SYMPATHETIC NERVOUS SYSTEM AND BLOOD-PRESSURE CONTROL IN ESSENTIAL HYPERTENSION
1978
Abstract In normotensive subjects an inverse correlation was observed between an index of sympathetic nervous activity (the plasma-noradrenaline concentration during physical exercise) and reactivity to exogenous noradrenaline. This relationship was invariably disturbed in age-matched patients with essential hypertension. Multiple-regression analysis revealed a highly significant correlation between the combination of both factors and the height of mean arterial blood-pressure ( r =0·91). The findings suggest that sympathetic nervous activity and pressor response to noradrenaline together form an important determinant of the arterial blood-pressure level. An inverse relationship could be de…
Treatment of tension-type headache with articulatory and suboccipital soft tissue therapy: A double-blind, randomized, placebo-controlled clinical tr…
2013
This study researches the effectiveness of two manual therapy treatments focused on the suboccipital region for tension-type headache. A randomized double-blind clinical trial was conducted over a period of four weeks with a follow-up at one month. Eighty-four patients with a mean age of 39.7 years (SD 11.4) with tension-type headache were assigned to 4 groups which included the following manual therapy treatment: suboccipital soft tissue inhibition; occiput-atlas-axis global manipulation; combination of both techniques; and a control group. The primary assessment consisted of collecting socio-demographic data and headache characteristics in a one-month base period, data such as age, gender…
Inadequate Cytoplasmic Antioxidant Enzymes Response Contributes to the Oxidative Stress in Human Hypertension
2006
Untreated hypertensive patients show increased oxidative stress and decreased antioxidant enzyme activity in mononuclear cells. Therefore, the objective of this study was to determine whether or not the low antioxidant enzyme activity observed in mononuclear cells of hypertensive subjects is in part dependent on a defective activity of antioxidant mechanisms. Activity and mRNA level of antioxidant enzymes, CuZn- and Mn-superoxide dismutases, catalase, glutathione peroxidase type 1, and glutathione reductase were simultaneously measured in mononuclear cells of controls (n = 38) and hypertensive subjects (n = 35), in the absence of and during antihypertensive treatment. An increase in oxidati…
Lipid profile, cardiovascular disease and mortality in a Mediterranean high-risk population: The ESCARVAL-RISK study
2018
Introduction The potential impact of targeting different components of an adverse lipid profile in populations with multiple cardiovascular risk factors is not completely clear. This study aims to assess the association between different components of the standard lipid profile with all-cause mortality and hospitalization due to cardiovascular events in a high-risk population. Methods This prospective registry included high risk adults over 30 years old free of cardiovascular disease (2008–2012). Diagnosis of hypertension, dyslipidemia or diabetes mellitus was inclusion criterion. Lipid biomarkers were evaluated. Primary endpoints were all-cause mortality and hospital admission due to coron…
Evaluation of regional haemodynamics and alterations of vascular wall of the lower limbs in hypertensive subjects
1995
This study was designed to analyse the relationship between arterial hypertension and changes in arterial blood flow and vascular wall damage of the lower limbs in hypertensive patients with various degrees of hypertension. Six hundred and fifty-four hypertensive patients (421 males and 233 females) aged 35 to 70 years and 88 healthy subjects (63 males and 25 females) aged 39 to 60 years were studied. Strain-gauge plethysmography of the lower limbs was used to calculate arterial calf blood flow (RF), arterial calf blood flow after post-ischaemic hyperaemia (PF), basal and minimal vascular resistances (BVR and MVR), time to reach peak flow (tPF), time until 50% reduction of peak flow (tT1/2)…
Hypertension and the Fat-Soluble Vitamins A, D and E
2015
Hypertension affects populations globally and is thus a public health and socio-economic problem. Macronutrient and micronutrient deficiencies are common in the general population, and may be even more prevalent in hypertensive patients. This study aimed to determine a possible association between hypertension and intake of fat-soluble vitamins A, D and E. Participants were from the cross-sectional Hortega nutrition study conducted with a random sample of 1514 people (50.3% women, 49.7% men) and two groups: nonhypertensive controls ≥40 years old (n = 429
Abnormal BAEP and internal auditory canal MRI in intracranial hypotension
2017
Intracranial hypotension (IH) is a treatable condition due to cerebrospinal fluid leak, characterised by variable clinical and MRI findings.1 Positional headache, neck stiffness, hearing changes with subdural fluid collection, enhancement of meninges, engorgement of venous structures and brain sagging are among the most frequent clinical and MRI findings. Typical abnormalities are found in 68%–85% of patients1. Hearing alterations (ranging from misperception to severe hearing loss) are known clinical symptoms of IH.1 The mechanism involves secondary perilymph depression due to patency of the cochlear aqueduct, inducing a compensatory expansion of the endolymphatic compartment, decreasing ba…
Changes in strength and power performance and serum hormone concentrations during 12 weeks of task-specific or strength training in conscripts.
2020
Abstract The purpose of this study was to investigate the effects of two different training programs on strength and power performance and serum hormone concentrations. A total of 104 male soldiers volunteered and took part in the 12‐week training period with baseline, mid‐, and post‐measurements of body composition, muscle strength, lower and upper body power, and blood samples to determine serum hormone concentrations. The mean (±SD) age of subjects was 20 ± 1 years, height 180 ± 6 cm and body mass 72.4 ± 8.8 kg. The subjects were divided into three different training groups: soldier task‐specific training (TS), strength training (ST), and control (CON). Each group had a total of 18 train…
Cardiovascular medication and intraocular pressure: results from the Gutenberg Health Study
2016
BACKGROUND Intraocular pressure (IOP) is well known to be associated with blood pressure and other cardiovascular risk factors. The influence of systemic cardiovascular, in particular antihypertensive, medication on IOP is still controversial. This study analyses the association between the use of cardiovascular medications and IOP in a large European cohort. METHODS The Gutenberg Health Study is a population-based, prospective,observational cohort study in mid-western Germany. IOP was measured using a non-contact tonometer. The medication classes examined were peripheral vasodilators, diuretics, β-blockers (overall, selective and non-selective), calcium channel blockers, renin-angiotensin …
Analysis of Autoantibodies Against Human Retinal Antigens in Sera of Patients with Glaucoma and Ocular Hypertension
2008
The aim of this study was to show that complex antibody patterns against retinal antigens in sera of patients with glaucoma, found in previous studies, are autoantibodies against human antigens.Sera of 179 patients were collected at the Department of Ophthalmology (University of Mainz, Germany): non-glaucomatous control patients (n=45), primary open-angle glaucoma (n=45), ocular hypertension (n=44), and normal tension glaucoma patients (n=45). The sera were tested against Western blots of human retinal antigens. IgG antibody patterns were analyzed by multivariate statistical techniques, and some significant antigens were identified by mass spectrometry.All subjects, even healthy ones, showe…
