Factors associated with colorectal cancer in the context of the Mediterranean diet: a case-control study
2014
Recent evidence demonstrates that increased adherence to the Mediterranean diet (MD) may prevent colorectal cancer (CRC). The aim of this study was to evaluate the association between health-related characteristics and CRC in the context of the MD. This was a case-control study conducted on a sample of 338 consecutive patients with a first diagnosis of CRC recruited in an urban facility in the city of Catania, southern Italy, and matched with 676 apparently healthy subjects without clinical symptoms or signs of any type of cancer. Data regarding sociodemographic, clinical, and lifestyle characteristics were collected, and adherence to the Mediterranean diet pattern was assessed using the Me…
Cardiorespiratory and muscular fitness in young adult Finnish men between 2003 and 2015
2020
Introduction Physical fitness is strongly related to health and may offer valuable information about public health. We investigated trends in physical fitness, leisure-time physical activity (LTPA), and anthropometry of young healthy adult Finnish men in representative population-based samples between 2003 and 2015. Methods Three independent cross-sectional samples of 18- to 35-year-old Finnish men were assessed in 2003 (n = 889), 2008 (n = 803), and 2015 (n = 690). Cardiorespiratory (VO(2)max) and muscular fitness (1-minute sit-ups and push-ups), body mass, and height were measured. Self-reported LTPA was assessed. Results After adjusting for age, education, and smoking, cardiorespiratory …
Evaluation of 13-valent pneumococcal conjugate vaccine and concomitant meningococcal group C conjugate vaccine in healthy infants and toddlers in Spa…
2013
Abstract Background Given the concurrent administration of multiple vaccines during routine pediatric immunizations, efforts to elucidate the potential interference of any vaccine on the immune response to the concomitantly administered antigens are fundamental to prelicensure clinical research. Methods This phase 3 randomized controlled trial of 13-valent pneumococcal conjugate vaccine (PCV13) versus 7-valent PCV (PCV7) assessed immune responses of concomitantly administered meningococcal group C conjugated to diphtheria toxin cross-reactive material 197 (MnCCV-CRM 197 ) in a 2-dose infant series and 15-month toddler dose. Results 619 subjects were randomized, 315 to PCV13 and 304 to PCV7.…
Perceived stress and reference ranges of hair cortisol in healthy adolescents
2019
BackgroundChronic stress during adolescence has usually been evaluated through subjective measures, leaving aside objective measures such as hair cortisol concentrations. Therefore, the aim of this study was to provide reference ranges for hair cortisol concentrations by sex and age and to study the relationship between subjective and objective measures of stress and temporal stability.MethodsThe participants were 170 adolescents aged between 12 and 14 years (mean = 12.78 years; standard deviation = 0.71 years; 52.40% girls) who completed the Perceived Stress Scale 4 and had their hair sampled.ResultsThe results revealed hair cortisol concentrations ranging from 0.07 pg/mg to 9.54 pg/mg. Su…
An exploration of the differences in hip strength, gluteus medius activity, and trunk, pelvis, and lower-limb biomechanics during different functiona…
2020
ABSTRACT The purpose of the study was to explore differences in the coronal biomechanics of the trunk, pelvis, hip, and knee joints, and gluteus medius muscle activity (GMed) during walking and step down from two riser heights. Joint kinematics and kinetics from 20 healthy participants were recorded using a 10-camera Qualisys system and force plates, and GMed EMG was recorded using a Delsys Trigno system. Hip abductor strength was measured using a hand-held dynamometer. Pelvic obliquity and lateral trunk bending excursions were significantly higher in walking than in step-down tasks. Significantly greater knee adduction moments were seen during both step-down tasks compared to level walking…
Echocardiographic reference ranges for normal left ventricular 2D strain: results from the EACVI NORRE study
2017
International audience; Aims - To obtain the normal ranges for 2D echocardiographic (2DE) measurements of left ventricular (LV) strain from a large group of healthy volunteers accounting for age and gender. Methods and results - A total of 549 (mean age: 45.6 ± 13.3 years) healthy subjects were enrolled at 22 collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study. 2DE data sets have been analysed with a vendor-independent software package allowing homogeneous measurements irrespective of the echocardiographic equipment used to acquire the data sets. The lowest expected values of LV strains and twist calculated as ± 1.96 standard deviations from the mean…
Postural control and balance in a cohort of healthy people living in Europe: An observational study
2018
Abstract In the past 20 years, posturography has been widely used in the medical field. This observational study aimed to report the values derived from posturography of a wide set of healthy subjects from various European countries using a plantar pressure platform and a standardized method of measurement. A random cluster sampling of 914 healthy subjects aged between 7.0 and 85.99 years, stratified by age, was carried out. To provide percentile values of our cohort, data were processed to obtain 3 curves corresponding to the following percentiles: 25th, 50th, 75th, and the interquartile range. Distance-weighted least squares method was used to represent the percentile on appropriate graph…
In vitro anti-inflammatory effects of AZD8999, a novel bifunctional muscarinic acetylcholine receptor antagonist /β2-adrenoceptor agonist (MABA) comp…
2019
Recent evidence indicates that AZD8999 (LAS190792), a novel muscarinic acetylcholine receptor antagonist and β2-adrenoceptor agonist (MABA) in development for chronic respiratory diseases, induces potent and sustained relaxant effects in human bronchi by adressing both muscarinic acetylcholine receptors and β2-adrenoceptor. However, the anti-inflammatory effects of the AZD8999 monotherapy or in combination with corticosteroids are unknown. This study investigates the anti-inflammatory effects of AZD8999 in monotherapy and combined with fluticasone propionate in neutrophils from healthy and chronic obstructive pulmonary disease (COPD) patients. Peripheral blood neutrophils from healthy and C…
Corneal Biomechanics, Retinal Nerve Fiber Layer, and Optic Disc in Children
2014
Purpose. To evaluate the possible associations between corneal biomechanical parameters, optic disc morphology, and retinal nerve fiber layer (RNFL) thickness in healthy white Spanish children. Methods. This cross-sectional study included 100 myopic children and 99 emmetropic children as a control group, ranging in age from 6 to 17 years. The Ocular Response Analyzer was used to measure corneal hysteresis (CH) and corneal resistance factor. The optic disc morphology and RNFL thickness were assessed using posterior segment optical coherence tomography (Cirrus HD-OCT). The axial length was measured using an IOLMaster, whereas the central corneal thickness was measured by anterior segment opti…
Relationship between Psychophysical Measures of Retinal Ganglion Cell Density and In Vivo Measures of Cone Density in Glaucoma.
2017
Purpose Considerable between-individual variation in retinal ganglion cell (RGC) density exists in healthy individuals, making identification of change from normal to glaucoma difficult. In ascertaining local cone-to-RGC density ratios in healthy individuals, we wished to investigate the usefulness of objective cone density estimates as a surrogate of baseline RGC density in glaucoma patients, and thus a more efficient way of identifying early changes. Design Exploratory cohort study. Participants Twenty glaucoma patients (60% women) with a median age of 54 years and mean deviation (MD) in the visual field of –5 dB and 20 healthy controls (70% women) with a median age of 57 years and a mean…
