Genomic Prediction with Pedigree and Genotype x Environment Interaction in Spring Wheat Grown in South and West Asia, North Africa, and Mexico

Developing genomic selection (GS) models is an important step in applying GS to accelerate the rate of genetic gain in grain yield in plant breeding. In this study, seven genomic prediction models under two cross-validation (CV) scenarios were tested on 287 advanced elite spring wheat lines phenotyped for grain yield (GY), thousand-grain weight (GW), grain number (GN), and thermal time for flowering (TTF) in 18 international environments (year-location combinations) in major wheat-producing countries in 2010 and 2011. Prediction models with genomic and pedigree information included main effects and interaction with environments. Two random CV schemes were applied to predict a subset of lines that were not observed in any of the 18 environments (CV1), and a subset of lines that were not observed in a set of the environments, but were observed in other environments (CV2). Genomic prediction models, including genotype x environment (GxE) interaction, had the highest average prediction ability under the CV1 scenario for GY (0.31), GN (0.32), GW (0.45), and TTF (0.27). For CV2, the average prediction ability of the model including the interaction terms was generally high for GY (0.38), GN (0.43), GW (0.63), and TTF (0.53). Wheat lines in siteyear combinations in Mexico and India had relatively high prediction ability for GY and GW. Results indicated that prediction ability of lines not observed in certain environments could be relatively high for genomic selection when predicting GxE interaction in multi-environment trials

Regional collaboration for the development of national childhood cancer plans in Latin America and the Caribbean

This article aims to describe the activities conducted by the National Childhood Cancer Plan Working Group to support the development of national childhood cancer plans in Latin America and the Caribbean in the period 2019–2022, and to present the stage of plan development. The Working Group activities were supported by the Pan American Health Organization and St. Jude Children’s Research Hospital, which is the World Health Organization (WHO) Collaborating Centre for Childhood Cancer. Year after year, the workshops and activities developed with the Working Group mobilized key stakeholders: pediatric oncologists, representatives of the Ministry of Health, foundations supporting childhood cancer initiatives, and hospital administrators. As of February 2023, one regional framework is in place, approved by the Council of Ministries of Health of Central America and the Dominican Republic, nine countries are currently implementing national plans or laws that include childhood cancer, and ten countries are writing new plans. The WHO three-step framework helped to guide the Working Group activities. All plans were supported by a situational analysis, which highlighted the importance of having systematized data for evidence-based policies. To increase implementation success, an accompanying budget and timeline help to ensure the adequate implementation of the interventions. More than anything, committed stakeholders remain the most fundamental element to successfully write and approve a national childhood cancer plan. This is an opportunity to share these countries’ experience so the strategy can be adapted to support other countries developing a childhood cancer plan and extended to other public health areas

Advances in the Global Initiative for Childhood Cancer: implementation in Latin America and the Caribbean

This report describes the status of childhood cancer control initiatives in Latin America and the Caribbean (LAC). Progress between 2017 and 2023 is measured using the outcome indicators from the Pan American Health Organization (PAHO) childhood cancer logic model aligned with the World Health Organization Global Initiative for Childhood Cancer (GICC). This report also describes the advances, barriers, and facilitators for the implementation of the GICC at the Regional level. Methods used in this report encompassed a comprehensive approach, incorporating a literature review, interviews, surveys, and a Delphi study developed by the technical team of the PAHO Non-Communicable Diseases and Mental Health Department and by the GICC LAC working group. Since 2017, there has been a substantial increase in the number of countries that have included childhood cancer in their national regulations. Currently, 21 LAC countries are involved in the GICC implementation, activities, and dialogues. However, the objectives for 2030 will only be achieved if Member States overcome the barriers to accelerating the pace of initiative implementation. There is an urgent need to increase the efforts in childhood cancer control in LAC, especially regarding the prioritization of timely detection, essential diagnostics, access to cancer treatment, palliative care, and close follow-up of children and adolescents with cancer

Strengthening public health policies for childhood cancer: Peru’s achievements through the WHO Global Initiative for Childhood Cancer

Objective. To report the progress in Peru, since June 2019, in the implementation of the World Health Organization Global Initiative for Childhood Cancer using the CureAll framework, which can be replicated in low- and middle-income countries. Methods. A mixed method was used of participatory and documentary evaluation. The participatory evaluation included stakeholders from various government institutions, nonprofit organizations, and international partners. The documentary aspect consisted of a review of data on the regulatory environment, national projects, and interventions implemented. The Ministry of Health engaged more than 150 participants to form working committees, which have developed policy and regulatory documents to strengthen care services. Results. Achievements include a decrease in the national treatment abandonment rate from 18.6% to 8.5%, the approval of the Childhood Cancer Law, improvements in the management of patients with febrile neutropenia, and a reduction in rates of events of clinical deterioration and mortality of hospitalized patients. The Cure All implementation framework allows local teams to implement specific strategies and monitor early outcomes in pediatric oncology. Conclusions. The results obtained reflect the teamwork, the leadership of the authorities, the technical support of professionals, and the support of involved organizations. Further actions will be needed to guarantee sustainability, and monitoring tools are needed to assure success in the planned activities

American college of rheumatology provisional criteria for clinically relevant improvement in children and adolescents with childhood-onset systemic Lupus erythematosus

To develop a Childhood Lupus Improvement Index (CHILI) as a tool to measure response to therapy in childhood-onset systemic lupus erythematosus (cSLE), with a focus on clinically relevant improvement (CRIcSLE). Methods Pediatric nephrology and rheumatology subspecialists (n = 213) experienced in cSLE management were invited to define CRIcSLE and rate a total of 433 unique patient profiles for the presence/absence of CRIcSLE. Patient profiles included the following cSLE core response variables (CRVs): global assessment of patient well-being (patient-global), physician assessment of cSLE activity (MD-global), disease activity index score (here, we used the Systemic Lupus Erythematosus Disease Activity Index), urine protein-to-creatinine ratio, and Child Health Questionnaire physical summary score. Percentage and absolute changes in these cSLE-CRVs (baseline versus follow-up) were considered in order to develop candidate algorithms and validate their performance (sensitivity, specificity, area under the receiver operating characteristic curve [AUC]; range 0-1). Results During an international consensus conference, unanimous agreement on a definition of CRIcSLE was achieved; cSLE experts (n = 13) concurred (100%) that the preferred CHILI algorithm considers absolute changes in the cSLE-CRVs. After transformation to a range of 0-100, a CHILI score of >= 54 had outstanding accuracy for identifying CRIcSLE (AUC 0.93, sensitivity 81.1%, and specificity 84.2%). CHILI scores also reflect minor, moderate, and major improvement for values exceeding 15, 68, and 92, respectively (all AUC >= 0.92, sensitivity >= 93.1%, and specificity >= 73.4%). Conclusion The CHILI is a new, seemingly highly accurate index for measuring CRI in cSLE over time. This index is useful to categorize the degree of response to therapy in children and adolescents with cSLE.715579590CNPQ - Conselho Nacional de Desenvolvimento Científico e TecnológicoFAPESP – Fundação de Amparo à Pesquisa Do Estado De São Paulo303422/2015-7; 7/2016-9; 304255/2015-7215/03756-

Geoeconomic variations in epidemiology, ventilation management, and outcomes in invasively ventilated intensive care unit patients without acute respiratory distress syndrome: a pooled analysis of four observational studies

Background: Geoeconomic variations in epidemiology, the practice of ventilation, and outcome in invasively ventilated intensive care unit (ICU) patients without acute respiratory distress syndrome (ARDS) remain unexplored. In this analysis we aim to address these gaps using individual patient data of four large observational studies. Methods: In this pooled analysis we harmonised individual patient data from the ERICC, LUNG SAFE, PRoVENT, and PRoVENT-iMiC prospective observational studies, which were conducted from June, 2011, to December, 2018, in 534 ICUs in 54 countries. We used the 2016 World Bank classification to define two geoeconomic regions: middle-income countries (MICs) and high-income countries (HICs). ARDS was defined according to the Berlin criteria. Descriptive statistics were used to compare patients in MICs versus HICs. The primary outcome was the use of low tidal volume ventilation (LTVV) for the first 3 days of mechanical ventilation. Secondary outcomes were key ventilation parameters (tidal volume size, positive end-expiratory pressure, fraction of inspired oxygen, peak pressure, plateau pressure, driving pressure, and respiratory rate), patient characteristics, the risk for and actual development of acute respiratory distress syndrome after the first day of ventilation, duration of ventilation, ICU length of stay, and ICU mortality. Findings: Of the 7608 patients included in the original studies, this analysis included 3852 patients without ARDS, of whom 2345 were from MICs and 1507 were from HICs. Patients in MICs were younger, shorter and with a slightly lower body-mass index, more often had diabetes and active cancer, but less often chronic obstructive pulmonary disease and heart failure than patients from HICs. Sequential organ failure assessment scores were similar in MICs and HICs. Use of LTVV in MICs and HICs was comparable (42·4% vs 44·2%; absolute difference -1·69 [-9·58 to 6·11] p=0·67; data available in 3174 [82%] of 3852 patients). The median applied positive end expiratory pressure was lower in MICs than in HICs (5 [IQR 5-8] vs 6 [5-8] cm H2O; p=0·0011). ICU mortality was higher in MICs than in HICs (30·5% vs 19·9%; p=0·0004; adjusted effect 16·41% [95% CI 9·52-23·52]; p<0·0001) and was inversely associated with gross domestic product (adjusted odds ratio for a US$10 000 increase per capita 0·80 [95% CI 0·75-0·86]; p<0·0001). Interpretation: Despite similar disease severity and ventilation management, ICU mortality in patients without ARDS is higher in MICs than in HICs, with a strong association with country-level economic status
