Jelte M Wicherts, Elise A V Crompvoets
The syntax or codes used to fit Structural Equation Models (SEMs) convey valuable information on model specifications and the manner in which SEMs are estimated. We requested SEM syntaxes from a random sample of 229 articles (published in 1998-2013) that ran SEMs using LISREL, AMOS, or Mplus. After exchanging over 500 emails, we ended up obtaining a meagre 57 syntaxes used in these articles (24.9% of syntaxes we requested). Results considering the 129 (corresponding) authors who replied to our request showed that the odds of the syntax being lost increased by 21% per year passed since publication of the article, while the odds of actually obtaining a syntax dropped by 13% per year...

Two clinical vignettes demonstrate a methodological approach that guides the analyst's attention to metaphors and surfaces that are the focus of different theories. Clinically, the use of different theories expands the metaphorical language with which the analyst tries to make contact with the patient's unconscious life. Metaphorical expressions may be said to relate to each other as the syntax of unconscious fantasy (Arlow 1979). The unconscious fantasy itself represents a metaphorical construction of childhood experience that has persisted, dynamically expressive and emergent into adult life...

OBJECTIVES: Clinical prediction models that support treatment decisions are usually evaluated for their ability to predict the risk of an outcome rather than treatment benefit - the difference between outcome risk with versus without therapy. We aimed to define performance metrics for a model's ability to predict treatment benefit. STUDY DESIGN AND SETTING: We analyzed data of the Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) trial, and of 3 recombinant tissue plasminogen activator trials...

BACKGROUND AND AIMS: Endothelial dysfunction and coronary artery calcification (CAC) may represent two distinct and separate processes in the development of coronary atherosclerosis. However, the interaction between these factors in determining the development of coronary artery disease (CAD) is uncertain. METHODS: Brachial artery flow-mediated dilatation (FMD) was measured by high-resolution ultrasound before coronary angiography, in 156 patients undergoing coronary CT angiography on suspicion of CAD (M/F 100/56, age 67 ± 11yrs)...

BACKGROUND: There are few reports demonstrating a relationship between presystolic wave (PSW) and left ventricular function. The aim of the present study was to investigate the associations between PSW and angiographic and echocardiographic characteristics of patients with acute myocardial infarction (AMI). METHODS: We studied 348 consecutive patients with AMI. Pulsed Doppler-echocardiography was used to assess the both diastolic functions and presence of PSW from left ventricular outflow tract...

Purpose: Annually, nearly 700,000 U.S. children and adolescents experience a traumatic brain injury (TBI). Many of them struggle academically, despite failing to qualify for special education services because their cognitive communication impairments are subtle. Method: In this exploratory study, five adolescents with TBI provided verbal summaries of two expository lectures (compare-contrast, cause-effect) and participated in cognitive and expressive syntax testing...

An increased systemic and local inflammation plays a key role in the pathophysiology of acute coronary syndrome (ACS). This review will discuss the role of hematological indices: white blood cells (WBC), neutrophil to lymphocyte ratio (NLR), red cell distribution width (RDW), and platelet indices, that is, platelet to lymphocyte ratio (PLR), mean platelet volume (MPV), and platelet distribution width (PDW) in the case of ACS. In recent years, a strong interest has been drawn to these indices, given that they may provide independent information on pathophysiology, risk stratification, and optimal management...

BACKGROUND: We aimed to evaluate possible association between QRS duration (QRSD), R wave peak time (RWPT), and coronary artery disease severity identified using the SYNTAX score (SS) in patients with unstable angina pectoris (USAP) or non-ST segment elevation myocardial infarction (NSTEMI). METHOD: A total of 176 USAP/NSTEMI patients were enrolled in the study. RESULTS: The high SS group (>22, n:45) patients had a higher prevalence of diabetes mellitus (DM); presence of ST segment depression ≥0...

The impact of the severity of coronary artery disease (CAD) and left ventricular ejection fraction (LVEF) on the prognosis of patients with peripheral artery disease (PAD) has not been systematically studied. We retrospectively analysed 622 patients with PAD (intermittent claudication (IC): n = 446; critical limb ischaemia (CLI): n = 176). The association of SYNTAX score and LVEF with mortality was analysed using the Cox proportional hazard model. In patients with IC, a high SYNTAX score was significantly associated with mortality, whereas reduced LVEF was significantly associated with mortality in patients with CLI...

This brief research report examines brain-behavioral relationships specific to levels of language in the complex reading brain. The first specific aim was to examine prior findings for significant fMRI connectivity from four seeds (left precuneus, left occipital temporal, left supramarginal, left inferior frontal) for each of four levels of language-subword, word (word-specific spelling or affixed words), syntax (with and without homonym foils or affix foils), and multi-sentence text to identify significant fMRI connectivity (a) unique to the lower level of language when compared to the immediately higher adjacent level of language across subword-word, word-syntax, and syntax-text comparisons; and (b) involving a brain region associated with executive functions...

Authorship attribution is to identify the most likely author of a given sample among a set of candidate known authors. It can be not only applied to discover the original author of plain text, such as novels, blogs, emails, posts etc., but also used to identify source code programmers. Authorship attribution of source code is required in diverse applications, ranging from malicious code tracking to solving authorship dispute or software plagiarism detection. This paper aims to propose a new method to identify the programmer of Java source code samples with a higher accuracy...

Generative artificial intelligence models present a fresh approach to chemogenomics and de novo drug design, as they provide researchers with the ability to narrow down their search of the chemical space and focus on regions of interest. We present a method for molecular de novo design that utilizes generative recurrent neural networks (RNN) containing long short-term memory (LSTM) cells. This computational model captured the syntax of molecular representation in terms of SMILES strings with close to perfect accuracy...

While acquiring motor skills, animals transform their plastic motor sequences to match desired targets. However, because both the structure and temporal position of individual gestures are adjustable, the number of possible motor transformations increases exponentially with sequence length. Identifying the optimal transformation towards a given target is therefore a computationally intractable problem. Here we show an evolutionary workaround for reducing the computational complexity of song learning in zebra finches...

Grammatical markers are not uniformly impaired across speakers of different languages, even when speakers share a diagnosis and the marker in question is grammaticalized in a similar way in these languages. The aim of this work is to demarcate, from a cross-linguistic perspective, the linguistic phenotype of three genetically heterogeneous developmental disorders: specific language impairment, Down syndrome, and autism spectrum disorder. After a systematic review of linguistic profiles targeting mainly English-, Greek-, Catalan-, and Spanish-speaking populations with developmental disorders (n = 880), shared loci of impairment are identified and certain domains of grammar are shown to be more vulnerable than others...

Ethical, practical, and medical challenges affect decisions about left ventricular assist device (LVAD) implantation. The informed consent document (IC-Doc) is integral to the decision-making process and structures informed consent conversations. The objective of this study was to analyze IC-Docs to identify the information patients and their families receive about LVAD implantation to create a model IC-Doc. We requested IC-Doc for LVAD implantation from LVAD programs in the United States. We analyzed them in three areas: medical and technical content, patient knowledge gaps, and syntax...

OBJECTIVE: To evaluate and validate the time of completion and results of a new method of searching for systematic reviews, the exhaustive search method (ESM), using a pragmatic comparison. METHODS: Single-line search strategies were prepared in a text document. Term completeness was ensured with a novel optimization technique. Macros in MS Word converted the syntaxes between databases and interfaces almost automatically. We compared search characteristics, such as number of search terms and databases, and outcomes, such as number of included and retrieved references and precision, from ESM searches and other Dutch academic hospitals identified by searching PubMed for systematic reviews published between 2014 and 2016...

Reusing the data from healthcare information systems can effectively facilitate clinical trials (CTs). How to select candidate patients eligible for CT recruitment criteria is a central task. Related work either depends on DBA (database administrator) to convert the recruitment criteria to native SQL queries or involves the data mapping between a standard ontology/information model and individual data source schema. This paper proposes an alternative computer-aided CT recruitment paradigm, based on syntax translation between different DSLs (domain-specific languages)...
