ABSTRACT BACKGROUND: The speed of the spread of coronavirus disease 2019 (COVID-19) has put enormous pressure on hospitals and other healthcare facilities. This, together with blockages in several countries, has hindered the availability and accessibility of the necessary personal protective equipment (PPE). OBJECTIVE: To identify, systematically evaluate and summarize the available scientific evidence on the efficacy, safety, safe use and reuse of PPE for healthcare professionals, for preventing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. DESIGN AND SETTING: Systematic review of studies analyzing products for disinfecting and enabling reuse of PPE for coronavirus within the evidence-based health program of a federal university in São Paulo (SP), Brazil. METHODS: A systematic search of the relevant literature was conducted in the PubMed, EMBASE, Cochrane Library, CINAHL, SCOPUS, Web of Science and LILACS databases, for articles published up to November 30, 2020. RESULTS: Ten studies were selected. These analyzed the use of N95, surgical and cotton masks, face shields, flexible enclosures with plastic covers or polycarbonate intubation boxes and plastic curtains; and also PPE disinfection using several substances. CONCLUSION: Combined use of a face shield with a N95 mask proved to be superior to other associations for protecting healthcare workers. Some products are useful for disinfecting PPE, such as 70% ethanol, 0.1% sodium hypochlorite and a mixture of quaternary ammonium and H2O2, and hydrogen peroxide. Ultraviolet light and dry heat at 70 °C can be used to decontaminate N95 masks. REGISTRATION NUMBER: DOI: 10.17605/OSF.IO/4V5FD at the OPENSCIENCE Framework.

ABSTRACT BACKGROUND: Rheumatoid arthritis (RA) is a chronic disease with higher prevalence among women aged between 30 and 50 years and general prevalence of 1% worldwide. Interventions promoting improvement of quality of life for individuals with RA are required. Tai Chi appears to be a low-cost alternative, with studies showing positive results from this technique. However, regarding aspects of RA such as pain and sensitivity, studies remain inconclusive. OBJECTIVES: To compare the effectiveness of the Tai Chi method for treating patients diagnosed with rheumatoid arthritis, among systematic reviews. DESIGN AND SETTING: Overview of systematic reviews with Cochrane and non-Cochrane methodology. METHODS: Systematic reviews involving quasi-randomized and randomized clinical trials (RCTs) on use of Tai Chi, with no restrictions regarding the date and language of publication, were included. RESULTS: Three systematic reviews were included. The effects of Tai Chi associated with education and stretching exercises versus education and stretching were evaluated in these reviews. They showed that improvements in the variables of mood, depression and functional index were associated with use of Tai Chi. CONCLUSIONS: The findings suggest that clinical improvement was achieved, although not statistically significant with regard to pain and disease pattern, as assessed using the ACR20 measurement. Improvements relating to disability and quality of life were also seen. There was a low level of evidence and therefore caution in data analysis is recommended. The three studies included showed poor reliability for providing an accurate and complete summary of use of Tai Chi among people diagnosed with rheumatoid arthritis. PROSPERO: CRD42019125501.

Abstract Background: Diet plays a critical role in Systemic Lupus Erythematosus (SLE) patients, impacting on the microbiota composition and, consequently, on the immune response. The objective was to analyze and verify the diet effect on SLE patients. Methods: This is a systematic review performed at the Evidences-based Health Lab, Escola Superior em Ciências da Saúde, Brasília (DF), Brazil. In March, 2021, five databases, and grey literature, through JSTOR, Open Grey, and Google Scholar were searched. Randomized Clinical Trials in which SLE patients with calorie restricted, low glycemic index or other diet involving the joint adequacy of these aspects, compared with placebo or different types of diet, were included. Results: It was identified in the databases 758 articles; 132 were duplicated; 616 references were screened, and 604 were excluded. After reading the title and abstract, 12 articles were included for full-text reading. After the full-text reading, three studies were included for quantitative analysis. The diet improved the quality of life at 6 (MD 16.30; 5.91;26.69) and 12 weeks (MD 14.60; 0.88;28.32). The GRADE was used to evaluate the quality of evidence. Conclusion: There is low evidence that the diet has a positive impact on the quality of life of SLE patients. Trial registration PROSPERO—CRD4202012208.

ABSTRACT BACKGROUND: Faced with a pandemic, all healthcare actions need to reflect best practices, in order to avoid high transmissibility, complications and even hospitalizations. For hospital environments, the products recommended and authorized by regulatory institutions for environmental cleaning and disinfection need to be highly effective. OBJECTIVE: To identify, systematically evaluate and summarize the best available scientific evidence on environmental cleaning to prevent COVID-19 infection. DESIGN AND SETTING: A systematic review of studies analyzing cleaning products that inactivate coronavirus, conducted within the evidence-based health program of a federal university in São Paulo (SP), Brazil. METHODS: A systematic search of the relevant literature was conducted in the PubMed, EMBASE, Cochrane Library, CINAHL and LILACS databases, for articles published up to May 27, 2020, relating to studies evaluating cleaning products that inactivate coronavirus in the environment. RESULTS: Seven studies were selected. These analyzed use of 70% alcohol, detergent, detergent containing iodine, household bleach, sodium hypochlorite, hydrogen peroxide, chlorine dioxide, glutaraldehyde, ultraviolet irradiation and plasma air purifier. The effectiveness of treating sewage with sodium hypochlorite and chlorine dioxide was also evaluated. CONCLUSION: Disinfection of environments, especially those in ordinary use, such as bathrooms, needs to be done constantly. Viral inactivation was achieved using chlorine-based disinfectants, alcohol, detergents, glutaraldehyde, iodine-containing detergents, hydrogen peroxide compounds and household bleaches. Alcohol showed efficient immediate activity. In sewage, sodium hypochlorite had better action than chlorine dioxide. REGISTRATION NUMBER: DOI: 10.17605/OSF.IO/YC5P4 in the Open Science Framework.

ABSTRACT BACKGROUND: Shoulder pain is considered to be the third largest cause of musculoskeletal functional alterations in individuals presenting pain during movement. OBJECTIVE: The purpose of this synthesis of evidence was to identify the clinical effectiveness of conservative and surgical treatments reported in Cochrane systematic reviews among individuals diagnosed with rotator cuff disease. DESIGNAND SETTING: Review of systematic reviews, conducted in the Federal University of São Paulo (Universidade Federal de São Paulo, UNIFESP). METHODS: This synthesis of evidence included systematic reviews that had been published in the Cochrane database. The inclusion criteria were that these systematic reviews should involve individuals aged ≥ 16 years with rotator cuff disease, comparing surgical procedures with or without associated nonsurgical procedures versus placebo, no treatment or other nonsurgical interventions. RESULTS: Thirty-one systematic reviews were included, involving comparisons between surgical procedures and conservative treatment; procedures either combined or not combined with drugs, versus other procedures; and procedures involving exercises, manual therapy and electrothermal or phototherapeutic resources. CONCLUSIONS: The findings suggest that strengthening exercises, with or without associated manual therapy techniques and other resources, were the interventions with greatest power of treatment over the medium and long terms, for individuals with shoulder pain. These had greater therapeutic power than surgical procedures, electrotherapy or photobiomodulation. Protocol registration number in the PROSPERO database: ID - CRD42018096578.

OBJETIVO: Avaliar o efeito de um programa de treinamento de força muscular progressiva e sensório-motor, no equilíbrio e na redução do risco de quedas em mulheres com osteoporose. MÉTODO: Foram selecionadas 82 mulheres sedentárias com idade entre 60 e 75 anos com osteoporose, randomizadas em dois grupos: grupo intervenção, composto por 41 pacientes submetidas a 18 semanas de treinamento de força muscular progressiva do quadríceps (a 50%, 60%, 70% até 80% de 1-RM - uma repetição máxima), e de propriocepção, associado ao tratamento clínico medicamentoso para osteoporose; e grupo controle, também composto por 41 pacientes que receberam apenas o tratamento clínico medicamentoso. O equilíbrio e o risco de quedas foram avaliados por meio da Escala de Equilíbrio de Berg (BBS) e do cálculo do Índice de Quedas (IQ). O número de quedas foi avaliado seis meses antes do início da pesquisa e nos seis meses seguintes. RESULTADOS: 69 pacientes concluíram a pesquisa. O programa promoveu melhora no equilíbrio funcional (p<0,001) demonstrado pela BBS, redução do risco de quedas calculado pelo escore geral do IQ (p<0,004) e ainda uma redução do número total de quedas, que no grupo experimental foram significativamente menores que no grupo controle (p<0,001). CONCLUSÃO: A associação do treinamento de força progressiva para quadríceps e propriocepção é eficaz na prevenção de quedas e redução de seus fatores de risco, e o modelo para previsão quantitativa do risco de quedas pode ser útil na identificação do risco de quedas em pessoas idosas.

OBJECTIVE: This study aims to evaluate the effect of progressive muscular strength and proprioception training program on the balance and decrease in the risk of falls in women with osteoporosis. METHOD: 82 sedentary women aged 60-75 years with osteoporosis were selected and randomized in two groups: the intervention group comprised 41 patients submitted to an 18-week progressive muscular strength and proprioception training of quadriceps associated to drug therapy for osteoporosis; and control group, formed by 41 patients submitted to drug therapy only. The balance and fall risk were evaluated using the Balance Berg Scale (BBS) and calculating the Fall Index (FI). The number of fall was assessed six months before the research and the following six months. RESULTS: 69 patients completed the research. The program improved the functional balance (p<0.001) shown by BBS, decreased the risk of falls evidenced by the general score of FI (p<0.004) and also a decrease in the total number of falls. The experimental group showed significant lower number of falls when compared to the control group (p<0.001). CONCLUSION: The association of progressive strength of quadriceps and proprioceptive training is effective to prevent falls and reduce risk factors. The quantitative model to predict risk of falls might be useful to identify the risk of falls in the elderly. Trial registration: 082213-ANZCTR.

CONTEXT AND OBJECTIVE: Electrical stimulation (ES) is widely used to strengthen muscles following ligament and meniscal injuries. The aim of this study was to evaluate the effectiveness of ES for rehabilitation after soft tissue injuries of the knee treated surgically or conservatively. DESIGN AND SETTING: Systematic review at the Brazilian Cochrane Center. METHODS: We searched the Cochrane Central Register of Controlled Trials (2010, Issue 12), Medline (Medical Analysis and Retrieval System Online) via PubMed (1966 to December 2010), Embase (Excerpta Medica database, 1980 to December 2010), Lilacs (Literatura Latino-Americana e do Caribe em Ciências da Saúde, 1982 to December 2010), and PEDro (Physiotherapy Evidence Database, 1929 to December 2010). The studies included were randomized controlled trials using ES to increase muscle strength for rehabilitation of patients with soft tissue injuries of the knee. Two authors independently evaluated studies for inclusion and performed data extraction and methodological quality assessment. RESULTS: Seventeen studies evaluating ES after anterior cruciate ligament reconstruction and two studies evaluating ES after meniscectomy were included. There was a statistically significant improvement in quadriceps strength through ES (mean difference, MD: -32.7; 95% confidence interval, CI: -39.92 to -25.48; n = 56) and in functional outcomes (MD -7; -12.78 to -1.22; n = 43) six to eight weeks after surgical reconstruction of the anterior cruciate ligament. CONCLUSION: There is evidence that ES coupled with conventional rehabilitation exercises may be effective in improving muscle strength and function two months after surgery
