Psychosocial safety climate as a lead indicator of workplace bullying and harassment, job resources, psychological health and employee engagement
2011
Psychosocial safety climate (PSC) is defined as shared perceptions of organizational policies, practices and procedures for the protection of worker psychological health and safety, that stem largely from management practices. PSC theory extends the Job Demands-Resources (JD-R) framework and proposes that organizational level PSC determines work conditions and subsequently, psychological health problems and work engagement. Our sample was derived from the Australian Workplace Barometer project and comprised 30 organizations, and 220 employees. As expected, hierarchical linear modeling showed that organizational PSC was negatively associated with workplace bullying and harassment (demands) a…
CD146+ bone marrow osteoprogenitors increase in the advanced stages of primary myelofibrosis
2008
Abstract CD146+ bone marrow stromal cells have been recently recognized as clonogenic osteoprogenitors able to organize a complete hematopoietic microenvironment. In this study we used immunohistochemical analysis to investigate the contribution of CD146+ bone marrow osteoprogenitors to the stromal remodeling occurring in the different stages of primary myelofibrosis. We found that CD146+ cells sited at the abluminal side of the bone marrow vessels and branching among hematopoietic cells significantly increased in the advanced stages of primary myelofibrosis (p<0.001), paralleling the extent of fibrosis (r=0.916, p<0.0001) and the microvascular density (r=0.883, p<0.0001). Coherently with a…
MFAP5 Loss-of-Function Mutations Underscore the Involvement of Matrix Alteration in the Pathogenesis of Familial Thoracic Aortic Aneurysms and Dissec…
2014
Thoracic aortic aneurysm and dissection (TAAD) is an autosomal-dominant disorder with major life-threatening complications. The disease displays great genetic heterogeneity with some forms allelic to Marfan and Loeys-Dietz syndrome, and an important number of cases still remain unexplained at the molecular level. Through whole-exome sequencing of affected members in a large TAAD-affected family, we identified the c.472CT (p.Arg158(∗)) nonsense mutation in MFAP5 encoding the extracellular matrix component MAGP-2. This protein interacts with elastin fibers and the microfibrillar network. Mutation screening of 403 additional probands identified an additional missense mutation of MFAP5 (c.62GT …
Does organized sport participation during youth predict healthy habits in adulthood? A 28-year longitudinal study
2018
Health behaviors in youth can predict the same behaviors later in life, but the role of sport participation in predicting healthy lifestyle habits is unclear. This study aimed to investigate the association between participation in organized youth sport and adult healthy lifestyle habits. Data from the longitudinal Cardiovascular Risk in Young Finns Study (YFS) with a 28-year follow-up were used. The participation in sport-club training sessions was self-reported by 9-18-year-olds in 1983 and 1986 (n = 1285). During 2011, participants (aged 37-43-year old) reported their smoking status, alcohol consumption, fruit and vegetable consumption, and physical activity. Odd ratios (OR) were calcula…
Acute stress and working memory: The role of sex and cognitive stress appraisal
2016
Sex is considered a moderating factor in the relationship between stress and cognitive performance. However, sex differences and the impact of cognitive stress appraisal on working memory performance have not received much attention. The aim of this study was to investigate the role of physiological responses (heart rate and salivary cortisol) and cognitive stress appraisal in Working Memory (WM) performance in males and females. For this purpose, we subjected a comparable number of healthy young adult males (N=37) and females (N=45) to a modified version of the Trier Social Stress Test (TSST), and we evaluated WM performance before and after the stress task. Females performed better on att…
Can Graduated Compressive Stockings Reduce Muscle Activity During Running?
2017
Purpose: Graduated compressive stockings (GCS) have been suggested to influence performance by reducing muscle oscillations and improving muscle function and efficiency. However, no study to date has analyzed the influence of GCS on muscle activity during running. The objective of the study was to analyze the influence of GCS on the perception of comfort and muscle activation of the main muscles of the lower leg during running. Method: Thirty-six participants ran on a treadmill with (GCS) or without (control) GCS. The running tests consisted of a 10-min warm-up followed by a 20-min intense run at 75% of the athlete’s maximal aerobic speed. Surface electromyography of the tibialis anterior, …
Descriptive retrospective study analyzing relevant factors related to dental implant failure
2019
Background The objective of this retrospective descriptive study was to analyze the characteristics of incident reports provided by dentists while using a specific brand of dental implants. Material and Methods The study was carried out in collaboration with Oxtein Iberia S.L.®, with the company providing access to the incident database in order to evaluate the characteristics of incidents from January 2014 to December 2017 (a total of 917 over four years). The data sheet recorded different variables during each of the stages of implant treatment, from initial implant placement to subsequent prosthetic rehabilitation. These variables included age, sex, systemic pathologies, smoking habits, …
Condylar growth after non-surgical advancement in adult subject: a case report.
2007
Abstract Background A defect of condylar morphology can be caused by several sources. Case report A case of altered condylar morphology in adult male with temporomandibular disorders was reported in 30-year-old male patient. Erosion and flattening of the left mandibular condyle were observed by panoramic x-ray. The patient was treated with splint therapy that determined mandibular advancement. Eight months after the therapy, reduction in joint pain and a greater opening of the mouth was observed, although crepitation sounds during mastication were still noticeable. Conclusion During the following months of gnatologic treatment, new bone growth in the left condyle was observed by radiograph,…
Health anxiety and attentional bias: the time course of vigilance and avoidance in light of pictorial illness information.
2011
Cognitive-behavioral models of health anxiety stress the importance of selective attention not only towards internal but also towards external health threat related stimuli. Yet, little is known about the time course of this attentional bias. The current study investigates threat related attentional bias in participants with varying degrees of health anxiety. Attentional bias was assessed using a visual dot-probe task with health-threat and neutral pictures at two exposure durations, 175ms and 500ms. A baseline condition was added to the dot-probe task to dissociate indices of vigilance towards threat and difficulties to disengage from threat. Substantial positive correlations of health anx…
Reasoned and implicit processes in heavy episodic drinking: An integrated dual-process model.
2019
Objectives University students commonly engage in heavy episodic drinking (HED), which contributes to injury risk, deleterious educational outcomes, and economic costs. Identification of the determinants of this risky behaviour may provide formative evidence on which to base effective interventions to curb HED in this population. Drawing from theories of social cognition and dual-process models, this study tested key hypotheses relating to reasoned and implicit pathways to action for HED in a sample of Australian university students who drink alcohol. Design A two-wave correlational design was adopted. Methods Students (N = 204) completed self-reported constructs from social cognition theor…
