Preterm birth (PTB) is a leading cause of neonatal death worldwide. Intrauterine and systemic infection and inflammation cause 30-40% of spontaneous preterm labor (PTL), which precedes PTB. Although antibody production is a major immune defense mechanism against infection, and B cell dysfunction has been implicated in pregnancy complications associated with PTL, the functions of B cells in pregnancy are not well known. We found that choriodecidua of women undergoing spontaneous PTL harbored functionally altered B cell populations...

Preterm labor is often a sudden event that impacts significantly on the health of the premature infant and on parenting behaviors. The prognosis for premature infants correlates positively with the effectiveness of parenting. Therefore, encouraging parental functions is important. The present paper reviews the literature on the concept of family-centered care in the contexts of premature-infant health problems, assesses the impacts of preterm birth on the parental role, and assesses the influences of parental dysfunction...

Preterm labor (PTL) accounts for almost 11% of deliveries, and is a major cause of neonatal morbidity and mortality. T regulatory (Treg) cells may prevent fetal rejection by the maternal immune system under the influence of progesterone. Case control study was conducted to determine Treg cells, IL-10, TGF-β, and membrane progesterone receptorα (mPRα) in the maternal-fetal interface (placenta), including eight pregnant women with threatened PTL (study group) and 16 normal-delivery women (control group). Comparing study group versus control, mean gestational age of delivery differed significantly (p = 0...

Preterm birth is a leading cause of neonatal morbidity and mortality. Although microbial invasion of the amniotic cavity (MIAC) is associated with the majority of early preterm births, the temporal events that occur during MIAC and preterm labor are not known. Group B Streptococci (GBS) are β-hemolytic, gram-positive bacteria, which commonly colonize the vagina but have been recovered from the amniotic fluid in preterm birth cases. To understand temporal events that occur during MIAC, we utilized a unique chronically catheterized nonhuman primate model that closely emulates human pregnancy...

Diabetes in pregnancy is associated with higher rates of miscarriage, pre-eclampsia, preterm labor, and fetal malformation. To prevent these obstetric and perinatal complications, women with diabetes have to control levels of blood sugar, both prior to and during pregnancy. Thus, individualized medical nutrition therapy for each stage of pregnancy is essential. We provided in-depth medical nutrition therapy to a 38-year-old pregnant woman with diabetes at all stages of pregnancy up to delivery. She underwent radiation therapy after surgery for breast cancer and was diagnosed with diabetes...

Spontaneous preterm labor occurs in two subsets of patients with sterile intra-amniotic inflammation, which is induced by alarmins such as high-mobility group box-1 (HMGB1). Inflammasomes are also implicated in the process of spontaneous preterm labor with acute chorioamnionitis. Therefore, we investigated whether HMGB1 initiates an inflammasome-associated inflammatory response in the chorioamniotic membranes. Incubation of the chorioamniotic membranes with HMGB1: 1) induced the release of mature IL-1beta and IL-6; 2) upregulated the mRNA expression of the pro-inflammatory mediators NFKB1, IL6, TNF, IL1A, IFNG, and HMGB1 receptors RAGE and TLR2; 3) upregulated the mRNA expression of the inflammasome components NLRP3 and AIM2, and NOD proteins (NOD1 and NOD2); 4) increased the protein concentrations of NLRP3 and NOD2; 5) increased the concentration of caspase-1 and the quantity of its active form (p20); and 6) upregulated the mRNA expression and active form of MMP-9...
