Marginalization, Vulnerability and Economic Dynamics in COVID-19

Abstract COVID-19, caused by the coronavirus family SARS-CoV-2 and declared a pandemic in March 2020, continues to spread. Its enormous and unprecedented impact on our society has evidenced the huge social inequity of our modern society, in which the most vulnerable individuals have been pushed into even worse socioeconomic situations, struggling to survive. As the pandemic continues, we witness the huge suffering of the most marginalized populations around the globe, even in developed, high-income latitudes, such as North America and Europe. That is even worse in low-income regions, such as Brazil, where the public healthcare infrastructure had already been struggling before the pandemic. Cities with even more evident social inequity have been impacted the most, leaving the most socioeconomically disadvantaged ones, such as slum residents and black people, continuously inflating the statistics of COVID-19 sufferers. Poverty, marginalization, and inequity have been well-known risk factors for morbidity and mortality from other diseases. However, COVID-19 has deepened our society's wound. It is up to us to heal it up. If we really care for the others and want to survive as a species, we must fight social inequity.

Association of blood viscosity and device-free days among hospitalized patients with COVID-19.

BACKGROUND: Increased estimated whole blood viscosity (eWBV) predicts higher mortality in patients hospitalized for coronavirus disease 2019 (COVID-19). This study assesses whether eWBV is an early predictor of non-fatal outcomes among patients hospitalized for acute COVID-19 infection. METHODS: This retrospective cohort study included 9278 hospitalized COVID-19 patients diagnosed within 48 h of admission between February 27, 2020 to November 20, 2021 within the Mount Sinai Health System in New York City. Patients with missing values for major covariates, discharge information, and those who failed to meet the criteria for the non-Newtonian blood model were excluded. 5621 participants were included in the main analysis. Additional analyses were performed separately for 4352 participants who had measurements of white blood cell count, C-reactive protein and D-dimer. Participants were divided into quartiles based on estimated high-shear blood viscosity (eHSBV) and estimated low-shear blood viscosity (eLSBV). Blood viscosity was calculated using the Walburn-Schneck model. The primary outcome was evaluated as an ordinal scale indicating the number of days free of respiratory organ support through day 21, and those who died in-hospital were assigned a value of -1. Multivariate cumulative logistic regression was conducted to evaluate the association between quartiles of eWBV and events. RESULTS: Among 5621 participants, 3459 (61.5%) were male with mean age of 63.2 (SD 17.1) years. The linear modeling yielded an adjusted odds ratio (aOR) of 0.68 (95% CI 0.59-0.79, p value < 0.001) per 1 centipoise increase in eHSBV. CONCLUSIONS: Among hospitalized patients with COVID-19, elevated eHSBV and eLSBV at presentation were associated with an increased need for respiratory organ support at 21 days. These findings are highly relevant, as they demonstrate the utility of eWBV in identifying hospitalized patients with acute COVID-19 infection at increased risk for non-fatal outcomes in early stages of the disease.

Biochemical markers and NLR levels in COVID-19 infection: In cases with severe pulmonary involvement according to CT score

Objectives: Many studies have been conducted on ferritin, fibrinogen, D-dimer, and neutrophil-lymphocyte ratio (NLR), which are biochemical tests, to determine the severity and prognosis of the disease in the early period of coro-navirus disease 2019 (COVID-19) infection. We aimed to determine the compatibility of these easily accessible and affordable tests with computed tomography (CT) in determining the severity of the disease at an early stage. Methods: This study was carried out retrospectively on 79 patients. In all patients, nasal and pharyngeal swabs were collected and tested for SARS-CoV-2 RNA with reverse transcription-polymerase chain reaction assay. The severity of the disease was determined by computed tomography imaging. According to lung involvement, patients who were found to have a severe infection and divided into the severe group (n=26), and those with milder symptoms were divided into the non-severe group (n=53). The demographic information and laboratory parameters of the patients were obtained from the medical records of the hospital. Analyses were performed using the Statistical Package for the Social Sciencesversion 23.0 for Windows. Results: NLR (8.36±2.45;3.3±2.04 p<0.001), ferritin (ng/mL) (736.1±240.2;374.7±248.4 p<0.001), fibrinogen (mg/mL) (725.7±84.9;416.5±186.1 p<0.001), D-dimer (ug/mL) (3.68±1.42;1.55±1.16 p<0.001), and C-reactive protein (CRP) (mg/ dL) (81.1±11.9;27.9±13.8 p<0.001) levels were found to be significantly higher in the severe group than the non-severe group. In addition, CRP (mg/mL) levelswere positively correlated with NLR (r=0.607 p<0.01). Receiver operator curve analyses were carried out to assess the efficacy of NLR, ferritin, fibrinogen, and D-dimer parameters. Conclusion: These results suggest that NLR, ferritin, fibrinogen, and D-dimer may be useful biomarkers for the early detection of critical cases of COVID-19 infection, paralleling CT findings. These available tests can benefit clinicians in low-resource settings where access to complicated diagnostic methods may be limited. © 2023, Kare Publishing. All rights reserved.

The Nexus Between COVID-19 Factors and Air Pollution.

Background and Objective: There have been significant effects of the current coronavirus-19 (COVID-19) infection outbreak on many facets of everyday life, particularly the environment. Despite the fact that a number of studies have already been published on the topic, an analysis of those studies' findings on COVID-19's effects on environmental pollution is still lacking. The goal of the research is to look into greenhouse gas emissions and air pollution in Bangladesh when COVID-19 is under rigorous lockdown. The specific drivers of the asymmetric relationship between air pollution and COVID-19 are being investigated. Methods: The nonlinear relationship between carbon dioxide ( C O 2 ) emissions, fine particulate matter ( P M 2 . 5 ) , and COVID-19, as well as its precise components, are also being investigated. To examine the asymmetric link between COVID-19 factors on C O 2 emissions and P M 2 . 5 , we employed the nonlinear autoregressive distributed lag (NARDL) model. Daily positive cases and daily confirmed death by COVID-19 are considered the factors of COVID-19, with lockdown as a dummy variable. Results: The bound test confirmed the existence of long-run and short-run relationships between variables. Bangladesh's strict lockdown, enforced in reaction to a surge of COVID-19 cases, reduced air pollution and dangerous gas emissions, mainly C O 2 , according to the dynamic multipliers graph.

Intolerance to uncertainty and self-efficacy as mediators between personality traits and adjustment disorder in the face of the COVID-19 pandemic.

In April 2020, early in the COVID-19 outbreak, governments restricted public gatherings and ordered social distancing. These demands led to challenging adaptations, which in some cases resulted in mental health issues, including adjustment disorder. Guided by the transactional stress model, the current study aimed to examine the relations between personality traits and adjustment disorder in crisis situations and vagueness and the role of intolerance to uncertainty and self-efficacy in these relations. During Israel's first lockdown, 673 Israeli adults completed self-reported e-version questionnaires regarding Big Five personality traits, adjustment disorder, intolerance to uncertainty, self-efficacy, and background variables. The study was designed to examine the association between personality traits and adjustment disorder and the potential mediation of intolerance to uncertainty and self-efficacy in associations. The findings revealed that intolerance to uncertainty and self-efficacy mediated the association between personality traits and adjustment disorder. The results are consistent with the transactional stress model. They shed light on the role of intolerance to uncertainty and self-efficacy as cognitive mechanisms that promote the development of adjustment disorder. Recommendations for future studies and practice are discussed.

Nutritional Intervention for the Treatment and Prevention Against Novel Coronavirus-19

Introduction: The ongoing pandemic of Severe Acute Respiratory Syndrome coronavirus-2 (SARS COV-2) has jeopardized people's health and the global economy. The infection caused by these viruses inflicts immunosuppression and an unprecedented range of symptoms leading to mortality. At this stage, there are no countermeasures or medicines to overcome rapid disease proliferation and aberrant immunological response. Objective(s): The study aims to determine different immunomodulatory therapeutics that could be potential agents to alleviate viral and other lethal infections and possibly rejuvenate immunological and tissue repair response against this disease. Method(s): A review of the literature was performed by screening different scientific databases to procure various immunomodulatory therapies for the treatment of SAR COV-2. Result(s): A comprehensive literature review indicated that different foods rich in vitamins (A-D), selenium and iron can enhance immunological response against various deleterious infections, whereas different nutritious drinks that include hydrogen-enriched water and green tea alleviate inflammation and elicit wound healing properties. Black cumin seeds and Garlic have a myriad of biological activities due to abundant bioactive phytochemicals that play an important role in the elimination of various bacterial and viral infections. Conclusion(s): These foods/supplements are relatively safe to consume and possess high toxicity profile and could be a potential nutritional intervention in order to create adequate immunity within a population to fight against this prevailing infection.Copyright © 2021 Bentham Science Publishers.

Medical student flourishing before and during the COVID-19 pandemic at one U.S. institution.

Introduction: Medical education research often focuses on measuring negative mental states like burnout, rather than focusing on positive states like well-being. Flourishing - a state that includes domains of happiness and mental health - is a way of thinking about well-being that may be relevant to education and research. The purpose of this prospective, observational study was to compare the relationship among flourishing, other well-being measures, and burnout in medical students via a survey administered at two time points.    Methods: We surveyed medical students at one U.S. institution about their flourishing, satisfaction with work-life balance, quality of life, empathic concern, and burnout (emotional exhaustion and depersonalization) before and after the onset of the COVID-19 pandemic. Flourishing was measured using two scores, the Flourish Index (FI) and Secure Flourish Index (SFI), with higher scores indicating greater flourishing. Pre- and post-scores for both measures were compared. Results: 107/585 (18%) medical students responded to the survey and 78/107 (73%) participated in the post survey. At the first time point, respondents reported both a mean FI and SFI 6.7 (SD=1.3); higher levels of flourishing correlated with higher satisfaction with work-life balance (p<.001), higher quality of life (p<.001), and lower levels of burnout (emotional exhaustion p<.001; depersonalization p=.021). SFI scores were higher at the second time point (M=7.1, SD=1.2) than the first (M=6.7, SD=1.3, p=.026). FI, satisfaction with work-life balance, quality of life, empathic concern, and burnout were unchanged at the second time point. Discussion: Like past findings in medical residents, we found medical students' flourishing-as measured by FI and SFI scores-correlated with greater satisfaction with work-life balance, higher quality of life, and lower burnout. In this limited sample, we found flourishing remained largely unchanged after the COVID-19 pandemic onset.

Incidence and medical complications of COVID-19 in the total laryngectomy population: A population-based study.

OBJECTIVES: Laryngeal and hypopharyngeal cancers treated with total laryngectomy (TL) may provide a unique avenue for COVID-19 to infect cancer patients. The objective of this investigation was to identify incidence of COVID-19 infection and potential complications in TL patients. MATERIALS AND METHODS: Data was extracted from TriNetX COVID-19 research network from from 2019 to 2021 and ICD-10 codes were utilized to query for laryngeal or hypopharyngeal cancer, and outcomes of interest. Cohorts were propensity score-matched based on demographics and co-morbidities. RESULTS: A query of active patients in TriNetX from January 1, 2019 to December 31, 2021 identified 36,414 patients with laryngeal or hypopharyngeal cancer out of the 50,474,648 active patients in the database. The overall COVID-19 incidence in the non-laryngeal or hypopharyngeal cancer population was 10.8% compared to 18.8% (p < 0.001) in the laryngeal and hypopharyngeal cancer group. Those who underwent TL had a statistically significant increased incidence of acquiring COVID-19 (24.0%) when compared to those without TL (17.7%) (p < 0.001). TL patients with COVID-19 had a higher risk of developing pneumonia RR (risk ratio) 1.80 (1.43, 2.26), death 1.74 (1.41, 2.14), ARDS 2.42 (1.16, 5.05), sepsis 1.77 (1.37, 2.29), shock 2.81 (1.88, 4.18), respiratory failure 2.34 (1.90, 2.88), and malnutrition 2.46 (2.01, 3.01) when matched with those COVID-19 positive cancer patients without TL. CONCLUSIONS: Laryngeal and hypopharyngeal cancer patients had a higher rate of acquiring COVID-19 than patients without these cancers. TL patients have a higher rate of COVID-19 compared to those without TL and may be at a higher risk for sequalae of COVID-19.

Utilization of COVID-19 positive donors for Heart transplantation and associated short-term outcomes.

BACKGROUND: The safety and efficacy of using COVID-19 positive donors in heart transplantation (HT) are increasingly relevant, but not well established. The present study evaluated the characteristics and utilization of such donors and associated post-HT outcomes. METHODS: All adult (≥18 years old) potential donors and HT recipients in the United States from April 21, 2020 to March 31, 2022 were included. Donor COVID-19 status was defined by the presence (or absence) of any positive test within 21 days of organ recovery. Donor and recipient characteristics and post-HT outcomes, including a primary composite of death, graft failure, and re-transplantation, were compared by donor COVID-19 status. RESULTS: Of 967 COVID-19(+) potential donors, 19.3% (n = 187) were used for HT compared to 26.7% (n = 6277) of COVID-19(-) donors (p < 0.001). Transplanted COVID-19(+) vs COVID-19(-) donors were younger, but otherwise were similar. Recipients of hearts from COVID-19+ vs COVID-19(-) donors less frequently received pre-HT inotropes (24.1% vs 31.7%, p = 0.023) and ventricular assist device therapy (29.7% vs 36.8%, p = 0.040). There were no significant differences in any post-HT outcome by donor COVID-19 status, including the primary composite outcome at 90 days (5.4% vs 5.6%, p = 0.91). Among COVID-19(+) donors, the presence of a subsequent negative test prior to transplant was not associated with posttransplant outcomes. CONCLUSIONS: Our results suggest that carefully selected COVID-19 positive donors may be used for HT with no difference in short-term post-transplant outcomes. Additional data regarding donor and recipient treatments and impact of vaccination should be collected to better inform our use of organs from COVID(+) donors.

Percutaneous debulking of tricuspid valve endocarditis in severe COVID-19 pneumonia after prolonged venovenous extracorporeal membrane oxygenation with right-ventricular support: a case series.

Background: Over the past 2 years, the utilization of venovenous extracorporeal membrane oxygenation (VV-ECMO) for the treatment of coronavirus disease 2019 (COVID-19) acute respiratory distress syndrome (ARDS) has increased. While supporting respiratory function, VV-ECMO requires large-bore indwelling venous cannulas, which risk bleeding and infections, including endocarditis. Case summary: We describe two adults hospitalized for COVID-19 pneumonia who developed ARDS and right-ventricular failure, requiring VV-ECMO and ProtekDuo cannulation. After over 100 days with these devices, both patients developed tricuspid valve vegetations. Our first patient was decannulated from ECMO and discharged, but re-presented with a segmental pulmonary embolism and tricuspid mass. The Inari FlowTriver system was chosen to percutaneously remove both the tricuspid mass and pulmonary thromboembolism. Pathological examination of the mass demonstrated Candida albicans endocarditis in the setting of Candida fungemia. Our second patient developed a tricuspid valve vegetation which was also removed with the FlowTriever system. Pathological examination demonstrated endocarditis consistent with Pseudomonas aeruginosa in the setting of Pseudomonas bacteremia. Both patients experienced resolution of fungemia and bacteremia after percutaneous vegetation removal. After ECMO decannulation and percutaneous debulking, both patients experienced prolonged hospital stays for ventilator weaning and were eventually discharged with supplemental oxygen. Discussion: VV-ECMO and right-ventricular support devices are invasive and create various risks, including bloodstream infection and infective endocarditis. Percutaneous debulking of valvular vegetations associated with these right-sided indwelling devices may be an effective means of infection source control. It is unclear whether prolonged use of VV-ECMO provides a mortality benefit in COVID-19 ARDS.

The Role of Vitamin C in Human Immunity and Its Treatment Potential Against COVID-19: A Review Article.

The outbreak of the COVID-19 pandemic has left clinicians around the world searching for viable prevention and treatment options to use against the virus. The important physiologic properties of vitamin C have been well documented regarding its use by immune cells and its role as an antioxidant. It has previously shown potential as a prophylactic and treatment option for other respiratory viruses, and because of this, there has been intrigue into whether these positive outcomes translate into a cost-effective prevention and treatment option for COVID-19. To this point, there have only been a few clinical trials performed to assess the validity of this notion, with very few showing definitive positive outcomes when vitamin C has been incorporated into prophylactic or treatment protocols to use against coronavirus. When being used to specifically treat the severe complications that arise from COVID-19, vitamin C is a reliable option to treat COVID-19-induced sepsis but not pneumonia or acute respiratory distress syndrome (ARDS). As a treatment option, high-dose therapy has shown flashes of promise in a few studies although investigators in these studies often subject the testing group to multimodal therapies that include vitamin C as opposed to just vitamin C alone. Given the role that vitamin C has shown to uphold regarding the human immune response, it is currently advised for all individuals to maintain a normal physiologic range of plasma vitamin C through diet or supplements for adequate prophylactic protection against the virus. More research with definitive outcomes will be needed before it is recommended to provide high-dose vitamin C therapy to prevent or treat COVID-19.

Gastrointestinal, hepatic and pancreatic manifestations of COVID-19 in children.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is a well-established respiratory tract pathogen. Recent studies in adults and children have shown an increasing number of patients reporting gastrointestinal manifestations of SARS-CoV-2 infection such as diarrhoea, nausea, vomiting and abdominal pain. SARS-CoV-2 RNA can be detected in faeces for an extended period, even after respiratory samples have tested negative and patients are asymptomatic. However, faecal-oral transmission has not yet been proven. In this article, the latest evidence on gastrointestinal, hepato-biliary, and pancreatic manifestations in children with coronavirus disease-19 and multisystem inflammatory syndrome will be analysed.

The Impact of the COVID-19 Pandemic on Makkah City's Health Programs Performance

Background: Coronavirus (Covid-19) is a viral illness caused by a recently discovered coronavirus that began in the Chinese city of Wuhan in December 2019.(1). The impact of this global pandemic affects all social, psychological, and economic aspects of society, and health(1,2). The aim of the Saudi preventive health programs for Community health services was to increase awareness and decrease preventable diseases. This study aimed to assess the impact of the COVID-19 pandemic on key performance indicators of health programs at Makkah Al-Mukarramah City. Material and Methods: This comparative descriptive study was conducted to assess health programs' key performance indicators and statistics before COVID19 in 2019, in comparison with 2020 and 2021. KPI and statistics of health programs collected the data including that on chronic diseases Preventive programs, age categories and healthy life programs.

"Unprecedented Times:" Experiences of Social Work and Public Health Professionals during Times of Public Crises.

Social workers and public health professionals in the U.S. were profoundly impacted by COVID-19, systemic racism, and the 2020 U.S. presidential election. This study examined their external job support, burnout, and job satisfaction in the context of these circumstances. The findings suggest respondents, who had graduate degrees in social work or public health, overemphasized their job satisfaction and underemphasized their burnout. While social work and public health professionals felt satisfied with their labor, not acknowledging burnout limits the amount of support they may access to effectively continue the work. Interestingly, participants who had more administrative functions reported higher job satisfaction scores and lower burnout scores. Traditionally, those in administrative positions have more control over their schedule and work responsibilities. Findings suggest that more training, opportunities for self-care, and discussions about safety and systemic racism are needed in the workplace for social workers and public health professionals.

Psychological Morbidity After COVID-19 Critical Illness.

Survivors of ICU hospitalizations often experience severe and debilitating symptoms long after critical illness has resolved. Many patients experience notable psychiatric sequelae such as depression, anxiety, and posttraumatic stress disorder (PTSD) that may persist for months to years after discharge. The COVID-19 pandemic has produced large numbers of critical illness survivors, warranting deeper understanding of psychological morbidity after COVID-19 critical illness. Many patients with critical illness caused by COVID-19 experience substantial post-ICU psychological sequelae mediated by specific pathophysiologic, iatrogenic, and situational risk factors. Existing and novel interventions focused on minimizing psychiatric morbidity need to be further investigated to improve critical care survivorship after COVID-19 illness. This review proposes a framework to conceptualize three domains of risk factors (pathophysiologic, iatrogenic, and situational) associated with psychological morbidity caused by COVID-19 critical illness: (1) direct and indirect effects of the COVID-19 virus in the brain; (2) iatrogenic complications of ICU care that may disproportionately affect patients with COVID-19; and (3) social isolation that may worsen psychological morbidity. In addition, we review current interventions to minimize psychological complications after critical illness.

Predictors of risky driving among teen drivers with ADHD during U.S. COVID-19 shelter in place orders

Factors associated with continued driving during shelter in place orders have been examined in a community sample of typically developing teen drivers, but not in teens diagnosed with Attention/Deficit-Hyperactivity Disorder (ADHD). Our objective was to examine psychosocial factors that predicted risky driving during shelter in place orders in teens with ADHD, which is important since teens with ADHD are at particular risk for poor driving outcomes. The present study is also novel in that it uses naturalistic data of risky driving rather than self-report of continued driving. Naturalistic in-car data from 56 ADHD participants (M age = 16.875 years, SD = 0.955;55.400 % were male) enrolled in an on-going study were used in the present study. Teens had an average of 26.915 months (SD = 14.343) of driving experience. Risky driving was defined as experiencing an event exceeding 0.600 g-force during the first month of COVID-19 pandemic shelter in place ordinances in Ohio, Kentucky, and Indiana, USA. A hierarchical logistic regression with a post-COVID driving event as the dependent variable was conducted. Baseline ratings of ADHD and oppositional defiant disorder/conduct disorder (ODD/CD) severity were entered in the first step of the model, while anxiety severity and parent behaviors regarding teen driving safety (monitoring and limit setting) were entered in the second step of the model. The first step of the model reached statistical significance (χ2(2, 54) = 7.577, p =.023), with only greater symptoms of ODD/CD significantly predicting a post-COVID driving event (B = 0.144, p =.020). With each point increase in ODD/CD symptoms, there was a 15.5 % increase in the probability of experiencing a high g-force event during COVID-19 restrictions. The model was no longer significant at step 2 when anxiety severity and parent behaviors were added to the model (χ2(3, 55) = 10.97p =.052). We conclude that ODD/CD symptom severity was the strongest predictor of risky driving during COVID-19 restrictions within a sample of teen drivers with ADHD. Study implications may be beneficial for clinicians who work with families of teens with ADHD;suggestions for strategies mitigating this risk are discussed. These findings also have implications for which teens with ADHD may be less positively impacted by other government mitigation strategies such as Graduated Drivers Licensing (GDL) regulations. © 2022

A Statistical Investigation into the COVID-19 Outbreak Spread.

Objective: Coronavirus-19 (COVID-19) outbreaks have been reported in a range of climates worldwide, including Bangladesh. There is less evidence of a link between the COVID-19 pandemic and climatic variables. This research article's purpose is to examine the relationship between COVID-19 outbreaks and climatic factors in Dhaka, Bangladesh. Methods: The daily time series COVID-19 data used in this study span from May 1, 2020, to April 14, 2021, for the study area, Dhaka, Bangladesh. The Climatic factors included in this study were average temperature, particulate matter ( P M 2 . 5 ), humidity, carbon emissions, and wind speed within the same timeframe and location. The strength and direction of the relationship between meteorological factors and COVID-19 positive cases are examined using the Spearman correlation. This study examines the asymmetric effect of climatic factors on the COVID-19 pandemic in Dhaka, Bangladesh, using the Nonlinear Autoregressive Distributed Lag (NARDL) model. Results: COVID-19 widespread has a substantial positive association with wind speed (r = .781), temperature (r = .599), and carbon emissions (r = .309), whereas P M 2 . 5 (r = -.178) has a negative relationship at the 1% level of significance. Furthermore, with a 1% change in temperature, the incidence of COVID-19 increased by 1.23% in the short run and 1.53% in the long run, with the remaining variables remaining constant. Similarly, in the short-term, humidity was not significantly related to the COVID-19 pandemic. However, in the long term, it increased 1.13% because of a 1% change in humidity. The changes in PM2.5 level and wind speed are significantly associated with COVID-19 new cases after adjusting population density and the human development index.

Examination of methadone involved overdoses during the COVID-19 pandemic.

BACKGROUND: The US opioid overdose epidemic continues to escalate. The restrictions on methadone availability including take-home dosing were loosened during the COVID-19 pandemic although there have been concerns about the high street value of diverted methadone. This report examined how fatal overdoses involving methadone have changed over the past two-decades including during the pandemic. METHODS: The CDC's Wide-ranging Online Data for Epidemiologic Research (WONDER) was used to find the unintentional methadone related overdose death rate from 1999 to 2020. Unintentional methadone deaths were defined using the ICD X40-44 codes with only data for methadone (T40.3). Data from the DEA's Automation of Reports and Consolidated Orders System (ARCOS) on methadone overall use, opioid treatment programs use, and pain management use was gathered for all states for 2020 and corrected for population. RESULTS: There have been dynamic changes over the past two-decades in methadone overdoses. Overdoses increased from 1999 (0.9/million) to 2007 (15.9) and declined until 2019 (6.5). Overdoses in 2020 (9.6) were 48.1% higher than in 2019 (t(50) = 3.05, p < .005). The state level correlations between overall methadone use (r(49) = +0.75, p < .001), and opioid treatment program use (r(49) = +0.77, p < .001) with overdoses were positive, strong, and statistically significant. However, methadone use for pain treatment was not associated with methadone overdoses (r(49) = -0.08). CONCLUSIONS: Overdoses involving methadone significantly increased by 48.1% in 2020 relative to 2019. Policy changes that were implemented following the COVID-19 pandemic involving methadone take-homes may warrant further study before they are made permanent.
