Increased levels of C-reactive protein and fibrinogen influence the risk of vascular events in patients with NIDDM
2004
AIM: To evaluate the predictive role of hs-CRP and fibrinogen for cardio- and cerebrovascular events in a population of patients with type 2 diabetes. METHODS: We studied 156 patients with type 2 diabetes, mean age 66+10 years, and 156 sex and age matched control subjects. Patients underwent physical examination, EKG, measurement of body mass index and blood pressure. A blood sample was drawn to evaluate glycaemia, total and HDL/LDL cholesterol, triglycerides, high sensitive C-reactive protein (hs-CRP), fibrinogen. Finally, patients underwent an ecocolordoppler examination of the common carotid arteries until the bifurcation. In a follow-up of 5+/-1.2 years we evaluated the following events…
Comparison between euglycemic hyperinsulinemic clamp and surrogate indices of insulin sensitivity in children with growth hormone deficiency
2018
Objective: Data about the impact of growth hormone treatment (GHT) on insulin sensitivity in children are quite controversial, due to the different surrogate indices that have been used. Design: We evaluated insulin sensitivity through the euglycemic hyperinsulinemic clamp, considered the gold standard technique, in 23 children affected by growth hormone deficiency (GHD) at baseline and after 12. months of GHT and in 12 controls with short stature at baseline, and we compared the clamp-derived index (M-value) with the most commonly used surrogate index of insulin sensitivity, as ISI Matsuda, and with circulating plasma markers of insulin sensitivity, as adiponectin and resistin levels. Resu…
Arterial stiffness indexes and serum cytokine levels in seronegative spondyloarthritis: relationships between stiffness markers and metabolic and imm…
2015
Objective: The aim of this study was to investigate the relationship between immunoinflammatory markers and indexes of arterial stiffness in patients with seronegative spondyloarthritis (SpA).Method: We enrolled consecutive patients with inflammatory seronegative SpA referred to a rheumatology outpatient clinic. Control subjects were patients admitted in the same period for any cause other than chronic inflammatory disease or acute cardiovascular and cerebrovascular events. Carotid-femoral pulse wave velocity (PWV) was measured and the aortic pressure waveform was used to calculate the augmentation index (Aix). We also evaluated plasma levels of C-reactive protein (CRP), interleukin (IL)-1β…
Omega-6 and omega-3 polyunsaturated fatty acid levels are reduced in whole blood of Italian patients with a recent myocardial infarction: the AGE-IM …
2014
Abstract Objective The relationship between whole blood fatty acids and myocardial infarction (MI) risk has not been analyzed in detail, especially in Mediterranean countries. The AGE-IM (Acidi Grassi Essenziali e Infarto Miocardico) study was planned to examine the relationships between MI, whole blood fatty acids and the diet in an Italian cohort. Methods 119 Patients with a recent MI and 103 control subjects were enrolled in the study. The whole blood fatty acid composition was determined; information on anthropometrics, biochemical parameters and blood pressure values were also obtained. Diet composition was assessed using a validated food frequency questionnaire from 86 cases and 72 co…
Smoking may increase the risk of influenza hospitalization and reduce influenza vaccine effectiveness in the elderly.
2017
Background Through its effects on the immune system, smoking may facilitate influenza virus infection, its severity and its most frequent complications. The objective was to investigate the smoking history as a risk factor for influenza hospitalization and influenza vaccine effectiveness in elderly smokers/ex-smokers and non-smokers. Methods We carried out a multicenter case-control study in the 2013-2014 and 2014-2015 influenza seasons. Cases aged ≥65 years and age-, sex-matched controls were selected from 20 Spanish hospitals. We collected epidemiological variables, comorbidities, vaccination history and the smoking history. The risk of hospitalization due to smoking (current smokers and …
Strength athletes are capable to produce greater muscle activation and neural fatigue during high-intensity resistance exercise than nonathletes.
2009
Acute neuromuscular responses to maximum versus forced repetition (FR) knee extension resistance exercises (4 sets of 12 repetitions [reps] with a 2-minute recovery between the sets) were examined in 4 male strength athletes (SAs) and 4 nonathletes. Maximum repetition (MR) sets were performed to voluntary exhaustion (12 repetition maximum [RM]), whereas in the FR sets, the load was greater (8RM) and the set was continued after voluntary fatigue with 4 additional assisted reps. Maximal isometric force and electromyogram (EMG) activity of the knee extensors were measured before and after the exercise, as well as 2 recovery days after the exercise. Electromyogram activity was also measured dur…
Cognitive profile in BECTS treated with levetiracetam: A 2-year follow-up
2019
Introduction: Benign epilepsy with centrotemporal spikes (BECTS) is a common epileptic syndrome in childhood, characterized by brief and infrequent partial motor seizures, with or without generalization and mostly recurring during sleep. Because of its favorable efficacy, tolerability, and safety profile, levetiracetam (LEV) monotherapy is often administered in these patients. Long-term effects of LEV therapy and its influence on cognitive functions remain controversial.Purpose: This evaluated the changes in the cognitive profile of children with BECTS treated with LEV monotherapy for 2 years, compared with a control group of children with specific learning disabilities.Method: Our patient …
Lifetime physical activity and cancer incidence—A cohort study of male former elite athletes in Finland
2013
Abstract Objectives Physical activity has been shown to decrease the risk of certain cancers. Objective of this study was to assess the effect of physical activity on cancer incidence in former male athletes in older age. Design A cohort of 2448 elite male athletes and 1712 referents was followed-up for cancer incidence during 1986–2010 through the Finnish Cancer Registry. Methods Standardised incidence ratios were calculated with the general male population as the reference. Self-reported questionnaire-based data on covariates were used in Cox regression analyses comparing the risk of cancer in athletes and referents. Results The overall cancer incidence was lower in athletes than in the g…
Association between periodontal disease and prostate cancer: a systematic review and meta-analysis
2021
Background Periodontal disease is a chronic infectious disease caused by bacterial infection which may lead to various systematic diseases. Recently, increasing studies have explored the correlation of periodontal disease with the risk of prostate cancer. However, the findings were inconsistent. Hence, this study aims to investigate the association between periodontal disease and the risk of prostate cancer by a meta-analysis. Material and Methods PubMed, EMBASE, and Cochrane were searched for publications up to July 17, 2020. Cohort and case-control studies evaluating the risk of prostate cancer in patients with periodontal disease were included. A fixed or random-effect model was used to …
Coeliac disease: Oral ulcer prevalence, assessment of risk and association with gluten-free diet in children.
2008
Aims. Oral mucosal lesions may be markers of chronic gastrointestinal disorders, such as those causing malabsorption. Our objectives were to assess the prevalence of recurrent oral aphthous-like ulcers in coeliac disease patients living in the Mediterranean area, and to evaluate the impact of a gluten-free diet. Methods. A test group of 269 patients (age range 3-17 years) with coeliac disease confirmed both serologically and histologically was compared with a control group of 575 otherwise clinically healthy subjects for the presence, or a positive history of aphthous-like ulcers. Coeliac disease patients with aphthous-like ulcers were re-evaluated 1-year after starting a gluten-free diet. …
