OBJECTIVES: To study the prevalence of remission and its effect on damage and quality of life (QOL) in Chinese patients with systemic lupus erythematosus (SLE). METHODS: Patients who fulfilled≥4 American College of Rheumatology criteria for SLE were identified. Their remission status at last clinic visits was determined by the European consensus criteria (complete/clinical remission ± immunosuppressive drugs). The increase in SLE damage index (SDI) in the preceding 5 years was compared between patients who were and were not in remission for ≥5 years...

Objective: We assessed whether surgical resection is acceptable for radiological invasive non-small cell lung cancer (NSCLC) that met the current high-risk criteria. Methods: We reviewed 500 clinical-Stage I NSCLCs with a radiological pure-solid appearance. High-risk criterion was defined as follows: (1) preoperative FEV1% ≤ 50% or DLco% ≤ 50%, (2) age > 75y with 50% < FEV1% < 60% or 50% < DLco% < 60%, and (3) three or more severe general comorbidities...

A penalized likelihood (PL) method for structural equation modeling (SEM) was proposed as a methodology for exploring the underlying relations among both observed and latent variables. Compared to the usual likelihood method, PL includes a penalty term to control the complexity of the hypothesized model. When the penalty level is appropriately chosen, the PL can yield an SEM model that balances the model goodness-of-fit and model complexity. In addition, the PL results in a sparse estimate that enhances the interpretability of the final model...

We deeply explore the role of the Gaussian statistics on the solvation dynamics upon the photon excitation of the chromophore. The linear response theory for the fluorescence Stokes shift is investigated. An analytical formulism is presented to recast Stokes shift into the contributions of the equilibrium time correlation functions of the solute-solvent interactions on the excited state surface, and the latter is further reformed and depicted by the time relaxation of the moment. As the first application of our formulism in the molecular dynamics simulations, we verify that the efficiency of the linear response theory relies on the Gaussian characteristics of the dominant moments in terms of the Stokes shift, which is identified by the same relaxation dynamics between those moments and the linear order one...

Overuse of osteoporosis screening in women at low risk of fracture may lead to overdiagnosis, inappropriate treatment and medicalization. The objective of this work was to estimate the proportion of women aged 45 to 64 enrolled in a private health insurance plan in Buenos Aires undergoing hip dual-energy x-ray absorptiometry (DXA) in 2011 without meeting osteoporosis screening criteria. In this cross-sectional study, 4310 women of this age range that had undergone a hip DXA were identified. A randomly selected sub-group of 401 women was then assessed for the presence of risk factors for osteoporosis and complete data were retrieved for 178 women...

BACKGROUND: - PCOS is a heterogeneous disorder and its presentation varies with race and ethnicity. Reproductive age women with PCOS are at increased risk of metabolic syndrome however, it is not clear if prevalence of metabolic syndrome and clustering of its components differs based on race and ethnicity. Moreover, the majority of these women do not undergo routine screening for metabolic syndrome. OBJECTIVES: To compare the prevalence of metabolic syndrome and clustering of its components in women with PCOS in the United States with women in India, Brazil, Finland, and Norway...

Charcoal is a heterogeneous material exhibiting a diverse range of properties. This variability represents a serious challenge in studies that use the properties of natural charcoal for reconstructing wildfires history in terrestrial ecosystems. In this study, we tested the hypothesis that particle size is a sufficiently robust indicator for separating forest wildfire combustion products into fractions with distinct properties. For this purpose, we examined two different forest environments affected by contrasting wildfires in terms of severity: an eucalypt forest in Australia, which experienced an extremely severe wildfire, and a Mediterranean pine forest in Italy, which burned to moderate severity...

Identifying reproducible yet relevant protein features in proteomics data is a major challenge. Analysis at the level of protein complexes can resolve this issue and we have developed a suite of feature-selection methods collectively referred to as Rank-Based Network Analysis (RBNA). RBNAs differ in their individual statistical test setup but are similar in the sense that they deploy rank-defined weights amongst proteins per sample. This procedure is known as gene fuzzy scoring. Currently, no RBNA exists for paired-sample scenarios where both control and test tissues originate from the same source (e...

BACKGROUND: Eosinophilic esophagitis (EoE) is a chronic, immune-mediated disorder of the esophagus characterized by mucosal eosinophilic infiltration. Topical glucocorticoids are considered standard line of treatment, whereas endoscopic dilations are performed for patients presenting with treatment-resistant disease or manifestations of dysphagia and/or food impactions. Efficacy and safety of esophageal dilation in these patients are currently unclear. AIMS: Primary outcomes were to evaluate the efficacy, adverse events, and mortality rates of endoscopic esophageal dilation in patients with EoE...

The regulation of the drinking behavior of animals is usually overlooked, and the traits associated with it are not well defined. We used a unique data set of measurements of individual drinking behavior in turkeys 1) to validate the system of data generation, 2) to develop a methodology to allow clustering of drinking events and splitting behavior into bouts, and 3) to develop traits related to drinking behavior and its regulation and investigate how these traits may be affected by bird genotype. Visits to drinkers were generated by an electronic, custom-made equipment that automatically measures the individual drinking behavior of a large number of turkeys from 3 different genetic lines...

The past decade has seen important developments in thematic apperceptive techniques (TATs), with the creation of new card sets having alternate pictures representing different cultures, new scoring systems becoming available, and increasing international communication of these achievements. However, continuing impediments to the development of a validational literature include lingering mistaken assumptions about the nature of story data, ongoing debates about appropriate psychometric evaluation, and continuing questions about how stimuli and scoring systems should be conceptualized and interpreted...

BACKGROUND: Headache is one of the most common emergency department complaints with three million visits annually in the USA. This is further complicated with 30% of those emergency visits being for a hypertensive disorder of pregnancy. There is no currently well-established guideline for diagnostic imaging with a common concern being ionizing radiation exposure in pregnancy. The purpose of this study was to assess the difference in imaging studies ordered for pregnant and non-pregnant patients who reported to a tertiary care emergency department with headache...

Modal-based acoustoelastic formulation is regarded as the cornerstone of vibro-acoustics and has been widely used for coupling analyses of structure-cavity systems. The controversy and the skepticism surrounding the acoustic velocity continuity with the surrounding vibrating structures have been persistent, calling for a systematic investigation and clarification. This fundamental issue of significant relevance is addressed in this paper. Through numerical analyses and comparisons with wave-based exact solution, an oscillating convergence pattern of the calculated acoustic velocity is revealed...

OBJECTIVE: Our objective was to develop a generalized linear mixed model for predicting seizure count that is useful in the design and analysis of clinical trials. This model also may benefit the design and interpretation of seizure-recording paradigms. Most existing seizure count models do not include children, and there is currently no consensus regarding the most suitable model that can be applied to children and adults. Therefore, an additional objective was to develop a model that accounts for both adult and pediatric epilepsy...

Single-walled carbon nanotubes show promise as nanoscale transistors for nanocomputing applications. This use will require appropriate methods for creating electrical connections between distinct nanotubes, analogous to welding of metallic wires at larger length scales, but methods for performing nanoscale chemical welding are not yet sufficiently understood. This study examines the effect of Ar bombardment on the junction of two crossed single-walled carbon nanotubes, to understand the value and limitations of this method for generating connections between nanotubes...

The von Mises (VM) stress is a common stress measure for finite-element models of tissue mechanics. The VM failure criterion, however, is inherently isotropic, and therefore may yield incorrect results for anisotropic tissues, and the relevance of the VM stress to anisotropic materials is not clear. We explored the application of a well-studied anisotropic failure criterion, the Tsai-Hill (TH) theory, to the mechanically anisotropic porcine aorta. Uniaxial dogbones were cut at different angles and stretched to failure...

Melamine and cyanuric acid have been mixed illegally into food and feed to increase the nitrogen content which results in deceptively high protein contents. As a consequence a maximum level for melamine of 2.5 mg kg(-1) feed was established by the European Union under directive 2002/32/EC. A method is required to quantify melamine and cyanuric acid for control of the maximum level. Therefore Technical Committee (TC) 327 of the European Committee for Standardisation (CEN) commissioned the standardisation of a method for the analysis of melamine and cyanuric acid in animal feed...
