Intestinal microbiota disruption is associated with acute gastrointestinal (GI) Graft-versus-Host Disease (GvHD) and poor outcome after allogeneic stem cell transplantation (ASCT). Here, in a retrospective analysis of 200 patients undergoing ASCT at the Regensburg University Medical Center, we assessed the relative expression of Paneth cell antimicrobial peptides (AMPs), Human Defensins (HD) 5 ...

BACKGROUND The clinical manifestations of celiac disease (CD) have changed in the past decades. There are currently little data describing the initial clinical manifestations of CD in children in Iran. This study describes the initial presentation of children with suspected CD from a geographically defined region in Iran. METHOD Medical records of children seen in 2007 - 2015 from Sistan and ...

Gastrointestinal (GI) bleeding in pediatric patients has several causes. Vascular malformation of the small bowel is a rare disease leading to pediatric GI bleeding. To our knowledge, few reports describe ultrasound and computed tomography findings of venous malformations involving the small bowel. We present a case of long-segmental and circumferential vascular malformation that led to GI blee...

Gastrointestinal (GI) symptoms are being increasingly recognized as early, common, and severe features of Parkinson's disease (PD), and they are important determinants of quality of life and disability throughout the disease course. In addition, the concept that GI symptoms could represent "pre-motor" PD has been hotly debated and has recently become a driving force for investigations into the ...

We formulate a control problem for GI/GI/N+GI queue, whose objective is to trade off the long-run average operational costs with server utilization costs. To solve problem, we consider an asymptotic regime in which arrival rate and number of servers grow large. The solution associated fluid motivates that non-idling service disciplines are not general optimal, unless some arrivals turned away. ...

Introduction: Periodontal disease, an inflamma- tory and infectious disease in adults and anemia associated with chronic infection, is one of the most common types of anemia. Considering the similarity of pathogens causing periodontal dis‌ease and anemia, this study aims to investigate the correlation between hematologic para‌meters associated with anemia and modera‌te chronic periodontitis. &...

Gender-related physiological variations in gastrointestinal (GI) symptomatology have been observed in women of reproductive age. Many women experience cyclical changes in GI symptomatology during their menstrual cycle, particularly alteration in their bowel habits. Physiological studies of healthy women during the menstrual cycle showed a prolonged GI transit time during the luteal phase, eithe...

The glycemic index (GI) refers to impact of the ingestion of carbohydrate-containing foods on blood sugar concentrations. High-GI foods increase blood glucose levels more and for a longer time, than those with low GIs. It appears that those who adopt a low-GI diet have a reduced risk of heart disease, type 2 diabetes mellitus, and obesity. Carbohydrate-containing foods on a low-GI diet include ...

Inflammatory bowel disease (IBD) is a chronic recurrent condition whose etiology is unknown, and it includes ulcerative colitis, Crohn's disease, and microscopic colitis. These three diseases differ in clinical manifestations, courses, and prognoses. IBD reduces the patients' quality of life and is an economic burden to both the patients and society. Interactions between the gastrointestinal (G...
