Abstract
BACKGROUND Breech presentation is observed in 3-4% at term of pregnancy and is one of the leading causes of cesarean section. There is no established treatment for breech presentation before 36 weeks. A retrospective cohort study was conducted to demonstrate that the lateral position is effective for breech presentation. However, there are no randomized controlled trials evaluating lateral position management for breech presentation. Here, we described the methodology of a randomized controlled trial of a cephalic version for breech presentation in the third trimester by lateral postural management (BRLT study). METHODS The BRLT study is an open-label, randomized controlled trial with two parallel groups allocated in a 1:1 ratio to examine the lateral position management for breech presentation, as compared with expectant management care. An academic hospital in Japan will enroll 200 patients diagnosed with a breech presentation by ultrasonography between 28 + 0 weeks and 30 + 0 weeks. Participants in the intervention group will be instructed to lie on their right sides for 15 min three times per day if the fetal back was on the left side or lie on their left sides if the fetal back was on the right side. The instruction will be given every 2 weeks after confirmation of fetal position, and the lateral position will be instructed until the cephalic version, and after the cephalic version, the reverse lateral position will be instructed until delivery. The primary outcome is cephalic presentation at term. The secondary outcomes are cesarean delivery, cephalic presentation 2, 4, and 6 weeks after the instruction, and at delivery, recurrent breech presentation after cephalic version, and adverse effects. DISCUSSION This trial will answer whether the lateral positioning technique is effective in treating breech presentation and, depending on the results, may provide a very simple, less painful, and safe option for treating breech presentation before 36 weeks, and it may impact breech presentation treatment.

Cephalic version by postural management in the lateral position without the knee-chest position for primiparous breech presentation: A retrospective cohort study. J Obstet Gynaecol Res 2022; 48:703-708. [PMID: 34994031 DOI: 10.1111/jog.15149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Revised: 12/15/2021] [Accepted: 12/29/2021] [Indexed: 11/30/2022]
Abstract
AIM This study aimed to determine the efficacy of postural management in the lateral position for primiparous breech presentation. METHODS A retrospective cohort study was conducted at a single institution from January 2020 through December 2020. Participants were singleton primiparous pregnant women diagnosed with breech presentation between 28 + 0 and 29 + 6 weeks of gestation. The exclusion criteria were scheduled cesarean delivery, uterine malformation, transverse position, and scheduled delivery at another hospital. A doctor instructed the women in the intervention group to lie on their right sides several times a day if the fetal back was on the left side or lie on their left sides if the fetal back was on the right side. The knee-chest position and other methods were not recommended. The control group received expectant management care. The primary endpoint was the percentage of fetuses in a cephalic presentation 2 weeks later. RESULTS Of the 56 women included in the study, 17 women were instructed to lie in the lateral position, and 39 women received expectant management care only. After 2 weeks, women who were instructed to lie in lateral position had a higher rate of fetal cephalic version than the control group (82.4% [14/17] vs. 43.6% [17/39], p = 0.017). No study participants experienced adverse effects. CONCLUSIONS Two weeks of postural management in the lateral position without the knee-chest position significantly reduced the rate of primiparous breech presentation in the third trimester of pregnancy.

Abstract
OBJECTIVE To evaluate the moxibustion for turning fetuses from breech to vertex presentation. MATERIALS AND METHODS This was a single-center prospective study. All pregnant women carrying a fetus in breech presentation between the 32 and 35 gestational weeks were offered moxibustion application. The primary outcomes were vertex presentation at 37 weeks of gestation, vertex presentation at birth, and vaginal birth rates. A secondary analysis was performed to understand the effect of parity, type of breech presentation, body mass index (BMI), placental location, gender, and fetal birth weight on the presentation at birth. RESULTS There were 63 cases in the study group and 245 cases in the control group. The rate of vertex presentation at term was found to be higher in the moxibustion group compared to controls (66.7 vs. 48.2%, p=0.022). There were 45 (71.4%) and 131 (53.5%) fetuses with vertex presentation at birth in the study and control groups, respectively (p=0.020). Overall, vaginal delivery rate was higher in the study group (50.8 vs. 37.1%, p=0.048). Multiparity and higher birth weight were associated with increased rates of vertex presentation in the moxibustion and control groups. CONCLUSION Moxibustion application increased the rate of vertex presentation at birth and also vaginal delivery rate compared with expectant management. Offering moxibustion between the 32nd and 36th week of gestation may provide women with a singleton fetus in breech presentation an opportunity for a vaginal birth.

Abstract
OBJECTIVE To compare the effectiveness of additional moxibustion at point BL67 with moxibustion at a non-specific acupuncture point and with usual care alone to correct non-vertex presentation. METHODS This was a multicentre randomised controlled trial in which 406 low-risk pregnant women with a fetus in ultrasound breech presentation, with a gestational age of 33-35 weeks, were assigned to (1) true moxibustion at point BL67 plus usual care; (2) moxibustion at SP1, a non-specific acupuncture point (sham moxibustion) plus usual care; or (3) usual care alone. The primary outcome was cephalic presentation at birth. Women were recruited at health centres in primary healthcare. RESULTS In the true moxibustion group, 58.1% of the full-term presentations were cephalic compared with 43.4% in the sham moxibustion group (RR 1.34, 95% CI 1.05 to 1.70) and 44.8% of those in the usual care group (RR 1.29, 95% CI 1.02 to 1.64). The reduction in RR of the primary outcome in women allocated to the true moxibustion group compared with the usual care group was 29.7% (95% CI 3.1% to 55.2%) and the number needed to treat was 8 (95% CI 4 to 72). There were no severe adverse effects during the treatment. CONCLUSIONS Moxibustion at acupuncture point BL67 is effective and safe to correct non-vertex presentation when used between 33 and 35 weeks of gestation. We believe that moxibustion represents a treatment option that should be considered to achieve version of the non-vertex fetus. TRIAL REGISTRATION Current Controlled Trials ISRCTN10634508.

Abstract
Health care practitioners and researchers commonly call for greater reliance on evidence as a means to achieve improvement in quality of care. Systematic reviews provide a means to accelerate the use of evidence-based clinical interventions and public health practices. The extent to which these time- and resource-intensive systematic reviews currently address critical maternal health priorities in the intrapartum period is unclear. This analysis summarises key maternal health and research priorities, maps these priorities to existing reviews, identifies gaps in the literature that can be addressed with systematic reviews, and highlights key methodological concerns in conducting systematic reviews. The analysis draws on published data on maternal morbidities and an overview of 108 systematic reviews in Medline in the past 5 years using the MeSH terms 'Delivery, Obstetric,' to draw the links between health priorities, research priorities, existing evidence and missing evidence. Key causes of morbidity during labour and delivery in the United States include haemorrhage, pre-eclampsia and eclampsia, obstetric trauma and infection. Analyses of maternal morbidity and mortality suggest that key concerns include racial and ethnic disparities in health outcomes and the prevention of adverse events. Systematic reviews, however, generally tend to focus on the reduction of harms associated with interventions, are frequently limited to randomised designs, and do not address issues of health disparities. The results suggest that advances in evidence-based care in maternal health require that systematic reviews address issues of prevention of adverse events, include a larger variety of study designs when necessary and pay closer attention to health disparities.

Abstract
Participant-centered clinical research is essential for client-centered evidence-based health care in pregnancy. Breech malpresentation can obstruct labor, contributing to maternal mortality. This qualitative study of women's and providers' experience of breech led to five categories of themes related to participant-centered research: participation in this study, factors impeding women's participation, factors impeding clinical research, development of a participant-centered intervention, and improvement of a pregnancy research infrastructure. The findings contribute to understanding research participation during pregnancy. Gauging research protocols to fit questions of concern, women's and providers' experiences, and practice settings supports participant-centered pregnancy risk reduction research that could decrease maternal mortality.

Abstract
The results from an exploratory study of the effectiveness of maternal knee-chest posture for producing cephalic version of breech presentation are shown. Methods are briefly described and clinical implications are presented. Among 25 women, fewer who performed the maternal knee-chest postural intervention experienced fetal cephalic version than women in the control group who did nothing to influence breech presentation. Despite limitations of the underpowered findings, trends in the data may indicate that parity and gestational age were potentially relevant covariates of version. Postural management is not an evidence-based practice. This exploratory study indicates that maternal knee-chest posture may work opposite to the expected direction, but the small sample size precludes generalizations about efficacy of knee-chest postural management. At least one adequately powered trial that controls for parity and gestational age is needed to determine whether knee-chest postural management results in no effect, a small, or small to moderate clinically significant effect.
