Abstract
Eosinophilic granulomatosis with polyangiitis (EGPA), also known as Churg-Strauss syndrome, is a rare type of vasculitis with multisystemic involvement. Very few authors have described the anaesthesia technique in these patients. We present the first report on ambulatory surgery in a patient with EGPA. This case dispels concerns about the safety of day surgery and reports successful regional anaesthesia management in a patient with EGPA.

Abstract
Bronchiectasis is a highly complex entity that can be very challenging to investigate and manage. Patients are diverse in their aetiology, symptoms, risk of complications and outcomes. "Endotypes"- subtypes of disease with distinct biological mechanisms, has been proposed as a means of better managing bronchiectasis. This review discusses the emerging field of endotyping in bronchiectasis. We searched PubMed and Google Scholar for randomized controlled trials (RCT), observational studies, systematic reviews and meta-analysis published from inception until October 2022, using the terms: "bronchiectasis", "endotypes", "biomarkers", "microbiome" and "inflammation". Exclusion criteria included commentaries and non-English language articles as well as case reports. Duplicate articles between databases were initially identified and appropriately excluded. Studies identified suggest that it is possible to classify bronchiectasis patients into multiple endotypes deriving from their co-morbidities or underlying causes to complex infective or inflammatory endotypes. Specific biomarkers closely related to a particular endotype might be used to determine response to treatment and prognosis. The most clearly defined examples of endotypes in bronchiectasis are the underlying causes such as immunodeficiency or allergic bronchopulmonary aspergillosis where the underlying causes are clearly related to a specific treatment. The heterogeneity of bronchiectasis extends, however, far beyond aetiology and it is now possible to identify subtypes of disease based on inflammatory mechanisms such airway neutrophil extracellular traps and eosinophilia. In future biomarkers of host response and infection, including the microbiome may be useful to guide treatments and to increase the success of randomized trials. Advances in the understanding the inflammatory pathways, microbiome, and genetics in bronchiectasis are key to move towards a personalized medicine in bronchiectasis.

Abstract
Dynamical response of water exposed to x-rays is of utmost importance in a wealth of science areas. We exposed isolated water isotopologues to short x-ray pulses from a free-electron laser and detected momenta of all produced ions in coincidence. By combining experimental results and theoretical modeling, we identify significant structural dynamics with characteristic isotope effects in H2O2+, D2O2+, and HDO2+, such as asymmetric bond elongation and bond-angle opening, leading to two-body or three-body fragmentation on a timescale of a few femtoseconds. A method to disentangle the sequences of events taking place upon the consecutive absorption of two x-ray photons is described. The obtained deep look into structural properties and dynamics of dissociating water isotopologues provides essential insights into the underlying mechanisms.

Abstract
BACKGROUND This systematic review integrated the available data published in the literature on Stafne's bone defect (SBD), considering the clinical, imaging and histopathological results. MATERIAL AND METHODS An electronic search was undertaken in six databases. Eligibility criteria were: articles in English, Spanish, and Portuguese describing case reports or case series of SBD, reported up to September/2021. Risk of bias was assessed using the Joanna Briggs Institute tool. RESULTS A total of 98 articles were retrieved, involving 465 individuals with SBD and were included for quantitative analysis. Mean age was 52.78 years (range: 11-89 years), with male predilection (n=374/80.85%). Radiographs were the most frequent imagiological exams (n=298/64.09%), followed by computed tomography (n=98/21.08%). SBD was more prevalent in the posterior mandible (n=361/93.77%) as a hypodense radiolucent lesion (n=250/77.40%). Mean size was 1.58 cm (range: 0.3-.8.0 cm). Two-hundred-and-two lesions (97.37%) were unilocular and 126 (91.97%) were classified as well-defined. Clinical symptoms were reported in 73 cases, while 68 cases (93.15%) were asymptomatic. Only 34 cases (12.32%) were submitted to histopathological examination. Mean follow-up time was 26.42 ±25.39 months. CONCLUSIONS SBD is more frequent in male patients in the fifth and sixth decade of life. Classic SBD is radiographically characterized as a single, unilocular and well-defined lesion in the posterior region of the jaw with a radiolucent/hypodense appearance.

Abstract
Carbon 1s core-hole excitation of the molecular anion C2 - has been experimentally studied at high resolution by employing the photon-ion merged-beams technique at a synchrotron light source. The experimental cross section for photo-double-detachment shows a pronounced vibrational structure associated with 1 σ u → 3 σ g ${1\sigma _u \to 3\sigma _g }$ and 1 σ g → 1 π u ${1\sigma _g \to 1\pi _u }$ core excitations of the C2 - ground level and first excited level, respectively. A detailed Franck-Condon analysis reveals a strong contraction of the C2 - molecular anion by 0.2 Å upon this core photoexcitation. The associated change of the molecule's moment of inertia leads to a noticeable rotational broadening of the observed vibrational spectral features. This broadening is accounted for in the present analysis which provides the spectroscopic parameters of the C2 - 1 σ u - 1 3 σ g 2 2 Σ u + ${1\sigma _u^{ - 1} \,3\sigma _g^2 \;^2 \Sigma _u^ + }$ and 1 σ g - 1 3 σ g 2 2 Σ g + ${1\sigma _g^{ - 1} \,3\sigma _g^2 \;^2 \Sigma _g^ + }$ core-excited levels.

Abstract
We have added a multipole ion trap to the existing photon-ion spectrometer at PETRA III (PIPE). Its hybrid structure combines a ring-electrode trap with a segmented 16-pole trap. The interaction of gases and ions with extreme ultraviolet radiation from the beamline P04 is planned to be investigated with the newly installed multipole trap. The research focus lies on radiation-induced chemical reactions that take place in the interstellar medium or in the atmospheres of planets, including natural as well as man-made processes that are important in the Earth's atmosphere. In order to determine the mass-to-charge ratio of the stored ions as efficiently as possible, we are using an ion time-of-flight spectrometer. With this technique, all stored ions can be detected simultaneously. To demonstrate the possibilities of the trap setup, two experiments have been carried out: The photoionization of xenon and the ion-impact ionization of norbornadiene. This type of ion-impact ionization can, in principle, also take place in planetary atmospheres. In addition to ionization by photon or ion impact, chemical reactions of the trapped ions with neutral atoms or molecules in the gas phase have been observed. The operation of the trap enables us to simulate conditions similar to those in the ionosphere.

Abstract
Providing information to patients and, or donors at the ART clinic is essential but challenging, especially in the case of reproductive donation.
Recent developments in direct-to-consumer genetic testing combined with social media have increased the degree of difficulty. Concepts such as donor anonymity, secrecy and disclosure have to be revisited and totally re-thought as the anonymity of donors, their relatives and also of the children born through donation is no longer guaranteed.
This potentially has significant effects on everyone involved: to donors who donated under the assumption that their donation was completely anonymous, to recipients who were under the impression that they could keep donor conception a secret and to donor offspring who were unaware of their donor-assisted conception. It is also effectively retrospective affecting everyone who has, is or might participate.
Providing the correct information to donors, ART couples and donor-conceived offspring is the key, and advise for such information provision will be presented in line with the recently published ESHRE good practice recommendations for information provision for those involved in reproductive donation.

Abstract
Introduction Nitrous oxide (NO), also known as “laughing gas” is a colorless gas used as an anesthetic, a propellant in some foods, an engine performance enhancer and a recreational drug. When inhaled, it is known to provoke a rapid feeling of euphoria or excitement for a short period of time, dissociative phenomena and sometimes laughter. As its fellow anesthetic agent and NMDA-receptor antagonist, ketamine, NO is being studied for its possible therapeutic profile in treatment resistant major depression (TRMD). Objectives TRMD is a serious illness, that urges for effective alternative treatments. In that regard, we explored the recent studies conducted in these patients, using NO in different dosages when compared to placebo. Methods The authors revised the published literature about this topic, selecting relevant articles with the topic words: “Depression”, “Treatment Resistant Major Depression” and “Nitrous Oxide” in scientific data base. Results Since 2018, at least two randomized clinical trials have demonstrated that NO has considerable antidepressant effects in TRMD, when compared to placebo. Investigators noted that these positive effects where maintained at least for two weeks after a single 1-hour inhalation. In a more recent study, scientists compared different NO concentrations (25% vs. 50%) concluding that the 25% concentration had similar efficacy with a lower risk of adverse effects. Conclusions There appears to be encouraging results when treating patients with TRMD with NO in a 25% concentration. Nonetheless, there is need for further investigation, namely through studies that compare NO with other valid TRMD treatments and not only versus placebo. Disclosure No significant relationships.

Abstract
Introduction Aripiprazole (ARI) is an atypical antipsychotic drug with D2 partial agonist properties, usually prescribed to treat mood disorders (major depression or bipolar disorder) and schizophrenic disorder (schizophrenia or schizoaffective disorder). Dopamine receptor agonists, as is ARI, have been implicated in some cases of impulse-control problems, such as gambling disorder (GD), increased spending, hypersexuality and compulsive eating. Objectives Currently, it is hypothesized that aripiprazole may cause impulse-control problems because it can produce a hyperdopaminergic state in the mesolimbic pathway (reward system) through its predominant action on dopamine D3 receptors. We intend to do a non-systematic review of the scientific information regarding this subject. Methods The authors revised the published literature about this topic, selecting relevant articles, systematic reviews and case reports, with the topic words: “aripiprazol”, “gambling disorder” and “dopamine receptor” in scientific data base. Results Overall, a few cases of ARI-induced pathological gambling as well as ARI-induced hypersexuality have been reported. In one study it was verified that comorbid psychiatric and substance use disorders were common among those who have experienced GD or worsened GD after beginning ARI treatment. In another study, it was verified that the group of patients who reported this alleged side-effect were mostly young (mean age, 33.6 years), mostly men (88.2%) and most lived alone. Conclusions Attributing to dopamine agonists the only factor that can explain the onset of GD is simplistic and dangerous. Many other potential risk factors, including individual vulnerability factors (temperament, genetics) as well as environmental factors, must be considered. Disclosure No significant relationships.

Introduction
Pulmonary embolism (PE) is associated with morbidity and mortality. Immediate recognition of this condition is critical to commencement of early and appropriate therapy which could be lifesaving. Particularly in patients with suspected PE in which computed tomography pulmonary angiography (CTPA) is not promptly available or is contra-indicated, an electrocardiographic (ECG) score could serve as a ubiquitously available test to raise suspicion of PE. This study aimed to evaluate the diagnostic value of an ECG score for PE diagnosis.
Methods
Retrospective study of consecutive patients who performed CTPA in Emergency Department due to PE suspicion. All ECG were scored according to the previous published Daniel’s ECG score, by an investigator blinded for the CTPA result.
Results
The most common ECG findings in patients with PE were incomplete right-brand bock (48%), T wave inversion in DIII (48%), sinus tachycardia (41%) and Q wave in DII (31%). The S1Q3T3 sign was documented in 20% of patients.
The ECG score was significantly higher in patients with PE compared to those without PE (5.06 vs 3.70, p=0.005). ECG score showed moderate accuracy to detect PE (AUC: 0.60; 95%CI: 0.53-0.67; p=0.004), but it is of a particular value because of very high specificity: an ECG score > 12 identified PE with a specificity of 96% (95% CI 91.93 – 98.38).
The ECG score significantly increased the diagnostic accuracy of the diagnostic algorithm based on pretest clinical probability evaluated by Wells score combined with D-Dimer measurement (Wells & DD). In comparison to patients in which clinical pretest probability combined with D-dimer measurement considers PE excluded (Wells & ECG -), PE was 6.3 times more frequent in patients with Wells & DD +/ECG- (95% 2.7- 14.5) and 14.6 times more prevalent in the ones with Wells & DD +/ECG+ (95%CI: 4.1-51.3; p<0.001) – Figure 1.
Conclusion
In patients with clininal suspition of PE, na ECG score (Daniel’s score) >12 predicts PE with 96% specificity and could be used to increase the suspicion and define therapeutic strategy in patients in whom CTPA could not be immediately performed or is contra-indicated.

Abstract
OBJECTIVE To identify predictors of immune-related adverse events (IRAEs) in patients with non-small cell lung cancer (NSCLC) treated with immune checkpoint inhibitors (ICIs). Assess associations between outcomes and the development of IRAEs. METHODS Retrospective analysis of patients with NSCLC treated with ICIs between 2016 and 2020 in the Pulmonology Department of our hospital. Patients with and without IRAEs were compared. A logistic regression analysis was performed to determine predictors of IRAEs. Progression-free survival (PFS) and overall survival (OS) curves were calculated using the Kaplan-Meier method, and the long-rank test was used to assess survival differences between groups. Univariate and multivariate Cox proportional-hazards regression models were used to identify factors associated with PFS and OS. The value considered statistically significant was p≤0.05. RESULTS A total of 184 patients (77.7% men, mean age 66.9±9.5 years) treated with ICIs were analyzed. During follow-up, 49 (26.6%) patients developed IRAEs and 149 (81.0%) died. According to the multivariate logistic regression analysis, treatment with statins (OR:3.15; p = 0.007), previous systemic corticosteroid therapy (OR:3.99; p = 0.001), disease controlled as response to ICI (OR:5.93; p < 0.001) and higher hemoglobin values (OR:1.28; p = 0.040) were independent predictors for the development of IRAEs. Patients who developed IRAEs had significantly longer medians of PFS (41.0 vs 9.0 weeks, p < 0.001) and OS (89.0 vs 28.0 weeks; p < 0.001). CONCLUSIONS Patients treated with statins, pre-ICI systemic corticosteroids, higher baseline hemoglobin value and controlled disease as initial response to ICI had a higher risk of developing IRAEs. The development of IRAEs was associated with better outcomes.

Abstract
Abstract
Introduction
Aortic atherosclerotic plaques (AAPs) are one of the major causes of spontaneous and iatrogenic stroke and peripheral emboli, carrying an high morbidity and mortality. Transoesophageal echocardiography (TOE) plays a key rule on detecting AAP. The therapeutic approach of this patients (pts) is not well stablished.
Purpose
To evaluate the impact of anticoagulation (ACO) therapy on major events in asymptomatic pts with AAP detected in TOE.
Methods
Single-center retrospective study of consecutive patients submitted to TOE between 2010 and 2019 with documentation of AAP. Plaques were described as complex (1) >4mm, (2) ulcerated and (3) mobile thrombi. The plaque location was also documented. We consulted pts data charts for clinical characterization and events recording during the follow up. Major events were defined as stroke, bleeding, hospital admissions (either cardiovascular (CV) and non-CV) and death. Statistical analysis was performed using Cox regression and Chi-square tests.
Results
We enrolled 177 pts with a mean age of 70±10.5 years, 63.8% males, 31.1% diabetic, 73.4% hypertensive, 54.2% with dyslipidaemia, 62.7% obese, 25.4% with peripheral arterial disease, 25.9% with previous stroke and 55.4% with supraventricular arrhythmia. Most of pts had plaques >4mm (80.8%), mobile thrombi in 11.9% and ulcerated plaques in 7.3%; most of the plaques were located in proximal descending aorta (50.3%) and aortic cross (38.4%). Regarding baseline therapy, 52% were under ACO and 50.3% under statin. The main indication of ACO was atrial fibrillation (45.8%).
During follow up (mean time: 1613±1255 days), 61.5% pts died (10.7% from CV causes, 13% with unknown cause), 17.5% had a stroke, 5.7% had other embolic event (lower limbs emboli, unilateral amaurosis and ischemic colitis). Bleeding occurred in 18.3% pts; 47% pts were hospitalized (28.3% from CV cause).
Adjusting for age and comorbidities, there were no significant differences between the group with and without ACO. ACO therapy prevented death from any cause, being also an independent predictor (p=0.08, OR 0.489, IC 95% 0.288–0.831) when adjusted for comorbidities and age. ACO was associated with bleeding events (p=0.003), but not with stroke or hospitalization from any cause (p=NS).
Conclusion
In this subset of pts, ACO therapy prevented death from any cause in pts with AAP. This may have therapeutic implications when approaching this pts, although larger studies to confirm these results are needed.

Abstract
Abstract
Study question
What sexual strategies do individuals TTC with different fertility status use?; What are the predictors of sexual dysfunction(SD) and frequency of intercourse(IF) when TTC? Summary answer: TTC strategies with no evidence of effectiveness are the most used. Poor marital quality predicted SD, and female SD was a significant predictor of IF.
What is known already
It is well known that couples TTC have low fecundity knowledge. Previous evidence showed that after 12 months the frequency of intercourse decreases. After seeing a fertility specialist couples report a feeling of waiting time by attempting natural conception, which can be associated to evidence of an overestimation and excessive confidence in the success of fertility treatments. Existing guidelines recommend intercourse every other day, but no comparative studies exist up to date on what sexual strategies are used in different fertility status and what are the predictors of sexual frequency and sexual dysfunction when trying to conceive.
Study design, size, duration
This study is part of a randomized controlled trial on the effects of timed intercourse in psychosocial outcomes. Data was collected between July 2016 and November 2019 via an advertising strategy and obstetrics/gynecology centers. Inclusion criteria were: i) adult in a marital/cohabitation heterosexual relationship >1 year; ii) not knowing of any condition that can prevent pregnancy; iii) being actively TTC; iv) female age >22<42 years old; v) no previous children. Measurements were carried out online.
Participants/materials, setting, methods
Our final sample had 399 subjects (252 women). Participants rated the use of the following strategies: intercourse every other day (EOD), fertile week (FW), basal temperature, cervical mucus monitoring (CMM), ovulation predictor kits (OPK), and keeping legs elevated afterwards (EL). We also accessed psychological adjustment, relationship quality, SD and IF. Comparisons between groups were made by analysis of variance (ANOVA) and Chi-square tests, and logistic regression was used to determine predictors of SD and IF.
Main results and the role of chance
Participants were highly educated (72,8%), in the relationship for 9 years (±5.2), cohabitating for 5 (±3.6), and TTC for 2,5 years (range 0–16). Women were 33 years old (±4.4) and men 36 (±5.5). Regarding fertility status, 22.6% of participants were TTC <12 months, 22.8% >12 months but not diagnosed, 23.6% had a diagnosis but no treatment, and 31.1% had ART. The most reported female strategy in all groups was EL, and the most never used was OPK. Differences were found in EOD, with significantly more women TTC <12 months that never used it, and more women with previous ART using it. Women who had ART are the ones who more frequently use FW and CMM comparing to other women (P>.05). In all groups, the majority reported IF once or twice/week. SD was found in 17.5% of women and 10,9% of men. Age (OR 0.91, 95%CI 0.85–0.97) and SD (OR 2.47, 95%CI 1.02–6.02) were the only predictors of low IF for women, with no significant findings for men. Poor relationship quality increased the risk of SD for both men (OR 0.11, 95%CI 0.03–0.40) and women (OR 0.46, 95%CI 0.03–0.40), and depression increased the risk of female SD (OR 1.24, 95%CI 1.06–0.46).
Limitations, reasons for caution
The cross-sectional nature of this study does not allow causal relationships to be determined. Further cohort studies allowing to assess differences as couples cross different fertility status are warranted. There are important predictors of SD that were not considered, specifically the comorbidity of diseases and pain.
Wider implications of the findings: Findings indicate that individuals TTC are misinformed, and that those using evidence-based sexual strategies are fertility patients. SD should be screened in patients TTC given that it might be an important predictor of IF. Couples might benefit from counselling to improve marital quality and consequently sexual functioning.

Abstract
Introduction Discontinuity in child and adolescent mental health services (CAMHS) and adult mental health services (AMHS) constitutes an important challenge in mental health care. In the last decade, efforts have been made to better define the transitioning population and build consensual models for CAMHS-AMHS’ transition. Objectives We aim to present our protocol and transition consultation results on the scope of published literature. Methods Description of protocol and casuistic of 18 months’ transition consultation at Centro Hospitalar Barreiro-Montijo. The literature found on PubMed was published from 2008 to 2020 and was reviewed using the keywords: transition, CAMHS, AMHS, adolescent, mental health service, young people. Articles with full text available written in English and French were selected. The included clinical studies focused on populations with neurodevelopmental disorders, psychotic disorders, non-suicidal self-harm and suicidal attempts. Results Forty-four articles were included, published from 2008 to 2020. 4 articles were excluded on basis of language and diagnosis criteria (eating disorders). Twelve were reviews, 24 were clinical studies and 4 were opinion articles. There are cultural and referral issues that explain the loss of patients in this transition gap. Individuals with history of severe mental illness were more frequently referred than those with neurodevelopmental disorders. Optimal transition is defined as adequate transition planning with a flexible age cut-off and continuity of care following transition. Conclusions For the vast majority of service users, transition from CAMHS to AMHS is poorly planned, executed and experienced. Improving transition models is essential to the patients autonomy’ promotion and a stronger adult mental health.

Abstract
IntroductionBipolar disorder (BD) is frequently underdiagnosed and due to poor screening, the average time between onset of symptoms and diagnosis is more than 7-years (Mantere et al., 2004). Improper diagnosis has serious consequences in intervention (Ghaemi et al., 2001), and previous assessment instruments are now considered insufficient to detect intervention changes, and to provide a more functional and integrated view of BD.ObjectivesOur study aims to develop a new DSM-5 based Clinical Interview for Bipolar Disorder (CIBD), providing criteria to diagnose BD, but also the individual’s perceptions dealing with BD symptoms. This interview follows the same structure of CIPD (Martins et al., 2015), which has shown acceptability by the participants and experts.MethodsCIBD was developed by a multidisciplinary team considering the DSM-5 criteria for Bipolar Disorders. There was a thorough research regarding assessment and evaluation of BD, and several suggestions from an international task force of specialist working with BD patients were considered, when writing the questions for the interview. A detailed description of CIBD development is presented. The authors of the interview have extended experience in the management and assessment of BD patients, and CIBD is now being assessed by a wider non-related panel, regarding pertinence and clarity.ResultsPreliminary assessment and qualitative feedback from participants that were interviewed is shown, with an overall positive feedback.ConclusionsCIBD assesses both the diagnosis/presence of mood episodes (hypo/mania, and depressive) and symptoms’ psychosocial correlates. CIBD detects subtle changes caused by intervention adding a much needed recovery focused perspective.DisclosureNo significant relationships.

Abstract
Introduction Coronavirus disease (COVID-19) has been associated with the development mental and behavioural symptoms and psychiatric disorders. This association is stronger in severe cases of the disease and in those needing inpatient treatment, particularly in intensive care units (ICU). Objectives To determine the incidence of psychiatric disorders in a Portuguese hospital-based sample of patients with COVID-19. To describe relevant demographic and clinical data. Methods We reviewed all COVID-19 inpatients assessed by liaison psychiatry at our hospital between April and September 2020. Patients admitted due to a psychiatric disorder were excluded from the analysis. We reviewed medical records and retrieved relevant clinical data. ICD-10 was used to classify diagnoses. Results We identified 36 cases with a mean age of 62.64 years-old (SD 19.23). The most common disorder was delirium, which occurred in 41.7% of our sample (15 patients), followed by adjustment disorder (22.2%, n=8), and depressive episode (16.7%, n=8). Most patients had no personal (61.1%, n=22) nor family (75%, n=27) history of a psychiatric disorder. Mean length of admission was 36.89 days (SD 28.91). Seventeen cases (47.22%) had at least one risk factor for severe COVID-19 disease and 14 (38.89%) were admitted at some point to the ICU. Conclusions In our sample, delirium was the main cause for mental or behavioural symptoms in COVID-19 patients. However, we observed a wide array of presentations in our center. A larger sample would allow to better characterize this often-overlooked symptoms and identify risk factors to psychiatric syndromes. Disclosure No significant relationships.

Abstract
The F 1s core level photoionization of the ionic molecular radical HF+ has been studied using the photon-ion merged-beams technique at a synchrotron radiation source. Upon analyzing kinetic energy release (KER) dependent photoion yield spectra, complex ultrafast dissociation dynamics of the F 1s core hole excited σ* state can be revealed. By means of configuration-interaction electronic structure calculations of the excited molecular potential energy curves, this complex process can be attributed to a spin-dependent dissociation of the excited σ* biradical state.

Abstract
AbstractSchool classrooms within the EU are multilingual learning environments. The diversity of pupils in classrooms raises significant challenges for teachers, but to date, there are no data from large-scale surveys that compare views within and across European countries. A bespoke questionnaire was designed to examine views of current classroom learning environments with respect to the multilingualism. The questionnaire was piloted and subsequently completed by 2792 teachers across different European countries. Eleven countries provided sufficient data for analyses. Results from structural equation modelling showed that teachers’ attitudes could be reliably measured across Europe with the use of carefully devised questionnaire, whose loading and factor structure remained invariant across countries. Teachers’ views about multilingualism were most challenged by the numbers of children in their classes, not the percentage of multilingual pupils in the class. Countries differed in how they perceived multilingualism, with their differences leading to distinctive country clusters. Gender and education level (elementary vs. secondary) differences were also observed irrespective of country. These findings enhance our understanding of the role that the characteristics of teachers and their classrooms play in a multilingual setting across diverse European settings. The practical relevance of the results and new opportunities for teacher training are discussed.

Abstract
Abstract It is a fact that the regions that cultivate the most maize crop do not have fully adequate technologies to measure productivity losses caused by irregularities in water availability. The objective of this study was to evaluate the physiological characteristics of maize hybrids tolerant (DKB 390) and sensitive (BRS 1030) to drought, at V5 growth stage and under water restriction, in order to understand the mechanisms involved in the induction of tolerance to drought by chitosan in contrasting maize genotypes. Plants were cultivated in pots at a greenhouse, and chitosan 100 ppm was applied by leaf spraying. The water restriction was imposed for 10 days and then leaf gaseous exchange and chlorophyll fluorescence were evaluated. The tolerant hybrid (DKB 390) showed higher photosynthesis, stomatal conductance, carboxylation efficiency, electron transport rate, and non-photochemical quenching when chitosan was used. Plants from tolerant genotype treated with chitosan were more tolerant to water stress because there were more responsive to the biopolymer.

Abstract
Background:Autoimmune disease (AID) has been associated with increased risk of influenza and influenza-like illness (ILI) and its worse clinical outcomes complications.Objectives:We aimed to assess the influence and difference of several immunosuppressive (IS) treatments in the incidence of ILI, including glucocorticoids (GC), classic DMARDs and biologic DMARDs.Methods:We conducted a cross-sectional study in two autoimmune clinics. Patients were invited to answer a survey reporting ILI symptoms between October 2017 and March 2018. ILI definition was considered according to the European Center for Disease Control. Data regarding current IS, diagnostic, disease activity, comorbidities, and vaccination coverage were collected from electronic registry. Patients with history of cancer, HIV, IGIV treatment, or lack of information were excluded. Univariate and multivariate logistic regression analysis were used to access predictors of ILI.Results:We included 109 patients, with mean age 51 years and 81% female gender. The majority of patients had autoimmune arthropathy (n=54) or a connective tissue disease (n=44). Active disease was present in in 39% of patients. IS treatment was: GC 31%, classic DMARD 44%, biologic DMARD 28%. Vaccine coverage was 51%. Overall 41% reported ILI. We did not find any association between studied variables and ILI, including univariate and multivariate analysis. Univariate odds ratio calculation for IS treatment were: GC [OR 1,68 IC 0,7-3,8], classic DMARD [OR 1,03 IC 0,5-2,2], and biologic DMARD [OR 0,86 IC 0,4-2,0]. Comorbidity of pulmonary disease (n=8) may contribute to higher risk to ILI [OR 2,76 IC 0,8-10,0].Conclusion:There was no difference in risk of ILI within different IS treatment regimens, although GC may increase the risk. The study is limited by the subjectivity of the ILI survey and the small size of the sample. The stratification of influenza risk will help in designing better vaccine coverage strategies in this population.References:[1]Nakafero G, Grainge MJ, Myles PR, Mallen CD, Zhang W, Doherty M, Nguyen-Van-Tam JS, Abhishek A.

Abstract
We report on new measurements of m-fold photodetachment (m=2-5) of carbon anions via K-shell excitation and ionization. The experiments were carried out employing the photon-ion merged-beams technique at a synchrotron light source. While previous measurements were restricted to double detachment (m=2) and to just the lowest-energy K-shell resonance at about 282 eV, our absolute experimental m-fold detachment cross sections at photon energies of up to 1000 eV exhibit a wealth of new thresholds and resonances. We tentatively identify these features with the aid of detailed atomic-structure calculations. In particular, we find unambiguous evidence for fivefold detachment via double K-hole production.

Abstract
The need to overcome logistic and ethical limitations of in vivo nanotoxicity evaluation in marine organisms is essential, mostly when dealing with fish. It is well established that medium/solvent conditions affect dispersion and agglomeration of nanoparticles (NPs), which represents a constraint towards a solid and realistic toxicity appraisal. In this way the pros and cons of an ex vivo approach, using a simplified exposure medium (seawater) and addressing gills histopathology, were explored. The nanotoxic potential of environmentally realistic concentrations of titanium dioxide NPs (TiO2 NPs) was also assessed, disclosing the morpho-functional effects on the gills and the possible uptake/elimination processes. Excised gills of the Senegalese sole (Solea senegalensis) were directly exposed in artificial seawater to 20 and 200 μg L-1 TiO2 NPs, for 2 h and 4 h. Semi-quantitative and quantitative histological analyses were applied. The normal morphology of the gill's epithelia was only slightly altered in the control, reflecting protective mechanisms against the artificiality of the experimental conditions, which, together with the absence of differences in the global histopathological index (Ih), corroborated that the gill's morpho-functional features were not compromised, thereby validating the proposed ex vivo approach. TiO2 NPs induced moderate severity and dissemination of histopathological lesions. After 2 h, a series of compensatory mechanisms occurred in NP treatments, implying an efficient response of the innate defense system (increasing number of goblet cells) and effective osmoregulatory ability (chloride cells proliferation). After 4 h, gills revealed signs of recovery (normalization of the number of chloride and goblet cells; similar Ih), highlighting the tissue viability and effective elimination and/or neutralization of NPs. The uptake of the TiO2 NPs seemed to be favored by the higher particle sizes. Overall, the proposed approach emerged as a high-throughput, reliable, accurate and ethically commendable methodology for nanotoxicity assessment in marine fish.

Abstract
Background We aim to evaluate the presence of histological artefacts in the surgical margins of human oral fibro-epithelial hyperplasias excised with lasers of different wavelengths, and also electrosurgical scalpel and cold scalpel. Moreover, we aim to determine if some of these instruments could impair the normal histological diagnosis of these lesions. Material and Methods We included 130 consecutive surgical samples of 80 females and 50 males (mean age of 53.82±16.55) with a histological diagnosis of an oral benign fibrous-epithelial hyperplasias. The samples were categorized into 6 groups according to the type of instrument used: CO2 laser group, diode laser group, Er:YAG laser group, Nd:YAG laser group, electrosurgical scalpel group and cold scalpel group. Histological instrument-induced changes were microscopic evaluated and related with clinical and pathological variables. Results The instrument with highest tissue damage extension (TDE) was the electrosurgical scalpel (1002.2µm±434.92), followed by diode laser (913.73 µm±322.45), Nd:YAG (899.83µm±327.75), CO2 laser (538.37µm±170.50), Er:YAG laser (166.47µm±123.85), and at last with fewer alterations the cold scalpel group (2.36µm±7.27) (P< 0.001). The most regular incision was observed in CO2 laser group, followed by Er:YAG laser, Nd:YAG laser, electrosurgical scalpel and diode laser group with the less regular incision using cold scalpel as comparison (P< 0.001). A correlation was found between the incision score and TDE (P< 0.001). Regarding histological diagnosis, no case showed any limitation of diagnosis related with the use of any instrument evaluated. Conclusions Our results suggest that lasers can be used for the excision of oral benign fibrous-epithelial hyperplasias, without hispathological diagnosis limitations, as long as the physical properties of each laser are known and respected. Er:YAG laser have shown to be a laser with few tissue damage extension and with good incision regularity, been a possible instrument of choice for the surgical removal of these lesions. Key words:CO2 laser, diode laser, Er:YAG laser, Nd:YAG laser, oral mucosa.

Abstract
Hobi-like viruses (HobiPeV) comprise a novel, recently classified species of bovine pestiviruses, originally identified in commercial fetal bovine serum of Brazilian origin and, subsequently, isolated from diseased animals in several countries. Although frequently isolated from clinical cases, most HobiPeV isolates failed to reproduce overt disease in cattle upon experimental inoculation. Herein, we describe the outcome of experimental infection of four to six months-old seronegative calves with two Brazilian HobiPeV isolates. Calves inoculated intranasally with isolate SV478/07 developed viremia between days 2 and 9 post-inoculation (pi) and shed virus in nasal secretions up to day 11pi. These animals presented hyperthermia (day 7 to 10-11 pi) and lymphopenia from days 4 to 8pi. Clinically, all four calves developed varied degrees of apathy, anorexia, mild to moderate respiratory signs (nasal secretion, hyperemia), ocular discharge and pasty diarrhea in the days following virus inoculation. In contrast, calves inoculated with isolate SV757/15 presented only hyperthermia (days 3 to 10-11 pi) and lymphopenia (days 4-8 pi), without other apparent clinical signs. In these animals, viremia was detected up to day 9 pi and virus shedding in nasal secretions lasted up to day 12-14 pi. Both groups seroconverted to the inoculated viruses, developing virus neutralizing (VN) titers from 320 to 5120 at day 28pi. These results extend previous findings that experimental infections of calves with HobiPeV are predominantly mild, yet they also indicate that field isolates may differ in their ability to cause disease in susceptible animals.
