Prematurity and the Transition to Self-Feeding: A Longitudinal Study on Mother-Child Interactions from 18 to 30 Months

The present research expanded on the literature investigating mother-child feeding and playing interactions during the transition to self-feeding (18-30 months) in the preterm population. Maternal and infant factors were also considered. A total of 69 mother-child dyads (44 preterm and 25 full-term) participated in the research. Assessments took place at 18, 24, and 30 months of the child. At each assessment, mother-child interactions during feeding (Study 1) and during a doll-play (DP) situation representing feeding (Study 2) were video recorded and later coded, respectively through the SVIA (Ammaniti et al., 2006) and the EAS (Biringen, 2008). Moreover, the child’s development was assessed through the Griffiths Scale (Griffiths, 1996, 2006) and mothers filled the BDI-II (Beck & Steer, 1996), the STAI (Spielberg, 1983), and an anamnestic questionnaire built Ad-Hoc. Results of Study 1 showed a greater occurrence of dysfunctional feeding interactions in the preterm compared to the full-term group from 18 to 30 months. Specifically, preterm dyads reported greater maternal negative affective state, greater interactional conflict and lower dyadic reciprocity. Moreover, a significantly lower percentage of children in the preterm group reached eating autonomy compared to the full-term group during the 18-30 months period. Furthermore, adverse past feeding history (difficult breastfeeding and reflux) and lower total scores on the Griffiths were associated to a higher risk of child’s food refusal. Results of Study 2 showed that the preterm group displayed lower emotional availability than the full-term group during mother-child DP interactions from 18 to 30 months, with lower maternal sensitivity, greater maternal intrusiveness, and lower child’s involvement. These findings indicate that special attention should be paid to support mother-child interactions during the transition to self-feeding in the preterm population in order to foster the mother-child relationship and promote the child’s healthy eating behavior and affective development

The Focal Play Therapy: A Clinical Approach to Promote Child Health and Family Well-being

Eating and evacuation disorders can cause serious health problems for children. Early recognition and early treatment require a multifactor intervention based on a collaborative relationship between pediatricians, psychotherapists and other health professionals. In this context the Focal Play Therapy (FPT) with children and parents is a psychodynamic model of intervention that improves parental ability to cope with child's difficulties. Parental engagement in child interventions allows to understand child's symptoms within family dynamics and to build an alliance with parents that represents a crucial variable of an effective psychological support for children and families. In the present study data were collected from 17 parental couples and their preschool children at two time points (1st and 6th FPT sessions) marking the first phase of this intervention. This phase was aimed to the assessment of child's symptoms within family relationships and to the promotion of the alliance with parents. Families were in treatment at the Psychological Consultation Center for Children and Parents located at the Department of Psychology of the University of Bologna (Italy). This Center provides health assessment and intervention services to children and their families. We investigated the alliance from both parents and therapist points of view along with other parental and child outcome variables implied in clinical works with children and families. Alliance scores were obtained through the Working Alliance Inventory and the System for Observing Family Therapy Alliances, two measures used in individual and family settings, respectively. Parenting stress and parent-child interactions were investigated using the Parenting Stress Index and the Emotional Availability Scales. Furthermore, paired t-tests were run to detect changes on parental and child variables. Findings advise that special attention should be paid to the building of an early alliance with parents. In this regard the FPT is specifically designed to promote the parent-therapist alliance in the context of child health and family well-being

SerpinE1 drives a cell-autonomous pathogenic signaling in Hutchinson-Gilford progeria syndrome

Hutchinson-Gilford progeria syndrome (HGPS) is a rare, fatal disease caused by Lamin A mutation, leading to altered nuclear architecture, loss of peripheral heterochromatin and deregulated gene expression. HGPS patients eventually die by coronary artery disease and cardiovascular alterations. Yet, how deregulated transcriptional networks at the cellular level impact on the systemic disease phenotype is currently unclear. A genome-wide analysis of gene expression in cultures of primary HGPS fibroblasts identified SerpinE1, also known as Plasminogen Activator Inhibitor (PAI-1), as central gene that propels a cell-autonomous pathogenic signaling from the altered nuclear lamina. Indeed, siRNA-mediated downregulation and pharmacological inhibition of SerpinE1 by TM5441 could revert key pathological features of HGPS in patient-derived fibroblasts, including re-activation of cell cycle progression, reduced DNA damage signaling, decreased expression of pro-fibrotic genes and recovery of mitochondrial defects. These effects were accompanied by the correction of nuclear abnormalities. These data point to SerpinE1 as a novel potential effector and target for therapeutic interventions in HGPS pathogenesis

Adherence to the Traditional Mediterranean Diet and Human Milk Composition: Rationale, Design, and Subject Characteristics of the MEDIDIET Study

Introduction: Knowledge about how a lactating woman's diet influences the composition of her breast milk is still very limited. In particular, no study has evaluated the role of adherence to the Mediterranean diet on human milk characteristics.Aim: We carried out an observational study to investigate the influence of mother adherence to a Mediterranean diet on her breast milk composition.Methods: Between 2012 and 2014, 300 healthy mothers, who exclusively breastfed their babies, were enrolled from five centers across Italy. During a visit to the hospital center 6 weeks after childbirth these women were asked to provide a sample of their freshly expressed breast milk and to answer a series of questions on personal characteristics and lifestyle factors. The application of a validated food frequency questionnaire allowed the collection of detailed dietary habits. Milk was collected and then stored until chemical analyses were performed. The study has been registered (Trial Registration: Dutch Trial register NTR3468). Descriptive analyses on baseline characteristics of mothers and babies were carried out on the participants, overall and stratified by center.Results: The participants had a mean age of 33 years (SD = 4.06), and a pre-pregnancy BMI of 22.3 Kg/m2 (SD = 3.22). Forty-seven percent gave birth to their first child, 40% to the second 13% to the third or subsequent child. Babies had a mean birth weight of 3,324 g (DS = 389), and a mean length of 51 cm (SD = 1.94). Fifty-three percent were males.Conclusion: The present work provides the general description and the characteristics of mothers and babies included in the MediDiet study

Phylogenetic and Metabolic Tracking of Gut Microbiota during Perinatal Development

The colonization and development of gut microbiota immediately after birth is highly variable and depends on several factors, such as delivery mode and modality of feeding during the first months of life. A cohort of 31 mother and neonate pairs, including 25 at-term caesarean (CS) and 6 vaginally (V) delivered neonates (DNs), were included in this study and 121 meconium/faecal samples were collected at days 1 through 30 following birth. Operational taxonomic units (OTUs) were assessed in 69 stool samples by phylogenetic microarray HITChip and inter- and intra-individual distributions were established by inter-OTUs correlation matrices and OTUs co-occurrence or co-exclusion networks. H-1-NMR metabolites were determined in 70 stool samples, PCA analysis was performed on 55 CS DNs samples, and metabolome/OTUs co-correlations were assessed in 45 CS samples, providing an integrated map of the early microbiota OTUs-metabolome. A microbiota "core" of OTUs was identified that was independent of delivery mode and lactation stage, suggesting highly specialized communities that act as seminal colonizers of microbial networks. Correlations among OTUs, metabolites, and OTUs-metabolites revealed metabolic profiles associated with early microbial ecological dynamics, maturation of milk components, and host physiology.Peer reviewe

Adherence to Mediterranean Diet of Breastfeeding Mothers and Fatty Acids Composition of Their Human Milk: Results From the Italian MEDIDIET Study

Background and Aims: The content of fatty acids (FA) in human milk may be influenced by maternal nutrition. We evaluated the role of a Mediterranean diet in influencing the content of FA in human milk among 282 breastfeeding mothers participating in the MEDIDIET study. Materials and Methods: Mediterranean Diet Score (MDS), a composite index, was used to evaluate adherence to the Mediterranean diet. It includes 9 components (i.e., vegetables, fruit, cereals, legumes, monounsaturated to saturated FA ratio – MUFA/SFA, fish, dairy products, meat, and alcohol) and therefore potentially ranges from 0 (no adherence) to 9 (complete adherence) points. None of the mothers obtained the highest score due to the low alcohol consumption in the study population. Mothers were categorized in approximate tertiles of adherence: 0–3 (34.4%), 4 (26.2%), and 5–8 points (39.4%). The mean content of FA across categories of MDS was compared using ANOVA and test for trend. Results: A high adherence of breastfeeding mothers to the Mediterranean diet was associated with lower content of SFA in human milk (42.58 ± 4.36 for MDS = 0–3, 42.58 ± 4.89 for MDS = 4, and 40.92 ± 5.22% of fats for MDS = 5–8 points; p ANOVA and p for trend = 0.02). Conversely, a high adherence was associated with higher content of MUFA in human milk (43.27 ± 4.27 for MDS = 0–3, 43.27 ± 4.47 for MDS = 4, and 45.24 ± 5.22% of fats for MDS = 5–8 points; p ANOVA and p for trend < 0.01), ω-3 FA (1.07 ± 0.25 for MDS = 0–3, 1.22 ± 0.49 for MDS = 4, and 1.31 ± 0.51% of fats for MDS = 5–8 points; p ANOVA and p for trend < 0.01), and the major types of ω-3 FA (i.e., α-linolenic acid – ALA, eicosapentaenoic acid – EPA, docosahexaenoic acid – DHA, docosapentaenoic acid – DPA). These associations were mainly driven by the adherence to the vegetables, MUFA/SFA, fish, and dairy products components of the Mediterranean diet. Conclusion: A high adherence to the Mediterranean diet was associated with human milk showing a lower content of SFA and higher content of MUFA and ω-3 FA, including DHA. The Mediterranean diet may contribute in human milk production with higher content of specific FA which is directly involved in infant’s neural and visual development, as reported by previous studies

Mammal responses to global changes in human activity vary by trophic group and landscape

Wildlife must adapt to human presence to survive in the Anthropocene, so it is critical to understand species responses to humans in different contexts. We used camera trapping as a lens to view mammal responses to changes in human activity during the COVID-19 pandemic. Across 163 species sampled in 102 projects around the world, changes in the amount and timing of animal activity varied widely. Under higher human activity, mammals were less active in undeveloped areas but unexpectedly more active in developed areas while exhibiting greater nocturnality. Carnivores were most sensitive, showing the strongest decreases in activity and greatest increases in nocturnality. Wildlife managers must consider how habituation and uneven sensitivity across species may cause fundamental differences in human–wildlife interactions along gradients of human influence.Peer reviewe
