Abstract
BACKGROUND AND PURPOSE CSF-venous fistula can be diagnosed with multiple myelographic techniques; however, no prior work has characterized the time to contrast opacification and the duration of visualization. The purpose of our study was to evaluate the temporal characteristics of CSF-venous fistula on digital subtraction myelography. MATERIALS AND METHODS We reviewed the digital subtraction myelography images of 26 patients with CSF-venous fistulas. We evaluated how long the CSF-venous fistula took to opacify after contrast reached the spinal level of interest and how long it remained opacified. Patient demographics, CSF-venous fistula treatment, brain MR imaging findings, CSF-venous fistula spinal level, and CSF-venous fistula laterality were recorded. RESULTS Eight of the 26 CSF-venous fistulas were seen on both the upper- and lower-FOV digital subtraction myelography, for a total of 34 CSF-venous fistula views evaluated on digital subtraction myelography. The mean time to appearance was 9.1 seconds (range, 0-30 seconds). Twenty-two (84.6%) of the CSF-venous fistulas were on the right. The highest fistula level was C7, while the lowest was T13 (13 rib-bearing vertebral bodies). The most common CSF-venous fistula levels were T6 (4 patients) followed by T8, T10, and T11 (3 patients each). The mean age was 58.3 years (range, 31.7-87.6 years). Sixteen patients were women (61.5%). CONCLUSIONS This is the first study to report the temporal characteristics of CSF-venous fistulas using digital subtraction myelography. We found that on average, the CSF-venous fistula appeared 9.1 seconds (range, 0-30 seconds) after intrathecal contrast reached the spinal level.

Abstract
BACKGROUND Improvements in revascularisation, including pharmacological, catheter-based and surgical, have resulted in improved outcomes for patients with acute myocardial infarction (AMI), leading to decreased frequency of mechanical complications. Improvements in both techniques and technology have permitted select patients to be managed with a purely percutaneous, transcatheter strategy. Through systematic review, this study aims to synthesise the collective experience of percutaneous treatment of the mechanical complications of ischaemic heart disease. METHODS The search strategy queried the electronic databases PubMed, Embase and the Cochrane Central Register of Controlled Trials, from 1 January 2000 to 31 December 2020. Studies highlighting the outcomes of patients receiving percutaneous treatment of post-myocardial infarction papillary muscle rupture (PMR), ventricular septal defect (VSD), left ventricular free wall rupture (FWR) and pseudoaneurysm (PA) were included. A qualitative review of studies was conducted for PMR, FWR and PA. A quantitative analysis was conducted for VSD. RESULTS Fifteen studies were included in the qualitative synthesis of the percutaneous management of PMR, 4 were included in the qualitative analysis of the percutaneous management of left ventricular FWR, 7 studies defined the outcomes of the percutaneous management of PA and 25 were included in the quantitative meta-analysis of the primary percutaneous management of post-MI VSD. For VSD, there were 43 failed procedures in 314 patients. The proportion of failed procedures was 15.9% and there were 174 deaths in 428 patients. 37.5% of patients experienced early mortality. CONCLUSIONS Although surgical techniques remain the gold standard, we have shown that percutaneous management may be a viable option in certain cases.

Abstract
Gamma-ray bursts (GRBs), which are bright flashes of gamma rays from extragalactic sources followed by fading afterglow emission, are associated with stellar core collapse events. We report the detection of very-high-energy (VHE) gamma rays from the afterglow of GRB 190829A, between 4 and 56 hours after the trigger, using the High Energy Stereoscopic System (H.E.S.S.). The low luminosity and redshift of GRB 190829A reduce both internal and external absorption, allowing determination of its intrinsic energy spectrum. Between energies of 0.18 and 3.3 tera-electron volts, this spectrum is described by a power law with photon index of 2.07 ± 0.09, similar to the x-ray spectrum. The x-ray and VHE gamma-ray light curves also show similar decay profiles. These similar characteristics in the x-ray and gamma-ray bands challenge GRB afterglow emission scenarios.

Abstract
Desmoplastic infantile tumors are rare supratentorial brain tumors that occur in pediatric patients. Desmoplastic infantile tumors are made up of 2 subtypes: desmoplastic infantile gangliogliomas and desmoplastic infantile astrocytomas. Desmoplastic infantile tumors are often identifiable on imaging on the basis of multiple characteristics. Nevertheless, pathologic analysis is required to confirm the diagnosis, particularly when the imaging features are atypical. Here, the radiology findings, surgical approach and subsequent management, and pathology of a desmoplastic infantile ganglioglioma are described.

Bioelectrical impedance analysis (BIA)-derived phase angle (PA) is a practical aid to nutritional assessment in hospital in-patients. Clin Nutr 2018; 38:1700-1706.

Abstract
BACKGROUND Nutritional status can be difficult to assess. Bioelectrical impedance analysis (BIA)-derived phase angle (PA), and the plasma markers citrulline and transthyretin (pre-albumin) have the potential to assist, but the protocol of fasting and resting for BIA renders the investigation impractical for routine use, especially so in populations at high risk of malnutrition. AIMS 1 To clarify whether starving and resting are necessary for reliable measurement of PA. 2 To identify whether PA, citrulline and transthyretin correlate with nutritional status. METHODS Eighty consenting adult in-patients were recruited. Nutritional status was determined by subjective global assessment (SGA) used as gold standard. The Malnutrition Universal Screening Tool (MUST) was used and anthropometric measurements were performed. Serum was analysed for citrulline and transthyretin. PA was measured using Bodystat 4000. The PA was considered to define malnutrition when lower than reference ranges for sex and age, and severe malnutrition if more than 2 integers below the lower limit. Anthropometric measurements were categorised according to WHO reference centiles. Ordinal logistic regression estimated the strength of association of PA, citrulline and transthyretin with SGA. PA values in the different metabolic states were compared using paired t tests. RESULTS All 80 subjects completed the BIA and the nutritional assessments in the 3 different states; 14 declined to provide blood samples for the biochemical assays. Malnutrition was identified in 32 cases, severe malnutrition in 14 cases, the remaining 34 cases were deemed not to be malnourished. PA was strongly inversely associated with SGA (Odds Ratio [OR] per unit increase = 0.21, CI 0.12-0.37, p < 0.001). PA was not influenced by exercise (p = 0.134) or food intake (p = 0.184). Transthyretin was inversely associated with malnourished/severely malnourished states (OR = 0.98, 95% CI 0.97-0.99, p = 0.001), but had poorer predictive values than PA. There was no significant association between citrulline concentration and SGA (OR = 1.01, 95% CI 0.99-1.04, p = 0.348). CONCLUSIONS The BIA-derived PA reliably identifies malnutrition. It is strongly associated with SGA but requires less skill and experience, and out-performs circulating transthyretin, rendering it a promising and less operator-dependent tool for assessing nutritional status in hospital patients. Our novel demonstration that fasting and bed-rest are unnecessary consolidates that position.

Wzx flippases exhibiting complex O-unit preferences require a new model for Wzx-substrate interactions. Microbiologyopen 2018; 8:e00655.

Abstract
The Wzx flippase is a critical component of the O‐antigen biosynthesis pathway, being responsible for the translocation of oligosaccharide O units across the inner membrane in Gram‐negative bacteria. Recent studies have shown that Wzx has a strong preference for its cognate O unit, but the types of O‐unit structural variance that a given Wzx can accommodate are poorly understood. In this study, we identified two Yersinia pseudotuberculosis Wzx that can distinguish between different terminal dideoxyhexose sugars on a common O‐unit main‐chain, despite both being able to translocate several other structurally‐divergent O units. We also identified other Y. pseudotuberculosis Wzx that can translocate a structurally divergent foreign O unit with high efficiency, and thus exhibit an apparently relaxed substrate preference. It now appears that Wzx substrate preference is more complex than previously suggested, and that not all O‐unit residues are equally important determinants of translocation efficiency. We propose a new “Structure‐Specific Triggering” model in which Wzx translocation proceeds at a low level for a wide variety of substrates, with high‐frequency translocation only being triggered by Wzx interacting with one or more preferred O‐unit structural elements found on its cognate O unit(s).

Abstract
INTRODUCTION While diagnostic algorithm using PF4-heparin enzyme-linked immunosorbent assay (ELISA) optical density (OD), and heparin neutralization assay (HNA), or 4T score have been proposed to replace serotonin-release assay (SRA) for heparin-induced thrombocytopenia (HIT), their performance against SRA is unclear. In this study, we proposed and validated the performance of a new algorithm combining PF4-heparin ELISA optical density (OD), HNA and 4T score against SRA for HIT diagnosis. METHODS Heparin neutralization assays were performed on specimens submitted for HIT testing with positive PF4-heparin ELISA from December 2015 to September 2017, which were separated into a "training" and a "validation" data set. 4T scores were calculated for ELISA positive cases. RESULTS A total of 123 consecutive unique patient samples had positive PF4-heparin ELISA with also HNA data, SRA data, and 4T scores available. Compared to SRA, a "laboratory criteria" (ELISA OD ≥ 1.4 and HNA ≥ 70%) had a sensitivity of 88% (14/16) and specificity of 91% (42/46), and a "combined criteria" (4T score = 8, or 4T score = 6 or 7 and ELISA OD ≥ 1.0, or 4T score = 4 or 5 and ELISA OD ≥ 2.0) had a sensitivity of 75% (12/16) and specificity of 98% (45/46) in the training data set. Laboratory and combined criteria had 90% (56/62) concordance rate. Importantly, for these concordant cases, the diagnostic specificity is 100% (46/46). Based on the data, a novel diagnostic algorithm combining these 2 criteria was proposed and validated prospectively. CONCLUSION A novel algorithm has high diagnostic accuracy and potentially could eliminate the need for SRA testing in at least 90% patients with suspected HIT.

Abstract
Serological surveillance testing for bovine brucellosis, Enzootic Bovine Leukosis, and Warble fly reaches approximately 1.7 million tests every year in the UK. An automated system was developed to improve the quality of data handling for all three surveys. The objectives were to make improvements in efficiency, sample tracking, and test reporting and to develop an epidemiological database. The developed system of bar-coded samples and test plates processed on automated equipment capable of scanning barcodes and transferring information across a computer network met the data objectives. Consolidating and automating the highly repetitive liquid-handling steps met the cost objectives. To reduce the impact of temporary bottlenecks in the system, a philosophy of ‘islands of automation’ was adopted to maximize the throughput. The creation of this system was driven largely by the need to have in place an effective emergency response capability to handle the serological needs of an outbreak of an acute and highly infectious veterinary disease such as Foot and Mouth Disease (FMD) in the UK.

Abstract
Abstract
Background: The combination of the anthracycline, doxorubicin with cyclophosphamide (AC) is a widely used chemotherapy regimen in early stage breast cancer. Studies have shown that dose dense chemotherapy (incorporating AC) improved both disease-free survival and overall survival compared to once every 3 week treatment with daily subcutaneous G-CSF support. An important advance in the use of dose dense chemotherapy regimens was the development of pegylated forms of G-CSF, which offered the convenience of a single subcutaneous injection, rather than multiple daily injections. Lipegfilgrastim is a pegylated long-acting covalent conjugate of filgrastim (G-CSF). In a pivotal randomised phase III study in breast cancer lipegfilgrastim was shown to be non-inferior to pegfilgrastim. Although lipegfilgrastim is licensed in Europe and can facilitate every 2 week (dose dense) scheduling of chemotherapy there are a lack of prospective data about its efficacy in this setting. In this prospective, non-interventional, study we are investigating the incidence of treatment-related neutropaenia following four cycles of dose dense AC with lipegfilgrastim support.
Methods: The primary end point of this prospective, single arm study is to determine the incidence of treatment-related neutropaenia, defined as an absolute neutrophil count (ANC) of <1.0 x 109/L, following four cycles of dose dense AC with lipegfilgrastim support. The secondary end points are to (1) determine the incidence of febrile neutropaenia, defined as temperature > 38°C and ANC <1.0 x 109/L, during 4 cycles of dose dense AC with lipegfilgrastim and (2) examine the incidence of treatment-related neutropaenia during subsequent intravenous chemotherapy post completion of AC. Eligibility criteria include, patients with stage I-III breast cancer, planned treatment with dose dense AC in the adjuvant or neoadjuvant setting, age ≥ 18 years, Eastern Cooperative Oncology Group (ECOG) Performance Status 0-1 and adequate bone marrow function. Patients with prior exposure to chemotherapy and/or G-CSF, who are pregnant, have a cardiac or other concurrent illness, which at the investigator's discretion contraindicates the use of AC will be excluded. We will enrol 40 consecutive patients who are planned to undergo dose dense AC. Based on previous clinical trials, we expect that the incidence of treatment-related neutropaenia will be <12%. However, it is likely that the current study will more closely resemble real-world practice and a higher incidence of treatment-related neutropaenia may be observed. This study has been approved by the Instituational Review Board and 9 patients have been consented to date. (registered with clinicaltrials.gov).

Abstract
OBJECTIVE The aim of this study was to assess conventional two-dimensional (2D) ultrasound enhanced with a three-dimensional (3D) ultrasound technique, the 'reverse-face' view (3D-RF) in prenatal evaluation of the involvement of the lips, alveolar ridge and secondary palate in suspected isolated orofacial clefting. METHODS One hundred and twenty-four cases of suspected orofacial clefting diagnosed by a routine 2D ultrasound scan were referred for specialist ultrasound at 20-34 weeks' gestation for a detailed assessment of the lips and palate using both 2D and 3D ultrasound. For the 3D examination the lips and alveolar ridges were examined both in profile and in the frontal plane. The palate was then assessed in the reverse coronal view by rotating the face through 180° on the vertical axis to produce the 3D-RF view. Antenatal diagnoses were compared with postnatal findings. Left and right lip and alveolar ridge defects were counted separately according to the Kernohan 'striped Y' classification. RESULTS Of 124 patients, 110 had isolated facial clefts and were available for follow-up; in 10, 3D-RF views were not successfully obtained, leaving 100 cases for assessment. The sensitivity of the 2D enhanced with 3D-RF technique for the diagnosis of cleft of the lip was 116/122 (95%), false-positive rate (FPR) 7.7%; for alveolar ridge was 87/103 (84.5%), FPR 7.2%; and for hard palate was 61/68 (89.7%), FPR 15.6%. CONCLUSION The data reported represent the largest series of orofacial abnormalities diagnosed by 2D ultrasound and enhanced with 3D imaging to refine the detection of clefts of the hard palate. The technique is feasible in 90% of patients in whom almost 90% have a correct classification of clefts of the lip, alveolar ridge and palate.

Abstract
Abstract
BackgroundThe early detection of cardiotoxicity and congestive heart failure (CHF) from anthracyclines and anti-HER2 agents is currently limited to measuring changes in left ventricular ejection fraction (LVEF) at arbitrary time points. This approach has limited sensitivity and specificity and has led to the investigation of putative biomarkers such as cardiac Troponin I (TnI), a highly specific marker of myocardial damage and C-reactive protein (CRP), a sensitive inflammatory marker. In a pre-planned analysis we investigated these as biomarkers of cardiotoxicity within a prospective study testing the feasibility of ddAC- followed by weekly P with T and L.Materials and MethodsPatients (pts) with HER2+ EBC enrolled at MSKCC and DF/HCC and received ddAC (A 60mg/m2 + C 600mg/m2) x 4 → weekly P (80mg/m2) x 12 + T + L (1000mg/day). T+L continued for a total of 1yr. At baseline pts had LVEF ≥50%. Pts with unstable angina, CHF, recent MI, uncontrolled arrhythmia, grade 3 QT prolongation were excluded. LVEF was assessed by MUGA scan at mths 0, 2, 6, 9 and 18. TnI and CRP were measured every 2 wks right before treatment (Rx) during ddAC-PTL, then at mths 6, 9 and 18. TnI was categorized as “undetectable” (< 0.06 ng/ml; MSKCC, <0.04 ng/ml; DF/HCC), “minimally elevated” (<0.31 ng/ml) and “elevated” (>0.31ng/ml). Elevated CRP was defined as (>0.8mg/dl; MSKCC, >0.3mg/dl; DF/HCC). Investigators were blinded to these results until pts completed 18mth follow-up (F/U).ResultsFrom Apr 07- Apr 08, 95 pts were enrolled; 39/95 (41%) withdrew due to PTL toxicities (incl. 3 with asymptomatic LVEF (aLVEF) declines and 3 with CHF). Final biomarker results were available in 84 pts (88%) and 11 pts (12%) continue on study. During Rx, minimal elevations in TnI occurred in 55 pts (65%). One pt had ↑TnI above normal range with AC#4; MUGA 1 wk later was unchanged (LVEF 75%), but she died from sepsis during subsequent Rx without evidence of CHF. Elevations in TnI occurred only during chemoRx and no pt had a ↑TnI during TL or at 18mth F/U. Of 55pts with elevated TnI, 25 (45%) had aLVEF declines (3 ↓ ≥16%, 10 ↓ 10-15%, 12 ↓ 5<10%). Of 29 pts with undetectable TnI, 7 (24%) had aLVEF declines (1 ↓ ≥16%, 4 ↓ 10-15%, 2↓ 5<10%). Elevations in CRP occurred in 61/84 (73%) pts during chemoRx but only in 22 (26%) during TL or at 18mth F/U. Three pts discontinued Rx for aLVEF ↓ at mths 4, 5 and 7 respectively; 2 (66%) had rises in CRP and 2 had minimal elevation in TnI. Three pts developed CHF at mths 3, 6, and 12 respectively, all had rises in CRP; 1 pt had a single ↑TnI of 0.08 ng/ml during chemoRx, and 2pts had no ↑TnIs.ConclusionsIn pts receiving ddAC-PTL fluctuations in TnI and CRP are common but do not persist after chemoRx (during TL). These biomarkers do not appear to predict for CHF. One possibility is that the timing of the drawing of these biomarkers (immediately preceding the specified treatment cycle and after Rx completion) may have been suboptimal. We plan to assess for potential biomarkers by assessing both immediately preceding and following therapy in a planned trial. Updated results will be presented.

Abstract
Abstract
Background: Adjuvant therapy for breast cancer (BCA) may be associated with an increased risk for osteoporosis. This prospective, observational study evaluates BMD changes in postmenopausal women undergoing adjuvant chemotherapy (CTX) for early stage BCA, in the absence of endocrine therapy.Methods: Women who have been postmenopausal for at least 5 years, and who were recently diagnosed with Stage 0-III BCA were eligible to undergo serial BMD if adjuvant endocrine therapy was not recommended. Study BMDs were performed at baseline, 1 and 2 years. All patients (pts) were counseled on calcium, vitamin D and weight bearing exercise. This study was designed to assess serial changes in BMD in the individual and to compare changes in those treated with CTX to those who received no systemic therapy (observation). The study was closed prior to reaching target sample size due to slow accrual.Results: Sixteen pts enrolled. Eleven pts received CTX with a dose dense anthracycline and taxane containing regimen and 5 pts received no systemic adjuvant therapy. Twelve pts, median age 63 (range 52-80), have completed the 1 year assessment and are reported here. Two pts treated with CTX and 1 pt on observation were on bisphosphonates at study entry. Baseline BMD mean in gm/cm2 at the lumbar spine (LS) was 1.112 (range 0.807-1.389) and total hip (TH) was 0.989 (range 0.760-1.213). At 1 year, mean BMD at LS was 1.078 (range 0.767-1.347) and TH was 0.956 (range 0.753-1.210). For all 12 pts at 1 year, the individual BMD changes in LS & TH BMD ranged from 10% loss to 2% gain, with 8 of the 9 CTX treated pts losing 1-10% of BMD and the 3 pts on observation staying within 2% of baseline. The mean dosage of dexamethasone used during CTX by the 9 CTX pts was 230 mg (range 156-288mg). The 3 observation pts had no exposure to steroids during the parallel time period.Conclusions: This prospective, observational study supports the hypothesis that adjuvant CTX, and/or its supportive medications, may be associated with acute changes in BMD in postmenopausal women. Patient follow up continues.Funded by Susan G. Komen for the Cure POP0402593

Abstract #5007
Background: 
 The accurate detection of osseous metastases frequently has significant prognostic and therapeutic implications at metastatic breast cancer (MBC) diagnosis. However, the ideal paradigm for accurate detection of osseous metastases has not yet been determined. In this retrospective, single-institution study, we compare the diagnostic performance of integrated positron emission tomography/computed tomography (PET/CT) versus bone scintigraphy (BS) for women undergoing extent-of-disease (EOD) evaluation for suspected MBC.
 Methods:
 Women undergoing EOD evaluation for suspected MBC with integrated PET/CT and bone scintigraphy (BS) between January 1, 2005 and Dec 31, 2007 were identified through institutional databases. Patients with PET/CT and BS imaging completed within 30-days of each other were included. Women with a prior history of MBC or an active second malignancy were excluded. Electronic medical record (EMR) reports were reviewed and classified as positive, negative or equivocal for detecting osseous metastases. All EMR reports deemed potentially equivocal were reviewed by 2 investigators and consensus reached regarding the final classification. Bone biopsy data, where available, was also recorded.
 Results:
 The median age of the 62 eligible women was 54y (33-90y). Overall, PET/CT and BS demonstrated a high degree of concordance. Of the 41 concordant studies, 13 (21%) and 28 (45%) were reported as positive and negative for osseous metastases, respectively. No studies were classified as equivocal by both modalities. Ten positive PET/CT studies were negative by BS, but no PET/CT-negative studies were positive by BS. Of the 10 patients with PET/CT-positive, BS-negative studies, 4 had subsequent bone biopsies, all of which confirmed osseous metastases.
 
 Conclusions:
 This study supports the diagnostic performance of integrated PET/CT in detecting osseous metastases when EOD evaluation for suspected MBC is considered. Whether PET/CT may supplant BS entirely in this setting has not yet been determined.

Abstract
Obesity is the commonest nutritional disorder of companion animals. In rodents and humans, white adipose tissue is a major endocrine and secretory organ, releasing adipokines linked to inflammation. In this study, we examined whether nerve growth factor (NGF), a target-derived neurotrophin central to the development/maintenance of sympathetic innervation and an inflammatory response protein, is synthesized and secreted by canine adipocytes. NGF mRNA was detected in each of the major fat depots (the subcutaneous, inguinal, gonadal, perirenal, and falciform ligaments) of dogs at similar levels. Canine adipocytes, differentiated from preadipocytes (inguinal depot) in primary culture, expressed the NGF gene and secreted NGF both pre- and post-differentiation. Treatment of the differentiated adipocytes with LPS resulted in a dramatic increase in NGF mRNA levels (20-fold at 24 h) and in NGF protein in the medium (60-fold at 24 h). The proinflammatory cytokine TNFalpha also led to a substantial increase in NGF mRNA levels (11-fold) and protein secretion (16-fold), while IL-6 had little effect. In contrast, dexamethasone decreased both NGF mRNA levels (80%) and protein release (60%). The PPARgamma agonist rosiglitazone also reduced NGF secretion. These results demonstrate that canine white adipocytes synthesize and secrete NGF, the powerful upregulation by LPS and TNFalpha indicating that the neurotrophin is strongly linked to the inflammatory response in canine WAT. Canine adipocytes appear highly sensitive to inflammatory stimuli.

Abstract
UNLABELLED A study was performed to characterize the concentration of dozens of volatile organic compounds (VOCs) at 10 locations within a single large building and track these concentrations over a 2-year period. The study was performed at a shopping center (strip mall) in New Jersey. A total of 130 indoor air samples were collected from 10 retail stores within the shopping center and analyzed for 60 VOCs by US EPA Method TO-15. Indoor concentrations of up to 55,100 microg/m(3) were measured for individual VOCs. The indoor/outdoor ratio (I/O) was as high as 1500 for acetone and exceeded 100 at times for various compounds, indicating that significant indoor air sources were present. A large degree of spatial variability was observed between stores within the building, with concentrations varying by three to four orders of magnitude for some compounds. The spatial variability was dependent on the proximity of the sampling locations to the indoor sources. A large degree of temporal variability also was observed for compounds emitted from indoor sources, but the temporal variability generally did not exceed two standard deviations (sigma). For compounds not emitted from indoor sources at significant rates, both the spatial and temporal variability tended to range within an order of magnitude at each location. PRACTICAL IMPLICATIONS Many cross-sectional studies have been published where the levels of volatile organic compounds (VOCs) were measured in indoor air at one or two locations for houses or offices. This study provides longitudinal data for a commercial retail building and also addresses spatial variability within the building. The data suggest that spatial and temporal variability are important considerations for compounds emitted from indoor sources. Elevated concentrations were found in retail spaces with no apparent emission sources due to their proximity to other retail spaces with emission sources.
