ABSTRACT

OBJECTIVES: To investigate predictors indicating the continuous need for a knee-ankle-foot orthosis (KAFO) at 1 month after stroke onset in patients who cannot walk without a KAFO in the acute period. MATERIALS AND METHODS: We enrolled patients with severe hemiplegia (n = 139) who were unable to walk without a KAFO on day 10 from stroke onset. The patients were divided into two groups depending on the need for a KAFO at 1 month after the onset: the KAFO group and non-KAFO group. Logistic regression analysis was used to identify predictors of the continuous need for a KAFO at 1 month after stroke onset. In addition, significant predictors were analyzed using receiver operating characteristic curves. RESULTS: The number of patients in the KAFO group and non-KAFO group was 72 (51.8 %) and 67 (48.2 %), respectively. Motor deficit, sensation disorder, severity of pusher syndrome, and body mass index were identified as predictors of the continuous need for a KAFO. Moreover, active range of motion of knee extension on the affected side was found to have the highest predictive ability, with an area under the receiver operating characteristic curve of 0.89 (95 % confidence interval, 0.83-0.94). CONCLUSIONS: In this study, multiple factors were associated with the continuous need for a KAFO at 1 month after stroke onset. In particular, active range of motion of knee extension on the affected side is suggested to be a highly accurate predictor for the need for a KAFO in the subacute phase.

ABSTRACT

BACKGROUND: Accurate prediction of recovery is essential to determine whether a knee-ankle-foot orthosis (KAFO) is required in the subacute phase of stroke. However, there are currently no reliable methods to predict such recovery. OBJECTIVE: This study aimed to determine whether muscle strength of the affected lower limb (affected side LL strength) in stroke patients in the subacute phase who cannot walk without a KAFO can be used to predict the continuous need for a KAFO, using a hand-held dynamometer. METHODS: We enrolled patients with severe hemiplegia (n = 51) who were unable to walk without a KAFO for 10 days after stroke onset. They were divided into two groups depending on the continuous need for a KAFO at 1 month after onset; the KAFO and non-KAFO groups. Logistic regression analysis was used to investigate whether the affected side LL strength was a predictor of the continuous need for a KAFO at 1 month after onset. In addition, significant predictors were analyzed using receiver operating characteristic (ROC) curves. RESULTS: The KAFO and non-KAFO groups included 23 (45.10%) and 28 (54.90%) patients, respectively. The affected side LL strength and pusher syndrome severity were identified as predictors of the continuous need for a KAFO. The predictor with the highest predictive ability was the affected side LL strength, with an area under the ROC curve of 0.80 (95% CI, 0.68-0.93). CONCLUSIONS: Affected side LL strength may be a highly accurate predictor of the need for a KAFO in the subacute phase of stroke.

ABSTRACT

Acupuncture is used to treat a wide variety of eye diseases, although there is little evidence about the effects of acupuncture treatment and the mechanisms responsible for them. Foot acupuncture treatment has effects in both mice and humans. The purpose of this study was to investigate the effects of acupuncture treatment on ocular blood flow in mice. We evaluated ocular blood flow in C57BL/6J mice after foot acupuncture treatment using laser speckle flowgraphy. The mean blur rate, which is an index of blood flow velocity, was increased in the foot acupuncture group. Our results showed that, after 3 minutes' foot acupuncture, ocular blood flow was significantly increased in both the blood vessels and tissue of the eye in C57BL/6J mice. Thus, performing acupuncture in mice might help to determine its effects. Furthermore, acupuncture is considered to be a possible treatment for ocular disease.

ABSTRACT

INTRODUCTION: Focused ultrasound can stimulate a specific point of tissue and can be a noninvasive method for acupoint stimulation. The aim of this study was to clarify the effects of acupoint stimulation by focused ultrasound on blood flow volume and coldness of the fingers and toes. MATERIALS AND METHODS: Forty healthy volunteers were included in this experiment. The blood flow volume and the skin temperature of a finger and toe were measured before and after stimulation of the pericardium 6 acupuncture point (PC-6) by focused ultrasound. Subjective coldness of the fingers and toes was also assessed using a visual analog scale (VAS) before and after stimulation. RESULTS: The maximum blood flow volumes of the finger and toe were significantly larger (p < 0.01) than those before stimulation. The maximum skin surface temperatures of the fingers were significantly higher (p < 0.01) than those before stimulation. The VAS scores for subjective coldness of the toes after stimulation were significantly higher (p < 0.01). CONCLUSION: The blood flow volume and skin temperature tended to increase after PC-6 stimulation. The VAS scores also indicated a tendency toward a warmer sensation in the toes after stimulation.

ABSTRACT

An instrumentation technique for real-time, in situ and real space observation of microphase separation was proposed for ultra-high molecular weight block copolymer thin films (1010 kg mol-1, domain spacing of 180 nm) under high solvent vapor swelling conditions. This is made possible by a combination of a homebuilt chamber which is capable of supplying sufficient amount of vapor, and force-distance curve measurements which gives real-time swollen film thickness and allow active feedback for controlling the degree of swelling. We succeeded in monitoring the domain coarsening of perpendicular lamellar structures in polystyrene-block-poly(methyl methacrylate) thin films for eight hours via tapping mode imaging. During the annealing process, the thickness reached a maximum of 8.5 times that of the original film. The series of temporal real space topographic images obtained via this method allowed us to study, for the first time, the growth exponent of the correlation length under solvent vapor annealing.

ABSTRACT

Background: In this study, we investigated the relationship among a history of depression, depressive states, and dementia in a community-based old-old cohort. Methods: From 2012 to 2013, we recruited 200 subjects residing in Tome, Japan. Ultimately, 181 subjects were enrolled in our study and completed the whole study protocol. We used the World Mental Health-Composite International Diagnostic Interview 3.0 to evaluate whether subjects had a history of depression or other affective disorders. Simultaneously, 3.0 Tesla brain magnetic resonance imaging (MRI) was performed for each subject. Results: Of 181 subjects, 66 were normal (clinical dementia rating [CDR] = 0), 88 had MCI (CDR = 0.5), and 27 had dementia (CDR = 1 or above). Nine of the 181 subjects (4.9%) had a history of depressive episodes. CDR was significantly higher in subjects with a history of depression (0.9 vs. 0.4, p = 0.046) than in those without it. Seventy-two of the 181 subjects (39.7%) exhibited depressive symptoms. Subjects with depression exhibited lower Mini-Mental State Examination scores (21.6 vs. 23.3, p = 0.008), higher CDR scores (0.6 vs. 0.3, p = 0.004), and more atrophy of the medial temporal lobe (4.4 vs. 3.7, p = 0.036). Conclusion: A history of depression should be considered a risk factor for all-cause dementia. In the old-old population, depression is associated with a higher prevalence of dementia, lower cognitive performance, and a smaller hippocampus.

ABSTRACT

BACKGROUND/AIMS: No previous studies have explored the relationship between physical activity (PA) and executive dysfunction. METHODS: We retrospectively evaluated the PA for 590 older participants in the Kurihara Project; 221 participants had a Clinical Dementia Rating (CDR) of 0 (healthy), 295 CDR 0.5 (very mild dementia), and 74 CDR 1+ (dementia). RESULTS: In the complicated task, whether the motor intensity was high (e.g. farming) or low (e.g. shopping), PA exhibited an inverse relationship with the CDR level. By contrast, for simple tasks with high intensity (e.g. walking), no CDR group differences were noted. For PA with low intensity (e.g. cleaning), the CDR 1+ group exhibited decreased levels. CONCLUSION: PA was related to the burden of executive function in patients with mild cognitive impairment; however, in patients with dementia, PA was related to both the burden of executive function and motor intensity.

ABSTRACT

The purpose of this study is to examine the feasibility of single-incision laparoscopic percutaneous extraperitoneal closure (LPEC) for incarcerated inguinal hernia (IIH) repair. 6 single-incision LPEC procedures were performed for IIH repair and 60 procedures were performed for reducible inguinal hernia (RIH) in the same period of time in one hospital. The laparoscope and one pair of grasping forceps were placed through the same umbilical incision. In IIH repair, the herniated organ was gently pulled using the grasping forceps with external manual pressure. If it was difficult to reduce the herniated organ with one pair of forceps, another pair of forceps were inserted through a multi-channel port without extending the umbilical incidion. Using the LPEC needle, the hernia orifice was closed extraperitoneally. We performed a retrospective analysis to compare the outcomes of single-incision LPEC for IIH repair or reducible inguinal hernia. All procedures were completed by single-incision without open conversion. A multi-channel port with another pair of forceps was needed in three cases. The operation time and the length of stay were significantly longer with IIH repair than with RIH repair. There were no major complications and there was no evidence of early recurrence in any patient. In conclusion, single-incision LPEC with a multi-channel port is feasible and safe for IIH repair.

ABSTRACT

AIM: After the Great East Japan Earthquake of 2011, we investigated the safety of residents in the affected communities. Most of the people requiring help were elderly and had previously been assessed as Clinical Dementia Rating (CDR) 0.5 (i.e. as having mild cognitive impairment (MCI)). We examined how well they understood the television news and whether they could make appropriate decisions. METHODS: This community-based study of dementia and difficulties following a disaster started in Tome, northern Japan. The subjects were 188 randomly selected older residents who underwent CDR, blood tests, magnetic resonance imaging, and cognitive tests, including an original visual risk cognition task. They were shown NHK news broadcasts from the day of the earthquake to determine whether they could understand the content. RESULTS: Neither the CDR 0 (healthy) nor the CDR 0.5 (MCI) subjects fully understood the television news. Some subjects did not recognize the danger of aftershocks and engaged in risky behaviour. CDR 0.5 subjects who exhibited such behaviour scored lower on the visual risk cognition task. CONCLUSIONS: It is noteworthy that television news is difficult to understand, even for healthy older adults. We found that MCI subjects had particular difficulties due to the disaster and suggest that risk cognition could be evaluated using visually presented materials.

ABSTRACT

PURPOSE: SPECT is an important diagnostic tool for dementia. Recently, statistical analysis of SPECT has been commonly used for dementia research. In this study, we evaluated the accuracy of visual SPECT evaluation and/or statistical analysis for the diagnosis (Dx) of Alzheimer disease (AD) and other forms of dementia in our community-based study "The Osaki-Tajiri Project." PATIENTS AND METHODS: Eighty-nine consecutive outpatients with dementia were enrolled and underwent brain perfusion SPECT with 99mTc-ECD. Diagnostic accuracy of SPECT was tested using 3 methods: visual inspection (SPECT Dx), automated diagnostic tool using statistical analysis with easy Z-score imaging system (eZIS Dx), and visual inspection plus eZIS (integrated Dx). RESULTS: Integrated Dx showed the highest sensitivity, specificity, and accuracy, whereas eZIS was the second most accurate method. We also observed that a higher than expected rate of SPECT images indicated false-negative cases of AD. Among these, 50% showed hypofrontality and were diagnosed as frontotemporal lobar degeneration. These cases typically showed regional "hot spots" in the primary sensorimotor cortex (ie, a sensorimotor hot spot sign), which we determined were associated with AD rather than frontotemporal lobar degeneration. CONCLUSION: We concluded that the diagnostic abilities were improved by the integrated use of visual assessment and statistical analysis. In addition, the detection of a sensorimotor hot spot sign was useful to detect AD when hypofrontality is present and improved the ability to properly diagnose AD.

ABSTRACT

BACKGROUND: Radial artery (RA) pulse diagnosis has been used in traditional Asian medicine. Blood pressure (BP) and pulse rate related to heart rate variability (HRV) can be monitored via the RA. The fluctuation in these parameters has been assessed using fast Fourier transform (FFT) analytical methods that calculate power spectra. METHODS: We measured blood flow volume (Volume) in the RA and evaluated its fluctuations. Normal participants (n = 34) were enrolled. We measured the hemodynamics of the right RA for approximately 50 s using ultrasonography. RESULTS: The parameters showed the center frequency (CF) of the power spectrum at low frequency (LF) and high frequency (HF). More than one spectral component indicated that there were fluctuations. The CF at LF for Volume was significantly different from that for vessel diameter (VD); however, it was significantly correlated with blood flow velocity (Velocity). On the other hand, the CF at HF for Volume was significantly different from that for Velocity; however, it was significantly correlated with VD. CONCLUSION: It is suggested that fluctuation in the Volume at LF of RA is influenced by the fluctuation in Velocity; on the other hand, fluctuation in the Volume at HF is influenced by the fluctuation in VD.

ABSTRACT

BACKGROUND: The aim of this study was to develop a mathematical model of blood flow in the systemic circulation to emulate the change in hemodynamics by acupuncture therapy to elucidate the mechanism of the therapy. For this purpose, as a first step, a simple model of arterial blood flow was presented to reproduce previously reported change in the blood flow volume by the acupuncture needle stimulation of Taichong (LR-3). METHODS: This model was based on the lumped-parameter approximation of arterial blood flow together with linear resistance of peripheral circulation. It has been reported that blood flow in the left arm was enhanced after the stimulation, yielding the peripheral vascular resistance-regulated blood flow dominated by the sympathetic nervous system. In addition to the peripheral resistance, another parameter that possibly regulates the blood flow is the cross-sectional area of the vessel. These two factors were changed to numerically examine their contributions to the blood flow based on the hypothesis that they could be changed by the stimulation. The numerical result was compared with the experimental result to confirm the validity of the hypothesis that the blood flow in the arm is regulated by the peripheral resistance. RESULTS: This model is extremely simple and the physical parameters introduced for the simulation were gleaned from different reports in the literature. It was demonstrated, however, that regulation of the peripheral resistance rather than of the cross-sectional area could reproduce the experimentally observed change in the blood flow. Moreover, the relationship between the changes in the flow volume and the systemic vascular resistance quantitatively matched the experimental data. CONCLUSION: The present model has a potential to emulate hemodynamic change by acupuncture therapy by incorporating physiological correlation of stimulation of an acupoint and regulation of parameters that affect the hemodynamics.

ABSTRACT

BACKGROUND: The effect of acupuncture on sensory perception has never been systematically reviewed; although, studies on acupuncture mechanisms are frequently based on the idea that changes in sensory thresholds reflect its effect on the nervous system. METHODS: Pubmed, EMBASE and Scopus were screened for studies investigating the effect of acupuncture on thermal or mechanical detection or pain thresholds in humans published in English or German. A meta-analysis of high quality studies was performed. RESULTS: Out of 3007 identified articles 85 were included. Sixty five studies showed that acupuncture affects at least one sensory threshold. Most studies assessed the pressure pain threshold of which 80% reported an increase after acupuncture. Significant short- and long-term effects on the pressure pain threshold in pain patients were revealed by two meta-analyses including four and two high quality studies, respectively. In over 60% of studies, acupuncture reduced sensitivity to noxious thermal stimuli, but measuring methods might influence results. Few but consistent data indicate that acupuncture reduces pin-prick like pain but not mechanical detection. Results on thermal detection are heterogeneous. Sensory threshold changes were equally frequent reported after manual acupuncture as after electroacupuncture. Among 48 sham-controlled studies, 25 showed stronger effects on sensory thresholds through verum than through sham acupuncture, but in 9 studies significant threshold changes were also observed after sham acupuncture. Overall, there is a lack of high quality acupuncture studies applying comprehensive assessments of sensory perception. CONCLUSIONS: Our findings indicate that acupuncture affects sensory perception. Results are most compelling for the pressure pain threshold, especially in pain conditions associated with tenderness. Sham acupuncture can also cause such effects. Future studies should incorporate comprehensive, standardized assessments of sensory profiles in order to fully characterize its effect on sensory perception and to explore the predictive value of sensory profiles for the effectiveness of acupuncture.

ABSTRACT

Large-scale (180 × 60 × 1 mm(3)) transmission gratings with groove densities of 1250 and 1740 lines/mm have been developed, resulting in diffraction efficiencies above 95%. The throughput of a folded pulse compressor with two large-scale transmission gratings was approximately 80% in a 20-fs Ti:sapphire chirped-pulse amplification (CPA) laser. The parabolic bending of the transmission grating due to anti-reflection (AR) coating was minimized to 2.9 λ at 633 nm by improving the evaporation process. By a simple analysis, we explain why this level of bending does not induce a wavefront distortion through the transmission grating near the Littrow condition while the wavefront from a reflection grating is distorted to nearly twice the bending of the grating. The calculation based on the measured bending shows that both the group delay difference relative to the ideally flat grating from 750 to 850 nm and the spatial pulse front distortion over a 60-mm-diameter input beam are negligible, even when the dispersive beam covers ~140 mm on the grating. The spatial pulse front distortion measured after the compressor was less than the measurement limit (1.5 fs) for a 20-mm-diameter beam, where the beam size in the dispersive direction on the grating was 85 mm.

ABSTRACT

Large-scale transmission gratings were produced for a stretcher and a compressor in the Yb-fiber chirped-pulse amplification system. A 23-W, 200-fs laser system with a 10-MHz repetition rate was demonstrated. Focused intensity as high as 10(14) W/cm(2) was achieved, which is high enough for multi-photon processes such as high-order harmonics generation and multi-photon ionization of neutral atoms. High-order harmonics up to 7th order were observed using Xe gas as a nonlinear medium.

ABSTRACT

BACKGROUND: Traditional Japanese Medicine (Kampo) is often used in Japan, but very little data on its users are available. We investigated who uses Kampo, the reasons and opinions for its use. METHODS: Questionnaire survey in three Japanese outpatient clinics offering Kampo in different settings: Kampo only, Kampo and traditional Chinese medicine, Kampo and Western medicine. Before seeing the doctor, patients were asked about socio-demographic data, medical history, experience with Kampo, general health-related opinions and behaviours, opinions about Western medicine and Kampo, and reasons for Kampo utilization. Descriptive statistics and predictors for Kampo use were calculated. RESULTS: A total of 354 questionnaires were completed. Participants were 50.97 ± 15.60 (mean ± SD) years of age, 68% were female. Of all patients, 73% (n = 202) were using Kampo currently and 84% (297) had taken Kampo before. Questions on general health-related opinions and behaviour revealed a strong environmental awareness. The most frequent indications for earlier Kampo use were: common cold (36%), gastrointestinal complaints (30%), oversensitivity to cold ("Hi'e-sho"; 29%), stress/anxiety (21%), and shoulder stiffness (20%). Kampo users suffered more often from chronic illnesses (OR 2.88 [1.48-5.58]). Beliefs in underlying philosophy (Wu Xing (adjusted OR 3.08, [1.11-8.55]), Ying and Yang (OR 2.57 [1.15-5.73], a holistic way of seeing the patient (OR 2.17 [1.53-3.08]), and in Kampo efficacy (OR 2.62 [1.66-4.13]) were positively associated with Kampo use. So was, interestingly, conviction of the efficacy of Western medicine (OR 1.87 [1.28-2.74]). Half of the patients had a general preference for a combination of Kampo and Western treatment. CONCLUSIONS: Most patients visiting a clinic that also provided Kampo had previous experience with Kampo. Usage was associated with beliefs in philosophical Kampo concepts and its efficacy.

ABSTRACT

BACKGROUND: Acupuncture is used worldwide in medical treatment. However, needle insertion damages the skin and patients sometimes feel pain. To avoid such drawbacks, an acupoint stimulation device using focused ultrasound has been developed. Ultrasound stimulation does not damage the skin like acupuncture does because ultrasound can deliver vibration energy to soft tissues noninvasively. OBJECTIVES: The aim of this study was to clarify the effect of acupoint stimulation using focused ultrasound. SUBJECTS: Fifty (50) healthy volunteers (40 males and 10 females) were included in this experiment. DESIGN: Subjects were randomly assigned to two groups. LR-3 was stimulated bilaterally for 36 seconds by focused ultrasound and conventional acupuncture. Brachial artery blood flow volume was monitored by an ultrasound with an echo-tracking system. The hemodynamic parameters were measured before, during, and 30, 60, 180 seconds after stimulation. RESULTS: During stimulation, the blood flow volume of the acupuncture stimulation group decreased significantly (p<0.05) compared with resting value, but that of the focused ultrasound stimulation group did not decrease. Blood flow volume of both groups increased gradually and showed significant increase at 180 seconds after stimulation (p<0.05). CONCLUSIONS: Blood flow volume was increased significantly by both focused ultrasound stimulation and conventional acupuncture. Although a significant decrease of blood flow volume during acupuncture stimulation was observed, no such decrease was observed during ultrasound stimulation. Findings of the present study show that noninvasive stimulation of acupoints by focused ultrasound is as effective as conventional acupuncture in blood flow volume of the brachial artery.
