Plasma leptin and vascular endothelial growth factor (VEGF) in normal subjects at high altitude (5050 m)
2013
Context: High altitude (HA) is a model of severe hypoxia exposure in humans. We hypothesized that nocturnal hypoxemia or acute maximal exercise at HA might affect plasma leptin and VEGF levels. Objectives: Plasma leptin, VEGF and other metabolic variables were studied after nocturnal pulse oximetry and after maximal exercise in healthy lowlanders on the 3rd-4th day of stay in Lobuche (5050 m, HA) and after return to sea level (SL). Results: Leptin was similar at SL or HA in both pre- and post-exercise conditions. Pre-exercise VEGF at HA was lower, and cortisol was higher, than at SL, suggesting that nocturnal intermittent hypoxia associated with periodic breathing at HA might affect these v…
Leptin and leptin receptor expression in asthma.
2009
Background The adipokine leptin is a potential new mediator for bronchial epithelial homeostasis. Asthma is a chronic inflammatory disease characterized by airway remodeling that might affect disease chronicity and severity. TGF-β is a tissue growth factor the dysregulation of which is associated with airway remodeling. Objective We sought to determine whether a bronchial epithelial dysfunction of the leptin/leptin receptor pathway contributes to asthma pathogenesis and severity. Methods We investigated in vitro the presence of leptin/leptin receptor on human bronchial epithelial cells. Then we studied the effect of TGF-β and fluticasone propionate on leptin receptor expression. Finally, th…
Multilevel Models in the Explanation of the Relationship between Safety Climate and Safe Behavior
2013
AbstractThis study examines the relationships between components of organizational safety climate, including employee attitudes to organizational safety issues; perceptions of the physical working environment, and evaluations of worker engagement with safety issues; and relates these to self-reported levels of safety behavior. It attempts to explore the relationships between these variables in 1189 workers across 78 work groups in a large transportation organization. Evaluations of safety climate, the working environment and worker engagement, as well as safe behaviors, were collected using a self report questionnaire. The multilevel analysis showed that both levels of evaluation (the work …
Supportive and palliative care in people with cirrhosis: International systematic review of the perspective of patients, family members and health pr…
2018
Background & Aims People with cirrhosis have unmet needs, which could benefit from a palliative care approach. Developing effective services needs to be based on evidence from those with personal experience. This review aims to explore; patient and family perspectives of perceived needs including communication; health professionals' perspectives on delivery of care and improving palliative care between specialities. Methods A literature search was conducted in Medline, Embase and CINAHL using key words reporting on the perspectives of patients with liver cirrhosis (18 years and over), family members or health professionals on the provision of care in liver cirrhosis. Study quality was asses…
Early Lung Function Abnormalities in Acromegaly.
2014
BACKGROUND: Acromegaly is an insidious disorder caused by a pituitary growth hormone (GH)-secreting adenoma resulting in high circulating levels of GH and insulin-like growth factor I (IGF-I). Respiratory disorders are common complications in acromegaly, and can severely impact on quality of life, eventually affecting mortality. OBJECTIVES: The present study aimed to explore structural and functional lung alterations of acromegalic subjects. METHODS: We enrolled 10 consecutive patients (M/F: 5/5) affected by acromegaly. In all patients, magnetic resonance imaging (MRI) revealed the presence of pituitary tumor. All patients underwent clinical, lung functional, biological, and radiological as…
What proportion of chronic obstructive pulmonary disease outpatients is eligible for inclusion in randomized clinical trials?
2013
<b><i>Background and Objective:</i></b> We aimed to explore to what extent an unselected population of chronic obstructive pulmonary disease (COPD) outpatients would be eligible for inclusion in randomized clinical trials (RCTs). <b><i>Methods:</i></b> Retrospective analysis of the clinical records of outpatient subjects with an ascertained diagnosis of COPD. COPD outpatients were assessed against the following inclusion criteria: 40 < age < 80 years, current or former smokers, forced expiratory volume in the first second (FEV<sub>1</sub>) <70% predicted, no long-term oxygen therapy, no other concomitant lung diseases and …
Are Asthmatics Enrolled in Randomized Trials Representative of Real-Life Outpatients?
2014
<b><i>Background/Objective:</i></b> This study was aimed at exploring to what extent populations enrolled in randomized controlled trials (RCTs) of inhalation combination treatment for mild/moderate asthma in adults are fully representative of ‘real-life' populations. The following is a retrospective analysis of the clinical records of outpatient subjects with an ascertained diagnosis of asthma. <b><i>Methods:</i></b> A retrospective analysis was performed. Stable conditions, such as smoking habit and chronic diseases other than asthma, were identified as exclusion criteria for RCTs. The selected criteria were then applied to asthmatic outpati…
Personality and attitudinal correlates of meat consumption: Results of two representative German samples
2017
Abstract The vast amount of meat consumed in the Western world is critically discussed with regard to negative health consequences, environmental impact, and ethical concerns for animals, emphasizing the need to extend knowledge regarding the correlates of meat consumption in the general population. In the present article, we conducted two studies examining the associations between meat consumption and personality traits, political attitudes, and environmental attitudes in two large German representative samples (Ntotal = 8,879, aged 18–96 years). Cross-sectional data on frequency of meat consumption, socio-demographics, personality traits, and political and environmental attitudes were col…
Do neurologists agree in diagnosing drug resistance in adults with focal epilepsy?
2019
Objective: To evaluate interrater agreement in categorizing treatment outcomes and drug responsiveness status according to the International League Against Epilepsy (ILAE) definition of drug-resistant epilepsy. Methods: A total of 1053 adults with focal epilepsy considered by the investigators to meet ILAE criteria for drug resistance were enrolled consecutively at 43 centers and followed up prospectively for 18-34 months. Treatment outcomes for all antiepileptic drugs (AEDs) used up to enrollment (retrospective assessment), and on an AED newly introduced at enrollment, were categorized by individual investigators and by 2 rotating members of a 16-member expert panel (EP) that reviewed the …
Information sources and knowledge on vaccination in a population from southern Italy: The ESCULAPIO project
2016
Vaccine knowledge of the general population is shaped by different information sources and strongly influences vaccination attitudes and uptake. The CCM-Italian Ministry of Health ESCULAPIO project attempted to identify the role of such information sources, in order to address adequate strategies to improve information on vaccines and vaccine preventable diseases. In the present study, data on 632 adults from Southern Italy regarding information sources were collected, and their perceived and actual knowledge on vaccinations were compared and analyzed in relation to socio-demographic characteristics and information sources. The main reported reference sources were general practitioners (GPs…
