  • The MONALEESA-7 study is the only phase 3 research on CDK 4-6 inhibitors for premenopausal patients with hormone receptor-positive, HER2 negative metastatic breast cancer, but there is limited data on palbociclib's effectiveness.
  • Our multicenter, retrospective study included 319 patients to evaluate the effectiveness of palbociclib and ribociclib in first-line treatment and how dose reduction due to neutropenia affects progression-free survival (PFS).
  • Results showed similar median PFS for both drugs (26.83 months for palbociclib and 29.86 months for ribociclib) and no significant impact of dose reduction on effectiveness, with P

Methods: A retrospective analysis was conducted on 75 lesions in 50 patients with pathologically proven breast cancer who underwent MRI in prone and supine positions between December 2019 and December 2020. The transverse, anteroposterior, and craniocaudal dimensions (in millimeters) of the tumor in the x -, y -, and z -axes were measured.

Department of Ophthalmologist, University of Health Sciences, Goztepe Research and Education Hospital, Istanbul, Turkey.

This study aims to evaluate the content and quality of popular videos about blepharoplasty treatment in YouTube. Four keywords "blepharoplasty," "upper blepharoplasty," "lower blepharoplasty," and "blepharoplasty information" were searched in YouTube. After the videos were sorted by the number of views, the last 50 videos were based on general characteristics, primary purpose, information content, relevance, audiovisual quality, as well as viewer interaction index DISCERN score (minimum-maximum: 16-75), (JAMA) score (minimum-maximum: 0-4), and Global Quality score (minimum-maximum: 0-5), and view rate formulas were calculated for each video.

We have some criticism regarding some technical issues. Mixed models have begun to play a pivotal role in statistical analyses and offer many advantages over more conventional analyses regarding repeated variance analyses. First, they allow to avoid conducting multiple -tests; second, they can accommodate for within-patient correlation; third, they allow to incorporate not only a random coefficient, but also a random slope, typically 'linear' time in longitudinal case series when there are enough data and patients' trajectories vary a lot and improving model fit.
