Abstract
INTRODUCTION Allergen-specific immunotherapy (AIT) is the only disease-modifying treatment in allergic airway diseases. Underlying immunological mechanisms and candidate biomarkers, which may be translated into predictive/surrogate measures of clinical efficacy, remain an active area of research. The aim of this study was to evaluate Pollinex Quattro (PQ) Grass AIT induced immunomodulatory mechanisms, based on transcriptome profiling of peripheral blood mononuclear cells. METHODS 119 subjects with grass pollen induced seasonal allergic rhinitis (SAR) were randomized in a 2:2:1:1 ratio to receive a cumulative dose of PQ Grass as a conventional or extended pre-seasonal regimen, placebo, or placebo with MicroCrystalline Tyrosine. Gene expression analysis was an exploratory endpoint evaluated in a subgroup of 30 subjects randomly selected from the four treatment arms. Samples were collected at three time points: screening (baseline), before the start of the grass pollen season and at the end of the season. This study was funded by the manufacturer of PQ. RESULTS Transcriptome analysis demonstrated that the most significant changes in gene expression, for both treatment regimens, were at the end of the grass pollen season, with the main Th1 candidate molecules (IL-12A, IFNγ) upregulated and Th2 signature cytokines downregulated (IL-4, IL-13, IL-9) (p < .05). Canonical pathways analysis demonstrated Th1, Th2, Th17 and IL-17 as the most significantly enriched pathways based on absolute value of activation z-score (IzI score ≥ 2, p < .05). Upstream regulator analysis showed pronounced inhibition of pro-inflammatory allergic molecules IgE, IL-17A, IL-17F, IL-25 (IL-17E) (IzI score ≥ 2, FDR < 0.05) and activation of pro-tolerogenic molecules IL-12A, IL-27, IL-35 (EBI3) at the end of the grass pollen season. CONCLUSION Peripheral blood mononuclear cells transcriptome profile showed an inhibition of Th2, Th17 pro-inflammatory allergic responses and immune deviation towards Th1 responses. PQ Grass extended regimen exhibited a superior mechanistic efficacy profile in comparison with PQ conventional regimen.

Abstract
BACKGROUND The current literature indicates that intensive care (ICU) patients' sleep quality is generally poor, which is associated with serious physical and psychological consequences. AIMS AND OBJECTIVES To describe the practices nurses use to provide good-quality sleep to adult ICU patients and assess nurses' perceptions of patients' sleep quality and nurses' professional autonomy in sleep management. DESIGN A descriptive-correlational, cross-sectional study. METHODS A total of 232 ICU nurses from four hospitals in Poland were recruited. Data were collected between May and August 2019 using a previously developed questionnaire and analysed using descriptive statistics and non-parametric tests. RESULTS A total of 119 nurses took part in the study (response rate: 51%). On average, nurses rated patients' sleep quality as moderate (4.44 ± 2.23, scale 0-10). Most of the respondents (95.8%) said they did not use any sleep protocol. Various strategies to improve patients' sleep were used sporadically (2.64 ± 1.55, scale 1-5). The use of sleep quality assessment methods was positively correlated with patients' sleep quality (rho = 0.22, P = .02). Nurses' professional autonomy regarding sleep management was assessed as average (4.34 ± 2.43, scale 0-10) and was correlated with the patients' sleep quality (rho = 0.25, P < .01). Nurses who rated their autonomy in patients' sleep management more highly (rho = 0.29, P < .01) and more often influenced patients' sleep decisions (rho = 0.24, P < .01) used more methods to improve patients' sleep. CONCLUSIONS Strengthening the professional autonomy of ICU nurses and creating a reliable sleep assessment and improvement tool, which would describe strategies nurses can implement independently could increase sleep quality among ICU patients. RELEVANCE TO CLINICAL PRACTICE Addressing organizational problems, which hamper the patients' sleep management by ICU nurses could result in using more strategies to provide good-quality sleep to ICU patients. There is a need for clinical guidelines regarding patients' sleep management to help educate and guide nurses how to independently use sleep improvement methods.

Abstract
BACKGROUND Multiple sclerosis (MS) is a multifactorial autoimmune disease of the central nervous system with a heterogeneous and unpredictable course. To date there are no prognostic biomarkers even if they would be extremely useful for early patient intervention with personalized therapies. In this context, the analysis of inter-individual differences in cerebrospinal fluid (CSF) proteome may lead to the discovery of biological markers that are able to distinguish the various clinical forms at diagnosis. METHODS To this aim, a two dimensional electrophoresis (2-DE) study was carried out on individual CSF samples from 24 untreated women who underwent lumbar puncture (LP) for suspected MS. The patients were clinically monitored for 5 years and then classified according to the degree of disease aggressiveness and the disease-modifying therapies prescribed during follow up. RESULTS The hierarchical cluster analysis of 2-DE dataset revealed three protein spots which were identified by means of mass spectrometry as Apolipoprotein E (ApoE) and two isoforms of vitamin D binding protein (DBP). These three protein spots enabled us to subdivide the patients into subgroups correlated with clinical classification (MS aggressive forms identification: 80%). In particular, we observed an opposite trend of values for the two protein spots corresponding to different DBP isoforms suggesting a role of a post-translational modification rather than the total protein content in patient categorization. CONCLUSIONS These findings proved to be very interesting and innovative and may be developed as new candidate prognostic biomarkers of MS aggressiveness, if confirmed.

Abstract
Ehrlichiae are obligate intracytoplasmic Gram-negative, tick-borne bacteria belonging to the Anaplasmataceae family. Ehrlichioses are considered emerging diseases in both humans and animals. Several members of the genus Ehrlichia have been isolated and propagated in vitro. This study describes the continuous propagation of a Brazilian Ehrlichia sp. isolate in IDE8 tick cells, canine DH82 cells and bovine aorta cells. Initially, the organisms were isolated from the haemolymph of a Rhipicephalus (Boophilus) microplus tick into IDE8 cells. Infected IDE8 cells were brought from Brazil to Germany, where the organisms were continuously propagated in IDE8, DH82 and bovine aorta cells. Bovine aorta cells were infected and propagated for 3 months, corresponding to six subcultures, whereas the other two infected cell lines were kept for more than 1 year. During the cultivation period, 36 and 14 subcultures were carried out in IDE8 and DH82 cell cultures, respectively. Reinfection of IDE8 cells with organisms grown in DH82 cells was achieved. Sequence analysis made with a fragment of the 16S rRNA gene showed that this Ehrlicha sp. is closely related to Ehrlichia canis. However, the maximum likelihood phylogenetic tree shows that it falls in a separate phylogenetic clade from E. canis.

Abstract
BACKGROUND The aim of this study was to investigate the efficacy and safety profile of switching to ezetimibe/simvastatin (Eze/Simva) 10/40 mg compared with doubling the statin dose upon discharge in patients taking a statin and admitted to the hospital for the investigation of a coronary event. DESIGN This phase IV, multi-centre, randomised, open-label, active-controlled, parallel group study enrolled 424 patients (aged >/= 18 years) hospitalised for an acute coronary event and taking a stable dose of a statin (>/= 6 weeks) that could be doubled per the product label. Upon discharge from the hospital, patients were stratified by their statin dose/potency (high, medium and low) and randomised 1 : 1 to doubling of the statin dose (n = 211) or Eze/Simva 10/40 mg (n = 213) for 12 weeks. The primary efficacy variable was the absolute low-density lipoprotein cholesterol (LDL-C) value (mmol/l) at study end-point. RESULTS Mean baseline LDL-C for the two treatment groups were 2.48 and 2.31 mmol/l for the Eze/Simva and statin groups respectively. At study end-point, least squares mean LDL-C values were 1.74 mmol/l in the Eze/Simva group and 2.22 mmol/l in the statin group resulting in a significant between-group difference of -0.49 mmol/l (p </= 0.001). Eze/Simva 10/40 mg also produced significantly lower total cholesterol (-0.49 mmol/l), non-high-density lipoprotein cholesterol [(non-HDL-C); -0.53 mmol/l] and apolipoprotein B (-0.14 mmol/l) values compared with doubling the statin dose (p </= 0.001 for all). Both treatments produced similar effects on triglycerides, C-reactive protein and HDL-C; the between treatment group differences were not significant (p >/= 0.160). Significantly more patients achieved LDL-C levels < 2.5 (< 100 mg/dl; 86% vs. 72%), < 2.0 (< 77 mg/dl; 70% vs. 42%) and < 1.8 mmol/l (< 70 mg/dl; 60% vs. 31%) with Eze/Simva than statin (all p </= 0.001). Eze/Simva was generally well tolerated, with a safety profile similar to statin. There were no differences in the incidences of liver transaminases >/= 3 x upper limit of normal (ULN) or creatine kinase >/= 10 x ULN between the groups. CONCLUSIONS In patients taking a statin and admitted to the hospital for investigation of a coronary event, treatment with Eze/Simva 10/40 mg for 12 weeks produced greater improvements in lipids with a similar safety profile compared with doubling of the statin dose.

Abstract
We show that quantum dots and quantum wires are formed underneath metal electrodes deposited on a planar semiconductor heterostructure containing a quantum well. The confinement is due to the self-focusing mechanism of an electron wave packet interacting with the charge induced on the metal surface. Induced quantum wires guide the transfer of electrons along metal paths and induced quantum dots store the electrons in specific locations of the nanostructure. Induced dots and wires can be useful for devices operating on the electron spin. An application for a spin readout device is proposed.

Abstract
Preference is a composite, patient-oriented endpoint incorporating efficacy, tolerability, formulation, and convenience of medications. The objective of this study was to compare patient preference for rizatriptan 10-mg wafer vs. eletriptan 40-mg tablet for acute treatment of migraine. In this multicentre, open-label, two-period, crossover study, out-patients were randomly assigned to treat the first of two moderate to severe migraines with rizatriptan or eletriptan and the second with the alternate therapy. Patients completed diary assessments at baseline and up to 24 h after taking study medication. At the last visit, patients completed a psychometrically validated preference questionnaire. A total of 372 patients (mean age 38 years, 85% female) treated two migraine attacks, and 342 patients (92%) expressed a preference for treatment. Significantly more (P < or = 0.001) patients preferred rizatriptan 10-mg wafer [61.1%; 95% confidence interval (CI) 55.7, 66.3] to eletriptan 40-mg tablet (38.9%; 95% CI 33.7, 44.3). The most common reason given for preference of either treatment was speed of headache relief. At 2 h, 80% and 69% of patients reported that rizatriptan and eletriptan, respectively, was convenient or very convenient to take (mean convenience score 1.99 vs. 2.31, respectively; P < or = 0.001). Both triptans were well tolerated. In this head-to-head study designed to evaluate global patient preference, significantly more patients preferred the rizatriptan 10-mg wafer to the eletriptan 40-mg tablet for acute treatment of migraine. The single most important reason for preference was speed of relief, consistent with results from previous preference studies.

Abstract
Five 26-peptide analogues of the trypsin inhibitor [Pro18]CMTI-III containing Leu or Tyr in position 7 and Val or Tyr in position 27: 1 (Leu7, Tyr27), 2 (Tyr7, Val27), 3 (Tyr7, Tyr27), 4 (Leu7, Val27) and 5 (Leu7, Ala18, Tyr27) were synthesized by the solid-phase method. Analogues 1-4 displayed Ka with bovine beta-trypsin of the same order of magnitude as the wild CMTI-III inhibitor, whereas for analogue 5, this value was lower by about 3 orders of magnitude. This indicated that for the analogues with Pro (but not with Ala) in position 18, the side-chain interactions between positions 7 and 27 did not play a critical role for the stabilization of the active structure. In addition, these results also suggest that Tyr7 is involved in an additional aromatic interaction with position 41 of the enzyme.

Abstract
A PCO2 electrode working on the principle of electrical conductivity is described. The calibration curve can be linearized according to the formula G = Go + b square root PCO2. This linearity has been tested in the PCO2 range of 0.93-9.33 kPa (7--70 Torr). For the experiments electrodes are used which have conductivity values of about 50 nS and drifts of maximally 5%/h at a PCO2 of 5.33 kPa (40 Torr). The response time (T90) is about 20 s. The temperature sensitivity is 2.4 nS/1 K between 298 K-310 K. The standard error of the measurements is sigma = 0.33 nS. With these electrodes tissue PCO2 can be measured on the surface of various organs.
