Abstract
AIM To ascertain the association between body composition, including muscle mass and adiposity, and patient mortality in those requiring extracorporeal membrane oxygenation (ECMO) for acute respiratory failure. MATERIALS AND METHODS A retrospective study was undertaken of all patients with acute respiratory failure requiring veno-venous (VV) ECMO between January 2015 and December 2019. Automated image segmentation software was used to quantify the cross-sectional area and average radiodensity (in Hounsfield units) of different muscle and fat compartments at the L3 level of whole-body computed tomography (CT) images taken within 48 h of initiation of ECMO support. The primary endpoint was 30-day post-ECMO initiation all-cause mortality. Logistic regression was used to analyse the correlation between CT measurements, co-morbidities, and 30-day survival. RESULTS The study included 189 patients (age = 43.8 ± 14.6, sex = 42.3% female). There was no significant association between 30-day survival status and cross-sectional area of muscle or fat. Muscle attenuation (psoas, long spine, and abdominal muscles respectively) at the L3 level were significantly lower in those who died within 30 days of ECMO cannulation (p<0.05). On multivariable analysis including age, sex, and pre-existing respiratory comorbidities, psoas muscle attenuation was an independent predictor of survival at 30 days (OR 0.97; 95% CI 0.94 to 1.00; p=0.047). CONCLUSIONS Reduced psoas muscle attenuation is associated with poorer survival outcomes at 30 days post-ECMO cannulation in patients who received VV ECMO support for respiratory failure. Cross-sectional areas of muscle and fat compartments did not correlate with survival outcomes at 30 days even when corrected for height and sex.

Front Nutr 2023; 10:1117558. [PMID: 37252244 PMCID: PMC10213681 DOI: 10.3389/fnut.2023.1117558] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Accepted: 04/11/2023] [Indexed: 05/31/2023] Open
Abstract
Background Patients with critical illness often develop low skeletal muscle mass (LSMM) for multiple reasons. Numerous studies have explored the association between LSMM and mortality. The prevalence of LSMM and its association with mortality are unclear. This systematic review and meta-analysis was performed to examine the prevalence and mortality risk of LSMM among critically ill patients. Methods Three internet databases (Embase, PubMed, and Web of Science) were searched by two independent investigators to identify relevant studies. A random-effects model was used to pool the prevalence of LSMM and its association with mortality. The GRADE assessment tool was used to assess the overall quality of evidence. Results In total, 1,582 records were initially identified in our search, and 38 studies involving 6,891 patients were included in the final quantitative analysis. The pooled prevalence of LSMM was 51.0% [95% confidence interval (CI), 44.5-57.5%]. The subgroup analysis showed that the prevalence of LSMM in patients with and without mechanical ventilation was 53.4% (95% CI, 43.2-63.6%) and 48.9% (95% CI, 39.7-58.1%), respectively (P-value for difference = 0.44). The pooled results showed that critically ill patients with LSMM had a higher risk of mortality than those without LSMM, with a pooled odds ratio of 2.35 (95% CI, 1.91-2.89). The subgroup analysis based on the muscle mass assessment tool showed that critically ill patients with LSMM had a higher risk of mortality than those with normal skeletal muscle mass regardless of the different assessment tools used. In addition, the association between LSMM and mortality was statistically significant, independent of the different types of mortality. Conclusion Our study revealed that critically ill patients had a high prevalence of LSMM and that critically ill patients with LSMM had a higher risk of mortality than those without LSMM. However, large-scale and high-quality prospective cohort studies, especially those based on muscle ultrasound, are required to validate these findings.

Abstract
Frailty is an important risk factor for adverse health-related outcomes. It is classified into several phenotypes according to nutritional state and physical activity. In this context, we investigated whether frailty phenotypes were related to clinical outcome of hospital-acquired pneumonia (HAP). During the study period, a total of 526 patients were screened for HAP and 480 of whom were analyzed. The patients were divided into four groups according to physical inactivity and malnutrition: nutritional frailty (Geriatric Nutritional Risk Index [GNRI] < 82 and Clinical Frailty Scale [CFS] ≥ 4), malnutrition (GNRI < 82 and CFS < 4), physical frailty (GNRI ≥ 82 and CFS ≥ 4), and normal (GNRI ≥ 82 and CFS < 4). Among the phenotypes, physical frailty without malnutrition was the most common (39.4%), followed by nutritional frailty (30.2%), normal (20.6%), and malnutrition (9.8%). There was a significant difference in hospital survival and home discharge among the four phenotypes (p = 0.009), and the nutritional frailty group had the poorest in-hospital survival and home discharge (64.8% and 34.6%, respectively). In conclusion, there were differences in clinical outcomes according to the four phenotypes of HAP. Assessment of frailty phenotypes during hospitalization may improve outcomes through adequate nutrition and rehabilitation treatment of patients with HAP.

Abstract
OBJECTIVES To investigate the prevalence of low skeletal muscle index (area normalized for height) and density, their trajectory of change, and to determine associations with clinical outcome in adults with severe respiratory failure requiring venovenous extracorporeal membrane oxygenation. DESIGN Prospective observational study. PATIENTS Adults receiving venovenous extracorporeal membrane oxygenation for a minimum of 72 hours and a maximum of 6 months between September 2010 and June 2017, who had a CT scan which included the third lumbar vertebra. INTERVENTION None. MEASUREMENTS AND MAIN RESULTS Skeletal muscle index and density was determined using Slice-O-Matic V5.0 (TomoVision, Montreal, QC, Canada). Low skeletal muscle index and density were defined using published criteria. Regression models were used to assess for associations between muscle index and density and clinical outcome. Two-hundred fifteen patients, median (interquartile range) age 46 years (35.0-57.0 yr) were included. Forty-five patients (21.1%) had low skeletal muscle index, and 48 (22.3%) had low skeletal muscle density on commencement of venovenous extracorporeal membrane oxygenation. Low skeletal muscle index was more prevalent in males (28.8% vs 11.6%; χ2 = 9.4; p = 0.002) and was associated with a longer duration of venovenous extracorporeal membrane oxygenation (B = 5.0; 95% CI, 0.2-9.9; p = 0.042). Higher skeletal muscle density was independently associated with ICU survival (odds ratio 1.6 per 10 Hounsfield units; 95% CI, 1.1-2.5; p = 0.025). No relationship was observed between skeletal muscle index nor density and physical function. Adequacy of energy and protein did not influence change in skeletal muscle index or density. CONCLUSIONS Low skeletal muscle index at the commencement of venovenous extracorporeal membrane oxygenation was associated with a longer duration of venovenous extracorporeal membrane oxygenation, whereas preserved skeletal muscle density was associated with improved survival.

Abstract
BACKGROUND The evidence of sarcopenia based on CT-scan as an important prognostic factor for critically ill patients has not seen consistent results. To determine the impact of sarcopenia on mortality in critically ill patients, we performed a systematic review and meta-analysis to quantify the association between sarcopenia and mortality. METHODS We searched studies from the literature of PubMed, EMBASE, and Cochrane Library from database inception to June 15, 2020. All observational studies exploring the relationship between sarcopenia based on CT-scan and mortality in critically ill patients were included. The search and data analysis were independently conducted by two investigators. A meta-analysis was performed using STATA Version 14.0 software using a fixed-effects model. RESULTS Fourteen studies with a total of 3,249 participants were included in our meta-analysis. The pooled prevalence of sarcopenia among critically ill patients was 41 % (95 % CI:33-49 %). Critically ill patients with sarcopenia in the intensive care unit have an increased risk of mortality compared to critically ill patients without sarcopenia (OR = 2.28, 95 %CI: 1.83-2.83; P < 0.001; I2 = 22.1 %). In addition, a subgroup analysis found that sarcopenia was associated with high risk of mortality when defining sarcopenia by total psoas muscle area (TPA, OR = 3.12,95 %CI:1.71-5.70), skeletal muscle index (SMI, OR = 2.16,95 %CI:1.60-2.90), skeletal muscle area (SMA, OR = 2.29, 95 %CI:1.37-3.83), and masseter muscle(OR = 2.08, 95 %CI:1.15-3.77). Furthermore, critically ill patients with sarcopenia have an increased risk of mortality regardless of mortality types such as in-hospital mortality (OR = 1.99, 95 %CI:1.45-2.73), 30-day mortality(OR = 2.08, 95 %CI:1.36-3.19), and 1-year mortality (OR = 3.23, 95 %CI:2.08 -5.00). CONCLUSIONS Sarcopenia increases the risk of mortality in critical illness. Identifying the risk factors of sarcopenia should be routine in clinical assessments and offering corresponding interventions may help medical staff achieve good patient outcomes in ICU departments.

Abstract
Successful weaning from extracorporeal membrane oxygenation (ECMO) does not necessarily imply patient survival. We retrospectively analyzed 441 patients with acute respiratory failure from 16 hospitals in South Korea who underwent ECMO from January 2012 to December 2015. We evaluated the clinical factors associated with mortality after successful weaning from ECMO. Of all 441 patients, 245 (55.6%) were successfully weaned from ECMO. The majority of patients were initially supported with veno-venous ECMO (86.9%). Among those, 182 patients (41.3%) were discharged from hospital. Only 165 (37.4%) were alive after 6 months. Most cases of death occurred within the first month after weaning from ECMO (65%), and the most frequent reason for death was sepsis (76.2%). In the multivariate Cox regression analysis, patient age (per 10 years) (hazard ratio [HR] = 1.34, 95% CI = 1.12-1.61; p = 0.001), sequential organ failure assessment score (HR = 1.07, 95% CI = 1.02-1.13; p = 0.010), steroid (HR = 2.38, 95% CI = 1.27-4.45; p = 0.007), interstitial lung disease (HR = 1.20, 95% CI = 1.05-1.36; p = 0.006), and ECMO duration (per day) (HR = 1.02, 95% CI = 1.01-1.04; p < 0.001) were associated with the in-hospital mortality after weaning from ECMO. Furthermore, age (per 10 years) (HR = 1.45, 95% CI = 1.24-1.71; p < 0.001), steroid (HR = 2.19, 95% CI = 1.27-3.78; p = 0.005), and interstitial lung disease (HR = 1.16, 95% CI = 1.02-1.31; p = 0.021) were significantly associated with 6 month mortality. The prognosis after weaning from respiratory ECMO might be related to baseline conditions affecting the reversibility of the primary lung disease and to acquired infections.

Sarcopenia is a useful risk stratification tool to prognosticate splenic abscess patients in the emergency department. J Formos Med Assoc 2020; 120:997-1004. [PMID: 32917483 DOI: 10.1016/j.jfma.2020.08.039] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 08/18/2020] [Accepted: 08/25/2020] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND/PURPOSE Splenic abscess is a life-threatening surgical emergency which requires early diagnosis and intervention to maximize patient outcomes. This can be achieved through accurate risk stratification in the emergency department (ED). Sarcopenia refers to an age-related loss of skeletal muscle mass and strength that is accompanied by major physiologic and clinical ramifications, and often signifies decreased physiologic reserves. It is associated with poor clinical outcomes in sepsis, acute respiratory failure, oncological surgery, and liver transplantation. This study evaluates the utility of sarcopenia as a radiological stratification tool to predict in-hospital mortality of splenic abscess patients in the ED. This will assist emergency physicians, internists and surgeons in rapid risk stratification, assessing treatment options, and communicating with family members. METHODS 99 adult patients at four training and research hospitals who had undergone an abdominal contrast computed tomography scan in the ED with the final diagnosis of splenic abscess from January 2004 to November 2017 were recruited. Evaluation for sarcopenia was performed via calculating the psoas cross-sectional area at the level of the third lumbar vertebra and normalising for height, before checking it against pre-defined values. Univariate analyses were used to evaluate the differences between survivors and non-survivors. Sensitivity, specificity, and predictive values of the presence of sarcopenia in predicting in-hospital mortality were calculated. Kaplan-Meier methods, log-rank test, and Cox proportional hazards model were also performed to examine survival between groups with sarcopenia versus non-sarcopenia. RESULTS Splenic abscess patients with sarcopenia were 7.56 times more at risk of in-hospital mortality than those without sarcopenia (multivariate-adjusted HR: 7.56; 95% CI: 1.55-36.93). Presence of sarcopenia was found to have 84.62% sensitivity and 96.49% negative predictive value in predicting mortality. CONCLUSION Sarcopenia is associated with poor prognoses of in-hospital mortality in patients with splenic abscess presenting to the ED. We recommend its use in the ED to rapidly risk stratify and predict outcome to guide treatment strategies.
