O objetivo deste estudo é estimar as associações entre a escolaridade materna, como variável dependente, e algumas variáveis constantes na Declaração de Nascido Vivo (DNV) do Ministério da Saúde. Em uma análise de 3.843 DNV da região de Guaratinguetá, São Paulo, relativas a partos hospitalares e nascimentos únicos, ocorridos no ano de 1998, foram encontradas associações estatisticamente significativas entre a menor escolaridade e ocorrência de baixo peso ao nascer; número de filhos vivos igual ou maior que três; história pregressa de filhos mortos; maior número de partos e consultas médicas no pré-natal em número até seis. Não se observaram associações entre escolaridade e aborto e tempo de gestação, citadas em outros trabalhos. Assim, a escolaridade materna pode ser considerada um marcador obstétrico de risco para a gestante e o recém-nascido.

This paper aims to understand the current research scenario through published studies on corporate sustainability, emphasizing the environmental approach. Methodologically, this research develops a systematic literature review based on papers published in the Web of Science database in the last ten years. As a result, there was an upward evolution of research on the searched topic, with one hundred fifteen publications in the last three years compared to one hundred six documents published in the previous seven years. It is also observed that studies published at the beginning of the time frame between 2011 and 2020 were more concerned with the adoption of corporate sustainability, while the most recent research focuses on new approaches and methodologies for its implementation. And, with regard to its implementation, one of the main barriers is the incorrect perception of senior managers that the results from corporate sustainability must be more linked to the economic than to the environmental and social spheres. As relevant aspects, this study observed that new technologies, currently led by the 5th generation mobile network (5G) and Fourth Industrial Revolution (Industry 4.0), can contribute to the insertion of corporate sustainability in the industrial context. It also noted that, despite being recent, COVID-19 was considered by several researchers as an event to be considered in terms of corporate sustainability., Competing Interests: Conflict of interestThe authors have no relevant financial or non-financial interests to disclose and have no conflicts of interest to declare that are relevant to the content of this article., (© The Author(s), under exclusive licence to Springer Nature B.V. 2023, Springer Nature or its licensor (e.g. a society or other partner) holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.)

The Rio de Ondas Hydrographic Basin (ROHB), Bahia state, Brazil, is located in a region with abundant water resources and is highly impacted by intense agricultural activity. In such a scenario, the use of organochlorine pesticides can represent a potential risk to the aquatic environments, due to their persistence, high bioaccumulation capacity, and high toxicity. Thus, organochlorine pesticide residues in bottom sediment samples from rivers on eighteen sites distributed along the ROHB in the dry and rainy periods were analyzed by gas chromatography coupled with mass spectrometry. The validated method showed no matrix effect, recoveries ranging from 82% (β-HCB) to 118% (DDD), limits of detection between 0.003 ng g -1 (α-HCH) and 0.011 ng g -1 (DDT), limits of quantification of 0.010 ng g -1 (α-HCH) to 0.036 ng g -1 (DDT), repeatability with the highest relative standard deviation of 0.97% (α-hexachlorocyclohexane at 2.000 ng g -1 ), and inter-day precision ranging from 10% (aldrin at 0.050 ng g -1 and 0.600 ng g -1 and α-endosulfan at 0.600 ng g -1 ) to 25% (β-endosulfan at 0.050 ng g -1 ). Although most compounds were banned since 1985, it was observed that their residues were widely distributed in the ROHB, with the total concentrations varying from 3.242 ng g -1 (P02) to 12.052 ng g -1 (P17) and from 0.313 ng g -1 (P14) to 30.861 ng g -1 (P13) in the dry and rainy periods, respectively, which may be related to historical contamination and/or prohibited use. Moreover, the spatiotemporal variation showed the highest concentrations of organochlorine pesticide residues in the rainy season, coinciding with the planting period., (© 2022.

This article aims to describe the epidemiological profile and the spatial distribution of deaths and confirmed cases of COVID-19 in the health macroregion of Western Bahia. An ecological study on the inland expansion of SARS-CoV-2 was performed from March 21, 2020 to March 31, 2021 considering incidence and mortality rate, case fatality rate, case density and moving average of cases and deaths. 37,036 cases and 536 confirmed deaths were registered. Of all cases, 94.5% recovered and 4.0% remained active. The incidence rate was 3884.1/100,000 inhabitants, the mortality rate 56.2/100,000 inhabitants and the fatality rate was 1.4% A predominance of very high and high intensity of the occurrence of COVID-19 in the macroregion was identified and moving average revealed an increasing trend. Findings show a high risk of infection and death in the macroregion, in addition to a growing trend in accumulated cases, confirming the inland expansion of the disease.

The determination of some pesticides in surface sediments can provide important information about their distribution in the water column. This work aimed to determine the distribution of the classes of pesticides along the Ondas River's hydrographic basin (ORHB), in eighteen different points, during the dry and rainy periods. The pesticides were extracted from the sediment samples by solid-liquid extraction and then analyzed using a gas chromatograph coupled to mass spectrometry. After the development and validation of the method, nineteen pesticides from the group of organochlorine, organophosphates, carbamate and thiocarbamate, pyrethroids, and strobilurins were quantified in at least one point in the two collection periods, with accuracy varying between 86 and 126%. The average concentrations were 0.020 ng g -1 (carbofuran) to 249.123 ng g -1 (dimethoate) and 0.029 ng g -1 (carbofuran and sulfotep) to 533.522 ng g -1 in the dry and rainy periods, respectively. The results showed a wide distribution of pesticide residues in the ORHB, with higher levels for dimethoate, phenitrothion, and malathion, which may be related to their agricultural use in the region. In Brazil, it does not have specific legislation for maximum permitted values of pesticides in sediment, allowing for inappropriate or prohibited use and, consequently, affecting water quality.
