Are the coronavirus disease 2019(COVID-19)-themed applications launched during the pandemic sustainable? / 《全球健康杂志（英文）》

Many digital applications(Apps)were launched during the coronavirus disease 2019(COVID-19)pandemic for various purposes such as information sharing,risk assessment,self-management of symptoms,contact tracing,home monitoring,and decision making.Since the quality of CO VID-19-themed Apps varied and was less reliable based on measurements using the mobile Apps rating scale method,some of these Apps are considered useful while some are said to have the potential to harm users.This suggests the need for authorized institutions to validate and ensure the safety and security of these Apps before it was launched in public.This is necessary considering the potential dangers arising from App inaccuracies,as well as the potential misuse of user data due to data breaches.With these considerations in mind,we consider that the vaccine passport is an App with a COVID-19 theme that must be refined and applied sustainably amid the ongoing global crisis and the uncertainty of this pandemic.

O fluxo imigratório do distrito do Porto para o estado do Pará: borracha, conflitos, epidemias e gênero (1834-1930) / Immigration flux from the district of Porto to the state of Pará: rubber, conflicts, epidemics and gender (1834-1930) / El flujo migratorio del distrito de Oporto hacia el estado de Pará: caucho, conflictos, epidemias y género (1834-1930)

O artigo analisa a imigração do distrito do Porto, Portugal, para o estado do Pará, Brasil, entre 1834 e 1930, por meio dos registros de passaporte do Governo Civil do Porto. Observa-se o fluxo ao longo das décadas, ressaltando as questões econômicas e sociais que movimentaram esses deslocamentos, assim como aspectos pontuais, como epidemias e conflitos sociais, com destaque para a Revolta Cabana, em escala local, e a Primeira Guerra Mundial, em nível global. É analisada a influência dos acompanhantes dos titulares dos passaportes e da reemigração no fluxo de migrantes. Também investiga-se o perfil dos imigrantes quanto à origem e naturalidade por distrito e concelho português. Por fim, o artigo problematiza a migração feminina e as questões de gênero que a envolvem, apontando para a assimetria dos deslocamentos de mulheres, sempre em menor quantidade em relação aos homens, mas com crescimento nas primeiras décadas do século XX.

The article analyzes immigration from the Porto district to Pará, between 1834 and 1930, through passport records from the Civil Government of Porto. It observes the flow through the decades, emphasizing the economic and social issues associated to these displacements as well as specific aspects such as epidemics and social conflicts, highlighting the "Revolta da Cabanagem" (Cabanagem Rebellion) on a local scale and the First World War on a global scale. It analyzes the influence of passport holders' companions and re-migration on migrants' flows, followed by research into the profile of the immigrants regarding origin and the naturality by district and Portuguese "concelhos". Finally, the article problematizes female migration and the gender issues it involves, pointing to the asymmetry of women's displacement, always smaller in relation to men, but showing growth in the first decades of the twentieth century.

The research of hemoglobin mass on athletic biological passport for blood doping detection / 中国应用生理学杂志

OBJECTIVE@#To research the changes of blood parameters on different time points after micro-rHuEPO injection on young men and hope to provide evidences for Athletic Biological Passport (ABP) using in the detection of blood doping.@*METHODS@#Fourteen health young men were injected with micro-rHuEPO for 7 weeks, twice per one week.The subjects were treated with ferralia 105 mg every day during the injections.The control group was administrated with the same volume of saline solution injection and placebo 105 mg.The blood parameters (red blood cell, hemoglobin, reticulocyte, total hemoglobin, plasma volume, etc) were tested 11 times (7 days before the first injection, 3, 10, 17, 24, 31, 38 and 45 days after the first injection, 1, 2 and 3 weeks post the seventh week of last injection).By analyzed these total and concentration parameters, hope to know the effective of two kinds of parameters on ABP.@*RESULTS@#The levels of RBC and[Hb] were increased sharply after two weeks of injection and reached the peak in 5-6 weeks (9-10%, <0.01).It sustained till 3 weeks after the last injection.Total hemoglobin was increased significantly during the whole procedure of injections and reached the peak in week 5 (10%, <0.01) till 1 week after the last injection.Red blood cell volume was increased with the EPO injection and reached the peak in week 5 (<0.01), but blood volume wasn't increased significantly.Plasma volume was decreased with EPO injection and it was hemoconcentration.@*CONCLUSIONS@#It can enhance the total and concentration parameters through 7-week micro-rHuEPO injections and the total haemoglobin is more sensitive.So tHb can be used to detect blood doping in ABP.At the end of the last injection, the total blood parameters, such as the total hemoglobin, returned to normal, while the concentration index remained highly, possibly as a result of blood concentration.
