Inverse association between type 2 diabetes and aortic root dimension in hypertensive patients

2017

Background Some data support the concept that aortic root diameter (ARD) in hypertension may be regarded as a marker of subclinical organ damage. The impact of type 2 diabetes mellitus (DM) on cardiac structure and function is known, although the relationship between DM and ARD is not clear. The aim of our study was to evaluate the influence of DM on ARD in hypertensive patients. Methods We enrolled 1693 hypertensive patients (aged 63.7 ± 9.6 years). The population was divided into two groups: the first one with DM (n = 747) and the second one without DM (n = 946). ARD was measured by echocardiography at level of Valsalva's sinuses using echocardiography M-mode tracings. It was considered a…

Identification of a plausible serum uric acid cut-off value as prognostic marker of stroke: the Uric Acid Right for Heart Health (URRAH) study

2021

The Working Group on Uric Acid and Cardiovascular Risk of the Italian Society of Hypertension conceived and designed an ad hoc study aimed at searching for prognostic cut-off values of serum uric acid (SUA) in predicting combined (fatal and non-fatal) cerebrovascular (CBV) events in the whole database. The URic acid Right for heArt Health study is a nationwide, multicenter, observational cohort study involving data on subjects aged 18-95 years recruited on a regional community basis from all the territory of Italy under the patronage of the Italian Society of Hypertension with a mean follow-up period of 120.7 ± 61.8 months. A total of 14,588 subjects were included in the analysis. A prognos…

FRI0628 DIAGNOSTIC VALUE OF OPTICAL SPECTRAL TRANSMISSION IN PATIENTS WITH RHEUMATOID ARTHRITIS: CORRELATIONS WITH DISEASE ACTIVITY, EPIDEMIOLOGIC AN…

2019

Background Valid assessment of disease activity leads to improvement of long-term outcomes in patients with rheumatoid arthritis (RA) (1). Clinical disease activity assessment tools such as the Disease Activity Score 28 (DAS28) are partially subjective and do not always depict the real inflammatory burden. Ultrasound (US) and Hand-MRI are important diagnostic modalities which can nevertheless be time consuming (US, MRI), expensive (MRI) or usually performed unilaterally (MRI). Thus, further diagnostic tools are needed. Optical spectral transmission (OST) is a new modality able to assess the blood-specific absorption of light transmitted through a tissue promising quantification of inflammat…

Mild obstructive sleep apnoea (OSA) and arterial hypertension in the EuropeanSleep Apnoea Database (ESADA) cohort study.

2018

Background: Mild obstructive sleep apnoea (OSA) is highly prevalent, however its association with important clinical outcomes like arterial hypertension remains unknown. Aims and Objectives: To investigate the association between mild OSA and arterial hypertension in the European Sleep Apnoea Database (ESADA) cohort after adjusting for relevant confounding factors. Methods: A multicentric sample of 4974 adults from the ESADA cohort who showed simple snoring or mild OSA at cardiorespiratory polygraphy was studied. We compared the predictive value of mild OSA (AHI 5- Results: Arterial hypertension prevalence was 37% in mild OSA patients (n=2457) compared to 20% in non-apnoeic snorers (n=2517,…

Effectiveness of a home exercise programme in low back pain: a randomized five-year follow-up study

2007

Background and Purpose. Therapeutic exercise has been shown to be beneficial in decreasing pain and in increasing functioning in patients with chronic low back pain. However, longitudinal follow-up studies are small in number, and often limited in the numbers of subjects due to drop-outs. In addition there is a shortage of real control groups in most cases. The purpose of the present study was to describe long-term changes in intensity of low back pain and in functioning for two study groups five years after undertaking a home exercise programme. Method. This was a randomized follow-up study over five years. Fifty-seven subjects were reassessed with questionnaires five years after their ini…

ObjectivesYoung age at school entry (ASE) for students has been related to their impaired mental health in higher grades. To avoid the negative health consequences of young ASE, preschool examinations and individual school entry deferral for young children are routinely performed by some school authorities. We aimed to investigate whether ASE was associated with attention-deficit hyperactivity disorder (ADHD)-related symptoms in pupils attending schools using a selective school enrolment procedure.DesignProspective open cohort study with baseline assessments at school entry and two follow-ups in the second and fourth grades.SettingUp to 128 Rudolf Steiner Schools (Waldorf Schools) located w…

Combining Body Mass Index With Measures of Central Obesity in the Assessment of Mortality in Subjects With Coronary Disease

2013

Objectives This study sought to assess the mortality risk of patients with coronary artery disease (CAD) based on a combination of body mass index (BMI) and measures of central obesity. Background In CAD patients, mortality has been reported to vary inversely with BMI (“obesity paradox”). In contrast, central obesity is directly associated with mortality. Because of this bi-directional relationship, we hypothesized that CAD patients with normal BMI but with central obesity would have worse survival compared with subjects with other combinations of BMI and central adiposity. Methods We included 15,547 participants with CAD who took part in 5 studies from 3 continents. Multivariate stratified…

The Relationship between an Oxidative Stress Biomarker and Plasma Haemoglobin in Patients with Chronic Kidney Disease

2010

Introduction: Evidence suggests that decreased haemoglobin plasma concentration may be a predictor of adverse cardiovascular events in patients with chronic kidney disease (CKD). We hypothesized that in CKD patients, oxidative stress could influence the development of cardiovascular damage via a relationship with haemoglobin levels. Methods: We assayed plasma levels of the biomarker of oxidative stress 8-ISO-prostaglandin F2α (8-ISO-PGF2α) and of haemoglobin in 193 stage 2–5 CKD patients, investigating their relationship. Eighty healthy subjects and 80 patients with primary hypertension having normal renal function were enrolled as controls. Results: The CKD group was divided according to 8…
