Vaccines are among the most efficacious and cost-effective tools for reducing morbidity and mortality caused by infectious diseases. The vaccine investigation and online information network (VIOLIN) is a web-based central resource, allowing easy curation, comparison and analysis of vaccine-related research data across…

OBJECTIVE: Dissemination of research findings is central to research integrity and promoting discussion of new knowledge and its potential for translation into practice and policy. We investigated the frequency and format of dissemination to trial participants and patient groups. DESIGN: Survey of authors of clinical…

Rosette-forming glioneuronal tumor (RGNT) of the fourth ventricle is a mixed glio-neuronal neoplasm recently codified by the World Health Organization WHO Classification of Central Nervous System (CNS) Tumors (2007). To date, 43 cases have been described in the literature; most occurring in the fourth ventricle region.…

The COVID-19 outbreak has made funders, researchers and publishers agree to have research publications, as well as other research outputs, such as data, become openly available. In this extraordinary research context of the SARS CoV-2 pandemic, publishers are announcing that their coronavirus-related articles will be m…

A significant proportion of the outcomes reported in trials assessing venous thromboembolism (VTE) prophylaxis in medical patients are related to asymptomatic events found on routine imaging studies. The implications of these events are controversial. Moreover, such trials did not always reflect the patient mix in toda…

Computer-based resources are central to much, if not most, biological and medical research. However, while there is an ever expanding choice of bioinformatics resources to use, described within the biomedical literature, little work to date has provided an evaluation of the full range of availability or levels of usage…

OBJECT: Given the feasibility of curative surgical and endovascular therapy for cerebral dural arteriovenous fistulas (DAVFs), there is a relative paucity of radiosurgical series for these lesions as compared with their arteriovenous malformation counterparts. METHODS: The authors reviewed records of 56 patients with…

OBJECTIVE: To evaluate the safety and efficacy of totally endoscopic repair of atrial septal defect (ASD). METHODS: A review of the literature was conducted. Studies were obtained from the following sources: MEDLINE, EMBASE, Web of Science and CENTRAL Library. Inclusion criteria were: (1) randomised controlled trials,…

BACKGROUND: Globally, 36% of deaths among children can be attributed to environmental factors. However, no comprehensive list of environmental exposures exists. We seek to address this gap by developing a literature-mining algorithm to catalog prenatal environmental exposures. METHODS: We designed a framework called.…

Collecting and analysing all available literature before starting an animal experiment is important and it is indispensable when writing a systematic review (SR) of animal research. Writing such review prevents unnecessary duplication of animal studies and thus unnecessary animal use (Reduction). One of the factors cur…

OBJECTIVE: To systematically and critically analyse and summarise the published evidence for the rational choice of pharmacologic treatment of the neonatal abstinence syndrome (NAS), a frequently observed condition in neonates born to mothers who are dependent on physically addicting drugs. DESIGN: Studies comparing d…

BACKGROUND: This article provides an overview of the first BIOASQ challenge, a competition on large-scale biomedical semantic indexing and question answering (QA), which took place between March and September 2013. BIOASQ assesses the ability of systems to semantically index very large numbers of biomedical scientific…

Research results are primarily published in scientific literature and curation efforts cannot keep up with the rapid growth of published literature. The plethora of knowledge remains hidden in large text repositories like MEDLINE. Consequently, life scientists have to spend a great amount of time searching for specific…

AIMS: Serotonin transporter (5-HTT) plays a central role in the regulation of serotonin (5-hydroxytryptamine [5-HT]) synaptic function. Disturbances in 5-HT transmission are the most frequently reported neurobiological substrates of suicidal behavior. Emerging evidence has shown that the common polymorphisms in the 5-H…

Recently, advanced text-mining techniques have been shown to speed up manual data curation by providing human annotators with automated pre-annotations generated by rules or machine learning models. Due to the limited training data available, however, current annotation systems primarily focus only on common concept ty…

PolySearch2 (http://polysearch.ca) is an online text-mining system for identifying relationships between biomedical entities such as human diseases, genes, SNPs, proteins, drugs, metabolites, toxins, metabolic pathways, organs, tissues, subcellular organelles, positive health effects, negative health effects, drug acti…

In addition to maintaining the GenBank nucleic acid sequence database, the National Center for Biotechnology Information (NCBI) provides analysis and retrieval resources for the data in GenBank and other biological data made available through the NCBI web site. NCBI resources include Entrez, the Entrez Programming Util…

BACKGROUND: Burning mouth syndrome (BMS) and occlusal dysesthesia (OD) are chronic oral sensory disorders that present without evident local pathology yet frequently cause substantial diagnostic and therapeutic challenges in oral medicine practice. Although both conditions may clinically overlap, their mechanistic rela…
