Background/Objectives: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a major cause of chronic liver disease and is closely linked to obesity and metabolic syndrome, necessitating efficient, non-invasive diagnostic tools. Methods: This monocentric cross-sectional study included 178 patients (69.1% with MASLD, 30.9% normal subjects; 55% males; mean age 52.79 ± 12.56 years) who underwent anthropometric and biochemical assessments to determine the visceral adiposity index (VAI), triglyceride–glucose index (TyG), and lipid accumulation product (LAP), along with abdominal ultrasound and vibration-controlled transient elastography (VCTE) with controlled attenuation parameter (CAP). Results: Patients were categorized based on steatosis severity: S0–S1 (n = 64) and S2–S3 (n = 114). The TyG, VAI, and LAP values were significantly higher in S2–S3 cases (p < 0.0001) and showed moderate-to-strong correlations with both steatosis and fibrosis. Predictive models yielded AUROCs of 0.80 (TyG), 0.83 (VAI), and 0.79 (LAP) for diagnosing S2–S3 steatosis. The NAFLD fibrosis score (NFS) and FIB-4 classified fibrosis severity, but 36.8% of cases remained unclassified. Applying the TyG and VAI thresholds reduced this rate to 26.3%. Conclusions: These findings support the TyG, VAI, and LAP as valuable non-invasive biomarkers for MASLD assessment, enhancing the classification accuracy when conventional fibrosis scores are inconclusive.

Background and Objectives: Gastric cancer (GC) remains a leading cause of cancer mortality worldwide, and the COVID-19 pandemic posed new barriers in diagnosis and management. This study aimed to assess whether pandemic-related healthcare disruptions resulted in more advanced GC stages at presentation. We additionally examined the role of Helicobacter pylori (H. pylori) across non-cardia GC (NCGC) versus cardia GC (CGC) and evaluated the risk factors of upper gastrointestinal (GI) bleeding. Methods: A retrospective cohort of 121 adult patients with GC was enrolled from a tertiary Gastroenterology Unit in Western Romania, spanning pre-pandemic (March 2018–February 2020), pandemic (March 2020–February 2022), and post-pandemic (March 2022–February 2024) periods. Demographic profiles, TNM staging, histopathology, H. pylori status, and clinical outcomes—including GI bleeding—were extracted from medical records. Results: An increase in advanced GC (Stage III–IVB) was noted in the post-pandemic period (69.4% vs. 53.3% pre-pandemic; p = 0.021). H. pylori positivity remained higher in NCGC (70.6%) compared to CGC (44.6%; overall p = 0.041); however, CGC cases showed a rise in H. pylori prevalence post-pandemic (36.4% to 55.6%). One-year mortality was driven by an advanced stage (hazard ratio [HR] = 2.74, p = 0.002), diagnosis during the COVID-19 pandemic (HR = 1.66, p = 0.010), and age ≥70 years (HR = 1.88, p = 0.043). Conclusions: Our findings demonstrate that delayed diagnostic endoscopy correlated with a higher proportion of advanced GC in the post-pandemic phase. H. pylori was strongly linked to NCGC, though CGC showed an increasing trend in H. pylori prevalence. Patients on antithrombotic agents faced increased GI bleeding risks.

Background: Acute pancreatitis is a common condition with a variable prognosis. While the overall mortality rate of acute pancreatitis is relatively low, ranging between 3 and 5% in most cases, severe forms can result in significantly higher morbidity and mortality. Therefore, early risk assessment is crucial for optimizing management and treatment. The aim of the present study wasto compare simple prognostic markers and identify the best predictors of severity in patients with acute pancreatitis. Material and Methods: A retrospective analysis was carried outon 108 patients admitted in our center during one year with acute biliary pancreatitis. Acute pancreatitis severity was stratified based on the revised Atlanta criteria. Results: 108 subjects (mean age of 60.1 ± 18.6, 65.7% females) diagnosed with acute biliary pancreatitis were included. Based on the Atlanta criteria, 59.3% (64/108) of the subjects were classified as having mild acute biliary pancreatitis, 35.2% (38/108) as having a moderate–severe pancreatitis, and 5.5% (6/108) were classified as having severe acute pancreatitis. In univariate analysis, the following parameterswere associatedwith at least a moderate–severe form of acute pancreatitis: Balthazar score, fasting blood glucose (mg/dL), modified CTSI score, CRP values at 48 h, BISAP score at admission, CTSI score, Ranson score, duration of hospitalization (days), and the presence of leukocytosis (×1000/µL) (all p < 0.05).BISAP score at admission (AUC-0.91), CRP levels at 48 h (AUC-0.92), mCTSI (AUC-0.94), and CTSI score (AUC-0.93) had the highest area under the curve (AUC) for predicting the severity of acute pancreatitis. In multivariate analysis, the model including the following independent parameters was predictive for the severity of acute pancreatitis: CTSI score (p < 0.0001), BISAP score (p = 0.0082), and CRP levels at 48 h (p = 0.0091), respectively. The model showed a slightly higher AUC compared to the independent predictors (AUC-0.96). Conclusions: The use of a multiparametric prediction model can increase the accuracy of predicting severity in patients with acute biliary pancreatitis.

Background and Objectives: Helicobacter pylori (H. pylori) infection remains one of the most common chronic bacterial infections worldwide and is associated with a wide range of gastrointestinal disorders, including gastritis, peptic ulcer disease, and gastric cancer. Increasing rates of antibiotic resistance, particularly to clarithromycin and fluoroquinolones, represent a major therapeutic challenge. The objective of this study was to determine the prevalence of resistance-associated mutations in H. pylori-positive gastric biopsy samples from western Romania. Materials and Methods: We conducted a prospective study from January to December 2024, enrolling 138 patients undergoing gastroscopy. Biopsies were collected from the gastric antrum, and H. pylori infection was confirmed using the rapid urease test (RUT). Positive samples were further analyzed with the GenoType HelicoDR assay to detect mutations in the 23S rRNA gene (clarithromycin resistance) and gyrA gene (fluoroquinolone resistance). Clinical, demographic, and endoscopic data were also collected. Results:H. pylori infection was confirmed in 41.3% of the patients (57), of whom 63.2% (36) were treatment-naïve and 36.8% (21) had prior eradication therapy. Among treatment-naïve patients, clarithromycin resistance was identified in 19.4%, whereas previously treated patients showed a markedly higher resistance rate of 47.6% (p = 0.018). All clarithromycin-resistant cases carried the A2147G (23S MUT3) mutation. Fluoroquinolone resistance was present in 13.9% of naïve patients and increased to 23.8% in those with prior eradication therapy, with resistance linked to gyrA mutations at codons 87 (N87K) and 91 (D91 variants). Combined resistance to both antibiotics was observed only in a subset of previously treated patients. Conclusions: Primary resistance to clarithromycin in western Romania exceeds the 15% threshold defined by international guidelines, making clarithromycin-based triple therapy unsuitable as an empirical first-line option. The findings support the use of bismuth quadruple therapy as the preferred empirical regimen in this region. Also, molecular testing proved effective for rapid identification of resistance-associated mutations.

Pancreatic ductal adenocarcinoma (PDAC) remains a high-burden disease worldwide with increasing incidence, poor prognosis, and high mortality. Complete surgical resection is the only potentially curative treatment; however, due to a lack of symptoms in the early stages, most patients have advanced disease when diagnosed. Type 2 diabetes mellitus (T2DM) is a significant health concern characterized by hyperglycemia, insulin resistance, and impairment in insulin secretion. T2DM is linked with PDAC, sharing a complex bidirectional relationship. Therefore, dual causality between the two diseases represents significant challenges in practice, distinguishing existing T2DM as a PDAC risk factor from newly onset, potentially pancreatic cancer-related diabetes (PCRD). Evidence showed that new-onset diabetes (NOD) may serve as a biomarker for early diagnosis of PDAC, and several risk prediction models were developed to identify high-risk patients for further intervention. Although early PDAC detection is important, widespread screening is not currently recommended for T2DM patients due to a lack of cost-effective, efficient screening modalities. However, further risk stratification in diabetic patients is warranted to support a targeted screening strategy with economic viability. Diabetes confers ≈2-fold PDAC risk overall, with the highest relative risk in the first 2–3 years after diagnosis. Strategies using clinical signs (age ≥50–60 years, unintentional weight loss, rapid HbA1c escalation/insulin initiation) and predictive risk scores (e.g., ENDPAC) can triage NOD patients for magnetic resonance imaging/computed tomography (MRI/CT) and endoscopic ultrasound (EUS). A targeted screening approach may allow early diagnosis that could improve the prognosis of PDAC patients. This narrative review aims to synthesize current evidence linking T2DM and PDAC; delineate risk factors within diabetes populations; appraise predictive models and biomarkers for differentiating PCRD from typical T2DM; outline pragmatic, risk-adapted screening strategies, especially for NOD, and identify additional areas where further research is needed.

Background/Objectives: Access to healthcare services was significantly restricted during the COVID-19 pandemic, leading to changes in the management of hepatocellular carcinoma (HCC). However, limited research has examined how these changes evolved post-pandemic. This study evaluated the impact of the pandemic at a tertiary center in Romania, focusing on diagnosis rates, treatments, and survival outcomes. Methods: A retrospective study conducted at Timișoara County Hospital divided patients into three equal cohorts of 23 months each: the pre-pandemic period (PreP: 1 May 2018–31 March 2020), the pandemic period (PandP: 1 April 2020–28 February 2022), and the post-pandemic period (PostP: 1 March 2022–31 January 2024). Newly diagnosed HCC cases were evaluated for the tumor stage, biological markers, and treatment received during each period. A survival census was conducted nine months after the diagnosis. Results: During the PandP and PostP periods, the numbers of newly diagnosed HCC cases decreased to 58 cases (p < 0.001) and 64 cases (p < 0.005), respectively, representing reductions of 38.3% and 31.9% compared to the PreP period, which had 94 cases. The proportion of patients in the BCLC-B stage increased from 31.9% in the PreP period to 50% during the PandP period (p = 0.0401), with fewer BCLC-A-0 cases (17% vs 5.1%; p = 0.059) during PandP. The tumor characteristics, BCLC classification, and TNM staging showed no significant differences between the PreP and PostP periods. Systemic therapy was the most commonly used treatment (39.7–50%). No significant differences were observed across treatment types when comparing all three periods (p > 0.05). The median follow-up times in the PreP, PandP, and PostP periods were 157.5, 159.5, and 183.5 days, respectively, with no statistically significant differences. The survival curve showed no statistically significant differences in survival between the groups at the nine-month follow-up (p > 0.05). Conclusions: The COVID-19 pandemic decreased HCC diagnoses, with only a partial rebound in the PostP period that did not reach PreP levels. While the PandP period showed worsening BCLC staging and an increase in tumor numbers, the tumor stage and treatment in the PostP period were similar to those in the PreP period. Similarly, the nine-month survival rates remained similar across all three periods.
