Repercussions of the COVID-19 pandemic on child and adolescent mental health: A matter of concern-A joint statement from EAP and ECPCP.

COVID-19 pandemic and the consequent rigid social distancing measures implemented, including school closures, have heavily impacted children's and adolescents' psychosocial wellbeing, and their mental health problems significantly increased. However, child and adolescent mental health were already a serious problem before the Pandemic all over the world. COVID-19 is not just a pandemic, it is a syndemic and mentally or socially disadvantaged children and adolescents are the most affected. Non-Communicable Diseases (NCDs) and previous mental health issues are an additional worsening condition. Even though many countries have responded with decisive efforts to scale-up mental health services, a more integrated and community-based approach to mental health is required. EAP and ECPCP makes recommendations to all the stakeholders to take action to promote, protect and care for the mental health of a generation.

Experiência inicial com o implante percutâneo da valva Venus-P valve® no trato de saída nativo pulmonar / Initial experience with percutaneous Venus-P Valve® valve implantation in the native pulmonary outflow tract

INTRODUÇÃO: O restabelecimento da função valvar pulmonar com implante percutâneo de próteses atualmente é realizado somente nos pacientes portadores de biopróteses, condutos ou homoenxertos posicionados na via de saída do VD. Próteses dedicadas para tratos de saída nativo estão sendo estudadas e implantadas com sucesso em diversos centros mundiais. OBJETIVOS: Apresentar a experiência inicial do implante percutâneo da VENUS-P Valve® em trato de saída nativo pulmonar. Serão demonstrados critérios de escolha dos pacientes, aspectos técnicos relacionados aos procedimentos e resultados de curto prazo. MATERIAIS E MÉTODOS: A prótese VENUS-P Valve® (Venus Medtech, Shanghai) é um stent de nitinol autoexpansível com uma valva de pericárdio porcino montada no seu interior. Possui aspecto de ampulheta e na extremidade distal o stent é de células abertas permitindo o fluxo para ambas artérias pulmonares. O seu sistema de entrega é 22 ou 24F. Os pacientes candidatos são avaliados com ecocardiografia transtorácica, angiotomografia, ressonância magnética e cateterismo cardíaco. São critérios de inclusão a presença de regurgitação pulmonar importante, com volumes diastólicos do VD>130ml/m2, sem estenoses na VSVD ou ramos pulmonares e trato de saída com no máximo 35mm de diâmetro após insuflação de cateter-balão medidor. O ecocardiograma transtorácico é o método padrão de escolha do diâmetro e comprimento da prótese. Todos os procedimentos foram realizados em sala híbrida, com anestesia geral endovenosa, profilaxia para endocardite bacteriana e heparina (TCA>250 seg). Os pacientes realizaram ecocardiografia transtorácica e avaliação clínica 24 horas e 30 dias após os procedimentos. RESULTADOS: Quatro pacientes (3 homens) foram submetidos ao implante percutâneo das valvas pulmonares em 2 dias consecutivos. O peso e idade médio foi de 62,2kg e 25,8 anos. A via de saída teve 30mm em média e a prótese utilizada apresentou diâmetro médio de 32mm. Três próteses tinham 25 mm de comprimento e a última 30mm. Houve sucesso no implante de todos os dispositivos com restabelecimento imediato da função valvar pulmonar. Uma prótese foi considerada em posição mais baixa no trato de saída porém sem interferência em estruturas cardíacas. Ao ecocardiograma de controle todos os dispositivos encontravam-se sem refluxo significativo, com fluxo preservado para as artérias pulmonares bilaterais e sem complicações relacionadas. Não houve complicações ou óbitos relacionados aos procedimentos. CONCLUSÕES: O restabelecimento da função valvar pulmonar em pacientes com trato de saída nativo com o implante percutâneo da VENUS-P Valve® mostrou-se uma excelente alternativa nesta experiência inicial. Os procedimentos são factíveis e seguros quando realizados por grupos experientes e familiarizados com o implante de stents na via de saída pulmonar. Por tratar-se de experiência inicial, acreditamos que um maior número de implantes e análise dos resultados tardios devem ser realizadas para incorporação definitiva destes dispositivos neste grupo selecionado de pacientes.

Neurodegeneration by polyglutamine Atrophin is not rescued by induction of autophagy.

Polyglutamine pathologies are neurodegenerative diseases that manifest both general polyglutamine toxicity and mutant protein-specific effects. Dentatorubral-pallidoluysian Atrophy (DRPLA) is one of these disorders caused by mutations in the Atrophin-1 protein. We have generated several models for DRPLA in Drosophila and analysed the mechanisms of cellular and organism toxicity. Our genetic and ultrastructural analysis of neurodegeneration suggests that autophagy may have a role in cellular degeneration when polyglutamine proteins are overexpressed in neuronal and glial cells. Clearance of autophagic organelles is blocked at the lysosomal level after correct fusion between autophagosomes and lysosomes. This leads to accumulation of autofluorescent pigments and proteinaceous residues usually degraded by the autophagy-lysosome system. Under these circumstances, further pharmacological and genetic induction of autophagy does not rescue neurodegeneration by polyglutamine Atrophins, in contrast to many other neurodegenerative conditions. Our data thus provide a crucial insight into the specific mechanism of a polyglutamine disease and reveal important differences in the role of autophagy with respect to other diseases of the same family.

[Epidemiologic correlation between microhematuria in children and hypertension in their parents]. / Correlazione epidemiologica fra microematuria nei bambini ed ipertensione nei genitori.

The significance of asymptomatic microhematuria in children is unknown. In 1976 Dodge et al. found a "surprising" high prevalence of proteinuria and haematuria in 12,000 healthy schoolchildren and, in the absence of knowledge of the natural history, this finding prompted them to postpone urinary mass screening. Nonetheless, the progressive course of most chronic renal disease in adulthood argues for investigation of microhematuria in children to uncover any sub-groups "at risk" of kidney diseases. The sensitivity of screening for microhematuria could be increased by a questionnaire on family medical history? We have investigated 1554 boys and 1484 girls aged 3-12 years, from the school population of a rural district near Rome. A self-administered questionnaire on renal disease and related symptoms in families was distributed to the parents. Urinalyses were done on all the children except for those with diseases or symptoms related to the urinary apparatus and girls who were menstruating. Haematuria was tested for by dipstick ("Combur 7"; Boehringer), children with microhematuria were retested 10 day and 1 year later. On the initial 3038 dipstick tests 175 (5.76%) were positive, and 52 children (1.71%) had haematuria in all three specimens. The questionnaires were used only if they had been filled in properly (1821/3038). Of the 1821 valid questionnaires 121 (6.64%) revealed a family history of hypertension, but the frequency of such a family history was significantly higher for the 128 children with haematuria (14.8%, p < 0.005) and the 52 with persistent haematuria (23.0%; p < 0.001).

Atopy and environmental factors in upper respiratory infections: an epidemiological survey on 2304 school children.

Upper respiratory infections (URI) during the first years of life are mostly viral in origin. However, a number of observations suggest the influence of both predisposing and triggering factors. Atopy in particular seems to play an important role as do environmental factors. Many children with early symptoms such as blocked or runny nose are likely to become skin-positive later in life to antigens such as, e.g., D. pteronissinus. A standardized questionnaire was administered to 2304 schoolchildren in order to ascertain the URI frequency and to correlate it with family and environmental factors and with results of prick tests for main allergens in our climate (D. pteronissinus and Grasses). Results showed a wide overlapping of URI and lower respiratory illnesses (in particular, asthma), which are widely distributed in the families of patients. Passive smoking and the quality of housing are the main triggering environmental factors. In our sample, skin positivity for D. pteronissinus and Grasses largely exceeds the symptomatic portion of the whole population. It is therefore suggested that many asymptomatic children are "at risk" for allergic respiratory illness. The highest incidence of winter rhinitis in skin-negative subjects (71.7%) and the skin positivity for D. pteronissinus in patients with perennial symptoms, suggest the importance of both atopy and viral infections in the occurrence of URI. Nasal troubles are most frequent in asthmatic subjects and may be considered the actual additional symptom in asthma.

Evaluating bronchial hyperreactivity tests in epidemiology.

The aim of this study is to assess the value of the most common tests which can be used in epidemiological surveys to identify asthmatic children. We reviewed anamnestic information from a self-administered questionnaire, bronchial reactivity by means of exercise-test, bronchodilation-test with trimethochinol, carbachol-test (PD20 FEV1 was reported), cutaneous reactivity monitored by prick-test. (Data from a polycentric epidemiological study). We conclude that, while these tests are very useful in the initial study and in the further follow-up of the asthmatic child, providing also information about the possibilities of management of bronchoconstriction and its pharmacologic prevention, they show a limited value in the absolute diagnosis of asthma.
