Abstract

entre las estrategias desarrolladas para mejorar las condiciones funcionales del tracto gastrointestinal (TGi) de las aves se encuentra el empleo de nuevos aditivos funcionales alimenticios, y dentro de estas posibilidades está el uso de levaduras. el objetivo de este estudio fue evaluar el potencial funcional y nutricional de tres diferentes cepas de leva-duras aisladas de frutales colombianos y de dos levaduras comerciales, y sus efectos sobre las variaciones en la morfometría de vellosidades intestinales y productos de la microflora del ciego de pollos de engorde. Los pollos se distribuyeron al azar en 6 tratamientos: (tres diferentes cepas de levaduras nativas, dos controles con levaduras comerciales (Levapan®presentación seca y aB vista®) y un control sin levadura. Los datos se analizaron usando el procedimiento GLM de sas versión 9 (sasinst., inc. Cary. n. C.), se realizaron compara-ciones de los promedios utilizando la prueba de Tukey (P

Abstract

One of the strategies developed to improve the functional conditions of the gastrointestinal tract (GIT) of broilers is the use of alternative nutritional and functional additives. Among these alternatives, it has been recently evaluated the supplementation of yeasts in poultry feeding systems. In this context, the objective of this study was to evaluate the potential functional and nutritional role of 3 different strains of isolated yeasts from native fruits of Colombian ecosystems in males broiler and its effects on the variations of intestinal villus morphometry and products of the cecal microflora. The chicks were distributed at random in 6 treatments: 0,5% of the diet of 3 different native yeasts, two controls with commercial yeasts (Levapan® dry presentation and AB vista®) and a control group without yeast. They were carried out comparisons of the means with a level of significance of P, Entre las estrategias desarrolladas para mejorar las condiciones funcionales del tracto gastrointestinal (TGI) de las aves se encuentra el empleo de nuevos aditivos funcionales alimenticios, y dentro de estas posibilidades está el uso de levaduras.

Abstract

INTRODUCTION: Cephalometric soft tissue findings have shown correlation with pharyngeal width. Facial photographic analysis of patients with Obstructive Sleep Apnea (OSA) shows an increase in width and flatness of the midface. However, three-dimensional facial soft tissue morphology of children with OSA has not been studied. OBJECTIVE: The objective of the current study was to evaluate the association between facial morphology, upper airway volume, Polysomnography (PSG), and Pediatric Sleep Questionnaire (PSQ) findings in children with OSA versus controls. MATERIAL AND METHODS: The sample included de-identified pre-treatment Cone-beam Computed Tomography images, PSG and PSQ results of 36 children (mean age 6.8 ± 2.8) from one pediatric dental practice. Three-dimensional facial soft tissue landmarks were digitized using Mimics v.20 software. Upper airway volume was segmented into right nasal cavity (RNC), left nasal cavity (LNC), nasopharynx (NP), oropharynx (OP), and hypopharynx (HP). Apnea Hypopnea Index (AHI), Respiratory Disturbance Index (RDI) scores and Pediatric sleep questionnaire (PSQ) values were correlated with soft tissue measurements (a modified Farkas anthropometric analysis) and upper airway volumes using Pearson’s correlation. Student’s T-test was used to evaluate the difference between facial soft tissue measurements of children with obstructive sleep apnea (OSA) versus the control group. RESULTS: Experimental versus control: Polysomnography findings: Apnea/Hipopnea Index and Respiratory Disturbance Index were statistically higher in obstructive sleep apnea children compared to controls (p=
