Severe hypertension in the emergency room. An integral assessment [Hipertensión arterial severa en urgencias. Una evaluación integral]
No full textPatients frequently come to the emergency room with severe high blood pressure; this can be asymptomatic or accompanied by diverse clinical manifestations that create a certain level of confusion when trying to determine if the high blood pressure is the cause or consequence of the patient's clinical problem. Due to the chaotic situation and oversaturation of emergency services in many clinics and hospitals, and the lack of specific national or international guidelines to treat these patients, they frequently are not properly evaluated and receive inadequate or insufficient treatment. The term "hypertensive crisis" is still generically used to identify individuals with severe high blood pressure, and little effort is spent to properly classify them, depending on the presence or absence of concomitant cardiovascular damage. There are three clinical situations that should be distinguished: uncontrolled severe hypertension, hypertensive urgency and hypertensive emergency, in order to choose the most appropriate treatment to low the blood pressure, as each clinical scenario implies a different follow-up and prognosis
Commentaries on the treatment of hypertension [Comentarios respecto del tratamiento de la hipertensión arterial]
No full textHypertension is one of the most prevalent cardiovascular risk factors in the world. Its treatment and control have been proved to markedly reduce cardiovascular morbid-mortality. During the last few years the patient percentage management of well controlled individuals (BP < 140/90 mmHg), but is still too low. There are a myriad of reasons that explain this phenomenon. One very important reason is that the general and specialist physician are not making optimal use of the available pharmacological therapeutics in order to obtain greater arterial hypertension control. The purpose of this paper is to comment on some of the most important situations related to the treatment of hypertension and to make a few recommendations that are put into practice in a hypertension clinic, but can be used in daily practice with patients at any attention level for this illness

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
Diagnosis and management of the hypertensive crisis [Diagnóstico y tratamiento de la crisis hipertensiva]
No full textPatients presenting to emergency departments with severe hypertension need prompt evaluation to establish the presence of a hypertensive emergency or urgency. Patients with hypertensive emergencies have severe hypertension and constitute a distinct group of clinic pathologic entities associated with acute target organ injury. These patients require immediate blood pressure reduction to prevent progressive end-organ damage and are best treated in an intensive care unit with treatable parenteral hypotensive agents. Those with hypertensive urgencies can be managed on an ambulatory basis with initiation or adjustment of appropriate oral antihypertensive therapy. There is no predetermined level for the goal of therapy; however, special care should be taken to avoid abrupt hypotension. There are a number of highly effective drugs available to treat patients experiencing these crises
