Abstract
The inherent scalability, low production cost and mechanical flexibility of laser-induced graphene (LIG) combined with its high electrical conductivity, hierarchical porosity and large surface area are appealing characteristics for many applications. Still, other materials can be combined with LIG to provide added functionalities and enhanced performance. This work exploits the most adequate electrodeposition parameters to produce LIG/ZnO nanocomposites. Low-temperature pulsed electrodeposition allowed the conformal and controlled deposition of ZnO rods deep inside the LIG pores whilst maintaining its inherent porosity, which constitute fundamental advances regarding other methods for LIG/ZnO composite production. Compared to bare LIG, the composites more than doubled electrode capacitance up to 1.41 mF cm-2 in 1 M KCl, while maintaining long-term cycle stability, low ohmic losses and swift electron transfer. The composites also display a luminescence band peaked at the orange/red spectral region, with the main excitation maxima at ~ 3.33 eV matching the expected for the ZnO bandgap at room temperature. A pronounced sub-bandgap tail of states with an onset absorption near 3.07 eV indicates a high amount of defect states, namely surface-related defects. This work shows that these environmentally sustainable multifunctional nanocomposites are valid alternatives for supercapacitors, electrochemical/optical biosensors and photocatalytic/photoelectrochemical devices.

Abstract
In children, spontaneous mediastinitis is a rare, severe and commonly misdiagnosed disease. Although standard of care treatment frequently involves surgery, we report a case of mediastinitis in a five-year-old child, successfully treated with 4 weeks of intravenous antibiotics. Ultrasound imaging was used to monitor patient response to conservative treatment while reducing radiation exposure.

Abstract
BACKGROUND Allergic diseases appear to be associated with mood disorders. However, particularly regarding allergic rhinitis (AR), such association has not been adequately systematically reviewed. Therefore, we conducted a systematic review and meta-analysis to quantify the association between AR and depression and anxiety. METHODOLOGY We performed an electronic search of PubMed, Web of Science and Scopus for observational studies assessing the association between AR and depression and anxiety. Such association was quantified by means of random-effects meta-analysis, with estimation of pooled odds ratio (OR). Sources of heterogeneity were explored by subgroup analysis. RESULTS We included a total of 24 primary studies, of which 23 assessed depression and 11 assessed anxiety. Of these, 12 studies presented OR from multivariable regression models and were included in our meta-analysis. AR was associated with higher odds of depression and anxiety. CONCLUSIONS AR appears to be associated with high risk of depression and anxiety. While our results point to the importance of mental comorbidities among patients with AR, longitudinal studies are needed adopting uniform definitions and presenting results stratified by AR severity.

Abstract
PURPOSE Most studies regarding the value of post lumpectomy imaging (PLI) studies rely on mammography alone and are often focused on patients that present with suspicious microcalcifications or in situ disease. This way, its true benefit remains controversial, which explained the heterogeneity between centers. This is the first study to evaluate the role of mammography with breast and axillary ultrasound undertaken before radiotherapy in patients with conservatively managed invasive and/or in situ carcinoma with negative margins. MATERIALS AND METHODS In this retrospective study, medical records for patients referred to our External Radiotherapy Unit between January 2018 and December 2019 were reviewed. RESULTS A total of 1251 patients (1262 breasts) were analyzed. A total of 3.4% had suspicious findings for local residual breast disease, with 1.0% having a re-excision positive for residual malignancy. Presentation with microcalcifications alone (OR=4.854), extension of microcalcifications>3cm (OR=13.500), histologic subtype pure ductal carcinoma in situ (OR=12.348), presence of invasive carcinoma≤1mm of the pathological margins (OR=4.630), stage pTis (5.630), and absence of invasive component (OR=4.629), were associated with an increased risk for residual malignancy. Only one patient (0.1%) had nodal residual involvement. CONCLUSION PLI detected residual local cancer in 1.0% of the patients. PLI plays an important role in the evaluation of patients undergoing breast-conserving therapy with negative margins. The major question that remains is whether it changes survival outcomes.

Abstract
Foliar vegetables contaminated with fecal residues are an important route of transmission of intestinal parasites to humans. The aim of this study was to evaluate the presence of parasitic forms of protozoa and helminths on lettuces (Lactuca sativa) and collard greens (Brassica oleracea) sold in street- and supermarkets in the city of Aparecida de Goiânia, Goiás, Brazil. A total of 30 samples of each vegetable (15 samples from each supermarkets and street markets) was analyzed. All samples were processed by spontaneous sedimentation method and centrifugal flotation. In 45% of the samples, immature forms of intestinal parasites were identified with 66.7% helminths eggs and 33.3% protozoan cysts or oocysts. Significantly more lettuce samples were contaminated with eggs, cysts or oocyst of at least one parasite than collard green samples (U=216; Z=-3.45; P <0.001). The parasitic forms were identified morphologically up to the family level with eggs of Ancylostomatidae, Strongyloididae, Ascarididae and Taeniidae, or oocysts of Eimeriidae, to the genus with Cystoisospora sp. and Toxocara sp., and to the species level with Cystoisospora canis, Dipylidium caninum and Hymenolepis nana. The presence of these infective agents in lettuce and collard green from both street- and supermarkets highlights the high risk of spreading parasites by eating raw vegetables sold in Aparecida de Goiânia.

Abstract
Background:Fragility fractures (FF) are fractures that result from mechanical forces that would not ordinarily result in fracture, known as low-level (or ‘low energy’) trauma.1 Studies have shown that history of wrist fracture increases the risk for subsequent FF.2Objectives:To assess predictive factors of FF occurring after a wrist fracture.Methods:Retrospective monocentric study that included patients with a wrist FF observed at the emergency department (ED) in a tertiary center, between 1st January 2017 and 31st December 2018. Wrist fractures were identified through the 10th International Classification of Diseases and FF were identified after revision of the clinical record. Patients with relevant missing data were excluded. Seven hundred thirty-three wrist FF were identified. After calculating a representative sample (90% confidence interval), 188 patients were included. Their clinical records until 31th December 2020 (2 to 3 years after FF) were reviewed. SPSS was used for statistical analysis and significance level was defined as 2-sided p<0.05. In multivariate analysis we included variables with a significant association in univariate analysis and those with clinical relevance (reported in others studies).Results:Wrist fractures represented 44.3% of the FF observed at the ED.Most patients were woman (83.5%) with a mean age of 70.7 (SD=11.2) years-old at the time of their wrist fracture. A previous FF was seen in 22.9% of patients and 13.3% had a new FF during the follow-up period.We found an association between the occurrence of a new FF and the number of comorbidities (p=0.012), number of visits to the ED due to falls (p<0.001), previous diagnosis of chronic pulmonary disease (p=0.029) and hematologic pathologies (p=0.047), and the need for hospitalization at time of the wrist FF (p=0.018).No associations were found between the age at the wrist fracture time, number of drugs taken daily nor its type (anxiolytics, antiepileptics, corticoids), previous fractures (and localization), overweight/obesity and other cardiovascular risk factors, endocrinopathies, psychiatric or neurologic disease or other comorbidities.After adjustment for age, gender, anti-osteoporotic treatment and comorbidities, the main predictors of a new FF were visits to the ED for falls (p=0.005), chronic pulmonary disease (p=0.040), hematologic pathologies (p=0.004) and need for hospitalization (p=0.040) (table 1).Table 1.Multivariate analyses: linear multiple regression for predictive factors of new fragility fracture.DeterminantsUnstandardized CoefficientsBStandardized Coefficients Beta95.0% CIp-valueAge-0.0250.9750.924 – 1.030NSGender2.0657.8890.757 – 82.165NSNumber of comorbidities0.1861.2040.846 – 1.713NSVisits to the emergency service for falls-2.1360.1180.026 – 0.5290.005Chronic pulmonary disease-1.3260.2660.075 – 0.9400.040Hematologic pathologies-4.2960.0140.001 – 0.2550.004Need for hospitalization-2.7640.0630.004 – 0.8870.040Anti-osteoporotic treatment0.1571.1700.227 – 6.017NSCI: Confidence Interval; NS: non-significant;Conclusion:Certain comorbidities seem to be associated with new FF.

Abstract
Background:Several data indicate that seronegative rheumatoid arthritis (RA-) and seropositive RA (RA+) may have different mechanisms and prognosis, being well established that rheumatoid factor (RF) and anti-citrullinated peptide antibodies (ACPA) have diagnostic and prognostic value. Several conditions, like peripheral spondyloarthritis (SpA), psoriatic arthritis or crystal-related arthropathies may mimic the presentation of RA. Mechanisms and treatment of each of these conditions differ significantly. The authors speculate that RA- may be overdiagnosed in the setting of seronegative chronic inflammatory arthritis and that musculoskeletal ultrasound (US) may help us to better classify these patients through the identification of characteristic lesions of the mentioned diseases.Objectives:To compare the frequency of US lesions found in joints and entheses between RA- and RA+ patients.Methods:Cross-sectional study: systematic US evaluation of ten joints, twelve entheses and both flexor and extensor tendons of four fingers (Table 1) in consecutive RA- patients. RA+ patients matched for sex and age were recruited. RA- patients included met every of the following criteria: history of chronic polyarthritis, RF and ACPA negativity, no extra-articular features of SpA or RA nor family history of SpA, no suspected crystal-related arthritis.Results:Twenty-one RA- patients were included and twenty RA+ patients were recruited as controls. No differences between groups were found in sex, age, body mass index, time of disease evolution or use of biological therapy.RA- patients had a significantly higher number of entheseal structural and/or inflammatory lesions than RA+ patients (median 2.0 vs. 0.5, U 111.5, p=.008**), with triceps enthesitis being significantly more frequent in RA- patients (p=.036*). In total, 18.7% of RA- entheses had enthesitis lesions vs. only 8.3% of RA+ entheses. One RA- patient had ultrasonographic features of dactylitis which was not clinically evident.As expected, considering the role of RF and ACPA in erosive RA, RA- patients had a significantly lower number of joints with erosions compared to RA+ patients (median 0.0 vs. 3.0, U 64.5, p<.001***), with significant differences in every considered joint. Erosions were found in 6.7% of RA- joints vs. 32.0% RA+ joints.Additionally, two RA- patients had hyperechogenic foci in knee cartilage or carpal fibrocartilage suggestive of calcium pyrophosphate deposition.Table 1.Comparative frequency of ultrasound lesions found in joints and entheses of RA- and RA+ patients.RA-(n=21)RA+(n=20)p-valueMdn number of ENTHESES with any lesion per patient ± IQR2.0 ± 3.00.5 ± 2.0.008**Triceps – n (%)8 (38.1%)2 (10.0%).036*Quadriceps – n (%)9 (42.9%)6 (30.0%).393Superior patellar – n (%)4 (19.0%)1 (5.0%).169Inferior patellar – n (%)---Achilles – n (%)9 (42.8%)4 (20.0%).116Plantar fascia – n (%)5 (23.8%)1 (5.0%).089DACTYLITIS – 2nd + 5th finger – n (%)1 (4.8%)--Mdn number of joints with EROSIONS per patient ± IQR0.0 ± 1.03.0 ± 3.0<.001***Ulnar styloid process – n (%)5 (23.8%)11 (55.0%).041*Metacarpophalangeal 2 – n (%)3 (14.3%)11 (55.0%).006**Metacarpophalangeal 5 – n (%)1 (4.8%)10 (50.0%).001**Metatarsophalangeal 1 – n (%)-3 (15.0%)-Metatarsophalangeal 5 – n (%)3 (14.3%)11 (55.0%).006**CHONDROCALCINOSIS – triangular fibrocartilage + knee – n (%)2 (9.5%)--DOUBLE CONTOUR – any joint – n (%)---RA- – seronegative rheumatoid arthritis; RA+ – seropositive rheumatoid arthritis Mdn – median; IQR – interquartile range; n (%) – absolute number (percentage) of patients with the indicated lesion.Conclusion:We found that some patients diagnosed with RA- had, in fact, ultrasonographic features of different diseases, namely enthesitis/dactylitis and crystal deposition. These data suggest that RA- may be overdiagnosed in clinical practice. Systematic US evaluation of joints and entheses may provide valuable diagnostic information in patients with chronic inflammatory seronegative arthritis and improve patient care.Disclosure of Interests:None declared

Abstract
Abstract
Funding Acknowledgements
Type of funding sources: None.
Background
Syncope is a common reason for emergency department attendance. This entity may be associated with significant morbidity and mortality and its differential diagnosis is not straightforward. Arrhythmic causes include tachycardia and bradycardia; the later may require pacemaker implantation. Many hospitals lack a dedicated syncope unit to approach these patients. So, patients’ triage may fall into medical or surgical (trauma) areas.
Purpose
To describe the population of patients that required permanent pacemaker implantation in the year of 2019, particularly those who had a previous visit to the emergency department with syncope or presyncope.
Methods
Single-center descriptive analysis of patients that implanted a permanent pacemaker in 2019 (inclusion criteria). Additional information was collected in patients with emergency department visits in the 365 days that preceded the device implantation.
Results
In 2019, a total of 398 patients were admitted for pacemaker implantation in 2019, 55% male (n = 218), 45% female (n = 180), with mean age of 79 years. Regarding indications for pacing, 41% (n= 156) had complete atrioventricular (AV) block, 26% (n = 105) had a second degree AV block, 16% (n = 64) had sinus node dysfunction, 13.5% (n = 53) had atrial fibrillation with slow ventricular conduction, and 3.5% (n = 14) had other indications.
Twenty-two percent (n = 88) of patients had a previous visit to the emergency department (other than the ones that triggered the pacemaker implantation) with complaints of syncope (60%) or presyncope (40%). Of these, 73% (n = 64) were referred to a medical area and 27% (n = 24) were referred to a surgical area; 40 patients presented with traumatic lesions (68% cranioencephalic trauma and 32% other traumas). Of the 88 patients, only 67% (n = 59) performed an ECG and only 23% (n = 20) were referred for observation by a cardiologist in the emergency department.
Comparing medical and surgical triage, we observe that patients referred to the surgical area were less likely to perform an ECG and to be observed by a cardiologist (with statistical significance).
Conclusions
Our work describes a common problem in hospitals without dedicated syncope evaluation units. As all the patients ended up implanting a pacemaker, it is interesting to observe that 22%of these had a "warning" visit to the emergency and 33% of the last did not get and ECG. Also, trauma-oriented approaches result in a lower likelihood of performing a complete evaluation of the cause of the syncopal event. This analysis highlights the need for a comprehensive and multidisciplinary approach of patients presenting with syncope and presyncope to promote early identification and treatment of arrhythmic causes, reducing patient morbidity and healthcare costs.

Abstract
Breast cancer is the most common cancer affecting women worldwide. Adherence to breast cancer screening guidelines is frequently lower in racial, ethnic and cultural minority populations and is affected by potential inequities or barriers to screening that these minorities face. Therefore, the aim of the present study was to collect information from different minority groups worldwide, assess adherence to breast cancer screening and evaluate barriers or limitations causing non-adherence, which should facilitate the development of effective interventions. A search was conducted through PubMed and Web of Science. Studies were considered as eligible if they met the following criteria: i) Female patients; ii) breast cancer screening program implemented in the country; iii) minority groups; iv) asymptomatic; v) report written in Portuguese or English; vi) study published from 2015 onwards. The Critical Appraisal Skills Programme checklist was used for qualitative studies and the Strengthening The Reporting of Observational Studies in Epidemiology checklist for cross-sectional studies. From the 348 initial articles, 86 were removed due to duplication and 19 were selected, analyzed and summarized, accordingly. Of the 19 studies included, 5.3% were classified as high quality, 52.6% as moderate to high and 42.1% as moderate. A total of 15 studies were cross-sectional and 4 were qualitative, collectively including 250,733 women. The rate of adherence to mammogram in different minorities was evaluated, obtaining a mean value of 49.7% in the last 2 years, and statistically significant barriers were selected and divided into sociodemographic; personal; ethnic, cultural and religious; and external factors. The characteristics of each population play a major role in the population's breast health practices. If the population, adherence rates, barriers and inequities are carefully studied, screening models may be customized and participation to breast cancer screening can be optimized, thereby reducing the high breast cancer-associated mortality.

Abstract
We aimed to determine how Portuguese physicians handle major bleeding. We also aim to establish global diagnostic and therapeutic recommendations to be followed in clinical practice by using a step-wise approach of evidence generation. This study followed a three-step process: a steering committee desk review, a Delphi technique, an expert panel meeting. A modified 3-round Delphi including 31 statements was performed. Questions were answered in a five-point Likert-type scale. Consensus threshold was established as a percentage of agreement among participants ≥90% in the first round, and ≥85% in the second and third rounds. The level of consensus achieved by panelists was discussed with the scientific committee (January-2020). Fifty-one physicians participated in the study (compliance rate >90%). Analyzing the three rounds, consensus was reached on 20 items (64.5%) in the first, 4/11 items (36.4%) in the second and 6/7 items (85.7%) in the third. One statement about administration of clotting factor concentrates for bleeding control did not reach consensus. A high level of consensus was reached toward the need for implementing Patient Blood Management strategies in Portuguese hospitals, reduce exposure to allogeneic blood components, to use goal directed therapies for acquired bleeding management, and the need for evaluating blood transfusion indirect costs. A final version with 12 recommendations was built, according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Our results provide critically appraised and updated evidence on bleeding coagulopathies management in Portugal. Additional studies, mainly about indirect costs of blood transfusion, are needed.

Abstract
Acrylic acid is a value-added chemical used in industry to produce diapers, coatings, paints, and adhesives, among many others. Due to its economic importance, there is currently a need for new and sustainable ways to synthesise it. Recently, the focus has been laid in the use of Escherichia coli to express the full bio-based pathway using 3-hydroxypropionate as an intermediary through three distinct pathways (glycerol, malonyl-CoA, and β-alanine). Hence, the goals of this work were to use COPASI software to assess which of the three pathways has a higher potential for industrial-scale production, from either glucose or glycerol, and identify potential targets to improve the biosynthetic pathways yields. When compared to the available literature, the models developed during this work successfully predict the production of 3-hydroxypropionate, using glycerol as carbon source in the glycerol pathway, and using glucose as a carbon source in the malonyl-CoA and β-alanine pathways. Finally, this work allowed to identify four potential over-expression targets (glycerol-3-phosphate dehydrogenase (G3pD), acetyl-CoA carboxylase (AccC), aspartate aminotransferase (AspAT), and aspartate carboxylase (AspC)) that should, theoretically, result in higher AA yields.

Abstract
Tetragonal Er0.5Nb0.5O2 and monoclinic ErNbO4 micro- and nanoparticles were prepared by the citrate sol–gel method and heat-treated at temperatures between 700 and 1600 °C. ErNbO4 revealed a spherical-shaped crystallite, whose size increased with heat treatment temperatures. To assess their optical properties at room temperature (RT), a thorough spectroscopic study was conducted. RT photoluminescence (PL) spectroscopy revealed that Er3+ optical activation was achieved in all samples. The photoluminescence spectra show the green/yellow 2H11/2, 4S3/2→4I15/2 and red 4F9/2→4I15/2 intraionic transitions as the main visible recombination, with the number of the crystal field splitting Er3+ multiplets reflecting the ion site symmetry in the crystalline phases. PL excitation allows the identification of Er3+ high-energy excited multiplets as the preferential population paths of the emitting levels. Independently of the crystalline structure, the intensity ratio between the green/yellow and red intraionic transitions was found to be strongly sensitive to the excitation energy. After pumping the samples with a resonant excitation into the 4G11/2 excited multiplet, a green/yellow transition stronger than the red one was observed, whereas the reverse occurred for higher excitation photon energies. Thus, a controllable selective excited tunable green to red color was achieved, which endows new opportunities for photonic and optoelectronic applications.

Abstract
BACKGROUND Student life during the university period is characterized by many changes in eating behaviors and dietary patterns due to adaptation to a new environment, study stress, lack of proper time management, and busy class schedules. These unhealthy actions may be detrimental to cognitive processing and influence academic performance, which is related to professional success. AIM To assess different eating patterns in Portuguese university students and relate them to several sociodemographic variables. METHODS Cross-sectional information about eating behavior was assessed using the Dutch Eating Behavior Questionnaire in 169 students between 18 and 50 years of age, from the Universidade Lusófona de Humanidades e Tecnologias and from different academic courses, some related to health sciences. Mediterranean diet adherence was also assessed using a validated 14-item questionnaire. RESULTS According to the analyses of the 169 participants included in the sample, 33 presented restrained eating behavior, with 73 presenting external and 63 emotional. In the same line of thought, 62.10% of nutrition sciences students presented emotional eating behavior and overall it was observed that these students were more likely to have emotional eating behavior. Otherwise, presenting restrained eating behavior was statistically associated with being older and having higher Mediterranean diet adherence. CONCLUSIONS Studying nutrition sciences was associated with having emotional eating behavior. Older students and those who adhere more closely to the Mediterranean diet were associated with having restrained eating behavior.

Abstract
BACKGROUND Remission/ low disease activity (LDA) are the main treatment goals in rheumatoid arthritis (RA) patients. Two tools showing the ability to predict golimumab treatment outcomes in patients with RA were published. OBJECTIVES To estimate the real-world accuracy of two quantitative tools created to predict RA remission and low disease activity. METHODS Multicenter, observational study, using data from the Rheumatic Diseases Portuguese Register (Reuma.pt), including biologic naïve RA patients who started an anti-TNF as first-line biologic and with at least 6 months of follow-up. The accuracy of two matrices tools was assessed by likelihood-ratios (LR), sensitivity (SN), specificity (SP), positive predictive value (PPV), negative predictive value (NPV) and area under the ROC curve (AUC). RESULTS 674 RA patients under first-line anti-TNF (266 etanercept, 186 infliximab, 131 adalimumab, 85 golimumab, 6 certolizumab pegol) were included. The median (IQR) age was 53.4 (44.7-61.1) years and the median disease duration was 7.7 (3.7-14.6) years. The majority were female (72%). Most patients were RF and/or ACPA positive (75.5%) and had erosive disease (54.9%); 58.6% had comorbidities. At 6-months, 157 (23.3%) patients achieved remission (DAS28 ESR < 2.6) and 269 (39.9%) LDA (DAS28 ESR ≤ 3.2). Area under the curve for remission in this real-world sample was 0.756 [IC 95% (0.713-0.799)] and for LDA was 0.724 [IC 95% (0.686 -0.763)]. The highest LR (8.23) for remission state was obtained at a cut-off ≥ 67%, with high specificity (SP) (99.6%) but low sensitivity (SN) (3.2%). A better balance of SN and SP (65.6% and 73.9%, respectively) was observed for a cut-off >30%, with a LR of 2.51, PPV of 43.3% and NPV of 87.6%. CONCLUSION In this population, the accuracy of the prediction tool was good for remission and LDA. Our results corroborate the idea that these matrix tools could be helpful to select patients for anti-TNF therapy.

Abstract
Abstract
Introduction
Public health care acknowledges socioeconomic factors as one of the multiple facets to promote or protect individual or collective health. Understanding and being more acquainted with the dynamics carried out in riverside communities is fundamental to investing in policies aimed at fighting diseases and illnesses that are particular to those communities.
Objective
Describing socioeconomic characteristics, healthcare infrastructure, and occupational activities of population from riverside communities along Tapajós river, Brazil.
Methodology
A descriptive study with 96 residents of communities of Tapajós river, Brazil. Participants have answered a semi-structure questionnaire and the analyses were descriptive and the variable categories were expressed as frequencies.
Results
There was a predominance of male participants (77.09%), incomplete elementary school (58.51%), involved in agricultural sector (85.10%), with a family income up to 1 minimum wage (68.81%). However, only 21.50% have declared making their living exclusively out of agriculture. Seedlings and seeds are mainly obtained through an exchange system running inside the community. In relation to infrastructure, the water comes from artesian wells (68.88%) and 51.63% claim not treating water whatsoever. All interviewees mentioned the lack of a sewage system and residues are taken to a rudimentary cesspool (76.59%). Waste produced by the community is burned out (93.61%). The main difficulties pointed out by the interviewees were: transportation (44.94%), health (32.14%), communication (21.42%) and government cooperation (15.47%).
Conclusions
The communities in this project show similar structural dynamic based on subsistence family agriculture and poor infrastructure of basic services. The data collected can be the basis for future public policies aiming at the promotion of food production autonomy, economic autonomy, and improvement of health indicators of these communities.
Key messages
Contextualizing the structural dynamic of vulnerable populations is key to plan actions aimed at tackling and dealing with social determinants involved in the health-illness process. Contextualizing the structural dynamic of vulnerable populations is fundamental to guide strategies aimed at intervening in the social and health determinants.

Abstract
Abstract
Introduction
Riverside population lack basic sanitation infrastructure and access to healthcare. In addition, locals encounter difficulties in accessing basic health care due to climate variability and fluvial activity which results in tidal distortion and attenuation. Quality of life is a broad concept and its measurement should be useful to identify determining and conditioning factors in health-illness process which would be key to the guidance of health public policy measures in a specific community. This study aims at assessing the quality of life of Tapajós and Cupari riverside communities in Pará, Brazil.
Methods
A cross-sectional and descriptive study composed of a group of patients aged 18 and over who have sought care during the volunteer health expedition in the Tapajós and Cupari rivers between mid-July and August 2019. The team of students and professors conducting the survey adopted the WHOQOL-bref questionnaire as a measure of quality of life. The questionnaire consists of 25 questions and 5 domains: physical health, psychological, social relationships, environment, and self-assessment of quality of life. Individual scores vary between 4 and 20. Scores ≤ 10 suggest low quality of life whereas >10 suggest higher quality of life. This statistical analysis was carried out in the SPSS program and was described by means of summary measures: minimum, maximum, median, and standard deviation. Outcomes:The five domains scored >10, with the highest being the psychological domain (16,48, dp = 1,71) and the lowest the environment (14,12 dp = 1,99).
Conclusions
In spite of inherent difficulties generally found in riverside communities, participants reported high perception of quality of life in all domains. The lowest overall perception was the environment domain. This result confirms not only the barriers of physical infrastructure but also access to quality services as a negative health and life determinant.
Key messages
Assessing the quality of life is key to determine which factors influence the health-illness process within a community. Assessing the quality of life is fundamental to guide strategies aimed at intervening in social determinants.

Abstract
OBJECTIVES To evaluate belimumab effectiveness and safety in real-life Portuguese patients with Systemic Lupus Erythematosus (SLE). MATERIALS AND METHODS Multicenter cohort study including all SLE patients treated with belimumab in seven Portuguese rheumatology centers. Demographic, clinical and serological data were collected at baseline, 6, 12 and 24 months of treatment with belimumab. To evaluate effectiveness we used SLE Responder Index (SRI) rates and changes in SELENA-SLEDAI. Safety was evaluated by the number of adverse events. RESULTS Thirty-eight patients were included: 37 (97.4%) female, with a mean age of 46.2±13.9 years. Mean SELENA-SLEDAI was 8.2±3.9, 78.8% had elevated anti-double-stranded DNA (anti-dsDNA) antibodies and 72.7% had complement consumption at baseline. Multiorgan involvement was the leading cause for the use of belimumab. SRI response was achieved in 51.9%, 60% and 91.7% at 6, 12 and 24 months of belimumab treatment, respectively. LUNDEX adjusted SRI response rates were 45.4%, 45.0% and 45.8% at 6, 12 and 24 months of belimumab, respectively. Mean SELENA-SLEDAI, anti-dsDNA antibodies and daily prednisolone dosage decreased significantly from baseline to 6, 12 and 24 months and C3 levels increased significantly at 12 months of belimumab treatment. Five patients presented adverse events (infections in three cases) and eleven patients discontinued belimumab (four due to inefficacy, three due to adverse events and four were lost to follow-up). CONCLUSIONS Our study confirmed, in real-life Portuguese patients with active SLE, the effectiveness of belimumab in reduction of disease activity, immunological response and steroid-sparing, with a good safety profile.
