Exploring immune response toward transplanted human kidney tissues assembled from organoid building blocks.

The increasing scarcity of organs and the significant morbidity linked to dialysis require the development of engineered kidney tissues from human-induced pluripotent stem cells. Integrative approaches that synergize scalable kidney organoid differentiation, tissue biomanufacturing, and comprehensive assessment of their immune response and host integration are essential to accomplish this. Here, we create engineered human kidney tissues composed of organoid building blocks (OBBs) and transplant them into mice reconstituted with allogeneic human immune cells.

Efficacy of subthalamic deep brain stimulation programming strategies for gait disorders in Parkinson's disease: a systematic review and meta-analysis.

Patients with advanced Parkinson's disease often suffer from severe gait and balance problems, impacting quality of live and persisting despite optimization of standard therapies. The aim of this review was to systematically review the efficacy of STN-DBS programming techniques in alleviating gait disturbances in patients with advanced PD. Searches were conducted in PubMed, Embase, and Lilacs databases, covering studies published until May 2024.

Safety and Efficacy of a Preemptive Mycophenolate Mofetil Dose Reduction Strategy in Kidney Transplant Recipients.

Background: There are no high-quality data to guide long-term mycophenolate mofetil (MMF) dosing in kidney transplant recipients (KTRs) to balance the long-term risks of allograft rejection with that of infections and malignancy. At our center, KTRs are managed with either a "preemptive" dose reduction strategy, where the MMF dose is reduced after the first year before the development of adverse events, or with a "reactive" dosing strategy, where they are maintained on the same MMF dose and only reduced if they develop an adverse event. We hypothesized that a preemptive MMF dosing strategy after the first year of transplantation is associated with decreased infections without increasing alloimmune complications.

The value of pre-transplant coronary angiography findings in kidney transplant candidates at high risk for cardiovascular disease.

Introduction: Cardiovascular disease is a significant cause of mortality after kidney transplantation. Whether pre-transplant screening for coronary artery disease (CAD) in asymptomatic kidney transplant candidates (KTCs) is beneficial is unclear.

Methods: We conducted a retrospective cohort study evaluating post-transplant cardiovascular events in 192 high-risk KTCs who underwent pre-transplant CAD evaluation.

Primary central nervous system lymphoma: Imaging features and differential diagnosis.

Primary central nervous system lymphoma (PCNSL) represents 5% of malignant primary brain tumors. The clinical presentation typically includes focal neurological symptoms, increased intracranial pressure, seizures, and psychiatric symptoms. Although histological examination remains the gold standard for diagnostic confirmation, non-invasive imaging plays a crucial role for the diagnosis.
