Work- related Stress, over-nutrition and cognitive disability.

Work-related stress may exert a negative impact on a variety of physical and psychological attributes relating to the health of employees and work organizations. Several studies conducted in Italy have shown that workers and employees who express less satisfaction show increased symptoms of obesity and cognitive disability. The latest evidence underlines the pathogenic relationship between stress and neurological disease through inflammatory neuro- immune activation. The aim of this review was to describe the relationship between workplace stress and adverse changes in lifestyle that develop into obesity, neuroinflammation and cognitive dysfunction. The molecular mechanisms involved and guidelines for the prevention of these trends are discussed briefly.

Gambling and the need for new responses in Public Health with an addiction "sine substantia".

BACKGROUND: The Gambling Disorder (GD) was recently defined as a behavioral addiction by the "The Diagnostic and Statistical Manual of Mental Disorders IV"( DSM-V) since the clinical, neurobiological and psychopathological similarities led it to be defined it as an addiction "sine substantia". The aim of this study is to formulate an "identikit" of the gambler, to evaluate a possible association between GD / emotional specific factors and the correlation between GD / substance abuse, GD / suicide. METHOD: In the study, 41 subjects were included (31 males and 10 females) and all were diagnosed with GD. A questionnaire was distributed containing 24 questions deriving from South Oaks Gambling Screen and the DSM-IVTR. RESULTS: The study showed that 51% of the respondents makes use of alcohol and / or drugs; that 73% of the patients started playing in order to relieve feelings of dysphoria and suffering consequences on work as well as family life (51%). A great deal of the respondents were indebted (39%) to the extent of needing to ask for loans from usurer (17%). Furthermore, 41% of the respondents in the sample showed that GD could be transformed into an alarming risk of suicide. DISCUSSION: The correlation between GD and drug abuse may depend on the brain function and the neural circuits that support impulsive behavior and the gratification mechanisms. Emotional experiences (stress, low level of education, divorce, poor social support) could constitute a possible risk factor that increases the GD. The committed offenses related to gambling could be explained by "loss of control". CONCLUSIONS: The results of the present study contributes to the body of knowledge regarding the size of phenomenon from a statistical and epidemiological point of view, suggesting the necessity for targeted information on the risks connected to GD in order to capture early warning signs which enables the intervention with suitable strategies.

Correlation between cadmium and blood counts in workers exposed to urban stressor.

The objective of this study was to assess the exposures to cadmium (Cd) in urban workers and the association between Cd exposure and values of blood counts. Urinary Cd, blood Cd, and blood counts were obtained from 355 outdoor workers; a subgroup of 99 subjects were monitored to evaluate personal exposure to airborne Cd. The mean value of personal exposure to Cd was 1.5 ng/m3 for traffic assistants and 1.2 ng/m3 for drivers. Urinary and blood Cd were correlated to the airborne Cd (respectively r=3 and r=4). The multiple linear regression models showed the associations among white blood cell, the percentage of neutrophils (NEU%), the percentage of lymphocytes (LYM%), and the concentrations of blood Cd (respectively R2=27, R2=37, R2=581). The subjects with blood Cd values higher than 1.2 µg/L showed an increase of LYM% mean values and a decrease of NEU% mean values with respect to the group with blood Cd values lower than 1.1 µg/L.

Cadmium blood/urine levels and blood pressure in workers occupationally exposed to urban stressor.

BACKGROUND: Cadmium (Cd) is a metal, which induces hypertension in animals. This may not be relevant to the human population because the number of studies is inconsistent. OBJECTIVE: Our aim is to identify an association between levels of blood/urinary cadmium and blood pressure in a group of employees of the municipal police assigned to outdoor activities. MATERIALS AND METHODS: 349 subjects of both sexes were enrolled and sorted on the basis of gender, job function and smoking habit. Blood and urinary cadmium levels and blood pressure readings were collected for each subject. The data were subjected to statistical evaluation. Pearson correlation coefficient between the variables and a linear regression curve was drawn. After eliminating the confounding factors, the multiple linear regression analysis assessed statistical differences. Associations were considered significant at p < 0.05. RESULTS AND CONCLUSIONS: The Pearson correlation showed a positive association between urinary cadmium levels and blood pressure especially for groups of women and non-smokers. The simple and multiple linear regression and t-tests confirmed these associations and underlined the influence cadmium has on diastolic blood pressure, higher than systolic blood pressure. No association was found between blood cadmium and blood pressure. In conclusion, we can say that there is a statistically significant association between urinary cadmium and diastolic blood pressure, supporting the hypothesis that cadmium has a long-term effect on diastolic blood pressure (BP).

[Stress and information-communication technologies: from videoterminal to web]. / Stress e Information-Communication Technologies: dal videoterminale al Web.

The relationship between stress and new technologies has always been a vexed question. Sociologists and philosophers say technology is a double edged sword, on one hand it increases the potential of human senses, while on the other hand it forces man to adopt rhythms and conditions not natural but artificial, with consequences for his physical and mental health. Modern Cognitive Ergonomic tries to analyze to technology, interacting with mental functions, causes stress and it tries to offer the most appropriate technological solutions for human work. From our analysis it emerges that the old media have an influence on mood causing episodes of insomnia, irritability, anxiety, etc., even if in a way that cannot be completely evaluated. Contrariwise, a controlled use of the web can improve the communication and the interacting abilities in patients with psychosocial distress and low social skills. Nielsen's Heuristics are a great tool to value methods of informatical and media interfaces.

Occupational exposure to traffic pollutants and peripheral blood counts.

Aim of the study is to evaluate whether occupational exposure to low doses of pollutants present in the air of the city selected for the study could cause alterations in peripheral blood counts in workers of the Municipal Police with outdoor tasks vs workers with indoor tasks. 279 non smoker males were enrolled and divided on the basis of their different kind of task. The dosage of air pollutants was carried out through the use of personal air samplers on a representative group of workers. Data obtained were subject to statistical evaluation consisting of Homogeneity of variance test, ANOVA univariate test with post hoc Bonferroni correction, Jonckheere-Terpstra test and multiple linear regression analysis. The differences were considered statistically significant when p values were lower than 0.05. Mean levels of RBC, HB, MCHC, WBC and neutrophil cells were significantly higher in traffic policemen and police drivers compared to controls (workers with indoor tasks). Mean levels of MCV, MCH and lymphocytes were significantly lower in traffic policemen and police drivers compared to controls. These results were confirmed by Multiple linear regression test and Jonckheere-Terpstra test. The results suggest that prolonged occupational exposure to low doses of traffic pollutants can alter some lines of the hematopoietic system in exposed workers.

[Meta analysis indices of genotoxic damage in urban pollution exposed workers]. / Meta analisi degli indici di danno genotossico in lavoratori esposti a inquinamento urbano.

OBJECTIVES: The aim of this study is to examine if urban pollution can modify indices of genotoxic damage. METHODS: Research of articles inherent in the evaluation of these alterations. Differents categories of exposed workers are included in the study (cases, in number of 7287) and compaired with no exposed workers (controls, in number of 8054). To calculate the result of meta-analysis the Effect Size (ES) was used and the confidence interval was calculated. RESULTS: In this category we evaluated 54 studies and we observed significantly differences in the complex. CONCLUSIONS: Starting from the individual variables analysis investigated, between exposed and not exposed group, we underline the utility to deepen the studies concerning of these parameters, to appreciate their benefits and to safeguard health of exposed workers.
