Abstract. Background: Few reports from developing countries have described long-term trends in suicide. Aims: To investigate the age-, sex-, and method-specific trends in suicide over the period 1904–2017 in São Paulo. Method: Mortality data were obtained from SEADE, DATASUS, and PRO-AIM. Results: Suicide peaked in the mid-1910s and mid-1950s, being higher among men. There was an upward trend from the 1920s for men and from the 1930s for women. Suicide rates have declined since the mid-1950s, reaching lower rates in the past 40 years. Men aged 60+ had higher rates at the beginning and a decreasing trend. Suicide rates among men aged 20–39 and 40–59 peaked in the mid-1950s and declined until the late 1970s, thereafter remaining stable. Women aged 20–39 years had the highest rates with decreasing trends from the mid-1950s. No trends were detected for the age group 40–59, and women aged 60+ presented a decreasing trend. Rates among women aged 0–19 declined after the late 1970s. Suicide by poisoning peaked in the 1950s, and there was a downward trend for firearms and an upward trend for hanging. Conclusion: Suicide trends vary by sex, age group, and method. Accurate monitoring of these trends is an important task for suicide prevention and public health agencies and personnel.

Air pollution is one of the main environmental problems in large urban centers, affecting people’s health and impacting quality of life. The Metropolitan Area of São Paulo (MASP) presents frequent exceedances of air-quality standards in inhalable particulate matter (PM10), a consequence of pollutant emissions modulated by meteorological conditions. This study aims to identify and characterize PM10persistent exceedance events (PEE) inthe MASP between 2005 and 2017, relating them to meteorological conditions. The criteria used to select the events were: (i) events that occurred in at least 50% of the air-quality monitoring stations chosen for this study and, (ii) among the events that met the first criterion, those with a duration equal to or greater than five days, which correspond to the 80% percentile of the event duration distribution. A total 71 persistent episodes of exceedance were selected. The results show that the exceedance of PM10 lasted up to 14 consecutive days and was predominant in the austral winter, accompanied by an increase in maximum temperature (T), a decrease in wind speed (WS) and relative humidity (RH), and a wind direction predominantly from the northwest during the peak concentration of the pollutant. On average, a concentration increase of 60% was observed at the peak of the PEE.

SUMMARYSeroprevalence of Toxocara and Taenia solium and risk factors for infection with these parasites were explored in a long-term rural settlement in São Paulo state, Brazil. An ELISA for the detection of anti-Toxocara IgG and IgE and anti-T. solium cysticerci was standardized using Toxocara excretory-secretory antigens (TES) obtained from the cultured second-stage larvae of T. canis and by vesicular fluid antigen from Taenia crassiceps cysticerci (VF). For cysticercosis, the reactive ELISA samples were assayed by Western blot using 18 kDa and 14 kDa proteins purified from VF. Out of 182 subjects, 25 (13·7%) presented anti-Toxocara IgG and a positive correlation between total IgE and the reactive index of specific anti-TES IgE (P=0·0265) was found amongst the subjects found seropositive for anti-Toxocara IgG. In these individuals 38·0% showed ocular manifestations. The frequency of anti-T. solium cysticerci confirmed by Western blot was 0·6%. Seropositivity for Toxocara was correlated with low educational levels and the owning of dogs. Embryonated eggs of Toxocara spp. were found in 43·3% of the analysed areas.

Abstract. The objective of this work is to evaluate the impact of vehicular emissions on the formation of fine particles (PM2.5;  ≤  2.5 µm in diameter) in the Sao Paulo Metropolitan Area (SPMA) in Brazil, where ethanol is used intensively as a fuel in road vehicles. The Weather Research and Forecasting with Chemistry (WRF-Chem) model, which simulates feedbacks between meteorological variables and chemical species, is used as a photochemical modelling tool to describe the physico-chemical processes leading to the evolution of number and mass size distribution of particles through gas-to-particle conversion. A vehicular emission model based on statistical information of vehicular activity is applied to simulate vehicular emissions over the studied area. The simulation has been performed for a 1-month period (7 August–6 September 2012) to cover the availability of experimental data from the NUANCE-SPS (Narrowing the Uncertainties on Aerosol and Climate Changes in Sao Paulo State) project that aims to characterize emissions of atmospheric aerosols in the SPMA. The availability of experimental measurements of atmospheric aerosols and the application of the WRF-Chem model made it possible to represent some of the most important properties of fine particles in the SPMA such as the mass size distribution and chemical composition, besides allowing us to evaluate its formation potential through the gas-to-particle conversion processes. Results show that the emission of primary gases, mostly from vehicles, led to a production of secondary particles between 20 and 30 % in relation to the total mass concentration of PM2.5 in the downtown SPMA. Each of PM2.5 and primary natural aerosol (dust and sea salt) contributed with 40–50 % of the total PM10 (i.e. those  ≤  10 µm in diameter) concentration. Over 40 % of the formation of fine particles, by mass, was due to the emission of hydrocarbons, mainly aromatics. Furthermore, an increase in the number of small particles impaired the ultraviolet radiation and induced a decrease in ozone formation. The ground-level O3 concentration decreased by about 2 % when the aerosol-radiation feedback is taken into account.

ABSTRACT Background: Azathioprine is a common first-line therapy for neuromyelitis optica spectrum disorder (NMOSD). Objective: The aim of this study was to determine whether long-term treatment (>10 years) with azathioprine is safe in NMOSD. Methods: We conducted a retrospective medical record review of all patients at the School of Medicine of the University of São Paulo (São Paulo, Brazil) who fulfilled the 2015 international consensus diagnostic criteria for NMOSD and were treated with azathioprine for at least 10 years. Results: Out of 375 patients assessed for eligibility, 19 were included in this analysis. These patients’ median age was 44 years (range=28-61); they were mostly female (17/19) and AQP4-IgG seropositive (18/19). The median disease duration was 15 years (range=10-39) and most patients presented a relapsing clinical course (84.2%). The median duration of treatment was 11.9 years (range=10.0-23.8). The median annualized relapse rates (ARR) pre- and post-treatment with azathioprine were 1 (range=0.1-2) and 0.1 (range=0-0.35); p=0.09. Three patients (15.7%) had records of adverse events during the follow-up, which consisted of chronic B12 vitamin deficiency, pulmonary tuberculosis and breast cancer. Conclusion: Azathioprine may be considered a safe agent for long-term treatment (>10 years) of NMOSD, but continuous vigilance for infections and malignancies is required.

Abstract: Mental disorders are associated with employment status as significant predictors and as consequences of unemployment and early retirement. This study describes the estimates and associations of 12-month DSM-IV prevalence rates of mental disorders and use of health services with employment status by gender in the São Paulo Metropolitan Area, Brazil. Data from the São Paulo Megacity Mental Health Survey was analyzed (n = 5,037). This is a population-based study assessing the prevalence and determinants of mental disorders among adults, using the Composite International Diagnostic Interview. The associations were estimated by odds ratios obtained through binomial and multinomial logistic regression. This study demonstrates that having mental disorders, especially mood disorders, is associated with being inactive or unemployed among men and inactive among women, but only having a substance use disorder is associated with being unemployed among women. Among those with mental disorders, seeking health care services is less frequent within unemployed.

Através de uma análise das atividades desenvolvidas pelos terapeutas da zooterapia, apresentado pela experiência de um trabalho de observação de longa duração, este artigo se propõe a colocar em questão a associação do homem e do animal, em um corpus de conhecimentos vindo de uma “etologia” empírica e de um corpus elaborado e estruturado de saberes antropológicos. A zooterapia enquanto mediação animal é uma técnica de cuidado para além de uma constatação trivial interespecífica ou de uma projeção antropomórfica sobre os animais de categorias universalmente reconhecidas como humanas. Ela permite nos interrogarmos sobre o recurso à participação animal e seu estatuto de sujeito dotado de capacidades agentivas, ao lado de um terapeuta humano e face à uma pessoa doente. Por ocasião de três estudos de caso contextualmente situados nas cidades de Porto Alegre, Rio de Janeiro e São Paulo, destacamos a questão mais geral da interação entre os dados empíricos que a zooterapia acumula e as representações sociais que são implicitamente mobilizadas para situar o animal dentro de uma cadeia operativa. De modo geral a problemática de interesse deste artigo trata das práticas e horizontes relacionais que atravessam vários grupos sociais e indivíduos contemporâneos que apostam na direção de uma relação interespecífica. Essa problemática é também empírica e epistemológica, pois demarca uma remodelação das diferenças entre natureza e cultura, baseada em uma conjunção de fenômenos invocados a caracterizar os sujeitos (conduta, ações, afetos, comportamento).Palavras-chave: Antropologia da natureza. Agentividade dos animais. Zooterapia. Modalidades de ações.The interspecific relations for human care in the conventional health system: an anthropological analysis of the dynamics of zootherapyAbstractThrough an analysis of the activities developed by zootherapy therapists, presented by the experience of a long-term work of observation, this article proposes to put in question the association of man and animal, in a corpus of knowledge coming from an empirical "ethology" and an elaborate and structured anthropological knowledge corpus. The zootherapy as an animal care mediation is a technique other than an interspecific trivial finding, or an anthropomorphic projection on animals of universally recognized as human categories. It allows us to interrogate about the use of animals and their status as subjects endowed with agentive capacities, alongside a human therapist and in face of a sick person. Based on three case studies contextually located in the cities of Porto Alegre, Rio de Janeiro and São Paulo, we highlight the more general question of the interaction between the empirical data that zootherapy accumulates and social representations that are implicitly mobilized to locate the animal inside of an operative chain. More comprehensively the issue of interest in this paper deals with the practical and relational horizons that cut across social groups and contemporary individuals who bet on the direction of an interspecies relationship. This problem is also empirical and epistemological because it marks a remodel of the differences between nature and culture, based on a combination of phenomena invoked to characterize the subjects (behavior, actions, feelings).Keywords: Anthropology of nature. Animal agency. Zootherapy. Modalities of actions.

Abstract. The notable increase in biofuel usage by the road transportation sector in Brazil during recent years has significantly altered the vehicular fuel composition. Consequently, many uncertainties are currently found in particulate matter vehicular emission profiles. In an effort to better characterize the emitted particulate matter, measurements of aerosol physical and chemical properties were undertaken inside two tunnels located in the São Paulo Metropolitan Area (SPMA). The tunnels show very distinct fleet profiles: in the Jânio Quadros (JQ) tunnel, the vast majority of the circulating fleet are Light Duty Vehicles (LDVs), fuelled on average with the same amount of ethanol as gasoline. In the Rodoanel (RA) tunnel, the particulate emission is dominated by Heavy Duty Vehicles (HDVs) fuelled with diesel (5% biodiesel). In the JQ tunnel, PM2.5 concentration was on average 52 μg m−3, with the largest contribution of Organic Mass (OM, 42%), followed by Elemental Carbon (EC, 17%) and Crustal elements (13%). Sulphate accounted for 7% of PM2.5 and the sum of other trace elements was 10%. In the RA tunnel, PM2.5 was on average 233 μg m−3, mostly composed of EC (52%) and OM (39%). Sulphate, crustal and the trace elements showed a minor contribution with 5%, 1% and 1%, respectively. The average OC:EC ratio in the JQ tunnel was 1.59 ± 0.09, indicating an important contribution of EC despite the high ethanol fraction in the fuel composition. In the RA tunnel, the OC:EC ratio was 0.49 ± 0.12, consistent with previous measurements of diesel fuelled HDVs. Besides bulk carbonaceous aerosol measurement, Polycyclic Aromatic Hydrocarbons (PAHs) were quantified. The sum of the PAHs concentration was 56 ± 5 ng m−3 and 45 ± 9 ng m−3 in the RA and JQ tunnel, respectively. In the JQ tunnel, Benzo(a)pyrene (BaP) ranged from 0.9 to 6.7 ng m−3 (0.02–0.1‰ of PM2.5) in the JQ tunnel whereas in the RA tunnel BaP ranged from 0.9 to 4.9 ng m−3 (0.004–0.02‰ of PM2.5), indicating an important relative contribution of LDVs emission to atmospheric BaP. Real-time measurements performed in both tunnels provided aerosol size distributions and optical properties. The average particle count yielded 73 000 cm−3 in the JQ tunnel and 366 000 cm−3 in the RA tunnel, with an average diameter of 48 nm in the former and 39 nm in the latter. Aerosol single scattering albedo, calculated from scattering and absorption observations in the JQ tunnel, showed a minimum value of 0.4 at the peak of the morning rush hour, reached 0.6 around noon and stabilized at 0.5 in the afternoon and evening. Such single scattering albedo range is close to other tunnel studies results, despite significant biofuel usage. Given the exceedingly high Black Carbon loadings in the RA tunnel, real time light absorption measurements were possible only in the JQ tunnel. Nevertheless, using EC measured from the filters a single scattering albedo of 0.32 for the RA tunnel has been estimated. The results presented here characterize particulate matter emitted from nearly 1 million vehicles fuelled with a considerable amount of biofuel, providing an unique experimental site worldwide.
