Influence of plasma processing on recovery and analysis of circulating nucleic acids.
(2013)
Circulating nucleic acids (CNAs) are under investigation as a liquid biopsy in cancer. However there is wide variation in blood processing and methods for isolation of circulating free DNA (cfDNA) and microRNAs (miRNAs). ...
Radiographic endophenotyping in hip osteoarthritis improves the precision of genetic association analysis.
(2017-07)
OBJECTIVE: Osteoarthritis (OA) has a strong genetic component but the success of previous genome-wide association studies (GWAS) has been restricted due to insufficient sample sizes and phenotype heterogeneity. Our aim was ...
Atypical risk factor profile and excellent long-term outcomes of young patients treated with primary percutaneous coronary intervention for ST-elevation myocardial infarction.
(2016-02)
INTRODUCTION: Several studies have examined the relationship between age and clinical outcomes in patients with ST-elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PPCI). The ...
Genetically Predicted Body Mass Index and Breast Cancer Risk: Mendelian Randomization Analyses of Data from 145,000 Women of European Descent.
(2016-08)
BACKGROUND: Observational epidemiological studies have shown that high body mass index (BMI) is associated with a reduced risk of breast cancer in premenopausal women but an increased risk in postmenopausal women. It is ...
Fracture Risk in Relation to Serum 25-Hydroxyvitamin D and Physical Activity: Results from the EPIC-Norfolk Cohort Study.
(2016)
Vitamin D deficiency and physical inactivity have been associated with bone loss and fractures, but their combined effect has scarcely been studied either in younger or older adults. Therefore, we aimed to assess the ...
Detection of HER2 amplification in circulating free DNA in patients with breast cancer.
(2011-04-12)
BACKGROUND: Human epidermal growth factor receptor 2 (HER2) is amplified and overexpressed in 20-25% of breast cancers. This study investigated circulating free DNA (cfDNA) for detection of HER2 gene amplification in ...
Whole genome sequence analysis suggests intratumoral heterogeneity in dissemination of breast cancer to lymph nodes.
(2014)
BACKGROUND: Intratumoral heterogeneity may help drive resistance to targeted therapies in cancer. In breast cancer, the presence of nodal metastases is a key indicator of poorer overall survival. The aim of this study was ...
Mortality of emergency general surgical patients and associations with hospital structures and processes.
(2016-01)
BACKGROUND: Variations in patient outcomes between providers have been described for emergency admissions, including general surgery. The aim of this study was to investigate whether differences in modifiable hospital ...
Prevalence of Diabetes on Santa Cruz Island in Galapagos Archipelago.
(2015-06-18)
This was an observational study offering a screening program for diabetes in a health clinic in Puerto Ayora town on Santa Cruz Island to determine the prevalence of this disorder and identify those at risk. A 1-month ...
Evaluation of splenic switch off in a tertiary imaging centre: validation and assessment of utility.
(2017-11-01)
Aims: Adenosine can induce splenic vasoconstriction (splenic switch-off, SSO). In this study, we aim to evaluate the utility of identifying a lack of SSO for detecting false-negative adenosine stress perfusion cardiac ...
