Short-Term but not Long-Term Blood Pressure Variability Is a Predictor of Adverse Cardiovascular Outcomes in Young Untreated Hypertensives.

Background: Whether blood pressure variability (BPV) measured with ambulatory monitoring (short-term BPV) or computed from office visits (long-term BPV) are related to each other and carry similar prognostic information is not well known. We investigated the independent determinants of short-term and long-term BPVs and their predictive capacity for the development of major adverse cardiovascular and renal events (MACEs) in a cohort of young hypertensive participants.

Methods: Long-term BPV was calculated as visit-to-visit SD and average real variability from office blood pressure (BP) measured during 7 visits, within 1 year.

Short-term blood pressure variability outweighs average 24-h blood pressure in the prediction of cardiovascular events in hypertension of the young.

Objective: The association of short-term blood pressure (BP) variability (BPV) with cardiovascular events (CVEs) is controversial. Aim of this study was to investigate whether BPV measured as weighted 24-h SD was associated with CVE in a prospective cohort study of young patients screened for stage 1 hypertension.

Methods: We performed 24-h ambulatory BP monitoring in 1206 participants aged 33.

Clinical characteristics and risk of hypertension needing treatment in young patients with systolic hypertension identified with ambulatory monitoring.

Objective: The clinical significance of isolated systolic hypertension (ISH) in youth is controversial. One main confounding factor is the strong white-coat effect often observed in ISH patients. The aim of this study was to investigate the risk of hypertension needing pharmacological treatment in ISH identified with ambulatory 24-h blood pressure (24-h BP).

Low night-time heart rate is longitudinally associated with lower augmentation index and central systolic blood pressure in hypertension.

Purpose: Several studies have shown that the augmentation index (AIx) is negatively correlated with heart rate (HR). This led some authors to claim that the use of HR-lowering drugs may be detrimental in hypertension. The aim of this study was to assess the longitudinal and cross-sectional relationships of HR with AIx and central blood pressure (BP) in 346 subjects from the HARVEST (mean age 30.

Office Pulse Pressure Is a Predictor of Favorable Outcome in Young- to Middle-Aged Subjects With Stage 1 Hypertension.

Neutron reflectivity measurement of protein A-antibody complex at the solid-liquid interface.

Chromatography is a ubiquitous unit operation in the purification of biopharmaceuticals yet few studies have addressed the biophysical characterisation of proteins at the solution-resin interface. Chromatography and other adsorption and desorption processes have been shown to induce protein aggregation which is undesirable in biopharmaceutical products. In order to advance understanding of how adsorption processes might impact protein stability, neutron reflectivity was used to characterise the structure of adsorbed immunoglobulin G (IgG) on model surfaces.

Alcohol Intake More than Doubles the Risk of Early Cardiovascular Events in Young Hypertensive Smokers.

Coffee consumption and risk of cardiovascular events in hypertensive patients. Results from the HARVEST.

Background: Controversy still exists about the long-term cardiovascular effects of coffee consumption in hypertension.

Methods: The predictive capacity of coffee use for cardiovascular events (CVEs) was investigated in 1204 participants from the HARVEST, a prospective cohort study of non-diabetic subjects aged 18-45years, screened for stage 1 hypertension. Subjects were grouped into three categories of coffee drinking, non-drinkers (none), moderate drinkers (1 to 3cups/day) and heavy drinkers (4or more cups/day).

Protein A chromatography increases monoclonal antibody aggregation rate during subsequent low pH virus inactivation hold.

Protein A chromatography is a near-ubiquitous method of mAb capture in bioprocesses. The use of low pH buffer for elution from protein A is known to contribute to product aggregation. Yet, a more limited set of evidence suggests that low pH may not be the sole cause of aggregation in protein A chromatography, rather, other facets of the process may contribute significantly.

Association of coffee consumption and CYP1A2 polymorphism with risk of impaired fasting glucose in hypertensive patients.

Whether and how coffee use influences glucose metabolism is still a matter for debate. We investigated whether baseline coffee consumption is longitudinally associated with risk of impaired fasting glucose in a cohort of 18-to-45 year old subjects screened for stage 1 hypertension and whether CYP1A2 polymorphism modulates this association. A total of 1,180 nondiabetic patients attending 17 hospital centers were included.

Regular physical activity is associated with improved small artery distensibility in young to middle-age stage 1 hypertensives.

The aim of the present study was to investigate the association of physical activity with small artery elasticity in the early stage of hypertension. We examined 366 young-to-middle-age stage 1 hypertensives (mean blood pressure 145.6±10.

Antioxidant assays - consistent findings from FRAP and ORAC reveal a negative impact of organic cultivation on antioxidant potential in spinach but not watercress or rocket leaves.

Watercress (Rorippa nasturtium-aquaticum), wild rocket (Diplotaxis tenuifolia), and spinach (Spinacia oleracea) are commercial crops reported to have high concentrations of antioxidants, possibly contributing to disease prevention following human consumption. Following analysis of supermarket-purchased salad leaves, we report the antioxidant content potential of these species using two comparable techniques assessing the consistency between the assays - by the ferric reducing antioxidant power (FRAP) assay and the oxygen radical absorbance capacity (ORAC) assay. The leaves were harvested from both conventionally and organically managed crops, to investigate whether organic agriculture results in improved crop quality.
