Modifying maternal sleep position in the third trimester of pregnancy with positional therapy: a randomised pilot trial.

OBJECTIVE: To evaluate whether the percentage of time spent supine during sleep in the third trimester of pregnancy could be reduced using a positional therapy device (PrenaBelt) compared with a sham device. DESIGN: A double-blind, randomised, sham-controlled, cross-over pilot trial. SETTING: Conducted between March 2016 and January 2017, at a single, tertiary-level centre in Canada. PARTICIPANTS: 23 participants entered the study. 20 participants completed the study. Participants were low-risk, singleton, third-trimester pregnant women aged 18 years and older with body mass index <35 kg/m2 at the first antenatal appointment for the index pregnancy and without known fetal abnormalities, pregnancy complications or medical conditions complicating sleep. INTERVENTIONS: A two-night, polysomnography study in a sleep laboratory. Participants were randomised by computer-generated, one-to-one, simple randomisation to receive either a PrenaBelt or a sham-PrenaBelt on the first night and were crossed over to the alternate device on the second night. Allocation concealment was by unmarked, security-tinted, sealed envelopes. Participants, the recruiter and personnel involved in setting up, conducting, scoring and interpreting the polysomnogram were blinded to allocation. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the percentage of time spent supine during sleep. Secondary outcomes included maternal sleep architecture, respiration, self-reported sleep position and feedback. RESULTS: The median percentage of sleep time supine was reduced from 16.4% on the sham night to 3.5% on the PrenaBelt night (pseudomedian=5.8, p=0.03). We were unable to demonstrate differences in sleep architecture or respiration. Participants underestimated the time they spent sleeping supine by 7.0%, and six (30%) participants indicated they would make changes to the PrenaBelt. There were no harms in this study. CONCLUSIONS: This study demonstrates that the percentage of sleep time supine during late pregnancy can be significantly reduced via positional therapy.

Global Women's Health Education in Canadian Obstetrics and Gynaecology Residency Programs: A Survey of Program Directors and Senior Residents.

OBJECTIVE: To become culturally competent practitioners with the ability to care and advocate for vulnerable populations, residents must be educated in global health priorities. In the field of obstetrics and gynaecology, there is minimal information about global women's health (GWH) education and interest within residency programs. We wished to determine within obstetrics and gynaecology residency programs across Canada: (1) current GWH teaching and support, (2) the importance of GWH to residents and program directors, and (3) the level of interest in a national postgraduate GWH curriculum. METHODS: We conducted an online survey across Canada of obstetrics and gynaecology residency program directors and senior obstetrics and gynaecology residents. RESULTS: Of 297 residents, 101 (34.0%) responded to the survey and 76 (26%) completed the full survey. Eleven of 16 program directors (68.8%) responded and 10/16 (62.5%) provided complete responses. Four of 11 programs (36.4%) had a GWH curriculum, 2/11 (18.2%) had a GWH budget, and 4/11 (36.4%) had a GWH chairperson. Nine of 10 program directors (90%) and 68/79 residents (86.1%) felt that an understanding of GWH issues is important for all Canadian obstetrics and gynaecology trainees. Only 1/10 program directors (10%) and 11/79 residents (13.9%) felt that their program offered sufficient education in these issues. Of residents in programs with a GWH curriculum, 12/19 (63.2%) felt that residents in their program who did not undertake an international elective would still learn about GWH, versus only 9/50 residents (18.0%) in programs without a curriculum (P < 0.001). CONCLUSION: Obstetrics and gynaecology residents and program directors feel that GWH education is important for all trainees and is currently insufficient. There is a high level of interest in a national postgraduate GWH educational module.

Objective: Pour devenir des praticiens compétents sur le plan culturel étant en mesure de prodiguer des soins aux populations vulnérables et de défendre leur cause, les résidents doivent recevoir une formation abordant les priorités de la santé à l'échelle mondiale. Dans le domaine de l'obstétrique-gynécologie, nous ne disposons que de peu de renseignements au sujet de la formation en santé des femmes à l'échelle mondiale (SFEM) qu'offrent les programmes de résidence et de l'intérêt envers ce type de formation que l'on y constate. Nous souhaitions déterminer ce qui suit en ce qui concerne les programmes canadiens de résidence en obstétrique-gynécologie : (1) la situation actuelle pour ce qui est de l'enseignement de la SFEM et du soutien disponible à cet égard; (2) l'importance de la SFEM pour les résidents et les directeurs de programme; et (3) le degré d'intérêt envers un curriculum national de cycle supérieur dans le domaine de la SFEM. Méthodes : Nous avons mené, à l'échelle du Canada, un sondage en ligne auprès des directeurs des programmes de résidence en obstétrique-gynécologie et des résidents de dernière année du domaine. Résultats : Parmi les 297 résidents sollicités, 101 (34,0 %) ont répondu au sondage et 76 (26 %) ont rempli le sondage en entier. Onze des 16 directeurs de programme sollicités (68,8 %) ont répondu et 10/16 (62,5 %) nous ont fourni des réponses complètes. Quatre des 11 programmes (36,4 %) comptaient un curriculum de SFEM, 2/11 (18,2 %) comptaient un budget de SFEM et 4/11 (36,4 %) comptaient un président de la SFEM. Neuf directeurs de programme sur 10 (90 %) et 68 résidents sur 79 (86,1 %) étaient d'avis qu'une compréhension des questions de SFEM est importante pour tous les stagiaires canadiens en obstétrique-gynécologie. Seulement un directeur de programme sur 10 (10 %) et 11 résidents sur 79 (13,9 %) étaient d'avis que leur programme offrait une formation suffisante sur ces questions. Parmi les résidents des programmes comptant un curriculum de SFEM, 12/19 (63,2 %) étaient d'avis que les résidents de leur programme qui n'entreprenaient pas un stage au choix international auraient tout de même l'occasion de se sensibiliser à la SFEM, par comparaison avec seulement neuf des 50 résidents (18,0 %) des programmes ne comptant pas un tel curriculum (P < 0,001). Conclusion : Les résidents et les directeurs de programme du domaine de l'obstétrique-gynécologie estiment que la formation au sujet de la SFEM est importante pour tous les stagiaires et qu'elle est actuellement insuffisante. La mise sur pied d'un module pédagogique national de cycle supérieur en SFEM suscite un vif intérêt.

Late preterm delivery in women with preterm prelabour rupture of membranes.

OBJECTIVE: To estimate maternal and neonatal outcomes in women with preterm prelabour rupture of membranes (PPROM) who delivered at 34+0 to 36+6 weeks' gestation, particularly in those who had an obstetrically indicated delivery. METHODS: We conducted a population-based study of late preterm singleton births complicated by PPROM, using data from the Nova Scotia Atlee Perinatal Database from 1988 to 2006. The study cohort was categorized by type of labour (spontaneous, induced, no labour), and each group's characteristics prior to delivery, and their outcomes were compared after accounting for potential confounding variables. RESULTS: From a total population of 164 384 pregnancies, 2618 deliveries were identified as having PPROM. Among these, 2180 (83.3%) delivered between 34+0 and 36+6 weeks' gestation. Adjusted analyses showed no differences in risk between those women entering labour spontaneously (n = 1296) and those with obstetrically indicated delivery (labour induction or Caesarean section without labour, n = 698). Additional adjusted analyses evaluating only women with obstetrically indicated delivery showed that rates of chorioamnionitis (OR 0.27; 95% CI 0.08 to 0.93), composite perinatal morbidity/mortality (OR 0.39; 95% CI 0.25 to 0.62), neonatal depression at birth (OR 0.22; 95% CI 0.06 to 0.86), and respiratory distress syndrome (OR 0.17; 95% CI 0.06 to 0.47) were significantly lower in those delivering at 36 weeks (n = 458) than in those delivering at 34 to 35 weeks (n = 240). CONCLUSIONS: This large population-based study suggests that in pregnancies complicated by PPROM rates of adverse maternal and perinatal outcomes at 36 weeks' gestational age are at least comparable to those in pregnancies delivering at 34 to 35 weeks, and these rates may be further reduced by delivery after 36 completed weeks if spontaneous labour has not occurred.
