Lyme Borreliosis as a Cause of Myocarditis in Pediatric Age

Lyme borreliosis with myocarditis is rare in pediatrics and diagnosis requires a high index of suspicion. We present an adolescent with myocarditis, depressed left ventricular function, and evidence of Lyme borreliosis infection. Early recognition and treatment of Lyme disease can help to avoid serious complications.info:eu-repo/semantics/publishedVersio

Non-alcoholic fatty liver disease (NAFLD) as a neglected metabolic companion of psychiatric disorders: common pathways and future approaches

Background: Non-alcoholic fatty liver disease (NAFLD) is characterized by hepatic steatosis in over 5% of the parenchyma in the absence of excessive alcohol consumption. It is more prevalent in patients with diverse mental disorders, being part of the comorbidity driving loss of life expectancy and quality of life, yet remains a neglected entity. NAFLD can progress to non-alcoholic steatohepatitis (NASH) and increases the risk for cirrhosis and hepatic carcinoma. Both NAFLD and mental disorders share pathophysiological pathways, and also present a complex, bidirectional relationship with the metabolic syndrome (MetS) and related cardiometabolic diseases. Main text: This review compares the demographic data on NAFLD and NASH among the global population and the psychiatric population, finding differences that suggest a higher incidence of this disease among the latter. It also analyzes the link between NAFLD and psychiatric disorders, looking into common pathophysiological pathways, such as metabolic, genetic, and lifestyle factors. Finally, possible treatments, tailored approaches, and future research directions are suggested. Conclusion: NAFLD is part of a complex system of mental and non-communicable somatic disorders with a common pathogenesis, based on shared lifestyle and environmental risks, mediated by dysregulation of inflammation, oxidative stress pathways, and mitochondrial function. The recognition of the prevalent comorbidity between NAFLD and mental disorders is required to inform clinical practice and develop novel interventions to prevent and treat these complex and interacting disorders

Trends and challenges in the Portuguese penitentiary system: from law to practice

This article focuses on the trends and challenges faced by the Portuguese penitentiary system between 2000 and 2017, taking into account the Portuguese Penal Law, penal statistics, national and international reports, and studies regarding the Portuguese prison system. The description of the changes in the Penal Law helps us to understand, on one hand, the changes in penal statistics over time and, on the other hand, the inconsistencies between the law in books and law in practice

População no sistema prisional português: evolução e tendências entre 2000 e 2017

Este artigo apresenta uma reflexão sobre as principais tendências identificadas na evolução da população recenseada no sistema prisional português, entre 2000 e 2017. Partindo de uma análise que cruza as alterações no campo do direito penal com os dados estatísticos oficiais e relatórios e estudos nacionais e internacionais sobre a aplicação da pena de prisão no país, pretende-se compreender e identificar alguns dos desafios colocados ao sistema pelo movimento da população prisional, assim como pelas mudanças registadas no perfil desta população. A evolução e tendências identificadas permitem indagar sobre o impacto da lei e contribuir para identificar alguns dos caminhos que falta traçar em resposta aos imperativos legais internacionais em matéria da população a cumprir pena privativa de liberdade

Endometrial Cancer Spheres Show Cancer Stem Cells Phenotype and Preference for Oxidative Metabolism

This study aimed to characterize endometrial cancer regarding cancer stem cells (CSC) markers, regulatory and differentiation pathways, tumorigenicity and glucose metabolism. Endometrial cancer cell line ECC1 was submitted to sphere forming protocols. The first spheres generation (ES1) was cultured in adherent conditions (G1). This procedure was repeated and was obtained generations of spheres (ES1, ES2 and ES3) and spheres-derived cells in adherent conditions (G1, G2 and G3). Populations were characterized regarding CD133, CD24, CD44, aldehyde dehydrogenase (ALDH), hormonal receptors, HER2, P53 and β-catenin, fluorine-18 fluorodeoxyglucose ([18F]FDG) uptake and metabolism by NMR spectroscopy. An heterotopic model evaluated differential tumor growth. The spheres self-renewal was higher in ES3. The putative CSC markers CD133, CD44 and ALDH expression were higher in spheres. The expression of estrogen receptor (ER)α and P53 decreased in spheres, ERβ and progesterone receptor had no significant changes and β-catenin showed a tendency to increase. There was a higher 18F-FDG uptake in spheres, which also showed a lower lactate production and an oxidative cytosol status. The tumorigenesis in vivo showed an earlier growth of tumours derived from ES3. Endometrial spheres presented self-renewal and differentiation capacity, expressed CSC markers and an undifferentiated phenotype, showing preference for oxidative metabolism.info:eu-repo/semantics/publishedVersio

Helminth infections and gut microbiota - a feline perspective

$\textbf{BACKGROUND}$: Investigations of the relationships between the gut microbiota and gastrointestinal parasitic nematodes are attracting growing interest by the scientific community, driven by the need to better understand the contribution of parasite-associated changes in the composition of the gut flora to both host malnutrition and immune modulation. These studies have however been carried out mainly in humans and experimental animals, while knowledge of the make-up of the gut commensal flora in presence or absence of infection by parasitic nematodes in domestic animals is limited. In this study, we investigate the qualitative and quantitative impact that infections by a widespread parasite of cats (i.e. $\textit{Toxocara cati}$) exert on the gut microbiota of feline hosts. $\textbf{METHODS}$: The faecal microbiota of cats with patent infection by $\textit{T. cati}$ (= $\textit{Tc+}$), as well as that of negative controls (= $\textit{Tc-}$) was examined via high-throughput sequencing of the V3-V4 hypervariable region of the bacterial 16S rRNA gene, followed by bioinformatics and biostatistical analyses of sequence data. $\textbf{RESULTS}$: A total of 2,325,366 useable high-quality sequences were generated from the faecal samples analysed in this study and subjected to further bioinformatics analyses, which led to the identification of 128 OTUs and nine bacterial phyla, respectively. The phylum Firmicutes was predominant in all samples analysed (mean of 53.0%), followed by the phyla Proteobacteria (13.8%), Actinobacteria (13.7%) and Bacteroidetes (10.1%). Among others, bacteria of the order Lactobacillales, the family $\textit{Enterococcaceae}$ and genera $\textit{Enterococcus}$ and $\textit{Dorea}$ showed a trend towards increased abundance in $\textit{Tc+}$ compared with $\textit{Tc-}$ samples, while no significant differences in OTU richness and diversity were recorded between $\textit{Tc+}$ and $\textit{Tc-}$ samples ($\textit{P}$=0.485 and $\textit{P}$=0.581, respectively). However, Canonical Correlation and Redundancy Analyses were able to separate samples by infection status ($\textit{P}$=0.030 and $\textit{P}$=0.015, respectively), which suggests a correlation between the latter and the composition of the feline faecal microbiota. $\textbf{CONCLUSIONS}$: In spite of the relatively small number of samples analysed, subtle differences in the composition of the gut microbiota of $\textit{Tc+}$ vs $\textit{Tc-}$ cats could be identified, some of which in accordance with current data from humans and laboratory animal hosts. Nevertheless, the findings from this study contribute valuable knowledge to the yet little explored area of parasite-microbiota interactions in domestic animals.This work was supported by Merial Pty Ltd (CC, AG, DO) and ESCCAP UK & Ireland (CC).
