Abstract
With age, the prevalence of diseases such as fatty liver disease, cirrhosis, and type two diabetes increases. Approaches to both predict abdominal age and identify risk factors for accelerated abdominal age may ultimately lead to advances that will delay the onset of these diseases. We build an abdominal age predictor by training convolutional neural networks to predict abdominal age (or "AbdAge") from 45,552 liver magnetic resonance images [MRIs] and 36,784 pancreas MRIs (R-Squared = 73.3 ± 0.6; mean absolute error = 2.94 ± 0.03 years). Attention maps show that the prediction is driven by both liver and pancreas anatomical features, and surrounding organs and tissue. Abdominal aging is a complex trait, partially heritable (h_g2 = 26.3 ± 1.9%), and associated with 16 genetic loci (e.g. in PLEKHA1 and EFEMP1), biomarkers (e.g body impedance), clinical phenotypes (e.g, chest pain), diseases (e.g. hypertension), environmental (e.g smoking), and socioeconomic (e.g education, income) factors.

[PMID: 35243114 PMCID: PMC8826036 DOI: 10.21037/tgh-20-325] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Accepted: 04/08/2021] [Indexed: 08/10/2023] Open
Abstract
OBJECTIVE The purpose of this manuscript is to identify the pathophysiology of the metabolic abnormalities observed in cirrhosis and to uncover associations, if any, to its complications, such as sarcopenia and hepatic encephalopathy (HE). BACKGROUND Liver dysfunction in cirrhosis is known to be a precipitating factor in the disruption of many physiological pathways, specifically nutrient metabolism. As a result, affected patients are highly susceptible to derangements of processes affecting multiple classes of macro- and micronutrients, including proteins, carbohydrates, electrolytes, vitamins, and minerals. These disruptions are thought to be contributory to the pathogenesis of known complications of cirrhosis. METHODS Literature research of relevant topics was conducted for the above stated objective; sources were limited to articles from peer-reviewed journals published within the last 30 years. CONCLUSION This research established that there is positive correlation between nutrient derangements and the increased risk of complications of cirrhosis, which themselves carry significant morbidity and mortality risk. It also established that some nutrient and electrolyte abnormalities are independent indicators of prognosis and adverse outcomes, such as mortality. This also highlights the importance of comprehension of anomalous metabolism and its complications as it necessitates serious consideration in clinical care. In addition to medical management, cirrhotic patients also require ancillary assessment, such as comprehensive nutritional evaluation, to identify and treat reversible nutritional derangements. This consideration provides the best opportunity to achieve maximal health outcomes in the cirrhotic patient population.

Abstract
Risk of hepatocellular carcinoma (HCC) in young adults might be clinically overlooked for future HCC risk. Thus, we examined the association between weight change and future risk of developing HCC in young adults. We collected a nationwide and population-based cohort data of more than 2.2 million men and women aged between 20 and 39 who were without previous cancer diagnosis and underwent two consecutive biennial national health screening between 2002 and 2005 from the National Health Insurance Service database. The individuals were categorized as weight loss (≥5.0 kg and 2.0-4.9 kg), stable weight (weight gain or loss <2.0 kg), and weight gain (2.0-4.9 kg and ≥5.0 kg) and were followed-up for incident HCC from 1 January 2006 to 31 December 2018. During 12 years of follow-up, there were 2694 HCCs in men and 306 HCCs in women. In the multivariable Cox proportional hazards model adjusted for socioeconomic, health behavior, medical characteristics, and family history, weight gain of more than 5.0 kg and between 2.0 and 4.9 kg were associated with significantly increased risk in young men [hazard ratio (HR) 1.16, 95% confidence intervals (95% CI) 1.01-1.32] and young women (HR 1.34, 95% CI 1.01-1.77), respectively. Protective association of weight loss with HCC was not observed. The association of weight gain and HCC risk was stronger in young adults with underlying liver diseases compared to those without any liver disease (Pheterogeneity < 0.001). Weight gain during young adulthood should not be clinically overlooked for future HCC risk, especially among those with underlying liver diseases.

Abstract
Exposure to the herbicides Paraquat and Roundup® may cause cell lesions due to an increase in oxidative stress levels in different biological systems, even in the liver. The aim of this study was to analyze the effect of melatonin on liver of rats exposed to herbicides. A total of 35 rats were randomly divided into seven equal-sized groups: control, Paraquat, Roundup®, Paraquat + Roundup®, Paraquat + melatonin, Roundup® + melatonin, and Paraquat + Roundup® + melatonin. Samples of blood and hepatic tissue were collected at the end of the seventh day of exposure and treatment with melatonin. Body weight, hematological parameters, and histopathological, biochemical analyses and determination of oxidative stress levels in liver were evaluated. Body weight was compromised (P < 0.01). Alterations of hematologic parameters were significant when compared to control (P < 0.001). Biochemically, serum levels of albumin decreased (P < 0.001), but serum levels of alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase increased (P < 0.001). Histopathology revealed necrotic hepatocytes, portal and central-lobular inflammatory infiltrate, congestion of capillaries. Serum levels of thiobarbituric acid reactive substances were found to be significantly elevated (P < 0.05; P < 0.001), and serum level of reduced glutathione was significantly lower (P < 0.05; P < 0.001). The groups treated concomitantly with melatonin revealed results similar to those of the control. However, melatonin acted as a protective agent for the liver against experimentally induced hepatic toxicity, promoting prevention of body weight, oxidative stress, and normalization of hematological and biochemical parameters.

Abstract
AIMS Liver cirrhosis is the main chronic liver disease and is considered a catabolic disease. Cirrhotic patients have a low energy intake and high energy expenditure at rest, leading to metabolic disorders. Malnutrition is associated with complications of cirrhosis and has been shown that a nutritional intervention with increase of energy intake improves the survival of cirrhotic patients. Therefore, our aim was to evaluate the effect of a high sucrose diet in the liver of animals with cirrhosis induced by thioacetamide and investigate the mechanism involved. MAIN METHODS Male Wistar rats were divided into three groups: Control; Thioacetamide; and Thioacetamide + high sucrose diet. The thioacetamide was administrated (100 mg kg-1) intraperitoneally and the sucrose was offered in drinking water (300 g L-1). KEY FINDINGS The administration of thioacetamide was associated with fibrosis and inflammatory infiltrate in the liver and increased levels of transaminases enzymes. The high sucrose diet promoted a reduction of theses parameters in cirrhotic rats. The malnutrition observed in cirrhotic rats was attenuated by the high sucrose diet shown by the improvements in weight loss, subcutaneous fat, and caloric intake. The high sucrose diet also attenuated the oxidative stress present in the liver of animals with thioacetamide-induced cirrhosis. SIGNIFICANCE The high sucrose diet had anti-inflammatory and anti-oxidant effects in the liver of animals with thioacetamide-induced cirrhosis. In addition, the high sucrose diet also improved malnutrition and catabolism present in cirrhosis. Thus, a high sucrose diet may be a therapeutic option for cirrhotic patients in a catabolic state.

Comparing the effects of whey and casein supplementation on nutritional status and immune parameters in patients with chronic liver disease: a randomised double-blind controlled trial. Br J Nutr 2020; 125:768-779.

Abstract
Protein supplementation may be beneficial for patients with chronic liver disease (CLD). This study compared the effects of whey protein isolate (WP) and casein (CA) supplementation on nutritional status and immune parameters of CLD patients who were randomly assigned to take 20 g of WP or CA twice per d as a supplement for 15 d. Body composition, muscle functionality and plasmatic immunomarkers were assessed before and after supplementation. Patients were also classified according to the model for end-stage liver disease (MELD) into less (MELD < 15) and more (MELD ≥ 15) severe disease groups. Malnutrition, determined by the Subjective Global Assessment at baseline, was observed in 57·4 % and 54·2 % of patients in the WP and CA groups, respectively (P = 0·649). Protein intake was lower at baseline in the WP group than in the CA group (P = 0·035), with no difference after supplementation (P = 0·410). Both the WP and CA MELD < 15 groups increased protein intake after supplementation according to the intragroup analysis. No differences were observed in body composition, muscle functionality, most plasma cytokines (TNF, IL-6, IL-1β and interferon-γ), immunomodulatory proteins (sTNFR1, sTNFR2, brain-derived neurotrophic factor and glial cell line-derived neurotrophic factor) or immunomodulatory hormones (adiponectin, insulin and leptin) after supplementation in the WP groups at the two assessed moments. WP supplementation increased the levels of interferon-γ-induced protein-10/CXCL10 (P = 0·022), eotaxin-1/CCL11 (P = 0·031) and monocyte chemoattractant protein-1/CCL2 (P = 0·018) and decreased IL-5 (P = 0·027), including among those in the MELD ≥ 15 group, for whom IL-10 was also increased (P = 0·008). Thus, WP consumption by patients with CLD impacted the immunomodulatory responses when compared with CA with no impact on nutritional status.

Abstract
BACKGROUND AND AIMS Sarcopenia or skeletal muscle loss adversely affects outcomes in cirrhosis. The impact of aetiology of liver disease on the severity or the rate of muscle loss is not known. METHODS Consecutive, well-characterized adult patients with cirrhosis due to viral hepatitis (VH), alcoholic liver disease (ALD) or non-alcoholic fatty liver disease (NAFLD) and non-diseased controls with at least two temporally distinct abdominal CT (computed tomography) scans were evaluated. Psoas, paraspinal and abdominal wall muscle areas at the L3 vertebra level were quantified on the CT scans. Standardized rate of change in muscle area was expressed as change in area/100 days. Univariate and multivariable analyses were performed to identify contributors to rate of muscle loss and survival. RESULTS Among 83 cirrhotics (NAFLD n = 26, ALD n = 39, VH n = 18), there were 20 (24.1%) deaths over 62.7 ± 41.3 months. The mean percentage change in psoas area was -0.03 ± 0.05/100d in controls and -3.52 ± 0.45/100d in cirrhosis (P < .001). The mean percentage change in psoas area was -1.72 ± 0.27/100d in NAFLD, -5.28 ± 0.86/100d in ALD and -2.29 ± 0.28/100d in VH. Among cirrhotics, patients with ALD had the lowest initial muscle area and most rapid rate of reduction in muscle area. Aetiology of liver disease, model for end-stage liver disease (MELD) and the rate of loss of muscle area were independent risk factors for survival. CONCLUSIONS Aetiology of liver disease is an independent risk factor for sarcopenia with the greatest rate of muscle loss noted in ALD. Survival in cirrhosis was dependent on initial muscle mass, rate of muscle loss and MELD score.

Abstract
Direct Acting Agents (DAAs) have high cure rate but still lack the knowledge of their effect on hepatic steatosis in chronic hepatitis C (CHC). Controlled Attenuation Parameter (CAP), evaluated with transient elastography, could help in assessment of steatosis grades. We aim to evaluate the effect of DAAs on BMI and steatosis in CHC using CAP. This cohort study included 155 CHC Egyptian patients divided into three groups according to the DAAs regimens. All patients were subjected to pre-treatment and 3-months post-treatment evaluation including BMI, laboratory workup and liver stiffness measurement with simultaneous CAP determination using the (FibroScan®) M probe. Patients mean age was 45.78 ± 11.6 years, 60.6% were females, mean BMI 26.63 ± 2.75 and 18.1% were cirrhotic. Baseline assessment revealed no steatosis in 43.9%, 32.9% had mild-moderate steatosis and 23.2% had severe steatosis. The overall sustained virological response 12 was 93.6%. Follow-up revealed stationary steatosis in 56.7% of patients and regression in 21.3%. Mean pre-treatment CAP were significantly lower in responders 244.9 ± 62.4 dB/m versus non-responders; 300 ±28.4 dB/m (P = 0.04). ROC curve delineated 273 dB/m as best cutoff for detection of responders with an AUC of 0.801, sensitivity 68.2%, and specificity 100%. BMI significantly increased after treatment (P = 0.004) particularly in patients with worsened steatosis (P = 0.001). Steatosis significantly correlated with BMI (r = 0.3, P value = < 0.001). DAAs causes a significant change in steatosis grade in a subset of treated patients. Pretreatment CAP was significantly lower in responders. BMI significantly increases following treatment particularly in patients with worsened steatosis.
