True cancer stem cells exhibit relative degrees of dormancy and genomic stability.

Background: Cancer stem cells in human tumors have been defined by stem cell markers, embryonal signaling pathways and characteristic biology, ie., namely the ability to repopulate the proliferating population. However, even if these properties can be demonstrated within a tumor cell subpopulation, it does not mean that they are truly hierarchical stem cells because they could have been derived from the proliferating population in a reversible manner.

Pediatric relapsed/refractory ALK+ anaplastic large cell lymphoma treatment and outcomes in the targeted drug era.

Treatment options for patients with relapsed or refractory (R/R) anaplastic large cell lymphoma (ALCL) have increased in the era of targeted therapies such as brentuximab vedotin (BV) and Anaplastic Lymphoma Kinase (ALK) inhibitors. However, there is no standard treatment and limited published data evaluating their use. The goal of this retrospective study is to describe current real-world treatment and outcomes of pediatric, adolescent, and young adult patients with R/R ALK-positive ALCL.

Using Community Engagement to Create a Telecoaching Intervention to Improve Self-Management in Adolescents and Young Adults With Cystic Fibrosis: Qualitative Study.

Background: Adolescents and young adults (AYA) with cystic fibrosis (CF) are at risk for deviating from their daily treatment regimen due to significant time burden, complicated daily therapies, and life stressors. Developing patient-centric, effective, engaging, and practical behavioral interventions is vital to help sustain therapeutically meaningful self-management.

Objective: This study aimed to devise and refine a patient-centered telecoaching intervention to foster self-management in AYA with CF using a combination of intervention development approaches, including an evidence- and theory-based approach (ie, applying existing theories and research evidence for behavior change) and a target population-centered approach (ie, intervention refinement based on the perspectives and actions of those individuals who will use it).

Symptom Documentation in Unstructured Palliative Care Notes of Children and Adolescents with Cancer.

Context: Children and adolescents with cancer experiencing complex symptoms can benefit from subspeciality palliative care. However, standardized methods of symptom documentation by pediatric palliative care teams are lacking. Understanding current approaches to symptom documentation will inform next steps to optimize symptom support.

Objectives: In this study, the authors sought to evaluate substrates for sustained monomorphic VT before TPVR in rTOF.

Methods: Retrospective (2017 to 2021) and prospective (commencing 2021) rTOF patients with native right ventricular outflow tract referred for electrophysiology study (EPS) before TPVR were included.

Practical approach to extracardiac findings in CT and MR for the non-radiologist.

Cross-sectional cardiac imaging plays an essential role in the evaluation of pediatric patients with congenital and acquired heart disease. While the focus of cardiac imaging is primarily on evaluating cardiac structures, it also provides valuable insights into extracardiac structures and associated abnormalities. The radiologists and cardiologists interpreting these exams play a critical role in recognizing these findings and providing recommendations for follow-up testing when indicated.

'Screening should not be based on ability to pay': Australian healthcare providers' and consumers' perspectives on public funding for non-invasive prenatal testing.

Background: Non-invasive prenatal testing (NIPT) does not receive any Medicare rebate. This study investigated the views of Australian healthcare providers and consumers on public funding of NIPT.

Materials And Methods: Two anonymous online, cross-sectional surveys were conducted from September 2022 to January 2023.

Dietary Influences on Gut Microbiota and Their Role in Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD).

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a major contributor to liver-related morbidity, cardiovascular disease, and metabolic complications. Lifestyle interventions, including diet and exercise, are first line in treating MASLD. Dietary approaches such as the low-glycemic-index Mediterranean diet, the ketogenic diet, intermittent fasting, and high fiber diets have demonstrated potential in addressing the metabolic dysfunction underlying this condition.

Attributes of Pediatric Music Therapists: A Qualitative Analysis of Parent Descriptions.

Therapist attributes are known to contribute to positive therapeutic outcomes and are important to effective training and clinical practice. Although well researched in psychology and play therapy, few studies have directly explored music therapist attributes. To explore and understand these descriptions, we conducted a secondary analysis of parent interview data from a multisite trial investigating a music therapist-delivered intervention for young children with cancer and their parents.

The Association of TSLP and IL-4 with Patient-Reported Outcome Measures in Chronic Rhinosinusitis with Nasal Polyps.

Background: Thymic stromal lymphopoietin (TSLP) plays an important role in mediating the type-2-inflammatory response. This study examined how TSLP and interleukin (IL)-4 levels in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) correlated with clinical and postoperative outcomes.

Methods: Solid-phase sandwich ELISA was used to analyze TSLP and IL-4 levels in mucus (n = 47), plasma (n = 17), polyp (n = 30), inferior (n = 25), and middle (n = 26) turbinate tissue collected during functional endoscopic sinus surgery (FESS) in CRSwNP patients (n = 76) and controls (n = 11).

Takotsubo Syndrome Following Catheter Ablation for Atrial Fibrillation: A Systematic Review and Metasummary of Case Reports/Series.

This review synthesizes TTS following AF ablation case reports and series. Until October 2024, PubMed/Medline, SCOPUS, and Google Scholar were searched for AF ablation and TTS case reports and series.

Prevention and Management of Infectious Complications in Pediatric Patients With Cancer: A Survey Assessment of Current Practices Across Children's Oncology Group Institutions.

Introduction: While clinical practice guidelines (CPGs) for pediatric oncology infection prophylaxis and management exist, few data describe actual management occurring at pediatric oncology centers.

Methods: An electronic survey querying infection management practices in nontransplant pediatric oncology patients was iteratively created by the Children's Oncology Group (COG) Cancer Control and Supportive Care Infectious Diseases Subcommittee and sent to leaders at all COG institutions, limiting each site to one response to represent their institution.

Results: The response rate was 57% (129/227 institutions).

Structural polymorphism and diversity of human segmental duplications.

Segmental duplications (SDs) contribute significantly to human disease, evolution and diversity but have been difficult to resolve at the sequence level. We present a population genetics survey of SDs by analyzing 170 human genome assemblies (from 85 samples representing 38 Africans and 47 non-Africans) in which the majority of autosomal SDs are fully resolved using long-read sequence assembly. Excluding the acrocentric short arms and sex chromosomes, we identify 173.

First pass effect in patients with large core infarcts undergoing mechanical thrombectomy: subgroup analysis of the prospective international ASSIST registry.

Background: Studies have described a first pass effect (FPE) where patients with successful recanalization after one pass experience better outcomes. Few studies have evaluated this in patients with large core infarctions.

Objective: To determine whether patients with large core infarcts undergoing mechanical thrombectomy in which first pass reperfusion is achieved experience improved outcomes compared with those who undergo more than one pass.

The use of whole-body MRI (WBMRI) in children, from infancy to adolescence, has expanded rapidly over the past decade, with increasing uptake and a broadening range of clinical indications. Current indications include screening for presymptomatic lesions in cancer predisposition syndromes; tumor staging in known malignancies; investigating fevers of unknown origin; as well as diagnosing and monitoring rheumatologic diseases, vascular anomalies and neuromuscular disorders. This AJR Expert Panel Narrative Review aims to offer a comprehensive discussion of WBMRI in pediatric patients, exploring protocols and other technical considerations, clinical indications, implementation challenges and troubleshooting, as well as controversies in widespread adoption, while considering emerging trends and directions.

The Effect of Resistance and/or Aerobic Training on Quality of Life, Fitness, and Body Composition in Prostate Cancer Patients-A Systematic Review and Meta-Analysis.

: Prostate cancer (PC) and its treatment are often associated with side effects such as fatigue, muscle loss, and diminished quality of life (QoL). Physical exercise, particularly resistance training (RT) and aerobic training (AT), has been suggested as a strategy to mitigate these effects. However, the comparative efficacy of RT, AT, and combined RT/AT on QoL, body composition, physical fitness, and laboratory markers in PC patients is still insufficiently understood.

Acute Necrotizing Pancreatitis Leading to Hemosuccus Pancreaticus and Hemorrhagic Shock in the Setting of Decompensated Cirrhosis.

Hemosuccus pancreaticus (HP) is a rare, life-threatening cause of upper gastrointestinal bleeding, often linked to chronic pancreatitis and pseudoaneurysm rupture into the pancreatic duct. However, its occurrence in acute necrotizing pancreatitis with decompensated cirrhosis is exceedingly rare and poses significant diagnostic and treatment challenges. We report a case of a 34-year-old male with decompensated alcoholic cirrhosis who developed hemorrhagic shock from HP following acute necrotizing pancreatitis.
