Plasma biomarkers of amyloid, tau, astrogliosis, and axonal injury in a mixed memory clinic cohort.

Introduction: Studies have shown that blood biomarkers can differentiate dementia disorders. However, the diagnosis of dementia still relies primarily on cerebrospinal fluid and imaging modalities. The new disease-modifying treatments call for more widely applicable biomarkers.

Hemodynamic Characteristics and Prognostic Implication of Modified Society for Cardiovascular Angiography and Interventions Shock Classification in Comatose Patients With Out-of-Hospital Cardiac Arrest.

Background: Cardiogenic shock complicating acute myocardial infarction is associated with a high mortality rate. Cardiogenic shock after out-of-hospital cardiac arrest (OHCA) can be due to transient myocardial stunning but also reflect the increasing severity of ongoing heart failure. The Society for Cardiovascular Angiography and Interventions (SCAI) proposed a division of cardiogenic shock into 5 phenotypes, with cardiac arrest being a modifier.

Barriers for Responding to Pediatric Out-of-Hospital Cardiac Arrest During Emergency Medical Calls: A Qualitative Study.

Background: Rapid recognition of pediatric out-of-hospital cardiac arrest (POHCA) is a critical component to prompt initiation of bystander interventions. We aimed to investigate barriers for responding to POHCA during emergency medical calls.

Methods And Results: We included all POHCA calls (aged 0-18 years) from the emergency dispatch center in the Capital Region of Denmark between 2018 and 2021 and excluded POHCAs with no resuscitation order, found dead, where trained health professionals were on site, or where there was no possibility for initiation of cardiopulmonary resuscitation.

How to manage patients with germline variants: Recommendations from the Nordic working group on germline predisposition for myeloid neoplasms.

Increasing recognition of germline variants in patients with hematological malignancies prompted us to provide -specific recommendations for diagnosis, surveillance, and treatment. Causative germline variants in the predispose to the development of myeloid neoplasms (MNs), especially myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Almost 3%-5% of all patients with MDS or AML carry a pathogenic or likely pathogenic germline variant, while half of them acquire a somatic second hit in the other allele.

Ureteroenteric strictures after cystectomy: Side-specific risk factors and radiological assessment.

Objective: To evaluate risk factors contributing to side-specific benign ureteroenteric strictures following radical cystectomy with an ileal conduit.

Materials And Methods: Data obtained from patients with bladder cancer who underwent radical cystectomy with ileal conduit surgery between 2015 and 2018 were retrospectively analysed. Imaging prior to surgery was analysed, regarding calcifications in the aorta, sarcopenia and postoperatively for length of remaining left ureter.

Lower Recurrence Rates of Atrial Fibrillation and MACE Events After Early Compared to Late Ablation: A Danish Nationwide Register Study.

Background: Guidelines recommend prioritizing treatment with antiarrhythmic drugs before referral of patients with atrial fibrillation to ablation, delaying a potential subsequent ablation. However, delaying ablation may affect ablation outcomes. We sought to investigate the impact of duration from diagnosis to ablation on the risk of atrial fibrillation recurrence and adverse events.

Temporal Trends in the Initiation of Dialysis Among Patients With Heart Failure With or Without Diabetes: A Nationwide Study From 2002 to 2016.

Background: The incidence and distribution of acute and chronic dialysis among patients with heart failure (HF), stratified by diabetes, remain uncertain. We hypothesized that with improved survival and rising comorbidities, the demand for dialysis would increase over time.

Methods And Results: Patients with incident HF, aged 18 to 100 years, between 2002 and 2016, were identified using Danish nationwide registers.

Head and neck ultrasound training improves the diagnostic performance of otolaryngology residents.

Objective: Surgeon-performed head and neck ultrasound (US) is increasingly used among otolaryngologists in office-based and surgical settings. However, it is unknown how formal US training affects otolaryngology residents' diagnostic workup of patients with cervical pathology. This study examined how a formal US course for residents affected their outpatient clinic US performance and diagnostic accuracy.

Volunteer Responder Interventions in Out-of-Hospital Cardiac Arrest in Urban, Suburban, and Rural Areas.

Background: Patients with out-of-hospital cardiac arrest (OHCA) in rural areas experience longer emergency response times and have lower survival rates compared with patients in urban areas. Volunteer responders might improve care and outcomes for patients with OHCA specifically in rural areas. Therefore, we investigated volunteer responder interventions based on the degree of urbanization.

Impact of Acute Kidney Injury After Transcatheter Aortic Valve Replacement: A Nationwide Study.

Background: In patients undergoing transcatheter aortic valve replacement (TAVR), the impact of acute kidney injury (AKI) on the prognosis and especially on future kidney function has been sparsely examined, and data from large cohorts are warranted.

Methods And Results: With Danish nationwide registries, we identified all patients undergoing TAVR from 2014 to 2021 with no previous dialysis treatment. According to 2 plasma creatinine samples, we identified those suffering a postprocedural AKI within 21 days after TAVR.

Association of Real-Time Feedback and Cardiopulmonary-Resuscitation Quality Delivered by Ambulance Personnel for Out-of-Hospital Cardiac Arrest.

Background High-quality cardiopulmonary resuscitation (CPR) is associated with improved survival from out-of-hospital cardiac arrest and includes chest compression depth, chest compression rate, and chest compression fraction within international guideline recommendations. Previous studies have demonstrated divergent results of real-time feedback on CPR performance and patient outcomes. This study investigated the association between emergency medical service CPR quality and real-time CPR feedback for out-of-hospital cardiac arrest.

Are patients with eosinophilic esophagitis treated at an academic hospital comparable to a patient from a population-based cohort? Not in Denmark.

Background And Aim: Little are known about differences in eosinophilic esophagitis (EoE) patients in the general population compared with patients treated at academic hospitals. This might affect the generalizability of study results. The aims of the study were to compare clinical features, and complications of EoE between patients from a population-based cohort (DanEoE) and patients from an academic hospital cohort in Copenhagen (EoE-Cph).

Health and Well-Being in Older Adults With a Surgically Closed or an Unrepaired Ventricular Septal Defect.

Background Older adults with a congenital ventricular septal defect (VSD) recently exhibited reduced heart rate variability and exercise capacity. It is unknown whether these findings affect health-related quality of life. Methods and Results Adults with VSDs and healthy controls, all concurrently included as part of another clinical study, completed the Danish National Health Survey questionnaire.

The Early neo2 Registry: Transcatheter Aortic Valve Implantation With ACURATE in a European Population.

Background ACURATE is a transcatheter aortic valve implantation system consisting of a self-expanding bioprosthetic valve with supra-annular leaflet position and featuring innovations to facilitate placement accuracy and reduce paravalvular regurgitation. Methods and Results The goal of the Early neo2 (Early neo2 Registry of the ACURATE neo2 TAVI Prosthesis) was to gather real-life data on safety and efficacy in a European transcatheter aortic valve implantation population treated with ACURATE . Data were collected from 554 consecutive patients treated with ACURATE at 12 European sites (mean age, 82 years; 66% women; mean European System for Cardiac Operative Risk Evaluation II, 4.

A case of bilateral pneumothorax following computer-tomography guided transthoracic biopsy in a woman with suspected pulmonary cancer.

Computer-tomography-guided needle biopsies are useful for diagnosing, staging, and classification of peripheral pulmonary nodules. However, the procedure carries a risk of iatrogenic pneumothorax. This report describes a patient-case where a woman had undergone a computer-tomography guided biopsy.

Frailty, Treatments, and Outcomes in Older Patients With Myocardial Infarction: A Nationwide Registry-Based Study.

Background Guidelines recommend that patients with myocardial infarction (MI) receive equal care regardless of age. However, withholding treatment may be justified in elderly and frail patients. This study aimed to investigate trends in treatments and outcomes of older patients with MI according to frailty.

Association of Degree of Urbanization and Survival in Out-of-Hospital Cardiac Arrest.

Background Survival from out-of-hospital cardiac arrest (OHCA) varies across regions. The aim of this study was to evaluate the association between urbanization (rural, suburban, and urban areas), bystander interventions (cardiopulmonary resuscitation and defibrillation), and 30-day survival from OHCAs in Denmark. Methods and Results We included OHCAs not witnessed by ambulance staff in Denmark from January 1, 2016, to December 31, 2020.

GLP-1 Promotes Cortical and Medullary Perfusion in the Human Kidney and Maintains Renal Oxygenation During NaCl Loading.

Background GLP-1 (glucagon-like peptide-1) receptor agonists exert beneficial long-term effects on cardiovascular and renal outcomes. In humans, the natriuretic effect of GLP-1 depends on GLP-1 receptor interaction, is accompanied by suppression of angiotensin II, and is independent of changes in renal plasma flow. In rodents, angiotensin II constricts vasa recta and lowers medullary perfusion.

Congenital Heart Disease and Fertility: A Danish Nationwide Cohort Study Including Both Men and Women.

Background Despite an increasing number of patients with congenital heart disease (CHD) reaching reproductive age, the fertility of these patients remains undescribed. Therefore, the aim of the study was to evaluate the fertility in men and women with CHD by estimating the risk of infertility and comparing the birth rates, proportions of individuals becoming parents or remaining childless, and the number of children per parent with unaffected individuals. Methods and Results The study population consisted of individuals born between 1977 and 2000.
