ABSTRACT
AIMS: The role of relaxin-2 as a circulating marker in heart failure (HF) with preserved ejection fraction (HFpEF) is poorly understood. We aimed to characterize relaxin-2 circulating levels in a population of chronic HFpEF patients and their association with long-term prognosis. METHODS: Relaxin-2 serum levels were measured in 85 chronic HFpEF patients from a prospective cohort study (NETDiamond). Clinical, imaging, and analytical data were compared across relaxin-2 tertiles. The primary outcome was a composite of cardiovascular death, HF hospitalisation, acute HF episode or diuretic intensification and the secondary outcome a composite of cardiovascular death and total HF hospitalisations. Cox regression and negative binomial models were used to assess the relation between relaxin-2 and the outcomes. RESULTS: Relaxin-2 levels were positively associated with left atrial volume, left ventricular mass and peripheral oedema, and negatively associated with ischemic heart disease and statin use. Higher relaxin-2 levels were associated with an increased risk of primary outcome, even after adjustment for age, B-type natriuretic peptide (BNP) and glomerular filtration rate (eGFR) (adjusted HR = 2.80, 95%CI 1.4-7.3, p = 0.034 for tertile 3). They were also associated with the occurrence of the secondary outcome (Incidence Rate Ratio = 5.28, 95%CI 1.2-23.2, p = 0.027), but this significance was lost when simultaneously adjusted for BNP and eGFR. CONCLUSION: In chronic HFpEF patients, higher relaxin-2 circulating levels were associated with left chambers remodelling, congestion, and adverse prognosis. These findings support a potential role for relaxin-2 as a pathophysiological agent and as a circulating biomarker in HFpEF.

INTRODUCTION: The Centro de Estudos do Bebé e da Criança in Hospital Dona Estefânia has organized a multidisciplinary model for children under three with suspected autism spectrum disorder, thus implementing the recent guidelines established by the Directorate General for Health. The aim of this study is to describe this model and case series. MATERIAL AND METHODS: A retrospective descriptive study of observed children with suspected ASD. They were observed according to the model of the Centro de Estudos do Bebé e da Criança and DC:0-5TM classification, between January 2018 and September 2019. RESULTS: The study included 178 children. The average age at the initial assessment was 27 months. From the total sample, 116 children concluded the diagnostic sessions (axis I): Autism Spectrum Disorder/Early Atypical (36%), Developmental Language Disorder (18%), Other (19%). Factors of axes II, III, IV and V of DC:0-5TM were determinant for clinical diagnosis in 26%. DISCUSSION: Of 116 children, 36% were diagnosed with Autism Spectrum Disorder. This highlights the diagnostic challenge posed by neurodevelopmental disorders in early infancy. The sample shows that the characteristics of the relationship with the caregiver (axis II), presence of physical conditions (axis III), psycho-social stressors (axis IV) and developmental trajectory (axis V) have a significant clinical impact. In the future, the initial assessment should take place well before the age of 27 months because of the impact on prognosis. CONCLUSION: This model is a pioneering approach in Portugal. It promotes a common approach of Child and Adolescent Psychiatry and Neuropediatrics/Developmental Pediatrics in early infancy. Moreover, it increases the diagnostic acuity of Autism Spectrum Disorders and early therapeutic intervention.
Introdução: O Centro de Estudos do Bebé e da Criança do Hospital Dona Estefânia desenvolveu um modelo multidisciplinar de atuação na suspeita de perturbação do espetro do autismo na primeira infância, aplicando a recente norma da Direção Geral da Saúde. Pretende-se descrever a sua apresentação e casuística.Material e Métodos: Estudo retrospetivo descritivo da série de crianças(< 3 anos), observadas por suspeita de perturbação do espetro do autismo, entre janeiro de 2018 e setembro de 2019, segundo este modelo e a classificação DC:0-5TM.Resultados: Foram observadas 178 crianças. A idade média da primeira consulta foi de 27 meses. Do total de crianças observadas, 116 concluíram as sessões diagnósticas (diagnóstico eixo I): perturbação do espetro do autismo/ perturbação do espetro do autismo atípica precoce (36%), perturbação do desenvolvimento da linguagem (18%), outros(19%). Em 26% dos casos, o quadro foi atribuído a fatores classificados em outros eixos.Discussão: O diagnóstico de perturbação do espetro do autismo foi colocado em 36%, demonstrando o desafio diagnóstico das perturbações do neurodesenvolvimento na primeira infância. A casuística demonstra ainda que as características da relação com o cuidador (eixo II), a presença de condições físicas (eixo III), fatores de stress psicossociais (eixo IV) e a trajetória de desenvolvimento (eixo V) têm um impacto clínico significativo. É desejável a antecipação da idade de sinalização pelo impacto no prognóstico.Conclusão: Este modelo é pioneiro em Portugal ao propor uma atuação conjunta de duas especialidades na primeira infância: pedopsiquiatria e neuropediatria/pediatria desenvolvimento. Este modelo de atuação melhora a acuidade diagnóstica e permite a intervenção terapêutica precoce.

This study focuses on mothers of children diagnosed with attention deficit/hyperactivity disorder (ADHD) and sets out (1) to characterize dimensions of both parental functioning (parenting stress and parental practices) and child characteristics (behaviour) and (2) to determine predictors of parenting stress, namely parental rearing practices or perceived behaviour of the child, in order to plan intervention with the families. Fifty-two mothers of children diagnosed with ADHD and aged 6-12 years participated in the study. The Portuguese versions of the Parenting Stress Index (Abidin and Santos 2003), EMBU-P (Canavarro and Pereira 2007) and Child Behaviour Checklist (Albuquerque et al. 1999) were used. Results showed that mothers of children with ADHD experience higher levels of parenting stress (emerging essentially from the child's characteristics) and report more behavioural problems in their children (for girls and boys), but use parental practices similar to those of the mothers of the Portuguese validation sample. Results also indicate that child behaviour (both internalized and externalized) and parental practices dominated by rejection predict parenting stress. These findings have implications for intervention with children diagnosed with ADHD and their families.

Mental retardation (MR) consists of a sub average general intellectual functioning (IQ < 70) that is associated with significant limitations in adaptative functioning which begins before age 18 years (DSM IV). It's our intention to characterize the children's population with MR observed at the Dona Estefânia Hospital Development Center, trough a retrospective study of the children which were assessed between January 2005 and June 2007. Epidemiologic data, like the severity of DM, organic aetiologies, co-morbidity and therapeutical and educational intervention, were the parameters evaluated. There were 232 children assessed and 185 had MR, mainly boys (58%): 112 (46%) had mild MR, 54 (29%) had moderate MR, 17 (9%) had severe DM and 2 (1%) profound MR. Aetiologies were defined on 86 children (46%); the highest rate of diagnosis occurred on the most severe cases of MR. The aetiologies most frequently found were the genetic diseases, prematurity and associated comorbidity, with high variety of aetiologies. Co-morbidity was detected on 123 children (66%), being the most frequent the ophthalmologic (57 children, 46%). The totality of children with MR were proposed for early intervention (47%) and special education (58%). The data obtained from the clinical and functional characterization of the children accompanied by the Development Center of Dona Estefânia Hospital with MR diagnosis was similar to the data described in literature. However, some data differ from other case series due, among other things, to etiological group differences, different age groups and different assistential politics.
