Adolescent Girls Offered Alternatives to Commercial Sexual Exploitation: A Case Study from the Philippines

Background: Up to 2% of adolescents and young women are subjected to commercial sexual exploitation (CSE) in the Philippines, an economically poor country that earns considerable revenue from “sex tourists.” Earlier research, in the 1990s in Metro Manila, described the living conditions of adolescents whose CSE was influenced by family poverty, their so-called “sex work” becoming a major source of income for families left behind in rural and provincial areas of Luzon. Recent research (up to 2014) indicates that conditions for adolescents experiencing CSE have, if anything, worsened. Methods: Following the original study, the researchers were able to offer scholarships with funds from a Canadian charity, which enabled 84 girls to leave “sex work,” and return to high school. Results: Follow-up 18 years later showed that being able to return to normal life, was successful for at least 61 (73%) of the young women who researchers were able to trace. Conclusions: We advocate vigorous efforts to prevent the recruitment and trafficking of adolescents into commercial sexual exploitation, and extend our comments to recent Canadian policy initiatives for adolescents experiencing CSE, since our original study was based on a Canada-Philippines comparison. In advocating the ‘universal living wage’ solution for avoidance of CSE, we argue that demonstration projects such as this can be important exemplars for global policy development

ABSTRACT: Six mothers of asthmatic children with histories of non-bonding were treated with a therapy aimed at repairing the bond between them and their children. Four of the children were then briefly treated to repair the bond and two infants were not treated. Eighteen variables were studied before treatment, after the mother's treatment, and after the child's treatment. There was improvement in all 18 variables. Five children experienced complete or nearly total improvement in their breathing. The two infants had total remission of symptoms. This study is the fourth in a series that examines the relationship between maternal-infant bonding and pediatric asthma Since French and Alexander's 1941 article, linking pediatrie asthma to some impairment in the mother-child relationship, clinicians and researchers have been looking into the mother's impact on childhood asthma. In their seminal article, French and Alexander hypothesized that conflict around excessive, unresolved dependence upon the mother was responsible for the child's asthma and that fear of separation from her could trigger an asthma attack. These children were preoccupied with thoughts of maternal rejection, and the asthma attack itself was considered a suppressed cry for the mother. They further observed that maternal rejection is found as a recurrent theme in the life of the asthmatic and that the child feels a need of maternal care and protection. When the child does not achieve this basic nurturance, he reacts with clinging and insecurity. The theme of maternal rejection found supporters in most of the studies of psychological antecedents of childhood asthma. In reviews of this literature, Pennington cited several articles which identify overprotection in mothers of asthmatics. Pinkerton (1967) discerned three main groups of parental attitudes: over-protective, rejective, and ambivalent. In the same vein, Schwartz (1988) noted that Pennington (1992) summarized that "rejection of the asthmatic child by the mother has been a dominant theme in the findings of a majority of investigators who have studied asthma as a psychosomatic disease." Schwartz (1988) state

Secreted Protein Acidic and Rich in Cysteine Is a Matrix Scavenger Chaperone

Secreted Protein Acidic and Rich in Cysteine (SPARC) is one of the major non-structural proteins of the extracellular matrix (ECM) in remodeling tissues. The functional significance of SPARC is emphasized by its origin in the first multicellular organisms and its high degree of evolutionary conservation. Although SPARC has been shown to act as a critical modulator of ECM remodeling with profound effects on tissue physiology and architecture, no plausible molecular mechanism of its action has been proposed. In the present study, we demonstrate that SPARC mediates the disassembly and degradation of ECM networks by functioning as a matricellular chaperone. While it has low affinity to its targets inside the cells where the Ca2+ concentrations are low, high extracellular concentrations of Ca2+ activate binding to multiple ECM proteins, including collagens. We demonstrated that in vitro, this leads to the inhibition of collagen I fibrillogenesis and disassembly of pre-formed collagen I fibrils by SPARC at high Ca2+ concentrations. In cell culture, exogenous SPARC was internalized by the fibroblast cells in a time- and concentration-dependent manner. Pulse-chase assay further revealed that internalized SPARC is quickly released outside the cell, demonstrating that SPARC shuttles between the cell and ECM. Fluorescently labeled collagen I, fibronectin, vitronectin, and laminin were co-internalized with SPARC by fibroblasts, and semi-quantitative Western blot showed that SPARC mediates internalization of collagen I. Using a novel 3-dimentional model of fluorescent ECM networks pre-deposited by live fibroblasts, we demonstrated that degradation of ECM depends on the chaperone activity of SPARC. These results indicate that SPARC may represent a new class of scavenger chaperones, which mediate ECM degradation, remodeling and repair by disassembling ECM networks and shuttling ECM proteins into the cell. Further understanding of this mechanism may provide insight into the pathogenesis of matrix-associated disorders and lead to the novel treatment strategies

The formin INF2 regulates basolateral-to-apical transcytosis and lumen formation in association with Cdc42 and MAL2

Transcytosis is a widespread pathway for apical targeting in epithelial cells. MAL2, an essential protein of the machinery for apical transcytosis, functions by shuttling in vesicular carriers between the apical zone and the cell periphery. We have identified INF2, an atypical formin with actin polymerization and depolymerization activities, which is a binding partner of MAL2. MAL2-positive vesicular carriers associate with short actin filaments during transcytosis in a process requiring INF2. INF2 binds Cdc42 in a GTP-loaded-dependent manner. Cdc42 and INF2 regulate MAL2 dynamics and are necessary for apical transcytosis and the formation of lateral lumens in hepatoma HepG2 cells. INF2 and MAL2 are also essential for the formation of the central lumen in organotypic cultures of epithelial MDCK cells. Our results reveal a functional mechanism whereby Cdc42, INF2, and MAL2 are sequentially ordered in a pathway dedicated to the regulation of transcytosis and lumen formation. © 2010 Elsevier Inc.This work was supported by grants (BFU2006-01925, BFU2009-07886, and CONSOLIDER COAT CSD2009-00016) to M.A.A. from the Ministerio de Ciencia e Innovación (MICINN), Spain.

What Research Questions Should the Next Generation of Birth Cohort Studies Address? An International Delphi Study of Experts.

OBJECTIVE: Birth cohort studies (BCS) have generated a wealth of invaluable basic scientific and policy-relevant information on a wide range of issues in child health and development. This study sought to explore what research questions are currently a priority for the next generation of BCS using a 3-round Delphi survey of interdisciplinary experts. METHODS: Twenty-four (Round I, N = 17; Round II, N = 21; Round III, N = 18) experts across a wide range of fields (eg, psychology, public health, and maternal/child health) agreed to participate. In Round I, the expert panel was invited to freely respond to the question, "what are the key scientific questions future birth cohort studies should address?" Content analysis of answers was used to identify 47 questions for rating on perceived importance by the panel in Round II and consensus-achieving questions were identified. Questions that did not reach consensus in Round II were posed again for expert re-rating in Round III. RESULTS: Twenty six of 47 questions reached consensus in Round II, with an additional 6 reaching consensus in Round III. Consensus-achieving questions rated highly on importance spanned a number of topics, including environmental effects on child development, intergenerational transmission of disadvantage, and designing BCS to inform intervention strategies. CONCLUSION: Investigating the effects of family/environmental factors and social disadvantage on a child's development should be prioritized in designing future BCS. The panel also recommended that future BCS are designed to inform intervention strategies

Evidence for Better Lives Study: a comparative birth-cohort study on child exposure to violence and other adversities in eight low- and middle-income countries - foundational research (study protocol)

Its effects begin at prenatal stages with long-lasting impacts on later health and well-being. The Evidence for Better Lives Study (EBLS) aims to produce high-quality longitudinal data from cities in eight low- and middle-income countries—Ghana, Jamaica, Pakistan, the Philippines, Romania, South Africa, Sri Lanka and Vietnam—to support effective intervention to reduce violence against children. EBLS-Foundational Research (EBLS-FR) tests critical aspects of the planned EBLS, including participant recruitment and retention, data collection and analysis. Alongside epidemiological estimates of levels and predictors of exposure to violence and adversity during pregnancy, we plan to explore mechanisms that may link exposure to violence to mothers’ biological stress markers and subjective well-being. Methods and analyses: EBLS-FR is a short longitudinal study with a sample of 1200 pregnant women. Data are collected during the last trimester of pregnancy and 2 to 6 months after birth. The questionnaire for participating women has been translated into nine languages. Measures obtained from mothers will include, among others, mental and physical health, attitudes to corporal punishment, adverse childhood experiences, prenatal intimate partner violence, substance use and social/community support. Hair and dry blood spot samples are collected from the pregnant women to measure stress markers. To explore research participation among fathers, EBLS-FR is recruiting 300 fathers in the Philippines and Sri Lanka. Ethics and dissemination: The study received ethical approvals at all recruiting sites and universities in the project. Results will be disseminated through journal publications, conferences and seminar presentations involving local communities, health services and other stakeholders. Findings from this work will help to adjust the subsequent stages of the EBLS project

Characterization of anti-NF-κB RNA aptamer-binding specificity in vitro and in the yeast three-hybrid system

RNA aptamers offer a potential therapeutic approach to the competitive inhibition of DNA-binding transcription factors. In previous reports we described in vitro selection and characterization of anti-NF-κB p50 and p65 RNA aptamers. We now describe the further characterization of these aptamers in vitro and in vivo. We show that sub-saturating concentrations of certain anti-p50 RNA aptamers promote complex formation with NF-κB p50 tetramers, whereas anti-p65 R1 RNA aptamers bind NF-κB dimers under all conditions tested. Yeast three-hybrid RNA aptamer specificity studies corroborate previous in vitro results, verifying that anti-p50 and anti-p65 R1 RNA aptamers are highly specific for NF-κB p502 and p652, respectively. These studies introduce a novel T-cassette RNA transcript that improves RNA display from a four-way RNA junction. Mutagenesis of the anti-p65 R1 aptamer reveals tolerated substitutions, suggesting a complex tertiary structure. We describe in vivo selections from a yeast three-hybrid RNA library containing sequences present early in the R1 SELEX process to identify novel anti-p65 RNA aptamers, termed Y1 and Y3. These aptamers appear to be compact bulged hairpins, reminiscent of anti-p50. Y1 competitively inhibits the DNA-binding domain of NF-κB p652 in vitro

Measuring antenatal depressive symptoms across the world:A validation and cross-country invariance analysis of the patient health questionnaire-9 (PHQ-9) in eight diverse low-resource settings

Measures that produce valid and reliable antenatal depressive symptom scores in low-resource country contexts are important for efforts to illuminate risk factors, outcomes, and effective interventions in these contexts. Establishing the psychometric comparability of scores across countries also facilitates analyses of similarities and differences across contexts. To date, however, few studies have evaluated the psychometric properties and comparability of the most widely used antenatal depressive symptom measures across diverse cultural, political, and social contexts. To address this gap, we used data from the Evidence for Better Lives Study—Foundational Research (EBLS-FR) project to examine the internal consistency reliability, nomological network validity, and cross-country measurement invariance of the nine-item version of the Patient Health Questionnaire (PHQ-9) in antenatal samples across eight low-resource contexts. We found that the PHQ-9 scores had good internal consistency across all eight countries. Correlations between PHQ-9 scores and constructs conceptually associated with depression were generally consistent, with a few exceptions. In measurement invariance analyses, only partial metric invariance held and only across four of the countries. Our results suggest that the PHQ-9 yields internally consistent scores when administered in culturally diverse antenatal populations; however, the meaning of the scores may vary. Thus, interpretation of PHQ-9 scores should consider local meanings of symptoms of depression to ensure that context-specific conceptualizations and manifestations of antenatal depressive symptoms are adequately reflected.</p
