Desire for fertility and associated factors among people living with HIV/AIDS (PLWHA) in selected antiretroviral therapy (ART) clinics of Horro Guduru Wollega Zone, North West Oromia, Ethiopia- A cross sectional study

Background: Most recently fertility issues in HIV positive men and women are becoming increasingly important. Because of ART access and its good life effect, it is expected that the need and desire to get married, to have children and to have sexual partners for PLWHA would change with the regard to reproductive health. In Ethiopia HIV positive individuals may or may not have desire to have children. And the extent of this desire and how it varies by individual, health and demographic characteristics is not well known.

Objective: the aim of the study was to assess desire for fertility and associated factors among PLWHA in selected ART clinics of Horro Guduru Wollega Zone, Oromia National Regional State, Ethiopia.

Methods: A cross-sectional, institutional-based study that employed quantitative and qualitative in-depth interviews was conducted. Three hundred twenty one study subjects were selected using systematic random sampling technique and the data was collected using interviewer administered structured questionnaire. Data entry and analysis were performed using EPI Info version 3.5.1 and SPSS version 16. P-value <0.05 was taken as statistically significant and logistic regression was used to control potential confounding factors.

Results: Seventy three (57.9%) of the males and seventy six (39%) of the females desired to have children, giving a total of 149(46.4%) of all study participants. PLWHA who desired children were younger (AOR:3.3, 95%CI: 1.3-8.9), married (AOR: 5.8, 95%CI: 2.7-12.8), had no children (AOR: 75, 95%CI: 20.1-273.3) and males (AOR; 1.9, 95%CI: 1.02-3.62) compared with their counter parts. The major reason for those people who did not desire children were having desired number of children 80 (46.5%) followed by fear of HIV transmission to child reported by 42 (24.4%) of them.

Conclusion: A considerable number of PLWHA wants to have a child currently or in the near future. Many variables like socio demography, partner related, number of alive children and HIV related disease condition were significantly associated with fertility desire.

As comunidades virtuais no Facebook no setor do vinho: estudo de caso

A Internet tem conseguido mudar os limites das interações sociais e económicas, por fornecer uma infraestrutura robusta para comunicação sem constrangimento de distâncias no tempo e no espaço, que pode ser usada em diversas formas para acumulação e arquivo de recursos de conhecimento. Esta revolução da Internet levou a uma difusão sem precedentes de comunidades virtuais em que os consumidores participam e expressam as suas opiniões sobre os produtos e serviços que consomem ou pretendem consumir. O presente trabalho pretende explorar a temática das comunidades virtuais como fator de inovação, tendo como base o estudo de caso de uma comunidade virtual ligada ao setor do vinho, procurando compreender até que ponto as comunidades virtuais podem contribuir para a evolução dos produtos ou mesmo para a criação de novos produtos. O trabalho inicia-se com a revisão da literatura em torno do conhecimento, internet, comunidades virtuais, lead users e o processo de inovação, crowdsourcing e a cocriação no processo de desenvolvimento de novos produtos. Conclui-se que as empresas podem construir estratégias que permitam uma canalização da informação proporcionada pelos consumidores e Lead Users, procurando, por exemplo, utilização de ferramentas de crowdsourcing. Segue-se a aplicação de uma estratégia de investigação qualitativa, o estudo de caso, à página no Facebook Vinhos do Alentejo, em que se analisa uma comunidade de consumidores de vinhos do Alentejo que proporciona ideias de melhoria do produto ou da experiência de consumo. A recolha dos dados dessa página e a análise de conteúdo foram apoiadas pelo NVivo 10. Como principais resultados destacam-se a utilização desta página como ferramenta de marketing, na divulgação dos vinhos, da gastronomia, da região do Alentejo e ainda a obtenção de experiências preferidas de consumo dos vinhos.

De touch: extending service channels in an airport through touch technologies

This project aimed to create a communication and interaction channel between Madeira Airport and its passengers. We used the pre-existent touch enabled screens at the terminal since their potential was not being utilised to their full capacity. To achieve our goal, we have followed an agile strategy to create a testable prototype and take advantages of its results. The developed prototype is based on a plugin architecture turning it into a maintainable and highly customisable system. The collected usage data suggests that we have achieved the initially defined goals. There is no doubt that this new interaction channel is an improvement regarding the provided services and, supported by the usage data, there is an opportunity to explore additional developments to the channel.

La transmission religieuse et culturelle au sein de familles maghrébo-québécoises à Montréal

Cette recherche porte sur la transmission religio-culturelle aux enfants de couples maghrébo-québécois islamo-chrétiens à Montréal. À la suite de l’analyse de 10 entrevues semi-directives réalisées auprès de couples parentaux, nous tenterons de répondre aux questions suivantes : Quelle appartenance religieuse les parents veulent-ils transmettre à leur(s) enfant(s) ? Comment se manifestent leurs choix dans leur pratique religieuse ? Quels compromis les parents font-ils pour l’équilibre familial et identitaire de leur(s) enfant(s) ? Comment légitiment-ils leurs choix parentaux ? Afin de répondre à ces questions, nous nous sommes donné les objectifs spécifiques suivants : 1) documenter les choix des parents concernant la transmission religio-culturelle aux enfants; 2) cerner les façons dont les pratiques et les croyances religieuses des parents influencent leurs choix; 3) expliquer en quoi ces choix se manifestent dans leurs pratiques rituelles avec les enfants; 4) dégager les légitimations que les parents font vis-à-vis de leur choix de transmission. Les résultats de notre recherche ne nous ont pas permis de trouver une logique de transmission qui s’applique à tous nos parents. Cependant, nous retenons que les enfants de notre échantillon sont identifiés par leurs parents soit comme musulmans (5 familles sur 10) soit sans religion (5 familles sur 10). Aucun couple n’a choisi, en effet, le catholicisme pour leur enfant, et ce, même dans le cas où le conjoint catholique est pratiquant. À l’aide des choix parentaux concernant plus particulièrement le rite de la circoncision et la célébration des principales fêtes religieuses, nous dégageons quelques points d’ancrages communs face à la transmission symbolique. Quelle que soit la position du parent musulman face à la religion (pratiquant, non pratiquant, athée), celui-ci reste profondément attaché au rite de la circoncision pour son enfant dans un souci de transmission culturelle. La transmission biculturelle où les fêtes des deux lignées sont célébrées en famille est la plus pratiquée.

Déterminants individuels et contextuels de la mortalité des enfants de moins de cinq ans en Afrique au sud du Sahara : analyse comparative des enquêtes démographiques et de santé

La santé des enfants demeure une question prioritaire en Afrique sub-saharienne. Les disparités en matière de mortalité entre pays et au sein des pays persistent et se sont fortement accrues durant la dernière décennie. En dépit de solides arguments théoriques voulant que les variables contextuelles soient des déterminants importants de la santé des enfants, ces facteurs, et particulièrement les influences du contexte local, ont été étudiées beaucoup moins souvent que les caractéristiques individuelles. L'objectif principal de la présente thèse est d’identifier les déterminants individuels et contextuels associés à la mortalité des enfants de moins de 5 ans en Afrique sub-saharienne. L’analyse systématique est basée sur les données les plus récentes des enquêtes démographiques et de santé (DHS/EDS). Deux questions spécifiques sont examinées dans cette thèse. La première évalue la mesure dans la quelle le contexte local affecte la mortalité infanto-juvénile, net des caractéristiques individuelles. La seconde question est consacrée à l’examen de l’effet du faible poids à la naissance sur le risque de décès avant 5 ans. Par rapport à la première question, les analyses multi-niveaux confirment pour plusieurs pays étudiés l’importance simultanée de l’environnement familial et du contexte local de résidence dans l’explication des différences de mortalité infanto-juvénile. Toutefois, par comparaison au contexte familial, l’ampleur de l’effet de l’environnement local paraît assez modeste. Il apparaît donc que le contexte familial reste un puissant déterminant de la mortalité des enfants de moins de 5 ans en Afrique sub-saharienne. Les résultats indiquent en outre que certains attributs du contexte local de résidence influencent le risque de décès des enfants avant 5 ans, au-delà des facteurs individuels dans plusieurs pays. Cette thèse confirme l’effet contextuel de l’éducation sur la mortalité des enfants. Cet effet s’ajoute, dans certains pays, à l'effet positif du niveau individuel d’éducation de la mère sur la survie de l'enfant. Les résultats montrent aussi que le degré d’homogénéité ethnique de la localité influence fortement la probabilité de mourir avant 5 ans dans certains pays. Globalement, les résultats de cette thèse suggèrent que le défi de réduire la mortalité des enfants va au-delà des stratégies visant uniquement les facteurs individuels, et nécessite une meilleure compréhension de l’influence des facteurs contextuels. Par rapport à la deuxième question, les résultats montrent également que les facteurs individuels restent aussi très importants dans l’explication des différences de mortalité des enfants dans plusieurs pays étudiés. Nos résultats indiquent que les différences de mortalité selon le poids à la naissance sont significatives dans tous les pays inclus dans l’analyse. Les enfants nés avec un faible poids (moins de 2500 grammes) courent presque 2 à 4 fois plus de risques de mourir au cours des cinq premières années de vie que les enfants de poids normal, même après correction pour l’hétérogénéité non observée. Ce résultat suggère qu’en plus des mesures visant à réduire la pauvreté et les inégalités de revenus, la réduction de l’incidence du faible poids à la naissance pourrait apporter une contribution majeure aux Objectifs du Millénaire pour le développement; spécialement comme une stratégie efficace pour réduire le niveau de mortalité parmi les enfants de moins de cinq ans.

L'engagement parental des mères et des pères : associations avec la relation coparentale et l'adaptation socio-affective à l'âge préscolaire

La majorité des études qui ont cherché à identifier les déterminants d’un développement harmonieux chez l’enfant ont considéré l’impact des variables maternelles ou paternelles sur ce dernier, mais rares sont celles qui ont tenu compte des deux parents, des influences et des interactions entre ceux-ci, ou même de la relation qu’ils entretiennent en tant que coparents. La présente recherche a pour objectif de pallier à ces faiblesses afin de mieux cerner les déterminants de l’engagement parental des mères et des pères, ainsi que de l’adaptation de l’enfant. Dans ce but, 70 familles (père, mère et enfant) ont été recrutées par l’intermédiaire de centres de la petite enfance (CPE) de la région de Montréal, pour former un échantillon qui comporte 38 garçons et 32 filles âgés de 34 à 70 mois. Les parents participants ont été visités à deux reprises par un assistant de recherche pour la complétion de questionnaires qui ont permis d’évaluer l’engagement parental, la relation coparentale et l’adaptation de l’enfant. On observe plusieurs relations significatives entre l’engagement parental et différentes dimensions de la relation coparentale, surtout dans les domaines traditionnellement réservés aux mères. La coparentalité et l’engagement parental apparaissent aussi reliés à la compétence sociale de l’enfant, mais pas à l’anxiété/retrait de ce dernier, ni à son agressivité/irritabilité. Des analyses de régression hiérarchique ont été effectuées afin d’expliquer la variance l’engagement parental par les caractéristiques de la relation coparentale, puis la variance de l’adaptation de l’enfant par la relation coparentale et l’engagement parental des mères et des pères. Ces analyses ont notamment permis de constater que certaines caractéristiques du père modèrent la relation entre les croyances parentales de la mère et la participation relative des deux parents au soutien émotionnel, aux jeux et à l’introduction de nouveauté. Elles ont également permis de cerner une relation de médiation, dans laquelle les croyances paternelles sont positivement associées à la chaleur paternelle, qui est elle-même positivement associée à la compétence sociale de l’enfant. La discussion met en évidence l’importance d’étudier l’engagement parental et l’adaptation de l’enfant dans un cadre systémique, qui s’intéresse à la fois aux caractéristiques des mères et des pères, à la relation entre les parents et aux influences que mère et père ont l’un sur l’autre.

Les mères avec un trouble de personnalité limite en protection de la jeunesse : un paradoxe entre les difficultés et les services

Une proportion significative de mères d’enfants pris en charge par la protection de la jeunesse souffrirait d’un trouble de personnalité limite (TPL). En effet, les difficultés parentales associées à ce trouble prédisposent davantage à des situations d’abus ou de négligence envers leurs enfants. Cependant, il existe peu d’information sur les difficultés et les besoins de ces mères dans ce contexte particulier. Cette étude qualitative a été réalisée auprès de 30 mères avec un TPL et dont au moins un enfant était suivi par le Centre jeunesse de Montréal-Institut universitaire. La présente étude a permis de mieux décrire les difficultés des mères en lien avec leur TPL, leurs enfants et leur situation conjugale. Leurs expériences des services en protection de la jeunesse ont révélé des suivis instables et peu adaptés à leurs difficultés. Les mères ont abordé l’importance des qualités relationnelles des intervenants à l’établissement d’une collaboration de la part des intervenants et l’importance de mettre en place des services spécifiquement dédiés aux parents. Il semblerait pertinent d’adapter les services de protection de la jeunesse afin d’inclure des interventions qui ciblent les difficultés spécifiques des parents qui ont un TPL, notamment en ce qui a trait à leurs habiletés parentales.

Niños a la escuela y no a la guerra: la Educación para la Paz como estrategia para la prevención del reclutamiento infantil. Caso de análisis: San Juan Nepomuceno, Montes de María. (2003 – 2014)

La presente investigación analiza los alcances y las limitaciones de cinco proyectos de Educación para la Paz desarrollados en la Escuela Normal Superior de San Juan Nepomuceno-Montes de María, en la prevención del reclutamiento y la utilización de niños, niñas y jóvenes por parte de grupos armados al margen de la ley. En ese sentido, se describe y explica de qué manera las estrategias pedagógicas orientadas hacia la enseñanza de derechos humanos, memoria histórica y resolución no violenta de conflictos pueden disminuir el riesgo de reclutamiento. Estos propósitos se resolvieron gracias a una revisión sistemática de documentos académicos e informes institucionales que se referían al objeto de estudio, y por medio del trabajo de campo realizado en San Juan Nepomuceno.

Parents' experiences of their children's presence in discussions with physicians about leukemia

OBJECTIVE: We aimed to examine parents' views regarding their preadolescent child's presence during discussions about serious illnesses. METHODS: In-depth qualitative interviews with parents of children receiving treatment for acute lymphoblastic leukemia were conducted. Parents were sampled from 6 UK treatment centers. Analysis was informed by the constant comparative method and content analysis. RESULTS: We report on interviews with 53 parents (33 mothers, 20 fathers). Parents acknowledged the benefits of communicating openly with children, but few thought that their child's presence in discussions was straightforwardly desirable. They described how their child's presence restricted their own communication with physicians, made concentrating difficult, and interfered with their efforts to care for their child emotionally. Children's presence was particularly difficult when significant issues were being discussed, including prognoses, adverse results, and certain medical procedures. Parents felt that such discussions posed a potential threat to their child, particularly when they had not first had an opportunity to discuss information with the physician separately from the child. In contrast, separate meetings enabled parents to absorb information and to convey it to their child at an appropriate time and in a reassuring way. Some parents experienced difficulties in accessing separate meetings with physicians. CONCLUSIONS: The difficulties parents described could potentially be addressed by extending, beyond the diagnosis period, the practice of sequencing significant information so that it is communicated to parents in separate meetings before being communicated to the child and by periodically exploring with parents what information would be in each child's interests.

Parents' verbal communication and childhood anxiety: a systematic review

Parents’ verbal communication to their child, particularly the expression of fear-relevant information (e.g., attributions of threat to the environment), is considered to play a key role in children’s fears and anxiety. This review considers the extent to which parental verbal communication is associated with child anxiety by examining research that has employed objective observational methods. Using a systematic search strategy, we identified 15 studies that addressed this question. These studies provided some evidence that particular fear-relevant features of parental verbal communication are associated with child anxiety under certain conditions. However, the scope for drawing reliable, general conclusions was limited by extensive methodological variation between studies, particularly in terms of the features of parental verbal communication examined and the context in which communication took place, how child anxiety was measured, and inconsistent consideration of factors that may moderate the verbal communication–child anxiety relationship. We discuss ways in which future research can contribute to this developing evidence base and reduce further methodological inconsistency so as to inform interventions for children with anxiety problems.

Study on the application of cool paintings for the passive cooling of existing buildings in Mediterranean climates

Building roofs play a very important role in the energy balance of buildings, especially in summer, when they are hit by a rather high solar irradiance. Depending on the type of finishing layer, roofs can absorb a great amount of heat and reach quite high temperatures on their outermost surface, which determines significant room overheating. However, the use of highly reflective cool materials can help to maintain low outer surface temperatures; this practice may improve indoor thermal comfort and reduce the cooling energy need during the hot season.This technology is currently well known and widely used in the USA, while receiving increasing attention in Europe. In order to investigate the effectiveness of cool roofs as a passive strategy for passive cooling in moderately hot climates, this paper presents the numerical results of a case study based on the dynamic thermal analysis of an existing office building in Catania (southern Italy, Mediterranean area). The results show how the application of a cool paint on the roof can enhance the thermal comfort of the occupants by reducing the operative temperatures of the rooms and to reduce the overall energy needs of the building for space heating and cooling.

Neuronal Expression of Cd36, Cd44, and Cd83 Antigen Transcripts Maps to Distinct and Specific Murine Brain Circuits

Cells recruited by the innate immune response rely on surface-expressed molecules in order to receive signals from the local environment and to perform phagocytosis, cell adhesion, and others processes linked to host defense. Hundreds of surface antigens designated through a cluster of differentiation (CD) number have been used to identify particular populations of leukocytes. Surprisingly, we verified that the genes that encode Cd36 and Cd83 are constitutively expressed in specific neuronal cells. For instance, Cd36 mRNA is expressed in some regions related to circuitry involved in pheromone responses and reproductive behavior. Cd44 expression, reanalyzed and detailed here, is associated with the laminar formation and midline thalamic nuclei in addition to striatum, extended amygdala, and a few hypothalamic, cortical, and hippocampal regions. A systemic immune challenge was able to increase Cd44 expression quickly in the area postrema and motor nucleus of the vagus but not in regions presenting expressive constitutive expression. In contrast to Cd36 and Cd44, Cd83 message was widely distributed from the olfactory bulb to the brain stem reticular formation, sparing the striatopallidum, olivary region, and cerebellum. Its pattern of expression nevertheless remained strongly associated with hypothalamic, thalamic, and hindbrain nuclei. Unlike the other transcripts, Cd83 mRNA was rapidly modulated by restraint stress. Our results indicate that these molecules might play a role in specific neural circuits and present functions other than those attributed to leukocyte biology. The data also suggest that these surface proteins, or their associated mRNA, could be used to label neurons in specific circuits/regions. J. Comp. Neurol. 517:906-924, 2009.

Addressing the potential adverse effects of school-based BMI assessments on children

Introduction. Do child obesity prevention research and intervention measures have the potential to generate adverse concerns about body image by focussing on food, physical activity and body weight? Research findings now demonstrate the emergence of body image concerns in children as young as 5 years. In the context of a large school-community-based child health promotion and obesity prevention study, we aimed to address the potential negative effects of height and weight measures on child wellbeing by developing and implementing an evidence-informed protocol to protect and prevent body image concerns. fun 'n healthy in Moreland! is a cluster randomised controlled trial of a child health promotion and obesity prevention intervention in 23 primary schools in an inner urban area of Melbourne, Australia. Body image considerations were incorporated into the study philosophies, aims, methods, staff training, language, data collection and reporting procedures of this study. This was informed by the published literature, professional body image expertise, pilot testing and implementation in the conduct of baseline data collection and the intervention. This study is the first record of a body image protection protocol being an integral part of the research processes of a child obesity prevention study. Whilst we are yet to measure its impact and outcome, we have developed and tested a protocol based on the evidence and with support from stakeholders in order to minimise the adverse impact of study processes on child body image concerns.

Parent-reported health status of overweight and obese Australian primary school children: a cross-sectional population survey

Introduction: Childhood overweight/obesity is associated with poor physical and psychosocial health in clinical samples. However, there is little information on the health status of overweight and obese children in the community, who now represent a large proportion of the child population. We examined parent-reported child health and well-being and parent concern about child weight by body mass index (BMI) category in a population sample of primary school children.

Design: A stratified two-stage random cluster sample of 24 primary schools representative of the state of Victoria, Australia.

Measures: BMI (weight/height2) transformed to normalised Z-scores using the 1990 UK Growth Reference; the Child Health Questionnaire (CHQ), a 13-scale 50-item parent-completed measure of health and well-being; parent self-reported height and weight; parent concern about child's weight.

Results: Data were available for 2863 children aged 5-13 y (50.5% male), of whom 17% were overweight and 5.7% obese. Using logistic regression analyses with 'normal weight' as the referent category, obese boys were at greater risk of poor health (ie <15th centile) on seven of the 12 CHQ scales: Physical Functioning (odds ratio (OR) 2.8), Bodily Pain (OR 1.8), General Health (OR 3.5), Mental Health (OR 2.8), Self Esteem (OR 1.8), Parent Impact¾Emotional (OR 1.7) and Parent Impact¾Time (OR 1.9). Obese girls were at greater risk of poor health on only two scales: General Health (OR 2.1) and Self Esteem (OR 1.8). Forty-two percent of parents with obese children and 81% with overweight children did not report concern about their child's weight. Parents were more likely to report concern if the child was obese (OR 21.3), overweight (OR 3.5) or underweight (OR 5.4) than normal weight (P<0.05). Concern was not related to child gender, parental BMI or parental education after controlling for child BMI. Perceived health and well-being of overweight/obese children varied little by weight category of the reporting parent (overweight vs non-overweight).

Conclusions: Parents were more likely to report poorer health and well-being for overweight and obese children (particularly obese boys). Parental concern about their child's weight was strongly associated with their child's actual BMI. Despite this, most parents of overweight and obese children did not report poor health or well-being, and a high proportion did not report concern. This has implications for the early identification of such children and the success of prevention and intervention efforts.
