BACKGROUND: Preoperative muscle volume and body mass index (BMI) are associated with postoperative outcomes. Because esophagectomy for esophageal cancer (EC) is associated with high morbidity and because EC has a poor prognosis, this study investigated the association of preoperative skeletal muscle mass and nutritional status with postoperative outcomes. METHODS: The study analyzed 483 patients who underwent esophagectomy from 2009 to 2012. The cross-sectional area of the psoas muscle index (PMI) was measured at the third lumbar vertebral level using computed tomography...

PURPOSE: Image-based measurement of sarcopenia is an established predictor of a decreased outcome for a large variety of surgical procedures. Sarcopenia in elderly patients undergoing emergency abdominal surgery has not been well studied. This study aims to investigate the association between the total psoas area (TPA) and postoperative mortality after 90 days in a group of elderly emergency laparotomy patients. METHODS: We retrospectively reviewed the emergency CT-scans of 150 elderly patients from a consecutive cohort undergoing emergency abdominal surgery at our surgical center...

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: 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...

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...
