Environmental Control of Queuosine Levels in Streptococcus mutans tRNAs.

Queuosine (Q) is a modification of the wobble base in tRNAs that decode NA(C/U) codons. It is ubiquitous in bacteria, including many pathogens. Streptococcus mutans is an early colonizer of dental plaque biofilm and a key player in dental caries.

Phase II Trial of Nivolumab Plus Doxorubicin, Vinblastine, Dacarbazine as Frontline Therapy in Older Adults With Hodgkin Lymphoma.

Purpose: We conducted a phase I/II study evaluating nivolumab plus doxorubicin, vinblastine, dacarbazine (N-AVD) as frontline therapy for treatment-naïve older adults (OA) with classical Hodgkin lymphoma (cHL; ClinicalTrials.gov identifier: NCT03033914).

Methods: Patients age ≥60 years with newly diagnosed, any stage, cHL were treated with six cycles of AVD at standard doses plus nivolumab 240 mg intravenously once every 2 weeks (on days 1 and 15) of each cycle.

Comparison of Survivorship Care Guidelines for Patients With Lymphoma: Recommendations for Harmonization and Future Research Agenda.

Purpose: Lymphomas are a heterogeneous group of diseases that develop in individuals of all ages and have variable prognoses. Improved survival resulting from therapy advances has led to the emergence of diverse late effects. Although several (US)-based organizations have developed survivorship guidelines, the distinct features of lymphoma subtypes and diverse therapies used raise concerns regarding their applicability to lymphoma survivors.
