- There is concern over the high risk of cardiovascular complications, hypertensive disorders, and other adverse obstetric outcomes among pregnant women with Turner syndrome (TS). A diagnosis of TS is made in some women late in life or not at all. Spontaneous pregnancies are rare in women with TS and are associated with a high rate of complications, especially miscarriage. The use of assisted reproductive techniques is an option for these women; pregnancy and implantation rates after oocyte donation in women with TS seem to be comparable with those without TS who need this treatment. Few data are available on obstetric outcome in pregnant women with TS. The aim of this retrospective population-based cohort study was to compare maternal and neonatal outcomes among singleton pregnancies of women with and without TS. Data on births occurring between 1973 and 2007 from the Swedish Genetic Turner Register and the Swedish Medical Birth Register were cross-linked. Obstetric outcome in infants born to women with TS was compared with a reference group of 56,000 women from the general population. Mean gestational age and birth weight were adjusted for maternal age. Outcome in TS women with twins was described separately. A total of 115 women with TS gave birth to 208 children (202 singletons and 3 sets of twins) during the study period. The TS diagnosis was unknown in 52% of the women before the first delivery. Women in the TS group were older at the first delivery than women in the reference group; median age was 30 years and 26 years, respectively (P < 0.0001). There was a trend toward more women with TS having preeclampsia during their first pregnancy (6.3 vs. 3.0%; P = 0.07). One woman suffered from an aortic dissection during her second spontaneous pregnancy. Compared with the reference group, the median gestational age was shorter in children in the TS group (-6.4 days, P = 0.0067), and median birth weight was lower (-208 g, P = 0.001); however, no significant difference was found in median standard deviation scores for weight and length at birth. The rate of cesarean delivery was higher in the TS group than in the reference group (35.6% vs. 11.8%, respectively, P < 0.0001). There was no significant difference in birth defects between groups. These findings show that women with a TS karyotype have mostly favorable obstetric outcomes. Singletons of women with TS have a shorter gestational age but a similar size at birth. The data also show no difference in birth defects between women with and without TS.

- In Sweden a multicentre nutritional survey was performed in 1980-81 in four different parts of Sweden. The total number of children investigated was 1109, of whom 92 were two years old, 332 four years, 338 eight years and 347 thirteen years. The 24-hour recall method was used in all children. In addition 7-day record was used in the 2-, 4- and 8-year-olds and the dietary history method in the 13-year-olds. During the weekdays the 2-, 4-, 8- and 13-year-old children had 5.9, 5.8, 5.4 and 5.2 meals and snacks per day, respectively. During weekends these respective numbers decreased to 5.7, 5.6, 5.1 and 5.0. The mean number of light meals and snacks was almost the same on all days and varied between 2.4 and 3.3 in the different age groups. The part of the energy intake deriving from snacks has increased during the last 15 years. The mean daily energy intakes for the 2-, 4-, 8- and 13-year-old boys and girls were 5.8 and 5.6, 6.9 and 6.5, 8.9 and 7.9 and 12.1 and 9.7 MJ respectively. These values are below the recommendations for all age groups except the 2-year-old boys. The mean daily intakes of protein, retinol, ascorbic acid, thiamin, riboflavin, niacin, vitamin B12 and calcium were almost invariably higher or much higher than the recommendations, while those of vitamin D and zinc were below the recommended values. The iron intake fulfilled the recommendations except for the 2-year-olds and the 13-year-old girls. The intake of protein and fat expressed in per cent of the total energy intake was very similar in all age groups, about 14 per cent and 35-37 per cent respectively. The mean ratio between polyunsaturated and saturated fatty acids (P/S ratio) was also the same in all age groups, i.e. 0.22-0.23. This low ratio is explained by a high consumption of dairy products. Furthermore, the nutrient density of the food did not change appreciably with age. The only exception was found for the 2-year-old children, who had slightly higher nutrient density values on account of a relatively high consumption of fortified follow-up formula. In all age groups the mean nutrient densities of vitamins D and B6 and of iron were below the recommendations to varying degrees. No clinical signs of nutritional deficiencies, iron deficiency included, were found in any age group.(ABSTRACT TRUNCATED AT 400 WORDS)

- The role of complement in biocompatibility reactions and the correlation between complement activation during cardiopulmonary bypass (CPB) and postperfusion syndrome have inspired attempts to improve the biocompatibility of extracorporeal blood oxygenation devices. Here we assessed the effect of immobilized heparin on the generation of C3a and terminal complement complexes during CPB. Thirty patients undergoing aortocoronary bypass were randomized to CPB with either heparin-coated (Duraflo II; Bentley, Irvine, CA) or noncoated control membrane oxygenators (Univox; Bentley). A standard dose of heparin (300 IU/kg) was given to the control group while the heparin dose was reduced to 30% (100 IU/kg) in the heparin-coated group. Significantly lower levels of terminal complement complexes were detected in the heparin-coated group by the end of CPB. From 28 +/- 5 AU/mL (heparin-coated group) and 26 +/- 3 AU/mL (control group, mean +/- standard error of the mean) the terminal complement complex levels increased to 391 +/- 35 AU/mL and 602 +/- 47 AU/mL, respectively (p < 0.002). This difference was still apparent 180 minutes after CPB. Although there was no difference in C3a levels between the two groups at the end of CPB, C3a levels were significantly lower in the heparin-coated group 30 minutes after CPB (194 +/- 18 ng/mL and 307 +/- 18 ng/mL in heparin-coated and control groups, respectively; p < 0.001). We conclude that the heparin-coated surface is more biocompatible with regard to complement activation than is the ordinary unmodified surface in extracorporeal circuits.

- To study the magnitude of agreement between a short self-administered food frequency questionnaire and a 7-day weighed dietary record regarding the consumption of fibre and fat, we collected information from 92 randomly selected middle-aged Swedish men. The participants first recorded all foods and drinks consumed over seven consecutive days by means of a digital scale. One month after the 7-day weighed record had been completed, a self-administered food frequency questionnaire on habitual consumption of foods containing fibre or fat during the preceding month was sent to the subjects. The 20 largest contributors of fibre and fat in the diet accounted for 71% and 52% of the total intake, respectively, based on the 7-day weighed record. The estimated mean consumption of fibre was 19.0 grams per day based on the 7-day weighed record and 18.3 grams per day based on the food frequency questionnaire. Corresponding estimated mean consumption of fat was 88.6 grams per day versus 46.9 grams per day. Men with high physical activity and low BMI, respectively, had higher intake of fibre and fat. These differences were seen for both dietary measurement methods but were more marked using the 7-day weighed record. The agreement between methods for each individual was also assessed. Based on five categories of fibre consumption, 61% of the respondents in the highest quintile according to the 7-day weighed record were classified in one of the two highest quintiles according to the food frequency questionnaire. The corresponding figure for fat intake was 56%. We conclude that the short self-administered food frequency questionnaire used in the present study can assess the absolute intake of fibre, but not of fat, with good precision. Also, the ranking of indiviudals in broad categories of consumption of fibre and fat was not largely misclassified based on this short questionnaire.

Tidskriftsartikel (refereegranskat)abstract
- A random sample of 682 8- and 13-year-old children resident in Sweden was studied with regard to physical activity, energy intake, height, weight and skinfold thickness. A reduction of physical activity over the years was indicated by a tendency towards a higher body fat content in spite of a lower mean energy intake as compared with such values obtained 10-15 years ago in Swedish children of equal ages. Children characterized by high habitual physical activity tended to have a lower body fat content, despite a higher energy intake, than less active children. Children, especially girls, of parents with a low educational level showed a tendency towards higher body fat content as compared with those of parents with higher education.
