Although indications for a Fontan procedure have broadened, some patients, in the past, were ineligible for the Fontan completion after a Glenn procedure and thus suffered the limitations of the Glenn procedure-namely desaturation, arrhythmia and reduced quality of life. If examined more closely, however, completion may yet be feasible for such patients. We present here a complex case of asplenia, dextrocardia and total anomalous pulmonary venous return (1b) where the Fontan procedure was successfully completed 12 years after the Glenn procedure. A unique surgical strategy incorporating intra-atrial total cavopulmonary connection and atrioventricular valve repair contributed to our success.

In much of the northern Great Basin of the western United States, rangelands, and semi-arid ecosystems invaded by exotic annual grasses such as cheatgrass () and medusahead () are experiencing an increasingly short fire cycle, which is compounding and persistent. Improving and expanding ground-based field methods for measuring the above-ground biomass (AGB) may enable more sample collections across a landscape and over succession regimes and better harmonize with other remote sensing techniques. Developments and increased adoption of unoccupied aerial systems (UAS) and instrumentation for vegetation monitoring enable greater understanding of vegetation in many ecosystems.

Objective: Despite the well-established increased risk of cardiovascular mortality in individuals with bipolar disorder (BD), prevention and treatment of cardiovascular risk factors and diseases have been largely overlooked in this population. This manuscript reviews the pathophysiological basis of the connection between BD and cardiovascular diseases, highlighting their shared mechanisms, reciprocal interactions, and relevant prevention and treatment strategies.
Methods: For this narrative review, a search was carried out on PubMed using the keywords bipolar disorder, cardiovascular diseases, and cardiovascular risk factors.

Background: There is a paucity of evidence on the association between genetic propensity for hippocampal atrophy with cognitive outcomes. Therefore, we examined the relationship of the polygenic risk score for hippocampal atrophy (PRShp) with the incidence of amnestic mild cognitive impairment (aMCI) and Alzheimer's disease (AD) as well as the rates of cognitive decline.
Methods: Participants were drawn from the population-based HELIAD cohort.

Cis-regulatory elements (CREs) control gene expression and are dynamic in their structure and function, reflecting changes in the composition of diverse effector proteins over time. However, methods for measuring the organization of effector proteins at CREs across the genome are limited, hampering efforts to connect CRE structure to their function in cell fate and disease. Here we developed PRINT, a computational method that identifies footprints of DNA-protein interactions from bulk and single-cell chromatin accessibility data across multiple scales of protein size.

The field of artificial intelligence (AI) has entered a new cycle of intense opportunity, fueled by advances in deep learning, including generative AI. Applications of recent advances affect many aspects of everyday life, yet nowhere is it more important to use this technology safely, effectively, and equitably than in health and health care. Here, as part of the National Academy of Medicine's Vital Directions for Health and Health Care: Priorities for 2025 initiative, which is designed to provide guidance on pressing health care issues for the incoming presidential administration, we describe the steps needed to achieve these goals.
