Mise à jour thérapeutique et pronostique de la rupture utérine dans une maternité à Bangui, CAR

BACKGROUND

Maternal mortality rates remain high (882/100,000 births) in the Central African Republic (CAR), primarily due to frequent obstetric complications. Médecins Sans Frontières supports a referral maternity ward in the capital, Bangui.

OBJECTIVES

To describe the prevalence, associated factors and fatality of one of the most severe complications, uterine rupture, as well as the effect of a history of uterine surgery.

METHODS

This is a cross-sectional study based on retrospectively collected data between January 2018 and December 2021 for women who delivered new-borns weighing over 1,000 g.

RESULTS

Of 38,782 deliveries, 229 (0.6%) cases of uterine rupture were recorded. Factors associated with uterine rupture were parity ⩾5 (adjusted odds ratio [aOR] 7.5, 95% confidence interval [CI] 4.6-12.2), non-occipital foetal presentation (aOR 2.8, 95% CI 2.1-3.7) and macrosomia (OR 4, 95% CI 2.6-6.4). The fatality rate was 4.4%, and the stillbirth rate was 64%. Uterine rupture occurred in non-scarred uterus in 150 (66.1%) women. Adverse outcomes were more common in cases of uterine rupture on non-scarred uterus compared to scarred uterus, with higher maternal mortality (6% vs. 0%, P = 0.023) and lower Apgar scores (<2) for new-borns (69.1% vs. 45.8%, P < 0.001).

CONCLUSION

Uterine rupture remains a major issue for maternal and perinatal health in the CAR, and efforts are needed to early detect risk factors and increase coverage of the comprehensive emergency obstetric and neonatal care.

High severity of abortion complications in fragile and conflict-affected settings: a cross-sectional study in two referral hospitals in sub-Saharan Africa (AMoCo study)

BACKGROUND

Abortion-related complications are one of the five main causes of maternal mortality. However, research about abortion is very limited in fragile and conflict-affected settings. Our study aims to describe the magnitude and severity of abortion-related complications in two referral hospitals supported by Médecins Sans Frontières and located in such settings in northern Nigeria and Central African Republic (CAR).

METHODS

We used a methodology similar to the World Health Organization (WHO) near-miss approach adapted in the WHO multi-country study on abortion (WHO-MCS-A). We conducted a cross-sectional study in the two hospitals providing comprehensive emergency obstetric care. We used prospective medical records' reviews of women presenting with abortion-related complications between November 2019 and July 2021. We used descriptive analysis and categorized complications into four mutually exclusive categories of increasing severity.

RESULTS

We analyzed data from 520 and 548 women respectively in Nigerian and CAR hospitals. Abortion complications represented 4.2% (Nigerian hospital) and 19.9% (CAR hospital) of all pregnancy-related admissions. The severity of abortion complications was high: 103 (19.8%) and 34 (6.2%) women were classified as having severe maternal outcomes (near-miss cases and deaths), 245 (47.1%) and 244 (44.5%) potentially life-threatening, 39 (7.5%) and 93 (17.0%) moderate, and 133 (25.6%) and 177 (32.3%) mild complications, respectively in Nigerian and CAR hospitals. Severe bleeding/hemorrhage was the main type of complication in both settings (71.9% in the Nigerian hospital, 57.8% in the CAR hospital), followed by infection (18.7% in the Nigerian hospital, 27.0% in the CAR hospital). Among the 146 women (Nigerian hospital) and 231 women (CAR hospital) who did not report severe bleeding or hemorrhage before or during admission, anemia was more frequent in the Nigerian hospital (66.7%) compared to the CAR hospital (37.6%).

CONCLUSION

Our data suggests high severity of abortion-related complications in these two referral facilities of fragile and conflict-affected settings. Factors that could contribute to this high severity in these contexts include greater delays in accessing post-abortion care, decreased access to contraceptive and safe abortion care that result in increased unsafe abortions; as well as increased food insecurity leading to iron-deficiencies and chronic anaemia. The results highlight the need for better access to safe abortion care, contraception, and high quality postabortion care to prevent and manage complications of abortion in fragile and conflict-affected settings.

Provision of emergency obstetric care at secondary level in a conflict setting in a rural area of Afghanistan - is the hospital fulfilling its role?

Background

Provision of Emergency Obstetric and Neonatal Care (EmONC) reduces maternal mortality and should include three components: Basic Emergency Obstetric and Neonatal Care (BEmONC) offered at primary care level, Comprehensive EmONC (CEmONC) at secondary level and a good referral system in-between. In a conflict-affected province of Afghanistan (Khost), we assessed the performance of an Médecins Sans Frontières (MSF) run CEmONC hospital without a primary care and referral system. Performance was assessed in terms of hospital utilisation for obstetric emergencies and quality of obstetric care.

Methods

A cross-sectional study using routine programme data (2013–2014).

Results

Of 29,876 admissions, 99% were self-referred, 0.4% referred by traditional birth attendants and 0.3% by health facilities. Geographic origins involved clustering around the hospital vicinity and the provincial road axis. While there was a steady increase in hospital caseload, the number and proportion of women with Direct Obstetric Complications (DOC) progressively dropped from 21% to 8% over 2 years. Admissions for normal deliveries continuously increased. In-hospital maternal deaths were 0.03%, neonatal deaths 1% and DOC case-fatality rate 0.2% (all within acceptable limits).

Conclusions

Despite a high and ever increasing caseload, good quality Comprehensive EmONC could be offered in a conflict-affected setting in rural Afghanistan. However, the primary emergency role of the hospital is challenged by diversion of resources to normal deliveries that should happen at primary level. Strengthening Basic EmONC facilities and establishing an efficient referral system are essential to improve access for emergency cases and increase the potential impact on maternal mortality.

Dilemmas in Managing Pregnant Women With Ebola: 2 Case Reports

We report 2 cases of Ebola viral disease (EVD) in pregnant women who survived, initially with intact pregnancies. Respectively 31–32 days after negativation of the maternal blood EVD-polymerase chain reaction (PCR) both patients delivered a stillborn fetus with persistent EVD-PCR amniotic fluid positivity.

Porosity measurements of sedimentary rocks by means of microfocus X-ray computed tomography (μCT)

Porosity of reservoir rocks is an important petrophysical characteristic, used as a basic parameter in simulation studies for predicting reservoir quality. An extensive debate continues about the techniques that are available for porosity measurements and visualization. One aspect is the fact that petrophysical measurements are performed on volumetric samples, whereas classical geological petrography using a petrographical microscope is restricted to 2D analysis. This leads to a discrepancy between petrographical and petrophysical studies. This paper aims to evaluate microfocus X-ray computed tomography (μCT) as a technique that can link petrography and petrophysics. A short overview of the μCT technique is given, together with a discussion of its limitations, mainly due to artefacts. Optimization of image quality and procedures for quantification are outlined. μCT results for porosity measurements of a limestone and a sandstone are compared with results obtained by other techniques.
