Acute Sheehan syndrome following massive postpartum hemorrhage due to vulvar hematoma 外阴血肿导致产后大出血后的急性希恩综合征
Pub Date : 2024-09-18 DOI: 10.1016/j.xagr.2024.100399
Acute Sheehan syndrome appearing within 6 weeks postpartum is a rare form of hypopituitarism caused by postpartum hemorrhage. A 37-year-old Japanese woman experienced a vulvar hematoma after spontaneous labor at 40 weeks gestation, leading to massive postpartum hemorrhage (estimated total blood loss of 3,000 mL). Despite successful cesarean delivery and hematoma drainage, she presented 28 days postpartum with anorexia, fatigue, and hyponatremia after initial recovery. MRI revealed a swollen pituitary gland with subacute hemorrhage, confirming the diagnosis. Hormonal replacement therapy with levothyroxine, hydrocortisone, estrogen, and progesterone was initiated. This is the first reported case of acute Sheehan syndrome following a vulvar hematoma, a condition typically not considered a risk factor for this syndrome. The case highlights the importance of considering rare complications like acute Sheehan syndrome in patients with massive postpartum hemorrhage, even when the pathogenesis is clinically common, such as vulvar hematomas.
产后 6 周内出现的急性希恩综合征是由产后出血引起的一种罕见的垂体功能减退症。一名 37 岁的日本妇女在妊娠 40 周时自然分娩后出现外阴血肿,导致大量产后出血(估计总失血量为 3 000 毫升)。尽管成功进行了剖宫产和血肿引流,但她在产后 28 天出现厌食、乏力和低钠血症。核磁共振成像显示她的垂体肿大并伴有亚急性出血,从而确诊了她的病症。患者开始接受左甲状腺素、氢化可的松、雌激素和黄体酮等激素替代治疗。这是首例报告的外阴血肿后急性希恩综合征病例,而外阴血肿通常不被认为是该综合征的危险因素。该病例强调了考虑产后大出血患者的罕见并发症(如急性希恩综合征)的重要性,即使发病机制在临床上很常见,如外阴血肿。

Thoughts and opinions about fertility preservation and family building from the transgender community—an interview-based approach 变性人群体对生育力保存和家庭建设的想法和意见--基于访谈的方法
Pub Date : 2024-09-18 DOI: 10.1016/j.xagr.2024.100398

Background

When considering the significant prevalence of transgender and gender nonconforming individuals, it is imperative that physicians work to understand the unique needs of this population including paths to family building and fertility preservation.

Objective

To understand the thoughts and opinions about fertility preservation and family building within the transgender community.

Study design

Survey-based study and qualitative study at a single, large hospital-affiliated fertility center. A 16-question survey followed by a 30-minute virtual interview was utilized. Forty-three participants completed the survey and were used for quantitative analysis, and 40 audio files were used for qualitative analysis.

Results

The average age of participants was 27.0±7.3 years old. The majority of participants were assigned female at birth (70.7%); however, most participants’ gender identities were transgender (54.8%) or nonbinary (47.6%). The average age at which participants realized they were transgender and disclosed their identity to a friend, or partner, was 16.2±7.0 (range 3–30) and 20.1±5.6 (range 11–33), respectively. The average age that participants disclosed their gender identity to their parents, siblings, or other family was 22.4±5.9 (range 12–35). Five categories were utilized to summarize the experiences and opinions of the participants: family building and parenthood goals, influences of family background/partner on parenthood goals, awareness and knowledge about fertility preservation, barrier to family building, and recommended healthcare provider communication and education. Sixteen participants (40.0%, n/N=16/40) were interested in having children in the future, 18 (45.0%, n/N=18/40) were unsure/dependent on their partner, and 6 (15.0%, n/N=6/40) were not interested in having children. Of those interested in having children (n/N=16/40), the majority wished to utilize adoption to build their family (68.8%, n/N=11/16). Nine participants (22.5%, n/N=9/40) reported that fertility preservation was never discussed. Most participants agreed that gender dysphoria, cost, inadequate counseling, and improvements in healthcare knowledge about transgender individuals were key influences on their opinions about pursuing fertility preservation or parenthood.

Conclusion

Transgender individuals want to build families, and the majority consider adoption the preferred method. There are still transgender individuals who are not counseled about fertility preservation. It is imperative the healthcare system continues to improve the education of healthcare providers about management and care of transgender individuals to provide the best care for this vulnerable population.
背景当考虑到变性人和性别不符者的大量存在时,医生必须努力了解这一人群的独特需求,包括建立家庭和保留生育能力的途径。研究设计在一家大型医院附属生殖中心进行的基于调查的研究和定性研究。研究采用了 16 个问题的问卷调查和 30 分钟的虚拟访谈。43名参与者完成了调查并被用于定量分析,40份音频文件被用于定性分析。大多数参与者在出生时被分配为女性(70.7%);然而,大多数参与者的性别认同是跨性别(54.8%)或非二元(47.6%)。参与者意识到自己是变性人并向朋友或伴侣公开自己身份的平均年龄分别为 16.2±7.0(3-30 岁)和 20.1±5.6(11-33 岁)。参与者向父母、兄弟姐妹或其他家人透露自己性别认同的平均年龄为 22.4±5.9(范围 12-35)岁。参与者的经验和观点分为五个类别:建立家庭和生育目标、家庭背景/伴侣对生育目标的影响、对生育力保存的认识和知识、建立家庭的障碍以及建议医疗服务提供者进行的沟通和教育。16名参与者(40.0%,n/N=16/40)对将来生育孩子感兴趣,18名参与者(45.0%,n/N=18/40)不确定/依赖其伴侣,6名参与者(15.0%,n/N=6/40)对生育孩子不感兴趣。在有意生育的参与者(n/N=16/40)中,大多数希望通过领养来建立家庭(68.8%,n/N=11/16)。九名参与者(22.5%,n/N=9/40)表示从未讨论过保留生育力的问题。大多数参与者都认为,性别焦虑症、费用、咨询不足以及对变性人的医疗保健知识的改善是影响他们对保留生育力或生儿育女的看法的关键因素。但仍有一些变性人没有接受过有关保留生育力的咨询。医疗系统必须继续加强对医疗服务提供者的教育,使其了解变性人的管理和护理,从而为这一弱势群体提供最佳护理。

The role of the RHOA/ROCK pathway in the regulation of myometrial stages throughout pregnancy RHOA/ROCK 通路在整个孕期调节子宫肌层阶段中的作用
Pub Date : 2024-09-18 DOI: 10.1016/j.xagr.2024.100394

Background

Controlling uterine contractile activity is essential to regulate the duration of pregnancy. During most of the pregnancy, the uterus does not contract (i.e., myometrial quiescence). The myometrium recovers its contractile phenotype at around 36 weeks (i.e., myometrial activation) through several mechanisms. The RHOA/ROCK pathway plays a vital role in facilitating muscular contractions by calcium sensitization in humans. Yet, the role of this pathway during different myometrial stages, including quiescence, has not been elucidated.

Objective

we aimed to study the role of the RHOA/ROCK pathway in the regulation of the different myometrial stages throughout pregnancy. Specifically, we hypothesized that the inhibition of the components of the RHOA/ROCK pathway play an important role in maintaining uterine quiescence.

Study design

Myometrial samples were obtained from pregnant individuals who underwent cesarean section. Pregnant individuals who delivered preterm without labor (myometrial quiescence), preterm with labor (nonphysiological myometrial stimulation), term not in labor (activation), and term in labor (physiological myometrial stimulation) were included. The mRNA and protein expression of RHOA, ROCK I, ROCK II, RND1-3, and ROCK activity through pMYTP1 were evaluated.

Results

We found that the human myometrium constitutively expressed RHOA/ROCK pathway components throughout pregnancy. No changes in the components of the RHOA/ROCK pathway were found during quiescence. Moreover, the RHOA protein and ROCK activity increased in the myometrium during labor, supporting the hypothesis that this pathway participates in maintaining the contractile activity of the myometrium. This study provides insight into the role of the RHOA/ROCK pathway in controlling myometrial contractile activity during pregnancy.
背景控制子宫收缩活动对调节妊娠持续时间至关重要。在妊娠的大部分时间里,子宫不收缩(即子宫肌静止)。子宫肌层在 36 周左右通过几种机制恢复其收缩表型(即子宫肌层激活)。RHOA/ROCK 通路在通过钙敏化促进人体肌肉收缩方面发挥着重要作用。我们的目的是研究 RHOA/ROCK 通路在整个孕期不同子宫肌层阶段的调控作用。具体而言,我们假设抑制 RHOA/ROCK 通路的成分在维持子宫静止中发挥重要作用。研究设计从接受剖宫产的孕妇身上获取子宫样本。研究对象包括未分娩的早产儿(子宫肌层静止)、分娩的早产儿(非生理性子宫肌层刺激)、未分娩的足月儿(激活)和分娩的足月儿(生理性子宫肌层刺激)。评估了 RHOA、ROCK I、ROCK II、RND1-3 的 mRNA 和蛋白表达,以及通过 pMYTP1 表达的 ROCK 活性。在静止期,RHOA/ROCK 通路成分没有发生变化。此外,分娩时子宫肌层中的 RHOA 蛋白和 ROCK 活性增加,支持了这一途径参与维持子宫肌层收缩活性的假设。这项研究有助于深入了解 RHOA/ROCK 通路在妊娠期控制子宫肌收缩活动中的作用。

Guillain-Barré syndrome in pregnancy: a case report and review of the literature 妊娠期格林-巴利综合征:病例报告和文献综述
Pub Date : 2024-09-14 DOI: 10.1016/j.xagr.2024.100396
Guillain-Barré syndrome represents a heterogeneous group of immune-mediated peripheral neuropathies that are characterized by various clinical manifestations. Reporting this clinical case emphasizes the rarity of Guillain-Barré syndrome, the diagnostic challenges faced by healthcare providers, and the risk of delayed diagnosis for both the mother and fetus. A 34-year-old pregnant woman at 33 weeks of gestation presented to the inpatient ward complaining of paresthesia in the lower and upper limbs, muscle pain, balance disturbances, moderate headache, nausea and vertigo, general weakness, and pronounced fatigue. The patient had experienced an acute viral respiratory infection 4 weeks before presenting to the hospital. The patient was admitted to the intensive care unit with a preliminary diagnosis of acute viral respiratory infection and nasopharyngitis. The patient's condition worsened dynamically, manifesting bulbar syndrome (swallowing problems), paresthesia of the anterior abdominal wall, reduced perception of fetal movements, numbness of the tongue, and low fever (37.2°C). A diagnosis of acute inflammatory demyelinating polyradiculopathy (Guillain-Barré syndrome) was established. Despite treatment, the neurologic symptoms worsened. The paravertebral radicular type pains were difficult to manage with administered analgesic therapy, and there was a progression of the bulbar syndrome. Treatment with intravenous immunoglobulin was initiated. Consequently, it was recommended by the multidisciplinary council to perform an emergency cesarean delivery, in the interest of the mother and fetus. Guillain-Barré syndrome is a rare condition that occurs during pregnancy and requires thorough evaluation, prompt multidisciplinary assessment, and individualized management of delivery to improve maternal and fetal prognosis.
吉兰-巴雷综合征(Guillain-Barré syndrome)是一组免疫介导的周围神经病,临床表现多种多样。报告这一临床病例强调了吉兰-巴雷综合征的罕见性、医疗服务提供者面临的诊断挑战以及母亲和胎儿被延误诊断的风险。一名 34 岁的孕妇在妊娠 33 周时来到住院病房,主诉上下肢麻痹、肌肉疼痛、平衡障碍、中度头痛、恶心和眩晕、全身乏力和明显疲倦。患者入院前四周曾经历过一次急性病毒性呼吸道感染。患者被送入重症监护室,初步诊断为急性病毒性呼吸道感染和鼻咽炎。患者的病情不断恶化,出现了球部综合征(吞咽困难)、前腹壁麻痹、胎动感减弱、舌头麻木和低烧(37.2°C)。最终确诊为急性炎症性脱髓鞘多发性神经病(吉兰-巴雷综合征)。尽管进行了治疗,但神经系统症状仍然恶化。椎旁神经根型疼痛很难通过镇痛治疗来控制,球部综合征也在恶化。患者开始接受静脉注射免疫球蛋白治疗。因此,为了母亲和胎儿的利益,多学科委员会建议进行紧急剖宫产。吉兰-巴雷综合征是一种罕见的妊娠期疾病,需要进行全面评估、及时的多学科评估和个性化的分娩管理,以改善母体和胎儿的预后。

Using machine learning to predict the risk of developing hypertensive disorders of pregnancy using a contemporary nulliparous cohort 利用机器学习预测妊娠期高血压疾病的发病风险
Pub Date : 2024-08-22 DOI: 10.1016/j.xagr.2024.100386

Background

Hypertensive disorders of pregnancy (HDP) are significant drivers of maternal and neonatal morbidity and mortality. Current management strategies include early identification and initiation of risk mitigating interventions facilitated by a rules-based checklist. Advanced analytic techniques, such as machine learning, can potentially offer improved and refined predictive capabilities.

Objective

To develop and internally validate a machine learning prediction model for hypertensive disorders of pregnancy (HDP) when initiating prenatal care.

Study Design

We developed a prediction model using data from the prospective multisite cohort Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be (nuMoM2b) among low-risk individuals without a prior history of aspirin utilization for preeclampsia prevention. The primary outcome was the development of HDP. Random forest modeling was utilized to develop predictive models. Recursive feature elimination (RFE) was employed to create a reduced model for each outcome. Area under the curve (AUC), 95% confidence intervals (CI), and calibration curves were utilized to assess discrimination and accuracy. Sensitivity analyses were conducted to compare the sensitivity and specificity of the reduced model compared to existing risk factor-based algorithms.

Results

Of 9,124 assessed low risk nulliparous individuals, 21% (n=1,927) developed HDP. The prediction model for HDP had satisfactory discrimination with an AUC of 0.73 (95% CI: 0.70, 0.75). After RFE, a parsimonious reduced model with 30 features was created with an AUC of 0.71 (95% CI: 0.68, 0.74). Variables included in the model after RFE included body mass index at the first study visit, pre-pregnancy weight, first trimester complete blood count results, and maximum systolic blood pressure at the first visit. Calibration curves for all models revealed relatively stable agreement between predicted and observed probabilities. Sensitivity analysis noted superior sensitivity (AUC 0.80 vs 0.65) and specificity (0.65 vs 0.53) of the model compared to traditional risk factor-based algorithms.

Conclusion

In cohort of low-risk nulliparous pregnant individuals, a prediction model may accurately predict HDP diagnosis at the time of initiating prenatal care and aid employment of close interval monitoring and prophylactic measures earlier in pregnancy.
背景妊娠高血压疾病(HDP)是导致孕产妇和新生儿发病和死亡的重要因素。目前的管理策略包括通过基于规则的核对表进行早期识别和启动降低风险的干预措施。研究设计我们利用前瞻性多站点队列无胎儿妊娠结局研究(Nulliparous Pregnancy Outcomes Study)的数据开发了一个预测模型:我们利用前瞻性多站点队列 "无胎盘妊娠结局研究:待产母亲监测"(nuMoM2b)中的数据开发了预测模型。主要结果是出现 HDP。随机森林模型用于开发预测模型。采用递归特征剔除法(RFE)为每个结果创建一个简化模型。利用曲线下面积 (AUC)、95% 置信区间 (CI) 和校准曲线来评估区分度和准确性。进行了敏感性分析,以比较简化模型与现有基于风险因素算法的敏感性和特异性。结果 在 9124 名接受评估的低风险无子宫者中,21%(n=1927)发展为 HDP。HDP 预测模型的分辨能力令人满意,AUC 为 0.73 (95% CI: 0.70, 0.75)。RFE 后,建立了一个包含 30 个特征的简化模型,其 AUC 为 0.71(95% CI:0.68,0.74)。RFE 后的模型所包含的变量包括首次就诊时的体重指数、孕前体重、孕期前三个月的全血细胞计数结果以及首次就诊时的最大收缩压。所有模型的校准曲线显示,预测概率和观察概率之间的一致性相对稳定。灵敏度分析表明,与传统的基于风险因素的算法相比,该模型的灵敏度(AUC 0.80 vs 0.65)和特异性(0.65 vs 0.53)更优。

Background

Induction of labor (IOL) is an increasingly common intervention, but experiences and preferences of induction methods are under-researched particularly in low -and middle-income countries. Understanding these perspectives is important to improve the childbirth experience.

Objective

To explore the experiences and preferences of IOL methods for women, clinicians, and researchers in the “Misoprostol or Oxytocin for Labour Induction” (MOLI) study.

Study Design

This qualitative study was based in two government hospitals in the city of Nagpur, India—one tertiary referral hospital and one women's hospital. Fifty-three semi-structured interviews with women before and after induction (between days 1 and 5 postnatal), with women recruited to the “Misoprostol or Oxytocin for Labour Induction (MOLI)” randomized controlled trial (NCT03749902). Eight focus group discussions with doctors, nurses, and trial research assistants before and during trial delivery were conducted. Thematic analysis was conducted using the Framework approach.

Results

Four themes emerged: (1) IOL methods, (2) impact of the study, (3) IOL and childbirth as one small part of the wider experiences in life, and (4) key moments in the childbirth experience. For women, the safety of their baby was more important than any IOL method. Clinicians had apprehensions over misoprostol use which could affect protocol implementation; they reported that changing perception is difficult as usual practice feels “comfortable.” Women wanted to share their experiences and reported key moments during childbirth including vaginal examinations, “trying for normal,” bearing the pain, waiting, and relationships with staff.

Conclusion

Women did not have a strong preference for the IOL method and viewed childbirth positively when maternal and neonatal outcomes were good. Labor pain, vaginal examinations, a normal birth, and interactions with staff impacted women's experiences.

背景引产(IOL)是一种越来越常见的干预措施,但对引产方法的体验和偏好研究不足,尤其是在中低收入国家。研究设计这项定性研究在印度那格浦尔市的两家政府医院进行,其中一家是三级转诊医院,另一家是妇女医院。对参加 "米索前列醇或催产素引产(MOLI)"随机对照试验(NCT03749902)的妇女在引产前后(产后第 1 至 5 天)进行了 53 次半结构式访谈。在试验分娩前和分娩过程中,与医生、护士和试验研究助理进行了八次焦点小组讨论。结果出现了四个主题:(1) IOL 方法;(2) 研究的影响;(3) IOL 和分娩是人生更广泛经历中的一小部分;(4) 分娩经历中的关键时刻。对妇女来说,婴儿的安全比任何人工晶体植入方法都重要。临床医生对使用米索前列醇有顾虑,这可能会影响方案的实施;他们报告说,改变观念很难,因为通常的做法让人感觉 "舒服"。妇女希望分享她们的经验,并报告了分娩过程中的关键时刻,包括阴道检查、"尝试正常"、忍受疼痛、等待以及与工作人员的关系。分娩疼痛、阴道检查、正常分娩以及与医护人员的互动影响着产妇的体验。

Based on the results of the OGTT, these GDM cases were classified into 7 subtypes, and the composition ratio of each subtype and their maternal and neonatal outcomes were analyzed. Innovatively, we proposed to categorize GDM-HR (characterized by elevated fasting blood glucose [FBG] levels, including T0, T0+1, T0+2, and T0+1+2) and low-risk GDM (GDM-LR, without elevated FBG, including T1, T2, and T1+2) and compared the maternal and neonatal outcomes between the two subtypes.</p></div><div><h3>Results</h3><p>(1) In this cohort of 3268 GDM cases, the composition ratios of the 7 GDM subtypes were as follows: T0 (7.9%, <em>n</em>=260), T1 (24.2%, <em>n</em>=791), T2 (27.4%, <em>n</em>=897), T0+1 (5.4%, <em>n</em>=175), T0+2 (1.7%, <em>n</em>=56), T1+2 (26.2%, <em>n</em>=855), and T0+1+2 (7.2%, <em>n</em>=234).

背景妊娠期糖尿病(GDM)可导致母婴各种不良妊娠结局,包括妊娠高血压、胎膜早破、早产、巨大儿、胎龄巨大儿(LGA)和新生儿低血糖。以往的研究主要关注 GDM 对孕产妇和新生儿不良结局的总体风险,但专门研究口服葡萄糖耐量试验(OGTT)异常结果的不同模式与孕产妇和新生儿不良结局之间关系的研究还很有限。研究目的本研究旨在分析不同OGTT模式的GDM产妇的孕产妇和新生儿结局,并探索一种新的分类方法,能够根据OGTT结果将GDM分为高危亚型(GDM-HR)和低危亚型。研究设计我们在浙江大学医学院附属女子医院开展了一项回顾性队列研究,时间跨度为2015年11月1日至2018年4月30日。研究期间,共纳入 3268 例 GDM 患者。根据 OGTT 的结果,这些 GDM 病例被分为 7 个亚型,并分析了各亚型的构成比例及其孕产妇和新生儿结局。我们创新性地提出了GDM-HR(以空腹血糖[FBG]水平升高为特征,包括T0、T0+1、T0+2和T0+1+2)和低风险GDM(GDM-LR,无FBG升高,包括T1、T2和T1+2)的分类,并比较了两种亚型的孕产妇和新生儿结局。结果(1) 在这组3268例GDM病例中,7种GDM亚型的构成比如下:T0(7.9%,n=260)、T1(24.2%,n=791)、T2(27.4%,n=897)、T0+1(5.4%,n=175)、T0+2(1.7%,n=56)、T1+2(26.2%,n=855)和T0+1+2(7.2%,n=234)。(2)与FBG水平未升高的GDM亚型(GDM-LR)相比,FBG水平升高的GDM亚型(GDM-HR)表现出更严重的不良预后。(3)多重逻辑回归分析显示,与 GDM-LR 组相比,GDM-HR 组的胎儿出生体重增加(约增加 150 克),剖宫产率更高(调整后的几率比 [aOR]:1.45,95% 置信区间 [CI]:1.19-1.76)、妊娠高血压疾病(aOR:1.78,95% CI:1.35-2.35)、早产(aOR:1.59,95% CI:1.17-2.16)、巨大儿(aOR:2.66,95% CI:2.07-3.43)、LGA 婴儿(aOR:2.46,95% CI:2.05-2.97)和新生儿低血糖(aOR:2.00,95% CI:1.37-2.91)。偏相关分析表明,胎儿出生体重与 FBG 水平呈正相关,r=0.222,P<.001。多重线性回归表明,FBG 每增加 1 毫摩尔/升,胎儿体重估计会增加约 188 克。结论在 GDM 病例中,FBG 升高的 GDM 亚型(GDM-HR)的组成比率相对较低,但与 FBG 不升高的亚型(GDM-LR)相比,其不良结局的风险更高,值得产科医生加强关注。在临床实践中应用这种新的分类方法可以更好地区分 GDM 并对其进行个体化管理。

Trends in sensor-based health metrics during and after pregnancy: descriptive data from the apple women's health study 孕期和产后基于传感器的健康指标趋势:苹果妇女健康研究的描述性数据
Pub Date : 2024-08-14 DOI: 10.1016/j.xagr.2024.100388

Background

While it is known that vital signs and behaviors change during pregnancy, there is limited data on timing and scale of changes for sensor-derived health metrics across pregnancy and postpartum. Wearable technology provides an opportunity to understand physiologic and behavioral changes across pregnancy with greater detail, more frequent measurements, and improved accuracy. The aim of this study is to describe changes in physiologic and behavioral sensor-based health metrics during pregnancy and postpartum in the Apple Women's Health Study (AWHS) and their relationship to demographic factors.

Methods

The Apple Women's Health Study is a digital, longitudinal, observational study that includes U.S. residents with an iPhone and Apple Watch. We evaluated changes from pre-pregnancy through delivery and postpartum for sensor-derived health metrics. Minimum required data samples per day, week and overall were data element specific, and included 12 weeks prior to pregnancy start, and 12 weeks postpartum for pregnancies lasting between 24 and 43 weeks.

Findings

A total of 757 pregnancies from 733 participants were included. Resting heart rate (RHR) increased across pregnancy, peaking in the third trimester (pre-pregnancy median RHR 65.0 beats per minute [BPM], interquartile range [IQR] 60.0–70.2 B.M. third trimester median RHR 75.5 B.M. IQR 69.0–82.0 B.M., with a decrease prior to delivery and nadir postpartum (postpartum median RHR 62.0 B.M. IQR 57.0–66.0 B.M.. Heart rate variability (HRV) decreased from pre-pregnancy (39.9 milliseconds, IQR 32.6–48.3 milliseconds), reaching a nadir in the third trimester (29.9 milliseconds, IQR 25.2–36.4 milliseconds), before rebounding in the last weeks of pregnancy. Measures of activity, such as exercise minutes, stand minutes, step count and Cardio Fitness were all decreased in each trimester compared to pre-pregnancy, with their nadirs postpartum. Total sleep duration increased slightly in early pregnancy (pre-pregnancy 7.2 hours, IQR 6.7–7.7 hours; 1st trimester 7.4 hours, IQR 6.8–7.9 hours), with the lowest sleep duration postpartum (6.2 hours, IQR 5.4–6.8 hours).

Interpretation

Resting heart rate increased during pregnancy, with a decrease prior to delivery, while heart rate variability decreased across pregnancy, with an upward trend before delivery. Behavioral metrics, such as exercise and sleep, showed decreasing trends during and after pregnancy. These data provide a foundation for understanding normal pregnancy physiology and can facilitate hypothesis generation related to physiology, behavior, pregnancy outcomes and disease.

背景虽然人们知道生命体征和行为在怀孕期间会发生变化,但关于传感器得出的健康指标在整个孕期和产后发生变化的时间和规模的数据却很有限。可穿戴技术提供了一个机会,可以更详细、更频繁地测量并提高准确性,从而了解整个孕期的生理和行为变化。本研究旨在描述苹果妇女健康研究(AWHS)中基于传感器的生理和行为健康指标在孕期和产后的变化及其与人口统计学因素的关系。我们评估了从孕前到分娩和产后传感器衍生健康指标的变化。每天、每周和总体所需的最低数据样本量是根据数据元素而定的,包括怀孕开始前 12 周和怀孕 24 至 43 周的产后 12 周。静息心率(RHR)在整个孕期都在增加,在怀孕的第三个三个月达到高峰(孕前中位 RHR 为 65.0 次/分,四分位数间距 [IQR] 为 60.0-70.2 次/分,怀孕的第三个三个月中位 RHR 为 75.5 次/分,IQR 为 69.0-82.0 次/分、分娩前有所下降,产后降至最低点(产后 RHR 中位数为 62.0 B.M.,IQR 为 57.0-66.0 B.M.)。心率变异性(HRV)从怀孕前(39.9 毫秒,IQR 32.6-48.3 毫秒)开始下降,在怀孕的第三个三个月达到最低点(29.9 毫秒,IQR 25.2-36.4 毫秒),然后在怀孕的最后几周回升。与怀孕前相比,每个孕期的活动量(如运动分钟数、站立分钟数、步数和心肺功能)都有所减少,其最低值出现在产后。总睡眠时间在孕早期略有增加(孕前为 7.2 小时,IQR 为 6.7-7.7 小时;孕期前三个月为 7.4 小时,IQR 为 6.8-7.9 小时),产后睡眠时间最短(6.2 小时,IQR 为 5.4-6.8 小时)。运动和睡眠等行为指标在孕期和产后呈下降趋势。这些数据为了解正常妊娠生理提供了基础,并有助于提出与生理、行为、妊娠结局和疾病有关的假设。

Efficacy of Dilapan S compared to foley balloon in preinduction cervical ripening—a noninferiority trial Dilapan S 与 Foley 球囊在宫颈诱导前成熟术中的疗效比较--非劣效性试验
Pub Date : 2024-08-13 DOI: 10.1016/j.xagr.2024.100387

Background

The need for induction of labor is increasing in present obstetric practice. The available non-pharmacological methods for cervical ripening at term are Foley balloon and Dilapan-S. With the gaining popularity of Dilapan-S worldwide, there are very few clinical trials conducted in India to evaluate its effectiveness.

Objective

To compare the efficacy of Dilapan-S and Foley balloons for pre-induction cervical ripening.

Study design

This single-center randomized non-inferiority trial included primi- and multi-gravida women between 37 and 41 weeks of gestation and unfavourable cervix with a Bishop's score between 0 and 2. Using a random number table, patients were assigned to study Group 1 Dilapan-S and to control Group 2 Foley balloon. Dilapan-S or Foley balloon was inserted intracervically and assessed for dilation after 12 hours. Patients with unfavourable dilatation were further provided prostaglandins (PgE 1 and 2) for further augmentation of induction. Primary outcome measures included improvement in Bishop's score, and mode of delivery, followed by time to delivery from intervention, use of other augmentation methods, and maternal and neonatal outcomes.

Results

After screening, 296 patients with Bishop score less than 2, (148 in each group) were enrolled in the study. The number of patients who had vaginal delivery was comparable between both groups (p=.72), and so were the maternal outcomes. Two cases of cord prolapse occurred with Foley balloon. Group 2 showed significant improvement in Bishop's score (p<.001), and Group 1 had a significantly higher use of augmentation with PgE1 (p-.01) and PgE2 (p<.001). The number of contractions was significantly lower in Group 1 (p<.001), and contraction intensity was higher in Group 2. There was no significant difference in cesarean delivery for failed induction of labor between the groups (p=.72). Based on the primary outcome measure, Dilapan-S was found to be non-inferior to the Foley balloon.

Conclusion

Dilapan-S is non-inferior to Foley balloon in achieving pre-induction cervical ripening in term pregnancies, and therefore Dilapan-S can be suggested as an alternative in clinical practice with minimal risks.
背景在目前的产科实践中,引产的需求日益增加。临产时宫颈成熟的非药物方法有 Foley 球囊和 Dilapan-S。研究设计这项单中心随机非劣效性试验纳入了妊娠 37 至 41 周、宫颈不佳且 Bishop 评分在 0 至 2 之间的初产妇和多产妇。通过随机数字表,患者被分配到研究组 1 Dilapan-S 和对照组 2 Foley balloon。在宫颈内插入 Dilapan-S 或 Foley 球囊,12 小时后评估扩张情况。扩张效果不佳的患者将进一步使用前列腺素(PgE 1 和 PgE 2),以进一步增强诱导效果。主要结果指标包括 Bishop 评分的改善情况和分娩方式,其次是干预后的分娩时间、其他扩容方法的使用情况以及产妇和新生儿的预后。结果经过筛选,296 名 Bishop 评分低于 2 分的患者(每组 148 人)被纳入研究。两组患者中经阴道分娩的人数相当(P=0.72),产妇结局也相当。使用 Foley 球囊时发生了两例脐带脱垂。第 2 组的 Bishop 评分有明显改善(p<.001),而第 1 组使用 PgE1(p-.01)和 PgE2(p<.001)扩容的比例明显更高。第一组的宫缩次数明显较少(p<.001),第二组的宫缩强度较高。结论 在足月妊娠引产前宫颈成熟方面,Dilapan-S 的效果优于 Foley 球囊,因此在临床实践中,Dilapan-S 可作为一种风险最小的替代方法。

Pregnant women's knowledge, attitude, and practice toward physical exercise during pregnancy and its associated factors at Dessie town health institutions, Ethiopia 埃塞俄比亚德西镇卫生机构的孕妇对孕期体育锻炼的认识、态度和做法及其相关因素
Pub Date : 2024-08-13 DOI: 10.1016/j.xagr.2024.100391

BACKGROUND

Physical exercise consists of planned, repetitive, and intentional movements that reduce the risk of pregnancy-related complications. Worldwide, there is a high rate of physical inactivity during pregnancy, including in Ethiopia, which has detrimental effects on both pregnant women and their developing fetus.

OBJECTIVE

This study aimed to assess pregnant women's knowledge, attitude, and practice toward physical exercise during pregnancy and its associated factors among antenatal care attendants at health institutions in Dessie, South Wollo Zone, Amhara Region, Ethiopia, in 2023.

STUDY DESIGN

An institutional-based cross-sectional study was conducted among 614 pregnant women receiving antenatal care between January 18, 2023, and February 25, 2023. The study participants were selected using systematic random sampling technique. Data were collected using a pretested, face-to-face interviewer-administered, and semistructured questionnaire. The data were cleaned, coded, and entered into EpiData (version 4.6; www.epidata.dk) and analyzed using SPSS (version 25; SPSS Inc, Chicago, IL). Bivariate and multivariate binary logistic regression analyses were performed to identify factors associated with knowledge, attitude, and practice toward physical exercise during pregnancy. Variables with a P value of <.2 in the bivariate analysis were transferred to the multivariate analysis. Finally, the adjusted odds ratio and 95% confidence interval with a P value of <.05 in the multivariate analysis were considered statistically significant.

RESULTS

The study found that 56.3% of participants had good knowledge, 51.5% of participants had a favorable attitude, and 32.2% of participants practiced physical exercise during pregnancy. Age, educational level, and heard about physical exercise during pregnancy were positively associated with pregnant women's knowledge and attitude. In addition, age, antenatal care follow-up, no history of abortion, ever done physical exercise before becoming pregnant, and good knowledge were positively associated with pregnant women's practice of physical exercise during pregnancy.

CONCLUSION

Our findings indicate that approximately half of the participants had good knowledge and a favorable attitude. However, almost one-third of the participants practiced physical exercise during their pregnancy. It is recommended that antenatal care providers advise pregnant women to strengthen their antenatal care follow-up and offer health education and counseling about the benefits of physical exercise during pregnancy.

背景体育锻炼包括有计划的、重复的和有意识的运动,可降低妊娠相关并发症的风险。在世界范围内,包括埃塞俄比亚在内,孕期缺乏体育锻炼的比例很高,这对孕妇及其发育中的胎儿都有不利影响。本研究旨在评估 2023 年埃塞俄比亚阿姆哈拉地区南沃洛区德西医疗机构的产前护理人员对孕妇孕期体育锻炼及其相关因素的了解、态度和实践。研究对象采用系统随机抽样技术选出。数据收集采用了一份经过预先测试、由访谈者面对面发放的半结构化问卷。数据经过清理、编码后输入 EpiData(4.6 版;www.epidata.dk),并使用 SPSS(25 版;SPSS Inc,芝加哥,伊利诺伊州)进行分析。我们进行了二元和多元二元逻辑回归分析,以确定与孕期体育锻炼的知识、态度和实践相关的因素。双变量分析中 P 值为 <.2 的变量被转入多变量分析。结果研究发现,56.3%的参与者对孕期体育锻炼有良好的认识,51.5%的参与者对孕期体育锻炼持积极态度,32.2%的参与者在孕期进行了体育锻炼。年龄、受教育程度和听说过孕期体育锻炼与孕妇的知识和态度呈正相关。此外,年龄、产前护理随访、无流产史、怀孕前曾做过体育锻炼以及良好的知识与孕妇在孕期进行体育锻炼呈正相关。然而,近三分之一的参与者在孕期进行了体育锻炼。建议产前护理人员建议孕妇加强产前护理随访,并提供有关孕期体育锻炼益处的健康教育和咨询。
