Clinical features of COVID-19 rapid antigen test exposures reported by an Australian poisons information centre: a prospective study.

INTRODUCTION: Coronavirus disease COVID-19 rapid antigen tests are a useful tool in detecting infection, and their use has increased in many countries since they became commercially available in late 2021. Some rapid antigen tests contain sodium azide, which can be toxic in small doses. This study aimed to describe the clinical characteristics of exposures to COVID-19 rapid antigen tests. METHODS: This is a prospective study conducted by the New South Wales Poisons Information Centre. From 22 January 2022 to 31 August 2022, rapid antigen test exposures were followed up to obtain outcome information. Data collected included: brand/ingredients, exposure route, demographics, symptoms, and disposition. RESULTS: We recorded 218 exposures in the seven-month study period. Complete follow-up information was available in 75% (n = 164). There were 53 exposures to sodium azide-containing products (35 with follow-up data) and 165 to non-sodium azide-containing products and unknown ingredient exposures (129 with follow-up data). Overall, unintentional exposures predominated (n = 182), and 151 were ingestions. The vast majority (>90%) did not develop symptoms, and all symptoms that developed were mild. Most cases (95%, n = 208) did not require referral to a healthcare facility. CONCLUSIONS: In this prospective series, few patients developed symptoms, regardless of the sodium azide content, likely due to low concentration and low volume within the test kits. However, ongoing toxicovigilance is warranted.

The use of analgesics for intentional self-poisoning: Trends in U.S. poison center data.

In the U.S., intentional self-poisonings with analgesics that are available without a prescription increased from 2000 to 2018. Given concerns regarding mental health outcomes during the COVID-19 pandemic, we examined and compared trends in pediatric and adult intentional self-poisoning with acetaminophen, aspirin, ibuprofen, and naproxen from 2016 to 2021 using the National Poison Data System (NPDS) to see if these trends have continued. We extracted annual case counts of all suspected suicide attempts from intentional poisoning, and of suspected suicide attempts resulting in major effects or death, from the NPDS for non-prescription single ingredient adult formulation acetaminophen, non-prescription single ingredient adult formulation aspirin, single ingredient formulation ibuprofen, and single ingredient formulation naproxen. We enumerated the cases by year, age, and gender. Most cases of intentional self-poisoning within the review period involved acetaminophen and ibuprofen and the 13-19-year-olds constituted the highest proportion of intentional self-poisoning cases across age groups for all four analgesics. Cases involving females predominated cases involving males by 3:1 or greater. The 13-19-year-old age group also represented the largest proportion of cases that resulted in major clinical effects or deaths. An increasing trend in suicide poisoning cases with acetaminophen and ibuprofen was observed in the 6-19-years age group and this trend appeared to exacerbate from 2020 to 2021 corresponding with the start of the COVID-19 pandemic period.

Does the ICU Requirement Score allow the poisoned patient to be safely managed without admission to the intensive care unit? - a validation cohort study.

BACKGROUND: The Intensive care unit (ICU) Requirement Score (IRS) has been defined as identifying poisoned patients on hospital admission who do not require ICU referral, in an effort to reduce health expenses. However, this score has been poorly validated. We aimed to evaluate the IRS in a large cohort of poisoned patients. METHODS: We performed a single-center retrospective cohort study. IRS was calculated using clinical parameters obtained on admission including age, systolic blood pressure, heart rate, Glasgow coma score, intoxication type, co-morbidities (i.e., arrhythmia, cirrhosis, and respiratory insufficiency), and the combination of the intoxication with another reason for ICU admission. We evaluated the ability of IRS < 6 determined on admission to predict the lack of need for ICU treatment, defined as the need for mechanical ventilation, vasopressors, and/or renal replacement therapy in the first 24 h post-admission and/or death during the hospital stay. This score was compared to the usual prognostic scores, i.e., SAPS II and III, SOFA score, and PSS. RESULTS: During the 10-year study period, 2,514 poisoned patients were admitted, 1,011 excluded as requiring ICU treatment on admission, and 1,503 included. Among these patients, 232 met the endpoint whereas only 23/510 patients with IRS < 6 (4.5%) presented the endpoint and one patient died. The area under the curve of the IRS ROC curve was 0.736 (95% confidence interval (CI), 0.702-0.770). The negative predictive value of IRS < 6 was 95% (95% CI, 93-97), sensitivity 89% (95% CI, 85-93), specificity 38% (95% CI, 36-41), and positive predictive value 21% (95% CI, 18-24). IRS performance was similar to those of the other tested scores, which are however not readily available on admission. CONCLUSION: Our data demonstrate the excellent negative predictive value of the IRS, allowing the exclusion of ICU requirements for poisoned patients with IRS < 6. IRS usefulness should be confirmed based on a prospective multicenter cohort study before extensive routine use.

2021 Annual Report of the National Poison Data System© (NPDS) from America's Poison Centers: 39th Annual Report.

ABSTRACTINTRODUCTION: This is the 39th Annual Report of America's Poison Centers' National Poison Data System (NPDS). As of 1 January, 2021, all 55 of the nation's poison centers (PCs) uploaded case data automatically to NPDS. The upload interval was 4.87 [4.38, 8.62] (median [25%, 75%]) minutes, effectuating a near real-time national exposure and information database and surveillance system. METHODS: We analyzed the case data tabulating specific indices from NPDS. The methodology was similar to that of previous years. Where changes were introduced, the differences are identified. Cases with medical outcomes of death were evaluated by a team of medical and clinical toxicologist reviewers using an ordinal scale of 1-6 to assess the Relative Contribution to Fatality (RCF) of the exposure. RESULTS: In 2021, 2,851,166 closed encounters were logged by NPDS: 2,080,917 human exposures, 62,189 animal exposures, 703,086 information requests, 4,920 human confirmed nonexposures, and 54 animal confirmed nonexposures. Total encounters showed a 14.0% decrease from 2020, and human exposure cases decreased by 2.22%, while health care facility (HCF) human exposure cases increased by 7.20%. All information requests decreased by 37.0%, medication identification (Drug ID) requests decreased by 20.8%, and medical information requests showed a 61.1% decrease, although these remain about 13-fold higher than before the COVID-19 pandemic. Drug Information requests showed a 146% increase, reflecting COVID-19 vaccine calls to PCs. Human exposures with less serious outcomes have decreased 1.80% per year since 2008, while those with more serious outcomes (moderate, major or death) have increased 4.56% per year since 2000.Consistent with the previous year, the top 5 substance classes most frequently involved in all human exposures were analgesics (11.2%), household cleaning substances (7.49%), cosmetics/personal care products (5.88%), antidepressants (5.61%), and sedatives/hypnotics/antipsychotics (4.73%). As a class, antidepressant exposures increased most rapidly, by 1,663 cases/year (5.30%/year) over the past 10 years for cases with more serious outcomes.The top 5 most common exposures in children age 5 years or less were cosmetics/personal care products (10.8%), household cleaning substances (10.7%), analgesics (8.16%), dietary supplements/herbals/homeopathic (7.00%), and foreign bodies/toys/miscellaneous (6.51%). Drug identification requests comprised 3.64% of all information contacts. NPDS documented 4,497 human exposures resulting in death; 3,809 (84.7%) of these were judged as related (RCF of 1-Undoubtedly responsible, 2-Probably responsible, or 3-Contributory). CONCLUSIONS: These data support the continued value of PC expertise and the need for specialized medical toxicology information to manage more serious exposures. Unintentional and intentional exposures continue to be a significant cause of morbidity and mortality in the US. The near real-time status of NPDS represents a national public health resource to collect and monitor US exposure cases and information contacts. The continuing mission of NPDS is to provide a nationwide infrastructure for surveillance for all types of exposures (e.g., foreign body, infectious, venomous, chemical agent, or commercial product), and the identification and tracking of significant public health events. NPDS is a model system for the near real-time surveillance of national and global public health.

Ivermectin exposures reported to the Poisons Information Helpline in South Africa during the COVID-19 pandemic.

BACKGROUND: Ivermectin is an antiparasitic drug that has shown in vitro activity against COVID­19. Clinical studies supporting ivermectin for COVID­19 prevention and treatment are conflicting, with important limitations. Public support for ivermectin is significant, with extensive off-label use despite the conflicting views on its efficacy. Ivermectin tablets and injectable formulations are not registered in South Africa for human use by the South African Health Products Regulatory Authority. The National Department of Health does not currently recommend the use of ivermectin for COVID­19. OBJECTIVES: To describe cases of ivermectin exposure reported to the Poisons Information Helpline of the Western Cape (PIHWC) before and after publication of the drug's in vitro activity against SARS-CoV-2. METHODS: In a retrospective review, ivermectin-related calls reported to the PIHWC from 1 June 2015 to 30 June 2020 (period 1) were compared with calls received from 1 July 2020 to 31 July 2021 (period 2), dichotomised according to the first publication indicating ivermectin activity against SARS-CoV-2. RESULTS: Seventy-one cases were screened, and 65 were included for analysis; 19 cases were reported during period 1 and 46 during period 2. During period 2, 25 ivermectin cases (54.3%) were related to COVID­19 use. Of these, 24 cases (52.2%) involved veterinary preparations, 3 (6.5%) human preparations and 19 (41.3%) unknown preparations. Fourteen cases (73.7%) during period 1 and 30 (65.2%) during period 2 were reported to be symptomatic. The most common organ systems involved were the central nervous (n=26 cases; 40.0%), gastrointestinal (n=18; 27.7%), ocular (n=9; 13.8%) and dermatological (n=5; 7.7%) systems. CONCLUSION: Ivermectin-related exposure calls increased during study period 2, probably as a result of ivermectin being used as preventive and definitive therapy for COVID­19 in the absence of robust evidence on efficacy, dosing recommendations or appropriate formulations.

Changes in Poison Center Calls for Intentional Exposure During Public Health Emergencies: COVID-19 and Winter Storm Uri in Dallas County, Texas.

OBJECTIVE: This study aimed to: (1) explore changes in the volume of calls to poison control centers (PCs) for intentional exposures (IEs) in Dallas County, Texas, overall and by gender and age, and (2) examine the association between 2 different public health emergencies (PHEs) and changes in IE call volume. METHODS: PCs categorize calls they receive by intentionality of the exposure, based on information from the caller. We analyzed data on PC calls categorized as intentional in Dallas County, Texas, from March 2019 - April 2021. This period includes the COVID-19 pandemic declaration (March 2020), a surge in COVID-19 cases (July 2020), and Winter Storm Uri (February 2021). Changes in IE call volume (overall and by age and gender), were explored, and interrupted time series analysis was used to examine call volume changes after PHE onset. RESULTS: The summer surge in COVID-19 cases was associated with 1.9 additional IE calls/day (95% CI 0.7 to 3.1), in the context of a baseline unadjusted mean of 6.2 calls per day (unadjusted) before November 3, 2020. Neither the pandemic declaration nor Winter Storm Uri was significantly associated with changes in call volume. Women, on average, made 1.2 more calls per day compared to men during the study period. IE calls for youth increased after the pandemic declaration, closing the longstanding gap between adults and youth by early 2021. CONCLUSIONS: Changes in IE call volume in Dallas County varied by gender and age. Calls increased during the local COVID-19 surge. Population-level behavioral health may be associated with local crisis severity.

Hand sanitizer-related calls at the National Poisons Information Centre, India during the lockdown period of the Covid-19 pandemic.

Background Hand sanitizer (HS) has been increasingly used during the Covid-19 pandemic. We compared the telephonic calls received by the National Poisons Information Centre (NPIC), New Delhi, India, related to its unsafe exposure and inappropriate use during the lockdown and prelockdown periods. Methods We analysed and compared telephonic call records of 3 months of pre-lockdown and 3 months of the lockdown and HS-related calls in different age groups and zones during these periods. Results The centre received 4000 calls; of these 1583 (40%) were related to household products of which only 63 (4%) were related to HS. There was an 8-fold increase in the number of calls received at the NPIC during the lockdown compared to the pre-lockdown period seeking medical attention following unsafe exposure or inappropriate use of HS. More calls were received from the south and north zones and, in the majority of these cases, HS was ingested accidentally. In some cases, HS was ingested intentionally for suicide during the lockdown. Conclusions Our study shows that unsafe exposure of HS is common under conditions of stress as seen during the lockdown period of the Covid-19 pandemic. It should be kept out of reach of small children. Further, providing psychological help and counselling to older age groups under conditions of stress are important issues of concern.

Outcomes from integrating anti-cervical cancer teachings into the curriculum of high schools in a South-Eastern Nigerian State.

BACKGROUND: Quests for the global elimination of cervical cancer and its related SDG goals by 2030 are achievable if realistic approaches for improving outcomes in LMICs are entrenched. Targeting teenage high schoolers in these countries, which largely lack universally-affordable anti-cervical cancer measures, can be a game-changer. This paper evaluates a 2019 Harvard-endorsed measure that integrated relevant teachings into the curricula of some Nigerian high schools, in what was a global-first. METHOD: A 12-month, quasi-experimental (pre-and-post-tests) research that evaluated the impact of the above initiative on three public schools randomly selected from a pool of 261 in South-east Nigeria. The intervention was "exposure" to anti-cervical teachings, which included "repetitions" and "examination/assessments" designed to enhance "engagement". Both genders were among the 2,498 recruited participants. Data collections with questionnaires were at three different intervals over 12 months. RESULTS: At Phase-1 (baseline), there were 1,699 (68.0%) responses, while Phases 2 (one-month post-intervention) and 4 (12-month post-intervention) had 1,797 (71.9%) and 500 (20.0%) responses, respectively. COVID-19 lockdowns washed out Phase-3 (six-month post-intervention). The majority in all groups were aged 15-19 years. Males dominated in phases 1 (55.9%) and 2 (67.3%), and females (65.6%) in Phase 4. Overall, there were increased knowledge on "General Awareness", "HPV Vaccinations", "Risk Factors" and "Symptoms", particularly between Phases 2 and 1. Levels at Phase-4 were higher than at Phase-2, with the exception of "Pap Smears", as knowledge gained in half of its assessing items became negative (reversed) at Phase-4. These observed changes were non-different between gender, age groups, and classes of high schools. Relative to Phase 2, knowledge changes at Phase-4 for questions associated with established myths ("spiritual attacks"; OR 0.39; CI 0.29-0.52 and "enemy poisons"; OR 0.49; CI 0.37-0.65) were reversed, even though they were originally increased significantly between Phases 2 and 1. CONCLUSION: Anti-cervical cancer enlightenment interventions to teenage high school students were largely effective, but appears guaranteed if engagement-enhancing measures are maintained over time. Extra efforts should be put into debunking prevailing myths.

Military medical research in the IDF: an array of fields and interests.

BACKGROUND: War is as old as history. Some may say it is older. The first Biblical war, dated 1880-1875 BCE, is depicted in the book of Genesis between nine kings in the vicinity of the Jordan river near Jericho. By the end of the war, Abraham (Abram) gets involved in saving his nephew Lot. In addition to war, military medicine also has its roots in historical times. Hippocrates (460-377 BCE), the father of medicine, derived his medical knowledge from the battlefield, and Sushruta [1], the father of plastic surgery, mentioned the physician's preventive role in noting environmental hazards: "A common practice of the enemy is to poison the wells on the roadside, the articles of food, the shades of trees, and the fuel and forage for cattle; hence, it is incumbent on a physician marching with the troops to inspect, examine, and purify these before using any of them, in case they are poisoned." The Greeks stated new ideas of military health, pointing to fitness promotion, gymnastics, and healthy diets to prevent illness. Over the centuries, from Alexander the Great to Napoleon's army and wars in the 20th century, military conflicts have led to the death of hundreds of millions of people from trauma and war-related disease. Amazingly analyses of the 18th and 19th centuries have shown that 80% of the soldiers died from disease, and historians and military personnel agree that during armed conflicts in known history, only a minority of soldiers perished by the sword. In Israel, the Israel Defense Forces-Medical Corps (IDF-MC) holds a unique position embedded in military and civilian national medicine. All medical personnel (e.g., physicians, nurses, technicians, veterinarians) who work in the IDF-MC receive their diplomas from civilian universities, train in civilian hospitals, and continue to practice in the national health system. The majority of these professionals continue to work in different civilian medical platforms in Israel after finishing their mandatory service. The IDF-MC's primary mission is to provide optimal medical care to IDF soldiers at all times (including wartime), to prevent disease and promote health, advance military medicine, and aid the civilian sector as ordered by the Government of Israel. In this special issue of Israel Medical Association Journal (IMAJ) is to expose readers to the continuous efforts of the IDF-MC to fulfill its mission by promoting research in multiple medical fields, including trauma, ambulatory care, health administration. In addition, in this issue of IMAJ, authors discuss the unique collaboration with the civilian system during the coronavirus disease 2019 (COVID-19) pandemic. Trauma and trauma-related injuries are the main focus of military medical research. Ben-Avi and colleagues [2] described outcomes of emergent exploratory thoracotomies on military casualties and addresses parameters that may impact the survival of these casualties. Minervini [3] further discussed the issue. Bez et al. [4] researched the impact of isolated versus non-isolated traumatic brain injuries on injury identification and decision-making by care providers in austere scenarios. Tsur and co-authors [5] described the characteristics of a unique type of terror attack: vehicle ramming. Additional examples of treatments provided in the military prehospital arena were analyzed by Nakar and colleagues [6] who discussed how to assess pain medications administered to trauma casualties in the past two decades by IDF-MC care providers. Rittblat et al. [7] further described the use of freeze-dried plasma, a blood component used in the prehospital arena and administered via intraosseous vascular access. The IDF-MC is a continuously changing organization emphasizing the adoption of advanced technologies and devices. Chen et al. [8] presented a blinded study on the use of point-of-care ultrasound and remote telementored ultrasound by inexperienced operators, and Sorkin et al. [9] described the BladeShield 101: a novel device for the battlefield designed to continuously measure vital signs and medical treatment provided and to transfer data through roles of care. In this special issue of IMAJ, authors also discusse gender-related aspects at the core of medical treatment. Segal et al. [10] examined whether missed injuries were related to the medical provider's gender, while Gelikas et al. [11] assessed whether treatment with analgesia was associated with casualty gender in the military prehospital trauma setting Over the past two and a half years, the COVID-19 pandemic has been a significant part of our lives. During these years, medical systems and teams throughout Israel and around the world struggled to adapt to this new disease and save lives fighting the pandemic. Geva et al. [12] and Shental et al. [13] discussed the impact of COVID-19 on the IDF medical system, lessons learned during the outbreak, and effects of different diseases during these times on medical treatment provided by the IDF to soldiers.

Adolescent US Poison Center Exposure Calls During the COVID-19 Pandemic.

PURPOSE: The objective of this study was to evaluate trends and characteristics in adolescent poison center (PC) exposure calls before and during the COVID-19 pandemic. METHODS: A retrospective review of PC calls for adolescents aged 13-17 years from January 1, 2018 through June 30, 2021. RESULTS: During the pandemic, US PCs had a higher proportion of adolescent exposure calls managed in a healthcare facility (71.9% vs. 67.4%) and hospital admissions (27.2% vs. 25.7%) than prior to the pandemic. There was a higher proportion with suicide intent (55.8% vs. 48.8%), moderate/major clinical effects (22.8% vs. 20.1%), and deaths (0.07% vs. 0.05%). Monthly calls significantly increased from 30 calls/month to 204 calls/month (p < .001). The slope of hospital admissions significantly increased (0.19% per month, p < .001) during the pandemic. DISCUSSION: During the COVID-19 pandemic, US PCs observed an increase in adolescent suicidal intent exposure calls with more severe outcomes, hospitalizations, and deaths.

Changes in unintentional cannabis exposures in children 6 months to 5 years reported to United States poison centers during the first nine months of the coronavirus-19 pandemic.

INTRODUCTION: Almost half of exposures reported to United States (US) poison centers are exploratory ingestions in children under the age of 5 years. Pediatric cannabis exposures reported to US poison centers have risen over the last twenty years, with greater increases in the last 5 years. In 2020, the Coronavirus disease 2019 (COVID-19) pandemic resulted in widespread stay-at-home orders and subsequent changes in work, education, and daycare. This study describes the changes in pediatric cannabis exposures during the first nine months of the COVID-19 pandemic relative to the three years before the pandemic. METHODS: Cases were identified from the National Poison Data System. Inclusion criteria was unintentional cannabis exposure in children aged 6 months to 5 years between January 1, 2017 and December 31, 2020. Analysis was performed with segmented regression of interrupted time series analysis comparing January 2017-March 2020 (pre-COVID-19) to April 2020-December 2020 (COVID-19 period). Autocorrelation was assessed using Dubin-Watson test. RESULTS: There were 7,679 unintentional pediatric exposures from January 1, 2017 through December 31, 2020. There was a significant increase of 3.1% per month during the pre-COVID-19 period (p < .0001). A statistically significant immediate increase in number of exposures per month occurred in April 2020 (58.4%; p < .0001). The slope in the COVID-19 period was -0.01% (p = .99). No autocorrelation was detected. DISCUSSION AND CONCLUSIONS: Unintentional cannabis exposures in children aged 6 months to 5 years reported to United States poison centers increased significantly after the initial COVID-19 stay-at-home orders. This trend may be associated with COVID-19 quarantines, increased time children are spending at home, increased availability of cannabis products in homes, or other reasons. Future efforts should evaluate specific factors that resulted in the observed increases in pediatric exposures.

A Yeast-Based Screening System for Differential Identification of Poisons and Suppressors of Human Topoisomerase I.

BACKGROUND: Inhibition of human topoisomerase I (TOP1) by camptothecin and topotecan has been shown to reduce excessive transcription of PAMP (Pathogen-Associated Molecular Pattern)-induced genes in prior studies, preventing death from sepsis in animal models of bacterial and SARS-CoV-2 infections. The TOP1 catalytic activity likely resolves the topological constraints on DNA that encodes these genes to facilitate the transcription induction that leads to excess inflammation. The increased accumulation of TOP1-DNA covalent complex (TOP1cc) following DNA cleavage is the basis for the anticancer efficacy of the TOP1 poisons developed for anticancer treatment. The potential cytotoxicity and mutagenicity of TOP1 targeting cancer drugs pose serious concerns for employing them as therapies in sepsis prevention. METHODS: In this study we set up a novel yeast-based screening system that employs yeast strains expressing wild-type or a dominant lethal mutant recombinant human TOP1. The effect of test compounds on growth is monitored with and without overexpression of the recombinant human TOP1. RESULTS: This yeast-based screening system can identify human TOP1 poisons for anticancer efficacy as well as TOP1 suppressors that can inhibit TOP1 DNA binding or cleavage activity in steps prior to the formation of the TOP1cc. CONCLUSIONS: This yeast-based screening system can distinguish between TOP1 suppressors and TOP1 poisons. The assay can also identify compounds that are likely to be cytotoxic based on their effect on yeast cell growth that is independent of recombinant human TOP1 overexpression.

Exposure to hand sanitisers and other cleaning products in Victoria, Australia during the COVID-19 pandemic.

BACKGROUND: In response to the COVID-19 pandemic, there was increased promotion and use of topical antiseptics (especially hand sanitisers) and cleaning products to reduce transmission of the SARS-CoV-2 virus. This study describes unintentional exposures (oral or ocular) to these substances by children during the first year (2020) of the COVID-19 pandemic compared to the previous year (2019). METHODS: This was a retrospective observational study of unintentional exposures reported to the Victorian Poisons Information Centre for the period 1 January 2019 to 31 December 2020. Substances included topical antiseptics (including hand sanitisers), bleach, multipurpose cleaners, disinfectants and high-percentage ethanol products. We analysed data for two age groups; under 5 years and 5 to 14 years. RESULTS: Oral exposures (ingestion or buccal) to topical antiseptics increased from 435 in 2019 to 882 in 2020 in the under 5 age group, with peak call numbers in 2020 coinciding with peaks in active COVID-19 daily case numbers. Oral exposures in older children (5-14 years) were lower (23 and 77 in 2019 and 2020, respectively). No children had moderate or severe symptoms at the time of the call to the Poisons Centre. Ocular exposures to topical antiseptics more than doubled from 2019 to 2020 (from 20 to 53 among children under 5 years, and 8 to 18 in older children). The majority of children with ocular exposure presented with mild symptoms; one had moderate symptoms. Changes in exposures to disinfectants, bleach and cleaners were smaller and not consistent with peaks in active COVID-19 cases. CONCLUSIONS: Unintentional oral exposures to topical disinfectants (mainly hand sanitiser) by young children increased during the COVID-19 pandemic and were more prevalent during periods of increased COVID-19 cases. While there were no cases of severe harm identified, the high number of exposures suggests that appropriate use and storage of hand sanitisers should be promoted.

Heroin and fentanyl overdose deaths among cases age 50+ in the National Poison Data System, 2015-2020.

CONTEXT: Illicit opioid use and heroin treatment admissions among individuals age 50+ have increased. Little research has, however, examined correlates of illicit opioid overdose deaths in this age group before or during the COVID-19 pandemic or the healthcare services used in these cases. METHODS: The sample included illicit opioid (heroin, fentanyl, or other synthetic, nonpharmaceutical opioids) poisoning cases age 50+ (N = 5576) in the National Poison Data System (NPDS), 2015-2020. Using descriptive statistics and logistic regression models, we report changes in overdose death rates during the study period and associations of death with healthcare service use, naloxone administration, and clinical and demographic characteristics. RESULTS: The 6-year average overdose death rate from illicit opioids among those age 50+ was 2.9%, increasing from 1.4% in 2015 to 4.0% in 2019 and 3.6% in 2020. Logistic regression results showed that exposure year was not a significant factor in the odds of overdose death; however, odds were significantly higher among cases that were not managed at any healthcare facility (HCF) (adjusted odds ratio [AOR] = 4.60, 95% confidence interval [CI] = 3.19-6.63) and lower among those who received naloxone therapy (AOR = 0.64, 95% CI = 0.45-0.92). The odds of death were also higher among cases involving exposure at own or another's home and co-use of prescription opioids, alcohol, and other illicit drugs. CONCLUSIONS: Although the NPDS did not show increases in illicit opioid overdose death rates among cases age 50+ in 2020 compared to 2019, overdose deaths were greater among cases that were not managed at HCF and did not receive naloxone therapy. Many appear to have died before they received any intervention to prevent death. Improved access to healthcare services and social support and access to naloxone therapy for older adults with opioid use problems are needed.

"Poison" or "protection"? A mixed methods exploration of Australian parents' COVID-19 vaccination intentions.

OBJECTIVE: The success of COVID-19 vaccination programs relies on community attitudes, yet little is known about parents' views. We aimed to explore the reasons behind Australian parents' vaccine intentions for themselves and for their children. METHOD: This mixed methods study relates to Wave 13 (January 2021) of a longitudinal study of Australian parents' experiences during COVID-19 and contained 1094 participants (83% mothers). We used multinomial logistic regression to understand demographic predictors of vaccine intention, and a descriptive template thematic analysis to analyse open-ended questions about parents' reasons for vaccine intentions for themselves and their children. RESULTS: 64% of Australian parents intend on vaccination, 26% are unsure and 9% intend to decline; 48% intend to vaccinate their children, 38% are unsure, and 14% intend to decline. Relative to those intending to vaccinate, parents unsure (OR = -0.63, 95% CI: 0.46, -0.84, p = .002) or not intending (OR = -0.41, 95% CI: 0.24, 0.67 p < .001) to vaccinate were more likely to have lower trust in doctors. Similar predictors emerged for parents who did not intend to vaccinate their children (OR = 0.47, 95% CI: 0.31, 0.70, p < .001). Qualitative data indicated that many parents had not made a firm decision, including a lack of alignment between intentions and reasons. For example, parents who said 'yes' to vaccination, often then expressed hesitance and a focus on risks in their written response. Reasons for hesitancy for themselves included concerns about testing, side effects, and long-term outcomes. Similar themes were present for children, but parents expressed a strong desire to protect their children, and an eagerness for health information. CONCLUSION: Based on prior research and the themes identified here, a multipronged campaign that includes education/promotion, good access to vaccines and role models, is likely to support parents to make informed decisions regarding COVID-19 vaccination.

e-Health for COVID-19 Epidemic: The Arizona Poison and Drug Information Center Experience.

Background: A significant challenge of the COVID-19 epidemic was the dissemination of accurate and timely information to the public, health care providers, and first responders. We describe the expansion of the Arizona Poison and Drug Information Center (APDIC) to fill such a need for residents of Arizona. Methodology: The original mission of the APDIC was recognition and management of chemical exposure, poisoning, envenomation, and drug-related medical problems. In response to COVID-19, APDIC expanded its personnel and facilities to accommodate telephone calls and teleconsults regarding COVID-19. Thirteen different topics dealing with COVID-19 were addressed and tracked and included: testing information, isolation, prevention, personal protective equipment, travel, vaccines, therapies, antibody testing, contact tracing, exposure to the virus and what to do in businesses, at work or at school regarding isolation and quarantine. Results: Responding to the public health needs, APDIC accepted >320,000 telephone calls and completed 48,346 teleconsults from March 3, 2020 to March 3, 2021. This represented a 15-fold increase in calls and twice the number of consults over 2019. Upon release of the vaccine, calls increased sharply with >7,000 calls in 1 day (February 7, 2021). Conclusion: In conclusion, the APDIC, rapidly expanded to address urgent public health information needs surrounding COVID-19 while still accomplishing its founding mission.

Declaring Racism a Public Health Crisis in the United States: Cure, Poison, or Both?

Declaring racism a public health crisis has the potential to shepherd meaningful anti-racism policy forward and bridge long standing divisions between policy-makers, community organizers, healers, and public health practitioners. At their best, the declarations are a first step to address long standing inaction in the face of need. At their worst, the declarations poison or sedate grassroots momentum toward anti-racism structural change by delivering politicians unearned publicity and slowing progress on health equity. Declaring racism as a public health crisis is a tool that must be used with clarity and caution in order to maximize impact. Key to holding public institutions accountable for creating declarations is the direct involvement of Black and Indigenous People of Color (BIPOC) led groups and organizers. Sharing power, centering their voices and working in tandem, these collaborations ensure that declarations push for change from the lens of those most impacted and authentically engage with the demands of communities and their legacies. Superficial diversity and inclusion efforts that bring BIPOC people and organizers into the conversation and then fail to implement their ideas repeat historical patterns of harm, stall momentum for structural change at best, and poison the strategy at worst. In this paper we will examine three declarations in the United States and analyze them utilizing evaluative criteria aligned with health equity and anti-racism practices. Finally, we offer recommendations to inform anti-racist public health work for meaningful systematic change toward decentralization and empowerment of communities in their health futures.

The National Institute of Health and the Italian Poison Centers Network: results of a collaborative study for the surveillance of exposures to chemicals.

Background: The Public Health Surveillance Systems are essential to improve and protect public health, as highlighted by the World Health Organization. According with this consideration, a systematic collaboration between the National Institute of Health and the Poison Centers of Northern, Central and Southern Italy was established. Its aim was to improve the national network for the surveillance of dangerous exposures to chemicals. The developed network provided harmonized data essential for evidence-based interventions and significantly ameliorated the data flow between the Poison Centers and the Central Health Institutions. Methods: The improvement of the system was obtained through several actions, such as the development of the "Online Surveillance Card" for the detection of sentinel events in real time and the harmonization of the data collection flow, including the product categorization according to the European Product Categorization System. Data analysis was carried out by Microsoft's IBM SPSS Statistics version 26, Access and Excel. Results: Important information was obtained, regarding also exposures to chemicals and their management in pediatric populations. The surveillance network was proved effective not only under "normal" conditions but also to promptly monitor changes during exceptional health emergencies, such as the COVID-19 pandemic. During the 2020 lockdown the surveillance system registered a significant increase in the frequency of exposures to disinfectants (p-value=0.002), an evidence that highlighted the need of tailored intervention. Conclusions: This Italian Project model proves to be reliable and suitable to be transferred to other European countries, in order to realize an European Poison Centers' Network, able to overcome unsolved health problems and to globally improve the "evidence-based" prevention of exposures to chemicals.

Despair in the time of COVID: A look at suicidal ingestions reported to the California Poison Control System during the pandemic.

BACKGROUND: Despite concern that the global pandemic will worsen depression and suicide rates, there remain little data on its actual effect. The purpose of this study was to determine the effect of the COVID-19 pandemic on suicidal ingestions reported to the California Poison Control System (CPCS). METHODS: This was a cross-sectional comparison of suicidal ingestions reported to the CPCS during the 2020 COVID-19 pandemic compared to suicidal ingestions reported during the same period in 2018 and 2019. RESULTS: The CPCS received 19,607 call for suicidal ingestions during the study periods, of which 13,800 were in the pre-COVID era (2018 and 2019) and 5,807 were in the COVID era. The median (IQR) number of suicidal ingestions per month decreased from 2,286 (2,240-2,364) to 1,940 (1,855-2,045; p = 0.02). This decrease was consistent and significant across all age groups except those age 70 or older. Ingestions without adverse events decreased by 101 cases/month (95% confidence interval [CI] = 136.8 to 65; p = 0.0003), minor outcomes decreased by 156.6 cases/month (95% CI = 226.2 to 87.1; p = 0.001), and moderate outcomes decreased by 96 cases/month (95% CI = 143.9 to 48.1; p = 0.00021). Major outcomes decreased from 793 (4.99%) cases in the pre-COVID era to 315 (4.60%) cases in the COVID era (risk ratio = 0.92, 95% CI = 0.81 to 1.05). The number of deaths decreased by 3.7 cases/month (95% CI = -8.3 to 0.92, p = 0.10). CONCLUSIONS: Despite concern for worsening suicidality, calls regarding suicidal ingestions to the nation's largest poison control center decreased during the COVID era compared to the pre-COVID era. This study provides evidence that the pandemic's effects on modern society remain difficult to predict. Further effort is needed to understand how pandemic will affect American's mental health.
