Commutability assessment of new standard reference materials (SRMs) for determining serum total 25-hydroxyvitamin D using ligand binding and liquid chromatography-tandem mass spectrometry (LC-MS/MS) assays.

Commutability is where the measurement response for a reference material (RM) is the same as for an individual patient sample with the same concentration of analyte measured using two or more measurement systems. Assessment of commutability is essential when the RM is used in a calibration hierarchy or to ensure that clinical measurements are comparable across different measurement procedures and at different times. The commutability of three new Standard Reference Materials (SRMs) for determining serum total 25-hydroxyvitamin D [25(OH)D], defined as the sum of 25-hydroxyvitamin D [25(OH)D] and 25-hydroxyvitamin D [25(OH)D], was assessed through an interlaboratory study.

The association between behavioral habits and physical health status in prostate cancer patients: a large US national health-related survey.

Background: The impact of behavioral habits such as exercise on the physical health of prostate cancer (PCa) patients is poorly understood. We aimed to investigate PCa patients' exercise habits and the association between exercise and self-reported physical health status.

Methods: The 2016-2020 Behavioral Risk Factor Surveillance System (BRFSS) databases were used to identify men with a history of PCa.

Peripartum cardiomyopathy in the twenty-first century: a review of the pathophysiology and clinical trials for novel disease-specific therapeutics.

Peripartum cardiomyopathy is an idiopathic and nonischemic systolic dysfunction with onset toward the end of pregnancy and up to 5 months postpartum. Its clinical phenotype overlaps with pregnancy-associated cardiomyopathy rendering both a continuum of the same disease. Incidence varies geographically and is highest in areas where risk factors are prevalent.

Prehabilitative/rehabilitative exercise, nutrition, and psychological support for bladder cancer: A scoping review of randomized clinical trials.

The study of prehabilitation and rehabilitation ([p]rehabilitation) to alleviate the sequelae of bladder cancer and its treatment has generated numerous opportunities to improve the quality of life of bladder cancer survivors. The authors conducted a scoping review of randomized clinical trials (RCTs) to identify knowledge gaps in and research directions for (p)rehabilitative support for those affected by bladder cancer. The authors systematically searched six databases and synthesized key findings from RCTs conducted from January 1, 2004, through March 15, 2022, that enrolled participants with bladder cancer, survivors, or caregivers in outpatient (p)rehabilitative programs (e.

Post-traumatic stress disorder (PTSD) is caused by exposure to a traumatic or stressful event. Symptoms related to this disorder include persistent re-experiencing of memories and fear generalization. Current pharmacological treatments for PTSD are insufficient, with fewer than 30% of patients reporting symptom remission.
