Review Meta AnalysisPrevalence of simultaneously measured interarm systolic blood pressure difference and its clinical and demographic predictors: a systemic review and meta-analysis.
Prevalence of interarm systolic blood pressure difference and clinical and demographic characteristics associated with interarm systolic blood pressure difference (IASBPD) have been a matter of debate. We aimed to ascertain the prevalence of IASBPD and clinical and demographic characteristics associated with it. We searched PubMed, EMBASE, and CINAHL, Ovid and Cochrane Library, and Google Scholar. ⋯ After BMI, hypertension and dyslipidemia had strongest association with IASBPD, but results were not statistically significant. IASBPD is relatively prevalent, but prevalence is lower than that previously reported. Prevalence is higher when blood pressure is measured in hospital setting compared with outpatient and community setting.

ReviewClock genes in hypertension: novel insights from rodent models.
The circadian clock plays an integral role in the regulation of physiological processes, including the regulation of blood pressure. However, deregulation of the clock can lead to pathophysiological states including hypertension. ⋯ The goal of this review is to provide an introduction and general overview into the role of circadian clock genes in the regulation of blood pressure with a focus on their deregulation in the etiology of hypertension. This review will focus on the core circadian clock genes CLOCK, BMAL1, Per, and Cry.

ReviewOscillometric sphygmomanometers: a critical appraisal of current technology.
Blood pressure (BP), a key vital sign, monitors general health. Oscillometric devices are increasingly used for measurement, although their accuracy continues to be critically debated. A functional block diagram is used to review the components that affect accuracy. ⋯ The indirect nature of BP measurement poses particularly problems for ensuring accuracy. Critical assessment has done much to improve standards, but a solid theoretical understanding of the technique has not been formulated and further work is required.

ReviewAssessment of the validation of blood pressure monitors: a statistical reappraisal.
Protocols to determine the accuracy of noninvasive blood pressure monitors have been published by the Association for the Advancement of Medical Instrumentation, the British Hypertension Society, and the European Society of Hypertension (ESH). We compared the statistical basis for each of these protocols. Although the Association for the Advancement of Medical Instrumentation and British Hypertension Society protocols require a minimum of 85 participants, the ESH protocol requires only 33 participants. The reduced sample size results in a reduction in statistical power from 98 to 70%, which brings into question the applicability of the ESH (International) protocol.

ReviewBlood pressure measurement and the guidelines: a proposed new algorithm for the diagnosis of hypertension.
Current hypertension guidelines continue to base management decisions on the office BP as recorded by mercury sphygmomanometry. The imminent disappearance of mercury from the workplace for environmental and safety reasons provides an opportunity to re-assess how a diagnosis of hypertension is made. There are now several validated, automated BP recording devices available to replace mercury sphygmomanometers in the office setting. Self/home and 24-hour ambulatory BP monitoring should now become an integral part of the diagnostic algorithm for hypertension in view of their superior ability to predict clinical outcomes when compared to traditional office BP measurements.
