    Global climate change has broad-ranging impacts on the natural environment and human civilization. Increasing average temperatures along with more frequent heat waves collectively have negative effects on cultivated crops in agricultural sectors and wild species in natural ecosystems. These aberrantly hot temperatures, together with cold stress, represent major abiotic stresses to plants. Molecular and physiological responses to high and low temperatures are intricately linked to the regulation of important plant hormones. In this review, we shall highlight our current understanding of how changing temperatures regulate plant hormone pathways during immunity, stress responses and development. This article will present an overview of known temperature-sensitive or temperature-reinforced molecular hubs in hormone biosynthesis, homeostasis, signaling and downstream responses. These include recent advances on temperature regulation at the genomic, transcriptional, post-transcriptional and post-translational levels – directly linking some plant hormone pathways to known thermosensing mechanisms. Where applicable, diverse plant species and various temperature ranges will be presented, along with emerging principles and themes. It is anticipated that a grand unifying synthesis of current and future fundamental outlooks on how fluctuating temperatures regulate important plant hormone signaling pathways can be leveraged towards forward-thinking solutions to develop climate-smart crops amidst our dynamically changing world

    Modalidad de Seminario de Graduación como forma de culminación de estudios tiene como propósito la adquisición de conocimientos, el desarrollo de habilidades y la formación de hábitos necesarios para el profesional que demanda el desarrollo del país. En el año 2009, como una respuesta a la problemática que atrasaba la carrera Educación comercial en la que había dificultad para llenar los cincuenta cupos correspondientes a la matricula de cada año, se propuso en la asignatura de Seminario de Graduación el análisis de esta problemática mediante los temas: “Factores que inciden en la Oferta Educativa y la Demanda Estudiantil “, “Plan de Captación”, “Perfil de salida de los Egresados” y su “Situación Laboral”. Dando continuidad a esta situación en el año 2011 se propone como uno de los temas de investigación en la modalidad de Seminario de Graduación “Sistematización de los trabajos de Graduación de la Carrera Educación Comercial del año 2009”, con el objetivo de valorar el cumplimiento de la normativa para esta modalidad de culminación de estudios, la correcta aplicación del diseño metodológico y la articulación horizontal y vertical que los informes finales deben presentar. Una vez analizado el instrumento diseñado para llevar a cabo el presente estudio, para llevar a cabo el presente estudio hemos llegado a la conclusión de que efectivamente existe una marcada sistematización en los informes presentados en el año 2009, la cual se evidencia en la interrelación que tienen los temas Oferta Educativa y Demanda Estudiantil, Plan de Captación de Estudiantes, Perfil de salida de los Egresados en Educación Comercial e Inserción Laboral de los graduados (articulación horizontal), así como la secuencia en el tiempo que tienen estos elementos (articulación vertical)

    Mapping disparities in education across low- and middle-income countries

    Analyses of the proportions of individuals who have completed key levels of schooling across all low- and middle-income countries from 2000 to 2017 reveal inequalities across countries as well as within populations. Educational attainment is an important social determinant of maternal, newborn, and child health(1-3). As a tool for promoting gender equity, it has gained increasing traction in popular media, international aid strategies, and global agenda-setting(4-6). The global health agenda is increasingly focused on evidence of precision public health, which illustrates the subnational distribution of disease and illness(7,8); however, an agenda focused on future equity must integrate comparable evidence on the distribution of social determinants of health(9-11). Here we expand on the available precision SDG evidence by estimating the subnational distribution of educational attainment, including the proportions of individuals who have completed key levels of schooling, across all low- and middle-income countries from 2000 to 2017. Previous analyses have focused on geographical disparities in average attainment across Africa or for specific countries, but-to our knowledge-no analysis has examined the subnational proportions of individuals who completed specific levels of education across all low- and middle-income countries(12-14). By geolocating subnational data for more than 184 million person-years across 528 data sources, we precisely identify inequalities across geography as well as within populations.Peer reviewe

    Since 2000, many countries have achieved considerable success in improving child survival, but localized progress remains unclear. To inform efforts towards United Nations Sustainable Development Goal 3.2—to end preventable child deaths by 2030—we need consistently estimated data at the subnational level regarding child mortality rates and trends. Here we quantified, for the period 2000–2017, the subnational variation in mortality rates and number of deaths of neonates, infants and children under 5 years of age within 99 low- and middle-income countries using a geostatistical survival model. We estimated that 32% of children under 5 in these countries lived in districts that had attained rates of 25 or fewer child deaths per 1,000 live births by 2017, and that 58% of child deaths between 2000 and 2017 in these countries could have been averted in the absence of geographical inequality. This study enables the identification of high-mortality clusters, patterns of progress and geographical inequalities to inform appropriate investments and implementations that will help to improve the health of all populations

    Mapping local patterns of childhood overweight and wasting in low- and middle-income countries between 2000 and 2017

    A double burden of malnutrition occurs when individuals, household members or communities experience both undernutrition and overweight. Here, we show geospatial estimates of overweight and wasting prevalence among children under 5 years of age in 105 low- and middle-income countries (LMICs) from 2000 to 2017 and aggregate these to policy-relevant administrative units. Wasting decreased overall across LMICs between 2000 and 2017, from 8.4% (62.3 (55.1–70.8) million) to 6.4% (58.3 (47.6–70.7) million), but is predicted to remain above the World Health Organization’s Global Nutrition Target of <5% in over half of LMICs by 2025. Prevalence of overweight increased from 5.2% (30 (22.8–38.5) million) in 2000 to 6.0% (55.5 (44.8–67.9) million) children aged under 5 years in 2017. Areas most affected by double burden of malnutrition were located in Indonesia, Thailand, southeastern China, Botswana, Cameroon and central Nigeria. Our estimates provide a new perspective to researchers, policy makers and public health agencies in their efforts to address this global childhood syndemic

    Co-creating an arts-based eye health education strategy in Zanzibar: process, outcomes and lessons learnt

    INTRODUCTION: Published examples of health programme co-creation are scarce and we found none in the field of eye care. We described the outcomes and lessons learnt from the ZANZIbar Arts for Children’s Eyesight (ZANZI-ACE) eye health programme co-creation process. METHODS: We used a 2.5-day stakeholder workshop (number of participants=34) to develop the ZANZI-ACE intervention, which aimed to use music performances in eye health education to improve child eye health service uptake in Zanzibar. A Zanzibar-wide music competition was then launched to encourage local participation, followed by a judging session to select three pieces as the ZANZI-ACE eye health programme intervention materials. RESULTS: The barriers to the improved uptake of child eye health services raised by the participants were mainly cultural and social. Sensitising parents, teachers, children and community members with proper eye health knowledge was the key to addressing these barriers. The goal of sensitisation is to improve children’s vision so that they can achieve their fullest potential. Music and song ranked highest among the proposed art forms, so three music pieces were chosen as the ZANZI-ACE eye health programme intervention materials. A detailed ZANZI-ACE implementation strategy, a theory of change and key performance outcomes indicators were developed. CONCLUSION: The co-creation process and outcomes of the ZANZI-ACE eye health programme show that engaging a diverse group of stakeholders is critical to developing locally relevant health programmes. The lessons learnt from the process will prove useful to researchers who aspire to design innovative health programmes
