Abstract
Samples from 450 homes with shallow private wells throughout the state of Wisconsin (USA) were collected and analyzed for 44 individual per- and polyfluoroalkyl substances (PFAS), general water quality parameters, and indicators of human waste as well as agricultural influence. At least one PFAS was detected in 71% of the study samples, and 22 of the 44 PFAS analytes were detected in one or more samples. Levels of PFOA and/or PFOS exceeded the proposed Maximum Contaminant Levels of 4 ng/L, put forward by the U.S. Environmental Protection Agency (EPA) in March 2023, in 17 of the 450 samples, with two additional samples containing PFHxS ≳ 9 ng/L (the EPA-proposed hazard index reference value). Those samples above the referenced PFAS levels tend to be associated with developed land and human waste indicators (artificial sweeteners and pharmaceuticals), which can be released to groundwater via septic systems. For a few samples with levels of PFOA, PFOS, and/or PFHxS > 40 ng/L, application of wastes to agricultural land is a possible source. Overall, the study suggests that human waste sources, septic systems in particular, are important sources of perfluoroalkyl acids, especially ones with ≤8 perfluorinated carbons, in shallow groundwater.

Abstract
BACKGROUND The Association of American Medical Colleges instituted a standardized video interview (SVI) for all applicants to emergency medicine (EM). It is unclear how the SVI affects a faculty reviewer's decision on likelihood to invite an applicant (LTI) for an interview. OBJECTIVES The objective was to determine whether the SVI affects the LTI. METHODS Nine Accreditation Council of Graduate Medication Education (ACGME)-accredited EM residency programs participated in this prospective, observational study. LTI was defined on a 5-point Likert scale as follows: 1 = definitely not invite, 2 = likely not invite, 3 = might invite, 4 = probably invite, 5 = definitely invite. LTI was recorded at three instances during each review: 1) after typical screening (blinded to the SVI), 2) after unblinding to the SVI score, and 3) after viewing the SVI video. RESULTS Seventeen reviewers at nine ACGME-accredited residency programs participated. We reviewed 2,219 applications representing 1,424 unique applicants. After unblinding the SVI score, LTI did not change in 2,065 (93.1%), increased in 85 (3.8%) and decreased in 69 (3.1%; p = 0.22). In subgroup analyses, the effect of the SVI on LTI was unchanged by United States Medical Licensing Examination score. However, when examining subgroups of SVI scores, the percentage of applicants in whom the SVI score changed the LTI was significantly different in those that scored in the lower and upper subgroups (p < 0.0001). The SVI video was viewed in 816 (36.8%) applications. Watching the video did not change the LTI in 631 (77.3%); LTI increased in 106 (13.0%) and decreased in 79 (9.7%) applications (p = 0.04). CONCLUSIONS The SVI score changed the LTI in 7% of applications. In this group, the score was equally likely to increase or decrease the LTI. Lower SVI scores were more likely to decrease the LTI than higher scores were to increase the LTI. Watching the SVI video was more likely to increase the LTI than to decrease it.

Abstract
Introduction In 2017, the Standardized Video Interview (SVI) was required for applicants to emergency medicine (EM). The SVI contains six questions highlighting professionalism and interpersonal communication skills. The responses were scored (6–30). As it is a new metric, no information is available on correlation between SVI scores and other application data. This study was to determine if a correlation exists between applicants’ United States Medical Licensing Examination (USMLE) and SVI scores. We hypothesized that numeric USMLE Step 1 and Step 2 Clinical Knowledge (CK) scores would not correlate with the SVI score, but that performance on the Step 2 Clinical Skills (CS) portion may correlate with the SVI since both test communication skills. Methods Nine EM residency sites participated in the study with data exported from an Electronic Residency Application Service (ERAS®) report. All applicants with both SVI and USMLE scores were included. We studied the correlation between SVI scores and USMLE scores. Predetermined subgroup analysis was performed based on applicants’ USMLE Step 1 and Step 2 CK scores as follows: (≥ 200, 201–220, 221–240, 241–260, >260). We used linear regression, the Kruskal-Wallis test and Mann-Whitney U test for statistical analyses. Results 1,325 applicants had both Step 1 and SVI scores available, with no correlation between the overall scores (p=0.58) and no correlation between the scores across all Step 1 score ranges, (p=0.29). Both Step 2 CK and SVI scores were available for 1,275 applicants, with no correlation between the overall scores (p=0.56) and no correlation across all ranges, (p=0.10). The USMLE Step 2 CS and SVI scores were available for 1,000 applicants. Four applicants failed the CS test without any correlation to the SVI score (p=0.08). Conclusion We found no correlation between the scores on any portion of the USMLE and the SVI; therefore, the SVI provides new information to application screeners.

Abstract
Infiltration of treated wastewater (TWW) to recharge depleted aquifers, often referred to as managed aquifer recharge, is a solution to replenish groundwater resources in regions facing water scarcity. We present a mass balance approach to infer the amounts of five pharmaceuticals (carbamazepine, diclofenac, fenoprofen, gemfibrozil, and naproxen) degraded in column experiments based on concentrations of pharmaceuticals in the aqueous and solid (sorbed) phases. Column experiments were conducted under three different conditions: continuous infiltration, wetting and drying cycles, and wetting and drying cycles with elevated concentrations of antibiotics (which may reduce microbially aided degradation of other compounds). A mass balance comparing pharmaceutical mass in the water phase over the 16-month duration of the experiments to mass sorbed to the soil was used to infer the mass of pharmaceuticals degraded. Results show sorption as the main attenuation mechanism for carbamazepine. About half of the mass of diclofenac was degraded with wetting and drying cycles, but no significant degradation was found for continuous infiltration, while 32% of infiltrated mass sorbed. Fenoprofen was degraded in the shallow and aerobic part of the soil, but degradation appeared to cease beyond 27 cm depth. Gemfibrozil attenuated through a combination of degradation and sorption, with slight increases in attenuation with depth from both mechanisms. Naproxen degraded progressively with depth, resulting in attenuation of >90% of the mass. In the column with elevated concentrations of antibiotics, the antibiotics attenuated to about 50% or less of inflow concentrations by 27 cm depth and within this zone, less degradation of the other compounds was observed.

Abstract
OBJECTIVES To determine whether the addition of metronomic chemotherapy improved outcome for dogs with splenic haemangiosarcoma treated with splenectomy and adjuvant maximum tolerated dose chemotherapy. MATERIALS AND METHODS Medical records were examined retrospectively for dogs with splenic haemangiosarcoma that had undergone splenectomy followed by anthracycline-based chemotherapy. Thirty-nine dogs underwent splenectomy followed by maximum tolerated dose chemotherapy with an anthracycline, cyclophosphamide, or both (Group 1). Twenty-two dogs underwent splenectomy followed by adjuvant maximum tolerated dose chemotherapy with an anthracycline, cyclophosphamide, or both, plus metronomic chemotherapy (Group 2). Dogs in both groups were further separated into those treated with either maximum tolerated dose anthracycline or maximum tolerated dose anthracycline and cyclophosphamide. RESULTS Median progression-free survival was 165 days and median overall survival time was 180 days in Group 1. Median progression-free survival was 185 days and median overall survival time was 212 days in Group 2. In both groups, the overall survival was shorter in dogs that had received maximum tolerated dose cyclophosphamide. CLINICAL SIGNIFICANCE The addition of metronomic to maximum tolerated dose chemotherapy protocols does not appear to improve outcome in dogs with splenic haemangiosarcoma treated with splenectomy and maximum tolerated dose chemotherapy.

Abstract
OBJECTIVES: To validate a novel method for measuring the clinically relevant bracket slot and use these methods to test the hypothesis that various metal injection molded (MIM) and esthetic ceramic injection molded (CIM) brackets have a bracket slot accuracy within 1 mil (0.001") of their reported slot dimension. MATERIALS AND METHODS: A Nikon iNEXIV-VMA-2520 laser microscope was used to measure slots of six series of CIM brackets and two series of MIM brackets via a vision measuring system of 256 gray levels to capture each edge of the slot, largely taking out human subjectivity. This system had a maximum permissible error of 2 + 8 L/1000 μm with a point resolution of 0.1 μm and was estimated to be more accurate than previous methods by a factor of 10. The video image for each bracket was autofocused by a blinded operator, and 40 point-to-line measurements were calculated along the clinical slot and averaged. RESULTS: Vertical slot dimension varied from series to series and within the series of brackets. Three of six CIM and two of three MIM brackets had a statistically significant mean slot size 0.001 inches larger than reported. The reported precision of these CIM brackets, as determined from standard deviation, varied from series to series. CONCLUSIONS: A novel system that incorporates parallelism into analysis of vertical bracket slot dimension was described. When the entire clinically relevant slot was considered, MIM and CIM brackets had similar precision but were significantly oversized, with contribution from a nonparallel, likely diverging, vertical slot dimension.

Abstract
BACKGROUND In humans geographical differences in the incidence and presentation of various cancers have been reported. However, much of this information has not been collected in veterinary oncology. AIM The purpose of this study was to determine if a geographic difference in progression free survival exists for dogs with lymphoma treated within the US. MATERIALS AND METHODS Medical records of 775 cases of canine lymphoma from 3 US regions (west, south and north), treated with CHOP chemotherapy, were retrospectively evaluated. Cases were collected from referral institutions and were required to have received at least one doxorubicin treatment and have follow up information regarding time to progression. RESULTS Significant differences in sex (p = 0.05), weight (p = 0.049), stage (p < 0.001), immunophenotype (p = <0.001), and number of doxorubicin doses (p = 0.001) were seen between regions. Upon univariate analysis, progression free survival (PFS) differed by region (p = 0.006), stage (p = 0.009), sub-stage (p = 0.0005), and immunophenotype (p = 0.001). A multivariable Cox regression model showed that dogs in the western region had a significantly shorter PFS when compared to the south and east. CONCLUSION PFS was significantly affected by stage, sub-stage and phenotype.

Abstract
Abstract
Breast density is associated with reduced imaging sensitivity and specificity for breast cancer (BC). Women with dense breasts are at a four- to six-fold increased risk of developing BC. A biochemical approach that is not affected by density would provide an additional tool to health-care professionals who are managing women with dense breasts and suspicious imaging findings. Videssa® Breast, a combinatorial proteomic biomarker assay, comprised of Serum Protein Biomarkers (SPBs) and Tumor –Associated Autoantibodies (TAAbs) integrated with clinical characteristic data to produce one diagnostic score that reliably detects BC was recently developed as an adjunctive tool to imaging. The goal of this study was to determine whether the diagnostic performance of Videssa® Breast was impacted by breast density.
Provista-001 enrolled 351 participants under the age of 50 years with no prior history of breast biopsy, and Provista-002 cohort one enrolled 210 participants under the age of 50 years with no history of breast biopsy within six months; all participants were assessed as BI-RADS 3 or 4. Breast density status was retrospectively obtained for participants; the four American College of Radiology breast density categories (a, b, c, and d) used for clinical reporting were applied. Serum was collected and tested with Videssa® Breast. Women were categorized into Dense, which included categories c and d, and Non-dense, which included categories a and b, groups.
To understand the performance of Videssa® Breast in women with dense breasts, the clinical sensitivity, specificity, NPV and PPV were evaluated in the dense and non-dense groups from the comprehensive Provista-001 and Provista-002 set (n=545). Of these 545, breast density information was available for 454; 62.6% (n=284) were categorized as having dense breasts and 37.4% (n=170) were categorized as having non-dense breasts. The sensitivity of Videssa® Breast in the non-dense and dense groups was 92.3% and 88.9%, respectively, and the specificity in the non-dense and dense groups was 86.6% and 81.2%, respectively. No significant differences were observed in the sensitivity (p=1.0) or specificity (p=0.1783) of Videssa® Breast in detecting BC in participants with non-dense breasts compared to those with dense breasts. The NPV in both groups exceeded 99%; the PPV was similar across groups.
In summary, this study demonstrates that Videssa® Breast has comparable performance in women with dense and non-dense breasts. Videssa® Breast demonstrates high sensitivity and specificity for detecting BC (Grades I through III), irrespective of density status. Videssa® breast provides an additional tool for health-care providers when women with dense breasts present with challenging imaging findings. In addition, Videssa® breast provides assurance to a woman with dense breasts that she does not have BC, potentially reducing further anxiety in this higher risk patient population.

Abstract
Introduction Since the creation of Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) patient satisfaction (PS) scores, patient experience (PE) has become a metric that can profoundly affect the fiscal balance of hospital systems, reputation of entire departments and welfare of individual physicians. While government and hospital mandates demonstrate the prominence of PE as a quality measure, no such mandate exists for its education. The objective of this study was to determine the education and evaluation landscape for PE in categorical emergency medicine (EM) residencies. Methods This was a prospective survey analysis of the Council of Emergency Medicine Residency Directors (CORD) membership. Program directors (PDs), assistant PDs and core faculty who are part of the CORD listserv were sent an email link to a brief, anonymous electronic survey. Respondents were asked their position in the residency, the name of their department, and questions regarding the presence and types of PS evaluative data and PE education they provide. Results We obtained 168 responses from 139 individual residencies, representing 72% of all categorical EM residencies. This survey found that only 27% of responding residencies provide PS data to their residents. Of those programs, 61% offer simulation scores, 39% provide third-party attending data on cases with resident participation, 37% provide third-party acquired data specifically about residents and 37% provide internally acquired quantitative data. Only 35% of residencies reported having any organized PE curricula. Of the programs that provide an organized PE curriculum, most offer multiple modalities; 96% provide didactic lectures, 49% small group sessions, 47% simulation sessions and 27% specifically use standardized patient encounters in their simulation sessions. Conclusion The majority of categorical EM residencies do not provide either PS data or any organized PE curriculum. Those that do use a heterogeneous set of data collection modalities and educational techniques. American Osteopathic Association and Accreditation Council for Graduate Medical Education residencies show no significant differences in their resident PS data provision or formal curricula. Further work is needed to improve education given the high stakes of PS scores in the emergency physician’s career.

Abstract
Abstract
The precise diagnosis of breast lesions represents a significant problem in women under the age of 50, especially given the high prevalence of confounding factors such as dense breast. No new approaches have been developed to augment standard of care in the more precise detection of breast cancer. The combination of breast imaging with a robust protein signature that would detect biochemical cues of breast cancer offers a potentially attractive approach to detection regardless of the quality of the radiographic evidence. We have recently tested a protein signature (KARIFY BREAST™) composed of immune-regulatory cytokines, growth factors and tumor-associated autoantibodies (TAAbs). Here, we confirm the hypothesis that this protein signature, combined with standard of care can increase the precision of the diagnosis of breast cancer in women under the age of 50. We have tested this method in a prospective study of 351 women at 8 centers across the US in a randomized and blinded manner. Presented is both data from the initial blood draw and results of the six-month follow up blood draw. The achievement of 93% sensitivity and greater than a 80 percent specificity was demonstrated.
Methods: Provista-001 enrolled 351 patients from 9 sites across the US and will follow patients for 6 months prior to first blood draw under IRB approval. Upon enrollment, patients were randomized to either training or validation groups. Clinical truth was set at equal to or greater than 80% sensitivity/specificity. Serum protein biomarkers and autoantibodies identified in prior proteomic screens were measured prior to biopsy. Individual biomarker (25 serum protein biomarkers (SPB) and TAAbs) concentrations were measured , together with specific patient data were evaluated using various logistic regression models. Additionally, 200 patients were used as a training set to develop and refine new models, which were then validated in the remaining 151 subjects. Clinical findings were compared to biopsy (largely BIRADS 4) or were followed for 6 months and re-assessed (BIRADS 3).
The novel algorithm utilizing patient data, SPBs and TAAb concentrations and regression models were able to distinguish benign from breast cancer lesions in a statistically significant manner. Importantly, the SPBs alone were unable to adequately distinguish benign lesions, consistent with prior work. However, the addition of TAAbs markedly increased both the sensitivity (93%) and specificity (80.3%) of the assay in this group of women. The use of the algorithm in conjunction with imaging detected more lesions than imaging alone.
Our findings suggest that when used in combination, the protein signature developed here and breast imaging provides a more precise detection methodology than either alone. This is particularly important in women under the age of 50 where detection is difficult. The follow-up data at six months (BIRADS 3) have yielded additional data in this understudied group of women. Such as the apparent lack of effect of breast density on early detection when using the algorithm.

Abstract
Vitamin D is well known for its role in promoting skeletal health. Vitamin D status is determined conventionally by circulating 25-dihydroxyvitamin D (25OHD) concentration. There is evidence indicating that circulating 25OHD concentration is affected by variation in Gc, the gene encoding the vitamin D binding protein (DBP). The composite genotype of two single nucleotide polymorphisms (rs7041 and rs4588) results in different DBP isotypes (Gc1f, Gc1s and Gc2). The protein configurational differences among DBP isotypes affect DBP substrate binding affinity. The aims of this study were to determine 1) Gc variant frequencies in a population from an isolated rural region of The Gambia, West Africa (n=3129) with year-round opportunity for cutaneous vitamin D synthesis and 2) the effects of Gc variants on 25OHD concentration (n=237) in a genetically representative sub-group of children (mean (SD) age: 11.9 (4.8) years). The distribution of Gc variants was Gc1f: 0.86, Gc1s: 0.11 and Gc2: 0.03. The mean (SD) concentration of 25OHD was 59.6 (12.9) nmol/L and was significantly higher in those homozygous for Gc1f compared to other Gc variants (60.7 (13.1) vs. 56.6 (12.1) nmol/L, P=0.03). Plasma 25OHD and 1,25(OH)2D concentration was significantly associated with parathyroid hormone in Gc1f-1f but not in the other Gc variants combined. This study demonstrates that different Gc variants are associated with different 25OHD concentrations in a rural Gambian population. Gc1f-1f, thought to have the highest affinity for 25OHD, had the highest 25OHD concentration compared with lower affinity Gc variants. The considerable difference in Gc1f frequency observed in Gambians compared with other non-West African populations and associated differences in plasma 25OHD concentration, may have implications for the way in which vitamin D status should be interpreted across different ancestral groups.

Abstract
Background and Objective.Carbapenem resistance among Enterobacteriaceae is of concern because of increasing prevalence and limited therapeutic options. Limited research has been focused on understanding ertapenem resistance as a more sensitive marker for resistance to other carbapenems. We sought to determine risk factors for acquisition of ertapenem-resistant, meropenem-susceptible, or intermediate Enterobacteriaceae and to assess associated patient outcomes.Design.Retrospective case-control study among adult hospitalized inpatients.Setting.A 902-bed quaternary care urban hospital.Results.Sixty-two cases of ertapenem-resistant Enterobacteriaceae were identified from March 14, 2006, through October 31, 2007, and 62 unmatched control patients were randomly selected from other inpatients with cultures positive for ertapenem-susceptible Enterobacteriaceae. Thirty-seven (60%) of case patient isolates were Enterobacter cloacae, 20 (32%) were Klebsiella pneumoniae, and 5 (8%) were other species of Enterobacteriaceae. Risk factors for ertapenem-resistant Enterobacteriaceae infection included intensive care unit stay (odds ratio [OR], 4.6 [95% confidence interval {CI}, 2.0–10.3]), vancomycin-resistant Enterococcus colonization (OR, 7.1 [95% CI, 2.4–21.4]), prior central venous catheter use (OR, 10.0 [95% CI, 3.0–33.1]), prior receipt of mechanical ventilation (OR, 5.8 [95% CI, 2.1–16.2]), exposure to any antibiotic during the 30 days prior to a positive culture result (OR, 18.5 [95% CI, 4.9–69.9]), use of a β-lactam during the 30 days prior to a positive culture result (OR, 6.9 [95% CI, 3.0–16.0], and use of a carbapenem during the 30 days prior to a positive culture result (OR, 18.2 [95% CI, 2.6–130.0]). For the 62 case patients, 30-day outcomes from the time of positive culture result were 24 discharges (39%), 10 deaths (16%), and 28 continued hospitalizations (44%). The final end point of the hospitalization was discharge for 44 patients (71%) and death for 18 patients (29%).Conclusions.Ertapenem-resistant Enterobacteriaceae are important nosocomial pathogens. Multiple mechanisms of resistance maybe in operation. Additional study of ertapenem resistance is needed.

Abstract
BACKGROUND Previous studies on the effects of health information technology (health IT) on ambulatory quality have had mixed results. New York State has invested heavily in health IT throughout the State, creating a unique opportunity to assess effects on health care quality across multiple communities. OBJECTIVE To determine any association between primary care providers' receipt of funding from New York State's Healthcare Efficiency and Affordability Law for New Yorkers Program (HEAL NY) and ambulatory quality of care. METHODS A statewide, longitudinal cohort study of primary care physicians in New York State was conducted. Data regarding which primary care physicians received funding through the HEAL NY program (Phase 5 or Phase 10) in 2008 or 2009 were obtained from the New York State Department of Health. Health care quality in 2010 was measured using claims data that had been aggregated across 7 commercial health plans across the state. Physicians were divided into 2 groups, based on receipt of HEAL funding (yes/no). Any association was measured between study group and each of 7 quality measures, all of which appear in the Stage 1 federal Meaningful Use program. Negative binomial regression was used, adjusting for provider gender and specialty. RESULTS The study included 3,988 primary care providers, of whom 863 (22%) had received HEAL NY funding. The HEAL-funded physicians provided higher quality of care on 5 of the 7 measures: breast cancer screening, eye exams in patients with diabetes, nephropathy screening in patients with diabetes, influenza vaccination and pneumococcal vaccination (p<0.0001 for all adjusted comparisons). The HEAL-funded group provided higher quality of care by an absolute 2 to 6 percentage points per measure for those 5 measures. CONCLUSION Primary care physicians who received state funding for health IT provided higher quality of care than those who did not receive such funding.

Abstract
The Hedgehog (Hh) pathway is a crucial regulator of muscle development during embryogenesis. We have previously demonstrated that Sonic hedgehog (Shh) regulates postnatal myogenesis in the adult skeletal muscle both directly, by acting on muscle satellite cells, and indirectly, by promoting the production of growth factors from interstitial fibroblasts. Here, we show that in mdx mice, the murine equivalent of Duchenne muscular dystrophy in humans, progression of the dystrophic pathology corresponds to progressive inhibition of the Hh signaling pathway in the skeletal muscle. We also show that the upregulation of the Hh pathway in response to injury and during regeneration is significantly impaired in mdx muscle. Shh treatment increases the proliferative potential of satellite cells isolated from the muscles of mdx mice. This treatment also increases the production of proregenerative factors, such as insulin-like growth factor-1 and vascular endothelial growth factor, from fibroblasts isolated from the muscle of mdx mice. In vivo, overexpression of the Hh pathway using a plasmid encoding the human Shh gene promotes successful regeneration after injury in terms of increased number of proliferating myogenic cells and newly formed myofibers, as well as enhanced vascularization and decreased fibrosis.

Abstract
We describe the case of a 28-year-old-male with no significant medical history who presented with right-sided hemiparesis, bruits over the carotid and subclavian arteries and an elevated erythrocyte sedimentation rate. Imaging studies revealed a middle cerebral artery thrombus and inflammatory changes of the carotid and subclavian arteries and aorta. The diagnosis of Takayasu's arteritis was made and the patient was started on steroids and immunomodulators with good clinical response.
