RESUMEN
Mali national policy recommends that women take iron and folic acid supplements (IFA) from the time of the first antenatal care (ANC) visit, throughout pregnancy and during the first 3 months after delivery. In 2020, the World Health Organization (WHO) updated their ANC guidelines to recommend the United Nations International Multiple Micronutrient Antenatal Preparation (UNIMMAP) formulation of multiple micronutrient supplements (MMS) in the context of rigorous research, including implementation research. In Bamako, Mali, a codesign process was used to tailor antenatal care MMS packaging and counselling materials aimed at optimizing delivery and uptake of and adherence to MMS. This paper presents the codesign process along with the results of a post-intervention qualitative assessment to evaluate the behaviour change intervention. At the conclusion of the intervention, we conducted semistructured qualitative interviews with 24 women who had received the intervention and six pharmacy managers from the six health centres participating in the study. We conducted two focus groups with midwives who had delivered the intervention and two group discussions with family members of women who had received the intervention. Respondent perspectives reveal an easy experience transitioning from previously used IFA. Women and providers concur that the intervention counselling materials and visual aids were instrumental in influencing the perceived benefit and uptake of MMS. Family members play an influential role in pregnant women's decision-making regarding MMS uptake. MMS and the associated implementation strategies developed through the codesign process were found to be a highly acceptable intervention.
RESUMEN
Shared decision-making (SDM) is the standard of care for patient or surrogates and their clinicians to arrive at a medical decision. Evidence suggests that SDM increases patients' understanding of their illness and satisfaction with their decision-making process. Dialysis patients often report the perception that they were passive participants in the decision to start dialysis, suggesting further opportunities for enhancing the application of SDM in decision-making with patients with kidney disease. The hallmark feature of SDM is sensitive, culturally- and equity-informed communication and effective partnership between patient or surrogate and clinician. In the process, the patient's personal expertise in the realm of their values and priorities is elicited, and the clinician's medical expertise is shared. The integration of this shared expertise then leads to an informed treatment decision. Frameworks such as the Serious Illness Conversation Guide and REMAP are guides for the SDM process, and communication tools and mnemonics can help facilitate SDM conversations. This paper will address SDM in nephrology practice, reviewing underlying supportive evidence, context, and timing for employing SDM in the trajectory of chronic kidney disease and acute kidney injury, special considerations in vulnerable populations to promote health equity, and communication tools and frameworks to facilitate the SDM process. By learning and applying these frameworks and tools, nephrology providers will be able to employ SDM in the management of kidney disease.

Current methods for measuring intervention coverage for reproductive, maternal, newborn, and child health and nutrition (RMNCH+N) do not adequately capture the quality of services delivered. Without information on the quality of care, it is difficult to assess whether services provided will result in expected health improvements. We propose a six-step coverage framework, starting from a target population to (1) service contact, (2) likelihood of services, (3) crude coverage, (4) quality-adjusted coverage, (5) user-adherence-adjusted coverage and (6) outcome-adjusted coverage. We support our framework with a comprehensive review of published literature on effective coverage for RMNCH+N interventions since 2000. We screened 8103 articles and selected 36 from which we summarised current methods for measuring effective coverage and computed the gaps between 'crude' coverage measures and quality-adjusted measures. Our review showed considerable variability in data sources, indicator definitions and analytical approaches for effective coverage measurement. Large gaps between crude coverage and quality-adjusted coverage levels were evident, ranging from an average of 10 to 38 percentage points across the RMNCH+N interventions assessed. We define effective coverage as the proportion of individuals experiencing health gains from a service among those who need the service, and distinguish this from other indicators along a coverage cascade that make quality adjustments. We propose a systematic approach for analysis along six steps in the cascade. Research to date shows substantial drops in effective delivery of care across these steps, but variation in methods limits comparability of the results. Advancement in coverage measurement will require standardisation of effective coverage terminology and improvements in data collection and methodological approaches.
RESUMEN
Rhodopsin (rh1) is the visual pigment expressed in rod photoreceptors of vertebrates that is responsible for initiating the critical first step of dim-light vision. Rhodopsin is usually a single copy gene; however, we previously discovered a novel rhodopsin-like gene expressed in the zebrafish retina, rh1-2, which we identified as a functional photosensitive pigment that binds 11-cis retinal and activates in response to light. Here, we localized expression of rh1-2 in the zebrafish retina to a subset of peripheral photoreceptor cells, which indicates a partially overlapping expression pattern with rh1 We also expressed, purified and characterized Rh1-2, including investigation of the stability of the biologically active intermediate. Using fluorescence spectroscopy, we found the half-life of the rate of retinal release of Rh1-2 following photoactivation to be more similar to that of the visual pigment rhodopsin than to the non-visual pigment exo-rhodopsin (exorh), which releases retinal around 5 times faster. Phylogenetic and molecular evolutionary analyses show that rh1-2 has ancient origins within teleost fishes, is under similar selective pressure to rh1, and likely experienced a burst of positive selection following its duplication and divergence from rh1 These findings indicate that rh1-2 is another functional visual rhodopsin gene, which contradicts the prevailing notion that visual rhodopsin is primarily found as a single copy gene within ray-finned fishes. The reasons for retention of this duplicate gene, as well as possible functional consequences for the visual system, are discussed.

PURPOSE: The intent of this study was to explore the relation between language variation and theory of mind (ToM) in African American child narrators. METHOD: Fifty children produced a narrative on the basis of the wordless book, Frog, Where Are You? ToM was assessed by children's internal-state words and false-belief mentioning in the book's narratives as well as their performance on the Reading the Eyes in the Mind Test (Baron-Cohen, Joliffe, Mortimore, & Robertson, 1997). Correlation and linear regression analyses were performed to determine the relationship between narrative language ability and ToM indices. Relationships between language variation, ToM indices, and socioeconomic status were also explored. RESULTS: There was no correlation between language variation and the 3 ToM indicators. False-belief mentioning accounted for the most variance in children's narrative language. Language variation scores and ToM performance were both unrelated to children's socioeconomic backgrounds. CONCLUSION: ToM indicators, such as false-belief mentioning, provide information about African American children's narrative ability and appear to be dialect-neutral.

Shoppers make many food choices while buying groceries. Children frequently accompany caregivers, giving them the potential to influence these choices. We aimed to understand low-income shoppers' perceptions of how children influence caregivers' purchasing decisions and how the supermarket environment could be manipulated to allow children to serve as change agents for healthy food purchasing in a primarily African-American community. We conducted thirty in-depth interviews, five follow-up interviews, one supermarket walk-through interview, and four focus groups with adult supermarket shoppers who were regular caregivers for children under age 16. We conducted one focus group with supermarket employees and one in-depth interview with a supermarket manager. Qualitative data were analyzed using iterative thematic coding and memo writing. Caregivers approached grocery shopping with efforts to save money, prevent waste and purchase healthy food for their families, but described children as promoting unplanned, unhealthy food purchases. This influence was exacerbated by the supermarket environment, which participants found to promote unhealthy options and provide limited opportunities for children to interact with healthier foods. Caregivers' suggestions for promoting healthy purchasing for shoppers with children included manipulating the placement of healthy and unhealthy foods and offering opportunities for children to taste and interact with healthy options.

The organizer is essential for dorsal-ventral (DV) patterning in vertebrates. Goosecoid (Gsc), a transcriptional repressor found in the organizer, elicits partial secondary axes when expressed ventrally in Xenopus, similar to an organizer transplant. Although gsc is expressed in all vertebrate organizers examined, knockout studies in mouse suggested that it is not required for DV patterning. Moreover, experiments in Xenopus and zebrafish suggest a role in head formation, although a function in axial mesoderm formation is less clear. To clarify the role of Gsc in vertebrate development, we used gain- and loss-of-function approaches in zebrafish. Ventral injection of low doses of gsc produced incomplete secondary axes, which we propose results from short-range repression of BMP signaling. Higher gsc doses resulted in complete secondary axes and long-range signaling, correlating with repression of BMP and Wnt signals. In striking contrast to Xenopus, the BMP inhibitor Chordin (Chd) is not required for Gsc function. Gsc produced complete secondary axes in chd null mutant embryos and gsc-morpholino knockdown in chd mutants enhanced the mutant phenotype, suggesting that Gsc has Chd-independent functions in DV patterning. Even more striking was that Gsc elicited complete secondary axes in the absence of three secreted BMP antagonists, Chd, Follistatin-like 1b and Noggin 1, suggesting that Gsc functions in parallel with secreted BMP inhibitors. Our findings suggest that Gsc has dose dependent effects on axis induction and provide new insights into molecularly distinct short- and long-range signaling activities of the organizer.

The T-box gene eomesodermin (eomes) has been implicated in mesoderm specification and patterning in both zebrafish and frog. Here, we describe an additional function for eomes in the control of morphogenesis. Epiboly, the spreading and thinning of an epithelial cell sheet, is a central component of gastrulation in many species; however, despite its importance, little is known about its molecular control. Here, we show that repression of eomes function in the zebrafish embryo dramatically inhibits epiboly movements. We also show that eomes regulates the expression of a zygotic homeobox transcription factor mtx2. Gene knockdown of mtx2 using antisense morpholino oligonucleotides, likewise, leads to an inhibition of epiboly; moreover, we show that knockdown of mtx2 function in the extraembryonic yolk syncytial layer only is sufficient to cause epiboly defects. Thus, we have identified two components in a molecular pathway controlling epiboly and show that interactions between deep layer cells of the embryo proper and extraembryonic tissues contribute in a coordinated manner to different aspects of epiboly movements.
