Contrast media are an indispensable adjunct to pediatric imaging. The most common include iodine-based contrast media for CT and fluoroscopy, gadolinium-based contrast media and iron-oxide nanoparticles for MRI, and microbubbles for ultrasound. Although many of the considerations in the routine use of contrast media in infants and children (relating for example to renal function, allergic-like reactions, GBCM deposition, and extravasations) are similar to considerations in adult patients, some important differences exist.

Article Synopsis
  • This study aimed to analyze the hemodynamics of a new animal model of Fontan physiology, which is important for understanding poor long-term outcomes in Fontan patients.
  • Researchers created a single-stage Fontan model in juvenile sheep and conducted detailed hemodynamic assessments.
  • Results showed that only a fraction of the sheep survived, with survival rates improving over time due to a learning curve; the study identified key hemodynamic characteristics but noted anatomical differences that affected the model's accuracy, suggesting surgical modifications could enhance future studies.

Article Synopsis
  • Patients with congenital heart disease, particularly those who have undergone the Fontan procedure for single ventricle issues, face a high risk of sudden cardiac events (SCE) and early mortality, highlighting the importance of identifying risk factors.
  • In a study involving 3,132 Fontan patients, 3.5% experienced SCE over an average follow-up of 4 years, with 36% of those cases resulting in death.
  • Key risk factors for SCE included higher NYHA functional class, history of protein-losing enteropathy or plastic bronchitis, large end-diastolic volume index, and reduced ejection fraction, all of which can help in predicting and preventing such events.

Article Synopsis
  • - The study utilized data from the FORCE registry to analyze cardiac magnetic resonance (CMR) metrics in healthier Fontan patients, aiming to create Fontan-specific z-scores that consider different ventricular morphologies.
  • - The "healthier" cohort consisted of 885 patients, primarily children, who were assessed for ventricular size and function against those with adverse outcomes, revealing that those with left ventricle morphology had better metrics.
  • - Comparisons showed adults had lower blood flow in the ascending aorta than children, and patients with adverse outcomes tended to have higher heart volumes and mass, which suggests a link between ventricular morphology and patient prognosis post-Fontan surgery.

Article Synopsis
  • - Large carnivores, like tigers, are vital to ecosystems, but their conservation requires strategies that consider their extensive habitats and behaviors, especially during dispersal phases in human-influenced areas.
  • - A study tracked five tigers from 2009-2020, measuring their movement behaviors with VHF/GPS collars, revealing that tigers traveled significantly farther at night and preferred forested areas over human-populated landscapes.
  • - The research highlighted that lower human disturbance and greater vegetation cover facilitate tiger dispersal, while water availability had no significant effect; it emphasized the need for creating corridors and safe zones to support these animals’ movements.

While molecular adaptations accompanying neuroplasticity during physical exercises are well-established, little is known about adaptations during dysphagia-targeted exercises. This research article has two primary purposes. First, we aim to review the existing literature on the intersection between resistance (strength) training, molecular markers of neuroplasticity, and dysphagia rehabilitation.

Article Synopsis
  • Fontan patients generally have reduced exercise capacity, but some are categorized as high-performing Fontan (HPF) patients with excellent exercise capacity.
  • The study aimed to develop a tool to predict peak oxygen uptake for Fontan patients, explore clinical factors linked to HPF status, and analyze long-term outcomes for these patients.
  • Findings indicated that HPF patients had better left ventricular morphology, were less likely to have certain complications, and had a significantly lower risk of death or needing a heart transplant compared to those with lower exercise capacity.

Background: Driven by habitat loss and fragmentation, large carnivores are increasingly navigating human-dominated landscapes, where their activity is restricted and their behaviour altered. This movement, however, raises significant concerns and costs for people living nearby. While intricately linked, studies often isolate human and carnivore impacts, hindering effective management efforts.

Nicotinamide adenine dinucleotide (NAD) is a redox active molecule that is universally found in biology. Despite the importance and simplicity of this molecule, few reports exist that investigate which molecular features are important for the activity of this ribodinucleotide. By exploiting the nonenzymatic reduction and oxidation of NAD by pyruvate and methylene blue, respectively, we were able to identify key molecular features necessary for the intrinsic activity of NAD through kinetic analysis.

Antimicrobial resistance is a global health threat that requires the development of new treatment concepts. These should not only overcome existing resistance but be designed to slow down the emergence of new resistance mechanisms. Targeted protein degradation, whereby a drug redirects cellular proteolytic machinery towards degrading a specific target, is an emerging concept in drug discovery.
