Objective

To compare DuoStim versus a conventional approach in patients indicated to Preimplantation-Genetic-Testing for both monogenic conditions and aneuploidies (PGT-M + PGT-A).

Study design

Retrospective case-control study. In 5 years, 132 couples indicated to PGT-M + PGT-A who obtained ≤5 blastocysts after a first retrieval were suggested to undergo a second stimulation in the same ovarian cycle. Of them, 55 accepted, while 77 preferred the standard approach. Propensity-Score-Matching method was adopted to produce two matched groups of 41 patients per arm. The primary outcome was the cumulative-live-birth-rate (cLBR) per couple within 1 year from the first oocyte retrieval.

Results

In the DuoStim arm, 100 % of the patients underwent two ovarian stimulations. In the conventional approach group, 85 % discontinued the treatment after a failed first cycle (N = 28/33, 95 %CI:69.1–93.4 %). After DuoStim, 16 couples had ≥ 1 healthy LB (1-year cLBR: 39 %, 95 %CI:25.7–54.3 %), 19 % of them delivered 2 healthy babies after singleton pregnancies (N = 3/16, 95 %CI:6.6–43 %) and 68 % have surplus transferable blastocysts (N = 11/16, 95 %CI:44.4–85.8 %). In the control, 9 couples obtained a healthy LB (1-year cLBR: 22 %, 95 %CI:12.0–36.7 %), and only 1 have surplus transferable blastocysts. Overall, couples opting for DuoStim obtained 3.9 ± 2.5 blastocysts of which 1.2 ± 1.3 transferable, while couples opting for the conventional approach obtained 2.3 ± 2.1 blastocysts of which 0.8 ± 1.0 transferable.

Conclusions

DuoStim may minimize treatment discontinuation and increase the probability to obtain transferable blastocysts in the studied population. Nevertheless, larger prospective studies are required. Also, the suitability of a threshold set at 5 blastocysts should be further validated.
目的比较 DuoStim 与传统方法在单基因和非整倍体植入前遗传检测(PGT-M + PGT-A)患者中的应用。在 5 年中,132 对夫妇接受了 PGT-M + PGT-A,并在第一次取卵后获得了≤5 个囊胚。其中 55 人接受,77 人选择标准方法。采用倾向分数匹配法产生了两个匹配组,每组 41 名患者。主要结果是每对夫妇在第一次取卵后 1 年内的累积活产率(cLBR)。在传统方法组中,85%的患者在第一个周期失败后中止了治疗(N = 28/33,95 %CI:69.1-93.4%)。使用 DuoStim 后,16 对夫妇有≥ 1 个健康的 LB(1 年 cLBR:39%,95%CI:25.7-54.3%),19% 的夫妇在单胎妊娠后分娩了 2 个健康的婴儿(N = 3/16,95%CI:6.6-43%),68% 的夫妇有多余的可转移囊胚(N = 11/16,95%CI:44.4-85.8%)。在对照组中,9 对夫妇获得了健康的 LB(1 年 cLBR:22%,95%CI:12.0-36.7%),只有 1 对夫妇有多余的可移植囊胚。总体而言,选择 DuoStim 的夫妇获得了 3.9 ± 2.5 个囊胚,其中 1.2 ± 1.3 个可移植,而选择传统方法的夫妇获得了 2.3 ± 2.1 个囊胚,其中 0.8 ± 1.0 个可移植。尽管如此,还需要更大规模的前瞻性研究。此外,应进一步验证将阈值设定为 5 个囊胚是否合适。

Introduction

Hypertensive disorders during pregnancy elevate the likelihood of unfavorable outcomes for both mother and fetus. In cases of acute hypertension, several pharmacological interventions are available to lower blood pressure, such as hydralazine, a direct arteriolar vasodilator, and labetalol, a combined alpha and beta-blocker.

Objectives

This systematic review and meta-analysis of randomized controlled trials (RCTs) aims to compare the efficacy and safety of intravenous labetalol and intravenous hydralazine for acute hypertensive disorders during pregnancy.

Methods

We systematically searched PubMed, Embase and Cochrane for studies comparing labetalol versus hydralazine in pregnant patients. The primary outcomes were median arterial blood pressure (MABP), diastolic blood pressure (DBP) and systolic blood pressure (SBP). We performed statistical analyses using R 4.1.1. Heterogeneity was examined with the Cochran Q test and I2 statistics. Risk ratios (RR) and mean differences (MD) with 95% confidence intervals (CI), were computed with a random-effects model.

Results

Nineteen RCTs were included in this meta-analysis, comprising 2,261 patients. Among them, 1,131 (50 %) received treatment with labetalol. There was no statistically significant difference between groups in terms of SBP (MD −1.74; 95 % CI −6.72 to 3.23; p = 0.49; I2 = 93 %), MABP (MD −0.72; 95 % CI −2.34 to 0.90; p = 0.39; I2 = 0 %), DBP (MD 0.25; 95 % CI −4.72 to 5.21; p = 0.92; I2 = 96 %), tachycardia (RR 0.42; 95 % CI 0.15 to 1.18; p = 0.099; I2 = 41 %), and placenta abruption (RR 0.42; 95 % CI 0.15 to 1.16; p = 0.093; I2 = 0 %). However, labetalol significantly reduced maternal hypotension (RR 0.26; 95 % CI 0.21 to 0.33; p < 0.001; I2 = 41 %) compared with hydralazine.

Conclusion

This systematic review and meta-analysis of RCTs found that labetalol and hydralazine were efficient for hypertension disorders in pregnancy. However, labetalol reduced the incidence of maternal hypotension.
引言妊娠期高血压疾病会增加对母亲和胎儿不利的可能性。在急性高血压的情况下,有几种药物可用于降低血压,如肼屈嗪(一种直接扩张动脉血管的药物)和拉贝洛尔(一种α和β联合受体阻滞剂):本研究对随机对照试验(RCTs)进行了系统回顾和荟萃分析,旨在比较静脉注射拉贝洛尔和静脉注射水拉嗪治疗妊娠期急性高血压疾病的有效性和安全性:我们系统地检索了 PubMed、Embase 和 Cochrane 中对妊娠期患者使用拉贝洛尔和肼屈嗪进行比较的研究。主要结果为中位动脉血压(MABP)、舒张压(DBP)和收缩压(SBP)。我们使用 R 4.1.1 进行了统计分析。异质性采用 Cochran Q 检验和 I2 统计量进行检验。采用随机效应模型计算风险比(RR)和平均差(MD)及 95% 置信区间(CI):本次荟萃分析共纳入 19 项研究,包括 2,261 名患者。其中 1,131 人(50%)接受了拉贝洛尔治疗。在 SBP(MD -1.74; 95 % CI -6.72 to 3.23; p = 0.49; I2 = 93 %)、MABP(MD -0.72; 95 % CI -2.34 to 0.90; p = 0.39; I2 = 0 %)、DBP(MD 0.25; 95 % CI -4.72 to 5.21; p = 0.92; I2 = 96 %)、心动过速(RR 0.42; 95 % CI 0.15 to 1.18; p = 0.099; I2 = 41 %)和胎盘早剥(RR 0.42; 95 % CI 0.15 to 1.16; p = 0.093; I2 = 0 %)。然而,与肼屈嗪相比,拉贝洛尔能显著降低产妇低血压(RR 0.26;95 % CI 0.21 至 0.33;p 2 = 41 %):这项系统性回顾和荟萃分析研究发现,拉贝洛尔和氢氯吡嗪对妊娠期高血压疾病有很好的疗效。然而,拉贝洛尔降低了产妇低血压的发生率。

Objective

To assess the variation between countries for routine transvaginal ultrasound assessment of the cervical length and interventions offered to prevent preterm birth (PTB).

Study Design

An anonymous digital questionnaire was sent out between August and October 2023 to delegates of the European Spontaneous Preterm Birth Congress. Outcomes assessed included method, indications (i.e. singleton pregnancy in women with or without a history of PTB, or a multiple pregnancy), timing and frequency of routine cervical length measurement, interventions offered to pregnant women with a short cervix or a history of PTB, and advice on physical- and sexual activity.

Results

In total, 247 visitors of the European Spontaneous Preterm Birth Congress were approached for this study and 103 (42 %) participants completed the questionnaire representing 15 countries. Most participants worked in a Public/University hospital (n = 54, 53 %) and worked as a specialist (registrar or consultant; n = 84, 82 %). In most countries, the cervix was measured via a straight-line method without the cervical isthmus, but variety existed also within countries. Routine cervical length measurement in women with no prior PTB or a multiple pregnancy is rarely performed in the first trimester. For women with a history of PTB, 39 (38 %) respondents from six countries reported to start serial cervical measurement in the first trimester and 99 (96 %) from 14 countries in the second trimester. Follow-up for women at risk for PTB mainly occurs fortnightly (n = 40, 39 %) or monthly (n = 14, 14 %). However, follow-up is often individualized according to patient’s history and/or cervical length. In women with a history of PTB or a short cervix progesterone is administered vaginally (n = 99, 96 %), however dosage vary between 100 mg and 400 mg daily. The timing and gestational age at which a (primary/secondary/tertiary) vaginal cerclage is offered widely differ between countries (e.g. up to 24–28 weeks of gestation for a secondary cerclage). Advice on restrictions regarding sexual activity in pregnancy is frequently prescribed for women with a short cervix (n = 38, 37 %).

Conclusion

Substantial variation exist between and within countries regarding the indications and timing of cervical length measurement and interventions offered. There is a need for a more universal approach to manage patients at risk for PTB based on the existing evidence.
研究设计于 2023 年 8 月至 10 月间向欧洲自发性早产大会的代表们发出了一份匿名数字问卷。评估的结果包括方法、适应症(即有或无早产史的女性单胎妊娠,或多胎妊娠)、常规宫颈长度测量的时间和频率、为宫颈过短或有早产史的孕妇提供的干预措施,以及关于身体活动和性活动的建议。结果本研究共接触了 247 名欧洲自发性早产大会的来访者,有 103 名(42%)代表 15 个国家的参与者填写了问卷。大多数参与者在公立/大学医院工作(54 人,占 53%),并且是专科医生(注册医师或顾问;84 人,占 82%)。大多数国家采用直线法测量宫颈,不测量宫颈峡部,但各国的测量方法也不尽相同。对于未患过宫颈锥切或多胎妊娠的妇女,很少在妊娠头三个月进行常规宫颈长度测量。对于有宫颈锥切病史的妇女,6 个国家的 39 个(38%)受访者表示在妊娠头三个月开始进行连续的宫颈测量,14 个国家的 99 个(96%)受访者表示在妊娠后三个月开始进行连续的宫颈测量。对有 PTB 风险的妇女的随访主要是每两周一次(40 人,占 39%)或每月一次(14 人,占 14%)。不过,随访通常根据患者的病史和/或宫颈长度进行个性化安排。对于有先兆流产史或宫颈过短的妇女,可通过阴道注射黄体酮(人数=99,96%),但剂量在每天 100 毫克至 400 毫克之间。各国提供阴道子宫颈环扎术(一级/二级/三级)的时间和孕周存在很大差异(例如,二级子宫颈环扎术的孕周可达 24-28 周)。结论:在宫颈长度测量的适应症和时间以及干预措施方面,各国之间和各国内部存在巨大差异。有必要在现有证据的基础上,采用更通用的方法来管理宫颈息肉高危患者。

Background

During the last two decades, a few studies have evaluated the common carotid artery (CCA) intima-media thickness (IMT) in women with previous history of pre-eclampsia (pPE) in comparison to women with uncomplicated pregnancies, providing not univocal results. This systematic review and meta-analysis has been designed to summarize the main findings of these studies and to examine the overall influence of pPE on CCA-IMT.

Methods

All studies assessing CCA-IMT in pPE women in comparison to women who had uncomplicated pregnancies, selected from PubMed and EMBASE databases, were included. Studies evaluating women with previous history of early-onset (EO) or late-onset (LO) PE vs healthy controls were separately analyzed. Continuous data (CCA-IMT) were pooled as a standardized mean difference (SMD) comparing pPE group with healthy controls. The subtotal and overall SMDs of CCA-IMT were calculated using the random-effect model.

Results

The full-texts of 12 studies with 583 pPE women and 610 healthy controls were analyzed. The average time after delivery was 8.5 yrs (range 1.1–20 yrs). The average CCA-IMT was significantly increased in pPE women than healthy controls in five studies (41.7 % of total), whereas it was similar between the two study groups or surprisingly reduced in pPE women vs controls in more than half of studies (58.3 % of total). The effect of pPE on CCA-IMT was very small for the studies including women with previous LO-PE (subtotal SMD 0.067, 95 %CI −0.339,0.472, P = 0.75) and small for those analyzing women with previous EO-PE (subtotal SMD 0.250, 95 %CI-0.231,0.732, P = 0.31). Overall, the effect of pPE on CCA-IMT was small and not statistically significant (SMD 0.143, 95 %CI −0.167,0.453, P = 0.37). Substantial heterogeneity was detected for the included studies, with an overall I2 statistic value of 81 % (P < 0.001). Egger’s test for a regression intercept yielded a P-value of 0.58, indicating no publication bias. On meta-regression analysis, none of the moderators and/or potential confounders was significantly associated with effect modification (all P > 0.05).

Conclusions

Women with previous history of PE have an increased burden of cardiovascular risk factors, but do not appear to be affected by significant subclinical carotid atherosclerosis, up to 20 years postpartum.
背景:在过去的二十年中,有几项研究对既往有子痫前期(pPE)病史的妇女与无并发症妊娠妇女的颈总动脉(CCA)内膜中层厚度(IMT)进行了评估,但结果并不一致。本系统综述和荟萃分析旨在总结这些研究的主要发现,并研究 pPE 对 CCA-IMT 的总体影响:方法:从 PubMed 和 EMBASE 数据库中筛选出所有评估 pPE 妇女与无并发症妊娠妇女的 CCA-IMT 比较的研究。分别分析了评估既往有早发(EO)或晚发(LO)PE病史的女性与健康对照组的研究。将连续数据(CCA-IMT)汇总为 pPE 组与健康对照组的标准化平均差 (SMD)。采用随机效应模型计算 CCA-IMT 的小计和总 SMD:结果:分析了 12 项研究的全文,其中包括 583 名 pPE 妇女和 610 名健康对照组。平均产后时间为 8.5 年(1.1-20 年不等)。在五项研究(占总数的 41.7%)中,pPE 妇女的平均 CCA-IMT 比健康对照组明显增加,而在一半以上的研究(占总数的 58.3%)中,pPE 妇女的平均 CCA-IMT 与健康对照组相似或出人意料地减少。在包括曾患 LO-PE 的女性的研究中,pPE 对 CCA-IMT 的影响非常小(SMD 小计 0.067,95 %CI -0.339,0.472,P = 0.75),而在分析曾患 EO-PE 的女性的研究中,pPE 对 CCA-IMT 的影响也很小(SMD 小计 0.250,95 %CI-0.231,0.732, P = 0.31)。总体而言,PPE 对 CCA-IMT 的影响较小,且无统计学意义(SMD 0.143,95 %CI -0.167,0.453,P = 0.37)。在纳入的研究中发现了大量异质性,总体I2统计值为81%(P 0.05):结论:曾有过 PE 病史的妇女的心血管风险因素负担会增加,但在产后 20 年内似乎不会受到明显的亚临床颈动脉粥样硬化的影响。

Clinical Practice Guidelines (CPGs) have an indispensable role in guiding the selection of treatments for menopause. Variations in guidelines can impact treatments and health outcomes. The aim of this study was to assess CPGs on hormone replacement therapy (HRT) for menopause, systematically reviewing their quality and compiling recommendations for HRT usage.
Embase, Scopus, MedLine, Geneva Foundation for Medical Education and Research databases were searched to identify relevant publications. CPGs published in English language, focusing specifically on HRT for menopause were included in the analysis. Four reviewers assessed the quality of the included CPGs using the Appraisal of Guidelines for Research & Evaluation II (AGREE II) instrument and compiled congruent as well as contradictory recommendations.
Nine guidelines met the inclusion criteria. The National Institute for Health and Care Excellence (NICE), the Endocrine Society and The Association of the Scientific Medical Societies guidelines were deemed to have the highest quality and are recommended without modifications. Out of 300+ extracted recommendations, merely 17 showed consistency, overlapping in at least two CPGs. The recommendations were categorized into three domains: treatment considerations, impact of HRT on non-reproductive organ systems, and the associations of HRT with cancer. The included CPGs exhibited the highest scores in the “Clarity of presentation” and “Scope and purpose” AGREE II domains.
This study found variation in recommendations and quality of CPG on HRT for menopause. Notably, only a small fraction of recommendations showed consistency across guidelines, highlighting the variability in HRT management. Efforts to improve the quality of CPGs in this area are essential to optimize patient care and outcomes in menopausal women receiving HRT.
临床实践指南(CPG)在指导更年期治疗方法的选择方面发挥着不可或缺的作用。指南的不同会影响治疗和健康结果。本研究旨在评估有关更年期激素替代疗法(HRT)的临床实践指南,系统地审查其质量并汇编有关使用 HRT 的建议。研究人员检索了 Embase、Scopus、MedLine 和日内瓦医学教育与研究基金会数据库,以确定相关出版物。以英语发表的、专门针对更年期的 HRT 的 CPG 纳入了分析范围。四位评审员使用研究与评估指南评估 II (AGREE II) 工具对纳入的 CPGs 进行了质量评估,并汇编了一致和矛盾的建议。九项指南符合纳入标准。美国国家健康与护理卓越研究所(NICE)、内分泌学会和科学医学协会的指南被认为质量最高,无需修改即可推荐使用。在提取的 300 多条建议中,仅有 17 条具有一致性,至少在两条 CPG 中重叠。这些建议分为三个领域:治疗注意事项、HRT 对非生殖器官系统的影响以及 HRT 与癌症的关系。纳入的 CPG 在 "表述清晰度 "和 "范围与目的 "AGREE II 领域中得分最高。这项研究发现,有关更年期激素治疗的 CPG 在建议和质量方面存在差异。值得注意的是,只有一小部分建议在不同指南中表现出一致性,这凸显了更年期激素治疗管理的差异性。努力提高该领域 CPG 的质量对于优化接受 HRT 的更年期妇女的患者护理和治疗效果至关重要。

Pregnancy with history of peripartum cardiomyopathy, residual left ventricular dysfunction is associated with high maternal and neonatal morbidity and mortality. Remote monitoring of pulmonary artery pressure and vital signs have been utilized in clinical settings to manage select patients with heart failure. However, data of using these systems to aid clinical management in pregnancy remains unexplored. To our knowledge, this case report is the first to describe successful management of a 31-year-old pregnant patient with history of peripartum cardiomyopathy, severe left ventricular dysfunction and pulmonary embolism using the CardioMEMS device throughout pregnancy. CardioMEMS system provided continuous remote hemodynamic monitoring during pregnancy, aiding in the management of this high-risk patient. The device’s ability to provide real-time data allowed for correlation between symptoms and hemodynamics, allowing for prompt adjustments in treatment, ensuring stability throughout the pregnancy. This patient was able to avoid hospital admissions and successfully deliver a healthy baby via vaginal delivery. This report highlights the potential benefits of utilizing CardioMEMS in clinical management of such patients.
妊娠合并围产期心肌病、残留左心室功能障碍与孕产妇和新生儿的高发病率和死亡率有关。肺动脉压力和生命体征的远程监测已被用于临床治疗部分心衰患者。然而,将这些系统用于辅助妊娠期临床管理的数据仍有待探索。据我们所知,本病例报告首次描述了在整个孕期使用 CardioMEMS 设备成功治疗一名 31 岁的妊娠期患者的情况,该患者有围产期心肌病、严重左心室功能障碍和肺栓塞病史。CardioMEMS 系统可在妊娠期间提供连续的远程血液动力学监测,帮助管理这名高危患者。该设备能够提供实时数据,使症状与血液动力学相关联,从而能够及时调整治疗方案,确保整个孕期的病情稳定。这名患者避免了入院治疗,并通过阴道分娩顺利产下一名健康婴儿。这份报告强调了利用 CardioMEMS 对此类患者进行临床管理的潜在益处。

Introduction

In recent years, caesarean section (CS) rate has risen worldwide. Complications associated with CS scars have risen too, such as scar dehiscences and uterine ruptures. Uterine healing is a complex phenomenon still poorly understood. The aim of this study is to carry out a comparative histological analysis of healthy and scarred uterus.

Material and methods

Women who underwent hysterectomy for benign pathology were included prospectively and divided into two groups: previous CS (group 1) versus control (group 2). Hysterectomy specimen were analyzed histologically and immunohistochemically.

Results

Sixty women were included: 30 women per group. In group 1, only 19 women could be analyzed. Median total thickness at the thinnest site of the scar is significantly thinner (4.34 mm; IQR [2.76–9.45]) than that of adjacent healthy isthmus (12.70 mm; IQR [10.45–14.95]) (p < 0.001). It is also thinner than in group 2 (13.45 mm; IQR [11.03–16.90]) (p < 0.001). Median myometrial thickness within the scar in group 1 was also thinner (1.14 mm; IQR [0.30–2.69]) than that of the adjacent healthy isthmus (8.90 mm; IQR [8.18–10.08]) (p < 0.001) and that in group 2 (10.00 mm; IQR [8.38–13.35]) (p < 0.001). There was a significant increase in fibrosis in the scar (55.01 %; IQR [35.71–63.46]) compared with adjacent tissue (17.41 %; IQR [15.08–24.78]) (p < 0.001) and with healthy uterus (33.91 %; IQR [18.93–46.53]) (p = 0.006).

Conclusion

In uterus with previous CS scar, total thickness of the wall and thickness of the myometrium are reduced and proportion of fibrosis is significantly increased. This study shows that the thickness of the wall remains reduced in scarred uterus, even very long after CS. Further studies are currently in progress to understand its pathophysiology within the uterus using animal models.
导言近年来,剖腹产(CS)率在全球范围内不断上升。与剖腹产疤痕相关的并发症也在增加,如疤痕裂开和子宫破裂。子宫愈合是一个复杂的现象,人们对它的了解还很少。本研究旨在对健康子宫和疤痕子宫进行组织学对比分析。材料和方法前瞻性地纳入了因良性病变而接受子宫切除术的女性,并将其分为两组:既往 CS(第 1 组)和对照组(第 2 组)。对子宫切除标本进行组织学和免疫组化分析:每组 30 人。在第 1 组中,只有 19 名妇女可以进行分析。疤痕最薄处的中位总厚度(4.34 毫米;IQR [2.76-9.45])明显薄于邻近的健康峡部(12.70 毫米;IQR [10.45-14.95])(p <0.001)。它也比第 2 组(13.45 毫米;IQR [11.03-16.90])薄(p <0.001)。与邻近健康峡部(8.90 毫米;IQR [8.18-10.08])(p <0.001)和第 2 组(10.00 毫米;IQR [8.38-13.35])(p <0.001)相比,第 1 组瘢痕内子宫肌层厚度中值(1.14 毫米;IQR [0.30-2.69])也较薄。与邻近组织(17.41%;IQR [15.08-24.78])(p < 0.001)和健康子宫(33.91%;IQR [18.93-46.53])(p = 0.006)相比,瘢痕处的纤维化程度明显增加(55.01%;IQR [35.71-63.46])。这项研究表明,即使在 CS 后很长时间,瘢痕子宫壁的厚度仍然会减少。目前正在利用动物模型开展进一步研究,以了解其在子宫内的病理生理学。

Methods

The protocol is registered with INPLASY (registration number is INPLASY202460075). Computer retrieval PubMed, the Cochrane Library, Embase database related (mifepristone group) compared to placebo and mifepristone or conventional treatment (control group) in the treatment of uterine fibroids randomized controlled trial (RCT), retrieve the time limit for a Library to in October 2023, Refer to the Cochrane faced the quality evaluation of the literature of included in the 6.0 and uses the RevMan 5.4.1 software Meta-analysis and sensitivity analysis.

Results

There were 18 studies with a total of 2066 patients as participants. A meta-analysis found that the patients in the mifepristone group had lower uterine volume or uterine fibroid volume than the control group, with a statistically significant difference. Mifepristone treatment for 3 months uterine volume smaller is better than 6 months the difference is statistically significant. Compared with the control group, mifepristone can improve pelvic pain, pelvic pressure, bladder pressure, urinary symptoms, lower back pain, dyspareunia, rectal pain, menorrhagia, hypermenorrhea, and other clinical symptoms. The Mifepristone group had hot flashes, endometrium thickness increases, the incidence of hepatic transaminases associated is significantly higher than the control group, the patients in the 10 mg/d mifepristone group had endometrial thickness that was greater than those in the 5 mg/d mifepristone group.

Conclusions

Mifepristone reduces fibroid volume and improves clinical symptoms, and 5 mg/day of mifepristone for three months may be the optimal clinical regimen.

Objectives

Maternal cigarette smoking during pregnancy is associated with adverse health outcomes for the mother and her fetus in utero. A high prevalence of smoking during pregnancy is reported within an Irish obstetric population. However, there are no recent Irish data regarding change in smoking rates over time, or factors associated with declining smoking prevalence. Therefore, the objectives of this study were: 1. To investigate smoking patterns in pregnancy among an Irish obstetric population, 2. To identify trends over time, and 3. To evaluate associated demographic factors.

Study Design

The data for this study were obtained from EuroKing, a computerised obstetric database, to which data had been entered prospectively during the 8-year period between January 2015 and December 2022 at Galway University Hospital, Ireland. A total of 22,673 deliveries were recorded during this time period. Complete information regarding the mother’s smoking history was available for 19,247 women at the time of antenatal booking, and again at delivery. Statistical analyses was performed using GraphPad Prism (version 10.1.2). Chi-square test for proportions and trend were used to assess differences between groups.

Results

Rates of smoking during pregnancy declined over the duration of the study. The percentage of mothers who smoked during pregnancy declined from 8.3 % in 2015 to 6.0 % in 2022 (P = 0.007). The greatest reduction in smoking was observed among those aged 21 to 30 years, from 15.3 % in 2015 to 10.1 % in 2022 (P < 0.001). There was no significant decline in smoking within the other age groups. There was an overall reduction in the rate of smoking from the time of antenatal booking to delivery of 31.9 %. Increasing maternal age was associated with lower rates of smoking (P < 0.001). Increasing parity was associated with higher rates of smoking (P < 0.001). Smoking rates were highest in the White Irish Traveller ethnic group, at 40.3 % across the 8-year study period. Breastfeeding rates were lower in smokers versus non-smokers (P < 0.001).

Conclusion

This study indicates that the rate of maternal smoking during pregnancy in Ireland is approximately 6%, which is less than previously reported. A significant proportion of women who smoked at the time of antenatal booking have ceased smoking by the time of delivery. Overall there was a decline in maternal smoking over the duration of the study. However, high rates of smoking were associated with certain sociodemographic characteristics, including younger maternal age, increasing parity and White Irish Traveller background.
目的:母亲在怀孕期间吸烟会对母亲及其宫内胎儿的健康造成不良影响。据报道,在爱尔兰的产科人群中,孕期吸烟的比例很高。然而,爱尔兰没有关于吸烟率随时间变化的最新数据,也没有与吸烟率下降相关的因素。因此,本研究的目标是1.调查爱尔兰产科人群在怀孕期间的吸烟模式;2. 确定随时间变化的趋势;3.研究设计:本研究的数据来自爱尔兰戈尔韦大学医院的计算机化产科数据库 EuroKing,该数据库在 2015 年 1 月至 2022 年 12 月的 8 年间进行了前瞻性数据输入。在此期间,共记录了 22,673 例分娩。19247名产妇在产前预约时和分娩时都提供了有关母亲吸烟史的完整信息。统计分析使用 GraphPad Prism(10.1.2 版)进行。对比例和趋势的卡方检验用于评估组间差异:在研究期间,孕期吸烟率有所下降。孕期吸烟的母亲比例从2015年的8.3%降至2022年的6.0%(P = 0.007)。年龄在 21 至 30 岁之间的母亲吸烟率降幅最大,从 2015 年的 15.3% 降至 2022 年的 10.1%(P 结论:吸烟母亲的比例从 2015 年的 8.3% 降至 2022 年的 6.0%(P = 0.007):这项研究表明,爱尔兰孕产妇在怀孕期间吸烟的比例约为 6%,低于之前的报道。相当一部分在产前预约时吸烟的妇女在分娩时已停止吸烟。总体而言,在研究期间,孕产妇吸烟率有所下降。然而,高吸烟率与某些社会人口特征有关,包括产妇年龄较小、胎次增加和爱尔兰白人游民背景。

Objective

To evaluate whether a daily dose of low-dose aspirin (LDA) can prevent hypertensive disorders of pregnancy (HDP), including preeclampsia, among pregnant women in a South African cohort, and to assess its impact on related maternal and fetal outcomes, such as preterm birth and neonatal complications.

Study design

This single-center, open-label, parallel-group randomized controlled trial (RCT) was conducted at a regional hospital in Durban, KwaZulu-Natal, South Africa, from May 2021 to March 2024. A total of 423 pregnant women, aged 18 years or older with singleton pregnancies between 12 and 20 weeks of gestation, were randomized to receive either 162 mg of LDA daily or standard care. The primary outcome was the incidence of HDP, while secondary outcomes included early-onset preeclampsia (EOPE), preterm birth, low birth weight (LBW), and neonatal death. Data analysis used relative risk (RR) and 95 % confidence intervals (CIs).

Results

Of the 423 women, 209 were in the LDA group and 214 in the control group. The incidence of HDP was significantly lower in the LDA group (6.2 % vs. 25.2 %; RR = 0.25, 95 % CI [0.14–0.44], p < 0.001), corresponding to a 75 % reduction in HDP risk, with an absolute risk reduction (ARR) of 19 % and a number needed to treat (NNT) of 5.3. EOPE was reduced (2.4 % vs. 14.0 %; RR = 0.17, 95 % CI [0.07–0.41], p < 0.001), as was preterm birth (6.7 % vs. 26.2 %; RR = 0.26, 95 % CI [0.15–0.45], p < 0.001). There were no significant differences for LBW or neonatal death. Sensitivity analysis confirmed the importance of initiating LDA before 16 weeks, showing continued reductions in HDP incidence with early initiation.

Conclusion

LDA significantly reduces the risk of HDP, EOPE, and preterm birth, particularly when initiated before 16 weeks of gestation. These findings support the use of LDA for preventing hypertensive disorders of pregnancy in low-resource settings and underscore the value of early intervention for improved maternal and fetal outcomes.
目的评估每日服用低剂量阿司匹林(LDA)能否预防南非孕妇的妊娠高血压疾病(HDP),包括子痫前期,并评估其对相关孕产妇和胎儿结局(如早产和新生儿并发症)的影响。研究设计这项单中心、开放标签、平行组随机对照试验(RCT)于2021年5月至2024年3月在南非夸祖鲁-纳塔尔省德班市的一家地区医院进行。共有 423 名年龄在 18 岁或以上、妊娠 12-20 周的单胎孕妇被随机分配到每天服用 162 毫克 LDA 或接受标准护理。主要结果是HDP的发生率,次要结果包括早发子痫前期(EOPE)、早产、低出生体重(LBW)和新生儿死亡。数据分析采用相对风险(RR)和95%置信区间(CI)。LDA组的HDP发生率明显降低(6.2% vs. 25.2%;RR = 0.25,95 % CI [0.14-0.44],p <0.001),相当于HDP风险降低了75%,绝对风险降低率(ARR)为19%,治疗需要量(NNT)为5.3。EOPE降低了(2.4% vs. 14.0%;RR = 0.17,95 % CI [0.07-0.41],p <0.001),早产也降低了(6.7% vs. 26.2%;RR = 0.26,95 % CI [0.15-0.45],p <0.001)。在低体重儿和新生儿死亡方面没有明显差异。敏感性分析证实了在16周前开始LDA的重要性,显示早期开始LDA可持续降低HDP发生率。这些研究结果支持在低资源环境中使用 LDA 预防妊娠期高血压疾病,并强调了早期干预对改善孕产妇和胎儿预后的价值。
