The lip:A histologic and analytical approach of relevance to esthetic plastic surgery

This is a study done for the first time to understand the histologic features of the lip deeply, quantitatively, and analytically and identify the differences between the outer, intermediate, and inner parts of the lips. Previous researchers did not tackle the histologic features of the lip from this point of view. Half lip was obtained from different well-preserved cadavers where the upper lip, lower lip, and lip angle were evaluated by coronal histologic sections. A total of 43 slides were studied and photographed using light and digital microscopes (Nikon COOLSCOPE, Nikon Corporation, Tokyo, Japan), respectively. The cadavers (26 men and 17 women) were in the age group of 45 to 65 years old, and older than 65 years. Data were entered on a study pro forma and statistically analyzed. Normal histologic features of the upper lip, intermediate, and the inner lip sections were observed. Fibrous septations that sometimes had muscular components inserting into them could be identified. In between these septations, there were loose areas (chambers). The mean numbers of chambers identified in the upper and lower lips were higher in the red areas, and more septations and chambers were identified in the lower lip. New histologic observations were classified into types 1 to 7. Significant relations were identified between the total number of septations and chambers in relation to age group and sex. Higher means of septations and chambers were detected in the age group older than 65 years, and in women as a whole. In conclusion, the findings detected in this work could explain the congenital lip pits that are familial or syndromic and many post-lip augmentation complications. © 2009 Lippincott Williams & Wilkins, Inc.

S100A2 is a BRCA1/p63 coregulated tumour suppressor gene with roles in the regulation of mutant p53 stability

Here, we show for the first time that the familial breast/ovarian cancer susceptibility gene, BRCA1, along with interacting ΔNp63 proteins, transcriptionally upregulate the putative tumour suppressor protein, S100A2. Both BRCA1 and ΔNp63 proteins are required for S100A2 expression. BRCA1 requires ΔNp63 proteins for recruitment to the S100A2 proximal promoter region, while exogenous expression of individual ΔNp63 proteins cannot activate S100A2 transcription in the absence of a functional BRCA1. Consequently, mutation of the ΔNp63/p53 response element within the S100A2 promoter completely abrogates the ability of BRCA1 to upregulate S100A2. S100A2 shows growth control features in a range of cell models. Transient or stable exogenous S100A2 expression inhibits the growth of BRCA1 mutant and basal-like breast cancer cell lines, while short interfering RNA (siRNA) knockdown of S100A2 in non-tumorigenic cells results in enhanced proliferation. S100A2 modulates binding of mutant p53 to HSP90, which is required for efficient folding of mutant p53 proteins, by competing for binding to HSP70/HSP90 organising protein (HOP). HOP is a cochaperone that is required for the efficient transfer of proteins from HSP70 to HSP90. Loss of S100A2 leads to an HSP90-dependent stabilisation of mutant p53 with a concomitant loss of p63. Accordingly, S100A2-deficient cells are more sensitive to the HSP-90 inhibitor, 17-N-allylamino-17-demethoxygeldanamycin, potentially representing a novel therapeutic strategy for S100A2- and BRCA1-deficient cancers. Taken together, these data demonstrate the importance of S100A2 downstream of the BRCA1/ΔNp63 signalling axis in modulating transcriptional responses and enforcing growth control mechanisms through destabilisation of mutant p53.

Next-generation sequencing-based molecular diagnosis of 82 retinitis pigmentosa probands from Northern Ireland

Retinitis pigmentosa (RP) is a group of inherited retinal disorders characterized by progressive photoreceptor degeneration. An accurate molecular diagnosis is essential for disease characterization and clinical prognoses. A retinal capture panel that enriches 186 known retinal disease genes, including 55 known RP genes, was developed. Targeted next-generation sequencing was performed for a cohort of 82 unrelated RP cases from Northern Ireland, including 46 simplex cases and 36 familial cases. Disease-causing mutations were identified in 49 probands, including 28 simplex cases and 21 familial cases, achieving a solving rate of 60 %. In total, 65 pathogenic mutations were found, and 29 of these were novel. Interestingly, the molecular information of 12 probands was neither consistent with their initial inheritance pattern nor clinical diagnosis. Further clinical reassessment resulted in a refinement of the clinical diagnosis in 11 patients. This is the first study to apply next-generation sequencing-based, comprehensive molecular diagnoses to a large number of RP probands from Northern Ireland. Our study shows that molecular information can aid clinical diagnosis, potentially changing treatment options, current family counseling and management.

Factors influencing success of clinical genome sequencing across a broad spectrum of disorders

To assess factors influencing the success of whole-genome sequencing for mainstream clinical diagnosis, we sequenced 217 individuals from 156 independent cases or families across a broad spectrum of disorders in whom previous screening had identified no pathogenic variants. We quantified the number of candidate variants identified using different strategies for variant calling, filtering, annotation and prioritization. We found that jointly calling variants across samples, filtering against both local and external databases, deploying multiple annotation tools and using familial transmission above biological plausibility contributed to accuracy. Overall, we identified disease-causing variants in 21% of cases, with the proportion increasing to 34% (23/68) for mendelian disorders and 57% (8/14) in family trios. We also discovered 32 potentially clinically actionable variants in 18 genes unrelated to the referral disorder, although only 4 were ultimately considered reportable. Our results demonstrate the value of genome sequencing for routine clinical diagnosis but also highlight many outstanding challenges.

An original phylogenetic approach identified mitochondrial haplogroup T1a1 as inversely associated with breast cancer risk in BRCA2 mutation carriers

Introduction: Individuals carrying pathogenic mutations in the BRCA1 and BRCA2 genes have a high lifetime risk of breast cancer. BRCA1 and BRCA2 are involved in DNA double-strand break repair, DNA alterations that can be caused by exposure to reactive oxygen species, a main source of which are mitochondria. Mitochondrial genome variations affect electron transport chain efficiency and reactive oxygen species production. Individuals with different mitochondrial haplogroups differ in their metabolism and sensitivity to oxidative stress. Variability in mitochondrial genetic background can alter reactive oxygen species production, leading to cancer risk. In the present study, we tested the hypothesis that mitochondrial haplogroups modify breast cancer risk in BRCA1/2 mutation carriers.

Methods: We genotyped 22,214 (11,421 affected, 10,793 unaffected) mutation carriers belonging to the Consortium of Investigators of Modifiers of BRCA1/2 for 129 mitochondrial polymorphisms using the iCOGS array. Haplogroup inference and association detection were performed using a phylogenetic approach. ALTree was applied to explore the reference mitochondrial evolutionary tree and detect subclades enriched in affected or unaffected individuals.

Results: We discovered that subclade T1a1 was depleted in affected BRCA2 mutation carriers compared with the rest of clade T (hazard ratio (HR) = 0.55; 95% confidence interval (CI), 0.34 to 0.88; P = 0.01). Compared with the most frequent haplogroup in the general population (that is, H and T clades), the T1a1 haplogroup has a HR of 0.62 (95% CI, 0.40 to 0.95; P = 0.03). We also identified three potential susceptibility loci, including G13708A/rs28359178, which has demonstrated an inverse association with familial breast cancer risk.

Conclusions: This study illustrates how original approaches such as the phylogeny-based method we used can empower classical molecular epidemiological studies aimed at identifying association or risk modification effects.

Infrequent mutations of Archipelago (hAGO, hCDC4, Fbw7) in primary ovarian cancer

Objective: Archipelago (AGO, also known as hCdc4, Fbw7, or Sel-10) is an F-box containing component of the SCF complex implicated in the ubiquitination and proteolysis of cyclin E and c-Myc, and found to be mutated in 16% of endometrial carcinomas. We have previously reported somatic mutations in AGO in 3/10 ovarian cancer cell lines, but the frequency of such mutations in primary ovarian cancer is unknown.

Methods: The coding sequence of AGO was analyzed in 95 primary sporadic ovarian tumors and 16 cases of familial ovarian cancer, and correlated with levels of cyclin E and c-Myc protein expression. Constructs encoding mutations in AGO were transfected into an AGO-null cell line to directly test their ability to regulate cyclin E and c-Myc levels.

Results: Mutations were present in only 2 of 95 sporadic cases: a premature stop within the WD domain (471 Ter) and a missense change near the F-box (S245T). Both primary tumor specimens containing these mutations showed high levels of cyclin E and c-Myc, but reconstitution of an AGO-null cell line with constructs encoding these mutations showed 471 Ter to be inactive in regulating endogenous cyclin E and c-Myc levels, while the S245T mutant was indistinguishable from wild-type. No germ-line mutations were found in familial cases of ovarian cancer.

Conclusion: Somatic AGO mutations are infrequent in primary ovarian cancers and are unlikely to contribute to familial ovarian cancer. Reconstitution experiments, rather than measuring tumor levels of cyclin E and c-Myc, provide an effective approach to determine the functional significance of AGO mutations identified in human cancers.

Brca1 and brca2:Role in the DNA damage response, cancer formation and treatment

BRCA1 and BRCA2 are highly penetrant breast and ovarian cancer susceptibility genes that are mutated in a significant proportion of familial breast and ovarian cancer syndromes. Both of these genes are tumour suppressors, the products of which play vital roles in the cellular response to DNA damage. These proteins function in a number of cellular pathways in order to maintain genomic stability including DNA damage signaling, DNA repair, cell cycle regulation, protein ubiquitination, chromatin remodeling, transcriptional regulation and apoptosis. This chapter will discuss the functions of these proteins and how they relate to tumour development, and therapy. © 2009 Springer Science+Business Media B.V.

Parker Morris and the Fordist House

6.00 pm. If people like watching T.V. while they are eating their evening meal, space for a low table is needed (Ministry of Housing and Local Government, Space in the Home, 1963, p. 4).

This paper re-examines the 1961 Parker Morris report on housing standards in Britain. It explores the origins, scope, text and iconography of the report and suggests that these not only express a particularly modernist conception of space but one which presupposed very specific economic conditions and geographies.

Also known as Homes for Today and Tomorrow Parker Morris attempted, through the application of scientific principles, to define the minimum living space standards needed to accommodate household activities. But while early modernist research into notions of existenzminimum were the work of avant-garde architects and thinkers, Homes for Today and Tomorrow and its sister design manual Space in the Home were commissioned by the British State. This normalization of scientific enquiry into space can be considered not only as a response to new conditions in the mass production of housing – economies of scale, prefabrication, system-building and modular coordination – but also to the post-war boom in consumer goods. In this, it is suggested that the domestic interior was assigned a key role as a privileged site of mass consumption as the production and micro-management of space in Britain became integral to the development of a planned national economy underpinned by Fordist principles. Parker Morris, therefore, sought to accommodate activities which were pre-determined not so much by traditional social or familial ties but rather by recently introduced commodities such as the television set, white goods, table tennis tables and train sets. This relationship between the domestic interior and the national economy are emblematized by the series of placeless and scale-less diagrams executed by Gordon Cullen in Space in the Home. Here, walls dissolve as space flows from inside to outside in a homogenized and ephemeral landscape whose limits are perhaps only the boundaries of the nation state and the circuits of capital.

In Britain, Parker Morris was the last explicit State-sponsored attempt to prescribe a normative spatial programme for national living. The calm neutral efficiency of family-life expressed in its diagrams was almost immediately problematised by the rise of 1960s counter-culture, the feminist movement and the oil crisis of 1972 which altered perhaps forever the spatial, temporal and economic conditions it had taken for granted. The debate on space-standards, however, continues.

Population density and refractive error among Chinese children.

PURPOSE: China is urbanizing rapidly, and the prevalence of myopia is high. This study was conducted to identify the reasons for observed differences in the prevalence of myopia among urban versus rural Chinese children. METHODS: All children with uncorrected acuity of 6/12 or worse and a 50% random sample of children with vision better than 6/12 at all secondary schools in mixed rural-urban Liangying Township, Guangdong, underwent cycloplegic refraction, and provided data on age, gender, parental education, weekly near work and time outdoors, and urban development level of respondents' neighborhoods (12-item questionnaire). Population density of 32 villages and urban zones in Liangying was calculated from census figures (mean population density, 217 persons/km(2); range, 94-957; mean for Guangdong, 486). RESULTS: Among 5844 eligible children, 4612 (78.9%) had parental consent and completed examinations; 2957 were refracted per protocol, and 2480 (83.9%) of these had questionnaire data. Those with completed examinations were more likely to be girls (P < 0.001), and questionnaire respondents were more myopic (P = 0.02), but otherwise did not differ significantly from nonrespondents. In multivariate models, older age (P < 0.001), more near work (P = 0.02), and higher population density (P = 0.003), but not development index, parental education, or time outdoors were significantly associated with more myopic refractive error. CONCLUSIONS: Higher population density appears to be associated with myopia risk, independent of academic activity, time spent outdoors, familial educational level, or economic development, factors that have been thought to explain higher myopia prevalence among urban children. Mechanisms for this apparent association should be sought.

A Burkholderia Type VI Effector Deamidates Rho GTPases to Activate the Pyrin Inflammasome

Burkholderia cenocepacia is an opportunistic pathogen of the cystic fibrosis lung that elicits a strong inflammatory response. B. cenocepacia employs a type VI secretion system (T6SS) to survive in macrophages by disarming Rho-type GTPases, causing actin cytoskeletal defects. Here, we identified TecA, a non-VgrG T6SS effector responsible for actin disruption. TecA and other bacterial homologs bear a cysteine protease-like catalytic triad, which inactivates Rho GTPases by deamidating a conserved asparagine in the GTPase switch-I region. RhoA deamidation induces caspase-1 inflammasome activation, which is mediated by the familial Mediterranean fever disease protein Pyrin. In mouse infection, the deamidase activity of TecA is necessary and sufficient for B. cenocepacia-triggered lung inflammation and also protects mice from lethal B. cenocepacia infection. Therefore, Burkholderia TecA is a T6SS effector that modifies a eukaryotic target through an asparagine deamidase activity, which in turn elicits host cell death and inflammation through activation of the Pyrin inflammasome.

Substance Use and Misuse : Adolescent Substance Use in the context of the family ; a qualitative study of young people's views on parent child attachments , parenting style and parental substance use

Introduction and Aims. While the role of the family in adolescent substance use has been well documented, few studies have attempted to explore in-depth youth perceptions of how these familial processes/dynamics influence teenage substance use. This paper reports the findings from a study exploring risk and protective factors for teenage substance use within the context of the family as perceived by young people with a view to informing current and future family based prevention and education interventions.
Design and Methods. Data collection took place in nine post-primary schools across Northern Ireland. Nine focus groups using participatory techniques were facilitated with a purposive sample of sixty-two young people (age 13-17 years). Data were transcribed verbatim and analysed using a content/thematic analysis.
Results. Three broad themes/aspects of the family emerged from the data, which may serve to protect or attenuate the risk of substance use among young people. Parent-child attachment was a major theme identified in protecting adolescents from substance use in addition to effective parenting particularly an authoritative style of parenting supplemented by parental monitoring and good parent-child communication to encourage child disclosure. Family substance use was deemed to impact on children’s substance use if exposed at an early age and the harms associated with PSM were discussed in detail.
Discussion and Conclusions. The qualitative approach provides insight into current understanding of youth perceptions of substance use in the context of family dynamics. A number of recommendations are outlined. Family based (preventive) interventions/parenting programmes may benefit from components on effective parenting including authoritative styles, parental monitoring, effective communication, spending time together (building attachments), parent-child conflict, adolescent development and factors which impact on parenting. Parenting programmes tailored to mothers and fathers may be beneficial. School based interventions targeting children/adolescents may be best placed to target children living with parental substance misuse.

The effectiveness, acceptability and cost-effectiveness of psychosocial interventions for maltreated children and adolescents: An evidence synthesis

DESIGN We will address our research objectives by searching the published and unpublished literature and conducting an evidence synthesis of i) studies of the effectiveness of psychosocial interventions provided for children and adolescents who have suffered maltreatment, ii) economic evaluations of these interventions and iii) studies of their acceptability to children, adolescents and their carers. SEARCH STRATEGY: Evidence will be identified via electronic databases for health and allied health literature, social sciences and social welfare, education and other evidence based depositories, and economic databases. We will identify material generated by user-led,voluntary sector enquiry by searching the internet and browsing the websites of relevant UK government departments and charities. Additionally, studies will be identified via the bibliographies of retrieved articles/reviews; targeted author searches; forward citation searching. We will also use our extensive professional networks, and our planned consultations with key stakeholders and our study steering committee. Databases will be searched from inception to time of search. REVIEW STRATEGY Inclusion criteria: 1) Infants, children or adolescents who have experienced maltreatment between the ages of 0 17 years. 2) All psychosocial interventions available for maltreated children and adolescents, by any provider and in any setting, aiming to address the sequelae of any form of maltreatment, including fabricated illness. 3) For synthesis of evidence of effectiveness: all controlled studies in which psychosocial interventions are compared with no-treatment, treatment as usual, waitlist or other-treated controls. For a synthesis of evidence of acceptability we will include any design that asks participants for their views or provides data on non-participation. For decision-analytic modelling we may include uncontrolled studies. Primary and secondary outcomes will be confirmed in consultation with stakeholders. Provisional primary outcomes are psychological distress/mental health (particularly PTSD, depression and anxiety, self-harm); ii) behaviour; iii) social functioning; iv) cognitive / academic attainment, v) quality of life, and vi) costs. After studies that meet the inclusion criteria have been identified (independently by two reviewers), data will be extracted and risk of bias (RoB) assessed (independently by two reviewers) using the Cochrane Collaboration RoB Tool (effectiveness), quality hierarchies of data sources for economic analyses (cost-effectiveness) and the CASP tool for qualitative research (acceptability). Where interventions are similar and appropriate data are available (or can be obtained) evidence synthesis will be performed to pool the results. Where possible, we will explore the extent to which age, maltreatment history (including whether intra- or extra-familial), time since maltreatment, care setting (family / out-of-home care including foster care/residential), care history, and characteristics of intervention (type, setting, provider, duration) moderate the effects of psychosocial interventions. A synthesis of acceptability data will be undertaken, using a narrative approach to synthesis. A decision-analytic model will be constructed to compare the expected cost-effectiveness of the different types of intervention identified in the systematic review. We will also conduct a Value of information analysis if the data permit. EXPECTED OUTPUTS: A synthesis of the effectiveness and cost effectiveness of psychosocial interventions for maltreated children (taking into account age, maltreatment profile and setting) and their acceptability to key stakeholders.

Família e aconselhamento genético: o caso dos cancros hereditários

Os desenvolvimentos associados à medicina genómica e biologia molecular representam novas possibilidades no diagnóstico, tratamento e prevenção de doenças comuns, confrontando indivíduos e famílias com complexos desafios à integração da informação genética na gestão da saúde e nas suas vidas. Este estudo centra-se em famílias com suscetibilidade genética acrescida a cancros hereditários e pretende contribuir para o conhecimento da experiência individual e familiar do aconselhamento oncogenético, incluindo como pode ser contemplada no desenvolvimento de intervenções de apoio psicossocial e na organização dos cuidados de saúde na era (pós)genómica. O processo de investigação incorpora perspetivas da genética psicossocial e da teoria dos sistemas familiares. Engloba metodologias qualitativas de recolha e análise de dados, envolvendo indivíduos, famílias e profissionais de saúde num formato de investigação-ação participativa. Os principais resultados permitem: i) conceptualizar a experiência do aconselhamento oncogenético, através da caracterização das suas implicações instrumentais, emocionais, relacionais e desenvolvimentais para o indivíduo e sistema familiar; ii) conhecer o desenvolvimento, implementação e avaliação de um programa psicoeducativo multifamiliar, enquanto intervenção de apoio psicossocial a indivíduos com suscetibilidade acrescida a cancros hereditários e suas famílias; e iii) integrar a perspetiva dos profissionais de saúde quanto à incorporação de apoio psicossocial na provisão dos serviços oncogenéticos. As conclusões gerais sustentam a importância do aprofundamento da pesquisa sobre o funcionamento familiar face ao aconselhamento e risco oncogenético, e a incorporação de uma orientação familiar nesses serviços. As implicações decorrentes da suscetibilidade acrescida a doenças genéticas impõem uma discussão alargada aos vários agentes envolvidos no planeamento, provisão e utilização dos cuidados de saúde, no sentido do desenvolvimento de serviços atuantes no continuum biopsicossocial indivíduofamília- sistema de saúde-comunidade.

Gerações de ecrã em meio rural : estudo dos novos media no quotidiano rural português de três gerações

Desde finais da década de 50, com o aparecimento e progressiva disseminação da televisão pelas casas portuguesas (atualmente, numa parte significativa delas, existe em mais do que um compartimento); passando pelo computador, na década de 70; e, finalmente, a forma como, na década de 90, se iniciou o processo de distribuição do telemóvel, há toda uma história associada sobre a qual é importante refletir. No meio rural português, qual foi o caminho traçado pelos seus residentes até à “domesticação” (Berker, Hartmann, Punie, & Ward, 2005; Silverstone, Hirsch, & Morley, 1992) de cada um dos media – televisão, computador e telemóvel? Da utilização quase exclusiva em espaços públicos até à sua integração no espaço doméstico e nas dinâmicas familiares e sociais, houve um percurso percorrido quer pelos media, que vão sofrendo alterações constantes, quer pelos indivíduos que se vão adaptando a essas alterações, mas também exigindo que os primeiros se vão moldando às suas necessidades e exigências, fazendo, por isso, que nunca percam o epíteto de “novo”. A existência dos meios digitais tem ainda outras particularidades associadas: a sua presença diária e transversal em todos os contextos nos quais os indivíduos estão habitualmente inseridos – familiar, laboral/escolar e de lazer -, a ocorrência em todas as gerações familiares e, consequentemente, de um modo generalizado, em todas as idades. Os avós, os pais (e, ao mesmo tempo, filhos) e os filhos (e, ao mesmo tempo, netos) fazem uma utilização mais ou menos frequente, mas que não é inexistente, originando, por isso, a designação de gerações de ecrã. Interessa, pois, fazer o estudo dos usos e apropriações dos novos media pelas diferentes gerações, para uma análise intergeracional, mas, mais ainda, compreender as implicações que esses usos têm no meio rural, por ser fortemente considerado como uma zona em desvantagem quanto à proliferação dos media e das tecnologias de informação e comunicação, quando comparada com a urbana. Apresenta-se uma análise e reflexão sobre o modo como os novos media penetraram no quotidiano de três gerações familiares (avós, pais e filhos) e na forma como estas, residentes no meio rural português, transformaram a apropriação dos media num ato contínuo. Esta análise e reflexão fundamentam-se no levantamento bibliográfico sobre a problemática e os dados empíricos obtidos através da aplicação de uma metodologia triangular: focus groups, diários e inquéritos por questionário.

(Re)configuração das práticas educativas na prevenção do stresse na infância

O presente trabalho resulta do estudo que procurou analisar a reconfiguração das práticas educativas na prevenção do stresse na infância. O principal objetivo foi o de analisar de que forma os educadores podem desenvolver práticas educativas, estruturadoras e estruturantes do bem-estar da criança, investindo intencionalmente no desenvolvimento de atividades educativas, de modo a prevenir os índices de stresse das crianças, na educação pré-escolar. Foram realizados cinco estudos complementares, de natureza quantitativa e qualitativa. O estudo 1: contextualização e caracterização de indicadores sociofamiliares de crianças que frequentam a educação pré-escolar; Estudo 2: adaptação/avaliação do PKBS-2 de Merrell, para identificação das aptidões sociais e os problemas de comportamento em crianças dos 3 aos 6 anos numa amostra portuguesa (N=150) e estudos comparativos Portugal/Brasil (N=300) e Portugal/Cabo-Verde (N=150); Estudo 3: validação da Escala Comportamental para crianças em idade Pré-Escolar – PKBSpt, versão portuguesa do PKBS-2 em crianças dos 2 aos 7 anos (N=581); Estudo 4: contributos para a reconfiguração das práticas pedagógicas e o stresse na infância sob o olhar dos educadores. No âmbito deste estudo 4, desenvolvemos e validamos o Protocolo para a Avaliação do Stresse na Infância–PASI, constituído por três subescalas que aplicamos a educadores ou equiparados (N=188): ESISI, EPELSI e ECPLSI; Estudo 5: análise das competências dos profissionais da educação ao nível da ansiedade (IAB de Beck) e estratégias de coping; (EC de Gomes & Pereira). Para análise estatística dos dados utilizamos o programa SPSS e o Excel. Os resultados evidenciaram a validade e fidelidade dos instrumentos: ESISI, EPELSI, ECPLSI e PKBSpt, bem como a validação para a língua portuguesa deste último. A variável género apresentou diferenças estatisticamente significativas nas aptidões sociais e problemas de comportamento, no entanto não estão correlacionadas com os problemas de ansiedade. Os Educadores focalizam a sua praxis educativa na observação, identificação e definição de estratégias orientadas para o stresse na infância e, ainda, na cooperação escola/família e na prevenção das situações indutoras de stresse. Contudo apontam algumas fragilidades na formação básica e contínua, para lidarem com o stresse na primeira infância. As causas psicossociais são preditoras das situações indutoras de stresse na infância e são explicadas pelas causas externas de componente escolar, ou seja, as perturbações de ansiedade na infância poderão ter repercussões no contexto escolar. Importa que a comunidade educativa perspetive particular atenção às crianças que estão em situação de maior vulnerabilidade, de modo a prevenir e a intervir nas situações de stresse na educação pré-escolar. São referidas implicações psicopedagógicas deste estudo.
