Aim: To clarify whether maternal characteristics or laboratory parameters could help predict the onset of recurrent gestational diabetes mellitus (GDM). Methods: We enrolled 615 women with consecutive singleton deliveries at or after 28 GW from two perinatal medical centers between 2011 and 2019 and divided them into four groups according to whether they had GDM in the first and second pregnancies. The outcome of this study was to clarify the incidence and the predictors of recurrent GDM. Results: We found that among 72 women (11.7%) who had GDM during their first pregnancy, the rate of recurrent GDM was 47.2%. The 34 women (5.5%) with recurrent GDM gained significantly less weight in the first and second pregnancies and lost less weight between the first delivery and the second conception compared with those women without GDM in both pregnancies. Of women with GDM during the first pregnancy, 21 scored 2 or 3 (multiple) positive points on a 75‐g oral glucose tolerance test (OGTT) during their first pregnancies; the GDM recurrence rate among these women (66.7%) was significantly higher than that among the 51 women who scored 1 positive point (39.2%; p = 0.0411). During the first pregnancy, insulin administration therapy was significantly more frequent in women with recurrent GDM than in women without recurrent GDM (23.5% vs. 5.3%, p = 0.0396, respectively). Conclusion: A predictor of recurrent GDM onset was a score of 2 or 3 positive points on the OGTT during the first pregnancy. [ABSTRACT FROM AUTHOR]

Background: Currently, there is a disagreement between guidelines regarding platelet count cut-off values as a sign of maternal organ damage in pre-eclampsia; the American College of Obstetricians and Gynecologists guidelines state a cut-off value of < 100 × 109/L; however, the International Society for the Study of Hypertension in Pregnancy guidelines specify a cut-off of < 150 × 109/L. We evaluated the effect of mild thrombocytopenia: platelet count < 150 × 109/L and ≥ 100 × 109/L on clinical features of pre-eclampsia to examine whether mild thrombocytopenia reflects maternal organ damage in pre-eclampsia.Methods: A total of 264 women were enrolled in this study. Participants were divided into three groups based on platelet count levels at delivery: normal, ≥ 150 × 109/L; mild thrombocytopenia, < 150 × 109/L and ≥ 100 × 109/L; and severe thrombocytopenia, < 100 × 109/L. Risk of severe hypertension, utero-placental dysfunction, maternal organ damage, preterm delivery, and neonatal intensive care unit admission were analyzed based on platelet count levels. Estimated relative risk was calculated with a Poisson regression analysis with a robust error.Results: Platelet counts indicated normal levels in 189 patients, mild thrombocytopenia in 51 patients, and severe thrombocytopenia in 24 patients. The estimated relative risks of severe thrombocytopenia were 4.46 [95 % confidence interval, 2.59-7.68] for maternal organ damage except for thrombocytopenia, 1.61 [1.06-2.45] for preterm delivery < 34 gestational weeks, and 1.35 [1.06-1.73] for neonatal intensive care unit admission. On the other hand, the estimated relative risks of mild thrombocytopenia were 0.97 [0.41-2.26] for maternal organ damage except for thrombocytopenia, 0.91 [0.62-1.35] for preterm delivery < 34 gestational weeks, and 0.97 [0.76-1.24] for neonatal intensive care unit admission.Conclusions: Mild thrombocytopenia was not associated with severe features of pre-eclampsia and would not be suitable as a sign of maternal organ damage.

Aim: In Hokkaido, Japan, the number of people suffering from coronavirus disease 2019 (COVID‐19) is rapidly increased, and by the end of February 2020, there were already 70 confirmed cases of the disease. We investigated the safety of urgently initiated maternal telemedicine in preventing the spread of the coronavirus infection. Methods: This retrospective, single‐institution study examined maternal telemedicine at the department of obstetrics of the Hokkaido University Hospital from March 4 to April 2, 2020. The physicians remotely examined the pregnant women from their homes using a visual communication system which kept communication confidential, performed prenatal checkup and administered medical care according to their various blood pressures, weights and cardiotocograms. Results: Forty‐four pregnant women received a total of 67 telemedicine interventions. Thirty‐two pregnant women (73%) had complications, and 22 were primiparas (50%). Telemedicine interventions were provided 19 times at less than 26 weeks of gestation, 43 times between 26 and 36 weeks of gestation and 5 times after 37 weeks of gestation. There was one case with an abnormality diagnosed during the remote prenatal checkups, and the patient was hospitalized on the same day. However, there were no abnormal findings observed in mothers and children during the other 66 remote prenatal checkups and medical care. Conclusion: Maternal telemedicine can be safely conducted in pregnant women who are at risk of having an underlying disorder or fetal abnormality 1 month following the start of the attempt. It should be considered as a form of maternal medical care to prevent the spread of COVID‐19. [ABSTRACT FROM AUTHOR]

Objectives: To investigate the relationship between serum total protein (TP) levels and maternal/neonatal outcomes among pregnant women with preeclampsia.Study Design: TP was measured at preeclampsia diagnosis and delivery in 94 women with singleton pregnancies and preeclampsia as hypertension with proteinuria who delivered at ≥ 22 gestational weeks (GWs). As a control group, measurements were also made in 188 women with singleton pregnancies without hypertension and/or proteinuria.Main Outcome Measures: The relationship between serum TP levels and maternal outcomes.Results: Serum TP levels showed a significantly negative relationship with urine protein-to-creatinine (P/C) ratio at preeclampsia diagnosis and delivery. Serum TP levels at delivery in the preeclampsia group (53 ± 7 g/L) were lower than in the control group (61 ± 4 g/L, P < 0.0001). In each group, there was no relationship between the daily decrease in TP and the daily increase maternal body weight. However, there was a positive relationship between the daily increase in P/C ratio and the daily increase in maternal body weight in the preeclampsia group (P = 0.0021). Severe hypoproteinemia at preeclampsia diagnosis was a predictor of abruptio placentae (TP < 49 g/L; odds ratio, 21.3) and peripartum cardiomyopathy (TP < 45 g/L; odds ratio, 43.5). Furthermore, women with severe hypoproteinemia at delivery had higher morbidity due to pulmonary edema (TP < 55 g/L; odds ratio, 26.4) and central serous chorioretinopathy (TP < 42 g/L; odds ratio, 264).Conclusions: Serum TP levels and proteinuria severity at preeclampsia diagnosis and delivery showed a positive relationship and predicted poor maternal outcome.

Objectives: The present study aimed to determine the relationship between the severity of proteinuria and maternal/neonatal outcomes among women with preeclampsia.Study Design: Proteinuria severity was measured at preeclampsia diagnosis and at delivery in 94 women with preeclampsia (among 2904 women with singleton pregnancies, who delivered after 22 gestational weeks). Preeclampsia was defined as hypertension with proteinuria.Main Outcome Measures: Protein:creatinine (P/C) ratio to worse the maternal outcome was 4.8 among women with preeclampsia.Results: The frequencies of HELLP syndrome and maternal pulmonary edema in women with a P/C ratio ≥5.0 (35.5% and 35.5%, respectively) were significantly higher than those in women with a P/C ratio <5.0 (12.7%, P = 0.014 and 6.4%, P < 0.001, respectively). The best P/C ratio cutoff value to determine early-onset preeclampsia and early preterm birth (EPB) was 4.1 (P < 0.001 and P < 0.001, respectively). The best P/C ratio cutoff values to determine the interval between the preeclampsia diagnosis and delivery <7 days and the need to undergo cesarean section were 1.8 and 1.5, respectively. The best P/C ratio cutoff value to determine maternal pulmonary edema and central serous chorioretinopathy (CSC) was 4.8 (P = 0.020 and P = 0.014, respectively). Finally, the best P/C ratio cutoff values to determine EPB and maternal CSC in women with preeclampsia were 4.1 (odds ratio, 10.9; 95% confidence interval; 4.08 to 29.2, P < 0.0001) and 4.8 (odds ratio, 17.6; 95% confidence interval; 0.898 to 344, P = 0.0008), respectively, according to the multivariate analysis.Conclusions: A higher P/C ratio at delivery in women with preeclampsia might cause EPB and CSC.

Aim: This study was performed to evaluate maternal changes in laboratory characteristics after fetoscopic laser photocoagulation (FLP) for twin-to-twin transfusion syndrome (TTTS).Methods: A retrospective review was conducted among 30 women with monochorionic diamniotic twin pregnancy with TTTS who underwent FLP at 16-26 weeks of gestation. Maternal laboratory parameters were measured before and after FLP.Results: The pre-FLP mean hemoglobin level (10.0 g/dL), hematocrit level (30.0%), platelet count (229 × 109/mL), fibrinogen level (461 mg/dL), and antithrombin activity (96.8%) decreased after FLP (8.5 g/dL, 25.5%, 204 × 109/mL, 403 mg/dL, and 83.6%, respectively) and returned to normal spontaneously within 2 weeks (9.6 g/dL, 29.4%, 293 × 109/mL, 460 mg/dL, and 102.4%, respectively). The D-dimer level before FLP (2.41 μg/mL) increased after FLP (4.28 μg/mL), and the elevated level was maintained for 2 weeks (3.24 μg/mL). The symptomatic venous thromboembolism (VTE) was not detected after FLP in any of the 30 patients. However, one woman had pulmonary embolism after subsequent cesarean section.Conclusion: Changes in maternal anemia and coagulation/fibrinolysis after FLP for TTTS returned to normal spontaneously within 2 weeks. Maternal elevation of D-dimer level after FLP might be a warning indicator of VTE. [ABSTRACT FROM AUTHOR]

Objective: To examine whether laboratory parameters can predict the onset of recurrent hypertensive disorders of pregnancy (HDP).Methods: A retrospective study of 257 women with consecutive deliveries at a hospital in Sapporo, Japan, between 2009 and 2017. Women were divided into four groups according to whether or not they had HDP in the first and second peripartum periods (HDP-HPD, HDP-Non, Non-HDP, Non-Non). HDP was defined as gestational hypertension and/or proteinuria. Laboratory parameters measured on the day of or 1 day before delivery were compared between peripartum-1 and peripartum-2.Results: Frequency of HDP in peripartum-2 was higher among the 24 (9.3%) women with HPD in peripartum-1 (6/24, 25.0%) than among the 233 (90.7%) women without (3/233, 1.3%) (P<0.001). In peripartum-1, women with HDP had lower median antithrombin activity than those without (74% vs 89%, P=0.021). Antithrombin activity in peripartum-1 was also lower in the HDP-HDP (67%) than in the HDP-Non (79%) group (P=0.021). Antithrombin activities of 77% or less at the first delivery predicted HDP in peripartum-1 (P<0.001) and 70% or less predicted HDP in peripartum-2 (P=0.018).Conclusion: Women with HDP in peripartum-1 had a higher incidence of HDP recurrence. Low antithrombin before a first delivery might predict recurrent HDP in a second pregnancy. [ABSTRACT FROM AUTHOR]

Abstract: Objective: The circumflex iliac nodes distal to the external iliac nodes (CINDEINs) are included in the regional lymph nodes that are commonly dissected during systematic lymphadenectomy for ovarian cancer. Because in recent years CINDEIN dissection has been reported as a significant risk factor for postoperative lower limb lymphedema, we investigated the validity of omitting the CINDEIN dissection by evaluating the distribution pattern of positive lymph nodes in ovarian cancer, in order to improve postoperative quality of life (QOL). Methods: We performed a retrospective chart review of 142 patients with ovarian cancer who had undergone systematic lymphadenectomy between 1995 and 2010. We assessed the distribution pattern of lymph node metastasis and the presence of CINDEIN metastasis according to the pT classification (pT1, pT2, and pT3). Results: Of the 142 patients, 71, 21, and 50 were classified into pT1, pT2, and pT3, respectively. The lymph nodes most frequently involved were the para-aortic lymph nodes superior to the mesenteric artery (14%), followed by the obturator nodes (11%), the internal iliac nodes (9.4%), and the common iliac nodes (7.4%). Although the frequency of CINDEIN metastasis was 5.3% (6 of 114 cases with CINDEIN dissection), no metastasis to the CINDEINs was observed in pT1 patients. Conclusions: It may be acceptable to omit CINDEIN dissection during surgery for pT1 ovarian cancer in view of postoperative QOL. [Copyright &y& Elsevier]
