Synovial innate immune exhaustion is associated with worse pain in knee osteoarthritis.

Objective: Uncontrolled pain remains a major clinical challenge in the management of knee osteoarthritis (OA), the most common disabling joint disease. Worse pain is associated with synovial innate immune cell infiltration (synovitis), but the role of innate immune regulatory cells in pain is unknown. Our objective was to identify synovial innate immune cell subsets and pathophysiologic mechanisms associated with worse pain in patients with knee OA.

Raised water temperature enhances benthopelagic links via intensified bioturbation and benthos-mediated nutrient cycling.

Sediment reworking by benthic infauna, namely bioturbation, is of pivotal importance in expansive soft-sediment environments such as the Wadden Sea. Bioturbating fauna facilitate ecosystem functions such as bentho-pelagic coupling and sediment nutrient remineralization capacities. Yet, these benthic fauna are expected to be profoundly affected by current observed rising sea temperatures.

The Relationship Between Work Engagement, Depression, Anxiety, and COVID-19 Anxiety in Physician Assistant Students.

Physician assistants (PAs) are subject to high levels of burnout, depressive symptoms, and anxiety, which can negatively impact quality of care and patient outcomes. Learning how to handle stress in the classroom may increase success and engagement in PA programs. The goal of this study was to characterize burnout, depressive symptoms, and anxiety in current PA students and examine the relationship between these factors and work engagement.

Genetic Stock Identification Reveals Mismatches Between Management Areas and Population Genetic Structure in a Migratory Pelagic Fish.

Sustainable fisheries management is important for the continued harvest of the world's marine resources, especially as they are increasingly challenged by a range of climatic and anthropogenic factors. One of the pillars of sustainable fisheries management is the accurate identification of the biological units, i.e.

The origin and maintenance of supergenes contributing to ecological adaptation in Atlantic herring.

Chromosomal inversions are associated with local adaptation in many species. However, questions regarding how they are formed, maintained and impact various other evolutionary processes remain elusive. Here, using a large genomic dataset of long-read and short-read sequencing, we ask these questions in one of the most abundant vertebrates on Earth, the Atlantic herring.

Patient perspectives on the risks of obesity treatment: An innovative health initiative stratification of obesity phenotypes to optimise future obesity therapy (IMI2 SOPHIA) qualitative study.

Background: The uptake of obesity treatments remains disproportionally low in people living with the disease, even with the advent and availability of GLP-1 agonists in recent years. Efforts to understand this discrepancy have centred on literature syntheses and Healthcare Professionals' (HCPs) perspectives on the barriers to obesity treatment. This study focuses on patient perspectives on the of obesity treatment.

Patient perceptions of success in obesity treatment: An IMI2 SOPHIA study.

Background: It is anticipated that by 2030, 20% of the world's population will live with obesity. Success in the management of obesity is predominately determined in terms of BMI or percentage weight loss, yet the limitations of these have been widely recognized. This study aimed to understand patient definitions of success in obesity treatment.

The W792R HCM missense mutation in the C6 domain of cardiac myosin binding protein-C increases contractility in neonatal mouse myocardium.

Missense mutations in cardiac myosin binding protein C (cMyBP-C) are known to cause hypertrophic cardiomyopathy (HCM). The W792R mutation in the C6 domain of cMyBP-C causes severe, early onset HCM in humans, yet its impact on the function of cMyBP-C and the mechanism through which it causes disease remain unknown. To fully characterize the effect of the W792R mutation on cardiac morphology and function in vivo, we generated a murine knock-in model.

The protocol: Synchronized nature-based and other outdoor experiences in virtual reality for hospice patients and their caregivers.

Background: Nature-based and other outdoor virtual reality (VR) experiences in head-mounted displays (HMDs) offer powerful, non-pharmacological tools for hospice teams to help patients undergoing end-of-life (EOL) transitions. However, the psychological distress of the patient-caregiver dyad is interconnected and highlights the interdependence and responsiveness to distress as a unit. Hospice care services and healthcare need strategies to help patients and informal caregivers with EOL transitions.

Patient perspectives on personalised medicine for obesity: An IMI2 SOPHIA Study.

Objective: Personalised medicine is seen as an exciting opportunity to improve the health outcomes of people with obesity. As research on phenotyping and personalised treatment for obesity rapidly advances, this study sought to understand patient preferences and perspectives on personalised medicine for obesity.

Methods: A participatory world café methodology was used to garner the perspectives of people living with obesity on the potential opportunities and limitations associated with a personalised approach to obesity risk identification and treatment.

Dietary inflammatory index (DII) and sleep quality, duration, and timing: A systematic review.

Sleep has strong inflammatory underpinnings and diet is one of the primary determinants of systemic inflammation. A systematic literature review was conducted to synthesize current research associating dietary inflammatory potential, as measured by the dietary inflammatory index (DII®) or the energy-adjusted DII (E-DII™) and sleep quality and duration. The National Library of Medicine (Medline), Web of Science, and PsycInfo databases were searched through March 2023.

"Treated as second class citizens" - the lived experience of obesity-related stigma: an IMI2 SOPHIA study.

Purpose: Obesity-related stigma impacts on and shapes the physical and psychosocial wellbeing of individuals living with obesity. Often absent from the literature in the field is the voice(s) of those living with obesity capturing the nuances of the lived experiences of obesity-related stigma.

Methods: This study adopted a qualitative approach encompassing individual ( = 15) and photovoice method ( = 12), with a purposeful sample of patients accessing treatment for obesity within the healthcare setting during 2021.

Enhancing the action of serotonin by three different mechanisms prevents spontaneous seizure-induced mortality in Dravet mice.

Objective: Sudden unexpected death in epilepsy (SUDEP) is an underestimated complication of epilepsy. Previous studies have demonstrated that enhancement of serotonergic neurotransmission suppresses seizure-induced sudden death in evoked seizure models. However, it is unclear whether elevated serotonin (5-HT) function will prevent spontaneous seizure-induced mortality (SSIM), which is characteristic of human SUDEP.

Bone formation by human paediatric marrow stromal cells in a functional allogeneic immune system.

Allogeneic stem-cell based regenerative medicine is a promising approach for bone defect repair. The use of chondrogenically differentiated human marrow stromal cells (MSCs) has been shown to lead to bone formation by endochondral ossification in immunodeficient pre-clinical models. However, an insight into the interactions between the allogeneic immune system and the human MSC-derived bone grafts has not been fully achieved yet.

The interplay of collagen, macrophages, and microcalcification in atherosclerotic plaque cap rupture mechanics.

The rupture of an atherosclerotic plaque cap overlying a lipid pool and/or necrotic core can lead to thrombotic cardiovascular events. In essence, the rupture of the plaque cap is a mechanical event, which occurs when the local stress exceeds the local tissue strength. However, due to inter- and intra-cap heterogeneity, the resulting ultimate cap strength varies, causing proper assessment of the plaque at risk of rupture to be lacking.

Incorporating strontium enriched amorphous calcium phosphate granules in collagen/collagen-magnesium-hydroxyapatite osteochondral scaffolds improves subchondral bone repair.

Osteochondral defect repair with a collagen/collagen-magnesium-hydroxyapatite (Col/Col-Mg-HAp) scaffold has demonstrated good clinical results. However, subchondral bone repair remained suboptimal, potentially leading to damage to the regenerated overlying neocartilage. This study aimed to improve the bone repair potential of this scaffold by incorporating newly developed strontium (Sr) ion enriched amorphous calcium phosphate (Sr-ACP) granules (100-150 μm).

How Feasible Are Digital Intraoperative Plain Radiographs in Orthopaedic Trauma Surgery?

The purpose of this study is to evaluate the feasibility and outcomes of obtaining routine intraoperative plain radiographs during orthopaedic trauma surgery. Seventy consecutive orthopaedic trauma patients in which intraoperative plain films were obtained in addition to fluoroscopy were reviewed. For each patient the time it took to obtain intraoperative plain radiographs was prospectively measured, in addition to the number of images taken, and quality of image.

Lactate- and immunomagnetic-purified hiPSC-derived cardiomyocytes generate comparable engineered cardiac tissue constructs.

Three-dimensional engineered cardiac tissue (ECT) using purified human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) has emerged as an appealing model system for the study of human cardiac biology and disease. A recent study reported widely used metabolic (lactate) purification of monolayer hiPSC-CM cultures results in an ischemic cardiomyopathy-like phenotype compared with magnetic antibody-based cell sorting (MACS) purification, complicating the interpretation of studies using lactate-purified hiPSC-CMs. Herein, our objective was to determine if use of lactate relative to MACS-purified hiPSC-CMs affects the properties of resulting hiPSC-ECTs.

How Fish Population Genomics Can Promote Sustainable Fisheries: A Road Map.

Maintenance of genetic diversity in marine fishes targeted by commercial fishing is a grand challenge for the future. Most of these species are abundant and therefore important for marine ecosystems and food security. Here, we present a road map of how population genomics can promote sustainable fisheries.

Synovial macrophage diversity and activation of M-CSF signaling in post-traumatic osteoarthritis.

Objective: Synovium is home to immune and stromal cell types that orchestrate inflammation following a joint injury; in particular, macrophages are central protagonists in this process. We sought to define the cellular and temporal dynamics of the synovial immune niche in a mouse model of post-traumatic osteoarthritis (PTOA), and to identify stromal-immune crosstalk mechanisms that coordinate macrophage function and phenotype.

Design: We induced PTOA in mice using a non-invasive tibial compression model of anterior cruciate ligament rupture (ACLR).

Case Report: Resolution of high grade anal squamous intraepithelial lesion with antibiotics proposes a new role for syphilitic infection in potentiation of HPV-associated ASCC.

Introduction: Human Papillomavirus (HPV) is the primary risk factor for the development of anal intraepithelial neoplasia (AIN) and is a leading risk factor for anogenital squamous cell carcinoma (ASCC). Despite common shared risk factors for both HPV and syphilis, co-infection is not well documented, and the role of syphilitic infection in HPV-associated AIN and ASCC potentiation is not defined.
