METHOD This study aimed at identifying factors that were associated with aggression among a sample of 720 substance-using wome...
AIMS In heart failure, various biomarkers are established for diagnosis and risk stratification; however, little is known about the relevance of serial measurements during an episode worsening heart failure (WHF). This study sought to investigate the trajectory of natriuretic peptides and multiple novel biomarkers during hospitalization for WHF and to determine the best time point to predict ou...
BACKGROUND As the most populous nation in the world, China has now becoming an emerging ageing society. Shanghai is the first city facing the challenge of ageing demographics. Against this background, a study that employs self-rated health (SRH) assessment system was designed to explore the health status of Shanghai elders, and learn their attitudes toward health issues; as well as to investiga...
Background: Interleukin 17 (IL-17) is a pro-inflammatory cytokine mainly secreted by activated TH-17 cells and involved in inflammatory immune responses. Interleukin 23 (IL-23) sustains the development of inflammation and is considered a check point. Aim: the aim of the present study was to investigate the association between serum IL-17A, IL-17F and serum IL23receptor variants in Saudi women w...
Supersaturated design (SSD) has received much interest because of its potential in factor screening experiments. Recently, Chen and Liu [Chen, J., Liu, M.Q., 2008a. Optimal mixedlevel k-circulant supersaturated designs. J. Statist. Plann. Inference 138, 4151–4157] explored the construction of E(fNOD )-optimalmixed-level SSDs using k-cyclic generators. As an extension, this paper further studies...
A 2-hued coloring of a graph G (also known as conditional (k, 2)-coloring and dynamic coloring) is a coloring such that for every vertex v ∈ V (G) of degree at least 2, the neighbors of v receive at least 2 colors. The smallest integer k such that G has a 2-hued coloring with k colors, is called the 2-hued chromatic number of G and denoted by χ2(G). In this paper, we will show that if G is a re...
Background: Despite the available evidence on benefits of COVID-19 vaccine, its low uptake and hesitancy remain a challenge. This study assessed individual, administrative, social, demographic factors associated with vaccine uptake. Methods: Analytical cross-sectional design was used. The data collected using structured questionnaires administered to 384 respondents key informant interview guid...
INTRODUCTION The aim of our study was to investigate the extent to which Instructions to authors of the Croatian open access (OA) journals are addressing ethical issues. Do biomedical journals differ from the journals from other disciplines in that respect? Our hypothesis was that biomedical journals maintain much higher publication ethics standards. MATERIALS AND METHODS This study looked at...
multivariate control charts such as hotelling`s t^ 2 and x^ 2 are commonly used for monitoring several related quality characteristics. these control charts use correlation structure that exists between quality characteristics in an attempt to improve monitoring. the purpose of this article is to discuss some issues related to the g chart proposed by levinson et al. [9] for detecting shifts in ...
