Large differences in COVID‐19 death rates exist between countries and between regions of the same country. Some very low death rate countries such as Eastern Asia, Central Europe or the Balkans have a common feature of eating large quantities of fermented foods. Although biases exist when examining ecological studies, fermented vegetables or cabbage were associated with low death rates in European countries. SARS‐CoV‐2 binds to its receptor, the angiotensin converting enzyme 2 (ACE2). As a result of SARS‐Cov‐2 binding, ACE2 downregulation enhances the angiotensin II receptor type 1 (AT 1 R) axis associated with oxidative stress. This leads to insulin resistanceas well as lung and endothelial damage, two severe outcomes of COVID‐19. The nuclear factor (erythroid‐derived 2)‐like 2 (Nrf2) is the most potent antioxidant in humans and can block the AT 1 R axis. Cabbage contains precursors of sulforaphane, the most active natural activator of Nrf2. Fermented vegetables contain many lactobacilli, which are also potent Nrf2 activators. Three examples are given: Kimchi in Korea, westernized foods and the slum paradox. It is proposed that fermented cabbage is a proof‐of‐concept of dietary manipulations that may enhance Nrf2‐associated antioxidant effects helpful in mitigating COVID‐19 severity.
In our sample of patients with severe asthma, those who were obese were more likely to have uncontrolled asthma than patients with a normal BMI. Nevertheless, this is not conclusive evidence for a direct causal association between obesity and poor asthma control. Future studies are necessary to dissect the relationship between obesity and asthma outcomes.
Objective: To evaluate the use of inhaler devices by patients with severe asthma treated via the Programa para o Controle da Asma e Rinite Alérgica na Bahia (ProAR, Bahia State Asthma and Allergic Rhinitis Control Program), recording the frequency of their errors in performing key steps and the relationship between such errors and the lack of asthma control. Methods: A cross-sectional study involving 467 patients enrolled in the ProAR in the city of Salvador, Brazil. The devices evaluated were metered dose inhalers (MDIs), with or without a spacer, and dry powder inhalers (DPIs; Pulvinal ® or Aerolizer ® ). For the assessment of the inhalation technique, a checklist was used; the patients were asked to demonstrate the technique so that an interviewer could observe all of the steps performed. For the assessment of asthma control, we used the 6-item asthma control questionnaire. Results: Most of the patients showed appropriate inhalation techniques when using the devices. When using an MDI, few patients made mistakes in the key step of "coordinating activation and inhalation" (5.2% and 9.1% with and without the use of a spacer, respectively). During Pulvinal ® use, 39% of the patients did not inhale quickly and deeply, compared with only 5.8% during Aerolizer ® use. Of the patients that made use of Aerolizer ® alone, 71.3% appropriately performed all of the essential steps, and their asthma was controlled. Conclusions: Most of the patients in this sample, all of whom had been submitted to periodic checks of their inhalation technique (as part of the program), used the devices appropriately. Proper inhalation technique is associated with asthma symptom control.Keywords: Asthma; Administration, inhalation; Metered dose inhalers; Dry powdered inhalers. ResumoObjetivo: Avaliar o manuseio dos dispositivos pelos asmáticos graves acompanhados no Programa para o Controle da Asma e Rinite Alérgica na Bahia (ProAR), registrando a frequência dos seus erros em passos essenciais e a relação desses com a falta de controle da asma. Métodos: Estudo de corte transversal com 467 pacientes em acompanhamento no ProAR, na cidade de Salvador (BA). Os dispositivos avaliados foram inalador dosimetrado (ID), em isolado ou com espaçador, e inalador de pó seco (IPS; Pulvinal ® ou Aerolizer ® ). A avaliação da técnica inalatória foi realizada através de uma lista de verificação, sendo solicitado ao paciente que demonstrasse o uso para que um entrevistador observasse todos os passos realizados. Para a avaliação do controle da asma, utilizou-se o questionário de controle da asma com seis questões. Resultados: A maioria dos pacientes demonstrou técnicas inalatórias adequadas no uso dos dispositivos. Poucos erros foram observados na etapa essencial "coordenar disparo e inspiração" no uso de ID isolado e com espaçador (em 5,2% e em 9,1% dos pacientes, respectivamente). No uso de Pulvinal ® , 39% dos pacientes não realizaram uma inspiração rápida e profunda, comparados a somente 5,8% no uso de Aerolizer ® . Dos pacientes que utilizavam ape...
Objective: To identify the contribution of all the dimensions involved in job insecurity among nursing professionals in Brazilian state public hospitals. Method: This was a quantitative descriptive study conducted between March 2015 and February 2016, with nurses, nursing technicians and nursing aides. The data were analyzed using exploratory factor analysis. Results: The sample consisted of 265 nurses (n=161 with job security and n=104 outsourced) and 810 nursing technicians and nursing aides (n=597 with job security and n=213 outsourced). Among the nurses, “Working conditions” accounted for 46.8% of their job insecurity. Among nursing technicians and nursing aides “intensity of work due to work process organization” best explained the construct of job insecurity (51.2%). Conclusion: Job insecurity is expressed differently depending on the type of nursing professional. The difference in the distribution of the dimensions showed that job insecurity is related to the hierarchical position of each nursing professional in the technical division of nursing work and the role of each professional in the work process.
