Filter by:Bladder cancer (BC) is one of the most common type of cancer globally. Due to its high incidence rate, high risk of recurrence and progression, and frequent cystoscopy surveillance, BC contributes to major healthcare costs across the world. The goal of this prospective study was to evaluate the prognostic value of novel non-muscle invasive bladder cancer (NMIBC) biomarkers for predicting disease recurrence or progression after radical transurethral resection of bladder tumour (TURBT). The data obtained from this study may help physicians identify patients who are at greater risk of NMIBC recurrence or progression and require close supervision.
The goal of this interventional study is to evaluate the impact of Hospital Clowns (HCs) intervention, besides to hospital hosting conditions, in the well-being of adult female patients during ambulatory chemotherapy. The main question[s] it aims to answer are: - Do the short-term HCs interventions during ambulatory chemotherapy may increase well-being of adult cancer patients in comparison to the hospital hosting conditions? - Do the short-term HCs interventions, besides the hospital hosting conditions, have effects on well-being biomarkers in association with psychological outcomes? Participants self-collect a sample of saliva followed by psychological assessment, at a first time-point (basal) and at a final time-point (~after 90 minutes of basal) (pre- and post-test), during the chemotherapy treatment session. Researchers have compared an HCs intervention plus hosting conditions - experimental group, EG, and hosting conditions only - control group, CG, by the repeated measures of pre- and post-test of biomarkers in saliva and the psychological functioning evaluations, to see the degree of the impact of HCs intervention in the well-being of the patients in comparison with normal hosting conditions. Each HCs intervention lasts around 15 minutes, and it is performed in the middle of the procedure between pre- and post-test.
The aim of study is impact of additional treatment with new antidiabetic drugs (semaglutide or empagliflozine) compared to control group in T1DM patients - impact on endothelial function measured by FMD and FPF, arterial stiffness - measured by PWV, inflammatory biomarkers, markers of oxidative stress and endothelial progenitor cells (CD 34+/VDRL2, CD 133+/VDRL2) and correlation with glucovariability or time in range, measured with CGM system.
The goal of this food intervention study is to screen/validate the whole grain food intake biomarker in health Chinese's population.
The study has a mixed-methods design i.e. integration of qualitative and quantitative data within a single investigation. Participants included will be patients ≥60 years that are undergoing major elective joint replacement surgery (n=40) and their relative. Patient's experience of his/her cognition will be capture by interviews on postoperative day 13-16 during the follow-up visit and after 1 year. A relative will also be interviewed once on postoperative day 13-16. Cognitive function will be measured preoperatively and on postoperative day 13-16 using the International Study Group of Postoperative Cognitive Dysfunction (ISPOCD) test battery. Symptoms / discomfort will be measured pre- and postoperatively (on postoperative day 1 and 2 and at the follow up visit day 13-16) by the Swedish version of Quality of Recovery (SwQoR) and by a visual analogue scale assessing pain intensity. Biomarkers will also be collected at the same time points. The findings from the interviews will be sorted out depending on group stratification (no delayed neurocognitive recovery and delayed neurocognitive recovery). The qualitative and quantitative findings will be compared to seek for similarities and differences.
This three-arm cross-over randomized clinical trial (allocation ratio of 1:1:1) will aim to explore whether the application of intermittent vibratory forces modify RANKL and OPG concentrations in patients undergoing orthodontic treatment with clear aligners. The specific objective will be to compare gingival crevicular fluid concentrations of RANKL and OPG among groups according to the application or not of Acceledent® treatment at different time points and frequencies of aligner changes.
After written consent from next-of-kin patients with severe traumatic brain injury was included from the neurointensive care unit (NICU) at Sahlgrenska university hospital, Gothenburg. Blood and CSF samples were collected during the initial 3 weeks after trauma. 1 year after trauma patients were assessed according to Glasgow outcome scale (GOS), NIHSS and Barthels. 10-15 years after trauma a repeated evaluation according to GOS was performed by telephone. Different biomarkers such as Neurofilament light, Glial fibrillary acidic protein and Tau among others, was analyzed from serum and CSF samples. Further patients were explored Apolipoprotein-E genetype (APOE). The investigators hypothesize that higher biomarkers concentrations and positive test for this gene relate to worse outcome 1-year and 10-15 years after trauma. Further that these biomarkers and genetic marker further have prognostic value on outcome 1-year and 10-15 years after trauma. Finally, the investigators want to explore the concentrations dynamics of these biomarkers in serum and CSF in the acute phase after trauma.
Mitochondrial and oxidative stress participate in the pathogenic mechanisms of carbon monoxide (CO)-induced toxicity. Thus, serum indicators of mitochondrial and oxidative stress could be useful for predicting neurocognitive prognosis of post-CO poisoning. This prospective observational study of consecutive patients requiring hyperbaric oxygen therapy (HBO2) for acute CO poisoning measured serum biomarkers of mitochondrial (growth differentiation factor 15 [GDF15]; fibroblast growth factor 21 [FGF21]) and oxidative (8-Oxo-2'-deoxyguanosine [8-OHdG] and malondialdehyde [MDA]) stresses at arrival at the emergency department (0 h), and at 24 h and 7 days after HBO2 completion. We evaluated neurocognitive outcomes using the Global Deterioration Scale (GDS; favorable [1-3 points] or poor [4-7 points] outcomes).
This study aims to describe the dynamic changes in nutritional biomarkers in the blood during the postprandial period, i.e. the time period from the last meal and into the fasting state. In total 36 healthy, young men and women will be recruited in Bergen, Norway, and after receiving a standardized breakfast meal they will consume only water for the next 24 hours.
Some patients with subjective cognitive decline (SCD) progress to neurocognitive disorders (NCD), whereas others remain stable; however, the neuropsychological determinants of this progression have not been identified. The investigators objective was to examine baseline neuropsychological indicators that could discriminate between people in whom the SCD progressed to a mild or major NCD and people in whom the SCD remained stable. The investigators retrospectively included patients consulting for SCD at a university medical center's memory center (Amiens, France) and who had undergone three or more neuropsychological assessments at least 6 months apart. The relationship between domain-specific scores and the global cognitive score (GCS, as a function of final status (stable SCD vs. progression toward a mild or major NCD)) was examined using a generalized linear mixed model.
