- Plasmid-mediated mcr-1 in carbapenem-susceptible Escherichia coli ST156 causing a blood infection: an unnoticeable spread of colistin resistance in Brazil?(2017) ROSSI, Flavia; GIRARDELLO, Raquel; MORAIS, Carlos; CURY, Ana Paula; MARTINS, Layla Farage; SILVA, Aline Maria da; ABDALA, Edson; SETUBAL, Joao Carlos; DUARTE, Alberto Jose da SilvaOBJECTIVE: We describe an IncX4 pHC891/16mcr plasmid carrying mcr-1 in a colistin-resistant and carbapenem-susceptible E. coli isolate (HC891/16), ST156, which caused a blood infection in a Brazilian patient with gallbladder adenocarcinoma. METHODS: Strain HC891/16 was subjected to whole genome sequencing using the MiSeq Platform (Illumina, Inc., USA). Assembly was performed using Mira and ABACAS. RESULTS: The isolates showed resistance only to ciprofloxacin, ampicillin and cefoxitin, and whole-genome sequencing revealed the presence of aac(6')Ib-cr and bla(TEM1). CONCLUSION: Our findings warn of the possible silent dissemination of colistin resistance by carbapenem-susceptible mcr-1 producers, as colistin susceptibility is commonly tested only among carbapenem-resistant isolates.
- Association between muscle strength and the cardiopulmonary status of individuals living with HIV/AIDS(2013) RASO, Vagner; SHEPHARD, Roy J.; CASSEB, Jorge; DUARTE, Alberto Jose da Silva; SILVA, Paulo Roberto Santos; GREVE, Julia Maria D'AndreaOBJECTIVE: The purpose of this study was to compare aerobic function [ anaerobic threshold (%(V) over dotO(2)-AT), respiratory compensation point (%(V) over dotO(2)-RCP) and peak oxygen uptake ((V) over dotO(2peak))] between physically active patients with HIV/AIDS and matched controls and to examine associations between disease status, poor muscle strength, depression (as estimated by the profile of mood states questionnaire) and the aerobic performance of patients. METHODS: Progressive treadmill test data for %(V) over dotO(2)-AT (V-slope method), RCP and ((V) over dotO(2peak)) were compared between 39 male patients with HIV/AIDS (age 40.6 +/- 1.4 years) and 28 male controls (age 44.4 +/- 2.1 years) drawn from the same community and matched for habitual physical activity. Within-patient data were also examined in relation to CD4(+) counts (nadir and current data) and peak isokinetic knee torque. RESULTS: AT, RCP and ((V) over dotO(2peak)) values were generally similar for patients and controls. Within the patient sample, binary classification suggested that AT, RCP and ((V) over dotO(2peak)) values were not associated with either the nadir or current CD4(+) count, but treadmill test variables were positively associated with peak isokinetic knee torque. CONCLUSION: The aerobic performance of physically active patients with HIV/AIDS is generally well conserved. Nevertheless, poor muscle strength is observed in some HIV/AIDS patients, which is associated with lower anaerobic power and ((V) over dotO(2peak)), suggesting the possibility of enhancing the aerobic performance of patients with weak muscles through appropriate muscle-strengthening activities.
- Persistent symptoms and decreased health-related quality of life after symptomatic pediatric COVID-19: A prospective study in a Latin American tertiary hospital (vol 76, e3511, 2021)(2022) FINK, Thais T.; MARQUES, Heloisa H.

- Differences in children and adolescents with SARS-CoV-2 infection: a cohort study in a Brazilian tertiary referral hospital(2021) MARQUES, Heloisa Helena de Sousa; PEREIRA, Maria Fernanda Badue; SANTOS, Angelica Carreira dos; FINK, Thais Toledo; PAULA, Camila Sanson Yoshino de; LITVINOV, Nadia; SCHVARTSMAN, Claudio; DELGADO, Artur Figueiredo; GIBELLI, Maria Augusta Bento Cicaroni; CARVALHOL, Werther Brunow de; ODONE FILHO, Vicente; TANNURI, Uenis; CARNEIRO-SAMPAIO, Magda; GRISI, Sandra; DUARTE, Alberto Jose da Silva; ANTONANGELO, Leila; FRANCISCO, Rossana Pucineli Vieira; OKAY, Thelma Suely; BATISTTELLA, Linamara Rizzo; CARVALHO, Carlos Roberto Ribeiro de; BRENTANI, Alexandra Valeria Maria; SILVA, Clovis ArturOBJECTIVES: To compare demographic/clinical/laboratory/treatments and outcomes among children and adolescents with laboratory-confirmed coronavirus disease 2019 (COVID-19). METHODS: This was a cross-sectional study that included patients diagnosed with pediatric COVID-19 (aged <18 years) between April 11, 2020 and April 22, 2021. During this period, 102/5,951 (1.7%) of all admissions occurred in neonates, children, and adolescents. Furthermore, 3,962 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection samples were processed in patients aged <18 years, and laboratory-confirmed COVID19 occurred in 155 (4%) inpatients and outpatients. Six/155 pediatric patients were excluded from the study. Therefore, the final group included 149 children and adolescents (n=97 inpatients and 52 outpatients) with positive SARS-CoV-2 results. RESULTS: The frequencies of sore throat, anosmia, dysgeusia, headache, myalgia, nausea, lymphopenia, pre-existing chronic conditions, immunosuppressive conditions, and autoimmune diseases were significantly reduced in children and adolescents (p < 0.05). Likewise, the frequencies of enoxaparin use (p=0.037), current immunosuppressant use (p=0.008), vasoactive agents (p=0.045), arterial hypotension (p <0.001), and shock (p=0.024) were significantly lower in children than in adolescents. Logistic regression analysis showed that adolescents with laboratory-confirmed COVID-19 had increased odds ratios (ORs) for sore throat (OR 13.054; 95% confidence interval [CI] 2.750-61.977; p=0.001), nausea (OR 8.875; 95% CI 1.660-47.446; p=0.011), and lymphopenia (OR 3.575; 95% CI 1.355-9.430; p=0.010), but also had less hospitalizations (OR 0.355; 95% CI 0.138-0.916; p=0.032). The additional logistic regression analysis on patients with preexisting chronic conditions (n=108) showed that death as an outcome was significantly associated with pediatric severe acute respiratory syndrome (SARS) (OR 22.300; 95% CI 2.341-212.421; p=0.007) and multisystem inflammatory syndrome in children (MIS-C) (OR 11.261; 95% CI 1.189-106. 581; p=0.035). CONCLUSIONS: Half of the laboratory-confirmed COVID-19 cases occurred in adolescents. Individuals belonging to this age group had an acute systemic involvement of SARS-CoV-2 infection. Pediatric SARS and MIS-C were the most important factors associated with the mortality rate in pediatric chronic conditions with COVID-19.

- Immunothrombosis and COVID-19-a nested post-hoc analysis from a 3186 patient cohort in a Latin American public reference hospital(2023) LIMA, Clarice Antunes de; GONCALVES, Fabio Augusto Rodrigues; BESEN, Bruno Adler Maccagnan Pinheiro; PEREIRA, Antonio Jose Rodrigues; PERAZZIO, Sandro Felix; TRINDADE, Evelinda Marramon; FONSECA, Luiz Augusto Marcondes; SUMITA, Nairo Massakazu; PINTO, Vanusa Barbosa; DUARTE, Alberto Jose da Silva; MANIN, Carolina Broco; LICHTENSTEIN, ArnaldoObjective: COVID-19 is associated with an elevated risk of thromboembolism and excess mortality. Difficulties with best anticoagulation practices and their implementation motivated the current analysis of COVID-19 patients who developed Venous Thromboembolism (VTE). Method: This is a post-hoc analysis of a COVID-19 cohort, described in an economic study already published. The authors analyzed a subset of patients with confirmed VTE. We described the characteristics of the cohort, such as demographics, clinical status, and laboratory results. We tested differences amid two subgroups of patients, those with VTE or not, with the competitive risk Fine and Gray model. Results: Out of 3186 adult patients with COVID-19, 245 (7.7%) were diagnosed with VTE, 174 (5.4%) of them dur-ing admission to the hospital. Four (2.3% of these 174) did not receive prophylactic anticoagulation and 19 (11%) discontinued anticoagulation for at least 3 days, resulting in 170 analyzed. During the first week of hospitaliza-tion, the laboratory most altered results were C-reactive protein and D-dimer. Patients with VTE were more criti-cal, had a higher mortality rate, worse SOFA score, and, on average, 50% longer hospital stay. Conclusion: Proven VTE incidence in this severe COVID-19 cohort was 7.7%, despite 87% of them complying completely with VTE prophylaxis. The clinician must be aware of the diagnosis of VTE in COVID-19, even in patients receiving proper prophylaxis.
- Use and misuse of biomarkers and the role of D-dimer and C-reactive protein in the management of COVID-19: A post-hoc analysis of a prospective cohort study(2021) GONCALVES, Fabio Augusto Rodrigues; BESEN, Bruno Adler Maccagnan Pinheiro; LIMA, Clarice Antunes de; CORA, Aline Pivetta; PEREIRA, Antonio Jose Rodrigues; PERAZZIO, Sandro Felix; GOUVEA, Christiane Pereira; FONSECA, Luiz Augusto Marcondes; TRINDADE, Evelinda Marramon; SUMITA, Nairo Massakazu; DUARTE, Alberto Jose da Silva; LICHTENSTEIN, ArnaldoOBJECTIVE: Coronavirus disease 2019 (COVID-19) is associated with high mortality among hospitalized patients and incurs high costs. Severe acute respiratory syndrome coronavirus 2 infection can trigger both inflammatory and thrombotic processes, and these complications can lead to a poorer prognosis. This study aimed to evaluate the association and temporal trends of D-dimer and C-reactive protein (CRP) levels with the incidence of venous thromboembolism (VTE), hospital mortality, and costs among inpatients with COVID-19. METHODS: Data were extracted from electronic patient records and laboratory databases. Crude and adjusted associations for age, sex, number of comorbidities, Sequential Organ Failure Assessment score at admission, and D-dimer or CRP logistic regression models were used to evaluate associations. RESULTS: Between March and June 2020, COVID-19 was documented in 3,254 inpatients. The D-dimer level >= 4,000 ng/mL fibrinogen equivalent unit (FEU) mortality odds ratio (OR) was 4.48 (adjusted OR: 1.97). The CRP level >= 220 mg/dL OR for death was 7.73 (adjusted OR: 3.93). The D-dimer level >= 4,000 ng/mL FEU VTE OR was 3.96 (adjusted OR: 3.26). The CRP level >= 220 mg/dL OR for VTE was 2.71 (adjusted OR: 1.92). All these analyses were statistically significant (p <0.001). Stratified hospital costs demonstrated a dose-response pattern. Adjusted D-dimer and CRP levels were associated with higher mortality and doubled hospital costs. In the first week, elevated D-dimer levels predicted VTE occurrence and systemic inflammatory harm, while CRP was a hospital mortality predictor. CONCLUSION: D-dimer and CRP levels were associated with higher hospital mortality and a higher incidence of VTE. D-dimer was more strongly associated with VTE, although its discriminative ability was poor, while CRP was a stronger predictor of hospital mortality. Their use outside the usual indications should not be modified and should be discouraged.
- Persistent symptoms and decreased health-related quality of life after symptomatic pediatric COVID-19: A prospective study in a Latin American tertiary hospital(2021) FINK, Thais T.; MARQUES, Heloisa H. S.; GUALANO, Bruno; LINDOSO, Livia; BAIN, Vera; ASTLEY, Camilla; MARTINS, Fernanda; MATHEUS, Denise; MATSUO, Olivia M.; SUGUITA, Priscila; TRINDADE, Vitor; PAULA, Camila S. Y.; FARHAT, Sylvia C.

RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.
- Cost-Effective Trap qPCR Approach to Evaluate Telomerase Activity: an Important Tool for Aging, Cancer, and Chronic Disease Research(2021) PINTO, Thalyta Nery Carvalho; FERNANDES, Juliana Ruiz; ARRUDA, Lia Barbara; DUARTE, Alberto Jose da Silva; BENARD, GilOBJECTIVES: Telomeres are a terminal ""DNA cap"" that prevent chromosomal fusion and degradation. However, aging is inherent to life, and so is the loss of terminal sequences. Telomerase is a specialized reverse transcriptase encoded by self-splicing introns that counteract chromosome erosion. Telomerase activity is observed during early embryonic development, but after the blastocyst stage, the expression of telomerase reduces. The consequences of either insufficient or unrestrained telomerase activity underscore the importance of ongoing studies aimed at elucidating the regulation of telomerase activity in humans. In the present study, we aimed to standardize a simplified telomerase repeat-amplification protocol (TRAP) assay to detect telomerase activity in unstimulated and PHA-stimulated mononuclear cells. METHODS and RESULTS: Our optimized qPCR-based can efficiently evaluate telomerase activity. Quantification of protein and DNA between unstimulated and PHA-stimulated peripheral blood mononuclear cells revealed cellular activation and cell-cycle entry. The assay also showed that relative telomerase activity is significantly different between these two conditions, supporting the applicability of the assay. Furthermore, our findings corroborated that telomerase activity decreases with age. CONCLUSIONS: Telomeres and telomerase are implicated in aging and development of chronic diseases and cancer; however, difficulty in accessing commercial kits to investigate these aspects is a critical constraint in health surveillance studies. Our optimized assay was successfully used to differentiate telomerase activity between unstimulated and stimulated cells, clearly showing the reactivation of telomerase upon cell activation. This assay is affordable, reproducible, and can be executed in resource-limited settings.
