Autoimmune diseases often exhibit a preclinical stage before diagnosis. Electronic health record (EHR) based-biobanks contain genetic data and diagnostic information, which can identify preclinical individuals at risk for progression. Biobanks typically have small numbers of cases, which are not sufficient to construct accurate polygenic risk scores (PRS).

Article Synopsis
  • The study investigates the potential development of intraspinal pressure (ISP) elevation following traumatic spinal cord injury (TSCI) in a porcine model, particularly focusing on a hypothesized subdural compartment syndrome.
  • Researchers conducted a randomized, sham-controlled trial over 72 hours measuring ISP changes alongside various injury protocols to assess the impact of different contusion regimes on ISP.
  • Results showed no significant difference in ISP increases between TSCI and sham animals, indicating that the observed ISP changes were likely due to the surgical procedures rather than TSCI itself.

The tidal flow of seawater across the Earth's magnetic field induces electric currents and magnetic fields within the ocean and solid Earth. The amplitude and phase of the induced fields depend on the electrical properties of both seawater and the solid Earth, and thus can be used as proxies to study the seabed properties or potentially for monitoring long-term trends in the global ocean climatology. This article presents new global oceanic tidal magnetic field models and their uncertainties for four tidal constituents, including [Formula: see text] and even [Formula: see text], which was not reliably retrieved previously.

Article Synopsis
  • - This study investigates which models of vascular afterload best predict right-sided heart dysfunction in patients with newly diagnosed pulmonary hypertension (PH), focusing on factors like pulmonary vascular resistance (PVR) and pulmonary arterial compliance (PAC).
  • - Researchers analyzed data from 86 patients using right-sided heart catheterization and cardiac magnetic resonance imaging, revealing that PVR was the most accurate predictor for several measures of heart dysfunction, except when PVR was low, where PAC showed better predictive power.
  • - A combined model using PVR, PAC, and characteristic impedance provided the best prediction for right atrial volume changes, and a specific PAC threshold (<2.3 mL/mm Hg) was identified as a strong predictor for right-sided heart dysfunction in

Background: Fractional flow reserve (FFR) or non-hyperaemic pressure ratios are recommended to assess functional relevance of intermediate coronary stenosis. Both diagnostic methods require the placement of a pressure wire in the coronary artery during invasive coronary angiography. Quantitative flow ratio (QFR) is an angiography-based computational method for the estimation of FFR that does not require the use of pressure wires.

The "Kinguaariit Inuunerissut" (KI) camps, meaning "generations in well-being" in Greenlandic, was a pilot initiative designed to enhance cultural identity and intergenerational connections through culturally relevant activities. The outcomes of the KI-camps have informed the development of a broader KI-concept aiming at tailoring and implementing elements from KI-camps into early childhood education services, after-school programmes, and schools. In this paper we present the results from three workshop held in January 2024 in Sisimiut, Greenland where 28 older participants and 28 professionals were asked about essential knowledge and skills to be passed down to younger generations.

Background: Practicing the process of evidence-based practice (EBP) may be challenging for healthcare professionals and may be affected by their EBP knowledge, attitudes, self-efficacy, and behavior. We have some insight into how Norwegian healthcare professionals and students perceive EBP. However, research on the perception of EBP among primary healthcare professionals working in the Norwegian municipal health service is lacking.

Background: More than 50 % of cancer survivors experience late effects of cancer (LEC). Current models of follow-up care often prove inadequate, resulting in unresolved LEC. Given the pivotal role of community pharmacists as the most accessible healthcare professionals and the demonstrated benefits of evidence-based pharmacy services on patient centered care, exploring the potential contribution of community pharmacies in managing LEC is relevant.

Article Synopsis
  • - The study evaluates the effectiveness of two myoelectric prosthetic wrists (a commercial one and a new affordable "Utah wrist") in improving task performance for transradial amputees during a specific task.
  • - Results showed a significant reduction in task failure rates and compensatory movements when participants used the prosthetic wrists compared to when they did not use them.
  • - Importantly, using the prosthetic wrists did not increase cognitive load for users, suggesting they enhance dexterity without making the task mentally more challenging.

Introduction: The community health worker-led asthma home visiting model (CHW model) improved asthma outcomes and reduced health care costs among Massachusetts children with asthma. We projected cost savings associated with the expansion of the CHW model among pediatric Massachusetts Medicaid (MassHealth)-eligible patients with uncontrolled asthma (≥2 asthma-related emergency department visits per year).

Methods: We estimated 2019 costs associated with asthma-related hospitalizations and emergency department visits for MassHealth pediatric patients with uncontrolled asthma who also had 365 days of Medicaid eligibility in 2019.

Background: Continuous-flow left ventricular assist device (cfLVAD) use is effective in supporting patients with end-stage heart failure (ESHF). Reduced flow pulsatility within the systemic circulation in cfLVAD-supported patients may lead to alterations within the microcirculation. Temporal changes in microvasculature in relation to adverse events in cfLVAD-supported patients have not been studied.

Understanding the thermoelastic response of a nanostructure is crucial for the choice of materials and interfaces in electronic devices with improved and tailored transport properties at the nanoscale. Here, we show how the deposition of a MoS monolayer can strongly modify the nanoscale thermoelastic dynamics of silicon substrates close to their interface. We demonstrate this by creating a transient grating with extreme ultraviolet light, using ultrashort free-electron laser pulses, whose ≈84 nm period is comparable to the size of elements typically used in nanodevices, such as electric contacts and nanowires.

Computer simulations of coronary fractional flow reserve (FFR) based on coronary imaging have emerged as an attractive alternative to invasive measurements. However, most methods are proprietary and employ non-physiological assumptions. Our aims were to develop and validate a physiologically realistic open-source simulation model for coronary flow, and to use this model to predict FFR based on intracoronary optical coherence tomography (OCT) data in individual patients.

Although microalgae have only recently been recognized as part of the plant and soil microbiome, their application as biofertilizers has a tradition in sustainable crop production. Under consideration of their ability to produce the plant growth-stimulating hormone cytokinin (CK), known to also induce pathogen resistance, we have assessed the biocontrol ability of CK-producing microalgae. All pro- and eukaryotic CK-producing microalgae tested were able to enhance the tolerance of tobacco against Pseudomonas syringae pv.

Introduction: There is an increasing focus on the prevention of secondary injuries following traumatic spinal cord injury (TSCI), especially through improvement of spinal cord perfusion and immunological modulation. Such therapeutic strategies require translational and controlled animal models of disease progression of the acute phases of human TSCI.

Research Question: Is it possible to establish a 72-h sedated porcine model of incomplete thoracic TSCI, enabling controlled use of continuous, invasive, and non-invasive modalities during the entire sub-acute phase of TSCI?

Material And Methods: A sham-controlled trial was conducted to establish the model, and 10 animals were assigned to either sham or TSCI.
