Sleep apnoea severity independently predicts glycaemic health in nondiabetic subjects: the ESADA study
2014
Abstract: Obstructive sleep apnoea (OSA) is associated with increased risk of dysglycaemia but the intimate link of these conditions with obesity makes discerning an independent relationship between them challenging. Glycosylated haemoglobin (HbA1c) levels predict adverse cardiovascular outcomes in nondiabetics but there is a lack of population-level data exploring the relationship of HbA1c with OSA. A cross-sectional analysis of 5294 participants in the multinational European Sleep Apnoea Cohort (European Sleep Apnoea Database) study was performed, assessing the relationship of OSA severity with HbA1c levels in nondiabetic subjects, with adjustment for confounding factors. HbA1c levels cor…
Plasma viscosity and related cardiovascular risk factors in a Spanish Mediterranean population
2006
Plasma viscosity (PV) constitutes an independent important predictor of initial and recurrent cardiac events and mortality. It has been suggested that there is a geographical variation in PV values related to coronary event rates. Little information exists regarding PV in Spain. Therefore, our objective was to determine PV in a large sample of randomly selected subjects from the Spanish population and to study which demographic or cardiovascular risk factors (CVRF) influence levels of PV in this population.1277 subjects (503 males, 774 females) aged 43+/-14 years (range: 20-70) were randomly selected from an Eastern Spanish population. These subjects were free of cardiovascular diseases and…
Long-Term Impact of Systolic Blood Pressure and Glycemia on the Development of Microalbuminuria in Essential Hypertension
2005
The objective was to assess the temporal impact of factors related to the development of microalbuminuria during the follow-up of young adult normoalbuminurics with high-normal blood pressure or at stage 1 of essential hypertension. Prospective follow-up was conducted on 245 normoalbuminuric hypertensive subjects (mean age 40.9 years; 134 men; blood pressure 139.7/88.6 mm Hg; body mass index 28.5 kg/m 2 ) never treated previously with antihypertensive drugs, with yearly urinary albumin excretion measurements, until the development of microalbuminuria. After enrollment, patients were placed on usual care including nonpharmacological treatment or with an antihypertensive drug regime to achie…
Chronic Hyperinsulinemia Does Not Increase the Production Rate of High-Density Lipoprotein Apolipoprotein AI
2013
Objective— In vitro studies showed that insulin stimulates the production of apolipoprotein AI (apoAI). Thus, we hypothesized that chronic hyperinsulinemia could contribute to the increase in the production of high-density lipoprotein apoAI that is observed in metabolic syndrome. Approach and Results— We performed an in vivo kinetic study with stable isotope in 7 patients with insulinoma who showed hyperinsulinemia but no insulin resistance, 8 patients with insulin resistance, and 16 controls. Insulinemia was 3.1× ( P <0.01) higher in patients with insulinoma or insulin resistance than in controls in the fasting state and, respectively, 3.5× and 2.6× ( P <0.05) higher in the fed stat…
Population attributable risk for ovarian cancer
2000
Parity, oral contraceptive (OC) use, age at menopause, a family history of the disease and selected aspects of diet have been related to the risk of ovarian cancer. The quantification of their impact on a population level may help focus and rank the importance of potential prevention strategies. Using data from a case-control study conducted in Italy between 1983 and 1991 on 971 ovarian cancer cases and 2758 control women we computed the multivariate relative risk estimates, and population attributable risks (PARs), i.e. the proportion of ovarian cancers that would have been avoided if a given exposure had not been present in the population. Overall, the PARs were 5% for nulliparity, 12% fo…
The Effectiveness of EMOVERE: An Emotional Education Program for Young Couples
2021
Our aim was to assess the effectiveness of EMOVERE, a psychoeducational and experiential program to increase emotion regulation in couples. Forty-four young couples (n = 88) aged between 18 and 36 years old participated in the study (53.4% women
Emotional intelligence and self-efficacy: effects on psychological well-being in college students.
2013
AbstractThe present paper examined the role of perceived emotional intelligence-EI- (measured by adaptations of the Trait Meta-Mood Scale - TMMS, Salovey, Mayer, Goldman, Turvey, & Palfai, 1995) as a predictor of life satisfaction and mental health. We explored the unique contribution of EI dimensions (Attention, Clarity and Repair) on individuals’ psychological well-being, after controlling for the influence of general self-efficacy and socio-demographic variables (age, gender and culture). Data was collected from a sample of 1078 Spanish, Mexican, Portuguese and Brazilian undergraduate students (Mage = 22.98; SD = 6.73) and analyzed using hierarchical multiple regressions. Results ind…
Serum and ascitic fluid bacterial DNA: a new independent prognostic factor in noninfected patients with cirrhosis.
2008
We tested the hypothesis that the presence of bacterial DNA (bactDNA) in ascitic fluid and serum is associated with decreased survival in patients with cirrhosis. In a prospective, multicenter study, we analyzed the clinical evolution of 156 patients with cirrhosis and ascites (first or recurrence) with lower than 250 polymorphonuclear cells (PMN)/L, negative ascites bacteriological culture, and absence of other bacterial infections being admitted for evaluation of largevolume paracentesis, according to the presence of bactDNA at admission. Survival, causes of death, and successive hospital admissions were determined during a 12-month follow-up period. BactDNA was detected in 48 patients. T…
Daily follow-up of bacterial communities in the human gut reveals stable composition and host-specific patterns of interaction
2012
In the last decade, an extensive effort has been made to characterize the human intestinal microbiota by means of SSU rRNA gene sequence and metagenomic analysis. Relatively few studies have followed intestinal bacterial communities over time to assess their stability in the absence of perturbation. In this study, we have monitored the faecal bacteria of three healthy subjects during 15 consecutive days. The global community structure was analysed through SSU rRNA gene sequencing. In agreement with previous studies, we found that the between-subject variation in community structure was larger than within. The composition was fairly stable throughout, although daily fluctuations were detecte…
Clinical and Microbiologic Effects of Subgingival Controlled-Release Delivery of Chlorhexidine Chip in the Treatment of Periodontitis: A Multicenter …
2008
Background: The main therapeutic approach for periodontal diseases is mechanical treatment of root surfaces via scaling and root planing (SRP). Multicenter clinical trials have demonstrated that the adjunctive use of a chlorhexidine (CHX) chip is effective in improving clinical results compared to SRP alone. However, some recent studies failed to confirm these clinical results, and conflicting results were reported regarding the effects of the CHX chip on subgingival microflora. The aim of this study was to provide further data on the clinical and microbiologic effects of CHX chips when used as an adjunct to SRP. Methods: A total of 116 systemically healthy individuals with moderate to adva…
