Down syndrome is a frequent clinical entity, being considered one of the most frequent chromosomal aberrations. It is characterised by a typical clinical phenotype and is associated with a heterogeneous group of organ and system-specific abnormalities. The cardiovascular system is commonly affected and if so, it may be associated with an increased morbidity and mortality. Cerebrovascular events in patients with Down syndrome are multifactorial, being possibly related to congenital heart disease, vascular malformations and traditional cardiovascular risk factors...

BACKGROUND: Community health workers are community members who provide education and care for patients for a broad range of health issues, including diabetes mellitus. However, few community health workers are trained for diabetes education and little is known about the effectiveness of their interventions. The aim of this study is to evaluate the effect of a diabetes education program delivered to community health workers in improving the metabolic control of patients with type 2 diabetes mellitus...

OBJECTIVES: Hospital-based health technology assessment (HTA) has become increasingly important in Brazil due to its strategic importance to promote adoption, incorporation, dissemination, and disinvestment of technologies. A strategy to foster hospital-based HTA was implemented in 2009 by creating hospital-based HTA nuclei (NATS) at university hospitals and other strategic hospitals. METHODS: Between 2011 and 2012, we interviewed board members in twenty-three NATS located in all geographic regions of Brazil to assess their general characteristics, scientific output, and challenges...

Lagochilascariasis is a parasitic disease caused by a helminth of the order Ascaroidea, genus Lagochilascaris that comprises 6 species, among which only Lagochilascaris minor Leiper, 1909, is implicated in the human form of the disease. It is remarkable that the majority of cases of human lagochilascariasis in the Americas have been reported in Brazil. The natural definitive hosts of this parasite seem to be wild felines and canines. Lagochilascariasis is mostly a chronic human disease that can persist for several years, in which the parasite burrows into the subcutaneous tissues of the neck, paranasal sinuses, and mastoid...

Objective: The purpose of this study was to investigate the association between three helping behaviors and incident cardiovascular disease (CVD; heart attack, stroke; fatal and nonfatal), with an exploration of gender differences. The study is framed within the caregiving system model. Helping others is argued to be an evolved characteristic of humans that yields beneficial health effects. Methods: Data were taken from the 2004-2014 waves of the Health and Retirement Study...

Development of multicellular organisms is driven by a series of mitotic divisions after fertilization. Total cytoplasmic volume does not increase during this process, resulting in an increasing number of smaller daughter cells. Cell divisions are initially synchronous in an early embryo, but this ends at the 16-cell stage in the sea urchin. Orchesterated mitosis does, however, continue in subpopulations via the coordination of two different processes: karyokinesis and cytokinesis. Part of this asynchrony is due to the differentiation of lineages...

Low cost and high efficiency cellulolytic cocktails can consolidate lignocellulosic ethanol technologies. Sugarcane bagasse (SCB) is a low cost agro-industrial residue, and its use as a carbon source can reduce the costs of fungi cultivation for enzyme production. Chrysoporthe cubensis grown under solid state fermentation (SSF) with wheat bran has potential to produce efficient enzymatic extracts for SCB saccharification. This fungus was grown under submersed fermentation (SmF) and SSF with in natura SCB, pretreated with acid or alkali and with others carbon sources...

A healthy 31-year-old woman presented with a 20-year history of asymptomatic skin-colored papules and nodules on the central area of the face. Her maternal grandmother, aunts, mother, and sister also had similar lesions. Clinical, histopathological, and genetic features allowed the diagnosis of multiple familial trichoepithelioma. The patient and family were referred to the genetic department for genetic counselling. Close follow-up for the possibility of secondary basal cell carcinoma is warranted.

BACKGROUND: Though normally linked to bone and cartilage development, the Runt-related transcription factor, RUNX2, was reported in the mouse heart during development of the valves. We examined RUNX2 expression and function in the developing avian heart as it related to the epithelial-mesenchymal transition (EMT) in the atrioventricular canal. EMT can be separated into an activation stage involving hypertrophy and cell separation and an invasion stage where cells invade the extracellular matrix...

Although infliximab (IFX) is an efficient therapy for ulcerative colitis (UC) patients, a considerably high rate of therapeutic failures still occurs. This study aimed at a better understanding of IFX pharmacokinetics and pharmacodynamics among clinically-asymptomatic UC patients. This was a multicentric and prospective study involving 65 UC patients in the maintenance phase of IFX therapy. There were no significant differences between patients with positive and negative clinical, endoscopic and histological outcomes concerning their IFX trough levels (TLs), area under the IFX concentration vs...

This work describes a novel approach to produce an antibody-like biomimetic material. It includes preparing composite imprinted material never presented before, with highly conductive support nanostructures and assembling a high conductivity polymeric layer at low temperature. Overall, such highly conductive material may enhance the final features of electrically-based devices. Acetylcholine (ACh) was selected as target analyte, a neurotransmitter of importance in Alzheimer's disease. Potentiometric transduction was preferred, allowing quick responses and future adaptation to point-of-care requirements...

We have previously demonstrated that maternal exposure to glyphosate-based herbicide (GBH) leads to glutamate excitotoxicity in 15-day-old rat hippocampus. The present study was conducted in order to investigate the effects of subchronic exposure to GBH on some neurochemical and behavioral parameters in immature and adult offspring. Rats were exposed to 1% GBH in drinking water (corresponding to 0.36% of glyphosate) from gestational day 5 until postnatal day (PND)-15 or PND60. Results showed that GBH exposure during both prenatal and postnatal periods causes oxidative stress, affects cholinergic and glutamatergic neurotransmission in offspring hippocampus from immature and adult rats...

João Ribeiro Pinto, João Manuel Rs Tavares
This article presents the design and evaluation of an algorithm for urinary bladder segmentation in medical images, from contrastless computed tomography studies of patients suffering from bladder wall tumours. These situations require versatile methods of segmentation, able to adapt to the structural changes the tumours provoke in the bladder wall, reflected as irregularities on the images obtained, creating adversities to the segmentation process. This semi-automatic method uses fuzzy c-means clustering, a Gaussian-curve-based intensity transformation, and active contour models, requiring only the physician's input of a single seed point for each anatomical view, in order to segment the bladder volume in all frames that include it...

Image assessment of the arterial system plays an important role in the diagnosis of cardiovascular diseases. The segmentation of the lumen and media-adventitia in intravascular (IVUS) images of the coronary artery is the first step towards the evaluation of the morphology of the vessel under analysis and the identification of possible atherosclerotic lesions. In this study, a fully automatic method for the segmentation of the lumen in IVUS images of the coronary artery is presented. The proposed method relies on the K-means algorithm and the mean roundness to identify the region corresponding to the potential lumen...

Dissemination of carbapenem-resistant Acinetobacter baumannii (CRAB) is mainly due to the spread of clonal lineages, particularly those included into the clonal complexes (CC) CC1, CC2, CC15, CC25, and CC79. We evaluated the usefulness of a recently modified PCR-based trilocus sequence-based typing (m3LST) in comparison with the standard multilocus sequence typing (MSLT) of 7 housekeeping genes as per the Institute Pasteur Scheme to assign the clonal complexes in CRAB. A collection of 78 CRAB isolated from 67 different Brazilian health institutions was submitted to both methodologies, and concordance rate was calculated...

Copaiba oleoresins are used in alternative medicine as anti-inflammatory, antitumoral, and antimicrobial treatments. (-)-Copalic acid (CA) is the major diterpene found in exudates from Copaifera species. We have examined the genotoxicity and the chemopreventive potential of Copaifera multijuga oleoresin (CM) and CA. Genotoxicity assessment was examined with the peripheral blood micronucleus test and the comet assay (male Swiss mouse hepatocytes). In the chemoprevention study, we evaluated the effects of CM and CA on the formation of 1,2-dimethylhydrazine (DMH)-induced aberrant crypt foci (ACF) in male Wistar rat colon...

It is estimated that in 2025, Brazil will have the sixth largest elderly population in the world. Beyond the economic consequences of this projection, this changing demographic portends significant changes in the social realm. The aim of this study was to review and consider a range of government documents directed towards elderly Brazilian citizens that have been developed over the past thirty years to explore the ways that caregivers of older persons are positioned in daily care practices through the discourses such documents deploy...

Central diabetes insipidus (DI) is a rare clinical entity characterized by low circulating levels of antidiuretic hormone (ADH) presenting with polyuria and volume depletion. Pituitary surgery is the most common cause of central DI in adults. Pituitary and hypothalamic disease, particularly invasive neoplasms, rarely cause DI, being idiopathic cases responsible for the majority of non-surgical cases. HIV patients, especially those with poor virulogical control, are prone to the development of CNS neoplasms, particularly lymphomas...
