Background

The Advisory Committee on Immunization Practices (ACIP) and the American College of Obstetricians and Gynecologists (ACOG) recommend that all pregnant persons receive any licensed, recommended, and age-appropriate inactivated influenza vaccine (SD-IIV) or recombinant influenza vaccine (RIV) to protect against influenza and influenza-related complications. RIV was safe and efficacious in pre- and postlicensure studies, however there is limited RIV safety data in pregnant persons.

Objective

To evaluate the safety of quadrivalent recombinant influenza vaccine (RIV4) versus a quadrivalent standard-dose, inactivated influenza (SD-IIV4) in a large cohort of pregnant persons and their infants.

Study Design

This postlicensure observational safety study conducted at Kaiser Permanente Northern California evaluated the subset of pregnant persons vaccinated in routine care as part of a larger cluster-randomized vaccine effectiveness study comparing RIV4 vs. SD-IIV4 (ClinicalTrials.gov NCT03694392). We identified pregnancy (spontaneous abortion, preterm labor, stillbirth/fetal death, congenital/fetal anomalies detected during pregnancy, eclampsia/pre-eclampsia, placental abruption), birth (preterm birth, low birth weight, small for gestational age), and neonatal/infant outcomes (infant death, failure to thrive, congenital anomalies detected after delivery) using diagnostic codes among pregnant persons ≥18 years immunized with RIV4 or SD-IIV4 during the 2018/19 and 2019/20 influenza seasons and their infants. We used conditional logistic regression adjusted for age group, race, ethnicity, trimester of influenza vaccination, comorbidities, and BMI, stratified by gestational age to estimate the odds ratio (OR) of pregnancy outcomes following vaccination with RIV4 vs. SD-IIV4. Using logistic regression, we separately estimated the adjusted OR of birth and neonatal/infant outcomes in the first year of life (eg, death) in infants of RIV4 vs. SD-IIV4 vaccinated pregnant persons.

Results

The study population included 48,781 pregnant persons (RIV4 = 14,981; SD-IIV4 = 33,800) and 47,394 live births (RIV4 = 14,538; SD-IIV4 = 32,856). There was no statistical difference in any pregnancy outcome or in birth and neonatal/infant outcome between RIV4 vs. SD-IIV4 vaccinated pregnant persons and their infants.

Conclusion

Compared with receipt of a SD-IIV4 during pregnancy, this large study did not identify any pregnancy, birth, or neonatal/infant safety concerns following receipt of a RIV4 during pregnancy and demonstrates that the safety of RIV4 in pregnancy was similar to SD-IIV4. This study provides additional evidence regarding the safety of influenza vaccination in pregnant persons and further supports ACIP and ACOG recommendations that all pregnant persons receive an inactivated or recombinant influenza vaccine.
背景免疫接种实践咨询委员会(ACIP)和美国妇产科医师学会(ACOG)建议所有孕妇接种任何许可、推荐和适龄的灭活流感疫苗(SD-IIV)或重组流感疫苗(RIV),以预防流感和流感相关并发症。在许可前和许可后的研究中,RIV是安全有效的,但RIV在孕妇中的安全性数据却很有限。研究目的在一大批孕妇及其婴儿中评估四价重组流感疫苗(RIV4)与四价标准剂量灭活流感疫苗(SD-IIV4)的安全性。研究设计这项在北加州凯撒医疗机构进行的许可后安全性观察研究评估了在常规护理中接种疫苗的孕妇子集,该子集是比较 RIV4 与 SD-IIV4 的大型群组随机疫苗有效性研究(ClinicalTrials.gov NCT03694392)的一部分。我们确定了妊娠(自然流产、早产、死胎/胎儿死亡、妊娠期间发现的先天性/胎儿畸形、子痫/子痫前期、胎盘早剥)、分娩(早产、低出生体重、胎龄小)和新生儿/婴儿结局、以及新生儿/婴儿结局(婴儿死亡、发育不良、产后发现先天性畸形),使用诊断代码对在 2018/19 和 2019/20 流感季节接受 RIV4 或 SD-IIV4 免疫接种的≥18 岁孕妇及其婴儿进行分析。我们使用条件逻辑回归法对年龄组、种族、民族、接种流感疫苗的三个月、合并症和体重指数进行了调整,并按孕龄进行分层,以估计接种 RIV4 与 SD-IIV4 疫苗后妊娠结局的几率比 (OR)。使用逻辑回归法,我们分别估算了接种 RIV4 与 SD-IIV4 疫苗的孕妇的婴儿出生和新生儿/婴儿出生后第一年的结果(如死亡)的调整 OR。结论与妊娠期接种 SD-IIV4 相比,这项大型研究没有发现妊娠期接种 RIV4 后出现任何妊娠、分娩或新生儿/婴儿安全问题,并表明妊娠期接种 RIV4 的安全性与 SD-IIV4 相似。这项研究为孕妇接种流感疫苗的安全性提供了更多证据,并进一步支持了 ACIP 和 ACOG 关于所有孕妇接种灭活或重组流感疫苗的建议。

Background

Effective patient counseling in Obstetrics and gynecology is vital. Existing language barriers between Spanish-speaking patients and English-speaking providers may negatively impact patient understanding and adherence to medical recommendations, as language discordance between provider and patient has been associated with medication noncompliance, adverse drug events, and underuse of preventative care. Artificial intelligence large language models may be a helpful adjunct to patient care by generating counseling templates in Spanish.

Objectives

The primary objective was to determine if large language models can generate proficient counseling templates in Spanish on obstetric and gynecology topics. Secondary objectives were to (1) compare the content, quality, and comprehensiveness of generated templates between different large language models, (2) compare the proficiency ratings among the large language model generated templates, and (3) assess which generated templates had potential for integration into clinical practice.

Study design

Cross-sectional study using free open-access large language models to generate counseling templates in Spanish on select obstetrics and gynecology topics. Native Spanish-speaking practicing obstetricians and gynecologists, who were blinded to the source large language model for each template, reviewed and subjectively scored each template on its content, quality, and comprehensiveness and considered it for integration into clinical practice. Proficiency ratings were calculated as a composite score of content, quality, and comprehensiveness. A score of >4 was considered proficient. Basic inferential statistics were performed.

Results

All artificial intelligence large language models generated proficient obstetrics and gynecology counseling templates in Spanish, with Google Bard generating the most proficient template (p<0.0001) and outperforming the others in comprehensiveness (P=.03), quality (P=.04), and content (P=.01). Microsoft Bing received the lowest scores in these domains. Physicians were likely to be willing to incorporate the templates into clinical practice, with no significant discrepancy in the likelihood of integration based on the source large language model (P=.45).

Conclusions

Large language models have potential to generate proficient obstetrics and gynecology counseling templates in Spanish, which physicians would integrate into their clinical practice. Google Bard scored the highest across all attributes. There is an opportunity to use large language models to try to mitigate the language barriers in health care. Future studies should assess patient satisfaction, understanding, and adherence to clinical plans following receipt of these counseling templates.
背景妇产科中有效的患者咨询至关重要。讲西班牙语的患者和讲英语的医疗服务提供者之间现有的语言障碍可能会对患者理解和遵守医疗建议产生负面影响,因为医疗服务提供者和患者之间的语言不一致与不遵守用药规定、不良药物事件和预防性护理使用不足有关。人工智能大语言模型可以生成西班牙语咨询模板,从而成为患者护理的有益辅助工具。目标主要目标是确定大语言模型是否能生成熟练的西班牙语妇产科主题咨询模板。次要目标是:(1) 比较不同大型语言模型生成模板的内容、质量和全面性;(2) 比较大型语言模型生成模板的熟练程度评级;(3) 评估哪些生成模板具有融入临床实践的潜力。研究设计横断面研究使用免费开放的大型语言模型生成有关选定妇产科主题的西班牙语咨询模板。母语为西班牙语的执业妇产科医生在对每个模板的源大语言模型进行盲法处理后,对每个模板的内容、质量和全面性进行审查和主观评分,并考虑将其纳入临床实践。熟练度评级是根据内容、质量和全面性的综合得分计算得出的。4分为熟练。结果所有人工智能大型语言模型都生成了熟练的西班牙语妇产科咨询模板,其中谷歌巴德生成的模板最为熟练(P<0.0001),在全面性(P=.03)、质量(P=.04)和内容(P=.01)方面均优于其他模板。微软必应在这些方面得分最低。结论大语言模型有可能生成熟练的西班牙语妇产科咨询模板,医生会将其融入临床实践中。在所有属性中,谷歌巴德得分最高。我们有机会使用大型语言模型来缓解医疗保健中的语言障碍。未来的研究应评估患者在收到这些咨询模板后的满意度、理解力和对临床计划的依从性。

Background

Time-lapse technology (TLT) has emerged as a significant advancement in the field of assisted reproductive technology (ART), providing continuous observation of embryos. However, limited information exists on the adoption of TLT across ART facilities and the clinical implications of its application in embryo evaluation and fertilization verification. The existing literature has not yet comprehensively examined how TLT data are utilized to optimize ART outcomes, particularly in Japan, where ART practices are highly prevalent.

Objectives

This study aimed to investigate the adoption rate of TLT and its clinical effects on fertilization verification, embryo evaluation, and utilization of ART in Japan.

Study Design

An online survey was conducted from December 23, 2022, to January 16, 2023, in 616 ART facilities with both email and mailed notices. The survey investigated the utilization of TLT in each facility's evaluation of oocyte morphology, fertilization, embryo culture, and morphology.

Results

Overall, 345 responses were analyzed. Of these, only 42.6% confirmed fertilization at 16 to 18 hours after insemination. Most facilities defined normally fertilized eggs as 2 pronuclei (2PN; 53.3%) or a combination of a second polar body extrusion and 2PN (44.9%). Overall, 54.6% of the facilities had adopted TLT, and 76.9% to 96.9% of these facilities used TLT images for fertilization verification. At these centers, the use of 0PN embryos decreased, whereas the use of 2.1PN embryos increased. The rates of culture medium supplemented with antioxidants and hyaluronan were significantly higher in facilities with TLT than in those without TLT. TLT images were used for embryo evaluation in 94.3% of the facilities, while 31.0% used a combination of TLT images and artificial intelligence-based scoring systems.

Conclusions

While TLT use is widespread in Japan, its application in evaluating fertilization and embryo development stages varies across facilities. Reaching a consensus on the optimal use of the TLT system will enhance the effectiveness, safety, and efficiency of ARTs.
背景延时技术(TLT)是辅助生殖技术(ART)领域的一项重大进步,可对胚胎进行连续观察。然而,关于各辅助生殖技术机构采用 TLT 的情况及其应用于胚胎评估和受精验证的临床意义的信息十分有限。本研究旨在调查 TLT 在日本的采用率及其对受精验证、胚胎评估和 ART 利用的临床影响。研究设计于 2022 年 12 月 23 日至 2023 年 1 月 16 日对 616 家 ART 机构进行了在线调查,并通过电子邮件和邮寄方式发出通知。调查调查了各机构在评估卵母细胞形态学、受精、胚胎培养和形态学时对 TLT 的使用情况。其中,只有 42.6% 在人工授精后 16 至 18 小时确认受精。大多数机构将正常受精卵定义为 2 个原核(2PN;53.3%)或第二极体挤出和 2PN 的组合(44.9%)。总体而言,54.6%的机构采用了TLT,其中76.9%至96.9%的机构使用TLT图像进行受精验证。在这些中心,0PN 胚胎的使用率有所下降,而 2.1PN 胚胎的使用率有所上升。使用 TLT 的机构使用添加抗氧化剂和透明质酸的培养基的比例明显高于未使用 TLT 的机构。94.3% 的机构使用 TLT 图像进行胚胎评估,31.0% 的机构结合使用 TLT 图像和基于人工智能的评分系统。就 TLT 系统的最佳使用达成共识将提高 ART 的有效性、安全性和效率。

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。

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。

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 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。

Background

The Coronavirus disease 2019 (COVID-19) pandemic led to healthcare system changes aimed at minimizing disease transmission that impacted experiences with obstetric healthcare.

Objective

To explore experiences of clinicians providing obstetric care during the COVID-19 pandemic.

Study Design

Qualitative, in-depth, semi-structured interviews were conducted with five nurse practitioners and 16 obstetrical physicians providing a mix of outpatient and inpatient obstetric care during the COVID-19 pandemic in a mid-sized, Midwestern city in the United States. Interviews elucidated challenges and facilitators of obstetric care provision and vaccination of pregnant patients against COVID-19 during the pandemic. Transcripts were coded inductively then deductively using the Health Equity Implementation Framework (HEIF), which integrates a disparities framework and implementation framework to highlight multilevel factors that influence obstetric care. Thematic analysis was conducted, and thematic saturation was reached.

Results

We interviewed 21 clinicians. Clinicians recounted personal challenges such as social isolation and burnout that could be countered by social support. Challenges within the clinical encounter included implementation of infection mitigation efforts, vaccine counseling, and limitations of telehealth. However, when successfully implemented, telehealth facilitated care and circumvented barriers. Clinicians cited challenges at the healthcare system level such as rapidly evolving knowledge and recommendations, restrictive visitor policies, personnel shortage, and inadequate institutional resources to support pandemic-related stressors. However, interdisciplinary care and guidelines available for clinicians facilitated care. Clinicians reported that challenges at the societal level included financial strain, lack of childcare, medical mistrust, politicization of medicine, misinformation, and racism. Societal-level facilitators included insurance access, community outreach, positive policy changes, and fostering trust in medicine.

Conclusion

The pandemic produced unique stressors and exacerbated existing challenges for clinicians providing obstetric care. Applying the HEIF to the findings emphasizes the influence of societal factors on all other levels. Identified facilitators can inform interventions to address stressors in obstetric care that have resulted from the changed sociopolitical landscape of the pandemic.
背景2019年冠状病毒病(COVID-19)大流行导致医疗保健系统发生变化,旨在最大限度地减少疾病传播,从而影响了产科医疗保健的经验。研究设计在美国中西部一个中等规模的城市,对COVID-19大流行期间提供门诊和住院产科混合护理的5名执业护士和16名产科医生进行了定性、深入、半结构化访谈。访谈阐明了大流行期间提供产科护理和为孕妇接种 COVID-19 疫苗所面临的挑战和促进因素。采用健康公平实施框架(Health Equity Implementation Framework,HEIF)对访谈记录进行归纳编码,然后进行演绎编码,该框架整合了差异框架和实施框架,以强调影响产科护理的多层次因素。我们对 21 名临床医生进行了访谈。临床医生讲述了个人面临的挑战,如社会隔离和职业倦怠,这些挑战可以通过社会支持来解决。临床工作中遇到的挑战包括感染缓解工作的实施、疫苗咨询以及远程医疗的局限性。然而,当远程医疗成功实施时,它能促进护理工作并绕过障碍。临床医生提到了医疗保健系统层面的挑战,如快速发展的知识和建议、限制访客的政策、人员短缺以及支持与大流行相关的压力的机构资源不足。然而,为临床医生提供的跨学科护理和指南促进了护理工作。临床医生报告说,社会层面的挑战包括经济压力、缺乏儿童保育、医学不信任、医学政治化、错误信息和种族主义。社会层面的促进因素包括保险获取、社区外联、积极的政策变化以及促进对医学的信任。将 HEIF 应用于研究结果强调了社会因素对所有其他层面的影响。已确定的促进因素可为干预措施提供参考,以解决因大流行病导致的社会政治环境变化而产生的产科护理压力。

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。
