Sentimentos da mulher frente a gestação de alto risco / Sentimientos de la mujer frente al embarazo de alto riesgo / Women's feelings facing High-Risk pregnancy

Resumo Introdução: A gestação configura-se como um acontecimento único e memorável para a vida de uma mulher. A gravidez de alto risco é uma experiência estressante em razão dos riscos a que estão submetidos a mãe e o bebê e devido às mudanças que afetam negativamente o seu equilíbrio emocional. Objetivo: Identificar os sentimentos vivenciados pela gestante frente à gravidez de alto risco. Método: Descritivo e exploratório com abordagem qualitativa, com amostra por conveniência composta por mulheres com gestação de alto risco, selecionadas de acordo com a disponibilidade do serviço de internamento, até a saturação das entrevistas. A coleta dos dados foi realizada em um período de dois meses através de entrevistas guiadas por um roteiro. Os dados foram analisados por meio da técnica de análise de conteúdo segundo Minayo. Resultados: Fizeram parte 37 mulheres. Os resultados foram oeganizados nas categorias: Como se deu o diagnóstico de alto risco; Sentimentos ao descobrir que a gestação é/era de risco; Sentimentos em relação ao apoio familiar acerca da gestação de alto risco. Os sentimentos relatados pelas gestantes e puérperas que conviveram com a gravidez de alto risco, deixam evidentes os impactos que este evento traz não somente na saúde física sobretudo para a emocional, deixando as gestantes fragilizadas. Conclusão: Assim, o estudo nos permitiu perceber que os sentimentos vivenciados nesse processo podem interfir na vida dessas mulheres, e de forma negativa. Mas, que apesar dessa situação, estas expressam sentimentos ambíguos, pois mesmo com o risco gestacional, muitas mostram-se felizes pela dádiva de ser mãe.

Resumen Introducción: El embarazo se considera un evento único y memorable en la vida de una mujer. El embarazo de alto riesgo es una experiencia estresante debido a los riesgos a los que están expuestas tanto la madre como su bebé y a los cambios que afectan negativamente su equilibrio emocional. Objetivo: Identificar los sentimientos experimentados por las mujeres embarazadas frente a un embarazo de alto riesgo. Metodología: Descriptivo y exploratorio con enfoque cualitativo, con una muestra a conveniencia compuesta por mujeres con embarazos de alto riesgo, seleccionadas según la disponibilidad del servicio de hospitalización, hasta la saturación de las entrevistas. La recopilación de datos se llevó a cabo durante un período de dos meses a través de entrevistas guiadas. Los datos fueron analizados utilizando la técnica de análisis de contenido según Minayo. Resultados: Participaron 37 mujeres y los resultados se organizaron en las siguientes categorías: cómo se realizó el diagnóstico de alto riesgo; sentimientos al descubrir que el embarazo era de riesgo; sentimientos con respecto al apoyo familiar en relación con el embarazo de alto riesgo. Los sentimientos relatados por las mujeres embarazadas y posparto que vivieron un embarazo de alto riesgo evidencian los impactos que tiene este evento no solo en la salud física sino, especialmente, en el bienestar emocional, pues deja a las mujeres embarazadas en un estado de vulnerabilidad. Conclusión: El estudio nos permitió darnos cuenta de que los sentimientos experimentados en este proceso pueden interferir en la vida de estas mujeres de manera negativa. Sin embargo, a pesar de esta situación, muchas de ellas expresan sentimientos ambiguos, porque, incluso con el riesgo gestacional, están agradecidas por el regalo de la maternidad.

Abstract Introduction: Pregnancy is considered a unique and memorable event in a woman's life. High-risk pregnancy is a stressful experience due to the risks to which the mother and the baby are exposed, and due to the changes that negatively affect their emotional balance. Objective: To identify the feelings experienced by pregnant women facing high-risk pregnancy. Method: Descriptive and exploratory, employing a qualitative approach, the study featured a convenience sample of women with high-risk pregnancies, selected based on inpatient service availability, until interview saturation was achieved. Data collection was conducted over a two-month period through scripted interviews. Data analysis was performed utilizing Minayo's content analysis technique. Results: Thirty-seven women participated in the study. The results were categorized as follows: How the high-risk diagnosis was determined; Feelings upon discovering the pregnancy was high-risk; Feelings regarding family support regarding the high-risk pregnancy. The feelings reported by pregnant and postpartum women who experienced high-risk pregnancies clearly reveal the impacts this event has, not only on physical health, but especially on emotional well-being, leaving the pregnant women in a vulnerable state. Conclusion: The study allowed us to realize that the feelings experienced in this process can negatively interfere in the lives of these women. However, despite this situation, many of them express mixed feelings, because even with the gestational risk, they are grateful for the gift of motherhood.

The prevalence of suicidal behavior and ideation during pregnancy and postpartum period, its variation in the COVID-19 pandemic, and the related factors: A systematic review and meta-analysis of observational studies

Bacground Pregnancy and postpartum are sensitive periods for mental health problems due to increased stressors and demands, and the prevalence of intentional self-harming behaviors such as suicidal behavior and ideation may increase. Changes in the provision of prenatal care services and utilization of health services and adverse living conditions during the COVID-19 epidemic may also trigger or exacerbate mental illnesses. Aims To investigate the prevalence of suicidal behavior and ideation encountered during pregnancy and postpartum period, its change in the COVID-19 pandemic, and the related factors. Methods A systematic review and meta-analysis of observational studies was conducted. A search was conducted in April 2021 and updated in April 2023 on Web of Science, PubMed, PsycINFO, EBSCO, Turk Medline, Turkish Clinics, and ULAKBIM databases. Two authors independently conducted the search, selection of articles, data extraction, and quality assessment procedures, and an experienced researcher controlled all these steps. Joanna Briggs Institute's Critical Appraisal Checklists were used to assess the quality of the studies. Results The meta-analysis included 38 studies and the total sample size of the studies was 9 044 991. In this meta-analysis, the prevalence of suicidal behavior in women during pregnancy and postpartum periods was 5.1 % (95 % CI, 0.01–1.53), suicidal ideation 7.2 % (95 % CI, 0.03–0.18), suicide attampt 1 % (95 % CI, 0.00–0.07) and suicidal plan 7.8 % (95 % CI, 0.06–0.11). Rate of suicidal behavior, ideation/thought increased and attempts in the pandemic process (2.5% vs 19.7 %; 6.3% vs 11.3 %; 3.6% vs 1.4 %, respectively). Prevalences of suicidal behavior, ideation, attempts, and plan in the postpartum period was higher than during pregnancy (1.1% vs 23.4 %; 6.1% vs 9.2 %; 0.5% vs 0.7 %; 7.5% vs 8.8 %, respectively). ...

Hypertensive states of pregnancyEstados hipertensivos del embarazo / Estados hipertensivos del embarazo

Hypertensive disorders in pregnancy (HDP) remain a leading cause of pregnancy-related maternal and foetal morbidity and mortality worldwide, including chronic hypertension, gestational hypertension, and pre-eclampsia. Affected women and newborns also have an increased risk of cardiovascular disease later in life, independent of traditional cardiovascular disease risks. Despite these risks, recommendations for optimal diagnosis and treatment have changed little in recent decades, probably due to fear of the foetal repercussions of decreased blood pressure and possible drug toxicity. In this document we review the diagnostic criteria and classification of (HDP), as well as important aspects regarding pathophysiology and early detection that allows early identification of women at risk, with the aim of preventing both immediate and long-term consequences. Prophylactic treatment with aspirin is also reviewed early and a therapeutic approach is carried out that involves close maternal and foetal monitoring, and if necessary, the use of safe drugs in each situation. This review aims to provide an updated vision for the prevention, diagnosis, and treatment of HDP that is useful in our usual clinical practice.(AU)

Los estados hipertensivos del embarazo (EHE) siguen siendo una de las principales causas de morbilidad y mortalidad materna y fetal relacionada con el embarazo en todo el mundo, incluyen la hipertensión crónica, la hipertensión gestacional y la preeclampsia. Las mujeres afectadas y los recién nacidos también tienen un mayor riesgo de sufrir enfermedades cardiovasculares en el futuro, independientemente de los riesgos tradicionales de la enfermedad cardiovascular. A pesar de estos riesgos, las recomendaciones para un diagnóstico y un tratamiento óptimo han cambiado poco en las últimas décadas, probablemente por el miedo a las repercusiones fetales de la disminución de la presión arterial y la posible toxicidad farmacológica. En ese documento revisamos los criterios diagnósticos y la clasificación de los EHE, así como aspectos importantes en cuanto a fisiopatología y la detección temprana que permita la identificación precoz de las mujeres en riesgo, con el objetivo de prevenir tanto las secuelas inmediatas como a largo plazo. También se revisa el tratamiento profiláctico con aspirina de forma precoz y se realiza una aproximación terapéutica que implica una estrecha vigilancia materna y fetal, y si es necesario, el uso de fármacos seguros en cada situación. Esta revisión pretende dar una visión actualizada para la prevención, diagnóstico y tratamiento de los EHE que sea de utilidad en nuestra práctica clínica habitual.(AU)

Epidemiology of an overlapping and parallel infection of Sexually Transmitted Infections among pregnant women in North-east Ethiopia: Its implication for prevention of mother to child transmission.

BACKGROUND: The burden of parallel and overlapping infections of Sexually Transmitted Infections (STIs), particularly HIV, syphilis, hepatitis B (HBV), and hepatitis C virus (HCV) are disproportionately higher among pregnant women globally, leading to unwanted consequences. These infections pose significant public health challenges as they can be transmitted vertically to the offspring. This study aimed to determine the sero-epidemiological patterns and predictors of STIs (HIV, syphilis, HBV, and HCV) among pregnant women attending antenatal care clinics at ten health facilities in North-eastern Ethiopia. METHODS: An institution-based multi-center cross-sectional study was conducted from May to November 2022 among 422 pregnant women selected using simple random sampling technique. Semi-structured questionnaire was used to collect socio-demographic characteristics and predictor variables of STIs through face-to-face interviews. Venous blood was collected and it was tested for anti-HIV, HBsAg, anti-HCV, and anti-Treponemal antibodies using immunochromatographic test kits. Multinomial logistic regression analysis was used to identify associated factors of STIs. Variables with an adjusted odds ratio (AOR) and a p-value <0.05 were considered statistically significant. RESULTS: The overall prevalence of STIs was 23.9% (95% CI = 20.08-28.25). The prevalence of parallel infections of HIV, hepatitis B, hepatitis C, and syphilis were 6.4%, 9%, 1.7%, and 6.9%, respectively. The overlapping infections for HIV-HBV was 4% but HIV-HCV overlapping infection wasn't found. Increased age, tattooing, multiple sexual partners, exposure to unsafe sex, and RH status were independent factors of HBV. Likewise, increased age, rural residence, illiteracy, and tattooing were independently associated with HCV. Moreover, rural residence and a history of tattooing were independent predictors for the acquisition of HIV, whereas multiple sexual partners and RH status were found to be significant predictors of syphilis infection among pregnant women. CONCLUSION: The magnitude of overlapping and parallel STD infections is still continued to be a problem among pregnant women. Moreover, there were overlapping infections of HBV-HIV. Therefore, continuous screening of pregnant women for HIV, syphilis, hepatitis B, and C infections should be performed, and special attention should be given to pregnant women who have co-infections.

Perinatal mortality after Chornobyl in contaminated regions of Ukraine.

BACKGROUND: Belarus and Ukraine were the countries most affected by the consequences of the Chornobyl nuclear power plant in 1986. A study of perinatal mortality in Belarus found a highly statistically significant increase in the 1990s in the most contaminated oblast Gomel but no increase during this period in the rest of Belarus. As a possible mechanism to interpret this increase as a late Chornobyl effect, it has been suggested that strontium-90 contained in Chornobyl fallout, incorporated during menarche, impairs the immune system of pregnant women which in turn increases perinatal mortality. In the present study, this hypothesis is tested using data from Ukraine. METHODS: Annual data on perinatal mortality, in the period 1981-2006 were provided by the Ministry of Public Health of Ukraine. Trends in perinatal mortality rates in the most contaminated regions of Ukraine (Kyiv and Zhytomyr oblasts and the city of Kyiv; study region) were compared with rates in the rest of Ukraine (control region). To identify any differences in perinatal mortality trends between the study and control regions, the ratios of perinatal mortality rates in the study region to the rates in the control region were analyzed using the calculated strontium concentration as a predictor. RESULTS: A trend analysis of perinatal mortality rates in Ukraine revealed two bell-shaped deviations from a long-term exponential trend with maxima at the beginning and end of the 1990s. The same pattern was found in the data from the study and control regions, but the deviations were almost three times higher in the study region than in the control region. An analysis of the ratios of perinatal mortality rates in the study region to the rates in the control region (odds ratios) showed an increase and decrease during the 1990s which was approximated by a lognormal density distribution. The calculated strontium concentration, when used as a predictor, also fitted the data well. Thus, the data from Ukraine confirms the results from Belarus. The analysis of the odds ratios revealed about 1000 excess perinatal deaths in the study region in the period 1990-2004. The corresponding figure for Ukraine as a whole was estimated at 3500 perinatal deaths. CONCLUSION: It is hypothesized that the observed increase in perinatal mortality in the 1990s may be a late effect of incorporated strontium-90 on the immune system of pregnant women. The analysis is based on a theoretical model, as no data on strontium concentrations were available; the results should therefore be interpreted with caution. An updated study for Belarus would be desirable to corroborate the results.

Validating the indicator "maternal death review coverage" to improve maternal mortality data: A retrospective analysis of district, facility, and individual medical record data.

BACKGROUND: Understanding causes and contributors to maternal mortality is critical from a quality improvement perspective to inform decision making and monitor progress toward ending preventable maternal mortality. The indicator "maternal death review coverage" is defined as the percentage of maternal deaths occurring in a facility that are audited. Both the numerator and denominator of this indicator are subject to misclassification errors, underreporting, and bias. This study assessed the validity of the indicator by examining both its numerator-the number and quality of death reviews-and denominator-the number of facility-based maternal deaths and comparing estimates of the indicator obtained from facility- versus district-level data. METHODS AND FINDINGS: We collected data on the number of maternal deaths and content of death reviews from all health facilities serving as birthing sites in 12 districts in three countries: Argentina, Ghana, and India. Additional data were extracted from health management information systems on the number and dates of maternal deaths and maternal death reviews reported from health facilities to the district-level. We tabulated the percentage of facility deaths with evidence of a review, the percentage of reviews that met the World Health Organization defined standard for maternal and perinatal death surveillance and response. Results were stratified by sociodemographic characteristics of women and facility location and type. We compared these estimates to that obtained using district-level data. and looked at evidence of the review at the district/provincial level. Study teams reviewed facility records at 34 facilities in Argentina, 51 facilities in Ghana, and 282 facilities in India. In total, we found 17 deaths in Argentina, 14 deaths in Ghana, and 58 deaths in India evidenced at facilities. Overall, >80% of deaths had evidence of a review at facilities. In India, a much lower percentage of deaths occurring at secondary-level facilities (61.1%) had evidence of a review compared to deaths in tertiary-level facilities (92.1%). In all three countries, only about half of deaths in each country had complete reviews: 58.8% (n = 10) in Argentina, 57.2% (n = 8) in Ghana, and 41.1% (n = 24) in India. Dramatic reductions in indicator value were seen in several subnational geographic areas, including Gonda and Meerut in India and Sunyani in Ghana. For example, in Gonda only three of the 18 reviews conducted at facilities met the definitional standard (16.7%), which caused the value of the indicator to decrease from 81.8% to 13.6%. Stratification by women's sociodemographic factors suggested systematic differences in completeness of reviews by women's age, place of residence, and timing of death. CONCLUSIONS: Our study assessed the validity of an important indicator for ending preventable deaths: the coverage of reviews of maternal deaths occurring in facilities in three study settings. We found discrepancies in deaths recorded at facilities and those reported to districts from facilities. Further, few maternal death reviews met global quality standards for completeness. The value of the calculated indicator masked inaccuracies in counts of both deaths and reviews and gave no indication of completeness, thus undermining the ultimate utility of the measure in achieving an accurate measure of coverage.

Associations between child marriage and reproductive and maternal health outcomes among young married women in Liberia and Sierra Leone: A cross-sectional study.

BACKGROUND: Child marriage has been associated with a range of negative maternal and reproductive health outcomes. This study explored these associations in Liberia and Sierra Leone and examined how child marriage intersected with other measures of social disadvantage. METHODS: Data were derived from 631 and 1,325 married or cohabitating women aged 20-24 interviewed in the 2019-2020 Liberia and 2019 Sierra Leone Demographic and Health Surveys, respectively. Analyses were stratified by country. Regression models examined associations between age at first marriage (<15, 15-17, and 18+ years) and reproductive and maternal health outcomes, as well as interactions between child marriage and measures of social disadvantage. Multivariable regression results were presented as adjusted odds ratios and 95% confidence intervals. RESULTS: Over half of currently married/cohabitating women aged 20-24 in Liberia (52%) and Sierra Leone (54%) married before age 18, and over one in 10 married before age 15. In both countries, after adjusting for other factors, being married before the age of 18 was significantly associated with early fertility, high fertility, and low fertility control. Associations were particularly strong among women who first married before age 15. In Liberia, women who married at age 15-17 had significantly lower odds of skilled attendance at delivery and institutional delivery if they lived in the North Central region. Sierra Leonean women who married before age 15 had lower odds of institutional delivery and lower odds of four or more ANC visits if they lived in the North Western region. CONCLUSION: This study found clear associations between child marriage and negative reproductive health outcomes in Liberia and Sierra Leone, with stronger associations among women married in early adolescence. Child marriage and region of residence intersected to shape young women's access to skilled attendance at birth and institutional delivery. These findings call for further investigation and targeted intervention.

Effect of feeding sodium butyrate to beef female cows during pre- and post-partum period on concentrations of glucagon-like peptides in plasma and colostrum.

The objective of this study was to evaluate the effect of feeding beef cows with sodium butyrate during the late pregnancy and early post-partum periods on concentrations of glucagon-like peptide (GLP)-1 and 2 in plasma, colostrum, and transition milk. Twelve Japanese Black female cows were fed concentrate feed without (CON; n = 6) or with (BUTY; n = 6) sodium butyrate supplementation at 1.1% of dietary dry matter from -60 d relative to the expected parturition date to 4 d after parturition. Plasma total cholesterol concentration was higher for the BUTY than for the CON (P = 0.04). In addition, plasma GLP-1 concentration was higher for the BUTY than for the CON at 3 d after calving (P < 0.05). This study showed for the first time that GLP-1 is present in the colostrum of Japanese Black cows at higher concentrations as compared to in plasma (P < 0.01). On the other hand, no treatment effect was observed for concentrations of metabolite and hormone in colostrum and transition milk. In summary, feeding beef cows with sodium butyrate during the late gestation and early post-partum period likely increases plasma GLP-1 concentrations post-partum without affecting the components of colostrum and transition milk.

United Kingdom Data Deficiencies Influencing U.S. FDA Decisions.

The U.S. FDA has permanently removed the in-person prescribing requirements that previously safeguarded the use of mifepristone/misoprostol medical abortions, allowing prescribing through telemedicine or on-line ordering and distribution through the mail and pharmacies, without standard pre-abortion testing. This will increase the risk of complications due to failure to adequately determine the gestational age or rule out ectopic pregnancy by ultrasound or physical exam, failure to perform labs to document whether RhoGAM is indicated, and failure to obtain appropriate informed consent to prevent unwanted abortions, among other concerns. The FDA justified this action by referencing flawed studies with significantly undercounted complications. The details of these study deficiencies are examined in this paper.

In Vitro Fertilization, State Wrongful Death Statutes and State Fetal Homicide Statutes: The Reaction to LePage v. Center for Reproductive Medicine.

The Alabama Supreme Court recently held, in LePage v. Center for Reproductive Medicine, that the parents of human embryos that were negligently destroyed at a fertility clinic could bring an action for damages under the State's wrongful death statute. Although the Alabama legislature promptly enacted a law essentially overturning the state supreme court's decision, concerns have been raised that the court's decision might influence courts in other States to interpret their wrongful death statutes, or possibly even their fetal homicide statutes, to apply in similar circumstances, thereby threatening the availability of in vitro fertilization (IVF) technology. This article addresses those concerns.With respect to wrongful death statutes, only fourteen States (excluding Alabama) have interpreted their statutes to apply to unborn children without regard to their stage of gestation or development. The majority of States impose a gestational requirement (typically, viability) which would preclude their application to the destruction of human embryos. Even with respect to the minority of States that impose no limitation on the cause of action, those statutes, either by their express language or by fair interpretation, would not apply to unimplanted human embryos.With respect to the fetal homicide statutes in thirty-one States that do not have any gestational or developmental limitation, the statutes in twenty-six of those States apply only to acts causing the death of an unborn child in utero. As to the statutes in the other five States, the structure of the statute, considered in light of the applicable case law, strongly suggests that there would be no liability for causing the death of an unborn child before implantation. In sum, the Alabama Supreme Court's decision in LePage is not likely to be followed as a precedent in interpreting either the wrongful death statutes or the fetal homicide statutes of any other State.

A Reanalysis of Mental Disorders Risk Following First-Trimester Abortions in Denmark.

Background: A previous Danish study of monthly and tri-monthly rates of first-time psychiatric contact following first induced abortions reported higher rates compared to first live births but similar rates compared to nine months pre-abortion. Therefore, the researchers concluded abortion has no independent effect on mental health; any differences between psychiatric contacts after abortion and delivery are entirely attributable to pre-existing mental health differences. However, these conclusions are inconsistent with similar studies that used longer time frames. Reanalysis of the published Danish data over slightly longer time frames may reconcile this discordance. Method: Monthly and tri-monthly data was extracted for reanalysis of cumulative effects over nine- and twelvemonths post-abortion. Results: Across all psychiatric diagnoses, cumulative average monthly rate of first-time psychiatric contact increased from an odds ratio of 1.12 (95% CI: 1.02 to 1.22) at 9-months to 1.49 (95% CI: 1.37 to 1.63) at 12 months post-abortion as compared to the 9 months pre-abortion rate. At 12 months post-abortion, first-time psychiatric contact was higher across all four diagnostic groupings and highest for personality or behavioral disorders (OR=1.87; 95% CI:1.48 to 2.36) and neurotic, stress related, or somatoform disorders (OR=1.60; 95% CI: 1.41 to 1.81). Conclusions: Our reanalysis revealed that the Danish data is consistent with the larger body of both record-based and survey- based studies when viewed over periods of observation of at least nine months. Longer periods of observation are necessary to capture both anniversary reactions and the exhaustion of coping mechanisms which may delay observation of post-abortion effects.

Misleading Statements About "Life of the Mother" Exceptions in Pro-life Laws Require Correction.

Misleading statements in a recent Obstetrics & Gynecology article require correction. No state has an abortion law that is a total ban on abortion. Every state law permits abortion when necessary to save a mother's life. Texas law does not require an "imminent" risk and allows a doctor to use his "reasonable medical judgment" to determine if an abortion is necessary to prevent a "risk" of maternal death. Similarly, Idaho allows a doctor to use his "good faith medical judgment" to determine when to intervene, without need for "immediacy".

Acute peripartum pancreatitis complicating seronegative antiphospholipid antibody syndrome in pregnancy.

Antiphospholipid antibody syndrome is an autoimmune condition with clinical manifestations of vascular thrombosis and adverse pregnancy outcomes including recurrent miscarriage, fetal loss, growth restriction and pre-eclampsia with persistent antiphospholipid antibodies on laboratory examination. Treatment is targeted at preventing recurrent thrombosis and improving pregnancy outcomes. Commonly, treatment includes aspirin and anticoagulation, however, newer immunomodulatory treatments may also improve outcomes. The case describes a patient with a history of multiple miscarriages and pregnancy losses, fetal growth restriction and pre-eclampsia, and pulmonary embolism. Because of her significant adverse pregnancy outcomes, she was treated with certolizumab with a successful delivery at 33 weeks and 6 days. She also developed acute pancreatitis in the postpartum period. This is a rare condition, affecting 1-14/10 000 births. The pancreatitis resolved with conservative management, and she had an uncomplicated interval cholecystectomy.

Childhood atopic disorders in relation to placental changes-A systematic review and meta-analysis.

Fetal programming may arise from prenatal exposure and increase the risk of diseases later in life, potentially mediated by the placenta. The objective of this systematic review was to summarize and critically evaluate publications describing associations between human placental changes and risk of atopic disorders during childhood. The review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. The inclusion criteria were original research articles or case reports written in English describing a human placental change in relation to disease occurring in offspring during childhood. The MEDLINE and EMBASE databases were searched for eligible studies. Risk of bias (RoB) was assessed using the ROBINS-I tool. The results were pooled both in a narrative way and by a meta-analysis. Nineteen studies were included (n = 12,997 participants). All studies had an overall serious RoB, and publication bias could not be completely ruled out. However, five studies showed that histological chorioamnionitis in preterm-born children was associated with asthma-related problems (pooled odds ratio = 3.25 (95% confidence interval = 2.22-4.75)). In term-born children, a large placenta (≥750 g) increased the risk of being prescribed anti-asthma medications during the first year of life. Placental histone acetylation, DNA methylation, and gene expression differences were found to be associated with different atopic disorders in term-born children. There is some evidence supporting the idea that the placenta can mediate an increased risk of atopic disorders in children. However, further studies are needed to validate the findings, properly control for confounders, and examine potential mechanisms.

Maternal birth weight is an indicator of preterm delivery: the Japan environment and children's study.

This study aimed to investigate the association between maternal birth weight (MBW) with preterm delivery (PTD) in the Japanese population. To this end, a total of 78,972 Japanese pregnant women were included in a prospective birth cohort study. Multiple logistic regression and multinominal logistic regression models were applied to investigate the associations of MBW with PTD (delivery from 22 to < 37 weeks of gestation), early PTD (delivery from 22 to < 34 weeks), and late PTD (delivery from 34 to < 37 weeks). The results showed that MBW was inversely associated with PTD, early PTD, and late PTD (p-for-trend < 0.0001, 0.0014, and < 0.0001, respectively). The adjusted odds ratios per each 500 g of MBW decrease were 1.167 (95% confidence interval [CI]: 1.118-1.218) for PTD, 1.174 (95% CI: 1.070-1.287) for early PTD and 1.151 (95% CI: 1.098-1.206) for late PTD. The effect size of the association of MBW with early PTD was similar to that with late PTD. This study demonstrated for the first time an association of a low MBW with PTD, early PTD, and late PTD in a Japanese nationwide cohort.

The impact of caesarean scar niche on fertility - a systematic review.

BACKGROUND: The trend of increasing caesarean section (CS) rates brings up questions related to subfertility. Research regarding the influence of CS on assisted reproduction techniques (ART) is conflicting. A potential mechanism behind CS-induced subfertility is intra uterine fluid resulting from a caesarean scar defect or niche. The vaginal microbiome has been repeatedly connected to negative ART outcomes, but it is unknown if the microbiome is changed in relation to a niche. METHODS: This systematic review describes literature investigating the effect of a niche on live birth rates after assisted reproduction. Furthermore, studies investigating a difference in microbial composition in subfertile persons with a niche compared to no niche are evaluated. Pubmed, Embase and Web of Science were searched on March 2023 for comparative studies on both study questions. Inclusion criteria were i.e., English language, human-only studies, availability of the full article and presence of comparative pregnancy data on a niche. The quality of the included studies and their risk of bias were assessed using the Newcastle-Ottawa scale for cohort studies. The results were graphically displayed in a forest plot. RESULTS: Six retrospective cohort studies could be included on fertility outcomes, with a total of 1083 persons with a niche and 3987 without a niche. The overall direction of effect shows a negative impact of a niche on the live birth rate (pooled aOR 0.58, 95% CI 0.48-0.69) with low-grade evidence. Three studies comparing the microbiome between persons with and without a CS could be identified. CONCLUSION: There is low-grade evidence to conclude that the presence of a niche reduces live birth rates when compared to persons without a niche. The theory that a caesarean has a negative impact on pregnancy outcomes because of dysbiosis promoted by the niche is interesting, but there is no sufficient literature about this.

The increasing number of caesarean deliveries has raised concerns about how it might affect a woman's ability to get pregnant afterwards. Some studies suggest that having a caesarean section (CS) could make it harder to conceive, particularly through in vitro fertilisation (IVF). The reason could be the scar or niche from a previous caesarean. This niche can cause fluid inside the uterus. We also know that the mix of bacteria in the vagina, called the vaginal microbiome, can affect a woman's chances of getting pregnant, especially with treatments like IVF. But we are not sure if having a caesarean affects the vaginal microbiome.To understand this better, van den Tweel's team looked at studies on whether having a niche from a caesarean affects a woman's chance of having a baby through IVF. They also looked at studies comparing the bacteria in the vagina of women who have had a caesarean with those who have not. They found that having a caesarean niche makes it harder for a woman to have a baby through IVF. However, the evidence from these studies is not very strong. We still do not know enough about whether having a caesarean niche affects the bacteria in the vagina.

The effect of coenzyme Q10 on cryotolerance of in vivo-derived mouse embryos.

OBJECTIVE: Cryopreservation has some adverse effects on embryos including cell metabolism reduction, mitochondria and plasma membrane damage, excess production of 'Reactive Oxygen Species' and damage to DNA. In the present study. In this study we assessed the effect of coenzyme Q10 as an exogenous antioxidant on mouse embryos following cryopreservation. METHODS: We collected mice embryos at the morula stage from uterine horns on the third day of gestation. The morulae were divided into 9 groups (1 control, 2 vehicles and 6 experimental), then vitrified. The culture and/or vitrification media of the experimental groups were supplemented by 10 or 30 µM of CoQ10. After one week, the embryos were warmed and then cultured. After 48 hours of embryo culture, the blastocyst rate, total cell number, viability; and after 72 hours of embryo culture, we assessed the hatching rate. RESULTS: Blastocyst rate and hatching rate were significantly reduced in the groups containing 30 µM CoQ10 supplemented culture media compared to other groups (p<0.05). The hatching rate in the groups containing 10 µM CoQ10 supplemented in both culture and vitrification media was significantly higher than in the other groups (p<0.05). In groups containing 10 µM CoQ10 supplemented culture media, the viability was higher than that in the other groups (p<0.05). CONCLUSIONS: It seems that CoQ10 in a dose-dependent manner is able to improve hatching rate and viability following cryopreservation through its antioxidant and anti-apoptotic properties, and through the production of ATP.

The impact of pubertal stress and adult hormone exposure on the transcriptome of the developing hypothalamus.

Why individuals suffer negative consequences following stress is a complex phenomenon that is dictated by individual factors, the timing of stress within the lifespan, and when in the lifespan the consequences are measured. Women who undergo adverse childhood experiences are at risk for lasting biological consequences, including affective and stress dysregulation. We have shown that pubertal adversity is associated with a blunted hypothalamic-pituitary-adrenal axis glucocorticoid response in peripartum humans and mice. In mice, our prior examination of the paraventricular nucleus (PVN) of the hypothalamus showed that pubertal stress led to an upregulation of baseline mRNA expression of six immediate early genes (IEGs) in the PVN of adult, pregnant mice. Separately, we showed that the pregnancy-associated hormone allopregnanolone is necessary and sufficient to produce the blunted stress response phenotype in pubertally stressed mice. In the current study, we further examined a potential mechanistic role for the IEGs in the PVN. We found that in pubertally stressed adult female, but not male, mice, intra-PVN allopregnanolone was sufficient to recapitulate the baseline IEG mRNA expression profile previously observed in pubertally stressed, pregnant mice. We also examined baseline IEG mRNA expression during adolescence, where we found that IEGs have developmental trajectories that showed sex-specific disruption by pubertal stress. Altogether, these data establish that IEGs may act as a key molecular switch involved in increased vulnerability to negative outcomes in adult, pubertally stressed animals. How the factors that produce vulnerability combine throughout the lifespan is key to our understanding of the etiology of stress-related disorders.
