Diagnostic Utility of Mucosal Biopsies Taken During Colonoscopy-Guided Colonic Manometry Catheter Placement.

Objectives: The diagnostic utility of mucosal biopsies taken during colonoscopy-guided colonic manometry catheter placement is unknown. The aims of our study were to determine the frequency and histopathology results of mucosal biopsies during these procedures and to assess whether there were any associations between the histology or gross findings with manometry results.

Methods: We performed a retrospective chart review of children who had a colonic manometry study completed between 2008 and 2020 at a quaternary children's hospital.

Gastrointestinal Symptoms Profile in Pediatric Patients With Gastroparesis Compared to Healthy Controls.

Objectives: The primary objective was to compare the patient-reported gastrointestinal symptoms profiles of pediatric patients with gastroparesis to matched healthy controls using the Pediatric Quality of Life Inventory™ (PedsQL™) Gastrointestinal Symptoms Scales. The secondary objectives were to compare pediatric patients with gastroparesis to pediatric patients with gastroparesis-like symptoms and normal gastric emptying and to compare pediatric patients with gastroparesis-like symptoms and normal gastric emptying to matched healthy controls.

Methods: The PedsQL™ Gastrointestinal Symptoms Scales were completed by 64 pediatric patients with gastroparesis, 59 pediatric patients with gastroparesis-like symptoms and normal gastric emptying, and 200 age, gender, and race/ethnicity matched healthy controls.

Ancestral diversity improves discovery and fine-mapping of genetic loci for anthropometric traits-The Hispanic/Latino Anthropometry Consortium.

Hispanic/Latinos have been underrepresented in genome-wide association studies (GWAS) for anthropometric traits despite their notable anthropometric variability, ancestry proportions, and high burden of growth stunting and overweight/obesity. To address this knowledge gap, we analyzed densely imputed genetic data in a sample of Hispanic/Latino adults to identify and fine-map genetic variants associated with body mass index (BMI), height, and BMI-adjusted waist-to-hip ratio (WHRadjBMI). We conducted a GWAS of 18 studies/consortia as part of the Hispanic/Latino Anthropometry (HISLA) Consortium (stage 1, n = 59,771) and generalized our findings in 9 additional studies (stage 2, n = 10,538).

Overview of Breath Testing in Clinical Practice in North America.

Human breath is an easily, noninvasively obtained substance. It offers insight into metabolism and is used to diagnose disaccharide malabsorption, infection, small bowel bacterial over growth, and transit times. Herein, we discuss the readily available clinical breath tests, how they function, how they are administered and interpreted and some pitfalls in their use.

Getting my child to eat the right amount. Mothers' considerations when deciding how much food to offer their child at a meal.

Feeding young children successfully requires parenting skills, trust that children will eat, and nutrition and child development knowledge to ensure that foods and the amounts offered are developmentally appropriate. Mothers are often responsible for determining how much food is offered to their children; however, the influences on mothers' decisions regarding how much to offer their children--their motivations, goals for feeding and child consumption--have not been investigated. Study aims included gathering qualitative data regarding mothers' decisional processes related to preparing a dinner meal plate for her preschooler.

Portion sizes for children are predicted by parental characteristics and the amounts parents serve themselves.

Background: Children's energy intakes are influenced by the portions they are served. Factors influencing the amounts adults offer children are not well described.

Objective: We assessed whether the amounts that were served to and consumed by children at meals were related to amounts that parents served themselves.

Validation of the PDPAR as an adolescent diary: effect of accelerometer cut points.

Purpose: To evaluate the validity of the Previous Day Physical Activity Recall (PDPAR) as a physical activity diary in adolescents using two accelerometer intensity classifications.

Methods: One hundred eighth graders (47 boys, 53 girls) used the PDPAR as a daily diary and wore MTI accelerometers for four consecutive days. Measured time spent in moderate (> or = 3 METs) and vigorous (> or = 6 METs) activity was based on two published MTI cut-point limits (that of Freedson et al.

Cross-cultural equivalence of feeding beliefs and practices: the psychometric properties of the child feeding questionnaire among Blacks and Hispanics.

Background: Psychometrically sound measures are considered a necessary condition for valid research. This study used structural equation modeling to examine the cross-cultural equivalence of a widely used measure of parental beliefs and practices regarding child feeding, the Child Feeding Questionnaire [Birch L.L.
