In pursuit of a better world: crop improvement and the CGIAR.

The CGIAR crop improvement (CI) programs, unlike commercial CI programs, which are mainly geared to profit though meeting farmers' needs, are charged with meeting multiple objectives with target populations that include both farmers and the community at large. We compiled the opinions from >30 experts in the private and public sector on key strategies, methodologies, and activities that could the help CGIAR meet the challenges of providing farmers with improved varieties while simultaneously meeting the goals of: (i) nutrition, health, and food security; (ii) poverty reduction, livelihoods, and jobs; (iii) gender equality, youth, and inclusion; (iv) climate adaptation and mitigation; and (v) environmental health and biodiversity. We review the crop improvement processes starting with crop choice, moving through to breeding objectives, production of potential new varieties, selection, and finally adoption by farmers. The importance of multidisciplinary teams working towards common objectives is stressed as a key factor to success. The role of the distinct disciplines, actors, and their interactions throughout the process from crop choice through to adoption by farmers is discussed and illustrated.

Transition From Targeted Breeding to Mainstreaming of Biofortification Traits in Crop Improvement Programs.

Biofortification breeding for three important micronutrients for human health, namely, iron (Fe), zinc (Zn), and provitamin A (PVA), has gained momentum in recent years. HarvestPlus, along with its global consortium partners, enhances Fe, Zn, and PVA in staple crops. The strategic and applied research by HarvestPlus is driven by product-based impact pathway that integrates crop breeding, nutrition research, impact assessment, advocacy, and communication to implement country-specific crop delivery plans. Targeted breeding has resulted in 393 biofortified crop varieties by the end of 2020, which have been released or are in testing in 63 countries, potentially benefitting more than 48 million people. Nevertheless, to reach more than a billion people by 2030, future breeding lines that are being distributed by Consultative Group on International Agricultural Research (CGIAR) centers and submitted by National Agricultural Research System (NARS) to varietal release committees should be biofortified. It is envisaged that the mainstreaming of biofortification traits will be driven by high-throughput micronutrient phenotyping, genomic selection coupled with speed breeding for accelerating genetic gains. It is noteworthy that targeted breeding gradually leads to mainstreaming, as the latter capitalizes on the progress made in the former. Efficacy studies have revealed the nutritional significance of Fe, Zn, and PVA biofortified varieties over non-biofortified ones. Mainstreaming will ensure the integration of biofortified traits into competitive varieties and hybrids developed by private and public sectors. The mainstreaming strategy has just been initiated in select CGIAR centers, namely, International Maize and Wheat Improvement Center (CIMMYT), International Rice Research Institute (IRRI), International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), International Institute of Tropical Agriculture (IITA), and International Center for Tropical Agriculture (CIAT). This review will present the key successes of targeted breeding and its relevance to the mainstreaming approaches to achieve scaling of biofortification to billions sustainably.

Afectación articular en adolescente con artritis idiopática juvenil / Joint involvement in an adolescent with juvenile idiopathic arthritis

La artritis idiopática juvenil es una enfermedad inflamatoria sistémica y crónica que se caracteriza por el daño articular y la presencia de manifestaciones extraarticulares que afectan distintos órganos y sistemas de órganos del cuerpo humano. Como enfermedad tiene varias formas clínicas de presentación que se corresponden con posibles enfermedades en la edad adulta. El objetivo de la presente investigación es presentar el caso de un adolescente de 14 años de edad con historia de cuadro inflamatorio poliarticular de más de 3 años de duración con deformidad articular en ambas rodillas, lo cual es poco frecuente y que es expresión del proceso inflamatorio mantenido. Después del tratamiento fue dado de alta con una mejoría notable de los rangos de movimiento articular. En la actualidad evoluciona satisfactoriamente y lleva alrededor de un año en seguimiento en consulta externa sin exacerbaciones de la actividad clínica de la enfermedad. Se considera importante el reporte del caso para concientizar a la comunidad médica en relación con el diagnóstico precoz de esta enfermedad para minimizar el riesgo de aparición de complicaciones articulares y sistémicas(AU)

Juvenile idiopathic arthritis is a systemic and chronic inflammatory disease characterized by joint involvement and the presence of extra-articular manifestations that occur in different organs and organ systems of the human body. As a disease, it includes a series of clinical forms of presentation that correspond to possible diseases in adulthood. The objective of this research is to present the case of a 14-year-old adolescent with a history of polyarticular inflammatory symptoms lasting more than three years with the presence of rare joint deformity in both knees, which is an expression of the sustained inflammatory process. The case report is considered important to raise awareness in the medical community regarding the early diagnosis of this disease to minimize the risk of the appearance of joint and systemic complications(AU)
