Background: Medial meniscal repair performed at the time of primary anterior cruciate ligament reconstruction (ACLR) has been shown to be significantly associated with subsequent surgery, and subsequent surgery has been associated with increased Knee injury and Osteoarthritis Outcome Score (KOOS) pain score and decreased patient satisfaction.

Hypothesis/purpose: The purpose was to determine if medial meniscal repair decreases KOOS pain 10 years after ACLR and to assess the consequences of subsequent surgery on the development of KOOS pain. The authors hypothesized that medial meniscal repair performed at the time of primary ACLR decreases the likelihood of developing KOOS pain.

In modern clinical practice, less than half of patients with new-onset heart failure (HF) undergo ischemic evaluation and only a minority undergo revascularization. We aimed to assess the proportion of the effect of hypertension (antihypertensive treatment) on incident HF to be eliminated by prevention of coronary heart disease (CHD) event treated with or without revascularization, considering possible treatment-mediator interaction. The causal mediation analysis of Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) included 42,418 participants (age 66.

Article Synopsis
  • The study examines how reducing glycated hemoglobin (HbA1c) and body weight affects health outcomes in patients with type 2 diabetes (T2D) who are using different antidiabetic medications, including GLP-1 receptor agonists.
  • Researchers analyzed health records from a large patient sample at the Cleveland Clinic over a 20-year period to assess the impact of weight and HbA1c changes on conditions like heart failure, hypertension, and kidney disease.
  • Findings indicate that even small reductions in weight and HbA1c levels can significantly lower the risk of various health complications in T2D patients, highlighting the importance of these factors in diabetes management.*

Background: For patients with complicated type 1 diabetes having, for example, hypoglycemia unawareness and end-stage renal disease because of diabetic nephropathy, combined pancreas and kidney transplantation (PKT) is the therapy of choice. However, the shortage of available grafts and complex impact of risk factors call for individualized, impartial predictions of PKT and pancreas transplantation (PT) outcomes to support physicians in graft acceptance decisions.

Methods: Based on a large European cohort with 3060 PKT and PT performed between 2006 and 2021, the 3 primary patient outcomes time to patient mortality, pancreas graft loss, and kidney graft loss were visualized using Kaplan-Meier survival curves.
