Background: Large-scale improvement programmes are a frequent response to quality and safety problems in health systems globally, but have mixed impact. The extent to which they meet criteria for programme quality, particularly in relation to transparency of reporting and evaluation, is unclear., Aim: To identify large-scale improvement programmes focused on intrapartum care implemented in English National Health Service maternity services in the period 2010-2023, and to conduct a structured quality assessment., Methods: We drew on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidance to inform the design and reporting of our study. We identified relevant programmes using multiple search strategies of grey literature, research databases and other sources. Programmes that met a prespecified definition of improvement programme, that focused on intrapartum care and that had a retrievable evaluation report were subject to structured assessment using selected features of programme quality., Results: We identified 1434 records via databases and other sources. 14 major initiatives in English maternity services could not be quality assessed due to lack of a retrievable evaluation report. Quality assessment of the 15 improvement programmes meeting our criteria for assessment found highly variable quality and reporting. Programme specification was variable and mostly low quality. Only eight reported the evidence base for their interventions. Description of implementation support was poor and none reported customisation for challenged services. None reported reduction of inequalities as an explicit goal. Only seven made use of explicit patient and public involvement practices, and only six explicitly used published theories/models/frameworks to guide implementation. Programmes varied in their reporting of the planning, scope and design of evaluation, with weak designs evident., Conclusions: Poor transparency of reporting and weak or absent evaluation undermine large-scale improvement programmes by limiting learning and accountability.

Background: Implementation of national multiprofessional training for managing the obstetric emergency of impacted fetal head (IFH) at caesarean birth has potential to improve quality and safety in maternity care, but is currently lacking in the UK., Objectives: To evaluate a training package for managing IFH at caesarean birth with multiprofessional maternity teams., Methods: The training included an evidence-based lecture supported by an animated video showing management of IFH, followed by hands-on workshops and real-time simulations with use of a birth simulation trainer, augmented reality and management algorithms. Guided by the Kirkpatrick framework, we conducted a multimethod evaluation of the training with multiprofessional maternity teams. Participants rated post-training statements about relevance and helpfulness of the training and pre-training and post-training confidence in their knowledge and skills relating to IFH (7-point Likert scales, strongly disagree to strongly agree). An ethnographer recorded sociotechnical observations during the training. Participants provided feedback in post-training focus groups., Results: Participants (N=57) included 21 midwives, 25 obstetricians, 7 anaesthetists and 4 other professionals from five maternity units. Over 95% of participants agreed that the training was relevant and helpful for their clinical practice and improving outcomes following IFH. Confidence in technical and non-technical skills relating to managing IFH was variable before the training (5%-92% agreement with the pre-training statements), but improved in nearly all participants after the training (71%-100% agreement with the post-training statements). Participants and ethnographers reported that the training helped to: (i) better understand the complexity of IFH, (ii) recognise the need for multiprofessional training and management and (iii) optimise communication with those in labour and their birth partners., Conclusions: The evaluated training package can improve self-reported knowledge, skills and confidence of multiprofessional teams involved in management of IFH at caesarean birth. A larger-scale evaluation is required to validate these findings and establish how best to scale and implement the training., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Objective: To examine incidence of child marriage among displaced and host populations in humanitarian settings., Design: Cross-sectional surveys., Setting: Data were collected in Djibouti, Yemen, Lebanon and Iraq in the Middle East and in Bangladesh and Nepal in South Asia., Participants: Adolescent girls aged 10-19 in the six settings and age cohort comparators., Outcome Measures: Cumulative incidence of marriage by age 18., Results: In Bangladesh and Iraq, the hazard of child marriage did not differ between internally displaced populations (IDPs) and hosts (p value=0.25 and 0.081, respectively). In Yemen, IDPs had a higher hazard of child marriage compared with hosts (p value<0.001). In Djibouti, refugees had a lower hazard of child marriage compared with hosts (p value<0.001). In pooled data, the average hazard of child marriage was significantly higher among displaced compared with host populations (adjusted HR (aHR) 1.3; 95% CI 1.04 to 1.61).In age cohort comparisons, there was no significant difference between child marriage hazard across age cohorts in Bangladesh (p value=0.446), while in Lebanon and Nepal, younger cohorts were less likely to transition to child marriage compared with older comparators (p value<0.001). Only in Yemen were younger cohorts more likely to transition to child marriage, indicating an increase in child marriage rates after conflict (p value=0.034). Pooled data showed a downward trend, where younger age cohorts had, on average, a lower hazard of child marriage compared with older cohorts (aHR 0.36; 95% CI 0.29 to 0.4)., Conclusions: We did not find conclusive evidence that humanitarian crises are associated with universal increases in child marriage rates. Our findings indicate that decision-making about investments in child marriage prevention and response must be attuned to the local context and grounded in data on past and current trends in child marriage among communities impacted by crisis., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Coherent diffraction imaging (CDI) is a computational technique for reconstructing a complex-valued optical field from an intensity measurement. The approach is to illuminate an object with a coherent beam of light to form a diffraction pattern, and use a phase retrieval algorithm to reconstruct the object's complex transmittance from the measurement. However, as the name implies, conventional CDI assumes highly coherent illumination. Recent works therefore extend CDI to account for partial coherence and imperfect detection, by modeling light as an incoherent mixture of multiple fields (e.g., multiple wavelengths) and recovering each field simultaneously. In this work, we make strides towards the practical implementation and usage of multi-wavelength diffraction imaging. In particular, we provide novel analysis of the noise characteristics of multi-wavelength diffraction imaging, and show that it is preferable to coherent diffraction imaging under high signal-independent noise. Additionally, we present a compact coded diffraction imaging system and corresponding phase retrieval algorithms to robustly and simultaneously recover complex fields representing multiple wavelengths. Using a novel mixed-norm color prior, our prototype system reconstructs a larger number of multi-wavelength fields from fewer measurements than existing methods, and supports applications such as micron-scale optical path difference measurement via synthetic wavelength holography.

Background: The ripple effects of protracted armed conflicts include: significant gender-specific barriers to accessing essential services such as health, education, water and sanitation and broader macroeconomic challenges such as increased poverty rates, higher debt burdens, and deteriorating employment prospects. These factors influence the wider social and political determinants of health for women and a gendered analysis of the political economy of health in conflict may support strengthening health systems during conflict. This will in turn lead to equality and equity across not only health, but broader sectors and systems, that contribute to sustainable peace building., Methods: The methodology employed is a multidisciplinary narrative review of the published and grey literature on women and gender in the political economy of health in conflict., Results: The existing literature that contributes to the emerging area on the political economy of health in conflict has overlooked gender and specifically the role of women as a critical component. Gender analysis is incorporated into existing post-conflict health systems research, but this does not extend to countries actively affected by armed conflict and humanitarian crises. The analysis also tends to ignore the socially constructed patriarchal systems, power relations and gender norms that often lead to vastly different health system needs, experiences and health outcomes., Conclusions: Detailed case studies on the gendered political economy of health in countries impacted by complex protracted conflict will support efforts to improve health equity and understanding of gender relations that support health systems strengthening., (© 2021.

Research on the consequences of reproductive morbidity for women's lives and their economic and social roles is relatively under-developed. There is also a lack of consensus on appropriate conceptual frameworks to understand the social determinants of reproductive morbidity as well as their social and economic implications. We report here on an exploratory study in Yemen using quantitative (n=72 women) and qualitative methods (n=35 women), in 2005 and 2007 respectively, with women suffering from uterine prolapse, infertility or pelvic inflammatory disease (PID). It explored women's views on how reproductive morbidity affected their lives, marital security and their households, and the burden of paying for treatment. We also interviewed six health professionals about women's health care-seeking for these conditions. Sixty per cent of women reported that treatment was not affordable, and 43% had to sell assets or take out a loan to pay for care. Prolapse and PID interfered particularly in subsistence and household activities while infertility created social pressure. Reproductive morbidity is not a priority in Yemen, given its multiple public health needs and low resources, but by failing to provide comprehensive and affordable services for women, the country incurs developmental losses., (Copyright © 2012 Reproductive Health Matters.

Objective: To investigate the impact of socio-economic and environmental factors on developing severe malaria in comparison with mild malaria in Yemen., Method: Case-control study comparing 343 children aged 6 months to 10 years diagnosed with WHO-defined severe malaria (cases) at the main children's hospital in Taiz and 445 children with mild malaria (controls) diagnosed in the health centres, which serve the areas where the cases came from., Results: In univariate analysis, age <1 year, distance from health centre, delay to treatment and driving time to health centre were associated with progression from mild to severe malaria. In multivariate analysis, distance to nearest health centre >2 km was significantly associated with progression to severe disease. Environmental and vector control factors associated with protection from acquiring malaria (such as sleeping under bednets) were not associated with protection from moving from mild to severe disease., Conclusions: Innovative ways to improve access to antimalarial treatment for those living more then 2 km away from health centres such as home management of malaria, especially for infants and young children, should be explored in malaria-endemic areas of Yemen.

Notes of 4,000 obstetric and neo-natal cases have been analysed. The role of non-specific fetal infection (which means excluding syphilis, toxoplasmosis and German measles) has been defined with the backing of histopathological, bacteriological and clinical findings. Its role in perinatal mortality and neo-natal morbidity has been outlined. Possibilities for prevention of the condition are suggested, dealing with premature rupture of the membranes and clear-cut maternal infection. "At risk of infection" is the term that has been defined for neonates by studying carefully obstetrical clinical parameters where they are isolated or associated with other conditions but relatively innocuous. When the condition has been defined in particular cases, intensive supervision of the children at risk must be carried out so that as a result of bacteriological findings therapy can be started earlier, better adjusted to the condition and promising a better prognosis.

The different patterns of histiocytosis X are usually classified into three forms according to their clinical and pathological expression. One form is acute and disseminated ; the two others are chronic, unifocal or multifocal. Borderline cases and intermediate forms can be seen. For instance, onset can be acute or subacute in chronic disseminated forms, such as Hand-Schüller-Christian disease ; acute or subacute exacerbations may occur during the course of the disease. We report an observation of this type which is remarkable for three reasons. Fever was the initial manifestation and remained apparently isolated for one year. Subsequent osseous involvement was limited to the femur and tibia. Hypernatremia developed as a result of both diabetes insipidus and disrupted thirst control. These unusual features of our case-report led us to review previously published data.
