RESUMEN
Experimental citizen science offers new ways to organize on-farm testing of crop varieties and other agronomic options. Its implementation at scale requires software that streamlines the process of experimental design, data collection and analysis, so that different organizations can support trials. This article considers ClimMob software developed to facilitate implementing experimental citizen science in agriculture. We describe the software design process, including our initial design choices, the architecture and functionality of ClimMob, and the methodology used for incorporating user feedback. Initial design choices were guided by the need to shape a workflow that is feasible for farmers and relevant for farmers, breeders and other decision-makers. Workflow and software concepts were developed concurrently. The resulting approach supported by ClimMob is triadic comparisons of technology options (tricot), which allows farmers to make simple comparisons between crop varieties or other agricultural technologies tested on farms. The software was built using Component-Based Software Engineering (CBSE), to allow for a flexible, modular design of software that is easy to maintain. Source is open-source and built on existing components that generally have a broad user community, to ensure their continuity in the future. Key components include Open Data Kit, ODK Tools, PyUtilib Component Architecture. The design of experiments and data analysis is done through R packages, which are all available on CRAN. Constant user feedback and short communication lines between the development teams and users was crucial in the development process. Development will continue to further improve user experience, expand data collection methods and media channels, ensure integration with other systems, and to further improve the support for data-driven decision-making.
RESUMEN
Matching crop varieties to their target use context and user preferences is a challenge faced by many plant breeding programs serving smallholder agriculture. Numerous participatory approaches proposed by CGIAR and other research teams over the last four decades have attempted to capture farmers' priorities/preferences and crop variety field performance in representative growing environments through experimental trials with higher external validity. Yet none have overcome the challenges of scalability, data validity and reliability, and difficulties in capturing socio-economic and environmental heterogeneity. Building on the strengths of these attempts, we developed a new data-generation approach, called triadic comparison of technology options (tricot). Tricot is a decentralized experimental approach supported by crowdsourced citizen science. In this article, we review the development, validation, and evolution of the tricot approach, through our own research results and reviewing the literature in which tricot approaches have been successfully applied. The first results indicated that tricot-aggregated farmer-led assessments contained information with adequate validity and that reliability could be achieved with a large sample. Costs were lower than current participatory approaches. Scaling the tricot approach into a large on-farm testing network successfully registered specific climatic effects of crop variety performance in representative growing environments. Tricot's recent application in plant breeding networks in relation to decision-making has (i) advanced plant breeding lines recognizing socio-economic heterogeneity, and (ii) identified consumers' preferences and market demands, generating alternative breeding design priorities. We review lessons learned from tricot applications that have enabled a large scaling effort, which should lead to stronger decision-making in crop improvement and increased use of improved varieties in smallholder agriculture.
RESUMEN
Aggregates of misfolded α-synuclein proteins (asyn) are key markers of Parkinson's disease. Asyn proteins have three domains: an N-terminal domain, a hydrophobic NAC core implicated in aggregation, and a proline-rich C-terminal domain. Proteins with truncated C-terminal domains are known to be prone to aggregation and suggest that studying domain-domain interactions in asyn monomers could help elucidate the role of the flanking domains in modulating protein structure. To this end, we used Gaussian accelerated molecular dynamics (GAMD) to simulate wild-type (WT), N-terminal truncated (DN), C-terminal truncated (ΔC), and isolated NAC domain variants (isoNAC). Using clustering and contact analysis, we found that N- and C-terminal domains interact via electrostatic interactions, while the NAC and N-terminal domains interact through hydrophobic contacts. Our work also suggests that the C-terminal domain does not interact directly with the NAC domain but instead interacts with the N-terminal domain. Removal of the N-terminal domain led to increased contacts between NAC and C-terminal domains and the formation of interdomain ß-sheets. Removal of either flanking domain also resulted in increased compactness of every domain. We also found that the contacts between flanking domains results in an electrostatic potential (ESP) that could possibly lead to favorable interactions with anionic lipid membranes. Removal of the C-terminal domain disrupts the ESP in a way that is likely to over-stabilize protein-membrane interactions. All of this suggests that one of the roles of the flanking domains may be to modulate the protein structure in a way that helps maintain elongation, hide hydrophobic residue from the solvent, and maintain an ESP that aids favorable interactions with the membrane.
RESUMEN
Objectives: More and more disasters are occurring and there will be an increasing shortage of physicians in the future. Telemedicine could be a solution here to offer medical care despite the lack of physicians in the area of operation. This study analyzes whether telemedicine for lower-qualified paramedics is comparable to conventional disaster medicine. Methods: A simulation study was conducted in which one conventional and two telemedicine groups cared for thermal-traumatically injured in a stressful situation. The telemedicine was conducted on tablets with integrated vital sign monitoring or on smartphones. The physician engagement time, the number of physician contacts, the time for relevant measures and the usage behavior of telemedicine were examined between these groups. Results: One telemedicine group showed significantly fewer patient contacts. This can be attributed to the ongoing consultation in the intervention group with more contacts. There are no significant differences in the relevant measures. Conclusion: Telemedicine is comparable to conventional disaster medicine in civil protection. Due to potential technical failures, it should primarily be used to compensate for the lack of physicians, and training should focus on an exit-strategy in case of a failure of the telemedicine.
RESUMEN
BACKGROUND: While Malawi has made great strides increasing the number of facility-based births, maternal and neonatal mortality remains high. An intervention started in 2019 provided short-course training followed by year-long longitudinal bedside mentorship for nurse midwives at seven health facilities in Blantyre district. The intervention was initiated following invitation from the district to improve outcomes for patients during childbirth. This study examined the impact of the intervention on the reporting of obstetric and neonatal complications and related care. METHODS: Patient level data were collected from the District Health Information System 2 database from intervention and non-intervention facilities. Bivariate analysis explored the impact of longitudinal bedside mentorship on select District Health Information System 2 variables at six-month intervals. Outcomes were then analyzed using nonlinear quantile mixed models to better account for the impact of time and clustering at the facility level. RESULTS: Significant changes were found in the reporting of obstetric and neonatal complications over time at intervention facilities compared to non-intervention facilities. Intervention facilities showed statistically significant increases in the reporting of prolonged labor, pre/eclampsia, fetal distress, retained placenta, and premature labor. There was also a statistically significant decrease in the reporting of no complications in the multivariate model (95%CI: -0.8 to -0.2). In both the bivariate and multivariate models, the reporting of 'None' significantly decreased (0.8â¯% median), while the reporting of prematurity (0.2â¯% median) and asphyxia (0.3â¯% median) both significantly increased. The missingness of data at intervention facilities decreased to almost zero compared to non-intervention facilities. DISCUSSION: The increase in reported maternal and neonatal complications suggests improved early identification of complications at the facility level. The improved accuracy of patient data from intervention facilities shows the impact mentorship has on data quality which is crucial for the allocation of resources. By highlighting the apparent dose-response relationship of longitudinal bedside mentorship, this study will inform the broader use of mentorship in training programs. Future research is needed to explore the impact of longitudinal mentorship on quality of care.
RESUMEN
Fibromyalgia syndrome (FMS) is a common chronic pain disorder and often occurs as a concomitant disease in rheumatological diseases. Managing FMS takes a complex approach and often involves various non-pharmacological therapies. Fasting interventions have not been in the focus of research until recently, but preliminary data have shown effects on short- and medium-term pain as well as on physical and psychosomatic outcomes in different chronic pain disorders. This single-arm observational study investigated the effects of prolonged fasting (3-12 days, <600 kcal/d) embedded in a multimodal treatment setting on inpatients with FMS. Patients who were treated at the Department of Internal Medicine and Nature-Based Therapies of the Immanuel Hospital Berlin, Germany, between 02/2018 and 12/2020 answered questionnaires at hospital admission (V0) and discharge (V1), and then again three (V2), six (V3), and 12 (V4) months later. Selected routine blood and anthropometric parameters were also assessed during the inpatient stay. A total of 176 patients with FMS were included in the study. The Fibromyalgia Impact Questionnaire (FIQ) total score dropped by 13.7 ± 13.9 (p < 0.001) by V1, suggesting an improvement in subjective disease impact. Pain (NRS: reduction by 1.1 ± 2.5 in V1, p < 0.001) and quality of life (WHO-5: +4.9 ± 12.3 in V1, p < 0.001) improved, with a sustainable effect across follow-up visits. In contrast, mindfulness (MAAS: +0.3 ± 0.7 in V1, p < 0.001), anxiety (HADS-A: reduction by 2.9 ± 3.5 in V1, p < 0.0001), and depression (HADS-D: reduction by 2.7 ± 3.0 in V1, p < 0.0001) improved during inpatient treatment, without longer-lasting effects thereafter. During the study period, no serious adverse events were reported. The results suggest that patients with FMS can profit from a prolonged therapeutic fasting intervention integrated into a complex multimodal inpatient treatment in terms of quality of life, pain, and disease-specific functional parameters.

BACKGROUND: Interstitial lung disease (ILD) is the most common cause of death in systemic sclerosis. To date, the progression of systemic sclerosis-associated ILD is judged by the accrual of lung damage on CT and pulmonary function tests. However, diagnostic tools to assess disease activity are not available. Here, we tested the hypothesis that quantification of fibroblast activation by PET-CT using a 68Ga-labelled selective inhibitor of prolyl endopeptidase FAP (68Ga-FAPI-04) would correlate with ILD activity and disease progression in patients with systemic sclerosis-associated ILD. METHODS: Between Sept 10, 2018, and April 8, 2020, 21 patients with systemic sclerosis-associated ILD confirmed by high-resolution CT (HRCT) within 12 months of inclusion and with onset of systemic sclerosis-associated ILD within 5 years or signs of progressive ILD and 21 controls without ILD were consecutively enrolled. All participants underwent 68Ga-FAPI-04 PET-CT imaging and standard-of-care procedures, including HRCT and pulmonary function tests at baseline. Patients with systemic sclerosis-associated ILD were followed for 6 months with HRCT and pulmonary function tests. We compared baseline 68Ga-FAPI-04 PET-CT uptake with standard diagnostic tools and predictors of ILD progression. The association of 68Ga-FAPI-04 uptake with changes in forced vital capacity was analysed using mixed-effects models. Follow-up 68Ga-FAPI-04 PET-CT scans were obtained in a subset of patients treated with nintedanib (follow-up between 6-10 months) to assess change over time. FINDINGS: 68Ga-FAPI-04 accumulated in fibrotic areas of the lungs in patients with systemic sclerosis-associated ILD compared with controls, with a median standardised uptake value (SUV) mean over the whole lung of 0·80 (IQR 0·60-2·10) in the systemic sclerosis-ILD group and 0·50 (0·40-0·50) in the control group (p<0·0001) and a mean whole lung maximal SUV of 4·40 (range 3·05-5·20) in the systemic sclerosis-ILD group compared with 0·70 (0·65-0·70) in the control group (p<0·0001). Whole-lung FAPI metabolic active volume (wlFAPI-MAV) and whole-lung total lesion FAPI (wlTL-FAPI) were not measurable in control participants, because no 68Ga-FAPI-04 uptake above background level was observed. In the systemic sclerosis-ILD group the median wlFAPI-MAV was 254·00 cm3 (IQR 163·40-442·30), and the median wlTL-FAPI was 183·60 cm3 (98·04-960·70). 68Ga-FAPI-04 uptake was higher in patients with extensive disease, with previous ILD progression, or high EUSTAR activity scores than in those with with limited disease, previously stable ILD, or low EUSTAR activity scores. Increased 68Ga-FAPI-04 uptake at baseline was associated with progression of ILD independently of extent of involvement on HRCT scan and the forced vital capacity at baseline. In consecutive 68Ga-FAPI-04 PET-CTs, changes in 68Ga-FAPI-04 uptake was concordant with the observed response to the fibroblast-targeting antifibrotic drug nintedanib. INTERPRETATION: Our study presents the first in-human evidence that fibroblast activation correlates with fibrotic activity and disease progression in the lungs of patients with systemic sclerosis-associated ILD and that 68Ga-FAPI-04 PET-CT might improve risk assessment of systemic sclerosis-associated ILD.

RESUMEN
Cada vez más se hace indispensable poner en funcionamiento los llamados procesos de educación permanente que faciliten el acceso continuo a la educación, se ajusten a los cambios políticos y progresos tecnológicos, se adapten a las situaciones coyunturales y alcancen una cobertura total de la población que va a capacitarse. Dentro de este planteo las instituciones deben poner en práctica metodologías educacionales novedosas que permitan la posibilidad de reducir costos y ampliar la cobertura. Una de esas metodologías es la educación a distancia. En el presente artículo se analiza este tipo de educación, que aplica métodos y técnicas de trabajo individual y en equipo (estudios a través de materiales escritos y audiovisuales que, junto con tutorías de apoyo y equipos e instrumentos prácticos conforman un paquete instructivo) y actividades presenciales, dirigidas o supervisadas; ofrece a la vez la posibilidad de un horario de estudio complementario a la jornada de trabajo. Facilita asimismo los procesos de educación permanente de recursos humanos en servicio; los impulsa a adquirir una mayor responsabilidad en su propia formación a favor de su desarrollo integral y de la excelencia en la prestación de servicios. Es una opción para la formación de recursos humanos dedicados a favorecer la prestación de servicios de salud, y su introducción en los actuales procesos educacionales debe ser paulatina y progresiva. El Programa de Adiestramiento en Salud para Centro América y Panamá (PASCAP) está proponiendo una guía metodológica para el diseño de sistemas de educación a distancia como un marco de referencia que debe ser adaptado a las características y necesidades concretas de cada país e institución en particular. A grandes rasgos las etapas son: marco conceptual; procesos de planificación académica, de producción académica, de enseñanza-aprendizaje y de evaluación
