COVID-19 Lockdown and the Behavior Change on Physical Exercise, Pain and Psychological Well-Being: An International Multicentric Study.

OBJECTIVE: To evaluate the impact of the COVID-19 pandemic and the following lockdown on physical exercise (PEx) practice, pain, and psychological well-being. METHODS: A cross-sectional multicentric study was performed using a nonrandom convenience sampling from the general population (≥18 years-old) of 6 countries (Brazil, Italy, France, Portugal, Germany, and Spain) adopting social isolation (SI). The validated self-administered online survey (PEF-COVID19) was used. The tests T-test and Chi-square with Bonferroni correction were used for statistical analysis and a multivariate logistic regression model (p ˂ 0.05). RESULTS: We included 3194 replies and ~80% of the respondents were in SI. Brazilian sample was highly influenced by the pandemic considering PEx practice and habits, pain, anxiety, and stress (p ˂ 0.05). Among the European countries, Italy presented the major changes. The model to predict the non-practice of PEx during SI showed that the variables countries, smoking, SI, and PEx level were significant predictors (p ˂ 0.001). CONCLUSION: The pandemic changed the PEx practice and habits, and the psychological well-being of populations in different manners. Countries, smoking, SI, and PEx level were predictors for the non-practice of PEx. Public health strategies are suggested to avoid sedentary lifestyles and quality of life decrease.

Máquina de perfusão versus armazenamento estático na preservação renal de doadores com morte encefálica: revisão sistemática e metanálise / Machine perfusion versus cold storage in renal preservation of deceased donors with brain death: systematic review and meta-analysis

RESUMO Com a utilização crescente da máquina de perfusão no transplante renal, tem sido constatado que a isquemia dinâmica correlaciona-se à melhora da preservação orgânica. Nesse contexto, realizamos uma revisão sistemática que procurou avaliar a eficácia do uso de máquina de perfusão portátil (LifePort Kidney Transporter Machine®), utilizada no Brasil, comparada ao armazenamento estático, no que tange à função retardada do transplante renal de doadores com morte encefálica. Foi efetuada pesquisa bibliográfica, nas bases LILACS, MEDLINE via PubMed, Scopus, Clarivate Analytics, Cochrane Library, Embase, SciELO, além de busca manual no Google acadêmico. A revisão sistemática, finalizada em abril 2017, foi constituída somente por ensaios clínicos randomizados. Para metanálise, foram avaliadas Razão de Risco e Razão de Chance. Foram identificados 86 documentos e selecionados, ao final, dois artigos com critérios de elegibilidade para metanálise, de grupos europeus e brasileiros. Nestes, 374 rins foram alocados para a máquina de perfusão, e igual número para o armazenamento estático. A função retardada do enxerto foi constatada em 84 e 110 pacientes, respectivamente. Na metanálise, foram obtidas uma Razão de Risco de 0,7568 (p=0,0151) e uma Razão de Chance de 0,6665 (p=0,0225), ambas com intervalo de confiança de 95%. A máquina de perfusão reduziu a incidência de função retardada do enxerto de doadores com morte encefálica.

ABSTRACT With the increasing use of machine perfusion in kidney transplantation, it has been observed that dynamic ischemia correlates with the improvement of organ preservation. In this context, we performed a systematic review that aimed to evaluate the efficacy of the portable machine perfusion (LifePort Kidney Transporter Machine®), used in Brazil, compared to cold storage, regarding the delayed graft function of deceased donors with brain death. Literature search was carried out in LILACS, MEDLINE via PubMed, Scopus, Clarivate Analytics, Cochrane Library, Embase, and SciELO, as well as in Google Scholar manually. The systematic review consisted only of randomized clinical trials. For meta-analysis, relative risk and odds ratio were evaluated. Eighty-six documents were identified and two papers from European and Brazilian groups were selected at the end, with eligibility criteria for meta-analysis. In these, 374 kidneys were assigned to machine perfusion and 374 kidneys were assigned to cold storage. Delayed graft function was observed in 84 and 110 patients, respectively. In meta-analysis, a risk ratio of 0.7568 (p=0.0151) and an odds ratio of 0.6665 (p=0.0225) were obtained, both with a 95% confidence interval. Machine perfusion reduced the incidence of delayed graft function of deceased donors with brain death.
