Iron versus Iron and Vitamin B6 Supplementation in Treatment of Iron Deficiency Anemia during Second Trimester of Pregnancy: Quasi Experimental Trial

Background: Anemia is one of the most prevalent complications during pregnancy. It is commonly considered a risk factor for poor pregnancy outcomes and can result in complications that threaten the life of both mother and fetus, such as preterm birth, and low birth weight. There is clear evidence to support prompt treatment in all patients with iron deficiency anemia because it is known that treatment improves quality of life and physical condition as well as alleviates fatigue and cognitive deficits. Objective: The aim of the study was to evaluate the value of addition of vitamin B6 to iron in treatment of iron deficiency anemia in pregnant women during the second trimester. Patients and Methods: The study was done by giving anemia pregnant women iron therapy and vitamin B6 which represent group A and iron therapy alone which represents group B. For each pregnant woman, age, parity and gestational history were taken before treatment. All pregnant women took their allocated treatment regularly for three weeks after diagnosis of iron deficiency anemia with complete blood picture and followed up after three weeks. Results: Results of the study revealed that there was no statistically significant difference between the two groups of therapy according to the hemoglobin level before treatment (p-value = 0.734), statistically significant higher mean value in after treatment than before treatment (p-value = 0.048), there was a significant difference in the rate of change of hemoglobin (p-value = 0.011) and body mass index (p-value 0.001). Conclusion: Iron and vitamin B6 seems to increase hemoglobin level more than iron only. Thus, in pregnant women with iron deficiency anemia iron plus vitamin B6 may be considered as a more effective alternative treatment than iron only.

Validity of Different Methods to Prenatal Screening for Down’s Syndrom During First and Second Trimester Pregnancy of Chinese Women

Objective To identify and determine the optimal method to screening for fetal Down＇s syndrome （DS）. Methods Three large cohorts with 17 118, 39 903, 16 646 subjects were enrolled for the first trimester double marker （pregnancy-associated plasma protein A and free [B-human chorionic gonadotropin） screening （FTDMS）, second trimester double marker （c{-fetoprotein and free B-human chorionic gonadotropin） screening （STDMS）, and second trimester triple marker （a-fetoprotein, free 13-human chorionic gonadotropin and unconjugated estriol 3） screening （STTMS）, respectively. The sensitivity, specificity, false positive rate （FPR）, false negative rate （FNR） and the areas under ROC curves （AUCs） were estimated in order to determine the optimal screening method in women under or above 35 years old. Results For women under 35 years old, STTMS was the best method with a detection rate of 68.8% and FPR of 4.3% followed by the STDMS with a detection rate （sensitivity） of 66.7% and FPR of 4.9%. The FTDMS had a lower detection rate of 61.1% and FPR of 6.3%. For women above 35 years old, the detection rate of all the methods was similar, but STTMS method had a lowest FPR of 15.9%. For women under 35 years old AUCs were 0.77 （95% CI, 0.64 to 0.91）, 0.81 （95% CI, 0.71 to 0.91）, and 0.82 （95% CI, 0.69 to 0.96） for FTDMS, STDMS, and STTMS methods, respectively; for those above 35 years old, AUCs were 0.70 （95% CI, 0.56 to 0.83）, 0.70 （95% CI, 0.59 to 0.82）, 0.78 （95% Cl, 0.58 to 0.97） for FTDMS, STDMS and SITMS, respectively. Conclusion Findings from our study revealed that STDMS is optimal for the detection of fetal DS in pregnant women aged under 35. For individual women, if economic condition permits, STFMS is the best choice, while for women aged above 35, STTMS is the best choice in this regard.

Plasma motilin concentration in the second and third trimesters of pregnancy and postpartum

Plasma motilin concentrations were measured in 135 women during the second andthird trimesters of pregnancy and 3～5 d after delivery and the results were compared withthose of 20 healthy nonpregnant women.The mean plasma motilin concentration (323.96±125.10 ng/L) in women during the second trimester of pregnancy was lower than in healthynonpregnant women (366.12±96.23 ng/L) (P【0.05),but that was significantly higher thanin women during the third trimester of pregnancy (121.04±27.00 ng/L) (P【0.01);theplasma motilin concentration in women during 3～5d after delivery (443.05±140.79 ng/L)was significantly higher than that in pregnant women (P【0.01).The results showed thatpregnancy appears to have a profound inhibitory effect on plasma motilin,and this may partlybe responsible for the gastrointestinal hypomotility associated with pregnancy.

A Simple Procedure for Termination of Pregnancy in the Late First Trimester with Mifeprostone and Misoprostol

Purpose: To assess the efficacy of medical methods for termination of pregnancy at 9 - 12 weeks of gestation. Methods: Between December 2008 and December 2010, the 116 consecutive women received 200 mg oral mifepristone and after 24 - 36 hours they applied 800 μg vaginal misoprostol to medically terminate pregnancy. If the products of conception did not pass, three further doses of 400 μg misoprostol were given vaginally at three hours intervals to medically terminate pregnancy. Results: Of the 116 patients undergoing the procedure 104 (90%) aborted completely. Half of the patients aborted within 6 hours. After medical termination, five per cent of the women were treated because of infection, and five per cent needed a revisit to hospital because of excessive bleeding. Two women received a blood transfusion. Previous live births or previous inducted abortion is presented in the study results. Conclusions: Medical abortion at 9 - 12 weeks’ gestation is a safe alternative to surgery.

Placenta Percreta Causing Rupture of Uterus in Second Trimester of Pregnancy in Non Scarred Uterus with an Unusual Presentation: A Case Report and Review of Literature

Placenta percreta causing second trimester, spontaneous uterine rupture in non high risk women is less frequent and fewer cases have been reported in the literature. We report a case of uterine rupture in second trimester of pregnancy due to placenta percreta with non specific symptoms in otherwise uncomplicated pregnancy without any high risk factors. This case report describes the case of young woman presenting second gravid with 21 weeks pregnancy with complaints of whole abdomen pain and dysuria. Ultrasonography shows single intrauterine dead fetus;placenta was fundoposterior in upper segment, a hypoechoic area seen below the placenta suggestive of abruption placentae or placenta accreta. Suddenly patient deteriorated in two hours of hospital stay, frank hemoperitoneum detected, emergency laparotomy done, per operatively whole fundal area of uterus became papery thin and cystic on touch, a small rent seen on fundal surface of uterus. The placenta was densely adhered to the fundoposterior aspect of the uterus. Patient had emergency subtotal hysterectomy. This case highlights that placenta percreta is a rare but serious complication of pregnancy which may present in early pregnancy without any associated high risk factors for placenta percreta with unusual symptoms.

Hemorrhages in the First Trimester of Pregnancy: Etiological Aspect and Management at the Maternity Ward of the Ignace Deen National Hospital of the University Hospital of Conakry

Aims: Hemorrhages in the first trimester of pregnancy constitute a public health problem in developing countries with maternal mortality which is still very high. This is the most common reason for consultation in early pregnancy. The objectives of this study were to describe the sociodemographic characteristics of the patients, identify the etiologies, describe the management and evaluate the maternal prognosis in patients presenting with hemorrhage in the first trimester of pregnancy. Methods: This was a descriptive-type prospective study lasting 12 months from January 1 to December 31, 2020, carried out at the maternity ward of Ignace Deen National Hospital. Results: During the study period, we recorded 163 cases of hemorrhage in the first trimester of pregnancy out of 5478 deliveries, i.e. a frequency of 2.97%. The main incriminated etiologies were spontaneous abortion (46.62%), ectopic pregnancy (28.22%), hydatidiform mole (16.56%), threatened abortion (5.52%) and pregnancy stopped (3.06%). The socio-demographic profile of the patients was that of a woman in the age group of 26 - 30 years (33.12%), married (79.14%), with secondary level (35.58%), exercising a liberal profession (36.19%) and nulliparous (60.12%). More than half of the patients came directly from home (57.66%) with metrorrhagia (44.78%) and abdominal pain (33.12%) as reasons for consultation. The gestational age between 7-11SA was more represented (82.82%). Manual intrauterine aspiration (58.89%) and salpingectomy (28.22%) were the most practiced therapeutic procedures. We transfused 10.42% of patients and 20.85% received medical treatment. The maternal prognosis was good in 47.87%. The main complications recorded were anemia (38.65%) and the state of shock (10.42%). Conclusion: Hemorrhages in the first trimester of pregnancy represent an important cause of maternal morbidity in developing countries. The improvement of the maternal prognosis would pass by the early consultation in front of any case of pregnancy.

Osteoprotegerin,interleukin and hepatocyte growth factor for prediction of diabetes and hypertension in the third trimester of pregnancy

BACKGROUND Gestational diabetes mellitus(GDM)raises the risk of high blood pressure and may cause a series of life-threatening complications in pregnant women.Screening and management of GDM and gestational hypertension(GH)in pregnancy helps to control and reduce these risks and prevent adverse effects on mothers and their fetuses.Currently,the majority criteria used for screening of diabetes mellitus is oral glucose tolerance tests,and blood pressure test is usually used for the screening and diagnosis of hypertension.However,these criteria might not anticipate or detect all GDM or GH cases.Therefore,new specific predictive and diagnostic tools should be evaluated for this population.This study selected three biomarkers of osteoprotegerin(OPG),interleukin(IL)and hepatocyte growth factor(HGF)for GDM and GH predication and diagnosis.AIM To explore the feasibility of changes in placental and serum OPG,IL and HGF as tools for prediction and diagnosis of diabetes and hypertension in pregnant women.METHODS From January 2018 to January 2019,44 pregnant women with GDM and GH were selected as an observation group,and 44 healthy pregnant women were selected as a control group in the same period.Serum OPG,IL and HGF were compared between the two groups.RESULTS The levels of OPG and HGF in the observation group were lower than in the control group,and the level of IL-1βwas higher in the observation group than in the control group(all P<0.05).Furthermore,OPG and HGF were negatively associated with gestational diabetes and gestational hypertension,while IL-1βwas positively associated with GDM complicated with GH(all P<0.05).CONCLUSION The evaluation of serum OPG,HGF and IL-1βlevels in patients with coexistent gestational diabetes complicated with hypertension can predict the degree of disease and play an important role in the follow-up treatment and prognosis prediction.

Second-trimester maternal β-human chorionic gonadotropin level associated with subsequent development of pregnancy-induced hypertension

Objective:To determine whether maternal β-human chorionic gonadotropin(β-hCG) level in second-trimester may be associated with subsequent development of pregnancy-induced hypertension(PIH).Methods:Seven hundred and sixty-two women in mid-trimester were to have maternal urine β-hCG standardized concentrations and maternal serum β-hCG measurements.Their case histories were recorded and reviewed from mid-trimester to delivery.The relation was observed between maternal urine,serum markers and subsequent development of PIH.Results:Among 762 women,504 cases were normal pregnancies,42 cases had PIH,94 cases had premature rupture of membrane (PROM),69 cases had preterm delivery (PD),53 other cases were excluded by various reasons.The levels of maternal urine,serum β-hCG in PIH were (61.75±9.78) IU/L and (304.56±54.17) ng/mg respectively,which were higher significantly than normal pregnancy group ([20.65±7.61] IU/L and [146.34±47.81] ng/mg,P<0.05).When maternal serum,urine β-hCG levels ≥2 MOM(multiple of mean),the incidences of developing PIH were increased significantly as compared with those of β-hCG <2 MOM women.The incidence of PIH increased from 5.1% in pregnancies with urine β-hCG ≥2 MOM to 11.7% in cases with urine β-hCG ≥4 MOM.Conclusion:The elevation of maternal mid-trimester urine,serum β-hCG levels is not only an early signal for dysfunction of placenta but also a dangerous signal for development of PIH.Second-trimester maternal urine β-hCG measurement proves to be superior to serum marker in clinical prediction.

A perspective study and financial analysis of different protocols of second trimester maternal serum screening for Down's syndrome

Objective:To compare the efficiency and related financial parameters of the double- and triple-marker test for the second-trimester maternal serum screening for Down's syndrome. Methods:The serum samples were collected from the 2^(nd) trimester pregnant women in this hospital and were examined for three biomedical markers[alpha-fetoprotein(AFP),freeβ-human chorionic gonadotropin(freeβ-hCG) and unconjugated estriol(uE_3)]by TR-FIA.The pregnancy outcomes were followed up and screening efficiency calculated for double-marker(AFP+freeβ-hCG) and triple-marker(AFP+ freeβ-hCG+uE_3) test. Results:(1)A total of 4,707 serum samples of 2^(nd) trimester pregnancy were collected in this study,of which 4,245 pregnancy outcomes got followed up by May 30,2009,with 462 cases lost to follow-up.The follow-up rate was 90.2%.3 cases of Down's syndrome,4 cases of other chromosome abnormalities and 1 case of neural tube defect (NTD) were found.There was no medically induced miscarriage by invasive tests.(2) Detection rate and false positive rate of triple marker test for Down's syndrome screening were 66.7%and 5.26%,respectively,while those in double marker test were 33.3%and 4.01%,respectively.The detection rate of all chromosome abnormalities was 75%in triple marker test and 37.5%in double marker test.The detection rate of NTD was 100%either in double or triple marker test.(3) It costs 499,375 RMB to avoid one Down's syndrome birth by using triple marker test and 781,200 RMB by using double marker test. Conclusion:Triple-marker test is superior to double marker test in 2nd trimester maternal serum screening for Down's syndrome,and costs less to avoid a Down's syndrome birth.

Cervical Ripening in the Third Trimester of Pregnancy with Intravaginal Misoprostol: A Double-blind, Randomized,Placebo-controlled Study

To evaluate the safety and efficacy of intravaginal misoprostol for cervical ripening in the third trimester, a randomized, double-blind, placebo-controlled trial was conducted in 85 patients indicated for induction of labor and with unfavorable cervices. They were randomly assigned to receive either intravaginal misoprostol (100 mg) or placebo placed in the posterior vaginal fornix. The Bishop score, fetal heart rate and Doppler blood flow velocity waveforms were measured before and 12 h after drug administration. Placenta and decidu were histopathologically observed in some cases. Among 85 patients enrolled, 43 received misoprostol and 42 received placebo. Whereas the mean initial Bishop scores were not significantly different between the two growps, the mean Bishop score in misoprostol group was significantly better than those in placebo group.The mean change in Bishop score was also significantly different (4. 4 for misoprostol versus 1. 0 for placebo, P<0.01 ). The prevalence of spontaneous onset of labor within 12 h after drug insertion in misoprostol group (67. 4%, 29/43)was significantly higher than that in placebo group (14. 3%, 6/42), P<0.01.The average DOppler velocity systolic to diastolic (S/D) ratios of umbilical artery,middle cramal artery, renal artery were not significantly different before and 12 h after drug insertion between both groups. There was no significant difference in frequency of abnormal fetal heart rate tracings or fetal distress and in the mean Apgar scores between the two groups. Except the presence of vasodilation in villi vessels in the misoprostol group, the placental and decidual histopathological changes had no significantly difference between two groups. It is concluded that intravaginal misoprostol may be an effective and safe cervical ripening agent in the third trimester of pregnancy.

Value of α-fetoprotein,β-HCG, inhibin A, and UE3 at second trimester for earlyscreening of preeclampsia

Objective: To study the value ofα-fetoprotein (α-FP),β-human chorionic gonadotropin (β-HCG), inhibin A, and uncojugated estriol (UE3) at the second trimester for early screening of preeclampsia. Methods: This cohort study was performed on 1713 consecutive pregnant women with gestational age from 15 to 18 weeks. We measured the serum levels ofα-FP, β-HCG, inhibin A, and UE3 and they were followed-up for 48 h after delivery. Results: A total of 1713 women were recruited and through the study 151 women (8.8%) were diagnosed with preeclampsia (n=123, 21.5% in the pregnant women with high risk, n=28, 2.5% in the pregnant women with low risk;P<0.0001). The area under receiver operating characteristic curve was estimated to be 2.39 MOM forα-FP, 2.84 MOM forβ-HCG, 1.92 MOM for inhibin A, and 0.77 MOM for UE3. The best cutoff value was specifically considered for each marker that was determined a positive predictive value ranged 19.60% forα-FP, 17.62% for β-HCG, 18.33% for inhibin A and 14.88% for UE3, a negative predictive value ranged 95.63% for α-FP, 93.89% for β-HCG, 94.28% for inhibin A and 93.57% for UE3, and an area under receiver operating characteristic curve ranged 0.70 forα-FP, 0.63 forβ-HCG, 0.65 for inhibin A and 0.61 for UE3. Conclusions: This study reveals that the new cutoff values are more valuable in screening preeclampsia. Although these markers have a low positive predictive value, they present a high negative predictive value. Also, the combination ofα-FP,β-HCG and inhibin A and the combination ofα-FP and inhibin A have the highest value in screening preeclampsia.

Quality Control of Second Trimester Ultrasound Examinations in the Gynecology and Obstetrics Department of the University Teaching Hospital Yalgado Ouedraogo (UTH-YO) of Ouagadougou, Burkina Faso

Objective: To evaluate the quality of second trimester ultrasound examinations in patients consulting in the gynecology and obstetrics department at the University Teaching Hospital Yalgado Ouedraogo (UTH-YO) of Ouagadougou. Method: Our study took place from January 1st to March 31st 2017, in the department of Obstetrics and Gynecology of the University Teaching Hospital Yalgado Ouedraogo of Ouagadougou. This was a descriptive study on the records of the second trimester ultrasound of pregnancy, with analysis of the iconography. We used the criteria of the Technical Committee of Fetal Echography (TCFE) of France to analyse all the ultrasound reports brought by the patients. Results: Three hundred ultrasound reports were collected over three months. It revealed that, in terms of patient identification, 100% of the reports bore the surname and first name of the pregnant woman;88% and 94.67% of the ultrasound scans bore the surname and first name of the ultrasound specialist respectively. Only 2% presented the brand and type of ultrasound scanner. The study of the quality of the appointment showed that 52% of the ultrasounds had been performed at the right time, between 20 Gestational Age (GA) and 25 GA. For the quality of the iconography, referring to the recommendations of the Technical Committee of Fetal Echography (TCFE) of France and taking into account the data confirmed by the literature, we found that the quality was slightly acceptable either respectively for biometric and morphological sections. Conclusion: The quality of the ultrasound reports of the second trimester ultrasounds in patients consulting in the obstetrics and gynecology department of the University Hospital Yalgado OUEDRAOGO was not totally satisfactory.

First Trimester Pregnancy Loss May Temporary Reduce the Ovarian Response during the Subsequent IVF Cycle

The aim of this study was to compare the in vitro fertilization (IVF) cycles ended by miscarriage with subsequent IVF cycles in relation to various IVF cycle parameters and pregnancy termination modalities. Comparison of pre-miscarriage to post-miscarriage IVF cycles parameters demonstrated that lower peak E2 levels (1087 ± 593 versus 1237 ± 676 pg/ml, respectively;p p p p p p < 0.05), and an increase in the conception rate (34.7% versus 42.2%, respectively) at the second post-miscarriage IVF cycle.

Contribution to the Study of Hemorrhages in the Third Trimester of Pregnancy, Etiology and Management

Third trimester bleeding is a common concern in obstetrics. The main objective of this work was to study the management of hemorrhages in the third trimester of pregnancy in the maternity ward of the Sominé Dolo hospital in Mopti. Our prospective descriptive cross-sectional survey type study conducted at the maternity ward of Sominé Dolo hospital in Mopti over a period from January 1, 2017 to December 31, 2017 included 94 cases collected. During this period we had performed 1485 deliveries including 94 cases of pregnancies complicated by 3rd trimester hemorrhage, a frequency of 6.33%. The main cause of hemorrhage in the third trimester was represented by placenta preavia 42.6% followed by retroplacental hematoma 28.7%, uterine rupture 26.6% and association Placenta preavia and retroplacental hematoma 2.1%. The type of intervention depended on the cause of the hemorrhage and the maternal and fetal condition. More than half of the cases of uterine rupture 52% had benefited from a hysterorrhaphy during a laparotomy (n = 13/25) against 48% from hysterectomy (n = 12/25). Caesarean section was performed in 87.5% (n = 35/40) against 12.5% vaginal delivery (n = 5/40) in case of placenta preavia. In the end, in 74% of cases (n = 20/27) of retroplacental hematoma, first-line cesarean section was performed. The maternal prognosis was represented by a mortality rate of 12% (n = 11/94) and morbidity dominated by hypovolemic shock 48.9% (n = 22/94), infections 28.8% (n = 13/94) and coagulopathy 11.1% (n = 5/94). The fetal prognosis was very poor. More than half (55%) of the newborns had succumbed against 45% of the newly born. In 55.3% of cases neonatal mortality occurred antenatally. Neonatal morbidity was represented by prematurity, i.e. 20.2% (n = 19/94) and low birth weight, i.e. 22.3% (n = 21/94).

Cardio-metabolic risk and adverse pregnancy outcomes in the first trimester:findings from the Shenzhen birth cohort study

Objective To investigate the relationship between cardio-metabolic abnormalities in the first trimester and adverse pregnancy outcomes(APO).Methods This cohort study recruited singleton pregnancies in the first trimester(6-13^(+6)weeks of gestation)from Shenzhen Maternal and Child Health Care Hospital between January 1,2021,and October 31,2022.Cardiometabolic markers,including body mass index(BMI),blood pressure,fasting plasma glucose(FPG),high-density lipoprotein cholesterol(HDL-C),and triglycerides(TG),were recorded during the first trimester.Incidence of APO,including gestational hypertension,preeclampsia,gestational diabetes mellitus,preterm birth,fetal growth restriction,small for gestational age infant,and placental abruption,was documented.

Spontaneous Abortions in the Second Trimester of Pregnancy: Research and Analysis of Factors Associated at Laquintinie Hospital in Douala

Introduction: Spontaneous abortion of the second trimester is an interruption of pregnancy with complete expulsion or not of the product of conception between 15 and 28 weeks of pregnancy without any maneuvers. The objective of our study was to determine the factors associated with second trimester spontaneous abortions at Laquintinie Hospital in Douala. Methodology for this purpose: We conducted a case-control study from January to May 2019 on pregnant women who may or may not have had spontaneous second trimester abortions. Results: In total we recorded 1609 pregnancies and recruited 184 patients, including 46 cases and 138 controls;which gave a frequency of spontaneous abortion in the second trimester of pregnancy of 2.85%. A correlative analysis showed that spontaneous abortions in the second trimester were associated with housewife status (OR = 2.89;CI = 1.21 - 6.79;p = 0.010), gestation > 5 (OR = 4.09;CI = 1.02 - 17.66;p = 0.040), multiparity (OR = 3.81;CI = 1.59 - 9.16;p = 0.002), history of endouterine maneuvers (OR = 5.64;CI = 2.43 - 13 .03;p = 0.000), malaria in pregnancy (OR = 3.99;CI = 1.1 - 14.76;p = 0.030), incompleteness on the second trimester ultrasound (OR = 2.37;CI = 1.18 - 4.70;p = 0.010), jolts when traveling (OR = 46.04;CI = 17.29 - 123.66;p = 0.000), long car journeys (OR = 7.05;CI = 1.99 - 27.77;p = 0.000). After logistic regression eliminating the confounding factors, only the following were associated with abortions: Multiparity (OR = 13.90;CI = 2.96 - 65.18;p = 0.000), endo uterine maneuvers (OR = 3.69;CI = 1. 01 - 13.44;p = 0.047), jolts when traveling (OR = 72.63;CI = 19.47 - 270.96;p = 0.000), long car journeys (OR = 15.41;CI = 2.7 - 85, 95;p = 0.000). Conclusion: Our study reveals that a set of factors contribute to the occurrence of spontaneous abortions in the second trimester of pregnancy in our context.

Assessment of fetus during second trimester ultrasonography using HDlive software:What is its real application in the obstetrics clinical practice?

AIM To show imaging results from application of fourdimensional(4D) ultrasound lightening technique(HDlive^(TM)) in clinical obstetrics practice. METHODS Normal and abnormal fetuses at second and third trimester of pregnancy undergoing routine scan with 4D HDlive^(TM)(5DUS) in the rendering mode are described. Realistic features of fetal structures were provided by 5DUS in the rendering mode. Normal anatomy as well as pathology like cleft lip, hypoplastic face, micrognathia, low-set ears, corpus callosum, arthrogryposis, aortic arch, left congenital diaphragmatic hernia are highlighted in this study. Anatomical details of the fetuses were provided by 5DUS with higher quality imaging modality compared to those obtained using conventional 2D/3D ultrasound. RESULTS Realistic views of fetal anatomy details were displayed by means of 5DUS in the rendering mode, with high image quality obtained either in low-risk or in high-risk obstetrics population. Corpus callosum, esophagus, and aortic arch were obtained in normal fetuses. Cleft lip, cleft lip and palate, micrognathia, hypoplastic face, lowset ears, arthrogryposis, left congenital diaphragmatic hernia, exomphalos, and clitoris hypertrophy were clearly rendered by 5DUS application.CONCLUSION The use of 5DUS in the rendering mode, when clinical available, was diagnostic in a variety of congenital anomalies, aided understanding of the parents-tobe and improved prenatal counseling and perinatal management.

Risk Stratification in Obstetrics: An Integrated Approach to Maternal Health

Introduction: Prenatal care is crucial for maternal and fetal health, highlighting the importance of obstetric risk stratification. This enables personalized care, avoiding unnecessary interventions and reducing costs. Conditions such as first trimester bleeding, spontaneous abortion, gestational trophoblastic disease, and ectopic pregnancy require specific approaches. Early identification of these complications is vital, especially in urgent and emergency obstetric cases, which demand immediate hospital attention. Objective: Comprehensive review of first trimester pathologies and gestational hypertension, focusing on obstetric risks and personalized prenatal management. Methods: Literature review on bleeding and gestational hypertension. Results: The study provides a detailed analysis of pathologies associated with first trimester uterine bleeding and hypertensive disorders, focusing on obstetric risk stratification. The main causes of maternal and fetal mortality are hypertensive disorders, hemorrhages, infections, childbirth complications, and abortion. Spontaneous abortion is common, with different classifications, ranging from threatened to missed abortion. Infected abortion is a severe complication. Brazil has restrictive abortion laws, but many unsafe abortions occur, resulting in high public health costs. Pharmacological treatment with misoprostol is a safe option. Other pathologies include gestational trophoblastic disease, ectopic pregnancy, and placenta previa. Preeclampsia and eclampsia are severe conditions requiring immediate treatment to avoid complications. Conclusion: Early identification and management of obstetric risk factors, such as uterine bleeding, are essential for positive maternal and fetal outcomes. A multidisciplinary approach is fundamental.
