Pediatric Suspected Suicides and Nonfatal Suicide Attempts Reported to United States Poison Control Centers Before and During the COVID-19 Pandemic.

INTRODUCTION: This study investigated the characteristics and compared the trends of pediatric suspected suicide and nonfatal suicide attempts reported to United States (US) poison control centers (PCCs) before and during the first year of the COVID-19 pandemic. METHODS: An interrupted time series analysis using an ARIMA model was conducted to evaluate the trends of suspected suicides and nonfatal suicide attempts among children 6-19 years old reported to the National Poison Data System during March 2020 through February 2021 (pandemic period) compared with March 2017 through February 2020 (pre-pandemic period). RESULTS: The annual number of cases of suspected suicides and nonfatal suicide attempts increased by 4.5% (6095/136,194) among children 6-19 years old during March 2020 through February 2021 compared with the average annual number during the previous three pre-pandemic years. There were 11,876 fewer cases than expected from March 2020 to February 2021, attributable to a decrease in cases during the initial three pandemic months. The average monthly and average daily number of suspected suicides and nonfatal suicide attempts among children 6-12 years old and 13-19 years old was higher during school months than non-school months and weekdays than weekends during both the pre-pandemic and pandemic periods. CONCLUSIONS: There was a greater than expected decrease in the number of suspected suicides and nonfatal suicide attempts among children 6-19 years old reported to US PCCs during the early pandemic months, followed by an increase in cases. Recognizing these patterns can help guide an appropriate public health response to similar future crises.

Pediatric poison exposures reported to United States poison centers before and during the COVID-19 pandemic.

OBJECTIVE: To assess the association of the COVID-19 pandemic with pediatric poison exposures with a focus on unintentional exposures associated with exploratory behavior among children <6 years old. METHODS: An interrupted time series analysis was conducted to evaluate the association of the pandemic with poison exposures among youth <20 years old. Exposures reported to US poison centers (PCs) from 1 March 2017 through 28 February 2020 (pre-pandemic) compared with 1 March 2020 through 28 February 2021 (pandemic) were analyzed. RESULTS: From March 2017 through February 2021, there were 5,244,684 exposures reported to US PCs involving youth <20 years old. There was a 6.0% decrease in poison exposures among youth <20 years old reported to US PCs from pre-pandemic (annual average) to pandemic periods, and there were 93,336 (95% CI: 92,738-93,937) fewer exposures than expected among these individuals during March 2020 through February 2021. Unintentional poison exposures associated with exploratory behavior among children <6 years old accounted for 91.4% of exposures in this age group, and although there were 17,207 (95% CI: 16,951-17,466) fewer of these exposures than expected during the pandemic period, these exposures initially increased during the first two months of the pandemic before decreasing. CONCLUSIONS: The COVID-19 pandemic was associated with changes in poison exposure patterns among youth <20 years old, resulting in a decrease in the number of exposures reported to US PCs during the first pandemic year. Exposure patterns changed with progression from the initial months of the pandemic to later months and varied by age group and reason for exposure. Unintentional poison exposures associated with exploratory behavior among children <6 years demonstrated an increase during the initial first two months of the pandemic before decreasing. Understanding these patterns will help guide an appropriate response to similar future public health events.

What's new in travellers' diarrhoea: updates on epidemiology, diagnostics, treatment and long-term consequences.

BACKGROUND: Travellers' diarrhoea (TD) is the most common clinical syndrome affecting travellers. This narrative review summarizes key discoveries reported in the last two years related to TD and suggests areas for future research. METHODS: A PubMed literature search was conducted for novel data in TD research published between 12 January 2018 and 12 January 2020. Inclusion was based on contribution to epidemiology, aetiology, diagnostics, management and long-term consequences and relevance to public health, discovery and clinical practice. RESULTS: The initial literature search yielded 118 articles. We retrieved 72 and reviewed 31 articles for inclusion. The findings support our understanding that TD incidence varies by traveller group and environment with students and military-travel remaining moderately high risk, and control of food and water in mass gathering events remain an important goal. The growth of culture-independent testing has led to a continued detection of previously known pathogens, but also an increased detection frequency of norovirus. Another consequence is the increase in multi-pathogen infections, which require consideration of clinical, epidemiological and diagnostic data. Fluoroquinolone resistant rates continue to rise. New data on non-absorbable antibiotics continue to emerge, offering a potential alternative to current recommendations (azithromycin and fluoroquinolones), but are not recommended for febrile diarrhoea or dysentery or regions/itineraries where invasive pathogens are likely to cause illness. Recent studies investigated the interaction of the microbiome in TD prevention and consequences, and while discriminating features were identified, much uncertainty remains. The prevalence of extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE) acquisition and carriage is increasing. Finally, continued research documents the post-infectious consequences, whereas mechanisms of reactive arthritis and post-infectious IBS necessitate further investigation. CONCLUSIONS: Globally, TD remains an important travel health issue and advances in our understanding continue. More research is needed to mitigate risk factors where possible and develop risk-based management strategies to reduce antibiotic usage and its attendant consequences.
