    Praias de enseada tendem a ter sua forma em planta em equilíbrio estático quando as ondas incidentes mais frequentes são controladas pelo processo de difração em torno dos promontórios que as limitam. Este equilíbrio é interrompido com a alteração do ponto de difração, como no caso de implementação de estruturas rígidas. O artigo apresenta um estudo de caso realizado na praia de Itaipava, localizada no distrito de Itapemirim, Espírito Santo, Brasil, onde foi construído um quebra-mar com a finalidade de ampliar a capacidade de suporte portuário nesta localidade. O estudo teve como objetivo reconstituir a evolução morfológica da praia e discutir os efeitos morfodinâmicos decorrentes da implementação do quebra-mar. Os métodos utilizados incluíram a superposição de imagens aéreas na determinação da evolução da linha de costa nas últimas 4 décadas (1970-2013). A partir da aplicação do modelo parabólico de enseada baseado em Hsu e Evans (1989), da análise dos dados de ondas e de perfis de praia foi possível compreender as alterações ocorridas ao longo dessa porção do litoral. O estudo concluiu que após a construção das estruturas ocorreram significativas mudanças na planta da praia. Os resultados indicaram que a porção norte da praia, sob efeito direto das intervenções, encontrava-se em equilíbrio estático antes da intervenção, contudo agora encontra-se na condição de equilíbrio dinâmico, com intensificação da deriva longitudinal, retirada e transporte de sedimentos da porção central da praia rumo ao porto. Desta forma, tanto o recuo da porção central quanto a sedimentação na porção protegida da praia prejudicaram as atividades econômicas da região, como o turismo e a pesca. Já o setor sul manteve sua tendência à progradação. A aplicação do modelo parabólico de planta de enseadas e a análise de dados morfodinâmicos permitiram compreender como se deu o processo adaptativo, e poderiam ter sido utilizados antes da intervenção no sentido de prever as consequências.</p

    BACKGROUND: Hypertension can be detected at the primary health-care level and low-cost treatments can effectively control hypertension. We aimed to measure the prevalence of hypertension and progress in its detection, treatment, and control from 1990 to 2019 for 200 countries and territories. METHODS: We used data from 1990 to 2019 on people aged 30-79 years from population-representative studies with measurement of blood pressure and data on blood pressure treatment. We defined hypertension as having systolic blood pressure 140 mm Hg or greater, diastolic blood pressure 90 mm Hg or greater, or taking medication for hypertension. We applied a Bayesian hierarchical model to estimate the prevalence of hypertension and the proportion of people with hypertension who had a previous diagnosis (detection), who were taking medication for hypertension (treatment), and whose hypertension was controlled to below 140/90 mm Hg (control). The model allowed for trends over time to be non-linear and to vary by age. FINDINGS: The number of people aged 30-79 years with hypertension doubled from 1990 to 2019, from 331 (95% credible interval 306-359) million women and 317 (292-344) million men in 1990 to 626 (584-668) million women and 652 (604-698) million men in 2019, despite stable global age-standardised prevalence. In 2019, age-standardised hypertension prevalence was lowest in Canada and Peru for both men and women; in Taiwan, South Korea, Japan, and some countries in western Europe including Switzerland, Spain, and the UK for women; and in several low-income and middle-income countries such as Eritrea, Bangladesh, Ethiopia, and Solomon Islands for men. Hypertension prevalence surpassed 50% for women in two countries and men in nine countries, in central and eastern Europe, central Asia, Oceania, and Latin America. Globally, 59% (55-62) of women and 49% (46-52) of men with hypertension reported a previous diagnosis of hypertension in 2019, and 47% (43-51) of women and 38% (35-41) of men were treated. Control rates among people with hypertension in 2019 were 23% (20-27) for women and 18% (16-21) for men. In 2019, treatment and control rates were highest in South Korea, Canada, and Iceland (treatment >70%; control >50%), followed by the USA, Costa Rica, Germany, Portugal, and Taiwan. Treatment rates were less than 25% for women and less than 20% for men in Nepal, Indonesia, and some countries in sub-Saharan Africa and Oceania. Control rates were below 10% for women and men in these countries and for men in some countries in north Africa, central and south Asia, and eastern Europe. Treatment and control rates have improved in most countries since 1990, but we found little change in most countries in sub-Saharan Africa and Oceania. Improvements were largest in high-income countries, central Europe, and some upper-middle-income and recently high-income countries including Costa Rica, Taiwan, Kazakhstan, South Africa, Brazil, Chile, Turkey, and Iran. INTERPRETATION: Improvements in the detection, treatment, and control of hypertension have varied substantially across countries, with some middle-income countries now outperforming most high-income nations. The dual approach of reducing hypertension prevalence through primary prevention and enhancing its treatment and control is achievable not only in high-income countries but also in low-income and middle-income settings.

    No full text
    PURPOSE: To describe the vascular and tissue histopathological changes in seven sequential experimental liver transplantations in pigs. METHODS: Fourteen female pigs, Sus domesticus species, with body mass between 5 and 8 kg were utilized. After the end of all anastomoses of the graft implantation in the receptor, the animal was monitored for 30 minutes, and at its end one of the biopsies was collected for histological analysis. The histological criteria utilized were: lytic hepatocyte necrosis, density of septal and portal inflammatory infiltrated, sinusoidal congestion and hemorrhage. The analysis was performed separately for the portal region in zone 1, 2 and 3. RESULTS: Among the structural changes undergone by the graft, those with greater frequency and intensity were vascular congestion and steatosis, which stood out in transplantations 5, 6 and 7. CONCLUSIONS: The technique demonstrated vascular alterations represented by vasocongestion, edema and minimum inflammatory reaction. In relation to the parenchyma, was observed macrovacuolar pan-acinar steatosis, focal lytic and occasional hemorrhages, beyond the accumulation of hemosiderin in Kuppfer's cells
