Dose optimization strategy of the tyrosine kinase inhibitors imatinib, dasatinib, and nilotinib for chronic myeloid leukemia: From clinical trials to real-life settings

Frontiers in Oncology, 2023
With the advent of tyrosine kinase inhibitors (TKIs), the treatment prospects of chronic myeloid leukemia (CML) have changed markedly. This innovation can lengthen the long-term survival of patients suffering from CML. However, long-term exposure to TKIs

Steps towards implementation of protocolized dose reduction of adalimumab, etanercept and ustekinumab for psoriasis in daily practice

Journal of Dermatological Treatment, 2023
Background Dose reduction (DR) of adalimumab, etanercept and ustekinumab has proven to be (cost-)effective in psoriasis patients with low disease activity. Further implementation is needed to establish application of DR for eligible patients.

Dose reduction in xeroradiography of the breast [PDF]

American Journal of Roentgenology, 1977
In a study of the effects of beam filtration on the entrance exposures encountered in xeroradiography of the breast, it was found that increasing the total filtration to 3.2 mm of aluminum reduced entrance exposures by a factor of three compared to the xeroradiographic techniques without added filtration. Changes in the processing parameters were found

Potential for Dose Reduction in CT-Derived Left Ventricular Ejection Fraction: A Simulation Study

Tomography, 2023
Background: Measuring left ventricular ejection fraction (LVEF) is important for detecting heart failure, e.g., in treatment with potentially cardiotoxic chemotherapy. MRI is considered the reference standard for LVEF, but availability may be limited and
