Compared with the more physically fragile extremely/very preterm children (E/VPT), moderate-to-late preterm (MLPT) children-the large majority of preterm births-are underrepresented in research. This gap persists despite evidence that MLPT children exhibit more difficulties than full-term peers in certain domains. This scoping review surveys the literature on psychological forms of self-regulation in MLPT children, organized around three levels: emotional, behavioral, and cognitive regulation.

When foster caregivers provide responsive care, children benefit from a nurturing, individualized environment that supports socioemotional development. However, foster care does not eliminate developmental challenges.

Background: The shortage of foster families to protect maltreated children requires urgent and effective solutions supported by theoretical and evidence-based frameworks. However, most research has focused only on the perspective of foster parents and has not been theoretically grounded. To the best of our knowledge, profiles of prospective foster families with representative samples from the general population have not yet been identified.

Despite evidence highlighting the detrimental effects of institutionalization, only a small percentage of children (less than 4%) are currently placed in family foster care in the country. In response to European directives for deinstitutionalization, Portuguese legislation now prioritizes non-kinship family foster care as the preferred alternative for young children in need of care.

There is compelling evidence that the quality of caregiver-child interactions during toddlerhood and the preschool years supports the development of executive function (EF) (Bernier et al., 2010; 2015; 2016; Fay-Stammbach et al., 2014; Geeraerts et al.

Participants included 48 infants born prematurely (gestational age < 37 weeks) and their mothers, assessed when infants were 12 months old corrected for prematurity. The examined variables comprised both neonatal and environmental dimensions including maternal interactive behavior.

The present study aimed to explore whether child social isolation due to the COVID-19 crisis was associated with toddlers' emotional and behavioral health (EBH) and whether this association was moderated by caregiving distress, during the second mandatory lockdown in Portugal. Participants included 315 toddlers and their primary caregivers.

The UCLA PTSD Reaction Index for DSM-5 (RI-5) is a developmentally appropriate and well recognized screening tool for the assessment of Post-Traumatic Stress Disorder (PTSD) in children and adolescents. The children/adolescent self-report version of the RI-5 has been thoroughly studied in very recent years, showing adequate psychometric properties. Despite such results, the utility of the parent/caregiver-report version, which also integrates the RI-5 system, remains to be explored.

Methods: Participants included 88 preterm-born children (<37 wk gestational age) and 44 full-term-born children (≥37 wk gestational age) aged 3 1/2 years and their parents. Mother-child and father-child dyads were observed during a structured interactive task.
Atlantic horse mackerel is one of the most commercially important species in Europe. It can reach a longevity of 30 years, with potential implications in lifespan mercury contamination. This study conducted along the Portuguese coast aimed at evaluating the total Hg content and tissue distribution, to determine the annual mercury bioaccumulation patterns and the associated risk for consumption.

To address this, we investigated the trait composition of fish communities in five regions along the Portuguese coast during 4 years. Northern regions were characterized by higher Chlorophyll-α and small-sized species with short lifespans.

Participants included 85 children born prematurely (gestational age <37 weeks) and their parents, assessed when children were 12, 24, and 42 months old. Observed overprotection was measured through the standardized observation of a parent-child interaction.

The relevance of the quality of parent-child interactions for child development has long been established. Nevertheless, research on beliefs about maternal sensitivity is still scarce, to an even greater extent in the context of child disability. This inquiry aimed to describe beliefs about sensitive parenting among mothers of children with developmental disabilities and to examine how those beliefs relate to sociodemographic factors and perceived stress.

Genetic variants that enhance immune reactivity may thus increase inflammatory and withdrawn reactions to stress. Here we investigated a functional polymorphism of Interferon Gamma gene (IFNG +874 T > A, rs2430561) as moderator of the relationship between mothers' distress exposure and children's withdrawn behavior at preschool age.

Mercury concentrations in muscle of Atlantic mackerel (Scomber scombrus), Atlantic chub mackerel (Scomber colias), European anchovy (Engraulis encrasicolus), Atlantic horse mackerel (Trachurus trachurus) and European pilchard (Sardina pilchardus) ranged from 0.003 to 0.

The oxytocinergic system is a primary biological system involved in regulating a child's needs for bonding and for protection from threats. It is responsive to social experiences in close relationships, though evidence across studies is not entirely consistent. Guided by previous literature, we investigated individual and environmental factors predicting and presumably affecting children's oxytocin (OT) response during mother-child interaction.

Fifty institutionalized infants and toddlers participated in this study. Child developmental functioning (i.

In this work, we performed a bacterial two-hybrid screening to search for RIC-protein interaction partners in As a result, the NA-binding rotein from tarved cells (Dps) was identified, and its potential interaction with RIC was tested by bacterial adenylate cyclase-based two-hybrid (BACTH) system, bimolecular fluorescence complementation, and pulldown assays. Using the activity of two Fe-S-containing enzymes as indicators of cellular Fe-S cluster damage, we observed that strains with single deletions of or have significantly lower aconitase and fumarase activities.

Despite its clinical relevance there is a lack of assessment tools for RAD based on the direct observation of child-caregiver interaction. Here we describe the development and validation of such a tool for use with preschool children, the Rating of Inhibited Attachment Disordered Behavior (RInAB).

Inhibited attachment disordered behavior (IADB) is characterized by difficulty in establishing an attachment relationship with a primary caregiver; is associated with persistent social and emotional problems; and is observed most frequently in contexts of pathological care such as institutional rearing. Here, we seek to enhance understanding of the conditions that give rise to IADB among institutionalized children by examining prior family experiences of neglect and deprivation and concurrent relational experiences at the institution. The sample is comprised of 146 children, between 36 and 78 months.

Under that premise, in situ experiments were run to test the effects of 2 °C temperature increase on the benthic communities in a seagrass bed and adjacent bare sediment, from a temperate European estuary. Temperature was artificially increased in situ and diversity and ecosystem functioning components measured after 10 and 30 days.
