Primary leiomyosarcoma of the uterine cervix: an unusual case and critical appraisal.

Leiomyosarcomas of the uterine cervix are rare, mostly occurring in perimenopausal women. Diagnosis is based on pathology and immunohistochemistry. Surgery with a total abdominal hysterectomy and bilateral salpingo-oophorectomy remains the standard. A female patient in her 60s presented with heavy postmenopausal bleeding. Vaginal ultrasound scan and magnetic resonance imaging showed a large strongly vascularized cervical mass with features suspicious of sarcomatous degeneration. Positron Emission Tomography-Computed Tomography (PET-CT) did not reveal any evidence of metastases nor lymphadenopathy, but presence of right hydronephrosis. An abdominal hysterectomy with bilateral salpingo-oophorectomy, and end-to-end anastomosis of the right ureter, was performed. Pathology showed an International Federation of Gynecology and Obstetrics (FIGO)-stage 1B leiomyosarcoma of the uterine cervix. No adjuvant treatment was given. Adjuvant radiotherapy reduces the risk of recurrence but no survival impact. The benefit of adjuvant chemotherapy is questionable given the lack of randomized trials. Multidisciplinary research concerning molecular alterations of the disease is required to determine optimal management strategies with potential novel molecular therapies.

Normal glucose tolerant women with low glycemia during the oral glucose tolerance test have a higher risk to deliver a low birth weight infant.

Background: Data are limited on pregnancy outcomes of normal glucose tolerant (NGT) women with a low glycemic value measured during the 75g oral glucose tolerance test (OGTT). Our aim was to evaluate maternal characteristics and pregnancy outcomes of NGT women with low glycemia measured at fasting, 1-hour or 2-hour OGTT. Methods: The Belgian Diabetes in Pregnancy-N study was a multicentric prospective cohort study with 1841 pregnant women receiving an OGTT to screen for gestational diabetes (GDM). We compared the characteristics and pregnancy outcomes in NGT women according to different groups [(<3.9mmol/L), (3.9-4.2mmol/L), (4.25-4.4mmol/L) and (>4.4mmol/L)] of lowest glycemia measured during the OGTT. Pregnancy outcomes were adjusted for confounding factors such as body mass index (BMI) and gestational weight gain. Results: Of all NGT women, 10.7% (172) had low glycemia (<3.9 mmol/L) during the OGTT. Women in the lowest glycemic group (<3.9mmol/L) during the OGTT had compared to women in highest glycemic group (>4.4mmol/L, 29.9%, n=482), a better metabolic profile with a lower BMI, less insulin resistance and better beta-cell function. However, women in the lowest glycemic group had more often inadequate gestational weight gain [51.1% (67) vs. 29.5% (123); p<0.001]. Compared to the highest glycemia group, women in the lowest group had more often a birth weight <2.5Kg [adjusted OR 3.41, 95% CI (1.17-9.92); p=0.025]. Conclusion: Women with a glycemic value <3.9 mmol/L during the OGTT have a higher risk for a neonate with birth weight < 2.5Kg, which remained significant after adjustment for BMI and gestational weight gain.

Low Gestational Weight Gain in Women With Gestational Diabetes Is Safe With Better Metabolic Profile Postpartum.

CONTEXT: More data are needed on the potential benefits and risks of gestational weight gain (GWG) less than recommended and excessive GWG in women with gestational diabetes (GDM) compared to women with normal glucose tolerance (NGT) during pregnancy. OBJECTIVE: This work aimed to evaluate association of gestational weight gain (GWG) as low, within, or above (excessive) according to Institute of Medicine (IOM) guidelines, with pregnancy outcomes in women with gestational diabetes (GDM) and normal glucose tolerance (NGT). METHODS: This prospective cohort study included 7 Belgian hospitals and 1843 women receiving universal GDM screening with a 75-g oral glucose tolerance test. Pregnancy outcomes and postpartum characteristics were the main outcome measures. RESULTS: Women with GDM and low GWG (n = 97, 52.4%) had similar rates of small-for-gestational age infants and preterm delivery, were less often overweight or obese postpartum (35.7% [30] vs 56.5% [26]; P < .022) and less often had postpartum weight retention (PPWR) (48.8% [41] vs 87.9% [40]; P < .001) compared to GWG within range (n = 58, 31.3%). GDM with excessive GWG (n = 30, 16.2%) more often had neonatal hypoglycemia (30.8% (8) vs 5.9% [3], aOR 7.15; 95% CI, 1.52-33.63; P = .013) compared to GWG within range. NGT with excessive GWG (28.3% [383]) more often had instrumental delivery (15.9% [61] vs 11.9% [64], aOR 1.53; 95% CI, 1.03-2.27; P = .035) and more large-for-gestational age infants (19.3% [74] vs 10.4% [56], aOR 1.67; 95% CI, 1.13-2.47; P = .012) compared to GWG within range. CONCLUSION: GWG below IOM guidelines occurred frequently in GDM women, without increased risk for adverse pregnancy outcomes and with better metabolic profile postpartum. Excessive GWG was associated with increased risk for neonatal hypoglycemia and worse metabolic profile postpartum in women with GDM, and with higher rates of LGA and instrumental delivery in NGT women.

Type 1 diabetes-related autoimmune antibodies in women with gestational diabetes mellitus and the long-term risk for glucose intolerance.

Aims: To characterize women with gestational diabetes mellitus (GDM) positive for type 1 diabetes-related autoimmune antibodies (T1D-related autoantibodies) in pregnancy and to evaluate their risk for long-term glucose intolerance. Methods: In a multi-centric prospective cohort study with 1843 women receiving universal screening for GDM with a 75 g oral glucose tolerance test (OGTT), autoantibodies were measured in women with GDM: insulin autoantibodies (IAA), islet cell antibodies (ICA), insulinoma-associated protein-2 antibodies (IA-2A) and glutamic acid decarboxylase antibodies (GADA). Long-term follow-up ( ± 4.6 years after delivery) with a 75 g OGTT and re-measurement of autoantibodies was done in women with a history of GDM and autoantibody positivity in pregnancy. Results: Of all women with GDM (231), 80.5% (186) received autoantibody measurement at a mean of 26.2 weeks in pregnancy, of which 8.1% (15) had one positive antibody (seven with IAA, two with ICA, four with IA-2A and two with GADA). Characteristics in pregnancy were similar but compared to women without autoantibodies, women with autoantibodies had more often gestational hypertension [33.3% (5) vs. 1.7% (3), p<0.001] and more often neonatal hypoglycemia [40.0% (6) vs. 12.5% (19), p=0.012]. Among 14 of the 15 autoantibody positive women with an early postpartum OGTT, two had impaired fasting glucose (IFG). Of the 12 women with long-term follow-up data, four tested again positive for T1D-related autoantibodies (three positive for IA-2A and one positive for ICA and IAA). Five women were glucose intolerant at the long-term follow-up of which two had IA-2A (one had IFG and one had T1D) and three without autoantibodies. There were no significant differences in long-term characteristics between women with and without autoantibodies postpartum. Conclusions: Systematic screening for T1D-related autoantibodies in GDM does not seem warranted since the low positivity rate for autoantibodies in pregnancy and postpartum. At 4.6 years postpartum, five out of 12 women were glucose intolerant but only two still had autoantibodies. In women with clinically significant increased autoantibody levels during pregnancy, postpartum autoantibody re-measurement seems useful since the high risk for further increase of autoantibody levels.

Higher Thyroid fT3-to-fT4 Ratio Is Associated with Gestational Diabetes Mellitus and Adverse Pregnancy Outcomes.

Aim: To determine the association between thyroid function and the risk of developing gestational diabetes mellitus (GDM) and adverse pregnancy outcomes. Methods: This case−control study was a sub-analysis of the BEDIP-N study, in which 199 GDM women were matched for age and body mass index with 398 controls. Thyroid-stimulating hormone (TSH), free thyroxine (fT4), free triiodothyronine (fT3), and thyroid peroxidase (TPO) antibodies were measured at 6−14 weeks and 26−28 weeks during pregnancy. TSH and fT4 were also measured in early postpartum in GDM women. Results: The fT3-to-fT4 ratio at 26−28 weeks was positively associated with GDM risk with an adjusted odds ratio (aOR for smoking, education, parity, ethnicity, gestational weight gain, and (family) history of diabetes or GDM) of 2.12 (95% CI 1.07; 4.23), comparing the highest with the lowest tertile. Higher fT3 levels and a higher fT3-to-fT4 ratio were associated with a less favorable metabolic profile with higher BMI and more insulin resistance during pregnancy and postpartum. Women in the upper fT3 tertile and the upper fT3-to-fT4 ratio had a higher rate of preeclampsia [4.6% (10) vs. 1.0% (2), p = 0.040, and 4.4% (9) vs. 0.5% (1), p = 0.020], gestational hypertension [8.3% (18) vs. 3.1% (6), p = 0.034 and 8.9% (18) vs. 2.0% (4), p = 0.003], and caesarean sections [29.4% (63) vs. 16.1% (31), p = 0.002 and 32.2% (65) vs. 12.7% (25), p < 0.001]. Conclusion: A higher fT3-to-fT4 ratio late into pregnancy was associated with GDM, adverse pregnancy outcomes, and an adverse metabolic profile in early postpartum.

Fasting plasma glucose level to guide the need for an OGTT to screen for gestational diabetes mellitus.

AIMS: To determine the fasting plasma glucose (FPG) level at which an oral glucose tolerance test (OGTT) could be avoided to screen for gestational diabetes (GDM) and to evaluate the characteristics of women across this FPG threshold. METHODS: A multi-centric prospective cohort study with 1843 women receiving universal screening for GDM with a 75 g OGTT. RESULTS: In the total population, GDM prevalence was 12.5% (231). A FPG < 78 mg/dL was the cut-off with best trade-off to limit the number of missed GDM cases [44 (19.0%)] with a negative predictive value of 97.3% (95% CI 96.5-98.0) for GDM, while avoiding 52.2% OGTTs. Compared to GDM with FPG ≥ 78 mg/dL [187 (81.0%)], GDM women with FPG < 78 mg/dL had a significantly lower BMI (27.1 ± 4.5 vs. 29.6 ± 5.2 kg/m2, p = 0.003), less insulin resistance [Matsuda: 0.4 (0.4-0.7) vs. 0.3 (0.2-0.5), p < 0.001] and better ß-cell function [ISSI-2: 0.13 (0.08-0.25) vs. 0.09 (0.04-0.15), p = 0.004]. Compared to NGT women (1612) with FPG ≥ 78 mg/dL [846 (52.5%)], NGT with FPG < 78 mg/dL [766 (47.5%)] had a significantly lower BMI (26.0 ± 3.9 vs. 27.8 ± 4.7 kg/m2, p < 0.001), less insulin resistance [Matsuda: 0.7 (0.5-0.9) vs. 0.5 (0.4-0.7), p < 0.001], better ß-cell function [ISSI-2: 0.17 (0.10-0.30) vs. 0.12 (0.07-0.21), p < 0.001], and less often large-for-gestational age infants [9.2 (70) vs. 16.2% (136), p < 0.001]. CONCLUSIONS: FPG < 78 mg/dL can be used to limit the number of OGTTs when screening for GDM. Women with FPG < 78 mg/dL had a better metabolic profile and in NGT women also less fetal overgrowth.

Preference of Women for Gestational Diabetes Screening Method According to Tolerance of Tests and Population Characteristics.

Aims: To determine the preferred method of screening for gestational diabetes mellitus (GDM). Methods: 1804 women from a prospective study (NCT02036619) received a glucose challenge test (GCT) and 75g oral glucose tolerance test (OGTT) between 24-28 weeks. Tolerance of screening tests and preference for screening strategy (two-step screening strategy with GCT compared to one-step screening strategy with OGTT) were evaluated by a self-designed questionnaire at the time of the GCT and OGTT. Results: Compared to women who preferred one-step screening [26.2% (472)], women who preferred two-step screening [46.3% (834)] were less often from a minor ethnic background [6.0% (50) vs. 10.7% (50), p=0.003], had less often a previous history of GDM [7.3% (29) vs. 13.8% (32), p=0.008], were less often overweight or obese [respectively 23.1% (50) vs. 24.8% (116), p<0.001 and 7.9% (66) vs. 18.2% (85), p<0.001], were less insulin resistant in early pregnancy (HOMA-IR 8.9 (6.4-12.3) vs. 9.9 (7.2-14.2), p<0.001], and pregnancy outcomes were similar except for fewer labor inductions and emergency cesarean sections [respectively 26.6% (198) vs. 32.5% (137), p=0.031 and 8.2% (68) vs. 13.0% (61), p=0.005]. Women who preferred two-step screening had more often complaints of the OGTT compared to women who preferred one-step screening [50.4% (420) vs. 40.3% (190), p<0.001]. Conclusions: A two-step GDM screening involving a GCT and subsequent OGTT is the preferred GDM screening strategy. Women with a more adverse metabolic profile preferred one-step screening with OGTT while women preferring two-step screening had a better metabolic profile and more discomfort of the OGTT. The preference for the GDM screening method is in line with the recommended Flemish modified two-step screening method, in which women at higher risk for GDM are recommended a one-step screening strategy with an OGTT, while women without these risk factors, are offered a two-step screening strategy with GCT. Clinical Trial Registration: NCT02036619 https://clinicaltrials.gov/ct2/show/NCT02036619.

Antenatal Depression and Risk of Gestational Diabetes, Adverse Pregnancy Outcomes, and Postpartum Quality of Life.

AIMS: To determine the impact of depressive symptoms on pregnancy outcomes and postpartum quality of life in women with gestational diabetes mellitus (GDM) and normal glucose tolerance (NGT). METHODS: 1843 women from a prospective cohort study received universal GDM screening with an oral glucose tolerance test (OGTT). The Center for Epidemiologic Studies-Depression questionnaire was completed before GDM diagnosis was communicated and in GDM women in early postpartum. All participants completed the 36-Item Short Form Health Survey (SF-36) health survey postpartum. RESULTS: Women who developed GDM (231; 12.5%) had significantly more often depressive symptoms than NGT (1612; 87.5%) women [21.3% (48) vs 15.1% (239), odds ratio (OR) 1.52, 95% confidence interval (CI) (1.08-2.16), P = 0.017]. Compared to GDM women without depressive symptoms, depressed GDM women attended less often the postpartum OGTT [68.7% (33) vs 87.6% (155), P = 0.002], remained more often depressed [37.1% (13) vs 12.4% (19), P < 0.001], and had lower SF-36 scores postpartum. There were no significant differences in pregnancy outcomes between both groups. Rates of labor inductions were significantly higher in the NGT group with depressive symptoms compared to the nondepressed NGT group [31.7% (75) vs 24.7% (330), adjusted OR (aOR) 1.40, 95% CI (1.01-1.93), P = 0.041]. NGT women with depressive symptoms had lower SF-36 scores (P < 0.001) postpartum compared to nondepressed NGT women. CONCLUSIONS: Women with antenatal symptoms of depression develop more often GDM. GDM women with depressive symptoms remain more often depressed postpartum with lower quality of life. NGT women with depressive symptoms have higher rates of labor inductions and lower quality of life postpartum compared to nondepressed NGT women.

Women with Mild Fasting Hyperglycemia in Early Pregnancy Have More Neonatal Intensive Care Admissions.

AIMS: To determine impact of mild fasting hyperglycemia in early pregnancy (fasting plasma glucose [FPG] 5.1-5.5 mmol/L) on pregnancy outcomes. METHODS: We measured FPG at 11.9 ± 1.8 weeks in 2006 women from a prospective cohort study. Women with FPG ≥5.6 mmol/L (19) received treatment and were excluded from further analyses. A total of 1838 women with FPG <5.6 mmol/L received a 75 g oral glucose tolerance test (OGTT) between 24 and 28 weeks of pregnancy. RESULTS: Of all participants, 78 (4.2%) had FPG 5.1 to 5.5 mmol/L in early pregnancy, of which 49 had a normal OGTT later in pregnancy (high fasting normal glucose tolerance [NGT] group). Compared with the NGT group with FPG <5.1 mmol/L in early pregnancy (low fasting NGT group, n = 1560), the high fasting NGT group had a higher body mass index (BMI), higher insulin resistance with more impaired insulin secretion and higher FPG and 30 minute glucose levels on the OGTT. The admission rate to neonatal intensive care unit (NICU) was significantly higher in the high fasting NGT group than in the low fasting NGT group (20.4% [10] vs 9.3% [143], P = .009), with no difference in duration (7.0 ± 8.6 vs 8.4 ± 14.3 days, P = .849) or indication for NICU admission between both groups. The admission rate to NICU remained significantly higher (odds ratio 2.47; 95% confidence interval 1.18-5.19, P = .017) after adjustment for age, BMI, and glucose levels at the OGTT. CONCLUSIONS: When provision of an OGTT is limited such as in the Covid-19 pandemic, using FPG in early pregnancy could be an easy alternative to determine who is at increased risk for adverse pregnancy outcomes.

Estimating the risk of gestational diabetes mellitus based on the 2013 WHO criteria: a prediction model based on clinical and biochemical variables in early pregnancy.

AIMS: We aimed to develop a prediction model based on clinical and biochemical variables for gestational diabetes mellitus (GDM) based on the 2013 World Health Organization (WHO) criteria. METHODS: A total of 1843 women from a Belgian multi-centric prospective cohort study underwent universal screening for GDM. Using multivariable logistic regression analysis, a model to predict GDM was developed based on variables from early pregnancy. The performance of the model was assessed by receiver-operating characteristic (AUC) analysis. To account for over-optimism, an eightfold cross-validation was performed. The accuracy was compared with two validated models (van Leeuwen and Teede). RESULTS: A history with a first degree relative with diabetes, a history of smoking before pregnancy, a history of GDM, Asian origin, age, height and BMI were independent predictors for GDM with an AUC of 0.72 [95% confidence interval (CI) 0.69-0.76)]; after cross-validation, the AUC was 0.68 (95% CI 0.64-0.72). Adding biochemical variables, a history of a first degree relative with diabetes, a history of GDM, non-Caucasian origin, age, height, weight, fasting plasma glucose, triglycerides and HbA1c were independent predictors for GDM, with an AUC of the model of 0.76 (95% CI 0.72-0.79); after cross-validation, the AUC was 0.72 (95% CI 0.66-0.78), compared to an AUC of 0.67 (95% CI 0.63-0.71) using the van Leeuwen model and an AUC of 0.66 (95% CI 0.62-0.70) using the Teede model. CONCLUSIONS: A model based on easy to use variables in early pregnancy has a moderate accuracy to predict GDM based on the 2013 WHO criteria.

Characteristics and pregnancy outcomes across gestational diabetes mellitus subtypes based on insulin resistance.

AIMS/HYPOTHESIS: This study aimed to determine the characteristics and pregnancy outcomes across different subtypes of gestational diabetes mellitus (GDM) based on insulin resistance. METHODS: GDM subtypes were defined in 1813 pregnant women from a multicentre prospective cohort study, stratified according to insulin resistance, based on Matsuda index below the 50th percentile of women with normal glucose tolerance (NGT), during a 75 g OGTT at 24-28 weeks' gestation. GDM was diagnosed in 12.4% (n = 228) of all participants based on the 2013 WHO criteria. RESULTS: Compared with women with NGT (1113 [61.4%] of the total cohort) and insulin-sensitive women with GDM (39 [17.1%] women with GDM), women with GDM and high insulin resistance (189 [82.9%] women with GDM) had a significantly higher BMI, systolic BP, fasting plasma glucose (FPG), fasting total cholesterol, LDL-cholesterol and triacylglycerol levels in early pregnancy. Compared with women with NGT, insulin-sensitive women with GDM had a significantly lower BMI but similar BP, FPG and fasting lipid levels in early pregnancy. Compared with women with NGT, women with GDM and high insulin resistance had higher rates of preterm delivery (8.5% vs 4.7%, p = 0.030), labour induction (42.7% vs 28.1%, p < 0.001), Caesarean section (total Caesarean sections: 28.7% vs 19.4%, p = 0.004; emergency Caesarean sections: 16.0% vs 9.7%, p = 0.010), neonatal hypoglycaemia (15.4% vs 3.5%, p < 0.001) and neonatal intensive care unit admissions (16.0% vs 8.9%, p = 0.003). In multivariable logistic regression analyses using different models to adjust for demographics, BMI, FPG, HbA1c, lipid levels and gestational weight gain in early pregnancy, preterm delivery (OR 2.41 [95% CI 1.08, 5.38]) and neonatal hypoglycaemia (OR 4.86 [95% CI 2.04, 11.53]) remained significantly higher in women with GDM and high insulin resistance compared with women with NGT. Insulin-sensitive women with GDM had similar pregnancy outcomes as women with NGT. The need for insulin treatment during pregnancy and the rate of glucose intolerance in the early postpartum period were not significantly different among the GDM subtypes. CONCLUSIONS/INTERPRETATION: GDM with high insulin resistance represents a more adverse metabolic profile with a greater risk of adverse pregnancy outcomes.

Risk factor screening for gestational diabetes mellitus based on the 2013 WHO criteria

Objective: Since many European countries use risk factor screening for gestational diabetes mellitus (GDM), we aimed to determine the performance of selective screening for GDM based on the 2013 WHO criteria. Design and Methods: Overall, 1811 women received universal screening with a 75 g oral glucose tolerance test (OGTT) with GDM in 12.5% (n = 231) women based on the 2013 WHO criteria. We retrospectively applied different European selective screening guidelines to this cohort and evaluated the performance of different clinical risk factors to screen for GDM. Results: By retrospectively applying the English, Irish, French and Dutch guidelines for selective screening, respectively 28.5% (n = 526), 49.7% (n = 916), 48.5% (n = 894) and 50.7% (n = 935) had at least one risk factor, with GDM prevalence of respectively 6.5% (n = 120), 7.9% (n = 146), 8.0% (n = 147) and 8.4% (n = 154). Using maternal age ≥30 and/or BMI ≥25 for screening, positive rate was 69.9% (n = 1288), GDM prevalence 10.2% (n = 188), sensitivity 81.4% (CI: 75.8­86.2%) and specificity 31.8% (CI: 29.5­34.1%). Adding other clinical risk factors did not improve detection. GDM women without risk factors had more neonatal hypoglycemia (14.4 vs 4.0%, P = 0.001) and labor inductions (39.7 vs 25.9%, P = 0.020) than normal-glucose tolerant women, and less cesarean sections than GDM women with risk factors (13.8 vs 31.0%, P = 0.010). Conclusions: By applying selective screening by European guidelines, about 50% of women would need an OGTT with the lowest number of missed cases (33%) by the Dutch guidelines. Screening with age ≥30 years and/or BMI ≥25, reduced the number of missed cases to 18.6% but 70% would need an OGTT.

Prediction of Glucose Intolerance in Early Postpartum in Women with Gestational Diabetes Mellitus Based on the 2013 WHO Criteria.

Predictors for glucose intolerance postpartum were evaluated in women with gestational diabetes mellitus (GDM) based on the 2013 World Health Organization (WHO) criteria. 1841 women were tested for GDM in a prospective cohort study. A postpartum 75g oral glucose tolerance test (OGTT) was performed in women with GDM at 14 ± 4.1 weeks. Of all 231 mothers with GDM, 83.1% (192) had a postpartum OGTT of which 18.2% (35) had glucose intolerance. Women with glucose intolerance were more often of Asian origin [15.1% vs. 3.7%, OR 4.64 (1.26⁻17.12)], had more often a recurrent history of GDM [41.7% vs. 26.7%, OR 3.68 (1.37⁻9.87)], higher fasting glycaemia (FPG) [5.1 (4.5⁻5.3) vs. 4.6 (4.3⁻5.1) mmol/L, OR 1.05 (1.01⁻1.09)], higher HbA1c [33 (31⁻36) vs. 32 (30⁻33) mmol/mol, OR 4.89 (1.61⁻14.82)], and higher triglycerides [2.2 (1.9⁻2.8) vs. 2.0 (1.6⁻2.5) mmol/L, OR 1.00 (1.00⁻1.01)]. Sensitivity of glucose challenge test (GCT) ≥7.2 mmol/l for glucose intolerance postpartum was 80% (63.1%⁻91.6%). The area under the curve to predict glucose intolerance was 0.76 (0.65⁻0.87) for FPG, 0.54 (0.43⁻0.65) for HbA1c and 0.75 (0.64⁻0.86) for both combined. In conclusion, nearly one-fifth of women with GDM have glucose intolerance postpartum. A GCT ≥7.2 mmol/L identifies a high risk population for glucose intolerance postpartum.

A Modified Two-Step Screening Strategy for Gestational Diabetes Mellitus Based on the 2013 WHO Criteria by Combining the Glucose Challenge Test and Clinical Risk Factors.

This study determines if a modified two-step screening strategy with a glucose challenge test (GCT) ≥ 7.2 mmol/L and clinical risk factors improves the diagnostic accuracy for gestational diabetes mellitus (GDM), based on 2013 WHO criteria, while limiting the number of oral glucose tolerance tests (OGTT). This was a prospective multicentric cohort study with 1811 participants receiving both GCT and 75 g OGTT in pregnancy. Participants and health care providers were blinded for GCT. Characteristics were analyzed across four glucose tolerance groups: abnormal (≥7.2 mmol/L), GCT GDM (n = 165), normal GCT GDM (n = 63), abnormal GCT normal glucose tolerant (NGT) (n = 472); normal GCT NGT (n = 1113). Compared to normal GCT NGT women, normal GCT GDM women had increased rates of obesity (23.8% vs. 10.5%, p < 0.001), ethnic minority background (19.3% vs. 8.2%, p < 0.001) and a history of GDM (13.8% vs. 4.6%, p = 0.03). By combined screening of GCT ≥ 7.2 mmol/L with these risk factors, sensitivity increased to respectively, 74.1⁻78.1% using one risk factor, and to 82.9% using any of these risk factors with a specificity of 57.5%. By using a modified two-step screening strategy, the number of women needing both a GCT and OGTT would be reduced to 25.5%, and 52.6% of all OGTTs could be avoided, compared to a universal one-step approach.

Depression and Anxiety: Lack of Associations with an Inadequate Diet in a Sample of Pregnant Women with a History of Bariatric Surgery-a Multicenter Prospective Controlled Cohort Study.

BACKGROUND: Anxiety and depression levels are higher in obese compared to those in normal weight pregnant women. The aims of this study are to examine anxiety and depression in pregnancy following bariatric surgery and to compare with obese pregnant controls considering the dietary intake of polyunsaturated fatty acids (PUFA), folate, and vitamin B12. METHODS: Anxiety (State-Trait Anxiety Inventory) and depression (Edinburgh Postnatal Depression Scale) were examined in the first (T1) and third (T3) pregnancy trimester in 54 women with bariatric surgery and 25 obese. T1 and T3 dietary intake of PUFA, folate, and vitamin B12 intake was assessed using a 3-day food record. Mixed models with a compound symmetry covariance structure and regression models were applied. RESULTS: About half of the women with surgery had high state and trait anxiety scores (≥ 40), which did not significantly change during pregnancy. Every 10-kg postoperative weight loss was associated with an increase in T1 state and trait anxiety with respectively 2.7 and 2.3 points. A smoking woman had a 8.6-point higher state anxiety score than a non-smoking woman in T1. In T3, every additional hour of sleep was associated with a decrease in trait anxiety score with 1.59 points. Anxiety and depression scores were not associated with and could not be explained by inadequate PUFAs, folate, and vitamin B12 intakes. Anxiety scores were higher following surgery than those in untreated obesity at both time points. CONCLUSION: Pregnancy following bariatric surgery induces high levels of anxiety that are not associated with an inadequate maternal diet.

Comparison of subjective sleep and fatigue in breast- and bottle-feeding mothers.

OBJECTIVES: Artificial milk supplementation remains a popular practice in spite of the well documented and indisputable advantages of breast feeding for both mother and child. However, the association between maternal sleep, fatigue and feeding method is understudied and remains unclear. The aim of this study is to investigate whether perceived sleep and fatigue differ between breast- and bottle feeding post partum women. In addition, the relationship between subjective sleep characteristics and fatigue is examined. METHODS: Post partum women (four to 16 weeks) filled out a socio-demographic questionnaire, the Pittsburgh Sleep Quality Index (PSQI) and the Checklist Individual Strength (CIS). FINDINGS: Sixty-one within the past week exclusively breast- and 44 exclusively bottle-feeding mothers were included. The first group showed better subjective sleep quality, but lower habitual sleep efficiency as measured by the PSQI. Global PSQI, as well as subjective fatigue and global CIS, did not differ between the two groups. Significant positive correlations were found between global CIS and the number of night feeds and global PSQI. However, only global PSQI significantly predicted global CIS in relation to the number of night feeds. CONCLUSIONS: Within a general pattern of deteriorated sleep quality, breast-feeding women showed better subjective sleep quality, but lower habitual sleep efficiency, between four and fourteen weeks after childbirth. However, the PSQI component scores compensated for each other, resulting in absence of any difference in global PSQI sleep quality between the two groups. Global PSQI significantly predicted global CIS, resulting in an absence of any difference in post partum fatigue according to feeding method. IMPLICATIONS FOR PRACTICE: Midwives and nurses should, together with the parents, continue to focus on exploring ways to improve maternal sleep quality and to reduce postnatal fatigue.

The predictive value of quantitative fibronectin testing in combination with cervical length measurement in symptomatic women.

BACKGROUND: The combination of the qualitative fetal fibronectin test and cervical length measurement has a high negative predictive value for preterm birth within 7 days; however, positive prediction is poor. A new bedside quantitative fetal fibronectin test showed potential additional value over the conventional qualitative test, but there is limited evidence on the combination with cervical length measurement. OBJECTIVE: The purpose of this study was to compare quantitative fetal fibronectin and qualitative fetal fibronectin testing in the prediction of spontaneous preterm birth within 7 days in symptomatic women who undergo cervical length measurement. STUDY DESIGN: We performed a European multicenter cohort study in 10 perinatal centers in 5 countries. Women between 24 and 34 weeks of gestation with signs of active labor and intact membranes underwent quantitative fibronectin testing and cervical length measurement. We assessed the risk of preterm birth within 7 days in predefined strata based on fibronectin concentration and cervical length. RESULTS: Of 455 women who were included in the study, 48 women (11%) delivered within 7 days. A combination of cervical length and qualitative fibronectin resulted in the identification of 246 women who were at low risk: 164 women with a cervix between 15 and 30 mm and a negative fibronectin test (<50 ng/mL; preterm birth rate, 2%) and 82 women with a cervix at >30 mm (preterm birth rate, 2%). Use of quantitative fibronectin alone resulted in a predicted risk of preterm birth within 7 days that ranged from 2% in the group with the lowest fibronectin level (<10 ng/mL) to 38% in the group with the highest fibronectin level (>500 ng/mL), with similar accuracy as that of the combination of cervical length and qualitative fibronectin. Combining cervical length and quantitative fibronectin resulted in the identification of an additional 19 women at low risk (preterm birth rate, 5%), using a threshold of 10 ng/mL in women with a cervix at <15 mm, and 6 women at high risk (preterm birth rate, 33%) using a threshold of >500 ng/mL in women with a cervix at >30 mm. CONCLUSION: In women with threatened preterm birth, quantitative fibronectin testing alone performs equal to the combination of cervical length and qualitative fibronectin. Possibly, the combination of quantitative fibronectin testing and cervical length increases this predictive capacity. Cost-effectiveness analysis and the availability of these tests in a local setting should determine the final choice.

AURORA: bariatric surgery registration in women of reproductive age - a multicenter prospective cohort study.

BACKGROUND: The expansion of the obesity epidemic is accompanied with an increase in bariatric procedures, in particular in women of reproductive age. The weight loss induced by the surgery is believed to reverse the negative impact of overweight and obesity on female reproduction, however, research is limited to in particular retrospective cohort studies and a growing number of small case-series and case-(control) studies. METHODS/DESIGN: AURORA is a multicenter prospective cohort study. The main objective is to collect long-term data on reproductive outcomes before and after bariatric surgery and in a subsequent pregnancy. Women aged 18-45 years are invited to participate at 4 possible inclusion moments: 1) before surgery, 2) after surgery, 3) before 15 weeks of pregnancy and 4) in the immediate postpartum period (day 3-4). Depending on the time of inclusion, data are collected before surgery (T1), 3 weeks and 3, 6, 12 or x months after surgery (T2-T5) and during the first, second and third trimester of pregnancy (T6-T8), at delivery (T9) and 6 weeks and 6 months after delivery (T10-T11). Online questionnaires are send on the different measuring moments. Data are collected on contraception, menstrual cycle, sexuality, intention of becoming pregnant, diet, physical activity, lifestyle, psycho-social characteristics and dietary supplement intake. Fasting blood samples determine levels of vitamin A, D, E, K, B-1, B-12 and folate, albumin, total protein, coagulation parameters, magnesium, calcium, zinc and glucose. Participants are weighted every measuring moment. Fetal ultrasounds and pregnancy course and complications are reported every trimester of pregnancy. Breastfeeding is recorded and breast milk composition in the postpartum period is studied. DISCUSSION: AURORA is a multicenter prospective cohort study extensively monitoring women before undergoing bariatric surgery until a subsequent pregnancy and postpartum period. TRIAL REGISTRATION: Retrospectively registered (July 2015 - NCT02515214 ).

Creatine kinase as an indicator for hysterectomy in postpartum endomyometritis due to group A streptococci: a hypothesis illustrated by a case report.

BACKGROUND: Puerperal group A streptococcus (GAS) infection, once the leading cause of postpartum sepsis, has been increasing again since the 1980s. Streptococcal toxic shock syndrome (STSS) is a serious complication characterized by rapidly spreading GAS infection, shock, and multiple organ failure. Immediate recognition and implementation of therapy is crucial for survival. Making informed decisions regarding surgical debridement, namely hysterectomy, based on clinical indicators is difficult for practitioners. OBJECTIVES: This article discusses the potential role of creatine kinase in the decision-making process for treatment of STSS, particularly with regard to hysterectomy. MATERIAL AND METHODS: A case report is presented. The literature was searched using the key words 'group A streptococcus', 'postpartum hysterectomy', 'creatine kinase', 'endomyometritis', and 'streptococcal toxic shock syndrome' in PubMed and the UptoDate database. Relevant articles published between 1991 and 2011 were evaluated. CONCLUSION: Decisions regarding hysterectomy in STSS management are difficult. A rise in CK levels in the serum may indicate involvement of the myometrium and may be an important parameter in the difficult decision of hysterectomy when treating STSS.
