Medial patellofemoral ligament reconstruction normalizes patellar kinematics but fails to predict cartilage contact area: A prospective 3D MRI study.

Introduction: The medial patellofemoral ligament (MPFL) is the main patellar stabilizer in low knee flexion degrees (0-30°). Isolated MPFL reconstruction (MPFLr) is therefore considered the gold standard of surgical procedures for low flexion patellofemoral instabilities (PFIs). Despite excellent clinical results, little is known about the effect of MPFLr on kinematic parameters (KPs) of the patellofemoral joint in vivo.

Activity of CDK4/6 inhibitors and parameters affecting survival in elderly patients in age-subgroups: Turkish Oncology Group (TOG) retrospective study.

Highly selective inhibitors of cyclin-dependent kinase 4 and 6 (CDK4/6is) have emerged as a standart of care for first- and second-line therapies in combination with endocrine therapy (ET) for HR+/HER2- metastatic breast cancer (MBC) patients. It has been reported that combination therapy is more effective than ET alone and is safe in elderly patients as well as young patients. Nevertheless, elderly and very old patients with HR+/HER2-MBC treated with CDK4/6 inhibitor (CDK4/6i) combinations are relatively underrepresented in randomized controlled trials.

Assessment of dyslipidemia management in Turkey using a Delphi panel.

This study evaluated the management of dyslipidemia in Turkey with the goal of understanding current diagnosis and treatment patterns, as well as identifying unmet needs in achieving effective low-density lipoprotein cholesterol (LDL-C) targets. Using a Delphi panel consisting of nine expert cardiologists, the study reveals key gaps in dyslipidemia management, particularly in the underutilization of combination therapies, such as statins and PCSK9 inhibitors, which are crucial for achieving LDL-C targets in high-risk patients. The findings indicate that while many patients with very high cardiovascular risk are diagnosed, a significant proportion do not receive optimal treatment to reach LDL-C levels recommended by European guidelines.
