Wirelessly powered dielectrophoresis (DEP) of metal oxide particles was performed using a spark-gap Tesla coil (TC). The main contribution of this work is the simplification of the conventional DEP setup that requires attaching wires directly to the electrodes. Wireless power from the TC generates a high output frequency and voltage, which corresponds to that used for the DEP. Therefore, a spark-gap TC was built and utilized to conduct the DEP process. Metal oxides (ZnO and Fe2 O3 ) were used as targets for the assembly. The results showed that the wirelessly powered DEP technique via a TC was successful in assembling the metal oxide particles. Positive and negative DEP phenomena were observed. Positive DEP occurred during ZnO assembly, making particles chain grow 0.92 mm toward the sparks within 60 s. Negative DEP was observed during Fe2 O3 assembly, where the repulsion of particles formed a void around the sparks with a 1.45 mm radius. The mechanism of this wireless DEP system is discussed.Ascending aortic pseudoaneurysms are rare, but life-threatening conditions, that often require intervention. While endovascular techniques have advanced significantly, the majority of these clinical scenarios preclude endovascular options and the primary treatment modality remains open surgical repair. Repair of an aortic pseudoaneurysm eroding through the sternum resulting in a pulsatile chest wall mass is technically challenging. We report the successful repair of a large ascending aortic pseudoaneurysm in a 62-year-old male with bovine arch anatomy and prior Type A dissection repair, presenting with contained rupture and a pulsatile chest wall mass.Total pancreatectomy with islet autotransplantation is a complex surgical approach for acute recurrent or chronic pancreatitis that frequently triggers extreme thrombocytosis (platelets ≥ 1000 × 109 /L). Thrombocytosis can be prothrombotic, so cytoreductive hydroxyurea is often initiated after this surgery; however, optimal dosing strategy and efficacy are unknown. This prospective pilot study characterized the pharmacokinetics of hydroxyurea after this procedure in children. It also compared them with previously published pediatric parameters in sickle cell anemia (SCA), the disease in which pediatric hydroxyurea pharmacokinetics have primarily been studied. Plasma hydroxyurea levels were quantified in 14 participants aged 4-19 years using high-performance liquid chromatography. Blood collections were scheduled 20 minutes, 1 hour, and 4 hours after the first dose, on pharmacokinetic day 1 (PK1), and again 2-3 months later if still on hydroxyurea (PK2). Six participants had PK1 and PK2 data at all 3 postdose timed collections, 5 only had PK1 samples, and 3 only had PK2 samples. Total pancreatectomy with islet autotransplantation participants had reduced and delayed absorption compared with sickle cell anemia participant data from the Hydroxyurea Study of Long-Term Effects, regardless of timing or dosing methodology. Total pancreatectomy with islet autotransplantation participants had different pharmacokinetic profiles at PK1 versus PK2, with lower dose-normalized exposures than previously reported in sickle cell anemia. These results suggest variability exists in hydroxyurea absorption and bioavailability in total pancreatectomy with islet autotransplantation patients, suspected to be primarily because of Roux-en-Y reconstruction, and suggest that more pharmacokinetic data are needed for scenarios when hydroxyurea is prescribed to children without sickle cell anemia. The Student Practice Evaluation Form-Revised Edition (SPEF-R) is used by all Australian universities to assess the capability and performance of occupational therapy students on block practice placements. The occupational therapy landscape in Australia has evolved significantly since the SPEF-R was developed. This study aimed to review the SPEF-R and develop a revised edition, the SPEF-R2. The first cycle of an action research process involved four phases (a) mapping the SPEF-R to the Australian Occupational Therapy Competency Standards 2018 (AOTCS); (b) development of the SPEF-R2; (c) national consultation through an online survey with clinicians, university staff and students; and (d) reflection and further amendments. In phase 1, good alignment was found between the AOTCS 2018 and the SPEF-R. In phase 2, the SPEF-R2 was developed to further enhance alignment, including expanded content related to culturally responsive practice, reflective practice and clinical/professional reasoning, resulting in tworapy community considers the SPEF-R2 to be a timely and much-needed development. Piloting of the SPEF-R2 and final revisions prior to release are planned for subsequent action cycles and amendments will be made to the online platform and associated training resources. Orthodontic patients are at greater risk due to the inability to clean around the components directly bonded to teeth. check details Hence, the aim of the present network meta-analysis is to compare the utility of powered toothbrushes in plaque control in patients with orthodontic brackets compared with manual tooth brushing. Necessary data were extracted and analysed for Risk of Bias. Heterogeneity was assessed using Chi-square and I tests. Random effects model was used for both direct and mixed treatment comparisons. Standardized mean difference with 95% confidence interval was the effect estimate for plaque and bleeding scores and mean difference for pocket depth. Inconsistencies between the direct and indirect estimates were evaluated by H-statistics. GRADE approach was used to assess the quality of evidence. Pooled results from 14 studies showed significantly higher plaque scores in patients using manual toothbrushes. Pooled results from 13 studies showed significant higher bleeding scores as well with manual brushes. There was a significant reduction in pocket depth with electric toothbrushes. Powered toothbrushes are a promising alternative for plaque control in patients with fixed orthodontic brackets. Stronger evidence can be established with addition of long-term clinical trials based on the recommendations.Powered toothbrushes are a promising alternative for plaque control in patients with fixed orthodontic brackets.
