Colorectal cancer (CRC) represents a significant global health burden, ranking as the third most frequently diagnosed malignancy worldwide. Emerging evidence has established a compelling association between gut microbiota dysbiosis and CRC pathogenesis, revealing complex mechanisms through which specific bacterial communities modulate carcinogenesis. This comprehensive review synthesizes current knowledge on the mechanistic contributions of gut microbiota to CRC development, with particular emphasis on key pathogenic bacteria including Fusobacterium nucleatum, Bacteroides fragilis, and Escherichia coli. We examine the molecular pathways through which these microorganisms promote tumorigenesis, including chronic inflammation induction, immune response modulation, metabolic reprogramming, and direct genotoxic effects. Furthermore, we discuss the therapeutic implications of microbiota-targeted interventions and the potential utility of microbial biomarkers for early CRC detection. Understanding the intricate host–microbiota interactions in CRC pathogenesis may facilitate the development of novel preventive strategies and therapeutic approaches for this devastating disease.

Acute necrotizing pancreatitis (ANP), characterized by necrosis of pancreatic and/or peripancreatic tissues, is a potentially severe and life-threatening complication of acute pancreatitis, exhibiting a considerable mortality rate, particularly in the presence of infection, with rates ascending to 20–30%. Contrast-enhanced computed tomography is the definitive diagnostic standard, although treatment is determined by illness severity and the presence of secondary infection. The management of this condition has undergone considerable evolution, transitioning from initial surgical intervention to a more progressive, minimally invasive strategy. Initial management emphasizes aggressive fluid resuscitation, nutritional support, and monitoring of organ dysfunction. Infected necrosis is a critical factor influencing prognosis and requires intervention, typically starting with percutaneous drainage or endoscopic necrosectomy prior to evaluating surgical debridement. Recent advancements, such as the implementation of endoscopic and minimally invasive techniques, have enhanced outcomes by decreasing morbidity and mortality linked to open surgery. Despite these advancements, optimal treatment strategies are patient-specific and necessitate a multidisciplinary approach. Additional research is necessary to enhance guidelines and optimize patient outcomes.

Background/Objectives: Dystonia is a neurological movement disorder characterized by involuntary muscle contractions that lead to abnormal movements and postures; it has a major impact on patients’ health-related quality of life (HRQoL). The aim of this study was to examine the HRQoL of Romanian patients with dystonia using the EQ-5D-5L instrument. Methods: Responses to the EQ-5D-5L and the visual analogue scale (VAS) were collected alongside demographic and clinical characteristics. Health profiles were analyzed via the metrics of the EQ-5D-5L, severity levels, and age groups. Using Shannon’s indexes, we calculated informativity both for patients’ health profile as a whole and each individual dimension. Level sum scores (LSS) of the EQ-5D-5L were calculated and compared with scores from the EQ-5D-5L index and VAS. The HRQoL measures were analyzed through demographic and clinical characteristics. Descriptive statistics, Spearman correlation, and non-parametric tests (Mann–Whitney U or Kruskall–Wallis H) were used. The level of agreement between HRQoL measures was assessed using their intraclass correlation coefficient (ICC) and Bland–Altman plots. Results: A sample of 90 patients was used, around 75.6% of whom were female patients, and the mean age at the beginning of the survey was 58.7 years. The proportion of patients reporting “no problems” in all five dimensions was 10%. The highest frequency reported was “no problems” in self-care (66%), followed by “no problems” in mobility (41%). Shannon index and Shannon evenness index values showed higher informativity for pain/discomfort (2.07 and 0.89, respectively) and minimal informativity for self-care (1.59 and 0.68, respectively). The mean EQ-5D-5L index, LSS, and VAS scores were 0.74 (SD = 0.26), 0.70 (SD = 0.24), and 0.61 (SD = 0.21), respectively. The Spearman correlations between HRQoL measures were higher than 0.60. The agreement between the EQ-5D-5L index and LSS values was excellent (ICC = 0.970, 95% CI = 0.934–0.984); the agreement was poor-to-good between the EQ-5D-5L index and VAS scores (ICC = 683, 95% CI = 0.388–0.820), and moderate-to-good between the LSS and VAS scores (ICC = 0.789, 95% CI = 0.593–0.862). Conclusions: Our results support the utilization of the EQ-5D-5L instrument in assessing the HRQoL of dystonia patients, and empirical results suggest that the EQ-5D-5L index and LSS measure may be used interchangeably. The findings from this study highlight that HRQoL is complex in patients with dystonia, particularly across different age groups.

Introduction: From the observation of a negative relationship between UV-B exposure and cancer rates, we hypothesized that vitamin D (VD) may play a protective role in oncogenesis. Moreover, repurposing a well-known and relatively safe drug for conditions with dismal prospects, such as pancreatic ductal adenocarcinoma (PDAC), is a tempting idea. Thus, we aimed to summarize the current knowledge regarding the role of VD in the prevention and treatment of PDAC. Methods: We conducted a systematic review of VD and PDAC using Medline-indexed studies accessed through PubMed as the primary data source. This study aimed to identify articles focusing on the role of VD as a risk and prognostic factor for PDAC, mechanistic studies evaluating the effects of VD or vitamin D analogs (VDAs) in PDAC models, and clinical trials on VDAs in PDAC. After the screening, 97 studies were included in the final manuscript. Conclusion: Even though the results from epidemiologic studies were contradictory, basic research has demonstrated that VD can act on PDAC cells either directly, inhibiting proliferation, apoptosis, EMT, migration, invasion, and stemness, or indirectly, through stromal remodeling. A better understanding of the consequences of VD-induced tumor–stroma cross-talk alterations is needed to determine whether VD/VDAs can be used to our own advantage in the treatment of PDAC.

Esophageal anastomotic fistula (AF) is a frequent and severe complication of an esophagectomy due to esophageal or eso-gastric junction cancer, regardless of the selected surgical technique. AF is usually treated by endoscopic stent placement. Objectives: This study aims to examine the efficacy of stents in the treatment of AF, analyzing the healing period and the factors that contribute to its delay. Methods: We collected data from 55 patients who underwent stent implantation for AF, and analyzed multiple variables related to patient healing time and surgical technique with two primary endpoints: post-stenting hospital stay and the time of stent usage until fistula closure. The patients were divided into three groups based on the anastomosis type (eso-gastric anastomosis, eso-gastric cervical anastomosis and eso-jejunal anastomosis) and they were compared using the primary endpoints. Results: Our findings show the differences between the three groups, with a longer hospital stay for eso-gastric anastomosis, and an extended time of fistula closure in the case of eso-gastric cervical anastomosis. We also found a significant correlation between the size of the fistula and the hospital stay (R = 0.4, p < 0.01). Regarding patients’ risk factors, our results show an extended post-stenting hospital stay for those patients that underwent preoperative radiotherapy. Conclusions: Our results offer an extended view of the efficiency, hospitalization duration and healing time for esophageal anastomotic fistula, and reveal some of the factors that interfere with its resolution.

The integration of artificial intelligence (AI) into healthcare, particularly in the field of gastroenterology, marks a significant advancement in the diagnosis and treatment of pancreatic disorders. This narrative review explores the application of AI in enhancing Endoscopic Ultrasound (EUS) imaging techniques for pancreatic pathologies, focusing on developments over the past decade. Through a comprehensive literature search across several scientific databases, including PubMed, Google Scholar, and Web of Science, this paper selects and analyzes 50 studies that highlight the role, benefits, precision rates, and limitations of AI in EUS. The findings suggest that AI not only improves the quality of endoscopic procedures, as acknowledged by a majority of gastroenterologists in the UK and USA, but also offers a promising future for medical diagnostics and treatment, potentially addressing the shortage of specialists and reducing morbidity and mortality rates. Despite AI’s infancy in clinical applications and the ethical concerns regarding data privacy, its integration into EUS has enhanced diagnostic accuracy and provided minimally invasive therapeutic alternatives. This review underscores the necessity for further clinical data to evaluate the applicability and reliability of AI in healthcare, advocating for a collaborative approach between physicians and AI technologies to revolutionize the traditional clinical diagnosis and expand treatment possibilities in gastroenterology.
