Issa C, Hobeika M, Khairallah W, Al-Jawaldeh A, Batal M. Timing and types of fluids and foods first introduced in a representative sample of toddlers attending day care programs across Lebanon: Are parents following international recommendations? J Pediatr Nurs 2022; 62:e45-e53. [PMID: 34266717 DOI: 10.1016/j.pedn.2021.07.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Revised: 07/01/2021] [Accepted: 07/05/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND Current WHO's recommendation for optimal infant feeding advises exclusive breastfeeding for 6 months. After this initial period, infants should receive nutritionally adequate and safe complementary food starting from the age of 6 months with continued breastfeeding up to 2 years of age or beyond. PURPOSE This study examined the timing and types of fluids and foods first introduced in a representative sample of toddlers (n = 1051) from 79 daycares across Lebanon. Questionnaires were self-administered to parents of toddlers (12-36 months) with a participation rate of 67%. RESULTS Results showed that more than half of toddlers (55.7%) were introduced to infant formula within their first month of life. Around two-thirds received water as the first type of additional fluid (62.5%) with a mean age of 3.86 ± 2.15 months and fruits or cooked vegetables (69.7%) as the first types of food introduced with a mean age of 5.73 ± 1.56 months. Unfortunately, two-third (67.3%) were not breastfed after solid food introduction. PRACTICE IMPLICATIONS Our data on current suboptimal feeding practices in Lebanon shows the need to reinforce BF and CF practices recommendations and guidelines at the community, social and health system levels. CONCLUSIONS In the absence of specific recommendations and with the poor involvement of the various stakeholders, it was noted that more than half of the parents were not following the WHO recommendation concerning unnecessary fluid supplementation of infants and were introducing food before the recommended age of 6 months; moreover, only a minority of mothers continued breastfeeding after introducing food to their infants.

Vitamin A deficiency exacerbates extrinsic atopic dermatitis development by potentiating type 2 helper T cell-type inflammation and mast cell activation. Clin Exp Allergy 2020; 50:942-953. [PMID: 32559330 DOI: 10.1111/cea.13687] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2019] [Revised: 04/30/2020] [Accepted: 05/10/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND Vitamin A deficiency (VAD) has been hypothesized to play a role in the pathophysiology of atopic dermatitis (AD). OBJECTIVE We sought to verify whether VAD can exacerbate AD development, and explore the possible pathophysiologic mechanism. METHODS We detected serum vitamin A (VA) concentration in different phenotypes of AD infants (intrinsic AD, iAD and extrinsic AD, eAD), and established ovalbumin (OVA) percutaneous sensitized AD model and passive cutaneous anaphylaxis (PCA) model on VAD and vitamin A supplementation (VAS) model in wild-type mice (C57BL/6) and established AD model on both normal VA (VAN) and VAD feeding mast cell deficiency mice (ckitw-sh/w-sh ). RESULTS The average serum VA concentration of eAD was significantly lower than that of iAD, as well as healthy controls. In OVA-induced C57BL/6 mouse AD model, compared with VAN group, VAD mice manifested significantly more mast cells accumulation in the skin lesions, more severe Th2-mediated inflammation, including higher serum IgG1 and IgE levels, more IL-4, IL-13 mRNA expression in OVA-sensitized skin, and lower Th1 immune response, including lower serum IgG2a and IFN-γ mRNA expression in the skin. But there was no significant difference in the expression of IL-17 mRNA between OVA-treated skin of VAN and VAD mice. However, in OVA-induced ckitw-sh/w-sh mouse AD model, we did not find any significant differences in the above measurements between VAD and VAN group. In PCA model, VAD mice showed remarkable more blue dye leakage than that in VAN mice. Compared with VAD group, the above-mentioned inflammatory measurements in VAS group and VAN group were similar in OVA-induced AD model mice. CONCLUSIONS AND CLINICAL RELEVANCE VAD can exacerbate extrinsic AD by augmenting Th2-mediated inflammation and mast cell activation. Therapeutic VAS can rescue VAD-aggravated eAD. It may provide a new strategy for future prevention or treatment of atopic dermatitis.

Abstract
BACKGROUND There is accumulating evidence in studies of allergic diseases in humans and dogs that environmental experiences during the first months of life can influence the development of allergic disease. No prospective study has evaluated this in veterinary medicine. HYPOTHESIS/OBJECTIVES To assess early-life risk factors for canine atopic dermatitis (cAD) and estimate its heritability. ANIMALS A West Highland white terrier birth cohort (n = 107) followed up to three years of age recording the development of cAD. METHODS AND MATERIALS The effect of environmental factors [house dust mites (HDM), hygiene, feeding, lifestyle] and early-life determinants [breeder, mode of delivery, birth season, sex, litter size, early-life immunoglobulin E (IgE) levels] were assessed, using Stata SE 15.1 statistical analysis. Heritabilities were estimated using the R program packages MCMCglmm and QGglmm. RESULTS Maternal allergic status [P = 0.013, odds ratio (OR 3.3)], male sex (P = 0.06), mode of delivery (P = 0.12), breeder (P = 0.06), presence of HDM (P = 0.11) and environmental hygiene level (P = 0.15) were identified as possible influence factors by bivariate analyses. In the multivariate analysis the male sex was significantly associated with the development of cAD in the offspring (P = 0.03, OR 2.4). The heritabilities on the observed scale were 0.31 (direct), 0.04 (maternal genetic effects) and 0.03 (maternal permanent environmental effects). CONCLUSION AND CLINICAL IMPORTANCE These results suggest that several environmental factors could influence the development of cAD but clearly demonstrate the genetic influence of the individual and the dam. Further studies are needed to identify specific environmental factors, which could be potential targets for primary disease intervention.

Abstract
Rapid economic and cultural transition in the United Arab Emirates (UAE) has been accompanied by new challenges to public health; most notably a rapid rise in chronic disease. Breastfeeding is known to improve health outcomes in adulthood, is associated with reduced risk of developing chronic disease, and is therefore an important public health issue for this rapidly increasing population. Factors associated with infant feeding practices were examined in a cohort of 125 Emirati women and their infants, with data collected at birth and 3, 6 and 15 months postpartum by questionnaires and interviews. Participants were recruited in the Corniche Hospital, the main maternity hospital in the city of Abu Dhabi. Factors affecting the duration of breastfeeding and the introduction of complementary foods were investigated using univariate and multivariate statistics. Recommended infant feeding practices, such as exclusive breastfeeding for the first six months of life and timely introduction of appropriate complementary foods, were poorly adhered to. Factors implicated in early cessation of breastfeeding included: time to first breastfeed, mother's education level, employment status and early introduction of complementary foods.

Abstract
PURPOSE The objective of this study was to examine the factors associated with initiation and continuation of breastfeeding among Korean women in relation to their employment status. METHODS Data were collected using a web-based self-administered questionnaire from 1,031 Korean mothers living in Seoul with babies younger than 24 months. Demographic characteristics, education on breastfeeding, rooming in, breastfeeding during hospital stay, and breastfeeding knowledge were examined. Multivariate logistic regression analyses were performed to identify factors associated with initiation and continuation at 1, 6 and 12 months according to mothers' employment status. RESULTS Breastfeeding initiation rates were similar regardless of mothers' employment status. Continuation rates decreased for both groups of mothers, but were significantly lower among employed mothers at all duration points. Unemployed mothers who were able to keep their babies in the same room during the hospital stay were more likely to initiate breastfeeding. The factor that was consistently associated with breastfeeding continuation for all duration points among unemployed mothers was whether the mother breastfed during the hospital stay. Higher knowledge scores and having an infant with atopic dermatitis were also associated with breastfeeding continuation at 6 months and 12 months, respectively for unemployed mothers, and receiving education on breastfeeding was associated with 12-month continuation for employed mothers. CONCLUSION These results emphasize the significant roles of hospitals for breastfeeding initiation and continuation, with rooming-in, initial breastfeeding practice and education during hospital stay as important practices. In addition, for working mothers to continue their breastfeeding, significant support from the workplace is crucial.

Abstract
OBJECTIVE To evaluate the risk of childhood hospitalization associated with infant feeding patterns at 6-8 weeks of age in Scotland. STUDY DESIGN A retrospective population level study based on the linkage of birth, death, maternity, infant health, child health surveillance, and admission records for children born as single births in Scotland between 1997 and 2009 (n = 502 948) followed up to March 2012. Descriptive analyses, Kaplan Meier tests, and Cox regression were used to quantify the association between the mode of infant feeding and risk of childhood hospitalization for respiratory, gastrointestinal, and urinary tract infections, and other common childhood ailments during the study period. RESULTS Within the first 6 months of life, there was a greater hazard ratio (HR) of hospitalization for common childhood illnesses among formula-fed infants (HR 1.40; 95% CI 1.35-1.45) and mixed-fed infants (HR 1.18; 95% CI 1.11-1.25) compared with infants exclusively breastfed after adjustment for parental, maternal, and infant health characteristics. Within the first year of life and beyond, a greater relative risk of hospitalization was observed among formula-fed infants for a range of individual illnesses reported in childhood including gastrointestinal, respiratory, and urinary tract infections, otitis media, fever, asthma, diabetes, and dental caries. CONCLUSIONS Using linked administrative data, we found greater risks of hospitalization in early childhood for a range of common childhood illnesses among Scottish infants who were not exclusively breastfed at 6-8 weeks of age.

Abstract
BACKGROUND Atopic dermatitis (AD) is a common inflammatory disorder of skin with significant comorbidities. AD care often requires a combination of treatment approaches, including emollients, topical steroids, systemic immunosuppressants and/or phototherapy. PURPOSE Our purpose was to review recent randomized controlled trials (RCT) and systematic reviews of AD treatments. METHODS A MEDLINE search was performed focusing on RCTs of AD treatments, with a sample size ≥ 15, and systematic reviews published from 2011 to 2013, limited to the English language. A total of 53 manuscripts met the inclusion/exclusion criteria, including 44 RCTs and nine systematic reviews. RESULTS Investigator-initiated RCTs support the use of the systemic agents cyclosporine, methotrexate, azathioprine and mycophenolate mofetil. In one RCT, petrolatum was found to be as effective as creams containing ceramides or glycyrrhetinic acid. Additional therapeutic approaches supported by RCTs include balneotherapy, oral and/or topical probiotics, nutritional interventions, vitamin D with or without vitamin E supplementation, as well as several new topical and complementary medicines. CONCLUSIONS Advances have been made with respect to AD treatment in the past few years through the use of well designed RCTs and comparative efficacy studies. However, more well designed RCTs and investigator-initiated studies are needed in order to improve the care of AD patients.

Abstract
In the last decades several studies tested the hypothesis that at early development stages certain foods or nutrients, in specific amounts, fed during limited sensitive periods, may determine an endocrine metabolic asset leading to clinical alterations that take place decades later (early nutritional programming of long term health). Evidence is mounting for programming effects of infant feeding. Observational studies indicate that breast feeding, relative to formula feeding, reduces the risk for obesity at school age by about 20% even after adjustment for biological and sociodemographic confounders. Moreover, breastfeeding is constantly associated with increased neurodevelopmental scores up to early adulthood, while its outcome in terms of delayed decay of brain function is still unknown. Besides the environment surrounding breastfeeding, specific nutrients within human milk may play a direct role. With the introduction of solids the major changes in diet are represented by the sudden decrease of fat intake from 50 to 30% of total energy. A protein excess, commonly found throughout all European Countries, has been associated to a higher risk of adiposity in early childhood, as confirmed by first reports from a large European trial. The amount of fat does not seem to be associated with later adiposity, while its quality may affect blood lipoproteins, blood pressure and neurodevelopmental performance. Early intake of dietary fibers might also have beneficial effects. Epidemiologic data show that episodes of rapid growth (growth acceleration hypothesis), whichever the dietary habits, are associated with later unfavorable health conditions and should be prevented.

Abstract
Single nucleotide polymorphisms (SNPs) can play a direct or indirect role in phenotypic expression in food allergy pathogenesis. Our goal was to quantitate the expression of SNPs in relevant cytokines that were expressed in food allergic patients. SNPs in cytokine genes IL-4 and IL-10 are known to be important in IgE generation and regulation. We examined IL-4 (C-590T), IL-4Rα (1652A/G) and IL-10 (C-627A) SNPs using real-time PCR followed by restriction fragment length polymorphism (RFLP) analysis. Our results show that the AA, AG and GG genotypes for IL-4Rα (1652A/G) polymorphisms were statistically different in radioallergosorbent test (RAST) positive versus negative patients, and although no statistically significant differences were observed between genotypes in the IL-4 (C-590T) and IL-10 (C-627A) SNPs, we observed a significant decrease in IL-4 (C-590T) gene expression and increase in IL-4Rα (1652A/G) and IL-10 (C-627A) gene expression between RAST(+) versus RAST(-) patients, respectively. We also observed significant modulation in the protein expression of IL-4 and IL-10 in the serum samples of the RAST(+) patients as compared to the RAST(-) patients indicating that changes in SNP expression resulted in altered phenotypic response in these patients.

Abstract
Aim. To measure the association between infant feeding practices and parent-reported nut allergy in school entrant children. Method. The Kindergarten Health Check Questionnaire was delivered to all 110 Australian Capital Territory (ACT) primary schools between 2006 and 2009. Retrospective analyses were undertaken of the data collected from the kindergarten population. Results. Of 15142 children a strong allergic reaction to peanuts and other nuts was reported in 487 (3.2%) and 307 (3.9%), children, respectively. There was a positive association between parent reported nut allergy and breast feeding (OR = 1.53; 1.11–2.11) and having a regular general practitioner (GP) (OR = 1.42; 1.05–1.92). A protective effect was found in children who were fed foods other than breast milk in the first six months (OR = 0.71; 0.60–0.84). Conclusion. Children were at an increased risk of developing a parent-reported nut allergy if they were breast fed in the first six months of life.

Abstract
This paper resulted from a conference entitled "Lactation and Milk: Defining and refining the critical questions" held at the University of Colorado School of Medicine from January 18-20, 2012. The mission of the conference was to identify unresolved questions and set future goals for research into human milk composition, mammary development and lactation. We first outline the unanswered questions regarding the composition of human milk (Section I) and the mechanisms by which milk components affect neonatal development, growth and health and recommend models for future research. Emerging questions about how milk components affect cognitive development and behavioral phenotype of the offspring are presented in Section II. In Section III we outline the important unanswered questions about regulation of mammary gland development, the heritability of defects, the effects of maternal nutrition, disease, metabolic status, and therapeutic drugs upon the subsequent lactation. Questions surrounding breastfeeding practice are also highlighted. In Section IV we describe the specific nutritional challenges faced by three different populations, namely preterm infants, infants born to obese mothers who may or may not have gestational diabetes, and infants born to undernourished mothers. The recognition that multidisciplinary training is critical to advancing the field led us to formulate specific training recommendations in Section V. Our recommendations for research emphasis are summarized in Section VI. In sum, we present a roadmap for multidisciplinary research into all aspects of human lactation, milk and its role in infant nutrition for the next decade and beyond.
