BACKGROUND: The pandemic of the new coronavirus has culminated in a scientific race to seek knowledge about this virus and its treatments, vaccines and preventive strategies, in order to reduce its impact on healthcare and economics worldwide. Hence, it is important to recognize the efforts of researchers who are at the forefront of investigations relating to the new coronavirus. OBJECTIVE: The present study was carried out with the aim of analyzing the world scientific production relating to COVID-19. DESIGN AND SETTING: Exploratory and descriptive bibliometric study conducted in the city of Teresina (PI), Brazil. METHOD: ISI Web of Knowledge/Web of Science (WOS) was chosen as the database. Data-gathering was carried out in May 2020. The data analysis was performed using the HistCiteTM software, version 9.8.24, and the VOSviewer bibliometric analysis software, version 1.6.8. RESULTS: 2,625 published papers that included descriptors within the scope of this investigation were identified. These articles were published in 859 different journals that are indexed in WOS, by 9,791 authors who were linked to 3,365 research institutions, located in 105 countries. CONCLUSION: Ascertaining scientific production through a bibliometric analysis is important in order to guide researchers on what has already been produced and what is being researched, so as to be able to address gaps in knowledge through future research.

This bibliometric analysis aims to analyze the global scientific production of COVID-19 and vaccines. First, a search for scientific articles was performed using the advanced query in the Web of Science™ database, more precisely in its core collection, on 18 February 2023. Data from 7754 articles were analyzed using the Bibliometrix R package and the Biblioshiny application. The evaluated articles were published mainly in 2022 (60%). The scientific journals that published the most about COVID-19 and vaccines were “Vaccines”, “Vaccine” and “Human Vaccines & Immunotherapeutics”. The University of Oxford was the most productive institution, with the authors of the articles mainly originating from the United States, China and the United Kingdom. The United States, despite having carried out the most significant number of collaborations, published mainly with local researchers. The 15 most cited articles and the KeyWords Plus™ evidenced the focus of the published articles on the safety and efficacy of vaccines against COVID-19, as well as on the evaluation of vaccine acceptance, more specifically on vaccine hesitancy. Research funding came primarily from US government agencies.

The aim of this study was to review the symptomatic manifestations of COVID-19 in children in the scientific literature. An integrative review of studies published between December 2019 and September 5, 2021, from the Medical Literature Analysis and Retrieval System Online, Web of Science, Scopus, Literatura Latino-Americana em Ciência de Saúde, and Base de Dados de Enfermagem databases, was carried out to answer the following research question: What symptomatic manifestations does COVID-19 cause in children?”. Twenty articles were included. The main symptoms described were fever, cough, diarrhea, vomiting, sore throat, dyspnea, headache, abdominal pain, malaise, and weakness or tiredness. The findings of this review can contribute to the diagnosis and clinical decision-making of the health team by providing information that facilitates the identification of COVID-19 in the target population, favoring early identification, better care, and consequently a better prognosis.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) infection is a worldwide concern given its presence even in non-hospitalized healthy individuals, such as university students. OBJECTIVE: To identify in the literature the prevalence of colonization by MRSA among healthcare students. DESIGN AND SETTING: Integrative review of the literature conducted in Universidade Federal do Piaui. METHOD: A search for primary studies was performed in the following databases: Medical Literature Analysis and Retrieval System on-line; Cumulative Index to Nursing and Allied Health Literature; Web of Science; Scopus; and LILACS. RESULTS: This review included 27 studies that demonstrated MRSA infection prevalence ranging from 0.0 to 15.3% among students. CONCLUSION: The prevalence of colonization of MRSA among healthcare students is high, and the nasal cavity was cited as an important reservoir location for these microorganisms.

A bibliometric analysis covering only the production of original studies or considering world production until 2022 has yet to be conducted. The creation and advancement of vaccines have also influenced research priorities, demonstrating the need for a new approach to this subject.

Assessing the quality of life (QoL) of older adults with intestinal stomas is crucial to understanding the impact of body image and lifestyle changes in this often-underrepresented population. This study aims to evaluate the QoL of older adults with intestinal stomas and analyze the influence of sociodemographic and clinical factors on different QoL domains. This cross-sectional study analyzed the QoL of 47 older adults with intestinal stomas, using the City of Hope Quality of Life—Ostomy Questionnaire (COHQOL-OQ). Data were collected from the outpatient Orthotics and Prosthetics Program and analyzed using R software (version 4.3.1). The majority of participants were male (59.6%), with a mean age of 68.8 ± 5.6 years. Cancer was the leading cause of stoma creation (70.2%), with 83.0% having colostomies and 57.4% permanent stomas. The overall QoL score was 6.71 ± 1.64, with the lowest scores in the physical well-being domain (6.21 ± 2.31) and the highest in the spiritual well-being domain (7.91 ± 1.73). Significant associations were found between QoL and type of ostomy (p = 0.008), self-managed pouch changes (p = 0.050), and physical activity (p = 0.034). The study highlights the importance of autonomy and targeted interventions, including physical activity programs and psychoeducational support, to enhance QoL in this population. The findings provide valuable insights for healthcare professionals and policymakers, contributing to the development of evidence-based interventions for older adults with stomas.
