Trends in meningococcal disease in Italy in 1988

Meningococcal disease in Italy decreased 15% in 1988 from the previous year (290 vs. 342 cases). The decline was particularly evident in military cases (1.7/100,000 in 1988 vs. 5/100,000 in 1987) reflecting the full coverage of bivalent serogroup (A + C) meningococcal polysaccaride vaccine in army recruits, achieved since January 1988. The highest proportion of cases was seen in people older than 25 years of age (25%). Serogroup C constituted 60% of the isolates, while 19% belonged to serogroup B. The proportion of strains resistant to sulphonamides was 45%, while 15% were resistant to Minocycline and none to Rifampin. Out of the five military cases, only one (due to serogroup C) was attributable to the vaccine failure. A single coprimary case, but no secondary cases occurred among civilians. These findings are consistent with the trends reported in Italy in the previous years.     

Benzene in blood and phenol in urine in monitoring benzene exposure in industry

Determinations of benzene concentration in blood and of phenol in urine were made by head-space gas chromatography techniques on samples taken near the end of the work day from two groups of workers potentially exposed to low levels of benzene in the work-place atmosphere. Preliminary results suggest that benzene in blood is more reliable than phenol tests for assessing both exposure and uptake of benzene. Normal values of phenol in urine (10 mg/liter or less) were found in nearly all those cases in which benzene was detected in the blood.

Occupational stress in nurses in psychiatric institutions in Taiwan

Nurses are known to be exposed to occupational stress. However, occupational stress is not well documented for nurses in psychiatric institutions in Taiwan. A cross-sectional study was conducted to explore the work-related stress and risk factors of nurses in psychiatric institutions in Taiwan. A structured questionnaire was distributed to nurses at five state-owned psychiatric hospitals in Taiwan in 2001. Demographic information, working environment, and personal health status were inquired. Occupational stress was assessed based on the Chinese version of Job Content Questionnaire (JCQ). General health status and mental health were evaluated by the International Quality of Life Assessment Short Form-36 (IQOLA SF-36). A total of 573 questionnaires were disseminated to nurses and 518 (90.4%) were satisfactorily completed by nurses, including 408 female full-time nurses who had been in their current work for more than 6 months. In the past one month, 17.2% of nurses reported being under significant stress often or always. Assault episodes were reported by 45.1% of nurses in the past 6 months. Among the nurses, 16.9%, 25.2%, 50.0%, and 7.8% belong to the "High strain", "Low strain", "Active", and "Passive" groups, respectively. Perceived occupational stress was associated with young age, widowed/divorced/separated marital status, high psychological demand, low workplace support, and threat of assault at work. Lower general health score was associated with low job control, high psychological demand, and perceived occupational stress. A lower mental health score was associated with low job control, high psychological demand, low workplace support, and perceived occupational stress. We concluded that nurses in psychiatric institutions are under significant stress related to work factors.     

Changes in nursing administration in supporting transplantation in Brazil

This historical and bibliographic study aimed to understand how Nursing was organized to support care in transplantation. The HISA, LILACS, BDENF, PERIENF and DEDALUS databases were consulted, and thirteen references were found, ten of which were scientific articles, two were master's dissertations and one was a doctoral thesis. The span of time chosen for study ranges from the date of the first kidney transplant in Brazil (1965), to the date of publication of the last scientific article found in the databases mentioned above (2003). After reading these articles, the ones that were similar in topic were grouped together, thus creating the thematic axis for the presentation of the results. The results showed that the Nursing profession has played an important and active role in transplants ever since the first procedure in 1965.     

Trends in changes in plant fiber consumption in Poland

The purpose of the study was an analysis of changes in the consumption of plant fibre in Poland in the period 1950-1987. The analysis included plant fibre content in four groups of products considered as the main source of fibre in diet: cereals, potatoes, vegetables and fruit. A reduction was noted in the consumption of plant fibre in general, and the fibre present in cereals and potatoes, while that present in fruit and vegetables has increased. The pattern of plant fibre consumption in Poland is becoming ever more similar to that in highly developed countries. Systematic studies are proposed on the consumption of plant fibre by various groups of the population. It would be indicated to explain to the population the importance and role of plant fibre and introduction for marketing of food providing this fibre, in the first place increased supply of brown bread.     

Changes in immune function in asthma in the elderly

Asthma is an inflammatory disorder of the airway. The airway inflammation of asthma is typically an allergic inflammation characterized by cells and mediators described as a "Th2" inflammatory response. There is a growing body of evidence describing changes in the function of immune cells upon aging, a phenomenon referred to as "immunosenescence". Several studies utilizing animal models and human subjects with asthma have begun to explore age-related effects on the airway inflammation in asthma. This review explores the existing data on the presence and effects of immunosenescence or age-related changes in immune function in asthma.     

Changes in Fatty Acid Composition in Beef in Italy

Results from a study conducted in Italy concerning the updating of composition data of beef consumed in Italy are reported here. The study required a very wide sampling plan with regard to both animals and cuts to analyse. Data related to lipid composition of the most widely used type of beef consumed in Italy (young bull, 16–22 months old) show a reduction in total lipid content (which, according to the cuts, ranges between 1.8 and 10.2%) and a substantial change in fatty acid composition, with a high % of polyunsaturated fatty acids (mean 20% of total fatty acids). Such data have been confirmed by other studies conducted in Italy, and are in contrast with data reported in the tables of food composition from other countries, reporting a fatty acid composition characterized by a high fatty acid saturation degree. The occurrence of long-chain polyunsaturated fatty acid is probably due to the high ratio of phospholipids: triglycerides, occurring when the content in intramuscular lipid is very low; to the young age of animals; to the reduced activity of the rumen, where saturation of fatty acids occurs. It may be concluded that a fatty acid composition, which is particularly rich in polyunsaturated fatty acids, seems typical for Italian products.     

Increase in social inequality in health expectancy in Denmark

AIMS: Health expectancy represents the average lifetime in various states of health and differs among social groups. The purpose of the study was to determine trends in social inequality in health expectancy since 1994 between groups with high, medium and low educational levels in Denmark. METHODS: The study was based on data from nationwide registers on educational level and mortality during the period 1994-2005 and data on health status derived from the Danish Health Interview Surveys carried out in 1994, 2000 and 2005. Expected lifetime in self-rated good and poor health, lifetime without and with longstanding illness and expected lifetime without and with long-lasting difficulties or restrictions were estimated by Sullivan's method. RESULTS: Between 1994 and 2005, life expectancy at age 30 years increased by 1.9 years for men and 1.5 years for women with a low educational level. For people with a high educational level, the increase was 2.7 years for men and 2.2 years for women. The difference between people with low and high educational level in expected lifetime in self-rated good health increased by 2.0 and 1.3 years for 30-year-old men and women, respectively. The social gap also increased for other indicators. CONCLUSIONS: During the past 12 years, social inequality in life expectancy and health expectancy has increased in Denmark, but the proportion of the population with a low educational level has decreased.

Botulism in Poland in 2001

A total of 66 cases of botulism (foodborne) were registered in Poland in 2001, with corresponding incidence 0.17 per 100,000 population. The majority of cases (77.3%) were registered in rural areas. Incidence in these areas was 0.35 and in urban areas--0.06. In 2001 there were 41 outbreaks of one person noted, 4 outbreaks of two people, 4 outbreaks of three, and 1 outbreak of four people. Meat dishes were the main vehicle of botulinum toxin (32 cases; 48.5%). Out of them, home made conserves (bottling jars) prepared from pork meat prevailed (25.8% of the total). Home made sausages were associated with 12.1% cases, commercial canned fish--with 10.6% and other dishes from fish--with 12.1%. Two deaths from foodborne botulism were registered in Poland in 2001.
