Abstract
An Indian migrant presented with increasing neurological symptoms after an acute influenza B infection. We diagnosed progressive neurotuberculosis—a rare and difficult case of tuberculosis and influenza co-infection. It highlights the importance of broad-based diagnostics in people from low- and middle-income countries, taking into account unusual manifestations of tuberculosis.

Abstract
Abstract
Background
Transcutaneous edge-to-edge repair (TEER) has become a treatment option for selected patients with severe mitral regurgitation (MR). Analysis of the COAPT trial indicated patients with diabetes mellitus to have higher death rates and a trend to higher rates of heart failure hospitalization (HFH) than those without diabetes. However, in that study only patients with secondary MR with specific criteria were included and there are only limited data on diabetes patients in real-world settings.
Purpose
This study sought to evaluate safety and efficacy of TEER in patients with diabetes mellitus in comparison to non-diabetics.
Methods
In this monocentric study 340 consecutive patients with severe primary and secondary MR who underwent TEER were included. Immediate results of the procedure, intrahospital as well as one-year outcome were compared between patients with and without diabetes.
Results
Diabetes was present in 109 patients (32%) of the study group. Patients with diabetes were younger (75±8 vs. 78±8 years; p=0.003), had more often ischemic cardiomyopathy (68% vs. 48%, p<0.001), previous coronary-artery bypass graft (35% vs. 20%; p=0.002) and arterial hypertension (89% vs. 75%; p<0.001) compared to those without diabetes. All other baseline clinical and imaging characteristics including NYHA class, left ventricular dimensions and function (ejection fraction: 38±13% vs. 41±14%; p=0.10) as well as severity of MR were not different between both patient groups (Table 1).
Success of the procedure was comparable between patients with and without diabetes (95% vs. 95%; p=0.84). There was no difference in intrahospital mortality between both groups (5.5% vs. 4.8%; p=0.98). At one-year follow up, there was no difference regarding all-cause mortality (24.2% vs. 23.0%; p=0.72), HFH (37.4% vs. 31.0%, p=0.23), NYHA class (p=0.11) or MR severity (p=0.20) between both groups (Table 2).
Conclusion
In contrast to previous published data on patients with diabetes and severe MR TEER seems to be similar safe and effective in a real-world setting compared to non-diabetics.

Abstract
BackgroundRituximab (RTX) is an effective remission-induction treatment in ANCA-associated vasculitides (AAVs). Some reports have suggested that it might be effective also in Eosinophilic Granulomatosis with Polyangiitis (EGPA), to induce and maintain remission of vasculitic manifestations [1,2]. However, its effects for preventing respiratory relapses seem to be poor. Mepolizumab (Mepo) (both 100 and 300mg/month) is effective in improving respiratory manifestations and lung function, while partially controlling also systemic activity [3,4]. Isolated case reports further indicate that the sequential therapy with RTX and Mepo might be effective [5-7].ObjectivesThe study aimed to investigate the efficacy and safety of a therapeutic regimen based on sequential RTX and Mepo for the control of EGPA.MethodsA multicenter, retrospective, cohort study was conducted on adult patients diagnosed with EGPA according to the ACR classification criteria [8] or MIRRA trial criteria [3]. Only patients who received induction therapy with RTX (any dosage), and subsequent treatment with Mepo (100-300 mg/4 weeks) within 12 months from last RTX administration were included. Patients receiving other induction therapies between RTX and Mepo were excluded. The effectiveness of sequential RTX and Mepo was assessed in terms of disease activity (by the Birmingham Vasculitis Activity Score, BVAS) and daily corticosteroid dosage. Safety data were also collected.ResultsThirty-four EGPA patients treated with sequential RTX and Mepo were included (59% females, median age of 51 years (IQR 40-58); 41% ANCA positive).In most cases (26/34; 76%), RTX was started at the dosage of 1g q2w, and all except two patients had active disease at time of RTX beginning [median BVAS of 9 (IQR 6-14)]. Specifically, most patients started RTX for the control of systemic manifestations (19/34; 56%), or of both systemic and respiratory symptoms (11/34; 32%). All except one patient were receiving oral corticosteroids, at a median dosage of 25 mg/day (10-38).Mepo was started after a median of 14 months (6-23) from RTX initiation and after a median of 5 months (IQR 3-11) from the last RTX administration. Mepo was used at the dosage of 100mg/4 weeks in 32/34 (94%), mostly for the control of respiratory manifestations (25/34, 74%). At the time of starting Mepo, the median BVAS was 4 (2-8), and median prednisolone dose 10 mg/day (7-15). After a median follow-up of 28 months (IQR 23-33) from starting Mepo, the median BVAS decreased to 1.5 (IQR 0-4) and the median corticosteroid dosage to 5 mg/day (2.5-5), with 7/34 (21%) patients being off steroids. At last follow-up, most patients were off-RTX (28/34), typically due to stable disease remission (20/34; 59%).Both RTX and Mepo were well-tolerated; 5 patients had adverse events on RTX (none serious), and 5 on Mepo (including one serious infection).ConclusionSequential use of RTX and Mepo seems to be effective for remission induction and maintenance in EGPA.References[1]Emmi, Ann Rheum Dis, 2018[2]Teixeira, RMD Open, 2019 3.

Abstract
Background:Evidence on the efficacy of Mepolizumab (MEPO) in Eosinophilic Granulomatosis with Polyangiitis (EGPA) is scarce [1].Objectives:To assess the efficacy and safety of MEPO in real-life clinical practice.Methods:We retrospectively included patients diagnosed with EGPA and treated with MEPO (100 or 300 mg/month). MEPO efficacy was evaluated in the first 12 months in terms of systemic disease and asthma control. The occurrence of any adverse event (AE) was recorded.Results:142 patients were included (38% males; median age 46.4 (IQR 36.7-54.4); 110 and 32 on MEPO 100 and 300 mg/month, respectively). General, ear-nose-throat, pulmonary, and neurological symptoms significantly decreased during treatment (table 1). MEPO accounted for a significant reduction in the BVAS (figure 1) and for a steroid sparing effect (figure 2). The proportion of patients with asthma attacks decreased by 90% at 12 months compared to t0, and asthma-related emergency accesses dropped from 17.4% to 2.3%. Overall, 21.1% of patients had a non-serious AE.Table 1.Control of clinical symptomsMEPO beginning (t0)3 monthsp-value(t3 vs t0)6 monthsp-value(t6 vs t0)12 monthsp-value(t12 vs t0)N obsN=142N=135N=123N=89General symptoms40 (28.2%)17 (12.6%)<0.00119 (15.5%)<0.00113 (14.6%)0.002Cutaneous manifestations13 (9.2%)6 (4.4%)0.0085 (4.1%)0.0254 (4.5%)0.180ENT manifestations106 (74.7%)52 (38.5%)<0.00144 (35.8%)<0.00129 (32.6%)<0.001Pulmonary manifestations130 (91.6%)59 (43.7%)<0.00139 (31.7%)<0.00128 (31.5%)<0.001Cardiac manifestations6 (4.2%)2 (1.5%)0.0832 (1.6%)0.08300.157Intestinal manifestations10 (7.0%)1 (0.7%)0.0054 (3.3%)0.0593 (3.4%)0.059Renal manifestations5 (3.5%)3 (2.2%)0.41400.0461 (1.1%)0.317Neurological manifestations36 (25.4%)22 (16.3%)0.01218 (14.6%)0.00310 (11.2%)0.035Figure 1.Changes in BVASFigure 2.Steroid treatmentConclusion:MEPO effectively controlled systemic and respiratory EGPA symptoms in a large European cohort, with no major safety concerns.References:[1]Wechsler et al.

Abstract
Meloidogyne aegracyperi n. sp. is described from roots of purple nutsedge in southern New Mexico, USA. Mature females are small (310–460 µm), pearly white, with their egg masses completely contained inside root galls. The neck is often at a 90 to 130° angle to the protruding posterior end with the perineal pattern. The distance of the dorsal esophageal gland orifice (DGO) to the base of the stylet is relatively long (4.0–6.1 µm), and the excretory pore is level with the base of the stylet. The anterior portion of the rounded lumen lining of the metacorpus contains 3 to 10 small vesicles. The perineal pattern has a rounded dorsal arch with a tail terminal area that is smooth or marked with rope-like striae. Only two males were found. The body twists 90° throughout its length. The DGO to the base of the stylet is long (3.0–3.3) µm. The cephalic framework of the second-stage juvenile is weak, and the stylet is short (10.1–11.8 µm). The DGO to the base of the stylet is long (3–5 µm). The tail is very long (64–89 µm) and the hyaline portion of the tail is very narrow, making the tail finely pointed. Eggs are typical for the genus and vary in length (85.2–99.8 µm) and width (37.1–48.1 µm), having a L/W ratio of (2.1–2.6). Maximum likelihood phylogenetic analyses of the different molecular loci (partial 18S rRNA, D2-D3 of 28S rRNA, internal transcribed spacer (ITS) rRNA, cytochrome oxidase subunit II (COII)-16S rRNA of mitochondrial DNA gene fragments and partial Hsp90 gene) placed this nematode on an independent branch in between M. graminicola and M. naasi and a cluster of species containing M. chitwoodi. M. fallax, and M. minor. Greenhouse tests showed that yellow and purple nutsedge were the best hosts, but perennial ryegrass, wheat, bentgrass, and barley were also hosts.

Abstract
Abstract
Background
Percutaneous closure of patent foramen ovale (PFO) after cryptogenic stroke (CS) is strongly recommended in the current guidelines. Most available evidence has been obtained from randomized studies in which Amplatzer PFO occluder device or Groe occluder device were implanted. Several occluder devices are used off-label for percutaneous treatment of PFO. Rate of recurrent CS and rate of residual shunting after percutaneously occlusion of PFO varies between different occlusion devices. To date, there are no randomized clinical studies that compare the effectivity and safety of several devices in patients with CS.
Aim
The aim of this study was to compare rate of residual shunting and recurrent CS after percutaneus treatment of PFO with the most common used PFO occluder devises.
Methods
This was a retrospective, non-randomized, monocenter study. Between 2008 and 2014, all patients with CS or transient ischemic attack (TIA) treated with transcatheter occlusion of PFO with Amplatzer PFO occlusion device or Occlutech occlusion device were included. Patients were followed up at 1 and 6 months with contrast-enhanced transesophageal echocardiography (TEE), and at 3 months with contrast-enhanced transthoracic echocardiography. Primary endpoint was residual shunting at 6 months. Secondary endpoint was recurrent CS or TIA at 6 months after the procedure.
Results
220 consecutive patients (57±12 year, 131 men) were treated with Amplanz PFO occlusion device (140 patients) or Occlutech PFO occlusion device (80 patients) after CS or TIA. Procedural success was 100% in both groups. Residual shunting was observed directly after the procedure in 26 patients in the Amplatzer group and 22 patients in the Occlutech group (19% and 27%, respectively; p=0.003), at 1 months follow (15% and 25%, respectively; p=0.064) and at 6 months (9% and 16%, respectively; p=0.024). There was no significant difference between both groups according recurrent CS (0.7% and 0%, respectively; p=0.449). At 6 months follow up atrial fibrillation was detected in 2 patients from Amplatzer group and 5 patients from Occlutech group (1.4% and 6.0%, respectively; p=0.050). Death, aortic erosion and pericardial effusion was not observed in both groups.
Clinical and echocardiographic outcome Variable Amplatzer occluder device (N=140) Occlutech occluder device (N=80) p-value Clinical outcome at 6 months follow up Death, n (%) 0 (0%) 0 (0%) 1.000 Stroke, n (%) 1 (1%) 0 (0%) 0.449 Transient ischemic attack, n (%) 0 (0%) 0 (0%) 1.000 Atrial fibrillation, n (%) 2 (1.4%) 5 (6%) 0.050 Aortic erosion, n (%) 0 (0%) 0 (0%) 1.000 Pericardial effusion, n (%) 0 (0%) 0 (0%) 1.000 Echocardiographic Outcome at 6 months follow up Residual shunting after Implantation directly, n (%) 26 (19%) 22 (27%) 0.003 Residual shunting at one month, n (%) 21 (15%) 20 (25%) 0.064 Residual shunting at 6 months, n (%) 13 (9%) 16 (20%) 0.024
Conclusion
Percutaneous treatment of PFO after CS or TIA with Amplatzer PFO occluder device was associated with lower rate of residual shunting and lower rate of atrial fibrillation at 6 months follow up, whereas rate of recurrent CS and TIA was comparable between both groups.

Abstract
Background and Purpose: To date, imaging studies quantifying the amount of vasogenic edema reduction (VE) in patients with brain metastases (BM) treated with glucocorticoids (GC) have included a very limited number of patients and showed ambiguous results. Here, we aim to determine the radiological effect of GC on VE in BM patients in a large cohort with multiple primary tumor entities in a cross-sectional approach. Materials and Methods: This monocentric retrospective study includes 299 patients first-ever diagnosed with 2,759 intra-axial BM on the respective MRI. 126/299 patients received GC prior to MRI due to mass effect of edema on cranial CT scan and clinical symptoms (GC-pos) and 173 patients did not (GC-neg). GC dose was documented in 85/126 patients. All BM and their respective VE were semi-automatically segmented on post-contrast T1-weighted images. Results: VE volumes were higher in GC-pos compared to GC-neg (p = 0.009) and did not correlate with GC dose. Multivariate linear regression analysis with interaction terms on the assumption that BM volume and BM number influence the probability of GC administration shows that large and higher numbers of BM under GC treatment generate less VE than without (p < 0.001 and p = 0.038, respectively). The primary tumor type and total BM volume did not influence VE volume. Conclusion: Use of GC is especially effective for treatment of VE formation in patients with larger and multiple BM regardless of primary tumor type and dosage. However, based on the present data a direct causative relationship between GC and VE cannot be proven.

Abstract
Background and Aims: Vascular border zones and the gray-white matter junction are preferred sites for the development of brain metastases (BM), whereas microvascular lesions are known to be a protective factor. In this proof of concept study, we aim to study the relationship of blood perfusion and the spatial distribution of BM. Materials and Methods: An average CT perfusion atlas of 107 healthy patients was created. Voxel-wise reference perfusion values were extracted from BM-negative and BM-positive regions in a second cohort of 100 untreated patients harboring 809 BM confirmed by MRI. A comparison of regional perfusion values was performed using the independent t-test. Results: In contrast to supratentorial BM that develop preferably in areas with lower CBV/CBF and longer MTT/TTP compared to the average regional perfusion (p < 0.001), infratentorial BM showed a higher CBV/CBF and shorter MTT/TTP (p < 0.001). Conclusion: Our results imply differing pathophysiological mechanisms underlying supra- and infratentorial BM spreading. The inverse perfusion patterns may result from differences in vascular supply, hemodynamic requirements, and/or production of pro-angiogenic factors.

Abstract
OBJECTIVE To identify the determinants of natural cause mortality in a cohort of individuals with serious mental illness assessed prospectively. METHOD Persons with schizophrenia (n = 789) and bipolar disorder (n = 498), mean age of 38 (s.d. 12.6) years, underwent an in-person clinical assessment. They also had a blood sample drawn from which infectious disease markers were measured. Mortality was subsequently determined utilizing data from the National Death Index following a period of up to 16.9 years. RESULTS A total of 6.8% (87 of 1287) of persons died of natural causes. Mortality was predicted in a multivariate model by baseline cigarette smoking (RR = 6.29, 95% CI 1.41, 3.72, P = 0.00076); divorced or widowed status (RR = 1.90, CI 1.21, 2.99); reduced cognitive score (RR = 0.73, CI 0.61, 0.87); receipt of antidepressant medication (RR = 1.74, CI 1.12, 2.71); elevated levels of antibodies to Epstein-Barr virus (EBV) (RR = 1.29, CI 1.01, 1.66); and a genitourinary (RR = 1.82, CI 1.16, 2.86), respiratory (RR = 1.82, CI 1.16, 2.86), or cardiac (RR = 2.09, CI 1.33, 3.29) condition. There was an additive effect of smoking and both a cardiac and a respiratory condition but not elevated EBV antibody levels. CONCLUSION Smoking is a modifiable behaviour which is associated with mortality in this population.

Abstract
How has evolution led to the variation in behavioural phenotypes (personalities) in a population? Knowledge of whether personality is heritable, and to what degree it is influenced by the social environment, is crucial to understanding its evolutionary significance, yet few estimates are available from natural populations. We tracked three behavioural traits during different life-history stages in a pedigreed population of wild house sparrows. Using a quantitative genetic approach, we demonstrated heritability in adult exploration, and in nestling activity after accounting for fixed effects, but not in adult boldness. We did not detect maternal effects on any traits, but we did detect a social brood effect on nestling activity. Boldness, exploration and nestling activity in this population did not form a behavioural syndrome, suggesting that selection could act independently on these behavioural traits in this species, although we found no consistent support for phenotypic selection on these traits. Our work shows that repeatable behaviours can vary in their heritability and that social context influences personality traits. Future efforts could separate whether personality traits differ in heritability because they have served specific functional roles in the evolution of the phenotype or because our concept of personality and the stability of behaviour needs to be revised.

Abstract
Purpose There is growing evidence that a perihematomal area of restricted diffusion (PDR) exists in intraparenchymal hemorrhages (IPH) within 1 week of symptom onset (SO). Here, we study characteristics and the clinical impact of the PDR in patients with hyperacute (≤ 6 hours from SO) IPH by means of apparent diffusion coefficient (ADC). Methods This monocentric, retrospective study includes 83 patients with first-ever primary IPH from 09/2002-10/2015. 3D volumetric segmentation was performed for the IPH, PDR, and perihematomal edema (PHE) on fluid-attenuated inversion recovery, T2*/susceptibility weighted images, and ADC images. Results A PDR was seen in 56/83 patients (67.5%) presenting with hyperacute IPH. Multivariate logistic regression analysis revealed every 10-year increase of age (HR 1.929, 95% CI 1.047–3.552, P = .035) and male gender (HR 5.672, 95% CI 1.038–30.992, P = .045) as significant predictors of the presence of a PDR, but not IPH size, IPH location, nor National Institutes of Health Stroke Scale Score (NIHSS) at admission. We found no difference in NIHSS at discharge, hematoma removal, or mortality rate in PDR-positive patients. ADC values of the PDR show a step-wise normalization with increasing time from SO. Conclusions Occurrence of a PDR is a common finding in supratentorial hyperacute IPH, but shows no adverse short-term clinical impact. It may represent transient oligemic and metabolic changes.

Abstract
AIM The aim of this study was a comparison of the handling and acceptance of two kinds of interdental brushes (interdental brush with a handle [HB] and a newly invented interdental cleaning device [NB]). METHODS AND MATERIALS In a randomized crossover trial, 40 test subjects with an average number of 23.5 interdental areas were examined. At two appointments with a "washout" period of one week, the volunteers tried out both cleaning tools (HB and NB). They were asked to clean as many interdental spaces as possible. The percentage of spaces, which could be reached, is the IRI (Interdental Reachability Index). Furthermore, subjective impressions were determined. RESULTS The average IRI using HB was 64% compared to 80% using of NB (P<.001); 62.5% of the volunteers found the cleaning with HB painful and 15% the cleaning with NB. The subjective feeling after cleaning was 1.75 with NB compared to 2.2 with HB (P=.015), grading the feeling, from 1 for "very good" to 5 for "poor." The acceptance of regular interdental hygiene was rated 1.95 in the case of the NB and 2.85 in the case of the HB. After both appointments, the test subjects declared that they would use the NB 3.05 times and the HB 1.78 times a week. CONCLUSION This study shows that the test subjects reached more interdental spaces with NB than with the HB. NB can improve the usage of interdental brushes. Regarding subjective comfort, participants also favoured NB over HB.

Abstract
No prior systematic study on the extent of vasogenic edema (VE) in patients with brain metastases (BM) exists. Here, we aim to determine 1) the general volumetric relationship between BM and VE, 2) a threshold diameter above which a BM shows VE, and 3) the influence of the primary tumor and location of the BM in order to improve diagnostic processes and understanding of edema formation. This single center, retrospective study includes 173 untreated patients with histologically proven BM. Semi-manual segmentation of 1416 BM on contrast-enhanced T1-weighted images and of 865 VE on fluid-attenuated inversion recovery/T2-weighted images was conducted. Statistical analyses were performed using a paired-samples t-test, linear regression/generalized mixed-effects model, and receiver-operating characteristic (ROC) curve controlling for the possible effect of non-uniformly distributed metastases among patients. For BM with non-confluent edema (n = 545), there was a statistically significant positive correlation between the volumes of the BM and the VE (P < 0.001). The optimal threshold for edema formation was a diameter of 9.4 mm for all BM. The primary tumors as interaction term in multivariate analysis had a significant influence on VE formation whereas location had not. Hence VE development is dependent on the volume of the underlying BM and the site of the primary neoplasm, but not from the location of the BM.

Abstract
156 Background: Perioperative Ctx has become standard of care for LAGC. Duration of pre- and post-op Ctx is a matter of debate. Our study evaluated effects of varying durations of pre- and post-op Ctx on PFS and OS. Secondary endpoints were toxicity, reasons for cessation of Ctx and response. We compared the outcome to a group of pts receiving no perioperative Ctx as an internal control. Methods: Pts with LAGC were included in a prospective cohort trial from a single institution from 2007 to 2015. Inclusion criteria were T1-T4, N0-3, M0, AEG (n=27) or gastric cancers (n=65). Initial therapy decisions were made by an interdisciplinary tumor board for all pts. Pts received DDP/5-FU (qw d28 mod FFCD-Protocol, Ychou et al. JCO 2011) for 2 mo, and a 3rd mo of pre-op Ctx in case of non-progression after 2 mo and proceeded to Ctx after surgery for a planned total of six mo of Ctx. Results: 92 pts (53 m; 39 f pts) with a median age of 69 ys (range 33-96) were included. A total of 74 pts were recommended periop Ctx and 18 primary surgery (S). A total of 67 (91%) of the periop Ctx received pre-op Ctx (NA) of which 47 (64%) received 3 mo of pre-op Ctx, 19 (26%) two mo, 1 pt (1%) one mo, and 7 pts refused preop Ctx (9%) of which only 3 proceeded to surgery. Only 53 pts (72 %) received post-op Ctx; 25 pts (34%) received three mo, 9 pts (12 %) two mo, and another 10 pts (14 %) one mo of postop Ctx. Nine pts (13%) in the NA group and 20 pts (39%) in the post-op Ctx group had to stop Ctx due to toxicity after 1 (n=11) and <2 (n=9) mo of Ctx. Only 23 pts (31%) received the planned pre- and postop Ctx of 6 mo in total. Up to 07/2016 a total of 36 deaths were observed (39%). 5 yr PFS was 49% in the group of periop Ctx vs 14% in the S group. PFS in pts receiving a total of < 4 mo of Ctx was 36% vs. 61% in pts receiving 6 mo of Ctx. 3 yr OS was 19% in the S group vs 48% in the Ctx group. The OS in pts receiving < 4 mo was 34% vs.43% in pts with 6 mo Ctx. A pCR after preop Ctx was observed in 2 pts, a PR in 47 pts, a SD in 12 pts, while a PD occurred in 3 pts only. Conclusions: Pre-op Ctx was considerably better tolerated than post-op Ctx and led to fewer Tx cessations. We found a better PFS for pts with >4 mo of periop Ctx, as well as OS was affected by a shorter duration of periop Ctx.

Abstract
BACKGROUND Paper food and gastrointestinal (GI) symptom journals are used to help irritable bowel syndrome (IBS) patients determine potential trigger foods. The primary aim of this study was to evaluate the feasibility, usability, and clinical utility of such journals as a data collection tool. A secondary aim was to explore a method for analyzing journal data to describe patterns of diet and symptoms. METHODS Participants (N=17) were asked to log three sets of 3-day food and symptom journals over a 15-day period. Feasibility was evaluated by journal completion rates, symptom logging compliance, and logging fatigability. The feasibility, usability, and clinical utility of journaling were also assessed by a customized evaluation and exit interview. For each journal, regression analyses were conducted to examine relationships between key meal nutrients and subsequent symptoms. KEY RESULTS Most participants were young (mean age 35±12) Caucasian (N=13) women (N=14). Journal completion rates were 100% for all participants with no logging fatigability. Over half perceived paper journaling of food and symptoms as feasible, usable, and clinically useful. Thirteen participants demonstrated a strong association with at least one symptom and meal nutrient. Patterns of associations differed among participants. CONCLUSIONS AND INFERENCES Paper journaling of food and GI symptoms for 9 days over a 15-day period appeared to be a feasible and usable data collection tool for IBS patients. Over half perceived journaling as at least somewhat clinically useful. Findings from this study support the anecdote that food trigger(s) and associated symptom(s) vary for each individual.

Abstract
A high sensitivity multi-channel far infrared laser diagnostics with switchable interferometry and polarimetry operation modes for the advanced neutral beam-driven C-2U field-reversed configuration (FRC) plasmas is described. The interferometer achieved superior resolution of 1 × 1016 m-2 at >1.5 MHz bandwidth, illustrated by measurement of small amplitude high frequency fluctuations. The polarimetry achieved 0.04° instrument resolution and 0.1° actual resolution in the challenging high density gradient environment with >0.5 MHz bandwidth, making it suitable for weak internal magnetic field measurements in the C-2U plasmas, where the maximum Faraday rotation angle is less than 1°. The polarimetry resolution data is analyzed, and high resolution Faraday rotation data in C-2U is presented together with direct evidences of field reversal in FRC magnetic structure obtained for the first time by a non-perturbative method.

Abstract
PURPOSE The presence of intraparenchymal hyperattenuations (IPH) on flat-panel computed tomography (FP-CT) after endovascular recanalization in stroke patients is a common phenomenon. They are thought to occur in ischemic areas with breakdown of the blood-brain barrier but previous studies that investigated a mutual interaction are scarce. We aimed to assess the relationship of IPH localization with prethrombectomy diffusion-weighted imaging (DWI) lesions. METHODS This retrospective multicenter study included 27 acute stroke patients who underwent DWI prior to FP-CT following mechanical thrombectomy. After software-based coregistration of DWI and FP-CT, lesion volumetry was conducted and overlapping was analyzed. RESULTS Two different patterns were observed: IPH corresponding to the DWI lesion and IPH exceeding the DWI lesion. The latter showed demarcated infarction of DWI exceeding IPH at 24 h. No major hemorrhage following IPH was observed. Most IPH were manifested within the basal ganglia and insular cortex. CONCLUSION The IPH primarily appeared within the initial ischemic core and secondarily within the penumbral tissue that progressed to infarction. The IPH represent the minimum final infarct volume, which may help in periinterventional decision making.

Abstract
Abstract
Multilayer coextrusion is applied to produce a tape containing layers of alternating electrical properties to demonstrate the potential for using coextrusion to manufacture capacitors. To obtain the desired properties, we develop two filled polymer systems, one for conductive layers and one for dielectric layers. We describe numerical models used to help determine the material and processing parameters that impact processing and layer stability. These models help quantify the critical ratios of densities and viscosities of the two layers to maintain stable layers, as well as the effect of increasing the flow rate of one of the two materials. The conducting polymer is based on polystyrene filled with a blend of low-melting-point eutectic metal and nickel particulate filler, as described by Mrozek et al. (2010). The appropriate concentrations of fillers are determined by balancing measured conductivity with processability in a twin screw extruder. Based on results of the numerical models and estimates of the viscosity of emulsions and suspensions, a dielectric layer composed of polystyrene filled with barium titanate is formulated. Despite the fact that the density of the dielectric filler is less than the metallic filler of the conductive phase, as well as rheological measurements that later showed that the dielectric formulation is not an ideal match to the viscosity of the conductive material, the two materials can be successfully coextruded if the flow rates of the two materials are not identical. A measurable capacitance of the layered structure is obtained.

Abstract
Colonoscopy is the standard technique in the diagnosis and treatment of colorectal neoplasia, but small adenomas and even advanced lesions can be missed during the procedure. With large scale screening colonoscopy programs installed, information on quality of colonoscopy in primary care is essential, but scarcely available. Over a period of 45 months, we prospectively included all those patients in our study, who underwent major colonic surgery at our institution and who had undergone a colonoscopy within 42 days prior to the operation. 89 men and 100 women, median age 71 years, were included. The majority of these operations were performed for colorectal carcinoma (125), other malignant tumors (4), suspected malignancies (6) or large adenomas (14). The pathologist inspected the resected colonic segment, and we compared his findings with the colonoscopy report. Colonoscopies had been performed by 22 doctors in 13 institutions. Median length of the resected colonic segments was 20 cm (range 3 to 135 cm), total length was 41,21 metres. In 14 segments the pathologist identified 28 neoplastic lesions not described in the endoscopy report. Colonoscopy had missed 2 carcinomas, both in the right colon, and a 12 mm tubulo-villous adenoma with high-grade dysplasia. Another 25 tubular adenomas had been missed, 2 measuring 10 mm, 7 between 5 and 9 mm and 16 smaller than 5 mm. We conclude that primary care colonoscopy misses neoplastic lesions in a significant number of procedures. Most of the missed lesions in our high risk group of patients would have been of little clinical consequence. In a small, but clinically important number of cases, however, advanced adenomas and even colorectal carcinomas were missed by endoscopy.

Abstract
Bronchial wall area percent (WA% = 100 × wall area/total bronchial cross sectional area) is a standard computed tomographic (CT) measure of central airway morphology utilized in smokers with chronic obstructive pulmonary disease (COPD). Although it provides significant clinical correlations, the range of reported WA% is narrow. This suggests limited macroscopic change in response to smoking or that remodeling proportionally affects the airway wall and lumen dimensions such that their ratio is preserved. The objective of this study is to assess central airway wall area (WA), lumen area (Ai), and total bronchial area (Ao) from CT scans of 5,179 smokers and 92 never smoking normal subjects. In smokers, WA, Ai, and Ao were positively correlated with forced expiratory volume in 1 s (FEV1) expressed as a percent of predicted (FEV1%), and the WA% was negatively correlated with FEV1% (P < 0.0001 for all comparisons). Importantly, smokers with lower FEV1% tended to have airways of smaller cross-sectional area with lower WA. The increases in the WA% across GOLD stages of chronic obstructive pulmonary disease (COPD) can therefore not be due to increases in WA. The data suggest two possible origins for the WA% increases: 1) central airway remodeling resulting in overall reductions in airway caliber in excess of the decreased WA or 2) those with COPD had smaller native airways before they began smoking. In both cases, these observations provide an explanation for the limited range of values of WA% across stages of COPD.

Abstract
BACKGROUND Minor depression (MinD) and mild cognitive impairment (MCI) are common disorders in late life that often coexist. The aim of the present review is to demonstrate prevalence rates of minor depression in older patients with and without MCI. METHODS Electronic database searches were performed through Medline, ISI Web of Knowledge, Psycinfo, and Cochrane library. Two independent reviewers extracted the original studies based on inclusion criteria: representative study population aged 55 and older, diagnostics of MinD according to DSM. Data on prevalence rates, risk factors, comorbidity and health care usage were analyzed. RESULTS Point prevalence for MinD is higher in medical settings (median 14.4%) than in the community-based settings (median 10.4%) and primary care patients (median 7.7%). Although minor depression is rarely investigated in elderly persons with MCI, nearly 20% of patients with MCI seem to suffer from MinD. No data was found on the prevalence of MCI in patients with MinD. Risk factors associated with MinD include female gender, history of cerebrovascular diseases, generalized anxiety disorder, loneliness, and long-term institutional care. LIMITATIONS Methodological differences of included studies resulted in a broad range of prevalence rates. No data is shown regarding the prevalence of MCI in MinD group due to insufficient evidence. CONCLUSIONS Our review indicates that MinD is frequent in elderly population. MCI among those subjects has not been sufficiently investigated. Future studies based on clinical structured interviews should be performed in longitudinal design in order to differentiate late-life depression from progressive MCI or early manifestation of Alzheimer's disease.

Abstract
Lower visibility of female scientists, compared to male scientists, is a potential reason for the under-representation of women among senior academic ranks. Visibility in the scientific community stems partly from presenting research as an invited speaker at organized meetings. We analysed the sex ratio of presenters at the European Society for Evolutionary Biology (ESEB) Congress 2011, where all abstract submissions were accepted for presentation. Women were under-represented among invited speakers at symposia (15% women) compared to all presenters (46%), regular oral presenters (41%) and plenary speakers (25%). At the ESEB congresses in 2001–2011, 9–23% of invited speakers were women. This under-representation of women is partly attributable to a larger proportion of women, than men, declining invitations: in 2011, 50% of women declined an invitation to speak compared to 26% of men. We expect invited speakers to be scientists from top ranked institutions or authors of recent papers in high-impact journals. Considering all invited speakers (including declined invitations), 23% were women. This was lower than the baseline sex ratios of early-mid career stage scientists, but was similar to senior scientists and authors that have published in high-impact journals. High-quality science by women therefore has low exposure at international meetings, which will constrain Evolutionary Biology from reaching its full potential. We wish to highlight the wider implications of turning down invitations to speak, and encourage conference organizers to implement steps to increase acceptance rates of invited talks.
