[Alcohol and work. Consensus Document of the La.R.A. (Workers representing a risk for others) group]. / Alcol e Lavoro. Documento di consenso del gruppo La.R.A.

AIM: Current Italian legislation obliges employers to prevent workers who are occupationally at risk or who perform jobs that may be hazardous for the safety or health of third parties from consuming alcohol. The LaRA Group undertook to assess whether the law fully safeguards the health and safety of both workers and third parties, without impinging upon the civil rights of workers. METHOD: A written document expressing agreement was produced following discussions between doctors, lawyers, bioethicists and social partners. RESULTS: There are gaps and inconsistencies in current laws; the differences in local and regional provisions prevent authorities from applying a single strategy at national level. There should be a change in existing rules under which the employer's obligation to enforce the ban on consumption alcohol in the workplace is enacted solely by the "competent" physician whose institutional role is to safeguard and promote health. Some occupational categories that are subject to a ban on alcohol consumption do not currently under-go health surveillance. For example, if road transport drivers are not exposed to a specific occupational risk foreseen under another law, they can be placed under health surveillance only in those regions where the local laws contemplate this type of control. In other cases, the practice of assessing the risk to third parties and providing for compulsory health surveillance in the Risk Assessment Document, is considered by some jurists to be a "consuetudo praeter legem" and therefore acceptable in a field not yet covered by a specific law, but to be "contra legem" or unlawful by other jurists. Moreover, the competent physician who uses a breathanalyser or tests for alcohol addiction faces an ethical dilemma, since by communicating the results to an employer or authorities responsible for the issuing of licenses, he may be violating his professional oath of secrecy. Furthermore, the emphasis placed on testing has induced companies and inspectors to overlook educational and rehabilitation aspects. It is essential to involve general practitioners, educators and specialist services in addressing the problems of alcohol abuse so as to inform/train, recover and rehabilitate. The few studies available indicate that the rules are poorly enforced and that non-compliance may go unobserved. CONCLUSIONS: The Group urges all employers to assess the risk for third parties caused by alcohol abuse and to devise a policy on alcohol. Controlling alcohol-related risks in the workplace calls for a better definition of the roles of Vigilance Bod-ies and Company Physicians together with a shift from a reactive to a proactive attitude of all the parties involved.

Malnutrition in elderly: social and economic determinants.

UNLABELLED: Malnutrition occurs frequently in the frailest groups of the population, especially in people who are on a low income and elderly subjects, overall if they are institutionalized. The aim of this study was to assess the prevalence of malnutrition in a sample of elderly people living in different settings and to identify the determinants of malnutrition. METHODS: A total of 718 subjects, 472 females (F) and 246 males (M), were recruited from nursing homes or were free living in three different regions in Italy. Nutritional status, depression, social, functional and cognitive status, were evaluated. RESULTS: According to the Mini Nutritional Assessment (MNA), a high prevalence of malnutrition was found out in both genders: 26% of F and 16.3% of M were classified as being malnourished (MNA<17); 40.9% of F and 35% of M were at risk of malnutrition (MNA 17-23,5). The prevalence of malnutrition was significantly higher in NH subjects in both sexes. Moreover, a relationship was shown between malnutrition and inability to shop, prepare and cook meals because of a low income, distance from markets or supermarkets as well as impossibility to drive the car or to use public transportation. This study confirms the necessity to routinely perform nutritional status evaluation in elderly subjects, to carry out training courses for health workers (doctors, nurses, psychologists, dietitians), to implement nutritional education of the geriatric population, to develop tools and guidelines for health workers and caregivers, to identify and reduce clinical, functional, social or economic risk factors for malnutrition.

[Malnutrition in the elderly: clinical features, psychological and social determinants. Preliminary results]. / La malnutrizione in età geriatrica: caratteristiche cliniche e determinanti psico-sociali (MEG). Risultati preliminari.

In industrialized Countries malnutrition is a very frequent condition in frail groups of the population, people with low income and elderly subjects above all if institutionalized. The aim of the study is to: analyse the prevalence of malnutrition in a sample of elderly people located in different geographical areas in Italy; identify the psychological, social, economic, environmental, cultural and demographic determinants of malnutrition. The prevalence of malnutrition (estimated through the MNA) is high in both sexes (28% of F and 21.9% of M. Age, institutionalisation, health status, autonomy status, cognitive status and education level are some of the factors that correlate with the presence of malnutrition. Loneliness and poverty seem to have a negative impact on nutritional status but further data are needed to confirm this hypothesis. The data collected confirm the need to activate services dedicated to assess the nutritional status of elderly people, to implement campaigns in particular on food education for the elderly population, to set tools and guide lines for caregivers.

[Mediterranean diet and prevention of non-communicable diseases: scientific evidences]. / La dieta Mediterranea nella prevenzione delle patologie cronico-degenerative: evidenze scientifiche.

Epidemiological studies showed that the Mediterranean Diet represents a healthy food model in the maintenance of the state of health and in the improvement of the quality of life. The aim of this study was to define the relation between the Mediterranean Diet and the state of health, particularly the role in the prevention of the non-communicable diseases. A systematic literature review was made, analyzing clinical trials published on PubMed from January 2005 to September 2008 and using, separately or in combination, the key words: "Mediterranean Diet", "Health", "Prevention", "Diabetes", "Lipoproteins", "Cardiovascular Diseases", "Cancer." A total of 16 articles were selected. The studies included 101 to 25623 caucasian participants, of both genders, age between 18 and 80 years. Results were analyzed for the effects of the Mediterranean Diet on Cancer; Metabolic Syndrome and Cardiovascular Diseases, in terms of primary and secondary prevention. The Mediterranean Diet showed benefits on the incidence of cancer in healthy subjects, on the metabolic syndrome both in primary prevention that secondary, modifying numerous variables and about cardiovascular diseases, the Mediterranean Diet reduced the risk of relapse and the mortality by acute coronary syndromes and other cardiovascular causes in high risk patients. First of all the Mediterranean Diet must strongly be considered a correlated food model to the style of life, therefore it need further experimental research to validate the effects of Mediterranean Diet on the state of health.

Significant changes of peripheral perfusion and plasma adrenomedullin levels in N-acetylcysteine long term treatment of patients with sclerodermic Raynauds phenomenon.

The unclear pathogenesis of scleroderma vascular lesions makes treatment of Raynaud's phenomenon (RP) in Systemic Sclerosis (SSc) patients very difficult and a new effective treatment is requested. Recently, a powerful antioxidant agent, the N-acetylcysteine (NAC) has been shown to decrease the frequency and severity of RP in SSc patients. Subsequently, using functional infrared imaging, we showed that a single 1-hour NAC infusion in these patients caused a significant increase of skin temperature. The aim of this study was to demonstrate the efficacy of long term therapy with NAC in an open clinical trial evaluating clinical, instrumental and laboratory parameters. Patients started the treatment receiving for two years, from October to May, intravenous NAC infusions of 15 mg/kg per hour each, for 5 consecutive hours, every two weeks. Before and after each infusion, patients underwent both Laser Doppler perfusion Imaging (LDPI) for the evaluation of the digital perfusion and a blood test to ascertain the plasma adrenomedullin (AM) levels. The NAC infusion increased global hands perfusion and induced a significant decreasing of plasma AM concentrations. Side effects were negligible, easy to control and reversible. Reduction of frequency and severity of RP attacks was recorded. In conclusion, NAC seems to act as an effective vasodilatator in the treatment of RP secondary to SSc and, in addition, it induced significant changes in plasma levels of AM, a potent vasodilator endothelial-derived peptide.

[Pregnancy and work]. / Gravidanza e lavoro.

In the last decades there has been an increase of women's presence in the working field. That has been a consequence of the use of an advanced technology, of a different organization of work, of the rules about men/women equality, as wellas of the women's emancipation. As a result women have been exposed to a greater amount of risks both for their health and for their reproductive function. In this work, we highlighted the pathogenic effects resulting from the interaction of different substances present in the working place with the female organism, with special interest in the effects on pregnancy. Furthermore, we laid stress on the rules and on the guidelines that safeguard women's right to work as well as their right to be mothers both at a national and at an european level.
