Abstract
Abstract
Background
The COVID-19 crisis poses challenges to healthcare systems and their employees. Medical staff are at the front of the battle against COVID-19. They must cope with a crisis accompanied by personal health and occupational ramifications and ongoing job stressors, which may lead to adverse mental health symptoms and may affect the quality of medical care provided to patients. This study evaluated health workers' perceptions and concerns about the COVID-19 crisis and its management in an Israeli hospital.
Methods
At the end of the pandemic's first wave in Israel, 547 healthcare workers responded to an online survey, which inquired about COVID-19 concerns at the individual and family level, perceptions at the national and organizational level, perceptions of the way the crisis was managed, self-assessment of coping with the crisis and burnout, and demographics.
Results
Findings showed that healthcare workers expressed deep concerns for family members and apprehension at a national level. Respondents noted that they were coping well with the crisis while expressing negative perceptions of how the crisis was managed. The regression model showed that concerns for family members, perceptions at the system level, working directly with COVID-19 patients, and having negative perceptions towards the crisis management at the national level, were associated with burnout.
Conclusions
The findings of this study deepen our understanding of issues that require systemic attention to strengthen mental resilience among hospital staff. Several actions are recommended to improve healthcare systems' ability to continue fighting the virus and confront future health crises:
Further examination and monitoring of healthcare workers' concerns and job stressors. Providing psychosocial support plans for frontline workers to ensure their safety and health and prevent burnout. Strengthening supportive organizational culture.
Key messages
Healthcare workers express deep concerns and perceptions associated with burnout. Health services management needs a good understanding of workers' concerns and develop strategies to address them.

Abstract
BACKGROUND AND PURPOSE Glioblastoma-associated macrophages are a major constituent of the immune response to therapy and are known to engulf the iron-based MR imaging contrast agent, ferumoxytol. Current ferumoxytol MR imaging techniques for localizing macrophages are confounded by contaminating intravascular signal. The aim of this study was to assess the utility of a newly developed MR imaging technique, segregation and extravascular localization of ferumoxytol imaging, for differentiating extravascular-from-intravascular ferumoxytol contrast signal at a delayed 24-hour imaging time point. MATERIALS AND METHODS Twenty-three patients with suspected post-chemoradiotherapy glioblastoma progression underwent ferumoxytol-enhanced SWI. Segregation and extravascular localization of ferumoxytol imaging maps were generated as the voxelwise difference of the delayed (24 hours) from the early (immediately after administration) time point SWI maps. Continuous segregation and extravascular localization of ferumoxytol imaging map values were separated into positive and negative components. Image-guided biologic correlation was performed. RESULTS Negative segregation and extravascular localization of ferumoxytol imaging values correlated with early and delayed time point SWI values, demonstrating that intravascular signal detected in the early time point persists into the delayed time point. Positive segregation and extravascular localization of ferumoxytol imaging values correlated only with delayed time point SWI values, suggesting successful detection of the newly developed extravascular signal. CONCLUSIONS Segregation and extravascular localization of ferumoxytol MR imaging improves on current techniques by eliminating intrinsic tissue and intravascular ferumoxytol signal and may inform glioblastoma outcomes by serving as a more specific metric of macrophage content compared with uncorrected T1 and SWI techniques.

Abstract
Background:Chronic kidney disease/end stage renal disease (CKD/ESRD) from lupus nephritis (LN) is a major cause of morbidity and mortality. Advanced tubulointerstitial disease (TID) in LN is a better predicor of renal outcome than glomerular lesions. The current NIH classification is heavily weighted towards glomerular lesions and only provides a semiqualitative assessment of TID. In contrast, Banff classification of renal allograft pathology provides 6 reproducible scores for TID (inflammation, fibrosis, atrophy). Banff scoring may better predict CKD/ESRD in LN than NIH scoresObjectives:We compared Banff grading vs. NIH scoring as predictors of CKD progression at 5 years, defined as a decline in estimated glomerular filtration rate (eGFR) ≥30%, a strong risk factor for ESRD and mortalityMethods:We included patients with LN class III, IV, V on the index biopsy Jan 2005 and Dec 2018. H&E/PAS stained slides were reviewed and scored by an experienced pathologist. Six TID Banff scores (0/1 vs. 2/3), NIH activity/chronicity (AI/CI) and NIH interstitial fibrosis/tubular atrophy (IF/TA), tubulointerstitial inflammation (TII) scores (none/mild vs. moderate/severe) were evaluated as predictors of CKD progression using survival analysesResults:Of the 125 patients, 46 had CKD progression and 20 subsequently developed ESRD. There were no differences between progressors and non-progressors in terms of baseline demographic, clinical data, LN class (Tab 1). Banff ti score (total inflammation) was associated with CKD progression in bivariate and time-dependent analyses. However, NIH TII score and corresponding Banff i score were not predictive (Tab 2, Fig 1). Overall NIH AI and CI were not predictive of CKD progression. Moderate/severe NIH IF/TA was associated with CKD progression as was Banff ci (interstitial fibrosis) score (Tab 2, Fig 2). Banff score for atrophy was not predictive. In a subset of 92 patients with baseline eGFR≥60ml/min/1.73m2only Banff ti score (but not i score or NIH TII, IF/TA) was predictive of CKD progression (Fig 1)Table 1.Baseline data in patients with/without CKD progressionProgressors1n=46Non-progressorsn=79pn (%) or median (IQR)Female36 (78)69 (87)0.18Age (years)26 (20-41)29 (21-43)0.53<18 years7 (15)13 (16)0.86Race0.82 White4 (9)4 (5) Black18 (39)35 (44) Asian1 (2)1 (1) Unknown23 (50)39 (50)Diabetes5 (11)3 (4)0.12Hypertension33 (72)55 (70)0.8eGFR ml/min/1.73m296.1 (56.6-117.8)88.9 (47-117)0.51C3 mg/dL71 (52-88)67.5 (43-94)0.58C4 mg/dL12.65 (9-23)12 (7-20)0.48Anti-ds DNA titer IU108.7(36.6-194.9)151.3(39.2-200)0.57Total SLEDAI11 (8-16)12 (8-16)0.47Renal SLEDAI8 (4-12)8 (4-12)0.9LNProliferative GN2: III, IV18 (39)30 (38)0.15Nonproliferative GN: V9 (20)27 (34)Mixed GN: V and III/IV19 (41)22 (28)1Progressors: LN patients with eGFR decline ≥30% within 5 years.2GN: glomerulonephritisTable 2.NIH and Banff scores with/without progressorsProgressorsn=46Non-progressorsn=79pn (%) or median (IQR)NIHOverall AI1 (0-4)1 (0-3)0.61AI ≥ 111 (2)3 (3.8)0.62Overall CI3 (0-5)2 (0-3)0.33CI ≥ 324 (52)28 (35.4)0.07Moderate/severe TII7 (15.2)4 (5)0.05Moderate/severe IF/TA16 (35)15 (19)0.049BanffTubulitis: t00Interstitial inflammation: i 2/33 (6.5)5 (6.3)0.9Total inflammation: ti 2/316 (34.8)12 (15.2)0.01Tubular atrophy: ct 2/316 (34.8)16 (20.3)0.07Interstitial fibrosis: ci 2/317 (37)15 (19)0.03Inflammation in area of interstitial fibrosis and/or tubular atrophy: i-IFTA 2/3n=26*18 (69)n=51*25 (49)0.09* Biopsy number is smaller due to inability to apply score to biopsies without areas of fibrosis/tubular atrophyConclusion:Banff inflammation scores may be superior predictors of CKD/ESRD progression at 5 years, compared to the currently used NIH classification.

Abstract
Abstract
Introduction
Recent work has highlighted prevalent obstructive sleep apnea (OSA) after traumatic brain injury (TBI) when patients are vulnerable to disruption of neural repair. The recently completed clinical trial comparing screening and diagnostic tools for OSA during inpatient rehabilitation provided the opportunity to conduct economic modeling of phased approaches using actual trial findings to address one perspective (the payor) on the value of phased testing.
Methods
A cost-effectiveness analysis of four phased approaches to OSA diagnosis including initial utilization of portable sleep monitoring [HSAT] regardless of pre-test probability, determination of pre-test probability using two prediction models [STOPBANG, MAPI], and initial assessment using Level 1 polysomnography was conducted. The analyses were modeled assuming all participants were considered high risk thus a negative screen or portable diagnostic test would result in a participant being referred for Level 1 polysomnography. The cost aversion used in analyses were derived from a recent white paper on the economic modeling of untreated OSA. Trial data from 214 participants were used in analyses (mean age 44 [SD 18], 82% male, 75% white, with primarily motor-vehicle related injury [44%] and falls [33%] with a sample mean emergency department Glasgow Coma Scale of 8 (SD 5).
Results
At AHI ≥15 (33.6%), the prediction models (STOPBANG [-$5,291], MAPI [-$5,262]) resulted in greater cost savings and effectiveness relative to the HSAT approach (-$5,210) and initial use of Level 1 PSG (-$5,011). Sensitivity analyses at AHI ≥5 (70.1%) revealed the initial use of HSAT (-$6,322.85) relative to the prediction models (MAPI [-$6,249.71], STOPBANG [-$6,237) and initial assessment with Level 1 PSG (-$5,977) resulted in greater savings and cost effectiveness.
Conclusion
The high rates of sleep apnea after TBI highlight the importance of accurate diagnosis and treatment of this comorbid disorder. However, financial and practical barriers exist to obtaining an earlier diagnosis during inpatient rehabilitation hospitalization. Diagnostic cost savings are demonstrated across all phased approaches and OSA severity levels with the most cost-effective approach varying by incidence of OSA.

Abstract
Abstract
Introduction
A recent meta-analytic report highlighted that obstructive sleep apnea was 12 times more prevalent in TBI (mixed severity) than in community-based samples. Recent studies highlight prevalent obstructive sleep apnea during acute inpatient rehabilitation which is a time of critical neural repair. Acute sleep disturbances are associated with therapy cooperation due to effects on daytime sleepiness and are associated with key rehabilitation outcomes. Given the high rates of OSA and risk for negative morbidity, this analysis sought to examine the feasibility of administering polysomnography (PSG) with EEG to diagnose sleep apnea during inpatient rehabilitation in persons with moderate to severe TBI.
Methods
This is a secondary analysis from a prospective diagnostic comparative effectiveness clinical trial (NCT03033901) that took place at six NIDILRR and one VA TBI Model System Centers. Participants were included if they met the TBI Model System case definition and slept at least 2 hours per night prior to PSG. PSG was conducted following AASM procedures in the participant’s hospital bed on the inpatient rehabilitation unit. Studies were scored by RPSGT staff and interpreted by a board certified sleep medicine physician at a centralized sleep scoring center in Tampa, FL.
Results
Of 896 potential TBI participants, 449 met initial eligibility and 345 consented for further screening; a final sample of 263 (76%) completed PSG during hospitalization. Primary reasons for not completing PSG included early discharge or medical instability (n=59) and last-minute withdrawal of consent for PSG (n=23). Of the 263 participants who completed PSG, 3 were excluded from analysis due to technical issues and 12 were excluded as the total sleep time (TST) was less than 120 minutes. Of the 248, 85.5% of the PSGs were rated as interpretable/scoreable by RPSGT and sleep physicians.
Conclusion
For a majority of participants, polysomnography is feasible during inpatient rehabilitation. Participants with shorter lengths of stay, medical instability, prolonged agitation may require polysomnography follow-up after discharge.

Abstract
Abstract
Introduction
Recent studies highlight prevalent obstructive sleep apnea after moderate to severe TBI during a time of critical neural repair. The purpose of this study is to determine the diagnostic sensitivity, specificity and comparative effectiveness of traditional sleep apnea screening tools in TBI neurorehabilitation admissions.
Methods
This is a prospective diagnostic comparative effectiveness trial of sleep apnea screening tools (STOPBANG, Berlin, MAPI [Multi-Apnea Prediction Index]) relative Level 1 polysomnography at six TBI Model System Inpatient Rehabilitation Centers. Between 05/2017 and 02/2019, 449 of 896 screened were eligible for the trial with 345 consented (77% consented). Additional screening left 263 eligible for and completing polysomnography with final analyses completed on 248. The primary outcome was the Area Under the Curve (AUC) of screening tools relative to total apnea hypopnea index ≥15 (AHI, moderate to severe apnea) measured at a median of 47 days post-TBI (IQR 29-47).
Results
Participants were primarily young to middle age (AGE IQR 28,40,59), male (81%), white (74%), and had primarily severe TBI (IQR GCS 3,6,14). A subset (26%) had a history of military service. Results revealed that the Berlin high risk score (ROC-AUC=0.63) was inferior to the MAPI (ROC-AUC = 0.7802) (p=.0211, CI: 0.0181, 0.2233) and STOPBANG (ROCAUC = 0.7852) (p=.0006, CI: 0.0629, 0.2302); both of which had comparable AUC (p=.7245, CI: -0.0472, 0.0678). Findings were similar for AHI≥30 (severe apnea); however, no differences across scales was observed at AHI>5. The pattern was similar across TBI severity subgroups except for delirium or post-traumatic amnesia status wherein the MAPI outperformed the Berlin and STOPBANG. Youden’s Index to determine risk yielded lower sensitivities but higher specificities relative to non-TBI samples.
Conclusion
This study is the first to provide clinicians with data to support a choice for which sleep apnea screening tools are more effective during inpatient rehabilitation for moderate to severe TBI (STOPBANG, MAPI vs Berlin) to help reduce comorbidity and possibly improve neurologic outcome.

Abstract
Abstract
Introduction
Normal respiratory function is crucial for adequate sleep. Sleep Related Breathing Disorders, namely Obstructive Sleep Apnea (OSA) are frequent conditions among a large spectrum of obstructive events in the upper airway which are often linked to significant sleep related oxyhemoglobin dessaturation levels compared to those observed in baseline PSG-oximetry recorded. On the other hand, low baseline oxygen saturation (LBOS) is commonly linked to symptomatic cardiorespiratory disturbances which may adversely impact respiratory outcomes either awake or during sleep. Therefore it is relevant to be aware of the baseline ventilatory status in order to optimize the therapeutic care.
Report of Case
We present an unusual case of a patient with moderate OSA which was successfully controlled with a Mandibular Advancement Oral Appliance (OAm). Despite the control with the OAm, the patient still maintained a nocturnal pattern of hypoventilation/hypoxia. The 53 yo female patient with normal weight/height ratio (BMI=25,2) complaining of non restorative sleep, tiredness, impaired memory, excessive diurnal sleepiness (Epworth Sleepiness Scale - ESS=10 and bruxism with a PSG diagnosis of moderate OSA (BaselineO2Sat=94%; IAH=17,4 ev/h; ODI=32,9 ev/h; T90=34,7% of TST) was referred for treatment with a OAm. A PM Type 1 positioner was inserted and titrated until 12 mm of advancement (80% of maximal measured protrusion). Within 6 months follow up and after clinical titration, there was a clear symptomatic and objective improvement with resolution of all major complaints including sleepiness (ESS=5). Titration PSG showed a normalization in all parameters (IAH=1,4 ev/h;ODI=4 ev/h;T90=0,1% of TST). Baseline O2 Sat however remained low (93%) in the titration PSG even though no symptoms or signs of a disorder existed even after discounting for Ph related metabolic changes (normal levels of HCO3)
Conclusion
This is an interesting case of an unusual patient who presented with a LBOS level in the diagnostic PSG. Despite the therapeutic success of the OAm in controlling the sleep related respiratory condition, measured by all otherwise normalized PSG based sleep and respiratory parameters, maintained a LBOS in the titration PSG without any signs or symptoms of disease.

Abstract
Abstract
Background
Perianal fistulae occurring with Crohn’s disease (CD) are a challenge to treat. Vedolizumab (VDZ) is a gut-selective, monoclonal α 4β7 integrin antibody approved to treat patients (patients) with moderately to severely active CD. Here we report results from ENTERPRISE (NCT02630966; EudraCT 2015-000852-12), a randomised, double-blind, phase 4 trial to evaluate 2 VDZ IV dosing regimens in patients with fistulising CD.
Methods
Patients with moderately to severely active CD and 1–3 draining perianal fistulae received either VDZ 300 mg IV at Weeks (Week) 0, 2, 6, 14, and 22 (VDZ), or the same regimen plus an additional VDZ dose at Wk10 (VDZ+Wk10). The primary endpoint was the proportion of patients with a ≥50% reduction from baseline (BL) in the number of draining fistulae (absence of draining despite gentle finger compression) at Wk30. Secondary endpoints were the proportion of patients with a ≥50% reduction from BL in the number of draining fistulae at Wk22 and Wk30, and the proportion of patients with 100% fistulae closure at Wk30. Patients with missing data at study visits were counted as non-responders. Perianal disease activity index (PDAI), perianal pain score, Van Assche score, gadolinium contrast enhancement by pelvic MRI, and safety were assessed. Study enrolment closed early due to slow recruitment; thus, all analyses are descriptive.
Results
Of the 32 patients with post-BL assessment of fistulae healing (full analysis set, FAS), 28 had ≥1 draining fistula at BL (modified FAS). Median CD duration was 8.5 years (VDZ [n = 14]: 11.2 years; VDZ+ Week 10 [n = 14]: 6.1 years). In each arm, 11 patients (78.6%) had prior anti-tumour necrosis factor therapy at BL; concomitant corticosteroid use was 21.4% (VDZ) and 14.3% (VDZ+ Week 10), and concomitant immunosuppressant use was 28.6% (VDZ) and 21.4% (VDZ+ Week 10). At Wk30, 53.6% of all patients achieved ≥50% decrease in the number of draining fistulae (VDZ: 64.3%; VDZ+ Week 10: 42.9%; Figure 1). The proportion of patients with fistulae response increased rapidly and remained high through Week 30 (Figure 2); 46.4% of patients (VDZ: 57.1%; VDZ+Week 10: 35.7%) achieved ≥50% decrease in the number of draining fistulae at both Weeks 22 and 30. Closure of all fistulae draining at BL was observed at Week 30 in 42.9% of patients (VDZ: 50.0%; VDZ+ Week 10: 35.7%). In the FAS, mean (SD) PDAI scores changed from BL to Weeks 30–4.1 (3.3) and perianal pain scores changed –2.2 (2.7) (table). At Wk30, mean (SD) Van Assche scores and contrast enhancement scores changed –1.1 (3.1) and –9.5 (69.4) from screening, respectively. No new safety signals were observed.
Conclusion
Over half of CD patients treated with VDZ had reductions of ≥50% in the number of draining perianal fistulae. Clinically relevant reductions in draining fistulae were seen as early as Wk2 and maintained through Wk30.

Abstract
OBJECTIVES The rise in carbapenem resistance among Gram-negative bacteria has renewed interest in colistin. Recently, the EUCAST-CLSI Polymyxin Breakpoints Working Group declared that broth microdilution (BMD) is the only valid method for colistin susceptibility testing. BMD is not easily incorporated into the routine work of clinical laboratories, and usually this test is incorporated serially, resulting in delayed susceptibility reporting. We tested a strategy of combining VITEK® 2 with a 2 μg/mL colistin agar dilution (VITEK® 2/AD) screening plate to improve performance and time to reporting of colistin susceptibility. METHODS Colistin susceptibility for 364 clinical isolates was determined by VITEK® 2/AD and compared with the reference standard BMD according to the ISO 20776-1:2007 and CLSI guidelines. The EUCAST colistin susceptibility breakpoint of ≤2 μg/mL was used. Escherichia coli NCTC 13846 served as quality control strain. Agreement, very major error (VME) and major error rates were determined using ISO 20776-2:2007. RESULTS The VME rate for VITEK® 2 alone was 30.6% (15/49, 95% CI 18.3-45.4%), and was reduced to 10.2% (5/49, 95% CI 3.4-22.2%) using the VITEK® 2/AD combined testing. The combined testing had categorical agreement with BMD of 97% (354/364, 95% CI 95.0-98.7%), and a major error (ME) rate of 1.6% (5/315, 95% CI 0.5-3.7%). Using the combined testing, even against challenging strains, 349 (95.8%, 95% CI 93.3-97.7%) colistin susceptibility results could be reported, and only 15 isolates required further analysis by BMD. DISCUSSION Our method is simple to apply and allows rapid reporting of colistin susceptibility.

Abstract
BACKGROUND An important benefit associated with kidney transplantation in women of child-bearing age is increased fertility. We retrospectively evaluated the maternal and fetal complications and evolution of graft function associated with 22 pregnancies post-kidney and kidney-pancreas transplantation, compared with controls without pregnancy post-transplantation, who were matched for gender, year of transplantation, type of donor, age at transplantation, number of transplants, type of transplant (kidney vs kidney-pancreas), and cause of native kidney failure, as well as for renal parameters including serum creatinine and urine protein excretion 1 year before delivery. RESULTS The mean age at time of transplantation was 22.32 (range, 19.45-33.1) years. The mean interval between transplantation and delivery was 75.7 (range, 34-147.8) months. Main maternal complications were pre-eclampsia in 27.3%. The main fetal complications included delayed intrauterine growth (18.2%), preterm deliveries (89.4%), and one death at 3 days postdelivery. The mean serum creatinine level pre-pregnancy was 1.17 (range, 0.7-3.1) mg/dL. Graft failure was higher in the pregnancy group (6 vs 3) but did not differ statistically from the control group, and was associated with creatinine pre-pregnancy (odds ratio [OR], 1.71; 95% confidence interval [CI], 1.15-3.45; P = .04), age at transplantation (1.13 [1.03-1.21]; P = .032), and time of follow-up (2.14 [1.27-2.98]; P = .026). Delta serum creatinine was not different in both groups: 1.05 ± 0.51 versus 0.99 ± 0.92 mg/dL, study versus control group, respectively (P = .17). CONCLUSION Pregnancy after kidney transplantation is associated with serious maternal and fetal complications. We did not observe a significantly increased risk of graft loss or reduced graft function in comparison with recipients with similar clinical characteristics.

Abstract
Purpose The creation of a vascular access is necessary in hemodialysis patients, including those with marginal vessels. Upper arm fistulae are attractive due to the ease of creation and of achieving high access flow rates. Cephalic arch stenosis (CAS) can lead to failure of upper arm fistulae and is increasingly identified. We hypothesized that CAS is promoted by high blood flow rates, brachiocephalic fistulae, and an angle of cephalic vein insertion approaching 90 degrees. Methods All patients requiring a fistulogram between January 2004 and May 2006 had surveillance fluoroscopy of the central veins. Demographic, clinical and laboratory parameters were collected and the angle of the cephalic vein insertion measured by 3 blinded independent observers. Results Fifty-eight patients had fistulograms and CAS was detected in 18 subjects. Significant differences between the CAS and non-CAS groups were brachiocephalic fistula site (p=0.046), access flow (mL/min) (p=0.012), and absence of diabetes (p=0.03). Univariate predictors of CAS include access flow (per 100 mL/min) (p=0.042), platelet count (p=0.031) and calcium-phosphate product (p=0.026). The relationship of brachiocephalic site and CAS was confounded by access flow [(per 100 mL/min)*brachiocephalic fistula site (p=0.016)] and fistula age [brachiocephalic fistula site*fistula age (p=0.017)]. In multivariate analysis, renovascular disease, calcium-phosphate product, platelet count and access flow (per 100 mL/min)*brachiocephalic fistula predicted CAS (p<0.001, Negelkerke's R-Square= 0.55). The angle of insertion of the cephalic vein was not predictive for CAS. Conclusions CAS may be a long-term consequence of high blood flow rates. The interaction of access flow and brachiocephalic fistula supports the hypothesis that high flow through a brachiocephalic fistula promotes CAS. The multiple factors influencing cephalic arch remodeling require further research.

Abstract
BACKGROUND Serum amyloid A (SAA) is a major acute phase protein in horses. A new point-of-care (POC) test for SAA (Stablelab) is available, but studies evaluating its analytical accuracy are lacking. OBJECTIVES To evaluate the analytical performance of the SAA POC test by 1) determining linearity and precision, 2) comparing results in whole blood with those in serum or plasma, and 3) comparing POC results with those obtained using a previously validated turbidimetric immunoassay (TIA). STUDY DESIGN Assay validation. METHODS Analytical validation of the POC test was done in accordance with American Society of Veterinary Clinical Pathology guidelines using residual equine serum/plasma and whole blood samples from the Clinical Pathology Laboratory at the University of California-Davis. A TIA was used as the reference method. We also evaluated the effect of haematocrit (HCT). RESULTS The POC test was linear for SAA concentrations of up to at least 1000 μg/mL (r = 0.991). Intra-assay CVs were 13, 18 and 15% at high (782 μg/mL), intermediate (116 μg/mL) and low (64 μg/mL) concentrations. Inter-assay (inter-batch) CVs were 45, 14 and 15% at high (1372 μg/mL), intermediate (140 μg/mL) and low (56 μg/mL) concentrations. SAA results in whole blood were significantly lower than those in serum/plasma (P = 0.0002), but were positively correlated (r = 0.908) and not affected by HCT (P = 0.261); proportional negative bias was observed in samples with SAA>500 μg/mL. The difference between methods exceeded the 95% confidence interval of the combined imprecision of both methods (15%). MAIN LIMITATIONS Analytical validation could not be performed in whole blood, the sample most likely to be used stall side. CONCLUSION The POC test has acceptable accuracy and precision in equine serum/plasma with SAA concentrations of up to at least 1000 μg/mL. Low inter-batch precision at high concentrations may affect serial measurements, and the use of the same test batch and sample type (serum/plasma or whole blood) is recommended. Comparison of results between the POC test and the TIA is not recommended.

Abstract
Alzheimer's disease (AD) causes alterations of brain network structure and function. The latter consists of connectivity changes between oscillatory processes at different frequency channels. We proposed a multi-layer network approach to analyze multiple-frequency brain networks inferred from magnetoencephalographic recordings during resting-states in AD subjects and age-matched controls. Main results showed that brain networks tend to facilitate information propagation across different frequencies, as measured by the multi-participation coefficient (MPC). However, regional connectivity in AD subjects was abnormally distributed across frequency bands as compared to controls, causing significant decreases of MPC. This effect was mainly localized in association areas and in the cingulate cortex, which acted, in the healthy group, as a true inter-frequency hub. MPC values significantly correlated with memory impairment of AD subjects, as measured by the total recall score. Most predictive regions belonged to components of the default-mode network that are typically affected by atrophy, metabolism disruption and amyloid-β deposition. We evaluated the diagnostic power of the MPC and we showed that it led to increased classification accuracy (78.39%) and sensitivity (91.11%). These findings shed new light on the brain functional alterations underlying AD and provide analytical tools for identifying multi-frequency neural mechanisms of brain diseases.

Abstract
BACKGROUND Dialysis patients have a suboptimal response to hepatitis B (HBV) vaccination. This study aimed to compare the immunogenicity of two vaccines: the third-generation Sci-B-Vac™ vs. the second-generation Engerix B®. The cohort included two groups of dialysis patients: naïve and previously vaccinated non-responders. Primary endpoints were antibody titers ≥10 IU/L at 3 and 7 month post-vaccination. Secondary objectives were seroprotection rates in vaccine-naïve patients and in previously vaccinated non-responders. METHODS Eighty-six patients were assigned to vaccine (Sci-B-Vac™ or Engerix B®) using computer-generated randomization, stratified by age, gender, diabetes, and previous HBV vaccination. Sci-B-Vac™ was administered in three doses, 10 μg, at 0, 1, and 6 months in naïve patients; or 20 μg in previously vaccinated non-responders. Engerix B® included four doses, 40 μg at 0, 1, 2, and 6 months. RESULTS Each group had 43 patients. Seroconversion was 69.8% with Engerix B® vs. 73.2% with Sci-B-Vac™. Antibody titers at 7 months were higher with Sci-B-Vac™ (266.4 ± 383.9, median 53.4) than with Engerix® (193.2 ± 328.9, median 19). However, these differences were not significant, perhaps due to a suboptimal sample size. CONCLUSIONS This study suggests comparable immunogenicity for both vaccines. Thus, we cannot reject the null hypothesis that there is no difference in seroconversion by vaccine type. It is noteworthy that naïve patients were vaccinated with a standard dose of Sci-B-Vac™, while Engerix B® was administered at a double dose. Similarly, although mean antibody titer levels in the Sci-B-Vac™ group were higher than in the Engerix® group, this difference did not reach significance. Consequently, a future clinical trial should recruit a larger cohort of patients, using a standard double-dose protocol in both groups.

Abstract
Rapid identification of the causative pathogen in patients with bacteremia allows adjustment of antibiotic therapy and improves patient outcomes. We compared in vitro and real-life time to detection (TTD) of two blood culture media, BacT/Alert FA (FA) and BacT/Alert FA Plus (FA Plus), for the nine most common species of bacterial pathogens recovered from blood samples. Experimental data from simulated cultures was compared with microbiology records of TTD for both culture media with growth of the species of interest in clinical blood cultures. In the experimental conditions, median TTD was 3.8 hours (23.9 %) shorter using FA Plus media. The magnitude of reduction differed between species. Similarly, in real life data, FA Plus had shorter TTD than FA media; however, the difference between culture media was smaller, and median TTD was only 1 hour (8.5 %) less. We found shorter TTD with BacT/Alert FA Plus culture media, both experimentally and in real-life conditions and unrelated to antibiotic neutralization, highlighting the importance of appropriate blood culture media selection.

Abstract
SETTING This report describes the management and outcome of neonatal intensive care unit (NICU) and paediatric ICU (PICU) exposure to a 26-day-old premature infant with congenital tuberculosis (TB). DESIGN The infant's mother underwent chest X-ray (CXR) and sputum culture. Contacts of the infant were identified. Tuberculin skin tests (TSTs) were performed on 97 infants and children, 156 NICU and PICU visitors and 115 health care workers. RESULTS The mother's sputum culture was positive for Mycobacterium tuberculosis. No TST conversion occurred in the exposed NICU infants. All neonates received prophylactic isoniazid (INH). One exposed child in the PICU had TST conversion with normal CXR and completed 9 months of INH without developing active disease; 22 (14%) PICU and NICU visitors and 3 NICU personnel had TST conversion without evidence of disease. CONCLUSIONS The sequence of events described here demonstrates the difficulty in diagnosis and management of TB in this age group. Transmission of TB in NICU and PICUs is unusual but can occur, and calls for a systematic approach to investigation of the exposed infants, family members and health care providers.

Abstract
BACKGROUND AND AIMS The ECCO-EpiCom study investigates the differences in the incidence and therapeutic management of inflammatory bowel diseases [IBD] between Eastern and Western Europe. The aim of this study was to analyse the differences in the disease phenotype, medical therapy, surgery, and hospitalization rates in the ECCO-EpiCom 2011 inception cohort during the first year after diagnosis. METHODS Nine Western, five Eastern European centres and one Australian centre with 258 Crohn's disease [CD], 380 ulcerative colitis [UC] and 71 IBD unclassified [IBDU] patients [female/male: 326/383; mean age at diagnosis: 40.9 years, SD: 17.3 years] participated. Patients' data were registered and entered in the web-based ECCO-EpiCom database [www.epicom-ecco.eu]. RESULTS In CD, 36 [19%] Western Europe/Australian and 6 [9%] Eastern European patients received biological therapy [p = 0.04], but the immunosuppressive [IS] use was equal and high in these regions [Eastern Europe vs Western Europe/Australia: 53% vs 45%; p = 0.27]. Surgery was performed in 17 [24%] CD patients in Eastern Europe and 13 [7%] in Western Europe/Australia [p < 0.001, pLogRank = 0.001]. Of CD patients from Eastern Europe, 24 [34%] were hospitalized, and 39 [21%] from Western Europe/Australia, [p = 0.02, pLogRank = 0.01]. In UC, exposure to biologicals and colectomy rates were low and hospitalization rates did not differ between these regions during the 1-year follow-up period [16% vs 16%; p = 0.93]. CONCLUSIONS During the first year after diagnosis, surgery and hospitalization rates were significantly higher in CD patients in Eastern Europe compared with Western Europe/Australia, whereas significantly more CD patients were treated with biologicals in the Western Europe/Australian centres.
