Rheumatic heart disease predisposing to embolic myocardial infarction: a multimodality imaging approach

We report a clinical case of a 45-year-old male with a diagnosis of inferior myocardial infarction and previous history of rheumatic fever during his childhood. Coronary angiography demonstrated normal coronary arteries. Transthoracic echocardiogram showed hypokinetic left ventricular inferolateral wall and mitral stenosis; furthermore, speckle tracking analysis revealed reduction of global longitudinal strain involving the inferior wall. A three-dimensional transesophaegeal echocardiography, performed to better characterize the anatomy of the valve and to find possible source of embolic infarct in an enlarged left atrium, showed rheumatic valvular involvement. Cardiac magnetic resonance confirmed the ischemic damage and also provided prognostic information. A multimodality imaging approach should be mandatory in patients with acute myocardial infarction and normal coronary angiography, to define possible sources of embolic infarction and to quantify myocardial damage

Between quantity and quality: competing views on the role of Big Data for causal inference

When does more data help and when does it not in the sciences? In the past decade, this question has become central because of the phenomenon of Big Data. While these discussions started as a result of somewhat naive ideas that have been closely analyzed and mostly rejected in the philosophy of data, the question about the epistemic difference that more or less data make still matters, especially in light of the impressive performance of data science tools, which seem to improve their performance the more data are trained on. In several areas of the sciences, having more data is connected to methodological and epistemic benefits and something that research should strive towards. More data is often equated to better science: this elicits crucial questions about the epistemic value of the quantity of data. In this chapter, we discuss this problem in light of current discussions in the life and health sciences and the philosophy of data

The Red Blood Cell as a Gender-Associated Biomarker in Metabolic Syndrome: A Pilot Study

In the present pilot study (56 patients), some red blood cell parameters in samples from patients with metabolic syndrome and subclinical atherosclerosis, but without any sign of coronary artery disease, have been analyzed. The main goal of this work was to determine, in this preclinical state, new peripheral gender-associated bioindicators of possible diagnostic or prognostic value. In particular, three different “indicators” of red blood cell injury and aging have been evaluated: glycophorin A, CD47, and phosphatidylserine externalization. Interestingly, all these determinants appeared significantly modified and displayed gender differences. These findings could provide novel and useful hints in the research for gender-based real-time bioindicators in the progression of metabolic syndrome towards coronary artery disease. Further, more extensive studies are, however, necessary in order to validate these findings

Comparison between balloon angioplasty and additional coronary stent implantation for the treatment of drug-eluting stent restenosis: 18-month clinical outcomes

OBJECTIVE: To evaluate the long-term outcomes after different modalities of treatment of drug-eluting stent (DES) in-stent restenosis (ISR) in a 'real world' setting. METHODS: Actually, few and conflicting data are available about the management of in-stent restenosis (ISR) after DES implantation. In our 'real world' registry 1082 consecutive patients who received a DES implantation were included. At 9-month angiographic follow-up, 93 patients presented a DES ISR that was treated with 'homo-DES' (HMD) (N = 27), 'hetero-DES' (HTD) (N = 19) and conventional balloon angioplasty (POBA) (N = 47). We evaluated the clinical outcomes in terms of major adverse cardiac event (MACE) (death, myocardial infarction and target vessel revascularization) at 18 months. RESULTS: There was no difference for clinical and angiographic characteristics between the three groups, except for the presence of silent ischaemia as clinical presentation (7.7 HMD vs. 2.2% POBA; P = 0.0001). No late stent thrombosis was found. At 18-month clinical follow-up patients treated with HMD, HTD and POBA presented a rate of MACE of 10.2, 0 and 8.7%, respectively (P = NS). Kaplan-Meier survival probability showed that HTD and POBA treatment tended to have more favourable outcomes at 18 months than the HMD treatment. CONCLUSION: In our registry, POBA seems to be as effective as other DES implantations in cases of DES ISR, especially in cases of focal type (Mehran classification IA, IC), in terms of long-term outcomes

Open data, Science and Society: launching Oasis, the flagship initiative of the Istituto Italiano di Antropologia

The Open Data philosophy has gained considerable momentum in recent years, both in society and the scientific community. The accessibility via web of open data from the public sector has remarkably increased in the last decade, although there are substantial differences among nations (http://datacatalogs.org/). The expectation of many citizens, organizations and pressure groups (the so called “open government” movement) is that the free release of data from public administrations may help increase government transparency and accountability

Diagnosis, treatment and prevention of pediatric obesity: consensus position statement of the Italian Society for Pediatric Endocrinology and Diabetology and the Italian Society of Pediatrics

The Italian Consensus Position Statement on Diagnosis, Treatment and Prevention of Obesity in Children and Adolescents integrates and updates the previous guidelines to deliver an evidence based approach to the disease. The following areas were reviewed: (1) obesity definition and causes of secondary obesity; (2) physical and psychosocial comorbidities; (3) treatment and care settings; (4) prevention.The main novelties deriving from the Italian experience lie in the definition, screening of the cardiometabolic and hepatic risk factors and the endorsement of a staged approach to treatment. The evidence based efficacy of behavioral intervention versus pharmacological or surgical treatments is reported. Lastly, the prevention by promoting healthful diet, physical activity, sleep pattern, and environment is strongly recommended since the intrauterine phase

Transferência do conhecimento de trabalhadores em processo de aposentadoria em uma instituição de ensino superior

Resumo Buscou-se, neste trabalho, compreender a importância e a contribuição da transferência do conhecimento (TC) de trabalhadores em processo de aposentadoria em uma instituição de ensino superior (IES). Tal pesquisa se justifica em razão de a TC, no contexto da aposentadoria, ser abordada por diferentes áreas, porém, ter pouca ênfase nas ciências administrativas. Realizou-se um estudo de caso qualitativo, embasado no marco teórico da criação e na TC, do qual participaram trabalhadores em processo de aposentadoria, gestores e trabalhadores jovens. Foram realizados entrevistas semiestruturadas e grupos focais, com a participação de 32 pessoas, bem como observação não participante com cerca de 260 trabalhadores. Os dados foram organizados com o apoio do software NVivo®11, triangulados e analisados por meio da análise de conteúdo. Afirma-se que a TC traz contribuições para os trabalhadores no sentido de melhorar as relações de trabalho e aproximar as pessoas, promover maior grau de autonomia e reconhecimento, perceber oportunidades de crescimento profissional e pessoal, bem como contribuir para a IES, uma vez que o histórico institucional é valorizado, processos são aprimorados, custos organizacionais são reduzidos e o clima organizacional é otimizado. Assim, concluímos que os diferentes conhecimentos são importantes para a IES, bem como para as pessoas que dela fazem parte, e ressaltamos a necessidade da implementação de ações para que o conhecimento não seja perdido quando o trabalhador se afastar do trabalho
