Oxidative stress (OS) and inflammation are known to play an important role in colorectal cancer (CRC). This study analyzed tumor, inflammatory and OS markers in CRC patients and in a control group. In addition, the evolution of these markers was evaluated after one-year of follow-up treatment.

Oxidative stress (OS) and inflammation are known to play an important role in chronic diseases, including cancer, and specifically colorectal cancer (CRC). The main objective of this study was to explore the diagnostic potential of OS markers in patients with CRC, which may translate into an early diagnosis of the disease. To do this, we compared results with those in a group of healthy controls and assessed whether there were significant differences.

The chronic low-grade inflammation widely associated with obesity can lead to a prooxidant status that triggers mitochondrial dysfunction. To date, Roux-en-Y gastric bypass (RYGB) is considered the most effective strategy for obese patients. However, little is known about its molecular mechanisms.

Oxidative stress (OS) and inflammation have been related to colorectal cancer (CRC), but the influence of the Mediterranean diet (MD) on these parameters is unknown. Therefore, the aim of this study was to determine the association between adherence to the MD and markers of OS and DNA damage in CRC patients and to study the influence of adherence to the MD on metabolic and tumor-related factors. This prospective observational study included a total of 80 patients diagnosed with CRC.

Obesity is characterized by low-grade chronic inflammation, metabolic overload, and impaired endothelial and cardiovascular function. Roux-en-Y gastric bypass (RYGB) results in amelioration of the pro-oxidant status of leukocytes and the metabolic profile. Nevertheless, little is known about the precise mechanism that drives systemic and metabolic improvements following bariatric surgery.

Purpose: This study aimed to validate the World Society for Emergent Surgery (WSES) scale for the management of acute left-sided colonic diverticulitis (ALCD).

Methods: An observational study based on a prospective database of patients with ultrasound (US) and computerized tomography (CT) confirmed ALCD was conducted at our center from April 2018 to May 2019. The primary outcome was the success rate of outpatient management.

The role of oxidative stress (OS) in cancer is a matter of great interest due to the implication of reactive oxygen species (ROS) and their oxidation products in the initiation of tumorigenesis, its progression, and metastatic dissemination. Great efforts have been made to identify the mechanisms of ROS-induced carcinogenesis; however, the validation of OS byproducts as potential tumor markers (TMs) remains to be established. This interventional study included a total of 80 colorectal cancer (CRC) patients and 60 controls.

Objective: To prospectively assess the diagnostic value of intestinal ultrasound (US) compared to computerized tomography (CT) in differentiating uncomplicated and complicated acute colonic diverticulitis (ACD).

Materials And Methods: During a period of 14 months patients referred to the department of Radiology with clinical suspicion of ACD underwent an US examination. All confirmed US ACD diagnosis were included and subsequently underwent an emergency abdominal CT, used as gold standard.

Neuroendocrine tumors (NET) are a heterogeneous group of neoplasms that originate in tissues derived from the neural crest, whose characteristic feature is the expression of neuroendocrine markers and somatostatin receptors. Here, we present the case of a patient with a surgically intervened small bowel NET. Focal uptake was identified in the unresected mesentery in the scintigraphy of somatostatin receptors (99mTc-Tektrotyd).

Obesity is a low-grade inflammatory condition affecting a range of individuals, from metabolically healthy obese (MHO) subjects to type 2 diabetes (T2D) patients. Metformin has been shown to display anti-inflammatory properties, though the underlying molecular mechanisms are unclear. To study whether the effects of metformin are mediated by changes in the inflammasome complex and autophagy in visceral adipose tissue (VAT) of obese patients, a biopsy of VAT was obtained from a total of 68 obese patients undergoing gastric bypass surgery.

Little is known about the mechanisms underlying the cardioprotective effect of Roux en-Y gastric bypass (RYGB) surgery. Therefore, the aim of the present study was to investigate whether weight loss associated with RYGB improves the oxidative status of leukocytes and ameliorates subclinical atherosclerotic markers. This is an interventional study of 57 obese subjects who underwent RYGB surgery.

Introduction: The present study aimed to evaluate the short- and mid-term outcomes of laparoscopic colon-first staged resection for colorectal cancer (CRC) and colorectal cancer liver metastases (CRCLM).

Methods: This study included patients with metastatic CRC who underwent laparoscopic surgical staged resection for the primary tumor and CRCLM between June 2013 and December 2018. Data collection included the baseline patient's and tumor features, the perioperative and histopathologic outcomes from both surgical procedures, and the oncologic follow-up.

Background & Aims: It is known that pinitol acts as a mediator of the insulin-signaling pathway, though little is known about its anti-inflammatory effect in human obesity. Therefore, this study aimed to evaluate the effect of pinitol on peripheral blood mononuclear cells (PBMCs) and visceral (VAT) and subcutaneous adipose tissues (SAT), focusing on the involvement of endoplasmic reticulum (ER) stress and sirtuin 1 (SIRT1).

Methods: In the intervention study, thirteen obese subjects consumed a pinitol-enriched beverage (PEB) for 12 weeks.

Necrotizing fasciitis is a critical illness involving skin and soft tissues, which may develop after blunt abdominal trauma causing abdominal wall hernia and representing a great challenge for physicians. A 52-year-old man was brought to the emergency department after a road accident, presenting blunt abdominal trauma with a large non-reducible mass in the lower-right abdomen. A first, CT showed abdominal hernia without signs of complication.
