Congestive heart failure after anthracycline-containing treatment for Hodgkin lymphoma: A Swedish matched cohort study.

Introduction: Congestive heart failure (CHF) is a known complication after anthracyclines and radiotherapy for classical Hodgkin lymphoma (cHL). Contemporary cHL treatment may be associated with less risk because radiotherapy use and techniques have changed substantially over time.

Methods: In this study, Swedish cHL patients diagnosed in 2000-2018, and treated with adriamycin [doxorubicin], bleomycin, vinblastine, and dacarbazine (ABVD) or bleomycin, etoposide, Adriamycin [doxorubicin], cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP), were matched 1:10 to the general population on birth year and sex to investigate relative rates and cumulative risks of CHF.

Effects of dopamine β-hydroxylase inhibition in pressure overload-induced right ventricular failure.

Activation of the sympathetic nervous system is observed in pulmonary arterial hypertension patients. This study investigates whether inhibiting the conversion of dopamine into noradrenaline by dopamine -hydroxylase (DH) inhibition with BIA 21-5337 improved right ventricular (RV) function or remodeling in pressure overload-induced RV failure. RV failure was induced in male Wistar rats by pulmonary trunk banding (PTB).

Radial head arthroplasty diameter impact on elbow kinematics evaluated by dynamic radiostereometric analysis.

Purpose: Radial head arthroplasty (RHA) reestablishes elbow stability after complex radial head fracture, but complication rates are high, possibly due to inappropriate implant sizing. Knowledge of impact of radial head implant diameter on elbow kinematics is limited and warranted. This study evaluated elbow kinematics of different radial head implant diameters after RHA using dynamic radiostereometric analysis (dRSA).

Revascularization Therapies for Ischemic Stroke and Association With Risk of Epilepsy: A Danish Nationwide Register-Based Study.

Background: The association between stroke revascularization therapies and poststroke epilepsy is only sparsely investigated, and results are conflicting. The aim of this study is to investigate whether stroke revascularization therapies are associated with different risks of poststroke epilepsy.

Methods And Results: We conducted a nationwide, register-based, propensity score-matched cohort study.

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.

Self-Performed Dietary Sodium Reduction and Blood Pressure in Patients With Essential Hypertension: A Randomized Clinical Trial.

Background: Hypertension is the leading risk factor for cardiovascular disease worldwide. Patients with blood pressure (BP) response to dietary sodium reduction are referred to as "salt sensitive." Salt sensitivity (SS) might be due to differences in sodium storage capacity and the erythrocyte SS examines this capacity of the red blood cells.

ALM/BMI: A Clinically Superior Index for Identifying Skeletal Muscle Dysfunction in Patients With Heart Failure.

Background: Skeletal muscle wasting is critical in patients with heart failure (HF). Whereas prior studies have employed appendicular lean mass (ALM) normalized by height squared to identify low skeletal muscle mass, the potential of ALM normalized to body mass index (ALM/BMI) remains unexplored in patients with HF. In this study, we compared the use of 2 skeletal muscle mass indices in patients with HF to examine their sex-specific correlations with measures of physical capacity, quality of life, and daily physical activity.

Short-Chain Fatty Acid Butyrate Is an Inotropic Agent With Vasorelaxant and Cardioprotective Properties.

Background: The heart can metabolize the microbiota-derived short-chain fatty acid butyrate. Butyrate may have beneficial effects in heart failure, but the underlying mechanisms are unknown. We tested the hypothesis that butyrate elevates cardiac output by mechanisms involving direct stimulation of cardiac contractility and vasorelaxation in rats.

Enantiomer-Specific Cardiovascular Effects of the Ketone Body 3-Hydroxybutyrate.

Background: The ketone body 3-hydroxybutyrate (3-OHB) increases cardiac output (CO) by 35% to 40% in healthy people and people with heart failure. The mechanisms underlying the effects of 3-OHB on myocardial contractility and loading conditions as well as the cardiovascular effects of its enantiomeric forms, D-3-OHB and L-3-OHB, remain undetermined.

Methods And Results: Three groups of 8 pigs each underwent a randomized, crossover study.

Return to Work After Refractory Out-of-Hospital Cardiac Arrest in Patients Managed With or Without Extracorporeal Cardiopulmonary Resuscitation: A Nationwide Register-Based Study.

Background: Extracorporeal cardiopulmonary resuscitation (ECPR) is increasingly used for refractory out-of-hospital cardiac arrest (OHCA). However, survivors managed with ECPR are at risk of poor functional status. The purpose of this study was to investigate return to work (RTW) after refractory OHCA.

Association Between Defibrillation Using LIFEPAK 15 or ZOLL X Series and Survival Outcomes in Out-of-Hospital Cardiac Arrest: A Nationwide Cohort Study.

Background: Defibrillation is essential for achieving return of spontaneous circulation (ROSC) following out-of-hospital cardiac arrest (OHCA) with shockable rhythms. This study aimed to investigate if the type of defibrillator used was associated with ROSC in OHCA.

Methods And Results: This study included adult patients with OHCA from the Danish Cardiac Arrest Registry from 2016 to 2021 with at least 1 defibrillation by the emergency medical services.

Transitory Activation and Improved Transition from Erosion to Formation within Intracortical Bone Remodeling in Hypoparathyroid Patients Treated with rhPTH(1-84).

In hypoparathyroidism, lack of parathyroid hormone (PTH) leads to low calcium levels and decreased bone remodeling. Treatment with recombinant human PTH (rhPTH) may normalize bone turnover. This study aimed to investigate whether rhPTH(1-84) continued to activate intracortical bone remodeling after 30 months and promoted the transition from erosion to formation and whether this effect was transitory when rhPTH(1-84) was discontinued.

External Validation of Proposed American Heart Association Algorithm for Cardiovascular Screening Before Kidney Transplantation.

Background: Screening for cardiovascular disease is currently recommended before kidney transplantation. The present study aimed to validate the proposed algorithm by the American Heart Association (AHA-2022) considering cardiovascular findings and outcomes in kidney transplant candidates, and to compare AHA-2022 with the previous recommendation (AHA-2012).

Methods And Results: We applied the 2 screening algorithms to an observational cohort of kidney transplant candidates (n=529) who were already extensively screened for coronary heart disease by referral to cardiac computed tomography between 2014 and 2019.

Prophylaxis with low dose tranexamic acid in acute myeloid leukemia patients undergoing intensive chemotherapy.

Patients suffering from acute myeloid leukemia (AML) carry a high risk of serious bleeding complications due to severe thrombocytopenia for long periods of time during treatment. Prior to prophylactic platelet transfusion becoming the standard of care, intracranial bleeding was a major contributor to death in AML patients. However, despite prophylactic platelet transfusions, up to 79% of patients with AML experience clinically significant bleeding during treatment.

Lymphatic Abnormalities on Magnetic Resonance Imaging in Single-Ventricle Congenital Heart Defects Before Glenn Operation.

Background In the palliative pathway of single-ventricle physiology, lymphatic abnormalities on T2-weighted magnetic resonance imaging have been shown after the Glenn operation. It is believed that postsurgical hemodynamic changes contribute to the lymphatic changes.However, little is known about how early these abnormalities occur.

Thiamine for the Treatment of Cardiac Arrest-Induced Neurological Injury: A Randomized, Blinded, Placebo-Controlled Experimental Study.

Background Thiamine supplementation has demonstrated protective effects in a mouse model of cardiac arrest. The aim of this study was to investigate the neuroprotective effects of thiamine in a clinically relevant large animal cardiac arrest model. The hypothesis was that thiamine reduces neurological injury evaluated by neuron-specific enolase levels.

Preadmission Opioid Use and 1-Year Mortality Following Incident Myocardial Infarction: A Danish Population-Based Cohort Study (1997-2016).

Background Opioid use has been linked to an increased risk of myocardial infarction and cardiovascular mortality, but the prognostic impact of opioid use before an incident myocardial infarction is largely unknown. Methods and Results We conducted a nationwide population-based cohort study including all patients hospitalized for an incident myocardial infarction in Denmark (1997-2016). Based on their last redeemed opioid prescription before admission, patients were categorized as current users (0-30 days), recent users (31-365 days), former users (>365 days), and nonusers.

Impact of age-dependent red blood cell parameters on α-globin gene genotyping in children.

When screening for α-thalassemia in children, adult cut-offs for mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) are generally applied to guide genetic evaluation. However, the normal ranges for MCV and MCH are lower in children than in adults, so we hypothesized that using age-matched cut-offs could lead to a more rational diagnostic strategy. The aim of this study was to evaluate if age-matched cut-offs could be applied advantageously.

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.

Lifetime Burden of Morbidity in Patients With Isolated Congenital Ventricular Septal Defect.

Background The lifetime burden of morbidity in patients with isolated congenital ventricular septal defect (VSD) is not completely described. Methods and Results In a population-based cohort study in Denmark using nationwide medical registries, we included 8006 patients diagnosed with a congenital VSD before 2018 along with 79 568 randomly selected controls from the general Danish population matched by birth year and sex. Concomitant congenital cardiac malformations and chromosomal abnormalities were excluded.
