Intestinal mucins play a crucial role in the mucosal barrier, serving as the body's initial defense against microorganisms. However, how the host regulates the secretion and glycosylation of these mucins in response to bacterial invasion remains unclear. Our study demonstrates that when exposed to (), a gut pathobiont, the host mucosa promptly adjusts the behavior of specialized goblet cells (GCs) located in the middle of the crypts.

Article Synopsis
  • Cancer-related fatigue (CRF) is a prevalent symptom among individuals with primary brain tumors, but previous studies have largely relied on quantitative data, missing the depth of personal experiences.
  • The research involved semi-structured interviews with patients, caregivers, and healthcare professionals, uncovering four key themes: the widespread nature of CRF, its significant impacts, the support provided, and self-management practices by patients.
  • Findings reveal a profound lack of targeted information and resources for managing CRF in brain tumor patients, emphasizing the urgent need for specialized support and interventions.

Influenza viruses cause substantial morbidity and mortality every year despite seasonal vaccination. mRNA-based vaccines have the potential to elicit more protective immune responses, but for maximal breadth and durability, it is desirable to deliver both the viral hemagglutinin and neuraminidase glycoproteins. Delivering multiple antigens individually, however, complicates manufacturing and increases cost, thus it would be beneficial to express both proteins from a single mRNA.

Seasonal influenza vaccines provide mostly strain-specific protection due to the elicitation of antibody responses focused on evolutionarily plastic antigenic sites in the hemagglutinin head domain. To direct the humoral response toward more conserved epitopes, we generated an influenza virus particle where the full-length hemagglutinin protein was replaced with a membrane-anchored, "headless" variant while retaining the normal complement of other viral structural proteins such as the neuraminidase as well as viral RNAs. We found that a single administration of a headless virus particle-based vaccine elicited high titers of antibodies that recognized more conserved epitopes on the major viral glycoproteins.

Background: In 2017, the Canadian Partnership Against Cancer, a Canadian federally sponsored organisation, initiated a national multijurisdictional quality improvement (QI) initiative to maximise the use of synoptic data to drive cancer system improvements, known as the Evidence for Surgical Synoptic Quality Improvement Programme. The goal of our study was to evaluate the outcomes, determinants and learning of this nationally led initiative across six jurisdictions in Canada, integrating a mix of cancer surgery disease sites and clinicians.

Methods: A mixed-methods evaluation (surveys, semistructured interviews and focus groups) of this initiative was focused on the ability of each jurisdiction to use synoptic reporting data to successfully implement and sustain QI projects to beyond the completion of the initiative and the lessons learnt in the process.

Asteroids with diameters less than about 5 km have complex histories because they are small enough for radiative torques (that is, YORP, short for the Yarkovsky-O'Keefe-Radzievskii-Paddack effect) to be a notable factor in their evolution. (152830) Dinkinesh is a small asteroid orbiting the Sun near the inner edge of the main asteroid belt with a heliocentric semimajor axis of 2.19 AU; its S-type spectrum is typical of bodies in this part of the main belt.

Background: We aimed to define levels of unmet supportive care needs in people with primary brain tumor and to reach expert consensus on feasibility of addressing patients' needs in clinical practice.

Methods: We conducted secondary analysis of a prospective cohort study of people diagnosed with high-grade glioma (n = 116) who completed the Supportive Care Needs Survey-Short Form during adjuvant chemoradiation therapy. Participants were allocated to 1 of 3 categories: no need ("no need" for help on all items), low need ("low need" for help on at least 1 item, but no "moderate" or "high" need), or moderate/high need (at least 1 "moderate" or "high" need indicated).

Ionizing radiation has become widely used in medicine, with application in diagnostic techniques, such as computed tomography (CT) and radiation therapy (RT), where X-rays are used to diagnose and treat tumors. The X-rays used in CT and, in particular, in RT can have harmful side effects; hence, an accurate determination of the delivered radiation dose is of utmost importance to minimize any damage to healthy tissues. For this, medical specialists mostly rely on theoretical predictions of the delivered dose or external measurements of the dose.

Multiple wavelength phase shifting interferometry is widely used to extend the unambiguous range (UR) beyond that of a single wavelength. Towards this end, many algorithms have been developed to calculate the optical path difference (OPD) from the phase measurements of multiple wavelengths. These algorithms fail when phase error exceeds a specific threshold.

Despite the well-documented safety concerns and effect on quality of life, there does not yet exist a wide-reaching framework that links the etiologies of swallowing disorders to the potential short- and long-term outcomes in the context of International Classification of Functioning, Disability and Health (ICF). This paper introduces an expert-reviewed conceptual framework to highlight common etiologies of dysphagia as well as integrate immediate outcomes of dysphagia with long-term outcomes of dysphagia in terms of medical problems, health-related quality of life, functional effect, and psychosocial features. It also outlines the potential cyclical nature of long-term dysphagia outcomes perpetuating the original dysphagia.

Article Synopsis
  • Staphylococcus aureus is a bacteria that often causes lung infections, especially in people with chronic conditions.
  • Scientists found that this bacteria can use a substance called sialic acid to grow better, especially when it doesn’t work well with its signaling system (quorum sensing).
  • In patients with cystic fibrosis, researchers discovered that S. aureus often lives alongside bacteria that produce sialic acid, suggesting that sialic acid helps it become more harmful and survive longer in the lungs.
