    Abstract Background: The development of modern antiviral therapy for hepatitis C virus (HCV) has allowed for the transplantation of HCV nucleic acid amplification testing-positive (NAT+) donor lungs with acceptable short-term outcomes. We sought to evaluate trends and midterm outcomes of lung transplant recipients of HCV NAT+ donor allografts.
    Methods: All adults undergoing isolated lung transplantation in the United Network for Organ Sharing database from January 2016 to December 2022 were included in the study. Lung transplant recipients were stratified based on donor HCV status (HCV NAT+ vs NAT-). Propensity score matching was used to adjust for differences between groups. Several outcomes, including acute rejection by 1 year, early (30-day and in-hospital) mortality, and both 1- and 3-year survival, were compared between matched groups.
    Results: A total of 16,725 patients underwent lung transplantation during the study period, with 489 (3%) receiving HCV NAT+ donor lungs. Regions 1 (18%) and 6/8 (both 0%) had the highest and lowest proportions, respectively, of HCV NAT+ donor transplants. Utilization of HCV NAT+ donors increased throughout the study period from 2 (0.1%) in 2016 to a peak of 117 (5%) in 2019. Donors who were HCV NAT+ were younger (34 vs 36 years, p < 0.001), more often female (44% vs 39%, p < 0.01), and more commonly died due to drug intoxication (56% vs 15%, p < 0.001). Recipients of HCV NAT+ donor lungs were similar in age (62 vs 62 years, p = 0.69) and female gender (43% vs 39%, p = 0.15) but had lower lung allocation scores (38 vs 41, p < 0.001) compared to others. Rates of acute rejection (13% vs 17%, p = 0.09), early mortality (30-day: 2% vs 1%, p = 0.59, in-hospital: 3% vs 4%, p = 0.38), as well as 1-year (90% vs 92%, p = 0.29) and 3-year survival (69% vs 75%, p = 0.13) were not significantly different between matched groups.
    Conclusions: Lung transplant recipients of HCV NAT+ donor allografts experience similar rates of acute rejection, early mortality, and 3-year survival compared to all other lung recipients. Increased use of HCV NAT+ donor allografts may help to expand the donor pool and alleviate donor shortages.

    Abstract Lipoic acid is an essential sulfur-containing cofactor used by several multienzyme complexes involved in energy metabolism and the breakdown of certain amino acids. It is composed of n-octanoic acid with sulfur atoms appended at C6 and C8. Lipoic acid is biosynthesized de novo in its cofactor form, in which it is covalently bound in an amide linkage to a target lysyl residue on a lipoyl carrier protein (LCP). The n-octanoyl moiety of the cofactor is derived from type 2 fatty acid biosynthesis and is transferred to an LCP to afford an octanoyllysyl amino acid. Next, lipoyl synthase (LipA in bacteria) catalyzes the attachment of the two sulfur atoms to afford the intact cofactor. LipA is a radical S-adenosylmethionine (SAM) enzyme that contains two [4Fe-4S] clusters. One [4Fe-4S] cluster is used to facilitate a reductive cleavage of SAM to render the highly oxidizing 5'-deoxyadenosyl 5'-radical needed to abstract C6 and C8 hydrogen atoms to allow for sulfur attachment. By contrast, the second cluster is the sulfur source, necessitating its destruction during turnover. In Escherichia coli, this auxiliary cluster can be restored after each turnover by NfuA or IscU, which are two iron-sulfur cluster carrier proteins that are implicated in iron-sulfur cluster biogenesis. In this chapter, we describe methods for purifying and characterizing LipA and NfuA from Mycobacterium tuberculosis, a human pathogen for which endogenously synthesized lipoic acid is essential. These studies provide the foundation for assessing lipoic acid biosynthesis as a potential target for the design of novel antituberculosis agents.

    Abstract Patients with bicuspid aortic valves commonly require an intervention on their valve and/or aorta. Because of their heterogeneous presentations, recommendations for imaging surveillance and surgery timing are highly individualized. Critical points in care include time of diagnosis, transition from adolescent to adult medicine, and surgery referral. To better support patients with bicuspid aortic valves, we developed a comprehensive program that utilizes the multidisciplinary care team, complex interventions, and translational research protocols. We describe our program structure and experience with this common and sometimes challenging diagnosis.

    Abstract Foraging theory predicts which prey patches predators should target. However, in most habitats, what constitutes a 'patch' and how prey density is calculated are subjective concepts and depend on the spatial scale at which the predator (or scientist) is observing. Moreover, the predator's 'foraging scale' affects prey population dynamics: predators should produce directly density-dependent (DDD) prey mortality at the foraging scale, but inversely density-dependent (IDD) mortality (safety-in-numbers) at smaller scales. We performed the first experimental test of these predictions using behavioral assays with guppies (Poecilia reticulata) feeding on bloodworm 'prey' patches. The guppy's foraging scale had already been estimated in a prior study. Our experimental results confirmed theoretical predictions: predation was IDD when prey were aggregated at a scale smaller than the foraging scale, but not when prey were aggregated at larger scales. These results could be used to predict outcomes of predator-prey interactions in continuous, non-discrete habitats in the field.

    Abstract Novel low-pressure irrigation technologies have been widely adopted by farmers, allowing both reduced water and energy use. However, little is known about how the transition from legacy technologies affected water and energy use at the aquifer scale. Here, we examine the widespread adoption of low-energy precision application (LEPA) and related technologies across the Kansas High Plains Aquifer. We combine direct energy consumption and carbon emission estimates with life cycle assessment to calculate the energy and greenhouse gas (GHG) footprints of irrigation. We integrate detailed water use, irrigation type, and pump energy source data with aquifer water level and groundwater chemistry information to produce annual estimates of energy use and carbon emissions from 1994 to 2016. The rapid adoption of LEPA technologies did not slow pumping, but it reduced energy use by 19.2% and GHG emissions by 15.2%. Nevertheless, water level declines have offset energy efficiency gains because of LEPA adoption. Deeper water tables quadrupled the proportion of GHG emissions resulting from direct carbon emissions, offsetting the decarbonization of the regional electrical grid. We show that low-pressure irrigation technology adoption, absent policies that incentivize or mandate reduced water use, ultimately increases the energy and carbon footprints of irrigated agriculture.

    Abstract When tissue biopsy is not medically prudent or tissue is insufficient for molecular testing, alternative methods are needed. Because cell-free DNA (cfDNA) has been shown to provide a representative surrogate for tumor tissue, we sought to evaluate its utility in this clinical scenario. cfDNA was isolated from the plasma of patients and assayed with low-coverage (∼0.3×), genome-wide sequencing. Copy-number alterations (CNA) were identified and characterized using analytic methods originally developed for noninvasive prenatal testing (NIPT) and quantified using the genomic instability number (GIN), a metric that reflects the quantity and magnitude of CNAs across the genome. The technical variability of the GIN was first evaluated in an independent cohort comprising genome-wide sequencing results from 27,754 women who consented to have their samples used for research and whose NIPT results yielded no detected CNAs to establish a detection threshold. Subsequently, cfDNA sequencing data from 96 patients with known cancers but for whom a tissue biopsy could not be obtained are presented. An elevated GIN was detected in 35% of patients and detection rates varied by tumor origin. Collectively, CNAs covered 96.6% of all autosomes. Survival was significantly reduced in patients with an elevated GIN relative to those without. Overall, these data provide a proof of concept for the use of low-coverage, genome-wide sequencing of cfDNA from patients with cancer to obtain relevant molecular information in instances where tissue is difficult to access. These data may ultimately serve as an informative complement to other molecular tests.

    Abstract Viremia in the vertebrate host is a major determinant of arboviral reservoir competency, transmission efficiency, and disease severity. However, immune mechanisms that control arboviral viremia are poorly defined. Here, we identify critical roles for the scavenger receptor MARCO in controlling viremia during arthritogenic alphavirus infections in mice. Following subcutaneous inoculation, arthritogenic alphavirus particles drain via the lymph and are rapidly captured by MARCO+ lymphatic endothelial cells (LECs) in the draining lymph node (dLN), limiting viral spread to the bloodstream. Upon reaching the bloodstream, alphavirus particles are cleared from the circulation by MARCO-expressing Kupffer cells in the liver, limiting viremia and further viral dissemination. MARCO-mediated accumulation of alphavirus particles in the draining lymph node and liver is an important host defense mechanism as viremia and viral tissue burdens are elevated in MARCO

    Abstract The conversion of 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC) is a key step in DNA demethylation that is mediated by ten-eleven translocation (TET) enzymes, which require ascorbate/vitamin C. Here, we report the 5hmC landscape of normal hematopoiesis and identify cell type-specific 5hmC profiles associated with active transcription and chromatin accessibility of key hematopoietic regulators. We utilized CRISPR/Cas9 to model TET2 loss-of-function mutations in primary human hematopoietic stem and progenitor cells (HSPC). Disrupted cells exhibited increased colonies in serial replating, defective erythroid/megakaryocytic differentiation, and in vivo competitive advantage and myeloid skewing coupled with reduction of 5hmC at erythroid-associated gene loci. Azacitidine and ascorbate restored 5hmC abundance and slowed or reverted the expansion of TET2-mutant clones in vivo. These results demonstrate the key role of 5hmC in normal hematopoiesis and TET2-mutant phenotypes and raise the possibility of utilizing these agents to further our understanding of preleukemia and clonal hematopoiesis.
    Significance: We show that 5-hydroxymethylation profiles are cell type-specific and associated with transcriptional abundance and chromatin accessibility across human hematopoiesis. TET2 loss caused aberrant growth and differentiation phenotypes and disrupted 5hmC and transcriptional landscapes. Treatment of TET2 KO HSPCs with ascorbate or azacitidine reverted 5hmC profiles and restored aberrant phenotypes. This article is highlighted in the In This Issue feature, p. 265.
