- Ansiedade, Funcionamento Familiar e Biomarcadores Neuroendócrinos em Crianças ObesasPublication . Pinto, I; Wilkinson, S; Virella, D; Alves, M; Calhau, C; Coelho, RINTRODUCTION: This observational study explores potential links between obese children's cortisol, and parental mental state, family functioning, and the children's symptoms of anxiety and depression. MATERIAL AND METHODS: A non-random sample of 104 obese children (55 boys), mean age 10.9 years (standard deviation 1.76), was recruited from a childhood obesity clinic. Obesity was defined as body mass index above the 95th age- and gender-specific percentiles. Neuroendocrine biomarkers were measured. Symptoms of anxiety and depression were assessed with self and parent-reported questionnaires (Anxiety, Depression and Stress Scales; Child Behaviour Checklist). Family functioning was assessed with parent-reported questionnaires (Family Adaptation and Cohesion Scales-III). RESULTS: A significant, negative correlation (rs = -0.779; p = 0.003) between girls' cortisol and their parents' anxiety symptoms was found, limited to high functioning families. Boys scored significantly higher than girls on parent-reported internalizing symptoms but not on self-report. No association was found between cortisol in children and parental depressive symptoms. DISCUSSION: Whether the association between cortisol levels in obese children and parental mental health is effectively restricted to girls from high functioning families or is due to study limitations, requires further research. The lack of associations between cortisol in children and parental depressive symptoms, suggests a specific association between cortisol and parental anxiety symptoms. CONCLUSION: These results highlight the importance of taking into account family functioning, parental mental state and gender, when investigating neuroendocrine biomarkers in obese children associated with symptoms of anxiety and depression.
- Attachment, Physiological and Familial Vulnerability in Childhood Obesity: an Interactive Multisystem ApproachPublication . Pinto, I; Oliveira, L; Pinto, M; Calhau, C; Coelho, RThe aims of the present study were to test the association between insecure attachment and basal cortisol and catecholamines levels in a sample of obese children. The role of familial vulnerability and gender was also investigated. Methods: Cortisol and catecholamines levels of 8- to 13-year olds obese children were measured. Self-report questionnaires were used to assess attachment pattern and current anxiety and depression, and parent-report questionnaires were used to assess attachment, current anxiety and depression and familial vulnerability. Linear regression analyses were performed for individuals that scored low versus high on parental internalizing problems, and for boys and girls, separately. Results: In the group with high parental internalizing problems, insecure attachment was significantly associated with reduced basal levels of cortisol, in boys (p=0.007, b= -0.861, R2= 73.0%). In the group with low parental internalizing problems, the association between insecure attachment and cortisol was not significant in either boys or girls, and it was negative in boys (p=0.075, b= -0.606, R2= 36.7%) and positive in girls (p=0.677, b= 0.176, R2= 3.1%) . Conclusions: Apparently, physiological risk factors for psicopathology in obesity are more evident in individuals with a high familial vulnerability. In addition, patterns of physiological risk for psicopathology in obesity are different in boys and girls. Therefore, it is important to take into account familial vulnerability and gender when investigating physiological risk factors for psycopathology in obesity. Insecure attachment in childhood may be a risk factor for obesity. Interventions to increase children's attachment security should examine the effects on children's weight.

- Necrotizing Fasciitis Caused by Photobacterium damselae: The First Case in PortugalPublication . Guimarães, D; Ribeiro, L; Vieira, L; Coelho, RNecrotizing fasciitis is a severe soft tissue infection with a high mortality rate and therefore requires emergent surgical treatment. Several microorganisms can cause this infection, Photobacterium damselae being one of them, with only eight cases previously published in the literature. We report the first ever case of necrotizing fasciitis, caused by this microorganism, in Portugal. In this case report the patient survived after several debridement procedures and reconstruction of the upper limb with acellular dermal matrix and skin graft. A brief review of the Photobacterium damselae soft tissue infection reports as well as the clinical presentation, diagnosis, pathophysiology and treatment of necrotizing fasciitis can also be found in this paper.

- Prediction of Severe Exacerbations and Mortality in COPD: the Role of Exacerbation History and Inspiratory Capacity/Total Lung Capacity RatioPublication . Cardoso, J; Coelho, R; Rocha, C; Coelho, C; Semedo, L; Bugalho Almeida, ABACKGROUND: Severe exacerbations and mortality are major outcomes in COPD, and risk factors for these events are actively searched for. Several predictors of mortality have been identified in COPD. The inspiratory capacity/total lung capacity (IC/TLC) ratio has been shown to be a strong predictor of all cause and respiratory mortality in patients with COPD. The major objectives of this study were to analyze which clinical parameters, including lung volumes, were the best predictors of the 5-year cumulative risk of hospital admissions or death and the 5-year risk of exacerbations, in stable COPD patients. METHODS: This study retrospectively reviewed data from 98 stable COPD patients, consecutively recruited in 2012. Forced expiratory volume in 1 s (FEV1), modified Medical Research Council dyspnea scale, exacerbation history (ExH), Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2011 groups, and lung volumes were reviewed. Five years later, this population was evaluated for cumulative exacerbations, hospital admissions, and mortality. All the population, and GOLD group D separately, were analyzed. RESULTS: The cumulative 5-year combined risk of hospital admission or death was significantly predicted by the ExH and the IC/TLC ratio. Analyzing separately group D, FEV1 was the only predictor of this outcome. The frequency of exacerbations in the previous year was the best predictor of future cumulative 5-year risk of subsequent exacerbations, both for the total population and the GOLD D group. CONCLUSION: ExH and IC/TLC ratio were the best predictors of the most severe outcomes in COPD (admissions or mortality), independently of COPD severity. FEV1 was the only predictor of the cumulative 5-year combined risk of hospital admission or death in the GOLD D group. ExH was the best predictor of 5-year cumulative future risk of exacerbations. Besides FEV1 and ExH, the IC/TLC ratio can be a useful predictor of severe outcomes in COPD.

- Soluble Human Suppression of Tumorigenicity 2 Is Associated with Endoscopic Activity in Patients with Moderate-to-Severe Ulcerative Colitis Treated with GolimumabPublication . Magro, F; Lopes, S; Silva, M; Coelho, R; Portela, F; Branquinho, D; Correia, L; Fernandes, S; Cravo, M; Caldeira, P; Tavares de Sousa, H; Patita, M; Lago, P; Ramos, J; Afonso, J; Redondo, I; Machado, P; Philip, G; Lopes, J; Carneiro, FBackground: Suppressor of Tumorigenicity 2 (ST2) is an IL33 receptor detected in the mucosa and serum of ulcerative colitis (UC) patients. We evaluated soluble ST2 (sST2) as a surrogate biomarker of disease outcome and therapeutic response, in moderate-to-severe UC patients treated with golimumab. Methods: We conducted an open-label single-arm multicentre prospective study. At screening/baseline, week 6 (W6) and week 16 (W16), clinical and endoscopic activity (total Mayo score), histologic activity (Geboes index) and biomarkers were evaluated. Results: From 38 patients, 34 (89.5%) completed W6 and 29 (76.3%) completed W16. Mean age (±SD) was 34.6 ± 12.6 years; 55.9% were female. At W16, 62.1% achieved clinical response. Patients with endoscopic activity at W6 (n = 20) had higher baseline sST2 (median, 24.5 versus 18.7 ng/ml, p = 0.026) and no decrease from baseline (median change, 0.8 versus -2.7, p = 0.029). At W6, sST2 levels correlated with endoscopic activity (rs = 0.45, p = 0.007) but not with histological activity (rs = 0.25, p = 0.151). The best cut-offs for endoscopic activity were sST2 = 16.9 ng/ml (sensitivity = 85%; specificity = 71%) and faecal calprotectin (FC) = 353 μg/g (sensitivity = 90%, specificity = 67%). Patients with histological activity at W6 (n = 27) had higher baseline ST2 levels (median, 23.0 versus 13.7 ng/ml, p = 0.035). sST2 did not correlate with FC or serum C-reactive protein. FC levels correlated with histological activity and baseline FC were higher when Geboes ⩾3.1 at W6. Conclusions: sST2 may be a surrogate biomarker of UC activity and therapeutic response as it correlates with endoscopic and clinical activity at W6 of golimumab treatment, and subjects with endoscopic and histological activity at W6 had higher baseline ST2 levels.

- Telangiectasia Macularis Eruptiva Perstans. Resposta à Terapêutica com Fotoquimioterapia SistémicaPublication . Amaro, C; Medeiros, S; Coelho, R; Afonso, A; Marques Pinto, GA telangiectasia macularis eruptiva perstans (TMEP) é um subtipo raro de mastocitose cutânea, ocorrendo tipicamente em adultos. Distingue-se das outras formas cutâneas por ser, caracteristicamente, refractária às terapêuticas instituídas e pela ausência de associações sistémicas. Descreve-se o caso de um doente de 47 anos de idade com diagnóstico de TMEP submetido a terapêutica com PUVA com redução da extensão da dermatose e considerável diminuição do prurido associado, após 2 ciclos de tratamento.
