RESUMO

This study aimed to assess the efficacy of a guided online mindfulness-based intervention (iMBI) for community residents experiencing emotional distress during the COVID-19 pandemic in Hong Kong. In a randomized controlled trial, 64 participants were recruited from collaborating community-based mental health service units in Hong Kong and assigned to either the treatment (n = 32) or control (n = 32) groups. The treatment group received a guided iMBI consisting of 16 online modules, weekly telephone counseling, and two half-day online workshops on mindfulness practice. In contrast, the waitlist control group did not receive any intervention during the initial stage. Using a 2 (two groups) × time (pre versus post) repeated measures linear mixed model and one-way analysis of variance, authors demonstrated that the treatment group experienced a significantly larger reduction in anxiety and depressive symptoms with a large effect size compared with the control group. Additionally, the treatment group showed a significantly greater improvement in mindfulness with a moderate effect size. The findings support the effectiveness of guided iMBI for community residents experiencing emotional distress during the COVID-19 pandemic in Hong Kong.

RESUMO

Objective: This study investigated the effectiveness of a low-intensity online mindfulness-based Intervention (iMBI) for alleviating anxiety in university students during the COVID-19 pandemic. Methods: In a randomized controlled trial involving 134 participants from a local university in Hong Kong, subjects were randomly assigned to either the intervention group (n = 67) or the inactive control group (n = 67). The intervention group participated in a low-intensity iMBI comprising 16 online modules and two half-day online mindfulness workshops over an eight-week period. Outcomes were measured via an online platform using standardized assessment scales, including the Beck Anxiety Inventory and the Chinese Five Facets Mindfulness Questionnaire, at three different time points: pre-intervention, post-intervention and at a three-month follow-up. Results: Intent-to-treat analysis using 2 (group) × 3 (time) repeated measures of covariance (ANCOVA) showed that the intervention group, compared to the control group, showed a significant reduction in anxiety symptoms with a medium effect size (Cohen's d = 0.5) and a significant improvement in mindfulness skills with a medium effect size (Cohen's d = 0.5) at post-intervention. The effects of the intervention in reducing anxiety and improving mindfulness persisted at the three-month follow-up. Conclusion: The results of this study demonstrate the effectiveness of the low-intensity iMBI in alleviating anxiety among university students.

RESUMO

Mutations in SARS-CoV-2 raised concerns about diminishing vaccine effectiveness against COVID-19 caused by particular variants. Even with high initial efficacy, if a vaccines efficacy drops significantly against variants, or if it cannot be distributed quickly, it is uncertain whether the vaccine can provide better health outcomes than other vaccines. Hence, we evaluated the trade-offs between the speed of distribution vs. efficacy against infection of multiple vaccines when variants emerge by utilizing a Susceptible-Infected-Recovered-Deceased (SIR-D) model and assessing the level of infection attack rate (IAR). Our results show that speed is a key factor to a successful immunization strategy to control the COVID-19 pandemic even when the emerging variants may reduce the efficacy of a vaccine. Due to supply-chain challenges, the accessibility and distribution of the vaccines have been hindered in many regions, especially in low-income countries, while the second or third wave of the pandemic has occurred due to the variants. Understanding the tradeoffs between speed and efficacy and distributing vaccines that are available as quickly as possible are crucial to eradicate the pandemic before new variants spread.

RESUMO

BackgroundTo date, there has been limited data available to understand the associations between race/ethnicity and socioeconomic and related characteristics with novel coronavirus disease (COVID-19) vaccine initiation and planned vaccination in the United States. MethodsTo better characterize COVID-19 vaccinations nationally, we leveraged large cross-sectional surveys conducted between January and March 2021 with relatively complete race/ethnicity and socioeconomic data and nationally-representative of U.S. households to estimate trends in levels of COVID-19 vaccine initiation and vaccine intention. We further used survey data from January and March 2021 in adults aged 18-85 years to analyze the associations between race/ethnicity, education, pre-pandemic household income, and financial hardship during the pandemic and the adjusted odds of: 1) receipt of [≥]1 dose of a COVID-19 vaccine; and 2) among those unvaccinated, the definite intention to receive a vaccine, controlling for other demographic and socioeconomic factors. ResultsWe observed persistent disparities in vaccine initiation for non-Hispanic Blacks, Hispanics, and non-Hispanic multiracial persons, and in vaccine intention for Blacks and multiracial persons, compared to non-Hispanic Whites and non-Hispanic Asians. In late March 2021, the prevalence estimates of Hispanics and Blacks receiving a vaccine were 12 percentage points and 8 percentage points lower than for Whites, respectively. Moreover, both education and income levels exhibited positive dose-response relationships with vaccine initiation (P for trend[≤]01 and <.001, respectively). Substantial financial hardship was linked to 35-44% lower odds of vaccination (P<.001). The most common reasons for vaccine hesitancy were concerns about side effects and safety, with evidence of higher levels of concerns about vaccine safety among Blacks vs. Whites. ConclusionsIn this large, nationally-representative study with relatively complete race/ethnicity and socioeconomic data, we find that being Black non-Hispanic and having the least education and income were each independently associated with a markedly lower likelihood of definitely planning to get vaccinated or having been vaccinated. In the ensuing months of the pandemic, addressing the persevering racial/ethnic and socioeconomic inequities in vaccination due to differential access and vaccine hesitancy is essential to mitigate the pandemics higher risks of infection and adverse health outcomes in Hispanic, Black, and socioeconomically-disadvantaged communities.

RESUMO

ObjectiveVaccine shortage and supply-chain challenges have caused limited access by many resource-limited countries during the COVID-19 pandemic. One of the primary decisions for a vaccine-ordering decision-maker is how to allocate the limited resources between different types of vaccines effectively. We studied the tradeoff between efficacy and reach of the two vaccine types that become available at different times. MethodsWe extended a Susceptible-Infected-Recovered-Deceased (SIR-D) model with vaccination, ran extensive simulations with different settings, and compared the level of infection attack rate (IAR) under different reach ratios between two vaccine types under different resource allocation decisions. ResultsWe found that when there were limited resources, allocating resources to a vaccine with high efficacy that became available earlier than a vaccine with lower efficacy did not always lead to a lower IAR, particularly if the former could vaccinate less than 42.5% of the population (with the selected study parameters) who could have received the latter. Sensitivity analyses showed that this result stayed robust under different study parameters. ConclusionsOur results showed that a vaccine with lower resource requirements (wider reach) can significantly contribute to reducing IAR, even if it becomes available later in the pandemic, compared to a higher efficacy vaccine that becomes available earlier but requires more resources. Limited resource in vaccine distribution is significant challenge in many parts of the world that needs to be addressed to improve the global access to life-saving vaccines. Understanding the tradeoffs between efficacy and reach is critical for resource allocation decisions between different vaccine types for improving health outcomes.

RESUMO

BackgroundWhile social assistance through the United States (U.S.) federal Coronavirus Aid, Relief, and Economic Security (CARES) Act provided expanded unemployment insurance benefits during the coronavirus disease 2019 (COVID-19) pandemic until the summer of 2020, it is unclear whether subsequent social assistance has been or will be sufficient to meet everyday spending needs and to curb the adverse health-related sequelae of financial hardship. MethodsThis study estimated recent trends in financial hardship among working-aged Americans with job-related income loss during the pandemic. It also used multivariable logistic regression and repeated cross-sectional individual-level U.S. Household Pulse Survey data on 91,222 working-aged adults between September and December 2020 to explore the associations of financial hardship with mental health outcomes and food and housing insecurity after accounting for receipt of social assistance. ResultsExperiencing somewhat of a financial hardship (vs no hardship) was linked to 3-7 times higher odds of anxiety and depressive symptoms and a likely eviction, and 11 times higher odds of food insufficiency. Experiencing considerable financial hardship (vs no hardship) predicted 5-7 fold higher odds of anxiety and depressive symptoms, 34-fold higher odds of a likely housing eviction, and 37-fold higher odds of food insufficiency (all P values <.001). Across outcomes, these relationships were stronger at each successively higher level of financial hardship (all P values for linear trend <.001), and more than offset any corresponding benefits from social assistance. ConclusionsEven after accounting for receipt of social assistance, working-aged adults experiencing financial hardship had markedly greater odds of anxiety and depressive symptoms, food insufficiency, and an anticipated housing eviction. These findings point to the urgent need for direct and sustained cash relief well in excess of current levels of social assistance, and provide a critical baseline assessment for evaluating the impacts of federal public policy responses to economic hardships during the pandemic. It is essential that the U.S. Congress and the new Biden administration provide adequate and needs-based social policy relief measures in order to mitigate the pandemics adverse impacts on the physical, mental, and social well-being of millions of Americans.

RESUMO

OBJECTIVE: This research study aims to evaluate the effectiveness of a multicomponent intervention that combines a cognitive stimulation group and tai chi to reduce cognitive decline among community-dwelling Chinese older adults with probable dementia. METHODS: A multi-center, randomized controlled trial design was adopted in this study. In addition to treat as usual, the treatment group (n = 41) participated in a structured cognitive stimulation group followed by tai chi twice a week, with a total of 14 sessions held during the study period. The control group (n = 39) received treat as usual. Mattis Dementia Rating Scale and Mini-Mental State Examination were used for assessing the cognitive abilities of participants in the pre- and post-treatment periods. RESULTS: A 2 × 2 repeated measures analysis of covariance demonstrated that the treatment group was more effective than the control group on improving Dementia Rating Scale score (F = 7.45, p < .01) with a moderate effect size (partial eta square = .09) and Mini-Mental State Examination score (F = 9.96, p < .01) with a moderate to large effect size (partial eta square = .12) after controlling for age, gender, educational level, marital status, and number of physical illnesses. CONCLUSION: The present study demonstrates the effectiveness of the multicomponent intervention on improving cognitive ability among community-dwelling older adults with probable dementia, suggesting that the multicomponent intervention can facilitate early identification, assessment, and treatment for community-dwelling older adults with probable dementia.

RESUMO

OBJECTIVE: This research study aims to evaluate the effectiveness of an expanded cognitive stimulation therapy (CST) model that combines a CST group and tai chi on improving the cognitive ability of community-dwelling Chinese elderly with mild stage dementia (EwMD). METHOD: A randomized waitlist controlled trial design was adopted in this study. The treatment group participated in a structured CST group followed by tai chi twice a week, with a total of 14 sessions throughout the study period. The waitlist control group received treatment as usual at the initial stage and expanded CST model at a later stage. The Chinese Mattis Dementia Rating Scale (DRS) and the Chinese Mini Mental State Examination (MMSE) were used to assess the cognitive ability of EwMD in the pre- and post- treatment periods. RESULTS: At baseline, the treatment group (n = 51) and control group (n = 50) did not differ significantly in any demographic or clinical variables. Overall, the participants had a mean baseline MMSE score of 20.67 (SD = 2.30). The 2 × 2 repeated measures ANCOVA demonstrated that the treatment group was significantly more effective than the control group in improving the MMSE score (F = 12.31, p< .01) with a moderate effect size (partial eta square = .11) after controlling for group difference in age, gender, education, and having a diagnosis of dementia. CONCLUSION: The present study demonstrates the effectiveness of the expanded CST model on the improvement of cognitive ability of community-dwelling EwMD. More research is needed to further investigate this intervention model across cultures and societies.

RESUMO

AIM: The present research study aimed to identify and compare the clinical and non-clinical factors that predict the self-reported and proxy-reported health-related quality of life (HRQoL) of people with major neurocognitive disorder (PwND) who are living at home in a Chinese society. METHODS: A total of 57 Chinese PwND-family caregiver dyads that were using the services of local senior centers were recruited through a cross-sectional survey with convenience sampling. Each PwND and caregiver rated the PwND's HRQoL independently by using the Quality of Life-Alzheimer's disease measure. Additional measures included the Rosenberg Self-Esteem Scale (RSES), Index for Managing Memory Loss, Geriatric Depression Scale, Cornell Scale for Depression in Dementia and Zarit Burden Inventory. RESULTS: The results of hierarchical multiple linear regression analyses showed that the PwND's self-rated HRQoL and caregiver-rated HRQoL were found to be predicted by different clinical and non-clinical variables. In particular, the self-esteem of PwND had the highest predictive power for the self-rated HRQoL, whereas the caregiver burden is the only significant predictor for the caregiver-rated HRQoL. CONCLUSIONS: In the present study, the self-esteem of PwND and the caregiver's burden were found to be important factors predicting self-rated HRQoL and caregiver-rated HRQoL respectively, which is probably because of the influence of traditional Chinese cultural values. Thus, it is important for non-pharmacological interventions to address these special needs to promote HRQoL for this population. Geriatr Gerontol Int 2017; 17: 2319-2328.

RESUMO

BACKGROUND: As more patients achieve long-term survival, it has become important to understand mortality in liver transplantation (LT) recipients. METHODS: We conducted retrospective reviews of long-term outcome in two adult LT cohorts: 85 031 in the United Network for Organ Sharing (UNOS) database and 1458 transplanted at the University of Wisconsin (UW). RESULTS: During median follow-up of 3.2 years (UNOS) and 6.6 years (UW), 35.1% of UNOS patients and 44.2% of UW patients died; 43.1% of all UNOS deaths occurred in year 1 compared to 25.1% in the UW cohort. Deaths due to infection (other than viral hepatitis) or cardiovascular (CV) causes were most frequent in year 1 in both cohorts and then persisted at lower rates. In contrast, death from malignancy increased after year 1 to peak in years 1-5. Deaths due to rejection, hepatitis, or graft failure were infrequent. In the UW cohort, de novo malignancy was more common than recurrent tumor and correlated with smoking history. CONCLUSIONS: A coordinated holistic approach that focuses on limiting immunosuppression, infection, risky behaviors, and CV risks, while screening for cancer, is needed to extend the healthy lives of LT recipients.

RESUMO

BACKGROUND: Although self-stigma is found to have adverse effects on the lives of persons with mental illness, little is known on the self-stigma of these individuals in Chinese societies. OBJECTIVE: This research study explores the prevalence rate and predicting factors of self-stigma of consumers in two Chinese cities, Hong Kong and Guangzhou. METHODS: A cross-sectional research design is adopted which involves a random sample of 266 consumers from Hong Kong and a convenient sample of 208 consumers from Guangzhou. These individuals have been assessed in terms of their self-stigma, recovery, self-esteem and quality of life by using standardized assessment scales. RESULTS: In all, 38.3% of the Hong Kong participants and 49.5% of the Guangzhou participants report to have self-stigma. Also, self-stigma is found to be negatively related to self-esteem and quality of life. A logistic regression analysis shows that hope and well-being are predicting factors of self-stigma. CONCLUSION: Self-stigma is found to be higher in Guangzhou, probably due to the influence of traditional cultural values. Also, as hope and well-being are found to be predicting factors of self-stigma, suitable recovery-orientated interventions that facilitate hope and well-being should be developed so as to reduce self-stigma of consumers in Chinese societies.

RESUMO

Although liver is a key target for corticosteroid action, its role in immune function is largely unknown. We tested the hypothesis that stress levels of cortisol down regulate immune-relevant genes in rainbow trout (Oncorhynchus mykiss) liver. Hepatocytes were treated with lipopolysaccharide (LPS) for 24h either in the presence or absence of cortisol. LPS stimulated heat shock protein 70 expression, enhanced glycolytic capacity, and reduced glucose output. LPS stimulated mRNA abundance of cytokines and serum amyloid protein A (SAA), while suppressors of cytokine signaling (SOCS)-3 was reduced. Cortisol increased mRNA abundances of IL-1ß, SOCS-1 and SOCS-2, while inhibiting either basal or LPS-stimulated IL-8, TNF α2 and SAA. These cortisol-mediated effects were rescued by Mifepristone, a glucocorticoid receptor antagonist. Altogether, cortisol modulates the molecular immune response in trout hepatocytes. The upregulation of SOCS-1 and SOCS-2 by cortisol may be playing a key role in suppressing cytokine signaling and the associated inflammatory response.

RESUMO

Gankyrin is an oncoprotein containing seven ankyrin repeats that is overexpressed in hepatocellular carcinoma (HCC). Gankyrin binds to Mdm2, which results in accelerated ubiquitylation via degradation of p53, and it also plays an important role in cell proliferation. However, little is known about the relationships between p53 levels, cell proliferation, and gankyrin over-expression. In order to investigate the influence of gankyrin protein on p53 and Mdm2 in a zebrafish model, we injected human gankyrin (hgankyrin) containing expression vectors (pCS2-hgankyrin, pCS2-hgankyrin-EGFP) into zebrafish embryos. To measure p53 and Mdm2 expression in hgankyrin-injected embryos, RT-PCR, Northern blot and in-situ hybridization and BrdU immunostaining were used. In addition, to know the effect of hgankyrin on cell proliferation in vitro, cell viability assays such as MTT, trypan blue staining and RT-PCR following transfection of hgankyrin-containing vector into HEK 293 cell line were performed. In vivo results indicated that p53 mRNA levels decreased but those of Mdm2 were not decreased in the presence of hgankyrin. These results suggest that gankyrin downregulates p53 expression and not Mdm2 expression. In the study of cell proliferation, BrdU-positive cells were predominantly increased in the head and tail regions in hgankyrin-injected zebrafish. Additional in vitro studies using trypan blue staining and MTT assay showed that gankyrin-expressing HEK 293 cells proliferated at a faster rate, indicating that gankyrin promotes cell proliferation. Our results demonstrate that hgankyrin overexpression downregulates p53 expression and promotes cell proliferation in zebrafish. Gankyrin may play an important role in tumorigenesis via its effects on p53 and cell proliferation.
