Existe relação entre ética e biossegurança ocupacional?

Tendo em vista a importância de uma conduta que atenda aos padrões de segurança e do comportamento adequado no que se refere à prevenção de acidentes em ambientes destinados a serviços de saúde, o presente trabalho se concentra em apresentar a relação entre a ética e a conduta ocupacional. A maior dificuldade em prevenir ou diminuir a recorrência de acidentes em laboratórios não está nas tecnologias disponíveis para minimizar os riscos, mas no comportamento dos profissionais. E, ainda, é fundamental a valorização da biossegurança e das relações sociais de trabalho em ambientes de serviços de saúde para prevenção de agravos

BovCria: an application designed to assist breeders in the assessment of beef cattle herds

The aim of this study was to develop a technological tool in the form of a mobile application that provides functionalities for the easy calculation of reproductive and productive efficiency indices. This tool aims to assist breeders, technicians, and students of agricultural sciences in decision-making for the challenges faced in cattle production systems. The application was developed using the Android Studio development environment and the Dart programming language framework known as Flutter. The application's graphical interface follows Google guidelines in the Material Design documentation. The tool will provide a practical way to calculate recognized indexes of productive efficiency of cow-calf systems and provide information such as goals and management tips to help users achieve better results. The impact of the developed product is its use as an information platform, facilitating decision-making in the area of beef cattle production and as an efficient means of disseminating technologies generated by research institutions and popularizing science. Thus, the application is an accessible and comprehensible tool, providing a means of evaluating the technologies and management practices adopted in beef cattle farms

Salmon mass mortality events and occupational health and safety in Chilean aquaculture

Mass mortality events (MMEs) threaten the health of fish and are also a potential threat to the health and safety of workers. This paper presents findings from a desktop risk assessment exercise focused on potential aquaculture occupational health and safety (AOHS) hazards and risks associated with MMEs in Chile. The study reviews academic and grey literature, government regulations and MME reports and statistics to assess the scale and distribution of MMEs; identifies associated documented and potential health and safety hazards; and documents and assesses policy responses to MMEs in the Chilean context through the lens of health and safety. The paper documents the size and regional distribution of salmon MME occurrences in Chile from 2016 to 2022. It discusses AOHS hazards associated with MMEs such as exposure to hydrogen sulfide, drowning and diving-related illnesses and potential issues around accessing hospitals and hyperbaric chambers for workers in remote aquaculture regions, as well as exposure to antibiotics and antibiotic residues. Recent Chilean regulatory requirements around reporting and management of MMEs that have the potential to help reduce identified MME-related risks for workers are described and addressed. Key policy highlights Risk of mass mortality events (MMEs) in marine aquaculture is increasing as the industry expands and climate change increases fluctuations in marine conditions. Policies need to be developed to counteract these risks. MMEs-related worker accidents and environmental degradation point to the urgent need to develop environmental and occupational health and safety (OHS) guidelines that prevent MMEs and protect workers and the environment. The Chilean OHS guidelines related to aquaculture MMEs may be adapted and used in other countries. Surveillance programs on harmful algal blooms and antibiotic resistance (AMR) markers may be a preventive measure towards MMEs and exposure to AMR markers

Evaluation of white spot syndrome virus (wssv) in wild shrimp after a major outbreak in shrimp farms at laguna, southern Brazil

O vírus da síndrome da mancha branca (WSSV) infectou camarões da espécie Litopenaeus vannamei cultivados em fazendas na região de Laguna, sul do Brasil, causando enormes perdas econômicas. O objetivo deste estudo foi verificar a presença, ou não, do vírus no camarão selvagem presente no sistema estuarino de Laguna, que recebe efluentes das fazendas de camarão.As amostras foram coletadas no verão de 2006 (fevereiro – 48 camarões juvenis) e no inverno (agosto – 66 juvenis). A presença do vírus foi testada por PCR “single-step” e “nested” nos 114 animais selvagens de três espécies diferentes (Farfantepenaeus paulensis, Farfantepenaeus brasiliensis e Litopenaeus schmitti). Todas as amostras foram negativas para os métodos de PCR empregados, indicando que a prevalência desta doença em animais selvagens deve ser menor de 5% por período de amostragem, ou menor que 3%, se considerarmos o número total de camarões amostrados. Os resultados sugerem que WSSV não deve estar distribuído extensamente entre os camarões nativos, mesmo após a grande dispersão da doença nas fazendas. Entretanto, mais esforços são necessários a fim de confirmar esses resultados.White spot syndrome virus (WSSV) infected Litopenaeus vannamei cultivated in ponds at Laguna, Southern Brazil, and caused huge economical losses. The objective of this study was to determine if WSSV infected wild shrimp were present in the Laguna estuarine system, which receives effluents of the shrimp farms. Samples were collected in the 2006 austral summer (February – 48 juvenile shrimp) and winter (August – 66 juvenile shrimp). Virus presence was tested by one-step and nested PCR in the 114 wild shrimp of three different species (Farfantepenaeus paulensis, Farfantepenaeus brasiliensis and Litopenaeus schmitti). All samples were negative for PCR method employed, indicating that prevalence of this disease in wild animals must be smaller than 5% per sampling period, or smaller than 3% when considering total number of tested shrimp (114 shrimp). So far, we may say that WSSV is not widely spread among native shrimp, even after strong disease outbreak in farms. However, more efforts need to be made in order to confirm these results

First report of White spot syndrome virus in farmed and wild penaeid shrimp from Lagoa dos Patos estuary, southern Brazil

In this study, we detected White spot syndrome virus (WSSV) in wild Farfantepenaeus paulensis collected in the Lagoa dos Patos estuary and cultivated Litopenaeus vannamei. This is the first report of WSSV in F. paulensis from Lagoa dos Patos and farmed L. vannamei shrimps in Rio Grande do Sul

Fish Balistes capriscus skin extract-induced relaxation in mesenteric arterial bed of rat

The vasorelaxing activity of the aqueous extract of fish Balistes capriscus skin (AEBc) on mesenteric arterial bed (MAB) of rats was studied. The bolus injections of AEBc (bolus of 5.1, 10.2, 20.5, and 41.1 mg) significantly inhibited, in a concentration-dependent manner, the maximal contractile response induced by methoxamine (30 M) in MAB. The vasodilatation action of AEBc is not mediated through -adrenoceptors or cyclo-oxigenase, since it was not affected by propranolol (20 M) or diclofenac sodium (3 M). The vasodilator response induced by subsequent addition of AEBc Balistes capriscus in bolus was significantly reduced in water infusion for endothelium removal. Treatment with an inhibitor of NO synthase (l-NAME, 10 M) decreased AEBc effect. The guanylate cyclase inhibitor methylene blue (MB, 100 M) had no significant effect on AEBc-induced vasodilatation. These results suggest that the vasorelaxing effect of AEBc is mediated by endothelium-dependent (NO/EDRF) and endothelium-independent neurally induced vasorelaxation from nonadrenergic and noncholinergic nerves (NO)
