Cardiovascular Risk Profile in 14.513 patients with essential hypertension followed by Italian specialist physicians
No full textBackground: Recent data clearly demonstrated that in Western countries control of blood pressure and modifiable cardiovascular risk factors in the hypertensive population is rather poor and far from being satisfactory.
Aim: The Observational Pressure Survey (OPS) was planned to assess control of blood pressure and the major modifiable risk factors within a large Italian hypertensive population, aged ≥60 years, followed by hypertension specialists.
Results: Systolic blood pressure was controlled below 140mm Hg in only 30.2% of males and 29.9% of females, while diastolic blood pressure was controlled below 90mm Hg in 63.9% of males and 67.8% of females. According to the most recent classification of the European guidelines on hypertension, only 4.8% of the patients had optimal to normal control, whereas 9.7% had high-normal level of blood pressure, and 70% had grade 1–3 hypertension, despite treatment. Also, the control of cardiovascular modifiable risk factors associated with hypertension appeared rather poor in the study. In particular, total cholesterol levels were found to be <200 mg/ dL in approximately 30% of the overall population.
Conclusions: The results of the present OPS survey, performed in a hypertensive population routinely followed by specialist physicians, confirm and extend the existing data obtained in other studies, and highlight the need for specific and effective actions directed to modify this negative situation and improve the level of blood pressure control in Italy. Accordingly, this survey suggests that guidelines for treatment of hypertension and cardiovascu- lar risk need to be substantially implemented, not only at the level of general practitioners, but also at the level of specialist physicians

Clinical management of resistant hypertension: practical recommendations from the Italian Society of Hypertension (SIIA).
No full textAccording to recent hypertension guidelines, resistant hypertension is a clinical condition characterized by the presence of BP values above the recommended limits of the reference values (BP >140/90 mmHg). The prevalence of this clinical condition is about 10 % of the essential hypertensives. A proper diagnosis and management of resistant hypertension should go trough careful, mandatory clinical step, aimed at excluding the presence of pseudo-resistance hypertension. In this report, we summarized the practical recommendations are targeting both the general practitioner and the specialist who play an active role in the clinical management of patients with arterial hypertension
Performance of the AM-5600 blood pressure monitor: comparison with ambulatory intra-arterial pressure
No full text Omboni, Stefano, Gianfranco Parati, Antonella Groppelli, Luisa Ulian, and Giuseppe Mancia. Performance of the AM-5600 blood pressure monitor: comparison with ambulatory intra-arterial pressure. J. Appl. Physiol. 82(2): 698–703, 1997.—The AM-5600 is a new device that simultaneously monitors electrocardiogram (ECG) and noninvasive blood pressure (BP) over a 24-h period. BP readings (Korotkoff sounds and cuff air pressure) are stored into the recorder, allowing the removal of BP artifacts after a visual check. In 12 subjects with essential hypertension, we compared BP values simultaneously provided by the AM-5600 and intra-arterial recordings. At rest, noninvasive systolic BP (SBP) values were lower (5.4 ± 4.9 mmHg) and diastolic BP (DBP) values were higher (7.3 ± 7.3 mmHg) than were intra-arterial values. In ambulatory conditions (9 subjects), between-method discrepancies were +0.8 ± 6.1 and +12.2 ± 7.4 mmHg for 24-h SBP and DBP, respectively. AM-5600 underestimated 24-h intra-arterial SBP and DBP SD, but it accurately tracked intra-arterial SBP and DBP changes. Editing removed 22.1% of total readings, slightly reducing between-method discrepancies. Thus the AM-5600 provides an accurate average estimate of resting and ambulatory SBP and, for DBP, a less accurate estimate that is slightly improved by editing. The AM-5600 allows accurate description of SBP and DBP profiles and thus may be suitable to describe the abrupt BP changes accompanying a number of clinical events. </jats:p
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
