The Implications of Noncoding RNAs in the Evolution and Progression of Nonalcoholic Fatty Liver Disease (NAFLD)-Related HCC.

Nonalcoholic fatty liver disease (NAFLD) is the most prevalent liver pathology worldwide. Meanwhile, liver cancer represents the sixth most common malignancy, with hepatocellular carcinoma (HCC) as the primary, most prevalent subtype. Due to the rising incidence of metabolic disorders, NAFLD has become one of the main contributing factors to HCC development. However, although NAFLD might account for about a fourth of HCC cases, there is currently a significant gap in HCC surveillance protocols regarding noncirrhotic NAFLD patients, so the majority of NAFLD-related HCC cases were diagnosed in late stages when survival chances are minimal. However, in the past decade, the focus in cancer genomics has shifted towards the noncoding part of the genome, especially on the microRNAs (miRNAs) and long noncoding RNAs (lncRNAs), which have proved to be involved in the regulation of several malignant processes. This review aims to summarize the current knowledge regarding some of the main dysregulated, noncoding RNAs (ncRNAs) and their implications for NAFLD and HCC development. A central focus of the review is on miRNA and lncRNAs that can influence the progression of NAFLD towards HCC and how they can be used as potential screening tools and future therapeutic targets.

CT-Based Radiomic Analysis May Predict Bacteriological Features of Infected Intraperitoneal Fluid Collections after Gastric Cancer Surgery.

The ability of texture analysis (TA) features to discriminate between different types of infected fluid collections, as seen on computed tomography (CT) images, has never been investigated. The study comprised forty patients who had pathological post-operative fluid collections following gastric cancer surgery and underwent CT scans. Patients were separated into six groups based on advanced microbiological analysis of the fluid: mono bacterial (n = 16)/multiple-bacterial (n = 24)/fungal (n = 14)/non-fungal (n = 26) infection and drug susceptibility tests into: multiple drug-resistance bacteria (n = 23) and non-resistant bacteria (n = 17). Dedicated software was used to extract the collections' TA parameters. The parameters obtained were used to compare fungal and non-fungal infections, mono-bacterial and multiple-bacterial infections, and multiresistant and non-resistant infections. Univariate and receiver operating characteristic analyses and the calculation of sensitivity (Se) and specificity (Sp) were used to identify the best-suited parameters for distinguishing between the selected groups. TA parameters were able to differentiate between fungal and non-fungal collections (ATeta3, p = 0.02; 55% Se, 100% Sp), mono and multiple-bacterial (CN2D6AngScMom, p = 0.03); 80% Se, 64.29% Sp) and between multiresistant and non-multiresistant collections (CN2D6Contrast, p = 0.04; 100% Se, 50% Sp). CT-based TA can statistically differentiate between different types of infected fluid collections. However, it is unclear which of the fluids' micro or macroscopic features are reflected by the texture parameters. In addition, this cohort is used as a training cohort for the imaging algorithm, with further validation cohorts being required to confirm the changes detected by the algorithm.

Computed Tomography for the Diagnosis of Intraperitoneal Infected Fluid Collections after Surgery for Gastric Cancer. Role of Texture Analysis.

BACKGROUND AND AIMS: Several computed tomographic (CT) imaging features have been proposed to describe the infection of postoperative abdominal fluid collections; however, these features are vague, and there is a significant overlap between infected and non-infected collections. We assessed the role of textural parameters as additional diagnostic tools for distinguishing between infected and non-infected peritoneal collections in patients operated for gastric cancer. METHODS: From 527 patients operated for gastric cancer, we retrospectively selected 82 cases with intraperitoneal collections who underwent CT exams. The fluid component was analyzed through a novel method (texture analysis); different patterns of pixel intensity and distribution were extracted and processed through a dedicated software (MaZda). A univariate analysis comparing the parameters of texture analysis between the two groups was performed. Afterwards, a multivariate analysis was performed for the univariate statistically significant parameters. RESULTS: The study included 82 patients with bacteriologically verified infected (n=40) and noninfected (n=42) intraperitoneal effusions. The univariate analysis evidenced statistically significant differences between all the parameters involved. The multivariate analysis highlighted 10 parameters as being statistically significant, adjusted to Bonferroni correction. CONCLUSIONS: Our evidence supports the fact that textural analysis can be used as a complementary diagnostic tool for the detection of infected fluid collections after gastric cancer surgery. Further studies are required to validate the accuracy of this method.

A combined laparoscopic and endoscopic approach for the removal of a gastric foreign body. A case report and review of the literature.

BACKGROUND AND AIM: Foreign bodies that are ingested and will not pass spontaneously through the gastrointestinal tract, need to be removed either endoscopically or surgically. Surgery will be required when endoscopy alone fails to retrieve the foreign body. In this study, we aimed to present our experience with an combined minimal invasive approach for the removal of a gastric foreign body and to review the medical literature on the complexities related to its management. METHODS: We report a successful technique represented by a combined laparoscopic and endoscopic approach for the retrieval of a gastric foreign body. A 51 year old male patient, with a longstanding psychiatric history, who ingested a folded bank card with suicidal purpose, had the foreign body removed using this combined minimal invasive approach. RESULTS: The operating time was 150 minutes, there was no blood loss and no perioperative complications. The patient fulfilled the discharge criteria on the 3rd postoperative day DISCUSSION : The approach for ingested foreign bodies should be considered for each patient independently, depending on the characteristics, location and existence of complications of the retained object. CONCLUSION: This combined minimal invasive technique is safe and feasible, with excellent results for the retrieval of large, non-malleable gastric foreign bodies. KEY WORDS: Endoscopy, Foreign body, Laparoscopy, Removal.

Inferior Pancreatico-Duodenal Artery Aneurysm with Superior Mesenteric Artery Stenosis.

Pancreatico-duodenal artery aneurysm (PDAA) associated with stenosis or occlusion of the celiac trunk is a rare condition. Furthermore, PDAAs associated with stenosis of the superior mesenteric artery (SMA) are even more uncommon, with only six cases reported in the literature. We report a case of a 61-year old male patient who presented with hematemesis, haematochezia and haemorrhagic shock. The upper gastrointestinal endoscopy revealed an ulcerous lesion at the third portion of the duodenum, without achieving the haemostasis. The emergency laparotomy (suture of the lesion and gastro-entero-anastomosis) permitted temporary haemostasis. Computed tomography angiography identified the PDAA ruptured into the third portion of the duodenum and the SMA stenosis at its origin; a dense network of collateral vessels was present. The patient was successfully managed with coil embolization. Short and mid-term follow-up were without incidents.

Laparoscopic cholecystectomy for overlooked duplicated gallbladder. A case report and review of the literature.

INTRODUCTION: Duplicated gallbladder is a seldom surgical finding that frequently eludes detection on routine preoperative imaging and in some circumstances it might be even overlooked during surgery. Identification of this anomaly and its various types is important in order prevent post operative complications and recurrent symptoms after cholecystectomy. PRESENTATION OF CASE: We present a female patient with biliary simptomatology who had previous cholecystectomy. Preoperatory imaging (MRCP) suspects a duplicated gallbladder which was confirmed intraoperatory and cholecystectomy was performed. The postoperative recovery was uneventful. DISCUSSION: There are a very small number of reported cases with laparoscopic cholecystectomy for overlooked gallbladder duplication. Preoperative diagnosis holds a major contribution in planning surgery and preventing potential biliary injuries or re-operation if accessory gallbladder has been overlooked during initial surgery. CONCLUSION: Accessory gallbladder is a uncommon congenital anomaly that demands particular consideration. Duplicated gallbladder is associated with increased operative difficulty and risks, including conversion to open cholecystectomy common bile duct injury or second cholecystectomy due to overlooked accessory gallbladder. KEY WORDS: Duplicated gallbladder, Laparoscopic cholecystectomy, Overlooked accessory gallbladder, Reoperation.
