Background: Limited research has compared the relative risks and benefits different statins have after heart transplantation (HT).

Method: We hypothesize that higher statin intensity is associated with a smaller degree of allograft intimal thickening on intravascular ultrasound (IVUS) at 1-year post-HT. Allograft intima-media thickness (IMT) on the first annual IVUS was retrospectively compared in patients initiated on a low-intensity statin (pravastatin 20 mg daily) versus moderate-intensity statin (atorvastatin 20 mg daily) post-HT.

Exsolution reactions enable the synthesis of oxide-supported metal nanoparticles, which are desirable as catalysts in green energy conversion technologies. It is crucial to precisely tailor the nanoparticle characteristics to optimize the catalysts' functionality, and to maintain the catalytic performance under operation conditions. We use chemical (co)-doping to modify the defect chemistry of exsolution-active perovskite oxides and examine its influence on the mass transfer kinetics of Ni dopants towards the oxide surface and on the subsequent coalescence behavior of the exsolved nanoparticles during a continuous thermal reduction treatment.

Article Synopsis
  • The study aims to evaluate how effectively the thickness of different macular retinal layers can differentiate glaucomatous eyes and glaucoma suspects from healthy eyes using optical coherence tomography (OCT).
  • The findings reveal that the nerve fiber layer (NFL) and ganglion cell layer (GCL) have the best diagnostic accuracy, with the ganglion cell complex (GCC) performing similarly, while the inner plexiform layer (IPL) is less effective. The combination of NFL or GCL yields the highest sensitivity and overall diagnostic performance.
  • The results underscore the necessity of assessing individual retinal layers rather than relying solely on combined metrics, as the best-performing layers can vary based on the specific area of the retina

The Neuronal alpha-Synuclein Disease (NSD) biological definition and Integrated Staging System (NSD-ISS) provide a research framework to identify individuals with Lewy body pathology and stage them based on underlying biology and increasing degree of functional impairment. Utilizing data from the PPMI, PASADENA, and SPARK studies, we developed and applied biologic and clinical data-informed definitions for the NSD-ISS across the disease continuum. Individuals enrolled as Parkinson's disease, Prodromal, or Healthy Controls were defined and staged based on biological, clinical, and functional anchors at baseline.

Interactions between food and oral anticoagulants (OACs), particularly vitamin K antagonists such as warfarin, are widely recognized and may also be clinically relevant for direct OACs. Pharmacokinetic and pharmacodynamic interactions with food or herbs can lead to anticoagulation potentiation, increased risk of bleeding, or reduced drug efficacy, all compromising patient safety. We conducted a systematic search for randomized controlled trials (RCTs) on PubMed for assessments of interactions between OACs and various ingestants.

Parkinson's disease and dementia with Lewy bodies are currently defined by their clinical features, with α-synuclein pathology as the gold standard to establish the definitive diagnosis. We propose that, given biomarker advances enabling accurate detection of pathological α-synuclein (ie, misfolded and aggregated) in CSF using the seed amplification assay, it is time to redefine Parkinson's disease and dementia with Lewy bodies as neuronal α-synuclein disease rather than as clinical syndromes. This major shift from a clinical to a biological definition of Parkinson's disease and dementia with Lewy bodies takes advantage of the availability of tools to assess the gold standard for diagnosis of neuronal α-synuclein (n-αsyn) in human beings during life.
