Introduction: The new corona virus (2019-nCoV OR HCOV-19 or CoV2), has emerged in China as the main cause of viral pneumonia (COVID-19, Coronavirus Disease-19). Objective: To provide evidence-based Physiotherapy and functionality in patients with adult and pediatric COVID-19. Methods: This is an integrative literature review using the MedLine / PubMed databases, library of Latin American and Caribbean Literature in Health Sciences (LILACS) and Physiotherapy Evidence Database (PEDRo). Results: Part of the patients with covid 19 show signs of respiratory deficiency with hypoxemia, with low severity in children. Impaired functionality is also expected. Conclusion: COVID-19 causes low pulmonary compliance and important changes in lung function with hypoxemia and cardiovascular repercussions. These changes lead to the need for Physiotherapy and the management of oxygen therapy and ventilatory support (invasive and non-invasive) for these patients.
Introduction: Although manual hyperinflation (MHI) is a physical therapy technique commonly used in intensive care and emergency units, there is little consensus about its use. Objective: To investigate the knowledge of physical therapists working in intensive care and emergency units about manual hyperinflation. Methods: Data were collected through self-administered questionnaires on manual hyperinflation. Data collection took place between September 2014 and January 2015, in Itabuna and Ilhéus, Bahia, Brazil. Results: The study sample was composed of 32 physical therapists who had between 4 months and 10 years working experience. All respondents affirmed that they used the technique in their professional practice. However, only 34.4% reported it to be a routine practice. 90.6% stated that the most common patient position during manual hyperinflation is “supine”. Participants were almost unanimous (93.8%) in citing secretion removal and cough stimulation as perceived benefits of MHI. High peak airway pressure was identified as being a precaution to treatment with MHI by 84.4% of participants, whilst 100% of the sample agreed that an undrained pneumothorax was a contraindication to MHI. Conclusion: The most common answers to the questionnaire were: supine position during MHI; secretion removal and cough stimulation as perceived benefits; high peak airway pressure as a precaution; and an undrained pneumothorax as a contraindication.
Background: Exposure to viral antigens that share amino acid (AA) sequence similar with self-antigens might trigger autoimmune diseases in genetically predisposed individuals, and the molecular mimicry theory suggests that epitope mimicry between the virus and human proteins can activate autoimmune diseases like type 1 diabetes (T1DM). Objective: The purpose of this study is to explore the possible similarity between the AA sequences of human glutamic acid decarboxylase - 65 kDa isoform (GAD65) human insulin, and proteins of H1N1 influenza (strain (A/California/7/2009(H1N1)), using databanks of proteins and immunogenic peptides to explain the development of T1DM. Methods: AA sequences of the A/California/7/2009(H1N1) strain, GAD65 and human insulin, available in the NCBI (National Center for Biotechnology Information) database were compared using the Basic Local Alignment Search Tool (BLAST) software. Results: Similarities were found among the A/California/7/2009(H1N1) strain, GAD and the human insulin. The similarities between Influenza A virus (A/California/7/2009(H1N1)) and the GAD65 ranged from 15.0 % to 56.0%, with statistical significance (P 0.006 and P 0.017). The similarities between the Influenza A virus (A/California/7/2009(H1N1)) and insulin ranged from 38.0 % to 45.0%, but without statistical significance. Conclusion: Bioinformatics data suggest a possible pathogenic link between A/California/7/2009(H1N1) and T1DM. Through molecular mimicry is has been observed that sequences similarity between viral Polyprotein and self-proteins could induce a crossover immune response to self-antigens, with a breakdown of self-tolerance, resulting in autoimmune disease.
Introduction: Diabetes mellitus is a condition whose main characteristic is excessive blood glucose and, if not controlled, can cause chronic systemic complications such as, nephropathy, pulmonary dysfunction, retinopathy and vascular disorders, among others. Lung complications in diabetics, due to chronic hyperglycemia, have been studied more recently. Objective: This study aims to conduct a literature review on changes in lung function in diabetes mellitus, through an integrative bibliographical review. Method: Bibliographic survey, through an integrative literature review, to establish a correlation between glycemic control and lung function in diabetic subjects. The integrative review was made by searching the Medline international databases for review of manuscripts. Selection of these databases was based on the wide range of journals covered by each of them and our goal was to provide an overview of the scientific production devoted to the topic over the timeframe of analysis. The following inclusion criteria were considered during the review: use of the keywords “lung” OR “pneumopathy” OR “lung disease” MeSH “diabetes mellitus” entered into the search form, and availability of an abstract in English. Results: A total 12 scientific productions were selected by contain information about the pulmonary function alterations in diabetes. Conclusion: The main pulmonary function abnormalities found in diabetics are: lung volume reduction; lung elasticity reduced; capillary blood volume reduction; thickening of the capillary basement membrane; decrease in muscle strength; and paresis or bilateral diaphragmatic paralysis due to phrenic neuropathy.
