Article Synopsis
  • The IMWG frailty index shows that frailty levels in patients undergoing anti-myeloma treatment can change frequently over time.
  • Assessing frailty dynamically during treatment provides better predictions for survival and early mortality than just looking at initial frailty levels.
  • The study references two clinical trials, HOVON 143 (NTR6297) and HOVON 123 (NTR4244), related to this research.

Objectives: To determine associations between the banning of sex work during the COVID-19 pandemic, and work, financial problems, mental well-being and HIV/sexually transmittable infection (STI) testing among sex workers in the Netherlands.

Design: Two cross-sectional online surveys. The first survey covered two time-periods: pre-COVID-19 (1 January 2019 to 31 December 2019) and period 1 (15 March 2020 to 1 July 2020).

We present a patient at risk of misdiagnosis with multiple myeloma due to pseudohypercalcemia. Examinations showed monoclonal protein, 50% monoclonal plasma cells in bone marrow, and hypercalcemia but no osteolytic bone lesions. Follow-up tests revealed pseudohypercalcemia, with elevated total calcium, but normal ionized calcium: a discrepancy due to calcium binding to monoclonal paraprotein (confirmed by laboratory experiments).

Background: Frailty in newly-diagnosed multiple myeloma (NDMM) patients is associated with treatment-related toxicity, which negatively affects health-related quality of life (HRQoL). Currently, data on changes in HRQoL of frail and intermediate-fit MM patients during active treatment and post-treatment follow-up are absent.

Methods: The HOVON123 study (NTR4244) was a phase II trial in which NDMM patients ≥ 75 years were treated with nine dose-adjusted cycles of Melphalan-Prednisone-Bortezomib (MPV).
