RESUMEN
The composition of human breast milk changes in the first two months of life, adapting itself to the evolving needs of the growing new-born. Lipids in milk are a source of energy, essential fatty acids (FA), fat-soluble vitamins, and vital bioactive components. Information on breast milk FA of Malaysian lactating women is scarce. Based on convenience sampling, a total of 20 Malay breastfeeding women who fulfilled the inclusion criteria were recruited. Breast milk was collected three times from each subject at consecutive intervals of 2-3 weeks apart. A total of 60 breast milk samples were collected and classified into "transitional milk" (n = 8), "early milk" (n = 26) and "mature milk" (n = 26). All milk samples were air freighted to University of Groningen, Netherlands for analysis. The dominant breast milk FA were oleic acid, constituting 33% of total fatty acids, followed by palmitic acid (26%). Both these FA and the essential FA, linoleic acid (10%) and alpha-linolenic acid (0.4%), showed no significant changes from transitional to mature milk. Breast milk ratio of n-6:n-3 polyunsaturated fatty acids (PUFA) was comparatively high, exceeding 10 throughout the lactation period, suggesting a healthier balance of PUFA intake is needed in pregnancy and at postpartum.

BACKGROUND: Iodine deficiency occurs in West European countries. Iodine is important for brain development of the foetus and infant. The current iodine status of pregnant and lactating Dutch women is unknown. METHODS: In a pilot study we examined the iodine status of 36 women. From 20 gestational weeks (GW) until 4 weeks postpartum, they ingested 150 µg iodine/day in the form of a multivitamin supplement for pregnant and lactating women. Twenty-four hour urine samples were collected at 20 and 36 GW and at 4 weeks postpartum. A breast milk sample was collected at 4 weeks postpartum. Iodine concentrations were analysed by inductively coupled plasma-mass spectrometry. Cut-off values for the urinary iodine concentration (UIC) for pregnant and lactating women are 150 and 100 µg/l, respectively. Adequate intakes (AI) of iodine for infants aged 0-6 months are 1.1 µmol/l (Institute of Medicine recommendations) or 0.5 µmol/l (Nordic Councilrecommendations). RESULTS: The median UICs (percentages below cut-off) were 102 µg/l (83%) at 20 GW, 144 µg/l (56%) at 36 GW and 112 µg/l (40%) at 4 weeks postpartum. The median breast milk iodine concentration was 1.2 µmol/l (range 0.5-3.0); 33% and 0% of the infants had estimated iodine intakes below the IOM-AI and Nordic-AI, respectively. CONCLUSION: This pilot study suggested a high prevalence of iodine deficiency during pregnancy. Daily supplementation of 150 µg iodine from 20 GW might be insufficient to reach maternal iodine adequacy. The median breast milk iodine concentration seems adequate. Further studies, using a representative sample of the Dutch population, are needed to establish the current Dutch iodine status of pregnant and lactating women.

INTRODUCTION: Erythrocyte (RBC) DHA+EPA is considered optimal at 8g%. Mothers with lifetime high fish intakes exhibiting this status produce milk with about 1g% DHA+EPA. We established DHA+EPA supplemental dosages needed to augment RBC DHA+EPA to 8g% and milk DHA+EPA to 1g%. MATERIALS AND METHODS: Pregnant women were randomly allocated to DHA+EPA dosages of: 225+90 (n=9), 450+180 (n=9), 675+270 (n=11) and 900+360 (n=7) mg/day. Samples were collected at 20 and 36 gestational weeks and 4 weeks postpartum. RESULTS: Linear regression revealed needed dosages rounded at 750mg/day to reach 8g% RBC DHA+EPA and 1000mg/day for 1g% milk DHA+EPA. RBC DHA+EPA increment depended on baseline values. There was no effect on milk AA, but milk EPA/AA ratio increased. CONCLUSION: Women with an RBC DHA+EPA status of 5.5g% need 750 and 1000mg DHA+EPA/day to reach 8g% RBC DHA+EPA at the pregnancy end and 1g% mature milk DHA+EPA, respectively.

CHD may ensue from chronic systemic low-grade inflammation. Diet is a modifiable risk factor for both, and its optimisation may reduce post-operative mortality, atrial fibrillation and cognitive decline. In the present study, we investigated the usual dietary intakes of patients undergoing elective coronary artery bypass grafting (CABG), emphasising on food groups and nutrients with putative roles in the inflammatory/anti-inflammatory balance. From November 2012 to April 2013, we approached ninety-three consecutive patients (80% men) undergoing elective CABG. Of these, fifty-five were finally included (84% men, median age 69 years; range 46-84 years). The median BMI was 27 (range 18-36) kg/m(2). The dietary intake items were fruits (median 181 g/d; range 0-433 g/d), vegetables (median 115 g/d; range 0-303 g/d), dietary fibre (median 22 g/d; range 9-45 g/d), EPA+DHA (median 0.14 g/d; range 0.01-1.06 g/d), vitamin D (median 4.9 µg/d; range 1.9-11.2 µg/d), saturated fat (median 13.1% of energy (E%); range 9-23 E%) and linoleic acid (LA; median 6.3 E%; range 1.9-11.3 E%). The percentages of patients with dietary intakes below recommendations were 62% (fruits; recommendation 200 g/d), 87 % (vegetables; recommendation 150-200 g/d), 73% (dietary fibre; recommendation 30-45 g/d), 91% (EPA+DHA; recommendation 0.45 g/d), 98% (vitamin D; recommendation 10-20 µg/d) and 13% (LA; recommendation 5-10 E%). The percentages of patients with dietary intakes above recommendations were 95% (saturated fat; recommendation < 10 E%) and 7% (LA). The dietary intakes of patients proved comparable with the average nutritional intake of the age- and sex-matched healthy Dutch population. These unbalanced pre-operative diets may put them at risk of unfavourable surgical outcomes, since they promote a pro-inflammatory state. We conclude that there is an urgent need for intervention trials aiming at rapid improvement of their diets to reduce peri-operative risks.

The dietary intake of saturated fatty acids (SAFA) is associated with a modest increase in serum total cholesterol, but not with cardiovascular disease (CVD). Replacing dietary SAFA with carbohydrates (CHO), notably those with a high glycaemic index, is associated with an increase in CVD risk in observational cohorts, while replacing SAFA with polyunsaturated fatty acids (PUFA) is associated with reduced CVD risk. However, replacing a combination of SAFA and trans-fatty acids with n-6 PUFA (notably linoleic acid) in controlled trials showed no indication of benefit and a signal toward increased coronary heart disease risk, suggesting that n-3 PUFA may be responsible for the protective association between total PUFA and CVD. High CHO intakes stimulate hepatic SAFA synthesis and conservation of dietary SAFA . Hepatic de novo lipogenesis from CHO is also stimulated during eucaloric dietary substitution of SAFA by CHO with high glycaemic index in normo-insulinaemic subjects and during hypocaloric high-CHO/low-fat diets in subjects with the metabolic syndrome. The accumulation of SAFA stimulates chronic systemic low-grade inflammation through its mimicking of bacterial lipopolysaccharides and÷or the induction of other pro-inflammatory stimuli. The resulting systemic low-grade inflammation promotes insulin resistance, reallocation of energy-rich substrates and atherogenic dyslipidaemia that concertedly give rise to increased CVD risk. We conclude that avoidance of SAFA accumulation by reducing the intake of CHO with high glycaemic index is more effective in the prevention of CVD than reducing SAFA intake per se.

We showed that docosahexaenoic acid (DHA) supplementation during pregnancy and lactation was associated with more mildly abnormal (MA) general movements (GMs) in the infants. Since this finding was unexpected and inter-individual DHA intakes are highly variable, we explored the relationship between GM quality and erythrocyte DHA, arachidonic acid (AA), DHA/AA and Mead acid in 57 infants of this trial. MA GMs were inversely related to AA, associated with Mead acid, and associated with DHA/AA in a U-shaped manner. These relationships may indicate dependence of newborn AA status on synthesis from linoleic acid. This becomes restricted during the intrauterine period by abundant de novo synthesis of oleic and Mead acids from glucose, consistent with reduced insulin sensitivity during the third trimester. The descending part of the U-shaped relation between MA GMs and DHA/AA probably indicates DHA shortage next to AA shortage. The ascending part may reflect a different developmental trajectory that is not necessarily unfavorable.

BACKGROUND: The decrease of maternal docosahexaenoic (DHA) status during pregnancy has been associated with postpartum depression, especially in women with a low intake of DHA. Since the DHA intake in the Netherlands is low, we investigated whether supplementation of low doses of DHA or DHA plus arachidonic acid (AA) during pregnancy and lactation could prevent depressive symptoms and sleep disturbances in this period. METHODS: Women were supplemented daily with placebo, DHA (220 mg) or DHA+AA (220 mg each) from week 16 of pregnancy till three months postpartum. Fatty acid analyses were performed in the available plasma samples at 16 and 36 weeks of pregnancy. Depressive symptoms were measured in weeks 16 and 36 of pregnancy and six weeks postpartum using EPDS and within one week postpartum using a blues questionnaire. RESULTS: 119 women completed the study. The average frequency of fish intake was low, 0.94 times per week, and did not differ between the groups. The supplementation groups did not differ in mean EPDS scores or changes in EPDS scores, nor in incidence or severity of postpartum blues. Red blood cell DHA, AA and DHA/AA ratio did not correlate with EPDS or blues scores. Indices of sleep quality did not differ between the groups. CONCLUSION: Supplementation of 220 mg/day DHA or DHA+AA (220 mg/day each) does not prevent peri-partum depressive symptoms, in a population based sample with low background DHA intake.

OBJECTIVE: To estimate the incidence of Sickle-Cell Disease (SCD) in Aruba and St. Maarten and to determine whether universal screening would be cost-effective according to United Kingdom criteria. METHODS: Consecutive cord blood samples were collected in Aruba and the Dutch part of St. Maarten during 3 and 4 months, respectively. Samples were subjected to High Performance Liquid Chromatography (HPLC) screening of haemoglobin variants. RESULTS: Of the 368 samples (87.6% of all registered births) collected in Aruba, 10 (2.72%; CI 1.3, 4.9%) tested heterozygous for the Sickle-cell gene (HbAS) and 7 (1.90%; CI 0.8, 3.9%) for the haemoglobin C gene (HbAC). Of the 193 samples (83.5%) collected in St. Maarten, 14 (7.25%; CI 4.0, 11.9%) contained HbAS and 10 (5.18%; CI 2.5, 9.3%) HbAC. Hardy-Weinberg equilibrium predicted an incidence of 2.65% for HbAS and 1.86% for HbAC in Aruba and 6.80% for HbAS and 4.86% for HbAC in St. Maarten. These figures imply a newborn rate of about 2 SCD patients per 3 years in Aruba and 2 SCD patients per year in St. Maarten. CONCLUSIONS: Universal screening of newborns for SCD seems cost-effective for St. Maarten.

AIM: Previously, we found a beneficial effect of 2 mo supplementation of infant formula with long-chain polyunsaturated fatty acids (LC-PUFA) on neurological condition at 3 mo in healthy term infants. The aim of the present follow-up study was to evaluate whether the effect on neurological condition persists until 18 mo. METHODS: A prospective, double-blind, randomized control study was conducted. Three groups were formed: a control (CF; n = 169), an LC-PUFA-supplemented (LF; n = 146) and a breastfed (BF; n = 159) group. Information on potential confounders was collected at enrolment. At the age of 18 mo, neurodevelopmental condition was assessed by the age-specific neurological examination of Hempel and the Bayley scales. The Hempel assessment resulted in a clinical neurological diagnosis, a total optimality score and a score on the fluency of motility. The Bayley scales resulted in mental and psychomotor developmental indices. Attrition at 18 mo was 5.5% and non-selective. Multivariate regression analyses were carried out to evaluate the effect of type of feeding while adjusting for confounders. RESULTS: None of the children had developed cerebral palsy and 23 (CF: n = 8; LF: n = 10; BF: n = 5) showed minor neurological dysfunction. The groups did not show statistically significant differences in clinical neurological condition, neurological optimality score, fluency score, and the psychomotor and mental development indices. Multivariate analysis confirmed that there was no effect of type of feeding on neurological condition. CONCLUSION: This study indicates that the beneficial neurodevelopmental effect of 2 mo LC-PUFA supplementation in healthy term infants can not be detected at the age of 18 mo.

Epidemiological studies indicate a positive relation between iron status and coronary artery disease (CAD) risk The HFE C282Y allele is associated with increased iron status and higher CAD risk. We investigated whether HFE C282Ymight be a CAD risk factor in Curaçao in a case-control study design. The patient group comprised 42 men and 10 women. Fifty-four men and 30 women without history of CAD served as age and gender matched controls. HFE C282Y genotypes were established using sequence-specific priming polymerase chain reaction. None of the investigated subjects were homozygous for HFE C282Y, whereas 5/52 (9.6%) CAD patients and 1/84 controls (1.2%) were heterozygous for HFE C282Y (p = 0.03). The HFE C282Y mutation was 8.8 fold (95% CI 1.001, 77.8; p = 0.049) more prevalent in CAD patients than in controls. The HFE C282Y allele frequency in Curaçao is higher than that of African populations, but comparable with that of Jamaica. We conclude that Curaçao CAD patients have somewhat higher frequency of HFE C282Y heterozygosity than controls, and that the HFE C282Y allele frequency in the Curaçao population is higher than might be expected in persons of African descent. The consequences of HFE C282Y heterozygosity as CAD risk factor are as yet uncertain, since there is no proof that iron lowering reduces CAD risk.

To investigate the minimal duration of exclusive breastfeeding for optimal neurological outcome, we assessed the quality of general movements (GM) at 3 mo of 147 breastfed healthy term infants that were followed from birth. The quality of GM is a sensitive marker of neurological condition. The quality of GM was classified as normal-optimal, normal-suboptimal, mildly abnormal and definitely abnormal. Information on social and pre- and perinatal conditions and the duration of breastfeeding was collected prospectively. Logistical regression analyses were used to adjust for confounders. There was a positive association between breastfeeding duration and movement quality, with a saturation effect at the age of approximately 6 wk. In the group of infants breastfed for < or = 6 wk (n = 55), 18% exhibited normal-optimal GM, 47% normal-suboptimal GM, and 47% mildly abnormal GM. In contrast, in the group of infants breastfed for > 6 wk (n = 92), 43% exhibited normal-optimal GM, 45% normal-suboptimal GM, and 12% mildly abnormal GM. Exclusive breastfeeding for >6 wk was therefore associated with markedly less abnormal and more normal-optimal GM. Thus, we conclude that breastfeeding for > 6 wk might improve the neurological condition in infants.

BACKGROUND: Homocysteine is a cardiovascular disease risk factor. We investigated, both in subjects with past plasma total homocysteine (tHcy) test indications and healthy adults, the diagnostic value of a fasting (tHcy) (f-tHcy) and the added value of a post-methionine-load tHcy (postload-tHcy). METHODS: Plasma homocysteine cut-off values were retrospectively used for hyperhomocysteinemia assessment in 3477 subjects with past tHcy test indications and 177 apparently healthy subjects. Cut-off values were based on reference limits (f-tHcy < or = 15.0; postload-tHcy < or = 50.0 micro mol/l), relative risk (f-tHcy < or = 12.0, postload-tHcy < or = 38.0; or f-tHcy < or = 10.0 micro mol/l) and vitamin-optimized reference limits (f-tHcy < or = 9.3; postload-tHcy < or = 35.1 micro mol/l). RESULTS: Use of the American Heart Association 10 micro mol/l f-tHcy cut-off value gave hyperhomocysteinemia prevalences of 65% in subjects with past tHcy test indications and 50% in healthy subjects. The combination of the vitamin-optimized reference limits for f-tHcy and postload-tHcy gave a hyperhomocysteinemia prevalence of 79% in subjects with tHcy test indications, of which only 5% was on account of increased postload-tHcy. Corresponding values for healthy subjects were 68% and 3%, respectively. CONCLUSIONS: Employment of a 10 micro mol/l (American Heart Association) or 9.3 micro mol/l (vitamin-optimized reference) cut-off value leaves no indications for tHcy testing from an evidence-based point-of-view.

UNLABELLED: Homocysteine is an intermediate in the folate cycle and methionine metabolism. This study investigated whether formula-fed infants have different plasma total homocysteine to their breastfed counterparts, and during what period any difference developed. Plasma total homocysteine was determined in 53 formula-fed and 15 breastfed healthy low-birthweight babies (< or = 2500 g) around days 10, 20 and 40. Total homocysteine was also measured in human milk. Mean +/- SD plasma total homocysteine levels (micromol l(-1)) at days 10, 20 and 40 were 6.4 +/- 2.6, 6.7 +/- 2.4 and 9.1 +/- 2.4 (breastfed), and 7.5 +/- 3.2, 7.3 +/- 2.1 and 7.4 +/- 1.6 (formula-fed). Homocysteine of breastfed babies at day 40 was higher than that of breastfed babies at day 20 (p < 0.0001), and that of formula-fed counterparts at day 40 (p = 0.002). Homocysteine correlated negatively with formula (day 10) and breast milk (day 40) volume intakes. Median (range) homocysteine in 12 mature human milk samples was 0.30 (not detectable to 0.7) micromol l(-1). CONCLUSION: Increasing plasma total homocysteine in breastfed babies to higher levels compared with formula-fed babies may be caused by a gradually developing suboptimal B-vitamin status in lactating women.

We determined optimal folate, vitamin B12 and vitamin B6 dosages in 21 sickle cell disease (SCD) patients (11 HbSS, 10 HbSC; mean 7 years, range 7-16), using plasma homocysteine (Hcy) as functional marker. They received daily 400 g (0-3 weeks), 700 g (3-6) and 1000 g (6-70) folate; 1 (0-21), 3 (21-45 and 5 RDA (45-70) vitamin B12; and 1 RDA vitamin B6 (0-70). Blood was taken at baseline (P0) and after 3 (PI), 6 (P2), 9 (P3), 21 (P4), 33 (P5), 45 (P6), 57 (P7) and 70 (P8) weeks for measurement of erythrocyte (RBC), serum folate, plasma vitamin B12, whole blood vitamin B6 and plasma Hcy. Vitamin B6 increased from P0 to P1 and P1 to P2; vitamin B12 from P4 to P8; serum folate from P0 to P1 and P1 to P2; RBC folate from P0 to P1, P1 to P2 and P2 to P3. Hcy decreased from P1 to P2 and P4 to P6. Most pronounced Hcy decreases occurred from P0 to P1 (43 percent of patients), P1 to P2 (14 percent) and P4 to P5 (24 percent). Haematological indices did not change. Patients with HbSS had higher RBC folate at P1, P2 and P8. The entire group exhibited inverse relations between RBC folate and haemoglobin on P1, P2, P3, P6, P7 and P8. We conclude that RBC folate is less valuable for folate status assessment in SCD patients. The optimal daily supplement is 700 g folate (3.5-7 RDA vitamin B12 (4.2-6.0 g) and 1 RDA vitamin B6 (1.4-2.0 mg). This combination causes Hcy levels that do not decrease further upon higher dosages and may reduce by simple and relatively inexpensive means their inherently high risk of endothelial damage.(Au)

Trinidadian Indians and Africans have different coronary artery disease (CAD) incidences. We determined apolipoprotein-E (apo-E) genotypes, and umbilical plasma cholesterol, triglycerides, apo-A1, apo-B and lipoprotein(a) [Lp(a) in 294 consecutive newborns in Trinidad. We calculate the apo-B/apo-A1 ratio and an adapted "lipid tetrad index" (i.e cholesterol*triglycerides*Lp(a)/apo-A1). Apo-E genotype distributions of Trinidadian Africans (allele frequencies: apo-e2:e3:e4=10.4:66.4:23.2 percent) and Indians(e2:e3:e4=3.5:83.1:13.4 percent) were different. The apo-E genotype distribution of Trinidadian Africans resembles to a certain extent that of their counterpart in Curacao and Sudan, but not that of cuonterparts in Nigeria and the USA.(AU)

We investigated whether paediatric patients with sickle cell disease (9ñ4 years; 27 HbSS; 19 HbSC) have different folic acid status compared with age-, sex-and race-matched HbAA controls (n=20), and whether their folic acid status can be improved by folic acid supplementation. The patients were supplemented with vitamins B6 and B12 during one week and with folic acid during the next week. Circulating folic acid, homocysteine, vitamin B6 and vitamin B12 levels were measured at baseline (patients and controls), after 1 and 2 weeks (patients). The patients had similar folic acid, vitamin B6 and vitamin B12, but higher homocysteine levels, compared with HbAA controls (12.7ñ4.5 vs 10.9ñ3.5 mmol/l;p=0.04). Vitamin B6 and B12 supplementation did not change their homocysteine levels, but folic acid supplementation caused a 52 percent reduction (to 5.7ñ1.6). We conclude that patients with sickle cell disease have adequate vitamin B6 and B12 status, but suboptimal folic acid status. They may benefit from folic acid supplementation to reduce their high risk for endothelial damage.(AU)

Nutritional deficiencies would appear to be an important determinant of morbidity in homozygous sickle cell (SS) disease. This is evidenced by the growth and development deficits which are observed in children with SS disease. In a study of the nutritional status of Jamaican children with SS disease aged 3 to 6 years, serum samples from blood taken after an overnight fast in the SS children and children of the same age with normal haemoglobin (AA) were collected. Micro-nutrient analyses of these serum samples for vitamin A (retinol) and vitamins E (alpha and gamma tocopherol) and the carotenoids, beta-carotene and lycopene were carried out using high performance liquid chromatography (HPLC). The results suggest that in children with SS disease several of the micro-nutrients which are essential for maintaining optimal antioxidant status are found in decreased amounts in serum. The confirmation of these micronutrients deficiencies in SS children provide the basis fo further exploration of their interrelationshipo with the growth and development deficits in this population.

Patients with coronary artery diseases are advised to augment their dietary linoleic acid intakes at the expense of saturated fatty acids. We investigated whether the dietary linoleic acid intake of 57 patients with coronary artery disease (47 males, 10 females; ages 61 ñ 10 years) in Curacao is higher as compared with 77 controls (51 males, 26 females; ages 56 ñ 7 years). For this, we measured plasma cholesterol ester fatty acids, which reflect the dietary fatty acid composition of the preceeding weeks. Patients with coronary artery disease and controls had minor differences in cholesterol ester fatty acids. Their cholesterol ester linoleic acid content suggests that the dietary polyunsaturated/saturated fatty acid ratio is far below 1. Comparison with data reported for the the Netherlands, Greenland and Crete showed that the dietary fatty acid composition in Curacao is typically Western with a high intake of saturated fatty acids, a low intake of monounsaturated fatty acids and the consumption of linoleic acid as the predominant polyunsaturated fatty acid. Intake of long chain polyunsaturated fatty acids from fatty fish is low. Reduction of dietary saturated fatty acids, augmentation of fish consumption, and an increase of the O-linolenic/linoleic acid ratio are likely to be of benefit to both primary and secondary prevention from coronary artery disease in Curaco.(AU)

We studied lipids, apolipoprotein-E (apo-E) genotypes and other coronary artery disease (CAD) risk factors of 67 CAD patients (male/female ratio 5) in Curacao. Compared with 57 controls, male CAD patients had higher cholesterol, triglycerides, LDL-cholesterol, apo-B and decreased HDL-cholesterol and HDL-cholesterol/cholesterol concentrations. Other CAD risk factors were: increased fasting glucose and Hba concentration, decreased creatinine clearance, and increased prevalences of lipoprotein (a) concentration > 500 mg/l, renal disease, hyperhomcysteinaemia, diabetes mellitus type II (DM-II), positive CAD family history and cigarette smoking. Male CAD patients had higher plasma O-tocopherol. Compared with 29 female controls, female CAD patients had higher fasting plasma glucose with HbA concentrations, and prevalence of DM-II. Predicting factors for CAD development in the whole CAD group were: DM-II, cigarette smoking, apo-E/E and apo-E/E Apo-E was associated with lower HDL-and higher LDL-cholesterol concentrations. There is a need for local studies on improvement of diabetic control, reference values of lipoprotein (a) and homocysteine concentrations, on apolipoprotein (a) phenotypes, causes of hyperhomocysteinaemia, and dietary influences on CAD development in subject who carry the apo-E allele.(AU)
