Meta-Analysis: Exclusive Enteral Nutrition in Adults With Ulcerative Colitis.

Background: Exclusive enteral nutrition (EEN) is an established dietary therapy for Crohn's disease but its role in ulcerative colitis remains unclear.

Aims: To investigate the efficacy of EEN in adults with active ulcerative colitis and compare variations in treatment protocols, safety, tolerability and adherence.

Methods: We conducted a systematic search of MEDLINE, Embase, Cochrane CENTRAL, Emcare, CINAHL, Web of Science and trial registries for articles published from inception until July 21, 2024.

Enabling simultaneous photoluminescence spectroscopy and X-ray footprinting mass spectrometry to study protein conformation and interactions.

X-ray footprinting mass spectrometry (XFMS) is a structural biology method that uses broadband X-rays for hydroxyl radical labeling to map protein interactions and conformation in solution. However, while XFMS alone provides important structural information on biomolecules, as we move into the era of the interactome, hybrid methods are becoming increasingly necessary to gain a comprehensive understanding of protein complexes and interactions. Toward this end, we report the development of the first synergetic application of inline and real-time fluorescent spectroscopy at the Advanced Light Source's XFMS facility to study local protein interactions and global conformational changes simultaneously.

International consensus statement on microbiome testing in clinical practice.

There is growing interest in the potential exploitation of the gut microbiome as a diagnostic tool in medicine, but evidence supporting its clinical usefulness is scarce. An increasing number of commercial providers offer direct-to-consumer microbiome diagnostic tests without any consensus on their regulation or any proven value in clinical practice, which could result in considerable waste of individual and health-care resources and potential drawbacks in the clinical management of patients. We convened an international multidisciplinary expert panel to standardise best practices of microbiome testing for clinical implementation, including recommendations on general principles and minimum requirements for their provision, indications, pre-testing protocols, method of analyses, reporting of results, and potential clinical value.

Equity of access to pathological diagnosis and bronchoscopy for lung cancer in Aotearoa New Zealand.

Background: Māori are less likely to survive their lung cancer once diagnosed, but it remains unclear whether this is partially driven by poorer access to best-practice diagnostic services.

Methods: We examined all lung cancer registrations in Aotearoa New Zealand between 2007-2019 (n=27,869) linked to national administrative health datasets and further stratified by ethnicity, tumour type and stage of disease. Using descriptive and regression analyses, we compared ethnic groups in terms of the basis of diagnosis (e.
