Abstract
The positive impact of probiotic strains on human health has become more evident than ever before. Often delivered through food, dietary products, supplements, and drugs, different legislations for safety and efficacy issues have been prepared. Furthermore, regulatory agencies have addressed various approaches toward these products, whether they authorize claims mentioning a disease's diagnosis, prevention, or treatment. Due to the diversity of bacteria and yeast strains, strict approaches have been designed to assess for side effects and post-market surveillance. One of the most essential delivery systems of probiotics is within food, due to the great beneficial health effects of this system compared to pharmaceutical products and also due to the increasing importance of food and nutrition. Modern lifestyle or various diseases lead to an imbalance of the intestinal flora. Nonetheless, as the amount of probiotic use needs accurate calculations, different factors should also be taken into consideration. One of the novelties of this review is the presentation of the beneficial effects of the administration of probiotics as a potential adjuvant therapy in COVID-19. Thus, this paper provides an integrative overview of different aspects of probiotics, from human health care applications to safety, quality, and control.

An expanding spectrum of complications in isolated methylmalonic aciduria.
Forny, P, Grunewald, S
Journal of mother and child. 2020;(2):9-13
Abstract
Isolated methylmalonic acidurias represent a heterogeneous genetic group of inborn errors of propionate metabolism with the common biochemical hallmark of elevated methylmalonic acid present in tissues and body fluids. It was first described in the 1960s and over the years better understanding of the disease and its presentation, earlier diagnosis, and most importantly advances in treatment have resulted in extended survival of patients. With that an expanding spectrum of complications is emerging which requires attention and regular monitoring to facilitate early intervention and reduce disease burden.

Nutrition and gastroenterological support in end of life care.
Schütte, K, Middelberg-Bisping, K, Schulz, C
Best practice & research. Clinical gastroenterology. 2020;:101692
Abstract
Malnutrition and the broad spectrum of cancer cachexia frequently occur in patients with malignant disease of all tumour stages and impact on survival and quality of life of patients. Structured screening for the risk of malnutrition with validated tools and nutritional assessment are the prerequisite for adequate nutritional support in cancer patients. In patients receiving tumour directed therapy, the patients diet should meet the requirements to give optimal support, while later on comfort feeding is part of symptom focused palliation. The basis of nutritional support in a malnourished patient is nutritional counselling, and nutritional support can be offered within a step-up approach meeting the patient's needs. A combination of nutritional support with interventions targeting metabolic changes and physical exercise is suggested to treat cancer cachexia.

Abstract
Gastrointestinal symptoms are common findings in children with SARS-CoV-2 infection. Diarrhea and vomiting have been reported in about 8%-9% of cases, reaching more than 20% in some studies. Children with gastrointestinal involvement appear to be younger than those without, but the severity of the disease seems to be similar between the two groups of subjects. Fecal shedding in children has been reported in 20%-30% of children and has been observed in both those with and those without overt gastrointestinal involvement. Moreover, prolonged fecal elimination, lasting several days after negativization of real-time polymerase chain reaction assay on respiratory swabs, has been reported with variable frequency in children with SARS-CoV-2 infection. These observations raise the question regarding the possibility of oral-fecal transmission and the possible role of children in spreading the infection, particularly when they appear asymptomatic or with gastrointestinal symptoms but with no respiratory involvement, as well as during their convalescent phase.

Abstract
Contrast-enhanced ultrasonography (US) has become an important supplementary tool in many clinical applications in children. Contrast-enhanced voiding urosonography and intravenous US contrast agents have proved useful in routine clinical practice. Other applications of intracavitary contrast-enhanced US, particularly in children, have not been widely investigated but could serve as a practical and radiation-free problem-solver in several clinical settings. Intracavitary contrast-enhanced US is a real-time imaging modality similar to fluoroscopy with iodinated contrast agent. The US contrast agent solution is administered into physiological or non-physiological body cavities. There is no definitive list of established indications for intracavitary US contrast agent application. However, intracavitary contrast-enhanced US can be used for many clinical applications. It offers excellent real-time spatial resolution and allows for a more accurate delineation of the cavity anatomy, including the internal architecture of complex collections and possible communications within the cavity or with the surrounding structures through fistulous tracts. It can provide valuable information related to the insertion of catheters and tubes, and identify related complications such as confirming the position and patency of a catheter and identifying causes for drainage dysfunction or leakage. Patency of the ureter and biliary ducts can be evaluated, too. US contrast agent solution can be administered orally or a via nasogastric tube, or as an enema to evaluate the gastrointestinal tract. In this review we present potential clinical applications and procedural and dose recommendations regarding intracavitary contrast-enhanced ultrasonography.

[Enkephalinases as a new pharmacological target in the treatment of gastrointestinal tract disorders].
Twardowska, A, Fichna, J, Binienda, A
Postepy biochemii. 2020;(3):263-269
Abstract
Enkephalinases, which belong to the family of zinc metalloproteases play a crucial role in modulation of the endogenous opioid system (EOS) activity. Enkephalinase inhibitors (EI) allow obtaining therapeutic concentrations of selected endogenous peptides. One of the first EIs, racecadotril possesses antidiarrheal properties. Moreover, there is evidence that racecadotril presents fewer adverse events compared to other medications used for the treatment of diarrhea, such as loperamide. Lower potency for developing serious adverse events may be the key to choosing EIs as the preferred therapy in patients with chronic diseases. Additionally, EOS is involved in pain modulation, hence EIs might also be used as potential medications in treatment of pain. This review discusses the use of EIs in the treatment of gastrointestinal diseases, including irritable bowel syndrome and inflammatory bowel disease.

Probiotics' efficacy in paediatric diseases: which is the evidence? A critical review on behalf of the Italian Society of Pediatrics.
Martinelli, M, Banderali, G, Bobbio, M, Civardi, E, Chiara, A, D'Elios, S, Lo Vecchio, A, Olivero, M, Peroni, D, Romano, C, et al
Italian journal of pediatrics. 2020;(1):104
Abstract
During the last decade several paediatric studies have been published with different possible indications for probiotics, leading to a global increase of probiotics' market. Nevertheless, different study designs, multiple single/combined strains and small sample size still leave many uncertainties regarding their efficacy. In addition, different regulatory and quality control issues make still very difficult the interpretation of the clinical data. The objective of this review is to critically summarise the current evidence on probiotics' efficacy and safety on a different number of pathologies, including necrotizing enterocolitis, acute infectious diarrhoea, allergic diseases and functional gastrointestinal disorders in order to guide paediatric healthcare professionals on using evidence-based probiotics' strains. To identify relevant data, literature searches were performed including Medline-PubMed, the Cochrane Library and EMBASE databases. Considering probiotics strain-specific effects, the main focus was on individual probiotic strains and not on probiotics in general.

Gastrointestinal manifestations and nutritional therapy during COVID-19 pandemic: a practical guide for pediatricians.
Oba, J, Carvalho, WB, Silva, CA, Delgado, AF
Einstein (Sao Paulo, Brazil). 2020;:eRW5774
Abstract
Coronavirus disease 2019 (COVID-19) is a disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which has spread globally in pandemic proportions. Accumulative evidence suggests SARS-CoV-2 can be transmitted through the digestive system, the so-called fecal-oral route of transmission, and may induce several gastrointestinal manifestations. MEDLINE® and Embase databases were extensively searched for major clinical manifestations of gastrointestinal involvement in children and adolescents with COVID-19 reported in medical literature, and for nutritional therapy-related data. Findings and recommendations were pragmatically described to facilitate overall pediatric approach. A total of 196 studies addressing gastrointestinal or nutritional aspects associated with the global COVID-19 pandemic were found. Of these, only 17 focused specifically on pediatric patients with regard to aforementioned gastrointestinal or nutritional aspects. Most articles were descriptive and six addressed guidelines, established protocols, or expert opinions. Children and adolescents with gastrointestinal symptoms, such as nausea, vomiting and diarrhea, should be seriously suspected of COVID-19. Gastrointestinal signs and symptoms may occur in 3% to 79% of children, adolescents and adults with COVID-19, and are more common in severe cases. These include diarrhea (2% to 50%), anorexia (40% to 50%), vomiting (4% to 67%), nausea (1% to 30%), abdominal pain (2% to 6%) and gastrointestinal bleeding (4% to 14%). Patients with inflammatory bowel disease or chronic liver disease are not at greater risk of infection by SARS-CoV-2 relative to the general population. Nutritional support plays an important role in treatment of pediatric patients, particularly those with severe or critical forms of the disease. The digestive system may be a potential route of COVID-19 transmission. Further research is needed to determine whether the fecal-oral route may be involved in viral spread. Nutritional therapy is vital to prevent malnutrition and sarcopenia in severe cases.

Probiotics and Gut Health in Athletes.
Miles, MP
Current nutrition reports. 2020;(3):129-136
Abstract
PURPOSE OF REVIEW To provide a focused analysis of the challenges to gut health in athletes and examine recent research aimed at determining the impact of probiotics on preventing gastrointestinal (GI) symptoms and loss of barrier function in athletes. RECENT FINDINGS Frequency and severity of GI symptoms during training or competition were reduced by approximately one-third in studies demonstrating efficacy. Improvement of GI symptoms with probiotic supplementation was measured in both single-strain Lactobacillus and multi-strain Lactobacillus and Bifidobacterim probiotics, while improvement in gut barrier function was only measured for multi-strain probiotics. Likelihood of efficacy increased with duration of supplementation. The greatest efficacy for reducing GI symptom frequency and severity, as well as improving or preserving gut barrier function during exercise training and competition, appears to be for multi-strain Lactobacillus and Bifidobacterium probiotic cocktails supplemented for at least 11 weeks.

Gastrointestinal Disorders and the Nervous System.
White, H
Continuum (Minneapolis, Minn.). 2020;(3):577-590
Abstract
PURPOSE OF REVIEW This article describes the neurologic sequelae of various nutritional micronutrient deficiencies, celiac disease, inflammatory bowel disease, and liver disease. Where relevant, appropriate treatments for these conditions are also discussed. The developing field of the microbiome and nervous system interaction is also outlined. RECENT FINDINGS Pathology in the gastrointestinal system can affect the nervous system when it causes micronutrient deficiency, when immune responses created by the gastrointestinal system affect the nervous system, when toxins caused by gastrointestinal organ failure harm the nervous system, and when treatments aimed at a gastrointestinal medical condition cause damage to the nervous system as a side effect. SUMMARY This article addresses familiar concepts and new developments in the treatment and understanding of diseases that affect the gut and nervous system simultaneously.
