Bowel function and associated risk factors at preschool and early childhood age in children with anorectal malformation type rectovestibular fistula: An ARM-Net consortium study.

Background: Outcome of patients operated for anorectal malformation (ARM) type rectovestibular fistula (RVF) is generally considered to be good. However, large multi-center studies are scarce, mostly describing pooled outcome of different ARM-types, in adult patients. Therefore, counseling parents concerning the bowel function at early age is challenging.

Use of 5-mm Staple in Neonatal Intestinal Surgery.

The use of staples to perform intestinal anastomosis in children has gained popularity in the past years. The aim of this study is to evaluate the outcomes of pediatric patients who underwent intestinal anastomosis with a 5-mm staple in a tertiary health care center. From April 2017 to November 2019, the records of all pediatric patients who underwent intestinal anastomosis with a 5-mm staple were retrospectively revised.

Daily changes in GFAP expression in radial glia of the olfactory bulb in rabbit pups entrained to circadian feeding.

When food is restricted daily to a fixed time, animals show uncoupled molecular, physiological and behavioral circadian rhythms from those entrained by light and controlled by the suprachiasmatic nucleus. The loci of the food-entrainable oscillator and the mechanisms by which rhythms emerge are unclear. Using animals entrained to the light-dark cycle, recent studies indicate that astrocytes in the suprachiasmatic nucleus play a key role in the regulation of circadian rhythms.

IMPACT OF THE APPENDICEAL POSITION ON THE DIAGNOSIS AND TREATMENT OF PEDIATRIC APPENDICITIS.

Objective: To investigate how symptoms vary according to the appendiceal position in pediatric patients and to demonstrate that the laparoscopic approach is safe and effective in any appendiceal location by comparing each location to another.

Methods: The medical records of 1,736 children aged 14 or younger who underwent laparoscopic appendectomy over a period of 14 years were analyzed retrospectively. Patients were divided according to the position of the appendiceal tip into four groups: anterior, pelvic, retrocecal and subhepatic.

Circadian feeding entrains anticipatory metabolic activity in piriform cortex and olfactory tubercle, but not in suprachiasmatic nucleus.

Animals maintained under conditions of food-availability restricted to a specific period of the day show molecular and physiological circadian rhythms and increase their locomotor activity 2-3h prior to the next scheduled feeding, called food anticipatory activity (FAA). Although the anatomical substrates and underlying mechanisms of the food-entrainable oscillator are not well understood, experimental evidence indicates that it involves multiple structures and systems. Using rabbit pups entrained to circadian nursing as a natural model of food restriction, we hypothesized that the anterior piriform cortex (APCx) and the olfactory tubercle (OTu) are activated during nursing-associated FAA.
