RESUMO

It is essential to further characterize liver injury aimed at developing novel therapeutic approaches. This study investigated the mechanistic basis of genipin against carbon tetrachloride (CCl4)-triggered acute liver injury concerning ferroptosis, a novel discovered modality of regulated cell death. All experiments were performed using hepatotoxic models upon CCl4 exposure in mice and human hepatocytes in vitro. Immunohistochemistry, immunoblotting, molecular docking, RNA-sequencing and ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) were conducted. CCl4 intoxication was manifested with lipid peroxidation-dictated ferroptotic cell death, together with changes in a cascade of ferroptosis-associated events and several regulatory pathways. Both the administration of genipin and ferrostatin-1 (Fer-1) significantly prevented this hepatotoxicity in response to CCl4 intoxication via upregulating GPX4 and xCT (i.e., critical regulators of ferroptosis). RNA-sequencing unraveled that arachidonic acid metabolism was considerably influenced upon genipin treatment. Accordingly, genipin treatment attenuated arachidonate 15-lipoxygenase (ALOX15)-launched lipid peroxidation in terms of UHPLC-MS/MS analysis and inflammation. In vitro, genipin supplementation rescued erastin-induced hepatocellular inviability and lipid ROS accumulation. The siRNA knockdown of GPX4 partially abrogated the protective effects of genipin on erastin-induced cytotoxicity, whereas the cytotoxicity was less severe in the presence of diminished ALOX15 expression in L-O2 cells. In conclusion, our findings uncovered that genipin treatment protects against CCl4-triggered acute liver injury by abrogating hepatocyte ferroptosis, wherein the pharmacological modification of dysregulated GPX4 and ALOX15-launched lipid peroxidation was responsible for underlying medicinal effects as molecular basis.

RESUMO

Frailty corresponds to an emerging construct in the hepatology which is originally introduced as a validated geriatric syndrome regarding increased vulnerability to pathophysiological stressors. As for patients with cirrhosis, the presence of frailty is indicative of debilitating conditions that subjects are prone to deleterious acute insults and have difficulties to restore even if the underlying liver function partially returned to normal levels. Since this conceptual development, a variety of tools assessing frailty have been proposed and evaluated in the context of cirrhosis. A recent performance-based metric for frailty, designated as Liver Frailty Index, has broadly been applied in patients with cirrhosis and exhibited acceptable predictive ability in relation to disease progression, mortality and hospitalization. However, those functional tests measuring frailty may be impossible to perform in circumstance that patients are critically ill or undergoing detrimental events. An interesting modality indicates the use of alternative tests to evaluate frailty, which may be more adaptable and of choice for specific subgroups. The interrelation between frailty and various cirrhosis-associated pathological entities is of clinical importance and implication. Noticeably, it is imperative to clarify these complex linkages to highlight novel therapeutic targets or interventional endpoints. The efficient and effective management of frailty is still challenging, but many attempts have been made to overcome barriers of affordability and availability. Some clinical trials on small scale revealed that home-based exercise and individualized nutrition therapy show benefits in patients with cirrhosis, and high adherence to the treatment regimen may direct better efficacy and performance.

RESUMO

Patients with cirrhosis experience worse health-related quality of life (HRQoL), and attempts are warranted further exploration of modifiable factors to improve HRQoL. Data on the impact of malnutrition risk on HRQoL among cirrhosis are limited; thus, we aimed to strengthen understanding by clarifying the relationship between nutritional status and low HRQoL in patients with decompensated cirrhosis. Consecutive inpatients with cirrhosis attending our department within a tertiary hospital were studied. Generic health profiles and malnutrition risk were evaluated by the EuroQol-5D (EQ-5D) and Royal Free Hospital-Nutritional Prioritizing Tool (RFH-NPT) score, respectively. Multiple linear regression analysis was used to determine association of malnutrition risk with low HRQoL. In this cohort of 364 patients with median age of 64 years and 49·5 % male, 55·5 % of the study population reported impairment pertinent to HRQoL in at least one dimension in terms of the EQ-5D. Moreover, malnutrition risk (RFH-NPT score: ß coefficient = -0·114, P = 0·038) was proved to be independently associated with poor HRQoL in multiple analysis, after adjustment for significant variables like age, BMI and markers of decompensation. Notably, we found that health dimensions representing physical function (i.e. mobility, self-care and usual activities) are substantially affected, while malnourished patients reported less frequencies of complaints in other domain such as anxiety/depression. In conclusion, the risk of malnutrition assessed by the RFH-NPT score is independently associated with low HRQoL. It is operational to improve HRQoL by identifying patients at high malnutrition risk and providing timely nutrition treatment.

RESUMO

INTRODUCTION: The synergistic impact of coexistent malnutrition and sarcopenia on morality in hospitalized patients with decompensated cirrhosis remains elusive. This prospective cohort study aimed to delineate the prevalence concerning coexistence of malnutrition and sarcopenia and the prognosticating role on long-term mortality among cirrhosis. METHODS: Adult cirrhotic patients with decompensated episodes between 2019 and 2021 were consecutively enrolled. Malnutrition and sarcopenia were diagnosed according to the Global Leadership Initiative on Malnutrition (GLIM) criteria and the European Working Group on Sarcopenia in Older People (EWGSOP2) algorithm, respectively. The entire cohort was divided into three groups: non-malnutrition and non-sarcopenia (NN), malnutrition or sarcopenia, and coexistent malnutrition and sarcopenia (MS). Log-rank test and multivariate Cox regression model were utilized to evaluate survival status and independent risk factors for mortality, respectively. RESULTS: Our findings indicated that malnutrition manifested in 44.6% of inpatients with decompensated cirrhosis, while sarcopenia presented in 16.4% of the entire cohort, indicative of a prevalence of 14.7% regarding coexistent malnutrition and sarcopenia. The Kaplan-Meier graphic demonstrated a significant difference regarding survival curves among the three groups, referring to the MS group presented with the lowest survival rate (log-rank test: p < 0.001). Moreover, coexistent malnutrition and sarcopenia were associated with nearly 4 times higher mortality risk (model 1: hazard ratio [HR] = 3.31, 95% confidence interval [CI]: 1.20-9.13, p = 0.020; model 2: HR = 4.34, 95% CI: 1.52-12.4, p = 0.006) in comparison with patients without any condition (NN group). CONCLUSIONS: Malnutrition and sarcopenia had superimposed negative impacts on inpatients with decompensated cirrhosis. It is imperative to identify this vulnerable subset to provide prompt therapeutic intervention for better prognosis.

RESUMO

BACKGROUND: Myosteatosis indicates pathological fat infiltration in muscles and is regarded as a distinct disease from sarcopenia. This muscular condition exhibits a link to muscle fiber disarrangement coinciding with disrupted muscle contractility and weakened mechanical action, mirrored as decreased muscle quality. However, the relationship between handgrip strength (HGS) and computed tomography-defined myosteatosis among cirrhosis is unclear. We aimed to investigate the association between HGS and myosteatosis and determine gender-specific cutoffs regarding HGS to identify myosteatotic subjects. METHODS: We prospectively recruited 221 cirrhotic patients. The presence of myosteatosis was determined according to intramuscular adipose tissue content. The relationship between HGS and myosteatosis was evaluated according to Spearman correlation coefficient, area under the ROC curve, and multivariate logistic regression analysis. Moreover, a model based on the classification and regression tree method was generated. RESULTS: Our results showed that HGS exhibits modestly negative correlation with intramuscular adipose tissue content in the entire cohort (rs = -0.269, P < .001) and across diverse subgroups precluding extremely deteriorating conditions. After controlling for multiple clinical features and biochemical parameters, HGS (odds ratio = 0.921, P = .010) was independently associated with myosteatosis in addition to age and body mass index. On applying the Japan Society of Hepatology-recommended cutoffs, an area under the ROC curve of HGS was 0.627 with a sensitivity of 77.4% and a specificity of 47.9%. The decision tree including body mass index and low HGS correctly classified ~85% of the cases in development and validation sets. CONCLUSIONS: HGS was in close relation to myosteatosis among inpatients with cirrhosis.

RESUMO

Fibronectin type III domain-containing protein 5 (FNDC5) is a transmembrane protein and the precursor of irisin, which serves as a systemic exerkine/myokine with multiple origins. Since its discovery in 2012, this hormone-like polypeptide has rapidly evolved to a component significantly involved in a gamut of metabolic dysregulations and various liver diseases. After a decade of extensive investigation on FNDC5/irisin, we are still surrounded by lots of open questions regarding its diagnostic and therapeutic values. In this review, we first concentrated on the structure-function relationship of FNDC5/irisin. Next, we comprehensively summarised the current knowledge and research findings regarding pathogenic roles/therapeutic applications of FNDC5/irisin in the context of non-alcoholic fatty liver disease, fibrosis, liver injury due to multiple detrimental insults, hepatic malignancy and intrahepatic cholestasis of pregnancy. Moreover, the prominent molecules involved in the underlying mechanisms and signalling pathways were highlighted. As a result, emerging evidence reveals FNDC5/irisin may act as a proxy for diagnosing liver disease pathology, a sensitive biomarker for assessing damage severity, a predisposing factor for surveilling illness progression and a treatment option with protective/preventive impact, all of which are highly dependent on disease grading and contextually pathological features.

RESUMO

Regenerating gene (REG) family proteins serve as multifunctional secretory molecules with trophic, antiapoptotic, anti-inflammatory, antimicrobial and probably immuno-regulatory effects. Since their discovery, accumulating evidence has clarified the potential roles of the REG family in the occurrence, progression and development of a wide range of inflammatory and inflammation-associated diseases of the gastrointestinal (GI) tract. However, significant gaps still exist due to the undefined nature of certain receptors, regulatory signaling pathways and possible interactions among distinct Reg members. In this narrative review, we first describe the structural features, distribution pattern and purported regulatory mechanisms of REG family proteins. Furthermore, we summarize the established and proposed roles of REG proteins in the pathogenesis of various inflammation-associated pathologies of the GI tract and the body as a whole, focusing particularly on carcinogenesis in the ulcerative colitis-colitic cancer sequence and gastric cancer. Finally, the clinical relevance of REG products in the context of diagnosis, treatment and prognostication are also discussed in detail. The current evidence suggests a need to better understanding the versatile roles of Reg family proteins in the pathogenesis of inflammatory-associated diseases, and their broadened future usage as therapeutic targets and prognostic biomarkers is anticipated.

RESUMO

Scoparone is an active and efficious ingredient of herbal medicine Artemisia capillaris Thunb, which has been used clinically in traditional Chinese medicine formula (e.g. Yin-Chen-Hao decoction) for the treatment of hepatic dysfunction, cholestasis and jaundice for over thousand years. More recently, scoparone has received increasing attention due to its multiple properties. In this comprehensive review, we provide the first summary of the pharmacological effects and pharmacokinetic characteristics of scoparone, and discuss future research prospects. The results implicated that scoparone possesses a wide spectrum of pharmacological activities, including anti-inflammatory, antioxidant, anti-apoptotic, anti-fibrotic and hypolipidemic properties. Pharmacokinetic studies have addressed that isoscopoletin and scopoletin are major primary metabolites of scoparone. Moreover, hepatic dysfunction might promote bioavailability of scoparone due to limited intrinsic clearance. On the other hand, the bioavailability of multi-component including scoparone in certain TCM formula can also be enhanced by applying this formula at a high dose on account of their interacted effects. In view of good pharmacological actions, scoparone is anticipated to be a potential drug candidate for various liver diseases, such as acute liver injury, fulminant hepatitis, alcohol-induced hepatotoxicity, non-alcoholic fatty liver disease and fibrosis. However, further studies are warranted to clarify its molecular mechanisms and targets, elucidate its toxicity, and identify its interplay with other active ingredients of classical TCM formula in clinical settings.

RESUMO

AIM: To investigate whether endoscopic treatment is applicable to American patients and explores the predictors of lymph node metastasis (LNM) in early gastric cancer (EGC). METHODS: Patients with EGC confined to either mucosa (T1a, n = 1799) and submucosa (T1b, n = 1689) were identified from the Surveillance, Epidemiology, and End Result database. Multivariate logistic regression, Kaplan-Meier method, and univariate/multivariate Cox regression were used to assess the correlation between invasion depth and LNM or prognosis. A nomogram for predicting LNM was constructed and internally validated. RESULTS: EGC limited to T1a exhibited a 2.4% incidence of LNM, which increased to 11.1% when the depth invaded T1b.LNM was present at 1.4%, 5.2%, and 5.0% for sizes ≤2, 2-5, and >5cm of low-grade T1a EGC, respectively, (p = .019) and at 4.8%, 12.4%, and 28.6% of T1b EGC, respectively (p < .001).The multivariate logistic model revealed that older age, T1b invasion, larger tumor size, and high-grade lesions were associated with a higher risk of LNM. Moreover, the T1a EGC patients had better cancer-specific survival (OS) and overall survival(CSS) compared with the T1b EGC patients (5-year OS: 77.2% versus 67.4%, p < .001; 5-year CSS: 90.6% versus 81.4%, p < .001). The discrimination of the prediction model was 0.745. CONCLUSIONS: Endoscopic treatment may only be suitable for patients in the US population who have low-grade T1a lesions of less than 2 cm in size. Patients with T1a lesions of greater than 2 cm in size, lesions with high-grade, and all T1b lesions may benefit from radical surgical resection with lymphadenectomy.

RESUMO

Objectives: To evaluate the safety and efficacy of endoscopic resection and discuss the treatment strategy of small gastric gastrointestinal stromal tumors (GISTs) less than 2 cm. Material and methods: The data of 713 patients, who underwent endoscopic submucosal dissection (ESD) for gastric submucosal tumors (SMTs), were retrospectively analyzed. We investigated the clinicopathological features and analyzed the risk potential of small gastric GISTs, and documented therapeutic and follow-up outcomes. We also compared the follow-up results between operated patients and 58 patients who were suspected of small gastric GISTs and underwent regular surveillance under endoscopic ultrasound (EUS) in the same period. Results: GISTs were the most common gastric SMTs (289 cases, 40.5%), of which small GISTs were found in 250 cases. The mitotic index was less than 5 in all cases. However, 122 out of 250 cases (48.8%) had adverse factors under EUS, which were related to tumor size (p < .01). ESD was successfully performed in all patients, and no serious complication or perioperative death occurred. The follow-up period for 42.07 ± 22.49 months revealed improvement of symptoms in 80.2% patients and showed no recurrence or metastasis. Of the 58 patients selected for EUS surveillance, 48 (82.8%) presented with gastrointestinal symptoms and 41 out of 48 (85.4%) were not relieved during follow-up and 16 (27.6%) with severe psychological problems. Conclusions: ESD is a safe and effective treatment for small GISTs, which helps to confirm the diagnosis, improve symptoms and reduce the psychological pressure. Thus, we recommend endoscopic resection is a good option for small gastric GISTs once diagnosed.

RESUMO

Chemical constituents of the Euphorbia sikkimensis roots was investigated and twelve known compounds were isolated, including three ent-atisane diterpenes: ent-(13S)-hydroxyatis-16-ene-3,14-dione (1), ent-(5ß,8α,9ß,10α,11α,12α)-11-hydroxyatis-16-ene-3,14-dione (2), ent-atisane-3-oxo-16α,17-diol (3); two kaurene diterpenes: ent-kaurane-3-oxo-16α,17-diol (4), ent-kaurane-3-oxo-16ß,17-diol (5); one lathyane diterpene of latilagascene B (6); two flavonoids: quercetin (7), luteolin (8); one lignin d-pinoresinol (9); one coumarin scopoletin (10); together with ethyl gallate (11), p-hydroxybenzaldehyde (12). Their structures were identified based on the extensive spectroscopic analysis in comparison with the literature data. Compounds 1, 2, 4, 6 and 9 were isolated from Euphorbia sikkimensis for the first time. The agonistic activity of peroxisome proliferator-activated receptor gamma (PPARγ) for compounds 1, 7, 8, 9 and 11 was evaluated. Compound 1 exhibited moderate agonistic activity for PPARγ receptor with relative fluorescence intensity of 10.19 at 30.0 µM, in comparison with that of the positive control of rosiglitazone (28.50 at 2.0 µM).

RESUMO

BACKGROUND AND OBJECTIVES: There is limited evidence concerning the predictive value of health-related quality of life (HRQoL) on the presence of frailty in the context of cirrhosis. We aimed to elucidate the relationship between HRQoL and multidimensional frailty and to determine which HRQoL dimension independently impacted frail phenotype in our established cohort. METHODS: This was a prospective observational study by consecutively enrolling 355 patients with cirrhotic with decompensated signs in China. The HRQoL and frail phenotype were evaluated by the EuroQol-5D (EQ-5D) Questionnaire and Frailty Index, respectively. The relationship between EQ-5D utility index, as well as respective EQ-5D dimension, and Frailty Index was analysed according to the multiple linear regression analyses. RESULTS: More than half of the patients (56.3%) reported problems in any dimension of the EQ-5D, suggestive of impaired HRQoL. Moreover, the proportion of patients experiencing some/extreme problems significantly increased across all five dimensions (all p<0.001) in correspondence to transition from the robust to frail phenotype. Multiple linear regression analyses demonstrated that age, ascites and hepatic encephalopathy were positively associated with Frailty Index, while EQ-5D utility index (standardised ß coefficient= -0.442, p<0.001) negatively associated with Frailty Index. Notably, usual activities, self-care and mobility were the most influencing predictors associated with frailty. CONCLUSIONS: Our results support a rapid HRQoL assessment via EQ-5D may assist in predicting multidimensional frailty, and usual activities, self-care and mobility tend to be remediable targets while taking their effect on frail phenotype into consideration among patients with cirrhosis.

RESUMO

Purpose: The utility of the EuroQol Group 5 Dimension (EQ-5D) measuring health-related quality of life (HRQoL) has been verified; however, knowledge gaps remain concerning predictive performance in cirrhosis. We aimed to identify the optimal threshold for risk stratification and the pronounced domain in the EQ-5D linked to inferior outcomes. Patients and Methods: The X-tile project was used to obtain a threshold, considering the composite outcome of 1-year all-cause mortality or readmission. A restricted cubic spline (RCS) was performed to test the non-linear relationship between the EQ-5D utility value and the primary outcome. Six multivariate Cox regression models incorporating EQ-5D utility value and each of the five domains were constructed. Setting/Participants: Totally, 420 patients with cirrhosis were recruited. Results: The median utility value of the study population was 0.77 and 59.8% reported impairment in minimal one EQ-5D domain. RCS indicated a linear relationship between the utility value and composite inferior outcome. X-tile pinpointed a utility value of 0.59 stratifying populations into high- and low-risk groups based on the outcome. Inpatients with cirrhosis and deteriorated HRQoL (utility value ≤0.59) were at higher risk of death or readmission (adjusted HR: 2.18, P < 0.001). Furthermore, mobility and usual activities were the most pronounced domains associated with composite inferior outcome. Conclusion: A utility value ≤0.59 can identify cirrhotic inpatients exhibiting compromised HRQoL and mortality/readmission risk. It is tempting to reverse the decreased HRQoL by applying longitudinal measurements and keeping surveillance on utility value, while interventions appear to mainly focus on improving mobility and usual activities.

RESUMO

BACKGROUND: Dynapenia embraces clinical significance and predictive value separated from skeletal muscle loss among cirrhosis. Moreover, alterations in lipid levels may impact muscle function. It has yet to elucidate the relationship between lipid profiles and muscle strength weakness. We sought to explore which lipid metabolism indicator could be useful to identify patients with dynapenia in daily practice. METHODS: A retrospective observational cohort study enrolling 262 cirrhotic patients. Analysis of the receiver operating characteristic (ROC) curve was performed to determine the discriminatory cutoff for dynapenia. Multivariate logistic regression was conducted to assess the association between total cholesterol (TC) and dynapenia. Also, we established a model based on the classification and regression tree method. RESULTS: ROC implicated a cutoff of TC ≤ 3.37 mmol/L to identify dynapenia. Patients with TC ≤ 3.37 mmol/L showed significantly lower handgrip strength (HGS; 20.0 vs. 24.7 kg, P = 0.003), lower hemoglobin, lower platelet, lower white blood cell count, lower sodium and higher prothrombin-international normalized ratio. A positive correlation was found between TC and HGS values ( r = 0.1860, P = 0.003). TC remained a significant association with dynapenia after controlling for variables including age, sex, BMI, and the presence of ascites. The decision tree incorporating TC, BMI, and age had a sensitivity of 71.4%, specificity of 64.9%, and an area under ROC of 0.681. CONCLUSION: TC ≤ 3.37 mmol/L was significantly associated with the presence of dynapenia. Assessing TC may be helpful for identifying dynapenic patients with cirrhosis in the health care or hospital setting.

RESUMO

Background: Sleep disturbance and trace elements imbalance are common features in patients with decompensated cirrhosis, partially sharing similar mechanistic contributors and linking to adverse outcomes. However, there is a paucity of data concerning their relationship. Objectives: To investigate the association between serum trace elements levels and sleep quality in the context of cirrhosis. Design: Cross-sectional study. Methods: We consecutively enrolled 160 patients with decompensated cirrhosis. The sleep disturbance was determined by the Pittsburgh Sleep Quality Index (PSQI > 5). Serum trace elements [magnesium, calcium, iron, copper (Cu), zinc (Zn), lead, and manganese] was measured by inductively coupled plasma mass spectrometry. Association of examined trace elements levels and sleep disturbance was analyzed by multiple linear (global PSQI scores) and multivariate logistic (dichotomized PSQI categories) regression models, respectively. Results: In total, 91 patients (56.88%) represented PSQI-defined sleep disturbance, characterized by female preponderance, lower body mass index levels, and higher serum Cu levels (all p < 0.05). Looking into its clinical relevance with debilitating conditions, we showed that Cu/Zn ratio (CZr) is significantly higher in cirrhosis with poor sleep quality (1.77 versus 1.48, p = 0.003). Diagnostic performance analysis indicated CZr > 1.62 to exhibit better discrimination relative to respective Cu. Both multiple linear (ß = 0.355, p < 0.001) and multivariate logistic regression (odds ratio = 2.364, p = 0.019) identified higher CZr as an independent risk factor associated with sleep disturbance. Conclusion: Our findings implied an association between higher CZr and the presence of sleep disturbance in patients with decompensated cirrhosis.

RESUMO

OBJECTIVES: Malnutrition is prevalent and negatively affects patients with cirrhosis, but a generally accepted consensus pertaining to its diagnosis is lacking. Recently, a framework called the Global Leadership Initiative on Malnutrition (GLIM) has been proposed to diagnose malnutrition, but there is scant evidence regarding its validity. We aimed to investigate associations of malnutrition according to the GLIM criteria, as well as its individual indicator with in-hospital adverse outcomes. METHODS: This was a prospective, observational study of consecutively hospitalized patients with cirrhosis. The malnutrition diagnosis was built on a stepwise GLIM process with initial screening, followed by fulfillment of at least one phenotypic and one etiologic criterion. Patients were followed up for a combined endpoint of in-hospital mortality and prolonged length of stay (LOS). Covariates compromise malnutrition according to the GLIM criteria and its indicators in separation. Logistic regression analyses were implemented to determine predictive validity. RESULTS: A total of 387 cirrhotic patients were assessed. Malnutrition was diagnosed in 28.7% of patients according to the GLIM criteria, and increased the risk of in-hospital mortality and prolonged LOS by 2.166 and 1.767 times, respectively, adjusting for age, sex, biochemical parameters, and clinical scores of disease severity. When analyzing separate criteria, all constituents were independently associated with in-hospital adverse outcomes, adjusting for model for end-stage liver disease sodium score. CONCLUSIONS: Malnutrition according to the GLIM criteria was considerably prevalent among hospitalized patients with cirrhosis, and associated with approximately two times greater probability of in-hospital mortality and prolonged LOS. These diagnostic criteria may be implemented and disseminated during daily practice considering their predictive validity.

RESUMO

BACKGROUND: The Global Leadership Initiative on Malnutrition (GLIM) has been built to diagnose malnutrition; however, its validity among patients with cirrhosis remains enigmatic. We aimed to investigate the prevalence of malnutrition according to GLIM criteria and compare the differences by using a specific screening tool. METHODS: We conducted a descriptive cross-sectional study analyzing hospitalized patients. The Royal Free Hospital-Nutritional Prioritizing Tool (RFH-NPT) was chosen as the screening tool. Estimated prevalence was shown with and without the initial screening process. Diverse combinations of phenotypic and etiologic criteria and distinct body mass index (BMI) cutoffs were applied to detect frequency of malnourished patients with cirrhosis. RESULTS: Overall, 363 patients were recruited (median age, 64 years; 51.2% female). The prevalence of malnutrition according to GLIM criteria with and without RFH-NPT screening was 33.3% and 36.4%, respectively. Low BMI and inflammation represented the most prevalent combination resulting in a malnutrition diagnosis (42.4%), followed by low BMI and reduced food intake (39.4%). By contrast, the least prevalence was found when combining reduced muscle mass with inflammation to diagnose malnutrition. Furthermore, the frequency of malnourished and well-nourished participants was not statistically different when using divergent BMI reference values across the study population. CONCLUSIONS: GLIM criteria may serve a specific proxy to diagnose malnutrition, along with RFH-NPT screening. Relevant investigation is required to report on the applied combination of phenotypic/etiologic criteria, taking into consideration the marked impact of different models. More attempts are warranted to delineate the prognostic role of GLIM criteria in the context of cirrhosis.

RESUMO

The associations of circulating trace elements with sleep health have attracted increasing attention given their potential link. However, there is scant data on the relationship between serum trace elements and abnormal sleep duration patterns in cirrhosis. We aimed to investigate these associations with the purpose of identifying modifiable risk factors. The blood samples were collected from inpatients with cirrhosis, and serum levels of several trace elements were assessed by inductively coupled plasma mass spectrometry. Self-reported sleep duration was categorized to short- (< 7 h/night), optimal (7-8 h/night), and long-sleep duration (> 8 h/night). The dose-response trends and associations of trace elements levels with sleep duration were determined by restricted cubic splines (RCS) and logistic regression, respectively. Cirrhotic patients with optimal sleep duration experienced the highest levels of serum Zinc (Zn) and the lowest values of copper to zinc ratio (CZr). RCS model corroborated non-linear associations of serum Zn and CZr against sleep duration. Multiple regression analysis showed that both CZr (short vs optimal sleep duration: OR 4.785, P < 0.001; long vs optimal sleep duration: OR 4.150, P = 0.019) and serum Zn levels (short vs optimal sleep duration: OR 0.985, P = 0.040; long vs optimal sleep duration: OR 0.956, P = 0.008) serve as independent risk factors for sleep duration abnormalities. In conclusion, our findings unraveled a close relationship of serum Zn and CZr with sleep duration in cirrhosis. Further trace element-based therapy such as Zn supplementation may be novel approach to reverse this sleep problem.

RESUMO

OBJECTIVE: The prognostic value of serum ferritin remains elusive in the literature. We aimed to examine the association between serum ferritin and mortality risk in cirrhosis. METHODS: A total of 257 cirrhotic patients were recruited. The cut-off of serum ferritin was determined by X-tile. The Cox regression and Kaplan-Meier method were used. A 1:1 propensity score matching (PSM) was performed to diminish the impacts of selection bias and possible confounders. RESULTS: The difference regarding mortality was mostly significant for serum ferritin >158 ng/mL. Before PSM, serum ferritin >158 ng/mL was an independent predictor of mortality. However, the clinical relevance of high ferritin level for prognostication was blunted after PSM (survival rate: 86.8% vs 96.3%, P = .078). Cox regression indicated that model for end-stage liver disease remains only independent risk factor of 180-day mortality after PSM. CONCLUSION: Serum ferritin may not serve as an independent prognostic indicator of mortality risk in decompensated cirrhotic patients.
