An investigation of plasma interleukin-6 in sport-related concussion
2020
Background Increasing evidence suggests inflammation is an important component of concussion pathophysiology. However, its etiology, restitution, and potential clinical repercussions remain unknown. The purpose of the current study was to compare the blood concentrations of interleukin (IL) -6, a prominent inflammatory cytokine, between healthy athletes and athletes with a sport-related concussion (SRC), while addressing the potential confounds of sex, recent physical activity, and the interacting effect of concussion history. Method A prospective, observational cohort study was conducted on athletes at a single academic institute participating across 13 interuniversity sports. Follow-up of…
Risk of neuroblastoma and residential proximity to industrial and urban sites: A case-control study
2016
Background: Neuroblastoma is the most common extracranial solid tumor in children but its etiology is not clearly understood. While a small fraction of cases might be attributable to genetic factors, the role of environmental pollution factors needs to be assessed. Objectives: To ascertain the effect of residential proximity to both industrial and urban areas on neuroblastoma risk, taking into account industrial groups and toxic substances released. Methods: We conducted a population-based case-control study of neuroblastoma in Spain, including 398 incident cases gathered from the Spanish Registry of Childhood Tumors (period 1996–2011), and 2388 controls individually matched by year of birt…
Decreased FOXP3 expression in small airways of smokers with COPD
2008
CD4+CD25+ FOXP3-positive T-regulatory cells have an important role in controlling immune and inflammatory reactions. The present authors hypothesise that these cells may be involved in the pathogenesis of chronic obstructive pulmonary disease (COPD). The aim of the present study was to characterise the expression of FOXP3 in large and small airways of nonsmokers, smokers with normal lung function and COPD patients. A total of 19 nonsmokers, 20 smokers with normal lung function and 20 smokers with moderate COPD, undergoing lung resection for a solitary peripheral nonsmall cell carcinoma, were enrolled in the study. Immunohistochemical methods were used to evaluate FOXP3 expression in large a…
Blood eosinophils and treatment response in hospitalized exacerbations of chronic obstructive pulmonary disease: A case-control study
2015
Background: In outpatients with chronic obstructive pulmonary disease (COPD), blood eosinophilia is considered as a biomarker of response to systemic corticosteroid therapy. However, little is known on whether blood eosinophilia is also predictive of positive clinical outcome in severe acute exacerbations of COPD requiring hospitalization. We hypothesized that blood eosinophil-positive severe acute exacerbations of COPD differ from eosinophil-negative ones in terms of response to therapy and clinical outcomes. Methods: To test our experimental hypothesis, we retrospectively analyzed medical records of patients with COPD admitted to our ward because of severe exacerbation, over a two-year pe…
Asthma and influenza vaccination in elderly hospitalized patients: Matched case-control study in Spain
2017
Influenza infection is an exacerbating factor for asthma, and its prevention is critical in managing asthmatic patients. We investigated the effect of influenza vaccination on asthmatic and non-asthmatic patients hospitalized with laboratory-confirmed influenza in Spain.We made a matched case-control study to assess the frequency of hospitalization for influenza in people aged ≥65 years. Hospitalized patients with unplanned hospital admissions were recruited from 20 hospitals representing seven Spanish regions. Cases were defined as those hospitalized due to a laboratory-confirmed influenza infection and controls were matched by age, sex, and hospital. Data were obtained from clinical recor…
Subtherapeutic Anticoagulation Control under Treatment with Vitamin K-Antagonists—Data from a Specialized Coagulation Service
2019
AbstractIn contrast to overanticoagulation, evidence on risk factors and outcome of subtherapeutic oral anticoagulation (OAC) with vitamin K-antagonists (VKAs) under optimum care is limited. We investigated the clinical phenotype, anticoagulation control, and clinical outcome of 760 VKA patients who received OAC therapy by a specialized coagulation service in the thrombEVAL study (NCT01809015). During 281,934 treatment days, 278 patients experience ≥ 1 episode of subtherapeutic anticoagulation control and had lower quality of OAC therapy compared to 482 patients without subtherapeutic international normalized ratio: 67.6%, interquartile range (IQR) 54.9%/76.8% versus 81.0%, IQR 68.5%/90.4%;…
Maternal Supplementation with Folic Acid and Other Vitamins and Risk of Leukemia in Offspring
2014
Maternal prenatal supplementation with folic acid and other vitamins has been inconsistently associated with a reduced risk of childhood acute lymphoblastic leukemia (ALL). Little is known regarding the association with acute myeloid leukemia (AML), a rarer subtype.We obtained original data on prenatal use of folic acid and vitamins from 12 case-control studies participating in the Childhood Leukemia International Consortium (enrollment period: 1980-2012), including 6,963 cases of ALL, 585 cases of AML, and 11,635 controls. Logistic regression was used to estimate pooled odds ratios (ORs) and 95% confidence intervals (CIs), adjusted for child's age, sex, ethnicity, parental education, and s…
The REALIST (REsiduAl risk, LIpids and Standard Therapies) study: an analysis of residual risk attributable to lipid profile in acute coronary syndro…
2010
The R3i Foundation (Residual Risk Reduction Initiative), an independent, multinational and academic organization, is conducting the REALIST (Residual Risk, Lipids and Standard Therapies) study in 40 centers in different countries. This is a retrospective epidemiological study, designed to provide new data on the residual risk of major coronary events attributable to lipid abnormalities in patients receiving the current standard treatment. The initial results are expected in mid 2010, and the overall results at the end of 2010.
The relation between obesity, abdominal fat deposit and the angiotensin-converting enzyme gene I/D polymorphism and its association with coronary hea…
2004
To analyse the relation between overweight, obesity and fat distribution with I/D polymorphism of the angiotensin-converting enzyme (ACE) gene and its association with coronary heart disease (CHD). Cross-sectional, case–control study. A total of 185 cases (141 males) who had suffered at least one episode of CHD and 182 controls (127 males). Body mass index, waist circumference, blood pressure, plasma total cholesterol, triglycerides, HDL cholestrol and fasting glucose were measured with standard methods, genotyping the I/D polymorphism of ACE gene. Obesity and abdominal fat deposit are associated with CHD in women, but not independently. We have found an association between obesity and abdo…
