A comparative assessment of air pollutants of smog in wagah border and other sites in Lahore, Pakistan / Uma avaliação comparativa de poluentes do ar do smog na fronteira de wagah e outros sites em Lahore, Paquistão

Abstract Smog has become the fifth season of Pakistan especially in Lahore city. Increased level of air pollutants (primary and secondary) are thought to be responsible for the formation of smog in Lahore. Therefore, the current study was carried out for the evaluation of air pollutants (primary and secondary) of smog in Wagah border particularly and other sites (Jail road, Gulburg) Lahore. For this purpose, baseline data on winter smog from March to December on primary and secondary air pollutants and meteorological parameters was collected from Environmental Protection Department and Pakistan Meteorological Department respectively. Devices being used in both departments for analysis of parameters were also studied. Collected data was further statistically analyzed to determine the correlation of parameters with meteorological conditions and was subjected to air quality index. According to results, PM 10 and PM 2.5 were found very high above the NEQS. NOx concentrations were also high above the permissible limits whereas SO2 and O3 were found below the NEQS thus have no roles in smog formation. Air Quality Index (AQI) of pollutants was PM 2.5(86-227), PM 10 (46-332), NOx (26-110), O3 (19-84) and SO2 (10-95). AQI of PM 2.5 remained between moderate to very unhealthy levels. AQI of PM 10 remained between good to hazardous levels. AQI of NOx remained between good to unhealthy for sensitive groups' levels. AQI of O3 and SO2 remained between good to moderate levels. Pearson correlation showed that every pollutant has a different relation with different or same parameters in different areas. It is concluded from the present study that particulate matter was much more responsible for smog formation. Although NOx also played role in smog formation. So there is need to reduce sources of particulate matter and NOx specifically in order to reduce smog formation in Lahore.

Resumo Smog tornou-se a quinta estação do Paquistão, especialmente na cidade de Lahore. Acredita-se que o aumento do nível de poluentes atmosféricos (primários e secundários) seja responsável pela formação de poluição atmosférica em Lahore. Portanto, o presente estudo foi realizado para a avaliação dos poluentes atmosféricos (primários e secundários) do smog na fronteira de Wagah em particular e em outros locais (Jail road, Gulburg) Lahore. Para este propósito, os dados de referência sobre a poluição atmosférica de inverno de março a dezembro sobre poluentes atmosféricos primários e secundários e parâmetros meteorológicos foram coletados do Departamento de Proteção Ambiental e do Departamento Meteorológico do Paquistão, respectivamente. Dispositivos sendo usados ​​em ambos os departamentos para análise de parâmetros também foram estudados. Os dados coletados foram posteriormente analisados ​​estatisticamente para determinar a correlação dos parâmetros com as condições meteorológicas e foram submetidos ao índice de qualidade do ar. De acordo com os resultados, PM 10 e PM 2,5 foram encontrados muito acima do NEQS. As concentrações de NOx também estavam muito acima dos limites permitidos, enquanto SO2 e O3 foram encontrados abaixo do NEQS, portanto, não têm papéis na formação de smog. O índice de qualidade do ar (AQI) de poluentes foi PM 2,5 (86-227), PM 10 (46-332), NOx (26-110), O3 (19-84) e SO2 (10-95). O AQI de PM 2,5 permaneceu entre níveis moderados a muito prejudiciais à saúde. O AQI de PM 10 permaneceu entre níveis bons e perigosos. AQI de NOx permaneceu entre bom e não saudável para os níveis de grupos sensíveis. O AQI de O3 e SO2 permaneceu entre níveis bons a moderados. A correlação de Pearson mostrou que cada poluente tem uma relação diferente com parâmetros diferentes ou iguais em áreas diferentes. Conclui-se do presente estudo que o material particulado foi muito mais responsável pela formação de smog. Embora o NOx também tenha desempenhado um papel na formação do smog. Portanto, é necessário reduzir as fontes de partículas e NOx, especificamente para reduzir a formação de smog em Lahore.

Association of blood groups/Rh and diabetes mellitus in Karachi city, Pakistan / Associação de grupos sanguíneos/Rh e diabetes mellitus na cidade de Karchi, Paquistão

Abstract The main purpose of this study was to find out a possible association between ABO blood groups or Rh and diabetes mellitus (DM) in the local population of eight (8) different towns of Karachi, Pakistan. For this purpose a survey was carried out in Karachi to have a practical observation of these towns during the period of 9 months from June 2019 to Feb. 2020. Out of eighteen (18) towns of Karachi, samples (N= 584) were collected from only eight (8) Towns of Karachi and gave a code-number to each town. Diabetic group sample was (n1=432) & pre-diabetes sample was (n2 =152). A standard Abbot Company Glucometer for Random Blood Sugar (RBS) and Fasting Blood Sugar (FBS) tests, standard blood anti sera were used for ABO/Rh blood type. Health assessment techniques were performed ethically by taking informed consent from all registered subjects. Finally data was analyzed by SPSS version 20.0. In our current study, the comparison of ABO blood groups frequencies between diabetic and pre-diabetic individuals were carried out. The percentage values of blood Group-B as given as: (32% in DM vs. 31% in pre-diabetics), followed by blood Group-O as: (18% in DM vs. 11% in pre-diabetics). Contrary to Group-"B" & "O", blood Group-A and Group-AB were distribution percentage higher pre-diabetic as compared to DM patients, as given as: Group-A (32% in pre-diabetics vs. 26% in DM) & Group-AB (26% in pre-diabetics vs. 24% in diabetic's patients). In addition, percentage distribution of Rh system was also calculated, in which Rh+ve Group was high and more common in DM patients as compared to pre-diabetics; numerically given as: Rh+ve Group (80% in DM vs. 72% in pre-diabetics). Different views and dimensions of the research topic were studied through literature support, some have found no any association and some established a positive association still some were not clear in making a solid conclusion. It is concluded that DM has a positive correlation with ABO blood groups, and people with Group-B have increased susceptibility to DM disease.

Resumo O objetivo principal deste estudo foi descobrir uma possível associação entre grupos sanguíneos ABO ou Rh e diabetes mellitus (DM) na população local de oito (8) diferentes cidades de Karachi, Paquistão. Para tanto, foi realizado um levantamento em Karachi para observação prática dessas cidades durante o período de 9 meses de junho de 2019 a fevereiro de 2020.De dezoito (18) cidades de Karachi, as amostras (N = 584) foram coletadas de apenas oito (8) cidades de Karachi e deram um número-código para cada cidade. A amostra do grupo de diabéticos foi (n1 = 432) e a amostra de pré-diabetes foi (n2 = 152). Um glicômetro padrão da Abbot Company para testes de açúcar no sangue aleatório (RBS) e açúcar no sangue em jejum (FBS), antissoros de sangue padrão foram usados ​​para o tipo de sangue ABO / Rh. As técnicas de avaliação de saúde foram realizadas de forma ética, tomando o consentimento informado de todos os indivíduos registrados. Finalmente, os dados foram analisados ​​pelo SPSS versão 20.0.No presente estudo, foi realizada a comparação das frequências dos grupos sanguíneos ABO entre diabéticos e pré-diabéticos. Os valores percentuais do sangue do Grupo-B são dados como: (32% em DM vs. 31% em pré-diabéticos), seguido pelo sangue do Grupo-O como: (18% em DM vs. 11% em pré-diabéticos). Ao contrário dos Grupos "B" e "O", sangue do Grupo-A e Grupo-AB tiveram distribuição percentual maior de pré-diabéticos em comparação com pacientes com DM, dado como: Grupo-A (32% em pré-diabéticos vs. 26% em DM) e Grupo AB (26% em pré-diabéticos vs. 24% em pacientes diabéticos). Além disso, também foi calculada a distribuição percentual do sistema Rh, no qual o Grupo Rh + ve foi elevado e mais comum em pacientes com DM em comparação aos pré-diabéticos; dados numericamente como: Grupo Rh + ve (80% em DM vs. 72% em pré-diabéticos). Diferentes visões e dimensões do tema de pesquisa foram estudadas com o suporte da literatura, alguns não encontraram nenhuma associação e alguns estabeleceram uma associação positiva, embora alguns não estivessem claros em fazer uma conclusão sólida. Conclui-se que o DM tem correlação positiva com os grupos sanguíneos ABO, e as pessoas com o Grupo B têm maior suscetibilidade à doença DM.

Association between temperature and mortality: a multi-city time series study in Sichuan Basin, southwest China

BACKGROUND@#There are few multi-city studies on the association between temperature and mortality in basin climates. This study was based on the Sichuan Basin in southwest China to assess the association of basin temperature with non-accidental mortality in the population and with the temperature-related mortality burden.@*METHODS@#Daily mortality data, meteorological and air pollution data were collected for four cities in the Sichuan Basin of southwest China. We used a two-stage time-series analysis to quantify the association between temperature and non-accidental mortality in each city, and a multivariate meta-analysis was performed to obtain the overall cumulative risk. The attributable fractions (AFs) were calculated to access the mortality burden attributable to non-optimal temperature. Additionally, we performed a stratified analyses by gender, age group, education level, and marital status.@*RESULTS@#A total of 751,930 non-accidental deaths were collected in our study. Overall, 10.16% of non-accidental deaths could be attributed to non-optimal temperatures. A majority of temperature-related non-accidental deaths were caused by low temperature, accounting for 9.10% (95% eCI: 5.50%, 12.19%), and heat effects accounted for only 1.06% (95% eCI: 0.76%, 1.33%). The mortality burden attributable to non-optimal temperatures was higher among those under 65 years old, females, those with a low education level, and those with an alternative marriage status.@*CONCLUSIONS@#Our study suggested that a significant association between non-optimal temperature and non-accidental mortality. Those under 65 years old, females, and those with a low educational level or alternative marriage status had the highest attributable burden.

Una plaga citadina peligrosa: los murciélagos / A dangerous urban pest: bats

Los murciélagos son mamíferos vertebrados presentes en la Ciudad de Buenos Aires, estimándose una población de 4 animales por habitante. Son portadores de varias enfermedades importantes y además empeoran las condiciones respiratorias de enfermos crónicos. En el campo cumplen una interesante función, ya que se alimentan de insectos perjudiciales para las siembras. El guano puede ser útil en el abono de la tierra debido al aporte de carbono y nitrógeno. En las ciudades su presencia tiene consecuencias diferentes. Se encuentran en los taparrollos de las habitaciones, así como también en todas las oquedades de muros, árboles, grietas, etc. Se exponen aquí los peligros y los cuidados que deben tenerse en la Ciudad de Buenos Aires ante la invasión de estos quirópteros. (AU)

Bats are vertebrate mammals present in the City of Buenos Aires, with an estimated population of 4 animals per inhabitant. They are carriers of several important diseases and also worsen the respiratory conditions of the chronically ill. In rural areas they fulfill an interesting function, since they feed on insects harmful to crops. Guano can be useful in soil fertilization due to its contribution of carbon and nitrogen. In cities their presence has different consequences. They are found in the roll covers of the rooms as well as in all the hollows of walls, trees, cracks, etc. The dangers and precautions to be taken in the city of Buenos Aires in the face of the invasion of these chiroptera are described here.

Introduction. The neonatal mortality rate (NMR) is an indicator of socioeconomic, environmental, andhealth care conditions. The Matanza-Riachuelo River Basin (MRRB) is the most polluted in Argentina.Objective. To analyze neonatal mortality (NM) in the MRRB between 2010 and 2019 and compare itwith overall data for Argentina, the province of Buenos Aires (PBA), and the City of Buenos Aires (CABA)in 2019.Population and methods. Descriptive study based on vital statistics provided by the Ministry of Health. Results. In 2019, the NMR was 6.4‰ in the MRRB, 6.2‰ in Argentina; 6‰ in PBA; and 5.1‰ in CABA.The risk of NM in the MRRB was higher than in CABA (RR: 1.32, 95% CI: 1.08­1.61). Between 2010and 2019, the NMR decreased in the MRRB, PBA, and Argentina; but not in CABA.The risk of NM due to perinatal conditions in the MRRB was higher than in CABA (RR: 1.30, 95%CI: 1.01­1.67).The risk of death among very low birth weight (VLBW) live births (LBs) in the MRRB was higher than in CABA(RR: 1.70, 95% CI: 1.33­2.18) and lower than in Argentina (RR: 0.78, 95% CI: 0.70­0.87).Conclusion. The evolution of NMR between 2010 and 2019 was similar in the MRRB, Argentina, andPBA. In 2019, the structure of causes and the risk of NM were similar in the MRRB, PBA, and Argentina,with a higher risk due to perinatal conditions and among VLBW LBs. The NMR among VLBW LBs waslower in the MRRB than in Argentina

Transferências intergovernamentais são capturadas pelos servidores municipais? Os determinantes da diferença salarial entre o setor público e o setor privado / ¿Las transferencias intergubernamentales son captadas por servidores municipales? Los determinantes de la brecha salarial entre los sectores público y privado / Do local civil servants capture intergovernmental transfers? The different wage determinants between the public and private sector

Resumo Esta pesquisa tem por objetivo investigar o efeito das transferências intergovernamentais na diferença salarial entre os servidores municipais e os funcionários do setor privado. A amostra foi formada por 5.449 municípios durante o período de 2000 a 2016, agrupados em 5.344 áreas mínimas comparáveis. Os procedimentos metodológicos quantitativos foram desenvolvidos em duas etapas. Na primeira, mediu-se a diferença salarial mediana entre os servidores municipais e os funcionários do setor privado por meio da regressão quantílica incondicional. Na segunda, a análise dos determinantes da diferença salarial foi realizada por meio de regressão múltipla com dados em painel, efeitos fixos e estimações adicionais com erros robustos a cluster, correlação temporal e correlação espacial. Os resultados indicaram que o aumento de 1% das transferências intergovernamentais per capita resulta em aumento de 0,067% na diferença salarial nos municípios brasileiros entre os servidores municipais e os funcionários do setor privado. Além disso, a elevação de 1% no Produto Interno Bruto (PIB) per capita resulta numa redução de 0,036% da diferença salarial. Por último, a pesquisa observou que o tamanho populacional aumenta enquanto a competição eleitoral reduz a diferença salarial nos municípios brasileiros.

Resumen Esta investigación tuvo como objetivo investigar el efecto de las transferencias intergubernamentales en la diferencia salarial entre los servidores municipales y los empleados del sector privado. La muestra estuvo conformada por 5.449 municipios durante el período 2000 a 2016, agrupados en 5.344 áreas mínimas comparables. Los procedimientos metodológicos cuantitativos se desarrollaron en dos etapas. En la primera, la mediana de la diferencia salarial entre los empleados municipales y los del sector privado se midió utilizando la regresión por cuantiles incondicionales. En la segunda etapa, el análisis de los determinantes de la brecha salarial se realizó mediante regresión múltiple con datos de panel, efectos fijos y estimaciones adicionales con errores robustos por clúster, correlación temporal y correlación espacial. Los resultados indicaron que un aumento del 1% en las transferencias intergubernamentales per cápita resulta en un aumento del 0,067% en la brecha salarial en los municipios brasileños entre los servidores municipales y los empleados del sector privado. Además, identificó que un aumento de 1% en el PIB per cápita se traduce en una reducción de 0,036% en la brecha salarial. Finalmente, la investigación observó que el tamaño de la población aumenta mientras la competencia electoral reduce la brecha salarial en los municipios brasileños.

Abstract This article examines the intergovernmental transfer effects on wage differences between local civil servants and private sector employees. The sample was composed of 5,449 Brazilian municipalities, working with data from 2000 to 2016 clustered in 5,344 minimum comparable areas (MCA). The methodological procedures were quantitative and developed in two steps. The first step was to assess the median wage difference between local civil servants and private sector employees through unconditional quantile regression. The second was the analysis of different wage determinants through multiple regression with panel data, fixed effects, and additional estimations such as cluster-robust standard errors, temporal correlation, and spatial correlation. The results demonstrated that when per capita intergovernmental transfers increase by 1%, the wage difference between local civil servants and private sector employees increases by 0.067%. Besides that, when per capita GDP increases by 1%, the wage difference decreases by 0.036%. Furthermore, the paper observed that populational size increases and electoral competition decreases wage differences between the public and private sectors in Brazilian municipalities.

Desigualdades territoriales de la tuberculosis entre los municipios de La Habana, 2015 y 2016-2020 / Territorial Inequalities of Tuberculosis between the Municipalities of Havana, 2015 and 2016-2020

La Habana notifica el 30% de casos de tuberculosis (TB) en Cuba. Objetivo: valorar las desigualdades territoriales en la ocurrencia de TB en los municipios de La Habana, 2015 y 2016-2020 según algunos determinantes intermedios e individuales. Métodos: estudio ecológico de series temporales sobre las notificaciones de TB en 2015 y 2016-2020. La fuente fue la base de vigilancia del MINSAP. Calculamos la tasa del periodo (TP), la referencia fue la menor, estimamos las diferencias absolutas y relativas, y el Riesgo Atribuible Poblacional Porcentual. Estimamos la TP en menores y mayores de 19 años. Según la TP, propusimos dos escenarios: -reducción 5% anual a todos los municipios, según Hitos de OMS y -reducción discriminada 5% anual a municipios con TP < 9 y 7% los ≥ 9/100.000. Calculamos dos índices de dispersión y proporciones de TB en VIH y reclusos. Categorizamos los municipios según metas renovadas hacia la eliminación. Resultados: el municipio de referencia fue Playa (5,5), la diferencia relativa fue 3,3 veces más en Habana Vieja. Cotorro y Guanabacoa no aportaron casos pediátricos. El segundo escenario tuvo desigualdad moderada. Predominaron los TB-VIH, en Habana Vieja (13,1%). 11/15 municipios categorizaron en control satisfactorio. Conclusiones: las desigualdades en general son moderadas en los municipios Habana, no obstante, las tasas de TB infantil son muy bajas en los territorios, dos de ellos alcanzaron la meta de eliminación. La coinfección TB/VIH concentra las mayores proporciones en algunos municipios. (AU);

Havana notifies 30% of cases of tuberculosis (TB) in Cuba. Objective: to assess the territorial inequalities in the occurrence of TB in the municipalities of Havana, 2015 and 2016-2020 according to some intermediate and individual determinants. Methods: ecological study of time series on TB notifications in 2015 and 2016-2020. The source was the MINSAP surveillance base. We calculated the period rate (TP), the reference was the lowest, we estimated the absolute and relative differences, and the Percentage Population Attributable Risk. We estimate the PT in children under and over 19 years of age. According to the TP, we proposed two scenarios: -5% annual reduction to all municipalities, according to WHO Milestones and -discriminated 5% annual reduction to municipalities with TP < 9 and 7% those ≥ 9/100,000. We calculated two dispersion indices and proportions of TB in HIV and inmates. We categorized the municipalities according to renewed goals towards elimination. Results: the reference municipality was Playa (5.5), the relative difference was 3.3 times more in Habana Vieja. Cotorro and Guanabacoa did not provide pediatric cases. The second scenario had moderate inequality. TB-HIV predominated in Old Havana (13.1%). 11/15 municipalities categorized in satisfactory control. Conclusions: inequalities were generally moderate in the Havana municipalities, however, the rates of childhood TB are very low in the territories, two of them reached the elimination goal. TB/HIV coinfection concentrates the highest proportions in some municipalities. (AU)

Policy-making ou recompensas? Nomeações políticas nos governos municipais brasileiros / ¿Hacer políticas o recompensas? Nombramientos políticos en los gobiernos municipales brasileños / Policy-making or rewards: political appointments in Brazilian municipal governments

Resumo O Brasil possui 5.570 municípios e em cada um deles governos eleitos dispõem de um estoque de cargos em comissão disponíveis para nomeação discricionária. É possível observar variações nas estratégias políticas adotadas para essas indicações? Os principais achados deste trabalho permitidos através do uso de estatística descritiva e inferencial foram (1) identificação de diferentes estratégias de nomeação política entre recompensa (escopo elevado/escolaridade baixa) e policy-making (escopo reduzido/escolaridade alta) (2) robusta relação entre IDH e nomeações políticas com perfil de policy-making inferindo menores custos de coordenação e assimetrias informacionais para principais/eleitores e, (3) variáveis partidárias e de competição eleitoral apresentaram resultados modestos como candidatas a explicar a adoção de estratégias de recompensa, da mesma forma que estratégias de recompensa - maior proporção de CCs e menor escolaridade destes - não afetaram as razões de chance de incumbentes nas eleições municipais seguintes.

Resumen Brasil tiene 5.570 municipios y en cada uno de ellos los gobiernos elegidos electos tienen un stock de puestos en comisión disponibles para su nombramiento discrecional. ¿Es posible observar variaciones en las estrategias políticas adoptadas para estas candidaturas? Los principales hallazgos de este trabajo obtenidos mediante el uso de estadísticas descriptivas e inferenciales fueron (1) identificación de diferentes estrategias de nombramiento político entre recompensa (alcance alto/educación baja) y formulación de políticas (alcance reducido/educación alta); (2) relación sólida entre el IDH y los nombramientos políticos con un perfil de hacedor de políticas que infiere menores costos de coordinación y asimetrías de información para los principales/votantes y, (3) las variables de competencia electoral y partidaria mostraron resultados modestos como candidatas para explicar la adopción de estrategias de recompensa, de la misma manera que las estrategias de recompensa -mayor proporción de CC y menor escolaridad de estos- no afectaron las razones de probabilidad de los titulares en las siguientes elecciones municipales.

Abstract Brazil has 5,570 municipalities, and each local government has a stock of appointed positions. This study adopted descriptive and inferential statistics to observe the variations in the political strategies adopted when filling these positions. The research identified (1) different political appointment strategies, from those based on reward (high scope/low education level) to strategies based on policy-making (reduced scope/high education level), (2) a robust relationship between HDI and political appointments with a policy-making profile inferring lower coordination costs and informational asymmetries for principals/voters, and (3) party and electoral competition variables showed modest results as potential explanatory factors to adopting reward-based strategies. Also, the adoption of reward-based strategies - cases where municipalities' employees presented a higher proportion of appointees with lower education levels - did not affect the odds ratios of incumbents in the next municipal elections.

Narcisismo e biopolítica: por uma sustentabilidade afetiva em tempos sombrios / NARCISISM and biopolitical: for an affective sustainability in gloomy times / NARCISISMO y biopolítica: por la sostenibilidad afectiva en tiempos oscuros

Estudos acerca dos riscos socioambientais são frequentes. Diante deles, cientistas alertam que, caso não sejam tomadas providências, é a própria vida no planeta que estará em perigo. Esta pesquisa objetivou identificar e analisar, sob o enfoque da Psicologia Social e da Filosofia da Diferença, experiências de sustentabilidade afetiva no espaço urbano diante da emergência da pandemia. Adotando a estratégia metodológica da história oral, buscou-se acompanhar o relato de participantes vinculados a uma Instituição de Ensino Superior que se dispuseram a compartilhar os impactos afetivos da relação com a cidade em estado pandêmico. Os relatos foram analiticamente organizados em dois eixos: 1. Desterritorializações e medos; 2. Frustrações narcísicas e restrições biopolíticas. Os resultados mostraram que as percepções iniciais diante do contato com a pandemia foram marcadas por afetos de surpresa, angústia e medo. Concluiu-se que sustentar afetivamente esta experiência comportou desafios relacionais colocados à coletividade em sua interface com as cidades.

Studies on the socio-environmental risks are frequents. Scientists warn that if no immediate action is taken, it is life itself on the planet that will be in danger. This research aimed to identify and analyze, under the focus of Social Psychology and the Philosophy of Difference, experiences of affective sustainability in the urban space. Adopting a methodology strategy of oral history, we sought to follow the reports of participants linked a Superior Institution of Studies who were willing to share the affective impacts resulting from your urban relation in pandemic station. The reports were analytically organized in two axes: 1. Deterritorialization and fears; 2. Narcissistic frustrations and biopolitical restrictions. The results show that the first perceptions were marked by surprise, anguish and fear. It concluded that affectively sustaining this experience is still a challenge posed for collectivity in its interface with the cities.

Son frecuentes los estudios sobre los riesgos socio ambientales. Ante ellos, científicos advierten que, si no se toman medidas inmediatas, es la vida del planeta la que estará en peligro.

Diversity of fungi obtained from bats captured in urban forest fragments in Sinop, Mato Grosso, Brazil / Diversidade de fungos em morcegos de fragmentos florestais urbanos de Sinop, Mato Grosso, Brasil

Abstract Bats are important for the homeostasis of ecosystems and serve as hosts of various microorganisms including bacteria, viruses, and fungi with pathogenic potential. This study aimed to isolate fungi from biological samples obtained from bats captured in the city of Sinop (state of Mato Grosso, Brazil), where large areas of deforestation exist due to urbanization and agriculture. On the basis of the flow of people and domestic animals, 48 bats were captured in eleven urban forest fragments. The samples were processed and submitted to microbiological cultures, to isolate and to identify the fungal genera. Thirty-four (70.83%) of the captured bats were positive for fungi; 18 (37.5%) and 16 (33.33%) of these bats were female and male, respectively. Penicillium sp., Scopulariopsis sp., Fusarium sp., Aspergillus sp., Alternaria sp., Cryptococcus sp., Trichosporon sp., and Candida sp., which may cause opportunistic infections, were isolated. The bat species with the highest number of fungal isolates was Molossus molossus: 21 isolates (43.8%). According to our results, bats captured in urban forest fragments in Sinop harbor pathogenic fungi, increasing the risk of opportunistic fungal infections in humans and domestic animals.

Resumo Os morcegos apresentam grande importância na homeostasia dos ecossistemas e são hospedeiros de uma rica diversidade de micro-organismos como bactérias, vírus e fungos com potencial patogênico. Portanto, este estudo visou isolar fungos presentes em amostras biológicas de morcegos na cidade de Sinop - MT, que possui grandes áreas de desmatamento devido à urbanização e agricultura. Foram capturados 48 morcegos de diferentes espécies, em onze fragmentos florestais urbanos definidos de acordo com fluxo de pessoas e animais domésticos, para obtenção de amostras biológicas. Essas amostras foram processadas e submetidas aos cultivos microbiológicos, para isolamento e identificação dos gêneros dos fungos. Dos 48 morcegos, 34 (70,83%) foram positivos para pelos menos um gênero de fungo, sendo 18 (37,5%) fêmeas e 16 (33,33%) machos, e os gêneros isolados a partir das amostras biológicas foram Penicillium sp., Scopulariopsis sp., Fusarium sp., Aspergillus sp., Alternaria sp., Cryptococcus sp., Trichosporon sp. e Candida sp., que podem ser causadores de infecções oportunistas. Desse total, a espécie que apresentou maior positividade para pelo menos um gênero de fungo foi Molossus molossus com 21 (43,8%). Nossos resultados demonstram que os morcegos capturados nos fragmentos florestais urbanos na cidade de Sinop - MT, podem atuar como agentes veiculadores de fungos com potencial patogênico, aumentando assim o risco de exposição e aquisição de infecções fúngicas oportunistas por pessoas e animais domésticos.

Study of human knowledge and attitude toward urban birds in Faisalabad city, Pakistan / Estudo do conhecimento humano e da atitude em relação às aves urbanas na cidade de Faisalabad, Paquistão

Abstract Birds are very valuable indicators of species richness and endemic patterns in a specified ecosystem, which eventually help the scientist to measure the environmental degradation. The aim of present study was to know human knowledge and attitude toward urban birds in Faisalabad city, Pakistan. The study conducted in four consecutive months: November 2019 to February 2020. Population of birds was noted from eight residential towns of Faisalabad city, data were collected through questionnaire. Faisalabad has a reasonably large population of birds and present data show that, there is a significant difference between favorite bird of residential areas and institutions. The pigeon received the most likeness in bird population among residential area residents, while the myna received the least. The most popular bird in Faisalabad institutions was the sparrow, while the least popular bird was the common myna. Bird adaptation percentage of residential areas and institutional areas of Faisalabad was the highest for parrot and sparrow respectively. People in residential areas and institutions, on the other hand, adapted least to common myna.

Objective: To explore the present situation and epidemiological characteristics of pesticide poisoning in Chengdu City from 2012 to 2021, and to provide scientific evidence for further prevention and control. Methods: In January 2022, the pesticide poisoning report cards of Chengdu City from 2012 to 2021 were collected from the China Disease Control and Prevention Information System. The data of the report card was reorganized and the distribution characteristics of pesticide poisoning such as time, region, gender, age and pesticide types were analyzed. Results: 14326 cases of pesticide poisoning were reported in Chengdu City from 2012 to 2021, 651 deaths, and the fatality rate was 4.54%. The cases of productive pesticide poisoning and unproductive pesticide poisoning were 504 and 13822, respectively. The fatality rates of productive and unproductive pesticide poisoning were 1.39% and 4.66%, which were significant different (χ(2)=11.99, P=0.001). The highest reported cases of pesticide poisoning was in 2013 (1779) and the lowest in 2021 (1047). The number of reported cases showed a downward trend year by year (t=-12.30, P<0.001), and the fatality rates also showed a downward trend year by year (χ(2)(trend)=25.48, P<0.001). The fluctuation range of unproductive pesticide poisoning cases in each month of the year was small, and the productive pesticide poisoning mainly occurred from May to August. The regions with the largest number of reported poisoning cases were Pengzhou (1620), Jianyang (1393), Jintang (1266) and Qionglai (1158). The high incidence of poisoning was among 25-54 years old (50.21%, 7193/14326). The fatality rate in the age group 75-96 years old was the highest (8.98%, 95/1058), and the fatality rates increased gradually with age (χ(2)(trend)=186.03, P<0.001). The pesticides causing poisoning were mainly insecticide (43.86%, 6284/14326) and herbicides (35.75%, 5121/14326). Herbicides paraquat had the highest fatality rate (9.54%, 286/2998) . Conclusion: Pesticide poisoning in Chengdu City is mainly unproductive poisoning. Health education should be carried out for key areas and people, and the control of highly toxic pesticides such as insecticide and herbicides should be strengthened.

Status and associated factors of pre-exposure prophylaxis use among men who have sex with men in 24 cities in China / 中华流行病学杂志

Objective: To understand the cognition and medication use of pre-exposure prophylaxis (PrEP) among men who have sex with men (MSM) in China and its associated factors. Method: From August 25 to September 5, 2021, 2 447 MSM were recruited in 24 cities to complete the online questionnaire through a male social interaction platform, Blued 7.5 software. The survey contents included demographic information of the respondents, PrEP awareness and usage, and risk behaviors. Descriptive analysis and multi-level logistic regression were performed for data analysis. SPSS 24.0 and SAS 9.4 software were used for statistical analysis. Results: Among the 2 447 respondents of MSM, 1 712 (69.96%) had heard of PrEP, 437 (17.86%) ever used PrEP, 274 (11.20%) were on PrEP, and 163 (6.66%) had discontinued PrEP; among the 437 cases (whoever used PrEP), more than 61.88% (388/627) adopted emtricitabine/tenofovir disoproxil fumarate regimen, and most of them adopted on-demand regimen. The average PrEP dosage reported in the past year is 1.12 tabletsper person per week. PrEP purchase was primarily via an online channel, and the most concerned factor was the PrEP effectiveness on HIV prevention. The most common reasons for discontinuing PrEP, reported by 163 cases, were the lack of HIV risk perception, the use of a condom to prevent HIV, and the economic burden of PrEP use. The logistic regression analysis showed that PrEP use among MSM in 24 cities was statistically associated with age, monthly income, ever having unprotected anal sex in the past year, used sexual drugs and sexually transmitted disease (STD) diagnosis in the past year. Compared with MSM aged 18-24, the proportion of MSM was relatively lower among those aged 25-44, who discontinued the PrEP (aOR=0.54,95%CI:0.34-0.87) or never used PrEP (aOR=0.62,95%CI:0.44-0.87). The proportion of unprotected anal sex among MSM currently on PrEP use was higher than those who have stopped PrEP and never used PrEP (all P<0.05). Those MSM group, with monthly income higher than 5 000 Yuan, used sexual drugs and STD diagnosis in the past year were more likely to have a higher rate for PrEP usage (all P<0.05). Conclusions: Currently, pre-exposure prophylaxis in the MSM group is primarily obtained via the online channel and adopted in an on-demand mode. Although the PrEP users have reached a certain proportion, it is still necessary to strengthen health education on the PrEP effects and side effects of MSM and to improve the awareness and use rate, especially for young MSM group, which can be combined with the advantages of the internet targeting its needs and use barriers.

Objective: To understand the influence of meteorological factors on the morbidity of influenza in northern cities of China and explore the differences in the influence of meteorological factors on the morbidity of influenza in 15 cities. Methods: The monthly reported morbidity of influenza and monthly meteorological data from 2008 to 2020 were collected in 15 provincial capital cities, including Xi 'an, Lanzhou, Xining, Yinchuan and Urumqi (5 northwestern cities), Beijing, Tianjin, Shijiazhuang, Taiyuan, Hohhot, Ji'nan, Zhengzhou (7 northern cities), Shenyang, Changchun and Harbin (3 northeastern cities). The panel data regression model was applied to conduct quantitative analyze on the influence of meteorological factors on influenza morbidity. Results: The univariate and multivariate panel regression analysis showed that after controlling the population density and other meteorological factors, for each 5 ℃ drop of monthly average temperature, the morbidity change percentage (MCP) of influenza was 11.35%, 34.04% and 25.04% in the 3 northeastern cities, 7 northern cities and 5 northwestern cities, respectively, and the best lag period months was 1, 0 and 1 month; When the monthly average relative humidity decreased by 10%, the MCP was 15.84% in 3 cities in northeastern China and 14.80% in 7 cities in northern China respectively, and the best lag period months was 2 and 1 months respectively; The MCP of 5 cities in northwestern China was 4.50% for each 10 mm reduction of monthly accumulated precipitation, and the best lag period months was 1 month; The MCPs of 3 cities in northeastern China and 5 cities in northwestern China were 4.19% and 5.97% respectively when the accumulated sunshine duration of each month decreased by 10 hours, the best lag period months was 1 month. Conclusions: In northern cities of China from 2008 to 2020, the temperature, relative humidity, precipitation and sunshine duration all had negatively impact on the morbidity of influenza, and temperature and relative humidity were the main sensitive meteorological factors. Temperature had a strong direct impact on the morbidity of influenza in 7 cities in northern China, and relative humidity had a strong lag effect on the morbidity of influenza in 3 cities in northeastern China. The duration of sunshine in 5 cities in northwestern China had a greater impact on the morbidity of influenza compared with 3 cities in northeastern China.

Drug resistance and genomic characteristics of Salmonella enterica serovar London from clinical and food sources in Hangzhou City from 2017 to 2021 / 中华预防医学杂志

Objective: To analyze the drug resistance and genomic characteristics of Salmonella enterica serovar London isolated from clinical and food sources in Hangzhou City from 2017 to 2021. Methods: A total of 91 Salmonella enterica serovar London strains isolated from Hangzhou City from 2017 to 2021 were analyzed for drug susceptibility, pulsed field gel electrophoresis (PFGE) typing and whole genome sequencing. Multilocus sequence typing (MLST), core genome multilocus sequence typing (cgMLST) and detection of drug resistance genes were performed by using the sequencing data. Phylogenetic analysis was conducted to compare the 91 genomes from Hangzhou City with 347 genomes from public databases. Results: No significant difference in the drug resistance rate was observed between clinical strains and food strains to 18 drugs in Hangzhou City(all P>0.05), and the multidrug resistance (MDR) rate was 75.8% (69/91). Most strains were resistant to 7 drug classes simultaneously. One strain was resistant to Polymyxin E as well as positive for mcr-1.1, and 50.5% (46/91) of the strains were resistant to Azithromycin and were positive for mph(A). All 91 Salmonella enterica serovar London strains were ST155, which were subdivided into 44 molecular types by PFGE and 82 types by cgMLST. Phylogenetic analysis showed that most strains from Hangzhou City (83/91) were clustered together, and a small number of human isolates from Europe, North America and pork isolates from Hubei and Shenzhen were mixed in the cluster. Other strains from Hangzhou City (8/91) were closely related to strains from Europe, America and Southeast Asia. Strains isolated from pork were the most closely related to clinical strains. Conclusion: The epidemic of Salmonella enterica serovar London in Hangzhou City is mainly caused by the spread of ST155 strains, which is mainly transmitted locally. At the same time, cross-region transmission to Europe, North America, Southeast Asia, and other provinces and cities in China may also occur. There is no significant difference in the drug resistance rate between clinical strains and food strains, and a high level of MDR is found in the strains. Clinical infection of Salmonella enterica serovar London may be closely related to pork consumption in Hangzhou City.

Difusão da Lei Geral da Micro e Pequena Empresa em municípios paulistas / Difusión de la Ley General de las Micro y Pequeñas Empresas en los municipios de São Paulo / Diffusion of the Micro and Small Business Law in municipalities of São Paulo

Resumo Este artigo tem como objeto de análise a implantação da Lei Complementar nº 123, de 2006 (LC nº 123/2006), que instituiu o Estatuto Nacional da Microempresa e da Empresa de Pequeno Porte (MPE), por municípios paulistas. Utilizou-se o referencial teórico de difusão de políticas públicas tendo como objetivo estudar seu processo de adoção, observando os diferentes contextos e momentos de coerção previstos na legislação federal. Com base nas discussões teóricas relacionadas com o mecanismo de difusão chamado de coerção, respondeu-se a seguinte pergunta: qual é a influência do mecanismo de coerção vertical na difusão da Lei Geral da MPE nos municípios paulistas? A técnica "análise de sobrevivência" foi aplicada para identificar fatores explicativos da difusão da política, considerando variáveis de desenho institucional, políticas e partidárias, efeito vizinhança, necessidade da política, organizações/atores sociais e fatores estruturais. Os resultados demonstram que, conforme varia o desenho institucional de coerção, mudam os fatores explicativos da difusão dessa política na ponta, de modo que os aspectos locais, incluindo atores sociais, fatores regionais e questões estruturais, importam para a difusão, variando conforme o contexto coercitivo.

Resumen Este artículo analiza la implementación de la Ley General de las Micro y Pequeñas Empresas por parte de los municipios de São Paulo. Se utilizó la teoría de la difusión de políticas, con el objetivo de estudiar el proceso de adopción de esta política pública, observando los diferentes contextos y momentos de coerción previstos en la legislación federal. A partir de las discusiones teóricas relacionadas con el mecanismo de difusión denominado coerción, se respondió a la siguiente pregunta: ¿cuál es la influencia del mecanismo de coacción vertical en la difusión de la mencionada ley en los municipios de São Paulo? Se aplicó la técnica de análisis de supervivencia para identificar factores explicativos de la difusión de políticas, considerando variables institucionales, políticas y partidarias, efecto barrio, necesidad de políticas, organizaciones/actores sociales y factores estructurales. Los resultados muestran que a medida que varía el diseño institucional de coerción, los factores explicativos de la difusión de esta política al final cambian, de modo que los aspectos locales, incluidos los actores sociales, los factores regionales y los problemas estructurales importan para la difusión, variando de acuerdo con el contexto coercitivo.

Abstract This article analyzes the implementation of the General Law for Micro and Small Business by municipalities in São Paulo. The theory of policy diffusion was used to study the process of adopting this public policy in the different contexts of coercion. The article presents theoretical discussions on the diffusion mechanism "coercion" and answers the question: what is the influence of the vertical coercion mechanism in the diffusion of the General Law in the municipalities of São Paulo? The survival analysis technique was applied to identify explanatory factors of policy diffusion, considering institutional, political, and party design variables, neighborhood effect, internal needs, organizations/social actors, and structural factors. The results show that as the institutional rules of coercion vary, the explanatory factors of the diffusion change so that local aspects, including social actors, regional factors, and structural issues, matter for the diffusion, varying according to the coercive context.

A segurança como fator-chave para a cidade inteligente, a confiança dos cidadãos e o uso de tecnologias / La seguridad como factor clave para la ciudad inteligente, la confianza de los ciudadanos y el uso de las tecnologías / Security as a key factor for the smart city, citizens' trust, and the use of technologies

Resumo As cidades inteligentes vêm crescendo ao redor do mundo, impulsionadas por inovações tecnológicas. Com elas surgem diversas oportunidades, mas também novas ameaças à segurança e privacidade do usuário nessa realidade interconectada. Este estudo tem como objetivo investigar a percepção de segurança e confiança na tecnologia por parte dos cidadãos e como esta afeta a propensão ao seu uso e, consequentemente, à vida na cidade inteligente. Para tanto, conduziu-se um survey (n = 601), por meio do método PLS-SEM, para testar as hipóteses formuladas. Os resultados obtidos confirmam que o modelo proposto demonstra ser consistente. As relações "confiança e segurança subjetiva" e "segurança objetiva e privacidade de dados" obtiveram relações mais consistentes, assegurando a forte influência das barreiras "tangíveis" e "intangíveis" da percepção de segurança. Dessa forma, para obter e manter a confiança dos usuários, as instituições por trás da tecnologia precisam estar atentas à opinião deles e da sociedade, de forma a manter uma boa reputação para que possam, assim, perpetuar uma percepção positiva de segurança. Conclui-se, assim, que o conceito de segurança adquire uma nova dimensão no contexto da cidade inteligente por ser um componente crucial para toda a sua base e estar intimamente ligado à tecnologia, além de se apresentar como uma preocupação fundamental para os governos e as entidades que buscam implementar soluções e aplicações do conceito.

Resumen Las ciudades inteligentes están creciendo en todo el mundo, impulsadas por las innovaciones tecnológicas. Con ellas surgen diversas oportunidades, pero también nuevas amenazas a nuestra seguridad y privacidad en esta realidad interconectada. Este estudio tiene como objetivo investigar la percepción de los ciudadanos sobre la seguridad y la confianza en las tecnologías y cómo afectan la propensión a usarlas y, en consecuencia, la vida en la ciudad inteligente. Para ello, se realizó una encuesta (n = 601) utilizando el método PLS-SEM para contrastar las hipótesis formuladas. Los resultados obtenidos confirman que el modelo propuesto resulta ser consistente. Las relaciones 'confianza y seguridad subjetiva' y 'seguridad objetiva y privacidad de datos' obtuvieron relaciones más consistentes, confirmando la fuerte influencia de las barreras 'tangibles' e 'intangibles' de la percepción de seguridad. De esta forma, para obtener y mantener la confianza de los usuarios, las instituciones que están detrás de las tecnologías deben estar atentas a su opinión y a la de la sociedad a los efectos de mantener una buena reputación, para que puedan, así, mantener una percepción positiva de la seguridad. Se concluye que el concepto de seguridad adquiere una nueva dimensión en el contexto de la ciudad inteligente, ya que es un componente crucial de toda su base, estrechamente vinculado a la tecnología además de presentarse como una preocupación fundamental para los gobiernos y entidades que buscan implementar soluciones conceptuales y aplicaciones.

Abstract Smart cities are growing around the world, driven by technological innovations. With them come several opportunities and new threats to our security and privacy in this interconnected reality. This study investigates citizens' perception of security and trust in technologies and how they affect the propensity to use them and, consequently, life in the smart city. Therefore, a survey was conducted (n = 601) using the PLS-SEM method to test the formulated hypotheses. The results obtained confirm that the proposed model proves to be consistent. The relationships between 'trust and subjective security' and 'objective security and data privacy' obtained stronger relationships, confirming the strong influence of the 'tangible' and 'intangible' barriers of the perception of security. Thus, to obtain and maintain users' trust, the institutions behind the technologies need to be attentive to the opinion of their users and society to keep a good reputation and a positive perception of security. The users' opinion is a crucial component of smart cities' entire base, closely linked to technology, and presents as a fundamental concern for governments and entities that seek to implement concept solutions and applications.
