Vorapaxar

Antiplatelet drugs are the cornerstone of treatment for patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention. Clopidogrel and aspirin improve long-term vascular clinical outcomes in these patients and have become a standard of care. However, many patients still experience ischemic/thrombotic events, and it appears that insufficient response to both aspirin and clopidogrel contribute to this failure. Newer P2Y12 receptor blocker therapy resulted in only an approximately 2% reduction in absolute risk compared with clopidogrel. This indicates that residual ischemic events are mediated by other pathways that are unblocked by current dual antiplatelet therapy. Thrombin is the most potent platelet agonist (over 1000 times more than adenosine diphosphate on a molar basis). Thrombin-mediated platelet activation depends on proteaseactivated receptor (PAR) binding. PAR-1 is the main receptor for thrombin on human platelets; PAR-4 may contribute to platelet activation at much higher concentrations of thrombin. Inhibition of the PAR-1 may provide additional benefits over the standard dual antiplatelet therapy in attenuating ischemic event in patients with ACS. Vorapaxar is a new highly selective oral PAR-1 antagonist that inhibits thrombin-induced platelet activation. We review the pharmacokinetic, pharmacodynamic and clinical profile of vorapaxar. Although preliminary data indicated that vorapaxar may have the potential to improve ischemic outcomes without significantly increasing bleeding, more recent larger clinical trials seem to be less optimistic about both its effectiveness and safety. At this time, the role of vorapaxar in the settings of atherothrombotic disorders is not clear. Although it may be associated with less bleeding than P2Y12 receptor blockers, its antithrombotic effectiveness and side effects are major concerns

Estudio de caso sobre el desarrollo profesional de una futura docente de Biología según el Modelo Interconectado de Crecimiento Profesional Docente

Este trabajo presenta los primeros resultados de un proyecto que busca analizar los cambios en el CDC sobre Biodiversidad reconocidos por estudiantes del profesorado de Ciencias Biológicas durante la Práctica Docente. Mediante el uso del Modelo Interconectado de Crecimiento Profesional Docente como principal herramienta metodológica se analizaron las manifestaciones escritas de los estudiantes durante el trayecto de la práctica expresadas en registros propios de la asignatura y a los seis meses finalizada la residencia se realizó una entrevista semi-estructurada. Los primeros resultados en una de las estudiantes evidenciaron principalmente cambios percibidos en el conocimiento sobre los aprendizajes de los estudiantes, las estrategias didácticas y la dimensión emocional. Es destacable que en los tres componentes el cambio se evidencia en el dominio personal, modificando a lo largo de toda su residencia sus concepciones, ideas y creencias sobre el ser docente y el enseñar en la escuela.Especialización en Docencia Universitari

Clinical nutrition in internal medicine: An Italian survey by the scientific societies FADOI and SINPE

Objectives: Patients hospitalized in internal medicine are frequently malnourished or at risk for malnutrition. The aim of this study, conducted by the Federation of Associations of Hospital Internists (FADOI) and the Italian Society of Artificial Nutrition and Metabolism (SINPE) was to assess the nutritional management of internal medicine inpatients in Italy, to identify critical issues and formulate practical proposals to improve nutritional treatment.Methods: From February to April 2021, FADOI and SINPE conducted a national web-based survey, including a 13 multiple-choice item questionnaire related to three key areas:screening and assessment of malnutrition and associated/overlapping sarcopenia and dysphagia;specialist consultations; andmanagement of nutritional support.Results: Responding to the questionnaire were 266 physicians among FADOI members (10.76%). Screening for malnutrition is performed with validated tests, within standardized care pathways, or routinely, only by 22% of participants. Global Leadership Initiative on Malnutrition criteria for diagnosis of malnutrition are little used (20%). Screening for sarcopenia was insufficient as the systematic use of assessment tools (handgrip/chair test) was minimal (3%). Screening for dysphagia is not a routine procedure for at-risk patients according to 33% of participants. Systematic involvement of clinical nutrition services/units in the management of malnourished/sarcopenic patients was reported by only 17% of internists.Conclusions: To overcome the critical issues that emerged from the present study, FADOI and SINPE experts proposed practical solutions to promote the application of the most recent guidelines and to improve awareness and sensitivity to nutritional management in internal medicine real-life settings

Clinical Features, Short-Term Mortality, and Prognostic Risk Factors of Septic Patients Admitted to Internal Medicine Units: Results of an Italian Multicenter Prospective Study

Only a few studies provided data on the clinical history of sepsis within internal Medicine units.The aim of the study was to assess the short-term mortality and to evaluate the prognostic risk factors in a large cohort of septic patients treated in internal medicine units.Thirty-one internal medicine units participated to the study. Within each participating unit, all admitted patients were screened for the presence of sepsis.A total of 533 patients were included; 78 patients (14.6%, 95%CI 11.9, 18.0%) died during hospitalization; mortality rate was 5.5% (95% CI 3.1, 9.6%) in patients with nonsevere sepsis and 20.1% (95%CI 16.2, 28.8%) in patients with severe sepsis or septic shock. Severe sepsis or septic shock (OR 4.41, 95%CI 1.93, 10.05), immune system weakening (OR 2.10, 95%CI 1.12, 3.94), active solid cancer (OR 2.14, 95% CI 1.16, 3.94), and age (OR 1.03 per year, 95% CI 1.01, 1.06) were significantly associated with an increased mortality risk, whereas blood culture positive for Escherichia coli was significantly associated with a reduced mortality risk (OR 0.46, 95%CI 0.24, 0.88).In-hospital mortality of septic patients treated in internal medicine units appeared similar to the mortality rate obtained in recent studies conducted in the ICU setting

Complexity in hospital internal medicine departments: What are we talking about?

Internal medicine (IM) patients are mostly elderly, with multiple complex co-morbidities, usually chronic. The complexity of these patients involves the intricate entanglement of two or more systems (e.g. body and disease, family-socio-economic and environmental status, coordination of care and therapies) and this requires comprehensive, multi-dimensional assessment (MDA). Despite attempts to improve management of chronic conditions, and the availability of several MDA tools, defining the complex patient is still problematic. The complex profile of our patients can only be described through the best assessment tools designed to identify their characteristics. In order to do this, the Federation of Associations of Hospital Doctors on Internal Medicine FADOI has created its own vision of IM. This involves understanding the different needs of the patient, and analyzing diseases clusters and the possible relationships between them. By exploring the real complexity of our patients and selecting their real needs, we can exercise holistic, anthropological and appropriate choices for their treatment and care. A simpler assessment approach must be adopted for our complex patients, and alternative tools should be used to improve clinical evaluation and prognostic stratification in a hierarchical selection of priorities. Further investigation of complex patients admitted to IM wards is needed

Kinetics of cytomegalovirus and Epstein-Barr virus DNA in whole blood and plasma of kidney transplant recipients: Implications on management strategies

This retrospective multicenter cohort study investigated the kinetics (ascending and descending phases) of cytomegalovirus (CMV) and Epstein-Barr virus (EBV)-DNA in whole blood (WB) and plasma samples collected from adult kidney transplant (KT) recipients. CMV-DNA kinetics according to antiviral therapy were investigated. Three hundred twenty-eight paired samples from 42 episodes of CMV infection and 157 paired samples from 26 episodes of EBV infection were analyzed by a single commercial molecular method approved by regulatory agencies for both matrices. CMV-DNAemia followed different kinetics in WB and plasma. In the descending phase of infection, a slower decay of viral load and a higher percentage of CMV-DNA positive samples were observed in plasma versus WB. In the 72.4% of patients receiving antiviral therapy, monitoring with plasma CMV-DNAemia versus WB CMV-DNAemia could delay treatment interruption by 7-14 days. Discontinuation of therapy based on WB monitoring did not result in relapsed infection in any patients. Highly different EBV-DNA kinetics in WB and plasma were observed due to lower positivity in plasma; EBV positive samples with a quantitative result in both blood compartments were observed in only 11.5% of cases. Our results emphasize the potential role of WB as specimen type for post-KT surveillance of both infections for disease prevention and management

Clinical characteristics of very old patients hospitalized in internal medicine wards for heart failure: a sub-analysis of the FADOI-CONFINE Study Group

The incidence and prevalence of chronic heart failure are increasing worldwide, as is the number of very old patients (>85 years) affected by this disease. The aim of this sub-analysis of the multicenter, observational CONFINE study was to detect clinical and therapeutic peculiarities in patients with chronic heart failure aged >85 years. We recruited patients admitted with a diagnosis of chronic heart failure and present in the hospital in five index days, in 91 Units of Internal Medicine. The patients' clinical characteristics, functional and cognitive status, and the management of the heart failure were analyzed. A total of 1444 subjects were evaluated, of whom 329 (23.1%) were over 85 years old. Signs and symptoms of chronic heart failure were more common in very old patients, as were severe renal insufficiency, anemia, disability and cognitive impairment. The present survey found important age-related differences (concomitant diseases, cognitive status) among patients with chronic heart failure, as well as different therapeutic strategies and clinical outcome for patients over 85 years old. Since these patients are usually excluded from clinical trials and their management remains empirical, specific studies focused on the treatment of very old patients with chronic heart failure are needed

Complexity of patients with chronic obstructive pulmonary disease hospitalized in internal medicine: a survey by FADOI

Chronic obstructive pulmonary disease (COPD) is one of the most frequent pathologies among patients hospitalized in Internal Medicine (IM) Departments. COPD is frequently associated with concomitant diseases, which represent major causes of death, and affect disease management. Objectives of our study are to assess the prevalence of COPD patients in IM, to evaluate their comorbidity status, and to describe their complexity, by means of the validated multidimensional prognostic index (MPI) score. COMPLEXICO is an observational, prospective, multicenter study, enrolling consecutive patients hospitalized for any cause in IM, with diagnosis of COPD documented by spirometry. A total of 1002 patients in 43 IM Units in Italy were enrolled. The prevalence of COPD in IM was found to be 18.1%, and 72.8% of patients had at least three chronic diseases other than COPD. The mean MPI was 0.43±0.15, and according to a stratification algorithm 31.8% of patients were classified as having low-risk, 58.9% moderate-risk and 9.3% severe-risk of adverse outcome. More than two-thirds of COPD patients in our study present moderate to severe risk of poor outcome according to the MPI stratification

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.
