The cumulative effect of repeated asymptomatic enteric infections on intestinal barrier is not fully understood in infants. We aimed to evaluate the association between previous enteric parasitic infections and intestinal inflammation and permeability at 24-months of age, in asymptomatic infants of São Tomé Island. A subset of infants from a birth cohort, with intestinal parasite evaluations in at least four points of assessment, was eligible. Intestinal inflammatory response and permeability were assessed using fecal S100A12 and alpha-1-antitrypsin (A1AT), respectively. The cutoff <-1SD for weight-for-length and length-for-age was used to define wasting and stunting. Multivariable linear regression analysis explored if cumulative enteric parasitic infections explained variability of fecal biomarkers, after adjusting for potential confounders. Eighty infants were included. Giardia duodenalis and soil-transmitted helminths (STH) were the most frequent parasites. The median (interquartile range) levels were 2.87 μg/g (2.41-3.92) for S100A12 and 165.1 μg/g (66.0-275.6) for A1AT. Weak evidence of association was found between S100A12 levels and G. duodenalis (p = 0.080) and STH infections (p = 0.089), and between A1AT levels and parasitic infection of any etiology (p = 0.089), at 24-months of age. Significant associations between A1AT levels and wasting (p = 0.006) and stunting (p = 0.044) were found. Previous parasitic infections were not associated with fecal biomarkers at 24 months of age. To summarize, previous asymptomatic parasitic infections showed no association with intestinal barrier dysfunction. Notwithstanding, a tendency toward increased levels of the inflammatory biomarker was observed for current G. duodenalis and STH infections, and increased levels of the permeability biomarker were significantly associated with stunting and wasting.
Background: Sickle cell disease (SCD) has extremely variable phenotypes, and several factors have been associated with the severity of the disease. Objectives: To analyze the chronic complications of SCD and look for predictive risk factors for increased severity and number of complications. Methods: Retrospective study including all children followed for SCD in the Paediatric Haematology Unit of a tertiary hospital in Portugal, who completed 17 yr old between the years 2004 and 2013. Results: We identified 44 patients, 55% female and 98% black. Chronic complications occurred in 80% of cases. Slight dilatation of the left ventricle was the most frequent complication (47.7%), followed by respiratory function disturbs (43.2%), microlithiasis or cholelithiasis (40.9%), increased flow velocity of cerebral arteries (31.8%), enuresis, delayed puberty and bone abnormalities (6.8% each), sickle cell retinopathy and leg ulcer (4.6% each) and recurrent priapism (2.3%). We identified a statistically significant association between leukocytes >15 000/lL and a higher number of hospitalizations (P < 0.001) and chronic complications of the disease (P = 0.035). The occurrence of dactylitis in first year of life was also significantly associated with a higher number of hospitalizations (P = 0.004) and chronic complications (P = 0.018). The presence of a-thalassemia was associated with a lower number of chronic complications (P = 0.036). Conclusions: Leucocytosis and dactylitis in the first year of life can be predictors of SCD severity, while the presence of a-thalassemia can be protective. The determination of early predictors of chronic complications of SCD may improve the comprehensive care of these patients.
Chickenpox should be considered in differential diagnosis of ischaemic stroke in healthy children who fit the clinical and radiological typical profile of PVCA.
Resumo Objetivos: São objetivos deste estudo a validação do Questionário da Medicina Centrada no Paciente em Portugal (MCP-PT), e a verificação da existência de MCP na opinião do consulente, relacionando-a com a Capacitação, segundo instrumento próprio (PEI/ICC). Tipo de Estudo: Observacional, multicêntrico, não aleatorizado. Local: Três Unidades de Saúde Familiar do ACeS Baixo Mondego.Abstract Objectives: To validate the questionnaire of Patient--Centered Medicine in Portugal (PCM-PT), in order to get the patients' opinion about the existence of the PCM, and to co-relate it to the Enablement, according to the PEI/ICC. Design: observational, multicentric, non-randomised.Setting: Three Family Health Units (FHU), ACeS Baixo Mondego. Pontos a reter:O conceito da Medicina Centrada no Paciente (MCP) data da década de 1980 e nos nossos dias começa a ocupar um papel central nos cuidados médicos. A MCP apresenta-se como uma abordagem que abrange a experiência total de doença do paciente, enfatizando a importância de tomar as crenças e características do mesmo em consideração na tomada de decisões clínicas.A sua avaliação deve ser feita pelo lado do consulente pelo que se fez trabalho de desenvolvimento de questionário específico e se verificou a sua fiabilidade confrontando os resultados com a Capacitação.O Questionário MCP-PT para a população portuguesa permite aferir a opinião do consulente sobre a aplicação da MCP durante a consulta com o Médico de Família e verificámos uma correlação positiva entre a MCP e a Capacitação, mesmo que 42,5% da amostra não tivesse em plenitude percebido os seis componentes da MCP.Deste modo, compreendemos que um método clínico centrado no paciente, que privilegia a comunicação, a parceria e a promoção de saúde, tem repercussões positivas no paciente, que se sente mais habilitado e capaz de lidar com a sua vida e as suas doenças.
Introduction: One year ago, Portugal entered its first lockdown because of the coronavirus disease-2019 (COVID-19) pandemic. The impact of this on delays in cancer diagnosis and treatment is a major concern, which may negatively affect the outcomes of these patients. Materials and Methods:This retrospective, single-center analysis compared the clinical and pathological characteristics of breast cancer (BC) patients referred to a medical oncology first appointment between March 2020 and 2021, with the same period in the previous year.Results: Strikingly, there was a 40% reduction in the number of BC patients during lockdown. However, there was a statistically significant increase in the proportion of metastatic BC patients admitted for the first time for systemic therapy (13.6% vs. 28.9%, p = 0.003). Additionally, a statistically significant increase in the number of patients with bilateral early BC at diagnosis after March 2020 was found (7.2% vs. 1.9%, p = 0.043). Conclusion:These findings support international recommendations for an accelerated restoration of BC screening, to reduce incidence of advanced breast cancer at diagnosis and mitigate the expected impact of the COVID-19 pandemic on patients with cancer. Further work is needed to examine in detail the impact of measures to manage the COVID-19 pandemic on breast cancer outcomes.
