Utilizing ChatGPT to Facilitate Referrals for Fetal Echocardiography.

INTRODUCTION: OpenAI's GPT-4 (artificial intelligence [AI]) is being studied for its use as a medical decision support tool. This research examines its accuracy in refining referrals for fetal echocardiography (FE) to improve early detection and outcomes related to congenital heart defects (CHDs). METHODS: Past FE data referred to our institution were evaluated separately by pediatric cardiologist, gynecologist (human experts [experts]), and AI, according to established guidelines. We compared experts and AI's agreement on referral necessity, with experts addressing discrepancies. RESULTS: Total of 59 FE cases were addressed retrospectively. Cardiologist, gynecologist, and AI recommended performing FE in 47.5%, 49.2%, and 59.0% of cases, respectively. Comparing AI recommendations to experts indicated agreement of around 80.0% with both experts (p < 0.001). Notably, AI suggested more echocardiographies for minor CHD (64.7%) compared to experts (47.1%), and for major CHD, experts recommended performing FE in all cases (100%) while AI recommended in majority of cases (90.9%). Discrepancies between AI and experts are detailed and reviewed. CONCLUSIONS: The evaluation found moderate agreement between AI and experts. Contextual misunderstandings and lack of specialized medical knowledge limit AI, necessitating clinical guideline guidance. Despite shortcomings, AI's referrals comprised 65% of minor CHD cases versus experts 47%, suggesting its potential as a cautious decision aid for clinicians.

[EFFECT OF ETHNICITY ON BACTERIAL RESISTANCE AND OBSTETRICAL OUTCOMES AMONG PREGNANT WOMEN ADMITTED TO MATERNAL-FETAL MEDICINE UNIT WITH THE DIAGNOSIS OF PYELONEPHRITIS DURING 2017-2020].

INTRODUCTION: Antibiotic resistance is a worldwide concern. No study has ever examined the correlation between ethnicity and antibiotic resistance. We examined those parameters among hospitalized pregnant patients diagnosed with pyelonephritis. AIMS: Should ethnic origin play a role in optimizing antibiotic therapy? To better comprehend, we have chosen a cohort of hospitalized pregnant patients with a pyelonephritis diagnosis. METHODS: A total of 105 cases of patients hospitalized in the Shamir Medical Center between the years 2017-2020 were analysed. Feto-maternal outcomes and antibiotic resistance in relation to ethnicity were plotted statistically using chi-square tests (Arab, 40%; North Africa, 13%; Europe-Ashkenaz,10%; Ethiopia/Iran/Kavkaz/Iraq/other, 3%; Turkey/Uzbekistan/Yemen 2%). RESULTS: Ethnic groups included Arab (40%), others referred as "None-Arab". The antibiotic resistance panel revealed differences comparing the two largest groups (Arab% VS non-Arab%), whereas there was no correlation between any ethnic group and obstetrics parameter. Arab women were more resistant to ciprofloxacin (33% vs 7%, P= 0.026) and less sensitive to imipenem (60% vs 90.9%, P= 0.03); less sensitive to ceftriaxone and cefuroxime. CONCLUSIONS: There was a correlation between ethnic origin of pregnant patients diagnosed with pyelonephritis and antibiotic resistance. We hope ethnicity, might, in some cases, assist physicians choosing the optimal therapy.

Third trimester re-screening for gestational diabetes in morbidly obese women despite earlier negative test can reveal risks for obstetrical complications.

AIM: We investigated associations of maternal obesity with late gestational diabetes mellitus (GDM) diagnosis (>34 weeks) in women with previous normal glucose screening, and associations of late GDM with obstetrical outcomes. METHODS: This retrospective cohort study assessed obstetrical and neonatal outcomes of 238 women with normal (24-28 week) glucose screening results, who underwent late repeat oral glucose tolerance tests (OGTT) (>34 weeks) due to a suspected LGA fetus (54.6%) or polyhydramnios (45.4%). A sub-analysis was performed of outcomes of women with late versus mid-trimester GDM. RESULTS: The GDM rate in repeat OGTT screening was 22.2% for the total sample, and 33% among women with morbid obesity. Among women with late GDM versus without late GDM, rates were higher for macrosomia, large-for-gestational-age fetus induction of labor, neonatal hypoglycemia, jaundice, and the need for phototherapy. Among women with late GDM, a higher pregestational BMI was associated with adverse maternal and perinatal outcomes. Higher risks for macrosomia and CS due to macrosomia were demonstrated in women with late vs. mid-trimester GDM. CONCLUSION: Late screening in pregnancy may reveal GDM among women with previous normal glucose screening, particularly among those with late third trimester BMI ≥ 35 kg/m2 , GDM in a previous pregnancy or fasting glucose >95 mg/dl. Women diagnosed with GDM at >34 weeks following normal glucose screening at 24-28 weeks are at higher risk for adverse perinatal outcomes. For women with morbid obesity, or suspected macrosomia or polyhydramnios in the late third trimester, and normal glucose screening in the second trimester, retesting should be considered.

Clinical implications of the 100-g oral glucose tolerance test in the third trimester.

PURPOSE: The clinical implications of gestational diabetes mellitus (GDM) diagnosed in the third trimester are not well established and controversy continues regarding the performance of diagnostic tests beyond 28-week gestation. This study aimed to evaluate the incidence of abnormal third trimester oral glucose tolerance test (OGTT) results in women at high risk and to compare the obstetric and neonatal outcomes with those of women with normal OGTT results. METHODS: The study included 372 women who completed late (>29 weeks) 100-g OGTT due to suspected fetal macrosomia, polyhydramnios or a personal risk factor for GDM, diagnosed according to the Carpenter & Coustan criteria. Women with only one abnormal OGTT value were diagnosed with GDM by abnormal glucose follow-up and analyzed separately. Obstetric and neonatal outcomes were compared between the GDM and the non-GDM groups. RESULTS: GDM was diagnosed in 85/372 (22%) women, including 35 (59.3%) women with one abnormal OGTT value who were later diagnosed with GDM. Of 200 women who had a normal 1-h 50-g glucose challenge test at 24-28 weeks, late GDM was diagnosed in 33 (16.5%). Seventy-six (89.5%) of those with GDM were treated by dietary therapy and 9 (10.5%) by pharmacological therapy. Among women with GDM, large-for-gestational-age fetuses, labor induction and elective cesarean section were more prevalent than for those without GDM. Significant differences were not found between the groups in macrosomia and neonatal outcomes. CONCLUSIONS: The performance of OGTT in women with risk factors during the third trimester should be considered following further prospective trials.

[THE FALL AND RISE OF PROGESTERONE PREPARATIONS IN THE PREVENTION OF PRETERM LABOR].

INTRODUCTION: Preterm labor involves about 7.4% of live births in Israel and constitutes over 85% of morbidity and mortality in newborns. Risk factors for preterm labor include a history of preterm delivery shortening of the uterine cervix, cervical procedures, uterine malformations, polyhydramnios, intrauterine growth restriction, preeclampsia, multiple gestations, and more. Progesterone is an essential hormone in the process of fertilization and is involved in the menstrual cycle, implantation and preservation of pregnancy. Due to its various functions in the prevention of preterm labor, the use of progesterone as a preventive treatment has been extensively studied since the second half of the last century and tested in various forms of administration, mainly intramuscular injection and vaginal root. For years, women with a history of preterm labor were treated with intramuscular progesterone once a week between 16 to 36 weeks' gestation or until birth. Recently, vaginal progesterone treatment was initiated in women with cervical length > 25 mm measured by ultrasound between 18-24 weeks gestation. Studies have shown that progesterone treatment reduces the incidence of preterm labor given in the proper indication. This update overview examines progesterone treatment for the prevention of preterm labor.

[MATERNAL SERUM ANGIOGENIC FACTORS AS AN AIDING TOOL FOR SCREENING WOMEN WITH SUSPECTED PREECLAMPSIA NEAR DELIVERY - INITIAL DATA AND AN ESTIMATED COST-BENEFIT].

INTRODUCTION: Preeclampsia (PE) is a major pregnancy complication, posing considerable morbidity and mortality. The maternal serum angiogenic factors - PlGF and sFlt-1, and their ratio appear to be promising markers to predict PE. Aims: To assess whether the evaluation of PlGF and sFlt-1 adds to the clinical workup of women with suspected PE, and to estimate the cost/benefit. METHODS: We prospectively enrolled pregnant women with suspected PE who were admitted to the Maternal-Fetal Medicine Unit (MFM) at Shamir Medical Center. Pregnancy and delivery records were collected from their computerized electronic medical records. PlGF<150pg/ml and sFlt-1/PlGF>38 measured prospectively were used to predict PE. RESULTS: Of 105 women included, 28 were in the control group with unrelated complications and none developed PE. Among 66 women with suspected PE, 27(41%) developed the syndrome, with a positive predictive value (PPV) of 90.3% for PlGF<150 pg/ml and 88.9% for sFlt-1/PlGFabove 38. Out of 11 women with suspected intrauterine growth restriction (IUGR), six developed the syndrome, and among them, the negative predictive value (NPV) was ~ 90%. CONCLUSIONS: Angiogenic factors are reliable in predicting PE near delivery. Of 8355 annual deliveries, 584 were admitted for suspected PE. The annual test cost was NIS 66,576 (NIS 140 per single test). Cost-saving was NIS 2.18 million, the ratio of cost saved vs. test cost was 32.7. DISCUSSION: The angiogenic factors are efficient and cost-saving in PE prediction near delivery. A larger study is necessary to determine the inclusion of angiogenic factors in the workup for suspected PE.

Impact of the COVID-19 Pandemic on Excess Perinatal Mortality and Morbidity in Israel.

OBJECTIVE: The 2020 COVID-19 pandemic has been associated with excess mortality and morbidity in adults and teenagers over 14 years of age, but there is still limited evidence on the direct and indirect impact of the pandemic on pregnancy. We aimed to evaluate the effect of the first wave of the COVID-19 pandemic on obstetrical emergency attendance in a low-risk population and the corresponding perinatal outcomes. STUDY DESIGN: This is a single center retrospective cohort study of all singleton births between February 21 and April 30. Prenatal emergency labor ward admission numbers and obstetric outcomes during the peak of the first COVID-19 pandemic of 2020 in Israel were compared with the combined corresponding periods for the years 2017 to 2019. RESULTS: During the 2020 COVID-19 pandemic, the mean number of prenatal emergency labor ward admissions was lower, both by daily count and per woman, in comparison to the combined matching periods in 2017, 2018, and 2019 (48.6 ± 12.2 vs. 57.8 ± 14.4, p < 0.0001 and 1.74 ± 1.1 vs. 1.92 ± 1.2, p < 0.0001, respectively). A significantly (p = 0.0370) higher rate of stillbirth was noted in the study group (0.4%) compared with the control group (0.1%). All study group patients were negative for COVID-19. Gestational age at delivery, rates of premature delivery at <28, 34, and 37 weeks, pregnancy complications, postdate delivery at >40 and 41 weeks, mode of delivery, and numbers of emergency cesarean deliveries were similar in both groups. There was no difference in the intrapartum fetal death rate between the groups. CONCLUSION: The COVID-19 pandemic stay-at-home policy combined with patient fear of contracting the disease in hospital could explain the associated higher rate of stillbirth. This collateral perinatal damage follows a decreased in prenatal emergency labor ward admissions during the first wave of COVID-19 in Israel. KEY POINTS: · Less obstetrical ER attendance is observed during the pandemic.. · There is a parallel increase in stillbirth rate.. · Stillbirth cases tested negative for COVID-19.. · Lockdown and pandemic panic are possible causes..

Impact of the Israeli Ministry of Health Cytomegalovirus Guidelines on the Local Pregnancy Outcome.

OBJECTIVE: In 2011, the Israeli Ministry of Health (MOH) published standard guidelines for the follow-up of pregnant women infected by CMV, recommending that amniocentesis be performed in cases of maternal serum viral seroconversion or abnormal sonographic findings suggestive of CMV, in order to prove fetal infection before electing for pregnancy termination. METHODS: A retrospective cohort study was performed, describing 448 pregnant women from 2006 to 2017. We collected data from all women that elected to continue their pregnancies after seroconversion and also of those who chose to undergo pregnancy termination. Subsequently, a telephone survey was then conducted to record outcomes of the newborns of women with CMV seroconversion during pregnancy. RESULTS: 325 (73%) women chose to continue their pregnancy, while 123 (27%) opted for termination of pregnancy. We found that pregnancy termination due to CMV infection was reduced by 7%, from 72 cases (32%) to 51 cases (25%) after the implementation of the MOH guidelines in 2011. In addition, 182/305 (60%) of women responded to our telephone questionnaire regarding newborn outcomes. Of these women, 45/305 (14%) reported complications, and no correlation was found between the prenatal findings and postnatal outcome among those who have responded to our survey. CONCLUSION: Implementation of the new MOH guidelines has reduced the rate of pregnancy termination, without increasing the rate of neonatal complications in Israel with a similar outcome of complication rate as reported in the literature.

[USING MATERNAL SERUM PLACENTAL GROWTH FACTOR (PLGF) FOR RULING OUT PREECLAMPSIA NEAR DELIVERY: PRELIMINARY RESULTS AND ECONOMIC IMPLICATIONS IN ISRAEL].

INTRODUCTION: Preeclampsia (PE) is a major obstetric complication affecting 3-5% of pregnancies and a major contributor to fetal and maternal morbidity and mortality. The level of placental growth factor (PLGF) >150pg/ml in the third trimester was reported to predict PE occurrence within the next 14 days. AIMS: We have conducted a preliminary study among pregnant Israeli women in order to evaluate whether maternal serum PLGF test at admission with suspected PE could rule-out the risk for developing PE. METHODS: We prospectively enrolled pregnant women who were admitted to the high-risk pregnancy department at Shamir Medical Center with suspected PE. The women signed an informed consent form and blood samples were drawn, separated into serum, and taken for PLGF immuno-diagnostic test. All women with suspected PE were managed according to local protocol. The medical staff was blinded regarding PLGF results. All patients' computerized medical records, including developing of PE within 14 days and patients' computerized medical records were collected and a telephone interview was held to verify whether post charging events occurred. RESULTS: Of the 29 women who were enrolled in the study, the group with PLGF<150 pg/ml included 19 women, who had mean PLGF=44.7pg/ml [(95%CI: 6.5-95.3], of which 14 developed PE (positive predictive value 73.7%). There were ten women in the PLGF>150pg/ml group, with mean PLGF=528.7 pg/ml [(95% CI:168-1300, P<0.001)] of which one developed PE (negative predictive value 90%). The sensitivity for ruling out PE by PLGF>150pg/ml was 93%, and the specificity=64.3. CONCLUSIONS: Incorporating blood testing of PLGF into the evaluation triage of pregnant women in Israel who admitted to the delivery clinic with suspected development of PE has generated high efficacy and negative predictive value (NPV) as was previously published Our findings are in accordance with results reported elsewhere but need validation in Israel with larger studies. DISCUSSION: Assuming that at least 7% of ~184,450 (2018) live births in Israel are admitted to the high risk departments for evaluating suspected PE, implementing a PLGF test has a cost-benefit ratio of ~1/8.28 with a cost of NIS 2.52M for test performance of all women attending the delivery clinic with suspected PE over saving NIS 21.37M on unnecessary hospital days.

Effect of pre-gestational weight and gestational weight gain in women with gestational diabetes controlled with medication on pregnancy outcomes - is recommended weight gain too liberal?

This is a retrospective cohort study of women with GDM treated with glucose-lowering agents that were followed and gave birth between 2005 and 2015 in the Assaf Harofeh medical center, Israel. Classification and regression tree method identified four groups according to adverse outcomes, consisted of 74 women with pre-gestational BMI below 25, 98 women with BMI 25-31, 90 women 31-39 and 18 women above 39. Respectively, median GWG was 12 kg (8-16), 11 kg (8-15), 7.5 kg (3.75-11) and 5 kg (-1.5 to 11.5) (p < .001). The risk for composite adverse outcomes was higher in the groups of BMI 25-31 (73.5%) and 31-39 (83.3%) in comparison to BMI <25 (51.4%) and 39 < (55.6%), p < .001. In women with pre-gestational BMI of <25, GWG of more than the median resulted in odds ratio of 2.75 (1.07-7.08, p = .036) for adverse pregnancy outcomes compared with participants who gained less than the median. Maternal obesity is related to adverse pregnancy outcomes. Women with GDM with normal pre-gestational BMI who gained weight according to IOM recommendations still experienced adverse outcomes.

Thyroid Disease in Pregnancy: A Clinical Survey among Endocrinologists, Gynecologists, and Obstetricians in Israel.

OBJECTIVES: To study the current practices in the management of subclinical hypothyroidism (SCH) and thyroid nodules during pregnancy of obstetricians/gynecologists (OB/GYNs) and endocrinologists in Israel. METHODS: An electronic questionnaire was sent by email to all members of the Israeli Endocrine Society and the Israel Society of Obstetrics and Gynecology. Questionnaires included demographic data and clinical scenarios with questions regarding the screening and management of pregnant women with SCH, hypothyroxinemia, and a palpable thyroid nodule. The questionnaire for OB/GYNs was slightly modified. RESULTS: We received 90 responses from endocrinologists and 42 responses from OB/GYNs. Among endocrinologists, 39% would repeat a thyroid-stimulating hormone (TSH) test of 2.9 mU/L with normal free thyroxine and treat with thyroxine if the second result was above 2.5 mU/L. Among OB/GYNs, 73% would manage a woman with SCH at the beginning of her pregnancy by themselves and only 22% would start thyroxine after a first TSH result above 2.5 mU/L. Concerning screening, 57% endocrinologists and 71% OB/GYNs recommended screening for thyroid dysfunction in every woman at the beginning of her pregnancy. Among endocrinologists, 54% would order an ultrasound for a palpable thyroid nodule and perform a fine needle aspiration only for suspicious lesions. CONCLUSIONS: The medical approach to thyroid disease in pregnant women remains a matter of controversy. Our results support the need for larger and prospective clinical studies.

[First year experience using arabin cervical pessary with intravaginal micronized progesterone for the prevention of preterm birth in patients with mid-trimester short cervix].

BACKGROUND: Arabin cervical pessary is a silicone ring pessary for the prevention of preterm birth (PTB] for pregnant women at risk with second trimester short uterine cervix. Progesterone supplementation has been found to prevent PTB. OBJECTIVE: To review our first year of experience using Arabin cervical pessary with intravaginal micronized progesterone in the prevention PTB. METHODS: The study included patients (pt) with singleton and twin pregnancies at 16-30 weeks with uterine cervical length < or = 25 mm treated with Arabin cervical pessary and intravaginal progesterone over one year from September 2011 to September 2012. Progesterone treatment was continued until 34 weeks and pessary was extracted at 36 weeks or in cases of preterm labor, bleeding or other medical indications. RESULTS: The study group included 43 patients, 31 (72.1%) singleton and 12 (27.9%) twins. The average week at admission was 25+2 weeks [w] [SD +/- 3.05], and the average cervical length at admission was 13.5 mm (SD +/- 5.0). A total of 11 patients had previous PTB; in 2 patients the pessary was placed after cerclage failure. The average week of delivery was 35 + 5 weeks SD +/- 3.2 (singleton 36 + w SD +/- 2.6, twins 33 + 4 SD +/- 4.1, p = 0.05); the average time between pessary insertion to delivery 72.1 days SD +/- 26.2 (singleton 76.3 SD +/- 22.9 twins 60.2 SD +/- 28.9 p = 0.02), in 23 patients (53.5%) the pessary was extracted at > or = 36 + 6w, 5 patients 111.6%) delivered < or = 32w (2 singleton, 3 twins, p = 0.08) and 18 patients (41.8%) reported increased vaginal discharge. CONCLUSION: The use of cervical pessary in conjunction with intravaginal progesterone is safe and feasible. Patients with twin pregnancies had a significantly higher rate of preterm birth compared to singleton pregnancies. Further research is needed to assess device efficacy.

The effect of hereditary versus acquired thrombophilia on triple test Down's syndrome screening.

OBJECTIVE: To compare the profile of mid gestation triple test serum markers between a cohort of women with history of pregnancy complications with hereditary versus acquired thrombophilia. All were treated with low molecular weight heparin (LMWH) prior to 12 weeks' gestation. METHODS: A retrospective analysis of second trimester maternal serum screening results for Down syndrome was performed comparing women with inherited versus acquired thrombophilia, all treated with LMWH. The test results were calculated from the combination of triple serum markers and maternal age, and expressed as a multiple of the gestation normal medians (MoM). Results in the study groups were compared with MoM values calculated from our local population (controls). RESULTS: The median human chorionic gonadotropin (hCG) level was higher only in the acquired thrombophilia group (N = 47) as compared with the control group (1.3 vs. 0.99 MoM, P = 0.005), and not different between the hereditary thrombophilia group (N = 60) (1.1 MoM) and the control group. Alpha-fetoprotein and unconjugated estriol MoMs did not differ between women with inherited (0.95, 0.97), acquired thrombophilia (0.99, 0.90), and controls (1.01, 0.98), respectively. CONCLUSION: In the interpretation of second trimester maternal serum screening, consideration should be given to the higher hCG maternal serum levels that may occur in women with acquired thrombophilia, even those treated early in pregnancy with LMWH. The higher hCG serum levels may signal the possibility of placental dysfunction, rather than fetal aneuploidy.

Azathioprine and 6-mercaptopurine-induced intrahepatic cholestasis of pregnancy: Case report and review of the literature.

OBJECTIVE: Azathioprine, a prodrug of 6-mercaptopurine (6-MP), is used in the treatment of inflammatory bowel disease and may be continued during pregnancy. Acute cholestatic liver injury has been reported to occur with azathioprine. We aimed to examine azathioprine related cholestasis effect on pregnancy complications and outcome. CASE REPORT: We present a unique case of 6-MP-induced severe intrahepatic cholestasis of pregnancy (ICP) that required meticulous combined therapy including plasma exchange. The symptoms resolved following 6-MP withdrawal. A literature review revealed 11 pregnancies complicated by early-induced severe ICP among women treated with azathioprine or 6-MP. CONCLUSION: We recommend weekly bile acid level tests for pregnant women treated with azathioprine or 6-MP, beginning early in the second trimester of pregnancy, and the prompt discontinuation of treatment upon establishment of an ICP diagnosis.

Does low molecular weight heparin influence the triple test result in pregnant women with thrombophilia?

BACKGROUND: The triple test serum markers for Down's syndrome screening may be altered because of various conditions other than chromosomal trisomies. OBJECTIVES: To assess the profile of mid-trimester triple test serum markers in a cohort of women treated with low molecular weight heparin (LMWH) for thrombophilia since the first trimester. METHODS: Women with inherited or acquired thrombophilia treated with LMWH prior to 12 weeks gestation were followed between October 2006 and September 2009 at our obstetric outpatient clinic. The second-trimester screening test for Down syndrome was calculated from the combination of triple serum markers and maternal age, and expressed as a multiple of the gestation-specific normal median (MoM). Reference MoM values were calculated from the local population. Data on pregnancy outcome were obtained from patient records. RESULTS: The median human chorionic gonadotropin (hCG) level of women with inherited thrombophilia was 0.87 MoM, compared to 0.99 MoM in controls (P = 0.038) and compared to 1.355 MoM in women with acquired thrombophilia (P = 0.034). In contrast, alpha-fetoprotein MoMs did not differ significantly between women with inherited and women with acquired thrombophilia (0.88 vs. 0.99 MoM, P = 0.403). CONCLUSIONS: The triple test serum markers may be altered in thrombophilia patients treated with LMWH. Clinicians should consider offering these patients the first-trimester nuchal translucency test and other sonographic markers that are probably unaffected by the underlying maternal disease and/or treatment modality.

Insulin treatment of patients with gestational diabetes: does dosage play a role?

BACKGROUND AND OBJECTIVE: In nonpregnant patients high insulin requirements are associated with hypoglycemia and weight gain but not with improvement in glucose control. The effect of insulin requirement on maternal and neonatal outcomes in gestational diabetes mellitus (GDM) is yet unknown. METHODS: We conducted a retrospective cohort study of maternal and neonatal outcomes of pregnancy according to insulin requirements in women with GDM who were followed and delivered at the Yitzhak Shamir Medical Center between 2006 and 2016. The daily insulin dose in units per body weight was divided into quartiles and analyses were performed to compare the lowest, highest, and two middle quartiles. The primary outcome was a composite of any of the following: cesarean-section (CS), preeclampsia, macrosomia and large for gestational age (LGA) birth weight, neonatal intensive care unit admission, need for phototherapy, and neonatal hypoglycemia. RESULTS: Women were divided according to their insulin requirements as follows: 79 (24.8%) women who needed <0.13 IU/kg/day of insulin (insulin-sensitive group), 160 (50%) women who needed 0.14-0.42 IU/kg/day of insulin (comparison-group), and the rest who needed >0.43 IU/kg/day of insulin (insulin resistant group). There were no differences in the composite outcome between the groups (64.6, 61.3, and 69.6% for the insulin sensitive-, comparison- and resistant- groups, respectively, p = .44). Women in the insulin-resistant group had higher fasting glucose levels in the first trimester (91, 98 and 102 mg/dL for women in the insulin sensitive-, comparison- and insulin-resistant groups, respectively; p = .01). Women in the insulin-sensitive group had significantly better glycemic control (fasting glucose levels ≤90 mg/dL and 1-hour and 2-hour postprandial glucose levels ≤140 mg/dL and ≤120 mg/dL for more than 80% of measurements) than those in the insulin-resistant group (70.3 versus 29.9%; p < .001). The rate of CS was significantly higher in the insulin-resistant group (42.3 versus 24.1%; p = .03), but the rate of LGA birth weight was surprisingly higher in the insulin-sensitive group (29.5 versus 16.7%, p = .04). After controlling for confounders, women in the insulin-sensitive group had a decreased risk for CS in relation to the comparison group (OR = 0.46, 95%CI 0.23-0.9, p = .025). CONCLUSION: We found no association between insulin requirements and adverse composite outcome in women with GDM. However, those with higher insulin requirements have poorer glucose control and higher rates of CS than those with lower insulin requirements. Larger studies are needed to inquire short- and long-term outcomes of insulin requirements on fetal and maternal outcomes.

The risk of small and large for gestational age newborns in women with gestational diabetes according to pre-gestational body mass index and weight gain.

AIM: To explore the effects of pregestational body mass index (BMI) and gestational weight gain (GWG) on maternal and neonatal outcomes of women with gestational diabetes mellitus (GDM). METHODS: We conducted retrospective cohort analyses of outcomes among women with GDM who delivered at Shamir Medical Center, Israel (2017-2018). RESULTS: We included 673 women with GDM in our analysis, 217 (32.24%) with appropriate GWG (aGWG), 247 (36.7%) with excessive GWG (eGWG), and 209 (31%) with insufficient GWG (iGWG). Cesarean section (CS) was less prevalent among women with iGWG (19.6%), compared with women with eGWG (31.2%) and aGWG (31.1%) (p = .008). Small for gestational weight (SGA) newborns were more prevalent in women with iGWG 9.1%, compared with 2% and 0.9% for women with eGWG and aGWG, respectively (p<.001). Large for gestational age (LGA) newborns were significantly more prevalent in women with eGWG 17.4% compared with 4.8% and 9.7% in patients with iGWG and aGWG women, respectively (p<.001). SGA and LGA newborns were more prevalent in women with iGWG and e-GWG across all pre-gestational BMI groups >18.5 kg/m2. CONCLUSIONS: A complex interplay exists between pregestational weight, GWG, and GDM and pregnancy outcomes, specifically SGA and LGA newborns. A strict follow-up considering the pregestational BMI, GWG, blood glucose levels, treatment modality, and fetal abdominal circumference could assist in managing the complex interplay of patients with GDM for better neonatal outcomes.

Postpartum retained products of conception: Retrospective analysis of the association with third stage of labor placental complications.

OBJECTIVE: To compare the prevalence of postpartum retained products of conception (RPOC) among parturients with a history of third stage of labor placental complications and parturients without those complications. STUDY DESIGN: All women operated for postpartum RPOC following vaginal delivery by hysteroscopy or suction curettage between January 2013 and December 2017 were included in the study. Their medical records were reviewed for the occurrence of third stage of labor placental complications (including early postpartum hemorrhage treated with uterotonics, manual separation of the placenta, and revision of the uterine cavity for removal of cotyledons). RESULTS: The study cohort included 172 women operated for postpartum RPOC following vaginal delivery by operative hysteroscopy (143 cases, 83.1%) or by suction curettage (29 cases, 16.9%). Third stage of labor placental complications were reported in 65 (37.8%) cases, while 107 (62.2%) women had an uncomplicated third stage of labor. When considering all vaginal deliveries in our institution during the study period, the risk for RPOC was significantly higher among parturients with third stage of labor placental complications compared to those with an uneventful third stage of labor (3.7% versus 0.3%, p < 0.001, Odds ratio = 12.5, 95% confidence interval 9.0-17.3). CONCLUSION: Postpartum RPOC following vaginal delivery were more common in parturients with third stage of labor placental complications. However, the majority of postpartum RPOC cases were diagnosed in women reported to have an uncomplicated third stage of labor. Thus, focused postpartum ultrasound follow-up of women considered at risk for RPOC will not identify all cases.

Splenic artery aneurysms during pregnancy: An obstetric nightmare.

OBJECTIVE: In this study we report our experience in the management of Splenic Artery Aneurysm (SAA), diagnosed during pregnancy. STUDY DESIGN: The current manuscript describes three different events, treated in out our department, involving SAAs diagnosed during pregnancy. Each case presents an unusual course and a unique clinical challenge. RESULTS: The first case is of a 25 week's gestation twin pregnancy with ruptured SAA ending in maternal and fetal death. Another case of SAA rupture presented at 27 week's gestation with consequent emergency cesarean section and splenectomy. In the last case, two SAAs were incidentally diagnosed at 25 weeks' singleton gestation. The patient was managed conservatively and delivered by an elective cesarean section at 34 weeks followed by postpartum angiographic embolization of the aneurysms. CONCLUSIONS: Health care providers and especially obstetricians should be aware of the diagnosis of ruptured SAA in a pregnant woman with abdominal discomfort and hemodynamic deterioration. In addition, once an asymptomatic pregnant patient is diagnosed with a SAA, conservative surveillance may be allowed.
