[Influence of the diagnosis of Hodgkin's disease on the quality of life of cured patients].

Authors present results of an inquiry dealing with familial and socio-professional reinsertion of 130 patients who have been treated for Hodgkin disease. On a family point of view, after treatment, the rate of single people is higher than in general population. Even though one can observe marriages, and feminine sterility is rare, the number of children by married couple remains low. There is no change in rate of house moving. Most of cured patients return to work. This fact is related to duration of treatment, but variations depend essentially of familial situation, kind to work and quality of previous social insurance. For two groups of people risk of unemployement is higher: agricultural labourers who are often dismissed and contractual civil servants who meet with difficulties to be established. Definitive invalidity is rarely conceded by wearied social organisms. Finally cured patients appear most of the time comparable with healthy population. However they meet with important difficulties to get a loan or to contract a life insurance. Premiums are frequently raised and policies restricted. Difficulties are not related to organic sequelae. Cured patients still remain suspicious for their entourage and employer, that bring them about to hide the pathologic episode.

Alcohol consumption among school adolescents in Palma de Mallorca.

AIMS: To describe alcohol consumption of adolescent boys and girls in Palma de Mallorca, and its relationship with physical activity and socio-demographic factors. METHODS: Four hundred and forty five adolescents (171 boys, 274 girls; 14-18 years old) selected from the school census (participation 96%), using two-stage probability sampling were studied. A semi-quantitative food frequency questionnaire was administered and alcohol intake was analysed. Physical activity was computed as a ratio of energy expended in basal metabolic rate. Socio-demographic data were collected, and categorized as gender, mother's level of education, parental occupational status, and mother's region of origin. RESULTS: About 60% of adolescents, 53% of boys and 65% of girls, reported alcohol consumption, which increased with age in boys (91% when they were 18 years old), but remained constant in girls. The adolescents consumed alcohol mainly on weekends; average consumption was four drinks per drinking day, and the most consumed drinks were mild distilled spirits. The mother's educational level and adolescents' physical activity were negatively and significantly related to alcohol consumption, whereas the adolescents from occupational upper-class parents and non Majorcan/Balearic mothers were positively and significantly related to alcohol consumption. CONCLUSIONS: The increased penetration of alcohol into the adolescents' environment may result in misuse of consumption. To give more information to parents and adolescents on considering alcohol to be a drug, and to promote physical activity among adolescents may be contributing factors towards decreased alcohol consumption among the latter age group.

Tissue composition in persistent dietary obesity after early and adulthood overfeeding in the rat.

The objective of this study was to assess the effects of prolonged cafeteria-diet feeding on tissue composition in adult rats comparing those that had been overfed in early life and then in adulthood with a group that was only overfed in adulthood, and to determine whether any alterations were related to the high energy diet per se or to obesity. In addition to following the body weight changes in detail, tissue masses and composition were determined at selected points of this long term dietary experiment. The marked changes in body weight and tissue composition of cafeteria-fed obese rats were sustained for at least 84 days after returning to the standard diet, and the obesity was exaggerated if these animals were pre-exposed to the palatable diet in early life. Three patterns of tissue composition in response to cafeteria feeding could be discerned: Liver and brown adipose tissue developed cell hypertrophy without apparent hyperplasia. In contrast, the retroperitoneal white adipose depot developed hyperplasia whereas the intestine and kidneys were not associated with marked changes in lipid composition. These adaptations were not recovered to control levels by prolonged standard diet feeding. Previous obesity influenced the adaptations in adipose tissue during the subsequent return to standard diet feeding, and differences between cafeteria-induced obese animals became more apparent when the cafeteria diet was removed. These results indicated the important effects of early dietary experience in subsequent responses to overfeeding.

Erythrocyte uptake kinetics and cell to plasma gradients of leucine and phenylalanine in fed and fasted rats.

The kinetic parameters of the L-phenylalanine and L-leucine uptake by isolated erythrocytes in fed and 24 hour starved rats have been determined. In addition, the in vivo compartmentation between blood cells and plasma of the above amino acids in arterial and venous blood vessels has also been studied under the above physiological situations. Both the L-phenylalanine and L-leucine uptake by erythrocytes was saturable and non concentrative. Starvation increased the Km value for the leucine uptake and did not significantly affect that of phenylalanine uptake. The in vivo blood cell/plasma (C/P) concentration ratio of both amino acids was higher than the unit. The starvation-induced changes in the relative distribution of these amino acids between the blood cell and the plasma compartments were significant for the phenylalanine in the aortic artery but not in venous blood. The transport system capabilities measured in vitro can not account for the maintenance of both the leucine and phenylalanine gradient between blood cells and plasma, and the starvation-induced changes in the blood amino acids compartmentation are not directly related entirely to the transport system capabilities.

Dietary intake and nutritional risk among free-living elderly people in Palma de Mallorca.

OBJECTIVE: To describe the dietary intake of free-living, non-institutionalised, elderly people of Palma de Mallorca, and to evaluate their nutritional status and risk of undernutrition. DESIGN: Anthropometric and dietary survey (3-day food record), and risk of undernutrition (MNA-SF) were assessed in 230 (89 men and 141 women) free-living elderly people (average age 72.7 +/- 5.9 years) in Palma de Mallorca. RESULTS: Prevalence of undernutrition (1% in men and 5% in women), overweight (56% in men and 39% in women) and obesity (17% in men and 21% in women) were found. Mean daily energy intake (+/- SD) was 5.7 +/- 1.5 MJ in men and 5.3 +/- 1.3 MJ among women. The contribution of macronutrients to the total energy intake was different from the Recommended Intake for the elderly, since it was too derived from proteins, fats, SFA and sugars, but in only small amounts was derived from complex carbohydrates. Animal protein intake was two-thirds the total protein intake. Dietary fibre was low. Cholesterol/SFA ratio showed dietary risk of atherogenic potential. High percentages of elderly persons showed inadequate intake of calcium, magnesium, zinc, folic acid, vitamin D, and vitamin E. CONCLUSIONS: An increase in dietary complex carbohydrate and fibre, a decrease in fats, especially SFA, and a balanced intake of animal/vegetable proteins and fats are recommended. Dietary supplementation, especially with calcium, vitamin C and E, and occasionally vitamin D, may be useful to improve nutritional and health status of free-living elderly people in Palma de Mallorca.
