Article Abstract
Background: Nutritional status is an important factor influencing toxicity of treatment. Nutritional assessment indicators such as the Prognostic Nutritional Index (PNI), Controlling Nutritional Status (CONUT) score and modified Glasgow Prognostic Score (mGPS) have been reported to be associated with treatment-related adverse events (AEs) for various malignancies. However, there are no reports investigating the relationship between nutritional status and AEs from poly-(ADP-ribose) polymerase (PARP) inhibitors (PARPi), which are widely used in recent years as maintenance therapy for ovarian cancer.
Objective: The primary objective was to investigate the usefulness of nutritional assessment indicators in predicting treatment discontinuation due to AEs from PARPi.
Methods: This multicenter retrospective study included patients diagnosed with ovarian cancer who received maintenance therapy with PARPi from January 2018 to December 2023. PNI, CONUT score, and mGPS were calculated based on hematological parameters measured within 7 days before the start of PARPi therapy.
Results: A total of 272 patients received maintenance therapy with PARPi during the period, but due to the absence of the blood collection of albumin levels within one week or other exclusion criteria, 71 patients were finally included in this analysis. AEs were seen in 59 patients (83.1%), including 25 (35.2%) severe events (grade ≥3 in Common Terminology Criteria for Adverse Events v5.0). Eighteen patients (25.4%) discontinued treatment due to PARPi-related AEs. Low PNI (<48.44) and high mGPS (≥1) were predictors of treatment discontinuation in both univariate and multivariate analyses. CONUT was not a significant predictor in this study.
Conclusions: Our study suggested that PNI and mGPS can predict the risk of treatment discontinuation due to PARPi-related AEs before starting maintenance therapy. This insight opens avenues for more personalized treatment plans, potentially improving patient outcomes.

Background: A clear understanding of minimal clinically important difference (MCID) and substantial clinical benefit (SCB) is essential for effectively implementing patient-reported outcome measurements (PROMs) as a performance measure for total knee arthroplasty (TKA). Since not achieving MCID and SCB may reflect suboptimal surgical benefit, the primary aim of this study was to use machine learning to predict patients who may not achieve the threshold-based outcomes (i.e.

This study aims to investigate the predictive value of combined phenotypic age and phenotypic age acceleration (PhenoAgeAccel) for benign prostatic hyperplasia (BPH) and develop a machine learning-based risk prediction model to inform precision prevention and clinical management strategies. The study analyzed data from 784 male participants in the US National Health and Nutrition Examination Survey (NHANES, 2001-2008). Phenotypic age was derived from chronological age and nine serum biomarkers.

Human skeletal muscle comprises slow-twitch (type I) and fast-twitch (type II) fibers. Fiber type-specific analyses often require manual isolation of fibers, necessitating effective tissue preservation. While freeze-drying remains the standard, alternative preservation methods such as RNAlater and RNAlater-ICE are increasingly used.

This study investigated the association between parameters derived from bioelectrical impedance spectroscopy (BIS) and arterial stiffness, as measured using carotid-femoral pulse wave velocity (cfPWV) and brachial-ankle pulse wave velocity (baPWV) pulse wave velocities. Data from 292 Japanese adults were analyzed. BIS was used to assess the phase angle (PhA), extracellular water to intracellular water ratio (ECW/ICW), and body cell mass-to-free fat mass ratio (BCM/FFM).

Background: The hemodynamic effects of femoro-femoral venoarterial (VA) extracorporeal membrane oxygenation (ECMO) on pulmonary capillary wedge pressure (PCWP) remain poorly defined. High ECMO flow is believed to increase PCWP and the risk of pulmonary edema; yet, supporting in vivo physiological data are lacking.
Objectives: The purpose of this study was to evaluate the impact of incremental femoro-femoral VA-ECMO flow variations on PCWP, hemodynamic, and echocardiographic parameters in patients with cardiogenic shock during the early phase of VA-ECMO support, after stabilization.
