    Abstract: Background. Most studies of bilateral arm training (BAT) did not employ a randomized controlled trial design and involved very limited functional training tasks. Objective . Compare the effects of BAT with control intervention (CI) on motor control and motor performance of the upper extremity and also functional gains in patients with chronic stroke. Methods. This 2-group randomized controlled trial with pretreatment and posttreatment measures enrolled 33 stroke patients (mean age = 53.85 years) 6 to 67 months after onset of a first stroke. They received either a BAT program concentrating on both upper extremities moving simultaneously in functional tasks by symmetric patterns or CI (control treatment) for 2 hours on weekdays for 3 weeks. Outcome measures included kinematic analyses assessing motor control strategies for unilateral and bimanual reaching and clinical measures involving the Fugl-Meyer Assessment (FMA) of motor-impairment severity and the Functional Independence Measure (FIM) and the Motor Activity Log (MAL) evaluating functional ability. Results. After treatment, the BAT group showed better temporal and spatial efficiency during unilateral and bilateral tasks and less online error correction only during the bilateral task than the control group. The BAT group showed a significantly greater improvement in the FMA than the control group but not in the FIM and MAL. Conclusions. Relative to CI, BAT improved the spatiotemporal control of the affected arm in both bilateral and unilateral tasks, decreased online corrections to perform bilateral tasks, and reduced motor impairment. These findings support the use of BAT to improve motor control and motor function of the affected upper limb in stroke patients.

    Abstract: Late-onset major depression is thought to have a biological (vascular) basis, which could be a result of brain structure change. Vascular lesions can affect both the gray matter (GM) and white matter (WM), while most previous studies addressed WM abnormality. This study explored the disease- and symptom (history of suicide attempt) -related GM morphometry in elderly male patients with late-onset depression. A total of 70 patients with depression admitted to our geriatric psychiatric ward were investigated, and 26 age-matched males were recruited as controls. We used T1-weighted magnetic resonance imaging (MRI) to obtain cerebral structural information and adopted voxel-based morphometry (VBM) to investigate brain volume change related to disease (depression vs control) and symptom (depression with history of suicide attempt vs depression without history of suicide attempt). Late-onset depression was associated with smaller volumes in several regions of GM (insula and the posterior cingulate region) and WM (subcallosal cingulate cortex, floor of lateral ventricles, parahippocampal region, insula, and the cerebellum). Compared with nonsuicidal counterpart, suicidal depression was associated with decreased GM and WM volume in the frontal, parietal, and temporal regions, and the insula, lentiform nucleus, midbrain, and the cerebellum. Marked regional volume reduction was noticed at dorsal medial prefrontal cortex. Our results demonstrate that the development of suicidal behaviors in major depression is related to widespread but discrete volume reduction in several cortical and subcortical structures, fitting with the hypothesis that decreased cerebral volume in certain regions renders biological susceptibility to attempt suicide during depressive states.

    Abstract: Some studies suggest that hospitalizations for certain conditions, called ambulatory care sensitive conditions (ACSCs), are potentially avoidable. However, almost no study has addressed the risk of ACSC hospitalizations specifically for patients with severe mental illness. Our study examines the risk of ACSC hospitalizations among patients with schizophrenia in Taiwan, using a 5-year, nationwide, population-based database. Methods: Our study included 2503 patients with schizophrenia and 20 024 matched patients without schizophrenia. Poisson regression analysis was then performed in which the number of ACSC hospitalizations from 2002 to 2006 (including ruptured appendix, asthma, cellulitis, congestive heart failure, diabetes, gangrene, hypokalemia, immunizable conditions, malignant hypertension, pneumonia, pyelonephritis, and perforated or bleeding ulcer) was regressed against the independent variable of whether or not a patient had a schizophrenia diagnosis in 2001. Results: Results show that 9.83% of patients with schizophrenia and 4.71% of patients in the comparison group experienced ACSC hospitalizations from 2002 to 2006. After adjusting for each patient's sex, age, level of urbanization, geographic location of residence within a community, and monthly income, patients with schizophrenia had a 3.26-fold higher (95% CI 3.00 to 3.54, P 〈 0.001) risk of experiencing ACSC hospitalizations than the comparison participants. After excluding the conditions of diabetes, hypertension, and asthma, patients with schizophrenia independently had a 2.46-fold higher risk of ACSC hospitalizations (95% CI 2.12 to 2.86, P 〈 0.001), compared with participants in the comparison group. Conclusions: We conclude that schizophrenia patients are at a higher risk for hospitalizations owing to ACSCs, despite a national health insurance system providing universal coverage to citizens.

    Abstract: To discuss the prevalence and associated factors related to an elevated serum alanine aminotransferase (ALT) level among the elderly agricultural and fishing population. Methods A total of 6542 (3989 males and 2553 females) healthy adults voluntarily admitted to a teaching hospital for a physical checkup in 2010 in Taipei, Taiwan. Fasting blood samples were drawn via venipuncture, and clinical nurses interviewed the study participants using a structured questionnaire from. Results The overall prevalence of an elevated serum ALT level was 18.2% and revealed a statistically significant decrease with increasing age ( P 〈 0.001). The men exhibited a higher prevalence than the women (19.7% vs 15.9%; P 〈 0.001). Male sex; younger age; and presence of obesity, hypertension, hyperuricemia, and hypoalbuminemia were significantly associated with an elevated serum ALT level. Sex-related differences were also revealed. For the men, type 2 diabetes (odds ratio [OR], 1.23; 95% confidence interval [CI] , 1.02–1.57), hypercholesterolemia (OR, 1.78; 95% CI, 1.22–2.83), hypertriglyceridemia (OR, 1.32; 95% CI, 1.04–1.73), and low high-density lipoprotein (OR, 1.26; 95% CI, 1.05–1.51) were significantly related to an elevated serum ALT level, but this was not so for the women. The disparity of ALT in age groups was revealed. Conclusion Several sex-related differences were indicated pertaining to the prevalence of an elevated serum ALT level among elderly specific occupational population.

    Abstract: This study investigates the association between social support and change in depression among older adults in Taiwan. Data are from an islandwide representative longitudinal study. The study sample includes 3,686 Taiwanese aged 50+ who completed a baseline survey and survived a 3-year follow-up period. Social support was measured by using indexes representing dimensions of tangible support, perceived emotional support, and support satisfaction. Two change in depression outcomes were constructed using a modified version of the CES-D. Results indicated that social support is a robust predictor of change in depression among those not depressed at baseline but is less consequential among those already in a state of depression. Support satisfaction is more strongly related to the outcomes than other dimensions. The discussion places the results within the Taiwanese context and provides policy implications.

    Abstract: Sleep deficit affects neurobehavioral functioning, reduces attention and cognitive function, and negatively impacts occupational safety. This study investigated selective attention levels of nursing staff on different shifts. Methods: Using a prospective, randomized parallel group study, selective attention was measured using the d2 test in 62 nursing staff in a medical center in Taiwan. Findings: There were significant differences in selective attention indicators (E%) between the fixed-day-shift group (control group) and rotating-shift group (experimental group): The percentage of errors (E%) for night-shift workers in the rotating-shift group was higher than that of fixed-day-shift workers, while the total number of items scanned minus error (TN − E) and concentration performance (CP) scores were higher for fixed-day-shift workers. Within the experimental group, the error rate on night shift was 0.44 times more than that on day shift and .62 times more than on evening shift; the TN-E on night shift was 38.99 items less than that on day shift, and the CP was 27.68 items less on night shift than on day shift; indicating that staff on the night shift demonstrated poorer speed and accuracy on the overall test than did the staff on day shifts. Conclusions: Inadequate sleep and a state of somnolence adversely affected the attention and operation speed of work among night-shift workers. More than 2 days off is suggested when shifting from the night shift to other shifts to provide adequate time for circadian rhythms to adjust.

    Abstract: To evaluate the prevalence and the association of psychological disturbance in migraine patients with allodynia. Methods We recruited 434 migraine patients from an outpatient clinic. The participants completed three self-administered questionnaires, including a headache questionnaire, an allodynia symptoms checklist, and the Hospital Anxiety and Depression Scale (HADS). Results Among the migraineurs, 48.4% participants reported allodynia. The HADS total score (15.5 ± 7.8 vs. 13.7 ± 8.5, p = 0.022) and anxiety subscore (9.1 ± 4.5 vs. 7.6 ± 4.7, p = 0.001) were higher in migraineurs with allodynia than in those without allodynia. The anxiety subscore in patients with moderate to severe allodynia, mild allodynia, and no allodynia were 10.0 ± 4.5, 8.4 ± 4.3, and 7.6 ± 4.7 ( p  〈  0.001, by one-way analysis of variance). Among patients with moderate to severe allodynia, there was a trend of higher depression subscore (7.1 ± 4.0, p = 0.059) than those with no (6.1 ± 4.4) or mild allodynia (5.8 ± 4.0). In a regression model, the presence of allodynia is an independent risk factor for clinically significant anxiety. Moderate to severe allodynia is an independent risk factor for clinically significant depression. Conclusions In migraineurs, the severity of cutaneous allodynia was associated with their mood status, especially anxiety.

    Abstract: Rolling bearing is widely used in rotating mechanical system, and its operating state has great influence on accuracy, reliability, and the life of the whole mechanical system. Therefore, fault diagnosis of rolling bearing is indispensible for the health monitoring in rotating machinery system. Wavelet package transform (WPT) and envelope demodulation have been common methods in diagnosis of bearing fault, but the precision of diagnostic results is limited by the degree of damages on bearing. In this paper, a method based on WPT and ensemble empirical mode decomposition (EEMD) is proposed to detect the fault of rolling bearing and solve this problem. According to simulation and experimental results, it is effective in fault diagnosis of rolling bearing and is better than the method based on WPT and envelope spectrum while the faults get more serious.

    Abstract: After being anastomosed with the artery, vein graft is exposed to abruptly increased hemodynamic stresses. These hemodynamic stresses may change the profile of endothelial gap junction expression as demonstrated in the artery, which may subsequently play active roles in physiological adaptation or pathophysiological changes of the vein grafts. We investigated the endothelial expression of gap junction in the venous vessels exposed to different hemodynamic stresses. Immunocytochemical analysis of the endothelial Cx expression was performed by observing the whole mounts of inferior vena cava (IVC) of aortocaval fistula (ACF) rats or IVC-banded ACF rats using confocal microscope. Immunocytochemical analysis demonstrated that in the endothelium of the native vein, the gap-junctional spot numbers (GJSNs) and the total gap-junctional areas (TGJAs) of C×40 and C×43 were lower than those of the thoracic aorta and that C×37 was hardly detectable. In the IVCs of ACF rats, which were demonstrated to be exposed to a hemodynamic condition of high flow velocity and low pressure, the GJSNs and the TGJAs of all three C×5 were increased. In the IVCs of IVC-banded ACF rats, which were exposed to a hemodynamic condition of high pressure and low flow velocity, the GJSNs and the TGJAs of C×37 increased markedly and those of C×40 and C×43 remained without significant changes. In conclusion, the endothelial expressions of gap junctions in the native veins were lower than those of the arteries. When exposed to different hemodynamic stresses, the gap junctions were expressed in specific patterns. (J Histochem Cytochem 58:1083–1092, 2010)
