Abstract:

Introduction: A computer program was created to calculate intrauterine radiation doses, "FetusDose", in the frame of the dosimetric support of epidemiological studies conducted for the population of the Ural region. Summary: The paper presents the method and describes the principle of organization and functionality of the computer program. The software is designed to calculate trimester and total doses accumulated in the active marrow and extra-skeletal tissues of the fetus when it is irradiated with anthropogenic radionuclides that have accidentally contaminated the environment.

Abstract:

Utero-ovarian ligament fibroids are among the rarest sites for extrauterine leiomyomas. Broad ligament fibroids are relatively common. They can be either asymptomatic or present with chronic pelvic pain and pressure symptoms. They can be confused with an ovarian mass, broad ligament cyst or a pedunculated fibroid. There are high chances of missing it clinically. Ultrasonography, magnetic resonance imaging (MRI) and computed tomography scan are the imaging techniques used to diagnose such conditions, MRI being the most accurate in ruling out other broad ligament masses with suspected ovarian, t

Abstract:

Utero-placental bed is the cumulation of gestationally altered endometrium at the place of ovum attachment to the uterine wall. The key mechanism of this process is the cytotrophoblastic invasion. During iron deficiency anemia, an increase in the specific volume of the extravascular invasive trophoblast is taking place. Concern for the protein oxidative modification in iron deficiency anemia is due to the fact that in conditions of hypoxia, free radical processes in the blood and tissues are enhanced, and iron deficiency is additionally able to modify this problem.

Agenesis of the dorsal pancreas (ADP) is a rare congenital anomaly that occurs when the body and tail of the pancreas fail to develop from the dorsal bud in utero.

To date, fewer than 120 cases have been reported in the literature.

Abstract:

We clarified factors affecting the severity of placental abruption in motor vehicle collisions by quantitively analyzing the area of placental abruption in a numerical simulation of an unrestrained pregnant vehicle driver at collision velocities of 3 and 6 m/s. For the simulation, we constructed a novel finite element model of a small 30-week pregnant woman, which was validated anthropometrically using computed tomography data and biomechanically using previous examinations of post-mortem human subjects. In the simulation, stress in the elements of the utero–placental interface was computed, a

Abstract:

The fetal echocardiogram is useful for monitoring and diagnosing cardiovascular diseases in the fetus in utero. Importantly, it can be used for assessing prenatal congenital heart disease, for which timely intervention can improve the unborn child’s outcomes. In this regard, artificial intelligence (AI) can be used for the automatic analysis of fetal heart ultrasound images. This study reviews nondeep and deep learning approaches for assessing the fetal heart using standard four-chamber ultrasound images. The state-of-the-art techniques in the field are described and discussed. The compendium

Abstract:

The purpose of this study was to investigate the role of prenatal drug exposure on birth weight, birth length, head circumference, Apgar scores, length of gestation, and motor development (Psychomotor Development Index, PDI) scores. A meta-analytic review was conducted on 56 studies published between 1979 and June 25, 1993. There were 294 effect sizes computed using the means and standard deviations reported in each study. The composite effect sizes calculated for the growth and motor development variables were (a) –.55, p <.01, birth weight; (b) –.74, p < .01, birth length; (c) –.79, p

(Anaesthesia. 2023;78:143–146) While nonobstetric surgery during pregnancy is uncommon (<1%), it can be a serious cause for concern for mother and baby. In 2016, the American Food and Drug Administration cautioned that general anesthesia (GA) use during the third trimester of pregnancy may increase the risk of impaired neurodevelopment in children of mothers exposed. A later randomized trial found no association between short-duration general anesthesia and increased risk of childhood neurodevelopment issues. Given the vulnerable nature of fetuses in utero, the topic of anesthesia use durin

Hypoxic-ischemic (HI) studies in preterms lack reliable prognostic biomarkers for diagnostic tests of HI encephalopathy (HIE). Our group’s observations from in utero fetal sheep models suggest that potential biomarkers of HIE in the form of developing HI micro-scale epileptiform transients emerge along suppressed EEG/ECoG background during a latent phase of 6–7[Formula: see text]h post-insult. However, having to observe for the whole of the latent phase disqualifies any chance of clinical intervention. A precise automatic identification of these transients can help for a well-timed diagnosis o

Abstract:

It is well understood that sex differences exist between females and males even before they are born. These sex-dependent differences may contribute to altered growth and developmental outcomes for the fetus. Based on our initial observations in the human placenta, we hypothesised that the male prioritises growth pathways in order to maximise growth through to adulthood, thereby ensuring the greatest chance of reproductive success. However, this male-specific “evolutionary advantage” likely contributes to males being less adaptable to shifts in the in-utero environment, which then places them

AbstractAdditive manufacturing (AM) is expected to generate huge economic revenue by 2025; however, this will only be realised by overcoming the barriers that are preventing its increased adoption to end-use parts. Design for AM (DfAM) is recognised as a multi-faceted problem, exasperated by constraints to creativity, knowledge propagation, insufficiencies in education and a fragmented software pipeline. This study proposes a novel approach to increase the creativity in DfAM. Through comparison between DfAM and in utero human development, the unutilised potential of design through the time dom

Offspring of preeclampsia patients have an increased risk of developing neurological deficits and cognitive impairment. While low placental perfusion, common in preeclampsia and growth restriction, has been linked to neurological deficits, a causative link is not fully established. The goal of this study was to test the hypothesis that placental ischemia induces neuroinflammation and micro-hemorrhages in utero. Timed-pregnant Sprague Dawley rats were weight-matched for sham surgery (abdominal incision only) or induced placental ischemia (surgical reduction of utero-placental perfusion (RUPP));

Sex-specific differences in behavior have been observed in anxiety and learning in children exposed to prenatal inflammation; however, whether these behaviors manifest differently by age is unknown. This study assesses possible behavioral changes due to in utero inflammation as a function of age in neonatal, juvenile, and adult animals and presents potential molecular targets for observed differences. CD-1 timed pregnant dams were injected in utero with lipopolysaccharide (LPS, 50 μg/animal) or saline at embryonic day 15. No differences in stress responses were measured by neonatal ultrasonic

Previous research reported that prolonged benzene exposure during in utero fetal development causes greater fetal abnormalities than in adult-stage exposure. This phenomenon increases the risk for disease development at the fetal stage, particularly carcinogenesis, which is mainly associated with hematological malignancies. Benzene has been reported to potentially act via multiple modes of action that target the hematopoietic stem cell (HSCs) niche, a complex microenvironment in which HSCs and multilineage hematopoietic stem and progenitor cells (HSPCs) reside.
