The present study examines the impact of child and family risk factors on service access for youth and families in a school-based system of care. Regression analyses examined the relationships between risk factors and services recommended, services received, and dosage of services received. Logistic regression analyses examined the relationship between risk factors and whether or not youth received specific types of services within the system of care. Results revealed that youth with a personal or family history of substance use had more services recommended than youth without these risk factors, while youth with a family history of substance use received more services. Youth with a history of substance use received a significantly higher dosage of services overall. Finally, history of family mental illness was associated with receiving mental health and operational services (e.g., family advocacy, emergency funds). Implications and limitations are discussed.

The aims of the present study were to investigate satisfaction with verbal communication among the disabled elderly and their family caregivers; and to find the significantly influential factors of satisfaction with verbal communication. The subjects were 85 disabled elderly and 85 family caregivers. For the disabled elderly, satisfaction with verbal communication, demographic, and physical factors were examined using an interview survey. For the caregivers, satisfaction with verbal communication, demographic factors, and some factors related caregiving were examined using a self-administered questionnaire. In the disabled elderly, 82.4% were satisfied with their verbal communication while 55.3% of family caregivers were satisfied. Satisfaction with verbal communication between the disabled elderly and their caregivers showed low agreement (kappa = 0.17). Bivariate analysis revealed that satisfaction with verbal communication of the disabled elderly was significantly related to ADL (p < 0.01), dysphagia risk (p < 0.05), and ability of comprehension (p < 0.05) while satisfaction with verbal communication of caregivers was significantly related to the gender of the disabled elderly and caregivers' burden. Furthermore, multiple regression analysis showed that the factor most related to satisfaction with verbal communication for the disabled elderly was ability of comprehension (p value = 0.032, odds ratio = 2.960), and the most related factor for their caregivers was the burden evaluated by J-ZBI_8 (p value = 0.004, odds ratio = 0.842). These results suggest that satisfaction with verbal communication of the disabled elderly disagrees with that of the family caregivers, and that some related factors for the disabled elderly are different from those in their family caregivers.

The purpose of this study was to assess the mediating role of depression in three different relationships: (a) sibling bullying and peer victimization, (b) mothers' power-assertive parenting and peer victimization, and (c) fathers' power-assertive parenting and peer victimization. Results from 242 Latino middle school adolescents from a large southwestern city bordering Mexico revealed that both boys' and girls' peer victimization were related to familial factors and depression. Regression analyses for boys revealed that depression mediated three relationships: (a) sibling bullying and peer victimization, (b) mothers' power-assertive parenting and peer victimization, and (c) fathers' power-assertive parenting and peer victimization. Depression also mediated the relationship between fathers' power-assertive parenting and girls' victimization by peers. The findings support the development of family-based interventions for peer victimization that include curriculum addressing depression.

Suicide is a leading cause of death in adolescents, and develops through a process leading from depression to suicidal ideation and self-injury. In this study, we analyzed and compared suicidal ideation among elementary school children from distinct families and school-related backgrounds. We conducted a cross-sectional study to investigate suicidal ideation in elementary school children in Miaoli County of Western Taiwan. Our study included 979 eligible participants and collected data, including suicidal ideation, depression scores, demographic characteristics, and family and school variables. The results revealed that 175 students (17.9%) exhibited depression, and 146 students (14.9%) had contemplated suicide. A quarrelsome family environment was found to be an important independent factor in child suicidal ideation after controlling for depression status. Children living in quarrelsome families showed a 3.7-fold risk of suicidal ideation compared with children in a harmonious family. Among boys living in quarrelsome family environments, suicidal ideation risk was 7.4-fold higher than for girls living in harmonious families. A 27-fold high increased suicidal ideation risk was also observed among the depressed children who living in the quarrelsome family environment, compared with the non-depressed in the harmonious family environment. This study provides novel evidence indicating the enhanced effects of a quarrelsome family environment combined with depression symptoms and among boys on suicidal ideation. These findings suggest of quarrels in a family environment playing an important role on elementary school children's psychological development, and may help parents in improving their mental health.

[Family environment risk factors of depression in adolescence].

PubMed

Greszta, Elzbieta

2006-01-01

General psychosocial theories of developmental psychopathology assert that family environment plays a significant role in forming both adaptive and maladaptive functioning of children. Also virtually all theories of depression assert that faulty parent-child relationships play a major role in the aetiology of this disorder. According these theoretical formulations familial risk factors have been the focus of most research on depression in adolescence. Several studies have shown that insecure attachment and parenting characterized by coldness, rejection, harsh discipline and unsupportive behaviour is positively related to adolescent depressive symptoms. Some research indicates that authoritative parenting, conceptualized as a composite of warmth, accept-involvement, firm control, and democratic discipline, is associated with the least depressive symptoms among adolescents. Pathogenetic factors within the family environment, such as parental depression, changes of family structure, violence or neglect, can also contribute to depression in adolescence. A causal relationship between anomalous parenting and depression is probably the interplay among genetic, cognitive, emotional, interpersonal and family environmental factors.

A complete assembled genome sequence of wheat is not yet available. Therefore, model plant systems for wheat are very valuable. Brachypodium distachyon (Brachypodium) is such a system. The WRKY family of transcription factors is one of the most important families of plant transcriptional regulators with members regulating important agronomic traits. Studies of WRKY transcription factors in Brachypodium and wheat therefore promise to lead to new strategies for wheat improvement. We have identified and manually curated the WRKY transcription factor family from Brachypodium using a pipeline designed to identify all potential WRKY genes. 86 WRKY transcription factors were found, a total higher than all other current databases. We therefore propose that our numbering system (BdWRKY1-BdWRKY86) becomes the standard nomenclature. In the JGI v1.0 assembly of Brachypodium with the MIPS/JGI v1.0 annotation, nine of the transcription factors have no gene model and eleven gene models are probably incorrectly predicted. In total, twenty WRKY transcription factors (23.3%) do not appear to have accurate gene models. To facilitate use of our data, we have produced The Database of Brachypodium distachyon WRKY Transcription Factors. Each WRKY transcription factor has a gene page that includes predicted protein domains from MEME analyses. These conserved protein domains reflect possible input and output domains in signaling. The database also contains a BLAST search function where a large dataset of WRKY transcription factors, published genes, and an extensive set of wheat ESTs can be searched. We also produced a phylogram containing the WRKY transcription factor families from Brachypodium, rice, Arabidopsis, soybean, and Physcomitrella patens, together with published WRKY transcription factors from wheat. This phylogenetic tree provides evidence for orthologues, co-orthologues, and paralogues of Brachypodium WRKY transcription factors. The description of the WRKY transcription factor

This study was done to compare factors influencing children's self-esteem between two parent families and single parent families. The participants were 692 children aged 11 to 13 yr (388 in two parent families and 304 in single parent families) recruited from 20 community agencies and 5 elementary schools in Gyeonggi Province and Seoul City, South Korea. Data were collected from May to July, 2007 using a survey questionnaire containing items on self-esteem, internal control, problematic behavior, school record, family hardiness, parent-child communication and social support. The data were analyzed using SPSS 15.0 program and factors affecting children's self-esteem were analyzed by stepwise multiple regression. Scores for the study variables were significantly different between the two groups. The factors influencing children's self-esteem were also different according to family type. For two parent families, internal control, problematic behavior, school record, and parent-child communication significantly predicted the level of self-esteem (adjusted R(2)=.505, p<.001). For single parent families, social support, family hardiness, internal control, problematic behavior, school record, and parent-child communication significantly predicted the level of self-esteem (adjusted R(2)=.444, p<.001). Nurse working with children should consider family type-specific factors influencing their self-esteem.

Children's loneliness, sense of coherence, family climate, and hope: developmental risk and protective factors.

The study examined the contributions of individual and familial variables for the prediction of loneliness as a developmental risk and the sense of coherence as a protective factor. The sample consisted of 287 children from grades 5-6. Their loneliness, sense of coherence, hope, effort, and family climate were assessed. Separate hierarchical multiple regression analyses revealed that family cohesion and children's hope contributed to the explanation of the risk and protective outcomes. Yet, the contribution of the family adaptability was not significant. Cluster analysis of the family climate dimensions (i.e., cohesion and adaptability) was performed to clarify the interactive roles of family adaptability together with family cohesion. The authors identified 4 separate family profiles: Children in the 2 cohesive families' clusters (Cohesive Structured Families and Cohesive Adaptable Families) reported the lowest levels of loneliness and the highest levels of personal strengths. Children within rigid and noncohesive family cluster reported the highest levels of loneliness and the lowest levels of children's sense of coherence. The unique role of the family flexibility within nonsupportive family systems was demonstrated. The results further clarified the unique profiles' characteristics of the different family clusters and their adjustment indexes in terms of loneliness and personal strengths.

Secretome Screening Reveals Fibroblast Growth Factors as Novel Inhibitors of Viral Replication.

2018-06-13

Cellular antiviral programs can efficiently inhibit viral infection. These programs are often initiated through signaling cascades induced by secreted proteins such as type I interferons, IL-6 or TNF-α. Here, we generated an arrayed library of 756 human secreted proteins to perform a secretome screen focused on the discovery of novel modulators of viral entry and/or replication. The individual secreted proteins were tested for their capacity to inhibit infection by two replication-competent recombinant vesicular stomatitis viruses (VSV) with distinct glycoproteins utilizing different entry pathways. Fibroblast growth factor 16 (FGF16) was identified and confirmed as the most prominent novel inhibitor of both VSVs and therefore of viral replication and not entry. Importantly, an antiviral interferon signature was completely absent in FGF16 treated cells. Nevertheless, the antiviral effect of FGF16 is broad as it was evident on multiple cell types and also on infection of Coxsackievirus. In addition, other members of the FGF family also inhibited viral infection. Thus, our unbiased secretome screen revealed a novel protein family capable of inducing a cellular antiviral state. This previously unappreciated role of the FGF family may have implications for the development of new antivirals and the efficacy of oncolytic virus therapy. Importance Viruses infect human cells in order to replicate, while human cells aim to resist infection. Several cellular antiviral programs have therefore evolved to resist infection. Knowledge of these programs is essential for the design of antiviral therapeutics in the future. The induction of antiviral programs is often initiated by secreted proteins such as interferons. We hypothesized that other secreted proteins may also promote resistance to viral infection. Thus we tested 756 human secreted proteins for their capacity to inhibit two pseudotypes of vesicular stomatitis virus (VSV). In this first secretome screen on viral infection

Personality Factors in the Long Life Family Study

Objectives. To evaluate personality profiles of Long Life Family Study participants relative to population norms and offspring of centenarians from the New England Centenarian Study. Method. Personality domains of agreeableness, conscientiousness, extraversion, neuroticism, and openness were assessed with the NEO Five-Factor Inventory in 4,937 participants from the Long Life Family Study (mean age 70 years). A linear mixed model of age and gender was implemented adjusting for other covariates. Results. A significant age trend was found in all five personality domains. On average, the offspring generation of long-lived families scored low in neuroticism, high in extraversion, and within average values for the other three domains. Older participants tended to score higher in neuroticism and lower in the other domains compared with younger participants, but the estimated scores generally remained within average population values. No significant differences were found between long-lived family members and their spouses. Discussion. Personality factors and more specifically low neuroticism and high extraversion may be important for achieving extreme old age. In addition, personality scores of family members were not significantly different from those of their spouses, suggesting that environmental factors may play a significant role in addition to genetic factors.

Integration and diversity of the regulatory network composed of Maf and CNC families of transcription factors.

Recent progress in the analysis of transcriptional regulation has revealed the presence of an exquisite functional network comprising the Maf and Cap 'n' collar (CNC) families of regulatory proteins, many of which have been isolated. Among Maf factors, large Maf proteins are important in the regulation of embryonic development and cell differentiation, whereas small Maf proteins serve as obligatory heterodimeric partner molecules for members of the CNC family. Both Maf homodimers and CNC-small Maf heterodimers bind to the Maf recognition element (MARE). Since the MARE contains a consensus TRE sequence recognized by AP-1, Jun and Fos family members may act to compete or interfere with the function of CNC-small Maf heterodimers. Overall then, the quantitative balance of transcription factors interacting with the MARE determines its transcriptional activity. Many putative MARE-dependent target genes such as those induced by antioxidants and oxidative stress are under concerted regulation by the CNC family member Nrf2, as clearly proven by mouse germline mutagenesis. Since these genes represent a vital aspect of the cellular defense mechanism against oxidative stress, Nrf2-null mutant mice are highly sensitive to xenobiotic and oxidative insults. Deciphering the molecular basis of the regulatory network composed of Maf and CNC families of transcription factors will undoubtedly lead to a new paradigm for the cooperative function of transcription factors.

Despite of the increase in the prevalence of hypertension in Portugal, the importance of genetic factors in blood pressure (BP) has not been studied extensively in our country. To verify the indirect presence of vertical transmission of genetic factors between parents and children in BP values, and to estimate the magnitude of genetic factors contributing for variation in BP values in the population. Sample size comprises 367 individuals (164 parents and 203 children) pertaining the 107 nuclear families participating in 'Familias Activas' project, proceeding from different regions of North Portugal. The BP was measured with Omron model M6 (HEM-7001-E) digital device. SPSS 15.0 was used for data analysis; PEDSTATS was used to verify the structure of each family data. Familial correlations and heritability estimates were computed in FCOR and ASSOC modules of S.A.G.E. version 5.3. For systolic BP (SBP), correlation values were low to moderate (0.21< or = r < or =0.35); for diastolic BP (DBP) values were found to be moderate (0.24< or = r < or =0. 50). Genetic factors explain 43 and 49% of the total variation in SBP and DBP, respectively. A moderate amount of the SBP and the DBP is accounted for by genetic factors.

MCAT elements and the TEF-1 family of transcription factors in muscle development and disease.

Yoshida, Tadashi

2008-01-01

MCAT elements are located in the promoter-enhancer regions of cardiac, smooth, and skeletal muscle-specific genes including cardiac troponin T, beta-myosin heavy chain, smooth muscle alpha-actin, and skeletal alpha-actin, and play a key role in the regulation of these genes during muscle development and disease. The binding factors of MCAT elements are members of the transcriptional enhancer factor-1 (TEF-1) family. However, it has not been fully understood how these transcription factors confer cell-specific expression in muscle, because their expression patterns are relatively broad. Results of recent studies revealed multiple mechanisms whereby TEF-1 family members control MCAT element-dependent muscle-specific gene expression, including posttranslational modifications of TEF-1 family members, the presence of muscle-selective TEF-1 cofactors, and cell-selective control of TEF-1 accessibility to MCAT elements. In addition, of particular interest, recent studies regarding MCAT element-dependent transcription of the myocardin gene and the smooth muscle alpha-actin gene in muscle provide evidence for the transcriptional diversity among distinct cell types and subtypes. This article summarizes the role of MCAT elements and the TEF-1 family of transcription factors in muscle development and disease, and reviews recent progress in our understanding of the transcriptional regulatory mechanisms involved in MCAT element-dependent muscle-specific gene expression.

The aim of this study was to assess maternal psychiatric symptoms, family functioning and parenting styles in children with encopresis. Forty-one children with encopresis were compared to 29 children without any psychiatric disorder. Higher maternal psychiatric symptoms were found in children with encopresis. The general family functioning and strictness/supervision in parenting were significant predictors of encopresis. Family functioning may be screened in children with encopresis, especially when standard interventions have had limited success. Identification and treatment of familial factors may enhance the treatment efficacy in encopresis. © 2014 Japan Pediatric Society.

HES/HEY genes encode a family of basic helix-loop-helix (bHLH) transcription factors with both bHLH and Orange domain. HES/HEY proteins are direct targets of the Notch signaling pathway and play an essential role in developmental decisions, such as the developments of nervous system, somitogenesis, blood vessel and heart. Despite their important functions, the origin and evolution of this HES/HEY gene family has yet to be elucidated. In this study, we identified genes of the HES/HEY family in representative species and performed evolutionary analysis to elucidate their origin and evolutionary process. Our results showed that the HES/HEY genes only existed in metazoans and may originate from the common ancestor of metazoans. We identified HES/HEY genes in more than 10 species representing the main lineages. Combining the bHLH and Orange domain sequences, we constructed the phylogenetic trees by different methods (Bayesian, ML, NJ and ME) and classified the HES/HEY gene family into four groups. Our results indicated that this gene family had undergone three expansions, which were along with the origins of Eumetazoa, vertebrate, and teleost. Gene structure analysis revealed that the HES/HEY genes were involved in exon and/or intron loss in different species lineages. Genes of this family were duplicated in bony fishes and doubled than other vertebrates. Furthermore, we studied the teleost-specific duplications in zebrafish and investigated the expression pattern of duplicated genes in different tissues by RT-PCR. Finally, we proposed a model to show the evolution of this gene family with processes of expansion, exon/intron loss, and motif loss. Our study revealed the evolution of HES/HEY gene family, the expression and function divergence of duplicated genes, which also provide clues for the research of Notch function in development. This study shows a model of gene family analysis with gene structure evolution and duplication.

A reduction in academic achievement over the course of adolescence has been observed. School failure is characterized by difficulties to teaching school goals. A variety of other behavioral problems are often associated with school failure. Child-to-parent violence has been associated with different school problems. The main objective of current study was to examine the contribution of family variables (parental education level, family cohesion, and positive family discipline) on academic failure and child-to-parent violence of adolescents from a community sample. Moreover, a goal was to explore if academic failure was a valid predictor of child-to-parent violence. To this end, it has been developed a comprehensive statistical model through Structural Equation Modeling (SEM). Participants were 584 children from eight secondary schools in the Basque Country (Spain) and aged between 12 and 18. Among other scales Conflict Tactics Scale and Family Environment Scale were administrated for measuring child-to-parent violence and family cohesion environment, respectively. The structural model revealed that parental education level is a relevant protective factor against academic failure. Positive family discipline (inductive discipline, supervision, and penalty) show a significant association with child-to-parent violence and academic failure. Disciplinary practices could be more efficient to prevent child-to-parent violence or school failure if children perceive a positive environment in their home. However, these findings could be explained by inverse causality, because some parents respond to child-to-parent violence or academic failure with disciplinary strategies. School failure had indirect effects on child-to-parent violence through family cohesion. For all that, education policies should focus on parental education courses for disadvantaged families in order to generate appropriate learning environments at home and to foster improvement of parent

1999-06-01

Examined the relations among family protective factors, stressful events, and behavioral adjustment of 64 African American 6th graders. The youths reported on family stressors, father-figure involvement, and kin support. Their primary caregivers reported on parenting, father-figure involvement, and family stressors. Teachers reported on child social skill deficits, acting out, and shy or anxious behavior. Based on regression analyses, stress exposure associated positively with child social skill deficits, acting out, and shy or anxious behavior. Parental warmth was associated negatively with shy or anxious behavior. Parental use of corporal punishment was associated positively with child acting out. For youth exposed to high numbers of family stressors, parental demandingness was associated negatively with child acting out and kin support was associated negatively with acting out and shy or anxious behavior, suggesting that these family factors partially shield children from the negative effects of stress.

Patterns of Positive Selection of the Myogenic Regulatory Factor Gene Family in Vertebrates

2014-01-01

The functional divergence of transcriptional factors is critical in the evolution of transcriptional regulation. However, the mechanism of functional divergence among these factors remains unclear. Here, we performed an evolutionary analysis for positive selection in members of the myogenic regulatory factor (MRF) gene family of vertebrates. We selected 153 complete vertebrate MRF nucleotide sequences from our analyses, which revealed substantial evidence of positive selection. Here, we show that sites under positive selection were more frequently detected and identified from the genes encoding the myogenic differentiation factors (MyoG and Myf6) than the genes encoding myogenic determination factors (Myf5 and MyoD). Additionally, the functional divergence within the myogenic determination factors or differentiation factors was also under positive selection pressure. The positive selection sites were more frequently detected from MyoG and MyoD than Myf6 and Myf5, respectively. Amino acid residues under positive selection were identified mainly in their transcription activation domains and on the surface of protein three-dimensional structures. These data suggest that the functional gain and divergence of myogenic regulatory factors were driven by distinct positive selection of their transcription activation domains, whereas the function of the DNA binding domains was conserved in evolution. Our study evaluated the mechanism of functional divergence of the transcriptional regulation factors within a family, whereby the functions of their transcription activation domains diverged under positive selection during evolution.

This is a descriptive study with a qualitative approach, carried out during the second half of 2011, in a Pediatric Unit in a city in the extreme South of Brazil. The study aimed to understand the situations in which families reveal themselves as beings of rights during the hospitalization of the child. Fifteen family caregivers participated, divided into three sample groups. Data collection was conducted through semi-structured interviews, and the data were analyzed using open, axial and selective analysis. The study had the Grounded Theory as methodological framework. It was found that the family revealed itself as a being of rights, when recognized as such, is called and fights for their rights; suggests improvements for the care and maintains its autonomy, even if it has to submit to the decisions of the team in the child favor. It was concluded that is essential to allow them to be families in the hospital, enabling the exercise of their rights and citizenship.

2017-02-01

To evaluate whether family factors were associated with intellectual functioning among children with medically refractory epilepsy, and whether family factors moderate the relationship between patient/epilepsy-related variables and intellectual functioning. Children aged 4 to 18 years with medically refractory epilepsy who were evaluated for surgical candidacy were recruited. The authors assessed the association of intellectual quotient (IQ) with patient, epilepsy, and family factors. Family factors included parental education, household income, and validated parent-report measures of family functioning, family mastery and social support, and family demands. Univariable analyses showed that higher IQ scores were associated with an older age of epilepsy onset (β = .260, p = .009), fewer antiepileptic drugs (β = .248, p = .013), a shorter duration (β = .384, p < .001) and percentage of life with epilepsy (β = .419, p < .001), unilobar epileptogenic foci relative to multilobar foci (β = .274, p = .006), and lower family demands (β = .211, p = .035). In multivariable analysis, unilobar epileptogenic foci (p = .010) and a shorter percentage of life with epilepsy (p = .001) remained significant predictors of IQ. Exploratory moderation analyses found the relationship between the extent of epileptogenic foci and IQ to be moderated by family demands (p = .004); specifically, patients with unilobar epileptogenic onset had similar IQ scores irrespective of family demands, whereas patients with multilobar foci had lower IQ scores with increasing family demands. Family factors did not have a large impact on IQ among children with medically refractory epilepsy, although the moderating effect of family demands deserves further study. Epilepsy-related factors in this patient group may weaken the link between child IQ and family factors. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Family environment and its relation to adolescent personality factors.

Investigated the relationship between family social climate characteristics and adolescent personality functioning. The High School Personality Questionnaire (HSPQ) was administered to 80 high school students. These students and their parents also completed the Family Environment Scale (FES). Results of a stepwise multiple regression analysis indicated that one or more HSPQ scales had significant associations with each FES scale. Significant variance in child behavior was attributed to family social system functioning; however, no single family variable accounted for a major portion of the variance to the exclusion of other factors. It was concluded that child behavior varies with total system functioning, more than with separate system factors.

Is the Association Between Education and Fertility Postponement Causal? The Role of Family Background Factors.

A large body of literature has demonstrated a positive relationship between education and age at first birth. However, this relationship may be partly spurious because of family background factors that cannot be controlled for in most research designs. We investigate the extent to which education is causally related to later age at first birth in a large sample of female twins from the United Kingdom (N = 2,752). We present novel estimates using within-identical twin and biometric models. Our findings show that one year of additional schooling is associated with about one-half year later age at first birth in ordinary least squares (OLS) models. This estimate reduced to only a 1.5-month later age at first birth for the within-identical twin model controlling for all shared family background factors (genetic and family environmental). Biometric analyses reveal that it is mainly influences of the family environment-not genetic factors-that cause spurious associations between education and age at first birth. Last, using data from the Office for National Statistics, we demonstrate that only 1.9 months of the 2.74 years of fertility postponement for birth cohorts 1944-1967 could be attributed to educational expansion based on these estimates. We conclude that the rise in educational attainment alone cannot explain differences in fertility timing between cohorts.

Confronting developmental tasks and challenges associated with bridging two different cultures, Asian American adolescent girls face increasing risks for substance use. Identifying risk and protective factors in this population is essential, particularly when those factors can inform preventive programs. Guided by family interaction theory, the present cross-sectional study explored the associations of psychological and familial factors with use of alcohol, prescription drugs, and other drugs among early-adolescent Asian American girls. Between August 2007 and March 2008, 135 pairs of Asian American girls (mean age 13.21 years, SD = 0.90) and their mothers (mean age 39.86 years, SD = 6.99) were recruited from 19 states that had significant Asian populations. Girls and mothers each completed an online survey. Relative to girls who did not use substances, girls who did had higher levels of depressive symptoms, perceived peer substance use, and maternal substance use. Multiple logistic regression modeling revealed that they also had significantly lower levels of body satisfaction, problem-solving ability, parental monitoring, mother-daughter communication, family involvement, and family rules about substance use. Household composition, acculturation, and academic achievement were not associated with girls’ substance use. These findings point to directions for substance abuse prevention programming among Asian American girls. PMID:22082244

To examine family risk factors associated with dissociative symptoms among homeless and runaway youth. Three hundred and twenty-eight homeless and runaway youth were interviewed using a systematic sampling strategy in metropolitan Seattle. Homeless young people were interviewed on the streets and in shelters by outreach workers in youth service agencies. The current study revealed widespread prevalence of dissociative symptoms among these young people. Multivariate analyses revealed that sexual abuse, physical abuse, and family mental health problems were all positively associated with dissociative symptoms. No gender differences were found for any of the models. Dissociative behavior is widespread among these youth and may pose a serious mental health concern. Some young people experience numerous stressors, and with few resources and little support available, many may invoke maladaptive strategies such as dissociative behavior to handle such situations, which may in turn be detrimental to their mental health. Unless youth are provided with programs and intervention, the cycle of abuse that they have experienced at home is likely to continue on the street.

In Canada, friends and family members are becoming increasingly responsible for providing palliative care in the home. This is resulting in some caregivers experiencing high levels of stress and burden that may ultimately surpass their ability to cope. Recent palliative care research has demonstrated the potential for caregiver resilience within such contexts. This research, however, is primarily focused on exploring individual-level factors that contribute to resilience, minimizing the inherent complexity of this concept, and how it is simultaneously influenced by one's social context. Therefore, our study aims to identify socio-environmental factors that contribute to palliative family caregiver resilience in the Canadian homecare context. Drawing on ethnographic fieldnotes and semistructured interviews with family caregivers, care recipients, and homecare nurses, this secondary analysis employs an intersectionality lens and qualitative case study approach to identify socio-environmental factors that facilitate family caregivers' capacity for resilience. Following a case study methodology, two cases are purposely selected for analysis. Findings demonstrate that family caregiver resilience is influenced not only by individual-level factors but also by the social environment, which sets the lived context from which caregiving roles are experienced. Thematic findings of the two case studies revealed six socio-environmental factors that play a role in shaping resilience: access to social networks, education/knowledge/awareness, employment status, housing status, geographic location, and life-course stage. Findings contribute to existing research on caregiver resilience by empirically demonstrating the role of socio-environmental factors in caregiving experiences. Furthermore, utilizing an intersectional approach, these findings build on existing notions that resilience is a multidimensional and complex process influenced by numerous related variables that intersect

This cross-sectional study was done to compare factors influencing young adolescents' aggression according to family structure. Participants were 680 young adolescents aged 11 to 15 years (113 in single father families, 136 in single mother families, 49 in grandparent families, and 382 in both-parent families). All measures were self-administered. Data were analyzed using SPSS 18.0 program and factors affecting young adolescents' aggression were analyzed by stepwise multiple regression. Levels of young adolescents' aggression and all variables were significantly different among the four family structure groups. Factors influencing young adolescents' aggression were also different according to these 4 groups. For single father families, depression-anxiety and family hardiness significantly predicted the level of young adolescents' aggression (adjusted R square=.37, p<.001). For single mother families, depression-anxiety, gender, and friends' support significantly predicted the level of young adolescents' aggression (adjusted R square=.58, p<.001). For grandparent families, depression-anxiety and family support significantly predicted the level of young adolescents' aggression (adjusted R square=.58, p<.001). For both-parent families, depression-anxiety, family hardiness, and friends' support significantly predicted the level of young adolescents' aggression (adjusted R square=.48, p<.001). Nurses working with young adolescents should consider family structure-specific factors influencing aggression in this population.

Comparative and Evolutionary Analysis of the HES/HEY Gene Family Reveal Exon/Intron Loss and Teleost Specific Duplication Events

Background HES/HEY genes encode a family of basic helix-loop-helix (bHLH) transcription factors with both bHLH and Orange domain. HES/HEY proteins are direct targets of the Notch signaling pathway and play an essential role in developmental decisions, such as the developments of nervous system, somitogenesis, blood vessel and heart. Despite their important functions, the origin and evolution of this HES/HEY gene family has yet to be elucidated. Methods and Findings In this study, we identified genes of the HES/HEY family in representative species and performed evolutionary analysis to elucidate their origin and evolutionary process. Our results showed that the HES/HEY genes only existed in metazoans and may originate from the common ancestor of metazoans. We identified HES/HEY genes in more than 10 species representing the main lineages. Combining the bHLH and Orange domain sequences, we constructed the phylogenetic trees by different methods (Bayesian, ML, NJ and ME) and classified the HES/HEY gene family into four groups. Our results indicated that this gene family had undergone three expansions, which were along with the origins of Eumetazoa, vertebrate, and teleost. Gene structure analysis revealed that the HES/HEY genes were involved in exon and/or intron loss in different species lineages. Genes of this family were duplicated in bony fishes and doubled than other vertebrates. Furthermore, we studied the teleost-specific duplications in zebrafish and investigated the expression pattern of duplicated genes in different tissues by RT-PCR. Finally, we proposed a model to show the evolution of this gene family with processes of expansion, exon/intron loss, and motif loss. Conclusions Our study revealed the evolution of HES/HEY gene family, the expression and function divergence of duplicated genes, which also provide clues for the research of Notch function in development. This study shows a model of gene family analysis with gene structure evolution and

Structure-preserving and rank-revealing QR-factorizations

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bischof, C.H.; Hansen, P.C.

1991-11-01

The rank-revealing QR-factorization (RRQR-factorization) is a special QR-factorization that is guaranteed to reveal the numerical rank of the matrix under consideration. This makes the RRQR-factorization a useful tool in the numerical treatment of many rank-deficient problems in numerical linear algebra. In this paper, a framework is presented for the efficient implementation of RRQR algorithms, in particular, for sparse matrices. A sparse RRQR-algorithm should seek to preserve the structure and sparsity of the matrix as much as possible while retaining the ability to capture safely the numerical rank. To this end, the paper proposes to compute an initial QR-factorization using amore » restricted pivoting strategy guarded by incremental condition estimation (ICE), and then applies the algorithm suggested by Chan and Foster to this QR-factorization. The column exchange strategy used in the initial QR factorization will exploit the fact that certain column exchanges do not change the sparsity structure, and compute a sparse QR-factorization that is a good approximation of the sought-after RRQR-factorization. Due to quantities produced by ICE, the Chan/Foster RRQR algorithm can be implemented very cheaply, thus verifying that the sought-after RRQR-factorization has indeed been computed. Experimental results on a model problem show that the initial QR-factorization is indeed very likely to produce RRQR-factorization.« less

The importance of a family-centered approach in family practice has been emphasized. Knowledge about factors associated with higher family-centered involvement seems beneficial to stimulate its realization. German office-based family physicians completed a questionnaire addressing several aspects of family-centered care. Logistic regression was used to identify associations with the involvement overall and in different domains: routine inquiry and documentation of family-related information, family orientation regarding diagnosis and treatment, family-oriented dialogues, family conferences, and case-related collaboration with marriage and family therapists. We found significant associations between physicians' family-centered involvement and expected patient receptiveness, perceived impact of the family's influence on health, self-perceived psychosocial family-care competences (overall and concerning concepts for family orientation, psychosocial intervention in family conferences, and the communication of the idea of family counseling), advanced training in psychosocial primary care (PPC), personal acquaintance with family therapists (regarding case-related collaboration), and rural office environment. Increased emphasis on the family's influence on health in medical education and training, the provision of concepts for a family-centered perspective, and versatile skills for psychosocial intervention and inquiry of patient preferences, as well as the strengthening of networking between family physicians and family therapists, might promote the family-centered approach in family practice.

An important aspect of research into the link between genes and behaviour concerns the identification of familial determination. There is evidence for familial factors in selective deficits, such as developmental dyslexia and developmental prosopagnosia. Colour agnosia concerns a selective neuropsychological condition in which colour perception is intact, while the identification and naming of colour is disrupted. We recently demonstrated that this deficit can occur as a developmental deficit. Here, we show that there is a familial factor in the development of colour agnosia by reporting the colour processing abilities of the mother and the daughters of a man with developmental colour agnosia.

Background Improving use of family planning services is key to improving maternal health in Africa, and provision of quality of care in family planning services is critical to support higher levels of contraceptive uptake. The objective of this systematic review was to synthesize the available evidence on factors determining the quality of care in family planning services in Africa. Methods Quantitative and qualitative studies undertaken in Africa, published in English, in grey and commercial literature, between 1990 and 2015 were considered. Methodological quality of included studies was assessed using standardized tools. Findings from the quantitative studies were summarized using narrative and tables. Client satisfaction was used to assess the quality of care in family planning services in the quantitative component of the review. Meta-aggregation was used to synthesize the qualitative study findings. Results From 4334 records, 11 studies (eight quantitative, three qualitative) met the review eligibility criteria. The review found that quality of care was influenced by client, provider and facility factors, and structural and process aspects of the facilities. Client’s waiting time, provider competency, provision/prescription of injectable methods, maintaining privacy and confidentiality were the most commonly identified process factors. The quality of stock inventory was the most commonly identified structural factor. The quality of care was also positively associated with privately-owned facilities. The qualitative synthesis revealed additional factors including access related factors such as ‘pre-requisites to be fulfilled by the clients and cost of services, provider workload, and providers’ behaviour. Conclusion There is limited evidence on factors determining quality of care in family planning services in Africa that shows quality of care is influenced by multiple factors. The evidence suggests that lowering access barriers and avoiding unnecessary

Family support and other social factors precipitating suicidal ideation.

PubMed

Hirsch, J; Ellis, J B

1995-01-01

To examine the effects of family support and demographics on suicidal behavior, 385 subjects completed a demographic questionnaire and a Suicidal Ideation Questionnaire (SIQ). Sixteen percent described themselves as "serious" ideators, while 59% were seen as ideators, numbers consistent with past suicide research. Multiple regression analyses revealed that the type of caregiver a person reported having while growing up accounted for a significant amount of the variance on ideator status. Serious ideators were more common among single parent households. Although many demographic variables were assessed, only the primary caregiver a person had as a child impacted their status as a suicidal ideator. This suggests that suicidal behaviors may occur due to a complex interaction between social factors and childhood care. The influence of living in a single-parent home may contribute to whether or not a person considers suicide.

To combat infection to biotic stress plants elicit the biosynthesis of numerous natural products, many of which are valuable pharmaceutical compounds. Jasmonate is a central regulator of defense response to pathogens and accumulation of specialized metabolites. Catharanthus roseus produces a large number of terpenoid indole alkaloids (TIAs) and is an excellent model for understanding the regulation of this class of valuable compounds. Recent work illustrates a possible role for the Catharanthus WRKY transcription factors (TFs) in regulating TIA biosynthesis. In Arabidopsis and other plants, the WRKY TF family is also shown to play important role in controlling tolerance to biotic and abiotic stresses, as well as secondary metabolism. Here, we describe the WRKY TF families in response to jasmonate in Arabidopsis and Catharanthus. Publically available Arabidopsis microarrays revealed at least 30% (22 of 72) of WRKY TFs respond to jasmonate treatments. Microarray analysis identified at least six jasmonate responsive Arabidopsis WRKY genes (AtWRKY7, AtWRKY20, AtWRKY26, AtWRKY45, AtWRKY48, and AtWRKY72) that have not been previously reported. The Catharanthus WRKY TF family is comprised of at least 48 members. Phylogenetic clustering reveals 11 group I, 32 group II, and 5 group III WRKY TFs. Furthermore, we found that at least 25% (12 of 48) were jasmonate responsive, and 75% (9 of 12) of the jasmonate responsive CrWRKYs are orthologs of AtWRKYs known to be regulated by jasmonate. Overall, the CrWRKY family, ascertained from transcriptome sequences, contains approximately 75% of the number of WRKYs found in other sequenced asterid species (pepper, tomato, potato, and bladderwort). Microarray and transcriptomic data indicate that expression of WRKY TFs in Arabidopsis and Catharanthus are under tight spatio-temporal and developmental control, and potentially have a significant role in jasmonate signaling.

2011-01-01

Background: Studies have shown that family history is a risk factor for COPD, but have not accounted for family history of smoking. Therefore, we sought to identify the effects of family history of smoking and family history of COPD on COPD susceptibility. Methods: We compared 821 patients with COPD to 776 control smokers from the Genetic Epidemiology of COPD (COPDGene) Study. Questionnaires captured parental histories of smoking and COPD, as well as childhood environmental tobacco smoke (ETS) exposure. Socioeconomic status was defined by educational achievement. Results: Parental history of smoking (85.5% case patients, 82.9% control subjects) was more common than parental history of COPD (43.0% case patients, 30.8% control subjects). In a logistic regression model, parental history of COPD (OR, 1.73; P < .0001) and educational level (OR, 0.48 for some college vs no college; P < .0001) were significant predictors of COPD, but parental history of smoking and childhood ETS exposure were not significant. The population-attributable risk from COPD family history was 18.6%. Patients with COPD with a parental history had more severe disease, with lower lung function, worse quality of life, and more frequent exacerbations. There were nonsignificant trends for more severe emphysema and airway disease on quantitative chest CT scans. Conclusions: Family history of COPD is a strong risk factor for COPD, independent of family history of smoking, personal lifetime smoking, or childhood ETS exposure. Although further studies are required to identify genetic variants that influence COPD susceptibility, clinicians should question all smokers, especially those with known or suspected COPD, regarding COPD family history.

The literature on family predictors of substance use for the general population is reviewed and compared to findings for three specific ethnic groups: black, white and Asian-Americans. Rates of substance use initiation are examined in a sample of 919 urban 5th-grade students. Ethnic differences on measures of family predictors are examined and significant ethnic differences are found on several of these factors. Finally, separate regressions for black, white and Asian American youths of family factors on the variety of substances initiated examine ethnic similarities and differences in predictors. The results demonstrate significant differences by ethnicity in family management practices, involvement in family activity, sibling deviance, parental disapproval of children's drinking and family structure. The regression equations identified unique as well as common predictors of the variety of substances initiated by the end of 5th grade. Implications of the results are discussed. PMID:1285743

This study examined sociocultural and familial factors related to the prevention of childhood obesity. Primary caregivers of 6- to 10-year-old children representing several ethnic populations in Saipan participated in 4 focus groups (N=32). Trained moderators used semi-structured interviews and qualitative methods were used in data analysis. A central theme with several related factors emerged. The theme was a conflict expressed by the primary caregiver between sociocultural values, family expectations, traditional dietary beliefs and attitudes, and knowledge about food and disease. These findings have important implications for designing culturally sensitive interventions for prevention of childhood obesity.

Members of the Dof transcription factor family in Triticum aestivum are associated with light-mediated gene regulation.

PubMed

Shaw, Lindsay M; McIntyre, C Lynne; Gresshoff, Peter M; Xue, Gang-Ping

2009-11-01

DNA binding with One Finger (Dof) protein is a plant-specific transcription factor implicated in the regulation of many important plant-specific processes, including photosynthesis and carbohydrate metabolism. This study has identified 31 Dof genes (TaDof) in bread wheat through extensive analysis of current nucleotide databases. Phylogenetic analysis suggests that the TaDof family can be divided into four clades. Expression analysis of the TaDof family across all major organs using quantitative RT-PCR and searches of the wheat genome array database revealed that the majority of TaDof members were predominately expressed in vegetative organs. A large number of TaDof members were down-regulated by drought and/or were responsive to the light and dark cycle. Further expression analysis revealed that light up-regulated TaDof members were highly correlated in expression with a number of genes that are involved in photosynthesis or sucrose transport. These data suggest that the TaDof family may have an important role in light-mediated gene regulation, including involvement in the photosynthetic process.

Several risk factors for schizophrenia have yet been identified. The aim of our study was to investigate how certain childhood and adolescent risk factors predict the age of onset of psychosis in patients with and without a familial component (i.e. a relative with schizophrenia or schizoaffective disorder). Aside from the age of onset of psychosis, we examined the risk factors for schizophrenia including obstetric complications, birth during winter or spring, behavioral deviances or delayed motor and speech development, exposure to adverse life events and exposure to substance use within a group of 100 patients (45 female, 55 male) with a mean age (± standard deviation) of 35.15 ± 13.21. Birth complications and cannabis abuse are predictors for an earlier onset of schizophrenia in patients with non-familial schizophrenia. No environmental risk factors for an earlier age of onset in familial schizophrenia have been identified. Certain environmental risk factors for schizophrenia seem to have an impact on the age of onset of psychosis in non-familial schizophrenia, they do not seem to have an impact on familial schizophrenia.

ABSTRACT Background The family as a unit of care has great effect in tackling adolescent problems and this could be influenced by family functioning. Objective This study assesses the relationship between adolescents’ family functioning with socio-demographic characteristics and behavioural risk factors. Method The research was a cross-sectional, hospital-based study carried out at the General Outpatients Department, University College Hospital (GOPD, UCH), Ibadan, over a period of three months. Four hundred subjects were recruited using a modified Guideline for Adolescent Preventive Services (GAPS) questionnaire, with an incorporated family APGAR (Adaptation, Partnership, Growth, Affection, Resolve) score table. The results were analysed using the Statistical Package for Social Sciences (SPSS), version 11 and the findings on the family assessment and behavioural risk factors were relayed to the respondents. Results The ages of the adolescents ranged from 10 to 19 years. Of the subjects, 8% were sexually active. Mean age for first coitus among the respondents was 15 ± 2.4 years. The rate of ingestion of alcohol and cigarette smoking was very low. The family APGAR scores obtained revealed that 84.5% subjects were rated as having a functional family (7–10 points) and 15.5% of the subjects were rated as having a dysfunctional family (0–6 points). There was a significant association between perceived family function and subjects’ occupation (p = 0.01), parent social class (p = 0.00) and subjects’ sexual activities (p = 0.00). Conclusion The majority of the adolescents were rated as having functional families. Dysfunctional families had significantly sexually active respondents.

Our objective was to examine the relationships of factors associated with children's emotional well-being 2 years after diagnosis, and to examine if these relationships are mediated or moderated by family factors. Data came from a multicenter prospective cohort study of children with newly diagnosed epilepsy from across Canada (Health-Related Quality of Life in Children with Epilepsy Study; HERQULES, n = 373). Emotional well-being was assessed using the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55). The relationships between clinical factors, family factors, and emotional well-being were assessed using multiple regression analyses. Family functioning, family stress, and repertoire of resources that the families had to adapt to stressful events were significantly associated with poor emotional well-being 2 years after diagnosis (p < 0.05) in the multivariable analysis. The effect of parental depressive symptoms was partially mediated by family functioning and family stress (p < 0.01 and p = 0.02, respectively). Family resources acted as a moderator in the relationship between severity of epilepsy and emotional well-being (p < 0.05). Based on our findings, efforts to strengthen the family environment may warrant attention. We suggest that clinicians take a family centered care approach by including families in treatment planning. Family centered care has been shown to improve family well-being and coping and in turn may reduce the impact of clinical factors on emotional well-being to improve long-term health-related quality of life.

To characterise the family activity environment in a questionnaire format, assess the questionnaire's reliability and describe its predictive ability by examining the relationships between the family activity environment and children's health behaviours - physical activity, screen time and fruit and vegetable intake. This paper describes the creation of a tool, based on previously validated scales, adapted from the food domain. Data are from 106 children and their parents (Adelaide, South Australia). Factor analysis was used to characterise factors within the family activity environment. Pearson-Product Moment correlations between the family environment and child outcomes, controlling for demographic variation, were examined. Three factors described the family activity environment - parental activity involvement, opportunity for role modelling and parental support for physical activity - and explained 37.6% of the variance. Controlling for demographic factors, the scale was significantly correlated with children's health behaviour - physical activity (r=0.27), screen time (r=-0.24) and fruit and vegetable intake (r=0.34). The family activity environment questionnaire shows high internal consistency and moderate predictive ability. This study has built on previous research by taking a more comprehensive approach to measuring the family activity environment. This research suggests the family activity environment should be considered in family-based health promotion interventions. © 2011 The Authors. ANZJPH © 2011 Public Health Association of Australia.

"Trojan" is a leukocyte-specific, cell surface protein originally identified in the chicken. Its molecular function has been hypothesized to be related to anti-apoptosis and the proliferation of immune cells. The Trojan gene has been localized onto the Z sex chromosome. The adjacent two genes also show significant homology to Trojan, suggesting the existence of a novel gene/protein family. Here, we characterize this Trojan family, identify homologues in other species and predict evolutionary constraints on these genes. The two Trojan-related proteins in chicken were predicted as a receptor-type tyrosine phosphatase and a transmembrane protein, bearing a cytoplasmic immuno-receptor tyrosine-based activation motif. We identified the Trojan gene family in ten other bird species and found related genes in three reptiles and a fish species. The phylogenetic analysis of the homologues revealed a gradual diversification among the family members. Evolutionary analyzes of the avian genes predicted that the extracellular regions of the proteins have been subjected to positive selection. Such selection was possibly a response to evolving interacting partners or to pathogen challenges. We also observed an almost complete lack of intracellular positively selected sites, suggesting a conserved signaling mechanism of the molecules. Therefore, the contrasting patterns of selection likely correlate with the interaction and signaling potential of the molecules.

We aimed to determine whether different aspects of family functioning are associated with emotional and behavioral problems in adolescents with epilepsy and, if not, to document any indirect associations mediated by other family factors. This was a cross-sectional, multicenter study. A total of 297 adolescents with epilepsy and their parents participated. Adolescent psychopathology was measured using the Youth Self-Report. Family factors were classified into proximal (parent-child interaction), distal (parent characteristics), and contextual factors (family characteristics) in accordance to their level of proximity to the adolescent's everyday life. Regression analyses were used to analyze the unique and combined predictive power of family factors in relation to psychopathology. In total, 44 (14.8%) and 51 (17.2%) adolescents with epilepsy scored above the borderline cutoff (T-score ≥ 60) of internalizing and externalizing problems, respectively. Proximal and distal factors were independently associated with both internalizing and externalizing problems. High levels of parental depressive mood and parental overcontrol were the strongest factors contributing to internalizing and externalizing problems, respectively. Contextual factors were indirectly associated with both internalizing and externalizing problems through more proximal factors. Both proximal and distal family factors affect psychopathology in Korean adolescents with epilepsy. Parental feelings of depression and parental overcontrol are the strongest factors contributing to internalizing and externalizing problems, respectively. Copyright © 2016 Elsevier Inc.

Factors associated with family violence by persons with psychiatric disorders.

PubMed

Labrum, Travis; Solomon, Phyllis L

2016-10-30

Family violence by persons with psychiatric disorders (PD) is a highly under-researched area. The primary objective of the present analysis was to identify perpetrator, victim, and interaction/relationship factors associated with this phenomenon. The secondary objective was to examine the extent to which the relationship between caregiving and family violence was mediated by limit-setting practices used towards relatives with PD. 573 adults across the U.S. with an adult relative with PD completed an online survey. Multivariate logistic regression was performed examining the association of factors with the occurrence of family violence. Mediation was assessed with Sobel testing. Family violence was significantly associated with the following factors: perpetrator-income, illegal drug use, psychiatric hospitalization, treatment attendance, and use of medications; victim-age, employment status, income, and mental health status; interaction/relationship-parental relationship, co-residence, use of limit-setting practices, representative payeeship, and unofficial money management. Mediation was statistically significant. Increasing access to mental health and/or substance abuse treatment may decrease the risk of family violence. Interventions may benefit from attempting to decrease/modify the use of limit-setting practices. Where family representative payeeship or unofficial money management exists, it is advisable for practitioners to assess and address financial coercion and promote greater collaboration in financial decision-making.

Background/Aims Sociocultural and familial factors associated with weight bias internalization (WBI) are currently unknown. The present study explored the relationship between interpersonal sources of weight stigma, family weight history, and WBI. Methods Participants with obesity (N = 178, 87.6% female, 71.3% black) completed questionnaires that assessed the frequency with which they experienced weight stigma from various interpersonal sources. Participants also reported the weight status of their family members and completed measures of WBI, depression, and demographics. Participant height and weight were measured to calculate body mass index (BMI). Results Linear regression results (controlling for demographics, BMI, and depression) showed that stigmatizing experiences from family and work predicted greater WBI. Experiencing weight stigma at work was associated with WBI above and beyond the effects of other sources of stigma. Participants who reported higher BMIs for their mothers had lower levels of WBI. Conclusion Experiencing weight stigma from family and at work may heighten WBI, while having a mother with a higher BMI may be a protective factor against WBI. Prospective research is needed to understand WBI's developmental course and identify mechanisms that increase or mitigate its risk. PMID:29656285

Assessment of family functioning in Caucasian and Hispanic Americans: reliability, validity, and factor structure of the Family Assessment Device.

The purpose of this study was to examine the factor structure, reliability, and validity of the Family Assessment Device (FAD) among a national sample of Caucasian and Hispanic American families receiving public sector mental health services. A confirmatory factor analysis conducted to test model fit yielded equivocal findings. With few exceptions, indices of model fit, reliability, and validity were poorer for Hispanic Americans compared with Caucasian Americans. Contrary to our expectation, an exploratory factor analysis did not result in a better fitting model of family functioning. Without stronger evidence supporting a reformulation of the FAD, we recommend against such a course of action. Findings highlight the need for additional research on the role of culture in measurement of family functioning.

The 'behaviour problems' are having major impact on child's bodily and social development. The family provides emotional support to an individual as well as plays a major role in the formation of one's personality. The quality and nature of the parental nurturance that the child receives will profoundly influence his future development. The knowledge of these family factors associated with behaviour problems may be helpful to identify at risk children. To study the family factors associated with behaviour problems amongst children of 6-18 Yrs age group. an adopted urban slum area of Govt. Medical College, Miraj Dist-Sangli. Cross sectional study. the sample size was calculated based upon 40% prevalence obtained in pilot study. Total 600 Children in the age group of 6-18 years residing in the urban slum area and their parents were interviewed with the help of predesigned, pretested proforma. chi-square test and risk estimate with Odd's ratio. Our study result reveals significant association between prevalence of behaviour problems with absence of either or both real parents and alcoholism in the parent or care taker. The behaviour problems have good prognosis if they are recognized earlier. Family has great role in prevention of behaviour problems in children, so parental counseling may be helpful.

Family obligation values as a protective and vulnerability factor among low-income adolescent girls.

PubMed

Milan, Stephanie; Wortel, Sanne

2015-06-01

Adolescents' beliefs about family obligation often reflect cultural variations in their family context, and thus are important for understanding development among diverse youth. In this study, we test hypotheses about the role of family obligation values in risk behavior and mental health in a sample of 194 low-income adolescent girls (mean age = 15.2; 58% Latina, 28% African-American/Black). We hypothesized that family obligation values can be both a protective and vulnerability factor, depending on the type of outcome and the presence of other risk factors. Across the sample, higher family obligation values tended to occur with indicators of positive family functioning (e.g., more frequent communication, less maternal hostility) based on mother and adolescent reports. As hypothesized, family obligation values moderated the relationship between established risk factors and adjustment in distinct ways, such that high family obligation values decreased risk in some domains (i.e., a protective factor) but increased risk in other domains (i.e., a vulnerability factor). Specifically, high family obligation values diminished the relationship between peer norms for risky behavior (sex and substance use) and individual engagement in those behaviors. At the same time, high family obligation values magnified the relationship between exposure to negative life events and poor mental health (PTSD and depressive symptoms). The results suggest that family obligation is an important but complex aspect of development among diverse adolescent girls.

With the increased empirical and theoretical support for common factors in the psychotherapy literature, marriage and family therapy (MFT) scholars have begun discussing the inclusion of common factors in MFT training. However, there is very little empirical research on common factors training or how to include common factors in MFT curricula. The purpose of this phenomenological study was to investigate MFT students' experience with common factors training. Seventeen master's degree students who received training in common factors participated in the study. Data was comprised of participants' journal reflections and focus group interviews on their experience learning about common factors and how this influenced their work with clients. Participants' responses to the training were overwhelmingly positive and highlighted the ways in which studying common factors enhanced their confidence, understanding of MFT models, conceptual abilities, and clinical practice. Additional results and discussion about incorporating common factors in MFT training are presented. © 2018 American Association for Marriage and Family Therapy.

Identification and characterization of the WRKY transcription factor family in Pinus monticola.

2009-01-01

The WRKY gene family represents an ancient and highly complex group of transcription factors involved in signal transduction pathways of numerous plant developmental processes and host defense response. Up to now, most WRKY proteins have been identified in a few angiosperm species. Identification of WRKY genes in a conifer species would facilitate a comprehensive understanding of the evolutionary and function-adaptive process of this superfamily in plants. We performed PCR on genomic DNA to clone WRKY sequences from western white pine (Pinus monticola), one of the most valuable conifer species endangered by white pine blister rust (Cronartium ribicola). In total, 83 P. monticola WRKY (PmWRKY) sequences were identified using degenerate primers targeted to the WRKY domain. A phylogenetic analysis revealed that PmWRKY members fell into four major groups (1, 2a+2b, 2c, and 2d+2e) described in Arabidopsis and rice. Because of high genetic diversity of the PmWRKY family, a modified AFLP method was used to detect DNA polymorphism of this gene family. Polymorphic fragments accounted for 17%-35% of total PCR products in the AFLP profiles. Among them, one WRKY AFLP marker was linked to the major resistance gene (Cr2) against C. ribicola. The results of this study provide basic genomic information for a conifer WRKY gene family, which will pave the way for elucidating gene evolutionary mechanisms in plants and unveiling the precise roles of PmWRKY in conifer development and defense response.

This article aims to evaluate the effects of Brazil's recent economic growth on the monetary income, consumption patterns, and risk exposures of families with children enrolled in the public elementary school system in São Gonçalo, Rio de Janeiro State, Brazil. The article analyzes the following information on families of 447 children that participated in two waves in a longitudinal study: social stratum, per capita family income, evolution in income over a three-year period, and psychosocial factors. The findings showed a 74.8% increase in the families' income, accompanied by an increase in the consumption of material assets and access to health services. This increase should not be interpreted as a guarantee of improved living and health conditions, since it was spent on basic products and needs that do not substantially affect the families' form of social inclusion. Psychosocial risk factors were frequent among the families, but decreased during the study period, which may either reflect the improved family situation or result from the later stage in child development.

E26 transformation-specific (ETS) transcription factors are known to be involved in gene aberrations in various malignancies including prostate cancer; however, their role in melanoma oncogenesis has yet to be fully explored. We have completed a comprehensive fluorescence in situ hybridization (FISH)-based screen for all 27 members of the ETS transcription factor family on two melanoma tissue microarrays, representing 223 melanomas, 10 nevi, and 5 normal skin tissues. None of the melanoma cases demonstrated ETS fusions; however, 6 of 114 (5.3%) melanomas were amplified for ETV1 using a break-apart FISH probe. For the six positive cases, locus-controlled FISH probes revealed that two of six cases were amplified for the ETV1 region, whereas four cases showed copy gains of the entire chromosome 7. The remaining 26 ETS family members showed no chromosomal aberrations by FISH. Quantitative polymerase chain reaction showed an average 3.4-fold (P value = .00218) increased expression of ETV1 in melanomas, including the FISH ETV1-amplified cases, when compared to other malignancies (prostate, breast, and bladder carcinomas). These data suggest that a subset of melanomas overexpresses ETV1 and amplification of ETV1 may be one mechanism for achieving high gene expression. PMID:23908683

Higher caregiver burden is associated with poor quality of life among family caregivers. However, in Korea, very few studies have examined factors associated with caregiver burden. The present study investigated factors associated with caregiver burden among family caregivers of terminally ill Korean cancer patients, particularly modifiable factors as a potential target of intervention strategies. A cross-sectional study using self-administered questionnaires was performed. Sixty-four family caregivers of terminally ill cancer patients who were admitted to the hospice-palliative care unit of a university hospital in South Korea were included. To identify caregiver burden, the Caregiver Reaction Assessment scale (CRA) was used in this study. Time spent in providing care per day, number of visits per week from other family members, family functioning, and a positive subscale, self-esteem, of the CRA were deemed as modifiable factors. Other sociodemographic, caregiving characteristics of the subjects were non-modifiable factors. Longer time spent providing care per day, fewer weekly visits from other family members, poor family functioning, and low self-esteem were considered as modifiable factors associated with caregiver burden. Low monthly income and the spouse being the family caregiver were non-modifiable factors. Our study has practical significance in that it identifies modifiable factors that can be used to devise intervention strategies. Developing and applying such intervention strategies for alleviating the factors associated with high caregiver burden could be important for improving the quality of life of both patients and their families.

Esophageal squamous cell carcinoma is one of the deadliest of all the cancers. Its metastatic properties portend poor prognosis and high rate of recurrence. A more advanced method to identify new molecular biomarkers predicting disease prognosis can be whole exome sequencing. Here, we report the most effective genetic variants of the Notch signaling pathway in esophageal squamous cell carcinoma susceptibility by whole exome sequencing. We analyzed nine probands in unrelated familial esophageal squamous cell carcinoma pedigrees to identify candidate genes. Genomic DNA was extracted and whole exome sequencing performed to generate information about genetic variants in the coding regions. Bioinformatics software applications were utilized to exploit statistical algorithms to demonstrate protein structure and variants conservation. Polymorphic regions were excluded by false-positive investigations. Gene-gene interactions were analyzed for Notch signaling pathway candidates. We identified novel and damaging variants of the Notch signaling pathway through extensive pathway-oriented filtering and functional predictions, which led to the study of 27 candidate novel mutations in all nine patients. Detection of the trinucleotide repeat containing 6B gene mutation (a slice site alteration) in five of the nine probands, but not in any of the healthy samples, suggested that it may be a susceptibility factor for familial esophageal squamous cell carcinoma. Noticeably, 8 of 27 novel candidate gene mutations (e.g. epidermal growth factor, signal transducer and activator of transcription 3, MET) act in a cascade leading to cell survival and proliferation. Our results suggest that the trinucleotide repeat containing 6B mutation may be a candidate predisposing gene in esophageal squamous cell carcinoma. In addition, some of the Notch signaling pathway genetic mutations may act as key contributors to esophageal squamous cell carcinoma.

This study aims to explore and examine the conjectures surrounding the utilization of family planning services among currently married couples of childbearing age in Renk County. This study has adopted a qualitative method to collect data on factors affecting the utilization of family planning services through focus group discussions and in-depth interviews, in rural and urban areas of Renk County. It targeted married women, men as well as unmarried men and women. The researchers conducted nine focus group discussions and nine interviews at both Jelhak (rural setting) and Renk (urban setting). The results suggested that the people of Renk County prefer to have large families and therefore choose not to use family planning methods. The data collected was analyzed by means of thematic analysis. This included the construction of a thematic framework, coding, editing and categorization of available data as well as the creation of sub-themes. The result also suggested that perception is a main factor that affects utilization of family planning services with a majority of the people in Renk and Jelhak preferring to have many children in order to increase the family size for some reasons. These are linked to religion, social stigma and taboo that are attached to childless people or users of family planning methods for birth control purposes. The responses revealed some variation in perception between rural (Jelhak) and urban (Renk) areas. Respondents from Renk area reported that some people use family planning services for economic reasons that involve alleviation of financial difficulties and provision of better education when the family size is small. On the other hand, rural people from Jelhak perceive family planning to be socially un-acceptable. Furthermore, men and women of Jelhak reported that after each birth of a child, married couples avoid sexual relationship for a period of two years as means of family planning.

Trends in genome dynamics among major orders of insects revealed through variations in protein families.

Insects belong to a class that accounts for the majority of animals on earth. With over one million identified species, insects display a huge diversity and occupy extreme environments. At present, there are dozens of fully sequenced insect genomes that cover a range of habitats, social behavior and morphologies. In view of such diverse collection of genomes, revealing evolutionary trends and charting functional relationships of proteins remain challenging. We analyzed the relatedness of 17 complete proteomes representative of proteomes from insects including louse, bee, beetle, ants, flies and mosquitoes, as well as an out-group from the crustaceans. The analyzed proteomes mostly represented the orders of Hymenoptera and Diptera. The 287,405 protein sequences from the 18 proteomes were automatically clustered into 20,933 families, including 799 singletons. A comprehensive analysis based on statistical considerations identified the families that were significantly expanded or reduced in any of the studied organisms. Among all the tested species, ants are characterized by an exceptionally high rate of family gain and loss. By assigning annotations to hundreds of species-specific families, the functional diversity among species and between the major clades (Diptera and Hymenoptera) is revealed. We found that many species-specific families are associated with receptor signaling, stress-related functions and proteases. The highest variability among insects associates with the function of transposition and nucleic acids processes (collectively coined TNAP). Specifically, the wasp and ants have an order of magnitude more TNAP families and proteins relative to species that belong to Diptera (mosquitoes and flies). An unsupervised clustering methodology combined with a comparative functional analysis unveiled proteomic signatures in the major clades of winged insects. We propose that the expansion of TNAP families in Hymenoptera potentially contributes to the accelerated

Family violence is a social and public health issue across the world for many populations and affects many different types of people, for example, children, women, and vulnerable adults. Adolescents are one of the main victims of this important phenomenon. This article estimates the prevalence of family violence in adolescents and associated factors. The study was carried out in 2012 with a probability and representative sample of 656 adolescents aged between 11 and 17 years who were enrolled at public schools located in the extreme South of the city of São Paulo. The association was tested by the proportion test, Pearson's chi-square or Fischer's exact test, and Poisson regression adjusted by robust variance estimation, considering a level of significance of 5%. Among adolescents, 38.9% reported having been victims of family violence. Women were victimized with higher frequency (44.1%). The factors associated with prevalence of family violence were being of the female sex (prevalence ratio [PR] = 1.47; 95% confidence interval [CI] = [1.20, 1.80]) and living only with the father (PR = 1.52; 95% CI = [1.11, 2.08]). The prevalence of adolescents who were victims of family violence is high; however, special attention must be paid to women and adolescents who live only with their father-they were established, in this study, as a risk group. Epidemiological studies of this nature are important to reveal the reality of family violence and to aid the construction of intersectoral public policies to promote health, prevent violence, and foster a peaceful culture. © The Author(s) 2015.

OBJECTIVES: To identify risk and protective factors for family homelessness, a case-control study of homeless and low-income, never-homeless families, all female-headed, was conducted. METHODS: Homeless mothers (n = 220) were enrolled from family shelters in Worcester, Mass. Low-income housed mothers receiving welfare (n = 216) formed the comparison group. The women completed an interview covering socioeconomic, social support, victimization, mental health, substance use, and health domains. RESULTS: Childhood predictors of family homelessness included foster care placement and respondent's mother's use of drugs. Independent risk factors in adulthood included minority status, recent move to Worcester, recent eviction, interpersonal conflict, frequent alcohol or heroin use, and recent hospitalization for a mental health problem. Protective factors included being a primary tenant, receiving cash assistance or a housing subsidy, graduating from high school, and having a larger social network. CONCLUSIONS: Factors that compromise an individual's economic and social resources are associated with greater risk of losing one's home. PMID:9103104

Prior research has established that adolescents’ perceptions of family belonging are associated with a range of well-being indicators and that adolescents in stepfamilies report lower levels of family belonging than adolescents in two-biological-parent families. Yet, we know little regarding what factors are associated with adolescents’ perceptions of family belonging in stepfamilies. Guided by family systems theory, the authors addressed this issue by using nationally representative data (Add Health) to examine the associations between family characteristics and adolescents’ perceptions of family belonging in stepfather families (N = 2,085). Results from structural equation models revealed that both the perceived quality of the stepfather–adolescent relationship, and in particular the perceived quality of the mother–adolescent relationship, were the factors most strongly associated with feelings of family belonging.

Drought is one of the major threats to maize production. In order to improve the production and to breed tolerant hybrids, understanding the genes and regulatory mechanisms during drought stress is important. Transcription factors (TFs) play a major role in gene regulation and many TFs have been identified in response to drought stress. In our experiment, a set of 15 major TF families comprising 1436 genes was structurally and functionally characterized using in-silico tools and a gene expression assay. All 1436 genes were mapped on 10 chromosome of maize. The functional annotation indicated the involvement of these genes in ABA signaling, ROS scavenging, photosynthesis, stomatal regulation, and sucrose metabolism. Duplication was identified as the primary force in divergence and expansion of TF families. Phylogenetic relationship was developed individually for each TF family as well as combined TF families. Phylogenetic analysis grouped the TF family of genes into TF-specific and mixed groups. Phylogenetic analysis of genes belonging to various TF families suggested that the origin of TFs occurred in the lineage of maize evolution. Gene structure analysis revealed that more number of genes were intron-rich as compared to intronless genes. Drought-responsive CRE’s such as ABREA, ABREB, DRE1 and DRECRTCOREAT have been identified. Expression and interaction analyses identified leaf-specific bZIP TF, GRMZM2G140355, as a potential contributor toward drought tolerance in maize. We also analyzed protein-protein interaction network of 269 drought-responsive genes belonging to different drought-related TFs. The information generated on structural and functional characteristics, expression and interaction of the drought-related TF families will be useful to decipher the drought tolerance mechanisms and to derive drought-tolerant genotypes in maize.

WRKY transcription factors play an important role in cold defense of plants. However, little information is available about the cold-responsive WRKYs in tomato (Solanum lycopersicum). In the present study, a complete characterization of this gene family was described. Eighty WRKY genes in the tomato genome were identified. Almost all WRKY genes contain putative stress-responsive cis-elements in their promoter regions. Segmental duplications contributed significantly to the expansion of the SlWRKY gene family. Transcriptional analysis revealed notable differential expression in tomato tissues and expression patterns under cold stress, which indicated wide functional divergence in this family. Ten WRKYs in tomato were strongly induced more than 2-fold during cold stress. These genes represented candidate genes for future functional analysis of WRKYs involved in the cold-related signal pathways. Our data provide valuable information about tomato WRKY proteins and form a foundation for future studies of these proteins, especially for those that play an important role in response to cold stress.

Attention-deficit/hyperactivity disorder (ADHD) is associated with widespread cognitive impairments, but it is not known whether the apparent multiple impairments share etiological roots or separate etiological pathways exist. A better understanding of the etiological pathways is important for the development of targeted interventions and for identification of suitable intermediate phenotypes for molecular genetic investigations. To determine, by using a multivariate familial factor analysis approach, whether 1 or more familial factors underlie the slow and variable reaction times, impaired response inhibition, and choice impulsivity associated with ADHD. An ADHD and control sibling-pair design. Belgium, Germany, Ireland, Israel, Spain, Switzerland, and the United Kingdom. A total of 1265 participants, aged 6 to 18 years: 464 probands with ADHD and 456 of their siblings (524 with combined-subtype ADHD), and 345 control participants. Performance on a 4-choice reaction time task, a go/no-go inhibition task, and a choice-delay task. The final model consisted of 2 familial factors. The larger factor, reflecting 85% of the familial variance of ADHD, captured 98% to 100% of the familial influences on mean reaction time and reaction time variability. The second, smaller factor, reflecting 13% of the familial variance of ADHD, captured 62% to 82% of the familial influences on commission and omission errors on the go/no-go task. Choice impulsivity was excluded in the final model because of poor fit. The findings suggest the existence of 2 familial pathways to cognitive impairments in ADHD and indicate promising cognitive targets for future molecular genetic investigations. The familial distinction between the 2 cognitive impairments is consistent with recent theoretical models--a developmental model and an arousal-attention model--of 2 separable underlying processes in ADHD. Future research that tests the familial model within a developmental framework may inform

Phonological awareness, letter knowledge, oral language (including sentence recall) and rapid automatised naming are acknowledged within-child predictors of literacy development. Separate research has identified family factors including socio-economic status, parents' level of education and family history. However, both approaches have left unexplained significant amounts of variance in literacy outcomes. This longitudinal study sought to improve prospective classification accuracy for young children at risk of literacy failure by adding two new family measures (parents' phonological awareness and parents' perceived self-efficacy), and then combining the within-child and family factors. Pre-literacy skills were measured in 102 four year olds (46 girls and 56 boys) at the beginning of Preschool, and then at the beginning and end of Kindergarten, when rapid automatised naming was also measured. Family factors data were collected at the beginning of Preschool, and children's literacy outcomes were measured at the end of Year 1 (age 6-7 years). Children from high-risk backgrounds showed poorer literacy outcomes than low-risk students, though three family factors (school socio-economic status, parents' phonological awareness, and family history) typically accounted for less Year 1 variance than the within-child factors. Combining these family factors with the end of Kindergarten within-child factors provided the most accurate classification (i.e., sensitivity = .85; specificity = .90; overall correct = .88). Our approach would identify at-risk children for intervention before they began to fail. Moreover, it would be cost-effective because although few at-risk children would be missed, allocation of unnecessary educational resources would be minimised.

Auxin response factors (ARFs) are an important family of proteins in auxin-mediated response, with key roles in various physiological and biochemical processes. To date, a genome-wide overview of the ARF gene family in citrus was not available. A systematic analysis of this gene family in citrus was begun by carrying out a genome-wide search for the homologs of ARFs. A total of 19 nonredundant ARF genes (CiARF) were found and validated from the sweet orange. A comprehensive overview of the CiARFs was undertaken, including the gene structures, phylogenetic analysis, chromosome locations, conserved motifs of proteins, and cis-elements in promoters of CiARF. Furthermore, expression profiling using real-time PCR revealed many CiARF genes, albeit with different patterns depending on types of tissues and/or developmental stages. Comprehensive expression analysis of these genes was also performed under two hormone treatments using real-time PCR. Indole-3-acetic acid (IAA) and N-1-napthylphthalamic acid (NPA) treatment experiments revealed differential up-regulation and down-regulation, respectively, of the 19 citrus ARF genes in the callus of sweet orange. Our comprehensive analysis of ARF genes further elucidates the roles of CiARF family members during citrus growth and development process. PMID:25870601

To investigate the influence of consanguineous marriage on male factor infertility in Lebanon, where rates of consanguineous marriage remain high (29.6% among Muslims, 16.5% among Christians). Clinic-based, case-control study, using reproductive history, risk factor interview, and laboratory-based semen analysis. Two IVF clinics in Beirut, Lebanon, during an 8-month period (January-August 2003). One hundred twenty infertile male patients and 100 fertile male controls, distinguished by semen analysis and reproductive history. None. Standard clinical semen analysis. The rates of consanguineous marriage were relatively high among the study sample. Patients (46%) were more likely than controls (37%) to report first-degree (parental) and second-degree (grandparental) consanguinity. The study demonstrated a clear pattern of family clustering of male factor infertility, with patients significantly more likely than controls to report infertility among close male relatives (odds ratio = 2.58). Men with azoospermia and severe oligospermia showed high rates of both consanguinity (50%) and family clustering (41%). Consanguineous marriage is a socially supported institution throughout the Muslim world, yet its relationship to infertility is poorly understood. This study demonstrated a significant association between consanguinity and family clustering of male factor infertility cases, suggesting a strong genetic component.

Given the important role of family environment in children's psychological development, the objective of this study was to examine the linkages between family factors at the whole, dyadic, and individual levels and two dimensions (affective and behavioral) of Oppositional Defiant Disorder (ODD) symptoms in Chinese children. Participants comprised of 80 father-child dyads and 169 mother-child dyads from families with ODD children. The results indicated that multilevel family factors were differently associated with children's affective and behavioral ODD symptoms. All the family factors at the dyadic and individual levels were significantly associated with child affective ODD symptoms. However, only the most proximal factors (parent-child relationship and child emotion regulation, which were directly related to child) were significantly related to child behavioral ODD symptoms. The present study extends the current knowledge regarding the relationships between family factors and two dimensions of child ODD symptoms by testing the comprehensive multilevel family factors model. This study also recommends that future interventions for ODD children should consider the multi-level family factors to enhance intervention efficacy. PMID:28713321

There is broad agreement that neighborhood contexts are important for adolescent development, but there is less consensus about their association with adolescent smoking and alcohol use. Few studies have examined associations between neighborhood socioeconomic contexts and smoking and alcohol use while also accounting for differences in family and peer risk factors for substance use. Data drawn from the Seattle Social Development Project (N = 808), a gender-balanced (female = 49%), multiethnic, theory-driven longitudinal study originating in Seattle, WA, were used to estimate trajectories of smoking and alcohol use from 5th to 9th grade. Time-varying measures of neighborhood socioeconomic, family, and peer factors were associated with smoking and alcohol use at each wave after accounting for average growth in smoking and alcohol use over time and demographic differences. Results indicated that living in more socioeconomically disadvantaged neighborhoods, lower family income, lower family general functioning, more permissive family smoking environments, and affiliation with deviant peers were independently associated with increased smoking. Lower family functioning, more permissive family alcohol use environments, and deviant peers were independently associated with increased alcohol use. The effect of neighborhood disadvantage on smoking was mediated by family income and deviant peers while the effect of neighborhood disadvantage on alcohol use was mediated by deviant peers alone. Family functioning and family substance use did not mediate associations between neighborhood disadvantage and smoking or alcohol use. The results highlight the importance of neighborhood, family, and peer factors in early adolescent smoking and alcohol use. Future studies should examine the unique association of neighborhood disadvantage with adolescent smoking net of family socioeconomics, functioning, and substance use, as well as peer affiliations.

To examine factors associated with children's body mass index and obesity-risk behaviours in Korean American families. Limited data are available about family factors related to overweight and obesity in Korean American children. A cross-sectional study. Convenient sampling was employed to recruit Korean American families in the Northeast of the United States between August 2014 and January 2015. Child, family and societal/demographic/community factors were measured with self-report questionnaires completed by mothers and children. Height and weight were measured to calculate body mass index. Data were analyzed using mixed effects models incorporating within-group correlation in siblings. The sample included 170 Korean American children and 137 mothers. In bivariate analyses, more child screen time, number of children in the household, greater parental underestimation of child's weight and children's participation in the school lunch program were significantly associated with higher child body mass index. In multivariate analyses that included variables showing significant bivariate relationship, no variable was associated with child body mass index. There were no child, family and societal/demographic/community factors related to child body mass index in Korean American families in the multivariate analysis, which is contrary to research in other racial/ethnic groups. In bivariate analyses, there is evidence that some factors were significantly related to child body mass index. Further research is needed to understand the unique behavioural, social and cultural features that contribute to childhood obesity in Korean American families. © 2017 John Wiley & Sons Ltd.

Support groups fill a critical void in the health care system, harnessing the power of shared experiences to provide support to group members. Likewise, family caregivers fill a void in the health care system, providing billions in unpaid care to the chronically ill. Caregiver support groups offer an opportunity for alleviating the psychological burden of caregiving. The power of any group, including a support group, to foster psychological well-being lies in its ability to cultivate Yalom's therapeutic factors. Gaps in the literature remain regarding the ability of non-prototypical groups to promote therapeutic mechanisms of change. The purpose of this study was to determine if and when Yalom's therapeutic group factors emerged in a peer-led support group delivered in an asynchronous, online format. Qualitative content analysis utilizing deductive category application was employed. Participants' responses were coded and frequency counts were conducted. Results revealed that 9 of 11 therapeutic factors emerged over the course of the group, with Group Cohesiveness, Catharsis, Imparting of Information, and Universality occurring most often. Several factors, including Interpersonal Learning, Corrective Recapitulation of the Primary Family Group, Imitative Behavior, and Development of Socializing Techniques were absent or virtually absent, likely due to the peer-led format of the group. Progression of therapeutic factors over the course of the group is presented. Findings demonstrate the presence of a variety of Yalom's therapeutic factors in an asynchronous, peer-led online support group.

The lentiviral protein Viral Infectivity Factor (Vif) counteracts the antiviral effects of host APOBEC3 (A3) proteins and contributes to persistent HIV infection. Vif targets A3 restriction factors for ubiquitination and proteasomal degradation by recruiting them to a multi-protein ubiquitin E3 ligase complex. Here, we describe a degradation-independent mechanism of Vif-mediated antagonism that was revealed through detailed structure-function studies of antibody antigen-binding fragments (Fabs) to the Vif complex. Two Fabs were found to inhibit Vif-mediated A3 neutralization through distinct mechanisms: shielding A3 from ubiquitin transfer and blocking Vif E3 assembly. Combined biochemical, cell biological and structural studies reveal that disruption of Vif E3 assembly inhibited A3 ubiquitination but was not sufficient to restore its packaging into viral particles and antiviral activity. These observations establish that Vif can neutralize A3 family members in a degradation-independent manner. Additionally, this work highlights the potential of Fabs as functional probes, and illuminates how Vif uses a multi-pronged approach involving both degradation dependent and independent mechanisms to suppress A3 innate immunity.

Family and school environments are assumed to be associated with and influence aggressive behaviors. However, which specific risk factors within these environments that are associated with aggressive behavior are unclear. The goal of this study is to identify family and social environmental qualities that are related to aggression among Chinese adolescents. Survey data were obtained from 3,213 randomly selected urban high school students ages 10 through 18 in southern China. Lower parental attachment, higher family income, mother's higher education levels, father's parenting goals, rough or changeable parenting styles, unsuitable peer relationships, and inadequate social atmospheres at school serve as risk factors for aggression among Chinese adolescents. Our findings provide some implications for understanding aggression among adolescents and suggests possible interventions to help overcome potential environmental risk factors and thus to prevent aggressive behavior in school.

The co-occurrence of type 2 diabetes and psychosis is an important form of medical comorbidity within individuals, but no large-scale study has evaluated comorbidity within families. The aim of this study was to determine whether there is evidence for familial comorbidity between type 2 diabetes and psychosis. Data were analysed from an observational study of a nationally representative sample of 1642 people with psychosis who were in contact with psychiatric services at the time of survey (The 2010 Australian National Survey of Psychosis). Participants were aged 18-64 years and met World Health Organization's International Classification of Diseases, 10th Revision diagnostic criteria for a psychotic disorder (857 with schizophrenia, 319 with bipolar disorder with psychotic features, 293 with schizoaffective disorder, 81 with depressive psychosis and 92 with delusional disorder or other non-organic psychoses). Logistic regression was used to estimate the association between a family history of diabetes and a family history of schizophrenia. A positive family history of diabetes was associated with a positive family history of schizophrenia in those with a psychotic disorder (odds ratio = 1.35, p = 0.01, adjusted for age and gender). The association was different in those with an affective versus non-affective psychosis (odds ratio = 0.613, p = 0.019, adjusted for age and gender) and was significant only in those with a non-affective psychosis, specifically schizophrenia (odds ratio = 1.58, p = 0.005, adjusted for age and sex). Adjustment for demographic factors in those with schizophrenia slightly strengthened the association (odds ratio = 1.74, p = 0.001, adjusted for age, gender, diagnosis, ethnicity, education, employment, income and marital status). Elevated risk for type 2 diabetes in people with schizophrenia is not simply a consequence of antipsychotic medication; type 2 diabetes and schizophrenia share familial risk factors. © The Royal Australian and New

ABSTRACT Objective: to analyze the factors associated with young adults' knowledge regarding family history of stroke. Method: an analytical transversal study, with 579 young adults from state schools, with collection of sociodemographic, clinical and risk factor-related variables, analyzed using logistic regression (backward elimination). Results: a statistical association was detected between age, civil status, and classification of arterial blood pressure and abdominal circumference with knowledge of family history of stroke. In the final logistic regression model, a statistical association was observed between knowledge regarding family history of stroke and the civil status of having a partner (ORa=1.61[1.07-2.42]; p=0.023), abdominal circumference (ORa=0.98[0.96-0.99]; p=0.012) and normal arterial blood pressure (ORa=2.56[1.19-5.52]; p=0.016). Conclusion: an association was observed between socioeconomic factors and risk factors for stroke and knowledge of family history of stroke, suggesting the need for health education or even educational programs on this topic for the clientele in question.

To explore the similarities and differences in factors that influence nurses' and physicians' decision-making related to family presence during resuscitation. Despite the growing acceptance of family presence during resuscitation worldwide, healthcare professionals continue to debate the risks and benefits of family presence. As many hospitals lack a policy to guide family presence during resuscitation, decisions are negotiated by resuscitation teams, families and patients in crisis situations. Research has not clarified the factors that influence the decision-making processes of nurses and physicians related to inviting family presence. This is the first study to elicit written data from healthcare professionals to explicate factors in decision-making about family presence. Qualitative exploratory-descriptive. Convenience samples of registered nurses (n = 325) and acute care physicians (n = 193) from a Midwestern hospital in the United States of America handwrote responses to open-ended questions about family presence. Through thematic analysis, decision-making factors for physicians and nurses were identified and compared. Physicians and nurses evaluated three similar factors and four differing factors when deciding to invite family presence during resuscitation. Furthermore, nurses and physicians weighted the factors differently. Physicians weighted most heavily the family's potential to disrupt life-saving efforts and compromise patient care and then the family's knowledge about resuscitations. Nurses heavily weighted the potential for the family to be traumatised, the potential for the family to disrupt the resuscitation, and possible family benefit. Nurses and physicians considered both similar and different factors when deciding to invite family presence. Physicians focused on the patient primarily, while nurses focused on the patient, family and resuscitation team. Knowledge of factors that influence the decision-making of interprofessional colleagues

Molecular genetic analysis of familial and non-familial cases of conventional renal cell carcinoma (RCC) revealed a critical role(s) for multiple genes on human chromosome 3. For some of these genes, e.g. VHL, such a role has been firmly established, whereas for others, definite confirmation is still pending. Additionally, a novel role for constitutional chromosome 3 translocations as risk factors for conventional RCC development is rapidly emerging. Also, several candidate loci have been mapped to other chromosomes in both familial and non-familial RCCs of distinct histologic subtypes. The MET gene on chromosome 7, for example, was found to be involved in both forms of papillary RCC. A PRCC-TFE3 fusion gene is typically encountered in t(X;1)-positive non-familial papillary RCCs and results in abrogation of the cell cycle mitotic spindle checkpoint in a dominant-negative fashion, thus leading to RCC. Together, these data turn human RCC into a model system in which different aspects of both familial and non-familial syndromes may act as novel paradigms for cancer development.

As the number of dual-earner couples in Japan has increased, work-life balance has become important. This study aimed to examine the factors that contribute to work-family conflict. The participants included 3,594 (2,332 men and 1,262 women) civil servants aged 20-59 working for local government on the west coast of Japan. Logistic regression analysis was used to evaluate whether work, family, or lifestyle characteristics were associated with work-family conflict. For men, family-to-work conflict was associated with being elderly, having low-grade employment, working long hours, raising children, and sleeping shorter hours. For women, being married and raising children were strong determinants of family-to-work conflict, and being middle-aged, working long hours, and sleeping shorter hours were also associated with this type of conflict. Regarding work-to-family conflict, working long hours was the strongest determinant of conflict in both sexes. In men, being elderly, living with family, eating dinner late, and sleeping shorter hours were also associated with work-to-family conflict. In women, having high-grade employment, being married, raising children, and eating dinner late were associated with work-to-family conflict. This study showed that working long hours was the primary determinant of work-to-family conflict in both sexes and that being married and raising children were strong factors of family-to-work conflict in women only. Sex differences may reflect divergence of the social and domestic roles of men and women in Japanese society. To improve the work-life balance, general and sex-specific health policies may be required.

2014-01-01

MYB family genes are widely distributed in plants and comprise one of the largest transcription factors involved in various developmental processes and defense responses of plants. To date, few MYB genes and little expression profiling have been reported for citrus. Here, we describe and classify 177 members of the sweet orange MYB gene (CsMYB) family in terms of their genomic gene structures and similarity to their putative Arabidopsis orthologs. According to these analyses, these CsMYBs were categorized into four groups (4R-MYB, 3R-MYB, 2R-MYB and 1R-MYB). Gene structure analysis revealed that 1R-MYB genes possess relatively more introns as compared with 2R-MYB genes. Investigation of their chromosomal localizations revealed that these CsMYBs are distributed across nine chromosomes. Sweet orange includes a relatively small number of MYB genes compared with the 198 members in Arabidopsis, presumably due to a paralog reduction related to repetitive sequence insertion into promoter and non-coding transcribed region of the genes. Comparative studies of CsMYBs and Arabidopsis showed that CsMYBs had fewer gene duplication events. Expression analysis revealed that the MYB gene family has a wide expression profile in sweet orange development and plays important roles in development and stress responses. In addition, 337 new putative microsatellites with flanking sequences sufficient for primer design were also identified from the 177 CsMYBs. These results provide a useful reference for the selection of candidate MYB genes for cloning and further functional analysis forcitrus. PMID:25375352

Genetic liability, prenatal health, stress and family environment: risk factors in the Harvard Adolescent Family High Risk for schizophrenia study.

The familial ("genetic") high-risk (FHR) paradigm enables assessment of individuals at risk for schizophrenia based on a positive family history of schizophrenia in first-degree, biological relatives. This strategy presumes genetic transmission of abnormal traits given high heritability of the illness. It is plausible, however, that adverse environmental factors are also transmitted in these families. Few studies have evaluated both biological and environmental factors within a FHR study of adolescents. We conceptualize four precursors to psychosis pathogenesis: two biological (genetic predisposition, prenatal health issues (PHIs)) and two environmental (family environment, stressful life events (SLEs)). Participants assessed between 1998 and 2007 (ages 13-25) included 40 (20F/20M) adolescents at FHR for schizophrenia (FHRs) and 55 (31F/24M) community controls. 'Genetic load' indexed number of affected family members relative to pedigree size. PHI was significantly greater among FHRs, and family cohesion and expressiveness were less (and family conflict was higher) among FHRs; however, groups did not significantly differ in SLE indices. Among FHRs, genetic liability was significantly associated with PHI and family expressiveness. Prenatal and family environmental disruptions are elevated in families with a first-degree relative with schizophrenia. Findings support our proposed 'polygenic neurodevelopmental diathesis-stress model' whereby psychosis susceptibility (and resilience) involves the independent and synergistic confluence of (temporally-sensitive) biological and environmental factors across development. Recognition of biological and social environmental influences across critical developmental periods points to key issues relevant for enhanced identification of psychosis susceptibility, facilitation of more precise models of illness risk, and development of novel prevention strategies.

ABFs, a family of ABA-responsive element binding factors.

PubMed

Choi, H; Hong, J; Ha, J; Kang, J; Kim, S Y

2000-01-21

Abscisic acid (ABA) plays an important role in environmental stress responses of higher plants during vegetative growth. One of the ABA-mediated responses is the induced expression of a large number of genes, which is mediated by cis-regulatory elements known as abscisic acid-responsive elements (ABREs). Although a number of ABRE binding transcription factors have been known, they are not specifically from vegetative tissues under induced conditions. Considering the tissue specificity of ABA signaling pathways, factors mediating ABA-dependent stress responses during vegetative growth phase may thus have been unidentified so far. Here, we report a family of ABRE binding factors isolated from young Arabidopsis plants under stress conditions. The factors, isolated by a yeast one-hybrid system using a prototypical ABRE and named as ABFs (ABRE binding factors) belong to a distinct subfamily of bZIP proteins. Binding site selection assay performed with one ABF showed that its preferred binding site is the strong ABRE, CACGTGGC. ABFs can transactivate an ABRE-containing reporter gene in yeast. Expression of ABFs is induced by ABA and various stress treatments, whereas their induction patterns are different from one another. Thus, a new family of ABRE binding factors indeed exists that have the potential to activate a large number of ABA/stress-responsive genes in Arabidopsis.

This paper examines selected factors affecting the acceptance and delivery of modern family planning from health centres in Manus. A survey was carried out of mothers attending Maternal and Child Health clinics and a written questionnaire was given to health workers. The survey of mothers demonstrated the importance of the husband's approval for contraceptive practice and showed that knowledge about traditional methods of family planning is widespread. The health workers' questionnaire demonstrated a high level of dissatisfaction with the current family planning program delivered by health clinics: 45% found the program ineffective; 68% wrote that health workers' attitudes discouraged mothers from attending for family planning. The perceived and actual benefits and costs of children and the role of men should be assessed locally before planning future family planning programs. Widespread retraining and motivating of health workers is essential if improved coverage is to be achieved through health services. The efficacy of alternative methods of delivery of family planning such as local community-based and social marketing programs should also be investigated.

We examined the factors that affect suicide attempts adolescents multicultural families in South Korea. The participants were 727 adolescents whose mothers and/or fathers were born outside of South Korea (376 males and 351 females). Among them, 41 (weighted prevalence 6.2%) had attempted suicide during the last 12 months. Female gender, residence in large cities (compared with in rural areas), living with relatives/alone/with friends/in a dormitory or living in a facility (compared with living with family), high and low socio-economic status (compared with a middle level), high and low academic performance (compared with a middle level), severe perceived stress (compared with non-severe stress), conflicts with a teacher (compared with conflicts with parent), and foreign-father/-parent families (compared with foreign-mother family) were associated with increased odds of suicide attempt. The results indicate that greater awareness of the possibility of suicidal behavior is prudent for adolescents in multicultural families with certain risk factors, such as being from a foreign-parents family, living separately from the family, and having conflicts with a teacher.

Family history contributes to risk for many common chronic diseases. Little research has investigated patient factors affecting communication of this information. 1061 adult community health center patients were surveyed. We examined factors related to frequency of discussions about family health history (FHH) with family members and doctors. Patients who talked frequently with family members about FHH were more likely to report a family history of cancer (p =.012) and heart disease (p < .001), seek health information frequently in newspapers (p < .001) and in general (p < .001), and be female (p < .001). Patients who talked frequently with doctors about FHH were more likely to report a family history of heart disease (p = .011), meet physical activity recommendations (p = .022), seek health information frequently in newspapers (p < .001) and in general (p < .001), be female (p < .001), and not have experienced racial discrimination in healthcare (p < .001). Patients with a family history of some diseases, those not meeting physical activity recommendations, and those who do not frequently seek health information may not have ongoing FHH discussions. Interventions are needed to encourage providers to update patients' family histories systematically and assist patients in initiating FHH conversations in order to use this information for disease prevention and control.

Children's disaster reactions: the influence of family and social factors.

PubMed

Pfefferbaum, Betty; Jacobs, Anne K; Houston, J Brian; Griffin, Natalie

2015-07-01

This review examines family (demographics, parent reactions and interactions, and parenting style) and social (remote effects, disaster media coverage, exposure to secondary adversities, and social support) factors that influence children's disaster reactions. Lower family socioeconomic status, high parental stress, poor parental coping, contact with media coverage, and exposure to secondary adversities have been associated with adverse outcomes. Social support may provide protection to children in the post-disaster environment though more research is needed to clarify the effects of certain forms of social support. The interaction of the factors described in this review with culture needs further exploration.

Active commuting to school is associated to higher levels of physical activity among children. Family factors may influence on this behaviour. The objective was to analyze the association between parents' occupational activity and parents' mode of commuting to work with the mode of commuting of their children. A total of 721 families from 4 primary schools in the province of Granada participated in this study. Families reported a questionnaire about mode of commuting of their children, parents' occupational activity and mode of commuting to work, distance and travel time to school. Associations between family's occupational activity and mode of commuting to work with mode of commuting to school of their children were examined using binary logistic regression analysis adjusting for age and children's distance to school. Children whose parents did not work used to engage in higher levels of active commuting to school than those whose parents worked (p = 0,023; OR: 2,67; 95% CI: 1,14-6,23). Children whose parents used to commute actively to work used to engage in higher levels of active commuting to school than those whose parents both used passive modes of commuting to work (p = 0,014; OR: 6,30; 95% CI: 1,45-27,26). Family factors are related to mode of commuting to school in children: Unemployed families and employed families where parent are active commuters to work are more used to have children that commuted to school using active modes.

The aim of the study was the determination of the relationships between neurophysiological and psychosocial factors within the pathogenesis of migraine. The contingent negative variation (CNV), parent-child interactions and theirs relationship were investigated in 30 families with a migraine child and 20 healthy families. (1) None of the groups of children, independent of diagnosis, differed according to amplitude or habituation of the CNV. (2) Parents from migraine families exerted significantly more control over migraine children compared with interactions with healthy brothers/sisters. (3) The strong relation between CNV habituation/amplitude and abnormal pattern of parent-child interactions (especially overwhelming dominance and control) was found only for young migraineurs. This relation was not seen in healthy families or for healthy siblings of migraine children. This study provides significant evidence for a strong influence of family interactions on the development and maintenance of neurophysiological abnormalities in the migraineous headache. The role of psychosocial factors in the etiopathogenesis of migraine has to be investigated in further studies in more detail.

Factors determining family planning in Catalonia. Sources of inequity

Introduction In recent decades, the foreign population in Spain has increased significantly, particularly for Catalonia, an autonomous region of Spain (2.90% in 2000 and 15.95% in 2010) and in particular Girona province (6.18% in 2000 and 21.55% in 2010). Several studies have shown a lower use of family planning methods by immigrants. This same trend is observed in Spain. The objective of this paper is to determine the existence of differences and possible sources of inequity in the use of family planning methods among health service users in Catalonia (Spain) by sex, health status, place of birth and socioeconomic conditions. Methods Data were taken from an ad-hoc questionnaire which was compiled following a qualitative stage of individual interviews. Said questionnaire was administered to 1094 Catalan public health service users during 2007. A complete descriptive analysis was carried out for variables related to public health service users’ sociodemographic characteristics and variables indicating knowledge and use of family planning methods, and bivariate relationships were analysed by means of chi-square contrasts. Considering the use (or non-use) of family planning methods as a dependent variable and a set of demographic, socioeconomic and health status variables as explanatory factors, the relationship was modelled using mixed models. Results The analysed sample is comprised of 54.3% women and 45.7% men, with 74.3% natives (or from the EU) and 25.7% economic immigrants. 54.8% use some method of family planning, the condom (46.7%) and the pill (28.0%) being the two most frequently used methods. Statistical modelling indicates that those factors which most influence the use of family planning methods are level of education (30.59% and 39.29% more likelihood) and having children over 14 (35.35% more likelihood). With regard to the origin of the user, we observe that patients from North Africa,sub. Saharan Africa and Asia are less likely to use family planning

Plant pathogen Xanthomonas campestris pv. campestris produces cis-11-methyl-2-dodecenoic acid (diffusible signal factor [DSF]) as a cell-cell communication signal to regulate biofilm dispersal and virulence factor production. Previous studies have demonstrated that DSF biosynthesis is dependent on the presence of RpfF, an enoyl-coenzyme A (CoA) hydratase, but the DSF synthetic mechanism and the influence of the host plant on DSF biosynthesis are still not clear. We show here that exogenous addition of host plant juice or ethanol extract to the growth medium of X. campestris pv. campestris could significantly boost DSF family signal production. It was subsequently revealed that X. campestris pv. campestris produces not only DSF but also BDSF (cis-2-dodecenoic acid) and another novel DSF family signal, which was designated DSF-II. BDSF was originally identified in Burkholderia cenocepacia to be involved in regulation of motility, biofilm formation, and virulence in B. cenocepacia. Functional analysis suggested that DSF-II plays a role equal to that of DSF in regulation of biofilm dispersion and virulence factor production in X. campestris pv. campestris. Furthermore, chromatographic separation led to identification of glucose as a specific molecule stimulating DSF family signal biosynthesis in X. campestris pv. campestris. 13C-labeling experiments demonstrated that glucose acts as a substrate to provide a carbon element for DSF biosynthesis. The results of this study indicate that X. campestris pv. campestris could utilize a common metabolite of the host plant to enhance DSF family signal synthesis and therefore promote virulence.

Maternal and family factors and child eating pathology: risk and protective relationships

PubMed Central

2014-01-01

Background Previous studies have found associations between maternal and family factors and child eating disorder symptoms. However, it is not clear whether family factors predict eating disorder symptoms specifically, or relate to more general child psychopathology, of which eating disorder symptoms may be one component. This study aimed to identify maternal and family factors that may predict increases or decreases in child eating disorder symptoms over time, accounting for children’s body mass index z-scores and levels of general psychological distress. Methods Participants were 221 mother-child dyads from the Childhood Growth and Development Study, a prospective cohort study in Western Australia. Participants were assessed at baseline, 1-year follow-up and 2-year follow-up using interview and self-report measures. Children had a mean age of 10 years at baseline and 46% were male. Linear mixed models and generalised estimating equations were used to identify predictors of children’s eating disorder symptoms, with outcome variables including a global index of eating disorder psychopathology, levels of dietary restraint, levels of emotional eating, and the presence of loss of control (‘binge’) eating. Results Children of mothers with a current or past eating disorder reported significantly higher levels of global eating disorder symptoms and emotional eating than other children, and mothers with a current or past eating disorder reported significantly more concern about their children’s weight than other mothers. Maternal concern about child weight, rather than maternal eating disorder symptoms, was significant in predicting child eating disorder symptoms over time. Family exposure to stress and low maternal education were additional risk factors for eating disorder symptoms, whilst child-reported family satisfaction was a protective factor. Conclusions After adjusting for relevant confounding variables, maternal concern about child weight, children�

The aim of this research is to look into the roles of families' social situation and cohesion in adolescent auto-aggressiveness in Croatia. The research was conducted on a sample of Zagreb high school students which encompassed 701 pupils of both genders aged 14-19. The basic demographic data were obtained using the Structured Demographic and Family Data Questionnaire. Auto-aggressiveness was tested using a section of the Report on Youth Aged 11-18 and the Scale of Auto-destructiveness--SAD, whereas the family cohesion was tested with the Family Adaptability and Cohesion Evaluation Scales FACES III. The obtained results show differences according to the gender: girls are more prone to auto-aggressiveness than boys (t = -3.385, df = 565, p = 0.001) and girls more often show symptoms of destructiveness (t = -3.809, df = 637, p < 0.001) and anxiety (t = -6.562, df = 640, p < 0.001), while boys show pronounced aggressiveness (t = 2.655, df = 653, p = 0.008). Significant family factors associated with auto-aggressiveness are parents' marital status (chi2 = 18.039, df = 4, p = 0.001), their financial situation (F(2.548) = 4.604, p = 0.010), alcoholic father (chi2 = 9.270, df = 2, p = 0.010), mentally ill mother (t = 5.264, df = 541, p < 0.001), as well as mentally ill father (t = 4.744, df = 529, p < 0.001), and corporal punishment by mother (F(2.542) = 8.132, p < 0.001) or father (F(2.530) = 5.341, p = 0.005). Adolescents from split families show more auto-aggressiveness. Family cohesion appears to be considerably associated with auto-aggressiveness and the adolescents that see their families as less cohesive have more mental problems (chi2 = 29.98, df = 2, p < 0.001). There is a connection between auto-destructive behavior in adolescents and family factors. Knowledge of family's social situation and cohesion may help understand, prevent and treat auto-aggressiveness in adolescents.

As the second largest transcription factor family in plant, the basic helix-loop-helix (bHLH) transcription factor family, characterized by the conserved bHLH domain, plays a central regulatory role in many biological process. However, the bHLH transcription factor family of strawberry has not been systematically identified, especially for the anthocyanin biosynthesis. Here, we identified a total of 113 bHLH transcription factors and described their chromosomal distribution and bioinformatics for the diploid woodland strawberry Fragaria vesca. In addition, transcription profiles of 113 orthologous bHLH genes from various tissues were analyzed for the cultivar 'Benihoppe', its white-flesh mutant 'Xiaobai', and the 'Snow Princess' from their fruit development to the ripening, as well as those under either the ABA or Eth treatment. Both the RT-PCR and qRT-PCR results show that seven selected FabHLH genes (FabHLH17, FabHLH25, FabHLH27, FabHLH29, FabHLH40, FabHLH80, FabHLH98) are responsive to the fruit anthocyanin biosynthesis and hormone signaling according to transcript profiles where three color modes are observed for strawberry's fruit skin and flesh. Further, prediction for the protein interaction network reveals that four bHLHs (FabHLH25, FabHLH29, FabHLH80, FabHLH98) are involved in the fruit anthocyanin biosynthesis and hormone signaling transduction. These bioinformatics and expression profiles provide a good basis for a further investigation of strawberry bHLH genes.

MADS-box transcription factors play significant roles in plant developmental processes such as floral organ conformation, flowering time, and fruit development. Pear ( Pyrus ), as the third-most crucial temperate fruit crop, has been fully sequenced. However, there is limited information about the MADS family and its functional divergence in pear. In this study, a total of 95 MADS-box genes were identified in the pear genome, and classified into two types by phylogenetic analysis. Type I MADS-box genes were divided into three subfamilies and type II genes into 14 subfamilies. Synteny analysis suggested that whole-genome duplications have played key roles in the expansion of the MADS family, followed by rearrangement events. Purifying selection was the primary force driving MADS-box gene evolution in pear, and one gene pairs presented three codon sites under positive selection. Full-scale expression information for PbrMADS genes in vegetative and reproductive organs was provided and proved by transcriptional and reverse transcription PCR analysis. Furthermore, the PbrMADS11(12) gene, together with partners PbMYB10 and PbbHLH3 was confirmed to activate the promoters of the structural genes in anthocyanin pathway of red pear through dual luciferase assay. In addition, the PbrMADS11 and PbrMADS12 were deduced involving in the regulation of anthocyanin synthesis response to light and temperature changes. These results provide a solid foundation for future functional analysis of PbrMADS genes in different biological processes, especially of pigmentation in pear.

This study aims to explore possible risk factors for child maltreatment in Vietnam by investigating the association of child and family factors with different types of child maltreatment (i.e., sexual abuse, physical abuse, emotional abuse, witnessing parental conflict, and neglect) and the occurrence of multiple types of child maltreatment. Cross-sectional data of 1,851 secondary and high school students aged 12 to 17 years (47.3% boys) in four provinces of Northern Vietnam were obtained using self-report questionnaires. Results indicated that the likelihood of emotional abuse, witnessing parental conflict, and experiencing multiple types of child maltreatment during lifetime increased with age. Boys had a higher risk than girls on lifetime sexual abuse, and past year and lifetime physical abuse. Living in a single parent family was the risk factor related to most types of child maltreatment including lifetime sexual abuse, neglect, and multiple types of child maltreatment, and both past year and lifetime witnessing parental conflict. Interestingly, low socioeconomic status (SES) and parental unemployment were associated with a decreased risk on experiencing emotional abuse in the past year and during lifetime, respectively. "Tiger parenting," a parenting style observed frequently in East Asian parents, may be more common in families with high SES and might explain this finding. This study highlights the importance of prioritizing single parent families in parenting programs and implementing child maltreatment interventions early because of the risk on child maltreatment increased with age. More research on emotional abuse and "Tiger parenting" in Vietnam could clarify the association of emotional abuse with high SES and parental employment. Finally, the underlying mechanisms of the risk factors in Vietnam should be studied more to inform interventions.

Transcription factors (TFs) play essential roles in the regulatory networks controlling many developmental processes in plants. Members of the basic leucine (Leu) zipper (bZIP) TF family, which is unique to eukaryotes, are involved in regulating diverse processes, including flower and vascular development, seed maturation, stress signaling, and defense responses to pathogens. The bZIP proteins have a characteristic bZIP domain composed of a DNA-binding basic region and a Leu zipper dimerization region. In this study, we identified 112 apple (Malus domestica Borkh) bZIP TF-encoding genes, termed MdbZIP genes. Synteny analysis indicated that segmental and tandem duplication events, as well as whole genome duplication, have contributed to the expansion of the apple bZIP family. The family could be divided into 11 groups based on structural features of the encoded proteins, as well as on the phylogenetic relationship of the apple bZIP proteins to those of the model plant Arabidopsis thaliana (AtbZIP genes). Synteny analysis revealed that several paired MdbZIP genes and AtbZIP gene homologs were located in syntenic genomic regions. Furthermore, expression analyses of group A MdbZIP genes showed distinct expression levels in 10 different organs. Moreover, changes in these expression profiles in response to abiotic stress conditions and various hormone treatments identified MdbZIP genes that were responsive to high salinity and drought, as well as to different phytohormones.

The stress associated with a career in emergency medical services (EMS) can impact the work-family fit and function of the family system for EMS personnel. Little research has been conducted on how the demands associated with a career in EMS influences family life. Objective. To describe salient EMS work factors that can impact the family system. Twelve family members (11 spouses and one parent) of EMS workers were interviewed using a semistructured qualitative interview guide that explored issues related to their family members' work that could impact the quality of family life. Using a phenomenological approach, transcribed interview data were examined for themes that illuminated factors that influence work-family fit. Data analysis revealed that shift work impacts numerous aspects of family life, including marital and parental roles, leisure and social opportunities, and home schedules and rhythms. Furthermore, families coped with challenges associated with their loved one's EMS work through negotiating role responsibilities, developing their own interests, giving their family member "space," and providing support by listening and helping the EMS worker process his or her reactions to difficult work. In addition, family members reported concern over their EMS worker's physical safety. Implications from the data are discussed vis-a-vis the work-family fit and family systems models. Education, communication, support systems, and individual interests are key ways to promote a healthy work-family fit.

OBJECTIVES: to adapt and validate the Inventory of Family Protective Factors (IFPF) for the Portuguese culture. This instrument assesses protective factors that contribute to family resilience. Studies addressing resilience are embedded within the salutogenic paradigm, i.e. it addresses protective factors of individuals or groups without underestimating risk factors or vulnerability. METHOD: in order to assess the IFPF's linguistic and conceptual equivalence, the instrument was translated, retro-translated and the think-aloud protocol was used. We then verified the instrument's sensitiveness, reliability and validity of results to assess its psychometric characteristics. A factor analysis was performed of the principal components with varimax rotation of the scale's items and Cronbach's alpha coefficient was calculated for each dimension. A total of 85 families with disabled children, selected through simple random sampling, self-administered the instrument. RESULTS: the IFPF presents psychometric characteristics that are appropriate for the Portuguese population (Cronbach's alpha = .90). CONCLUSION: the IFPF was adapted and validated for the Portuguese culture and is an instrument to be used in studies intended to assess protective factors of family resilience. PMID:25591096

Rationale Phonological awareness, letter knowledge, oral language (including sentence recall) and rapid automatised naming are acknowledged within-child predictors of literacy development. Separate research has identified family factors including socio-economic status, parents’ level of education and family history. However, both approaches have left unexplained significant amounts of variance in literacy outcomes. This longitudinal study sought to improve prospective classification accuracy for young children at risk of literacy failure by adding two new family measures (parents’ phonological awareness and parents’ perceived self-efficacy), and then combining the within-child and family factors. Method Pre-literacy skills were measured in 102 four year olds (46 girls and 56 boys) at the beginning of Preschool, and then at the beginning and end of Kindergarten, when rapid automatised naming was also measured. Family factors data were collected at the beginning of Preschool, and children’s literacy outcomes were measured at the end of Year 1 (age 6–7 years). Results Children from high-risk backgrounds showed poorer literacy outcomes than low-risk students, though three family factors (school socio-economic status, parents’ phonological awareness, and family history) typically accounted for less Year 1 variance than the within-child factors. Combining these family factors with the end of Kindergarten within-child factors provided the most accurate classification (i.e., sensitivity = .85; specificity = .90; overall correct = .88). Implications Our approach would identify at-risk children for intervention before they began to fail. Moreover, it would be cost-effective because although few at-risk children would be missed, allocation of unnecessary educational resources would be minimised. PMID:24751691

This study examines differences in psychological adjustment in a sample of rural adolescents who have been exposed to family violence. Self-report questionnaires were administered to 580 adolescents and their primary caregivers. The results revealed that over two thirds of the study participants (68.8%) had been exposed to violence in their families. As hypothesized, cluster analysis identified several profiles among adolescents, distinguished by their psychological and emotional functioning: well adjusted (46.2%), moderately adjusted (44.3%), and struggling (9.5%). Discriminant function analysis confirmed the groupings and revealed that family functioning was among the most influential factors explaining adjustment differences. Multivariate analyses of variance (MANOVAs) further showed that adolescents from each of the three adjustment profiles reported significantly different levels of family social support, parental involvement, and perceived neighborhood safety. Overall, the results confirm heterogeneity of adolescent adaptation in the aftermath of family violence and provide insights into family and neighborhood factors that account for variability in adolescents’ reactions to violence. Implications for future research and practical interventions are discussed. PMID:27106255

This study examines differences in psychological adjustment in a sample of rural adolescents who have been exposed to family violence. Self-report questionnaires were administered to 580 adolescents and their primary caregivers. The results revealed that over two thirds of the study participants (68.8%) had been exposed to violence in their families. As hypothesized, cluster analysis identified several profiles among adolescents, distinguished by their psychological and emotional functioning: well adjusted (46.2%), moderately adjusted (44.3%), and struggling (9.5%). Discriminant function analysis confirmed the groupings and revealed that family functioning was among the most influential factors explaining adjustment differences. Multivariate analyses of variance (MANOVAs) further showed that adolescents from each of the three adjustment profiles reported significantly different levels of family social support, parental involvement, and perceived neighborhood safety. Overall, the results confirm heterogeneity of adolescent adaptation in the aftermath of family violence and provide insights into family and neighborhood factors that account for variability in adolescents' reactions to violence. Implications for future research and practical interventions are discussed. © The Author(s) 2016.

To compare intensiveness of use of child preventive health services (CPHS) between cross-cultural immigrant families and native-born families in Taiwan and to explore factors associated with differences in intensiveness of CPHS use. Cross-cultural immigrant families were defined as families where the mother was an immigrant from another southeast Asian country. In native-born families, both parents were Taiwanese-born. Data were collected from 318 immigrant mothers and 340 native-born mothers of children aged 7 years or younger in a cross-sectional survey in central Taiwan. A social determinants framework of health inequities was constructed, and ordinal logistic regression models were used to examine the effect of four domains of intermediary determinants on the relationship between family type and underuse of CPHS: CPHS-related factors, medical-related factors, maternal acculturation factors, and sociodemographic/socioeconomic characteristics. Cross-cultural immigrant families were less likely to intensively use CPHS than native-born families. This difference appeared to be mediated by the greater likelihood of having an older child or a lower educated father in cross-cultural families. Findings of this study highlight the importance of promoting health behaviors and combating health inequities and social inequalities for cross-cultural immigrant families in Taiwan from a sociodemographic/socioeconomic and political context.

Sudden cardiac death of the young (SCDY) is a devastating event for families and communities. Family history is a significant risk factor for this potentially preventable cause of death, however a complete and detailed family history is not commonly obtained during routine health maintenance visits. To estimate the proportion of adults with a family history of SCDY, the Michigan Department of Health and Human Services (MDHHS) Genomics Program included two questions within the 2007 Michigan Behavioral Risk Factor Survey (MiBRFS). Prevalence estimates and 95% confidence intervals were calculated. Among adults in Michigan, 6.3% reported a family history of SCDY, with a greater prevalence among blacks, those with lower household income, and those with less education. Among those reporting a family history of SCDY, 42.3% had at least one first-degree relative and 26.2% had multiple affected family members. This is the first study to demonstrate the prevalence of family history of SCDY while also highlighting key sociodemographic characteristics associated with increased prevalence. These findings should guide evidence-based interventions to reach those at greatest risk. PMID:27417815

The global prevalence of obesity has reached alarming proportions. In Cuba, the rise in numbers of children who are overweight or obese, especially preschoolers and adolescents, is similar to that observed in developed countries. Beyond the physical risk factors, there is evidence that obesity has negative psychological, social, academic and economic effects. Describe the psychological, behavioral and familial factors present in a group of obese children and adolescents in Cuba. This is a qualitative cross-sectional study of 202 obese children and adolescents aged 3-18 years, with an average age of 9.9 years, seen at the Medical-Surgical Research Center (Havana) psychology service from January 2009 through December 2012. Techniques included interviews of patients and parents, projective drawings and the Rotter Incomplete Sentence Blank. Unhealthy eating habits were reported in 96% of obese children and adolescents, and sedentary lifestyles in 88.1%. Emotional state was affected in 80.2%, and in 72.3% there were family attitudes with potential to produce psychological disturbances in children. Psychological, behavioral, and familial factors known to foster development and perpetuation of obesity were observed in the majority of cases. This is a first diagnostic stage that will aid in design and implementation of a psychological intervention program for obese and overweight children and their families.

To investigate the relationship between a child's weight and a broad range of family and maternal factors. Cross-sectional data from a population-based prospective study, collected between January 2004 and December 2005, for 329 children aged 6-13 years (192 healthy weight, 97 overweight and 40 obese) and their mothers (n=265) recruited from a paediatric hospital endocrinology department and eight randomly selected primary schools in Perth, Western Australia. Height, weight and body mass index (BMI) of children and mothers; demographic information; maternal depression, anxiety, stress and self-esteem; general family functioning; parenting style; and negative life events. In a multilevel model, maternal BMI and family structure (single-parent v two-parent families) were the only significant predictors of child BMI z scores. Childhood obesity is not associated with adverse maternal or family characteristics such as maternal depression, negative life events, poor general family functioning or ineffective parenting style. However, having an overweight mother and a single-parent (single-mother) family increases the likelihood of a child being overweight or obese.

There has been increasing awareness of the need for research and theory to take into account the intersection of individual characteristics and environmental contexts when examining predictors of child outcomes. The present longitudinal, multi-informant study examined the cumulative and interacting contributions of child characteristics (language skills, inattention/hyperactivity, and aggression) and preschool and family contextual factors in predicting kindergarten social skills in 389 low-income preschool children. Child characteristics and classroom factors, but not family factors, predicted teacher-rated kindergarten social skills, while child characteristics alone predicted change in teacher-rated social skills from preschool to kindergarten. Child characteristics and family factors, but not classroom factors, predicted parent-rated kindergarten social skills. Family factors alone predicted change in parent-rated social skills from preschool to kindergarten. Individual child characteristics did not interact with family or classroom factors in predicting parent- or teacher-rated social skills, and support was therefore found for an incremental, rather than an interactive, predictive model of social skills. The findings underscore the importance of assessing outcomes in more than one context, and of considering the impact of both individual and environmental contextual factors on children's developing social skills when designing targeted intervention programs to prepare children for kindergarten.

To examine the relationship of family, friend, and media factors on weight-control group membership at 15 years separately and in a combined model. Subjects included 166 15 year girls. Latent class analysis identified four patterns of weight-control behaviors: non-dieters, lifestyle, dieters, and extreme dieters. Family (family functioning, priority of the family meals, maternal/paternal weight-teasing, and mother's/father's dieting), friend (weight-teasing and dieting), and media variables (media sensitivity and weekly TV time) were included as predictors of weight-control group membership. Family functioning and priority of family meals predicted membership in the Extreme Dieters group, and maternal weight-teasing predicted membership in both dieters and extreme dieters. Friend's dieting and weight-teasing predicted membership in both dieters and extreme dieters. Media sensitivity was significantly associated with membership in lifestyle, dieters, and extreme dieters. In a combined influence model with family, friend, and media factors included, the following remained significantly associated with weight-control group membership: family functioning, friends' dieting, and media sensitivity. Family, friends, and the media are three sources of sociocultural influence, which play a role in adolescent girls' use of patterns of weight-control behaviors; family functioning was a protective factor, whereas friend's dieting and media sensitivity were risk factors. These findings emphasize the need for multidimensional interventions, addressing risk factors for dieting and use of unhealthy weight-control behaviors at the family, peer, and community (e.g., media) levels.

The genetic basis of Alzheimer's disease (AD) is complex and heterogeneous. Over 200 highly penetrant pathogenic variants in the genes APP, PSEN1 and PSEN2 cause a subset of early-onset familial Alzheimer's disease (EOFAD). On the other hand, susceptibility to late-onset forms of AD (LOAD) is indisputably associated to the ε4 allele in the gene APOE, and more recently to variants in more than two-dozen additional genes identified in the large-scale genome-wide association studies (GWAS) and meta-analyses reports. Taken together however, although the heritability in AD is estimated to be as high as 80%, a large proportion of the underlying genetic factors still remain to be elucidated. In this study we performed a systematic family-based genome-wide association and meta-analysis on close to 15 million imputed variants from three large collections of AD families (~3,500 subjects from 1,070 families). Using a multivariate phenotype combining affection status and onset age, meta-analysis of the association results revealed three single nucleotide polymorphisms (SNPs) that achieved genome-wide significance for association with AD risk: rs7609954 in the gene PTPRG (P-value = 3.98·10−08), rs1347297 in the gene OSBPL6 (P-value = 4.53·10−08), and rs1513625 near PDCL3 (P-value = 4.28·10−08). In addition, rs72953347 in OSBPL6 (P-value = 6.36·10−07) and two SNPs in the gene CDKAL1 showed marginally significant association with LOAD (rs10456232, P-value: 4.76·10−07; rs62400067, P-value: 3.54·10−07). In summary, family-based GWAS meta-analysis of imputed SNPs revealed novel genomic variants in (or near) PTPRG, OSBPL6, and PDCL3 that influence risk for AD with genome-wide significance.

This multi-centre cross-sectional study explored associations between prevalence of depression and exposure to intimate partner violence (IPV) at any time in patients' adult life in 471 participants of a previous IPV study. In 2016, 174 interviews were performed, using the Short Form Domestic Violence Exposure Questionnaire, the Zung Scale and questions about behavioural patterns of exposure to IPV. Family doctors reviewed patients' medical charts for period from 2012 to 2016, using the Domestic Violence Exposure Medical Chart Check List, for conditions which persisted for at least three years. Depression was found to be associated with any exposure to IPV in adult life and was more likely to affect women. In multivariable logistic regression modelling, factors associated with self-rated depression were identified (p < 0.05). Exposure to emotional and physical violence was identified as a risk factor in the first model, explaining 23% of the variance. The second model explained 66% of the variance; past divorce, dysfunctional family relationships and a history of incapacity to work increased the likelihood of depression in patients. Family doctors should consider IPV exposure when detecting depression, since lifetime IPV exposure was found to be 40.4% and 36.9% of depressed revealed it.

Family history of rheumatoid arthritis (RA) is one of the strongest risk factors for developing RA, and information on family history is, therefore, routinely collected in clinical practice. However, as more genetic and environmental risk factors shared by relatives are identified, the importance of family history may diminish. The aim of this study was to determine how much of the familial risk of RA can be explained by established genetic and nongenetic risk factors. History of RA among first-degree relatives of individuals in the Epidemiological Investigation of Rheumatoid Arthritis case-control study was assessed through linkage to the Swedish Multigeneration Register and the Swedish Patient Register. We used logistic regression models to investigate the decrease in familial risk after successive adjustment for combinations of nongenetic risk factors (smoking, alcohol intake, parity, silica exposure, body mass index, fatty fish consumption, and education), and genetic risk factors (shared epitope [SE] and 76 single-nucleotide polymorphisms [SNPs]). Established nongenetic risk factors did not explain familial risk of either seropositive or seronegative RA to any significant degree. Genetic risk factors accounted for a limited proportion of the familial risk of seropositive RA (unadjusted odds ratio [OR] 4.10, SE-adjusted OR 3.72, SNP-adjusted OR 3.46, and SE and SNP-adjusted OR 3.35). Established risk factors only provided an explanation for familial risk of RA in minor part, suggesting that many (familial) risk factors remain to be identified, in particular for seronegative RA. Family history of RA therefore remains an important clinical risk factor for RA, the value of which has not yet been superseded by other information. There is thus a need for further etiologic studies of both seropositive and seronegative RA. Copyright © 2015 by the American College of Rheumatology.

Adaptation and resiliency in Swedish families.

A longitudinal research project began in 1993 of Norwegian, Swedish and American mothers' perception of her family's dynamics and adaptation during childbearing and childrearing. Results indicated that Swedish mothers adapted better than other mothers. In 2003, a mixed design study was conducted with original Swedish mothers that aimed to describe the experience of motherhood, the meaning mothers attached to events in their lives that made adaptation necessary, and ways in which they achieved adaptation. Fourteen mothers completed quantitative instruments and 13 of those mothers were interviewed. Audiotaped interviews were transcribed and analysed for themes using a protocol based on a model of family resiliency. Quantitative findings revealed statistically significant findings in areas of children, mother's work outside the home and families in which a major illness had occurred. Qualitative findings revealed that protective factors far outweighed vulnerability and risk factors. Mothers' satisfaction with life manifested itself in love of home, contentment with employment, fulfillment from an active and healthy life and support from a society that provides a wide range of social benefits for the family. Vulnerability occurred primarily when mothers were tired, lacked personal time or someone in the family was experiencing a serious illness. Results of this study enhance the scholarly scientific knowledge about the uniqueness of Swedish mothers, and increased understanding of family dynamics and adaptation. Many of the findings relate in some way to overall social benefits and supports available for families.

Family Obligation Values and Family Assistance Behaviors: Protective and Risk Factors for Mexican-American Adolescents’ Substance Use

PubMed Central

2014-01-01

Adolescent substance use is one of today’s most important social concerns, with Latino youth exhibiting the highest overall rates of substance use. Recognizing the particular importance of family connection and support for families from Mexican backgrounds, the current study seeks to examine how family obligation values and family assistance behaviors may be a source of protection or risk for substance use among Mexican-American adolescents. Three hundred and eighty-five adolescents (51% female) from Mexican backgrounds completed a questionnaire and daily diary for 14 consecutive days. Results suggest that family obligation values are protective, relating to lower substance use, due, in part, to the links with less association with deviant peers and increased adolescent disclosure. In contrast, family assistance behaviors are a source of risk within high parent-child conflict homes, relating to higher levels of substance use. These findings suggest that cultural values are protective against substance use, but the translation of these values into behaviors can be a risk factor depending upon the relational context of the family.

MADS-box transcription factors play significant roles in plant developmental processes such as floral organ conformation, flowering time, and fruit development. Pear (Pyrus), as the third-most crucial temperate fruit crop, has been fully sequenced. However, there is limited information about the MADS family and its functional divergence in pear. In this study, a total of 95 MADS-box genes were identified in the pear genome, and classified into two types by phylogenetic analysis. Type I MADS-box genes were divided into three subfamilies and type II genes into 14 subfamilies. Synteny analysis suggested that whole-genome duplications have played key roles in the expansion of the MADS family, followed by rearrangement events. Purifying selection was the primary force driving MADS-box gene evolution in pear, and one gene pairs presented three codon sites under positive selection. Full-scale expression information for PbrMADS genes in vegetative and reproductive organs was provided and proved by transcriptional and reverse transcription PCR analysis. Furthermore, the PbrMADS11(12) gene, together with partners PbMYB10 and PbbHLH3 was confirmed to activate the promoters of the structural genes in anthocyanin pathway of red pear through dual luciferase assay. In addition, the PbrMADS11 and PbrMADS12 were deduced involving in the regulation of anthocyanin synthesis response to light and temperature changes. These results provide a solid foundation for future functional analysis of PbrMADS genes in different biological processes, especially of pigmentation in pear. PMID:28924499

This cross-sectional study explores the influence of multiple familial factors on children's weight status and the interaction between parenting stress and unfavourable family characteristics. A total of 197 families with children between 6 and 14 years participated in this study. Of this group, 97 families had a child with normal weight and 100 families had a child with overweight. Parents reported on seven family factors (maternal BMI, number of children, family structure, socioeconomic position, life events, parental psychopathology and parenting stress). Families with overweight children experience more parenting stress. A regression analysis revealed that familial factors explain 27% in the variance in child's weight status. The hypothesis that a combination of familial factors will be more able to explain child's adiposity could not be confirmed. Familial factors have moderate ability to predict children's weight status. There is a need to identify other familial mechanisms taking into account developmental and temporal evolutions over the past decade. 2009 John Wiley & Sons, Ltd and Eating Disorders Association

A compendium of transcription factor and Transcriptionally active protein coding gene families in cowpea (Vigna unguiculata L.).

Cowpea (Vigna unguiculata (L.) Walp.) is the most important food and forage legume in the semi-arid tropics of sub-Saharan Africa where approximately 80% of worldwide production takes place primarily on low-input, subsistence farm sites. Among the major goals of cowpea breeding and improvement programs are the rapid manipulation of agronomic traits for seed size and quality and improved resistance to abiotic and biotic stresses to enhance productivity. Knowing the suite of transcription factors (TFs) and transcriptionally active proteins (TAPs) that control various critical plant cellular processes would contribute tremendously to these improvement aims. We used a computational approach that employed three different predictive pipelines to data mine the cowpea genome and identified over 4400 genes representing 136 different TF and TAP families. We compare the information content of cowpea to two evolutionarily close species common bean (Phaseolus vulgaris), and soybean (Glycine max) to gauge the relative informational content. Our data indicate that correcting for genome size cowpea has fewer TF and TAP genes than common bean (4408 / 5291) and soybean (4408/ 11,065). Members of the GROWTH-REGULATING FACTOR (GRF) and Auxin/indole-3-acetic acid (Aux/IAA) gene families appear to be over-represented in the genome relative to common bean and soybean, whereas members of the MADS (Minichromosome maintenance deficient 1 (MCM1), AGAMOUS, DEFICIENS, and serum response factor (SRF)) and C2C2-YABBY appear to be under-represented. Analysis of the AP2-EREBP APETALA2-Ethylene Responsive Element Binding Protein (AP2-EREBP), NAC (NAM (no apical meristem), ATAF1, 2 (Arabidopsis transcription activation factor), CUC (cup-shaped cotyledon)), and WRKY families, known to be important in defense signaling, revealed changes and phylogenetic rearrangements relative to common bean and soybean that suggest these groups may have evolved different functions.

The current study aimed to describe the prevalence of children of incarcerated parents (COIP) in a sample of homeless/highly mobile children, examine the relationship between parental incarceration and other risk factors, and investigate the effect of parental incarceration on child academic and mental health outcomes. The authors compared COIP (n = 45) to children whose parents were never incarcerated (n = 93) within a sample of 138, 4- to 7-year-old ethnically diverse children residing in emergency homeless shelters. Children's caregivers provided information about children's history of parental incarceration and other family experiences. Children's teachers reported academic and mental health outcomes in the subsequent school year. Compared to children with no history of parental incarceration, COIP experienced more negative life events. Regression models revealed that a history of parental incarceration was a significant predictor of teacher-reported internalizing problems. These results have implications for the identification and treatment of the highest risk homeless/highly mobile children. PMID:26478648

Evaluate the factor structure of youth and maternal involvement ratings on the Inflammatory Bowel Disease Family Responsibility Questionnaire, a measure of family allocation of condition management responsibilities in pediatric inflammatory bowel disease. Participants included 251 youth aged 11-18 years with inflammatory bowel disease and their mothers. Item-level descriptive analyses, subscale internal consistency estimates, and confirmatory factor analyses of youth and maternal involvement were conducted using a dyadic data-analytic approach. Results supported the validity of 4 conceptually derived subscales including general health maintenance, social aspects, condition management tasks, and nutrition domains. Additionally, results indicated adequate support for the factor structure of a 21-item youth involvement measure and strong support for a 16-item maternal involvement measure. Additional empirical support for the validity of the Inflammatory Bowel Disease Family Responsibility Questionnaire was provided. Future research to replicate current findings and to examine the measure's clinical utility is warranted.

Analyses of the functions of TEOSINTE-LIKE1, CYCLOIDEA, and PROLIFERATING CELL FACTOR1 (TCP) transcription factors have been hampered by functional redundancy between its individual members. In general, putative functionally redundant genes are predicted based on sequence similarity and confirmed by genetic analysis. In the TCP family, however, identification is impeded by relatively low overall sequence similarity. In a search for functionally redundant TCP pairs that control Arabidopsis leaf development, this work performed an integrative bioinformatics analysis, combining protein sequence similarities, gene expression data, and results of pair-wise protein-protein interaction studies for the 24 members of the Arabidopsis TCP transcription factor family. For this, the work completed any lacking gene expression and protein-protein interaction data experimentally and then performed a comprehensive prediction of potential functional redundant TCP pairs. Subsequently, redundant functions could be confirmed for selected predicted TCP pairs by genetic and molecular analyses. It is demonstrated that the previously uncharacterized class I TCP19 gene plays a role in the control of leaf senescence in a redundant fashion with TCP20. Altogether, this work shows the power of combining classical genetic and molecular approaches with bioinformatics predictions to unravel functional redundancies in the TCP transcription factor family.

Critical gaps remain in our understanding of the obesigenic family environment. This study examines parent and family characteristics among obese youth presenting for treatment in a clinic setting. Families of 78 obese youth (BMI z-score = 2.4; age, 8 to 16 years; 59% girls; 49% African-American) were compared with 71 non-overweight (BMI z-score = -0.02) demographically matched comparisons. Parents completed measures assessing family demographics, psychological distress (Symptom Checklist 90-Revised), and family functioning both broadly (Family Environment Scale: Conflicted, Support, Control) and at mealtimes (About Your Child's Eating-Revised: Mealtime Challenges, Positive Mealtime Interaction). Height and weight were obtained from all participants. Compared with mothers and fathers of non-overweight youth, parents of obese youth had significantly higher BMIs (p < 0.001). Mothers of obese youth reported significantly greater psychological distress (p < 0.01), higher family conflict (p < 0.05), and more mealtime challenges (p < 0.01). Less positive family mealtime interactions were reported by both mothers (p < 0.01) and fathers (p < 0.05) of obese youth. These group differences did not vary by child sex or race. Logistic regression analyses indicated that maternal distress and mealtime challenges discriminated between obese and non-overweight youth after controlling for maternal BMI. Family conflict was explained, in part, by maternal distress. Obese youth who present for treatment in a clinic setting are characterized by psychosocial factors at the parent and family level that differ from non-overweight youth. These data are critical because they identify factors that may be serving as barriers to a family's or youth's ability to implement healthy lifestyle behaviors but that are potentially modifiable.

Factors influencing bereaved families' decisions about organ donation: an integrative literature review.

This article reports on the process and outcomes of a systematic integrative literature review, designed to enhance understanding of the factors influencing bereaved families' decisions to agree or decline the donation of their deceased relative's organs for transplantation. Research originating from eight Western countries (N = 20 studies) provided an international perspective to the review. Thematic analysis and synthesis of textual data culminated in the development of three global themes (past, present, and future) that captured the temporal dimensions of family decision making. The review findings provide valuable insight into ways of increasing the rate of consent to organ donation through the development family-centered care interventions that reflect the needs of the bereaved. Further research to explore the pathway of donation after circulatory death and the experiences of bereaved families who decline organ donation is essential to providing a more complete understanding of the factors affecting donation decisions.

The purpose of this study was to explore the factor structure of the Work-Family Balance Scale (WFBS) and examine its reliability and validity in use in the urban Chinese population. The scale was validated using a sample of 605 urban Chinese residents from 7 cities. Exploratory factor analysis identified two factors: work-family conflict and work-family enrichment. The WFBS showed adequate reliability and concurrent validity. The WFBS is a reliable and valid instrument to measure work-family balance for Chinese working parents. However, further examination of the scale is needed.

The activity of specific signaling and transcription factors determines the cell fate in normal development and in tumor transformation. The transcriptional profiles of gene-components of different branches of TGFbeta family signaling pathways were studied in experimental models of initial stages of three-dimensional in vitro differentiation of embryonic stem cells, embryonic germ cells and teratocarcinoma cells and in teratomas and teratocarcinomas developed after their transplantation into immunodeficient Nude mice. Gene profile analysis of studied cell systems have revealed that expression patterns of ActivinA, Nodal, Lefty1, Lefty2, TGF TGFbeta1, BMP4, and GDF were identical in pluripotent stem cells whereas the mRNAs of all examined genes with the exception of Inhibin betaA/ActivinA were detected in the teratocarcinoma cells. These results indicate that differential activity of signaling pathways of the TGFbeta family factors regulates pluripotent state maintenance and pluripotent stem cell differentiation into the progenitors of three germ layers and extraembryonic structures and that normal expression pattern of TGFbeta family factors is rearranged in embryonic teratocarcinoma cells during tumor growth in vitro and in vivo.

Dental fear and anxiety (DFA) is a major issue affecting children's oral health and clinical management. This study investigates the association between children's DFA and family related factors, including parents' DFA, parenting styles, family structure (nuclear or single-parent family), and presence of siblings. A total of 405 children (9-13 years old) and their parents were recruited from 3 elementary schools in Hong Kong. Child's demographic and family-related information was collected through a questionnaire. Parents' and child's DFA were measured by using the Corah Dental Anxiety Scale (CDAS) and Children Fear Survey Schedule-Dental Subscale (CFSS-DS), respectively. Parenting styles were gauged by using the Parent Authority Questionnaire (PAQ). DFA was reported by 33.1% of children. The mean (SD) CFSS-DS score was 29.1 (11.0). Children with siblings tended to report DFA (37.0% vs. 24.1%; p = 0.034) and had a higher CFSS-DS score (29.9 vs. 27.4; p = 0.025) as compared with their counterpart. Children from single-parent families had lower CFSS-DS score as compared with children from nuclear families (β = - 9.177; p = 0.029). Subgroup analysis showed a higher CFSS-DS score among boys with siblings (β = 7.130; p = 0.010) as compared with their counterpart; girls' from single-parent families had a lower CFSS-DS score (β = - 13.933; p = 0.015) as compared with girls from nuclear families. Children's DFA was not associated with parents' DFA or parenting styles (p > 0.05). Family structure (nuclear or single-parent family) and presence of siblings are significant determinants for children's DFA. Parental DFA and parenting style do not affect children's DFA significantly.

Transcription factors (TFs) play essential roles in the regulatory networks controlling many developmental processes in plants. Members of the basic leucine (Leu) zipper (bZIP) TF family, which is unique to eukaryotes, are involved in regulating diverse processes, including flower and vascular development, seed maturation, stress signaling, and defense responses to pathogens. The bZIP proteins have a characteristic bZIP domain composed of a DNA-binding basic region and a Leu zipper dimerization region. In this study, we identified 112 apple (Malus domestica Borkh) bZIP TF-encoding genes, termed MdbZIP genes. Synteny analysis indicated that segmental and tandem duplication events, as well as whole genome duplication, have contributed to the expansion of the apple bZIP family. The family could be divided into 11 groups based on structural features of the encoded proteins, as well as on the phylogenetic relationship of the apple bZIP proteins to those of the model plant Arabidopsis thaliana (AtbZIP genes). Synteny analysis revealed that several paired MdbZIP genes and AtbZIP gene homologs were located in syntenic genomic regions. Furthermore, expression analyses of group A MdbZIP genes showed distinct expression levels in 10 different organs. Moreover, changes in these expression profiles in response to abiotic stress conditions and various hormone treatments identified MdbZIP genes that were responsive to high salinity and drought, as well as to different phytohormones.

Midaortic syndrome (MAS) is a rare cause of severe childhood hypertension characterized by narrowing of the abdominal aorta in children and is associated with extensive vascular disease. It may occur as part of a genetic syndrome, such as neurofibromatosis, or as consequence of a pathological inflammatory disease. However, most cases are considered idiopathic. We hypothesized that in a high percentage of these patients, a monogenic cause of disease may be detected by evaluating whole exome sequencing data for mutations in 1 of 38 candidate genes previously described to cause vasculopathy. We studied a cohort of 36 individuals from 35 different families with MAS by exome sequencing. In 15 of 35 families (42.9%), we detected likely causal dominant mutations. In 15 of 35 (42.9%) families with MAS, whole exome sequencing revealed a mutation in one of the genes previously associated with vascular disease ( NF1 , JAG1 , ELN , GATA6 , and RNF213 ). Ten of the 15 mutations have not previously been reported. This is the first report of ELN , RNF213 , or GATA6 mutations in individuals with MAS. Mutations were detected in NF1 (6/15 families), JAG1 (4/15 families), ELN (3/15 families), and one family each for GATA6 and RNF213 Eight individuals had syndromic disease and 7 individuals had isolated MAS. Whole exome sequencing can provide conclusive molecular genetic diagnosis in a high fraction of individuals with syndromic or isolated MAS. Establishing an etiologic diagnosis may reveal genotype/phenotype correlations for MAS in the future and should, therefore, be performed routinely in MAS. © 2018 American Heart Association, Inc.

2010-01-01

A phylogenetic analysis of the basic helix-loop-helix (bHLH) gene superfamily was performed using seven different species (human, mouse, rat, worm, fly, yeast, and plant Arabidopsis) and involving over 600 bHLH genes [1]. All bHLH genes were identified in the genomes of the various species, including expressed sequence tags, and the entire coding sequence was used in the analysis. Nearly 15% of the gene family has been updated or added since the original publication. A super-tree involving six clades and all structural relationships was established and is now presented for four of the species. The wealth of functional data available for members of the bHLH gene superfamily provides us with the opportunity to use this exhaustive phylogenetic tree to predict potential functions of uncharacterized members of the family. This phylogenetic and genomic analysis of the bHLH gene family has revealed unique elements of the evolution and functional relationships of the different genes in the bHLH gene family.

2010-01-01

The aim of this study was to analyze the protective factors that prevent drug use in the families of children who attend Community Homes of Family Well-being in a small Colombian locality. This was a quantitative, descriptive, transversal study, with 256 families constituting the sample. Data were collected through a self-applied questionnaire throughout March and April 2007. Protective factors found included demonstrations of affection toward the children, playing with them and talking to them about things they like, open communication, decision making as a couple, flexibility of the nursing process, and establishment of rules. However, some risk factors were also found, such as consumption of legal drugs such as cigarettes and alcohol, and in a low percentage, consumption of illicit drugs. A high percentage of families consider that drug use must be prevented in the first years of life, by the parents. The protective factors found require reinforcement as they are not very strong, and the risk factors must be controlled to turn them into protective factors.

To explore the confounding effects of early family factors shared by siblings and cardiovascular risk factors in midlife on the educational differences in mortality from cardiovascular disease (CVD). Data from national and regional health surveys in Norway (1974-2003) were linked with data from the Norwegian Family Based Life Course Study, the National Educational Registry and the Cause of Death Registry. The study population consisted of participants with at least one full sibling among the health survey participants ( n=271,310). Data were available on CVD risk factors, including weight, height, blood pressure, total cholesterol and smoking. The hazards ratio (HR) of CVD mortality was 3.44 (95% confidence interval (CI) 2.98-3.96) in the lowest educational group relative to the highest. The HRs were little altered in the within-sibship analyses. Adjusted for risk factors, the HR for CVD mortality in the cohort analyses was 2.05 (CI 1.77-2.37) in the lowest educational group relative to the highest. The respective HR in the within-sibship analyses was 2.46 (CI 1.48-2.24). Using a sibling design, we did not find that the association between education and CVD mortality was confounded by early life factors shared by siblings, but it was explained to a large extent by CVD risk factors. These results suggest that reducing levels of CVD risk factors could have the greatest effect on mortality in less well-educated people.

OBJECTIVE: To examine factors that influence family physicians' decisions to practise palliative care. DESIGN: Qualitative method of in-depth interviews. SETTING: Southwestern Ontario. PARTICIPANTS: Family physicians who practise palliative care on a full-time basis, who practise on a part-time basis, or who have retired from active involvement in palliative care. METHOD: Eleven in-depth interviews were conducted to explore factors that influence family physicians' decisions to practise palliative care and factors that sustain their interest in palliative care. All interviews were audiotaped and transcribed verbatim. The analysis strategy used a phenomenological approach and occurred concurrently rather than sequentially. All interview transcriptions were read independently by the researchers, who then compared and combined their analyses. Final analysis involved examining all interviews collectively, thus permitting relationships between and among central themes to emerge. MAIN OUTCOME FINDINGS: The overriding theme was a common philosophy of palliative care focusing on acceptance of death, whole person care, compassion, communication, and teamwork. Participants' philosophies were shaped by their education and by professional and personal experiences. In addition, participants articulated personal and systemic factors currently affecting their practice of palliative care. CONCLUSIONS: Participants observed that primary care physicians should be responsible for their patients' palliative care within the context of interdisciplinary teams. For medical students to be knowledgeable and sensitive to the needs of dying patients, palliative care should be given higher priority in the curriculum. Finally, participants argued compellingly for transferring the philosophy of palliative care to the overall practice of medicine. PMID:9612588

2013-08-01

NAC [no apical meristem (NAM), Arabidopsis thaliana transcription activation factor [ATAF1/2] and cup-shaped cotyledon (CUC2)] proteins belong to one of the largest plant-specific transcription factor (TF) families and play important roles in plant development processes, response to biotic and abiotic cues and hormone signalling. Our genome-wide analysis identified 110 StNAC genes in potato encoding for 136 proteins, including 14 membrane-bound TFs. The physical map positions of StNAC genes on 12 potato chromosomes were non-random, and 40 genes were found to be distributed in 16 clusters. The StNAC proteins were phylogenetically clustered into 12 subgroups. Phylogenetic analysis of StNACs along with their Arabidopsis and rice counterparts divided these proteins into 18 subgroups. Our comparative analysis has also identified 36 putative TNAC proteins, which appear to be restricted to Solanaceae family. In silico expression analysis, using Illumina RNA-seq transcriptome data, revealed tissue-specific, biotic, abiotic stress and hormone-responsive expression profile of StNAC genes. Several StNAC genes, including StNAC072 and StNAC101that are orthologs of known stress-responsive Arabidopsis RESPONSIVE TO DEHYDRATION 26 (RD26) were identified as highly abiotic stress responsive. Quantitative real-time polymerase chain reaction analysis largely corroborated the expression profile of StNAC genes as revealed by the RNA-seq data. Taken together, this analysis indicates towards putative functions of several StNAC TFs, which will provide blue-print for their functional characterization and utilization in potato improvement.

Background A chicken egg contains several biotin-binding proteins (BBPs), whose complete DNA and amino acid sequences are not known. In order to identify and characterise these genes and proteins we studied chicken cDNAs and genes available in the NCBI database and chicken genome database using the reported N-terminal amino acid sequences of chicken egg-yolk BBPs as search strings. Results Two separate hits showing significant homology for these N-terminal sequences were discovered. For one of these hits, the chromosomal location in the immediate proximity of the avidin gene family was found. Both of these hits encode proteins having high sequence similarity with avidin suggesting that chicken BBPs are paralogous to avidin family. In particular, almost all residues corresponding to biotin binding in avidin are conserved in these putative BBP proteins. One of the found DNA sequences, however, seems to encode a carboxy-terminal extension not present in avidin. Conclusion We describe here the predicted properties of the putative BBP genes and proteins. Our present observations link BBP genes together with avidin gene family and shed more light on the genetic arrangement and variability of this family. In addition, comparative modelling revealed the potential structural elements important for the functional and structural properties of the putative BBP proteins. PMID:15777476

Although nitrate represents an important nitrogen (N) source for maize, a major crop of dryland areas, the molecular mechanisms of nitrate uptake and assimilation remain poorly understood. Here, we identified nine maize NIN-like protein (ZmNLP) genes and analyzed the function of one member, ZmNLP3.1, in nitrate nutrition and signaling. The NLP family genes were clustered into three clades in a phylogenic tree. Comparative genomic analysis showed that most ZmNLP genes had collinear relationships to the corresponding NLPs in rice, and that the expansion of the ZmNLP family resulted from segmental duplications in the maize genome. Quantitative PCR analysis revealed the expression of ZmNLP2.1, ZmNLP2.2, ZmNLP3.1, ZmNLP3.2, ZmNLP3.3, and ZmNLP3.4 was induced by nitrate in maize roots. The function of ZmNLP3.1 was investigated by overexpressing it in the Arabidopsis nlp7-1 mutant, which is defective in the AtNLP7 gene for nitrate signaling and assimilation. Ectopic expression of ZmNLP3.1 restored the N-deficient phenotypes of nlp7-1 under nitrate-replete conditions in terms of shoot biomass, root morphology and nitrate assimilation. Furthermore, the nitrate induction of NRT2.1, NIA1, and NiR1 gene expression was recovered in the 35S::ZmNLP3.1/nlp7-1 transgenic lines, indicating that ZmNLP3.1 plays essential roles in nitrate signaling. Taken together, these results suggest that ZmNLP3.1 plays an essential role in regulating nitrate signaling and assimilation processes, and represents a valuable candidate for developing transgenic maize cultivars with high N-use efficiency.

Tuberculosis, caused by Mycobacterium tuberculosis, remains a leading infectious disease taking one human life every 15 s globally. The two well-characterized strains H37Rv and H37Ra, derived from the same parental strain M. tuberculosis H37, show dramatically different pathogenic phenotypes. PE/PPE gene family, comprising of 176 open reading frames and present exclusively in genus Mycobacterium, accounts for ∼10% of the M. tuberculosis genome. Our comprehensive in silico analyses of PE/PPE family of H37Ra and virulent H37Rv strains revealed genetic differences between these strains in terms of several single nucleotide variations and InDels and these manifested in changes in physico-chemical properties, phosphorylation sites, and protein: protein interacting domains of the corresponding proteomes. Similar comparisons using the 13 sigma factor genes, 36 members of the mammalian cell entry family, 13 mycobacterial membrane protein large family members and 11 two-component signal transduction systems along with 5 orphaned response regulators and 2 orphaned sensor kinases failed to reveal very significant difference between H37Rv and H37Ra, reinforcing the importance of PE/PPE genes. Many of these changes between H37Rv and H37Ra can be correlated to differences in pathogenesis and virulence of the two strains. PMID:22618876

Cnidarians are probably the oldest group of animals to be venomous, yet our current picture of cnidarian venom evolution is highly imbalanced due to limited taxon sampling. High-throughput tandem mass spectrometry was used to determine venom composition of the scyphozoan Chrysaora lactea and two cubozoans Tamoya haplonema and Chiropsalmus quadrumanus. Protein recruitment patterns were then compared against 5 other cnidarian venom proteomes taken from the literature. A total of 28 putative toxin protein families were identified, many for the first time in Cnidaria. Character mapping analysis revealed that 17 toxin protein families with predominantly cytolytic biological activities were likely recruited into the cnidarian venom proteome before the lineage split between Anthozoa and Medusozoa. Thereafter, venoms of Medusozoa and Anthozoa differed during subsequent divergence of cnidarian classes. Recruitment and loss of toxin protein families did not correlate with accepted phylogenetic patterns of Cnidaria. Selective pressures that drive toxin diversification independent of taxonomic positioning have yet to be identified in Cnidaria and now warrant experimental consideration.

From a social disorganization standpoint, neighborhood residential instability potentially brings negative consequences to parent-child relationship qualities, but family social support and racial/ethnic identity may modify this association. Using data (n = 3,116) from the Project on Human Development in Chicago Neighborhoods, this study examines associations between neighborhood residential instability and parent-child warmth and conflict, whether family social support moderates associations between residential instability and parent-child relationships, and variation by race/ethnicity. Multilevel models reveal that residential instability undermines parent-child relationship qualities, particularly for non-White individuals. Family support is a protective factor for families in less stable neighborhoods, and specifically buffers the association between neighborhood residential instability and reduced parent-child warmth. Among Hispanics, family support mitigates the association between residential instability and heightened parent-child conflict. Findings highlight residential instability as a detriment to parent-child relationships; families in unstable neighborhoods may benefit from family social support.

Bijttebier, Patricia; Goethals, Eveline

2006-06-01

In the present study, the relationships among parental drinking, family environment, and child adjustment is investigated in a community sample of 207 10-14-year-olds. Multiple aspects of perceived family environment (e.g., cohesion, organization, conflict) as well as multiple indicators of adjustment (e.g., negative affect, feelings of competence, self-esteem) are taken into consideration. Parental alcohol problems are found to be associated with low family cohesion, poor family organization, and low global self-worth of the child. A mediational analysis reveals that the relation between parental drinking and low global self-worth is mediated by family cohesion.

2017-01-01

Critical care nurses are vital to promoting family engagement in the intensive care unit. However, nurses have varying perceptions about how much family members should be involved. The Questionnaire on Factors That Influence Family Engagement was given to a national sample of 433 critical care nurses. This correlational study explored the impact of nurse and organizational characteristics on barriers and facilitators to family engagement. Study results indicate that (1) nurses were most likely to invite family caregivers to provide simple daily care; (2) age, degree earned, critical care experience, hospital location, unit type, and staffing ratios influenced the scores; and (3) nursing work-flow partially mediated the relationships between the intensive care unit environment and nurses' attitudes and between patient acuity and nurses' attitudes. These results help inform nursing leaders on ways to promote nurse support of active family engagement in the intensive care unit. ©2017 American Association of Critical-Care Nurses.

The HD-Zip family has a diversity of functions during plant development. In this study, we identify 33 HD-Zip transcription factors in grape and detect their expressions in ovules and somatic embryos, as well as in various vegetative organs. A genome-wide survey for HD-Zip transcription factors in Vitis was conducted based on the 12 X grape genome (V. vinifera L.). A total of 33 members were identified and classified into four subfamilies (I-IV) based on phylogeny analysis with Arabidopsis, rice and maize. VvHDZs in the same subfamily have similar protein motifs and intron/exon structures. An evaluation of duplication events suggests several HD-Zip genes arose before the divergence of the grape and Arabidopsis lineages. The 33 members of HD-Zip were differentially expressed in ovules of the stenospermic grape, Thompson Seedless and of the seeded grape, Pinot noir. Most have higher expressions during ovule abortion in Thompson Seedless. In addition, transcripts of the HD-Zip family were also detected in somatic embryogenesis of Thompson Seedless and in different vegetative organs of Thompson Seedless at varying levels. Additionally, VvHDZ28 is located in the nucleus and had transcriptional activity consistent with the typical features of the HD-Zip family. Our results provide a foundation for future grape HD-Zip gene function research. The identification and expression profiles of the HD-Zip transcription factors in grape, reveal their diverse roles during ovule abortion and organ development. Our results lay a foundation for functional analysis of grape HDZ genes.

Staff Factors Contributing to Family Satisfaction with Long-Term Dementia Care: A Systematic Review of the Literature.

Law, Katharine; Patterson, Tom G; Muers, Jane

2017-01-01

The aim of the present review was to critically evaluate empirical evidence regarding staff factors that contribute to families' satisfaction with ongoing care provision for their relatives with dementia in long-term care. Four databases were systematically searched using search terms informed by the aim of the present systematic review. The resulting 14 relevant articles comprised both qualitative and quantitative studies. The findings highlighted three broad areas relating to staff factors that appeared to contribute to families' satisfaction with care provision: family related factors, relating to staff interaction with families; staffing related factors, focusing on staffing organization and composition; and client related factors, focusing on staff interaction with clients and the quality of care provided. The findings have important implications for care staff and managers working in such settings regarding staffing organization, staff training, recruitment and retention. Future research directions are discussed. Families want consistent, knowledgeable staff that interact well and respond appropriately to the needs of their relative as well as their own needs as family members. Staff training in such settings should therefore focus not only on staff education but also on the importance of establishing effective relationships with both clients and families.

2012-05-01

In this study, the authors investigated whether ADHD and oppositional defiant disorder (ODD) behaviors share associations with problems in cognitive functioning and/or family risk factors in adolescence. This was done by examining independent as well as specific associations of cognitive functioning and family risk factors with ADHD and ODD behaviors. A sample of 120 adolescents from the general population was assessed on various cognitive tasks. ADHD and ODD behaviors were measured through parental and teacher ratings based on Diagnostic and Statistical Manual of Mental Disorders (4th edition) criteria. Parents and adolescents provided information regarding measures of family risk factors. The results show that only cognitive functioning was associated with ADHD behaviors, and family risk factors were, independent of cognitive functioning, associated with ODD behaviors. These results suggest that cognitive performance bears a specific significance for ADHD behaviors, whereas family risk factors have specific importance for ODD behaviors.

Family level phylogenies reveal modes of macroevolution in RNA viruses.

Despite advances in understanding the patterns and processes of microevolution in RNA viruses, little is known about the determinants of viral diversification at the macroevolutionary scale. In particular, the processes by which viral lineages assigned as different "species" are generated remain largely uncharacterized. To address this issue, we use a robust phylogenetic approach to analyze patterns of lineage diversification in five representative families of RNA viruses. We ask whether the process of lineage diversification primarily occurs when viruses infect new host species, either through cross-species transmission or codivergence, and which are defined here as analogous to allopatric speciation in animals, or by acquiring new niches within the same host species, analogous to sympatric speciation. By mapping probable primary host species onto family level viral phylogenies, we reveal a strong clustering among viral lineages that infect groups of closely related host species. Although this is consistent with lineage diversification within individual hosts, we argue that this pattern more likely represents strong biases in our knowledge of viral biodiversity, because we also find that better-sampled human viruses rarely cluster together. Hence, although closely related viruses tend to infect related host species, it is unlikely that they often infect the same host species, such that evolutionary constraints hinder lineage diversification within individual host species. We conclude that the colonization of new but related host species may represent the principle mode of macroevolution in RNA viruses.

It has been proven that high-energy diet with predominance of saturated fatty acids, cholesterol, animal proteins and sugar increases disease incidence. The aim of this study was to determine the potential risk factors of family diet of schoolchildren in Subotica. Evaluation of energy and nutrient intake in family diet (n = 357 families with schoolchildren) was examined by a Food Consumption Questionnaire during 7 days in February-March 1998. Data were elaboreted using a software "NUTQ". The potential nutritive risk factors were determined according to Recommended Dietary Allowances (RDA) index of dietary adequacy, as well as Population Nutrition Goals. Mean energy intake was 2197 kcal, where proteins made 14.64%, fats 41.39% and carbohydrates 43.97%. Mean intake of dietary saturated fatty acids (S) was 11.17%, of polyunsaturated fatty acids (P) 14.39%, of monounsaturated fatty acids 15.82%, dietary cholesterol 82.68 g/1000 kcal, dietary fiber 10.67 g daily, while the P/S ratio was 1.28. Analytical questionnaire of schoolchildren family diet shows that daily about 7.5% of children take in more than 30% of fats, 7% of them over 300 mg of dietary cholesterol, 65% of them over 10% of refined sugars, 50% of them over 10% of saturated fatty acids and all of them more than 6 g of NaCl and less than 20 g of dietary fiber a day. According to WHO recommendations, the average daily energy intake values are appropriate for boys, but exceeding for girls aged ten. Domination of meat, meat products, fats, oils, sugars, as well as mean intake of total fats, saturated fatty acids, potassium and sodium, represent potential nutritive risk factors for developing cardiovascular diseases, which are at the first place of morbidity and the second cause of mortality. In regard to our data from 1998, which have shown that among schoolchildren (n = 478) 10.04% boys and 11.47% girls were obese, 8.55% boys and 6.42% girls were overweight, 9.15% had hypercholesterolemia, 14.83% had

A combination of 454 pyrosequencing and Sanger sequencing was used to sample and characterize the transcriptome of the entomopathogenic oomycete Lagenidium giganteum. More than 50,000 high-throughput reads were annotated through homology searches. Several selected reads served as seeds for the amplification and sequencing of full-length transcripts. Phylogenetic analyses inferred from full-length cellulose synthase alignments revealed that L giganteum is nested within the peronosporalean galaxy and as such appears to have evolved from a phytopathogenic ancestor. In agreement with the phylogeny reconstructions, full-length L. giganteum oomycete effector orthologs, corresponding to the cellulose-binding elicitor lectin (CBEL), crinkler (CRN), and elicitin proteins, were characterized by domain organizations similar to those of pathogenicity factors of plant-pathogenic oomycetes. Importantly, the L. giganteum effectors provide a basis for detailing the roles of canonical CRN, CBEL, and elicitin proteins in the infectious process of an oomycete known principally as an animal pathogen. Finally, phylogenetic analyses and genome mining identified members of glycoside hydrolase family 5 subfamily 27 (GH5_27) as putative virulence factors active on the host insect cuticle, based in part on the fact that GH5_27 genes are shared by entomopathogenic oomycetes and fungi but are underrepresented in nonentomopathogenic genomes. The genomic resources gathered from the L. giganteum transcriptome analysis strongly suggest that filamentous entomopathogens (oomycetes and fungi) exhibit convergent evolution: they have evolved independently from plant-associated microbes, have retained genes indicative of plant associations, and may share similar cores of virulence factors, such as GH5_27 enzymes, that are absent from the genomes of their plant-pathogenic relatives.

Comprehensive Genome-Wide Classification Reveals That Many Plant-Specific Transcription Factors Evolved in Streptophyte Algae

Wilhelmsson, Per K I; Mühlich, Cornelia; Ullrich, Kristian K

2017-01-01

Abstract Plant genomes encode many lineage-specific, unique transcription factors. Expansion of such gene families has been previously found to coincide with the evolution of morphological complexity, although comparative analyses have been hampered by severe sampling bias. Here, we make use of the recently increased availability of plant genomes. We have updated and expanded previous rule sets for domain-based classification of transcription associated proteins (TAPs), comprising transcription factors and transcriptional regulators. The genome-wide annotation of these protein families has been analyzed and made available via the novel TAPscan web interface. We find that many TAP families previously thought to be specific for land plants actually evolved in streptophyte (charophyte) algae; 26 out of 36 TAP family gains are inferred to have occurred in the common ancestor of the Streptophyta (uniting the land plants—Embryophyta—with their closest algal relatives). In contrast, expansions of TAP families were found to occur throughout streptophyte evolution. 17 out of 76 expansion events were found to be common to all land plants and thus probably evolved concomitant with the water-to-land-transition.

To investigate how family members' attitudes toward functional regain, and patients' knowledge and intention of independence influence poststroke rehabilitation. Cross-sectional study. Three rehabilitation inpatient settings. Younger (n=79) and older (n=84) poststroke patients, along with their family members (spouses, n=104; children, n=59). Not applicable. Custom-designed questionnaires were used to tap into the patients' knowledge about rehabilitation (Patient's Rehabilitation Questionnaire-Knowledge About Rehabilitation) and intention of independence (Patient's Rehabilitation Questionnaire-Intention of Independence), and family members' attitudes toward patients in performing basic activities of daily living (BADL) (Family Member Attitudes Questionnaire-BADL) and instrumental activities of daily living (Family Member Attitudes Questionnaire-instrumental activities of daily living). The rehabilitation outcomes included gains in motor, cognitive, and emotional functions, and self-care independence, measured with common clinical instruments. The Family Member Attitudes Questionnaire-BADL predicted cognitive outcome and the Patient's Rehabilitation Questionnaire-Intention of Independence predicted motor outcome for both groups. Differential age-related effects were revealed for the Patient's Rehabilitation Questionnaire-Intention of Independence in predicting emotional outcome only for the younger group, and self-care independence only for the older group. Patients' intention of independence positively affected motor recovery, while family members' positive attitudes promoted cognitive regain. The findings suggested plausible age-related differences in how patients' intentions affect emotion versus self-care independence outcomes. Future studies should explore strategies for promoting positive attitudes toward independence among patients and family members during poststroke rehabilitation.

Involvement in meal preparation and eating meals with the family are associated with better dietary patterns in adolescents, however little research has included older children or longitudinal study designs. This 3-year longitudinal study examines cross-sectional and longitudinal associations between family food involvement, family dinner meal frequency and dietary patterns during late childhood. Questionnaires were completed by parents of 188 children from Greater Melbourne, Australia at baseline in 2002 (mean age=11.25years) and at follow-up in 2006 (mean age=14.16years). Principal components analysis (PCA) was used to identify dietary patterns. Factor analysis (FA) was used to determine the principal factors from six indicators of family food involvement. Multiple linear regression models were used to predict the dietary patterns of children and adolescents at baseline and at follow-up, 3years later, from baseline indicators of family food involvement and frequency of family dinner meals. PCA revealed two dietary patterns, labeled a healthful pattern and an energy-dense pattern. FA revealed one factor for family food involvement. Cross-sectionally among boys, family food involvement score (β=0.55, 95% CI: 0.02, 1.07) and eating family dinner meals daily (β=1.11, 95% CI: 0.27, 1.96) during late childhood were positively associated with the healthful pattern. Eating family dinner meals daily was inversely associated with the energy-dense pattern, cross-sectionally among boys (β=-0.56, 95% CI: -1.06, -0.06). No significant cross-sectional associations were found among girls and no significant longitudinal associations were found for either gender. Involvement in family food and eating dinner with the family during late childhood may have a positive influence on dietary patterns of boys. No evidence was found to suggest the effects on dietary patterns persist into adolescence. Copyright © 2014 Elsevier Ltd. All rights reserved.

Developmental expression patterns of candidate co-factors for vertebrate Six family transcription factors

Neilson, Karen M.; Pignoni, Francesca; Yan, Bo; Moody, Sally A.

2010-01-01

Six family transcription factors play important roles in craniofacial development. Their transcriptional activity can be modified by co-factor proteins. Two Six genes and one co-factor gene (Eya1) are involved in the human Branchio-otic (BO) and Branchio-otic-renal (BOR) syndromes. However, mutations in Six and Eya genes only account for about half of these patients. To discover potential new causative genes, we searched the Xenopus genome for orthologues of Drosophila co-factor proteins that interact with the fly Six-related factor, SO. We identified 33 Xenopus genes with high sequence identity to 20 of the 25 fly SO-interacting proteins. We provide the developmental expression patterns of the Xenopus orthologues for 11 of the fly genes, and demonstrate that all are expressed in developing craniofacial tissues with at least partial overlap with Six1/Six2. We speculate that these genes may function as Six-interacting partners with important roles in vertebrate craniofacial development and perhaps congenital syndromes. PMID:21089078

Describing the prevalence and severity of caries in schoolchildren attending the John F. Kennedy school in Cartagena and its relationship to family factors. This was a cross-sectional descriptive study of 243 students. Dental caries prevalence was evaluated by DMFT and ceo-d index; caries severity was measured by using ICDAS II 2005 criteria and family variables were ascertained by filling out a questionnaire that included the Family APGAR (adaptation, partnership, growth, affection and resolve) for measuring family functioning. Descriptive statistics were used when analysing relationships and the Chi-square test was used for variables. Caries prevalence was 51 % (45-95 59 %CI). It was shown that 38 % (31-44 95 %CI) of parents had reached secondary school (but not completed it), 44 % (39-54 95 %CI) were living with a partner, 47 % (40-53 95 %CI) had low socioeconomic status, 53 % (47-57 95 %CI) were living in nuclear families, 47 % (41-53 95 %CI) were receiving less than minimum wage income, 66 % (58-70 95 %CI) were affiliated to the government health system and 59 % (52-66 95 %CI) were living in dysfunctional families. Bivariate analysis only revealed statistical significance regarding the fathers incomplete secondary schooling and the presence of dental caries (p=0.04). Even though most variables showed no statistical significance regarding explaining the presence of dental caries, they did provide epidemiologically important indicators which would facilitate decisions being made from a public health standpoint.

Analyses of Sox-B and Sox-E Family Genes in the Cephalopod Sepia officinalis: Revealing the Conserved and the Unusual

Cephalopods provide an unprecedented opportunity for comparative studies of the developmental genetics of organ systems that are convergent with analogous vertebrate structures. The Sox-family of transcription factors is an important class of DNA-binding proteins that are known to be involved in many aspects of differentiation, but have been largely unstudied in lophotrochozoan systems. Using a degenerate primer strategy we have isolated coding sequence for three members of the Sox family of transcription factors from a cephalopod mollusk, the European cuttlefish Sepia officinalis: Sof-SoxE, Sof-SoxB1, and Sof-SoxB2. Analyses of their expression patterns during organogenesis reveals distinct spatial and temporal expression domains. Sof-SoxB1 shows early ectodermal expression throughout the developing epithelium, which is gradually restricted to presumptive sensory epithelia. Expression within the nervous system appears by mid-embryogenesis. Sof-SoxB2 expression is similar to Sof-SoxB1 within the developing epithelia in early embryogenesis, however appears in largely non-overlapping expression domains within the central nervous system and is not expressed in the maturing sensory epithelium. In contrast, Sof-SoxE is expressed throughout the presumptive mesodermal territories at the onset of organogenesis. As development proceeds, Sof-SoxE expression is elevated throughout the developing peripheral circulatory system. This expression disappears as the circulatory system matures, but expression is maintained within undifferentiated connective tissues throughout the animal, and appears within the nervous system near the end of embryogenesis. SoxB proteins are widely known for their role in neural specification in numerous phylogenetic lineages. Our data suggests that Sof-SoxB genes play similar roles in cephalopods. In contrast, Sof-SoxE appears to be involved in the early stages of vasculogenesis of the cephalopod closed circulatory system, a novel role for a member of

Rare mutations, including copy-number variants (CNVs), contribute significantly to autism spectrum disorder (ASD) risk. Although their importance has been established in families with only one affected child (simplex families), the contribution of both de novo and inherited CNVs to ASD in families with multiple affected individuals (multiplex families) is less well understood. We analyzed 1,532 families from the Autism Genetic Resource Exchange (AGRE) to assess the impact of de novo and rare CNVs on ASD risk in multiplex families. We observed a higher burden of large, rare CNVs, including inherited events, in individuals with ASD than in their unaffected siblings (odds ratio [OR] = 1.7), but the rate of de novo events was significantly lower than in simplex families. In previously characterized ASD risk loci, we identified 49 CNVs, comprising 24 inherited events, 19 de novo events, and 6 events of unknown inheritance, a significant enrichment in affected versus control individuals (OR = 3.3). In 21 of the 30 families (71%) in whom at least one affected sibling harbored an established ASD major risk CNV, including five families harboring inherited CNVs, the CNV was not shared by all affected siblings, indicating that other risk factors are contributing. We also identified a rare risk locus for ASD and language delay at chromosomal region 2q24 (implicating NR4A2) and another lower-penetrance locus involving inherited deletions and duplications of WWOX. The genetic architecture in multiplex families differs from that in simplex families and is complex, warranting more complete genetic characterization of larger multiplex ASD cohorts.

PURPOSE: The study seeks to examine whether the relationships among community, family, individual factors, and violent behavior are parallel across race- and gender-specific segments of the adolescent population. METHODS: Data from the National Longitudinal Study of Adolescent Health are analyzed to highlight the complex relationships between inequality, community, family, individual behavior, and violence. RESULTS: The results from robust regression analysis provide evidence that social environmental factors can influence adolescent violence in race- and gender-specific ways. CONCLUSIONS: Findings from this study establish the plausibility of multidimensional models that specify a complex relationship between inequality and adolescent violence. PMID:15101669

Centenarians are a good healthy aging model. Interestingly, centenarians' offspring are prone to achieve longevity. Here we recruited 60 longevity families and investigated the blood biochemical indexes of family members to seek candidate factors associated with familial longevity. First, associations of blood indexes with age were tested. Second, associations of blood parameters in centenarians (CEN) with their first generation of offspring (F1) and F1 spouses (F1SP) were analyzed. Third, genes involved in regulating target factors were investigated. We found that total cholesterol (TC) and triglyceride (TG) increased with age (20-80 years), but decreased in CEN. Similarly, blood urea nitrogen (BUN) and blood creatinine (BCr) increased with age (20-80 years), but were maintained on a plateau in CEN. Importantly, we first revealed dual changes in blood pressure, i.e., decreased diastolic blood pressure but increased systolic blood pressure in CEN, which associated with altered CST3 expression. Genetic analysis revealed a significant association of blood uric acid (BUA) and BCr in CEN with F1 but not with F1SP, suggesting they may be heritable traits. Taken together, our results suggest serum lipids, kidney function and especially diastolic pressure rather than systolic pressure were improved in CEN or their offspring, suggesting these factors may play an important role in familial longevity.

Deployment-related risk factors for suicidal ideation among Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans have received a great deal of attention. Studies show that mental health symptoms mediate the association between most deployment stressors and suicidal ideation; however, family-related factors during deployment are largely unexplored. We examined posttraumatic stress disorder (PTSD) and depression symptoms as mediators of the associations between deployment family support and stress and post-deployment suicidal ideation in combat-exposed OEF/OIF veterans. National cross-sectional mail survey. 1046 veterans responded to the survey. The sample for this study was 978 veterans who experienced combat. Regression-based path analyses were conducted. Family support and stress had direct associations with suicidal ideation. When PTSD and depression symptoms were examined as mediators of these associations, results revealed significant indirect paths through these symptoms. This study contributes to the literature on suicidal ideation risk factors among OEF/OIF veterans. Deployment family support and family stress are associated with suicidal ideation; however these associations occur primarily through mental health symptomatology, consistent with findings observed for other deployment factors. This research supports ongoing efforts to treat mental health symptomatology as a means of suicide prevention.

Previously, we have identified a novel CCCH zinc finger protein family as negative regulators of macrophage activation. To gain an overall insight into the entire CCCH zinc finger gene family and to evaluate their potential role in macrophage activation, here we performed a genome-wide survey of CCCH zinc finger genes in mouse and human. Totally 58 CCCH zinc finger genes in mouse and 55 in human were identified and most of them have not been reported previously. Phylogenetic analysis revealed that the mouse CCCH family was divided into 6 groups. Meanwhile, we employed quantitative real-time PCR to profile their tissue expression patterns in adult mice. Clustering analysis showed that most of CCCH genes were broadly expressed in all of tissues examined with various levels. Interestingly, several CCCH genes Mbnl3, Zfp36l2, Zfp36, Zc3h12a, Zc3h12d, Zc3h7a and Leng9 were enriched in macrophage-related organs such as thymus, spleen, lung, intestine and adipose. Consistently, a comprehensive assessment of changes in expression of the 58 members of the mouse CCCH family during macrophage activation also revealed that these CCCH zinc finger genes were associated with the activation of bone marrow-derived macrophages by lipopolysaccharide. Taken together, this study not only identified a functional module of CCCH zinc finger genes in the regulation of macrophage activation but also provided the framework for future studies to dissect the function of this emerging gene family.

To assess the theoretical impact of lifestyle of a cancer family history in first-degree relatives (CFH) and clarify interactions between CFH and lifestyle factors, hospital-based comparison and case-reference studies were conducted in Nagoya, Japan. Totals of 1988 gastric, 2455 breast, 1398 lung and 1352 colorectal cancer patients, as well as 50,706 non-cancer outpatients collected from 1988 to 1998, were checked for lifestyle factors, which included dietary and physical exercise habits, as well as smoking/drinking status. General lifestyle factors with non-cancer outpatients did not differ by the CFH status. Case-reference analyses showed that frequent intake of fruits, raw vegetables, carrots, pumpkin, cabbage and lettuce, as well as frequent physical exercise, were associated with decreased risk for all four sites of cancer, while habitual smoking increasing the risk of gastric, and more particularly, lung cancer. Interestingly, the study revealed the magnitude of odds ratios for the above lifestyle factors obtained from CFH positives to be similar to those from CFH negatives for these four sites of cancer. There were no significant interactions between CFH and any particular lifestyle factor. In conclusion, our results suggest no appreciable influence of CFH on lifestyle related risk factors for gastric, breast, lung, and colorectal cancer. Habitual smoking increased, while frequent physical exercise and raw vegetables intake decreased cancer risk, regardless of the CFH status.

The neprilysin (M13) family of endopeptidases are zinc-metalloenzymes, the majority of which are type II integral membrane proteins. The best characterised of this family is neprilysin, which has important roles in inactivating signalling peptides involved in modulating neuronal activity, blood pressure and the immune system. Other family members include the endothelin converting enzymes (ECE-1 and ECE-2), which are responsible for the final step in the synthesis of potent vasoconstrictor endothelins. The ECEs, as well as neprilysin, are considered valuable therapeutic targets for treating cardiovascular disease. Other members of the M13 family have not been functionally characterised, but are also likely to have biological roles regulating peptide signalling. The recent sequencing of animal genomes has greatly increased the number of M13 family members in protein databases, information which can be used to reveal evolutionary relationships and to gain insight into conserved biological roles. The phylogenetic analysis successfully resolved vertebrate M13 peptidases into seven classes, one of which appears to be specific to mammals, and insect genes into five functional classes and a series of expansions, which may include inactive peptidases. Nematode genes primarily resolved into groups containing no other taxa, bar the two nematode genes associated with Drosophila DmeNEP1 and DmeNEP4. This analysis reconstructed only one relationship between chordate and invertebrate clusters, that of the ECE sub-group and the DmeNEP3 related genes. Analysis of amino acid utilisation in the active site of M13 peptidases reveals a basis for their biochemical properties. A relatively invariant S1' subsite gives the majority of M13 peptidases their strong preference for hydrophobic residues in P1' position. The greater variation in the S2' subsite may be instrumental in determining the specificity of M13 peptidases for their substrates and thus allows M13 peptidases to fulfil a

Cap'n'collar (CNC) family basic leucine zipper transcription factors play crucial roles in the regulation of mammalian gene expression and development. To determine the in vivo function of the CNC protein Nrf3 (NF-E2-related factor 3), we generated mice deficient in this transcription factor. We performed targeted disruption of two Nrf3 exons coding for CNC homology, basic DNA-binding, and leucine zipper dimerization domains. Nrf3 null mice developed normally and revealed no obvious phenotypic differences compared to wild-type animals. Nrf3(-/-) mice were fertile, and gross anatomy as well as behavior appeared normal. The mice showed normal age progression and did not show any apparent additional phenotype during their life span. We observed no differences in various blood parameters and chemistry values. We infected wild-type and Nrf3(-/-) mice with acute lymphocytic choriomeningitis virus and found no differences in these animals with respect to their number of virus-specific CD8 and CD4 T cells as well as their B-lymphocyte response. To determine whether the mild phenotype of Nrf3 null animals is due to functional redundancy, we generated mice deficient in multiple CNC factors. Contrary to our expectations, an absence of Nrf3 does not seem to cause additional lethality in compound Nrf3(-/-)/Nrf2(-/-) and Nrf3(-/-)/p45(-/-) mice. We hypothesize that the role of Nrf3 in vivo may become apparent only after appropriate challenge to the mice.

Family-related variables included: (a) parent status (e.g., socioeconomic status and mental health), (b) parent-child relationship (e.g., warmth, conflict, and abuse), (c) parental influence on gaming (e.g., supervision of gaming, modeling, and attitudes toward gaming), and (d) family environment (e.g., household composition). Results The majority of studies have focused on parent-child relationships, reporting that poorer quality relationships are associated with increased severity of problem gaming. The paternal relationship may be protective against problem gaming; therefore, prevention programs should leverage the support of cooperative fathers. Discussion The intergenerational effects of problem gaming require further attention, in light of adult gamers raising their children in a gaming-centric environment. Research has been limited by a reliance on adolescent self-report to understand family dynamics, without gathering corroborating information from parents and other family members. The very high rates of problem gaming (>10%) reported in general population samples raise concerns about the validity of current screening tools. Conclusions Interventions for adolescents may be more effective in some cases if they can address familial influences on problem gaming with the active co-participation of parents, rather than enrolling vulnerable adolescents in individual-based training or temporarily isolating adolescents from the family system.

2017-01-01

Although discriminating self from nonself is a cardinal animal trait, metazoan allorecognition genes do not appear to be homologous. Here, we characterize the Aggregation Factor (AF) gene family, which encodes putative allorecognition factors in the demosponge Amphimedon queenslandica, and trace its evolution across 24 sponge (Porifera) species. The AF locus in Amphimedon is comprised of a cluster of five similar genes that encode Calx-beta and Von Willebrand domains and a newly defined Wreath domain, and are highly polymorphic. Further AF variance appears to be generated through individualistic patterns of RNA editing. The AF gene family varies between poriferans, with protein sequences and domains diagnostic of the AF family being present in Amphimedon and other demosponges, but absent from other sponge classes. Within the demosponges, AFs vary widely with no two species having the same AF repertoire or domain organization. The evolution of AFs suggests that their diversification occurs via high allelism, and the continual and rapid gain, loss and shuffling of domains over evolutionary time. Given the marked differences in metazoan allorecognition genes, we propose the rapid evolution of AFs in sponges provides a model for understanding the extensive diversification of self–nonself recognition systems in the animal kingdom.

The basic leucine zipper (bZIP) transcription factor family plays crucial roles in various aspects of biological processes. Currently, no information is available regarding the bZIP family in the important tropical crop cassava. Herein, 77 bZIP genes were identified from cassava. Evolutionary analysis indicated that MebZIPs could be divided into 10 subfamilies, which was further supported by conserved motif and gene structure analyses. Global expression analysis suggested that MebZIPs showed similar or distinct expression patterns in different tissues between cultivated variety and wild subspecies. Transcriptome analysis of three cassava genotypes revealed that many MebZIP genes were activated by drought in the root of W14 subspecies, indicating the involvement of these genes in the strong resistance of cassava to drought. Expression analysis of selected MebZIP genes in response to osmotic, salt, cold, ABA, and H2O2 suggested that they might participate in distinct signaling pathways. Our systematic analysis of MebZIPs reveals constitutive, tissue-specific and abiotic stress-responsive candidate MebZIP genes for further functional characterization in planta, yields new insights into transcriptional regulation of MebZIP genes, and lays a foundation for understanding of bZIP-mediated abiotic stress response.

Frequent family mealtimes have been associated with numerous positive dietary, health, and behavioral outcomes for children and families. This review article summarizes some of the beneficial outcomes associated with having frequent family dinners. Current trends in family dinner frequency are discussed in the context of barriers that influence how often families eat dinner together, including time issues, work issues, and distractions in the home environment. Next, several parental influences and home environment factors that promote healthy and consistent family dinners are outlined. Finally, limitations are discussed and a few practical suggestions are mentioned to help encourage families, employers, and policy-makers to make family mealtimes a regular practice for as many families as possible.

2018-04-01

Insights into disclosure by people living with HIV and AIDS (PLWHA) can inform strategies for treatment and support, yet Vietnamese women's self-disclosure patterns are poorly understood. We conducted interviews with 12 HIV-positive women, identifying three principal factors influencing disclosure to family members: patrilocal residence, desire to protect own family, and the need for financial support. Women's decision-making about disclosure was significantly affected by dependence on or independence of parents-in-law and their own parents. We believe that our findings reveal the complex interplay of stigma and disclosure within Vietnamese families, highlighting the need for specific social measures that promote self-disclosure combined with family support for female PLWHA.

Family Structure and Family Processes in Mexican American Families

2010-01-01

Despite increases in single-parent families among Mexican Americans (MA), few studies have examined the association of family structure and family adjustment. Utilizing a diverse sample of 738 Mexican American families (21.7% single parent), the current study examined differences across family structure on early adolescent outcomes, family functioning, and parent-child relationship variables. Results revealed that early adolescents in single parent families reported greater school misconduct, CD/ODD and MDD symptoms, and greater parent-child conflict than their counterparts in two parent families. Single parent mothers reported greater economic hardship, depression and family stress. Family stress and parent-child conflict emerged as significant mediators of the association between family structure and early adolescent outcomes, suggesting important processes linking MA single parent families and adolescent adjustment.

2013-07-01

The present study utilized data from the National Latino and Asian American Study to examine ethnic and generational differences in family cultural conflict and family cohesion and how the effects of such family conflict and cohesion on lifetime service use vary by generation status for Latino Americans (n = 2,554) and Asian Americans (n = 2,095). Findings revealed that first-generation Asian Americans reported greater family cultural conflict than their Latino counterparts, but third-generation Latino Americans had higher family conflict than their Asian American counterparts. First-generation Latino and Asian Americans had the highest levels of family cohesion. Results from logistic regression analyses indicated that Latino Americans who reported higher family cultural conflict and lower family cohesion were more likely to use mental health services. For Asian Americans, family cultural conflict, but not family cohesion, was associated with service use. Relative to third-generation Asian Americans, second-generation Asian Americans with higher family cultural conflict were more likely to use mental health services. Given that cohesive familial bonds appear to discourage service use on the part of Latino Americans irrespective of generation status, further research is needed to ascertain the extent to which this tendency stems from greater reliance on family support as opposed to the stigma associated with mental health treatment. Mental health providers and treatment programs need to address the role of family cultural conflict in the lives of Asian Americans, particularly second generation, and Latino Americans across generations, because conflictual family ties may motivate help-seeking behaviors and reveal substantial underlying distress.

The current investigation addressed the potential for unique influences of perceived childhood maltreatment, adverse family-life events, and parent-child relational trauma on the lifetime occurrence and addictive features of non-suicidal self-injury (NSSI). Participants included 957 undergraduate students (747 females; M = 20.14 years, SD = 3.88) who completed online questionnaires regarding the key variables under study. Although self-injuring youth reported more experiences with each family-based risk factor, different patterns of association were found when lifetime engagement in NSSI or its addictive features were under study. Perceived parent-child relational trauma was uniquely linked with NSSI behavior after accounting for perceived childhood maltreatment; adverse family-life events had an additional unique association. In contrast, perceived paternal maltreatment was uniquely related with NSSI's addictive features. Findings underline the importance of studying inter-related family-based risk factors of NSSI simultaneously for a comprehensive understanding of familial correlates of NSSI behavior and its underlying features.

AIM To make comprehensive molecular diagnosis for retinitis pigmentosa (RP) patients in a consanguineous Han Chinese family using next generation sequencing based Capture-NGS screen technology. METHODS A five-generation Han Chinese family diagnosed as non-syndromic X-linked recessive RP (XLRP) was recruited, including four affected males, four obligate female carriers and eleven unaffected family members. Capture-NGS was performed using a custom designed capture panel covers 163 known retinal disease genes including 47 RP genes, followed by the validation of detected mutation using Sanger sequencing in all recruited family members. RESULTS Capture-NGS in one affected 47-year-old male reveals a novel mutation, c.2417_2418insG:p.E806fs, in exon ORF15 of RP GTPase regulator (RPGR) gene results in a frameshift change that results in a premature stop codon and a truncated protein product. The mutation was further validated in three of four affected males and two of four female carriers but not in the other unaffected family members. CONCLUSION We have identified a novel mutation, c.2417_2418insG:p.E806fs, in a Han Chinese family with XLRP. Our findings expand the mutation spectrum of RPGR and the phenotypic spectrum of XLRP in Han Chinese families, and confirms Capture-NGS could be an effective and economic approach for the comprehensive molecular diagnosis of RP.

Internet addiction (IA) among adolescents has become a global health problem, and public awareness of it is increasing. Many IA risk factors relate to parents and the family environment. This study examined the relationship between IA and parenting approaches and family functionality. A cross-sectional study was conducted with 2021 secondary students to identify the prevalence of IA and to explore the association between adolescent IA and familial variables, including parents' marital status, family income, family conflict, family functionality, and parenting approaches. The results revealed that 25.3 % of the adolescent respondents exhibited IA, and logistic regression positively predicted the IA of adolescents from divorced families, low-income families, families in which family conflict existed, and severely dysfunctional families. Interestingly, adolescents with restricted Internet use were almost 1.9 times more likely to have IA than those whose use was not restricted. Internet addiction is common among Chinese adolescents in Hong Kong, and family-based prevention strategies should be aligned with the risk factors of IA.

Understanding the level of public satisfaction with a family physician plan as well as the relevant factors in this respect, can be employed as valuable tools in identifying quality of services. To determine the factors affecting public dissatisfaction with an urban family physician plan in Iran. This cross-sectional study was conducted from January 2014 through June 2015 on Fars Province residents in Iran, selected based on cluster sampling method. The data collection instrument was comprised of a two-part checklist including demographic information and items related to dissatisfaction with the family physician plan, specialists, para-clinic services, pharmacy, physicians on shift work, emergency services, and family physician assistants. Data were described by SPSS 20. In this study, 1,020 individuals (524 males, 496 females) were investigated. Based on the results, the most frequent factor affecting dissatisfaction with physicians was their single work shifts and unavailability (53%). In terms of dissatisfaction with family physicians' specialist colleagues and para-clinic services, the most common factors were related to difficulty in obtaining a referral form (41.5%) and making appointments (21.6%), respectively. Given the level of dissatisfaction with pharmacies, the significant factor was reported to be excessive delay in medication delivery (31.6%); and in terms of physicians on shift work and emergency services, the most important factor was lower work hours for family physicians (9.2%). It seems that, the most common causes of dissatisfaction with the urban family physician plan are due to the short duration of services, obtaining a referral form and making appointments, and providing prescribed medications.

OBJECTIVE--To study the role of the HLA system in the genetic susceptibility to familial systemic sclerosis (SSc). METHODS--HLA class I antigens were determined by classic serological methods and HLA-DRB, -DQA and -DQB genes were analysed by genetic typing in 36 individuals belonging to two families with several individuals affected by SSc. RESULTS--The results did not show any association of the inheritance to SSc with any particular HLA allele in these families but revealed a striking frequency of ANA autoantibodies in healthy spouses of the members of these families. CONCLUSION--The otherwise infrequent familial incidence of SSc does not appear to be primarily linked to the HLA system in this study but it is suggested that other unknown exogenous environmental factors could be implicated in the development of the disease in families.

The relation of some family characteristics such as cohesion and adaptability with organic risk factors, developmental psychopathology, clinical picture and premorbid adjustment was assessed in the group of 100 hospitalized adolescent patients and families. We found correlation between: some of organic risk factors (pathology of neonatal period, pathology of early childhood), some of indicators of developmental psychopathology (eating disorders, conduct disorders), some of clinical signs (mannerism, grandiosity, hostility, suspciousness, disturbances of content of thinking), premorbid adjustment, and variables related to families, described before. We think that biological variables characterizing child (pathology of neonatal period, pathology of early childhood) have an influence on some family characteristics as independent variable. General system theory and circular thinking support these conclusions. In order to verify them, it is necessary to undertake further investigations, based on other methodology, using this results as preliminary findings.

Whole-genome phylogenies of the family Bacillaceae and expansion of the sigma factor gene family in the Bacillus cereus species-group

PubMed Central

2011-01-01

Background The Bacillus cereus sensu lato group consists of six species (B. anthracis, B. cereus, B. mycoides, B. pseudomycoides, B. thuringiensis, and B. weihenstephanensis). While classical microbial taxonomy proposed these organisms as distinct species, newer molecular phylogenies and comparative genome sequencing suggests that these organisms should be classified as a single species (thus, we will refer to these organisms collectively as the Bc species-group). How do we account for the underlying similarity of these phenotypically diverse microbes? It has been established for some time that the most rapidly evolving and evolutionarily flexible portions of the bacterial genome are regulatory sequences and transcriptional networks. Other studies have suggested that the sigma factor gene family of these organisms has diverged and expanded significantly relative to their ancestors; sigma factors are those portions of the bacterial transcriptional apparatus that control RNA polymerase recognition for promoter selection. Thus, examining sigma factor divergence in these organisms would concurrently examine both regulatory sequences and transcriptional networks important for divergence. We began this examination by comparison to the sigma factor gene set of B. subtilis. Results Phylogenetic analysis of the Bc species-group utilizing 157 single-copy genes of the family Bacillaceae suggests that several taxonomic revisions of the genus Bacillus should be considered. Within the Bc species-group there is little indication that the currently recognized species form related sub-groupings, suggesting that they are members of the same species. The sigma factor gene family encoded by the Bc species-group appears to be the result of a dynamic gene-duplication and gene-loss process that in previous analyses underestimated the true heterogeneity of the sigma factor content in the Bc species-group. Conclusions Expansion of the sigma factor gene family appears to have preferentially

Genetic studies on facial morphology targeting healthy populations are fundamental in understanding the specific genetic influences involved; yet, most studies to date, if not all, have been focused on congenital diseases accompanied by facial anomalies. To study the specific genetic cues determining facial morphology, we estimated familial correlations and heritabilities of 14 facial measurements and 3 latent factors inferred from a factor analysis in a subset of the Korean population. The study included a total of 229 individuals from 38 families. We evaluated a total of 14 facial measurements using 2D digital photographs. We performed factor analysis to infer common latent variables. The heritabilities of 13 facial measurements were statistically significant (p < 0.05) and ranged from 0.25 to 0.61. Of these, the heritability of intercanthal width in the orbital region was found to be the highest (h2 = 0.61, SE = 0.14). Three factors (lower face portion, orbital region, and vertical length) were obtained through factor analysis, where the heritability values ranged from 0.45 to 0.55. The heritability values for each factor were higher than the mean heritability value of individual original measurements. We have confirmed the genetic influence on facial anthropometric traits and suggest a potential way to categorize and analyze the facial portions into different groups. PMID:23843774

Parental psychopathology and family issues are key influence factors to child behaviour problems. This study aimed to investigate the dyadic impact of maternal and paternal depression and perceived family functioning on child behaviour problems. Both maternal and paternal depression, perceived family functioning and reported child behaviour problems were collected, respectively. Because of the interdependent characteristic of dyadic data, structural equation modelling was used to examine the relationship among all variables and the mutual influence between mother and father. Results showed that father-perceived family functioning mediated the relationship between parental depression and child behaviour problems, but mother-perceived family functioning did not show this mediation effect. Meanwhile, maternal and paternal depression influenced both of their own and their partner's perceived family functioning. The findings indicated that paternal psychopathology and family functioning should not be overlooked in child behaviour development. In addition, this study underscored the importance to investigate the different impact of father and mother on child development within a dyadic unit. © 2014 John Wiley & Sons Ltd.

Caregiver mental health is widely considered to be an important factor influencing children's asthma symptoms. The present study aimed to examine key factors that contribute to caregiver mental health in pediatric asthma with a Chinese sample. Two hundred participants reported their family socioeconomic status (SES), proneness to shame, asthma symptoms control of their child, family functioning, and their depression and anxiety symptoms. Results suggested that low family SES, low family functioning, and a high level of shame proneness were associated with high levels of anxiety and depression for caregivers. Family functioning mediated the effects of SES and shame on caregiver mental health and also moderated the effects of SES and shame on caregiver depression. This study highlights the importance of reducing experience of shame and enhancing family functioning in families affected by pediatric asthma. © 2014 Family Process Institute.

This study aimed at evaluating the effect of family factors on the occurrence of Internet addiction and determining whether Internet addiction could make any difference in the family function. A total of 2293 adolescents in grade 7 participated in the study. We assessed their Internet addiction, family function, and family factors with a 1-year follow up. In the prospective investigation, inter-parental conflict predicted the incidence of Internet addiction 1 year later in forward regression analysis, followed by not living with mother and allowance to use Internet more than 2 h per day by parents or caregiver. The inter-parental conflict and allowance to use Internet more than 2 h per day also predicted the incidence in girls. Not cared for by parents and family APGAR score predicted the incidence of Internet addiction among boys. The prospective investigation demonstrated that the incidence group had more decreased scores on family APGAR than did the non-addiction group in the 1-year follow-up. This effect was significant only among girls. Inter-parental conflict and inadequate regulation of unessential Internet use predicted risk of Internet addiction, particularly among adolescent girls. Family intervention to prevent inter-parental conflict and promote family function and Internet regulation were necessary to prevent Internet addiction. Among adolescents with Internet addiction, it is necessary to pay attention to deterioration of family function, particularly among girls. © 2014 The Authors.

2018-01-01

Over the last decade there has been an increased focus on improving father engagement to improve child and family outcomes. Recent research suggests that child and family outcomes improve with increased fatherhood engagement. This exploratory study examined risk and protective factors associated with approval of family violence among a sample of low-income fathers (N = 686) enrolled in a responsible fatherhood program. The program goals include increasing father involvement and economic stability and encouraging healthy relationships-with a focus on preventing intimate partner violence. Toward these aims, this study explored factors associated with fathers' self-reported approval of family violence. Understanding the prevalence of risk and protective factors in this population and factors associated with fathers' potential for family violence is important in developing programs to address responsible fatherhood and healthy relationships. © 2017 National Association of Social Workers.

Auxin is a central hormone involved in a wide range of developmental processes including the specification of vascular stem cells. Auxin Response Factors (ARF) are important actors of the auxin signalling pathway, regulating the transcription of auxin-responsive genes through direct binding to their promoters. The recent availability of the Eucalyptus grandis genome sequence allowed us to examine the characteristics and evolutionary history of this gene family in a woody plant of high economic importance. With 17 members, the E. grandis ARF gene family is slightly contracted, as compared to those of most angiosperms studied hitherto, lacking traces of duplication events. In silico analysis of alternative transcripts and gene truncation suggested that these two mechanisms were preeminent in shaping the functional diversity of the ARF family in Eucalyptus. Comparative phylogenetic analyses with genomes of other taxonomic lineages revealed the presence of a new ARF clade found preferentially in woody and/or perennial plants. High-throughput expression profiling among different organs and tissues and in response to environmental cues highlighted genes expressed in vascular cambium and/or developing xylem, responding dynamically to various environmental stimuli. Finally, this study allowed identification of three ARF candidates potentially involved in the auxin-regulated transcriptional program underlying wood formation. PMID:25269088

Comorbidity challenges the notion of mental disorders as discrete categories. An increasing body of literature shows that symptoms cut across traditional diagnostic boundaries and interact in shaping the latent structure of psychopathology. Using exploratory and confirmatory factor analysis, we reveal the latent sources of covariation among nine measures of psychopathological functioning in a population-based sample of 13024 Finnish twins and their siblings. By implementing unidimensional, multidimensional, second-order, and bifactor models, we illustrate the relationships between observed variables, specific, and general latent factors. We also provide the first investigation to date of measurement invariance of the bifactor model of psychopathology across gender and age groups. Our main result is the identification of a distinct "Body" factor, alongside the previously identified Internalizing and Externalizing factors. We also report relevant cross-disorder associations, especially between body-related psychopathology and trait anger, as well as substantial sex and age differences in observed and latent means. The findings expand the meta-structure of psychopathology, with implications for empirical and clinical practice, and demonstrate shared mechanisms underlying attitudes towards nutrition, self-image, sexuality and anger, with gender- and age-specific features.

Aggressive chemotherapy protocols result in neutropenia in approximately half of all patients receiving chemotherapy. Thus, neutropenia continues to be a significant and potentially life-threatening side effect of treatment, even with use of colony-stimulating factors. Families of patients with neutropenia often provide the primary healing environment because most chemotherapy protocols are managed on an outpatient basis. To learn about the family's experience of managing chemotherapy-induced neutropenia (CIN), a grounded-theory methodology was used to analyze data from seven families. The central theme revealed by these families was "turbulent waiting with intensified connections." This meant that when families had a sense of greater vulnerability in response to the waiting after diagnosis of CIN, they connected intensely with each other and healthcare providers. Families reported that connections with nurses became more significant when neutropenia interrupted chemotherapy. Families also developed family caring strategies to manage this period of waiting for the chemotherapy to resume. These strategies included family inquiry, family vigilance, and family balancing. Nurses need to be aware of approaches to support the family's ability to manage CIN. Interventions and approaches constructed from the perspective of a family-professional partnership will enhance the family cancer experience as well as ongoing family growth and function.

Although discriminating self from nonself is a cardinal animal trait, metazoan allorecognition genes do not appear to be homologous. Here, we characterize the Aggregation Factor (AF) gene family, which encodes putative allorecognition factors in the demosponge Amphimedon queenslandica, and trace its evolution across 24 sponge (Porifera) species. The AF locus in Amphimedon is comprised of a cluster of five similar genes that encode Calx-beta and Von Willebrand domains and a newly defined Wreath domain, and are highly polymorphic. Further AF variance appears to be generated through individualistic patterns of RNA editing. The AF gene family varies between poriferans, with protein sequences and domains diagnostic of the AF family being present in Amphimedon and other demosponges, but absent from other sponge classes. Within the demosponges, AFs vary widely with no two species having the same AF repertoire or domain organization. The evolution of AFs suggests that their diversification occurs via high allelism, and the continual and rapid gain, loss and shuffling of domains over evolutionary time. Given the marked differences in metazoan allorecognition genes, we propose the rapid evolution of AFs in sponges provides a model for understanding the extensive diversification of self-nonself recognition systems in the animal kingdom. © The Author 2017.

Disadvantaged neighborhoods confer risk for behavior problems in school aged children but their impact in toddlerhood is unknown. Relations between toddlers’ disruptive behavior and neighborhood disadvantage, family disadvantage, violence or conflict exposure, parent depressive symptoms, and parenting behavior were examined using multilevel, multi-group (girl/boy) models. Participants were 1204 families (mean child age = 24.7 months). Unique associations between disruptive behavior and all risk factors were observed, but the effect of neighborhood disadvantage was negligible when all of the more proximal factors were accounted for. The results suggest both that children in disadvantaged neighborhoods are at greater risk of behavior problems than children in non-disadvantaged neighborhoods and that optimal prevention/intervention work with these children will attend to proximal risk factors.

Autism is a pervasive neurodevelopmental disorder diagnosed in early childhood. Growth factors have been found to play a key role in the cellular differentiation and proliferation of the central and peripheral nervous systems. Epidermal growth factor (EGF) is detected in several regions of the developing and adult brain, where, it enhances the differentiation, maturation, and survival of a variety of neurons. Transforming growth factor-{beta} (TGF{beta}) isoforms play an important role in neuronal survival, and the hepatocyte growth factor (HGF) has been shown to exhibit neurotrophic activity. We examined the association of EGF, TGF{beta}1, and HGF genes with autism, in amore » trio association study, using DNA samples from families recruited to the Autism Genetic Resource Exchange; 252 trios with a male offspring scored for autism were selected for the study. Transmission disequilibrium test revealed significant haplotypic association of EGF with autism. No significant SNP or haplotypic associations were observed for TGF{beta}1 or HGF. Given the role of EGF in brain and neuronal development, we suggest a possible role of EGF in the pathogenesis of autism.« less

Members of the tumor necrosis factor (TNF) family induce pleiotropic biological responses, including cell growth, differentiation, and even death. Here we describe a novel member of the TNF family, designated BAFF (for B cell activating factor belonging to the TNF family), which is expressed by T cells and dendritic cells. Human BAFF was mapped to chromosome 13q32-34. Membrane-bound BAFF was processed and secreted through the action of a protease whose specificity matches that of the furin family of proprotein convertases. The expression of BAFF receptor appeared to be restricted to B cells. Both membrane-bound and soluble BAFF induced proliferation of anti-immunoglobulin M–stimulated peripheral blood B lymphocytes. Moreover, increased amounts of immunoglobulins were found in supernatants of germinal center–like B cells costimulated with BAFF. These results suggest that BAFF plays an important role as costimulator of B cell proliferation and function. PMID:10359578

Factors Associated With Higher Caregiver Burden Among Family Caregivers of Elderly Cancer Patients: A Systematic Review.

PubMed

Ge, Lixia; Mordiffi, Siti Zubaidah

Caring for elderly cancer patients may cause multidimensional burden on family caregivers. Recognition of factors associated with caregiver burden is important for providing proactive support to caregivers at risk. The aim of this study was to identify factors associated with high caregiver burden among family caregivers of elderly cancer patients. A systematic search of 7 electronic databases was conducted from database inception to October 2014. The identified studies were screened, and full text was further assessed. The quality of included studies was assessed using a checklist, and relevant data were extracted using a predeveloped data extraction form. Best-evidence synthesis model was used for data synthesis. The search yielded a total of 3339 studies, and 7 studies involving 1233 family caregivers were included after screening and full assessment of 116 studies. Moderate evidence supported that younger caregivers, solid tumors, and assistance with patient's activities of daily living were significantly associated with high caregiver burden. Eighteen factors were supported by limited evidence, and 1 was a conflicting factor. The scientific literature to date proved that caregiver burden was commonly experienced by family caregivers of elderly cancer patients. The evidence indicated that family caregivers who were at younger age, caring for solid tumor patients, and providing assistance with patient's activities of daily living reported high caregiver burden. The data provide evidence in identifying family caregivers at high risk of high caregiver burden. More high-quality studies are needed to clarify and determine the estimates of the effects of individual factors.

Family factors related to children's intrinsic/extrinsic motivational orientation and academic performance.

This study examined 3 familial factors--parental surveillance of homework, parental reactions to grades, and general family style--in relation to children's motivational orientation and academic performance. Family, parent, and child measures were obtained in the home from 93 fifth graders and their parents. Teachers provided a measure of classroom motivational orientation, and grades and achievement scores were obtained from school records. Higher parental surveillance of homework, parental reactions to grades that included negative control, uninvolvement, or extrinsic reward, and over- and undercontrolling family styles were found to be related to an extrinsic motivational orientation and to lower academic performance. On the other hand, parental encouragement in response to grades children received was associated with an intrinsic motivational orientation, and autonomy-supporting family styles were associated with intrinsic motivation and higher academic performance. In addition, socioeconomic level was a significant predictor of motivational orientation and academic performance.

Computing rank-revealing QR factorizations of dense matrices.

We develop algorithms and implementations for computing rank-revealing QR (RRQR) factorizations of dense matrices. First, we develop an efficient block algorithm for approximating an RRQR factorization, employing a windowed version of the commonly used Golub pivoting strategy, aided by incremental condition estimation. Second, we develop efficiently implementable variants of guaranteed reliable RRQR algorithms for triangular matrices originally suggested by Chandrasekaran and Ipsen and by Pan and Tang. We suggest algorithmic improvements with respect to condition estimation, termination criteria, and Givens updating. By combining the block algorithm with one of the triangular postprocessing steps, we arrive at an efficient and reliablemore » algorithm for computing an RRQR factorization of a dense matrix. Experimental results on IBM RS/6000 SGI R8000 platforms show that this approach performs up to three times faster that the less reliable QR factorization with column pivoting as it is currently implemented in LAPACK, and comes within 15% of the performance of the LAPACK block algorithm for computing a QR factorization without any column exchanges. Thus, we expect this routine to be useful in may circumstances where numerical rank deficiency cannot be ruled out, but currently has been ignored because of the computational cost of dealing with it.« less

Who's on base? Revealing the catalytic mechanism of inverting family 6 glycoside hydrolases

Mayes, Heather B.; Knott, Brandon C.; Crowley, Michael F.

In several important classes of inverting carbohydrate-active enzymes, the identity of the catalytic base remains elusive, including in family 6 Glycoside Hydrolase (GH6) enzymes, which are key components of cellulase cocktails for cellulose depolymerization. Despite many structural and kinetic studies with both wild-type and mutant enzymes, especially on the Trichoderma reesei (Hypocrea jecorina) GH6 cellulase ( TrCel6A), the catalytic base in the single displacement inverting mechanism has not been definitively identified in the GH6 family. Here, we employ transition path sampling to gain insight into the catalytic mechanism, which provides unbiased atomic-level understanding of key order parameters involved in cleavingmore » the strong glycosidic bond. Our hybrid quantum mechanics and molecular mechanics (QM/MM) simulations reveal a network of hydrogen bonding that aligns two active site water molecules that play key roles in hydrolysis: one water molecule drives the reaction by nucleophilic attack on the substrate and a second shuttles a proton to the putative base (D175) via a short water wire. We also investigated the case where the putative base is mutated to an alanine, an enzyme that is experimentally still partially active. The simulations predict that proton hopping along a water wire via a Grotthuss mechanism provides a mechanism of catalytic rescue. Further simulations reveal that substrate processive motion is 'driven' by strong electrostatic interactions with the protein at the product sites and that the -1 sugar adopts a 2S O ring configuration as it reaches its binding site. Lastly, this work thus elucidates previously elusive steps in the processive catalytic mechanism of this important class of enzymes.« less

The APOBEC3 Family of Retroelement Restriction Factors

PubMed Central

Refsland, Eric W.; Harris, Reuben S.

2014-01-01

The ability to regulate and even target mutagenesis is an extremely valuable cellular asset. Enzyme-catalyzed DNA cytosine deamination is a molecular strategy employed by vertebrates to promote antibody diversity and defend against foreign nucleic acids. Ten years ago, a family of cellular enzymes was first described with several proving capable of deaminating DNA and inhibiting HIV-1 replication. Ensuing studies on the apolipoprotein B mRNA-editing enzyme catalytic polypeptide-like 3 (APOBEC3) restriction factors have uncovered a broad-spectrum innate defense network that suppresses the replication of numerous endogenous and exogenous DNA-based parasites. Although many viruses possess equally elaborate counter-defense mechanisms, the APOBEC3 enzymes offer a tantalizing possibility of leveraging innate immunity to fend off viral infection. Here we focus on mechanisms of retroelement restriction by the APOBEC3 family of restriction enzymes and we consider the therapeutic benefits, as well as the possible pathological consequences, of arming cells with active DNA deaminases.

The aim of the present study was to analyze predictive factors of post-traumatic stress disorder (PTSD) symptoms in school-aged girls. A group (n=67) of seven- to 12 year-old girls consulting a paediatric hospital following disclosure of sexual abuse were compared with a group (n=67) of nonabused girls. The girls answered questionnaires related to PTSD, coping, sense of hope, self-esteem, sibling relationships and perceived social support. Mothers answered questionnaires related to family relationships, family violence, perceived support given and psychological distress. The mean +/- SD age of the girls was 9+/-1.5 years. In the sexual abuse group, single-parent families were more frequent (53.7% versus 32.3%; P<0.01), mothers were less educated (10.8% versus 13.1%; P<0.0001) and socioeconomic level was lower (36.8% versus 47.9%; P<0.0001). A history of sexual abuse in childhood was reported by 50% of mothers of sexually abused children and 37% of mothers of the comparison group children. A higher prevalence of PTSD clinical scores was found for the girls reporting sexual abuse (46.3% versus 18.5%; P<0.001). Regression analyses controlling for parental education level and family structure revealed that group membership (sexual abuse group versus comparison group) was predictive of the level of PTSD symptoms. In addition, the mother's level of support, the child's perception of parental support and the child's reliance on avoidance coping predicted PTSD symptoms. Sense of hope and the child witnessing interparental physical violence were marginally associated with the level of PTSD symptoms. PTSD was common in the present study's sample of sexually abused girls. Because predictive factors relate to both child-related variables and familial context, interventions for this population should target not only the child, but also the family.

The Zarit Burden Interview has been used in many studies to assess caregiver burden in family caregivers of patients with amyotrophic lateral sclerosis, but the factor structure of the Zarit Burden Interview in the caregivers of amyotrophic lateral sclerosis patients is unknown. The aim of this study was to explore the factor structure of the Zarit Burden Interview in family caregivers of amyotrophic lateral sclerosis patients using exploratory factor analysis. The exploratory factor analysis was performed using generalized least squares with oblique rotation in a sample of 202 family caregivers. Three factors had an eigenvalue greater than 1 and accounted for 60.33% of the total variance. The three factors were named as follows: (factor 1) "Social restrictions" (items 2, 3, and 10-15); (factor 2) "Self-criticism" (items 20-21); and (factor 3) "Anger and frustration" (items 1, 4-6, 9, and 16-19). The correlation between factors 1 and 3 was much higher (r = 0.79) than that between factors 1 and 2 (r = 0.14) or factors 2 and 3 (r = 0.15). The findings of this study enriched our understanding of several meaningful dimensions of the caregiving burden in caregivers of an amyotrophic lateral sclerosis population and provided opportunities for future intervention.

We examined 2 sleep-wake parameters as moderators of the associations between exposure to family stressors and adolescent cognitive functioning. Participants were 252 school-recruited adolescents (M = 15.79 years; 66% European American, 34% African American). Youths reported on 3 dimensions of family stress: marital conflict, harsh parenting, and parental psychological control. Cognitive functioning was indexed through performance on the Woodcock-Johnson III Tests of Cognitive Abilities. Sleep minutes and efficiency were measured objectively using actigraphy. Toward identifying unique effects, path models controlled for 2 family stress variables while estimating the third. Analyses revealed that sleep efficiency moderated the associations between negative parenting (harsh parenting and parental psychological control) and adolescents' cognitive functioning. The highest level of cognitive performance was predicted for adolescents with higher levels of sleep efficiency in conjunction with lower levels of either harsh parenting or psychological control. The effects of sleep were more pronounced at lower levels of negative parenting, in which adolescents with higher sleep efficiency performed better than their counterparts with poorer sleep. At higher levels of either harsh parenting or psychological control, similar levels of cognitive performance were observed regardless of sleep. Results are discussed in comparison with other recent studies on interrelations among family stress, sleep, and cognitive performance in childhood and adolescence.

OBJECTIVES. High rates of family violence and low rates of detection, report, and therapeutic intervention by health professionals are well documented. This study was undertaken to determine what factors influence clinicians' decision making about identifying abuse and intervening with victims. METHODS. Survey data about clinicians' experiences with and attitudes toward family violence were gathered by mailed questionnaire from a random sample of practicing clinicians in six disciplines (n = 1521). RESULTS. Data showed similarities within and wide differences among three groups of subjects: dentists/dental hygienists, nurses/physicians, and psychologists/social workers. Overall, a third of subjects reported having received no educational content on child, spouse, or elder abuse in their professional training programs. Subjects with education on the topic more commonly suspected abuse in their patients than those without; among all subjects, spouse abuse was suspected more often than child abuse while elder abuse was suspected infrequently. Significant numbers of subjects did not view themselves as responsible for dealing with problems of family violence. Subjects indicated low confidence in and low compliance with mandatory reporting laws. CONCLUSIONS. There is a need for educators to expand curricula on family violence and for legislators to reexamine mandatory reporting laws. PMID:8154568

GENERAL REGULATORY FACTOR (GRF) proteins play vital roles in the regulation of plant growth, development, and response to abiotic stress. However, little information is known for this gene family in cassava ( Manihot esculenta ). In this study, 15 MeGRFs were identified from the cassava genome and were clustered into the ε and the non-ε groups according to phylogenetic, conserved motif, and gene structure analyses. Transcriptomic analyses showed eleven Me GRFs with constitutively high expression in stems, leaves, and storage roots of two cassava genotypes. Expression analyses revealed that the majority of GRFs showed transcriptional changes under cold, osmotic, salt, abscisic acid (ABA), and H₂O₂ treatments. Six Me GRFs were found to be commonly upregulated by abiotic stress, ABA, and H₂O₂ treatments, which may be the converging points of multiple signaling pathways. Interaction network analysis identified 18 possible interactors of MeGRFs. Taken together, this study elucidates the transcriptional control of Me GRFs in tissue development and the responses of abiotic stress and related signaling in cassava. Some constitutively expressed, tissue-specific, and abiotic stress-responsive candidate MeGRF genes were identified for the further genetic improvement of crops.

Identification of familial, more homogenous characteristics of obsessive-compulsive disorder (OCD) may help to define relevant subtypes and increase the power of genetic and neurobiological studies of OCD. While factor-analytic studies have found consistent, clinically meaningful OCD symptom dimensions, there have been only limited attempts to evaluate the familiality and potential genetic basis of such dimensions. Four hundred eighteen sibling pairs with OCD were evaluated using the Structured Clinical Interview for DSM-IV and the Yale-Brown Obsessive Compulsive Scale (YBOCS) Symptom Checklist and Severity scales. After controlling for sex, age, and age of onset, robust sib-sib intraclass correlations were found for two of the four YBOCS factors: Factor IV (hoarding obsessions and compulsions (p = .001) and Factor I (aggressive, sexual, and religious obsessions, and checking compulsions; p = .002). Smaller, but still significant, familiality was found for Factor III (contamination/cleaning; p = .02) and Factor II (symmetry/ordering/arranging; p = .04). Limiting the sample to female subjects more than doubled the familiality estimates for Factor II (p = .003). Among potentially relevant comorbid conditions for genetic studies, bipolar I/II and major depressive disorder were strongly associated with Factor I (p < .001), whereas ADHD, alcohol dependence, and bulimia were associated with Factor II (p < .01). Factor-analyzed OCD symptom dimensions in sibling pairs with OCD are familial with some gender-dependence, exhibit relatively specific relationships to comorbid psychiatric disorders and thus may be useful as refined phenotypes for molecular genetic studies of OCD.

Relation of family history and reversible risk factors to coronary heart disease prevalence in an Afrikaner community.

In a cross-sectional study of an Afrikaner community (n = 2,722 men and n = 3,173 women aged 25-64 years), family history of coronary heart disease (CHD) was associated with an adverse risk factor profile and with prevalent CHD. Men with myocardial infarction (MI) and a family history of CHD had higher total minus high density lipoprotein cholesterol (TC-HDLC) levels than men with MI but no CHD family history. In preliminary multiple regression analyses, family history of CHD appeared to exert its effect partly independently of known risk factors and partly dependently through age, TC minus HDLC, and HDLC. Even though their association with MI was weakened after entering family history into the models, the reversible risk factors (particularly TC minus HDLC, HDLC, and uric acid levels) continued to contribute to CHD. For MI in men, there was an interaction between family history of CHD and TC minus HDLC, to the extent that raised TC minus HDLC levels were adverse only in the presence of a positive CHD family history. The findings suggest coinheritance of high blood cholesterol and increased susceptibility to CHD. If confirmed in prospective studies, the interaction between family history and TC minus HDLC will have implications for cholesterol screening and management.

Analysis of cDNA clones that cross-hybridized with the fork head domain of the rat HNF-3 gene family revealed 10 cDNAs from human fetal brain and human testis cDNA libraries containing this highly conserved DNA-binding domain. Three of these cDNAs (HFK1, HFK2, and HFK3) were further analyzed. The cDNA HFK1 has a length of 2557 nucleotides and shows strong homology at the nucleotide level (91.2%) to brain factor 1 (BF-1) from rat. The HFK1 cDNA codes for a putative 476 amino acid protein. The homology to BF-1 from rat in the coding region at the amino acid level is 87.5%. Themore » fork head homologous region includes 111 amino acids starting at amino acid 160 and has a 97.5% homology to BF-1. Southern hybridization revealed that HFK1 is highly conserved among mammalian species and possibly birds. Northern analysis with total RNA from human tissues and poly(A)-rich RNA from mouse revealed a 3.2-kb transcript that is present in human and mouse fetal brain and in adult mouse brain. In situ hybridization with sections of mouse embryo and human fetal brain reveals that HFK1 expression is restricted to the neuronal cells in the telencepthalon, with strong expression being observed in the developing dentate gyrus and hippocampus. HFK1 was chromosomally localized by in situ hybridization to 14q12. The cDNA clones HFK2 and HFK3 were analyzed by restriction analysis and sequencing. HFK2 and HFK3 were found to be closely related but different from HFK1. Therefore, it would appear that HFK1, HFK2, HFK3, and BF-1 form a new fork head related subfamily. 33 refs., 6 figs.« less

A novel fibroblast growth factor receptor family member promotes neuronal outgrowth and synaptic plasticity in aplysia.

Fibroblast Growth Factor (FGF) Receptors (FGFRs) regulate essential biological processes, including embryogenesis, angiogenesis, cellular growth and memory-related long-term synaptic plasticity. Whereas canonical FGFRs depend exclusively on extracellular Immunoglobulin (Ig)-like domains for ligand binding, other receptor types, including members of the tropomyosin-receptor-kinase (Trk) family, use either Ig-like or Leucine-Rich Repeat (LRR) motifs, or both. Little is known, however, about the evolutionary events leading to the differential incorporation of LRR domains into Ig-containing tyrosine kinase receptors. Moreover, although FGFRs have been identified in many vertebrate species, few reports describe their existence in invertebrates. Information about the biological relevance of invertebrate FGFRs and evolutionary divergences between them and their vertebrate counterparts is therefore limited. Here, we characterized ApLRRTK, a neuronal cell-surface protein recently identified in Aplysia. We unveiled ApLRRTK as the first member of the FGFRs family deprived of Ig-like domains that instead contains extracellular LRR domains. We describe that ApLRRTK exhibits properties typical of canonical vertebrate FGFRs, including promotion of FGF activity, enhancement of neuritic outgrowth and signaling via MAPK and the transcription factor CREB. ApLRRTK also enhanced the synaptic efficiency of neurons known to mediate in vivo memory-related defensive behaviors. These data reveal a novel molecular regulator of neuronal function in invertebrates, provide the first evolutionary linkage between LRR proteins and FGFRs and unveil an unprecedented mechanism of FGFR gene diversification in primeval central nervous systems.

We aimed to compare the influence of various parental factors on adolescent suicidal ideas from a population-based sample of 2965 adolescents between 15 to 18 years-old, and their parents. Among the subject variables, gender, satisfaction with one's health, having an illness, and satisfaction with family; and among parental variables, fathers' satisfaction with health; mothers' insufficient sleep; parents' history of suicidal ideation, and satisfaction with family were significantly different in adolescents who reported suicidal ideation compared to those who reported none. Odds ratios indicated increased risk of adolescent suicidal ideation was associated with the subject factors female gender, insufficient sleep, dissatisfaction with one's health, dissatisfaction with family, and with maternal data showing insufficient sleep and a positive history of suicidal impulse. A path analysis model (comparative fit index (CFI)=0.907; root mean square error of approximation (RMSEA)=0.047), indicated psychosocial factors (beta=0.232) had a greater influence on adolescent suicidal ideation than did genetic factors (beta=0.120). These results show psychosocial factors have an almost two-fold greater influence on adolescent suicidal ideation than genetic factors. Assessment and modification of these factors would greatly assist future interventions. Copyright 2010 Elsevier Ireland Ltd. All rights reserved.

The relationship between lifestyle factors, past medical conditions, daily meal frequency, diet and the risk of 'familial' colorectal cancer has been analysed using data from a case-control study conducted in northern Italy. A total of 1584 colorectal cancer patients and 2879 control subjects were admitted to a network of hospitals in the Greater Milan area and the Pordenone province. The subjects included for analysis were the 112 cases and the 108 control subjects who reported a family history of colorectal cancer in first-degree relatives. Colorectal cancer cases and control subjects with family history were similarly distributed according to sex, age, marital status, years of schooling and social class. Familial colorectal cancer was associated with meal frequency, medical history of diabetes (relative risk, RR = 4.6) and cholelithiasis (RR = 5.2). Significant positive trends of increasing risk with more frequent consumption were observed for pasta (RR = 2.5, for the highest vs the lowest intake tertile), pastries (RR = 2.4), red meat (RR = 2.9), canned meat (RR = 1.9), cheese (RR = 3.5) and butter (RR = 1.9). Significant inverse associations and trends in risk were observed for consumption of poultry (RR = 0.4), tomatoes (RR = 0.2), peppers (RR = 0.3) and lettuce (RR = 0.3). Significant inverse trends in risk with increasing consumption for beta-carotene and ascorbic acid were observed (RR = 0.5 and 0.4 respectively, highest vs lowest intake tertile). These results suggest that risk factors for subjects with a family history of colorectal cancer in first-degree relatives are not appreciably different from recognized risk factors of the disease in the general population.

Analyses concerning peer violence among girls and boys aged 13-17 years, in the context of socio- -economic characteristics of the family: family structure, parental employment status and perceived family wealth. Preliminary data from the recent HBSC studies conducted in 12 voivodeships in Poland in 2013 was used. The analyzes concerned 2300 students aged 13-17 years (45% boys) and focused on the following types of violence: being a perpetrator and a victim of bullying, participation in fights and cyberbullying. Chi-square test analysis and multivariate logistic regression models were used. Significantly more boys than girls experienced bullying (28% vs. 22%) and was perpetrators of violence in the school (39% vs. 25%). The youth from single-parent families significantly more often than students from two-parent families, participated in fights and was the perpetrators of violence in the school. Being a perpetrator and a victim of violence concerned mostly students from poor families and boys, whose father was unemployed. The following risk factors was identified- among boys: low economic status of the family (victims of bullying) and single-parent family (victims of cyberbullying), father's unemployment (the perpetrator of bullying) and age 13-14 years (victims and perpetrators of bullying, participation in fights) and among girls: low economic status of the family (cyberbullying), mother's unemployment and age 13-14 years (victims of violence). The family socio-economic factors, gender and age determine the type and the prevalence of peer violence. Low economic status of the family and single-parent family increases the risk of experiencing violence. For the prevention of bullying the educational role of the father and his commitment to family budget are important.

Children in planned lesbian families: stigmatisation, psychological adjustment and protective factors.

The study assessed the extent to which children between eight and 12 years old in planned lesbian families in the Netherlands experience stigmatization, as well as the influence of protective factors (relationship with parents, social acceptance by peers, contact with children from other families headed by lesbian mothers or gay fathers) on their psychological adjustment (conduct problems, emotional symptoms, hyperactivity, self-esteem). Data were collected by questionnaires filled out by the mothers and by the children themselves. The children in the sample generally reported low levels of stigmatization. However, boys more often reported that, in their view, they were excluded by peers because of their non-traditional family situation. Girls more often reported that other children gossiped about the fact that they had two lesbian mothers. Higher levels of stigmatization were associated with more hyperactivity for boys and lower self-esteem for girls. Having frequent contact with other children who have a lesbian mother or gay father protects against the negative influence of stigmatization on self-esteem. Findings support the idea that children in planned lesbian families benefit from the experience of meeting other children from similar families.

The leucine zipper (bZIP) transcription factors play important roles in multiple biological processes. However, less information is available regarding the bZIP family in the important fruit crop banana. In this study, 121 bZIP transcription factor genes were identified in the banana genome. Phylogenetic analysis showed that MabZIPs were classified into 11 subfamilies. The majority of MabZIP genes in the same subfamily shared similar gene structures and conserved motifs. The comprehensive transcriptome analysis of two banana genotypes revealed the differential expression patterns of MabZIP genes in different organs, in various stages of fruit development and ripening, and in responses to abiotic stresses, including drought, cold, and salt. Interaction networks and co-expression assays showed that group A MabZIP-mediated networks participated in various stress signaling, which was strongly activated in Musa ABB Pisang Awak. This study provided new insights into the complicated transcriptional control of MabZIP genes and provided robust tissue-specific, development-dependent, and abiotic stress-responsive candidate MabZIP genes for potential applications in the genetic improvement of banana cultivars.

Family factors and emotional functioning can play an important role in the ability of adolescents with juvenile primary fibromyalgia syndrome (JPFS) to cope with their condition and function in their everyday lives. The primary objectives of this study were to determine 1) whether adolescents with JPFS and their caregivers differed from healthy age-matched comparison peers and their caregivers in terms of emotional distress and functional impairment; 2) whether there were any differences in the family environment of adolescents with JPFS compared with healthy comparison peers; and 3) which individual-, caregiver-, and family-level variables were associated with functional impairment in adolescents with JPFS. Participants were 47 adolescents with JPFS recruited from a pediatric rheumatology clinic and 46 comparison peers without chronic illness matched for age, sex, and race. Participants and their caregivers (all mothers) completed a battery of standardized measures administered in their homes. Adolescents with JPFS had greater internalizing and externalizing symptoms than healthy comparison peers. Mothers of adolescents with JPFS reported twice as many pain conditions and significantly greater depressive symptoms than mothers of comparison peers. The JPFS group also had poorer overall family functioning and more conflicted family relationships. In adolescents with JPFS, maternal pain history was associated with significantly higher functional impairment. Increased distress and chronic pain are evident in families of adolescents with JPFS, and family relationships are also impacted. Implications for child functional impairment and the need for inclusion of caregivers in treatment are discussed.

2004-04-01

The objective of this study was the risk factors of wife assault in Hong Kong Chinese families. The sample included 107 battered women from a refuge for battered women. Factor analysis revealed risk factors like dominance, stress, poor anger management, aggressive personality, conflict, lack of empathy, masculine gender role stress, sense of insecurity, relationship distress, and violent socialization. Correlation analysis indicated that dominance, spousal conflict, and sense of insecurity increase the likelihood of carrying out minor physical assault and using psychological aggression, while aggressive personality predicts severe physical assault and injury. The risk factors were explained in terms of traditional Chinese concepts of gender role expectations of men and women and face orientations. The present study provides some evidence relating to the risk factors of wife assault in Chinese families.

Factors affecting the cultural competence of visiting nurses for rural multicultural family support in South Korea.

With the recent growth of multicultural families in the Korean society, the importance of the role of qualified visiting nurses in the delivery of culturally sensitive health care has grown dramatically. As the primary health care provider for multicultural families enrolled in public community-based health care centers, the cultural competence of visiting nurses is an essential qualification for the provision of quality health care for multicultural families, especially in rural areas. Cultural competence of visiting nurses is based on their cultural awareness and empathetic attitude toward multicultural families. This study aimed to examine the levels of cultural competence, empowerment, and empathy in visiting nurses, and to verify the factors that affect the cultural competence of visiting nurses working with rural multicultural families in South Korea. Employing a cross-sectional descriptive study design, data from 143 visiting nurses working in rural areas were obtained. Data collection took place between November 2011 and August 2012. The measurement tools included the modified Korean version of the Cultural Awareness Scale, the Text of Items Measuring Empowerment, and the Interpersonal Reactivity Index to measure the level of empathy of visiting nurses. Analyses included descriptive statistics, a t-test, an ANOVA, a Pearson correlation coefficient analysis, and a multiple linear regression analysis. The cultural competence score of the visiting nurses was 3.07 on a 5-point Likert scale (SD = 0.30). The multiple regression analysis revealed that the cultural competence of visiting nurses was significantly influenced by experience of cultural education, empathy, and scores on the meaning subscale of the empowerment tool (R 2  = 10.2%). Institutional support to enhance visiting nurses' empowerment by assuring the significance of their job and specific strategies to enhance their empathy would be helpful to improve the cultural competence of visiting

MAOA promoter methylation and susceptibility to carotid atherosclerosis: role of familial factors in a monozygotic twin sample

PubMed Central

2012-01-01

Background Atherosclerosis is a complex process involving both genetic and epigenetic factors. The monoamine oxidase A (MAOA) gene regulates the metabolism of key neurotransmitters and has been associated with cardiovascular risk factors. This study investigates whether MAOA promoter methylation is associated with atherosclerosis, and whether this association is confounded by familial factors in a monozygotic (MZ) twin sample. Methods We studied 84 monozygotic (MZ) twin pairs drawn from the Vietnam Era Twin Registry. Carotid intima-media thickness (IMT) was measured by ultrasound. DNA methylation in the MAOA promoter region was quantified by bisulfite pyrosequencing using genomic DNA isolated from peripheral blood leukocytes. The association between DNA methylation and IMT was first examined by generalized estimating equation, followed by matched pair analyses to determine whether the association was confounded by familial factors. Results When twins were analyzed as individuals, increased methylation level was associated with decreased IMT at four of the seven studied CpG sites. However, this association substantially reduced in the matched pair analyses. Further adjustment for MAOA genotype also considerably attenuated this association. Conclusions The association between MAOA promoter methylation and carotid IMT is largely explained by familial factors shared by the twins. Because twins reared together share early life experience, which may leave a long-lasting epigenetic mark, aberrant MAOA methylation may represent an early biomarker for unhealthy familial environment. Clarification of familial factors associated with DNA methylation and early atherosclerosis will provide important information to uncover clinical correlates of disease. PMID:23116433

2016-04-01

Residency program selection is a significant experience for emerging physicians, yet there is limited information about how applicants narrow their list of potential programs. This study examines factors that influence residency program selection among medical students interested in family medicine at the time of application. Medical students with an expressed interest in family medicine were invited to participate in a 37-item, online survey. Students were asked to rate factors that may impact residency selection on a 6-point Likert scale in addition to three open-ended qualitative questions. Mean values were calculated for each survey item and were used to determine a rank order for selection criteria. Logistic regression analysis was performed to identify factors that predict a strong interest in urban, suburban, and rural residency programs. Logistic regression was also used to identify factors that predict a strong interest in academic health center-based residencies, community-based residencies, and community-based residencies with an academic affiliation. A total of 705 medical students from 32 states across the country completed the survey. Location, work/life balance, and program structure (curriculum, schedule) were rated the most important factors for residency selection. Logistic regression analysis was used to refine our understanding of how each factor relates to specific types of residencies. These findings have implications for how to best advise students in selecting a residency, as well as marketing residencies to the right candidates. Refining the recruitment process will ensure a better fit between applicants and potential programs. Limited recruitment resources may be better utilized by focusing on targeted dissemination strategies.

Shared vision promotes family firm performance.

Neff, John E

2015-01-01

A clear picture of the influential drivers of private family firm performance has proven to be an elusive target. The unique characteristics of private family owned firms necessitate a broader, non-financial approach to reveal firm performance drivers. This research study sought to specify and evaluate the themes that distinguish successful family firms from less successful family firms. In addition, this study explored the possibility that these themes collectively form an effective organizational culture that improves longer-term firm performance. At an organizational level of analysis, research findings identified four significant variables: Shared Vision (PNS), Role Clarity (RCL), Confidence in Management (CON), and Professional Networking (OLN) that positively impacted family firm financial performance. Shared Vision exhibited the strongest positive influence among the significant factors. In addition, Family Functionality (APGAR), the functional integrity of the family itself, exhibited a significant supporting role. Taken together, the variables collectively represent an effective family business culture (EFBC) that positively impacted the long-term financial sustainability of family owned firms. The index of effective family business culture also exhibited potential as a predictive non-financial model of family firm performance.

Type 1 diabetes mellitus is the most common chronic endocrine disease in children, with a very low incidence in the first months of life and reaching its peak during puberty (10-15 years old is the age group with the highest incidence at the time of onset). Based on the review of the scientific literature, our objective is to study the main psychosocial factors associated with the adjustment of these pediatric patients and their families. Research underscore the following risk factors: situational (stressful life events), personal (additional physical diseases, low self-esteem, emotional disturbances), and interpersonal (family breakdown and conflicts), and also protection factors (coping strategies, social support, fluent communication). There is a pressing need to deal with the disturbances that affect these diabetic patients and their families, by implementing effective health care psychological interventions that take into account psychosocial factors associated with the course of type 1 diabetes mellitus.

Melamine is a new risk of urinary stones. Gansu province is a heavily affected area and has large population and underdeveloped economy. We hypothesized that number of family members and family income may play significant roles in the formation of urinary stones. A case-control study was performed among 190 infants. Results showed that the case group had less numbers of family members than the control (4.4 vs. 5.6, respectively). The multivariate logistic regression analysis indicated that number of family members was an independent influencing factor associated with urinary stones (OR, 0.606; 95% CI, 0.411–0.893; P = 0.011). Family income, however, did not exhibit a significant difference. Observed results suggested that number of family members was a new and significant influencing factor to affect the risk of melamine-associated urinary stones. PMID:23967433

The study assessed the association of family environment factors with adolescents' participation in organized leisure-time activities (OLTA). We used data on 10,472 Czech adolescents aged 11-15 years (49.2% boys) from the 2013/2014 Health Behaviour in School-aged Children study. The associations of family support, the presence of parental screen-time rules and joint family activities with participation in at least one OLTA were assessed using logistic regression. High family support and the presence of parental screen-time rules were associated with higher odds of OLTA participation. Moreover, adolescents playing sports, indoor games and going for walks with their families at least weekly were more likely to participate in OLTA. Conversely, those spending time in joint family TV/video watching on most days were less likely to do so. A supportive family environment and direct parental involvement in their adolescent children's leisure are associated with OLTA participation in early to middle adolescence.

Weinstein, A G

1987-10-01

Crying behavior of the asthmatic child may induce wheezing symptoms. This may be a clinical problem for families with asthmatic children who exhibit frequent and persistent crying behavior. This case report identifies behaviors by the child and parents that may be responsible for continual crying. Child factors include (1) "spoiled" personality, (2) poor self-image, (3) biologic sensitivity to foods, medication, and environmental allergens producing irritability. Parental factors include poor disciplinary practices secondary to (1) disrupted home life, (2) guilt, and (3) overprotective behavior. Identification of these factors may be helpful in establishing clinical management strategies to reduce crying-induced asthma.

The incidence of single-parent families has increased significantly in Taiwan in recent years. Children born in single-parent families are predisposed to suffering from emotional problems. We aimed to determine if the children of single-parent families are more depressive than children from both-parent families, and to examine the individual and joint effects of various factors on the depression risk. A cross-sectional study was performed to investigate the depression status of elementary school children in MiaoLi County, Taiwan. A total of 881 eligible subjects, including 144 children from single-parent families were recruited from 29 schools. Data for depression-related demographic characteristics, family and school variables were collected. The results show that 27.6% of children from single-father families with depressive symptoms, 15.1% children from single-mother families and 15.3% children from both-parent families with repressive symptoms. This study provides significant evidences that single-father family was one significant predictor for childhood depression and the enhanced effects of socioeconomic status and peer relationship on depression of children from single father families were found up to 4-fold (OR=4.0, 95% CI=1.8-8.5) and 5-fold (OR=5.5, 95% CI=2.3-13.2) risk respectively. The results provide hints to parents and teachers for improving the mental health of children in single-parent families by reducing the occurrence of depression. Copyright © 2013 Elsevier Ltd.

2002-09-27

Mutations in two genes, alpha-synuclein and parkin, have been identified as some rare causes for familial Parkinson's disease (PD). alpha-Synuclein and parkin protein have subsequently been identified in Lewy bodies (LB). To gain further insight into the pathogenesis of PD we investigated the role of neurofilament light (NF-L), another component of LB aggregation. A detailed mutation search of the NF-L gene in 328 sporadic and familial PD patients of German ancestry revealed three silent DNA changes (G163A, C224T, C487T) in three unrelated patients. Analysis of the promoter region of the NF-L gene identified a total of three base pair substitutions defining five haplotypes. Association studies based on these haplotypes revealed no significant differences between PD patients and 344 control individuals. Therefore, NF-L is unlikely to play a major role in the pathogenesis of PD.

The purposes of this study were to explore the effects of family cohesion and subjective happiness on death anxiety of Korean elders and to identify other factors contributing to death anxiety. The participants were 280 elders who lived in P metropolitan city. Data were collected between November 5, 2011 and January 12, 2012 using the Short Portable Mental Status Questionnaire (SPMSQ), Family Cohesion Evaluation Scale, Subjective Happiness Scale, and Fear of Death Scale (FODS). Data were analyzed using the SPSS/WIN 19.0 program. Family cohesion, marital status, religious activity, perceived health status, and subjective happiness were included in the factors affecting death anxiety of Korean elders. These variables explained 50.1% of death anxiety. The results of the study indicate that these variables should be considered in developing nursing intervention programs to decrease death anxiety and increase family cohesion and subjective happiness for life integration in Korean elders.

Family demands, social support and family functioning in Taiwanese families rearing children with Down syndrome.

Down syndrome (DS) affects not only children but also their families. Much remains to be learned about factors that influence how families of children with DS function, especially families in non-Western populations. The purpose of this cross-sectional, correlational study was to examine how family demographics, family demands and social support relate to family functioning as well as the potential mediating effect of social support on the relationship between family demands and family functioning in Taiwanese families of children with DS. One hundred and fifty-five parents (80 mothers and 75 fathers) from 83 families independently completed mailed questionnaires. Data were analysed using a principal component analysis and mixed linear modelling. Families having older children with DS, greater parental education, higher family income, fewer family demands and greater social support contributed to healthier family functioning. Social support partially mediated the effects of family demands on family functioning. Family demographics, family demands and social support appear to be important factors that may play a critical role in how Taiwanese families respond to the birth of a child with DS. Care of children with DS and their families is likely to be more effective if professionals working with these families are aware of factors that contribute to healthy family functioning. © 2013 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

The present study examined the relative predictive value of parental anxiety, parents' expectation of child threat bias, and family dysfunction on child's threat bias in a clinical sample of anxious youth. Participants (N = 488) were part of the Child/Adolescent Anxiety Multi-modal study (CAMS), ages 7–17 years (M = 10.69; SD = 2.80). Children met diagnostic criteria for generalized anxiety disorder, separation anxiety and/or social phobia. Children and caregivers completed questionnaires assessing child threat bias, child anxiety, parent anxiety and family functioning. Child age, child anxiety, parental anxiety, parents' expectation of child's threat bias and child-reported family dysfunction were significantly associated with child threat bias. Controlling for child's age and anxiety, regression analyses indicated that parents' expectation of child's threat bias and child-reported family dysfunction were significant positive predictors of child's self-reported threat bias. Findings build on previous literature by clarifying parent and family factors that appear to play a role in the development or maintenance of threat bias and may inform etiological models of child anxiety.

CFSC (Community and Family Study Center) study finds birth rates falling everywhere - family planning (family planning) is a factor.

PubMed

1978-08-01

The findings of the Community and Family Study Center study, based on estimated crude birthrates and total fertility rates for 1968 and 1975, indicate that there has been a significant reduction in fertility levels of both developed and developing countries. Despite regional variations, the estimates show an average proportional decline of 8.5% in total fertility rates between 1968 and 1975. Of the 148 nations studied, 113 were in developing regions and 35 in the developed regions. Information on important social and economic development factors, such as life expectancy, literacy, percent of labor force in agriculture, per capita income, and family planning program strength were gathered for each country. Analyses of these data are reported in "The Public Interest" (to be published) "Population Reference Bulletin," October 1978, and a paper presented at the 1978 Population Association of America Meetings in Atlanta, Georgia. The recent change in fertility affected 81% of the world's population, primarily the peoples of Asia, Latin America, and North America. The total fertility rate in the world in 1968 was 4635 and declined to 4068 in 1975. More substantial declines occurred in Asia and Latin America, where the number of fewer births 1000 women would bear under a given fertility schedule declined by 845 births and 617 births, respectively. As more research is conducted to investigate the underlying causes of this decline, it is likely to confirm the important role that family planning programs have had in developing nations. Although major improvements in the socioeconomic well-being of the developing areas continue as an essential goal, the need to maintain the organized provision of family planning services should not be understated.

Snakes are a diverse and important group of vertebrates. However, relationships among the major groups of snakes have remained highly uncertain, with recent studies hypothesizing very different (and typically weakly supported) relationships. Here, we address family-level snake relationships with new phylogenomic data from 3776 nuclear loci from ultraconserved elements (1.40million aligned base pairs, 52% missing data overall) sampled from 29 snake species that together represent almost all families, a dataset ∼100 times larger than used in previous studies. We found relatively strong support from species-tree analyses (NJst) for most relationships, including three largely novel clades: (1) a clade uniting the boas, pythons and their relatives, (2) a clade placing cylindrophiids and uropeltids with this clade, and (3) a clade uniting bolyeriids (Round Island boas) with pythonids and their relatives (xenopeltids and loxocemids). Relationships among families of advanced snakes (caenophidians) were also strongly supported. The results show the potential for phylogenomic analyses to resolve difficult groups, but also show a surprising sensitivity of the analyses to the inclusion or exclusion of outgroups.

OBJECTIVE: To determine the strength of the association between antenatal psychosocial risk factors and adverse postpartum outcomes in the family, such as assault of women by their partner, child abuse, postpartum depression, marital dysfunction and physical illness. DATA SOURCES: MEDLINE, Cinahl, Famli, Psych Abstracts and the Oxford Database of Perinatal Trials were searched from relevant articles published from Jan. 1, 1980, to Dec. 31, 1993, with the use of MeSH terms "depression, involutional," "child abuse," "child neglect," "domestic violence," "family," "marital adjustment," "family health," "newborn health," "child health," "physical illness," "social support," "psychosocial risk," "prediction," "risk factors," "obstetrics" and "prenatal care." Further articles were identified from bibliographies. STUDY SELECTION: Of the 370 articles identified through the search, 118 were included for review. Studies were included if they examined the association between psychosocial risk factors and the outcomes of interest. Articles were excluded if they were reviews of poor quality or they had one or more of the following features: insufficient description of the sample, a high attrition rate, a lack of standardized outcome measures, outcomes other than the ones of interest or results that had already been reported in a previous study. DATA EXTRACTION: The strength of evidence of each study was evaluated. On the basis of the evidence, each risk factor was assigned a rating of the strength of its association with each of the postpartum outcomes. The ratings were class A (good evidence of association), class B (fair evidence) and class C (no clear evidence). Of the 129 antenatal psychosocial risk factors studied, 15 were found to have a class A association with at least one of the postpartum outcomes. DATA SYNTHESIS: Child abuse and abuse of the mother by her partner were most strongly correlated (class A evidence) with a history of lack of social support, recent life

The aim of this study was to examine whether self-esteem mediates the relationship between family factors and depressive symptoms in young adults. Participants completed self-report questionnaires about overall family environment, conflict with mother or father, parental rearing, self esteem, and depressive symptoms. Self-esteem was found to mediate the relationship between the combined family factors and depressive symptoms. When examined simultaneously, none of the individual family variables uniquely predicted depressive symptoms or self-esteem. However, separate analysis of each of the three family factors provided evidence for self-esteem mediating the relationship between parental conflict and depressive symptoms, and the relationship between parental care and depressive symptoms. Self-esteem may play a role in the mechanism underlying the link between parent-offspring relationship factors and depressive symptoms.

Krüppel Like Factors (KLF) refers to a family of seventeen members of transcription factors. Involved in several cellular processes. As other cancer types, Cervical Cancer (CC) presents molecular deregulations in transcription factors, but especially Human Papilloma Virus (HPV) sequences. Here in this work we analyzed the mRNA expression of all KLF family members in CC-derived cell lines and CC tissues. The cell lines used were HeLa, INBL, RoVa, C4-I, Ms751, ViPa, CaLo, SiHa, CaSki, C33a and ViBo and the non-tumorigenic HaCaT. mRNA expression was analyzed by means of expression microarray and RT-PCR, and KLF5 protein by immunofluorescence. The cell lines were grouped according to HPV genotype as HPV16, HPV18 positive or HPV negative cells. Heterogeneous expression was observed among the cell lines. Despite the heterogeneous expression profile, KLF3, -5, -12, -15 and -16 transcripts were present in all cell lines, KLF4 and -10 which were not expressed in CaSki; KLF11 and 13 were not expressed by Vipa and C4-I, and KLF7 was not expressed by C4-I and Rova. The CC tissue analysis shows expression of most of the KLF members, such as KLF5. KLF5 immunosignal was positive in the three cell lines analyzed. We suggest that KLF expression could not be related to HPV presence/genotype, at least at transcriptional level, and the expression of KLF family members may be necessary in the biology of the CC cells.

Decision making regarding the place of end-of-life (EOL) care is an important issue for patients with terminal cancer and their families. It often requires surrogate decision making, which can be a burden on families. To explore the burden on the family of patients dying from cancer related to the decisions they made about the place of EOL care and investigate the factors affecting this burden. This was a cross-sectional mail survey using a self-administered questionnaire. Participants were 700 bereaved family members of patients with cancer from 133 palliative care units in Japan. The questionnaire covered decisional burdens, depression, grief, and the decision-making process. Participants experienced emotional pressure as the highest burden. Participants with a high decisional burden reported significantly higher scores for depression and grief (both P < 0.001). Multiple regression analyses revealed that higher burden was associated with selecting a place of EOL care that differed from that desired by participants (P < 0.001) and patients (P = 0.034), decision making without knowing the patient's wishes and values (P < 0.001) and without participants sharing their wishes and values with the patient's doctors and/or nurses (P = 0.022), and making the decision because of a due date for discharge from a former facility or hospital (P = 0.005). Decision making regarding the place of EOL care was recalled as burdensome for family decision makers. An early decision-making process that incorporates sharing patients' and family members' values that are relevant to the desired place of EOL care is important.

Purpose This study investigates whether family and peer connections and prosocial norms buffer adolescent girls’ violence involvement, and whether a youth development intervention augments the power of these protective factors in reducing girls’ risk for violence. Methods Data were obtained from 253 13–17 year-olds enrolled in a randomized controlled trial of Prime Time, a youth development intervention offered through urban clinic settings to girls at high risk for pregnancy. Participants completed an A-CASI survey at baseline, 6, 12, and 18 months following enrollment. Protective factors included scales assessing family and peer connections and prosocial norms. Outcome variables were violence victimization and perpetration scales measured at 18 months. Results Family connections and prosocial norms independently protected girls against violence involvement. Peer prosocial norms also served as a protective buffer against violence perpetration and victimization; however, girls with strong peer connections had higher levels of violence perpetration. Participation in Prime Time augmented the protective effects of family and peer connections on girls’ violence victimization but not perpetration. Prime Time participants who had high levels of family connections reported the lowest levels of violence victimization at 18 months. Prime Time participants with strong peer connections trended toward lower levels of violence victimization than other girls. Conclusions Results suggest that effects of the Prime Time intervention on violence victimization were optimized among high-risk adolescent girls with strong connections to family and peers. The intervention was most potent in preventing violence victimization among girls with strong prosocial connections to family and peers. PMID:23299002

Identifying family factors associated with the presence of co-dependency in nurses of a regional hospital in Cancún, Quintana Roo, Mexico. Cross-sectional, comparative study. City of Cancun (México). A random sample of 200nurses who met the inclusion criteria (having a partner for over a year, to be at work on the day of the interview), and who gave informed consent, completed three questionnaires during different shifts. Age, educational level, socioeconomic status, type of family structure, life cycle stage, co-dependency and family functioning. A total of 200nurses, with mean age of 36±8years, took part. The most common socioeconomic status was high (48%), and 47.5% had graduate studies. A co-dependency level of 20.5% (95%CI: 15-26.5) was found. Family factors associated with the presence of co-dependency were; family dysfunction, prevalence ratio (PR)=9.62 (95%CI: 3.47-27.3), stage of independence, PR=3.41 (95%CI: 1.44-7.86), single parent, PR=6.35 (95%CI: 2.41-16.68), and time with partner less than 5 years, PR=3.41 (95%CI: 1.54-7.85). It was found that family dysfunction and being a single parent were significantly associated with co-dependency in hospital nurses, therefore, on being able to identify these factors, family physicians can improve their dynamics and functioning by family study, and improving effective communication with nursing staff and their families.

We used a data-driven Bayesian model to automatically identify distinct latent factors of overlapping atrophy patterns from voxelwise structural MRIs of late-onset Alzheimer's disease (AD) dementia patients. Our approach estimated the extent to which multiple distinct atrophy patterns were expressed within each participant rather than assuming that each participant expressed a single atrophy factor. The model revealed a temporal atrophy factor (medial temporal cortex, hippocampus, and amygdala), a subcortical atrophy factor (striatum, thalamus, and cerebellum), and a cortical atrophy factor (frontal, parietal, lateral temporal, and lateral occipital cortices). To explore the influence of each factor in early AD, atrophy factor compositions were inferred in beta-amyloid-positive (Aβ+) mild cognitively impaired (MCI) and cognitively normal (CN) participants. All three factors were associated with memory decline across the entire clinical spectrum, whereas the cortical factor was associated with executive function decline in Aβ+ MCI participants and AD dementia patients. Direct comparison between factors revealed that the temporal factor showed the strongest association with memory, whereas the cortical factor showed the strongest association with executive function. The subcortical factor was associated with the slowest decline for both memory and executive function compared with temporal and cortical factors. These results suggest that distinct patterns of atrophy influence decline across different cognitive domains. Quantification of this heterogeneity may enable the computation of individual-level predictions relevant for disease monitoring and customized therapies. Factor compositions of participants and code used in this article are publicly available for future research.

This study explores the factors affecting the willingness of dialysis patients' family members to become involved in living and deceased organ donation. We utilize cross sectional data on 350 family members of dialysis patients collected through self-administered survey from June to October 2013. The factors affecting willingness to become deceased and living organ donors among respondents were identified by running logistic regressions. The findings reveal that ethnicity, education and role in family are significant factors explaining will­ingness for living donation, while ethnicity, knowledge of organ donation and donor age drive willingness for deceased donation. We also find that the reasons of respondents being unwilling to donate center on the lack of information and family objections for deceased donation, while being medically unfit, scared of surgery and family objections are the reasons for unwillingness to donate living organs. In light of our findings, educational efforts are suggested to decrease the reluctance to become in­volved in living and deceased donation.

WRKY transcription factors (TFs), one of the ten largest TF families in higher plants, play important roles in regulating plant development and resistance. To date, little is known about the WRKY TF family in Brassica oleracea. Recently, the completed genome sequence of cabbage (B. oleracea var. capitata) allows us to systematically analyze WRKY genes in this species. A total of 148 WRKY genes were characterized and classified into seven subgroups that belong to three major groups. Phylogenetic and synteny analyses revealed that the repertoire of cabbage WRKY genes was derived from a common ancestor shared with Arabidopsis thaliana. The B. oleracea WRKY genes were found to be preferentially retained after the whole-genome triplication (WGT) event in its recent ancestor, suggesting that the WGT event had largely contributed to a rapid expansion of the WRKY gene family in B. oleracea. The analysis of RNA-Seq data from various tissues (i.e., roots, stems, leaves, buds, flowers and siliques) revealed that most of the identified WRKY genes were positively expressed in cabbage, and a large portion of them exhibited patterns of differential and tissue-specific expression, demonstrating that these gene members might play essential roles in plant developmental processes. Comparative analysis of the expression level among duplicated genes showed that gene expression divergence was evidently presented among cabbage WRKY paralogs, indicating functional divergence of these duplicated WRKY genes.

To assess the degree of caregiver burden and family functioning among Taiwanese primary family caregivers of people with schizophrenia and to test its association with demographic characteristics, family demands, sense of coherence and family hardiness. Family caregiving is a great concern in mental illness. Yet, the correlates of caregiver burden and family functioning in primary family caregivers of individuals with schizophrenia still remain unclear. A cross-sectional descriptive study. A convenience sample of 137 primary family caregivers was recruited from two psychiatric outpatient clinics in Taiwan. Measures included a demographic information sheet and the Chinese versions of the Family Stressors Index, Family Strains Index, 13-item Sense of Coherence Scale, 18-item Caregiver Burden Scale, Family Hardiness Index and Family Adaptability, Partnership, Growth, Affection, and Resolve Index. Data analysis included descriptive statistics, Pearson's product-moment correlation coefficients, t-test, one-way analysis of variance and a stepwise multiple linear regression. Female caregivers, additional dependent relatives, increased family demands and decreased sense of coherence significantly increased caregiver burden, whereas siblings as caregivers reported lower degrees of burden than parental caregivers. Family caregivers with lower family demands, increased family hardiness and higher educational level had significantly enhanced family functioning. Sense of coherence was significantly correlated with family hardiness. Our findings highlighted the importance of sense of coherence and family hardiness in individual and family adaptation. Special attention needs to focus on therapeutic interventions that enhance sense of coherence and family hardiness, thereby improving the perception of burden of care and family functioning. Given the nature of family caregiving in schizophrenia, understanding of correlates of caregiver burden and family functioning would help

Arabidopsis thaliana BTB/ POZ-MATH proteins interact with members of the ERF/AP2 transcription factor family.

PubMed

Weber, Henriette; Hellmann, Hanjo

2009-11-01

In Arabidopsis thaliana, the BTB/POZ-MATH (BPM) proteins comprise a small family of six members. They have been described previously to use their broad complex, tram track, bric-a-brac/POX virus and zinc finger (BTB/POZ) domain to assemble with CUL3a and CUL3b and potentially to serve as substrate adaptors to cullin-based E3-ligases in plants. In this article, we show that BPMs can also assemble with members of the ethylene response factor/Apetala2 transcription factor family, and that this is mediated by their meprin and TRAF (tumor necrosis factor receptor-associated factor) homology (MATH) domain. In addition, we provide a detailed description of BPM gene expression patterns in different tissues and on abiotic stress treatments, as well as their subcellular localization. This work connects, for the first time, BPM proteins with ethylene response factor/Apetala2 family members, which is likely to represent a novel regulatory mechanism of transcriptional control.

The aim of the present study was to gain insight into the prevalence of depression and its association with self-esteem, family, peer and school factors in a large-scale representative Taiwanese adolescent population. A total of 12,210 adolescent students were recruited into the present study. Subjects with a score >28 on the Center for Epidemiological Studies' Depression Scale were defined as having significant depression; the Rosenberg Self-Esteem Scale, Adolescent Family and Social Life Questionnaire and Family C-APGAR Index were applied to assess subjects' self-esteem, family, peer and school factors. The association between depression and correlates were examined on t-test and chi(2) test. The significant factors were further included in logistic regression analysis. Among 9586 participants (response rate: 86.3%), the prevalence of depression was 12.3%. The risk factors associated with depression in univariate analysis included female gender, older age, residency in urban areas, lower self-esteem, disruptive parental marriage, low family income, family conflict, poorer family function, less satisfaction with peer relationships, less connectedness to school, and poor academic performance. After adjusting the effects of sex, age and location, only subjects with lower self-esteem, higher family conflict, poorer family function, lower rank and decreased satisfaction in their peer group, and less connectedness to school were prone to depression on logistic regression. The prevalence of depression is high in Taiwanese adolescents, and the multiple factors of family, peer, school and individuals are associated with adolescent depression. The factors identified in the present study may be helpful when designing and implementing preventive intervention programs.

Correlation between familial cancer history and epidermal growth factor receptor mutations in Taiwanese never smokers with non-small cell lung cancer: a case-control study.

Lung cancer is a leading cause of cancer deaths in the world. Cigarette smoking remains a prominent risk factor, but lung cancer incidence has been increasing in never smokers. Genetic abnormalities including epidermal growth factor receptor (EGFR) mutations predominate in never smoking lung cancer patients. Furthermore, familial aggregations of patients with these mutations reflect heritable susceptibility to lung cancer. The correlation between familial cancer history and EGFR mutations in never smokers with lung cancer requires investigation. This was a retrospective case-control study that evaluated the prevalence of EGFR mutations in lung cancer patients with familial cancer history. Never smokers with lung cancer treated at a hospital in Taiwan between April 2012 and May 2014 were evaluated. Inclusion criteria were never smokers with non-small cell lung cancer (NSCLC). Exclusion criteria involved patients without records of familial cancer history or tumor genotype. This study included 246 never smokers with lung cancer. The study population mainly involved never smoking women with a mean age of 60 years, and the predominant tumor histology was adenocarcinoma. Lung cancer patients with familial cancer history had an increased prevalence of EGFR mutations compared to patients without family history [odds ratio (OR): 5.9; 95% confidence interval (CI): 3.3-10.6; P<0.001]. Specifically, 57 out of 85 cancer patients (67%) with familial cancer history had these mutations, while 41 out of 161 patients (25%) without family history harbored mutations. Subgroup analysis also revealed that patients with familial lung cancer history had stronger association with EGFR mutations (OR: 7.5; 95% CI: 3.4-16.3; P<0.001) compared to patients with family history of non-pulmonary cancers (OR: 5.0; 95% CI: 2.5-10.0; P<0.001). The study demonstrated an increased prevalence of EGFR mutations in Taiwanese never smoking lung cancer patients with familial cancer history. Moreover, a

To conduct a systematic review of parent and family factors associated with service use for young people with mental health problems, to inform early intervention efforts aimed at increasing service use by young people. A systematic search of academic databases was performed. Articles were included in the review if they had: a sample of young people aged between 5 and 18 years; service use as the outcome measure; one or more parental or family variables as a predictor; and a comparison group of non-service using young people with mental health problems. In order to focus on factors additional to need, the mental health symptoms of the young person also had to be controlled for. Stouffer's method of combining P-values was used to draw conclusions as to whether or not associations between variables were reliable. Twenty-eight articles were identified investigating 15 parental or family factors, 7 of which were found to be associated with service use for a young person with mental health needs: parental burden, parent problem perception, parent perception of need, parent psychopathology, single-parent household, change in family structure and being from the dominant ethnic group for the United States specifically. Factors not found to be related to service use were: family history of service use, parent-child relationship quality, family functioning, number of children, parent education level, parent employment status, household income and non-urban location of residence. A number of family-related factors were identified that can inform effective interventions aimed at early intervention for mental health problems. Areas requiring further research were also identified. © 2015 Wiley Publishing Asia Pty Ltd.

2015-11-11

The prevalence of problem behaviours among British adolescents has increased in the past decades. Following Erikson's psychosocial developmental theory and Bronfenbrenner's developmental ecological model, it was hypothesized that youth problem behaviour is shaped in part by social environment. The aim of this project was to explore potential protective factors within the social environment of British youth's for the presentation of disruptive behavioural problems. This study used secondary data from the Longitudinal Study of Young People in England, a cohort study of secondary school students. These data were analysed with generalized estimation equations to take the correlation between the longitudinal observations into account. Three models were built. The first model determined the effect of family, school, and extracurricular setting on presentation of disruptive behavioural problems. The second model expanded the first model by assuming extracurricular activities as protective factors that moderated the interaction between family and school factors with disruptive behavioural problems. The third model described the effect of prior disruptive behaviour on current disruptive behaviour. Associations were found between school factors, family factors, involvement in extracurricular activities and presence of disruptive behavioural problems. Results from the second generalized estimating equation (GEE) logistic regression models indicated that extracurricular activities buffered the impact of school and family factors on the presence of disruptive behavioural problems. For instance, participation in sports activities decreased the effect of bullying on psychological distress. Results from the third model indicated that prior acts of disruptive behaviour reinforced current disruptive behaviour. This study supports Erikson's psychosocial developmental theory and Bronfenbrenner's developmental ecological model; social environment did influence the presence of

Virulence factors regulated by quorum sensing (QS) play a critical role in the pathogenesis of an opportunistic human pathogen, Pseudomonas aeruginosa in causing infections to the host. Hence, in the present work, the anti-virulence potential of the medicinal plant extracts and their derived phytochemicals from Myrtaceae family was evaluated against P. aeruginosa. In the preliminary screening of the tested medicinal plant extracts, Syzygium jambos and Syzygium antisepticum demonstrated a maximum inhibition in QS-dependent violacein pigment production by Chromobacterium violaceum DMST 21761. These extracts demonstrated an inhibitory activity over a virulence factor, pyoverdin, production by P. aeruginosa ATCC 27853. Gas chromatography-mass spectrometric (GC-MS) analysis revealed the presence of 23 and 12 phytochemicals from the extracts of S. jambos and S. antisepticum respectively. Three top-ranking phytochemicals, including phytol, ethyl linoleate and methyl linolenate, selected on the basis of docking score in molecular docking studies lowered virulence factors such as pyoverdin production, protease and haemolytic activities of P. aeruginosa to a significant level. In addition, the phytochemicals reduced rhamnolipid production by the organism. The work demonstrated an importance of plant-derived compounds as anti-virulence drugs to conquer P. aeruginosa virulence towards the host. © 2017 APMIS. Published by John Wiley & Sons Ltd.

Background Attention deficit hyperactivity disorder (ADHD) is one of the most common psychiatric disorders, affecting an estimated 5 to 12% of school-aged children worldwide. From 15 to 19 million Chinese children suffer from ADHD. The aim of this study was to investigate the association between family-environmental factors and ADHD in a sample of Chinese children. Methods A pair-matched, case-control study was conducted with 161 ADHD children and 161 non-ADHD children of matching age and sex, all from 5–18 years of age. The ADHD subjects and the normal controls were all evaluated via structured diagnostic interviews. We examined the association between family-environmental factors and ADHD using the conditional multiple logistic regression with backward stepwise selection to predict the associated factors of ADHD. Results Having experienced emotional abuse and being a single child were both significant factors associated with children diagnosed with ADHD. ADHD subjects were more likely to have suffered from emotional abuse (OR = 11.09, 95% CI = 2.15–57.29, P = 0.004) and have been a single child in the family (OR = 6.32, 95% CI = 2.09–19.14, P = 0.001) when compared to normal controls. The results were not modified by other confounding factors. Conclusion Our findings provide evidence that family-environmental factors are associated with ADHD among children in China. These findings, if confirmed by future research, may help to decrease ADHD by increasing the awareness of the effects of childhood emotional abuse. PMID:23209774

To compare overweight and non-overweight youth on a selection of self-reported eating, physical activity, dieting, educational, and emotional variables and identify familial factors that serve as protective forces against unhealthy behaviors and psychosocial difficulties among overweight adolescents. Data were taken from a 1996 cross-sectional school-based survey of 9957 adolescents in grades 7, 9, and 11. Based on self-reported heights and weights, respondents were categorized as "overweight" (body mass index) > or =85th percentile or "non-overweight." Student's t-tests were used to compare the non-overweight and overweight sample on the self-reported health-related behaviors and psychosocial variables. Logistic and linear regressions were used to identify familial factors associated with a reduced risk of engaging in unhealthy behaviors and experiencing psychosocial distress. Overweight adolescents reported engaging in significantly more unhealthy behaviors and experiencing more psychosocial distress than their non-overweight peers. Among the overweight youth, higher levels of reported family connectedness and parental expectations and moderate levels of parental monitoring were associated with the lowest levels of unhealthy behaviors and psychosocial distress. Satisfying and developmentally appropriate parent-adolescent relationships are associated with reduced behavioral and psychosocial risk factors associated with overweight during adolescence.

Family psychosocial characteristics in childhood have been associated with children's development into criminal behaviour and mortality. This study explored these possible relationships and examined alcohol and/or drug use and mental problems as possible mediating factors, highlighting gender-specific patterns. Data from Swedish subjects born in 1953 (n = 14,294) from the Stockholm Birth Cohort study were examined. Several indicators of adverse family factors and individual problems were included in the present study. The information was derived from various data sources, covering different periods. Gender-specific associations with incidence of criminality (1966-1980) and mortality (1981-2009) were analysed using logistic regression. Furthermore, the population attributable fraction (PAF) was calculated for all variables in the fully adjusted models which were positively related to the outcome. Overall incidence of criminality and mortality was (m/f 32.3/6.6) and (m/f 6.1/3.5), respectively. The results showed that all aspects of family psychosocial and individual problems studied were associated with criminality for both genders. Among males, individual problems seemed to partly mediate these relations, but the associations remained statistically significant. Interestingly, the PAF analysis revealed a reduction in criminality of 17.5% when individual problems with alcohol and/or drug use were considered. Among females, a significant impact of alcohol and/or drug use on the association between family psychosocial characteristics and subsequent criminality was obtained. Inclusion of father's occupational class only somewhat reduced the estimates for the genders. Concerning male mortality, father's alcohol abuse was significantly related to an increased risk. When individual criminality was accounted for, the association was substantially reduced but remained statistically significant.

Introduction: Every family physician has a key role in achieving the goals of the family physician program (FPP). Low satisfaction of physicians in certain areas of Iran and their low maintenance level in the program is quite challenging. The aims of the present study were; (1) to assess the attitude of rural/rural-urban family physicians about FPP and (2) to investigate their interest toward participation in urban FPP and (3) to explore the influencing factors. Methods: This cross-sectional study was performed on 137 family physicians who were working in rural/rural-urban FPP in Mashhad University of Medical Sciences (Iran). A self-designed valid and reliable questionnaire including demographic data and thirty questions on the participants’ attitudes toward the FPP in Likert scale were used. Data were analyzed by multiple logistic regression models using SPSS software. Results: 49.3% of physicians were interested in continuing their cooperation in the urban-FPP. The mean total attitude score was 62.18 out of 100. The highest agreement and positive attitude of physicians were related to achievements of the program goals dimension. Multiple analyses showed that gender (odds ratio [OR] =5.5; male vs. female) and employment status (OR = 16.7 and 10.9 for permanent employment and by contract compared to legal obligation, respectively) were significantly associated with physicians’ willingness toward participation in the urban-FPP. Conclusion: About half of the studied physicians were interested toward participation in the urban-FPP; Male physicians more than females and permanent employees more than others were willing and interested to participate in the urban-FPP.

Previous microarray analyses of RNAs from 8-cell (8C) human embryos revealed a lack of cell cycle checkpoints and overexpression of core circadian oscillators and cell cycle drivers relative to pluripotent human stem cells [human embryonic stem cells/induced pluripotent stem (hES/iPS)] and fibroblasts, suggesting growth factor independence during early cleavage stages. To explore this possibility, we queried our combined microarray database for expression of 487 growth factors and receptors. Fifty-one gene elements were overdetected on the 8C arrays relative to hES/iPS cells, including 14 detected at least 80-fold higher, which annotated to multiple pathways: six cytokine family (CSF1R, IL2RG, IL3RA, IL4, IL17B, IL23R), four transforming growth factor beta (TGFB) family (BMP6, BMP15, GDF9, ENG), one fibroblast growth factor (FGF) family [FGF14(FH4)], one epidermal growth factor member (GAB1), plus CD36, and CLEC10A. 8C-specific gene elements were enriched (73%) for reported circadian-controlled genes in mouse tissues. High-level detection of CSF1R, ENG, IL23R, and IL3RA specifically on the 8C arrays suggests the embryo plays an active role in blocking immune rejection and is poised for trophectoderm development; robust detection of NRG1, GAB1, -2, GRB7, and FGF14(FHF4) indicates novel roles in early development in addition to their known roles in later development. Forty-four gene elements were underdetected on the 8C arrays, including 11 at least 80-fold under the pluripotent cells: two cytokines (IFITM1, TNFRSF8), five TGFBs (BMP7, LEFTY1, LEFTY2, TDGF1, TDGF3), two FGFs (FGF2, FGF receptor 1), plus ING5, and WNT6. The microarray detection patterns suggest that hES/iPS cells exhibit suppressed circadian competence, underexpression of early differentiation markers, and more robust expression of generic pluripotency genes, in keeping with an artificial state of continual uncommitted cell division. In contrast, gene expression patterns of the 8C embryo suggest that

This study investigates whether family and peer connections and prosocial norms buffer adolescent girls' violence involvement and whether a youth development intervention augments the power of these protective factors in reducing girls' risk for violence. Data were obtained from 253 13-17-year-olds enrolled in a randomized controlled trial of Prime Time, a youth development intervention offered through urban clinic settings to girls at high risk for pregnancy. Participants completed an audio computer-assisted self-interview survey at baseline and 6, 12, and 18 months after enrollment. Protective factors included scales assessing family and peer connections and prosocial norms. Outcome variables were violence victimization and perpetration scales measured at 18 months. Family connections and prosocial norms independently protected girls against violence involvement. Peer prosocial norms also served as a protective buffer against violence perpetration and victimization; however, girls with strong peer connections had higher levels of violence perpetration. Participation in Prime Time augmented the protective effects of family and peer connections on girls' violence victimization but not perpetration. Prime Time participants who had high levels of family connections reported the lowest levels of violence victimization at 18 months. Prime Time participants with strong peer connections trended toward lower levels of violence victimization than other girls. Results suggest that effects of the Prime Time intervention on violence victimization were optimized among high-risk adolescent girls with strong connections to family and peers. The intervention was most potent in preventing violence victimization among girls with strong prosocial connections to family and peers. Copyright © 2013 Society for Adolescent Health and Medicine.

Despite recent developments in post-graduate family medicine training in Japan, the numbers of junior doctors entering family medicine residencies are still limited. The objective of this qualitative study was to investigate the possible factors associated to the career choice of family medicine, especially in the context of the newly established family medicine programs in Japan. From December 2010 to January 2011, we distributed a semi-structured questionnaire about career choice to 58 physician members of the Japan Primary Care Association, and 41 of them responded. Four researchers used the Modified Grounded Theory Approach (Kinoshita, 2003) for three-stage conceptualization. We extracted a conceptual model of the choice of newly established family medicine as a career in Japan, consisting of six categories and 77 subordinate concepts from 330 variations. The subcategories of personal background affecting the family-medicine career choice were characteristics ("self-reliance," "pioneering spirit"), career direction ("community/rural-orientedness," "multifaceted orientation") and experience (e.g., "discomfort with fragmented care"). We divided the influencing factors that were identified for career choice into supporters (e.g., "role model"), conflict of career choice (e.g., "anxiety about diverse/broad practice"), and the dawn of a new era in family medicine in Japan (e.g., "lack of social recognition," "concern about livelihood," and "too few role models"). Although the dawn of a new era seemed a rather negative influencer, it was unique to our study that the dawn itself could attract those with a "pioneering spirit" and an "attitude of self-training." Unlike previous studies, the positive factors such as lifestyle and the short residency program were not shown to be part of family medicine's attractiveness. In contrast, "concern about livelihood" was specific among our respondents and was related to career choice in the dawn period. "Community

20 new items were developed to measure six concepts of family strengths and were administered, along with the Kansas Marital Satisfaction Scale, to over 266 married subjects as part of a larger survey of current and former members of the Christian Church (Disciples of Christ). A common factor analysis suggested that most of the items were associated with their expected factors, while reliability analyses indicated that most of the scales had acceptable estimates of internal consistency. The marital satisfaction items clearly were associated with their own factor and not other factors, providing support for the unidimensional nature of the Kansas Marital Satisfaction Scale and for its construct validity.

Reactivity to uncertain threat as a familial vulnerability factor for alcohol use disorder.

When sober, problematic drinkers display exaggerated reactivity to threats that are uncertain (U-threat). Since this aversive affective state can be alleviated via acute alcohol intoxication, it has been posited that individuals who exhibit heightened reactivity to U-threat at baseline are motivated to use alcohol as a means of avoidance-based coping, setting the stage for excessive drinking. To date, however, no study has attempted to characterize the dispositional nature of exaggerated reactivity to U-threat and test whether it is a vulnerability factor or exclusively a disease marker of problematic alcohol use. The current investigation utilized a family study design to address these gaps by examining whether (1) reactivity to U-threat is associated with risk for problematic alcohol use, defined by family history of alcohol use disorder (AUD) and (2) reactivity to U-threat is correlated amongst adult biological siblings. A total of 157 families, and 458 individuals, participated in the study and two biological siblings completed a threat-of-shock task designed to probe reactivity to U-threat and predictable threat (P-threat). Startle potentiation was collected as an index of aversive responding. Within biological siblings, startle potentiation to U-threat [intraclass correlation (ICC) = 0.35] and P-threat (ICC = 0.63) was significantly correlated. In addition, independent of an individuals' own AUD status, startle potentiation to U-threat, but not P-threat, was positively associated with risk for AUD (i.e. AUD family history). This suggests that heightened reactivity to U-threat may be a familial vulnerability factor for problematic drinking and a novel prevention target for AUD.

This nation-wide register-based study investigated how often anorexia nervosa (AN) and co-morbid disorders occur in affected families compared with control families. Furthermore, the study addressed the impact of sex, year of birth, and degree of urbanization in terms of risk factors. A total of N = 2,370 child and adolescent psychiatric subjects born between 1951 and 1996 and registered in the Danish Psychiatric Central Research Register (DPCRR) had any mental disorder before the age of 18 and developed AN at some point during their life-time. In addition, N = 7,035 controls without any psychiatric diagnosis before age 18 and matched for age, sex, and residential region were included. Psychiatric diagnoses were also obtained on the first-degree relatives as a part of the Danish Three Generation Study (3GS). A family load component was obtained by using various mixed regression models. AN occurred significantly more often in case than in control families. AN Risk factors included having a sibling with AN, affective disorders in family members, and co-morbid affective, anxiety, obsessive-compulsive, personality, or substance use disorders. Furthermore, female sex, and ascending year of birth were significantly associated with having AN. Urbanization was not related to the family load of AN and case-relatives did not develop AN earlier than control relatives. These findings based on a very large and representative dataset provide evidence for the family aggregation and further risk factors in AN. © 2014 Wiley Periodicals, Inc.

Understanding the processes driving speciation in marine ecosystems remained a challenge until recently, due to the unclear nature of dispersal boundaries. However, recent evidence for marine adaptive radiations and ecological speciation, as well as previously undetected patterns of cryptic speciation is overturning this view. Here, we use multi-gene phylogenetics to infer the family-level evolutionary history of Fucaceae (intertidal brown algae of the northern Pacific and Atlantic) in order to investigate recent and unique patterns of radiative speciation in the genus Fucus in the Atlantic, in contrast with the mainly monospecific extant genera. We developed a set of markers from 13 protein coding genes based on polymorphic cDNA from EST libraries, which provided novel resolution allowing estimation of ancestral character states and a detailed reconstruction of the recent radiative history. Phylogenetic reconstructions yielded similar topologies and revealed four independent trans-Arctic colonization events by Fucaceae lineages, two of which also involved transitions from hermaphroditism to dioecy associated with Atlantic invasions. More recently, reversion of dioecious ancestral lineages towards hermaphroditism has occurred in the genus Fucus, particularly coinciding with colonization of more extreme habitats. Novel lineages in the genus Fucus were also revealed in association with southern habitats. These most recent speciation events occurred during the Pleistocene glaciations and coincided with a shift towards selfing mating systems, generally southward shifts in distribution, and invasion of novel habitats. Diversification of the family occurred in the Late-Mid Miocene, with at least four independent trans-Artic lineage crossings coincident with two reproductive mode transitions. The genus Fucus arose in the Pliocene but radiated within a relatively short time frame about 2.5 million years ago. Current species distributions of Fucus suggest that climatic

Family businesses are critical to the United States economy, employing 63% of the workforce and generating 57% of GDP (University of Vermont, 2014). Family business continuity, however, remains elusive as approximately 70% of family businesses do not survive the second generation (Poza, 2013). In order to augment our understanding of how next generation leaders are chosen in family businesses, we examine daughter succession. Using a sample of pairs of family business fathers and daughters and drawing on an earlier study of the dearth of successor daughters in family businesses (Overbeke et al., 2013), we reveal that shared vision between fathers and daughters is central to daughter succession. Self-efficacy and gender norms influence shared vision and when fathers and daughters share a vision for the future of the company, daughters are likely to be transformed into successors.

Family Risk Factors Associated With Aggressive Behavior in Chinese Preschool Children.

Jia, Shoumei; Wang, Ling; Shi, Yingjuan; Li, Ping

The study explored family predictors of aggressive behavior in preschool children in China. Using a stratified cluster sampling method, 1382 preschool children were recruited from ten kindergarten schools in Shanghai, China. Their parents completed the Child Behavior Checklist (CBCL)-aggression subscale, the Parent Behavior Inventory, the Family Environment Scale, and a demographic questionnaire. The mean age of the 1382 children was 4.97years (SD=.88), with 55.1% (762) boys, and 44.9% (620) girls. According to the CBCL, the prevalence of aggressive behavior in preschool children was 12.4%. Multivariate logistic regression analysis showed that family conflicts (OR = 1.231, 95% CI: 1.115-1.360), hostile/coercive parenting (OR = 1.083, 95% CI: 1.051-1.116), inconsistent parenting between grandparents and parents (OR = 1.658, 95% CI: 1.175-2.341), and more time spent watching TV (OR = 1.999, 95% CI: 1.568-2.550) significantly predicted aggressive behavior of children. Children with more family conflicts who experience hostile/coercive parenting were more likely to engage in aggressive behavior. Moreover, inconsistent parenting attitudes between grandparents and parents, and excessive TV exposure also contributed to childhood aggression. Given that the results of this study show a high prevalence of aggressive behavior in preschool children, future research must pay greater attention to this aspect. Family risk factors identified as relevant to children's aggression in this study provide avenues to develop family-focused strategies for curbing aggression in preschool children.

To explore the importance of early life factors shared by siblings, such as parental socioeconomic position, parental practices, housing and neighbourhood, for the association between cardiovascular disease (CVD) risk factors and mortality from CVD, ischaemic heart disease (IHD) and cerebrovascular disease. Norwegian health surveys (1974-2003) were linked with data from the Norwegian Family Based Life Course Study and the Cause of Death Registry. Participants with at least one full sibling among survey participants (n=2 71 643) were included. Data on CVD risk factors, body mass index (BMI), height, systolic blood pressure (SBP) and total cholesterol (TC) were stratified into 'low', 'medium' and 'high' risk, and smoking to 'daily smoking' and 'not daily smoking'. Mean age of participants was 41 years, mean follow-up time was 19 years and during follow-up 2512 died from CVD. For each category of increased risk factor level, the per step HR of CVD mortality was increased by 1.91 (95% CI 1.78 to 2.05) for SBP, 1.67 (1.58 to 1.76) for TC, 1.44 (1.36 to 1.53) for BMI, 1.26 (1.18 to 1.35) for height and 2.89 (2.66 to 3.14) for smoking. In analyses where each sibship (groups of full siblings) had a group-specific baseline hazard, these associations were attenuated to 1.74, 1.51, 1.29, 1.18 and 2.63, respectively. The associations between risk factors and IHD mortality followed the same pattern. Early life family factors explained a small part of the association between risk factors and mortality from CVD and IHD in a relatively young sample.

The consumption of sugar-sweetened beverages (SSB) may contribute to the development of overweight among children. The present study aimed to evaluate associations between family and home-related factors and children's SSB consumption. We explored associations within ethnic background of the child. Cross-sectional data from the population-based 'Water Campaign' study were used. Parents (n = 644) of primary school children (6-13 years) completed a questionnaire on socio-demographic characteristics, family and home-related factors and child's SSB intake. The family and home-related factors under study were: cognitive variables (e.g. parental attitude, subjective norm), environmental variables (e.g. availability of SSB, parenting practices), and habitual variables (e.g. habit strength, taste preference). Regression analyses were used to evaluate the associations between family and home-related factors and child's SSB intake (p < 0.05). Mean age of the children was 9.4 years (SD: 1.8) and 54.1% were girls. The child's average SSB intake was 0.9 litres (SD: 0.6) per day. Child's age, parents' subjective norm, parenting practices, and parental modelling were positively associated with the child's SSB intake. The availability of SSB at home and school and parental attitude were negatively associated with the child's SSB intake. The associations under study differed according to the child's ethnic background, with the explained variance of the full models ranging from 8.7% for children from Moroccan or Turkish ethnic background to 44.4% for children with Dutch ethnic background. Our results provide support for interventions targeting children's SSB intake focussing on the identified family and home-related factors, with active participation of parents. Also, the relationships between these factors and the child's SSB intake differed for children with distinct ethnic backgrounds. Therefore, we would recommend to tailor interventions taking into account the ethnic

The aim of this study was to examine factors that influenced the perceptions of mental health nurses about involving families in their nursing practice. A sample of 175 Taiwanese mental health nurses who are employed in both inpatient and community settings completed structured questionnaires designed to measure empathy, attitudes about involving families in care, and perceptions of family nursing practice. Data were analyzed using descriptive statistics, Pearson's product-moment correlation, t test, one-way ANOVA, and a hierarchical multiple regression analysis. Positive perceptions of family nursing practice were correlated with more years of clinical experience in mental health, empathy, supportive attitudes toward the importance of family nursing care, and personal experiences with family members with serious illness in need of professional care. These findings may assist in the development of effective educational programs designed to help nurses integrate family nursing knowledge and skills in the care of patients and families experiencing mental illness. © The Author(s) 2015.

Functional specialization among insect chitinase family genes revealed by RNA interference

2008-01-01

The biological functions of individual members of the large family of chitinase-like proteins from the red flour beetle, Tribolium castaneum (Tc), were examined by using gene-specific RNAi. One chitinase, TcCHT5, was found to be required for pupal–adult molting only. A lethal phenotype was observed when the transcript level of TcCHT5 was down-regulated by injection of TcCHT5-specific dsRNA into larvae. The larvae had metamorphosed into pupae and then to pharate adults but did not complete adult eclosion. Specific knockdown of transcripts for another chitinase, TcCHT10, which has multiple catalytic domains, prevented embryo hatch, larval molting, pupation, and adult metamorphosis, indicating a vital role for TcCHT10 during each of these processes. A third chitinase-like protein, TcCHT7, was required for abdominal contraction and wing/elytra extension immediately after pupation but was dispensable for larval–larval molting, pupation, and adult eclosion. The wing/elytra abnormalities found in TcCHT7-silenced pupae were also manifest in the ensuing adults. A fourth chitinase-like protein, TcIDGF4, exhibited no chitinolytic activity but contributed to adult eclosion. No phenotypic effects were observed after knockdown of transcripts for several other chitinase-like proteins, including imaginal disk growth factor IDGF2. These data indicate functional specialization among insect chitinase family genes, primarily during the molting process, and provide a biological rationale for the presence of a large assortment of chitinase-like proteins.

The Family Empowerment Scale (FES) was developed specifically to assess empowerment in families with emotional disorders. Its relevance to custodial grandfamilies is reflected in the difficulties in grandchildren's social, emotional, and behavioral functioning, wherein such difficulties may be explained via either reactions to changes in their family structure or in their responses to the newly formed family unit. Utilizing 27 items derived from the 34-item version of the FES, which had represented differential levels of empowerment (family, service system, community) as indexed by one's attitudes, knowledge, and behavior, we explored the factor structure, internal consistency, construct, and convergent validity of the FES with grandparent caregivers. Three-hundred forty-three (M age = 58.45, SD = 8.22, n Caucasian = 152, n African American = 149, n Hispanic = 38) custodial grandmothers caring for grandchildren between ages 4 and 12 years completed the 27 FES items and various measures of their psychological well-being, grandchild psychological difficulties, emotional support, and parenting practices. Factor analysis revealed three factors that differed slightly from the originally proposed FES subscales: Parental Self-Efficacy/Self-Confidence, Service Activism, and Service Knowledge. Each of the factors was internally consistent, and derived factor scores were moderately interrelated, speaking to the question of convergent validity. The construct validity of these three factors was evidenced by meaningful patterns of statistically significant correlations with grandmothers’ psychological well-being, grandchild psychological difficulties, emotional support, and parenting practices. These factor scores were independent of grandmother age, health, and education. These findings suggest the newly identified FES factors to be valuable in understanding empowerment among grandmother caregivers. PMID:26452627

The construct validity of these three factors was evidenced by meaningful patterns of statistically significant correlations with grandmothers' psychological well-being, grandchild psychological difficulties, emotional support, and parenting practices. These factor scores were independent of grandmother age, health, and education. These findings suggest the newly identified FES factors to be valuable in understanding empowerment among grandmother caregivers.

This study aimed to evaluate agreement between children and parents on a measure of behavioral and pharmacological adherence in children with sickle cell disease (SCD), and the associations among family factors (i.e., problem-solving skills, routines, communication) and adherence behaviors. In all, 85 children (aged 8-18 years) with SCD and their parents completed questionnaires assessing individual and family factors. Overall parent-child agreement on an adherence measure was poor, particularly for boys and older children. Greater use of child routines was associated with better overall child-reported adherence. Open family communication was associated with higher overall parent-reported adherence. While further research is needed before definitive conclusions can be drawn, results suggest the need to assess child adherence behaviors via both child and parent reports. Findings also suggest that more daily family routines and open family communication may be protective factors for better disease management. © The Author 2017.

Despite greater risk for poor nutrition, inactivity, and overweight, some low-income children are able to maintain a healthy weight. We explore if a strong family sense of coherence (FSOC) acts as a protective factor against childhood obesity for low-income preschool children. Families with a strong FSOC view challenges as predictable, understandable, worthy of engaging, and surmountable. Data were collected from 321 low-income mothers and their preschool children in five states between March 2011 and May 2013. FSOC was assessed using the Family Sense of Coherence Scale. A 16-item checklist was used to assess practicing healthy child behaviors (fruit and vegetable consumption and availability, physical activity, and family meals) and limiting unhealthy child behaviors (sweetened beverage and fast food consumption, energy dense snack availability, and screen time). Child body mass index (BMI) z-scores were calculated from measured height and weight. FSOC was significantly associated with practicing healthy child behaviors (β = 0.32, p < .001). We did not find a statistically significant association between FSOC and limiting unhealthy child behaviors or child BMI z-scores in fully adjusted models. Our results suggest the importance of family functioning in predicting health behaviors around food consumption and availability, physical activity, and family meals. Copyright © 2016 Elsevier Ltd.

Alcohol oxidases, including carbohydrate oxidases, have a long history of research that has generated fundamental biological understanding and biotechnological applications. Despite a long history of study, the galactose 6-oxidase/glyoxal oxidase family of mononuclear copper-radical oxidases, Auxiliary Activity Family 5 (AA5), is currently represented by only very few characterized members. Here we report the recombinant production and detailed structure–function analyses of two homologues from the phytopathogenic fungi Colletotrichum graminicola and C. gloeosporioides, CgrAlcOx and CglAlcOx, respectively, to explore the wider biocatalytic potential in AA5. EPR spectroscopy and crystallographic analysis confirm a common active-site structure vis-à-vis the archetypal galactose 6-oxidase from Fusarium graminearum. Strikingly, however, CgrAlcOx and CglAlcOx are essentially incapable of oxidizing galactose and galactosides, but instead efficiently catalyse the oxidation of diverse aliphatic alcohols. The results highlight the significant potential of prospecting the evolutionary diversity of AA5 to reveal novel enzyme specificities, thereby informing both biology and applications. PMID:26680532

Objective We assessed the contributions of familial rheumatoid arthritis (RA) or lupus and environmental factors to risk of RA. Methods Among 121,700 women in the Nurses’ Health Study, 65,457 provided data on familial RA/lupus. Among these, 493 RA cases (301 seropositive and 192 seronegative) were validated. We estimated hazard ratios (HR) for RA comparing those with and without familial RA/lupus, adjusting for environmental factors (smoking, alcohol, body mass index [BMI], parity, breastfeeding, menopause, hormone use, early menarche, and menstrual regularity) using Cox proportional hazards models. Population attributable risks (PAR) for RA within this cohort were calculated for familial RA/lupus, smoking, alcohol, BMI, parity, and breastfeeding. Results Familial RA/lupus was significantly associated with RA (HR 3.67), seropositive RA (HR 3.90) and seronegative RA (HR 3.95). After adjusting for environmental factors, familial RA/lupus was significantly associated with RA (HR 3.59, 95% confidence interval 2.94–4.37). Smoking >10 pack-years, alcohol intake 5–10 g/day, overweight, breastfeeding ≥12 months, and pre-menopausal status remained significantly associated with RA after adjusting for familial RA/lupus. For RA in this cohort, the PAR for smoking, BMI, alcohol, parity, or breastfeeding collectively was 41%; the PAR due to heredity from familial RA/lupus was 21%. Conclusion In this large, prospective cohort, women with familial RA/lupus had a four-fold increased risk for RA that remained significant after adjusting for environmental factors. A large proportion of RA risk was attributable to environmental factors even among those with familial RA/lupus. PMID:25103278

Vav family exchange factors: an integrated regulatory and functional view

PubMed Central

Bustelo, Xosé R

2014-01-01

The Vav family is a group of tyrosine phosphorylation-regulated signal transduction molecules hierarchically located downstream of protein tyrosine kinases. The main function of these proteins is to work as guanosine nucleotide exchange factors (GEFs) for members of the Rho GTPase family. In addition, they can exhibit a variety of catalysis-independent roles in specific signaling contexts. Vav proteins play essential signaling roles for both the development and/or effector functions of a large variety of cell lineages, including those belonging to the immune, nervous, and cardiovascular systems. They also contribute to pathological states such as cancer, immune-related dysfunctions, and atherosclerosis. Here, I will provide an integrated view about the evolution, regulation, and effector properties of these signaling molecules. In addition, I will discuss the pros and cons for their potential consideration as therapeutic targets. PMID:25483299

Family function, Parenting Style and Broader Autism Phenotype as Predicting Factors of Psychological Adjustment in Typically Developing Siblings of Children with Autism Spectrum Disorders.

Siblings of children with autism are at a greater risk of experiencing behavioral and social problems. Previous researches had focused on environmental variables such as family history of autism spectrum disorders (ASDs), behavior problems in the child with an ASD, parental mental health problems, stressful life events and "broader autism phenotype" (BAP), while variables like parenting style and family function that are shown to influence children's behavioral and psychosocial adjustment are overlooked. The aim of the present study was to reveal how parenting style and family function as well as BAP effect psychological adjustment of siblings of children with autism. The Participants included 65 parents who had one child with an Autism Spectrum Disorder and one typically developing child. Of the children with ASDs, 40 were boys and 25 were girls; and they were diagnosed with ASDs by a psychiatrist based on DSM-IV-TR criteria and Autism Diagnostic Interview-Revised (ADI-R). The Persian versions of the six scales were used to collect data from the families. Pearson's correlation test and regression analysis were used to determine which variables were related to the psychological adjustment of sibling of children with ASDs and which variables predicted it better. Significant relationships were found between Strengths and Difficulties Questionnaire (SDQ) total difficulties, prosocial behaviors and ASDs symptoms severity, parenting styles and some aspects of family function. In addition, siblings who had more BAP characteristics had more behavior problems and less prosocial behavior. Behavioral problems increased and prosocial behavior decreased with permissive parenting style. Besides, both of authoritarian and authoritative parenting styles led to a decrease in behavioral problems and an increase in prosocial behaviors. Our findings revealed that some aspects of family function (affective responsiveness, roles, problem solving and behavior control) were significantly

Disturbed sleep and a family history of alcohol dependence (AD) are risk factors for developing AD, yet the underlying relationship between them is unclear among individuals with AD. Understanding these inherited associations will help us not only identify risk for development of these comorbid disorders, but also individualize treatment at this interface. We evaluated whether a first-degree family history of AD (FH+) was a risk factor for sleep continuity disturbance in patients with AD. We also evaluated whether alcohol use or mood disturbance moderated the relationship between FH and sleep. We analyzed cross-sectional baseline data from an alcohol clinical trial in a sample of individuals with AD (N = 280). Their family history of AD among nuclear family members, sleep complaints, alcohol use (over the last 90 days), and mood disturbance were assessed using the Family History Interview for Substance and Mood Disorders, Medical Outcomes Study Sleep Scale, Time Line Follow-Back Interview, and Profile of Mood States-Short Form, respectively. A FH + status (65% of subjects) was significantly associated with lower model estimated mean sleep adequacy (β = - 7.05, p = 0.02) and sleep duration (β = - 0.38, p = 0.04) scale scores. FH was not associated with sleep disturbance scale. No significant moderating effect involving alcohol use or mood disturbance was seen. Family history of AD is a unique risk factor for sleep complaints in AD. Non-restorative sleep and sleep duration may be noteworthy phenotypes to help probe for underlying genotypic polymorphisms in these comorbid disorders. Published by Elsevier B.V.

Abnormal regional activity and functional connectivity of the default-mode network (DMN) have been reported in schizophrenia. However, previous studies may have been biased by unmatched case-control design. To limit such bias, the present study used both the family-based case-control design and the traditional case-control design to investigate abnormal regional activity of the DMN in patients with schizophrenia at rest.Twenty-eight first-episode, drug-naive patients with schizophrenia, 28 age-, sex-matched unaffected siblings of the patients (family-based controls, FBC), and 40 healthy controls (HC) underwent resting-state functional magnetic resonance imaging (fMRI) scans. The group-independent component analysis and fractional amplitude of low-frequency fluctuation (fALFF) methods were used to analyze the data.Patients with schizophrenia show increased fALFF in an overlapped region of the right superior medial prefrontal cortex (MPFC) relative to the FBC and the HC. Compared with the HC, the patients and the FBC exhibit increased fALFF in an overlapped region of the left posterior cingulate cortex/precuneus (PCC/PCu). Furthermore, the z values of the 2 overlapped regions can separate the patients from the FBC/HC, and separate the patients/FBC from the HC with relatively high sensitivity and specificity.Both the family-based case-control and traditional case-control designs reveal hyperactivity of the DMN in first-episode, drug-naive patients with paranoid schizophrenia, which highlights the importance of the DMN in the neurobiology of schizophrenia. Family-based case-control design can limit the confounding effects of environmental factors in schizophrenia. Combination of the family-based case-control and traditional case-control designs may be a viable option for the neuroimaging studies.

Genome-wide association studies (GWAS) of schizophrenia have yielded more than 100 common susceptibility variants, and strongly support a substantial polygenic contribution of a large number of small allelic effects. It has been hypothesized that familial schizophrenia is largely a consequence of inherited rather than environmental factors. We investigated the extent to which familiality of schizophrenia is associated with enrichment for common risk variants detectable in a large GWAS. We analyzed single nucleotide polymorphism (SNP) data for cases reporting a family history of psychotic illness (N = 978), cases reporting no such family history (N = 4,503), and unscreened controls (N = 8,285) from the Psychiatric Genomics Consortium (PGC1) study of schizophrenia. We used a multinomial logistic regression approach with model-fitting to detect allelic effects specific to either family history subgroup. We also considered a polygenic model, in which we tested whether family history positive subjects carried more schizophrenia risk alleles than family history negative subjects, on average. Several individual SNPs attained suggestive but not genome-wide significant association with either family history subgroup. Comparison of genome-wide polygenic risk scores based on GWAS summary statistics indicated a significant enrichment for SNP effects among family history positive compared to family history negative cases (Nagelkerke’s R2 = 0.0021; P = 0.00331; P-value threshold <0.4). Estimates of variability in disease liability attributable to the aggregate effect of genome-wide SNPs were significantly greater for family history positive compared to family history negative cases (0.32 and 0.22, respectively; P = 0.031).We found suggestive evidence of allelic effects detectable in large GWAS of schizophrenia that might be specific to particular family history subgroups. However, consideration of a polygenic risk score indicated a significant enrichment among family history

Objective To comprehensively assess family characteristics of adolescents with severe obesity and whether family factors impact weight loss outcomes following weight loss surgery (WLS). Methods Multi-site prospective data from 138 adolescents undergoing WLS and primary caregivers (Adolescent Mage=16.9; MBMI= 51.5 kg/m2; Caregiver: Mage=44.5; 93% female) and 83 non-surgical comparators (NSComp: Adolescent: Mage=16.1; MBMI= 46.9 kg/m2; Caregiver: Mage=43.9; 94% female) were collected using standardized measures at pre-surgery/baseline, 1- and 2-years. Results The majority (77.3%) of caregivers were obese, with rates of caregiver WLS significantly higher in the WLS (23.8%) versus NSComp group (3.7%, p<.001). Family dysfunction was prevalent (≈1 in every 2–3 families), with rates higher for NSComp than the WLS group. For the WLS group, pre-operative family factors (i.e., caregiver BMI or WLS history, dysfunction, social support) were not significant predictors of adolescent weight loss at 1- and 2-years post-operatively, although change in family functioning over time emerged as a significant correlate of percent weight loss. Conclusions Rates of severe obesity in caregivers as well as family dysfunction were clinically noteworthy, although not related to adolescent weight loss success following WLS. However, change in family communication and emotional climate over time emerged as potential targets to optimize weight loss outcomes. PMID:27753228

This study examined the relationship of 2 types of workplace flexibility to work-family fit and work, personal, and marriage-family outcomes using data (N = 1,601) representative of employed persons in Singapore. We hypothesized that perceived and used workplace flexibility would be positively related to the study variables. Results derived from structural equation modeling revealed that perceived flexibility predicted work-family fit; however, used flexibility did not. Work-family fit related positively to each work, personal, and marriage-family outcome; however, workplace flexibility only predicted work and personal outcomes. Findings suggest work-family fit may be an important facilitating factor in the interface between work and family life, relating directly to marital satisfaction and satisfaction in other family relationships. Implications of these findings are discussed. Copyright 2008 APA, all rights reserved.

Objective This nation-wide register-based study investigated how often phobic disorders (PHO) and co-morbid disorders occur in affected families compared to control families. Furthermore, the study addressed the impact of sex, year of birth, and degree of urbanization in terms of risk factors. Method A total of N = 746 child and adolescent psychiatric participants born between 1969 and 1986 and registered in the Danish Psychiatric Central Research Register (DPCRR) with a diagnosis of a mental disorder before the age of 18, and developed PHO at some point during their life-time until a maximum age of 40 years were included. In addition, N = 2229 controls without any diagnosis of mental disorders before age 18 and that were matched for age, sex, and residential region were included. Diagnoses of mental disorders were also obtained from the first- degree relatives as a part of the Danish Three Generation Study (3GS). A family load component was obtained by using various mixed regression models. Results PHO occurred significantly more often in case than in control families, in particular, in mothers and siblings. Substance use disorders (SUD), Depressive disorders (DEP), anxiety disorders (ANX) and personality disorders (PERS) in the family were significantly associated with specific phobia in the case-probands. After controlling for various mental disorders comorbid to PHO it was found that some of the family transmission could be caused by various other mental disorders in family members rather than the PHO itself. Female sex and more recent year of birth were further risk factors while region of residence was not related to the manifestation of PHO. Case-relatives did not develop PHO earlier than control relatives. After adjusting for various additional explanatory variables, the family load explained only 0.0013% of the variance in the manifestation of PHO in the case-probands Discussion These findings, based on a very large and representative dataset, provide

Heavy episodic drinking is widespread among adolescents, with serious health risks, including abuse / dependence in adulthood. The aim of this paper is to analyze the influence of negative mood states and some family variables on this type of drinking behavior among Catalan adolescents. Cross sectional study of a representative sample of adolescents (age 14-18 years) from Catalonia (Second Wave, Panel of Families and Children) (2006-2010). Separate logistic regression models are run for women (n = 1,459) and men (n = 1,105) to assess whether negative mood states (self-perceived) are associated with heavy episodic drinking measured as binge drinking at least twice a month or more in the last year. It is estimated to what extent these effects are attributable to familial factors. Feelings of sadness are associated with binge drinking among male adolescents (OR 2.7). Feeling pressured by parents keeps also a positive association with binge drinking among both sexes (OR 1.8 for males and OR 2.1 for women). Women from low-middle and high income groups are more likely to engage in binge drinking (OR 1.6 and OR, 1.7 respectively). Migrant family background (OR 0.4) and parental control of arrival home on weekend (OR 0.6) are negatively related to binge drinking among female adolescents. Negative mood states are associated with heavy episodic drinking. Socio-economic and family factors have stronger effect on women than on men.

The study aimed to evaluate the differences between groups of encopresis patients with constipation and without constipation. The Symptom Checklist- 90-Revised, the COPE Questionnaire, the Relationship Scales Questionnaire, the McMaster Family Assessment Device and the Parenting Style Scale were used to evaluate, respectively, maternal psychiatric symptoms, coping abilities, attachment style, family functioning and children's perceptions of parenting behaviors. Psychiatric diagnoses were evaluated using the K-SADS. A higher level of maternal psychiatric symptoms, impaired role and affective involvement functioning of the family and less psychological autonomy were observed in the group of encopresis patients with constipation than in the group of encopresis patients without constipation. No significant differences were found between the groups in psychiatric comorbidities, maternal coping abilities and attachment style. The two groups had a similar pattern of comorbid psychiatric disorders and maternal psychological factors, although some familial factors-related mainly to parental authority-were differentiated in the encopresis with constipation group.

This study examined the role of demographic characteristics, psychological factors, and family functioning on attendance in a randomized controlled trial of a family-based pediatric obesity program. Participants included 155 children between the ages of 4 and 7 years (M age = 5.77, 57.4% female, 73.6% black, M body mass index = 25.5) and their primary caregivers who were randomized to the treatment group. Three groups of participants were created based on their patterns of attendance during the program: (1) noncompleters, (2) partial completers, and (3) completers. Results indicated no differences among the attendance groups in child gender, child body mass index, or child psychological functioning. Significant group differences were found with respect to race/ethnicity, parent marital status, and family income, such that noncompleters were more likely to be racial/ethnic minorities, to living in single parent households, and to have lower incomes than partial completers and completers. After controlling for the effects of these sociodemographic risk factors, noncompleters, and partial completers reported more family dysfunction characterized by high levels of disengagement than completers. Adapting existing weight management programs to include a focus on family engagement in the early stages of treatment may help to improve participation in family-based obesity interventions targeting high risk, socioeconomically disadvantaged youth.

Dating violence (DV) is a widespread social issue that has numerous deleterious repercussions on youths' health. Family and peer risk factors for DV have been widely studied, but with inconsistent methodologies, which complicates global comprehension of the phenomenon. Protective factors, although understudied, constitutes a promising line of research for prevention. To date, there is no comprehensive quantitative review attempting to summarize knowledge on both family and peer factors that increase or decrease the risk for adolescents and emerging adults DV victimization. The current meta-analysis draws on 87 studies with a total sample of 278,712 adolescents and young adults to examine effect sizes of the association between various family and peer correlates of DV victimization. Results suggest small, significant effect sizes for all the family (various forms of child maltreatment, parental support, and parental monitoring) and peer factors (peer victimization, sexual harassment, affiliation with deviant peers, and supportive/prosocial peers) in the prediction of DV. With few exceptions, forms of DV (psychological, physical, and sexual), gender, and age did not moderate the strength of these associations. In addition, no difference was found between the magnitude of family and peer factors' effect sizes, suggesting that these determinants are equally important in predicting DV. The current results provide future directions for examining relations between risk and protective factors for DV and indicate that both peers and family should be part of the development of efficient prevention options.

Objective To explore the importance of early life factors shared by siblings, such as parental socioeconomic position, parental practices, housing and neighbourhood, for the association between cardiovascular disease (CVD) risk factors and mortality from CVD, ischaemic heart disease (IHD) and cerebrovascular disease. Methods Norwegian health surveys (1974–2003) were linked with data from the Norwegian Family Based Life Course Study and the Cause of Death Registry. Participants with at least one full sibling among survey participants (n=2 71 643) were included. Data on CVD risk factors, body mass index (BMI), height, systolic blood pressure (SBP) and total cholesterol (TC) were stratified into ‘low’, ‘medium’ and ‘high’ risk, and smoking to ‘daily smoking’ and ‘not daily smoking’. Results Mean age of participants was 41 years, mean follow-up time was 19 years and during follow-up 2512 died from CVD. For each category of increased risk factor level, the per step HR of CVD mortality was increased by 1.91 (95% CI 1.78 to 2.05) for SBP, 1.67 (1.58 to 1.76) for TC, 1.44 (1.36 to 1.53) for BMI, 1.26 (1.18 to 1.35) for height and 2.89 (2.66 to 3.14) for smoking. In analyses where each sibship (groups of full siblings) had a group-specific baseline hazard, these associations were attenuated to 1.74, 1.51, 1.29, 1.18 and 2.63, respectively. The associations between risk factors and IHD mortality followed the same pattern. Conclusion Early life family factors explained a small part of the association between risk factors and mortality from CVD and IHD in a relatively young sample. PMID:28878947

Key factors affecting dying children and their families.

The death of a child alters the life and health of others immediately and for the rest of their lives. How a child dies influences parents' abilities to continue their role functions as well as siblings' abilities to make and maintain friendships, and may be the basis for health care providers' decisions to exit direct care roles. Thus, facilitating a "good death"-an obvious care priority for all involved with the dying child-ought also to be a priority for the health of bereaved families and affected health care providers. Making this a care priority is complicated by a serious lack of data, as details of the last hours or weeks of a dying child or adolescent's life are largely unknown. The purpose of this paper is to identify key factors that affect the course of dying children and adolescents and that of their bereaved survivors, and to link those key factors to needed research that could produce clinically relevant findings to improve the care of these patients. Key factors described here include suffering (physical, psychological, and spiritual), communication, decision making, prognostic ambiguities, ability of the seriously ill child to give assent to research participation, and educational preparation of health care providers to give competent end-of-life care.

The concepts of quality of life and family quality of life (FQOL) are increasingly being studied in the field of intellectual disabilities (ID) in China as important frameworks for: (1) assessing families' need for supports and services; (2) guiding organisational and service delivery system changes; and (3) evaluating quality family outcomes. The present study focused on exploring the perceptions of Chinese families who have a child with an ID regarding FQOL as well as examining the factor structure of FQOL concept from Chinese families. The Chinese version of the Family Quality of Life Scale was used to survey Chinese families living in the urban and suburban areas of Beijing who have a child with ID. A total of 442 families participated in this study. Confirmatory factor analysis was used to test the factor structure of FQOL. Multivariate analysis was also used to examine group differences among families in terms of family demographic variables. A five-factor structure of the FQOL construct was found in the Chinese sample, suggesting a similar factor structure found from US families in the literature. Different living conditions (e.g. housing and transportation) tended to affect significantly families' satisfaction ratings of their FQOL. It is also found that family income and severity of disability of the child are predictors of families' satisfaction ratings of FQOL. The preliminary findings of this study suggest a cross-cultural factor structure comparability of FQOL between samples in the USA and China. Results call for further examination of the family-centred service and support as a mediator on the interactive relationship between family characteristics, family needs and FQOL outcomes. © 2011 The Authors.

Nuclear Factor Y (NF-Y) is a heterotrimeric complex formed by NF-YA/NF-YB/NF-YC subunits that binds to the CCAAT-box in eukaryotic promoters. In contrast to other organisms, in which a single gene encodes each subunit, in plants gene families of over 10 members encode each of the subunits. Here we report that five members of the Arabidopsis thaliana NF-YA family are strongly induced by several stress conditions via transcriptional and miR169-related post-transcriptional mechanisms. Overexpression of NF-YA2, 7 and 10 resulted in dwarf late-senescent plants with enhanced tolerance to several types of abiotic stress. These phenotypes are related to alterations in sucrose/starch balance and cell elongation observed in NF-YA overexpressing plants. The use of transcriptomic analysis of transgenic plants that express miR169-resistant versions of NF-YA2, 3, 7, and 10 under an estradiol inducible system, as well as a dominant-repressor version of NF-YA2 revealed a set of genes, whose promoters are enriched in NF-Y binding sites (CCAAT-box) and that may be directly regulated by the NF-Y complex. This analysis also suggests that NF-YAs could participate in modulating gene regulation through positive and negative mechanisms. We propose a model in which the increase in NF-YA transcript levels in response to abiotic stress is part of an adaptive response to adverse environmental conditions in which a reduction in plant growth rate plays a key role.

Family relationships are widely recognized as playing a role in adolescent alcohol use. Although family relationships and parenting vary by culture, limited research has explored these relationships in Latin America. We sought to determine which family factors are associated with adolescent alcohol use in Callao, Peru. Data come from a cross-sectional survey conducted in a public secondary school in Callao, Peru in 2007. A total of 180 11th grade students are included in the analysis. Our main outcome measure was problem drinking, defined as self-report of having ever consumed beer, wine, spirits, or hard alcohol to a point of drunkenness. Logistic regression was used to determine if odds of problem drinking varied by level of parental monitoring (knowledge of activities and whereabouts), positive family relationships, or family conflict, while controlling for demographic and peer variables. Low levels of parental monitoring and low levels of positive family relationships were each associated with significantly higher odds of lifetime problem drinking in analyses adjusted for deviant peer affiliation along with sociodemographic variables (odds ratio (OR) = 4.2; 95% confidence interval (CI): 1.3-13.5; OR = 4.4; 95% CI: 1.5-13.0, respectively). Although family conflict was associated with elevated odds of lifetime problem drinking, this did not reach significance (adjusted OR = 2.01; 95% CI: 0.8-5.1). Conclusions/Importance: Interventions designed to prevent adolescent alcohol use in urban Peru may benefit from promoting positive family interactions and parental monitoring skills.

Alcoholism is considered an associated factor to the family dysfunction, revealing the need for health professionals to overcome the purely individual perspective to offer a systemic focus. The aim of this study was to analyze the concept dysfunctional family in the context of alcoholism. The study followed the Concept Analysis Model and steps of integrative literature review. It was identifi ed the antecedents of alcoholism, the attributes and the consequent dysfunctional family and it was reported a model case which illustrated the presence of these elements. It was observed that this is a broad concept, subjective and complex, with emphasis on studies on the consequents related to children of alcoholics.

This study examined the influence of hurricane impact as well as family and individual risk factors on posttraumatic stress (PTS) symptoms and substance involvement among clinically referred adolescents affected by Hurricane Katrina. A total of 80 adolescents (87% male; 13-17 years old; mean age = 15.6 years; 38% minorities) and their parents were interviewed at the adolescent's intake into substance abuse treatment, 16 to 46 months postdisaster. Independent measures included hurricane impact variables (initial loss/disruption and perceived life threat); demographic and predisaster variables (family income, gender, predisaster adolescent substance use, predisaster trauma exposure, and parental substance abuse); postdisaster family factors (parental psychopathology, family cohesion, and parental monitoring); and postdisaster adolescent delinquency. Hierarchical multivariate regression analyses showed that adolescent substance involvement was associated with higher family income, lower parental monitoring (adolescent report), and more adolescent delinquency. Adolescent-reported PTS symptoms were associated with greater hurricane-related initial loss/disruption, lower family cohesion (adolescent report), and more adolescent delinquency, whereas parent-reported adolescent PTS symptoms were associated with greater parental psychopathology, lower parental monitoring (adolescent report), and lower family cohesion (parent report). The results suggest that hurricane impact was related only to adolescent-reported PTS. However, certain postdisaster family and individual risk factors (low family cohesion and parental monitoring, more adolescent delinquency) were associated both with adolescent substance involvement and with PTS symptoms. Identification of these factors suggests directions for future research as well as potential target areas for screening and intervention with substance-abusing adolescents after disasters.

The WRKY transcription factors function in plant growth and development, and response to the biotic and abiotic stresses. Although many studies have focused on the functional identification of the WRKY transcription factors, much less is known about molecular phylogenetic and global expression analysis of the complete WRKY family in maize. In this study, we identified 136 WRKY proteins coded by 119 genes in the B73 inbred line from the complete genome and named them in an orderly manner. Then, a comprehensive phylogenetic analysis of five species was performed to explore the origin and evolutionary patterns of these WRKY genes, and the result showed that gene duplication is the major driving force for the origin of new groups and subgroups and functional divergence during evolution. Chromosomal location analysis of maize WRKY genes indicated that 20 gene clusters are distributed unevenly in the genome. Microarray-based expression analysis has revealed that 131 WRKY transcripts encoded by 116 genes may participate in the regulation of maize growth and development. Among them, 102 transcripts are stably expressed with a coefficient of variation (CV) value of <15%. The remaining 29 transcripts produced by 25 WRKY genes with the CV value of >15% are further analysed to discover new organ- or tissue-specific genes. In addition, microarray analyses of transcriptional responses to drought stress and fungal infection showed that maize WRKY proteins are involved in stress responses. All these results contribute to a deep probing into the roles of WRKY transcription factors in maize growth and development and stress tolerance. PMID:22279089

Family satisfaction with end-of-life care in the ICU has not previously been systematically reviewed. Our objective was to perform a review, synthesizing published data identifying factors associated with family satisfaction with end-of-life care in critically ill adult populations. The following electronic databases were searched: MEDLINE (Medical Literature Analysis and Retrieval System Online), MEDLINE Updated, EMBASE (Excerpta Medical Database), CINAHL (Cumulative Index to Nursing and Allied Health Literature), PsycInfo, and PubMed. Two authors reviewed retrieved titles and abstracts. Studies describing nonadult and non-ICU populations or not addressing end-of-life care, family satisfaction, or factors affecting satisfaction were excluded. The remaining articles underwent full review and data extraction by two authors. Quality was assessed using a checklist based on the recommendations of the Consolidated Standards for Reporting Trials group. The search yielded 1,072 articles, with 23 articles describing 14 studies meeting inclusion criteria. All studies obtained satisfaction data from family members via surveys and structured interviews. Specific communication strategies increasing satisfaction included: expressions of empathy, nonabandonment, and assurances of comfort and provision of written information. Additionally, support for shared decision-making, family presence at time of death, and specific patient-care measures such as extubation before death were associated with increased satisfaction. Good-quality communication, support for shared decision-making, and specific patient-care measures were associated with increased satisfaction with end-of-life care. Assessing the family's desire to participate in shared decision-making may also be an important factor. Few interventions increased satisfaction. Future research is needed to further define optimal communication strategies, understand effective integration of palliative care into the ICU, and define

The Multivariate Roles of Family Instability and Interparental Conflict in Predicting Children's Representations of Insecurity in the Family System and Early School Adjustment Problems.

This study examined the moderating role of family instability in relations involving destructive interparental conflict, children's internal representations of insecurity in the family system, and their early school maladjustment. Two hundred forty-three preschool children (M age = 4.60 years; 56 % girls) and their families participated in this multi-method (i.e., observations, structured interview, surveys) multi-informant (i.e., observer, parent, teacher), longitudinal study. Findings indicated that the mediational role of children's insecure family representations in the pathway between destructive interparental conflict and children's adjustment problems varied significantly depending on the level of family instability. Interparental conflict was specifically associated with insecure family representations only under conditions of low family instability. In supporting the role of family instability as a vulnerable-stable risk factor, follow up analyses revealed that children's concerns about security in the family were uniformly high under conditions of heightened instability regardless of their level of exposure to interparental conflict.

Teosinte branched 1/cycloidea/proliferating cell factor 1 (TCP) proteins are a large family of transcriptional regulators in angiosperms. They are involved in various biological processes, including development and plant metabolism pathways. In this study, a total of 52 TCP genes were identified in apple (Malus domestica) genome. Bioinformatic methods were employed to predicate and analyse their relevant gene classification, gene structure, chromosome location, sequence alignment and conserved domains of MdTCP proteins. Expression analysis from microarray data showed that the expression levels of 28 and 51 MdTCP genes changed during the ripening and rootstock-scion interaction processes, respectively. The expression patterns of 12 selected MdTCP genes were analysed in different tissues and in response to abiotic stresses. All of the selected genes were detected in at least one of the tissues tested, and most of them were modulated by adverse treatments indicating that the MdTCPs were involved in various developmental and physiological processes. To the best of our knowledge, this is the first study of a genomewide analysis of apple TCP gene family. These results provide valuable information for studies on functions of the TCP transcription factor genes in apple.

Watermelon (Citrullus lanatus) is one xerophyte that has relative higher tolerance to drought and salt stresses as well as more sensitivity to cold stress, compared with most model plants. These characteristics facilitate it a potential model crop for researches on salt, drought or cold tolerance. In this study, a genome-wide comprehensive analysis of the ClNAC transcription factor (TF) family was carried out for the first time, to investigate their transcriptional profiles and potential functions in response to these abiotic stresses. The expression profiling analysis reveals that several NAC TFs are highly responsive to abiotic stresses and development, for instance, subfamily IV NACs may play roles in maintaining water status under drought or salt conditions, as well as water and metabolites conduction and translocation toward fruit. In contrast, rapid and negative responses of most of the ClNACs to low-temperature adversity may be related to the sensitivity to cold stress. Crosstalks among these abiotic stresses and hormone (abscisic acid and jasmonic acid) pathways were also discussed based on the expression of ClNAC genes. Our results will provide useful insights for the functional mining of NAC family in watermelon, as well as into the mechanisms underlying abiotic tolerance in other cash crops. PMID:27491393

This study investigates the extent to which friendship network, family relations, and school context are related to adolescent cigarette smoking. Friendship network is measured in terms of delinquent peers; family relations in terms of parental supervision; and school environment in terms of objective (eg, antismoking policy) and subjective (eg, school attachment) characteristics. Findings are based on the secondary analysis of the health behavior in school-aged children, 2009-2010. Two-level hierarchical generalized linear models are estimated using hierarchical linear modeling 7. At the student level, ties to delinquent friends is significantly related to higher odds of smoking, while greater parental supervision is associated with lower odds. At the school level, antismoking policy and curriculum independently lower smoking behavior. Better within-class peer relations, greater school attachment, and higher academic performance are also negatively related to smoking. Last, the positive association between delinquent friends and smoking is weaker in schools with a formally enacted antismoking policy. However, this association is stronger in schools with better peer relations. Adolescent smoking behavior is embedded in a broader ecological setting. This research reveals that a proper understanding of it requires comprehensive analysis that incorporates factors measured at individual (student) and contextual (school) levels. © 2018, American School Health Association.
