RESUMEN
The early-life gut microbiome is linked to human phenotypes as an imbalanced microbiome of this period is implicated in diseases throughout life. Several determinants of early-life gut microbiome are explored, however, mechanisms of acquisition, colonization, and stability of early-life gut microbiome and their interindividual variability remain elusive. Host genetics play a vital role to shape the gut microbiome and interact with it to modulate individual phenotypes in human studies and animal models. Given the microbial linkage between host generations, we discuss the current state of roles of host genetics in forming intergenerational microbiomes associated with mothers, offspring, and those vertically transmitted, providing a basis for taking into account host genetics in future early-life microbiome research. We further expand our discussion to the bidirectional interactions between host gene expression and microbiome in human health.

BACKGROUND: Placental heart development and embryonic heart development occur in parallel, and these organs have been proposed to exert reciprocal regulation during gestation. Poor placentation has been associated with congenital heart disease, an important cause of infant mortality. However, the mechanisms by which altered placental development can lead to congenital heart disease remain unresolved. METHODS: In this study, we use an in vivo neutrophil-driven placental inflammation model through antibody depletion of maternal circulating neutrophils at key stages during time-mated murine pregnancy: embryonic days 4.5 and 7.5. Pregnant mice were culled at embryonic day 14.5 to assess placental and embryonic heart development. A combination of flow cytometry, histology, and bulk RNA sequencing was used to assess placental immune cell composition and tissue architecture. We also used flow cytometry and single-cell sequencing to assess embryonic cardiac immune cells at embryonic day 14.5 and histology and gene analyses to investigate embryonic heart structure and development. In some cases, offspring were culled at postnatal days 5 and 28 to assess any postnatal cardiac changes in immune cells, structure, and cardiac function, as measured by echocardiography. RESULTS: In the present study, we show that neutrophil-driven placental inflammation leads to inadequate placental development and loss of barrier function. Consequently, placental inflammatory monocytes of maternal origin become capable of migration to the embryonic heart and alter the normal composition of resident cardiac macrophages and cardiac tissue structure. This cardiac impairment continues into postnatal life, hindering normal tissue architecture and function. Last, we show that tempering placental inflammation can prevent this fetal cardiac defect and is sufficient to promote normal cardiac function in postnatal life. CONCLUSIONS: Taken together, these observations provide a mechanistic paradigm whereby neutrophil-driven inflammation in pregnancy can preclude normal embryonic heart development as a direct consequence of poor placental development, which has major implications on cardiac function into adult life.

BACKGROUND: In select patients, pancreatic adenocarcinoma remains a local disease, yet there are no validated biomarkers to predict this behavior and who may benefit from aggressive local treatments. This study sought to determine if SMAD4 (mothers against decapentaplegic homolog 4) messenger RNA-sequencing (RNA-seq) expression is a robust method for predicting overall survival (OS) and distant metastasis-free survival (DMFS) in patients with resected pancreatic adenocarcinoma. METHODS: Utilizing The Cancer Genome Atlas (TCGA) and the International Cancer Genome Consortium (ICGC), 322 patients with resected stage I-III pancreatic adenocarcinoma were identified. In TCGA, multivariable proportional hazards models were used to determine the association of SMAD4 genomic aberrations and RNA-seq expression with OS and DMFS. In the ICGC, analysis sought to confirm the predictive performance of RNA-seq via multivariable models and receiver operator characteristic curves. RESULTS: In TCGA, the presence of SMAD4 genomic aberrations was associated with worse OS (hazard ratio [HR], 1.55; 95% CI, 1.00-2.40; p = .048) but not DMFS (HR, 1.33; 95% CI, .87-2.03; p = .19). Low SMAD4 RNA-seq expression was associated with worse OS (HR, 1.83; 95% CI, 1.17-2.86; p = .008) and DMFS (HR, 1.70; 95% CI, 1.14-2.54; p = .009). In the ICGC, increased SMAD4 RNA-seq expression correlated with improved OS (area under the curve [AUC], .92; 95% CI, .86-.94) and DMFS (AUC, .84; 95% CI, .82-.87). CONCLUSIONS: In patients with resected pancreatic adenocarcinoma, SMAD4 genomic aberrations are associated with worse OS but do not predict for DMFS. Increased SMAD4 RNA-seq expression is associated with improved OS and DMFS in patients with resected pancreatic adenocarcinoma. This reproducible finding suggests SMAD4 RNA-seq expression may be a useful marker to predict metastatic spread.

BACKGROUND: Mothers play a crucial role in influencing their daughters' HPV vaccination decisions. Addressing barriers to receiving HPV vaccination among mothers of girls may achieve two goals in one strike: increasing vaccination coverage among both mothers and their daughters. This study aims to examine the HPV vaccination uptake and its determinants among mothers of girls in China at both the individual and interpersonal levels. METHODS: From July to October 2023, a cross-sectional online study was conducted to investigate HPV vaccine refusal for daughters aged 9-17 years among 11,678 mothers in Shenzhen, China. A randomized selection method was employed, targeting 11 primary schools and 13 secondary schools in Shenzhen. The research team invited mothers of girls to participate in an anonymous online survey. Multilevel logistic regression models (level 1: schools; level 2: individual participants) were employed to analyze the data. RESULTS: Among 11,678 mothers, 41.1% self-reported receiving at least one dose of HPV vaccination. Through multilevel logistic regression analysis, eight items measuring illness representations of HPV, which refers to how people think about HPV, were associated with higher HPV vaccination uptake (AOR: 1.02-1.14). These items included identity (identifying symptoms of HPV), timeline (whether HPV is acute/chronic), negative consequences, personal and treatment control (whether HPV is under volitional control), concern, negative emotions, and coherence (overall understanding of HPV). In addition, participants refusing HPV vaccines for the index daughters (AOR: 0.82, 95%CI: 0.76, 0.89) had lower vaccine uptake. Perceived more difficulties in accessing the 9-valent vaccines (AOR: 1.06, 95%CI: 1.04, 1.08) and more satisfaction with vaccine-related promotional materials (AOR: 1.50, 95%CI: 1.46, 1.54) at the individual level were associated with higher vaccine uptake. At the interpersonal factors, higher frequency of exposure to testimonials given by others about HPV vaccination on social media (AOR: 1.19, 95%CI: 1.14, 1.25) and thoughtful consideration of the veracity of the information (AOR: 1.11, 95%CI: 1.07, 1.16) were correlated with higher HPV vaccination uptake. CONCLUSIONS: These findings offer essential implications for modifying HPV disease perceptions, addressing difficulties in accessing the 9-valent HPV vaccines, and enhancing health communication needs to improve HPV vaccine uptake among mothers of girls.

OBJECTIVES: The prevention of mother-to-child transmission of HIV has been a global success. But little is known about the growth parameters of infants delivered by mothers with HIV or the drug resistance of infants with HIV in China. The study aimed to assess growth parameters and drug resistance in Chinese infants exposed to HIV. METHODS: We conducted an 18-month longitudinal follow-up study of 3283 infants (3222 without HIV; 61 with HIV) born to mothers with HIV in the Guangxi Zhuang Autonomous Region between January 2015 and December 2021. The weight and length of all participants was recorded. In addition, genetic subtypes and drug resistance analysis were performed for infants with HIV. RESULTS: Compared with infants without HIV, those with HIV had significantly lower weight/length Z-scores, except at 18 months of age. The length/age Z-scores of infants with HIV was significantly reduced, except at 1 month of age. The weight/age Z-scores of infants with HIV were significantly lower at all follow-up time points. The weight/length Z-scores of male infants without HIV were significantly lower than for female infants without HIV at all follow-up time points. Male infants without HIV had lower length/age and weight/age Z-scores than female infants at the remaining follow-up points, except at 1 month of age. Of a total of 61 infants with HIV, subtype and drug-resistance data were obtained from 37 (60.66%) samples. Infants with HIV were dominated by the CRF01_AE genotype and showed a diversity of mutation sites dominated by non-nucleoside reverse transcriptase inhibitor resistance. CONCLUSION: Our study demonstrates the growth of infants exposed to HIV in southwest China and provides detailed information on subtype distribution and drug resistance of those with HIV. Nutritional support and drug-resistance surveillance for infants exposed to HIV need to be strengthened.

INTRODUCTION: During postherpetic neuralgia (PHN), the cerebral spinal fluid (CSF) possesses the capability to trigger glial activation and inflammation, yet the specific changes in its composition remain unclear. Recent findings from our research indicate elevations of central bone morphogenetic protein 4 (BMP4) during neuropathic pain (NP), serving as an independent modulator of glial cells. Herein, the aim of the present study is to test the CSF-BMP4 expressions and its role in the glial modulation in the process of PHN. METHODS: CSF samples were collected from both PHN patients and non-painful individuals (Control) to assess BMP4 and its antagonist Noggin levels. Besides, intrathecal administration of both CSF types was conducted in normal rats to evaluate the impact on pain behavior, glial activity, and inflammation.; Additionally, both Noggin and STAT3 antagonist-Stattic were employed to treat the PHN-CSF or exogenous BMP4 challenged cultured astrocytes to explore downstream signals. Finally, microglial depletion was performed prior to the PHN-CSF intervention so as to elucidate the microglia-astrocyte crosstalk. RESULTS: BMP4 levels were significantly higher in PHN-CSF compared to Control-CSF (P < 0.001), with a positive correlation with pain duration (P < 0.05, r = 0.502). Comparing with the Control-CSF producing moderate paw withdrawal threshold (PWT) decline and microglial activation, PHN-CSF further exacerbated allodynia and triggered both microglial and astrocytic activation (P < 0.05). Moreover, PHN-CSF rather than Control-CSF evoked microglial proliferation and pro-inflammatory transformation, reinforced iron storage, and activated astrocytes possibly through both SMAD159 and STAT3 signaling, which were all mitigated by the Noggin application (P < 0.05). Next, both Noggin and Stattic effectively attenuated BMP4-induced GFAP and IL-6 upregulation, as well as SMAD159 and STAT3 phosphorylation in the cultured astrocytes (P < 0.05). Finally, microglial depletion diminished PHN-CSF induced astrogliosis, inflammation and endogenous BMP4 expression (P < 0.05). CONCLUSION: Our study highlights the role of CSF-BMP4 elevation in glial activation and allodynia during PHN, suggesting a potential therapeutic avenue for future exploration.

BACKGROUND: There are giant steps taken in the introduction of the novel malaria vaccine poised towards reducing mortality and morbidity associated with malaria. OBJECTIVES: This study aimed to determine the knowledge of malaria vaccine and factors militating against willingness to accept the vaccine among mothers presenting in nine hospitals in Enugu metropolis. METHODS: This was a cross-sectional study carried out among 491 mothers who presented with their children in nine hospitals in Enugu metropolis, South-East Nigeria. A pre-tested and interviewer-administered questionnaire was used in this study. RESULTS: A majority of the respondents, 72.1% were aware of malaria vaccine. A majority of the respondents, 83.1% were willing to receive malaria vaccine. Similarly, a majority of the mothers, 92.9%, were willing to vaccinate baby with the malaria vaccine, while 81.1% were willing to vaccinate self and baby with the malaria vaccine. The subjects who belong to the low socio-economic class were five times less likely to vaccinate self and baby with malaria vaccine when compared with those who were in the high socio-economic class (AOR = 0.2, 95% CI 0.1-0.5). Mothers who had good knowledge of malaria vaccination were 3.3 times more likely to vaccinate self and baby with malaria vaccine when compared with those who had poor knowledge of malaria vaccination (AOR = 3.3, 95% CI 1-6-6.8). CONCLUSION: Although the study documented a high vaccine acceptance among the mothers, there exists a poor knowledge of the malaria vaccine among them.

BACKGROUND: The shared provider responsibility between married couples does not translate to equally shared division of childcare (CC) and household labor. While some marriages contain highly positive aspects, marriages may also simultaneously contain both positive and negative aspects. The negativity in these relationships can negate the positivity and could potentially lead to the detriment of mothers' health. PURPOSE: We examined mothers' ambulatory blood pressure (ABP) associated with their marital relationship quality and perceived equity with her spouse on CC and household tasks. METHODS: We investigate these associations using a mixed multilevel model analysis on a sample of 224 mothers in heterosexual marriages, all of whom had children under the age of 18 years currently living in the home. RESULTS: Mothers' perception of equity in the division of CC responsibilities contributed to lower ABP. Additionally, mothers in supportive marital relationships (low negativity and high positivity) had lower ABP than those in ambivalent relationships (both high negativity and positivity). There was a crossover interaction such that the effect of relationship quality on ABP was moderated by the perception of equity in the division of CC. For mothers who report doing all the CC, they had lower ABP if they had a supportive marital relationship compared with mothers in ambivalent relationships. Whereas mothers who report more equity in CC and have a supportive relationship have higher ABP compared with mothers in ambivalent relationships. CONCLUSIONS: This study has implications related to dynamics within marital relationships. These results demonstrate important relational influences on mothers' ABP.
Married mothers disproportionately shoulder the responsibilities of childcare (CC) and household labor. This inequity of the division of family responsibilities can negatively affect the relationship between husbands and wives with marital satisfaction being higher when the load is more equally shared between partners. Additionally, marital satisfaction is associated with numerous health benefits including lower blood pressure. We examined mothers' ambulatory blood pressure (ABP) associated with their marital relationship quality and perceived equity with her spouse on CC and household tasks on a sample of 224 mothers in heterosexual marriages. Mothers' perception of equity in the division of CC responsibilities contributed to lower ABP. Additionally, mothers in supportive marital relationships had lower ABP than those reporting less supportive relationships. There was an interaction between the perception of equity in the division of CC and the effect that relationship quality had on mothers' ABP. Mothers who reported doing all the CC had lower ABP if they had a supportive marital relationship compared with mothers in less supportive relationships. Whereas mothers who reported more equity in CC and had a supportive relationship had higher ABP compared with mothers in less supportive relationships.

BACKGROUND: Altered intracellular Ca2+ homeostasis in neonatal platelets has been previously reported. This study aims to examine the changes in the Ca2+ entry through the store-operated calcium entry (SOCE) mechanism in neonatal platelets. METHODS: Human platelets from either control women, mothers, and neonates were isolated and, following, were fixed after being treated as required. Platelet samples were analyzed by Western blotting, qRT-PCR, and MALDITOF/TOF. Ca2+ homeostasis was also determined. Culture cells were used as surrogated of platelets to overexpress the proteins of interest to reproduce the alterations observed in platelets. RESULTS: Altered TG (thapsigargin)-evoked SOCE, alternative molecular weight form of STIM1 (stromal interaction molecule 1; s-STIM1 [short STIM1 isoform (478 aa)], around 60 kDa) and overexpression of SARAF (SOCE-associated regulatory factor) were found in neonatal platelets as compared to maternal and control women platelets. s-STIM1 may result due to CAPN1 (calpain1)-dependent processing, as confirmed in platelets and MEG01 cells by using calpeptin and overexpressing CAPN1, respectively. In HEK293 (STIM1 and STIM2 [stromal interaction molecule 2] double knockout) cells transfected either with c-STIM1 (canonical STIM1 [685 aa]), s-STIM1 (478), STIM1B (540), and CAPN1 overexpression plasmids, we found s-STIM1 and c-STIM1, except in cells overexpressing s-STIM1 (478) that lacked CAPN1 target residues. These results and the in silico analysis, lead us to conclude that STIM1 is cleaved at Q496 by CAPN1. Ca2+ imaging analysis and coimmunoprecipitation assay using MEG01 and HEK293 cells overexpressing SARAF together with s-STIM1 (478) reported a reduced slow Ca2+-dependent inactivation, so reproducing the Ca2+-homeostasis pattern observed in neonatal platelets. CONCLUSIONS: CAPN1 may cleave STIM1 in neonatal platelets, hence, impairing SARAF coupling after SOCE activation. s-STIM1 may avoid slow Ca2+-dependent inactivation and, subsequently, results in an enhanced TG-evoked SOCE as observed in neonatal platelets.

Maternal diet influences breast milk nutritional profile; however, it is unclear which nutrients and contaminants are particularly responsive to short- and long-term changes in maternal intake, and the impact of specific exclusion diets, such as vegan or vegetarian. This study systematically reviewed the literature on the effects of maternal nutrient intake, including exclusion diets, on both the nutrient and contaminant content of breast milk. The electronic databases, PubMed, CENTRAL, Web of Science and CINALH were systematically searched until 4 June 2023, with additionally searches of reference lists (PROSPERO, CRD42020221577). The quality of the studies was examined using Cochrane Risk of Bias tool and Newcastle-Ottawa scale. Eighty-eight studies (n 6577) met the search criteria. Due to high heterogeneity, meta-analysis was not possible. There was strong evidence of response to maternal intakes for DHA and EPA, vitamins A, E and K, iodine and Se in breast milk composition, some evidence of response for α-linolenic acid, B vitamins, vitamin C and D, ovalbumin, tyrosine and contaminants, and insufficient evidence to identify the effects arachidonic acid, Cu, Fe, Zn and choline. The paucity of evidence and high heterogeneity among studies reflects the need for more high-quality trials. However, this review identified the importance of maternal intake in the nutritional content of breast milk for a wide range of nutrients and supports the recommendation for supplementation of DHA and vitamin B12 for those on restrictive diets.

BACKGROUND: Congenital anomalies are common, but the possibility that maternal cancer increases the chance of having a child with a birth defect is not fully understood. OBJECTIVES: To examine the association between maternal cancer before or during pregnancy and the risk of birth defects in offspring. METHODS: We conducted a retrospective cohort study of live births in Quebec, Canada, between 1989 and 2022 using hospital data. The main exposure measure was maternal cancer before or during pregnancy. The outcome included birth defects detected in offspring during gestation or at birth. We estimated risk ratios (RR) and 95% confidence intervals (CI) for the association of maternal cancer with birth defects using log-binomial regression models adjusted for potential confounders. RESULTS: In this study of 2,568,120 newborns, birth defects were present in 6.0% and 6.7% of infants whose mothers had cancer before or during pregnancy, respectively, compared with 5.7% of infants whose mothers never had cancer. Cancer during pregnancy was associated with heart (RR 1.58, 95% CI 1.03, 2.44), nervous system (RR 4.05, 95% CI 2.20, 7.46) and urinary defects (RR 1.72, 95% CI 1.01, 2.95). Among specific types of malignancies during pregnancy, breast cancer was the most prominent risk factor for birth defects (RR 1.55, 95% CI 1.02, 2.37). Cancer before pregnancy was not associated with any type of birth defect or with defects overall (RR 1.01, 95% CI 0.92, 1.11). Moreover, no specific type of cancer before pregnancy was associated with an increased risk of birth defects. CONCLUSIONS: Maternal cancer during pregnancy is associated with the risk of congenital anomalies in offspring, however, cancer before pregnancy is not associated with this outcome.

Understanding factors associated with internalized HIV-related stigma among mothers living with HIV may improve health outcomes. We examined factors (age, race/ethnicity, education, income, employment, marital status, health limitations, and years since HIV diagnosis) associated with internalized HIV-related stigma among biological mothers of children enrolled in the Surveillance Monitoring for ART Toxicities study of the US-based Pediatric HIV/AIDS Cohort Study. Stigma was measured with the Internalized HIV Stigma Scale (IHSS), completed biennially at their child's 11-17-year visits. Linear regression models were fit with generalized estimating equations to evaluate the association between the factors of interest and internalized HIV-related stigma using all completed IHSS surveys. Among 438 eligible mothers, the mean IHSS score was 43.7 (SD = 19.5). Higher IHSS scores were observed for widowed women compared to married women, with an estimated mean difference of 8.91 (95% CI: 2.25, 15.57) after adjusting for age, education, income, and health limitations. Years since HIV diagnosis was associated with internalized HIV-related stigma. For every year of increase since HIV diagnosis, IHSS scores decreased by 0.54 per year, after adjusting for age (95% CI: -0.92, -0.17). Interventions to reduce internalized HIV-related stigma should target mothers who are widowed and those with a more recent HIV diagnosis.

PURPOSE: To examine the association of prepregnancy dietary patterns with postpartum weight retention at 6 months (PPWR6) among Lebanese and Qatari women. METHODS: Data for this study were derived from the Mother and Infant Nutrition Assessment (MINA) prospective cohort study conducted in Lebanon and Qatar. Pregnant women were recruited during their first trimester and were followed up for three years. For the purpose of this study, data belonging to sociodemographic characteristics of participants, prepregnancy dietary intake, prepregnancy BMI as well as weight retention at 6 months were used. Dietary intake was examined using a 98-item food frequency questionnaire. Principal component analysis was used for the derivation of dietary patterns. The associations of dietary patterns with PPWR6 were examined using simple and multiple linear regressions. RESULTS: Data was available for 177 participants (Lebanon: 93; Qatar: 84). Mean PPWR6 was 4.05 ± 5.29 kg. Significantly higher PPWR6 was observed among participants with pre-pregnancy overweight/obesity and among those with excessive gestational weight gain. Two dietary patterns were identified: the "Western" and the "Varied" patterns. After adjustment for confounders, a positive association was observed between the 'Western' pattern scores and PPWR6 (ß = 1.27; 95% CI 0.68-1.86; p value: < 0.0001). CONCLUSION: Higher adherence to the Western pattern was associated with higher PPWR6 amongst women, hence underscoring the importance of public health interventions aimed at fostering healthier dietary habits during this crucial stage of the lifecycle.

INTRODUCTION: Respiratory distress (RD) is the most common cause of admission to the Neonatal Intensive Care Unit (NICU). The role of Vitamin D in the development and fortification of fetal pulmonary architecture and the synthesis of surfactants is well-documented. While different serum levels of 25-hydroxyvitamin D (Vit. D) have been studied for their diagnostic significance in RD, there is limited research on how it specifically affects the development of respiratory problems in infants and their mothers. The purpose of the present study is a systematic review and meta-analysis to evaluate the correlation between serum levels of Vit. D in mothers and newborns with RD, and to determine the impact of treating either population on the clinical outcomes of afflicted infants. METHODS: A comprehensive literature search was conducted across various databases, including PubMed, ScienceDirect, Cochrane Library, ISI, and Google Scholar, using a combination of keywords such as RD, diagnosis, vitamin D, mothers, infants, vitamin D supplementation, Respiratory distress syndrome(RDS), and Transient Tachypnea of Newborn (TTN). The search was carried out until March 2024.The level of vitamin D in both mothers and their infants was systematically extracted and analyzed to determine the diagnostic efficacy of Vit. D levels. The mean difference (MD) was calculated along with a 95% confidence interval to determine the association between the Vit. D levels in newborns and their mothers and the likelihood of RD, RDS and TTN in infants. To assess potential publication bias, a funnel plot was generated and Egger's regression test was applied, utilizing a random-effects model. RESULTS: Initially a total of 298 relevant articles was retrieved. Among them, 17 articles with a total of 1,582 infants (745 cases and 837 healthy controls) met the criteria as eligible studies. Of these six were prospective cohort studies, four retrospective case-control studies, four randomized controlled trials (RCTs), and three descriptive-analytical studies. The meta-results revealed a significant association between Vit. D levels and risk of RD in infants (MD = 6.240, 95 %CI: 4.840-7.840, P < 0.001) and mothers (MD = 8.053, 95 %CI: 4.920-11.186, P < 0.001). Furthermore, a strong association was found for risk of RDS (MD = 5.493, 95 %CI: 3.356-7.631, P < 0.001) in infants and TTN (MD = 6.672, 95 %CI: 4.072-9.272, P < 0.001), (MD = 8.595, 95%CI: 4.604-12.586, P < 0.001) both in infants and mothers. Administering 50,000 units of vitamin D to mothers (MD = 8.595, 95 %CI: 4.604-12.586, P < 0.001) prior to childbirth was observed to reduce the likelihood of RD in newborns by 64 % (RR = 0.36, 95 %CI: 0.23-0.57, P < 0.001). Supplemental vitamin D provided to infants was associated with several clinical benefits. CONCLUSION: Our meta-results indicated a significant correlation between serum levels of Vit. D and the risk of RD, RDS and TTN in infants. Prophylactic maternal administration of vitamin D plays a protective role against neonatal RD. Additionally, providing vitamin D to premature infants has shown a significant impact in reducing the incidence of respiratory complications.
RESUMEN
BACKGROUND: Experiencing childbirth as traumatic is common and can have long-lasting negative consequences for women's mental health. However, fostering a sense of social identity has been shown to protect psychological wellbeing and mental health during life transitions, such as entering parenthood. This study therefore investigated the relationship between traumatic childbirth and first-time mothers' social identity and their psychological wellbeing, and more specifically whether strength of identity as a first-time mother protected psychological wellbeing following traumatic childbirth. METHOD: Women over the age of 18 who were living in the UK and had given birth to their first child in the past nine months were recruited to the study from clinical and community settings. They completed digital self-report questionnaires about their birth experience, social identity, mental health, and psychological wellbeing. Women who perceived themselves to have had a traumatic birth (the trauma group; N = 84) were compared to women who did not perceive themselves to have had a traumatic birth (the control group, N = 39). T-tests and chi square tests assessed preliminary group differences before multivariate analyses of covariance controlled for covariates. Post-hoc tests identified the direction of differences. Multiple regression and moderation analyses analysed interaction effects. RESULTS: The trauma group had significantly lower psychological wellbeing (mean = 41.5, 95% CI [39.4-43.7], p = .008, partial η2 = 0.059), compared to the control group (mean = 48.4, 95% CI [45.3-51.5]), but the two groups did not differ in the strength of their first-time mother identity, which was high across both groups. Strength of identity did not moderate the relationship between traumatic childbirth and psychological wellbeing. Giving birth by caesarean section independently reduced the strength of the first-time mother identity (p = .017, partial η2 = 0.049). All analyses controlled for emotional and practical support, perceptions of healthcare staff, and mode of birth. CONCLUSIONS: Having a traumatic birth was associated with lower psychological wellbeing, and the strength of first-time mother identity does not appear to moderate this relationship. Factors such as mode of birth may be more important. Further research, including longitudinal designs, is needed to understand the relationship between these constructs and identify more effective ways of protecting first-time mothers' mental health.

BACKGROUND: The hospitalization of a preterm infant in the NICU can lead to mental health difficulties in parents, but not much is known how paternal anxiety might affect the mother-infant relationship. METHODS: This prospective cohort study is a secondary analysis investigating how paternal anxiety levels might affect maternal bonding in the NICU using the dataset of the multinational pragmatic randomized controlled trial LongSTEP. A linear mixed-effects model was used for correlations of paternal anxiety (GAD-7) and maternal bonding (PBQ) at NICU discharge, and at 6 and 12 months infant corrected age. Secondary analyses examined effects on paternal anxiety related to: site (Argentina, Colombia, Israel, Norway, and Poland), maternal depression (EPDS), infant gestational age at birth, paternal age, and type of pregnancy. RESULTS: Paternal anxiety did not predict maternal bonding at NICU discharge (p = 0.096), at 6 months (p = 0.316), or at 12 months infant corrected age (p = 0.473). Secondary outcomes showed a statistically significant site effect, with higher paternal anxiety levels at the two Colombian sites at baseline (p = 0.014 and p = 0.020) and for one site at discharge (p = 0.012), but not for paternal age (p = 0.925 and p = 0.793), infant gestational age at birth (p = 0.974 and p = 0.686 and p = 0.340), or type of pregnancy (p = 0.381). Maternal depression predicted paternal anxiety at baseline (p < 0.001) and at discharge (p = 0.003). CONCLUSIONS: In this study, paternal anxiety did not predict maternal bonding. Paternal anxiety varied by site, indicating a need for research on potential cultural differences in manifestation of paternal anxiety. Maternal depression predicted paternal anxiety, confirming a previously reported correlation. Further research on variations in paternal mental health in the neonatal period is warranted, as well as exploration of the social contagion of mental health in preterm parents. TRIAL REGISTRATION: ClinicalTrials.gov NCT03564184.

BACKGROUND: In Switzerland, foreigners account for 25.3% of the permanent resident population, and the fertility rate of migrant women is higher than that of Swiss women. However, migrant women from non-European countries are more likely to report having negative childbirth experiences than Swiss women. For example, during pregnancy, Chinese migrant mothers often felt dissatisfied with the follow-up pregnancy complications and lacked information on medical procedures and prenatal courses. In this paper, we explored their childbirth experiences in Swiss hospitals and how Swiss healthcare providers supported them. METHOD: A qualitative study employing in-depth, semi-structured interviews was conducted with 14 Chinese mothers and 13 family members. All interviews were audio-recorded, transcribed, and translated into English for data analysis. Thematic analysis was employed to generate a detailed description. RESULTS: Three main themes were extracted from the transcripts: (1) Sense of security, (2) Intrapartum care, and (3) Postpartum needs. CONCLUSIONS: Our study shows Chinese migrant mothers prioritized giving birth in a physically and psychologically safe environment, with pain control and practical and emotional support from their intimate partners. They desired a physiological labor and birth with minimal obstetric interventions. Our research also reveals their postpartum needs, emphasizing the importance of postpartum support and obtaining culturally sensitive care during their postpartum hospital stay. The study adds new knowledge of specific migrant studies in Switzerland, as called for by the Swiss Federal Office of Public Health. The results call for the transcultural care skills training of Swiss healthcare providers to enable migrant women to have a more positive childbirth experience.

BACKGROUND: Establishing successful lactation in mothers of very low birth weight (VLBW, <1500g) infants requires structured lactation support. Little is known about mothers' perspectives on lactation support in German neonatal intensive care units (NICUs). METHODS: This paper features a convergent mixed-method approach that includes a retrospective, cross-sectional questionnaire and interview data to showcase mothers' perceptions of lactation support in NICUs. Content analysis of the interviews (n = 12) and a descriptive analysis of quantitative data (n = 533) were performed to illustrate the current status and need for lactation support in German NICUs. RESULTS: The results show that lactation support in German NICUs is often inadequate and does not comply with recommendations based on the existing literature to encourage pumping and breastfeeding in mothers. The data imply that even if lactation is successfully initiated in most cases, it is often not maintained over time, which may be due to a lack of personal support and consistent information. CONCLUSION: The overall structures and institutional guidelines for lactation support should be encouraged to promote nutrition with mother´s own milk in German NICUs.

BACKGROUND: Maternal satisfaction during delivery services is considered an important indicator of the quality of healthcare in a hospital setting and determines the uptake of services during subsequent pregnancies. However, there is limited information on the magnitude of women's satisfaction during delivery services in the study area. Thus, this study aimed to assess factors associated with maternal satisfaction with delivery services among women who gave birth at public hospitals in Guji Zone, Southern Ethiopia. METHOD: A facility-based cross-sectional study was conducted at public hospitals in Guji Zone from December 1, 2020, to January 30, 2021. Two hundred forty-nine women who gave birth at public hospitals were recruited by a systematic random sampling technique. The collected data were entered into the Epi Info 7 software and then exported to SPSS Version 26 for analysis. A logistic regression model was employed to identify the association between independent variables and maternal satisfaction during delivery services. A P-value less than 0.05 and an Adjusted Odds Ratio with 95% CI was computed to determine the strength of the association between these variables. RESULT: In this study, 138(55.4%), 95% CI (49.1-61.7) women were satisfied with delivery. Mothers who delivered through cesarean section (AOR = 2.92, 95% CI: 1.34-6.33), privacy assured (AOR = 3.14, 95% CI: 1.76-5.59), shorter duration of labor (AOR = 2.82, 95% CI: 1.64-4.62), waiting time ≤ 30 min (AOR = 5.15,95% CI:1.99-13.32) and normal fetal outcome (AOR = 2.63, 95% CI:1.42-4.85) were associated with mothers satisfaction with delivery care services. CONCLUSION: The overall magnitude of women's satisfaction with delivery services is low, which is below the national client satisfaction target of ≥ 85%. Factors such as mode of delivery, assured privacy, short duration of labor, waiting time ≤ 30 min, and good fetal outcome were significantly associated with women's satisfaction with delivery services. Therefore, healthcare providers should provide better management during intrapartum childbirth or emergency obstetric care to improve fetal outcomes during delivery services. In addition, health facility managers should avail infrastructure that helps to maintain the privacy of women who give birth in the facility.

BACKGROUND: In the postpartum period, there are numerous changes in the physical and psychological dimensions of women, which reduce the quality of life of women. The aim of this study was to compare the health-promoting lifestyle of mothers with vaginal delivery and cesarean delivery in the postpartum period. METHODS: This cross-sectional study was conducted on 77 pregnant women who had delivered vaginal or by cesarean section at Shohadaye Behshahr Hospital and were selected based on inclusion criteria. If the women were willing to participate in the study, a demographic questionnaire was completed, and the telephone numbers of the subjects were recorded so that the Porsline health-promoting lifestyle questionnaire could be sent to them. Data were analyzed with SPSS 22 using the T test, chi-square test and Repeated Measure ANOVA. RESULTS: There was no difference in the average score of health-promoting lifestyle and its dimensions between the two groups of vaginal delivery and cesarean section at two and six weeks after delivery. However, in both groups, the total score of health-promoting lifestyle decreased significantly over time (P < 0.001). CONCLUSIONS: There was no difference in health-promoting lifestyle between mothers with vaginal and mothers with cesarean delivery at two weeks and six weeks after delivery. This requires more attention from policy makers to make vaginal childbirth more convenient, and by reducing complications after vaginal childbirth, they can improve women's healthy lifestyles and, in turn, families. Also, it seems that the other variables apart from the method of delivery should be considered, and it is necessary to distinguish these variables such as routine episiotomy in order to prevent the decrease in the level of health-promoting behaviors among women during puerperium period.
