During gestation, fetal nutrition is entirely dependent on maternal diet. Maternal consumption of excess fat during pregnancy has been linked to an increased risk of neurologic disorders in offspring, including attention deficit/hyperactivity disorder, autism, and schizophrenia. In a mouse model, high-fat diet (HFD)-fed offspring have cognitive and executive function deficits as well as whole-genome DNA and promoter-specific hypomethylation in multiple brain regions. Dietary methyl donor supplementation during pregnancy or adulthood has been used to alter DNA methylation and behavior...

RATIONALE: Disseminated intravascular coagulation (DIC) induced by daily rifampicin therapy is rare, especially the patient is absent of malignancy, severe infection, and prior exposure to rifampicin. PATIENT CONCERNS: We report a case of DIC induced by daily rifampicin treatment for pulmonary tuberculosis. A 22-year-old, previously healthy man received an anti-tuberculosis therapy consisting of isoniazid, rifampicin, ethambutol, and pyrazinamide on the daily dose recommended by the World Health Organization tuberculosis guidelines after a diagnosis of pulmonary tuberculosis...

PURPOSE OF REVIEW: Maternal and child malnutrition continues to disproportionately affect low and middle-income countries, contributing to high rates of morbidity, mortality, and suboptimal development. This article reviews evidence from recent systematic reviews and studies on the effectiveness of interventions to improve nutritional status in these especially vulnerable populations. RECENT FINDINGS: Macronutrients provided to expectant mothers in the form of balanced protein energy supplements can improve fetal growth and birth outcomes, and new research suggests that lipid nutrient supplements can reduce both stunting and wasting in newborns...

Maternal diet and lifestyle choices may affect placental transfer of cobalamin (Cbl) to the fetus. Fetal liver concentration of Cbl reflects nutritional status with regards to vitamin B12, but at these low concentration current Cbl measurement methods lack robustness. An analytical method based on enzymatic extraction with subsequent reversed-phase-high-pressure liquid chromatography (RP-HPLC) separation and parallel ICPMS and electrospray ionization (ESI)-Orbitrap-MS to determine specifically Cbl species in liver samples of only 10-50 mg was developed using 14 pig livers...

Many of information on the safety of drugs during pregnancy were obtained many years ago, before the pregnant women were excluded from the study protocols for possible fetal risks. Because randomized trials in pregnancy are complex and considered unethical. For the same reasons, there are no randomized controlled trials in pregnant women on dialysis. Moreover Compared to the normal subject, the pharmacokinetics and pharmacodynamics in these patients are influenced or by pregnancy or from dialysis techniques or from chronic uremia...

Insufficient nutrition during the perinatal period causes structural alterations in humans and experimental animals, leading to increased vulnerability to diseases in later life. Japanese quail, Coturnix japonica, in which partial (8-10%) egg white was withdrawn (EwW) from eggs before incubation had lower birth weights than controls (CTs). EwW birds also had reduced hatching rates, smaller glomeruli and lower embryo weight. In EwW embryos, the surface condensate area containing mesenchymal cells was larger, suggesting that delayed but active nephrogenesis takes place...

Pregnancy after bariatric surgery has some peculiarities related to obesity, type of surgery, amount of weight loss, time elapsed from the surgery and adherence to medical prescriptions. Pregnant woman is at risk of nutritional deficiencies and it is unclear whether there is an increased incidence of intestinal complications during pregnancy after bariatric surgery and whether this kind of complications are more frequent during cesarean section. The fetus is at high risk of prematurity and fetal growth restriction, but they seem not at increased risk of birth defects (DTN) except in individual cases of folic acid deficiency (DTN) or vitamin K defect (similar abnormalities in patients receiving oral anticoagulants)...

REVIEW
Haerani Rasyid, Syakib Bakri
Low birth weight (LBW) is defined as a birth weight of a liveborn infant of <2,500 gram. In developed countries, LBW is commonly caused by preterm birth; while in developing countries, it is mostly due to intrauterine growth retardation. The concept of developmental origins of adult diseases, particularly on late-onset diseases such as hypertension and kidney disease, implies that there is a correlation between intrauterine milieu, intrauterine growth retardation, premature birth and infant feeding. The 'fetal origin hypothesis' suggests that metabolic diseases are directly related to poor nutritional status in early life...

BACKGROUND: Unhealthy nutrition and lifestyle contribute to the worldwide rising prevalence of non-communicable diseases. This also accounts for the reproductive population, in which unhealthy behavior affects fertility and pregnancy outcome. Maternal smoking, alcohol consumption and inadequate folic acid supplement use are strongly associated with fetal complications as small for gestational age, premature birth and congenital malformations. In the Netherlands 83% of the perinatal mortality rate is due to these complications and is relatively high compared to other European countries...

BACKGROUND: Perinatal mortality and morbidity continue to be major global health challenges strongly associated with prematurity and reduced fetal growth, an issue of further interest given the mounting evidence that fetal growth in general is linked to degrees of risk of common noncommunicable diseases in adulthood. Against this background, WHO made it a high priority to provide the present fetal growth charts for estimated fetal weight (EFW) and common ultrasound biometric measurements intended for worldwide use...

Disruption of steroid hormone signaling has been implicated independently in the developmental abnormalities resulting from maternal phthalate plasticizer exposure and developmental zinc deficiency. This study investigated if secondary zinc deficiency may result from dietary exposure to a low level of DEHP through gestation and if this could be associated with altered steroid metabolism. The interaction between marginal zinc nutrition and DEHP exposure to affect pregnancy outcome, zinc status, and steroid metabolism was also assessed...

Maternal physiologic stress during gestation has been reported to be associated with negative developmental outcomes, including intra-uterine growth restriction and reduced birth weight, which can impact postnatal development, behavior and health. The human fetus is partially protected from elevated cortisol exposure by placental 11 β-hydroxysteroid dehydrogenase type 2 (11β-HSD2), which oxidizes bioactive cortisol into bio-inactive cortisone. Importantly, despite the critical protective role hypothesized for 11β-HSD2, the onset of its placental expression has yet to be clearly established...

The placenta is a transient organ that plays a critical role in sustaining pregnancy and supporting fetal growth and nutrition. The placental epithelium is comprised of trophoblast cells. Trophoblast cells are the first cell type to differentiate during embryogenesis and ultimately diversify into a heterogeneous population of cells specializing in distinct functions essential for placentation. The emergence of the trophoblast lineage and subsequent specialization into distinct trophoblast sublineages is tightly regulated by transcription factors...

The fetus requires amino acids for the processes of protein synthesis, carbon accretion, oxidative metabolism, and biosynthesis, which ultimately determine growth rate in utero. The fetal supply of amino acids is critically dependent on the transport capacity of the placenta. System A amino acid transporters in the syncytiotrophoblast microvillous plasma membrane, directed toward maternal blood, actively accumulate amino acids, while system L exchangers mediate uptake of essential amino acids from the maternal circulation...

The placenta, one of the most important transient organs, forms by the apposition of fetal membranes and maternal tissues. Its role is to mediate physiological exchanges between mother and fetus. The word "apposition" covers a wide range of structural variations. It includes approximation, adhesion, interdigitation, or actual fusion between fetal and maternal tissues.(1) Formation of the placenta establishes hemotropic nutrition for the fetus: essential metabolites must be provided to maintain the growing fetus, and these must come to it via the maternal circulatory system...

The aim of the present study was to investigate the effect of programmed cell death 1 (PD-1) on osteosarcoma (OD) stem cells and T cells, and to determine their correlation. OS stem cells were sorted and identified from OS MG63 cells. Flow cytometry was used to detect the PD-1 expression of the OS tumor stem cell membrane surface. The expression of PD-1 mRNA was detected by reverse transcription-polymerase chain reaction (RT-PCR). MTT was used to detect the effect of PD-1 signals on T-cell proliferation. The results indicated that the cancer cells (cultured in DMEM medium containing 10% fetal bovine serum) exhibited clear proliferation within 1 week of cell culture, which showed their strong proliferation and aggressive ability...

BACKGROUND: Gestational diabetes mellitus (GDM), defined as any degree of glucose intolerance with onset during pregnancy, is increasing worldwide, mostly because obesity among women of reproductive age is continuously escalating. GDM is associated with adverse maternal and fetal outcomes. The aim of this article was to systematically review literature on the effectiveness of nutritional factors before or during pregnancy to prevent GDM. METHODS: We assessed the primary prevention of GDM through nutritional factors, as diet and supplements...
