The incidence both of diabetes, particularly type 2 (T2DM), and cancer is increasing worldwide, making these diseases growing global health problem along with increasing healthcare expenditures. The current therapeutic approach for the treatment of these multifactorial diseases is far from satisfactory. Therefore, there is still considerable interest in searching new therapeutic strategies with the use of both natural and synthetic compounds exhibiting higher efficiency and lower toxicity compared to medicines used currently in clinical practice...

PURPOSE OF REVIEW: Most of small tumours in gastrointestinal tract are easily removed by endoscopic mucosal resection (EMR). However, EMR are sometimes not reliable to ensure the complete resection for large tumours. Although endoscopic submucosal dissection (ESD) was developed, it had a higher risk for complications such as perforation and bleeding. The techniques and clinical outcomes of EMR and ESD are reviewed. RECENT FINDINGS: ESD is more effective for early gastric and oesophageal cancer with higher en-bloc resection rate and lower local recurrence in comparison to EMR...

INTRODUCTION: Plasmablastic lymphoma (PBL) is a rare lymphoma associated with immunosuppression. It is strongly associated with immunosuppression (human immunodeficiency virus [HIV]) and often occurs within the oral cavity. PBL is also seen in patients receiving immunosuppressive therapy; however, despite its predisposition for the immunocompromised patients, PBL has been diagnosed in immunocompetent patients. AIM: This study aims to prognostic factors and outcome of PBL in immunocompromised and in immunocompetent patients...

Foxp3+ CD4+ Regulatory T cells (Tregs) are a subset of immune cells that function to regulate tissue inflammation. Skin is one of the largest organs and is home to a large proportion of the body's Tregs. However, relative to other tissues (such as the spleen and gastrointestinal tract) the function of Tregs in skin is less well defined. Here, we review our understanding of how Tregs migrate to skin and the cellular and molecular pathways required for their maintenance in this tissue. In addition, we outline what is known about the specialized functions of Tregs in skin...

Pituitary adenylate cyclase activating polypeptide (PACAP) is an endogenous neuropeptide having a widespread distribution both in the nervous system and peripheral organs including the gastrointestinal tract. It has been shown to exert actions on intestinal functions, mainly affecting glandular secretion and motility. PACAP has several different effects on cell survival depending on the cell type and the applied stimulus. Its influences on small intestinal epithelial cells are not yet elucidated, therefore the aim of the present study was to investigate the effects of PACAP on intestinal epithelial cells having high turnover (INT 407) against different harmful stimuli, such as oxidative stress, in vitro hypoxia and gamma radiation...

BACKGROUND: The neutropenic diet (ND) is prescribed to avoid introduction of bacteria into a host's gastrointestinal tract and reduce infection. Due to a lack of evidence to support the ND, there continues to be debate among pediatric oncologists regarding its usefulness. This prospective randomized controlled trial evaluated the difference in neutropenic infection rates in pediatric oncology patients randomized to Food and Drug Administration approved food safety guidelines (FSGs) versus the ND plus FSGs during one cycle of chemotherapy...

BACKGROUND: Radiochemotherapy in cervical cancer was implemented to clinical practice based on five randomized clinical trials, published at the end of 20th century, which showed improvement in total and symptomless survivals by about 10 to 18 %. The increase of therapeutic index of such treatment can take place only at the advantage of the efficiency over the increase of its toxicity. Thus, it is necessary to monitor treatment reaction during radiochemotherapy. OBJECTIVES: The aim of this study is to assess the acute post-radiation reaction during radiochemotherapy for cervical cancer and the analysis of the reasons of the unplanned course of combined treatment...

An accurate staging is necessary to select the best treatment and evaluate prognosis in oncology. Staging usually begins with noninvasive imaging such as computed tomography, magnetic resonance imaging or positron emission tomography. In the absence of distant metastases, endoscopic ultrasound plays an important role in the diagnosis and staging of gastrointestinal tumors, being the most accurate modality for local-regional staging. Its use for tumor and nodal involvement in pre-surgical evaluation has proven to reduce unnecessary surgeries...

Agents that modulate immune checkpoint proteins, such as cytotoxic T-lymphocyte antigen-4 (CTLA-4) and programmed death receptor-1 (PD-1), have become a mainstay in cancer treatment. The clinical benefit afforded by immune checkpoint inhibitors can be accompanied by immune-related adverse events (irAE) that affect the skin, gastrointestinal tract, liver, and endocrine system. The types of irAEs associated with immune checkpoint inhibitors are generally consistent across tumor types. Immune-related endocrine events can affect the pituitary, thyroid, and adrenal glands, as well as other downstream target organs...

Ionizing radiation (IR) is one of the most widely used treatments for cancer. However, acute damage to the gastrointestinal tract or gastrointestinal acute radiation syndrome (GI-ARS) is a major dose-limiting side effect, and the mechanisms that underlie this remain unclear. Here we use mouse models to explore the relative roles of DNA repair, apoptosis, and cell cycle arrest in radiation response. IR induces DNA double strand breaks and DNA-PK mutant Prkdc(scid/scid) mice are sensitive to GI-ARS due to an inability to repair these breaks...

Crohn's disease (CD) is a chronic relapsing and remitting inflammatory disease of the gastrointestinal tract. CD is rare in Taiwan and other Asian countries, but its prevalence and incidence have been steadily increasing. A steering committee was established by the Taiwan Society of Inflammatory Bowel Disease to formulate statements on the diagnosis and management of CD taking into account currently available evidence and the expert opinion of the committee. Thorough clinical, endoscopic, and histological assessments are required for accurate diagnosis of CD...

Extracellular vesicle (EV) production is a universal feature of metazoan cells as well as prokaryotes (bMVs - bacterial microvesicls). They are small vesicles with phospholipid membrane carrying proteins, DNA and different classes of RNAs and are heavily involved in intercellular communication acting as vectors of information to target cells. For the last decade, the interest in EV research has exponentially increased though thorough studies of their roles in various pathologies that was not previously possible due to technical limitations...

Henoch-Schönlein purpura is the most common childhood vasculitis, but may also affect adults. This article reviews the literature since 2011 on advances in diagnosis, clinical disease manifestations, pathophysiology and treatment of Henoch-Schönlein purpura. The clinical manifestations are thought to arise from IgA depositions in blood vessel walls in the affected organs, mostly skin, gastrointestinal tract, joints and kidneys. Corticosteroids may be effective in rapid resolution of renal manifestations and treating joint and abdominal pain, but they are not proven effective for treating organ manifestations and complications, such as glomerulonephritis, bowel infarction or intussusception...
