Examining the dyadic effects of parental depression on parenting behaviors is important for understanding the dynamic impact of a family member’s negative emotions on parenting and family-based interventions. To clarify the interpersonal processes between parental depression and parenting within families, this study aimed to investigate the mutual influence of parental depression and parenting (warmth–reasoning and harshness–hostility) in one large sample of adolescent twins and their parents. A sample of 1387 Chinese families with adolescent twins was used. The actor–partner interdependence model (APIM) was used to examine the mutual influences. By examining the dyadic patterns with APIM, we found that depressive symptoms in mothers or fathers significantly influence their own and their partner’s parenting behaviors. The model comparisons found no significant difference in the partner effect between maternal and paternal depression. In the Chinese family system, depression in one parent influences not only their own parenting but also their partner’s parenting. Full article

The reproductive behavior and nest-building activity of the sand-dwelling goby Hazeus ammophilus were investigated to examine its nesting characteristics and to determine how and why this species builds radial structures around its nests. Field observations revealed that males spawned with multiple females in open muddy-sand bottoms, using bivalve shells or fallen leaves as spawning substrates. Males cared for eggs after spawning and repeatedly mated with multiple females, suggesting a male-territory-visiting polygamous mating system. A distinctive feature of this species was the presence of radial ditches extending from the nest. These ditches developed through repeated male behaviors of digging from the nest toward the surrounding area and sweeping accumulated sand out of the nest, resulting in a crater-like structure around the nest. These behaviors may contribute to cleaning and stabilizing the spawning substrate, and the resulting structures themselves may also be involved in female mate choice. Taken together, these findings indicate that H. ammophilus has evolved a flexible reproductive strategy, and nest-building behavior possibly adapted to unstable open sandy environments, highlighting the behavioral diversity and ecological plasticity within gobiid fishes.

Introduction: Paternal filicide is a rare and complex form of intrafamilial homicide, frequently associated with underlying psychopathology, interpersonal conflict, and psychosocial stressors. While maternal filicide has been more extensively studied, cases involving fathers—especially those employing multiple homicidal methods—remain significantly underrepresented in the forensic literature. This paper presents an unusual case of paternal filicide involving combined lethal methods, contextualized through a narrative review of comparable cases. Methods: A comprehensive forensic-pathological and psychiatric investigation was conducted following the homicide of an 8-year-old boy, killed by his father through a combination of asphyxiation and stabbing. A narrative literature review was performed using PubMed, Scopus, and Google Scholar, focusing on case reports and case series concerning paternal filicide. Particular attention was paid to homicidal methods, motivational dynamics, psychiatric comorbidities, and post-crime behavior. Results: The child’s body was found concealed in a building, in a bed storage drawer, with packing tape tightly wrapped around the mouth and nose and a kitchen knife embedded in the neck. No defensive wounds were observed, suggesting a sudden and unopposed assault, likely facilitated by the victim’s trust in the perpetrator. Autopsy findings revealed signs of asphyxiation and three stab wounds to the chin, neck, and thorax, involving vital structures such as the thyroid cartilage and heart. The father was found in a state of acute alcohol intoxication and subsequently convicted of intentional homicide. The motive appeared to be revenge-related, stemming from a highly conflictual marital separation. The literature review confirmed the predominance of retaliatory motives, frequent substance use, and post-crime suicidal behavior. However, the use of combined homicidal methods and the concealment of the body were found to be exceedingly rare. Conclusions: This case, combined with the literature review, highlights the need for deeper scientific exploration of paternal filicide. Comprehensive forensic and psychiatric assessments are essential to identify recurring situational patterns, motivational profiles, sociocultural contexts, and psychiatric vulnerabilities. These findings are critical not only for post-crime evaluations but also for the development of interdisciplinary prevention strategies targeting early warning signs and high-risk family dynamics.

Background: Late preterm delivery accounts for approximately 5% of all births. Although there is a growing body of literature recognizing that children born late preterm are at risk for mild neurodevelopmental issues, these children are often excluded from follow-up programs. From a preventive perspective, it could be useful to promote protective factors for child development. Among these, human milk feeding is highly recommended due to its advantages for child health and development. However, there is limited research on the complex interactions between late preterm birth, human milk feeding, and subsequent cognitive and emotional development. This paper aims to explore these interactions. Methods: This study focuses on late preterm children aged 8 to 12 years who are attending school. A trained psychologist conducted assessments of cognitive development using the Wechsler Intelligence Scale for Children-III (WISC-III). Additionally, the family pediatrician gathered neonatal and current growth data, while parents completed the Child Behavior Checklist 6–18 (CBCL) regarding their child’s emotional and behavioral profile. Results: A significant impact of early nutrition on children’s cognitive development was observed, with those fed human or formula milk scoring higher than those in the mixed milk group. Additionally, early feeding, high maternal and low paternal perception of externalizing difficulties significantly predicted children’s cognitive development. Conclusions: The study suggests the potential role of early nutrition and externalizing difficulties in the cognitive development of late preterm children at school age. Therefore, the inclusion of protective factors such as breastfeeding should be encouraged in future research. Full article

Background/Objectives: Timely initiation of antenatal care (ANC) services is crucial for ensuring maternal and fetal well-being. Despite the importance of ANC, research regarding its initiation remains limited in the Jazan region of Saudi Arabia, an area with notable adverse birth outcomes. Therefore, this study aimed to assess pregnant women’s initiation of ANC and identify associated factors and significant barriers for timely initiation. Methods: A cross-sectional study was conducted among 369 Saudi pregnant women in their third trimester attending ANC clinics in the Jazan region in 2024. A structured questionnaire was used to collect data. Andersen’s behavioral model of healthcare utilization provided the framework for the study. Descriptive statistics, chi-square tests, and binary logistic regression were used to analyze the data. Results: The majority of women (78.9%) initiated ANC in the first trimester. Higher maternal education was positively associated with early ANC initiation (aOR = 2.369, 95% CI: 1.154–4.901), whereas higher paternal education was negatively associated with early ANC initiation (aOR = 0.350, 95% CI: 0.175–0.699). When modeled independently, the positive association of higher maternal education was attenuated but was not significant, while the negative association of higher husband’s education remained the same. Those living more than three km from health facilities (aOR = 0.510, 95% CI: 0.276–0.941) and seeking care for reasons other than routine follow-up were less likely to initiate ANC early. Most women received essential services, but only 37.1% had ultrasound tests. Conclusions: While ANC initiation in Jazan showed promising trends, factors like geographical accessibility remain a significant barrier. Targeted interventions should address these identified barriers, which fall within predisposing, enabling, need, and external environmental factors. Further investigations of pregnant women’s familial decision-making and low ultrasound test utilization in relation to ANC are recommended. Full article

Background: Zero-dose children represent a critical challenge for achieving universal immunization coverage in sub-Saharan Africa. This study applies the Three Delays Model to examine multilevel factors associated with zero-dose children. Methods: We analyzed data from 30,500 children aged 12–23 months across 28 sub-Saharan African countries using demographic and health surveys (2015–2024). Zero-dose status was defined as not receiving the first dose of diphtheria–tetanus–pertussis vaccine. Multilevel logistic regression models examined individual-, community-, and country-level determinants. Results: Overall, zero-dose prevalence was 12.19% (95% confidence interval: 11.82–12.56), ranging from 0.51% in Rwanda to 40.00% in Chad. Poor maternal health-seeking behavior showed the strongest association (odds ratio (OR) 12.00, 95% credible interval: 9.78–14.55). Paternal education demonstrated clear gradients, with no formal education increasing odds 1.52-fold. Maternal empowerment factors were significant: lack of decision-making power (OR = 1.23), financial barriers (OR = 1.98), and no media access (OR = 1.32). Low community literacy and low country-level health expenditure were associated with increased zero-dose prevalence. Substantial clustering persisted at community (19.5%) and country (18.7%) levels. Conclusions: Zero-dose children concentrate among the most disadvantaged populations, with maternal health-seeking behavior as the strongest predictor. Immediate policy actions should integrate antenatal care with vaccination services, target high-parity mothers, eliminate financial barriers, and increase health expenditure to 15% of national budgets.

The Mediterranean soft-shell turtle (Trionyx triunguis) is classified as critically endangered by the IUCN. Effective conservation requires a clear understanding of its reproductive strategies and population structure. By combining mitochondrial DNA tandem repeat-region profiling with genome-wide SNP data obtained through 3RADseq, we gained high-resolution insights into the genetic composition and breeding behavior of Mediterranean populations. Our results revealed complex reproductive dynamics, including multiple paternity, sperm storage, and repeated nesting within a single season—strategies that enhance genetic diversity in small, fragmented populations. Using SNP-based kinship inference, we estimated the number of breeding females and identified full and half-sibling groups, offering a robust genomic framework for assessing population size and structure. Genetic similarity patterns highlighted moderate differentiation among Israeli river populations, suggesting some connectivity, while samples from Türkiye were clearly distinct, reflecting long-term geographic and genetic separation. This integrative approach provides a scalable, repeatable tool for long-term monitoring. The combined use of maternal and biparental markers enables detailed tracking of genetic diversity, breeding contributions, and demographic trends—key elements for designing informed, adaptive conservation strategies.

Background/Objectives: Childhood and adolescent obesity is a growing public health concern in Jordan, with implications for both physical and psychological well-being. While obesity’s physical effects are well-documented, less is known about its broader association with adolescents’ quality of life (QoL), particularly in Middle Eastern contexts. This study aimed to investigate the associations between weight status, psychosocial factors, and health-related quality of life (HRQOL) among Jordanian adolescents. This study aimed to investigate the associations between weight status, psychosocial factors, and HRQoL among Jordanian adolescents. Methods: A cross-sectional study was conducted with 719 adolescents (63.3% female) aged 11–18, recruited from public schools and pediatric clinics in three regions of Jordan. Data were collected using validated questionnaires assessing demographics, health behaviors, mental health (PHQ-9, GAD-7, SMFQ), and HRQoL (PedsQL 4.0). Structural equation modeling (SEM) was used to examine direct and indirect pathways predicting physical and psychological QoL. Results: Bullying emerged as a key mediator between weight status and QoL, particularly for physical well-being. Depression and anxiety were significant predictors of poorer psychological QoL. Positive school experience, academic performance, physical activity, and paternal education were positively associated with QoL. Nutritional habits were inversely associated with anxiety levels. Model fit indices supported the adequacy of both the physical and psychological QoL models. Conclusions: The findings highlight the interconnected relationship of weight-related stigma, school environment, and lifestyle behaviors on adolescent well-being. Multi-component, school-based interventions targeting bullying, physical activity, and mental health literacy may be effective in improving QoL in this population. Full article

Background/Objectives: Food technology neophobia (FTN), defined as the reluctance to accept or consume foods produced with novel or emerging food technologies, represents a psychological barrier to the adoption of sustainable and innovative dietary practices. This cross-sectional study investigated the prevalence of food technology neophobia and its associated factors among Italian university students. Methods: A total of 1788 undergraduates from 13 universities completed a validated online questionnaire between February and October 2024. The instrument included the Food Technology Neophobia Scale (FTNS), environmental attitude items, and demographic and dietary questions. Results: The mean FTNS score was 51.2 ± 14.0, suggesting moderate levels of neophobia. Multivariate logistic regression identified several factors inversely associated with neophobia: male gender (OR = 0.73, p = 0.003), paternal university education (OR = 0.73, p = 0.024), studying in Northern Italy (OR = 0.64, p < 0.001), dietary supplement use (OR = 0.74, p = 0.003), and pro-environmental attitudes (OR = 0.97, p < 0.001). Conversely, being a commuter student was associated with increased neophobia (OR = 1.29, p = 0.031). Conclusions: These findings highlight the influence of socio-demographic, behavioral, and attitudinal factors on the acceptance of new food technologies. Tailored strategies are recommended to address FTN in specific subgroups, particularly among female, commuter, and Southern Italian students, to enhance receptivity to food innovation and support sustainable dietary transitions.

Autism Spectrum Disorder (ASD) affects an estimated prevalence of 1 in 31 children but the cause in most cases is unknown. Human and animal studies have linked ASD to Folate Receptor Alpha Autoantibodies (FRAAs). Our previous studies demonstrated that FRAAs are more common, on average, in families with children with ASD. This study reanalyzed data from a previous study which included 82 children diagnosed with ASD, 53 unaffected siblings, 70 mothers, 65 fathers, and 52 typically developing controls who did not have a history of ASD in their family. This study investigates the association of FRAA titers with ASD risk factors and explores the relationship of FRAA titers across generations. Several known risk factors for ASD, including multiplex ASD families, multiple birth pregnancies, and increased maternal and paternal ages at birth, were related to offspring FRAA titers. Multiplex ASD families demonstrated higher FRAA titers. Significant correlation were found between maternal and offspring blocking FRAA titers. FRAA titers increased across generations, although the increase in blocking FRAA titers was only seen in multiplex families. The proband with ASD showed higher blocking but not higher binding, FRAA titers compared to their non-affected siblings. Paternal FRAA titers are associated with several measures of offspring behavior and cognitive development. This research highlights the potential transgenerational transmission of FRAAs and their role in ASD. This supports the notion that heritable non-genetic factors may be important in the etiology of ASD and that FRAAs may demonstrate anticipation (worsening across generations), especially in multiplex families. FRAAs may provide one example of the possibility that susceptibility to autoimmune processes may contribute to disrupted brain development and function in ASD. Full article

Background/Objectives: Breastfeeding is key to maternal and child health, but adherence to WHO recommendations varies worldwide and is influenced by several maternal and paternal factors. In this study, we aim to describe the prevalence of breastfeeding practices and adherence to WHO guidelines among women, and to explore the maternal and paternal characteristics associated with these practices. Methods: Data were obtained from the “MAMI-MED” cohort, which included women enrolled during the first trimester of pregnancy at ARNAS Garibaldi Nesima in Catania (Italy). Breastfeeding practices and parental characteristics were assessed through interviews conducted at 12- and 24-month follow-ups. Results: The analyses involved 1312 women enrolled between December 2020 and October 2023. Mothers who breastfed, particularly those who exclusively breastfed for the first six months, showed a more favorable socioeconomic profile. Women with a medium (OR = 1.781; 95% CI: 1.258–2.521; p = 0.001) and high level of education (OR = 3.892; 95% CI: 2.255–6.718; p < 0.001), as well as those who had a spontaneous delivery (OR = 1.461; 95% CI: 1.090–1.958; p = 0.011), were more likely to breastfeed. Similarly, adherence to WHO recommendations was higher among women with a medium (OR = 2.144; 95% CI: 1.339–3.433; p = 0.002) and high education levels (OR = 2.611; 95% CI: 1.489–4.580; p < 0.001), non-smokers (OR = 2.256; 95% CI: 1.158–4.395; p = 0.017), and those with adequate gestational weight gain (OR = 1.506; 95% CI: 1.035–2.189; p = 0.032). Conclusions: Sociodemographic and behavioral factors, particularly maternal education, smoking status, mode of delivery, and gestational weight gain, significantly influence breastfeeding practices and adherence to WHO recommendations. These findings highlight the importance of targeted interventions to support breastfeeding, especially among women with less favorable socioeconomic profiles. Full article

Cocaine use remains a major public health concern, with rising global prevalence and a well-established profile of neurotoxicity and addictive potential. While the central nervous system has been the primary focus of cocaine research, emerging evidence indicates that cocaine also disrupts male reproductive physiology. In the testis, cocaine alters the endocrine microenvironment, induces cell-specific damage, and disrupts spermatogenesis. Cocaine also interferes with epigenetic programming in germ cells and mature sperm, potentially leading to heritable epimutations. Epidemiology data reveal that approximately two-thirds of regular cocaine users are males of reproductive age, and preclinical models have documented numerous behavioral and molecular alterations in their offspring, often linked to paternal cocaine exposure—such as increased drug resistance or vulnerability, altered anxiety-like behavior, impaired learning/memory, disrupted social behaviors, and shifts in neural circuitry and gene expression in reward-related brain regions. This review aims to integrate findings from studies that have independently examined testicular dysfunction, germline epigenetic reprogramming, and offspring outcomes, offering a unified perspective on their potential interconnections and highlighting future directions for research in the field of epigenetic inheritance.

The term chromosomal imprinting was introduced to denote the parent-of-origin-dependent behavior of chromosomes in the fungus gnat originally named Sciara coprophila (current taxonomic name is Bradysia coprophila). Such behavior is observed in Sciara coprophila embryos, where paternal X chromosomes (X_p) are specifically eliminated during the 7th–8th cleavage divisions. Elimination is regulated by a controlling element (CE) that has been mapped to heterochromomere II (H2) within the sub-telomeric short arm of polytene X chromosomes. Here, using a combination of a new Sciara genome assembly, along with ChIP-Seq and MeDIP analyses, we show that a 1.2 Mb region within the CE locus has a repressive epigenetic signature that is characterised by enrichments of H3K9me3, H4K20me3 and 5′-methyl cytosine (5meC). These data provide evidence for a model where the H3K9me3/HP1/H4K20me3 pathway operates to assemble a heterochromatin-like complex at the CE that renders it silent on X_p chromosomes that are not eliminated. In this regard, our findings support the idea that the H3K9me3/HP1/H4K20me3 pathway represents the most evolutionarily conserved mechanism linked to chromosomal imprinting in animals. Full article

Background/Objectives: Parental mental representations play a crucial role in shaping early parent–child relationships, particularly during the perinatal period. These internal models influence caregiving behaviors, emotional attunement, and the intergenerational transmission of attachment. The present systematic review aims to address this gap by examining the nature of both maternal and paternal mental representations in the perinatal period (involving pregnancy and the first postnatal time), with a particular emphasis on reflective functioning, and by outlining the variables that are influenced by these representations. Methods: Following PRISMA guidelines, eligible peer-reviewed studies were identified through a comprehensive literature search of major scientific databases (Scopus, Web of Science, PsychArticle/PsycInfo). Qualitative assessment and detailed description were carried out. Results: In total, 28 studies were selected and analyzed. Findings reveal that while representations tend to organize around shared psychological domains—such as expectations regarding the child, parental identity, and the anticipated relationship—there is significant heterogeneity in how these are conceptualized and measured across studies. Risk factors such as maternal depression, low social support, and adverse life experiences were consistently linked to disengaged or distorted representations, whereas balanced representations were associated with greater RF, emotional availability, and protective relational contexts. Conclusions: Overall, the review highlights the clinical relevance of assessing parental mental representations and RF during the perinatal period, suggesting that early, targeted interventions may enhance parental sensitivity and promote secure parent–infant bonds. Future research should adopt integrated theoretical models, include diverse family configurations, and evaluate the efficacy of preventive programs that support reflective and adaptive representations.

Background/objectives: Optimal infant nutrition, particularly exclusive breastfeeding for the first 6 months, is crucial for both immediate and long-term health. The early years of life are essential for brain development due of the rapid maturation of social, emotional, cognitive and motor capacities. While benefits of breastfeeding are well established, its long-term impact on neurodevelopment remains underexplored. This study investigates the relationship between breastfeeding duration and neurodevelopment outcomes at 5 years of age. Methods: This prospective cohort study followed 92 term-born infants in Varna, Bulgaria (2017–2024). Parents provided informed consent and completed questionnaires regarding demographic characteristics, feeding practices and atopic diseases. At 5 years of age, children were assessed using the Neurodevelopmental Test for Five-Year-Olds. Results: Feeding practices differed significantly across groups (p < 0.001), with exclusive breastfeeding more prevalent among children breastfed for longer. At 5 years, significant differences were observed in language development (p = 0.037) and behavioral outcomes (p = 0.001). A linear regression model for behavioral outcomes (F = 2.29, p = 0.011, R² = 0.297) showed that breastfeeding for 6–12 months was associated with more favorable behavior (Estimate = −5.88, p = 0.026), compared to less than 6 months. In contrast, paternal secondary education (Estimate = 3.58, p = 0.048) compared to higher education and mixed ethnicity (Estimate = 12.55, p = 0.023) compared with Bulgarian ethnicity were associated with poorer behavioral outcomes (Estimate = 3.58, p = 0.048). Conclusions: Breastfeeding for 6 to 12 months may be associated with improved behavioral development, and to a lesser extent, language outcomes at age five. However, these domain-specific associations were not consistently supported across all statistical methods and should be interpreted with caution. Neurodevelopment is influenced by a complex interplay of nutritional, social and environmental factors. Longitudinal studies are needed to clarify the long-term effects of breastfeeding duration on neurodevelopment. Full article
