Epidemiological data suggest that ceftriaxone may promote the emergence of commensal AmpC-overproducing Enterobacteriaceae because of a high biliary excretion. We tested this hypothesis in hospitalized patients either treated by ceftriaxone alone or receiving no antibiotics. Hospitalized patients with no previous antibiotics or hospitalization in the last 3 months, treated only with ceftriaxone, were prospectively included. For each ceftriaxone-treated patient, a control patient receiving no antibiotics was included...

Worldwide, colon cancer is among the most common cancer entities. Understanding the molecular background is the key to enable accurate stage determination, which is crucial to assess optimal therapy options. The search for preoperative biomarkers is ongoing. In recent years, several studies have proposed a diagnostic and prognostic role for miRNAs in cancer. Aim of this study was to evaluate miRNA expression patterns correlating with tumor stage, especially lymph node metastasis, in primary colon carcinoma tissue...

BACKGROUND: Major abdominal surgery, including colorectal cancer (CRC) surgery, leads to systemic inflammatory response syndrome that can be detected and monitored with inflammatory markers testing. The aims of the study were to evaluate the usefulness of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1), interleukin-6 (IL-6), procalcitonin (PCT), and C-reactive protein (CRP) in following the inflammatory response in CRC surgery and postoperative period, as well as to determine if duration of the surgery and the time that the colon has been opened during the surgery (open colon time [OCT]) reflect a larger surgical stress through inflammatory markers rise...

Background: The stomach is an underestimated key interface between the ingesta and the digestive system, affecting the digestion and playing an important role in several endocrine functions. The quality of starter microbiota and the early life feeding of medium chain triglycerides may affect porcine gastric maturation. Two trials (T1, T2) were carried out on 12 and 24 cesarean-delivered piglets (birth, d0), divided over two microbiota treatments, but slaughtered and sampled at two or three weeks of age, respectively...

Fluoride exposure is widespread, with drinking water commonly containing natural and artificially added sources of the ion. Ingested fluoride undergoes absorption across the gastric and intestinal epithelia. Previous studies have reported adverse gastrointestinal effects with high levels of fluoride exposure. Here, we examined the effects of fluoride on the transepithelial ion transport and resistance of three intestinal epithelia. We used the Caco-2 cell line as a model of human intestinal epithelium, and rat and mouse colonic epithelia for purposes of comparison...

A 76-year-old male underwent endoscopic mucosal resection for a stage T1 tumour of the sigmoid colon. We performed laparoscopic sigmoidectomy through 5 ports using needlescopic instruments. The resected specimen was extracted from the abdominal cavity transanally. After attaching an anvil to the sigmoidal stump, the rectal stump was reclosed using an endoscopic linear stapler, and then, colorectal anastomosis was conducted using the double stapling technique. Performing transanal specimen extraction using needlescopic forceps improves aesthetic outcomes and reduces post-operative pain and the risk of abdominal incisional hernias...

Foodborne disease caused by Salmonella Enteritidis (SE) is one of the important public health and economic concerns. A study was conducted to determine the effect of supplementation with 2-nitroethanol (NE) and 2-nitropropanol (NP) on Salmonella recovery of internal organs as well as on the immune gene expression in the ileum of laying hens. Thirty-six White Leghorns were orally gavaged with nalidixic acid resistant Salmonella Enteritidis (SENR). Hens were housed individually in wire-laying cages and randomly assigned to six dietary treatments: T1 = SENR unchallenged (negative control), T2 = SENR challenged (positive control), T3 = SENR challenged + 100 ppm NE, T4 = SENR challenged + 200 ppm NE, T5 = SENR challenged + 100 ppm NP, and T6 = SENR challenged + 200 ppm NP...

The beneficial effects of consumption of berry fruits on a range of chronic diseases has been attributed (at least in part) to the presence of unique phytochemicals. Recently, we identified novel ursolic acid-based triterpenoid glycosides (TTPNs) in raspberry fruit and demonstrated their survival in human ileal fluids after feeding which confirmed their colon-availability in vivo. In this paper, in vitro digestion studies demonstrated that certain TTPNs were stable under gastrointestinal conditions and confirmed that these components may have been responsible for bioactivity noted in previous studies...

The objective of this study was to evaluate the potential of eight fungal isolates obtained from soils in rice crops for straw degradation in situ. From the initial eight isolates, Pleurotus ostreatus T1.1 and Penicillium sp. HC1 were selected for further characterization based on qualitative cellulolytic enzyme production and capacity to use rice straw as a sole carbon source. Subsequently, cellulolytic, xylanolytic, and lignolytic (Pleurotus ostreatus) activity on carboxymethyl cellulose, oat xylan, and rice straw with different nitrogen sources was evaluated...

OBJECTIVES: CD43 is normally expressed only on the surface of leukocytes, and is considered a sensitive and specific marker for hematologic malignancies. As such, it may have diagnostic utility in confirming hematolymphoid lineage in cases that are negative for CD45. Aberrant CD43 expression has been described in non-hematopoietic tumors, although literature data on this topic is variable and sometimes contradictory. To clarify and expand on existing literature findings, we evaluated CD43 expression by immunohistochemistry (IHC) in a large cohort (307) of non-hematopoietic neoplasms, including poorly differentiated malignancies...

BACKGROUND: According to the current official guidelines, at least 12 lymph nodes (LNs) are qualified as an adequate sampling for colon cancer patients. However, patients evaluated with less nodes were still common in the United States, and the prevalence of positive nodal disease may be under-estimated because of the false-negative assessment. In this study, we present a statistical model that allows preoperative determination of the minimum number of lymph nodes needed to confirm a node-negative disease with certain confidence...

The incidence of colorectal cancer (CRC) is lower in women than in men, and sex steroids can be considered contributing factors because oral contraception usage and estrogen replacement therapy are associated with decreased risk. Conversely, colorectal polyp development in familial adenomatous polyposis (FAP) begins during puberty. The objectives were to evaluate the relationship between the expression of these hormone receptors and adenoma-carcinoma progression, CRC stage and overall survival. We studied 120 A...
