Introduction and objectives: Cardiogenic shock (CS) complicates 5–10% of cases of myocardial infarction (MI). Whether glycoprotein IIb/IIIa inhibitors (GPIs) are beneficial in these patients is controversial. Our aim is to assess the prognostic impact of GPI use on in-hospital mortality and outcomes in patients with MI and CS undergoing percutaneous coronary intervention (PCI). Methods: Between October 2010 and December 2019, 27 578 acute coronary syndrome (ACS) patients were included in the multicenter Portuguese Registry of Acute Coronary Syndromes. Of these, 357 with an MI complicated by CS were included in the analysis and grouped based on whether they received GPI therapy (with GPI, n=107 and without GPI, n=250). The primary endpoint was in-hospital mortality. Secondary endpoints included successful PCI and in-hospital reinfarction and major bleeding. Results: Demographics and cardiovascular risk factors did not differ between groups. ST-elevation MI patients were more likely to receive GPIs (95% vs. 83%, p=0.002). In-hospital mortality was similar between groups (OR 1.80, 95% CI 0.96–3.37). Only age and the use of inotropes or intra-aortic balloon pump were predictors of mortality. Also, no differences between groups were noted for successful PCI (OR 0.33, 95% CI 0.62–4.06), reinfarction (OR 0.77, 95% CI 0.15–3.90), or major bleeding (OR 1.68, 95% CI 0.75–3.74). Conclusion: The use of GPIs in the context of MI with CS did not significantly impact in-hospital outcomes. Resumo: Introdução e objetivos: O choque cardiogénico (CC) complica 5-10% dos enfartes agudos do miocárdio (EAM). O benefício do uso de inibidores da glicoproteína IIb/IIIa (GPI) nestes doentes é controverso. O nosso objetivo é avaliar o impacto prognóstico do uso de GPI nos outcomes intra-hospitalares em doentes com EAM e CC submetidos a intervenção coronária percutânea (ICP). Métodos: Entre outubro de 2010 e dezembro de 2019, 27 578 doentes com síndrome coronária aguda (SCA) foram incluídos no Registo Português de SCA. Destes, 357 com EAM complicado por CC foram incluídos. Dois grupos foram criados, baseados no facto de terem recebido terapêutica com GPI (GPI, N=107 e sem tratamento com GPI, N=250). O endpoint primário foi a mortalidade intra-hospitalar. Endpoints secundários incluíram sucesso de ICP, re-enfarte e hemorragia major. Resultados: As características demográficas e os fatores de risco cardiovasculares não diferiram entre grupos. Doentes com EAM com supra-ST receberam mais terapêutica com GPI (95% versus 83%, P=0,002). A mortalidade intra-hospitalar foi similar entre grupos (OR 1,80, 95% CI 0,96-3,37, P=0,068). Apenas a idade, uso de inotrópicos ou balão intra-aórtico foram preditores de mortalidade. Não houve diferenças para sucesso de ICP (OR 0,33, 95% CI 0,62-4,06); re-enfarte (OR 0,77, 95% CI 0,15-3,90) ou hemorragia major (OR 1,68, 95% CI 0,75-3,74). Conclusão: O uso de GPI no contexto de EAM com CC não teve impacto significativo nos outcomes intra-hospitalares.

This paper presents an automated Non-Destructive Testing (NDT) system for the in-service inspection of orbital welds on tubular components operating at temperatures as high as 200 °C. The combination of two different NDT methods and respective inspection systems is here proposed to cover the detection of all potential defective weld conditions. The proposed NDT system combines ultrasounds and Eddy current techniques with dedicated approaches for dealing with high temperature conditions. Phased array ultrasound was employed, searching for volumetric defects within the weld bead volume while Eddy currents were used to look for surface and sub-surface cracks. The results from the phased array ultrasound results showed the effectiveness of the cooling mechanisms and that temperature effects on sound attenuation can be easily compensated for up to 200 °C. The Eddy current results showed almost no influence when temperatures were raised up to 300 °C.

Under controlled laboratory conditions, toxicity data tend to be less variable than in more realistic in-field studies and responses may thus differ from those in the natural environment, creating uncertainty. The validation of data under environmental conditions is therefore a major asset in environmental risk assessment of chemicals. The present study aimed to validate the mode of action of a commercial fungicide formulation in the soil invertebrate F. candida, under more realistic exposure scenarios (in-field bioassay), by targeting specific molecular biomarkers retrieved from laboratory experiments. Organisms were exposed in soil cores under minimally controlled field conditions for 4 days to a chlorothalonil fungicide dosage causing 75% reduction of reproduction in a previous laboratory experiment (127 mg a.i. kg−1) and half this concentration (60 mg a.i. kg−1). After exposure, organisms were retrieved and RNA was extracted from each pool of organisms. According to previous laboratorial omics results with the same formulation, ten genes were selected for gene expression analysis by qRT-PCR, corresponding to key genes of affected biological pathways including glutathione metabolism, oxidation-reduction, body morphogenesis, and reproduction. Six of these genes presented a dose-response trend with higher up- or down-regulation with increasing pesticide concentrations. Highly significant correlations between their expression patterns in laboratory and in-field experiments were observed. This work shows that effects of toxicants can be clearly demonstrated in more realistic conditions using validated biomarkers. Our work outlines a set of genes that can be used to assess the early effects of pesticides in a realistic agricultural scenario.

Spiders are generalist predators that contribute to the control of pests in agroecosystems. Land use management determines habitats including refuges for hibernation and aestivation. The availability of shelters on the ground can be crucial for maintaining populations of spider within crops. We studied the effect of the number of stones on the surface of the soil on the spider community in selected olive groves in Trás-os-Montes (northeastern Portugal). The number of stones significantly influenced the overall diversity of spiders, abundance of immature individuals and abundance of ground hunters. Agricultural management practices aimed at the conservation of soil microhabitats such as hedgerows, stonewalls and stones on the ground should be promoted in order to maintain or increase the number of shelters for potential natural enemies of pests.
