Dietary fructose in relation to blood pressure and serum uric acid in adolescent boys and girls

EditorialPor: K S Bobridge, G L Haines, T A Mori, L J Beilin, W H Oddy, J Sherriff y T A O’Sullivan.  Journal of Human Hypertension (2013) 27, 217–224.

Evidence that fructose intake may modify blood pressure is generally limited to adult populations. This study examined cross-sectional associations between dietary intake of fructose, serum uric acid and blood pressure in 814 adolescents aged 13–15 years participating in the Western Australian Pregnancy Cohort (Raine) Study. Energy-adjusted fructose intake was derived from 3-day food records, serum uric acid concentration was assessed using fasting blood and resting blood pressure was determined using repeated oscillometric readings.  [Actualizado: 18 de marzo 2013]

Hypertension and the J-curve phenomenon: implications for tight blood pressure control

ComentandoPor: Fabio Angeli, Gianpaolo Reboldi y Paolo Verdecchia. Hypertension Research (2013) 36, 109–111.

The term J-curve is used in several fields of science to refer to a variety of J-shaped diagrams where a curve initially falls, but then rises to higher levels. In cardiovascular (CV) medicine, the J-curve phenomenon arises when a risk factor becomes inversely related to risk below a certain point, whereas the more widely accepted positive risk association exists across most of the observed risk factor distribution. In simpler terms, when elevated blood pressure (BP) is lowered, the risk of CV events decreases, but lowering BP below a critical ‘nadir’ is no longer beneficial and possibly deleterious, thus shaping a J-curve. This phenomenon was originally described for diastolic BP by Stewart in 169 well-matched hypertensive patients treated and followed for 6.25 years. [Actualizado: 26 de febrero de 2013]

Blood Pressure Variability in Elderly Persons With White-Coat and Masked Hypertension Compared to Those With Normotension and Sustained Hypertension

EditorialPor: Cécilia Cacciolati, Christophe Tzourio, y Olivier Hanon. American Journal of Hypertension, volume 26, issue 3, pp. 367-372.

The relationship between blood pressure (BP) measured, its variability, and risk of cardiovascular events is well established; however, it is not well known whether there is a difference of variability between the four categories of BP status obtained by the comparison of office and home BP measurements: normotension and masked, white-coat, and sustained hypertension. Here, we assessed BP variability (BPV) according to BP status in the elderly.   In elderly individuals, the short-term variability of BP is similar in masked and sustained hypertension and higher than in normotension and white-coat hypertension. This result suggests the hypothesis that BPV among persons with masked hypertension may contribute to the elevated cardiovascular risk observed in this BP pattern. [Actualizado: 21 febrero 2013]

Rationale, study design, baseline characteristics and blood pressure at 16 weeks in the HONEST Study

EditorialPor: Ikuo Saito, Kazuomi Kario, Toshio Kushiro, Satoshi Teramukai, Natsuko Zenimura, Katsutoshi Hiramatsu, Fumiaki Kobayashi y Kazuyuki Shimada. Hypertension Research (2013) 36, 177–182.

Large-scale clinical studies have demonstrated that lowering clinic blood pressure (CBP) in hypertensive patients with antihypertensive drug therapy reduces the incidence of cardiovascular (CV) events.
Thus, strict management of blood pressure (BP) is recommended for hypertensive patients in the Japanese Society of Hypertension Guidelines for the Management of Hypertension (JSH2009).
Home BP (HBP) measurement has been reported to be more useful than CBP for the appropriate diagnosis, treatment and prediction of future CV events.4–9 HBP measurement is also widely accepted in Japan. Systematic reviews by Stergiou et al.12 and Ward et al.13 confirmed that baseline HBP has a stronger prognostic ability for future CV events compared with CBP; however, few studies have investigated the relationship between on-treatment HBP and CV events in hypertensive patients.
