Screening for gestational diabetes in pregnancy in Northwestern Ontario.

INTRODUCTION: We estimate the screening and prevalence of gestational diabetes mellitus (GDM) in a primarily first nations obstetrical population in Northwestern Ontario. METHODS: The study is an 8-year retrospective analysis of all gestational glucose challenge and tolerance tests performed at the Sioux Lookout Meno Ya Win Health Centre (SLMHC) laboratory from 1 January, 2010 to 31 December, 2017. Test, gestational timing and completion rate of screening were recorded, and GDM prevalence was calculated on the tested population. Screening completion rates were recorded for the subset of women who delivered at SLMHC from 2014 to 2017. RESULTS: The average annual GDM prevalence was 12%, double the Ontario rate. Over the 8-year period, 513 patients were diagnosed with GDM among the 4298 patients screened. Patients were screened with the 2-step (90%) or the 1-step (10%) protocol. Screening occurred <20 weeks in 3%; 54% occurred in <28 weeks and 40% >28 weeks. Seventy percent of the tests were from remote nursing stations. The screening completion rate for women delivering at SLMHC in 2017 was 80.8%. CONCLUSION: The prevalence of GDM in Northwestern Ontario is twice the provincial rate. Most screening used the 2-step protocol; early screening was underused. Improvements in screening programming are underway and future research may match surveillance rates and results to GDM outcomes.

Résumé Introduction: Nous estimons le dépistage et la prévalence du diabète gestationnel au sein d'une population obstétrique composée principalement de femmes des Premières Nations du Nord-Ouest de l'Ontario. Méthodologie: Il s'agissait d'une analyse rétrospective de 8 ans de toutes les épreuves d'hyperglycémie gestationnelle provoquée et de tous les tests de tolérance au glucose effectués au laboratoire Sioux Lookout Meno Ya Win Health Centre (SLMHC) entre le 1er janvier 2010 et le 31 décembre 2017. Le nombre de tests, le moment de la grossesse et le taux d'achèvement des tests de dépistage ont été consignés, et la prévalence du diabète gestationnel a été calculée dans la population testée. Le taux d'achèvement des tests de dépistage du sous-groupe de femmes ayant accouché au SLMHC entre 2014 et 2017 a aussi été consigné. Résultats: La prévalence annuelle moyenne de diabète gestationnel était de 12 %, soit le double de celle de l'Ontario. Durant les 8 ans qu'a duré l'étude, 513 patientes ont reçu un diagnostic de diabète gestationnel parmi les 4298 patientes soumises au dépistage. Le protocole à 2 étapes ou à 1 étape a servi au dépistage chez les patientes, à raison de respectivement 90 et 10 %. Le dépistage a eu lieu à < 20 semaines chez 3 %; à < 28 semaines chez 54 % et à > 28 semaines chez 40 % des patientes. Soixante-dix pour cent des tests ont été effectués dans des postes éloignés de soins infirmiers. Le taux d'achèvement du dépistage chez les femmes ayant accouché au SLMHC en 2017 était de 80,8 %. Conclusion: La prévalence de diabète gestationnel dans le Nord-Ouest de l'Ontario est le double du taux provincial. La plupart des tests effectués ont eu recours au protocole à 2 étapes; le dépistage précoce était sous-utilisé. L'on tente actuellement d'améliorer les programmes de dépistage, et de plus amples recherches pourraient documenter le taux de surveillance et approfondir notre compréhension des issues liées au diabète gestationnel.

Nonpharmacological management of neonatal abstinence syndrome: a review of the literature.

BACKGROUND: Infants with neonatal abstinence syndrome (NAS) experience withdrawal that occurs as a result of termination of placental opioid supply following delivery. Common symptoms include restlessness, tremors, agitation and gastrointestinal disturbances. Severe NAS is often treated using opioids and/or sedatives. Although commonly employed effectively in neonatal care, there is a lack of published information regarding nonpharmacological management of the NAS infant. OBJECTIVE: The purpose of this review was to summarize the current literature on nonpharmacological management of NAS. METHODS: A literature search of Medline and EMBASE was performed for articles published between 2000 and June 2107. RESULTS: Nonpharmacological management encompasses "environmental control", "feeding methods", "social integration", "soothing techniques" and "therapeutic modalities". Several interventions, including: breastfeeding, swaddling, rooming-in, environmental control and skin to skin contact have proven to be effective in managing NAS and should be incorporated into standard of care for this population (Level I-III Evidence). These interventions can be effective when offered in combination with pharmacological therapy, or as stand-alone therapy for less severe cases of NAS (Finnegan score <8). CONCLUSIONS: Given the increasing body of evidence on its efficacy and ease of implementation, nonpharmacological treatment should universally be incorporated into standard of care for NAS.

Maternal opioid use disorder and neonatal abstinence syndrome in northwest Ontario: a 7-year retrospective analysis.

INTRODUCTION: Opioid use in pregnancy is increasing globally. In northwest Ontario, rates of neonatal abstinence syndrome (NAS) are alarmingly high. We sought to document the increasing rates of opioid exposure during pregnancy and associated cases of NAS over a 7-year period in northwest Ontario. METHODS: We conducted a retrospective chart review at the Sioux Lookout Meno Ya Win Health Centre catchment area (population 29 000) maternity program in northwest Ontario of mother-infant dyads of live births from Jan. 1, 2009, to Dec. 31, 2015. The Integrated Pregnancy Program provides maternal, neonatal and addiction care for obstetrical patients at the health centre. We collected data on prenatal opioid exposure due to illicit and opioid agonist therapy (OAT) from patient/prescription histories and urine toxicology reports. Rates of NAS (diagnosed as a Finnegan score > 7) were recorded retrospectively from neonatal hospital charts. RESULTS: There were 2743 live births during the study period. Opioid exposure occurred in 672 pregnancies (335 OAT, 337 illicit). The incidence of prenatal opioid exposure increased significantly between 2009 and 2012 (11.1% to 28.5%, p < 0.001) but remained relatively constant at around 30% thereafter. Despite this, absolute rates of NAS remained relatively stable, with an average of 22.2 cases per 1000 live births over the study period. In comparison, the North West Local Health Integration Network (LHIN) experienced an average of 52.8 cases of NAS per 1000 live births in 2009-2012. The incidence of NAS in our centre decreased significantly over the study period (17.6% of opioid-exposed pregnancies in 2009 v. 4.0% in 2015, p = 0.001). There was a gradual transition toward a preponderance of OAT- versus illicit-exposed pregnancies, increasing from 0% in 2009 to 76.9% in 2015 (p < 0.001). CONCLUSION: Despite our continually increasing rates of opioid exposure in pregnancy, rates of NAS decreased annually and were substantially lower than those of our regional LHIN. In contrast to 2009, most opioid exposure in our region is now iatrogenic as a result of OAT. These improvements may be attributable in part to the rural community-based prenatal and addictions services developed in our catchment area.

INTRODUCTION: La consommation d'opioïdes pendant la grossesse est à la hausse dans le monde entier. Dans le nord-ouest de l'Ontario, le taux de syndrome de sevrage néonatal est alarmant. Nous avons tenté de documenter les taux croissants d'exposition aux opioïdes pendant la grossesse et les cas associés de syndrome de sevrage néonatal sur une période de sept ans dans le nord-ouest de l'Ontario. METHODS: Nous avons mené une étude rétrospective des dossiers des patientes du programme obstétrical de la région desservie par le Centre de santé Meno Ya Win de Sioux Lookout (population de 29 000), dans le nord-ouest de l'Ontario, et des naissances vivantes de la dyade mère­nourrisson pour la période du 1er janvier 2009 au 31 décembre 2015. Des soins maternels, néonataux et de traitement de la toxicomanie sont offerts aux patientes en obstétrique du Centre de santé dans le cadre d'un programme de soins intégrés pendant la grossesse. Nous avons obtenu des données sur l'exposition prénatale aux opioïdes due à la consommation d'opioïdes illégaux et aux traitements par agonistes opioïdes dans les antécédents des patientes, l'historique des médicaments prescrits et les rapports de toxicologie des dépistages urinaires. Le taux de syndrome de sevrage néonatal (diagnostiqué selon un score de Finnegan > 7) a été obtenu et consigné de manière rétrospective à partir des dossiers néonataux d'hôpitaux. RESULTS: Il y a eu 2743 naissances vivantes pendant la période de l'étude et 672 grossesses exposées aux opioïdes (335 aux traitements par agonistes opioïdes, 337 aux opioïdes illégaux). L'incidence de l'exposition prénatale aux opioïdes a augmenté de façon importante entre 2009 et 2012 (11,1 % à 28,5 %, p < 0,001), mais est ensuite demeurée relativement constante à environ 30 % par la suite. Malgré cela, le taux absolu de syndrome de sevrage néonatal est demeuré relativement stable, soit une moyenne de 22,2 cas par 1000 naissances vivantes pendant la période de l'étude. Par comparaison, le Réseau local d'intégration des services de santé (RLISS) du Nord-Ouest a enregistré une moyenne de 52,8 cas de syndrome de sevrage néonatal par 1000 naissances vivantes entre 2009 et 2012. L'incidence du syndrome de sevrage néonatal dans notre centre a diminué considérablement au cours de la période de l'étude (17,6 % de grossesses exposées aux opioïdes en 2009 contre 4 % en 2015, p = 0,001). Nous avons observé une transition graduelle vers la prépondérance des grossesses exposées aux traitements par agonistes opioïdes par rapport aux grossesses exposées aux opioïdes illégaux. Leur taux est passé de 0 % en 2009 à 76,9 % en 2015 (p < 0,001). CONCLUSION: Malgré la croissance continue de l'exposition aux opioïdes pendant la grossesse, notre taux de syndrome de sevrage néonatal a diminué annuellement et était nettement inférieur au taux du RLISS de la région. Par comparaison à 2009, la plupart des cas d'exposition aux opioïdes dans notre région sont maintenant d'origine iatrogène et liés aux traitements par agonistes opioïdes. Ces améliorations pourraient s'expliquer en partie par la création de services communautaires de soins prénataux et de traitement de la toxicomanie en régions rurales dans notre circonscription hospitalière.

Maternal-Fetal Monitoring of Opioid-Exposed Pregnancies: Analysis of a Pilot Community-Based Protocol and Review of the Literature.

OBJECTIVES: To describe/analyse a novel, community-based prenatal monitoring protocol for opioid-exposed pregnancies developed by our centre in 2014 to optimize prenatal care for this population. A literature review of published monitoring protocols for this population is also presented. METHODS: Retrospective comparison of pre-protocol (n = 215) and post-protocol (n = 251) cohorts. Medline and Embase were searched between 2000-2016 using MeSH terms: [fetal monitoring OR prenatal care] AND [opioid-related disorders OR substance-related disorders] in Medline and [fetal monitoring OR prenatal care] AND [opiate addiction OR substance abuse] in Embase, producing 518 results. Thirteen studies included protocols for monitoring opioid-exposed pregnancies. No comprehensive monitoring protocols with high-quality supporting evidence were found. RESULTS: We evaluated 466 opioid-exposed pregnancies, 215 before and 251 after introduction of the protocol. Since implementation, there was a significant increase in the number of opioid-exposed patients who have underwent urine drug screening (72.6% to 89.2%, P < 0.0001); a significant reduction in the number of urine drug screenings positive for illicit opioids (50.2% to 29.1%, P < 0.0001); and a significant increase in the number of patients who discontinued illicit opioid use by the time of delivery (24.7% to 39.4%, P < 0.01). There was no difference in the CS rate (27.4% vs. 26.3%, P > 0.05). There were no observed differences in the rate of preterm birth, birth weight <2500 g, or Apgar score <7 (P > 0.05). CONCLUSIONS: Care of women with increased opioid use during pregnancy is an important but under-studied health issue. A novel protocol for focused antenatal care provision for women with opioid-exposed pregnancies improves standard of care and maternal/fetal outcomes.

Narcotic tapering in pregnancy using long-acting morphine: an 18-month prospective cohort study in northwestern Ontario.

OBJECTIVE: To document the management of and outcomes for patients receiving narcotic replacement and tapering with long-acting morphine preparations during pregnancy. DESIGN: A prospective cohort study over 18 months. SETTING: Northwestern Ontario. PARTICIPANTS: All 600 births at Meno Ya Win Health Centre in Sioux Lookout, Ont, from January 1, 2012, to June 30, 2013, including 166 narcotic-exposed pregnancies. INTERVENTION: Narcotic replacement and tapering of narcotic use with long-acting morphine preparations. MAIN OUTCOME MEASURES: Prenatal management of maternal narcotic use, incidence of neonatal abstinence syndrome, and other neonatal outcomes. RESULTS: The incidence of neonatal abstinence syndrome fell significantly to 18.1% of pregnancies exposed to narcotics (from 29.5% in a previous 2010 study, P = .003) among patients using narcotic replacement and tapering with long-acting morphine preparations. Neonatal outcomes were otherwise equivalent to those of the nonexposed pregnancies. CONCLUSION: In many patients, long-acting morphine preparations can be safely used and tapered in pregnancy, with a subsequent decrease in observed neonatal withdrawal symptoms.

Incidence of narcotic abuse during pregnancy in northwestern Ontario: three-year prospective cohort study.

OBJECTIVE: To document the incidence and outcomes of narcotic use during pregnancy in northwestern Ontario. DESIGN: Three-year prospective cohort study. SETTING: Sioux Lookout and surrounding communities in northwestern Ontario. PARTICIPANTS: A total of 1206 consecutive births in a catchment area of 28 000 First Nations patients. MAIN OUTCOME MEASURES: Incidence of narcotic use, and maternal and neonatal outcomes. RESULTS: Incidence of narcotic use in pregnancy has risen to 28.6% (P < .001) and incidence of neonatal abstinence syndrome has fallen to 18.0% of narcotic-exposed births (P = .003). Daily intravenous drug use is now a common pattern of abuse. CONCLUSION: Narcotic abuse in pregnancy has dramatically increased in northwestern Ontario. Neonatal outcomes have improved as a result of a family medicine-based prenatal and obstetric program that includes a narcotic replacement and tapering program.

Narcotic-exposed neonates in a First Nations population in northwestern Ontario: incidence and implications.

OBJECTIVE: To document the incidence of neonatal abstinence syndrome (NAS) and the rate of narcotic use during pregnancy in northwestern Ontario, where narcotic abuse is a growing social and medical problem. DESIGN: Retrospective chart review. SETTING: The Sioux Lookout Meno Ya Win Health Centre catchment area in northwestern Ontario. PARTICIPANTS: Mothers and neonates for the 482 live births that took place in the 18-month study period (January 2009 to June 2010). MAIN OUTCOME MEASURES: Maternal drug use and neonatal outcomes were documented. RESULTS: The incidence of narcotic (oxycodone) abuse during pregnancy increased from a low of 8.4% at the beginning of the study period to a high of 17.2% by mid-2010. Narcotic-using mothers were more likely to also use nicotine and alcohol, to have premature deliveries, and to be episodic users. Narcotic-exposed neonates experienced NAS 29.5% of the time; daily maternal use was associated with a higher rate of NAS (66.0%). While all infants roomed in with their mothers, exposed infants were more likely to require transfer to a tertiary care nursery. Infants with severe NAS were treated with oral morphine and had significantly longer hospital stays compared with the entire cohort (4.5 vs 1.5 days, P = .004). Narcotic abuse during pregnancy in our region is not currently associated with increased rates of HIV or hepatitis C infection, as intravenous route of administration is less common at present than intranasal and oral ingestion. CONCLUSION: Narcotic abuse during pregnancy is a considerable problem in First Nations communities in northwestern Ontario. Community-based initiatives need to be developed to address this issue, and medical and nursing staff need to develop surveillance, assessment, and therapeutic responses. Passive neonatal addiction and withdrawal result from maternal narcotic use during pregnancy. Rates of opioid use among pregnant Canadian women are unknown.

The choking game and YouTube: a dangerous combination.

PURPOSE: To study postings of partial asphyxiation by adolescents on YouTube and to increase awareness of this dangerous activity as well as the value of YouTube as a research tool. METHODS: Videos were searched on YouTube using many terms for recreational partial asphyxiation. Data were gathered on the participants and on the occurrence of hypoxic seizure. RESULTS: Sixty-five videos of the asphyxiation game were identified. Most (90%) participants were male. A variety of techniques were used. Hypoxic seizures were witnessed in 55% of videos, but occurred in 88% of videos that employed the "sleeper hold" technique. The videos were collectively viewed 173550 times on YouTube. CONCLUSIONS: YouTube has enabled millions of young people to watch videos of the "choking game" and other dangerous activities. Seeing videos may normalize the behavior among adolescents. Increased awareness of this activity may prevent some youths from participating and potentially harming themselves or others.

Long-term outcome is unchanged by antiepileptic drug treatment after a first seizure: a 15-year follow-up from a randomized trial in childhood.

PURPOSE: In 1989 we reported that 1 year of daily treatment with carbamazepine (CBZ) significantly reduced the recurrence rate after a first afebrile seizure in children compared with no treatment in a randomized open trial. We sought to determine if the long-term clinical course and rate of remission were changed by treatment starting after the first seizure. METHODS: Participants of the original trial (14 CBZ, 17 no medication) were contacted in 2001. RESULTS: Sixteen controls and 10 CBZ (84%) cases were followed up for 15 years. After randomization and follow-up, 12 controls and five treated patients had at least one more seizure (p = NS). For those with recurrences, the number of recurrences appeared to be the same in both groups. Number of medications used was also the same. Terminal remission (>2 years seizure free with or without medication) was achieved by eight (80%) of 10 CBZ and 14 (88%) of 16 controls, and terminal remission off medication in six (60%) of 10 CBZ (p = NS). CONCLUSIONS: Based on this small study with long follow-up, it appears that for children treated with CBZ after a first seizure, the subsequent clinical course and remission rates are not improved in comparison with a no-treatment strategy. Delaying treatment after a first seizure appears defensible.
