Abstract
BACKGROUND Merkel cell carcinoma (MCC) is an aggressive and rare neuroendocrine tumor, accounting for less than 1% of skin cancers. Metastasis primarily manifests in the cervical lymph nodes but rarely affect the thyroid. METHODS We report a case of primary head and neck cutaneous MCC with metastasis to the thyroid gland. A review of the literature of MCC with thyroid metastasis was conducted. RESULTS We identified five cases of MCC with thyroid metastasis. Primary sites included the distal upper and lower extremities, axilla, buttock, and groin. Treatment courses varied including thyroidectomy, immunotherapy, and expectant palliative measures. Time from initial diagnosis to thyroid metastasis ranged from four months to four years. Tissue diagnosis was achieved in 5 of 6 cases. CONCLUSIONS MCC with thyroid metastasis is rare and likely represents aggressive disease. Despite advances in treatment and surveillance, outcomes for MCC remain poor. Ongoing research may establish predictors for treatment response.

Abstract
PURPOSE Determine the pediatric prevalence of keratoconus (KC) using Scheimpflug corneal tomography. METHODS A prospective observational study was done on subjects aged 3 to 18 years at the Princeton Vision Clinic, Chicago, IL. Scheimpflug tomography (Pentacam HR, OCULUS Optikgerate GmbH) scans (Belin/Ambrósio Enhanced Ectasia BAD3) yielded BAD Final D (Final D) and Back Elevation at the Thinnest Point (BETP) measurements. Criteria differentiating non-KC from KC suspects & KC were, Non-KC -Final D <2.00 in both eyes; KC suspect -Final D ≥2.00 and <3.00 in combination with BETP ≥18 μm for myopia and ≥28 μm for hyperopia/mixed astigmatism in at least one eye; and KC -Final D of ≥3.00 with BETP ≥18 μm for myopia or ≥28 μm for hyperopia/mixed astigmatism in at least one eye. Two thousand two hundred and six subjects were recorded, removing duplicate and poor-quality scans leaving 2007 subjects. RESULTS Of 2007 subjects, six were classified as KC -prevalence of 1:334, three subjects were KC suspects -prevalence of 1:669, and total prevalence of KC suspects and KC was 1:223. CONCLUSION The prevalence of KC in children is higher than previously reported, emphasizing the importance of sensitive screening for KC at its earliest manifestation as standard in pediatric comprehensive eye examinations.

Abstract
OBJECTIVE Opportunities exist to improve intraoperative communication and documentation of resection margin details. We instituted a "frozen section timeout" that centers around visualization of the paired resection specimen and surgical defect-facilitating effective, bidirectional exchange of information. METHODS We designed an interactive form for use during the "frozen section timeout" including annotated 3D virtual models of the resected specimen and surgical defect, plus a "line-item" table for primary and supplemental margin results. The "timeout" was conducted over a Zoom call between the operating room and frozen section laboratory. The form was simultaneously projected and discussed while all members of the surgical care team stopped activities. Nurses, co-surgeons, and all other members of the surgical team were encouraged to take part in this process. RESULTS Twenty-six frozen section timeouts were conducted during head and neck surgeries in the Department of Otolaryngology at Mount Sinai West Hospital. These timeouts were facilitated by the lead surgeon, and all other activities were halted to ensure that critical information was shared, documented, and agreed upon. During the timeout, the annotated specimen and defect scans were displayed, clearly demonstrating the at-risk margins and the corresponding location and breadth of supplemental margins harvested. CONCLUSION Incorporating a frozen section timeout can improve intraoperative communication, increase transparency, and potentially eliminate uncertainty regarding margin status and tumor clearance. Visualization of at-risk margins and the corresponding location and breadth of supplemental margins promises an unprecedented level of documentation and understanding. This novel technique can establish a new and improved standard of care. LEVEL OF EVIDENCE NA Laryngoscope, 134:725-731, 2024.

Abstract
OBJECTIVE(S) Despite advancements in imaging techniques and cytological analysis, plunging ranula remains a challenging surgical, radiologic, and pathologic phenomenon. Of the 18 patients we evaluated at our institution, we highlight three cases that illustrate the high rate of misleading imaging and cytological results when assessing plunging ranula. METHODS Imaging results, biopsy findings, operative techniques, and pathological reports were reviewed from patients who had either a preoperative or postoperative diagnosis of ranula and underwent surgery by a single head and neck surgeon at a tertiary care center. RESULTS Of the 18 identified patients, computed tomography was correct on preoperative imaging 73% of the time and magnetic resonance imaging was correct on preoperative imaging 71% of the time. Two patients underwent preoperative ultrasound and their ultrasound reports did not accurately diagnose the presence of a ranula. Two patients underwent preoperative fine needle aspiration biopsy due to inconclusive preoperative imaging, in which results suggested either a ranula or epidermal cyst. Both ultimately did not match the final pathology. Three of eighteen patients (17%) underwent an inappropriate initial surgery due to incorrect imaging diagnoses and/or biopsy findings. CONCLUSION Despite use of preoperative modalities to distinguish plunging ranula from other cystic floor of mouth lesions, surgeons must be aware that no workup modality is fully precise. The potential for revision surgery must be included in all preoperative discussions for presumed plunging ranula. LEVEL OF EVIDENCE 4 Laryngoscope, 2024.

Abstract
OBJECTIVES To report on baseline refractive and keratometric values and their correlation with tomographic characteristics of eyes with keratoconus (KC). METHODS Retrospective chart review of patients treated in a single-center cornea and refractive surgery practice. Baseline topographic measurements were reviewed for 1,012 keratoconic eyes of 586 patients between 2008 and 2018. The manifest refraction, thinnest pachymetry (P thin ), corneal astigmatism (K astig ), and the maximum (K max ), steep (K steep ), flat (K flat ), and mean (K mean ) keratometry were analyzed. The location of K max (x, y) was used to determine central (<1 mm), paracentral (1-3 mm), pericentral (3-5 mm), or peripheral (>5 mm) cone locations. RESULTS In the entire cohort, the mean manifest sphere was -2.2±4.4 diopters (D) and the cylinder was -3.2±2.3 D. In total, 48.6% of patients had against the rule (ATR) manifest astigmatism (M astig ). The average K astig was 3.8±2.7 D, and unlike the manifest axis, 50.2% of patients had with the rule (WTR) K astig . Patients with a K max less than 50 D had an M astig of -1.9±1.6 D, 45.9% of which was ATR M astig . With respect to baseline tomography measurements, K max , K steep , K flat , and K mean were 58.0±9.4, 50.6±6.5, 46.8±5.9, and 48.6±6.1 D, respectively. There was a weak correlation between K max and simulated keratometry (K steep , K flat , and K mean ) for patients with a K max less than 60 D. CONCLUSIONS Simulated keratometry is poorly correlated with KC severity until the disease is more severe. M astig ≥2 D and ATR M astig were correlated with KC at all levels of severity. M astig ≥2 D and ATR M astig may serve as a simple, inexpensive, and widely available indicator for topographic analysis to identify possible KC and suggest further workup; however, further prospective studies are needed to confirm its utility.

Abstract
BACKGROUND Multidisciplinary approaches to weight loss have been shown to improve outcomes in bariatric patients. Few studies have been performed assessing the utility and compliance of fitness tracking devices after bariatric surgery. We aim to determine whether use of an activity tracking device assists bariatric patients in improving postoperative weight loss behaviors. METHODS A fitness wearable was offered to patients undergoing bariatric surgery from 2019 to 2022. A telephone survey was conducted to elucidate the impact of the device on the patient's postoperative weight loss efforts 6 to 12 months after surgery. Weight loss outcomes of sleeve gastrectomy (SG) patients receiving the fitness wearable (FW) were compared to those of a group of SG patients who did not receive one (non-FW). RESULTS Thirty-seven patients were given a fitness wearable, 20 of whom responded to our telephone survey. Five patients reported not using the device and were excluded. 88.2% reported that using the device had a positive impact on their overall lifestyle. Patients felt that using the fitness wearable to keeping track of their progress helped them both to achieve short-term fitness goals and sustain them in the long run. From the patients that utilized the device, 44.4% of those that discontinued felt like it helped them build a routine that they maintained even after they were no longer using it. Demographic data between FW and non-FW groups (age, sex, CCI, initial BMI, and surgery BMI) did not differ significantly. The FW group trended towards greater %EWL at 1 year post-operation (65.2% versus 52.4%, p = 0.066) and had significantly greater %TWL at 1 year post-operation (30.3% versus 22.3%, p = 0.02). CONCLUSION The use of an activity tracking device enhances a patient's post-bariatric surgery experience, serving to keep patients informed and motivated, and leading to improved activity that may translate to better weight loss outcomes.

Abstract
BACKGROUND Enhanced recovery protocols have been developed to improve perioperative outcomes; however, there is ongoing concern for aspiration with recent oral intake in patients with obesity, who may be predisposed to impaired gastrointestinal motility and greater gastric volumes. We aim to study the safety of a 300-mL preoperative carbohydrate-loading drink preceding bariatric surgery. STUDY DESIGN Data were collected prospectively from patients undergoing primary bariatric surgery. All bariatric patients at our institution are prescribed a proton pump inhibitor for 4 weeks before surgery and undergo a screening preoperative esophagogastroduodenoscopy (EGD) before surgery with a traditional 8-hour fast (NOCARB), followed by an intraoperative day-of-operation EGD with carbohydrate loading (CARB) 2 to 4 hours before incision. Gastric volumes and pH are measured after being endoscopically suctioned via direct visualization during both settings. RESULTS We identified 203 patients: 94 patients (46.3%) in the CARB group and 109 patients (53.7%) in the NOCARB group. The patients were 82.3% female with a mean age of 42.8 years and average BMI of 41.7 kg/m 2 . There was no difference in gastric volume between NOCARB and CARB (17.0 vs 16.1 mL, p = 0.59). The NOCARB group had lower pH values than the CARB group (2.8 vs 3.8, p = 0.001). Subset analysis of 23 patients who had measurements on both screening and intraoperative EGD revealed lower gastric volumes in CARB patients (13.3 vs 18.3, p < 0.0001). CONCLUSIONS When included in an enhanced recovery protocol, proton pump inhibitor use and preoperative carbohydrate loading 2 to 4 hours before bariatric surgery does not increase aspiration risk based on gastric volumes and pH and should be strongly considered in all eligible bariatric patients.

Abstract
Deficient gamma oscillations in prefrontal cortex (PFC) of individuals with schizophrenia appear to involve impaired inhibitory drive from parvalbumin-expressing interneurons (PVIs). Inhibitory drive from PVIs is regulated, in part, by RNA binding fox-1 homolog 1 (Rbfox1). Rbfox1 is spliced into nuclear or cytoplasmic isoforms, which regulate alternative splicing or stability of their target transcripts, respectively. One major target of cytoplasmic Rbfox1 is vesicle associated membrane protein 1 (Vamp1). Vamp1 mediates GABA release probability from PVIs, and the loss of Rbfox1 reduces Vamp1 levels which in turn impairs cortical inhibition. In this study, we investigated if the Rbfox1-Vamp1 pathway is altered in PVIs in PFC of individuals with schizophrenia by utilizing a novel strategy that combines multi-label in situ hybridization and immunohistochemistry. In the PFC of 20 matched pairs of schizophrenia and comparison subjects, cytoplasmic Rbfox1 protein levels were significantly lower in PVIs in schizophrenia and this deficit was not attributable to potential methodological confounds or schizophrenia-associated co-occurring factors. In a subset of this cohort, Vamp1 mRNA levels in PVIs were also significantly lower in schizophrenia and were predicted by lower cytoplasmic Rbfox1 protein levels across individual PVIs. To investigate the functional impact of Rbfox1-Vamp1 alterations in schizophrenia, we simulated the effect of lower GABA release probability from PVIs on gamma power in a computational model network of pyramidal neurons and PVIs. Our simulations showed that lower GABA release probability reduces gamma power by disrupting network synchrony while minimally affecting network activity. Finally, lower GABA release probability synergistically interacted with lower strength of inhibition from PVIs in schizophrenia to reduce gamma power non-linearly. Together, our findings suggest that the Rbfox1-Vamp1 pathway in PVIs is impaired in schizophrenia and that this alteration likely contributes to deficient PFC gamma power in the illness.

Abstract
BACKGROUND Frozen section analysis of oral cancer specimens is ideal for assessing margin distances and depth of invasion (DOI); the latter impacts intraoperative decisions regarding elective neck dissection (END). Here, we show that intraoperative determination of worst pattern of invasion (WPOI), specifically WPOI-5, has a high level of accuracy. This relates to our demonstration herein that WPOI-5 predicts occult cervical metastases (OCM) for pT1 oral squamous carcinoma (OSC). METHODS The presence of OCM was correlated with WPOI in 228 patients with primary T1/T2/cN0 OSC undergoing resection and END. Concordance between intraoperative and final pathology WPOI determination was assessed on 51 cases of OSC. RESULTS WPOI-5 predicts OCM in pT1 patients, compared with WPOI-4/WPOI-3 (p < 0.0001). Most pT1 WPOI-5 tumors had DOI of 4-5 mm (24/59 or 40.7%). Only two pT1 WPOI-5 tumors had DOI < 4 mm (3.0 and 3.5 mm). If END were performed in this pT1 cohort for all WPOI-5 OSC patients regardless of DOI, OR all OSC patients with DOI ≥ 4 mm regardless of WPOI, then no OCM would be missed (p = 0.017, 100% sensitivity, 29% specificity, 77% positive predictive value, 23% negative predictive value). With respect to intraoperative WPOI-5 determination, the accuracy, sensitivity, and specificity was 92.16, 73.33, and 100.0%, respectively. CONCLUSIONS DOI ≥ 4 mm is the dominant predictor of OCM. For the rare WPOI-5 OSC with DOI < 4 mm, it is reasonable to suggest that surgeons perform END. WPOI-5 may be accurately determined intraoperatively. As microscopic instruction is needed to accurately assess WPOI-5, a teaching link is included in this manuscript.

Abstract
BACKGROUND Congenital diaphragmatic hernia (CDH) accounts for 8% of all major congenital anomalies. Neonates who are small for gestational age (SGA) generally have a poorer prognosis. We sought to identify risk factors and variables associated with outcomes in neonates with CDH who are SGA in comparison to neonates who are appropriate for gestational age (AGA). METHODS We used the multicenter Diaphragmatic Hernia Research & Exploration Advancing Molecular Science (DHREAMS) study to include neonates enrolled from 2005 to 2019. Chi-squared or Fisher's exact tests were used to compare categorical variables and t tests or Wilcoxon rank sum for continuous variables. Cox model analyzed time to event outcomes and logistic regression analyzed binary outcomes. RESULTS 589 neonates were examined. Ninety were SGA (15.3%). SGA patients were more likely to be female (p = 0.003), have a left sided CDH (p = 0.05), have additional congenital anomalies and be diagnosed with a genetic syndrome (p < 0.001). On initial single-variable analysis, SGA correlated with higher frequency of death prior to discharge (p < 0.001) and supplemental oxygen requirement at 28 days (p = 0.005). Twice as many SGA patients died before repair (12.2% vs 6.4%, p = 0.04). Using unadjusted Cox model, the risk of death prior to discharge among SGA patients was 1.57 times the risk for AGA patients (p = 0.029). There was no correlation between SGA and need for ECMO, pulmonary hypertensive medication at discharge or oxygen at discharge. After adjusting for confounding variables, SGA no longer correlated with mortality prior to discharge or incidence of unrepaired defects but remained significant for oxygen requirement at 28 days (p = 0.03). CONCLUSION Infants with CDH who are SGA have worse survival and poorer lung function than AGA infants. However, the outcome of SGA neonates is impacted by other factors including gestational age, genetic syndromes, and particularly congenital anomalies that contribute heavily to their poorer prognosis.

Abstract
Genome-wide association studies (GWASs) have identified hundreds of loci associated with Crohn's disease (CD). However, as with all complex diseases, robust identification of the genes dysregulated by noncoding variants typically driving GWAS discoveries has been challenging. Here, to complement GWASs and better define actionable biological targets, we analyzed sequence data from more than 30,000 patients with CD and 80,000 population controls. We directly implicate ten genes in general onset CD for the first time to our knowledge via association to coding variation, four of which lie within established CD GWAS loci. In nine instances, a single coding variant is significantly associated, and in the tenth, ATG4C, we see additionally a significantly increased burden of very rare coding variants in CD cases. In addition to reiterating the central role of innate and adaptive immune cells as well as autophagy in CD pathogenesis, these newly associated genes highlight the emerging role of mesenchymal cells in the development and maintenance of intestinal inflammation.

Background
Device complications, such as infection or lead dysfunction necessitating transvenous lead extraction (TLE) are continuously rising amongst patients with indwelling transvenous implantable cardioverter-defibrillator (ICD).
Objectives
Aim of this study was to characterize the procedural outcome and risk factors of patients with indwelling 1- and 2-chamber ICD undergoing TLE.
Methods
We conducted a subgroup analysis of all 1- and 2-chamber ICD patients in the GALLERY (GermAn Laser Lead Extraction RegistrY) database. Predictors for procedural failure and all-cause mortality were assessed.
Results
A total of 854 patients with ICD undergoing TLE were identified, who were younger (62.9±13.8 vs. 70.7±13.0 years; p<0.001), less likely to be female (20.8 vs. 27.1%; p<0.001) and had a higher proportion of patients with coronary artery disease (51.5 vs. 38.6%; p<0.001) and highly reduced ejection fraction (32.0 vs. 23.0%; p>0.001), when compared to non-ICD patients. Leading extraction indication was lead dysfunction (48.0 vs. 21.9%; p<0.001), followed by device-related infection (45.6 vs. 73.0%; p<0.001). There were no differences in overall procedural complications (4.3 vs. 4.3%; p=0.980), clinical success rate (97.9 vs. 97.8%; p=0.861) or procedure-related (0.8 vs. 0.5%; p=0.292) and all-cause mortality (3.4 vs. 3.7%; 0.742) between groups. Multivariate analysis revealed lead age≥10 years (OR:5.75, 95%CI:2.0-16.2; p=0.001) as independent predictor for procedural failure. Systemic infection as extraction indication (OR:9.57, 95%CI:2.2-42.4; p=0.003) and procedural complications (OR:8.0, 95%CI:2.8-23.3; p<0.001) were identified as risk factors for all-cause mortality. Predictors for systemic infection in ICD patients were atrial fibrillation (OR: 2.22, 95%CI: 1.51-3.27; p<0.001), diabetes mellitus (OR: 2.28, 95%CI: 1.59-3.25; p<0.001) and chronic kidney disease (OR: 2.0, 95%CI: 1.39-2.89; p<0.001).
Conclusions
Transvenous lead extraction is safe and efficacious in patients with 1- and 2-chamber ICD. Although lead dysfunction is the leading indication for extraction, systemic device-related infection is the main driver of all-cause mortality for ICD patients undergoing TLE.

Abstract
Abstract

Type of funding sources: None.
Background
The implantable cardioverter-defibrillator (ICD) and cardiac resynchronization therapy defibrillator (CRT-D) are well-established and essential therapeutic pillars for patients with heart failure and survivors of sudden cardiac death. The number of young patients receiving ICD or CRT-D has been increasing in the last decades. Understanding the key differences between the typically older ICD population and younger patients is paramount to optimized patient care.
Methods
The DEVICE registry prospectively enrolled patients undergoing ICD/CRT implantation or revision from 50 German centers between 2007–2014. Data on patient characteristics, procedural outcome, adverse events and mortality during the initial stay and follow-up was collected. All patients under the age of 45 years were identified and included into a comparative analysis with the remaining population.
Results
A total number of 4181 patients were enrolled into the registry, of which 236 patients (5.6%) were under the age of 45 years. Median age was 38.0 [31.0; 42.0] vs. 69.0 [60.0; 75.0] years, p<0.001), compared to older patients. Young patients were more likely to receive an ICD (91.5 vs. 69.4%, p<0.001), than CRT device and were less likely to suffer from non-cardiac comorbidities (20.3 vs. 67.4%, p<0.001). Coronary artery disease was less common in young patients (15.7 vs. 63.6%, p<0.001), whereas hypertrophic cardiomyopathy (11.0 vs. 2.5%, p<0.001) and primary cardiac electrical diseases (14.0 vs. 1.6%, p< 0.001) were encountered more often. Mean left-ventricular ejection fractions were 42.4±18.5 vs. 31.5±11.8%, respectively (p<0.001) with less young patients in NYHA functional class III/IV (19.5 vs. 45.3%, p<0.001). Primary symptom at presentation was chronic heart failure for older patients (19.5 vs. 34.8%, p<0.001) and survived sudden cardiac death (30.9 vs. 15.6%, p<0.001) for young patients. Thus, ICD for secondary prevention was more common in young patients (53.8 vs. 43.2%, p<0.001). There were no detectable differences in postoperative complications (3.0 vs. 4.1%, p=0.500) or in-hospital mortality (0.0 vs. 0.3%, p=1.000). Median follow-up time was 514 [398; 669] vs. 458 [391; 563] days (p=0.006). Device-associated complications requiring revision were more common in young patients (16.3 vs. 8.2%, p<0.001) and all-cause 1-year-mortality after implantation was lower (3.1 vs. 7.3%, p=0.029; HR 0.42, 95%CI: 0.19-0.94). Even though there was no difference in rates of rehospitalization between groups (32.1 vs. 32.4%, p=0.93), young patients were re-admitted more often for "cardiac" reasons (82.7 vs. 58.9%, p<0.001).
Conclusion
Rates for procedural complications and in-hospital mortality were very low and without differences between both age groups. However younger patients experienced a higher rate of postoperative complications requiring revision and had higher readmission rates for cardiac reasons, potentially due to a more active lifestyle.

Abstract
DISCLAIMER In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. PURPOSE Evidence-based guideline recommendations for vancomycin dosing recently shifted from a trough-based strategy to an area under the curve (AUC) approach. While several AUC dosing methods exist, the optimal approach has not been determined. Literature characterizing time requirements for various vancomycin dosing strategies remains limited. METHODS A time and motion study was conducted to measure the time spent by clinical pharmacists dosing vancomycin using an AUC nomogram. Pharmacists who dosed and monitored vancomycin for adult patients on the general medical ward (GMW) or intensive care unit (ICU) of a large academic medical center consented to study participation. Vulnerable patients and vancomycin orders for surgical infection prophylaxis were excluded. The primary outcome was the median amount of time clinical pharmacists dedicated to vancomycin-related clinical activities during an 8-hour weekday shift. Secondary outcomes included the proportion of patients prescribed vancomycin at the beginning of each shift and factors contributing to greater than average time spent on vancomycin-related responsibilities. RESULTS Seven clinical pharmacists collected data on 178 vancomycin orders. The estimated amount of time a clinical pharmacist spent on daily vancomycin responsibilities averaged 10.45 minutes (interquartile range [IQR], 6.94-15.8 minutes). The overall median time requirement per vancomycin assessment was 3.45 minutes (IQR, 1.95-6.7 minutes). The only factor independently associated with prolonged dosing time was follow-up dosing from a previous day. CONCLUSION The study elucidated time requirements associated with an AUC nomogram-based vancomycin dosing approach. This data could be used to compare time requirements associated with other existing vancomycin dosing strategies, which may help healthcare systems determine the optimal AUC dosing method for their specific practice model.

Abstract
Simulations and experiments at low Reynolds numbers have suggested that skin-friction drag generated by turbulent fluid flow over a surface can be decreased by oscillatory motion in the surface, with the amount of drag reduction predicted to decline with increasing Reynolds number. Here, we report direct measurements of substantial drag reduction achieved by using spanwise surface oscillations at high friction Reynolds numbers ([Formula: see text]) up to 12,800. The drag reduction occurs via two distinct physical pathways. The first pathway, as studied previously, involves actuating the surface at frequencies comparable to those of the small-scale eddies that dominate turbulence near the surface. We show that this strategy leads to drag reduction levels up to 25% at [Formula: see text] = 6,000, but with a power cost that exceeds any drag-reduction savings. The second pathway is new, and it involves actuation at frequencies comparable to those of the large-scale eddies farther from the surface. This alternate pathway produces drag reduction of 13% at [Formula: see text] = 12,800. It requires significantly less power and the drag reduction grows with Reynolds number, thereby opening up potential new avenues for reducing fuel consumption by transport vehicles and increasing power generation by wind turbines.

Abstract
Burkholderia cenocepacia is an opportunistic bacterial pathogen that causes severe pulmonary infections in cystic fibrosis and chronic granulomatous disease patients. B. cenocepacia can survive inside infected macrophages within the B. cenocepacia-containing vacuole (BcCV) and to elicit a severe inflammatory response. By inactivating the host macrophage Rho GTPases, the bacterial effector TecA causes depolymerization of the cortical actin cytoskeleton. In this study, we find that B. cenocepacia induces the formation of large cytosolic F-actin clusters in infected macrophages. Cluster formation requires the nucleation-promoting factor WASH, the Arp2/3 complex, and TecA. Inactivation of Rho GTPases by bacterial toxins is necessary and sufficient to induce the formation of the cytosolic actin clusters. By hijacking WASH and Arp2/3 activity, B. cenocepacia disrupts interactions with the endolysosomal system, thereby delaying the maturation of the BcCV.

Abstract
In this communication, we report on the genomic surveillance of SARS-CoV-2 using wastewater samples in Jefferson County, KY. In February 2021, we analyzed seven wastewater samples for SARS-CoV-2 genomic surveillance. Variants observed in smaller catchment areas, such as neighborhood manhole locations, were not necessarily consistent when compared to associated variant results in downstream treatment plants, suggesting catchment size or population could impact the ability to detect diversity.

Abstract
OBJECTIVES The objectives of this study were (1) to determine the rate of antibiotic prescribing at ambulatory clinics, and (2) to assess the concordance of antibiotic prescriptions with published guidelines and Food and Drug Administration-approved indications in terms of drug choices and dosing regimen. DESIGN Cross-sectional study. SETTING AND PARTICIPANTS Patients of all ages receiving at least 1 prescription during ambulatory visits in 2016 to 2017 were observed. OUTCOME MEASURES For each of the 3 clinic systems included in this study, oral antibiotic prescribing rates were estimated per patient and per ambulatory visit. Then, the concordance of oral antibiotic prescribing was assessed with respect to (1) choice of agent and (2) the dosing regimen by comparing it to the recommended therapeutic regimen (RTR). RESULTS A total of 284,348 patients receiving at least 1 prescription were included in the analysis. Between clinics, 17.4 to 43.7 per 100 patients received antibiotics. Of the antibiotics prescribed, 48.9% in Clinic A, 48.0% in Clinic B, and 60.7% in Clinic C were considered to be discordant in terms of drug choice. When the dosing regimen was taken into account in addition to the choice of agent, 72.6% in Clinic A, 76.7% in Clinic B, and 81.6% in Clinic C were discordant based on drug choice or dosing regimen. Of the prescriptions written with a discordant dosing regimen, 91.2% in Clinic A, 79.6% in Clinic B, and 91.0% in Clinic C were at a higher dosage than RTR. CONCLUSION Antibiotic prescribing rates vary by clinics, whereas discordant prescribing is consistently prevalent across clinics. More efforts should be put into ambulatory care to address antibiotic misuse problems, and our method could improve ambulatory antimicrobial stewardship programs.

Abstract
OnBehalf
GALLERY investigators
Background
The number of cardiac implantable electronic device (CIED)-associated complications such as infection, lead dysfunction or thrombotic events is continuously rising and thus making transvenous lead extraction (TLE) an ever more needed procedure in clinical practice today. Patients with abandoned leads represent a special cohort with a potentially higher susceptibility to CIED-related infections and vascular complications. Moreover, according to literature abandoned leads seem to be associated with more procedural complications and mortality during TLE.
Aim
The aim of this study was to provide an insight on safety, procedural outcome and risk prediction on pacemaker patients with abandoned leads undergoing TLE from the largest national laser-sheath registry to date.
Methods + Results:
We conducted a retrospective analysis of the GALLERY database, which collected 2533 patients undergoing TLE in Germany between 2013 and 2017. Out of 903 pacemaker patients, who underwent TLE, 226 patients (25.0%) with abandoned leads were identified. Those patients had a higher number of leads per patient (3.2 ± 0.8 vs. 1.9 ± 0.3; ns) and longer lead dwell-times (168.0 ± 89.7 vs. 123.0 ± 69.2 months; p < 0.0001) compared to pacemaker patients without abandoned leads. There were no differences in age (71.5 vs. 72.3 years; ns), body mass index (26.5 ± 4.5 vs. 26.78 ± 4.8 kg/m2; ns) or gender distribution (69.0 vs. 66.5% male; ns). Leading indication for TLE was device infection with no difference between groups (79.7 vs 77.8 %; ns). There were no differences in terms of pacemaker dependency, length of hospitalization or comorbidities. Patients with abandoned leads had longer procedure times (112.0 ± 69.0 vs. 86.4 ± 53.0 minutes; p < 0.0001) and a higher incidence of procedural complications (6.6 vs. 3.1%; p = 0.03), but there were no differences in neither procedural and clinical success rates (96.5 vs. 97.3%; ns), nor all-cause mortality (1.33 vs. 2.66%; ns). Multivariate logistic regression revealed abandoned leads (OR 2.1, CI 1.0-4.4, p = 0.04) and female gender (OR 2.4, CI 1.2-4.9, p = 0.02) as independent predictors for procedural complications. Systemic infection (OR 5.4, CI 2.0-14.8, p = 0.001) and chronic kidney disease (OR 4.0, CI 1.5-10.7, p = 0.007) were strong predictors for all-cause mortality in patients with indwelling pacemaker. Patient age > 75 years (OR 3.9, CI 2.7-5.6, p < 0.0001) and a lead dwell-time > 10 years (OR 1.6, CI 1.1-2.2, p = 0.01) were identified as risk factors for an infectious cause for TLE.
Conclusion
Abandoned leads are frequently encountered in pacemaker patients undergoing TLE and pose an important risk factor for procedural complications. Systemic CIED-related infections are the strongest driver of mortality in this patient cohort and urgently call for further improvements in early diagnosis and prevention.

Abstract
Abstract
Introduction
Initial download and use of sleep tracking is very high, but prolonged use is very low. Poor prolonged use may be attributable to several factors such as engagement, functionality, aesthetics, information, and recommendation. We appraised these five factors in 16 consumer- and research/medical- grade digital sleep devices.
Methods
Three reviewers independently assessed 16 consumer- and medical-grade sleep digital devices using the Mobile Application Rating Scale (MARS) App quality ratings, which measures engagement (engagement, entertainment, interest, customization, interactivity, target group), functionality (functionality, performance, ease of use, navigation, gestural design), aesthetics (layout, graphics, visual appeal), information (Accuracy. Goals, Quality of information, Quantity of information, Visual information, Credibility, and Evidence base) and recommended on a Likert scale, with 1- Inadequate to 5 Excellent. Each subcategory is rated on a 1-5 Likert scale which is summed for each category: engagement (30), functionality (25), aesthetics (15), information (35) and recommended (yes or no).
Results
Devices that had the highest engagement score were Fitbit (27), Apple Watch (27), Garmin (27), and Dreem 2 headband (25.5). Apple Watch (30) had highest score; while Fitbit (13), Apple Watch (13), Garmin (13), Samsung Gear (13) had highest aesthetic score. While for information, ActiGraph (35), SOMNOwatch plus (35), CleveMed SleepView Monitor (35), CleveMed Sapphire PSG (35), SOMNOscreen plus (35), Nox T3 Sleep Monitor (35) and Nox A1 PSG System (35) had the highest ratings. The Dreem 2 headband has the potential induce prolong use among users with and without sleep disorders, based on high scores on engagement (25.5), Functionality (20.5), and Information (26.5).
Conclusion
Consumer- and research-grade digital devices that measure sleep have varying levels of engagement, functionality, aesthetics, information and recommendations to facilitate prolong use. Consumer grade devices had higher engagement, functionality and aesthetics scores, while research grade devices had higher information and recommendation scores. If consumer- and research-grade devices are to have prolonged use, standardization is needed across the five MARS components.

Abstract
Abstract
Introduction
Emotional distress (ED) is associated with poor sleep. Research shows that minority populations experience greater vulnerabilities to both ED and poor sleep. Interventions such as relaxation training and behavioral therapy address this relationship but are not always successful. Research shows that physical activity (PA) is negatively associated with ED and positively associated with sleep duration. However, it is unclear whether PA attenuates the relationship between ED and sleep, and if this relationship differs by race/ethnicity.
Methods
We analyzed data from the 2005-2015 National Health Interview Survey (NHIS), a nationally representative dataset of 416,152 participants. ED, hours of PA per day, and average sleep duration were collected. Regression models with covariates (age, sex, employment status, BMI) were used to analyze the moderation effect of PA within sleep and ED. Regression models were stratified by race/ethnicity.
Results
261,686 participants (45,926 blacks, 17.55%, and 215,760 whites, 82.45%) responded with the required variables for analysis. 63% of participants reported at least some physical activity. The results of the regression showed that a significant amount of variance in ED stemmed from sleep duration; F (7, 121088) = 1,619.72, p < 0.001. PA was found to have a significant main effect, t(121,088) = 9.01, p= <0.001. There was a significant moderation effect of PA, t(121088) =7.26, p < 0.001. Stratification showed that the moderation effect of PA was not significant among blacks t(121,088) = -1.45, p=0.149 and significant among whites b = -.08, t(101,754) = -7.82, p < 0.001.
Conclusion
The present study found support for moderation of PA in the sleep-ED relationship. However, it found that blacks do not experience the same benefits of PA in this relationship as whites. Further research should be performed to understand the connection of PA to sleep duration and ED.

Abstract
Recent national guidelines recommend genetic risk assessment for all patients diagnosed with pancreatic cancer, yet individuals with pancreatic cancer obtain genetic testing at suboptimal rates. Both patient and provider factors play a role in adherence to genetic testing recommendations. The purpose of this study was to understand health care provider perspectives of caring for patients with inherited pancreatic cancer risk. The study was a cross-sectional mixed method study utilizing a qualitative interview and a survey. The study sample included health care providers who provide care for patients with pancreatic cancer or inherited risk. Qualitative data were analyzed using content analysis, while quantitative data were summarized using descriptive statistics. Thirty participants had complete interview data and 29 completed a survey. The sample was comprised of physicians (n = 17), genetic counselors (n = 6), nurses (n = 3), and social workers (n = 3). Respondents were less confident in their ability to identify patients with inherited pancreatic cancer risk compared with other hereditary cancer syndromes. Several challenges were identified including the pancreatic cancer illness trajectory; lack of evidence-based practice guidelines; difficulty interpreting genetic test results; and difficulty following up on referrals. Participants perceived a lack of educational resources for patients with inherited pancreatic cancer risk. Health care providers who care for individuals with inherited pancreatic cancer risk face challenges that are distinct from those encountered during the care of individuals for other hereditary cancers. There is a need for additional resources at the patient-, provider-, and system-level.

Abstract
Abstract
BACKGROUND
Glioblastoma is a disease with very poor outcome. Most patients underwent maximal safe resection, especially focusing in the preservation of motor and language function. However, many caregivers were suffered from the blockage of emotion communication with patients. So the definition of maximal safe resection must include the preservation of cognition and mentalizing of patients. Here we present the experience of brain mapping in awake surgery to preserve mentalizing.
MATERIAL AND METHODS
A 61-year-old male patient with headache was transferred to our hospital because of brain tumor on CT scan checked in another hospital. On the initial MRI, multi-septate cystic tumor was shown on left medial prefrontal area. The patient was recommended the surgical resection, but patient discharged with the denial of the operation. Ten days later, patient visited our hospital again with slowness of response by the enlargement of tumor size. The tumor extensively involved left cingulum and corpus callosum at anterior part. On diffusion tensor image, tumor located at mediosuperior part of inferior fronto-occipital fasciculus (IFOF). The patient showed deficit of visual and verbal memory, generative naming ability, and phonemic generative naming ability on preoperative neuropsychological test (SNSB-II). Pyramid and palm tree test (PPTT) and ‘Reading the Mind in the Eyes’ test (RMET) were also performed to evaluate the semantic association function and mentalizing preoperatively.
RESULTS
The patient underwent awake surgery with asleep-awake-asleep technique. The tumor was resected until identification of incorrect response to PPTT or RMET on subcortical stimulation (Ojeman stimulator, 1.5mA, 60Hz, biphasic). The histopathologic diagnosis was glioblastoma. Small part of tumor was remained on cingulum, but patient was discharged without change of mentalizing.
CONCLUSION
Although the patients with glioblastomas show poor outcome, we think that it is important to consider the cognition and mentalizing of patients for emotion communication with caregivers. With awake surgery, mentalizing can be preserved in selective patients.

Abstract
BACKGROUND People discharged from in-patient psychiatric facilities have highly elevated rates of suicide, and there is increasing concern about natural mortality among the seriously mentally ill. METHOD A meta-analysis of English-language, peer-reviewed longitudinal studies of mortality among patients discharged from in-patient psychiatric facilities was conducted using papers published in MEDLINE, PsycINFO or EMBASE (from 1 January 1960 to 1 April 2018) located using the terms ((suicid*).ti AND (hospital OR discharg* OR inpatient OR in-patient OR admit*)).ab and ((mortality OR outcome* OR death*) AND (psych* OR mental*)).ti AND (admit* OR admis* OR hospital* OR inpatient* OR in-patient* OR discharg*).ab. Pooled mortality rates for aggregated natural and unnatural causes, and the specific causes of suicide, accident, homicide, vascular, neoplastic, respiratory, gastrointestinal, infectious and metabolic death were calculated using a random-effects meta-analytic model. Between-study heterogeneity was investigated using subgroup analysis and metaregression. RESULTS The pooled natural death rate of 1128 per 100 000 person-years exceeded the pooled unnatural deaths of 479 per 100 000 person-year among studies with varying periods of follow-up. Natural deaths significantly exceeded unnatural deaths among studies with a mean follow-up of longer than 2 years, and vascular deaths exceeded suicide deaths among studies with mean period of follow-up of 5 years or longer. CONCLUSION Suicide may be the largest single cause of death in the short term after discharge from in-patient psychiatric facilities but vascular disease is the major cause of mortality in the medium- and long-term.

Abstract
OBJECTIVE To quantify the suicide rate among people discharged from non-psychiatric settings after presentations with suicidal thoughts or behaviours. METHOD Meta-analysis of studies reporting suicide deaths among people with suicidal thoughts or behaviours after discharge from emergency departments or the medical or surgical wards of general hospitals. RESULTS A total of 115 studies reported 167 cohorts and 3747 suicide deaths among 248 005 patients during 1 263 727 person-years. The pooled suicide rate postdischarge was 483 suicide deaths per 100 000 person-years (95% confidence interval (CI) 445-520, prediction interval (PI) 200-770) with high between-sample heterogeneity (I2 = 92). The suicide rate was highest in the first year postdischarge (851 per 100 000 person-years) but remained elevated in the long term. Suicide rates were elevated among samples of men (716 per 100 000 person-years) and older people (799 per 100 000 person-years) but were lower in samples of younger people (107 per 100 000 person-years) and among studies published between 2010 and 2018 (329 per 100 000 person-years). CONCLUSIONS People with suicidal thoughts or behaviours who are discharged from non-psychiatric settings have highly elevated rates of suicide despite a clinically meaningful decline in these suicide rates in recent decades.

Abstract
OBJECTIVE To assess the magnitude of suicide rates in the first week and first month postdischarge following psychiatric hospitalisation. DESIGN Meta-analysis of relevant English-language, peer-reviewed papers published in MEDLINE, PsycINFO or Embase between 01 January 1945 and 31 March 2017 and supplemented by hand searching and personal communication. A generalised linear effects model was fitted to the number of suicides, with a Poisson distribution, log link and log of person years as an offset. A random effects model was used to calculate the overall pooled rates and within subgroups in sensitivity analyses. OUTCOME MEASURES Suicides per 100 000 person years in the first week and the first month after discharge from psychiatric hospitalisation. RESULTS Thirty-four included papers comprised 29 studies that reported suicides in the first month postdischarge (3551 suicides during 222 546 patient years) and 24 studies that reported suicides in the first week postdischarge (1928 suicides during 60 880 patient years). The pooled estimate of the suicide rate in the first month postdischarge suicide was 2060 per 100 000 person years (95% CI=1300 to 3280, I2=90). The pooled estimate of the suicide rate in the first week postdischarge suicide was 2950 suicides per 100 000 person years (95% CI=1740 to 5000, I2=88). Eight studies that were included after personal communication had lower pooled rates of suicide than studies included after data extraction and there was evidence of publication bias towards papers reporting a higher rate of postdischarge suicide. CONCLUSION Acknowledging the presence of marked heterogeneity between studies and the likelihood of bias towards publication of studies reporting a higher postdischarge suicide rate, the first week and first month postdischarge following psychiatric hospitalisation are periods of extraordinary suicide risk. Short-term follow-up of discharged patients should be augmented with greater focus on safe transition from hospital to community care.

Abstract
Background The long-term natural history of microscopic colitis (MC) (collagenous colitis (CC), lymphocytic colitis (LC)), traditionally considered relapsing but non-progressive diseases, is poorly defined. Whether persistent histologic inflammation in such diseases is associated with an increased risk of colorectal neoplasia (CRN) or extracolonic cancers has not been robustly established. Methods This retrospective cohort included diagnosed with MC at a referral center. Rates of CRN and extracolonic cancer were compared to patients undergoing screening colonoscopy (n = 306) and to the United States population using data from the Surveillance, Epidemiology, and End-Results (SEER) program. Standardized incidence ratios (SIR) and 95% confidence intervals were calculated and multivariable regression models used to identify the effect of MC diagnosis and severity on cancer risk. Results Our study included 221 patients with microscopic colitis (112 CC, 109 LC) among whom 77% were women. Compared to the colonoscopy control population, MC was associated with similar odds of tubular adenoma (Odds ratio (OR) 1.07, 95% CI 0.69–1.66) or villous adenoma (OR 1.26, 95% CI 0.17–9.42). Compared to patients with a single episode of MC, those with 2 or more episodes had similar risk of colon cancer (OR 0.83, 95% CI 0.20–3.39) or tubular adenoma (OR 1.49 95% CI 0.83–2.67). We also identified no statistical increase in the rates of cancer in the MC population compared to US-SEER data. Conclusion Microscopic colitis was not associated with increased risk of CRN and extracolonic cancers when compared to controls undergoing colonoscopy or the US SEER population.

Abstract
Assessment of changes in DNA methylation (DNA-m) has the potential to identify adverse environmental exposures. To examine DNA-m among a subset of participants (n = 369) in the Isle of Wight birth cohort who reported variable near resident traffic frequencies. We used self-reported frequencies of heavy vehicles passing by the homes of study subjects as a proxy measure for TRAP, which were: never, seldom, 10 per day, 1-9 per hour and >10 per hour. Methylation of cytosine-phosphate-guanine (CpG) dinucleotide sequences in the DNA was assessed from blood samples collected at age 18 years (n = 369) in the F1 generation. We conducted an epigenome wide association study to examine CpGs related to the frequency of heavy vehicles passing by subjects' homes, and employed multiple linear regression models to assess potential associations. We repeated some of these analysis in the F2 generation (n = 140). Thirty-five CpG sites were associated with heavy vehicular traffic. After adjusting for confounders, we found 23 CpGs that were more methylated, and 11 CpGs that were less methylated with increasing heavy vehicular traffic frequency among all subjects. In the F2 generation, 2 of 31 CpGs were associated with traffic frequencies and the direction of the effect was the same as in the F1 subset while differential methylation of 7 of 31 CpG sites correlated with gene expression. Our findings reveal differences in DNA-m in participants who reported higher heavy vehicular traffic frequencies when compared to participants who reported lower frequencies.

Abstract
BACKGROUND TARDOX is a Phase I single center study of ultrasound triggered targeted drug delivery in adult oncology patients with incurable liver tumours. This proof of concept study is designed to demonstrate the safety and feasibility of targeted drug release and enhanced delivery of doxorubicin from thermally sensitive liposomes (ThermoDox®) triggered by mild hyperthermia induced by focused ultrasound in liver tumours. A key feature of the study is the direct quantification of the doxorubicin concentration before and after ultrasound exposure from tumour biopsies, using high performance liquid chromatography (HPLC). METHODS/DESIGN The study is conducted in two parts: Part 1 includes minimally-invasive thermometry via a thermistor or thermocouple implanted through the biopsy co-axial needle core, to confirm ultrasound-mediated hyperthermia, whilst Part 2 is carried out without invasive thermometry, to more closely mimic the ultimately intended clinical implementation of the technique. Whilst under a general anaesthetic, adult patients with incurable confirmed hepatic primary or secondary (metastatic) tumours receive a single cycle of ThermoDox®, immediately followed by ultrasound-mediated hyperthermia in a single target liver tumour. For each patient in Part 1, the HPLC-derived total doxorubicin concentration in the ultrasound-treated tumour is directly compared to the concentration before ultrasound exposure in that same tumour. For each patient in Part 2, as the tumour biopsy taken before ultrasound exposure is not available, the mean of those Part 1 tumour concentrations is used as the comparator. Success of the study requires at least a two-fold increase in the total intratumoural doxorubicin concentration, or final concentrations over 10 μg/g, in at least 50% of all patients receiving the drug, where tissue samples are evaluable by HPLC. Secondary outcome measures evaluate safety and feasibility of the intervention. Radiological response in the target tumour and control liver tumours are analysed as a tertiary outcome measure, in addition to plasma pharmacokinetics, fluorescence microscopy and immunohistochemistry of the biopsy samples. DISCUSSION If this early phase study can demonstrate that ultrasound-mediated hyperthermia can effectively enhance the delivery and penetration of chemotherapy agents intratumorally, it could enable application of the technique to enhance therapeutic outcomes across a broad range of drug classes to treat solid tumours.

Abstract
AbstractScreen climbing games have made a new category of gaming experience between a human climber and a virtual game projected onto an artificial climbing wall. Here, climbing motion recognition is required to interact with the game. In existing climbing games, motion recognition is based on a simple calculation using the depth difference between the climber’s body area and the climbing wall. However, using the body area in this way is devoid of anatomical information; thus the gaming system cannot recognize which part, or parts, of the climber’s body is in contact with the artificial climbing wall. In this paper, we present a climbing motion recognition method using anatomical information obtained by parsing a climber’s body area into its constituent anatomical parts. In ensuring that game events consider anatomical information, a climbing game can provide a more immersive experience for gamers.

Abstract
ABSTRACT Pelvic fractures correspond to 20 to 30 % of the fractures observed in dogs. Complete fractures, especially with bone axis deviation should be surgically treated. The mechanical study of surgical techniques is of utmost importance to assess the best way of treating these injuries. This study compared, biomechanically, the use of a dynamic compression plate (DCP) and screws (group 1) or screws and polymethylmethacrylate (PMMA) (group 2) to stabilize an iliac fracture using a static test. Sixteen canine synthetic hemi-pelvises (test specimens) with a transverse iliac osteotomy were used. After fixation with implants, a load was applied to the acetabulum until failure. Group 1 maximal compressive load was 133.9±18.60 N, displacement at yield 21.10±3.59mm and stiffness 125.22±12.25N/mm. Group 2 maximal compressive load was 183.50±27.38N, displacement at yield 16.66±5.42mm and stiffness 215.68±33.34N/mm. The stabilization with polymethylmethacrylate was stronger than dynamic compression plate since it resisted a greater load in all test specimens.

Abstract
Background Iatrogenic ureteral injuries arise as serious complication following obstetrics, gynecological, general, and urological surgery with incidence in the range of 0.5-10%. Retrograde placement of double-J ureteric stent is a possible treatment option if the injury is not recognized at the time of surgery. Purpose To assess technical success and long-term outcome associated with retrograde ureteric stent insertion for iatrogenic ureteric injury. Material and Methods Between 1999 and 2011, 26 patients with initially unrecognized iatrogenic ureteric injury underwent initial management with retrograde ureteric stenting. Full case-notes were available for review in 25 patients. Results The mean interval from injury to attempted stenting was 19.4 days. Successful retrograde ureteric stenting was achieved in 21/25 patients (81%). Retrograde stenting failed in four patients, and nephrostomy followed by alternative procedures were performed instead. At a median follow-up interval of 9.7 months, normal anatomy was demonstrated on 12/21 patients (57%) and a stricture was observed in 6/21 patients (28%) with three requiring surgical intervention. Conclusion Retrograde stenting is a safe and efficient initial management in patients with iatrogenic ureteric injuries.

Abstract
BACKGROUND AND OBJECTIVES Elevated blood lead levels have well-described detrimental effects to growth and development in children, yet screening rates remain low. We sought to determine if a reminder within the electronic health record (EHR) could change provider behavior and improve blood lead level (BLL) screening test ordering rates in an urban academic family medicine practice. METHODS Baseline BLL test ordering rates were calculated for children ages 9-72 months. An update adding reminders to screen was made to the electronic note template used during pediatric well and sick visits at the practice. Data from the 10-week periods both before and after the change was made were compared through a retrospective chart review. RESULTS A total of 210 children were seen during the pre-intervention period. Forty-eight percent (n=101) had already been screened. Of the 109 eligible for screening, 23 had tests ordered, and 18 of those had tests completed. Eighty-four children were eligible for screening in the post-intervention period. Forty-one of those children had tests ordered, and 15 had tests completed. Provider ordering rates increased from 21% of eligible patients to 49%. Test completion rates only increased from 17% to 18%. CONCLUSIONS An electronic note-based reminder system significantly improves provider ordering rates of BLL tests. Researchers are currently investigating how the use of point-of-care BLL sample collection can improve test completion rates and therefore increase the frequency of successful screening.

Abstract
AIM To assess the clinical utility of perfusion computed tomography (pCT) parameters in microwave ablation (MWA) of lung tumours. MATERIALS AND METHODS Patients were included who had primary or metastatic lung tumours and underwent pCT studies immediately pre- and post-MWA. Perfusion maps of the tumours were constructed using CT perfusion software (GE, Milwaukee, WI, USA). Regions of interest were drawn on sequential axial sections to extract the pCT parameters, blood volume (BV), average blood flow (BF), and mean transit time (MTT) from the entire tumour volume. Direct visualisation of perfusion maps were performed by two experienced readers blinded to outcome. Data were analysed using the Mann-Whitney test. RESULTS Thirty-one patients with 34 lung tumours had follow-up data at 12 months. The median tumour diameter was 19 mm (10-52 mm). Seven patients developed local tumour progression (LTP) at 12 months. There was no statistical difference between patients with LTP and complete treatment based on quantitative pCT parameters. Using radiologist visualisation of perfusion maps, there was moderate agreement between the two readers (kappa coefficient 0.53) with a combined 96% sensitivity, 62% specificity, 91% positive predictive value, and 80% negative predictive value. CONCLUSION Quantitative pCT parameters do not help differentiate between LTP and complete treatment, but subjective analysis of perfusion maps may be a useful assessment tool for identifying treatment adequacy potentially enabling identification of areas requiring further treatment at the time of the procedure.
