Introduction

There is a research gap on how racism impacts the mental health of midwives in Ontario. Our aim was to conceptualize the impact of racism on racialized midwives in Ontario.

Methods

Informed by constructivist grounded theory, we analyzed data contributed by racialized midwives in Ontario who participated in focus groups and interviews as part of a larger study about mental health. Participants had practiced midwifery within the past 15 months.

Results

Seven participants from 2 focus groups and one individual interview were included. Our conceptualization, Hypervigilance: Being Plugged In, describes cause-and-effect relationships between 3 pairs of external exposures and corresponding internal responses. The 3 paired relationships are: (1) microaggressions and social isolation elicit exhaustion, (2) bias checking and systemic exclusion elicit educator fatigue, and (3) Whiteness, the White gaze, and institutional inaction elicit disenfranchisement. Participants identified 2 recommendations to improve the mental health of racialized midwives: (1) identify and fund racially and ethnically concordant mental health practitioners for mental health support and (2) combat racism within the profession by requiring antiracism training as part of annual membership renewal.

Discussion

Our research has generated a novel conceptualization explaining how exposure to racism negatively impacts the mental health of midwives. This is further supported by the literature with the concept of allostatic overload, whereby allostasis is no longer possible. When this occurs in the body, it can lead to illness and disability. This signifies an alert to the profession and systems partners to address the impact of racism on the workforce. This study provides insight into racialized midwives’ experiences and presents recommendations to counter the impacts of racism.

导言:关于种族主义如何影响安大略省助产士的心理健康的研究差距。我们的目的是概念化种族主义对安大略省种族化助产士的影响。方法:根据建构主义理论,我们分析了安大略省种族化助产士提供的数据,他们参加了焦点小组和访谈,作为一项关于心理健康的大型研究的一部分。参与者在过去15个月内曾从事助产工作。结果:7名参与者来自2个焦点小组和1个个人访谈。我们的概念,高度警惕:被插入,描述了三对外部暴露和相应的内部反应之间的因果关系。这三种配对关系分别是:(1)微侵犯和社会孤立导致疲惫;(2)偏见检查和系统排斥导致教育者疲劳;(3)白人、白人凝视和制度不作为导致剥夺公民权。与会者确定了两项建议,以改善种族化助产士的心理健康:(1)确定并资助种族和民族和谐的心理健康从业者,以提供心理健康支持;(2)通过要求将反种族主义培训作为年度会员更新的一部分,打击职业内的种族主义。讨论:我们的研究产生了一个新的概念,解释了种族主义如何对助产士的心理健康产生负面影响。这一点得到了文献中关于适应负荷概念的进一步支持,即适应不再是可能的。当这种情况发生在体内时,它会导致疾病和残疾。这标志着对专业和系统合作伙伴的警告,以解决种族主义对劳动力的影响。本研究提供了洞察种族化助产士的经验,并提出建议,以对抗种族主义的影响。

The authors thank Ms. DeLuca for engaging with our recent article and emphasizing the role of interprofessional collaborations and training to improve rural midwifery care access.1 We agree and see this as both a policy and research issue. The questions raised are timely, as recent research has shown continued labor and delivery unit closures disproportionately impacting rural US hospitals,2 further limiting rural residents’ access to local perinatal care.

The letter's author highlights numerous factors that may inhibit the growth of rural midwifery, including workforce shortages of other types of perinatal care clinicians, geographic barriers to care, and a lack of infrastructure to incorporate the midwifery model in established practices. Underpinning each of these barriers is the impact that state-level midwifery practice legislation has on the growth of the midwifery care workforce.

The American College of Nurse-Midwives has identified numerous state policies governing certified nurse-midwife and certified midwife (CNM/CM) practice that can expand the midwifery workforce. These include licensure policies for different types of midwives, Medicaid reimbursement parity between midwives and physicians, and whether midwives have the authority to prescribe medications and admit patients to hospitals without physician oversight.3 Researchers have demonstrated such policies’ potential impacts. States with independent practice legislation for CNMs have more practicing midwives per 1,000 births and fewer counties without midwives compared to those that require CNMs to hold practice agreements with supervising physicians.4

Enabling CNMs/CMs to practice independently may have particularly salient effects on the perinatal care workforce in rural areas. Though CNMs/CMs can provide safe, high-quality care within their scopes of practice without physician oversight,5 requiring physician supervision may restrict midwives’ ability to provide care in rural areas,3, 4 even if they desire a rural practice, because clinicians like obstetrician-gynecologists are more concentrated in urban areas.5 In contrast, independent practice legislation may enable CNMs/CMs to practice in communities that otherwise have shortages of perinatal care providers or are longer distances from high-volume or higher acuity clinical settings.

Similar policies that reduce restrictions for certain types of midwives, such as certified professional midwives (CPMs), may be particularly resonant in rural areas. CNMs/CMs are more likely to be concentrated in urban areas,3, 5 while a greater proportion of rural births are attended by CPMs and other types of midwives compared to CNMs/CMs.6 Further, as CPMs and other types of midwives are more likely than CNM

作者感谢DeLuca女士参与了我们最近的文章,并强调了跨专业合作和培训在改善农村助产护理可及性方面的作用我们同意并认为这既是一个政策问题,也是一个研究问题。提出的问题是及时的,因为最近的研究表明,持续的分娩和分娩单位关闭对美国农村医院的影响不成比例,2进一步限制了农村居民获得当地围产期护理的机会。这封信的作者强调了许多可能抑制农村助产发展的因素,包括其他类型围产期护理临床医生的劳动力短缺,护理的地理障碍,以及缺乏将助产模式纳入既定实践的基础设施。支撑这些障碍的是州级助产实践立法对助产护理劳动力增长的影响。美国护士助产士学院已经确定了许多管理认证护士助产士和认证助产士(CNM/CM)实践的州政策,这些政策可以扩大助产士队伍。这些包括不同类型助产士的执照政策,助产士和医生之间的医疗补助补偿,以及助产士是否有权在没有医生监督的情况下开药和让病人住院研究人员已经证明了这些政策的潜在影响。与那些要求cnm与监督医生签订执业协议的州相比,对cnm有独立执业立法的州每1000例分娩中有更多的执业助产士,没有助产士的县更少。使cnm /CMs独立执业可能对农村地区的围产期护理人员产生特别显著的影响。尽管cnm /CMs可以在没有医生监督的情况下在他们的执业范围内提供安全、高质量的护理,但要求医生监督可能会限制助产士在农村地区提供护理的能力,即使他们希望在农村执业,因为像妇产科医生这样的临床医生更集中在城市地区相比之下,独立的执业立法可能使cnm /CMs在缺乏围产期护理提供者或距离大容量或高灵敏度临床机构较远的社区中执业。类似的政策减少了对某些类型的助产士的限制,如注册专业助产士(cpm),可能会在农村地区引起特别的共鸣。cnm /CMs更可能集中在城市地区,而与cnm /CMs相比,农村分娩由cpm和其他类型的助产士接生的比例更高此外,由于cpm和其他类型的助产士比cnm / cm更有可能参加社区分娩(在家分娩,独立分娩中心),因此减少对cpm和其他类型助产士的执业限制可以扩大没有医院分娩服务的农村社区的助产人员队伍,而这些社区需要当地护理。然而,关于生育中心靠近医院的规定限制了cpm在没有医院分娩服务的农村社区扩大以生育中心为基础的助产服务的能力,即使他们可以独立执业。可以肯定的是,患者安全至关重要,因此,在农村或偏远地区执业的所有临床医生,包括助产士和医生,都需要在持续培训、伙伴关系和获得所需转诊的紧急医疗运输方面得到支持。扩大助产实践的政策可以扩大医生和助产士之间的跨专业合作,并支持将助产士纳入围产期护理提供者的新培训模式。医生和助产士之间的跨专业合作在农村医院取得了成功,7农村社区这种合作的增长可以使更多的农村居民获得助产护理模式的选择。除了作者在信中提出的研究问题外,未来的研究可以评估规范助产实践的政策是否对农村和城市地区的助产劳动力产生不同的影响。作者没有需要披露的利益冲突。

致编辑:在“美国农村社区助产护理的可得性”中,Sheffield等人指出,最近关闭产科服务的75%的农村医院不存在助产护理成分这篇文章内容丰富,令人大开眼界。农村分娩人群在获得产科护理方面存在障碍,在选择护理提供者方面更有困难,这一发现突出了一个值得进一步研究的重要领域,可以理解的是,这一领域不在本研究的探讨范围之内。这篇文章激发了人们对美国农村缺乏助产护理的原因的进一步思考。教育、立法和经济障碍阻碍了助产的发展,特别是在农村社区,超过三分之一的农村县缺乏训练有素的围产期服务提供者。2,3由于医疗保健提供者短缺或作为顾问的提供者分布不均,助产士在跨专业合作方面可能面临独特的困难。获得保健的地理距离较远也是农村保健的一个固有障碍。最后,已建立的机构可能缺乏将助产士纳入其系统的基础设施由于这些障碍,以及农村社区围产期资源的严重短缺,有必要进一步研究助产护理的其他潜在障碍,特别是在农村社区。研究人员可以研究的一个因素是,医生和助产士之间目前或过去的跨专业关系是否会影响农村分娩人群获得助产护理的机会。为了使助产发挥最大的潜在影响,助产士必须得到良好的支持,并融入各地的卫生保健系统和团队。对专业间合作的进一步研究可以为满足农村社区需要的创新战略创造机会。这可以从住院医师教育开始,重点是通过在住院医师项目中使用经验丰富的助产士作为教师,将助产士融入医生的早期职业生涯。在我的实习环境中,助产士与住院医师密切合作,教授实践技能并一起进行模拟。阅读这篇文章让我对这种教学策略的潜在长期后果感到好奇。一些研究已经集中在这种跨专业教育模式上,结果显示出更大的合作。最近发表的文章《作为教师的注册护士-助产士:扩大医学生在妇产科见习方面的跨专业合作学习机会》就是一个范例;然而,这方面的研究是有限的。考虑到Sheffield等人文章的发现,包括缺少助产服务的关闭产科部门的数量,所有影响助产护理可用性的因素都值得探索感谢作者。我希望这篇文章以及这些想法将促进进一步的讨论和研究。作者没有个人、专业或财务利益冲突要披露与此提交相关的信息。

Introduction

Black pregnant people are disproportionately impacted by childhood maltreatment and maternal morbidity and mortality related to labor dysfunction. One largely unexplored link between these disparities is the maternal oxytocin system, which is affected by childhood maltreatment and integral to labor. The current study examines relationships between maternal childhood maltreatment, labor duration, and intrapartum synthetic oxytocin requirements.

Methods

This is a secondary data analysis of a completed prospective cohort study involving Black pregnant people recruited from 2 academic medical centers in Atlanta, Georgia. Participants had no health complications, term labor, and a singleton fetus in cephalic presentation (N = 109). Childhood maltreatment was assessed using the Childhood Trauma Questionnaire. Labor duration and synthetic oxytocin data were collected via health record abstraction. Associations were examined between childhood maltreatment, labor duration, and synthetic oxytocin requirements after stratification by mode of labor onset.

Results

No significant associations were found between childhood maltreatment and labor duration in the total sample (N = 109). However, among the induction of labor sample (n = 47), both small-to-moderate and larger associations were found between childhood emotional (β, 0.253; P = .073) and physical (β, 0.398; P = .003) abuse and labor duration after adjusting for parity, epidural analgesia use, and body mass index. Additionally, in the labor induction sample, there were significant, moderate-to-large associations between higher levels of childhood physical abuse with higher intrapartum synthetic oxytocin dose (ρ, 0.433; P = .002), longer duration (ρ, 0.381; P = .008), and higher average dose per hour (ρ, 0.312; P = .033).

Discussion

In a sample of Black pregnant people who underwent labor induction, childhood emotional and physical abuse were associated with longer labor duration. Childhood physical abuse was associated with higher synthetic oxytocin requirements. Further research is needed to understand the potential relationships between maternal childhood maltreatment and labor outcomes to inform future interventions toward birth outcome equity.

背景:黑人孕妇受到儿童虐待和与分娩功能障碍相关的产妇发病率和死亡率的影响不成比例。这些差异之间的一个很大程度上未被探索的联系是母亲的催产素系统,它受到童年虐待的影响,是分娩不可或缺的一部分。目前的研究探讨了母亲童年虐待、分娩持续时间和分娩时合成催产素需求之间的关系。方法:这是一项已完成的前瞻性队列研究的辅助数据分析,该研究涉及从佐治亚州亚特兰大的2个学术医疗中心招募的黑人孕妇。参与者无健康并发症、足月分娩和头位单胎(N = 109)。使用儿童创伤问卷对儿童虐待进行评估。通过健康记录提取收集分娩持续时间和合成催产素数据。根据分娩方式分层后,研究了儿童虐待、分娩持续时间和合成催产素需求之间的关系。结果:在总样本中,儿童虐待与分娩时间无显著关联(N = 109)。然而,在引产样本(n = 47)中,儿童情绪与分娩之间存在小到中等和较大的关联(β, 0.253;P = 0.073)和物理(β, 0.398;在调整胎次、硬膜外镇痛使用和体重指数后,P = 0.003)滥用和分娩持续时间。此外,在引产样本中,较高的儿童身体虐待水平与较高的分娩时合成催产素剂量之间存在显著的中等到较大的关联(ρ, 0.433;P = 0.002),持续时间较长(ρ, 0.381;P = 0.008),且每小时平均剂量较高(ρ, 0.312;P = .033)。讨论:在一个接受引产的黑人孕妇样本中,儿童时期的情感和身体虐待与更长的分娩时间有关。儿童时期的身体虐待与更高的合成催产素需求有关。需要进一步的研究来了解母亲童年虐待和分娩结果之间的潜在关系,以便为未来的分娩结果公平干预提供信息。

Introduction

Birthing people in the United States suffer from poor pregnancy outcomes and a lack of perinatal care providers, especially nurse-midwives. Prenatal and intrapartum care by a certified nurse-midwife (CNM) is associated with improved perinatal health and lower costs among low-risk pregnant people. Medicaid programs in 20 states reimburse CNMs 10% to 25% less than physicians. On January 1, 2006, an Illinois policy went into effect requiring Medicaid to reimburse CNMs at the same rate as physicians. The objective of this study was to evaluate the association between equal Medicaid reimbursement of CNMs and physicians and CNM-led births in Illinois.

Methods

We included all live births to people aged 18 years or older in Illinois between June 1, 2003, and November 30, 2009. We used an interrupted time series analysis, with and without a synthetic control group, to assess the change in the level and trend of the proportion of CNM-attended births after the implementation of the Illinois policy.

Results

The study period included 1,103,238 eligible live births in Illinois. Illinois and the synthetic control group were similar overall. Compared with a synthetic control group, we found an increase of 48.1 per 10,000 live births in the level of the number of births attended by a CNM (95% CI, −175.7 to 272.0) and an increasing trend of births attended by a CNM (2.8 per 10,000 live births; 95% CI, −7.4 to 13.1).

Discussion

These findings support evidence that equitable reimbursement will help increase access to CNMs among the Medicaid population.

简介:在美国分娩的人遭受不良妊娠结局和缺乏围产期护理提供者,特别是护士助产士。在低风险孕妇中,由持证助产士提供产前和产时护理与改善围产期健康和降低费用有关。20个州的医疗补助计划给cnm的补偿比医生少10%到25%。2006年1月1日,伊利诺斯州的一项政策生效,要求医疗补助计划以与医生相同的费率偿还cnm。本研究的目的是评估伊利诺斯州cnm和医生的平等医疗补助报销与cnm主导的分娩之间的关系。方法:我们纳入了2003年6月1日至2009年11月30日期间伊利诺伊州18岁及以上的所有活产婴儿。我们使用中断时间序列分析,有或没有合成对照组,来评估伊利诺斯州政策实施后cnm助产比例的水平和趋势变化。结果:研究期间包括伊利诺伊州1,103,238名符合条件的活产婴儿。伊利诺斯州和合成对照组的总体情况相似。与合成对照组相比,我们发现由CNM接生的婴儿数量水平增加了48.1 / 10,000活产(95% CI, -175.7至272.0),并且由CNM接生的婴儿数量呈增加趋势(2.8 / 10,000活产;95% CI, -7.4 ~ 13.1)。讨论:这些发现支持这样的证据,即公平的报销将有助于在医疗补助人群中增加获得cnm的机会。

Introduction

Breastfeeding has been shown to be associated with improved child cognitive performance, but the causality of this association is still debated because it tends to disappear when accounting for maternal cognitive performance and socioeconomic status. We aimed to explore the relationship between breastfeeding and the cognitive performance of children in the French general population.

Methods

From the PELAGIE woman-child cohort, which included pregnant women between 2002 and 2006 in Brittany (France), 286 children were evaluated using the Wechsler Intelligence Scale for Children (WISC-IV) and the Developmental Neuropsychological Assessment (NEPSY) scales at age 6. Associations between breastfeeding and cognitive performance were assessed using multivariable linear regression models adjusted for maternal verbal cognitive performance and education level, familial stimulation and environment (Home Observation for Measurement of the Environment scale), and Rey's Social Deprivation Index (contextual indicator). In addition, we performed structural equation modeling (SEM) to investigate the complex interrelation between these variables.

Results

Children who were breastfed for at least 4 months had significantly higher scores on the WISC Verbal Comprehension Index (WISC-VCI) than those who were never breastfed or who were breastfed less than 15 days (βadjusted, 4.95 points; 95% CI, 0.54-9.37). Among the 193 children who were breastfed, the duration of breastfeeding, in particular during the first 4 months, was increasingly associated with the WISC-VCI score. We also observed statistically significant associations between breastfeeding itself or the duration of breastfeeding and better performance on several NEPSY subtests, including visual attention, design copying, arrows, and narrative memory. SEM analysis confirmed these associations. No statistical association was observed between breastfeeding and the WISC Working Memory Index or other NEPSY subtests.

Discussion

These data support current national and World Health Organization global 2025 targets of promoting breastfeeding for at least 4 to 6 months.

母乳喂养已被证明与儿童认知能力的提高有关,但这种联系的因果关系仍存在争议,因为当考虑到母亲的认知能力和社会经济地位时,这种联系往往会消失。我们旨在探索母乳喂养与法国普通人群儿童认知表现之间的关系。方法:选取法国布列塔尼地区2002 ~ 2006年孕妇PELAGIE妇幼队列,对286名6岁儿童采用韦氏儿童智力量表(WISC-IV)和发育神经心理评估量表(NEPSY)进行评估。使用多变量线性回归模型评估母乳喂养与认知表现之间的关系,调整了母亲的语言认知表现和教育水平、家庭刺激和环境(家庭环境观察测量量表)以及Rey's社会剥夺指数(情境指标)。此外,我们进行了结构方程模型(SEM)来研究这些变量之间的复杂相互关系。结果:母乳喂养至少4个月的儿童WISC言语理解指数(WISC- vci)得分显著高于从未母乳喂养或母乳喂养少于15天的儿童(β调整后,4.95分;95% ci, 0.54-9.37)。在193名母乳喂养的儿童中,母乳喂养的持续时间,特别是前4个月,与WISC-VCI评分的关系越来越密切。我们还观察到母乳喂养本身或母乳喂养持续时间与几个NEPSY子测试(包括视觉注意力、设计复制、箭头和叙述记忆)的更好表现之间存在统计学上的显著关联。扫描电镜分析证实了这些关联。没有观察到母乳喂养与WISC工作记忆指数或其他NEPSY子测试之间的统计学关联。讨论:这些数据支持目前国家和世界卫生组织2025年全球促进母乳喂养至少4至6个月的目标。

Biodynamic interventions are targeted suggestions for postural changes thought to quicken the progress or ease the discomfort of labor and birth, especially when fetuses are not in the optimal position. Although biodynamic interventions carry almost no risks and come from a rich anecdotal body of evidence, they have generally not been subject to rigorous evaluation. Current clinical practice guidelines support the use of intravenous oxytocin and manual or instrumental rotation for delayed labor progress and fetal malposition; however, these interventions are associated with increased risks of maternal and neonatal morbidities. The use of biodynamic interventions may be an effective alternative to optimizing fetal position and labor progress, with fewer associated risks. This state of the science review examines research describing the efficacy of various biodynamic interventions on labor progress, fetal malposition, and mode of birth within specific clinical contexts. The review also seeks to draw out key findings for clinical practice and identify gaps in the literature for future research.

生物动力学干预是针对体位变化提出的有针对性的建议,被认为可以加快进展或缓解分娩和分娩的不适,特别是当胎儿不在最佳体位时。尽管生物动力干预措施几乎没有风险,而且来自丰富的轶事证据,但它们通常没有受到严格的评估。目前的临床实践指南支持使用静脉催产素和手动或器械旋转延迟产程和胎儿畸形;然而,这些干预措施与孕产妇和新生儿发病率的风险增加有关。使用生物动力干预可能是优化胎儿位置和产程的有效替代方法,相关风险较小。这篇科学综述回顾了在特定临床背景下,描述各种生物动力干预对产程、胎儿畸形和出生方式的功效的研究。该综述还试图为临床实践提出关键发现,并为未来的研究确定文献中的空白。

Artificial Intelligence in Scholarly Publishing 学术出版中的人工智能。

Artificial Intelligence (AI) is all around us. An email titled Meet Gemini, your new AI assistant appeared in my email inbox recently. I was curious about what might be available to help me to become more efficient. I was also a little skeptical and even more cautious. Might this new assistant suggest something inappropriate, irrelevant, or even false?

Questioning the use of AI technologies is particularly relevant in scholarly publishing for authors, editors, peer reviewers, and even everyday readers. We typically ask: were the research methods sound, was the analysis done correctly, are the conclusions appropriate? What is most important to consider related to AI when interacting with the Journal of Midwifery & Women's Health (JMWH) and other scholarly journals?

First, some definitions of AI may be helpful. One expert defined AI as “algorithmic-based technologies that solve complex tasks which previously required human thinking.” Another simply referred to AI as “whatever hasn't been done yet.” In addition, the expert clarified that the intelligence part of AI includes both learning and thinking. A third expert explained AI technologies as requiring higher-level knowledge to do their work.1

New tools referred to as generative AI or GenAI have become available in the last several years. This large language model technology refers to tools that learn from large amounts of publicly available information, including the possibility of copyrighted material, and can generate content such as human-sounding text, images, audio, and video. Numerous ethical concerns have been raised related to their use in scholarly publishing.2 These are important questions to ask and answer, including topics such as intellectual property, other rights to material, privacy, and confidentiality.3 Questions are also being raised about known biases in GenAI based on the material used to train programs and the possibility of amplifying existing biases that may worsen health disparities rather than helping to make improvements. Expert humans guiding the tool development and training will be essential to prevent harm from poorly developed tools.4

The JMWH Editors and Associate Editors approved a new editorial policy related to AI use in 2024.5 The policy interprets guidance provided by thought leaders in scholarly publishing such as the World Association of Medical Editors6 and the JAMA Network, publisher of the AMA Style Guide, adopted by JMWH.7 Authors remain ultimately responsible for all information in their published work, including proper citing of sources, lack of plagiarism, and any material derived from AI tools. Any use of such tools must be acknowledged, including which tool(s) were used and how they were used. In addition, GenAI

人工智能(AI)就在我们身边。最近,我的邮箱里出现了一封题为《遇见双子座,你的新人工智能助手》的邮件。我很好奇有什么可以帮助我变得更有效率。我也有点怀疑,甚至更加谨慎。这个新助理会不会提出一些不合适、不相关甚至是错误的建议?对于作者、编辑、同行评审甚至日常读者来说,质疑人工智能技术的使用与学术出版尤其相关。我们通常会问:研究方法是否合理,分析是否正确,结论是否恰当?在与《助产学杂志》互动时,最重要的是要考虑与人工智能相关的什么?妇女健康(JMWH)和其他学术期刊?首先,人工智能的一些定义可能会有所帮助。一位专家将人工智能定义为“基于算法的技术,可以解决以前需要人类思考的复杂任务。”还有人将人工智能简单地称为“尚未完成的事情”。此外,专家澄清说,人工智能的智能部分包括学习和思考。第三位专家解释说,人工智能技术需要更高层次的知识才能完成工作。在过去的几年里,被称为生成人工智能或GenAI的新工具已经出现。这种大型语言模型技术指的是从大量公开可用信息中学习的工具,包括可能有版权的材料,并且可以生成像人类声音的文本、图像、音频和视频等内容。在学术出版中使用它们引起了许多伦理问题这些都是需要问和回答的重要问题,包括知识产权、材料的其他权利、隐私和保密等主题人们还对GenAI中基于培训项目所用材料的已知偏见提出了质疑,并提出了放大现有偏见的可能性,这些偏见可能会加剧健康差距,而不是有助于改善健康状况。指导工具开发和培训的专家对于防止开发不良的工具造成伤害至关重要。4. JMWH编辑和副编辑批准了一项新的与人工智能使用相关的编辑政策,该政策解释了学术出版领域的思想领袖提供的指导,如世界医学编辑协会6和JAMA网络(AMA风格指南的出版商),JMWH采用了该政策。7作者对其发表的作品中的所有信息负有最终责任,包括正确引用来源,无抄袭,以及任何来自人工智能工具的材料。任何此类工具的使用都必须得到确认,包括使用了哪些工具以及如何使用。此外,GenAI工具可能不被认为是作者,因为它们不是人类,因此不能对工作负责。编辑也有责任承认使用了任何人工智能工具。这些工具的使用可能包括生成提供给作者和审稿人的内容。编辑负责使用旨在检测在提交审稿的稿件中使用GenAI内容的工具目前,JMWH将所有稿件提交给相似度识别工具,以努力检测可能的抄袭。作者和同行审稿人将被要求确认其工作中是否使用了人工智能工具,并声明在JMWH政策的下一次更新中准确、透明地描述了这些工具。同行评审是人工智能工具可能用于评估手稿和撰写评论的另一个领域。使用人工智能从提交的手稿中生成同行评议的做法目前是不允许的,因为它需要上传作者的文件供工具使用。该内容保留在工具中。稿件提交给期刊审查,可能出版是作者的财产。因此,在文章正式发表之前,这些信息不能以任何方式共享或使用,如果这是手稿的处置。5,6一般读者越来越意识到社交媒体和其他场所产生的虚假信息,可能会更加意识到学术文献中可能存在的不准确或虚假信息。读者可以适当地期望编辑和出版商对诸如编写文本、生成图像和制作视频材料等工具的滥用保持警惕。人工智能工具的使用存在伦理问题;这些工具必须在人为监督和适当限制下负责任地使用。然而,人工智能在研究和出版方面也有帮助。一些用途包括自动化重复和耗时的任务,例如生成和限制文献搜索,以获得特定研究领域最重要的资源。自动化使用大型数据集的初始步骤是另一个例子。 与作者身份和同行评审相关,人工智能工具可以帮助编辑团队和出版商提高高效运营,从而改善同行评审流程,为作者和审稿人提供更好、更及时的服务。人工智能工具可以在手稿起草后协助修改和同行评审,并促进对研究要点的总结,促进文章发表后的进一步传播。人工智能的未来用途可能包括识别研究中的差距和促进科学家之间的合作。JMWH的读者可以相信,我们的编辑团队和出版商3,5正在与当前在学术出版中使用人工智能和其他技术的最佳思路保持一致。我们欢迎来自作者、审稿人和读者的意见。随着新工具的出现,JMWH将继续观察和学习,以支持我们的出版活动,并为作者和其他人提供与人工智能工具的道德使用相关的指导。为期刊编辑和出版商提供道德指导的组织可以在出版过程中为作者、审稿人和其他人提供建议。在使用人工智能工具时,人类的监督和责任至关重要。保持健康的怀疑态度,应用当前最好的道德原则和指导,并寻找自信地改进和创新学术出版的方法,将指导我们前进的道路。也许是时候认识双子座了。

Introduction

Perinatal depression affects approximately 20% of childbearing individuals and is associated with adverse perinatal outcomes. Nonpharmacological therapies are effective for mild to moderate depression, but multiple access barriers exist, including financial constraints and the inconvenience of in-person appointments. Remote access (ie, telehealth) to services is a promising option, but few studies have evaluated the effectiveness of this approach. The objective of this study was to use a mixed methods approach in a randomized controlled trial to evaluate the effectiveness of a group videoconference intervention to reduce symptoms of perinatal depression.

Methods

Participants were assigned to a videoconference intervention group (VCI; mindfulness-based cognitive behavioral therapy) or an attention control group (AC; childbirth preparation or early parenting education) via a videoconference system. Groups of 4 to 6 pregnant and postpartum individuals with mild to moderate symptoms of depression attended a one-hour session for 9 weeks using an electronic device from their own home. The Edinburgh Postnatal Depression Scale (EPDS) measured depression symptoms before and after intervention with follow-up to 8 months. Focus groups assessed participants’ telehealth experiences and were analyzed for common themes.

Results

From May 2020 through May 2022, 81 participants were randomized, and 69 (85.2%) ultimately initiated study participation (36 in VCI, 33 in AC group). Participants in both groups had a significant decrease in EPDS score of 3.36 (95% CI, 4.55-2.17) that was maintained 8 months postintervention. There were no significant interactions between time and intervention group (all P >.249). In the focus group analysis, themes of connection, shared experience, empowerment, and community building were consistent between the 2 intervention groups.

Discussion

Both intervention groups had clinically meaningful improvement in EPDS scores up to 8 months postintervention. Anchored in the common themes in the qualitative analysis, our results suggest that participation in telehealth group sessions, regardless of session content, may be beneficial in reducing depression symptom burden.

导读:围产期抑郁症影响约20%的育龄个体,并与不良围产期结局相关。非药物治疗对轻度至中度抑郁症有效,但存在多重障碍,包括财政限制和亲自预约的不便。远程获取(即远程保健)服务是一个很有前途的选择,但很少有研究对这种方法的有效性进行评估。本研究的目的是在一项随机对照试验中使用混合方法来评估小组视频会议干预减轻围产期抑郁症症状的有效性。方法:参与者被分配到视频会议干预组(VCI;基于正念的认知行为疗法)或一个注意力控制组(AC;分娩准备或早期育儿教育)通过视频会议系统。每组4至6名有轻度至中度抑郁症状的孕妇和产后个体在家中使用电子设备进行为期9周的1小时训练。爱丁堡产后抑郁量表(EPDS)测量干预前后的抑郁症状,随访8个月。焦点小组评估了参与者的远程保健经验,并对共同主题进行了分析。结果:从2020年5月到2022年5月,81名参与者被随机分组,69名(85.2%)最终开始参与研究(VCI组36名,AC组33名)。干预后8个月,两组受试者的EPDS评分均显著下降3.36 (95% CI, 4.55-2.17)。时间与干预组间无显著交互作用(P均为0.249)。在焦点小组分析中,两个干预组的连接、分享经验、赋权和社区建设主题是一致的。讨论:两个干预组在干预后8个月EPDS评分均有临床意义的改善。根据定性分析的共同主题,我们的研究结果表明,参与远程医疗小组会议,无论会议内容如何,都可能有助于减轻抑郁症状负担。

产后出血(PPH)被定义为出生后24小时内失血500毫升或更多在美国,PPH的发生率约为1%至3%。2在全球范围内,20%的妊娠相关死亡归因于PPH,1在美国,约11%的妊娠相关死亡是由PPH引起的。3可能影响PPH发病率的一个因素是第三产程的长度和过程,即从新生儿出生到胎盘和膜完全排出的时期一般认为第三阶段的预期长度为30分钟在第三阶段延长的情况下,建议的管理通常是人工移除胎盘。6,7最近,一些临床医生和研究人员开始考虑减少第三产程的待产管理时间,并建议在20分钟后人工取出胎盘。de Vries10及其同事进行了一项系统回顾和荟萃分析,以评估阴道分娩后第三产程长度与产妇不良结局之间的关系。他们还试图确定是否可以通过比目前的临床实践更早地进行人工摘除胎盘来降低不良产妇结局的风险。作者对7个数据库进行了搜索,并筛选了高收入国家关于预防PPH的国家指南的参考列表。在2000年1月1日至2023年6月13日期间以英语、法语、德语、意大利语和荷兰语发表的随机试验、比较研究、前瞻性和回顾性队列试验均符合纳入本综述的条件。主要关注的结局是产妇不良结局,定义为分娩时或分娩后发生的任何并发症,如PPH、输血、重症监护病房入院和围产期子宫切除术。次要结局是不良结局的风险,因为它与第三产程的长度有关。研究人员确定了16篇文章讨论了第三产程长度与产妇结局之间的关系,3篇文章评估了人工摘除胎盘的时间与产妇不良结局之间的关系。一篇文章测量了两种结果,所以总共有18篇文章被纳入完整的综述。纳入的研究在美国、澳大利亚、丹麦、荷兰、以色列、瑞士、瑞典、日本和埃及进行,其中一项研究在多个国家进行;作者没有说明这18项研究中有多少是在每个国家进行的。1项研究的偏倚风险为低,7项为中等,10项为高。提出PPH可能性比值比(OR)的研究被纳入meta分析,无论偏倚等级如何。为了研究第三产程长度与混合风险分娩人群中PPH可能性之间的关系,当第三产程在15分钟后测量时,荟萃分析纳入了4项研究,共评估了39,324个事件或分娩。PPH的可能性是前者的5.55倍(OR, 5.55;95% CI, 1.74-17.72),第三阶段分娩持续15分钟或更长时间的人比第三阶段分娩时间少于15分钟的人。另一项荟萃分析考虑了在30分钟后测量第三产程时出血的混合风险人群(5项研究,N = 21966个事件),发现第三产程为30分钟或更长时间的人发生PPH的几率明显高于第三产程小于30分钟的人(or, 3.12;95% ci, 1.83- 5.30)。作者纳入了各种额外的分析,由于纳入的研究数量或结果测量的异质性,其中一些不符合元分析的预期。作者还指出,PPH的定义在纳入的研究中有所不同,有些使用1000 mL的定义,有些使用500 mL的定义。当PPH是分析的主要结果时,这是一个显著的差异。他们无法就人工摘除胎盘的时机和不良后果的风险得出结论。这篇系统综述和荟萃分析的作者利用他们的分析结果提出,第三产程应该被重新定义为持续时间少于15分钟,尽管他们注意到,这里确定的第三产程长度与PPH之间的关联并不意味着因果关系。此外,他们没有发现证据表明人工摘除胎盘是缩短分娩第三阶段的主要干预措施,是减少不良产妇结局的有效干预措施。 虽然当分娩的人经历较长的第三阶段分娩时,他们更有可能经历出血,这可能是由于一旦诊断出延长的第三阶段后进行的后续干预。这里的研究结果并不表明临床实践发生了变化,尽管在美国产科实践的主要期刊之一上发表的引人注目的标题确实有可能影响实践。在进一步的证据表明可以安全缩短第三产程和降低PPH风险的干预措施之前,临床医生最好遵循目前的第三产程管理实践指南。
