Low regulatory T-cells frequency is associated with graft rejection after small bowel transplantation: Clinical and experimental evidence.

Background: Intestinal transplantation (ITx) represents the only curative option for patients with irreversible intestinal failure. Nevertheless, its rejection rate surpasses that of other solid organ transplants due to the heightened immunological load of the gut. Regulatory T-cells (Tregs) are key players in the induction and maintenance of peripheral tolerance, suggesting their potential involvement in modulating host vs.

Effect of a Health Education Intervention to Reduce Fear of Falling and Falls in Older People: A Cluster Randomized Clinical Trial Protocol.

Fear of falling (FOF) and falls are prevalent issues among older adults, leading to activity restriction, decreased quality of life, and increased dependency. This study aims to assess the effectiveness of a nurse-led health education intervention to reduce FOF and fall incidence in older adults within primary care settings. This two-arm, multicenter, parallel, cluster-randomized clinical trial includes ten primary care centers in Spain and will enroll 150 adults over 65 years with FOF, mild or no functional dependence, and independent ambulation.

PRAME Immunostaining in BAP-1-Inactivated Melanocytic Tumors: Unraveling Diagnostic Complexity and Exploring Germline Mutation Associations.

Background: Cutaneous melanocytic tumors with BAP-1 inactivation (BIMTs), linked to mutations in the BAP-1 gene, present diagnostic challenges due to their morphological similarities with other melanocytic lesions. The search for reliable diagnostic markers, including PRAME, holds potential to significantly improve the accuracy of differential diagnoses.

Methods: A retrospective analysis of 32 BIMTs from 25 patients, collected between 2018 and 2022, involved histologic examination and immunostaining for BAP-1 and PRAME.

Association of Cutaneous Immune-related Adverse Events with Overall Survival and Progression-free Survival in Oncology Patients Receiving Immune Checkpoint Inhibitors: A Prospective Study of 189 Patients in a Spanish Tertiary Care Hospital.

Cutaneous immune-related adverse events (cirAEs) may be associated with tumoral response and survival in patients using immune checkpoint inhibitors, but this relationship remains unclear because previous reports on the topic have various limitations. The purpose of this study was to examine the association of cirAEs with overall survival and progression-free survival in patients starting immune checkpoint inhibitors. A prospective observational study was conducted in a Spanish tertiary care hospital, including participants between March 2020 and May 2022.

Effect of hydrophobic proteins in modulating the mechanical properties of lung surfactant membranes.

Pulmonary surfactant is a membranous complex that enables breathing dynamics at the respiratory surface. Extremely low values of surface tension are achieved at end-expiration thanks to a unique mixture of lipids and proteins. In particular, the hydrophobic surfactant proteins, specially the protein SP-B, are crucial for surfactant biophysical function, in order to provide the surfactant lipid matrix with the ability to form membranous multi-layered interfacial films that sustain optimal mechanical properties.
