A targetable developmental program co-regulates angiogenesis and immune evasion.

Ultraviolet (UV)-induced DNA mutations produce genetic drivers of cutaneous melanoma initiation and numerous neoantigens that can trigger anti-tumor immune responses in the host. Consequently, melanoma cells must rapidly evolve to evade immune detection by simultaneously modulating cell-autonomous epigenetic mechanisms and tumor-microenvironment interactions. Angiogenesis has been implicated in this process; although an increase of vasculature initiates the immune response in normal tissue, solid tumors manage to somehow enhance blood flow while preventing immune cell infiltration.

Overloading And unpacKing (OAK) - droplet-based combinatorial indexing for ultra-high throughput single-cell multiomic profiling.

Multiomic profiling of single cells by sequencing is a powerful technique for investigating cellular diversity. Existing droplet-based microfluidic methods produce many cell-free droplets, underutilizing bead barcodes and reagents. Combinatorial indexing on microplates is more efficient for barcoding but labor-intensive.

Identification of natriuretic peptide receptor A-related gene expression signatures in podocytes in vivo reveals baseline control of protective pathways.

Natriuretic peptide receptor-A (NPR-A) is the principal receptor for the natriuretic peptides atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP). Targeted deletion of NPR-A in mouse glomerular podocytes significantly enhances renal injury in vivo in the DOCA-salt experimental model. It was therefore hypothesized that natriuretic peptides exert a direct protective effect on glomerular barrier integrity through activation of NPR-A and modulation of gene expression patterns in podocytes.

Hazard Ratios and Alternative Effect Measures: An Applied Illustration.

Purpose: Although the limitations of hazard ratios (HRs) for quantifying treatment effects in right-censored data have been widely discussed, HRs are still preferentially reported over other, more interpretable effect measures. This may stem from the fact that there are few applied examples that directly contrast the HR and its interpretation with alternative effect measures.

Methods: We analyzed data from two randomized clinical trials comparing panitumumab plus standard-of-care chemotherapy (SOCC) with SOCC alone as first- and second-line treatment for metastatic colorectal cancer.

Parental Leave: What Do Physician Societies Provide for Their Employees?

Introduction: Parental leave yields significant health benefits for parents and children. While many medical associations endorse parental leave, it is unknown what parental leave they provide for their employees.

Objective: To assess parental leave policies of national physician societies for their employees including paid versus unpaid and parity between birth mothers and non-birthing parents.

Status and timing of angiotensin receptor-neprilysin inhibitor implementation in patients with heart failure and reduced ejection fraction: Data from the Swedish Heart Failure Registry.

Aims: We explored timing, settings and predictors of angiotensin receptor-neprilysin inhibitor (ARNI) initiation in a large, nationwide cohort of patients with heart failure (HF) with reduced ejection fraction (HFrEF).

Methods And Results: Patients with HFrEF (ejection fraction <40%) registered in the Swedish HF Registry in 2017-2021 and naïve to ARNI were evaluated for timing and location of, and their characteristics at ARNI initiation. ARNI use increased from 8.

Antimicrobial Peptides Increase Line Tension in Raft-Forming Lipid Membranes.

The formation of phase separated membrane domains is believed to be essential for the function of the cell. The precise composition and physical properties of lipid bilayer domains play crucial roles in regulating protein activity and governing cellular processes. Perturbation of the domain structure in human cells can be related to neurodegenerative diseases and cancer.

First-line treatment for femoroacetabular impingement syndrome and hip-related quality of life: study protocol for a multicentre randomised controlled trial comparing a 6-month supervised strength exercise intervention to usual care (the Better Hip Trial).

Introduction: Femoroacetabular impingement syndrome (FAIS) is a motion-related and position-related clinical condition of the hip associated with pain, reduced physical function and hip-related quality of life (QoL). Interestingly, higher maximal muscle strength is associated with less pain, better physical function and improved QoL in people with FAIS. Furthermore, preliminary evidence suggests that a proportion of patients with FAIS respond positively to strength exercise as first-line treatment.

The RHCE gene encodes the chicken blood system I.

Background: There are 13 known chicken blood systems, which were originally detected by agglutination of red blood cells by specific alloantisera. The genomic region or specific gene responsible has been identified for four of these systems (A, B, D and E). We determined the identity of the gene responsible for the chicken blood system I, using DNA from multiple birds with known chicken I blood system serology, 600K and 54K single nucleotide polymorphism (SNP) data, and lowpass sequence information.

Skeletal muscle density performance for screening frailty in older adults with cancer and the impact of diabetes: The CARE Registry.

Introduction: Skeletal muscle density (SMD) measurements from imaging scans identify myosteatosis and could screen patients for geriatric assessment. We assessed SMD performance as a screening tool to identify older adults with cancer likely to be frail and who could benefit from in-depth assessment; we compared performance by sex and diabetes status.

Materials And Methods: We analyzed patients in the Cancer & Aging Resilience Evaluation (CARE) Registry.

IMPRESS-Norway: improving public cancer care by implementing precision medicine in Norway; inclusion rates and preliminary results.

Background And Purpose: In Norway, comprehensive molecular tumour profiling is implemented as part of the public healthcare system. A substantial number of tumours harbour potentially targetable molecular alterations. Therapy outcomes may improve if targeted treatments are matched with actionable genomic alterations.

Biocompatibility and Endothelial Permeability of Branched Polyglycidols Generated by Ring-Opening Polymerization of Glycidol with B(CF) under Dry and Wet Conditions.

Polyglycidol or polyglycerol (PG), a polyether widely used in biomedical applications, has not been extensively studied in its branched cyclic form (PG), despite extensive research on hyperbranched PG (HPG). This study explores the biomedical promise of PG, particularly its ability to cross the blood-brain barrier (BBB). We evaluate biocompatibility, endothelial permeability, and formation of branched linear PG (PG) as topological impurities in the presence of water.

The SaVe project - Sarcopenia and Vertigo in aging patients with colorectal cancer: A study protocol for three randomized controlled trials.

Introduction: Older patients with cancer range from fit to frail with various comorbidities and resilience to chemotherapy. Besides nausea and fatigue, a significant number of patients experience dizziness and impaired walking balance after chemotherapy, which can have great impact on their functional ability and health related quality of life. Symptoms are easily overlooked and therefore often underreported and managed, which is why symptoms could end up as long-lasting side effects.

Cytoreductive Nephrectomy in Select Primary Metastatic Renal Cell Carcinoma Patients: A Comprehensive Nationwide Outcome Analysis.

(1) Background: The role of cytoreductive nephrectomy (CN) is controversial in patients with primary metastatic renal cell carcinoma (mRCC). (2) Methods: We evaluated the impact of CN, or no CN, followed by first-line targeted therapy (TT) in a nationwide unselected cohort of 437 consecutive patients with primary mRCC over a two-year period with a minimum of five years of follow-up. Data sources were national registries supplemented with manually extracted information from individual patient medical records.

Painful differences between different pain scale assessments: The outcome of assessed pain is a matter of the choices of scale and statistics.

Objectives: Perceived pain is a multi-factorial subjective variable, commonly measured by numeric rating scales, verbal descriptive scales (VDS), or by a position on an analogue line (VAS). A major question is whether an individual's VAS and VDS pain assessments, on the same occasion, could be comparable. The aim was to compare continuous and discretized VAS pain data with verbal descriptive pain datasets from the Oswestry Disability Index (ODI) and the European Quality of Life Scale (EQ-5D) in paired pain datasets.

Multicenter randomized trial of deferred cytoreductive nephrectomy in synchronous metastatic renal cell carcinoma receiving checkpoint inhibitors: the NORDIC-SUN-Trial.

Background: Primary tumor removal by cytoreductive nephrectomy in synchronous metastatic renal cell carcinoma patients has been investigated in the context of various treatment regimens. Two randomized controlled trials investigated the role and timing of cytoreductive nephrectomy in the era of targeted therapy and demonstrated that upfront nephrectomy should no longer be performed when patients require systemic therapy. Superiority of checkpoint immunotherapy agents has led to a paradigm change from targeted therapies to immunotherapy-based first-line treatment in patients with primary metastatic disease; thus, deferred cytoreductive nephrectomy needs to be verified in the immunotherapy setting.

Evidence for minimally invasive treatment-A systematic review on surgical management of disc displacement.

Background: Surgical treatment of temporomandibular joint (TMJ) disc displacement (DD) has been established in different forms since over a century. Ther is a consensus to perform minimal invasive interventions as first-line surgical treatment since there are no evidence on best surgical practice yet.

Objective: The aim was to perform a complex systematic review (SR) on the topic-is there evidence for surgical treatment of TMJ DD?

Methods: The PICO was defined as DD patients (population), treated with different surgical interventions including arthrocentesis (intervention), compared with other or no treatment (control) regarding the outcome variables mandibular function, mouth opening capacity, TMJ pain, etcetera (outcome).

Dietary intake and nutritional status in patients with newly diagnosed inflammatory bowel disease: insights from the IBSEN III study.

Background: Dietary recommendations in inflammatory bowel disease (IBD) are inconclusive, and patients may follow restrictive diets with increased risk of malnutrition. The aim of this study was to compare dietary intakes and nutritional status in men and women with newly diagnosed IBD with a general population sample, and to investigate whether intakes were in line with the Nordic Nutrition Recommendations.

Methods: This was a cross-sectional study including adults≥ 40 years with IBD from the Inflammatory Bowel Disease in South-Eastern Norway (IBSEN) III cohort study.

Challenges in legitimizing further measures against smoking in jurisdictions with robust infrastructure for tobacco control: how far can the authorities allow themselves to go?

Background: According to a recently published study, approximately half of those who currently smoke in Norway have little or no desire to quit despite a hostile regulatory and socio-cultural climate for smoking. On this background, we discuss some challenges that regulators will face in a further tightening of structural measures to curb smoking.

Main Body: Central to our discussion is the research literature concerned with the concept of state-paternalism in tobacco control-the line between an ethically justified interference with the freedom of those who smoke and an exaggerated infringement disproportionate to the same people's right to live as they choose.

Predictors of reoperation after lung volume reduction surgery.

Objectives: Lung volume reduction surgery (LVRS) has proven an effective treatment for emphysema, by decreasing hyperinflation and improving lung function, activity level and reducing dyspnoea. However, postoperative air leak is an important complication, often leading to reoperation. Our aim was to analyse reoperations after LVRS and identify potential predictors.

Minimal residual disease status is the prognostic determinant following high-dose treatment for patients with multiple myeloma.

Background: The presence of minimal residual disease (MRD+) following autologous stem cell transplantation (ASCT) in multiple myeloma represents a poor prognostic factor for progression-free survival (PFS) and overall survival (OS).

Methods: At our department, we recommend lenalidomide maintenance for patients who are MRD+ after ASCT, while MRD-negative (MRD-) patients, after information about the national guidelines, were not advised to follow this regimen.

Results: Out of the total 228 patients, 175 received ASCT following first-line induction (MRD- 92 (53%), MRD+ 83 (47%), at 2 months post-ASCT), while 53 underwent ASCT after second-line treatment (MRD- 27 (51%), MRD+ 26 (49%), at the same time point).
