New (non-immunotherapeutic) treatment-strategies for AML/MDS-patients are under development. Dendritic cells (DCs) and 'leukemia-derived DC' (DCleu) connect the innate and the adaptive immunesystem and (re-)activate it, in their capacity as professional antigen-presenting cells (APCs). They can be generated ex vivo from peripheral blood mononuclear cells (PBMNCs) or whole blood (WB), containing the -physiological-cellular/soluble microenvironment of individual patients using various DC/DCleu-generating methods or (for WB) minimalized 'Kits', containing granulocyte-macrophage-colony-stimulating-factor (GM-CSF) and a second response-modifier. Proof for DC/DCleu-mediated activation of the immune-system after T-cell-enriched mixed lymphocyte culture (MLC) is done by flowcytometry, demonstrating increased fractions of certain activated, leukemia-specific or antileukemic cell-subsets of the innate and the adaptive immune-system. Generation of DC/DCleu is possible independent of patients' age, MHC-, mutation- or transplantation-status. In vivo-treatment of AML-/MDS-patients with blast-modulating, DC/DCleu- inducing 'Kits' could contribute to create migratory DCs, as well as antileukemically reactivated and memory-mediating immune-cells, which patrol tissue and blood and could contribute to stabilizing disease or remissions.Background Experience with retrieval of a Watchman left atrial (LA) appendage (LAA) closure device (WD) is limited. An embolized or grossly malpositioned WD warrants retrieval to minimize the risk of thromboembolic complications and vascular occlusion. Objective The purpose of this study was to report approaches for percutaneous retrieval of a WD from multicenter experience. Methods Data on successful WD retrievals were obtained from high-volume operators. Data included clinical characteristics; structural characteristics of the LA and LAA; and procedural details of the deployment and retrieval procedure, type of retrieval (immediate during the same procedure; delayed during a separate procedure after the successful deployment), equipment used, complications, and postretrieval management. Results Ten successful percutaneous and 1 surgical retrievals comprised this study. Seven patients had immediate retrieval, while 4 had delayed retrieval. The median duration before delayed retrieval was 45 days (range 1-45 days). The median LAA diameter and size of a successfully deployed WD was 16 mm (range 14-24 mm) and 21 mm (range 21-30 mm), respectively. A WD was retrieved from the LA (n = 1), LAA (n = 2), left ventricle (n = 2), and aorta (n = 6). The reason for retrieval from the LAA was inadequate deployment, resulting in a significant peri-device leak. Retrieval from the LA or LAA was successfully performed using snares (n = 2) and a Raptor grasping device (n = 1). Retrieval from the left ventricle was achieved with a snare (n = 1) and surgery (n = 1). Retrieval from the aorta required snares (n = 5) and retrieval forceps (n = 1). Five patients were successfully reimplanted with a larger size WD. The only complication during percutaneous retrieval was a pseudoaneurysm. Conclusion Retrieval of an embolized or malpositioned WD is feasible, and familiarity with snares and grasping tools can facilitate a successful removal.Purpose Oxidative stress may play an important role in childhood obesity and increased cardiometabolic risk. 8-oxo-7,8-dihydroguanosine (8-oxoGuo) from oxidation of RNA and 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG) from oxidation of DNA are excreted into urine and function as biomarkers for oxidative stress reflecting the modification rate of nucleic acids by oxidation. This study investigates the associations between urinary markers of nucleic acid oxidation and Body Mass Index (BMI), age, sex and cardiometabolic risk factors in children and adolescents with and without obesity. Methods We studied 543 children and adolescents from an obesity clinic cohort (n = 418) and a population-based cohort (n = 125), all aged 6-18 years. Anthropometrics, urine and blood samples were collected. A validated liquid chromatography-tandem mass spectrometry method was used to measure the nucleic acid oxidation markers. Results Compared with the population-based cohort, children and adolescents in the obesity clinic cohort had higher calculated 24-h excretion of 8-oxoGuo (p = 0.045) and 8-oxodG (p = 0.014) adjusted for basal metabolic rate. Both oxidation markers were positively associated with age and female sex (all p less then 0.002). In the obesity clinic cohort the RNA oxidation marker 8-oxoGuo correlated with serum insulin (rho = 0.18, p = less then .001) and insulin resistance (rho = 0.19, p = less then .001). Conclusions Childhood obesity associate with higher urinary excretion of nucleic acid oxidation biomarkers, and increase with age throughout childhood, mirroring the obesity- and age-related increase shown in adults. Finally, children with obesity and insulin resistance had higher RNA oxidation markers than children with obesity and no insulin resistance, supporting a possible link between oxidative stress and the pathogenesis of cardiometabolic risk including type 2 diabetes.Resting-state functional MRI (rs-fMRI) is a task-free method of detecting spatially distinct brain regions with correlated activity, which form organised networks known as resting-state networks (RSNs). Anisomycin in vivo The two most widely used methods for analysing RSN connectivity are seed-based correlation analysis (SCA) and independent component analysis (ICA) but there is no established workflow of the optimal combination of analytical steps and how to execute them. Rodent rs-fMRI data from our previous longitudinal brain stimulation studies were used to investigate these two methods using FSL. Specifically, we examined (1) RSN identification and group comparisons in ICA, (2) ICA-based denoising compared to nuisance signal regression in SCA, and (3) seed selection in SCA. In ICA, using a baseline-only template resulted in greater functional connectivity within RSNs and more sensitive detection of group differences than when an average pre/post stimulation template was used. In SCA, the use of an ICA-based denoising method in the preprocessing of rs-fMRI data and the use of seeds from individual functional connectivity maps in running group comparisons increased the sensitivity of detecting group differences by preventing the reduction in signals of interest.
