Abstract
BACKGROUND Exercise, particularly resistance exercise, is beneficial for sarcopenia in patients with liver cirrhosis. However, the effects of exercise on events remain unclear. We aimed to examine the effects of exercise on serious events in patients with liver cirrhosis using a meta-analysis of randomized controlled trials (RCTs). METHODS A literature search was conducted in 2022. Eleven RCTs were selected for the meta-analysis (exercise group, n = 232; control group, n = 193). Serious events were defined as death or serious complications according to the original articles. A meta-analysis was performed using a random-effects model. The primary outcome was the incidence of serious events. RESULTS In the 11 RCTs, the incidence of serious events was 5.6% (13/232) and 12.3% (24/193) in the exercise and control groups, respectively. However, a meta-analysis demonstrated no significant difference in the incidence of serious events between the two groups (risk difference [RD] - 0.03, 95% confidence intervals (CI) - 0.07 to 0.02). In a stratification analysis based on a combination of aerobic and resistance exercise, five RCTs (n = 185) were enrolled. The incidence of serious events was 6.25% (7/112) and 24.7% (18/73) in the combination exercise and control groups, respectively. A meta-analysis demonstrated a significant reduction in the incidence of serious events in the combination exercise group compared with the control group (RD - 0.12; 95% CI - 0.21 to - 0.03). CONCLUSIONS Resistance exercise in combination with aerobic exercise reduces serious events in patients with liver cirrhosis. A combination of aerobic and resistance exercise may be beneficial to improve the prognosis of patients with liver cirrhosis.

Exercise training as an intervention for frailty in cirrhotic patients on the liver transplant waiting list: A systematic review. World J Hepatol 2023; 15:1153-1163. [PMID: 37970618 PMCID: PMC10642435 DOI: 10.4254/wjh.v15.i10.1153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 09/21/2023] [Accepted: 10/08/2023] [Indexed: 10/24/2023] Open
Abstract
BACKGROUND The existing literature suggests that exercise for cirrhotic patients is safe and favours significant improvement to their physical capacity. However, exercise training for this population and how to deliver activities, especially in severe stages of the disease and while waiting for a liver transplant (LT), remain undefined. AIM To review the existing exercise prescriptions for cirrhotic patients on the waiting list for LT, their results for frailty evolution and their effect on clinical outcomes. METHODS A systematic review was performed following the Preferred Reporting Review and Meta-Analysis guidelines and searching the PubMed, MEDLINE, and Scopus databases. The keyword "liver transplant" was used in combination with the free terms "frailty" and "exercise" for the literature review. Clinical studies that evaluated the effect of a regular training program, independent of supervision or the duration or intensity of physical exercise, in cirrhotic patients on the waiting list for LT were reviewed. The data on safe physical activity prescriptions following Frequency, Intensity, Time, and Type recommendations were extracted and summarised. RESULTS Nine articles met the inclusion criteria for this review. Various instruments for frailty assessment were used, frequently in combination. Five studies prescribed physical activity for patients, one in-person and four to be performed remotely and unsupervised. The remaining four studies only used a self-report instrument to assess the level of physical activity. None reported adverse events related to exercise training. The exercise frequency mainly varied from daily to a minimum of twice per week. The intensity depended on frailty and included increasing levels of activity. The type of exercise was predominantly a combination of aerobic and resistance training. The duration of exercise varied from 4 to 12 wk. Three articles evaluated the effect of the exercise program on clinical outcomes, reporting a reduction in 90-d readmission rates post-transplant and improved frailty scores, as well as improved survival of cirrhotic patients waiting for LT. CONCLUSION Routine frailty assessment is essential for this population. Although more robust evidence is required, the prescription of exercise is safe and can improve patients' functional capacity, improving pre- and post-LT outcomes.

Six-Minute walk distance predicts outcomes in liver transplant candidates. Liver Transpl 2023; 29:521-530.

Abstract
A 6-minute walk test is a simple tool for assessing submaximal exercise capacity. We sought to determine whether a 6-minute walk distance (6MWD) predicts outcomes in patients with cirrhosis. The Pulmonary Vascular Complications of Liver Disease 2 study is a multicenter, prospective cohort study that enrolled adults with portal hypertension during liver transplantation evaluation. We excluded subjects with an incident or prevalent portopulmonary hypertension. The 6-minute walk test was performed using standardized methods. Cox proportional hazards modeling and multivariable linear regression analysis were performed to determine the relationship between baseline 6MWD and outcomes. The study sample included 352 subjects. The mean 6MWD was 391±101 m. For each 50-meter decrease in 6MWD, there was a 25% increase in the risk of death (HR 1.25, 95% CI [1.11, 1.41], p < 0.001) after adjustment for age, gender, body mass index, MELD-Na, and liver transplant as a time-varying covariate. In a multistate model, each 50-meter decrease in 6MWD was associated with an increased risk of death before the liver transplant ( p < 0.001) but not after the transplant. 6MWD was similar to MELD-Na in discriminating mortality. Each 50-meter decrease in 6MWD was associated with an increase in all-cause ( p < 0.001) and transplant-free hospitalizations ( p < 0.001) in multivariable models for time-to-recurrent events. Shorter 6MWD was associated with worse Short Form-36 physical ( p < 0.001) and mental component scores ( p = 0.05). In conclusion, shorter 6MWD is associated with an increased risk of death, hospitalizations, and worse quality of life in patients evaluated for liver transplantation. The 6-minute walk distance may be a useful adjunct for risk assessment in patients undergoing liver transplant evaluation.

Effects of an active lifestyle on the physical frailty of liver transplant candidates. World J Transplant 2022; 12:365-377. [PMID: 36437844 PMCID: PMC9693895 DOI: 10.5500/wjt.v12.i11.365] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 08/26/2022] [Accepted: 10/18/2022] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Liver transplantation is the most important therapeutic intervention for end-stage liver disease (ELD). The prioritization of these patients is based on the model for end-stage liver disease (MELD), which can successfully predict short-term mortality. However, despite its great validity and value, it cannot fully incorporate several comorbidities of liver disease, such as sarcopenia and physical frailty, variables that can sufficiently influence the survival of such patients. Subsequently, there is growing interest in the importance of physical frailty in regard to mortality in liver transplant candidates and recipients, as well as its role in improving their survival rates.
AIM To evaluate the effects of an active lifestyle on physical frailty on liver transplant candidates.
METHODS An observational study was performed within the facilities of the Department of Transplant Surgery of Aristotle University of Thessaloniki. Twenty liver transplant candidate patients from the waiting list of the department were included in the study. Patients that were bedridden, had recent cardiovascular incidents, or had required inpatient treatment for more than 5 d in the last 6 mo were excluded from the study. The following variables were evaluated: Activity level via the International Physical Activity Questionnaire (IPAQ); functional capacity via the 6-min walking test (6MWT) and cardiopulmonary exercise testing; and physical frailty via the Liver Frailty Index (LFI).
RESULTS According to their responses in the IPAQ, patients were divided into the following two groups based on their activity level: Active group (A, 10 patients); and sedentary group (S, 10 patients). Comparing mean values of the recorded variables showed the following results: MELD (A: 12.05 ± 5.63 vs S: 13.99 ± 3.60; P > 0.05); peak oxygen uptake (A: 29.78 ± 6.07 mL/kg/min vs S: 18.11 ± 3.39 mL/kg/min; P < 0.001); anaerobic threshold (A: 16.71 ± 2.17 mL/kg/min vs S: 13.96 ± 1.45 mL/kg/min; P < 0.01); 6MWT (A: 458.2 ± 57.5 m vs S: 324.7 ± 55.8 m; P < 0.001); and LFI (A: 3.75 ± 0.31 vs S: 4.42 ± 0.32; P < 0.001).
CONCLUSION An active lifestyle can be associated with better musculoskeletal and functional capacity, while simultaneously preventing the evolution of physical frailty in liver transplant candidates. This effect appears to be independent of the liver disease severity.

Factors associated with early postoperative exercise tolerance after living-donor liver transplantation. Clin Transplant 2022; 36:e14800.

Abstract
BACKGROUND Physical dysfunction, including exercise intolerance, is a major factor for delayed societal reintegration for patients who underwent living-donor liver transplantation (LDLT). However, what may contribute to early postoperative physical function is not well known. The purpose of this study is to elucidate the perioperative factors affecting early posttransplant exercise intolerance. METHODS 103 consecutive patients who underwent LDLT were enrolled, and 68 patients were retrospectively analyzed. We examined the relationship between postoperative exercise tolerance evaluated by a 6-minute walking distance (6MWD) at discharge after surgery and demographic data, surgical information, preoperative physical function, clinical course, and the postoperative decline in physical function with univariate and multivariate analyses. RESULTS Almost all patients were discharged within 3 months after surgery. The postoperative 6MWD was 408 ± 94 m (68 [61-84]% of the predicted value), and patients who had a low %6MWD at discharge had significantly lower preoperative physical function than patients who had a high %6MWD at discharge (grip strength: 29.8 ± 8.9 kgf vs. 23.0 ± 8.8 kgf, P < .01, knee extensor strength: 138.9 ± 59.4 Nm vs. 95.2 ± 42.1 Nm, P < .01). Multivariate analysis revealed that preoperative knee extensor strength (standardized β = 0.35, P < .01) and first postoperative walking day (standardized β = -0.22, P = .04) were independently associated with the postoperative %6MWD. CONCLUSION These results suggest that maintaining preoperative muscle strength and allowing for early postoperative mobilization might help to enhance the recovery of physical function and facilitate the patient's social reintegration after LDLT.

Abstract
BACKGROUND Mobility affects the ability of patients to live independently post-discharge. This study aimed to identify factors affecting the achievement of independent walking in patients after living donor liver transplantation (LDLT). METHODS This retrospective cohort study involved 40 patients who had undergone LDLT for severe hepatic dysfunction (Child-Pugh class C) in the Department of Transplant Surgery of our hospital between January 2010 and October 2019 and received physiotherapy during hospital admission. To identify factors associated with independent walking, we classified patients based on their ability to walk independently. We performed multiple logistic regression analyses with the patients' attributes, biochemical tests, and physical function, considering the achievement or non-achievement of independent walking as dependent variables, and factors that were significantly different between the 2 groups in the univariate analysis (P < .05) as independent variables, after adjusting for age, sex, and body mass index. Moreover, we calculated cutoff values from the receiver operating characteristic (ROC) curves. RESULTS All patients suffered from severe hepatic dysfunction (Child-Pugh class C). The mobility Functional Independence Measure score following rehabilitation was positively correlated with the psoas major muscle index within 1 month after LDLT and at the beginning of physiotherapy. The only factor associated with achieving independent walking at the end of physiotherapy (on discharge) was the psoas major muscle index within 1 month of LDLT (odds ratio = 35.03, P < .05), and its cutoff value, calculated from the ROC curves curve, was 4.46. CONCLUSION Psoas major skeletal muscle mass is a reliable index for independent walking after LDLT.

Abstract
Frailty manifesting as sarcopenia is an independent risk factor for mortality in cirrhosis, and often presents in low model for end-stage liver disease (MELD) patients. Its etiology is multifactorial, but key physiologic changes culminate in altered energy utilization in the fasting state, preferentially utilizing muscle amino acids for gluconeogenesis thereby promoting sarcopenia. Hyperammonemia alters the circulating amino acid profile, diminishing pro-muscle branched-chain amino acids like leucine. The metabolic syndrome worsens sarcopenia through multi-tissue insulin resistance. Alcohol also exacerbates sarcopenia as a direct muscle toxin and inhibitor of growth signaling. Therapy is aimed at alcohol cessation, frequent high-protein meals, branched-chain amino acid supplementation, and diminished time spent fasting. Moderate exercise can improve muscle mass and muscle quality, though precise exercise regimens have not yet been explicitly determined. Studies are ongoing into the effects of myostatin antagonists and insulin sensitizers. The Liver Frailty Index can predict patients most at risk of poor outcome and should be considered in the management of all cirrhotic patients. Specialty testing like dual-energy X-ray absorptiometry (DEXA) scanning and cross-sectional estimates of muscle mass are areas of active research and may play a future role in clinical risk-stratification.

Abstract
INTRODUCTION Studies examining impairment, disability and social disadvantage of patients with chronic viral hepatitis B (CHB) are scarce and present conflicting conclusions. AIM To assess the deficiency, incapacity, and social disadvantage of patients with CHB. METHODS This is a project of a case-control study with two age-matched groups. Cases (n=27) will be untreated patients with a CHB. Controls (n=27) will be healthy participants. The following data will be collected: deficiency [anthropometric, biochemical (renal and hepatic functions, lipid balance, and inflammatory markers), haematological, virological, handgrip-strength, and spirometric data], incapacity [6-min walk distance, number of stops, oxy-haemoglobin saturation, dyspnoea (visual analogue scale), heart-rate, and blood-pressure] and social disadvantage ["chronic liver disease" and physical-activity questionnaires]. Each spirometric data < lower-limit-of-normal will be considered abnormal. A handgrip-strength <26 kg (male) or <16 kg (female) will be considered low. The signs of walking intolerance will be: stop during the walk, 6-min walk distance ≤ lower-limit-of-normal, dyspnoea at the end of the walk> 5/10, drop in oxy-haemoglobin saturation >5 points, heart-rate at the end of the walk ≤60%. A total physical-activity score <9.42 will classify the participant as sedentary. EXPECTED RESULTS Compared with controls, cases will have a marked alteration of submaximal aerobic data. These alterations will worsen quality-of-life and may be related to muscle and/or spirometric abnormalities, and supported by systemic inflammation and high viral load.

Abstract
Background Physical inactivity and sarcopenia are two important predictors associated with increased morbidity and mortality in patients with cirrhosis. At present, the benefit of a home-based exercise training program is not well established in cirrhotic patients. The main objective of this study was to evaluate the effect of a 12-week home-based exercise training program on aerobic capacity in cirrhotic patients. Methods This is a randomized controlled study. Patients with compensated cirrhosis were randomized by a block of 4 with concealed allocation to the home-based exercise training (n = 20) or control (n = 20). Both groups received protein supplementation (9 g/day) for 12 weeks. The home-based exercise training program included several aerobic/isotonic moderate-intensity continuous training exercises for 40 min per session, at least four times a week, with a total duration of 12 weeks. The heart rate was continuously monitored using a Garmin® watch. In the control group, patients received exercise instruction without active encouragement and continuous monitoring. The primary outcome was a change in the 6-min walk test from baseline. Secondary outcomes were the difference in thigh muscle thickness, liver stiffness, spleen stiffness, and quality of life. Results A total of 40 patients were enrolled prospectively. The mean age was 56.3 ± 7.8 years, with a male predominance of 65%. The mean body mass index was 25.23 ± 3.0 kg/m2, and all were Child–Pugh A. Chronic hepatitis B or C was the primary cause of cirrhosis. The baseline values were a 6-min walk test of 475 ± 70 m, liver stiffness of 15.3 ± 9.3 kPa, spleen stiffness of 29.8 ± 21.7 kPa, and thigh muscle thickness (average compression index) of 0.64 ± 0.2 cm/m2. All baseline characteristics between the two groups were not different except the mean muscle mass which was significantly higher in the home-based exercise training group (p = 0.03, 95% CI 0.01 to 0.17). At the end of the study, no significant difference in the 6-min walk test was observed (p = 0.36, 95% CI −15.5 to 41.7). Liver stiffness measurement significantly improved in both groups, but no significant difference between groups was demonstrated (p = 0.77, 95% CI −1.3 to 1.8). Thigh muscle thickness was not different between groups. The fatigue domain of the quality of life index was significantly improved in the home-based exercise training group compared with the control group (p = 0.05, 95% CI 0.00 to 0.67). No adverse events occurred in a home-based exercise training program. Conclusions A 12-week moderate-intensity home-based exercise training program in compensated cirrhotic patients significantly improved the fatigue domain of the quality of life index without an increase in adverse events. However, no benefit in terms of aerobic capacity, thigh muscle mass, liver stiffness, and spleen stiffness was demonstrated.

Abstract
BACKGROUND Patients with cirrhosis are at risk of cirrhotic cardiomyopathy, with resulting cardiac dysfunction and exercise limitations. Six minute walking test (6MWT) assesses functional status and predicts morbidity and mortality in cardiopulmonary diseases.
AIM To determine if it associates with mortality by analyzing 6MWT performance in patients with liver cirrhosis.
METHODS A cohort of 106 cirrhotic patients was evaluated in the outpatient setting with echocardiogram and 6MWT and follow up for one year to document hepatic decompensation and mortality. The distance in meters was recorded at the end of 6 min (6MWD).
RESULTS This cohort had a mean age of 51 years and 56% male; patients were staged as Child A in 21.7%, B 66% and C 12.3%. Walk distance inversely correlated with Child scores, and was significantly reduced as Child stages progresses. Patients who died (10.4%) showed shorter mean 6MWD (P = 0.006). Low 6MWD was an independent predictor of mortality (P = 0.01).
CONCLUSION 6MWT is a noninvasive inexpensive test whose result is related to Child scores and mortality. It is useful to identify patients with liver cirrhosis at high risk of mortality for closer monitoring and potential early intervention.

Abstract
Reduction in muscle mass is a highly prevalent phenomenon in cirrhosis and is now well-documented to be associated with significant morbidity and mortality. Research into muscle loss in cirrhosis remains limited by an ongoing poor understanding of its relationship with muscle function, physical activity, and aerobic capacity. Alterations in exercise physiology have been documented in studies of individuals with cirrhosis that provide important information on physical function that is not captured by simple quantification of muscle mass. Despite expert consensus recommending regular exercise in end-stage liver disease to maintain muscle mass and function, there is little evidence guiding clinicians as to which form of exercise or delivery mechanism is most effective. It also remains unproven whether any specific intervention can alter clinically relevant outcomes. This review article summarizes the available literature regarding the changes in exercise physiology observed in cirrhosis, the associated impact on physical capacity, and the results of existing trials that examine the potential benefits of exercise delivery in patients with cirrhosis, particularly pertaining to their impact on exercise physiology.

Abstract
Frailty has emerged as a powerful predictor of clinical outcomes (e.g., decompensation, hospitalization, mortality) in patients with end-stage liver disease (ESLD). It is therefore of paramount importance that all patients with ESLD undergo an assessment of frailty, to support life and death decision making (i.e., candidacy for critical care, transplantation) and aid with prioritization of evolving prehabilitation services (i.e., nutrition, physiotherapy, psychotherapy). This article aims to provide a practical overview of the recent advances in the clinical, radiological, and remote assessment tools of the frail patient with ESLD. Historically, clinicians have incorporated an assessment of frailty using the "end-of-the-bed test" or "eyeball test" into their clinical decision making. However, over the last decade, numerous nonspecific and specific tools have emerged. The current evidence supports the use of a combination of simple, user-friendly, objective measures to first identify frailty in ESLD (notably Clinical Frailty Scale, Liver Frailty Index), followed by a combination of serial tools to assess specifically sarcopenia (i.e., muscle ultrasound), physical function (i.e., chair stands, hand grip strength), functional capacity (i.e., 6-minute walk test), and physical disability (i.e., activities of daily living).

Abstract
We investigated the prevalence of spirometric restriction in liver transplantation (LT) candidates and the clinical impacts of restriction. We performed a cross-sectional study within the Pulmonary Vascular Complications of Liver Disease 2 (PVCLD2) study, a multicenter prospective cohort study of patients being evaluated for LT. Patients with obstructive lung disease or missing spirometry or chest imaging were excluded. Patients with and without restriction, defined as a forced vital capacity (FVC) <70% predicted, were compared. Restriction prevalence was 18.4% (63/343). Higher Model for End-Stage Liver Disease-sodium score (odds ratio [OR], 1.06; 95% confidence interval [CI], 1.02-1.11; P = 0.007), the presence of pleural effusions (OR, 3.59; 95% CI, 1.96-6.58; P < 0.001), and a history of ascites (OR, 2.59; 95% CI, 1.26-5.33; P = 0.01) were associated with the presence of restriction, though one-third with restriction had neither pleural effusions nor ascites. In multivariate analysis, restriction was significantly and independently associated with lower 6-minute walk distances (least squares mean, 342.0 [95% CI, 316.6-367.4] m versus 395.7 [95% CI, 381.2-410.2] m; P < 0.001), dyspnea (OR, 2.69; 95% CI, 1.46-4.95; P = 0.002), and lower physical component summary Short Form 36 scores indicating worse quality of life (least squares mean, 34.1 [95% CI, 31.5-36.7] versus 38.2 [95% CI, 36.6-39.7]; P = 0.004). Lower FVC percent predicted was associated with an increased risk of death (hazard ratio, 1.16; 95% CI, 1.04-1.27 per 10-point decrease in FVC percent predicted; P = 0.01). Restriction and abnormal lung function are common in LT candidates; can be present in the absence of an obvious cause, such as pleural effusions or ascites; and is associated with worse exercise capacity, quality of life, and survival.

Abstract
Background/Aims Children with Down's syndrome are often considered to be sedentary and less likely to engage in the recommended levels of physical activity. The aim of this study was to compare the walking capacity of male children with Down's syndrome with a group of typically healthy age-matched children in Saudi Arabia. Methods A total of 78 male children aged from 8 to 12 years participated in the study. They were divided into two groups. The first group comprised 37 male children with Down's syndrome, recruited from the Down's Syndrome Charitable Association and Al-Nahda Schools. The second group comprised 41 male children with typical development, who were recruited from regular schools in the same region. Walking capacity was measured with the 6-Minute Walk Test. Results The children with Down's syndrome had significantly reduced 6-Minute Walk Distance scores than children with typical development. Conclusions There is a need to establish good strategies, programmes and early interventions designed to promote physical activity levels and improve the quality of life for people with Down's syndrome.

Abstract
Sarcopenia is a pathological condition affecting the development and progression of NAFLD. Urinary levels of titin-N fragment, a biomarker reflecting muscle damage, were measured in NAFLD subjects, and analyzed in a retrospective manner for possible correlations with NAFLD pathophysiology to assess their clinical relevance. This study enrolled 153 NAFLD subjects and 100 subjects without NAFLD, obesity or diabetes mellitus (non-NAFLD). NAFLD subjects had more decreased knee extension strength. NAFLD subjects had greater subcutaneous fat thickness and echo intensity (brightness) of the rectus femoris muscle on ultrasound images; higher levels of the intra- and extra-myocellular lipids (IMCL, EMCL) using 1H-MRS. Urinary titin-N fragment levels were increased with increasing age but not different between males and females. NAFLD subjects had higher titin-N fragment levels than non-NAFLD subjects. The levels were negatively correlated with skeletal muscle mass and knee extension strength and positively correlated with muscle echo intensity, EMCL, and liver fibrosis scores (NAFLD fibrosis score, FIB-4 index). Multivariate analysis revealed that factors affecting the levels were skeletal mass index, leg skeletal muscle mass, liver stiffness, and NAFLD fibrosis score. Urinary levels of titin-N fragment reflected skeletal muscle deterioration and functional decline, and was closely associated with hepatic pathological conditions in NAFLD subjects.

Abstract
BACKGROUND Fatigue is highly prevalent in end stage liver disease, the studies about its association with exercise capacity in cirrhotic patients before liver are scarse. OBJECTIVE In this study, we evaluated fatigue in 95 in end stage liver disease patients awaiting transplantation, compared to healthy volunteers, and tested the association between exercise capacity and fatigue. METHODS Cross-sectional study of patients with chronic liver disease treated at a referral center in Fortaleza, Brazil. Fatigue was quantified with the Fatigue Severity Scale. The patients were submitted to the 6-min walk test, the 6-min step test, the Hospital Anxiety and Depression Scale, C-reative protein measurement and hematocrit count, measurement of dyspnea among other tests. Fatigue data were obtained from healthy individuals for comparison with patients. RESULTS The mean age of patients was 45.9±12.3 years, and 53.7% were male. Fatigue, anxiety and depression levels were higher among end stage liver disease patients than among controls. A negative correlation was observed between 6 min step test and Fatigue Severity Scale score (r= -0.2; P=0.02) and between hematocrit count and Fatigue Severity Scale score (r= -0.24; P=0.002). Dyspnea on the Borg scale and fatigue were positively correlated (r=31; P=0.002). In the multivariate analysis, low 6-min step test values and high levels of dyspnea were associated with fatigue. CONCLUSION Fatigue was more prevalent and severe in end stage liver disease patients than in healthy controls. Low 6MST values and high levels of dyspnea were associated with fatigue in this scenario.

Abstract
In this study we investigated the impact of rs2596542A/G single nucleotide polymorphism (SNP) in the major histocompatibility complex class I chain-related sequence A (MICA) gene on HCV-induced hepatocellular carcinoma (HCC) susceptibility in a Brazilian population. In total, 252 HCV-infected patients (98 with HCV-induced HCC and 154 non-malignant HCV-induced liver cirrhosis) were enrolled and 98 healthy control subjects (negative anti-HCV). The MICA rs2596542 SNP genotypes were determined by real-time PCR assay. No differences in MICA genotype frequencies between HCV-induced cirrhosis patients and controls were observed. However, genotype frequencies of rs2596542A/G SNP were statistically different between HCV-induced HCC patients and controls (p = 0.048), and also between HCC and HCV-induced cirrhosis patients (p = 0.039). The highest frequency of the rs2596542AA genotype was observed in HCC patients (31.6%) when compared with HCV-induced cirrhosis patients (18.8%) and healthy controls (19.4%). Also, rs2596542AA genotype carriers have an increased risk for HCC when compared to HCV-induced cirrhosis status [odds ratio (OR) = 1.99; 95% confidence interval (CI) = 1.06-3.74, p = 0.020)] and healthy individuals (OR = 1.92, 95% CI = 1.00-3.70, p = 0.049). Taken together our study suggest that MICA rs2596542 SNP impacts HCV-induced HCC susceptibility suggesting that genetic variants in MICA are of clinical relevance to hepatocarcinogenesis by impacting host immune response in chronic HCV infection.

Abstract
BACKGROUND/AIMS Functional impairment is common among cirrhotic patients with refractory ascites, and improvement in functional impairment is an expected issue after paracentesis. The six-minute walk test (6MWT) is considered an objective test for functional activity. No published data have evaluated the 6MWT among cirrhotic patients with refractory ascites before and after large-volume paracentesis. The research aim was to assess the feasibility of performing the 6MWT among cirrhotic patients who had refractory ascites before and after large-volume paracentesis. MATERIALS AND METHODS Thirty-one cirrhotic inpatients with refractory ascites were subjected to pulmonary function tests (forced expiratory volume in one second [FEV1], forced vital capacity [FVC], FEV1/FVC) and diffusion lung capacity for carbon monoxide (DLCO) before and 48 h after therapeutic large-volume paracentesis. Dyspnoea as assessed by the Borg scale and functional capacity as assessed by the 6MWT were also evaluated. RESULTS Prior to paracentesis, the mean values of FVC and FEV1 were lower than the predicted values, and a significant increase was observed after paracentesis. There was improvement in the mean DLCO values after paracentesis (P < 0.05). Regarding the 6MWT, significant increases in the walked distance (6MWD) (310.7 ± 73 vs. 348.7 ± 72.3 m) and oxygen saturation after paracentesis (P = 0.001) were observed. Significant improvement in the dyspnoea scale also occurred after paracentesis (P = 0.001). A significant positive correlation between the 6MWD before paracentesis and serum albumin levels was demonstrated (r = 0.373, P = 0.039). CONCLUSION We found a decrease in pulmonary function and the 6MWD in patients who had refractory ascites, which improved significantly following large-volume paracentesis. The 6MWT is useful in detecting impaired functional capacity among cirrhotic patients.

Progressive reduction in skeletal muscle mass to visceral fat area ratio is associated with a worsening of the hepatic conditions of non-alcoholic fatty liver disease.

[PMID: 31114278 PMCID: PMC6489648 DOI: 10.2147/dmso.s185705] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2018] [Accepted: 03/07/2019] [Indexed: 12/25/2022] Open
Abstract
Background: Deceased muscle mass combined with increased visceral fat mass is reportedly linked to a higher risk of worsening the hepatic conditions of non-alcoholic fatty liver disease (NAFLD). Objective: The aim of this study was conducted in a retrospective manner to investigate whether longitudinal changes in skeletal muscle mass to visceral fat area ratio (SV ratio), an index of sarcopenic obesity, are influential on the hepatic conditions and pathophysiology of NAFLD during the clinical course. Design: The association of SV ratio with hepatic conditions and pathophysiology was evaluated longitudinally for 2-5.5 years (median 4.1 years) in 92 patients with NAFLD (36 men and 56 women; 17-78 years). The subjects were divided into three groups according to the change in their SV ratio: improved, stable, or worsened, and the changes in parameters associated with NAFLD were compared among the groups. Results: In the group with a worsened SV ratio, visceral fat area increased (122±30-138±30 cm2; mean ± SD), whereas total muscle mass decreased (26.5±6.1-25.9±5.9 kg), which was especially noticeable in the lower extremities (14.8±3.3-14.3±3.1 kg). In accordance with the change of body composition, transient elastography showed higher levels of liver stiffness (7.7±5.4-9.0±6.0 kPa) and fat accumulation (265±43-293±48 dB/m). There were also higher levels of fasting plasma glucose (115±29-126±40 mg/dL) and HbA1c (6.0±1.1-6.3±1.0%). In contrast, deterioration in these parameters did not occur in the groups with improved or stable SV ratios. Conclusion: Collectively, a progressive reduction in skeletal muscle mass accompanied by an increase in visceral fat mass during the clinical course of NAFLD is associated with a worsening of the hepatic conditions, fat accumulation and progression of fibrosis.

Abstract
Portopulmonary hypertension (PoPH) is a form of pulmonary arterial hypertension (PAH) that can develop as a complication of portal hypertension. Treatment of PoPH includes PAH-specific therapies, and in certain cases, such therapies are necessary to facilitate a successful liver transplantation. A significant number of barriers may limit the adequate treatment of patients with PoPH and explain the poorer survival of these patients when compared to patients with other types of PAH. Until recently, only one randomized controlled trial has included PoPH patients, and the majority of treatment data have been derived from relatively small observational studies. In the present article, we review some of the barriers in the treatment of patients with PoPH and implications for liver transplantation.

Abstract
Physical inactivity, sarcopenia, and frailty are highly prevalent, independent predictors of morbidity and mortality in patients with cirrhosis. Across a range of chronic diseases, exercise training is a key recommendation supported by guidelines and, for some conditions, even by governmental funding of exercise programmes. Consistent with the broader chronic disease literature, the evidence for a benefit of exercise in cirrhosis is promising. Several small trials have reported significant improvements in muscle health (mass, strength, functional capacity), quality of life, fatigue, and reductions in the hepatic venous pressure gradient, without adverse events. With strong emerging evidence surrounding the substantial risks of sarcopenia/frailty and our first-hand experiences with liver pre-transplant exercise programmes, we contend that routine patient care in cirrhosis should include an exercise prescription. Some clinicians may lack the resources and necessary background to translate the existing evidence into a practicable intervention. Our team, comprised of physiotherapists, exercise physiologists, hepatologists, transplant specialists, and knowledge translation experts from six North American centres, has distilled the essential background information, tools, and practices into a set of information ready for immediate implementation into clinics ranging from a family practice setting to specialty cirrhosis clinics. Augmenting the rationale and evidence are supplementary materials including video and downloadable materials for both patients and the physician. Supporting the exercising patient is a section regarding information about nutrition, providing practical tips suitable for all patients with cirrhosis.

Abstract
INTRODUCTION We sought to describe: 1) The influence of orthotopic liver transplantation (OLT) on exercise capacity, pulmonary function and respiratory muscle strength after surgery, 2) The relationship between exercise capacity and symptoms of anxiety and depression. MATERIAL AND METHODS This is a prospective follow up study conducted with patients submitted to OLT. All patients were assessed before and 1 month after surgery through measurements: six minute walk test (6MWT), 6 min step test (6MST) and HADS (Hospital Anxiety and Depression Scale). FEV1% (forced expiratory volume), maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) were measured in the pre-operative and on 1st, 3rd, 5th day and 1 month after surgery. RESULTS In 77 patients , 6MWD improved 20.2 m (95%CI 8.1-32.3) and 6MST improved 7.8 steps after surgery (95%CI 3.9-11.6). Change in 6 MWD and 6 MST did not correlated with change HADS. The FEV1% at each time point were 88.8 ± 21.3 before surgery, 32.9 ± 9.9 on 1st day, 39.6 ± 11.5 on 3rd day, 46 ± 12.1 on 5th day and 86.6 ± 21.1 one month after surgery. MIP and MEP values at each time point were -67.4 ± 23.2 and 79.7 ± 26 before surgery, -30.8 ± 12.3 and 36.4 ± 15.4 on 1st day, -38.6 ± 14.1 and 43.8 ± 17 on 3rd day, -45.8 ± 15.9 and 49.7 ± 18.7 on 5th day and -67.1 ± 29.4 and 80.9 ± 23.9 one month after surgery. CONCLUSION Exercise capacity was modestly increased after OLT without any correlation with symptoms of anxiety and depression. Pulmonary function and respiratory muscle strength decreased immediately after liver transplantation, and progressively recovered, returning to baseline values after 1 month.

Abstract
PURPOSE OF REVIEW The purpose of this review is to discuss the current evidence regarding the impact of sarcopenia on patients with cirrhosis awaiting liver transplantation and to determine if its presence should be considered a criterion for expedited transplantation or a contraindication for transplantation. RECENT FINDINGS Sarcopenia is a negative predictor of survival in patients on a waiting list and after liver transplant. The gut-liver axis and the liver-muscle axis have been explored to understand the complex pathophysiology of sarcopenia. Sarcopenia is a frequent finding in patients with cirrhosis. The diagnosis is ideally based on cross-sectional image analysis (CT or MRI) and treatment consists of optimization of caloric and protein intake. To date, prioritizing tools for liver transplantation have not included nutrition or sarcopenia parameters. Patients with a low Model for End-Stage Liver Disease (MELD) or MELD-Na score and sarcopenia would benefit from prioritization for transplant in order to reduce time on waiting list and therefore mortality.

Abstract
OBJECTIVE The aim is assess, compare, and correlate maximal oxygen consumption (VO2max. ), functional capacity and quality of life in cirrhotic patients with hepatitis C virus (HCV) and in healthy individuals. METHODS This case-control study included 36 participants (18 patients with HCV cirrhosis and 18 healthy individuals) matched for sex and age. VO2max was assessed using ergospirometry with an incremental load test on a cycloergometer. Functional capacity was measured by a 6-min walk test (6WT), and quality of life was assessed using the 36-Item Short-Form Health Survey (SF-36). RESULTS Both the cirrhotic group and the control group had similar results for sex (44.4% male) and age (55.6 ± 8.31 and 55.2 ± 8.85 years, respectively). The cirrhotic group scored lower in all domains of the SF-36, on the VO2max test (cirrhotic group 16.2 [11.6-18.6] ml/kg/min; control group 19.9 [16.28-26.9]; p = 0.007) and on the 6WT (cirrhotic group 521.5 [476.25-544.75] m; control group 618.0 [570.75-643.75] m; p = 0.0001). Correlations were found between the 6WT and the VO2max (r = 0.801, p < 0.0001) and between the 6WT and quality of life (SF-361-functional capacity domain; r = 0.552, p = 0.018) only in the cirrhotic group. CONCLUSION Patients with cirrhosis due to HCV show changes in VO2max and in functional capacity, which have a significant impact on their quality of life.

Abstract
INTRODUCTION A wide variety of pulmonary conditions are found in cirrhotic patients and may compromise the pleura, diaphragm, parenchyma, and pulmonary vasculature, influencing the results of liver transplantation. OBJECTIVE To evaluate the pulmonary function (lung capacities, volumes, and gasometric study) of patients with liver cirrhosis awaiting liver transplantation. PATIENTS AND METHODS Cirrhotic patients, subdivided into 3 groups stratified by liver disease severity using the Child-Pugh-Turcotte score, were compared with a control group of healthy volunteers. In spirometry, the parameters evaluated were total lung capacity, forced volume in the first second, and the relationship between forced volume in the first minute and forced vital capacity. Blood gas analysis was performed. In the control group, arterial oxygenation was evaluated by peripheral oxygen saturation by pulse oximetry. RESULTS Of the 55 patients (75% men, 51 ± 12.77 years), 11 were Child A (73% men, 52 ± 14.01 years), 23 were Child B (75% men, 51 ± 12.77 years), and 21 were Child C (95% men, 50 ± 12.09 years). The control group had 20 individuals (50% men, 47 ± 8.15 years). Pulmonary capacities and volumes by the parameters evaluated were within the normal range. Arterial blood gas analysis detected no hypoxemia, but a tendency to low partial gas pressure was noted. CONCLUSION In this population of cirrhotic patients the parameters of spirometry were normal in relation to the lung capacities and volumes in the different groups. No hypoxemia was detected, but a tendency to hypocapnia in the blood gas was noted.

Abstract
Multivisceral transplantation is the treatment for multiple abdominal organ failure. The patient experiences reduced food intake and absorption of nutrients, contributing to weight loss and decreased muscle mass, reducing functional capacity. A physical and nutritional rehabilitation program based on adequate caloric intake associated with supervised physical exercise seems to support a gain of muscle mass, re-establishing its capacity and functional independence. A rehabilitation program was carried out, consisting of low-intensity aerobic exercise on treadmill, exercises of global strengthening (50% of 1 maximum repetition [1RM], with progressive increase), and nutritional monitoring (oral hypercaloric diet, hyperproteic supplementation daily and after exercise). Initial and final evaluation included weight, muscle mass index, brachial circumference (BC), tricipital cutaneous fold (TCF), hand grip strength (HGS), 6-minute walk test (6MWT), 1RM, vital capacity (VC), and respiratory muscle strength. After the program, functional capacity was evaluated through the 6MWT (92%), 1RM test, VC (55%), respiratory muscle strength, HGS at 5 kg, weight gain (4.75%), increase of BC in 2 cm, and TCF in 2 mm. The program contributed to functional independence, improved quality of life, and social reintegration, suggesting the importance of a supervised physical activity program associated with adequate nutritional intake after multivisceral transplantation.

Abstract
BACKGROUND Not only obesity but also sarcopenia is associated with NAFLD. The influence of altered body composition on the pathophysiology of NAFLD has not been fully elucidated. The aim of this study is to determine whether skeletal muscle mass to visceral fat area ratio (SV ratio) affects NAFLD pathophysiology. METHODS A total of 472 subjects were enrolled. The association between SV ratio and NAFLD pathophysiological factors was assessed in a cross-sectional nature by stratification analysis. RESULTS When the SV ratio was stratified by quartiles (Q 1-Q 4), the SV ratio showed a negative relationship with the degree of body mass index, HOMA-IR, and liver stiffness (Q 1, 8.9 ± 7.5 kPa, mean ± standard deviation; Q 2, 7.5 ± 6.2; Q 3, 5.8 ± 3.7; Q 4, 5.0 ± 1.9) and steatosis (Q 1, 282 ± 57 dB/m; Q 2, 278 ± 58; Q 3, 253 ± 57; Q 4, 200 ± 42) measured by transient elastography. Levels of leptin and biochemical markers of liver cell damage, liver fibrosis, inflammation and oxidative stress, and hepatocyte apoptosis were significantly higher in subjects in Q 1 than in those in Q 2, Q 3, or Q 4. Moreover, fat contents in femoral muscles were significantly higher in subjects in Q 1 and the change was associated with weakened muscle strength. In logistic regression analysis, NAFLD subjects with the decreased SV ratio were likely to have an increased risk of moderate-to-severe steatosis and that of advanced fibrosis. CONCLUSIONS Decreased muscle mass coupled with increased visceral fat mass is closely associated with an increased risk for exacerbating NAFLD pathophysiology.

Abstract
Chronic liver disease has been associated with pulmonary dysfunction both before and after liver transplantation. Post-liver transplantation pulmonary complications can affect both morbidity and mortality often necessitating intensive care during the immediate postoperative period. The major pulmonary complications include pneumonia, pleural effusions, pulmonary edema, and atelectasis. Poor clinical outcomes have been known to be associated with age, severity of liver dysfunction, and preexisting lung disease as well as perioperative events related to fluid balance, particularly transfusion and fluid volumes. Delineating each and every one of these pulmonary complications and their associated risk factors becomes paramount in guiding specific therapeutic strategies.

Abstract
PURPOSE To determine whether the 6-minute walk test (6MWT) is a predictor of peak oxygen uptake ((Equation is included in full-text article.)O2) in patients with idiopathic pulmonary arterial hypertension (IPAH). METHODS A total of 157 patients treated for IPAH completed a 6MWT in accordance with American Thoracic Society standards. Heart rate, pulse oximetry, and Borg rating of perceived exertion were determined at baseline and posttest. A cardiopulmonary exercise test (CPET) was performed on a cycle ergometer using a ramp protocol. Participants were stratified post hoc by age into 3 groups: children (n = 26), adolescents (n = 49), and adults (n = 82). Multiple linear regression analysis was performed to predict peak (Equation is included in full-text article.)O2 from the 6MWT. RESULTS The regression equation generated for the children was the only model to strongly predict peak (Equation is included in full-text article.)O2 (r = 0.87; P < .001). Similar models for adolescent (r = 0.59; P < .001) and adult groups (r = 0.68; P < .001) did not achieve the same level of correlation. CONCLUSION Six-Minute Walk Test was able to accurately predict peak (Equation is included in full-text article.)O2 in children (6-12 years) with IPAH; however, the model was weaker for predicting peak (Equation is included in full-text article.)O2 in older populations. These findings suggest that 6MWT may be as valid a test for predicting peak (Equation is included in full-text article.)O2 in children with IPAH as CPET measured peak (Equation is included in full-text article.)O2. In older IPAH populations, CPET is the only reliable method for the evaluation of peak (Equation is included in full-text article.)O2.

Abstract
Cirrhosis is the most common indication for liver transplantation (LT) worldwide. Malnutrition is present in at least two-thirds of patients with cirrhosis awaiting LT. It negatively impacts survival, quality of life, and the ability to respond to stressors, such as infection and surgery. Muscle wasting or sarcopenia is the most objective feature of chronic protein malnutrition in cirrhosis, and this condition is associated with increased morbidity and mortality before and after LT. In addition to its objectivity, muscularity assessment with cross-sectional imaging studies is a useful marker of nutritional status in LT candidates, as sarcopenia reflects a chronic decline in the general physical condition, rather than acute severity of the liver disease. Despite the high prevalence and important prognostic role, malnutrition and sarcopenia are frequently overlooked because standards for nutritional assessment are lacking and challenges such as fluid retention and obesity are prevalent. In this review, current diagnostic methods to evaluate malnutrition, including muscle abnormalities in cirrhosis, are discussed and current knowledge regarding the incidence and clinical impact of malnutrition in cirrhosis and its impact after LT are presented. Existing and potential novel therapeutic strategies for malnutrition in cirrhosis are also discussed, emphasizing the treatment of muscle wasting in the LT candidate in an effort to improve survival while waiting for LT and to reduce morbidity and mortality after LT.Liver Transplantation 23 1451-1464 2017 AASLD.

Abstract
Purpose of Review Nutritional status in patients with cirrhosis is very frequently associated with macro- and micronutrient deficiencies. Cirrhosis itself is the cause of malnutrition and nutritional deficiencies but these conditions have to be identified and addressed properly as they can worsen the prognosis of cirrhosis. The goals of this review are to 1) identify and describe the challenges associated with nutritional assessment in cirrhosis and 2) describe recent advancements when using clinical, laboratory, and instrumental tools in the evaluation of malnourished patients with liver diseases. Recent Findings The most promising tools for nutritional assessment in cirrhosis include the evaluation of body composition with phase angle obtained by bioelectrical impedance analysis, computed tomography transverse images at the level of third lumbar vertebra. The Royal-Free Hospital global assessment algorithm appears to be helpful but needs further validation. Summary Nutritional assessment in cirrhosis is challenging as several factors, including edema, can interfere with it and because of lack of a validated gold standard. Regardless, nutritional assessment methods have been developed in recent years and should gain relevance in the clinical practice.

Abstract
AIMS Sarcopenia and physical disability assessed by a 6-min walking test (6MWT) are associated with poor prognosis of patients with chronic liver disease (CLD). However, CLD patients with hepatocellular carcinoma (HCC) mostly rest in bed during hospitalization. We aimed to investigate the effects of therapeutic exercise on liver function, 6MWT, and skeletal muscle mass during HCC treatment in patients with CLD. METHODS We enrolled 54 CLD patients with HCC (median age, 76 years). During hospitalization, patients performed a combination of stretching, strength training, balance practice, and endurance training (2.5-4 metabolic equivalents/20 min/day). Primary outcomes were changes from admission to discharge in Child-Pugh class, 6MWT, and skeletal muscle mass. Furthermore, factors associated with skeletal muscle atrophy were analyzed by a decision-tree analysis. RESULTS Exercise did not worsen the Child-Pugh class. On discharge, the 6MWT ambulation distance was maintained, and heart rate variability during the 6MWT was significantly improved compared to that on admission (area under the curve 50.3 vs. 39.0 arbitrary units; P = 0.0027). Although skeletal muscle mass was significantly reduced (20.6 kg vs. 20.0 kg, P = 0.0301), branched-chain amino acid (BCAA) treatment was identified as the most distinguishable factor for minimizing muscle mass atrophy (-1.1 kg vs. -0.5 kg/hospitalization). CONCLUSIONS Therapeutic exercise improved physical ability without worsening liver function during hospitalization for HCC treatment in CLD patients. Although exercise did not completely prevent skeletal muscle atrophy, BCAA treatment minimized the skeletal muscle atrophy. Thus, exercise with BCAA treatment may be important for the management of CLD patients with HCC.

Effects of home-based exercise and branched-chain amino acid supplementation on aerobic capacity and glycemic control in patients with cirrhosis. Hepatol Res 2017; 47:E193-E200. [PMID: 27219825 DOI: 10.1111/hepr.12748] [Citation(s) in RCA: 47] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2015] [Revised: 05/12/2016] [Accepted: 05/17/2016] [Indexed: 12/13/2022]
Abstract
AIM The aim of the current study is to examine whether home-based step exercise at anaerobic threshold (AT) and branched-chain amino acid (BCAA) supplementation improve aerobic capacity, ectopic fat in liver and muscle, and glycemic control in patients with liver cirrhosis. METHODS Six female patients with compensated liver cirrhosis received oral BCAA and were instructed to undertake bench step exercises at an intensity that corresponded to AT, with a goal of performing 140 min of exercise per week at home for 12 months. Fat deposition in liver (liver to spleen ratio) and intramuscular adipose tissue content were assessed at baseline and after 6 and 12 months by computed tomography. Glycemic control indices (homeostasis model assessment of insulin resistance, hemoglobin A1c [HbA1c ], glycated albumin [GA] and chronic liver disease [CLD]-HbA1c [average of HbA1c and GA/3]) were also measured. RESULTS Twelve months of moderate training significantly increased AT, which is an index of aerobic capacity, but no changes were observed in body weight, liver to spleen ratio, or intramuscular adipose tissue content. Glycated albumin significantly decreased (P < 0.05) and there tended to be a similar decrease in CLD-HbA1c (P < 0.1) after the exercise. The baseline serum triglyceride level correlated with changes in GA (P < 0.01) and CLD-HbA1c (P < 0.1). CONCLUSION The current results suggest that the combination of home-based step exercise at AT and BCAA supplementation enhances aerobic capacity and potentially improves glycemic control in patients with cirrhosis without changes in body weight. The baseline serum serum triglyceride may partially explain the degree of improvement in glycemic control with exercise and BCAA intervention.

Abstract
BACKGROUND Functional impairment is common in people with chronic liver disease (CLD), and improvement is expected following liver transplantation (LT). The Six-Minute Walk Test (6MWT) is an objective measure of functional performance. OBJECTIVE The aims of this study were: (1) to evaluate the feasibility of 6MWT performance after LT, (2) to compare post-LT 6MWT performance over time between patients with and without CLD, (3) to determine when post-LT 6MWT performance approaches expected values, and (4) to investigate predictors of poor 6MWT performance. METHODS The 6MWT was performed by 162 consecutive ambulatory participants (50 healthy controls, 62 with CLD, 50 with LT). Sex, age, and body mass index were used to predict expected 6MWT performance. Chi-square testing, analysis of variance, and Pearson coefficients compared percentage of predicted 6-minute walk distance (%6MWD) across groups. Multivariable mixed models assessed predictors of improvement. RESULTS The participants' mean age was 53.5 years (SD=13.0), 39.5% were female, and 39.1% were nonwhite. At 1-month post-LT, only 52% of all LT recipients met the inclusion criteria for 6MWT performance. Mean %6MWD values for female participants improved from 49.8 (SD=22.2) at 1 month post-LT to 90.6 (SD=12.8) at 1 year post-LT (P<.0001), which did not differ statistically from the CLD group (X̅=95.9, SD=15.6) or the control group (X̅=95.6, SD=18.0) (P=.58). However, at 1-year post-LT, mean %6MWD values for male participants (X̅=80.4, SD=19.5) remained worse than for both the CLD group (X̅=93.3, SD=13.7) and the control group (X̅=91.9, SD=14.3) (P=.03). Six-Minute Walk Test performance was directly correlated with the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) physical component score (r=.51, P<.01) and was inversely correlated with nonalcoholic steatohepatitis (r=-.52, P<.01) and diabetes (r=-.48, P<.05). In multivariate analysis adjusted for age and sex, hepatitis C independently predicted 6MWT improvement (estimated β=69.8, standard error=27.6, P=.01). LIMITATIONS A significant proportion of patients evaluated for enrollment were excluded due to level of illness early after LT (n=99, 47.4%). Thus, sampling bias occurred in this study toward patients without significant postoperative complications. CONCLUSIONS The 6MWT is a simple test of physical functioning but may be difficult to apply in LT recipients. The 6MWT performance improved following LT but was lower than expected, suggesting a low level of fitness up to 1 year following LT.

Abstract
OPINION STATEMENT Most widely recognized complications in cirrhotic patients include ascites, hepatic encephalopathy, variceal bleeding, kidney dysfunction, and hepatocellular carcinoma; however, malnutrition and muscle wasting (sarcopenia) constitute common complications which negatively impact survival, quality of life, and response to stressors, such as infection and surgery in patients with cirrhosis. Despite the important role that malnutrition and sarcopenia play in the prognosis of patients with cirrhosis, they are frequently overlooked, in part because nutritional assessment can be a difficult task in patients with cirrhosis due to fluid retention and/or overweight. Moreover, patients with cirrhosis may develop simultaneous loss of skeletal muscle and gain of adipose tissue, culminating in the condition of "sarcopenic obesity." In addition, muscle depletion is characterized by both a reduction in muscle size and increased proportion of intermuscular and intramuscular fat-denominated "myosteatosis." Sarcopenia in cirrhotic patients has been associated with increased mortality, sepsis complications, hyperammonemia, overt hepatic encephalopathy, and increased length of stay after liver transplantation. Muscularity assessment with cross-sectional imaging studies has become an attractive index of nutritional status evaluation in cirrhosis, as sarcopenia reflects a chronic detriment in general physical condition, rather than acute severity of the liver disease. In this review, we discuss the current diagnostic methods to evaluate malnutrition and muscle abnormalities in cirrhosis and also analyze the current knowledge regarding incidence and clinical impact of malnutrition and muscle abnormalities in cirrhosis and their impact after liver transplantation. We also discuss existing and potential novel therapeutic strategies for malnutrition in cirrhosis, emphasizing the recognition of sarcopenia in cirrhosis in an effort to improve survival and reduce morbidity related to cirrhosis. Finally, we analyze new studies including sarcopenia with the MELD score that seems to allow better prediction of mortality among cirrhotic patients waiting for liver transplantation.

Abstract
Introduction. Liver diseases influence musculoskeletal functions and may negatively affect the exercise capacity of patients with cirrhosis. Aim. To test the relationship between the six-minute walk test (6MWT), maximal inspiratory pressure (MIP), and exercise capacity (VO2peak) measures and the survival rate of patients with cirrhosis. Methods. This prospective cohort study consisted of 86 patients diagnosed with cirrhosis with the following aetiology: hepatitis C virus (HCV), hepatitis B virus (HBV), and/or alcoholic cirrhosis (AC). All patients were followed up for three years and submitted to the 6MWT, pressure measurements with a compound gauge, and an exercise test (VO2peak). Results. The survival analysis showed that the individuals who covered a distance shorter than 410 m during the 6MWT had a survival rate of 55% compared with a rate of 97% for the individuals who walked more than 410 m (p = 0.0001). Individuals with MIPs below -70 cmH2O had a survival rate of 62% compared with a rate of 93% for those with MIPs above -70 cmH2O (p = 0.0001). The patients with values below 17 mL/kg had a survival rate of 55% compared with a rate of 94% for those with values above 17 mL/kg (p = 0.0001). Conclusion. The 6MWT distance, MIP, and oxygen consumption are predictors of mortality in patients with cirrhosis.

Abstract
Loss of muscle mass and function is a common occurrence in both patients with decompensated cirrhosis and those undergoing liver transplantation. Sarcopenia is associated with morbidity and mortality before and after liver transplantation. The ability of skeletal muscle mass to recover after transplant is questionable, and long term adverse events associated with persistent sarcopenia have not been well studied. Limited data is available examining mechanisms by which decreased muscle mass might develop. It is not clear which interventions might reduce the prevalence of sarcopenia and associated health burdens. However, measures to either decrease portal hypertension or improve nutrition appear to have benefit. Research on sarcopenia in the liver transplant setting is hampered by differing methodology to quantify muscle mass and varied thresholds determining the presence of sarcopenia. One area highlighted in this review is the heterogeneity used when defining sarcopenia. The health consequences, clinical course and potential pathophysiologic mechanisms of sarcopenia in the setting of cirrhosis and liver transplantation are further discussed.

Abstract
INTRODUCTION Muscular weakness in combination with malnutrition can induce a global motor impairment and physical inactivity, adversely impairing the daily living activities and quality of life of end-stage liver disease patients who are candidates for liver transplantation. OBJECTIVES To evaluate functional status, pulmonary capacity, body composition and quality of life in end-stage liver disease patients who are candidates for liver transplantation; to verify if there is a correlation between the functional variables of the individuals tested through the 6-minute walk test (6MWT) and covariables: pulmonary function test (PFP), quality of life and body composition. METHODS This study was carried out at the Liver Transplantation Unit of the State University of Campinas (UNICAMP). We included 46 patients with end-stage liver disease who underwent the following evaluations: medical history, quality of life questionnaire "Short Form 36" (SF-36), surface electromyography (sEMG) of the diaphragm and rectus abdominis muscles, body composition assessment by electrical vioimpedance (BIA), 6MWT and PFP. RESULTS Univariate analysis and Pearson's correlation found correlations between distance walked on 6MWT and QOL (P = .006 and P = .02) and TBW (P = .5 and P = .02). Pearson's correlation were found between respiratory variables of 6MWT, QOL, and PFP. CONCLUSION The functional status may be correlated to body composition, quality of life and pulmonary capacity of patients with liver disease, candidates for transplantation.

Abstract
BACKGROUND In New Zealand, meat processing populations face many health problems as a result of the nature of work in meat processing industries. The primary aim of this study was to examine the feasibility of using a pedometer-based intervention to increase physical activity and improve health-related outcomes in a population of meat processing workers. METHODS A single-blinded randomized controlled trial (RCT) was conducted. A convenience sample of meat workers (n = 58; mean age 41.0 years; range: 18-65) participated in the trial. Participants were randomly allocated into two groups. Intervention participants (n = 29) utilized a pedometer to self monitor their activity, whilst undertaking a brief intervention, and educational material. Control participants (n = 29) received educational material only. The primary outcomes of ambulatory activity, and health-related quality of life, were evaluated at baseline, immediately following the 12-week intervention and three months post-intervention. RESULTS Fifty three participants completed the program (91.3% adherence). Adherence with the intervention group was high, 93% (n = 27/29), and this group increased their mean daily step count from 5993 to 9792 steps per day, while the control group steps changed from 5788 to 6551 steps per day from baseline. This increase in step counts remained significant within the intervention group p < 0.005; at three months post-intervention representing a 59% increase over baseline scores. There were significant group changes with large effect sizes for step count change (d = 1.94) and self-reported physical activity (p < 0.005; d = 2.59) at 12 weeks intervention. Further, results showed non-significant between-group differences in physical component (PCS) and mental component (MCS) scores (PCS: p = 0.44; MGD = 0.99, 95% CI, -1.6 to 3.6; ES = 0.14, and MCS p = 0.90, MGD = 0.15; 95% CI, -2.3 to 2.6, ES = 0.022) at 12 weeks intervention. CONCLUSIONS This research provides important information for a larger (RCT) in the future: results demonstrated that a pedometer-driven walking intervention in combination with goal setting, and self-monitoring supported by weekly e-mails are feasible and potentially effective in increasing step count within the workplace setting over the short term.

Variations in DEPDC5 gene and its association with chronic hepatitis C virus infection in Saudi Arabia. BMC Infect Dis 2014; 14:632. [PMID: 25551790 PMCID: PMC4311515 DOI: 10.1186/s12879-014-0632-y] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2014] [Accepted: 11/13/2014] [Indexed: 02/08/2023] Open
Abstract
Background Variations at DEPDC5 gene have been recently reported as genetic markers associated with hepatocellular carcinoma (HCC) progression in chronic HCV-infected patients. This study was conducted to assess the association of DEPDC5 variants with advanced liver cirrhosis and HCC development among chronic HCV-infected patients in Saudi Arabian population. Methods Six-hundred and one HCV-infected patients were genotyped for DEPDC5 polymorphisms (rs1012068 and rs5998152), in comparison with 592 non-infected healthy control subjects. The allelic frequency and genotype distribution of both DEPDC5 polymorphisms were determined followed by haplotype frequency estimation and multiple logistic regression analysis. Results The frequency of the risk alleles of both rs1012068 and rs5998152 was shown to be more in healthy control subjects than in patients (p = 0.0001, OR = 0.704, CI = 0.591-0.839; p = 0.002, OR = 0.761, CI = 0. 0.639-0.907, respectively). Also, our results revealed that GT for SNP rs1012068 (OR =1.715; 95% CI 1.132-2.597; p = 0.0104) and CT for SNP rs5998152 (OR = 1.932; 95% CI 1.276-2.925; p = 0.0017) showed significant association with development of cirrhosis compared with the GG and CC genotypes, respectively. The data also revealed that subjects with the T allele of both SNPs appeared to have a lower susceptibility to HCV-related cirrhosis/HCC than those with the G allele of rs1012068 (p = 0.038, OR = 1.353, 95 % CI 1.017-1.800) and C allele of rs5998152 (p = 0.043, OR = 1.342, 95 % CI 1.010-1.784). Haplotype analysis showed that a combination of T-T alleles of rs1012068 and rs5998152 was significantly associated with liver cirrhosis (frequency = 71.3% and p = 0.027) and with cirrhosis/HCC (frequency = 71.4% and P = 0.045). Also, multiple logistic regression analysis showed that rs5998152 (OR = 2.844, 95% CI 1.333-6.069 and p = 0.007), rs1012068 (OR = 2.793, 95% CI 1.316-5.928 and p = 0.010), age (OR = 1.029, 95% CI 1.001-1.057 and p = 0.041) and HCV genotypes (OR = 0.247, 95% CI 0.097-0.630 and p = 0.003) were independently associated with chronicity of HCV infection. Conclusion Genetic variations in DEPDC5 gene region may influence HCV-associated liver cirrhosis and/or HCC development.

Abstract
BACKGROUND Physical exercise could improve functional limitations, muscle mass, and health-related quality of life (HRQoL) in patients with cirrhosis. AIM The purpose of this study was to evaluate the efficacy and safety of an exercise programme and leucine supplementation to increase exercise capacity, muscle mass, and HRQoL in patients with cirrhosis. PATIENTS AND METHODS Seventeen outpatients with cirrhosis were randomized to an exercise group (n = 8) or a control group (n = 9) in a pilot study. The programme of moderate exercise was performed for 12 weeks under supervision of a physiotherapist. All patients received oral leucine (10 g/day) during the study. At baseline and at the end of the study, we determined exercise capacity (6-min walk and 2-min step tests), anthropometric measurements, and HRQoL by Short Form-36 (SF-36) questionnaire. We also analyzed safety regarding complications of cirrhosis, liver and renal function, inflammatory response and oxidative stress. RESULTS In the exercise group, exercise capacity improved, as shown by the increase in the 6-min walk test from 365 (160-420) to 445 m (250-500) (p = 0.01), and in the 2-min step test (p = 0.02). Lower thigh circumference also increased, from 41 (34-53) to 46 cm (36-56) (p = 0.02), and the domains of SF-36 general health (p = 0.03), vitality (p = 0.01) and social function (p = 0.04) improved significantly. In the control group, no statistically significant changes were observed in any of the parameters. We did not observe complications of cirrhosis in either group during the study. CONCLUSIONS A programme of moderate physical exercise together with leucine supplements in patients with cirrhosis is safe and improves exercise capacity, leg muscle mass and HRQoL.
