OBJECTIVES The aim of this population-based, retrospective study was to analyze biological and clinical features and treatment results in children diagnosed with MPAL in all Polish pediatric oncology centers between 2007 and 2018. METHODS Among 2,893 children and adolescents diagnosed and treated for acute leukemia, 39 (1.35%) patients fulfilled the WHO criteria of MPAL. The T/myeloid phenotype was most prevalent. RESULTS Cytogenetics findings were seen in 2 (5.1%), while chromosomal abnormalities were found in 14 (35.9%) patients. Thirty-two patients achieved CR-1, including 23 (92.0%) treated with ALL-directed chemotherapy and 9 (64.3%) treated with AML-type induction regimens. Within these patients, 4 (12.5%) died due to treatment-related complications and 11 (34.4%) relapsed. Nineteen (63.3%) patients underwent allo-HSCT in CR-1 and 14 (73.7%) of them have been in CR-1. In total, 17 (43.6%) patients remain in CR-1 for 1 - 12 years, including 14 (58.3%) with T/myeloid MPAL. The 5-year pOS and pEFS were 51.8% and 44.2%, respectively. The overall survival for ALL-directed therapy was significantly better than the one for AML-type chemotherapy (p=0.001). It was also better for patients who underwent HSCT in CR-1 (p=0.001). CONCLUSIONS The prognosis of MPAL is unsatisfactory, but initial treatment with ALL-directed chemotherapy consolidated with allo-HSCT improves the outcomes in MPAL.

Feelings like when you woke up in bed at night as a kid, and saw a dark shadow in the corner, and wondered if it was going to get you. If you're like me, in recent days you've also experienced awe at so many triumphs over such fear, individual and collective - our 65 year old ED clerk showing up to their shift, through great anxiety, or healthcare providers boarding buses heading into the teeth of the Wuhan epidemic. The pages of AEM this month provide further examples of such triumphs, of individuals in a time and place of great stress overcoming the impulse to curl up and focus on themselves, and instead expanding beyond themselves to help others. This is the finest tradition of humanity and medicine, and all of these efforts at service through science inspire and give heart. This article is protected by copyright.

BACKGROUND When an infant is born extremely preterm, there is a long rocky road for the mother if she wants to breastfeed. Some manage to reach their goals, others do not. Studies of feeding extremely preterm infants in the neonatal intensive care unit (NICU) are scarce. DESIGN A qualitative method with an inductive approach. METHODS Nine mothers giving birth to extremely preterm infants were interviewed by telephone after discharge from the NICU. The interviews were transcribed verbatim and analysed with qualitative content analysis. The COREQ checklist was followed. Findings The overall theme was "you can't flight, you need to fight". The theme reflects the mothers will to do the best for their infants even if the struggle with milk expression and breastfeeding practice evoked feelings of helplessness, exposure, worry, and disappointment. The categories forming the theme were The wish to provide own breastmilk; For the infant's best; Loss of control; Help to reach the goals. CONCLUSION The mothers had a strong will to provide breastmilk to their infants but requested more support in order to be successful. RELEVANCE TO CLINICAL PRACTICE There is a need for evidence based support programs for mothers of extremely preterm infants to encourage them to persevere with milk expression and breastfeeding over time.

Yet, despite their immense filtering capacities, marine sponges appear to be less affected by elevated nutrients than sympatric benthic organisms, such as corals. While the molecular-level stress response of sponges to elevated seawater temperatures and other toxicants has been defined, this study represents the first global gene expression analysis of how sponges respond to elevated nitrogen. Gene correlation network analysis revealed that sponge gene modules, coded by colors, became either highly upregulated (Blue) or downregulated (Turquoise, Black, Brown) as nitrogen treatment levels increased. GO enrichment analysis of the different modules revealed genes involved in cell signaling, immune response and flagella motility were affected by increasing nitrogen levels. Notably, a decrease in the regulation of NF-kappaB signalling and an increase in protein degradation was identified, which is comparable to metabolic pathways associated with the sponge thermal stress response.

Climate suitability is characterized using ecological niche models (ENMs), which correlate species occurrence data with current environmental covariates and project future distributions using the modeled relationships together with climate predictions. Despite their widespread adoption, ENMs rely on several assumptions that are rarely validated in situ and can be highly sensitive to modeling decisions, precluding their reliability in conservation decision-making. Using data from a novel, large-scale community science program, we developed dynamic occupancy models to validate near-term climate suitability projections for bluebirds and nuthatches in summer and winter. We estimated occupancy, colonization, and extinction dynamics across species' ranges in the United States in relation to projected climate suitability in the 2020s, and used a Gibbs variable selection approach to quantify evidence of species-climate relationships.
