Background: Hemolytic Disease of the Fetus and Newborn (HDFN) arises from blood group incompatibility, especially the RhD antigen. In Benin, systematic ABO RhD blood grouping is poorly understood by many midwives and nurses. Nearly one in ten women risk having children with HDFN. This study aimed to determine the level of knowledge of the Beninese population on HDFN. Methods: Data were collected from June 2023 to March 2024. Participants completed a Kobotoolbox questionnaire on WhatsApp, with in-person assistance for illiterate participants. The study involved 521 participants from across Benin. Data were analyzed using SigmaPlot version 14.0. Results: Among the 521 participants, 298 were women (57.20%) aged 18 to 77 years. The majority (40.69%) were aged 26 - 35. Over a third (35.51%) did not know their RhD blood group. Most (59.12%) were unaware of the risks for RhD discordant couples. Among those with a partner, 25.16% were in at-risk couples for HDFN, and over half (59.12%) were unaware of this risk. There was no significant association between being in a high-risk union and knowledge of the risk or education level. Conclusion: Only 40.88% of the Beninese population are aware of HDFN, indicating a low level of knowledge. 展开更多

To investigate the application and effectiveness of vascular corrosion technique in preparing fetal cardiovascular cast models, 10 normal fetal heart specimens with other congenital disease(control group) and 18 specimens with severe congenital heart disease(case group) from induced abortions were enrolled in this study from March 2013 to June 2015 in our hospital. Cast models were prepared by injecting casting material into vascular lumen to demonstrate real geometries of fetal cardiovascular system. Casting effectiveness was analyzed in terms of local anatomic structures and different anatomical levels(including overall level, atrioventricular and great vascular system, left-sided and right-sided heart), as well as different trimesters of pregnancy. In our study, all specimens were successfully casted. Casting effectiveness analysis of local anatomic structures showed a mean score from 1.90±1.45 to 3.60±0.52, without significant differences between case and control groups in most local anatomic structures except left ventricle, which had a higher score in control group(P=0.027). Inter-group comparison of casting effectiveness in different anatomical levels showed no significant differences between the two groups. Intra-group comparison also revealed undifferentiated casting effectiveness between atrioventricular and great vascular system, or left-sided and right-sided heart in corresponding group. Third-trimester group had a significantly higher perfusion score in great vascular system than second-trimester group(P=0.046), while the other anatomical levels displayed no such difference. Vascular corrosion technique can be successfully used in fabrication of fetal cardiovascular cast model. It is also a reliable method to demonstrate three-dimensional anatomy of severe congenital heart disease and normal heart in fetus. 展开更多

The dynamics of blood lead (Pb-B) and blood zinc protoporphyrin (ZPP-B) of women in early pregnancy and parturient women with lead exposure and the effects on fetus development were investigated. Pb-B of lead-exposed women was high: 0.984 μmol/L (20.38 μg/dl) and ZPP was 84.52μg/dl. Cord blood Pb-B was 0.896 μmol/L(18.56μg/dl)and cord blood ZPP was 69.24μg/dl. In the control group, Pb-B was 0.261μmol/L(5.41μg/dl), ZPP-B, 37.59 μg/dl, cord blood, Pb-B 0.34 μmol/L (7.93 μg/dl), and cord ZPP-B 49.0μg/dl. There was a significant correlation between blood lead and blood ZPP, maternal Pb-B and cord Pb-B, maternal Pb-B and cord ZPP-B. The significance of the consistency of high level Pb-B and the effects on fetus development is discussed. 展开更多

The present study aimed to examine the value of ultrasonic soft markers in prenatal screening by analyzing the clinical outcome of fetuses with ultrasonic soft markers during the second trimester of pregnancy. A retrospective analysis was performed to evaluate the outcome of 591 fetuses with ultrasonic soft markers from January 2015 to August 2016 in Zhongnan Hospital of Wuhan University, China. It was found that 591 fetuses showed ultrasonic soft markers in 4927 cases with the occurrence rate being 12.0%. Among them, 564 fetuses(95.4%) were delivered and the remaining 27 cases(4.6%) were aborted. Five hundred and sixty-seven cases had single ultrasonic soft marker, including echogenic intracardiac focus(n=343), mild renal pelvis dilatation(n=116), short long bones(n=72), single umbilical artery(n=31), mild lateral ventriculomegaly(n=21), choroid plexus cysts(n=19), and echogenic bowel(n=13), with the disappearing rates in pregnancy being 97.1%(333/343), 77.6%(90/116), 0%(0/72), 0%(0/31), 57.1%(12/21), 89.5%(17/19) and 61.5%(8/13) respectively. The rate of pregnancy termination due to single ultrasonic soft marker was 3.4%(19/567), and that was 33.3%(8/24) due to two ultrasonic soft markers with the difference being statistically significant(P〈0.05). The reasons of pregnancy termination included malformations(polycystic kidney, cleft lip and palate, congenital heart diseases, pcromphalus, hypospadias, hydrocephalus), chromosome abnormality, and stillbirth. It was concluded that single ultrasonic soft marker is usually transient manifestation in pregnancy. Without the other structural defects, single ultrasonic soft marker usually disappears spontaneously with favorable prognosis in a low-risk population. It is suggested that ultrasonic soft markers should be appropriately interpreted to avoid unnecessary invasive examination. 展开更多

Background: The degree of adipose tissue development at birth may influence neonatal survival and subsequent health outcomes. Despite their lower birth weights, piglets from Meishan sows(a fat breed with excellent maternal ability) have a higher survival rate than piglets from Large White sows(a lean breed). To identify the main pathways involved in subcutaneous adipose tissue maturation during the last month of gestation, we compared the proteome and the expression levels of some genes at d 90 and d 110 of gestation in purebred and crossbred Large White or Meishan fetuses gestated by sows of either breed.Results: A total of 52 proteins in fetal subcutaneous adipose tissue were identified as differential y expressed over the course of gestation. Many proteins involved in energy metabolism were more abundant, whereas some proteins participating in cytoskeleton organization were reduced in abundance on d 110 compared with d 90. Irrespective of age,24 proteins differed in abundance between fetal genotypes, and an interaction effect between fetal age and genotype was observed for 13 proteins. The abundance levels of proteins known to be responsive to nutrient levels such as aldolase and fatty acid binding proteins, as wel as the expression levels of FASN, a key lipogenic enzyme, and MLXIPL, a pivotal transcriptional mediator of glucose-related stimulation of lipogenic genes, were elevated in the adipose tissue of pure and crossbred fetuses from Meishan sows. These data suggested that the adipose tissue of these fetuses had superior metabolic functionality, whatever their paternal genes. Conversely, proteins participating in redox homeostasis and apoptotic cel clearance had a lower abundance in Meishan than in Large White fetuses. Time-course differences in adipose tissue protein abundance were revealed between fetal genotypes for a few secreted proteins participating in responses to organic substances, such as alpha-2-HS-glycoprotein, transferrin and albumin.Conclusions: These results underline the importance of not only fetal age but also maternal intrauterine environment in the regulation of several proteins in subcutaneous adipose tissue. These proteins may be used to estimate the maturity grade of piglet neonates. 展开更多

BACKGROUND We describe the treatment strategy for a patient who was found to have a partial hydatidiform mole and coexisting fetus(PHMCF)during the second trimester.The patient was a 38-year-old Chinese woman who had become pregnant following in vitro fertilization and embryo transplantation.We wanted to determine the safest therapeutic strategy to terminate the PHMCF during the second trimester.CASE SUMMARY In this case,we present a patient who was found to have a PHMCF complicated with serious continuous vaginal bleeding and pre-eclampsia during the second trimester.After careful evaluation,the pregnancy was considered to be unsustainable and was terminated via caesarean section(CS).An infant with weak vital signs and a partially cystic placenta measuring 110 mm×95 mm×35 mm were delivered by CS.The patient was discharged after 4 d.The serum levels ofβ-human chorionic gonadotropin decreased to within a normal range 5 wk after the operation,and no evidence of persistent trophoblastic disease or lung metastases was noticed at the 6-mo follow-up.CONCLUSION CS termination of PHMCF during the second trimester may be a relatively safe therapeutic strategy. 展开更多

BACKGROUND Heart defects are the most common congenital malformations in fetuses.Fetal cardiac structure and function abnormalities lead to changes in ventricular volume.As ventricular volume is an important index for evaluating fetal cardiovascular development,an effective and reliable method for measuring fetal ventricular volume and cardiac function is necessary for accurate ultrasonic diagnosis and effective clinical treatment.The new intelligent spatiotemporal image correlation(iSTIC)technology acquires high-resolution volumetric images.In this study,the iSTIC technique was used to measure right ventricular volume and to evaluate right ventricular systolic function to provide a more accurate and convenient evaluation of fetal heart function.AIM To investigate the value of iSTIC in evaluating right ventricular volume and systolic function in normal fetuses.METHODS Between October 2014 and September 2015,a total of 123 pregnant women received prenatal ultrasound examinations in our hospital.iSTIC technology was used to acquire the entire fetal cardiac volume with off-line analysis using QLAB software.Cardiac systolic and diastolic phases were defined by opening of the atrioventricular valve and the subsequent closure of the atrioventricular valve.The volumetric data of the two phases were measured by manual tracking and summation of multiple slices and recording of the right ventricular end-systolic volume and the right ventricular end-diastolic volume.The data were used to calculate the right stroke volume,the right cardiac output,and the right ejection fraction.The correlations of changes between the above-mentioned indices and gestational age were analyzed.The right ventricular volumes of 30 randomly selected cases were measured twice by the same sonographer,and the intraobserver agreement measurements were calculated.RESULTS Among the 123 normal fetuses,the mean right ventricular end-diastolic volume increased from 0.99±0.34 mL at 22 wk gestation to 3.69±0.36 mL at 35+6 wk gestation.The mean right ventricular end-systolic volume increased from 0.43±0.18 mL at 22 wk gestation to 1.36±0.22 mL at 35+6 wk gestation.The mean right stroke volume increased from 0.62±0.29 mL at 22 wk gestation to 2.33±0.18 mL at 35+6 wk gestation.The mean right cardiac output increased from 92.23±40.67 mL/min at 22 wk gestation to 335.83±32.75 mL/min at 35+6 wk gestation.Right ventricular end-diastolic volume,right ventricular end-systolic volume,right stroke volume,and right cardiac output all increased with gestational age and the correlations were linear(P<0.01).Right ejection fraction had no apparent correlation with gestational age(P>0.05).CONCLUSION Fetal right ventricular volume can be quantitatively measured using iSTIC technology with relative ease and high repeatability.iSTIC technology is expected to provide a new method for clinical evaluation of fetal cardiac function. 展开更多

The distribution of theANPlike substance in the hearts of human fetuses and rats was studied. The results were as follows:①In human fetus ANP-like substance was found throughout in the atrial wall, but more intensely in the inner layer. It lacked in the ventricular wall. ②In young rat atrum, ANP-like substance wasdistributed over the whole wall, but richer in the cells beneath the endocardium and epicardium. In adult rat atrium, distribution of ANP-like substance was more intensely beneath the epicardium than that near the lumen. In the ventricle, ANP-like substance was found only in the young rat, especially on the left side of interventricular septum (IVS). So the distribution of ANP in rat hearts changes with age. ③In the sinus node (SAN) and atrioventricular node (AVN) of both human fetuses and rats showed a small amount of ANP-like substance, and more in peripheral part of the nodes, but thereactive intensity was weaker than that of the atrial wall. The presence of ANP in conduction system may have some functional significance to influence the pulse conduction. 展开更多

Forensic research requires the application of reliable identification methods for unidentified individuals, among which the dental analysis has prime importance. The most significant source of dental evidence is oral autopsy applications, which consist of an examination and evidence collection from the oral cavity of a deceased individual. Oral autopsies show variations depending on the age of the person due to rigor mortis. The oral autopsy of a child may require an easier operation than adults, and thus, the procedures are usually simpler for fetus or infant cases. The aim of this study is to propose the theoretical and experimental aspects of an oral autopsy protocol for a special age group of fetus or infant cases, which is a method for extracting tooth germs in their developmental stages for identification purposes and entitled by the authors’ names as the “Aka-Canturk Oral Autopsy Method”. 展开更多

The developing sphenoid bone is considered to be a median cartilage mass(basilar sphenoid bone)with three cartilaginous processes(orbital wing or orbital pterygoid process,temporal wing and nasal pterygoid process).The relationship between this initial morphology and adult morphology is difficult to determine because of extensive membranous ossification along the cartilaginous elements.We examined the sagittal sections of 25 embryos and fetuses aged 6-34 weeks,and compared them with the horizontal and frontal sections of the other 25 late fetuses(217-340 mm).At 7-8 weeks,the optic nerve was sandwiched between bars of the orbitosphenoid.The superior rectus originates from a bar different from the other three recti. 展开更多

Purpose: Surfactant proteins exist in the digestive tract and may play an important role in the host defense. However, the expression of surfactant proteins in the premature digestive system remains unclear. The aim of this study was to investigate the expression of surfactant proteins in the intes-tines and pancreas of murine fetuses. Methods: Immunostaining for SP-A and SP-D was assessed in the small intestine and pancreas of ICR murine fetuses on days 15, 16, 17 and 18 of gestation (normal duration of pregnancy: 19 - 21 days). RT-PCR was performed to detect the expression of spa and spd mRNA in the small intestine and pancreas on day 16, 17 and 18 of gestation. Results: Immunoreactivity for SP-A and SP-D in the acinar cells of pancreas and intestinal mucosal surface were positive on day 16 of gestation onward. RT-PCR revealed that the expression of spa and spd mRNA was significant in the pancreas but weak in the small intestine. Conclusions: Our data revealed that surfactant proteins are present in the fetal intestines and pancreas and that a significant expression of spa and spd mRNA is detected in the fetal pancreas. Pancreas may be a possible organ involved in the synthesis and secretion of surfactant proteins into the intestinal lumen. 展开更多

The basic rhythms of nature that left their imprint on the existence of all living organism on the Earth, arose under the influence of the Earth’s rotation relative to the Sun, the Moon and other planets and stars of the Universe. This periodicity gave rise to the rhythm that has become essential for their life. Life is a continual chemical process of building up and breaking down of organic substances, which results from the substance exchange between an organism and the environment. This makes it impossible for a living organism to exist without the external environment. Since 1978-1979 we have been carrying out a task-oriented research with the aim to approximate the moment when we are able to answer all these questions. Daily fluctuations of cardiac and motor activity of the fetus have been studied (uninterrupted daily recording of fetal ECG);polysomnography of nocturnal sleep was recorded;daily fluctuations of endocrine system activity in the pregnant were studied. A correlation was made between the functional state of maternal sleep-wakefulness biological rhythm, biological clock of the human fetus and the “light-darkness” cycle of a 24-hour solar day. In the process of the study we have developed an original method of day-to-day analysis of maternal and fetal ECGs. It has been established that a healthy fetus has distinct, diurnal variations of physiological functions. The fetal biorhythms coordinate with the status of the maternal organism being, however, in an opposite phase. The curve of the dynamics of fetal physiological system functioning shows a biphasic nature (one-phase in adults). “Active” and “quiet” (sleep-like) periods have been singled out in the human fetus. No reaction is observed in “quiet” periods. However, the “zero”-type fetal reaction recorded by us within the period from 2 p.m. to 9 p.m. does not indicate unsatisfactory condition of the fetus but rather is suggestive of a definite reduction of functional levels of the fetal physiological systems, which is necessary for vital activity. Although conventionally recognized as an indicator of poor state of the fetus, this type only calls for precise attention when recorded in fetal “active” hours. The present study has been the first in the world’s medicine and biorhythmology to detect and establish the daily rhythms of cardiac and motor activity in the human fetus. 展开更多
