RESUMEN

Exposure to risk factors and adversity may cause immediate, and sometimes prolonged, psychological symptoms in adolescents. Identifying universal and specific risk factors in a particular context and examining their cumulative effects is crucial for understanding the mechanisms underlying psychological symptoms and informing about strategies for intervention. Using concurrent measures, the current study aimed to examine the role of armed conflict experiences and cumulation of other risk factors (e.g., maternal psychological symptoms, socioeconomic indicators) in predicting adolescent psychological symptoms in an underresearched community. The sample included 161 adolescents (54.7% female) aged 11-14 years (M = 12.36, SD = 1.27) and their mothers living in the east of Turkey. The cumulative risk index was calculated by summing the standardized scores of the corresponding factors. Hierarchical multiple regression analyses were conducted to predict internalizing and externalizing symptoms among adolescents by introducing demographic variables (age, gender) in the first step, armed conflict experiences and cumulative risk in the second step, and their interaction in the final step. Results showed that the levels of internalizing and externalizing symptoms were predicted by gender, armed conflict experience and cumulative risk. Being a girl was associated with higher levels of internalizing symptoms and lower levels of externalizing symptoms. Higher levels of internalizing and externalizing symptoms were predicted by exposure to armed and cumulative risk. After controlling for other factors, the interaction of armed conflict experience and cumulative risk significantly predicted externalizing, but not internalizing symptoms. These findings suggested that cumulative risk was a stronger predictor of psychological symptoms, and further amplified the strength of the association between armed conflict experiences and externalizing symptoms. These findings can be used in the formulation of intervention strategies and policies to promote psychological well-being in adolescents living in armed conflict zones under multiple risks.

RESUMEN

This study investigates the role of socioeconomic adversity and armed conflict in executive function (EF), theory of mind (ToM) and empathy in a rarely studied group, children living in eastern Turkey. The data were collected from 115 children (60 girls) aged 39 to 95 months (M = 68.22, SD = 14.62). Results revealed that children's performance was low in the EF and ToM tasks, and high in the empathy task. In path analysis, controlling for age, armed conflict experience predicted lower EF (ß = - 0.15) and higher empathy (ß = 0.21), and socioeconomic adversity predicted lower ToM (ß = 0.20). These findings contribute to our knowledge on cognitive and emotional development of children who live in such disadvantaged contexts.

RESUMEN

BACKGROUND: Pathogenic missense variants in PRKAG2, the gene for the gamma 2 regulatory subunit of adenosine monophosphate-activated protein kinase (AMPK), cause severe progressive cardiac disease and sudden cardiac death, named PRKAG2 cardiomyopathy. In our previous study, we reported a E506K variant in the PRKAG2 gene that was associated with this disease. This study aimed to functionally characterize the three missense variants (E506K, E506Q, and R531G) of PRKAG2 and determine the possible effects on AMPK activity. METHODS: The proband was clinically monitored for eight years. To investigate the functional effects of three missense variants of PRKAG2, in vitro mutagenesis experiments using HEK293 cells with wild and mutant transcripts and proteins were comparatively analyzed using quantitative RT-PCR, immunofluorescence staining, and enzyme-linked immunosorbent assay. RESULTS: In the long-term follow-up, the proband was deceased due to progressive heart failure. In the in vitro experimental studies, PRKAG2 was overexpressed after 48 h of transfection in three mutated cells, after which the expression levels of PRKAG2 were regressed to the level of wild-type cells in 3-weeks stably transformed cells, except for the cells with E506K variant. E506K, E506Q, and R531G variants had caused a reduction in the AMPK activity and resulted in the formation of cytoplasmic glycogen deposits. CONCLUSION: Three missense variants that alter AMPK activity affect a residue in the CBS4 domain associated with ATP/AMP-binding. Detailed information on the influence of PRKAG2 pathogenic variants on AMPK activity would be helpful to improve the treatment and management of patients with metabolic cardiomyopathy.

RESUMEN

Using a between-groups design and random assignment, this study examined 214 Turkish children's (M = 11.66 years) mindreading and general reasoning about in-group members (Turks), similar out-group members (Syrians within Turkey) and dissimilar out-group members (Northern Europeans). Children heard four mindreading and four general reasoning stories with in-group or out-group members as targets. Whereas children's general reasoning about three groups was equivalent, accuracy of mental state inferences differed by target with more accurate mindreading of in-group targets compared to both sets of out-group targets. In this Turkish sample, mindreading of Syrian targets was the least accurate. Prejudice and perceived realistic threat predicted lower mindreading. These findings have important implications for understanding how similarity and intergroup processes play a role in children's mindreading.

RESUMEN

Humans are social beings, and acts of prosocial behavior may be influenced by social comparisons. To study the development of prosociality and the impact of social comparisons on sharing, we conducted experiments with nearly 2500 children aged 3-12 years across 12 countries across five continents. Children participated in a dictator game where they had the opportunity to share up to 10 of their stickers with another anonymous child. Then, children were randomized to one of two treatments. In the "shared a little" treatment children were told that another child from their school had shared 1 sticker, whereas in the "shared a lot" treatment children were told that another child from their school had shared 6 stickers in the same game. There was a strong increase in baseline sharing with age in all countries and in both treatments. The "shared a lot" treatment had a positive treatment effect in increasing sharing overall, which varied across countries. However, cross-cultural comparisons did not yield expected significant differences between collectivist and individualist countries. Our results provide interesting evidence for the development of sharing behavior by age across the world and show that social information about the sharing of peers is important for children's decision making.

RESUMEN

BACKGROUND: Severe congenital neutropenia is a rare disease, and autosomal dominantly inherited ELANE mutation is the most frequently observed genetic defect in the registries from North America and Western Europe. However, in eastern countries where consanguineous marriages are common, autosomal recessive forms might be more frequent. METHOD: Two hundred and sixteen patients with severe congenital neutropenia from 28 different pediatric centers in Turkey were registered. RESULTS: The most frequently observed mutation was HAX1 mutation (n = 78, 36.1%). A heterozygous ELANE mutation was detected in 29 patients (13.4%) in our cohort. Biallelic mutations of G6PC3 (n = 9, 4.3%), CSF3R (n = 6, 2.9%), and JAGN1 (n = 2, 1%) were also observed. Granulocyte colony-stimulating factor treatment was given to 174 patients (80.6%). Two patients died with infectious complications, and five patients developed myelodysplastic syndrome/acute myeloblastic leukemia. The mean (± mean standard error) follow-up period was 129.7 ± 76.3 months, and overall survival was 96.8% (CI, 94.4-99.1%) at the age of 15 years. In Turkey, severe congenital neutropenia mostly resulted from the p W44X mutation in the HAX1 gene. CONCLUSION: In Turkey, mutation analysis should be started with HAX1, and if this is negative, ELANE and G6PC3 should be checked. Because of the very high percentage of consanguineous marriage, rare mutations should be tested in patients with a negative mutation screen.

RESUMEN

A concern for fairness is a fundamental and universal element of morality. To examine the extent to which cultural norms are integrated into fairness cognitions and influence social preferences regarding equality and equity, a large sample of children (N 2,163) aged 4-11 were tested in 13 diverse countries. Children participated in three versions of a third-party, contextualized distributive justice game between two hypothetical recipients differing in terms of wealth, merit, and empathy. Social decision-making in these games revealed universal age-related shifts from equality-based to equity-based distribution motivations across cultures. However, differences in levels of individualism and collectivism between the 13 countries predicted the age and extent to which children favor equity in each condition. Children from the most individualistic cultures endorsed equitable distributions to a greater degree than children from more collectivist cultures when recipients differed in regards to wealth and merit. However, in an empathy context where recipients differed in injury, children from the most collectivist cultures exhibited greater preferences to distribute resource equitably compared to children from more individualistic cultures. Children from the more individualistic cultures also favored equitable distributions at an earlier age than children from more collectivist cultures overall. These results demonstrate aspects of both cross-cultural similarity and divergence in the development of fairness preferences.

RESUMEN

ROR-alpha is a nuclear receptor, activity of which can be modulated by natural or synthetic ligands. Due to its possible involvement in, and potential therapeutic target for atherosclerosis, we aimed to identify ROR-alpha target genes in monocytic and endothelial cell lines. We performed chromatin immunoprecipitation (ChIP) followed by tiling array (ChIP-on-chip) for ROR-alpha in monocytic cell line THP1 and endothelial cell line HUVEC. Following bioinformatic analysis of the array data, we tested four candidate genes in terms of dependence of their expression level on ligand-mediated ROR-alpha activity, and two of them in terms of promoter occupancy by ROR-alpha. Bioinformatic analyses of ChIP-on-chip data suggested that ROR-alpha binds to genomic regions near the transcription start site (TSS) of more than 3000 genes in THP1 and HUVEC. Potential ROR-alpha target genes in both cell types seem to be involved mainly in membrane receptor activity, signal transduction and ion transport. While SPP1 and IKBKA were shown to be direct target genes of ROR-alpha in THP1 monocytes, inflammation related gene HMOX1 and heat shock protein gene HSPA8 were shown to be potential target genes of ROR-alpha. Our results suggest that ROR-alpha may regulate signaling receptor activity, and transmembrane transport activity through its potential target genes. ROR-alpha seems also to play role in cellular sensitivity to environmental substances like arsenite and chloroprene. Although, the expression analyses have shown that synthetic ROR-alpha ligands can modulate some of potential ROR-alpha target genes, functional significance of ligand-dependent modulation of gene expression needs to be confirmed with further analyses.

RESUMEN

There is a well-established relationship between theory of mind (ToM) and executive function (EF) during the preschool years. However, less is known about the concurrent and longitudinal relations between EF and specific tasks tapping different aspects of ToM. The current study investigated the ToM-EF relationship across 1 year in 3- to 5-year-old Turkish children using the ToM battery of Wellman and Liu (2004), which measures understanding of diverse desires (DD), diverse beliefs (DB), knowledge access (KA), contents false belief (CFB), explicit false belief (EFB), and hidden emotion (HE). This battery has not yet been used in its entirety to test the predictive relations between ToM and EF. We used peg-tapping and day-night tasks to measure EF. Our sample comprised 150 Turkish preschool children (69 girls) aged 36-60 months at Time 1 (T1) and 49-73 months at Time 2 (T2). Using the ToM composite with all six tasks, when child's age, receptive language, and T1 ability level (EF or ToM) were controlled, T1 EF significantly predicted T2 ToM, whereas T1 ToM did not predict T2 EF. Among DD, DB, KA, false belief understanding (FBU: the composite score of CFB and EFB), and HE, only KA and FBU were significantly associated with EF at T1 and T2. Further regression analyses showed that KA did not have a predictive relationship with EF. Instead, FBU drove the predictive EF-ToM relationship across time. Thus, in Turkish children, earlier EF predicts later ToM, but especially the FBU component, in this well-validated battery.

RESUMEN

Childhood obesity/overweight (OB/OW) displayed a rapid increase and high prevalence in the last few decades in preschool-aged children, which raised health concerns across the world and motivated researchers to investigate the factors that underlie childhood obesity. The current study examined parenting styles and child-feeding practices as potential predictors for OB/OW in preschool children, controlling for child's temperament, which has been shown to be linked with OB/OW. The sample included 61 normal weight (NW) and 61 obese/overweight (OB/OW) Turkish pre-schoolers (M age = 62.2 months; SD = 7.64, range = 45-80 months). Parenting styles (authoritarian, authoritative), child-feeding practices (restriction, pressure to eat, monitoring), and child's temperament (negative affectivity) were measured with mothers' reports. Results showed that authoritarian parenting and maternal pressure to eat were the two parenting variables that significantly predicted child's weight status; the odds of being OB/OW was 4.71 times higher in children whose mothers used higher authoritarian parenting style, and was 0.44 times lower when mothers pressured their child to eat. These findings suggest that understanding the unique role of different aspects of parenting in the risk of early OB/OW status of children would be important in developing more effective interventions from early years in life.

RESUMEN

RORα is a member of nuclear receptor superfamily of transcription factors, which has a vital role in the regulation of various physiological processes. Cholesterol is a known ligand of RORα and is one of the key components that take part in cardiovascular diseases such as atherosclerosis. Therefore, it is possible that RORα might have a role in the development of atherosclerosis. To test this hypothesis, we investigated the presence of novel RORα response elements (ROREs) located in the promoter of CYP19A1, MIF and ABCA1 genes. Briefly, the occupancy of RORα in the promoter regions of these genes was demonstrated in THP-1 and HUVEC cell lines by ChIP analysis. In order to modulate RORα activity, THP-1 and HUVEC cells were treated with specific RORα ligands (CPG 52608 and SR1001) and then the expression levels of target genes were analysed. In the next step, we tested whether RORα activity in THP-1 macrophages was influenced by the presence of simvastatin, a cholesterol lowering drug. We found that in the presence of simvastatin the expression of the investigated target genes were down regulated and that this regulation was partially prevented by CPG 52608 and SR1001. Results of this study suggest that CYP19A1, MIF and ABCA1 are the direct target genes of RORα. In conclusion, it is important to demonstrate that certain genes involved in the development of atherosclerosis could be modulated by an inducible transcription factor. Therefore, these results offer a potential therapeutic approach for the treatment of atherosclerosis.

RESUMEN

Morality is an evolved aspect of human nature, yet is heavily influenced by cultural environment. This developmental study adopted an integrative approach by combining measures of socioeconomic status (SES), executive function, affective sharing, empathic concern, theory of mind, and moral judgment in predicting sharing behavior in children (N = 999) from the age of 5 to 12 in five large-scale societies: Canada, China, Turkey, South Africa, and the USA. Results demonstrate that age, gender, SES, culture, and social cognitive mechanisms explain over 20% of the variance worldwide in children's resource allocation. These findings are discussed in reference to standard cultural comparisons (individualist/collectivist), as well as the degree of market integration, and highlight continuities and discontinuities in children's generosity across urban contexts.

RESUMEN

In Turkey, responsive behaviors toward kin are expected from children. Despite this, we know little about the factors that influence young Turkish children's prosocial behaviors. The goal was to explore how temperament and parenting are related to children's prosocial development in Turkey. A total of 293 Turkish children (Mage  = 49 months; 48.12% females) were followed up for 3 years. Mothers completed measures of their child's prosocial behaviors, as well as measures of their warmth, inductive reasoning, and the child's approach and reactivity. Maternal warmth predicted children's reactivity, and maternal induction predicted children's sociability. Children's reactivity was inversely related to children's helping behavior and sociability was related to more prosocial behavior. Maternal warmth had indirect links with helping through lessening children's reactivity.

RESUMEN

Although studies have so far investigated social dominance orientation (SDO) in relation to its association with prejudice and discrimination toward outgroups, it is not known whether SDO's link with poor intergroup relations might be underlined by specific socio-cognitive factors such as reduced mind-reading motivation (MRM) and poor mind-reading performance. The present study tested whether endorsement of SDO is associated with decreased MRM and mind-reading accuracy toward both ingroup and outgroup targets. We randomly assigned one hundred and 20 Turkish university students (Mage = 22.02) into two target groups for mind-reading, Turkish ingroup (N = 60) and Syrian outgroup (N = 60), and asked them to infer minds of either ingroup or outgroup members depending on their target group. Participants also reported their level of MRM and SDO through questionnaires. When the target was a Turkish ingroup member, SDO negatively and directly predicted mind-reading, when the target was an outgroup member, however, higher SDO indirectly predicted lower mind-reading through reduced MRM. These results pointed that favoring intergroup hierarchies relates to poor understanding of others' mental states although the mechanism of the relation changes depending on the group membership of the target.

RESUMEN

OBJECTIVE: To evaluate the origin and ultrastructure of the coarse granules in the perivitelline space (PVS) of oocytes of a group of couples attending assisted reproduction treatment. METHODS: The ultrastructure of five oocytes with coarse granulues in the PVS obtained from three patients were evaluated by transmission electron microscopy (TEM). The influence of the ovulation induction regimen on the formation of granules in the PVS of the oocytes of 214 couples and the developmental capacity of these oocytes presenting granules in the PVS was analyzed retrospectively. RESULTS: In TEM analysis, the microvilli structure was irregular, short, and loosely scattered through the oolemma in the oocytes presenting coarse granules in the PVS. Furthermore, dense lipid droplets were identified within the PVS and the surrounding cumulus cells. In retrospective analysis, the number of oocytes with coarse granules in the PVS was positively correlated with the duration of antagonist administration (r=0.23, p=0.013). Regardless of the type of granule, the presence of coarse or moderately coarse granules in the PVS was positively correlated with low-quality embryos on D3 (r=0.29, p=0.005) and the total number of arrested embryos up to D3 (r=0.33, p<0.001). Furthermore, the presence of coarse granules in the PVS severely exacerbated miscarriage rates. CONCLUSIONS: Our findings suggest that the presence of especially coarse granules in the PVS is correlated with the reduction of further embryonic developmental capacity in post-implantation stages of embryonic development, indicating a negative impact from aggressive ovulation induction protocols on developing oocytes.

RESUMEN

The scope of cell-free DNA (cfDNA) testing was expanded to the genome, which allowed screening for rare chromosome anomalies (RCAs). Since the efficiency of the test for RCAs remains below the common aneuploidies, there is a debate on the usage of expanded tests. This study focuses on the confirmatory and follow-up data of cases with positive cfDNA testing for RCAs and cases with screen-negative results in a series of 912 consecutive cases that underwent invasive testing following cfDNA testing. Chorion villus sampling (CVS), amniocentesis (AS), fetal blood sampling, and term placenta samples were investigated using classical cytogenetic and molecular cytogenetic techniques. Out of 593 screen-positive results, 504 (85%) were for common aneuploidies, 40 (6.7%) for rare autosomal trisomies (RATs), and 49 (8.3%) for structural chromosome anomalies (SAs). Of the screen-positives for RATs, 20 cases were evaluated only in fetal tissue, and confined placental mosaicism (CPM) could not be excluded. Among cases with definitive results (n = 20), the rates of true positives, placental mosaics, and false positives were 35%, 45%, and 10%, respectively. Among screen-positives for SAs, 32.7% were true positives. The confirmation rate was higher for duplications than deletions (58.3% vs. 29.4%). The rate of chromosomal abnormality was 10.9% in the group of 256 screen-negatives with pathological ultrasound findings. This study provides further data to assess the efficiency of expanded cfDNA testing for RATs and SAs. The test efficiency for cfDNA seems to be higher for duplications than for deletions, which is evidence of the role of expert ultrasound in identifying pregnancies at increased risk for chromosome anomalies, even in pregnancies with screen-negatives. Furthermore, we discussed the efficiency of CVS vs. AC in screen-positives for RATs.

RESUMEN

Maternal control is a major dimension of parenting and has different meanings, practices, and potential consequences across cultures. The present study aimed to identify and compare mothers' conceptualizations of parenting control across four cultures to reveal a more nuanced understanding regarding the meaning and practices of control: European American, Chinese immigrant, Korean immigrant, and Turkish. Using a semistructured open-ended interview, 100 European American, 102 U.S. Chinese immigrant, 103 U.S. Korean immigrant, and 109 Turkish mothers of preschool-aged children reported the ratings of importance, specific reasons, and strategies for exerting control over their children in daily life. Results revealed both shared and unique conceptualizations of maternal control across four cultures. Specifically, all mothers reported that it is important to express maternal control over their children in order to set behavioral norms/standards, maintain child safety, support social relations and respect for others, provide guidance, and guide moral development. Moreover, mothers discussed utilizing nonphysical punishment, setting and maintaining rules, reasoning/negotiating, consistency, physical punishment and verbal control, showing parents' serious/stern attitude, correction, and psychological control forms of control. However, the levels at which mothers emphasize the different reasons and strategies varied across cultures, reflecting culturally emphasized values. The findings of the present study further enrich our understanding of the complexities of maternal control across cultures. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

RESUMEN

Children living in armed conflict zones are often exposed to political violence and other risk factors that may be caused or exacerbated by the conflict, such as poverty and family violence. If left untreated, these experiences may cause psychological problems throughout life. This study investigated the psychological well-being of children living in the low-intensity armed conflict zone in Turkey in relation to their adverse experiences. We collected data from 409 caregivers for their children (236 girls) aged 5.5 to 18 years (mean [M] = 11.50, standard deviation [SD] = 3.65). Caregivers provided information regarding their children's emotional and behavioral problems (internalizing, externalizing, and total problems; posttraumatic stress symptoms [PTSS]), income, family violence, and armed conflict experiences. Caregivers reported moderate levels of problems among children. The prevalence of borderline/clinical (T ≥ 60) scores was 14.3% for internalizing, 12.6% for externalizing, and 14% for total problems and 7.9% for PTSS. Notably, almost all families resided in extreme poverty. The prevalence of family violence was 36%. Children were frequently exposed to conflict-related events. Hierarchical regressions showed that after controlling for the role of demographic variables and other risk factors, income predicted total problem level (ß = -.10), and family violence (ßs = .17 to .26) and armed conflict (ßs = .13 to .20) experiences predicted internalizing, externalizing, and total problems and PTSS levels. Our findings suggest that family violence and armed conflict pose a significant risk to children's psychological well-being and inform intervention strategies and policy decisions to promote welfare in such disadvantaged contexts.

RESUMEN

Analyses of the present data are reported in the article "Crossing Boundaries: A Pilot Study of Maternal Attitudes about Child Maltreatment in Nine Countries" [8]. Data were collected during home visits using the Maltreatment Q-Sort (MQS). A total of 466 mothers from nine different countries gave their opinion about child maltreatment by sorting 90 cards with parenting behaviors taken from the literature that reflect four types of child maltreatment, into 9 evenly distributed stacks (with 10 cards each) from least to most harmful for the child. This data article provides an overview of the content of the 90 items, which type of maltreatment they reflect, and the source of the items. The percentage of mothers labelling each of the MQS items as maltreatment is also presented. In addition, instructions are included about the administration of the MQS as well as data-entry and analyses of Q-sort data, accompanied by example datasets and syntaxes. This can serve as a manual for researchers interested in using Q-sort data.

RESUMEN

BACKGROUND: Definitions of child maltreatment vary widely between studies, and even more so between different cultural contexts. OBJECTIVE: In this pilot study, we examine between-country variations in maternal notions about what constitutes child maltreatment. PARTICIPANTS AND SETTING: The sample consisted of 466 mothers recruited in Chile, China, Greece, Iran, the Netherlands, Portugal, South Africa, Turkey, and Uruguay. METHODS: All mothers completed a new Q-sort measure, ranking 90 parenting behaviors linked to subtypes of maltreatment (emotional neglect, emotional abuse, physical neglect, and physical abuse) from least to most detrimental to child development. RESULTS: Between-country agreement regarding the harmfulness of the parenting behaviors was high (r = .45), but there were different patterns of reported harmfulness of subtypes of maltreatment (although driven mostly by deviating patterns in the South African sample). Further, there were significant country effects on the number and type of behaviors labeled as maltreatment (pƞ2 = .15), and the number of items labeled as requiring intervention (pƞ2 = .19). CONCLUSIONS: Variations in conceptions of maltreatment need to be studied in larger more representative samples and taken into account in the assessment and treatment of child maltreatment across cultures.
