Obesity is associated with the intestinal microbiota in humans but the underlying mechanisms are yet to be fully understood. Our previous phylogenetic study showed that the faecal microbiota profiles of nonobese versus obese and morbidly obese individuals differed. Here, we have extended this analysis with a characterization of the faecal metaproteome, in order to detect differences at a functional level. Proteins were extracted from crude faecal samples of 29 subjects, separated by 1D gel electrophoresis and characterized using RP LC-MS/MS. The peptide data were analyzed in database searches with two complementary algorithms, OMSSA and X!Tandem, to increase the number of identifications. Evolutionary genealogy of genes: nonsupervised orthologous groups (EggNOG) database searches resulted in the functional annotation of over 90% of the identified microbial and human proteins. Based on both bacterial and human proteins, a clear clustering of obese and nonobese samples was obtained that exceeded the phylogenetic separation in dimension. Moreover, integration of the metaproteomics and phylogenetic datasets revealed notably that the phylum Bacteroidetes was metabolically more active in the obese than nonobese subjects. Finally, significant correlations between clinical measurements and bacterial gene functions were identified. This study emphasizes the importance of integrating data of the host and microbiota to understand their interactions.

Chronic cerebral ischemia (CCI) is one of the most common forms of cerebrovascular disease, which affects a significant number of patients, often leading to disability, cognitive impairment and dementia. The analysis of modern data on the pathogenesis and risk factors for the development of CCI, as well as on the mechanisms of action of Mexidol on various links in the pathogenesis of CCI. A systematic search was conducted in the PubMed, MEDLINE and Google Scholar databases, on Russian and English-language sites with open access publications on the problem of CCI and on the drug Mexidol in the period from 2014 to 2024.

Children use nasogastric tubes (NGTs) to ensure optimum nutrition and medication delivery when oral feeding fails or when they experience faltering growth. Although this method is less invasive, children may experience complications associated with NGTs. There is a gap in the literature regarding the types and prevention of complications of NGTs in the pediatric population at home.

Background: Melasma, a common skin pigmentation disease, can negatively impact patients' mental health, social interactions, and physical appearance. Although we now have several treatments accessible, such as medicines, chemical peels, and phototherapy, which can help ease symptoms to some extent, the requirement for a long-term effective and safe treatment for patients is far from met. In the face of this problem, microneedling, as an innovative treatment, provides a new avenue for treating melasma.

Background: Delivery of health and care services using a combination of remote and/or in-person channels and digital and/or traditional tools (Hybrid Service Delivery, HSD) is increasingly seen as a way of improving quality and affordability, improving access, personalisation and sustainability, and reducing inequalities. Across the voluntary, community and social enterprise sector (VCSE), using a combination of remote and/or in-person channels and digital and/or traditional tools (HSD) has enabled the essential provision of services for people who have learning disabilities and/or autistic (LDA). However, it is unclear how different tools and channels have been used, what worked well or not well, for whom, and in what circumstances.
