Spinal ependymoma in adults: a multicenter investigation of surgical outcome and progression-free survival

2018

OBJECTIVESpinal ependymomas are rare glial neoplasms. Because their incidence is low, only a few larger studies have investigated this condition. There are no clear data concerning prognosis and therapy. The aim of the study was to describe the natural history, perioperative clinical course, and local tumor control of adult patients with spinal ependymomas who were surgically treated under modern treatment standards.METHODSThe authors performed a multicenter retrospective study. They identified 158 adult patients with spinal ependymomas who had received surgical treatment between January 2006 and June 2013. The authors analyzed the clinical and histological aspects of these cases to identif…

Genome-wide analysis for micro-aberrations in familial exstrophy of the bladder using array-based comparative genomic hybridization

2007

OBJECTIVE: Exstrophy of the bladder (EB) is part of the bladder-exstrophy-epispadias complex (BEEC). Because familial occurrence of BEEC is rare, exogenous factors are thought to play a major role in the etiology of most BEEC cases. We aimed to investigate a possible genetic basis of BEEC in a consanguineous kindred of Moroccan origin with three members showing the same phenotypic expression of BEEC. PATIENTS AND METHODS: The three affected males (two cousins and their maternal uncle) all presenting with nonsyndromic classic EB, were born in Morocco or The Netherlands. One Moroccan patient had an open bladder surface for 22 years due to late surgical reconstruction, avoided upright posture …

Factors associated with the activities of safety representatives in Spanish workplaces

2007

Objective: To describe the activities of safety representatives in workplaces in Spain. Methods: A specific questionnaire was applied to a representative sample of safety representatives. Activities developed during the past year, presented in a closed ended list, were categorised into three groups: information and advising; participation in occupational health management; and pressure on or negotiation with employers. Personal phone interviews were conducted from September to December 2004. A sample of 1201 interviews was attained. Crude and multivariate analyses were carried out. Results: Spanish safety representatives were mostly men (76%), aged 26 to 45 years (62%), with fixed contracts…

The "exposome" concept - how environmental risk factors influence cardiovascular health.

2019

There is general consensus that environmental pollution and non-chemical stressors contribute to the incidence and prevalence of chronic noncommunicable disease (e.g. cardiovascular, metabolic and mental). Clinical and epidemiological studies support that air pollution and traffic noise are associated with a higher risk for cardiovascular disease and significantly contribute to overall mortality. In this respect, the “exposome” provides a comprehensive description of lifelong exposure history. A recent publication using an updated global exposure-mortality model found that the global all-cause mortality rate attributable to ambient air pollution by PM2.5 and O3 was 8.79 (95% CI 7.11–10.41) …

Concomitant dental injuries in maxillofacial fractures - a retrospective analysis of 1219 patients

2014

BACKGROUND/AIM: Traumatic dental injuries are frequently combined with maxillofacial fractures, but literature addressing this topic is rare. In a retrospective study, the frequency of dental lesions in inpatients with traumatic facial injuries was analyzed. MATERIAL AND METHODS: All patients referred to the Department of Oral and Maxillofacial Surgery of the University Medical Center of the Johannes Gutenberg-University Mainz for inpatient treatment due to facial fractures between January 2001 and December 2007 were analyzed regarding the type of fracture, its localization, and potential concomitant dental injuries. In addition a systematic review was performed to compare the findings of t…

Classification of orbital exenteration and reconstruction

2017

Orbital exenteration (OE) is considered to be a mutilating surgical procedure reserved for relentlessly progressive neoplastic disorders or extensive facial trauma with unfavourable eye involvement. Malignant tumours, accounting for the majority of ablative orbital surgeries, may be caused by primary orbital tumours or secondarily by neoplasias from the surrounding skin, the maxillary sinus or intracranial malignomas. Orbital exenteration following trauma is mostly caused by penetrating globe defects or extended infections with the danger of intracranial effects. Thoughtful resection planning, the exploitation of reconstructive possibilities as well as the consideration of adjuvant therapy …

Wording effects and the factor structure of the 12-item General Health Questionnaire (GHQ-12)

2021

The 12-item version of the General Health Questionnaire (GHQ-12) has become a popular screening instrument with which to measure general psychological health in different settings. Previous studies into the factorial structure of the GHQ-12 have mainly supported multifactor solutions, and only a few recent works have shown that the GHQ-12 was best represented by a single substantive factor when method effects associated with negatively worded items were considered. Confirmatory factor analysis was applied to compare competing measurement models from previous research, including correlated traits-correlated methods and correlated traits-correlated uniquenesses approaches, to obtain further e…

Factorial Structure and Psychometric Properties of a Brief Scale of the Condom Use Self-Efficacy for Spanish-Speaking People

2018

Background. Studies have shown the role played by perceived self-efficacy in explaining condom negotiation and condom use. Aims. The factorial structure and the psychometric properties of the Brief Condom Use Self-Efficacy Scale are presented. Method. The study included 368 men and 456 women aged 17 to 55 years ( Mage = 25.01, SD = 6.93). Results. Exploratory factor analysis yielded three factors: fear of rejection, impulse control, and condom acquisition and negotiation, which together accounted for 68% of the total variance. That structure was confirmed through confirmatory factor analysis. Cronbach’s alpha for the Brief Condom Use Self-Efficacy Scale was .71. The scale provided adequate…
