Cardiovascular magnetic resonance characterization of a hamartoma in an asyntomatic child

2009

Abstract Background The prevalence of primary cardiac neoplasms is approximately 0.3% and these masses should be distinguished from many of other primary and secondary processes that can occur in the heart. Further assessment of the left ventricular mass presents important clinical implications. Cardiovascular magnetic resonance was used. Clinical case An asyntomatic 12-year-old child was referred for cardiovascular magnetic resonance imaging to further assess a left ventricular mass found after an echocardiography, executed for assessment for sport activity. His past medical history was absolutely negative. The patient was in optimal state of health. The EKG showed an aspecific ST elevatio…

Microsatellite Instability in Colorectal Cancer: Time to Stop Hiding!

2011

Colorectal cancer (CRC) is the second cause of cancer-related death worldwide. Surgery constitutes the primary therapy for these tumors, together with chemotherapy that is usually recommended in patients with metastatic primary CRC. Although molecularly distinct entities arising from different physiopathogenic mechanisms - microsatellite (MSI) and chromosomal instability (also called microsatellite stable, MSS) - have been characterized in CRC, there is still no specific therapeutic approach that takes into account disease’s molecular heterogeneity [1]. MSI is observed in 1015% of sporadic CRCs. MSI CRCs displayed particular morphologic features, with greater predilection for the right colo…

Gingival calcifying epithelial odontogenic tumor: case report and review of the literature comprising a period of 44 years

2011

Calcifying epithelial odontogenic tumors are rare odontogenic neoplasms that account for approximately 1% of all odontogenic tumors. The extraosseous variant is extremely rare, with only few cases being described in the literature. To our knowledge, only 22 cases have been reported over a period of 44 years. Therefore, the aim of this study was to present a critical literature review comprising the period from 1966 to 2010. In addition, we discuss the clinical presentation, diagnosis, and subsequent treatment of a patient with a gingival calcifying epithelial odontogenic tumor in the anterior mandible. This study shows that even though being an extremely rare neoplasm the gingival calcifyin…

Half-width plots, a simple tool to predict peak shape, reveal column kinetics and characterise chromatographic columns in liquid chromatography: Stat…

2013

Peak profiles in chromatography are characterised by their height, position, width and asymmetry; the two latter depend on the values of the left and right peak half-widths. Simple correlations have been found between the peak half-widths and the retention times. The representation of such correlations has been called half-width plots. For isocratic elution, the plots are parabolic, although often, the parabolas can be approximated to straight-lines. The plots can be obtained with the half-widths/retention time data for a set of solutes experiencing the same kinetics, eluted with a mobile phase at fixed or varying composition. When the analysed solutes experience different resistance to mas…

Pedagogical Practices for Virtual Worlds

2010

As a result from activities carried out within Module 2 of the MUVEnation programme about exploring active learning approaches, we have created a collection of practices for teaching and learning in Virtual Worlds, organised in 21 chapters, classified in the following categories of instructional methods: Presentation, Demonstration, Discussion, Drill-and-practice, Tutorial, Cooperative Learning, Gaming, Simulation and Discovery. The educational professionals who participated in the course worked in teams, but in some cases individually to map and describe the existing range of teaching practices in Second Life, and to draw a reflection about the elements for their success. Practices describ…

Global, regional, national, and selected subnational levels of stillbirths, neonatal, infant, and under-5 mortality, 1980-2015 : a systematic analysi…

2016

BACKGROUND: Established in 2000, Millennium Development Goal 4 (MDG4) catalysed extraordinary political, financial, and social commitments to reduce under-5 mortality by two-thirds between 1990 and 2015. At the country level, the pace of progress in improving child survival has varied markedly, highlighting a crucial need to further examine potential drivers of accelerated or slowed decreases in child mortality. The Global Burden of Disease 2015 Study (GBD 2015) provides an analytical framework to comprehensively assess these trends for under-5 mortality, age-specific and cause-specific mortality among children under 5 years, and stillbirths by geography over time. METHODS: Drawing from ana…

Outcomes of Diabetic Retinopathy Post-Bariatric Surgery in Patients with Type 2 Diabetes Mellitus

2021

Bariatric surgery is an emerging therapeutic approach for obese type 2 diabetes mellitus (T2DM) patients, with proven benefits for achieving target glucose control and even remission of diabetes. However, the effect of bariatric surgery upon diabetic retinopathy is still a subject of debate as some studies show a positive effect while others raise concerns about potential early worsening effects. We performed a systematic review, on PubMed, Science Direct, and Web of Science databases regarding the onset and progression of diabetic retinopathy in obese T2DM patients who underwent weight-loss surgical procedures. A total of 6375 T2DM patients were analyzed. Most cases remained stable after b…

Clima motivacional, metas de logro de aproximación y evitación y bienestar en futbolistas cadetes

2021

Basado en la teoría de las metas de logro (modelo dicotómico, Nicholls, 1989; y modelo 2 x 2, Elliot y McGregor, 2001), se exploró un modelo en el que se analizaban las relaciones hipotetizadas entre el clima motivacional percibido, la competencia percibida, las metas de maestría y resultado (aproximación y evitación), e indicadores positivos de bienestar (satisfacción con la vida y autoestima). Participaron 370 jóvenes varones jugadores de fútbol entre los 12 y los 16 años (M = 14,77). Los resultados mostraron una asociación positiva entre la percepción de un clima de implicación en la tarea y las orientaciones a la maestría (aproximación y evitación), y entre la percepción de un clima de …

Gender Confirmation Surgery: Guiding Principles

2016

Abstract Background At this time, no formal training or educational programs exist for surgeons or surgery residents interested in performing gender confirmation surgeries. Aim To propose guiding principles designed to aid with the development of formal surgical training programs focused on gender confirmation surgery. Methods We use expert opinion to provide a “first of its kind” framework for training surgeons to care for transgender and gender nonconforming individuals. Outcomes We describe a multidisciplinary treatment model that describes an educational philosophy and the institution of quality parameters. Results This article represents the first step in the development of a structure…
