Association of maternal blood and umbilical cord blood plasma fatty acid levels with the body size at birth of Japanese infants. Prostaglandins Leukot Essent Fatty Acids 2024; 202:102638. [PMID: 39216412 DOI: 10.1016/j.plefa.2024.102638] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2024] [Revised: 08/14/2024] [Accepted: 08/19/2024] [Indexed: 09/04/2024]
Abstract
Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), mainly obtained from fish, have been implicated in fetal development. Because few studies have examined maternal and umbilical cord blood fatty acid levels and infant body size in Japan with a fish-eating culture, we examined differences in plasma fatty acid levels in pregnant women and infant size at birth. This study is a large birth cohort study of 1476 pairs of Japanese pregnant women and their infants. Maternal blood DHA levels and infant birth weight showed a positive relationship. However, analysis adjusted for gestational age did not reveal correlations. Negative relationships were found between cord blood DHA levels and infant body size, and between the difference in mother-to-child DHA levels and infant body size. Thus, the smaller the birth size, the higher the differences in umbilical cord blood DHA levels and mother-to-child DHA levels when considering gestational age.

Maternal Blood Fatty Acid Levels in Small and Adequate for Gestational Age Pregnancies. J Obstet Gynaecol India 2022; 72:217-223. [PMID: 35928082 PMCID: PMC9343542 DOI: 10.1007/s13224-022-01632-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2021] [Accepted: 02/01/2022] [Indexed: 10/18/2022] Open
Abstract
Background The aim is to assess the levels of fatty acids (FAs) in pregnancies with small for gestational age (SGA) and adequate for gestational age (AGA) fetuses, constituting an association between FAs and fetal growth; according to the role of FA, lower levels were expected in SGA. Materials and Methods This was an analytical cross-sectional study including pregnant women with gestational ages of 26-36 weeks with AGA and constitutionally SGA fetuses diagnosed by ultrasonography. The levels of saturated, trans, monounsaturated, and polyunsaturated fatty acids were measured using centrifugation and liquid chromatography. Student's t test and general linear model using gestational age as covariant were used to compare the levels of FAs and the groups (AGA and SGA). Chi-square was used to evaluate the association between groups and studied variables. Pearson correlation coefficient and linear regression were used to evaluate the correlation between the levels of FAs and gestational age. Results Peripheral blood was collected from 67 pregnant women, 3 of whom were excluded from the study. No significant statistical differences were observed between SGA (n = 40) and AGA (n = 24) in relation to saturated, trans, monounsaturated, and polyunsaturated fatty acids (p > 0.05). There was not significant correlation between saturated, trans, monounsaturated, and polyunsaturated FAs and gestational age (p > 0.05). Conclusion The levels of saturated, trans, monounsaturated, and polyunsaturated FAs were similar in constitutionally SGA and AGA fetuses.

Abstract
In evaluating vitamin E (VE) nutritional status of preterm infants, it is essential that any data should be compared with those of healthy term infants, and never with those of adults. Moreover, it should be evaluated in terms of gestational age (GA), not birth weight (BW), because placental transfer of most nutrients from mother to fetus is dependent on GA, not BW. Judging from the limited data during the last 75 years, there was no significant correlation between GA and VE concentrations in circulation or in the red blood cells (RBCs), leukocytes, and buccal mucosal cells. In addition, the oxidizability of polyunsaturated fatty acids (PUFAs) in plasma or RBCs, as targets for protection by VE chain-breaking ability, was lower in preterm infants. However, because of the minimal information available about hepatic VE levels, which is considered a key determinant of whole body VE status, the decision on whether VE status of preterm infants is comparable with that of term infants should be postponed. Clinical trials of VE supplementation in preterm infants were repeatedly undertaken to investigate whether VE reduces severity or inhibits development of several diseases specific to preterm infants, namely retinopathy of prematurity (ROP), bronchopulmonary dysplasia (BPD), and germinal matrix hemorrhage - intraventricular hemorrhage (GMH-IVH). Most of these trials resulted in a misfire, with a few exceptions for IVH prevention. However, almost all these studies were performed from 1980s to early 1990s, in the pre-surfactant era, and the study populations were composed of mid-preterm infants with GAs of approximately 30 weeks (wks). There is considerable difference in 'preterm infants' between the pre- and post-surfactant eras; modern neonatal medicine mainly treats preterm infants of 28 wks GA or less. Therefore, these results are difficult to apply in modern neonatal care. Before considering new trials of VE supplementation, we should fully understand modern neonatal medicine, especially the recent method of oxygen supplementation. Additionally, a deeper understanding of recent progress in pathophysiology and therapies for possible target diseases is necessary to decide whether VE administration is still worth re-challenging in modern neonatal intensive care units (NICUs). In this review, we present recent concepts and therapeutic trends in ROP, BPD, and GMH-IVH for those unfamiliar with neonatal medicine. Numerous studies have reported the possible involvement of reactive oxygen species (ROS)-induced damage in relation to supplemental oxygen use, inflammation, and immature antioxidant defense in the development of both BPD and ROP. Various antioxidants effectively prevented the exacerbation of BPD and ROP in animal models. In the future, VE should be re-attempted as a complementary factor in combination with various therapies for BPD, ROP, and GMH-IVH. Because VE is a natural and safe supplement, we are certain that it will attract attention again in preterm medicine.

Randomized controlled trial of early arachidonic acid and docosahexaenoic acid enteral supplementation in very preterm infants. Front Pediatr 2022; 10:947221. [PMID: 36090567 PMCID: PMC9452757 DOI: 10.3389/fped.2022.947221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Accepted: 07/25/2022] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVE To evaluate changes in blood long-chain polyunsaturated fatty acid (LCPUFA) and oxylipin concentrations in very preterm infants from birth to 36 weeks' postmenstrual age (WPA) after providing an emulsified arachidonic acid (ARA):docosahexaenoic acid (DHA) supplement at two different concentrations. STUDY DESIGN This prospective, randomized trial assigned infants to receive a supplement (1) 80:40 group (80 mg/kg/day ARA and 40 mg/kg/day DHA, n = 9) or (2) 120:60 group (120 mg/kg/day ARA and 60 mg/kg/day DHA, n = 9). Infants received supplement daily from birth until 36 WPA. At baseline, 21 days of life and 36 WPA, the LCPUFAs were measured in plasma by gas chromatography/mass spectrophotometry. Additionally, LCPUFAs and oxylipins were analyzed in whole blood by ultra-high-performance liquid chromatography-tandem mass spectrometry. Furthermore, a sample of oral mucosa was obtained to analyze single-nucleotide polymorphism located in the FADS1 gene by PCR. RESULTS Gestational age was similar between groups (80:40 = 28+6 [27+3; 30+3] completed weeks+days ; 120:60 = 29+6 [27+3; 30+5] completed weeks+days , p = 0.83). At 36 WPA, the change in plasma ARA was significantly different between groups (80:40 group = 0.15 [-0.67; 0.69] %nmol, 120:60 = 1.68 [1.38; 3.16] %nmol, p = 0.031). In whole blood, the levels of ARA-derived oxylipins (5-, 8-, 9-, 11-, 15-HETE and 8,9-EET) and EPA-derived oxylipins (18-HEPE) significantly increase from baseline to 36 WPA in the 120:60 group than the 80:40 group. CONCLUSION Supplementation at high doses (120:60 mg/kg/day) increased levels of ARA, and EPA- and ARA-derived oxylipins compared to low doses (80:40 mg/kg/day). Differences were detected in EPA metabolites without a significant increase in plasma DHA.

Abstract
Infant formula should provide the appropriate nutrients and adequate energy to facilitate healthy infant growth and development. If conclusive data on quantitative nutrient requirements are not available, the composition of human milk (HM) can provide some initial guidance on the infant formula composition. This paper provides a narrative review of the current knowledge, unresolved questions, and future research needs in the area of HM fatty acid (FA) composition, with a particular focus on exploring appropriate intake levels of the essential FA linoleic acid (LA) in infant formula. The paper highlights a clear gap in clinical evidence as to the impact of LA levels in HM or formula on infant outcomes, such as growth, development, and long-term health. The available preclinical information suggests potential disadvantages of high LA intake in the early postnatal period. We recommend performing well-designed clinical intervention trials to create clarity on optimal levels of LA to achieve positive impacts on both short-term growth and development and long-term functional health outcomes.

Abstract
Background:
Childhood malnutrition is a common public health problem in Ethiopia.
This animal study aims to evaluate the haematological, biochemical, and nutritional indices of
weanling albino rats fed on complementary diets developed from selected cereals and legumes.
Methods:
The nutritional qualities of the formulated blends were assessed biologically by feeding
white albino rats in order to determine feed intake, the growth rate, protein quality parameters, biochemical
and haematological properties. The commercial weaning diet (cerifam) and casein were
used as control diets. On the 28th day, blood samples were collected from three randomly selected
rats by decapitation. Full blood count analysis was carried out using the Automated Haematologic
Analyzer to determine haematological parameters. All the biochemical parameters were determined
using Mindray diagnostic kits.
Results and Discussion:
The food intake pattern showed that animals placed on diet 3, diet 4, casein,
and cerifam consumed more food than those fed on diet 1, diet 2, and diet 7. The mean
growth rate of animals fed on diet 3 and diet 4 was significantly (p<0.05) higher than those placed
on diet 1, diet 2, and diet 7 but similar to those fed with commercial diet and casein. The protein
quality evaluation of the diets showed that the protein efficiency ratio ranged from 1.20 to 2.43
while the biological value was in the range of 54.53 to 69.48%. The net protein utilization and true
digestibility were 65.62 to 70.21% and 59.01 to 64.01%, respectively. Serum total protein, albumin,
and globulin levels in rats given diet 3 and diet 4 were comparable to the controls and within
the normal range. Comparatively, the creatinine and urea levels of rats fed on the control and formulated
diets were within the normal range. The serum alanine aminotransferase values of rats fed
on the control and formulated diets ranged from 22.03 IU/L in diet 2 to 37.76 IU/L in diet 4 and
were not significantly different from each other. In this study, the packed cell volume and haemoglobin
values of the control and formulated diets were within the recommended range. Evidently,
diet 3 and diet 4 gave the best growth performance after the feeding trials.
Conclusion:
The haematological and biochemical indices indicate that these diets can support effective
growth and development in rats, and consumption of these diets has no detrimental effects
on the liver and renal function.

Abstract
The placenta represents a critical node in fetal lipid acquisition, yet the mechanisms by which the placenta handles lipids under normal and pathologic conditions are incompletely understood. A key player in placental lipid handling is peroxisome proliferator-activated receptor gamma (PPARγ). PPARγ influences global gene expression via its regulation of the epigenetic modifier lysine methyltransferase 5A (KMT5A), which places a methyl group on histone 4 lysine 20 (H4K20me) of target genes. Here we test the hypothesis that KMT5A is present in both the human and rat placentas and is affected by uteroplacental insufficiency (UPI) in the rat in association with increased placental lipid accumulation. We assessed levels and localization of KMT5A, as well as lipid droplet accumulation, in human placental tissue collected from maternal donors after delivery by planned cesarean section. Using a rat model of UPI, we also evaluated the effects of UPI on lipid accumulation, PPARγ, KMT5A, and H4K20me in the rat placenta. In this study, we show for the first time the presence and activity of KMT5A, in human and in rat placentas. We also demonstrate that in the rat placenta, UPI increases hypoxia, KMT5a expression, and activity in association with increased lipid accumulation in placenta supporting male fetuses. Placental PPARγ-KMT5A axis may be an important mediator of placental lipid handling.

Abstract
Long-chain polyunsaturated fatty acids (LCPUFAs) required for infant development are produced by Δ6 desaturase (D6D) and Δ5 desaturase (D5D). The D6D index and D5D index are calculated based on their respective precursor/product ratios. The D5D and D6D indices are related to obesity and lifestyle-related diseases. The aim of the present study was to examine the associations of umbilical cord fatty acid profiles, D6D index, and D5D index in appropriate for gestational age (AGA), small for gestational age (SGA), and large for gestational age (LGA) infants. This was a nested case-control study, and the relationship between case and control maternal blood and umbilical cord blood fatty acid compositions was examined. Cases were small for gestational age (SGA; n = 55) and large for gestational age (LGA; n = 149) infants, whereas controls were appropriate for gestational age (AGA; n = 204) infants. Fatty acid profiles in maternal blood and umbilical cord plasma were analyzed by gas-liquid chromatography. The D6D index was calculated as dihomo-γ-linolenic acid (DGLA 20: 3 n-6) / linoleic acid (18: 2 n - 6), and the D5D index was calculated as arachidonic acid (20: 4 n - 6) / DGLA (20: 3 n - 6). Statistical analysis of umbilical cord blood fatty acids was performed with multiple comparisons. SGA infants showed high umbilical cord values for α-linolenic acid and DHA and lower values for DGLA compared to AGA infants. SGA infants showed a higher D5D index but a lower D6D index than AGA infants. LGA infants showed high values for α-linolenic acid and DGLA and lower values for arachidonic acid than AGA infants. LGA infants showed a high D6D index and a low D5D index relative to AGA infants. No significant differences in maternal blood fatty acid profiles, the D6D index, and D5D index desaturase activities were found among the three groups. There were differences in umbilical cord fatty acid profiles and D6D and D5D indices among AGA, SGA, and LGA infants, but further study is needed.

Abstract
BACKGROUND Inflammation during pregnancy is hypothesized to influence fetal growth. Eicosanoids, an important class of lipid mediators derived from polyunsaturated fatty acids, can act as both direct influences and biomarkers of inflammation through a variety of biological pathways. However, quantifying these distinct inflammatory pathways has proven difficult. We aimed to characterize a comprehensive panel of plasma eicosanoids longitudinally across gestation in pregnant women and to determine whether levels differed by infant size at delivery. METHODS AND FINDINGS Our data come from a case-control study of 90 pregnant women nested within the LIFECODES prospective birth cohort study conducted at Brigham and Women's Hospital in Boston, Massachusetts. This study included 31 women who delivered small for gestational age (SGA) babies (SGA, ≤10th percentile), 28 who delivered large for gestational age (LGA) babies (≥90th percentile), and 31 who delivered appropriate for gestational age (AGA) babies (controls, >10th to <90th percentile). All deliveries occurred between 2010 and 2017. Most participants were in their early 30s (median age: 33 years), of white (60%) or black (20%) race/ethnicity, and of normal pre-pregnancy BMI (median BMI: 23.5 kg/m2). Women provided non-fasting plasma samples during 3 prenatal study visits (at median 11, 25, and 35 weeks gestation) and were analyzed for a panel of eicosanoids. Eicosanoids were grouped by biosynthetic pathway, defined by (1) the fatty acid precursor, including linoleic acid (LA), arachidonic acid (AA), docosahexaenoic acid (DHA), or eicosapentaenoic acid (EPA), and (2) the enzyme group, including cyclooxygenase (COX), lipoxygenase (LOX), or cytochrome P450 (CYP). Additionally, the concentrations of the 4 fatty acids (LA, AA, DHA, and EPA) were measured in maternal plasma. Analytes represent lipids from non-esterified plasma. We examined correlations among eicosanoids and trajectories across pregnancy. Differences in longitudinal concentrations between case groups were examined using Bayesian linear mixed effects models, which included participant-specific random intercepts and penalized splines on gestational age. Results showed maternal plasma levels of eicosanoids and fatty acids generally followed U-shaped curve patterns across gestation. Bayesian models showed that associations between eicosanoids and case status varied by biosynthetic pathway. Eicosanoids derived from AA via the CYP and LOX biosynthetic pathways were positively associated with SGA. The adjusted mean concentration of 12-HETE, a LOX pathway product, was 56.2% higher (95% credible interval 6.6%, 119.1%) among SGA cases compared to AGA controls. Eicosanoid associations with LGA were mostly null, but negative associations were observed with eicosanoids derived from AA by LOX enzymes. The fatty acid precursors had estimated mean concentrations 41%-97% higher among SGA cases and 33%-39% lower among LGA cases compared to controls. Primary limitations of the study included the inability to explore the potential periods of susceptibility of eicosanoids on infant size due to limited sample size, along with the use of infant size at delivery instead of longitudinal ultrasound measures to estimate fetal growth. CONCLUSIONS In this nested case-control study, we found that eicosanoids and fatty acids systematically change in maternal plasma over pregnancy. Eicosanoids from specific inflammation-related pathways were higher in mothers of SGA cases and mostly similar in mothers of LGA cases compared to controls. These findings can provide deeper insight into etiologic mechanisms of abnormal fetal growth outcomes.

Abstract
Docosahexaenoic acid (DHA, C22:6, ω-3), an ω-3 polyunsaturated fatty acid (PUFA), is critical for brain growth, development, and cognitive ability. It is consumed by offspring via milk during lactation. However, the toxic heavy metal lead (Pb) readily passes into the mammary glands of mother animals and then to offspring through milk. Here, we investigated whether DHA composition of milk and mammary gland tissues is affected by Pb exposure. Mother rats were exposed to Pb via drinking water (0.1%). The fatty acid profile and levels of reduced glutathione (GSH), lipid peroxide (LPO), and pro-inflammatory TNF-α in milk and mammary tissues were measured. Levels of DHA and antioxidant GSH decreased (P < 0.05), while LPO and TNF-α levels increased (P < 0.05) both in milk and mammary tissues. Our results suggest that toxic Pb exposure can upset the level of milk DHA, which may affect brain growth and development, and hence cognitive ability in adulthood and later life.

Abstract
Necrotizing enterocolitis (NEC) is a devastating gastrointestinal disease of incompletely understood pathophysiology predominantly affecting premature infants. While NEC is associated with microbial invasion of intestinal tissues, and mucus modulates interactions between microbes and underlying tissues, variations in mucus barrier properties with NEC-associated risk factors have not been investigated. This study explored differences in mucus composition (total protein, DNA, mucin content, sialic acid, and immunoregulatory proteins), as well as structural and transport properties, assessed by tracking of particles and bacteria (E. coli and E. cloacae) with developmental age and exposure to NEC stressors in Sprague Dawley rats. Early developmental age (5 day old) was characterized by a more permeable mucus layer relative to 21 day old pups, suggesting immaturity may contribute to exposure of the epithelium to microbes. Exposure to NEC stressors was associated with reduced mucus permeability, which may aid in survival. Feeding with breastmilk as opposed to formula reduces incidence of NEC. Thus, NEC-stressed (N-S) rat pups were orally dosed with breastmilk components lysozyme (N-S-LYS) or docosahexaenoic acid (N-S-DHA). N-S-LYS and N-S-DHA pups had a less permeable mucus barrier relative to N-S pups, which suggests the potential of these factors to strengthen the mucus barrier and thus protect against disease.

Abstract
This study was aimed to evaluate nutritional and antinutritional contents of complementary foods from locally available and affordable raw materials (maize, pea, and anchote) grown in Western Ethiopia. The six formulated complementary diets analyzed for their proximate, mineral, and antinutritional continents were compared with Codex standards. The mineral ratios and molar ratios of the formulated diets were also evaluated and compared with each standard values. Six formulations were generated by d-optimal mixture design. The formulated ingredient ranges 45%-61% maize, 23%-31% pea, and 14%-28% anchote. Design-Expert® 6 (Stat-Ease) was used to constrain the three components. The formulated diets ranged from 14.92% to 20.99%, 5.95% to 9.94%, 2.75% to 3.41%, and 59.10% to 66.22% of protein, fat, fiber, and utilizable carbohydrate, respectively. Mineral contents (mg/100 g) of the formulated diet ranged from 225.45 to 261.32, 11.48 to 12.61, 2.73 to 3.00, 357.92 to 391.13, 298.55 to 332.63, 252.00 to 278.01, and 44.26 to 51.56 for calcium, iron, zinc, phosphorous, potassium, sodium and magnesium, respectively. The proximate and mineral contents of the formulated diet 5 meet the Codex standards, except the fat contents of the complementary food standards. The molar ratios of the formulated diets in this study were below standard reference and which show the high mineral bioavailability in all the formulated diets. The results of the study revealed that the formulated diets contain very low antinutritional factors and high mineral bioavailability. The paper's findings show that the complementary food formulated from maize, pea, and anchote flours particularly diet 5 may be suitable to alleviate protein energy malnutrition and it can be used as a substitute for the expensive commercial complementary food.

Abstract
The study aimed to test whether or not milk fatty acid composition in mothers of small for gestational age (SGA) infants is similar to that in mothers of adequate for gestational age (AGA) infants. Thirty three mothers of SGA preterm infants and 66 mothers of AGA preterm infants were included. Milk and plasma fatty acids were analyzed using capillary gas chromatography. Milk DHA (0.68 ± 0.37 vs. 0.44 ± 0.24; p < 0.01) was higher and n-6:n-3 PUFA ratio (12.0 ± 4.64 vs. 16.0 ± 6.32; p < 0.05) was lower in mothers of SGA infants. Plasma ARA and DHA were increased in mothers of SGA infants and decreased in their infants. Milk ARA or DHA was positively related to the correspondent fatty acid in plasma (r = 0.374, p = 0.010 for ARA and r = 0.690, p < 0.001 for DHA). Breast milk in mothers of preterm infants born SGA is enriched in DHA and n-3 PUFA. Breastfeeding SGA preterm infant with own mother's milk is recommended.

Abstract
Arachidonic (AA) and docosahexaenoic (DHA) acids are essential for the health and development of the neonate. Red blood cell (RBC) fatty acids were analyzed in 583 very low birth weight (VLBW) infants and 274 term infants using capillary gas chromatography. VLBW infants exhibited significantly lower RBC AA (13.0 ± 0.89 vs. 13.5 ± 0.98) and DHA (3.77 ± 0.60 vs. 3.80 ± 0.62), but higher n6:n3 ratio (3.97 ± 0.46 vs. 3.63 ± 0.37) than term infants. In VLBW infants, DHA was lower in those born with small for gestational age (3.69 ± 0.57 vs. 3.86 ± 0.58) and those who suffered from neonatal sepsis (3.73 ± 0.60 vs. 3.86 ± 0.55). Both AA and DHA were significantly lower in infants who developed respiratory distress syndrome or intraventricular hemorrhage, and those who died during the hospital stay. VLBW infants had lower postnatal RBC AA and DHA levels than term infants did. These deficits are associated with higher risk of neonatal morbidities and mortality.

Abstract
Neovascular eye diseases, including retinopathy of prematurity, diabetic retinopathy, and age-related macular degeneration, threaten the visual health of children and adults. Current treatment options, including anti-vascular endothelial growth factor therapy and laser retinal photocoagulation, have limitations and are associated with adverse effects; therefore, the identification of additional therapies is highly desirable. Both clinical and experimental studies show that dietary ω-3 (n-3) long-chain polyunsaturated fatty acids (LC-PUFAs) reduce retinal and choroidal angiogenesis. The ω-3 LC-PUFA metabolites from 2 groups of enzymes, cyclooxygenases and lipoxygenases, inhibit [and the ω-6 (n-6) LC-PUFA metabolites promote] inflammation and angiogenesis. However, both of the ω-3 and the ω-6 lipid products of cytochrome P450 oxidase 2C promote neovascularization in both the retina and choroid, which suggests that inhibition of this pathway might be beneficial. This review summarizes our current understanding of the roles of ω-3 and ω-6 LC-PUFAs and their enzymatic metabolites in neovascular eye diseases.

Abstract
The aim of this study was to evaluate the effect of blending ratio of malted barley, maize, and roasted pea flour on complementary food quality and sensory acceptability. D- Optimal mixture design was used to generate 14 formulations. Each ingredient had 55-90% maize, 20-35% pea and 4-12% malted barley. Pretreatments like debranning of maize, roasting of pea and dehusking of malted barley were done. The three component-constrained mixture design was conducted using Design-Expert® 6 (Stat-Ease). Ash, protein, fat, fiber, moisture, and carbohydrate contents were found in between range of 1.5-2.5%, 13.0-18.5%, 1.8-2.5%, 3.06-4.45%, 5.0-6.5%, and 68.9-74.1%, respectively. Significant difference (P < 0.05) among the treatments was observed for protein, moisture, odor, flavor and sensory overall acceptability. Lack-of-fit was significantly different only for fat (R2 = 0.90). Thus, the model generated can predict all attributes except for fat. The optimum values of high nutrient content and sensory acceptability were observed in the range of 55.0-68.5%, 27.5-35.0%, and 4.0-10.0% for maize, pea, and malted barley respectively.

Prostaglandins Leukot Essent Fatty Acids 2016; 109:22-8.

Abstract
INTRODUCTION During pregnancy and lactation, there is a high need of long-chain (LC) omega-3 fatty acids (n-3 PUFA), especially docosahexaenoic acid (DHA), for fetus and infant. Also, a low LC n-3 PUFA status during pregnancy is associated with postpartum depression. The aim of this cross-sectional study was to analyze the LC n-3 PUFA status in German women during pregnancy and lactation. MATERIAL AND METHODS As a part of a nationwide cross-sectional study in which the nutrient status of women in different stages of life was determined, 213 pregnant (≥27th week of gestation) and 127 lactating women between 18 and 44 years were evaluated regarding their LC n-3 PUFA status by measuring the omega-3 index (relative eicosapentaenoic acid (EPA) and DHA concentration in erythrocyte fatty acid). RESULTS The mean omega-3 index of the total study population was 6.23±1.48%. Pregnant women showed significant (p≤0.001) higher omega-3 index values (6.40±1.31%) and DHA concentrations (5.91±1.23%) than lactating women (omega-3 index: 5.50±1.34%; DHA: 4.79±1.27%). Woman with LC n-3 PUFA supplementation showed higher omega-3 index values (7.73±1.28%) vs. women without supplementation (6.04±1.39%, p≤0.001). Week of pregnancy, month of lactation as well as smoking were negatively associated with the omega-3 index. CONCLUSION Comprehensive data on the long-term LC n-3 PUFA status of German women during pregnancy and lactation are presented. To evaluate an optimal maternal omega-3 index in view of the fetal and infant development further studies are needed.

Abstract
Maternal nutrition plays a crucial role in influencing fertility, fetal development, birth outcomes, and breast milk composition. During the critical window of time from conception through the initiation of complementary feeding, the nutrition of the mother is the nutrition of the offspring—and a mother’s dietary choices can affect both the early health status and lifelong disease risk of the offspring. Most health expert recommendations and government-sponsored dietary guidelines agree that a healthy diet for children and adults (including those who are pregnant and/or lactating) should include an abundance of nutrient-rich foods such as fruits and vegetables. These foods should contain a variety of essential nutrients as well as other compounds that are associated with lower disease risk such as fiber and bioactives. However, the number and amounts of nutrients varies considerably among fruits and vegetables, and not all fruit and vegetable options are considered “nutrient-rich”. Avocados are unique among fruits and vegetables in that, by weight, they contain much higher amounts of the key nutrients folate and potassium, which are normally under-consumed in maternal diets. Avocados also contain higher amounts of several non-essential compounds, such as fiber, monounsaturated fats, and lipid-soluble antioxidants, which have all been linked to improvements in maternal health, birth outcomes and/or breast milk quality. The objective of this report is to review the evidence that avocados may be a unique nutrition source for pregnant and lactating women and, thus, should be considered for inclusion in future dietary recommendations for expecting and new mothers.

Abstract
BACKGROUND Preterm birth has a dramatic impact on polyunsaturated fatty acid exposures for the developing brain. This study examined the association between postnatal fatty acid levels and measures of brain injury and development, as well as outcomes. METHODS A cohort of 60 preterm newborns (24-32 wk gestational age) was assessed using early and near-term magnetic resonance imaging (MRI) studies. Red blood cell fatty acid composition was analyzed coordinated with each scan. Outcome at a mean of 33 mo corrected age was assessed using the Bayley Scales of Infant Development, 3rd edition. RESULTS Adjusting for confounders, a 1% increase in postnatal docosahexaenoic acid (DHA) levels at early MRI was associated with 4.3-fold decreased odds of intraventricular hemorrhage, but was not associated with white matter injury or cerebellar haemorrhage. Higher DHA and lower linoleic acid (LA) levels at early MRI were associated with lower diffusivity in white matter tracts and corresponding improved developmental scores in follow-up. CONCLUSION Higher DHA and lower LA levels in the first few weeks of life are associated with decreased intraventricular haemorrhage, improved microstructural brain development, and improved outcomes in preterm born children. Early and possibly antenatal interventions in high-risk pregnancies need to be studied for potential benefits in preterm developmental outcomes.

Abstract
Long chain polyunsaturated fatty acids (LCPUFA) including docosahexaenoic acid (DHA) and arachidonic acid (ARA) are increasingly transferred from mother to fetus late in pregnancy. Infants born before this transfer is complete are at risk for deficiency. This study determines the relationship between gestational age (GA) and circulating LCPUFA levels to better understand the unique needs of premature infants born at various GAs. Whole blood was collected within the first 7 days of life from 60 preterm (≤34 weeks GA) and 30 term infants (≥38 weeks GA) and FA levels were analyzed. Since concurrent intravenous lipid emulsion can skew composition data, blood LCPUFA concentrations were also measured. Levels were compared among groups, and linear regression models were used to examine the association between FA composition and GA. Preterm infants had significantly lower DHA and ARA levels than term peers, and whether assessed as concentrations or compositions, both directly correlated with GA (p<0.0001). Moreover, FA comparisons suggest that premature infants have impaired synthesis of LCPUFAs from precursors and may require preformed DHA and ARA. This study confirms that essential FA status is strongly related to GA, and that those babies born the earliest are at the greatest risk of LCPUFA deficiency.

Abstract
Long-chain polyunsaturated fatty acids (LCPUFA) including docosahexaenoic acid (DHA) are essential for normal vision and neurodevelopment. DHA accretion in utero occurs primarily in the last trimester of pregnancy to support rapid growth and brain development. Premature infants, born before this process is complete, are relatively deficient in this essential fatty acid. Very low birth weight (VLBW) infants remain deficient for a long period of time due to ineffective conversion from precursor fatty acids, lower fat stores and a limited nutritional provision of DHA after birth. In addition to long-term visual and neurodevelopmental risks, VLBW infants have significant morbidity and mortality from diseases specific to premature birth, including bronchopulmonary dysplasia, necrotizing enterocolitis, and retinopathy of prematurity. There is increasing evidence that DHA has protective benefits against these disease states. The aim of this article is to identify the unique needs of premature infants, review the current recommendations for LCPUFA provision in infants and discuss the caveats and innovative new ways to overcome the DHA deficiency through postnatal supplementation, with the long-term goal of improving morbidity and mortality in this at-risk population.

Abstract
Conventional assays of omega-3 long chain polyunsaturated fatty acid (n-3 LCPUFA) status in humans involve venous blood collection and expensive, multi-step processes that limit their usefulness as screening tools. This study aimed to develop a capillary dried blood spot (DBS) system capable of protecting n-3 LCPUFA from oxidation for up to 2 months at room temperature (20-25°C). We demonstrated that a DBS system comprising both an antioxidant and chelating agent on silica-gel coated paper prevented any significant change in the n-3 LCPUFA profile after 2 months. Our DBS assay was then tested in fifty subjects, and this demonstrated the presence of strong and significant correlations between the results obtained from the DBS system and those obtained from conventional measures for all fatty acids, in particular the n-3 LCPUFA EPA and DHA (r>0.96, P<0.0001). This study therefore validates our DBS system as a reliable method for the assessment of n-3 LCPUFA status in humans.

Abstract
Long chain polyunsaturated fatty acids (LC-PUFA), especially the Omega 3, modulate key functions in the body. Their circulating levels are representative of their "status", and may vary at different ages. We have compared the FA status in Italian subjects from neonates to adulthood, assessed through FA analysis of blood drops from fingertips. Data from four cohorts of Italian subjects (total number 1835), have been pooled in four age-groups: neonates (4 days, n=81), children (2-9 years, n=728), adults (40-59 years, n=434) and elderly (60-79 years, n=592). LC-PUFA of both series (Omega 3 and 6) are higher in the blood of neonates than at subsequent ages, reflecting the efficient transfer of these FA from mothers to the fetus. In contrast, the lowest levels of Omega 3 PUFA, especially of DHA, are found in children, probably reflecting inadequate dietary intakes, with possible consequences on the health status at subsequent ages.

Abstract
OBJECTIVE To determine fatty acid levels in the US donor milk supply. STUDY DESIGN Donor human milk samples from Iowa (n=62), Texas (n=5), North Carolina (n=5) and California (n=5) were analyzed by gas chromatography. Levels in the Iowa donor milk were compared before and after pasteurization using Student's t-test. Docosahexaenoic acid (DHA) and arachidonic acid (ARA) levels were compared among all milk banks using analysis of variance. RESULT ARA (0.4 pre, 0.4 post, P=0.18) and DHA (0.073 pre, 0.073 post, P=0.84) were not affected by pasteurization. DHA varied between banks (P<0.0001), whereas ARA did not (P=0.3). DHA levels from all banks were lower than published values for maternal milk and infant formula (P<0.0001). CONCLUSION Pasteurization of breastmilk does not affect DHA or ARA levels. However, DHA content in US donor milk varies with bank location and may not meet the recommended provision for preterm infants.

Abstract
Over the last few decades n-3 long chain polyunsaturated fatty acid status became of special interest for scientists. Biochemical measures on the n-3 fatty acid status vary depending on body compartment assessed and measures chosen. Plasma phospholipids and red blood cell membrane phospholipids are mainly used as n-3 fatty acid status marker. The conventional analysis of phospholipid fatty acids involves lipid extraction and consecutive chromatographic separation of phospholipids from other lipid fractions, which is time-consuming and costly. In recent years, different investigators have tried to overcome these limitations by using other biological markers or by modifying the analytical procedures used to assess n-3 fatty acid status. The aim of this systematic review was to provide an overview on these novel analytical methods developed for the fatty acid quantification by gas chromatography, highlights the methodological limitations, and discusses advantages or disadvantages of the biological markers used. Seventeen papers were identified that fulfilled the inclusion criteria. New opportunities arise from sensitive and precise high-throughput methodologies for assessment of plasma total lipid and plasma glycerophospholipid fatty acids, as well as cheek cell fatty acid composition.

Abstract
BACKGROUND & AIMS The biological role of fatty acids (FA) in the perinatal period is under active investigation. We here describe the application of a simplified microanalytical procedure to compare the FA profile of maternal, umbilical cord and infant whole blood, inclusive of all circulating lipid fractions and cells. METHODS The FA composition has been analyzed with a micromethod in 16 triplets, including maternal blood, cord blood at delivery and infant blood at day 4, respectively. RESULTS As expected, the FA composition of blood samples withdrawn from the umbilical cord is more similar to the FA composition of blood from 4-day old infants than the FA pattern of maternal blood at delivery. Nevertheless, infant blood FA profile differed from cord for lower long-chain polyunsaturated FA and higher monounsaturated FA. CONCLUSIONS Our explorative data using whole blood microanalysis confirm the progressive increase of long-chain polyunsaturated FA levels from the mothers towards cord and then infant blood.

Abstract
The purpose of this study was to examine the maternal and cord long-chain polyunsaturated fatty acid (LCPUFA) concentrations and their associations with birth outcome in term deliveries. Pregnant women (n = 253) delivering at term were divided into two groups based on their babies' birth weights (1) normal birth weight (NBW), that is, ≥2.5 kg (n = 190) and (2) low-birth weight (LBW), that is, <2.5 kg (n = 63). Each group is further divided into two groups according to the baby's sex, that is, male NBW (M-NBW), female NBW (F-NBW), male LBW (M-LBW), and female LBW (F-LBW) groups. Maternal plasma docosahexaenoic acid and erythrocyte arachidonic acid (AA) levels were lower (P < 0.05 for both), while cord plasma docosahexaenoic acid and erythrocyte AA levels were higher (P < 0.05 for both) in LBW group when compared to the NBW group. Maternal erythrocyte AA levels were positively associated with birth weight (P = 0.001), while cord plasma docosahexaenoic acid levels were negatively (P = 0.05) associated with birth weight. Reduced maternal and increased cord LCPUFA levels exist in mothers delivering LBW babies, especially in mothers delivering female babies, indicative of sex-specific effects.
