Inborn errors of immunity reveal molecular requirements for generation and maintenance of human CD4 IL-9-expressing cells.

Background: CD4 T cells play essential roles in adaptive immunity. Distinct CD4 T-cell subsets-T1, T2, T17, T22, T follicular helper, and regulatory T cells-have been identified, and their contributions to host defense and immune regulation are increasingly well defined. IL-9-producing T9 cells were first described in 2008 and appear to play both protective and pathogenic roles in human immunity.

Midterm survival, clinical, and hemodynamic outcomes of a novel mechanical mitral valve prosthesis.

Objective: To evaluate the midterm survival, clinical, and hemodynamic outcomes of the On-X mechanical mitral valve, based on the 5-year results of the Prospective Randomized On-X Anticoagulation Clinical Trial (PROACT).

Method: PROACT Mitral was a multicenter study evaluating 401 patients who underwent mitral valve replacement (MVR) with either Standard or Conform-X On-X mitral valves, comparing low-dose and standard-dose warfarin. Here we report prespecified secondary outcomes of survival, New York Heart Association (NYHA) functional classification, and valve hemodynamics as assessed by core lab-adjudicated echocardiography at 1, 3, and 5 years in the pooled population.

Management of Inferior vena cava injury in a resource limited setup: A rare case report.

Introduction And Importance: Traumatic injuries of the inferior Vena Cava (IVC) are rare among traumatic abdominal injuries. It accounts for fewer than 5 % of penetrating injuries and 0.5 % of blunt trauma injuries.

Flt3L enhances clonal diversification and selective expansion of intratumoral CD8 T cells while differentiating into effector-like cells.

PD-1 blockade enhances anti-tumoral CD8 T cell responses via type 1 conventional dendritic cells (cDC1s), but how cDC1s change the properties of intratumoral CD8 T cells remains to be determined. Here, we identified two populations of intratumoral CD8 T cells distinguished by their expression of asialo-ganglio-N-tetraosylceramide (asGM1). asGM1 and asGM1CD8 T cells show enriched expression of genes characteristic for precursor exhausted T (Tpex) cells and terminally exhausted T (Tex) cells, respectively.

Dietary Restriction Enhances CD8 T Cell Ketolysis to Limit Exhaustion and Boost Anti-Tumor Immunity.

Reducing calorie intake without malnutrition limits tumor progression but the underlying mechanisms are poorly understood. Here we show that dietary restriction (DR) suppresses tumor growth by enhancing CD8 T cell-mediated anti-tumor immunity. DR reshapes CD8 T cell differentiation within the tumor microenvironment (TME), promoting the development of effector T cell subsets while limiting the accumulation of exhausted T (Tex) cells, and synergizes with anti-PD1 immunotherapy to restrict tumor growth.

Transcatheter Aortic Valve Implantation Bailout for Severe Aortic Insufficiency due to Aortic Root Dissection Following Ascending Aortic Aneurysm Repair.

This novel case documents the successful use of transcatheter aortic valve implantation to treat severe aortic insufficiency arising from aortic root dissection following the repair of an ascending aortic aneurysm in a 75-year-old female patient. After she presented with symptoms of congestive heart failure, investigation revealed new severe aortic insufficiency and an acute aortic dissection. Given the prohibitive risks of reoperation, a self-expanding 27-mm Portico (St Jude Medical) prosthetic aortic valve was deployed, resulting in substantial clinical improvement without procedural complications.

Surgical Treatment of Brachiocephalic Artery Aneurysm With Impending Rupture and Tracheal Communication.

Brachiocephalic artery aneurysm is uncommon but may require surgery because it tends to enlarge, rupture, or cause symptoms related to thrombosis or compression. This case report describes a brachiocephalic artery aneurysm in a 72-year-old man who presented at the hospital with dyspnea and hemoptysis resulting from impending rupture and tracheal communication.

Enhancing Pancreatic Cancer Therapy with Targeted CD133-Exosome Delivery of PD-L1 siRNA: A Preclinical Investigation.

Objectives: This study assessed the anticancer potential of genetically modified exosomes engineered to express CD133-binding peptides on their surface and carry PD-L1 siRNA for the treatment of murine model of metastatic pancreatic cancer.

Methods: CD133-targeting exosomes (tEx) were generated by harvesting conditioned media from adipose-derived stem cells (ASCs) that had undergone transformation using pDisplay vectors encoding CD133-binding peptide sequences. Subsequently, siPD-L1-loaded CD133-targeting Exosomes, referred to as tEx(s), were created by incorporating PD-L1 siRNA into the tEx using Exofect kit.

Use of Extracorporeal Membrane Oxygenation-Facilitated Large-Bore Catheter Embolectomy in the Treatment of Acute Pulmonary Embolism Complicated by Shock.

This article reports the case of a 42-year-old man who presented with a saddle pulmonary embolus complicated by normotensive cardiogenic shock. The patient was first stabilized with venoarterial extracorporeal membrane oxygenation. Then, while the patient was still on extracorporeal membrane oxygenation, thrombectomy with a large-bore catheter device was performed that resulted in a large decrease in pulmonary artery pressures and a clinically significant increase in cardiac index, with rapid clinical improvement.

ScRNA-Seq Analysis of Tongue Tissues in Chronic Hyperplastic Candidiasis.

Chronic hyperplastic candidiasis (CHC) is a rare but severe subtype of oral candidiasis distinguished by its potential malignant transformation and suboptimal response to antifungal therapies. However, the cells and mechanisms that play key roles in this process remain unclear. Therefore, we performed the first single-cell RNA sequencing (scRNA-seq) analysis of CHC-affected tongue tissues to reveal the microenvironmental changes and immunological etiology of CHC.

A Comprehensive Review of Atrial Infarction.

Atrial infarction is often undiagnosed in patients with underlying ischemic heart disease and is identified only later, upon autopsy. One of the main challenges in diagnosing the condition is its localization within the affected atria. Treatment of atrial infarction focuses on acute reperfusion therapy, long-term management of cardiovascular disease risk factors, consideration of antiarrhythmia medications, and anticoagulation therapy.

The use and implementation of omalizumab as food allergy treatment: Consensus-based guidance and Work Group Report of the Adverse Reactions to Foods Committee of the American Academy of Allergy, Asthma & Immunology.

Omalizumab was recently approved by the US Food and Drug Administration for treatment of any single food allergy or multiple food allergies in children aged 1 year and older and adults. There is currently no formal guidance regarding recommended best practices for omalizumab use in food allergy, including patient selection, anticipated goals and outcomes of therapy, procedure for monitoring patients who elect to start omalizumab therapy, and ways in which omalizumab can be incorporated into the landscape of food allergy management and daily clinical practice. This work group report was developed by the food allergy therapies subcommittee of the Adverse Reactions to Foods Committee within the American Academy of Allergy, Asthma & Immunology.

Assessment of virtual bracket removal by artificial intelligence and thermoplastic retainer fit.

Introduction: Digital orthodontics is here to make our specialty more efficient, and the integration of artificial intelligence (AI) is no exception. This study aimed to compare the accuracy of a workflow involving virtual bracket removal (VBR) by AI to traditional bracket removal. A secondary objective was to compare the clinical fit of thermoplastic orthodontic retainers fabricated from 3-dimensional (3D) printed models created by each method.

SeptAsTERS- SeptiCyte® RAPID as assessment tool for early recognition of sepsis - a prospective observational study.
