Temporal trend in non-melanoma skin cancer mortality in China, 1992-2021: an analysis for the global burden of disease study 2021

Introduction

Non - melanoma skin cancer (NMSC) is a widespread malignant neoplasm affecting the skin globally. In China, over the past 30 years, the prevalence and incidence of NMSC have changed significantly, yet mortality rate (MR) data is scarce. The aim is to assess the MR data of NMSC patients worldwide from 1992 to 2021, analyze its temporal trends, and provide valuable epidemiological information for future prevention and management strategies of NMSC.

Methods

Using data from the Global Burden of Disease Study 2021 (GBD 2021), we analyzed crude mortality rate (CMR), age-standardized mortality rate (ASMR), and sex- and age-specific mortality trends, with temporal patterns assessed through longitudinal comparisons.

Results

The MR for NMSC has shown an upward trend globally. From 1992 to 2021, both the CMR and ASMR for NMSC have increased substantially. The global ASMR has risen by approximately 30% during this period. Males have a higher ASMR compared to females, and the elderly population exhibits an accelerated and elevated ASMR trend for NMSC. In China, the mortality of NMSC is on the rise, with the current male MR exceeding that of females. Although the ASMR is projected to decline by 2030, the number of mortality cases is expected to increase, especially among males. The MR for NMSC shows a significant bias towards the elderly demographic.

Discussion

The increasing mortality of NMSC, both globally and in China, highlights the importance of effective prevention and management strategies. In addition to implementing prevention and intervention measures in susceptible populations, it is crucial to establish a screening framework for NMSC to detect minor symptoms in a timely manner. This will help in early diagnosis and potentially reduce the mortality rate associated with NMSC. Thank you for your editorial support.

The functions of gut microbiota-mediated bile acid metabolism in intestinal immunity

BACKGROUND

Bile acids, derived from cholesterol in the liver, consist a steroidal core. Primary bile acids and secondary bile acids metabolized by the gut microbiota make up the bile acid pool, which modulate nuclear hormone receptors to regulate immunity. Disruptions in the crosstalk between bile acids and the gut flora are intimately associated with the development and course of gastrointestinal inflammation.

AIM OF REVIEW

This review provides an extensive summary of bile acid production, transport and metabolism. It also delves into the impact of bile acid metabolism on the body and explores the involvement of bile acid-microbiota interactions in various disease states. Furthermore, the potential of targeting bile acid signaling as a means to prevent and treat inflammatory bowel disease is proposed.

KEY SCIENTIFIC CONCEPTS OF REVIEW

In this review, we primarily address the functions of bile acid-microbiota crosstalk in diseases. Firstly, we summarize bile acid signalling and the factors influencing bile acid metabolism, with highlighting the immune function of microbially conjugated bile acids and the unique roles of different receptors. Subsequently, we emphasize the vital role of bile acids in maintaining a healthy gut microbiota and regulating the intestinal barrier function, energy metabolism and immunity. Finally, we explore differences of bile acid metabolism in different disease states, offering new perspectives on restoring the host's health and the gastrointestinal ecosystem by targeting the gut microbiota-bile acid-bile acid receptor axis.

Efruxifermin in Compensated Liver Cirrhosis Caused by MASH

BACKGROUND

In phase 2 trials involving patients with stage 2 or 3 fibrosis caused by metabolic dysfunction-associated steatohepatitis (MASH), efruxifermin, a bivalent fibroblast growth factor 21 (FGF21) analogue, reduced fibrosis and resolved MASH. Data are needed on the efficacy and safety of efruxifermin in patients with compensated cirrhosis (stage 4 fibrosis) caused by MASH.

METHODS

In this phase 2b, randomized, placebo-controlled, double-blind trial, we assigned patients with MASH who had biopsy-confirmed compensated cirrhosis (stage 4 fibrosis) to receive subcutaneous efruxifermin (at a dose of 28 mg or 50 mg once daily) or placebo. The primary outcome was a reduction of at least one stage of fibrosis without worsening of MASH at week 36. Secondary outcomes included the same criterion at week 96.

RESULTS

A total of 181 patients underwent randomization and received at least one dose of efruxifermin or placebo. Of these patients, liver biopsy was performed in 154 patients at 36 weeks and in 134 patients at 96 weeks. At 36 weeks, a reduction in fibrosis without worsening of MASH occurred in 8 of 61 patients (13%) in the placebo group, in 10 of 57 patients (18%) in the 28-mg efruxifermin group (difference from placebo after adjustment for stratification factors, 3 percentage points; 95% confidence interval [CI], -11 to 17; P = 0.62), and in 12 of 63 patients (19%) in the 50-mg efruxifermin group (difference from placebo, 4 percentage points; 95% CI, -10 to 18; P = 0.52). At week 96, a reduction in fibrosis without worsening of MASH occurred in 7 of 61 patients (11%) in the placebo group, in 12 of 57 patients (21%) in the 28-mg efruxifermin group (difference from placebo, 10 percentage points; 95% CI, -4 to 24), and in 18 of 63 patients (29%) in the 50-mg efruxifermin group (difference from placebo, 16 percentage points; 95% CI, 2 to 30). Gastrointestinal adverse events were more common with efruxifermin; most events were mild or moderate.

CONCLUSIONS

In patients with compensated cirrhosis caused by MASH, efruxifermin did not significantly reduce fibrosis at 36 weeks. (Funded by Akero Therapeutics; SYMMETRY ClinicalTrials.gov number, NCT05039450.).

Efficacy and Safety of Novel Oral Anti-Cholestatic Agents for Primary Biliary Cholangitis: Meta-Analyses and Systematic Review

Background: Primary biliary cholangitis (PBC) is a chronic autoimmune liver disease characterized by progressive bile duct damage and cholestasis. While ursodeoxycholic acid (UDCA) is the first-line therapy, approximately 40% of patients have incomplete responses, necessitating alternative treatments. This systematic review and meta-analysis evaluate the efficacy and safety of novel oral anti-cholestatic agents for PBC. Methods: A systematic literature search was conducted in electronic databases up to September 2024. Randomized controlled trials, cohort studies, and case-control studies evaluating novel oral anti-cholestatic agents in adult PBC patients were included. The primary outcome was a change in alkaline phosphatase (ALP) levels. Safety was assessed by the incidence of serious adverse events. Random-effect meta-analyses were performed. Results: Ten studies involving 878 patients were analyzed. Novel agents included seladelpar, fenofibrate, saroglitazar, bezafibrate, elafibranor, and budesonide. The meta-analysis showed significant reductions in ALP levels with novel agents compared to the controls (SMD -2.80; 95% CI -3.56, -2.03; p < 0.00001), with high heterogeneity (I2 = 93%). Saroglitazar achieved the largest effect size. There was no significant difference in serious adverse events between novel agents and controls (OR 1.21; 95% CI 0.81, 1.83; p = 0.35). Conclusions: Novel oral anti-cholestatic agents show promise in improving biochemical markers in PBC patients with suboptimal UDCA responses, with a safety profile comparable to controls. However, study heterogeneity and limited long-term data restrict direct comparisons. Larger standardized trials with extended follow-up are needed to confirm long-term efficacy and safety.

Effectiveness of Mobile Health Interventions for Reducing Sitting Time in Older Adults: Systematic Review and Meta-Analysis

BACKGROUND

Mobile health (mHealth) provides health information through electronic devices, even at home. The escalating prevalence of sedentary behaviors among older adults, which leads to increased adverse health outcomes, underscores the pressing need for a comprehensive understanding of the effectiveness of mHealth interventions.

OBJECTIVE

This study aims to examine the effectiveness of mHealth interventions in the sitting time of older adults (age 55 years).

METHODS

A systematic review and meta-analysis of randomized controlled trials was conducted to evaluate the effects of mHealth interventions on total sitting time during waking hours, excluding sleep. A literature search was conducted using multiple databases, including PubMed, Embase, Web of Science, and Cochrane, covering articles published from the inception of each database through October 2023. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were explicitly applied to structure this report. Methodological quality was assessed using the Cochrane Risk of Bias (ROB 2) tool for randomized controlled trials and the Methodological Index for Non-Randomized Studies (MINORS) tool for nonrandomized studies. Two independent reviewers screened the studies, extracted data, and assessed methodological quality using established criteria. Meta-analyses were performed using Review Manager (version 5.4; Cochrane Collaboration).

RESULTS

Ten studies were identified, of which 3 were included in the meta-analysis, while the remaining 7 were assessed exclusively in the systematic review. The interventions predominantly took place in community settings (n=3) and home-based settings (n=3). Three studies aimed to decrease sedentary behavior and 7 aimed to increase physical activity. The interventions were primarily conducted once daily (n=7) via mobile devices such as smartphones (n=7) and typically involved a single intervention delivered at different time intervals, such as every 15, 20, or 30 minutes (n=4). The interventions typically lasted 12 weeks (n=4) and used objective assessment tools, such as the ActiGraph GT3X+ (n=8). The included studies applied the habit formation theory (n=1), the self-efficacy theory (n=1), the social cognitive theory (n=1), and the social-ecological theory (n=1) as frameworks. Additionally, behavior change techniques, including "goal setting," "problem-solving," "action planning," and "review behavior goal(s)" (n=6), were used. Meta-analysis of the 3 studies included showed a significant decrease in sedentary behavior with mHealth interventions compared with conventional or no interventions (weighted mean difference [WMD]=59.1 min/d, 95% CI 99.1 to 20.2; P=.003).

CONCLUSIONS

mHealth interventions effectively reduce sitting time in older adults. Strategies using interventions with specific frequencies and durations, dedicated mobile monitoring devices, and behavior change techniques showed the potential to reduce sedentary behavior among older adults. These results also underscore the potential of mHealth as a key tool for promoting the well-being of older adults through technology-driven public health efforts.

Exploring the association between chemotherapy and prognosis among patients less than 50 years old with hepatocellular carcinoma: a retrospective cohort study based on the SEER database

BACKGROUND/AIM

Hepatic carcinoma, including hepatocellular carcinoma (HCC), is one of the most common malignant tumors globally, with an increasing incidence among younger populations. While chemotherapy is effective for advanced HCC, its impact on the prognosis of younger patients, who typically have better physiological conditions, remains unclear. Younger patients may have different tumor biology and chemotherapy responses than older patients. This study aims to evaluate the impact of chemotherapy on the prognosis and survival rates of younger HCC patients.

METHODS

A retrospective analysis was conducted using the Surveillance, Epidemiology, and End Results Program (SEER) database, which provides information on cancer statistics among the US population. We selected patients diagnosed with primary HCC between 2010 and 2015. The patients were divided into two groups based on whether they received chemotherapy or not. Kaplan-Meier analyses were utilised to evaluate the impact of chemotherapy on prognosis by comparing the overall survival (OS) and cancer-specific survival (CSS) between the two groups. After performing 1:1 propensity score matching (PSM), the differences in OS and CSS were reassessed.

RESULTS

Before PSM, there were 1662 participants with primary HCC. After PSM, the sample was reduced to 1154 participants, with 577 individuals in each chemotherapy and non-chemotherapy group. Before PSM, there was no statistically significant difference in OS and CSS between the chemotherapy and non-chemotherapy groups (P = 0.25 and P = 0.06). After PSM, although the survival time in the chemotherapy group was slightly extended, the difference remained statistically insignificant (P = 0.09 and P = 0.38). Kaplan-Meier curves indicated no significant difference between the chemotherapy and non-chemotherapy groups, both before and after PSM, further supporting the conclusion that chemotherapy did not significantly improve survival in young patients with HCC.

CONCLUSION

Chemotherapy did not significantly improve survival for young patients with HCC. Treatment decisions should be approached cautiously, especially in cases with complex tumor characteristics. Future studies should explore the mechanisms of chemotherapy in younger patients and develop personalized treatment strategies to improve long-term outcomes.

Hepatic encephalopathy in cirrhosis: therapies and developments

Hepatic encephalopathy (HE) is a frequent decompensation in patients with cirrhosis, which significantly affects morbidity and mortality. Ammonia is a major neurotoxin implicated in the pathogenesis, progression, and severity of HE, and various organs including the gut, muscle, kidney, and brain are involved in its metabolism. Therefore, therapeutic management involves reducing ammonia production and increasing its elimination from the blood and the brain. Prevention of HE in patients at high risk of first and recurrent episodes is important for prolonging survival. Various anti-ammonia therapies with synergistic and complementary actions have been attempted for overt HE and for prophylaxis of the first and recurrent episodes of HE. In the current review, we summarize the currently used and under-development pharmacotherapies/procedure(s) for HE in cirrhosis and their mechanism of action. Primary and secondary prophylaxis with monotherapies and combination therapies are also discussed.

Twenty-five years of WWOX insight in cancer: a treasure trove of knowledge

More than two decades ago, MD Anderson Cancer group discovered, characterised, and identified the WW domain-containing oxidoreductase (WWOX) as a genes of interest mapping to the chromosomal region 16q23.3-24.2. This was pioneering research since WWOX is a critical tumour suppressor gene implicated in various cancers, involving interactions with numerous signalling pathways and molecular mechanisms. Notably, it inhibits the Wnt/β-catenin pathway, which is often activated in tumours. This inhibition helps prevent tumour formation by regulating cell proliferation and promoting apoptosis. Restoration of WWOX expression in cancer cell lines has been shown to reduce tumour growth and increased sensitivity to treatments. In addition to its role in tumour suppression, WWOX has been found to interact with proteins involved in critical signalling pathways such as TGF-β. Recent advancements allowed to reveal its interactions with key proteins and microRNAs that regulate cellular adhesion, invasion, and motility. Proteomic studies have shown that WWOX directly interacts with signalling molecules like Dishevelled and SMAD3, further underscoring its role in antagonizing metastasis. Challenges remain in translating this knowledge into clinical applications. For instance, the mechanisms underlying WWOX loss in tumours and its role across diverse cancer types require further investigation. Overall, WWOX serves as a vital player in maintaining cellular stability and preventing cancer progression through its multifaceted functions. Here, we include an updated molecular function of WWOX in cancers to possibly contribute to the potential use of WWOX expression as a biomarker regarding prognosis and response to the treatment. CLINICAL TRIAL NUMBER: Not applicable.

Characteristics of serum bile acid profiles among individuals with metabolic dysfunction-associated steatotic liver disease

BACKGROUND

Metabolic dysfunction-associated steatotic liver disease (MASLD) has become the predominant chronic liver condition globally. Bile acid (BA) metabolism contributes significantly to MASLD progression. In this multicenter clinical study, we aimed to characterize serum BA profiles in patients with MASLD and identify specific alterations compared to healthy controls.

METHODS

All MASLD cases were sourced from the gastroenterology outpatient departments of Shanghai Baoshan Hospital of Integrated Chinese and Western Medicine, Shanghai Baoshan District Songnan Community Health Service Center, and Lianyungang Oriental Hospital between June 2015 and December 2019. The data were analyzed using SPSS version 26.0, with a p-value of less than 0.05 considered significant.

RESULTS

A total of 215 participants (35.3% women) with MASLD and 49 controls (44.9% women), aged 18-65 years, were included. MASLD patients showed higher levels of serum total BA (TBA), cholic acid (CA), chenodeoxycholic acid (CDCA), and ursodeoxycholic acid (UDCA) (p < 0.05, p < 0.01) when compared to controls. Furthermore, women patients with MASLD demonstrated notably higher levels of lithocholic acid (LCA), glycolithocholic acid (GLCA), and taurolithocholic acid (TLCA) than men patients with MASLD (p < 0.025, p < 0.01). Compared to women, men exhibited a higher proportion of primary to secondary BAs. Additionally, in men patients with MASLD, the serum concentrations of CA, CDCA, glycocholic acid (GCA), glycochenodeoxycholic acid (GCDCA), and taurochenodeoxycholic acid (TCDCA) exhibited significant negative correlations with ALT levels, while deoxycholic acid (DCA) and TLCA showed negative correlations with BMI.

CONCLUSIONS

Patients with MASLD exhibited notable variations in BA profiles, including sex-specific differences. This study provides corresponding evidence on the association between BAs and MASLD.

Plasmid-Based Reverse Genetics System Enabling One-Step Generation of Genotype 3 Hepatitis E Virus

Hepatitis E virus (HEV) is a positive-sense, single-stranded RNA virus that poses a significant public health risk, yet its study is hindered by the complexity of conventional RNA-based reverse genetics systems. These systems require multiple steps, including genome cloning, in vitro transcription, and capping, making them labor-intensive and susceptible to RNA degradation. In this study, we developed a single-step, plasmid-based HEV expression system that enabled direct intracellular transcription of the full-length HEV genome under a cytomegalovirus immediate-early (CMV-IE) promoter. The viral genome was flanked by hammerhead (HH) and hepatitis delta virus (HDV) ribozymes to ensure precise self-cleavage and the generation of authentic 5' and 3' termini. This system successfully supported HEV genome replication, viral protein expression, and progeny virion production at levels comparable to those obtained using in vitro-transcribed, capped HEV RNA. Additionally, a genetic marker introduced into the plasmid construct was stably retained in progeny virions, demonstrating the feasibility of targeted genetic modifications. However, plasmid-derived HEV exhibited delayed replication kinetics, likely due to the absence of an immediate 5' cap. Attempts to enhance capping efficiency through co-expression of the vaccinia virus capping enzyme failed to improve HEV replication, suggesting that alternative strategies, such as optimizing the promoter design for capping, may be required. This plasmid-based HEV reverse genetics system simplifies the study of HEV replication and pathogenesis and provides a versatile platform for the genetic engineering of the HEV genome.

Characteristics and Outcomes of Hepatocellular Carcinoma in Patients with Autoimmune Hepatitis

BACKGROUND

The incidence of HCC in patients with autoimmune hepatitis (AIH) is low and, due to the paucity of data in the literature, a thorough characterization of these patients is missing.

AIM

To describe the main characteristics and outcome of patients with AIH and HCC.

METHODS

Among patients with HCC included in the Italian Liver Cancer (ITA.LI.CA) database during the period 2009-2022, we selected those with AIH, and we described their liver disease characteristics, modality of HCC diagnosis, tumor stage, treatment, and outcome.

RESULTS

Among 10,026 patients with HCC, we identified 23 patients (0.2%) with AIH (43.5% males, 69.6% aged > 65 years, 91.0% with cirrhosis). Fifteen patients (65.2%) had co-factors of liver disease [8 patients (34.8%) metabolic dysfunction-associated steatotic liver disease, 4 patients (17.4%) alcohol abuse, 3 patients (13.0%) AIH/Primary Biliary Cholangitis overlap syndrome]. Tumors diagnosed under surveillance (60.9%) were more frequently uninodular (85.7% vs 66.6%, p = 0.146) and Milan-in (85.7% vs 44.4%, p = 0.066) than those diagnosed outside surveillance. Treatment with curative intent was more frequent among patients under surveillance (78.6% vs 33.3%, p = 0.077). Median overall survival was 41.7 months and was remarkably longer in patients under surveillance than in those diagnosed outside surveillance (68.2 vs 27.4 months, p = 0.032).

CONCLUSION

AIH accounts for a minimal fraction of patients with HCC, and in most patients, risk co-factors for HCC are present. In patients with AIH, too, surveillance is associated with better tumor stage, higher access rate to potentially curative treatments, and improved survival.

Liver cirrhosis in metabolic dysfunction-associated steatohepatitis

In the present narrative review, we have summarized the current evidence on the natural progression of metabolic dysfunction-associated steatohepatitis (MASH) cirrhosis observed through the placebo arm in clinical trials and observational studies. The outcomes scrutinized throughout our review were histology-related changes, non-invasive fibrosis markers, indicators of decompensation, end-stage hepatic complications, and mortality reported during the different clinical trials. Given the short duration of clinical trials, observational studies were included to obtain better insight into the long-term progression and prognosis of MASH cirrhosis. Lastly, new updates about MASH cirrhosis treatments were listed, and the results of these randomized clinical trials were described to enhance our understanding of our current standing in the treatment of MASH cirrhosis.

Risk factors and prediction for DILI in clinical practice

INTRODUCTION

Drug-induced liver injury is an important adverse effect and can be caused by various medications, including novel therapeutic agents. The risk stratification of patients susceptible to DILI is a growing field.

AREAS COVERED

The current article highlights new studies on risk stratification regarding risk factors of DILI, prediction of liver injury, and predictors of severe outcomes. Studies on patient demographic and genetic risk factors are discussed, in addition to the potential role of concomitant medications that may affect the risk of DILI.

EXPERT OPINION

Although much is known about patient risk factors for DILI, a better combination of these factors into risk scores is needed to predict which patients are particularly susceptible. Knowledge of these risk factors might determine drug treatment in the near future, as well as the need for routine monitoring of liver tests.

Peptidoglycan isolated from the fruit of Lycium barbarum alleviates liver fibrosis in mice by regulating the TGF-β/Smad7 signaling and gut microbiota

The hepatoprotective effect of the fruit of Lycium barbarum has been documented in China over millennia. Lycium barbarum polysaccharides (LBPs) were the first macromolecules reported to mitigate liver fibrosis in carbon tetrachloride (CCl4)-treated mice. Herein, a neutral peptidoglycan, named as LBPW, was extracted from the fruit of Lycium barbarum. In this study, we investigated the hepatoprotective mechanisms of LBPW. CCl4-induced liver fibrosis mice were administered LBPW (50, 100, 200 mg ·kg-1 ·d-1, i.p.) or (100, 200, 300 mg· kg-1 ·d-1, i.g.) for 6 weeks. We showed that either i.p. or i.g. administration of LBPW dose-dependently attenuated liver damage and fibrosis in CCl4-treated mice. Pharmacokinetic analysis showed that cyanine 5.5 amine (Cy5.5)-labeled LBPW (Cy5.5-LBPW) could be detected in the liver through i.p. and i.g. administration with i.g.-administered Cy5.5-LBPW mainly accumulating in the intestine. In TGF-β1-stimulated LX-2 cells as well as in the liver of CCl4-treated mice, we demonstrated that LBPW significantly upregulated Smad7, a negative regulator of TGF-β/Smad signaling, to retard the activation of hepatic stellate cells (HSCs) and prevent liver fibrosis. On the other hand, LBPW significantly boosted the abundance of Akkermansia muciniphila (A. muciniphila) and fortified gut barrier function. We demonstrated that A. muciniphila might be responsible for the efficacy of LBPW since decreasing the abundance of this bacterium by antibiotics (Abs) blocked the effectiveness of LBPW. Overall, our results show that LBPW may exert the hepatoprotective effect via rebalancing TGF-β/Smad7 signaling and propagating gut commensal A. muciniphila, suggesting that LBPW could be leading components to be developed as new drug candidates or nutraceuticals against liver fibrosis.

Global epidemiology of acute kidney injury in hospitalised patients with decompensated cirrhosis: the International Club of Ascites GLOBAL AKI prospective, multicentre, cohort study

BACKGROUND

Acute kidney injury (AKI) is a serious complication of cirrhosis. A systematic, global characterisation of AKI occurring in patients with cirrhosis is lacking. We therefore aimed to assess global differences in the characteristics, management, and outcomes of AKI in hospitalised patients with cirrhosis.

METHODS

In this prospective, multicentre, cohort study, we enrolled adults (≥18 years) with decompensated cirrhosis who were hospitalised for a cirrhosis-related complication, with or without AKI, at 65 centres across five continents. We captured AKI prevalence, stage, phenotype, and details on AKI management and clinical course. Universal health coverage index and gross national income per capita were also collected. The primary outcome was 28-day mortality. Multivariable models including demographic and clinical variables, cirrhosis cause, cirrhosis severity, AKI severity, AKI management variables, universal health coverage, and gross national income were used to analyse independent associations with 28-day mortality. Secondary outcomes were AKI classification, progression, and resolution. This study is complete and registered with ClinicalTrials.gov (NCT05387811).

FINDINGS

Between July 1, 2022, and May 31, 2023, we enrolled 3821 patients who were hospitalised for decompensated cirrhosis. Mean age was 57·7 years (SD 13·1), 2467 (64·6%) were men, and 1354 (35·4%) were women. Most patients were White (2128 [55·7%]). 1456 (38·1%, 95% CI 36·6-39·6) of 3821 patients had AKI (943 [64·8%] men and 513 [35·2%] women). Globally, patients presented with similar AKI stages, but patients from North America and Asia had the highest MELD-Na scores at presentation and the highest rates of peak AKI stage 3. Overall, hypovolaemic AKI was the most common phenotype (858 [58·9%] of 1456), followed by HRS-AKI (253 [17·4%]) and acute tubular necrosis (216 [14·8%]). The prevalences of hypovolaemic AKI and HRS-AKI were similar across regions, but acute tubular necrosis was more frequent in Asia (p<0·0001 across regions). Additionally, regional differences in the management of AKI (use of albumin, vasopressors, and diuretics) were found. 335 (28·6%) of 1171 patients with initial AKI stages 1 or 2 had progression to higher stages during hospitalisation. AKI resolved in 862 (59·2%) cases during hospitalisation. 333 (22·9%) patients with AKI had died by 28 days. Multivariable analyses showed that increased age, female sex, presence of ascites, presence of hepatic encephalopathy, increased white blood cell count, increased MELD-Na, hospital-acquired AKI, a lower universal health coverage index (<80), and not being in a high-income country were independently associated with an increased risk of 28-day mortality. Increased serum albumin was associated with a decreased risk of 28-day mortality.

INTERPRETATION

This study found important regional differences in AKI severity, phenotype, management, and outcomes in patients with decompensated cirrhosis. Health-care coverage remains an important driver of survival in patients with cirrhosis and AKI.

A call to action to address the steatotic liver disease public health threat in Barcelona

Despite their high prevalence worldwide, steatotic liver diseases (SLDs) are largely excluded from most non-communicable disease (NCD) guidelines and strategies. We propose policies and strategies to achieve the United Nations Sustainable Development Goal of reducing NCD premature mortality by one-third by 2030. To assess this gap-the exclusion of SLDs from NCD policies-in urban areas, we reviewed Barcelona's strategies for NCD risks (e.g., alcohol, tobacco, healthy food access). We then explored applications of geo-spatial visualisation and whole-of-society approaches (e.g., citizen science engagement) aligned with the World Health Organization (WHO) Best Buys to provide recommendations to address NCDs, generally, and SLDs specifically.

Role of Liver Transplant in Primary and Secondary Liver Malignancies

Hepatocellular carcinoma (HCC) and cholangiocarcinoma are the primary hepatic malignancies with established pathways to transplantation and model for end-stage liver disease (MELD) exception points. Other tumors managed with liver transplantation (LT) include hepatic epithelioid hemangioendothelioma and fibrolamellar HCC. LT for metastatic neuroendocrine tumor has been established with patient selection criteria and a path to MELD exception points. Additionally, recent data on LT for patients with unresectable hepatic colorectal metastases demonstrate increasingly encouraging initial results.

Clinical outcomes, toxic effect, and immune microenvironment changes of drug-eluting bead bronchial arterial chemoembolisation/bronchial arterial chemoembolization combined with immunotherapy in treating elderly patients with non-small cell lung cancer

AIM

Systemic chemotherapy plus immune checkpoint inhibitors (ICIs) are first-line treatment for advanced non-small cell lung cancer (NSCLC). However, elderly patients typically have comorbidities that tend to limit the use of chemotherapy at standard dosage and frequency. Drug-eluting bead bronchial arterial chemoembolisation (DEB-BACE)/bronchial arterial chemoembolization (BACE) represents options in such patients.

MATERIALS AND METHODS

This is a retrospective analysis. We screened all elderly patients (aged ≥70 years) undergoing treatment with immunotherapy plus DEB-BACE/BACE for pathologically confirmed stage III-IV NSCLC with negative driver gene mutations from October 2019 to December 2023 at our hospital. The response was evaluated according to the Response Evaluation Criteria in Solid Tumors version 1.1 criteria.

RESULTS

The final analysis included 46 patients (median age: 76 years; 42 men and 4 women). Eastern Cooperative Oncology Group (ECOG) performance status was either 1 or 2. The median progression-free survival and overall survival were 9.1 months (95% confidence interval [CI]: 8.4-9.9) and 18.2 months (95% CI: 16.5-19.9), respectively, after a median follow-up of 20.3 months (95% CI: 19.5-21.1) in all populations. The most prevalent adverse events (AEs) were myelosuppression (76.1%, 35/46), followed by decreased appetite (71.7%, 33/46), nausea (65.2%, 30/46), and fatigue (54.3%, 25/46). The rate of any grade and grade ≥3 immune-related AEs was 34.8% (16/46) and 6.5% (3/46), respectively. No patients experienced treatment-related deaths, haemoptysis, or unexpected embolisation.

CONCLUSION

DEB-BACE/BACE combined with immunotherapy was effective and well tolerated in elderly patients with advanced NSCLC.

Temporal Trends of Fungal Infections in Cirrhotic Patients: A Retrospective Cohort Study 2016-2020

Background

Patients with cirrhosis are susceptible to infections due to abnormalities in humoral and cell-mediated immunity. Fungal infections are associated with delayed diagnosis and high mortality rates, emphasizing the importance of performing fungal cultures and maintaining elevated levels of suspicion in this patient population.

Methods

This retrospective cohort study analyzes cirrhotic patients readmitted with bacterial and fungal infections and investigates outcomes, including in-hospital mortality and hospital resource utilization. Data was acquired from the Nationwide Readmission Database (NRD) from 2016 to 2020. Total hospital costs were calculated using HCUP Cost-to-Charge Ratio files and adjusted for inflation based on the Consumer Price Index (CPI) for medical care services in the U.S., with 2020 as the reference year. The NRD dataset lacks details like ascitic fluid cell counts, antifungal/antibacterial drugs used, and treatment responses, limiting the clinical insights that can be derived.

Results

The study analyzed 393,195 index hospitalizations. Among these, 102,505 account for 30-day and 157,079 account for 90-day readmissions. The 30-day and 90-day readmissions for spontaneous bacterial peritonitis (SBP) are 8478 and 15,690 respectively. The 30-day and 90-day readmissions for spontaneous fungal peritonitis (SFP) are 3106 and 5798 respectively. The mean age of patients was 57.9 years (standard deviation between 57.7 and 58.1). The mean length of stay (LOS) for SBP at 30 days is 9.4 days, while SFP has ranged from 14.9 to 32.3 days for various fungal infections. Aspergilloses have the longest LOS among SFP. There is an increased rate of mortality as well as hospital charges with SFP compared to SBP (P < 0.001). The 30-day index admission total charges for SBP are $42,258 and SFP are $51,739. The 30-day readmission total charges for SBP are 64, 266 and for SFP 89,913.

Conclusions

There is increased mortality, LOS, and hospital costs for SFP compared to SBP. It is important to consider SFP in the diagnostic workup for patients who do not respond to antibiotics. Early recognition and administration of antifungals can be associated with improved outcomes.

Early living donor liver transplantation for alcohol-associated hepatitis: Status in the era of increasing demand, unmet needs, and future considerations

Hazardous alcohol consumption is the leading cause of liver disease worldwide. Alcohol-associated hepatitis (AH) is an acute and serious presentation of alcohol-associated liver disease that is associated with high short-term mortality. Medical management remains limited to corticosteroid therapy and intensive nutrition but improves survival in <50% of individuals. Liver transplantation (LT) is increasingly recognized as a treatment option for many patients with AH and may lead to greater survival benefits than medical management alone. The rate of waitlistings and LTs for AH has doubled in recent years, especially in the United States. Several studies from the West have reported early LT for AH to be successful, where deceased donor LT is the norm. The challenges of LT in living donor centers, particularly for those with AH, are unique and have previously not been discussed in depth. In this review, we aim to discuss the challenges unique to LDLT with respect to candidate and donor selection, ethical considerations, disparities in LDLT, post-LT alcohol relapse, and measures to prevent them while also addressing the definitions and outcomes of early-living donor liver LT for AH.

New advances in novel pharmacotherapeutic candidates for the treatment of metabolic dysfunction-associated steatohepatitis (MASH) between 2022 and 2024

Metabolic dysfunction-associated steatotic liver disease (MASLD) covers a broad spectrum of profile from simple fatty liver, evolving to metabolic dysfunction-associated steatohepatitis (MASH), to hepatic fibrosis, further progressing to cirrhosis and hepatocellular carcinoma (HCC). MASLD has become a prevalent disease with 25% in average over the world. MASH is an active stage, and requires pharmacological intervention when there is necroptotic damage with fibrotic progression. Although there is an increased understanding of MASH pathogenesis and newly approved resmetirom, given its complexity and heterogeneous pathophysiology, there is a strong necessity to develop more drug candidates with better therapeutic efficacy and well-tolerated safety profile. With an increased list of pharmaceutical candidates in the pipeline, it is anticipated to witness successful approval of more potential candidates in this fast-evolving field, thereby offering different categories of medications for selective patient populations. In this review, we update the advances in MASH pharmacotherapeutics that have completed phase II or III clinical trials with potential application in clinical practice during the latest 2 years, focusing on effectiveness and safety issues. The overview of fast-evolving status of pharmacotherapeutic candidates for MASH treatment confers deep insights into the key issues, such as molecular targets, endpoint selection and validation, clinical trial design and execution, interaction with drug administration authority, real-world data feedback and further adjustment in clinical application.

Geographic Variation Exists in Heart Transplantation for Status One and Two Patients After the 2018 Heart Allocation Policy Change

BACKGROUND

The heart transplant allocation policy change in 2018 was intended to help ameliorate differences in waiting times for heart transplantation across UNOS regions. We sought to examine the regional variability in waitlist times and post-transplant outcomes since these changes were implemented.

METHODS

The adult patients in the United Network for Organ Sharing registry from October 2018 to December 2022 were included. Regional trends in waitlist time, waitlist events, and post-transplant outcomes were assessed. Differences in regional variability of successful transplantation over years since policy change were described.

RESULTS

A total of 8029 patients were included. The cumulative incidence of successful transplant after 30 days was significantly different across regions (p < 0.001). There was no difference in 30-day post-transplant mortality across regions. In each year since the policy change, there continues to be a significant difference in the lowest and highest cumulative incidence of successful transplant at 30 days across regions using difference of difference analysis, suggesting regional variation has not improved over time (p = 0.49).

CONCLUSIONS

Since the allocation policy change, there continues to be significant variation in time to successful transplantation across geographic regions.

Outcomes of Concomitant Laparoscopic Sleeve Gastrectomy and Hiatal Hernia Repair on Gastroesophageal Reflux Disease in Patients with Severe Obesity: A Propensity Score-Matched Analysis

BACKGROUND

Hiatal hernia (HH) is frequent in patients with obesity who have undergone bariatric surgery, but there is controversy about HH repair (HHR) during bariatric surgery. This study aimed to analyze the safety and efficacy of concomitant laparoscopic sleeve gastrectomy (LSG) and HHR in patients with severe obesity.

METHODS

A propensity score-matched analysis was conducted for patients who underwent LSG. Preoperative barium meal, upper endoscopy, and intraoperative findings were used to diagnose HH. The GERD health-related quality of life (GERD-HRQL) questionnaire was used to diagnose gastroesophageal reflux disease (GERD). Patients were divided into two groups: one underwent concomitant LSG with HHR and the other underwent LSG only. HHR was performed by cruroplasty and reconstruction of the phrenoesophageal ligament (PEL). Gastropexy was performed by fixing the gastric tube to the omentum and peripancreatic fascia. Outcomes included blood loss, operative time, postoperative complications, GERD, and percent excess weight loss.

RESULTS

Of the 406 patients included in the study, 203 patients with HH underwent LSG with HHR, while 203 underwent LSG alone. There was significantly longer operative time in the LSG with HHR group, but no statistical difference between the groups regarding postoperative complications, except postoperative GERD. De novo GERD symptoms developed significantly in the LSG only group. These results indicate that concomitant LSG with HHR leads to improvement of GERD and decreases the rate of de novo GERD symptoms.

CONCLUSIONS

HH should be repaired by cruroplasty and reconstruction of the PEM during LSG. HHR helps to improve postoperative GERD symptoms.

Comparison of Bacterial Infections in Patients With Cirrhosis Between Hospitals With and Without Liver Transplant in Catalonia

BACKGROUND AND AIMS

Infections by multidrug resistant (MDR) bacteria are increasing and vary across regions and hospitals. We aimed to assess the epidemiology, prevalence, and outcomes of bacterial infections in patients with decompensated cirrhosis, comparing liver transplant (LT) and non-LT centers in Catalonia.

METHODS

This is a multicenter retrospective study including all patients with decompensated cirrhosis and bacterial infections hospitalised between January 2021 and 2022 from 5 university hospitals in the Barcelona metropolitan area. Two of them were LT centres. Clinical, laboratory, microbiological data, and in-hospital mortality were collected.

RESULTS

A total of 576 infections were reported in 352 patients. LT centers had more health-related infections, recurrent infections, and septic shock than non-LT centers, while there were no differences in cirrhosis severity, acute-on-chronic liver failure (ACLF) or comorbidities. Although the most commonly isolated microorganisms and types of infection were similar in both centers, LT centers had higher rates of extended-spectrum beta-lactamase (12% vs. 6%), carbapenem (3% vs. 0%) and piperacillin-tazobactam resistant bacteria (14% vs. 7%). MDR rate was also higher in LT centers (38% vs. 25%, p = 0.02) and varied across hospitals (18%-42%, p < 0.05). Furthermore, in-hospital mortality was higher in LT centers (20% vs. 10%; p = 0.01). Independent predictors of in-hospital mortality were septic shock, ACLF, Child-Pugh, age, and leukocyte count.

CONCLUSIONS

Our study showed differences in epidemiology, prevalence of MDR infections, and outcomes across university hospitals, particularly between centers with and without LT. Further studies are warranted to unveil the nuances of bacterial infections across different healthcare institutions in Europe and elsewhere.

Development and validation of the national High-Risk Medicine Classification using the Delphi method

BACKGROUND

High-risk medicines (HRMs) are medicines that have a higher risk of causing severe consequences for the patient when used in error.

OBJECTIVE

This study aimed to develop a Finnish High-risk Medicine Classification (FIN-RiskMeds) to support healthcare professionals in HRM risk management.

METHODS

The development of FIN-RiskMeds was coordinated by the Finnish Medicines Agency (Fimea) using the Delphi consensus method. The preliminary list of HRMs was based on an inventory of existing HRM lists, literature, and the expertise of the working group (WG). A three-round Delphi survey with 60 panelists and a public hearing were used to achieve consensus on the content of the classification. The consensus threshold was set at 70 %.

RESULTS

The expert panel agreed on 42 medicines or medicine classes (later 'items') to be included in the FIN-RiskMeds. A 70 % consensus was reached on 30 out of 60 items in Round 1 and on 13 out of 31 items in Round 2a. The strongest consensus was reached for warfarin, methotrexate, and opioids. The serious consequences and key risks of medicines and the medication process were described for all items after Rounds 2b and 3. Based on the WG's decision after a public hearing, the final classification consists of 38 items.

CONCLUSION

This study produced expert consensus-based classifications of HRMs and a comprehensive list of their key risks. HRMs and their risks should be identified across health and social care to prevent potential medication errors. It is necessary to develop medication processes to minimize the risks associated with HRMs.

Combining CEUS and CT/MRI LI-RADS major imaging features: diagnostic accuracy for classification of indeterminate liver observations in patients at risk for HCC

PURPOSE

To determine the diagnostic accuracy of combining CEUS and CT/MRI LI-RADS major imaging features for the improved categorization of liver observations indeterminate on both CT/MRI and CEUS.

MATERIALS AND METHODS

A retrospective analysis using a database from a prospective study conducted at 11 centers in North America and Europe from 2018 to 2022 included a total of 109 participants at risk for HCC who had liver observations with indeterminate characterization (LR3, LR-4, and LR-M) on both CEUS and CT/MRI. The individual CEUS and CT/MRI LI-RADS major features were extracted from the original study and analyzed in various combinations. Reference standards included biopsy, explant histology, and follow-up CT/MRI. The diagnostic performance of the combinations of LI-RADS major features for definitive diagnosis of HCC was calculated. A reverse, stepwise logistical regression sub-analysis was also performed.

RESULTS

This study included 114 observations indeterminate on both CT/MRI and CEUS. These observations were categorized as LR-3 (n = 37), LR-4 (n = 41), and LR-M (n = 36) on CT/MRI and LR-3 (n = 48), LR-4 (n = 36), LR-M (n = 29), and LR-TIV (n = 1) on CEUS. Of them, 43.0% (49/114) were confirmed as HCC, 37.3% (43/114) non-malignant, and 19.3% (22/114) non-hepatocellular malignancies. The highest diagnostic accuracy among the combinations of imaging features was achieved in CT/MRI LR-3 observations, where the combination of CEUS arterial phase hyper-enhancement (APHE) + CT/MRI APHE had 96.7% specificity, 75.0% positive predictive value (PPV), and 86.5% accuracy for HCC.

CONCLUSION

The combination of LI-RADS major features on CT/MRI and CEUS showed higher specificity, PPV, and accuracy compared to individual modalities' assessments, particularly for CT/MRI LR-3 observations.

Absence of Pupillary Reflexes in Pediatric Acute Liver Failure and Neurological Outcome After Liver Transplantation

BACKGROUND

Pediatric Acute Liver Failure (PALF) frequently requires liver transplantation (LTx). The neurological condition can deteriorate rapidly, but the difficulty in assessing the (ir)reversibility of neurological symptoms can hamper therapeutic decision-making, including transplantation. We aimed to determine the association between pupillary reflexes (PR), brain stem reflexes (BSR), radiological signs of brain herniation, and subsequent neurological outcome.

METHODS

We analyzed a retrospective, observational cohort of PALF patients with severe hepatic encephalopathy (grade III-IV), admitted to our national pediatric liver transplantation center between 1993 and 2023. We subdivided the patients into groups with PR present or PR absent. We compared the two groups for pre-treatment neurological and neuro-radiological parameters and related the findings to neurological outcomes.

RESULTS

Survival rate in patients with PR present was higher compared to patients with PR absent [70% (26/37) and 29% (4/14); resp., p = 0.008]. In the absence of PR, neurological outcome could still be favorable after LTx (n = 3/6). Presence or absence of BSR was not related to the outcome in terms of survival or death. Radiologically proven brain herniation was associated with mortality (6/7) or minimally conscious state (1/7), irrespective of undergoing a LTx or not.

CONCLUSIONS

Although absence of PR is associated with a poor prognosis, the neurological outcome can still be favorable after LTx. Radiological signs of brain herniation are strongly associated with mortality or severe neurological outcomes, irrespective of subsequent transplantation. We therefore advocate that absence of PR should be an indication for radiological imaging to assess brain herniation before making major treatment decisions.

Liver cancer in 2021: Global Burden of Disease study

BACKGROUND & AIMS

The epidemiology of adult primary liver cancer continues to evolve, owing to the increasing prevalence of metabolic disease, rising alcohol consumption, advances in vaccination for HBV, and antiviral therapy for HCV. Disparities in care and the burden of liver cancer between populations persist. We assess trends in the burden of liver cancer and contributions by various etiologies across 204 countries and territories from 2010 to 2021.

METHODS

Utilizing the methodological framework of the Global Burden of Disease Study 2021, we analyzed global and regional temporal trends in incidence and mortality, and the contributions of various etiologies of liver disease.

RESULTS

In 2021, there were an estimated 529,202 incident cases and 483,875 deaths related to liver cancer. From 2010 to 2021, global liver cancer incident cases and deaths increased by 26% and 25%, respectively. Age-standardized incidence rates (ASIRs) and death rates (ASDRs) for liver cancer declined globally, but rose in the Americas and Southeast Asia. HBV remained the dominant cause of global incident liver cancer cases and deaths. MASLD (metabolic dysfunction-associated steatotic liver disease) was the only etiology of liver cancer with rising ASIRs and ASDRs. By contrast, ASIRs and ASDRs remained stable for alcohol-related liver cancer, and declined for HBV- and HCV-related liver cancer.

CONCLUSIONS

While age-adjusted incidence and deaths from liver cancer have started to decline, the absolute number of incident cases and deaths continues to increase. Population growth and aging contribute to the observed disconnect in the temporal trends of absolute cases and rates. Disparities remain, and the incidence and mortality associated with MASLD-related liver cancer continue to rise.

IMPACT AND IMPLICATIONS

Liver cancer remains a major cause of death globally, but its causes and burden in various regions are changing. This study highlights that new diagnoses and deaths related to liver cancer continue to rise. Age-adjusted death rates of liver cancer related to viral hepatitis are declining but remain high. By contrast, age-adjusted death rates of liver cancer related to MASLD (metabolic dysfunction-associated steatotic liver disease) are rising. Sustained efforts and resources are needed to eliminate viral hepatitis, reverse current trends in heavy alcohol use, and tackle the metabolic risk factors of MASLD.

Comparative Study of Terlipressin and Noradrenaline as Vasopressors in Patients With Acute-on-chronic Liver Failure and Septic Shock: A Randomized Controlled Trial

BACKGROUND

Sepsis is the most common acute insult in patients with acute-on-chronic liver failure (ACLF), and circulatory failure portends a poor prognosis in them.

AIM

This study aimed to compare terlipressin and noradrenaline as first-line vasopressors in patients with ACLF and septic shock.

METHODS

This prospective, open-label, randomized controlled study was conducted from January 2021 to June 2022 at a tertiary care center. All patients presenting with ACLF as per the chronic liver failure consortium acute on chronic liver failure in cirrhosis study and septic shock were screened. Shock was defined as a mean arterial pressure (MAP) <65 mmHg/systolic blood pressure <90 mmHg. Patients with septic shock nonresponsive to crystalloids/colloids were randomized to receive terlipressin (group I) at 2.6 μg/kg/min and noradrenaline (group II) at 0.1 μg/kg/min. The primary outcome was an MAP >65 mmHg at 6 h. The secondary outcomes were 3-, 7-, 14-, and 28-day mortality, duration of hospital stay, cumulative dose of drug, and new events such as upper gastrointestinal bleed, acute kidney injury, jaundice, and hepatic encephalopathy within 28 days.

RESULTS

A total of 70 patients were randomized to group I (n = 35) and group II (n = 35). According to per-protocol analysis, a higher number of patients achieved an MAP > 65 mmHg at 6 h in group II (n = 23/31, 74%) than in group I (5/34, 14%) (P < 0.001). The 3-and 7-day mortality was significantly higher in group I than in group II, with no difference at 14 and 28 days. The 28-day mortality was highest in ACLF grade-3 in both group II (22/25, 88%) and group I (15/20, 75%).

CONCLUSION

Terlipressin did not prove to be noninferior to norepinephrine, and therefore, norepinephrine should be the first-line vasopressor in ACLF patients with septic shock. The mortality rate was highest in ACLF grade-3 patients in both the groups, irrespective of the initial response to vasopressors. This indicates that holistic management of these patients is most important.

Differential Characteristics and Survival Outcomes of Patients With Cirrhosis According to Underlying Liver Aetiology

BACKGROUND AND AIMS

Updated data on the survival of patients with cirrhosis are limited, especially for subgroups by specific liver disease aetiology. To inform practice, future modelling studies, and public health planning, our study aimed to provide updated and granular data on survival outcomes of patients with cirrhosis stratified by liver disease aetiology. We also assessed their changes over time.

METHODS

We analysed 8726 consecutive adult patients with cirrhosis who presented at Stanford university medical center during 1/2005-1/2022.

RESULTS

8726 Patients had the following etiologies: hepatitis C virus (HCV) (28.1%), hepatitis B virus (HBV) (4.8%), alcohol-associated (ALD, 33.3%), metabolic-associated steatotic liver disease (MASLD) (9.5%), autoimmune (9.6%), cryptogenic (8.2%) and other etiologies (6.5%). Patients with cryptogenic cirrhosis had the lowest overall 5-, 10-, and 15-year cumulative survival (57.5%, 34.3% and 21.4%), as well as for liver and nonliver-related death, followed by ALD, MASLD, HCV, and autoimmune, while HBV patients had the best survival (86.0%, 70.1% and 65.1%), respectively. On multivariable Cox regression, cryptogenic cirrhosis (vs. HBV) was associated with the highest risk of all-cause death (aHR: 2.24, 95% CI 1.67-3.00), followed by MASLD and ALD (all p < 0.001). Post-2010 time was associated with a 33% lower risk of all-cause death (p = 0.0011); While in the post-2010 period, MASLD (vs. HBV) was associated with the highest risk of all-cause death (aHR: 1.92, 95% CI 1.32-2.80, p < 0.001) followed by cryptogenic and ALD.

CONCLUSIONS

Survival outcomes in patients with cirrhosis varied by aetiology and have changed over time, which should be taken into account for future practice guidelines and modelling studies.

The importance of patient engagement in the multimodal treatment of MASLD

Metabolic dysfunction-associated steatotic liver disease (MASLD) is often regarded in society as a disease caused by personal lifestyle and dietary choices. Healthcare providers who have empathy and are able to explain the disease trajectory can better engage with people with MASLD and actively work with them to improve their metabolic health on a sustainable basis. Non-invasive tests can assist in this process, but healthcare providers must ensure they explain their advantages and limitations. Discussing and setting lifestyle goals are priorities before initiating specific pharmacological treatment, since living a healthy lifestyle will remain the backbone of the multimodal management of MASLD. In this review, we discuss challenges and opportunities to actively engage with people living with MASLD in a multimodal treatment framework as a healthcare provider.

Mediative role of body mass index in cardiorespiratory fitness-associated vascular remodeling in youth

BACKGROUND

Data on fitness-associated arterial remodeling in children is limited. We assessed the relation between cardiorespiratory fitness (CRF) and intima-media thickness (IMT), diameter, IMT:diameter-ratio (IDR), and tensile stress of the common carotid artery (CCA) in 697 healthy German schoolchildren. Further, we explored how body mass index (BMI) may influence these associations.

METHODS

We measured the vascular parameters with a high-resolution ultrasound device. We determined CRF using the FITNESSGRAM® PACER test and calculated each child's allometrically scaled peak oxygen uptake capacity (VO2peak).

RESULTS

VO2peak, reflecting CRF, showed positive direct effects on IMT (girls: p < 0.001; boys: p = 0.02) and diameter in girls (p < 0.001). Considering BMI as a mediator, higher CRF was indirectly linked to decreases in IMT (girls: p = 0.04; boys: p = 0.02) and diameter (both p < 0.001), reflecting a competitive mediation. CRF indirectly mitigated the BMI-associated decrease in IDR (both p < 0.001) and increase in tensile stress (both p < 0.001) without affecting any of these parameters directly.

CONCLUSION

CRF appears to be linked to uniform arterial remodeling with balanced hemodynamics and to further alleviate BMI-associated, potentially adverse vascular alterations, highlighting its significant role in cardiovascular health in youth.

IMPACT

Data on CRF-associated arterial remodeling in youth is limited. Higher VO2peak, reflecting higher CRF, was positively associated with IMT in girls and boys and diameter in girls. These direct effects were counteracted by the indirect BMI-mediated effect of CRF on IMT and diameter, reflecting a competitive mediation. A higher CRF indirectly mitigated the BMI-associated decrease in IDR and increase in tensile stress without directly affecting any of these parameters. Our findings indicate homogenous remodeling and balanced hemodynamics with increasing CRF-and opposite effects with increasing BMI.

Rethinking Antibiotic Prophylaxis for Spontaneous Bacterial Peritonitis in Patients With Cirrhosis: First, Do No Harm

Antibiotic prophylaxis for spontaneous bacterial peritonitis (SBPPr) in patients with cirrhosis has been considered the standard of care since the 1990s and is currently recommended by several major gastroenterological societies. However, the evidence that supports this practice is weak, and there is no clear mortality benefit. The unintended consequences of this strategy are not insignificant, both at the patient and population levels. Recent evidence suggests that SBPPr may even cause harm. Since the widespread implementation of SBPPr 3 decades ago, our overall approach to antibiotic use has shifted. We now recognize the growing threat of antimicrobial resistance, the potential harms of antibiotics, and the vital role of antimicrobial stewardship. In light of recent developments and evidence, there is an urgent need for infectious diseases, antimicrobial stewardship, and hepatology leaders to collaborate in development of an updated and cohesive approach to SBPPr.

Mitochondrial Dysfunction as a Pathogenesis and Therapeutic Strategy for Metabolic-Dysfunction-Associated Steatotic Liver Disease

Metabolic-dysfunction-associated steatotic liver disease (MASLD) has emerged as a significant public health concern, attributed to its increasing prevalence and correlation with metabolic disorders, including obesity and type 2 diabetes. Recent research has highlighted that mitochondrial dysfunction can result in the accumulation of lipids in non-adipose tissues, as well as increased oxidative stress and inflammation. These factors are crucial in advancing the progression of MASLD. Despite advances in the understanding of MASLD pathophysiology, challenges remain in identifying effective therapeutic strategies targeting mitochondrial dysfunction. This review aims to consolidate current knowledge on how mitochondrial imbalance affects the development and progression of MASLD, while addressing existing research gaps and potential avenues for future research. This review was conducted after a systematic search of comprehensive academic databases such as PubMed, Embase, and Web of Science to gather information on mitochondrial dysfunction as well as mitochondrial-based treatments for MASLD.

Modification of biopharmaceutical parameters of flavonoids: a review

Flavonoids are natural organic compounds that are derivatives of diphenylpropane. This group of polyphenols can be found in multiple natural sources and they exhibit a variety of biological effects. Despite the wide array of beneficial properties, the development of drugs based on these compounds is hindered by their low bioavailability. Although the substantial body of information available on strategies to enhance the solubility and bioavailability of flavonoids, this knowledge remains fragmented. Therefore, the aim of this study was to consolidate and systematize scientific data on methods for increasing the solubility and bioavailability of flavonoid compounds without changing their initial molecular structures. Throughout the investigation, it was determined that the most prevalent methods for increasing solubility and bioavailability include co-crystallization, formation of phospholipid and inclusion complexes, and the creation of nanostructures. Although there were no pronounced differences observed in enhancing solubility, the impact of these methods on pharmacokinetic parameters was established. It was found that the production of inclusion complexes and nanostructures leads to the greatest increase in the area under the pharmacokinetic curve by an average of 4.2 and 3.7 times, respectively. The least effect was noted for phytosomes, where this parameter for the modified forms exceeded the initial value by only 1.7 times. Phospholipid complexes exhibited a longer average half-elimination time than all other modifications, achieving a 2.1-fold increase. For nanostructures and micelles, a substantial increase in maximum concentration of the active substance in blood plasma was observed, reaching an average of 5.4 times for both types of modifications. During the systematization and generalization of the data, a high level of heterogeneity in solubility assessment methods across various studies was revealed, complicating comparisons of original data obtained by different researchers. The findings of this review are crucial for researchers investigating the bioavailability of flavonoid compounds and will facilitate the selection of the most effective methods based on the desired outcomes for solubility and bioavailability.

Hepatobiliary Manifestations in Thalassemia Patients: A Narrative Review

Thalassemia is one of the most common inherited blood disorders worldwide. This defect causes a disproportionate ratio of α- and β-globin chains resulting in ineffective erythropoiesis leading to increased iron absorption. In patients where the imbalance between α and β globin chains is great they are dependent on blood transfusions for survival. This results in transfusional iron overload but also comes with additional risks such as transfusion-transmissible viral infections like hepatitis B and C. This can lead to various complications like liver fibrosis, cirrhosis and hepatocellular carcinoma, which are important causes with morbidity and mortality in patients of thalassemia today. These hepatobiliary manifestations and their management are briefly discussed in this review. Understanding hepatobiliary complications in thalassemia is vital for optimizing patient care.

Nursing care for patients with liver cirrhosis undergoing surgery for esophageal variceal bleeding in an integrated healthcare system

BACKGROUND

Globally, Liver cirrhosis is the 14th leading cause of death and poses a significant threat to human health.

AIM

To investigate the effects of a multidisciplinary collaboration model on postoperative recovery and psychological stress in patients with liver cirrhosis undergoing esophageal variceal bleeding (EVB) surgery within an integrated healthcare system.

METHODS

Between January 2022 and March 2024, a total of 180 patients with cirrhosis and EVB were admitted and randomly assigned to either a control group (standard care) or an observation group (standard care plus the multidisciplinary collaboration model), with 90 patients in each group. Postoperative recovery indicators (time to symptom improvement, time to start eating, time to bowel sound recovery, time to first flatus, and hospital stay), psychological stress responses [self-rating anxiety scale (SAS); self-rating depression scale (SDS)], subjective well-being, and incidence of complications were compared between the two groups.

RESULTS

Compared to the control group, the observation group showed earlier symptom improvement, earlier return to eating, bowel sound recovery, first flatus, and a shorter hospital stay. Pre-intervention SAS and SDS scores were not significantly different between the groups, but post-intervention scores were significantly lower in the observation group. Similarly, there was no significant difference in the subjective well-being scores before the intervention between the two groups. After the intervention, both groups showed improved scores, with the observation group scoring significantly higher than the control group.

CONCLUSION

The observation group also had a lower incidence of complications. Therefore, for patients with liver cirrhosis undergoing EVB surgery, a multidisciplinary collaboration model within an integrated healthcare system can promote early postoperative recovery, reduces psychological stress, improves subjective well-being, and reduces complications and rebleeding.

Assessing Clinician Engagement with a Passive Clinical Decision Support System for Liver Fibrosis Risk Stratification in a Weight Management Clinic

OBJECTIVE

Metabolic dysfunction-associated steatotic liver disease (MASLD) is common in obesity. Guidelines recommend liver fibrosis risk stratification with tools such as Fibrosis-4 (FIB-4) index, liver stiffness measurement with vibration-controlled transient elastography (VCTE) and/or hepatology referral for elevated FIB-4. Despite recommendations, implementation remains limited. Using mixed methods, we evaluated a three-strategy implementation bundle to improve fibrosis risk stratification-a FIB-4-based electronic health record embedded clinical decision support system (CDSS), educational outreach, and internal facilitation in a weight management clinic.

METHODS

The primary outcome was penetration: the proportion of patients with elevated FIB-4 completing VCTE or hepatology referral. We compared rates, pre and post activation of implementation bundle using Fischer's exact test. Semi-structured provider interviews, guided by the i-PARIHS framework, assessed acceptability and feasibility three months post-implementation.

RESULTS

In the pre-activation phase, 880/3933 (22.4%) weight management visits had the necessary labs to calculate automated FIB-4 scores with 128 elevated scores. In the post-activation phase, 2513/4,634 weight management visits (54.2%) had automated FIB-4 scores; with 234 elevated score. Pre-activation, there were no VCTE and 2 hepatology referrals. Post-activation, there were 3 VCTE referrals and 2 hepatology referrals (Fischer's exact test p-value=1.00). Providers cited shared responsibility with primary care, low awareness and trust in risk-stratification tools, workflow challenges, and competing demands as barriers. Educational outreach and facilitation improved CDSS engagement, while technical issues reduced it.

CONCLUSION

This implementation strategy bundle did not achieve meaningful MASLD fibrosis risk stratification. EHR based CDSS shows promise but requires alignment with provider priorities, seamless workflow integration, and robust technical infrastructure.

Macrophage PKM2 depletion ameliorates hepatic inflammation and acute liver injury in mice

Introduction

Pyruvate kinase M2 (PKM2), the rate-limiting enzyme of glycolysis, plays a critical role in macrophage activation and a broad spectrum of chronic liver diseases. However, whether PKM2 contributes to the pathogenesis of acute liver injury (ALI) remains largely unexplored.

Methods

PKM2 expression was assessed in human and mouse ALI livers. Macrophage-specific PKM2 knockout mice were challenged by two independent ALI models, induced by acetaminophen (APAP) and lipopolysaccharide/D-galactosamine (LPS/D-GalN), to explore the role and regulatory mechanism of macrophage PKM2 in ALI progression.

Results

By bioinformatic screening and analysis of ALI liver, we found that PKM2 was significantly upregulated in the liver tissues of ALI patients and mice. Immunofluorescence staining further demonstrated that PKM2 was markedly upregulated in macrophages during ALI progression. Notably, macrophage PKM2 depletion effectively alleviated APAP- and LPS/D-GalN-induced ALI, as demonstrated by ameliorated immune cells infiltration, pro-inflammatory mediators, and hepatocellular cell death. PKM2-deficient macrophages showed M2 anti-inflammatory polarization in vivo and in vitro. Furthermore, PKM2 deletion limited HIF-1α signaling and aerobic glycolysis of macrophages, which thereby attenuated macrophage pro-inflammatory activation and hepatocyte injury. Pharmacological PKM2 antagonist efficiently ameliorated liver injury and prolonged the survival of mice in APAP-induced ALI model.

Discussion

Our study highlights the pivotal role of macrophage PKM2 in advancing ALI, and therapeutic targeting of PKM2 may serve as a novel strategy to combat ALI.

Acute liver injury and diffuse subcutaneous pneumatosis following compound paracetamol and amantadine hydrochloride tablets poisoning: a case report

Introduction

Severe acute poisoning from Compound paracetamol and Amantadine hydrochloride tablets can result in various complications, including acute liver injury, central nervous system reactions, and gastrointestinal symptoms.

Case summary

A 15-year-old previously healthy female ingested 108 Compound paracetamol and Amantadine hydrochloride tablets. She presented to the emergency department with severe nausea, vomiting, abdominal pain, and distension, along with confusion. Emergency interventions, including gastric lavage and endotracheal intubation for respiratory support, were initiated. She was subsequently transferred to the intensive care unit for advanced life support, including nasogastric tube, hemoperfusion, and hemodialysis. During treatment, she developed coagulation abnormalities, liver injury, acute gastric mucosal bleeding, electrolyte imbalances, and psychiatric symptoms. A computed tomography (CT) scan revealed diffuse subcutaneous pneumatosis extending to the neck, anterior chest wall, thoracic cavity, and mediastinum. Following aggressive treatment, the patient was successfully discharged on the seventh day after the overdose.

Conclusion

Acute liver injury and diffuse subcutaneous pneumatosis affecting multiple regions, caused by the ingestion of a large quantity of Compound paracetamol and Amantadine hydrochloride tablets, is a rare occurrence. With early gastric lavage, blood purification, and supportive therapy, the patient was successfully treated and discharged.

Targeting Metabolism: Innovative Therapies for MASLD Unveiled

The recent introduction of the term metabolic-dysfunction-associated steatotic liver disease (MASLD) has highlighted the critical role of metabolism in the disease's pathophysiology. This innovative nomenclature signifies a shift from the previous designation of non-alcoholic fatty liver disease (NAFLD), emphasizing the condition's progressive nature. Simultaneously, MASLD has become one of the most prevalent liver diseases worldwide, highlighting the urgent need for research to elucidate its etiology and develop effective treatment strategies. This review examines and delineates the revised definition of MASLD, exploring its epidemiology and the pathological changes occurring at various stages of the disease. Additionally, it identifies metabolically relevant targets within MASLD and provides a summary of the latest metabolically targeted drugs under development, including those in clinical and some preclinical stages. The review finishes with a look ahead to the future of targeted therapy for MASLD, with the goal of summarizing and providing fresh ideas and insights.

Research Progress on the Mechanism of Bile Acids and Their Receptors in Depression

Depression, a highly prevalent mental disorder worldwide, arises from multifaceted interactions involving neurotransmitter imbalances, inflammatory responses, and gut-brain axis dysregulation. Emerging evidence highlights the pivotal role of bile acids (BAs) and their receptors, including farnesoid X receptor (FXR), Takeda G protein-coupled receptor 5 (TGR5), and liver X receptors (LXRs) in depression pathogenesis through modulation of neuroinflammation, gut microbiota homeostasis, and neural plasticity. Clinical investigations demonstrated altered BA profiles in depressed patients, characterized by decreased primary BAs (e.g., chenodeoxycholic acid (CDCA)) and elevated secondary BAs (e.g., lithocholic acid (LCA)), correlating with symptom severity. Preclinical studies revealed that BAs ameliorate depressive-like behaviors via dual mechanisms: direct CNS receptor activation and indirect gut-brain signaling, regulating neuroinflammation, oxidative stress, and BDNF/CREB pathways. However, clinical translation faces challenges including species-specific BA metabolism, receptor signaling complexity, and pharmacological barriers (e.g., limited blood-brain barrier permeability). While FXR/TGR5 agonists exhibit neuroprotective and anti-inflammatory potential, their adverse effects (pruritus, dyslipidemia) require thorough safety evaluation. Future research should integrate multiomics approaches and interdisciplinary strategies to develop personalized BA-targeted therapies, advancing novel treatment paradigms for depression.

Gut microbiota-derived UDCA enhanced by metformin inhibits FXR to activate autophagy against MCD diet-induced NAFLD in mice

Nonalcoholic fatty liver disease (NAFLD), a prevalent chronic liver disease, poses a substantial global health burden. Metformin is known for its protective effects in NAFLD, but the role of gut microbiota in the underlying mechanisms remains unclear. In this study, metformin was found to mitigate methionine-choline deficient (MCD) -diet induced NAFLD through reshaping the gut microbiota to increase ursodeoxycholic acid (UDCA) level, thereby inhibiting farnesoid X receptor (FXR) accompanied with activated autophagy. Specifically, using dirty cage experiments and 16S rRNA sequencing, it identified that metformin could reshape microbiota to release liver injury as confirmed by the results of histopathology and biochemical index detection. Furthermore, the bile acids were found to be altered by metformin, in which, the UDCA, a FXR natural inhibitor, was observed a significantly increase. Meanwhile, the inhibited FXR and activated autophagy in metformin-treated mice were captured using western blot, qRT-PCR and immunofluorescence analysis. In addition, the benefit of UDCA against NAFLD was demonstrated in UDCA treated mice. Further investigation with FXR siRNA introduced to HepG2 cells revealed that inhibiting FXR can reduce oleic acids induced cell injury with the autophagy activation. In conclusion, this study highlights metformin's potential to ameliorate NAFLD by reshaping gut microbiota, thereby upregulating UDCA in the liver and restoring cholesterol synthesis capacity, possibly via inhibiting FXR to activate autophagy.

Shaping the future of inflammatory bowel disease: a global research agenda for better management and public health response

Inflammatory bowel disease (IBD) is a growing global health challenge affecting more than 7 million people worldwide. With increasing prevalence across all age groups, including children and adolescents, IBD places substantial strain on health-care systems and society, resulting in high direct medical costs, lost productivity and reduced quality of life. Despite therapeutic advances, suboptimal disease control and delays in timely diagnosis and adequate treatment persist. Regional disparities in health-care access contribute to these challenges, especially in low-income countries. Addressing these inequities is crucial for improving global IBD outcomes. Using a Delphi methodology, experts from clinical care, research, public health and advocacy (including patient representation) identified priorities across six domains (37 statements in total): epidemiology, care models, treatment strategies, education and awareness, patient and community engagement, and leadership to promote health equity. These priorities emphasize quantifying the burden of IBD, addressing health-care disparities, validating care models, exploring novel treatments, advancing education, engaging patients and advocating for health equity policies. The comprehensive approach seeks to optimize care models, promote patient engagement and ensure equitable access to health care. The identified priorities serve as a guide for both clinical and non-clinical researchers, and funders dedicated to IBD-related initiatives, fostering international collaboration to improve IBD management and reduce its impact globally.

Glycodeoxycholic Acid Inhibits Primary Bile Acid Synthesis With Minor Effects on Glucose and Lipid Homeostasis in Humans

BACKGROUND

Bile acids play vital roles in control of lipid, glucose, and energy metabolism by activating Takeda G protein-coupled receptor 5 and Farnesoid X receptor, the latter promoting production of the endocrine-acting fibroblast growth factor 19 (FGF19). Short-term administration of single bile acids has been reported to enhance plasma levels of GLP-1 and to enhance energy expenditure. However, prolonged bile acid supplementation (eg, of chenodeoxycholic acid for gallstone dissolution) has been reported to have adverse effects.

STUDY DESIGN

In this proof-of-concept study, we assessed the safety and metabolic effects of oral glycine-conjugated deoxycholic acid (GDCA) administration at 10 mg/kg/day using regular and slow-release capsules (mimicking physiological bile acid release) over 30 days in 2 groups of each 10 healthy lean men, respectively.

MAIN FINDINGS

GDCA increased postprandial total bile acid and FGF19 concentrations while suppressing those of the primary bile acids chenodeoxycholic acid and cholic acid. Plasma levels of 7α-hydroxy-4-cholesten-3-one were reduced, indicating repressed hepatic bile acid synthesis. There were minimal effects on indices of lipid, glucose, and energy metabolism. No serious adverse events were reported during GDCA administration in either capsule types, although 50% of participants showed mild increases in plasma levels of liver transaminases and 80% (regular capsules) and 50% (slow-release capsules) of participants experienced gastrointestinal adverse events.

CONCLUSION

GDCA administration leads to elevated FGF19 levels and effectively inhibits primary bile acid synthesis, supporting therapy compliance and its effectiveness. However, effects on lipid, glucose, and energy metabolism were minimal, indicating that expanding the pool of this relatively hydrophobic bile acid does not impact energy metabolism in healthy subjects.

Management of hepatic encephalopathy following transjugular intrahepatic portosystemic shunts: Current strategies and future directions

Transjugular intrahepatic portosystemic shunts (TIPSs) are generally used for the management of complications of portal hypertension in patients with decompensated cirrhosis. However, hepatic encephalopathy (HE), which impairs neuropsychiatric function and motor control, remains the primary adverse effect of TIPS, limiting its utility. Prompt prevention and treatment of post-TIPS HE are critical, as they are strongly associated with readmission rates and poor quality of life. This review focuses on the main pathophysiological mechanisms underlying post-TIPS HE, explores advanced biomarkers and predictive tools, and discusses current management strategies and future directions to prevent or reverse HE following TIPS. These strategies include preoperative patient assessment, individualized shunt diameter optimization, spontaneous portosystemic shunt embolization during the TIPS procedure, postoperative preventive and therapeutic measures such as nutrition management, medical therapy, fecal microbiota transplantation, and stent reduction.

The Survival Benefit of Accepting an Older Donor Lung Transplant Compared With Waiting for a Younger Donor Offer

BACKGROUND

Donor pool expansion is critical as lung candidates suffer high mortality, yet older donor lungs remain underutilized. We evaluated whether accepting an older donor (defined 4 ways: donor age 30-39, 40-49, 50-59, or 60-69 y) lung transplant was associated with a survival benefit over waiting for a younger donor offer.

METHODS

Adult candidates who received a lung offer were identified using Scientific Registry of Transplant Recipients data, 2015-2022. Offers were categorized by donor age and candidate lung allocation score (LAS; <40, 40-55, >55). Postoffer mortality was compared between candidates for whom the offer was accepted ("acceptors") versus declined ("decliners") within each age-LAS category using weighted Cox regression.

RESULTS

A total of 21 426 candidates received an offer from a donor age ≥30 y; 11 679 accepted. For LAS >55 candidates, a survival benefit was observed for acceptors of donors ages 30-39 y (weighted hazard ratio [wHR] of mortality: 0.450.520.59), 40-49 y (wHR: 0.610.700.79), and 50-59 y (wHR: 0.670.770.88); P < 0.001. For candidates with LAS 40-55, results suggest a survival benefit of accepting lung offers from donors age 30-39 y (wHR: 0.770.870.99) and 40-49 y (wHR: 0.760.870.99); P = 0.03. However, for candidates with LAS <40, a survival benefit was not observed for accepting any older donor transplant, with possible harm in accepting an age 50+ donor offer.

CONCLUSIONS

Compared with declining and waiting for a younger donor offer, accepting an older donor lung transplant was associated with a survival advantage in candidates with high LAS in the precontinuous distribution era. Decision makers should consider these findings while recognizing potential changes in waiting time dynamics in the current era.
