Abstract
BACKGROUND Gestational diabetes mellitus (GDM) is a complication of pregnancy strongly associated with an increased risk of structural fetal abnormalities. As the fetal heart grows quickly during the late-term pregnancy period, it is important to understand fetal heart growth before birth. This study explored how GDM affects fetal heart growth by evaluating basic echocardiography indicators during late pregnancy. METHODS This prospective, longitudinal study included 63 GDM patients (GDM group) and 67 healthy pregnant women (control group). All subjects underwent fetal echocardiography scans at gestational weeks 28-32, 32-36, and 36-40. Twelve echocardiographic indicators were assessed at each observation and analyzed by using a mixed model. RESULTS The left atrial diameter (LA) and left ventricular end-diastolic diameter (LV) similarly increased from the first to the third observation. The right ventricular end-diastolic diameter (RV) was significantly different between the groups, and a group × time interaction was detected. The tricuspid annular peak systolic velocity (s') increased more rapidly in the GDM than the control group during the first to second observations, and the group × time interaction was significant. The increase in the tricuspid annular plane systolic excursion (TAPSE) of the GDM group was "slow-fast", while that of the control group was "fast-slow", during three observations. After adjusting covariates, the group difference and interaction effect of TAPSE and RV remained significant. CONCLUSIONS The differences in fetal right heart indicators between the GDM and control groups suggest that GDM may affect the structure and functional growth of the fetal right heart during late-term pregnancy.

Application of ultrasound-based radiomics technology in fetal-lung-texture analysis in pregnancies complicated by gestational diabetes and/or pre-eclampsia. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2021; 57:804-812. [PMID: 32250510 DOI: 10.1002/uog.22037] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Revised: 03/06/2020] [Accepted: 03/27/2020] [Indexed: 06/11/2023]
Abstract
OBJECTIVES To analyze and compare, using ultrasound-based radiomics technology, fetal-lung texture in pregnancies affected by gestational diabetes mellitus (GDM) and/or pre-eclampsia (PE) and in normal pregnancies, overall and at different gestational ages. METHODS In this retrospective study, 430 high-throughput features per fetal-lung image were extracted from 548 fetal-lung ultrasound images (obtained at the level of the four-chamber view of the heart) in 548 pregnant women who delivered between July 2018 and August 2019 at the Obstetrics and Gynecology Hospital of Fudan University. Images had been obtained during ultrasound examinations between 28 and 41 weeks of gestation. The data were divided randomly into training set (80% of fetal-lung images) and independent test set (20% of images), and 20% of the images in the training set were then selected as the validation set. A standard machine-learning model based on ultrasound-based radiomics technology was created using features of fetal-lung texture extracted from the images, and a regression model was used to evaluate the relationship between lung-texture features, GDM and/or PE and gestational age. RESULTS Of the 548 pregnancies included, 108 were affected by GDM alone, 71 by PE alone and 25 by both GDM and PE, and 344 were normal. The overall performance of the GDM and PE prediction model was superior to that of the gestational-age prediction model, with an area under the receiver-operating-characteristics curve of 0.95-0.99, sensitivity of 78.8-97.1% in the validation set and 74.5-91.3% in the independent test set, specificity of 79.8-94.3% in the validation set and 75.7-88.4% in the independent test set and accuracy of 81.0-95.3% in the validation set and 80.6-86.4% in the independent test set. CONCLUSIONS Using ultrasound-based radiomics technology, fetal lungs from pregnancies grouped according to whether they were affected by GDM and/or PE could be distinguished from each other and from fetal lungs of normal pregnancies, and lungs from pregnancies at different gestational ages could be distinguished. These findings support further research to explore the use of this non-invasive technology to predict neonatal respiratory complications in women with PE, GDM or their combination. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
OBJECTIVE To compare outcomes among neonates delivered after documentation of fetal lung maturity before 39 weeks and those delivered at 39 or 40 weeks. METHODS This was a retrospective cohort study of women with singleton pregnancy delivered at 36 0/7 to 38 6/7 weeks after positive fetal lung maturity testing (based on amniotic fluid lecithin to sphingomyelin ratio) or at 39 0/7 to 40 6/7 weeks (without maturity testing) at our center from 1999 to 2008. Women with fetuses with major congenital anomalies, cord prolapse, nonreassuring antepartum testing, placental abruption, or oligohydramnios were excluded. A primary composite neonatal outcome included death, adverse respiratory outcomes, hypoglycemia, treated hyperbilirubinemia, generalized seizures, necrotizing enterocolitis, hypoxic ischemic encephalopathy, periventricular leukomalacia, and suspected or proven sepsis. RESULTS There were 459 neonates delivered at 36 to 38 weeks and 13,339 delivered at 39 to 40 weeks; mean birth weight was 3,107±548 g and 3,362±439 g, respectively. The risk of the composite adverse neonatal outcome was 6.1% for the 36- to 38-week group compared with 2.5% for the 39- to 40-week group (relative risk 2.4; confidence interval [CI] 1.7-3.5). After multivariable adjustment, early delivery remained significantly associated with an increased risk of the composite outcome (adjusted odds ratio [OR]1.7; CI 1.1-2.6) as well as several individual outcomes, including respiratory distress syndrome (adjusted OR 7.6; CI 2.2-26.6), treated hyperbilirubinemia (adjusted OR 11.2; CI 3.6-34), and hypoglycemia (adjusted OR 5.8; CI 2.4-14.3). CONCLUSION Neonates delivered at 36 to 38 weeks after confirmed fetal lung maturity are at higher risk of adverse outcomes than those delivered at 39 to 40 weeks.

Abstract
Gestational diabetes mellitus (GDM) is commonly defined as glucose intolerance first recognized during pregnancy. Diagnostic criteria for GDM have changed over the decades, and several definitions are currently used; recent recommendations may increase the prevalence of GDM to as high as one of five pregnancies. Perinatal complications associated with GDM include hypertensive disorders, preterm delivery, shoulder dystocia, stillbirths, clinical neonatal hypoglycemia, hyperbilirubinemia, and cesarean deliveries. Postpartum complications include obesity and impaired glucose tolerance in the offspring and diabetes and cardiovascular disease in the mothers. Management strategies increasingly emphasize optimal management of fetal growth and weight. Monitoring of glucose, fetal stress, and fetal weight through ultrasound combined with maternal weight management, medical nutritional therapy, physical activity, and pharmacotherapy can decrease comorbidities associated with GDM. Consensus is lacking on ideal glucose targets, degree of caloric restriction and content, algorithms for pharmacotherapy, and in particular, the use of oral medications and insulin analogs in lieu of human insulin. Postpartum glucose screening and initiation of healthy lifestyle behaviors, including exercise, adequate fruit and vegetable intake, breastfeeding, and contraception, are encouraged to decrease rates of future glucose intolerance in mothers and offspring.

Abstract
Type 1 diabetes complicates around 1 in 200 to 300 pregnancies in the United Kingdom. Historically maternal type 1 diabetes carried very high risks for mother and child. Introduction of insulin led to an immediate, marked decline in the previously very high rates of maternal mortality; in contrast an improvement in perinatal outcomes occurred more slowly but was nevertheless dramatic. This is strikingly demonstrated by the temporal decline in perinatal mortality in offspring of mothers with type 1 diabetes which was virtually universal before use of insulin in the 1920's, likely remained in excess of 20% even in the 1960's and fell to under 4% by the 1990's. The reasons for this more gradual improvement in perinatal outcomes cannot be defined with precision but will have been influenced by improved glycaemic management with use of intensive, multiple dose insulin treatment and home glucose monitoring; improvements in obstetric and neonatal management, and better management of complications of diabetes before and during pregnancy. In 1989 the St Vincent declaration proposed that pregnancy outcomes in women with type 1 diabetes should approximate those of the non-diabetic population. While the long term improvements in fetal outcomes have been dramatic, contemporary surveys confirm a persistent doubling or more of rates of congenital anomaly and a three to four fold increase in perinatal mortality in the UK and other European countries which will require further clinical innovation to overcome.

Abstract
OBJECTIVE The purpose of this study was to give a detailed description of recovery benchmarks that occur in patients whose therapy after partial meniscectomy knee arthroscopy consists of a home program of exercise. These benchmarks can be used as a basis for clinicians to compare improvements to individual patients who receive supervised care. DESIGN Thirty-nine patients (five females, mean age = 41) who underwent an uncomplicated arthroscopic partial meniscectomy were included. Test sessions occurred at 5 and 50 days after surgery. Outcome measures included: 1) Hughston Clinic knee self-assessment questionnaire; 2) EQ-5D Tariff for assessment of quality of life; 3) number of days taken to return to work after surgery; 4) knee passive range of motion; and 5) knee swelling assessed by evaluation of knee circumference. Stepwise regression analysis was used to evaluate factors that might have influenced the amount of pre- to posttest change in the outcome measures (the benchmarks) during the first 7 wks after surgery. The factors used in this analysis were: 1) age, 2) body mass index, 3) period from injury to surgery, and 4) the baseline value of the variable to be examined (except for return to work, where we used a score estimating the challenge to the knee offered by work). RESULTS None of the factors considered (age, body mass index, period from injury to surgery, stressfulness of the work on the knee) affected the number of days taken to return to work. Baseline scores affected change in all the other outcomes, and knee girth change was also affected by body mass index. Regression equations are presented where suitable for the benchmarks presented. CONCLUSIONS Quick recovery occurs in these patients when only a home exercise program is given. This paper highlights the utility of using historical control group data instead of test-retest analysis of measurement error in evaluating patients whose recovery with a home exercise program is rapid. Of the variables analyzed in this study, quality of life and knee self-assessment changes offer the most useful benchmarks for evaluating treatment effectiveness.
