Abstract
UNLABELLED We aimed to evaluate the associations between information searching about public health and social measures (PHSM) and university students' digital health literacy (DHL) related to the new coronavirus (SARS-CoV-2) and COVID-19. METHODS This cross-sectional study included 3,084 Portuguese university students (75.7% females), with an average age of 24.2 (SD = 7.5). Sociodemographic data, DHL questionnaire and online information concerning PHSM were gathered. Cox proportional hazards models were performed. RESULTS Students who searched for personal protective measures achieved in shorter time sufficient "evaluating reliability" (HR = 1.4; 95% CI = 1.1; 1.7) and "determining relevance" (HR = 1.5; 95% CI = 1.2; 1.8). Searching for surveillance and response measures was associated with sufficient "determining relevance" (HR = 1.4; 95% CI = 1.1; 1.9). Finally, those students who searched for environmental, economic and psychosocial measures achieved in shorter time "determining relevance" (HR = 1.2; 95% CI = 1.0; 1.4). CONCLUSIONS Searching for PHSM was significantly associated with an increased likelihood of achieving sufficient DHL subscales in a shorter time. Further studies are needed, including developing strategies to increase the availability of high-quality information concerning public health and social measures and to improve (digital) health literacy.

Abstract
Objetivo: Describir las características clínicas, microbiológicas y los desenlaces de las bacteriemias primarias por S. pneumoniae ocurridas en población pediátrica hospitalizada en instituciones de alta complejidad, pertenecientes a la Red Neumocolombia (2017-2019). Metodología: Estudio observacional, descriptivo, longitudinal, exploratorio con alcance analítico, en donde se tomó información de las historias clínicas con hemocultivos positivos para S. pneumoniae sin otro foco infeccioso, realizados en los hospitales pediátricos, reportados a la Red Neumocolombia (2017-2019). Resultados: Durante el periodo de estudio se analizó información de 51 registros, 62,7% fueron hombres, la mediana de edad fue 25 meses (RIC 9-49). El síntoma predominante fue fiebre (78,4%), se reportó vacunación con Vacuna Neumocócica Conjugada decavalente (PCV-10) en 47%. El serotipo más frecuente fue 19A (39,4%). El porcentaje de resistencia antibiótica fue: eritromicina 43%, penicilina 25.4%, cefotaxima 11,7%. Los factores relacionados al ingreso a Unidades de Cuidado Intensivo Pediátrico (UCIP) fueron: dolor pleurítico (OR27,9; IC95%3,13 – 248,16 p=0,03), tos (OR6,04; IC95%1,46 – 24,88; p=0,013), dolor abdominal (OR 6,5; IC95%1,85 – 22,80; p=0,003), dificultad respiratoria (OR12; IC95%2,95 – 48,77 p=0,001), tirajes (OR22,71; IC95%4,65 – 141,90 p=0,001), cianosis (OR8,69; IC95%1,95 – 38,65 p=0,004), hipotermia (OR42,62; IC95%4,77 – 380,74 p=0,001), serotipo 19A (OR3,9;IC95%1,10 – 13,81 p=0,035). La letalidad fue del 11,7%. Conclusión: Después de la introducción de la vacuna PCV10 en Colombia en el año 2012 se reportaron cambios en la epidemiologia, con disminución de los serotipos vacunales, y aumento en el serotipo 19A, siendo uno de los factores que intervienen en el ingreso a UCIP por bacteriemia primaria. Se reporta aumento en la resistencia por eritromicina, penicilina y cefotaxima.

Abstract
INTRODUCTION Successful emotion regulation (ER) is critical for psychological health. Disturbances in this ability are associated with several psychiatric disorders. There are several self-report questionnaires to assess ER. However, there are no studies synthesising the evidence on their psychometric properties. We aim to identify all available instruments addressing ER in adolescents or adults and to critically appraise, compare and summarise the quality of their psychometric properties. For this, we will use COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) criteria. METHOD AND ANALYSIS The search process to identify eligible studies will be conducted in April 2021 including the ProQuest, PubMed, Scopus and Web of Science databases with no restriction in terms of publication date. Eligibility criteria include peer-reviewed research articles written in English or Spanish by means of patient-reported outcome measures focused on ER among participants of 13 years or older. We will assess the quality of measures according to the COSMIN Risk of Bias Checklist. The psychometric properties will be assessed by the COSMIN updated criteria for good measurement. The available evidence will be addressed by the Grading of Recommendations, Assessment, Development and Evaluations approach. Our findings will be synthesised independently for each measure, including information on their sample, theoretical model and psychometric properties when possible. ETHICS AND DISSEMINATION Ethical approval is not required, as this study does not involve any participants or collection of primary data. Results are expected to be published in a peer-reviewed journal in the field of youth mental health and presented at relevant meetings and conferences. PROSPERO REGISTRATION NUMBER CRD42021249498.

Abstract
Background Worldwide there is an overwhelming amount of information about COVID-19 circulating online, also named infodemic. Misinformation (the unintentional) and disinformation (the intentional) spreading of false information have proven to be very dangerous to public health. Hence, more than ever, people need skills for searching, evaluating and integrating information related to health in daily life, i.e., health literacy. Until now, little is known about the digital health literacy of university students and their information-seeking behaviour. Hence, this study aimed to analyse the associations between university students' digital health literacy and online information queries during the beginning of the COVID-19 pandemic (and infodemic) in Portugal. Methods A cross-sectional study of 3.084 Portuguese university students (75.7% females), with an average age of 24.2 (SD = 7.5), was conducted using an online survey. We used sociodemographic data (sex, age, subjective social status) and the digital health literacy questionnaire adapted to the specific COVID-19 context. Online information queries included the topics related to SARS-CoV-2 and COVID-19 searched by students. Logistic regression models were performed. Results Online information queries (e.g., individual measures to protect against infection, current spread of the virus, current situation assessments and recommendations) were associated with an increased odds of achieving sufficient digital health literacy. Conclusions Online information queries related to epidemiological and public health topics are significantly associated with digital health literacy in times of COVID-19. Further studies are needed, including programs that improve digital health literacy among university students and increase the availability of high-quality content information.

Abstract
We aim to evaluate the associations between digital health literacy (DHL) related to COVID-19 and online information-seeking behavior among university students. METHODS A total of 3.084 students (75.7% women), with an average age of 24.2 (SD = 7.5) participated in this cross-sectional study, most of whom (36.5%) were from social sciences and pursued a bachelor's degree (50.7%). Data on COVID-19-related DHL and online information-seeking behavior were collected using an online questionnaire. Logistic regression models were performed. RESULTS As the pandemic progressed, participants showed a lower chance of achieving a sufficient DHL (OR = 0.7; 95% CI = 0.6; 0.9). Using search engines more often (e.g., Google) (OR = 0.7; 95% CI = 0.5; 0.9), Wikipedia (OR = 0.7; 95% CI = 0.6; 0.9) and social media (e.g., Facebook) (OR = 0.7; 95% CI = 0.6; 0.9) decreased the likelihood of achieving sufficient DHL related to COVID-19. More frequent use of websites of public bodies (OR = 1.7; 95% CI = 1.1; 2.5) increased the odds of reporting sufficient DHL. CONCLUSION DHL is associated with university students' online information-seeking behavior in the time of COVID-19. From a community and public health perspective, programs aiming at improving DHL should be highlighted.

Abstract
BACKGROUND AND OBJECTIVES Resistant lupus nephritis (LN) has been associated with the persistence of long-lived plasma cells. Preliminary studies identified bortezomib as a potential treatment option for patients with refractory LN. The aim of this study was to analyze the efficacy and safety of bortezomib in the treatment of severe refractory LN. METHODS This retrospective study included 12 female patients diagnosed for the first time with class IV or IV/V LN with acute or rapidly progressive kidney injury (n = 11) and/or severe nephrotic syndrome (n = 1) who showed resistance to induction therapy with cyclophosphamide, steroids, mycophenolate, and rituximab, and were treated with either intravenous or subcutaneous bortezomib plus intravenous dexamethasone. RESULTS All patients with acute or rapidly progressive kidney injury showed a significant reduction in both biochemical and immunological activity after a mean of 6 (minimum 5, maximum 7) weekly cycles of bortezomib regimen, with a significant increase in C3 levels and a significant decrease of anti-ds DNA antibody titers, Systemic Lupus Erythematosus Disease Activity Index score, serum creatinine, and proteinuria. One patient (8.3%) achieved a complete response, and 10 patients (83.4%) achieved a partial response. During follow-up, all these patients maintained partial responses under treatment with mycophenolate and low-dose glucocorticoids. The patient with refractory nephrotic syndrome showed a partial response but relapsed 11 months after the end of bortezomib treatment and was resistant to treatment. A significant decrease in serum IgG levels after initiation of bortezomib treatment was observed in all patients, five of them (41.6%) showed hypogammaglobulinemia (<500 mg/dl), but no patient suffered from opportunistic infections; in only two patients (16.6%) hypogammaglobulinemia persisted at the end of follow-up. Two patients (16.6%) suffered from sensory neuropathy, which led to bortezomib treatment discontinuation. CONCLUSIONS Bortezomib may be an effective option for refractory LN, but close monitoring must be performed for possible adverse events such as peripheral neuropathy and hypogammaglobulinemia.

Abstract
Within the last two decades, several high-impact viruses have emerged in the global swine population, including porcine reproductive and respiratory syndrome virus (PRRSV). In Uruguay, the more recent serological survey for PRRSV and other notifiable diseases such as Aujeszky's disease virus (ADV) and classical swine fever virus (CSFV) dated from year 2000. The main purpose of this study was to update our information on the infection status of PRRSV, ADV and CSFV in Uruguayan pig herds, in order to keep informed about the epidemiological situation of these notifiable infections in the country. For serological testing, a total of 524 swine serum samples collected during the period 2014-2016 were assayed by commercial ELISAs. Our results revealed the (unexpected) presence of PRRSV antibodies in Uruguayan domestic swine herds and confirmed the absence of ADV and CSFV antibodies in all of the assessed samples. Following such initial finding, PRRSV antibodies were further investigated in 23 retrospective samples collected during 2010-2014. Thirteen of these 23 samples resulted seropositive. Subsequently, a molecular detection approach in frozen serum samples was implemented to confirm PRRSV infection, and viral RNA was identified by reverse transcription-nested polymerase chain reaction (RT-nPCR). Fourteen of 86 evaluated 2014-2016 samples resulted positive for viral RNA, while molecular analysis of four retrospective samples also revealed the presence of PRRSV type 2. Viral isolation of selected samples was carried out in porcine alveolar macrophages (PAM) and MARC 145 simian kidney cells, and the virus identity was confirmed by cytopathic effect (CPE) and immunofluorescence assay (IFA) using specific monoclonal antibodies for PRRSV nucleocapsid. Data reported here evidence for the first time the circulation of PRRSV type 2 in Uruguay, and retrospective serology results suggest that the virus has been infecting pigs in this country at least since 2011.

Abstract
Vesicles composed of block copolymers (i.e., polymersomes) are one of the most versatile nano-carriers for medical purposes due to their tuneable physicochemical properties and the possibility to encapsulate simultaneously hydrophobic and hydrophilic substances, allowing, for instance, the combination of therapy and imaging. In cancer treatment, these vesicles need to remain long enough in the blood stream to be sufficiently taken up by tumors. Here, we have investigated the biodistribution and the pharmacokinetics of polymersomes, composed of poly(butadiene-b-ethylene oxide) having dimensions around 80 nm. The polymersomes have been radiolabeled with ¹¹¹In via the so-called active loading method achieving a loading efficiency of 92.9 ± 0.9% with radionuclide retention in mouse serum of more than 95% at 24 h. The optimized ¹¹¹In containing polymersomes have been intravenously administered in healthy and tumor bearing mice for pharmacokinetic determination using microSPECT (Single Photon Emission Computed Tomography). In healthy mice these polymersomes have been found to exhibit relatively long blood circulation (> 6 h), low liver uptake (6 ± 1.5%ID/g, 48 h p.i.) and elevated spleen uptake (188 ± 30%ID/g). The blood circulation in tumor bearing mice is dramatically reduced (< 1.5 h) most likely due to elevated splenic filtration, clearly indicating the importance of in vivo studies in diseased mice. Finally, the polymersomes have been injected subcutaneously in tumor bearing mice revealing retention of 77% in the mice, primarily accumulated at the site of injection, up to 48 hours after administration.

Abstract
The enhanced extrinsic coagulation in response to inflammation could contribute to disseminated intravascular coagulation, often manifesting cardiovascular complications. The complex mechanism remains unclear and effective management is not well established. The ability of protamine to offset bacterial endotoxin (LPS)-induced tissue factor (TF)-initiated extrinsic coagulation was demonstrated in human peripheral blood monocytes and cultured human leukaemia THP-1 monocytes, which was consistent with the inhibition of rabbit brain thromboplastin (rbTF) procoagulant activity in a cell-free in vitro model. Protamine significantly prolonged prothrombin time, further confirming the downregulation of the extrinsic pathway. However, thrombin time remained unaltered. Chromogenic assays were performed to dissect the extrinsic pathway, identifying inhibitory site(s). Protamine significantly inhibited factor VII (FVII) activation but not the dissected FX activation. The amidolytic activities of FVIIa and FXa were unaffected. The inhibited FVII activation in the presence of protamine was confirmed by the diminished FVIIa formation on Western blot analyses. Protamine preferentially inhibited TF-catalysed FVII activation, downregulating the extrinsic cascade. Protamine could be of anticoagulant significance in the management of the extrinsic hypercoagulation.

Abstract
BACKGROUND Hypercoagulability is one of the commonly exhibited endotoxemia septic symptoms; it could contribute to the manifestation of disseminated intravascular coagulation presenting threats to cardiovascular functions. The underlying mechanism, however, remains largely complex and unknown. OBJECTIVES We herein determine whether bacterial endotoxin (LPS) upregulates the activities of clotting factors in plasma, contributing to extrinsic hypercoagulation. Compound 48/80 (48/80) is also tested for its ability to suppress hypercoagulation. METHODS In an in vitro infection model, we exposed whole blood to LPS (Escherichia coli 0111:B04; 100 ng/ml) for 2 h. Thrombin time (TT), prothrombin time (PT), and the activities of clotting factors ( FVII, FIX, FX ) in plasma contributing to the extrinsic coagulation were determined. Peripheral blood monocytes were isolated from Histoplaque 1077 gradient centrifugation, and the procoagulant activity was determined by a single-stage clotting assay on a Fibrometer. RESULTS LPS drastically activated monocytic procoagulant activity which was defined as tissue factor (TF) activity, whereas LPS had no effect on TT, PT, and the activities of clotting factors in plasma. 48/80 not only instantaneously offset LPS-induced monocytic TF activation, but also significantly inhibited PT including the activities of clotting factors (FVII, FIX, and FX) in plasma, whereas TT remained unaffected. CONCLUSIONS Monocytic TF activation was solely responsible for the extrinsic hypercoagulation in response to LPS. 48/80 effectively suppressed LPS-induced monocyticTF-initiated extrinsic coagulation at multiple sites, possibly presenting a new therapy for an instantaneous relief of hypercoagulation under septic conditions.

Abstract
In paralytic shellfish poisoning a mollusc contaminated with a toxin (saxitoxin) causes a potentially lethal disease, clinically characterised by gastrointestinal and neurological symptoms, of which possible respiratory depression is the most serious. The toxin acts by blocking the sodium channels. We report 9 Portuguese patients with this disease. The mollusc was identified as Mytilus edulis, contaminated with the dinoflagellate Gymnodinium catenatum, and the toxin saxitoxin. Our patients had a benign clinical course with cerebellar ataxia as the most severe neurological impairment. Eight out of 9 patients had neurophysiological investigations, the largest number so far reported. Motor and sensory conduction velocities and amplitudes were normal. The proximal conduction times, as assessed by F waves, showed delayed conduction and decreased frequency, which returned to normal in few weeks. The somatosensory evoked potentials confirmed normal peripheral and central sensory conduction. The rich vascular supply at root level of the sodium channels of the proximal motor nerves may explain the greater vulnerability to toxin damage. The typically transient and quickly reversible nerve dysfunction caused by ion channel blockade is reported.
