During cardiac failure, cardiomyocytes have difficulty in using the substrates to produce energy. L-carnitine is a necessary nutrient for the transport of fatty acids that are required for generating energy. Coronary artery graft surgery reduces the plasma levels of L-carnitine and increases the oxidative stress. This study demonstrates the effect of L-carnitine supplementation on the reverse remodeling of patients undergoing coronary artery bypass graft. Patients with ischemic heart failure who underwent coronary graft surgery were randomized to group A - supplemented with L-carnitine or group B controls...

INTRODUCTION: In phenylketonuria (PKU), a natural protein-restricted dietary treatment prevents severe cognitive impairment. Nutrient deficiencies may occur due to strict diet. This study is aimed at evaluating the dietary intake and blood concentrations of micronutrients and essential fatty acids (FA), bone mineral density (BMD) and fracture history in patients on long-term dietary treatment. METHODS: Sixty early diagnosed Dutch patients (aged 1-39 years) were included in a multi-center cross-sectional study...

BACKGROUND: In the past, elevated estradiol levels were reported to downregulate the iron regulatory hormone hepcidin, thereby potentially improving iron metabolism. As estrogen plays a role in regulating the menstrual cycle and can influence the cytokine interleukin-6 (IL-6; a hepcidin up-regulator), this investigation examined the effects of estradiol supplementation achieved by the use of a monophasic oral contraceptive pill (OCP) on IL-6, hepcidin levels and iron status during the hormone-deplete versus hormone-replete phases within an oral contraceptive cycle (OCC)...

BACKGROUND: Iron is considered a nutrient of concern for vegetarians. In children, inadequate iron status may lead to anemia and poor growth. SUMMARY: Thirteen original manuscripts met the inclusion criteria. Various biochemical markers of iron status, such as hemoglobin (Hb) and serum ferritin, were used. Seven of the 13 studies reported the prevalence of iron deficiency separately for vegetarians and non-vegetarians. Five out of 7 showed a higher prevalence of iron deficiency among the vegetarian participants, while the other 2 showed a higher prevalence of iron deficiency among non-vegetarians...

BACKGROUND: Vitamin D deficiency is an unrecognized epidemic found in India and also worldwide. Despite the high prevalence of diabetes among Indians, there is a paucity of data showing the relationship between vitamin D status and cardiometabolic disparities. In this study, we have examined the relationship between vitamin D and cardiometabolic traits in a population from India. METHODS: Circulating 25(OH)D levels were measured in 3,879 participants from the Asian Indian Diabetic Heart Study using ELISA kits...

BACKGROUND: An increasing number of studies show low diversity of the gut microbiome in those with chronic diseases such as obesity, inflammatory bowel disease, and allergy. Manipulation of the microbiota may promote health. However, the adult microbiota is stable and may be difficult to change. Understanding the fixed and modifiable factors, which determine colonization in early life, may provide strategies for acquisition of a health-promoting microbiome. SUMMARY: Not enough is known about the long-term effects of established determinants of gut colonization, including delivery mode, perinatal antibiotics, and infant diet...

Infants are born equipped to ingest nutrients, but because of the transitions in the mode of feeding in the first years (from "tube" feeding in utero to eating table foods with the family), they have to learn how, what and how much to eat. Eating behavior established during early years may follow throughout childhood; therefore, it is fundamental to understand the most important drivers of the early development of eating behavior. Beyond the first flavor discoveries during the gestational and lactation periods (through the infant's exposure to flavors from foods of the mother's diet), the most important phases for learning food preferences and appetite control may be the beginning of complementary feeding (CF)...

BACKGROUND: The increasing incidence of childhood obesity is a significant public health challenge, the consequences of which extend across the life course. SUMMARY: Diet and exercise are clearly the major contributors to childhood obesity, but the factors predisposing to obesity may become established in the womb. Worryingly maternal overnutrition, in particular when it leads to obesity and diabetes, perpetuate an intergenerational cycle of obesity through its effects on placental function and fetal metabolism...

BACKGROUND: Whilst prevention of growth faltering has both short- and long-term health benefits, whether too fast or accelerated infant growth adversely affects later health outcomes is controversial and a major focus of research. SUMMARY: Many observational studies suggest that rapid weight gain in infancy (upward centile crossing) increases the long-term risk of obesity and non-communicable disease. This association has been seen in infants from low- and high-income countries, in infants born preterm or at term, and those born with normal or low birth weight for gestation...

BACKGROUND: Many very preterm (i.e., <32 weeks of gestation) newborns fail to mount an adequate adrenocortical response to stress or illness, termed relative adrenal insufficiency. Conversely, later in life these infants show features of increased glucocorticoid bioactivity, such as abdominal adiposity, insulin resistance, raised blood pressure, shorter stature and internalizing problem behavior. SUMMARY: Studies suggested that very preterm newborns have impairments along multiple levels of the hypothalamus-pituitary-adrenal (HPA) axis...

Stewart Forsyth, Sheila Gautier, Norman Salem
BACKGROUND: In developing countries, dietary intakes of arachidonic acid (ARA) and docosahexaenoic acid (DHA) in early life are lower than current recommended levels. This review specifically focusses on the contribution that complementary feeding makes to ARA and DHA intakes in medium- to low-income countries. The aims of the review are (1) to determine the availability of ARA and DHA food sources in developing countries, (2) to estimate the contribution of complementary feeding to dietary intakes of ARA and DHA in infants aged 6-36 months, and (3) to relate the dietary ARA and DHA intake data to key socioeconomic and health indicators...

BACKGROUND: A majority of adipose tissue present in the newborn possess the unique mitochondrial protein, uncoupling protein (UCP1). It is thus highly metabolically active and capable of producing 300 times more heat per unit mass than any other organ in the body. The extent to which maternal obesity and/or an obesogenic diet impacts on placental function thereby resetting the relative distribution of different types of fat in the fetus is unknown. SUMMARY: Developmentally the majority (if not all) fat in the fetus can be considered as classical brown fat, in which UCP1 is highly abundant...

BACKGROUND: Exposures during early life are increasingly being recognised as factors that play an important role in the aetiology of chronic non-communicable diseases (NCDs). The "Developmental Origins of Health and Disease" (DOHaD) hypothesis asserts that adverse early-life exposures - most notably unbalanced nutrition - leads to an increased risk for a range of NCDs and that disease risk is highest when there is a "mismatch" between the early- and later-life environments. Thus, the DOHaD hypothesis would predict highest risk in settings undergoing a rapid nutrition transition...

BACKGROUND: Childhood overweight and obesity are a non-deniable health concern with increasing economic attention. SUMMARY: International studies provide robust evidence about substantial lifetime excess costs due to childhood obesity, thereby underscoring the urgent need to implement potent obesity prevention programs in early childhood. Fortunately, this is happening more and more, as evidenced by the increase in well-conducted interventions. Nevertheless, an important piece of the puzzle is often missing, that is, health economic evaluations...

BACKGROUND: Over the last decades, research on early life risk factors for obesity and its comorbidities in early life has gained attention within the field of developmental origins of health and diseases. Metabolomics studies that are trying to find early life biomarker and intervention targets for the early development of obesity and associated cardiovascular diseases could help break the inter-generational cycle of obesity. SUMMARY: Metabolomics studies in the field of early programming are scarce and causality is lacking at this stage, as most of the studies are cross-sectional...

BACKGROUND: Several studies about humans and animals have separately examined the effects of prenatal nutrition and stress on fetal development, pregnancy, and birth outcomes, and subsequent child health and disease risk. Although substantial evidence from non-pregnant literature supports the presence of bidirectional interactions between nutrition and stress at various psychological, behavioral, and physiological levels, such interaction effects have not yet been systematically examined in the context of pregnancy...

BACKGROUND/AIMS: The aim of the present study was to identify and quantify the polyamine levels in human milk obtained from different countries and through different modes of delivery, and to investigate their association with breast milk microbes. METHODS: Mature breast milk samples were obtained from 78 healthy mothers after 1 month of lactation from 4 different geographical locations: Finland, Spain (Europe); South Africa (Africa); and China (Asia). Polyamines were determined using HPLC after dansyl derivatization and milk microbiota was obtained by 16S rRNA gene sequencing...

BACKGROUND/AIMS: Many environmental toxicants are passed to infants in utero and through breast milk. Exposure to toxicants during the perinatal period can alter growth patterns, impairing growth or increasing obesity risk. Previous studies have focused on only a few toxicants at a time, which may confound results. We investigated levels of 26 toxicants in breast milk and their associations with rapid infant growth, a risk factor for later obesity. METHODS: We used data from the Norwegian HUMIS study, a multi-center cohort of 2,606 mothers and newborns enrolled between 2002 and 2008...

BACKGROUND: Several studies have reported increased resting energy expenditure (REE) in human immunodeficiency virus (HIV)-infected patients with HIV-associated lipodystrophy syndrome (HALS). However, limited data exist on the total energy expenditure (TEE). This study was aimed at evaluating the REE and TEE of HIV-infected patients with and without HALS by using the doubly labeled water (DLW) technique and the activity monitor based on accelerometry system (AM), and comparing the results obtained using both methods...
