Cardiovascular risk management in the peri‐operative setting
Authors: Mahendran Shehane , Thiagalingam Aravinda , Hillis Graham , Halliwell Richard , Pleass Henry CC , Chow Clara K 
Published: June 2023

SummaryPeri‐operative cardiovascular events occur in up to 3% of patients undergoing non‐cardiac surgery.Accurate cardiovascular risk assessment is important in the peri‐operative setting, as it allows informed and shared decisions regarding the appropriateness of proceeding with surgery, guides surgical and anaesthetic approaches, and may influence the use of preventive medications and post‐operative cardiac monitoring. Quantitative risk assessment may also inform a reconsideration of choosing a more limited lower risk type of surgery, or conservative management.Pre‐operative cardiovascular risk assessment starts with clinical assessment and should include an estimate of functional capacity.Specialised cardiac investigations are rarely indicated specifically to assess pre‐operative cardiovascular risk. The decision regarding cardiac investigations is influenced by the nature, extent and urgency of surgery.The strategy of performing pre‐operative revascularisation to improve post‐operative outcomes is not evidence‐based and recent international guidelines recommend against this.

AbstractObjectivesTo estimate the health care and societal costs of inherited retinal diseases (IRDs) in Australia.Design, setting, participantsMicrosimulation modelling study based on primary data — collected in interviews of people with IRDs who had ophthalmic or genetic consultations at the Children's Hospital at Westmead or the Save Sight Institute (both Sydney) during 1 January 2019 – 31 December 2020, and of their carers and spouses — and linked Medicare Benefits Schedule (MBS) and Pharmaceutical Benefits Schedule (PBS) data.Main outcome measuresAnnual and lifetime costs for people with IRDs and for their carers and spouses, grouped by payer (Australian government, state governments, individuals, private health insurance) and type (health care costs; societal costs: social support, National Disability Insurance Scheme (NDIS), income and taxation, costs associated with caring for family members with IRDs); estimated annual national cost of IRDs.ResultsNinety‐four people (74 adults, 20 people under 18 years; 55 girls and women [59%]) and 30 carers completed study surveys (participation rate: adults, 66%; children, 66%; carers, 63%). Total estimated lifetime cost was $5.2 million per person with an IRD, of which 87% were societal and 13% health care costs. The three highest cost items were lost income for people with IRDs ($1.4 million), lost income for their carers and spouses ($1.1 million), and social spending by the Australian government (excluding NDIS expenses: $1.0 million). Annual costs were twice as high for people who were legally blind as for those with less impaired vision ($83 910 v $41 357 per person). The estimated total annual cost of IRDs in Australia was $781 million to $1.56 billion.ConclusionAs the societal costs associated with IRDs are much larger than the health care costs, both contributors should be considered when assessing the cost‐effectiveness of interventions for people with IRDs. The increasing loss of income across life reflects the impact of IRDs on employment and career opportunities.
We Don’t Do that Here: Using Role Playing and Character Battle Drills to Develop Upstander Behavior at West Point
Authors: Spain Everett S. , Konheim-Kalkstein Yasmine L. , Erbe Ryan G. , Wilsey Corrine N. , Rosenberg Stacey F. 
Published: June 2023

Background: The Army is focused on the prevention of harmful interpersonal behaviors such as sexual harassment and sexual assault. Training soldiers who may witness these behaviors to intervene is considered paramount to the Army’s prevention efforts. Objective: To increase the propensity and efficacy of cadets (undergraduate college students) employing upstander behaviors when witnessing harmful interpersonal behaviors in less governed spaces, the United States Military Academy at West Point facilitated two scenario-based role-playing workshops to develop its cadets while piloting new methods of training intervention behaviors. Methods: Both workshops had cadets improvise roles as upstanders, perpetrators, victims, and witnesses. The first workshop focused on developing cadets’ propensity (courage) to intervene and intentionally provided cadets with little guidance on if and how they should intervene, allowing them to develop their own workable intervention strategies and skills. The second workshop focused on developing cadets’ effectiveness during an intervention by having them apply the new Character Battle Drill (CBD) concept, which is a specific sequence of action steps to follow, including specific scripts to say during an intervention. Results: In both workshops, cadets reported higher levels of engagement than traditional forms of bystander training. Conclusions: Improvisational role playing seems promising for future training. Lessons-learned, limitations, and areas of future research are discussed.

Pemalsuan uang banyak terjadi pada uang kertas dilakukan dengan berbagai cara. Kegiatan pemalsuan uang dinilai sangat merugikan terutama untuk kepentingan umum. Pelaku yang melakukan kegiatan pemalsuan uang dapat diberikan hukuman dan perbuatan tersebut masuk ke dalam tindak pidana. Studi ini bertujuan untuk mengetahui menyebabkan tindak pemalsuan mata uang atau uang kertas dan penegakan hukum pidana terhadap pelaku pemalsuan mata uang atau uang kertas serta upaya penanggulangan tindak pidana pemalsuan mata uang atau uang kertas di Kelurahan Lai-lai Besi Kopan, Kecamatan Kota Lama, Kota Kupang. Penulis ingin mengkaji dan meneliti secara mendalam bagaimana penegakan hukum pidana terhadap pelaku tindak pidana pemalsuan mata uang atau uang kertas. Jenis penelitian yang digunakan yaitu menggunakkan penelitian yuridis empiris dengan menggunakan pendekatan kasus. Informan dalam penelitian ini yakni penyidik dari Polsek Kelapa Lima. Sumber data yang digunakan adalah data primer dan data sekunder. Teknik pengumpulan data yang digunakan adalah wawancara dan studi kepustakaan. Hasil penelitian ini menunjukan bahwa Penegakan Hukum Terhadap Pelaku Tindak Pidana Pemalsuan Mata Uang Atau Uang Kertas Di Kelurahan Lai-Lai Besi Kopan, Kecamatan Kota Lama Kota Kupang yaitu : penegakan hukum tidak dilaksanakan sesuai dengan amanat perundang- undangan, bahwa perbuatan terdakwa merupakan pengulangan tindak pidana pemalsuan uang atau residive, namun pada isi putusan akhir peerkara pada sidang Pengadilan Negeri Kupang tidak menjatuhkan hukuman yang memberatkan terdakwa sehingga perlu diperhatikan pula rumusan pasal 486 KUHP dan terdakwa melakukan dua tindak pidana yakni memalsukan mata uang atau uang kertas dan tindak mengedarkan serta membelanjakan uang palsu tersebut namun hanya dijatuhkan hukuman atas tindak pemalsuan mata uang atau uang kertas. Sehingga belum sesuai dengan Pasal 244 KUHP. Sehingga berdasarkan teori yang dikemukakan oleh Satjipto Raharjo (2000;175-183) tentang penegakkan hukum pada Pengadilan Negeri Kupang tidak melaksanakan hukum secara konkrit dalam kehidupan masyarakat dan tidak menjatuhkan hukuman yang dapat memberi efek jera kepada pelaku tindak pidana

O presente estudo foi realizado na bacia hidrográfica do Rio Matipó, um afluente do Rio Doce, em Minas Gerais – Brasil. O principal objetivo foi avaliar a contaminação microbiológica das águas da bacia devido à influência da atividade humana. Para tal, foram realizadas amostragens de água em 25 estações de monitoramento situadas ao longo do curso hídrico em períodos sazonais distintos. Essas amostragens possibilitaram mensurar variáveis químicas e microbiológicas das águas. A análise dos dados obtidos permitiu observar a limitação dos usos da água da bacia hidrográfica pelo fato de estar contaminada com microrganismos, alguns potencialmente patogênicos. Os impactos ambientais verificados na bacia hidrográfica, como criação de animais nas margens e, principalmente, lançamento de esgoto sanitário sem tratamento, foram os principais fatores que interferiram na limitação dos usos da água para balneabilidade e para o abastecimento público.

Abstract
The present study wascarried outin the Matipó river watershed, a tributary of the Doce river, in Minas Gerais,Brazil. The main objective was to evaluate the microbiological contamination of waters of the basin due to the influence of human activities. In order to do so, water sampling was performed in 25 sampling stations along the water course in distinctseasonal periods. These samples made it possible to measure chemical and microbiological variables of the waters. The analysis of the obtained data allowed to noticethe limitation of the water uses inthe watershed due to contamination withmicroorganisms, some potentially pathogenic. The environmental impacts observed in the watershed, such as livestock famingon the banks and mainlythe release of untreated domestic sewage were the main factors that interfered with the limitation of water usefor leasure purposes and public supply.

Published: June 2023

O presente estudo teve como objetivo caracterizar o comportamento das vazões nas bacias hidrográficas dos rios Paraopeba (SF3) e Velhas (SF5), analisando a ocorrência de eventos extremos de máxima e mínima, bem como as tendências das séries históricas de vazões. Para isso, as séries históricas de vinte e uma estações fluviométricas presentes nas bacias foram analisadas. Foram determinadas as seguintes vazões: média de longa duração (Qmld) e mínima média de sete dias consecutivos, associada a um período de retorno de 10 anos (Q7,10). Posteriormente, foi avaliado o período chuvoso referente ao ano hidrológico de 2019/2020, bem como a ocorrência de vazões abaixo da Q7,10 para os anos de 2019 e 2020. Por fim, foi avaliada a estacionariedade dos dados de vazão utilizando o teste de Pettitt e a correlação de Spearman. Os resultados mostraram que o ano hidrológico pode ser definido de outubro a setembro, em ambas as bacias hidrográficas avaliadas. O período chuvoso do ano hidrológico de 2019/2020 foi caracterizado pelos altos valores de vazão nos cursos d’água, apresentando os maiores valores de vazão já registrados em algumas estações. Na bacia do rio Paraopeba foi observado significativas condições de restrição efetiva de uso dos recursos hídricos no ano de 2019, com menores ocorrências na bacia do rio das Velhas. Com a análise das tendências foi possível observar que o período seco tende a se intensificar nas bacias do rio Paraopeba e rio das Velhas.

The purpose of the present study is to characterize the behavior of the flow in the basins of Paraopeba (SF3) and Velhas (SF5) rivers, analyzing the occurrence of extreme maximum and minimum events, as well as the trends of the historical flow series. For that, the historical series of twenty-one stream gauge stations present in the basins were analyzed. The following flows were determined: long-term average (Qmld) and average minimum of seven consecutive days, associated with a 10-year return period (Q7.10). Subsequently, the rainy period for the hydrological year 2019/2020 was evaluated, as well as the occurrence of flows below Q7.10 for the years 2019 and 2020. Finally, the stationarity of the flow data was evaluated using the Pettitt test and Spearman's correlation. The results showed that the hydrological year can be defined from October to September, in both analyzed basins. The rainy period of the 2019/2020 hydrological year was characterized by high flow rates in water courses, reaching the highest flow rates ever recorded in some stations. In the Paraopeba basin, significant conditions of effective restriction in the use of water resources were observed in 2019, with lower occurrences in the Velhas basin. With the analysis of the trends it was possible to observe that the dry period tends to be intensified in the basins of Paraopeba and Velhas rivers.

Authors: Cerezini Monise Terra 
Published: June 2023

A segurança hídrica é o objetivo central da Política Nacional de Recursos Hídricos no Brasil e considera as dimensões humana, econômica, ecossistêmica e de resiliência, sendo compreendida como a garantia de acesso a água em termos de quantidade e qualidade adequados para abastecimento, alimentação, preservação de ecossistemas e demais usos, considerando os riscos em nível aceitável para as pessoas, economias e meio ambiente. A pandemia provocada pelo novo Coronavírus e o consequente isolamento social e desaceleração econômica acentuou ainda mais as desigualdades sociais brasileiras. Nesse sentido, a segurança hídrica é questão fundamental para alcançar o acesso universal a serviços de oferta de água, indispensáveis para prover meios de subsistência fundamentais para manter a qualidade de vidas dos seres humanos.

Water security is a central issue of Water Policy in Brazil and considers the human, economic, ecosystem and resilience dimensions. This concept is understood as the guarantee of access to water in terms of adequate quantity and quality for supply, food, preservation ecosystems and other uses, considering risks at an acceptable level for people, economies and the environment. The pandemic caused by the new Coronavirus and the resulting social isolation and economic slowdown further accentuated brazilian social inequalities. In this sense, water security is a fundamental issue in order to achieve universal access to water supply services, which are essential to provide basic means of subsistence to maintain the life quality of human beings and ecosystems.

A presente nota técnica científica tem por objetivo avaliar a qualidade das águas do rio Paraopeba, impactados pelos rompimentos das barragens de rejeito, provenientes da Mina de Córrego do Feijão, da mineradora Vale S.A., em Brumadinho, Minas Gerais, decorridos dois ciclos hidrológicos. O monitoramento mostrou que o trecho de aproximadamente 40 km de extensão (distância medida desde as barragens que romperam), entre os municípios de Brumadinho e São Joaquim de Bicas, foi totalmente impactado, inviabilizando o uso da água. Nos três últimos períodos sazonais (período seco/2020, períodos chuvoso e seco/2021), observa-se que os valores de turbidez, manganês, ferro e chumbo ainda permanecem acima dos limites de Classe 2. Contudo, os registros desses parâmetros já se aproximam dos valores da série histórica do Igam, do período pré-rompimento ao longo da calha do rio Paraopeba.

Abstract
The present scientific note aimed to assess water quality in the Paraopeba River, impacted by tailings released from the ruptured of Córrego do Feijão Dam (Brumadinho, Minas Gerais), in two hydrological cycles. The results demonstrated impacts on water supply for the municipalities provided by the Paraopeba River, aproximately 40 km of extension from dam rupture, between Brumadinho and São Joaquim de Bicas. Over the last three seasonal periods (january/2020 to april/2021), concentration of turbidity, manganese, iron and lead above legislation limits were perceived. Nevertheless, these concentrations are already near to what had been noticed previously, according to the historical series in Paraopeba River recorded by Igam (Minas Gerais Water Management Institute) before the dam rupture.
