Knowledge about soil water availability for future planning is the basis for carrying out its rational use. This work aimed to study the spatiality of water precipitation, crop evapotranspiration, and the need for water supplementation in soybean cultivation in the microregions of Jales-SP and Andradina-SP for the summer harvest. The water balance was determined by the Thorthwaite and Mather (1955) method, with data made available by the Agrometeorological Stations Network operated by the Hydraulics and Irrigation area of UNESP Ilha Solteira. We considered an available water capacity (AWC) of 40 mm. The study took place from the simulation of the water condition of a soybean crop sown on November 4, 2020. In the water deficit condition, the actual evapotranspiration (ETa) was considered null at a 20 % deficit, and the other values followed the same mathematical proportion. The mean rainfall of the period, crop evapotranspiration, and water deficit of each weather station were interpolated through ordinary circular kriging in ArcGIS 10.7 software. The water deficit in the soybean crop in the northwest region of São Paulo is related to the poor distribution of precipitation during the cycle and the significant recurrence of Indian summers all through the area. For the producers’ safety, investment in irrigation systems anticipating this poor distribution is justified. The water deficit in the region is variable. In years with good rainfall distribution, it can reach zero values, and in years with poor distribution, it can reach values greater than 180 mm.

Epidemiological characteristics of canine rabies in the northwest region of São Paulo State (Araçatuba region), Brazil, from 1993 to 1997 are presented. Out of 1,984 dogs, a total of 351 (17.7%) were positive for rabies diagnosis; 89% (312/351) of these occurred in urban areas and 85% (266/312) of the urban positive cases were among owned dogs. The mean age of the rabid dogs was 34 months and 61% were male. Aggressive behavior was observed in 77% of rabid dogs, followed by lack of coordination and paralysis (42%) and 48% of these dogs were responsible biting people or other animals. Information about vaccination status was obtained from 182 records and 51% of rabid dogs were non-vaccinated. The number of unvaccinated rabid dogs indicates a low vaccination index and this factor added to the high dog/man ratio must have contributed to the canine rabies epizootic observed in the studied area.

Gastrointestinal nematode infections were evaluated in sheep raised in Botucatu, state of São Paulo, Brazil between April 2008 and March 2011. Every month, two tracer lambs grazing with a flock of sheep were exposed to natural infection with gastrointestinal nematodes for 28 consecutive days. At the end of this period, the lambs were sacrificed for worm counts. Haemonchus contortus presented 100% of prevalence. The seasons exerted no significant influence on the mean intensity of H. contortus, which ranged from 315 worms in November 2010 to 2,5205 worms in January 2011. The prevalence of Trichostrongylus colubriformis was also 100%, with the lowest mean intensity (15 worms) recorded in February 2011 and the highest (9,760 worms) in October 2009. In the case of T. colubriformis, a significant correlation coefficient was found between worm counts vs. rainfall (r = −0.32; P <0.05). Three other nematodes species were found in tracer lambs, albeit in small numbers. Their prevalence and mean intensity (in parenthesis) were as follows: Oesophagostomum columbianum 28% (25.2), Cooperia curticei 7% (4.5) and Trichuris spp. 2% (1). In conclusion, the environmental conditions of the area proved to be highly favorable for the year-round transmission of H. contortus and T. colubriformis.

Protozooplankton is an important component of the aquatic microbial food webs and its composition, density, and distribution reflect the chemical, physical, and biological aspects of the environment. Considering the scarce literature on freshwater protozoans in Brazil and on protozoan ecology in subtropical environments, we listed the ciliates and amoebae taxa found in 13 water bodies in São Paulo State and analyzed their abundance in relation to the environmental variables. We collected two samples in each environment, fixed immediately with mercuric chloride and stained with bromophenol blue. After microscopical analysis, 74 protozoan genera were identified and the Ciliophora were dominant in the majority of the environments. The Stichotrichia, represented mostly by the genus Halteria, occurred in all environments, and was the dominant subclass in five of them. The canonic correspondence analysis of the most frequent genera and the environmental variables showed that nitrite and nitrate were the variables that better explained the distribution of Limnostrombidium, Urotricha, and Vorticella. The densities of the genera Halteria, Coleps, and of the species Cinetochilum margaritaceum were positively affected by increasing concentrations of dissolved oxygen, particulate phosphate, conductivity, and temperature. C. margaritaceum were also negatively affected by increasing concentrations of nitrite and nitrate. Considering that we made only one sampling in each environment, the richness was high compared to the mean diversity of lakes in the São Paulo State. The Diogo Lake, located in an ecological reserve, was the richest one, confirming the need of more research on the biodiversity of more preserved environments.

Background: To identify geographical clusters of suicide in São Paulo, Brazil (2006–2015) and to verify the associations of suicide with sociocultural characteristics of its 96 districts. Methods: Spatial scan test was used to detect the geographical clusters. Correlation and multiple regression techniques were used to estimate the association of socioeconomic and cultural variables with suicide. Results: The mean suicide rate was 4.8/100,000. Three clusters were identified which are as follows: one of increased risk in downtown and two of decreased risk in the South and in the Southeast. The mean suicide rate of the high-risk clustered districts (7.99/100,000) presented significantly higher average incomes per household, higher proportion of formally educated, of no religious affiliation, of recent migrants, of all-times migrants and lower proportion of married. The multiple model selected two independent risk factors – people with no religious affiliation (β = 0.182) and of recent migrants (β = 0.278) – and two protective factors – the proportion of married (β = –0.185) and of total migrants (β = –0.075), which jointly explained 58.4% of the variance. Conclusion: Durkheimian social and cultural risk factors for suicide were confirmed. Compared to a previous study period (1996–2005), suicide rates and geographical clusters remained relatively stable in the subsequent decade (2006–2015).

In this study, a questionnaire was applied to patients from Ribeirão Preto Dental School, University of São Paulo, Brazil, to evaluate the hygiene methods and habits concerning the use of complete dentures, the age of dentures, and whether patients have been instructed on how to clean their dentures. The mean age of patients was 63.35 years, and most of them were females (82.08%). The results showed that 62.26% of the respondents had been using the same maxillary complete denture for more than 5 years, and 49.06% used the same mandible complete denture for more than 5 years. Of the patients interviewed, 58.49% slept with the dentures. Mechanical brushing was the most used cleaning method by the patients (100%), using water, dentifrice and toothbrush (84.91%). Most patients (51.89%) reported never having been instructed by their dentists as to how to clean their dentures. Based on the limitations of this study, it was concluded that the patients interviewed had limited knowledge about prosthetic hygiene and oral care. The method more used by patients was the mechanical method of brushing, most patients used the same complete dentures for more than 5 years and slept with the dentures.

Background: Studies have shown a sex difference in the cognitive dysfunction in the elderly where women are more susceptible to Alzheimer’s disease than men. Physical activity (PA) is an important strategy for brain health, but the exact mechanism is unclear. Santos has the largest proportion of the elderly population in São Paulo State (22%), but no studies have whether there are differences between the sexes in cognitive function. Objective: To evaluate the differences between the sexes in the cognitive function of the elderly and which factors are associated with this difference. Methods: Ninety-seven women and sixty-nine men were eligible for the study. Inclusion criteria were >65 years old, no severe cognitive impairment, preserved activities of daily living. Cognitive function and PA were assessed by the mini-mental state examination (MMSE) and Baecke questionnaire. Results: The mean age was 75±7 and 73±7, for women and men, respectively. Both sexes showed a similar MMSE score (26, varying between 14 and 30) that was inversely associated with age. The influence of the schooling status on MMSE was greater in women (r=0.49, p=0.0001) compared to men (r= 0.30, p9. Conclusions: The MMSE score is affected by the aging process similarly between the sexes. The years of schooling have an influence on cognitive function in women that is attenuated by higher PA.

One of the main factors influencing the occurrence of plant diseases is the leaf wetness duration (LWD). However, this climatic parameter is not generally and systematically recorded at meteorological stations, and the alternative to obtain an estimate for LWD is the use of mathematical models. The objective of this study was to estimate LWD for the State of São Paulo, on the basis of the number of hours with relative humidity equal to or higher than 90%, and also plot them on a map with help of the Geographical Information System (GIS) tool. Using daily relative humidity data from ten meteorological stations of the State, for six years, adjustment equations were obtained for different LWD periods (hours day-1) (R² from 0.58 to 0.81) and of number of days (ND) per month with LWD for a period equal to or higher than ten consecutive hours (R² from 0.57 to 0.75), both as functions of the mean relative humidity. The mean LWD and the mean ND varied among the different regions of the State and different periods of the year. The smallest estimated values of mean annual LWD and ND were observed for the west region of the State, and the highest values for the coastal region.

Este artigo tem o intuito de analisar a situação do saneamento básico em 2015 por meio de indicadores e sua relação com a dinâmica demográfica dos anos 2000 e 2015 na Unidade de Negócio Oeste (MO) da Companhia de Saneamento Básico do Estado de São Paulo (Sabesp) pelo uso do geoprocessamento. Foram criados mapas no software QGIS que possibilitaram a espacialização dos indicadores analisados para os anos de 2010 e 2015, os quais são: a) atendimento de água, b) atendimento de esgoto, c) perdas na distribuição, d) cobertura de co- leta direta de resíduos sólidos urbanos (RSU) e e) massa coletada de RSU. Houve um aumento na densidade populacional média da MO que saltou dos 5.414,73 hab./km² em 2000 para os 6.650,26 hab./km² em 2015, resultando em uma aglomeração maior de pessoas nas áreas urbanizadas. Dos indicadores, cinco tiveram uma relativa melhoria e um, o de perdas na distribuição, teve um retrocesso. A metodologia é útil para avaliar os in- dicadores, a servir como balizadora para estudos futuros em outras áreas operadas pela Sabesp. Palavras-chave: Esgotamento Sanitário.

This article intends to analyze the situation of basic sanitation in 2015 through indicators and its relation with the demographic dynamics of the years 2000 and 2015 in the Business Unit West (MO) of the Sanitation Company of the State of São Paulo (Sabesp) through the use of geoprocessing. The maps were created in the QGIS software that enabled the spatialization of the analyzed indicators for the years 2010 and 2015, which are: a) water supply, b) sewage service, c) distribution losses, d) direct collection of urban solid waste and e) mass collected from urban solid wasted. There was an increase in the mean population density of MO from 5,414.73 inhab./km² in 2000 to 6,650.26 inhab./km² in 2015, resulting in a larger population crowding in urbanized areas. Of the indicators, five had a relative improvement and one, the one of losses in the distribution, had a setback. The methodology is useful to evaluate the indicators, to serve as a beacon for future studies in other areas operated by SABESP. Keywords: Sanitary sewage. Drinking Water Supply. Solid Waste. Demographic Density. Geoprocessing.

ABSTRACT Objective: A resolution passed by the government of the Brazilian state of São Paulo established a protocol for requesting free COPD medications, including tiotropium bromide, creating regional authorization centers to evaluate and approve such requests, given the high cost of those medications. Our objective was to analyze the requests received by an authorization center that serves cities in the greater metropolitan area of (the city of) São Paulo between 2011 and 2016. Methods: Data regarding the authorization, return, or rejection of the requests were compiled and analyzed in order to explain those outcomes. Subsequently, the clinical and functional data related to the patients were evaluated. Results: A total of 7,762 requests for dispensing COPD medication were analyzed. Requests related to male patients predominated. Among the corresponding patients, the mean age was 66 years, 12% were smokers, 88% had frequent exacerbations, and 84% had severe/very severe dyspnea. The mean FEV1 was 37.2% of the predicted value. The total number of requests decreased by 24.5% from 2012 to 2013 and was lowest in 2015. Most (65%) of the requests were accepted. The main reasons for the rejection/return of a request were a post-bronchodilator FEV1/FVC ratio > 0.7, a post-bronchodilator FEV1 > 50% of the predicted value, and failure to provide information regarding previous use of a long-acting β2 agonist. During the study period, the total number of requests returned/rejected decreased slightly, and there was improvement in the quality of the data included on the forms. Conclusions: Here, we have identified the characteristics of the requests for COPD medications and of the corresponding patients per region served by the authorization center analyzed, thus contributing to the improvement of local public health care measures.
