RESUMO

Background: Apolipoprotein E (APOE) is the strongest genetic risk factor for sporadic Alzheimer's Disease (AD), and the ε4 allele (APOE4) may interact with lifestyle factors that relate to brain structural changes, underlying the increased risk of AD. However, the exact role of APOE4 in mediating interactions between the peripheral circulatory system and the central nervous system, and how it may link to brain and cognitive aging requires further elucidation. In this analysis, we investigated the association between APOE4 carrier status and multimodal biomarkers (diet, blood markers, clinical diagnosis, brain structure, and cognition) in the context of gene-environment interactions. Methods: Participants were older adults from a longitudinal observational study, the Boston Puerto Rican Health Study (BPRHS), who self-identified as of Puerto Rican descent. Demographics, APOE genotype, diet, blood, and clinical data were collected at baseline and at approximately 12th year, with the addition of multimodal brain magnetic resonance imaging (MRI) (T1-weighted and diffusion) and cognitive testing acquired at 12-year. Measures were compared between APOE4 carriers and non-carriers, and associations between multimodal variables were examined using correlation and multivariate network analyses within each group. Results: A total of 156 BPRHS participants (mean age at imaging = 68 years, 77% female, mean follow-up 12.7 years) with complete multimodal data were included in the current analysis. APOE4 carriers (n = 43) showed reduced medial temporal lobe (MTL) white matter (WM) microstructural integrity and lower mini-mental state examination (MMSE) score than non-carriers (n = 113). This pattern was consistent with an independent sample from the Alzheimer's Disease Neuroimaging Initiative (ADNI) of n = 283 non-Hispanic White adults without dementia (mean age = 75, 40% female). Within BPRHS, carriers showed distinct connectivity patterns between multimodal biomarkers, characterized by stronger direct network connections between baseline diet/blood markers with 12-year blood/clinical measures, and between blood markers (especially lipids and cytokines) and WM. Cardiovascular burden (i.e., hypertension and diabetes status) was associated with WM integrity for both carriers and non-carriers. Conclusion: APOE4 carrier status affects interactions between dietary factors, multimodal blood biomarkers, and MTL WM integrity across ~12 years of follow-up, which may reflect increased peripheral-central systems crosstalk following blood-brain barrier breakdown in carriers.

RESUMO

The application of artificial intelligence (AI) to summarize a whole-brain magnetic resonance image (MRI) into an effective "brain age" metric can provide a holistic, individualized, and objective view of how the brain interacts with various factors (e.g., genetics and lifestyle) during aging. Brain age predictions using deep learning (DL) have been widely used to quantify the developmental status of human brains, but their wider application to serve biomedical purposes is under criticism for requiring large samples and complicated interpretability. Animal models, i.e., rhesus monkeys, have offered a unique lens to understand the human brain - being a species in which aging patterns are similar, for which environmental and lifestyle factors are more readily controlled. However, applying DL methods in animal models suffers from data insufficiency as the availability of animal brain MRIs is limited compared to many thousands of human MRIs. We showed that transfer learning can mitigate the sample size problem, where transferring the pre-trained AI models from 8,859 human brain MRIs improved monkey brain age estimation accuracy and stability. The highest accuracy and stability occurred when transferring the 3D ResNet [mean absolute error (MAE) = 1.83 years] and the 2D global-local transformer (MAE = 1.92 years) models. Our models identified the frontal white matter as the most important feature for monkey brain age predictions, which is consistent with previous histological findings. This first DL-based, anatomically interpretable, and adaptive brain age estimator could broaden the application of AI techniques to various animal or disease samples and widen opportunities for research in non-human primate brains across the lifespan.

RESUMO

INTRODUCTION: This study provides long-term evidence that profiles of temperament during adolescence are associated with happiness and health over two decades later. METHODS: Data are based on the ongoing Fullerton Longitudinal Study, a community-based sample in the United States. At 14 and 16 years, adolescents (N = 111; 52% male, 90% Euro-American) and their mothers (N = 105) completed the Dimensions of Temperament Survey-Revised, a scale designed specifically to assess adolescents' temperament across a set of attributes. When adolescents reached age 38 years in 2017, they completed scales measuring comprehensive happiness and global health. RESULTS: Latent profile analysis (LPA), a person-centered approach, was conducted for adolescents' and for mothers' temperament ratings separately. Distinct two-profile solutions, labeled more regulated and less regulated, emerged for each informant. These were comparable in features across informants. Only the adolescents' self-rated profiles, controlling for sex and family SES, revealed a conceptually meaningful and statistically significant relation to the distal outcomes of health and happiness two decades later. CONCLUSIONS: Adolescents with temperament profiles characterized as more regulated, in contrast to less regulated, reported being happier and healthier upon entering middle adulthood. Implications for intervention are presented.

RESUMO

Objective: The beginning of college marks a decline in physical activity and racial/ethnic minorities have disproportionately lower rates of physical activity. This study examined the association between perceived stress and physical activity among an ethnically diverse sample of college-attending young adults. Participants: 2,396 students (36% male, 64% female) from a large public university. Methods: Cross-sectional survey administered across campus departments and general education courses. Results: Gender stratified multivariate analyses showed for both males and females, higher perceived stress was associated with less frequency of physical activity the past six months. Compared to non-Hispanic white females, Hispanic/Latina females and Asian/Pacific Islander females reported significantly less frequency of vigorous/moderate and strengthening/toning activities. There were no race/ethnic differences among males. Conclusions: These findings highlight the need to create targeted interventions for college men and women and among racial/ethnic subgroups.

RESUMO

BACKGROUND: Patients with dementia often present agitated behaviors. The Cohen-Mansfield Agitation Inventory-short form (CMAI-SF) is one of the most widely used instruments to evaluate agitated behaviors that affect patients' quality of life and impose burden on caregivers. However, there is no simplified Chinese version of the CMAI-SF (C-CMAI-SF) in clinical settings. PURPOSE: This study aimed to develop a Chinese version of the C-CMAI-SF and examine its validity and reliability. METHODS: This cross-sectional study included three phases. In Phase I, the original CMAI-SF was translated to Chinese. In Phase II, experts were invited to examine the content validity index (CVI). Phase III was conducted to test the validity and reliability of the C-CMAI-SF. RESULTS: The scale showed good validity and reliability with a scale-level CVI of 0.89, Cronbach's alpha (measure of internal consistency) of 0.874, and test-retest correlation coefficient of 0.902 (for 257 individuals). Using factor analysis, three factors were identified. Regarding concurrent validity, the C-CMAI-SF score was correlated with the Neuropsychiatric Inventory (agitation aggression subscale) and the Cornell Scale for Depression in Dementia (agitation subscale). CONCLUSIONS: The study demonstrated that the C-CMAI-SF is a valid and reliable instrument for evaluating agitated behaviors in people with dementia. RELEVANCE TO CLINICAL PRACTICE: The C-CMAI-SF is an easy and quick tool used to identify and evaluate agitated behaviors in busy clinical settings.

RESUMO

BACKGROUND AND OBJECTIVES: The Boston Puerto Rican Health Study (BPRHS) is a longitudinal study following self-identified Puerto Rican older adults living in the Greater Boston area. Studies have shown higher prevalence of hypertension (HTN) and type 2 diabetes (T2D) within this ethnic group compared to age-matched non-Hispanic White adults. In this study, we investigated the associations of HTN and T2D comorbidity on brain structural integrity and cognitive capacity in community-dwelling Puerto Rican adults and compared these measures with older adult participants (non-Hispanic White and Hispanic) from the Alzheimer's Disease Neuroimaging Initiative (ADNI) and National Alzheimer's Coordinating Center (NACC) databases. METHODS: BPRHS participants who underwent brain MRI and cognitive testing were divided into 4 groups based on their HTN and T2D status: HTN-/T2D-, HTN+/T2D-, HTN-/T2D+, and HTN+/T2D+. We assessed microstructural integrity of white matter (WM) pathways using diffusion MRI, brain macrostructural integrity using hippocampal volumes, and brain age using T1-weighted MRI and cognitive test scores. BPRHS results were then compared with results from non-Hispanic White and Hispanic participants from the ADNI and NACC databases. RESULTS: The prevalence of HTN was almost 2 times (66.7% vs 38.7%) and of T2D was 5 times (31.8% vs 6.6.%) higher in BPRHS than in ADNI non-Hispanic White participants. Diffusion MRI showed clear deterioration patterns in major WM tracts in the HTN+/T2D+ group and, to a lesser extent, in the HTN+/T2D- group compared to the HTN-/T2D- group. HTN+/T2D+ participants also had the smallest hippocampal volume and larger brain aging deviations. Trends toward lower executive function and global cognitive scores were observed in HTN+/T2D+ relative to HTN-/T2D- individuals. MRI measures and the Mini-Mental State Examination (MMSE) scores from the HTN+/T2D+ BPRHS group resembled those of ADNI White participants with progressive mild cognitive impairment (MCI), while the BPRHS HTN-/T2D- participants resembled participants with stable MCI. The BPRHS was not significantly different from the ADNI + NACC Hispanic cohort on imaging or MMSE measures. DISCUSSION: The effects of T2D and HTN comorbidity led to greater brain structural disruptions than HTN alone. The high prevalence of HTN and T2D in the Puerto Rican population may be a key factor contributing to health disparities in cognitive impairment in this group compared to non-Hispanic White adults in the same age range.

RESUMO

In this prospective study, we examined the link between positive family relationships during childhood and adolescence and health and happiness three decades later in middle adulthood. We also investigated the stability of positive family relationships into adulthood as one possible pathway underlying this long-term association. Data were from the Fullerton Longitudinal Study (FLS) an ongoing investigation in the United States initiated in 1979 when children were aged 1 year with the most recent data collected in 2017. A cross-informant methodology was employed in which mothers and children independently completed the Positive Family Relationships (PFR) scale annually when children were of ages 9-17 years. When study children reached age 38, they reported on their current PFR, global health, and comprehensive happiness. Structural equation models revealed that children's perceptions of the family during childhood and adolescence predicted both their health and happiness at age 38. Mothers' perspectives of PFR predicted greater adult children's health, but did not predict their happiness. Associations were independent of family socioeconomic status, gender, intelligence, and extraversion. Moreover, while controlling for behavior problems (proxy for health) and happiness at age 17, both children's and mothers' early PFR related to PFR at 38 years, which in turn, predicted increased health and happiness at age 38, thus providing evidence for a pathway underlying this long-term connection. Our prospective findings revealed that families in which members get along well and support each other during the childhood and adolescent years furnish a foundation for positive family relationships in adulthood, which are associated with greater health and happiness.

RESUMO

Objective: The growing prevalence of obesity among college students is a major public health issue, as over one-third are overweight or obese. This study used gender-stratified multivariate analyses to examine psychological distress and social contextual factors as key determinants of obesity. Participants: Students of a large public university in Southern California (N = 2392). Methods: In-class survey administered across various departments and general education courses. Results: Among females, distress (OR = 1.02) and sophomores (OR = 1.87) were associated with increased odds of obesity; Greek life (OR = 0.53) was associated with decreased odds of obesity. Among males, distress was not associated with obesity (OR = 1.00); financial strain (OR = 1.16) was associated with increased odds of obesity. Conclusions: There are gendered patterns in obesity risk with social context having potentially protective effects among women. Enhancing psychological wellbeing as well as creating gender- and context-specific interventions may be an effective strategy to address the rising rates of obesity among the college population.

RESUMO

About a third of all United States veterans who served in the 1991 Gulf War (GW) report a range of chronic health symptoms including fatigue, neurocognitive symptoms, and musculoskeletal pain. There is growing evidence supporting the detrimental effects of maladaptive neuroimmune reactions in this multi-symptom illness. Indeed, recent studies using positron emission tomography (PET) using the radioligand [11C]PBR28, which binds the neuroinflammation marker 18 â€‹kDa translocator protein (TSPO), and diffusion magnetic resonance imaging (dMRI) have independently identified the anterior cingulate (ACC) and midcingulate cortices (MCC) as key regions for differentiating GWI veterans from healthy controls (HC). Here, we used integrated (i.e., simultaneous) PET/MRI imaging techniques, paired with dMRI processing methods (neurite density imaging, NDI, and free-water diffusion tensor model to single-shell high-order dMRI), to directly evaluate the relationship between ACC and MCC microstructural tissue parameters, TSPO signal and clinical parameters in the same cohorts of 10 GWI veterans and 19 â€‹HCs. Within the regions evaluated, TSPO signal elevations were associated with restricted diffusivity in the extracellular compartment, while clinical measures were best explained by neurite density and cellular structure complexity measures. Our study is the first to provide evidence of a relationship between PET and dMRI modalities in GWI and suggests that microstructural changes in the ACC and MCC are correlated to mood symptoms and cognitive performances in GWI veterans.

RESUMO

BACKGROUND AND OBJECTIVE: To deal with burn mass casualty incidents (BMCIs), various countries have established national or regional BMCI emergency response plans (ERPs). A burn care capacity ranking model for hospitals can play an integral role in ERPs by providing essential information to emergency medical services for distributing and handling mass burn patients. Ranking models vary across countries and contexts. However, Taiwan has had no such model. The study aims to develop a ranking model for classifying hospitals' burn care capacity in preparation for the development of a national BMCI ERP. METHODS: Multiple methods were adopted. An expert panel provided consultations on data selection and clustering validation. Data on 116 variables from 535 hospitals were collected via open data platforms under the Ministry of Health and Welfare. Data selection and streamlining was conducted to determine 42 variables for cluster analysis. SAS 9.4 was used to analyze the data set -via a hierarchical cluster analysis using Ward's method, followed by a tree-based model analysis to identify the criteria for each cluster. Both internal and external cluster validation were performed. RESULTS: Four clusters of burn care capacity were determined to be a suitable number of clusters. All hospitals were arranged into capacity levels accordingly. Results of the Kruskal-Wallis test showed that the difference between clusters were significant. Tree-based model analysis revealed four determining variables, among which the refined level of emergency care responsibility hospital was found to be most influential on the clustering process. Responses from the questionnaire were used as an external validation tool to corroborate with the cluster analysis results. CONCLUSION: The use of open government data and cluster analysis was suitable for developing a ranking model to determine hospitals' burn care capacity levels in Taiwan. The proposed ranking model can be used to develop a BMCI emergency response plan and can also serve as a reference for using cluster analysis with open government data to rank care capacity or quality in other domains.

RESUMO

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) enters the cells through the binding of its spike protein (S-protein) to the cell surface-expressing angiotensin-converting enzyme 2 (ACE2). Thus, inhibition of S-protein-ACE2 binding may impede SARS-CoV-2 cell entry and attenuate the progression of Coronavirus disease 2019 (COVID-19). In this study, an electrochemical impedance spectroscopy-based biosensing platform consisting of a recombinant ACE2-coated palladium nano-thin-film electrode as the core sensing element was fabricated for the screening of potential inhibitors against S-protein-ACE2 binding. The platform could detect interference of small analytes against S-protein-ACE2 binding at low analyte concentration and small volume (0.1 µg/mL and ~1 µL, estimated total analyte consumption < 4 pg) within 21 min. Thus, a few potential inhibitors of S-protein-ACE2 binding were identified. This includes (2S,3aS,6aS)-1-((S)-N-((S)-1-Carboxy-3-phenylpropyl)alanyl)tetrahydrocyclopenta[b] pyrrole-2-carboxylic acid (ramiprilat) and (2S,3aS,7aS)-1-[(2S)-2-[[(2S)-1-Carboxybutyl]amino]propanoyl]-2,3,3a,4,5,6,7,7a-octahydroindole-2-carboxylic acid (perindoprilat) that reduced the binding affinity of S-protein to ACE2 by 72% and 67%; and SARS-CoV-2 in vitro infectivity to the ACE2-expressing human oral cavity squamous carcinoma cells (OEC-M1) by 36.4 and 20.1%, respectively, compared to the PBS control. These findings demonstrated the usefulness of the developed biosensing platform for the rapid screening of modulators for S-protein-ACE2 binding.

RESUMO

Gulf War illness (GWI) refers to the multitude of chronic health symptoms, spanning from fatigue, musculoskeletal pain, and neurological complaints to respiratory, gastrointestinal, and dermatologic symptoms experienced by about 250,000 GW veterans who served in the 1991 Gulf War (GW). Longitudinal studies showed that the severity of these symptoms often remain unchanged even years after the GW, and these veterans with GWI continue to have poorer general health and increased chronic medical conditions than their non-deployed counterparts. For better management and treatment of this condition, there is an urgent need for developing objective biomarkers that can help with simple and accurate diagnosis of GWI. In this study, we applied multiple neuroimaging techniques, including T1-weighted magnetic resonance imaging (T1W-MRI), diffusion tensor imaging (DTI), and novel neurite density imaging (NDI) to perform both a group-level statistical comparison and a single-subject level machine learning (ML) analysis to identify diagnostic imaging features of GWI. Our results supported NDI as the most sensitive in defining GWI characteristics. In particular, our classifier trained with white matter NDI features achieved an accuracy of 90% and F-score of 0.941 for classifying GWI cases from controls after the cross-validation. These results are consistent with our previous study which suggests that NDI measures are sensitive to the microstructural and macrostructural changes in the brain of veterans with GWI, which can be valuable for designing better diagnosis method and treatment efficacy studies.

RESUMO

The complex etiology behind Gulf War Illness (GWI) has been attributed to the combined exposure to neurotoxicant chemicals, brain injuries, and some combat experiences. Chronic GWI symptoms have been shown to be associated with intensified neuroinflammatory responses in animal and human studies. To investigate the neuroinflammatory responses and potential causes in Gulf War (GW) veterans, we focused on the effects of chemical/biological weapons (CBW) exposure and mild traumatic brain injury (mTBI) during the war. We applied a novel MRI diffusion processing method, Neurite density imaging (NDI), on high-order diffusion imaging to estimate microstructural alterations of brain imaging in Gulf War veterans with and without GWI, and collected plasma proinflammatory cytokine samples as well as self-reported health symptom scores. Our study identified microstructural changes specific to GWI in the frontal and limbic regions due to CBW and mTBI, and further showed distinctive microstructural patterns such that widespread changes were associated with CBW and more focal changes on diffusion imaging were observed in GW veterans with an mTBI during the war. In addition, microstructural alterations on brain imaging correlated with upregulated blood proinflammatory cytokine markers TNFRI and TNFRII and with worse outcomes on self-reported symptom measures for fatigue and sleep functioning. Taken together, these results suggest TNF signaling mediated inflammation affects frontal and limbic regions of the brain, which may contribute to the fatigue and sleep symptoms of the disease and suggest a strong neuroinflammatory component to GWI. These results also suggest exposures to chemical weapons and mTBI during the war are associated with different patterns of peripheral and central inflammation and highlight the brain regions vulnerable to further subtle microscale morphological changes and chronic signaling to nearby glia.

RESUMO

EMR2/ADGRE2 is a human myeloid-restricted adhesion G protein-coupled receptor critically implicated in vibratory urticaria, a rare type of allergy caused by vibration-induced mast cell activation. In addition, EMR2 is also highly expressed by monocyte/macrophages and has been linked to neutrophil migration and activation. Despite these findings, little is known of EMR2-mediated signaling and its role in myeloid biology. In this report, we show that activation of EMR2 via a receptor-specific monoclonal antibody promotes the differentiation of human THP-1 monocytic cell line and induces the expression of pro-inflammatory mediators, including IL-8, TNF-α, and MMP-9. Using specific signaling inhibitors and siRNA knockdowns, biochemical and functional analyses reveal that the EMR2-mediated signaling is initiated by Gα16, followed by the subsequent activation of Akt, extracellular signal-regulated kinase, c-Jun N-terminal kinase, and nuclear factor kappa-light-chain-enhancer of activated B cells. Our results demonstrate a functional role for EMR2 in the differentiation and inflammatory activation of human monocytic cells and provide potential targets for myeloid cell-mediated inflammatory disorders.

RESUMO

BACKGROUND: Prior studies indicate that the perception of nursing image heldx by nursing students influences the attitudes of these students toward nursing care and their future professional role identity as nurses. However, few studies have investigated this issue in Taiwan in recent years. PURPOSE: To examine the perceptions of nursing image held by third- and fourth-year baccalaureate nursing students and the factors that influence these perceptions. METHODS: The present study employed a cross-sectional survey design. Questionnaires were administered to a total of 219 nursing students who were currently enrolled at a university in southern Taiwan. Descriptive statistics, chi-square test, Pearson product-moment correlation, multiple linear regression, and simple logistic regression analysis were conducted using SPSS 12.0, Chinese version. RESULTS: The mean age of participants was 22.2 years; most were fourth-year students (58.9%) and female (85.8%). Regarding the images of nursing, most participants indicated that current nursing work possesses characteristics that include: "being a profession", "emphasizing care and concern for patients", "requiring meticulousness", and "requiring emotional control". In terms of perceptions of professional nurses, most participants considered nurses to be: "constantly needing to progress and innovate", "capable of caring for and respecting others", "independent and self-conscious", and "sufficiently intelligent". The present study identified significant differences between third- and fourth-year students in only three variables, with a larger percentage of fourth-year students perceiving nurses as "dedicated and willing to sacrifice", "handmaidens to doctors", and "not bossy and stern" than their third-year peers. In addition, it demonstrated significantly positive relationships between the dependent variables of traditional/bureaucratic image and advanced professional image and the independent variables of willingness to become nursing professionals after graduation, satisfaction with the school's clinical courses arrangement, and learning-environmental factors. Furthermore, "more job opportunities", as a reason for admission to nursing school and learning-environmental factors, explained 11.7% of the variance in participant perceptions of traditional/bureaucratic image and "encouragement from family and friends", as a reason for admission to nursing school and learning-environmental factors, explained 18.2% of the variance in participant perceptions of advanced professional image. Finally, both "traditional/bureaucratic image" and "advanced professional image" were predictors of participant willingness to become nursing professional after graduation. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The results of the study may be referenced by nursing educators, nursing administrators, and nursing policy makers.

RESUMO

The Philippines is one of seven countries in which HIV incidence has recently increased-much of this increase has been among men who have sex with men. Despite this trend, knowledge on sexuality and same-sex behaviors in the Philippines is limited. This study examines same-sex behavior, sexual outcomes, substance use, and psychological distress among young adults participating in the 2005 Cebu Longitudinal Health and Nutrition Survey (CLHNS). We use gender-stratified, multivariate models to compare young adults who reported same-sex behaviors and those who did not. Among a cohort of 1,912 Filipino young adults (ages 20-22), 58.2 % were sexually experienced and 15.1 % of them reported same-sex sexual contacts or romantic relationships. Compared to females, more males reported same-sex sexual contact (19.4 vs. 2.3 %) or same-sex romantic relationships (9.2 vs. 4.1 %). Young adults reporting same-sex behavior had higher odds of smoking, drug use, perceived stress, and more sexual partners as compared to their peers. Males who reported same-sex behavior initiated sex earlier than those males who did not report same-sex behaviors. There were no significant differences in depressive distress. Earlier sexual initiation and higher levels of substance use among Filipino young adults engaging in same-sex behavior highlight the need to address unique health issues within this population. Mixed findings for depressive distress and perceived stress indicate that further investigation is needed to explore the potential impacts of same-sex status on mental health outcomes, particularly in lower- and middle-income countries such as the Philippines.

RESUMO

Social comparison refers to self-evaluation against other people. When people are outperformed by peers in a domain relevant (irrelevant) to them, it negatively (positively) affects how they evaluate themselves, compared to an irrelevant (relevant) domain. Whether a domain is self-relevant or self-irrelevant, the comparison direction and closeness should interact on how people evaluate themselves. Taiwanese undergraduates (N = 276) ages 19 to 22 years (M = 20.5, SD = 1.8), participated to assess whether the results from Western samples would be similar to those in an Asian sample, which were expected to be more collectivist.

RESUMO

The main purpose of this study is to investigate the impact of service quality and corporate social responsibility (CSR) on customer satisfaction, and customer satisfaction toward post-purchase intentions from sheltered employment institutions. Work experience plays an important role in career development for those people with intellectual disabilities. When they are not yet capable of obtaining a job in the open market, they must receive job training and daily care in sheltered employment institutions. If the sheltered employment institutions cannot operate properly, they will greatly affect intellectual disabilities. From the study of "Children Are Us Bakeries and Restaurants" sheltered employment institutions are one kind of food service business that has been found to request and improve service quality and execution of CSR. These are two main factors which can enhance brand value and create a good reputation for sheltered employment institutions. The questionnaire results indicate that perceived service quality has a positive relationship with customer satisfaction and the reliability dimension is the most important factor for customers to assess service quality. Meanwhile, correlation analysis shows that customer satisfaction regarding service quality influences post-purchase intentions, indicating that friendly and helpful employees can please customers and enhance their satisfaction level and also induce positive post-purchase intentions of consumers. Regarding the CSR of "Children Are Us Bakeries and Restaurants" sheltered employment institutions, the analysis reveals a statistical significance: the greater customer satisfaction of CSR, the higher the post-purchase intention. In addition, in the work, paired-sample t test analysis reveals there is a significant difference (p<.05) in service quality and CSR in terms of "perceived" and "expected" responses. In summary, since those with intellectual disabilities usually are enthusiastic at work and do their best to provide good service and execute CSR well, the value of sheltered employment institutions establishments should be recognized by all should receive continued support and there should be a willingness to hire these intellectually disabled citizens.

RESUMO

We report two cases of imported infection in patients who had returned to Taiwan from Singapore: one was coinfected with chikungunya virus and dengue virus type 2, and the other was infected with the same dengue virus. Both viruses were successfully isolated from the coinfected case by using antibody neutralization and a plaque purification technique.
