The injectable contraceptives depot medroxyprogesterone acetate and norethisterone enanthate substantially and differentially decrease testosterone and sex hormone binding globulin levels: A secondary study from the WHICH randomized clinical trial.

HIV acquisition risk with norethisterone (NET) enanthate (NET-EN) is reportedly less than for depo-medroxyprogesterone acetate intramuscular (DMPA-IM). We investigated the effects of these progestin-only injectable contraceptives on serum testosterone and sex hormone binding globulin (SHBG) levels, since these may play a role in sexual behavior and HIV acquisition. The open-label WHICH clinical trial, conducted at two sites in South Africa from 2018-2019, randomized HIV-negative women aged 18-40 years to 150 mg DMPA-IM 12-weekly (n = 262) or 200 mg NET-EN 8-weekly (n = 259).

Effects of injectable contraception with depot medroxyprogesterone acetate or norethisterone enanthate on estradiol levels and menstrual, psychological and behavioral measures relevant to HIV risk: The WHICH randomized trial.

Background: Observational data suggest lower HIV risk with norethisterone enanthate (NET-EN) than with depo-medroxyprogesterone acetate intramuscular (DMPA-IM) injectable contraceptives. If confirmed, a switch between these similar injectable methods would be programmatically feasible and could impact the trajectory of the HIV epidemic. We aimed in this paper to investigate the effects of DMPA-IM and NET-EN on estradiol levels, measures of depression and sexual activity and menstrual effects, relevant to HIV risk; and to ascertain whether these measures are associated with estradiol levels.

Maternal postures for fetal malposition in late pregnancy for improving the health of mothers and their infants.

Background: The optimal relationship of the fetus to the mother's birth canal is when the fetus is in the longitudinal lie, cephalic presentation with well-flexed head (vertex presentation), and in the occipito-anterior position. Fetal malposition is described as occipito-posterior (OP) when the back of the fetal head lies posteriorly in the mother's pelvis, and occipito-transverse (OT) when the back of the fetal head lies transversely in the mother's pelvis. The fetal head will often be deflexed and may extend further to a mento-anterior or mento-transverse position, where the chin is anterior or transverse to the maternal pelvis.

Misreporting contraceptive use and the association of peak study progestin levels with weight and BMI among women randomized to the progestin-only injectable contraceptives DMPA-IM and NET-EN.

Progestin-only injectable contraceptives, mainly depo-medroxyprogesterone acetate intramuscular (DMPA-IM), are the most widely used contraceptive methods in sub-Saharan Africa. Insufficient robust data on their relative side-effects and serum concentrations limit understanding of reported outcomes in contraception trials. The WHICH clinical trial randomized HIV-negative women to DMPA-IM (n = 262) or norethisterone enanthate (NET-EN) (n = 259) at two South African sites between 2018-2019.

Novel concepts and improvisation for treating postpartum haemorrhage: a narrative review of emerging techniques.

Background: Most treatments for postpartum haemorrhage (PPH) lack evidence of effectiveness. New innovations are ubiquitous but have not been synthesized for ready access.

Narrative Review: Pubmed 2020 to 2021 was searched on 'postpartum haemorrhage treatment', and novel reports among 755 citations were catalogued.

Novel Concepts for Intrauterine Device Placement at Caesarean Delivery: Description of Technique and Video Recording.

The International Federation of Gynaecology and Obstetrics recommend digital insertion of the copper intrauterine device (IUD) during caesarean delivery and note the risk of thread inclusion in the uterotomy closure and nonvisibility of threads at follow-up. We describe a novel method of inserting the IUD with the insertion straw and directing the lower end of the straw through the cervix for retrieval after the operation, to protect and ensure alignment of the threads. We also describe a simple method of lengthening one thread with part of the other thread, to avoid risks associated with braided suture extensions.

High Levels of Pretreatment HIV-1 Drug Resistance Mutations Among South African Women Who Acquired HIV During a Prospective Study.

Background: Pretreatment HIV drug resistance (PDR) undermines individual treatment success and threatens the achievement of UNAIDS 95-95-95 targets. In many African countries, limited data are available on PDR as detection of recent HIV infection is uncommon and access to resistance testing is limited. We describe the prevalence of PDR among South African women with recent HIV infection from the Evidence for Contraceptive Options and HIV Outcomes (ECHO) Trial.

Brief Report: Quantifiable Plasma Tenofovir Among South African Women Using Daily Oral Pre-exposure Prophylaxis During the ECHO Trial.

Background: HIV endpoint-driven clinical trials provide oral pre-exposure prophylaxis (PrEP) as HIV prevention standard of care. We evaluated quantifiable plasma tenofovir among South African women who used oral PrEP during the Evidence for Contraceptive Options and HIV Outcomes (ECHO) Trial.

Methods: ECHO, a randomized trial conducted in 4 African countries between 2015 and 2018, assessed HIV incidence among HIV-uninfected women, aged 16-35 years, randomized to 1 of 3 contraceptives.

Quality of oxytocin and tranexamic acid for the prevention and treatment of postpartum hemorrhage in Kenya, Nigeria, South Africa, and Tanzania.

Objective: To check the quality of oxytocin and tranexamic acid-two recommended products for prevention and treatment of postpartum hemorrhage (PPH)-used in facilities taking part in an implementation research project to improve PPH diagnosis and management.

Methods: Between September 2020 and August 2021, oxytocin and tranexamic acid products used in the study facilities in Kenya, Nigeria, South Africa, and Tanzania were collected and transported in cold storage for analysis. Samples were analyzed according to the International (oxytocin) and British Pharmacopeia (tranexamic acid) standards.

Calcium for pre-eclampsia prevention: A systematic review and network meta-analysis to guide personalised antenatal care.

Background: Calcium supplementation reduces the risk of pre-eclampsia, but questions remain about the dosage to prescribe and who would benefit most.

Objectives: To evaluate the effectiveness of high (≥1 g/day) and low (<1 g/day) calcium dosing for pre-eclampsia prevention, according to baseline dietary calcium, pre-eclampsia risk and co-interventions, and intervention timing.

Search Strategy: CENTRAL, PubMed, Global Index Medicus and CINAHL, from inception to 2 February 2021, clinical trial registries, reference lists and expert input (CRD42018111239).

Novel side by side Foley catheter balloons for 'extended labour induction': Concept, simulation study and clinical application.

Objective: To introduce the concept of extended or prolonged mechanical balloon labour induction as opposed to pharmacological methods and amniotomy after single balloon expulsion, by the novel use of side-by-side Foley catheter balloons. This method is of particular relevance when there is prior uterine surgery, fetal reserve is uncertain, the risk of vertical infection is high, or facilities for labour monitoring are limited.

Study Design: We conducted simulation studies to compare balloon circumferences and resistance to passage through a simulation cervix between different gauge, fluid distension volume and number of Foley catheters.

"Suction Tube Uterine Tamponade" for treatment of refractory postpartum hemorrhage: Internal feasibility and acceptability pilot of a randomized clinical trial.

Objective: To assess feasibility and acceptability of a novel, low-cost "Suction Tube Uterine Tamponade" (STUT) treatment for refractory postpartum hemorrhage (PPH).

Methods: We allocated patients with refractory PPH by randomly ordered envelopes to STUT or routine uterine balloon tamponade (UBT, Ellavi free-flow system) in 10 hospitals in South Africa. In the STUT group, a 24FG Levin stomach tube was inserted into the uterine cavity and vacuum created with a vacuum pump or manual vacuum aspiration syringe.

Behavioral effects of different contraceptive methods and HIV acquisition: an ancillary study of the ECHO randomized trial.

Background: The ECHO trial randomised 7829 women to depot medroxyprogesterone acetate (DMPA-IM), the copper intrauterine device (IUD) and the levonorgestrel (LNG) implant (1:1:1) and found no clear difference in HIV incidence between these three groups. We have previously hypothesized that oligo-amenorrhoea induced by DMPA-IM may have a protective effect on HIV acquisition. The aim of this ancillary study was to assess the effects of DMPA-IM, the IUD and the LNG implant on menstrual symptoms and sexual behavior and to correlate these with HIV acquisition.

The effect of calcium supplementation on blood pressure in non-pregnant women with previous pre-eclampsia: A randomized placebo-controlled study.

Background: Low dietary calcium is associated with the hypertensive disorders of pregnancy, and evidence suggests that the risks associated with pre-eclampsia are reduced by calcium supplementation. In the general (non-pregnant) population, low dietary calcium intake is associated with hypertension with inconsistent evidence that calcium supplementation may reduce blood pressure. Women with pre-eclampsia are also at risk of hypertension later in life.

Calcium-fortified foods in public health programs: considerations for implementation.

Low calcium intake is common worldwide and can result in nutritional rickets in children and osteomalacia in adults. Calcium-fortified foods could improve calcium intake. However, there is limited calcium fortification experience, with technical and practical issues that may hamper its adoption.

Current calcium fortification experiences: a review.

Low dietary calcium is very common in many populations, contributing to nutritional rickets/osteomalacia in children/adults and increasing the risk of several health problems. Calcium is a nutrient of concern as the recommended nutrient requirements are difficult to meet in the absence of dairy products. The provision of culturally acceptable calcium-fortified foods may improve calcium intake when it is a feasible and cost-effective strategy in a particular setting.

Integrating oral PrEP delivery among African women in a large HIV endpoint-driven clinical trial.

Introduction: Global guidelines emphasize the ethical obligation of investigators to help participants in HIV-endpoint trials reduce HIV risk by offering an optimal HIV prevention package. Oral pre-exposure prophylaxis (PrEP) has increasingly become part of state-of-the-art HIV prevention. Here we describe the process of integrating oral PrEP delivery into the HIV prevention package of the Evidence for Contraceptive Options and HIV Outcomes (ECHO) Trial.

Regulatory and Policy-Related Aspects of Calcium Fortification of Foods. Implications for Implementing National Strategies of Calcium Fortification.

Daily calcium intake is well below current recommendations in most low- and middle-income countries (LMICs). Calcium intake is usually related to bone health, however an adequate calcium intake has also been shown to reduce hypertensive disorders of pregnancy, lower blood pressure and cholesterol values, and to prevent recurrent colorectal adenomas. Food fortification of foods has been identified as a cost-effective strategy to overcome micronutrient gaps in public health.

Novel suction tube uterine tamponade for treating intractable postpartum haemorrhage: description of technique and report of three cases.

Uterine balloon tamponade (UBT) is widely used to treat postpartum haemorrhage (PPH). Randomised trials of UBT are scarce: those of improvised condom UBT in low-resource settings found more harm than good. Uterine suction tamponade (UST) is more aligned with the physiological mechanism of uterine haemostasis (contraction), but purpose-designed devices may be unaffordable or unavailable when needed.

Randomized feasibility study of suction-tube uterine tamponade for postpartum hemorrhage.

Objective: To identify an inexpensive catheter suitable for uterine suction tamponade (UST) for postpartum hemorrhage and assess its functionality.

Methods: Randomized, single-center, double-blind feasibility study in East London, South Africa, among 45 women undergoing cesarean delivery between October and November 2018. A search of medical supply websites for catheters with predefined characteristics (inexpensive, flexible, wide-bore, circumferentially-arranged side apertures, rounded tip) identified the FG36 Levin stomach tube.
