Comparability of an innovative Doppler ultrasound fetal heart rate monitor to a pinard fetal stethoscope using cardiotocography as a standard to assess the fetal heart rate in singleton pregnancies during labour at Mowbray Maternity Hospital

Includes abstract.Includes bibliographical references.Almost four million babies die in the first four weeks of life per year worldwide, most from preventable causes. In addition a million babies die during labour and delivery (Lawn J et al., 2005). In South Africa, ‘intrapartum hypoxia and birth trauma’ are among the top three causes of perinatal deaths. Severe intrapartum hypoxia is often preventable with appropriate maternal and fetal monitoring in labour. However, this remains a challenge in under-resourced settings, due to difficulties that accompany the use of a Pinard Fetal Stethoscope (PFS) which include user-dependence and lack of evidence based standardisation in taking measurements with it. Although intermittent fetal heart monitoring is as effective as continuous electronic monitoring in low risk labours (Banta DH and Thacker, 2001), the search is for reliable, robust and cheaper fetal monitoring devices. The innovative crank powered Doppler Ultrasound Fetal Heart Rate Monitor (DUFHRM) developed by Power-free Education and Technology is robust, cheaper and designed for use even in settings with no or erratic access to mains electricity and replaceable batteries, and overcomes some of the challenges that come with the use of PFS (Banta DH and Thacker, 2001). The aim of the study was to assess the accuracy of Fetal Heart Rates (FHRs)taken with the DUFHRM compared to FHRs taken with a PFS using a Cardiotocography (CTG) as a standard fetal heart rate monitoring device. This was a comparative diagnostic study conducted at Mowbray Maternity Hospital, a public sector maternity hospital in Cape Town during 2012. Women with singleton pregnancies in the active phase of the first stage of labour, who had consented to participation, were enrolled in the study. Paired readings of FHRs were taken with a DUFHRM and a PFS, by two midwives and also with a CTG during the active phase of the first stage of labour before and after two preferably consecutive uterine contractions. The midwives were blinded to the CTG measurements by silencing the CTG and turning it away from their view. The FHRs taken with a PFS were done over a 60 second period in accordance with the guidelines from professional bodies (ACOG, 1995, RANZCOG, 2002, RCOG, 2001a, Liston R et al., 2002) The DUFHRM and CTG readings were made at the start and end of each 60 second period of PFS monitoring. The proportion agreement of FHRs taken with a DUFHRM to FHRs recorded with a CTG, and the proportion agreement of FHRs taken with a PFS to FHRs recorded with a CTG were determined and compared using McNemar Exact Significance Probability test (mcc)

High rates of cervical cancer among HIV-infected women at a referral hospital in Malawi

Cervical cancer is the most common cancer among women in Malawi. National guidelines recommend screening women aged 30–45 years every five years; however, no specific recommendations exist for women with HIV. We aimed to assess the frequency of high-grade dysplasia (CIN 2 or CIN3) and cervical cancer among women in central Malawi and to examine associations with CIN2+ (CIN2/3 or cancer)

Family planning knowledge, experiences and reproductive desires among women who had experienced a poor obstetric outcome in Lilongwe Malawi: a qualitative study

Abstract Background Perinatal mortality is unacceptably high in low-income countries, including Malawi. Use of family planning to encourage birth spacing may optimize outcomes for subsequent pregnancies. However, the reproductive desires and family planning knowledge of women who have experienced a stillbirth or neonatal death in resource-poor settings are not well understood. Methods We examined family planning knowledge, contraceptive practices and barrier to contraceptive use among women who had experienced a poor obstetric outcome at Bwaila Hospital in Lilongwe, Malawi. We performed individual in-depth interviews or through focus group discussion with women who had experienced a stillbirth or early neonatal death, 4–8 weeks after their delivery. NVivo software was used to analyze data for recurrent patterns and themes, and central ideas were extracted to identify the data’s core meanings. Results We interviewed 46 women who had experienced a poor obstetric outcome. Overall, women were aware of both modern and traditional family planning methods, and the majority were in favour of modern versus traditional methods. They also had knowledge about risks for future complications if they have a short inter-pregnancy interval. However, they faced conflict about whether to use family planning methods for their health, as suggested by their relatives and friends, or to have another child to fulfil their husband’s desire, especially among those with no living child. Some had fear about side effects, while others were concerned that use of family planning methods without involving the husband could bring misunderstandings within the family. A number of women had misconceptions about family planning methods, which also served as a barrier to their use. Conclusion Although women with a poor obstetric outcome are aware of modern family planning and its health benefits after their delivery, their decision to use a method is complicated by their own desire to protect their own health and the husband’s desire for a child, particularly among those women with no living children coupled with fear of side effects and misconceptions. These findings suggest the importance of counselling both the affected woman and her husband about the benefits of family planning use, even after a poor obstetric outcome, to jointly choose the method they feel comfortable to use and dispel any misconceptions.

Influences on birth spacing intentions and desired interventions among women who have experienced a poor obstetric outcome in Lilongwe Malawi: a qualitative study

Abstract Background Stillbirth and neonatal mortality are very high in many low-income countries, including Malawi. Use of family planning to encourage birth spacing may optimize outcomes for subsequent pregnancies. However, reproductive desires and influences on birth spacing preferences of women who have experienced a stillbirth or neonatal death in low-resource settings are not well understood. Methods We conducted a qualitative study using 20 in-depth interviews and four focus group discussions with women who had experienced a stillborn baby or early neonatal death to explore attitudes surrounding birth spacing and potential interventions to promote family planning in this population. Qualitative data were analyzed for recurrent patterns and themes and central ideas were extracted to identify their core meanings. Results Forty-six women participated in the study. After experiencing a stillbirth or neonatal death, most women wanted to wait to become pregnant again but women with living children wished to wait for longer periods of time than those with no living children. Most women preferred birth spacing interventions led by clinical providers and inclusion of their spouses. Conclusions Many influences on family size and birth spacing were noted in this population, with the most significant influencing factor being the spouse. Interventions to promote birth spacing and improve maternal and neonatal health in this population need to involve male partners and knowledgeable health care providers to be effective.

Experiences of women participating in a human papillomavirus-based screen-triage-and treat strategy for cervical cancer prevention in Malawi

Objective To explore the experiences of Malawian women who underwent a human papillomavirus (HPV)-based screen-triage-treat algorithm for cervical cancer (CxCa) prevention. This algorithm included GeneXpert® HPV testing of self-collected vaginal samples, visual inspection with acetic acid (VIA) and colposcopy for HPV-positive women, and thermal ablation of ablation-eligible women. Method In-depth interviews were conducted with participants of a trial that evaluated the feasibility of a HPV-based screen-triage-treat algorithm among women living with HIV and HIV negative women in Lilongwe, Malawi. Participants were recruited from 3 groups: 1) HPV-negative; 2) HPV-positive/VIA-negative; 3) HPV-positive/VIA-positive and received thermal ablation. Interviews explored baseline knowledge of CxCa and screening, attitudes towards self-collection, and understanding of test results. Content analysis was conducted using NVIVO v12. Results Thematic saturation was reached at 25 interviews. Advantages of HPV self-collection to participants were convenience of sampling, same-day HPV results and availability of same-day treatment. There was confusion surrounding HPV-positive/VIA-negative results, as some participants still felt treatment was needed. Counseling, and in particular anticipatory guidance, was key in helping participants understand complex screening procedures and results. Overall, participants expressed confidence in the HPV screen-triage-treat strategy. Discussion HPV testing through self-collected samples is a promising tool to increase CxCa screening coverage. A multi-step screening algorithm utilizing HPV self-testing, VIA triage and thermal ablation treatment requires proper counseling and anticipatory guidance to improve patient understanding. Incorporating thorough counseling in CxCa screening programs can change women’s perspectives about screening, build trust in healthcare systems, and influence healthcare seeking behavior towards routine screening and prevention

A randomized clinical trial on the effects of progestin contraception in the genital tract of HIV-infected and uninfected women in Lilongwe, Malawi: Addressing evolving research priorities

Hormonal contraception is central in the prevention of unintended pregnancy; however there are concerns that certain methods may increase the risk of HIV acquisition and transmission. Hormonal contraceptives may modify the genital mucosa in several ways, however the mechanisms are incompletely understood. Few studies have examined genital HIV shedding prospectively before and after initiation of hormonal contraception. The effects of hormonal contraception on genital HIV shedding in the setting of antiretroviral therapy (ART) are also unknown. We designed a pilot clinical trial in which HIV-infected and uninfected women were randomized to either depot medroxyprogesterone acetate (DMPA) injectable or levonorgestrel (LNG) implant in Lilongwe, Malawi. The objectives were to: 1) assess the effect and compare the impact of type of progestin contraception (injectable versus implant) on HIV genital shedding among HIV-infected women, 2) assess the effect and compare the impact of type of progestin contraception on inflammatory/immune markers in the genital tract of both HIV-infected and uninfected women, and 3) assess the interaction of progestin contraception and ART by examining contraceptive efficacy and ART efficacy. An additional study aim was to determine the feasibility and need for a larger study of determinants of HIV transmissibility and acquisition

Pregnancy outcomes of women conceiving on antiretroviral therapy (ART) compared to those commenced on ART during pregnancy

CITATION: Theron, G. et al. 2021. Pregnancy Outcomes of Women Conceiving on Antiretroviral Therapy (ART) Compared to Those Commenced on ART During Pregnancy. Clinical infectious diseases, 73(2): e312–e320. doi:10.1093/cid/ciaa805The original publication is available at https://academic.oup.com/cid/Background: Globally, the number of infected women of childbearing age living with human immunodeficiency virus (HIV) and conceiving on antiretroviral therapy (ART) is increasing. Evidence of ART safety at conception and during pregnancy and adverse pregnancy outcomes remains conflicting. The Promoting Maternal and Infant Survival Everywhere (PROMISE) 1077 breastfeeding (BF) and formula feeding (FF) international multisite trials provide an opportunity to examine the impact of ART at conception on pregnancy outcomes with subsequent pregnancies. Methods: The PROMISE 1077BF/1077FF trials were designed to address key questions in the management of HIV-infected women who did not meet clinical guidelines for ART treatment during the time of the trials. After the period of risk of mother-to-child transmission was over, women were randomized to either continue or discontinue ART. We compared subsequent pregnancy outcomes of nonbreastfeeding women randomized to continue ART following delivery, or breastfeeding women randomized to continue ART following breastfeeding cessation who conceived while on ART to women randomized to discontinue ART, who restarted ART after pregnancy was diagnosed. Results: Pregnancy outcomes of 939 subsequent pregnancies of 826 mothers were recorded. The intention-to-treat analyses showed increased incidence of low birth weight (<2500 g) for women who conceived while on ART (relative risk, 2.65 [95% confidence interval {CI}, 1.20-5.81]), and also a higher risk of spontaneous abortion, stillbirth, or neonatal death (hazard ratio, 1.40 [95% CI, .99-1.98]) compared to women who restarted ART after they were found to be pregnant during trial follow-up. Conclusions: We found an increased risk for adverse pregnancy outcomes in women conceiving on ART, emphasizing the need for improved obstetric and neonatal care for this group.

HPV vaccination in Africa in the COVID-19 era: a cross-sectional survey of healthcare providers’ knowledge, training, and recommendation practices

IntroductionAlthough the burden of cervical cancer in Africa is highest, HPV vaccination coverage remains alarmingly low in this region. Providers’ knowledge and recommendation are key drivers of HPV vaccination uptake. Yet, evidence about providers’ knowledge and recommendation practices about the HPV vaccine against a backdrop of emerging vaccine hesitancy fueled by the COVID-19 pandemic is lacking in Africa.MethodsA cross-sectional study was conducted in 2021–2022 among healthcare providers involved in cervical cancer prevention activities in Africa. They were invited to report prior training, the availability of the HPV vaccine in their practice, whether they recommended the HPV vaccine, and, if not, the reasons for not recommending it. Their knowledge about the HPV vaccine was assessed through self-reporting (perceived knowledge) and with three pre-tested knowledge questions (measured knowledge).ResultsOf the 153 providers from 23 African countries who responded to the survey (mean age: 38.5 years, SD: 10.1), 75 (54.0%) were female and 97 (63.4%) were based In countries with national HPV immunization programs. Overall, 57 (43.8%) reported having received prior training on HPV vaccine education/counseling, and 40 (37.4%) indicated that the HPV vaccine was available at the facility where they work. Most respondents (109, 83.2%) reported recommending the HPV vaccine in their practice. Vaccine unavailability (57.1%), lack of effective communication tools and informational material (28.6%), and need for adequate training (28.6%) were the most commonly reported reasons for not recommending the HPV vaccine. While 63 providers (52.9%) reported that their knowledge about HPV vaccination was adequate for their practice, only 9.9% responded correctly to the 3 knowledge questions.ConclusionTo increase HPV vaccination coverage and counter misinformation about this vaccine in Africa, adequate training of providers and culturally appropriate educational materials are needed to improve their knowledge of the HPV vaccine and to facilitate effective communication with their patients and the community
