Natural killer cell-mediated cytotoxicity shapes the clonal evolution of B cell leukaemia.

The term cancer immunoediting describes the dual role by which the immune system can suppress and promote tumour growth and is divided into three phases: elimination, equilibrium and escape. The role of NK cells has mainly been attributed to the elimination phase. Here we show that NK cells play a role in all three phases of cancer immunoediting.

Mindfulness-Based Interventions in Schools: Assessing the Evidence Base.

Objective: Mindfulness-based interventions are increasingly being used in schools to improve students' mental, emotional, and behavioral development. Although many mindfulness programs exist, the types of programs that are effective for specific age groups remain unclear. In this systematic review, the authors used established rating criteria to describe the level of evidence for school-based mindfulness interventions.

Social and Emotional Learning Interventions for Preadolescents and Adolescents: Assessing the Evidence Base.

Objective: The social and emotional learning (SEL) framework is widely recognized as being effective for developing social and emotional competencies among students of all ages. However, the evidence for specific intervention models with older student populations is less established. The objective of this systematic review was to rate the evidence supporting the effectiveness of SEL interventions aimed at improving mental health outcomes among preadolescents and adolescents.

Reasons for Discharge in a National Network of Early Psychosis Intervention Programs.

Background: Discharge from early psychosis intervention is a critical stage of treatment that may occur for a variety of reasons. This study characterizes reasons for discharge among participants in early psychosis intervention programs participating in the Early Psychosis Intervention Network (EPINET) which comprises >100 programs in the United States organized under 8 academic hubs.

Study Design: We analyzed 1787 discharges, focusing on program completion, unilateral termination by the client/family, and lost contact with the client/family.

Antibullying Interventions in Schools: Assessing the Evidence Base.

Objective: This systematic review used established rating criteria to describe the level of evidence for interventions aimed at preventing or reducing bullying perpetration and victimization in schools, synthesized the evidence for students from racially and ethnically diverse backgrounds, and reviewed the literature for available information to conduct an economic analysis of the interventions.

Methods: Major databases, gray literature, and evidence-base registries were searched to identify studies published from 2008 through 2022. The authors rated antibullying intervention models as having high, moderate, or low evidence depending on the number and rigor of studies with positive findings.

Breast cancer remotely imposes a myeloid bias on haematopoietic stem cells by reprogramming the bone marrow niche.

Myeloid cell infiltration of solid tumours generally associates with poor patient prognosis and disease severity. Therefore, understanding the regulation of myeloid cell differentiation during cancer is crucial to counteract their pro-tumourigenic role. Bone marrow (BM) haematopoiesis is a tightly regulated process for the production of all immune cells in accordance to tissue needs.

The impact of religion on changes in end-of-life practices in European intensive care units: a comparative analysis over 16 years.

Purpose: Religious beliefs affect end-of-life practices in intensive care units (ICUs). Changes over time in end-of-life practices were not investigated regarding religions.

Methods: Twenty-two European ICUs (3 regions: Northern, Central, and Southern Europe) participated in both Ethicus-1 (years 1999-2000) and Ethicus-2 studies (years 2015-2016).

Deficits in cerebellum-dependent learning and cerebellar morphology in male and female BTBR autism model mice.

Recently, there has been increased interest in the role of the cerebellum in autism spectrum disorders (ASD). To better understand the pathophysiological role of the cerebellum in ASD, it is necessary to have a variety of mouse models that have face validity for cerebellar disruption in humans. Here, we add to the literature on the cerebellum transgenic and induced mouse models of autism with the characterization of the cerebellum in the BTBR T+Itpr3/J (BTBR) inbred mouse strain, which has behavioral phenotypes that are suggestive of ASD in patients.

DRAG in situ barcoding reveals an increased number of HSPCs contributing to myelopoiesis with age.

Ageing is associated with changes in the cellular composition of the immune system. During ageing, hematopoietic stem and progenitor cells (HSPCs) that produce immune cells are thought to decline in their regenerative capacity. However, HSPC function has been mostly assessed using transplantation assays, and it remains unclear how HSPCs age in the native bone marrow niche.

CellDestiny: A RShiny application for the visualization and analysis of single-cell lineage tracing data.

Single-cell lineage tracing permits the labeling of individual cells with a heritable marker to follow the fate of each cell's progeny. Over the last twenty years, several single-cell lineage tracing methods have emerged, enabling major discoveries in developmental biology, oncology and gene therapies. Analytical tools are needed to draw meaningful conclusions from lineage tracing measurements, which are characterized by high variability, sparsity and technical noise.

Effects on Motor Performance in Dystonia-A Kinematic Study.

Background: The kinematic effects of have not previously been studied. The mechanism(s) by which these sensory tricks modify dystonic movement is not well understood.

Objectives: A kinematic investigation of the phenomenon in patients with dystonia.

Increased Knowledge of Adult-Onset Dystonia Amongst Medical Students via Brief Video Education: A Systematic Review and Cohort Study.

Most doctors have limited knowledge of dystonia, a movement disorder that can affect people of all ages; this contributes to diagnostic delay and poor quality of life. We investigated whether a brief educational intervention could improve knowledge of dystonia amongst medical students. We conducted a systematic review on undergraduate knowledge of dystonia and created an eight-minute video on the condition.

Global Comparison of Communication of End-of-Life Decisions in the ICU.

Background: Prolonging life in the ICU increasingly is possible, so decisions to limit life-sustaining therapies frequently are made and communicated to patients and families or surrogates. Little is known about worldwide communication practices and influencing factors.

Research Question: Are there regional differences in end-of-life communication practices in ICUs worldwide?

Study Design And Methods: This analysis of data from a prospective, international study specifically addressed end-of-life communications in consecutive patients who died or had limitation of life-sustaining therapy over 6 months in 199 ICUs in 36 countries, grouped regionally.

Co-worker relationships and their impact on nurses in Irish public healthcare settings.

This article presents the findings of a secondary analysis of data arising from a quantitative study of 3769 nurses on co-worker relationships and their impact on nurses working in public healthcare settings in Ireland. The overall findings from this analysis suggest moderate to high levels of satisfaction with co-worker relationships, with an average scale mean of 77%. Statistically significant lower scale means were identified in respect of nurses whose basic nursing qualification was awarded in a country outside the EU, among students and among those working in the west of Ireland.

Erythropoietin directly remodels the clonal composition of murine hematopoietic multipotent progenitor cells.

The cytokine erythropoietin (EPO) is a potent inducer of erythrocyte development and one of the most prescribed biopharmaceuticals. The action of EPO on erythroid progenitor cells is well established, but its direct action on hematopoietic stem and progenitor cells (HSPCs) is still debated. Here, using cellular barcoding, we traced the differentiation of hundreds of single murine HSPCs, after ex vivo EPO exposure and transplantation, in five different hematopoietic cell lineages, and observed the transient occurrence of high-output myeloid-erythroid-megakaryocyte-biased and myeloid-B-cell-dendritic cell-biased clones.

Sex-dependent influence of postweaning environmental enrichment in Angelman syndrome model mice.

Introduction: Angelman syndrome (AS) is a rare neurodevelopmental disorder caused by mutation or loss of UBE3A and marked by intellectual disability, ataxia, autism-like symptoms, and other atypical behaviors. One route to treatment may lie in the role that environment plays early in postnatal life. Environmental enrichment (EE) is one manipulation that has shown therapeutic potential in preclinical models of many brain disorders, including neurodevelopmental disorders.

Hematopoiesis in numbers.

Hematopoiesis is a dynamic process in which stem and progenitor cells give rise to the ~10 blood and immune cells distributed throughout the human body. We argue that a quantitative description of hematopoiesis can help consolidate existing data, identify knowledge gaps, and generate new hypotheses. Here, we review known numbers in murine and, where possible, human hematopoiesis, and consolidate murine numbers into a set of reference values.

Simulating CXCR5 Dynamics in Complex Tissue Microenvironments.

To effectively navigate complex tissue microenvironments, immune cells sense molecular concentration gradients using G-protein coupled receptors. However, due to the complexity of receptor activity, and the multimodal nature of chemokine gradients , chemokine receptor activity is poorly understood. To address this issue, we apply a modelling and simulation approach that permits analysis of the spatiotemporal dynamics of CXCR5 expression within an B-follicle with single-cell resolution.

Significant cognitive decline in Parkinson's disease exacerbates the reliance on visual feedback during upper limb reaches.

While upper limb reaches are often made in a feed-forward manner, visual feedback during the movement can be used to guide the reaching hand towards a target. In Parkinson's disease (PD), there is evidence that the utilisation of this visual feedback is increased. However, it is unclear if this is due solely to the characteristic slowness of movements in PD providing more opportunity for incorporating visual feedback to modify reach trajectories, or whether it is due to cognitive decline impacting (feed-forward) movement planning ability.

Transplant-associated thrombotic microangiopathy and immune haematological complications following intestine-containing organ transplantation: experience from over 100 consecutive cases.

Descriptions of passenger lymphocyte syndrome (PLS), immune cytopenias and transplant-associated thrombotic microangiopathy (TA-TMA) after intestine-containing transplants remain scarce. We describe our centre's experience of these complications from 2007 to 2019. Ninety-six patients received 103 transplants.
