Accuracy of portable ultrasound for obstetric biometry.

OBJECTIVE: We assessed the accuracy of two portable ultrasound machines (PUM) in obtaining fetal biometry and estimating gestational age. METHODS: We analyzed data from the Fetal Age Machine Learning Initiative, an observational study of pregnant women in the United States and Zambia. Each participant underwent assessment by an experienced sonographer using both a high-specification ultrasound machine (HSUM) and a PUM (either Butterfly iQ or Clarius C3) to measure fetal biometry and calculate estimated gestational age (EGA) at each visit. Through comparison of paired PUM-HSUM scans, we estimated agreement between individual biometry measurements and aggregate gestational age estimates by reporting mean difference, along with intraclass correlation coefficient (ICC) and Bland-Altman plots, adjusting for trend. RESULTS: 881 participants contributed 1386 paired PUM-HSUM ultrasound studies between April and December 2021. PUM studies included 991 Butterfly and 395 Clarius. Gestational age at scan ranged from 7 to 38 weeks. Compared to HSUM, the Butterfly PUM had a mean difference of -0.20 days (95%CI±0.40) in the 1st trimester and -0.68 days (95%CI±0.68) in the 2nd/3rd trimesters. Also compared to HSUM, the Clarius PUM had a mean difference of 0.47 days (95%CI±0.64) in the 1st trimester and -1.67 days (95%CI±0.43) in the 2nd/3rd trimesters. ICCs were 0.989 or greater throughout. Increasing gestational age was associated with increasing error and absolute error. Both PUM devices demonstrated a modest trend toward underestimation of EGA at advancing gestational ages in 2nd/3rd trimester scans, compared to HSUM. CONCLUSION: Both the Butterfly iQ and Clarius C3 PUM devices were highly accurate in performing fetal biometry in a diverse population from the US and Zambia. This article is protected by copyright.

Barriers to implementation of placental transfusion of babies at birth in Zambia.

Delayed cord clamping (DCC) and umbilical cord milking (CM) have many benefits. However, a previous study done in Zambia showed that it was not a common practice among midwives. This study investigated possible barriers to DCC and CM, at the University Teaching Hospital in Lusaka. This was a qualitative study. A convenience sample was chosen, and snowball sampling was used. The midwives were interviewed using semi-structured interviews. Burnard's method of thematic content analysis was used. Through 14 interviews it became clear that the midwives were aware of DCC and used it whenever possible. The participants reported that the main barriers were the high workload and a variation in knowledge. A lack of facilities, such as heaters and resuscitation equipment in the delivery room also led to earlier cord clamping. The midwives were motivated to continue improving the routines. They expressed a need for more training as well as equipment and resources to facilitate DCC.

Association of socioeconomic status with adverse birth outcomes at the Women and Newborn Hospital of the University Teaching Hospitals in Lusaka, Zambia

Background: Low socioeconomic status has generally been associated with adverse birth outcomes worldwide. Adverse birth outcomes significantly contribute to perinatal morbidity and mortality worldwide with some literatures showing conflicting results. At Women and New-born Hospital in Zambia, this relationship had remained unclear among women who experienced poor neonatal outcome; hence the study was done to explore this association between socioeconomic status and adverse birth outcomes. Methods: A retrospective cohort study was conducted. Secondary data from ZAPPS study that had been collected prospectively between August 2015 and September 201 7 was retrieved. Altogether, 1,450 participants' information was retrieved, out of which 1,084 data records were set out for analysis after excluding those not meeting eligibility criteria. Socioeconomic status was an explanatory variable which was estimated using the standardized wealth score derived from principal component analysis of 14 variables. The wealth quintiles were further categorised into poor and not poor. Response variables were low birth weight, preterm birth and small for gestation age. SPSS version 21 was used for data analysis and p value< 0.05 was significant Results: This study found the incidences of SGA, LBW and preterm births to be 164, 124 and 13 5 per 1000 live births respectively. In survival analysis, the proportion of babies who survived LBW among mothers who were poor was lower (82.9%) compared to babies born to rich mothers (87.5%) (p-value = 0.189). Furthermore, the proportion of babies who survived SGA for the poor was lower (79 .1 % ) compared to babies born to none poor mothers (85.8%) (p-value = 0.032) and preterm birth for the poor (78.4%) compared to babies born to mothers who were rich (83 .6%) (p-value = 0.022). In multiple Cox regression analysis socioeconomic status was not a significant risk factor for SGA ( aHR = 1.08; 95% CI; p=0.099), LBW and preterm birth (aHR = 1.17; 95% CI; p= l.41). However, male babies (aHR = 1.80; 95% CI; p=0.012), domestic violence or abuse during pregnancy (aHR = 3.48; 95% CI [1.59 - 7.34]; p = 0.002) and maternal anaemia (aHR = 2.1; 95% CI; p = 0.019) were risk factors for SGA while prior preterm birth ( aHR = 2.02; 95% CI; p = 0.002), HIV infection (aHR = 1.22; 95% CI; p = 0.040) and anaemia (aHR = 1.37; 95% CI; p = 0.009) were predictors of preterm delivery. Conclusion: There was no statistically significant association between low socioeconomic status and adverse birth outcomes although being pregnant with a male baby, HIV infection, anaemia and prior preterm birth were significantly associated with SGAand preterm

Maternal factors and short-term outcome associated with episiotomy during vaginal delivery at the Women and Newborn Hospital, Lusaka, Zambia

Objective:To explore the maternal factors and short-term outcomes associated with episiotomy during vaginal delivery at Women and Newborn Hospital, Lusaka, Zambia.Materials and Methods:An unmatched case control study was conducted in postnatal wards of Women and New-born hospital in Lusaka, Zambia between November 2019 and April 2020 with convenient sample for the cases and systematic sample for the controls.Asemi-structuredintervieweradministered questionnaire was used and 102 participants (cases) who had episiotomy performed were recruited while 204(controls) werewithoutepisiotomy.Results:Atotal of 306 (102 are cases and 204 are control) were included. Age was found to be a good predictor of episiotomy in that those younger than 18 years were more than seven times likely to have an episiotomy (AOR=7.65; 95%CI 1.36-18.21; p=0.035). It was also found out that primi gravidas were five times likely to have an episiotomy performed compared to parous women (OR=4.96; 95%CI 2.58-9.52; p<0.001). Out of those delivered by a midwife, 73(28.3%) participants had an episiotomy performed compared to 29(60.4%) deliveredbyamedicalofficer.Multivariateregression it was shown that being delivered by a midwife was protective against an episiotomy (OR=0.260; 95%CI 0.14-0.49; p=0.001). Out of the 102 participants who had an episiotomy, only two had third degree tear extension. It was also noted that 99 out of 102 (97%) participants who had an episiotomy experienced post-delivery perineal pain compared to 94 out of 204(46%) of those who had no episiotomies. In univariate analysis, it was found that post-delivery perineal pain was associated with episiotomy (p<0.001). It was further found that those who had an episiotomy performed were about 4 times likely to experience perineal pain post- delivery (OR=3.8; 95%CI 1.2-12.3) Conclusion:Maternal factors associated with episiotomy includedage,parity,method of induction,and the personnel conducting the elivery. Shorttermmaternaloutcomesofepisiotomy were perineal tear extension, and post-delivery perineal pain. It was found that 8.5% of women had undergone an episiotomy done on them. Health professional conducting deliveries should be educated on indications of episiotomy, patient selection during episiotomy and trained on surgical skills to repair episiotomy to reduce morbidity associated the procedure.

Incidence and characteristics of pregnancy-related death across ten low- and middle-income geographical regions: secondary analysis of a cluster randomised controlled trial.

OBJECTIVE: The aim of this article is to describe the incidence and characteristics of pregnancy-related death in low- and middle-resource settings, in relation to the availability of key obstetric resources. DESIGN: This is a secondary analysis of a stepped-wedge cluster randomised controlled trial. SETTING: This trial was undertaken at ten sites across eight low- and middle-income countries in sub-Saharan Africa, India and Haiti. POPULATION: Institutional-level consent was obtained and all women presenting for maternity care were eligible for inclusion. METHODS: Pregnancy-related deaths were collected prospectively from routine data sources and active case searching. MAIN OUTCOME MEASURES: Pregnancy-related death, place, timing and age of maternal death, and neonatal outcomes in women with this outcome. RESULTS: Over 20 months, in 536 233 deliveries there were 998 maternal deaths (18.6/10 000, range 28/10 000-630/10 000). The leading causes of death were obstetric haemorrhage (36.0%, n = 359), hypertensive disorders of pregnancy (20.6%, n = 206), sepsis (14.1%, n = 141) and other (26.5%, n = 264). Approximately a quarter of deaths occurred prior to delivery (28.4%, n = 283), 35.7% (n = 356) occurred on the day of delivery and 35.9% (n = 359) occurred after delivery. Half of maternal deaths (50.6%; n = 505) occurred in women aged 20-29 years, 10.3% (n = 103) occurred in women aged under 20 years, 34.5% (n = 344) occurred in women aged 30-39 years and 4.6% (n = 46) occurred in women aged ≥40 years. There was no measured association between the availability of key obstetric resources and the rate of pregnancy-related death. CONCLUSIONS: The large variation in the rate of pregnancy-related death, irrespective of resource availability, emphasises that inequality and inequity in health care persists. TWEETABLE ABSTRACT: Inequality and inequity in pregnancy-related death persists globally, irrespective of resource availability.

Acyclovir and transmission of HIV-1 from persons infected with HIV-1 and HSV-2.

BACKGROUND: Most persons who are infected with human immunodeficiency virus type 1 (HIV-1) are also infected with herpes simplex virus type 2 (HSV-2), which is frequently reactivated and is associated with increased plasma and genital levels of HIV-1. Therapy to suppress HSV-2 reduces the frequency of reactivation of HSV-2 as well as HIV-1 levels, suggesting that suppression of HSV-2 may reduce the risk of transmission of HIV-1. METHODS: We conducted a randomized, placebo-controlled trial of suppressive therapy for HSV-2 (acyclovir at a dose of 400 mg orally twice daily) in couples in which only one of the partners was seropositive for HIV-1 (CD4 count, > or = 250 cells per cubic millimeter) and that partner was also infected with HSV-2 and was not taking antiretroviral therapy at the time of enrollment. The primary end point was transmission of HIV-1 to the partner who was not initially infected with HIV-1; linkage of transmissions was assessed by means of genetic sequencing of viruses. RESULTS: A total of 3408 couples were enrolled at 14 sites in Africa. Of the partners who were infected with HIV-1, 68% were women, and the baseline median CD4 count was 462 cells per cubic millimeter. Of 132 HIV-1 seroconversions that occurred after randomization (an incidence of 2.7 per 100 person-years), 84 were linked within couples by viral sequencing: 41 in the acyclovir group and 43 in the placebo group (hazard ratio with acyclovir, 0.92, 95% confidence interval [CI], 0.60 to 1.41; P=0.69). Suppression with acyclovir reduced the mean plasma concentration of HIV-1 by 0.25 log(10) copies per milliliter (95% CI, 0.22 to 0.29; P<0.001) and the occurrence of HSV-2-positive genital ulcers by 73% (risk ratio, 0.27; 95% CI, 0.20 to 0.36; P<0.001). A total of 92% of the partners infected with HIV-1 and 84% of the partners not infected with HIV-1 remained in the study for 24 months. The level of adherence to the dispensed study drug was 96%. No serious adverse events related to acyclovir were observed. CONCLUSIONS: Daily acyclovir therapy did not reduce the risk of transmission of HIV-1, despite a reduction in plasma HIV-1 RNA of 0.25 log(10) copies per milliliter and a 73% reduction in the occurrence of genital ulcers due to HSV-2.

The influence of motivational messages on future planning behaviors among HIV concordant positive and discordant couples in Lusaka, Zambia.

In Zambia the HIV/AIDS epidemic has resulted in many single female-headed households. Strong patriarchal laws and customs prevent widows and children from maintaining economic assets. This study examines the impact of a video-based motivational intervention promoting future planning in 1,504 HIV-infected couples in Lusaka, Zambia. Following a group video session, couples randomized to the motivational arm could choose to write a will, identify a guardian for their children and make financial plans. Desirable behaviours modelled in the motivational video were measured at quarterly intervals for a year and compared in intervention and control arms. Demographic measures including age, income and educational status were not associated with planning behaviours. Participation in the intervention was associated with will writing (23% versus 5%) and naming a guardian (32% versus 17%) but not with other planning behaviours. The study demonstrates the ability of motivational messages integrated into HIV VCT to encourage future planning behaviour and points to the need to expand existing HIV and VCT services to meet other non-health needs of those living with HIV.
