Background/aims: Relative adrenal insufficiency (RAI) is frequent in patients with liver cirrhosis and affects their prognosis. Scarce data on RAI in patients with alcohol-associated hepatitis (AAH) exists. This study aimed to document the prevalence and prognostic implication of RAI in patients with severe AAH.

In this work, defatted BSG (DB) was subjected to an extraction process with subcritical water at different temperatures to obtain extracts rich in phenols and the cellulosic fractions, which were also purified by using hydrogen peroxide (HO). The results showed that the dry extracts obtained at 170 °C were richer in phenolics (24 mg Gallic Acid Equivalent (GAE) g DB), but with lower antioxidant capacity (71 mg DB·mg 2,2-diphenyl-1-pikryl-hydrazyl).

The Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome is an idiosyncratic drug-induced reaction that primarily affects the liver, lungs, and kidneys. While several organs are commonly involved, the incidence of DRESS affecting the gastrointestinal tract is rarely reported. We present a 72-year-old man with a history of epilepsy who developed DRESS syndrome manifested by eosinophilic pancolitis, cholestasis, and reactivation of cytomegalovirus (CMV) following the initiation of lamotrigine.

The use of greener methods for separating cellulose would contribute to better exploitation of this biomass. Subcritical water extraction (SWE) at 160 and 180 °C has been used as a previous treatment to purify cellulose of AS, followed by a bleaching step with hydrogen peroxide (8%) at pH 12.

Azithromycin has both antimicrobial and anti-inflammatory effects and has been effective in improving lung function in a variety of lung diseases. We investigated lung function trajectories among CWH with CLD on ART enrolled in a randomized controlled trial of adjuvant azithromycin.

These were characterized by their structural, mechanical, barrier, and optical properties, as well as the polymer crystallization, thermal stability, and component migration in different food simulants.

The retrogradation of the starch throughout storage (1, 5, and 10 weeks) gave rise to stiffer and less extensible monolayers with lower water vapour barrier capacity. In contrast, the PLA monolayers, with or without extract, did not show marked changes with storage.

Respirometric analyses and film disintegration kinetics were used to monitor the process over a period of 162 days.

PHAs have gained much attention from researchers and industry because of their biobased nature and appropriate features, similar to conventional synthetic plastics. This review aims to discuss some of the recent solutions to challenges associated with PHA production.

Objective: Objective of our study was to describe patterns of admission in children; before ART initiation, within the first six months, and post-six months of ART between 2001 and 2016.
Food preservation is a set of procedures and resources aimed at blocking the action of external and internal agents that may alter the original characteristics of food [...
View Article and Find Full Text PDFAlmond skin (AS) is an agro-industrial residue from almond processing that has a high potential for valorisation. In this study, subcritical water extraction (SWE) was applied at two temperatures (160 and 180 °C) to obtain phenolic-rich extracts (water-soluble fraction) and cellulose fibres (insoluble fraction) from AS. The extraction conditions affected the composition and properties of both valorised fractions.

The relationship between inflammatory markers and anti-inflammatory medication in PIMS-TS is unknown. We retrospectively investigated the relationship between demographics, biomarkers, treatment, and length of stay (LOS) in this novel disease.

Metastasis in breast cancer can occur as relapse of a treated primary tumour or at the time of diagnosis of the tumour. The aim of this review is to show if both metastasis are different molecular entities characterised by different miRNA signatures that could be studied as specific biomarkers for each entity.

The composition and properties of the CFs were significantly affected by the purification process. The USHT treatment was as efficient as the ALK at eliminating the silica content, but the fibres maintained a notable ratio of hemicellulose (∼16 %).

The assignment of fossils to extant clades has traditionally relied on morphological similarity and on apomorphies shared with extant taxa. The use of explicit phylogenetic analyses to establish fossil affinities has so far remained limited.

The films were obtained by thermoprocessing while the bilayers were obtained by thermocompression of the different monolayers (TPS-PLA, TPScf-PLA, TPS-PLAes and TPScf-PLAes). TPS conferred oxygen barrier capacity to the laminates, which was improved by the cf incorporation.

Methods: Participants were enrolled between 2016 and 2019, were aged 6-19 years, living with HIV, had chronic lung disease (FEV z-score < -1) and had taken antiretroviral therapy (ART) for at least six months. We used multivariate logistic regression to identify risk factors for virological non-suppression after 48 weeks, among participants who were non-suppressed at enrolment.
