Temporal Trends of Early COVID-19 Infections in New York City Transit Workers and Residents: March 01, 2020-May 02, 2020.

The continuity of public transportation was necessary during the COVID-19 pandemic so that essential workers could report for duty. Therefore, it is important to consider COVID-19's impact on transit workers themselves. We described COVID-19 incidence rates over time in New York City (NYC) transit workers and the NYC general population during March-May, 2020. NYC transit COVID-19 cases were abstracted from occupational injury and illness logs, and health department data was used to ascertain NYC resident cases. COVID-19 rates among transit workers peaked during the week of March 22-28 (429.8 cases/100,000 workers). The peak in transit workers occurred 1-2weeks before the general public's peak (March 29-April 4: 368.8 cases/100,000 people; April 5-11: 357.8 cases/100,000 people). These data suggest that NYC transit workers may have been impacted by COVID-19 earlier than the general public. Thus, improving early detection and response of respiratory disease outbreaks may be vital to protecting transit workers.

Bacteriuria and antibiotic use during the third wave of COVID-19 intensive care in Sweden

Background Urinary tract infections (UTIs) are prevalent among patients carrying indwelling catheters in the intensive care unit (ICU). This study investigates antibiotic use and bacterial colonisation among ICU patients during the third wave of the COVID-19 pandemic, building on our prior discovery of increased Enterococcus colonisation associated with increased cephalosporin use in early COVID-19. Methods Longitudinal urine samples from COVID-19 patients (n = 109) with transurethral catheterisation were analysed for bacterial prevalence, further identified via MALDI-TOF. Microbiological results were combined with clinical data obtained daily, assessed and compared with COVID-19 waves 1 and 2. Results Patients in wave 3 exhibited improved outcomes compared to those in waves 1 and 2, alongside a decrease in antibiotic use. Staphylococcus emerged as the primary bacterium and early colonizer of the urinary tract, potentially due to the absence of antibiotic treatment. Our results imply that length of stay (LOS) correlates solely with enteric pathogens and that antibiotic treatment correlates with colonisation by certain uropathogens, whereas the absence of antimicrobial therapy is associated with rapid colonisation of skin flora. Polymicrobial colonisation was common, predominantly involving Gram-positive bacteria. Conclusion Our findings underscore the complexity of bacteriuria in ICU patients, advocating for targeted surveillance and tailored antibiotic approaches to mitigate UTI risk. Insights into antibiotic use and bacterial colonisation are vital for optimising stewardship practices, combating antimicrobial resistance, and enhancing ICU patient outcomes.

The Impact of COVID-19 on Patterns of Fractures Presenting to Pediatric Emergency Departments.

To examine differences in pediatric fracture prevalence, severity, and mechanisms of injury before and during the COVID-19 pandemic. This is a subanalysis of data from a multicenter, cross-sectional study of all injury-related visits to 40 urban pediatric emergency departments (EDs) for children younger than 18 years occurring January 2019-December 2020. ED visits for injuries including fractures were identified by International Classification of Diseases, Tenth Revision codes. Comparative analyses of patient demographics, fracture prevalence, severity, and mechanisms of injury for March 17, 2019, to December 31, 2019 (pre-COVID), versus March 15, 2020, to December 31, 2020 (during COVID), were performed. Fracture-related visits comprised 21.0% (n = 123,684) of all injury visits (n = 589,083) during the study period. There were 16,190 fewer fracture-related visits (-23.2%) in 2020 than 2019. There were differences in the proportion of fracture-related visits by age (P < 0.0001), with increases in children younger than 5 years and decreases in children 5 to 18 years old. There were higher proportions of visits in 2020 among female patients, White children, non-Hispanic children, and those with private insurance (P < 0.0001, respectively). Patients with fractures in 2020 were more severely injured, with higher proportions of hospitalizations (P < 0.0001), intensive care unit admissions (P < 0.0001), deaths (P = 0.007), and higher injury severity scores (P < 0.0001). Fracture mechanisms shifted to more motor vehicle crashes, bicycles, and firearms in 2020 (P < 0.0001). Despite a decrease in fracture-related visits to urban pediatric EDs during the early COVID-19 pandemic, there was an increase in the proportion of ED visits for children younger than 5 years and higher severity injuries. These findings highlight injury epidemiology pattern shifts that occurred during the pandemic. Identifying higher-risk populations for fracture may help guide targeted education and prevention efforts.

The early COVID-19 pandemic period and associated gestational weight gain.

The aim of this study was to investigate if gestational weight gain was altered during the early COVID-19 pandemic period. This a retrospective cohort study evaluating gestational weight gain among individuals delivering during the early COVID-19 pandemic epoch (March 10-December 31,2020) compared to temporally matched pre-pandemic (matched months in 2018 and 2019) controls using electronic medical record data from a large tertiary care hospital. The primary outcome was gestational weight gain defined as a categorical measure representing below, meeting, or above Institute of Medicine (IOM) criteria with further adjustment for gestational age at delivery. The early-pandemic exposure group was also categorized by gestational age at the start period (<14weeks' and 14-20weeks') to assess if duration of exposure affected gestational weight gain risks with the use of multinominal logistic regression. Among 5,377 individuals 3,619 (67.3 %) and 1,758 (32.7 %) were in the pre and early pandemic epochs respectively. Overall, 934 (17.4 %) individuals gained below recommended, 1,280 (23.8 %) met recommendations, and 3,163 (58.8 %) gained above IOM recommended gestational weight gain. Compared to the pre-pandemic epoch, the early pandemic period was not associated with weight gain below (OR 1.06, 95 % Cl 0.89-1.27) or above (OR 1.03, 95 % Cl 0.89-1.19) IOM recommendations. This was also true when the early pandemic group was stratified based on gestational age at the start of the early pandemic period (<14weeks' and 14-20weeks'). This study demonstrated no significant difference in maternal weight gain between pre and early COVID-19 pandemic periods.

Patterns of depression symptoms in relation to stressors and social behaviors during the COVID-19 pandemic among older youth and emerging adults in the United States.

Substantial increases in depression at the outset of the pandemic were previously reported in NCANDA, a longitudinal sample of adolescents and young adults. The current NCANDA study examined depression symptoms before and during the COVID-19 pandemic. It evaluated the influence of stressors and social behavior (e.g., in-person and online socializing) with linear mixed effects models. A strong, positive association between COVID-19-related stressors and depression symptoms was observed. The frequency of in-person socializing did not account for the totality of the changes in depression observed during the early COVID-19 pandemic. It may be that pandemic-related stressors counteracted the benefits of in-person interactions during the early stages of the COVID-19 pandemic. Future studies can continue to elucidate the interactions among psychosocial, genetic, and behavioral factors contributing to depression symptoms in the unprecedented context of the COVID-19 pandemic.

Pediatric emergency mental health presentations during early COVID-19: Comparing virtual and in-person presentations.

Purpose: Increased mental health (MH) needs during the COVID-19 pandemic led to the implementation of a novel pediatric Emergency Department Virtual Care (EDVC) service. Our study aimed to describe the pediatric MH patient population that used EDVC by comparing patient-specific factors of those who obtained services virtually to those seen in-person. Method: This retrospective chart review was conducted at a pediatric hospital in Eastern Ontario. Children and youth (aged 3-17) who received virtual or in-person emergency MH services from May to December 2020 were included. Patient demographics, clinical presentation details and disposition were compared between the virtual and in-person groups. Data was analyzed using descriptive statistics. Results: 1104 youth (96.1%) utilized the in-person ED for MH concerns; 45 (3.9%) used EDVC. In-person youth had a higher level of perceived risk (78.9% vs. 41.9%) and were more likely to present with concerns of depression, suicidal ideation, self-harm, or laceration (46.1% vs. 35.6%). Anxiety/situational crises or behavioural issues were more likely to present virtually. Eight patients (17.8%) were redirected to the ED from EDVC. Conclusions: Several patient-specific factors varied between youth seen in-person or virtually for MH concern. Study results can assist with the design and implementation of virtual MH care platforms.

Auditing citation polarization during the early COVID-19 pandemic

Abstract The recent pandemic stimulated scientists to publish a significant amount of research that created a surge of citations of COVID-19-related publications in a short time, leading to an abrupt inflation of the journal impact factor (IF). By auditing the complete set of COVID-19-related publications in the Web of Science, we reveal here that COVID-19-related research worsened the polarization of academic journals: The IF before the pandemic was proportional to the increment of IF, which had the effect of increasing inequality while retaining the journal rankings. We also found that the most highly cited studies related to COVID-19 were published in prestigious journals at the onset of the epidemic. Through the present quantitative investigation, our findings caution against the belief that quantitative metrics, particularly IF, can indicate the significance of individual papers. Rather, such metrics reflect the social attention given to a particular study.

Negative Emotions and e-Learning Academic Performance of Engineering Students in a Private University

One of the early pandemic COVID-19 effects on the educational sector is that learning activities needto be conducted fully online (e-learning). This circumstance can trigger negative emotions thatcontribute to students’ academic performance. This study aimed to find empirical data regarding therelationship of negative emotions and students academic performance in this particular situation. Thestudy was a cross-sectional quantitative method. Questionnaire of negative emotion (DASS-21)Indonesian version was deployed using google form to students of Industrial Engineering andInformation Systems class of 2020 using convenience sampling. 292 questionnaires were returnedand used. Findings: All three negative emotions (depression, anxiety, and stress) were experiencedby students at different levels. Negative emotions had different correlations to academic performance.There were no significant differences between anxiety and depression to students’ academicperformance (anxiety: F (3) = 2.202, ρ = 0.088, depression: F (2) = 1.397, ρ = 0.249). Two-wayANOVA showed that students who experienced mild stress performed better than those with normalstress category (F (1) = 3.933, ρ = 0.048). Female students significantly had better academicperformance compared to male students (ρ (0.001) &lt; α= 0.05)) and that students experienced mildstress, performed better than those with normal stress category. Managing stress at a moderate levelis beneficial and can be done by media or counseling or other catharsis methods. Further study usinglarger samples from non engineering majors and randomized sampling is needed for generalizationas well as identifying factors that contribute to e-learning performance in a special situation.

Respiratory Syncytial Virus Risk Profile in Hospitalized Infants and Comparison with Influenza and COVID-19 Controls in Valladolid, Spain, 2010-2022.

We aimed to describe the risk profile of RSV infections among children aged ≤ 24months in Valladolid from January 2010 to August 2022 and to compare them with influenza and COVID-19 controls. We conducted a retrospective cohort study of all laboratory-confirmed RSV, influenza, and COVID-19 infections. We analyzed risk factors for RSV hospitalization and severity (length-of-stay ≥ 8 days, intensive-care-unit admission, in-hospital death or readmission < 30days) and compared severity between hospitalized RSV patients vs. influenza and COVID-19 controls using multivariable logistic regression models. We included 1507 patients with RSV (1274 inpatient), 32 with influenza, and 52 COVID-19 controls. Hospitalized RSV (mean age 5.3months) and COVID-19 (4months) were younger than influenza (9.1months) patients. Sixteen percent of patients had RSV within the first month of life. Most infants did not have comorbidities (74% RSV, 56% influenza, and 69% COVID-19). Forty-one percent of patients with RSV and influenza were coinfected vs. 27% COVID-19 (p = 0.04). Among RSV, hospitalization risk factors were prematurity (adjusted OR 3.11 [95% CI 1.66, 4.44]) and coinfection (2.03 [1.45, 2.85]). Risks for higher severity were maternal smoking (1.89 [1.07, 3.33]), prematurity (2.31 [1.59, 3.34]), chronic lung disease (2.20 [1.06, 4.58]), neurodevelopmental condition (4.28 [2.10, 8.73]), and coinfection (2.67 [2.09, 3.40]). Breastfeeding was protective against hospitalization (0.87 [0.80, 0.95]) and severity (0.81 [0.74, 0.88]), while complete vaccination schedule was protective against severity (0.51 [0.27, 0.97]). RSV had 2.47 (1.03, 5.96) higher risk of experiencing any severe outcome compared to influenza and did not show significant differences vs. COVID-19. RSV hospitalizations were more frequent and severe than influenza, while severity was comparable to the early pandemic COVID-19. Currently, both influenza and COVID-19 vaccines are included in the maternal and childhood Spanish immunization schedule between the ages of 6 and 59months. RSV monoclonal antibody is recommended for ≤ 6months but a third of patients were aged 6-24months. Maternal RSV vaccination can protect their children directly from birth and indirectly through breastfeeding.

STI Rates Among High-Risk Youth Undeterred During Early COVID-19 In A HIV Care Clinic

Abstract Background In recent years, the United States has observed increasing rates of sexually transmitted infections (STIs). Rates are highest amongst the teen and young adult age groups. In addition to the immense healthcare costs associated with STIs, long-term sequelae can be severe on the individual level. The risk of infertility is particularly high for those with repeated or prolonged infection. Upon entering the COVID-19 pandemic, it was unclear if the widespread behavioral changes and disruptions in routine care practices to minimize the further spread of COVID-19 would cause an increase or decrease in the United States’ STI rates. This study sought to determine if there was a change in the incidence of STIs during the first year of the COVID-19 pandemic compared to the year prior in a population at high risk for STIs. Methods A retrospective chart review was performed for 330 patients aged 12 to 41 years (mean 20.2 years, median 20 years, standard deviation 3.75 years) with human immunodeficiency virus (HIV) or on pre-exposure prophylaxis (PrEP) to prevent the acquisition of HIV, who presented for preventative and acute care appointments at a multidisciplinary pediatric and young adult HIV Clinic in the year prior to and during the first year of the COVID-19 pandemic (March 22, 2019-March 21, 2021). Utilizing telehealth, rapid COVID-19 screening, and multimodal patient communication, increased efforts were made in this clinic during the pandemic to maintain appropriate STI screening, testing, treatment, and rescheduling of routine visits when appropriate to minimize COVID-19 exposure and spread. Comparisons were made between the two time periods, which evaluated the incidences of individual and overall STIs diagnosed per person-years, STIs per total tests performed, and time to treatment initiation. Results Between one year prior to and the first year during the COVID-19 pandemic, this clinic experienced no statistically significant rate changes of sexually transmitted infections. A non-significant decreased incidence of chlamydia (22 cases per 100 person-years and 18 cases per 100 person-years, respectively) and unchanged rates of gonorrhea (22 cases per 100 person-years and 22 cases per 100 person-years, respectively) and syphilis (16 cases per 100 person-years and 15 cases per 100 person-years, respectively) were observed. The median times to treatment remained largely unchanged. Conclusion This HIV care clinic experienced a decreased chlamydia infection rate, a trend similar to the CDC United States STI data during this time period. In contrast to the nationally reported increased rates of gonorrhea and syphilis, this clinic experienced unchanged rates. The lack of change in our cohort could reflect that the benefits of a multidisciplinary HIV care model persist despite a pandemic that disrupted routine medical care and behavior practices.

Reflecting on the 1775 Mount Gamalama Eruption: Lessons from Indigenous Knowledge for Sustainable Development in Ternate Island, North Maluku Province, Indonesia

The volcanic Molucca islands have provided the world with their precious cloves, which have been highly valued in medicinal properties for millennia. Cloves have antibacterial, antiviral, and analgesic characteristics. They were considered silver bullet cures in medieval epidemics and the early COVID-19 pandemic response. Cloves originated from Ternate Island, the center and regional trade hub of the Molucca Islands. Its cloves had reached Babylonia 4,000 years ago, marking its importance in global trade. Qualitative research was conducted on the 1775 Mount Gamalama eruption's impact on indigenous knowledge development. To confirm the findings, I conducted field visits, key informant interviews, field observations, and a literature review. Tolire Lake is an apparent landmark in Takome village, which has a sacred white crocodile, a java plum hill, a lush forest, stunning landscapes, and an underwater mythical village. The residents are testaments to human resilience, preserving indigenous knowledge and turning it into disaster risk reduction tools. They built settlements on safer ground and designated parts areas for conservation-based tourism. In addition, modern science introduction enhances disaster early warning and alert systems and empowers indigenous communities. Understanding indigenous knowledge and wisdom is critical to building resilience and sustainability through disaster risk reduction (DRR) efforts. Indigenous knowledge produces lessons in environmental protection, social justice, and economic growth. The world can learn from indigenous and scientific knowledge combined to sustain the island, its people, and its prosperity.

Rising out-of-hospital mortality in Canada during 2020‒2022: A striking impact observed among young adults.

Out-of-hospital mortality rates surged during the early COVID-19 pandemic. While expecting a return to pre-pandemic levels, the evolving patterns of out-of-hospital mortality in Canada remain uncertain. We investigated whether these rates returned to pre-pandemic levels. This retrospective study, employing linked administrative data, analyzed out-of-hospital mortality trends among adult residents in Ontario, Alberta, and Nova Scotia. Interrupted time series analysis assessed trends in age- and sex-standardized rates/100,000/quarter during pre-pandemic (April 2014-March 2020) and pandemic periods (April 2020-March 2022), while considering April to June 2020 as the pandemic onset period. Crude mortality rates were also examined, stratified by sex and age groups. Pre-pandemic, Ontario's standardized out-of-hospital mortality rates were rising, while Alberta's and Nova Scotia's remained stable. At the pandemic onset, all provinces experienced significant increases in standardized out-of-hospital mortality rates/100,000 (Ontario: β 14.6, 95% CI [3.97, 25.22]; Alberta: 21.3, 95% CI [9.26, 33.34]; Nova Scotia: 10.5, 95% CI [1.06, 19.88]). During the pandemic, standardized out-of-hospital mortality rates/100,000/quarter remained above pre-pandemic levels, with no significant departure from the increased pandemic onset levels (Ontario: - 1.6, 95% CI [- 3.63, 0.52]; Alberta: 0.45, 95% CI [- 1.47, 2.36]; Nova Scotia: - 0.06, 95% CI [- 2.18, 2.06]). Crude out-of-hospital mortality rates increased most prominently among individuals aged 18 to 45 in Alberta and Ontario, and among males across all provinces. The sustained increase in out-of-hospital mortality, observed from the pandemic's onset, spanning more than 2years, potentially suggests its persistent direct and indirect effects on population health in Canada.

STUDENTS’ REFLECTION ON THEIR PERSONAL AND ACADEMIC LIFE DURING EARLY COVID-19 PANDEMIC

Our world has been transformed dramatically by COVID-19 Pandemic as it affected health, economy, politic, social, education, etc. The aim of this research is discovering students’ reflection toward their personal and academic life during early COVID-19 pandmic situations grounded on three zones, namely fear, learning, and growth zones. This descriptive qualitative survey research used questionnaires to gather the data from 187 freshmen in a university in Palembang. The data were analyzed and interpreted by using a thematic analysis consisting of six steps, namely (1) familiarizing with the data, (2) generating initial codes, (3) searching for themes, (4) reviewing themes, (5) defining and naming themes, and (6) producing the report. The research results show that students reflected on their personal and academic life differently when it was reflected based on the three zones. There were also some factors influencing the reflection, namely the transition between senior high school and university and the typically online learning process demanding autonomous learning. Finally, the research suggests that, alongside the society, students might learn how to move gradually one zone to another in order to overcome this global crisis. Therefore, covid-19 pandemic should be perceived then as a lesson learnt.

Quantifying and Adjusting for Confounding From Health-Seeking Behavior and Health Care Access in Observational Research.

Health-seeking behavior and health care access (HSB/HCA) are recognized confounders in many observational studies but are not directly measurable in electronic health records. We used proxy markers of HSB/HCA to quantify and adjust for confounding in observational studies of influenza and COVID-19 vaccine effectiveness (VE). This cohort study used primary care data prelinked to secondary care and death data in England. We included individuals aged ≥66 years on 1 September 2019 and assessed influenza VE in the 2019-2020 season and early COVID-19 VE (December 2020-March 2021). VE was estimated with sequential adjustment for demographics, comorbidities, and 14 markers of HSB/HCA. Influenza vaccination in the 2019-2020 season was also considered a negative control exposure against COVID-19 before COVID-19 vaccine rollout. We included 1 991 284, 1 796 667, and 1 946 943 individuals in the influenza, COVID-19, and negative control exposure populations, respectively. Markers of HSB/HCA were positively correlated with influenza and COVID-19 vaccine uptake. For influenza, adjusting for HSB/HCA markers in addition to demographics and comorbidities increased VE against influenza-like illness from -1.5% (95% CI, -3.2% to .1%) to 7.1% (95% CI, 5.4%-8.7%) with a less apparent trend for more severe outcomes. For COVID-19, adjusting for HSB/HCA markers did not change VE estimates against infection or severe disease (eg, 2 doses of BNT162b2 against infection: 82.8% [95% CI, 78.4%-86.3%] to 83.1% [95% CI, 78.7%-86.5%]). Adjusting for HSB/HCA markers removed bias in the negative control exposure analysis (-7.5% [95% CI, -10.6% to -4.5%] vs -2.1% [95% CI, -6.0% to 1.7%] before vs after adjusting for HSB/HCA markers). Markers of HSB/HCA can be used to quantify and account for confounding in observational vaccine studies.

Abstract C125: Improving access to genetic counseling and testing for underserved populations through telehealth

Abstract Introduction: A lack of access to genetic counseling for hereditary cancer risk in rural and underserved areas is well-documented and can exacerbate disparities in cancer risk reduction and early detection. Telehealth has the potential to bridge this gap, providing remote access to specialized care. The COVID-19 pandemic accelerated telehealth availability, allowing estimation of the causal effects of shifting to a model of virtual care delivery for genetic counseling services. Methods: The Stanford Cancer Genetic Counseling Clinic provided solely in-person care at two clinical sites (Palo Alto and San Jose, CA) until March 2020, and solely virtual care from April 2020 onward. We performed a regression discontinuity design, allowing outcomes comparison before and after the threshold of early 2020, to evaluate the impact of telehealth genetic counseling on access to care for patients living in areas of higher deprivation. The assignment variable (the exposure measured before versus after the threshold) was the three-month period during which the patients were seen, with the March-May 2020 quarter excluded because of disruption of care during the early COVID-19 pandemic. The primary endpoint was proportion of patients whose primary residence zip code had a state area deprivation index of at least 4. Secondary endpoints included driving distance to the primary clinic location in Palo Alto, CA, insurance type, race/ethnicity, and primary language. Results: The study included N=5,957 patients seen in the Stanford Cancer Genetics Program between January 2017 and February 2020, and N=9,469 patients seen between June 2020 and April 2024. The regression discontinuity analysis revealed a significant discontinuity at the threshold for telehealth in access for patients living in areas of higher deprivation, who accounted for 22% of patients seen just prior to telehealth implementation and 27% just after telehealth implementation, a proportional increase of 21% (p=0.006). Mean driving distance to Palo Alto, CA also increased, from 49 minutes just prior to the threshold to 56 minutes just after (p=0.003). There were no significant differences in insurance type, race/ethnicity, or primary language across the threshold. Conclusion: The implementation of telehealth services at the Stanford Cancer Genetic Counseling Clinic significantly improved access to genetic counseling for patients from areas with higher deprivation, as evidenced by a 21% increase in the proportion of such patients among those seen. These results quantify the effectiveness of telehealth in reducing geographical and socioeconomic barriers to specialized genetic counseling and testing services. Citation Format: Jennifer L.

The impact of the early COVID-19 pandemic on maternal mental health during pregnancy and postpartum

The impact of the early COVID-19 pandemic on maternal mental health during pregnancy and postpartum

Retinal and Corneal OCT Results of Patients Hospitalized and Treated in the Acute Phase of COVID-19.

Objective: This study aimed to assess changes in the morphology of the retina and cornea in patients treated and hospitalized during the acute active phase of SARS-CoV-2 infection. Methods: A total of 24 patients with symptomatic early COVID-19 disease and 38 healthy participants from a control group were enrolled in our study. Among them, 20 received oxygen therapy at flow rates ranging from 1-10 L, while four received high-flow intranasal oxygen therapy (HFNOT). Some patients were treated with other types of therapy, such as Remdesivir, COVID-19 convalescent plasma therapy, or Tocilizumab. In the study, we focused on the analysis of optical coherence tomography (OCT) images of the cornea and retina including corneal thickness, central retinal thickness, retinal nerve fiber layer (RNFL), and optic disc parameters. The measurements were acquired using Spectral-domain OCT REVO FC 130. Results: The analysis did not show significant changes between the examined ophthalmological parameters before and after therapy. Furthermore, there were no detected significant differences between the tested parameters of the retina and cornea in COVID-19-positive patients compared to the control group. Conclusions: No ophthalmological manifestations of COVID-19 disease were observed during the study. Taking into account the results of other publications, the lack of an unambiguous position on this topic requires further research.

Oral SARS-CoV-2 host responses predict the early COVID-19 disease course

Oral fluids provide ready detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and host responses. This study sought to evaluate relationships between oral virus, oral and systemic anti-SARS-CoV-2-specific antibodies, and symptoms. Oral fluids (saliva/throat wash (saliva/TW)) and serum were collected from asymptomatic and symptomatic, nasopharyngeal (NP) SARS-CoV-2 RT-qPCR+ human participants (n = 45). SARS-CoV-2 RT-qPCR and N-antigen detection by immunoblot and lateral flow assay (LFA) were performed. RT-qPCR for subgenomic RNA (sgRNA) was sequence confirmed. SARS-CoV-2-anti-S protein RBD LFA and ELISA assessed IgM and IgG responses. Structural analysis identified host salivary molecules analogous to SARS-CoV-2-N-antigen. At time of enrollment (baseline, BL), LFA-detected N-antigen in 86% of TW and was immunoblot-confirmed. However, only 3/17 were saliva/TW qPCR+ . Sixty percent of saliva and 83% of TW demonstrated persistent N-antigen at 4 weeks. N-antigen LFA signal in three anti-spike sero-negative participants suggested potential cross-detection of 4 structurally analogous salivary RNA binding proteins (alignment 19–29aa, RMSD 1–1.5 Angstroms). At enrollment, symptomatic participants demonstrated replication-associated sgRNA junctions, were IgG+ (94%/100% in saliva/TW), and IgM+ (63%/54%). At 4 weeks, SARS-CoV-2 IgG (100%/83%) and IgM (80%/67%) persisted. Oral and serum IgG correlated 100% with NP+ PCR status. Cough and fatigue severity (p = 0.010 and 0.018 respectively), and presence of weakness, nausea, and composite upper respiratory symptoms (p = 0.037, 0.005, and 0.017, respectively) were negatively associated with saliva IgM but not TW or serum IgM. Throat wash IgM levels were higher in women compared to men, although the association did not reach statistical significance (median: 290 (female) versus 0.697, p = 0.056). Important to transmission and disease course, oral viral replication and persistence showed clear relationships with select symptoms and early oral IgM responses during early infection. N-antigen cross-reactivity may reflect mimicry of structurally analogous host proteins.

Evaluating the tailored implementation of a multisite care navigation service for mental health in rural and remote Australia (The Bridging Study): protocol for a community-engaged hybrid effectiveness-implementation study

BackgroundA dramatic decline in mental health of people worldwide in the early COVID-19 pandemic years has not recovered. In rural and remote Australia, access to appropriate and timely mental health services has been identified as a major barrier to people seeking help for mental ill-health. From 2020 to 2021 a care navigation model, Navicare, was co-designed with rural and remote communities in the Greater Whitsunday Region of Central Queensland in Australia. The Exploration, Preparation, Implementation and Sustainment (EPIS) framework was used to design and guide multiple aspects of a multisite study, The Bridging Study, to evaluate the implementation of Navicare in Australia.MethodsA community-engaged hybrid effectiveness-implementation study design will focus on the tailored implementation of Navicare at three new sites as well as monitoring implementation at an existing site established since 2021. Study outcomes assessed will include sustained access as the co-primary outcome (measured using access to Navicare mental health referral services) and Proctor’s Implementation Outcomes of feasibility, acceptability, appropriateness, adoption, fidelity, implementation cost, and sustainability. Data collection for the implementation evaluation will include service usage data, community consultations, interviews, and workshops; analysed using mixed methods and guided by EPIS and other implementation frameworks. Pre-post effectiveness and cost-consequence study components are embedded in the implementation and sustainment phases, with comparison to pre-implementation data and value assessed for each EPIS phase using hospital, service, and resource allocation data.
