Hepatic ischemia–reperfusion (HIR) injury impairs outcomes post–liver transplantation. Therefore, we aimed to investigate the role and mechanism of miR-381-3p in HIR.

The study enrolled 150 healthy controls, 82 non-HIR-injured patients, and 68 patients with HIR injury following liver transplantation. Clinical data were analyzed. Multivariate analysis identified HIR risk factors; the predictive value of miR-381-3p was assessed via receiver operating characteristic analysis. An in vitro hypoxia/reoxygenation (H/R) model was established and employed. The cellular effects of miR-381-3p and JAK2 were evaluated using CCK-8, flow cytometry, ELISA, luciferase, RIP, and bioinformatics.

Serum miR-381-3p was significantly elevated in HIR compared with the other groups. miR-381-3p was the strongest independent HIR risk factor, which was confirmed by receiver operating characteristic analysis. H/R upregulated miR-381-3p. Inhibiting miR-381-3p counteracted H/R-induced decreased viability and increased apoptosis, inflammation, and oxidative stress. miR-381-3p directly bound to and suppressed JAK2 via its 3′ untranslated region (validated by luciferase and RIP). Transfection of si-JAK2 abolished the protective effects of miR-381-3p inhibition.

miR-381-3p exacerbates post-transplant HIR by directly targeting JAK2, amplifying inflammation and oxidative stress. Thus, our findings nominate serum miR-381-3p as a promising non-invasive biomarker and suggest its potential as a therapeutic target for mitigating HIR injury.

Congenital portosystemic shunts (CPSS) are rare vascular anomalies characterized by abnormal communication between the portal and systemic venous systems, resulting in partial or complete diversion of portal blood away from the liver. These shunts can give rise to a broad spectrum of clinical manifestations, including hyperammonemia (with or without encephalopathy), hepatopulmonary syndrome, and portopulmonary hypertension. Notably, these complications often occur in the absence of portal hypertension. Advances in diagnostic imaging, particularly Doppler ultrasound, computed tomographic angiography, and magnetic resonance imaging, have enhanced the early detection and classification of CPSS. Treatment approaches vary depending on shunt type and clinical severity and may include interventional closure via embolization or surgical ligation. Most persistent or symptomatic shunts require immediate intervention. Recent studies have also identified potential genetic and embryological mechanisms contributing to CPSS development, offering new insights into their pathogenesis. This review aims to summarize current knowledge on the epidemiology, pathophysiology, clinical presentation, diagnostic evaluation, and management of CPSS, and to highlight their consideration in patients with hepatic encephalopathy or unexplained liver disease.

Insulin resistance is a common extrahepatic manifestation of hepatitis C virus (HCV) infection (HCVi), but its mechanism is poorly understood. While systemic insulin resistance is documented, portal insulin dynamics, a key regulator of hepatic metabolism, remain unexplored. This study aimed to investigate the relationship between insulin, the gut-liver axis, and immunometabolic changes in patients with HCV.

HCV patients were evaluated before (HCVi; n = 29) and after sustained virologic response (SVR) achieved with sofosbuvir/velpatasvir treatment (SVR, n = 23) (NCT02400216). Liver biopsies, portal blood, and peripheral blood were collected at both phases. Statistical analyses were conducted using Wilcoxon rank-sum tests, Mann-Whitney tests, and Pearson’s correlation coefficients to assess differences and associations across insulin, glucose, cytokines, metabolites, immune cells, and hepatic liver transcriptomics to elucidate impaired insulin homeostasis in HCVi.

HCV patients had significantly reduced portal insulin compared to SVR (p = 0.02), while peripheral insulin, portal glucose, and peripheral glucose remained unchanged. Portal insulin correlated positively with proinflammatory cytokines and vascular injury markers and negatively with CD8/CD62L/CD45RA/CD3 cells (naive cytotoxic T-cells) and non-standard nucleotides. Hepatic transcriptomic analysis revealed portal insulin correlated positively with immune and negatively with amino acid pathways, reflecting insulin’s role in the perturbations of immunometabolism during HCVi.

Lower portal insulin during HCVi is associated with changes consistent with altered pancreatic insulin secretion and decreased hepatic insulin extraction. The observed correlations support a potential relationship between the immune response and insulin dynamics, indicating an interplay between the immune system, metabolism, and insulin in HCVi, with clinical implications for the management of dysglycemia.

Tenofovir alafenamide (TAF) has demonstrated comparable efficacy to tenofovir disoproxil fumarate (TDF), with improved renal and bone safety, in Chinese participants with chronic hepatitis B enrolled in two Phase 3 trials. This study aimed to evaluate the long-term virologic efficacy, serological and biochemical responses, resistance, and renal and bone safety of TAF over eight years in this population.

Participants completing the three-year double-blind phase were eligible to receive open-label TAF 25 mg/day for up to an additional five years (totaling eight years). Analyses of viral suppression (HBV DNA < 29 IU/mL), alanine aminotransferase normalization, serological responses, resistance surveillance, and safety outcomes were conducted.

Among 334 enrolled participants, 212 of 227 participants randomized to TAF continued open-label TAF (TAF-TAF), and 99 of 107 participants on TDF switched to open-label TAF (TDF-TAF). At Year 8, 79.3% (180/227) and 78.5% (84/107) of participants in the TAF-TAF and TDF-TAF groups, respectively, achieved viral suppression (missing = failure); rates increased to 95.2% (180/189) and 95.5% (84/88) when excluding missing data. Alanine aminotransferase normalization rates remained high and comparable between groups. Serologic response rates continued to increase over time, with higher rates observed in the TAF-TAF group. Estimated glomerular filtration rate (by Cockcroft-Gault) and hip/spine bone mineral density remained stable in the TAF-TAF group through eight years; the small declines in these renal and bone parameters observed during double-blind TDF treatment improved after switching to open-label TAF. No resistance to TAF was detected.

Long-term TAF treatment demonstrated durable virologic efficacy, sustained biochemical and serological responses, and favorable renal and bone safety over eight years in Chinese participants with chronic hepatitis B.

Breast cancer (BCA) is one of the most common cancers worldwide, with a high rate of incidence and mortality. This review provides global information on BCA therapy using curcumin. Chemotherapy, as an effective treatment for different stages of BCA, and curcumin, generally regarded as safe compound and an alternative to synthetic drugs, have been described for the treatment of BCA. A few parameters, including nano-curcumin versus bulk curcumin and its encapsulated form versus its corresponding free form, have been discussed. Curcumin, a safe and edible compound with antitumor properties, is a promising medicinal compound for the treatment of BCA. Encapsulation of curcumin enhances its stability and anticancer efficiency. Nano-curcumin exhibits superior properties when compared to its bulk counterparts, leading to notable interactions and effects.

Infectious diarrhea is a gastrointestinal illness that results in around 1.7 billion cases and 525,000 deaths annually, particularly among children under five, according to the World Health Organization. While some Cameroonian medicinal plants show promise for treating diarrhea, many plants are used without established scientific evidence of their efficacy. These plants include Tithonia diversifolia (T. diversifolia) and Solanum torvum (S. torvum), which are traditionally used to treat diarrheal symptoms. This study sought to investigate the anti-Shigella activity of leaf extracts from T. diversifolia and S. torvum.

Extracts from T. diversifolia and S. torvum were obtained by successive maceration in solvents of increasing polarity, including hexane, dichloromethane, ethyl acetate, methanol, and water. The as-prepared extracts (10) were evaluated for antibacterial activity against selected Shigella species using an in vitro experiment. The mode of action of the bioactive extracts was determined in Shigella through growth kinetic analysis.

Hexane extract from S. torvum (St-HEX-F) and dichloromethane extract from T. diversifolia (Td-DCM-F) inhibited the growth of Shigella flexneri NR-518 and Shigella boydii NR-521 with minimum inhibitory concentration (MIC) values of 500 and 1,000 µg/mL, respectively. Shigella flexneri and Shigella boydii were the most sensitive strains, whereas Shigella sonnei was the most resistant strain. Bacterial growth kinetics revealed that St-HEX-F and Td-DCM-F are bacteriostatic at MIC and bactericidal at 2×MIC and 4×MIC.

Extracts from T. diversifolia and S. torvum possess anti-Shigella activity and could be used as a potential source of active ingredients for developing new treatments against diarrhea caused by multidrug-resistant Shigella.

Gliomas remain a major challenge in brain cancer treatment. Although genetic mutations have been widely studied, recent research indicates that epigenetic changes, which alter gene activity without changing the DNA sequence, also contribute significantly to tumor growth and treatment resistance. This review seeks to elucidate the principal drivers and modulators of brain tumor development, emphasizing the complex interaction between tumor metabolism and epigenetic regulation. It highlights how metabolic intermediates influence chromatin structure and transcriptional events driving glioma progression. Metabolic intermediates, such as acetyl-CoA and S-adenosylmethionine, serve as essential epigenetic cofactors, directly impacting chromatin structure and gene expression. Additionally, metabolic disorders like diabetes not only frequently coexist with gliomas but also exacerbate tumor progression through mechanisms such as inflammation, oxidative stress, and epigenetic reprogramming. Tumors located near brain regions controlling heart function may also increase the risk of sudden death, particularly in diabetic patients. The review proposes a comprehensive framework to understand glioma development by linking metabolism, epigenetics, and overall health. This integrated perspective leads to novel personalized treatment approaches, targeting both the tumor and the patient’s broader metabolic health, with the potential to improve survival rates and quality of life for glioma patients.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is an independent risk factor for cardiovascular disease (CVD). While gut bacteria have been linked to CVD, the role of intestinal fungi in subclinical coronary atherosclerosis (SCA) remains unclear. In this study, we aimed to investigate the association between the gut mycobiome and SCA in MASLD.

A cross-sectional study was conducted among 103 MASLD patients without established CVD. Fibrosis and steatosis were assessed using magnetic resonance elastography (MRE) and proton density fat fraction, respectively. SCA was defined by coronary artery calcification (CAC). Fecal fungal composition was analyzed via internal transcribed spacer sequencing.

Mean age was 60.8 ± 11.2 years; 51.5% were men; 20.4% had cirrhosis. CAC correlated with MRE (r = 0.489, p < 0.001), interleukin-6 (r = 0.407, p < 0.001), and tumor necrosis factor-α (r = 0.254, p = 0.018), but not proton density fat fraction. Cirrhosis patients had higher CAC than F0–F3 (456.9 vs. 205.9, p = 0.033). Candida albicans (C. albicans) abundance was greater in cirrhosis and correlated with CAC (r = 0.403, p < 0.001) and MRE (r = 0.212, p = 0.032). In multivariate analysis, older age, diabetes, obesity, cirrhosis, and enriched C. albicans independently predicted CAC ≥ 100 AU in MASLD.

In MASLD, cirrhosis and C. albicans enrichment are independently associated with higher SCA burden, suggesting advanced liver disease and a potential fungal contribution to CVD pathogenesis.

Metabolic dysfunction-associated steatotic liver disease (MASLD) affects approximately 32% of the US adult population. The present study aimed to utilize the All of Us electronic health record-linked large cohort to assess seven metabolic risk factors (MRFs) simultaneously, the impact by ethnicity and age, and clinical presentations of MASLD.

This study included a MASLD group (n = 15,060) and a frequency-matched control group (n = 75,300). Multivariable analyses were performed to compare the frequencies of MRFs and clinical outcomes between the two groups. Type 1 diabetes was not included in the multivariable analysis. Subgroup analyses were conducted according to race and ethnicity, as well as age.

The overall frequency of MASLD was 6.0%. Compared with the control group, individuals with MASLD had significantly higher independent frequencies of obesity (66.1% vs. 41.3%), type 2 diabetes (39.5% vs. 16.9%), hypertension (64.3% vs. 38.6%), hyperlipidemia (59.8% vs. 37.3%), obstructive sleep apnea (28.9% vs. 13.4%), and hypothyroidism (21.2% vs. 13.4%). Obesity was identified as the strongest independent MRF among Asians, Whites, and Hispanics, particularly in individuals younger than 50 years, whereas hypertension was the strongest independent MRF in Blacks. MASLD was also associated with significantly higher frequencies of cardiac events, including coronary artery disease (17.1% vs. 9.4%) and myocardial infarction (7.1% vs. 4.2%); hepatic events, including cirrhosis (7.5% vs. 1.1%) and hepatocellular carcinoma (0.5% vs. 0.1%); and elevated liver enzymes, including alanine aminotransferase (27.7% vs. 10.1%), aspartate aminotransferase (18.0% vs. 6.4%), and alkaline phosphatase (19.8% vs. 13.1%), compared with the control group.

Our study demonstrated that obesity, hypertension, hyperlipidemia, type 2 diabetes, obstructive sleep apnea, and hypothyroidism were independent MRFs for MASLD overall, but the ranking of these MRFs by odds ratios could vary by ethnicity and age. MASLD presents with significantly higher rates of alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase elevation, as well as cardiac and hepatic events.
