Astigmatism in infancy and childhood.
2000
ABSTRACT Purpose: To evaluate the prevalence of astigmatism In infancy and childhood In a Spanish population. Methods: A total of 478 children with astigmatism from Valencia Province, Spain were examined. The patients, ranging in age from 2-1 2 years, were classified into groups according to age. Astigmatism error and axis orientation were determined using noncyclopeglc retlnoscopy over each eye. Results: The overall prevalence of astigmatism (5=1.00 diopter of cylinder) decreased In relation to increasing age from 44.3% to 5.2%. The prevalence of against-the-rule astigmatism decreased from 61.5% (at 2 years) to 33.4% (at 12 years), with-the-rule astigmatism increased In prevalence from 23.…
Prevalence and risk factors of post-polio syndrome in a cohort of polio survivors.
2005
Abstract Objective To investigate frequency and associated factors of post polio syndrome (PPS) in an Italian cohort of people with prior poliomyelitis. Methods We screened subjects admitted for poliomyelitis at the paediatric hospital of the University of Palermo during the time frame 1945–1960. Patients who developed PPS were identified through a structured questionnaire and a neurologic examination. PPS diagnosis was made according to specified diagnostic criteria. Frequency of PPS was calculated in the selected cohort of polio survivors. The association with the investigated risk factors (sex, age at onset of polio, extension and severity of polio, education, associated diseases, cigare…
Gender-related differences in serum uric acid in treated hypertensive patients from central and east European countries: findings from the Blood Pres…
2019
OBJECTIVE: Hyperuricemia has been associated with high blood pressure (BP) values, diabetes mellitus, metabolic syndrome and chronic kidney disease (CKD). In the present study, we assessed the gender-related relationships between serum uric acid (SUA) and cardionephrometabolic variables in central and east European hypertensive patients. METHODS: A total of 3206 treated hypertensive patients with available SUA levels from the BP-CARE study was analyzed. Correlations among SUA, BP values, BP control, diabetes mellitus, metabolic syndrome and CKD were performed according to gender. RESULTS: Twenty-five percent of the whole population showed hyperuricemia (28% in women and 23% in men). These p…
Fatores que influenciam a ocorrência de otite media entre crianças sicilianas com infecções de vias aéreas superiores
2016
ABSTRACT INTRODUCTION: Upper respiratory tract infection is a nonspecific term used to describe an acute infection involving the nose, paranasal sinuses, pharynx and larynx. Upper respiratory tract infections in children are often associated with Eustachian tube dysfunction and complicated by otitis media, an inflammatory process within the middle ear. Environmental, epidemiologic and familial risk factors for otitis media (such as sex, socioeconomic and educational factors, smoke exposure, allergy or duration of breastfeeding) have been previously reported, but actually no data about their diffusion among Sicilian children with upper respiratory tract infections are available. OBJECTIVE: T…
Different Prevalence of Alarm, Dyspeptic and Reflux Symptoms in Patients with Cardia and Non-cardia Gastric Cancer.
2021
Background and Aims: Symptoms of patients with gastric cancer (GC) are often unspecific and differences in symptoms between patients with cardia and non-cardia GC have been poorly investigated. We aimed to characterize symptoms of patients with cardia and non-cardia GC.
 Methods: Patients with cardia (Siewert type II and III) and non-cardia GC were recruited in the German multicenter cohort of the Gastric Cancer Research (staR) study between 2013 and 2017. Alarm, dyspeptic and reflux symptoms at the time of presentation were documented using a self-administered questionnaire.
 Results: A completed self-administered questionnaire was available for 568/759 recruited patients (132 ca…
Pressure ulcers’ incidence, preventive measures, and risk factors in neonatal intensive care and intermediate care units
2018
Epidemiological studies on pressure ulcers (PUs) in hospitalised infants are scarce. Spain lacks comprehensive research studies providing data on the prevalence or incidence in this population. This work was developed to determine the incidence of PUs in hospitalised infants admitted to intensive and intermediate care units, along with relevant risk factors and preventive measures. A prospective study appraising the incidence of PUs in infants was performed. The risk factors and preventive measures were evaluated using a multivariate logistic regression model. A sample of 268 infants was included. The cumulative incidence of PUs was 12.70% (95% confidence interval, CI(95%) = [8.95%‐17.28%])…
Association of a Mineralocorticoid Receptor Gene Polymorphism With Hypertension in a Spanish Population
2009
BACKGROUND To assess the association of polymorphisms and haplotypes of the mineralocorticoid receptor (MR) (NR3C2) gene to the risk of essential hypertension (HTN) in a Spanish population. METHODS This is a population-based study which included 1,502 subjects (748 women) >18 years old. Twenty-four polymorphisms of NR3C2 gene were analyzed by using SNPlex (Genotyping System based on OLA/PCR technology). RESULTS Alleles of the single-nucleotide polymorphism (SNP) rs5522 were significantly associated with the risk of HTN, both in the recessive and codominant models adjusted by age, gender, and body mass index (BMI). Genotype GG of the rs5522 showed to be protective against HTN odds ratio (OR)…
Frailty Is Associated with Oxidative Stress in Older Patients with Type 2 Diabetes
2021
Aging has increased the prevalence of frailty, and type 2 diabetes (T2D) has also increased in prevalence. Diabetes and oxidative stress (OS) have been shown to be related to frailty. However, the exact mechanism by which it occurs is not fully known. Our aim was to analyze body composition in community-dwelling older diabetic people treated in our center and to evaluate the possible relation between OS, frailty, and body composition. We included 100 adults older than 65 years with T2D. We found that 15% were frail and 57% were prefrail. The patients included in the nonrobust group showed increased levels of OS. Our study shows that the presence of T2D in the geriatric population is associa…
Complications of trans-anastomotic externalised stents in open pyeloplasty: influence of the method of placement, the duration of stenting, and the a…
2010
To assess the influence of the method for stent placement, the duration of stenting, and the presence of bladder drainage on the complication rate of open pyeloplasty. Patients and methods: Complications were, retrospectively, compared in 228 consecutive open pyeloplasties performed at institution A using a trans-pyelostomic 6-Fr splint/stent for 5 days and no bladder drainage, and 150 consecutive open pyeloplasties performed at institution B using a trans-nephrostomic 6-Fr splint/stent for 9 days plus bladder drainage. Results: Median age at surgery was comparable between groups. The overall complication rate was 13% and was comparable at the two institutions, but for the presence of perio…
Metabolic syndrome, organ damage and cardiovascular disease in treated hypertensive patients. The ERIC‐HTA study
2007
The aim of this study is to assess the relationship among metabolic syndrome (MS), target organ damage (TOD) and established cardiovascular disease (CVD) in non-diabetic hypertensive elderly patients. ERIC-HTA is cross-sectional, multicentre study carried out in primary care, on hypertensive patients aged 55 or older. MS was defined by the NCEP-ATP III criteria, using body mass index (28.8 kg/m(2)) instead of abdominal perimeter. In 8331 non-diabetic hypertensive patients (3663 men and 4668 women, mean age 67.7 years), the prevalence of MS was 32.6% (men: 29.0%; women: 36.8%). A linear association was observed between a greater number of components of MS and a greater prevalence of left ven…
