Abstract
BACKGROUND Endothelial cells (ECs) are a critical component of the hematopoietic niche, and the cross-talk between ECs and leukemia was reported recently. This study aimed to determine the genes involved in the proliferation inhibition of endothelial cells in leukemia. METHODS Human umbilical vein endothelial cells (HUVEC) were cultured alone or co-cultured with K562 cell lines. GeneChip assays were performed to identify the differentially expressed genes. The Celigo, MTT assay, and flow cytometric analysis were used to determine the effect of RNAi DIDO on cell growth and apoptosis. The differently expressed genes were verified by qRT-PCR (quantitative real-time PCR) and western-blot. RESULTS In K562-HUVEC co-cultured cell lines, 323 down-regulated probes were identified and the extracellular signal-regulated kinase 5 (ERK5) signaling pathway was significantly inhibited. Among the down-regulated genes, the death inducer-obliterator gene (DIDO) is a part of the centrosome protein and may be involved in cell mitosis. As shown in the public data, leukemia patients with lower expression of DIDO showed a better overall survival (OS). The HUVEC cells were infected with shDIDO lentivirus, and reduced expression, inhibited proliferation, and increased apoptosis was observed in shDIDO cells. In addition, the expression of Cyclin-Dependent Kinase 6 (CDK6) and Cyclin D1 (CCND1) genes was inhibited in shDIDO cells. Finally, the public ChIP-seq data were used to analyze the regulators that bind with DIDO, and the H3K4me3 and PolII (RNA polymerase II) signals were found near the Exon1 and exon2 sites of DIDO. CONCLUSION The knock-down of DIDO will inhibit the proliferation of endothelial cells in the leukemia environment. The expression of DIDO may be regulated by H3K4me3 and the inhibition of DIDO may lead to the down-regulation of CDK6 and CCND1. However, how DIDO interacts with CDK6 and CCND1 requires further study.

Abstract
BACKGROUND Stroke patients with large vessel occlusion (LVO) require endovascular therapy (EVT) provided by comprehensive stroke centers (CSC). One strategy to achieve fast stroke symptom 'onset to treatment' times (OTT) is the preclinical selection of patients with severe stroke for direct transport to CSC. Another is the optimization of interhospital transfer workflow. Our aim was to investigate the dynamics of the OTT of 'drip-and-ship' patients as well as the current 'door-in-door-out' time (DIDO) and its determinants at representative regional German stroke units. METHODS We determined the numbers of all EVT treatments, 'drip-and-ship' and 'direct-to-center' patients and their median OTT from the mandatory quality assurance registry of the federal state of Hesse, Germany (2012-2019). Additionally, we captured process time stamps from primary stroke centers (PSC) in a consecutive registry of patients referred for EVT in our regional stroke network over a 3 months period. RESULTS Along with an increase of the EVT rate, the proportion of drip-and-ship patients grew steadily from 19.4% in 2012 to 31.3% in 2019. The time discrepancy for the median OTT between 'drip-and-ship' and 'direct-to-center' patients continuously declined from 173 to 74 min. The largest share of the DIDO (median 92, IQR 69-110) is spent with the organization of EVT and consecutive patient transfer. CONCLUSIONS 'Drip-and-ship' patients are an important and growing proportion of stroke patients undergoing EVT. The discrepancy in OTT for EVT between 'drip-and-ship' and 'direct-to-center' patients has been reduced considerably. Further optimization of the DIDO primarily aiming at the processes after the detection of LVO is urgently needed to improve stroke patient care.

Abstract
BACKGROUND Australia's mineral, resource and infrastructure sectors continues to expand as operations in rural and remote locations increasingly rely on fly-in, fly-out or drive-in, drive-out workforces in order to become economically competitive. The issues in effectively managing these workforces are becoming more apparent with reported high amounts of turnover and concerns for safety and performance. The issues presented include a range of physical, mental, psychosocial, safety and community challenges. OBJECTIVES This review aims to consolidate a range of research conducted to communicate potential challenges for industry in relation to a wide variety of issues when engaging and using FIFO/DIDO workforces which includes compressed working schedule design (work schedules), working hours, fatigue, safety performance, employee wellbeing, turnover, psychosocial relationships and community concerns. METHODS A comprehensive literature review was performed using EBSCOhost, PubMed and google scholar, with a focus on FIFO or DIDO workforces engaged within the resources sector. Search terms were kept broad in order to capture all national and international research conducted and included: "fly-in, fly-out" "FIFO" "DIDO" "drive-in, drive-out" "mining". There was no date restriction included in the search. RESULTS Many of the studies were focused on sleep quality, fatigue and the influence of lowered safety performance while at work, presenting an increased risk for health and safety. These issues may be exacerbated for the FIFO workforce when linked to additional research surrounding the extended periods of absence from families influencing workers personal relationships, psychological wellbeing, job satisfaction and the reported high amounts of turnover within the industry. Taken together, this presents a unique implication for the management and continued use of FIFO workforces when considering balancing safety and performance with economic viability of production and operations. CONCLUSIONS The issues of long working hours, fatigue, turnover and job satisfaction are not new to the management of workers. However, FIFO workforces appear to be at an increased risk physically and mentally due to a culmination of other influences, such as extended and frequent periods of absence from friends and families which contribute to feelings of isolation and lowered psychological wellbeing. FIFO workers and their families, engage in a unique lifestyle, rarely are other workers subjected to long hours and compressed work weeks while separated or isolated from their families for extended periods of time. Recently, FIFO interest has shifted to understanding the influences on employee engagement, satisfaction, retention and safety. Considering the management of FIFO workforces from a holistic perspective incorporating all of the issues impacting on these workers may assist to ensure the challenges associated with FIFO employment are understood, addressed and communicated to workers and their families is crucial for safety and health.

Abstract
Chronic Myeloid Leukemia (CML), Polycythemia Vera (PV), Essential Thrombocythemia (ET) and Primary Myelofibrosis (PMF) are Myeloproliferative Neoplasms (MPN) characterized by clonal myeloproliferation without cell maturation impairment. CML pathogenesis is associated with the Ph chromosome leading to BCR-ABL tyrosine-kinase constitutive expression. The Ph negative MPN (PV, ET and PMF) are characterized by the mutation JAK2(V617F) of the JAK2 protein in the auto-inhibitory JH2 domain, which is found in most PV patients and in approximately half of ET and PMF patients. Considerable effort is being made to understand the role of JAK2(V617F) at the MPN initiation and to clarify the pathogenesis and apoptosis resistance in CML, PV, ET and PMF patients. In the present investigation, we evaluated the Death Inducer-Obliterator (DIDO) (variants DIDO 1, 2 and 3) levels in CML, PV, ET and PMF patients. Our data reported the DIDO 1, 2 and 3 differential expressions in Myeloproliferative Neoplasms.

Abstract
We examined if there is truth to the preconceptions that non-resident workers (including FIFO/DIDO's) detract from communities. We used marine debris to test this, specifically focussing on littering behaviour and evidence of awareness of local environmental programs that focus on marine debris. Littering was most common at recreational areas, then beaches and whilst boating. Twenty-five percent of respondents that admit to littering, reported no associated guilt with their actions. Younger respondents litter more frequently. Thus, non-resident workers litter at the same rate as permanent residents, visitors and tourists in this region, within this study. Few respondents are aware of the environmental programs that operate in their local region. Awareness was influenced by a respondent's residency (non-residents are less aware), age, and level of education. To address this failure we recommend that industries, that use non-resident workers, should develop inductions that expose new workers to the environmental programs in their region.
