ABSTRACT
ABSTRACT Background: The school community was heavily impacted by the Covid-19 pandemic, especially with the long time of school closures. This study aimed to analyze the seroprevalence of SARS-CoV-2 antibodies and possible factors associated with seropositivity for COVID-19 in teachers and other school staff, and to estimate the fraction of asymptomatic individuals by sex and age group. Methods: We conducted a serological survey of SARS-CoV-2 infections. An analytical cross-sectional study was conducted in Fortaleza, Brazil. Teachers and other staff members from pre-schools to universities of higher education to were investigated. Results: A total of 1,901 professionals participated in the study, of which 1,021 were staff and 880 were teachers. The seroprevalence of SARS-CoV-2 was 8.0% (152/1901). In the seropositive group, 48.3% were asymptomatic. There was a predominance of women (68.4%); and, 47.1% of the participants were between 31 and 45 years old. There was an increase in prevalence with increasing age. An inverse relationship was found for education level: more professionals with less education tested positive for COVID-19. The presence of an infected person living in the same household was significantly associated with positive results for COVID-19 among the professionals. Conclusions: This is the first study to report the seroprevalence of IgG against SARS-CoV-2 in Brazilian educational staff after the first wave of the disease. In this study, the seroprevalence was much lower than that in the general population. During school reopening, a small fraction of school workers showed serologically detectable signs of SARS-CoV-2 exposure.
ABSTRACT
Introduction: Sexually Transmitted Infections (STIs) are caused by viruses, fungi, bacteria, or other microorganisms, thus being a serious public health issue. Trichomonas vaginalis is the disease causative agent of trichomoniasis, a worldwide protozoan. The prevalence of trichomoniasis depends on some factors, including age, sexual activity, number of sexual partners, hygiene habits, among others. Objective: To evaluate the prevalence of Trichomonas vaginalis in gynecological cytology in a private laboratory in the city of Fortaleza, state of Ceará, Brazil. Methods: This is a retrospective, quantitative, and descriptive study carried out in a private laboratory in Fortaleza, state of Ceará. Data for the research, such as age, marital status, and symptoms, were collected from the patients' medical records as well as the prevalence of cases in liquid-based cytology (LBC) and conventional cytology (CC). Results: In 2019, 83 women were positive for trichomoniasis. The most prevalent age group was between 36 and 51 years old (41%), with an average of 39.9 years old. Regarding symptoms, 14 (16.8%) were asymptomatic and 41 (49.3%) had some symptom. Conclusion: The data obtained in this study describe the profile of women affected by Trichomonas vaginalis.
As infecções sexualmente transmissíveis são causadas por vírus, fungos, bactérias ou outros microrganismos, sendo assim um grave problema de saúde pública. O Trichomonas vaginalis, um protozoário presente em todo o mundo, é o agente etiológico causador da tricomoníase. A prevalência dessa doença depende de alguns fatores, incluindo idade, atividade sexual, números de parceiros sexuais, hábitos de higiene, entre outros. Objetivo: Avaliar a prevalência de Trichomonas vaginalis, em citologia ginecológica em um laboratório privado em Fortaleza, Ceará, Brasil. Métodos: Trata-se de estudo retrospectivo, quantitativo e descritivo realizado em laboratório privado em Fortaleza. Os dados para a pesquisa, como idade, estado civil, sintomas, foram retirados de prontuários das pacientes, assim como a prevalência de casos em citologia em meio líquido e CO. Resultados: No ano de 2019, 83 mulheres apresentaram positividade para tricomoníase. A faixa etária mais prevalente foi a de 36 a 51 anos (41%), ficando com a média de 39,9 anos. Em relação aos sintomas, 14 (16,8%), apresentaram-se assintomáticas e 41 (49,3%) apresentaram algum sintoma. Conclusão: Os dados obtidos neste estudo descrevem o perfil das mulheres acometidas pelo Trichomonas vaginalis.

A infecção respiratória aguda (IRA) é uma síndrome clínica, em que cerca de 80% dasmortes são atribuídas à pneumonia, uma doença grave que atinge o trato respiratórioinferior. O agente etiológico comumente isolado na pneumonia adquirida nacomunidade (PAC) é o Streptococcus pneumoniae (S. pneumoniae). As doençaspneumocócicas começam com a colonização do S. pneumoniae na nasofaringe, podendoprogredir para doença invasiva. Nas últimas décadas, o aumento do número de cepas deS. pneumoniae resistentes a antibióticos β-lactâmicos e a macrolídeos tem dificultado otratamento das infecções pneumocócicas. Os objetivos desse estudo foram determinar àprevalência de portadores de S. pneumoniae em crianças com PAC, o perfil desensibilidade a antimicrobianos e distribuição dos sorotipos, em Fortaleza, Brasil. Ascepas de S. pneumoniae foram isoladas de aspirados de nasofaringe de crianças comPAC atendidas no Hospital Infantil Albert Sabin (HIAS). Para a determinação dasConcentrações Inibitórias Mínimas (CIM) foi utilizado o método de E-test para osseguintes antimicrobianos: penicilina, ceftriaxona, sulfametoxazol/trimetoprim,amoxicilina, clindamicina e eritromicina. A genotipagem das cepas de S. pneumoniaefoi realizada pela técnica de multiplex PCR. De 527 amostras de crianças com PAC,foram isolados S. pneumoniae em 30,17%...
Acute respiratory infection is a clinical syndrome in which about 80% of deathsattributed to pneumonia, which is a serious disease that affects the lower respiratorytract. The etiologic agent commonly isolated in community-acquired pneumonia isStreptococcus pneumoniae (S. pneumoniae). Pneumococcal disease begins withcolonization of S. pneumoniae in the nasopharynx, which may progress to invasivedisease markedly. In recent decades, the increasing number of strains of S. pneumoniaeresistant to -lactam antibiotics and macrolides has hampered the treatment ofpneumococcal infections. The objectives of this study were to determine: (1) theprevalence of carriers of S. pneumoniae in children with community-acquiredpneumonia; (2) the profile of the sensitivity of the causative agent and the antimicrobial;(3) the distribution of serotypes existing in Fortaleza. The strains of S. pneumoniae wereisolated from nasopharyngeal aspirates from children with community-acquiredpneumonia treated at Children's Hospital Albert Sabin public. Penicillin, ceftriaxone,sulfamethoxazole / trimethoprim, amoxicillin, clindamycin and erythromycin: Todetermine the minimum inhibitory concentration method the E-test for the followingantimicrobials were used. Genotyping of the strains of S. pneumoniae was performed bymultiplex PCR. A total of 527 samples with carriers of community-acquired pneumoniain children were isolated 30.17% of strains of S...
