Purpose: Food insecurity and colorectal cancer (CRC) are widely prevalent problems in the U.S. However, the long-term effects of food insecurity among people living with CRC are not well explored (e.g., risk of mortality). Methods: Data from the U.S. National Health and Nutrition Examination Survey (years 1999–2010) were linked with mortality data from the National Death Index up to 31 December 2019. Results: A total of 30,752 adults comprised the analytic sample; 222 were living with CRC and more than a tenth were food-insecure (11.6%). In our adjusted analysis, individuals who were food insecure and had CRC were 4.13 times more likely to die of any cause and 9.57 times more likely to die of cardiovascular diseases (compared to those without CRC and food insecurity). Conclusions: Colorectal cancer is among the top cancers diagnosed in American adults and more than a tenth of adult Americans with CRC live with food insecurity. Given the higher risk of mortality with co-occurring CRC and food insecurity, collaborative healthcare models can help address food insecurity and other social needs of people with CRC, and surveillance measures for food insecurity should be widely implemented across health systems.

Inflammatory bowel disease (IBD) represents a heterogenous and complex group of idiopathic chronic inflammatory conditions affecting the gastrointestinal tract and other extraintestinal systems with rising global incidences. The interplay of genetic predisposition and environmental factors contributes to its pathogenesis. Among the key cytokines implicated in IBD molecular alterations, IL-33 stands out for its multifaceted roles in both pathogenesis and repair mechanisms. IL-33, known for its action in initiating immune responses, is closely associated with Th2 immunity and is considered a potent inflammatory factor with dual functions, acting both as a pro-inflammatory cytokine and a transcriptional regulator. Primarily expressed by non-hematopoietic cells in the gastrointestinal tract, IL-33 interacts with its receptor, ST2, to modulate immune responses. In IBD, dysregulated IL-33 expression exacerbates mucosal inflammation, compromising barrier integrity and promoting tissue damage and fibrosis. Additionally, IL-33 plays a complex role in IBD-related colorectal cancer (CRC), affecting tumor progression and angiogenesis. This review summarizes the multifaceted roles of IL-33 in gastrointestinal health and disease, emphasizing its significance in the pathogenesis of IBD and CRC. Moreover, we thought it of interest to provide new insights into potential therapeutic avenues targeting IL-33 signaling for the management of these debilitating conditions.

A severe condition of sepsis can be a complication of necrotizing enterocolitis (NEC), which can occur in premature infants and becomes a medical challenge in the neonatal intensive care unit (NICU). It is a multifactorial intestinal disease (can affect both the small and large intestine) that can lead to ischemia of the intestinal tissues that evolves into acute organ necrosis. One of these factors is that different types of nutrition can influence the onset or the progression of the disease. Cow-milk-based infant formulas have been shown to cause it in premature infants more frequently than human milk. Recently, nutrition has been shown to be beneficial after surgery. Several issues still under study, such as the pathogenesis and the insufficient and often difficult therapeutic approach, as well as the lack of a common and effective prevention strategy, make this disease an enigma in daily clinical practice. Recent studies outlined the emerging role of the host immune system and resident gut microbiota, showing their close connection in NEC pathophysiology. In its initial stages, broad-spectrum antibiotics, bowel rest, and breastfeeding are currently used, as well as probiotics to help the development of the intestinal microbiota and its eubiosis. This paper aims to present the current knowledge and potential fields of research in NEC pathophysiology and therapeutic assessment.
严重的败血症可能是坏死性小肠结肠炎（NEC）的并发症，NEC 可发生在早产儿身上，成为新生儿重症监护室（NICU）的医疗难题。这是一种多因素肠道疾病（可影响小肠和大肠），可导致肠道组织缺血，进而演变为急性器官坏死。其中一个因素是不同类型的营养会影响疾病的发生或发展。与人奶相比，以牛乳为基础的婴儿配方奶粉更容易导致早产儿发病。最近，营养在手术后被证明是有益的。目前仍在研究的几个问题，如发病机理、治疗方法不足且往往困难重重，以及缺乏通用而有效的预防策略，使这种疾病成为日常临床实践中的一个谜。最近的研究概述了宿主免疫系统和常驻肠道微生物群的新作用，显示了它们在 NEC 病理生理学中的密切联系。在NEC的初期阶段，目前主要使用广谱抗生素、肠道休息和母乳喂养，以及益生菌来帮助肠道微生物群的发育和优生。本文旨在介绍有关 NEC 病理生理学和治疗评估的现有知识和潜在研究领域。

Introduction: Hepatectomy (HP) is, along with liver transplantation, the only potentially curative treatment for Hepatocellular Carcinoma (HCC). The high prevalence of Metabolic Syndrome (MS) may be causing a shift in the HCC spectrum. Hepatic Pedicle Clamping (HPC), used to reduce perioperative bleeding during HP, has been theorized to increase the risk of recurrence. Cytokeratin 19 (CK19) and glypican-3 (GLP-3) have been identified as markers of worse prognosis in HCC. Materials and Methods: A clinical and pathological review of 59 patients undergoing HP for HCC between 2005 and 2013 was performed. Chronic liver disease was observed in 53 patients (89.8%), with cirrhosis in 54.2% [most frequent etiologies: ethylism (47.5%), HCV (25.4%) and HBV (11.9%)]. MS was in 36% of patients. In addition, 95% of patients had Child–Pugh class A and 5% class B, and there was a median MELD of 8 (6–18). A single nodule was observed in 46 patients (78%) with an average size of 5.4 cm. Microscopic vascular invasion (MiVI) was in 49% of patients and macroscopic (MaVI) in 17. HPC was in 43 patients (74.1%). Statistical analysis was performed with SPSS™ 21.0. Survival tests (Kaplan–Meier, log-rank and Cox regression). Statistical significance was with p < 0.05. Results: Major morbidity in 22% of patients. Mortality in 5.1%. Median overall survival (OS) of 71 months and median disease-free survival (DFS) of 37. In a multivariate analysis: MaVI (p = 0.001), MiVI (p = 0.005) and HCV infection (p = 0.002) were associated with worse OS; MS was associated with better OS (p = 0.001); MaVI (p = 0.000), MiVI (p = 0.035) and HPC (p = 0.012) were associated with worse DFS. CK19+/GLP-3− (p = 0.007) and CK19−/GLP-3+ (p = 0.029) patients were associated with worse DFS and CK19−/GLP-3− (p = 0.031) with better DFS. Discussion/Conclusions: HPC was an independent factor of worse DFS. The ischemia-reperfusion injury (IRI) produced by HPC could promote a more angiogenic and angioinvasive phenotype of tumor cells, resulting in higher recurrence. HCV etiology was associated with worse OS. MS was associated with better OS, highlighting the importance of a hepatectomy in these cases. The combined detection of CK19 and GLP-3 was an independent prognostic factor in HCC patients allowing for the identification of more aggressive tumors.

Traditional cancer treatments have not significantly improved the survival rates for individuals with colorectal cancer. As a result, there is a dire need to explore novel treatment modalities that can target cancer-specific niches, transform cold colorectal tumors into hot ones, and disrupt the tumor niche. Therapeutic focused ultrasound, recognized for its capacity to induce thermal and mechanical impacts on tissue, can potentially eliminate cancer cells and elicit the body’s anticancer reaction by disrupting the tumor microenvironment. This article provides an overview of recent developments in employing therapeutic focused ultrasound (TFUS) to enhance the body’s natural defenses against colorectal cancers. It also discusses studies examining the utility of TFUS in treating colorectal cancer patients and recent research indicating its potential to stimulate the body’s anticancer response in various in vitro and in vivo colorectal cancer models. Furthermore, it explores the therapeutic effects of TFUS on the immune system in colorectal cancers. This article also highlights the safety and effectiveness of TFUS in managing colorectal cancer, providing relief from pain, and potentially improving survival rates. Given the indications that TFUS may bolster the body’s immune response and augment the impacts of TFUS therapy in clinical and preclinical colorectal cancer models, it has the potential to emerge as a pivotal tool in clinical settings.

Background: During esophagogastroduodenoscopy performed with colonoscopy, gastric and duodenal erythema, erosions, and ulcerations are often observed. This investigation was designed to review the prevalence of gastroduodenal lesions in patients who have undergone wireless capsule endoscopy using standard bowel cleansing preparations, but no endoscopy or sedation. Methods: A retrospective analysis was conducted on patients referred for capsule endoscopy. Records and capsule reports were reviewed for the patient demographics, preparation prescribed, procedural indications, and gastroduodenal findings. The preparations studied included polyethylene glycol lavage (PEG), PEG plus bisacodyl (PEG + bis), bisacodyl (bis), oral sulfate solution (OSS), and no prep. Results: Among the 1236 records, 498 (40.3%) were men and 738 (59.7%) were women. The mean age was 56 years +/− 18 years SD. The percentage of patients with lesions after any bowel preparation was 52.7% for gastric lesions and 23.6% for duodenal lesions. The percentage of patients with gastroduodenal lesions was 58.3% with prep, compared to 38.2% without prep. These findings were statistically significant, with an RR of 1.53 [1.19–1.94] (p-value = 0.00004). This difference was more pronounced in the OSS group RR of 1.65 [1.29–2.1] and bisacodyl group RR of 1.64 [1.25–2.15] compared to the PEG group RR of 0.95 [0.7–1.3]. Conclusions: This study showed that patients undergoing wireless capsule endoscopy who received bowel preparations had a significant increase in gastric and duodenal lesions. Of the preparations studied, OSS was associated with a greater number of gastroduodenal lesions, while PEG was the least associated with lesions, with an occurrence similar to the non-prep group. The clinical significance of these lesions remains undetermined. Endoscopists should be aware that preparations are associated with gastroduodenal lesions to avoid the misinterpretation and misdiagnosis of these lesions.

Recently, the bioactive potential of several functional ingredients and biomolecules has been evaluated regarding human and animal nutrition. The digestive process from food intake to absorption and metabolism are important events that induce changes in ingredients, which affect their bioactivity. Consequently, there is a need to assess the bioavailability and bioaccessibility of these compounds. The methodology for the simulation of the human gastrointestinal tract has been standardized (INFOGEST protocol), while a gastrointestinal protocol for other animals (e.g., ruminants or broilers) has yet to be established. However, INFOGEST allows us only to predict bioaccessibility, leaving a gap regarding a methodology able to assess bioavailability by mimicking intestinal permeability and absorption. Several approaches—including in vitro, ex vivo, in situ and in vivo methods—can be found in the literature, aiming to tackle transepithelial routes, but leading to different results concerning the bioefficiency of the compounds studied. Therefore, this review aims to assess the current state-of-the-art regarding monogastric intestinal dynamics, absorption, and permeability events. Moreover, it compiled methodologies for simulating intestinal absorption in several biological systems, while reasoning their advantages, disadvantages, applications in ingredient development and the existing gaps.

From a physiological standpoint, aging is a progressive reduction in each organ system’s capacity to maintain homeostasis in the face of illness or stressors. With advancing age, gastrointestinal (GI) symptoms and signs may increase, not only due to the aging processes but also to the superimposed effects of comorbidities, which can badly affect digestive functions (i.e., diabetes, malignancy, etc.) and environmental exposure. In general, gastrointestinal symptoms in older people more often underlie organic pathologies, while GI functional disorders are less frequently diagnosed in this age group. Moreover, gastrointestinal disease can also present in a nuanced and atypical manner, making the diagnostic hypothesis and, consequently, the correct diagnosis and therapy more challenging. In addition, with reference to this age group, the clinical implications of gastrointestinal pathologies can be more severe due to a decreased physiologic reserve, with a higher risk for malnutrition resulting in falls, depression, social isolation, and a deterioration of functional status. In this review, we focused on the most frequent GI tract disorders, highlighting the main age-related changes, their epidemiological, pathophysiological and clinical implications, and any differences with younger patients.

In this review, we focused on the most frequent GI tract disorders, highlighting the main age-related changes, their epidemiological, pathophysiological and clinical implications, and any differences with younger patients.","PeriodicalId":507842,"journal":{"name":"Gastrointestinal Disorders","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140255896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sarcomas are rare lesions and encompass a wide variety of entities, depending on their nature. In recent years new entities have been described and new knowledge, especially that provided by molecular studies, has been increasing. This makes it very difficult to be updated with all the described entities, since only some of the centers have the desired ancillary studies for the correct diagnosis. Some lesions are extremely rare and may appear once or twice during the lifetime of a general pathologist. When we refer to sarcomas of the gastrointestinal tract, the gastrointestinal stromal tumor (GIST) is the most well-known lesion that the pathologist will most frequently find in daily practice. This paper aims to comprehensively review the sarcomas associated with the gastrointestinal tract, emphasizing histopathology and going beyond GIST. This review highlights the histopathology of rare types of sarcomas so it may increase awareness of common and rare lesions, prompting an easy and effective diagnosis.
