Cyclic Vomiting Syndrome (CVS) is characterized by recurrent, discrete episodes of vomiting between periods of completely normal health. Cannabinoid-induced CVS have been documented in adults but the link is often overlooked in children. To our knowledge this one of the youngest reported cases of cannabinoid induced CVS. A 14.5-year-old male had been admitted to the hospital 9 times with episod...

Cyclic vomiting syndrome (CVS) is characterized by intense vomiting, recurrent emergency department visits, and return to usual health status between episodes. This syndrome was first described in 1882 in a case series of pediatric patients, but there is growing understanding that CVS may occur in other age groups. This case report describes a 23-year-old with a history of CVS diagnosed in adol...

Collective variables (CVs) are a fundamental tool to understand molecular flexibility, to compute free energy landscapes, and to enhance sampling in molecular dynamics simulations. However, identifying suitable CVs is challenging, and is increasingly addressed with systematic data-driven manifold learning techniques. Here, we provide a flexible framework to model molecular systems in terms of a...

BACKGROUND Cardiovascular diseases (CVD) are the leading cause of death in the world today. Risk factors are those factors that influence the development of CVD. Risk factors can be divided into materialistic (genetic predisposition, smoking, alcohol) and non-materialistic (psychosocial factors). Our goal is to note the role of the health system, to emphasize the importance of psychosocial fact...

ABSTRACT We report on our second campaign to search for old nova shells around cataclysmic variables (CVs). Our aim was test the theory that eruptions cause cycles in mass transfer rates of CVs. These change behaviour CVs during their intereruption periods. examined Hα images 47 objects and found no new any targets. Combining latest results with those previous (Sahman et al.), searches by Schmi...

Aims. We present discovery observations of the new cataclysmic variable star (CV) 1RXS J092737.4-191529, as well as spectra and photometry of SY Vol. The selection technique that turned up these two CVs is described; it should be efficient for finding dwarf novae with high outburst duty cycles. Methods. Two very common observational features of CVs, namely optical variability and X-ray emission...

A personal selection of noteworthy X-ray results on CVs are presented, with emphasis on XMM-Newton and Chandra observations. Progressing roughly from broad-band view to narrow-band, high spectral resolution studies, I summarize: the energy balance of polars; X-ray confirmation of IPs; eclipses in non-magnetic CVs; search for magnetism in " non-magnetic " CVs; multi-temperature plasma emission f...

BACKGROUND Cyclic Vomiting Syndrome (CVS) is a well-recognized functional gastrointestinal disorder in children but its presentation is poorly understood in adults. Genetic differences in pediatric-onset (presentation before age 18) and adult-onset CVS have been reported recently but their clinical features and possible differences in response to therapy have not been well studied. METHODS Th...

Background: Computer-digital vision syndrome (CVS) is a common occupational disease. Objective: This study aims to determine the frequency of CVS and its associated factors in students private university located north Lima City. Methods: The was an observational, descriptive, cross-sectional one. variable CVS, which assessed using Computer Vision Syndrome Questionnaire (CVS-Q). Results: analysi...

Abstract Background Stroke is the most common acquired neurological disease in adult population worldwide with an incidence of 16 million new cases every year responsible for about 6.1 deaths and 130.6 disability-adjusted life-years (DALYs). The objectives this work were to study level stroke awareness proper response suspected patients urban rural areas Tanta City, Egypt. was conducted on 1869...
