RESUMEN
OBJECTIVE: This study aimed to evaluate inflammatory biomarkers in patients undergoing peritoneal dialysis and investigate their association with all-cause mortality or transfer to hemodialysis. METHODS: This prospective cohort study included 43 patients undergoing peritoneal dialysis. Plasma levels of cytokines were measured using flow cytometry and capture enzyme-linked immunosorbent assay. Biomarkers were categorized based on their respective median values. Survival analysis was conducted using the Kaplan-Meier estimator, considering two outcomes: all-cause mortality and transfer to hemodialysis. RESULTS: After adjusting for confounding factors, plasma levels above the median of the levels of CCL2 and plasma, as well as below the median of TNF-α, and the median of dialysate IL-17 levels, were associated with an increased risk of experiencing the specified outcomes after approximately 16 months of follow-up. CONCLUSION: These findings suggest that inflammatory biomarkers may be a valuable tool for predicting all-cause mortality and transfer to hemodialysis in patients undergoing peritoneal dialysis.

Ornithine transcarbamylase (OTC) deficiency is the most common genetic disorder of the urea cycle. These disorders are characterized by an inability to metabolize ammonia into urea, leading to hyperammonemia with variable physiological consequences and presenting important anesthetic challenges, especially the perioperative prevention of hyperammonemia and management of its consequences, should it occur. Idiopathic scoliosis (IS) is the most common spinal deformity requiring surgical treatment. This paper presents the case of a 16-year-old female with OTC deficiency who underwent spinal fusion for IS. The chosen anesthetic strategy was combined anesthesia with total intravenous general anesthesia using target-controlled infusion pumps, an erector spinae plane block (ESPB), and a multi-pronged approach to ensure metabolic control while avoiding hyperammonemia. The existing literature regarding major surgery in patients with OTC deficiency is sparse, and this paper provides one of the first case reports of a scoliosis correction surgery, as well as one of the first descriptions of prolonged propofol infusion and locoregional anesthesia with an erector spinae plane block in this context.
RESUMEN
Extracorporeal membrane oxygenation (ECMO) provides a bypass of the lungs, ensuring blood oxygenation and carbon dioxide removal in cases of respiratory failure. The nature of the device itself creates many perioperative challenges, including fluid management and the management of anticoagulation. Surgery via the posterior approach for an unstable spinal fracture requiring the ventral decubitus position comes with its own set of difficulties, among which are the need for stability and craniocaudal alignment when rotating the patient, the risk of increased abdominal pressure, and the damage to vulnerable soft tissues like the eyes, nose, and others. The combination of these two situations creates a synergistic effect, which adds to the difficulty of the management of the situation and requires a personalized, multidisciplinary approach. We present a case of a critical trauma patient who was on venovenous ECMO as a consequence of refractory respiratory hypoxemia with an unstable mid-thoracic spinal fracture requiring surgical intervention via the posterior approach (demanding intra-operative ventral decubitus).
RESUMEN
The present study was designed as an exploratory investigation to characterize the overall profile of chemokines, growth factors, and pro-inflammatory/regulatory cytokines during acute DENV infection according to DENV-1, DENV-2, DENV-4 serotypes and age: children: <1-10-year-old (yo); adolescents:11-20 yo; adults 21-40 yo; and older adults: 41-75 yo. The levels of soluble immunemediators were measured in serum by high-throughput microbeads array in 636 subjects including 317 DENV-infected and 319 age-matching non-infected control (NI). Overall, most soluble mediators were increased in DENV-infected patients as compared to NI group regardless of age and DENV serotype, with high magnitude order of increase for CCL2, CXCL10, IL-1ß, IFN-γ, IL1-Ra (fold change >3x), except PDGF in which no fold change was observed. Moreover, despite the age ranges, DENV-1 and DENV-4 presented increased levels of VEGF, IL-6, and TNF-α in serum but decreased levels of PDGF, while DENV-2 exhibited increased levels of CXCL8, CCL4, and IL-12. Noteworthy was that DENV-2 showed increased levels of IL-12, IL-15, IL-17, IL-4, IL-9, and IL-13, and maintained an unaltered levels of PDGF at younger ages (<1-10 yo and 11-20 yo), whereas in older ages (21-40 yo and 41-75 yo), the results showed increased levels of CCL2, IL-6, and TNF-α, but lower levels of PDGF. In general, DENV infection at younger age groups exhibited more complex network immunoclusters as compared to older age groups. Multivariate analysis revealed a clustering of DENV cases according to age for a set of soluble mediators especially in subjects infected with DENV-2 serotype. Altogether, our findings demonstrate that the profile of circulating soluble mediators differs substantially in acute DENV according to age and DENV serotypes suggesting the participation of serotype-associated immune response, which may represent a potential target for development of therapeutics and could be used to assist medical directive for precise clinical management of severe cases.

Introdução: Em pacientes em enfermarias, eventos adversos evitáveis podem decorrer de deterioração clínica despercebida, frequentemente antecedida por alterações nos sinais vitais, fornecendo oportunidade para intervenção precoce. A adoção de Equipe de Resposta Rápida (ERR) pode melhorar esse desfecho, porém é altamente dependente do monitoramento dos parâmetros fisiológicos e da notificação da ERR. Objetivo: Avaliar a qualidade das informações em prontuários e da resposta assistencial a pacientes em enfermarias com agravamento do estado clínico, resultando em óbito ou transferência para UTI em um Hospital Universitário e fornecer dados para comparação de resultados após implantação da ERR. Material e Métodos: Estudo documental retrospectivo, entre junho de 2013 e julho de 2014, em 128 prontuários de pacientes com piora clínica que resultou em óbito ou admissão em UTI ("evento"). Foram coletados os parâmetros fisiológicos, a pontuação no Escore para Alerta Precoce e o Plano de Ação registrado em 11 momentos que antecederam o "evento", resultando em 11 escores. A relação entre a pontuação do Escore de Alerta Precoce e a execução do Plano de Ação foi classificada como "adequada", "inadequada" ou "ausente". Resultados: Quanto mais se afastava momento de ocorrência do "evento", maior foi o número de dados faltantes, ocasionando Escores de Alerta Precoce não calculáveis. O número de casos adequados foi menor quanto mais distante estava o "evento" do momento da aferição dos parâmetros fisiológicos. Conclusão: Os tempos de resposta foram inadequados ao Plano de Ação. A falha em socorrer pacientes em deterioração clínica é complexa e multifatorial, mas acredita-se que no presente relato isto se deveu, pelo menos em parte, à anotação inadequada dos parâmetros fisiológicos. Esforços devem ser envidados no sentido de reforçar a importância do registro dos parâmetros fisiológicos, de reconhecer, de intervir e de comunicar agravos, essenciais para o correto funcionamento das alças aferente e eferentes das ERR.
Introduction: Preventable adverse events may result from unnoticed clinical deterioration in inpatients, which are often preceded by changes in warning signs, providing an opportunity for early intervention. The adoption of the Rapid Response Team (ERR) can improve the outcome; however, it is highly dependent on monitoring of the physiological parameters and on notification of the ERR. Objective: To evaluate the quality of information in medical records and the care response to patients in wards with worsening of the clinical status, which resulting in death or transfer to the ICU in a University Hospital and provide data for future comparison of results after ERR deployment. Material and Methods: Documentary retrospective study, between June 2013 and July 2014, of 128 medical records of patients with clinical worsening who died in death or admission to the ICU ("event"). The physiological parameters, the score on the Early Warning Score and the Action Plan recorded in 11 moments that preceded the "event" were collected, resulting in 11 scores. The relationship between the Early Warning Score and Action Plan execution was classified as "adequate", "inadequate" or "absent". Results: The further away from the moment of occurrence of the "event", greater the number of missing data, causing non- calculable Early Warning Scores. The number of adequate cases was smaller the further away the "event" was from the moment of measurement of the physiological parameters. Conclusion: Response times were inadequate to the Action Plan. Failure to rescue patients in the clinic is a complex and multifactorial, but it is believed that in the present report this was due, at least in part, to inadequate recording of physiological parameters. Efforts should be made to reinforce the importance of recording physiological parameters, recognizing, intervening, and communicating injuries, which are essential for the correct functioning of the afferent and efferent loops of the ERR.
RESUMEN
Background: Central nervous system (CNS) infections are important causes of mortality and morbidity in children, and they are related to severe problems such as hearing loss, neurological sequelae, and death. The objective was to describe clinical and laboratory exam profiles of children who were diagnosed with CNS infections. Methods: We conducted a cross-sectional study based on medical records, which included pediatric patients aged from 3 months to 15 years, with a clinical suspicion of CNS infection between January 2014 to December 2019. The pathogens were confirmed in cerebrospinal fluid (CSF) samples using Gram staining, cell culture, molecular diagnostics (PCR and qPCR), and serology. Results: Out of the 689 enrolled patients, 108 (15.6%) had laboratory-confirmed infections in CSF. The most common bacterial pathogens isolated from the culture were Neisseria meningitidis serogroup C in 19, Streptococcus pneumoniae in 11, and Haemophilus influenzae in seven samples. The viruses identified were Enterovirus, Cytomegalovirus, Varicella-zoster virus, Epstein-Barr virus, and arbovirus. No patient was found to be positive for Herpes simplex virus 1 and 2. Patients with viral infections showed altered levels of consciousness (p = 0.001) when compared to bacterial infections. Conclusion: This study shows the presence of important vaccine-preventable pathogens, and different families of viruses causing CNS infections in the pediatric patients of Manaus.

Background: Opportunistic infections in the central nervous system (CNS) of people with HIV/AIDS (PLWHA) remain significant contributors to morbidity and mortality, especially in resource-limited scenarios. Diagnosing these infections can be challenging, as brain imaging is non-specific and expensive. Therefore, molecular analysis of cerebrospinal fluid (CSF) may offer a more accurate and affordable method for diagnosing pathogens. Methods: We conducted extensive real-time PCR testing (qPCR) on CSF to evaluate etiological agents in PLWHA with neurological manifestations. Primers targeting DNA from specific pathogens, including cytomegalovirus (CMV), herpes simplex virus (HSV), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), John Cunningham virus (JCV), Toxoplasma gondii, and human T-lymphotropic virus types 1 and 2 (HTLV-1 and HTLV-2), were used. Results: Cerebrospinal fluid samples revealed 90 pathogens (36.7%). Toxoplasma gondii was the most frequently detected pathogen, found in 22 samples (30.5%). Other pathogens included Cryptococcus sp. (7.7%), EBV (5.3%), CMV, VZV, and JCV (4.0% each). Conclusion: Despite antiretroviral therapy and medical follow-up, opportunistic central nervous system infections remain frequent in PLWHA. Herpesviruses are commonly detected, but T. gondii is the most prevalent opportunistic pathogen in our study population. Therefore, molecular diagnosis is a crucial tool for identifying opportunistic infections, even in patients undergoing treatment.
RESUMEN
The American Society of Anesthesiologists (ASA) defines a difficult airway as a clinical situation in which a physician who is trained in anesthesiology experiences difficulty or fails in either face mask ventilation, laryngoscopy, using a supraglottic airway, tracheal intubation, extubation, or front-of-neck airway. Classically, this has been defined in relation to anatomic factors, but the concept of a physiologically difficult airway has been growing in relevance, in which physiologic factors, such as hypoxemia and hypercapnia, act to reduce safe apnea times. The case reports on a trauma patient with an unstable thoracic vertebral fracture requiring correction via the posterior approach. Our patient had multiple anatomical difficult airway predictors, namely, a short neck, greatly limited neck mobility, and a Mallampati class IV airway, among others, and multiple physiological difficult airway predictors, such as a baseline hypoxemic respiratory failure and severe sleep apnea, in addition to the restrictions on mobility imposed by the fracture itself. We describe a successful perioxygenation strategy, using high-flow nasal oxygen (HFNO) during the preoxygenation, intubation, extubation, and post-anesthesia care phases, and with an awake fiberoptic intubation technique for securing the airway.

RESUMEN
BACKGROUND: In the clinical course of diseases such as arboviruses, skin rashes may appear, as is often seen in other infectious diseases. The aim of this study was to estimate the prevalence of arboviruses and other infectious causes of skin rash in a tertiary health unit in Manaus, Amazonas state, Western Brazilian Amazon. METHODOLOGY/PRINCIPAL FINDINGS: This was a cross-sectional study of patients presenting with rash who sought care at Fundação de Medicina Tropical Dr. Heitor Vieira Dourado (FMT-HVD) from February 2018 to May 2019. Individuals of either gender, aged over 18 years, were invited to participate voluntarily. Infection by Zika virus (ZIKV), dengue virus (DENV), chikungunya virus (CHIKV), Mayaro virus (MAYV), Oropouche virus (OROV) and measles was evaluated using RT-qPCR (real-time polymerase chain reaction). Immunodiagnostic tests for EBV, CMV, HIV, syphilis, rubella and measles were also performed. A total of 340 participants were included, most were female (228, 67.1%) with an average age of 36.5 years (SD ± 12.2 years). The highest prevalence was of ZIKV monoinfections (65.3%, 222/340), followed by DENV (0.9%, 3/340) and CHIKV infection (0.3%, 1/340). No cases of MAYV, OROV or rubella were found. Other causes of skin rash were detected: measles (2.9%, 10/340), parvovirus B19 (0.9% 3/340), HIV (0.3%, 1/340) and syphilis 0.6% (2/340). The co-infections identified were ZIKV+HIV (0.3%, 1/340), ZIKV+measles (0.3%, 1/340), ZIKV+parvovirus B19 (0.3%, 1/340), ZIKV+EBV (0.3%, 1/340), EBV+parvovirus B19 (0.3%, 1/340), CMV+parvovirus B19 (0.6%, 2/340), CMV+syphilis (0.3%, 1/340), ZIKV+EBV+parvovirus B19 (0.3%, 1/340) and CMV+EBV+parvovirus B19 (0.9%, 3/340). Approximately one quarter of patients had no defined cause for their skin rash (25.3%, 86/340). CONCLUSIONS: Despite the benign clinical evolution of most of the diseases diagnosed in this series of cases, syndromic surveillance of diseases such as syphilis and HIV are of utmost importance. Periodic serosurveillance might also aid in evaluating the trends of endemic diseases and eventual outbreaks.

Introduction: Post-streptococcal glomerulonephritis (PSGN) has a good prognosis in children, but few studies have evaluated the long-term renal outcomes in adults with PSGN. Methods: In a follow-up study, 47 predominantly adult patients with PSGN due to group C Streptococcus zooepidemicus were reassessed 20 years after an outbreak in Nova Serrana, Brazil. We evaluated clinical characteristics, renal outcomes, and the trajectory of the estimated glomerular filtration rate (eGFR) by the creatinine-based chronic kidney disease-epidemiology collaboration equation from 5 follow-up assessments. Logistic regression and mixed-effects regression were used in the analysis. Results: After 20 years, the participants' mean age was 56.6±15.1 years. Thirty-four (72%) patients had hypertension, 21 (44.7%) had eGFR <60 ml/min per 1.73 m2, 8 of 43 (18.6%) had urine protein-to-creatinine ratio >150 mg/g, and 25 (53%) had CKD (low eGFR and/or increased proteinuria). Increasing age was associated with CKD (odds ratio: 1.07; 95% confidence interval [CI]: 1.02-1.13; P = 0.011) in multivariate analysis. The mean eGFR decline in the last 11 years of follow-up was -3.2 ml/min per 1.73 m2 per year (95% CI: -3.7 to -2.7). Older age at baseline (coefficient -1.05 ml/min per 1.73 m2 per year; 95% CI -1.28 to -0.81; P < 0.001), and hypertension 5 years after the outbreak (coefficient -7.78 ml/min/1.73 m2; 95% CI -14.67 to -0.78; P = 0.027) were associated with lower eGFR during the whole study period. Conclusion: There was a marked worsening of renal function and a high prevalence of CKD and hypertension after 20 years of PSGN outbreak. Long-term follow-up is warranted after PSGN, especially among older patients.

Walled-off pancreatic necrosis (WOPN) is one of the local complications of acute pancreatitis (AP). Several interventional techniques have been developed over the last few years. The purpose of this narrative review is to explore such methodologies, with specific focus on endoscopic drainage and direct endoscopic necrosectomy (DEN), through evaluation of their indications and timing for intervention. Findings indicated how, after the introduction of lumen-apposing metal stents (LAMS), DEN is becoming the favorite technique to treat WOPN, especially when large solid debris or infection are present. Additionally, DEN is associated with a lower adverse events rate and hospital stay, and with improved clinical outcome.

In this pilot program of low-dose computed tomography (LDCT) for the screening of lung cancer (LC) in a targeted population of people with HIV (PWH), its prevalence was 3.6%; the number needed to screen in order to detect one case of lung cancer was 28, clearly outweighing the risks associated with lung cancer screening. While data from additional cohorts with longitudinal measurements are needed, PWH are a target population for lung cancer screening with LDCT.

Abstract Introduction: Progressive structural changes in the peritoneal membrane occur over the course of treatment in peritoneal dialysis (PD), resulting in an increase in cytokines such as CCL2 and structural changes in peritoneal membrane triggering an increase in CA-125 in dialysate, which reflects a probable local inflammatory process, with possible loss of mesothelial cells. Thus, the current study aimed to evaluate the association between plasma and CCL2 and CA-125 dialysate levels in patients undergoing PD. Methods: Cross-sectional study was conducted with 41 patients undergoing PD. The assessments of CA-125 and CCL2 levels were performed using a capture ELISA. Correlations were estimated using Spearman's correlation and the investigation of the association between the explanatory variables (CCL2) and response variable (CA-125) was done for crude ratio of arithmetic means and adjusted utilizing generalized linear models. Results: A moderate positive correlation was observed between the levels of CA-125 and CCL2 in the dialysate (rho = 0.696). A statistically significant association was found between the levels in the CCL2 and CA-125 dialysate (RoM=1.31; CI = 1.20-1.43), which remained after adjustment for age (RoM = 1.31; CI=1.19-1.44) and for time in months of PD (RoM=1.34, CI=1.22-1.48). Conclusion: The association of CA-125 levels with CCL2 in the dialysate may indicate that the local inflammatory process leads to temporary or definitive changes in peritoneal membrane. A better understanding of this pathogenesis could contribute to the discovery of new inflammatory biomarkers.
Resumo Introdução: Alterações estruturais progressivas na membrana peritoneal ocorrem no decorrer do tratamento em diálise peritoneal (DP), resultando em um aumento de citocinas como CCL2 e alterações estruturais na membrana peritoneal desencadeando um aumento de CA-125 no dialisato, o que reflete um provável processo inflamatório local, com possível perda de células mesoteliais. Assim, o presente estudo teve como objetivo avaliar a associação entre CCL2 e CA-125 no plasma e no dialisato de pacientes submetidos à DP. Métodos: Foi realizado um estudo transversal com 41 pacientes submetidos à DP. As avaliações dos níveis de CA-125 e CCL2 foram realizadas utilizando ELISA de captura. As correlações foram estimadas usando a correlação de Spearman, e a investigação da associação entre as variáveis explicativas (CCL2) e a variável resposta (CA-125) foi feita pela razão bruta das médias aritméticas e ajustada utilizando modelos lineares generalizados. Resultados: Foi observada uma correlação positiva moderada entre os níveis de CA-125 e CCL2 no dialisato (rho = 0,696). Foi encontrada uma associação estatisticamente significativa entre os níveis no dialisato de CCL2 e CA-125 (RoM=1,31; IC = 1,20-1,43), que permaneceu após ajuste por idade (RoM = 1,31; IC=1,19-1,44) e pelo tempo de DP em meses (RoM=1,34, IC=1,22-1,48). Conclusão: A associação dos níveis de CA-125 com CCL2 no dialisato pode indicar que o processo inflamatório local leva a alterações temporárias ou definitivas na membrana peritoneal. Uma melhor compreensão desta patogênese pode contribuir para a descoberta de novos biomarcadores inflamatórios.

BACKGROUND AND AIMS: The COVID-19 pandemic has led to a deep reorganization of hospital services including inflammatory bowel disease (IBD) units. In this situation, conversion of in-person routine follow-up visits into phone consultations might be necessary. Here we explored the feasibility of using the validated Crohn's Disease (CD) or Ulcerative Colitis (UC) Patient-Reported Outcomes Signs and Symptoms (CD- and UC-PRO/SS) to collect data about abdominal symptoms (abdominal/S) and bowel signs and symptoms (bowel/SS) remotely. METHODS: CD- and UC-PRO/SS were collected during phone consultations and compared among patients with active and inactive disease. The effectiveness of therapeutic intervention in patients with active disease was assessed by PRO/SS variation. RESULTS: Twenty-one CD and 56 UC patients were evaluated by phone. Six (28.6%) CD and 15 (26.8%) UC patients were considered to have active disease. In CD the bowel/SS but not the abdominal/S module was significantly higher in active patients (mean bowel/SS 2.50 [SE ± 0.44] active vs 0.76 [SE ± 0.18] remission, p = 0.008, AUC 0.87; mean abdominal/S 1.11 [SE ± 0.38] active vs 0.24 [SE ± 0.13] remission, p = 0.066). UC-PRO/SS measures were significantly higher in active patients as compared to patients in remission (median bowel/SS 1.63 [SE ± 0.24] active vs 0.33 [SE ± 0.04] remission; p < 0.0001, AUC 0.91; mean abdominal/S 1.03 [SE ± 0.24] vs 0.37 [SE ± 0.12]; p = 0.009, AUC 0.71). Therapy was escalated in 12 patients (3 CD and 9 UC) due to disease relapse. Therapy escalation resulted in the reduction of PRO/SS as evaluated at the subsequent phone consultation. CONCLUSIONS: PRO/SS might represent a feasible tool to evaluate disease activity and therapy outcome in IBD patients during periods of limited access to outpatient clinics.

O objetivo deste estudo foi analisar as possíveis relações entre a variável antropométrica comprimento dos membros inferiores e de passada na marcha, com valores naturais e normalizados, em velocidade auto-selecionada e acrescida de 50%, em indivíduos adultos jovens. Foram avaliados 32 sujeitos hígidos adultos entre 18-25 anos. Os deslocamentos corporais nas duas velocidades foram registrados através da técnica de cineantropometria, utilizando o software Skillspector® para quantificar o comprimento da passada entre as médias dos dados normalizadas e não-normalizadas, do segmento direito e do segmento esquerdo. A comparação entre os valores médios das passadas normalizadas e não-normalizadas, nas diferentes velocidades, foi realizada por meio do teste t student (p < 0,05), assim como o grau de associação entre o comprimento da passada e o comprimento do membro inferior, realizada pelo teste de correlação de Pearson (p < 0,05). Sendo assim, nosso estudo constatou uma correlação positiva entre as variáveis estudadas, nas duas velocidades e, uma diferença entre a passada com dados normalizados e não normalizados, em ambas as velocidades.

The aim of this study was to analyze the possible relationships between the anthropometric variable length of the lower limbs and gait stride, with natural and normalized values, at self-selected speed and increased by 50%, in young adult individuals. 32 healthy adult subjects aged 18-25 years were evaluated. Body movements at both speeds were recorded using the kinanthropometry technique, using the Skillspector® software to quantify the stride length between the normalized and nonnormalized data averages for the right and left segments. The comparison between the mean values of normalized and non-normalized strides, at different speeds, was performed using the Student t test (p < 0.05), as well as the degree of association between stride length and lower limb length, performed by the Pearson correlation test (p < 0.05). Thus, our study found a positive correlation between the variables studied, at both speeds, and a difference between the stride with normalized and non-normalized data, at both speeds. (AU)

BACKGROUND AND AIMS: A similar course of COVID-19 in patients with inflammatory bowel diseases [IBD] and in the general population has been reported. However, disease prevalence in IBD patients is presently unknown. In this prospective observational study, we aimed at determining SARS-CoV2 infection prevalence in IBD patients treated with biologic therapy. METHODS: From IBD patients under biologic therapy and recruited from three different locations in Italy and Germany, 354 sera were evaluated for antibody presence by RBD ELISA. Control groups were: i] age-matched healthy subjects tested in the same time period in Milan, Italy; ii] healthy subjects collected in the pre-COVID era; iii] IBD patients under biologic therapy collected in the pre-COVID era. RESULTS: Eight out of 354 patients tested positive for the anti-RBD-SARS-CoV2 IgG antibody [prevalence 2.3%]. The percentage of IgG-positive patients among those recruited from Milan was significantly higher than among those recruited from other locations [prevalence 5.4% vs 0.4%, pâ <0.005]. IgG-positive patients reported a significantly higher incidence of fever, anosmia, and ageusia, and were more likely to have entered into close contact with COVID-19-positive subjects before the study enrolment. CONCLUSIONS: Seroprevalence of SARS-CoV2 in IBD patients treated with biologic therapy reflects values measured in the local general population. Specific symptoms and contact history with SARS-CoV2-infected individuals strongly increase the likelihood of SARS-CoV2 seropositivity.
