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...

BACKGROUND: Malnutrition and muscle wasting are common in patients with end-stage liver disease (ESLD), yet go underdiagnosed. Frequently used indices of nutritional status, such as body mass index, are inflated in patients with ESLD due to a fluid overloaded state. Previous work has demonstrated a strong association between psoas muscle area, a surrogate for sarcopenia, and worse survival following liver transplantation; however, the impact of sarcopenia on post liver transplant outcomes in patients with nonalcoholic steatohepatitis (NASH) cirrhosis has not been evaluated...

INTRODUCTION: The aim of our study was to assess the correlation between frailty & sarcopenia and impact of each condition on outcomes in geriatric trauma patients. METHODS: We performed a four-year (2013-2016) secondary analysis of our prospectively maintained frailty database and included all trauma patients age ≥65 y who had CT-abdomen. Trauma-Specific-Frailty-Index (TSFI) was used to calculate frailty. Patients were classified as non-frail or frail. Sarcopenia was defined as the lowest sex-specific-quartile of total-psoas-index (TPI)...

BACKGROUND: Low skeletal muscle quantified using computed tomography (CT) scans is associated with morbidity and mortality among cancer patients. However, existing methods to assess skeletal muscle from CT are time-consuming, expensive, and require training. Clinic-friendly tools to screen for low skeletal muscle in cancer patients are urgently needed. METHODS: We included 807 scans from non-metastatic colorectal cancer patients. With the digital ruler available in most radiological software, we implemented an abbreviated method to assess skeletal muscle area at the third lumbar vertebra (L3), which consisted of assessing the height and width of the psoas and paraspinal muscles and computing their combined 'linear area' in centimetres squared (cm2 )...

Sarcopenia as defined by reduced skeletal muscle area (SMA) on cross-sectional abdominal imaging has been proposed as an objective measure of malnutrition, and is associated with both waitlist mortality and post-transplant complications in patients with cirrhosis. SMA, however, has never been validated against the gold-standard measurement of total body protein (TBP) by in vivo neutron activation analysis (IVNAA). Furthermore, overhydration is common in cirrhosis and its effect on muscle area measurement remains unknown...

AIM: Hepatocellular carcinoma (HCC) patients with sarcopenia have a poor survival, but there are no predictive markers for survival relating to muscle mass and liver function. Therefore, we investigated whether the ratio between estimated glomerular filtration rates of serum creatinine (Scre) and serum cystatin C (Scys) (eGFRcre/eGFRcys) can be used as a predictive marker of survival in HCC patients. METHODS: First, the correlation between Scre/Scys ratio and muscle mass was examined in 50 patients with chronic liver disease...

Background: Ongoing evidence suggests that sarcopenia adversely affects outcomes in cirrhosis. The aim of this study was to evaluate muscle fat infiltration as a component of sarcopenia and its prognostic value in this setting. Methods: In 98 consecutive patients with cirrhosis, muscle density was measured during a computed tomography scan at the level of the fourth to fifth lumbar (L4) vertebrae. Univariate and multivariate Cox regression analysis was used to determine predictors of survival...

BACKGROUND: Sarcopenia may be an indicator of frailty. We used the total psoas area index (TPAI) to identify sarcopenia and evaluated the effect of preoperative TPAI on outcomes after descending thoracic aortic aneurysm (DTAA) repair. METHODS: Patients with DTAA between 2007 and 2015 who were undergoing thoracic endovascular aortic repair (TEVAR) and open surgical repair (OSR) with available preoperative imaging were analyzed. Sarcopenia was defined as TPAI <6...

Background: Total psoas area (TPA), a marker of sarcopenia, has been used as an independent predictor of clinical outcomes in gastrointestinal (GI) cancers as a proxy for frailty and nutritional status. Our study aimed to evaluate whether TPA, in contrast to traditional measurements of nutrition like body mass index (BMI) and body surface area (BSA), was predictive of outcomes in borderline resectable pancreatic cancer (BRPC) and locally advanced pancreatic cancer (LAPC) patients receiving stereotactic body radiation therapy (SBRT)...

OBJECTIVE: Sarcopenia is associated with poor outcomes in patients undergoing surgery for pancreatic ductal adenocarcinoma (PDAC). However, few studies have assessed changes in sarcopenia during multimodality therapy or its effect on overall survival (OS). METHODS: Computed tomography (CT) total psoas area index (TPAI) and weighted average Hounsfield units (HU) were measured at each treatment interval in patients with resectable PDAC. Four cohorts were compared: 1...

BACKGROUND: Sleeve gastrectomy (SG) has become the primary procedure for many bariatric teams and staple-line leak represents its most feared complication. Sarcopenic obesity combines the risks of obesity and depleted lean mass leading possibly to an inferior surgical outcome after abdominal surgery. OBJECTIVES: The aim of this study was to evaluate the existence of a potential link between radiologically determined sarcopenic obesity and staple-line leak risk after SG...

The aging population is becoming a primary global problem. The most important alteration that occurs in the body with age, is the loss of skeletal muscle. Previously, sarcopenia, which is associated with the loss of skeletal muscle, has been reported to be associated with the prognosis of cancer and complications. The present study investigated the importance of sarcopenia with regard to the prognosis or postoperative complications of upper urothelial cancer patients who underwent nephro-ureterectomy. A total of sixty patients (male, n=44; female, n=16) underwent nephro-ureterectomy for upper urothelial carcinoma...

BACKGROUND: Computed tomography (CT) scans performed during routine hospital care offer the opportunity to quantify skeletal muscle and predict mortality and morbidity in intensive care unit (ICU) patients. Existing methods of muscle cross-sectional area (CSA) quantification require specialized software, training, and time commitment that may not be feasible in a clinical setting. In this article, we explore a new screening method to identify patients with low muscle mass. METHODS: We analyzed 145 scans of elderly ICU patients (≥65 years old) using a combination of measures obtained with a digital ruler, commonly found on hospital radiological software...

BACKGROUND: Sarcopenia is defined as the loss of skeletal muscle mass and function associated with aging. Muscle mass can be reliably and accurately quantified using clinical CT scans but reference measurements are lacking, particularly in healthy US populations. METHODS: Two-phase CT scans from healthy kidney donors (age 18-40) at the University of Michigan between 1999-2010 were utilized. Muscle mass was quantified using two thoracic and two lumbar muscle cross-sectional area (CSA) measures...

Background: Sarcopenia has been associated with increased adverse outcomes after major abdominal surgery. Sarcopenia defined as decreased muscle volume or increased fatty infiltration may be a proxy for frailty. In conjunction with other preoperative clinical risk factors, radiographic measures of sarcopenia using both muscle size and density may enhance prediction of outcomes after pancreaticoduodenectomy (PD) for malignancy. Methods: Preoperative computed tomography (CT) scans of patients undergoing PD for malignancy were analyzed from a prospective pancreatic surgery database...

OBJECTIVE: Frailty is associated with adverse events, length of stay, and nonhome discharge after vascular surgery. Frailty measures based on walking-based tests may be impractical or invalid for patients with walking impairment from symptoms or sequelae of vascular disease. We hypothesized that grip strength is associated with frailty, comorbidity, and cardiac risk among patients with vascular disease. METHODS: Dominant hand grip strength was measured during ambulatory clinic visits among patients with vascular disease (abdominal aortic aneurysm [AAA], carotid stenosis, and peripheral artery disease [PAD])...

Muscle weakness is one of the most serious problems during chemotherapy for childhood hematological malignancies. It may be caused by long-term hospitalization, unfavorable physical conditions, and restricted activities. Although the concept of sarcopenia is becoming widely recognized, especially in geriatric medicine, there have been few reports about sarcopenia in pediatric patients with hematological malignancies. A total of 47 consecutive first-onset acute lymphoblastic leukemia (ALL) patients who underwent induction therapy between January 2011 and September 2016 were investigated...

Background: Sarcopenia is an independent predictor of clinical outcomes in multiple gastrointestinal cancers. Total psoas area (TPA), as measured on a single cross-sectional CT image at the L4 vertebral body level, has been correlated with sarcopenia. We sought to evaluate whether TPA was predictive of acute grade ≥3 toxicity, pathologic response, and overall survival in patients with locally advanced esophageal cancer receiving tri-modality therapy. Methods: An institutional database of esophageal cancer patients treated with neoadjuvant chemoradiation followed by surgery was queried...
