RESUMO
This study examined the roles of neighborhood social cohesion, adverse childhood experiences (ACEs), and parenting stress in early childhood on child behavioral outcomes in middle childhood and adolescence among socioeconomically disadvantaged Black families. To test a model linking perceptions of neighborhood social cohesion, single mothers' parenting stress, ACEs, and behavior problems in middle childhood and adolescence. We used four waves of longitudinal data from a subsample of 800 unmarried Black mothers and their children (at child birth and ages 3, 5, 9, and 15) from the Future of Families and Child Wellbeing Study, a nationally representative data set. Structural equation modeling with latent variables was used to measure direct and indirect effects. Mothers' perceptions of neighborhood social cohesion were significantly and negatively associated parenting stress (ß = -0.34, p < 0.05); parenting stress was significantly and positively related to adverse childhood experiences (ß = 0.40, p < 0.05) and behavior problems (ß = 0.32, p < 0.05); Adverse childhood experiences were significantly and positively related to behavior problems (ß = 0.26, p < 0.05); and behavior problems were indirectly influenced by neighborhood social cohesion through adverse childhood experiences (ß = -0.14, p < 0.05) and parenting stress (ß = 0.10, p < 0.05). Neighborhood factors may play a significant role in parenting stress, adverse childhood experiences in early childhood, and children's behavior problems in middle childhood and adolescence among some single mothers and children in economically and socially disadvantaged Black families. Interventions that enhance neighborhood social cohesion and foster supportive interactions among community members and organizations are recommended.

This report describes the recruitment of a sample of older African American women to test the effectiveness of an educational HIV prevention intervention that sought to reduce depressive symptoms and thereby HIV risks in this population. The outreach venue is the Black church. A framework for maximizing response is suggested. Of 62 women who participated in two arms of the intervention, 29 were assigned randomly to a four-session discussion group (experimental condition) and 33 were assigned to a one-session informational group (control condition) focused on HIV prevention education. Between-within subjects analyses of variance showed that participation in the study was associated with a significant improvement in the women's psychological status, i.e., decreased depressive symptoms. This change in depressive symptoms was due in part to the experimental condition assignment. Implications for future HIV prevention interventions, research, and methods used to maximize the probability of response among older African American women are discussed.
RESUMO
BACKGROUND: We previously reported relatively normal pulmonary function (2 years of age) and computed tomography (CT, 1 year of age) in cystic fibrosis (CF) newborn screened (NBS) infants. We now report follow up of these children to preschool age. METHODS: 67 NBS children with CF and 41 healthy controls underwent pulmonary function tests in infancy (â¼3 months, 1 year and 2 years) and at preschool (3-6 years). Broncho-alveolar lavage (BAL) and CT were undertaken in those with CF at 1 year. Primary outcomes at preschool were lung clearance index (LCI) and forced expired volume (FEV0.75). Risk factors for lung function impairment were identified by regression modelling, emphasising factors that could be identified or measured in the first 2 years of life. RESULTS: At preschool age children with CF had poorer lung function than controls, mean(95% CI) difference in LCI z-score: 1.47(0.96;1.97) and FEV0.75 z-score -0.54(-0.98; -0.10). Isolation of Pseudomonas aeruginosa before 6 months was a highly significant predictor of raised (abnormal) preschool LCI, associated with a mean (95%CI) increase of 1.69(0.43, 2.95) z-scores, compared to those with no Pseudomonas aeruginosa during the first 2 years of life. Including 2 year LCI and 1 year CT data in the predictive model increased the r2 from 13% to 61%. CONCLUSIONS: Lung function deteriorates after 2 years in NBS children with CF. Isolation of Pseudomonas aeruginosa before 6 months and minor abnormalities of infant lung function tests and CT in infancy are associated with higher preschool LCI.

BACKGROUND: Adverse childhood experiences (ACEs) in early childhood and developmental outcomes during the middle childhood and adolescent years have been understudied among low-income Black families. OBJECTIVE: To test a model linking economic hardship, single mothers' parenting stress, ACEs, and nonresident fathers' involvement in early childhood to behavior problems in middle childhood and adolescence. PARTICIPANTS AND SETTING: We used six waves of longitudinal data from a subsample of 800 unmarried Black mothers, nonresident fathers, and their children (at child birth and ages 1, 3, 5, 9, and 15) from the Fragile Families and Child Wellbeing Study, a nationally representative data set. METHOD: Structural equation models with latent variables that incorporate path analysis and confirmatory factor analysis were tested. RESULTS: Mothers' economic hardship was associated directly with parenting stress (beta = 0.27, p < .001) and related both directly (beta = 0.22, p < .001) and indirectly (through parenting stress) to the children's increased likelihood of exposure to ACEs (indirect effect = 0.05, p < .001). Nonresident fathers' involvement early on (child's age 1 to 5) was associated directly with reductions in the mothers' economic hardship (beta = -0.18, p < .001), children's reduced exposure to ACEs (beta = -0.15, p < .001), and fewer behavior problems in middle childhood and adolescence (beta = -0.10, p < .001). CONCLUSION: Nonresident Black fathers' involvement in single-mother families may buffer the adverse consequences over time for economically and socially disadvantaged Black children of exposure to ACEs in early childhood. Interventions that encourage sustained involvement by nonresident Black fathers with young children and their single mothers are recommended.

Objective: The current study sought to test the effect of an HIV prevention intervention on depressive symptoms in a sample of older African American women. Design Setting and Participants: A pretest-posttest randomized control group design was conducted in a mega-church in Los Angeles with a sample of 62 older African American women, aged ≥50 years, 29 of whom were randomly assigned to the experimental condition and 33 to the comparison/control condition. Measures: A measure of psychological wellbeing (CES-D) was utilized to test the effect of the four-session group intervention vs the one-session informational group intervention on change in depressive symptoms from pretest to posttest. Demographic characteristics included: measures of age in years; relationship and employment statuses (coded 1 for yes, 0 for no); and educational attainment. Results: Participation in the study was associated with a significant improvement in the women's psychological wellbeing from baseline to time 2; ie, decreased depressive symptoms. This change was greater for women in the four-session experimental group than for those in the one-session comparison group, due in part to a marginally significant interaction between time and experimental conditions. Conclusions: This study demonstrates the utility of faith-based/behavioral-scientist partnerships in HIV programming. Findings contribute to the evidence on interventions that might reduce depressive symptoms and HIV risk among older African American women.

BACKGROUND: Adverse childhood experiences (ACEs) are an identified risk factor for the social and emotional development of children. What is less known is the long-term effects of ACEs when poverty and ACEs coincide. OBJECTIVE: Using longitudinal cohort-panel data, we examined whether exposure to ACEs by the age of three among poor children would longitudinally result in behavioral problems at ages three, five, nine, and 15, after controlling for mothers' socioeconomic status and their children's characteristics. PARTICIPANTS AND SETTING: We used a subsample of 2750 children and their parents living in urban poverty from the Fragile Families and Child Wellbeing study. METHODS: Logistic regression modeling was used to obtain adjusted odds ratios of ACE categories predicting behavioral problems after accounting for family socioeconomic position. RESULTS: Our findings indicate that experiencing ACEs in early childhood was significantly associated with later behavioral outcomes from childhood to adolescence. Exposure to multiple ACEs before the age of three was significantly associated with the top-risk behavior group at age five; the odd ratios were 2.0 (CI = 1.3-3.1) and 2.9 (CI = 1.8-4.6) for two ACEs and three or more ACEs, respectively. At both ages nine and 15, children experiencing two or more ACEs had 1.9 to 3.2 times higher odds to demonstrate more the top 10th percentile of behavioral problems. Among covariates, mothers' race and education, and children's gender and temperament were identified as significant factors to determine behavior problems. CONCLUSIONS: The findings support policies and programs for families with children who have experienced economic disadvantages and early childhood adversity.

The diagnosis of asthma is currently based on clinical history, physical examination and lung function, and to date, there are no accurate objective tests either to confirm the diagnosis or to discriminate between different types of asthma. This consensus exercise reviews the state of the art in asthma diagnosis to identify opportunities for future investment based on the likelihood of their successful development, potential for widespread adoption and their perceived impact on asthma patients. Using a two-stage e-Delphi process and a summarizing workshop, a group of European asthma experts including health professionals, researchers, people with asthma and industry representatives ranked the potential impact of research investment in each technique or tool for asthma diagnosis and monitoring. After a systematic review of the literature, 21 statements were extracted and were subject of the two-stage Delphi process. Eleven statements were scored 3 or more and were further discussed and ranked in a face-to-face workshop. The three most important diagnostic/predictive tools ranked were as follows: "New biological markers of asthma (eg genomics, proteomics and metabolomics) as a tool for diagnosis and/or monitoring," "Prediction of future asthma in preschool children with reasonable accuracy" and "Tools to measure volatile organic compounds (VOCs) in exhaled breath."

DNA topoisomerase IIα (Topo IIα) ensures genomic integrity and unaltered chromosome inheritance and serves as a major target of several anticancer drugs. Topo IIα function is well understood, but how its expression is regulated remains unclear. Here, we identify the E3 ubiquitin ligase Smurf2 as a physiologic regulator of Topo IIα levels. Smurf2 physically interacted with Topo IIα and modified its ubiquitination status to protect Topo IIα from the proteasomal degradation in dose- and catalytically dependent manners. Smurf2-depleted cells exhibited a reduced ability to resolve DNA catenanes and pathological chromatin bridges formed during mitosis, a trait of Topo IIα-deficient cells and a hallmark of chromosome instability. Introducing Topo IIα into Smurf2-depleted cells rescued this phenomenon. Smurf2 was a determinant of Topo IIα protein levels in normal and cancer cells and tissues, and its levels affected cell sensitivity to the Topo II-targeting drug etoposide. Our results identified Smurf2 as an essential regulator of Topo IIα, providing novel insights into its control and into the suggested tumor-suppressor functions of Smurf2.

OBJECTIVE: This study examined the effects of a depression care quality improvement (QI) intervention implemented by using Community Engagement and Planning (CEP), which supports collaboration across health and community-based agencies, or Resources for Services (RS), which provides technical assistance, on training participation and service delivery by primarily unlicensed, racially and ethnically diverse case managers in two low-income communities in Los Angeles. METHODS: The study was a cluster-randomized trial with program-level assignment to CEP or RS for implementation of a QI initiative for providing training for depression care. Staff with patient contact in 84 health and community-based programs that were eligible for the provider outcomes substudy were invited to participate in training and to complete baseline and one-year follow-up surveys; 117 case managers (N=59, RS; N=58, CEP) from 52 programs completed follow-up. Primary outcomes were time spent providing services in community settings and use of depression case management and problem-solving practices. Secondary outcomes were depression knowledge and attitudes and perceived system barriers. RESULTS: CEP case managers had greater participation in depression training, spent more time providing services in community settings, and used more problem-solving therapeutic approaches compared with RS case managers (p<.05). CONCLUSIONS: Training participation, time spent providing services in community settings, and use of problem-solving skills among primarily unlicensed, racially and ethnically diverse case managers were greater in programs that used CEP rather than RS to implement depression care QI, suggesting that CEP offers a model for including case managers in communitywide depression care improvement efforts.

RESUMO
There are no European recommendations on issues specifically related to lung transplantation (LTX) in cystic fibrosis (CF). The main goal of this paper is to provide CF care team members with clinically relevant CF-specific information on all aspects of LTX, highlighting areas of consensus and controversy throughout Europe. Bilateral lung transplantation has been shown to be an important therapeutic option for end-stage CF pulmonary disease. Transplant function and patient survival after transplantation are better than in most other indications for this procedure. Attention though has to be paid to pretransplant morbidity, time for referral, evaluation, indication, and contraindication in children and in adults. This review makes extensive use of specific evidence in the field of lung transplantation in CF patients and addresses all issues of practical importance. The requirements of pre-, peri-, and postoperative management are discussed in detail including bridging to transplant and postoperative complications, immune suppression, chronic allograft dysfunction, infection, and malignancies being the most important. Among the contributors to this guiding information are 19 members of the ECORN-CF project and other experts. The document is endorsed by the European Cystic Fibrosis Society and sponsored by the Christiane Herzog Foundation.

Multiple breath washout (MBW) is a sensitive technique that detects early airways disease. However in very young children, large equipment and physiological dead space relative to lung volumes may result in a higher Lung Clearance Index (LCI). We investigated whether alveolar LCI (aLCI) is a more sensitive index than standard LCI in children. MBW data-sets from children aged 0.1-10.7 years [97 healthy controls and 93 with cystic fibrosis (CF)] were analysed. LCI is traditionally calculated by dividing the cumulative expired volume (CEV) by functional residual capacity (FRC) after correcting for equipment dead space. aLCI was calculated similarly, but after correcting the CEV and FRC for Langley's physiological dead space. There was a significant correlation between LCI and aLCI in health (r(2): 0.993; p<0.0001) and disease (r(2): 0.984; p<0.0001). Sensitivity of both LCI and aLCI in detecting abnormal lung function in CF was 39% during infancy, which increased to 77% and 83% respectively in older children. However, the difference in sensitivity (aLCI vs. LCI) was not significant (p=0.36). We conclude that LCI is minimally affected by airway deadspace, or relative equipment deadspace, and is an appropriate measure of lung function in infancy.

The functional outcome in preschool severe wheezers with eosinophilic airway inflammation and increased reticular basement membrane (RBM) thickness is unknown. We investigated the relationship between airway pathology at age 2 yrs and lung function at age 4-6 yrs in previous severe wheezers. Severe wheezers previously investigated by endobronchial biopsy and healthy children aged 4-6 yrs were recruited. Lung clearance index (LCI), conducting zone ventilation inhomogeneity (S(cond)), acinar ventilation inhomogeneity by multiple-breath washout, plethysmographic-specific airway resistance and exhaled nitric oxide fraction (F(eNO)) were measured. Lung function was compared between wheezers and healthy controls, and in wheezers correlated with past RBM thickness and mucosal eosinophilia (EG2+ cells). 72 healthy controls and 28 previous severe wheezers were tested. Wheezers had significantly higher median LCI (6.8 versus 6.6; p=0.001) and S(cond) (0.046 versus 0.016; p<0.0005) than healthy controls. Past RBM thickness (r=0.474, p=0.047) and EG2+ cells (r=0.552, p=0.041) showed significant correlations with current F(eNO), but no correlations were seen between past RBM thickness and current lung function. RBM thickness and EG2+ cells at age 2 yrs show a significant positive association with F(eNO) at age 5 yrs. Although lung function was abnormal at age 5 yrs in severe wheezers, this did not correlate with past RBM thickness.

RATIONALE: High resolution computed tomography (HRCT) is a more sensitive tool for detecting early cystic fibrosis (CF) lung disease than either spirometry or plain radiography, but its relationship to other measures of lung function has not been established in young children. OBJECTIVES: (1) To assess whether the lung clearance index (LCI) derived from multiple breath inert-gas washout (MBW) is as effective as HRCT in identifying pulmonary abnormalities; and (2) explore the relationships between abnormalities detected by HRCT and by spirometry, plethysmography and MBW (collectively, LFTs) in young children with CF. METHODS: Children with CF underwent LFTs and volumetric HRCT on the same day. Healthy age-matched controls underwent identical LFTs without HRCT. Scans were anonymised, and scored using the Brody-II CT scoring system, to assess for presence and extent of bronchiectasis, airway wall thickening, mucus plugging, and parenchymal opacities. RESULTS: Assessments were undertaken in 60 children with CF (mean (SD) 7.8 (1.3 years) and 54 healthy controls (7.9 (1.2) y). Among children with CF, 84% (47/56) had abnormal LCI, 58% (27/47) abnormal plethysmographic lung volumes (FRC(pleth) or RV), 35% (21/60) abnormal sRaw and 47% (28/60) abnormal spirometry (FEV1 or FEF(25-75)); whereas HRCT scans were abnormal in 85% (51/60): median total Brody-II score: 9.5% (range 0-51%). Total CT score correlated more strongly with LCI (Spearman correlation = 0.77) than with spirometry (R = -0.43) or any other marker of lung function. Of the nine children with normal LCI, five had abnormalities on HRCT, whereas five children with normal HRCT had raised LCI. CONCLUSIONS: These results suggest that while LCI and HRCT have similar sensitivity to detect CF lung disease, complimentary information may be gained in individual patients.

Two waves of data from a sample of 89 poor and near-poor single black mothers and their preschool children were used to study the influences of parenting stress, physical discipline practices, and nonresident fathers' relations with their children on behavior problems in kindergarten. The results indicate that higher levels of parent stress, more frequent spanking, and less frequent father-child contact at time 1 were associated with increased teacher-reported behavior problems at time 2. In addition, more frequent contact between nonresident biological fathers and their children moderated the negative effect of harsh discipline by mothers on subsequent child behavior problems. Specifically, when contact with the father was low, maternal spanking resulted in elevated levels of behavior problems; with average contact, this negative effect of spanking was muted; and with high contact, spanking was not associated with increased behavior problems in kindergarten. The implications of these findings for future research and policy are discussed.
