In the past, we have made use of infrared CCD camera to take pictures of vein for vein authentication. However, mounting infrared CCD camera for electrical device is dangerous due to the problem of privacy invasions. In addition, there have been registration problem which lower the correlation. Then, we propose a method that visualizes vein using color information subpixel level image registration technique. These methods do not require infrared CCD camera, and furthermore . Consequently, we create a high-accuracy authentication system without the use of infrared CCD camera.

Purpose: This study assessed the clinical outcomes of periprosthetic joint infection patients who underwent twostage revision total knee arthroplasty with antibiotic-loaded cement spacers fabricated using a handmade silicone mold. Materials and methods: This study included seven patients (average age 77 years, average follow-up time 54 months) who underwent surgery at our hospital between 2009 and 2013. Clinical outcomes including knee scores, function scores, knee range of motion, and walking ability at the final observation, period from the primary total knee arthroplasty to implant removal, period from implant removal to revision total knee arthroplasty, and followup period after revision total knee arthroplasty were investigated. Results: At the final follow-up, the average knee range of motion was 99°, with no significant differences at each stage; average knee and function scores were 84 and 77, respectively. With cement spacers, five patients were able to walk with a t-cane. No recurrence of infection was observed. Conclusions: The clinical outcomes of the current case series demonstrated good knee function with preserved walking ability, without any recurrence of periprosthetic joint infection. This study suggests that using a handmade silicone mold could be an effective option for periprosthetic joint infection after a total knee arthroplasty.

Radially convergent beam fusion (RCBF) has been studied for practical use as a portable neutron/ proton source for various applications such as landmine detection and medical positron emission tomography. However, some problems remain for practical use, and the most critical one is the insufficiency of absolute neutron/proton yields. In this study, a new RCBF device was designed and tested to obtain higher neutron/proton yields. The key features of the new device are the cylindrical electrode configuration in consideration of better electrostatic confinement of ions and extraction of protons, and an integrated ion source. From the experiments using deuterium gas, it was confirmed that the ion source works effectively. At the same discharge condition of voltage and current, the obtained neutron production rate was about one order of magnitude higher than that of the conventional spherical RCBF device. A maximum neutron production rate of 6.8 × 109 n/s was obtained at a pulsed discharge of .70 kV, 10 A. For application as a proton source, proton yield in the RCBF device should be investigated, but the RCBF device also produces X-rays and electrons. To count protons by Solid-State Detector (SSD), it is necessary to eliminate these X-rays and electrons. Therefore, a new proton-counting system that has been designed has three magnetic deflectors. The SSD position was determined by a calculation of the proton trajectory.bt

Background: Management of postprandial hyperglycemia is a key aspect in diabetes treatment. We developed a novel system to measure glucose area under the curve (AUC) using minimally invasive interstitial fluid extraction technology (MIET) for simple monitoring of postprandial glucose excursions. In this study, we evaluated the relationship between our system and continuous glucose monitoring (CGM) by comparing glucose AUC obtained using MIET with that obtained using CGM for a long duration. Methods: Twenty diabetic inpatients wearing a CGM system were enrolled. For MIET measurement, a plastic microneedle array was applied to the skin as pretreatment, and hydrogels were placed on the pretreated area to collect interstitial fluid. Hydrogels were replaced every 2 or 4 hours and AUC was predicted on the basis of glucose and sodium ion levels. Results: AUC predicted by MIET correlated well with that measured by CGM (r=0.93). Good performances of both consecutive 2- and 4-hour measurements were observed (measurement error: 11.7%±10.2% for 2 hours and 11.1%±7.9% for 4 hours), indicating the possibility of repetitive measurements up to 8 hours. The influence of neither glucose fluctuation nor average glucose level over the measurement accuracy was observed through 8 hours. Conclusion: Our system showed good relationship with AUC values from CGM up to 8 hours, indicating that single pretreatment can cover a large portion of glucose excursion in a day. These results indicated possibility of our system to contribute to convenient monitoring of glucose excursions for a long duration.

Background/Aims: Crohn’s disease is a chronic disorder; therefore, it is essential to investigate long-term safety and efficacy of treatments. This study assessed the safety and effectiveness of adalimumab for up to 3 years in Japanese patients with Crohn’s disease in real-world settings. Methods: This was a multicenter, single-cohort, observational study of patients with Crohn’s disease. Safety assessments included incidence of adverse drug reactions. Effectiveness assessments included clinical remis-sion, mucosal healing, and Work Productivity and Activity Impairment (WPAI). Results: The safety and effectiveness analysis populations comprised 389 and 310 patients, respectively. Mean (standard deviation) exposure to adalimumab in the safety analysis population was 793.4 (402.8) days, with a 58.1% retention rate. A total of 105 patients (27.0%) and 43 patients (11.1%) experienced adverse drug reactions and serious adverse drug reactions, respectively, with no patient reporting tuberculosis or hepatitis B. Infections and serious infections were reported in 37 patients (9.5%) and 17 patients (4.4%), respectively. Malig-nancy was reported as an adverse drug reaction in 2 patients (0.5%). Remission rate increased from 37.8% (98/259) at baseline to 73.9% (167/226) at week 4 and remained >70% over 3 years. Proportion of patients without mucosal ulcerations increased from 2.7% (2/73) at baseline to 42.3% (11/26) between years >2 to ≤3. WPAI improvement started at 4 weeks, with the overall work impairment score improving from 42.7 (n=102) at baseline to 26.9 (n=84) at 4 weeks. Conclusions: Results from this study confirm the long-term safety and effectiveness of adalimumab treatment in Japanese patients with Crohn’s disease in the real-world setting.

Study Design: This is a single-center retrospective cohort study with a university hospital setting.Purpose: This study aims to evaluate the short-term course of physical function and walking ability after intramedullary spinal cord tumor (ISCT) resection and predict walking independence 1 year after surgery.Overview of Literature: Although several reports have shown the postoperative functional prognosis of spinal intramedullary tumors with long-term follow-up, no reports have identified the predictors associated with the functional outcome at an early stage. Methods: A total of 79 individuals who underwent ISCT resection at our institute between 2014 and 2019 were enrolled in the study, whose preoperative walking state was independent ambulator regardless of cane support with the Functional Independence Measure Locomotor Scale (FIM-L) score of ≥6. The FIM-L, the American Spinal Injury Association (ASIA) motor and sensory scores in the lower extremities, and the Walking Index for Spinal Cord Injury II (WISCI II) were assessed for walking independence, lower-limb function, and walking ability, respectively. These evaluations were performed at 4 time points: preoperatively, 1 week (1W), 2 weeks (2W), and 1 year after surgery.Results: In the early phase after surgery, 71% and 43% of the participants were nonindependent ambulators at 1W and 2W, respectively. Histopathology indicated that patients with solid tumors (ependymoma, astrocytoma, or lipoma) showed significantly lower indices at 1W and 2W than those with vascular tumors (hemangioblastoma or cavernous hemangioma). Regarding tumor location, thoracic cases exhibited poorer lower-limb function at 1W and 2W and poorer walking ability at 2W than cervical cases. According to the receiver operating characteristic (ROC) analysis, 2 WISCI II points at 2W had the highest sensitivity (100%) and specificity (92.2%) in predicting the level of walking independence at 1 year postoperatively (the area under the ROC curve was 0.99 (95% confidence interval, 0.93–1.00).Conclusions: The higher the lower-limb function scores in the early phase, the better the improvement in walking ability is predicted 1 year after ISCT resection.
