RESUMO

BACKGROUND: Practitioners in the field of assisted reproductive technology (ART) continually seek alternative or adjunct treatments to improve ART outcomes. This Cochrane review investigates the adjunct use of synthetic versions of two naturally produced hormones, dehydroepiandrosterone (DHEA) and testosterone (T), in assisted reproduction. Steroid hormones are proposed to increase conception rates by positively affecting follicular response to gonadotrophin stimulation. This may lead to a greater oocyte yield and, subsequently, an increased chance of pregnancy. OBJECTIVES: To assess the effectiveness and safety of DHEA and T as pre- or co-treatments in infertile women undergoing assisted reproduction. SEARCH METHODS: We searched the following electronic databases up to 8 January 2024: the Gynaecology and Fertility Group (CGF) Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO, and trial registries for ongoing trials. We also searched citation indexes, Web of Science, PubMed, and OpenGrey. We searched the reference lists of relevant studies and contacted experts in the field for any additional trials. There were no language restrictions. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing DHEA or T as an adjunct treatment to any other active intervention, placebo, or no treatment in women undergoing assisted reproduction. DATA COLLECTION AND ANALYSIS: Two review authors independently selected studies, extracted relevant data, and assessed risk of bias. We pooled data from studies using fixed-effect models. We calculated odds ratios (ORs) for each dichotomous outcome. Analyses were stratified by type of treatment. We assessed the certainty of evidence for the main findings using GRADE methods. MAIN RESULTS: We included 29 RCTs. There were 1599 women in the intervention group and 1469 in the control group. Apart from three trials, the trial participants were women identified as 'poor responders' to standard in vitro fertilisation (IVF) protocols. The included trials compared either T or DHEA treatment with placebo or no treatment. Pre-treatment with DHEA versus placebo/no treatment: DHEA likely results in little to no difference in live birth/ongoing pregnancy rates (OR 1.30, 95% confidence interval (CI) 0.95 to 1.76; I² = 16%, 9 RCTs, N = 1433, moderate certainty evidence). This suggests that in women with a 12% chance of live birth/ongoing pregnancy with placebo or no treatment, the live birth/ongoing pregnancy rate in women using DHEA will be between 12% and 20%. DHEA likely does not decrease miscarriage rates (OR 0.85, 95% CI 0.53 to 1.37; I² = 0%, 10 RCTs, N =1601, moderate certainty evidence). DHEA likely results in little to no difference in clinical pregnancy rates (OR 1.18, 95% CI 0.93 to 1.49; I² = 0%, 13 RCTs, N = 1886, moderate certainty evidence). This suggests that in women with a 17% chance of clinical pregnancy with placebo or no treatment, the clinical pregnancy rate in women using DHEA will be between 16% and 24%. We are very uncertain about the effect of DHEA on multiple pregnancy (OR 3.05, 95% CI 0.47 to 19.66; 7 RCTs, N = 463, very low certainty evidence). Pre-treatment with T versus placebo/no treatment: T likely improves live birth rates (OR 2.53, 95% CI 1.61 to 3.99; I² = 0%, 8 RCTs, N = 716, moderate certainty evidence). This suggests that in women with a 10% chance of live birth with placebo or no treatment, the live birth rate in women using T will be between 15% and 30%. T likely does not decrease miscarriage rates (OR 1.63, 95% CI 0.76 to 3.51; I² = 0%, 9 RCTs, N = 755, moderate certainty evidence). T likely increases clinical pregnancy rates (OR 2.17, 95% CI 1.54 to 3.06; I² = 0%, 13 RCTs, N = 1152, moderate certainty evidence). This suggests that in women with a 12% chance of clinical pregnancy with placebo or no treatment, the clinical pregnancy rate in women using T will be between 17% and 29%. We are very uncertain about the effect of T on multiple pregnancy (OR 2.56, 95% CI 0.59 to 11.20; 5 RCTs, N = 449, very low certainty evidence). We are uncertain about the effect of T versus oestradiol or T versus oestradiol + oral contraceptive pills. The certainty of the evidence was moderate to very low, the main limitations being lack of blinding in the included trials, inadequate reporting of study methods, and low event and sample sizes in the trials. Data on adverse events were sparse; any reported events were minor. AUTHORS' CONCLUSIONS: Pre-treatment with T likely improves, and pre-treatment with DHEA likely results in little to no difference, in live birth and clinical pregnancy rates in women undergoing IVF who have been identified as poor responders. DHEA and T probably do not decrease miscarriage rates in women under IVF treatment. The effects of DHEA and T on multiple pregnancy are uncertain. Data regarding adverse events were very limited; any reported events were minor. Research is needed to identify the optimal duration of treatment with T. Future studies should include data collection on adverse events and multiple pregnancy.

RESUMO

BACKGROUND: Experiencing a miscarriage can have profound psychological implications, and the added strain of the COVID-19 pandemic may have compounded these effects. This study aimed to explore the psychological experiences, assess the levels of psychological distress (depression, anxiety, and post-traumatic stress disorder), and examine the relationships of personal significance of miscarriage and perceived stress with psychological distress of women in North Carolina who suffered a miscarriage of a desired pregnancy between March 30, 2020, and February 24, 2021, of the COVID-19 pandemic, at 14 to 31 months after the loss. METHODS: We conducted a cross-sectional mixed-methods study using a convergent parallel design. A total of 71 participants from North Carolina completed the online survey and 18 completed in-depth interviews. The survey assessed demographics, mental health and reproductive history, personal significance of miscarriage, perceived stress, anxiety, depression, and PTSD. Interview questions asked about the psychological experience of the miscarriage and how the COVID-19 pandemic affected them and their experience. RESULTS: Findings indicated moderate to severe levels of depression, anxiety, and PTSD, which persisted 14 to 31 months post-miscarriage. After conducting hierarchical binary logistic regressions, we found that perceived stress and prior trauma increased the odds of depression, perceived stress increased the odds of anxiety, and personal significance and prior trauma increased the odds of PTSD symptoms 14-31 months post-miscarriage. Notably, a subsequent successful childbirth emerged as a protective factor against depression, anxiety, and PTSD. Qualitative findings depicted emotions such as profound isolation, guilt, and grief. Women noted that additional pandemic-specific stressors exacerbated their distress. The categories identified via conventional content analysis fell under five broader thematic groups: mental health disorders, negative emotions/feelings, positive emotions/feelings, thoughts, and other experiences. CONCLUSIONS: Miscarriage during the COVID-19 pandemic intensified and added complexity to the psychological distress experienced by affected women. The study underscores the need for comprehensive mental health screenings, specialized support for vulnerable groups, and the necessity of trauma-informed care. Providers are strongly encouraged to adopt a multifaceted, individualized approach to patient care that is cognizant of the unique stressors introduced by the pandemic.

RESUMO

We report an epidemic of parvovirus B19 infections in Denmark during the first quarter of 2024, with a peak incidence 3.5 times higher than during the most recent epidemic in 2017. In total, 20.1% (130/648) of laboratory-confirmed cases were pregnant. Severe adverse outcomes were observed among 12.3% (16/130) of pregnant people and included foetal anaemia, foetal hydrops and miscarriage. Parvovirus B19 infection is not systematically monitored, but a national laboratory-based surveillance system is currently being established in Denmark.

RESUMO

Importance: Many studies have reported that the interpregnancy interval (IPI) is a potential modifiable risk factor for adverse perinatal outcomes. However, the association between IPI after live birth and subsequent spontaneous abortion (SA) is unclear. Objective: To investigate the association of IPI after a healthy live birth and subsequent SA. Design, Setting, and Participants: This prospective cohort study used data from 180 921 women aged 20 to 49 years who had a single healthy live birth and planned for another pregnancy and who participated in the Chinese National Free Prepregnancy Checkups Project from January 1, 2010, to December 31, 2020. Statistical analysis was conducted from June 20 to October 5, 2023. Exposure: Interpregnancy interval, defined as the interval between the delivery date and conception of the subsequent pregnancy, was categorized as follows: less than 18 months, 18 to 23 months, 24 to 35 months, 36 to 59 months, and 60 months or longer. Main Outcomes and Measures: The main outcome was SA. Multivariable-adjusted odds ratios (ORs) were calculated by logistic regression models to examine the association between IPI and the risk of SA. Dose-response associations were evaluated by restricted cubic splines. Results: The analyses included 180 921 multiparous women (mean [SD] age at current pregnancy, 26.3 [2.8] years); 4380 SA events (2.4% of all participants) were recorded. A J-shaped association between IPI levels and SA was identified. In the fully adjusted model, compared with IPIs of 18 to 23 months, both short (<18 months) and long (≥36 months) IPIs showed an increased risk of SA (IPIs of <18 months: OR, 1.15 [95% CI, 1.04-1.27]; IPIs of 36-59 months: OR, 1.28 [95% CI, 1.15-1.43]; IPIs of ≥60 months: OR, 2.13 [95% CI, 1.78-2.56]). Results of the subgroup analysis by mode of previous delivery were consistent with the main analysis. Conclusions and Relevance: This cohort study of multiparous women suggests that an IPI of shorter than 18 months or an IPI of 36 months or longer after a healthy live birth was associated with an increased risk of subsequent SA. The findings are valuable to make a rational prepregnancy plan and may facilitate the prevention of SA and improvement in neonatal outcomes.

RESUMO

Importance: Becoming a first-time parent is a major life-changing event and can be challenging regardless of the pregnancy outcome. However, little is known how different adverse pregnancy outcomes affect the father's risk of psychiatric treatment post partum. Objective: To examine the associations of adverse pregnancy outcomes with first-time psychiatric treatment in first-time fathers. Design, Setting, and Participants: This nationwide cohort study covered January 1, 2008, to December 31, 2017, with a 1-year follow-up completed December 31, 2018. Data were gathered from Danish, nationwide registers. Participants included first-time fathers with no history of psychiatric treatment. Data were analyzed from August 1, 2022, to February 20, 2024. Exposures: Adverse pregnancy outcomes including induced abortion, spontaneous abortion, stillbirth, small for gestational age (SGA) and not preterm, preterm with or without SGA, minor congenital malformation, major congenital malformation, and congenital malformation combined with SGA or preterm compared with a full-term healthy offspring. Main Outcomes and Measures: Prescription of psychotropic drugs, nonpharmacological psychiatric treatment, or having a psychiatric hospital contact up to 1 year after the end of the pregnancy. Results: Of the 192 455 fathers included (median age, 30.0 [IQR, 27.0-34.0] years), 31.1% experienced an adverse pregnancy outcome. Most of the fathers in the study had a vocational educational level (37.1%). Fathers experiencing a stillbirth had a significantly increased risk of initiating nonpharmacological psychiatric treatment (adjusted hazard ratio [AHR], 23.10 [95% CI, 18.30-29.20]) and treatment with hypnotics (AHR, 9.08 [95% CI, 5.52-14.90]). Moreover, fathers experiencing an early induced abortion (≤12 wk) had an increased risk of initiating treatment with hypnotics (AHR, 1.74 [95% CI, 1.33-2.29]) and anxiolytics (AHR, 1.79 [95% CI, 1.18-2.73]). Additionally, late induced abortion (>12 wk) (AHR, 4.46 [95% CI, 3.13-6.38]) and major congenital malformation (AHR, 1.36 [95% CI, 1.05-1.74]) were associated with increased risk of nonpharmacological treatment. In contrast, fathers having an offspring being born preterm, SGA, or with a minor congenital malformation did not have a significantly increased risk of any of the outcomes. Conclusions and Relevance: The findings of this Danish cohort study suggest that first-time fathers who experience stillbirths or induced abortions or having an offspring with major congenital malformation had an increased risk of initiating pharmacological or nonpharmacological psychiatric treatment. These findings further suggest a need for increased awareness around the psychological state of fathers following the experience of adverse pregnancy outcomes.

RESUMO

BACKGROUND: Working alliance is a prominent non-specific factor for treatment outcomes in face-to-face and internet-based interventions. The association between working alliance and therapy outcome appears to be time- and disorder-specific, but less is known about the change of working alliance during the intervention and the impact of working alliance in grief-specific interventions. The present study examines the association between the change of working alliance and treatment outcomes in an internet-based intervention for parents who experienced pregnancy loss. METHODS: 228 participants received a grief intervention based on cognitive behavioral therapy with asynchronous text-based therapist feedback. Prolonged grief and related symptoms of traumatic stress, depression, anxiety, and general psychopathology were assessed with validated instruments before and after the intervention. The change of working alliance was assessed using the short version of the Working Alliance Inventory at mid-treatment (session 4) and the end of the treatment (session 10). RESULTS: Data for N = 146 persons was analyzed. Working alliance in total and all subscales increased significantly from sessions 4 to 10. This change in working alliance correlated significantly with a reduction in prolonged grief. Changes in subscales of working alliance also correlated with symptoms of depression and general psychopathology. Regression analysis showed that a change in working alliance predicted a reduction in prolonged grief but did not predict improvements in other grief-related symptoms. CONCLUSION: The results examine the change of working alliance during an internet-based intervention and the association with treatment outcome. A small impact of change in working alliance on treatment outcome of prolonged grief was confirmed, but not on related symptoms. Further research is needed to assess moderators of the alliance-outcome association to improve internet-based interventions. TRIAL REGISTRATION: Not applicable.

RESUMO

In contemporary times, the employment of vitrification freezing technology has led to the widespread adoption of frozen-thawed embryo transfer (FET) worldwide. Meanwhile, hormone replacement therapy (HRT) is a crucial protocol for priming the endometrium during FET cycles. Estrogen is required in HRT cycles for the induction of progesterone receptors and to promote endometrial thickness. However, there is no universal consensus on the treatment duration, dosage regimen, administration route, and target serum estrogen levels. Therefore, this study aimed to offer a comprehensive review of these topics. A shorter duration of estrogen exposure may elevate the risk of early miscarriage, while prolonged exposure to estrogen does not seem to confer advantages to general population and may be attempted in individuals with thin endometrium. Moreover, excessive estrogen levels on the day of progesterone administration may be associated with higher miscarriage rates and lower live birth rates (LBR). To offer more comprehensive guidance for clinical practice, extensive and prospective studies involving a large sample size are warranted to determine the optimal concentration and duration of estrogen exposure.

RESUMO

BACKGROUND: Miscarriage is a frustrating complication of pregnancy that is common among women of reproductive age. Insufficient decidualization which not only impairs embryo implantation but disturbs fetomaternal immune-tolerance, has been widely regarded as a major cause of miscarriage; however, the underlying mechanisms resulting in decidual impairment are largely unknown. METHODS: With informed consent, decidual tissue from patients with spontaneous abortion or normal pregnant women was collected to detect the expression profile of UCHL1. Human endometrial stromal cells (HESCs) were used to explore the roles of UCHL1 in decidualization and dNK modulation, as well as the mechanisms involved. C57/BL6 female mice (7-10 weeks old) were used to construct pregnancy model or artificially induced decidualization model to evaluate the effect of UCHL1 on mice decidualization and pregnancy outcome. RESULTS: The Ubiquitin C-terminal hydrolase L1 (UCHL1), as a deubiquitinating enzyme, was significantly downregulated in decidua from patients with miscarriage, along with impaired decidualization and decreased dNKs. Blockage of UCHL1 led to insufficient decidualization and resultant decreased expression of cytokines CXCL12, IL-15, TGF-ß which were critical for generation of decidual NK cells (dNKs), whereas UCHL1 overexpression enhanced decidualization accompanied by increase in dNKs. Mechanistically, the promotion of UCHL1 on decidualization was dependent on its deubiquitinating activity, and intervention of UCHL1 inhibited the activation of JAK2/STAT3 signaling pathway, resulting in aberrant decidualization and decreased production of cytokines associated with dNKs modulation. Furthermore, we found that inhibition of UCHL1 also disrupted the decidualization in mice and eventually caused adverse pregnancy outcome. CONCLUSIONS: UCHL1 plays significant roles in decidualization and dNKs modulation during pregnancy in both humans and mice. Its deficiency indicates a poor pregnancy outcome due to defective decidualization, making UCHL1 a potential target for the diagnosis and treatment of miscarriage.

RESUMO

BACKGROUND: Chromosomal abnormalities are present in 50 to 60% of miscarriages and in 6 to 19% of stillbirths. Although microarrays are preferred for studying chromosomal abnormalities, many hospitals cannot offer this methodology. OBJECTIVE: To present the results of the cytogenetic analysis of 303 products of conception (POC), which included 184 miscarriages, 49 stillbirths and 17 cases of undefined age. MATERIAL AND METHODS: Karyotyping, fluorescence in situ hybridization, short tandem repeats and microarrays were used, depending on the type of loss and available sample. RESULTS: In 29 POCs we found maternal tissue and were eliminated from the analyses. Informative results were obtained in 250 (91.2 %)/274 cases; the karyotyping success rate was 80.7%; that of single nucleotide polymorphism microarrays, 94.5%; and that of fluorescence in situ hybridization and short tandem repeat, 100%. Cytogenetic abnormalities were observed in 57.6% of miscarriages and in 24.5% of stillbirths; 94% of total anomalies were numerical and 6% were submicroscopic. CONCLUSIONS: Karyotyping with simultaneous short tandem repeat study to rule out contamination of maternal cells is effective for studying miscarriages; in stillbirths, microarrays are recommended.


ANTECEDENTES: Las alteraciones cromosómicas están presentes en 50 a 60 % de los abortos espontáneos y en 6 a 19 % de los mortinatos. Aunque se prefieren los microarreglos para estudiarlos, numerosos hospitales no pueden ofrecerlos. OBJETIVO: Presentar los resultados del estudio citogenético de 303 productos de la concepción (POC), 184 se obtuvieron de abortos espontáneos, 49 fueron mortinatos y en 17 no se identificó la de edad gestacional. MATERIAL Y MÉTODOS: Se empleó cariotipo, hibridación in situ con fluorescencia, secuencias cortas repetidas en tándem y microarreglos, según el tipo de pérdida y la muestra disponible. RESULTADOS: En 29 POC se encontró tejido materno, por lo que fueron eliminados de los análisis. En 250 (91.2 %)/274 casos se obtuvieron resultados informativos; la tasa de éxito del cariotipo fue de 80.7 %; la de los microarreglos de SNP, de 94.5 %; y la de la hibridación fluorescente in situ y la repetición corta en tándem, de 100 %. Se observaron anomalías citogenéticas en 57.6 % de los abortos espontáneos y en 24.5 % de los mortinatos; 94 % de las anomalías fueron numéricas y 6 %, submicroscópicas. CONCLUSIONES: El cariotipo en conjunto con el estudio de secuencias cortas repetidas en tándem para descartar contaminación de células maternas es efectivo para estudiar abortos espontáneos; los microarreglos se recomiendan en los mortinatos.

RESUMO

A significant number of pregnancies are lost in the first trimester and 1-2% are ectopic pregnancies (EPs). Early pregnancy loss in general can cause significant morbidity with bleeding or infection, while EPs are the leading cause of maternal mortality in the first trimester. Symptoms of pregnancy loss and EP are very similar (including pain and bleeding); however, these symptoms are also common in live normally sited pregnancies (LNSP). To date, no biomarkers have been identified to differentiate LNSP from pregnancies that will not progress beyond early gestation (non-viable or EPs), defined together as combined adverse outcomes (CAO). In this study, we present a novel machine learning pipeline to create prediction models that identify a composite biomarker to differentiate LNSP from CAO in symptomatic women. This prospective cohort study included 370 participants. A single blood sample was prospectively collected from participants on first emergency presentation prior to final clinical diagnosis of pregnancy outcome: LNSP, miscarriage, pregnancy of unknown location (PUL) or tubal EP (tEP). Miscarriage, PUL and tEP were grouped together into a CAO group. Human chorionic gonadotrophin ß (ß-hCG) and progesterone concentrations were measured in plasma. Serum samples were subjected to untargeted metabolomic profiling. The cohort was randomly split into train and validation data sets, with the train data set subjected to variable selection. Nine metabolite signals were identified as key discriminators of LNSP versus CAO. Random forest models were constructed using stable metabolite signals alone, or in combination with plasma hormone concentrations and demographic data. When comparing LNSP with CAO, a model with stable metabolite signals only demonstrated a modest predictive accuracy (0.68), which was comparable to a model of ß-hCG and progesterone (0.71). The best model for LNSP prediction comprised stable metabolite signals and hormone concentrations (accuracy = 0.79). In conclusion, serum metabolite levels and biochemical markers from a single blood sample possess modest predictive utility in differentiating LNSP from CAO pregnancies upon first presentation, which is improved by variable selection and combination using machine learning. A diagnostic test to confirm LNSP and thus exclude pregnancies affecting maternal morbidity and potentially life-threatening outcomes would be invaluable in emergency situations.

RESUMO

BACKGROUND: An unintended spontaneous termination of a pregnancy can be a traumatic experience affecting the subsequent life course, but has received little attention in socio-demographic studies on fertility intentions or behavior. The theoretical background of our study draws on considerations from life course research, the Theory of Planned Behavior and the Traits-Desires-Intentions-Behavior framework. OBJECTIVE: This study investigates whether the experience of pregnancy loss changes the fertility desires and intentions of women in their subsequent life course. METHODS: We use 11 waves of the Panel Analysis of Intimate Relationships and Family Dynamics (pairfam) with 5197 women in total, of which 281 women (5.4%) reported a miscarriage. Data have been collected annually in Germany since 2008. We investigate four dependent variables capturing different indicators of the ideational dimension of fertility: Personal ideal number of children, realistic number of (additional) children, intention to have a(nother) child in the next two years and importance of having a(nother) child. We study the intrapersonal changes in these items among women after a pregnancy loss, applying linear fixed effect regression models. Controls include parity, age, partnership status, pregnancy status and the interaction of pregnancy loss with whether the woman already had children before the pregnancy loss. RESULTS: We found that the importance of having a(nother) child and the intention to have a(nother) child in the next two years increase after a pregnancy loss. These patterns can only partially be explained by control variables. By contrast, an effect on the ideal number of children as well as the realistic number of children could not be found. The patterns varied, however, across age and stage in the life course, most importantly between mothers and childless women. CONCLUSIONS: Our results demonstrate that the effect of pregnancy loss on the subsequent life course varies across the indicators used and by duration after the pregnancy loss. Overall, they suggest that specifically the younger women in our sample might perceive pregnancy loss as a temporary crisis in their transition to motherhood, or to having another child, and as an impetus to reinforce their fertility goals, while for older respondents this might mark the end of their fertility career. Against the backdrop of rising ages at childbirth, future research on fertility and reproductive health care should pay more attention to reproductive complications and how affected women can be supported in coping with them.

RESUMO

BACKGROUND: Post-abortion care (PAC) is a crucial component of emergency obstetric care, and many of the primary health care centres (PHC) in the internally displaced person (IDP) camps and host communities in Maiduguri lack it. Improved access to high-quality PACs is essential for meeting the reproductive health needs of the IDPs and reducing the maternal morbidity and mortality that can result from miscarriages. OBJECTIVE: To determine the trend in managing miscarriages in the IDP camps and host communities in Maiduguri and the impact of the volunteer obstetrician scheme (VOS) on PAC. METHODOLOGY: We conducted a longitudinal study in selected PHCs serving IDP camps and host communities in Maiduguri. The study spanned five (5) years, and we compared the management of miscarriages and PAC services one year before the VOS project, two years during the project and two years after the project. During the two-year VOS project, staff manning the PHCs had supportive supervision with hands-on training on PAC. Chi-square for trend and odd ratio with a 95% confidence interval was used as appropriate to compare the trend in PAC services provided during the study period. RESULTS: One thousand eight hundred and eight (1808) women presented with miscarriages, and 1562 (86.4%) required uterine evacuation. Medical evacuation with oral misoprostol was offered to 974 (62.4%), and manual vacuum aspiration (MVA) was used in 422 (27.0%) of the women who needed uterine evacuation. There was a statistically significant rise in the use of medical evacuation throughout the study period (52.2% before VOS, and 71.4% by the second year of VOS) with ꭓ2=41.64 and P<0.001. In comparison, the use of MVA fell from 38.6% in 2015 to 27.7% in 2019 (ꭓ2=34.74 and P<0.001). Similar rising trends were also observed in postabortion family planning acceptance (ꭓ2=22.27, P<0.001). CONCLUSION: The Volunteer Obstetrician Scheme project appears to have improved PAC services, especially medical evacuation and family planning uptake in the PHCs in IDP camps and host communities in Maiduguri, Borno State, Nigeria. We recommend task shifting of PAC services and periodic supportive supervision to ensure the quality of care.


CONTEXTE: Les soins après avortement (PAC) sont une composante cruciale des soins obstétricaux d'urgence, et de nombreux centres de soins de santé primaires (PHC) dans les camps de personnes déplacées internes (PDI) et les communautés d'accueil à Maiduguri en sont dépourvus. Un accès amélioré à des PAC de haute qualité est essentiel pour répondre aux besoins de santé reproductive des PDI et réduire la morbidité et la mortalité maternelles qui peuvent résulter des fausses couches. OBJECTIF: Déterminer la tendance dans la gestion des fausses couches dans les camps de PDI et les communautés d'accueil à Maiduguri et l'impact du Programme de bénévoles obstétriciens (VOS) sur la PAC. MÉTHODOLOGIE: Nous avons mené une étude longitudinale dans des PHC sélectionnés desservant des camps de PDI et des communautés d'accueil à Maiduguri. L'étude a duré cinq (5) ans, et nous avons comparé la gestion des fausses couches et les services de PAC un an avant le projet VOS, deux ans pendant le projet et deux ans après le projet. Pendant les deux ans du projet VOS, le personnel des PHC a bénéficié d'une supervision avec formation pratique sur la PAC. Le chi carré pour la tendance et le rapport de cotes avec un intervalle de confiance de 95% ont été utilisés, le cas échéant, pour comparer la tendance des services de PAC fournis pendant la période de l'étude. RÉSULTATS: Mille huit cent huit (1808) femmes ont présenté des fausses couches, et 1562 (86,4%) ont nécessité une évacuation utérine. Une évacuation médicale avec du misoprostol oral a été proposée à 974 (62,4%), et l'aspiration manuelle sous vide (AMV) a été utilisée chez 422 (27,0%) des femmes ayant besoin d'une évacuation utérine. On a observé une augmentation statistiquement significative de l'utilisation de l'évacuation médicale tout au long de la période de l'étude (52,2% avant le VOS et 71,4% la deuxième année du VOS) avec ꭓ2=41,64 et P<0,001. En revanche, l'utilisation de l'AMV est passée de 38,6% en 2015 à 27,7% en 2019 (ꭓ2=34,74 et P<0,001). Des tendances similaires à la hausse ont également été observées dans l'acceptation de la planification familiale après avortement (ꭓ2=22,27, P<0,001). CONCLUSION: Le projet de Programme de bénévoles obstétriciens semble avoir amélioré les services de PAC, en particulier l'évacuation médicale et l'acceptation de la planification familiale dans les PHC des camps de PDI et des communautés d'accueil à Maiduguri, dans l'État de Borno, au Nigéria. Nous recommandons de déléguer les services de PAC et une supervision de soutien périodique pour garantir la qualité des soins.

RESUMO

OBJECTIVE: The objective of the meta-analysis was to determine the influence of uterine fibroids on adverse outcomes, with specific emphasis on multiple or large (≥ 5 cm in diameter) fibroids. MATERIALS AND METHODS: We searched PubMed, Embase, Web of Science, ClinicalTrials.gov, China National Knowledge Infrastructure (CNKI), and SinoMed databases for eligible studies that investigated the influence of uterine fibroids on adverse outcomes in pregnancy. The pooled risk ratio (RR) of the variables was estimated with fixed effect or random effect models. RESULTS: Twenty-four studies with 237 509 participants were included. The pooled results showed that fibroids elevated the risk of adverse outcomes, including preterm birth, cesarean delivery, placenta previa, miscarriage, preterm premature rupture of membranes (PPROM), placental abruption, postpartum hemorrhage (PPH), fetal distress, malposition, intrauterine fetal death, low birth weight, breech presentation, and preeclampsia. However, after adjusting for the potential factors, negative effects were only seen for preterm birth, cesarean delivery, placenta previa, placental abruption, PPH, intrauterine fetal death, breech presentation, and preeclampsia. Subgroup analysis showed an association between larger fibroids and significantly elevated risks of breech presentation, PPH, and placenta previa in comparison with small fibroids. Multiple fibroids did not increase the risk of breech presentation, placental abruption, cesarean delivery, PPH, placenta previa, PPROM, preterm birth, and intrauterine growth restriction. Meta-regression analyses indicated that maternal age only affected the relationship between uterine fibroids and preterm birth, and BMI influenced the relationship between uterine fibroids and intrauterine fetal death. Other potential confounding factors had no impact on malposition, fetal distress, PPROM, miscarriage, placenta previa, placental abruption, and PPH. CONCLUSION: The presence of uterine fibroids poses increased risks of adverse pregnancy and obstetric outcomes. Fibroid size influenced the risk of breech presentation, PPH, and placenta previa, while fibroid numbers had no impact on the risk of these outcomes.

RESUMO

BACKGROUND:  Spontaneous abortions occur in 12.5% of pregnancies and have a significant impact on the well-being of women. Dissatisfaction with health services is well-documented, but no studies have been conducted in district health services of the Western Cape. The aim was to explore the lived experiences of women presenting with spontaneous abortions to the emergency department at Helderberg Hospital. METHODS:  A descriptive phenomenological qualitative study used criterion-based purposive sampling to identify suitable participants. Data were collected through semi-structured individual interviews. Atlas-ti (version 22) software assisted with data analysis using the framework method. RESULTS:  A total of nine participants were interviewed. There were four main themes: a supportive environment, staff attitudes and behaviour, the impact of time, and sharing of information. The comfort, cleanliness and privacy of the environment were important. COVID-19 had also impacted on this. Showing interest, demonstrating empathy and being nonjudgemental were important, as well as the waiting time for definitive treatment and the time needed to assimilate and accept the diagnosis. In addition, the ability to give relevant information, explain the diagnosis and help patients share in decision-making were key issues. CONCLUSION:  This study highlighted the need for a more person-centred approach and managers should focus on changes to organisational culture through training and clinical governance activities. Attention should be paid to the physical environment, availability of patient information materials and sequential coordination of care with primary care services.Contribution: This study identifies issues that can improve person-centredness and women's satisfaction with care for spontaneous abortion.

RESUMO

OBJECTIVE: to learn the meanings attributed to pregnancy loss by women with Lupus. METHOD: qualitative research, based on Symbolic Interactionism and Grounded Theory. Data collection took place between January and August 2022 through in-depth interviews. Data analysis went through the stages of initial and focused coding. RESULTS: seventeen women participated. The central phenomenon "The climb to motherhood: falls and overcoming" was constructed, consisting of three categories: "Falling to the ground during the climb: the experience of pregnancy loss"; "Getting up and following the path: new attempts to conceive"; and "Remembering the journey: meanings attributed to pregnancy losses". FINAL CONSIDERATIONS: experiencing pregnancy is, analogously, like climbing a mountain, where obstacles need to be overcome to reach the summit. The experience of pregnancy loss is seen as complex, especially when there is fragility in healthcare and a lack of awareness regarding feelings of loss and grief.

RESUMO

BACKGROUND: Plasma microRNAs act as biomarkers for predicting and diagnosing diseases. Reliable non-invasive biomarkers for biochemical pregnancy loss have not been established. We aim to analyze the dynamic microRNA profiles during the peri-implantation period and investigate if plasma microRNAs could be non-invasive biomarkers predicting BPL. METHODS: In this study, we collected plasma samples from patients undergoing embryo transfer (ET) on ET day (ET0), 11 days after ET (ET11), and 14 days after ET (ET14). Patients were divided into the NP (negative pregnancy), BPL (biochemical pregnancy loss), and CP (clinical pregnancy) groups according to serum hCG levels at day11~14 and ultrasound at day28~35 following ET. MicroRNA profiles at different time-points were detected by miRNA-sequencing. We analyzed plasma microRNA signatures for BPL at the peri-implantation stage, we characterized the dynamic microRNA changes during the implantation period, constructed a microRNA co-expression network, and established predictive models for BPL. Finally, the sequencing results were confirmed by Taqman RT-qPCR. RESULTS: BPL patients have distinct plasma microRNA profiles compared to CP patients at multiple time-points during the peri-implantation period. Machine learning models revealed that plasma microRNAs could predict BPL. RT-qPCR confirmed that miR-181a-2-3p, miR-9-5p, miR-150-3p, miR-150-5p, and miR-98-5p, miR-363-3p were significantly differentially expressed between patients with different reproductive outcomes. CONCLUSION: Our study highlights the non-invasive value of plasma microRNAs in predicting BPL.

RESUMO

Background: Human brucellosis is a neglected disease transmitted to humans from animals such as cattle, goats, dogs, and swine. The causative agents are bacteria of the genus Brucella, intracellular pathogens usually confined to the reproductive organs of their animal hosts causing sterility and abortions. The objective of the study was to determine the seroprevalence of brucellosis among women with spontaneous abortions (SAW) and compare this seroprevalence with that of healthy pregnant women (HPW). Methods: The case-control study was designed to determine the seroprevalence and molecular detection of brucellosis in women who suffered from spontaneous abortion and healthy pregnant women of the Haripur District of Pakistan. A total of 770 blood samples (n = 385 for each group) were collected from 9 public and 11 private hospitals in Haripur District from December 2021-March 2023. Data on demographic features, epidemiological variables, and risk factors were collected from each participant by structured questionnaires. Initial screening for brucellosis was performed by Rose Bengal Plate Test followed by qRT-PCR for molecular detection of the genus-specific BCSP-31 gene of Brucella. Results: The study showed that anti-Brucella antibodies were more found in SAW 23.63% (91/385) than in HPW 1.29% (5/385). Brucella specific DNA was amplified in 89.01% (81/91) seropositive samples of SAW. Demographic features and risk factors such as age, urbanicity, socioeconomic status, education, occupation, and animal contact were found significantly associated with brucellosis (p ≤ 0.05). Consumption of unpasteurized raw milk (OR = 18.28, 95%CI: 8.16-40.94) was found highly concomitant with seroprevalence. Conclusion: This study reports the first evidence of involvement of brucellosis in spontaneous abortions in women of Pakistan. The study can be used to develop strategies for risk management during pregnancy, to raise awareness for brucellosis, and develop control programs.

RESUMO

INTRODUCTION: Spontaneous miscarriage is a common complication of early pregnancy. Previous studies have shown that mitochondrial function plays an important role in establishment of a successful pregnancy. Cytochrome c oxidase subunit 4 isoform 1 (COX4I1), a component of electron transport chain complex Ⅳ, is required for coupling the rate of ATP production to energetic requirements. However, there is very limited research on its role in trophoblast biology and how its dysfunction may contribute to spontaneous miscarriage. METHODS: Placental villi (7-10 weeks gestational age) collected from either induced termination of pregnancy or after spontaneous miscarriage were examined for expression of COX4I1. COX4I1 was knocked down by siRNA transfection of primary isolates of EVT cells. Real-time cell analysis (RTCA) and 5-Ethynyl-2'-deoxyuridine (EdU) were used to detect changes in proliferation ability after COX4I1 knockdown of EVT cells. Migration and invasion indices were determined by RTCA. Mitochondrial morphology was observed via MitoTracker staining. Oxidative phosphorylation, ATP production, and glycolysis in COX4I1-deficient cells and controls were assessed by a cellular energy metabolism analyzer (Seahorse). RESULTS: In placental villous tissue, COX4I1 expression was significantly decreased in the spontaneous miscarriage group. Knockdown of COX4I1 inhibited EVT cell proliferation, increased the migration and invasion ability and mitochondrial fusion of EVT cells. Mitochondrial respiration and glycolysis were impaired in COX4I1-deficient EVT cells. Knockdown of MMP1 could rescue the increased migration and invasion induced by COX4I1 silencing. DISCUSSION: Low expression of COX4I1 leads to mitochondrial dysfunction in EVT, resulting in altered trophoblast function, and ultimately to pregnancy loss.
