Aseptic loosening around total joint replacement in humans is regulated by miR-1246 and miR-6089 via the Wnt signalling pathway.

Background: Total joint replacement for osteoarthritis is one of the most successful surgical procedures in modern medicine. However, aseptic loosening continues to be a leading cause of revision arthroplasty. The diagnosis of aseptic loosening remains a challenge as patients are often asymptomatic until the late stages.

Development of a qPCR detection approach for pathogenic Burkholderia cenocepacia associated with fresh vegetables.

Natural environment serves as a reservoir for Burkholderia cepacia complex organisms, including the highly transmissible opportunistic human pathogen B. cenocepacia. Currently, there is a lack of an effective and quantitative method for B.

Healthy Communities Delaware:: Accelerating Place-Based Efforts to Improve the Vital Conditions for Health, Well-Being and Equity.

Healthy Communities Delaware (HCD) is a place-based initiative to improve health, well-being and equity across Delaware. HCD is a network of community-based and investment partners working to create thriving communities through improvement in the vital conditions. Vital conditions are the components of communities that we all need, all the time, to thrive and reach our full potential-- humane housing, a thriving natural world, lifelong learning, meaningful work and wealth, reliable transportation, basic needs for health and safety, and a sense of belonging and civic muscle.

Interstitial Lung Disease in Firefighters: An Emerging Occupational Hazard.

Introduction: Occupational risk factors for interstitial lung disease (ILD) are a remediable aspect of this progressive pulmonary disorder. The association between firefighting and ILD is unknown. Our objective was to assess the characteristics of firefighters with ILD from a large single-center ILD registry.

The Need for Robust Critique of Arts and Health Research: Young People, Art Therapy and Mental Health.

We describe work in progress to conduct a systematic review of research on effects of arts-based programs for mental health in young people. We are at the stage of searching for relevant studies through major databases and screening extant systematic reviews for additional research which meet our inclusion criteria. At this stage, however, concerns have arisen regarding both the quality of existing primary studies and of recently published systematic reviews in this area of arts and health.

Emergency Department Nursing Burnout and Resilience.

Burnout is a significant problem in emergency nursing, and it is associated with higher turnover rates than other disciplines of health care. Emergency nurses are highly susceptible to burnout due to continual exposure to traumatic events, varying work schedules, violence directed at staff, and, in recent times, due to the stressors of the COVID-19 pandemic. This literature review will (1) expose the causes of emergency department (ED) nurse burnout and (2) discuss strategies to build resilience in ED nurses.

New Insight into the Prevalence and Risk Factors for Three Distinct Hoof Conformation Traits in UK Commercial Sheep Flocks.

Lameness in sheep continues to be a global health, welfare and economic concern. Damaged, misshapen or overgrown feet have the potential to cause lameness either directly, or indirectly. There is a lack of understanding of the predisposing factors for different hoof conformation traits in sheep.

Prevalence and Temporal Dynamics of White Line Disease in Sheep: An Exploratory Investigation into Disease Distribution and Associated Risk Factors.

Lameness in sheep is a global health, welfare and economic concern. White line disease (WLD), also known as shelly hoof, is a prevalent, non-infectious cause of lameness, characterised by the breakdown of the white line. Little is known about the predisposing factors, nor the individual disease dynamics over time.

Characterisation of on Misshapen and Damaged Ovine Feet: A Longitudinal Study of Four UK Sheep Flocks.

is the causal agent of ovine footrot, a contagious disease of welfare and economic concern worldwide. Damaged feet may be subclinical carriers of and covertly spread infection. Accordingly, we evaluated the risk of misshapen and damaged feet on presence and load in four commercial UK sheep flocks.

Sheep farmers' attitudes towards lameness control: Qualitative exploration of factors affecting adoption of the lameness Five-Point Plan.

In 2014, best-practice recommendations to treat and control lameness in sheep in the UK were consolidated into a national program, the Five-Point Plan (5PP). As recent evidence suggests that only the minority of sheep farmers are implementing all management practices listed in the 5PP, qualitative investigation is vital to ensure future promotion is aligned with psychological and contextual factors affecting farmers' decision-making. This qualitative study sought to explore farmers' attitudes and the factors affecting uptake of best-practice measures listed in the 5PP.

Uptake of the lameness Five-Point Plan and its association with farmer-reported lameness prevalence: A cross-sectional study of 532 UK sheep farmers.

The aims of this research were to determine the uptake of a national strategy to reduce lameness in the UK flock, known as the Five-Point Plan (5 P P); explore the association between footrot vaccination (Footvax®) use and 5 P P adoption; investigate the management practices associated with farmer-reported percentage lameness through risk factor analysis; and identify the population attributable fractions of these management practices. In 2014, the 5 P P was launched to provide a practical, farm-level framework to help farmers reduce lameness to reach Farm Animal Welfare Committee (FAWC) targets. No published studies have explicitly explored its uptake in UK flocks nor its association with lameness prevalence.

School-Based Accommodations and Supports for Anxious Youth: Benchmarking Reported Practices Against Expert Perspectives.

: Although research has examined negatively reinforcing patterns of parental accommodation of youth anxiety, limited research considers school staff-led accommodations for students with anxiety. Further, the extent to which patterns of school staff-led accommodations/supports for anxiety align with anxiety expert perspectives remains unclear.: School staff across elementary, middle, and high schools who identified anxiety as their top student concern (N = 134) were surveyed about their use of 23 anxiety-focused accommodations/supports, as well as their own mental health literacy and emotional exhaustion.

Interventions for managing skeletal muscle spasticity following traumatic brain injury.

Background: Skeletal muscle spasticity is a major physical complication resulting from traumatic brain injury (TBI), which can lead to muscle contracture, joint stiffness, reduced range of movement, broken skin and pain. Treatments for spasticity include a range of pharmacological and non-pharmacological interventions, often used in combination. Management of spasticity following TBI varies from other clinical populations because of the added complexity of behavioural and cognitive issues associated with TBI.

Hydroxyurea therapy in UK children with sickle cell anaemia: A single-centre experience.

Introduction: Despite the demonstrated efficacy of hydroxyurea therapy, children with sickle cell anaemia in the UK are preferentially managed with supportive care or transfusion. Hydroxyurea is reserved for children with severe disease phenotype. This is in contrast to North America and other countries where hydroxyurea is widely used for children of all clinical phenotypes.

Non-tumour bone marrow lymphocytes correlate with improved overall survival in childhood acute lymphoblastic leukaemia.

Composition of tumour immune cell infiltrates correlates with response to treatment and overall survival (OS) in several cancer settings. We retrospectively examined immune cells present in diagnostic bone marrow aspirates from paediatric patients with B-cell acute lymphoblastic leukaemia. Our analysis identified a sub-group (∼30% of patients) with >2.

The cytokine and chemokine expression profile of nucleus pulposus cells: implications for degeneration and regeneration of the intervertebral disc.

Introduction: The aims of these studies were to identify the cytokine and chemokine expression profile of nucleus pulposus (NP) cells and to determine the relationships between NP cell cytokine and chemokine production and the characteristic tissue changes seen during intervertebral disc (IVD) degeneration.

Methods: Real-time q-PCR cDNA Low Density Array (LDA) was used to investigate the expression of 91 cytokine and chemokine associated genes in NP cells from degenerate human IVDs. Further real-time q-PCR was used to investigate 30 selected cytokine and chemokine associated genes in NP cells from non-degenerate and degenerate IVDs and those from IVDs with immune cell infiltrates (‘infiltrated’).

Inflammatory cytokines induce NOTCH signaling in nucleus pulposus cells: implications in intervertebral disc degeneration.

The objective of the study was to investigate how inflammatory cytokines, IL-1β, and TNF-α control NOTCH signaling activity in nucleus pulposus (NP) cells. An increase in expression of selective NOTCH receptors (NOTCH1 and -2), ligand (JAGGED2), and target genes (HES1, HEY1, and HEY2) was observed in NP cells following cytokine treatment. A concomitant increase in NOTCH signaling as evidenced by induction in activity of target gene HES1 and HEY1 promoters and reporter 12xCSL was seen.

Interleukin-1 receptor antagonist deficient mice provide insights into pathogenesis of human intervertebral disc degeneration.

Objectives: Interleukin 1 (IL-1) is potentially important in the pathogenesis of intervertebral disc (IVD) degeneration; increasing production of matrix degradation enzymes and inhibiting matrix synthesis. Although IL-1 polymorphisms have been linked to increased risk of IVD degeneration, it is still unclear whether IL-1 drives IVD degeneration in vivo or is a secondary feature of degeneration. Here, we investigated whether IVD degeneration could be induced spontaneously by the removal of the natural inhibitor of IL-1 (IL-1 receptor antagonist) in mice that lack a functional IL-1rn gene.

Tumor necrosis factor α- and interleukin-1β-dependent induction of CCL3 expression by nucleus pulposus cells promotes macrophage migration through CCR1.

Objective: To investigate tumor necrosis factor α (TNFα) and interleukin-1β (IL-1β) regulation of CCL3 expression in nucleus pulposus (NP) cells and in macrophage migration.

Methods: Quantitative reverse transcription-polymerase chain reaction and immunohistochemistry were used to measure CCL3 expression in NP cells. Transfections were used to determine the role of NF-κB, CCAAT/enhancer binding protein (C/EBPβ), and MAPK on cytokine-mediated CCL3 promoter activity.

Quality and consistency of guidelines for the management of mild traumatic brain injury in the emergency department.

Objectives: The objective was to provide an overview of the recommendations and quality of evidence-based clinical practice guidelines (CPGs) for the emergency management of mild traumatic brain injury (mTBI), with a view to informing best practice and improving the consistency of recommendations.

Methods: Electronic searches of health databases (MEDLINE, EMBASE, The Cochrane Library, PsycINFO), CPG clearinghouse websites, CPG developer websites, and Internet search engines up to January 2010 were conducted. CPGs were included if 1) they were published in English and freely accessible, 2) their scope included the management of mTBI in the emergency department (ED), 3) the date of last search was within the past 10 years (2000 onward), 4) systematic methods were used to search for evidence, and 5) there was an explicit link between the recommendations and the supporting evidence.

Doxorubicin in vivo rapidly alters expression and translation of myocardial electron transport chain genes, leads to ATP loss and caspase 3 activation.

Background: Doxorubicin is one of the most effective anti-cancer drugs but its use is limited by cumulative cardiotoxicity that restricts lifetime dose. Redox damage is one of the most accepted mechanisms of toxicity, but not fully substantiated. Moreover doxorubicin is not an efficient redox cycling compound due to its low redox potential.

Sibling violence silenced: rivalry, competition, wrestling, playing, roughhousing, benign.

In this article, sibling violence and the silence surrounding it is explicated through professional literature and research findings, exemplars from clinical practice, and statistics. Theoretical positions and discourse analysis have been used to help explain how regular broken bones, bruises, lacerations, and verbal humiliation can be minimized as normal sibling rivalry or roughhousing, which does not cause serious consequences. Nursing should be on the front lines of ending practices of violence.
