Aim To investigate the efficacy of adjuvant chemotherapy plus tumor-infiltrating lymphocytes (TILs) therapy in osteosarcoma patients with a poor response to neoadjuvant chemotherapy. Materials & methods 40 patients received adjuvant chemotherapy (Group 1) and 40 patients received adjuvant chemotherapy plus TILs therapy (Group 2). Disease-free survival (DFS) and overall survival (OS) were analyzed by Kaplan-Meier analysis. Results The median DFS (mDFS; 65.3 months) and median OS (mOS; 95.8 months) in Group 2 were significantly prolonged compared with those in Group 1 (55.5 months for mDFS and 80.4 months for mOS). Univariate and multivariate analyses indicated that a greater number of TILs transfused was an independent prognostic factor for both mDFS and mOS. Conclusion Adjuvant chemotherapy plus TILs therapy may prolong survival of patients with a poor response to neoadjuvant chemotherapy.Objective This study aimed to assess the positional relationships between the maxillary sinus and the first and second molars in a western Chinese population by using cone-beam computed tomography. Methods This study included 212 patients (652 maxillary molars and 1956 roots). Patient demographics (sex and age) and cone-beam computed tomography data regarding the relationship between molar roots and the maxillary sinus were obtained. This relationship was stratified into four types for statistical analysis. Results Sex and side did not significantly influence the distance between maxillary molar roots and the maxillary sinus. However, the distance between maxillary molar roots and the maxillary sinus increased with age. The mesiobuccal root of the second molar was nearest to the maxillary sinus. The most common relationship type involved absence of root contact with the sinus border and presence of a maxillary sinus cross-section above the root apex. Conclusions Compared with other teeth, the maxillary posterior teeth have a complex anatomical structure and are closely related to the sinus. These findings may serve as reference information for root canal treatment, tooth extraction, dental implant, and other dental clinical procedures among patients in western China.Aim A major challenge for flow cytometry assays supporting clinical trials is postcollection sample stability. Here we present an approach that could mitigate the stability issue while preserving sample integrity and cellular markers, especially when enumerating rare populations such as Tregs. Materials & methods Stability was evaluated using whole blood stored at room temperature and lysed whole blood stored at -80°C. Results Freezing of lysed whole blood preserved sample integrity and prolonged sample stability for Treg percentage, absolute cell count and median fluorescent intensity values to 11 versus 3 days at room temperature storage. this website Conclusion Frozen storage of lysed whole blood can extend sample stability, improve data quality and facilitate sample batch processing during clinical study sample analysis.Objective The aim of the study was to investigate the effect of augmented feedback on participants' workload, performance, and distribution of visual attention. Background An important question in human-machine interface design is whether the operator should be provided with direct solutions. We focused on the solution space diagram (SSD), a type of augmented feedback that shows directly whether two aircraft are on conflicting trajectories. Method One group of novices (n = 13) completed conflict detection tasks with SSD, whereas a second group (n = 11) performed the same tasks without SSD. Eye-tracking was used to measure visual attention distribution. Results The mean self-reported task difficulty was substantially lower for the SSD group compared to the No-SSD group. The SSD group had a better conflict detection rate than the No-SSD group, whereas false-positive rates were equivalent. High false-positive rates for some scenarios were attributed to participants who misunderstood the SSD. Compared to the No-SSD group, the SSD group spent a large proportion of their time looking at the SSD aircraft while looking less at other areas of interest. Conclusion Augmented feedback makes the task subjectively easier but has side effects related to visual tunneling and misunderstanding. Application Caution should be exercised when human operators are expected to reproduce task solutions that are provided by augmented visual feedback.Background Different antithrombotic treatments, from vitamin K antagonists to direct oral anticoagulants (DOACs), are available to reduce ischemic risks in patients with atrial fibrillation (AF) after percutaneous coronary intervention (PCI). Objective To synthetize evidence about the benefit-risk ratio of antithrombotic treatments and their combinations in patients with AF and PCI. Methods A network meta-analysis and a stochastic multicriteria acceptability analysis (SMAA) were performed including randomized controlled trials (RCT) that evaluate antithrombotic treatments in adults with AF and PCI. Searches were conducted in PubMed and Scopus (updated November-2019). Outcomes compared included bleeding, stroke, and death (Prospero registration CRD42019146813). Results Five RCTs were included (11 532 patients). Vitamin K antagonists + dual antiplatelet therapy was associated with major bleeding (odds ratio 0.52 [95% CI 0.32-0.86]) compared to DOAC + P2Y12. No statistical differences were found among DOAC regimens for the main outcomes, including bleeding, stroke, and death. Surface under the cumulative ranking curve analysis (SUCRA) and SMAA demonstrated edoxaban 60 mg + P2Y12 inhibitor as the worst option (28%). Apixaban 5 mg + P2Y12 inhibitor was the safest alternative (63%) in all scenarios. Conclusions Insufficient evidence on the clinical superiority among anticoagulant regimens exists, although apixaban slightly stands out. Edoxaban was associated with more adverse events. To strength this evidence, well-designed, low risk of bias clinical trials are needed. Cost-minimization analyses are required to provide further information for clinical decision-making.
