    Acceptability and feasibility of mHealth and community-based directly observed antiretroviral therapy to prevent mother-to-child HIV transmission in South African pregnant women under Option B+ : an exploratory study
    (Dove Medical Press, 2016) Nachega, Jean B.; Skinner, Donald; Jennings, Larissa; Magidson, Jessica F.; Altice, Frederick L.; Burke, Jessica G.; Lester, Richard T.; Uthman, Olalekan A.; Knowlton, Amy R.; Cotton, Mark F.; Anderson, Jean R.; Theron, Gerhard B.
    ENGLISH SUMMARY : Objective: To examine the acceptability and feasibility of mobile health (mHealth)/short message service (SMS) and community-based directly observed antiretroviral therapy (cDOT) as interventions to improve antiretroviral therapy (ART) adherence for preventing mother-to-child human immunodeficiency virus (HIV) transmission (PMTCT). Design and methods: A mixed-method approach was used. Two qualitative focus group discussions with HIV-infected pregnant women (n=20) examined the acceptability and feasibility of two ART adherence interventions for PMTCT: 1) SMS text messaging and 2) patient-nominated cDOT supporters. Additionally, 109 HIV-infected, pregnant South African women (18–30 years old) receiving PMTCT services under single-tablet antiretroviral therapy regimen during pregnancy and breastfeeding and continuing for life (“Option B+”) were interviewed about mobile phone access, SMS use, and potential treatment supporters. Setting: A community primary care clinic in Cape Town, South Africa. Participants: HIV-infected pregnant women. Main outcomes: Acceptability and feasibility of mHealth and cDOT interventions. Results: Among the 109 women interviewed, individual mobile phone access and SMS use were high (>90%), and 88.1% of women were interested in receiving SMS ART adherence support messages such as reminders, motivation, and medication updates. Nearly all women (95%) identified at least one person close to them to whom they had disclosed their HIV status and would nominate as a cDOT supporter. Focus group discussions revealed that cDOT supporters and adherence text messages were valued, but some concerns regarding supporter time availability and risk of unintended HIV status disclosure were expressed. Conclusion: mHealth and/or cDOT supporter as interventions to improve ART adherence are feasible in this setting. However, safe HIV status disclosure to treatment supporters and confidentiality of text messaging content about HIV and ART were deemed crucial.

    A case series of post-partum haemorrhage managed using Ellavi uterine balloon tamponade in a rural regional hospital
    (AOSIS, 2021-05) Theron, Gerhard B.; Mpumlwana, Vulikaya
    Uterine balloon tamponade (UBT) should be attempted once emergency measures have been applied and medical treatment for post-partum haemorrhage (PPH) resulting from an atonic uterus has failed. Sinapi Biomedical (Pty) Ltd developed the Ellavi UBT, a free-flow pressure-controlled UBT unit. The device is affordable for use in lesser-resourced countries. A case series of Ellavi UBT used by medical officers in a rural regional hospital without specialist supervision was conducted. This case series was conducted in St Elizabeth’s Hospital in Lusikisiki, South Africa. The hospital serves as the regional hospital for the Ingquza Hill Subdistrict in the Eastern Cape Province. The Nelson Mandela Academic Hospital (NMAH) in Mthatha is the tertiary referral hospital. Workshops were conducted on the use of Ellavi UBT, and devices were made freely available to the hospital. The case series included 10 patients. Six patients delivered by caesarean section, and four had normal vertex deliveries. All patients had additional oxytocin infusions, and eight patients received misoprostol. Following the insertion and inflation of the Ellavi UBT, the PPH stopped in seven patients, was much reduced in one patient and reduced in one patient. In one case, the Ellavi UBT had no effect on the bleeding. All 10 patients were referred to the NMAH. All patients in the case series had good outcomes. The insertion of the Ellavi UBT and subsequent referral proved to be feasible in a rural regional hospital. All patients included in the case series arrived at the referral hospital and had a good outcome.

    Stillbirth rates in singleton pregnancies in a stable population at Karl Bremer and Tygerberg hospitals over 50 years
    (Health & Medical Publishing Group, 2013-09-03) Odendaal, Hein J.; Gebhardt, G. Stefan; Theron, Gerhard B.
    Objectives. To determine the changes in stillbirth rates in singleton pregnancies in a stable population over a period of 50 years. Methods. Stillbirth rates for singleton pregnancies where the fetus weighed 1 000 g or more were collected from 1962 to 2011. From 1972 to 2011, rates included fetuses weighing 500 g or more at birth. Results. When the birth weight was 1 000 g or more the stillbirth rate declined from 70 to 12.6 per 1 000 births, and when the birth weight was 500 g or more it dropped from 34.2 to 24.5. The decline was very much slower towards the end of the study period. Conclusion. To achieve further sustained reductions in stillbirth rates, healthcare workers should continue to emphasise quality of healthcare, but they should also address and prevent specific conditions associated with stillbirth, such as smoking and drinking during pregnancy.
