<p>During COVID – 19 pandemic, the main strategy to prevent virus dissemination adopted worldwide was the social distancing, in different degrees (ranging from simple recommendations to the population, to complete lockdown). In this context, many studies were performed around the world to assess the impacts of such measures on the environment, specially on air quality. The reported results almost unanimously pointed to a reduction in air contaminants, mainly as a response to vehicular traffic depletion and, at some level, to reduced human and industrial activities.  On March 24<sup>th</sup>, 2020, a partial lockdown was decreed in São Paulo state, Brazil, and since then it has undergone, back and forth, several stages of strictness according to contamination and hospitalization rates, being stricter whenever intensive care units (ICU) occupation increased. Our study aims to evaluate environmental aspects (air quality and meteorology) in Campinas city (São Paulo, Brazil), during the pandemic, from March 24<sup>th</sup> to December 31<sup>st</sup>, and compare it with the weeks prior to the social distancing and with the previous year. In addition to the environmental variables, the “social distancing index” (obtained by using mobile phone data to assess displacements) and medical data (hospital admissions and deaths) were employed to a preliminary analysis of  the influence of environmental factors on COVID – 19 evolution in the city.</p>

Abstract BackgroundThe association between environmental factors and asthma has attracted much attention. Numerous studies have focused on the effects of air pollution or meteorological factors, but the synergistic effects and regional heterogeneity remain unclear. MethodsBetween 2014 and 2015, 8,563 hospital admissions in 2014 and 7,804 hospital admissions in 2015 due to asthma were collected from 14 regions in Guangxi, China. First, we performed a Spearman correlation coefficient model as the single factor analysis to estimate correlation between environmental factors and asthma hospitalization rates in multiple regions. Second, Generalized Additive Model (GAM) was used to analyze the synergistic effects of environmental factors on asthma hospitalization rates in 14 regions, respectively.ResultsThe results indicated that asthma hospitalization rates were high in spring and autumn. There were all nonlinear relationships between air pollutants, meteorological factors and asthma hospitalization rates, and the relationships were different from region to region. According to the single factor analysis, asthma hospitalizations were related to the daily temperature, daily range of temperature, CO, NO2, and PM2.5 in multiple regions. According to the result of synergistic effects analysis, the adjusted R-square was high in Beihai and Nanning, with values of 0.292 and 0.207, which meant that environmental factors were powerful in explaining changes of asthma hospitalization rates in Beihai and Nanning.ConclusionDaily range of temperature is an important factor impact on asthma, which should be considered in the analysis of environmental factors impact on asthma. It is suggested that the relationship between asthma and risk factors in different regions deserves additional study. Governments should develop targeted protective measures for asthma in different regions.

Abstract Background The concentration of child morbidity and mortality due to pneumonia in developing countries reflects the social inequities, which lead to greater exposure to risk factors and make access to prevention, diagnosis and treatment of the disease more difficult. This study aimed to map and assess the territorial risk for hospitalization due to Community-Acquired Pneumonia in children under 5 years of age. Methods Ecological study, carried out in the city of Ribeirão Preto, state of São Paulo, Brazil. The study population consisted of hospitalized children under the age of five, diagnosed with community-acquired pneumonia, in Ribeirão Preto-São Paulo-Brazil, from 2012 to 2013. Data were collected in different databases, by a trained team, between March 2012 and August 2013 and from the 2010 Demographic Census of the Brazilian Institute of Geography and Statistics. The 956 urban census tracts were considered as the units of analysis. Descriptive statistics were performed for the sociodemographic characteristics, with the calculation of measures of absolute frequency and proportions for the categorical variables, using the Statistica software (12.0). The incidence of cases per 10,000 inhabitants was calculated by census tracts during the study period. For the identification of the spatial risk clusters, the Kernel density estimator and the Getis-Ord Gi* technique were measured from the Radius of the distance of 7,589 km, with p < .01, found using the Incremental Spatial Autocorrelation tool. Results The study included 265 children under the age of five, hospitalized due to community-acquired pneumonia. A concentration of cases was identified in the regions with greater social vulnerability (low income, poor housing conditions and homelessness), as well as a lower occurrence of cases in the most developed and economically privileged area of the city. The majority of the children lived in territories served by traditional primary healthcare units, in which the health surveillance and family and community focus are limited. Conclusions The results contribute to the comprehension of the social factors involved in child hospitalization due to pneumonia, based on the analysis of the spatial distribution, and address the interface with individual and institutional factors.

COVID 19 has caused social distancing and lead to the reductions of various anthropogenic activities. Correspondingly this study has two fold objectives. First, aims to provide quantification measurement of social distancing impacts on air quality. Second, to forecast the air quality if social distancing is continued. The measured air quality parameters consist of NO2, SO2, and O3. According to the results, the order of air quality parameters was NO2&lt;SO2&lt;O3. The NO2, SO2, and O3 levels were observed lower after social distancing than before social distancing was implemented. The reductions of NO2, SO2, and O3 levels were 5%, 3%, and 5% respectively. Likewise, 65% of study periods (30 days) after implementation of social distancing have lower NO2 than before social distancing. The exponential smoothing forecasts show the decreasing trends for NO2 and SO2. While O3 levels are estimated will remain stable after social distancing. This study has shown that the social distancing has an impact on the NO2, SO2, and O3. Correspondingly, if the social distancing is continued, then it is estimated can provide a positive impact on urban quality. Keywords: COVID 19, forecast, NO2, O3, SO2.

Abstract The clinical severity of sickle cell disease (SCD) is dependent on genetic and environmental variables. The impact of environmental factors on disease is a major public health issue and air pollution has been consistently correlated with poor health outcomes. Environmental factors in SCD have been poorly studied. We have retrospectively studied the numbers of daily admissions with vaso-occlusive sickle cell pain to King’s College Hospital, London, in relation to local daily air quality measurements. We analysed 1047 patient episodes over 1400 days (1st January 1998 to 31st October 2001). Statistical time series analysis was performed using cross-correlation function (CCF), where the observations of one series are correlated with the observations of another series at various lags and leads, values >0.05 being significant. This showed a significant association between increased numbers of admissions and low levels of nitric oxide (NO) (CCF=0.063), low levels of carbon monoxide (CO) (CCF=0.064) and high levels of ozone (O3) (CCF=0.067). There was no association with sulphur dioxide (SO2), nitric dioxide (NO2) or dust. The significant results were further examined using quartile analysis. This confirmed that increased numbers of hospital admissions were associated with high levels of O3 (oneway ANOVA p=0.039) and low levels of CO (oneway ANOVA p=0.042). Low NO levels were also associated with increased admissions, not however reaching statistical significance on quartile analysis (oneway ANOVA p=0.158). O3 levels show marked seasonal variation, with high levels occurring in summer months in the UK. We have previously shown a trend towards increased admissions in the summer months with acute sickle related pain, whereas other groups, which are primarily based in rural tropical climates, found increased admissions in cold, rainy months. The adverse effect of high O3 levels may explain this difference. There is no direct evidence to explain the mechanism by which high O3 levels leads to vaso-occlusion in SCD but high levels of O3 have been linked to reduced respiratory function, which may in turn precipitate vaso-occlusion. Independent studies have shown high CO levels are linked to increased respiratory and cardiovascular admissions. Paradoxically we found that high CO levels were linked to decreased admission numbers and may be protective against acute pain in SCD. CO may confer benefit by forming carboxyhaemoglobin that cannot polymerise resulting in decreased sickling. Previous studies have shown prolonged red cell survival in vivo following administration of CO to patients with SCD. Our study also suggests higher levels of atmospheric NO are linked to fewer admissions. NO is known to be central in the pathophysiology of vaso-occlusion and sickle cell patients are thought to have functional deficiency of NO. Many groups have reported inhaled NO as beneficial in the treatment of sickle pain. Our study suggests air quality has a significant effect on acute pain in SCD and that patients should be counselled accordingly. Based on these findings it would be appropriate to warn patients that high O3 levels might precipitate complications of SCD. The potential beneficial effect of CO and NO is intriguing and requires further investigation.

O objetivo desse trabalho é analisar o crescimento da cana-de-açúcar no município de Rio Brilhante-MS, correlacionando esse crescimento com os impactos ambientais causados pela técnica de facilitação da colheita manual com a queima da palha da cana-de-açúcar. Para compreendermos o processo expansionista canavieiro, analisamos os incentivos do governo estadual e do governo federal, por meio do Banco Nacional de Desenvolvimento Econômico e Social, Fundo Constitucional do Centro-Oeste e pelo Programa de Aceleração do Crescimento. Também foram analisados dados estatísticos de órgãos públicos, entidades e intuições da área. Como considerações, foi possível demonstrar que a queima da palha da cana-de-açúcar se tornou um dos fatores que, acompanhados dos aspectos sociais e ambientais, decorrentes do processo de expansão dessa monocultura no Estado, ocasionou várias formas de degradação ambiental com alto potencial de risco a fauna e flora, além de ser prejudicial ao próprio ser humano, gerando consequências como: invasão de Biomas e as Áreas de Preservação Permanente ou de Preservação Ambiental, além da contaminação dos recursos hídricos, dos solos e poluição do ar, dando indícios que os ganhos econômicos muitas vezes se sobrepõem a um ambiente saudável. Palavras-chave: Cana-de-açúcar; Impactos Ambientais; Queima da palha.   the sugarcane GROWTH in the municipality of Rio Brilhante-MS and the environmental impacts caused by burning straw of the sugarcane (2001 to 2010) Abstract The objective of this study is to analyze the growth of sugarcane in the city of Rio Brilhante-MS, correlating this growth with environmental impacts caused by manual harvesting facilitation technique with the burning straw of the sugarcane. To understand the sugarcane expansionist process, its analyzed the incentives from the state government and the federal government, through the National Bank for Economic and Social Development, the Constitutional Fund of the Midwest and the Growth Acceleration Program. Also statistical data from government agencies were analyzed, as entities and intuitions of the area. As consideration, it was possible to demonstrate that the burning of straw sugarcane became one of the factors that, together with the social and environmental aspects arising from the expansion of this monoculture process in the state, led to various forms of environmental degradation with high potential risk fauna and flora as well as being harmful to human being, generating consequences as: Biomes invasion and the Permanent Preservation Areas or Environmental Protection, and the contamination of water resources, soil and pollution of the air, giving evidence that the economic gains often overlap with healthy environmental. Keywords: Sugar cane; Environmental impacts; Straw burning.   LA CROISSANCE DU SECTEUR cannier DANS LA MUNICIPALITÉ DE rIO BRILHANTE-MS ET LES IMPACTS ENVIRONNEMENTAUX CAUSÉS PAR LE BRÛLAGE DE LA PAILLE DE CANNE À SUCRE (2001 À 2010) Résumé Ce travail a pour but d’analyser le processus d’expansion de la canne à sucre dans la municipalité de Rio Brilhante-MS, en faisant un rapprochement entre cette croissance et les impacts environnementaux provoqués par la technique d’optimisation de la récolte manuelle, à savoir le brûlage de la paille de canne à sucre. Afin de mieux comprendre le processus d’expansion du secteur cannier, nous soumettons à l’analyse les programmes de soutien du gouvernement régional et du gouvernement fédéral, menés par la Banque Nationale de Développement Économique et Social, Fonds Constitutionnel de la région Centre-Ouest et par le Programme d’Accélération de la Croissance. Nous examinons également les données statistiques des organes publiques, entités et institutions concernés par le secteur cannier. Cette étude a pu démontrer que la technique de brûlage de la paille de canne à sucre est devenue, à côté des aspects sociaux et environnementaux découlant du processus d’expansion de cette monoculture dans la région, l’un des facteurs qui se trouvent à l’origine des formes diverses de dégradation environnementale à haut risque sur la faune et la flore, en plus des effets nuisibles pour l’être humain lui-même, parmi lesquels l’invasion de biomes et de zones de préservation permanente ou de préservation environnementale, la contamination des ressources hydriques, des sols et la pollution de l’air, ce qui indique que les gains économiques devancent souvent un environnement sain. Mots-clés: Canne à sucre; Impacts environnementaux; Brûlage de paille.

Respiratory diseases are the leading cause of hospitalizations in Brazil (excluding hospital admissions related to childbirth, pregnancy, and postpartum). To analyze the trend and seasonality of hospitalizations for respiratory diseases in Salvador, Bahia State, Brazil, 1998-2009, a time trend study was performed using simple linear regression. Hospitalization rates for all respiratory diseases and specifically for asthma, chronic obstructive pulmonary disease (COPD), and pneumonia were calculated by year and age group. Hospitalizations for all respiratory diseases decreased by 45.6% (β = -2.2; p < 0.001); those due to asthma showed the largest decline (annual average 1.2/10,000), pneumonia showed the largest reduction until 2002, subsequently tending to stabilize, and COPD remained unchanged. The under-5-year age group showed the largest decline in hospitalizations for all respiratory diseases. There was no seasonality in hospitalizations for COPD. There was a reduction in the burden of hospitalizations due to respiratory diseases in Salvador, mainly due to the drop in asthma and pneumonia in children < 5 years. However, the city still has hospitalization rates for respiratory diseases that are higher than in other large Brazilian cities.

Abstract Objectives: To analyze the association between ambient temperature, air humidity and atmospheric pollution with the incidence of hospital admissions for stroke in the city of São Paulo in 2016. Results: An average in the year 2016 was observed for CO of 0.58 ppm (SD = 0.12), not exceeding 0.81 ppm. For MP10, there was an annual average of 28, 26 μg / m3 (SD = 7.13), ranging from 20, 45 μg / m3 to 42.81 μg / m3. MP2.5 had a mean of 2016 of 13.40 μg / m3 (SD = 5.01). SO2 had an annual average of 1,90 μg / m3 (SD = 0,90), with a minimum of 1,20 μg / m3 and a maximum of 4,20 μg / m3. It is observed that the higher incidence values of stroke were stated in the colder and drier months at the year between May and August, that is evident looking for the female incidence of 769 in August and the male incidence of 8.92 in July. This fact matches with high concentrations of the pollutants, mostly SO2 that had the most relevant value of 4.2 μg / m3 in July.

To detect outbreaks of diseases in public health, several control charts have been proposed in the literature. In this context, the usual generalized linear model may be fitted for counts under a Negative Binomial distribution with a logarithm link function and the population size included as offset to model hospitalization rates. Different statistics are used to build CUSUM control charts to monitor daily hospitalizations and their performances are compared in simulation studies. The main contribution of the current paper is to consider different statistics based on transformations and the deviance residual to build control charts to monitor counts with seasonality effects and evaluate all the assumptions of the monitored statistics. The monitoring of daily number of hospital admissions due to respiratory diseases for people aged over 65 years in the city São Paulo-Brazil is considered as an illustration of the current proposal.

AbstractWe quantify the causal impact of human mobility restrictions, particularly the lockdown of the city of Wuhan on January 23, 2020, on the containment and delay of the spread of the Novel Coronavirus (2019-nCoV). We employ a set of difference-in-differences (DID) estimations to disentangle the lockdown effect on human mobility reductions from other confounding effects including panic effect, virus effect, and the Spring Festival effect. We find that the lockdown of Wuhan reduced inflow into Wuhan by 76.64%, outflows from Wuhan by 56.35%, and within-Wuhan movements by 54.15%. We also estimate the dynamic effects of up to 22 lagged population inflows from Wuhan and other Hubei cities, the epicenter of the 2019-nCoV outbreak, on the destination cities’ new infection cases. We find, using simulations with these estimates, that the lockdown of the city of Wuhan on January 23, 2020 contributed significantly to reducing the total infection cases outside of Wuhan, even with the social distancing measures later imposed by other cities. We find that the COVID-19 cases would be 64.81% higher in the 347 Chinese cities outside Hubei province, and 52.64% higher in the 16 non-Wuhan cities inside Hubei, in the counterfactual world in which the city of Wuhan were not locked down from January 23, 2020. We also find that there were substantial undocumented infection cases in the early days of the 2019-nCoV outbreak in Wuhan and other cities of Hubei province, but over time, the gap between the officially reported cases and our estimated “actual” cases narrows significantly. We also find evidence that enhanced social distancing policies in the 63 Chinese cities outside Hubei province are effective in reducing the impact of population inflows from the epi-center cities in Hubei province on the spread of 2019-nCoV virus in the destination cities elsewhere.JEL CodesI18, I10.
