Contributions of mean and shape of blood pressure distribution to worldwide trends and variations in raised blood pressure: A pooled analysis of 1018 population-based measurement studies with 88.6 million participants

© The Author(s) 2018. Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the contributions of these two phenomena to the worldwide trends in the prevalence of raised blood pressure. Methods: We pooled 1018 population-based studies with blood pressure measurements on 88.6 million participants from 1985 to 2016. We first calculated mean systolic blood pressure (SBP), mean diastolic blood pressure (DBP) and prevalence of raised blood pressure by sex and 10-year age group from 20-29 years to 70-79 years in each study, taking into account complex survey design and survey sample weights, where relevant. We used a linear mixed effect model to quantify the association between (probittransformed) prevalence of raised blood pressure and age-group- and sex-specific mean blood pressure. We calculated the contributions of change in mean SBP and DBP, and of change in the prevalence-mean association, to the change in prevalence of raised blood pressure. Results: In 2005-16, at the same level of population mean SBP and DBP, men and women in South Asia and in Central Asia, the Middle East and North Africa would have the highest prevalence of raised blood pressure, and men and women in the highincome Asia Pacific and high-income Western regions would have the lowest. In most region-sex-age groups where the prevalence of raised blood pressure declined, one half or more of the decline was due to the decline in mean blood pressure. Where prevalence of raised blood pressure has increased, the change was entirely driven by increasing mean blood pressure, offset partly by the change in the prevalence-mean association. Conclusions: Change in mean blood pressure is the main driver of the worldwide change in the prevalence of raised blood pressure, but change in the high-blood-pressure tail of the distribution has also contributed to the change in prevalence, especially in older age groups

ATLANTIC-PRIMATES: a dataset of communities and occurrences of primates in the Atlantic Forests of South America

Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, and emerging infectious diseases. There are 26 primate species in the Atlantic Forests of South America, 19 of them endemic. We compiled a dataset of 5,472 georeferenced locations of 26 native and 1 introduced primate species, as hybrids in the genera Callithrix and Alouatta. The dataset includes 700 primate communities, 8,121 single species occurrences and 714 estimates of primate population sizes, covering most natural forest types of the tropical and subtropical Atlantic Forest of Brazil, Paraguay and Argentina and some other biomes. On average, primate communities of the Atlantic Forest harbor 2 ± 1 species (range = 1–6). However, about 40% of primate communities contain only one species. Alouatta guariba (N = 2,188 records) and Sapajus nigritus (N = 1,127) were the species with the most records. Callicebus barbarabrownae (N = 35), Leontopithecus caissara (N = 38), and Sapajus libidinosus (N = 41) were the species with the least records. Recorded primate densities varied from 0.004 individuals/km 2 (Alouatta guariba at Fragmento do Bugre, Paraná, Brazil) to 400 individuals/km 2 (Alouatta caraya in Santiago, Rio Grande do Sul, Brazil). Our dataset reflects disparity between the numerous primate census conducted in the Atlantic Forest, in contrast to the scarcity of estimates of population sizes and densities. With these data, researchers can develop different macroecological and regional level studies, focusing on communities, populations, species co-occurrence and distribution patterns. Moreover, the data can also be used to assess the consequences of fragmentation, defaunation, and disease outbreaks on different ecological processes, such as trophic cascades, species invasion or extinction, and community dynamics.

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest. No copyright restrictions are associated with the data set. Please cite this Ecology Data Paper if the data are used in publication and teaching events. © 2019 The Authors.

Worldwide trends in hypertension prevalence and progress in treatment and control from 1990 to 2019: a pooled analysis of 1201 population-representative studies with 104 million participants

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

Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight NCD Risk Factor Collaboration (NCD-RisC)

From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions

Escherichia coli verotoxigênica: isolamento e prevalência em 60 propriedades de bovinos de leite da região de Pelotas, RS, Brasil Verotoxin-producing Escherichia coli: isolation and prevalence in 60 dairy cattle farms from Pelotas-RS, Brazil

A produção de verotoxinas foi investigada em 1.127 isolamentos de Escherichia coli feitos a partir de 243 bovinos de leite, de água de consumo humano e animal e de amostras de leite de 60 propriedades da bacia leiteira de Pelotas, no período de dezembro de 1999 a dezembro de 2000, com o objetivo de determinar a prevalência de E. coli verotoxigênicas (VTEC) nas propriedades e no rebanho, de detectar a presença de sorotipos ligados a infecções humanas e de identificar, nas propriedades e na região de Pelotas, potenciais fatores de risco de infecção para os animais. A detecção das toxinas em sobrenadante de culturas de E. coli isoladas foi realizada através do ensaio de citotoxicidade em células Vero. VTEC foi isolada em 95% (57/60) das propriedades estudadas, em 49% (119/243) dos animais testados, em 5% (3/60) das amostras de água de consumo humano, em 8,35% (5/60) das amostras de água de consumo animal e em 5% (3/60) das amostras de leite. A prevalência de bovinos infectados em cada propriedade variou de 0 a 100%. Em 2,9% (7/243) dos animais testados, foram isoladas VTEC pertencentes aos sorogrupos O157, O91 e O112, que incluem cepas responsáveis por casos de colite hemorrágica e síndrome urêmica hemolítica em humanos. Fatores de risco de contaminação, como a precipitação pluviométrica, a temperatura, o tamanho da propriedade e a concentração de animais, apresentaram evidências de influenciarem a prevalência de VTEC nos animais. Estes resultados sugerem que o grupo VTEC está amplamente distribuído na bacia leiteira de Pelotas e inclui organismos pertencentes a sorogrupos patogênicos para humanos.<br>The production of verotoxin was investigated in 1127 Escherichia coli isolated from 243 dairy cattle, water for human and animal consumption, and milk samples from 60 dairy farms from Pelotas-Brazil, from December of 1999 to December of 2000, to determine the prevalence of verotoxigenic E. coli (VTEC) in farms, to detect the presence of serotypes involved in human infections and to identify potential risk factors for animal infection. Vero cell assay was used to detect toxins in culture supernatants from E. coli isolated. VTEC was isolated in 95% (57/60) from farms and in 49% (119/243) from cattle, 5% (3/60) from water of human consumption, in 8.35% (5/60) from water animal consumption and 5% (3/60) from milk samples. The prevalence of cattle infected for each farm ranged from 0 to 100%. VTEC belonging to serogroups O157, O91 and O112, which include strains responsible for cases of hemorrhagic colitis and hemolytic uremic syndrome in humans, were isolated from 7 (2.9%) out of 243 cattle. Risk factors for contamination, such as amount of rain, farm size and cattle number, influenced cattle prevalence rate. These results suggest that VTEC is widely distributed among dairy cattle in the region surveyed and includes organisms from serogroups pathogenic for humans

Para além da ordem: o cotidiano prisional da Bahia oitocentista a partir da correspondência de presos Beyond order: daily prison life in Nineteenth-Century Bahia according to prisoners' correspondence

Este artigo tem o objetivo de discutir a comunidade prisional na Bahia Oitocentista, a partir das correspondências de presos. Faço uma análise dessa documentação buscando reconstruir parte do cotidiano dos presos, pressupondo a existência de uma ordem paralela, com igual ou maior força do que a oficial, mas que não anulava a arbitrariedade e a violência desta última. Entretanto, essa ordem paralela podia ser rompida, a qualquer momento, seja por confrontos diretos entre os próprios presos ou entre os presos e os funcionários da prisão. Dentre os tipos de protesto, a escrita foi um dos mais utilizados pelos presos e, dependendo da estratégia sugerida nas cartas, era possível conquistar espaços sem romper com a ordem prisional. O recurso à escrita foi utilizado por presos, letrados ou não, de diferentes condições jurídicas - escravos, libertos e livres -, independentemente do tipo de pena que estivessem cumprindo.<br>The aim of this article is to discuss the prison community in Bahia during the 19th century, using the correspondence written by prisoners. I analyze this documentation in an attempt to reconstruct the daily life of the prisoners, presupposing the existence of a parallel order equal to or more powerful than the official prison order, but that did not end the arbitrariness and the violence of the latter. This parallel order could be broken any moment, whether because of direct confrontation among the prisoners themselves, or due to confrontation between prisoners and prison staff. Among different types of protest, writing was widely used by prisoners and, depending on the strategy suggested in the letters, it was possible to obtain gains without breaking the prison order. Written appeals were used by prisoners, educated or not, of different legal conditions, slaves, freed and free, independent of the type of sentence they were serving
