EXAME MACROSCÓPICO DAS ARTICULAÇÕES DE SUÍNOS ARTRÍTICOS NO ABATEDOURO

Realizou-se um estudo macroscópico das articulações dos membros torácicos e pélvicos e respectivos linfonodos de suínos recém-abatidos em um matadouro localizado em Concórdia SC. incluiu-se no presente estudo todos os suínos que foram desviados da linha de abate, por suspeita de artrite. Dos 23.393 suínos abatidos, 140 (0,5%) foram desviados para o departamento de inspeção final, por suspeita de artrite. Deste total constatou-se: 70% de artrite causada pela osteocondrose, 21% artrite infecciosa, 3% artrite infecciosa e osteocondrose simultaneamente, 1% apresentaram artrite traumática, 3% artrite sem diagnóstico conclusivo e 2% apresentaram-se com as articulações normais. As artrites causadas pela osteocondrose caracterizaram-se pelo grande volume de líquido sinovial e pelas áreas focais de dobras, abas e úlceras na cartilagem articular. As artrites infecciosas caracterizaram-se pela reação nos linfonodos regionais e pela moderada a acentuada hipertrofia da membrana sinovial. O percentual de artrite causada pela osteocondrose foi superior ao encontrado em estudos anteriores e ressalta a necessidade de um diagnóstico diferencial com as artrites infecciosas a fim de se evitar a condenação desnecessária de carcaças. Macroscopic analysis of joints from arthritic swines pigs in the abattoir Abstract A macroscopic study of thoracic and pelvic limb articulations as well as regional lymph nodes was performed in recently-slaughtered swines at a slaughterhouse located in Concordia, SC, Brasil. A total of 23,393 carcasses were included in the study, 140 (0.5%) being diverted on the discharge line by the Department of Final Inspection as suspicious for arthritis. The analysis of the suspicious carcasses showed that 98 (70%) presented arthritis caused by ostechondrosis, 29 (21%) infectious arthritis, four (3%) infectious arthritis and ostechondrosis simultaneously, two (1%) traumatic arthritis, four (3%) presented arthritis with uncertain diagnosis and three (2%) showed normal articulations. The arthritis caused by the osteochondrosis was diagnosed by the increased volume of sinovial fluid and focal areas of folds, flaps and ulcers in the articular cartilage. The infectious arthritis was diagnosed by an inflammatory process involving regional limph nodes and by moderate to accentuated hypertrophy of the sinovial membrane. The percentage of arthritis caused by osteochondrosis was higher when compared to those found in previous studies. This fact emphasizes the need for a differential diagnosis between infectious arthritis and osteochondrosis in order to avoid the unnecessary condemnation of carcasses at slaughterhouses

Aproveitamento de um fosfato natural parcialmente solubilizado pela cultura da cana-de-açúcar: I. Cana-planta

The relative efficiency of a partially acidulated and granulated rock phosphate, FAPS, containing 26% total P2O5, 10% citric acid soluble P2O5, 13% ammonium citrate soluble P2O5, 27% total CaO and 7% total S, was compared with that of both simple superphosphate (SS) and ground rock phosphate (FA). The experiment with the sugar cane variety NA 56-79 was set in a red yellow latosol, pH 5.1-5.5, low in P (4 ppm), and with and average available sulphur content (5 ppm as sul fate). The main conclusions were as follows: a) FAPS gave the same yield results provided by SS when used at the same rates based on total P2O5 content; b) sucrose content in the juice was increased by the highest level (16a kg P2O5 of application of FAPS; c) leaf analyses data suggest that FAPS has incre ased yield by supplying both P2O5 and S to the sugar-cane crop.Em um latossolo, com teor de P disponível entre baixo e médio foi instalado um ensaio destinado a comparar a eficiência de um fosfato natural parcialmente acidulado (FAPS) com a do super simples (SS) e a do fosfato de Araxá (FA) original, na cultura da cana-de-açúcar (cana-planta). Os dados obtidos mostraram que: (1) o FAPS deu uma produção que não diferiu estatisticamente da obtida com o SS, sendo superior ao FA como fonte de P2O5; (2) os dados de diagnose foliar sugerem que o FAPS e o SS funcionam como fonte de P e de S; (3) o teor de açúcares redutores no caldo aumentou em consequência da adubação fosfatada; (4) o FAPS, na dose mais alta, elevou o teor de sacarose do caldo

Hotspots of soil pollution: possible glyphosate and aminomethylphosphonic acid risks on terrestrial ecosystems and human health

The study presents a literature review of glyphosate (GLY) occurrence and its breakdown product, aminomethylphosphonic acid (AMPA), in soils worldwide, but with a specific focus on South America. In addition, an ecological risk approach based on the ecotoxicological endpoints for key soil biota (e.g., collembolans, and earthworms) assessed the impact of GLY and AMPA on these organisms. A generic probabilistic model for human health risk was also calculated for the different world regions. For what reports the risk for edaphic species and the level of pollution under the worst-case scenario, the South American continent was identified as the region of most concern. Nonetheless, other areas may also be in danger, but no risk could be calculated due to the lack of data. Since tropical countries are the top food exporters worldwide, the results obtained in this study must be carefully examined for their implications on a global scale. Some of the factors behind the high levels of these two chemicals in soils are debated (e.g., permissive protection policies, the extensive use of genetically modified crops), and some possible guidelines are presented that include, for example, further environmental characterisation and management of pesticide residues. The present review integrates data that can be used as a base by policymakers and decision-makers to develop and implement environmental policies

Predictors of mortality in critically ill patients with COVID-19 and diabetes

The COVID-19 pandemic has challenged the entire world, and patients with diabetes mellitus (DM) have been particularly affected. We aimed to evaluate predictors of mortality during the first 30 days of hospitalization in critically ill patients with COVID-19 and comorbid DM. This prospective study included 110 critically ill patients admitted with COVID-19 infection. Thirty-two (29%) patients had a previous diagnosis of DM. Clinical variables, laboratory tests, and vascular biomarkers, such as VCAM-1, syndecan-1, ICAM-1, angiopoietin-1, and angiopoeitin-2, were evaluated after intensive care unit (ICU) admission. A comparison was made between patients with and without DM. No difference in mortality was observed between the groups (48.7 vs 46.9%, P=0.861). In the multivariate Cox regression analysis, VCAM-1 levels at ICU admission (HR: 1 [1-1.001], P<0.006) were associated with death in patients with DM. Among patients with DM, advanced age (HR 1.063 [1.031-1.096], P<0.001), increased Ang-2/Ang-1 ratio (HR: 4.515 [1.803-11.308] P=0.001), and need for dialysis (HR: 3.489 [1.409-8.642], P=0.007) were independent predictors of death. Higher levels of VCAM-1 in patients with DM was better at predicting death of patients with severe COVID-19 and comorbid DM, and their cut-off values were useful for stratifying patients with a worse prognosis. Vascular biomarkers VCAM-1 and Ang-2/Ang-1 ratio were predictors of death in patients with severe COVID-19 and comorbid DM and those without DM. Additionally, kidney injury was associated with an increased risk of death
