Positive correlation between maternal serum coenzyme Q10 levels and infant birth weight.
Summary of "Positive correlation between maternal serum coenzyme Q10 levels and infant birth weight."
The purpose of this study was to examine the relationship between the level of maternal serum coenzyme Q10 (CoQ10), which is a lipid-soluble antioxidant, maternal body weight gain, fat mass gain, and infant birth weight. A longitudinal observational study was conducted with 50 healthy pregnant women (average age: 31.1 years, average body mass index (BMI): 21.3 kg/m(2) at prepregnancy) at each trimester. CoQ10 levels were measured by high performance liquid chromatography. Maternal weight and body composition were measured by a bioelectrical impedance analysis. The CoQ10 levels significantly increased throughout pregnancy from the first trimester to the third trimester (P < 0.001), and correlated with not only the serum cholesterol levels (P < 0.01) but also with the serum acetoacetic acid levels (P < 0.05) in the third trimester. The CoQ10 levels correlated with the maternal weight gain (P < 0.05) and fat mass gain (P < 0.05) from the second to the third trimester, after adjusting for lipid markers, age, and smoking habits. The level of CoQ10 during the third trimester was also significantly associated with the infant birth weight (P < 0.05) after adjusting for gestational age, maternal prepregnancy BMI, and smoking habits. Therefore, it is concluded that the level of maternal CoQ10 is positively associated with fetal growth, balancing rapid metabolic changes in the last half of a normal pregnancy.

Hyperthyroxinemia, Familial Dysalbuminemic
An inherited autosomal dominant trait characterized by abnormally elevated levels of total serum THYROXINE; (T4) in euthyroid patients with abnormal SERUM ALBUMIN that binds T4 with enhanced affinity. The serum levels of free T4, free T3, and TSH are normal. It is one of several T4 abnormalities produced by non-thyroid disorder. This condition is due to mutations of the ALB gene on CHROMOSOME 4.
The first alpha-globulins to appear in mammalian sera during development of the embryo and the dominant serum proteins in early embryonic life. They reappear in the adult serum during certain pathologic states, primarily hepatocellular carcinoma. They may also be elevated in the amniotic fluid and maternal serum during pregnancy in ANENCEPHALY.
Maternal Nutritional Physiological Phenomena
Nutrition of a mother which affects the health of the FETUS and INFANT as well as herself.
A tetrameric protein, molecular weight between 50,000 and 70,000, consisting of 4 equal chains, and migrating on electrophoresis in 3 fractions more mobile than serum albumin. Its concentration ranges from 7 to 33 per cent in the serum, but levels decrease in liver disease.
Demographic and epidemiologic changes that have occurred in the last five decades in many developing countries and that are characterized by major growth in the number and proportion of middle-aged and elderly persons and in the frequency of the diseases that occur in these age groups. The health transition is the result of efforts to improve maternal and child health via primary care and outreach services and such efforts have been responsible for a decrease in the birth rate; reduced maternal mortality; improved preventive services; reduced infant mortality, and the increased life expectancy that defines the transition.
