[Clinical research in the home as a tool for improving practice]

The quality of life in hospital at home has been very little described. In the "Feel'HAD" study, 488 patients completed an EQ-5D-3L questionnaire during a nursing visit. Neurological and geriatric pathologies were found to be the most degraded, even if there were strong disparities within the different types of conditions. This work has shown that beyond technical care, some people need more support, psychological care, comfort or social support. It led to concrete improvements in our practices and demonstrated that large-scale research is possible in the home.

Incidence of maternal and fetal outcomes in women with gestational diabetes

INTRODUCTION

Gestational diabetes mellitus (GDM) is associated with both maternal and fetal complications related to maternal hyperglycemia.

AIM

The aim of the study was to describe the incidence of maternal and fetal complications associated with GDM in a reference maternity hospital in the Tunis (2019-2020).

METHODS

We conducted a prospective longitudinal descriptive and analytical study including 220 patients followed for GDM at the research unit «Diabetes and pregnancy» of the C department of the National Institute of Nutrition of Tunis. The patients were followed during pregnancy and until post partum, for a period of 18 months (July 2019-December 2020). The patients were divided into two groups Group1(G1) including women treated with insulin therapy (n=68) and Group 2(G2) including women treated with diet only (n=152).

RESULTS

In the current study, 63,6% of patients delivered by cesarean section and 5% developed gestational induced hypertension. Neonatal outcomes were dominated by macrosomia (13.5%) and transient respiratory distress (11.4%). Insulin-treated women had a higher incidence of gestational induced hypertension (G1:11,9% versus G2: 2,1%;p=0,03). There was no significant difference between the two groups in the incidence of fetal outcomes including macrosomia (G1:17.6% versus G2:11.2%; p=0.203),transient respiratory distress (G1:11.8% versus G2: 10.5%; p=0.781) and prematurity (G1:7.4% versus G2:4.6%; p=0.452).

CONCLUSION

Our study showed that Insulin-treated women had a higher incidence of gestational induced hypertension. However, there was no significant difference between the two groups in the incidence of fetal complications.

Identifiable Dietary Patterns of Pregnant Women: A Canadian Sample

Purpose: To estimate the percentage of a sample of pregnant women in Canada following a vegetarian, vegan, low-carbohydrate, gluten-free, Mediterranean, or well-balanced diet, before and during pregnancy and to explore if pregnant women received and were satisfied with nutrition information received from health care providers (HCPs).Methods: Participants were conveniently sampled through Facebook and Twitter. An online survey collected data on sociodemographic characteristics, maternal diet, and whether women received and were satisfied with nutrition information from their HCPs. The McNemar test assessed changes in the proportion of diets followed before and during pregnancy.Results: Of 226 women, most followed a well-balanced diet before (76.9%) and during (72.9%) pregnancy (p = 0.26). Vegetarian, gluten-free, vegan, and low-carbohydrate diets were the least followed diets before and during pregnancy (vegetarian: 7.6% vs 5.3%; gluten-free: 4.9% vs 4.0%; vegan: 2.7% vs 2.2%; low-carbohydrate:4.0% vs 0.4%). Overall, the number of women following restrictive diets before pregnancy was significantly reduced throughout pregnancy (19.1% vs 12.0%, p < 0.001). Only 52.0% of women received nutrition information from their primary HCP, and 35.6% were satisfied with the nutrition information received.Conclusions: Most women followed a well-balanced diet before and during pregnancy and approximately one-third were satisfied with the information received from HCPs.

Acute fetal response to high-intensity interval training in the second and third trimesters of pregnancy

The majority of women do not meet the recommended levels of exercise during their pregnancies, frequently due to a lack of time. High-intensity interval training offers a potential solution, providing an effective, time-efficient exercise modality. This exercise modality has not been studied in pregnancy therefore, the objective of this study was to evaluate fetal response to a high-intensity interval training resistance circuit in the late second and early third trimesters of pregnancy. Fourteen active, healthy women with uncomplicated, singleton pregnancies participated in a high-intensity interval training resistance circuit between 28 + 0/7 and 32 + 0/7 weeks. A Borg rating of perceived exertion of 15-17/20 and an estimated heart rate of 80%-90% of maternal heart-rate maximum was targeted. Fetal well-being was evaluated continuously with fetal heart-rate tracings and umbilical artery Doppler velocimetry conducted pre-and post-exercise. Fetal heart rate tracings were normal throughout the exercise circuit. Post-exercise, umbilical artery end-diastolic flow was normal and significant decreases were observed in the mean systolic/diastolic ratios, pulsatility indexes and resistance indexes. Therefore, in a small cohort of active pregnant women, a high-intensity interval training resistance circuit in the late second and early third trimesters of pregnancy appears to be a safe exercise modality with no acute, adverse fetal effects but further study is required. Novelty: High-intensity interval training, at an intensity in excess of current recommendations, does not appear to be associated with any adverse fetal effects in previously active pregnant women. High-intensity interval training is an enjoyable and effective exercise modality in previously active pregnant women.

The autonomous choice of delivery mode: A survey of Tunisian women

BACKGROUND

The recent overmedication of childbirth process ignores mothers wishes.  In Tunisia, women are not involved in decision-making during childbirth.

AIM

To analyze the opinion of a sample of Tunisian women regarding the possibility of making their own informed choices during childbirth and to determine the factors that may influence the requested mode of delivery.

METHODS

This was a 5-month descriptive cross-sectional survey. Were included: Tunisian women who were consultants or practitioners at a university obstetrics and gynaecology department in Tunis; female medicine students or members of women dedicated social network groups. The questionnaire was applied during direct interviews or posted online. The main judgment criteria was: participants' opinion regarding access to autonomous choice of delivery mode. Participants were initially enrolled into 2 groups: •    group of women requesting access to autonomous choice. •    group of women who do not request access to autonomous choice.  The participants were then divided into 2 other groups according to the requested mode of delivery: •    Group : Cesarean section •    Group: Vaginal delivery. A multivariate logistic regression was used to identify risk factors that may have influenced the responses.

RESULTS

The total number of participants was 197. Access to autonomous choice was requested by 63.45% of the participants. These were mainly: consultants: OR=7.76 95% CI [0.56-106.16] or practitioners: OR=3.93 95% CI [0.01-829.03], with a high level of education OR=1.22 95% CI [0-1174.40], with a past positive birth experience: OR=1.24 95% CI [0.27-5.74]. The women who did not claim access to autonomous choices were mainly: doctors OR=-0.31 95% CI [0-32.58], midwives: OR=-0.08, 95% CI [0-18.12] or even housewives OR=-0.42 95% CI [0-68.88]. The women who preferred to give birth by Caesarean section were mainly: practitioners: OR=2.03 95% CI [0.53-7.81], nulliparous OR=2.51 95% CI [0.243-25.98], pregnant OR= 4.44 95% CI [1.03-19.13], with a history of cesarean delivery: OR=5.68 95% CI [0.64- 50.43] or even a history of negative childbirth experience: OR=1.87 95% CI [0.22-15.85].

CONCLUSION

The request for an Autonomous choice during childbirth most often expresses a certain number of beliefs and fears. Obstetricians should take time to listen and explain, in order to understand the mother's anxieties and enable her to resolve them. Based on the principles of justice, the access to autonomous choices during childbirth process should be universally recognized by legislations and thus fairly respected for all.

Present as a partner and a parent: Mothers' and fathers' perspectives on father participation in prenatal care

Supportive father involvement during pregnancy can positively impact maternal and child outcomes. Father participation in prenatal care is increasing, yet little research exists to understand how mothers and fathers experience father participation in prenatal care and their preferences for father participation. We interviewed expectant first-time mothers (N = 22) and fathers (N = 20) to learn about fathers' participation in prenatal care, perceptions of providers' treatment of fathers, and preferences for father participation. Interviews were coded using principles of grounded theory. Father participation ranged from attendance at visits considered "important" (e.g., ultrasounds) to attendance at every appointment. Experiences of father participation varied, with many describing it as both an important act of support for the mother and part of assuming the role of father. Most participants saw great value in father participation in prenatal care as an opportunity for fathers to learn how to support a healthy pregnancy, bond with their developing baby, and share joy and/or worries with mothers. Participants generally felt that fathers were made to feel welcome and wanted providers to be inclusive of fathers during appointments. Results of this study suggest that father participation presents an opportunity for prenatal care providers to foster fathers' positive involvement in pregnancy, support for mothers, and preparation to parent.

Role of pregnancy on insulin-induced vasorelaxation: the influence of angiotensin II receptors

Insulin resistance is a feature of pregnancy and is associated with increased levels of angiotensin II (Ang II) and insulin. Therefore, pregnancy may change insulin-induced vasodilation through changes in Ang II receptors. Insulin-induced vasorelaxation was evaluated in phenylephrine-precontracted aortic rings of pregnant and non-pregnant rats, using a conventional isolated organ preparation. Experiments were performed in thoracic or abdominal aorta rings with or without endothelium in the presence and absence of N^G-nitro-L-arginine methyl ester (L-NAME) (10^-5 M), losartan (10^-7 M), or PD123319 (10^-7 M). AT1 and AT2 receptor expressions were detected by immunohistochemistry. Insulin-induced vasodilation was endothelium- and nitric oxide-dependent and decreased in the thoracic aorta but increased in the abdominal segment of pregnant rats. The insulin's vasorelaxant effect was increased by losartan mainly on the thoracic aorta. PD123319 decreased insulin-induced vasorelaxation mainly in the pregnant rat abdominal aorta. AT1 receptor expression was decreased while AT2 receptor expression was increased by pregnancy. In conclusion, pregnancy changes insulin-induced vasorelaxation. Moreover, insulin vasodilation is tonically inhibited by AT1 receptors, while AT2 receptors appear to have an insulin-sensitizing effect. The role of pregnancy and Ang II receptors differ depending on the aorta segment. These results shed light on the role of pregnancy and Ang II receptors on the regulation of insulin-mediated vasodilation.

[Fathers' imaginations during ultrasound scans in pregnancy]

Ante-natal consultations are major places of prevention, with regard to the psychological vulnerabilities of "becoming parents" specific to the pregnancy period. A study was carried out on future fathers and their impressions of ultrasound examinations. Men's impulsive ambivalence towards pregnancy is the main subject of this research, which shows how ultrasound scans are a place for exploring these impulsive movements of fathers.

The Power of Small Conversations: Bridging the Gap Between Diabetes and Pregnancy Planning

Despite the established importance of preconception counselling among women with pre-existing diabetes, many Canadian women of this demographic continue to report inadequate medical planning of pregnancy. Primarily due to the teratogenic effects of hyperglycemia in the early weeks of pregnancy, minimizing the risk of adverse pregnancy outcomes requires a proactive approach toward medical optimization before conception. Primary care providers are well placed to provide preconception counselling to reproductive age women with pre-existing diabetes to alert them to the importance of pregnancy planning. This counselling may not necessarily require dedicated visits but may take the form of simple check-ins and key messages interspaced between other interactions. Herein we discuss the importance and challenges of preconception counselling among women with pre-existing diabetes and provide a pragmatic approach to the delivery of preconception counselling among primary care providers.

OBJECTIVE

Examine the association between news media use frequency during the COVID-19 pandemic and the scale of psychological distress in pregnant women, considering this distress known harmful effects on the fetus development.

METHOD

Pregnant women living in Quebec province (N = 1014) have been recruited in April 2020 through social media, while a state of health emergency was declared. Participants were divided in 4 groups, according to self-reported frequency of news media consulting (little or none; one time a day; several times a day; constant). They filled measures of depressive symptoms, negative affects, post-traumatic stress symptoms and anxiety specific to COVID-19. Instrument scores were grouped under a unique factor of psychological distress.

RESULTS

An ANCOVA controlling for age, gestational age, education level, household annual revenue and a diagnosed mental disorder present at the time of participation in study shows that news media exposure frequency is significantly associated with psychological distress severity in pregnant women, during COVID-19 pandemic, F(3,998) = 27.02, p < 0.001, η2 partial = 0.08. Given the mean comparisons a posteriori, higher psychological distress rates are found as soon as news media exposure exceeds once a day (effect sizes between 0.38 and 0.81).

CONCLUSIONS

The more pregnant women report consulting the news media during the COVID-19 pandemic, the more likely they are to exhibit psychological distress. Results provide one of the first empirical supports to recommendations of World Health Organization, Canada government and psychiatric associations that encourage population to limit their news media consulting during the COVID-19 pandemic.

An animal model of gestational obesity and prediabetes: HISS-dependent insulin resistance induced by a high-sucrose diet in Sprague Dawley rats

This study developed an animal model of gestational obesity and prediabetes in Sprague Dawley rats using 35% sucrose supplementation (SS). Postprandially, insulin stimulates glucose uptake and nutrient partitioning via insulin-dependent action as well as hepatic insulin sensitizing substance (HISS) - dependent action. HISS is glycogenic in heart, kidney, and skeletal muscle (contrasting insulin's lipogenic actions in liver and adipose tissue) and is responsible for the vasodilatory action of insulin. Postprandial insulin sensitivity was quantified using the rapid insulin sensitivity test (RIST). Animals at 15-day gestation and virgin animals received SS for 8 weeks (with a 2-week recovery), 10 weeks, or 22 weeks. SS in pregnant and virgin rats eliminated HISS-dependent glucose uptake, resulting in compensatory hyperinsulinemia and resultant hypertriglyceridemia and obesity. In groups with SS for 8 weeks followed by a 2-week recovery, there was spontaneous partial recovery of HISS-dependent glucose uptake in virgins and complete recovery in pregnancy. The 10-week SS resulted in complete absence of HISS-dependent glucose uptake and produced a model of gestational obesity and prediabetes. The 22-week SS did not produce hyperglycemia or worsen hyperinsulinemia but did increase hypertriglyceridemia above 10-week SS. This substantiates the use of 10-week SS as a model of gestational obesity and (or) prediabetes, allowing further studies into treatments of gestational obesity and insulin resistance.

The quality of physical activity guidelines, but not the specificity of their recommendations, has improved over time: a systematic review and critical appraisal

While numerous guidelines for the prescription of physical activity are released each year, the quality and practicability of these guidelines is unknown. We assessed the quality of 95 guidance documents published since 2000 that included recommendations about physical activity for the promotion of general health and prevention of cardiometabolic disease. We used 3 tools: Appraisal of Guidelines for Research and Evaluation (AGREE II), the National Academy of Medicine's (NAM) Standards for Trustworthy Clinical Practice Guidelines, and the Frequency, Intensity, Time, and Type (FITT) score. Average AGREE II domain scores ranged from 38%-84%, and the portion of criteria fulfilled per NAM domain ranged from 7%-39%. The average FITT score for all recommendations was 2.48 out of 4. While guidelines improved according to both AGREE II and the NAM standards over time, their practicability as assessed by FITT score did not improve. Guidelines produced by governmental agencies or other nonprofit organizations, using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach, or fulfilling a higher number of NAM criteria tended to be of higher quality. Organizations producing physical activity guidelines can improve their quality by establishing and reporting processes for public representation, external review, and conflict of interest (COI) management. Future recommendations about physical activity should be more specific and include strategies to improve implementation. Registration no.: PROSPERO CRD42019126364. Novelty: Most physical activity recommendations are not sufficiently specific to be practically implemented. The overall quality of guidelines has improved over time, but the specificity of recommendations has not. Improved public representation, external review, and COI disclosure and management processes would improve guideline quality.

Development and Evaluation of a CT Pulmonary Angiography Protocol Dedicated to Pregnant and Postpartum Women

INTRODUCTION

This study presents and evaluates a CT pulmonary angiography protocol dedicated to pregnant women. The specific feature of this protocol is to place the region of interest (ROI) (bolus detection) in the superior vena cava. The objective is to evaluate the performances of this method.

MATERIALS AND METHODS

The protocol uses a iodine-based contrast agent at 300mgI/mL and an injection rate of 5 to 6 mL/sec for an injection volume of 50 mL of iodine contrast agent followed by 40 mL of NaCl. The ROI is positioned on the superior vena cava, with a 100 Hounsfield units (HU) threshold, and the acquisition is performed at 100 kVp. This protocol was evaluated retrospectively on a large population (n = 105: group 1) and compared with a control group that did not benefit from this protocol (n = 55: group 2). Both groups were studied on the same device in the same center. Each examination was evaluated and classified into 3 groups: optimal, suboptimal, and noncontributory. Dose length products (DLP) values were also recorded. Statistical tests were applied to the data collected.

RESULTS

The rate of noncontributory examinations increased from 43.1% for the control group to 4.8% for the new protocol group. The reference enhancement level in the pulmonary trunk is 250 UH. The mean enhancement in the pulmonary trunk of the new protocol group (332 HU (±71 HU (±71 HU)) is significantly greater than the reference value of 250 HU (P < .0001), which is not the case for control group (P = .3485 > .05), which has a mean enhancement of 239 HU (±87 HU). The control group had a mean DLP of 225 mGy.cm (±81 mGy.cm), and the new-protocol group had a mean DLP of 189 mGy.cm (±75 mGy.cm).

DISCUSSION

Our noncontributory examination rate is the lowest rate described in the literature. Our protocol contradicts standard practices of placing an ROI in the pulmonary trunk for bolus detection of iodinated contrast media.

CONCLUSION

The results of this study showed that this protocol reduces the number of noncontributory examinations while reducing the dose delivered to patients. This robust protocol is applicable to other devices and meets perfectly radiation-safety requirements and injected contrast media volume limitation.

[Becoming parents in a cross-cultural situation]

Being parents is an adventure in itself. Being parents in a cross-cultural situation, in exile, away from family and friends, is a double challenge. Today, we know more about the risks and the potential. Let's explore the key ingredients for early childhood: how to live through pregnancy, welcoming the child, being father and mother, building a family in our own way by blending it with local ways of doing things, a more or less hospitable land of welcome. This is followed by a set of guidelines for all the professionals who intervene at this crucial period to build the parent-child bond.

Micro-elimination of hepatitis C through testing of Egyptian pregnant women presenting at delivery: implications for screening policies

OBJECTIVES

Despite the high burden of hepatitis C virus (HCV) infection in Egypt, screening of pregnant women is not yet universal, making national and global elimination unlikely. This study assessed the proportion of pregnant women who were screened for HCV infection at delivery, the prevalence and risk factors for HCV infection, the associated adverse neonatal outcomes, and the real-life linkage to care of infected women and follow-up of their infants' HCV status and timing of testing.

METHODS

Data were collected from medical records of a retrospective cohort of all pregnant women who were admitted to a university hospital in Cairo for delivery between January and June 2018 (n = 6734). HCV antibody- and RNA-positive women and their infants were prospectively followed-up by phone interviews till September 2019.

RESULTS

2177 (32.3%) pregnant women were screened for HCV infection. 19 (0.9%) tested HCV antibody- and RNA-positive. Being ≥ 30 years old (ORa 3.6, 95% CI: 1.4-9.2; P = 0.009), history of abortion (ORa 3.5, 95% CI: 1.2-10.3; P = 0.022) and blood transfusion (ORa 29.1, 95% CI: 9.6-88.4; P < 0.001) were independent risk factors for infection. Adverse neonatal outcomes did not vary significantly among HCV antibody-positive and antibody-negative women. Only 13 (68.4%) HCV antibody- and RNA-positive women started treatment with direct-acting antivirals (DAAs) post-breastfeeding (two completed the treatment course and were cured). Four (21.1%) did not start treatment, and two (10.5%) were lost to follow-up. All infants of the 13 HCV antibody- and RNA-positive women who started DAA therapy tested HCV RNA-negative within their first year of life.

CONCLUSION

Extending screening services to all pregnant women and better linkage to care are essential for the national elimination of HCV infection.

Gestational postprandial insulin sensitivity in the Sprague Dawley rat: the putative role of hepatic insulin sensitizing substance in glucose partitioning in pregnancy

Pregnancy requires adaptation of maternal insulin sensitivity. In the fed state, a pulse of insulin stimulates glucose uptake and nutrient energy storage via insulin-dependent as well as hepatic insulin sensitizing substance (HISS)-dependent action. HISS is released by the liver in the fed state in the presence of signals integrated through the liver and a pulse of insulin. HISS promotes glucose storage as glycogen in heart, kidney, and skeletal muscle but not in gut, liver, or adipose tissue. HISS is also responsible for the vasodilatory action previously attributed to insulin. The rapid insulin sensitivity test (RIST), a dynamic euglycemic clamp, can quantitate both HISS-dependent and insulin-dependent glucose uptake. The RIST was used to characterize postprandial insulin sensitivity in the Sprague Dawley rat and the changes in the partitioning of nutrient energy throughout gestation. Early pregnancy demonstrated increased insulin sensitivity attributable to HISS-dependent glucose uptake with unchanged insulin-dependent glucose uptake, preserved plasma insulin concentration, and reduced plasma triglyceride concentration compared to the virgin. In late pregnancy, there was reduced HISS-dependent and insulin-dependent glucose uptake accompanied by increased plasma insulin and triglyceride concentration compared to the virgin. These results suggest an important role for HISS in glucose partitioning in pregnancy.

Cycling reduces blood glucose excursions after an oral glucose tolerance test in pregnant women: a randomized crossover trial

The aim of this study was to evaluate the effect of an acute bout of cycling immediately after oral glucose intake on glucose metabolism in pregnant women at risk for gestational diabetes mellitus (GDM). Fifteen pregnant women with BMI ≥ 27 kg/m² were enrolled in a randomized crossover controlled study and underwent two oral glucose tolerance tests (OGTTs) ingesting 75 g of glucose followed by either 20 min of stationary cycling at moderate intensity (65%-75% maximal heart rate) or rest. Using continuous glucose monitors, glucose was measured up to 48 h after the OGTT. Glucose, insulin, and C-peptide were determined at baseline and after 1 and 2 h. One hour after glucose intake, mean blood glucose was significantly lower after cycling compared with rest (p = 0.002). Similarly, mean glucose peak level was significantly lower after cycling compared with after rest (p = 0.039). Lower levels of insulin and C-peptide were observed after 1 h (p < 0.01). Differences in glucose measurements after 2 h and up to 48 h were not statistically different. We found that 20 min of cycling at moderate intensity after glucose intake reduced blood glucose excursions in pregnant women at risk for GDM. ClinicalTrials.gov Identifier: NCT03644238. Novelty Bullets In pregnant women, we found that cycling after glucose intake resulted in significantly lower glucose levels compared with rest. The exercise intervention studied is feasible for pregnant women and could be readily used to reduce glucose excursions.

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.

Dietary sodium, potassium, and blood pressure in normotensive pregnant women: the National Health and Nutrition Examination Survey

Dietary sodium, potassium, and sodium-to-potassium ratio are linearly associated with blood pressure in nonpregnant adults. Earlier investigations suggested null or inverse associations of blood pressure and sodium during normotensive pregnancy; findings have not been confirmed in race/ethnically diverse women or while accounting for potassium. Our purpose was to evaluate associations of blood pressure with sodium and potassium and sodium-to-potassium ratio in race/ethnically diverse normotensive pregnant women. We used cross-sectional blood pressure and dietary data from 984 women in multiple cycles of the National Health and Nutrition Examination Survey (mean age = 27.6 ± 0.2 years). We tested for differences in blood pressure across quartiles of sodium intake using Kruskal-Wallis tests and linear regression to evaluate associations of sodium, potassium, and the sodium-to-potassium ratio with systolic (SBP) and diastolic (DBP) blood pressures. We adjusted for potential confounding variables: age, race/ethnicity, education, marital status, body mass index, smoking, and month of pregnancy. SBP and DBP were similar across quartiles of sodium intake: quartile 1 (lowest sodium intake): 107/59; quartile 2: 106/59; quartile 3: 108/60; quartile 4 (highest sodium intake): 108/58 mm Hg, p > 0.60 for all. Sodium (β = 0.16, 95% confidence interval (CI): -0.20 to 0.52) and potassium (β = 0.18, 95% CI: -0.24 to 0.60) and the sodium-to-potassium ratio (β = -0.54, 95% CI: -1.55 to 0.47) were not associated with SBP or DBP. Results were similar in stratified analyses. Novelty Blood pressure was similar among quartiles of sodium or potassium intake, even in analyses stratified by race/ethnicity and trimester of pregnancy. There was no association of sodium or potassium with blood pressure. Blood pressure may be insensitive to dietary sodium and potassium during normotensive pregnancy.

La présente directive clinique vise à diminuer la probabilité que la pratique de l'excision génitale féminine (EGF) se poursuive et à améliorer les soins prodigués aux filles et aux femmes qui ont subi une EGF ou qui risquent d'en subir une en fournissant (1) des renseignements destinés à améliorer les connaissances et la compréhension de la pratique, (2) des renseignements sur les enjeux juridiques liés à cette pratique, (3) des directives relatives au traitement des complications obstétricales et gynécologiques connexes et (4) des directives sur la compétence culturelle dans la prestation de soins aux filles et femmes touchées par l'EGF.

OPTIONS

Des stratégies de prévention primaire, secondaire et tertiaire de l'EGF et de ses complications. RéSULTATS: Les conséquences à court et à long terme de l'EGF.

UTILISATEURS CIBLES

Les fournisseurs de soins de santé qui fournissent des soins obstétricaux et gynécologiques.

POPULATION CIBLE

Les femmes originaires de pays où l'EGF est couramment pratiquée ainsi que les filles et femmes canadiennes issues de groupes où l'EGF est parfois pratiquée pour des motifs culturels ou religieux. DONNéES PROBANTES: Des recherches ont été effectuées en septembre 2010 dans le moteur PubMed et les bases de données CINAHL et Cochrane Library au moyen d'une terminologie contrôlée appropriée (p. ex. Circumcision, Female) et de mots-clés en anglais (p. ex. female genital mutilation, clitoridectomy, infibulation) afin de rassembler la littérature publiée sur le sujet. Les recherches ont été mises à jour et intégrées à la révision de la directive clinique en décembre 2018. MéTHODES DE VALIDATION: La qualité des données probantes contenues dans le présent document a été évaluée en fonction des critères décrits dans le rapport du Groupe d'étude canadien sur les soins de santé préventifs. AVANTAGES, PRéJUDICES, ET COûTS: Aucun coût ni préjudice n'est anticipé pour la mise en œuvre de cette directive clinique dans les établissements de santé. Au nombre des avantages, la directive pourrait inciter les femmes ayant subi une EGF à solliciter rapidement des soins. DÉCLARATIONS SOMMAIRES: RECOMMANDATIONS.

[Spontaneous triple pregnancy on bicicatricial uterus in the referral health center of commune II of Bamako, Mali]

The trimellar pregnancy on bicicatricial uterus is a rare situation. It can be associated with many maternal-fetal complications. Given these risks, some teams opt for an embryonic reduction. We report a case of spontaneous trimellar pregnancy on bicicatricial uterus. This was a 38 year-old patient, third pregnancy, second birth, 2 alive with a history of 2 caesareans. The evolution of the pregnancy was marked by a urinary tract infection at 34 weeks of gestation. The caesarean section performed at 36 weeks of gestation allowed the birth of 3 newborns, 2 of which were females in 2000 and 1900 grams, and one male weighing 2400 grams. The postpartum was marked by a rapidly resolved eclampsia crisis.
