RESUMO
Exogenous human herpes virus 6 (HHV-6) reinfection has never been reported in patients receiving tumor-infiltrating T lymphocytes therapy. We report an unusual case of HHV-6 infection following infusion of HHV-6 infected autologous T lymphocytes. HHV-6 infection could interfere with the tumor antigen immune recognition and the efficacy of immunotherapy.

Quantification of behavior is critical in diverse applications from neuroscience, veterinary medicine to animal conservation. A common key step for behavioral analysis is first extracting relevant keypoints on animals, known as pose estimation. However, reliable inference of poses currently requires domain knowledge and manual labeling effort to build supervised models. We present SuperAnimal, a method to develop unified foundation models that can be used on over 45 species, without additional manual labels. These models show excellent performance across six pose estimation benchmarks. We demonstrate how to fine-tune the models (if needed) on differently labeled data and provide tooling for unsupervised video adaptation to boost performance and decrease jitter across frames. If fine-tuned, SuperAnimal models are 10-100× more data efficient than prior transfer-learning-based approaches. We illustrate the utility of our models in behavioral classification and kinematic analysis. Collectively, we present a data-efficient solution for animal pose estimation.

OBJECTIVES: The value of Epstein-Barr virus (EBV) biomarkers on the prognosis of HIV-related non-Hodgkin's lymphoma (NHL) has been poorly explored in the combined antiretroviral therapy (cART) era. DESIGN: We evaluated EBV DNA load and EBV antibodies in HIV-NHL patients enrolled in the French ANRS-CO16 Lymphovir Cohort between 2008 and 2015. METHODS: Whole blood and plasma EBV DNA load and serological profiles were analyzed in 76 HIV-infected patients at diagnosis of NHL and 6âmonths after the initiation of chemotherapy. RESULTS: Prechemotherapy whole blood (WB) and plasma EBV DNA loads were positive for 80 and 45% of HIV-NHL patients, respectively. Pretreatment WB EBV DNA positivity was associated with a positive plasma HIV-1 RNA load (relative risk (RR), 4.42 [1.33; 14.72]) and plasma EBV DNA positivity with EBV in situ detection (RR 10.62 [2.38; 47.49]). Following chemotherapy, the proportions of patients with positive WB or plasma EBV DNA declined from 81 to 23% (Pâ<â0.0001) and from 43 to 8% (Pâ<â0.0001), respectively. Estimated 2-year progression-free survival did not differ according to prechemotherapy WB positivity (82% versus 67%, Pâ=â0.15) or plasma EBV DNA positivity (76% versus 81%, Pâ =â0.52). CONCLUSIONS: The plasma EBV DNA load correlates with in situ EBV detection. The WB EBV DNA load correlates with HIV load. WB and plasma EBV DNA loads at NHL diagnosis do not constitute prognostic markers for HIV-NHL patients in the modern cART era.
