BACKGROUND: To improve individuals' participation in cardiovascular disease (CVD) screening, it is necessary to understand factors that influence their intention to undergo health checks. This study aimed to develop and validate an instrument that assess determinants that influence individuals' intention to undergo CVD health checks. METHODS: The concepts and items were developed based on findings from our prior exploratory qualitative study on factors influencing individuals' intention to undergo CVD health checks...

A sensitive, specific, selective and rapid LC-ESI-MS/MS method has been developed and validated for the quantification of defactinib in mice plasma using (13)C3,(15)N-tofacitinib as an internal standard (I.S.). Sample preparation was accomplished through a liquid-liquid extraction process. Baseline chromatographic resolution of defactinib and the I.S. was achieved on an Atlantis dC18 column using an isocratic mobile phase comprising 0.2% formic acid in water and acetonitrile (25:75, v/v) delivered at a flow rate of 0...

OBJECTIVE: The aim of the present study was to create a translated version of the Pediatric Quality of Life Inventory™ 3.0 Diabetes Module (PedsQL™ 3.0 Diabetes Module) in Brazilian Portuguese that was conceptually equivalent to the original American English version and to linguistically validate it in a Brazilian pediatric population with type 1 diabetes mellitus and their parents or caregivers. METHODS: The instrument was translated, back-translated, and then administered to 83 children/adolescents (5-18 years) with type 1 diabetes mellitus and their family members and to 25 parents/caregivers of patients aged between 2 and 4 years...

Joel R Anderson
This paper reports the initial psychometric properties for the recently developed prejudice against asylum seekers scale (PAAS) - a new measure of the classical and conditional components of negative attitudes towards asylum seekers. Across three studies the initial psychometric evidence is presented: An exploratory factor analysis suggested that the 16 items of the PAAS accurately factor onto the two hypothesized subscales (Study 1), which was ratified using a confirmatory factor analysis (Study 2). The presented reliability estimates (internal consistency: Studies 1-3; test-retest reliability: Study 3) verified the stability of the measure...

Objective: In order to find low abundant proteins secretome and tumor tissue proteome data have been explored in the last few years for the diagnosis of colorectal cancer (CRC). In this review we aim to summarize the results of studies evaluating markers derived from the secretome and tumor proteome for blood based detection of colorectal cancer. Methods: Observing the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines PubMed and Web of Science databases were searched systematically for relevant studies published up to 18 July 2017...

The Diagnostic and Statistical Manual of Mental Disorders (5th edition) Alcohol Use Disorder (DSM-5 AUD) criteria have been modified to reflect a single, continuous disorder. It is critical that we develop brief assessment measures that can accurately assess for DSM-5 AUD criteria in college students to assist in screening, referral, and brief intervention services implemented on college campuses. The present study sought to develop and assess for the psychometric properties of a brief 13-item measure designed to capture the full spectrum of the DSM-5 AUD criteria in a sample of college students...

Tubuloside B, a novel neuroprotective phenylethanoid, is a major active constituent of Cistanche tubulosa and Cistanche deserticola. A specific and sensitive liquid chromatography tandem mass spectrometry (LC-MS/MS) method has been developed and validated for the quantification of tubuloside B in rat plasma. Sample preparation was conducted through a protein-precipitation extraction with methanol using tubuloside A as internal standard (IS). Chromatographic separation was achieved by using a Capcell Pak C18 column (2...

INTRODUCTION: Mean platelet volume (MPV) assists the differential diagnosis of inherited thrombocytopenia (IT) but lacks standardisation and varies between automated analysers. Classification of IT based on mean platelet diameter (MPD) has been proposed by an international collaborative study but has not been validated. METHODS: To assess the applicability of MPD to classify forms of IT, digital images of blood films from patients with established genetic causes for IT were generated, and the MPD measured (ZEISS Axio-scanner and Image J software) by a blinded reviewer...

WHAT IS KNOWN AND OBJECTIVE: The French Society of Clinical Pharmacy (SFPC) asked a group of experts to adapt the SFPC hospital pharmacists' interventions reporting tool for use in community pharmacy practice. This study aimed to develop and validate a tool for the routine reporting of pharmacists' interventions in French community settings. METHODS: Two groups of community pharmacists coded reports of 60 typical pharmacists' interventions. One group was "experts" (n = 4) who had participated in the development of the tool (internal validation) and the other were "external" community pharmacists (n = 6), naïve to the tool (external validation)...

In 2009 the diagnosis chronic pain disorder with somatic and psychological factors (F45.41) was integrated into the German version of the International Classification of Diseases, version 10 (ICD-10-GM). In 2010 Paul Nilges and Winfried Rief published operationalization criteria for this diagnosis. In the present publication the ad hoc commission on multimodal interdisciplinary pain therapy of the German Pain Society now presents a formula for a clear validation of these operationalization criteria of the ICD code F45...

Background Major Depressive Disorder (MDD) is a common comorbidity that significantly affects the quality of life and disease outcomes in Parkinson's disease (PD) patients. No studies have been conducted to our knowledge to address the health care utilization and its outcomes in these patients. The aim of this study is to analyze and discern the differences in the hospitalization outcomes, comorbid conditions, and utilization of procedures in PD patients versus patients with comorbid MDD. Methods We used the Nationwide Inpatient Sample from the Healthcare Cost and Utilization Project from year's 2010-2014...

Background: In low- and middle-income countries such as India, where health systems are weak, the number of available Critical Care Unit (Intensive Care Unit [ICU]) beds is expected to be low. There is no study from the Indian subcontinent that has reported the characteristics and distribution of existing ICUs. We performed this study to understand the characteristics and distribution of ICUs in Madhya Pradesh (MP) state of Central India. We also aimed to develop a consensus scoring system and internally validate it to define levels of care and to improve health system planning and to strengthen referral networks in the state...
