Globalization and health: results and options.

The last two decades have witnessed the emergence and consolidation of an economic paradigm which emphasizes domestic deregulation and the removal of barriers to international trade and finance. If properly managed, such an approach can lead to perceptible gains in health status. Where markets are non-exclusionary, regulatory institutions strong and safety nets in place, globalization enhances the performance of countries with a good human and physical infrastructure but narrow domestic markets. Health gains in China, Costa Rica, the East Asian "tiger economies" and Viet Nam can be attributed in part to their growing access to global markets, savings and technology. However, for most of the remaining countries, many of them in Africa, Latin America and Eastern Europe, globalization has not lived up to its promises due to a combination of poor domestic conditions, an unequal distribution of foreign investments and the imposition of new conditions further limiting the access of their exports to the OECD markets. In these developing countries, the last twenty years have brought about a slow, unstable and unequal pattern of growth and stagnation in health indicators. Autarky is not the answer to this situation, but neither is premature, unconditional and unselective globalization. Further unilateral liberalization is unlikely to help them to improve their economic performance and health conditions. For them, a gradual and selective integration into the world economy linked to the removal of asymmetries in global markets and to the creation of democratic institutions of global governance is preferable to instant globalization.

Effect of dietary oils containing different amounts of precursor and derivative fatty acids on prostaglandin E2 synthesis in liver, kidney and lung of rats.

The availability of the fatty acids which are precursors of prostaglandins is affected by dietary intake. We have studied, in particular, the effects of dietary intake of lipids with different amounts of precursor and derivative fatty acids on the synthesis of prostaglandin E2 (PGE2) in rat liver, kidney and lung. Fifteen-month-old rats were fed for 3 months diets containing different amounts of oleic, linoleic, alpha linolenic, gamma linolenic and stearidonic acids. The fatty acid compositions of total phospholipids and prostaglandin E2 levels of liver, kidney and lung were investigated. In the organs studied, the intake of lipids at different amount of precursor/derivative fatty acids caused variations in the fatty acid composition of phospholipids. PGE2 showed different values which did not seem directly affected by tissue availability of arachidonate but by the effect of dietary lipids on the metabolic pool of polyunsaturated fatty acids (PUFAs).

Calculating the economic impact of healthcare facilities on communities.

A methodology has been developed to calculate the direct, indirect, and induced spending effects of a healthcare facility on the community it serves. This methodology may be used by financial managers to produce data that demonstrate the effect of facilities on local economies. The data may be used by administrators to increase awareness of the pivotal economic role healthcare facilities play in communities among business and government leaders, economic development organizations, medical staff members, facility employees, trustees, and patients.

The role of community hospitals in the performance of local economies.

Many hospital administrators recognize an increasing need to educate the public on the important role their institutions play in the economic viability of the local community. Reasons include negative coverage by the press of increasing hospital costs, eroding philanthropy, managed care programs mandating out-of-area preferred providers, and declining city revenues, which have caused some municipalities to attempt to place not-for-profit health care facilities on the tax roles. This article reviews a technique that can be used by hospitals to build community support by demonstrating the favorable economic impact hospitals have on the communities they serve.

The economic impact of hospitals in rural communities.

This article presents how to assess the economic impact of a hospital on a rural community. The economic impact is identified by assessing the direct, induced, and indirect impacts that result because of the presence of a hospital in a rural community. The methodology utilizes survey data and estimation procedures for four rural hospitals. The economic impact estimates are based on microdata. Income multipliers are estimated for each of the rural communities. The research demonstrates that rural hospitals do make significant economic contributions to the communities they serve. Community leaders can use the model presented to evaluate the economic impact of their local hospital.

Property tax exemption for nonprofit hospitals.

This article discusses management practices that hospital administrators can use to minimize the exposure to property taxation. First, the results of a national survey on the extensiveness of property tax exemption are reviewed. Next, a review of the history of recent developments in Utah is presented, including the recent ruling of the Utah State Supreme Court that "nonprofit" status does not necessarily qualify a hospital for property tax exemption. Finally, a series of suggestions for nonprofit hospitals to consider in an effort to minimize the probability of a challenge to their tax-exempt status is offered.

Lactose malabsorption in adult patients with Crohn's disease.

In order to evaluate, in adult patients with Crohn's disease (CD), the prevalence of lactose malabsorption and intolerance, and the percentage who can tolerate a physiologic amount of milk in their diet, we tested 37 patients with CD (19 with intestinal resection, and 18 without) and 67 healthy controls (C) with the H2-breath test after they had ingested increasing loads of lactose as 10% solution (12.5 g, 25 g, and 50 g). Patients with malabsorption after the 12.5-g dose were tested further with 250 ml of milk. In the total group of patients and in the subgroup of those with resection, the prevalence of malabsorption was higher than in controls at all lactose loads; in patients who had not undergone resection, no significant difference was observed with the 12.5-g dose. Eleven of 18 patients who were malabsorbers with the 12.5-g dose had malabsorption also with 250 ml milk; however, only three of them (8% of the total group) experienced symptoms of intolerance. We conclude that, in adult patients with CD, 1) the prevalence of lactose malabsorption is increased, 2) in patients who have undergone intestinal resection, malabsorption occurs at a lower dose of the sugar than in patients who did not, and 3) since only 8% of patients experienced symptoms of intolerance after the ingestion of milk 250 ml, this amount can be empirically inserted in the daily diet of an adult with CD.

Evaluation of oral administration of folic and folinic acid to prevent folate deficiency in patients with inflammatory bowel disease treated with salicylazosulfapyridine.

In order to evaluate the efficacy of oral administration of a pharmacological dose of folic or of folinic acid to prevent the folate deficiency in patients with inflammatory bowel disease (IBD) treated with salicylazosulfapyridine (SASP) (1g twice daily at meal times), two groups of 15 patients with IBD received 15 mg/day of folic or folinic acid for one month. In both the groups there were ten patients affected by Crohn's disease and five patients affected by ulcerative colitis. Before starting the treatment, the plasma folate and the red blood cell (RBC) folate concentrations did not statistically differ between the two groups. After one month the mean increase in RBC folate concentration was significantly greater after folinic therapy then after folic acid therapy (910 +/- 383 versus 570 +/- 212 ng/ml; p less than 0.01), while no difference was observed in the mean increase of plasma folate level (19.8 +/- 6.6 versus 18.5 +/- 5.0 ng/ml). It was concluded that: a) both folic and folinic acid could restore and enlarge the body stores of folate in patients with IBD treated with SASP, when administered at the dose of 15 mg daily for one month; b) folinic acid seems to be more efficient in enlarging the body stores of the vitamin than folic acid.

Optimal nutritional indexes in gastroenterology.

Malnutrition in gastrointestinal disease can result from several pathogenetic mechanisms. The resulting clinical and laboratory features of malnutrition vary according to the specific pathogenetic factors involved. Many of the causes of malnutrition in gastroenterology are similar to those found in other acute and chronic diseases. However, certain disorders, specific to gastroenterology, may alter nutritional indices independent of the usual causes of malnutrition. These include small bowel bacterial overgrowth and protein-losing enteropathy. The impact of these disorders on the indexes of nutritional status is discussed.

Urinary zinc excretion in Crohn's disease.

In order to study the reliability of urinary zinc levels as an index of zinc metabolism and status in Crohn's disease, we evaluated plasma and urinary zinc concentrations, urinary 3-methylhistidine excretion, and Crohn's disease activity index (CDAI) in 42 patients affected by Crohn's disease. Plasma zinc correlated directly with albuminemia (P = 0.01) and inversely with CDAI (P = 0.001). Urinary zinc excretion correlated with urinary 3-methylhistidine (P = 0.001) and plasma zinc levels (P = 0.01), and inversely with CDAI (P = 0.05). However, from multiple regression analysis, it was found that zincemia is influenced by CDAI and not by albumin, whereas zincuria is related to urinary 3-methylhistidine and plasma zinc, and not to CDAI. Our conclusion is that, in Crohn's disease, zincuria can be an index of zinc status when used together with measurements of lean body mass and turnover and factors influencing plasma ultrafiltrable zinc fraction.

Effect of chemically defined formula diets on pancreatic mass in the rat.

To establish the effect of chemically defined formula diets on pancreatic mass, 58 male Wistar rats, weighing approximately 200 g, were fed orally one of the following diets for 20 days: standard diet; partially hydrolyzed diet; elemental diet. The diets were isocaloric and provided 73 cal/day per rat. At the end of the experiment, the rats were killed and pancreas removed to assess wet weight and DNA and RNA content. Compared to the controls, the elemental diet caused a reduction in pancreatic wet weight (p less than 0.005), pancreatic DNA (p less than 0.001), and RNA content (p less than 0.001). In the group fed partially hydrolyzed diet, only pancreatic DNA content showed an highly significant reduction when compared with the reference group (p less than 0.001), whereas the value of RNA failed to reach the statistical significance. We found an increase of the ratio mg RNA/mg DNA in the partially hydrolyzed and elemental diet groups. These results suggest that long-term nutrition with the partially hydrolyzed diet, and more strongly with the elemental diet, may induce pancreatic hypoplasia.

Gastric inhibitory polypeptide release after oral glucose: relationship to glucose intolerance, diabetes mellitus, and obesity.

Hypersecretion of immunoreactive gastric inhibitory polypeptide (IRGIP) has been reported previously in patients with diabetes mellitus (DM) and obesity. To ascertain the relative contribution of glucose intolerance and obesity to the abnormalities of IRGIP secretion, 114 subjects were studied during a standard oral glucose (75 g) tolerance test; responses of glucose, insulin, C-peptide, IRGIP, and glucagon were evaluated. The subjects were divided into six subgroups according to body weight and the degree of glucose intolerance. In normal weight subjects, the IRGIP response to oral glucose was significantly higher in the patients with impaired glucose tolerance (IGT) and DM than in the healthy control subjects (P less than 0.05). In the obese subjects, no significant differences in mean IRGIP responses could be detected among control, IGT, and DM subjects. In spite of similar IRGIP responses, the obese IGT patients did release more insulin than the obese control subjects, suggesting that incretin factors other than GIP may be operative in this condition. When obese and nonobese patients were compared, the obese subjects with normal glucose tolerance released a greater amount of IRGIP and insulin than the normal weight controls, whereas no significant difference between obese and nonobese could be found within the IGT and DM groups. We conclude that in the absence of obesity, glucose intolerance may induce IRGIP hypersecretion. On the other hand, obesity is associated with IRGIP hypersecretion, and glucose intolerance has no further effect, indicating a different pathogenetic mechanism for the IRGIP abnormalities. In both the obese and nonobese diabetic groups, IRGIP hypersecretion was associated with a failure of plasma glucagon levels to fall after oral glucose; this effect might be related to the glucagonotropic action of this peptide.

[Asthma as a psychosomatic disease and its treatment with tranquilizing agents]. / A proposito dell'asma come malattia psicosomatica e del suo trattamento con psicofarmaci

On the basis of personal research and experience, it is concluded that the majority of asthmatics also suffer from psychoneurosis and that psychological alterations are primary and not secondary to dyspnoea. Some hypotheses are put forward relating the onset of asthma and psychoneurosis.

[The place of citicolin in pulmonological therapy (author's transl)]. / Citicolin in der pulmonologischen Therapie

Citicolin, a psychodrug, is usually used for the treatment of ischemic cerebropathies. Its introduction into pulmonological therapy is suggested because Citicolin has the following properties: 1. Prevention of "acute respiratory distress syndrome" in neonates. 2. Improvement of chronic respiratory insufficiency. 3. Prevention of postoperative hypoventilation syndrome. 4. Improvment of respiratoy mechanics in syndromes with hyperelasticity of the lungs. 5. Recovery of permeability of the alveolo-capillary barrier for gases. 6. Compensation of the loss of surface-active substances after endobronchial aspiration of intubated patients.
