Attentional disturbance following brain damage is usually evaluated by several neuropsychological tests. In a rehabilitation setting, however, the primary concern is not task performance, but rather functional real-world behavior. To address this requirement, a new assessment system for attentional behavior, BAAD (Behavioral Assessment of Attentional Disturbance), has been developed. This assessment is generally completed by the patient's therapist (occupational therapist, OT) during therapy. The aim of this study was to investigate whether BAAD completed by the family at home (BAAD-FM) yields results that are comparable to BAAD completed by an OT during occupational therapy (BAAD-OT). The subjects were 53 patients with brain damage. BAAD consists of six items thought to be associated with attentional behaviors. Each item is rated (0 to 3) based on the frequency with which the problem behaviors appeared during daily living at home and daily sessions of occupational therapy. The intraclass-correlation coefficient of the total score between BAAD-FM and BAAD-OT was 0.89. The mean (SD) values of the total scores were 3.7 (3.7) and 3.7 (3.6), respectively. Similarly, there were no significant differences in any of the item scores between BAAD-FM and BAAD-OT. The coincidence rate between the two BAAD tests on an item-by-item basis was over 64% for all items but one (43%). In conclusion, the total BAAD-FM score seemed comparable to the total BAAD-OT score and valuable for detecting attentional disturbance.

Objective: Since the conventional drip-infusion method for measuring inulin clearance (Cin) has problems related to its accuracy and performance, we explored a more accurate and concise method by rapid intravenous injection of a newly developed inulin fraction (Inulead®), in which spot urine sampling was omitted and the administration period of inulin was shortened from 120 to 5 minutes. Patients and Methods: Twenty seven patients (M/F: 15/12, 67.8 ± 12.9 years old) admitted to the Nephrology ward were enrolled in this study. Inulead®, 1500 mg dissolved in 150 mL of saline, was intravenously administered in 5 minutes. Then, sequential blood samplings and urine collection were performed for 24 hours. Cins were calculated by the following three formulae: (1) a pharmacokinetic analysis using a two compartments model based on the plasma inulin concentration to determine Cin, which was the administered dose divided by the area under the curve (AUC) from 0 to ∞, (2) urinary inulin excretion divided by the AUC for 24 hours and (3) the Bayesian method using a three-point set of plasma inulin concentrations to predict the change of inulin concentration to determine Cin as in 1. These Cins were compared with levels of estimated GFR (eGFR), creatinine clearance (Ccr), serum β2 microglobulin (β2MG) and serum cystatin C (Cys C). Results: Cins obtained by the above three methods were well correlated with each other (r. = 0.9088 – 0.9998) and with eGFR (r. = 0.8286 – 0.8650), Ccr (r. = 0.821 – 0.864), 1/β2MG (r. = 0.631 –0.752) and 1/CysC (r. = 0.830 – 0.857). The averaged differences of each Cin from eGFR were distributed between –4.4 and –4.5 mL/min. Conclusion: Since the Cins by rapid inulin injection showed satisfactory correlation and differences with other GFR parameters, this method will be a good alternative to the drip infusion method, and may reduce the burden of patients and medical staff.

PREAVOID is pharmaceutical intervention that is utilized to illustrate pharmacists’ contributions to medical care. Currently, there is a great need for pharmacists to provide good medical services to inpatients; as a result, many pharmacists conduct pharmaceutical management in hospital wards. However, pharmacists who have limited experience in working in the ward do not know exactly what they should check with respect to pharmaceutical management. To resolve this problem, we determined 16 pharmaceutical-management items based on PREAVOID that was conducted at Nagara Medical Center. Moreover, we conducted a pre-questionnaire survey assessing whether pharmacists who had worked in the ward for fewer than 4 years attended to these 16 check items in their daily work prior to our introducing the list to them. The results indicated that pharmacists who had fewer than 2 years of experience working in wards attended to the 16 check items less than those who had more than 2 years of experience, and approximately half of the pharmacists had not received adequate guidance before beginning work at the ward. In addition, most pharmacists indicated that clear check points were useful for conducting pharmaceutical management and the 16 check items were useful for their daily work. These results indicate that the 16 check items are a useful educational tool for enabling pharmacists to conduct high quality pharmaceutical management from the initial stage and that using the 16 check items is superior to pharmacists only gaining this ability via prolonged experience working in the ward.

OBJECTIVE: Many studies have reported pre-processing effects for brain volumetry; however, no study has investigated whether non-parametric non-uniform intensity normalization (N3) correction processing results in reduced system dependency when using an atlas-based method. To address this shortcoming, the present study assessed whether N3 correction processing provides reduced system dependency in atlas-based volumetry. MATERIALS AND METHODS: Contiguous sagittal T1-weighted images of the brain were obtained from 21 healthy participants, by using five magnetic resonance protocols. After image preprocessing using the Statistical Parametric Mapping 5 software, we measured the structural volume of the segmented images with the WFU-PickAtlas software. We applied six different bias-correction levels (Regularization 10, Regularization 0.0001, Regularization 0, Regularization 10 with N3, Regularization 0.0001 with N3, and Regularization 0 with N3) to each set of images. The structural volume change ratio (%) was defined as the change ratio (%) = (100 x [measured volume - mean volume of five magnetic resonance protocols] / mean volume of five magnetic resonance protocols) for each bias-correction level. RESULTS: A low change ratio was synonymous with lower system dependency. The results showed that the images with the N3 correction had a lower change ratio compared with those without the N3 correction. CONCLUSION: The present study is the first atlas-based volumetry study to show that the precision of atlas-based volumetry improves when using N3-corrected images. Therefore, correction for signal intensity non-uniformity is strongly advised for multi-scanner or multi-site imaging trials.

Introduction Redox state of glutathione as an oxidative stress marker changes by exercise. Therefore, oxidative stress marker has been used to evaluate the physical condition of athletes. In athletics it is important to prevent fatigue for peak performance. Acupuncture has been used for fatigue prevention of athletes. However, there is little scientific evidence to prove the effect. The purpose of this study is to examine the effects of electroacupuncture (EA) on the change in redox state of glutathione as an oxidative stress marker in the blood by ergometer exercise. Methods In this crossover study, the EA and control (CONT) groups each included 12 healthy male volunteers. EA at 2 Hz and optimum intensity was performed on each subject at both the SP10 (Xuehai) and SP11 (Jimen) locations for 10 min before exercise. Respiratory metabolism was recorded during bicycle ergometer exercise by ramp rate until exhaustion. Blood samples were collected from the fingertip of each subject before and after exercise. Oxidized glutathione (GSSG) and total glutathione (tGSH) concentrations in the blood were biochemically determined as a marker of oxidative stress. The degree of fatigue before and after exercise was evaluated by the visual analogue scale (VAS). Results The ventilatory threshold (VT) and the respiratory compensation point (RC), parameters of respiratory metabolism during exercise, did not differ significantly between the EA and CONT groups. Between both groups, the significant difference was not recognized to the amount of change in tGSH, GSSG, GSH, GSSG/tGSH by exercise. The GSSG/tGSH values after exercise was significantly lower than that before exercise in the EA group (p<0.05). In contrast, this level did not change significantly in the CONT group. The VAS values increased significantly after exercise in both groups (p<0.05); however, the VAS value in EA group showed a low tendency in comparison with that in CONT group. Discussion VT and RC did not differ between the two groups, indicating that the level of exercise was nearly the same for both groups. In comparison of both groups, there was no significant difference on the amount of change of each glutathione parameters by exercise. On the other hand, The GSSG/tGSH and the VAS values after exercise were lower than those values before exercise in the EA group. Therefore, it might be possible that the EA affects the change of the glutathione due to the exercise. Our results might suggest that EA-mediated change of GSH bear some related to suppression of fatigue.
