Li Y, Chen J, Tang Y, Lin T, Song T. Effect of pretransplant sarcopenia on patient and graft outcomes in solid organ transplant recipients: A systematic review and meta-analysis. Asian J Surg 2024; 47:1723-1733. [PMID: 38169165 DOI: 10.1016/j.asjsur.2023.12.118] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 11/10/2023] [Accepted: 12/15/2023] [Indexed: 01/05/2024] Open
Abstract
The relationship between sarcopenia and prognosis in solid organ transplantation recipients (SOTr) remains unverified. We aimed to quantify the prevalence of pretransplant sarcopenia and its effect on patient and graft survival in SOTr. We used PubMed, EMBASE, Cochrane Library and Web of Science to search relevant studies published in English (from inception to December 31, 2021). Prospective and retrospective cohort studies that reported the prevalence of sarcopenia before transplant or the association between sarcopenia and clinical outcomes in SOTr were included. Primary outcomes were the prevalence of sarcopenia and its impact on patient and graft survival. Secondary outcomes included perioperative complications, acute rejection, length of hospital stay, length of intensive care unit stay (ICU LOS) and early readmission. Thirty-nine studies involving 5792 patients were included. Pooled prevalence of sarcopenia amongst SOTr candidates was 40 % (95 % confidence interval [CI]: 34%-47 % and I2 = 97 %). Sarcopenia was associated with increased risk of death (hazard ratio [HR] = 1.87, 95 % CI: 1.46-2.41 and I2 = 60 %), poor graft survival (HR = 1.71, 95 % CI: 1.16-2.54 and I2 = 57 %) and increased liver graft loss (HR = 1.43, 95 % CI: 1.03-1.99 and I2 = 38 %). Patients with sarcopenia demonstrated increased incidence of perioperative complications (risk ratio [RR] = 1.34, 95 % CI: 1.17-1.53 and I2 = 40 %), long ICU LOS (mean difference = 2.31 days, 95 % CI: 0.58-4.04 and I2 = 97 %) and decreased risk of acute rejection (RR = 0.61, 95 % CI: 0.42-0.89 and I2 = 0 %). In Conclusion, sarcopenia is prevalent in SOTr candidates and associated with death and graft loss. Identifying sarcopenia before transplantation and intervening may improve long-term outcomes.

Abstract
Patients who undergo solid organ transplant can have an extensive and challenging postoperative course. The chronicity of the disease state prior to transplant in combination with transplant-specific complications and immunosuppressant medications can lead to distinct challenges that are not observed in other critically ill patients. Although the manifestation of posttransplant complications may be specific to the organ being transplanted, there are common transplant challenges that affect nutrition therapy in these patients. Effects of malnutrition, metabolic aberrations, and posttransplant organ dysfunction should be considered when developing a nutrition care plan for patients in the immediate posttransplant phase. This article addresses the various complications that can arise in the immediate posttransplant phase among patients undergoing solid organ transplant and the appropriate nutrition interventions or considerations for this specialized patient population.

[PMID: 37836461 PMCID: PMC10574362 DOI: 10.3390/nu15194179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 09/14/2023] [Accepted: 09/21/2023] [Indexed: 10/15/2023] Open
Abstract
INTRODUCTION Not much is known about the significance of nutritional status and support in transplant surgery, least of all in simultaneous pancreatic and kidney transplantation. Malnutrition in the context of simultaneous pancreatic-kidney transplantation seems to be complex and a still poorly investigated problem. Since SPKTX is highly qualified and also has a small volume procedure, it is difficult to obtain data from large cohorts of patients. The aim of this article is to gather existing evidence and information about the subject, as well as to elicit some questions and goals for the future. METHODS We searched through the Pub-Med database using the keywords "pancreas and kidney transplantation" combined with "nutritional risk", "nutritional status", "malnutrition", "nutritional intervention", and "frailty", finding a total of 4103 matching results. We then narrowed it down to articles written in English with the full text available. We also researched through the references of articles most accurately matching our researched terms. RESULTS There are numerous tools that have been investigated for the screening of malnutrition, such as the NRI index, PNI index, NLR, SGA scale, and NRS-2002 scale, each of which proved to be of some use in predicting patient outcomes in different surgical settings. Since all of them differed in components and assessed parameters and, in the absence of more sensitive or infallible indicators, the most reasonable approach seems to evaluate them jointly. CONCLUSION It is important to underline the necessity of nutritional screening and the subsequent introduction of adequate therapy while awaiting transplantation in an attempt to improve results. Considering the complexity of surgical procedures and the severity of underlying diseases with their intense metabolic components, the patient's nutritional status seems to significantly influence results. Consequently, nutritional risk assessments should be a part of the routine care of patients qualified for transplantation.

Sarcopenia of kidney transplant recipients as a predictive marker for reduced graft function and graft survival after kidney transplantation. Langenbecks Arch Surg 2023; 408:103. [PMID: 36826595 PMCID: PMC9958183 DOI: 10.1007/s00423-023-02836-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Accepted: 02/13/2023] [Indexed: 02/25/2023]
Abstract
PURPOSE The association between sarcopenia of kidney transplant recipients and outcome after kidney transplantation (KT) has not yet been fully understood and is still considered controversial. The aim of our study was to analyze the impact of pre-transplant sarcopenia on graft function, postoperative complication rates, and survival of the patients after renal transplantation. METHODS In this retrospective single-center study, all patients who underwent KT (01/2013-12/2017) were included. Demographic data, rejection rates, delayed graft function, and graft and patient survival rates were analyzed. Sarcopenia was measured in computed tomography images by the sex-adjusted Hounsfield unit average calculation (HUAC). RESULTS During the study period, 111 single KTs (38 women and 73 men) were performed. Living donor kidney transplants were performed in 48.6%. In total, 32.4% patients had sarcopenia. Sarcopenic patients were significantly older (59.6 years vs. 49.8 years; p < 0.001), had a higher body mass index (BMI = 27.6 kg/m2 vs. 25.0 kg/m2; p = 0.002), and were more likely to receive deceased donor kidneys (72.2% vs. 41.3%; p = 0.002). Interestingly, 3 years after KT, the creatinine serum levels were significantly higher (2.0 mg/dl vs. 1.5 mg/dl; p = 0.001), whereas eGFR (39.9 ml/min vs. 53.4 ml/min; p = 0.001) and graft survival were significantly lower (p = 0.004) in sarcopenic transplant recipients. Sarcopenic patients stayed in hospital significantly longer postoperatively than those who were non-sarcopenic. CONCLUSIONS At the time of kidney transplantation, sarcopenia was found to predict reduced long-term graft function and diminished graft survival after KT. The early identification of sarcopenic patients can not only enable an optimized selection of recipients, but also the initiation of pre-habilitation programs during the waiting period.

Abstract
Well-selected patients with kidney disease and diabetes mellitus who undergo simultaneous kidney-pancreas transplantation often experience dramatic improvements in quality of life and long-term survival compared to those who remain on medical therapy. Over the past several years the importance of frailty in the pancreas transplant candidate and recipient populations has grown. More patients with advanced age have entered the waitlist, and complications from prolonged diabetes, even in younger patients, have created increased evidence of risk for frailty. Given these concerns, and the broad challenges facing pancreas transplantation volumes overall, we generated this review to help establish the impact and implications. We summarize the interplay of immunological factors, aging, environmental factors, diabetes mellitus, and chronic kidney disease that put these patients at risk for frailty. We discuss its measurement and recommend a combination of two instruments (both well-validated and one entirely objective). We describe the outcomes for patients before and after pancreas transplantation who may have frailty, and what interventions can be taken to mitigate its effects. Broader investigation into frailty in the pancreas transplant population is needed to better understand how to select patients for pancreas transplantation and to how manage its consequences thereafter.

Abstract
Introduction: Sarcopenia, defined as low skeletal muscle mass and poor muscle function, has been associated with worse postoperative recovery. This study aims to evaluate the significance of low muscle mass in the elderly who require emergency surgeries and the postoperative outcomes.
Method: Data from the emergency laparotomy database were retrieved from Khoo Teck Puat Hospital, Singapore, between 2016 and 2019. A retrospective analysis was performed on patients aged 65 years and above. Data collected included skeletal muscle index (SMI) on computed tomography scan, length of stay, complications and mortality. Low muscle mass was determined based on 25th percentile values and correlation with previous population studies.
Results: A total of 289 patients were included for analysis. Low muscle mass was defined as L3 SMI of <22.09cm2/m2 for females and <33.4cm2/m2 for males, respectively. Seventeen percent of our patients were considered to have significantly low muscle mass. In this group, the length of stay (20.8 versus 16.2 P=0.041), rate of Clavien-Dindo IV complications (18.4% vs 7.5% P=0.035) and 1-year mortality (28.6% vs 14.6%, P=0.03) were higher. Further multivariate analysis showed that patients with low muscle mass had increased mortality within a year (odds ratio 2.16, 95% confidence interval 1.02–4.55, P=0.04). Kaplan-Meier analysis also shows that the 1-year overall survival was significantly lower in patients with low muscle mass.
Conclusion: Patients with low muscle mass have significantly higher post-surgical complication rates and increased mortality.

Pancreas Transplantation in Minorities including Patients with a Type 2 Diabetes Phenotype. URO 2022. [DOI: 10.3390/uro2040026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 11/06/2022]
Abstract
Background: Prior to year 2000, the majority of pancreas transplants (PTx) were performed as simultaneous pancreas-kidney transplants (SPKTs) in Caucasian adults with end stage renal failure secondary to type 1 diabetes mellitus (T1DM) who were middle-aged. In the new millennium, improving outcomes have led to expanded recipient selection that includes patients with a type 2 diabetes mellitus (T2DM) phenotype, which excessively affects minority populations. Methods: Using PubMed® to identify appropriate citations, we performed a literature review of PTx in minorities and in patients with a T2DM phenotype. Results: Mid-term outcomes with SPKT in patients with uremia and circulating C-peptide levels (T2DMphenotype) are comparable to those patients with T1DM although there may exist a selection bias in the former group. Excellent outcomes with SPKT suggests that the pathophysiology of T2DM is heterogeneous with elements consisting of both insulin deficiency and resistance related to beta-cell failure. As a result, increasing endogenous insulin (Cp) production following PTx may lead to freedom checking blood sugars or taking insulin, better metabolic counter-regulation, and improvements in quality of life and life expectancy compared to other available treatment options. Experience with solitary PTx for T2DM or in minorities is limited but largely mirrors the trends reported in SPKT. Conclusions: PTx is a viable treatment option in patients with pancreas endocrine failure who are selected appropriately regardless of diabetes type or recipient race. This review will summarize data that unconventional patient populations with insulin-requiring diabetes may gain value from PTx with an emphasis on contemporary experiences and appropriate selection in minorities in the new millennium.

Abstract
OBJECTIVES We investigated how preoperative sarcopenia and perioperative muscle mass changes affect postoperative nutritional parameters in patients undergoing pancreatectomy. METHODS This study included 164 patients undergoing pancreatectomy between January 2011 and October 2018. Skeletal muscle area was measured by computed tomography before and 6 months after surgery. Sarcopenia was defined as the lowest sex-specific quartile, and patients with muscle mass ratios less than -10% were classified into the high-reduction group. We examined the relationship between perioperative muscle mass and postoperative nutritional parameters 6 months after pancreatectomy. RESULTS There were no significant differences in nutritional parameters between the sarcopenia and nonsarcopenia groups at 6 months after surgery. In contrast, albumin (P < 0.001), cholinesterase (P < 0.001), and prognostic nutritional index (P < 0.001) were lower in the high-reduction group. According to each surgical procedure, albumin (P < 0.001), cholinesterase (P = 0.007), and prognostic nutritional index (P < 0.001) were lower in the high-reduction group of pancreaticoduodenectomy. In distal pancreatectomy cases, only cholinesterase (P = 0.005) was lower. CONCLUSIONS Postoperative nutritional parameters were correlated with muscle mass ratios but not with preoperative sarcopenia in patients undergoing pancreatectomy. Improvement and maintenance of perioperative muscle mass are important to maintain good nutritional parameters.

Abstract
Postoperative pancreatic fistula (POPF) is one of the most critical complications after pancreatic surgery. The relationship between sarcopenia and outcomes following this type of surgery is debated. The aim of this review was to assess the impact of sarcopenia on the risk of POPF. A literature search was performed using the PubMed database and the reference lists of relevant articles to identify papers about the impact of sarcopenia on POPF in pancreatic surgery. Twenty-one studies published between 2016 and 2021 with a total of 4068 patients were included. Some studies observed a significant difference in the incidence of POPF between the sarcopenic and non-sarcopenic patients undergoing pancreatoduodenectomy. Interestingly, there was a trend of a lower POPF rate in sarcopenic patients than in non-sarcopenic patients. Only one study included patients undergoing distal pancreatectomy specifically. The role of sarcopenia in surgical outcomes is still unclear. A combination of objective CT measurements could be used to predict POPF. It could be assessed by routine preoperative staging CT and could improve preoperative risk stratification in patients undergoing pancreatic surgery.

Abstract
OBJECTIVES Surgical treatment is an important option for inducing remission in Crohn's disease (CD); indeed, the longer the disease duration, the higher the cumulative surgical rate. Previous studies have shown that the pathogenesis of Crohn's disease is associated with sarcopenia, a condition of reduced skeletal muscle mass. Here, we investigated the effect of preoperative sarcopenia on postoperative disease activity. METHODS This retrospective study included 56 patients with CD with medical records who met our inclusion criteria. Sarcopenia was diagnosed based on the psoas muscle mass index derived from computed tomography images, with predetermined cutoff values of <6.36 cm2/m2 for men and <3.92 cm2/m2 for women. We performed univariate and multivariate analyses to identify factors associated with sarcopenia. RESULTS Of the 56 participants, nine (16%) had sarcopenia. The rate of preoperative treatment with biological drugs was significantly lower in the sarcopenia group than the non-sarcopenia group. In addition, the operation time was significantly longer, and hemorrhage occurred more often, in the sarcopenia group than in the non-sarcopenia group. Postoperatively, the CD activity index at 6 mo had significantly decreased in the non-sarcopenia group (P = 0.01) but not in the sarcopenia group (P = 0.20). Univariate and multivariate analyses showed that a low total serum protein level was significantly associated with sarcopenia. CONCLUSION Our results suggest that to maximize the effect of surgical treatment for CD, an appropriate nutritional intervention should be performed before surgery, or surgery should be postponed until after the patient recovers from sarcopenia.

Abstract
There are a variety of definitions and criteria used in clinical practice to define frailty. In the absence of a gold-standard definition, frailty has been operationally defined as meeting 3 out of 5 phenotypic criteria indicating compromised function: low grip strength, low energy, slowed walking speed, low physical activity, and unintentional weight loss. Frailty is a common problem in solid organ transplant candidates who are in the process of being listed for a transplant, as well as after transplantation. Patients with diabetes or chronic kidney disease (CKD) are known to be at increased risk of being frail. As pancreas transplantation is exclusively performed among patients with diabetes and the majority of them also have CKD, pancreas transplant candidates and recipients are at high risk of being frail. Sarcopenia, fatigue, low walking speed, low physical activity, and unintentional weight loss, which are some of the phenotypes of frailty, are very prevalent in this population. In various solid organs, frail patients are less likely to be listed or transplanted and have high waitlist mortality. Even after a transplant, they have increased risk of prolonged hospitalization, readmission, and delayed graft function. Given the negative impact of frailty on solid organ transplants, we believe that frailty would have a similar or even worse impact on pancreas transplantation. Due to the paucity of data specifically among pancreas transplant recipients, here we include frailty data from patients with CKD, diabetes, and various solid organ transplant recipients.

Abstract
BACKGROUND The diagnosis of sarcopenia emphasizes both, the quantity and quality of skeletal muscle. However, the impact of the combination of muscle quantity and quality on long-term survival remains unclear. This study aimed to assess the impact of the combination of skeletal muscle quantity and quality on long-term outcomes in patients with gastric cancer who underwent curative resection. METHODS We retrospectively assessed 242 patients aged ≥ 65 ears who underwent curative gastrectomy between 2006 and 2015. The psoas muscle mass index (PMI) and intramuscular adipose tissue content (IMAC) were measured on preoperative computed tomography as skeletal muscle quantity and quality, respectively. The sarcopenia stage was classified by the combination of preoperative skeletal muscle quantity and quality (non-sarcopenia, sarcopenia, and severe sarcopenia). Prognostic factors for the 5-year overall survival (OS), non-cancer-specific survival (non-CSS), and cancer-specific survival (CSS) were evaluated by multivariable Cox regression. RESULTS The median follow-up period was 63.2 months. The non-sarcopenia, sarcopenia, and severe sarcopenia groups comprised 88, 121, and 33 patients (36.4%, 50.0%, and 13.6%), respectively. The severe sarcopenia group was older, and had a greater depth of invasion, than the non-sarcopenia group. Multivariable analysis revealed severe sarcopenia as an independent predictive indicator of OS (hazard ratio [HR] 4.01; 95% confidence interval [CI] 1.75 to 9.22) and non-CSS (HR 3.27; 95% CI 1.61 to 6.67), but not CSS. CONCLUSIONS The combination of preoperative skeletal muscle quantity and quality was useful for predicting survival, especially death from other diseases, in elderly patients who underwent gastrectomy for gastric cancer.

Quantity and Quality of Skeletal Muscle as an Important Predictor of Clinical Outcomes in Patients with Esophageal Cancer Undergoing Esophagectomy after Neoadjuvant Chemotherapy. Ann Surg Oncol 2021; 28:7185-7195. [PMID: 33876359 DOI: 10.1245/s10434-021-10025-x] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2020] [Accepted: 03/27/2021] [Indexed: 12/21/2022]
Abstract
BACKGROUND Sarcopenia was previously linked to clinical outcomes for several cancer types, including esophageal cancer (EC), but most studies only measured the quantity of skeletal muscle mass. We aim to assess the clinical significance of evaluating the quantity and quality of skeletal muscle in patients with EC who underwent neoadjuvant chemotherapy (NAC) followed by esophagectomy. METHODS We included 333 consecutive patients with EC who underwent NAC followed by esophagectomy. The psoas muscle index (PMI) and intracellular muscle adipose tissue content (IMAC) were measured by computed tomography. We defined low PMI combined with high IMAC as severe sarcopenia, and assessed its impact on clinical outcomes. RESULTS Thirty-seven patients (11.1%) had severe sarcopenia. Compared with patients without severe sarcopenia, those with severe sarcopenia showed a significantly worse NAC response rate (54.1% vs 74.7%; P = 0.008), worse pathological response rate (24.3% vs 40.2%, P = 0.061), higher morbidity rate (67.6% vs 38.5%; P = 0.001), particularly for pneumonia (32.4% vs 14.9% P = 0.007) and expectoration disorder (37.8% vs 13.5% P < 0.001), and unfavorable survival (3-year overall survival rate: 54.1% vs 66.6% P = 0.027). Multivariable analysis of overall survival showed that severe sarcopenia (HR 1.68, P = 0.025) and cT (HR 1.52, P = 0.032) were independent prognostic factors of poor outcome. CONCLUSIONS PMI combined with IMAC represents a new criterion for sarcopenia that might be useful for predicting NAC response, postoperative complications, and long-term survival in patients with EC undergoing multidisciplinary treatments.

Recipient age and outcomes following simultaneous pancreas-kidney transplantation in the new millennium: Single-center experience and review of the literature. Clin Transplant 2021; 35:e14302. [PMID: 33783874 DOI: 10.1111/ctr.14302] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 03/23/2021] [Accepted: 03/24/2021] [Indexed: 12/30/2022]
Abstract
The influence of recipient age on outcomes following simultaneous pancreas-kidney transplantation (SPKT) in the modern era is uncertain. METHODS We retrospectively studied 255 patients undergoing SPKT from 11/01 to 8/20. Recipients were stratified according to age group: age <30 years (n = 16); age 30-39 years (n = 91); age 40-49 years (n = 86) and age ≥50 years (n = 62 [24.3%], including 9 patients ≥60 years of age). RESULTS Three-month and one-year outcomes were comparable. The eight-year patient survival rate was lowest in the oldest age group (47.6% vs 78% in the 3 younger groups combined, p < .001). However, eight-year kidney and pancreas graft survival rates were comparable in the youngest and oldest age groups combined (36.5% and 32.7%, respectively), but inferior to those in the middle 2 groups combined (62% and 50%, respectively, both p < .05). Death-censored kidney and pancreas graft survival rates increased from youngest to oldest recipient age category because of a higher incidence of death with functioning grafts (22.6% in oldest group compared to 8.3% in the 3 younger groups combined, p = .005). CONCLUSIONS Recipient age did not appear to significantly influence early outcomes following SPKT. Late outcomes are similar in younger and older recipients, but inferior to the middle 2 age groups.

Abstract
Background. The impact of functional status on survival among simultaneous pancreas-kidney transplant (SPKT) candidates and recipients is not well described. Methods. We examined national Scientific Registry of Transplant Recipients (SRTR) data for patients listed for SPKT in the United States (2006–2019). Functional status was categorized by center-reported Karnofsky Performance Score (KPS). We used Cox regression to quantify associations of KPS at listing and transplant with subsequent patient survival, adjusted for baseline patient and transplant factors (adjusted hazard ratio, 95% LCLaHR95%UCL). We also explored time-dependent associations of SPKT with survival risk after listing compared with continued waiting in each functional status group. Results. KPS distributions among candidates (N = 16 822) and recipients (N = 10 316), respectively, were normal (KPS 80–100), 62.0% and 57.8%; capable of self-care (KPS 70), 23.5% and 24.7%; requires assistance (KPS 50–60), 12.4% and 14.2%; and disabled (KPS 10–40), 2.1% and 3.3%. There was a graded increase in mortality after listing and after transplant with lower functional levels. Compared with normal functioning, mortality after SPKT rose progressively for patients capable of self-care (aHR, 1.001.181.41), requiring assistance (aHR, 1.061.311.60), and disabled (aHR, 1.101.552.19). In time-dependent regression, compared with waiting, SPKT was associated with 2-fold mortality risk within 30 days of transplant. However, beyond 30 days, SPKT was associated with reduced mortality, from 52% for disabled patients (aHR, 0.260.480.88) to 70% for patients with normal functioning (aHR, 0.260.300.34). Conclusions. While lower functional status is associated with increased mortality risk among SPKT candidates and recipients, SPKT can provide long-term survival benefit across functional status levels in those selected for transplant.

Abstract
OBJECTIVES Our aim was to investigate effects of surgery on living donors' body composition and clarify factors related to it. MATERIALS AND METHODS We evaluated preoperative computed tomography images of 335 living kidney donors (127 men, 209 women) to calculate 3 body composition parameters and changes with aging by sex: (1) skeletal muscle mass, quantified by skeletal muscle index; (2) fat distribution, calculated by visceral adipose tissue/subcutaneous adipose tissue ratio; and (3) muscle quality, quantified by intramuscular adipose tissue content. Thereafter, with pre- and postoperative computed tomography images from 75 living kidney donors (25 men, 50 women) after hand-assisted laparoscopic donor nephrectomy, we compared pre- and postoperative body composition changes. RESULTS Annual change in intramuscular adipose tissue content with age was 0.0049 in men and 0.0091 in women. Of 75 patients, 49 had lower quality of muscle, intramuscular adipose tissue content was significantly higher after nephrectomy (P < .001), and median change in intramuscular adipose tissue content was 0.061 (range, 0.018-0.11) in men and 0.052 (range, 0.017-0.18) in women. Univariate analysis revealed that skeletal mass index and visceral adipose tissue/subcutaneous adipose tissue ratio changes were significantly different between the intramuscular adipose tissue content improvement and deterioration groups. Multivariate analysis revealed skeletal mass index change was an independent factor for intramuscular adipose tissue content change (P = .0019). Intramuscular adipose tissue content change was negatively correlated with skeletal mass index change (r = -0.40). CONCLUSIONS Although muscle quality deteriorates after nephrectomy, maintaining muscle mass is important to retaining muscle quality.

Preoperative Assessment of Muscle Mass Using Computerized Tomography Scans to Predict Outcomes Following Orthotopic Liver Transplantation. Transplantation 2020; 103:2506-2514.

Abstract
BACKGROUND Sarcopenia is an established risk factor predicting survival in chronically ill and trauma patients. We herein examine the assessment and clinical implication of sarcopenia in liver transplantation (LT). METHODS Computerized tomography scans from 172 patients waitlisted for LT were analyzed by applying 6 morphometric muscle scores, including 2 density indices (psoas density [PD] and skeletal muscle density [SMD]) and 4 scores based on muscle area (total psoas area, psoas muscle index, skeletal muscle area, and skeletal muscle index). RESULTS The prevalence of sarcopenia in our cohort ranged from 7.0% to 37.8%, depending on the score applied. Only sarcopenia as defined by the density indices PD and SMD (but not total psoas area, psoas muscle index, skeletal muscle area, or skeletal muscle index) revealed clinical relevance since it correlates significantly with postoperative complications (≥Grade III, Clavien-Dindo classification) and sepsis. Furthermore, sarcopenia predicted inferior patient and graft survival, with low muscle density (PD: <38.5 HU or SMD: <30 HU) representing an independent risk factor in a multivariate regression model (P < 0.05). Importantly, the widely used Eurotransplant donor risk index had a predictive value in nonsarcopenic patients but failed to predict graft survival in patients with sarcopenia. CONCLUSIONS Sarcopenia revealed by low muscle density correlates with major complications following LT and acts as an independent predictor for patient and graft survival. Therefore, the application of a simple computerized tomography-morphologic index can refine an individual recipient's risk estimate in a personalized approach to transplantation.

Abstract
Post-operative morbidity of pancreatectomies occurs in up to 40-50% of patients, even in modern series. There is a need to find a simple scale in order to identify patients with increased risk of developing major post-operative complications after pancreatic resections. Many studies have been published on sarcopenia and surgical outcomes. Aspects of sarcopenia are presented, along with a systematic review using PRISMA guidelines, in order to search for articles about sarcopenia and pancreatic surgery. The impact of sarcopenia on morbidity and mortality in pancreatic resections is still unclear. The studies presented have been carried out over long periods of time, and many of them compare patients with different diseases. There are also different definitions of sarcopenia, and this can influence the results, as some of the reviewed articles have already shown. It is necessary to unify criteria, both in the definition and in the cut-off values. Prospective studies and consensus on sarcopenia diagnosis should be achieved.
