Aim: This study aimed to analyze the predictive, prognostic and diagnostic value of autoantibodies to coagulation factor II thrombin receptor (F2R; protease-activated receptor 1, PAR1) (PAR1-AB) in patients with primary epithelial ovarian cancer (EOC).
Materials And Methods: A total of 197 patients with primary EOC and 200 healthy female blood donors were included in the study. Enzyme-linked immunosorbent assay was applied to determine PAR1-AB levels in blood sera taken preoperatively. Correlation of PAR1-AB with clinicopathological outcome, progression-free (PFS) and overall (OS) survival was analyzed and patients were compared with controls.
Results: PAR1-AB was significantly negatively correlated with histological grading (p=0.008) and was significantly lower in the patient group compared to healthy controls (p<0.001). There was no significant correlation of PAR1-AB level with PFS or OS.
Conclusion: This study showed PAR1-AB to significantly decrease in patients with primary EOC and with histological high-grade carcinoma. The relevance of PAR1-AB in early detection of ovarian cancer and follow-up for EOC should be further investigated.

Pharmacist-Directed Transition of Care Services Decrease Readmissions at a Safety-Net Hospital.
Ann Pharmacother
January 2025
Hennepin Healthcare, Minneapolis, MN, USA.
Background: Limited data exist describing the influence of pharmacist-led transition of care (TOC) services in safety-net hospital settings.
Objective: This analysis assessed the impact of pharmacist-led TOC services on hospital readmissions in a high-risk managed Medicaid population impacted by housing instability, substance use disorder (SUD), and mental health issues.
Methods: A retrospective evaluation of patients who received safety-net hospital-based TOC pharmacy services between January 1, 2022, and December 31, 2022, was conducted.
A randomized control trial to compare Quiet Eye training efficacy to traditional technical training with undergraduate student nurses' peripheral intravenous cannulation performance: a protocol.

Introduction: Peripheral intravenous cannulation (PIVC) is a common and complex procedure with low first-attempt success rates, causing patient suffering and increased healthcare costs. Quiet Eye (QE) training, a gaze-focused approach, has shown promise in improving procedural PIVC skills. We will examine the effectiveness of traditional technical training (TT) and QE training (QET) on student nurse PIVC performance.

Nephrology Center and Department of Rheumatology, Toranomon Hospital, Tokyo, Japan.
Objectives: To evaluate the efficacy and safety of first-line targeted synthetic disease-modifying anti-rheumatic drugs (tsDMARDs) in patients with rheumatoid arthritis (RA) and chronic kidney disease (CKD).
Methods: This retrospective cohort study included 216 patients with RA prescribed their first tsDMARDs at two hospitals between 2013 and 2022. Dose reduction and contraindication guidelines for tsDMARDs according to kidney function were followed.
Predictive value of insulin resistance metabolic score for cardiovascular disease in Chinese arthritis patients: a prospective cohort study.
Rheumatology (Oxford)
January 2025
Department of Gerontology, CR & WISCO General Hospital, Wuhan University of Science and Technology, Wuhan, Hubei, China.
Objectives: Although patients with arthritis have significantly increased cardiovascular disease (CVD) risk, effective prediction tools remain limited. This study aimed to evaluate the predictive value of the Metabolic Score for Insulin Resistance (METS-IR) for CVD events among Chinese patients with arthritis.
Methods: Using data from the China Health and Retirement Longitudinal Study (CHARLS), we conducted a 7-year prospective cohort study (2011-2018) involving 1,059 patients with arthritis.
The optimal annual case volume for acute type A aortic dissection surgery in relation to long-term outcomes.
Eur J Cardiothorac Surg
January 2025
Department of Cardiothoracic Surgery, Maastricht University Medical Centre (MUMC+), Netherlands.
Objectives: Previous analyses of the volume-outcome relationship have focused on short-term outcomes such as early mortality. The current study aims to update a novel statistical methodology, facilitating the evaluation of the relation between procedural volume and time-to-event outcomes such as long-term survival, using surgery for acute type A aortic dissection as an illustrative example.
Methods: This study employed an existing dataset of type A dissection outcomes, retrieved from literature.
