INTRODUCTION: Data audits within clinical settings are extensively used as a major strategy to identify errors, monitor study operations and ensure high-quality data. However, clinical trial guidelines are non-specific in regards to recommended frequency, timing and nature of data audits. The absence of a well-defined data quality definition and method to measure error undermines the reliability of data quality assessment. This review aimed to assess the variability of source data verification (SDV) auditing methods to monitor data quality in a clinical research setting...

BACKGROUND: Patients with peripheral arterial disease (PAD) often have high comorbidity burden that may complicate post-interventional course and drive increased healthcare expenditures. Racial disparity had been observed in lower extremity revascularization (LER) patterns and outcomes. In 2014, Maryland adopted an all-payer rate setting system to limit the rising hospitalization costs. This resulted in an aggregate payment system in which hospital compensation takes place as an overall per capita expenditure for hospital services...

Oligodendrocytes are fundamental for the functioning of the nervous system; they participate in several cellular processes, including axonal myelination and metabolic maintenance for astrocytes and neurons. In the mammalian nervous system, they are produced through waves of proliferation and differentiation, which occur during embryogenesis. However, oligodendrocytes and their precursors continue to be generated during adulthood from specific niches of stem cells that were not recruited during development. Deficiencies in the formation and maturation of these cells can generate pathologies mainly related to myelination...

OBJECTIVE: Genome studies have shown that the genes encoding paraoxonase 1 (PON1) and PON2 are associated with glucose metabolism. The goal of this study was to simultaneously evaluate the association between functional variants in PON1 and PON2 genes and susceptibility for type 2 diabetes (T2D) and determine whether they can affect glycemic control. METHODS: We performed a case-control study with 145 newly diagnosed patients with T2D and 148 controls. The common variants including PON1-Q192R, PON1-L55M and PON2-S311C were genotyped by PCR-based RFLP...

Gastric cancer (GC) is a highly malignant cancer with poor prognosis. Long non-coding RNA (LncRNA) may play an important role in tumor progression. Our present study aimed to explore the effect of LncRNA SOX2OT on GC progression. We observed that SOX2OT was overexpressed in GC tissues and cell lines. Overexpressed SOX2OT promoted cell proliferation and metastasis of GC cells (SGC-7901, TMK-1) and the phosphorylation of AKT2 as well, while knockdown of SOX2OT reversed these effects. Besides that, miR-194-5p was predicted to be a target of SOX2OT and decreased expression of miR-194-5p was observed in GC tissues and cell lines...

Currently, membrane-targeting small antimicrobial peptidomimetics (SAP) are important in antibiotic development because bacteria appear to develop resistance to these surface-active compounds less readily. However, the molecular membrane-targeting action of SAPs has received little attention. In this study, we investigated the effect of oligomerization of amphiphilic xanthone, a model SAP, on its antimicrobial properties against both Gram-positive and Gram-negative bacteria. First, oligomer formation by an amphiphilic xanthone, compound 2 (also coded as AM052), was investigated via solution-state nuclear magnetic resonance (NMR) spectroscopy...

Background: Treatment algorithms for neuromyelitis optica spectrum disorder (NMOSD) vary, and sparse data exist regarding the impact of initial treatments on disease course. We aimed to determine whether administration of rituximab during first hospitalization reduces 1-year readmission rates. Methods: We conducted a retrospective cohort study of subjects with NMOSD using the Pediatric Health Information System database from 2005-2015. Subjects were ages 1 to 21 years who received glucocorticoids and an ICD-9-CM code indicating neuromyelitis optica (NMO) during first hospitalization...

Target selection is the first and pivotal step in drug discovery. An incorrect choice may not manifest itself for many years after hundreds of millions of research dollars have been spent. We collected a set of 332 targets that succeeded or failed in phase III clinical trials, and explored whether Omic features describing the target genes could predict clinical success. We obtained features from the recently published comprehensive resource: Harmonizome. Nineteen features appeared to be significantly correlated with phase III clinical trial outcomes, but only 4 passed validation schemes that used bootstrapping or modified permutation tests to assess feature robustness and generalizability while accounting for target class selection bias...

Binding of odorants to olfactory receptors (ORs) elicits downstream chemical and neural signals, which are further processed to odor perception in the brain. Recently, Mainland and colleagues have measured more than 500 pairs of odorant-OR interaction by a high-throughput screening assay method, opening a new avenue to understanding the principles of human odor coding. Here, using a recently developed minimal model for OR activation kinetics, we characterize the statistics of OR activation by odorants in terms of three empirical parameters: the half-maximum effective concentration EC50, the efficacy, and the basal activity...

The study focuses on the alliance of 12 patients receiving emotion-focused therapy for social anxiety. Anxiety symptoms and patient perception of the working alliance were examined weekly. The first eight sessions of each patient were coded for within- and between-sessions alliance levels (1008 segments were coded). At the sample level, the alliance shows linear development over time but high variability between individuals. More than half the patients showed alliance development consistent with the rupture-resolution pattern...

Precision medicine is medicine optimized to the genotypic and phenotypic characteristics of an individual and, when present, his or her disease. It has a host of targets, including genes and their transcripts, proteins, and metabolites. Studying precision medicine involves a systems biology approach that integrates mathematical modeling and biology genomics, transcriptomics, proteomics, and metabolomics. Moreover, precision medicine must consider not only the relatively static genetic codes of individuals, but also the dynamic and heterogeneous genetic codes of cancers...

The importance of sharing experimental data in neuroscience grows with the amount and complexity of data acquired and various techniques used to obtain and process these data. However, the majority of experimental data, especially from individual studies of regular-sized laboratories never reach wider research community. A graphical user interface (GUI) engine called Neurovascular Network Explorer 2.0 (NNE 2.0) has been created as a tool for simple and low-cost sharing and exploring of vascular imaging data...

Although the diagnosis of posttraumatic stress disorder (PTSD) is often criticized for including symptoms that overlap with one another, only one study has explored the impact of symptom reporting. Using a clinician-rated interview for PTSD (N = 558), the current study examined overlap between PTSD criteria D1, D2, and D3 ("target D symptoms") and criterion E symptoms of similar content (i.e., E1 and E3). Furthermore, their impact on meeting criterion and disorder cutoffs was examined. Results revealed that target symptoms were endorsed in conjunction more than half the time...

Analysis of yeasts isolated from various biotopes in French Guiana led to the identification of two strains isolated from flowers and designated CLIB 1634T and CLIB 1707T . Comparison of the D1/D2 domain of the large subunit (LSU D1/D2) rRNA gene sequences of CLIB 1634T and CLIB 1707T to those in the GenBank database revealed that these strains belong to the Starmerella clade. Strain CLIB 1634T was shown to diverge from the closely related Starmerella apicola type strain CBS 2868T with a sequence divergence of 1...
