Objectives: Liver steatosis is one of the main causes of liver disease with several clinical implications, such as steatohepatitis, liver cirrhosis, and hepatocellular carcinoma. It is associated with increased cardiovascular risk. Reliable, non-invasive methods to classify and evaluate improvement or worsening of liver steatosis at the diagnosis and during follow-up are therefore essential. This study aims to evaluate the accuracy of ultrasound fat fraction (USFF) in a population of patients with moderate to morbid obesity. Method: A total of 95 obese patients were evaluated for liver steatosis with ultrasound visual assessment and USFF measurement using the Samsung RS85 Prestige system. 84 patients were included (exclusion criteria were morphological features of advanced liver disease or cirrhosis, active viral hepatitis, alcohol use disorder, liver enzymes alteration and heart failure) Based on the visual assessment, patients were classified into four categories: absent, mild, moderate, and severe steatosis. The distribution of USFF values across groups was analyzed using one-way ANOVA with post-hoc comparisons. Receiver Operating Characteristic (ROC) curves were generated, and the Youden index was applied to determine optimal USFF cut-off points for each steatosis grade. Results: Mean USFF values increased progressively across the severity spectrum and significant differences in mean USFF values were observed across all four steatosis grades groups (p < 0.001). Based on the Youden index, the following cut-offs have been proposed: no steatosis USFF < 7.33, mild steatosis USFF < 11.66, moderate steatosis USFF < 16.30. Conclusions: Our findings suggest that USFF may offer a valuable tool for objectively quantifying liver fat content with a more easily comparable parameter, improving the accuracy of steatosis grading and follow-up.

Ascites, a common complication of portal hypertension in cirrhosis, is characterized by the accumulation of fluid within the peritoneal cavity. While traditional theories focus on hemodynamic alterations and renin–angiotensin–aldosterone system (RAAS) activation, recent research highlights the intricate interplay of molecular and cellular mechanisms. Inflammation, mediated by cytokines (interleukin-1, interleukin-4, interleukin-6, tumor necrosis factor-α), chemokines (chemokine ligand 21, C-X-C motif chemokine ligand 12), and reactive oxygen species (ROS), plays a pivotal role. Besides pro-inflammatory cytokines, hepatic stellate cells (HSCs), sinusoidal endothelial cells (SECs), and smooth muscle cells (SMCs) contribute to the process through their activation and altered functions. Once activated, these cell types can worsen ascites accumulationthrough extracellular matrix (ECM) deposition and paracrine signals. Besides this, macrophages, both resident and infiltrating, through their plasticity, participate in this complex crosstalk by promoting inflammation and dysregulating lymphatic system reabsorption. Indeed, the lymphatic system and lymphangiogenesis, essential for fluid reabsorption, is dysregulated in cirrhosis, exacerbating ascites. The gut microbiota and intestinal barrier alterations which occur in cirrhosis and portal hypertension also play a role by inducing inflammation, creating a vicious circle which worsens portal hypertension and fluid accumulation. This review aims to gather these aspects of ascites pathophysiology which are usually less considered and to date have not been addressed using specific therapy. Nonetheless, it emphasizes the need for further research to understand the complex interactions among these mechanisms, ultimately leading to targeted interventions in specific molecular pathways, aiming towards the development of new therapeutic strategies.

Acute pancreatitis is a complex inflammatory disease with significant morbidity and mortality. Despite advances in its management, the role of antibiotics in the prophylaxis and treatment of acute pancreatitis remains controversial. The aim of this comprehensive review is to analyze current evidence on the use of antibiotics in acute pancreatitis, focusing on prophylactic and therapeutic strategies. Prophylactic use aims to prevent local and systemic infections. However, recent studies have questioned the routine use of antibiotics for prophylaxis and highlighted the potential risks of antibiotic resistance and adverse effects. In selected high-risk cases, such as infected necrotizing pancreatitis, prophylactic antibiotic therapy may still be beneficial. As for therapeutic use, antibiotics are usually used to treat infected pancreatic necrosis and extrapancreatic infections. When selecting an antibiotic, the microbiologic profile and local resistance patterns should be considered. Combination therapy with broad-spectrum antibiotics is often recommended to cover both Gram-positive and Gram-negative pathogens. Recent research has highlighted the importance of individualized approaches to antibiotic use in acute pancreatitis and underscored the need for a tailored approach based on patient-specific factors. This review also highlights the potential role of new antimicrobial agents and alternative strategies, such as probiotics, in the management of acute pancreatitis.

Background: Up to one-third of patients with gastroesophageal reflux disease (GERD) have persistent symptoms despite proton-pump inhibitor (PPI) therapy. E-Gastryal® + MgAlg (Aurora Biofarma, Italy) is a mucosal protective agent that enhances barrier function against acid and non-acidic reflux. This study assessed its efficacy in combination with omeprazole versus omeprazole alone and as maintenance therapy. Methods: Patients with symptomatic GERD and Grade A reflux esophagitis confirmed by endoscopy were randomized to receive omeprazole 20 mg plus E-Gastryal® + MgAlg or omeprazole 20 mg alone. The primary endpoint was the number of rescue medications used over 28 days. Secondary endpoints included symptom relief and quality-of-life assessments using the Reflux Symptom Index (RSI), Gastroesophageal Reflux Disease Impact Scale (GIS), GERD-Health-Related Quality of Life (GERD-HRQL), and Global Assessment of Performance (IGAP). Results: Ninety-six patients were included. The combination group used significantly fewer rescue medications (mean: 21 vs. 40.9 tablets; p = 0.002). At week 4, the combination group showed greater improvement in RSI, GIS, and GERD-HRQL scores (p < 0.001). Symptom relief was sustained during weeks 5–26 with E-Gastryal® + MgAlg alone. Conclusions: E-Gastryal® + MgAlg combined with omeprazole improves symptom control compared to PPI monotherapy. Continued use as maintenance therapy supports its role in long-term GERD management (NCT04130659).

Inflammatory bowel diseases (IBD), comprising Crohn’s disease and ulcerative colitis, are systemic and multifaceted disorders which affect other organs in addition to the gastrointestinal tract in up to 50% of cases. Extraintestinal manifestations may present before or after IBD diagnosis and negatively impact the intestinal disease course and patients’ quality of life, often requiring additional diagnostic evaluations or specific treatments. Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide. Current evidence shows an increased prevalence of NAFLD (and its more advanced stages, such as liver fibrosis and steatohepatitis) in IBD patients compared to the general population. Many different IBD-specific etiopathogenetic mechanisms have been hypothesized, including chronic inflammation, malabsorption, previous surgical interventions, changes in fecal microbiota, and drugs. However, the pathophysiological link between these two diseases is still poorly understood. In this review, we aim to provide a comprehensive overview of the potential mechanisms which have been investigated so far and highlight open issues still to be addressed for future studies.

Gut microbiota (GM) modulation can be investigated as possible solution to enhance recovery after COVID-19. An open-label, single-center, single-arm, pilot, interventional study was performed by enrolling twenty patients recently recovered from COVID-19 to investigate the role of a mixed probiotic, containing Lactobacilli, Bifidobacteria and Streptococcus thermophilus, on gastrointestinal symptoms, local and systemic inflammation, intestinal barrier integrity and GM profile. Gastrointestinal Symptom Rating Scale, cytokines, inflammatory, gut permeability, and integrity markers were evaluated before (T0) and after 8 weeks (T1) of probiotic supplementation. GM profiling was based on 16S-rRNA targeted-metagenomics and QIIME 2.0, LEfSe and PICRUSt computational algorithms. Multiple machine learning (ML) models were trained to classify GM at T0 and T1. A statistically significant reduction of IL-6 (p < 0.001), TNF-α (p < 0.001) and IL-12RA (p < 0.02), citrulline (p value < 0.001) was reported at T1. GM global distribution and microbial biomarkers strictly reflected probiotic composition, with a general increase in Bifidobacteria at T1. Twelve unique KEGG orthologs were associated only to T0, including tetracycline resistance cassettes. ML classified the GM at T1 with 100% score at phylum level. Bifidobacteriaceae and Bifidobacterium spp. inversely correlated to reduction of citrulline and inflammatory cytokines. Probiotic supplementation during post-COVID-19 may trigger anti-inflammatory effects though Bifidobacteria and related-metabolism enhancement.

CMV infection is still a matter of concern in IBD patients, especially regarding the disease’s relapse management. Why IBD patients, particularly those affected by ulcerative colitis, are more susceptible to CMV reactivation is not totally explained, although a weakened immune system could be the reason. Various techniques, ranging from serology to histology, can be employed to detect intestinal CMV infection; however, there is currently disagreement in the literature regarding the most effective diagnostic test. Furthermore, CMV involvement in steroid resistance has been broadly discussed, but whether CMV infection is a cause or consequence of the disease severity and, consequently, steroid refractoriness is still debated. Its potential contribution to the lack of response to advanced therapy and small molecules must be more valued and wholly explored. In this review, we look at the actual literature on CMV in IBD patients, and we suggest a pragmatic algorithm for clinical practice management of CMV infection.

Background: Chronic prostatitis/chronic pelvic pain syndrome (IIIB CP/CPPS) is a condition of unclear aetiology. Many approaches have been used without satisfactory results. The aim of this study is to evaluate the efficacy of once-daily 5 mg tadalafil in pain control and improving quality of life in patients affected by CP/CPPS. Methods: Twenty patients affected by chronic prostatitis according EAU (European Association of Urology) guidelines were evaluated for once-daily 5 mg tadalafil; 14 patients were eligible for the study. The validated Italian version of the NIH Chronic Prostatitis Symptom Index (NIH-CPSI) and the International Prostatic Symptom Score (IPSS) questionnaires were submitted to all the patients. Every patient underwent uroflowmetry and ultrasound prostatic volume at the beginning and at the end of the study. Results: All 14 patients eligible for the study reported an improvement of symptoms during therapy: statistically significant differences were reported in terms of NIH-CPSI (p < 0.000002) and IPSS (p < 0.0001) during follow-up evaluations. No statistically significant improvement of uroflowmetry parameters was reported during the treatment. Conclusions: In our study the daily use of 5 mg tadalafil improves symptoms and quality of life in patients affected by CP/CPPS after 4 weeks of therapy. A larger population of patients is needed to confirm the efficacy of this therapy in CP/CPPS.

Purpose To analyze postoperative complications after laparoscopic radical cystectomy (LRC) and evaluate its risk factors in a large prospective cohort built by the ESUT across European centers involved in minimally invasive urology in the last decade. Methods Patients were prospectively enrolled, and data were retrospectively analyzed. Only oncologic cases were included. There were no formal contraindications for LRC: Also patients with locally advanced tumors (pT4a), serious comorbidities, and previous major abdominal surgery were enrolled. All procedures were performed via a standard laparoscopic approach, with no robotic assistance. Early and late postoperative complications were graded according to the modified Clavien–Dindo classification. Multivariate logistic regression was performed to explore possible risk factors for developing complications. Results A total of 548 patients were available for final analysis, of which 258 (47 %) experienced early complications during the first 90 days after LRC. Infectious, gastrointestinal, and genitourinary were, respectively, the most frequent systems involved. Postoperative ileus occurred in 51/548 (9.3 %) patients. A total of 65/548 (12 %) patients underwent surgical re-operation, and 10/548 (2 %) patients died in the early postoperative period. Increased BMI ( p  = 0.024), blood loss ( p  = 0.021), and neoadjuvant treatment ( p  = 0.016) were significantly associated with a greater overall risk of experiencing complications on multivariate logistic regression. Long-term complications were documented in 64/548 (12 %), and involved mainly stenosis of the uretero-ileal anastomosis or incisional hernias. Conclusions In this multicenter, prospective, large database, LRC appears to be a safe but morbid procedure. Standardized complication reporting should be encouraged to evaluate objectively a surgical procedure and permit comparison across studies.
