Fecal microbiota transplantation (FMT) is being studied and utilized for various medical conditions including Clostridium difficile colitis, inflammatory bowel diseases (IBD), obesity, myasthenia gravis, and so on. Yet, FMT donation, whether from an individual or a stool bank, can be challenging given the numerous requirements and donor costs. Furthermore, data outcomes on recipients of FMT regarding donor's health co-morbidities, age, and weight are limited but emerging. The purpose of this review is to evaluate cost, safety, and accessibility in FMT donation.

Fecal microbiota transplantation is becoming a growing therapy for a variety of indications, including recurrent or refractory Clostridium difficile infection (CDI), as well as many other gastrointestinal and extra-intestinal diseases. In fact, fecal microbiota transplantation is now strongly recommended as the treatment of choice for multiple recurrences of CDI, given its strong efficacy and a favorable short-term side effect profile. As the application of this therapy expands, awareness of its adverse events has also developed. The purpose of this review is to bring to light the side effects and complications associated with fecal microbiota transplantation, with an emphasis on findings from recently published studies.

Background and Aims The debate between moderate sedation versus deep sedation for index average-risk screening colonoscopies is well known to gastroenterologists. Ensuring the best of all metrics to perform quality colonoscopies for colon cancer prevention is paramount for both patients and physicians alike, because colon cancer remains the leading cause of cancer death and is the most-used screening tool in the United States. The aim of this study was to determine if moderate sedation versus deep sedation affects outcomes of adenoma detection rate (ADR) or polyp detection rate (PDR) in index, average-risk colonoscopies for colon cancer screening. Methods A retrospective, single, tertiary care outpatient center study of 585 healthy average-risk patients who underwent index screening colonoscopy between June 1, 2015 to December 31, 2015 (moderate sedation only) and June 1, 2016,to December 31, 2016 (deep sedation only) was performed after Institutional Review Board approval. Demographic data and polyp details were collected to determine ADR and PDR. Patients who were not average risk were excluded from the study. Results A total of 585 index average-risk screening colonoscopies were included in this study with 57.7% moderate sedation and 42.2% deep sedation. Neither ADR nor PDR was significantly different between the 2 groups (44.1% vs 38.5% [P = .18] and 71.9% vs 67.6% [P = .27], respectively). Conclusions In index average-risk screening colonoscopies, deep sedation appears to have no benefit compared with moderate sedation for ADR and PDR.

Background: Probiotics can be viewed as biological agents that modify the intestinal microbiota and certain cytokine profiles, which can lead to an improvement in certain gastrointestinal diseases, including diarrhea, inflammatory bowel disease, and liver disease. Discussion: Consumption of probiotics in their various forms, including yogurt, functional foods, and dietary supplements, is frequently encountered worldwide. Often, however, the correct prescription of these agents is dampened due to a lack of knowledge of the scientific evidence and the different presentations and microbial compositions of the currently available probiotic options. Here, we provide an up-to-date review of the evidence of probiotics in the prevention and treatment of various gastrointestinal diseases. Objective: Consumption of probiotics in their various forms, including yogurt, functional foods, and dietary supplements, is frequently encountered worldwide. Often, however, the correct prescription of these agents is dampened due to a lack of knowledge of the scientific evidence and the different presentations and microbial compositions of the currently available probiotic options. Methods/Results: Here, we provide an up-to-date review of the evidence of probiotics in the prevention and treatment of various gastrointestinal diseases. Conclusion: While not efficacious in every disease process studied, probiotics have demonstrated some benefit in several specific gastrointestinal and liver diseases.

Background Sarcopenia, i.e., muscle loss is now a well-recognized complication of cirrhosis and in cases of non-alcoholic fatty liver disease can contribute to accelerate liver fibrosis leading to cirrhosis. Hence, it is imperative to study interventions which targets to improve sarcopenia in cirrhosis. Aim To examine the relationship between interventions such nutritional supplementation, exercise, combined life style intervention, testosterone replacement and trans jugular intrahepatic portosystemic shunt (TIPS) to improve muscle mass in cirrhosis. Methods We search PubMed, EMBASE and Cochrane between June-August 2018, without a limiting period and the types of articles (RCTs, clinical trial, comparative study) in adult patients with sarcopenia and cirrhosis. The primary outcome of interest was improvement in muscle mass, strength and physical function interventions mentioned above. In the screening process, 154 full text articles were included in the review and 129 studies were excluded. Results We identified 24 studies that met review inclusion criteria. The studies were diverse in terms of the design, setting, interventions, and outcome measurements. We performed only qualitative synthesis of evidence due to heterogeneity amongst studies. Risk of bias was medium in most of the included studies and low quality of evidence showed improvement in the muscle mass, strength and physical function following aerobic exercise. 60% of the included studies on the nutritional intervention, 100% of the studies on testosterone replacement in hypogonadal men and trans-jugular portosystemic shunt were proved to be effective in improving sarcopenia in cirrhosis. Conclusion Although the quality of evidence is low, the findings of our systematic review suggest improvement in the sarcopenia in cirrhosis with exercise, nutritional interventions, hormonal and TIPS interventions. High quality randomized controlled trials needed to further strengthen these findings.

Much research has been performed over the last decade on stem cell therapy as treatment for patients with inflammatory bowel disease. Hematopoietic and mesenchymal stem cells, both allogeneic (from someone else) and autologous (from own patient), have been studied with safe and efficacious results in the majority of patients treated for luminal, perianal, and/or fistulizing disease. Here in this review, we highlight all human trials that have been conducted utilizing stem cell therapy treatment in patients with inflammatory bowel disease.

Patients with fistulizing inflammatory bowel disease are traditionally difficult to treat. This patient population often experiences delayed or insufficient healing of fistulas using current standard regimens including antibiotics, immunomodulators, anti-tumor necrosis factor-α drug, placement of setons, and surgical repair. Several studies over the last ten to fifteen years have been conducted using stem cell therapies with promising results in this patient population. These studies show stem cell therapy in fistulizing disease to be successful in healing between 60%-88% compared to currently 50% with infliximab. Moreover, remission was seen 24 wk to 52 wk in these studies. Further research with a multi-approach treatment using medications, stem cell therapy, and surgical interventions will likely be the future of this innovative treatment approach.

Those patients with perianal Crohn's disease or ulcerative colitis experience a difficult to treat disease process with a delayed state and often inability to heal despite current therapies. The approaches currently used to treat these patients with corticosteroids, antibiotics, immunomodulators, anti-tumor necrosis factor-α drug, and surgical repair are limited in their healing ability. This review presents all current literature since emergence in the early 2000s of stem cell therapy for patients with perianal inflammatory bowel disease and analyzes the efficacy, outcomes and safety within these studies.

Background and objective Fat accumulation in the pancreas has remained a relatively unknown disease since it was initially described in 1926. However, it has gained increasing attention in the past two decades with the emergence of the obesity epidemic. Pancreatic steatosis is a general term used for fat accumulation in the pancreas. It is further classified into fatty replacement, fatty infiltration, lipomatous pseudo-hypertrophy, non-alcoholic fatty pancreas disease (NAFPD) and non-alcoholic fatty steatopancreatitis (NASP). NAFPD is defined as obesity-associated accumulation of fat in the pancreas without significant alcohol consumption. Data on the prevalence of NAFPD are limited due to a lack of standardized screening tests. Methods MEDLINE/PubMed was searched to find relevant studies and abstracts on pancreatic steatosis. Results Pancreatic fat can be quantified by various imaging techniques including ultrasonography, computed tomography, magnetic resonance imaging and magnetic resonance spectroscopy. The pathophysiology of NAFPD has not been completely understood. Chronic exposure of β-cells to hyperglycemia and higher levels of free fatty acids results in increased intracellular triglyceride accumulation, which ultimately causes reduced insulin secretion, insulin resistance, cell apoptosis and subsequent fatty replacement. This vicious cycle likely is a determining factor in the development of diabetes mellitus and metabolic syndrome. There is no approved pharmacologic therapy for NAFPD. Caloric restriction might have a role in normalization of β-cell function by reducing pancreatic fat content. Troglitazone (blend of telmisartan and sitagliptin) has demonstrated effectiveness in animal models but is still in experimental stages. Conclusion The cause and effect relationship between the metabolic syndrome and NAFPD has not yet been established. Further studies are required to study the effect of NAFPD on glucose hemostasis.
