Mobile Health technology in pediatric esophagogastroduodenoscopy quality indicators assessment: results from a national program of the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition.

BACKGROUND AND AIMS: Upper endoscopy procedures (UEP, esophagogastroduodenoscopy [EGDS] and retrograde endoscopic retrograde cholangiography [ERCP]) are an established standard of care in pediatric gastroenterology. The Pediatric endoscopy quality improvement network (PEnQuIN) recently published its pediatric-specific endoscopy quality guidelines. This study, initiated by the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP), aims to evaluate the adherence of Italian Pediatric Endoscopy Centers to these established quality standards. METHODS: Conducted between April 2019 and March 2021, this nationwide study utilized a smartphone app-based approach. Data encompassing pediatric endoscopy facilities, patient profiles, endoscopy indications, 17 procedure-related PEnQuIN indicators, and a GHAA-9m patient satisfaction questionnaire were systematically collected. RESULTS: A comprehensive analysis of 3582 procedures from 24 PECs revealed that 2654 (76%) were UEP. The majority of centers (75%) involved more than one operator, with 9 PEC incorporating adult endoscopists, responsible for 5% of UEPs. Overall, adherence to quality standards was good; however, areas of improvement include sub-optimal reporting of sedation details, adherence to disease-specific guidelines, and patient satisfaction questionnaire completeness (56%). The complication rate aligned with literature standards (1%), and patient satisfaction was generally high. A noteworthy observation was a 30% decrease monthly reporting rate and a shift in disease-specific patterns following the COVID-19 outbreak. CONCLUSIONS: Pediatric UEP practices in Italy adhere well to established quality standards. Emphasizing the adoption of disease-specific guidelines is crucial for optimizing resources, enhancing diagnostic accuracy, and minimizing unnecessary procedures. Prioritizing patient satisfaction is important for immediate enhancements in practice as well as for future research endeavors.

Foreign body ingestion in children: Definition of a nomogram to predict surgical or endoscopic intervention.

BACKGROUND AND AIMS: Foreign body ingestion (FBI) in children requires early identification to prevent adverse outcomes and may necessitate endoscopic or surgical intervention. This study aims to develop a nomogram that identifies children who require urgent surgical or endoscopic intervention by using the patient's medical history and clinical parameters collected at admission. METHODS: This study is a retrospective review (01/2015-12/2020) of a multicenter case series of children admitted for FBI. Data from 5864 records from 24 hospitals in Italy were analyzed. Logistic regression models were used to establish the probability of requiring surgical or endoscopic intervention based on patient history and clinical characteristics. The nomogram representing the results from the multivariable model was reported to examine the propensity for surgery/endoscopy. RESULTS: The study identified a significant association between intervention and various factors, including type of foreign body (blunt: reference category, disk battery (odds ratio OR:4.89), food bolus (OR:1.88), magnets (OR:2.61), sharp-pointed (OR:1.65), unknown (OR:1.02)), pre-existing diseases or conditions (OR 3.42), drooling (OR 10.91), dysphagia (OR 5.58), vomiting (OR 3.30), retrosternal pain (OR 5.59), abdominal pain (OR 1.58), hematemesis (OR 2.82), food refusal/poor feeding (OR 2.99), and unexplained crying (OR 2.01). The multivariable regression model showed good calibration and discrimination ability, with an area under the ROC curve of 0.77. CONCLUSIONS: This study developed the first nomogram to predict the probability of the need for surgical or endoscopic intervention in children with FBI, based on the information collected at admission. The nomogram will aid clinicians in identifying children who require early intervention to prevent adverse outcomes.

Effects of bioflavonoids in the management of subclinical varicocele.

BACKGROUND: Subclinical varicocele is a relative rare condition. The aim of this study is to identify the role of bioflavonoids in the management of subclinical varicocele. MATERIALS AND METHODS: We analyzed the medical charts of patients treated for subclinical varicocele with bioflavonoids between 1999 and 2004; inclusion criteria were created before treatment. Short and long-term results after treatment were studied and compared with untreated patients. RESULTS: One hundred and sixty-eight patients with left subclinical varicocele were included in the study. Long-term results showed a possible correlation between use of bioflavonoids and lesser rate of clinical progression to palpable varicocele (11 vs. 31%), higher rate of stable vein reflux (47 vs. 38%) and higher resolution rate (41 vs. 31%) (p > 0.05). Bioflavonoids did not show any protective factor against testicular growth arrest. CONCLUSIONS: Subclinical varicocele should be considered as the starting point of varicocele, and although the use of bioflavonoids in patients with subclinical varicocele could reduce the development of palpable varicocele, it cannot prevent the onset of testicular growth arrest.

Foreign body and caustic ingestions in children: A clinical practice guideline.

Foreign body and caustic ingestions in children are usually the most common clinical challenges for emergency physicians, general pediatricians and pediatric gastroenterologists. Management of these conditions often requires different levels of expertise and competence. Endoscopy is often necessary but there is a high risk of misusing this tool with incorrect timing and indications. The imprecise clinical history frequently leaves clinicians uncertain about timing and nature of the ingestion. Few clinical guidelines regarding management of these ingestions in children have been published, none of which from the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP). An expert panel of Italian endoscopists was convened by the SIGENP Endoscopy Working Group to produce the present article that outlines practical clinical approaches to the pediatric patient with a variety of foreign body and caustic ingestions. The Italian Association of Hospital Gastroenterologists and Endoscopists (AIGO) has also endorsed the project since many adult endoscopists usually manage children with these conditions. Differently from the other published guidelines, the proposed one focuses on the role of the endoscopists (regardless of whether they are adult or pediatric gastroenterologists) in the diagnostic process of children with foreign body and caustic ingestions.

The relationship between body size and depression symptoms in adolescents.

OBJECTIVE: To evaluate the relationship between body size and depressive symptoms, as well as the moderating effects of age, sex, and socioeconomic status (SES), in a sample of young adolescents. STUDY DESIGN: The study group comprised 678 young adolescents (age 11 to 14 years). Body mass index (BMI) z scores were used to estimate body size. Depression symptoms were assessed using the Children's Depression Inventory (CDI). The spline function was used to examine the shape of the relationship between BMI z score and depressive symptoms. RESULTS: In the total sample, CDI scores were lowest for BMI z scores between -1 and -0.5. CDI scores increased progressively for BMI z scores > 0. In boys, CDI scores increased for BMI z scores > 2, whereas in girls, CDI scores increased for BMI z scores > -0.5 and < -1. Age did not have a significant moderating effect. SES had a moderating effect only in boys (P = .011). CONCLUSIONS: The relationship between body size and depressive symptoms in young adolescents is curvilinear and is moderated by sex. Heavier-than-average and underweight girls, as well as obese boys, had the highest depression scores.

Paediatric Home Artificial Nutrition in Italy: Report from 2016 Survey on Behalf of Artificial Nutrition Network of Italian Society for Gastroenterology, Hepatology and Nutrition (SIGENP).

Home Artificial Nutrition (HAN) is a safe and efficacious technique that insures children's reintegration into the family, society and school. Epidemiological data on paediatric HAN in Italy are not available. AIM: to detect the prevalence and incidence of Home Parenteral Nutrition (HPN) and Home Enteral Nutrition (HEN), either via tube or mouth, in Italy in 2016. MATERIALS AND METHODS: a specific form was sent to all registered SIGENP members and investigators of local HAN centres, inviting them to provide the requested centre's data and demographics, underlying diseases and HAN characteristics of the patients. RESULTS: we recorded 3403 Italian patients on HAN aged 0 to 19 years from 22 centres: 2277 HEN, 950 Oral Nutritional Supplements (ONS) and 179 HPN programs. The prevalence of HEN (205 pts/million inhabitants) and HPN (16 pts/million inhabitants) has dramatically increased in Italy in the last 9 years. Neurodisabling conditions were the first indication for HEN by tube or mouth while HPN is mainly requested in digestive disorders. CONCLUSIONS: HAN is a widespread and rapidly growing treatment in Italy, as well as in other European countries. Awareness of its extent and characteristics helps improving HAN service and patients' quality of life.

Lactobacillus paracasei A survives gastrointestinal passage and affects the fecal microbiota of healthy infants.

This study focuses on the potentiality of a putative probiotic strain, Lactobacillus paracasei A, to survive gastrointestinal (GI) passage and modulate the resident microbiota of healthy infants. In a placebo-controlled study, 26 children aged 12-24 months received 100 g/day of either fermented milk containing strain A or pasteurized yogurt for four weeks. Fecal samples were analyzed before starting the administration, after 1, 3 and 4 weeks of consumption and after washout. The fate of strain A was followed by means of a newly developed PCR targeting a strain-specific genomic marker. The composition and dynamics of fecal microbial communities during the study were analyzed by culturing on selective media and by the PCR-denaturing gradient gel electrophoresis (DGGE) technique using universal and group-specific (Lactobacillus and Bifidobacterium) primers. The variation in enzymatic activities in infant feces during probiotic consumption was also analyzed. Strain A survived in fecal samples in most (92%) of the infants examined after 1 week of consumption, and temporarily dominated the intestinal Lactobacillus community. The administration of L. paracasei A led to a significant increment in the Lactobacillus population, while a moderate effect upon the main bacterial groups in the GI ecosystem was observed. Strain A also affected the diversity of the Lactobacillus and Bifidobacterium populations. The fecal bacterial structure of 1 - 2-year-old infants seems to combine neonate and adult-like features. The microbiota of these subjects promptly responded to probiotic consumption, later restoring the endogenous equilibrium.

Ghrelin, insulin sensitivity and postprandial glucose disposal in overweight and obese children.

OBJECTIVE: To explore the changes of ghrelin circulating levels induced by a mixed meal and their relationship with postprandial substrate oxidation rates in overweight and obese children with different levels of insulin sensitivity. METHODS: A group of ten boys (age 9-12 years) with different levels of overweight (standard deviation score of body mass index: 1.6-3.2) was recruited. Body composition was measured by dual-energy X-ray absorptiometry. Insulin sensitivity was assessed by a frequently sampled i.v. glucose tolerance test. Pre-prandial and postprandial (3 h) substrate oxidation was measured by indirect calorimetry. The energy content of the test meal (16% protein, 36% carbohydrate and 48% fat) was 40% of pre-prandial energy expenditure (kJ/day). RESULTS: Pre-prandial serum concentration of total ghrelin was 701.4+/-66.9 pg/ml (S.E.M.). The test meal induced a rapid decrease in ghrelin levels and maximal decrease was 27.3+/-2.7% below baseline. Meal intake induced a progressive increase of the carbohydrate oxidation rate for 45 min after food ingestion, followed by a slow decrease without returning to pre-prandial values. Postprandial cumulative carbohydrate oxidation was 16.9+/-0.8 g/3 h. Insulin sensitivity and postprandial maximal decrease of ghrelin concentration showed a significant correlation (r = 0.803, P < 0.01). Moreover, the postprandial carbohydrate oxidation rate correlated with the area under the curve for both insulin (r = 0.673, P < 0.03) and ghrelin (r = -0.661, P < 0.04). CONCLUSIONS: A relevant association between postprandial insulin-mediated glucose metabolism and ghrelin secretion in children with different levels of overweight was found. It is possible that the maintenance of an adequate level of insulin sensitivity and glucose oxidation may affect appetite regulation by favoring a more efficient postprandial ghrelin reduction.

The relationship between body mass index and body size dissatisfaction in young adolescents: spline function analysis.

This study assessed how body size dissatisfaction (BSD) varies in relationship to specific body mass index (BMI) values in a sample of preadolescents. A novel statistical approach based on spline function, suitable to assess in detail how two variables are related, was used. The study was conducted between December 2004 and March 2005. Students (aged 11 to 14 years) from seven selected secondary schools in Verona, Italy, were invited to participate. The final study group included 678 subjects. BSD was assessed using the Body Image Assessment Procedure. BMI values were expressed as z scores. It was found that, in the total sample, slightly underweight subjects (BMI z scores=-0.5) had no BSD. BSD progressively increased (current body size > ideal body size) for BMI z scores >-0.5 and became negative (ideal body size > current body size) for BMI z scores <-0.5. In boys, average weight subjects had no BSD. BSD progressively increased for BMI z scores >0 and became negative for BMI z scores <0. In girls, moderately underweight subjects (BMI z scores=-1) had no BSD. BSD progressively increased for BMI z scores >-1 and became negative for BMI z scores <-1. Although sex significantly moderated the relationship between BMI and BSD (P<0.001), socioeconomic status did not (P=0.459). Because average weight and slightly underweight young girls desired a thinner body, our study suggests that these subgroups should receive particular attention in public health programs as well as in dietetics clinical practice.
