echo sequence, allowing for the calculation of the proton density fat fraction (PDFF) in the trunk muscles...

BACKGROUND: Morphomic studies have demonstrated a correlation between sarcopenia and clinical outcomes in septic patients. However, tendon morphomics has not yet been studied in this context. The purpose of the present study was to evaluate tendon morphology in septic patients through analytic morphomics. We hypothesized that morphomic analyses would reveal concomitant muscle and tendon wasting in sepsis patients. The results of this study may help to implement different rehabilitation modalities for critically ill patients...

BACKGROUND: Estimating sarcopenia by measuring psoas muscle density (PMD) has been advocated as a method to accurately predict post-operative morbidity. The aim of the present study was to determine whether the Timed Stair Climb (TSC) could be used to replace PMD measurements in predicting morbidity. METHODS: Patients were prospectively enrolled from March 2014-2015 and were eligible if they were undergoing an abdominal operation. PMD was measured using pre-operative CT scans obtained within 90 days of surgery...

BACKGROUND: Sarcopenia, a known component of frailty, defined by diminished cross-sectional area of the psoas muscles, is associated with poor outcomes after a range of surgical procedures. However, little is known of the relationship between sarcopenia of the psoas muscles (SPM) and long-term mortality, decline in pulmonary function, and graft failure after lung transplantation. METHODS: We reviewed patients who underwent primary lung transplantation at our institution from 2011 to 2014...

Proton-density fat fraction (PDFF) of the paraspinal muscles, derived from chemical shift encoding-based water-fat magnetic resonance imaging, has emerged as an important surrogate biomarker in individuals with intervertebral disc disease, osteoporosis, sarcopenia and neuromuscular disorders. However, quantification of paraspinal muscle PDFF is currently limited in clinical routine due to the required time-consuming manual segmentation procedure. The present study aimed to develop an automatic segmentation algorithm of the lumbar paraspinal muscles based on water-fat sequences and compare the performance of this algorithm to ground truth data based on manual segmentation...

BACKGROUND: Sarcopenia, an age-related loss of muscle mass and function, has been previously linked to an increased risk of morbidity, mortality, and infection after a variety of surgical procedures. This study is the first to evaluate the impact of the psoas-lumbar vertebral index (PLVI), a validated marker for central sarcopenia, on determining post-arthroplasty infection status. METHODS: This is a case-control, retrospective review of 30 patients with prosthetic joint infection (PJI) diagnosed by the Musculoskeletal Infection Society criteria compared to 69 control patients who underwent a total hip or knee arthroplasty...

BACKGROUND: The systemic inflammatory response (SIR) via host-tumor interactions has been termed the seventh hallmark of cancer, and several studies demonstrated that SIR might be a pivotal mediator for progression of cancer cachexia. The objective of this study was to clarify the correlation between sarcopenia and SIR in patients with colorectal cancer (CRC). METHODS: A total of 308 patients with CRC were enrolled in this study. Preoperative psoas muscle mass index and intramuscular adipose tissue content were evaluated using preoperative computed tomographic images, and the correlation between body composition status and several SIR markers, including C-reactive protein (CRP), serum albumin level, neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, and systemic immune-inflammation index (SII) was assessed using statistical methods...

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: Sarcopenia is a condition in which the amount of skeletal muscle decreases. Recent studies have suggested that sarcopenia is a risk factor for the incidence of postoperative complications, longer hospitalization, and a poorer prognosis. In this study, we examined the impact of sarcopenia in association with a history of hemodialysis in renal transplantation patients. METHODS: A total of 157 patients who underwent renal transplantation at Yokohama City University Medical Center (Yokohama, Japan) from 2005 to 2016 were analyzed in this study...

OBJECTIVES: A growing body of evidence shows that frailty and functional performance predict liver transplant outcomes. The Organ Procurement and Transplant Network uses the Karnofsky Performance Status scale to adjust for transplant center case mix in assessing quality measures. This study explores the strength of the relationship between Karnofsky Performance Status scores and objective measures of frailty. MATERIALS AND METHODS: This observational study includes 136 adult, first-time liver transplant recipients at UMass Memorial (2006-2015) who had 2 abdominal computed tomography scans available (at ≤ 90 days pretransplant and ≥ 7 days before that)...
