Exploring local knowledge and perceptions on zoonoses among pastoralists in northern and eastern Tanzania
Background: Zoonoses account for the most commonly reported emerging and re-emerging infectious diseases in Sub-Saharan Africa. However, there is limited knowledge on how pastoral communities perceive zoonoses in relation to their livelihoods, culture and their wider ecology. This study was carried out to explore local knowledge and perceptions on zoonoses among pastoralists in Tanzania. Methodology and principal findings: This study involved pastoralists in Ngorongoro district in northern Tanzania and Kibaha and Bagamoyo districts in eastern Tanzania. Qualitative methods of focus group discussions, participatory epidemiology and interviews were used. A total of 223 people were involved in the study. Among the pastoralists, there was no specific term in their local language that describes zoonosis. Pastoralists from northern Tanzania possessed a higher understanding on the existence of a number of zoonoses than their eastern districts' counterparts. Understanding of zoonoses could be categorized into two broad groups: a local syndromic framework, whereby specific symptoms of a particular illness in humans concurred with symptoms in animals, and the biomedical framework, where a case definition is supported by diagnostic tests. Some pastoralists understand the possibility of some infections that could cross over to humans from animals but harm from these are generally tolerated and are not considered as threats. A number of social and cultural practices aimed at maintaining specific cultural functions including social cohesion and rites of passage involve animal products, which present zoonotic risk. Conclusions: These findings show how zoonoses are locally understood, and how epidemiology and biomedicine are shaping pastoralists perceptions to zoonoses. Evidence is needed to understand better the true burden and impact of zoonoses in these communities. More studies are needed that seek to clarify the common understanding of zoonoses that could be used to guide effective and locally relevant interventions. Such studies should consider in their approaches the pastoralists' wider social, cultural and economic set up
The reporting on ERAS Compliance, Outcomes, and Elements Research (RECOvER) checklist: a joint statement by the ERASÂź and ERASÂź USA societies
Background: Enhanced Recovery After Surgery (ERAS) programs are multimodal care pathways designed to minimize the physiologic and psychological impact of surgery for patients. Increased compliance with ERAS guidelines is associated with improved patient outcomes across surgical types. As ERAS programs have proliferated, an unintentional effect has been significant variation in how ERAS-related studies are reported in the literature.
Methods: To improve the quality of ERAS reporting, the ERASÂź USA and the ERASÂź Society launched an effort to create an instrument to assist authors in manuscript preparation. Criteria to include were selected by a combination of literature review and expert opinion. The final checklist was refined by group consensus.
Results: The Societies present the Reporting on ERAS Compliance, Outcomes, and Elements Research (RECOvER) Checklist. The tool contains 20 items including best practices for reporting clinical pathways, compliance auditing, and formatting guidelines.
Conclusions: The RECOvER Checklist is intended to provide a standardized framework for the reporting of ERAS-related studies. The checklist can also assist reviewers in evaluating the quality of ERAS-related manuscripts. Authors are encouraged to include the RECOvER Checklist when submitting ERAS-related studies to peer-reviewed journals

The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe
The preponderance of matter over antimatter in the early Universe, the
dynamics of the supernova bursts that produced the heavy elements necessary for
life and whether protons eventually decay --- these mysteries at the forefront
of particle physics and astrophysics are key to understanding the early
evolution of our Universe, its current state and its eventual fate. The
Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed
plan for a world-class experiment dedicated to addressing these questions. LBNE
is conceived around three central components: (1) a new, high-intensity
neutrino source generated from a megawatt-class proton accelerator at Fermi
National Accelerator Laboratory, (2) a near neutrino detector just downstream
of the source, and (3) a massive liquid argon time-projection chamber deployed
as a far detector deep underground at the Sanford Underground Research
Facility. This facility, located at the site of the former Homestake Mine in
Lead, South Dakota, is approximately 1,300 km from the neutrino source at
Fermilab -- a distance (baseline) that delivers optimal sensitivity to neutrino
charge-parity symmetry violation and mass ordering effects. This ambitious yet
cost-effective design incorporates scalability and flexibility and can
accommodate a variety of upgrades and contributions. With its exceptional
combination of experimental configuration, technical capabilities, and
potential for transformative discoveries, LBNE promises to be a vital facility
for the field of particle physics worldwide, providing physicists from around
the globe with opportunities to collaborate in a twenty to thirty year program
of exciting science. In this document we provide a comprehensive overview of
LBNE's scientific objectives, its place in the landscape of neutrino physics
worldwide, the technologies it will incorporate and the capabilities it will
possess.Comment: Major update of previous version. This is the reference document for
LBNE science program and current status. Chapters 1, 3, and 9 provide a
comprehensive overview of LBNE's scientific objectives, its place in the
landscape of neutrino physics worldwide, the technologies it will incorporate
and the capabilities it will possess. 288 pages, 116 figure
Targeting HOX transcription factors in prostate cancer
YesBackground: The HOX genes are a family of transcription factors that help to determine cell and tissue identity
during early development, and which are also over-expressed in a number of malignancies where they have been
shown to promote cell proliferation and survival. The purpose of this study was to evaluate the expression of HOX
genes in prostate cancer and to establish whether prostate cancer cells are sensitive to killing by HXR9, an inhibitor
of HOX function.
Methods: HOX function was inhibited using the HXR9 peptide. HOX gene expression was assessed by RNA
extraction from cells or tissues followed by quantitative PCR, and siRNA was used to block the expression of the
HOX target gene, cFos. In vivo modelling involved a mouse flank tumour induced by inoculation with LNCaP cells.
Results: In this study we show that the expression of HOX genes in prostate tumours is greatly increased with
respect to normal prostate tissue. Targeting the interaction between HOX proteins and their PBX cofactor induces
apoptosis in the prostate cancer derived cell lines PC3, DU145 and LNCaP, through a mechanism that involves a
rapid increase in the expression of cFos, an oncogenic transcription factor. Furthermore, disrupting HOX/PBX
binding using the HXR9 antagonist blocks the growth of LNCaP tumours in a xenograft model over an extended
period.
Conclusion: Many HOX genes are highly over-expressed in prostate cancer, and prostate cancer cells are sensitive
to killing by HXR9 both in vitro and in vivo. The HOX genes are therefore a potential therapeutic target in prostate
cancer.The authors gratefully acknowledge the support of the Prostate Project charity (UK)
Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial
Background
Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy

Targeting the Creatine Kinase Pathway in EVI1-Positive Acute Myeloid Leukemia
Abnormal expression of the transcription factor EVI1 through chromosome 3q26 rearrangements has been implicated in the development of one of the most therapeutically challenging high-risk subtypes of acute myeloid leukemia (AML). Here we integrated genomic and metabolic screening of hematopoietic stem cells to reveal that EVI1 overexpression altered cellular metabolism. A pooled shRNA screen targeting metabolic enzymes identified the ATP-buffering, mitochondrial creatine kinase CKMT1 as a druggable dependency in EVI1-positive AML.
Of 18 screened AML cell lines harboring various genetic alterations, only the four EVI1-expressing lines exhibited markedly elevated CKMT1 protein expression and activity. Treatment of this cell line panel with either CKMT1-targeting shRNAs or cyclocreatine, an analog of the CKMT1 substrate creatine and inhibitor of the creatine biosynthesis pathway, showed that elevated CKMT1 protein expression correlated with sensitivity to CKMT1 pathway inhibition. Consistent with these data, flow cytometry analysis of a panel of 68 unselected primary AML patient specimens revealed that the four leukemias with the highest levels of EVI1 expression also had elevated CKMT1 protein levels and enhanced sensitivity to cyclocreatine treatment.
We next established that enforced EVI1 expression increased CKMT1 protein and mRNA levels and that three independent shRNA molecules targeting EVI1 drastically reduced CKMT1 expression in two EVI1-positive AML cell lines. A luciferase-based reporter system established that RUNX1 represses CKMT1 expression through direct binding to its promoter. ChIP-qPCR approaches were then applied to dissect the sequential events involved in EVI1-induced CKMT1 upregulation and the possible role of RUNX1 as an intermediate. In both primary AML samples and cell lines, we determined that EVI1 represses RUNX1 expression by directly binding to its promoter. This, in turn, eliminates repressive RUNX1 binding at the CKMT1 promoter and thereby promotes CKMT1 expression. Based on these data, we explored the relationship between EVI1 and RUNX1 expression with CKMT1 mRNA levels in two AML transcriptional datasets (GSE14468 and GSE10358). We divided these cohorts into four subgroups with high versus low expression of EVI1 and RUNX1. Consistent with our mechanistic analysis, primary AML samples within the EVI1high/RUNX1low subgroup were significantly more likely to express high levels of CKMT1 than AML samples in the other three subgroups.
CKMT1 promotes the metabolism of arginine to creatinine. To determine the effect of CKMT1 suppression on this pathway, we measured the metabolic flux of stable-isotope labeled L-arginine 13C6 through creatine synthesis using mass spectrometry. CKMT1-directed shRNAs or cyclocreatine selectively decreased intracellular phospho-creatine and blocked production of ATP by mitochondria. Salvage of the creatine pathway by exogenous phospho-creatine restored normal mitochondrial function, prevented the loss of viability of human EVI1-positive AML cells induced by cyclocreatine or CKMT1-directed shRNAs, and maintained the serial replating activity of Evi1-transformed bone marrow cells.
Primary human EVI1-positive AML is frequently associated with somatic NRAS mutations. Thus, to investigate whether EVI1 over-expression sensitizes primary AMLs to CKMT1 inhibition in vivo, we transplanted primary NrasG12D mutant AMLs with and without elevated Evi1 expression into congenic recipient mice. In this system, Ckmt1 knockdown did not significantly alter the outgrowth of control Nras mutant AML cells compared to a shControl (63% versus 71%). By contrast, NrasG12D AML cells characterized by elevated Evi1 expression were profoundly depleted by Ckmt1 suppression to 2% versus 58% in shControl recipients. Consistent with these results, pharmacologic or genetic inhibition of the CKMT1-dependent pathway blocked disease progression and prolonged the survival of mice injected with human EVI1-positive cells but not with EVI1-negative cells, without noticeable cytotoxic effect on normal murine cells.
In conclusion, we have integrated "omic" approaches to identify CKMT1 as a druggable liability in EVI-positive AML. This study supports a potential therapeutic avenue for targeting the creatine kinase pathway in EVI1-positive AML, which remains one of the worst outcome subtypes of AML
