This paper provides the key elements to develop an integrated approach for measuring and monitoring city performance globally. The paper reviews the role of cities and why indicators are important. Then it discusses past approaches to city indicators and the systems developed to date, including the World Bank's initiatives. After identifying the strengths and weaknesses of past experiences, it discusses the characteristics of optimal indicators. The paper concludes with a proposed plan to develop standardized indicators that emphasize the importance of indicators that are measurable, replicable, potentially predictive, and most important, consistent and comparable over time and across cities. As an innovative characteristic, the paper includes subjective measures in city indicators, such as well-being, happy citizens, and trust.Cultural Policy,City Development Strategies,Cultural Heritage&Preservation,ICT Policy and Strategies,Housing&Human Habitats

Pharmacognostic study and in vitro activity on blood coagulation and platelet aggregation of leaves of Passiflora nitida Kunth (Passifloraceae)

The Passiflora genus (Passifloraceae) is mainly used to treat CNS and cardiovascular diseases. The Passiflora nitida Kunth species is commonly known as \x93maracujá-do-mato". The literature reports the in natura consumption of fruits of this species by the local population for gastrointestinal disorders. Considering the pharmacological potential of the genus, this work aimed to carry out study of phytochemical characterization of this species and study the effects of the aqueous (AE), ethanol (EE) and hexane (HE) extracts from its leaves on blood coagulation and platelet aggregation. Thin-layer chromatography and nuclear magnetic resonance were carried out for the phytochemical characterization. The effect of the extracts on the coagulation was evaluated by prothrombin time (PT) and activated partial thromboplastin time (aPTT) tests. The effect on the platelet aggregation was evaluated in platelet-rich plasma by spectrophotometric method, using adenosine diphosphate (ADP) and adrenaline (ADR) as inducers of aggregation. The AE, EE and HE extracts showed coagulant activity by the PT test, and the EE showed anticoagulant activity by the aPTT. When induced by ADP, the AE, EE and HE extracts showed 50% inhibitory concentration values (IC50, µg/mL) of 450.5 ± 50.7, 511.2 ± 35.5 and 394.4 ± 8.9, respectively, and when induced by ADR showed values of 438.7 ± 5.2, 21.0 ± 1.9 and 546.9 ± 49.9, respectively. The EE showed inhibitory effect on the aggregation. The phytochemical characterization was suggestive of the presence of flavonoids and coumarins, which can be attributed in part to the biological effects studied.O gênero Passiflora (Passifloraceae) é utilizado principalmente para tratar doenças do SNC e cardiovasculares. A espécie Passiflora nitida Kunth é comumente conhecida como \x93maracujá-do-mato". A literatura relata o consumo in natura dos frutos desta espécie pela população local para distúrbios gastrointestinais. Considerando o potencial farmacológico do gênero, este trabalho teve por objetivo realizar estudo de caracterização fitoquímica desta espécie e estudar os efeitos dos extratos aquoso (EA), etanólico (EE) e hexânico (EH) de suas folhas sobre a coagulação sanguínea e agregação plaquetária. Para a caracterização fitoquímica foram realizados testes de cromatografia em camada delgada e ressonância magnética nuclear. O efeito dos extratos sobre a coagulação foi avaliado pelos testes de tempo de protrombina (TP) e tempo de tromboplastina parcial ativada (TTPa). O efeito sobre a agregação plaquetária foi avaliado em plasma rico em plaquetas por método espectrofotométrico, usando adenosina difosfato (ADP) e adrenalina (ADR) como indutores da agregação. Os extratos EA, EE e EH apresentaram atividade coagulante pelo teste do TP e o EE apresentou atividade anticoagulante para o TTPa. Quando induzidos por ADP, os extratos EA, EE e EH apresentaram valores de concentração inibitória 50% (CI50, µg/mL) de 450,5 ± 50,7; 511,2 ± 35,5 e 394,4 ± 8,9, respectivamente, e quando induzidos por ADR apresentaram valores de 438,7 ± 5,2; 21,0 ± 1,9 e 546,9 ± 49,9, respectivamente. O EE apresentou atividade inibitória sobre a agregação. A caracterização fitoquímica foi sugestiva da presença de flavonóides e cumarinas, aos quais podem ser atribuídos, em parte, os efeitos biológicos estudados

Elemental concentration and sulfur chemical speciation in the amazonian plant andira surinamensis using synchrotron radiation techniques (SR-XRF, XANES), RBS and WD-XRF

The inorganic composition of the bark and leaf of a plant from the Amazon rainforest, Andira surinamensis, was determined using two non-destructive, multi-element techniques: X-ray fluorescence (XRF) and Rutherford backscattering spectrometry (RBS). XRF measurements were made using both a conventional X-ray source and synchrotron radiation. It was observed that although magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, and potassium are present in higher concentrations in the leaf, calcium is about three times more concentrated in the bark. Manganese, iron, copper, zinc, strontium and barium were also detected, with barium showing a concentration above the minimum toxicity level for plants. Chemical speciation of sulfur, performed using the X-ray absorption near edge structure (XANES) technique, showed that sulfur is present in several oxidation states, with a much larger contribution from the inorganic sulfate in the leaves. The article evidences that the combined use of synchrotron radiation and non-destructive multielement techniques allows for an efficient and accurate determination of the inorganic composition and chemical speciation in plants. © 2019 Sociedade Brasileira de Química

Estudo acerca da terapia intensiva em procedimentos neurológicos: sedação e analgesia específicas

Introdução. Ao longo dos anos a terapia intensiva vem sofrendo grandes alterações, sendo estas principalmente na área da tecnologia dos medicamentos usados diariamente em vários procedimentos. Essas mudanças podem proporcionar aos pacientes maior sobrevida. Porém, mesmo com tais avanços, o passo a passo da terapia intensiva associada a monitorização do paciente ainda trazem uma desagradável sensação ao mesmo, pois diariamente observamos pacientes que tentam a auto-extubação, retirada de cateter e assim por diante. A ansiedade é um aliado forte presente em grande parte desses pacientes, onde se faz muito necessário um controle especifico de cada paciente e se necessário, realizar medicamentos sedativos e analgésicos afim de tranquilizar tanto o paciente quanto a equipe que o cuida. Objetivo. Com este trabalho, buscamos analisar e compreender fatores que possam facilitar e melhorar a condição de vida dos pacientes que se encontram em terapia intensiva e que necessitam de sedativos e analgésicos para garantir maior segurança e conforto, afim de assegurar um melhor manejo e tratamento adequado para os mesmos, para que desta maneira estes tenham condições de vida mais satisfatórias que atualmente. Metodologia. A estratégia utilizada contou com estudos, tendo por base uma análise em plataformas como o Google Acadêmico, PubMed, SciELO, Medical Subject Heading (MeSH), nas quais cada fonte de dados contou com um estudo acerca dos títulos, assuntos e tipos específicos na língua portuguesa e inglesa. Resultados. Ficou evidenciado com o estudo que uma caracterização individual para cada paciente se faz necessário, onde analisar a melhor medicação para o momento, qual tipo de crise em que ele se encontra é tão importante que se realizado de forma correta irá assegurar conforto pleno a um paciente visivelmente instável pelo desconforto de uma UTI (Unidade de Terapia Intensiva). Um exemplo acerca deste fator é quanto aos analgésicos, devemos entender se o paciente está em uma síndrome álgica aguda, crônica, nociceptiva, neuropática ou mista e através desta avaliação caracterizar qual o melhor medicamento. Um outro exemplo, medicamentos benzodiazepínicos que atuam nos receptores GABA e possuem função sedativa e hipnótica devem ser escolhidos com muito cuidado, visto que esta droga irá promover um bloqueio das informações a partir daquele momento, logo, um cuidado minucioso é de grande importante, afim de não sedar um paciente sem necessidade. Conclusão. Os efeitos de uma sedação incorreta ainda não são tão evidentes, no entanto sabemos que que se isso ocorre, irá promover ao paciente o oposto que pensamos ao seda-lo, esse paciente poderá ter dor, desconforto, agitação, ansiedade e principalmente, alteração do esperado durante sua terapia. Sedativos em excesso só servem para interferir no atraso da recuperação do paciente, no aumento de tempo em que o mesmo ficara na UTI e ate mesmo uso prolongado de suporte de oxigênio, afim de assegurar maior conforto respiratório ao mesmo. Dessa forma fica muito claro que a sedação em pacientes críticos ou não, só se faz necessária após individualizar cada indivíduo e promover sedação e tratamento das causas fisiológicas do mesmo, afim de não ser surpreendido por qualquer problema de base do mesmo. Dessa forma, fica claro que os avanços se tornaram benéficos com os novos medicamentos, porém, tudo pode ser perdido quando não individualizamos cada paciente

Evolutionary Heritage Influences Amazon Tree Ecology

Lineages tend to retain ecological characteristics of their ancestors through time. However, for some traits, selection during evolutionary history may have also played a role in determining trait values. To address the relative importance of these processes requires large-scale quantification of traits and evolutionary relationships among species. The Amazonian tree flora comprises a high diversity of angiosperm lineages and species with widely differing life-history characteristics, providing an excellent system to investigate the combined influences of evolutionary heritage and selection in determining trait variation. We used trait data related to the major axes of life-history variation among tropical trees (e.g. growth and mortality rates) from 577 inventory plots in closed-canopy forest, mapped onto a phylogenetic hypothesis spanning more than 300 genera including all major angiosperm clades to test for evolutionary constraints on traits. We found significant phylogenetic signal (PS) for all traits, consistent with evolutionarily related genera having more similar characteristics than expected by chance. Although there is also evidence for repeated evolution of pioneer and shade tolerant life-history strategies within independent lineages, the existence of significant PS allows clearer predictions of the links between evolutionary diversity, ecosystem function and the response of tropical forests to global change

Measuring routine childhood vaccination coverage in 204 countries and territories, 1980-2019 : a systematic analysis for the Global Burden of Disease Study 2020, Release 1

Background Measuring routine childhood vaccination is crucial to inform global vaccine policies and programme implementation, and to track progress towards targets set by the Global Vaccine Action Plan (GVAP) and Immunization Agenda 2030. Robust estimates of routine vaccine coverage are needed to identify past successes and persistent vulnerabilities. Drawing from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2020, Release 1, we did a systematic analysis of global, regional, and national vaccine coverage trends using a statistical framework, by vaccine and over time. Methods For this analysis we collated 55 326 country-specific, cohort-specific, year-specific, vaccine-specific, and dosespecific observations of routine childhood vaccination coverage between 1980 and 2019. Using spatiotemporal Gaussian process regression, we produced location-specific and year-specific estimates of 11 routine childhood vaccine coverage indicators for 204 countries and territories from 1980 to 2019, adjusting for biases in countryreported data and reflecting reported stockouts and supply disruptions. We analysed global and regional trends in coverage and numbers of zero-dose children (defined as those who never received a diphtheria-tetanus-pertussis [DTP] vaccine dose), progress towards GVAP targets, and the relationship between vaccine coverage and sociodemographic development. Findings By 2019, global coverage of third-dose DTP (DTP3; 81.6% [95% uncertainty interval 80.4-82 .7]) more than doubled from levels estimated in 1980 (39.9% [37.5-42.1]), as did global coverage of the first-dose measles-containing vaccine (MCV1; from 38.5% [35.4-41.3] in 1980 to 83.6% [82.3-84.8] in 2019). Third- dose polio vaccine (Pol3) coverage also increased, from 42.6% (41.4-44.1) in 1980 to 79.8% (78.4-81.1) in 2019, and global coverage of newer vaccines increased rapidly between 2000 and 2019. The global number of zero-dose children fell by nearly 75% between 1980 and 2019, from 56.8 million (52.6-60. 9) to 14.5 million (13.4-15.9). However, over the past decade, global vaccine coverage broadly plateaued; 94 countries and territories recorded decreasing DTP3 coverage since 2010. Only 11 countries and territories were estimated to have reached the national GVAP target of at least 90% coverage for all assessed vaccines in 2019. Interpretation After achieving large gains in childhood vaccine coverage worldwide, in much of the world this progress was stalled or reversed from 2010 to 2019. These findings underscore the importance of revisiting routine immunisation strategies and programmatic approaches, recentring service delivery around equity and underserved populations. Strengthening vaccine data and monitoring systems is crucial to these pursuits, now and through to 2030, to ensure that all children have access to, and can benefit from, lifesaving vaccines.

Spatial, temporal, and demographic patterns in prevalence of chewing tobacco use in 204 countries and territories, 1990-2019 : a systematic analysis from the Global Burden of Disease Study 2019

Interpretation Chewing tobacco remains a substantial public health problem in several regions of the world, and predominantly in south Asia. We found little change in the prevalence of chewing tobacco use between 1990 and 2019, and that control efforts have had much larger effects on the prevalence of smoking tobacco use than on chewing tobacco use in some countries. Mitigating the health effects of chewing tobacco requires stronger regulations and policies that specifically target use of chewing tobacco, especially in countries with high prevalence. Findings In 2019, 273 center dot 9 million (95% uncertainty interval 258 center dot 5 to 290 center dot 9) people aged 15 years and older used chewing tobacco, and the global age-standardised prevalence of chewing tobacco use was 4 center dot 72% (4 center dot 46 to 5 center dot 01). 228 center dot 2 million (213 center dot 6 to 244 center dot 7; 83 center dot 29% [82 center dot 15 to 84 center dot 42]) chewing tobacco users lived in the south Asia region. Prevalence among young people aged 15-19 years was over 10% in seven locations in 2019. Although global agestandardised prevalence of smoking tobacco use decreased significantly between 1990 and 2019 (annualised rate of change: -1 center dot 21% [-1 center dot 26 to -1 center dot 16]), similar progress was not observed for chewing tobacco (0 center dot 46% [0 center dot 13 to 0 center dot 79]). Among the 12 highest prevalence countries (Bangladesh, Bhutan, Cambodia, India, Madagascar, Marshall Islands, Myanmar, Nepal, Pakistan, Palau, Sri Lanka, and Yemen), only Yemen had a significant decrease in the prevalence of chewing tobacco use, which was among males between 1990 and 2019 (-0 center dot 94% [-1 center dot 72 to -0 center dot 14]), compared with nine of 12 countries that had significant decreases in the prevalence of smoking tobacco. Among females, none of these 12 countries had significant decreases in prevalence of chewing tobacco use, whereas seven of 12 countries had a significant decrease in the prevalence of tobacco smoking use for the period. Summary Background Chewing tobacco and other types of smokeless tobacco use have had less attention from the global health community than smoked tobacco use. However, the practice is popular in many parts of the world and has been linked to several adverse health outcomes. Understanding trends in prevalence with age, over time, and by location and sex is important for policy setting and in relation to monitoring and assessing commitment to the WHO Framework Convention on Tobacco Control. Methods We estimated prevalence of chewing tobacco use as part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2019 using a modelling strategy that used information on multiple types of smokeless tobacco products. We generated a time series of prevalence of chewing tobacco use among individuals aged 15 years and older from 1990 to 2019 in 204 countries and territories, including age-sex specific estimates. We also compared these trends to those of smoked tobacco over the same time period. Findings In 2019, 273 & middot;9 million (95% uncertainty interval 258 & middot;5 to 290 & middot;9) people aged 15 years and older used chewing tobacco, and the global age-standardised prevalence of chewing tobacco use was 4 & middot;72% (4 & middot;46 to 5 & middot;01). 228 & middot;2 million (213 & middot;6 to 244 & middot;7; 83 & middot;29% [82 & middot;15 to 84 & middot;42]) chewing tobacco users lived in the south Asia region. Prevalence among young people aged 15-19 years was over 10% in seven locations in 2019. Although global age standardised prevalence of smoking tobacco use decreased significantly between 1990 and 2019 (annualised rate of change: -1 & middot;21% [-1 & middot;26 to -1 & middot;16]), similar progress was not observed for chewing tobacco (0 & middot;46% [0 & middot;13 to 0 & middot;79]). Among the 12 highest prevalence countries (Bangladesh, Bhutan, Cambodia, India, Madagascar, Marshall Islands, Myanmar, Nepal, Pakistan, Palau, Sri Lanka, and Yemen), only Yemen had a significant decrease in the prevalence of chewing tobacco use, which was among males between 1990 and 2019 (-0 & middot;94% [-1 & middot;72 to -0 & middot;14]), compared with nine of 12 countries that had significant decreases in the prevalence of smoking tobacco. Among females, none of these 12 countries had significant decreases in prevalence of chewing tobacco use, whereas seven of 12 countries had a significant decrease in the prevalence of tobacco smoking use for the period.

Multidifferential study of identified charged hadron distributions in ZZ-tagged jets in proton-proton collisions at s=\sqrt{s}=13 TeV

Jet fragmentation functions are measured for the first time in proton-proton collisions for charged pions, kaons, and protons within jets recoiling against a $Z$ boson. The charged-hadron distributions are studied longitudinally and transversely to the jet direction for jets with transverse momentum 20 $< p_{\textrm{T}} < 100$ GeV and in the pseudorapidity range $2.5 < \eta < 4$. The data sample was collected with the LHCb experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 1.64 fb$^{-1}$. Triple differential distributions as a function of the hadron longitudinal momentum fraction, hadron transverse momentum, and jet transverse momentum are also measured for the first time. This helps constrain transverse-momentum-dependent fragmentation functions. Differences in the shapes and magnitudes of the measured distributions for the different hadron species provide insights into the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-013.html (LHCb public pages
