Abstract
Chronic kidney disease is a leading cause of death and disability globally and impacts individuals of African ancestry (AFR) or with ancestry in the Americas (AMS) who are under-represented in genome-wide association studies (GWASs) of kidney function. To address this bias, we conducted a large meta-analysis of GWASs of estimated glomerular filtration rate (eGFR) in 145,732 AFR and AMS individuals. We identified 41 loci at genome-wide significance (p < 5 × 10-8), of which two have not been previously reported in any ancestry group. We integrated fine-mapped loci with epigenomic and transcriptomic resources to highlight potential effector genes relevant to kidney physiology and disease, and reveal key regulatory elements and pathways involved in renal function and development. We demonstrate the varying but increased predictive power offered by a multi-ancestry polygenic score for eGFR and highlight the importance of population diversity in GWASs and multi-omics resources to enhance opportunities for clinical translation for all.

Abstract
Rationale Arterial and venous cardiovascular conditions, such as coronary artery disease (CAD), peripheral artery disease (PAD), and venous thromboembolism (VTE), are genetically correlated. Interrogating distinct and overlapping mechanisms may shed new light on disease mechanisms. Objective In this study, we aimed to: identify and compare (1) epidemiologic and (2) causal, genetic relationships between metabolites and CAD, PAD, and VTE. Methods We used metabolomic data from 95,402 individuals in the UK Biobank, excluding individuals with prevalent cardiovascular disease. Logistic regression models adjusted for age, sex, genotyping array, first five principal components of ancestry, and statin use estimated the epidemiologic associations of 249 metabolites with incident CAD, PAD, or VTE. Bidirectional two-sample Mendelian randomization (MR) estimated the causal effects between metabolites and cardiovascular phenotypes using genome-wide association summary statistics for metabolites (N = 118,466 from UK Biobank), CAD (N = 184,305 from CARDIoGRAMplusC4D 2015), PAD (N = 243,060 from Million Veterans Project) and VTE (N = 650,119 from Million Veterans Project). Multivariable MR (MVMR) was performed in subsequent analyses. Results We found that 194, 111, and 69 metabolites were epidemiologically associated (P < 0.001) with CAD, PAD, and VTE, respectively. Metabolomic profiles exhibited variable similarity between disease pairs: CAD and PAD (N = 100 shared associations, R2 = 0.499), CAD and VTE (N = 68, R2 = 0.455), and PAD and VTE (N = 54, R2 = 0.752). MR revealed 28 metabolites that increased risk for both CAD and PAD and 2 metabolites that increased risk for CAD but decreased risk for VTE. Despite strong epidemiologic overlap, no metabolites had a shared genetic relationship between PAD and VTE. MVMR revealed several metabolites with shared causal effects on CAD and PAD related to cholesterol content within very-low-density lipoprotein particles. Conclusions While common arterial and venous conditions are associated with overlapping metabolomic profiles, MR prioritized the role of remnant cholesterol in arterial diseases but not venous thrombosis.

Abstract
BACKGROUND Venous thromboembolism (VTE) is a life-threatening vascular event with environmental and genetic determinants. Recent VTE genome-wide association studies (GWAS) meta-analyses involved nearly 30 000 VTE cases and identified up to 40 genetic loci associated with VTE risk, including loci not previously suspected to play a role in hemostasis. The aim of our research was to expand discovery of new genetic loci associated with VTE by using cross-ancestry genomic resources. METHODS We present new cross-ancestry meta-analyzed GWAS results involving up to 81 669 VTE cases from 30 studies, with replication of novel loci in independent populations and loci characterization through in silico genomic interrogations. RESULTS In our genetic discovery effort that included 55 330 participants with VTE (47 822 European, 6320 African, and 1188 Hispanic ancestry), we identified 48 novel associations, of which 34 were replicated after correction for multiple testing. In our combined discovery-replication analysis (81 669 VTE participants) and ancestry-stratified meta-analyses (European, African, and Hispanic), we identified another 44 novel associations, which are new candidate VTE-associated loci requiring replication. In total, across all GWAS meta-analyses, we identified 135 independent genomic loci significantly associated with VTE risk. A genetic risk score of the significantly associated loci in Europeans identified a 6-fold increase in risk for those in the top 1% of scores compared with those with average scores. We also identified 31 novel transcript associations in transcriptome-wide association studies and 8 novel candidate genes with protein quantitative-trait locus Mendelian randomization analyses. In silico interrogations of hemostasis and hematology traits and a large phenome-wide association analysis of the 135 GWAS loci provided insights to biological pathways contributing to VTE, with some loci contributing to VTE through well-characterized coagulation pathways and others providing new data on the role of hematology traits, particularly platelet function. Many of the replicated loci are outside of known or currently hypothesized pathways to thrombosis. CONCLUSIONS Our cross-ancestry GWAS meta-analyses identified new loci associated with VTE. These findings highlight new pathways to thrombosis and provide novel molecules that may be useful in the development of improved antithrombosis treatments.

Abstract
BACKGROUND When indicated, guidelines recommend measurement of lipoprotein(a) for cardiovascular risk assessment. However, temporal variability in lipoprotein(a) is not well understood, and it is unclear if repeat testing may help refine risk prediction of coronary artery disease (CAD). OBJECTIVES The authors examined the stability of repeat lipoprotein(a) measurements and the association between instability in lipoprotein(a) molar concentration with incident CAD. METHODS The authors assessed the correlation between baseline and first follow-up measurements of lipoprotein(a) in the UK Biobank (n = 16,017 unrelated individuals). The association between change in lipoprotein(a) molar concentration and incident CAD was assessed among 15,432 participants using Cox proportional hazards models. RESULTS Baseline and follow-up lipoprotein(a) molar concentration were significantly correlated over a median of 4.42 years (IQR: 3.69-4.93 years; Spearman rho = 0.96; P < 0.0001). The correlation between baseline and follow-up lipoprotein(a) molar concentration were stable across time between measurements of <3 (rho = 0.96), 3-4 (rho = 0.97), 4-5 (rho = 0.96), and >5 years (rho = 0.96). Although there were negligible-to-modest associations between statin use and changes in lipoprotein(a) molar concentration, statin usage was associated with a significant increase in lipoprotein(a) among individuals with baseline levels ≥70 nmol/L. Follow-up lipoprotein(a) molar concentration was significantly associated with risk of incident CAD (HR per 120 nmol/L: 1.32 [95% CI: 1.16-1.50]; P = 0.0002). However, the delta between follow-up and baseline lipoprotein(a) molar concentration was not significantly associated with incident CAD independent of follow-up lipoprotein(a) (P = 0.98). CONCLUSIONS These findings suggest that, in the absence of therapies substantially altering lipoprotein(a), a single accurate measurement of lipoprotein(a) molar concentration is an efficient method to inform CAD risk.

Abstract
BACKGROUND Racial inequities for patients with heart failure (HF) have been widely documented. HF patients who receive cardiology care during a hospital admission have better outcomes. It is unknown whether there are differences in admission to a cardiology or general medicine service by race. This study examined the relationship between race and admission service, and its effect on 30-day readmission and mortality Methods: We performed a retrospective cohort study from September 2008 to November 2017 at a single large urban academic referral center of all patients self-referred to the emergency department and admitted to either the cardiology or general medicine service with a principal diagnosis of HF, who self-identified as white, black, or Latinx. We used multivariable generalized estimating equation models to assess the relationship between race and admission to the cardiology service. We used Cox regression to assess the association between race, admission service, and 30-day readmission and mortality. RESULTS Among 1967 unique patients (66.7% white, 23.6% black, and 9.7% Latinx), black and Latinx patients had lower rates of admission to the cardiology service than white patients (adjusted rate ratio, 0.91; 95% CI, 0.84-0.98, for black; adjusted rate ratio, 0.83; 95% CI, 0.72-0.97 for Latinx). Female sex and age >75 years were also independently associated with lower rates of admission to the cardiology service. Admission to the cardiology service was independently associated with decreased readmission within 30 days, independent of race. CONCLUSIONS Black and Latinx patients were less likely to be admitted to cardiology for HF care. This inequity may, in part, drive racial inequities in HF outcomes.

Abstract
The ligand-dependent nuclear receptor LXR regulates the expression of genes involved in responses to excess cholesterol including Abca1. Macrophage-specific cholesterol efflux driven by Abca1 has been causally linked to the prevention and reversal of heart disease, but therapeutic strategies for targeting efflux pathways in macrophages have been elusive. Here, we define a novel regulatory axis controlling macrophage responses to cholesterol overload. We identify the lncRNA MeXis as an amplifier of LXR-dependent Abca1 gene transcription in macrophages. MeXis interacts with and guides the promoter binding of nuclear receptor transcriptional coactivators. Loss of MeXis in murine immune cells has a marked impact on chromosome architecture at the Abca1 locus, impairs cellular responses to cholesterol overload, and accelerates the development of atherosclerosis. Our findings identify MeXis as a transcriptional gatekeeper that modifies the actions of LXR in lipid-dependent control of macrophage gene expression. It is conceivable that therapeutic approaches that enhance MeXis activity might augment reverse cholesterol transport and reduce foam cell formation.

Abstract
NAFLD is a common condition linked to obesity, type 2 diabetes, and metabolic syndrome. Simple hepatic steatosis is a risk factor for inflammatory reactions in the liver (NASH), which may lead to cirrhosis. While the mechanism is unclear, NAFLD and NASH are associated with panhypopituitarism, which in the pediatric population often results from craniopharyngioma or pituitary adenoma and the sequelae of treatment, causing hypothyroidism, adrenal insufficiency, hypogonadotropic hypogonadism, and GH deficiency. Refractory NAFLD in panhypopituitarism may be amenable to GH replacement. Here, we report a pediatric case of NASH secondary to panhypopituitarism from craniopharyngioma, which recurred by 11 months after LDLT. Despite low-dose GH replacement, the patient remained GH deficient. Pubertal dosed GH therapy led to rapid and complete resolution of hepatic steatosis, which we tracked using serial 1 H MRS. Pediatric patients with NASH cirrhosis secondary to panhypopituitarism can be good candidates for liver transplantation, but hormone deficiencies predispose to recurrence after transplant. High-dose GH replacement should be considered in pediatric patients with GH deficiency and recurrent disease. A multidisciplinary team approach is essential for successful outcomes.

Abstract
The liver X receptors (LXRs) are members of the nuclear receptor superfamily that regulate sterol metabolism and inflammation. We sought to identify previously unknown genes regulated by LXRs in macrophages and to determine their contribution to atherogenesis. Here we characterize a novel LXR target gene, the lipopolysaccharide binding protein (LBP) gene. Surprisingly, the ability of LXRs to control LBP expression is cell-type specific, occurring in macrophages but not liver. Treatment of macrophages with oxysterols or loading with modified LDL induces LBP in an LXR-dependent manner, suggesting a potential role for LBP in the cellular response to cholesterol overload. To investigate this further, we performed bone marrow transplant studies. After 18 weeks of Western diet feeding, atherosclerotic lesion burden was assessed revealing markedly smaller lesions in the LBP(-/-) recipients. Furthermore, loss of bone marrow LBP expression increased apoptosis in atherosclerotic lesions as determined by terminal deoxynucleotidyl transferase dUTP nick end labeling staining. Supporting in vitro studies with isolated macrophages showed that LBP expression does not affect cholesterol efflux but promotes the survival of macrophages in the setting of cholesterol loading. The LBP gene is a macrophage-specific LXR target that promotes foam cell survival and atherogenesis.

Abstract
Introduction:
The liver X receptors (LXRs) are members of the nuclear receptor superfamily that regulate sterol metabolism and inflammation. Knockout of LXRs in macrophages greatly accelerates the development of atherosclerosis whereas pharmacological LXR activation has potent athero-protective effects. Previous studies have shown that deletion of LXR target genes in hematopoietic cells can have opposing effects on atherosclerosis development. For example, deletion of ABCA1 using bone marrow transfer in atherogenic mouse models showed increases atherosclerotic plaque burden where as knockout studies of ABCG1 and Aim1 decreased lesion formation in bone marrow transplantation experiments owing to an increase in macrophage apoptosis.
Rationale:
We sought to identify previously unknown genes regulated by LXRs in macrophages and to determine their contribution to atherogenesis.
Methods & Results:
We demonstrate that the lipopolysaccharide binding protein (LBP), a secreted glycoprotein, is an LXR target gene in macrophages. Treatment of mouse peritoneal macrophages with modified LDL or oxysterols induces LBP expression, an effect that was lost in LXRαβ-/- macrophages, consistent with a role for LBP in the cellular response to cholesterol overload. To investigate this further, we performed bone marrow transplant studies using WT or LBP-/- donors and LDLR-/- recipients. After 18 weeks of western diet feeding atherosclerotic lesion burden was assessed by en face and aortic root section analysis. LDLR-/- mice receiving LBP-/- bone marrow had markedly smaller lesions compared to those receiving WT (P<0.0001 in en face analysis; P<.01 in root section analysis). Furthermore, loss of bone marrow LBP expression led to a strong increase in apoptosis in atherosclerotic lesions as determined by TUNEL staining. In vitro studies with isolated macrophages and stable cell lines showed that LBP expression does not affect cholesterol efflux but promotes the survival of macrophages in the setting of cholesterol loading.
Conclusions:
The LBP gene is a macrophage LXR target that promotes foam cell survival and atherogenesis. Our study identifies LBP as a potential diagnostic and therapeutic target in human cardiovascular disease.

Abstract
Since the first tissue-engineered vascular graft (TEVG) was implanted in a child over a decade ago, growth in the field of vascular tissue engineering has been driven by clinical demand for improved vascular prostheses with performance and durability similar to an autologous blood vessel. Great strides were made in pediatric congenital heart surgery using the classical tissue engineering paradigm, and cell seeding of scaffolds in vitro remained the cornerstone of neotissue formation. Our second-generation bone marrow cell-seeded TEVG diverged from tissue engineering dogma with a design that induces the recipient to regenerate vascular tissue in situ. New insights suggest that neovessel development is guided by cell signals derived from both seeded cells and host inflammatory cells that infiltrate the graft. The identification of these signals and the regulatory interactions that influence cell migration, phenotype and extracellular matrix deposition during TEVG remodeling are yielding a next-generation TEVG engineered to guide neotissue regeneration without the use of seeded cells. These developments represent steady progress towards our goal of an off-the-shelf tissue-engineered vascular conduit for pediatric congenital heart surgery.

Abstract
BACKGROUND Multiple nonrandomized studies demonstrate the accuracy of computed tomography (CT) scan in diagnosing appendicitis. This study compared CT scan with standard management in diagnosing appendicitis. METHODS This was a prospective randomized study of patients who received general surgery consultation for appendicitis. Patients were randomized to receive CT scan or standard management. RESULTS There were 65 patients in the CT scan group and 63 patients in the standard management group. The sensitivity, specificity, and accuracy of CT scan were 94%, 100%, and 96%, respectively. CT scan positively altered the management in 26% and made alternative diagnoses in 14%. The sensitivity, specificity, and accuracy of the standard management group were 100%, 79%, and 89%, respectively. The standard management group had a negative appendectomy rate of 19%. CONCLUSION CT scan with rectal contrast is an effective method for diagnosing appendicitis and should be performed in all patients suspected of having appendicitis.

Abstract
Leukocyte migration inhibition (LMI) is a widely used in vitro correlate of delayed type hypersensitivity (DTH) in mammals. This report describes the development of a direct agarose LMI assay for studying DTH in avian species. Optimum demonstration of LMI was found with leukocytes isolated on a Ficoll-diatrizoate gradient solution. The agarose culture plates were maintained at pH 7.2-7.4 in a water-vapor saturated, 39 degrees C. incubator with 2% CO2 tension. Antigen specific LMI was demonstrated in chickens with DTH to purified protein derivative of Mycobacterium (PPD) and ferritin. A good comparison between LMI and DTH, as measured by the delayed wattle reaction (DWR), was demonstrated. The effect of bacterial lipopolysaccharide (LPS) on LMI was examined and LPS in microgram quantities was found to inhibit in vitro migration of chicken leukocytes. Contamination of antigen preparations with LPS is a probable explanation for occasional nonspecific inhibition of leukocyte migration since endotoxin is an almost ubiquitous contaminant of antigen preparations.

Abstract
The effect of chlordecone on the mouse brain synaptosomal Na+-K+ ATPase, Mg2+ ATPase and p-nitrophenyl phosphatase (PNPPase) activities was determined. In addition, the effect of chlordecone on [3H] ouabain binding to synaptosomes was also investigated. The in vitro data show that chlordecone inhibits PNPPase, Na+-K+ ATPase, and Mg2+ ATPase activities with ID50 values of 4, 5 and 7 micrograms respectively. Treatment of mice with symptomatogenic doses of chlordecone resulted in a decreased synaptosomal Na+-K+ and oligomycin-sensitive (mitochondrial) Mg2+ ATPases. The decrease was dose-dependent. The oligomycin-insensitive Mg2+ ATPase activity was unaffected either in vitro or in vivo. The binding of [3H] ouabain to synaptosomal membranes was inhibited by chlordecone in a dose-dependent manner in both in vitro and in vivo experiments. The binding of [14C] chlordecone to synaptosomes occurs even at nanomolar concentrations. The marked inhibition of brain synaptosomal ATPases and ouabain binding by chlordecone suggests that chlordecone may impair active transport mechanisms in synaptosomal membranes.
