Objective To investigate the prognostic value of sarcopenia in patients with early non-small cell lung cancer (NSCLC) after surgery and chemotherapy. Methods This study included 592 patients with early non-small cell lung cancer who received lung cancer resection from January 2014 to December 2015, and they were divided into two groups: 473 patients received surgery alone (the surgery group), 119 patients received chemotherapy after surgery (the postoperative chemotherapy group), and the two groups were divided into sarcopenia group and non-sarcopenia group. General clinical data, laboratory data, and imaging data of these patients were compared. Results The median follow-up time of 592 patients was 69.1 months [95% confidential interval (CI) 64.9 - 78.2], and 110 patients were with sarcopenia (18.6%). Multivariate analysis showed that sarcopenia was an independent adverse prognostic factor in the surgery group [hazard ratio (HR) 6.56; 95%CI 1.86 to 14.78; P=0.01]. For patients undergoing postoperative chemotherapy, skeletal muscle mass index was reduced after chemotherapy, and sarcopenia was an independent predictor of poor prognosis (HR 5.77; 95%CI 0.96 to 20.60; P<0.05). Conclusions Sarcopenia is an independent poor prognostic factor for patients with early NSCLC undergoing surgery and postoperative chemotherapy. Assessment of sarcopenia before surgery and postoperative chemotherapy is helpful to improve the prognosis of patients with early NSCLC.
Objective To investigate the relevance among sarcopenia, peripheral inflammatory, and nutritional factors, as well as the impact of sarcopenia on the prognosis of gastric cancer. Methods A total of 174 patients with gastric cancer in Department of Gastrointestinal Surgery in West China Hospital of Sichuan University from July 2016 to December 2020 were retrospectively included. The skeletal muscle index (SMI) of the third lumbar vertebra level was calculated using CT images, and male patients with SMI<52.4 cm2/m2 and female patients with SMI<38.5 cm2/m2 were considered sarcopenia. The key clinicopathological features of patients were collected for prognostic analysis. ResultsAmong the 174 patients with gastric cancer, 73 patients (41.95%) were diagnosed with sarcopenia. Compared with those of non-sarcopenia, the patients who were diagnosed with sarcopenia showed a significantly elder age and lower body mass index (BMI). In addition, males demonstrated a significantly higher rate of sarcopenia. Further, patients with sarcopenia showed a significant increasing in the incidence of postoperative pulmonary infections and length of hospitalization than patients without sarcopenia. The two groups showed significant differences in type 2 diabetes, peripheral C-reaction protein (CRP), interleukin-6 (IL-6), albumin, prealbumin, and hemoglobin. Overall, the multivariate analysis and Kaplan-Meier survival curves indicated that sarcopenic patients had a significantly lower survival rate than the non-sarcopenia patients. Conclusion Sarcopenia is closely related to higher levels of inflammation, malnutrition, and poor prognosis in patients with gastric cancer. Therefore, we should diagnose sarcopenia patients as early as possible, and give nutritional support to the patients.
Sarcopenia, a skeletal muscle degenerative condition, is inextricably linked to the physiological processes of aging. Sarcopenia is characterized by a reduction in muscle mass, a decline in muscle strength, and/or deterioration of physical function. Comprehensive interventions are essential for the management of sarcopenia. The team from the National Clinical Research Center for Geriatrics has authored the "Comprehensive intervention for sarcopenia among older adults: an evidence-based clinical practice guideline" which discuss the specific contents of exercise, nutrition, and drug interventions for sarcopenia. This article provides a comprehensive interpretation of the guideline to facilitate their dissemination, promotion, and application.
Sarcopenia has the characteristics of high morbidity and mortality, which seriously affects the quality of life of patients. Continuity of care, as an emerging nursing model in recent years, aims to improve self-care abilities of patients and their families, which can effectively reduce the rate of rehospitalization, and improve the quality of life of patients. This article starts with psychological intervention, nutrition guidance, patient exercise and medication guidance, and explores the application of continuity of care in patients with end-stage renal disease complicated with sarcopenia, analyzes the application of continuity of care in patients with end-stage renal diseases, and describes the implementation content and form of continuity of care, aiming to help its further promotion in clinic.
Sarcopenia is a syndrome associated with reduced strength, mass and function of skeletal muscles. Aging of gastric cancer patients, lack of nutritional intake, and pathological mechanisms of gastric cancer increase the likelihood of sarcopenia. Sarcopenia is associated with the development of gastric cancer and may be a risk factor for the formation of gastric cancer. Sarcopenia is closely related to the prognosis and treatment of gastric cancer. At present, the treatment of sarcopenia is still in the exploratory stage, and more research is needed to obtain better treatment plans and improve the quality of life of patients. This article reviews the research status of sarcopenia and gastric cancer in order to provide evidence for clinical research.
Objective To investigate the impact of sarcopenia on effectiveness of lumbar decompression surgery in patients with lumbar spinal stenosis. Methods The clinical data of 50 patients with lumbar spinal stenosis who met the selection criteria between August 2017 and December 2020 were retrospectively analyzed. According to the diagnostic criteria of the European Working Group on Sarcopenia in Older People (EWGSOP), based on the calculation of the skeletal muscle index (SMI) at the L3 level, SMI<45.4 cm2/m2 (men) and SMI<34.4 cm2/m2 (women) were used as the diagnostic threshold, the patients were divided into sarcopenia group (25 cases) and non-sarcopenia group (25 cases). There was no significant difference in gender, age, disease duration, level of lumbar spinal stenosis, surgical fusion level, and comorbidity between the two groups (P>0.05); the body mass index in sarcopenia group was significantly lower than that in non-sarcopenia group (t=−3.198, P=0.002). Clinical data of the two groups were recorded and compared, including operation time, intraoperative blood loss, postoperative drainage volume, hospitalization stay, and complications. The visual analogue scale (VAS) scores of low back pain and sciatica and Oswestry disability index (ODI) scores were recorded preoperatively and at last follow-up. The effectiveness was evaluated according to modified MacNab standard. Results There was no significant difference between the two groups in terms of operation time, intraoperative blood loss, and postoperative drainage volume (P>0.05). However, the hospitalization stay in sarcopenia group was significantly longer than that in non-sarcopenia group (t=2.105, P=0.044). The patients were followed up 7-36 months (mean, 29.7 months). In sarcopenia group, 1 case of dural tear and cerebrospinal fluid leakage occurred during operation, as well as 1 case of internal fixator loosening during follow-up; 1 case of incision exudation and poor healing occurred in each of the two groups, and no adjacent segment degeneration and deep vein thrombosis of lower extremity occurred in the two groups during follow-up. There was no significant difference in the incidence of complications (12% vs. 4%) between the two groups (χ2=1.333, P=0.513). VAS scores in low back pain and sciatica as well as ODI scores in two groups significantly improved when compared with preoperative results at last follow-up (P<0.05). The differences of VAS scores in low back pain and ODI scores before and after operation in sarcopenia group were significantly lower than that in non-sarcopenia group (P<0.05). However, there was no significant difference of that in VAS scores of sciatica between the two groups (t=−1.494, P=0.144). According to the modified MacNab standard, the excellent and good rate of the sarcopenia group was 92%, and that of the non-sarcopenia group was 96%, showing no significant difference between the two groups (χ2=1.201, P=0.753). ConclusionPatients with sarcopenia and lumbar spinal stenosis may have longer postoperative recovery time, and the effectiveness is worse than that of non-sarcopenic patients. Therefore, for elderly patients with lumbar spine disease, it is suggested to improve preoperative assessment of sarcopenia, which can help to identify patients with sarcopenia at risk of poor surgical prognosis in advance, so as to provide rehabilitation guidance and nutritional intervention in the perioperative period.
Sarcopenia, characterized by the progressive loss of muscle mass and function, predominantly afflicts older adults. This condition is a notable risk factor for functional impairments, increased incidence of falls and fractures, and can escalate to mortality. Timely intervention is crucial to mitigate disability and minimize complications during hospitalization. The development of these guidelines adhered to an internationally recognized standard protocol. This involved framing clinical queries, pinpointing key outcomes, systematically gathering evidence, and appraising this evidence through the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework. Subsequently, a consortium of experts convened to deliberate over the evidence, culminating in the formulation of these recommendations.
ObjectiveTo systematically review the prevalence of cognitive impairment in patients with sarcopenia. MethodsThe PubMed, EMbase, Web of Science, Cochrane Library, CBM, CNKI, VIP and WanFang Data databases were electronically searched to collect studies related to the objectives from inception to December 10, 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using Stata 14.0 software. ResultsA total of 27 studies were included. The overall prevalence rate of cognitive impairment in sarcopenia was 36.1% (95%CI 29.4% to 42.8%). Subgroup analysis showed that the prevalence in Europe was higher than that in other areas. The prevalence of nursing home residents was highest. ConclusionCurrent evidence shows that the prevalence of cognitive impairment in patients with sarcopenia is high. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
ObjectiveTo systematically review the correlation between sarcopenia and cognitive dysfunction. MethodsCNKI, WanFang Data, PubMed, EMbase and Web of Science databases were electronically searched to collect studies on the correlation between sarcopenia and cognitive dysfunction from inception to June 15, 2022. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.3 and Stata 14.0 software. ResultsA total of 13 studies involving 19 262 subjects were included. Meta-analysis showed that the cognitive dysfunction was significantly associated with sarcopenia (OR=1.82, 95%CI 1.58 to 2.11, P<0.01). The results of subgroup analysis showed that the cognitive dysfunction was significantly associated with sarcopenia in Asia and Europe. However, the incidence of cognitive dysfunction in the Americas was not significantly associated with sarcopenia. ConclusionCurrent evidence shows that there is a significant correlation between sarcopenia and cognitive dysfunction, but there may be differences in different regions. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
