Work-related stress in the banking sector: a study on an Italian aged population of over 2,000 workers

Introduction:In the European Union, the employment rate for the population in the age group 55-64 years has greatly increased in the last two decades. Companies, especially in sectors such as banking, are looking for new strategies to improve the productivity of workers in this age group.Objectives:This study was conceived with the purpose of exploring the associations between job characteristics that could influence stress and certain organizational aspects in a large population of banking workers.Methods:More than 2,000 workers over 50 years of age of an Italian banking group participated in the study. Work-related stress was measured with the Stress Questionnaire (SQ). Organizational aspects of work were measured with a dedicated scale included in the SQ. Demographic aspects were detected by specific questions. Structural equation modelling was used and correlation coefficients were calculated.Results:The results from the structural equation modeling supported the theoretical model. Organizational policies are associated with both stress correlated factors (β=0.468) and perceptions of supervisor support and social support (β=0.710). The perception of both parameters is associated with stress outcomes (β=0.365). The proposed model offered better results than a competitive model, on which a total mediation was tested, rather than a partial one (p<0.001).Conclusions:The results highlight the importance of an integrated assessment of the effects of organizational aspects of work and stress factors to implement the protection of physical and mental health. Further research will help to understand more thoroughly if the issues emerged are effectively related to age. This can be assessed through a case-control study that also includes younger workers.Key words: Work-related stress, ageing, banking sector     

1,2,3-Triazol-carboxanilides and 1,2,3-triazol-(N-benzyl)-carboxamides as BK-potassium channel activators. XII

The chemical structures of many synthetic activators of large-conductance calcium-activated potassium channels (BK channels) satisfy a simple pharmacophore model, consisting of two appropriately substituted phenyl rings connected by a linker of a heterogeneous nature. In this paper, a series of new compounds with modifications of the linker portion of the above pharmacophore are described. In particular, in these new derivatives, the linker portion is represented by a 1,2,3-triazole-carboxamide group, which can be viewed as a combination of two different kinds of linker, independently used in previous series of BK-openers: the amide function and the 1,2,3-triazole ring. The overall finding of this study indicated that the triazole-carboxamide derivatives were generally poorly effective and that this structural modification of the linker is deleterious for activity on BK channels. Therefore, it can be hypothesized that the increase of the steric hindrance of the linker and/or the increase of the distance between the two aromatic portions are negative for the interaction with the biological target.     

Atypical Spitz tumour: a 'chameleon' lesion

It is a common experience that many Spitz naevi deviate from the idealized or stereotypical representation found in the literature, often causing considerable difficulties in distinguishing them from melanoma. The diagnostic term 'atypical Spitz naevus' is used to describe lesions that deviate from the typical appearance of Spitz naevi and which have an uncertain biological significance and prognosis. The term 'Spitz tumour' has been proposed for these lesions, as the term 'naevus' indicates a lesion that is completely benign and presents no risk to the patient. We present a case of atypical Spitz tumour with peculiar atypical clinical and dermatoscopic features. The difficulty in managing this Spitz tumour was aggravated by the clinical diagnosis. In fact, the lesion appeared as a benign and nonmelanocytic lesion, a pigmented dermatofibroma. Our case underlines the difficulties present in the controversial chapter of spitzoid melanocytic lesions. The atypical Spitz tumour is a 'chameleon' lesion that can mimic not only melanocytic, but also nonmelanocytic lesions.     

N6-1,3-diphenylurea derivatives of 2-phenyl-9-benzyladenines and 8-azaadenines: synthesis and biological evaluation as allosteric modulators of A2A adenosine receptors

Some 1-[4-(9-benzyl-2-phenyl-9H-purin-6-ylamino)-phenyl]-3-phenyl-urea derivatives and some 1-[4-(9-benzyl-2-phenyl-9H-8-azapurin-6-ylamino)-phenyl]-3-phenyl-urea derivatives were synthesised and evaluated for their interaction with adenosine receptors. It was found that some of these compounds can act as positive enhancers of agonist and antagonist radioligands for the A(2A) adenosine receptors. This evidence was also strengthened by functional data. Other compounds can act as negative modulators. Furthermore these compounds show inhibitory properties for A(1) and A(3) adenosine receptors.     

Human bocavirus: Current knowledge and future challenges

Human bocavirus(HBoV) is a parvovirus isolated about a decade ago and found worldwide in both respiratory samples, mainly from early life and children of 6-24 mo of age with acute respiratory infection, and in stool samples, from patients with gastroenteritis. Since then, other viruses related to the first HBoV isolate(HBoV 1), namely HBoV 2, HBoV 3 and HBoV 4, have been detected principally in human faeces. HBo Vs are small nonenveloped single-stranded DNA viruses of about 5300 nucleotides, consisting of three open reading frames encoding the first two the non-structural protein 1(NS1) and nuclear phosphoprotein(NP1) and the third the viral capsid proteins 1 and 2(VP1 and VP2). HBoV pathogenicity remains to be fully clarified mainly due to the lack of animal models for the difficulties in replicating the virus in in vitro cell cultures, and the fact that HBo V infection is frequently accompanied by at least another viral and/or bacterial respiratory and/or gastroenteric pathogen infection. Current diagnostic methods to support HBoV detection include polymerase chain reaction, real-time PCR, enzymelinked immunosorbent assay and enzyme immunoassay using recombinant VP2 or virus-like particle capsid proteins, although sequence-independent amplification techniques combined with next-generation sequencing platforms promise rapid and simultaneous detection of the pathogens in the future. This review presents the current knowledge on HBoV genotypes with emphasis on taxonomy, phylogenetic relationship and genomic analysis, biology, epidemiology, pathogenesis and diagnostic methods. The emerging discussion on HBoV s as true pathogen or innocent bystander is also emphasized.     

Transarterial radioembolization for hepatocellular carcinoma: An update and perspectives

In the last decade trans-arterial radioembolization has given promising results in the treatment of patients with intermediate or advanced stage hepatocellular carcinoma (HCC), both in terms of disease control and tolerability profile. This technique consists of the selective intra-arterial administration of microspheres loaded with a radioactive compound (usually Yttrium⁹⁰), and exerts its therapeutic effect through the radiation carried by these microspheres. A careful and meticulous selection of patients is crucial before performing the radioembolization to correctly perform the procedure and reduce the incidence of complications. Radioembolization is a technically complex and expensive technique, which has only recently entered clinical practice and is supported by scant results from phase III clinical trials. Nevertheless, it may represent a valid alternative to transarterial chemoembolization (TACE) in the treatment of intermediate-stage HCC patients, as shown by a comparative retrospective assessment that reported a longer time to progression, but not of overall survival, and a more favorable safety profile for radioembolization. In addition, this treatment has reported a higher percentage of tumor shrinkage, if compared to TACE, for pre-transplant downsizing and it represents a promising therapeutic option in patients with large extent of disease and insufficient residual liver volume who are not immediately eligible for surgery. Radioembolization might also be a suitable companion to sorafenib in advanced HCC or it can be used as a potential alternative to this treatment in patients who are not responding or do not tolerate sorafenib.
