Cardiovascular disease is the leading cause of morbidity and mortality in maintenance hemodialysis (MHD) patients. The Transonic (TRS; Transonic Systems, Ithaca, NY) device is frequently used for determination of cardiac output (CO) by an indicator dilution technique. The Task Force Monitor (TFM; CN Systems, Graz, Austria) has gained attention as noninvasive tool for continuous beat-to-beat assessment of cardiovascular variables, including CO by impedance cardiography. Despite its use in cardiology and intensive care settings, the TFM has yet not been validated in dialysis patients. This study compares CO measurements in 12 MHD patients by TFM and TRS. Bland-Altman and regression analysis were used. CO was measured simultaneously by TRS and TFM. Average CO was 5.4 L/min by TRS and 5.0 L/min by TFM, respectively. Bland-Altman analysis revealed no significant systematic differences between the two methods (mean difference: 0.4 L/min; SD: 0.6; p > 0.05). Linear regression analysis showed significant correlation between both techniques (r = 0.802, p = 0.002). The SD of mean individual CO values was 1.1 L/min with TRS and 0.8 L/min with TFM, respectively.CO measured by TFM and TRS does not differ significantly, thus making the TFM an attractive noninvasive tool for the continuous beat-to-beat assessment of CO in MHD patients.

A new and non-invasive technology of left ventricular pressure-strain loop (LV-PSL) has recently been used to provide information on myocardial work (MW) and identify subtle modifications in cardiac function. This study aimed to use LV-PSL for early identification of changes in LV structure and MW in patients with end-stage renal disease (ESRD). Methods： Seventy-two patients with ESRD were divided into two groups based on undergoing maintenance hemodialysis (MHD), namely the dialysis group (ESRD-D group) and non-dialysis group (ESRD-ND group).

Purpose: Breast cancer radiation therapy (RT) techniques have historically delivered mean heart doses (MHDs) in the range of 5 Gy, which have been found to predispose patients to cardiopulmonary toxicities. The purpose of this study was to apply artificial intelligence (AI) cardiac substructure auto-segmentation to evaluate the corresponding substructure doses, whether there are laterality- and technique-specific differences in these doses, and if the doses are significantly associated with cardiorespiratory fitness after state-of-the-art RT planning and delivery for breast cancer.
Methods And Materials: Cardiopulmonary substructures were AI auto-segmented.
Objectives: Comorbidity prediction models have been demonstrated to offer more comprehensive and accurate predictions of death risk compared to single indices. However, their application in China has been limited, particularly among maintenance hemodialysis (MHD) patients. Therefore, the objective of this study was to evaluate the utility of comorbidity index models in predicting mortality risk among Chinese MHD patients.

Objective: To evaluate the effectiveness and safety of artificial intermittent infusion hemodiafiltration (I-HDF) in maintenance hemodialysis (MHD) patients with intradialytic hypotension (IDH), and to determine the optimal infusion dosage.
Methods: This single-center, prospective, self-controlled study included 30 MHD patients with IDH, treated from December 2022 to July 2023. Patients underwent three sessions of I-HDF as treatment group and conventional hemodialysis as control group.

Background: Patients with end-stage renal disease (ESRD) have increased insulin resistance (IR). The triglyceride glucose (TyG) index is a marker of IR and is associated with the prognosis of patients on maintenance hemodialysis (MHD). The aim of this study was to examine the relationship between the TyG index and the risk of death in patients on MHD.
