A centennial of two great discoveries in the history of medicine: hyperpiesis and the sphygmomanometer (1896-1996) [Cien años de dos grandes acontecimientos en la historia de la medicina: hiperpiesis y esfigmomanómetro (1896-1996).]
No full textThis paper describes two outstanding contributions in the understanding and treatment of primary arterial hypertension and cardiovascular diseases. In 1896, Sir T. Clifford Allbutt reported a series of clinical cases associated with high intensity in the arterial pulse and no renal damage. He named this hyperpiesis to distinguish it from Bright's disease or chronic renal insufficiency. In the same year, Scipione Riva-Rocci invented the Sphygmomanometer which, in principle, is still used today. Also, this paper describes the research work which would lead to the development of the blood pressure measurement device. This development is as significant now as it was then

Suspension of doxazosin use implications for arterial hypertension treatment [Implicaciones de la suspensión del uso de la doxazosina en el tratamiento de la hipertensión arterial]
No full textOld antihypertensive drugs that have demonstrated to reduce cardiovascular morbidity and mortality persist like an efficient alternative for managing hypertensive patients. The use of new drugs, which are necessaries, will require an intense study before they can be used in the daily practice

Is the cardioprotector effect of estrogens useful in the menopause? [¿Es útil el efecto cardioprotector de los estrógenos en la menopausia?]
No full textTendency of coronary mortality to occur about 10 years later in women than in men is a well known fact. This difference has been attributed to the presence of estrogens in women. Despite the performance of many experimental and observational studies on the heart-protecting effect of estrogens, there are a lot of methodological limitations which make it difficult to obtain definitive results. This revision, shows the experimental studies where it has been demonstrated that estrogens do not increase cardiovascular protection. Emphasis is focused on adverse effects, such as the development of breast and endometrial cancer. It is also emphasized that during menopause, a series of life style modifications can be implemented, such as exercising, stop smoking and loosing weight. Undoubtedly, the results will be cardiovascular health benefits, with minimum integral health risks. © 2006 Federación Mexicana de Ginecología y Obstetricia

Changes in the costs of antihypertensive medications in a developing country: A study in Mexico comparing 1990 and 1996
No full textIn developing countries, the cost of antihypertensive medications is one of the principal limiting factors when trying to treat patients with high blood pressure. To determine the changes in cost (in US dollars) of these medications and in the percentage of the minimum wage needed to purchase them, two cost studies (1990 and 1996) done in Mexico were compared. The yearly cost of a treatment with hydrochlorothiazide was US 10.92. Both figures represent 1.1% of the minimum wage that was in effect at the time. Propranolol hydrochloride cost US 66.12 for the same in 1996. These figures represented, respectively, 4.2% and 6.7% of the minimum wage of 1990 and 1996. The annual cost for nifedipine was US 242.16 in 1996 (24.8% of the minimum wage). The yearly cost of enalapril was US 433.20 in 1996; these costs represented, respectively, 19.4% and 44.2% of the minimum wage. The comparison of these two cost studies (1990 and 1996) shows why Mexico's population is finding it more difficult to purchase antihypertensive medications. Higher costs and reduced purchasing power seem to be the two principal factors causing this. This is probably affecting the population's health, as it is more difficult to control high blood pressure without proper treatment
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
