RESUMO
PURPOSE: Although there is a growing evidence base on the drivers of child marriage, comparatively little is known about the experiences of married girls in refugee settings and how their development trajectories diverge from those of their nonmarried peers, particularly in the context of the COVID-19 pandemic. Drawing on cross-national panel data from Bangladesh and Jordan, this article explores diversity in child marriage experiences in contexts affected by forced displacement, highlighting how married girls' well-being differs from that of their unmarried peers, and how COVID-19 has reinforced these differences. METHODS: We analyzed longitudinal survey data-collected pre- and post-COVID-19-from the Gender and Adolescence: Global Evidence study with 293 ever-married and 1,102 never-married adolescent girls. Multivariate regression analysis assessed the well-being of married and unmarried girls across contexts and refugee status, both prior to and during the COVID-19 pandemic. These quantitative data are complemented by in-depth qualitative data from adolescents (n = 112), and key informant interviews with service providers and community leaders (n = 62). RESULTS: Our findings highlight that married girls in contexts affected by displacement are disadvantaged in multiple ways, but that the patterning of disadvantage varies across contexts, and that marriage can also have protective effects in certain contexts. The COVID-19 pandemic has, however, served to exacerbate existing inequalities in all contexts. DISCUSSION: Although child marriage prevention efforts remain critical, there is also an urgent need for programming that targets married girls in refugee and host communities to mitigate negative outcomes among this vulnerable group.

Over the past 25 years, tremendous progress has been made in increasing the evidence on child marriage and putting it to good use to reduce the prevalence of child marriage and provide support to married girls. However, there is still much to be done to achieve the Sustainable Development Goal target 5.3 of ending child marriage by 2030, and to meet the needs of the 12 million girls who are still married before age 18 each year. To guide and stimulate future efforts, the UNDP-UNFPA-UNICEF-WHO-World Bank Special Programme of Research, Development and Research Training in Human Reproduction, the World Health Organization, the UNICEF-UNFPA Global Programme to End Child Marriage, and Girls Not Brides: The Global Partnership to End Child Marriage convened an expert group meeting in 2019 to: (1) review the progress made in building the evidence base on child marriage since the publication of research priorities in this area in 2015, (2) identify an updated set of research priorities for the next ten years, and (3) discuss how best to support research coordination, translation, and uptake. This article provides a summary of the progress made in this area since 2015 and lists an updated set of research gaps and their rationale in four key areas: (1) prevalence, trends, determinants, and correlates of child marriage; (2) consequences of child marriage; (3) intervention effectiveness studies to prevent child marriage and support married girls; and (4) implementation research studies to prevent child marriage and support married girls. It also highlights a number of calls-to-action around research coordination and knowledge translation to support the emerging and evolving needs of the field.
RéSUMé: Au cours des 25 dernières années, d'énormes progrès ont été réalisés pour mettre à jour les données concernant le mariage des enfants et les mettre à profit pour réduire la prévalence du mariage des enfants et apporter un soutien aux filles mariées. Cependant, il reste encore beaucoup à faire pour atteindre la cible 5.3 de l'Objectif de Développement Durable consistant à mettre fin au mariage des enfants d'ici 2030 et pour répondre aux besoins des 12 millions de filles qui sont encore mariées avant l'âge de 18 ans chaque année. Guider et stimuler les efforts futurs, tel est le Programme Spécial de Recherche de la Banque Mondiale PNUD-FNUAP-UNICEF-OMS, du Développement et la Formation à la Recherche en Reproduction Humaine, de l'Organisation Mondiale de la Santé, du Programme Mondial UNICEF-FNUAP pour mettre fin au mariage des enfants et « Des filles pas des Mariées ¼ : le Partenariat Mondial pour mettre fin au mariage des enfants a convoqué une réunion de groupe d'experts en 2019 pour : 1. passer en revue les progrès accomplis dans la constitution de la base de données factuelles sur le mariage des enfants depuis la publication des priorités de la recherche dans ce domaine en 2015, 2. identifier un ensemble actualisé de priorités de recherche pour les dix prochaines années, et 3. discuter de la meilleure façon de soutenir la coordination, la traduction et la compréhension de la recherche. Cet article résume les progrès réalisés dans ce domaine depuis 2015 et répertorie sous forme de mise à jour un ensemble de lacunes dans la recherche et leur justification dans quatre domaines clés: 1) prévalence, tendances, déterminants et corrélatifs du mariage des enfants; 2) conséquences du mariage des enfants; 3) études ayant trait à l'efficacité des interventions pour prévenir le mariage des enfants et soutenir les filles mariées; et 4) études de recherche sur la mise en Åuvre pour prévenir le mariage des enfants et soutenir les filles mariées. Il met également en évidence un certain nombre d'appels à l'action autour de la coordination de la recherche et de l'application des connaissances pour répondre aux besoins émergents et à l'évolution de ce domaine.
RESUMEN: En los últimos 25 años se ha avanzado enormemente y existe ahora más evidencia sobre el matrimonio infantil, y sobre como se debe poner la evidencia en práctica para reducir la prevalencia del matrimonio infantil y proporcionar apoyo a las niñas casadas. Sin embargo, aún queda mucho por hacer para alcanzar la meta 5.3 de los Objetivos de Desarrollo Sostenible de poner fin al matrimonio infantil para 2030, y para satisfacer las necesidades de los 12 millones de niñas que cada año se casan antes de los 18 años. Para orientar y estimular los esfuerzos futuros, el Programa Especial de Investigación, Desarrollo y Formación de Investigadores en Reproducción Humana del PNUD-FNUAP-UNICEF-OMS-Banco Mundial, la Organización Mundial de la Salud, el Programa Mundial para la Eliminación del Matrimonio Infantil de UNICEF-FNUAP y Girls Not Brides: La Alianza Mundial para Acabar con el Matrimonio Infantil convocó una reunión de un grupo de expertos en 2019 para: 1. Revisar los progresos realizados en la construcción de la base de evidencias sobre el matrimonio infantil desde la publicación de las prioridades de investigación en este ámbito en 2015, 2. Identificar un conjunto actualizado de prioridades de investigación para los próximos diez años, y 3. Debatir la mejor manera de apoyar la coordinación, la traducción y la aceptación de la investigación.Este artículo ofrece un resumen de los progresos realizados en este ámbito desde 2015 y enumera un conjunto actualizado de lagunas de investigación y su justificación en cuatro áreas clave: 1) prevalencia, tendencias, determinantes y correlaciones del matrimonio infantil; 2) consecuencias del matrimonio infantil; 3) estudios de eficacia de las intervenciones para prevenir el matrimonio infantil y apoyar a las niñas casadas; y 4) estudios de implementación para prevenir el matrimonio infantil y apoyar a las niñas casadas. También destaca una serie de llamados a la acción en torno a la coordinación de la investigación y la traducción de conocimientos para apoyar las necesidades emergentes y en evolución del campo.

PURPOSE: This review assesses evaluations published from 2000 to 2019 to shed light on what approaches work, especially at scale and sustainably, to prevent child marriage in low- and middle-income countries. METHODS: We conducted a search of electronic databases and gray literature and evaluated the methodological quality and risk of bias of included studies. RESULTS: A total of 30 studies met the inclusion criteria. Interventions that support girls' schooling through cash or in-kind transfers show the clearest pattern of success in preventing child marriage, with 8 of 10 medium-high quality studies showing positive results. Although limited in number, five studies on favorable job markets and targeted life skills and livelihoods training show consistent positive results. Comparatively, asset or cash transfers conditional on delaying marriage show success only among two of four evaluations, and the three studies on unconditional cash transfers for poverty mitigation show no effect. Findings also show a low success rate for multicomponent interventions with positive results in only one of eight medium-high quality studies. Further, single component interventions were much more likely to be at scale and sustainable than multicomponent interventions. CONCLUSIONS: These results indicate that enhancement of girls' own human capital and opportunities is the most compelling pathway to delaying marriage. In contrast, low rates of success, scale-up, and sustainability of multicomponent programs requires reconsideration of this approach.

Previous structural studies of osteoprotegerin (OPG), a crucial negative regulator of bone remodeling and osteoclastogenesis, were mostly limited to the N-terminal ligand-binding domains. It is now known that the three C-terminal domains of OPG also play essential roles in its function by mediating OPG dimerization, OPG-heparan sulfate (HS) interactions, and formation of the OPG-HS-receptor activator of nuclear factor κB ligand (RANKL) ternary complex. Employing hydrogen-deuterium exchange MS methods, here we investigated the structure of full-length OPG in complex with HS or RANKL in solution. Our data revealed two noteworthy aspects of the OPG structure. First, we found that the interconnection between the N- and C-terminal domains is much more rigid than previously thought, possibly because of hydrophobic interactions between the fourth cysteine-rich domain and the first death domain. Second, we observed that two hydrophobic clusters located in two separate C-terminal domains directly contribute to OPG dimerization, likely by forming a hydrophobic dimerization interface. Aided by site-directed mutagenesis, we further demonstrated that an intact dimerization interface is essential for the biological activity of OPG. Our study represents an important step toward deciphering the structure-function relationship of the full-length OPG protein.

A novel method has been developed for the easy measurement of heparin's anticoagulant activity using surface plasmon resonance. The anticoagulant activity of target heparin was evaluated by measuring the competitive antithrombin III binding of analyte heparin in the solution phase and USP heparin immobilized on chip surface. Heparins, obtained from different animal sources, and low molecular weight heparins were analyzed. The results were reproducible and correlated well with the results of chromogenic assays (correlation coefficient r = 0.98 for anti-Xa and r = 0.94 for anti-IIa). This protocol provides many advantages, significantly minimizing time, cost and the complications of chromogenic assay methods.

This article reviews 23 child marriage prevention programs carried out in low-income countries and employing a range of programmatic approaches and evaluation strategies. We document the types of child marriage programs that have been implemented, assess how they have been evaluated, describe the main limitations of these evaluations, summarize the evaluation results, and make recommendations to improve future prevention efforts. The evidence suggests that programs offering incentives and attempting to empower girls can be effective in preventing child marriage and can foster change relatively quickly. Methodological limitations of the reviewed studies, however, underscore that more needs to be learned about how the programs prevent child marriage and whether impact is sustained beyond program implementation.

This article examines how the sex composition of women's current children at the start of a pregnancy interval influences both fertility desires and the full range of reproductive actions women may take to realize them, including temporary contraception, abortion and sterilization, in Madhya Pradesh, India, where popular notions of ideal family size and sex composition are dominated by son preference. The analysis is conducted using a dataset of 9127 individual pregnancy intervals from a 2002 statewide representative survey of 2444 women aged 15-39 with at least one child. The results indicate that women's preferences go beyond a singular preference for male children, with the preferred composition of children being two boys and one girl. Women with this composition are 90% less likely to report having wanted another pregnancy (OR 0.097, p < 0.01) relative to those with two girls. These preferences have significant implications for reproductive actions. While sex composition has no statistically significant effect on the use of temporary contraception, those with the preferred sex composition are twice as likely to attempt abortion (OR 2.436, p < 0.01) and twelve times more likely to be sterilized (OR 12.297, p < 0.01) relative to those with two girls only.

This article examines the determinants of contraceptive and abortion behavior and how each of these influences the other, with an emphasis on the role of women's life-course stage and experience. We base our approach on life-course theory, which argues that behavior is influenced by current circumstances as well as experiences over the life course. We use data collected for every pregnancy experienced by 2,444 women in Madhya Pradesh, India, to explore use of temporary contraceptive methods (both modern and traditional) and sterilization, as well as abortion attempts. We use logistic regression to model whether women took these actions in a given pregnancy interval, including past experience with contraception in the abortion analyses and with abortion in the contraceptive analyses. The results suggest that life-course factors play a role in shaping behavior. Moreover, past use of contraceptives has a significant effect on attempted abortion and vice versa. Finally, we find that this relationship changes as women age and accumulate experience.

Primitive neuroectodermal tumors (PNETs) are malignant proliferations of small, undifferentiated neuroectodermal cells occurring mainly in children and share the same reciprocal translocation between chromosomes 11 and 22 and the same patterns of biochemical and oncogene expression as osseus and extraosseus Ewing's sarcoma. Some PNETs occur in the brain, while others (the peripheral PNETs) occur in sites outside the brain, such as in the extremities, pelvis and the chest wall. They mostly originate in the chest, pelvis and retroperitoneum; in rare cases, occurrence in the head and neck area has also been seen. We present a rare case of primitive neuroectodermal tumor arising in the prostate gland in a 25-year-old male. To the best of our knowledge, this is the first documentation of a primary peripheral primitive neuroectodermal tumor in the prostate gland of any patient from India and rarely reported in English literature.

There is a large amount of research into maternal health as a health issue, but maternal health as a development issue has been less explored. This Review analyses the evidence from the past 20 years on the links between maternal health and development to examine maternal health within a development framework. We note that although existing evidence suggests that these links are strong, further research is needed to definitively substantiate how and to what extent maternal health and development affect each other. Further, we find that progress and investment in maternal health have lagged far behind estimates of what is needed to achieve the Millennium Development Goals.
