Comparative Study With Different Tracers (18F-FDG and 68Gallium Citrate) in the Diagnosis of Periprosthetic...
Infection and Inflammatory Reaction Due to Internal Joint ProsthesisThis is an open-labelled two-arm pilot comparative prospective study. All the subjects will undergo image assessment in the two stages of exchange arthroplasty surgery. At the first stage, each enrolled subject will receive both FDG and Ga68 citrate PET/CT scans before the first operation for periprosthetic Joint Infection (PJI). Thus, the test results of FDG and Ga68 for each individual can be obtained. After the first operation, the surgery/biopsy proof can be obtained as the gold standard. The subjects those with PJI negative will complete the process at the first stage. And the second stage of this study will be based on the subjects with positive PJI from the first operation. They will receive both FDG and Ga68 citrate PET/MR scans after antibiotic bone cement was implanted. The sensitivity/accuracy of the two tracers for PET/MR can be calculated and compared. This stage is aimed to answer whether PET/MR scan is a feasible imaging tool to provide diagnostic information of infection control status after the resection arthroplasty of hip/knee PJIs, especially with the implantation of antibiotic loaded bone cement. In the second stage, the investigators shift the imaging modality to PET/MR based on the following reasons: (1) MRI itself has no radiation burden; (2) MRI provides more accurate tissue contrast information and therefore better anatomic delineation; and (3) currently there was no study indicating the existence of ABLC may hamper the interpretation of images. The study duration is expected to be completed in a period of 3 year. It plans to enrol a total of 40 evaluable subjects with suspicious. And we expect the PJI prevalence will be around 75%, i.e. the anticipated number of subjects of true PJI is around 30. The sample size and the prevanence is given based on the clinical availability and consideration.
Effects of Postdilution Online Hemodiafiltration With AcEtate-free Citrate dialySis Fluid on Inflammation...
ESRDThe aim of this study was to evaluate the effect and timing of action on the inflammatory state of a acetate-free containing citrate concentrate (Cit-, 1 mM Citrate) in online postidultion HDF with high volumes compared to traditional concentrated (Ac-, 3 mM of acetate ) in the medium term. In addition, the study will evaluate other parameters of efficiency dialysis, cardiovascular stability, the safety of the concentrate with regard to bone metabolism and vessel calcification in the medium term.

Cytokines and Vascular Inflammation in Psoriasis
Vascular InflammationPsoriasis1 morePsoriasis is an inflammatory disease involving the skin, the joints and the vascular compartment. The mechanisms linking inflammation in the skin and joints and in the vascular walls are poorly understood. One hypothesis for the increase in vascular inflammation observed in patients with psoriasis involves circulating pro-inflammatory cytokines. Patients with psoriasis have an increase in serum levels of tumor necrosis factor alpha (TNF-alpha), Interleukin-17 (IL-17), IL-22, IL-6 as well as a the chemokine S100A913. It is possible that one of those cytokines/chemokine induces vascular inflammation in the vascular compartment. The purpose of this cross sectional retrospective study is to highlight the correlation between vascular wall inflammation using 18F-2-fluoro-2-deoxy-D-glucose - Positron Emission Tomography (FDG-PET) fluorodeoxyglucose technology and pro-inflammatory cytokines/chemokine.
Yogurt for Prevention of Chronic Inflammation
ObesityInflammationThe objective of this study is to conduct a randomized cross-over dietary intervention in adult women who are overweight or obese to compare how yogurt and a control food affect biomarkers of inflammation and intestinal health.
Inflammatory Markers in Hysterectomies
Gynecologic DiseaseInflammationThis retrospective study was conducted in the obstetrics and gynecology clinic at Derince Training and Research Hospital. The study group was identified as patients who underwent hysterectomy between 2018 and 2019. Our hospital is a 50-bed tertiary reference center where approximately 3,500 births per year occur, and about 500 gynecological-oncological surgeries are performed annually. The records of patients who underwent LH and AH were reviewed retrospectively. Preoperative and postoperative blood values in the first 24 hours after surgery were compared: hematocrit (HCT), hemoglobin (HB), WBC, PLR, and NLR values were compared as well as the demographic characteristics of the patients who underwent these procedures. In addition, to evaluate the effect of ovaries on the inflammatory markers, the patients were divided into two groups: oophorectomy and non-oophorectomy. In our clinic, the decision to perform a hysterectomy is made by the weekly gynecology council. The type of surgery is determined according to the clinical condition of the patient, the gynecological examination, and the patient's request. In general, open surgery is preferred in patients with giant fibroids, many previous surgeries, and immobile uteri. Conditions such as dysfunctional uterine bleeding, cervical intraepithelial neoplasms, and uterine descensus indicate the need for LH. In cases where there is no clinical suspicion, oophorectomy is performed according to the patients' wishes. In benign cases, the preferred type of hysterectomy is type 1 extra facial hysterectomy. In LH, the procedure is performed as follows: The uterine manipulator is inserted vaginally. First, a Veress needle and then a trocar are entered through the umbilicus. The abdomen is insufflated with carbon dioxide, and the appropriate number of ports is placed. Uterine ligaments and vessels are cut by using bipolar energy. The uterus is removed through the vagina, and the vaginal cuff is sutured laparoscopically. Patients with chronic diseases (e.g., hypertension, diabetes mellitus, and rheumatologic, nephrological, and hematological diseases), the presence of active infection, corticosteroid use, acetylsalicylic acid, and anticoagulant use were not included in the study. Bladder and bowel injuries, blood transfusion requirements, wound infection and hematoma, postoperative respiratory system complications (e.g., atelectasis) were evaluated as surgical complications.

ObesityChildhood4 moreEligible candidates will be recruited within the children with overweight and obesity having a metabolic risk evaluation before treatment in the period 2006 and 2010 at the pediatric clinic of the UZ Brussel In total 60 participants will be investigated. Firstly, 30 participating patients with initially elevated hsCRP will be selected at random ( following the date of their initial investigation) and afterwards matched for age, BMI z-score, and blood pressure with the same number of patients without initially elevated hCRP values Data will be collected as follows: questionnaires clinical examination/ anthropometry blood sample (hsCRP) peripheral arterial tonometry (endoPAT)
Peri-vascular Adipose Tissue Inflammation Evaluated Using Coronary CT Angiography
Cardiovascular Risk FactorThe P-VECT Study proposes to test the use of CCTA-derived FAI measurements in a group of patients with coronary artery inflammation, who will receive routinely-used statin and aspirin treatment. The P-VECT Study is a pilot study that will provide the rationale and data for power calculations to enable design of pivotal trials of the clinical effectiveness of FAI.
Anemia and Inflammation
Iron Deficiency AnemiaInflammationDuring inflammation hepcidin concentrations are increased, leading to a decrease in iron absorption. In iron deficiency anemia hepcidin is suppressed due to the activation of erythropoiesis. Whether inflammation or anemia has the stronger effect on hepcidin is uncertain.
