Background. Studying the metabolic activity of gut microbiota has diagnostic value as it allows determination of the extent of microbiota perturbation, which is an important indicator of the post-operative gastrointestinal tract function.Objective. The study aimed at investigating the metabolic activity of gut microbiota in children during their first year of life which had undergone partial bowel resection.Methods. The spectrum of fecal short chain fatty acids (SCFA) was assessed using gas-liquid chromatography (GLC). Also, a comparative analysis of clinical and anamnestic data in children of the first year of life which had undergone partial bowel resection versus apparently healthy children was carried out.Results. Dynamic follow-up of children which had undergone bowel surgery revealed a reduction in acetic acid (С2) fecal level and increased propionic acid (С3) and oleic acid (С4) levels by the end of the first year of life. An age-adjusted comparative estimate has shown that the markers of anaerobic microflora, specifically, the level of propionic acid, are also high at the age of 7–12 months. A comparative analysis of metabolic activity of gut microbiota in children which had undergone bowel resection revealed lower fecal levels of oleic acid and higher total fatty acid content as compared to healthy children.Conclusion. Children which had undergone bowel resection, by the end of first year of life, have higher anaerobic and lower aerobic activity of gut microflora. A comparative analysis of metabolic activity of gut microflora in children which had undergone surgical treatment versus children of health groups I and II demonstrated the absence of significant differences between obligate (С2) and anaerobic (С3, anaerobic index [AI]) bacteria. However, lower fecal С4 values have been found in post-operative children during their second half-year of life, which may attest to persistent inflammation of the gut. Total fecal acid content throughout the entire follow-up period was higher in children which had undergone bowel resection, which reflects the activation of gut microbiota characterized by its species diversity.

Aim: to assess the rate of growth and metabolic activity of gut microbiota in infants who experienced bowel resection within the first year of life and received specialized nutrition with extensive hydrolyzed whey proteins with medium-chain triglycerides and nucleotides. Patients and Methods: prospective cohort study was conducted in two groups of infants. The study group included 37 infants with partial bowel resection within the first months of life. The control group included 75 healthy infants. Postoperatively, study group children were bottle-fed and received an infant formula (extensive hydrolized whey proteins with medium-chain triglycerides) till the age of 12 months. Some control group children were breast-fed while control group children on a mixed or formula feeding. In all children, antenatal and perinatal anamnesis and physical development within the first year of life were assessed. Additionally, the amounts of short-chain fatty acids in the stool were evaluated. Results: the rate of growth in infants who experienced bowel surgery was similar to that of healthy infants within the first year of life. By the age of 12 months, steady increase in the proportion of infants with average weight (SD -1 to +1) and significant reduction in the proportion of infants with low weight (SD -1 to -2) were reported. A group of overweight infants (SD +1 to +2) emerged since the age of 6 months. The specifics of metabolic activity of gut microbiota in children after surgery were a significant increase in propionic acid amount in the stool and a trend to an increase in anaerobic index by the age of 12 months. Conclusions: this growth pattern illustrates an adequate nutrition during the recovery of bowel functional activity and its ability to absorb and to uptake nutrients.

Abstract Research exists that evaluates the mechanics of swallowing respiratory coordination in healthy children and adults as well and individuals with swallowing impairment. The research program summarized in this article represents a systematic examination of swallowing respiratory coordination across the lifespan as a means of behaviorally investigating mechanisms of cortical modulation. Using time-locked recordings of submental surface electromyography, nasal airflow, and thyroid acoustics, three conditions of swallowing were evaluated in 20 adults in a single session and 10 infants in 10 sessions across the first year of life. The three swallowing conditions were selected to represent a continuum of volitional through nonvolitional swallowing control on the basis of a decreasing level of cortical activation. Our primary finding is that, across the lifespan, brainstem control strongly dictates the duration of swallowing apnea and is heavily involved in organizing the integration of swallowing and respiration, even in very early infancy. However, there is evidence that cortical modulation increases across the first 12 months of life to approximate more adult-like patterns of behavior. This modulation influences primarily conditions of volitional swallowing; sleep and naïve swallows appear to not be easily adapted by cortical regulation. Thus, it is attention, not arousal that engages cortical mechanisms.

OBJECTIVEThe authors evaluated the long-term outcome of their treatment protocol for Muenke syndrome, which includes a single craniofacial procedure.METHODSThis was a prospective observational cohort study of Muenke syndrome patients who underwent surgery for craniosynostosis within the first year of life. Symptoms and determinants of intracranial hypertension were evaluated by longitudinal monitoring of the presence of papilledema (fundoscopy), obstructive sleep apnea (OSA; with polysomnography), cerebellar tonsillar herniation (MRI studies), ventricular size (MRI and CT studies), and skull growth (occipital frontal head circumference [OFC]). Other evaluated factors included hearing, speech, and ophthalmological outcomes.RESULTSThe study included 38 patients; 36 patients underwent fronto-supraorbital advancement. The median age at last follow-up was 13.2 years (range 1.3–24.4 years). Three patients had papilledema, which was related to ophthalmological disorders in 2 patients. Three patients had mild OSA. Three patients had a Chiari I malformation, and tonsillar descent < 5 mm was present in 6 patients. Tonsillar position was unrelated to papilledema, ventricular size, or restricted skull growth. Ten patients had ventriculomegaly, and the OFC growth curve deflected in 3 patients. Twenty-two patients had hearing loss. Refraction anomalies were diagnosed in 14/15 patients measured at ≥ 8 years of age.CONCLUSIONSPatients with Muenke syndrome treated with a single fronto-supraorbital advancement in their first year of life rarely develop signs of intracranial hypertension, in accordance with the very low prevalence of its causative factors (OSA, hydrocephalus, and restricted skull growth). This illustrates that there is no need for a routine second craniofacial procedure. Patient follow-up should focus on visual assessment and speech and hearing outcomes.

The early life gut microbiota has been reported to be involved in neonatal weight gain and later infant growth. Therefore, this early microbiota may constitute a target for the promotion of healthy neonatal growth and development with potential consequences for later life. Unfortunately, we are still far from understanding the association between neonatal microbiota and weight gain and growth. In this context, we evaluated the relationship between early microbiota and weight in a cohort of full-term infants. The absolute levels of specific fecal microorganisms were determined in 88 vaginally delivered and 36 C-section-delivered full-term newborns at 1 month of age and their growth up to 12 months of age. We observed statistically significant associations between the levels of some early life gut microbes and infant weight gain during the first year of life. Classifying the infants into tertiles according to their Staphylococcus levels at 1 month of age allowed us to observe a significantly lower weight at 12 months of life in the C-section-delivered infants from the highest tertile. Univariate and multivariate models pointed out associations between the levels of some fecal microorganisms at 1 month of age and weight gain at 6 and 12 months. Interestingly, these associations were different in vaginally and C-section-delivered babies. A significant direct association between Staphylococcus and weight gain at 1 month of life was observed in vaginally delivered babies, whereas in C-section-delivered infants, lower Bacteroides levels at 1 month were associated with higher later weight gain (at 6 and 12 months). Our results indicate an association between the gut microbiota and weight gain in early life and highlight potential microbial predictors for later weight gain.

To document the incidence of and neonatal factors associated with abnormal shoulder girdle muscle tone in premature infants at follow-up, we studied 125 consecutively admitted infants weighing &lt; 1,750 g treated in The Children's Hospital of Philadelphia intensive care nursery and subsequently seen in the Neonatal Follow-up Program up to 18 months of age. Fifty-seven infants (46%) displayed abnormal shoulder girdle muscle tone which presented clinically as scapular retractions. These infants had significantly lower birth weights (P &lt; .001) and gestational age (P &lt; .001) as well as a higher incidence of acute and chronic pulmonary disease (P &lt; 0.01) and CNS insults (P &lt; .05) when compared with infants without scapular retractions. The 57 infants with scapular retractions were further divided into two groups: 42 infants (74%) in whom scapular retractions were associated with generalized mild hypertonicity and 15 infants (26%) in whom scapular retractions compensated for trunk and neck hypotonicity. The infants with scapular retractions and hypotonicity had a significantly higher incidence of neonatal neurologic morbidity including seizures, major resuscitations, and birth asphyxia (P &lt; .01) when compared with the infants with scapular retractions and hypertonicity. Shoulder girdle tone abnormalities in the first year of life inhibit crawling, sitting, and object manipulation and, therefore, may manifest as delays in motor development. Identification of infants with significant neonatal risk factors for tone abnormalities is important to allow for earlier therapeutic intervention.

Objective. To investigate the natural history of and risk factors for allergic rhinitis in the first 6 years of life. Methods. Parents of 747 healthy children followed from birth completed a questionnaire when the child was 6 years old. Data were obtained regarding physician-diagnosed allergic rhinitis (PDAR), associated symptoms, and age at onset. Risk-factor data were taken from earlier questionnaires, and data regarding immunoglobulin E (IgE) and skin-test reactivity were obtained at age 6. Results. By the age of 6, 42% of children had PDAR. Children whose rhinitis began in the first year of life had more respiratory symptoms at age 6 and were more likely to have a diagnosis of asthma. Early introduction of foods or formula, heavy maternal cigarette smoking in the first year of life, and higher IgE, as well as parental allergic disorders, were associated with early development of rhinitis. Risk factors for PDAR that remained significant in a multivanate model included maternal history of physician-diagnosed allergy (odds ratio: 2.2, 95% confidence interval: 1.35-3.54), asthma in the child (4.06, 2.06-7.99), and IgE greater than 100 IU/mL at age 6 (1.93, 1.18-3.17). The odds for atopic as opposed to nonatopic PDAR were significantly higher only among those with high IgE and those who had dogs. Conclusion. Allergic rhinitis developing in the first years of life is an early manifestation of an atopic predisposition, which may be triggered by early environmental exposures.

ObjectiveTo determine whether potential breast milk exposure to interferon-beta (IFN-β) or glatiramer acetate (GA) is safe for the infant.MethodsWe identified 74 infants born to 69 women with MS who breastfed under IFN-β (n = 39), GA (n = 34), or both (n = 1). Women had been enrolled into the German Multiple Sclerosis and Pregnancy Registry during pregnancy. Data were obtained from standardized, telephone-administered questionnaires completed by the mother during pregnancy and at 1, 3, 6, and 12 months postpartum and the infant's take-home medical record.ResultsThe median duration of exposed breastfeeding was 8.5 months (wide interquartile range: 4.9–12.7 months). Physical growth curves during the first year of life were consistent with national, sex-specific growth curves. Median body measurements were consistent with national medians. Most children (n = 71, 96%) had normal motor and language development. Gross motor delay was reported in 3 children, of whom 1 remained delayed at last follow-up (3.9 years old) and 2 were normal by 0.9 and 4.1 years old. The proportion of children hospitalized at least once (girls n = 2, 7%, and boys n = 6, 14%) and the proportion of children with at least one episode of systemic antibiotic use during the first year of life (girls n = 7, 23%, and boys n = 8, 18%) are consistent with national averages.ConclusionPotential breast milk exposure to IFN-β or GA did not increase the risk of common adverse infant outcomes in the first year of life. Taken together with the benefits of breastfeeding and low biological plausibility of risk, women with MS who wish to resume IFN-β or GA postpartum can be encouraged to breastfeed.

Background: Reaching early and definitive diagnosis in infants with cystic fibrosis (CF) transmembrane conductance regulator-related metabolic syndrome (CRMS)/CF screen-positive, inconclusive diagnosis (CFSPID) is a priority of all CF newborn screening programs. Currently, sweat testing is the gold standard for CF diagnosis or exclusion. We assessed outcomes in a cohort of Italian CRMS/CFSPID infants who underwent repeat sweat testing in the first year of life. Methods: This multicentre, prospective study analysed clinical data and outcomes in CRMS/CFSPID infants born between September 1, 2018 and December 31, 2019, and followed until June 30, 2020. All subjects underwent CF transmembrane conductance regulator (CFTR) gene sequencing and the search for CFTR macrodeletions/macroduplications, and repeat sweat testing in the first year of life. Results: Fifty subjects (median age at end of follow-up, 16 months [range, 7–21 months]) were enrolled. Forty-one (82%) had the first sweat chloride in the intermediate range. During follow up, 150 sweat tests were performed (range, 1–7/infant). After a median follow-up of 8.5 months (range 1–16.2 months), 11 (22%) subjects were definitively diagnosed as follows: CF (n=2 [4%]) at 2 and 5 months, respectively; healthy carrier (n=8 [16%]), at a median age of 4 months (range 2–8 months); and healthy (n=1 [2%]) at 2 months of age. Inconclusive diagnosis remained in 39 (78%) infants. Conclusions: Early repeat sweat testing in the first year of life can shorten the time to definitive diagnosis in screening positive subjects with initial sweat chloride levels in the intermediate range.
