Mechanical circulatory and/or respiratory assistance with extracorporeal membrane oxygenation (ECMO) has become a standard of care for patients with circulatory (venoarterial) and/or respiratory (venovenous) failure refractory to standard therapies. Adult patients with congenital heart disease are an increasingly recognized and growing population and include various groups, such as undiagnosed cases in childhood and palliated and/or corrected cases, which require subsequent care because of residual lesions, cardiac arrest/insufficiency, and arrhythmias, among other conditions. In addition, these patients are prone to developing pathologies that are typical of adulthood with a generally increased risk of morbidity and mortality because of their low reserves and organic damage associated with the underlying heart disease, which makes them candidates for ECMO. These patients represent an additional challenge in this therapy because malformations and the presence of a shunt can generally affect the usual cannulation methods and hemodynamic and oximetry monitoring. Thus, the configuration decision must be made on a case-by-case basis. Here, we present a cannulation method, venopulmonary artery ECMO, which provides hemodynamic and respiratory support, and may be ideal for patients with shunts and/or right ventricular dysfunction. To our knowledge, this is the first report of this configuration in patients with congenital heart diseases.

Cheaper Precision Weapons: An Exploratory Study about the HESA Shahed 136

引用

Advances in Aerospace Science and Technology 2024年第1期9卷 40-59页

作者： daniel Zampronha Aline Albuquerque National Institute for Applied Sciences Rouen Normandie Rouen France Programme of Pos-Graduation in Bioethics University of Brasília Brasília Brazil

The ability to hit a target with precision and from a great distance has been reserved for the world’s superpowers. However, this resource is increasingly being threatened as drones with this long-range and precision capability are becoming more accessible to those who don’t have this strategic ability. This article starts with an analysis of the Iranian HESA Shahed 136 drone to discuss the latest innovations in low-cost long-range precision weapons, specifically the use of kamikaze drones and loitering munitions. This is an exploratory study that starts by discussing the notion of a kamikaze drone and then analyses the design options for the Shahed 136, to reflect on the future of this new type of weapon and its implications for the economic and political relationship between weapon and cost. The conclusion is that the HESA Shahed 136 revolutionizes the concept of precise long-range strikes, a function that until now was reserved for expensive and technologically demanding tactical missiles and aircraft, and which can now be carried out with cheap drones. This creates an arms race not only in producing the most technological and precise weaponry but also the least expensive.

Evaluation of a hepatic biomarker of nutritional imbalance in juvenile red drum(Sciaenops ocellatus) fed 60% soybean meal-based diets using NMR-based metabolomics

A 12-week feeding trial with juvenile red drum(Sciaenops ocellatus) fed high-soybean meal(SBM) diets was conducted to investigate a putative biomarker of nutritional imbalance, N-formimino-L-glutamate(FIGLU). Three fishmeal-free, 60% SBM pelleted diets(named B12, Fol, and Met, respectively) were tested to evaluate the effects on growth performance and tissue metabolite profiles of supplementation of vitamin B12(0.012 mg/kg), folate(10 mg/kg), methionine(1 g/kg) respectively, above basal supplementation levels. A fourth SBM-based diet(named B12/Fol/Met) was formulated with a combination of B12, folate, and methionine to attain the above-mentioned target concentrations. A fifth 60% SBM diet(named FWS) with methionine supplementation(1 g/kg above basal supplementation levels), enriched with taurine, lysine and threonine as well as minerals, was also tested. This diet contained formulation targets and additives which have allowed for replacing fishmeal with plant proteins in rainbow trout feeds. Control diets included a fishmeal-based diet(named FM), an unsupplemented basal 60% SBM diet(named SBM60), and a “natural” diet(named N) made up of equal parts of fish(cigar minnows), squid and shrimp as a positive reference for growth performance. Formulated feeds contained approximately 37% total crude protein, approximately 14% total crude lipid and were energetically balanced. Standard growth performance metrics were measured, and tissues(liver, muscle) were collected at week 12 to evaluate diet-induced metabolic changes using nuclear magnetic resonance(NMR)-based *** results show that the FWS diet outperformed all other SBM diets and the FM diet under all performance metrics(P<0.05). FIGLU was not detected in fish fed the N diet but was detected in those fed the SBM diets and the FM diet. Fish fed the FWS diet and the Met diet showed lower hepatic levels of FIGLU compared with the other SBM-based diets(P<0.05), suggesting that among the different supplementatio

To the Editor : Barcelona Clinic Liver Cancer(BCLC) Stage C hepatocellular carcinoma(HCC) with vascular invasion has been considered unresectable. However, the curative rate from systemic treatment is rather dismal. Even with the use of immunotherapy, complete remission is less than 10% [ 1 ]. On the contrary, recent advances in transplant oncology, especially in the application of liver transplant-related surgical techniques in complex liver resections, make the operation possible for patients with locally advanced HCC who were previously considered to be unresectable [ 2 ]. We hereby present the surgical management of a patient with giant HCC in right liver lobe with inferior vena cava(IVC) invasion.
