The Creation of a Field Manual for Community Health Workers to Teach Child Health and Development During Home Visits: A Case Study of Participatory Content Creation.

Community health workers (CHWs) play a crucial role in improving child health and development in underserved populations. However, CHWs often face challenges in accessing appropriate guidance and materials for their home visits, hindering their ability to deliver accurate and relevant information to families. Extensive searches for existing resources were conducted to search for established field manual guidebooks for CHWs, however, no suitable material was found, highlighting the need for this case study. The exercise aimed to develop a comprehensive field manual guidebook and animated videos to support CHWs in the Amazon of Peru during their home visits. A multidisciplinary team of specialists was assembled to develop the material. The material development process employed a design thinking methodology, incorporating participatory content creation workshops with CHWs and experts in health topics relevant to the Amazon. This approach ensured cultural relevance and sensitivity in conveying information. The team created a list of 38 essential health and early childhood development messages for Amazonian communities. Infographics were designed for each topic, accompanied by easy-to-understand language and images to assist CHWs in conveying information effectively. To provide additional support, seven animated videos were created based on health behavior theory, covering topics such as anemia, healthy diet, diarrhea, breastfeeding, clean water, child-caregiver bond, and early childhood stimulation. The videos were designed for CHWs to share with caregivers during home visits, enhancing information transmission. The resulting guidebook, infographics, and animated videos were presented to CHWs in Loreto, Peru for feedback. Updated versions were printed and distributed to CHWs in seven communities in Loreto.

Deep Learning Reconstruction Enables Prospectively Accelerated Clinical Knee MRI.

Background MRI is a powerful diagnostic tool with a long acquisition time. Recently, deep learning (DL) methods have provided accelerated high-quality image reconstructions from undersampled data, but it is unclear if DL image reconstruction can be reliably translated to everyday clinical practice. Purpose To determine the diagnostic equivalence of prospectively accelerated DL-reconstructed knee MRI compared with conventional accelerated MRI for evaluating internal derangement of the knee in a clinical setting. Materials and Methods A DL reconstruction model was trained with images from 298 clinical 3-T knee examinations. In a prospective analysis, patients clinically referred for knee MRI underwent a conventional accelerated knee MRI protocol at 3 T followed by an accelerated DL protocol between January 2020 and February 2021. The equivalence of the DL reconstruction of the images relative to the conventional images for the detection of an abnormality was assessed in terms of interchangeability. Each examination was reviewed by six musculoskeletal radiologists. Analyses pertaining to the detection of meniscal or ligament tears and bone marrow or cartilage abnormalities were based on four-point ordinal scores for the likelihood of an abnormality. Additionally, the protocols were compared with use of four-point ordinal scores for each aspect of image quality: overall image quality, presence of artifacts, sharpness, and signal-to-noise ratio. Results A total of 170 participants (mean age ± SD, 45 years ± 16; 76 men) were evaluated. The DL-reconstructed images were determined to be of diagnostic equivalence with the conventional images for detection of abnormalities. The overall image quality score, averaged over six readers, was significantly better (P < .001) for the DL than for the conventional images. Conclusion In a clinical setting, deep learning reconstruction enabled a nearly twofold reduction in scan time for a knee MRI and was diagnostically equivalent with the conventional protocol. © RSNA, 2023 Supplemental material is available for this article.

Stigma toward psychosis in urban Chile: Engaging "what matters most" to resist stigma through recovery-oriented services.

OBJECTIVE: Stigma jeopardizes recovery and successful implementation of mental health services (MHS) globally. Despite cultural variation in how stigma manifests, few studies have examined how culture fundamentally impacts the concept of "personhood" in Latin America. Chile has expanded MHS, providing universal coverage for evaluation and treatment of first episode psychosis (FEP). We applied the "what matters most" (WMM) framework of stigma to identify culturally salient factors that shape or protect against stigma in urban Chile, identifying potential implications for MHS and recovery. METHODS: In-depth interviews (n = 48) were conducted with MHS users with psychotic disorders (n = 18), their family members (n = 15), and community members (n = 15), from two urban regions in Chile. Interviews were coded and analyzed to identify WMM, how WMM shapes stigma, and how MHS can influence achieving WMM. RESULTS: Traditional values emphasizing physical/social appearance, gender roles, family, and social connectedness are highly valued. Socioeconomic transitions have engendered capitalistic variations on traditional values, with increasing emphasis on professional careers for men and women, individualism, and independence. Psychotic disorders interfere with fulfillment of both traditional and capitalist values, thereby reinforcing stigma. However, MHS are seen as partially effective in enabling fulfillment of some goals, including employment, appearance, and independence, while often remaining insufficient in enabling capacity to achieve marriage and having a family. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: MHS that facilitate recovery by engaging users in services, such as pharmacotherapy, education/vocational rehabilitation, and family-centered care aligned with cultural values can mitigate stigma and facilitate recovery by enabling users to fulfill WMM.

Repeatability of simultaneous 3D 1H MRF/23Na MRI in brain at 7 T.

Proton MRI can provide detailed morphological images, but it reveals little information about cell homeostasis. On the other hand, sodium MRI can provide metabolic information but cannot resolve fine structures. The complementary nature of proton and sodium MRI raises the prospect of their combined use in a single experiment. In this work, we assessed the repeatability of normalized proton density (PD), T1, T2, and normalized sodium density-weighted quantification measured with simultaneous 3D 1H MRF/23Na MRI in the brain at 7 T, from ten healthy volunteers who were scanned three times each. The coefficients of variation (CV) and the intra-class correlation (ICC) were calculated for the mean and standard deviation (SD) of these 4 parameters in grey matter, white matter, and cerebrospinal fluid. As result, the CVs were lower than 3.3% for the mean values and lower than 6.9% for the SD values. The ICCs were higher than 0.61 in all 24 measurements. We conclude that the measurements of normalized PD, T1, T2, and normalized sodium density-weighted from simultaneous 3D 1H MRF/23Na MRI in the brain at 7 T showed high repeatability. We estimate that changes > 6.6% (> 2 CVs) in mean values of both 1H and 23Na metrics could be detectable with this method.

Assessing Perceptions of Broad Consent Concerning Biological Specimen Collection in a Cohort of Young Sexual Minority Men.

The use of broad consent to store human biospecimens to be used in future research studies has increased over the years. However, it is currently unknown how young sexual minority men (YSMM) perceive broad consent in these specific types of studies. Therefore, in this study we aimed to determine the extent to which YSMM are comfortable with providing broad consent concerning their identifiable biological specimens to a variety of entities, including external researchers and pharmaceutical companies and to examine the relationship between mistrust based on racial/ethnic identity or sexual orientation and attitudes toward broad consent. YSMM (N = 239) ages 24-27 years were recruited from a prospective cohort study in New York City in 2018 to complete a survey assessing attitudes about the use of broad consent concerning biospecimens for secondary research. We found that YSMM were most willing to provide broad consent to the researcher from the study they were enrolled in (85.3%), other researchers within the same university (82.4%), and researchers at other universities (74.5%). Participants were least willing to provide broad consent to government organizations (64.4%) and pharmaceutical companies (53.8%). Further, we found that medical mistrust based on racial/ethnic identity or sexual orientation was associated with attitudes toward the use of broad consent. Research institutions should consider modifying consent procedures around the use of broad consent in order to maximize recruitment and retention, especially among minority populations.

Dietary intake, intestinal infection, and safe drinking water among children with anemia in Peru: a cross-sectional analysis.

BACKGROUND: Anemia is a major public health concern that is present in 41.7% of children under 5 worldwide. The prevalence of anemia in Peru was 43.6% in 2017, a decrease by only 6.8% in 8 years. Despite great efforts made by the government to reduce anemia by distributing free multi-micronutrient supplements and promote the consumption of iron rich foods, progress has been slow. The current study sought to better understand why the prevalence remains high by analyzing the dietary intake, incidence of intestinal infectious disease, and access to safe drinking water by children with anemia in Peru. METHODS: A cross-sectional analysis was conducted using data from two national surveys that were combined by child ID. Descriptive statistics was analyzed to understand the experience of children with anemia in comparison to child without anemia. Logistic multivariate regression analyses were conducted to test the associations between anemia and dietary intake, intestinal infection, and access to safe drinking water. RESULTS: The sample included 586 children between 6 and 35 months. The prevalence of anemia in this population was 53%. The portion of children that consumed sufficient iron to meet the recommendation for their age was 62%. Of the children with anemia, 52% consumed sufficient iron to meet their recommendation, vs. 72% of children without anemia (p < 0.001). The children with anemia were more likely to have an intestinal infection during the previous year (35% vs. 26%, p = 0.057) and less likely to have access to safe drinking water (77% vs. 86%, p = 0.002) than those without anemia. The logistic analysis revealed that having an intestinal infection increased the odds of having anemia (OR = 1.64, CI 95% [1.041-2.584]), and having access to safe drinking waters decreased the odds of having anemia (OR = 0.578, [0.334-0.998]). CONCLUSIONS: More than half of the children with anemia in Peru already consume sufficient iron to meet their daily requirement. However, they continue to have anemia, likely due to intestinal infection, such as diarrhea and parasites, from a lack of access to safe drinking water and hygienic practices.
