RESUMO

IMPORTANCE: Most unwanted sexual contact victimization (USCV) research utilizes predominantly white, cisgender, heterosexual college student samples. Estimates of USCV prevalence and demographic variation can determine the need for dedicated funding and culturally relevant campus services for students in high-risk groups. OBJECTIVE: To estimate the national prevalence and demographic variation in self-reported USCV within the first three months of college. DESIGN: Data are from the Sexual Assault Prevention for Undergrads (SAPU) (2020-2021) dataset. SAPU is an online intervention program administered to students on more than 600 college campuses in the United States (N = 250,359). Group differences were assessed by race/ethnicity, gender identity, and sexual identity, and then stratified by gender to assess within-gender group differences. SETTING: The SAPU dataset includes public and private institutions and 2-year and 4-year colleges with varying sizes of enrollment. PARTICIPANTS: The sample is demographically diverse, and consists of newly matriculated U.S. college students, most of whom complete the SAPU program within the first three months of enrollment. MAIN OUTCOMES AND MEASURES: The primary outcome measure is self-reported USCV within the first three months of college enrollment, analyzed for subgroup differences. We hypothesized that USCV would be higher among students from racial/ethnic, gender, and sexual minority populations. RESULTS: Nearly 8% of transgender men reported USCV, followed by 7.4% of transgender women, 7.4% of genderqueer/gender non-conforming students, 4.5% of women, and 1.5% of men. Several subgroups reported exceedingly high rates of USCV, including Black students who identified as transgender women (35.7%) and American Indian/Alaska Native/Native Hawaiian/Pacific Islander students who identified as trans men (55.6%) or genderqueer/gender non-conforming (41.7%). CONCLUSIONS AND RELEVANCE: Universal and targeted (selective and indicated) intervention programs are needed to lessen USCV, particularly among gender minority students who also identify as Black, Indigenous, other person of color, or as a sexual minority.

RESUMO

For new fathers, parenting stress is a risk factor for impaired early parenting and child maltreatment perpetration. Predictors of parenting stress, including fathers' own experiences of trauma, could be useful intervention targets to support new fathers. We aim to examine associations between new fathers' own histories of child maltreatment, and their perinatal mental health, relationships, and parenting stress. We recruited 298 first-time fathers for a survey that measured child maltreatment history, trauma sequelae including posttraumatic stress disorder (PTSD), major depressive disorder (MDD), interpersonal reactivity, substance use, anger expression, coparenting quality, and parenting stress. On the Parenting Stress Index (PSI) (from 36 to 180), bivariate analysis demonstrated that new fathers who experienced child maltreatment (n = 94) had significantly higher parenting stress (x̅ = 85.3, σ = 18.7) than those who did not (n = 204; x̅ = 76.0, σ = 16.6; P < .000). Hierarchical linear regression modeling indicated that a child maltreatment history, PTSD, and MDD were significantly associated with parenting stress. The strongest predictors of parenting stress were coparenting quality and complex trauma sequelae-interpersonal reactivity and anger expression. Interventions to reduce fathers' parenting stress by targeting known mental health and relationship sequelae of maltreatment are promising avenues to breaking intergenerational transmission of child maltreatment and psychiatric vulnerability.


Para nuevos papás, el estrés de crianza es un factor de riesgo para la deficiente crianza temprana y para cometer maltrato infantil. Los factores de predicción del estrés de crianza, incluyendo las propias experiencias de trauma de los papás, pueden ser útiles metas de intervención para apoyar a los nuevos papás. Nos propusimos examinar las asociaciones entre las propias historias de maltrato de los nuevos papás, y su salud mental perinatal, relaciones y estrés de crianza. Reclutamos 298 papás primerizos para una encuesta que medía la historia de maltrato infantil, la secuela de trauma incluyendo el trastorno de estrés postraumático (PTSD), el trastorno depresivo serio (MDD), la reactividad interpersonal, el uso de sustancias, la expresión de ira, la calidad de la crianza compartida, así como el estrés de crianza. En el Índice de Estrés de Crianza (de 36-180), los análisis bivariantes demostraron que los nuevos papás que habían experimentado maltrato infantil (N = 94) tenían significativamente un mayor estrés de crianza (x̅ = 85.3, σ = 18.7) que aquellos que no habían tenido tal experiencia (N = 204; x̅ = 76.0, σ = 16.6; P<.000). El modelo de regresión lineal jerárquica indicó que una historia de maltrato infantil, PTSD y MDD estaban significativamente asociados con el estrés de crianza. Los más fuertes factores de predicción del estrés de crianza fueron la calidad de la crianza compartida y la compleja secuela de trauma-la reactividad interpersonal y la expresión de la ira. Las intervenciones para reducir el estrés de crianza de los papás por medio del enfoque en la salud mental conocida y las secuelas en la relación del maltrato son una vía prometedora para romper la transmisión intergeneracional del maltrato infantil y la vulnerabilidad siquiátrica.


Pour les nouveaux pères le stress de parentage est un facteur de risque pour le parentage précoce compromis et la perpétration de maltraitance de l'enfant. Les prédicteurs de stress de parentage, y compris les propres expériences de trauma des pères, pourraient être des cicles d'intervention utiles afin de soutenir les nouveaux pères. Nous nous sommes donné pour but d'examiner les liens entre le propre passé de maltraitance de l'enfant des nouveaux pères et leur santé mentale périnatale, leurs relations et le stress de parentage. Nous avons recruté 298 nouveaux pères (pères pour la première fois) pour un sondage mesurant l'histoire de la maltraitance de l'enfant, les séquelles de trauma y compris les troubles de stress post-traumatique (TSPT), les troubles dépressifs majeurs (MDD en anglais), la réactivité interpersonnelle, la toxicomanie, l'expression de colère et la qualité du co-parentage ainsi que le stress parental. Pour l'Index de Stress de Parentage (de 36-180), une analyse bivariée a montré que les nouveaux pères qui avaient fait l'expérience de maltraitance de l'enfance (N = 94) avaient un stress de parentage bien plus élevé (x̅ = 85,3, σ = 18,7) que ceux n'en ayant pas fait l'expérience (N = 204; x̅ = 76,0, σ = 16,6; P<,000). Un modèle de régression linéaire hiérarchique a indiqué qu'un passé de maltraitance de l'enfant, le TSPT et le MDD étaient fortement liés au stress de parentage. Les facteurs de prédiction les plus forts de stress de parentage étaient la qualité du co-parentage et les séquelles de trauma complexes - réactivité interpersonnelle et l'expression de la colère. Les interventions pour réduire le stress de parentage des pères en ciblant la santé mentale connue et les séquelles de maltraitance sont un chemin prometteur pour casser la transmission intergénérationnelle de la maltraitance de l'enfant et la vulnérabilité psychiatrique.

RESUMO

The COVID-19 pandemic prompted the early release of thousands of incarcerated individuals, including those with histories of intimate partner violence (IPV) perpetration. Survivor advocates stress the importance of adequate supports for decarcerated individuals during re-entry, and notification and supports for their partners or ex-partners if there is a history of IPV. This survey assessed IPV survivors' expectations of and experiences with decarceration in the state of Michigan. Findings highlight that out of 42 survivors with recently decarcerated (ex-)partners, 64.3% reported helpful behavior on the part of their released partner. By contrast, out of 72 survivors with still-incarcerated (ex-)partners, the same percentage - 64.3% - expected harmful behavior from their partner if released. Decarceration efforts may distinguish between individuals who are likely to harm versus help (ex-)partners upon release. Nonetheless, survivors reported several unmet needs, indicating the need for better re-integration services for decarcerated individuals and their families.

RESUMO

Early relational health between caregivers and children is foundational for child health and well-being. Children and caregivers are also embedded within multiple systems and sectors, or a "child-serving ecosystem", that shapes child development. Although the COVID-19 pandemic has made this embeddedness abundantly clear, systems remain siloed and lack coordination. Fostering relational health amongst layers of this ecosystem may be a way to systematically support young children and families who are facing adversity. We integrate theory, examples, and empirical findings to develop a conceptual model informed by infant mental health and public health frameworks that illustrates how relational health across the child-serving ecosystem may promote child health and well-being at a population level. Our model articulates what relational health looks like across levels of this ecosystem from primary caregiver-child relationships, to secondary relationships between caregivers and child-serving systems, to tertiary relationships among systems that shape child outcomes directly and indirectly. We posit that positive relational health across levels is critical for promoting child health and well-being broadly. We provide examples of evidence-based approaches that address primary, secondary, and tertiary relational health, and suggest ways to promote relational health through cross-sector training and psychoeducation in the science of early development. This model conceptualizes relational health across the child-serving ecosystem and can serve as a template for promoting child health and well-being in the context of adversity.


La salud de la temprana relación entre quienes prestan cuidado y los niños es fundamental para la salud y el bienestar del niño. Los niños y quienes les cuidan forman parte de múltiples sistemas y sectores, o un "ecosistema de servicio al niño," que moldea el desarrollo del niño. Aunque la pandemia del COVID-19 ha demostrado abundante y claramente esta pertenencia, los sistemas permanecen aislados y les hace falta coordinación. Fomentar la salud de la relación entre las capas del ecosistema pudiera ser una manera de apoyar sistemáticamente a los niños pequeños y familias que se enfrentan con situaciones adversas. Presentamos un modelo conceptual con base en marcos de trabajo de la salud mental infantil y la salud pública que ilustra cómo la salud de la relación a lo largo del ecosistema de servicio al niño pudiera promover el desarrollo del niño al nivel de grupo de población. Nuestro modelo articula cómo aparece la salud de la relación a lo largo de los niveles del ecosistema desde las relaciones entre quien presta el cuidado primario y el niño, hasta las relaciones secundarias entre quienes prestan el cuidado y loa sistemas de servicio al niño, y las relaciones terciarias entre sistemas que amoldan directa e indirectamente los resultados en el niño. Una positiva salud de la relación a través de todos los niveles es esencial para promover la salud y el bienestar del niño de manera amplia. Describimos ejemplos específicos de salud de la relación primaria, secundaria y terciaria, y sugerimos maneras de promover la salud de la relación a través del entrenamiento intersectorial y la educación sicológica dentro de la ciencia del desarrollo temprano. Este modelo conceptualiza la salud de la relación a lo largo del ecosistema de servicio al niño y puede ser un esquema patrón para promover el desarrollo del niño dentro del contexto de situaciones adversas.


La Santé Relationnelle Précoce entre les personnes prenant soin des enfants et les enfants est fondamentale pour la santé de l'enfant et son bien-être. Les enfants et les personnes prenant soin d'eux sont encastrés dans de multiples systèmes et des secteurs, ou un « écosystème ¼ servant l'enfant qui forme le développement de l'enfant. Bien que la pandémie du Covid19 ait rendu cet encastrement très clair, les systèmes demeurent compartimentés et manquent de coordination. Cultiver la santé relationnelle au sein des couches de l'écosystème pourrait s'avérer être une manière de soutenir des jeunes enfants et les familles faisant face aux obstacles. Nous présentons un modèle conceptuel informé par les structures de la santé mentale du nourrisson et de la santé publique qui illustre la manière dont la santé relationnelle au travers de l'écosystème servant les enfants peut promouvoir le développement de l'enfant au niveau de la population. Notre modèle articule ce à quoi la santé relationnelle ressemble au travers des niveaux de l'écosystème, des relations entre la personne principale qui s'occupe de l'enfant et l'enfant aux relations secondaires entre les personnes prenant soin de l'enfant et les systèmes servant l'enfant, jusqu'aux relations tertiaires entres les systèmes qui donnent forme aux résultats directement et indirectement. Une santé relationnelle positive au travers de tous les niveaux est critique pour la promotion de la santé de l'enfant et de son bien-être en général. Nous décrivons des exemples spécifiques de santé relationnelle primaire, secondaire et tertiaire, et suggérons des manières de promouvoir la santé relationnelle au travers de la formation entre secteurs et de la psychoéducation dans la science du développement précoce. Ce modèle conceptualise la santé relationnelle au travers de l'écosystème servant l'enfant et peut servir de modèle pour la promotion du développement de l'enfant dans le contexte de l'adversité.

RESUMO

This commentary refers to research by IJzendoorn and colleagues (2019), who conducted an umbrella synthesis on child maltreatment antecedents and interventions. Comments that I offer underscore the valuable contribution of this work for ongoing research, policy, and practice relevant to the etiology and prevention of child maltreatment. The synthesis brings clarity to a growing and diverse body of scholarship and draws attention to gaps in the literature that must be addressed if to advance well-designed and theoretically robust interventions, and to more rapidly bring promising programs to scale. The work presented by the authors is timely and persuasive, offering important insights and guidance that will be appreciated by the journal's readership.

RESUMO

Lipid metabolism plays a critical role in female reproduction. During oogenesis, maturing oocytes accumulate high levels of neutral lipids that are essential for both energy production and the synthesis of other lipid molecules. Metabolic pathways within the ovary are partially regulated by protein kinases that link metabolic status to oocyte development. Although the functions of several kinases in this process are well established, the roles that many other kinases play in coordinating metabolic state with female germ cell development are unknown. Here, we demonstrate that the catalytic activity of casein kinase 2 (CK2) is essential for Drosophila oogenesis. Using an unbiased biochemical screen that leveraged an unusual catalytic property of the kinase, we identified a novel CK2 substrate in the Drosophila ovary, the lipid droplet-associated protein Jabba. We show that Jabba is essential for modulating ovarian lipid metabolism and for regulating female fertility in the fly. Our findings shed light on a CK2-dependent signaling pathway governing lipid metabolism in the ovary and provide insight into the long-recognized but poorly understood association between energy metabolism and female reproduction.

RESUMO

Tumour necrosis factor receptor-associated periodic syndrome (TRAPS) is a hereditary autoinflammatory disorder characterized by recurrent episodes of fever and inflammation. It is associated with autosomal dominant mutations in TNFRSF1A, which encodes tumour necrosis factor receptor 1 (TNF-R1). Our aim was to understand the influence of TRAPS mutations on the response to stimulation of the pattern recognition Toll-like receptor (TLR)-9. Peripheral blood mononuclear cells (PBMCs) and serum were isolated from TRAPS patients and healthy controls: serum levels of 15 proinflammatory cytokines were measured to assess the initial inflammatory status. Interleukin (IL)-1ß, IL-6, IL-8, IL-17, IL-22, tumour necrosis factor (TNF)-α, vascular endothelial growth factor (VEGF), interferon (IFN)-γ, monocyte chemoattractant protein 1 (MCP-1) and transforming growth factor (TGF)-ß were significantly elevated in TRAPS patients' sera, consistent with constitutive inflammation. Stimulation of PBMCs with TLR-9 ligand (ODN2006) triggered significantly greater up-regulation of proinflammatory signalling intermediates [TNF receptor-associated factor (TRAF 3), IL-1 receptor-associated kinase-like 2 (IRAK2), Toll interacting protein (TOLLIP), TRAF6, phosphorylated transforming growth factor-ß-activated kinase 1 (pTAK), transforming growth factor-ß-activated kinase-binding protein 2 (TAB2), phosphorylated TAK 2 (pTAB2), IFN-regulatory factor 7 (IRF7), receptor interacting protein (RIP), nuclear factor kappa B (NF-κB) p65, phosphorylated NF-κB p65 (pNF-κB p65) and mitogen-activated protein kinase kinase (MEK1/2)] in TRAPS patients' PBMCs. This up-regulation of proinflammatory signalling intermediates and raised serum cytokines occurred despite concurrent anakinra treatment and no overt clinical symptoms at time of sampling. These novel findings further demonstrate the wide-ranging nature of the dysregulation of innate immune responses underlying the pathology of TRAPS and highlights the need for novel pathway-specific therapeutic treatments for this disease.

RESUMO

When children experience stress and adversity in their homes and communities, schools become a critically important setting in which to intervene and foster their resilience. Changing practices within schools so that vulnerable and traumatized children are better understood and more compassionately served is a goal shared by many school professionals, yet schools remain poorly equipped to address the needs of these children. Any number of school-based programs have the potential to benefit children with an elevated risk for academic difficulties and mental health disorders, although questions remain as to which programs are most promising, effective, and sustainable. Questions also remain about which programs best serve diverse populations and which have potential to reach the largest number of children, including those who do not outwardly manifest behaviors consistent with an underlying disorder but nonetheless require support. In this review, we take stock of existing programs used in schools to address the social, emotional, and academic needs of children with trauma histories. We summarize components of a various trauma-focused programs, categorized as: (a) individual and group-based approaches, (b) classroom-based approaches, and (c) school-wide approaches. For each category, we review and comment on the state and quality of research findings and provide illustrative examples from the literature to show how programs address trauma in the school context. Findings of the review suggest that empirical evidence currently favors individual and group-based approaches, although classroom-based and school-wide programs may be better positioned for integration, access to services, and sustainability. Implications and recommendations center on future research, practice, and policy.

RESUMO

The special issue highlights work across systems that include child welfare, education, juvenile justice and health, as well as agencies serving adults who are at-risk for high levels of childhood and adult trauma exposure. While articles appearing in the special issue are not divided equally across these systems, they cover important and overlapping concepts within each. Some articles span more than a single system or domain of research, whereas others fit primarily within single area or domain. Articles provide new insights from research on practices, programs, and policies that help to transform systems so they are increasingly more responsive to the needs of vulnerable populations.

RESUMO

Phospholipid-enriched membranes such as the plasma membrane can serve as direct regulators of kinase signaling. Pak1 is involved in growth factor signaling at the plasma membrane, and its dysregulation is implicated in cancer. Pak1 adopts an autoinhibited conformation that is relieved upon binding to membrane-bound Rho GTPases Rac1 or Cdc42, but whether lipids also regulate Pak1 in vivo is unknown. We show here that phosphoinositides, particularly PIP(2), potentiate Rho-GTPase-mediated Pak1 activity. A positively charged region of Pak1 binds to phosphoinositide-containing membranes, and this interaction is essential for membrane recruitment and activation of Pak1 in response to extracellular signals. Our results highlight an active role for lipids as allosteric regulators of Pak1 and suggest that Pak1 is a "coincidence detector" whose activation depends on GTPases present in phosphoinositide-rich membranes. These findings expand the role of phosphoinositides in kinase signaling and suggest how altered phosphoinositide metabolism may upregulate Pak1 activity in cancer cells.

RESUMO

Protein microarrays are miniaturized multiplex assays that exhibit many advantages over the commonly used enzyme-linked immunosorbent assay (ELISA). This article aims to introduce protein microarrays to readers of Brain, Behavior, and Immunity and demonstrate its utility and validity for use in psychoneuroimmunological research. As part of an ongoing investigation of psychological and behavioral influences on influenza vaccination responses, we optimized a novel protein microarray to quantify influenza-specific antibody levels in human sera. Reproducibility was assessed by calculating intra- and inter-assay coefficients of variance on serially diluted human IgG concentrations. A random selection of samples was analyzed by microarray and ELISA to establish validity of the assay. For IgG concentrations, intra-assay and inter-assay precision profiles demonstrated a mean coefficient of variance of 6.7% and 11.5% respectively. Significant correlations were observed between microarray and ELISA for all antigens, demonstrating the microarray is a valid alternative to ELISA. Protein microarrays are a highly robust, novel assay method that could be of significant benefit for researchers working in psychoneuroimmunology. They offer high throughput, fewer resources per analyte and can examine concurrent neuro-immune-endocrine mechanisms.

RESUMO

This study examined cross-national similarities in a developmental model linking early age of alcohol use onset to frequent drinking and heavy drinking and alcohol problems 1 and 2 years later in a binational sample of 13-year-old students from two states: Washington State, USA and Victoria, Australia (N = 1833). A range of individual, family, school, and peer influences was included in analyses to investigate their unique and shared contribution to development of early and more serious forms of alcohol use and harms from misuse. Data were collected annually over a 3-year period from ages 13 to 15. Analyses were conducted using multiple-group structural equation modeling. For both states, early use of alcohol predicted frequent drinking, which predicted alcohol problems. Family protective influences had neither direct effects on heavy drinking nor effects on alcohol harm in either state, whereas school protection directly reduced the risk of heavy drinking in both states. Exposure to antisocial peers and siblings predicted a higher likelihood of heavy drinking and alcohol harm for students in both Washington and Victoria. Implications for the prevention of adolescent alcohol problems are discussed.

RESUMO

The enzyme CTP synthase (CTPS) dynamically assembles into macromolecular filaments in bacteria, yeast, Drosophila, and mammalian cells, but the role of this morphological reorganization in regulating CTPS activity is controversial. During Drosophila oogenesis, CTPS filaments are transiently apparent in ovarian germline cells during a period of intense genomic endoreplication and stockpiling of ribosomal RNA. Here, we demonstrate that CTPS filaments are catalytically active and that their assembly is regulated by the non-receptor tyrosine kinase DAck, the Drosophila homologue of mammalian Ack1 (activated cdc42-associated kinase 1), which we find also localizes to CTPS filaments. Egg chambers from flies deficient in DAck or lacking DAck catalytic activity exhibit disrupted CTPS filament architecture and morphological defects that correlate with reduced fertility. Furthermore, ovaries from these flies exhibit reduced levels of total RNA, suggesting that DAck may regulate CTP synthase activity. These findings highlight an unexpected function for DAck and provide insight into a novel pathway for the developmental control of an essential metabolic pathway governing nucleotide biosynthesis.

RESUMO

AIMS: This study examines gender differences in the pathway from childhood sexual abuse (CSA) to adult binge drinking. METHODS: Using longitudinal data on 313 males and females (31-41 years old, mean = 36.21) in the Lehigh Longitudinal Study, we test for gender differences in the pathway from CSA to adolescent drinking, norms and pro-alcohol peers, to adult binge drinking. RESULTS: Controlling for family history of alcohol problems, socioeconomic status (SES) and ethnicity, we found that for females there was a significant direct effect of CSA on adult binge drinking. For males there was no significant direct or indirect effect. Significant effects of family alcohol problems and SES were also moderated by gender. CONCLUSION: There are gender differences in the impact of CSA on adult binge drinking. Service providers and program developers should pay special attention to the possibility that their female clients may have a history of sexual abuse which could have implications for the course of prevention and treatment services related to binge drinking. Early intervention could prevent alcohol-related risk in adolescence which in turn could reduce, but not eliminate, the binge drinking consequences of CSA for females.

RESUMO

Adolescent depressed mood is related to the development of subsequent mental health problems, and family problems have been linked to adolescent depression. Longitudinal research on adolescent depressed mood is needed to establish the unique impact of family problems independent of other potential drivers. This study tested the extent to which family conflict exacerbates depressed mood during adolescence, independent of changes in depressed mood over time, academic performance, bullying victimization, negative cognitive style, and gender. Students (13 years old) participated in a three-wave bi-national study (n = 961 from the State of Washington, United States, n = 981 from Victoria, Australia; 98 % retention, 51 % female in each sample). The model was cross-lagged and controlled for the autocorrelation of depressed mood, negative cognitive style, academic failure, and bullying victimization. Family conflict partially predicted changes in depressed mood independent of changes in depressed mood over time and the other controls. There was also evidence that family conflict and adolescent depressed mood are reciprocally related over time. The findings were closely replicated across the two samples. The study identifies potential points of intervention to interrupt the progression of depressed mood in early to middle adolescence.

RESUMO

BACKGROUND: Children's exposure to violence increases their risk for later victimisation and perpetration of intimate partner violence (IPV). However, the relative influence of child abuse, adolescent violence, peer approval of violence and pro-violence attitudes on later IPV is not well established. AIMS: Analyses focus on the prediction of adult IPV from variables measured in childhood and adolescence to establish the unique influence of earlier victimisation and perpetration of violence, as well as other variables grounded in theory and empirical findings. METHODS: Data are from a longitudinal study that began in the 1970s with a sample of 457 preschool-aged children who were reassessed as adults. Outcomes of adult IPV victimisation and perpetration types were regressed on predictors of parent-reported child abuse, officially recorded child maltreatment, adolescent victimisation, violence perpetration, pro-violence attitudes and peer approval of violence during adolescence, controlling for childhood Socio Economic Status (SES), age in adolescence and gender. RESULTS: Dating violence victimisation and peer approval of dating violence in adolescence emerged as the unique predictors of IPV victimisation and perpetration in adulthood. Official child maltreatment predicted IPV perpetration. CONCLUSIONS: Results underscore the importance of prevention programmes and strategies to disrupt the cycle of violence at its early stages, as well as interventions during adolescence targeting peer influences.

RESUMO

This article reviews developmental studies of creativity in children and adolescents with a focus on "peaks" and "slumps" that have often been described in the literature. The irregularity of the development of creativity is interpreted in light of conceptual and measurement issues and with regard to the interaction between individual-level resources, task-specific demands, and environmental influences, resulting in apparent individual differences in the development of creativity. The need for longitudinal designs, multidimensional and multi-domain assessment of creative potential limiting the contribution of task-specific factors is outlined and discussed as an important direction for developmental research on creativity.

RESUMO

Autoimmunity may contribute to the pathogenesis of chronic obstructive pulmonary disease (COPD). Studies have identified disease-specific autoantibodies (DSAAbs) in COPD patients, but natural autoantibodies (NAAbs) may also play a role. Previous studies have concentrated on circulating autoantibodies, but lung-associated autoantibodies may be most important. Our aim was to investigate NAAbs and DSAAbs in the circulation and lungs of COPD smoking (CS) patients compared to smokers (S) without airway obstruction and subjects who have never smoked (NS). Immunoglobulin (Ig)G antibodies that bind to lung tissue components were significantly lower in the circulation of CS patients than NS (with intermediate levels in S), as detected by enzyme-linked immunosorbent assay (ELISA). The levels of antibodies to collagen-1 (the major lung collagen) detected by ELISA were also reduced significantly in CS patients' sera compared to NS. The detection of these antibodies in NS subjects indicates that they are NAAbs. The occurrence of DSAAbs in some CS patients and S subjects was indicated by high levels of serum IgG antibodies to cytokeratin-18 and collagen-5; furthermore, antibodies to collagen-5 eluted from homogenized lung tissue exposed to low pH (0·1 M glycine, pH 2·8) were raised significantly in CS compared to S and NS. Thus, this study supports a role in COPD for both NAAbs and DSAAbs.

RESUMO

OBJECTIVES: We examined the longitudinal effect of schools' drug policies on student marijuana use. METHODS: We used data from the International Youth Development Study, which surveyed state-representative samples of students from Victoria, Australia, and Washington State. In wave 1 (2002), students in grades 7 and 9 (n = 3264) and a school administrator from each participating school (n = 188) reported on school drug policies. In wave 2 (2003), students reported on their marijuana use. We assessed associations between student-reported and administrator-reported policy and student self-reported marijuana use 1 year later. RESULTS: Likelihood of student marijuana use was higher in schools in which administrators reported using out-of-school suspension and students reported low policy enforcement. Student marijuana use was less likely where students reported receiving abstinence messages at school and students violating school policy were counseled about the dangers of marijuana use. CONCLUSIONS: Schools may reduce student marijuana use by delivering abstinence messages, enforcing nonuse policies, and adopting a remedial approach to policy violations rather than use of suspensions.
