ABSTRACT

This study examined whether self-stigma content and process would prospectively influence parental warmth and hostility through increasing parenting stress among parents of children with autism spectrum disorder (ASD). On three occasions across two years, 441 Hong Kong parents of children with ASD provided questionnaire data. Path analyses showed that self-stigma content and process were associated with greater parenting stress, which was, in turn, associated with reduced parental warmth and increased parental hostility. Our findings reveal the longitudinal influences of self-stigma on parenting practices and demonstrate how these influences can be explained by parenting stress. Our findings also suggest the importance of supporting parents of children with ASD to mitigate self-stigma and associated parenting stress in improving their parenting practices.

ABSTRACT

PURPOSE: The present study aimed to investigate how the interpersonal (experienced discrimination) and intrapersonal (anticipated stigma and internalized stigma) manifestations of psychiatric stigma may affect engaged living and life satisfaction among people with mental illness. In this study, we developed and evaluated a conceptual model to clarify how experienced discrimination may lead to anticipated stigma and internalized stigma and thereby impede engaged living and reduce life satisfaction. METHODS: A total of 205 Hong Kong Chinese people with mental illness completed standardized questionnaire measures of experienced discrimination, anticipated stigma, internalized stigma, engaged living, and life satisfaction. The associations among these variables were analyzed using path analyses and bootstrap analyses. RESULTS: Path analyses showed that experienced discrimination was related to higher levels of anticipated stigma and internalized stigma, which were, in turn, linked to lesser engaged living and consequently lower life satisfaction. Bootstrap analyses further revealed that experienced discrimination had significant indirect effects on life satisfaction via anticipated stigma and engaged living and via internalized stigma and engaged living. CONCLUSIONS: Theoretically, our study uncovers how the interpersonal and intrapersonal manifestations of psychiatric stigma may adversely affect engaged living and life satisfaction among people with mental illness. Practically, our study points to the importance of developing and implementing stigma-related interventions at societal and individual levels in order to enable people with mental illness to live fulfilling and satisfying lives.

ABSTRACT

BACKGROUND: Although the public and courtesy stigma of autism spectrum disorder (ASD) are prevalent, there are very few studies examining their adverse psychological effects on parents of children with ASD or exploring plausible factors that can alleviate these adverse effects. The present study addressed these literature gaps by investigating the longitudinal linkages of public and courtesy stigma to detrimental cognitive (i.e., self-stigma content and process) and affective (i.e., perceived stress and symptoms of depression and anxiety) consequences for parents of children with ASD and testing if these linkages would be moderated by trait mindfulness. METHODS: At two time points separated by 12 months, 372 Hong Kong parents of children with ASD provided questionnaire data on public and courtesy stigma, mindfulness, self-stigma content and process, perceived stress, and symptoms of depression and anxiety. RESULTS: Hierarchical regressions showed that public and courtesy stigma interacted significantly with mindfulness at baseline in predicting self-stigma content and process, perceived stress, and symptoms of depression and anxiety at follow-up. Moreover, simple slope analyses showed that the linkages of public and courtesy stigma to the five detrimental psychological consequences were weaker in parents with high mindfulness than in those with low mindfulness. CONCLUSIONS: Our findings highlight the longitudinal linkages of public and courtesy stigma to detrimental cognitive and affective consequences for parents of children with ASD, and reveal the plausible protective effects of mindfulness against such linkages. These findings suggest the potential utility of increasing mindfulness in parents of children with ASD in coping with community stigma and improving mental health.

ABSTRACT

The impact of vaccination on SARS-CoV-2 infectiousness is not well understood. We compared longitudinal viral shedding dynamics in unvaccinated and fully vaccinated adults. SARS-CoV-2-infected adults were enrolled within 5 days of symptom onset and nasal specimens were self-collected daily for two weeks and intermittently for an additional two weeks. SARS-CoV-2 RNA load and infectious virus were analyzed relative to symptom onset stratified by vaccination status. We tested 1080 nasal specimens from 52 unvaccinated adults enrolled in the pre-Delta period and 32 fully vaccinated adults with predominantly Delta infections. While we observed no differences by vaccination status in maximum RNA levels, maximum infectious titers and the median duration of viral RNA shedding, the rate of decay from the maximum RNA load was faster among vaccinated; maximum infectious titers and maximum RNA levels were highly correlated. Furthermore, amongst participants with infectious virus, median duration of infectious virus detection was reduced from 7.5 days (IQR: 6.0-9.0) in unvaccinated participants to 6 days (IQR: 5.0-8.0) in those vaccinated (P=0.02). Accordingly, the odds of shedding infectious virus from days 6 to 12 post-onset were lower among vaccinated participants than unvaccinated participants (OR 0.42 95% CI 0.19-0.89). These results indicate that vaccination had reduced the probability of shedding infectious virus after 5 days from symptom onset. Significance statementWe present longitudinal data on the magnitude, duration and decay rate of viral RNA and the magnitude and duration of infectious virus in nasal specimens from vaccinated and unvaccinated participants. On average, vaccinated participants (infected with the highly transmissible Delta variant) showed a lower probability of having infectious virus after 5 days of symptoms compared to unvaccinated participants (infected with mostly pre-delta viral lineages), even though both groups had a similar magnitude of infectious virus at or near the peak. These data help improve our understanding of the duration of the infectious period when infection occurs following vaccination and serves as a reference for future studies of shedding dynamics following infections with novel variants of concern.

ABSTRACT

Sexual identity stress may damage the well-being of lesbian, gay, and bisexual (LGB) individuals, but limited research has examined the potential protective factors in this context. The present study addressed this research gap by testing a psychological flexibility model of sexual identity development and positive mental health among LGB individuals. We hypothesized that psychological flexibility would be associated with greater engaged living (i.e., valued living and life fulfillment), which would, in turn, be linked to lower sexual identity stress (i.e., identity uncertainty, acceptance concern, internalized homonegativity, sexuality concealment, and difficult process of identity development) and then better well-being (i.e., emotional, psychological, and social well-being). A total of 401 LGB individuals completed questionnaire measures of psychological flexibility, engaged living, sexual identity stress, and well-being. Structural equation modeling showed that psychological flexibility was related to greater engaged living, which was, in turn, related to lower sexual identity stress and then better well-being. Bootstrap analyses further revealed that psychological flexibility had significant indirect effects on sexual identity stress via engaged living and on well-being via engaged living and sexual identity stress. In addition, multigroup analyses demonstrated that the mediation model held across women and men and across lesbian/gay and bisexual individuals. Theoretically, this study elucidated how psychological flexibility could enable LGB individuals to reduce sexual identity stress and improve well-being through living a valuable and fulfilling life. Practically, this study pointed to the utility of psychological flexibility training in facilitating LGB individuals to develop a positive sexual identity and enhance positive mental health.

ABSTRACT

The COVID-19 pandemic is exacting an increasing toll worldwide, with new SARS-CoV-2 variants emerging that exhibit higher infectivity rates and that may partially evade vaccine and antibody immunity1. Rapid deployment of non-invasive therapeutic avenues capable of preventing infection by all SARS-CoV-2 variants could complement current vaccination efforts and help turn the tide on the COVID-19 pandemic2. Here, we describe a novel therapeutic strategy targeting the SARS-CoV-2 RNA using locked nucleic acid antisense oligonucleotides (LNA ASOs). We identified an LNA ASO binding to the 5 leader sequence of SARS-CoV-2 ORF1a/b that disrupts a highly conserved stem-loop structure with nanomolar efficacy in preventing viral replication in human cells. Daily intranasal administration of this LNA ASO in the K18-hACE2 humanized COVID-19 mouse model potently (98-99%) suppressed viral replication in the lungs of infected mice, revealing strong prophylactic and treatment effects. We found that the LNA ASO also represses viral infection in golden Syrian hamsters, and is highly efficacious in countering all SARS-CoV-2 "variants of concern" tested in vitro and in vivo, including B.1.427, B.1.1.7, and B.1.351 variants3. Hence, inhaled LNA ASOs targeting SARS-CoV-2 represents a promising therapeutic approach to reduce transmission of variants partially resistant to vaccines and monoclonal antibodies, and could be deployed intranasally for prophylaxis or via lung delivery by nebulizer to decrease severity of COVID-19 in infected individuals. LNA ASOs are chemically stable and can be flexibly modified to target different viral RNA sequences4, and they may have particular impact in areas where vaccine distribution is a challenge, and could be stockpiled for future coronavirus pandemics.

ABSTRACT

Research shows that sense of community may enable lesbian, gay, and bisexual (LGB) individuals to resist and fight against societal heterosexism and increase their positive sense of self. Less is known, however, about the underlying processes. The present study examined whether sense of community would affect sense of self (i.e., identity affirmation and self-esteem) through critical consciousness (i.e., critical reflection and critical action) among LGB individuals. A total of 401 LGB individuals from Hong Kong, China, provided cross-sectional questionnaire data on sense of community, critical reflection, critical action, identity affirmation, and self-esteem. Structural equation modeling and bootstrap analyses were performed to analyze the direct and indirect relations among the variables. Results showed that sense of community was positively associated with critical action, and this association was mediated by critical reflection. Moreover, critical action was positively associated with self-esteem, and this association was mediated by identity affirmation. Theoretically, this study demonstrated how LGB individuals' sense of community may have a positive impact on their sense of self through the mechanism of critical consciousness. Practically, this study pointed to the utility of cultivating positive in-group perceptions among LGB individuals in liberating them from oppressive ideology, mobilizing them to resist social injustice, enhancing their identity affirmation, and increasing their self-esteem.

ABSTRACT

As of January of 2021, the highly transmissible B.1.1.7 variant of SARS-CoV-2, which was first identified in the United Kingdom (U.K.), has gained a strong foothold across the world. Because of the sudden and rapid rise of B.1.1.7, we investigated the prevalence and growth dynamics of this variant in the United States (U.S.), tracking it back to its early emergence and onward local transmission. We found that the RT-qPCR testing anomaly of S gene target failure (SGTF), first observed in the U.K., was a reliable proxy for B.1.1.7 detection. We sequenced 212 B.1.1.7 SARS-CoV-2 genomes collected from testing facilities in the U.S. from December 2020 to January 2021. We found that while the fraction of B.1.1.7 among SGTF samples varied by state, detection of the variant increased at a logistic rate similar to those observed elsewhere, with a doubling rate of a little over a week and an increased transmission rate of 35-45%. By performing time-aware Bayesian phylodynamic analyses, we revealed several independent introductions of B.1.1.7 into the U.S. as early as late November 2020, with onward community transmission enabling the variant to spread to at least 30 states as of January 2021. Our study shows that the U.S. is on a similar trajectory as other countries where B.1.1.7 rapidly became the dominant SARS-CoV-2 variant, requiring immediate and decisive action to minimize COVID-19 morbidity and mortality.

ABSTRACT

Following its emergence in Wuhan, China, in late November or early December 2019, the SARS-CoV-2 virus has rapidly spread throughout the world. Genome sequencing of SARS-CoV-2 strains allows for the reconstruction of transmission history connecting these infections. Here, we analyze 346 SARS-CoV-2 genomes from samples collected between 20 February and 15 March 2020 from infected patients in Washington State, USA. We found that the large majority of SARS-CoV-2 infections sampled during this time frame appeared to have derived from a single introduction event into the state in late January or early February 2020 and subsequent local spread, indicating cryptic spread of COVID-19 before active community surveillance was implemented. We estimate a common ancestor of this outbreak clade as occurring between 18 January and 9 February 2020. From genomic data, we estimate an exponential doubling between 2.4 and 5.1 days. These results highlight the need for large-scale community surveillance for SARS-CoV-2 and the power of pathogen genomics to inform epidemiological understanding.
