Crude protein (CP) reduction and amino acid (AAs) supplementation is an interesting cost-reducing strategy for environmental compliance. The objective of this work is to study productive performances of heavy Duroc X (Landrace X Large white) male and female pigs during the finishing stage under a 2% CP reduction with crystalline AA supplementation. A total of 60 entire male and 60 female pigs (means ± standard deviations: 109 ± 4.

Pig production is one of the most important providers of high-quality proteins and amino acids (AAs) to human nutrition. In this sector, feeding has an important economic and environmental impact. A strategy to reduce production costs and negative sustainability effects is reducing dietary crude protein (CP) contents with or without AA supplementation.

Article Synopsis
  • * Key findings indicated that certain genetic variations in the TYK2 and VIP genes were linked to a reduced severity of the disease, while variations in TLR7 and OAS1 were associated with increased severity.
  • * The research suggests that these genetic markers could help identify individuals at greater risk for severe COVID-19 outcomes.

Purpose: Most data regarding infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI) comes from TAVI registries, rather than IE dedicated cohorts. The objective of our study was to compare the clinical and microbiological profile, imaging features and outcomes of patients with IE after SAVR with a biological prosthetic valve (IE-SAVR) and IE after TAVI (IE-TAVI) from 6 centres with an Endocarditis Team (ET) and broad experience in IE.

Methods: Retrospective analysis of prospectively collected data.

Two of the main issues related to cured meat products are castration to avoid boar taint and the hefty reliance on soybean meal to feed pigs. However, data on the effects of immunocastration in pigs and alternative crop protein feeds on the sensory traits and consumers' acceptance of dry-cured loin are still limited. A preliminary study was conducted on the effect of sex type (surgical castrated male pigs and immunocastrated male and female pigs, at approximately 140 kg in weight and 7 months of age) and animal diet (pea vs.

The fusariosis is an opportunistic mycosis caused by Fusarium spp. Its clinical presentation depends on the immunological status of the host, especially in patients with hematooncological diseases, whose manifestations vary from localized to invasive fungal infections. Skin or blood culture helps to guide combined antifungal treatment with amphotericin B and voriconazole.

This study aimed to evaluate the effects of dietary carob (Ceratonia siliqua L.) pulp and warm season on gastrointestinal morphological parameters, immune-redox defences and coccidiosis in concentrate-fed light lambs. Weaned lambs were assigned to one of three concentrate-based diets: C0 (without carob pulp), C15 (150 g/kg of carob pulp) and C30 (300 g/kg of carob pulp) from 40 to 80 days of age in two consecutive cold and warm batches.

There is a growing interest in using by-products rich in polyphenols, such as carob pulp (Cp, L.), as a dietary source of antioxidants for animals. This study assesses the effects of including Cp in lambs' diet and meat display time (0, 7, 9, and 11 days) in modified atmosphere packaging on meat colour, fatty acid (FA) composition, tocopherol levels, and lipid oxidation values in the muscle of 40 light lambs.

Article Synopsis
  • The primary treatment for severe asthma exacerbations with respiratory failure includes both invasive and non-invasive ventilatory support alongside asthma medications, with mortality rates of 6.5% to 10.3% for those needing invasive ventilation.
  • Significant improvements in asthma management have led to a decrease in mortality rates, but in critical cases where conventional treatments fail, advanced options like ECMO and ECCO2R are necessary.
  • ECMO can reduce ventilator-associated lung injury and allow for important diagnostic procedures, while ECCO2R has gained popularity as an alternative treatment for both children and adults with severe respiratory failure due to asthma.

Bacterial resistance to antibiotics has been rapidly increasing, resulting in low antibiotic effectiveness even treating common infections. The presence of resistant pathogens in environments such as a hospital Intensive Care Unit (ICU) exacerbates the critical admission-acquired infections. This work focuses on the prediction of antibiotic resistance in Pseudomonas aeruginosa nosocomial infections at the ICU, using Long Short-Term Memory (LSTM) artificial neural networks as the predictive method.

Patients with cancer have a higher risk of severe bacterial infections. This study aims to determine the frequency, susceptibility profiles, and resistance genes of bacterial species involved in bacteremia, as well as risk factors associated with mortality in cancer patients in Colombia. In this prospective multicenter cohort study of adult patients with cancer and bacteremia, susceptibility testing was performed and selected resistance genes were identified.

The goal of this study was to explore the attitudes of people who inject drugs (PWID) and carry out risky practices, identifying underlying factors in their speech that sustain those attitudes. We proposed a qualitative research design with PWID focus groups (n = 34) and interviews with experts (n = 3). The interviews were recorded, transcribed, and analyzed following the principles of grounded theory and thematic analysis methodology.

  • Microalgae wastewater treatment can produce valuable products, especially through cyanobacteria that accumulate polyhydroxybutyrates (PHBs) for bioplastics.
  • Proper monitoring and culture conditions are crucial for PHB production, which poses challenges for existing technologies.
  • This study utilized hyperspectral technology and machine learning to monitor cyanobacteria growth and PHB production, defining three key indicators for effective tracking of this process.

This study aimed to explore dietary replacement soybean meal (SBM) with local pea seeds (PS-L) and the effects of surgically castrated (CM) or immunocastration (IM) in heavy male pigs, on growth performance, feeding behaviour, and tail and ear lesions. Four treatments were arranged factorially (2 × 2), with two sexes and two dietary treatments (96 pigs in eight pens). The inclusion of PS-L was 25%, 30%, and 40% during three phases (40−80 kg, 80−110 kg, and 110−140 kg, respectively).
