Tentativas de SuicĂdio em Adolescentes Internados na Unidade de Internamento de Pedopsiquiatria do Centro Hospitalar de Lisboa Central.
Os Comportamentos Auto-Destrutivos (CAD) designam todos os comportamentos que pĂ”em em causa a integridade fĂsica de um indivĂduo. Quando associados a uma intenção de morrer fala-se de Tentativa de SuicĂdio (TS), sendo esta o factor preditor mais importante de risco de suicĂdio, que nos EUA Ă© a 3ÂȘ causa de morte entre os adolescentes. Na
adolescĂȘncia, as TS sĂŁo mais frequentes no gĂ©nero feminino e os suicĂdios no masculino, concorrendo para tal uma sĂ©rie de
factores biopsicossociais. O presente estudo retrospectivo observacional pretende, assim, caracterizar a população de adolescentes internados no Internamento de Pedopsiquiatria
do CHCL por TS, entre Janeiro de 2006 e Fevereiro de 2009, atravĂ©s da recolha de dados demogrĂĄficos, clĂnicos e
psicopatolĂłgicos presentes nos processos clĂnicos
Tentativas de SuicĂdio em Adolescentes Internados na Unidade de Internamento de Pedopsiquiatria do Centro Hospitalar de Lisboa Central (CHLC) :Janeiro de 2006 a Fevereiro de 2009
Resilience in Institutionalized Children and Adolescents
Introdução: O conceito de resiliĂȘncia refere-se Ă possibilidade de os indivĂduos se desenvolverem favoravelmente quando expostos a situaçÔes de adversidade ou stress. Trata-se de um processo complexo que envolve a interacção entre factores de vulnerabilidade/risco e factores
de protecção. A investigação em resiliĂȘncia apenas tem interesse quando aplicada a contextos que pressuponham a existĂȘncia de uma população considerada de risco, mas que apresente tambĂ©m caracterĂsticas adaptativas como Ă© o caso das instituiçÔes de acolhimento de criançase adolescentes. Torna-se cada vez mais necessĂĄria a realização de estudos que permitam melhorar o conhecimento do funcionamento mental destas populaçÔes, para que possam ser criados programas de prevenção e promoção de saĂșde adequados. Objectivos: Identificar factores de
resiliĂȘncia e a sua associação com a presença de psicopatologia em crianças/adolescentes (C/A) de trĂȘs InstituiçÔes de Acolhimento da ĂĄrea da Grande Lisboa. Metodologia: Escolhemos, por
amostragem de conveniĂȘncia, trĂȘs instituiçÔes de acolhimento residencial de crianças/adolescentes da ĂĄrea da Grande Lisboa. SeleccionĂĄmos uma amostra de crianças/adolescentes de idades entre os 6 e os 18 anos (inclusivĂ©), com um perĂodo de institucionalização igual ou superior a 1
ano e com consentimento informado assinado pelos seus representantes legais. Foram excluĂdos as crianças/adolescentes com diagnĂłstico de Perturbação Global do Desenvolvimento (DSM-IV-TR). Os instrumentos de avaliação utilizados (Check-list para Caracterização da Criança/Adolescente, Instituição e Comunidade, e Child Behavior Checklist) foram preenchidos pelo
prestador de cuidados que melhor conhecia a crianças/ adolescentes. Resultados e ConclusĂ”es: Na amostra estudada, hĂĄ factores de resiliĂȘncia que estĂŁo ausentes nas crianças/ adolescentes que tĂȘm psicopatologia e estĂŁo presentes nas crianças/adolescentes sem problemas psicopatolĂłgicos. IdentificĂĄmos factores de resiliĂȘncia que parecem ter maior preponderĂąncia para a protecção da crianças/adolescentes, tais como âauto-estima positivaâ, âter talentos reconhecidos pelos outrosâ e âcompetĂȘncias cognitivasâ. O sexo masculino apresenta mais psicopatologia, a par da existĂȘncia de um menor nĂșmero de factores de resiliĂȘncia, relativamente ao sexo feminino
Correlates of children's physical activity during the COVID-19 confinement in Portugal
Objectives: The aim of the study was to understand the role of household variables on the percentage of
physical activity (%PA) during the coronavirus disease 2019 (COVID-19) confinement in Portugal.
Study design: A cross-sectional study design using an anonymous online survey was launched to assess
how Portuguese families with children aged younger than 13 years adjusted their daily routines to the confinement.
Methods: Separate analyses of variance were performed to investigate how factors such as the number of
children, age, sex, the housing characteristics, and the adults' job situation can affect the percentage of
time for PA (%PA).
Results: Findings, based on data from 2159 children, indicate that (1) boys and girls did not differ in the
%PA on any of the age-groups; (2) children with an outdoor space and who had other children in the
household were significantly more active (P < .001); (3) children from families with all adults working
from home showed lower levels of %PA; and (4) being younger, having a big outdoor space, having
other children in the household, and having at least one adult free from working from home were
significant positive predictors of children's %PA, explaining 21% of the overall variance.
Conclusion: Time allocated for PA during this period is reduced compared with what is usually reported
on normal days. It is necessary to find strategies to increase children's PA, especially in families in which
both parents are working and have no outdoor space.4811-99FE-2ECD | Luis Paulo RodriguesN/
Learning to cycle: from training wheels to balance bike
Background: Learning to cycle is an important milestone in a childâs life, so it is important to allow them to explore cycling as soon as possible. The use of a bicycle with training wheels (BTW) for learning to cycling is an old approach practiced worldwide. Most recently, a new approach using the balance bike (BB) has received increased attention, and several entities believe that this could be most efficient. Drawing on the work of Bronfenbrenner (1995) and Newel (1986), this study aimed to analyse the effect of BBâs use on the learning process of cycling independently. Methods: Data were collected in Portugal from an online structured survey between November 2019 and June 2020. Results: A total of 2005 responses were obtained for adults and children (parental response). Results revealed that when the BBâs approach was used, learning age (LA) occurred earlier (M = 4.16 ± 1.34 years) than with the BTWâs approach (M = 5.97 ± 2.16 years) (p < 0.001); or than when there was only the single use of the traditional bicycle (M =7.27 ± 3.74 years) (p < 0.001). Conclusions: Children who used the BB as the first bike had a significantly lower LA than children who did not use it (p < 0.001). To maximize its effects, the BB should be used in the beginning of the learning process.info:eu-repo/semantics/publishedVersio
Atrazine bound residues formation and dissipation in subtropical soil under swine wastewater application
The effects of swine wastewater on atrazine dissipation and formation of bound
residues in subtropical clay soil were investigated in this study. The experiment was carried out in
laboratory, under room conditions, where samples of Rhodic Hapludox soil received 168.61 mg kg-1
of atrazine and were incubated for 60 days in the following treatments: T1 (sterilized soil + swine
wastewater), T2 (sterilized soil + distilled water), T3 (Non sterilized soil + swine wastewater) and
T4 (Non sterilized soil + distilled water). The extractable residues and bound residues of atrazine
were extracted and analyzed by high performance liquid chromatography. The results showed no
effect of swine wastewater on atrazine dissipation. However, the addition of swine wastewater
favored the increase of bound residues, which can increase the persistence of atrazine in the
environment and reduce its bioavailabilityinfo:eu-repo/semantics/publishedVersio
Effects of the COVID-19 pandemic on preschool children and preschools in Portugal. Journal
Problem Statement:The COVID-19 pandemic led to significant changes in the life routines of preschool children, both during lockdown and post-lockdown periods. Approach:An online survey completed by parents, in-loco assessment scales filled in by a researcherand semi-structured interviews with preschool teacherswere used to investigate the effects of the adjustments, which occurred in preschool childrenâs lives, in the lockdown and post lockdown periods.Purpose:To characterize the levels of physical activity that Portuguese children had during the lockdown period and to understand what changed in their school routines in the post-lockdown period, regarding the organization of school spaces and routines.Results:Parents reported that children aged 3 to 5spent most of their time during lockdownundertaking sedentary activities (72% of their daily activities). In the post-lockdown period,results indicate that in June there was an increase in the number of preschools with a poor
quality of environment compared to the pre-pandemic period (October/November).Taking into account the measures implemented in preschools to prevent the COVID-19 transmission,teachers were of the opinion that limiting the number of children sharing material was the worst measure imposed, since it hampered childrenâs socialization. Conversely, increasing the use of the outdoor space was deemed positive because it improved childrenâs happiness and action possibilities outside.Conclusions: TheCOVID-19pandemic has had a clear impact on Portuguese childrenâs overall levels of physical activity during lockdown. In some schools, the implementation of health guidelines has also led to further negative effects on childrenâs play opportunities. However, many schools seem to be successful in finding strategies to ensure a healthy balance between
promoting childrenâs physical activity and ensuring risk control
