Translation of PET radiotracers for cancer imaging: recommendations from the National Cancer Imaging Translational Accelerator (NCITA) consensus meeting.

Background: The clinical translation of positron emission tomography (PET) radiotracers for cancer management presents complex challenges. We have developed consensus-based recommendations for preclinical and clinical assessment of novel and established radiotracers, applied to image different cancer types, to improve the standardisation of translational methodologies and accelerate clinical implementation.

Methods: A consensus process was developed using the RAND/UCLA Appropriateness Method (RAM) to gather insights from a multidisciplinary panel of 38 key stakeholders on the appropriateness of preclinical and clinical methodologies and stakeholder engagement for PET radiotracer translation.

Outcomes of pediatric patients with suspected allergies to COVID-19 vaccines.

Background: Adverse effects following immunizations (AEFIs) can contribute to vaccine hesitancy.

Objective: We evaluated clinical outcomes of AEFIs subsequent to administration of the coronavirus disease 2019 (COVID-19) vaccine at 2 pediatric allergy centers.

Methods: Data on pediatric patients referred for COVID-19 AEFI concerns between March 2021 and October 2022 were reviewed.

Tissue-resident memory CD8 T cell diversity is spatiotemporally imprinted.

Tissue-resident memory CD8 T (T) cells provide protection from infection at barrier sites. In the small intestine, T cells are found in at least two distinct subpopulations: one with higher expression of effector molecules and another with greater memory potential. However, the origins of this diversity remain unknown.

Hematopoietic stem cell transplantation as rescue therapy for refractory autoimmune retinopathy: a case report.

Autoimmune retinopathy (AIR) is a rare, potentially blinding retinal disease that remains a challenging condition to manage when resistant to conventional immune-modulatory approaches. We report clinical and electrophysiological improvement in a 49-year-old patient who underwent an autologous hematopoietic stem cell transplant (aHSCT) for thymoma-associated AIR after experiencing progressive disease despite receiving periocular and systemic steroids, mycophenolate mofetil, baricitinib, tacrolimus, bortezomib, rituximab, plasmapheresis, and intravenous immunoglobulin. The aHSCT had two stages: (i) peripheral blood stem cell harvest following mobilization with cyclophosphamide and granulocyte colony-stimulating factor, and (ii) conditioning regimen with plasmapheresis, rituximab, cyclophosphamide, and anti-thymocyte globulin high-dose therapy, followed by autologous hematopoietic cell infusion of 5.

Does Pelvic Congestion Cause Bladder Symptoms-Potential New Indication to Treat Pelvic Congestion.

Background: Pelvic Congestion Syndrome (PCS) is a condition characterised by chronic pelvic pain resulting from the dilation and reflux of veins within the pelvis. While pelvic pain is the primary symptom of PCS, other associated symptoms may vary among individuals. Bladder symptoms have been commonly observed in PCS, including increased urination frequency, urinary urgency, nocturia and rarely haematuria.
