Hepatocellular carcinoma (HCC) is one of the most fatal malignancies. Epigenetic mechanisms have revealed that noncoding RNAs, such as microRNAs (miRNAs) and circular RNAs (circRNAs), are involved in HCC progression. This study aimed to construct a circRNA-miRNA-mRNA network in HCC and validate one axis within the network.

HCC-related transcriptome data were obtained from the Gene Expression Omnibus, and HCC-related genes were sourced from GeneCards to identify differentially expressed circRNAs and miRNAs. The targeting relationships between circRNA-miRNA and miRNA-mRNA interactions were predicted. The involvement of the hsa_circ_0001726/miR-140-3p/KRAS axis in HCC was evaluated through cellular experiments and survival analyses.

We identified six differentially expressed circRNAs in HCC, which were linked to 13 miRNAs and 88 mRNAs. A network containing 34 circRNA-miRNA pairs and 194 miRNA-mRNA pairs was constructed. Cell proliferation and migration assays confirmed the role of hsa_circ_0001726 in promoting HCC progression, possibly through the miR-140-3p/KRAS axis. Survival analysis verified that hsa_circ_0001726 was a prognostic factor for overall survival in patients with HCC. The hsa_circ_0001726/miR-140-3p/KRAS axis also mediates lenvatinib resistance in HCC cells.

The HCC circRNA/miRNA/mRNA network provides new insights into the post-transcriptional regulatory mechanism of HCC. The hsa_circ_0001726/miR-140-3p/KRAS axis is involved in HCC progression and lenvatinib resistance.

The effect of tenofovir amibufenamide (TMF) on blood lipid profiles in patients with chronic hepatitis B (CHB) remains unclear. This study aimed to explore whether TMF affects blood lipids during 48 weeks in patients with CHB.

A total of 91 patients with CHB undergoing TMF treatment for 48 weeks were divided into two groups: Lipid Normal (n = 42) and Lipid Abnormal (n = 49), based on baseline blood lipid levels. Lipid indices, virological responses, and biochemical indicators were compared between the two groups. Clinical observations were further verified through in vitro experiments.

After an average follow-up of 373 ± 121 days, lipid indices in all 91 patients had not significantly changed compared with baseline (total cholesterol: 4.67 vs. 4.69 mmol/L, P = 0.2499; triglycerides: 1.08 vs. 1.04 mmol/L, P = 0.4457; high-density lipoprotein cholesterol: 1.25 vs. 1.25 mmol/L, P = 0.3063; low-density lipoprotein cholesterol: 3.03 vs. 3.02 mmol/L, P = 0.5765). Subgroup comparisons showed lipid indices remained stable. Among treatment-naïve patients (n = 82), complete viral suppression rates were 23.2%, 59.8%, 70.7%, and 86.6% at four, 12, 24, and 48 weeks, respectively. Cellular experiments revealed that TMF did not promote lipid metabolism in primary hepatocytes and AML12 cells.

Regardless of baseline blood lipid characteristics, 48 weeks of antiviral treatment with TMF in patients with CHB had no significant lipid-raising effect.

Bilirubin, the primary breakdown product of hemoproteins, particularly hemoglobin, plays a key role in the diagnosis, prognosis, and monitoring of liver diseases. In acute liver diseases, such as acute liver failure, drug-induced liver injury, and viral hepatitis, bilirubin serves as a biomarker reflecting the extent of hepatocyte loss and liver damage. Chronic liver diseases, including alcohol-related liver disease, chronic hepatitis C virus infection, metabolic dysfunction-associated fatty liver disease, and autoimmune liver diseases, are marked by persistent liver injury and inflammation. Bilirubin levels in chronic liver diseases provide insight into liver function, disease severity, and prognosis. As a versatile biomarker, bilirubin offers valuable information on the pathophysiology of liver diseases and aids in guiding clinical decision-making regarding the treatment of liver diseases and their complications. This review aimed to explore the multifunctional role of bilirubin in liver diseases by analyzing its biological functions beyond its role as a biomarker of liver damage.

Glutathione peroxidase 4 (GPX4) is a key factor in ferroptosis, which is involved in ischemia-reperfusion injury. However, little is known about its role in hepatic ischemia-reperfusion injury (HIRI). This study aimed to investigate the role of GPX4 methylation in ferroptosis during HIRI.

For the in vitro experiments, an oxygen and glucose deprivation cell model was established. For the in vivo experiments, an ischemia-reperfusion model was created by subjecting mice to simulated HIRI. Ferroptosis occurrence, GPX4 promoter methylation, and global methylation levels were then assessed.

Ferroptosis was observed in oxygen and glucose deprivation, characterized by a significant decrease in cellular viability (P < 0.05), an increase in lipid peroxidation (P < 0.01), iron overload (P < 0.05), and down-regulation of GPX4 (P < 0.05). This ferroptosis was exacerbated by GPX4 knockdown (P < 0.01) and mitigated by exogenous glutathione (P < 0.01). Similarly, ferroptosis was evident in mice subjected to HIRI, with a down-regulation of GPX4 mRNA and protein expression (all P < 0.01), and an upregulation of acyl-CoA synthetase long-chain family member 4 mRNA and protein (all P < 0.01), as well as prostaglandin-endoperoxide synthase 2 mRNA and protein expression (all P < 0.05). Methylation levels increased, evidenced by upregulation of DNA methylation transferase expression (P < 0.05) and down-regulation of Ten-eleven translocation family demethylases (P < 0.01), along with an upregulation of GPX4 promoter methylation.

Ferroptosis may be the primary mode of cell death in hepatocytes following ischemia-reperfusion injury. The methylation of the GPX4 promoter and elevated levels of global hepatic methylation are involved in the regulation of ferroptosis.

The brain, traditionally regarded as immune-privileged due to the blood-brain barrier, harbors a sophisticated immune system crucial for maintaining neural health and resilience against various challenges. Microglia, the resident immune cells of the central nervous system, actively monitor their environment, participating in immune surveillance, synaptic pruning, and neuroprotection. Astrocytes also play vital roles by regulating neurotransmitter levels, supporting metabolism, and maintaining the blood-brain barrier integrity. Recent research underscores the involvement of T cells and monocytes in modulating neuroinflammation and immune responses within the brain. Neurological disorders such as Alzheimer’s and Parkinson’s disease highlight the brain’s vulnerability to immune dysregulation. This review aimed to elucidate the role of neuroimmune cells in brain health and the progression of neurological diseases. It aimed to identify critical mechanisms to enhance therapeutic strategies and improve outcomes. Understanding these interactions is essential for developing targeted therapies to mitigate neuroinflammation and preserve cognitive functions. This review critically examines neuroinflammation related to aging and disease, with a focus on neuroimmune cells and their underlying mechanisms. It highlights how chronic inflammation, driven by activated microglia and astrocytes, exacerbates neuronal damage, synaptic dysfunction, and cognitive decline. The disruption of immune privilege in these conditions involves complex pathways that trigger inflammatory responses, impairing essential neural functions. Despite its immune-privileged status, the brain’s immune system, primarily involving microglia and astrocytes, is crucial for maintaining homeostasis and managing illness. Our review strongly suggests that neurological diseases, influenced by genetic, environmental, and aging factors, often involve heightened neuroinflammation. Targeted therapies are needed to address infections, chronic inflammation, and environmental impacts. Additionally, research into mental health disorders and advancements in imaging techniques are critical for understanding immune dysfunction and enhancing treatment strategies.

Helicobacter pylori (H. pylori) infection can cause multiple secondary digestive disorders. Some studies have found that polymorphisms in Toll-like receptor (TLR) genes, including TLR10 rs10004195, may be associated with increased susceptibility to H. pylori infection. Despite conflicting reports, we conducted a meta-analysis to clarify the relationship between these factors.

We conducted an exhaustive review, encompassing all relevant literature up to February 2024, using databases such as PubMed, Embase, Web of Science, and the China National Knowledge Infrastructure. We screened studies based on specific criteria and evaluated their quality using the Newcastle-Ottawa scale. Heterogeneity testing and meta-analysis were performed using Stata 17.0 software, and SPSSAU was used for publication bias evaluation and sensitivity analysis.

Eight of the 487 identified studies met the inclusion criteria, comprising 3,004 and 2,140 individuals in the H. pylori-positive and negative control groups, respectively. Our results demonstrated that individuals carrying the AA genotype at the TLR10 rs10004195 locus had a significantly increased likelihood of H. pylori infection when analyzed using the recessive genetic model (OR: 1.64, CI: 1.04–2.58, p = 0.034). No statistically significant associations were found in the other four genetic models.

Our findings suggest that carrying the TLR10 rs10004195 AA genotype is associated with a significantly elevated risk of H. pylori infection. This information could be used to assess future risk of H. pylori infection in healthy individuals and provide personalized health guidance based on individual genetic polymorphisms.

Data regarding risk factors and long-term outcomes of U.S. patients with biopsy-proven metabolic dysfunction-associated steatotic liver disease (MASLD) are limited. This study aimed to investigate the role of clinical and histologic risk factors on long-term outcomes in patients with MASLD.

A retrospective cohort study of 451 adults with biopsy-proven MASLD was conducted at a U.S. academic hospital from 2012 to 2020. An experienced pathologist evaluated the index liver biopsy. Patients with a prior liver transplant or alternative etiologies of chronic liver disease were excluded. The duration of the risk exposure was determined from the date of the index liver biopsy to an outcome event or the last follow-up examination. Outcome events of interest included incident liver-related events, liver decompensation, and all-cause mortality.

In the final cohort of 406 patients followed for a median of 3.7 years (interquartile range: 4.8 years), 35 patients died, 41 developed hepatic decompensation, and 70 experienced a liver-related event. Among histologic risk factors, stage 3 (adjusted Hazard ratio (aHR) 2.68, 95% confidence interval (CI) 1.18–6.11) and stage 4 (aHR 6.96, 95% CI 3.55–13.64) fibrosis were associated with incident liver-related events compared to stage 0–1 fibrosis. Stage 4 (aHR 8.46, 95% CI 3.26–21.99) fibrosis alone was associated with incident liver decompensation events compared to stage 0–1 fibrosis. Among clinical risk factors, hypertension (aHR 2.58, 95% CI 1.05–6.34) was associated with incident liver decompensation.

In a U.S. single-center cohort of patients with biopsy-proven MASLD, advanced fibrosis was the primary risk factor for incident liver decompensation and liver-related events.

Circulating tumor cells (CTCs), originating from primary neoplastic tissues, infiltrate blood vessels, migrate through the bloodstream, and establish secondary tumor foci. The detection of CTCs holds significant promise for early-stage identification, diagnostic precision, therapeutic monitoring, and prognostic evaluation. It offers a non-invasive approach and has broad clinical relevance in cancer management. This comprehensive review primarily focused on CTCs as biomarkers in the diagnostic, therapeutic, and prognostic surveillance of hepatocellular carcinoma, compared their correlation with key clinical parameters and the identification of gene characteristics. It also highlighted current methodologies in CTC detection. Despite approval by the U.S. Food and Drug Administration for select malignancies, the comprehensive integration of CTCs into routine clinical practice requires procedural standardization and a deeper understanding of the underlying molecular intricacies. The challenges in CTC detection, including limited quantity, technical impediments, and cellular heterogeneity, call for concerted and further investigational efforts to advance precision in cancer diagnostics and prognostication, thus realizing the objectives of precise and personalized medicine.

Early detection of hepatocellular carcinoma (HCC) is crucial for improving survival in patients with chronic hepatitis. The GALAD algorithm combines gender (biological sex), age, α-fetoprotein (AFP), Lens culinaris agglutinin-reactive fraction of AFP (AFP-L3), and protein induced by vitamin K absence or antagonist-II (PIVKA-II) for HCC detection. Similarly, the GAAD algorithm incorporates gender (biological sex), age, AFP, and PIVKA-II. This study aimed to assess the clinical utility of AFP-L3 in the GALAD algorithm and its potential synergies with ultrasound. We compared the clinical performance of GALAD with GAAD; AFP; AFP-L3; and PIVKA-II, with or without ultrasound, in Taiwanese adults.

A total of 439 serum samples were analyzed using a Cobas® e 601 analyzer (healthy controls, n = 200; chronic liver disease controls, n = 177; HCC cases, n = 62). Performance was assessed through receiver operating characteristic curve analyses to calculate the area under the curve.

The area under the curve for differentiating early-stage HCC from patients with chronic liver disease was optimal for PIVKA-II (84.9%), GAAD (79.8%), and GALAD (79.4%), with slightly improved performance for detecting all-stage HCC. Clinical performance was unaffected by disease stage or etiology. Sensitivity for early-stage HCC was highest for GAAD (57.6%) and GALAD (57.6%). Sensitivity for each strategy was further enhanced when combined with ultrasound, regardless of disease stage or etiology (P < 0.01).

These findings indicate that the role of AFP-L3 in the GALAD algorithm is minimal, supporting the use of GAAD for HCC detection. A combination of GAAD, GALAD, or PIVKA-II with ultrasound may improve diagnostic efficiency compared with recommended strategies.

This review discussed experimental mouse models used in the pre-clinical study of liver fibrosis regression, a pivotal process in preventing the progression of metabolic dysfunction-associated steatohepatitis to irreversible liver cirrhosis. These models provide a valuable resource for understanding the cellular and molecular processes underlying fibrosis regression in different contexts. The primary focus of this review is on the most commonly used models with diet- or hepatotoxin-induced fibrosis, but it also touches upon genetic models and mouse models with biliary atresia or parasite-induced fibrosis. In addition to emphasizing in vivo models, we briefly summarized current in vitro approaches designed for studying fibrosis regression and provided an outlook on evolving methodologies that aim to refine and reduce the number of experimental animals needed for these studies. Together, these models contribute significantly to unraveling the underlying mechanisms of liver fibrosis regression and offer insights into potential therapeutic interventions. By presenting a comprehensive overview of these models and highlighting their respective advantages and limitations, this review serves as a roadmap for future research.

Early determination of prognosis in patients with acute-on-chronic liver failure (ACLF) is crucial for optimizing treatment options and liver allocation. This study aimed to identify risk factors associated with ACLF and to develop new prognostic models that accurately predict patient outcomes.

We retrospectively selected 1,952 hospitalized patients diagnosed with ACLF between January 2010 and June 2018. This cohort was used to develop new prognostic scores, which were subsequently validated in external groups.

The study included 1,386 ACLF patients and identified six independent predictors of 28-day mortality through multivariate analysis (all p < 0.05). The new score, based on a multivariate regression model, demonstrated superior predictive accuracy for both 28-day and 90-day mortalities, with Areas under the ROC curves of 0.863 and 0.853, respectively (all p < 0.05). This score can be used to stratify the risk of mortality among ACLF patients with ACLF, showing a significant difference in survival between patients categorized by the cut-off value (log-rank (Mantel–Cox) χ2 = 487.574 and 606.441, p = 0.000). Additionally, the new model exhibited good robustness in two external cohorts.

This study presents a refined prognostic model, the Model for end-stage liver disease-complication score, which accurately predicts short-term mortality in ACLF patients. This model offers a new perspective and tool for improved clinical decision-making and short-term prognostic assessment in ACLF patients.

A growing body of literature has demonstrated improved quality of life in cancer patients who utilize web-based patient portals; however, no studies have investigated their impact on objective clinical measures. The study aimed to evaluate the impact of patient portal utilization on clinical outcomes in cancer care. Patient portal platforms provide patients with direct access to their providers through messaging, medication requests, and other tools. There is a knowledge gap in the literature regarding whether electronic patient portals enhance outcomes in cancer care.

This study is a retrospective analysis of 791 patients with multiple myeloma within the Scripps Health system. The effect of MyScripps electronic patient portal use on unplanned hospital visits and mortality was assessed. Outcomes were also evaluated in relation to the age-adjusted Charlson comorbidity index and chemotherapy use.

Results showed that older, male, Hispanic, and Spanish-speaking patients had lower portal utilization. Those with inactive portal status had higher rates of unplanned hospital visits and mortality. Inactive portal status was an independent predictor of unplanned hospital visits in two multivariable logistic regression analyses. A logistic regression model investigating the interaction between patient portal use and age-adjusted Charlson comorbidity index revealed that active portal status remained a predictor of unplanned hospital visits.

This study highlights the potential to improve clinical outcomes among patients with multiple myeloma, particularly in vulnerable communities, by increasing access to electronic patient portals.

The prevalence and fatality rates of cutaneous malignant melanoma (CMM) have been rising, particularly among the elderly. This study analyzes CMM incidence trends in the United States elderly population from 1987 to 2016 to inform prevention and management strategies.

Using incidence data from the Surveillance, Epidemiology, and End Results database spanning 1989 to 2008, we calculated the age-adjusted standardized population incidence rates for CMM in elderly individuals. The Joinpoint software was employed to estimate annual percent change and analyze trends in CMM incidence among elderly individuals from 1987 to 2016.

The study included 56,997 elderly CMM patients from eight Surveillance, Epidemiology, and End Results registries, of whom 36,726 were male (64.4%). The age-adjusted CMM incidence rate from 2012 to 2016 was 0.99 per 1,000, a 2.8-fold increase from 1987–1991 (95% confidence interval: 2.7–2.9). Incidence rates increased with age and birth cohort, peaking at 1.53 per 1,000 males and 0.59 per 1,000 females aged 85+ during 2012–2016. Birth cohort effects also showed a continuous increase.

This study reveals a substantial increase in CMM incidence rates among the elderly from 1987 to 2016, particularly between 2012 and 2016. Incidence rates escalated with age and birth cohort, with the highest rates observed in individuals aged 85 and older.

Cancer is thought to be the second most prevalent and leading cause of mortality worldwide, affecting both men and women among other chronic diseases. While there are several treatment options available, significant strains, side effects, and resistance have led researchers to focus on finding novel alternative medications for cancer treatment. Antioxidants and the immunomodulatory activities of medicinal plants are studied and considered to have anti-cancer effects. Medicinal plants contain diverse phytoconstituents as natural drugs, which possess numerous medicinal properties used for treating and preventing various illnesses. These phytoconstituents work through several mechanisms to target and kill cancer cells. Anticancer mechanisms include suppression and arrest of the G0/G1 phase, acting as anti-mitotic and anti-microtubule agents, enhancing the activity of macrophages, inhibiting cancer cells through various signaling cascades, anti-angiogenesis, and cytotoxicity. Investigating botanical sources and their metabolites can uncover new chemical entities for cancer treatment at the molecular target level and provide future interventions in cancer therapy. This article summarizes a few medicinal plants and their mechanisms of action for their anticancer potential. Furthermore, we discuss the future prospects and limitations of using medicinal plants in cancer treatment.

Gastrointestinal dysmotility commonly follows thermal injuries, such as burns. This study aimed to investigate the effects and mechanisms of electroacupuncture (EA) on burn-induced gastric dysmotility in rats.

Sprague-Dawley rats were divided into sham and thermal injury groups subjected to a 60% scald burn. Antagonists, including β-blockade (propranolol), α-blockade (phentolamine), or a selective cyclooxygenase (COX)-2 inhibitor (nimsulide), were administered to verify the pathways involved. Six hours after the burn, the animals were evaluated for gastric emptying and heart rate variability. Blood and gastric tissues were collected for assays of cytokines, hormones, and COX-2 levels. EA was performed at bilateral ST36 (Zusanli) acupoints for 45 m.

Burn injury delayed gastric emptying by 61% (P < 0.01), which was normalized by nimsulide or propranolol but not by phentolamine. EA improved gastric emptying by 87% (P = 0.03) in burned rats. Heart rate variability and plasma hormone (noradrenaline and pancreatic polypeptide) analyses indicated sympathetic hyperactivity in burned rats; EA improved burn-induced sympathovagal imbalance by enhancing vagal activity. Protein and mRNA expressions of COX-2 in the gastric fundus and antrum increased with burn but were normalized by propranolol. EA reduced the burn-induced increase in COX-2 expression in the gastric fundus but not in the antrum. EA also decreased burn-induced elevations in plasma interleukin (IL)-6 and IL-10. Negative correlations were found between gastric emptying and plasma IL-6 levels, as well as between gastric emptying and COX-2 mRNA levels.

These findings suggest that burn-induced gastric dysmotility is mediated via autonomic-COX-2 pathways. EA at acupoint ST36 improves burn-induced delays in gastric emptying by down-regulating COX-2 and pro-inflammatory cytokines through the autonomic nervous pathway.

The incidence of cardia gastric cancer (CGC) is rising worldwide, particularly in East Asia. There has been a debate over whether Helicobacter pylori (H. pylori) constitutes a risk factor for CGC. This study aimed to evaluate the relative risk of H. pylori infection and CGC in Asian countries.

Relevant studies examining H. pylori and CGC were searched in PubMed, Embase, and Web of Science from their inception to June 30, 2024. Either a random-effect model or a fixed-effect model was used to calculate pooled odds ratios (ORs) with 95% confidence intervals (CIs). Sensitivity analyses and assessments of publication bias were performed. The stability of results was evaluated in cases where publication bias was detected.

A total of 24 studies were included in the meta-analysis. A significant association between H. pylori and CGC was observed (OR = 2.20, 95% CI 1.73–2.80). In a subgroup analysis of different countries, a significant association was observed in East Asian countries, including China (OR = 2.12, 95% CI 1.63–2.77), Japan (OR = 2.21, 95% CI 1.16–4.20), and Korea (OR = 2.36, 95% CI 1.58–3.54), but not in Iran (OR = 1.48, 95% CI 0.77–2.84). The pooled OR from five prospective cohort studies revealed a strong association between H. pylori and CGC (OR = 2.32, 95% CI 1.47–3.66).

East Asia bears a significant burden of H. pylori-related CGC. A clear association between H. pylori infection and CGC was observed in this region.

Tumor molecular analysis using next-generation sequencing (NGS) is the standard of care for guiding lung cancer treatment. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive technique used to sample mediastinal lymph nodes for diagnosing and staging lung cancer. This study aimed to determine if EBUS-TBNA provided adequate tissue samples for NGS.

We evaluated EBUS-TBNA samples from adult advanced non-small cell lung cancer patients who had both EBUS-TBNA and liquid biopsy samples analyzed by NGS between July 1, 2015 and June 30, 2021. Additionally, we compared the results with those from liquid biopsies performed on these patients.

Among the 44 evaluated patients, 43% were male, with a median age of 66 years at diagnosis. Seventy-five percent were smokers, 79.5% were White, 6.8% were Black, and 9.1% were Asian. EBUS-TBNA samples were sufficient for NGS in 95.5% of cases. The median turnaround time for EBUS-TBNA NGS was 38.5 days compared with eight days for NGS in liquid biopsies. Actionable genetic aberrations were detected in 71% of patients.

Our findings demonstrated that EBUS-TBNA provided sufficient tissue for identifying actionable genetic aberrations in patients with advanced non-small cell lung cancer.

Mesothelioma is an aggressive tumor with a poor prognosis. Histological diagnosis of mesothelioma using limited tissue samples can be challenging. Carbonic anhydrase IX (CAIX) is a transmembrane protein that is overexpressed in a variety of solid tumors. This study aimed to investigate the clinical utility of CAIX expression in the differential diagnosis of pleural mesothelioma from non-small cell lung carcinoma (NSCLC).

Unstained tissue microarray slides composed of 56 cases of pleural mesothelioma and 82 cases of NSCLC were subjected to immunohistochemical staining using a mouse anti-human antibody against CAIX.

Of the 38 epithelioid mesothelioma cases, 34 (89%) displayed diffuse and strong cytoplasmic membrane reactivity, while the remaining four cases (11%) showed weak to moderate staining in tumor cells. Five out of sixteen (5/16) sarcomatoid mesothelioma cases were negative. Among the non-small cell lung carcinoma cases, 76% (32/42) of adenocarcinomas and 57% (21/37) of squamous cell carcinomas were completely negative, whereas the remaining cases showed focal weak expression of CAIX.

Our study demonstrates that CAIX expression has a high sensitivity (100%) in detecting pleural epithelioid mesothelioma, which is comparable to or better than currently used mesothelial markers. The specificity of CAIX is within a comparable range to that of commonly used mesothelial markers for differentiating epithelioid mesothelioma from NSCLC. Therefore, we recommend that CAIX immunohistochemistry staining be considered as an additional tool for the differential diagnosis of mesothelioma, particularly pleural epithelioid mesothelioma, from its common mimicker, NSCLC.

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive disease with difficulties in early diagnosis, poor prognosis, and limited effective therapies. Early detection and effective treatment offer the optimal chance to improve survival rates. Various studies have shown that gut microbiota dysbiosis is closely related to PDAC, with potential mechanism involving immune regulation, metabolic process impact, and reshaping the tumor microenvironment. A comprehensive understanding of the microbiota in PDAC might lead to the establishment of screening or early-stage diagnosis methods, implementation of cancer bacteriotherapy such as fecal microbiota transplantation, creating new opportunities and fostering hope for desperate PDAC patients.
