Conclusions The degree of antitumor efficacy was dependent on the type of applied bifunctional chelators conjugated to mAb. However, this difference was not statistically significant. Dosimetry calculations showed that the absorbed radiation doses extrapolated to humans were very low for osteogenic cells regardless of the conjugates. Organs like the liver and spleen, treated with 177Lu-DOTA(SCN)-Rituximab, showed similar radiation absorbed doses when compared with 177Lu-DOTA(NHS)-Rituximab.BACKGROUND The gold-standard method for collecting patient-reported outcomes (PROs) is the prospective assessment of preoperative to postoperative change. However, this method is not always feasible because of unforeseen cases or emergencies, logistical and infrastructure barriers, and cost issues. In such cases, a retrospective approach serves as a potential alternative, but there are conflicting conclusions regarding the reliability of the recalled preoperative PROs after orthopaedic procedures. PURPOSE To assess the agreement between prospectively and retrospectively collected PROs for a common, low-risk procedure. STUDY DESIGN Cohort study (Diagnosis); Level of evidence, 3. METHODS Patients who underwent arthroscopic rotator cuff repair between May 2012 and September 2017 at the study institution were identified. All of the patients completed the American Shoulder and Elbow Surgeons (ASES) Standard Shoulder Assessment Form preoperatively at their preassessment appointment. Patients were then contacted in called PROs were almost always lower than their prospectively recorded counterparts. Selleck Olaparib Recalled PROs are more likely to be accurate when reported by younger patients, those with a longer duration of symptoms, and those with more severe preoperative conditions.RATIONALE Obesity-related asthma disproportionately affects minority children, and is associated with non-atopic T helper (Th) 1 polarized inflammation that correlates with pulmonary function deficits. Selleck Olaparib Its underlying mechanisms are poorly understood. OBJECTIVES Utilize functional genomics to identify cellular mechanisms associated with non-atopic inflammation in obese asthmatic minority children. METHODS CD4+Th cells from 59 obese asthmatic and 61 normal-weight asthmatic Hispanic and African American children underwent quantification of the transcriptome and DNA methylome, and genotyping. Expression and methylation quantitative trait loci (eQTLs and meQTLs) revealed the contribution of genetic variation to transcription and DNA methylation. Adjusting for Th cell subtype proportions discriminated loci where transcription or methylation differences were driven by differences in subtype proportions from loci that were independently associated with obesity-related asthma. MEASUREMENTS AND MAIN RESULTS Obese asthmatics had more memory and fewer naïve Th cells than normal-weight asthmatics. Differentially expressed and methylated genes, and meQTLs in obese asthmatics, independent of Th cell subtype proportions, were enriched in Rho-GTPase pathways. Inhibition of CDC42, one of the Rho-GTPases associated with Th cell differentiation, was associated with downregulation of IFNγ, but not IL-4 gene. Differential expression of RPS27L gene, part of the p53-mTOR pathway, was due to non-random distribution of eQTL variants between groups. Differentially expressed and/or methylated genes, including RPS27L, were associated with pulmonary function deficits in obese asthmatics. CONCLUSIONS We found enrichment of Rho-GTPase pathways in obese asthmatic Th cells, identifying them as a novel therapeutic target for obesity-related asthma, a disease that is sub-optimally responsive to current therapies.Targeted alpha therapy (TAT) offers the potential for the targeted delivery of potent α-particle-emitting radionuclides that emit high linear energy transfer radiation. This leads to a densely ionizing radiation track over a short path. Localized radiation induces cytotoxic, difficult-to-repair, clustered DNA double-strand breaks (DSBs). To date, radium-223 (223Ra) is the only TAT approved for the treatment of patients with metastatic castration-resistant prostate cancer. Thorium-227 (227Th), the progenitor nuclide of 223Ra, offers promise as a wider-ranging alternative due to the availability of efficient chelators, such as octadentate 3,2-hydroxypyridinone (3,2-HOPO). The 3,2-HOPO chelator can be readily conjugated to a range of targeting moieties, enabling the generation of new targeted thorium-227 conjugates (TTCs). This review provides a comprehensive overview of the advances in the preclinical development of TTCs for hematological cancers, including CD22-positive B cell cancers and CD33-positive leukemia, as well as for solid tumors overexpressing renal cell cancer antigen CD70, membrane-anchored glycoprotein mesothelin in mesothelioma, prostate-specific membrane antigen in prostate cancer, and fibroblast growth factor receptor 2. As the mechanism of action for TTCs is linked to the formation of DSBs, the authors also report data supporting combinations of TTCs with inhibitors of the DNA damage response pathways, including those of the ataxia telangiectasia and Rad3-related protein, and poly-ADP ribose polymerase. Finally, emerging evidence suggests that TTCs induce immunogenic cell death through the release of danger-associated molecular patterns. Based on encouraging preclinical data, clinical studies have been initiated to investigate the safety and tolerability of TTCs in patients with various cancers.BACKGROUND Exposure mixtures frequently occur in data across many domains, particularly in the fields of environmental and nutritional epidemiology. Various strategies have arisen to answer questions about exposure mixtures, including methods such as weighted quantile sum (WQS) regression that estimate a joint effect of the mixture components. OBJECTIVES We demonstrate a new approach to estimating the joint effects of a mixture quantile g-computation. This approach combines the inferential simplicity of WQS regression with the flexibility of g-computation, a method of causal effect estimation. We use simulations to examine whether quantile g-computation and WQS regression can accurately and precisely estimate the effects of mixtures in a variety of common scenarios. METHODS We examine the bias, confidence interval (CI) coverage, and bias-variance tradeoff of quantile g-computation and WQS regression and how these quantities are impacted by the presence of noncausal exposures, exposure correlation, unmeasured confounding, and nonlinearity of exposure effects.
