AbstractBackground:Cardiac catheterisations for CHD produce anxiety for patients and families. Current strategies to mitigate anxiety and explain complex anatomy include pre-procedure meetings and educational tools (cardiac diagrams, echocardiograms, imaging, and angiography). More recently, three-dimensionally printed patient-specific models can be added to the armamentarium. The purpose of this study was to evaluate the efficacy of pre-procedure meetings and of different educational tools to reduce patient and parent anxiety before a catheterisation.Methods:Prospective study of patients ≥18 and parents of patients <18 scheduled for clinically indicated catheterisations. Patients completed online surveys before and after meeting with the interventional cardiologist, who was blinded to study participation. Both the pre- and post-meeting surveys measured anxiety using the State-Trait Anxiety Inventory. In addition, the post-meeting survey evaluated the subjective value (from 1 to 4) of individual educational tools: physician discussion, cardiac diagrams, echocardiograms, prior imaging, angiograms and three-dimensionally printed cardiac models. Data were compared using paired t-tests.Results:Twenty-three patients consented to participate, 16 had complete data for evaluation. Mean State-Trait Anxiety Inventory scores were abnormally elevated at baseline and decreased into the normal range after the pre-procedure meeting (39.8 versus 31, p = 0.008). Physician discussion, angiograms, and three-dimensional models were reported to be most effective at increasing understanding and reducing anxiety.Conclusion:In this pilot study, we have found that pre-catheterisation meetings produce a measurable decrease in patient and family anxiety before a procedure. Discussions of the procedure, angiograms, and three-dimensionally printed cardiac models were the most effective educational tools.

In femoral head necrosis, the cortical shell of the femoral head collapses and buckles into the cancellous bone. The purpose of this study is to explore the biomechanical characteristics of the femoral head and the necrosis region by comparing the results before and after drug treatment. In this paper, we study two patient cases with femoral head necrosis disease and establish the corresponding computational three-dimensional models. The results show that the deformation of the femur decreases slightly after the treatment, the equivalent stress distributes more evenly, and the stress magnitude reduces. The results also reveal that the volume of the necrosis in the femoral head decreases after treatment, the overall necrosis presents relatively lower equivalent stress, and the area with the relatively high equivalent stress is smaller comparing to the necrosis in femoral head before treatment.

This study aimed to determine the association of teardrop angle and anteroposterior distance with anterior lunate facet displacement and articular congruity before and after anterior plating of distal radial fractures. We included 36 patients with complete intra-articular distal radial fractures with separate anterior lunate facet fragments. On radiographs we determined the teardrop angle and anteroposterior distance. On digital three-dimensional models we measured proximal-distal, anteroposterior and ulnoradial anterior lunate facet displacement, and we outlined the gap surface area. Preoperatively, teardrop angle was highly associated with the extent of anterior lunate facet displacement. Increased anteroposterior distance was mainly associated with articular incongruity after anterior plate fixation. This information may reduce the need of preoperative computed tomography scans in fractures with a normal tear drop angle. This is particularly useful in low-resource settings.

The present study assessed the test-retest scores of a Dutch version of the State-Trait Anxiety Inventory before and after surgery. The State and Trait-Anxiety scales of a Dutch version were administered to 159 surgical patients on the day before the operation and again three days later. After surgery, a significant decrease was found in State Anxiety and anxiety assessed by the two subscales within this scale, i.e., State Anxiety present and State Anxiety absent. Trait anxiety decreased only slightly.

Abstract Objective Patients with advanced prostate cancer are suitable candidates for [177Lu]PSMA-617 therapy. Integrated SPECT/CT systems have the potential to improve the accuracy of patient-specific tumor dosimetry. We present a novel patient-specific Monte Carlo based voxel-wise dosimetry approach to determine organ and total tumor doses (TTD). Methods 13 patients with histologically confirmed metastasized castration-resistant prostate cancer were treated with a total of 18 cycles of [177Lu]PSMA-617 therapy. In each patient, dosimetry was performed after the first cycle of [177Lu]PSMA-617 therapy. Regions of interest were defined manually on the SPECT/CT images for the kidneys, spleen and all 295 PSMA-positive tumor lesions in the field of view. The absorbed dose to normal organs and to all tumor lesions were calculated by a three dimensional dosimetry method based on Monte Carlo Simulations. Results The average dose values yielded the following results: 2.59 ± 0.63 Gy (1.67–3.92 Gy) for the kidneys, 0.79 ± 0.46 Gy (0.31–1.90 Gy) for the spleen and 11.00 ± 11.97 Gy (1.28–49.10 Gy) for all tracer-positive tumor lesions. A trend towards higher TTD was observed in patients with Gleason Scores > 8 compared to Gleason Scores ≤ 8 and in lymph node metastases compared to bone metastases. A significant correlation was determined between the serum-PSA level before RLT and the TTD (r = –0.57, p < 0.05), as well as between the TTD with the percentage change of serum-PSA levels before and after therapy was observed (r = –0.57, p < 0.05). Patients with higher total tumor volumes of PSMA-positive lesions demonstrated significantly lower kidney average dose values (r = –0.58, p < 0.05). Conclusion The presented novel Monte Carlo based voxel-wise dosimetry calculates a patient specific whole-body dose distribution, thus taking into account individual anatomies and tissue compositions showing promising results for the estimation of radiation doses of normal organs and PSMA-positive tumor lesions.

Comparison Of The Results

The aim of the study was to evaluate the effectiveness of a non-invasive method of treating caries at the stage of a white chalky spot with the Infiltration Concept (Icon) technology. Materials and methods: the clinical and laboratory study included 5 teeth with caries in the white spot stage, removed according to orthodontic indications. The study included scanning in an X-ray computer microtomograph of selected samples of teeth with caries in the white spot stage before and after treatment of the caries area according to Icon technology. For each sample, 1601 X-ray projections were obtained, which were then reconstructed using the XRM Reconstructor software. The comparison of the mineralization density of the samples was carried out by calibrating the obtained images, reconstructing three-dimensional models of tooth samples and constructing maps of the mineralization fee. Results and conclusions. Data on the mineralization density before and after treatment according to Icon technology were obtained in the following areas of the studied teeth: caries in the white spot stage; dentin bordering on caries (the area touches the dentinoemal border as close as possible to the caries area); the area of healthy enamel on the opposite side of the tooth; dentin bordering on healthy enamel (near the dentinoemal border and as close as possible to the healthy enamel area). A comparison of the results obtained does not allow us to conclude about the effectiveness of treatment according to the Icon technology. Moreover, the mineralization density of the studied areas significantly decreased after the treatment.

Abstract Background Preoperative planning of open laryngotracheal surgery is important for achieving good results. This study examines the surgeon’s perception of the importance of using life size 3D printed models of the pediatric airway on surgical decision making. Methods Life-size three-dimensional models of the upper airway were created based on CT images of children scheduled for laryngotracheal-reconstruction and cricotracheal resection with anastomosis. Five pediatric airway surgeons evaluated the three-dimensional models for determining the surgical approach, incision location and length, graft length, and need for single or double-stage surgery of seven children (median age 4.4 years, M:F ratio 4:3). They rated the importance of the three-dimensional model findings compared to the direct laryngoscopy videos and CT findings for each domain on a validated Likert scale of 1–5. Results The mean rating for all domains was 3.6 ± 0.63 (“moderately important” to “very important”), and the median rating was 4 (“very important”). There was full agreement between raters for length of incision and length of graft. The between-rater agreement was 0.608 (“good”) for surgical approach, 0.585 (“moderate”) for incision location, and 0.429 (“moderate”) for need for single- or two-stage surgery. Conclusion Patient-specific three-dimensional printed models of children’s upper airways were scored by pediatric airway surgeons as being moderately to very important for preoperative planning of open laryngotracheal surgery. Large–scale, objective outcome studies are warranted to establish the reliability and efficiency of these models. Graphical abstract

This study aims to analyze the convergent validity of an instrument for the three-dimensional measurement of mood states: the POMS-VIC. The instrument was applied to 62 students from the UAM Sports Service. The scores offered by the athletes when completing the POMS-VIC and other similar tests (PIED) Interactive Profile of Moods, (Barrios & González, 2012); (STAI) State-Trait Anxiety Inventory (Guillén-Riquelme & Buela-Casal, 2011) and (CSAI-2R) Revised Competitive State Anxiety Inventory-2 (Andrade et al., 2007) were compared. The correlation coefficient was calculated by Spearman rank and non-parametric group contrast using the Mann Whitney U test. Appreciating mean correlations between PIED and POMS_Intensidad (rho=-.61), POMS_Valencia (rho=.34) and POMS_Control (rho=.43). As well as between POMS_Intensidad and the three subscales of CSAI (Cognitive, rho=-.31), (Somatic, rho=-.55) and (Selfconfidence, rho=.56). It is concluded that there is a considerable relationship between the POMS-VIC and the considered instruments. This result implies that the proposal scale is valid for the mood state measurement and allows its use in the sports field. Therefore, the instrument is considered to have an important practical impact for sport psychology.
