Job insecurity is a growing phenomenon, typical of an employment context characterised by high rates of temporary work and unemployment. Previous research has shown a direct relationship between job insecurity and mental health impairment. The present analysis goes into this relationship in depth, studying the moderating role of coping strategies and predicting that men and women implement different types of strategies. A sample of 1.008 workers is analysed, 588 women and 420 men. The Tobin CSI scale was used to analyse the coping strategies, in addition to JIS-8 to assess job insecurity, the MOS Perceived Social Support Survey and the GHQ-28 test to evaluate mental health. Then, a hierarchical linear regression was designed to study the moderating role of 8 coping strategies of job insecurity and 4 mental health subscales in men and women, separately. Results illustrate that coping strategies play a moderating role in the relationship between job insecurity and mental health. However, the aggravating role of disengagement coping strategies is more relevant than the buffering role of engagement strategies. On the other hand, women implement a greater number of coping strategies, with more positive results for mental health. Also, in the relationship between job insecurity and mental health the most important strategies are the ones related to social interaction inside and outside an organisation, and these are the main ones used by women. It therefore follows that strengthening rich social relationships inside and outside the working environment is a guarantee of well-being.

The objective of this study was to examine the clinical significance of polymicrobial bacteremia involving Pseudomonas aeruginosa. Two hundred forty-eight episodes of Pseudomonas aeruginosa bacteremia, 43 of which were polymicrobic, were studied prospectively over a 6-year period. Three sets of blood cultures were obtained for each patient. Positive results for all three blood cultures were found more frequently in patients with polymicrobial infection, who were older than those with monomicrobial infection. Patients with polymicrobial bacteremia also were worse clinically and developed shock more frequently. Crude mortality was higher in patients with polymicrobial infection. A multivariate analysis revealed three variables significantly and independently associated with polymicrobial Pseudomonas aeruginosa bacteremia: higher age, poor clinical status of the patient, and positive results for all blood cultures obtained.

<p>Faced with the growing instability resulting from the world economic crisis, job insecurity gains relevance in the study of occupational health. In order to analyse the consequences of job insecurity on mental health, a reference document is provided including the empirical research advances in the current framework. This systematic review follows a meta-analytical technique through 56 independent samples with 53,405 participants in total.<em> </em>The analysis offers a significant correlation between subjective job insecurity and mental health. Thus, it has been found that job insecurity is related to the risk or presence of depression, anxiety and emotional exhaustion, as well as to general low satisfaction with life, international comparisons are made, and negative results among workers regardless of the economic situation of the countries are highlighted, too. Moreover, methodological and conceptual contributions have been made in terms of the quality of the metrics applied. Job insecurity appears as a major problem for workers’ mental health, generating devastating effects on all kind of professional profiles and economic contexts. </p>

SummaryDengue, similar to other arboviral diseases, exhibits complex spatiotemporal dynamics. Even at town or village level, individual-based spatially explicit models are required to correctly reproduce epidemic curves. This makes modelling at the regional level (province, country or continent) very difficult and cumbersome. We propose here a first step to build a hierarchized model by constructing a simple analytical expression which reproduces the model output from macroscopic parameters describing each 'village'. It also turns out to be a good approximation of real urban epidermic outbreaks. Subsequently, a regional model could be built by coupling these equations on a lattice.keywords dengue, urban epidermics, multi-scale models, Easter Island, Brazil, Lima

Moderate PPM appears to be a strong and independent predictor of cardiac events and advanced functional class in young and middle-aged patients undergoing AVR for severe stenosis. However, it is possible that it has no impact on overall mortality.

BackgroundThe impact of patient-prosthesis mismatch (PPM) on early outcomes in young and middle-aged patients undergoing conventional aortic valve replacement for severe aortic stenosis remains unknown. Our objective was to evaluate the incidence of some degree of PPM and its influence on early mortality and morbidity.MethodsWe analyzed our single center experience in all patients <70 years undergoing first-time isolated aortic valve replacement for severe stenosis in our center from September 2007 to September 2011. PPM was defined as an indexed effective orifice area ≤ 0,85 cm2/m2. The influence of PPM on early mortality and postoperative complications was studied using propensity score analysis. Follow up at 30 postoperative days was 100% complete.ResultsOf 199 patients studied, 61 (30,7%) had some degree of PPM. PPM was associated with an increased postoperative mortality (OR = 8,71; 95% CI = 1,67–45,29; p = 0,04) and major postoperative complications (OR = 2,96; CI = 1,03–8,55; p = 0,044). However, no association between PPM and prolonged hospital or ICU stay was demonstrated.ConclusionsModerate PPM is a common finding in young and middle-aged patients undergoing surgery for aortic valve replacement due to severe stenosis. In addition, its influence on early outcomes may be relevant.
