Effects of valsartan vs amlodipine and achieved lower blood pressure on the incidence of end-stage kidney disease: The VALUE Trial.

Background: There is a paucity of data investigating the impact of antihypertensive drug classes and blood pressure (BP) treatment targets on the incidence of end-stage kidney disease (ESKD). In patients with high-risk hypertension aged 50-80 years or above, we aimed to, 1) compare effects of valsartan, an angiotensin receptor blocker, with amlodipine, a calcium channel blocker and, 2) assess the effect of achieving systolic BP <135 vs ≥135 mmHg on the ESKD incidence.

Methods: The VALUE Trial was a multicenter prospective double-blinded randomized clinical trial in patients with essential hypertension and high cardiovascular risk including known coronary disease, left ventricular hypertrophy and previous stroke, in which ESKD was a secondary endpoint defined as progression to kidney transplant and/or dialysis.

Antibodies against SARS-CoV-2 spike protein in the cerebrospinal fluid of COVID-19 patients and vaccinated controls: a multicentre study.

Introduction: SARS-CoV-2 antibodies in the cerebrospinal fluid (CSF) of COVID-19 patients possibly reflect blood-cerebrospinal fluid barrier (BCB) disruption due to systemic inflammation. However, some studies indicate that CSF antibodies signal a neurotropic infection. Currently, larger studies are needed to clarify this, and it is unknown if CSF antibodies appear solely after infection or also after COVID-19 vaccination.

Low-value imaging: concept analysis and definition.

Background: While there is an extensive literature on low-value imaging, there is no agreed definition of the concept. However, a clear and consistent definition of low-value imaging is crucial for providing comparable and targeted research, and for increasing the quality, safety, effectiveness, efficiency, and sustainability of imaging services. Accordingly, the purpose of this study is to provide a definition of low-value imaging.

Artificial intelligence - the emperor's new clothes?

There is a massive hype of artificial intelligence (AI) allegedly revolutionizing medicine. However, algorithms have been at the core of medicine for centuries and have been implemented in technologies such as computed tomography and magnetic resonance imaging machines for decades. They have given decision support in electrocardiogram machines without much attention.

Tubulin-Targeted Therapy in Melanoma Increases the Cell Migration Potential by Activation of the Actomyosin Cytoskeleton─An In Vitro Study.

One of the most dangerous aspects of cancers is their ability to metastasize, which is the leading cause of death. Hence, it holds significance to develop therapies targeting the eradication of cancer cells in parallel, inhibiting metastases in cells surviving the applied therapy. Here, we focused on two melanoma cell lines─WM35 and WM266-4─representing the less and more invasive melanomas.

"My Biomarkers Are Fine, Thank You": On the Biomarkerization of Modern Medicine.

Biomarkers are becoming crucial in ever more medical tasks and are proposed to change medicine in profound ways. By biomarking ever more attributes of human life, they tend to blur the distinction between health and disease and come to characterize life as such. Not only do biomarkers strongly influence the professional conception of disease by pervading ever more diagnoses, but they also impact patients' experience of illness.

Towards a reduced order model for EVAR planning and intra-operative navigation.

Introduction: The pre-operative planning and intra-operative navigation of the endovascular aneurysm repair (EVAR) procedure are currently challenged by the aortic deformations that occur due to the insertion of a stiff guidewire. Hence, a fast and accurate predictive tool may help clinicians in the decision-making process and during surgical navigation, potentially reducing the radiations and contrast dose. To this aim, we generated a reduced order model (ROM) trained on parametric finite element simulations of the aortic wall-guidewire interaction.

Cognitive remediation therapy for patients with eating disorders: a qualitative study.

Background: Transdiagnostic Cognitive Remediation Therapy (TCRT) is a new adaptation of cognitive remediation therapy for eating disorders (EDs) developed to address common cognitive difficulties across ED diagnoses (i.e., cognitive flexibility, central coherence, and impulsivity).

Cooperation across healthcare service levels for medication reviews in older people with polypharmacy admitted to a municipal in-patient acute care unit (The COOP II Study): study protocol for a randomized controlled trial.

Background: Polypharmacy and inappropriate drug use are associated with adverse health outcomes in older people. Collaborative interventions between geriatricians and general practitioners have demonstrated effectiveness in improving clinical outcomes for complex medication regimens in home-dwelling patients. Since 2012, Norwegian municipalities have established municipal in-patient acute care (MipAC) units, designed to contribute towards reducing the number of hospital admissions.

A seawater field study of crude and fuel oil depletion in Northern Norway at two different seasons - Chemistry and bacterial communities.

After marine oil spills, natural processes like photooxidation and biodegradation can remove the oil from the environment. However, these processes are strongly influenced by environmental conditions. To achieve a greater understanding of how seasonal variations in temperature, light exposure and the bacterial community affect oil depletion in the marine environment, we performed two field experiments during the spring and autumn.

Exploring the Impact of Age and Pre-Stroke Modified Rankin Scale in Elderly Thrombectomy: A 15-Year Single-Center Experience.

Sustainability in healthcare by reducing low-value imaging - A narrative review.

Objectives: This narrative review aims to present the concept of value in imaging and explore why we conduct low-value procedures, how to reduce this wasteful use, and what we could gain from reducing low-value imaging.

Key Findings: Imaging of low value to the patient contributes to thousands of metric tons of CO emissions, costing several billion US dollars annually. With a 20% reduction in low-value imaging, we would reduce the waste of resources related to 7.

Detecting normal and cancer skin cells via glycosylation and adhesion signatures: A path to enhanced microfluidic phenotyping.

Recruiting circulating cells based on interactions between surface receptors and corresponding ligands holds promise for capturing cells with specific adhesive properties. Our study investigates the adhesion of skin cells to specific lectins, particularly focusing on advancements in lectin-based biosensors with diagnostic potential. We explore whether we can successfully capture normal skin (melanocytes and keratinocytes) and melanoma (WM35, WM115, WM266-4) cells in a low-shear flow environment by coating surfaces with lectins.

Reporting radiographers in Norway - A qualitative study on implementation, organisation, and outcomes.

Introduction: Worldwide, there is an increasing use of imaging services and a shortage of radiologists. One potential solution to this challenge involves introducing task shifting, where radiographers actively contribute to reporting diagnostic images alongside radiologists. This study explored the purpose and value of reporting radiographers in Norway's imaging departments.

Profiling of serum metabolome of breast cancer: multi-cancer features discriminate between healthy women and patients with breast cancer.

Introduction: The progression of solid cancers is manifested at the systemic level as molecular changes in the metabolome of body fluids, an emerging source of cancer biomarkers.

Methods: We analyzed quantitatively the serum metabolite profile using high-resolution mass spectrometry. Metabolic profiles were compared between breast cancer patients (n=112) and two groups of healthy women (from Poland and Norway; n=95 and n=112, respectively) with similar age distributions.

Ultrasound enhanced diffusion in hydrogels: An experimental and non-equilibrium molecular dynamics study.

Focused ultrasound has experimentally been found to enhance the diffusion of nanoparticles; our aim with this work is to study this effect closer using both experiments and non-equilibrium molecular dynamics. Measurements from single particle tracking of 40 nm polystyrene nanoparticles in an agarose hydrogel with and without focused ultrasound are presented and compared with a previous experimental study using 100 nm polystyrene nanoparticles. In both cases, we observed an increase in the mean square displacement during focused ultrasound treatment.

Impact of teratoma on survival probabilities of patients with metastatic non-seminomatous germ cell cancer: Results from the IGCCCG Update Consortium.

Aims: To resolve the ongoing controversy surrounding the impact of teratoma (TER) in the primary among patients with metastatic testicular non-seminomatous germ-cell tumours (NSGCT).

Patients And Methods: Using the International Germ Cell Cancer Collaborative Group (IGCCCG) Update Consortium database, we compared the survival probabilities of patients with metastatic testicular GCT with TER (TER) or without TER (NTER) in their primaries corrected for known prognostic factors. Progression-free survival (5y-PFS) and overall survival at 5 years (5y-OS) were estimated by the Kaplan-Meier method.

Moral obligations towards human persons' wellbeing versus their suffering: An analysis of perspectives of moral philosophy.

What do we owe other persons? Are we as much obliged to promote their wellbeing as we are to reduce their suffering? This question is crucial for a range of social institutions and welfare services, and especially for the health services. To address this question the article investigates prominent positions and arguments in moral philosophy. It finds that while classical utilitarianism claims that there is symmetry in the moral obligation with respect to peoples' wellbeing and their suffering, a wide range of other positions and perspectives argue for an asymmetric relationship with stronger moral obligations towards other persons' suffering than towards their wellbeing.

Cost of Low-Value Imaging Worldwide: A Systematic Review.

Background And Objective: Imaging with low or no benefit for the patient undermines the quality of care and amounts to vast opportunity costs. More than 3.6 billion imaging examinations are performed annually, and about 20-50% of these are of low value.
