Purpose: To evaluate clinical outcomes obtained after cataract surgery involving the implantation of a trifocal hydrophobic intraocular lens (IOL) and to determine if pupil size and the corneal aberrometric profile correlate to visual acuity at different distances.

Methods: 49 patients (98 eyes) underwent bilateral cataract surgery with the placement of FineVision HP IOLs for presbyopia and were assessed at 1- and 3- to 6-months post-surgery. Postoperatively, refraction, monocular and binocular uncorrected and corrected distance visual acuity (UDVA and CDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA) and the binocular defocus curve were measured.

causes devastating rice blast disease, significantly impacting rice production in many countries. Among the many known resistance (R) genes, confers broad-spectrum resistance to isolates and encodes a nucleotide-binding site leucine-rich repeat receptor (NLR). Although Piz-t-interacting proteins and those in the signal transduction pathway have been identified over the last decade, the Piz-t-mediated resistance has not been fully understood at the transcriptomic and metabolomic levels.

Background: There is a substantial population of long-stay patients who non-emergently transfer directly from the neonatal intensive care unit (NICU) to the pediatric intensive care unit (PICU) without an interim discharge home. These infants are often medically complex and have higher mortality relative to NICU or PICU-only admissions. Given an absence of data surrounding practice patterns for non-emergent NICU to PICU transfers, we hypothesized that we would encounter a broad spectrum of current practices and a high proportion of dissatisfaction with current processes.

Article Synopsis
  • Cardiac radioablation (CRA) is an innovative treatment for patients with persistent ventricular tachycardia, but integrating electroanatomic maps into treatment planning is currently challenging due to lack of efficient methods.* -
  • The development of a semi-automated tool called Edico aims to simplify this process by converting electroanatomic maps into a DICOM format, which enhances the accuracy in target volume delineation and boosts workflow efficiency.* -
  • Testing Edico with various electroanatomic maps showed that it effectively maintains essential features during processing, while a sensitivity analysis confirmed optimal voxel sizes to minimize data loss when averaging.*

  • Bicuspid aortic valve (BAV) shows increased progression of aorta dilation compared to tricuspid aortic valve (TAV) in patients with aortic stenosis, with a median annualized change of 0.33 mm/year for BAV versus 0.21 mm/year for TAV.
  • Factors influencing the dilation rate differ by valve type; BAV patients are more affected by low-density lipoprotein (LDL) levels, while TAV patients are influenced by the apolipoprotein B/A-I ratio and baseline aortic jet velocity.
  • The study highlights that men and women have different predictors for AA dilation; men’s dilation relates to baseline jet velocity and aortic diameter, while

Article Synopsis
  • Heart failure (HF) and aortic stenosis (AS) often occur together, complicating treatment due to their related effects on the heart’s function and high rates of serious outcomes.
  • Despite improvements in aortic valve replacement methods, HF is still a major reason patients are rehospitalized and is closely linked to higher mortality rates after surgery.
  • Understanding how HF develops in patients with AS involves studying heart changes caused by the valve's narrowing, the effects of valve replacement, and the role of other health conditions and biomarkers that indicate heart function and risk levels.

DNA hydroxymethylation (5hmC), the most abundant oxidative derivative of DNA methylation, is typically enriched at enhancers and gene bodies of transcriptionally active and tissue-specific genes. Although aberrant genomic 5hmC has been implicated in age-related diseases, its functional role in aging remains unknown. Here, using mouse liver and cerebellum as model organs, we show that 5hmC accumulates in gene bodies associated with tissue-specific function and restricts the magnitude of gene expression changes with age.

Cardiac troponin is extensively used as a biomarker in modern medicine due to its diagnostic capability for myocardial injury, as well as its predictive and prognostic value for cardiac diseases. However, heterophile antibodies, antitroponin antibodies, and macrotroponin complexes can be observed both in seemingly healthy individuals and patients with cardiac diseases, potentially leading to false positive or disproportionate elevation of cTn (cardiac troponin) assay results and introducing discrepancies in clinical interpretations with impact on medical management. In this review article, we describe the possible mechanisms of cTn release and the sources of variations in the assessment of circulating cTn levels.

We report the femtosecond laser writing of meter-long optical waveguides inscribed through the coating of specifically designed optical fibers. In order to improve the material photosensitivity and to ensure non-guiding optical fibers for subsequent laser processing of the waveguiding core, a depressed refractive index core design is implemented by co-doping a large portion of the optical fiber with germanium oxide and fluorine. The enhanced photosensitivity provided by further deuterium loading these fibers allows laser-writing of large refractive index contrast waveguides over wide cross sections.

Magnetic resonance angiography (MRA) performed at ultra-high magnetic field provides a unique opportunity to study the arteries of the living human brain at the mesoscopic level. From this, we can gain new insights into the brain's blood supply and vascular disease affecting small vessels. However, for quantitative characterization and precise representation of human angioarchitecture to, for example, inform blood-flow simulations, detailed segmentations of the smallest vessels are required.

In congenital diaphragmatic hernia (CDH), abdominal organs are displaced into the chest, compress the lungs, and cause mediastinal shift. This contributes to development of pulmonary hypoplasia and hypertension, which is the primary determinant of morbidity and mortality for affected newborns. The severity is determined using prenatal imaging as early as the first trimester and is related to the laterality of the defect, extent of lung compression, and degree of liver herniation.
