Epigenetic regulation of transcription factor binding motifs promotes Th1 response in Chagas disease cardiomyopathy.

Chagas disease, caused by the protozoan , is an endemic parasitic disease of Latin America, affecting 7 million people. Although most patients are asymptomatic, 30% develop complications, including the often-fatal Chronic Chagasic Cardiomyopathy (CCC). Although previous studies have demonstrated some genetic deregulations associated with CCCs, the causes of their deregulations remain poorly described.

Impairment of Multiple Mitochondrial Energy Metabolism Pathways in the Heart of Chagas Disease Cardiomyopathy Patients.

Chagas disease cardiomyopathy (CCC) is an inflammatory dilated cardiomyopathy occurring in 30% of the 6 million infected with the protozoan in Latin America. Survival is significantly lower in CCC than ischemic (IC) and idiopathic dilated cardiomyopathy (DCM). Previous studies disclosed a selective decrease in mitochondrial ATP synthase alpha expression and creatine kinase activity in CCC myocardium as compared to IDC and IC, as well as decreased myocardial ATP production.

Intra-abdominal infections: the role of different classifications on the selection of the best antibiotic treatment.

Background: Intra-abdominal infections (IAIs) represent a most frequent gastrointestinal emergency and serious cause of morbimortality. A full classification, including all facets of IAIs, does not exist. Two classifications are used to subdivide IAIs: uncomplicated or complicated, considering infection extent; and community-acquired, healthcare-associated or hospital-acquired, regarding the place of acquisition.

Long Pentraxin 3-Mediated Fibroblast Growth Factor Trapping Impairs Fibrosarcoma Growth.

Fibrosarcomas are soft tissue mesenchymal tumors originating from transformed fibroblasts. Fibroblast growth factor-2 (FGF2) and its tyrosine-kinase receptors (FGFRs) play pivotal roles in fibrosarcoma onset and progression, FGF2 being actively produced by fibroblasts in all stages along their malignant transformation to the fibrosarcoma stage. The soluble pattern recognition receptor long pentraxin-3 (PTX3) is an extrinsic oncosuppressor whose expression is reduced in different tumor types, including soft tissue sarcomas, via hypermethylation of its gene promoter.

Quality Indicators in Ambulatory Surgery: A Literature Review Comparing Portuguese and International Systems.

Introduction: According to several studies conducted in North America and Europe, ambulatory surgery is a practice that has grown over the years, and both the number of more complex surgical procedures deemed suitable for ambulatory surgery and the number of patients with different co-morbidities which are now suitable for this type of procedure have been increasing. In order to respond to the increased number of day surgeries, as well as to avoid a potential proportional increase in perioperative morbidity, quality control systems must be adopted to enable continuous improvement and minimise predicted risks. The purpose of this study is to review global quality indicators used in ambulatory surgery and compare them with those used in Portugal.

Contrast echocardiography in segmental analysis and intraventricular gradient quantification in hypertrophic cardiomyopathy.

Introduction: Hypertrophic cardiomyopathy (HCM) is a hereditary disorder characterized by ventricular hypertrophy, diastolic dysfunction and hyperdynamic left ventricular systolic function. This excessive contraction is sometimes associated with significant intraventricular pressure gradients. These gradients are dynamic and therefore vary at different times.
