Latent Profile Analysis and Influencing Factors of Learned Helplessness in Maintenance Hemodialysis Patients: A Cross-sectional Study.

Purpose: Maintenance hemodialysis (MHD) patients frequently experience psychological distress, including learned helplessness(LH), which impairs self-management and adversely affects health-related quality of life. This study aimed to investigate the latent profiles of LH among MHD patients and to identify the bio-psycho-social determinants influencing these profiles.

Method: A cross-sectional survey was conducted in five hospitals in Guangdong, China, from May to July 2024, enrolling 548 MHD patients.

The Effects of Oral Energy-Dense Supplements on Nutritional Status in Nondiabetic Maintenance Hemodialysis Patients: A Randomized Controlled Trial.

Background And Objectives: Fat-based energy-dense nutritional supplements may offer benefits over protein- or carbohydrate-dense supplements for patients receiving dialysis because of the adverse metabolic consequences of the latter. We conducted a randomized controlled trial to assess the effects of the short-term use of a fat-based nutritional supplement on various measures of nutritional status in patients receiving maintenance hemodialysis who have low dietary energy intake.

Design, Setting, Participants, & Measurements: We enrolled nondiabetic patients receiving hemodialysis for >3 months who had inadequate dietary energy intake (<30 kcal/kg per day).

[Effects of ultrapure water on the levels of oxidative stress and inflammation parameters in maintenance hemodialysis patients].

Objective: To evaluate the effects of ultrapure water on the levels of oxidative stress and inflammation parameters in maintenance hemodialysis patients.

Methods: Thirty-six stable maintenance hemodialysis patients were involved in this study, who were free of acute infection, vasculitis or disease activity and on hemodialysis therapy for at least 3 months before using ultrapure water. The parameters including serum advanced oxidation protein products (AOPP), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), myeloperoxidase (MPO), albumin (Alb), C-reactive protein (CRP), neopterin , tumor necrosis factor (TNF)-alpha, and interleukin (IL)-6 were measured before and 6, 12 months after use of ultrapure water, respectively.

[The protective effects to the function of kidney and long by clearing of cytokines in patients with open-heart surgery].

Objective: To observe the effect of cytokines absorption on renal and respiratory function in patients with open-heart surgery.

Methods: 30 patients undergoing valve replacement with cardiopulmonary bypass (CPB) were randomly divided into two groups. A sulfonated polyacrylonitrile hemofilter (AN69) that has been used to absorb cytokines was connected into the efferent limb of CPB in Group A (n = 15), and a cellulose triacetate hemofilter (CT 190G) instead of AN69 was used as controls (Group B, n = 15).

Effect of blood purification on plasma levels of intact parathyroid hormone in patients with chronic renal failure.

Objective: To study the effects of hemoperfusion and/or hemodialysis on plasma levels of intact parathyroid hormone (iPTH) in patients with chronic renal failure (CRF).

Methods: A total of 40 uremic patients were randomly divided into two groups to receive hemoperfusion in combination with hemodialysis (HP+HD) or exclusive hemodialysis (HD), respectively. Plasma iPTH concentration was measured by means of radio immunoassay.
