Forecasting agriculturally driven global environmental change.

During the next 50 years, which is likely to be the final period of rapid agricultural expansion, demand for food by a wealthier and 50% larger global population will be a major driver of global environmental change. Should past dependences of the global environmental impacts of agriculture on human population and consumption continue, 10(9) hectares of natural ecosystems would be converted to agriculture by 2050. This would be accompanied by 2.4- to 2.7-fold increases in nitrogen- and phosphorus-driven eutrophication of terrestrial, freshwater, and near-shore marine ecosystems, and comparable increases in pesticide use. This eutrophication and habitat destruction would cause unprecedented ecosystem simplification, loss of ecosystem services, and species extinctions. Significant scientific advances and regulatory, technological, and policy changes are needed to control the environmental impacts of agricultural expansion.

[Iron deficiency anemia due to stromal tumor of the ileum].

Iron-deficiency anemia occurs in 3.5 to 5.3% of adult men and postmenopausal women. Occult gastrointestinal bleeding is the cause in the vast majority of cases. After endoscopic examinations have ruled out lesions in colon and upper gastrointestinal tract, 5 to 20% of those patients remain without diagnosis. Angiodysplasias and tumors are the most common causes of occult bleeding arising from the small bowel. Their diagnosis requires complex studies with quite low yield. However, it is necessary to perform them when anemia becomes severe or persistent. We report the case of a male patient with severe and persistent iron-deficiency anemia who had a stromal gastrointestinal tumor located in the ileum.

[Plasma lipoprotein levels in relation to dietary habits].

We carried out a nutritional and haematological survey on 130 pupils of a boarding school in Cagliari in order to determine the relationship between plasma lipoprotein and nutritional habits, particularly, we determined beta/alpha ratio of lipoprotein comparing it with plasma values in hospitalized patients, suffering from metabolic and cardiovascular disease. The results allowed us to observe that 92% of hospitalized patients and 17% of subjects, presumably in good health, showed beta/alpha ratio greater than 2,5. The latter, apparently insignificant, is very important because it was detected in young subjects; as their diet was high-fat and high-carbohydrate, a nutritional and haematological survey will be always necessary in order to prevent illnesses.
