Modeling the economic burden of postpartum hemorrhage due to substandard uterotonics in Ghana.

Uterotonics are essential in preventing postpartum hemorrhage (PPH), the leading direct cause of maternal death worldwide. However, uterotonics are often substandard in low- and middle-income countries, contributing to poor maternal health outcomes. This study examines the health and economic impact of substandard uterotonics in Ghana. A decision-tree model was built to simulate vaginal and cesarean section births across health facilities, uterotonic quality and utilization, PPH risk and diagnosis, and resulting health and economic outcomes. We utilized delivery data from Ghana's maternal health survey, risks of health outcomes from a Cochrane review, and E-MOTIVE trial data for health outcomes related to oxytocin quality. We compared scenarios with and without substandard uterotonics, as well as scenarios altering uterotonic use and care-seeking behaviors. We found that substandard uterotonic use contributes to $18.8 million in economic burden annually, including $6.3 million and $4.8 million in out-of-pocket expenditures in public and private sectors, respectively. Annually, the National Health Insurance Scheme bears $1.6 million in costs due to substandard uterotonic use. Substandard uterotonics contribute to $6 million in long-term productivity losses from maternal mortality annually. Improving the quality of uterotonics could reduce 20,000 (11%) PPH cases, 5,000 (11%) severe PPH cases, and 100 (11%) deaths due to PPH annually in Ghana. Ensuring the quality of uterotonics would result in millions of dollars in cost savings and improve maternal health outcomes for the government and families in Ghana. Cost savings from improving uterotonic quality would provide financial protection and help Ghana advance toward Universal Health Coverage.

The drug drought in maternal health: an ongoing predicament.

We developed a comprehensive database of medicines that are used or are being investigated for pre-eclampsia or eclampsia, preterm birth or labour, postpartum haemorrhage, intrauterine growth restriction, and fetal distress and that were in active development between 2000 and 2021. A total of 444 candidates were identified: approximately half of candidates were in active development, two-thirds had been repurposed after initially being used for another condition, and just under half were in preclinical studies. Only 64 candidates were in active late-stage (phase 3) development as of Oct 25, 2021, and given the slow pace of biomedical development, it could take years before any of these products eventually make it to market. A lack of innovation for maternal health medicines persists, and the market continues to fail pregnant individuals. There is a need for collective action from all relevant stakeholders to accelerate investment in the development of new or improved medicines for pregnancy-related conditions.

Factors influencing the participation of pregnant and lactating women in clinical trials: A mixed-methods systematic review.

BACKGROUND: Poor representation of pregnant and lactating women and people in clinical trials has marginalised their health concerns and denied the maternal-fetal/infant dyad benefits of innovation in therapeutic research and development. This mixed-methods systematic review synthesised factors affecting the participation of pregnant and lactating women in clinical trials, across all levels of the research ecosystem. METHODS AND FINDINGS: We searched 8 databases from inception to 14 February 2024 to identify qualitative, quantitative, and mixed-methods studies that described factors affecting participation of pregnant and lactating women in vaccine and therapeutic clinical trials in any setting. We used thematic synthesis to analyse the qualitative literature and assessed confidence in each qualitative review finding using the GRADE-CERQual approach. We compared quantitative data against the thematic synthesis findings to assess areas of convergence or divergence. We mapped review findings to the Theoretical Domains Framework (TDF) and Capability, Opportunity, and Motivation Model of Behaviour (COM-B) to inform future development of behaviour change strategies. We included 60 papers from 27 countries. We grouped 24 review findings under 5 overarching themes: (a) interplay between perceived risks and benefits of participation in women's decision-making; (b) engagement between women and the medical and research ecosystems; (c) gender norms and decision-making autonomy; (d) factors affecting clinical trial recruitment; and (e) upstream factors in the research ecosystem. Women's willingness to participate in trials was affected by: perceived risk of the health condition weighed against an intervention's risks and benefits, therapeutic optimism, intervention acceptability, expectations of receiving higher quality care in a trial, altruistic motivations, intimate relationship dynamics, and power and trust in medicine and research. Health workers supported women's participation in trials when they perceived clinical equipoise, had hope for novel therapeutic applications, and were convinced an intervention was safe. For research staff, developing reciprocal relationships with health workers, having access to resources for trial implementation, ensuring the trial was visible to potential participants and health workers, implementing a woman-centred approach when communicating with potential participants, and emotional orientations towards the trial were factors perceived to affect recruitment. For study investigators and ethics committees, the complexities and subjectivities in risk assessments and trial design, and limited funding of such trials contributed to their reluctance in leading and approving such trials. All included studies focused on factors affecting participation of cisgender pregnant women in clinical trials; future research should consider other pregnancy-capable populations, including transgender and nonbinary people. CONCLUSIONS: This systematic review highlights diverse factors across multiple levels and stakeholders affecting the participation of pregnant and lactating women in clinical trials. By linking identified factors to frameworks of behaviour change, we have developed theoretically informed strategies that can help optimise pregnant and lactating women's engagement, participation, and trust in such trials.

Understanding Domestic Violence Among Older Women in Ukraine: A Secondary Analysis Using Gender-Based Violence Screening Data.

This secondary descriptive analysis sought to understand Gender-Based Violence (GBV), with a focus on Domestic Violence (DV), among older women in Ukraine's conflict setting. Analysis was conducted on a subsample of 150 women aged 60+ from GBV-Information Management System intake data of 12,480 GBV survivors. Fisher's exact tests were used to compare differences in GBV incidents among women who experienced DV compared to other types of GBV. Using United Nations humanitarian and aging frameworks, qualitative analysis was completed following two rounds of coding. Sixty percent of women aged ≥60 experienced DV. Local women were more likely to experience DV versus displaced women (85.6% vs. 48.3%, p < .001). Six core themes emerged: experiencing versus witnessing violence, intergenerational conflict, livelihoods, alcohol, humiliation, and neglect. Deeper understanding of DV among older women in humanitarian settings is needed, strengthening a call to action to prioritize protection against, and prevention of, GBV more broadly among this marginalized group.

Analysis of a maternal health medicines pipeline database 2000-2021: New candidates for the prevention and treatment of fetal growth restriction.

OBJECTIVE: The Accelerating Innovation for Mothers project established a new database of candidate medicines under development between 2000 and 2021 for five pregnancy-related conditions, including fetal growth restriction. The objective was to assess medicines for fetal growth restriction and their potential for clinical use globally. DESIGN: Landscape analysis. SETTING: Global (focus on low- and middle-income countries, LMICs). SAMPLE: Drugs, dietary supplements and biologics under investigation for prevention or treatment of fetal growth restriction. METHODS: A research pipeline database of medicines was created through searching AdisInsight, PubMed and various grant and clinical trial databases. Analysis of clinical and preclinical candidates were descriptive. MAIN OUTCOMES MEASURES: Fetal growth restriction candidates in clinical development were identified and ranked as high, medium or low potential based on prespecified criteria, including efficacy, safety and accessibility. RESULTS: Of the 444 unique candidates in the database across all five pregnancy-related conditions, 63 were for fetal growth restriction. Of these, 31 were in clinical development (phases I, II or III) and 32 were in preclinical development. Three candidates, aspirin, l-arginine and vitamin D, were ranked as having high potential as preventive agents. There were no high-potential candidates for treating fetal growth restriction, although five candidates were ranked as having medium potential: allylestrenol, dalteparin, omega-3 fatty acids, tadalafil, and United Nations International Multiple Micronutrient Antenatal Preparation (UNIMMAP). CONCLUSIONS: l-Arginine, aspirin and vitamin D are promising, high-potential preventative agents for fetal growth restriction. Based on the medicines pipeline, new pharmacological agents for fetal growth restriction are unlikely to emerge in the near future.

Challenges in updating national guidelines and essential medicines lists in Sub-Saharan African countries to include WHO-recommended postpartum hemorrhage medicines.

Despite the 2017 WHO recommendations on tranexamic acid (TXA) for the treatment of postpartum hemorrhage (PPH), the 2018 uterotonic recommendations (which included heat-stable carbetocin (HSC) for the prevention of PPH) and their inclusion in the WHO Essential Medicines List (EML), both drugs are still underused or not used at all to manage PPH in many countries with a high burden. HSC is currently being registered in low- and middle-income countries and its policy inclusion is limited and slow. TXA (also heat stable) is available in many countries but is not registered for PPH treatment, which may have contributed to the delay in its inclusion in national guidelines and EMLs. For both drugs, national guidelines will need to be revised and updated for their optimal uptake. We implemented an advocacy initiative to accelerate the necessary normative policy change to ensure access to quality-assured and heat-stable medicines for the prevention and treatment of PPH in Sub-Saharan African countries. Our initiative aimed to raise awareness of the importance of recently recommended medicines for the prevention and treatment of PPH and support the process to update PPH guidelines and EMLs to include these drugs. We highlight the lessons learned during the initiative, including the challenges and opportunities identified in updating PPH policies at the national level.

Innovations in the prevention and treatment of postpartum hemorrhage: Analysis of a novel medicines development pipeline database.

BACKGROUND: A significant barrier to improving prevention and treatment of postpartum hemorrhage (PPH) is a lack of innovative medicines that meet the needs of women and providers, particularly those in low-and middle-income countries (LMICs). The Accelerating Innovation for Mothers (AIM) project established a new database of candidate medicines under development for five pregnancy-related conditions between 2000 and 2021. OBJECTIVE: To systematically identify and rank candidates for prevention and treatment of PPH. SEARCH STRATEGY: Adis Insight, Pharmaprojects, WHO ICTRP, PubMed, and grant databases were searched to develop the AIM database. SELECTION CRITERIA: AIM database was searched for candidates being evaluated for PPH prevention and treatment, regardless of phase. DATA COLLECTION AND ANALYSIS: Candidates were ranked as high, medium, or low potential based on prespecified criteria. Analysis was primarily descriptive, describing candidates and development potential. MAIN RESULTS: Of the 444 unique candidates, only 39 pertained to PPH. One was high potential (heat-stable/inhaled oxytocin) and three were medium potential (melatonin, vasopressin and dofetilide via nanoparticle delivery). CONCLUSION: The pipeline for new PPH medicines is concerningly limited, lacking diversity, and showing little evidence of novel technologies. Without significant investment in early-phase research, it is unlikely that new products will emerge.

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. RESULTS: Of the 17 unique oxytocin products, 33 individual measurements were made. Only six unique products had adequate content and no related substances exceeding the recommended limits. Of 14 tranexamic acid samples, 10 showed adequate content. One product in Kenya and two products in Nigeria from different manufacturers had a high content of related substances, which classified them as substandard. CONCLUSION: While we were unable to investigate the origin regarding poor manufacturing or poor storage or both, the high number of substandard oxytocin samples is of great concern. Most of the tranexamic acid samples had adequate content but the presence of impurities in multiple products is worrying and requires further study.

An in vitro investigation of the inflammatory response to the strain amplitudes which occur during high frequency oscillation ventilation and conventional mechanical ventilation.

Children randomised in the neonatal period to high frequency oscillatory ventilation (HFOV) or conventional mechanical ventilation (CMV) in the United Kingdom Oscillation study (UKOS) had superior lung function at 11 to 14 years of age. During HFOV, much smaller tidal volumes, but a higher mean airway distending pressure is delivered, hence, a possible explanation for a volume dependent effect on long term lung function could be an increase in inflammation in response to higher tidal volumes and strains. We tested that hypothesis by assessing interleukin-6 (IL-6) and -8 (IL-8) release from A549 alveolar analogue cells following biaxial mechanical strain applied at 0.5 Hz occurring during conditions mimicking strain during CMV (5-20% strain) and conditions mimicking strain during HFOV (17.5% ±â€¯2.5% strain) for up to 4 h. Cyclic strain of 5-20%, occurring during CMV, increased levels of both IL-6 and IL-8 compared to unstrained controls, while 17.5% ±â€¯2.5% strain, occurring during HFOV, was associated with significantly lower levels of IL-6 (46.31 ±â€¯2.66 versus 56.79 ±â€¯3.73 pg/mL) and IL-8 (1340.2 ±â€¯74.9 versus 2522 ±â€¯248 pg/mL) secretion compared to conditions occurring during CMV at four hours. These results may provide a possible explanation for the superior lung function in 11-14-year-old children who had been supported in the neonatal period by HFOV.
