    Brandão, Carolina Felipe Soares; Bergamasco, Ellen Cristina; Vaccarezza, Gabriela Furst; Barba, Maria Luiza Ferreira de; Andrade, Enrico Ferreira Martins de; Cecilio-Fernandes, Dario

    Resumo em Inglês:

    SUMMARY INTRODUCTION: The challenge of facing COVID-19 falls under all health care structures, and without specific training to health care professionals they are probably the professionals with the highest level of exposure. Regardless of the level of health care, the training of professionals aims to optimize resources and attend patients while assuring quality and security. POINT OF VIEW: This report proposes simulation training for health care professionals to update professionals for attending patients during the pandemic. This training was built with five simulated stations, considering different stages of a patient with COVID-19. This report takes advantage of different simulation techniques, such as skills training, standardized patient, medium- and high-fidelity simulator, rapid cycle of deliberate practice, and in situ simulation. DISCUSSION: Medical procedures for COVID-19 patients offer additional risk for health care professionals, especially considering exposure to procedures that generate aerosols, such as compression, mask ventilation, and orotracheal intubation. Thus, finding educational strategies that allow training is essential to simulate the evolution of COVID-19 patients in a safe manner. CONCLUSION: Simulation has proven to be a useful and effective form of training around the world for training health teams on the front lines for patient care in COVID-19.
  • Possible role of exogenous melatonin in preventing more serious COVID-19 infection in patients with type 2 diabetes mellitus Point Of View

    Martorina, Wagner José; Tavares, Almir

    Resumo em Inglês:

    SUMMARY COVID-19 infection is more severe in patients with type 2 diabetes mellitus (DM2). The severity of this viral infection is associated with an intense inflammatory activity. DM2 is a disease that also determines a greater degree of systemic inflammation. This is due to hyperglycemia, the higher prevalence of sleep disorders and also the low levels of melatonin, a substance with anti-inflammatory actions, in these patients. In this article, we suggest that exogenous melatonin may have an important anti-inflammatory role in preventing severe forms of COVID -19 in patients with DM2.
  • Reflections on passive smoking and COVID-19 Point Of View

    Garcia, Leilinéia Pereira Ramos de Rezende; Abreu, Cibelly Correia Souza; Abe, Adriana Helena de Matos; Matos, Marcos André de

    Resumo em Inglês:

    Despite substantial evidence on the negative effect of active smoking to Covid-19, the impact of passive smoking in the course of disease remains largely unclear. Our aim was to reflect passive smoking as a risk factor in the current pandemic. Studies are needed to increase our knowledge on passive smoking and Covid-19 implications. The reflections current findings strongly support interventions and policies to curb the tobacco epidemic.
  • Bundle for pediatric COVID-19 sepsis Short Communication

    Fernández-Sarmiento, Jaime; de Carvalho, Werther Brunow

    Resumo em Inglês:

    SUMMARY COVID-19 infection can progress to severe respiratory infection and have high mortality rates. Several pathophysiological factors are observed in fatal cases, with mortality related to multiple organ failure, in addition to the evolution with high levels of serum ferritin, D-dimer, and C-reactive protein. These severe cases often meet the criteria for macrophage activation syndrome with changes in the host’s inflammatory response and an inadequate resolution phase. In the present study, the bundle for COVID-19 sepsis is proposed, including early recognition; protection, handwashing and isolation measures; oxygen therapy; early invasive mechanical ventilation; treatment aimed at modifying the clinical course. This strategy may be useful in the control of children with severe COVID-19 cases, as already demonstrated with the implementation of bundles in sepsis and other etiologies.

    de Mélo, Kathleen Cézar; de Souza Lôbo, Jéssica Luzia; da Silva Junior, Adeilton Gonçalves; do Carmo, Rodrigo Feliciano; de Souza, Carlos Dornels Freire

    Resumo em Inglês:

    SUMMARY INTRODUCTION: Coronavirus disease 2019 (COVID-19) is the disease caused by a novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In the ongoing obesity pandemic, its coexistence with COVID-19 becomes worrying and has a less favorable outcome. OBJECTIVE: This study aimed to describe the clinical and epidemiological profiles of confirmed cases of COVID-19 in individuals with obesity in the state of Alagoas. METHODS: The observational cross-sectional study involving 138 confirmed cases of COVID-19 who had obesity as a comorbidity reported at the time of notification of the disease. The data were collected from the COVID-19 database in the state of Alagoas, and the variables analyzed were sex, age (and age group), race/color, outcome, clinical manifestations, and associated comorbidities. The Kolmogorov–Smirnov, Mann-Whitney U, χ², or Fisher’s exact tests were performed as appropriate. The significance was set at 5 and 95% confidence intervals. RESULTS: There was a predominance of females (55.1%; n=76), aged <60 years (70.3%; n=97) and brown race/color (n=76; 55.1%). The most prevalent symptoms were cough (n=84; 60.9%), fever (n=78; 56.5%), headache (n=36; 26.1%), and adynamia (n=28; 20.3%). The median age was 49 years, with no difference between genders (p=0.340). The lethality rate was 17.4% (n=24), being higher in the male population (22.6% in males and 13.2% in females). Of the 24 deaths, 13 (54.2%) were recorded in the elderly people. In addition to obesity, 54.3% (n=75) had systemic arterial hypertension and 30.4% (n=42) had diabetes mellitus. There was no difference in the prevalence of comorbidity between genders. CONCLUSIONS: The profile studied demonstrates that obesity represents a challenge for coping with COVID-19.

    Ritti-Dias, Raphael Mendes; Cucato, Gabriel Grizzo; Oliveira, Max Duarte de; Braghieri, Heloisa Amaral; Carvalho, Juliana Ferreira de; Wolosker, Nelson; Correia, Marilia de Almeida; Kanegusuku, Hélcio

    Resumo em Inglês:

    SUMMARY OBJECTIVE: To describe physical activity habits and barriers for physical activity practice in patients with peripheral artery disease and claudication symptoms during Coronavirus 2019 (COVID-19) pandemic. METHODS: In this cross-sectional survey study, 127 patients with peripheral artery disease (59.8% men; 68±9 years old; and 81.9% had the peripheral artery disease diagnosis ≥5 years old) were included. The physical activity habits and barriers for physical activity practice were assessed through telephone interview using a questionnaire with questions related to: (a) COVID-19 personal care; (b) overall health; (c) physical activity habits; (d) for those who were inactive, the barriers for physical activity practice. RESULTS: Only 26.8% of patients reported practicing physical activity during the COVID-19 pandemic. Exercise characteristics more common among these patients include walking, performed at least 5 days a week, during 31–60 min at light intensity. In contrast, among physically inactive patients, pain, injury or disability (55%), the COVID-19 pandemic (50%), the need to rest due to leg pain (29%), and lack of energy (27%) were the most frequent barriers to physical activity practice. CONCLUSION: The physical activity level of patients with peripheral artery disease is impacted by the COVID-19 pandemic.
  • Comparison of neutrophil lymphocyte ratio, platelet lymphocyte ratio, and mean platelet volume and PCR test in COVID-19 patients Original Article

    Özsari, Süleyman; Özsari, Emine; Emin Demirkol, Muhammet

    Resumo em Inglês:

    SUMMARY OBJECTIVE: The polymerase chain reaction test, used in the diagnosis of COVID-19, can be positive with delay, and thorax tomography is used for the diagnosis of the disease. We aimed to compare the relation between thorax tomography findings, PCR test results, and neutrophil lymphocyte ratio; platelet lymphocyte ratio and mean platelet volume neutrophil lymphocyte ratio; platelet lymphocyte ratio and mean platelet volume in COVID-19 patients. METHODS: COVID-19 patients were divided into three groups, according to baseline laboratory and thorax tomography findings: Group A: thorax tomography finding positive – polymerase chain reaction test positive; Group B: thorax tomography finding negative – polymerase chain reaction test positive; and Group C: thorax tomography finding positive – polymerase chain reaction test negative. Neutrophil lymphocyte ratio, platelet lymphocyte ratio, and mean platelet volume values were compared between these three groups. RESULTS: Group C neutrophil lymphocyte ratio level and polymerase chain reaction level were statistically higher than that of group B (p<0.001 in both). Mean platelet volume was not statistically significant between groups (p>0.005 for all). A positive correlation was detected between neutrophil lymphocyte ratio and C-reactive protein (r=0.421, p<0.001). Similarly, positive correlation was found with polymerase chain reaction and C-reactive protein (r=0.243, p=0.001). CONCLUSIONS: The thorax tomography finding can be detected earlier in the disease before the polymerase chain reaction test. The sensitivity of the polymerase chain reaction test varies according to the tester, the way of performing it, and the quality of the test. Therefore, especially in patients with polymerase chain reaction negative and thorax tomography findings, neutrophil lymphocyte ratio and platelet lymphocyte ratio levels should be evaluated, and patients should be followed up upon suspicion of COVID-19 diagnosis.
  • Association of ABO blood group and age with COVID-19 positive test Original Article

    Nalbant, Ahmet; Aydın, Ayhan; Yaylacı, Selçuk; Kaya, Tezcan; Wermeulen, Charlotte Lynn; Cinemre, Hakan

    Resumo em Inglês:

    ABSTRACT OBJECTIVE: The aim of this study is to evaluate the relation between the coronavirus (SARS-CoV-2) disease (COVID-19) and blood groups and the Rh factor. METHOD: A total of 313 patients hospitalized in the Internal Medicine clinic, at the intensive care unit (ICU) were included in the study. The cases were divided into two groups: those who were COVID-19 positive and those negative, detected with real-time reverse transcription polymerase chain reaction testing. The demographic, clinical, ABO blood groups, and Rh factor data of the cases were obtained from the hospital records retrospectively. RESULTS: The mean age of COVID-19 positive (+) cases was 57.74±16 years and of COVID-19 negative (-) cases, 66.41±15 years. The difference was significant (p<0.001); there was no difference between the two groups in terms of sex (p=0.634). When age was categorically separated in COVID-19 (+) cases, χ2 was extremely significant. Among the ABO blood groups of COVID-19 (+) and (-) cases, χ2 was 4.975 (p=0.174). In the logistic regression, it was 4.1 (p=0.011) in the O blood group. COVID-19 positive test was determined as 13, 4, and 4 times higher in the 31–40, 41–50, and 51–60 age groups, respectively (p=0.001, p=0.010, p=0.003). CONCLUSION: The incidence of COVID-19 has increased in the younger population and in the O blood group. Our findings support that, in this population, the ABO blood groups can contribute to the early detection of COVID-19.

    Dheir, Hamad; Karacan, Alper; Sipahi, Savas; Yaylaci, Selcuk; Tocoglu, Aysel; Demirci, Taner; Cetin, Esma Seda; Guneysu, Fatih; Firat, Necattin; Varim, Ceyhun; Karabay, Oguz

    Resumo em Inglês:

    SUMMARY The purpose of this study was to investigate the relation between venous blood gas and chest computerized tomography findings and the clinical conditions of COVID-19 pneumonia. METHODS: A total of 309 patients admitted to the emergency department and subsequently confirmed COVID-19 cases was examined. Patients with pneumonia symptoms, chest computerized tomography scan, venous blood gas findings, and confirmed COVID-19 on reverse transcription-polymerase chain reaction (PCR) were consecutively enrolled. Multiple linear regression was used to predict computerized tomography and blood gas findings by clinical/laboratory data. RESULTS: The median age of patients was 51 (interquartile range 39–66), and 51.5% were male. The mortality rate at the end of follow-up was 18.8%. With respect to survival status of patients pCO2 and HCO3 levels and total computerized tomography score values were found to be higher in the surviving patients (p<0.001 and p=0.003, respectively), whereas pH and lactate levels were higher in patients who died (p=0.022 and p=0.001, respectively). With logistic regression analysis, total tomography score was found to be significantly effective on mortality (p<0.001). The diffuse and random involvement of the lungs had a significant effect on mortality (p<0.001, 95%CI 3.853–38.769, OR 12.222 and p=0.027; 95%CI 1.155–11.640, OR 3.667, respectively). With linear regression analysis, the effect of pH and lactate results were found to have a positive effect on total tomography score (p=0.003 and p<0.001, respectively), whereas pCO2 was found to have a negative effect (p=0.029). CONCLUSION: There was correlation between venous blood gas indices and radiologic scores in COVID-19 patients. Venous blood gas taken in emergency department can be a fast, applicable, minor-invasive, and complementary test in terms of diagnosing COVID-19 pneumonia and predicting the prognosis of disease.
  • COVID-19 pandemic information on Brazilian websites: credibility, coverage, and agreement with World Health Organization Original Article

    Sousa Filho, Luis Fernando; Santos, Marta Maria Barbosa; Silva Júnior, Walderi Monteiro da

    Resumo em Inglês:

    SUMMARY OBJECTIVE: To assess the credibility and the quality content of COVID-19 pandemic information on Brazilian websites. METHODS: We performed Google searches and screened the first 45 websites. The websites were categorized as academic, commercial, government, hospital, media, nongovernmental organizations, and professionals. The credibility was assessed by JAMA benchmark criteria and HONCODE. A checklist with WHO information about COVID-19 was developed to assess the quality content. For each website, the level of agreement with WHO information was categorized into “total,” “partial,” or “disagreement”. RESULTS: A total of 20 websites were analyzed. None of the websites had HONCODE certification. Six websites (30%) met none of the four JAMA criteria and only one website (5%) fulfilled all the four criteria. Only 11 out of 20 websites showed overall coverage >50% for the checklist. Overall, 70% (14/20) of the websites had at least 50% total agreement with WHO items. The government websites presented more disagreement with the WHO items than media websites in the overall quality content analysis. CONCLUSION: The COVID-19 information on Brazilian websites have a moderate-to-low credibility and quality, particularly on the government websites.

    Pestana, José Medina; Cristelli, Marina Pontello; Viana, Laila Almeida; Fernandes, Ruan de Andrade; Nakamura, Monica Rika; Foresto, Renato Demarchi; Martins, Suelen Bianca Stopa; Santos, Daniel Wagner de Castro Lima; Aguiar, Wilson Ferreira; Vaz, Maria Lucia dos Santos

    Resumo em Inglês:

    SUMMARY OBJECTIVE: This study aims to describe the result of the strategies adopted to maintain the transplant program amid the COVID-19 pandemic. METHODS: Since March 2020, several measures have been adopted sequentially, including the compulsory use of personal protective equipment and the real-time polymerase chain reaction testing of collaborators, symptomatic patients, potential deceased donors, candidates for recipients, and in-hospital readmissions, regardless of symptoms. The living-donor transplantation was restricted to exceptional cases. RESULTS: Among 1013 health professionals, 201 cases of COVID-19 were confirmed between March and August 2020, with no severe cases reported. In this period, we observed a 19% institutional increase in the number of transplants from deceased donors compared with that observed in the same period in 2019. There was no donor-derived severe acute respiratory syndrome virus (SARS-CoV-2) infection. Four COVID-19-positive patients underwent transplantation; after 28 days, all were alive and with functioning allograft. Among the 11,875 already transplanted patients being followed up, there were 546 individuals with confirmed diagnosis, 372 who required hospitalization, and 167 on mechanical ventilation, resulting in a 27% mortality rate. CONCLUSIONS: These data confirm that the adoption of sequential and coordinated measures amid the pandemic was able to successfully maintain the transplant program and ensure the safety of health professionals and transplanted patients who were already in follow-up.
  • Roles of certain biochemical and hematological parameters in predicting mortality and ICU admission in COVID-19 patients Original Article

    Bilgir, Ferda; Çalık, Şebnem; Demir, İsmail; Bilgir, Oktay

    Resumo em Inglês:

    SUMMARY OBJECTIVE: In this study, we aimed to retrospectively analyze the roles of certain hematological and biochemical parameters in predicting mortality and intensive care unit admission in patients diagnosed with coronavirus disease 2019 (COVID-19). METHODS: We analyzed the complete blood count and biochemical parameters of 186 COVID-19 patients by using the polymerase chain reaction test. Whether these parameters can be used to predict intensive care unit admission and mortality in the COVID-19 patients was investigated. RESULTS: The complete blood count and biochemical parameters of COVID-19 patients and in those admitted to intensive care unit were compared. The red cell distribution width, ferritin, lactate dehydrogenase, D-dimer, C-reactive protein, prothrombin time, and creatinine levels were found to be the most significant parameters. We found that these parameters are significant for predicting not only intensive care unit admission, but also the mortality of the patients admitted to the intensive care unit. CONCLUSIONS: We determined that the most effective parameters to predict intensive care unit admission and mortality in COVID-19 patients are ferritin, lactate dehydrogenase, D-dimer, C-reactive protein, red cell distribution width, creatinine, and intensive care unit. Close monitoring of these parameters and early intervention in alterations are of vital importance.

    Ozdin, Mehmet; Cokluk, Erdem; Yaylaci, Selçuk; Koroglu, Mehmet; Genc, Ahmed Cihad; Cekic, Deniz; Aydemir, Yusuf; Karacan, Alper; Erdem, Ali Fuat; Karabay, Oguz

    Resumo em Inglês:

    SUMMARY OBJECTIVE: This study aims to investigate and compare the coagulation parameters of coronavirus disease 2019 (COVID-19) patients with mortal and nonmortal conditions. METHODS: In this study, 511 patients diagnosed with COVID-19 were included. Information about 31 deceased and 480 recovered COVID-19 patients was obtained from the hospital information management system and analyzed retrospectively. Whether there was a correlation between coagulation parameters between the mortal and nonmortal patients was analyzed. Descriptive analyses on general characteristics of the study population were performed. Visual (probability plots and histograms) and analytical methods (Kolmogorov–Smirnov and Shapiro–Wilk test) were used to test the normal distribution. Analyses were performed using the SPSS statistical software package. RESULTS: Out of 511 patients, 219 (42.9%) were females and 292 (57.1%) were males. There was no statistically significant difference between males and females in terms of mortality (p=0.521). In total, the median age was 67 (22). The median age was 74 (13) in the nonsurvivor group and 67 (22) in the survivor group, and the difference was statistically significant (p=0.007). The D-dimer, prothrombin time, international normalized ratio, neutrophil, and lymphocyte median age values with p-values, in the recovered and deceased patient groups were: 1070 (2129), 1990 (7513) μg FEU/L, p=0.005; 12.6 (2.10), 13.3 (2.1), p=0.014; 1.17 (0.21), 1.22 (0.19), p=0.028; 5.51 (6.15), 8.54 (7.05), p=0.001; and 0.99 (0.96), 0.64 (0.84), p=0.037, respectively, with statistically significant differences. CONCLUSIONS: As a result of this study, D-dimer, prothrombin time, and international normalized ratio increase were found to be associated with mortality. These parameters need to be closely monitored during the patient follow-up.
  • Evaluation of cardiac parameters between survivors and nonsurvivors of COVID-19 patients Original Article

    Ozdin, Mehmet; Yazar, Hayrullah; Yaylaci, Selcuk; Koroglu, Mehmet; Genc, Ahmed Cihad; Kocayigit, İbrahim; Genc, Ahmed Bilal; Yıldırım, İlhan; Kocayigit, Havva; Karabay, Oguz

    Resumo em Inglês:

    SUMMARY OBJECTIVE: The present study compares the cardiac parameters of the survivor and nonsurvivor patients with COVID-19 infection. METHODS: This study was conducted in 379 patients diagnosed with COVID-19 disease. Information of 21 nonsurvivor and 358 survivor patients with COVID-19 was obtained from the hospital information management system and analyzed retrospectively. Relationship between cardiac parameters in patients categorized into the mortal and immortal groups was investigated. RESULTS: Of the total 379 patients involved in this study, 155 (40.9%) were females and 224 (59.1%) were males. No statistically significant difference in mortality was found between females and males (p=0.249). The total median age was 70, the median age in the nonsurvivor group was 74 (35–89), and it was 69.5 (18–96) in the survivor group (p=0.249). The median values of high-sensitivity troponin (hs-Tn), creatine kinase MB form, and especially myoglobin in the survivor and nonsurvivor groups were 25/64.9 (p=0.028), 18/23 (p=0.02), and 105.5/322.4 (p<0.001), and the difference was statistically significant. Comparing mortality, while there was 1 (0.7%) nonsurvivor out of 134 patients in the service unit, there were 20 (8.2%) nonsurvivors out of 245 patients in the intensive care unit. This difference was statistically significant (p=0.003). The cutoff value of myoglobin, which may pose a risk of mortality, was found to be 191.4 µg/L, while it was 45.7 ng/l for hs-Tn and 60.1 U/L for creatine kinase MB. CONCLUSIONS: Advanced age and increased levels of high-sensitivity troponin, creatine kinase MB, and myoglobin were found to be associated with mortality.

    Fagundes, Thales Pardini; Albuquerque, Ronniel Morais; Miranda, Diego Lopes Paim; Landeiro, Luciana Castro Garcia; Ayres, Gabriel Souza Fontes; Correia, Caenna Corrêa e; Nogueira-Rodrigues, Angélica

    Resumo em Inglês:

    SUMMARY OBJECTIVE: This article aims to alert health professionals for cancer screening in the face of the possibility of new waves of disease. METHODS: A narrative review was conducted through a search in MEDLINE, Lilacs, Chinese Biomedical Literature Database, and international medical societies publications. RESULTS: Breast cancer: in high-risk patients (confirmed familial cancer syndrome or with high-risk tools scores), clinicians should act according to usual recommendations; in average-risk individuals, consider screening with mammography with a longer time span (maximum of two years). Cervical cancer: women turning 25 years old who have already been immunized and with no previous Pap test can have the test postponed during the pandemic; if there is no previous dose of Human Papillomavirus vaccination, initiation of screening should be recommended following a more rigid approach for COVID prevention; in women over 30 years of age who have never participated in cervical screening, the first screening exam is also essential. Colorectal cancer: if the individual is at elevated risk for familial cancer, the screening with colonoscopy according to usual recommendations should be supported; if at average risk consider screening with Fecal Occult Blood Test. Prostate cancer: there is a trend to postpone routine prostate cancer screening until the pandemic subsides. CONCLUSIONS: The decision to keep cancer screening must be discussed and individualized, considering the possibility of new waves of COVID-19.
  • The role of serum inflammatory markers, albumin, and hemoglobin in predicting the diagnosis in patients admitted to the emergency department with a pre-diagnosis of COVID-19 Original Article

    Akman, Canan; Bakırdöğen, Serkan

    Resumo em Inglês:

    SUMMARY OBJECTIVE: Serum inflammatory markers and albumin levels provide an assumption for the severity of COVID-19 infection. Our objective was to investigate the determinant role of serum inflammatory markers, albumin, and hemoglobin (Hb) in predicting the diagnosis in patients with a pre-diagnosis of COVID-19. METHODS: Demographic findings, complete blood count and serum biochemical values of the patients analyzed. RESULTS: Of the patients included in the study, 48 were COVID (+) and 253 were COVID (-). Statistically significant difference was found in terms of hemoglobin, mean platelet volume, and monocyte/eosinophil ratio. CONCLUSIONS: The levels of serum albumin, hemoglobin, monocyte/eosinophil ratio, and mean platelet volume can be predictive factors for diagnosis in patients with COVID-19.
  • Clinician’s perspective regarding medication adherence in patients with obstructive lung diseases and the impact of COVID-19 Original Article

    Yıldız, Murat; Aksu, Funda; Yıldız, Nurdan; Aksu, Kurtuluş

    Resumo em Inglês:

    SUMMARY OBJECTIVE: Failure to achieve high levels of medication adherence in obstructive lung diseases is a major cause of uncontrolled disease. The purpose of this study is to reveal clinicians’ opinions on the level of patient adherence and the change in adherence during the COVID-19 pandemic. METHODS: A questionnaire containing multiple-choice questions about treatment adherence in patients with obstructive lung diseases was voluntarily applied to doctors working in a tertiary hospital for chest diseases. RESULTS: Eighty-one doctors (mean age, 37.2 years [standard deviation, 9.7 years]; 57 (70.4%) women) answered the questionnaires. Almost all clinicians participating in the study reported that they always or frequently asked patients if they adhered to treatment. Most clinicians think that in 20–50% of patients with asthma and less than 20% of patients with chronic obstructive pulmonary disease, a decrease in medication adherence appears in the first year of treatment. Most clinicians think the main reason for patients with obstructive lung diseases not adhering is patients’ reluctance to be treated regularly. Regarding the impact of the COVID-19 pandemic on patients’ drug adherence, 43.2% of clinicians observed that adherence increased after the start of the pandemic. CONCLUSIONS: Adherence to medication is not at the desired levels in patients with obstructive lung diseases. However, when faced with a serious health threat, such as the COVID-19 pandemic, patients realize the severity of their illness and begin using their treatments more regularly.
  • Physical Exercise and Immune System: Perspectives on the COVID-19 pandemic Review Article

    Improta-Caria, Alex Cleber; Soci, Úrsula Paula Renó; Pinho, Cristiano Silva; Aras Júnior, Roque; De Sousa, Ricardo Augusto Leoni; Bessa, Theolis Costa Barbosa

    Resumo em Inglês:

    Physical exercise training (PET) has been considered an excellent non-pharmacological strategy to prevent and treat several diseases. There are various benefits offered by PET, especially on the immune system, promoting changes in the morphology and function of cells, inducing changes in the expression pattern of pro and anti-inflammatory cytokines. However, these changes depend on the type, volume and intensity of PET and whether it is being evaluated acutely or chronically. In this context, PET can be a tool to improve the immune system and fight various infections. However, the current COVID-19 pandemic, caused by SARS-CoV-2, which produces cytokine storm, inducing inflammation in several organs, with high infection rates in both sedentary and physically active individuals, the role of PET on immune cells has not yet been elucidated. Thus, this review focused on the role of PET on immune system cells and the possible effects of PET-induced adaptive responses on SARS-CoV-2 infection and COVID-19.
  • Ototoxic effects of hydroxychloroquine Review Article

    Gonçalves, Laura Faustino; Patatt, Fernanda Soares Aurélio; de Paiva, Karina Mary; Haas, Patrícia

    Resumo em Inglês:

    SUMMARY OBJECTIVE To present scientific evidence based on a systematic review of the literature (PRISMA), aiming to systematize evidence of the ototoxic effects of hydroxychloroquine (HCQ). METHODS The studies were selected using a combination based on the Medical Subject Headings (MeSH). The databases searched were MEDLINE (PubMed), LILACS, SciELO, and BIREME, encompassing articles from January 2010 to May 2020, with no restrictions of language and place of publication. RESULTS A total of 148 articles with the potential to be included were retrieved. Of these, two answered the research question, which consisted of seeking evidence of the ototoxic effects of hydroxychloroquine. These studies scored 11 in their quality assessment with the modified protocol by Pithon et al.13. CONCLUSIONS The studies reported possible ototoxicity of HCQ. Audiovestibular changes, such as hearing loss, peripheral vestibular syndrome, and tinnitus were evidenced in patients submitted to HCQ. The improvement in the audiological examinations and the regression in the vestibular syndrome after stopping the treatment with HCQ are strong arguments in favor of the ototoxicity caused by this medication. However, there are still divergences about the relationship between ototoxic effects and the use of HCQ.

    Nogueira-de-Almeida, Carlos Alberto; Ciampo, Luiz Antonio Del; Ferraz, Ivan Savioli; Ciampo, Ieda Regina Lopes Del; Contini, Andrea Aparecida; Ued, Fábio da Veiga

    Resumo em Inglês:

    SUMMARY OBJECTIVE: To identify epidemiological and clinical characteristics of multisystemic inflammatory syndrome associated with coronavirus infection as one of the severe forms of COVID-19 involvement in children and adolescents. METHODS: review was based on articles published in 2020 in the PubMed, Medline, Scopus, SciELO and Cochrane databases. SUMMARY: Multisystemic inflammatory syndrome is a serious clinical disorder that affects children and adolescents and is associated with the detection of previous exposure to SARS-CoV-2. It is characterized by the installation of a shock picture, with a significant increase in inflammatory markers such as presentations of Kawasaki Disease or shock syndrome related to Kawasaki Disease, or even toxic shock syndrome, with the clinical picture being characterized by fever of difficult control, rash, conjunctivitis, peripheral edema, generalized pain in the extremities and gastrointestinal symptoms. CONCLUSIONS: Although the vast majority of children with COVID-19 have mild symptoms, it is necessary to consider that some have a hyperinflammatory response. It is essential that health professionals receive information that can assist in the recognition of this clinical condition, differentiating it from other diagnoses, so that early and appropriate treatment is instituted.

    SUMMARY Severe Acute Respiratory Syndrome Coronavirus 2 is part of the Cononaviridae family and is the causative agent of the 2019 (Covid-19) Coronavirus pandemic declared by the World Health Organization in March, 2020. This virus has a high rate of transmission, affecting several individuals, and has caused thousands of deaths. The clinical manifestations of Severe Acute Respiratory Syndrome Coronavirus 2 infection are not restricted only to the respiratory tract, and there is an express involvement of the cardiovascular system with a higher risk of death in this group. In such patients there is an overactivation of renin-angiotensin-aldosterone system, which promotes an increase in the expression of angiotensin-converting enzyme – 2 that acts as a receptor for the SPIKE protein expressed by the virus and enables the interaction between the host cell and Severe Acute Respiratory Syndrome Coronavirus 2. This process of infection causes a hyperinflammatory state that increases the inflammatory markers of cardiac injury. Hence, an adequate understanding and clinical guidance regarding the monitoring, and controlling the damage in these patients is essential to avoid worsening of their clinical condition and to prevent death.

    SUMMARY BACKGROUND: Although much has been studied about the SARS-Cov-2 virus, its effects, and the effectiveness of possible treatments, little is known about its interaction with other infectious diseases. OBJECTIVE: The aim is to study its clinical features and morbidity, and mortality outcomes of COVID-19 patients with HIV/AIDS coinfection. DATA SOURCES: MEDLINE, Web of Science, Embase, CINAHL, LILACS, Scopus, ClinicalTrials.gov, and Cochrane. STUDY ELIGIBILITY CRITERIA: Atudies in any language, published after 2019, were describing COVID-19 patients with HIV/AIDS. STUDY APPRAISAL: JBI Levels of Evidence, Joanna Briggs Institute. SYNTHESIS METHODS: As shown in the PRISMA flow diagram, two authors separately screened the search results from the obtained titles and abstracts. RESULTS: Chest CT was observed in patients with pneumonia by SARS-CoV-2 with findings of multiple ground-glass opacities (GGO) in the lungs, there is a need for supplemental oxygenation. One patient developed encephalopathy and complicated tonic-clonic seizures; four patients were transplanted (two, liver; two, kidneys), one patient developed severe SARS-CoV-2 pneumonia and 30 patients died (mortality rate, 11%). CONCLUSION: HIV did not show any relevance directly with the occurrence of COVID-19. Some studies suggest that HIV-1 infection through induction levels of IFN-I, may to some extent, stop the apparent SARS-CoV-2 infection, thus leading to undetectable RNA. Moreover, some authors suggest retroviral therapy routinely used to control HIV infection could be used to prevent COVID-19 infection.
  • Diabetes in the COVID-19 pandemic era Review Article

    Resumo em Inglês:

    SUMMARY OBJECTIVE: To analyze the association between patients with diabetes mellitus and the increased severity and its complications that arise with a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. METHODS: This is a complementary review of literature in which 14 articles published in 2020 were selected. These reviewed articles were written in both Portuguese and English available in the SciELO and PubMed databases. This review also involved searching on websites of international and national organizations in order to gather information published by these bodies about diabetic population and coronavirus disease (COVID-19)-infected individuals. DISCUSSION: The presence of comorbidities in SARS-CoV-2-infected individuals causes an increase in the expression level of angiotensin-converting enzyme 2, facilitating the entry of the virus into the cell. Diabetes causes metabolic and vascular changes, thus weakening the immune system through the inhibition of the innate immune system and the secretion of various inflammatory cytokines. This hyperinflammation can lead to multiple organ failure. The interaction between this comorbidity and COVID-19 can worsen pre-existing diabetes or predispose the onset of diabetes in non-diabetic individuals. CONCLUSIONS: Diabetes mellitus is related to the increased severity and complications of COVID-19. The association between diabetes and COVID-19 creates a devastating double pandemic, as it worsens the prognosis of COVID-19.

    SUMMARY The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) induces coronavirus-19 disease (COVID-19), has affected many people in Brazil and worldwide. This disease predominantly affects the organs of the respiratory system, but it also damages the brain, liver, kidneys and especially the heart. In the heart, scientific evidence shows that this virus can damage the coronary arteries, generating microvascular dysfunction, favoring acute myocardial infarction. Furthermore, with the increased expression of pro-inflammatory cytokines, it can lead to myocarditis and cardiac fibrosis, inducing changes in the electrical conduction system of the heart, generating cardiac arrhythmias. All these factors mentioned are protagonists in promoting the increase in the mortality outcome. This outcome may be even higher if the individuals are elderly, or if they have other diseases such as type 2 diabetes mellitus or hypertension, because they may already have cardiomyopathy. In this context, this review focused on the impact that COVID-19 can have on the heart and cardiovascular system and the association of this impact with aging, type 2 diabetes mellitus, cardiac arrhythmias and arterial hypertension
