Obstructive sleep apnea (OSA) is a prevalent sleep disorder characterized by intermittent hypoxia and sleep fragmentation, which may contribute to lung cancer development and progression. This review synthesizes epidemiological evidence on the association between OSA and lung cancer incidence and mortality, highlighting inconsistencies due to study design, population differences, and confounding factors such as smoking and obesity. While some studies report an increased lung cancer risk, particularly with severe nocturnal hypoxemia, others suggest no significant association or a potential protective effect. Pathophysiologically, OSA promotes oncogenesis through hypoxia-inducible factor activation, tumor immune microenvironment remodeling, exosome-mediated signaling, nuclear factor κB pathway activation, and enhanced cancer stem cell properties. Continuous positive airway pressure therapy may mitigate these effects, with evidence suggesting reduced lung cancer incidence and improved prognosis in adherent patients. This review underscores the need for standardized studies using objective diagnostics and robust confounder adjustment to clarify the OSA–lung cancer link and optimize clinical management.

Metabolic dysfunction-associated steatotic liver disease (MASLD) and sarcopenia frequently coexist, yet their causal relationship and underlying mechanisms remain poorly defined. This study aimed to investigate whether a bidirectional causal link exists between MASLD and sarcopenia and to identify the molecular mediators involved in liver-muscle crosstalk.

We applied Mendelian randomization to test the causal effect of sarcopenia-related traits on MASLD risk. To capture distinct clinical features, we established complementary mouse models, including diet-induced and genetic (ob/ob) MASLD models, a stelic animal model, and a drug-induced muscle atrophy model. Multi-tissue transcriptomic profiling was performed on liver and muscle to uncover altered pathways.

Complementing prior genetic evidence establishing MASLD as a causal factor for sarcopenia, our Mendelian randomization analysis revealed that diminished muscle mass and muscle function contribute to an elevated risk of MASLD. In mice with MASLD, we observed loss of muscle mass, reduced strength, and ectopic lipid deposition in skeletal muscle. Conversely, muscle atrophy exacerbated hepatic steatosis, inflammation, and fibrosis in MASLD mice. Transcriptional profiling revealed that sarcopenia impairs hepatic metabolic homeostasis by enhancing fatty acid uptake and impairing oxidative phosphorylation, while MASLD, in turn, promotes muscle dysfunction by exacerbating inflammatory responses and metabolic dysfunction. We further identified C-C motif chemokine ligand 2 as a key myokine that drives MASLD, and adrenomedullin as a key hepatokine that triggers sarcopenia.

Our findings suggest a potential bidirectional causal relationship between MASLD and sarcopenia, which may be partially mediated by C-C motif chemokine ligand 2 and adrenomedullin.

Hepatocellular carcinoma (HCC) remains one of the most fatal cancers, primarily due to late diagnosis and the lack of effective early biomarkers. Recent advances in multi-omics and liquid biopsy technologies hold promise for improving early detection, prognostication, and monitoring of HCC. Understanding the immune landscape of HCC through genetic and epigenetic signatures is essential for identifying therapeutic targets and improving immunotherapy outcomes. This review aims to present current findings on immune-related biomarkers, multi-omics strategies, and biomarker validation in HCC. It also aims to evaluate the role of liquid biopsy and gene signatures in predicting treatment responses, with a specific focus on their applications in immunotherapy. The goal is to provide a comprehensive framework for integrating these emerging tools into clinical practice. The integration of multi-omics approaches has led to the identification of robust gene signatures that predict HCC prognosis and response to immune checkpoint inhibitors. Liquid biopsy technologies, including circulating tumor DNA, provide non-invasive alternatives for monitoring tumor evolution and therapeutic responses. Despite promising results, challenges remain in clinical validation, particularly in cross-platform reproducibility and the interpretation of complex multi-omics data. While genetic biomarkers are rapidly advancing, their clinical application in personalized medicine remains hindered by technical and ethical challenges, such as data privacy, informed consent, and method standardization. The integration of multi-omics data and liquid biopsies offers a promising path toward real-time, personalized treatment and the development of universal prognostic signatures for HCC. However, successful clinical adoption depends on cross-disciplinary collaboration to standardize data protocols and overcome challenges regarding accuracy, reproducibility, and patient privacy.

Helicobacter pylori infection represents a significant modifiable risk factor in the pathogenesis of gastric cancer. Nevertheless, conventional antibiotic treatments have increasingly proven inadequate due to challenges such as antibiotic resistance, microbial dysbiosis, and mucosal damage. In response to these issues, this review introduces an innovative intervention strategy based on the “nanotechnology-based 3R” approach (Remove H. pylori, Remodel the microenvironment, Repair the gastrointestinal tract), which aims to offer a comprehensive solution for managing H. pylori infection. This strategy comprises three principal components. Firstly, the utilization of pH/light/magnetic multi-responsive nanomaterials facilitates the precise eradication of the pathogen and its biofilm. Secondly, to address bacterial immune evasion, these nanomaterials are engineered to target and neutralize virulence factors such as VacA, thereby contributing to the reversal of the local immunosuppressive environment. Thirdly, the utilization of nanomaterials presents a promising approach for the concurrent repair of the mucosal barrier and the maintenance of intestinal microbiome homeostasis. Finally, this paper provides a comprehensive analysis of the specific mechanisms employed by typical nanomaterials, including metal-organic frameworks, charge-reversal nanoparticles, nanozymes, and antimicrobial peptide crystals. These mechanisms involve targeted microbial eradication, activation of autophagy, and the upregulation of tight junction proteins. Furthermore, the study delves into the critical roles played by multimodal external field stimulation and material–host interaction network analysis, which are essential for future clinical translation. Ultimately, this review suggests a potential roadmap for system-precision intervention that transcends the conventional “sterilization first” paradigm. Nonetheless, the current evidence regarding the efficacy and safety of this approach is predominantly derived from cell and mouse models. Therefore, its clinical applicability requires validation through studies involving large animal models and prospective clinical trials.

Dysphagia, a severe comorbidity of many neurological diseases, often lacks targeted therapies. Electrical stimulation of cranial nerves represents a novel therapeutic class. This critical review assessed the clinical effectiveness and safety of various approaches for electrical stimulation of the cranial nerves for treating dysphagia, categorized as implantable (directly targeting the nerve), minimally invasive (pharyngeal electrical stimulation), and non-invasive (transcutaneous). A critical literature review was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The PubMed database was comprehensively searched, and studies were rigorously assessed for inclusion and exclusion criteria. The Newcastle–Ottawa Scale was used to assess the risk of bias. The analysis included 15 clinical studies: four assessing vagus nerve stimulation (including implantable and transcutaneous approaches) and eleven assessing pharyngeal electrical stimulation. Most evaluated studies, particularly for pharyngeal electrical stimulation and transcutaneous vagus nerve stimulation, demonstrated significant beneficial effects on validated dysphagia outcome measures. Importantly, no long-term severe adverse effects were reported across the evaluated stimulation approaches. Cumulative evidence indicates that vagus nerve stimulation and pharyngeal electrical stimulation approaches can effectively alleviate dysphagia symptoms. The different stimulation approaches appear to be complementary, with distinct profiles rendering them suitable for different therapeutic contexts (e.g., short-term hospital-based vs. long-term at-home treatment). Consequently, they represent distinct and valuable options for individualized dysphagia therapy.

Micro- and nanoplastics (MNPs) are pervasive environmental contaminants with growing recognition as potential contributors to human disease. Widespread human exposure occurs primarily through ingestion of contaminated food and water, and MNPs have been detected in multiple human tissues, including the gastrointestinal tract. Experimental evidence provides a plausible biological basis for disease associations, including impairment of intestinal barrier integrity, activation of mucosal immune pathways, and alteration of gut microbial communities caused by MNP exposure. Although human data remain limited, early studies demonstrate MNP detection in stool and suggest potential correlations with inflammatory biomarkers such as fecal calprotectin. These findings, together with mechanistic data from in vitro and animal models, raise concern that MNP exposure represents a paradigm shift in the pathogenesis or modulation of inflammatory bowel disease (IBD); however, methodological variability, small sample sizes, and contamination challenges currently limit definitive conclusions. The aim of this review is to evaluate the current understanding of MNP exposure and its impact on intestinal health, particularly in relation to IBD. We synthesize mechanistic and early clinical evidence linking MNPs to IBD and highlight critical research gaps. Future standardized exposure assessment, mechanistic validation in human systems, and longitudinal studies are essential to clarify causal relationships. Given the modifiable nature of environmental plastic exposure, advancing this field may offer new opportunities for IBD prevention and intervention.

Medulloblastoma (MB) is a malignant neoplasm that is relatively common in children but rare in young adults, accounting for less than 1% of all intracranial tumors. This study reports a rare case of MB metastasis to the right temporoparietal region in a 42-year-old woman, presenting with focal neurological symptoms such as weakness in the left arm and leg, speech disturbances, and impaired coordination. The patient had a history of cerebellar MB and underwent surgical resection, radiation therapy, and chemotherapy. Despite treatment, metastasis occurred, highlighting the diagnostic and therapeutic challenges in adult MB cases. The article also reviews the literature on MB in young adults, emphasizing the importance of dynamic neuroclinical monitoring and timely instrumental diagnosis for early detection and management of MB metastases.

A long-term high-fat diet (HFD) exerts lipotoxic effects on multiple organs, particularly the liver, leading to metabolic diseases. This study aimed to delineate the dynamic effects of HFD on lipid metabolism, elucidate the mechanisms underlying hepatic lipotoxicity, and investigate the protective effects of Ganoderma lucidum against lipotoxicity both in vitro and in vivo.

C57BL/6 mice were fed either a 45% or 60% HFD, followed by measurements of body composition, serum lipid profile, and liver pathology at four, eight, twelve, and sixteen weeks. Inflammatory responses, the unfolded protein response (UPR), and endoplasmic reticulum (ER)-phagy were examined in the livers of mice at 16 weeks. Male C57BL/6 mice were randomly assigned to four groups (n = 12 per group): normal diet, 45% HFD, and two HFD + Ganoderma lucidum water extract (GLE) groups (1 g/kg/d and 2 g/kg/d of crude drug, orally administered by gavage for eight weeks following a four-week HFD induction).

Body weight, body fat, serum lipids, and hepatic steatosis increased progressively, accompanied by impaired glucose tolerance and liver injury, as indicated by elevated serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels. HFD also induced activation of the STING and NF-κB signaling pathways, as well as the PERK and IRE1 branches of the UPR. Similarly, ER-phagy selective receptors, particularly FAM134B, which is primarily expressed in hepatocytes as shown by single-cell sequencing, were upregulated after 16 weeks of HFD feeding. Furthermore, GLE mitigated palmitic acid-induced lipotoxicity in primary hepatocytes, as evidenced by improved cell viability, reduced ALT, AST, and lactate dehydrogenase levels in the culture supernatant, and decreased transferase dUTP nick-end labeling-positive cell counts. In 45% HFD-fed mice, GLE reduced serum total cholesterol, low-density lipoprotein, and hepatic triglyceride levels.

HFD-induced lipotoxicity causes hepatic tissue injury and inflammatory responses, which may be alleviated by coordinated regulation of compensatory UPR and ER-phagy. Ganoderma lucidum shows promise as a dietary supplement for managing metabolic disorders.

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.

Early risk stratification of severe acute liver injury (SLI) that may progress to acute liver failure (ALF), is vital for timely intervention, but no universal prognostic assessment tool covers both conditions. This study aimed to develop a simplified prognostic model for early risk assessment in SLI/ALF patients.

A retrospective cohort study consecutively enrolled SLI patients (including those progressing to ALF) from July 1, 2020 to May 31, 2025. Baseline clinical and laboratory data on admission were collected, with 90-day transplant-free survival as the primary outcome. Independent prognostic factors were screened via Cox regression to build a simplified scoring model, whose performance was compared with the Model for End-Stage Liver Disease (MELD), King’s College Criteria (KCC), and the Acute Liver Failure Study Group Prognostic Index (ALFSG-PI).

Of 302 patients, 190 (62.9%) achieved 90-day transplant-free survival. Multivariate Cox regression identified international normalized ratio (hazard ratio [HR]: 1.118, 95% confidence interval [CI]: 1.050–1.191), platelet count (HR: 0.995, 95% CI: 0.993–0.998), and hepatic encephalopathy grade ≥ 2 (HR: 5.187, 95% CI: 3.403–7.907) as independent predictors, forming the HIP (derived from the above-mentioned three predictors) model. It showed good discrimination (area under the receiver operating characteristic curve [AUC]: 0.82), outperforming MELD (AUC: 0.76, P = 0.019) and KCC (AUC: 0.72, P = 0.002), and performing comparably to ALFSG-PI (AUC: 0.80, P = 0.429). The model also performed robustly in ALF subgroups defined by the American College of Gastroenterology and the 2024 Chinese Medical Association guidelines (AUCs: 0.80 and 0.76, respectively) and achieved an AUC of 0.85 in the validation set.

The HIP model is a simple and effective tool for prognostic risk stratification in SLI/ALF patients, suitable for emergency and primary care to facilitate timely intervention.
