RESUMEN

BACKGROUND: High-risk pregnancies, such as twin pregnancies, deserve particular attention as mortality is very high in this group. With a view to inform policy and national guidelines development for the Sustainable Development Goals, we reviewed national training materials, guidelines, and policies underpinning the provision of care in relation to twin pregnancies and assessed care provided to twins in 8 Eastern and Southern African countries: Kenya, Malawi, Mozambique, Rwanda, Tanzania, Uganda, Zambia, and Zimbabwe. METHODS AND FINDINGS: We located policies and guidelines by reviewing national repositories and by contacting experts to systematically map country-level maternal and newborn training materials, guidelines, and policies. We extracted recommendations for care for twins spanning ante-, intra-, and postpartum care that typically should be offered during twin pregnancies and childbirth. We compared care provided for mothers of twins to that provided for mothers of singletons during the ante-, intra-, and postpartum period and computed neonatal mortality rates using the most recent Demographic and Health Surveys (DHS) data for each country. There was a paucity of guidance on care specifically for twin or multiple pregnancies: None of the countries provided clear guidance on additional number of antenatal care visits or specific antenatal content, while 7 of the 8 countries recommended twins to be delivered in a comprehensive emergency obstetric and neonatal care facility. These results were mirrored by DHS results of 73,462 live births (of which 1,360 were twin) indicating that twin pregnancies did not receive more frequent or intensified antenatal care. The percentage of twin deliveries in hospitals varied from 25.3% in Mozambique to 63.0% in Kenya, and women with twin deliveries were between 5 and 27 percentage points more likely to deliver in hospitals compared to women with singleton live births; this difference was significant in 5 of the 8 countries (t test p < 0.05). The percentage of twin deliveries by cesarean section varied from 9% in Mozambique to 36% in Rwanda. The newborn mortality rate among twins, adjusted for maternal age and parity, was 4.6 to 7.2 times higher for twins compared to singletons in all 8 countries. CONCLUSIONS: Despite the limited sample size and the limited number of clinically relevant services evaluated, our study provided evidence that mothers of twins receive insufficient care and that mortality in twin newborns is very high in Eastern and Southern Africa. Most countries have insufficient guidelines for the care of twins. While our data do not allow us to make a causal link between insufficient guidelines and insufficient care, they call for an assessment and reconceptualisation of policies to reduce the unacceptably high mortality in twins in Eastern and Southern Africa.

RESUMEN

OBJECTIVE: We endeavored to create a comprehensive course in global surgery involving multinational exchange. DESIGN: The course involved 2 weeks of didactics, 2 weeks of clinical rotations in a low-resource setting and 1 week for a capstone project. We evaluated our success through knowledge tests, surveys of the students, and surveys of our Zimbabwean hosts. SETTING: The didactic portions were held in Sweden, and the clinical portion was primarily in Harare with hospitals affiliated with the University of Zimbabwe. PARTICIPANTS: Final year medical students from Lund University in Sweden, Harvard Medical School in the USA and the University of Zimbabwe all participated in didactics in Sweden. The Swedish and American students then traveled to Zimbabwe for clinical work. The Zimbabwean students remained in Sweden for a clinical experience. RESULTS: The course has been taught for 3 consecutive years and is an established part of the curriculum at Lund University, with regular participation from Harvard Medical School and the University of Zimbabwe. Participants report significant improvements in their physical exam skills and their appreciation of the needs of underserved populations, as well as confidence with global surgical concepts. Our Zimbabwean hosts thought the visitors integrated well into the clinical teams, added value to their own students' experience and believe that the exchange should continue despite the burden associated with hosting visiting students. CONCLUSIONS: Here we detail the development of a course in global surgery for medical students that integrates didactic as well as clinical experiences in a low-resource setting. The course includes a true multilateral exchange with students from Sweden, the United States and Zimbabwe participating regularly. We hope that this course might serve as a model for other medical schools looking to establish courses in this burgeoning field.

RESUMEN

OBJECTIVES: Haemorrhage, hypertension, sepsis and abortion complications (often from haemorrhage or sepsis) contribute to 60% of all maternal deaths. Each is associated with vital signs (blood pressure (BP) and pulse) abnormalities, and the majority of deaths are preventable through simple and timely intervention. This paper presents the development and evaluation of the CRADLE Vital Signs Alert (VSA), an accurate, low-cost and easy-to-use device measuring BP and pulse with an integrated traffic light early warning system. The VSA was designed to be used by all cadres of healthcare providers for pregnant women in low-resource settings with the aim to prevent avoidable maternal mortality and morbidity. METHODS: The development and the mixed-methods clinical evaluation of the VSA are described. RESULTS: Preliminary fieldwork identified that introduction of BP devices to rural clinics improved antenatal surveillance of BP in pregnant women. The aesthetics of the integrated traffic light system were developed through iterative qualitative evaluation. The traffic lights trigger according to evidence-based vital sign thresholds in hypertension and haemodynamic compromise from haemorrhage and sepsis. The VSA can be reliably used as an auscultatory device, as well as its primary semiautomated function, and is suitable as a self-monitor used by pregnant women. CONCLUSION: The VSA is an accurate device incorporating an evidence-based traffic light early warning system. It is designed to ensure suitability for healthcare providers with limited training and may improve care for women in pregnancy, childbirth and in the postnatal period.

RESUMEN

BACKGROUND: Obstetric haemorrhage, sepsis and pregnancy hypertension account for more than 50% of maternal deaths worldwide. Early detection and effective management of these conditions relies on vital signs. The Microlife® CRADLE Vital Sign Alert (VSA) is an easy-to-use, accurate device that measures blood pressure and pulse. It incorporates a traffic-light early warning system that alerts all levels of healthcare provider to the need for escalation of care in women with obstetric haemorrhage, sepsis or pregnancy hypertension, thereby aiding early recognition of haemodynamic instability and preventing maternal mortality and morbidity. The aim of the trial was to determine whether implementation of the CRADLE intervention (the Microlife® CRADLE VSA device and CRADLE training package) into routine maternity care in place of existing equipment will reduce a composite outcome of maternal mortality and morbidity in low- and middle-income country populations. METHODS: The CRADLE-3 trial was a stepped-wedge cluster-randomised controlled trial of the CRADLE intervention compared to routine maternity care. Each cluster crossed from routine maternity care to the intervention at 2-monthly intervals over the course of 20 months (April 2016 to November 2017). All women identified as pregnant or within 6 weeks postpartum, presenting for maternity care in cluster catchment areas were eligible to participate. Primary outcome data (composite of maternal death, eclampsia and emergency hysterectomy per 10,000 deliveries) were collected at 10 clusters (Gokak, Belgaum, India; Harare, Zimbabwe; Ndola, Zambia; Lusaka, Zambia; Free Town, Sierra Leone; Mbale, Uganda; Kampala, Uganda; Cap Haitien, Haiti; South West, Malawi; Addis Ababa, Ethiopia). This trial was informed by the Medical Research Council guidance for complex interventions. A process evaluation was undertaken to evaluate implementation in each site and a cost-effectiveness evaluation will be undertaken. DISCUSSION: All aspects of this protocol have been evaluated in a feasibility study, with subsequent optimisation of the intervention. This trial will demonstrate the potential impact of the CRADLE intervention on reducing maternal mortality and morbidity in low-resource settings. It is anticipated that the relatively low cost of the intervention and ease of integration into existing health systems will be of significant interest to local, national and international health policy-makers. TRIAL REGISTRATION: ISCRTN41244132. Registered on 2 February 2016. Prospective protocol modifications have been recorded and were communicated to the Ethics Committees and Trials Committees.

RESUMEN

Guillain-Barré syndrome is a rare condition in pregnancy which is characterised by symmetrical progressive ascending polyneuropathy. A case of a 16-year-old nulliparous woman who presented with rapidly progressive limb paralysis following an upper respiratory tract infection a week prior to presentation is discussed. She was intubated as she had developed respiratory failure and managed in the intensive care unit by a multidisciplinary team. Plasma exchange and intravenous immunoglobulin were not readily available so she was managed conservatively. The management of Guillain-Barré syndrome, maternal and foetal outcomes have been discussed.

RESUMEN

BACKGROUND: Metastatic vulval adenocarcinoma is a rare occurrence with only a few cases reported to date. They can arise from the breast, gastrointestinal system, or endometrium. CASE PRESENTATION: We present the case of a 55-year-old Black African woman who presented with vulval itching which progressed to warty lesions. Histology revealed a vulval adenocarcinoma which immunohistochemistry suggested was of gastrointestinal origin. Colonoscopy later confirmed an anorectal tumor as the primary site. Despite extensive chest metastases she looked surprisingly well and had no pulmonary symptoms. The major source of symptomatic distress was the itchy extensive warty lesions on her vulva. She has since had a vulvectomy which gave her significant symptomatic relief. CONCLUSIONS: This case was interesting as vulval adenocarcinoma is a rare histological diagnosis found in less than 10% of vulval cancers. Primary vulval adenocarcinoma is rare with most of these cancers being secondary metastases from a distant site. Her symptoms were predominantly vulval with no chest symptoms even though she had extensive pulmonary metastases. She has been clinically well except for the itching suggesting an indolent course.

RESUMEN

We report three cases illustrating difficulties in diagnosis and challenges with management of the placenta in a low-resource country where ultrasound scanning, methotrexate, interventional radiology or blood products are often not accessible for the majority of patients. Even in situations where an ultrasound scan is available prenatally as in our three cases, the diagnosis is often missed. All the cases presented with vague abdominal symptoms, which are common in pregnancy anyway. Only one case was correctly diagnosed before surgery by ultrasound scan. For the two cases in the second trimester as expected the fetuses did not survive. The one advanced pregnancy had a good perinatal outcome. Maternal morbidity and mortality usually results from perioperative hemorrhage from the placental attachment site. The most important aspect of management is the management of the placenta. In the two cases with second trimester pregnancies, it was possible to remove the placentas, even though blood loss was significant, hemostasis was achieved at surgery. All three mothers recovered well and survived.
