Risk normalization in sunlight exposure
The present study focuses on the understanding of whether there is a process of risk
normalization, due to the use of positive illusions, in individuals who expose themselves to
sunlight on the beach. A pilot study (N = 44) evidenced that the positive illusions most referred
are the use of protective measures during exposition at unrecommended time. To understand
whether knowledge of sunlight exposure risks and risk perception could be negatively
associated, due to the use of protective measures, a questionnaire was applied to a convenience
sample (N = 276). The sample was reduced in two groups that reported being exposed between
12 am and 3 pm - low protective behaviors (n = 74) and high (n = 41). Results illustrate the
normalization process only in individuals who have high protection behaviors, as expected. The
effect of moderating variables was also tested: mediation of the consequences of risk in time
and health literacy in the relation between knowledge of risks and risk perception. Only health
literacy had a significant effect, decreasing normalization. The role of knowledge of benefits
was also explored. It was positively related to risk perception and this relation was moderated
by mediation in time.
This study suggests that it is important to a) warn that the use of protective measures
during the hazardous time does not guarantee immunity, b) promote health literacy, as it can
minimize risk normalization c) understand how information on risks and benefits interact to
influence risk perception.O presente estudo tem como objetivo explorar a existência de um processo de
normalização de risco, devido à utilização de ilusões positivas, nos indivíduos que se expõem
ao sol na praia. Com base num estudo piloto (N = 44) aferiu-se que as ilusões positivas mais
referidas pelos indivíduos são a utilização de medidas de proteção complementares, como o
protetor solar ou a ingestão de água, ao invés da não exposição ao sol durante o horário
considerado mais perigoso (12h-15h). Para compreender se a utilização destas medidas de
proteção se poderia associar a um processo de normalização de risco à exposição solar, aplicouse um questionário (N = 276) a uma amostra de conveniência, que foi reduzida em dois grupos
tendo por base a média dos comportamentos de proteção – baixos comportamentos de proteção
(n = 74) e altos comportamentos de proteção (n = 41). Os resultados indicam que existem
diferenças entre as amostras relativamente ao processo de normalização de risco. Como
esperado, para os indivíduos que têm elevados comportamentos de proteção e se expõem ao sol
no horário mais perigoso existe uma relação negativa entre o conhecimento de risco e a
perceção de risco da exposição solar (i.e., existe normalização de risco) mas não nos indivíduos
que se expõem fora desse horário. Foi também testado o efeito de variáveis moderadoras:
mediação das consequências do risco no tempo e literacia em saúde na relação entre
conhecimento e perceção de risco. Apenas a literacia em saúde teve um efeito significativo,
tendo contrariado o efeito de normalização. Sendo que nos últimos anos se tem enfatizado
também os benefícios da exposição solar, explorou-se ainda qual seria a relação entre o
conhecimento de benefícios e a perceção de risco e qual o papel das variáveis moderadoras.
Verificou-se a existência de uma relação positiva entre conhecimento de benefícios e perceção
de risco de exposição solar, sendo esta relação moderada pela mediação das consequências do
risco no tempo. Quando os indivíduos consideram que as consequências do risco são tardias, o
conhecimento de benefícios associa-se a uma menor perceção de risco.
Este estudo tem implicações que poderão ser relevantes para a comunicação do risco.
Em particular importa: a) alertar que a utilização de medidas de proteção durante o horário
mais perigoso não garante imunidade ao risco da exposição solar; b) apostar na promoção em
literacia em saúde para minimizar a normalização de riscos; c) compreender como os riscos e
os benefícios associados à exposição solar interagem para influenciar a perceção de risc
Perceções e conhecimentos sobre o acolhimento familiar no contexto Português: Um estudo com uma amostra da comunidade
O acolhimento familiar é uma medida de promoção e proteção para crianças e jovens em perigo considerada preferencial pela sua colocação num contexto familiar, que lhes proporciona um melhor nível de desenvolvimento e bem-estar. Porém, em Portugal verifica-se uma predominância significativa da medida de acolhimento residencial, sendo que apenas um número reduzido de crianças e jovens se encontra integrado em acolhimento familiar (i.e., cerca de 3%), sendo o número de famílias de acolhimento insuficiente face às necessidades do sistema.
Neste sentido, o objetivo deste estudo passa por explorar os conhecimentos e as perceções acerca da medida de acolhimento familiar e das famílias de acolhimento de uma amostra da comunidade portuguesa (n=404, 55% do sexo feminino, com idades compreendidas entre os 26 e os 72 anos), assim como, por explorar os preditores da intenção em se tornar família de acolhimento. Os resultados demonstraram conhecimentos significativos acerca do acolhimento familiar, assim como, perceções, maioritariamente, positivas acerca da referida medida e das famílias de acolhimento, ainda que se tenham verificado algumas dúvidas e opiniões ambíguas. Adicionalmente, os resultados indicaram que as perceções positivas acerca das famílias de acolhimento (p=.002), estar numa relação de intimidade (p=.082) e ser do sexo feminino (p=.052) estão positivamente associadas à intenção em se tornar família de acolhimento. Os resultados serão discutidos à luz da literatura neste domínio, sendo também identificadas implicações para a prática profissional. Uma maior disseminação e contacto com as famílias de acolhimento é fundamental com vista ao recrutamento e seleção de novas famílias de acolhimento.Foster care is a preferable alternative care context for abused and neglected children, which enhances their development and well-being. However, in Portugal there is a significant predominance of residential care, and only a small number of children and teenagers is placed in foster care (i.e., around 3%). Also, the number of foster families is lacking to cover the needs.
Therefore, the aim of this study is to explore public knowledge and perceptions of foster care and foster families through a Portuguese community sample (n=404, 55% female, aged between 26 and 72 years old), as well as, to identify the predictors of the intention to become a foster family. In general, the results showed that participants have significant knowledge about foster care and mostly positive perceptions about foster care and families, although there were some doubts and ambiguous opinions. Additionally, the results showed that positive perceptions about foster families (p=.002), having an intimate relationship (p=.082) and being female (p=.052) are positively associated with greater intention to become a foster family. The results will be discussed in the light of the literature, and implications for professional practice will also be identified. Greater dissemination and contact with foster families are essential to recruit and select new foster families
Risk perception normalization of sunlight exposure
Health organizations recommend avoiding direct sunlight exposure usually between 11 am and 5 pm. Nevertheless, it is common to see people on the beach during all day. This study focuses on understanding if sunlight exposure risk might be normalized. Risk normalization is a process by which people minimize a perceive threat to psychologically cope with it, frequently by using positive illusions. A pilot study (N = 44) suggests that the positive illusions most referred to explain exposition at unrecommended hours are the use of protective measures. To explore if knowledge of sunlight exposure risk and risk perception were negatively associated, illustrating risk normalization, a questionnaire was applied to a convenience sample (N = 276). This effect was found among those individuals that exposed themselves to sunlight between 12 am and 3 pm and reported a use of protective measures that was above the average. Furthermore, health literacy moderated the negative relation between knowledge and risk perception. This study suggests that it is important communicating that the use of protective measures during unrecommended hours does not guarantee protection, promoting health literacy, as it can minimize risk normalization, and understanding how information on risks and benefits interacts to influence risk perception
Exploiting the antiparasitic activity of naphthalimides derivatives
A set of 1,8-naphtalimides derivatives were synthesized and tested against three protozoans that cause important human diseases: Leishmaniainfantum, Trypanosomabrucei and Trypanosomacruzi. Additionally, toxicity was determined by growth inhibition of THP-1 derived macrophages. The results suggest that chemical modifications in the carbon chain linking the naphthalimide and the substituting groups have different effects in the parasites. This work should provide new insights new insights for the design and optimization of more potent and directed naphthalimide derivatives against these organisms.The research leading to these results has received funding from the European Community’s Seventh Framework Programme under grant agreements No.602773 (Project KINDRED).

Presupuestos sensibles al género en el marco de la cooperación UE-AL. Un estudio internacional comparado
Los presupuestos sensibles al género han sido impulsados en diversos países con el fin de reducir brechas de género al distribuir y orientar de manera más adecuada y equitativa los fondos públicos. Si bien las primeras experiencias datan de la década del 80, la Declaración y Plataforma para la Acción de Beijing adoptadas en septiembre de 1995 en el marco de Naciones Unidas, representó un punto de inflexión para el avance de este tipo de medidas dado que se instó explícitamente a los Estados a adoptar la perspectiva de género en el ámbito presupuestario.
El presente trabajo pretende realizar una contribución al estudio de los presupuestos sensibles al género, en particular analizando las experiencias de Argentina, Brasil, Estado de Guanajuato y COSEFIN, y la contribución del programa Eurosocial, financiado por la Unión Europea. De esta manera, se busca conocer cómo se ha desarrollado el proceso de implementación de tales presupuestos en el contexto referido. El valor de esta investigación radica en que se pone el foco de atención en dicho proceso, a partir del análisis de la información documental existente en los archivos de las instituciones estudiadas y de la recogida de datos primarios a través del desarrollo de entrevistas a las personas expertas que han tenido un importante rol en las iniciativas.Universidad de Málaga.

Comparative context analysis of codon pairs on an ORFeome scale
Codon context is an important feature of gene primary structure that modulates mRNA decoding accuracy. We have developed an analytical software package and a graphical interface for comparative codon context analysis of all the open reading frames in a genome (the ORFeome). Using the complete ORFeome sequences of Saccharomyces cerevisiae, Schizosaccharomyces pombe, Candida albicans and Escherichia coli, we show that this methodology permits large-scale codon context comparisons and provides new insight on the rules that govern the evolution of codon-pair context

Upper gastrointestinal bleeding during the COVID-19 pandemic; particularities of diagnosis and therapy
SARS-COV 2 recently caused a global pandemic, with the first case being reported in Romania in February 2020. Important restrictive measures were imposed, so that the addressability of patients to medical services decreased. Upper gastrointestinal bleeding had more severe forms of evolution at the time of presentation, which required additional methods of diagnosis and treatment. This is a retrospective study performed on 268 patients, which aims to evaluate the type and effectiveness of different treatment methods for upper gastrointestinal bleeding during the COVID 19 pandemic. Severity assessment was performed by measuring the Rockall score and additional methods of diagnosis. The association of COVID-19 with upper gastrointestinal bleeding can lead to much more severe outcomes for the patient, so treatment must be sustained and fast established. If the initial therapeutic methods fail, the other available therapeutic measures should be introduced progressively and without delay to achieve the best possible outcomes

In these situations, differentiating between prematurity and small for gestational age (SGA) or simultaneous conditions is essential to ensuring adequate care. Such diagnoses, however, depend on reliable pregnancy dating, which can be challenging in developing countries. A new medical optoelectronic device was developed to estimate gestational age (GA) at birth based on newborn skin reflection.
Objective: This study will aim to evaluate the device's ability to detect prematurity or SGA, or both conditions simultaneously as well as predict short-term pulmonary complications in a cohort of low-birth-weight newborns.
Methods: This study protocol was designed for a multicenter cohort including referral hospitals in Brazil and Mozambique. Newborns weighing 500-2500 g will be eligible for inclusion with the best GA available, considering the limited resources of low-income countries. Comparator-GA is based on reliable last menstrual period dating or ultrasound assessment before 24 weeks' gestation. Estimated GA at birth (Test-GA) will be calculated by applying a novel optoelectronic device to the newborn's skin over the sole. The average difference between Test-GA and Comparator-GA will be analyzed, as will the percentage of newborns who are correctly diagnosed as preterm or SGA. In addition, in a nested case-control study, the accuracy of skin reflection in the prediction of prematurity-related respiratory problems will be evaluated. The estimated required sample size is 298 newborns.
Results: Teams of health professionals were trained, and standard operating procedures were developed following the good practice guidelines for the clinical investigation of medical devices for human participants. The first recruitment started in March 2019 in Brazil. Data collection is planned to end in December 2020, and the results should be available in March 2021.
Conclusions: The results of this clinical study have the potential to validate a new device to easily assess postnatal GA, supporting SGA identification when pregnancy dating is unreliable or unknown.This research was supported by a Grand Challenges Exploration grant from the Bill & Melinda Gates Foundation (Grant No. OPP1128907, Contract; http://www.gatesfoundation.org/) and the Fundação de Amparo a Pesquisa de Minas Gerais, Brazil (Grant Nos AUC-00032-15 and PPM 0247/16; http://www.fapemig.br/en/; nonprofit sector).
