Postnatal catch-up growth in term newborns with altered fetal weight patterns. The GROWIN study.

BACKGROUND: Small for gestational age (SGA) perform a postnatal catch-up growth to recover their genetic trajectory. We studied the postnatal catch-up growth pattern of fetuses born with an appropriate-for-gestational-age (AGA) weight but with fetal growth deceleration (FGD) to explore whether they catch up. METHODS: Nine hundred and sixty-six newborns at Villalba University General Hospital (HUGV), were followed from 34 to 37 weeks to birth. Z-scores, adjusted for sex and age, of weight, length, and BMI at 3, 6, 9, and 12 months were calculated. We define catch-up as an increase in z-score greater than 0.67 SD in the growth curves. RESULTS: AGA FGD had lower mean weight and length than AGA non-FGD at all time points; BMI was lower until 3 months. AGA FGD had a lower weight, length, and BMI z-score (until 9, 6 months, and at birth, respectively) than AGA non-FGD. AGA FGD newborns had a significantly increased likelihood of weight catch-up at 3 months (OR 1.79; 95% CI: 1.16, 2.78; p = 0.009) and BMI in all investigated periods (OR 1.90; 95% CI 1.30, 2.78; p < 0.001 at 3 months), compared to AGA non-FGD newborns. CONCLUSIONS: AGA FGD newborns perform catch-up growth, especially in weight and BMI, in the first year of life, compared to AGA non-FGD. IMPACT: Appropriate-for-gestational-age (AGA) newborns with fetal growth deceleration (FGD), between the third trimester of pregnancy and delivery, present a lower weight and height, during the first year of life, compared to AGA non-FGD. Appropriate-for-gestational-age (AGA) newborns with fetal growth deceleration (FGD), between the third trimester of pregnancy and delivery, present a higher likelihood of weight catch-up in the first 3 months of life and of BMI in the first year compared to AGA non-FGD. AGA FGD experienced early weight and BMI catch-up, especially in the first 3 months of life, like SGA. This finding should be considered in the future follow-up.

Female sexual function before and during the severe acute respiratory syndrome coronavirus-2 pandemic: a systematic review and Meta-analysis of longitudinal studies.

PurposeTo compare the female sexual function before and during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic using the Female Sexual Function Index (FSFI).MethodsRelevant studies were retrieved by online databases and manual searching reporting FSFI scores before and during the SARS-CoV-2 pandemic. The methodological quality of reviewed articles was evaluated using the Newcastle-Ottawa Scale, and heterogeneity with the I2 statistic. The standardized mean differences (SMDs) with their 95% confidence intervals (CIs) were calculated by random-effect meta-analyses.ResultsFour studies met the inclusion criteria reporting 1002 sexually active non-pregnant women comparing results of the 19-item FSFI. The meta-analysis of the overall FSFI score showed an SMD (95% CI) of -1.16 (-1.97 to -0.35), comparing the pandemic with the pre-pandemic scores. In addition, SMD scores for the FSFI domains were also significantly lower during the pandemic for arousal -0.80 (-1.13 to -0.48), orgasm -0.66 (-1.07 to -0.25), satisfaction -0.59 (-0.97 to -0.22), and pain -0.35 (-0.54 to -0.16), whereas there were not significant differences for desire and lubrication domains. There was a low risk of bias and the sensitivity analysis suggests that results are robust.ConclusionThe available studies showed a lower overall FSFI score during the pandemic, suggesting an increased risk of female sexual dysfunction compared to prepandemic results. Also, there were increased risks of sexual arousal, orgasm, satisfaction, and pain disorders. However, there were no alterations in the desire and the lubrication domains. Limitations are related to the heterogeneity populations, and pandemic confounding and aggravating factors.

Systematic review and meta-analysis regarding maternal apelin in pregnant women with and without preeclampsia.

Aims: To investigate maternal circulating apelin levels in pregnancies with and without preeclampsia.Design and Method: Systematic review and meta-analysis of observational studies reporting circulating apelin in women who develop preeclampsia. We searched databases for appropriate studies published through December 2021, without language restriction. The quality of studies was evaluated using the Newcastle-Ottawa-Scale. Data were pooled as mean difference (MDs) or standardized MDs (SMDs) and 95% confidence interval (95% CI). A random-effects model enabled reporting of differences between groups, minimizing the effects of uncertainty associated with inter-study variability on the effects of different endpoints.Results: We identified a total of 122 studies, and ten of them reported circulating apelin in women with and without preeclampsia. Maternal apelin did not show a difference in preeclamptic compared to normotensive women (SMD: -0.38, 95%CI -0.91 to 0.15), although there was high heterogeneity between the included studies (I2 = 95%). Participants with preeclampsia had higher body mass index, lower gestational age at delivery, and birth weight. Preeclamptic pregnant women with higher BMI showed significantly lower apelin levels in the subgroup analysis. There was no significant apelin difference in the preeclampsia severity sub-analysis.Conclusion: There was no significant difference in apelin levels in pregnant women with and without preeclampsia.

Substance use, mental health and dual disorders on pregnancy: Results of prevalence and treatment rates in a developed country. / Salud mental, abuso de sustancias y trastornos duales en el embarazo: Tasas de prevalencia y tratamiento en un país desarrollado.

Smoking and substance use during pregnancy are major preventable causes of mortality and morbidity, having a bidirectional and deleterious relationship with the mental health of the mother and child. As part of the WOMAP (Woman Mental Health and Addictions on Pregnancy) initiative, our study aimed to describe the prevalence of co-occurring mental illness and substance use problems, diagnoses and severity of those considered at risk and rates of treatment.A screening of 2,014 pregnant women was done using the AC-OK scale and they were asked about their smoking habits and services use for mental health/substance abuse. Of these, 170 women were considered at risk of co-occurring mental illness and substance use problems (≥ 2 positive responses to the AC-OK-Mental Health subscale, ≥ 1 positive response to the AC-OK-Substance Abuse subscale and/or smoking more than once a month and no use of specialized services) and were assessed with a more extensive battery of measures (Patient Health Questionnaire [PHQ-9], General Anxiety Disorder [GAD-7], Posttraumatic stress disorder [PTSD] Checklist for DSM-5 [PCL-5], Alcohol Use Disorders Identification Test [AUDIT], Drug Abuse Screening Test [DAST] and Fagerström).In the last year, 614 women (30.5%) smoked tobacco (42.5% daily) and 9.8% were positive for both substance use and mental illness per the AC-OK. Only 11.1% of them received specific treatment in the previous three months while another 13.6% were scheduled to attend services in the following month. From the subsample assessed in depth, 62(36.5%) endorsed at least moderate depression, 35(20.6%) endorsed at least moderate anxiety, 32(18.8%) endorsed PTSD on the PCL, and 37 out of 88 alcohol users scored above the threshold in AUDIT (≥ 3). In conclusion, high prevalence and low treatment rates suggest that effective detection mechanisms should be integrated into usual care, allowing for early interventions.

El tabaquismo y el consumo de sustancias durante el embarazo son importantes causas prevenibles de morbimortalidad, teniendo una relación bidireccional y deletérea con la salud mental de la madre y el niño. Como parte de la iniciativa WOMAP (Woman Mental Health and Addictions on Pregnancy), se estudiaron 2.014 embarazadas buscando describir la prevalencia de trastornos mentales y por uso de sustancias concurrentes, las tasas de tratamiento y los diagnósticos y la gravedad. Las participantes fueron evaluadas con la escala AC-OK y se les preguntó sobre sus hábitos tabáquicos y uso de servicios de salud mental/sustancias. De las participantes, 170 mujeres resultaron positivas para un trastorno mental y por uso de sustancias concurrentes (≥ 2 positivos a la subescala AC-OK-Salud Mental, ≥ 1 positivos a la subescala AC-OK-Sustancias y/o fumar más de una vez al mes y no estar en tratamiento) y fueron evaluadas en profundidad mediante una batería de escalas (Patient Health Questionnaire [PHQ-9], General Anxiety Disorder [GAD-7], Post-traumatic stress disorder Checklist [PCL-5], Alcohol Use Disorders Identification Test [AUDIT], Drug Abuse Screening Test [DAST] y Fagerström).En el último año, 614 mujeres (30,5%) fumaron tabaco (42,5% diariamente) y el 9,8% fueron positivas para problemas por uso de sustancias y salud mental según la AC-OK. Solo el 11,1% había recibido tratamiento en los tres meses previos y solo un 13,6% tenía una cita en el siguiente mes. De las 170 pacientes evaluadas secundariamente, 62(36,5%) presentaron al menos depresión moderada, 35(20,6%) al menos ansiedad moderada, 32(18,8%) fueron positivas a la PCL-5, y 37 de las 88 que reconocieron uso de alcohol puntuaron por encima del umbral en AUDIT (≥ 3). En conclusión, la combinación de una prevalencia significativa junto con bajas tasas de tratamiento, remarcan la necesidad de mecanismos de detección efectivos en la atención habitual, permitiendo una intervención temprana.

Preeclampsia and gestational hypertension are associated to low maternal circulating kisspeptin levels: a systematic review and meta-analysis.

BACKGROUND: There are contradictory data concerning kisspeptin in gravids with preeclampsia and gestational hypertension (GH). OBJECTIVE: To conduct a meta-analysis of studies comparing maternal kisspeptin levels in gravids with and without preeclampsia or GH. MATERIAL AND METHODS: We searched PubMed, LILACS, and CNKI list of articles up to 20 August 2021, without language limitations, comparing circulating maternal kisspeptin levels, and maternal and neonatal outcomes in gravids with and without preeclampsia or GH. Meta-analyzed results are reported as standardized mean differences (SMD), and their 95% confidence interval (CI). RESULTS: Seven studies with a low-to-moderate risk of bias were eligible for meta-analysis. Gravids with preeclampsia or GH displayed significantly lower circulating kisspeptin levels (SMD, -0.68, 95% CI, -1.04 to -0.32), lower gestational ages at delivery (SMD, -2.22, 95% CI, -3.25 to -1.18), and birth weight (SMD, -2.16, 95% CI, -3.15 to -1.17), and significantly higher body mass indices (MD, 0.56, 95% CI, 0.24-0.88), systolic (SMD, 2.87, 95% CI, 2.22-3.53), and diastolic blood pressures (SMD, 2.57, 95% CI, 2.19-2.95). CONCLUSION: Gravids with preeclampsia or GH had lower kisspeptin levels as compared to normotensive controls.

Reduced Growth in Non-Small for Gestational Age Fetuses from 35 Weeks of Gestation to Birth and Perinatal Outcomes.

OBJECTIVE: This study aimed to assess reduced fetal growth between 35 weeks of gestation and birth in non-small for gestational age fetuses associated with adverse perinatal outcomes (APOs). MATERIAL AND METHOD: It is a retrospective cohort study of 9,164 non-small for gestational age fetuses estimated by ultrasound at 35 weeks. The difference between the birth weight percentile and the estimated percentile weight (EPW) at 35 weeks of gestation was calculated, and we studied the relationship of this difference with the appearance of APO. APOs were defined as cesarean or instrumental delivery rates for nonreassuring fetal status, 5-min Apgar score <7, arterial cord blood pH <7.10, and stillbirth. Fetuses that exhibited a percentile decrease between both moments were classified into 6 categories according to the amount of percentile decrease (0.01-10.0, 10.01-20.0, 20.01-30.0, 30.01-40.0, 40.01-50.0, and >50.0 percentiles). It was evaluated whether the appearance of APO was related to the amount of this percentile decrease. Relative risk (RR) was calculated in these subgroups to predict APOs in general and for each APO in particular. Receiver operating characteristic and area under curves (AUC) for the difference in the percentile was calculated, used as a continuous parameter in the entire study population. RESULTS: The median gestational age at delivery in uncomplicated pregnancies was 40.0 (39.1-40.7) and in pregnancies with APOs 40.3 (49.4-41.0), p < 0.001. The prevalence of APOs was greater in the group of fetuses with a decrease in percentile (7.6%) compared to those with increased percentile (4.8%) (p < 0.001). The RR was 1.63 (95% CI: 1.365-1.944, p < 0.001). Although the differences were significant in all decreased percentile groups, RRs were significantly higher when decreased growth values were >40 points (RR: 2.036, 95% CI: 1.581-2.623, p < 0.001). The estimated value of the AUC for percentile decrease was 0.58 (0.56-0.61, p < 0.001). CONCLUSION: Fetuses with a decrease in the EPW between the ultrasound at 35 weeks of gestation and birth have a higher risk of APOs, being double in fetuses with a decrease of >40 percentile points.

Prediction of Large for Gestational Age by Ultrasound at 35 Weeks and Impact of Ultrasound-Delivery Interval: Comparison of 6 Standards.

OBJECTIVE: The aim of the study was to assess the predictive ability of the ultrasound estimated percentile weight (EPW) at 35 weeks to predict large for gestational age (LGA) at term delivery according to 6 growth standards, including population, population-customized, and international references. The secondary objectives were to determine its predictive ability to detect adverse perinatal outcomes (APOs) and whether the ultrasound-delivery interval influences the detection rate of LGA newborns. METHODS: This was a retrospective cohort study of 9,585 singleton pregnancies. Maternal clinical characteristics, fetal ultrasound data obtained at 35 weeks, and pregnancy and perinatal outcomes were used to calculate EPWs to predict LGAs at delivery according to the customized and the non-customized (NC) Miguel Servet University Hospital (MSUH), the customized Figueras, the NC Fetal Medicine Foundation (FMF), the NC INTERGROWTH-21st, and the NC World Health Organization (WHO) standards. RESULTS: For a 10% false-positive rate, detection rates for total LGAs at delivery ranged from 31.2% with the WHO (area under the curve [AUC] 0.77; 95% confidence interval [CI], 0.76-0.79) to 56.5% with the FMF standard (AUC 0.85; 95% CI, 0.84-0.86). Detection rates and values of AUCs to predict LGAs by ultrasound-delivery interval (range 1-6 weeks) show higher detection rates as the interval decreases. APO detection rates ranged from 2.5% with the WHO to 12.6% with the Figueras standard. CONCLUSION: The predictive ability of ultrasound estimated fetal weight at 35 weeks to detect LGA infants is significantly greater for FMF and MSUH NC standards. In contrast, the APO detection rate is significantly greater for customized standards. The shorter ultrasound-delivery interval relates to better prediction rates.

Detection of Adverse Perinatal Outcomes at Term Delivery Using Ultrasound Estimated Percentile Weight at 35 Weeks of Gestation: Comparison of Five Fetal Growth Standards.

OBJECTIVE: To assess the predictive ability of the ultrasound estimated percentile weight (EPW) at 35 weeks of pregnancy to predict adverse perinatal outcomes (APOs) at term delivery according to 5 fetal growth standards, including population, population-customized, and international references. METHODS: This was a retrospective cohort study of 9,585 singleton pregnancies. Maternal clinical characteristics, fetal ultrasound data obtained at 35 weeks and pregnancy and perinatal outcomes were used to calculate EPWs to predict APOs according to: the customized and noncustomized (NC) Miguel Servet University Hospital (MSUH), the customized Figueras, the NC INTERGROWTH-21st, and the NC World Health Organization (WHO) international standards. APOs were defined as the occurrence of cesarean or instrumental delivery for nonreassuring fetal status, 5-min Apgar score < 7, arterial cord blood pH <7.10, or stillbirth. The predictive ability of EPW for APOs was analyzed using the area under the curve (AUC), and sensitivities were calculated for different false-positive rates (FPRs). RESULTS: For a 10% FPR, detection rates for total APOs ranged between 12.7% with the customized MSUH (AUC 0.52; 95% CI 0.50-0.55) and 14.4% with the NC MSUH standard (AUC 0.55; 95% CI 0.53-0.57) for EPW by ultrasound; and from 22.0% with the customized MSUH standard (AUC 0.60; 95% CI 0.58-0.63) to 27.8% with the NC WHO (AUC 0.65; 95% CI 0.63-0.68) for EPW at delivery. CONCLUSIONS: The predictive capacity of the EPW for APOS is limited and similar, by both ultrasound and at delivery, for the 5 growth standards, without significant differences between customized and NC standards.

[Sonographic fetal sex determination in the first trimester: study in 2314 pregnancies and literature review]. / Determinación ecográfica del sexo fetal en el primer trimestre de gestación: estudio en 2314 gestaciones y revisión bibliográfica.

OBJECTIVE: To evaluate the success rate and reliability of fetal sex determination in first trimester between 11-13+ 6 weeks and make a comparative study with other studies. MATERIAL AND METHODS: A cohort study was performed. 2314 first trimester pregnancy ultrasounds were examined. For fetal sex estimation, the method of a sagittal section and the relation between the angle formed by the genital tubercle and spinal column was used. RESULTS: Diagnosis of fetal sex was issued in 1986 cases with 90.1% success rate. In 328 cases (14.2%) no gender assignment was achieved. A directly proportional relationship between success rate in fetal sex diagnosis and crown-rump length (CRL) (p < 0.001) was described; with CRL over 65 mm, the prediction of fetal sex is above 95% and from 77 mm is close to 100%. With CRL < 51 mm, the success rate is less than 80% in both sexes. CONCLUSION: The simplest and best performing technique is the relation between the angle formed by the genital tubercle and spinal column. Success rate below 60 mm is less than 90% overall, so it would have to be wary of establishing the fetal sex, especially if it involves a decision as to avoid an invasive test.

[Massive gestational vulvar edema. A case report and review of literature]. / Edema vulvar masivo gestacional. Reporte de un caso y revisión de la bibliografía.

We report the case of a 22-year-old primiparous, admitted to our hospital with a 2-week history of vulvar edema that had evolved within 24 hours to the point of stopping urine flow and hindering ambulation. The only remarkable finding in relation with the edema was hypoalbuminemia for no apparent cause. The correction of hypoalbuminemia and the establishment of diuretic treatment, with the drainage of the edema allowed for a complete resolution of the edema.

[Prenatal diagnosis of right aortic arch. Types of presentation and postnatal evolution]. / Diagnóstico prenatal de arco aórtico derecho. Formas de presentación y evolución posnatal.

BACKGROUND: Right aortic arch is the most common abnormality of the aortic arch, excluding aberrant right subclavian artery. Its importance lies in its association with genetic syndromes, another important congenital heart defects, and that may cause clinical symptons from vascular rings. OBJECTIVE: Was to describe the prenatal clinical presentation, the correlation with postnatal findings and postnatal development of the fetus. METHODS: Observational retrospective analysis of 18 cases of right aortic arch diagnosed prenatally between the years 2005-2011. RESULTS: 5 pregnancies were interrupted because of ultrasound findings associated with poor prognosis. In 13 cases were term infants, with a good correlation between prenatal and postnatal findings, and the prognosis was excellent in cases in which the prenatal diagnosis of right aortic arch was isolated. CONCLUSIONS: In our experience, right aortic arch is a rare condition, but it can be associated with important congenital heart defects (heart disease or vascular rings) and/or other morphological anomalies in the fetus, in which case it should be ruled out chromosomal or genetic syndrome. If prenatally is considered an isolated finding, after careful ultrasound assessment by obstetricians and pediatric cardiologists, it is likely that evolution will be favorable postnatally.

[Split hand-foot: sonographic detection at 12 weeks]. / Ectrodactilia: detección ecográfica a las 12 semanas.

Split hand-foot malformation is a rare disorder inherited in an autosomal dominant pattern with variable expression. Inour case, it was detected early by ultrasound in the twelfth week of gestation. The sonographic findings were bilateral split hands and feet. No other alterations were observed in the rest of the systematic assessment of the foetal anatomy. The pathological findings were consistent with the sonographic diagnosis. Prenatal diagnosis by corionic villus sampling was performed and voluntary termination of gestation decided.

The utility of fetal heart rate deceleration's descending slope in searching for a non-National Institute of Child Health and Human Development parameter for the detection of fetal acidosis.

OBJECTIVE: To identify new parameters predicting fetal acidemia. METHODS: A retrospective case-control study in a cohort of deliveries from a tertiary referral hospital-based cohort deliveries in Zaragoza, Spain between 2018 and 2021 was performed. To predict fetal acidemia, the NICHD categorizations and non-NICHD parameters were analyzed in the electronic fetal monitoring (EFM). Those included total reperfusion time, total deceleration area and the slope of the descending limb of the fetal heart rate of the last deceleration curve. The accuracy of the parameters was evaluated using the specificity for (80%, 85%, 90%, 95%) sensitivity and the area under the receiver operating characteristic curve (AUC). RESULTS: A total of 10 362 deliveries were reviewed, with 224 cases and 278 controls included in the study. The NICHD categorizations showed reasonable discriminatory ability (AUC = 0.727). The non-NICHD parameters measured during the 30-min fetal monitoring, total deceleration area (AUC = 0.807, 95% CI: 0.770, 0.845) and total reperfusion time (AUC = 0.750, 95% CI: 0.707, 0.792), exhibited higher discriminatory ability. The slope of the descending limb of the fetal heart rate of the last deceleration curve had the best AUC value (0.853, 95% CI: 0.816, 0.889). The combination of total deceleration area or total reperfusion time with the slope demonstrated high discriminatory ability (AUC = 0.908, 95% CI: 0.882, 0.933; specificities of 71.6% and 72.7% for a sensitivity of 90%). CONCLUSIONS: The slope of the descending limb of the fetal heart rate of the last deceleration curve is the strongest predictor of fetal acidosis, but its combination with the total reperfusion time shows better clinical utility.

Personalized Model to Predict Small for Gestational Age at Delivery Using Fetal Biometrics, Maternal Characteristics, and Pregnancy Biomarkers: A Retrospective Cohort Study of Births Assisted at a Spanish Hospital.

Small for gestational age (SGA) is defined as a newborn with a birth weight for gestational age < 10th percentile. Routine third-trimester ultrasound screening for fetal growth assessment has detection rates (DR) from 50 to 80%. For this reason, the addition of other markers is being studied, such as maternal characteristics, biochemical values, and biophysical models, in order to create personalized combinations that can increase the predictive capacity of the ultrasound. With this purpose, this retrospective cohort study of 12,912 cases aims to compare the potential value of third-trimester screening, based on estimated weight percentile (EPW), by universal ultrasound at 35−37 weeks of gestation, with a combined model integrating maternal characteristics and biochemical markers (PAPP-A and ß-HCG) for the prediction of SGA newborns. We observed that DR improved from 58.9% with the EW alone to 63.5% with the predictive model. Moreover, the AUC for the multivariate model was 0.882 (0.873−0.891 95% C.I.), showing a statistically significant difference with EPW alone (AUC 0.864 (95% C.I.: 0.854−0.873)). Although the improvements were modest, contingent detection models appear to be more sensitive than third-trimester ultrasound alone at predicting SGA at delivery.

Total intrapartum fetal reperfusion time (fetal resilience) and neonatal acidemia.

OBJECTIVE: The main objective is to study the predictive capacity of intrapartum total fetal reperfusion (fetal resilience) by itself or in combination with other parameters as a predictor of neonatal acidemia. STUDY DESIGN: A retrospective case-control study was carried out at the Miguel Servet University Hospital (Zaragoza, Spain) on a cohort of 5694 pregnant women between June 2017 and October 2018. Maternal, perinatal, and cardiotocographic records were collected. Two reviewers blindly described the monitors with the American College of Obstetricians and Gynecologists (ACOG) categorizations and parameters and the non-ACOG parameters. Neonatal acidemia was defined as pH <7.10. The parameters analyzed to predict acidemia were evaluated using the sensitivity for specificity 90% value, and the area under the receiver operating characteristic curve. RESULTS: We recorded 192 infants with acidemia, corresponding to a global acidemia rate of 3.4%. Of these, 72 were excluded for lack of criteria, leaving 120 patients with arterial acidemia included in the study and 258 in the control group. The sensitivity (specificity 90%) of detection of acidemia was 42% for the ACOG III categorization (AUC, 0.524: 95% CI, 0.470-0.578), 24% for fetal reperfusion (AUC, 0.704: 95% CI, 0.649-0.759), 27% for total area of decelerations (AUC, 0.717: 95% CI, 0.664-0.771) and 50% for the multivariate model built from total reperfusion time (AUC, 0.826: 95% CI, 0.783-0.869). The total reperfusion time corresponding to a false negative rate of 10% is 23.75 min, with 28% of fetuses above this time. The AUC and sensitivity for a false negative rate of 10% are equivalent for deceleration area and time of reperfusion (p = .504). CONCLUSION: The total reperfusion time (fetal resilience) and total deceleration area are non-ACOG parameters with a good predictive ability for neonatal acidemia, higher than the ACOG III classification and without statistical differences between them. The discrimination ability of total reperfusion time can be improved using a multivariate model. As a cutoff for its use we suggest 23.75 min in 30 min corresponding to an acidemic classification rate of 90%. New parameters in combination with other maternal, obstetrics, or fetal variables, are required for the interpretation of fetal well-being.

Obstetric and perinatal outcomes of pregnancies with COVID 19: a systematic review and meta-analysis.

OBJECTIVE: This meta-analysis aimed at comparing obstetric and perinatal outcomes in laboratory-tested pregnant women for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection before delivering. METHOD: We performed a comprehensive systematic review of electronic databases for studies reporting pregnant women with and without SARS-CoV-2 infection, as determined by polymerase chain reaction (PCR) before delivery, during the pandemic period published up to June 25, 2021. Results are reported as mean difference (MD) or odds ratio (OR) and their 95% confidence interval (CI). RESULTS: Seventeen observational studies with low to moderate risk of bias, reported on 2,769 pregnant women with a positive SARS-CoV-2 PCR test and 13,807 with a negative test. Pregnant women with a positive PCR test delivered at an earlier gestational age (MD -0.19; 95% CI -0.36 to -0.02 weeks), smoked less (OR 0.75; 95% CI 0.61-0.94) and were associated with higher odds for preeclampsia (OR 1.30; 95% CI 1.09-1.54), NICU admissions (OR 2.37; 95% CI 1.18-4.76), stillbirths (OR 2.70; 95% CI, 1.38-5.29), and perinatal mortality (OR 3.23; 95% CI 1.23-8.52). There were no significant differences between positive and negative tested women in terms of nulliparity, multiple pregnancies, gestational diabetes, route of delivery, labor induction, preterm birth, infant birth weight, 5 min Apgar scores < 7, small-for-gestational-age infants and fetal malformations. Eleven studies included neonatal PCR SARS-CoV-2 testing which was performed on 129 infants, of which 20 were positive. CONCLUSION: Positive SARS-CoV-2 tested pregnant women had higher odds for preeclampsia/hypertensive disorders of pregnancy, NICU admissions, stillbirths and perinatal mortality.

Diagnostic capacity and interobserver variability in FIGO, ACOG, NICE and Chandraharan cardiotocographic guidelines to predict neonatal acidemia.

OBJECTIVE: Despite its routine use in intrapartum care, the technique of fetal cardiotocography has some limitations. The aim of this study is to analyze the predictive capacity and interobserver agreement in the latest versions of four international cardiotocography guidelines: Federation of Gynecology and Obstetrics (FIGO), American College of Obstetrics and Gynecology (ACOG), the National Institute for Health and Care Excellence (NICE) and Chandraharan, used to predict neonatal acidemia. STUDY DESIGN: The last 30 min of 150 cardiotocographic records were analyzed over all the pH ranges and were blindly evaluated by three independent reviewers. The sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiver operating characteristic curve (AUC) were calculated to assess the predictive capacity of each fetal cardiotocographic guideline. The degree of interobserver agreement was evaluated with the Fleiss Kappa coefficient. RESULTS: Observers found fetal cardiotocography guidelines to have a variable sensitivity and specificity. The Chandraharan classification reached the highest sensitivity (78.79%), while ACOG had the highest specificity (95.73%). On average for the three observers, Chandraharan had the highest discrimination capacity for neonatal acidemia, although this was only moderate (AUC 0.66; 95%CI, 0.55-0.77) and did not differ significantly from the remaining guidelines. The degree of agreement among the three observers, assessed according to the Fleiss Kappa coefficient, was generally acceptable or moderate for all items and classifications, being highest with the FIGO classification (ĸ = 0.35; 95%CI, 0.28-0.41) and lowest with the ACOG (ĸ = 0.23; 95%CI, 0.16-0.30). CONCLUSION: Although all the guidelines have a moderate capacity to predict neonatal acidemia, the Chandraharan guideline has the highest capacity. This follows a different approach from the others in that it relies on interpretations of cardiotocographic traces based on fetal physiology. The degree of interobserver agreement is, in general, acceptable for the four guidelines, and is the highest for FIGO.
