Primary vs Staged Biventricular Repair for Neonatal IAA with VSD and LVOTO.

Background: This study sought to determine the safety of primary and staged biventricular repair in neonates with interrupted aortic arch (IAA), ventricular septal defect (VSD), and severe left ventricular outflow tract obstruction (LVOTO).

Methods: Patients with a fundamental diagnosis of IAA and VSD between 2015 and 2020 were extracted from The Society of Thoracic Surgeons National Database by using a Participant User File. The objective was to compare outcomes for neonates undergoing primary and staged Yasui and Ross operations.

The Melody Valve in Small Children Undergoing First Mitral Valve Replacement: Better Than Mechanical?

Background: In small children with left atrioventricular valve dysfunction, valve repair is preferred but some will require valve replacement. No prosthetic valve has growth potential, bioprostheses have poor durability, and mechanical prostheses have high rates of thromboembolic and hemorrhagic complications. We reviewed our experience with a modified bovine jugular vein valve designed for use in the right ventricular outflow tract (Melody valve, Medtronic) and compared this with contemporary mechanical valve replacement.

Protective effects of Mycobacterium vaccae ATCC 15483 against "Western"-style diet-induced weight gain and visceral adiposity in adolescent male mice.

The prevalence of noncommunicable inflammatory disease is increasing in modern urban societies, posing significant challenges to public health. Novel prevention and therapeutic strategies are needed to effectively deal with this issue. One promising approach is leveraging microorganisms such as Mycobacterium vaccae ATCC 15483, known for its anti-inflammatory, immunoregulatory, and stress-resilience properties.

Urinary Tract Infection in Children and the Potential Role of Pivmecillinam as a Treatment Option.

We investigated the potential role of pivmecillinam in the treatment of urinary tract infections in children. Among 351 children (0-6 years) with urinary tract infections, 83% could be treated with pivmecillinam following urine culture. Resistance was highest in infants (0-3 months) caused by the high prevalence of Enterococcus faecalis.

Nursing Home Admission and Home Care Initiation After Acute Aortic Dissection: A Nationwide Registry-Based Cohort Study.

Background: Little is known about long-term outcomes beyond survival following acute aortic dissection. The aim of this research was to evaluate rates of home care initiation and nursing home admission during the first year after discharge and to assess factors associated with these needs.

Methods: All patients in Denmark with a first-time diagnosis of acute aortic dissection type A or B between 2006 and 2015 were identified using national registries.

Cardiovascular disease in adults with osteogenesis imperfecta: Clinical characteristics, care recommendations and research priorities identified using a modified Delphi technique.

Osteogenesis imperfecta (OI) is a multisystem disorder most often caused by pathogenic variants in genes that encode type I collagen. Type I collagen is abundant not only in bone but also in multiple tissues including skin, tendons, cornea, blood vessels and heart. Thus, OI can be expected to affect cardiovascular system, and there are numerous reports of cardiovascular disease (CVD) in people with OI.

No associations between neuroborreliosis in children and psychiatric neurodevelopmental disorders: a nationwide, population-based, matched cohort study.

Background: It has been suggested that neuroborreliosis in children can manifest as psychiatric neurodevelopmental disorders or cause long-term neurodevelopmental sequelae. However, previous studies were limited by size and design.

Methods: We performed a nationwide, population-based, matched cohort study in Denmark between 1995 and 2021.

Individual risk assessment for rupture of abdominal aortic aneurysm using artificial intelligence.

Objective: This study aimed to develop a prediction tool to identify abdominal aortic aneurysms (AAAs) at increased risk of rupture incorporating demographic, clinical, imaging, and medication data using artificial intelligence (AI).

Design: A development and validation study for individual prognosis using AI in a case-control design.

Methods: From two Danish hospitals, all available ruptured AAA cases between January 2009 and December 2016 were included in a ratio of 1:2 with elective surgery controls.

Three-Dimensional Imaging Defines Straddling Mitral Valve Anatomy to Allow Successful Biventricular Repair.

Biventricular repair of a straddling mitral valve (MV) can involve relocating ectopic papillary muscles and chordae. However, this increases operative complexity and risks MV incompetence. We describe a nine-month-old with D-transposition of the great arteries and straddling MV.

The mitochondrial mRNA-stabilizing protein SLIRP regulates skeletal muscle mitochondrial structure and respiration by exercise-recoverable mechanisms.

Decline in mitochondrial function is linked to decreased muscle mass and strength in conditions like sarcopenia and type 2 diabetes. Despite therapeutic opportunities, there is limited and equivocal data regarding molecular cues controlling muscle mitochondrial plasticity. Here we uncovered that the mitochondrial mRNA-stabilizing protein SLIRP, in complex with LRPPRC, is a PGC-1α target that regulates mitochondrial structure, respiration, and mtDNA-encoded-mRNA pools in skeletal muscle.

Outpatient Management of Patients Conditioned with Fludarabine and Treosulfan prior to Allogeneic Hematopoietic Cell Transplantation.

Allogenic hematopoietic cell transplantation (allo-HCT) with myeloablative conditioning traditionally requires 30 days of hospitalization after stem cell infusion. However, advancements in supportive and prophylactic care have allowed for a trend toward outpatient management of allo-HCT, potentially leading to improved patient quality of life and increased cost-effectiveness of the procedure. In 2014, fludarabine and treosulfan (FluTreo) conditioning was introduced as a myeloablative regimen with reduced toxicity at Copenhagen University Hospital, Rigshospitalet (CUH).

Medical practitioners' experiences and considerations when managing sleep medication for adolescents and young adults.

Introduction: The prevalence of sleep disorders and use of sleep medication, particularly melatonin, are rising among adolescents and young adults (13-24 years). In Denmark, melatonin is approved for use in children with autism and ADHD up to 18 years of age, with other prescriptions being off-label in these age groups. The perspectives of medical practitioners on prescribing sleep medications to this age group remain largely unexplored.

Recently, semi-synthetic cannabinoids have entered the illegal market and are produced to mimic the psychoactive effects of tetrahydrocannabinol (THC). This is a case report of a 19-year-old man, who was hospitalized due to severe sedation, hypotension and tachy- and bradycardia after ingestion of the semi-synthetic cannabinoids hexahydrocannabinol (HHC) and hexahydrocannabiphorol (HHC-P) mixed in food. HHC-P, HHC and metabolites were identified in blood samples.

Diabetic retinopathy (DR) is the most common complication in patients with diabetes, and screening for sight-threatening end-stages is indicated to avoid severe visual loss. Screening of DR is nationally implemented in Denmark according to evidence-based national guidelines, which includes the use of individualised screening intervals. Treatment is indicated for proliferative DR and diabetic macular oedema, and treatment modalities include retinal laser therapy, intravitreal angiostatic therapy, and vitrectomy.

Re-organization of Pacific overturning circulation across the Miocene Climate Optimum.

The response of the ocean overturning circulation to global warming remains controversial. Here, we integrate a multiproxy record from International Ocean Discovery Program Site U1490 in the western equatorial Pacific with published data from the Pacific, Southern and Indian Oceans to investigate the evolution of deep water circulation during the Miocene Climate Optimum (MCO) and Middle Miocene Climate Transition (MMCT). We find that the northward export of southern-sourced deep waters was closely tied to high-latitude climate and Antarctic ice cover variations.

Neurofilament light chain as a biomarker of chemotherapy-induced peripheral neuropathy.

Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect of chemotherapy. The frequency of CIPN ranges from one in three to almost all patients depending on type of chemotherapy and dose. It causes symptoms that can range from sensitivity to touch and numbness to neuropathic pain in hands and feet.

Neural Tube Organoids: A Novel System to Study Developmental Timing.

The neural tube (NT) is a transient structure formed during embryogenesis which develops into the brain and spinal cord. While mouse models have been commonly used in place of human embryos to study NT development, species-specific differences limit their applicability. One major difference is developmental timing, with NT formation from the neural plate in 16 days in humans compared to 4 days in mice, as well as differences in the time taken to form neuronal subtypes and complete neurogenesis.

Risk of psychiatric neurodevelopmental disorders after meningitis in childhood: a nationwide, population-based cohort study.

Background: Few studies have investigated the risk of psychiatric neurodevelopmental disorders (PNDD) after childhood meningitis.

Methods: Nationwide population-based cohort study (Denmark, 1995-2021) of children with positive cerebrospinal fluid for bacteria or enterovirus, stratified on age as young infants (0 to <90 days,  = 637) or older children (≥90 days to <17 years,  = 1,218). We constructed a comparison cohort from the general population ( = 18,550), and cohorts of siblings of participants.

Mosaic chromosomal alterations in hematopoietic cells and clinical outcomes in patients with multiple myeloma.

Mosaic chromosomal alterations (mCAs) in hematopoietic cells increase mortality and risk of hematological cancers and infections. We investigated the landscape of mCAs and their clinical consequences in 976 patients with multiple myeloma undergoing high-dose chemotherapy and autologous stem cell support (ASCT) with median 6.4 years of follow-up.

The human AMPKγ3 R225W mutation negatively impacts site-1 nucleotide binding and does not enhance basal AMPKγ3-associated activity nor glycogen production in human or mouse skeletal muscle.

Aim: AMP-activated protein kinase (AMPK) is activated during cellular energy perturbation. AMPK complexes are composed of three subunits and several variants of AMPK are expressed in skeletal muscle. The regulatory AMPKγ3 subunit is predominantly expressed in fast-twitch muscle fibers.

Association of continuous subcutaneous insulin therapy and diabetic retinopathy in type 1 diabetes: A national cohort study.

Aim: This study aimed to investigate the short-and long-term effect on diabetic retinopathy (DR) in individuals with type 1 diabetes treated with continuous subcutaneous insulin injections (CSII) compared to those using multiple daily injections (MDI).

Methods: We conducted a register-based matched cohort study utilizing data from the Danish Registry of Diabetic Retinopathy as well as several other national Danish health registers. Our cohort consisted of all individuals with type 1 diabetes who attended the Danish screening program for DR from 2013 to 2022.

Vocational functioning in young people accessing services for first-episode psychosis and ultra-high risk of psychosis: A longitudinal naturalistic cohort study.

Aims: Young people with first-episode psychosis (FEP) or at ultra-high risk (UHR) of psychosis often have lower vocational engagement than their peers. This study examines the effect of treatment in early intervention for psychosis services in Australia on engagement in education and employment.

Methods: This is a naturalistic sample of young people aged 12-25 with FEP ( = 1574) and UHR ( = 1515), accessing treatment in the Early Psychosis (hEP) programme.
