RESUMEN
OBJECTIVES: To update the Ghana PrenaBelt Trial's (GPT) primary outcome data with the latest fetal growth standard and reanalyse it. To estimate the posterior probability, under various clinically relevant prior probabilities, of maternal nightly positional therapy (PT) throughout the third-trimester having a beneficial effect on customised birth weight centile (CBWC) using Bayesian analyses. DESIGN: A reanalysis of a double-blind, sham-controlled, randomised clinical trial. SETTING: A single, tertiary-level centre in Accra, Ghana. PARTICIPANTS: Two-hundred participants entered, 181 completed and 167 were included in the final analysis. Participants were Ghanaian, healthy, aged 18-35 years, with low-risk, singleton pregnancies in their third-trimester, 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: Participants were randomised to receive treatment with either a PT or sham-PT device. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the CBWC using the latest Perinatal Institute, Gestation-Related Optimal Weight calculator. Using Bayesian methods, posterior probabilities of achieving a greater than 0%, 5% and 10% benefit in CBWC with PT were estimated. There was no secondary outcome. RESULTS: The median (IQR) CBWC was 42% (15-71) and 28% (9-52) in the PT and sham-PT groups, respectively (difference 8.4%; 95% CI -0.30 to 18.2; p=0.06). For achieving a >0%, >5% and >10% gain in CBWC with PT, the posterior probabilities were highly probable, probable and unlikely, respectively, given a range of prior probabilities reflecting varying degrees of pre-existing enthusiasm and scepticism. CONCLUSIONS: Maternal nightly PT throughout the third-trimester did not have a statistically significant effect on CBWC on a frequentist analysis using the latest fetal growth standard. However, from a Bayesian analysis, clinicians can infer that PT is likely to benefit fetal growth but with a modest effect size. TRIAL REGISTRATION NUMBER: NCT02379728.

Wilms tumor (WT) occurring in adults is rare and even much more rarely found to coexist with pregnancy. Clinical outcome in adults is worse overall compared with pediatric patients with WT and is often misdiagnosed with no standardized protocols for care guided by high-evidence clinical trials. We present a case of a 23-year-old woman diagnosed with WT who was found to be pregnant immediately following nephrectomy. Workup findings showed that she had disseminated disease but was successfully managed in a multidisciplinary team setting with modified intrapartum chemotherapy followed by postpartum chemotherapy. In low-resource settings, management protocols for adult patients with WT can be individualized by multidisciplinary teams to leverage available resources for best outcomes.

Acute uterine inversion is a rare and potentially life-threatening obstetric emergency. Its occurrence as a result of a mid-trimester abortion is an even rarer consequence. We report a case of a 32-year-old woman who presented with complete acute uterine inversion and hemorrhagic shock following an incomplete medical abortion at 14 weeks of gestation. Our attempts at non-operative reversal of the inversion failed. Therefore, we resorted to the manual replacement of the uterus via laparotomy without using surgical instruments or an incision in the cervical ring. The laparotomic manual replacement served as a successful alternative with minimal immediate or long-term morbidity that may have resulted from trauma and scarring of the uterus.

BACKGROUND: Women of African ancestry are highly predisposed to preeclampsia which continues to be a major cause of maternal death in Africa. Common variants in the APOL1 gene are potent risk factor for a spectrum of kidney disease. Recent studies have shown that APOL1 risk variants contribute to the risk of preeclampsia. The aim of the study is to understand the contribution of APOL1 risk variants to the development of preeclampsia in pregnant women in Ghana. METHODS: The study is a case-control design which started recruitment in 2019 at the Korle Bu Teaching Hospital in Ghana. The study will recruit pregnant women with a target recruitment of 700 cases of preeclampsia and 700 normotensives. Clinical and demographic data of mother- baby dyad, with biospecimens including cord blood and placenta will be collected to assess clinical, biochemical and genetic markers of preeclampsia. The study protocol was approved by Korle Bu Teaching Hospital Institutional Review Board (Reference number: KBTH-IRB/000108/2018) on October 11, 2018. PRELIMINARY RESULTS: As of December 2021, a total of 773 mother-baby pairs had been recruited and majority of them had complete entry of data for analysis. The participants are made up of 384 preeclampsia cases and 389 normotensive mother-baby dyad. The mean age of participants is 30.69 ± 0.32 years for cases and 29.95 ± 0.32 for controls. Majority (85%) of the participants are between 20-30years. At booking, majority of cases had normal blood pressure compared to the time of diagnosis where 85% had a systolic BP greater than 140mmHg and a corresponding 82% had diastolic pressure greater than 90mmHg. CONCLUSION: Our study will ultimately provide clinical, biochemical and genotypic data for risk stratification of preeclampsia and careful monitoring during pregnancy to improve clinical management and outcomes.

A retained drainage tube after surgery is rare and patients may be asymptomatic if it occurs. The presence of a retained drainage tube may be first recognized on imaging and this requires a high index of suspicion by radiologists. In this case report, we described an incidental finding of an asymptomatic retained fractured drainage tube in the pelvis of a 32-year-old female on ultrasonography for renal evaluation. This highlighted the need for radiologists to have a high index of suspicion when performing ultrasonography on postoperative patients and surgeons should be meticulous when removing drainage tubes postsurgery. The possibility of a foreign body should be considered when unfamiliar findings are encountered on imaging. Surgeons should inspect drainage tubes after removal to ensure the full length of the tube is removed.
RESUMEN
Objectives: Clozapine-induced myocarditis may be a hypersensitivity reaction due to titration that was too rapid for a patient's clozapine metabolism. Obesity, infections, and inhibitors (e.g., valproate) may lead to clozapine poor metabolizer (PM) status. The hypothesis that 4 patients with clozapine-induced myocarditis from two United States hospitals were clozapine PMs was tested by studying their minimum therapeutic clozapine doses and titrations. Methods: Using methodology from a prior myocarditis case series of 9 Turkish patients, we studied: 1) the concentration-to-dose (C/D) ratio; 2) minimum therapeutic dose required to reach 350 ng/ml (a marker for PM status); and 3) titration speed. Results: All 4 patients were possible clozapine PMs (their respective minimum therapeutic doses were: 134, 84, 119 and 107 mg/day). The identified possible contributors to clozapine PM status were: 1) valproate in Cases 1, 2 and 4; 2) obesity and a urinary tract infection in Case 2; and 3) obesity and very rapid titration in Case 4. Case 3, who was given a normal US titration, appeared to be a genetic clozapine PM. He developed clozapineinduced drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome after rechallenge using 12.5 mg/day > 3 months later. The results were similar to 9 Turkish cases, all of which were PMs (6 on valproate, 4 with obesity, 1 with infection and 1 possibly genetic). Conclusions: Future studies using clozapine levels and considering the role of clozapine PM status should explore whether or not all cases of clozapine-induced myocarditis could be explained by lack of individualized titration.

The co-existence of pheochromocytoma and pregnancy is rare, with poor maternal and foetal outcomes. This is a case report of a young Ghanaian woman with a pre-existing diagnosis of recurrent pheochromocytoma who became pregnant and experienced elevated blood pressure in the third trimester with proteinuria and abnormal liver function. She was managed as an in-patient and delivered a live baby via caesarean section at 34 weeks after detecting intra-uterine growth restriction. Management of such cases by a multidisciplinary team is recommended for optimal outcomes.

We conducted a pre/post study of a post-partum hemorrhage (PPH) simulation exercise at Korle Bu Hospital, using a low-fidelity birthing simulator and questionnaires. We aimed to evaluate low-fidelity simulation as a feasible and effective method of improving resident knowledge and confidence in a low-resource setting. Knowledge and confidence in PPH management were measured before and after using 5-point Likert scales and multiple-choice questions. A feedback survey was administered. Descriptive statistics were calculated to summarize demographics, confidence, and knowledge, with frequencies, means and standard deviations reported. Statistical significance of the change in scores was assessed using paired t tests. Statistically significant improvements in knowledge and confidence in managing PPH were evident following the simulation exercise. All participants agreed the simulation was educational, relevant and realistic, and 94% felt it could be incorporated into their training.

OBJECTIVE: To evaluate the effect, on birth weight and birth weight centile, of use of the PrenaBelt, a maternal positional therapy device, during sleep in the home setting throughout the third trimester of pregnancy. DESIGN: A double-blind, sham-controlled, randomised clinical trial. SETTING: Conducted from September 2015 to May 2016, at a single, tertiary-level centre in Accra, Ghana. PARTICIPANTS: Two-hundred participants entered the study. One-hundred-eighty-one participants completed the study. Participants were women, 18 to 35 years of age, with low-risk, singleton, pregnancies in their third-trimester, with body mass index <35 kg/m2 at the first antenatal appointment for the index pregnancy and without known foetal abnormalities, pregnancy complications or medical conditions complicating sleep. INTERVENTIONS: Participants were randomised by computer-generated, one-to-one, simple randomisation to receive either the PrenaBelt or sham-PrenaBelt. Participants were instructed to wear their assigned device to sleep every night for the remainder of their pregnancy (approximately 12 weeks in total) and were provided a sleep diary to track their use. Allocation concealment was by unmarked, security-tinted, sealed envelopes. Participants and the outcomes assessor were blinded to allocation. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcomes were birth weight and birth weight centile. Secondary outcomes included adherence to using the assigned device nightly, sleeping position, pregnancy outcomes and feedback from participants and maternity personnel. RESULTS: One-hundred-sixty-seven participants were included in the primary analysis. The adherence to using the assigned device nightly was 56%. The mean ±SD birth weight in the PrenaBelt group (n=83) was 3191g±483 and in the sham-PrenaBelt group (n=84) was 3081g±484 (difference 110 g, 95% CI -38 to 258, p=0.14). The median (IQR) customised birth weight centile in the PrenaBelt group was 43% (18 to 67) and in the sham-PrenaBelt group was 31% (14 to 58) (difference 7%, 95% CI -2 to 17, p=0.11). CONCLUSIONS: The PrenaBelt did not have a statistically significant effect on birth weight or birth weight centile in comparison to the sham-PrenaBelt. TRIAL REGISTRATION NUMBER: NCT02379728.

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. TRIAL REGISTRATION NUMBER: NCT02377817; Results.

INTRODUCTION: The cardio-thoracic ratio (CTR) and the transverse cardiac diameter (TCD) on Plain chest radiography are the two parameters commonly used to diagnose cardiomegaly and heart disease. A CTR of greater than 50% on a PA film is abnormal and normally indicates cardiac or pericardial disease condition, whiles an increase of TCD from 1.5 to 2cm on two consecutive radiographs, taken at short interval, suggests possible cardiac pathology. The aim was to determine the suitability of using the same TCD and CTR to detect cardiomegaly for all age groups and genders respectively. METHODS: A retrospective study involved the review of 1047 radiological images of adults aged 21 to 80 years, who had plain postero-anterior chest radiographs between January 2012 and November 2013 by 3 radiologists. Data recorded included the transverse cardiac, thoracic diameter and the cardiothoracic ratios. Descriptive analyses were carried out using the Microsoft excel 2010. RESULTS: The mean age and standard deviation for the study population was 35.1 ± 12.7. The mean and standard deviations for the transverse cardiac diameter, thoracic diameter, and the cardiothoracic ratios for male participants were 13.08cm ± 1.2, 29.7cm ± 2.7 and 46.6% ± 3.9; and 12.9 cm ± 1.3, 27.1 cm ± 2.6, and 47.8% ± 4.8 for females. An increase in TCD of 1cm resulted in a CTR of greater than 50.0% in all but the males aged 21-40 years. CONCLUSION: The study found that the same TCD and CTR values are not suitable in detecting cardiomegaly for all age groups and genders.

Uterine fibroids in pregnancy present with numerous complications. However, spontaneous rupture is a rare and potentially life-threatening event. We report a case of a 43-year-old multiparous woman who presented with hypovolemic shock secondary to a ruptured uterine fibroid 2 days after a spontaneous vaginal delivery. Emergency laparotomy confirmed massive intra-abdominal hemorrhage from the ruptured capsule of a 10-cm subserosal fibroid. A myomectomy was performed. Her postoperative recovery period was uneventful. This case is very rare, with fewer than 30 cases of hemoperitoneum secondary to rupture of fibroids having been reported in published works. It demonstrates how a benign and common condition, such as fibroids, can lead to an obstetric emergency that mimics a surgical abdomen requiring swift diagnosis and surgical intervention.

OBJECTIVE: To study maternal and fetal outcomes in Ghanaian women with systemic lupus erythematosus (SLE). METHODS: Retrospective study of pregnancies in women with SLE in a single centre in Ghana. RESULTS: The mean age was 30.1 years and all were nulliparous. Two out of the seven pregnancies were in disease remission at the time of booking. Nephritis without renal impairment was present in 7 pregnancies (6 women). One woman developed intrapartum eclampsia. Two women had secondary antiphospholipid syndrome (APS). Two suffered early fetal losses and one late fetal loss at 32 weeks. All three who lost their fetus had uncontrolled hypertension. Six had mild flares mainly joint pains during pregnancy. There was no maternal mortality. The median gestational age at delivery was 38 weeks (range, 16 to 40 weeks) and the mean birth weight was 3017 g; the median Apgar scores were 8 and 9 at 1 and 5 minutes of life, respectively. There were no cases of intrauterine growth restriction (IUGR). There were no cases of congenital heart block or neonatal lupus. CONCLUSION: Good pregnancy outcomes are possible in women with SLE even in resource poor settings. . All pregnancies should still be considered high risk and be managed jointly between the obstetricians, the perinatologists and the rheumatologists, in particular, those with renal involvement and hypertension. Long term follow up of a larger cohort is needed. FUNDING: None declared.

The study provided baseline data of abruptio placentae in Korle-Bu Teaching Hospital (KBTH), Ghana, and gave recommendations to minimize poor outcomes. A prospective cross sectional study was conducted at the Maternity Department of the KBTH between February 2008 and January 2010. Two hundred women with diagnosis of placental abruption were studied using a pretested standardized structured questionnaire. Statistical Package for Social Sciences (SPSS) version 17 was used to analyse the data. Fifteen thousand five hundred and ten (15,510) deliveries were recorded during the study period out of which 1.4% abruptio placentae cases were confirmed. The perinatal and maternal mortality rates were 65% and 2% respectively. The key risk factors identified were low socio-economic status, grandmultiparity and hypertensive disorders in pregnancy. Intrauterine foetal death, (IUFD) and maternal shock were significantly associated with coagulopathy (p=0.001 and 0.004 respectively). Early diagnoses of placental abruption will significantly improve foetal and maternal survival.

OBJECTIVE: To assess sleep practices, and investigate their relationship with maternal and fetal outcomes, among pregnant Ghanaian women. METHODS: In a cross-sectional study conducted at Korle Bu Teaching Hospital, Accra, Ghana, between June and July 2011, postpartum women were interviewed within 48hours of delivery about sleep quality and practices during pregnancy. Interviews were coupled with a systematic review of participants' medical charts for key outcomes including maternal hypertension, pre-eclampsia, premature delivery, low birth weight, and stillbirth. RESULTS: Most women reported poor sleep quality during pregnancy. Snoring during pregnancy was independently associated with pre-eclampsia (odds ratio [OR], 3.5; 95% confidence interval [CI], 1.4-8.5; P=0.007). The newborns of women who reported supine sleep during pregnancy were at increased risk of low birth weight (OR, 5.0; 95% CI, 1.2-20.2; P=0.025) and stillbirth (OR, 8.0; 95% CI, 1.5-43.2; P=0.016). Low birth weight was found to mediate the relationship between supine sleep and stillbirth. CONCLUSION: The present findings in an African population demonstrate that maternal sleep, a modifiable risk factor, has a significant role in pre-eclampsia, low birth weight, and subsequently stillbirth.

In order to evaluate the efficacy of constructed wetlands for treatment of domestic wastewater for small communities located in rural areas, small-scale wetland mesocosms (400 L each) containing two treatment designs (a mixture of Typha, Scirpus, and Juncus species; control without vegetation) were planted into two depths (45 or 60 cm) with pea gravel. Each mesocosm received 19 L/day of primary-treated domestic sewage. Mesocosms were monitored (inflow and outflow samples) on a monthly basis over a 2-year period for pH, total suspended solids (TSS), 5-day biochemical oxygen demand (BOD(5)), total Kjeldahl nitrogen (TKN), dissolved oxygen (DO), and conductivity. Microbiological analyses included enumeration of fecal coliforms, enterococci, Salmonella, Shigella, Yersinia, and coliphage. Significant differences between influent and effluent water quality for the vegetated wetlands (p<0.05) were observed in TSS, BOD(5), and TKN. Increased DO and reduction in fecal coliform, enterococcus, Salmonella, Shigella, Yersinia, and coliphage populations also were observed in vegetated wetlands. Greatest microbial reductions were observed in the planted mesocosms compared to those lacking vegetation. Despite marked reduction of several contaminants, wetland-treated effluents did not consistently meet final discharge limits for receiving bodies of water. Removal efficiencies for bacteria and several chemical parameters were more apparent during the initial year compared to the second year of operation, suggesting concern for long-term efficiency and stability of such wetlands.
