The economic consequences of obstetric fistula: A systematic search and narrative review.

BACKGROUND: Obstetric fistula develops from obstructed labor and is a devastating condition with significant consequences across several domains of a woman's life. This study presents a narrative review of the evidence on the economic consequences of obstetric fistula. METHODS: Three databases were searched, and search results were limited to English language papers published after 2003. Search results were reviewed for relevance based on title and abstract followed by full text review using specific inclusion and exclusion criteria. Bibliographies of papers were also scanned to identify relevant papers for inclusion. Data were extracted under three categories (defined a priori): the economic consequences of having the condition, the economic consequences of seeking care, and the macroeconomic impacts. RESULTS: The search returned 517 unique papers, 49 of which were included after screening. Main findings identified from the studies include women losing their jobs, becoming dependent on others, and losing financial support when relationships are lost. Seeking care was economically costly for families or unaffordable entirely. There were no studies describing the impact of fistula on national economies. CONCLUSION: Economic consequences of obstetric fistula are multifaceted, pervasive, and are intertwined with the physical and psychosocial consequences of the condition. Understanding these consequences can help tailor existing fistula programs to better address the impacts of the condition. Further research to address the dearth of literature describing the macroeconomic impact of obstetric fistula will be critical to enhance the visibility of this condition on the health agendas of countries.

The burden of long bone fracture and health system response in Malawi: A scoping review.

OBJECTIVES: Fractures pose serious health and socioeconomic consequences for individuals, their families, and societies more broadly. In many low-resource settings, case fatality and long-term sequelae after a fracture remain high due to individual- and system-level barriers affecting timely access to care. This scoping review explored the burden of fractures in Malawi using long bone fracture (LBF) as a case study by examining the epidemiology of these injuries, their consequences, and the accessibility of quality healthcare. Our aim is to not only describe the scale of the issue but to identify specific interventions that can help address the challenges faced in settings with limited resources and healthcare budgets. METHODS: A scoping review methodology was adopted with a narrative synthesis of results. We searched five databases to identify relevant literature and applied the "Three Delays" model and the WHO's Building Blocks Framework to analyse findings on the accessibility of fracture care. RESULTS: Fractures most often occurred among young males, with falls being the leading cause, constituting between 5 and 35 % of the total burden of injuries. Fractures were typically managed without surgery despite consistent local evidence showing surgical treatment was superior to conservative management in terms of length of hospital stay and bone healing. Poor functional, economic, and social outcomes were noted in fracture patients, especially after conservative treatment. A lack of trust in the health system, financial barriers, poor transport, and road infrastructure, and interfacility transfers were identified as barriers to care-seeking. Factors challenging the provision of appropriate care included governance issues, poor health infrastructure, financial constraints, and shortage of supplies and human resources. CONCLUSIONS: To the best of our knowledge, this review represents the first comprehensive examination of the state of LBF and the health system's response in Malawi. The findings underscore the pressing need for a national trauma registry to accurately determine the actual burden of injuries and support a tailored approach to fracture care in Malawi. It is further evident that the health system in Malawi must be strengthen across all six building blocks to address obstacles to equitable access to high-quality fracture care.

Exploring the role of ex vivo metabolism on blood and plasma measurements of oxytocin among women in the third stage of labour: A post hoc study.

AIMS: To examine the role of ex vivo oxytocin metabolism in post-dose peptide measurements. METHODS: The stability of oxytocin (Study 1) and oxytocinase activity (Study 2) in late-stage pregnancy blood was quantified using liquid-chromatography tandem mass-spectrometry (LC-MS/MS) and a fluorogenic assay, respectively. Analyses were conducted using blood from pregnant women (>36 weeks gestation) evaluated in lithium heparin (LH), ethylenediaminetetraacetic acid (EDTA) and BD P100 blood collection tubes with or without protease inhibitors. In addition, plasma oxytocin concentrations following administration of oxytocin 240 IU inhaled, 5 IU intravenous or 10 IU intramuscular in women in third stage of labour (TSL) were analysed using enzyme-linked immunosorbent assay (ELISA) and LC-MS/MS to understand how quantified peptide concentrations differ between these analytical methods (Study 3). RESULTS: Study 1: Oxytocin was stable in blood collected into EDTA tubes with or without protease inhibitors but not in LH tubes. Study 2: Blood collected into all EDTA-containing collection tubes led to near-complete inhibition of oxytocinase (≤100 min). In plasma, a 35% reduction in oxytocinase activity was observed in LH tubes with EDTA added. In plasma from late-stage pregnancy compared to nonpregnant participants, the oxytocinase activity was approximately 11-fold higher. Study 3: Plasma oxytocin concentrations from nonpregnant or women in TSL following exogenous oxytocin administration were ≤33 times higher when analysed using ELISA vs. LC-MS/MS methods. CONCLUSIONS: Collection of blood from late-stage pregnant women into tubes containing EDTA inhibits oxytocinase effectively stabilizing oxytocin, suggesting low concentrations of oxytocin after dose administration reflect rapid in vivo metabolism.

Cost-effectiveness of inhaled oxytocin for prevention of postpartum haemorrhage: a modelling study applied to two high burden settings.

BACKGROUND: Access to oxytocin for prevention of postpartum haemorrhage (PPH) in resource-poor settings is limited by the requirement for a consistent cold chain and for a skilled attendant to administer the injection. To overcome these barriers, heat-stable, non-injectable formulations of oxytocin are under development, including oxytocin for inhalation. This study modelled the cost-effectiveness of an inhaled oxytocin product (IHO) in Bangladesh and Ethiopia. METHODS: A decision analytic model was developed to assess the cost-effectiveness of IHO for the prevention of PPH compared to the standard of care in Bangladesh and Ethiopia. In Bangladesh, introduction of IHO was modelled in all public facilities and home deliveries with or without a skilled attendant. In Ethiopia, IHO was modelled in all public facilities and home deliveries with health extension workers. Costs (costs of introduction, PPH prevention and PPH treatment) and effects (PPH cases averted, deaths averted) were modelled over a 12-month program. Life years gained were modelled over a lifetime horizon (discounted at 3%). Cost of maintaining the cold chain or effects of compromised oxytocin quality (in the absence of a cold chain) were not modelled. RESULTS: In Bangladesh, IHO was estimated to avert 18,644 cases of PPH, 76 maternal deaths and 1954 maternal life years lost. This also yielded a cost-saving, with the majority of gains occurring among home deliveries where IHO would replace misoprostol. In Ethiopia, IHO averted 3111 PPH cases, 30 maternal deaths and 767 maternal life years lost. The full IHO introduction program bears an incremental cost-effectiveness ratio (ICER) of between 2 and 3 times the per-capita Gross Domestic Product (GDP) ($1880 USD per maternal life year lost) and thus is unlikely to be considered cost-effective in Ethiopia. However, the ICER of routine IHO administration considering recurring cost alone falls under 25% of per-capita GDP ($175 USD per maternal life-year saved). CONCLUSIONS: IHO has the potential to expand access to uterotonics and reduce PPH-associated morbidity and mortality in high burden settings. This can facilitate reduced spending on PPH management, making the product highly cost-effective in settings where coverage of institutional delivery is lagging.

Qualitative formative implementation research to inform introduction of a new essential medicine.

BACKGROUND: The launch of novel pharmaceuticals in the developing world faces significant barriers that can delay or ultimately inhibit uptake. Implementation research can provide an understanding of factors influencing the introduction and scale up of a new product and thus can inform implementation strategy development. OBJECTIVE: This study explored the factors likely to influence introduction of a novel oxytocin formulation for the prevention of postpartum hemorrhage in Ethiopia. METHODS: Qualitative research methods were used to assess barriers and enablers associated with pre-determined domains: regulatory approval, pricing, supply and demand side advocacy, policy inclusion, end-user training and drug supply. Data were collected through focus group discussions and in-depth interviews with community members, healthcare providers and key informants. Verbatim transcripts were translated to English and analyzed using a thematic content framework. RESULTS: Approval from stringent regulatory bodies was an enabler for gaining national regulatory approval. Purchasers (government and patients) expressed price sensitivity but would be willing to pay a price comparable to or higher than current alternatives if improved quality is delivered. Endorsement from the World Health Organization was described as critical for national policy inclusion. Supply side advocacy should be directed towards the Ministry of Health, which is receptive to advice from reputable agencies with whom they have an existing relationship. Demand side advocacy should be delivered through existing health system channels such as Ministry of Health authorities (for healthcare workers) and community health workers (for community members). The requirement to purchase the product directly from a single manufacturer was highlighted as a potential barrier for entry into the local supply chain. CONCLUSION: This study highlighted several barriers and enablers associated with the introduction of a new drug product into the health system of Ethiopia. An advanced understanding of these influences can inform the design of locally-appropriate implementation strategies.

Knowledge, perception and practice towards oxytocin stability and quality: A qualitative study of stakeholders in three resource-limited countries.

BACKGROUND: Oxytocin is the gold standard drug for the prevention of postpartum haemorrhage, but limitations in cold chain systems in resource-constrained settings can severely compromise the quality of oxytocin product available in these environments. This study investigated the perspectives and practices of stakeholders in low and lower-middle income countries towards oxytocin, its storage requirements and associated barriers, and the quality of product available. METHODS: Qualitative inquiries were undertaken in Ethiopia, India and Myanmar, where data was collected through Focus Group Discussions (FGDs) and In-Depth Interviews (IDIs). A total of 12 FGDs and 106 IDIs were conducted with 158 healthcare providers (pharmacists, midwives, nurses, doctors and obstetricians) and 40 key informants (supply chain experts, program managers and policy-makers). Direct observations of oxytocin storage practices and cold chain resources were conducted at 51 healthcare facilities. Verbatim transcripts of FGDs and IDIs were translated to English and analysed according to a thematic content analysis framework. FINDINGS: Stakeholder awareness of oxytocin heat sensitivity and the requirement for cold storage of the drug was widespread in Ethiopia but more limited in Myanmar and India. A consistent finding across all study regions was the significant barriers to maintaining a consistent cold chain, with the lack of refrigeration facilities and unreliability of electricity cited as major challenges. Perceptions of compromised oxytocin quality were expressed by some stakeholders in each country. CONCLUSION: Knowledge of the heat sensitivity of oxytocin and the potential impacts of inconsistent cold storage on product quality is not widespread amongst healthcare providers, policy makers and supply chain experts in Myanmar, Ethiopia and India. Targeted training and advocacy messages are warranted to emphasise the importance of cold storage to maintain oxytocin quality.

Androgens regulate adenylate cyclase activity and intracellular calcium in stromal cells derived from human prostate.

BACKGROUND: Increased smooth muscle tone is a significant component of benign prostatic hyperplasia, the onset of which correlates with age and declining serum testosterone levels. This study investigates the effects of androgens on key regulators of smooth muscle tone: intracellular calcium ([Ca(2+)](i)) and cyclic adenosine monophosphate (cAMP) in human cultured prostatic stromal cells (HCPSC). METHODS: HCPSC were cultured in the absence or presence of dihydrotestosterone (DHT; 3, 30, and 300 nM) or testosterone (0.3-300 nM) alone or in the presence of flutamide (10 microM). Changes in [Ca(2+)](i) were determined in FURA-2AM (10 microM) loaded cells. Changes in cAMP were determined by Alpha Screen(R) assay. RESULTS: Up to 32% of cultured cells exhibited spontaneous elevations of [Ca(2+)](i). The frequency of these elevations was reduced by nifedipine (10 microM), ryanodine (1 microM), and the adenylate cyclase inhibitor MDL 12,330A (20 microM). Compared to steroid-free cells, a 3-day incubation of cells with testosterone (only 3 nM) elevated basal, but not peak [Ca(2+)](i). In the presence of flutamide, all concentrations of testosterone tested elevated basal, but not peak [Ca(2+)](i). DHT (30 and 300, but not 3 nM) lowered peak and basal [Ca(2+)](i). Increased testosterone concentration dependently decreased resting cell cAMP (pIC(50): 7.64 +/- 0.29 nM). CONCLUSIONS: These findings demonstrate that some HCPSC have the ability to spontaneously and transiently elevate [Ca(2+)](i). The magnitude of these [Ca(2+)](i) peaks, along with resting levels of calcium and cAMP, appear to be regulated by androgens.
