The physician-patient relationship before cancer treatment: a prospective longitudinal study.
2003
Abstract Objectives . To evaluate quality of life before surgery for genital cancer to determine risk factors that might influence the physician–patient relationship. Methods . From 1993 until 2003, 129 women with cervical cancer entered this prospective study. Patients were contacted 1 to 5 days before surgery by a psychologist or psychotherapeutically trained physician on the surgical ward. The semistructured interview included questions on the patient's psychosocial well-being according to criteria of the biographic interview technique. The preoperative anxiety level was evaluated by the STAI and quality of life by the Cancer Rehabilitation Evaluation System (CARES) and EORTC questionnai…
Haplotypes of the caspase-1 gene, plasma caspase-1 levels, and cardiovascular risk.
2006
Caspase-1 processes the interleukin (IL)-1β and IL-18 inactive precursors to the biologically active cytokines that are known to have proatherogenic effects. The present study investigated the genetic variability of the CASP1 gene and plasma levels of caspase-1 in relation to cardiovascular risk. In Europeans, 3 tag SNPs captured 4 common haplotypes of the CASP1 gene. Among these, the A in6 allele of the G+7/in6A polymorphism was less frequent in 246 cases with myocardial infarction and a parental history of disease than in 253 controls free of familial history of disease (0.13±0.02 versus 0.20±0.02; P =0.005). However, in a larger case/control study (n=1774), these effects are borderline …
Contact dermatitis due to nickel allergy in patients suffering from non-celiac wheat sensitivity
2017
Background: Non‐celiac wheat sensitivity (NCWS) is a new clinical entity in the world of gluten‐related diseases. Nickel, the most frequent cause of contact allergy, can be found in wheat and results in systemic nickel allergy syndrome and mimics irritable bowel syndrome (IBS). Objective: To evaluate the frequency of contact dermatitis due to nickel allergy in NCWS patients diagnosed by a double‐blind placebo‐controlled(DBPC)challenge,and to identify the characteristics of NCWS patients with nickel allergy. Methods: We performed a prospective study of 60 patients (54 females, 6 males; mean age 34.1 ± 8.1 years) diagnosed with NCWS from December 2014 to November 2016; 80 age‐ and sex‐matched…
Observational Prospective Natural History of Patients with Sanfilippo Syndrome Type B
2017
To evaluate the natural course of disease progression in patients with Sanfilippo syndrome type B (mucopolysaccharidosis type IIIB), identify potential end points for future therapy trials, and characterize biomarkers related to the disease.A prospective, multicenter study was conducted. Baseline, 6-month, and 12-month assessments included neurodevelopmental status (Bayley Scales of Infant Development, Third edition), adaptive status (Vineland Adaptive Behavior Scales, Second Edition), volumetric brain magnetic resonance imaging, cerebrospinal fluid heparan sulfate, and urine glycosaminoglycan (GAG) measurements.Nineteen patients aged 1.6-31.7 years were enrolled. Over 12 months, cognition,…
Selenium status during pregnancy: Influential factors and effects on neuropsychological development among Spanish infants
2017
Selenium(Se) has been positively associated with neurodevelopment in early life. However, its margin of safety is rather narrow, and few prospective studies have evaluated its potential neurotoxic effects at intermediate levels. We aimed to explore the association between maternal Se concentrations and child neuropsychological development, including the genetic effect modification of the Se metabolizing gene INMT. Study subjects were 650 mother-child pairs from the Spanish Childhood and Environment Project (INMA, 2003-2005). Infant neuropsychological development was assessed around 12 months of age by the Bayley Scales of Infant Development. Sociodemographic and dietary characteristics were…
Serum Albumin and Future Risk of Hip, Humeral, and Wrist Fractures in Caucasian Men:New Findings from a Prospective Cohort Study
2018
<b><i>Objective:</i></b> Low serum albumin concentration is associated with poor health outcomes, but its relationship with the risk of fractures has not been reliably quantified. We aimed to assess the prospective association of serum albumin with the risk of fractures in a general population. <b><i>Subjects and Methods:</i></b> Baseline serum albumin concentrations were measured in 2,245 men aged 42–61 years in the Kuopio Ischemic Heart Disease study. Hazard ratios (HRs) (95% confidence intervals) were calculated for incident fractures. <b><i>Results:</i></b> A total of 121 fractures (hip, humeral, or wrist) were rec…
Corneal confocal scanning laser microscopy in patients with dry eye disease treated with topical cyclosporine
2017
Purpose To investigate the effect of cyclosporine on corneal ultrastructure and on major signs and symptoms of patients with dry eye disease.Patients and methods In this prospective cohort study, patients with dry eye disease were treated with a drop of cyclosporine 0.05% twice daily. Clinical evaluation was carried out at baseline and at months 1, 3, and 6. All patients completed the Ocular Surface Disease Index (OSDI) questionnaire, and tear film break-up time (BUT), fluorescein and lissamine green staining, and Schirmer test were carried out. In vivo confocal microscopy was also performed and epithelial cellular density, keratocyte activation, and subbasal plexus morphology were assessed…
Dietary inflammatory index and all-cause mortality in large cohorts: The SUN and PREDIMED studies
2019
[Background]: Inflammation is known to be related to the leading causes of death including cardiovascular disease, several types of cancer, obesity, type 2 diabetes, depression-suicide and other chronic diseases. In the context of whole dietary patterns, the Dietary Inflammatory Index (DII®) was developed to appraise the inflammatory potential of the diet. [Objective]: We prospectively assessed the association between DII scores and all-cause mortality in two large Spanish cohorts and valuated the consistency of findings across these two cohorts and results published based on other cohorts.
Aluminum Chloride versus Electrocauterization in Periapical Surgery: A Randomized Controlled Trial
2019
The aim of this study was to evaluate the efficacy of 2 hemostatic agents in periapical surgery and its relationship with patient- and tooth-dependent variables.A prospective study was designed with 2 randomized parallel groups established according to the hemostatic agent used: aluminum chloride or electrocauterization. The surgeon and 2 independent blinded observers examined the initial and final bleeding and recorded it as 0 (no hemorrhage control), 1 (slight but apparent intermittent bleeding), or 2 (complete hemorrhage control). The following patient- and tooth-dependent variables were collected: sex, age, smoking habit, plaque index, and position.Sixty patients with a periapical lesio…
Neoangiogenesis-related genes are hallmarks of fast-growing hepatocellular carcinomas and worst survival. Results from a prospective study
2016
Objective The biological heterogeneity of hepatocellular carcinoma (HCC) makes prognosis difficult. We translate the results of a genome-wide high-throughput analysis into a tool that accurately predicts at presentation tumour growth and survival of patients with HCC.Design Ultrasound surveillance identified HCC in 78 (training set) and 54 (validation set) consecutive patients with cirrhosis. Patients underwent two CT scans 6 weeks apart (no treatment in-between) to determine tumour volumes (V-0 and V-1) and calculate HCC doubling time. Baseline-paired HCC and surrounding tissue biopsies for microarray study (Agilent Whole Human Genome Oligo Microarrays) were also obtained. Predictors of su…
