Trends of Publications and Country Rankings in Pediatrics, Perinatology, and Child Health from Asia: A Bibliometric Study from 1996 to 2022.

There is a need to analyze the trends of country-wise research output in child heath over the past few decades. A total of 7,87,812 global publications in pediatrics, perinatology and child health were found from 1996 to 2022 in SCOPUS, the largest abstract and citation database of peer-reviewed literature, covering over 35,000 journals from diverse disciplines. About 13.4% of these were published from Asia. There was an average growth of global publications of 3.53 times between 1996 and 2022, with China and India showing higher growth than the global average.

Secuencia anemia-policitemia en la gestación monocorial. Manejo prenatal y resultados perinatales / Twin anaemia polycythemia polycythemia sequence in monochorionic gestation. Prenatal management and perinatal outcomes

Introducción: El objetivo de este trabajo consiste en describir y analizar los resultados perinatales de una serie de casos de anemia-policitemia (TAPS) seguidos y tratados en un centro de referencia en Medicina Fetal, en términos del tipo TAPS y la conducta prenatal aplicada. Métodos: Análisis estadístico descriptivo e inferencial con el programa IBM SPSS Statistics. Resultados: Se diagnosticaron 13 casos de TAPS en un total de 510 gestaciones monocoriales. La mayoría de TAPS espontáneos se diagnosticaron en estadios precoces (5 casos), mientras que, en TAPS posláser, 3/6 casos se diagnosticaron en estadios avanzados. Cuatro fetos (4/26; 15,4%) presentaron alteraciones en la neurosonografía, 3 (3/14; 21,4%) en TAPS espontáneos y uno (1/12, 8,3%) en TAPS posláser (p = 0,308). Se detectó hipertrofia miocárdica en 7 fetos, 5 (71,4%) de los cuales correspondían a TAPS en estadios avanzados. Cuatro eran TAPS espontáneos (4/14; 28,6%) y 3 TAPS posláser (3/12; 25%) (p = 0,797). Ocho casos (8/13; 62,5%) precisaron algún procedimiento de terapia fetal. Se produjeron 3 muertes fetales anteparto y una pareja decidió interrupción legal del embarazo (19,23%). Las 5 pérdidas se produjeron en estadio IV (p=0,008).La supervivencia global fue del 80,8% (21/26 recién nacidos vivos). No hubo diferencias significativas en función del tipo TAPS (p = 0,159) y la conducta prenatal adoptada (p = 0,746). Conclusiones: El TAPS espontáneo es, por tanto, una entidad clínica con un impacto en los resultados perinatales similar al posláser. Parece que la conducta expectante y el láser consiguen mayor edad gestacional al nacimiento.(AU)

Introduction: The aim of this paper is to describe and analyze the perinatal outcomes of a series of TAPS cases followed and treated in a Fetal Medicine referral center, in terms of the type of TAPS and the prenatal behavior applied. Methods: Descriptive and inferential statistical analysis with IBM SPSS Statistics software. Results: Thirteen cases of TAPS were diagnosed in a total of 510 monocorial gestations. Most of the spontaneous TAPS were diagnosed at early stages (5 cases), whereas, in post-laser TAPS, 3/6 cases were diagnosed at advanced stages. Four fetuses (4/26; 15.4%) presented alterations in neurosonography, 3 (3/14; 21.4%) in spontaneous TAPS and one (1/12, 8.3%) in post-laser TAPS (P=0.308). Myocardial hypertrophy was detected in 7 fetuses, 5 (71.4%) of which corresponded to advanced stage TAPS. Four were spontaneous TAPS (4/14; 28.6%) and 3 were post-laser TAPS (3/12; 25%) (P=0.797). Eight cases (8/13; 62.5%) required some fetal therapy procedure. There were 3 antepartum fetal deaths and one couple decided to legally terminate the pregnancy (19.23%). All 5 losses were stage IV (P=0.008). Overall survival was 80.8% (21/26 live newborns). There were no significant differences according to the type of TAPS (P= 0.159) and the prenatal behavior adopted (P=0.746).Conclusions: Spontaneous TAPS is therefore a clinical entity with an impact on perinatal outcomes similar to post-laser. It seems that expectant management and laser achieve higher gestational age at birth.(AU)

Counseling in fetal medicine: Congenital cytomegalovirus infection.

Although the clinical work-up of CMV in pregnancy has gradually become more accurate, counseling for CMV is still challenging. Despite the potential feasibility of universal prenatal serological screening, its introduction in prenatal diagnosis continues to raise concerns related to its real cost-effectiveness. Contextually, anticipating the confirmation of fetal infection earlier in pregnancy is one of the most pressing issues to reduce the parental psychological burden. Amniocentesis is still the gold standard and recent data have demonstrated that it could be performed before 20 weeks of gestation, provided that at least 8 weeks have elapsed from the presumed date of maternal seroconversion. New approaches, such as chorionic villus sampling (CVS) and virome DNA, even if not yet validated as confirmation of fetal infection, have been studied alternatively to amniocentesis to reduce the time-interval from maternal seroconversion and the amniocentesis results. Risk stratification for sensorineural hearing loss (SNHL) and long-term sequelae should be provided according to the prognostic predictors. Nevertheless, in the era of valacyclovir, maternal high-dose therapy, mainly for first trimester infections, can reduce the risk of vertical transmission and increase the likelihood of asymptomatic newborns, but it is still unclear whether valacyclovir continues to exert a beneficial effect on fetuses with positive amniocentesis. This review provides updated evidence-based key counseling points with GRADE recommendations.

Critical congenital heart disease: contemporary prenatal screening performance and outcomes in a multi-centre perinatology service.

BACKGROUND: Prenatal detection of critical congenital heart disease (CCHD) optimises perinatal decision-making and neonatal outcomes. The objective of this study was to determine the prenatal screening performance, care pathways and perinatal outcomes for prenatally and postnatally diagnosed cases of CCHD over a four-year period. STUDY DESIGN: This retrospective cohort study in a tertiary centre and its two affiliated secondary sites examined all cases of CCHD, including cases of pregnancy termination and in-utero fetal death, neonatal death and liveborn babies that underwent cardiac catheterization or surgery in the first six weeks of life. Prenatal and postnatal data were ascertained from the first trimester assessment for all patients diagnosed prenatally. Cases requiring intervention that were first identified in the postnatal period were included to determine prenatal detection rates. Follow-up for all cases of CCHD continued to one year of age. RESULTS: In a consecutive cohort of 49,950 pregnancies in a 4-year period 01/2019 to 12/2022, a prenatal diagnosis of CCHD was made in 96 cases, yielding a prevalence of 1.9 per 1000 births. The prenatal detection for right duct-dependant heart pathology and congenital heart block was 100%, 85% for left duct-dependant pathology and 93% for transposition of the great arteries (TGA). In the prenatally diagnosed group, 37% of cases were complicated by extracardiac structural abnormalities, a genetic diagnosis or both. All cases of prenatal detection were identified in the context of routine anatomy screening rather than specialist Fetal Cardiac screening services. Almost half of all pregnancies complicated by CCHD did not undergo neonatal cardiac intervention, by virtue of parental choice determined either prenatally or after birth. An additional eight babies were diagnosed with CCHD in the neonatal period, such that the prenatal detection rate for CCHD was 92% (96/104, 95% CI = 84%-96%). Survival at 1-year for infants deemed suitable for CCHD surgery was 85%. CONCLUSION: In a large unselected population, optimal rates of prenatal detection of critical congenital heart disease can be achieved by a protocolised approach to mid-trimester fetal anatomy ultrasound, underpinned by a programme of sonographer education and training. The cardiac abnormalities most likely to evade prenatal detection are left-sided obstructive lesions.

[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.

ChatGPT in maternal-fetal medicine practice: a primer for clinicians.

ChatGPT (Generative Pre-trained Transformer), a language model that was developed by OpenAI and launched in November 2022, generates human-like responses to prompts using deep-learning technology. The integration of large language processing models into healthcare has the potential to improve the accessibility of medical information for both patients and health professionals alike. In this commentary, we demonstrated the ability of ChatGPT to produce patient information sheets. Four board-certified, maternal-fetal medicine attending physicians rated the accuracy and humanness of the information according to 2 predefined scales of accuracy and completeness. The median score for accuracy of information was rated 4.8 on a 6-point scale and the median score for completeness of information was 2.2 on a 3-point scale for the 5 patient information leaflets generated by ChatGPT. Concerns raised included the omission of clinically important information for patient counseling in some patient information leaflets and the inability to verify the source of information because ChatGPT does not provide references. ChatGPT is a powerful tool that has the potential to enhance patient care, but such a tool requires extensive validation and is perhaps best considered as an adjunct to clinical practice rather than as a tool to be used freely by the public for healthcare information.

Racial and ethnic inequities in stillbirth in the US: Looking upstream to close the gap: Seminars in Perinatology.

Though stillbirth rates in the United States improved over the previous decades, inequities in stillbirth by race and ethnicity have persisted nearly unchanged since data collection began. Black and Indigenous pregnant people face a two-fold greater risk of experiencing the devastating consequences of stillbirth compared to their White counterparts. Because race is a social rather than biological construct, inequities in stillbirth rates are a downstream consequence of structural, institutional, and interpersonal racism which shape a landscape of differential access to opportunities for health. These downstream consequences can include differences in the prevalence of chronic health conditions as well as structural differences in the quality of health care or healthy neighborhood conditions, each of which likely plays a role in racial and ethnic inequities in stillbirth. Research and intervention approaches that utilize an equity lens may identify ways to close gaps in stillbirth incidence or in responding to the health and socioemotional consequences of stillbirth. A community-engaged approach that incorporates experiential wisdom will be necessary to create a full picture of the causes and consequences of inequity in stillbirth outcomes. Investigators working in tandem with community partners, utilizing a combination of qualitative, quantitative, and implementation science approaches, may more fully elucidate the underpinnings of racial and ethnic inequities in stillbirth outcomes.

Normal values of the fronto-occipital relationship in fetuses between 18 and 40 weeks at two maternal fetal medicine units: Bogotá, Colombia.

OBJECTIVE: To establish nomograms for linear measurements of the frontal and occipital horns of the lateral ventricle and their relationship, in pregnant patients between 18 and 40 weeks of gestation and having attended 2 units of Maternal Fetal Medicine in Bogotá-Colombia. METHODOLOGY: A descriptive cross-sectional study with an analytical component was carried out on pregnant patients who utilized the ultrasound services at 2 Maternal-Fetal Medicine units in Bogotá, between 18 and 40 weeks of pregnancy who underwent measurement. From the anterior and posterior horns of the lateral ventricles, the fronto-occipital ratio was calculated at each gestational week, and nomograms were created for each of these variables. RESULTS: Nine hundred and seventy-eight patients were included in the study. The distance of the frontal horns ranged between 6.9 and 51.6 mm with a mean of 19.1 ± 5.8 mm; that of the occipital horns had a measurement between 8.7 and 53 mm with a mean of 28, 1 ± 8.9 mm; on the other hand, the fronto-occipital ratio (FOR) yielded a mean of 0.365 ± 0.067 (0.136-0.616) without bearing any relation to gestational age. The trend of normal values for the studied population is displayed, plotted in percentile curves and nomograms for each gestational age. CONCLUSION: The measurement of the frontal and occipital horns, and the calculation of the fronto-occipital relationship is technically possible between 18 and 40 weeks, finding that the anterior and posterior horns have a positive linear relationship with gestational age. Contrarily, the FOR does not correlate with the gestational age, it was possible to establish a table of percentiles that allows determining the normal values for these measurements during pregnancy.

Society for Maternal-Fetal Medicine Special Statement: Clinical quality measures in obstetrics.

This article provides an updated overview and critique of clinical quality measures relevant to obstetrical care. The history of the quality movement in the United States and the proliferation of quality metrics over the past quarter-century are reviewed. Common uses of quality measures are summarized: payment programs, accreditation, public reporting, and quality improvement projects. We present listings of metrics that are reported by physicians or hospitals, either voluntarily or by mandate, to government agencies, payers, "watchdog" ratings organizations, and other entities. The costs and other burdens of extracting data and reporting metrics are summarized. The potential for unintended adverse consequences of the use of quality metrics is discussed along with approaches to mitigating adverse consequences. Finally, some recent attempts to develop simplified core measure sets are presented, with the promise that the complex and burdensome quality-metric enterprise may improve in the near future.

Incidence of neonatal morbidity in small-for-gestational-age twins based on singleton and twin charts.

OBJECTIVE: To compare morbidity, as measured by length of stay in the neonatal intensive care unit (NICU), in twin and singleton gestations classified as small-for-gestational age (SGA) according to estimated fetal weight < 10th percentile on twin or singleton growth charts. METHODS: NICU length of stay was compared in 1150 twins and 29 035 singletons that underwent ultrasound assessment between 35 + 0 and 36 + 6 weeks' gestation. Estimated fetal weight was obtained from measurements of head circumference, abdominal circumference and femur length using the Hadlock formula. Gestational age was derived from the first-trimester crown-rump length measurement, using the larger of the two twins. Singletons and twins were compared in terms of NICU admission rate and length of stay according to classification as SGA by the Fetal Medicine Foundation singleton and twin reference distributions. RESULTS: The overall proportions of twins and singletons admitted to NICU were similar (7.3% vs 7.4%), but twins tended to have longer lengths of stay in NICU (≥ 7 days: 2.4% vs 0.8%; relative risk (RR), 3.0 (95% CI, 1.6-4.4)). Using the singleton chart, a higher proportion of twins were classified as SGA compared with singletons (37.6% vs 7.0%). However, the proportion of SGA neonates entering NICU was similar (10.2% for twins and 10.1% for singletons) and the proportion of SGA neonates spending ≥ 7 days in NICU was substantially higher for twins compared with singletons (3.7% vs 1.4%; RR, 2.6 (95% CI, 1.4-4.7)). CONCLUSIONS: When singleton charts are used to define SGA in twins and in singletons, there is a greater degree of growth-related neonatal morbidity amongst SGA twins compared with SGA singletons. Consequently, singleton charts do not inappropriately overdiagnose fetal growth restriction in twins and they should be used for monitoring fetal growth in both twins and singletons. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Validation of Fetal Medicine Foundation competing-risks model for small-for-gestational-age neonate in early third trimester.

OBJECTIVE: To evaluate the new 36-week Fetal Medicine Foundation (FMF) competing-risks model for the prediction of small-for-gestational age (SGA) at an earlier gestation of 30 + 0 to 34 + 0 weeks. METHODS: This was a retrospective multicenter cohort study of prospectively collected data on 3012 women with a singleton pregnancy undergoing ultrasound examination at 30 + 0 to 34 + 0 weeks' gestation as part of a universal screening program. We used the default FMF competing-risks model for prediction of SGA at 36 weeks' gestation combining maternal factors (age, obstetric and medical history, weight, height, smoking status, race, mode of conception), estimated fetal weight (EFW) and uterine artery pulsatility index (UtA-PI) to calculate risks for different cut-offs of birth-weight percentile and gestational age at delivery. We examined the accuracy of the model by means of discrimination and calibration. RESULTS: The prediction of SGA < 3rd percentile improved with the addition of UtA-PI and with a shorter examination-to-delivery interval. For a 10% false-positive rate, maternal factors, EFW and UtA-PI predicted 88.0%, 74.4% and 72.8% of SGA < 3rd percentile delivered at < 37, < 40 and < 42 weeks' gestation, respectively. The respective values for SGA < 10th percentile were 86.1%, 69.3% and 66.2%. In terms of population stratification, if the biomarkers used are EFW and UtA-PI and the aim is to detect 90% of SGA < 10th percentile, then 10.8% of the population should be scanned within 2 weeks after the initial assessment, an additional 7.2% (total screen-positive rate (SPR), 18.0%) should be scanned within 2-4 weeks after the initial assessment and an additional 11.7% (total SPR, 29.7%) should be examined within 4-6 weeks after the initial assessment. The new model was well calibrated. CONCLUSIONS: The 36-week FMF competing-risks model for SGA is also applicable and accurate at 30 + 0 to 34 + 0 weeks and provides effective risk stratification, especially for cases leading to delivery < 37 weeks of gestation. © 2023 The Authors.

Society for Maternal-Fetal Medicine Special Statement: Emergency checklist, planning worksheet, and system preparedness bundle for placenta accreta spectrum.

Placenta accreta spectrum is a life-threatening complication of pregnancy that is underdiagnosed and can result in massive hemorrhage, disseminated intravascular coagulation, massive transfusion, surgical injury, multisystem organ failure, and even death. Given the rarity and complexity, most obstetrical hospitals and providers do not have comprehensive expertise in the diagnosis and management of placenta accreta spectrum. Emergency management, antenatal interdisciplinary planning, and system preparedness are key pillars of care for this life-threatening disorder. We present an updated sample checklist for emergent and unplanned cases, an antenatal planning worksheet for known or suspected cases, and a bundle of activities to improve system and team preparedness for placenta accreta spectrum.

Patient Perception of Telemedicine in Maternal-Fetal Medicine.

Background: Maternal-fetal medicine (MFM) is a medical subspecialty that cares for patients with high-risk pregnancies. Methods: An IRB-approved survey was offered to patients in MFM offices of a tertiary health care system from March 2022 to May 2022. Demographics and responses to 15 statements about telemedicine were collected via a 5-point Likert scale. Exploratory factor analysis was performed to identify factors affecting patient perception of the telemedicine experience. We sought to examine perception of telemedicine in MFM, identify factors affecting perception, and identify whether specific demographics were associated with patients who view telemedicine appointments favorably. Results: Surveys were completed by 327 of 347 (94%) patients. A total of 233 (71%) patients felt that the telemedicine experience was equal in quality to in-person appointments, and 257 (79%) were open to telemedicine appointments in the future. Exploratory factor analysis yielded two factors: "physician attentiveness" and "technology comfort." Telemedicine was viewed favorably or neutrally for both factors. Education (lower) and marital status (single) were associated with a favorable perception of physician attentiveness. Ethnicity (Hispanic), employment status (employed), and prior telemedicine experience were associated with a favorable perception of technology comfort. Conclusion: Most patients felt the quality of telemedicine appointments was equal to those completed in person. Physician attentiveness and technology comfort affect telemedicine perception. Specific patient demographic characteristics were associated with differing perceptions of telemedicine in MFM. Our findings suggest that telemedicine is positively viewed for MFM and can be used for improving health care delivery efficiency in MFM.

Society for Maternal-Fetal Medicine Consult Series #68: Sickle cell disease in pregnancy.

Pregnant individuals with sickle cell disease have an increased risk of maternal and perinatal morbidity and mortality. However, prepregnancy counseling and multidisciplinary care can lead to favorable maternal and neonatal outcomes. In this consult series, we summarize what is known about sickle cell disease and provide guidance for sickle cell disease management during pregnancy. The following are Society for Maternal-Fetal Medicine recommendations.

Society for Maternal-Fetal Medicine Statement: Clinical considerations for the prevention of respiratory syncytial virus disease in infants.

Respiratory syncytial virus is a leading cause of lower respiratory tract illness globally in children aged <5 years. Each year, approximately 58,000 hospitalizations in the United States are attributed to respiratory syncytial virus. Infants aged ≤6 months experience the most severe morbidity and mortality. Until recently, prevention with the monoclonal antibody, palivizumab, was only offered to infants with high-risk conditions, and treatment primarily consisted of supportive care. Currently, 2 products are approved for the prevention of respiratory syncytial virus in infants. These include the Pfizer bivalent recombinant respiratory syncytial virus prefusion F protein subunit vaccine, administered seasonally to the pregnant person between 32 0/7 and 36 6/7 weeks of gestation, and the monoclonal antibody, nirsevimab, administered to infants aged up to 8 months entering their first respiratory syncytial virus season. With few exceptions, administering both the vaccine to the pregnant person and the monoclonal antibody to the infant is not recommended. All infants should be protected against respiratory syncytial virus using one of these strategies. Key considerations for pregnant individuals include examining available safety and efficacy data, weighing accessibility and availability, and patient preferences for maternal vaccination vs infant monoclonal antibody treatment. It will be critical for maternal-fetal medicine physicians to provide effective and balanced counseling to aid patients in deciding on a personalized approach to the prevention of respiratory syncytial virus in their infants.
