Objectives: To explore health professionals' experiences of contested pediatric brain death/death by neurologic criteria (BD/DNC) cases, including factors contributing to conflict, resource needs and utilization, perceived utility of supports available, and case resolution and aftermath.
Design And Methods: Inductive thematic analysis of semistructured interviews with members of the Society of Critical Care Medicine (SCCM) Contestation of Pediatric Brain Death Task Force.
Setting: Ten institutions across seven U.S. states and the District of Columbia.
Participants: Nineteen Task Force members were interviewed in 2023, including pediatric intensivists, neurologists, nurses, respiratory therapists, attorneys, palliative care clinicians, social workers, ethicists, and hospital leadership. Task Force members were recruited primarily because of their experience with contested BD/DNC, although some were recruited because of expertise in other relevant topics, such as communication, information acquisition in BD/DNC, and health equity.
Interventions: None.
Measurements And Main Results: We identified five themes relevant to managing pediatric BD/DNC contestation: 1) personnel to consider involving, including subspecialty consultation, social work, hospital leadership and administration, ethics teams, legal counsel, and security; 2) timelines to maintain, including factors to consider when deciding the most appropriate family accommodations; 3) support for families and patients, including strategies to enhance communication, identifying and mitigating mistrust, and connecting families with support both within and outside the hospital; 4) support for staff, including disseminating information throughout the care team, staff support for one another, and establishing written documentation and policies; and 5) complementary strategies that may augment approaches to BD/DNC contestation, such as policies addressing requests for potentially inappropriate treatment.
Conclusions: Family contestation of pediatric BD/DNC challenges all parties involved. The five themes identified from our qualitative analysis of interviews with experienced professionals do not constitute SCCM clinical practice guidance, but they will be used to inform the development of approaches to BD/DNC contestation through further scholarship and community consultation.

SCN2A gene mutations, which affect the function of the voltage-gated sodium channel NaV1.2, are associated with a spectrum of neurological disorders, including epileptic encephalopathies and autism spectrum disorders. Advanced imaging modalities such as magnetic resonance imaging (MRI) and positron emission tomography (PET) have been instrumental in elucidating the neuroanatomic and functional alterations associated with these mutations.

Sequestration of Plasmodium falciparum-infected erythrocytes (IE) in the microvasculature is a major virulence determinant. While the sequestration of mature stage parasites (trophozoite and schizonts) to vascular endothelium is well established, the conditions that promote ring-stage IE sequestration is less understood. Here, we observed in ring-stage parasites that febrile exposure increased transcript levels of several exported parasite genes involved in the trafficking of the P.

Brain-computer interfaces (BCIs) enable direct communication between the brain and computers. However, their long-term functionality remains limited due to signal degradation caused by acute insertion trauma, chronic foreign body reaction (FBR), and biofouling at the device-tissue interface. To address these challenges, we introduce a multifunctional surface modification strategy called targeting-specific interaction and blocking nonspecific adhesion (TAB) coating for flexible fiber, achieving a synergistic integration of mechanical compliance and biochemical stability.

Primary coenzyme Q (CoQ) deficiency is a mitochondrial disorder with variable clinical presentation and limited response to standard CoQ10 supplementation. Recent studies suggest that 4-hydroxybenzoic acid (4-HBA), a biosynthetic precursor of CoQ, may serve as a substrate enhancement treatment in cases caused by pathogenic variants in COQ2, a gene encoding a key enzyme in CoQ biosynthesis. However, it remains unclear whether 4-HBA is required throughout life to maintain health, whether it offers advantages over CoQ10 treatment, and whether these findings are translatable to humans.

The Sudden Infant Death Syndrome (SIDS) is a major global health problem, with increased risk among socioeconomically disadvantaged populations. We propose SIDS, or a subset, is due to a defect in the brainstem serotonin system mediating cardiorespiratory integration and arousal. This defect impinges on homeostasis during a critical developmental period in infancy, especially in populations experiencing maternal and infantile stress, resulting in sleep-related sudden death.
