RESUMEN
ETHNOPHARMACOLOGICAL RELEVANCE: The popularity of herbal medicine is expanding globally due to the common belief that herbal products are natural and nontoxic. Thymelaea hirsuta leaves are traditionally used for the treatment of recurrent abortion in humans and animals. However, a lack of safety evaluation of the plant, particularly in pregnant women, raises serious concerns regarding its potential embryotoxic effects. AIM OF THE STUDY: Therefore, the present study investigated the safety of Thymelaea hirsuta leaves aqueous extract (THLE) during pregnancy and lactation following maternal rat treatment. MATERIALS AND METHODS: THLE phytochemical compounds were identified using high-performance liquid chromatography (HPLC). THLE was orally administered to pregnant rats and lactating dams at dosages of 0, 250, 500, and 1000 mg/kg/day. At the end of the study, dam s' and pups' body weights, serum biochemical and hematological indices, and histopathological changes were investigated. For the fetal observation and histopathological changes were also evaluated. RESULTS: Our findings revealed that THLE is rich in different phenolic and flavonoid compounds. However, biochemical and hormonal parameters such as ALT, AST, and prolactin were significantly increased in dams treated with a higher dosage of THLE when compared to the control dams (P ≤ 0.05). Additionally, external, visceral and skeletal examinations of fetuses revealed a marked increase of malformation rates in treated fetuses. CONCLUSIONS: The results revealed that higher oral dosing of THLE during pregnancy could affect embryonic development in rats, while lower doses are safe and can be used during pregnancy and lactation to attain its beneficial effects.

The developmental origins of healthy and disease (DOHaD) concept has demonstrated a higher rate of chronic diseases in the adult population of individuals whose mothers experienced severe maternal protein restriction (MPR). Using proteomic and in silico analyses, we investigated the lung proteomic profile of young and aged rats exposed to MPR during pregnancy and lactation. Our results demonstrated that MPR lead to structural and immune system pathways changes, and this outcome is coupled with a rise in the PI3k-AKT-mTOR signaling pathway, with increased MMP-2 activity, and CD8 expression in the early life, with long-term effects with aging. This led to the identification of commonly or inversely differentially expressed targets in early life and aging, revealing dysregulated pathways related to the immune system, stress, muscle contraction, tight junctions, and hemostasis. We identified three miRNAs (miR-378a-3p, miR-378a-5p, let-7a-5p) that regulate four proteins (ACTN4, PPIA, HSPA5, CALM1) as probable epigenetic lung marks generated by MPR. In conclusion, MPR impacts the lungs early in life, increasing the possibility of long-lasting negative outcomes for respiratory disorders in the offspring.

Pelvic endometriosis is a well-known clinical risk factor for pelvic inflammation and adhesions. We present a complex case of a woman undergoing a cesarean section where the traditional incision on the anterior lower uterine segment was not possible due to a congested pelvis. The newborn was delivered using a posterior uterine wall incision with rotation of the round ligament.

Subtle but demonstrable movements in the expectant mother's pelvis occur during vaginal delivery in all the pelvic joints and anatomical planes of the body (sagittal, frontal, and transverse). The purpose of these movements is to gradually expand the space in the lesser pelvis via widening of the individual pelvic planes so that the newborn's head can enter the pelvic inlet, safely pass through the narrow planes of the pelvis, and through the pelvic outlet. From the point of view of biomechanics, these movements are described in literature as counternutation and nutation of the sacrum and iliac bone. The counternutation of the sacrum helps to expand the plane of the pelvic inlet. The nutation of the sacrum assists in expanding the plane of the pelvic width, height, and outlet. These physiological movements are affected by the body constitution, the state of the myofascial and skeletal systems of the mother, and furthermore, by hormonal disjunction of the connections in the expectant mother's pelvis together with the progress of the delivery mechanism itself. The main factor that determines the range of movement in the individual joints, and therefore adequate expansion of the individual pelvic planes, is the position of the mother during delivery. Engagement of active movements of the mother together with application of passive stretching of the soft tissues in the lower lumbar area and in the hip joints are both needed for maximum expansion of the individual pelvic planes and utilization of the maximum useful capacity of the mother's pelvis during delivery. These movements help invoke the abduction forces on muscles, tendons, and ligaments in the pelvis that lead to the optimum setting of the joints during which delivery movements happen. The specific movements in the pelvic joints predetermine whether nutation or counternutation is possible, and therefore if the newborn's head can progress to the pelvic inlet or pass through the narrow and wide pelvic planes, and the pelvic outlet. The knowledge of these biomechanical principles and movements in the pelvis during delivery enables obstetricians and midwives to understand how the movements in the hip joints of the expectant mother can positively impact the spatial ratios in the lesser pelvis, and how to support further progress in the event of non-progressive labour.

Recent decades have seen a notable increase in cesarean section rates. Although lifesaving, cesarean delivery is associated with an elevated risk of adverse health outcomes in newborns, including respiratory diseases, atopic disorders, obesity, diabetes, and severe autoimmune conditions. The exact mechanisms underlying these associations remain elusive; however, epigenetic modifications have emerged as a plausible molecular basis linking perinatal factors with future disease susceptibility. This review summarizes current literature, revealing that the delivery method may influence epigenetic markers in neonates, primarily through alterations in global DNA methylation and gene-specific methylation patterns.

One crucial step to improving maternal health outcomes in any region is understanding the social determinants of maternal health, which vary significantly across the world´s geographical areas and within individual countries. The variability in these determinants is manifested in the Middle East and North Africa (MENA) region. Using a scoping review process, we identified articles analyzing social factors influencing maternal health outcomes in the MENA region. A total of 50 articles were included in this review. Several social factors impact independently or in association with maternal health outcomes or utilization of maternal health in the MENA region. These factors include: residing in an area of conflict, residing in a rural region, low accessibility and quality of health care, low level of education, antagonistic relationship with spouse and family-in-law, cultural practices such as female genital mutilation and early marriage, traditional practices, and beliefs, low household wealth, women´s financial security, women's bad childbirth history, and interpersonal violence. Multi-sector collaboration across governmental ministries, non-governmental organizations, local authorities, healthcare delivery programs, and community members is critical to creating long-term solutions in maternal health for MENA nations. Together they must address traditional practices harmful to women, poor accessibility, availability, and affordability of health services. To benefit women, a long-term commitment of organizations at local, national, and international levels to social investments in women´s education, financial status, and cultural norms is recommended for MENA nations.

Introduction: birth weight is a critical indicator of neonatal health and predicts future developmental outcomes. Despite its importance, there is a notable lack of research on the determinants of low birth weight (LBW) in southeast Gabon. This study aims to fill this gap by identifying factors contributing to LBW at the Centre Hospitalier Universitaire Amissa Bongo in Franceville. Methods: this retrospective analysis covered the period from February 2011 to May 2017, focusing on postpartum women and their infants. Data were analyzed using R software (version 4.3.2), employing both descriptive statistics and logistic regression. Statistical significance was determined at a p-value of less than 0.05. Results: among the 877 births analyzed, the prevalence of LBW was 8.4%. Bivariate analysis identified several factors associated with an increased risk of LBW, including, primigravida women (COR (95%CI) =0.59 (0.36-0.98), P = 0.036), primiparous women (COR (95%CI) =0.58 (0.36-0. 94), P = 0.024), women with a gestational age <37 weeks (COR (95%CI) =0.07 (0.04-0.11), P<0.001), women with ≤2 antenatal visits (COR (95%CI) =0.39 (0.18-0.93), P= 0.021), and women who underwent cesarean delivery (COR (95%CI) =0.46 (0.26-0.84), P = 0.008). However, multivariate analysis showed that only gestational age (AOR (95%CI) = 0.07 (0.04-0.11), P<0.001) and cesarean delivery (AOR (95%CI) = 0.48 (0.25-0.95), P = 0.03) were significantly associated with LBW. Conclusion: this study highlights the importance of gestational age and delivery method in the prevalence of LBW in southeast Gabon. These findings underscore the need for targeted interventions to address these risk factors, thereby improving neonatal health outcomes.

Introduction: childbirth experiences are women´s personal feelings and interpretations of birth processes, which could be difficult to describe and explain. The outbreak of Coronavirus disease (COVID-19) instilled tension and worries in all Nigerian citizens and could also affect the birth experiences and satisfaction of women. Thus, this study explored the experiences of childbirth and satisfaction with birth among women in selected Nigerian healthcare facilities during COVID-19 pandemic. Methods: the study adopted a concurrent triangulation mixed method design, which utilized an in-depth interview and questionnaire to obtain different but complementary data. Sample sizes of 304 and 15 women were recruited for quantitative and qualitative data, respectively. Analysis was done using descriptive statistics and thematic content analysis. Results: the majority of the participants perceived childbirth to be labor and delivery (3.66 ± 3.16); participants were mostly satisfied with reception received from staff (2.35 ± 2.29) and respecting their privacy (2.04 ± 1.52). Five (5) themes and 18 subthemes emerged from qualitative data. The themes were: understanding of childbirth, satisfaction with care, hospital experiences, unique experiences during birth, and social support. Conclusion: women had more positive and less negative but unique childbirth experiences. The majority expressed satisfaction within the care given by qualified and competent health workers, despite the challenges posed by COVID-19 pandemic. The provision of physical and emotional support by intimate partners, midwives´ and family members during delivery had a significant influence on maternal satisfaction with the entire birth experience.

During the first week of development, human embryos form a blastocyst composed of an inner cell mass and trophectoderm (TE) cells, the latter of which are progenitors of placental trophoblast. Here, we investigated the expression of transcripts in the human TE from early to late blastocyst stages. We identified enrichment of the transcription factors GATA2, GATA3, TFAP2C and KLF5 and characterised their protein expression dynamics across TE development. By inducible overexpression and mRNA transfection, we determined that these factors, together with MYC, are sufficient to establish induced trophoblast stem cells (iTSCs) from primed human embryonic stem cells. These iTSCs self-renew and recapitulate morphological characteristics, gene expression profiles, and directed differentiation potential, similar to existing human TSCs. Systematic omission of each, or combinations of factors, revealed the crucial importance of GATA2 and GATA3 for iTSC transdifferentiation. Altogether, these findings provide insights into the transcription factor network that may be operational in the human TE and broaden the methods for establishing cellular models of early human placental progenitor cells, which may be useful in the future to model placental-associated diseases.

BACKGROUND: The rate of recurrent spontaneous preterm delivery (sPTD) ranges between 27% and 34% and is 22.3% in Japan. Although it currently remains unclear whether probiotics prevent sPTD, retrospective studies recently reported a reduction in the rate of recurrent sPTD with the administration of probiotics including Clostridium spp., which induce regulatory T cells that play an important role in maintaining pregnancy. OBJECTIVE: The objective of this trial is to evaluate the preventative effects of available oral probiotics, including Clostridium butyricum, on recurrent sPTD. METHODS: This is a prospective, single-arm, nonblinded, multicenter trial in Japan. The sample size required for this trial is 345 pregnant women with a history of sPTD, considering a clinically significant reduction in the relative risk of 30% (risk ratio=0.7). The primary endpoint is the rate of recurrent sPTD at <37 weeks of gestation. The secondary endpoints are the rate of sPTD at <34 weeks of gestation, the rate of recurrent sPTD at <28 weeks of gestation, the ratio of intestinal Clostridium spp. (detected by next-generation sequencing), and bacterial vaginosis (using the Nugent score). RESULTS: The trial procedures were approved by the Clinical Research Review Board of Toyama University Hospital (SCR2020008) on March 31, 2021. The trial was registered on the Japan Registry of Clinical Trial website on April 28, 2021. Recruitment began on May 1, 2021, and the trial is estimated to finish on March 31, 2025. CONCLUSIONS: The findings will clarify the rate of recurrent sPTD following probiotic administration including Clostridium butyricum. Outcomes from this trial will inform clinical practice and guide future randomized controlled trials.

Neotropical freshwater stingrays of the subfamily Potamotrygoninae exhibit aplacental viviparity with uterine trophonemata. In this reproductive mode, females nourish and provide oxygenation to the embryo via the mucosa of the uterine wall. The aim of this study was to describe and histologically quantify the tissue components of the gravid uterus in an Amazonian freshwater stingray. Adult females of Potamotrygon wallacei were studied in different reproductive periods: resting stage, pregnant, and postpartum. During reproductive rest, the left ovary has numerous follicles compared to the right side. Therefore, uterine fertility is usually higher on the left side. The presence of an embryo in the right uterus suggests that the right ovary is also functional, although this only occurs in larger females. In females at reproductive rest, the wall of the uterus is formed by a mucosal layer (without the trophonemata) that contributes 16.7% to the thickness, while the myometrium accounts for 83.3% of the thickness. The mass-specific volume of the mucosal layer, inner circular, and outer longitudinal smooth muscle sheets tend to increase in the gravid uterus, indicating hypertrophy and hyperplasia of these components. During pregnancy, the trophonemata undergo marked tissue remodeling. Epithelial cells are organized into glandular acini and have apical secretory vesicles; furthermore, peripheral blood vessels proliferate and become dilated. These characteristics demonstrate that the gravid uterus of P. wallacei presents intense uterolactation activity and provides oxygenation to the fetus. Tissue remodeling occurs only in the uterus with the presence of an embryo. During postpartum, females have low body condition factor indicating a high reproductive cost. This study contributes to the knowledge of the reproductive biology of this species and will help us understand the impacts of climate change on the breeding areas of potamotrygonids.

RATIONALE: Pregnancy is a special term in life with physiological changes in both cardiorespiratory and immune systems; that is why severe acute respiratory syndrome coronavirus 2 infection in pregnancy may result in an altered response. With this, we present a case report of a young pregnant lady who was exposed to severe acute respiratory syndrome coronavirus 2 infection just before pregnancy and ended up with an affected fetus. The impact of coronavirus disease 2019 (COVID-19) exposure on neonatal outcomes has not yet been fully evaluated; by this article, we aim to find if COVID-19 exposure is linked to congenital anomalies. PATIENT CONCERNS: A 25-year-old woman who has no history of genetic or chronic diseases applied to our clinic for routine control of pregnancy. She does not have a consanguineous marriage or any other potential risk factors for pregnancy. DIAGNOSES AND INTERVENTIONS: She had a history of COVID-19 polymerase chain reaction positivity 2 days before the first day of the last menstruation period and hospitalization for 7 days. After 7 days of treatment with favipiravir and levofloxacin, enoxaparin sodium, famotidine, paracetamol, budesonide, dornaz alfa, and vitamin C; her general situation gets better, and discharged from the hospital on the seventh day of hospitalization without any further treatment prescription. OUTCOMES: During her routine controls for pregnancy at first-trimester evaluation ultrasonography; there was right forearm aplasia and deformities at both feet and legs. LESSONS: In the literature, there is conflicting evidence about the impact of COVID-19 in pregnancy especially if the patient is confronted with the virus in the first trimester. Despite the increasing number of published studies on COVID-19 in pregnancy, there are insufficient good quality unbiased studies about the issue. Risk factors for COVID-19 overlap with the risk factors for pregnancy complications and the risk factors of the treatment prescribed. The impact of COVID-19 exposure on neonatal outcomes has not yet been fully evaluated; in this article, we aim to find if COVID-19 exposure is linked to congenital anomalies. Further research is needed to ascertain neonatal outcomes.

BACKGROUND: In the present review, we aimed to synthesize evidence from studies on the safety and effectiveness of prophylactic blood transfusion in pregnant women with sickle cell disease. MATERIAL AND METHODS: To gather relevant information, we conducted systematic electronic searches of databases such as SCOPUS, Medline via PubMed, Web of Science, and Cochrane Central Register of Controlled Trials. We included both retrospective and prospective studies that examined the impact of prophylactic blood transfusions during pregnancy. The collected data were analyzed using Review Manager, version 5.3. RESULTS: The review included 15 cohort studies. The overall findings indicated a preference for the prophylactic blood transfusion group over the control group across several key parameters. Specifically, the prophylactic group demonstrated lower rates of maternal mortality (odds ratio [OR]â =â 0.33; 95% confidence interval [CI] = 0.10-1.13; Pâ =â .08), reduced incidence of vaso-occlusive painful events (ORâ =â 0.31; 95% CI = 0.14-0.73; Pâ =â .007), fewer pulmonary complications (ORâ =â 0.21; 95% CI = 0.08-0.53; Pâ =â .001), decreased perinatal mortality (ORâ =â 0.35; 95% CI = 0.17-0.75; Pâ =â .03), and lower likelihood of preterm birth (ORâ =â 0.67; 95% CI = 0.47-0.96; Pâ =â .02). Notably, statistically significant heterogeneities were observed in the pooled effect estimates. CONCLUSION: The present meta-analysis indicated that prophylactic blood transfusion in pregnant women with sickle cell disease may improve maternal and fetal outcomes. However, substantial variations in the methodology and transfusion protocols among the included studies limited the credibility of the current evidence supporting the routine clinical use of prophylactic transfusion for SCD during pregnancy.

BACKGROUND: Abortion is a public health problem in Latin America and is more common among women living with HIV. OBJECTIVE: to verify the incidence and factors associated with induced abortion in a cohort of women living with HIV assisted in a reference service for care for individuals with HIV/AIDS in Rio de Janeiro/Brazil. METHODS: Prospective cohort during the period 1996-2016. We estimated the incidence of induced abortions during follow-up in the cohort by calculating person-time incidence rates [per 100 persons-years (PY)] and investigated the factors associated with the outcome "induced abortion" using a generalized linear mixed model. RESULTS: 753 women and 210 pregnancies were included in the present analysis. We estimated an induced abortion incidence rate of 0.68/100 persons-years (95% confidence interval [CI]: 0.47; 0.94) in the study period, with a significant reduction after 2006. The main factors associated with an induced abortion were currently living with a partner (adjusted OR [AdjOR] 0.32 95% CI: 0.10-0.98), number of children (2 children AdjOR 0.12, 95% CI: 0.02-0.95) and the type of antiretroviral treatment used (regimen without Efavirenz: AdjOR: 0.11, 95% CI 0.02-0.70). CONCLUSIONS: We showed a significant reduction in the incidence of induced abortions in a cohort of women living with HIV in Rio de Janeiro, Brazil, probably due to a decrease in the incidence of pregnancies observed in the same period. The factors associated with a lower occurrence of induced abortion suggest a good integration between the clinical and reproductive assistance offered to those women.

Background: Bleeding is a serious cause of hypotension and tachycardia after childbirth and should always be considered. Case presentation: A healthy woman in her thirties who had previously undergone caesarean section, underwent induction and operative vaginal delivery. Postpartum, she experienced chest pain, hypotension and tachycardia, and had signs of ischaemia on electrocardiogram. A CT scan showed a large intraperitoneal haematoma. The patient underwent immediate laparotomy and received a massive blood transfusion. However, no large haematoma was found. The chest pain was attributed to a myocardial infarction caused by hypovolaemic shock. After discharge, the patient experienced significant vaginal bleeding and was transferred to a different university hospital. A CT scan revealed a large retroperitoneal haematoma. Emergency surgery was performed based on the suspicion of active bleeding, but only an older haematoma was found. Re-evaluation of the initial CT scan revealed that the haematoma was in fact located retroperitoneally and was thereby not found in the first operation. Interpretation: This case highlights the importance of bleeding as an important cause in unstable postpartum patients. Additionally, it is a reminder that retroperitoneal haematomas can occur in obstetric patients and can mask typical symptoms of uterine rupture such as abdominal pain. also hindering perioperative diagnosis.

BACKGROUND: On 7 October 2023, Hamas lunched a massive terror attack against Israel. The first weeks after were characterized with great uncertainty, insecurity, and fear. OBJECTIVES: To evaluate the effect of the first 2 months of the Iron Swords war on obstetrical emergency attendance and the corresponding perinatal outcomes. METHODS: We conducted a single center retrospective cohort study of all singleton births between 7 October and 7 December 2023. Prenatal emergency labor ward admission numbers and obstetric outcomes during the first 2 months of the war were compared to the combined corresponding periods for the years 2018-2022. RESULTS: During the initial 2 months of the conflict 1379 births were documented. The control group consisted of 7304 deliveries between 2018 and 2022. There was a decrease in daily emergency admissions to the labor ward during the first 5 weeks of the conflict compared to the corresponding periods in the preceding years (51.8 ± 15.0 vs. 57.0 ± 13.0, P = 0.0458). A notable increase in stillbirth rates was observed in the study group compared to the control group (5/1379 [0.36%] vs. 7/7304 [0.1%]; P = 0.014). Both groups exhibited similar gestational ages at birth, rates of preterm and post-term delivery, neonatal birthweights, mode of delivery, and induction of labor rates. CONCLUSIONS: In the initial weeks following Hamas's attack on Israel, there was a notable decrease in admissions to the prenatal emergency labor ward. This decline coincided with an increase in the rate of stillbirths among a population not directly involved in the conflict.
