Despite its impressive fund of source knowledge, these data are potentially biased and unreliable and may not reflect current stances. In addition, ChatGPT does not list sources for its information, and its current capability to answer clinical questions correctly is not well understood. This study aimed to assess answers given by ChatGPT in response to a spectrum of questions about obstetrics and gynecology including systems-level questions, ethical questions, and treatment-related decision making. A total of 14 questions were asked. The first question asked why US preterm birth rates are so high. The second question asked for a list of the most important interventions physicians can do to monitor, prevent, and treat premature births. The third question asked whether vaginal progesterone was effective and safe for preventing preterm birth in women with a short cervix in the midtrimester, and the fourth question asked the same question but in women with a history of preterm birth and no short cervix. The fifth question asked why maternal mortality rates in the United States are so high. The sixth question asked for a list of what obstetricians can do to prevent preeclampsia. The seventh question asked about the safety of hospital births when compared with planned home births in the United States. The eighth question asked whether it is ethically acceptable for an obstetrician to provide emergency cesarean delivery without a woman's informed consent to save the fetus or the mother. The ninth question asked how obstetricians should screen for domestic abuse and intimate partner violence in pregnancy. The 10th question asked if women should freeze their eggs and at what age. The 11th question asked about the risks and benefits of menopause hormone replacement therapy. The 12th question asked how abortion bans in the United States affect women's health and lives. The 13th question asked whether complex hyperplasia atypia surgery should be performed only by a gynecologist-oncologist. The final question asked whether we should continue using the term “pregnant woman” versus alternative including “pregnant person.” Overall, ChatGPT provided nuanced and informed answers to question on virtually any topic in obstetrics and gynecology, but occasionally revealed an apparent lack of insight into the questions being asked.

International professional guidelines recommend heparin anticoagulation for antiphospholipid syndrome, an acquired thrombophilia responsible for approximately 15% of recurrent miscarriage, but not for other inherited thrombophilias due to an absence of evidence. Many clinicians prescribe heparin to women with recurrent miscarriage and inherited thrombophilia despite the professional recommendations. This international, open-label, randomized controlled trial aimed to compare the effect of low-molecular weight heparin (LMWH) and standard pregnancy surveillance on livebirth rates in women with recurrent miscarriage and inherited thrombophilia. Women aged 18–42 years with recurrent miscarriages who were attempting to conceive or less than 7 weeks pregnant and had an inherited thrombophilia were recruited across 40 hospitals in 5 countries. Women were randomly assigned to LMWH or no LMWH in a 1:1 ratio. Women randomized to LMWH self-administered it once a day subcutaneously, beginning as soon as possible after a positive pregnancy test and before 7 weeks of gestation and continuing throughout pregnancy. The primary study outcome was livebirth after 24 weeks of gestation. Livebirth was compared across randomized treatment groups using an χ 2 test with continuity correction, then a sensitivity analysis with logistic regression to adjust for stratification factors. A total of 326 women were randomized between August 2012 and January 2021. Of these, 164 were randomized to LMWH plus standard care and 162 to standard care alone. In the standard care group, 30 patients ultimately received LMWH for thromboprophylaxis per professional treatment guidelines. The mean age of participants was 33 years, and the median number of miscarriages before randomization was 3 (interquartile range, 2–4), with two thirds of patients having a history of 3 or more miscarriages. The most common thrombophilia diagnoses were heterozygosity for factor V Leiden, prothrombin G20210A mutation, and protein S deficiency. The livebirth rate was 72% (116/162) in the LMWH group, and 71% (112/158) in the standard care group, and no statistical significant was detected between the groups even after adjustment (odds ratio, 1.08; 95% confidence interval, 0.65–1.78; P = 0.77). No differences in adverse pregnancy outcomes or complications were observed between the groups. Easy bruising was reported by 45% (73) women in the LMWH group and 10% (16) in the standard care group. This randomized controlled trial demonstrates that although LMWH is safe in women with recurrent pregnancy loss and inherited thrombophilia, it does not result in an increased live birth rate compared with standard pregnancy surveillance.","PeriodicalId":19409,"journal":{"name":"Obstetrical & Gynecological Survey","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136010006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Low-dose aspirin treatment has been studied in the context of preeclampsia prevention, but there have been conflicting results among different populations. Some reasons for this are heterogeneous treatment regimens including timing, dosage, and even target outcomes. Among populations where there are limited data on the effect of low-dose aspirin on preeclampsia are women with chronic hypertension. This study is a systematic review and meta-analysis designed to analyze the use of low-dose aspirin during pregnancy and to assess whether the treatment reduces the risk of superimposed preeclampsia in women with chronic hypertension. It also aimed to secondarily assess related outcomes such as small for gestational age (SGA), preterm birth, and perinatal mortality. Systematic searches and assessment isolated 9 articles for final analysis. Six of these were randomized controlled trials, and 3 were retrospective cohort studies. Four studies focused on populations of only women with chronic hypertension, and the others included women with several different risk factors for preeclampsia. The retrospective studies and one of the randomized controlled trials compared aspirin treatment with no treatment, and the others compared with a placebo group; all studies used a dose of aspirin between 60 and 150 mg daily. No studies were excluded from the analysis based on risk of bias, as none were determined to be “critical” or “high” risk, although risk of bias was determined to be a contributing factor to low-quality data. Final analysis included a pooled sample size of 1078 individuals with chronic hypertension on low-dose aspirin, compared with 1072 women with chronic hypertension in control groups. This analysis did not find a decreased odds of superimposed preeclampsia in either randomized controlled trials (odds ratio [OR], 0.83; 95% confidence interval [CI], 0.55–1.25) or observational studies (OR, 1.21; 95% CI, 0.78–1.87). No significant differences were found with aspirin treatment, possibly due to risk of bias, heterogeneity, and imprecision. These findings held true when analyzed based on the timing of aspirin treatment induction (before or after 20 weeks' gestation), still finding no difference in the rate of superimposed preeclampsia. Low-dose aspirin treatment did reduce the odds of preterm birth according to a pooled analysis of 2 randomized controlled trials (OR, 0.62; 95% CI, 0.45–0.89). However, neither SGA nor perinatal mortality was shown to be significantly different in a pooled analysis of the studies that reported this outcome. Although these findings did not show statistical significance in reduction of preeclampsia in women with chronic hypertension due to aspirin treatment, the data are suggestive of benefit; many individuals in each study were lost to follow-up, and thus, the results of the analysis are different than they m","PeriodicalId":19409,"journal":{"name":"Obstetrical & Gynecological Survey","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136010150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several approaches have been investigated for screening, prevention, and treatment; one drug that shows activity against CMV is valacyclovir, and prenatal administration of this drug has been investigated in the context of preventing fetal disorders due to CMV. Although studies and clinical trials have been done regarding the safety and effectiveness of valacyclovir, clinical attitudes regarding universal CMV screening and prenatal valacyclovir treatment have yet to change. This article is a systematic review and meta-analysis of the safety and effectiveness of prenatal valacyclovir in CMV-infected pregnancies. Inclusion criteria included pregnancies with CMV infection diagnosed through serology, with a primary outcome of incidence of congenital CMV confirmed by polymerase chain reaction from amniocentesis. Secondary outcomes included symptomatic infection (rash, jaundice, microcephaly, seizures, hepatosplenomegaly, hearing loss, visual loss, retinitis, and central nervous system anomalies), asymptomatic infection, perinatal death, pregnancy termination, fetal anomaly, or severe symptoms. Adverse events related to the administration of valacyclovir were also recorded. Because relatively few studies were available for inclusion, the authors were unable to assess publication bias, but other risk of bias was assessed using standard tools. Final analysis included 8 studies and 620 pregnant women with CMV in 2 randomized controlled trials and 6 observational studies. One randomized controlled trial focused on valacyclovir treatment for CMV infection acquired in early pregnancy, and the other assessed valacyclovir treatment between 34 and 38 weeks' gestation to reduce risk of CMV within 1 year of delivery. The latter of the 2 studies was not included in pooled data synthesis because of inclusion criteria differences. Three studies focused on valacyclovir treatment for confirmed maternal CMV infection; pooled data analysis showed that valacyclovir-treated pregnancies had lower risk of congenital CMV (odds ratio [OR], 0.37; 95% confidence interval [CI], 0.21–0.64; P < 0.001). When contracted in the first trimester, risk of vertical transmission was lower in those who were treated with valacyclovir (OR, 0.34; 95% CI, 0.15–0.74; P = 0.001); however, there was no effect observed in those with CMV in the periconceptual period. Analysis additionally showed that prenatal valacyclovir treatment was more likely to result in asymptomatic children (OR, 2.98; 95% CI, 1.18–7.55; P = 0.021), but no other significant perinatal differences were observed. These results show that treatment of CMV with prenatal valacyclovir reduces the risk of congenital CMV and its associated complications.

In cases where viral infection does occur, these can cause mild to severe complications in both mother and fetus; many viruses that result in such complications are DNA viruses. Current diagnosis technology for DNA viruses relies largely on polymerase chain reaction (PCR), which is very sensitive but generally targeted at a specific virus and so tends to not be very comprehensive. In addition, this testing is normally performed only on those who are at high risk or expressing symptoms. To more fully understand the effect and prevalence of DNA viruses in pregnancy, this study used noninvasive prenatal testing (NIPT) that captures cell-free DNA (cfDNA) to examine the DNA virome in pregnant women between 2017 and 2020. Data included deidentified NIPT results for 108,349 individuals, and DNA sequences were used to screen for 224 DNA viruses. Viruses that were genetically similar were differentiated based on taxonomy through a meticulous decision tree to avoid generalized errors in categorizing them. The most commonly detected virus was parvovirus B19, occurring in approximately 1 in 3000 cfDNA reads. High viral loads were also observed for hepatitis B, Bocaparvovirus , papillomavirus, adenovirus, adeno-associated virus, Epstein-Barr virus (EBV)/herpesvirus 4, cytomegalovirus (CMV), herpesvirus 6, and torque teno virus. A cross-examination of demographic and pregnancy factors revealed many associations, most of which remained significant after adjustments for multiple comparisons. Available characteristics included maternal age, body mass index (BMI), gestational age, fetal fraction, and the number of sequenced reads with the presence of viral DNA in the samples. Detection of viral DNA was associated with lower BMI, along with a lower concentration of cfDNA and a higher fetal fraction. When individual viruses were analyzed, CMV had the most significant relationship with gestational age and maternal age. Results additionally showed that low fetal fraction was associated with lower detection of viral DNA for specific viruses. These results show that it is feasible to detect viral DNA in NIPT samples. If viral DNA can be detected, there is potential to diagnose infection and to possibly prevent complications due to the virus. Current clinical practice does not use NIPT as a diagnostic tool for viral infection, but there is potential for this in the future. Further research should focus on clinical utility, sensitivity, specificity, and accuracy, as well as the relationship of viral DNA with low fetal fraction.","PeriodicalId":19409,"journal":{"name":"Obstetrical & Gynecological Survey","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135963383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This was a multicenter, double-blind, randomized controlled trial including 31 hospitals participating in the Maternal-Fetal Medicine Units Network of the Eunice Kennedy Shriver National Institute of Child Health and Human Development. Eligibility criteria included scheduled or unscheduled cesarean delivery of a singleton or twin gestation. Exclusion criteria included maternal age younger than 18 years, blood transfusion before randomization, plan for transfusion after randomization, contraindications to TXA, patient decision not to use blood products, or administration of antifibrolytic agents or uterotonic agents other than oxytocin. The primary outcome was maternal death or blood transfusion before hospital discharge or 7 days after delivery, whichever came first. Secondary outcomes included intraoperative blood loss of more than 1 L and treatments or interventions in response to bleeding or related complications within 7 days of delivery, as well as infectious complications within 6 weeks of delivery. Final analyses included 11,000 patients, with 5529 in the TXA group and 5471 in the placebo group. Baseline characteristics were not significantly different between groups, and no center-dependent differences were observed. The primary outcome was observed in 3.6% of patients in the TXA group and 4.3% of patients in the placebo group (adjusted relative risk, 0.89; P = 0.19). Intraoperative blood loss of more than 1 L was recorded in 7.3% and 8.0% in the tranexamic and placebo groups, respectively (relative risk, 0.90; 95% CI, 0.79–1.05). Treatments and interventions in response to bleeding occurred in 16.1% of individuals in the TXA group and 18.0% of those in the placebo group (relative risk, 0.90; 95% CI, 0.82–0.97). Infectious complications were reported in 3.2% and 2.5% in the TXA and placebo groups, respectively (relative risk, 1.28; 95% CI, 1.02–1.61). Sensitivity analysis showed similar results to initial analysis, and no significant differences were seen between groups in major safety outcomes. This analysis indicates that the administration of TXA during cesarean delivery did not lower the risk of maternal death or blood transfusion. These results are in direct contradiction to previous research showing that TXA is effective at reducing these outcomes. This trial was stronger than any previous studies in sample size and careful randomization ensuring equal representation of scheduled and unscheduled c","PeriodicalId":19409,"journal":{"name":"Obstetrical & Gynecological Survey","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135963380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bozio, Susan Hariri","doi":"10.1097/01.ogx.0000993680.79685.68","DOIUrl":"https://doi.org/10.1097/01.ogx.0000993680.79685.68","url":null,"abstract":"ABSTRACT Many illnesses can become especially serious when contracted within the first year of life; pertussis remains quite deadly despite recent medical advances in disease prevention. Current guidance on vaccination in the United States includes 3 doses of the DTaP (diphtheria, tetanus toxoid, and acellular pertussis) vaccine beginning at 2 months of age, but this regimen leaves infants younger than that very vulnerable to illness. Research has shown both that vaccinating mothers with tetanus toxoid reduces tetanus, diphtheria, and pertussis (Tdap) between 27 and 36 weeks of gestation significantly reduces instances of pertussis in infants younger than 2 months, and that maternal vaccination rates have risen in the last few years. However, research is lacking in analyzing the relationship between vaccination rates in pregnant mothers and the burden of pertussis in infants in the United States. This study was designed to assess data from 2000 to 2019 and examine the association of Tdap vaccination during pregnancy with trends in infant pertussis. This analysis included data obtained from the National Notifiable Diseases Surveillance System between 2000 and 2019. This included a total of 57,460 cases of pertussis in infants younger than 1 year and a total of 19,322 cases in infants younger than 2 months. The rate of pertussis incidence for infants younger than 2 months in the time period before the implementation of prenatal Tdap was calculated to be 165.3 per 100,000 individuals, with no significant trend observed annually ( P = 0.28). After the implementation of routine maternal Tdap, incidence decreased to 80.9 per 100,000 infants between 2017 and 2019. Accounting for both time periods, the mean annual incidence was calculated as 121.8 per 100,000 infants younger than 2 months. Annual incidence also showed a significant decreasing trend in the period after implementation of maternal Tdap vaccination (slope: −14.53 per 100,000 infants per year; P = 0.001). The change in trends before and after this implementation was also significant ( P = 0.01). In a slightly older age group of 6 to 12 months of age, mean annual incidence of pertussis was 19.7 per 100,000 infants. In the time period before implementation of maternal Tdap, incidence among infants aged 6 to 12 months was consistently 4 to 12 times less than infants younger than 2 months and did not significantly change after the implementation of the maternal vaccine. Comparing the 2 age groups, there was no significant change in the difference in incidence between infants younger than 2 months and those between 6 and 12 months in the period before the maternal vaccine, and after its implementation, there was a significant decrease in the incidence difference between the 2 groups ( P < 0.001). These results suggest an association between the maternal Tdap vaccination and trends of pertussis incidence in infants younger than 2 months. This also indicates a possible reduction in disease burden at","PeriodicalId":19409,"journal":{"name":"Obstetrical & Gynecological Survey","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136009752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
