Cancer is responsible for millions of deaths worldwide, but most base diseases may be cured if detected early. Screening tests may be used to identify early-stage malignant neoplasms. However, the major screening tool for prostate cancer, the prostate-specific antigen test, has unsuitable sensitivity. Since cancer cells may affect the pattern of consumption and excretion of nucleosides, such biomolecules are putative biomarkers that can be used for diagnosis and treatment evaluation. Using a previously validated method for the analysis of nucleosides in blood serum by capillary electrophoresis with UV-vis spectroscopy detection, we investigated 60 samples from healthy individuals and 42 samples from prostate cancer patients...

Chlorinated polycyclic aromatic hydrocarbons (ClPAHs), including polychlorinated naphthalenes (PCNs), are hazardous and widespread in the environment, but studies of these substances in the wastewater environment are lacking. In this study, five typical PCNs and five typical ClPAHs (other than PCNs) were simultaneously detected along with their parent polycyclic aromatic hydrocarbons in wastewater samples. All these compounds could be analyzed by gas chromatography- electron ionization mass spectrometry in selected ion monitoring mode and separated on a DB-17ms column...

Dissemination of research studies is important for research ideas to be transformed from initial abstracts to full publications. Analyses of the scientific impact and publication record of the Canadian Rheumatology Association (CRA) Annual meeting have not been previously described. This study determines the publication rate of abstracts presented at the CRA Annual Meetings 2005-2013 to full-text journal articles and the factors associated with publication. Program records of previous CRA meetings from 2005 to 2013 were obtained...

Many different text features influence text readability and content comprehension. Negation is commonly suggested as one such feature, but few general-purpose tools exist to discover negation and studies of the impact of negation on text readability are rare. In this paper, we introduce a new negation parser (NegAIT) for detecting morphological, sentential, and double negation. We evaluated the parser using a human annotated gold standard containing 500 Wikipedia sentences and achieved 95%, 89% and 67% precision with 100%, 80%, and 67% recall, respectively...

BACKGROUND: In-hospital placement of intrauterine devices (IUD) and contraceptive implants following vaginal and cesarean delivery is increasingly popular and responds to maternal motivation for highly effective postpartum contraception. Immediate postpartum IUD insertion is associated with higher expulsion than interval placement, but emerging evidence suggests that the LNG IUD may have a higher expulsion rate than the Cu IUD. OBJECTIVE: This study evaluated in-hospital provision, expulsion and six month continuation of immediate postpartum copper T380 IUDs (Cu IUD), levonorgestrel (LNG) IUDs, and contraceptive implants...

OBJECTIVE: Direct revascularization (DR), according to the angiosome concept, provides direct blood flow to the site of tissue loss in patients with critical limb ischemia (CLI). DR may lead to improved outcomes; however, evidence for this is controversial. This systematic review and meta-analysis investigated the outcomes of surgical and endovascular DR compared with indirect revascularization (IR) in patients with CLI. METHODS: A systematic review was undertaken using the Cochrane Collaboration specified tool, and a meta-analysis was done according to the MOOSE (Meta-analysis of Observational Studies in Epidemiology) criteria...

Paralytic polio once afflicted almost half a million children each year. The attenuated oral polio vaccine (OPV) has enabled world-wide vaccination efforts, which resulted in nearly complete control of the disease. However, poliovirus eradication is hampered globally by epidemics of vaccine-derived polio. Here, we describe a combined theoretical and experimental strategy that describes the molecular events leading from OPV to virulent strains. We discover that similar evolutionary events occur in most epidemics...

Proteinuria is a distinguishing feature in primary and secondary forms of chronic glomerulonephritis, which contribute to no more than the 20% of the end-stage kidney disease (ESKD) population. The contribution of non-proteinuric nephropathies to the global ESKD burden is still poorly focused and scarce research efforts are dedicated to the elucidation of risk factors and mechanistic pathways triggering ESKD in these diseases. We abstracted information on proteinuria in the main renal diseases other than glomerulonephritides that may evolve into ESKD...

The effectiveness of biologic therapies now means that remission or low disease activity are realistic targets for treatment. However, after achieving remission/low disease activity, the next steps remain unclear. The aim of this publication was to conduct a broad systematic literature review to evaluate dosing down of biologics. After screening papers and abstracts for relevance and application of inclusion/exclusion criteria, a structured extraction process was used to collect information on the included studies...

BACKGROUND: Of all the postsurgical pain conditions, thoracotomy pain poses a particular therapeutic challenge in terms of its prevalence, severity, and ensuing postoperative morbidity. Multiple pain generators contribute to the severity of post-thoracotomy pain, and therefore a multimodal analgesic therapy is considered to be a necessary strategy. Along with opioids, thoracic epidural analgesia, and paravertebral blocks, N-Methyl-D-Aspartate (NMDA) receptor antagonists such as ketamine have been used as adjuvants to improve analgesia...

BACKGROUND AND PURPOSE: Studies have shown a reduction in time-to-CT and improved process measures when EMS personnel notify the ED of a "stroke alert" from the field. However, there are few data on the accuracy of these EMS stroke alerts. The goal of this study was to examine diagnostic test performance of EMS and ED stroke alerts and related process measures. METHODS: The EMS and ED records of all stroke alerts in a large tertiary ED from August 2013-January 2014 were examined and data abstracted by one trained investigator, with data accuracy confirmed by a second investigator for 15% of cases...

Background: orthostatic hypotension (OH) is one out of many risk factors believed to contribute to an increased fall risk in elderly subjects but it is unclear whether an independent association between OH and falling exists. Objectives: to perform an individual patient data (IPD) meta-analysis of prospective observational studies investigating the relationship between OH and falling. Design: MEDLINE, EMBASE, the Cochrane Library and the abstracts of annual meetings of selected hypertension societies were searched...

The ability to mentally represent future events is a significant human psychological achievement. A challenge that people encounter is that they often lack detailed specifics about distant relative to near future events. Construal level theory (Liberman & Trope, 2014) proposes that people represent distant future events by their abstract and essential features - a process referred to as high-level construal. As events become temporally proximal, people represent events by their increasingly available and reliable concrete and idiosyncratic features - a process referred to as low-level construal...

OBJECTIVE: Selective serotonin reuptake inhibitor/serotonin-norepinephrine reuptake inhibitors are among the most commonly prescribed drugs in patients admitted to the ICU. Our objective was to systematically review available literature for evidence of benefit or harm in ICU patients resulting from chronic effects, continued use, or withdrawal. DATA SOURCES: Medline, Embase, and Cochrane Central Register of Controlled Trials (1990 to November 2014). STUDY SELECTION: We searched for studies of ICU patients with recorded selective serotonin reuptake inhibitor/serotonin-norepinephrine reuptake inhibitor prescription before or during admission, and reporting morbidity, mortality, adverse events, and resource measures like ICU length of stay...

PURPOSE OF REVIEW: Until recently, management options in congenital cytomegalovirus (cCMV) infection have been either conservative or termination of pregnancy. However, medical therapies aimed at reducing the risk of infection and/or its severity have recently been investigated. RECENT FINDINGS: In a phase 2 open label, nonrandomized trial, valaciclovir (ValACV) was given to women carrying a CMV-infected fetus. ValACV was associated with a greater proportion of asymptomatic neonates when compared with a historical cohort (82 vs...
