Synchronous colorectal cancers (syCRCs), which present two or more lesions at diagnosis, are rare and pose a great challenge for clinical management. Although some predisposing factors associated with syCRCs have been studied with limited accession, the full repertoire of genomic events among the lesions within an individual and the causes of syCRCs remain unclear. We performed whole-exome sequencing of 40 surgical tumour samples of paired lesions from 20 patients to characterize the genetic alterations. Lesions from same patient showed distinct landscapes of somatic aberrations and shared few mutations, which suggests that they originate and develop independently although they shared the similar genetic background...

In computational neuroscience, synaptic plasticity rules are often formulated in terms of firing rates. The predominant description of in vivo neuronal activity, however, is the instantaneous rate (or spiking probability). In this article we resolve this discrepancy by showing that fluctuations of the membrane potential carry enough information to permit a precise estimate of the instantaneous rate in balanced networks. As a consequence, we find that rate based plasticity rules are not restricted to neuronal activity that is stable for hundreds of milliseconds to seconds, but can be carried over to situations in which it changes every few milliseconds...

BACKGROUND: Assessment of changes in higher levels of gait control with aging is important to better understand age-related gait instability, with the perspective to improve the screening of individuals at risk for falls. The comparison between actual Timed Up and Go test (aTUG) and its imagined version (iTUG) is a simple clinical way to assess age-related changes in gait control. The modulations of iTUG performances by body positions and motor imagery (MI) strategies with normal aging have not been evaluated yet...

Family conflict in adolescents with type 1 diabetes (T1D) has been linked to worse disease management (i.e., glycemic control, adherence to treatment regimen) and reduced quality of life. We sought to examine parental risk factors associated with increased levels of diabetes-specific family conflict and to investigate the discrepancies between parent and adolescent reports of conflict. Adolescents with T1D and their parents (N = 120 dyads) completed measures of diabetes-specific family conflict. Adolescents also reported on health-related quality of life, and parents reported on demographic information...

Background: The Oxford Cognitive Screen (OCS) was recently developed with the aim of describing the cognitive deficits after stroke. The scale consists of 10 tasks encompassing five cognitive domains: attention and executive function, language, memory, number processing, and praxis. OCS was devised to be inclusive and un-confounded by aphasia and neglect. As such, it may have a greater potential to be informative on stroke cognitive deficits of widely used instruments, such as the Mini-Mental State Examination (MMSE) or the Montreal Cognitive Assessment, which were originally devised for demented patients...

OBJECTIVE: Sometimes and when a registry is not available, influenza vaccination (IV) is based on vaccination records reported by citizens. When the opportunity of comparing both information sources exists, sometimes, discrepancies between both have been observed. The objectives of this study are: to know the IV coverage in pregnant women (both referred and recorded in the clinical history), to determine the concordance between both sources of information and to quantify the lost opportunities of IV due to errors in verbalization...

Purpose: Lumbar spinal stenosis (LSS) is a common condition in the aging population. However, limited information exists on discrepancies between LSS symptoms and imaging findings and/or prognostic factors of LSS, as well as the relationship between changes in LSS symptoms and quality of life (QoL) during the natural course of LSS. The purpose of the current study was to clarify any changes in clinically diagnosed LSS at a one-year follow-up, and identify its prognostic factors, using a community-dwelling cohort...

The use of retrospective self-reports is a major methodological concern when ascertaining the occurrence of victimization experiences, with additional concerns when assessing psychiatric patients. The test for consistency can overcome some of these concerns, increasing the confidence in the information reported. Our aim was twofold: (1) to know the consistency of victimization reports; and (2) to test the role of changes on emotional distress in predicting report discrepancies, in a sample of 34 adult psychiatric patients...

BACKGROUND: Preservation of limb function after resection of malignant bone tumors in skeletally immature children is challenging. Resection of bone sarcomas and reconstruction with an allograft in patients younger than 10 years old is one reconstructive alternative. However, long-term studies analyzing late complications and limb length discrepancy at skeletal maturity are scarce; this information would be important, because growth potential is altered in these patients owing to the loss of one physis during tumor resection...

Objectives: There have been significant advances in axial spondyloarthritis (axSpA), with implications for service delivery. We evaluated the state of axSpA rheumatology services and how people with axSpA perceive their care. Methods: An online patient survey was emailed to all members of the National Ankylosing Spondylitis Society and advertised widely via social media. Separately, a Web-based questionnaire about axSpA services was sent to rheumatologists at all 172 acute hospital trusts in the UK...

Whole genome sequencing (WGS) has become a rapid and affordable tool for public health surveillance and outbreak detection. In this study, we used the Illuminia MiSeq® to sequence 589 Campylobacter isolates obtained in 2015 from retail poultry meats as part of the National Antimicrobial Resistance Monitoring System (NARMS). WGS data were used to identify the Campylobacter species and to compare the concordance between resistance genotypes and phenotypes. WGS accurately identified 386 C. jejuni and 203 C. coli using gyrA sequence information...

A regional disparity is becoming increasingly important growth constraint. Policy makers need quantitative knowledge to design effective and targeted policies. In this paper, the regional efficiency of healthcare facilities in Slovakia is measured (2008-2015) using data envelopment analysis (DEA). The DEA is the dominant approach to assessing the efficiency of the healthcare system but also other economic areas. In this study, the window approach is introduced as an extension to the basic DEA models to evaluate healthcare technical efficiency in individual regions and quantify the basic regional disparities and discrepancies...

BACKGROUND: Traditional Chinese Medicine (TCM) is a style of traditional medicine informed by modern medicine but built on a foundation of more than 2500 years of Chinese medical practice. According to statistics, TCM accounts for approximately 14% of total adverse drug reaction (ADR) spontaneous reporting data in China. Because of the complexity of the components in TCM formula, which makes it essentially different from Western medicine, it is critical to determine whether ADR reports of TCM should be analyzed independently...

BACKGROUND: Information about the structural integrity of the corticospinal tract (CST) from diffusion-weighted imaging can improve our ability to understand motor outcomes in people with upper limb impairment after stroke, especially those with severe impairment. Yet, there is no consensus on which method of CST generation most accurately represents function and impairment in individuals with chronic stroke. NEW METHOD: The aim of the study was to compare different methods of CST reconstruction and resulting microstructural properties, as well as the relationship between these properties and motor function and impairment...

BACKGROUND: Childhood and adolescent depression is common and often persists into adulthood with negative implications for school performances, peer relationship and behavioural functioning. The Child Depression Inventory (CDI) has been used to assess depression among adolescents in many countries including Nigeria but it is uncertain if the theoretical structure of CDI appropriately fits the experiences of adolescents in Nigeria. This study assessed varying theoretical modelling structure of the CDI in a population of apparently healthy adolescents in Benue state, Nigeria...

Hepatitis C virus (HCV) genotype and subtype (1a/1b) identification is needed to tailor anti-HCV therapy. Currently available methods accurately identify the genotype and differentiate subtypes 1a from 1b. However, these assays have not been designed to identify other HCV subtypes, nor to recognize mixed genotype/subtype infections, emphasizing the need for a high-resolution system based on phylogenetic analysis of reads obtained by deep sequencing of a relevant genome region. The aim of this study was to evaluate the performance of the Sentosa SQ HCV Genotyping Assay, a novel deep sequencing-based assay targeting the HCV nonstructural 5B (NS5B) region, in clinical samples from patients with an indication for anti-HCV therapy...

This research integrates Traditional and Formal Ecological Knowledge (TEK / FEK) of a Tropical Dry Forest in central Mexico, in order to assess harvesting and conservation of the non-timber forest species. We were interested in: knowing the structure and diversity of the forest community; identifying which are the tree resources of common interest to the users through participatory workshops. A further interest was to identify those resources which are important to local people in terms of preservation; explaining the relationship of the species with some environmental factors; and visualizing which management practices endanger or facilitate the conservation of species...

Cold Heavy Oil Production with Sands (CHOPS) is a common oil extraction method in the Canadian provinces of Alberta and Saskatchewan that can result in significant methane emissions due to annular venting. Little is known about the magnitude of these emissions, nor their contributions to the regional methane budget. Here we present the results of field measurements of methane emissions from CHOPS wells and compare them to self-reported venting rates. The tracer ratio method was used not only to analyze total site emissions but at one site it was also used to locate primary emission sources and quantify their contributions to the facility-wide emission rate, revealing the annular vent to be a dominant source...
