Abstract
Introduction Personal and environmental factors may contribute to psychological distress in medical students. As a result, they are more susceptible to suicidal ideation, a serious public health problem. Objectives Estimate the prevalence and recognize associated factors of Suicide Ideation and Suicide Attempt among medical students at the Federal University of Sergipe, Brazil. Methods A cross-sectional study was performed with randomly selected students between April and June 2019. A structured online questionnaire about sociodemographic characteristics, educational process, and the current psych emotional experiences, besides Beck Scale for Suicide Ideation (BSI), which detects the presence of suicidal ideation, were applied. Statistical evaluation was performed with descriptive analysis and logistic regression for the evaluation of multiple variables. Results The study included 133 students, with an average age of 22.9±3.5 and 51,9% were male. Among this sample, 27,1% had suicidal ideation. The frequency is higher in those students who family income <10 minimum wages (OR=3.47) and who were not satisfied with the course (OR=3.52). Furthermore, the frequency of suicide attempt was 15.8%. It was higher among those who claimed to use a doctor-prescribed psychopharmaceutical (OR=10.46) and who lost some discipline in the course (OR=8.17). Ideation and attempt were significantly associated (p<0.001). Conclusions Frequency of suicidal ideation was high, associated with dissatisfaction related to the educational process, as well as lower family income. History of attempted suicide was also frequent and associated with ideation. Intervention and prevention measures are required.

Abstract
IntroductionCommon Mental Disorders (CMD) are minor manifestations of depressive, anxious or somatoform symptoms, which do not fit the diagnostic criteria of the International Code of Diseases (ICD). In medical students, this panorama can generate even more repercussions given the complexity of the medical education process.ObjectivesEstimate the prevalence and recognize associated factors of CMD among medical at the Federal University of Sergipe, Brazil.MethodsA cross-sectional study was performed with randomly selected students between April and June 2019. The Self Report Questionnaire (SRQ-20) were used, along with a questionnaire about socioeconomic and demographic characteristics, personal aspects and educational process, prepared by the authors and previously tested in a pilot study. Statistical evaluation of multiple variables was performed through backward stepwise logistic regression analysis.ResultsThe study included 80 students, equivalent to 22.59% of the total population of the studied Campus. There was an age average of 23.2 years (± 4.12), mostly female (52.5%) and single individuals (35%). The prevalence of CMD was 50% and an association was observed with the following factors: feeling of dissatisfaction with the course (p = 0.034); consider their own academic performance poor or regular (p = 0.12); lack of physical activity (p = 0.043); being anxious when not using a cell phone (p = 0.007); and the retraction pattern in the face of conflict situations in their interpersonal relationships (p = 0.025).ConclusionsResults suggest a high prevalence of CDM, associated mainly with the personal perspective about the educational process and personal habits.

Abstract
Introduction Medical students are exposed to many stressors which may contribute to the onset of Burnout Syndrome (BS). It consists of a triad of emotional exhaustion, cynicism and low professional efficacy. As a result, BS may reduce academic performance, quality of life and damage future professional life. Objectives Estimate the prevalence and recognize associated factors of BS among medical students from two different medical schools form the same Brazilian Public University with different teaching models: School 1, with a traditional model, and School 2, with Problem-Based Learning model. Methods A cross-sectional study was performed with randomly selected students between April and June 2019. A structured questionnaire on socio-demographic characteristics and the educational process in addition to The Maslach Burnout Inventory/Student Survey (MBI-SS) were used. Statistical evaluation of multiple variables was performed through backward stepwise logistic regression analysis. Results Study included 213 students, with an average age of 23±3.77, 50,2% were male and 62,5% belong to School 1. Among this sample, 21,6% of the students fit tridimensional criteria for BS. Burnout levels were higher in those people who rarely get emotional support they need in the course (OR=3,98, CI 95%, 1,75-9,06), who considered abandoning the course (OR= 2,88, CI 95% 1,29-6,43) and who consider their academic performance regular or weak (OR= 12,1, CI 95%, 4-36,5). Conclusions Results suggest a high prevalence of BS with factors associated with the psychosocial and educational sphere of medical students. In our research, the teaching model was not a factor associated with BS.

Abstract
Summary Background. Severe cutaneous adverse reactions (SCAR) are potentially fatal reactions. Genetic predisposition is involved in their pathogenesis related to drugs and ethnicities, however in a mixed population these relationships are still unknown. The aim of this study was to describe phenotypes, suspect drugs and HLA-alleles related to SCAR, identified by a systematized approach in a Brazilian case series. Methods. Patients who were diagnosed with SCAR between March 2011 and July 2019 at our university hospital were included. European Network for Drug Allergy (ENDA) questionnaire was used to collect clinical and laboratory data and algorithms for assessment of drug causality were applied. Socio-demographic variables included age, gender and skin color/ethnicity. Drug patch tests (DPT) and HLA-A, -B, -DRB1 typing were carried out. Results. A total of 74 patients were included: 36 (48.64%) with SJS/TEN, 32 (43.24%) DRESS/DIHS, 3 (4.05%) AGEP, 2 (2.70%) overlap(DRESS/SJS and DRESS/AGEP) and 1 (1.35%) GBFDE. The median age was31.5 years (IQR = 14-52.25), most were female (n = 44/59.46%) and brown (n = 38/51.35%). Anticonvulsants (n = 32/43.24%) were the largest group involved and antibiotics (n = 26/35.13%) were the second most common. Two patients with DRESS died during the acute phase. Positive DPT were shown only in anticonvulsant associated DRESS. HLA related to abacavir, allopurinol and carbamazepine were identified. Conclusions. A systematized approach allowed the phenotypic characterization of SCAR. The HLA-A*31:01, B*57:01 and B*58:01 alleles were identified, reinforcing the causality in SCAR by CBZ, ABC and ALLO in the Brazilian population.

Abstract
PURPOSE To assess the predictive value for functional recovery of Ganglion Cell Complex Layer (GCC) and Retinal Nerve Fiber Layer (RNFL) measurements obtained by Optical Coherence Tomography (OCT) in patients undergoing chiasmal decompression and to define potential OCT thresholds for visual recovery. METHODS We measured preoperative GCC and RNFL thickness in patients with a sellar and/or perisellar tumor compressing the optic chiasm. Visual recovery was defined as recovery of mean deviation (MD) and pattern standard deviation (PSD) using Humphrey visual field testing after 12 successful decompressions (24 eyes). Receiver operating characteristic curve (ROC) analysis was used to identify the best thresholds. RESULTS Robust global and focal OCT thresholds were found. Superior GCC≥63μm had the best functional prognostic value (AUC=1) for visual improvement. Mean GCC ≥ 67μm and mean RNFL≥75μm also had excellent predictive values (AUC>0.9). CONCLUSION In this preliminary study, significant preoperative OCT thresholds for early visual recovery after chiasmal decompression were identified, mainly regarding GCC measurements. Further studies on larger cohorts with closely scheduled follow-up could refine our results.

Abstract
AIM As a person ages, the risk of falls increases, which affects quality of life and represents a financial burden to health- and social-systems, and a greater morbidity and mortality risk. Falls lead to decreased social contact, anxiety, long-term physical disability, severe dependency and hospitalizations. Currently, few studies address this phenomenon using a uniform methodology; therefore, this study aims to explore the prevalence of falls and associated-variables in older adults across Europe. METHODS In this cross-sectional analysis, we used data from Wave 6 of SHARE. The prevalence of falls was assessed through the answer "falling down" to the question "For the past six months at least, have you been bothered by any of the health conditions on this card?". Multilevel logistic regression was used, using falls as a dependent variable. Multilevel univariable logistic regression models were made to identify potential associated factors. RESULTS From the 41,098 participants, 56.3% were female, and the average age was of 70.0 ± 8.9 years. The prevalence of falls was 8.2% (CI 8.0% to 8.4%), being higher in women (10.1% vs. 5.8%) and increasing with age. Age, female gender, being frail or pre-frail, higher scores on the EURO-D scale, polypharmacy and fear of falling were found to be significantly associated with falls. CONCLUSIONS We found that falls are prevalent in the European community-dwelling population, with variations between countries. As a public health priority, identification of the variables associated with falls is important in order to identify/monitor the risk in older groups and develop tailored and cost-effective interventions for falls prevention.

Abstract
Background The analysis of mobile health (mHealth) data has generated innovative insights into improving allergic rhinitis control, but additive information is needed. A cross-sectional real-world observational study was undertaken in 17 European countries during and outside the estimated pollen season. The aim was to collect novel information including the phenotypic characteristics of the users. Methods The Allergy Diary–MASK-air–mobile phone app, freely available via Google Play and App, was used to collect the data of daily visual analogue scales (VASs) for overall allergic symptoms and medication use. Fluticasone Furoate (FF), Mometasone Furoate (MF), Azelastine Fluticasone Proprionate combination (MPAzeFlu) and eight oral H1-antihistamines were studied. Phenotypic characteristics were recorded at entry. The ARIA severity score was derived from entry data. This was an a priori planned analysis. Results 9037 users filled in 70,286 days of VAS in 2016, 2017 and 2018. The ARIA severity score was lower outside than during the pollen season. Severity was similar for all treatment groups during the pollen season, and lower in the MPAzeFlu group outside the pollen season. Days with MPAzeFlu had lower VAS levels and a higher frequency of monotherapy than the other treatments during the season. Outside the season, days with MPAzeFlu also had a higher frequency of monotherapy. The number of reported days was significantly higher with MPAzeFlu during and outside the season than with MF, FF or oral H1-antihistamines. Conclusions This study shows that the overall efficacy of treatments is similar during and outside the pollen season and indicates that medications are similarly effective during the year.

Abstract
AIMS To evaluate how common radiation therapy techniques perform in the setting of the new European Society for Radiotherapy and Oncology-Advisory Committee in Radiation Oncology Practice (ESTRO-ACROP) delineation recommendations for immediate breast reconstruction (IBR). MATERIALS AND METHODS Seven Danish radiation therapy centres and six international European centres participated in this project. Two breast cancer cases (one left-sided and one right-sided) with a retropectoral implant were chosen for radiation therapy planning using deep-inspiration breath-hold. Target volumes were delineated according to ESTRO-ACROP delineation recommendations. The centres were asked to plan the cases using any radiation therapy technique according to the Danish Breast Cancer Group plan objectives. RESULTS In total, 35 treatment plans were collected. Half of the submitted plans, for both the left-sided and the right-sided case, used the field-in-field (FiF) technique (nine for each), a quarter used volumetric arc radiation therapy (VMAT; five for right-sided, four for left-sided) and the remaining quarter was a mix of inverse intensity-modulated radiation therapy (IMRT), helicoidal therapy and hybrid (combined open fields and VMAT) techniques. Mean clinical target volume doses were in the range 99-102% of the prescribed dose. The median FiF mean heart dose (MHD) for right-sided radiation therapy was 1 Gy (range 0.8-3.7) and 5.2 Gy for left-sided radiation therapy (range 2.2-6.5). For right-sided radiation therapy, the median VMAT MHD was 3.42 Gy, for IMRT was 2.3 Gy and for helicoidal therapy was 5.1 Gy. For left-sided radiation therapy, the median VMAT MHD was 6.3 Gy, for IMRT was 7.8 Gy and for helicoidal therapy was 7.3 Gy. CONCLUSIONS Different radiation therapy techniques could be used to plan radiation therapy in the setting of IBR. FiF provided good coverage with acceptable organ at risk doses. The best dose distribution results as a trade-off between the objectives of target volume coverage and high-dose organ at risk inclusion. The radiation therapy technique affects the interplay between these objectives.

Abstract
Background Malaria can be transmitted by blood transfusion through donations collected from asymptomatic donors. Transfusion-transmitted malaria (TTM) poses a great risk to blood services worldwide. A good screening tool for Plasmodium spp. detection in blood banks must have a high sensitivity for prevention of TTM. However, in Brazilian blood banks, screening for malaria still relies on microscopy. Methods In Brazil, screening for human immunodeficiency virus type 1 (HIV), RNA/DNA for hepatitis C (HCV) and hepatitis B (HBV) viruses is mandatory for every blood donation and uses nucleic acid amplification testing (NAT). The aim of this study was to evaluate the inclusion of an assay for malaria to identify Plasmodium sp. from total nucleic acid (TNA; DNA/RNA) by targeting the 18S rRNA gene of the parasite. Results Considering the limitations of microscopy and the wide availability of the Brazilian NAT platform in the screening of blood units for HIV, HCV, and HBV, a molecular diagnostic tool was validated for detection of Plasmodium sp. in blood banks; a pilot study showed that using this novel NAT assay could reduce the risk of TTM. Conclusion The prototype HIV/HCV/HBV/malaria NAT assay was effective in detecting infected candidate donors and has good prospects to be applied in routine screening for preventing TTM.

Abstract
BACKGROUND The incidence of breech presentation in single pregnancies at term is between three to 5 %. In order to support eligible women in their choice of mode of delivery, a dedicated breech clinic with a care pathway was developed in December 2015 in a tertiary referral centre in Brussels. The primary objective of this study was to evaluate the vaginal birth rate before and after the introduction of a dedicated breech clinic. The secondary objective was to compare the early neonatal outcomes before and after the breech clinic was introduced. METHODS This was a single centre retrospective and prospective study. The inclusion criteria were term (from 37 weeks), singleton fetus and breech presentation at delivery. The exclusion criteria were suspected intrauterine growth restriction, severe fetal malformations and intrauterine fetal demise. We used a composite outcome as an indicator of neonatal morbidity and mortality. RESULTS After the introduction of the breech clinic, we observed a significant increase in planned vaginal delivery from 7.4% (12/162) to 53.0% (61/115) (OR: 13.5; 95% CI: 6.7-27.0). The effective vaginal breech delivery rate (planned and unexpected) significantly increased from 4.3% (7/162) pre-implementation of breech clinic to 43.5% (50/115) post-implementation (OR: 17.0; 95% CI: 7.3-39.6). Neonatal outcomes were not statistically different between the before and after periods. CONCLUSION The introduction of a dedicated breech clinic has led to an increase in vaginal deliveries for breech babies without adversely affecting neonatal outcomes.

Abstract
BACKGROUND In allergic rhinitis, a relevant outcome providing information on the effectiveness of interventions is needed. In MASK-air (Mobile Airways Sentinel Network), a visual analogue scale (VAS) for work is used as a relevant outcome. This study aimed to assess the performance of the work VAS work by comparing VAS work with other VAS measurements and symptom-medication scores obtained concurrently. METHODS All consecutive MASK-air users in 23 countries from 1 June 2016 to 31 October 2018 were included (14 189 users; 205 904 days). Geolocalized users self-assessed daily symptom control using the touchscreen functionality on their smart phone to click on VAS scores (ranging from 0 to 100) for overall symptoms (global), nose, eyes, asthma and work. Two symptom-medication scores were used: the modified EAACI CSMS score and the MASK control score for rhinitis. To assess data quality, the intra-individual response variability (IRV) index was calculated. RESULTS A strong correlation was observed between VAS work and other VAS. The highest levels for correlation with VAS work and variance explained in VAS work were found with VAS global, followed by VAS nose, eye and asthma. In comparison with VAS global, the mCSMS and MASK control score showed a lower correlation with VAS work. Results are unlikely to be explained by a low quality of data arising from repeated VAS measures. CONCLUSIONS VAS work correlates with other outcomes (VAS global, nose, eye and asthma) but less well with a symptom-medication score. VAS work should be considered as a potentially useful AR outcome in intervention studies.

Abstract
Background:Osteoarthritis (OA) is frequently regarded by patients and health care providers as a normal consequence of ageing (1). On the other hand, it is well established that rheumatoid arthritis (RA) is a pathological condition requiring prompt and efficacious treatment and in which remarkable progresses have been achieved in the last decades. Pain and physical limitations are hallmarks of both conditions. Some previous studies suggest that OA and RA may have a similar burden (2,3).Objectives:To compare levels of pain, physical disability and health-related quality of life in patients with primary hand osteoarthritis (hOA) and with RA: active disease (aRA) or in remission (rRA).Methods:Observational cross-sectional study including patients of two clinical centres with hOA and RA, either in remission or with active disease (at least two swollen and/or tender hand joints). Matching for sex and age was performed. Patients were asked to complete a survey consisting of visual analogic scale (VAS) for pain, Health Assessment Questionnaire (HAQ) and Short Form 36 (SF36). Mean values for each domain were compared between the three groups using one-way ANOVA test with significance accepted for p<.05.Results:Thirty patients with hOA and 93 with RA (33 with aRA and 60 with rRA) were included. All patients were caucasian females with no significant differences in age between groups. Patients with hOA reported higher levels of pain in comparison with aRA patients (mean VAS 57.3vs49.3mm, respectively, p=.265) and with rRA patients (57.3vs28.6mm, respectively, p<.001) [F(2.120)=25.907, p<.001]. Regarding physical function, patients with hOA reported levels of disability similar to rRA patients, but significantly lower disability than patients with aRA [F(2.120)=6.962, p=.001]. Patients with hOA evaluated their quality of life significantly better than patients with aRA and in similar levels to patients with rRA, as measured by mental health and general health status domains of SF36.Conclusion:Our results show that hOA may have similar or even higher burden of pain than RA; this is in line with previous studies, although most of them did not consider the level of inflammatory activity of RA. On the other hand, patients with hOA seem to preserve function and have better health-related quality of life despite the higher levels of pain. These results highlight OA as a cause of severe pain, which should lead us to try an optimal symptom control for these patients. These findings should also encourage rheumatologists to endeavor efforts to perform more studies in the field of OA, to better understand its pathogenesis and to eventually find disease modifying drugs.References:[1]Gignac MAM, Davis AM, Hawker G, Wright JG, Mahomed N, Fortin PR, et al. “What do you expect?

Abstract
Background:Although spondyloarthritis (SpA) is primarily a musculoskeletal condition, ocular involvement is an important clinical feature and contributes to the burden of disease. Acute anterior uveitis (AAU) is classically described as the most frequent extra-articular manifestation of SpA and in some cases the first clinical presentation. The prevalence of AAU varies according to the subtype of SpA. In a systematic literature review, the mean prevalence of AAU was 32.7% and a positive association between HLA-B27 positivity, axial SpA, male sex and uveitis has been reported (1). More recently, some cross-sectional studies have described lower odds of spondyloarthritis-related uveitis (SpA-U) in smokers than in patients who are ex smokers or never smokers (2). Predictors of SpA-U are poorly defined in literature and the influence of smoking status remains controversial.Objectives:To analyse the factors associated with uveitis in SpA patients in a Tertiary Rheumatology Center.Methods:An observational cross-sectional study was performed including patients fulfilling the ASAS criteria for axial SpA with a follow-up visit between January and June 2019. Clinical patients’ charts were reviewed and the following variables were considered: age, gender, history of uveitis (confirmed by ophthalmologist observation), number of AAU episodes, smoking status (never smoker or ever smoker), HLA-B27, disease duration, disease involvement (exclusively axial or axial and peripheral), history of enthesitis and syndesmophytes. History of AAU and associated variables were determined in this subset of patients.Statistical analysis was performed with logistic regression model. P value <.05 was defined as statistically significant.Results:The study included 164 patients (62.3% men) with median age of 44.0 years (IQR 37 to 54) and a median disease duration of 14.6 years (IQR 9.28 to 20.32). SpA diagnosis was ankylosing spondylitis in 70.7% cases and the remaining were non-radiographic axial SpA. HLA-B27 was positive in 84.8%, 31.1% of patients were ever smokers and 21% had both axial and peripheral joint involvement. Twenty four percent of patients had at least one AAU episode. Recurrence of uveitis occurred in 70% of patients. Ever smoking (OR=2.256; 95%CI [1.077-4.276]; p<.05) and syndesmophytes (OR=2.125; 95%CI [1.009-4.475]; p<.05) showed a statistically significant association with uveitis in univariated logistic regression. Althougth not statistically significant, a trend to association was found between smoking and recurrence of AAU (OR=2.235; 95%ICI [.973-5.135], p=.058). In multivariated logistic regression only ever smoking was independently associated with uveitis (OR=2.542; 95%CI [1.007-6.420]; p<.05). We did not find association between presence of uveitis and gender, age, disease duration, disease involvement, HLA-B27 positivity and enthesitis.Conclusion:Contrary to few cross-sectional studies showing a possible protective effect of smoking in SpA-U, and in line with new data from Zhaoet al(3), we report a statistically significant independent association between history of smoking and uveitis. Nevertheless, we emphasize the need of more studies to confirm these findings.References:[1] Zeboulon N, et al.

Abstract
Summary Objective. Describing routine procedures, clinical profile and evolution of patients treated in a chronic urticaria CU reference center of a university hospital. Methods. Retrospective analysis of clinical records and database of CU patients registered between March 2011 and February 2016 in a reference center. Besides demographic characteristics, disease duration, comorbidities, angioedema, thyroid lab tests, urticaria subtypes, provocation tests, UAS and CUQ2oL scores were recorded. Patients with 3 or more visits were included in analysis regarding the first and last visits, to evaluate pharmacological treatment and differences of UAS/CUQ2oL scores, antihistamines anti H1 dosages and need of other medications, according urticaria subtypes. Results.During the study, 252 patients were attended, 200 with CU, including 162 women, median age 45 years, perc 25 - 75 = 27 - 58, and median duration of symptoms before diagnosis 24 months, perc 25 - 75 = 9 - 60. Regarding the etiology, 166 (83%) patients had chronic spontaneous urticaria (CSU), 34 (17%) had isolated chronic inducible urticaria (CIndU) and 66 (33%), CSU with CIndU. Among the 123 patients followed up for 3 or more visits, first prescription to 106 (86.2%) patients was monotherapy with anti-H1, and associations with other medications were prescribed to 17 (13.8%). At the last visit, 94 (76.5%) received antihistamines, and 29 (23.5%) used associations. Patients with CSU + CIndU + ASST positive need more association of anti-H1 with other medications than patients with CSU + CIndU and only CIndU (÷2 = 7.998; p 0.01). Between first and last visits, CUQ2oL mean scores changed from 35.7 (± 21.9) to 22.6 (± 21.0) (Z = -4.833 p less than 0.000). Conclusions.Most of the patients presented CSU, frequently associated with CIndU. There was an improvement in the patients' quality of life during the follow-up period. All patients were treated with antihistamines and there was a great need for doses above the standardized and also for combination with other medications, especially in patients with concomitance of urticaria subtypes.

Abstract
Hepatitis C virus (HCV) infection is a worldwide health problem. Nowadays,
direct-acting antiviral agents (DAAs) are the main treatment for HCV; however,
the high level of virus variability leads to the development of
resistance-associated variants (RAVs). Thus, assessing RAVs in infected patients
is important for monitoring treatment efficacy. The aim of our study was to
investigate the presence of naturally occurring resistance mutations in HCV NS3
and NS5 regions in treatment-naïve patients. Ninety-six anti-HCV positive serum
samples from blood donors at the Center of Hematology and Hemotherapy of Santa
Catarina State (HEMOSC) were collected retrospectively in 2013 and evaluated in
this study. HCV 1a (37.9%), 1b (25.3%), and 3a (36.8%) subtypes were found. The
frequency of patients with RAVs in our study was 6.9%. The HCV NS5b sequencing
reveled 1 sample with L320F mutation and 4 samples with the C316N/R
polymorphism. The analysis of the NS3 region revealed the D168A/G/T (3.45%),
S122G (1.15%), and V55A (2.3%) mutations. All samples from genotype 3a (36.8%)
presented the V170 I/V non-synonymous mutation. In conclusion, we have shown
that mutations in NS3 and NS5b genes are present in Brazilian isolates from
therapy-naïve HCV patients.
