Induction of intercrypt goblet cells upon bacterial infection: a promising therapeutic target to restore the mucosal barrier.

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.

Understanding and Addressing Prostate Cancer Disparities in Diagnosis, Treatment, and Outcomes Among Black Men.

Despite advances in screening, diagnosis, and treatment for prostate cancer (PCa), Black men tend to be diagnosed at younger ages, have higher mortality rates, and are at increased risk of recurrence or metastasis compared to their White counterparts. PCa disparities among Black men are caused by a complex interaction of social, behavioral, and biological factors across the public policy, community, organizational, interpersonal, and individual levels. Key contributing factors include mistrust in the health care system, poor communication between patients and providers, low awareness of screening guidelines, and high medical costs.

Solution and solubility of H atoms at the W/Cu interface.

Metallic interfaces are locations where hydrogen (H) is expected to segregate and lead to the formation and stabilization of defects. This work focuses on the tungsten/copper (W/Cu) interface built according to theWbcc(001)/Cuhcp(112-0)orientation. H behavior is subsequently determined at the interface and in its vicinity with electronic structure calculations based on the density functional theory (DFT).

Analytical interference in CA 19-9 immunoassay generates false-positive results in a young woman with a low-grade appendiceal tumor: An educational case report and brief literature review.

CA 19-9 (carbohydrate antigen 19-9) is a tumor marker widely used for the follow-up of patients with pancreatic cancer and other digestive neoplasia. This case report describes a discrepancy between the results of serum CA 19-9 analyses using the Alinity analytical platform (Abbott™) and two other techniques, Kryptor Gold (ThermoFisher Scientific™) and Cobas E411 (Roche™), in the context of a young woman with appendiceal mucocele. In this context, when the serum concentration of CA 19-9 is high, it may raise concerns about potential malignancy or rupture of the mucocele that may lead to tumoral dissemination in the abdominal cavity.

Assistive products in pharmacy practice to optimize medications use for visually impaired patients: Focus groups to explore community pharmacists' opinions and expectations.

Background: Visual impairment can significantly affect a person's ability to take medications safely. Therefore, pharmacists need to ensure safe and effective access to medication information, particularly through the use of assistive products, which are devices that compensate for partial or total vision loss. Although assistive products are used by visually impaired patients for activities of daily living, their use in medication management needs to be more widespread.

Infectious risks associated with outdoor sports activities.

In France, outdoor sports and activities account for 36% of sports engagement, making outdoor venues the most popular settings for sports participation. Discussing the links between sports and health almost always highlights the beneficial impact of engaging in sports. However, due to a lack of specific notifications, infectious risks are not subject to epidemiological monitoring, and need to be better understood.

Circulating Biomarkers Predictive of Treatment Response in Patients with Hormone-sensitive or Castration-resistant Metastatic Prostate Cancer: A Systematic Review.

Background And Objective: Metastatic prostate cancer (mPCa) harbors genomic alterations that may predict targeted therapy efficacy. These alterations can be identified not only in tissue but also directly in biologic fluids (ie, liquid biopsies), mainly blood. Liquid biopsies may represent a safer and less invasive alternative for monitoring patients treated for mPCa.

EZ-SPOTs: A simple and robust high-throughput liquid handling platform.

Liquid handling is a fundamental capability for many scientific experiments. Previously, we introduced the Surface Patterned Omniphobic Tiles (SPOTs) platform, which enables manipulation of hundreds to thousands of independent experiments without costly equipment or excessive consumable expenses. However, the SPOTs platform requires a custom coating formulation and lacks robustness.

Situations of anomie and the health workforce crisis: Policy implications of a socially sensitive and inclusive approach to human resources.

Health systems in most jurisdictions are facing an unprecedented workforce crisis, manifesting as labour shortages, high staff turnover, and increasing rates of absenteeism and burnout. These issues affect professional and occupational groups in both health and social care and individuals at early and later stages of their career. The intensity and pervasiveness of the crisis suggests that it is a multicausal phenomenon.

Next-Generation-Sequencing on fine needle aspirates in neck recurrence of thyroid cancers.

Objectives: Tumor molecular genotyping plays a key role in improving the management of advanced thyroid cancers. Molecular tests are classically performed on Formalin-Fixed Paraffin-Embedded (FFPE) carcinoma tissue. However alternative molecular testing strategies are needed when FFPE tumoral tissue is unavailable.

Evolutionary dynamics of glucose-deprived cancer cells: insights from experimentally informed mathematical modelling.

Glucose is a primary energy source for cancer cells. Several lines of evidence support the idea that monocarboxylate transporters, such as MCT1, elicit metabolic reprogramming of cancer cells in glucose-poor environments, allowing them to re-use lactate, a by-product of glucose metabolism, as an alternative energy source with serious consequences for disease progression. We employ a synergistic experimental and mathematical modelling approach to explore the evolutionary processes at the root of cancer cell adaptation to glucose deprivation, with particular focus on the mechanisms underlying the increase in MCT1 expression observed in glucose-deprived aggressive cancer cells.

Implementation of the Acute Care for Elders Strategy to Improve the Quality of Care Transitions in Quebec and Ontario: a Retrospective Multiple Case Study.

Background: In 2016, two Canadian hospitals participated in a quality improvement (QI) program, the International Acute Care for Elders (ACE) Collaborative, and sought to adapt and implement a transition coach intervention (TCI). Both hospitals were challenged to provide optimal continuity of care for an increasing number of older adults. The two hospitals received initial funding, coaching, educational materials, and tools to adapt the TCI to their local contexts, but the QI project teams achieved different results.

The Wood equation allows consistent fitting of individual antibody-response profiles of Zika virus or SARS-CoV-2 infected patients.

Antibody kinetic curves obtained during a viral infection are often fitted using aggregated patient data, hiding the heterogeneity of individual humoral immune responses. Individual antibody responses can be modeled using the Wood equation and grouped according to their profile. Such modeling takes into account several important kinetic parameters, such as the day when antibody detection becomes positive [daypos], the day of the maximal response [daymax], the maximum antibody level [levelmax], and the day when antibody detection becomes negative [dayneg].

A New and Rapid HPLC Method to Determine the Degree of Deacetylation of Glutaraldehyde-Cross-Linked Chitosan.

Chitosan is a linear biopolymer composed of D-glucosamine and N-acetylglucosamine units. The percentage of D-glucosamine in the polymeric chain can vary from one sample to another and is expressed as the degree of deacetylation (DDA). Since this parameter has an impact on many properties, its determination is often critical, and potentiometric titration is a common analytical technique to measure the DDA.
