Abstract
BACKGROUND AND AIMS Substance use treatment (SUT) has shown to be effective in reducing self-reported offending; however, the association between SUT completion and criminal justice system (CJS) contact has been underexplored, especially in Latin America. This study aimed to estimate the association between SUT completion status and (1) any subsequent CJS contact and (2) CJS contact leading to imprisonment, at 1, 3 and 5 years post-discharge, in Chile. DESIGN Retrospective cohort study using multivariable survival analysis based on linked administrative data from 2010 to 2019. SETTING This study took place in Chile, where SUT is available at no cost through Chile's publicly funded health-care, and is provided in outpatient and inpatient modalities in public and private centres. PARTICIPANTS A total of 70 854 individuals received their first SUT from 2010 to 2019. They were mainly males (76.3%), and their main substance used at admission was cocaine paste (39.2%). MEASUREMENTS SUT completion status included completion, late dropout (≥ 3 months) and early dropout (< 3 months). Outcomes were (1) any CJS contact and (2) CJS contact leading to imprisonment after baseline treatment. We estimated the association between treatment completion and CJS contact through flexible parametric Royston-Parmar models while adjusting for several covariates. FINDINGS Those who completed SUT (27.2%) were less likely to have any CJS contact at 5 years post-SUT compared with those who dropped out late [with a gap of -9.5%, 95% confidence interval (CI) = -8.7, -10.3] and early (-11.2%, 95% CI = -10.1, -12.3). Also, those who completed SUT were less likely to have CJS contact leading to imprisonment at 5 years post-SUT compared with those who dropped out late (-2.6%, 95% CI = -2.2, -3.1) and early (-4.0%, 95% CI = -3.3, -4.6). These differences were also observed at 1 and 3 years post-SUT for each outcome. CONCLUSIONS In Chile, completion of substance use treatment appears to be associated with lower probabilities of both any criminal justice system contact and contact leading to imprisonment.

Abstract
Managing atrial fibrillation (AF) risk factors (RFs) improves ablation outcomes in obese patients. However, real-world data, including nonobese patients, are limited. This study examined the modifiable RFs of consecutive patients who underwent AF ablation at a tertiary care hospital from 2012 to 2019. The prespecified RFs included body mass index (BMI) ≥30 kg/m2, >5% fluctuation in BMI, obstructive sleep apnea with continuous positive airway pressure noncompliance, uncontrolled hypertension, uncontrolled diabetes, uncontrolled hyperlipidemia, tobacco use, alcohol use higher than the standard recommendation, and a diagnosis-to-ablation time (DAT) >1.5 years. The primary outcome was a composite of arrhythmia recurrence, cardiovascular admissions, and cardiovascular death. In this study, a high prevalence of preablation modifiable RFs was observed. More than 50% of the 724 study patients had uncontrolled hyperlipidemia, a BMI ≥30 mg/m2, a fluctuating BMI >5%, or a delayed DAT. During a median follow-up of 2.6 (interquartile range 1.4 to 4.6) years, 467 patients (64.5%) met the primary outcome. Independent RFs were a fluctuation in BMI >5% (hazard ratio [HR] 1.31, p = 0.008), diabetes with A1c ≥6.5% (HR 1.50, p = 0.014), and uncontrolled hyperlipidemia (HR 1.30, p = 0.005). A total of 264 patients (36.46%) had at least 2 of these predictive RFs, which was associated with a higher incidence of the primary outcome. Delayed DAT over 1.5 years did not alter the ablation outcome. In conclusion, substantial portions of patients who underwent AF ablation have potentially modifiable RFs that were not well controlled. Fluctuating BMI, diabetes with hemoglobin A1c ≥6.5%, and uncontrolled hyperlipidemia portend an increased risk of recurrent arrhythmia, cardiovascular hospitalizations, and mortality after ablation.

Abstract
BACKGROUND Harmful sexual behavior (HSB) displayed by children and young people under the age of 18 has been described as developmentally inappropriate, may be harmful towards self or others, or be abusive towards another child, young person, or adult. Early intervention and treatment completion are crucial to cease HSB, reduce impacts and address underlying issues for the child who has displayed HSB. Considerable shame attaches to seeking help for this stigmatized behavior which may result in dropout from support services. Understanding young people and caregivers' experiences of what facilitates or hinders their engagement with support services is therefore critical to preventing re-occurrence of HSB and keeping children safe. OBJECTIVE This article draws on the first-hand experience of young people and caregivers to address the question: What have they found helpful and unhelpful when engaging with services for harmful sexual behavior? PARTICIPANTS AND SETTING Participants were recruited from public health and youth justice services in the state of New South Wales, Australia. The 31 participants included 11 young people (aged 14 to 17) and 20 caregivers (parents, foster or kinship carers). METHODS Qualitative data were collected through individual semi-structured interviews, following which thematic analysis was conducted. RESULTS Data analysis identified three helpful responses: (1) non-judgmental recognition of crisis; (2) child-centred and family-focused orientation; and (3) multi-dimensional interventions. Unhelpful responses included: (1) closed doors (an inability to access a service) (2) stigmatization of HSB; and (3) reduced caregivers' autonomy. CONCLUSIONS Greater involvement of caregivers, non-stigmatizing language and coordinated responses between generalist and specialist services are needed to facilitate service engagement.

Abstract
Previous research has shown that virus infectivity can be dramatically reduced by radio frequency exposure in the gigahertz (GHz) frequency range. Given the worldwide SARS-CoV-2 pandemic, which has caused over 1 million deaths and has had a profound global economic impact, there is a need for a noninvasive technology that can reduce the transmission of virus among humans. RF is a potential wide area-of-effect viral decontamination technology that could be used in hospital rooms where patients are expelling virus, in grocery and convenience stores where local populations mix, and in first responder settings where rapid medical response spans many potentially infected locations within hours. In this study, we used bovine coronavirus (BCoV) as a surrogate of SARS-CoV-2 and exposed it to high peak power microwave (HPPM) pulses at four narrowband frequencies: 2.8, 5.6, 8.5, and 9.3 GHz. Exposures consisted of 2 µs pulses delivered at 500 Hz, with pulse counts varied by decades between 1 and 10,000. The peak field intensities (i.e. the instantaneous power density of each pulse) ranged between 0.6 and 6.5 MW/m2 , depending on the microwave frequency. The HPPM exposures were delivered to plastic coverslips containing BCoV dried on the surface. Hemagglutination (HA) and cytopathic effect analyses were performed 6 days after inoculation of host cells to assess viral infectivity. No change in viral infectivity was seen with increasing dose (pulse number) across the tested frequencies. Under all conditions tested, exposure did not reduce infectivity more than 1.0 log10. For the conditions studied, high peak power pulsed RF exposures in the 2-10 GHz range appear ineffective as a virucidal approach for hard surface decontamination. © 2023 Bioelectromagnetics Society.

Abstract
BACKGROUND The subcutaneous ICD (S-ICD) is a viable alternative to transvenous ICD and avoids intravascular complications in patients without a pacing indication. The outcomes of S-ICD implantation are uncertain in patients with prior sternotomy. OBJECTIVE We aim to compare the implant techniques and outcomes with S-ICD implantation in patients with and without prior sternotomy. METHODS Multicenter retrospective cohort study including adult patients with an S-ICD implanted between January 2014 and June 2020. Outcomes were compared between patients with and without prior sternotomy. RESULTS Among the 212 patients (49 ± 15 years old, 43% women, BMI 30 ± 8 kg/m2 , 68% primary prevention, 30% ischemic cardiomyopathy, LVEF median 30% IQR 25%-45%) who underwent S-ICD implantation, 47 (22%) had a prior sternotomy. There was no difference in the sensing vector (57% vs. 53% primary, p = 0.55), laterality of the S-ICD lead to the sternum (94% vs. 96% leftward, p = 0.54), or the defibrillation threshold (65 ± 1.4 J vs. 65 ± 0.8 J, p = 0.76) with versus without prior sternotomy. The frequency of 30-day complications was similar with and without prior sternotomy (n = 3/47 vs. n = 15/165, 6% vs. 9%, p = 0.56). Over a median follow-up of 28 months (IQR 10-49 months), the frequency of inappropriate shocks was similar between those with and without prior sternotomy (n = 3/47 and n = 16/165, 6% vs. 10%, p = 0.58). CONCLUSION Implantation of an S-ICD in patients with prior sternotomy is safe with a similar risk of 30-day complications and inappropriate ICD shocks as patients without prior sternotomy.

Abstract
Abstract
Background
Atrial fibrillation (AF) has become a global epidemic. Early catheter ablation and therapies modifying risk factors (RF) have been shown to improve outcomes of AF ablation. However, the time invested in pursuing risk factor modification may delay ablation, which could negate the procedural benefit.
Purpose
This study sought to investigate the prevalence and impact of potentially modifiable RF among AF patients undergoing catheter ablation in clinical practice.
Methods
This retrospective study included 724 consecutive patients undergoing AF ablation at a tertiary care center from 2012–2019. Pre-specified modifiable risks were examined, including the time from AF diagnosis to ablation, fluctuation/increase in BMI >5% prior to ablation, mean systolic/diastolic blood pressure >125/80 mmHg, obstructive sleep apnea with CPAP noncompliance, hyperlipidemia without statin therapy, tobacco use, excessive alcohol use, and diabetes mellitus with hemoglobin A1c (HbA1c) >6.5%. The primary outcome was a composite of recurrent atrial arrhythmias, cardiovascular (CV) hospitalizations and mortality following AF ablation. A multivariate analysis was performed.
Results
The mean age was 61±10 years old, 32.5% were female and 72.2% had persistent AF. Many study patients had modifiable RF, ranging from 4.7% with excessive alcohol use to 64.0% experiencing delayed AF ablation. The mean time from AF diagnosis to ablation was 4.7 years. During a mean follow-up of 1.6 years after ablation, 467 (64.5%) patients met the primary outcome. Independent RF for the primary outcome were an increase/fluctuation in BMI >5% (adjusted hazard ratio [AHR] 1.31, 95% confidence interval [CI] 1.07–1.60; P=0.008), diabetes with HbA1c >6.5% (AHR 1.50, 95% CI 1.09–2.03; P=0.014) and hyperlipidemia without statin therapy (AHR 1.30, 95% CI 1.08–1.57; P=0.005). Delayed AF ablation over 1.5 years did not alter the outcome, Figure 1.
Conclusion
Substantial portions of patients undergoing AF ablation have potentially modifiable RF. Increased or fluctuating BMI, diabetes with HbA1c >6.5%, and hyperlipidemia not treated with statin therapy portend an increased risk of recurrent atrial arrhythmia, CV hospitalizations and mortality. These findings underscore an importance pursuing RF management in patients with AF to reduce adverse outcomes after ablation.

Type of funding sources: None.
Background
Obesity is associated with greater risk of atrial fibrillation (AF) recurrence post-ablation and higher incidence of conduction delay compared to non-obese patients. Pre-ablation P-wave duration (PWD) and morphology (PWM) indicating interatrial delay are easily assessed in the clinic and may predict AF recurrence post-ablation in these patients.
Purpose
Evaluate the predictive value of PWD and PWM on AF recurrence post-ablation in obese patients.
Methods
Pre-ablation PWD and PWM (negative P-wave in lead II or III) were analyzed on consecutive patients with BMI ≥30 kg/m2 who underwent initial AF ablation from 2012–19. The primary outcome was recurrent AF after a 3-month post-ablation blanking period. Multivariate analysis adjusted for baseline characteristics was performed.
Results
For 205 patients (61.0±9.5 years old, 39.0% female), mean BMI was 36.9±5.7 kg/m2 and 71.7% had persistent AF pre-ablation. Recurrent AF post-ablation occurred in 115 (56.1%) during a median follow up of 491 (270, 1001) days. PWD >130 ms was significantly associated with higher AF recurrence (AHR of 1.62, 95%CI 1.04-2.57, p=0.03) after adjusting for age, persistent AF and left atrial volume index (LAVI). In a subgroup with LAVI <42 mL/m2 (n=112), PWD >130 ms and negative P-waves in lead II or III were independently associated with increased risk of recurrent AF (AHR 2.06, 95%CI 1.12-3.91; p=0.019 and AHR 1.94, 95% CI 1.00-3.56; p=0.05, respectively) (Figure 1).
Conclusion
AF recurred in >50% of obese patients within 1.5 years of ablation. Pre-ablation PWD >130 ms and negative P-waves in lead II or III independently predicted recurrent AF post-ablation in this cohort of obese patients. These easily assessed findings add predictive value to other risk factors.

Abstract
Background/Introduction
Obesity and atrial fibrillation (AF) coexist and share multiple cardiovascular risk factors. Lifestyle modifications can reduce AF burden in obese patients. However, the time invested in pursing lifestyle changes may delay AF ablation, which could negate the procedural benefit.
Purpose
To examine the effects of lifestyle modifications and the timing of catheter ablation on morbidly obese patients with AF.
Methods
This retrospective study included 217 consecutive AF patients with a body mass index (BMI) ≥35 kg/m2 undergoing AF ablation at a tertiary care center from 2012 to 2019. Modifiable risks were examined, including the time from AF diagnosis to ablation, fluctuation of BMI >5% or an increase in BMI >3% prior to ablation, mean systolic blood pressure >130 mmHg or diastolic blood pressure >80 mmHg, obstructive sleep apnea with CPAP noncompliance, hyperlipidemia without statin therapy, tobacco use, excessive alcohol use, and diabetes mellitus with hemoglobin A1c (HbA1c) ≥6.5%. The primary outcome was a composite of recurrent atrial arrhythmias and cardiovascular (CV) hospitalizations following AF ablation. A multivariate analysis adjusting for age, gender and modifiable risks was performed.
Results
The mean age was 61±9 years old, 58% were female and 45% had persistent AF. A substantial portion of the study patients had modifiable risk factors, ranging from 2.7% with excessive alcohol use to 67.3% experiencing delayed AF ablation, Figure 1. The median time from diagnosed AF to ablation was 1.3 years. During a mean follow-up of 2.9 years after AF ablation, 136 (62.7%) patients met the primary outcome. Only HbA1c ≥6.5% was an independent risk factor with adjusted hazard ratio of 1.57, 95% confidence interval 1.02–2.36, P=0.0412, Figure 2A. Delayed AF ablation did not alter the outcome, Figure 2B. There was no interaction between time of ablation and HbA1c ≥6.5% (P=0.67).
Conclusion
Substantial portions of morbidly obese patients undergoing AF ablation have potentially modifiable risk factors. Poor glycemic control with HbA1c ≥6.5% predicts an increased risk of recurrent atrial arrhythmias and CV hospitalizations, while delayed AF ablation does not. This finding underscores an importance of optimizing HbA1c in morbidly obese patients with AF to reduce adverse outcomes after ablation.

Abstract
Arrhythmia-induced cardiomyopathy secondary to frequent ventricular premature contractions is a well-studied phenomenon; however, there is a paucity of data showing a similar association with frequent atrial premature contractions (APCs). Early recognition and successful APC ablation can reverse left ventricular dysfunction in these patients. (Level of Difficulty: Beginner.).

Introduction
Catheter ablation (CA) of frequent premature ventricular contractions (PVC) is increasingly performed in older patients as the population ages.
Purpose
The purpose of this study was to assess the impact of age on procedural characteristics, safety and efficacy on PVC ablations.
Methods
Consecutive patients with symptomatic PVCs undergoing CA between 2015 and 2020 were evaluated. Acute ablation success was defined as the elimination of PVCs at the end of the procedure. Sustained success was defined as an elimination of symptoms, and ≥80% reduction of PVC burden determined by Holter-ECG during long-term follow. Patients were sub-grouped based on age (< 65 years vs. ≥ 65 years).
Results
A total of 114 patients were enrolled (median age 64 years, 71% males) and followed up for a median duration of 228 days. Baseline and procedural data were similar in both age groups. A left-sided origin of PVCs was more frequently observed in the elderly patient group compared to younger patients (83% vs. 67%, p = 0.04, Figure 1). The median procedure time was significantly shorter in elderly patients (160 min vs. 193 min, p = 0.02). The rates of both acute (86% vs. 92%, p = 0.32) and sustained success (70% vs. 71%, p = 0.90) were similar between groups. Complications rates (3.7%) did not differ between the two groups.
Conclusion
In a large series of patients with a variety of underlying arrhythmia substrates, similar rates of acute procedural success, complications, and ventricular arrhythmia-free-survival were observed after CA of PVCs. Older age alone should not be a reason to withhold CA of PVCs. Abstract Figure 1

Abstract
AIM To describe and test a new method that increases the conspicuity of a Hill-Sachs lesion on internal rotation (IR) radiographs. MATERIALS AND METHODS This study had institutional review board approval. A retrospective search for patients with a prior shoulder dislocation and a Hill-Sachs lesion documented on magnetic resonance imaging (MRI) was performed over a 10-year period identifying 256 test patients. In Part 1, the IR radiographs from test cases were randomised with controls, and three readers scored them independently for the defect. The readers were then taught the Broken Circle (BC) method and re-scored the radiographs. In Part 2, 15 cases of Hill-Sachs lesions that were missed by all readers in Part 1 were randomised with controls, and were shown to 25 radiology residents before (pre-test) and after (post-test) learning the BC method. A paired t-test was used to compare the differences in sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV). RESULTS In Part 1, the sensitivity increased 19.7% (54.1%-73.8%; p<0.05) and NPV increased 10.8% (62.5%-73.3%; p<0.01). In Part 2, post-test sensitivity for residents increased 16.3% (55.2%-71.5%; p<0.0001), accuracy increased 13.4% (64%-77.4%; p<0.0001), and NPV increased 13.3% (40.8%-54.1%; p<0.0001) independent of the level of training. The change in accuracy was also statistically significant for every individual class. CONCLUSION The BC method was an effective technique that facilitated detection of a Hill-Sachs lesion at all levels of training, and was useful as a teaching tool.

Abstract
Abstract
Background
Data on occurrence, management and outcomes of iatrogenic aortic dissections (IAD) as a complication of catheter ablation (CA) do not exist.
Purpose
To evaluate multicenter data on occurrence, management and outcomes of IAD as a complication of CA.
Methods
Data on occurrence, management and outcomes of documented vascular dissections from 10 centers were evaluated.
Results
IADs occurred in 7 patients (2 females, age 63 ± 8 years). Indications for CA were frequent premature ventricular complexes (PVC)/ventricular tachycardia (VT) in 6 patients (86%) and left-sided accessory pathway in the remaining one (14%). Hypertension was most frequent comorbidity (4 pts, 57%). All IADs occurred during retrograde advancement of ablation catheter. In the vast majority of patients creation of IAD during catheter advancement was not associated with any symptoms (6 pts, 86%). IAD was initially detected using trans-luminal angiogram in 5 (71%) and further confirmed using computed tomography (CT) (5 pts, 71%), conventional angiography (2 pts, 28%) and ultrasound (2 pts, 28%). One IAD was detected during CT scan performed for other indication after CA. There was one IAD-related death and IAD was evaluated post-mortem. Follow-up lasted 10 ± 19 months. Four patients were treated conservatively, one patient underwent descending aorta stenting and one femoral artery stenting.
Conclusions
IAD during CA is a rare but can be devastating. Early recognition can be difficult. Conservative management of IAD is an option of treatment.

Abstract
Abstract
Background
Estimated plasma volume (ePV) can be calculated from haematocrit and body weight, and has been shown to correlate with PV measured using 125Iodine labelled human serum albumin. Comparing a patient's ePV to ideal PV (iPV), an estimate of a patient's relative congestion, called PV status (PVS), is possible. Higher PVS is associated with increased mortality in patients with heart failure (HF), and has been proposed as a simple, cheap, and non-invasive way of assessing congestion.
Purpose
Whether PVS is associated with invasively measured markers of congestion is unknown. We calculated PVS in patients with HF who had right heart catheterisation (RHC), and assessed any correlation between PVS and invasive measures of congestion.
Methods
We calculated PVS in consecutive patients who had RHC performed as part of transplant assessment. iPV was calculated as: iPV = c × weight (kg) where c=39 in males and c=40 in females. ePV was calculated using subjects' haematocrit and weight as follows: ePV = (1 − haematocrit) × [a + (b × weight in kg)], where haematocrit is a fraction, a=1530 in males and a=864 in females, and b=41 in males and b=47.9 in females. PVS was calculated as: PVS = PVS = (ePV − iPV) /iPV × 100%. Correlation between PVS and invasive wedge pressure, mean right atrial (RA) pressure, and NTproBNP were made using Pearson correlation.
Results
PV indices and RHC data were available for 61 patients, 43 (71%) were male. Median age was 55 [IQR 48, 58] years. 20 (33%), 24 (39%), and 15 (25%) were NYHA association class II, III, and IV respectively. The median NTproBNP was 1390 [IQR 512, 3612] pg/ml and median ejection fraction was 29 [IQR 20, 35] %. The median PVS was −5.9% (IQR −12.5, −1.6]. Median wedge and mean-RA pressures were 14 [7, 21] and 4 [1, 8] mmHg, respectively. Correlation between mean RA pressure and PVS is shown in the figure. There was no correlation between PVS and mean RA pressure (r=0.12, p=0.34) or wedge pressure (r=0.01, p=0.92). There was a weak correlation between NTproBNP and PVS (r=0.31, p=0.01)
Correlation mean RA pressure and PVS
Conclusion
PVS did not correlate with the invasive measures of congestion, mean RA and wedge pressure, but was weakly correlated with NTproBNP. Although there were limited number of patients in this study, we question the conclusion that PVS is a marker of congestion, and whether it can be used clinically for this purpose.

Abstract
BACKGROUND Painful events are the leading cause of hospitalizations for patients with sickle cell disease. Individualized pain plans targeting patient-specific maximum opioid dosing may shorten hospitalization length and are recommended by national guidelines. Prior to implementing individualized sickle cell pain plans, we tested the hypothesis that a shorter time to achieve a maximum opioid dose would improve hospitalization outcomes. PROCEDURE Two-year IRB-approved, retrospective study of pediatric patients admitted for vaso-occlusive crisis (VOC). We recorded the emergency department admission time, order entry time for the maximum opioid dose during the hospitalization, and time of discharge orders. We categorized patients as infrequent if they required <3 admissions for VOC over two years and patients as frequent if they required ≥3 admissions for VOC over two years. To account for multiple admissions, generalized linear modeling was performed. RESULTS We identified 236 admissions for acute pain observed in 108 patients. Achieving an earlier maximum opioid dose was significantly associated with shorter length of hospitalization for frequent and infrequent pain patients (both P ≤ 0.0001). As total hospitalization length can be impacted by the time a maximum opioid order was placed, we also analyzed hospitalization length after the maximum opioid order was placed. Frequent pain patients who achieved earlier analgesia had a significantly shorter hospitalization from the time the maximum opioid order was placed (P = 0.03) while no association was found for infrequent pain patients (P = 0.84). CONCLUSIONS Early achievement of maximum analgesia improved hospitalization outcomes and warrant further investigation in prospective studies of individualized pain plans.

Abstract
PURPOSE Device infection is a serious complication of cardiac implantable electronic devices (CIED). Ensuring complete pocket closure can be time consuming, but remains vital to prevent infection. The Zip® Surgical Skin Closure (ZIP) is a noninvasive adhesive device applied to the skin as an alternative to subcuticular sutures for skin closure. We hypothesized that using this device would decrease pocket closure times without increasing the risk of pocket infections. This is a single center, retrospective cohort study to compare pocket closure times and infection rates between ZIP and standard suture for CIED pocket closure. METHODS Two separate groups of consecutive new intravenous implants, upgrades, and pulse generator replacements from October 2015 to April 2017 were included. A total of 175 patients were included, using either ZIP (n = 80) or suture (n = 95). Total procedure time (local anesthetic to dressing application) and pocket closure time (fascial suture to dressing application) were compared. Pocket infections were defined as infections leading to CIED extraction or wound dehiscence requiring repeat procedure. Statistical analysis was performed using chi square test and Student's t test. RESULTS Pocket closure time and procedure time were significantly shorter for the ZIP group (14.9 ± 6.8 vs 20.1 ± 11.09 min, p = 0.0003) and (65.02 ± 30.4 vs 83.83 ± 40.3 min, p = 0.0008), respectively. No pocket infections occurred in the Zip group, while the suture group had 2:1 wound dehiscence and 1 pocket infection. CONCLUSION The ZIP device resulted in significantly shorter pocket closure and procedure times without increasing device pocket infections.

Abstract
Fractional flow reserve (FFR) has been shown to improve clinical decision-making for revascularization in intermediate coronary stenosis in native coronary arteries of patients with stable coronary disease. However, its use for saphenous vein graft (SVG) lesions has not been well validated. We sought to determine the prognostic value of deferring intervention in lesions with FFR >0.8 in SVG lesions. Clinical, angiographic, and hemodynamic variables and long-term outcomes were recorded in consecutive patients in whom percutaneous coronary intervention was deferred based on an FFR >0.8 for intermediate native coronary artery or SVG stenosis. Thirty-three patients underwent FFR of SVG lesions and were compared with 532 patients who underwent native vessel FFR during the same period. There were no differences in age (66.6 [interquartile range, IQR 63 to 76] vs 65 years [IQR 61 to 70]; p = 0.12), diabetes (41% vs 50%; p = 0.35), or hypertension (94% vs 97%; p = 0.71). During a median follow-up of 3.2 years (IQR 1.7 to 4.6 years) major adverse cardiac event was significantly higher in SVG group (36% vs 21%; log rank p = 0.01). Similarly, the rate of target vessel failure was significantly higher in the SVG group (27% vs 14%; p = 0.01). Deferred SVG lesions had the worst survival free of target vessel failure compared with deferred native lesions in both patients with and without previous CABG. An SVG lesion was an independent predictor of major adverse cardiac events on Cox proportional hazards analysis (hazard ratio 2.26; confidence interval 1.19, 4.28; p = 0.01). In conclusion, nonischemic FFR carries a significantly worse prognosis in SVG compared with non-SVG lesions. Caution is warranted in utilizing FFR for clinical decision-making in SVG lesions.

Abstract
INTRODUCTION AND AIMS Although there has been significant investment in policies and programs aimed at preventing drug-related crime, there has been comparatively little effort dedicated to the validation the relevant research and evidence gathering tools. In this study, we aim to confirm the internal consistency of UNCOPE, developed by Hoffmann and colleagues, in the Australian context, as well as explore whether time in custody and prior custodial experience results in differential item functioning. DESIGN AND METHODS Data were derived from the Australian Institute of Criminology's Drug Use Monitoring in Australia Program in which the UNCOPE instrument had been administered with 15 454 detainees who reported illicit drug use in the past 12 months. Item response theory methods are used to explore the characteristics of all six items, while Multiple Indicators Multiple Causes and likelihood ratio differential item functioning test methods are used to explore differential item functioning. RESULTS Strong support is indicated for the internal consistency of the UNCOPE instrument. Modest differential functioning is identified for only one item, indicating that prolonged periods of detention prior to interview may influence the probability of endorsement for items that require introspection and reflection on drug-related neglect. These modest effects are unlikely to have any practical effect on the overall utility of UNCOPE. DISCUSSION AND CONCLUSIONS In these analyses, the item characteristics of UNCOPE appear consistent with results seen in the USA. Further, the modest differential item functioning identified for neglect (item N) has no practical impact on the overall functioning on UNCOPE. Criminal justice and drug policy researchers will be comforted by the absence of any substantial implementation or environmental bias.

Abstract
Vasocclusive pain crises are common among pediatric patients with sickle cell disease (SCD). Some patients with repeated pain crises develop chronic pain. We performed a retrospective cohort study of pediatric patients with SCD with chronic pain treated with methadone. We identified a significant reduction in pain hospitalizations following methadone treatment (0.35 ± 0.19 vs. 0.19 ± 0.17 hospitalizations/month, P = 0.016). In addition, we did not observe overt organ toxicity nor symptoms of opioid withdrawal during methadone wean. We suggest that methadone is safe and has some clinical benefit, which should be proven in prospective randomized trials for pediatric patients with SCD and chronic pain.

Abstract
Infants and children with hypophosphatasia (HPP) treated with asfotase alfa show improvement in bone mineralization and motor function, but it is unclear whether the medication can affect fracture healing in adult HPP patients. We present the course of fracture healing in two adults with HPP on enzyme replacement. Case 1 is a 41-year-old female with infantile-onset HPP who was wheelchair-bound due to a nonhealing tibial fragility fracture sustained 3 years before and also had nonhealing femoral pseudofracture sustained 17 years before starting asfotase alfa therapy in December 2015. One month after medication initiation, she underwent elective osteotomy of tibia and fibula with intramedullary nail fixation. After 3 months of enzyme replacement, she was full weight-bearing and radiographs demonstrated callus formation at osteotomy sites, and at 11 months of therapy, radiographs showed union of the osteotomies. By 11 months of asfotase alfa therapy, there was near resolution of the femoral pseudofracture without interval surgery at this site. Case 2 is a 61-year-old male who showed nonunion of a fragility fracture of the right femur 8 years prior, intramedullary nail fixation 6 years prior, and stress fracture of the left femoral diaphysis sustained 1 year before starting asfotase alfa in October 2015. A trial of teriparatide was unsuccessful in healing of these fractures. On asfotase alfa, radiographs revealed interval healing of the left femur fracture after 12 months and complete healing of the right femur fracture and near resolution of the left femur fracture after 16 months of medical therapy. These two adult patients with HPP showed significant clinical and radiographic improvements in a total of four recalcitrant fractures on enzyme replacement therapy with asfotase alfa. © 2018 The Authors.

Abstract
INTRODUCTION Intracranial haemorrhage in children with inherited bleeding disorders is a potentially life-threatening complication and presents a significant therapeutic challenge. AIM To define the characteristics, management and outcomes of intracranial haemorrhage presenting in UK children ≤16 years of age with inherited bleeding disorders from 2003 to 2015. METHOD Retrospective analysis of children treated at UK haemophilia centres. RESULTS Of 66 children presenting with Intracranial haemorrhage (ICH), 82% had haemophilia A or B, 3% VWD and 15% a rare IBD. The IBD was a severe phenotype in 91%. The rates of ICH were 6.4 and 4.2 per 1000 patient years for haemophilia A and B, respectively. Median age at presentation was 4 months (33% neonates; 91% children <2 years of age). In neonates, delivery was spontaneous vaginal (SV) in 11, instrumental in 6, caesarean in 4 and unknown in 1. In children with haemophilia, the risk of ICH after instrumental delivery was 10.6 times greater than after SV delivery. Trauma was more common in children >2 years (67%) than in children 1 month to 2 years (18%; P = .027). Prior to ICH, only 4.5% of children were on prophylaxis. 6% of haemophiliacs had an inhibitor. The median duration of initial replacement therapy was 15 days. Mortality was 13.5%. Neurological sequelae occurred in 39% of survivors, being more common following intracerebral bleeding. In haemophilia survivors, 52% subsequently developed a FVIII inhibitor. CONCLUSION Intracranial haemorrhage occurs most frequently in children with severe IBDs, during the first 2 years of life and in children not receiving prophylaxis. Intracranial haemorrhage often occurs without documented trauma.

Abstract
The Veterans Health Administration (VHA) is plagued by abnormally high no-show and cancellation rates that reduce the productivity and efficiency of its medical outpatient clinics. We address this issue by developing a dynamic scheduling system that utilizes mobile computing via geo-location data to estimate the likelihood of a patient arriving on time for a scheduled appointment. These likelihoods are used to update the clinic's schedule in real time. When a patient's arrival probability falls below a given threshold, the patient's appointment is canceled. This appointment is immediately reassigned to another patient drawn from a pool of patients who are actively seeking an appointment. The replacement patients are prioritized using their arrival probability. Real-world data were not available for this study, so synthetic patient data were generated to test the feasibility of the design. The method for predicting the arrival probability was verified on a real set of taxicab data. This study demonstrates that dynamic scheduling using geo-location data can reduce the number of unused appointments with minimal risk of double booking resulting from incorrect predictions. We acknowledge that there could be privacy concerns with regards to government possession of one's location and offer strategies for alleviating these concerns in our conclusion.

Abstract
BACKGROUND Universal screening for postpartum depression is recommended in many countries. Knowledge of whether the disclosure of depressive symptoms in the postpartum period differs across cultures could improve detection and provide new insights into the pathogenesis. Moreover, it is a necessary step to evaluate the universal use of screening instruments in research and clinical practice. In the current study we sought to assess whether the Edinburgh Postnatal Depression Scale (EPDS), the most widely used screening tool for postpartum depression, measures the same underlying construct across cultural groups in a large international dataset. METHOD Ordinal regression and measurement invariance were used to explore the association between culture, operationalized as education, ethnicity/race and continent, and endorsement of depressive symptoms using the EPDS on 8209 new mothers from Europe and the USA. RESULTS Education, but not ethnicity/race, influenced the reporting of postpartum depression [difference between robust comparative fit indexes (∆*CFI) 0.01), but not between European countries (∆*CFI < 0.01). CONCLUSIONS Investigators and clinicians should be aware of the potential differences in expression of phenotype of postpartum depression that women of different educational backgrounds may manifest. The increasing cultural heterogeneity of societies together with the tendency towards globalization requires a culturally sensitive approach to patients, research and policies, that takes into account, beyond rhetoric, the context of a person's experiences and the context in which the research is conducted.

Abstract
An aberrant meniscus attachment was found in the setting of an anterior cruciate ligament injury. An anomalous cordlike attachment ran from the anterior horn of the medial meniscus to the posterior horn of the lateral meniscus through the intercondylar notch. Surgeons should be aware of the anatomical variability in the knee in order to provide the best care for their patients.

Abstract
H5N1 highly pathogenic avian influenza (HPAI) virus causes high mortality of infected birds, with infection in multiple organs, including in feathers. Feathers have been proposed as samples for diagnosis of HPAI infection in birds, and this study is part of a broader investigation validating the use of feathers for diagnostic purposes. To understand and characterize the morphological basis for feather infection, sections from 7 different skin tracts of ducks and chickens infected with 3 different clades of H5N1 HPAI virus from Indonesia and Vietnam were examined histologically. Results showed that in ducks, lesions and viral antigen were mainly detected in the epidermis of feathers and follicles, whereas in chickens, they were mostly found in the dermis of these structures. Abundant viral antigen was found in nearly all the feathers examined from chickens, and there was no apparent difference between virus isolates or skin tracts in the proportion of feathers that were antigen positive. By immunohistochemistry, the majority of feathers from most skin tracts from ducks infected with a Vietnamese H5N1 HPAI virus contained abundant levels of viral antigen, while few feathers were antigen positive from ducks infected with 2 Indonesian viruses. These results support and inform the use of feathers for diagnostic detection of H5N1 HPAI virus in birds.

Abstract
The sensory organs for taste in chickens (Gallus sp.) are taste buds in the oral epithelium of the palate, base of the oral cavity, and posterior tongue. Although there is not a pan-taste cell marker that labels all chicken taste bud cells, α-Gustducin and Vimentin each label a subpopulation of taste bud cells. In the present study, we used both α-Gustducin and Vimentin to further characterize chicken taste buds at the embryonic and post-hatching stages (E17-P5). We found that both α-Gustducin and Vimentin label distinct and overlapping populations of, but not all, taste bud cells. A-Gustducin immunosignals were observed as early as E18 and were consistently distributed in early and mature taste buds in embryos and hatchlings. Vimentin immunoreactivity was initially sparse at the embryonic stages then became apparent in taste buds after hatch. In hatchlings, α-Gustducin and Vimentin immunosignals largely co-localized in taste buds. A small subset of taste bud cells were labeled by either α-Gustducin or Vimentin or were not labeled. Importantly, each of the markers was observed in all of the examined taste buds. Our data suggest that the early onset of α-Gustducin in taste buds might be important for enabling chickens to respond to taste stimuli immediately after hatch and that distinctive population of taste bud cells that are labeled by different molecular markers might represent different cell types or different phases of taste bud cells. Additionally, α-Gustducin and Vimentin can potentially be used as molecular markers of all chicken taste buds in whole mount tissue.

Abstract
Birds display remarkable diversity in the distribution and morphology of scales and feathers on their feet, yet the genetic and developmental mechanisms governing this diversity remain unknown. Domestic pigeons have striking variation in foot feathering within a single species, providing a tractable model to investigate the molecular basis of skin appendage differences. We found that feathered feet in pigeons result from a partial transformation from hindlimb to forelimb identity mediated by cis-regulatory changes in the genes encoding the hindlimb-specific transcription factor Pitx1 and forelimb-specific transcription factor Tbx5. We also found that ectopic expression of Tbx5 is associated with foot feathers in chickens, suggesting similar molecular pathways underlie phenotypic convergence between these two species. These results show how changes in expression of regional patterning genes can generate localized changes in organ fate and morphology, and provide viable molecular mechanisms for diversity in hindlimb scale and feather distribution.

Abstract
Sodium pentobarbital, a euthanasia drug, can persist in animal carcasses following euthanasia and can cause secondary toxicosis to animals that consume the remains. This experiment was conducted to observe the effects of composting on euthanized horse carcass degradation and sodium pentobarbital residues in compost material up to 367 d. Six separate compost bins were constructed on pastureland. Three bins served as the control while 3 served as the treatment. The carbonaceous material, or bulking agent, consisted of hardwood chips mixed with yard waste wetted to approximately 50% moisture content. Bulking agent was added to each bin at a depth of 0.46 m, creating the pad. A licensed veterinarian provided 6 horse carcasses for use in the experiment. These horses had required euthanasia for health reasons. All horses were weighed and then sedated with an intravenous injection of 8 mL of xylazine. After sedation the 3 horses in the treatment group were euthanized by intravenous injection of 60 mL of sodium pentobarbital. The 3 control group horses were anesthetized by intravenous injection of 15 mL of ketamine hydrochloride and then humanely euthanized by precise gunshot to the temporal lobe. Following euthanasia, each carcass was placed on the center of the pad and surrounded with 0.6 m of additional bulking agent. Serum and liver samples were obtained immediately following death. Compost samples were obtained on d 7, 14, 28, 56, 84, 129, 233, and 367 while soil samples were obtained on d -1 and 367. Each sample was analyzed for sodium pentobarbital concentration. Compost pile and ambient temperatures were also recorded. Composting successfully degraded soft tissue with only large bones remaining. Data illustrate that sodium pentobarbital was detectable up to 367 d in compost piles with no clear trend of concentration reduction. Drug residues were detected in soil samples indicating that sodium pentobarbital leached from the carcass and through the pad. These findings confirm the persistence of sodium pentobarbital from equine mortality compost piles and emphasize the importance of proper carcass management of animals euthanized with a barbiturate to reduce environmental impact and secondary toxicosis.
