ABSTRACT

PURPOSE: The physician voice is crucial to shaping health policy and public health guidelines, particularly during COVID-19. However, there are gaps in health policy and advocacy education within graduate medical education. This study sought to characterise the impact of a virtual COVID-19 focused advocacy day among medical trainees in Massachusetts. STUDY DESIGN: The half-day event featured speakers drawn from government relations experts, physician advocates, and state and federal legislators as well as breakout discussions among attendees. A 25-question Redcap survey and list of resources/opportunities for continued advocacy was administered to all participants at event's conclusion on 19 May 2020. RESULTS: There were 60 responses from 141 participants (43% response rate). One-third reported no prior formal health policy instruction, and over half reported getting information from news publications, social media and peers. 58% believed physician involvement in advocacy to be 'extremely important' prior to COVID-19; 83% believed the same after onset of COVID-19 (p<0.0001). The most common barriers to advocacy engagement were lack of time and knowledge. Most attendees felt participation increased their knowledge and likelihood to engage in the COVID-19 response, imparted useful skills/knowledge for continued advocacy, increased their interest in future similar events, and that such events should be available to all trainees. CONCLUSIONS: Trainees recognise the importance of health policy and advocacy and value opportunities to gain the necessary skills/knowledge to effect tangible change. Virtual advocacy days can be replicated nationwide to help trainees learn about advocacy efforts and find their legislative voices during COVID-19 and beyond.

ABSTRACT

SARS-CoV-2 vaccine immunogenicity varies between individuals, and immune responses correlate with vaccine efficacy. Using data from 1,076 participants enrolled in ChAdOx1 nCov-19 vaccine efficacy trials in the United Kingdom, we find that inter-individual variation in normalised antibody responses against SARS-CoV-2 spike (S) and its receptor binding domain (RBD) at 28 days following first vaccination shows genome-wide significant association with major histocompatibility complex (MHC) class II alleles. The most statistically significant association with higher levels of anti-RBD antibody was HLA-DQB1*06 (P = 3.2 × 10-9), which we replicate in 1,677 additional vaccinees. Individuals carrying HLA-DQB1*06 alleles were less likely to experience PCR-confirmed breakthrough infection during the ancestral SARS-CoV-2 virus and subsequent Alpha-variant waves compared with non-carriers (HR 0.63, 0.42-0.93, P = 0.02). We identify a distinct S-derived peptide that is predicted to bind differentially to HLA-DQB1*06 compared with other similar alleles, and find evidence of increased spike-specific memory B-cell responses in HLA-DQB1*06 carriers at 84 days following first vaccination. Our results demonstrate association of HLA type with COVID-19 vaccine antibody response and risk of breakthrough infection, with implications for future vaccine design and implementation.

ABSTRACT

BACKGROUND: Direct evaluation of vascular inflammation in patients with COVID-19 would facilitate more efficient trials of new treatments and identify patients at risk of long-term complications who might respond to treatment. We aimed to develop a novel artificial intelligence (AI)-assisted image analysis platform that quantifies cytokine-driven vascular inflammation from routine CT angiograms, and sought to validate its prognostic value in COVID-19. METHODS: For this prospective outcomes validation study, we developed a radiotranscriptomic platform that uses RNA sequencing data from human internal mammary artery biopsies to develop novel radiomic signatures of vascular inflammation from CT angiography images. We then used this platform to train a radiotranscriptomic signature (C19-RS), derived from the perivascular space around the aorta and the internal mammary artery, to best describe cytokine-driven vascular inflammation. The prognostic value of C19-RS was validated externally in 435 patients (331 from study arm 3 and 104 from study arm 4) admitted to hospital with or without COVID-19, undergoing clinically indicated pulmonary CT angiography, in three UK National Health Service (NHS) trusts (Oxford, Leicester, and Bath). We evaluated the diagnostic and prognostic value of C19-RS for death in hospital due to COVID-19, did sensitivity analyses based on dexamethasone treatment, and investigated the correlation of C19-RS with systemic transcriptomic changes. FINDINGS: Patients with COVID-19 had higher C19-RS than those without (adjusted odds ratio [OR] 2·97 [95% CI 1·43-6·27], p=0·0038), and those infected with the B.1.1.7 (alpha) SARS-CoV-2 variant had higher C19-RS values than those infected with the wild-type SARS-CoV-2 variant (adjusted OR 1·89 [95% CI 1·17-3·20] per SD, p=0·012). C19-RS had prognostic value for in-hospital mortality in COVID-19 in two testing cohorts (high [≥6·99] vs low [<6·99] C19-RS; hazard ratio [HR] 3·31 [95% CI 1·49-7·33], p=0·0033; and 2·58 [1·10-6·05], p=0·028), adjusted for clinical factors, biochemical biomarkers of inflammation and myocardial injury, and technical parameters. The adjusted HR for in-hospital mortality was 8·24 (95% CI 2·16-31·36, p=0·0019) in patients who received no dexamethasone treatment, but 2·27 (0·69-7·55, p=0·18) in those who received dexamethasone after the scan, suggesting that vascular inflammation might have been a therapeutic target of dexamethasone in COVID-19. Finally, C19-RS was strongly associated (r=0·61, p=0·00031) with a whole blood transcriptional module representing dysregulation of coagulation and platelet aggregation pathways. INTERPRETATION: Radiotranscriptomic analysis of CT angiography scans introduces a potentially powerful new platform for the development of non-invasive imaging biomarkers. Application of this platform in routine CT pulmonary angiography scans done in patients with COVID-19 produced the radiotranscriptomic signature C19-RS, a marker of cytokine-driven inflammation driving systemic activation of coagulation and responsible for adverse clinical outcomes, which predicts in-hospital mortality and might allow targeted therapy.

ABSTRACT

PURPOSE: Mobile health (mHealth) technology has increased dramatically in the wake of the pandemic. Less research has focused on people with mobility impairing (PMI) disabilities. This study determined the prevalence of mHealth use among PMI adults during the COVID-19 escalation and examines demographic, health and COVID-19 concerns correlates. METHODS: PMI adults (N = 304) completed an online survey investigating mHealth use and COVID-19 concerns related to food access in June of 2020. Smartphone and mHealth use were measured with an adapted version of the survey used in the Pew Internet & American Life project. Descriptive and multivariable analyses were conducted to determine associations of demographics, health status, and COVID-19 concerns with mHealth use. About two-thirds (N = 201) of the sample were mHealth users (owned a smartphone and engaged in health-promoting behaviors with the smartphone; e.g., sought online information, tracked health behaviors, used patient portals). RESULTS: Having hypertension was associated with higher mHealth use, and having higher COVID-19 concerns about food access was associated with higher mHealth use. Those who used mHealth were also more engaged with smartphone apps for communication, services, and entertainment. Only the association between educational attainment and mHealth use remained significant after adjusting for other covariates in multivariable logistic regression models. DISCUSSION: PMIs continue to need support in the use of mHealth technology to help maximize access to potentially important tools for rehabilitation and health management. There is a need to continue to investigate mHealth and its applications for people with disabilities.Implications for RehabilitationMany people with mobility impairing disabilities may be missing opportunities for mHealth rehabilitation and healthcare.COVID-19 has widened existing gaps in access and use of mHealth technology among people with mobility impairing disabilities.Focused education is needed to help people with disabilities exploit the full range of services of their smartphones to increase access to care, social connectivity, and other important goods and services to enhance rehabilitation and health management.

ABSTRACT

INTRODUCTION: Vaccines have had a transformative impact on child health. Despite this impact, the immunological processes involved in protective responses are not entirely understood and vaccine development has been largely empirical. Recent technological advances offer the opportunity to reveal the immunology underlying vaccine response at an unprecedented resolution. These data could revolutionize the way vaccines are developed and tested and further augment their role in securing the health of children around the world. AREAS COVERED: Systems level information and tools are now being deployed by vaccinologists at all stages of the vaccine development pathway; however, this review will specifically describe some of the key findings that have be gleaned from multi-omics datasets collected in the context of childhood immunization. EXPERT OPINION: Despite the success of vaccines, there remains hard-to-target pathogens, refractory to current vaccination strategies. Moreover, zoonotic diseases with pandemic potential are a threat to global health, as recently illustrated by COVID-19. Systems vaccinology holds a great deal of promise in revealing a greater understanding of vaccine responses and consequently modernizing vaccinology. However, there is a need for future studies - particularly in vulnerable populations that are targets for vaccination programmes - if this potential is to be fulfilled.

ABSTRACT

Over the past two years, the SARS-CoV-2 pandemic has highlighted the impact that emerging pathogens can have on global health. The development of new and effective vaccine technologies is vital in the fight against such threats. Viral vectors are a relatively new vaccine platform that relies on recombinant viruses to deliver selected immunogens into the host. In response to the SARS-CoV-2 pandemic, the development and subsequent rollout of adenoviral vector vaccines has shown the utility, impact, scalability and efficacy of this platform. Shown to elicit strong cellular and humoral immune responses in diverse populations, these vaccine vectors will be an important approach against infectious diseases in the future.

ABSTRACT

Background Antibody levels against SARS-CoV-2 can be used as an indicator of recent or past vaccination or infection. However, the prognostic value of antibodies targeting the receptor binding protein (anti-RBD) in hospitalized patients is not widely reported. Purpose Determine prognostic impact of SARS-CoV-2 antibody quantification at the time of admission on clinical outcomes in hospitalized COVID-19 patients. Methods We conducted a pilot observational study on patients hospitalized with SARS-CoV-2 infection to determine the prognostic impact of antibody quantitation within the first two days of admission. Anti-nucleocapsid IgG (anti-N) and Anti-RBD levels were measured. Anti-RBD level of 500 AU/mL was used as a cutoff to stratify patients. Spearman’s rank Coefficient (rs) was used to demonstrate association. Results Of the 26 patients included, those who were vaccinated more frequently tested positive for Anti-RBD (100% vs 46.2%, P = 0.005) with higher median titer level (623 vs 0, P = 0.011) compared to unvaccinated patients. Anti-N positivity was more frequently seen in unvaccinated patients (53.9% vs 7.7%, P = 0.03). Anti-RBD levels >500 were associated with lower overall hospital length of stay (LOS)(5 vs 10 days, P = 0.046). The analysis employing a Spearman Rank coefficient demonstrated a strong negative correlation between anti-S titer and LOS (rs=−.515, p = 0.007) and a moderate negative correlation with oxygen needs (rs =−.401, p = 0.042). Conclusion Anti-RBD IgG levels were associated with lower LOS and oxygen needs during hospitalization. Further studies are needed to determine if levels on admission can be used as a prognostic indicator.

ABSTRACT

The trajectories of acquired immunity to severe acute respiratory syndrome coronavirus 2 infection are not fully understood. We present a detailed longitudinal cohort study of UK healthcare workers prior to vaccination, presenting April-June 2020 with asymptomatic or symptomatic infection. Here we show a highly variable range of responses, some of which (T cell interferon-gamma ELISpot, N-specific antibody) wane over time, while others (spike-specific antibody, B cell memory ELISpot) are stable. We use integrative analysis and a machine-learning approach (SIMON - Sequential Iterative Modeling OverNight) to explore this heterogeneity. We identify a subgroup of participants with higher antibody responses and interferon-gamma ELISpot T cell responses, and a robust trajectory for longer term immunity associates with higher levels of neutralising antibodies against the infecting (Victoria) strain and also against variants B.1.1.7 (alpha) and B.1.351 (beta). These variable trajectories following early priming may define subsequent protection from severe disease from novel variants.

ABSTRACT

INTRODUCTION: Individuals experiencing homelessness have elevated smoking rates in addition to chronic and acute physical and mental health conditions, which may increase chances for complications associated with COVID-19 recovery. Unfortunately, there is underuse of tobacco cessation services in many agencies (e.g., substance use treatment centers, mental health treatment centers) providing care to these individuals. The purpose of the current study was to evaluate the feasibility of providing tobacco cessation treatment alongside local COVID-19 emergency response efforts. METHOD: Taking Texas Tobacco Free (TTTF) partnered with relevant emergency response teams at 5 isolation centers (repurposed hotels) in Austin, Texas, to address tobacco use among presumed or confirmed COVID-19 positive individuals who had nowhere else to seek care and shelter. TTTF trained staff on tobacco cessation treatment; specifically, the 5A's and use of nicotine replacement therapy. RESULTS: Over 5 months in 2020; 170 of 379 (44.9%) isolation center residents were reached and assessed for cigarette or vape use. Smoking/vaping prevalence was 70.6%, and 41.7% of tobacco users accepted cessation treatment. DISCUSSION: Results suggest the feasibility and potential acceptability of providing tobacco treatment services in similar care settings during local emergency response efforts, including but potentially not limited to the COVID-19 pandemic. Further, this initiates a call to action for health care providers to deliver tobacco use cessation services for typically hard-to-reach groups (e.g., individuals/families experiencing homelessness) who may have increased contact with service agencies and health providers during times of crisis. Limitations and suggestions for future implementation are also provided. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

ABSTRACT

Tobacco use is disproportionately elevated among patients with substance use disorders relative to the general U.S. population. Tobacco interventions are lacking within substance use treatment centers (SUTCs) due to lack of knowledge and training. This study examined knowledge gain and the organizational factors that might moderate knowledge gains following tobacco education training provided to employees (N = 580) within 15 SUTCs that were participating in a tobacco-free workplace program. The number of total annual patient visits, unique annual patient visits, number of full-time employees, and organizational readiness for implementing change (ORIC) as assessed prior to implementation were examined as potential moderators. Results demonstrated significant knowledge gain (p < 0.001) after training overall; individually, 13 SUTCs had significant knowledge gain (p's < 0.014). SUTCs with fewer total annual patient visits and fewer full-time employees showed greater knowledge gains. The ORIC total score and all but one of its subscales (Resource Availability) moderated knowledge gain. SUTCs with greater initial Change Efficacy (p = 0.029), Valence (p = 0.027), and Commitment (p < 0.001) had greater knowledge gain than SUTCs with lower scores on these constructs; SUTCs with greater Task Knowledge (p < 0.001) regarding requirements for change exhibited less knowledge gain. Understanding the organizational-level factors impacting training effectiveness can inform efforts in organizational change and tobacco control program implementation.

ABSTRACT

Objectives: Residents in nursing homes are being isolated to prevent exposure to COVID-19. Many are prone to depression, anxiety and loneliness, and extra isolation leaves them vulnerable to compromised mental health. In this study, trained volunteers providing befriending for residents with symptoms of depression, anxiety and loneliness switched to remote befriending during COVID-19. The purpose of this study was to gauge volunteer perceptions of the switch.Methods: A qualitative phenomenological approach was used to understand how switching to remote befriending impacted on volunteers and residents. A convenience sample of 18 participants responded to questions either in individual or group interviews.Results: Volunteers adapted their befriending visits, switching from face to face visits to remote options. The format was decided collaboratively. Hearing impairments hindered phone calls. Residents sometimes felt uncomfortable with digital technology but on the whole, the change to remote "visiting" was accepted.Conclusions: Further research is being conducted to gauge mental health outcomes for residents. Most volunteers and residents accepted the switch to remote befriending as better than no contact.Clinical implications: Volunteers can provide valuable support for residents living with social isolation during COVID-19. The format for social support needs to be decided collaboratively between volunteer and resident.

ABSTRACT

Critical care cardiology has been impacted by the coronavirus disease-2019 (COVID-19) pandemic. COVID-19 causes severe acute respiratory distress syndrome, acute kidney injury, as well as several cardiovascular complications including myocarditis, venous thromboembolic disease, cardiogenic shock, and cardiac arrest. The cardiac intensive care unit is rapidly evolving as the need for critical care beds increases. Herein, we describe the changes to the cardiac intensive care unit and the evolving role of critical care cardiologists and other clinicians in the care of these complex patients affected by the COVID-19 pandemic. These include practical recommendations regarding structural and organizational changes to facilitate care of patients with COVID-19; staffing and personnel changes; and health and safety of personnel. We draw upon our own experiences at NewYork-Presbyterian Columbia University Irving Medical Center to offer insights into the unique challenges facing critical care clinicians and provide recommendations of how to address these challenges during this unprecedented time.
