| Abstract | Thrombosis in decidual vessels is one of the mechanisms of pregnancy loss. However, few studies have assessed the relation between platelet activation, which is known to cause of thrombosis, and recurrent pregnancy loss (RPL). We investigated platelet activation in women with RPL compared to controls by measuring plasma levels of platelet factor 4 (PF4) and β-thromboglobulin (βTG), and assessed correlations between PF4/βTG and coagulative risk factors associated with RPL. The study group included 135 women who had experienced two or more consecutive pregnancy losses. The control group included 28 age-matched healthy women who had never experienced pregnancy loss. PF4 and βTG plasma levels were significantly higher in the women with RPL than controls (PF4: 14.0 [8.0-20.0] vs. 9.0 [6.0-12.0] ng/ml, p=0.043; βTG: 42.0 [24.3-59.8] vs. 31.5 [26.6-36.4] ng/ml, p=0.002). There was a significant association between βTG and anti-phosphatidylethanolamine antibody immunoglobulin M (aPE IgM) (p=0.048). Among the women with RPL, 18 of those who were positive for PF4 (45%) and 18 of those who were positive for βTG (37%) were negative for all known coagulative risk factors associated with RPL. Measurements of PF4 and βTG may be important because they help identify women who are at risk of RPL. |

| Abstract | This study aimed to determine whether the risk conferred by gynecologic cancer (GC) as second primary cancer (SPC) differs from that associated with GC as first primary cancer (FPC). We investigated the correlations between FPC/SPC and the characteristics and prognoses of 1,645 GC patients (701 with cervical cancer [CC], 641 with endometrial cancer [EM], and 303 with ovarian cancer [OV]). The χ2 test and the Kaplan–Meier method were used to determine whether FPC/SPC and the characteristics and prognoses of GC patients. Of the SPC patients, 26 (3.7%) had CC, 53 (8.3%) had EM, and 31 (10.2%) had OV. The most common previous cancer type in SPC of GC patients was breast cancer, which was observed in 13 patients (50.0%) with CC, 23 (43.4%) with EM, and 16 (51.6%) with OV. In all patients with CC, EM, and OV as SPC, the stage was significantly associated with recurrence. There were no significant differences in the morbidity or mortality of CC, EM, or OV patients between those with FPC and those with SPC. The risk of SPC development in GC patients varied, ranging from 3.5% (CC) to 10.3% (OV) of patients. |

| Abstract | We experienced a case of advanced maternal age in which a fetus was found to be positive for trisomy 18 at re-examination following indeterminate non-invasive prenatal genetic testing (NIPT), the amniotic fluid chromosomal test revealed a normal karyotype, and confined placental mosaicism (CPM) was observed in an SNP microarray analysis of the placenta. The child was born with no defects or complications. In the present case, the result of the original NIPT at week 15 of pregnancy was indeterminate and the subsequent re-examination result was positive; since the definitive normal diagnosis was not reported until the latter half of week 21, the pregnant patient was subjected to psychological stress for a long period of time. The problem with NIPT is that most of the fetus-derived cell-free DNA in the maternal blood is not derived directly from the fetus but from the villus cells of the placenta, leading to indefinite diagnoses; for that reason, the pregnant patient was subjected to psychological stress for a long period of time. Of the 18,251 cases undergoing NIPT in the past 2 years in Japan, 51 had indeterminate results; this was the second case in which a subsequent re-examination gave a positive result for trisomy 18. |

| Abstract | Although gestational hypertension (GH) is thought to be different from preeclampsia (PE), in Japan GH and PE are usually treated as the same disease (i.e., pregnancy-induced hypertension). Here we sought to determine whether there are any differences in fetal growth and maternal kidney function between pregnancies with PE and those with GH. We retrospectively analyzed 61 GH patients and 60 PE patients with singleton pregnancies who delivered at Okayama University Hospital (2008-2015). We compared maternal and perinatal outcomes and maternal kidney function parameters between the GH and PE pregnancies. The mean values of maternal age (p=0.01), gestational age at delivery (p<0.0001), placental weight (p=0.002), birth weight and height (p<0.0001, p=0.0001), and head circumference standard deviation score (p=0.007) of newborns of the GH group were significantly higher than those of the PE group. The duration until termination of PE or GH was not significantly correlated with kidney function. The birth weight percentile was significantly correlated with kidney function in PE but not GH. However, GH patients with poor kidney function and small-for-gestational age infants showed perinatal outcomes similar to those of the PE group. Monitoring kidney function is thus important for determining the severity of PE and GH. |

| Abstract | Preeclampsia may be due to an excess of circulating anti-angiogenic growth factors derived from the placenta, but metabolic syndrome-like disorders may also set off a cascade of placental and systemic inflammation and oxidative stress. We present a case of severe superimposed preeclampsia with obesity, diabetes and a mild imbalance of angiogenic factors, in which diet therapy ameliorated the preeclamptic signs while improving the adiponectin level. A 41-year-old pregnant woman with obesity and diabetes was referred to our hospital because of severe proteinuria and hypertension at 22 weeks of gestation. After administration of insulin and hydralazine with diet therapy, her hypertension and proteinuria were ameliorated with a 15-kg weight loss. Her adiponectin level was low and her leptin level was high, but her angiogenic factor levels were within the normal ranges for pregnant women at admission. The diet therapy ameliorated her hypertension and proteinuria while improving her adiponectin level as she achieved weight loss. This case suggests that diet therapy for obese preeclampsia patients with a mild imbalance of anti-and pro-angiogenic factors may play an important role in managing preeclampsia. Measurements of maternal adipocytokines and angiogenic factors may be important to distinguish the main cause of preeclampsia, i.e., poor placentation or maternal constitutional factors, for managing preeclampsia in patients with obesity. |

| Abstract | It has been reported that prolactin (PRL) is cleaved to 14 or 16 kDa fragments by cathepsin D in vitro and in vivo, and that such fragments exhibit antiangiogenic and proapoptotic properties. The aim of this study was to investigate the relationship between pregnancy induced hypertension (PIH) and the placental expression of antiangiogenic PRL fragments and cathepsin D. Placental expression of PRL fragments and cathepsin D was evaluated by Western blot analysis in a group of 9 pregnant women consisting of 5 normal pregnancies and 4 severe PIH cases. Antiangiogenic PRL fragments were detected in 4 placental samples from all PIH cases but not detected in those from normal pregnancies (p0.05). The expression of cathepsin D in PIH placentas was significantly lower than that in those without PIH (p0.05), while the placental expression of procathepsin D was significantly greater in PIH cases than in the normal pregnancies (p0.05). These data suggest that antiangiogenic PRL fragments in the placenta may be present only in PIH cases, and that PRL fragments in the placenta might be implicated in the pathophysiology of PIH. |

| Abstract | <p>Ciliary neurotrophic factor (CNTF) has been shown to decrease food intake in mouse models of obesity and to improve insulin sensitivity. It is well known that tight regulation of glucose metabolism is essential for successful gestational outcomes (e.g. fetal growth), and that abnormal insulin resistance is associated with preeclampsia (PE). To investigate the possibility that CNTF might be involved in the regulation of insulin resistance during pregnancy, circulating levels of CNTF were assessed in non-pregnant, normal pregnant, postpartum, and pregnant women with PE. Sera from healthy non-pregnant women (n10), pregnant women (n30:1st trimester;n10, 2nd trimester n10;3rd trimester;n10), postpartum women (n10), and patients with PE (n11) were studied with Western blotting. Circulating CNTF was detected by Western blotting, and the levels of CNTF in pregnant women were decreased as compared with those in non-pregnant women, and tended to decrease as pregnancy progressed. A significant decrease was found in PE as compared with normal pregnancy. Circulating CNTF might be associated with physiological and abnormal insulin resistance during pregnancy.</p> |

| Abstract | <p>Surfactant treatment in infants with respiratory distress syndrome (RDS) has decreased neonatal mortality. With the advent of this therapy, it has become important to predict accurately the fetal lung maturity of a fetus before delivery. We evaluated the stable microbubble test (SMT), surfactant protein-A (SP-A) and hepatocyte growth factor (HGF) in amniotic fluid as predicting markers for RDS. Of 55 amniotic fluid samples obtained by amniocentesis from women less than 37 weeks pregnant, the SMT values were as follows: sensitivity 76.5%, specificity 84.2%, positive predictive value 68.4%, negative predictive value 88.9% and overall accuracy 81.8%. For SP-A, the values were 88.2%, 65.8%, 53.6%, 92.6% and 72.7%, respectively. If we used both SMT and SP-A, we could diagnose with 100% accuracy that a case with measurements of SMT > or = 2 and SP-A > or = 420 ng/ml would not complicate with RDS (24/24). However, the RDS diagnostic accuracy of HGF does not equal to those of SMT and SP-A levels. We concluded that the rapidity, simplicity and reliability of SMT was very useful during 24-36 weeks of gestation as a bedside procedure to predict fetuses likely to develop RDS. We also noted the additive effect of SP-A in improving the accuracy of lung maturity diagnosis.</p> |

| Abstract | <p>It is well known that antecedent term delivery and metastasis to sites other than the lungs and vagina are high risk factors for patients with gestational trophoblastic neoplasia. Here we report on a patient with choriocarcinoma who presented with brain and lung metastases after term delivery and was treated by EMA-CO chemotherapy. A 31-year-old woman delivered a healthy infant at term. Frequent episodes of hemoptysis occurred beginning 3 weeks after the delivery. On admission to our hospital, she had lesions in the uterus, lungs and brain as well as motor aphasia and hemiplagia. The pretreatment beta-hCG level was 21,000 ng/ml and the WHO score was 16 (high-risk group). The EMA-CO regimen was administrated as first-line chemotherapy and the patient achieved complete remission after 7 courses. Treatment was terminated after 11 courses and maintained with etoposide (25 mg/day) for 6 months. The patient has remained in complete remission for more than 16 years without other adjuvant therapies. We believe that EMA-CO can currently be considered the regimen of first choice for most high-risk patients with gestational trophoblastic neoplasia in view of its effectiveness and excellent tolerability.</p> |
