Workload assessment: cross-cultural adaptation, content validity and instrument reliability.

OBJECTIVES: to adapt, validate the content and assess the reliability of the instrument National Aeronautics and Space Administration - Task Load Index, translated into Brazilian Portuguese. METHODS: a methodological study, divided into five steps: translation; synthesis; back-translation; assessment of the Portuguese version by an expert committee; pre-test and content validity of the final version by health professionals working in inpatient units. The Content Validity Index (CVI) (minimum 0.80) and Cronbach's alpha (minimum 0.70) were calculated. RESULTS: in the first round, in the agreement analysis of the translated version, three items did not reach the minimum CVI value. It was decided to remove the statement. The instrument title and items "performance" and "effort" were changed. There was consensus and approval of the final version in the pre-test step. CONCLUSIONS: the NASA Task Load Index instrument, adapted to Brazilian Portuguese, presents reliability and content validity evidence.

Personal protective equipment implementation in healthcare: A scoping review.

BACKGROUND: Adherence to infection prevention and control (IPC) measures, including the proper use of protective personal equipment (PPE), in health care is complex and is influenced by many factors. Isolated interventions do not have the potential to achieve optimal PPE adherence and appropriate provision, leading to incomplete PPE implementation. OBJECTIVE: To map PPE implementation in health care with a focus on its barriers and facilitators. METHODS: A scoping review was conducted across 14 electronic databases using the Joanna Briggs Institute methodology. RESULTS: Seventy-four papers were included in the review. Findings were analyzed and synthesized into categories to match the Consolidated Framework for Implementation Research domains. The content was then synthesized into barriers for PPE implementation and interventions to address them. The main barriers were discomfort in clinical work; shortage, supply and logistics problems; inadequacies in facilities infrastructure, weakness in policies and communication procedures; and health workers' (HW) psychological issues and lack of preparedness. Implementation interventions reported were related to HW wellbeing assurance; work reorganization; IPC protocols; adoption of strategies to improve communication and HW training; and adoption of structural and organizational changes to improve PPE adherence. CONCLUSIONS: PPE implementation, which is critical IPC programs, involves multilevel transdisciplinary complexity. It relies on the development of context-driven implementation strategies to inform and harmonize IPC policy in collaboration with local and international health bodies.

Fatores associados ao sofrimento mental em pessoas com diabetes mellitus durante a pandemia da covid-19 / Factors associated with mental suffering in people with diabetes mellitus during the covid-19 pandemic / Factores asociados a la angustia mental en personas con diabetes mellitus durante la pandemia de covid-19

RESUMO Objetivo: analisar os fatores associados ao sofrimento mental em pessoas com diabetes mellitus durante a pandemia da COVID-19. Método: estudo transversal, realizado em duas comunidades virtuais brasileiras da plataforma Facebook, no período de agosto de 2020 a janeiro de 2021. A amostra totalizou 111 pessoas com diabetes. A avaliação das condições de saúde foi realizada por meio de formulário eletrônico, e para identificação do sofrimento mental foi utilizado o Self Report Questionnaire-20. Análises descritivas e inferenciais foram expressas por frequências e pela regressão logística simples e múltipla. Resultados: o sofrimento mental está associado à questão de ser do gênero feminino, ter histórico prévio de transtorno mental (depressão e ansiedade), diagnóstico de diabetes há mais de seis anos e à presença de complicações oftalmológicas, que potencializam as chances para instabilidades emocionais. Conclusão: o estudo oferece subsídios ao direcionamento de estratégias de suporte que minimizem os impactos psicossociais da pandemia na pessoa com diabetes.

ABSTRACT Objective: to analyze the factors associated with mental distress in people with diabetes mellitus during the COVID-19 pandemic. Method: cross-sectional study, conducted in two Brazilian virtual communities of the Facebook platform, in the period from August 2020 to January 2021. The sample totaled 111 people with diabetes. The evaluation of health conditions was performed using an electronic form, and the Self Report Questionnaire-20 was used to identify mental suffering. Descriptive and inferential analyses were expressed by frequencies and simple and multiple logistic regression. Results: mental suffering is associated with being female, having a previous history of mental disorders (depression and anxiety), having been diagnosed with diabetes for more than six years, and the presence of ophthalmologic complications, which increase the chances of emotional instability. Conclusion: the study offers subsidies to the direction of support strategies that minimize the psychosocial impacts of the pandemic on people with diabetes.

Acute kidney injury caused by venomous animals: inflammatory mechanisms.

Either bites or stings of venomous animals comprise relevant public health problems in tropical countries. Acute kidney injury (AKI) induced by animal toxins is related to worse prognostic and outcomes. Being one the most important pathways to induce AKI following envenoming due to animal toxins, inflammation is an essential biological response that eliminates pathogenic bacteria and repairs tissue after injury. However, direct nephrotoxicity (i.e. apoptotic and necrotic mechanisms of toxins), pigmenturia (i.e. rhabdomyolysis and hemolysis), anaphylactic reactions, and coagulopathies could contribute to the renal injury. All these mechanisms are closely integrated, but inflammation is a distinct process. Hence, it is important to improve our understanding on inflammation mechanisms of these syndromes to provide a promising outlook to reduce morbidity and mortality. This literature review highlights the main scientific evidence of acute kidney injury induced by bites or stings from venomous animals and their inflammatory mechanisms. It included observational, cross-sectional, case-control and cohort human studies available up to December 2019. Descriptors were used according to Medical Subject Headings (MeSH), namely: "Acute kidney injury" or "Venom" and "Inflammation" on Medline/Pubmed and Google Scholar; "Kidney disease" or "Acute kidney injury" on Lilacs and SciELO. The present review evidenced that, among the described forms of renal inflammation, it can occur either directly or indirectly on renal cells by means of intravascular, systemic and endothelial hemolysis, activation of inflammatory pathway, as well as direct action of venom cytotoxic components on kidney structures.

Acute and subacute (28 days) toxicity of green coffee oil enriched with diterpenes cafestol and kahweol in rats.

Green coffee oil enriched with cafestol and kahweol was obtained by supercritical fluid extraction using carbon dioxide while its safety and possible effects from acute and subacute treatment were evaluated in rats. For acute toxicity study, single dose of green coffee oil (2000 mg/kg) was administered by gavage in female rats. For subacute study (28 days), 32 male rats received different doses of green coffee oil extract (25, 50, and 75 mg/kg/day). In the acute toxicity study, main findings of this treatment indicated no mortality, body weight decrease, no changes in hematological and biochemical parameters, and relative weight increase in heart and thymus, without histopathological alterations in all assessed organs. All these findings suggest that LD50 is higher than aforesaid dose. In the subacute toxicity, main findings showed body weight decrease mainly at the highest dose without food consumption change, serum glucose and tryglicerides levels decrease, and relative weight increase in liver. As evidenced in histopathological pictures, no changes were observed at all treated doses. Our study suggest that green coffee oil can be explored to clinically develop new hypocholesteromic and hypoglycemic agents. However, further studies evaluating long-term effects are needed in order to have sufficient safety evidence for its use in humans.
