Determinants of successful labor induction in a teaching hospital in Nigeria: a 10-year review / Determinantes da indução do trabalho de parto bem sucedida em hospital-escola na Nigéria: uma revisão de 10 anos

Abstract Objectives: to evaluate the success rate of labor induction and determinants of successful outcome. Methods: retrospective cohort study of parturients that undergone labor induction between 2006 and 2015. Data was retrieved from the medical records and multivariate logistic regression was used to evaluate the determinants of successful labor induction. Results: the rate of labor induction was 10.9%. Out of the 940 women analysed, six hundred and fifty-six women (69.8%) had successful vaginal delivery. Labor induction at 39-40 weeks (OR=2.70; CI95%=1.17-6.36), 41 weeks (OR=2.44; CI95%=1.14-5.28), estimated fetal weight between 2.5 and 3.4kg (OR=4.27, CI95%=1.96-5.59) and estimated fetal weight of 3.5-3.9kg (OR=5.45; CI95%=2.81-10.60) increased the odds of achieving vaginal delivery. Conclusions: our findings suggest that 39, 40 and 41 weeks are optimal gestational ages for labor induction with respect to successful vaginal delivery. Also, estimated fetal weight between 2.5kg and 3.9kg favours successful vaginal delivery.

Resumo Objetivos: avaliar a taxa de sucesso da indução do trabalho de parto e determinantes de um resultado bem sucedido. Métodos: estudo de coorte retrospectivo de parturientes que submeteram a indução de trabalho de parto entre 2006 e 2015. Os dados foram recuperados dos registros médicos e a regressão logística multivariada foi utilizada para avaliar os determinantes da indução de trabalho de parto bem sucedida. Resultados: a taxa de indução de trabalho de parto foi de 10,9%. Das 940 mulheres analisadas, seiscentas e cinquenta e seis mulheres (69,8%) tiveram um parto vaginal bem sucedido. A indução de trabalho de parto nas 39-40 semanas (OR=2,70; IC95%=1,17-6,36), 41 semanas (OR=2,44; IC95%=1,14-5,28), peso fetal estimado entre 2,5 e 3,4kg OR=4,27; IC95%=1,96-5,59) e peso fetal estimado entre 3,5-3,9kg (OR=5,45; IC95%=2,81-10,60) aumentou as probabilidades de conseguir um parto vaginal. Conclusões: as nossas conclusões sugerem que as 39, 40 e 41 semanas são idades gestacionais ideais para a indução do trabalho de parto no que diz respeito ao sucesso do parto vaginal. Além disso, o peso fetal estimado entre 2,5kg e 3,9kg favorece o parto vaginal bem sucedido.

Obstetric Outcomes in High-Order Repeat Caesarean Deliveries in Nigeria: A Single-Center Retrospective Study.

Objective: Our aim was to evaluate the trend of effect of prior caesarean delivery (CD) on obstetric outcomes; and to investigate the existence of a threshold for order of CD associated with geometrical increase in complications. Materials and methods: We performed a retrospective cohort study of 942 parturients who undergone CD between June 2012 and May 2015 in a teaching hospital in Nigeria. The participants were stratified by the order of caesarean deliveries. We used linear-to-linear association to assess presence of a trend between the order of CD and categorical variables while Jonckheere-Terpstra was used to investigate whether a trend exist between order of CD and continuous variables. We also used multivariate logistic regression to evaluate the relative risk ratio of the outcome variables for each order of CD. Results: Composite adverse maternal outcome depicted a significant increasing trend from 1st CD (5.2%) to the 5thCD (50%). The relative risk ratio for composite adverse maternal outcome increased arithmetically from 1st CD to 3rd CD: RRR2.21, 95%CI 1.2-3.98 for 2ndCD; RRR3.39, 95%CI 1.60-9.27 for 3rdCD; followed by a geometric increase between 3rdCD and 4thCD (RRR11.64, 95%CI 3.20-18.86). In contrast, composite adverse fetal outcome did not depict a significant trend. However, perinatal death increased significantly from primary CD (4.6%) to 5thCD (33.3%). Conclusion: Maternal and fetal complications of repeat CD increase with increasing order of CD; and this trend became astronomical after the third CD. Couples should be counselled that both maternal and fetal complications increase with each additional CD and advised strongly to forgo future pregnancies after the 3rd CD.

Comparison of weight gain between levonorgestrel and etonogestrel implants after 12 months of insertion.

OBJECTIVE: To compare weight gain between women using etonogestrel implants and those using levonorgestrel implants 12 months after insertion. METHODS: A multicenter prospective cohort study was performed on women recruited from family planning clinics between July 2016 and August 2017. The main study outcome was mean weight gain after 12 months of insertion of the implants. RESULTS: The present study included 150 women (age range 18-45 years) using levonorgestrel implants and 167 women using etonogestrel implants. The women recruited had been using implants for less than 6 months; implants had been inserted 6-12 months after their last pregnancy. Participants were followed up until 12 months after insertion through telephone conversations. Baseline parameters were obtained from the clinic records and weight was measured within 6 weeks of the 12-month anniversary of insertion of the implants. Data were analyzed with SPSS version 23. Weight gain in the levonorgestrel group was significantly higher than in the etonogestrel group (3.16 ± 4.08 vs 0.77 ± 3.76, P = 0.013; relative risk 1.69, 95% confidence interval 1.46-1.96). There were no differences in the occurrence of menstrual irregularities and client satisfaction. CONCLUSION: Women using levonorgestrel implants were more likely to gain weight compared to those using etonogestrel implants after 12 months of insertion.

Urinary incontinence: prevalence, pattern, and opportunistic screening in Ile-Ife, Nigeria.

INTRODUCTION AND HYPOTHESIS: Urinary incontinence is a source of health-related poor quality of life. It is, however, rarely disclosed, except when specifically enquired about by the healthcare provider. This study determined the prevalence of urinary incontinence and opportunistic screening for it in women attending a general outpatient clinic. METHODS: A total of 1,250 consenting women attending a general outpatient clinic in Ile-Ife, a semi-urban town in Southwest Nigeria, were recruited into this cross-sectional study. Confidential post-consultation interviews were performed in each patient to determine whether they had been asked about urinary incontinence and whether they felt that they ought to have been asked. The Questionnaire for Urinary Incontinence Diagnosis (QUID) was administered to determine the prevalence and pattern of urinary incontinence. Results were expressed as proportions and compared using the Chi-squared test. RESULTS: The subjects' ages ranged from 20 to 100 years (mean = 46.8 ± 17.7 years). Sixty-five women had urinary incontinence (prevalence = 5.2 %). QUID classified 30 (2.4 %), 23 (1.8 %), and 12 (1.0 %) of them as having urge, stress, and mixed incontinence respectively. None of them self-reported incontinence to their physicians. Only 9 incontinent (13.8 %) and 44 continent women (3.7 %) had opportunistic screening (p < 0.001). Fifty of the incontinent women (76.9 %) felt that their physician ought to have asked them about it. Forty-eight of them (73.8 %) did not consider incontinence a sufficient reason for presentation in hospital, but the majority (90.7 %) desired treatment. CONCLUSION: Urinary incontinence was occasionally present, but usually undisclosed by women attending the general outpatient clinic, unless when specifically asked by their physicians. Opportunistic screening is therefore recommended in this setting.
