Abstract
BACKGROUND Genetic mutations in beta-glucocerebrosidase (GBA) represent the major genetic risk factor for Parkinson's disease (PD). GBA participates in both the endo-lysosomal pathway and the immune response, two important mechanisms involved in the pathogenesis of PD. However, modifiers of GBA penetrance have not yet been fully elucidated. METHODS We characterized the transcriptomic profiles of circulating monocytes in a population of patients with PD and healthy controls (CTRL) with and without GBA variants (n = 23 PD/GBA, 13 CTRL/GBA, 56 PD, 66 CTRL) and whole blood (n = 616 PD, 362 CTRL, 127 PD/GBA, 165 CTRL/GBA). Differential expression analysis, pathway enrichment analysis, and outlier detection were performed. Ultrastructural characterization of isolated CD14+ monocytes in the four groups was also performed through electron microscopy. RESULTS We observed hundreds of differentially expressed genes and dysregulated pathways when comparing manifesting and non-manifesting GBA mutation carriers. Specifically, when compared to idiopathic PD, PD/GBA showed dysregulation in genes involved in alpha-synuclein degradation, aging and amyloid processing. Gene-based outlier analysis confirmed the involvement of lysosomal, membrane trafficking, and mitochondrial processing in manifesting compared to non-manifesting GBA-carriers, as also observed at the ultrastructural levels. Transcriptomic results were only partially replicated in an independent cohort of whole blood samples, suggesting cell-type specific changes. CONCLUSIONS Overall, our transcriptomic analysis of primary monocytes identified gene targets and biological processes that can help in understanding the pathogenic mechanisms associated with GBA mutations in the context of PD.

Abstract
In southwest Florida, Karenia brevis (K. brevis) blooms occur frequently, can be very intense and persist over several years. Individuals living in coastal communities around the Gulf of Mexico are particularly vulnerable to brevetoxins released by K. brevis in seawater and carried inland within marine aerosol. Exposure to K. brevis occurs during residential, recreational, and occupational activities and has been associated with upper respiratory tract (URT) symptoms in healthy and medically vulnerable individuals. Additionally, ingestion of brevetoxin-contaminated seafood causes neurotoxic shellfish poisoning (NSP), and severe headaches prompting emergency department visits which occur in excess during K. brevis blooms. The current study examined a dose-response relationship between K. brevis in coastal waters and URT and NSP-like symptoms and headaches among southwest Florida residents. Data on past medical history (PMH) and medical symptoms were collected from the participants (n = 258) in five southwest Florida counties between June 2019 to August 2021. A dose-response relationship was observed between K. brevis blooms and reporting of URT and NSP-like symptoms and headaches. Reporting of NSP-like symptoms was higher among participants with a PMH of migraines, chronic fatigue syndrome (CFS) and mild memory loss, while the association of headaches with K. brevis blooms was accentuated among individuals with a PMH of migraines. These results suggest further investigations into the threshold of aerosolized brevetoxin dose required to elicit URT, headaches and/or NSP-like symptoms. These symptoms ultimately cause significant public health safety concerns, primarily among vulnerable populations with preexisting neurological conditions.

Abstract
BackgroundPatients’ post-operative satisfaction with their hospital experience is important to patient care, hospital reimbursement, and comparison between hospitals. The Press Ganey (PG) inpatient survey is commonly administered to assess patient satisfaction with the process of care. However, whether patient PG survey scores following primary unilateral hip and knee arthroplasty are associated with a patient’s race and socioeconomic status (SES) is unknown.ObjectivesWe aimed to determine whether patient PG survey overall assessment scores differ by race and SES.MethodsWe linked data for patients in large institutional hip and knee arthroplasty registries consisting of surgeries from July 2010–February 2012 to their PG survey responses. Patients undergoing primary unilateral surgery of Black or White race who resided in New York, New Jersey, or Connecticut at the time of surgery were included in the analysis. The primary outcome variable was the PG overall assessment score, calculated as the mean of a patient’s ratings for the three questions in the “Overall Assessment” section of the PG survey and dichotomized as either completely satisfied (score of 100) or not completely satisfied (score <100). Primary payor was used as a proxy for patient SES. Multivariable logistic regression was performed for the hip and knee cohorts separately to determine if patient race and primary payor were associated with not being completely satisfied, adjusting for age, sex, and American Society of Anesthesiology (ASA) score.ResultsThere were 2,516 hip patients and 2,113 knee patients with PG overall assessment scores included in the analyses (Table 1). Black patients were more likely to be not completely satisfied compared to White patients in both cohorts [hip (odds ratio (OR)=1.64; 95% confidence interval (CI): 1.03, 2.61; p=0.04)]; [knee (OR=1.83; 95% CI: 1.16, 2.88; p=0.01). In the hip cohort, patients between 70-79 years old (OR=1.71; 95% CI: 1.09, 2.67; p=0.02) and older than 80 years (OR=2.00; 95% CI: 1.20, 3.32; p<0.01) were more likely to be not completely satisfied. In the knee cohort, patients 50-59 years old (OR=0.56; 95% CI: 0.33, 0.97; p=0.04) and 60-69 years old (OR=0.57; 95% CI: 0.33, 0.96; p=0.03) were less likely to be not completely satisfied compared to patients <50 years old.Table 1.Likelihood of not being completely satisfied with the process of care (PG score <100)VariableReferenceCategoryHip Cohort (n = 2,516)Knee Cohort (n = 2,113)Odds Ratio95% CIp-valueOdds Ratio95% CIp-valueAge Group<5050-591.02(0.69, 1.50)0.9390.56(0.32, 0.97)0.039<5060-691.04(0.70, 1.54)0.8580.57(0.33, 0.96)0.034<5070-791.71(1.09, 2.67)0.0190.63(0.36, 1.11)0.113<5080+2.00(1.20, 3.32)0.0080.97(0.53, 1.77)0.912SexFemaleMale0.84(0.69, 1.02)0.0821.03(0.83, 1.26)0.816RaceWhiteBlack1.64(1.03, 2.61)0.0381.83(1.16, 2.88)0.010ASA status121.04(0.70, 1.55)0.8321.23(0.60, 2.51)0.580131.45(0.91, 2.29)0.1161.36(0.64, 2.87)0.41914<0.01(0.00, ***)0.968<0.01(0.00, ***)0.977Primary PayorMedicareMedicaid1.35(0.26, 7.01)0.718<0.01(0.00, ***)0.983MedicareOther/Unknown1.24(0.94, 1.64)0.1260.87(0.65, 1.17)0.362MedicarePrivate1.13(0.61, 2.10)0.6881.01(0.57, 1.78)0.983ASA = American Society of Anesthesiologist (ASA) physical status classification.

Abstract
Microglia have emerged as important players in brain aging and pathology. To understand how genetic risk for neurological and psychiatric disorders is related to microglial function, large transcriptome studies are essential. Here, we describe the transcriptome analysis of 255 primary human microglia samples isolated at autopsy from multiple brain regions of 100 human subjects. We performed systematic analyses to investigate various aspects of microglial heterogeneities, including brain region and aging. We mapped expression and splicing quantitative trait loci and showed that many neurological disease susceptibility loci are mediated through gene expression or splicing in microglia. Fine-mapping of these loci nominated candidate causal variants that are within microglia-specific enhancers, finding associations with microglia expression of USP6NL for Alzheimer’s disease and P2RY12 for Parkinson’s disease. We have built the most comprehensive catalog to date of genetic effects on the microglia transcriptome and propose candidate functional variants in neurological and psychiatric disorders.

Abstract
PURPOSE The aim of this article was to validate the Spanish version of the Home Environment Survey (HES-S) and was divided in two studies: (1) to assess the reliability, convergent validity of HES-S in a survey of 145 parents of children with overweight/obesity; (2) to study the magnitude of the association between children's BMI status with the latent scores theoretically defined by the HES model. METHODS To test the scale and the model, a confirmatory factor analysis (CFA) and a path analysis were carried out among a sample of 156 parents of preadolescents (106 overweight/obesity and 50 normal-weight children). No CFA or EFA were carried out in the validation of the original instrument. RESULTS Study 1, both the Physical Activity and the Eating Habits components of the scale showed adequate levels of internal consistency for the majority of the scales, except for two. One of them, Healthy Eating Parental Policies (HEP) subscale was reduced after excluded two items, although it did not improve substantially. This model indicated that there was a significant association between the two Eating Habits scales and the child's weight status, but child's weight was not associated with the Physical Activity components. Convergent validity was confirmed by correlations with related variables: family eating habits (F-EAT), parent's physical activity (IPAQ), and children's physical activity (assessed via accelerometers during one week). Study 2, our results replicated the original four factor structure proposed for physical activity (CFI = 0.99; RMSEA = 0.03), but the original factor structure of the eating habits component was not supported. In addition, the relationship of the child's weight status, the Physical Activity components, and the two scales of Eating Habits (Parental Modeling and Policies) was explored with a path analysis showing good fit indices (CFI = 0.95; RMSEA = 0.06). Child's BMI was negatively associated with Healthy Eating Parental Role Modeling (r = - 0.21) and with Healthy Eating Parental Policies (r = - 0.19), but not with the factors of Child's Physical Activity model. CONCLUSION To our knowledge, this is the first instrument to assess obesogenic family environment in Spanish speaking countries, which is a relevant dimension within a health perspective so as to implement new policies and strategies in obesity tertiary prevention. Overall, the confirmatory factor analysis of the HES-S has only provided additional support for one part related to Physical Activity. In addition, Child's BMI was correlated with scales of Eating Habits but not with Child's Physical Activity factor. These results clearly suggest that further research is warranted. LEVEL III Case-control analytic study.

Abstract
An increasing number of identified Parkinson's disease (PD) risk loci contain genes highly expressed in innate immune cells, yet their role in pathology is not understood. We hypothesize that PD susceptibility genes modulate disease risk by influencing gene expression within immune cells. To address this, we have generated transcriptomic profiles of monocytes from 230 individuals with sporadic PD and healthy subjects. We observed a dysregulation of mitochondrial and proteasomal pathways. We also generated transcriptomic profiles of primary microglia from brains of 55 subjects and observed discordant transcriptomic signatures of mitochondrial genes in PD monocytes and microglia. We further identified 17 PD susceptibility genes whose expression, relative to each risk allele, is altered in monocytes. These findings reveal widespread transcriptomic alterations in PD monocytes, with some being distinct from microglia, and facilitate efforts to understand the roles of myeloid cells in PD as well as the development of biomarkers.

Abstract
Background:Total knee arthroplasty (TKA) outcomes are linked to surgical volume,1 despite the increase in TKA utilization, racial disparities in TKA outcomes persist. Blacks in the US are at a higher risk of aseptic revision of TKA (R-TKA) when compared to Whites, yet the reasons for this are not understood.Objectives:The objective of this study is to examine the relationship between hospital and surgeon annual TKA volume and R-TKA outcomes by race.Methods:This is an observational cohort study. New York Statewide Planning and Research Cooperative System data for 2004 – 2013 was used to identify patients who underwent primary TKA. Data through 2015 was used to identify R-TKA within 2 years of the index TKA. Hospital characteristics were obtained from the AHA Annual Survey. Surgeon data was collected from New York State Education Department and New York State Physician Profile. Surgeon annual TKA volume was categorized based on cutoffs established by Wilson et al1 as </=12, 13-59, 60-145 or >/= 146, and hospital TKA volume as </=89, 90-235, 236-644 and >/=645. We calculated the odds of R-TKA in Whites and Blacks separately and generated crude odds ratios (OR) comparing Blacks to Whites to examine trends across volume categories. A multivariable logistic regression model adjusted for known R-TKA risk factors was also performed.Results:A total of 163,576 patients were included. Mean (SD) age was 66.4 (10.4) years, 107,233 (65.6%) were female, 124,277 (76.6%) were White and 15,990 (9.8%) were Black. 2925 patients underwent aseptic R-TKA. In logistic regression analysis, Blacks had a higher risk of R-TKA (OR 1.42, 95%CI 1.26-1.6) (Table 1). Risk of R-TKA was also higher when surgeon annual volume was </=12 (OR 1.5, 95%CI 1.25-1.8) or 13-59 (OR 1.16, 95%CI 1.04-1.29) TKA compared to the highest volume surgeons (>/=146). Patients who had surgery at a hospital with annual volume of 236-634 TKA were less likely to undergo R-TKA compared to the highest volume hospitals (>/=645) (OR 0.88, 95%CI 0.79-0.98). Other risk factors for R-TKA were younger age and worker’s compensation, while patients with inflammatory arthritis had a lower risk. Figures 1A and 1B show the odds of R-TKA in Whites and Blacks, respectively, by hospital and surgeon volume. Figure 1C shows the crude OR for Blacks to Whites for each category pair. The OR ranged from 0.9 to 2.5, with the largest disparity found in patients who have TKA performed by surgeons with 60-145 annual TKA volume at the highest volume hospitals (>/=645).Conclusion:Patients having TKA by a surgeon performing <60 TKA per year have higher risk of R-TKA. Racial disparities in R-TKA risk are highest for TKA by surgeons performing 60-145 TKA per year at hospitals performing >/=645 TKA per year. Future studies should examine factors, such as whether trainees are involved the surgery, that may vary based on social determines of health, such as patient race and payor.References:[1]Wilson S. et al Meaningful thresholds for the volume-outcome relationship in total knee arthroplasty.

Abstract
Background:Black people are less likely to undergo total joint arthroplasties, despite reporting more severe symptoms. (1) While racial disparities exist in treatment utilization for osteoarthritis, comprehensive studies of the treatment preferences of Black people have not been conducted.Objectives:The purpose of this manuscript is to systematically review the literature and identify Black osteoarthritis patients’ treatment preferences to understand how they may contribute to racial differences in the utilization of different treatment options.Methods:Searches ran on April 8, 2019 and April 7, 2020 in the following databases: Ovid MEDLINE (ALL - 1946 to Present); Ovid EMBASE (1974 to present); and The Cochrane Library (Wiley). Using the Patient/Population-Intervention-Comparison/Comparator-Outcome (PICO) format, our population of interest was Black people with hip and/or knee osteoarthritis, our intervention was preferences and opinions about treatment options for osteoarthritis, our comparator was white people with hip and/or knee osteoarthritis, and our outcome was preferences of osteoarthritis therapies. The protocol was registered under the PROSPERO international register, and the Preferred Reporting Items of Systematic reviews and Meta-Analyses (PRISMA) guidelines were followed.Results:Searches across the chosen databases retrieved 10,894 studies after de-duplication, 182 full text, and 31 selected for inclusion in this review. Black people were less likely to use NSAIDs or narcotic analgesics compared to white people. (Figure 1) Black people were more likely than white people to use spirituality and prayer, as well as topical treatments. Utilization of meditation, supplement/vitamin use, and hot/cold treatments was not significantly different between groups. Black people were less willing than white people to consider or undergo joint replacements, even if the procedure was needed and recommended by a physician.Conclusion:Racial differences persist in OA care across the spectrum of options.

Abstract
Background:A third of knee osteoarthritis presents with bilateral symptomatic arthritis. In these patients, treatment options include either a staged Unilateral Total knee arthroplasty (UTKA) procedure, or a simultaneous Bilateral TKA (BTKA) procedure. Even though literature regarding outcomes in BTKA procedure has not consistently been favorable, it remains popular in select patients due to use of a single anesthetic, shorter overall surgical time, lower cost and lower overall use of narcotics. African Americans (AAs) have lower utilization and worse outcomes in UTKA literature. It is unclear whether these racial variations extend to BTKA.Objectives:We sought to examine BTKA vs UTKA utilization rates and outcomes comparing AA and White patients.Methods:National Inpatient Sample (NIS) - Healthcare Cost and Utilization Project (HCUP) database (2007-2016) was used. We identified all patients ≥ 50 years who underwent elective primary TKA using ICD-9-CM code 81.54 for UTKA and BTKA from January 1, 2012 to September 30, 2015, and ICD-10-CM codes 0SRC0x and 0SRD0x thereafter. Patients with inflammatory arthritis, pathologic fractures, metastatic disease and avascular necrosis were excluded. Major in-hospital complications included post-operative myocardial infarction, prosthetic device complication, surgical wound infection, and venous thromboembolism. Differences in temporal trends in utilization and major in-hospital complications of BTKA vs UTKA were compared between AAs and Whites. Multivariable logistic regression models were used to assess differences in both these trends between AAs and Whites after adjusting for individual (age, sex, Elixhauser comorbidity index, and morbid obesity), hospital level (hospital volume, bed size, region and teaching status) and community level (median household income) variables. Discharge weights were used to enable nationwide estimates. Multiple imputation was performed for missing race variable (11.9%).Results:From 2007 to 2016, an estimated 276,194 BTKA (unweighted observations 56,675) and 5,528,429 UTKA (unweighted observations 1,131,329) were identified (Table 1). Females had a higher proportion of TKAs performed (62.1% UTKA vs 55.9% BTKA). Patients had fewer comorbidities (measured by the Elixhauser Index) when undergoing BTKA compared to UTKA. The proportion of BTKA amongst all TKAs declined from 5.53% in 2007-08 to 4.03% in 2015-16. AAs continued to have significantly lower proportion of BTKA utilization compared to Whites (4.68% in AAs vs 6.08% in Whites in 2007-08, whereas 3.28% in AAs vs 4.19% in Whites in 2015-16, adjusted p < 0.001) (Figure 1a). In-hospital complication rates for UTKA and BTKA were significantly higher in Whites compared to AAs throughout the study period (0.77% in AAs vs 0.9% in Whites in 2007-08, whereas 0.69% in AAs vs 0.83% in Whites in 2015-16, adjusted p < 0.001) (Figure 1b). The results were similar after imputation of missing race values.Conclusion:In this nationwide sample of patients from 2007 to 2016, we found that AAs have lower utilization rate of BKTA compared to Whites, however the in-hospital complication rates were significantly higher in Whites.References:N/ATable 1.Weighted frequencies and percentages of demographic characteristics among unilateral TKA vs. bilateral TKA (N = 6, 236, 426).VariableUnilateral TKABilateral TKAPaN = 5,528,429(Unweighted N = 1,131,329)N = 276,194(Unweighted N = 56,675)Patient CharacteristicsAge, mean (SD)67.4 (0.02)65.0 (0.06)<.0001Sex: Female, n(%)3,429,484 (62.1)154,442 (55.9)<.0001Race, n(%): White4,051,648 (50.9)212,468 (76.9)<.0001 African American352,933 (6.4)14,441 (5.2) Other464,407 (8.4)16,443 (6.0) Missing659,439 (11.9)32,842 (11.9)Morbid Obesity, n(%)401,892 (7.3)20,411 (7.4)0.47Elixhauser Indexd, n(%):<.0001 0716,559 (13.0)41,550 (15.0) 1-44,484,941 (81.1)220,638 (80.0) ≥ 5326,928 (5.9)14,007 (5.1)Disclosure of Interests:Bella Mehta: None declared, Kaylee Ho: None declared, Jennifer Bido: None declared, Michael Parks Consultant of: Zimmer Biomet, Linda Russell: None declared, Susan Goodman Shareholder of: Reginosine- Investment, Grant/research support from: Novartis, Horizon, Consultant of: Novartis, Celgene, UCB, Said Ibrahim: None declared

Abstract
PURPOSE The prevalence of childhood obesity continues to increase worldwide. The aims of this study were to (1) assess the psychological well-being and rates of teasing of Spanish children with obesity (OG) and compare them with their non-overweight peers (NG), and (2) analyze the mediating role of weight-related teasing on the relation between children's BMI z score and psychological well-being. METHODS The cross-sectional study included 50 preadolescents with obesity, matched with non-overweight children according to age, sex, and socioeconomic status, who were assessed via self-report instruments measuring anxiety, depression, self-esteem, and teasing. RESULTS The OG reported higher anxiety, depression, and teasing, and lower self-esteem. SEM revealed that children who scored worse on instruments assessing psychological well-being had higher BMI z scores. Weight-related teasing predicted poor psychological well-being scores and weight-related teasing mediated the relation between BMI and psychological well-being. CONCLUSIONS The high rates of anxiety, depression, and weight-related teasing, as well as the low self-esteem, which was observed amongst the children with obesity, raise concerns about the quality of life of this population. Furthermore, the finding that weight-related teasing mediated the relationship between BMI and psychological well-being adds to a growing body of research, highlighting the harmful effects of weight-related stigma. Overall, these results highlight the importance of early intervention to assess for, and address, the presence of weight-related teasing and psychological well-being difficulties in preadolescents with obesity. LEVEL OF EVIDENCE Level III, case-control study.

Abstract
Background Black and Hispanic patients with osteoarthritis have more pain and worse function than Whites at the time of arthroplasty. Whether this is true for patients with rheumatoid arthritis (RA) is unknown. Methods This cross-sectional study used data on RA patients acquired between October 2013 and November 2018 prior to elective total knee (TKA) or hip arthroplasty (THA). Pain, function, and disease activity were assessed using the visual analogue scale (VAS), the Multidimensional Health Assessment Questionnaire (MDHAQ), and the Disease Activity Score (DAS28-ESR). We linked the cases to census tracts using geocoding to determine the community poverty level. Race, education, income, insurance and medications were collected via self-report. Using multivariable linear and logistic models we examined whether minority status predicted pain, function and RA disease activity at the time of arthroplasty. Results Thirty seven (23%) of the 164 patients were Black or Hispanic (minorities). The MDHAQ and DAS28-ESR were not significantly worse while VAS pain score was significantly worse in minority patients (p = 0.03). There was no significant difference in education between the groups. Insurance varied significantly; 29% of minority patients had Medicaid vs. 0% of Whites (p < 0.0001). In the multivariable analyses minority status was not significantly associated with DAS28-ESR [p = 0.66], MDHAQ [p = 0.26], or VAS pain [p = 0.18]. Conclusions For Black and/or Hispanic patients with RA undergoing THA or TKA at a high-volume specialty hospital, unlike Black or Hispanic patients with osteoarthritis (OA), there was no association with worse pain, function, or RA disease activity at the time of elective arthroplasty.

Abstract
Recent human genetic studies suggest that cells of the innate immune system have a primary role in the pathogenesis of neurodegenerative diseases. However, the results from these studies often do not elucidate how the genetic variants affect the biology of these cells to modulate disease risk. Here, we applied a tensor decomposition method to uncover disease associated gene networks linked to distal genetic variation in stimulated human monocyte and macrophage gene expression profiles. We report robust evidence that some disease associated genetic variants affect the expression of multiple genes in trans. These include a Parkinson's disease locus influencing the expression of genes mediated by a protease that controls lysosomal function, and Alzheimer's disease loci influencing the expression of genes involved in type 1 interferon signaling, myeloid phagocytosis, and complement cascade pathways. Overall, we uncover gene networks in induced innate immune cells linked to disease associated genetic variants, which may help elucidate the underlying biology of disease.

Abstract
BACKGROUND Previous research has suggested that patients with peripheral artery disease (PAD) are not offered adequate risk factor modification, despite their high cardiovascular risk. The aim of this study was to assess the cardiovascular profiles of patients with PAD and quantify the survival benefits of target-based risk factor modification. METHODS The Vascular and Endovascular Research Network (VERN) prospectively collected cardiovascular profiles of patients with PAD from ten UK vascular centres (April to June 2018) to assess practice against UK and European goal-directed best medical therapy guidelines. Risk and benefits of risk factor control were estimated using the SMART-REACH model, a validated cardiovascular prediction tool for patients with PAD. RESULTS Some 440 patients (mean(s.d.) age 70(11) years, 24·8 per cent women) were included in the study. Mean(s.d.) cholesterol (4·3(1·2) mmol/l) and LDL-cholesterol (2·7(1·1) mmol/l) levels were above recommended targets; 319 patients (72·5 per cent) were hypertensive and 343 (78·0 per cent) were active smokers. Only 11·1 per cent of patients were prescribed high-dose statin therapy and 39·1 per cent an antithrombotic agent. The median calculated risk of a major cardiovascular event over 10 years was 53 (i.q.r. 44-62) per cent. Controlling all modifiable cardiovascular risk factors based on UK and European guidance targets (LDL-cholesterol less than 2 mmol/l, systolic BP under 140 mmHg, smoking cessation, antiplatelet therapy) would lead to an absolute risk reduction of the median 10-year cardiovascular risk by 29 (20-38) per cent with 6·3 (4·0-9·3) cardiovascular disease-free years gained. CONCLUSION The medical management of patients with PAD in this secondary care cohort was suboptimal. Controlling modifiable risk factors to guideline-based targets would confer significant patient benefit.

Abstract
Recently, the study of ancient DNA (aDNA) has been greatly enhanced by the development of second-generation DNA sequencing technologies and targeted enrichment strategies. These developments have allowed the recovery of several complete ancient genomes, a result that would have been considered virtually impossible only a decade ago. Prior to these developments, aDNA research was largely focused on the recovery of short DNA sequences and their use in the study of phylogenetic relationships, molecular rates, species identification and population structure. However, it is now possible to sequence a large number of modern and ancient complete genomes from a single species and thereby study the genomic patterns of evolutionary change over time. Such a study would herald the beginnings of ancient population genomics and its use in the study of evolution. Species that are amenable to such large-scale studies warrant increased research effort. We report here progress on a population genomic study of the Adélie penguin (Pygoscelis adeliae). This species is ideally suited to ancient population genomic research because both modern and ancient samples are abundant in the permafrost conditions of Antarctica. This species will enable us to directly address many of the fundamental questions in ecology and evolution.

Abstract
Abstract
Triple negative breast cancer (TNBC) represents a particularly aggressive and difficult to treat form of breast cancer. No specific genetic alterations have been described as characteristic of the disease, with the exception of association with BRCA1/2, EGFR, and KRAS mutations. In this study, we sought to define clinically actionable mutations in untreated metastatic tumors as well as compare the mutational status of metastatic samples with germ-line and primary tumors using whole exome sequencing.
We prospectively enrolled 38 patients with newly diagnosed metastatic TNBC and collected matched specimens of germ-line DNA, primary tumor and metastatic tumor. Median DFI from time of initial primary diagnosis to recurrence was 18 months (IQR = 1-24 months) and 9 patients presented with de novo metastatic disease. 34/38 patients went on to receive first-line treatment with nab-paclitaxel, carboplatin, and bevacizumab and ORR/PFS/OS are available.
Sites of TNBC metastatic tissue (n = 31) included: liver (10), chest wall (13), non-regional lymph nodes (4), and lung (4). 7 patients had inadequate metastatic tumor for sequencing. We performed whole-exome sequencing for all samples using the Agilent solution-based system of exon capture, which uses RNA baits to target all protein coding genes (CCDS database), as well as ∼700 human miRNAs from miRBase (v13). In all, we generated over 10 GB of sequencing data using high throughput sequencing on the Illumina platform.
We observed striking genetic heterogeneity among the metastatic and primary tumors. There was no single driver mutation that was common to the metastatic tumors indicating the diverse genetic pathways that contribute to metastasis. Early analysis suggests that mutations in APC and MTOR occur more frequently in metastatic tumors than in primary tumors. Nonsense mutations of ER were detected in both primary and metastatic tumors but not in germ-line DNA. EGFR and HER2 mutations were not found in any of the primary or metastatic TNBC samples.

Abstract
Critical to conservation efforts and other investigations at low taxonomic levels, DNA sequence data offer important insights into the distinctiveness, biogeographic partitioning and evolutionary histories of species. The resolving power of DNA sequences is often limited by insufficient variability at the intraspecific level. This is particularly true of studies involving plant organelles, as the conservative mutation rate of chloroplasts and mitochondria makes it difficult to detect polymorphisms necessary to track genealogical relationships among individuals, populations and closely related taxa, through space and time. Massively parallel sequencing (MPS) makes it possible to acquire entire organelle genome sequences to identify cryptic variation that would be difficult to detect otherwise. We are using MPS to evaluate intraspecific chloroplast-level divergence across biogeographic boundaries in narrowly endemic and widespread species of Pinus. We focus on one of the world's rarest pines - Torrey pine (Pinus torreyana) - due to its conservation interest and because it provides a marked contrast to more widespread pine species. Detailed analysis of nearly 90% ( approximately 105 000 bp each) of these chloroplast genomes shows that mainland and island populations of Torrey pine differ at five sites in their plastome, with the differences fixed between populations. This is an exceptionally low level of divergence (1 polymorphism/ approximately 21 kb), yet it is comparable to intraspecific divergence present in widespread pine species and species complexes. Population-level organelle genome sequencing offers new vistas into the timing and magnitude of divergence within species, and is certain to provide greater insight into pollen dispersal, migration patterns and evolutionary dynamics in plants.

Abstract
This prospective study evaluated differences in vastus medialis (VM) and gluteus medius (GM) EMG amplitude:composite hip abductor (gluteus maximus, gluteus medius, tensor fascia lata) EMG amplitude ratios among subjects with low or high relative femoral anteversion. Data were collected during the performance of a non-weight bearing, non-sagittal plane maximal volitional effort isometric combined hip abduction-external rotation maneuver. Eighteen nonimpaired athletically active females participated in this surface EMG study. Medial hip rotation (relative femoral anteversion estimate) was measured with a handheld goniometer. Subjects were grouped by medial hip rotation displacement (group 1 < or = 42 degrees =36.1+/-7 degrees and group 2 > 42 degrees =52.7+/-7 degrees ) for statistical analysis (Mann Whitney U-tests, p < 0.05). Group 2 had decreased VM (42+/-23% vs. 69+/-30%, U=19, p=0.034) and GM (62+/-25% vs. 96+/-39%, U=19, p=0.034) normalized mean peak EMG amplitude:composite mean peak hip abductor EMG amplitude ratios compared to group 1. Decreased normalized VM (-27%) and GM (-34%) EMG amplitudes among subjects with increased relative femoral anteversion suggest reduced dynamic frontal and transverse plane femoral control from these muscles, possibly contributing to the increased incidence of non-contact knee injury observed among athletic females.

Abstract
PURPOSE To evaluate the magnitude of the solubility advantage for amorphous pharmaceutical materials when compared to their crystalline counterparts. METHODS The thermal properties of several drugs in their amorphous and crystalline states were determined using differential scanning calorimetry. From these properties the solubility advantage for the amorphous form was predicted as a function of temperature using a simple thermodynamic analysis. These predictions were compared to the results of experimental measurements of the aqueous solubilities of the amorphous and crystalline forms of the drugs at several temperatures. RESULTS By treating each amorphous drug as either an equilibrium supercooled liquid or a pseudo-equilibrium glass, the solubility advantage compared to the most stable crystalline form was predicted to be between 10 and 1,600 fold. The measured solubility advantage was usually considerably less than this, and for one compound studied in detail its temperature dependence was also less than predicted. It was calculated that even for partially amorphous materials the apparent solubility enhancement (theoretical or measured) is likely to influence in-vitro and in-vivo dissolution behavior. CONCLUSIONS Amorphous pharmaceuticals are markedly more soluble than their crystalline counterparts, however, their experimental solubility advantage is typically less than that predicted from simple thermodynamic considerations. This appears to be the result of difficulties in determining the solubility of amorphous materials under true equilibrium conditions. Simple thermodynamic predictions can provide a useful indication of the theoretical maximum solubility advantage for amorphous pharmaceuticals, which directly reflects the driving force for their initial dissolution.

Abstract
PURPOSE Open-angle glaucoma may develop after surgery for congenital or developmental cataract with an incidence ranging from 3% to 41%. The pathogenesis of "aphakic" (open-angle) glaucoma remains unknown. Despite numerous reported clinical series (>1000 eyes), we are unaware of any reported case of open-angle glaucoma after primary intraocular lens (IOL) implantation for congenital or developmental cataract. We decided to test the hypothesis that primary posterior chamber IOL implantation might decrease the incidence of open-angle glaucoma in children. METHODS Pseudophakic eyes were collected from surgeons who contributed data to a refractive study and who monitored intraocular pressure on a regular basis. IOL implantation was commonly performed in eyes with a corneal diameter >10 mm. Comparable primary data on aphakic eyes were included from 2 published studies on aphakic glaucoma, which included corneal diameters and the patient's age at surgery. Glaucoma-free survival estimates for each cohort were estimated. RESULTS Only 1 case of glaucoma was found among 377 eyes with primary pseudophakia (mean age of patient, 5.1 +/- 4.7 years; mean follow-up, 3.9 +/- 2.7 years). There were 14 eyes (11.3%) with glaucoma among 124 aphakic eyes (mean age of patient, 2.7 +/- 2.6 years; mean follow-up time, 7.2 +/- 3.9 years). CONCLUSIONS We report a decreased incidence of open-angle glaucoma among eyes rendered primarily pseudophakic compared with those that remained aphakic after cataract surgery. We propose 2 theories on the possible mechanism of reduction in the incidence of glaucoma in pseudophakic eyes.

Abstract
The minimum duration signal necessary to identify a set of spoken words was established by the gating technique; most words could be identified before their acoustic offset. Gated words were used as congruous and incongruous sentence completions, and isolation points established in the gating experiment were compared with the time course of semantic integration evident in event-related brain potentials. Differential N400 responses to contextually appropriate and inappropriate words were observed about 200 ms before the isolation point. Semantic processing was evident before the acoustic signal was sufficient to identify the words uniquely. Results indicate that semantic integration can begin to operate with only partial, incomplete information about word identity. Influences of semantic constraint, word frequency, and rate of presentation are described.

Abstract
The objective of this study was to examine vaccine type-specific antibody titers eight months after a five-valent pneumococcal conjugate vaccine (PCV) in human immunodeficiency virus (HIV) and non-HIV-infected children under two years of age. Sixteen HIV-infected and 14 non-HIV-infected children under two years of age, and of similar age, race and sex distribution, received three doses (separated by two months each) of a five-valent oligosaccharide PCV (types 6B, 14, 18C, 19F, and 23F separately coupled to diphtheria CRM197). An additional 11 non-HIV-infected children, of similar demographic distribution to the PCV groups, received three doses of saline placebo. sera were collected just prior to, and at one and eight months after the three study drug doses. Serum vaccine type-specific pneumococcal IgG antibodies were measured by enzyme-linked immunoabsorbant assay (ELISA). There was an impressive rise in antibody titers pre- to one month post-third PCV in both the HIV (58-970-fold) and non-HIV-infected (19-553-fold) children. There was a rapid and similar drop in antibody titers eight months after the PCV series for both HIV (range 69-87% drop) and non-HIV-infected (range 57-79% drop) subjects respectively. However, 46% of the antibody titers from HIV-infected children and 62% of the titers from non-HIV-infected children were still > 1.0 microgram ml-1 compared to placebo recipients for whom only 5% of the titers were > 1.0 microgram ml-1 (p < 0.05). At the eight month post-PCV series blood draw, there were no significant differences in the GMTs, the percent drop in titers, or proportion of titers > 1.0 microgram ml-1 between the five HIV-infected children who had advanced (CDC class: N3, A3, B2-3, C1-3) compared to the 11 children with mild (CDC class: N1-2, A1-2, B1) HIV disease at the time of their first PCV dose. Eight months after the PCV series, the proportion of titers (combined all five serotypes) > 1.0 microgram ml-1 was slightly, but significantly, lower for HIV-infected subjects (46%) compared to non-HIV-infected subjects (62%) (p < 0.05). These data are helpful in describing the kinetics of antibody responses to pneumococcal conjugate vaccines in both HIV and non-HIV-infected young children.

Abstract
OBJECTIVE To assess the safety and immunogenicity of three doses of a five-valent (types 6B, 23F, 14, 18C, and 19F) pneumococcal conjugate vaccine (PCV) among children younger than 2 years who are and are not infected with human immunodeficiency virus (HIV). METHODS A convenience sample of 18 HIV-infected children 2 years and younger (mean, 12.9 months) received three doses (each separated by 2 months) of PCV. An additional convenience sample of 33 non-HIV-infected children of virtually identical age, race, and sex as the HIV-infected group were randomized in a double-blind fashion to receive three doses of PCV or saline placebo. Safety data were collected for 72 hours after each vaccination. Sera were obtained before each and 1 month after the third vaccination to determine vaccine type-specific immunoglobulin G pneumococcal antibody titers by an enzyme-linked immunosorbent assay. RESULTS Seventeen HIV- and 30 non-HIV-infected children completed the study. The PCV was well tolerated by both HIV- and non-HIV-infected children. No significant differences in local or systemic reactions were noted between HIV- and non-HIV-infected PCV or placebo recipients. Three doses of PCV were immunogenic, as evidenced by 16- to 659-fold increases in type-specific geometric mean antibody titers over prevaccination levels in HIV- and non-HIV-infected children. With respect to an arbitrary protective level, 78% of the antibody titers from HIV-infected children and 88% of the titers from non-HIV-infected children were 1.0 microgram/mL or greater 1 month after the third PCV dose. HIV-infected children with milder disease (Centers for Disease Control and Prevention classes N1-2, A1-2, and B1) were more likely to have protective antibody titers after the first and second PCV doses than HIV-infected children with more advanced disease (Centers for Disease Control and Prevention classes N3, A3, B2-3, and C1-3). However, after the third PCV dose, these differences disappeared. CONCLUSION Three doses of PCV seem safe and immunogenic in both HIV- and non-HIV-infected children younger than 2 years. This type of vaccine should result in a marked reduction in systemic pneumococcal disease in both HIV- and non-HIV-infected children. Given the high incidence of invasive pneumococcal disease in HIV-infected children, this vaccine may markedly improve the quality of life for this unfortunate group of children.

Abstract
OBJECTIVES The purpose of this Asymptomatic Cardiac Ischemia Pilot (ACIP) data bank study was to characterize angiographic features of coronary pathology of patients enrolled in the ACIP study. BACKGROUND Ischemia during ambulatory electrocardiographic (AECG) monitoring is associated with increased morbidity and mortality. Reports relating AECG ischemia to severity or complexity of coronary artery disease are few in number and small in size and have produced conflicting results. METHODS Coronary angiograms from patients with asymptomatic AECG ischemia enrolled in the ACIP study were reviewed at a central core laboratory. Quantitative measurement of percent stenosis and Thrombolysis in Myocardial Infarction flow grades were used to assess the severity of coronary artery disease. Lesions were also evaluated for the presence of intracoronary thrombus, ulceration and lumen contour as indicators of stenosis complexity. In addition, comparisons were made with 27 patients screened for the ACIP study, but who were found ineligible because they did not have AECG ischemia on 48-h Holter monitoring. RESULTS A total of 329 (75%) of 439 patients with AECG ischemia had multivessel coronary artery disease. Proximal stenoses > or = 50% diameter reduction were common in patients with AECG ischemia (62.2%), as were proximal stenoses > or = 70% (38.7%). Features suggesting complex plaque were found in 50.1% of patients with AECG ischemia. CONCLUSIONS Multivessel coronary artery disease, severe proximal stenoses and features of complex plaque were observed frequently in patients who exhibited AECG ischemia. The presence of severe and complex coronary artery disease may explain, in part, the increased risk for adverse outcome associated with ischemia during activities of daily life.

Abstract
OBJECTIVE To compare the safety and immunogenicity of a 5-valent pneumococcal conjugate vaccine to a licensed 23-valent polysaccharide pneumococcal vaccine in HIV-infected and non-HIV-infected children > or = 2 years old. METHODS Thirty HIV-infected and 30 non-HIV-infected children > or = 2 years old were randomized to receive either a 5-valent pneumococcal conjugate vaccine (PCV) or a 23-valent pneumococcal polysaccharide vaccine (PPV) intramuscularly. Children who received PCV initially were given PPV after 6 weeks. Sera were obtained before and at 6 and 12 weeks after the first vaccination to determine IgG pneumococcal antibody titers by enzyme-linked immunosorbent assay to the 5 serotypes represented in the PCV. RESULTS Both vaccines were well-tolerated with no significant differences in the rates of fever (0 to 14%) or local reactions (0 to 40%) noted between PCV and PPV recipients. Pre-first vaccination geometric mean antibody titers (combined PCV and PPV recipients) to 3 of the 5 pneumococcal types tested were significantly lower in HIV-infected than in non-HIV-infected children (in microgram/ml: type 6B, 0.179 vs. 0.565; type 14, 0.026 vs. 0.060; type 23F, 0.025 vs. 0.119, respectively; P < 0.05). Fewer > or = 4-fold titer rises were observed in HIV vs. non-HIV-infected children whether they received PCV initially (60% vs. 79%, P < 0.05) or PPV (31% vs. 59%, P < 0.05). Also PCV elicited more > or = 4-fold titer rises compared with PPV in HIV-infected (60% vs. 31%, P < 0.05) and non-HIV-infected (79% vs. 59%, P < 0.05) children. No consistent antibody-boosting effect was noted in subjects who received PPV after PCV. CONCLUSIONS We conclude that antibody responses to natural infection, PCV and particularly PPV are poorer in HIV-infected than in non-HIV-infected children. PCV is as safe as and more immunogenic than the currently licensed PPV among HIV-infected and non-HIV-infected children.

Abstract
We report on a mother and daughter with nonsyndromal cryptophthalmos. Both patients have additional ocular anomalies, including microphthalmia, retinal dysplasia, and Peters anomaly. The periocular and lid changes seen in these individuals are distinct from those seen in typical cryptophthalmos. The apparent dominant mode of inheritance in this family distinguishes this condition from autosomal recessive isolated cryptophthalmos and from the Fraser or cryptophthalmos syndrome.

Abstract
A major issue concerning central auditory nervous system (CANS) evaluation is the appropriateness of the norms used. The use of currently available CANS norms in the evaluation of urban black children may result in inaccurate diagnosis. The subjects of this study were 40 black children who were intellectually, functionally, and behaviorally normal. Ages ranged from 7 years 4 months to 11 years 4 months. Candidates were identified by classroom teachers, then evaluated by specialists, using interviews, records, observation, and tests to identify "hidden" handicaps. Performance data were obtained on each of the age groups for the following CANS tests: time compressed speech; competing sentences; filtered speech; binaural fusion; alternating sentences; and staggered spondaic words. The results indicated that the performance of normal black children on the CANS test used in this study is not quantitatively nor qualitatively different from the performance of normal white subjects on the same tests.

Abstract
Customary procedures used to determine chromosomal inheritance do not disclose many of the chromosomal polymorphisms known to be present, resulting in uninformative families. The sequential printing of individual chromosomes presented here is a technique that has increased the number of informative families in our studies. This technique has revealed previously unseen heritable chromosome differences and allowed the designation of parental origin.
