Effects of sarcopenia and nutritional status on surgical outcomes for metastatic spinal tumors: In the perspective of peri-operative complications and performance improvement.

With the advancement of cancer treatment, appropriate treatment for musculoskeletal problems is becoming more important as it extends the patient's lifespan and improves the quality of life. In surgical treatment for metastatic spine tumors (MST), various efforts are being considered to obtain a good prognosis. The purposes of this study are to analyze prognostic factors for postoperative ambulation and perioperative complications in patients surgically treated for MST with neurologic symptoms. Seventy five cases of patients who underwent surgery for MST with neurologic symptoms were enrolled between December 2016 and January 2023. Postoperative ambulatory function and medical complications were assessed for each patient in this study. The endpoint of ambulatory function was defined as the best function among entire periods of follow-up outpatient visits. We defined the improvement of ambulatory function as improvement in Eastern Cooperative Oncology Group (ECOG) scale. For complications, we applied complication classification system for orthopaedic surgery. Perioperative complications were defined as those requiring changes of treatment compared with routine postoperative treatment during patient's admission. Confirmed complications included expire, delirium, urinary tract infection (UTI), pneumonia, sepsis, bacteremia, acute kidney injury (AKI), chylothorax. Prognostic factors were collected and analyzed for relationship by logistic regression. Of the 75 cases, postoperatively 42 (56%) cases of patients were improved in Nurick grade, 36 (48%) cases of patients in ECOG performance. And 21 (28%) cases of patients were treated in intensive care unit (ICU) and 15 (20%) cases of patients suffered from major perioperative complications. Regression analysis showed that clinical factors such as ECOG, psoas muscle index (PMI) and prognostic nutritional index (PNI) were related to the improvement of ambulatory function and incidence of perioperative complications. On multivariate analysis, improvement of ambulatory function was associated with PMI (p = 0.014) and incidence of perioperative complications was associated with PNI (p = 0.045). Preoperative nutritional status and sarcopenia are related factors in the outcome of surgical treatment for MST, and preoperative efforts to improve these may be a way to obtain better clinical results.

The Effects of Sarcopenia and Fracture Risk on Kinesiophobia, Fear of Falling, Fall Risk and Quality of Life in Geriatric Individuals

Impact of Possible Sarcopenia and Nutritional Status on Postoperative Quick Disabilities of the Arm, Shoulder, and Hand Score in Geriatric Women With Distal Radius Fracture

Distal radius fracture (DRF), sarcopenia, and malnutrition have been reported to be interrelated. However, there are few reports on the effects of sarcopenia and malnutrition on DRF patients' postoperative outcomes. This study examined the healthy-side grip strength and preoperative blood tests to determine the presence of possible sarcopenia (PS) and malnutrition in geriatric women with DRF and their impact on postoperative functional outcomes. Fifty-five woman older than 60 years treated with volar-locking plate fixation for low-energy DRF from standing-level falls were retrospectively studied. Based on the criteria of The Asian Working Group for Sarcopenia 2019, patients with a healthy-side grip strength <18 kg were defined as PS. Nutritional assessment was performed using Onodera's Prognostic Nutritional Index (PNI) before surgery, with a value <50 defined as malnutrition. The Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) was used for functional assessment at 1 year after surgery. Patients were divided into two groups according to PS, and patient demographic data and postoperative outcomes were compared. Multiple regression analysis was performed to estimate the regression coefficient and 95% confidence intervals for 1-year QuickDASH after surgery with adjustment for age, PS, and malnutrition. Possible sarcopenia was present in 10 patients (18.2%), and malnutrition in 24 patients (43.6%). Possible sarcopenia patients were older, had lower PNI, serum albumin, and both sides grip strength, and worse QuickDASH compared with non-PS patients. In multiple regression analysis, age, PS, and malnutrition were significant predictors of QuickDASH (standardized coefficient β, 0.35, 0.34, and 0.24; 95% confidence interval, 0.22-1.02, 3.52-16.49, and 0.50-10.78). Possible sarcopenia with a healthy-side grip strength <18 kg and malnutrition with a PNI <50 were associated with worse 1-year QuickDASH after surgery in women DRF patients over 60 years. Prognostic Ⅳ.

Effects of sarcopenia on changes in prevalence of patients with depressive mood during hospitalization in geriatric rehabilitation.

The effect of sarcopenia on depressive mood during geriatric rehabilitation remains unclear. This study investigated the potential influence of sarcopenia on depressive mood among geriatric patients in a rehabilitation setting. This observational cohort study enrolled 204 patients aged ≥65 years (mean: 78.8±7.6 years, 45.1% women) admitted to a rehabilitation unit between April 2020 and July 2021. Sarcopenia was diagnosed based on the Asian Working Group for Sarcopenia: 2019 Consensus Update on Sarcopenia Diagnosis and Treatment (AWGS2019) criteria, which include low handgrip strength and muscle mass. Depressive mood was defined as a 15-item Geriatric Depression Scale score of ≥6 points. We applied logistic regression models to examine the influence of sarcopenia on depressive mood at discharge. We observed sarcopenia in 58.3% of patients. The logistic regression model showed that sarcopenia negatively influenced depressive mood at discharge (odds ratio, 5.460; 95% confidence interval, 2.344-13.415). Of the 68 patients without depressive mood at admission, those with sarcopenia (n=31) had a significantly higher incidence of depressive mood at discharge compared with patients without sarcopenia (n=37) (41.9% vs. 16.2%, p=0.037). Sarcopenia at admission negatively affected depressive mood at discharge from geriatric rehabilitation. Thus, early and routine assessment of sarcopenia is vital for patients undergoing geriatric rehabilitation.

The prevalence and effects of sarcopenia in patients with metabolic dysfunction-associated steatotic liver disease (MASLD): A systematic review and meta-analysis

Background and AimsSarcopenia is a common complication in patients with metabolic dysfunction- associated steatotic liver disease (MASLD). However, the prevalence and its impact on the survival of sarcopenia in patients with MASLD is unknown. In this study, we aimed to assess the prevalence and effects of sarcopenia in patients with MASLD. MethodsSystematic review and meta-analysis of full texts of relevant studies were searched from inception until June 12, 2024 in five databases (PubMed, Cochrane Library, Embase, Web of Science, and the China National Knowledge Infrastructure). Next, we assessed the prevalence of sarcopenia in MASLD, and calculated the ORs and HRs between sarcopenia and MASLD based on the adjusted data from individual studies. Statistical analyses were performed using Stata 11.0. ResultsOf the 2,984 records considered, 29 studies recruiting 63,330 patients were included. The pooled prevalence of sarcopenia in patients with MASLD was 23.5% overall (95% CI; 19.1%-27.9%, I2 = 99.6%), and was higher in Asian patients, male, cross-sectional studies, when BIA were employed to measure muscle mass, one criterion of diagnosis sarcopenia, MASLD was diagnosed employing MRI, and moderate-quality studies. Sarcopenia was associated with MASLD patients (adjusted odds ratio [aOR] 2.08, 95% CI 1.58-2.74, I2 = 93.6%) with similar findings in subgroups stratified by age, study design, methods for measuring muscle mass, assessment method to detect sarcopenia, and study quality. The association between all-cause mortality further supports the association between sarcopenia and poor prognosis with MASLD (aHR 1.59, 95% CI 1.33-1.91, I2 =0%). ConclusionsSarcopenia was strongly associated with MASLD progression and was a risk factor not only for MASLD pathogenesis but was also markedly correlated with MASLD-associated mortality.

Sarcopenia adversely impacts clinical outcomes in patients undergoing pancreaticoduodenectomy: A systematic review and meta-analysis.

Sarcopenia is a syndrome marked by a gradual and widespread reduction in skeletal muscle mass and strength, as well as a decline in functional ability, which is associated with malnutrition, hormonal changes, chronic inflammation, disturbance of intestinal flora, and exercise quality. Pancreatoduodenectomy is a commonly employed clinical intervention for conditions such as pancreatic head cancer, ampulla of Vater cancer, and cholangiocarcinoma, among others, with a notably high rate of postoperative complications. Sarcopenia is frequent in patients undergoing pancreatoduodenectomy. However, data regarding the effects of sarcopenia in patients undergoing pancreaticoduodenectomy (PD) are both limited and inconsistent. To assess the influence of sarcopenia on outcomes in patients undergoing PD. The PubMed, Cochrane Library, Web of Science, and Embase databases were screened for studies published from the time of database inception to June 2023 that described the effects of sarcopenia on the outcomes and complications of PD. Two researchers independently assessed the quality of the data extracted from the studies that met the inclusion criteria. Meta-analysis using RevMan 5.3.5 and Stata 14.0 software was conducted. Forest and funnel plots were used, respectively, to demonstrate the outcomes of the sarcopenia group vs the non-sarcopenia group after PD and to evaluate potential publication bias. Sixteen studies encompassing 2381 patients were included in the meta-analysis. The patients in the sarcopenia group (n = 833) had higher overall postoperative complication rates [odds ratio (OR) = 3.42, 95% confidence interval (CI): 1.95-5.99, P < 0.0001], higher Clavien-Dindo class ≥ III major complication rates (OR = 1.41, 95%CI: 1.04-1.90, P = 0.03), higher bacteremia rates (OR = 4.46, 95%CI: 1.42-13.98, P = 0.01), higher pneumonia rates (OR = 2.10, 95%CI: 1.34-3.27, P = 0.001), higher pancreatic fistula rates (OR = 1.42, 95%CI: 1.12-1.79, P = 0.003), longer hospital stays (OR = 2.86, 95%CI: 0.44-5.28, P = 0.02), higher mortality rates (OR = 3.17, 95%CI: 1.55-6.50, P = 0.002), and worse overall survival (hazard ratio = 2.81, 95%CI: 1.45-5.45, P = 0.002) than those in the non-sarcopenia group (n = 1548). However, no significant inter-group differences were observed regarding wound infections, urinary tract infections, biliary fistulas, or postoperative digestive bleeding. Sarcopenia is a common comorbidity in patients undergoing PD. Patients with preoperative sarcopenia have increased rates of complications and mortality, in addition to a poorer overall survival rate and longer hospital stays after PD.

TO STUDY THE PREVALENCE OF SARCOPENIA IN TYPE-2 DIABETIC PATIENTS IN A RURAL TERTIARY CARE HOSPITAL

Objective: The objective of this study was to study the prevalence of sarcopenia in type-2 diabetic population coming to a rural tertiary care hospital. Methods: A cross-sectional study involving 150 participants including both outpatient and inpatient department patients was conducted at MM Institute of Medical Sciences and Research, Mullana (Ambala) between June 2021 and June 2022 after seeking appropriate permissions and approval from the Institutional Ethics Committee. Patients who consented to participation were enrolled in the study and were evaluated as per the European working group for sarcopenia in older people algorithm using bioelectrical impedance analysis and were asked to fill out a printed proforma (available in Hindi and English languages) to assess their SARC-CalF scores, handgrip strength, calf circumference and comorbidities. Patients were interviewed if they were illiterate, and responses were recorded. Statistical analyses were performed on IBM SPSS Statistics version 26. Results: The overall prevalence of sarcopenia was found to be 3.3% in 150 subjects who were enrolled in the study. Among the cases (diabetics), the prevalence was 4.0% and 2.67% in the controls (non-diabetics). Mean handgrip strength was found to be 18.73 kg among cases and 19.47 kg among controls. Handgrip strength did not show a significant association with diabetes (p=0.435). Handgrip strength was not found to be significantly associated to sex. Mean gait speed (in m/s) was found to be 1.42 in a range of 0.30–2.50 with a standard deviation of 0.59. Mean gait speed was 1.87 m/s in controls and 0.96 m/s in cases. Gait speed was found to be significantly associated with diabetes (p=0.00). No significant association was seen with sex (p=0.95). Mean calf circumference was found to be 33.28 cm among cases and 34.49 cm in controls. Calf circumference was found to be significantly correlated with diabetes (p=0.00). The SARC-CalF questionnaire was shown to have a sensitivity of 40% and a specificity of 100% at the recommended threshold of ≥11. In the study group, the mean HbA1c was found to be 10.1%. Sarcopenia was not found to be significantly associated with diabetes (p=0.649). No statistically significant relationship was found between hypertension and sarcopenia (p=0.394). Conclusion: Sarcopenia is largely an overlooked disease, especially in India. Various efforts to study the prevalence, causation, and effects of sarcopenia have been made, but no large-scale studies have been undertaken so far. Our study concluded that the SARC-CalF questionnaire can be used as a bedside screening tool. Though our study failed to find any statistically significant relationship between sarcopenia and diabetes, large scale studies are still warranted in this regard.

Effects of sarcopenia and myosteatosis are alleviated in reduced port surgery for diverticulitis

PurposeMany studies report the predictive value of sarcopenia, myosteatosis, and visceral fat for clinical outcome after surgery. Radiological analysis of body composition is a valuable tool for identifying high-risk patients undergoing major abdominal surgery. Despite the high prevalence of diverticular disease, patients with benign conditions have hardly been studied in this context. This study aims to evaluate the impact of reduced port surgery on the outcome of patients with diverticulitis, adjusting for body composition.MethodsWe assessed body composition profiles using preoperative CT slices at the level of the third lumbar vertebra in consecutive patients undergoing single-port elective surgery for diverticulitis in a single center. The effects of sarcopenia, myosteatosis, and visceral fat on mortality and complications were analyzed and adjusted for age and gender.ResultsWe enrolled 99 patients with diverticulitis undergoing elective single port surgery in this study. Of the patients, 71.2% had sarcopenia and 60.6% had myosteatosis. The overall complication rate was 17.2%, and the rate of anastomotic leakage was 4.0%. Thirty-day mortality was 2.0%. Loss of skeletal muscle mass, myosteatosis, and visceral fat were not associated with higher complication or mortality rates in our cohort.ConclusionBody composition profiles had no impact on the clinical course in our cohort. Minimally invasive surgery may potentially compensate for the adverse effects of sarcopenia and myosteatosis in diverticulitis.

Effects of Sarcopenia on Post-Operative Complications in Patients Undergoing Gastrectomy for Gastric Cancer: An Integrative Review

The objective of this paper is to investigate the influence of sarcopenia on postoperative complications in patients undergoing gastrectomy for gastric cancer. PubMed, Cochrane, Science Direct and SciELO databases were used, with the search strategy: Sarcopenia and Stomach Neoplasms. The integrative review was structured with fifteen articles, published from 2015 to 2019. Data analysis was performed in a descriptive way. Twelve studies identified sarcopenia as a risk factor for postoperative complications in patients undergoing gastrectomy for gastric cancer. The reduction in skeletal muscle mass was associated with decreased intake or bioavailability of nutrients and metabolic changes, such as increased production of pro-inflammatory molecules resulting in weakening of the immune system and poor postsurgical healing. It was concluded that the presence of sarcopenia in these patients is related to a higher occurrence of postoperative complications.

Sarcopenic Obesity Is Associated With Reduced Cardiorespiratory Fitness Compared With Nonsarcopenic Obesity in Patients With Heart Failure With Reduced Ejection Fraction.

Sarcopenia impairs cardiorespiratory fitness (CRF) in patients with heart failure with reduced ejection fraction (HFrEF). Obesity has also been shown to impair CRF; however, the effects of sarcopenia on CRF in patients with obesity and HFrEF are unknown. The aim of this analysis was to examine differences in CRF between patients with sarcopenic obesity (SO) and non-SO (NSO) with HFrEF. We also assessed associations between skeletal muscle mass index (SMMI) and CRF. Forty patients with HFrEF and obesity underwent cardiopulmonary exercise testing to collect measures of CRF including peak oxygen consumption (VO2), circulatory power, oxygen uptake efficiency slope, O2 pulse, and exercise time. Body composition was performed in all patients using bioelectrical impedance analysis to quantify fat mass index and divide patients into SO and NSO based on SMMI cutoffs. Results are presented as mean (SD) or median [interquartile range] as appropriate. Nearly half (43% [n=17]) of patients had SO. Patients with SO had a lower SMMI than those with NSO, and no differences in fat mass index were observed between groups. Those with SO achieved a lower absolute peak VO2 (NSO, 1.62±0.53 L·min-1 versus SO, 1.27±0.44 L·min-1, P=0.035), oxygen uptake efficiency slope (NSO, 1.92±0.59 versus SO, 1.54±0.48, P=0.036), and exercise time (NSO, 549±198 seconds versus SO, 413±140 seconds, P=0.021) compared to those with NSO. On multivariate analysis, SMMI remained a significant predictor of absolute peak VO2 when adjusted for age, sex, adiposity, and HF severity. In patients with HFrEF and obesity, sarcopenia, defined as low SMMI, is associated with a clinically significant reduction in CRF, independent of adiposity.

Effects of Sarcopenia, Myosteatosis, and the Prognostic Nutritional Index on Survival in Stage 2 and 3 Gastric Cancer Patients

Background We aimed to evaluate the relationship between sarcopenia, myosteatosis, and systemic inflammatory response biomarkers and their prognostic role in stage 2 and 3 gastric cancer patients. Methods This study included 84 patients with stage 2 or 3 gastric cancer who underwent a gastrectomy. Computed tomography scans were used to determine the skeletal muscle index (SMI) at the third lumbar vertebra level for sarcopenia and myosteatosis. Results Based on the Asian Working Group of Sarcopenia (AWGS2019) criteria, the sarcopenia incidence was 36.9% and that of myosteatosis 46.4%. Univariate analysis showed that sarcopenia (48 vs. 14 mo, p < 0.001), myosteatosis (45 vs. 16 mo, p = 0.016), a low prognostic nutritional index (60 vs. 15 mo, p = 0.003), stage 3 (104 vs. 21 mo, p = 0.013), and old age (45 vs. 16 mo, p = 0.015) were poor prognostic markers. Multivariate analysis revealed that sarcopenia (AWGS2019), age, and stage significantly affected overall survival (hazard ratio: 3.31, 95% CI: 1.85–5.1; 1.96, 95% CI: 1.06–6.63; 2.5, 95% CI: 1.2–5.1, respectively). Conclusion We showed that sarcopenia directly affects overall gastric cancer survival.

Effects of sarcopenia and sarcopenic obesity on joint pain and degenerative osteoarthritis in postmenopausal women

This study aimed to identify the prevalence of sarcopenia, obesity, and sarcopenic obesity and examine their association with radiographic knee osteoarthritis (OA) and knee pain in Korean postmenopausal women. This cross-sectional study utilized the data from Korean National Health and Nutrition Examination Surveys 2009–2011. The participants were categorized into 4 groups based on body composition: either sarcopenic (appendicular skeletal muscle < 23%) or not, either obese (body mass index ≥ 25.0 kg/m2) or not. The prevalence of radiographic knee OA and knee pain was calculated. The effect of hormone replacement therapy (HRT) was also evaluated. The prevalence of radiographic knee OA, knee pain, and both were all highest in the sarcopenic obese group and lowest in the control group (61.49% vs. 41.54%, 39.11% vs. 27.55%, 32.04% vs. 17.82%, all p < 0.001). Without sarcopenia, obese women showed significantly higher ratio of radiographic knee OA only (57.64% vs. 41.54%, p < 0.001). With sarcopenia, the coexistence of obesity presented higher ratio of radiographic knee OA, knee pain, and both compared to sarcopenia without obesity (61.49% vs. 41.82%, 39.11% vs. 27.61%, 32.04% vs. 17.60%, all p < 0.001). The use of HRT for more than 1 year was not associated with radiographic knee OA, knee pain, or both (p = 0.147, 0.689 and 0.649, respectively). Obesity with sarcopenia had greater effect on knee OA compared to obesity without sarcopenia. Moreover, HRT use for more than 1 year was not associated with the prevalence of knee OA. Therefore, more efforts should focus on reducing body fat and increasing muscle in postmenopausal women with knee OA.

Physical activity for chronic pancreatitis: a systematic review.

Chronic pancreatitis (CP) is a progressive inflammatory disorder of the pancreas. Sarcopenia is a degenerative loss of skeletal muscle mass, quality, and strength and is commonly associated with chronic pancreatitis. Regular physical activity and adequate functional fitness have been found to ameliorate the risk and effects of sarcopenia in other chronic diseases. The objective of this systematic review was to collate all the published evidence which has examined any type of physical activity as an intervention in the chronic pancreatitis patient population. This systematic review was conducted in accordance with the PRISMA guidelines. The search strategy was designed by the medical librarian (DM) for Embase and then modified for the other search platforms. Two of the researchers (BM) and (AM) then performed the literature search using the databases Embase, Medline, CINAHL, and Web of Science. An electronic identified a total of 571 references imported to Covidence as 420 when the duplicates (151) were removed. 420 titles were screened and 390 were removed as not relevant from their titles. 30 full text papers were selected and from these, only one full text paper was deemed suitable for inclusion. There is currently insufficient evidence to advise physical activity in the chronic pancreatitis population. However, given the evidence to support physical activity in many other chronic diseases this review highlights the need for urgent investigation of physical activity as an intervention on this specific patient population.

Association between sarcopenia and cognitive impairment in the older people: a meta-analysis

The effects of sarcopenia on the older people are profound, increasing the risk of adverse outcomes for older patients. Although the substantial impact of sarcopenia on maintaining functional independence and adverse health outcomes has been described many times in the past, the link between sarcopenia and cognitive impairment in older adults remains lacking in evidence and controversial. Therefore, we conducted a comprehensive search of available national and international databases and carried out a meta-analysis to examine the association between sarcopenia in older people and cognitive impairment. Relevant experiments had been recognized via looking out electronic databases and conference sessions.The present study included case-control, cohort, or cross-sectional studies of the association between sarcopenia and cognitive impairment in the older people. The meta-analysis included 26 articles and 18,788 participants were involved after assessment of eligibility. The results of this meta-analysis showed that the risk of developing cognitive impairment was significantly higher in patients with sarcopenia than in those without sarcopenia [OR = 1.75; 95%CI = 1.57, 1.95; P < 0.00001], MMSE score of sarcopenia group was lower than that of non-sarcopenia group, the difference was statistically significant [OR = -2.23; 95% CI = -2.48, -1.99; P < 0.00001]. Overall, this meta-analysis showed an association between sarcopenia and cognitive impairment in the older people, demonstrating a significant association between sarcopenia and cognitive impairment. This suggested that providing comprehensive sarcopenia screening and active prevention for the older people with cognitive decline has certain clinical value for improving the quality of life of the older people.

Effects of Sarcopenia on Postoperative Outcomes in Patients Who Underwent Gastrectomy for Gastric Cancer.

The relationship between sarcopenia and postoperative outcomes in patients with gastric cancer remains controversial. This study aimed to investigate the impact of sarcopenia on short-term outcomes after surgery for gastric cancer. Patients who underwent surgical treatment for gastric cancer were evaluated in this prospective observational study. Muscle strength, muscle mass, and physical performance were measured before surgery. Diagnosis of sarcopenia was based on the revised European Working Group on Sarcopenia criteria. Postoperative 30-day outcomes, including complications, reoperation, readmission, and operative mortality, were recorded. Sarcopenia was observed in 31 out of 146 patients (21.2%). The overall complication incidence was 31.5%. The postoperative complication rate was higher in the sarcopenic patients compared to the nonsarcopenic patients (54.8% versus 25.2%, P=0.003). There was no statistically significant difference in terms of surgical complication rates (25.8% versus 14.8%, P=0.239), although the sarcopenic group had a significantly higher systemic complication rate (38.7% versus 13%, P=0.003). No statistically significant difference was observed in terms of major complications (3.2% versus 5.2%, P=1.000). Muscle strength, muscle mass, and physical performance were not identified as independent factors when tested alone at adjusted multivariable analysis. Sarcopenia (Odds ratio: 2.73, 95% CI 1.02-7.52, P=0.047) and severe sarcopenia (Odds ratio: 4.44, 95% CI 1.57-13.34, P=0.006) were identified as independent prognostic factors for postoperative complications. Sarcopenia was associated with postoperative complications after gastrectomy for gastric cancer. Severe sarcopenia may serve as a more robust prognostic indicator. The variation in the complication rates between sarcopenic and nonsarcopenic patients was mainly due to difference in systemic complications rather than surgical complications.

199P Advanced breast cancer patient involvement in the evaluation of an available online exercise program for use in a future clinical trial

In advanced breast cancer (ABC) muscular resistance exercise can improve fatigue (European Society of Medical Oncology guidelines) and effects of sarcopenia; the latter associated with poor outcome. To date, clinical trials examining exercise in this setting have reported poor adherence, compromising ability to complete the trial accrual. In order to evaluate the use of an online platform to deliver an exercise intervention, we used a platform (PHYSIOTEC) to demonstrate a range of exercises, involving patients early to seek their evaluation and feedback of utilizing such a platform.

Quality of Life and Functionality of Head and Neck Cancer Patients Are Diminished As a Function of Sarcopenia and Obesity.

Health-related quality of life (QoL) is a measure that allows us to know the patient's perception of well-being and how it is affected by their disease and treatments. In cancer patients, sarcopenia has been associated with low scores on various instruments used to assess the QoL; however, little information is available on the effects of sarcopenia and sarcopenic obesity on the QoL of patients with head and neck cancer (H&NC). In this cross-sectional study with 71 H&NC patients aged between 40 and 80 years, we describe the scores on the instruments EORTC QLQ C-30 and EORTC QLQ-H&N35 according to the sarcopenia phenotype (NSG, nonsarcopenic group; SG, sarcopenic group; and SOG, sarcopenic obesity group), hand-grip strength, gait speed, total lymphocyte count, albumin, cholesterol and C-reactive protein, and the relationships between these variables. The prevalence of sarcopenia and sarcopenic obesity was 48% and 28%, respectively. The QoL analysis showed that NSG had higher scores on the physical functioning scale [NSG 93 (83-100); SG 73 (52-88); SOG 83 (53-93), P = .009] and lower scores on the fatigue scale [NSG 11 (0-22); S 39 (30-67); SOG 44 (14-56); P = .004]. The NSG had a higher hand-grip strength (31.1kg) than SG (24.1kg, P = .007) and SOG (26.3kg, P = .001), and a lower C-reactive protein. The SG and SOG showed no differences between them. Patients with sarcopenia or sarcopenic obesity have lower physical performance and a higher level of fatigue than nonsarcopenic patients. This loss of function can maintain or worsen sarcopenia due to the patient's self-restraint in physical exertion that encourages an increase in muscle tissue.

Sarcopenia and risk of infection in adult heart transplant recipients in Japan.

AimsHeart transplantation (HT) is an effective therapeutic option for end‐stage heart failure. Infection is a major cause of morbidity and mortality after HT. Sarcopenia, defined as the loss of muscle mass and strength, is a common comorbidity in HT candidates with end‐stage heart failure. However, the effects of sarcopenia on the occurrence of post‐HT infections are not well understood. Therefore, we explored the association between the skeletal muscle mass and post‐transplant infections in adult HT recipients.Methods and resultsWe retrospectively examined the records of 135 patients who underwent HT between August 2007 and November 2019 at our institution. Pre‐transplant computed tomography was used to calculate the skeletal muscle index (SMI) at the level of the third lumbar vertebra. Muscle wasting was defined as the SMI of the lowest sex‐based tertiles. The primary endpoint was infections within 6 months of HT. The study included 109 patients (80 men, mean age: 41.6 ± 12.0 years): 37 patients in the muscle wasting group and 72 patients in the non‐muscle wasting group. The mean SMI values in the muscle wasting and non‐muscle wasting groups were 29.9 ± 4.8 cm2/m2 and 40.7 ± 6.7 cm2/m2, respectively. Prior to HT, 108 (99.1%) patients were on left ventricular assist device support, and during that support, the rate of late right heart failure was significantly higher in the muscle wasting group than non‐muscle wasting group (P = 0.012). Sixteen infections occurred within 6 months of HT. The most common infection sites included the respiratory tract (n = 5) and the upper gastrointestinal tract (n = 5), followed by the urinary tract (n = 4). Overall, 10 patients experienced infections in the muscle wasting group (27.0%) and 6 in the non‐muscle wasting group (8.3%) (P = 0.009). Two patients in the muscle wasting group required intensive care unit admission, compared to none in the non‐muscle wasting group. Low skeletal muscle mass was associated with infections in the univariate and multivariate logistic regression models (hazard ratio: 3.68, 95% confidence interval: 1.19–11.3; P = 0.023). However, the duration of all‐cause mortality within 3 years did not differ between the groups (P = 0.56).ConclusionsLow skeletal muscle mass is a predictor of post‐HT infections within 6 months of HT.

Sarcopenia and Ghrelin System in the Clinical Outcome and Prognosis of Gastroenteropancreatic Neuroendocrine Neoplasms.

Simple SummaryMalnutrition and sarcopenia affect clinical outcomes in cancer patients. Nutritional evaluation in patients with neuroendocrine neoplasms (NENs) is not routinely performed. Currently, the evaluation of sarcopenia using CT scans is the gold standard in cancer patients, additionally, anthropometric, biochemical and molecular analysis of patients with gastroenteropancreatic NENs at diagnosis was perfomed. The expression levels of key ghrelin system components were assessed in 63 tumor samples. Results: Nutritional parameters were similar in GEP-NEN tumors of different origin. Relapsed disease was associated with decreased BMI. Patients who presented with weight loss at diagnosis had significantly lower overall survival (108 (25–302) vs. 263 (79–136) months). Ghrelin O-acyltransferase (GOAT) enzyme expression was higher in these patients. The prevalence of sarcopenia using CT images reached 87.2%. Mortality was observed only in patients with sarcopenia. Muscle evaluation was correlated with biochemical parameters but not with the expression of ghrelin system components. Conclusion: Survival is related to the nutritional status of patients with GEP-NENs and also to the molecular expression of some relevant ghrelin system components. Routine nutritional evaluation should be performed in these patients, in order to prescribe appropriate nutritional support, when necessary, for increasing quality of life and improving clinical outcomes.Background: Malnutrition and sarcopenia affect clinical outcomes and treatment response in cancer patients. Patients with neuroendocrine neoplasms (NENs) may present with additional symptoms related to tumor localization in the gastrointestinal tract and hormone secretion, increasing the risk and effects of sarcopenia. Aim: To explore the presence of malnutrition and sarcopenia in gastroenteropancreatic (GEP)-NEN patients, their relation to tumor characteristics, patient outcomes, survival and the molecular expression of ghrelin system components in the tumor. Patients and methods: One-hundred-and-four patients were included. Anthropometric, biochemical and CT-scans at diagnosis were evaluated. The expression levels of key ghrelin system components were assessed in 63 tumor samples. Results: Nutritional parameters were similar in GEP-NEN tumors of different origin. Relapsed disease was associated with decreased BMI. Patients who presented with weight loss at diagnosis had significantly lower overall survival (108 (25–302) vs. 263 (79–136) months). Ghrelin O-acyltransferase (GOAT) enzyme expression was higher in these patients. The prevalence of sarcopenia using CT images reached 87.2%. Mortality was observed only in patients with sarcopenia. Muscle evaluation was correlated with biochemical parameters but not with the expression of ghrelin system components. Conclusion: Survival is related to the nutritional status of patients with GEP-NENs and also to the molecular expression of some relevant ghrelin system components. Routine nutritional evaluation should be performed in these patients, in order to prescribe appropriate nutritional support, when necessary, for increasing quality of life and improving clinical outcomes.

A Novel Technique for Radiographic Diagnosis of Sarcopenia that Accurately Predicts Postoperative Complications in Lower Extremity Free Flap Patients.

Sarcopenia is linked to poor outcomes throughout the surgical literature and can be assessed on preoperative imaging to potentially aid in risk stratification. This study examined the effects of sarcopenia on surgical morbidity following lower extremity (LE) reconstruction, and also compared two methods of assessment, one of which is novel ("ellipse method"). A retrospective cohort study of 50 patients receiving free flap-based reconstruction of the LE was performed. Bilateral psoas density and area were quantified at L4 through tracing ("traditional method") and encircling ("ellipse method") to calculate Hounsfield unit average calculation (HUAC). Logistic regression and receiving operator curve analysis for the primary outcome of any postoperative complication was used to determine HUAC cutoffs (≤ 20.7 vs. ≤ 20.6) for sarcopenia. Risk of complications associated with sarcopenia was evaluated using Fisher's exact tests. Twelve patients (24%) met criteria for sarcopenia via the traditional method and 16 (32%) via the ellipse method. By both methods, sarcopenic patients were older and more often female and diabetic. These patients also had higher American Society of Anesthesiologists scores and lower serum prealbumin levels. The ellipse method was found to be more accurate, sensitive, and specific than the traditional method in predicting postoperative morbidity (p = 0.009). Via the ellipse method, sarcopenic patients were at higher risk for any complication (p = 0.002) and were at a higher risk for a deep vein thrombus or pulmonary embolism via the traditional method (p = 0.047). Sarcopenia is associated with greater pre- and postoperative morbidity in LE reconstruction. The novel ellipse method is a simplified and accurate method of assessing sarcopenia that can be easily performed in the clinical setting.
