Esposizione all’amianto e responsabilità penale del datore di lavoro: l’accertamento del nesso di causalità
No full textIl lavoro si propone di analizzare il tema della responsabilità del datore di lavoro per patologie contratte dai lavoratori a causa dell’esposizione all’amianto. Il profilo indagato è soprattutto quello dell’individuazione del paradigma ascrittivo da utilizzare in sede di accertamento del nesso eziologico. La diversificazione delle patologie asbesto-correlate, unite all’incertezza in ordine alla stessa patogenesi, rende l’attività di accertamento del giudice assai complessa, anche utilizzando i parametri della “probabilità statistica” e probabilità logica”, che costituiscano attualmente la base dello statuto della causalità in materia penale. Un tale incertezza potrebbe rendere incline il giudice all’utilizzazione di generalizzazioni epidemiologiche, della cui efficacia euristica si dubita tuttavia fortemente in sede scientifica, così come in sede di imputazione dei reati
Amlodipine and celecoxib for treatment of hypertension and osteoarthritis pain
No full textIntroduction: Osteoarthritis constitutes one of the leading causes of pain and disability worldwide with a significant impact on health-care costs. Patients with osteoarthritis are often affected by a number of cardiovascular comorbidities, including hypertension, which is present in about 40% of cases. Just recently, a single tablet combination of amlodipine besylate, a calcium channel blocker, and celecoxib, a nonsteroidal anti-inflammatory drug, indicated for patients for whom treatment with amlodipine for hypertension and celecoxib for osteoarthritis are appropriate, has been recently approved. Areas covered: We reviewed data from clinical studies that investigated safety and efficacy of the combination of amlodipine and celecoxib in hypertensive patients with osteoarthritis published before 31 August 2018. The literature search was conducted using research Methodology Filters. Expert commentary: The advantages of this single formulation over sequential administration include increased compliance, possibly reduced cost, and less likelihood of dosage-related issues. Moreover, this single tablet formulation combines the anti-inflammatory activity of the celecoxib with the systemic vasodilatation induced by the amlodipine. It is a promising treatment for patients with osteoarthritis and hypertension. Nevertheless, celecoxib may cause a variable degree of blood pressure increase and only a small clinical trial has been conducted before approval to assess interactions related to blood pressure effect between these two molecules
Hypertension after COVID-19 vaccination
No full textSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) rapidly spread across the world, killing more than 4 million individuals globally, with 240 million individuals being confirmed by laboratory tests. Among different therapeutic strategies to prevent SARS-CoV-2 infection, vaccines are the most promising approach for curbing the pandemic. They elicit an immune neutralizing response and thus offer protection against coronavirus disease 2019 (COVID-19). However, some questions regarding the safety of COVID-19 vaccines have been raised and based on sparse reports of severe systemic reactions after vaccination. Among these, evidences on the potential effect of vaccination on the acute rise in blood pressure have been recently accrued. Approved vaccines in Europe increase the endogenous synthesis of SARS-CoV-2 Spike proteins from a variety of cells. Once synthetized in the cells reached by the vaccine, the Spike proteins first assemble in the cytoplasm and then migrate to the cell surface to protrude with a native-like conformation. Spike proteins are recognized by the immune system which rapidly develops an immune response. Furthermore, the Spike proteins assembled in the cells which are eventually destroyed by the immune response circulate in the blood as free-floating forms. Free-floating Spike proteins may interact with angiotensin-converting enzyme 2 (ACE2) receptors leading to internalization, degradation, and dysregulation of the catalytic activities of these receptors. The consequent loss of ACE2 receptor activity leads to a rapid drop in the generation of angiotensin1,7 resulting from inactivation of angiotensin II. The imbalance between angiotensin II (overactivity) and of angiotensin1,7 (deficiency) might play a role in the genesis of acute elevation in blood pressure

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
