Every participant was required to take the Wisconsin Card Sorting Test (WCST) and the Wechsler Adult Intelligence Scale-Revised (WAIS-R) assessments.Results: Logistic regression analysis showed the conceptual level responses (CLR) index of the WCST was the most significant index for determining intellectual disability (ID; FIQ ≤ 84). We used the receiver operating characteristic curve to determine the optimum cut-off point of CLR. The optimum one cut-off point of CLR was 66; the two cut-off points were 49 and 66. Comparing the two-stage window screening with the two-stage positive screening, the area under the curve and the positive predictive value increased. Moreover, the cost of the two-stage window screening decreased by 59%.Conclusion: The two-stage window screening is more accurate and economical than the two-stage positive screening. Our results provide an example for the use of two-stage screening and the possibility of the WCST to replace WAIS-R in large-scale screenings for ID in the future.Keywords: intellectual disability, intelligence screening, two-stage positive screening, Wisconsin Card Sorting Test, Wechsler Adult Intelligence Scale-Revise

An exploration of factors related to quality of life in Indonesian care workers in home-based care settings

Background Indonesians constituted 79% of foreign care workers for long-term care in Taiwan in 2015. Therefore, it is crucial to explore the effect of work stress and quality of life (QoL) on this population.Purpose This study aims to explore stress levels, social support requirements, and perceived QoL among Indonesian care workers (ICWs) who work in home care settings.Methods A cross-sectional design was used. Data were collected between 2014 and 2016 from a convenience sample of ICWs working in eastern Taiwan using a self-administered questionnaire that comprised the Stress Perception Scale (SPS), Social Support Scale (SSS), and World Health Organization Quality of Life-Brief scale. One hundred fifty-seven valid questionnaires were collected. The response rate was 80.51%. Data were analyzed using descriptive statistics, one-way analysis of variance, Pearson's correlation coefficient, and multiple regression analysis.Results The results found that the average SPS of the sample was 70.50, with low QoL scores and requirements for more social support. In addition, significant and positive correlations were found between QoL and SPS, SSS, duration of patient care, and hours of care per week. Stepwise regression analysis showed that the most predictive variables for QoL were time spent caring, preservice training, psychological stress, and emotional support, which together accounted for 60.9% of the total variance.Conclusions/Implications for Practice This study facilitated understanding of the stress on ICWs and the impact of social support on their QoL. The findings suggest that new immigrants in Taiwan should be introduced to foreign care workers or nursing attendants. Moreover, long-term-care-related teachers should work with home care institutions or agencies to develop a teaching model for innovative care skills to relieve the perceived stress of ICWs

Genomic sequence of temperate phage Smp131 of Stenotrophomonas maltophilia that has similar prophages in xanthomonads

Stenotrophomonas maltophilia is a ubiquitous Gram-negative bacterium previously named as Xanthomonas maltophilia. This organism is an important nosocomial pathogen associated with infections in immunocompromised patients. Clinical isolates of S. maltophilia are mostly resistant to multiple antibiotics and treatment of its infections is becoming problematic. Several virulent bacteriophages, but not temperate phage, of S. maltophilia have been characterized

Fever Screening at Airports and Imported Dengue

Airport fever screening in Taiwan, July 2003–June 2004, identified 40 confirmed dengue cases. Results obtained by capture immunoglobulin (Ig) M and IgG enzyme-linked immunoassay, real time 1-step polymerase chain reaction, and virus isolation showed that 33 (82.5%) of 40 patients were viremic. Airport fever screening can thus quickly identify imported dengue cases

Vertically-aligned graphene nanowalls grown via plasma-enhanced chemical vapor deposition as a binder-free cathode in Li-O_2 batteries

In the present report, vertically-aligned graphene nanowalls are grown on Ni foam (VA-G/NF) using plasma-enhanced chemical vapor deposition method at room temperature. Optimization of the growth conditions provides graphene sheets with controlled defect sites. The unique architecture of the vertically-aligned graphene sheets allows sufficient space for the ionic movement within the sheets and hence enhancing the catalytic activity. Further modification with ruthenium nanoparticles (Ru NPs) drop-casted on VA-G/NF improves the charge overpotential for lithium–oxygen (Li–O_2) battery cycles. Such reduction we believe is due to the easier passage of ions between the perpendicularly standing graphene sheets thereby providing ionic channels

The Induction of Apoptosis by SV40 T Antigen Correlates with c-junOverexpression

AbstractSimian virus (SV40) T antigen shares many characteristics with adenovirus E1A which is known to induce apoptosis. To verify the potential of SV40 T antigen-mediated apoptosis, we stably expressed T antigen in immortalized human epithelial cells (Z172 and HaCaT). We found that SV40 T antigen could directly cause apoptosis in 22–27% of these cells under normal growth condition as measured by chromatin condensation and nucleosomal fragmentation. The apoptosis of HaCaT cells which contain mutant p53 suggests the p53-independent nature of T antigen-mediated apoptosis. T antigen-induced apoptosis was associated with increased expression of c-Jun protein. Moreover, the overexpression of c-junalone in these cells also induced apoptosis, indicating that c-junmight play an important role in T antigen-induced apoptosis
