Development of a screening tool enabling identification of infants and toddlers at risk for family abuse and neglect : A feasibility study from three South European countries

Background: Child abuse is a health and social problem, and few screening instruments are available for the detection of risk in primary health care. The aim was to develop a screening instrument to be used by professionals in the public health care sector, thus enabling the detection of infants and toddlers at risk of emotional and physical abuse and neglect, and to provide evidence for the feasibility of the instrument in Cyprus, Greece and Spain. Method: A total of 50 health professionals from paediatric public health-care centres in the three countries were involved in a three-step process for guiding the development of the screening tool and its application. Results: A nine-item screening tool, consisting of items assessing relational emotional abuse, physical abuse and other risk factors, was developed. The screening tool was applied on a total of 219 families with 0 to 3-year-old children attending public health centres in the three countries. Clinicians reported that they agreed on the inclusion of the questions (86.4-100%) and that they found the questions to be useful for the clinical evaluation of the family (63.2-100%). Conclusion: The screening tool shows considerable face validity and was reported feasible by an international set of clinician

The mode of lymphoblastoid cell death in response to gas phase cigarette smoke is dose-dependent

<p>Abstract</p> <p>Background</p> <p>Cigarette smoke (CS) is the main cause in the development of chronic obstructive pulmonary disease (COPD), the pathogenesis of which is related to an extended inflammatory response. In this study, we investigated the effect of low and high doses of gas phase cigarette smoke (GPS) on cultured lymphocyte progenitor cells, using techniques to assess cell viability and to elucidate whether cells die of apoptosis or necrosis upon exposure to different doses of GPS.</p> <p>Methods</p> <p>In our approach we utilised a newly-established system of exposure of cells to GPS that is highly controlled, accurately reproducible and simulates CS dosage and kinetics that take place in the smokers' lung. This system was used to study the mode of cell death upon exposure to GPS in conjunction with a range of techniques widely used for cell death studies such as Annexin V staining, activation of caspase -3, cytoplasmic release of cytochrome C, loss of mitochondrial membrane potential and DNA fragmentation.</p> <p>Results</p> <p>Low doses of GPS induced specific apoptotic indexes in CCRF-CEM cells. Specifically, cytochrome C release and cleaved caspase-3 were detected by immunofluorescence, upon treatment with 1-3 puffs GPS. At 4 h post-exposure, caspase-3 activation was observed in western blot analysis, showing a decreasing pattern as GPS doses increased. Concomitant with this behaviour, a dose-dependent change in Δψ_mdepolarization was monitored by flow cytometry 2 h post-exposure, while at 4 h Δψ_mcollapse was observed at the higher doses, indicative of a shift to a necrotic demise. A reduction in DNA fragmentation events produced by 5 puffs GPS as compared to those provoked by 3 puffs GPS, also pointed towards a necrotic response at the higher dose of GPS.</p> <p>Conclusion</p> <p>Collectively, our results support that at low doses gas phase cigarette smoke induces apoptosis in cultured T-lymphocytes, whereas at high doses GPS leads to necrotic death, by-passing the characteristic stage of caspase-3 activation and, thus, the apoptotic route.</p

Expressão da capacidade de empatia em bebês de 8 e 18 semanas

Este estudo investigou o padrão temporal e expressivo da capacidade de empatia em bebês de 8 e 18 semanas no contexto de interações face-face entre 90 duplas de mãe-bebê. As interações foram analisadas em tempo real e através de micro-análise. Alguns comportamentos infantis apresentaram maior probabilidade de fazerem parte do padrão expressivo da empatia do que outros. Ainda, o padrão expressivo se manifestou diferente em instâncias de empatia com emoções negativas e instâncias de empatia com emoções positivas comunicadas pela mãe. Em relação ao padrão temporal, observou-se que a manifestação da capacidade de empatia ocorreu dentro de um intervalo de tempo igual de ½ segundo antes e 1 segundo depois da mudança emocional da mãe. Os resultados indicam a necessidade de reavaliação das proposições tradicionais sobre as capacidades comunicativas precoces de bebês, e sugerem uma coerência entre os achados e as proposições teóricas contemporâneas na área da Psicologia Infantil

Depth zonation in a Parapandalus narval (Crustacea, Decapoda, Pandalidae) population from Rhodos Island, Greece

The population characteristics of Parapandalus narval are related to depth. Sex ratio (females/males and females) decreases with depth, while female size increases. Dry weight of equal sized individuals decreases with depth. For the 23 and 80 + 140 m females, the relative dry weight reduction was estimated to 10·3% and 16·0% compared to that of the 5 m females, respectively. Males (80-220 m) exhibited the greatest reduction of 19·9%. It is suggested that the depth zonation exhibited by the P. narval population is related to habitat differences along the depth range sampled and has to do with the exploitation of the available food resources by different sex and/or size groups. © 1989

Mediterranean Fever Gene Mutations in Greek Patients with Behcet’s Disease

Objective: It is known that clinical similarities between Behcet’s disease and Familial Mediterranean Fever have led to the hypothesis of a common pathogenesis. Familial Mediterranean Fever is caused by MEFV gene mutations coding for pyrin. Therefore, we examined whether these pyrin mutations are also associated with Behcet’s disease. Methods: Molecular testing for pyrin mutations was performed in 96 unrelated Greek patients with an established diagnosis of Behcet’s disease. The results were compared with an analysis for pyrin mutations in 140 unrelated healthy Greek controls. Results: We found no pyrin mutations among the Behcet cases tested; this result is comparable with the control group. Conclusions: Pyrin gene mutations in Greek patients with Behcet’s disease are not more common than those in the general population. This finding is not in agreement with the findings in other populations. It is suggested that screening for pyrin mutations not be included in the evaluation of Greeks suspected to have Behcet’s disease. Keywords: Behcet’s disease, familial mediterranean fever, Greece, pyrin "Mutaciones en el Gen de la Fiebre Mediterránea en Pacientes Griegos con la Enfermedad de Behçet" RESUMEN Objetivo: Se sabe que las similitudes clínicas entre la enfermedad de Behçet y la fiebre mediterránea familiar han llevado a la hipótesis de una patogénesis común. La fiebre mediterránea familiar es causada por mutaciones en el gen MEFV que codifica la pirina. Por lo tanto, examinamos si estas mutaciones de la pirina se hallan también asociadas con la enfermedad de Behçet. Métodos: La prueba molecular para la detección de las mutaciones de la pirina se realizó en 96 pacientes griegos no relacionados, y diagnosticados con la enfermedad de Behçet. Los resultados se compararon con un análisis de las mutaciones de la pirina en 140 controles formados por individuos griegos saludables. Resultados: No se encontraron mutaciones de pirina entre los casos de Behçet sometidos a prueba. Este resultado es comparable con el grupo control. Conclusiones: Las mutaciones del gen de la pirina en los pacientes griegos con la enfermedad de Behçet no son más comunes que las de la población general. Este hallazgo no concuerda con los hallazgos en otras poblaciones. Se sugiere que el tamizaje para la detección de las mutaciones de pirina no se incluya en la evaluación de pacientes griegos sospechosos de padecer la enfermedad de Behçet.
