Perceived psychosocial impacts of legalized same-sex marriage: A scoping review of sexual minority adults’ experiences
A growing body of literature provides important insights into the meaning and impact of the right to marry a same-sex partner among sexual minority people. We conducted a scoping review to 1) identify and describe the psychosocial impacts of equal marriage rights among sexual minority adults, and 2) explore sexual minority women (SMW) perceptions of equal marriage rights and whether psychosocial impacts differ by sex. Using Arksey and O’Malley’s framework we reviewed peer-reviewed English-language publications from 2000 through 2019. We searched six databases (PubMed, PsycINFO, CINAHL, Web of Science, JSTOR, and Sociological Abstracts) to identify English language, peer-reviewed journal articles reporting findings from empirical studies with an explicit focus on the experiences and perceived impact of equal marriage rights among sexual minority adults. We found 59 studies that met our inclusion criteria. Studies identified positive psychosocial impacts of same-sex marriage (e.g., increased social acceptance, reduced stigma) across individual, interpersonal (dyad, family), community (sexual minority), and broader societal levels. Studies also found that, despite equal marriage rights, sexual minority stigma persists across these levels. Only a few studies examined differences by sex, and findings were mixed. Research to date has several limitations; for example, it disproportionately represents samples from the U.S. and White populations, and rarely examines differences by sexual or gender identity or other demographic characteristics. There is a need for additional research on the impact of equal marriage rights and same-sex marriage on the health and well-being of diverse sexual minorities across the globe
Implementation of corticosteroids in treating COVID-19 in the ISARIC WHO Clinical Characterisation Protocol UK:prospective observational cohort study
BACKGROUND: Dexamethasone was the first intervention proven to reduce mortality in patients with COVID-19 being treated in hospital. We aimed to evaluate the adoption of corticosteroids in the treatment of COVID-19 in the UK after the RECOVERY trial publication on June 16, 2020, and to identify discrepancies in care. METHODS: We did an audit of clinical implementation of corticosteroids in a prospective, observational, cohort study in 237 UK acute care hospitals between March 16, 2020, and April 14, 2021, restricted to patients aged 18 years or older with proven or high likelihood of COVID-19, who received supplementary oxygen. The primary outcome was administration of dexamethasone, prednisolone, hydrocortisone, or methylprednisolone. This study is registered with ISRCTN, ISRCTN66726260. FINDINGS: Between June 17, 2020, and April 14, 2021, 47 795 (75·2%) of 63 525 of patients on supplementary oxygen received corticosteroids, higher among patients requiring critical care than in those who received ward care (11 185 [86·6%] of 12 909 vs 36 415 [72·4%] of 50 278). Patients 50 years or older were significantly less likely to receive corticosteroids than those younger than 50 years (adjusted odds ratio 0·79 [95% CI 0·70–0·89], p=0·0001, for 70–79 years; 0·52 [0·46–0·58], p80 years), independent of patient demographics and illness severity. 84 (54·2%) of 155 pregnant women received corticosteroids. Rates of corticosteroid administration increased from 27·5% in the week before June 16, 2020, to 75–80% in January, 2021. INTERPRETATION: Implementation of corticosteroids into clinical practice in the UK for patients with COVID-19 has been successful, but not universal. Patients older than 70 years, independent of illness severity, chronic neurological disease, and dementia, were less likely to receive corticosteroids than those who were younger, as were pregnant women. This could reflect appropriate clinical decision making, but the possibility of inequitable access to life-saving care should be considered.

Para-infectious brain injury in COVID-19 persists at follow-up despite attenuated cytokine and autoantibody responses
To understand neurological complications of COVID-19 better both acutely and for recovery, we measured markers of brain injury, inflammatory mediators, and autoantibodies in 203 hospitalised participants; 111 with acute sera (1–11 days post-admission) and 92 convalescent sera (56 with COVID-19-associated neurological diagnoses). Here we show that compared to 60 uninfected controls, tTau, GFAP, NfL, and UCH-L1 are increased with COVID-19 infection at acute timepoints and NfL and GFAP are significantly higher in participants with neurological complications. Inflammatory mediators (IL-6, IL-12p40, HGF, M-CSF, CCL2, and IL-1RA) are associated with both altered consciousness and markers of brain injury. Autoantibodies are more common in COVID-19 than controls and some (including against MYL7, UCH-L1, and GRIN3B) are more frequent with altered consciousness. Additionally, convalescent participants with neurological complications show elevated GFAP and NfL, unrelated to attenuated systemic inflammatory mediators and to autoantibody responses. Overall, neurological complications of COVID-19 are associated with evidence of neuroglial injury in both acute and late disease and these correlate with dysregulated innate and adaptive immune responses acutely
The P323L substitution in the SARS-CoV-2 polymerase (NSP12) confers a selective advantage during infection
Background
The mutational landscape of SARS-CoV-2 varies at the dominant viral genome sequence and minor genomic variant population. During the COVID-19 pandemic, an early substitution in the genome was the D614G change in the spike protein, associated with an increase in transmissibility. Genomes with D614G are accompanied by a P323L substitution in the viral polymerase (NSP12). However, P323L is not thought to be under strong selective pressure.
Results
Investigation of P323L/D614G substitutions in the population shows rapid emergence during the containment phase and early surge phase during the first wave. These substitutions emerge from minor genomic variants which become dominant viral genome sequence. This is investigated in vivo and in vitro using SARS-CoV-2 with P323 and D614 in the dominant genome sequence and L323 and G614 in the minor variant population. During infection, there is rapid selection of L323 into the dominant viral genome sequence but not G614. Reverse genetics is used to create two viruses (either P323 or L323) with the same genetic background. L323 shows greater abundance of viral RNA and proteins and a smaller plaque morphology than P323.
Conclusions
These data suggest that P323L is an important contribution in the emergence of variants with transmission advantages. Sequence analysis of viral populations suggests it may be possible to predict the emergence of a new variant based on tracking the frequency of minor variant genomes. The ability to predict an emerging variant of SARS-CoV-2 in the global landscape may aid in the evaluation of medical countermeasures and non-pharmaceutical interventions
Viral coinfections in hospitalized coronavirus disease 2019 patients recruited to the international severe acute respiratory and emerging infections consortium WHO clinical characterisation protocol UK study
Background
We conducted this study to assess the prevalence of viral coinfection in a well characterized cohort of hospitalized coronavirus disease 2019 (COVID-19) patients and to investigate the impact of coinfection on disease severity.
Methods
Multiplex real-time polymerase chain reaction testing for endemic respiratory viruses was performed on upper respiratory tract samples from 1002 patients with COVID-19, aged <1 year to 102 years old, recruited to the International Severe Acute Respiratory and Emerging Infections Consortium WHO Clinical Characterisation Protocol UK study. Comprehensive demographic, clinical, and outcome data were collected prospectively up to 28 days post discharge.
Results
A coinfecting virus was detected in 20 (2.0%) participants. Multivariable analysis revealed no significant risk factors for coinfection, although this may be due to rarity of coinfection. Likewise, ordinal logistic regression analysis did not demonstrate a significant association between coinfection and increased disease severity.
Conclusions
Viral coinfection was rare among hospitalized COVID-19 patients in the United Kingdom during the first 18 months of the pandemic. With unbiased prospective sampling, we found no evidence of an association between viral coinfection and disease severity. Public health interventions disrupted normal seasonal transmission of respiratory viruses; relaxation of these measures mean it will be important to monitor the prevalence and impact of respiratory viral coinfections going forward
Delayed mucosal anti-viral responses despite robust peripheral inflammation in fatal COVID-19
Background
While inflammatory and immune responses to SARS-CoV-2 infection in peripheral blood are extensively described, responses at the upper respiratory mucosal site of initial infection are relatively poorly defined. We sought to identify mucosal cytokine/chemokine signatures that distinguished COVID-19 severity categories, and relate these to disease progression and peripheral inflammation.
Methods
We measured 35 cytokines and chemokines in nasal samples from 274 patients hospitalised with COVID-19. Analysis considered the timing of sampling during disease, as either the early (0-5 days post-symptom onset) or late (6-20 days post-symptom onset).
Results
Patients that survived severe COVID-19 showed IFN-dominated mucosal immune responses (IFN-γ, CXCL10 and CXCL13) early in infection. These early mucosal responses were absent in patients that would progress to fatal disease despite equivalent SARS-CoV-2 viral load. Mucosal inflammation in later disease was dominated by IL-2, IL-10, IFN-γ, and IL-12p70, which scaled with severity but did not differentiate patients who would survive or succumb to disease. Cytokines and chemokines in the mucosa showed distinctions from responses evident in the peripheral blood, particularly during fatal disease.
Conclusions
Defective early mucosal anti-viral responses anticipate fatal COVID-19 but are not associated with viral load. Early mucosal immune responses may define the trajectory of severe COVID-19
A prenylated dsRNA sensor protects against severe COVID-19
Inherited genetic factors can influence the severity of COVID-19, but the molecular explanation underpinning a genetic association is often unclear. Intracellular antiviral defenses can inhibit the replication of viruses and reduce disease severity. To better understand the antiviral defenses relevant to COVID-19, we used interferon-stimulated gene (ISG) expression screening to reveal that OAS1, through RNase L, potently inhibits SARS-CoV-2. We show that a common splice-acceptor SNP (Rs10774671) governs whether people express prenylated OAS1 isoforms that are membrane-associated and sense specific regions of SARS-CoV-2 RNAs, or only express cytosolic, nonprenylated OAS1 that does not efficiently detect SARS-CoV-2. Importantly, in hospitalized patients, expression of prenylated OAS1 was associated with protection from severe COVID-19, suggesting this antiviral defense is a major component of a protective antiviral response

LGBTQ+ Resilience in Community: Towards Strategies for Preventing and Managing Sexual Minority Women’s Mental and Behavioral Health Concerns Together
Background: Research on the wellbeing and resilience of LGBTQ+ people including sexual minority women (SMW; whose who identify as women and have a sexual orientation other than heterosexual) is currently of paramount importance given recent challenges spurred by the global COVID-19 pandemic, increased social and political polarization around race, gender, and sexuality, and rising anti-LGBTQ+ rhetoric and policies in the USA. Even prior to these contemporary stressors, SMW have experienced about twice the rates of depression, anxiety, and alcohol use disorder compared to heterosexual women, and there is concern that the pandemic may have exacerbated these disparities. Given SMW’s elevated pre-pandemic health concerns, there is a need to clearly characterize how SMW enact resilience, receive the support needed to stay well, and maintain wellbeing in this rapidly changing, stressful world. Methods: The present study examines these topics though a series of three inter-related research manuscripts that build on each other. First is a quantitative analysis of the protective nature of resilience against depression, anxiety, and alcohol use disorder in a racially diverse sample of SMW (N=520) reported in a quantitative public health-style analysis. The second examines the relationship between resilience and a key factor underlying it – social support –using intersectional quantitative methods to determine the most protective types of social support and to elucidate potential within-SMW differences by race, sexual orientation, and their intersections. Lastly, these research foci were applied to the current social context using qualitative phenomenological methodology to characterize shifts in social support, and mental and behavioral health for a sub-set of SMW (n=17) at the onset of the COVID-19 pandemic. Results: Higher levels of resilience were associated with lower adjusted odds of depression, anxiety, and alcohol use disorder. SMW who were older and those with higher household income reported the highest levels of resilience. When considering the role of social support in resilience, higher levels of social support were associated with higher levels of resilience, which was consistent across SMW of all demographics. Few within-group differences in this relationship were found by race, sexual orientation, and their intersections. Social support from family, friends, significant others, and especially the LGBTQ+ community were each predictive of greater resilience. Participant interviews shed further light on how changes in social support occurred in at the pandemic’s onset and were at times related to changes in mental and behavioral health.Implications: This work has implications for social work practice, intervention research, and policy advocacy. Since resilience and social support appear protective against the most common mental and behavioral health concerns in SMW, multi-level interventions that increase access to social support and strengthen resources for resilience are needed, as they have the potential to ameliorate persistent health disparities. This could include individual, couple, family, or group therapy; peer support; and case management tailored to SMW’s specific life experiences and needs. Interventions drawing on social ecological and strengths-based approaches that consider how individual-level outcomes are impacted by broader societal factors like sexism, heterosexism, and racism are needed. Policy advocacy is also needed to ensure that LGBTQ+ community spaces and organizations, which facilitate access to protective LGBTQ+ support, can remain open and financially viable ongoing

Overcoming Technological Challenges: Lessons Learned from a Telehealth Counseling Study.
Background: Telehealth methods, including video chat counseling, have been growing in popularity within the behavioral health counseling field for over a decade. While video-based counseling methods have been shown to be effective and convenient, they have unique challenges stemming from the technology they use. Technical challenges can negatively impact appointment flow, intervention effectiveness, and the satisfaction of both patients and clinicians. Methodology: The Y2TEC (Youth to Text or Telehealth for Engagement in HIV Care) study is a pilot randomized control trial examining the feasibility and acceptability of a video counseling series provided to young adults (ages 18-29) living with HIV. The study's clinicians provided about 500 video-based counseling sessions through the Zoom videoconferencing platform. The study team then developed recommendations for overcoming technical challenges through a review of the best practice literature, insights from the clinicians and study coordinator, engaging in consultations during supervision meetings, receiving verbal feedback from participants, and reviewing logs of technical challenges. Results: Through our experience, we have found that quality of video-based counseling services can be greatly improved with minor intentional technological modifications in preparation and provision of services. We provide an overview of common challenges and corresponding recommendations to address them. Conclusion: This article can help clinicians improve their quality of telehealth sessions by identifying several common technological challenges that can occur during video chat sessions, exploring the impact of these challenges on session dynamics and providing concise, best practice-based recommendations to mitigate these issues that clinicians face
