AI Article Synopsis
- Hair elemental concentrations in hemodialysis (HD) patients were examined for their relationships with health-related quality of life (HRQOL) and nutrition.
- A study involving 60 male HD patients measured 26 elemental concentrations in scalp hair and assessed HRQOL using the Short Form 36 health survey, along with various nutritional indices.
- Key findings include positive correlations between phosphorus and zinc with factors like serum creatinine and HRQOL physical domains, while cadmium and toxic elements like iodine and selenium showed potential adverse effects on nutritional status and HRQOL.
Article Abstract
Elemental concentrations in hair from hemodialysis (HD) patients have not been well investigated. We examined the relationships between the elemental concentrations in scalp hair and health-related quality of life (HRQOL) and nutritional status in HD patients. Twenty six elemental concentrations were measured in scalp hair samples from 60 male HD patients using inductively-coupled plasma mass spectrometry. To evaluate HRQOL, the Short Form 36 item health survey (SF36) was used. As indices of nutritional status, body mass index, serum parameters, and geriatric nutritional risk index (GNRI) were used. Phosphorus correlated positively with serum creatinine, blood urea nitrogen (BUN), GNRI and the physical domains of the SF36. Zinc correlated positively with serum creatinine, BUN and the physical domains of the SF36. Mercury and arsenic correlated positively with BUN. Cadmium correlated negatively with serum albumin, BUN and GNRI. Copper correlated positively with the physical domains of the SF36. Iodine correlated negatively with the physical domains of the SF36. Selenium correlated negatively with the mental domains of the SF36. In conclusion, phosphorus and zinc concentrations in scalp hair can be additional biomarkers of HRQOL and/or nutritional status in HD patients. Cadmium accumulation correlated with malnutrition. Iodine and selenium accumulation may adversely affect HRQOL. Further investigation is necessary to determine precisely how these elements affect these measures.

December 2024
Center for Research and Innovation in Precision Medicine of Respiratory Diseases, "Victor Babes" University of Medicine and Pharmacy Timisoara, Eftimie Murgu Square 2, Timisoara 300041, Romania.
Pulmonary resections are critical interventions for treating various lung pathologies, both benign and malignant. Understanding the impact of these surgeries on patients' Quality of Life (QoL) is essential for optimizing care. This study aims to compare the Health-Related Quality of Life (HRQoL) and psychological well-being in patients who underwent pulmonary resections for benign versus malignant etiologies.

Due to a lack of validated methodologies, this study aimed to evaluate the quality of life (QoL) among individuals affected by lymphedema and to compare them with the general population and common diseases. Patients were recruited from October 2023 till March 2024. The SF-36 and LYMQOL questionnaires were administered.

Healthcare (Basel)

Faculty of Medicine, Josip Juraj Strossmayer University of Osijek, 31000 Osijek, Croatia.
Background: Low back pain has frequently been mentioned as the most common sort of chronic pain, and numerous studies have confirmed its influence on the health-related quality of life (HRQoL). Despite a great deal of research demonstrating the important part that psychological factors play in explaining HRQoL, a therapeutic setting that prioritizes the physical domain still predominates. For this reason, the aim of this study is to assess the relationship between age, pain intensity, pain catastrophizing, depression, anxiety, pain-related anxiety, chronic pain acceptance and the psychological and physical dimensions of HRQoL in patients with chronic low back pain (CLBP).

Department of Neurosurgery, Spine and Spinal Cord Institute, Gangnam Severance Hospital, Yonsei University College of Medicine, Seoul, Korea.
Objective: We aimed to investigate the incidence of delayed-onset neurological deficits (DONDs), DOND-related reoperation rates following adult spinal deformity (ASD) surgery, and efficacy of transverse process hooks (TPHs) at the uppermost instrumented vertebra (UIV) compared to pedicle screws (PSs).
Methods: We included 90 consecutive patients who underwent instrumented fusion from the sacrum to the distal thoracic spine for ASD, with a minimum follow-up of 24 months. Clinical and radiological outcomes were compared between 33 patients in the TPH group and 57 patients in the PS group, using the Scoliosis Research Society-22 Outcomes questionnaire (SRS-22), Medical Outcomes Study Questionnaire Short-Form 36 (SF-36), and various spinal sagittal parameters.
