Gut Microbiota and NAFLD Development
NAFLD, the most common liver disorder in the Western world, is characterized by intrahepatic lipid accumulation; is highly prevalent in the aging population; and is closely associated with obesity, insulin resistance, hypertension, and dyslipidemia.

Effects of GLP-1 Receptor Agonists on NAFLD
Non-alcoholic fatty liver disease (NAFLD) is the most frequent liver disease, affecting up to 70% of patients with diabetes. There are no specific drugs available for its treatment. Beyond their anti-hyperglycemic effect and the surprising role of cardio- and nephroprotection, GLP-1 receptor agonists (GLP-1 RAs) have shown a significant impact on body weight and clinical, biochemical and histological markers of fatty liver and fibrosis in patients with NAFLD. Therefore, GLP-1 RAs could be a weapon for the treatment of both diabetes mellitus and NAFLD.

Methods of Measuring Pancreatic Cystic Lesion Size
The incidence of pancreatic cystic lesions (PCLs) has been rising due to improvements in imaging. Of these, intraductal papillary mucinous neoplasms (IPMNs) are the most common and are thought to contribute to almost 20% of pancreatic adenocarcinomas. All major society guidelines for the management of IPMNs use size defined by maximum diameter as the primary determinant of whether surveillance or surgical resection is recommended. However, there is no consensus on how these measurements should be obtained or whether a single imaging modality is superior. Furthermore, the largest diameter may fail to capture the complexity of PCLs, as most are not perfectly spherical.

The Molecular Mechanisms of Lipopolysaccharides Tolerance
Lipopolysaccharides (LPSs) are complex molecules found in the outer membrane of Gram-negative bacteria, which are composed of three main regions: lipid A, core oligosaccharide, and O antigen.

Diagnosis of Cytomegalovirus Infection
Cytomegalovirus (CMV) infection is still a matter of concern in Inflammatory Bowel Diseases (IBD) patients, especially regarding the disease’s relapse management. Why IBD patients, particularly those affected by ulcerative colitis, are more susceptible to CMV reactivation is not totally explained, although a weakened immune system could be the reason.

Molecular Mechanisms of Antiviral Protease Inhibitor-induced Liver Injury
Antiviral protease inhibitors (PIs) are peptidomimetic molecules that block the active catalytic center of viral proteases and, thereby, prevent the cleavage of viral polyprotein precursors into maturation. They continue to be a key class of antiviral drugs that can be used either as boosters for other classes of antivirals or as major components of current regimens in therapies for the treatment of infections with human immunodeficiency virus (HIV) and/or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, sustained/lifelong treatment with the drugs or drugs combined with other substance(s) often leads to severe hepatic side effects such as lipid abnormalities, insulin resistance, and steatohepatitis. Molecular mechanisms underlying the PI-induced liver injury and potential therapeutic/pharmaceutical solutions are systemically reviewed here.

Antioxidant and Anti-Inflammatory Phytochemicals for Inflammatory Bowel Disease
Inflammatory bowel disease (IBD) mainly comprises Crohn’s disease (CD) and ulcerative colitis (UC) and is a group of chronic relapsing disorders characterized by inflammation of the gastrointestinal tract with variable phenotypic expression. Multiple factors have been implicated in the etiology of IBD, including environmental, genetic, microbiological and immunological interactions. However, the exact reasons remain unclear, although substantial progress in elucidating the complexity of IBD manifestation has been made in the past decades. There is clinical overlap of symptoms of CD and UC, including bloody or watery diarrhea, recurrent abdominal pain, tenesmus as well as non-specific systemic symptoms such as fatigue, fever and weight loss. CD can affect various parts of the intestine, i.e., both small and large intestine, while UC is known to affect only the colon. IBD usually follows a lifelong pattern of remissions and flare-ups that impacts the quality of life of patients. The inflammation of the gastrointestinal tract during flare-ups is mediated by neutrophils that release cytokines, enzymes and reactive oxygen species (ROS) leading to damage and even ulceration of the mucosa.

Management of Pediatric Feeding Disorder
Pediatric feeding disorder (PFD) is defined as impaired oral intake that is not age appropriate and is associated with at least one dysfunctional domain: medical; nutritional; feeding skills; and psychosocial  Feeding difficulties take time to resolve and are best managed in progressive phases. A series of short-term goals are typically developed that can lead to complex interdisciplinary coordination of care. Using a stepwise treatment approach to PFD is important because, even though feeding problems are relatively common—occurring in up to 45% of children in the general population—the condition is severe enough to warrant intensive intervention in about 10%. A stepwise approach ensures that feeding problems are not overlooked or treated inappropriately.

Photodynamic, Photothermal and Photoimmune Therapy in Hepatocellular Carcinoma
Liver cancer is a malignancy that includes the structure of the liver and intrahepatic bile ducts and is classified as follows: hepatocellular carcinoma, cholangiocarcinoma, hepatic angiosarcoma (hemangiosarcoma), hepatoblastoma, and fibrolamellar carcinoma. Hepatocellular carcinoma (HCC), known also as hepatoma, is the most common type of primary liver neoplasm. HCC is known today as a major malignant disease with high morbidity and mortality, which seriously threatens the health and life span of patients. Conventional cancer therapies comprise surgical procedures, radiation therapy and chemotherapy, which may be efficient but have significant adverse effects. Newer, more prominent cancer-targeted action plans, such as the phototherapy methods including photodynamic therapy (PDT), photothermal therapy (PTT), and photoimmunotherapy (PIT), have sparked excitement and hope as synergistic multimodal cancer therapies, incorporating nanomedicine to overcome the biological barriers and to help treat cancer patients.

Non-Coding RNAs in Hepatocellular Carcinoma Progression
Hepatocellular carcinoma (HCC) is a predominant malignancy with increasing incidences and mortalities worldwide. In Western countries, the progressive affirmation of Non-alcoholic Fatty Liver Disease (NAFLD) as the main chronic liver disorder in which HCC occurrence is appreciable even in non-cirrhotic stages, constitutes a real health emergency. In light of this, a further comprehension of molecular pathways supporting HCC onset and progression represents a current research challenge to achieve more tailored prognostic models and appropriate therapeutic approaches. RNA non-coding transcripts (ncRNAs) are involved in the regulation of several cancer-related processes, including HCC. When dysregulated, these molecules, conventionally classified as “small ncRNAs” (sncRNAs) and “long ncRNAs” (lncRNAs) have been reported to markedly influence HCC-related progression mechanisms.
