Abstract
BACKGROUND The no objective testing rule (NOTR) is a decision aid designed to safely identify emergency department (ED) patients with chest pain who do not require objective testing for coronary artery disease. OBJECTIVES The objective was to validate the NOTR in a cohort of U.S. ED patients with acute chest pain and compare its performance to the HEART Pathway. METHODS A secondary analysis of 282 participants enrolled in the HEART Pathway randomized controlled trial was conducted. Each patient was classified as low risk or at risk by the NOTR. Sensitivity for major adverse cardiac events (MACE) at 30 days was calculated in the entire study population. NOTR and HEART Pathways were compared among patients randomized to the HEART Pathway in the parent trial using McNemar's test and the net reclassification improvement (NRI). RESULTS Major adverse cardiac events occurred in 22/282 (7.8%) participants, including no deaths, 16/282 (5.6%) with myocardial infarction (MI), and 6/282 (2.1%) with coronary revascularization without MI. NOTR was 100% (95% confidence interval [CI] = 84.6%-100%) sensitive for MACE and identified 78/282 patients (27.7%, 95% = CI 22.5-33.3%) as low risk. In the HEART Pathway arm (n = 141), both NOTR and HEART Pathway identified all patients with MACE as at risk. Compared to NOTR, the HEART Pathway was able to correctly reclassify 27 patients without MACE as low risk, yielding a NRI of 20.8% (95% CI = 11.3%-30.2%). CONCLUSIONS Within a U.S. cohort of ED patients with chest pain, the NOTR and HEART Pathway were 100% sensitive for MACE at 30 days. However, the HEART Pathway identified more patients suitable for early discharge than the NOTR.

Abstract
Background:
Survival of children born preterm has improved dramatically, but prematurity and low birth weight may increase the risk of renal disease. Children born preterm have a lower glomerular filtration rate (GFR) and higher blood pressure (BP) compared to term peers, but compounding risk factors for renal disease among children born preterm remain poorly characterized. Indeed, patient factors such as obesity may influence the development of kidney disease. Thus, we hypothesize that obesity is associated with decreased renal function in adolescents born preterm with very low birth weight.
Methods:
We measured systolic and diastolic BP, serum creatinine, and urine albumin at age 14 years in 124 adolescents born preterm with very low birth weight (mean birth weight 1056 g). We calculated the GFR by the Schwartz equation and the albumin-to-creatinine ratio (ACR) on morning urine samples. We used generalized linear models to estimate the association between obesity [body mass index (BMI) ≥95
th
%ile for age and sex,
n=
27] and renal function, adjusting for race, sex, maternal smoking during pregnancy, and birth weight z-score.
Results:
Obesity was associated with higher systolic BP (
p
=0.03). Compared to adolescents with BMI <95
th
%ile, those with obesity had lower GFR (
β
: -14.68 mL/min/1.73 m
2
, 95% CI -26.8 to -2.55). Adjustment for covariates attenuated this relationship (
β
: -10.05 mL/min/1.73 m
2
, -21.12 to 1.03). Adolescents with obesity had a higher serum creatinine, but this did not reach statistical significance (
β
: 0.05 mg/dL, -0.01 to 0.11). There was no difference in the ACR (
β
: -0.05, -0.13 to 0.02).
Conclusions:
Obese adolescents born preterm with very low birth weight exhibit higher systolic BP and lower GFR compared to those with BMI <95
th
%ile, though the statistical significance of the relationship with GFR weakened after adjustment for possible confounders. Importantly, sex was a significant confounder that may influence the relationship between GFR and obesity, as female adolescents had significantly lower GFR than male adolescents. While obesity should be avoided, other factors should be considered that may contribute to worse renal function in adolescents born preterm with very low birth weight.

Abstract
Background:
Preterm birth increases the risk of cardiovascular disease, but the underlying mechanisms are not known. Prematurity may induce programming effects that differentially influence the renin-angiotensin (Ang) system (RAS), particularly suppression of the beneficial Ang-(1-7) axis. Patient factors such as sex and obesity may influence the degree of RAS programming. Therefore, we hypothesize that preterm birth is associated with alterations in the RAS in adolescence in a sex and adiposity-dependent manner.
Methods:
We evaluated a cohort of 175 adolescents born preterm and 51 term controls at age 14 years. We recorded systolic and diastolic BP z-scores, measured Ang II and Ang-(1-7) levels in plasma and urine, and calculated the peptide ratios. We applied generalized linear models to estimate the association between preterm birth and the RAS, adjusting for race, socioeconomic status, and maternal hypertension and smoking; the models were stratified by sex and overweight/obesity (body mass index ≥85
th
%ile for age and sex).
Results:
Mean systolic and diastolic BP z-scores were higher among those born preterm (
p
<0.001 and
p
=0.03, respectively). Relative to term birth, preterm birth was associated with an increased plasma ratio of Ang II to Ang-(1-7) (
β
: 4.42, 95% CI 1.52 to 7.32), decreased Ang II (
β
: -5.16 pmol/L, -10.28 to -0.04), decreased Ang-(1-7) (
β
: -5.38 pmol/L, -8.66 to -2.09), and a decreased urinary ratio of Ang II to Ang-(1-7) (
β
: -0.13, -0.26 to -0.003). In stratified analyses, female sex (
β
: -7.14 pmol/L, -11.03 to -3.24) and overweight/obesity (
β
: -8.21 pmol/L, -12.51 to -3.91) were associated with greater reductions in plasma Ang-(1-7). Overweight/obesity was associated with a greater increase in the ratio of plasma Ang II to Ang-(1-7) (
β
: +6.13, 0.58 to 11.68).
Conclusions:
Circulating Ang-(1-7) was lower relative to Ang II in adolescents born preterm. This suggests fetal RAS programming may contribute to the increased risk of cardiovascular disease in those born preterm. We note an important influence of sex in that the decrease in Ang-(1-7) is intensified in girls. Moreover, obesity may confer a second physiologic insult through a higher Ang II/Ang-(1-7) that exacerbates the risk of cardiovascular disease, including hypertension.

Abstract
INTRODUCTION High ultrafiltration (UF) rates can result in intradialytic hypotension and are associated with increased mortality. The effects of a weight-based UF rate limit on intradialytic hypotension and the potential for unwanted fluid weight gain and hospitalizations for volume overload are unknown. METHODS This retrospective cohort study examined 123 in-center hemodialysis patients at one facility who transitioned to 13 mL/kg/h maximum UF rates. Patients were studied for an 8 week UF rate limit exposure period and compared to the 8-week period immediately prior, during which the cohort served as its own historical control. The primary outcomes were frequency of intradialytic hypotension events and percentage of treatments with a hypotension event. FINDINGS The delivered UF rate was lower during the exposure compared to the baseline period (mean UF rate 7.90 ± 4.45 mL/kg/h vs. 8.92 ± 5.64 mL/kg/h; P = 0.0005). The risk of intradialytic hypotension was decreased during the exposure compared to baseline period (event rate per treatment 0.0569 vs. 0.0719, OR 0.78 [95% CI 0.62-1.00]; P = 0.0474), as was the risk of having a treatment with a hypotension event (percentage of treatments with event 5.2% vs. 6.8%, OR 0.75 [95% CI 0.58-0.96]; P = 0.0217). Subgroup analyses demonstrated that these findings were attributable to patients with high baseline UF rates. Statistically significant differences in all-cause or volume overload-related hospitalization were not observed during the exposure period. DISCUSSION A weight-based UF rate limit of 13 mL/kg/h was associated with a decrease in the rate of intradialytic hypotension events among in-center hemodialysis patients.

Abstract
Hip arthroscopy is a minimally invasive alternative to open hip surgery. Despite its minimally invasive nature, there can still be significant reported pain following these procedures. The impact of combined sciatic and lumbar plexus nerve blocks on postoperative pain scores and opioid consumption in patients undergoing hip arthroscopy was investigated. A retrospective analysis of 176 patients revealed that compared with patients with no preoperative peripheral nerve block, significant reductions in pain scores to 24 hours were reported and decreased opioid consumption during the post anesthesia care unit (PACU) stay was recorded; no significant differences in opioid consumption out to 24 hours were discovered. A subgroup analysis comparing two approaches to the sciatic nerve block in patients receiving the additional lumbar plexus nerve block failed to reveal a significant difference for this patient population. We conclude that peripheral nerve blockade can be a useful analgesic modality for patients undergoing hip arthroscopy.

Abstract
OBJECTIVES The HEART Pathway combines a decision aid and serial contemporary cardiac troponin I (cTnI) measures to achieve >99% sensitivity for major adverse cardiac events (MACE) at 30days and early discharge rates >20%. However, the impact of integrating high-sensitivity troponin (hs-cTn) measures into the HEART Pathway has yet to be determined. In this analysis we compare test characteristics of the HEART Pathway using hs-cTnI, hs-cTnT, or cTnI. DESIGN & METHODS A secondary analysis of participants enrolled in the HEART Pathway RCT was conducted. Each patient was risk stratified by the cTn-HEART Pathway (Siemens TnI-Ultra at 0- and 3-h) and a hs-cTn-HEART Pathway using hs-cTnI (Abbott) or hs-cTnT (Roche) at 3-h. The early discharge rate, sensitivity, specificity, and negative predictive value (NPV) for MACE (death, myocardial infarction, or coronary revascularization) at 30days were calculated. RESULTS hs-cTnI measures were available on 133 patients. MACE occurred in 11/133 (8%) of these patients. Test characteristics for the HEART Pathway using serial cTnI vs 3hour hs-cTnI were the same: sensitivity (100%, 95%CI: 72-100%), specificity (49%, 95%CI: 40-58%), NPV (100%, 95%CI: 94-100%), and early discharge rate (45%, 95%CI: 37-54%). The HEART Pathway using hs-cTnT missed one MACE event (myocardial infarction): sensitivity (91%, 95%CI: 59-100%), specificity (48%, 95%CI: 39-57%), NPV (98%, 95%CI: 91-100%), and early discharge rate (45%, 95%CI: 37-54%). CONCLUSIONS There was no difference in the test characteristics of the HEART Pathway whether using cTnI or hs-cTnI, with both achieving 100% sensitivity and NPV. Use of hs-cTnT with the HEART Pathway was associated with one missed MACE.

Abstract
Renal transplantation in children with ID is controversial. Acceptability of these children as candidates varies between programs. Limited outcome data in pediatric renal TXP recipients with cognitive impairment diminish their access to TXP. A retrospective chart review was performed of all children who underwent renal transplantation between January 1, 2002 and June 30, 2012 (N=72). Patients were divided into two groups, those with ID prior to transplantation (n=10) and those without (non-ID; n=62). Graft survival and BPAR episodes were compared between the two groups using Kaplan-Meier estimates. Graft survival rates at 3 years post-TXP were 100% in the ID group and 80% in the non-ID group (P=.13). Rates of BPAR at 3 years post-TXP were 10% in the ID group and 27% in the non-ID group (P=.29). Graft survival and acute rejection-free survival rates are similar between children with ID and those without. Based on midterm outcomes, there is no apparent contraindication to renal transplantation in pediatric patients with ID. Children with ID should be considered as TXP candidates provided that they have an adequate social support network.

Abstract
BACKGROUND Reduced heart rate variability (HRV) suggests autonomic imbalance in the control of heart rate and is associated with unfavorable cardiometabolic outcomes. We examined whether antenatal corticosteroid (ANCS) exposure had long-term programming effects on HRV in adolescents born with very low birth weight (VLBW). METHODS Follow-up study of a cohort of VLBW 14-y olds born between 1992 and 1996 with 50% exposed to ANCS. HRV in both the time and frequency domains using Nevrokard Software was determined from a 5-min electrocardiogram tracing. RESULTS HRV data from 89 (35 male, 53 non-black) exposed (ANCS+) and 77 (28 male, 29 non-black) unexposed (ANCS-) adolescents were analyzed. HRV did not differ between ANCS+ and ANCS- black participants. However, in non-black participants, a significant interaction between ANCS and sex was observed, with ANCS- females having significantly greater HRV than ANCS+ females and males, and ANCS- males for both time and frequency domain variables. CONCLUSION Among non-black adolescents born with VLBW, ANCS exposure is associated with reduced HRV with apparent sex-specificity. Reduced HRV has been associated with development of adverse cardiometabolic outcomes, thus supporting the need to monitor these outcomes in VLBW adolescents as they mature.

Abstract
CONTEXT Relative to European Americans, calcified atherosclerotic plaque (CP) is less prevalent and severe in African-Americans (AAs). OBJECTIVE Predictors of progression of CP in the aorta, carotid, and coronary arteries were examined in AAs over a mean 5.3 ± 1.4-year interval. DESIGN This is the African American-Diabetes Heart Study. SETTING A type 2 diabetes (T2D)-affected cohort was included. PARTICIPANTS A total of 300 unrelated AAs with T2D; 50% female, mean age 55 ± 9 years, baseline hemoglobin A1c 8.1 ± 1.8% was included. MAIN OUTCOME MEASURES Glycemic control, renal parameters, vitamin D, and computed tomography-derived measures of adiposity, vascular CP, and volumetric bone mineral density (vBMD) in lumbar and thoracic vertebrae were obtained at baseline and follow-up. RESULTS CP increased in incidence and quantity/mass in all three vascular beds over the 5-year study (P < .0001). Lower baseline lumbar and thoracic vBMD were associated with progression of abdominal aorta CP (P < .008), but not progression of carotid or coronary artery CP. Lower baseline estimated glomerular filtration rate was associated with progression of carotid artery CP (P = .0004), and higher baseline pericardial adipose volume was associated with progression of coronary artery (P = .001) and aorta (P = .0006) CP independent of body mass index. There was a trend for an inverse relationship between change in thoracic vBMD and change in aortic CP (P = .05). CONCLUSIONS In this longitudinal study, lower baseline thoracic and lumbar vBMD and estimated glomerular filtration rate and higher pericardial adipose volumes were associated with increases in CP in AAs with T2D. Changes in these variables and baseline levels and/or changes in glycemic control, albuminuria, and vitamin D were not significantly associated with progression of CP.

Abstract
INTRODUCTION The HEART Pathway is a diagnostic protocol designed to identify low-risk patients presenting to the emergency department with chest pain that are safe for early discharge. This protocol has been shown to significantly decrease health care resource utilization compared with usual care. However, the impact of the HEART Pathway on the cost of care has yet to be reported. METHODS AND RESULTS We performed a cost analysis of patients enrolled in the HEART Pathway trial, which randomized participants to either usual care or the HEART Pathway protocol. For low-risk patients, the HEART Pathway recommended early discharge from the emergency department without further testing. We compared index visit cost, cost at 30 days, and cardiac-related health care cost at 30 days between the 2 treatment arms. Costs for each patient included facility and professional costs. Cost at 30 days included total inpatient and outpatient costs, including the index encounter, regardless of etiology. Cardiac-related health care cost at 30 days included the index encounter and costs adjudicated to be cardiac-related within that period. Two hundred seventy of the 282 patients enrolled in the trial had cost data available for analysis. There was a significant reduction in cost for the HEART Pathway group at 30 days (median cost savings of $216 per individual), which was most evident in low-risk (Thrombolysis In Myocardial Infarction score of 0-1) patients (median savings of $253 per patient) and driven primarily by lower cardiac diagnostic costs in the HEART Pathway group. CONCLUSIONS Using the HEART Pathway as a decision aid for patients with undifferentiated chest pain resulted in significant cost savings.

Abstract
BACKGROUND Cytoreductive surgery (CS) with hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal metastases can alleviate symptoms and prolong survival at the expense of morbidity and quality of life (QoL). This study aimed to monitor QoL and outcomes before and after HIPEC. METHODS A prospective QoL trial of patients who underwent HIPEC for peritoneal metastases from 2000 to 2015 was conducted. The patients completed the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), the Functional Assessment of Cancer Therapy + Colon Subscale (FACT-C), the Brief Pain Inventory, the Center for Epidemiologic Studies Depression scale, and the Eastern Cooperative Oncology Group (ECOG) performance status at baseline, then 3, 6, 12, and 24 months after HIPEC. The trial outcome index (TOI) was analyzed. Proportional hazards modeled the effect of baseline QoL on survival. RESULTS The 598 patients (53.8 % female) in the study had a mean age of 53.3 years. The overall 1-year survival rate was 76.8 %, and the median survival period was 2.9 years. The findings showed a minor morbidity rate of 29.3 %, a major morbidity rate of 21.7 %, and a 30-day mortality rate of 3.5 %. The BPI (p < 0.0001) and worst pain (p = 0.004) increased at 3 months but returned to baseline at 6 months. After CS + HIPEC, FACT-C emotional well-being, SF-36 mental component score, and emotional health improved (all p < 0.001). Higher baseline FACT-General (hazard ratio [HR], 0.92; 95 % confidence interval [CI], 0.09-0.96), FACT-C (HR, 0.73; 95 % CI 0.65-0.83), physical well-being (HR, 0.71; 95 % CI 0.64-0.78), TOI (HR, 0.87; 95 % CI 0.84-0.91), and SF-36 vitality (HR, 0.88; 95 % CI 0.83-0.92) were associated with improved survival (all p < 0.001). Higher baseline BPI (HR, 1.1; 95 % CI 1.05-1.14; p < 0.0001), worst pain (HR, 1.06; 95 % CI 1.01-1.10; p = 0.01), and ECOG (HR, 1.74; 95 % CI 1.50-2.01; p < 0.0001) were associated with worse survival. CONCLUSIONS Although HIPEC is associated with morbidity and detriments to QoL, recovery with good overall QoL typically occurs at or before 6 months. Baseline QoL is associated with morbidity, mortality, and survival after HIPEC.

Abstract
Background:
While neonatal morbidity and mortality in preterm infants have improved dramatically, the long-term cardiovascular and renal consequences of prematurity are incompletely understood. Prematurity may induce programmed changes in the renin-angiotensin (Ang)-aldosterone system (RAAS), a key regulator of cardiovascular and renal function. Race and obesity influence the RAAS and may modify the effects of prematurity on the RAAS. We hypothesized that the RAAS differs by race and obesity in adolescents born prematurely with very low birth weight (VLBW).
Methods:
A cohort of 173 adolescents with VLBW was evaluated at age 14. We measured renin, aldosterone, Ang II, and Ang-(1-7) in the plasma; Ang II, Ang-(1-7), and creatinine in the urine; and we calculated the aldosterone/renin ratio and the Ang II/Ang-(1-7) ratios. We used general linear regression models to estimate the difference in the RAAS according to overweight/obesity (body mass index ≥85% for age and sex) and race, adjusting for confounding variables.
Results:
On unadjusted analyses as well as analyses adjusted for sex, antenatal corticosteroid exposure, and maternal hypertension, black race was associated with decreased urinary Ang-(1-7)/creatinine (adjusted estimate -0.18, 95% CI -0.36 to -0.01,
p
= 0.04) and decreased renin (-0.36, -0.68 to -0.05,
p
= 0.03). In analyses stratified by sex, black males, but not black females, had decreased renin (-0.63, -1.1 to -0.16,
p
= 0.01) and aldosterone (-0.61, -1.19 to -0.04,
p
= 0.04). Obesity was associated with increased urinary Ang II/(1-7) (0.29, 0.04 to 0.53,
p
= 0.02), decreased plasma Ang-(1-7) (-0.4, -0.8 to -0.002,
p
= 0.05), increased plasma Ang II (0.21, 0.03 to 0.39,
p
= 0.02), and increased plasma Ang II/(1-7) (0.61, 0.2 to 1.01,
p
= 0.004).
Conclusions:
In adolescents born with VLBW, there is racial variation in the RAAS. Black adolescents, especially males, have an altered renal RAAS and lower renin and aldosterone. Obesity is associated with a potentially deleterious alteration in the RAAS, with a shift in the renal and systemic RAAS towards Ang II and away from Ang-(1-7). These shifts in the RAAS associated with race and obesity may increase the risk of renal and cardiovascular disease in adolescents born with VLBW.

Abstract
Background:
Treatment with antenatal corticosteroids (ANCS) hastens fetal lung development and improves survival of infants born preterm, but the long-term effects of ANCS are not well described. Animal models suggest ANCS causes programmed alterations in renal maturation, including a decreased number of functional nephrons. Data in humans suggests that prematurity is associated with subsequent development of glomerular hyperfiltration and albuminuria as precursors of chronic kidney disease. We hypothesized that ANCS exposure alters renal function in adolescents born preterm.
Methods:
A cohort of 169 adolescents born prematurely, 91 of whom were exposed to ANCS, was evaluated at age 14. We measured plasma and urine creatinine (Cr) and urine albumin and calculated the estimated glomerular filtration rate (eGFR) and urine albumin-to-Cr ratio (ACR). The outcomes were albuminuria (urine ACR >30 mg/g Cr) and hyperfiltration (eGFR ≥147.5 mL/min/1.73 m
2
, the upper quintile of the cohort’s eGFR). We used multivariable logistic regression models to evaluate the association of ANCS exposure with renal outcomes, adjusting for confounding variables.
Results:
In unadjusted analyses and after adjustment for race, sex, and maternal hypertension, ANCS exposure was associated with a decreased likelihood of albuminuria (adjusted OR 0.33, 95% CI 0.12 to 0.91,
p
= 0.03). In unadjusted analysis ANCS was associated with an increased likelihood of hyperfiltration (unadjusted OR 3.17, 1.1 to 9.15,
p
= 0.03), and this relationship was only slightly attenuated after adjustment for confounding variables (
p
= 0.12).
Conclusions:
Adolescents born prematurely who were exposed to ANCS were less likely to exhibit albuminuria, but were more likely to have hyperfiltration. ANCS could affect renal function among adolescents born prematurely.

Abstract
BACKGROUND Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have shown variability in survival outcomes when used to treat peritoneal surface disease (PSD) from appendiceal and colorectal cancers. The primary goal of this study was to examine outcomes for high-grade appendiceal (HGA) and high-grade colonic primaries after CRS-HIPEC to determine if a significant difference exists between the two groups. METHODS A retrospective analysis of patients with peritoneal dissemination from appendiceal and colonic primaries were identified in a prospectively maintained database of 1,223 CRS-HIPEC procedures performed between 1991 and 2015. Patient demographics, performance status resection status, tumor grade, nodal status, morbidity, mortality, and survival were reviewed with biopsy-proven PSD being classified according to primary site. Univariate and multivariate analyses were performed, and outcomes compared. RESULTS The study identified 171 CRS-HIPEC procedures for 165 patients: 110 (66.7%) for HGA and 55 (33.3%) for high-grade colonic lesions. Observed median disease-free survival (DFS) and overall survival (OS) for both groups were the same at14.4 and 18 months, respectively. Median survival according to resection status for R0/R1, R2a, and R2b/c were 36, 15.6, and 8.4 months (P<0.0001). Median OS for those who received preoperative chemotherapy versus those who did not were 14.4 and 20.4 months, respectively (P=0.01). For those who received preoperative chemotherapy, no difference was apparent in the DFS interval (P=0.34). Multivariate predictors of OS included resection status (P<0.0001) and lymph node involvement (P=0.0005). CONCLUSIONS Preoperative chemotherapy offered no clear DFS or OS benefit, for HGA or high-grade colon cancer patients. Complete cytoreduction offered the greatest survival benefit to both groups with a correlating drop in survival to resection status. Outcomes for high grade appendiceal cancer are remarkably similar to colon cancer.

Abstract
PURPOSE This study highlights the trends and data points of interest in physician assistant (PA) applicant data over the first 10 years of the Central Application Service for Physician Assistants (CASPA) (2002-2011) and PA matriculant data over the last 5 years of that 10-year period (2007-2011). METHODS A retrospective study of data provided by applicants to all CASPA-participating PA programs between 2002 and 2011 was conducted. Applicant data analyzed over the 10-year period were provided by applicants and collected through an online CASPA applicant portal. Academic information was verified by CASPA staff through official transcript review. Matriculant data were obtained from CASPA-participating programs through the online CASPA admissions portal, which linked to applicant data in the CASPA applicant portal. RESULTS During the first 10 years of the CASPA service, the Physician Assistant Education Association experienced a 93% increase in the number of CASPA-participating programs and a 255% increase in the number of unique applicants identified through CASPA. Relatively constant trends were identified in the major demographic features (age, gender, ethnic composition, and disadvantaged status) and the academic data of applicants. Major demographic features of matriculants (2007-2011) also remained relatively constant, whereas trends in academic data of matriculants revealed an increasing total grade point average. CONCLUSION This 10-year comprehensive analysis of the CASPA data will benefit the profession by establishing a baseline of applicant characteristics. Ultimately, these data will help redefine recruitment strategies at program, state, and national levels by providing programs and national organizations with data needed to target applicants not previously included in recruitment activities.

Abstract
OBJECTIVES Accelerated diagnostic protocols (ADPs), such as the HEART Pathway, are gaining popularity in emergency departments (EDs) as tools used to risk stratify patients with acute chest pain. However, provider nonadherence may threaten the safety and effectiveness of ADPs. The objective of this study was to determine the frequency and impact of ADP nonadherence. METHODS A secondary analysis of participants enrolled in the HEART Pathway RCT was conducted. This trial enrolled 282 adult ED patients with symptoms concerning for acute coronary syndrome without ST-elevation on electrocardiogram. Patients randomized to the HEART Pathway (N = 141) were included in this analysis. Outcomes included index visit disposition, nonadherence, and major adverse cardiac events (MACEs) at 30 days. MACE was defined as death, myocardial infarction, or revascularization. Nonadherence was defined as: 1) undertesting-discharging a high-risk patient from the ED without objective testing (stress testing or coronary angiography) or 2) overtesting-admitting or obtaining objective testing on a low-risk patient. RESULTS Nonadherence to the HEART Pathway occurred in 28 of 141 patients (20%, 95% confidence interval [CI] = 14% to 27%). Overtesting occurred in 19 of 141 patients (13.5%, 95% CI = 8% to 19%) and undertesting in nine of 141 patients (6%, 95% CI = 3% to 12%). None of these 28 patients suffered MACE. The net effect of nonadherence was 10 additional admissions among patients identified as low-risk and appropriate for early discharge (absolute decrease in discharge rate of 7%, 95% CI = 3% to 13%). CONCLUSIONS Real-time use of the HEART Pathway resulted in a nonadherence rate of 20%, mostly due to overtesting. None of these patients had MACE within 30 days. Nonadherence decreased the discharge rate, attenuating the HEART Pathway's impact on health care use.

Abstract
BACKGROUND Fibroblast growth factor 23 (FGF23) is a phosphaturic hormone implicated in disorders of serum phosphorus concentration and vitamin D. The role of FGF23 in vascular calcification remains controversial. METHODS Relationships between FGF23 and coronary artery calcified atherosclerotic plaque (CAC), aortoiliac calcified plaque (CP), carotid artery CP, volumetric bone mineral density (vBMD), albuminuria, and estimated glomerular filtration rate (eGFR) were determined in 545 African Americans with type 2 diabetes (T2D) and preserved kidney function in African American-Diabetes Heart Study participants. Generalized linear models were fitted to test associations between FGF23 and cardiovascular, bone, and renal phenotypes, and change in measurements over time, adjusting for age, gender, African ancestry proportion, body mass index, diabetes duration, hemoglobin A1c, blood pressure, renin-angiotensin-system inhibitors, statins, calcium supplements, serum calcium, and serum phosphate. RESULTS The sample was 56.7% female with a mean (SD) age of 55.6 (9.6) years, diabetes duration of 10.3 (8.2) years, eGFR 90.9 (22.1) ml/min/1.73 m2, urine albumin:creatinine ratio (UACR) 151 (588) (median 13) mg/g, plasma FGF23 161 (157) RU/ml, and CAC 637 (1,179) mg. In fully adjusted models, FGF23 was negatively associated with eGFR (p < 0.0001) and positively associated with UACR (p < 0.0001) and CAC (p = 0.0006), but not with carotid CP or aortic CP. Baseline FGF23 concentration did not associate with changes in vBMD or CAC after a mean of 5.1 years follow-up. CONCLUSIONS Plasma FGF23 concentrations were independently associated with subclinical coronary artery disease, albuminuria, and kidney function in the understudied African American population with T2D. Findings support relationships between FGF23 and vascular calcification, but not between FGF23 and bone mineral density, in African Americans lacking advanced nephropathy.

Abstract
CONTEXT Vitamin D binding protein (DBP) is an important determinant of bioavailable vitamin D (BAVD) and may provide clues to racial variation in osteoporosis and atherosclerosis. OBJECTIVE The objective was to assess relationships between DBP, BAVD, 25-hydroxyvitamin D (25OHD), and 1,25 di-hydroxyvitamin D (1,25OH2D) with kidney, bone, adipose, and atherosclerosis phenotypes in African Americans with type 2 diabetes. DESIGN Cross-sectional (N = 545) and longitudinal (N = 288; mean 5.1 ± 0.9-year follow-up) relationships between vitamin D concentrations with renal phenotypes, vertebral bone mineral density, aorto-iliac, coronary artery, and carotid artery calcified plaque (CP), and adipose tissue volumes were studied. SETTING African American-Diabetes Heart Study. PATIENTS Participants were 56.7% female with mean ± standard deviation (sd) age 55.6 ± 9.6 years, diabetes duration 10.3 ± 8.2 years, and eGFR 90.9 ± 22.1 ml/min/1.73 m(2). INTERVENTIONS None. MAIN OUTCOMES AND MEASURES Associations tested between vitamin D and the previously mentioned phenotypes adjusting for age, sex, African ancestry proportion, diabetes duration, statins, smoking, changes in estimated glomerular filtration rate, body mass index, hemoglobin A1c, and blood pressure. RESULTS 1,25OH2D was inversely associated with change in coronary artery CP (parameter estimate [β] -0.005, standard error [SE] 0.002; P = .037), with a trend for change in carotid artery CP (β -0.007, SE 0.004; P = .074). Further adjustment for renin-aldosterone-system blockade revealed inverse association between 1,25OH2D and change in albuminuria (β -0.004, SE 0.002; P = .037). DBP, BAVD, and 25OHD did not associate significantly with changes in albuminuria, CP, or bone mineral density. BAVD was inversely associated with visceral, subcutaneous, intermuscular, and pericardial adipose volumes. CONCLUSIONS In contrast to BAVD and 25OHD, only 1,25OH2D levels were significantly and inversely associated with changes in subclinical atherosclerosis and albuminuria in African Americans, suggesting potential beneficial effects.

Abstract
BACKGROUND The HEART Pathway is a decision aid designed to identify emergency department patients with acute chest pain for early discharge. No randomized trials have compared the HEART Pathway with usual care. METHODS AND RESULTS Adult emergency department patients with symptoms related to acute coronary syndrome without ST-elevation on ECG (n=282) were randomized to the HEART Pathway or usual care. In the HEART Pathway arm, emergency department providers used the HEART score, a validated decision aid, and troponin measures at 0 and 3 hours to identify patients for early discharge. Usual care was based on American College of Cardiology/American Heart Association guidelines. The primary outcome, objective cardiac testing (stress testing or angiography), and secondary outcomes, index length of stay, early discharge, and major adverse cardiac events (death, myocardial infarction, or coronary revascularization), were assessed at 30 days by phone interview and record review. Participants had a mean age of 53 years, 16% had previous myocardial infarction, and 6% (95% confidence interval, 3.6%-9.5%) had major adverse cardiac events within 30 days of randomization. Compared with usual care, use of the HEART Pathway decreased objective cardiac testing at 30 days by 12.1% (68.8% versus 56.7%; P=0.048) and length of stay by 12 hours (9.9 versus 21.9 hours; P=0.013) and increased early discharges by 21.3% (39.7% versus 18.4%; P<0.001). No patients identified for early discharge had major adverse cardiac events within 30 days. CONCLUSIONS The HEART Pathway reduces objective cardiac testing during 30 days, shortens length of stay, and increases early discharges. These important efficiency gains occurred without any patients identified for early discharge suffering MACE at 30 days. CLINICAL TRIAL REGISTRATION URL: http://www.clinicaltrials.gov.

Abstract
HYPOTHESIS/INTRODUCTION Preeclampsia is associated with alterations in the maternal renin-angiotensin-aldosterone system (RAAS), increased blood pressure (BP), and cardiovascular risk in the offspring. We hypothesized that preeclampsia is associated with alterations in the RAAS in the offspring that persist into adolescence. MATERIALS AND METHODS We compared components of the circulating (n = 111) and renal (n = 160) RAAS in adolescents born prematurely with very low birth weight (VLBW) of preeclamptic (PreE) and normotensive (NoHTN) pregnancies. Multivariable linear regression was used to evaluate potential confounding and intermediate variables. Analyses were stratified by sex. RESULTS Adjusting for race and antenatal steroid exposure, male offspring of PreE mothers had higher circulating aldosterone than those of NoHTN mothers (adjusted mean difference = 109; 95% confidence limits: -9, 227 pmol/L). Further adjustment for current BMI attenuated this difference (adjusted mean difference: 93; 95% confidence limits: -30, 215 pmol/L). CONCLUSION Among male preterm VLBW infants, maternal preeclampsia is associated with increased circulating aldosterone level in adolescence, which appears to be mediated in part by higher BMI.

Abstract
BACKGROUND Liver resection has long been considered the standard of care for resectable colorectal hepatic metastases (HM). Patients with colorectal peritoneal surface disease (PSD) are now also being treated with aggressive therapy in the form of cytoreductive surgery (CS) and hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS A retrospective comparison of optimally-treated colorectal cancer patients with HM or PSD obtained from prospectively maintained databases (1991-2010). RESULTS Liver resection was performed on 179 patients with HM, while 93 PSD patients received a complete cytoreduction followed by HIPEC. Patients differed in terms of age, performance status, site of primary cancer, T stage, and the use of perioperative chemotherapy. Five-year overall survival for HM patients was 36 %, with a median survival of 46 months, compared with 26 % and 34 months in patients with PSD (p = 0.024). When stratified by resection status, R0 HM (n = 170) and R0 PSD (n = 48) patients had similar median survival (49 vs. 41 months; p = 0.39). Median survival following R1 resection was also similar among HM (n = 9) and PSD (n = 45) patients (28 vs. 23 months; p = 0.68). Multivariate analysis identified distinctly different independent prognostic factors between HM and PSD patients. Major morbidity was 21 and 23 % (p = 0.88), while mortality was 3.9 versus 5.4 % (p = 0.55) in the HM and PSD patients, respectively. CONCLUSION Colorectal HM and PSD are distinct biologic diseases with different presentations and unique prognostic factors. However, long-term survival following CS/HIPEC is comparable to liver resection when stratified by completeness of resection. Furthermore, perioperative morbidity and mortality are similar.

Abstract
BACKGROUND Peritoneal dissemination of abdominal malignancy (carcinomatosis) has a clinical course marked by bowel obstruction and death; it traditionally does not respond well to systemic therapy and has been approached with nihilism. To treat carcinomatosis, we use cytoreductive surgery (CS) with hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS A prospective database of patients has been maintained since 1992. Patients with biopsy-proven peritoneal surface disease were uniformly evaluated for, and treated with, CS and HIPEC. Patient demographics, performance status (Eastern Cooperative Oncology Group), resection status, and peritoneal surface disease were classified according to primary site. Univariate and multivariate analyses were performed. The experience was divided into quintiles and outcomes compared. RESULTS Between 1991 and 2013, a total of 1,000 patients underwent 1,097 HIPEC procedures. Mean age was 52.9 years and 53.1% were female. Primary tumor site was appendix in 472 (47.2%), colorectal in 248 (24.8%), mesothelioma in 72 (7.2%), ovary in 69 (6.9%), gastric in 46 (4.6%), and other in 97 (9.7%). Thirty-day mortality rate was 3.8% and median hospital stay was 8 days. Median overall survival was 29.4 months, with a 5-year survival rate of 32.5%. Factors correlating with improved survival on univariate and multivariate analysis (p ≤ 0.0001 for each) were preoperative performance status, primary tumor type, resection status, and experience quintile (p = 0.04). For the 5 quintiles, the 1- and 5-year survival rates, as well as the complete cytoreduction score (R0, R1, R2a) have increased, and transfusions, stoma creations, and complications have all decreased significantly (p < .001 for all). CONCLUSIONS This largest reported single-center experience with CS and HIPEC demonstrates that prognostic factors include primary site, performance status, completeness of resection, and institutional experience. The data show that outcomes have improved over time, with more complete cytoreduction and fewer serious complications, transfusions, and stomas. This was due to better patient selection and increased operative experience. Cytoreductive surgery with HIPEC represents a substantial improvement in outcomes compared with historical series, and shows that meaningful long-term survival is possible for selected carcinomatosis patients. Multi-institutional cooperative trials are needed to refine the use of CS and HIPEC.
