Background: The COVID-19 pandemic reportedly had a significant impact on drug and alcohol use. In this article, we determine positivity rates for urine drugs of abuse and blood alcohol in 5 emergency departments (ED) in the greater Boston metropolitan area over a 4-year period (pre-, during, and post-COVID-19 pandemic).
Methods: Positivity rates for the urine drug screening (UDS) panel and blood alcohol concentration (>80 mg/dL; over the legal limit in MA) were calculated in patients presenting to one of the 5 ED (2 academic hospitals in Boston, MA and 3 community hospitals outside Boston, MA) during each of the 4 different time periods: pre-COVID (January 1, 2019 to December 31, 2019), stay-at-home (March 24, 2020 to May 18, 2020), during COVID (May 19, 2020 to March 28, 2021), and post-COVID (May 12, 2023 to August 31, 2023). Trend analysis was performed. Additionally, positivity rates during and post-COVID were compared to pre-COVID to determine any significant changes in drug positivity.
Results: Stimulant (amphetamines and cocaine), cannabinoid, and methadone positivity increased during the pandemic and cocaine, cannabinoid, and methadone positivity remains elevated. By contrast, benzodiazepine and opioid (opiates, fentanyl, oxycodone) positivity decreased and remains lower post-COVID compared to pre-COVID. Patients in the ED with blood alcohol over the legal limit decreased both during and post-COVID.
Conclusion: Our study showed that the COVID-19 pandemic significantly affected drug and alcohol positivity rates in patients presenting to the ED in greater Boston area. We encourage other institutions to perform similar analyses to help determine local drug use patterns and appropriate composition of UDS panels.

Because of high mutation rates, viruses constantly adapt to new environments. When propagated in cell lines, certain viruses acquire positively charged amino acids on their surface proteins, enabling them to utilize negatively charged heparan sulfate (HS) as an attachment receptor. In this study, we used enterovirus A71 (EV-A71) as model and demonstrated that unlike the parental MP4 variant, the cell-adapted strong HS-binder MP4-97R/167G does not require acidification for uncoating and releases its genome in the neutral or weakly acidic environment of early endosomes.

Background: Esophageal cancer is highly prevalent in China, predominantly represented by squamous cell carcinoma. This retrospective study sought to evaluate the diagnostic efficacy of four staining protocols in identifying early stage esophageal squamous cell carcinoma (ESCC).
Methods: A consecutive series of ninety biopsy samples of esophageal mucosa, collected retrospectively from March 2016 to December 2019, were obtained at Beijing Chao-Yang Hospital, a tertiary care facility in Beijing, China.

Introduction And Aims: Mitochondrial myopathies are rare genetic disorders for which no effective treatment exists. We previously showed that the pharmacological cyclophilin inhibitor cyclosporine A (CsA) extends the lifespan of fast-twitch skeletal muscle-specific mitochondrial transcription factor A knockout (Tfam KO) mice, lacking the ability to transcribe mitochondrial DNA and displaying lethal mitochondrial myopathy. Our present aim was to assess whether the positive effect of CsA was associated with improved in vivo mitochondrial energy production.

Background: Environmental contamination with eggs significantly impacts on opisthorchiasis transmission and disease control. This study assessed egg contamination in underwater sediments from canals and aimed to reduce transmission in egg-positive and downstream communities by controlling human opisthorchiasis in endemic area of Northeast Thailand.
Methods: Sediment samples from 14 sites in UdonThani municipality were determined for eggs.

The Hiroshima/Nagasaki (H/N) studies by the Radiation Effect Research Foundation have not shown increased leukaemia for acute doses below 200 milli-gray (mGy). By contrast the INWORKS study of leukaemia in workers stated: "This study provides strong evidence of positive associations between protracted low-dose radiation exposure and leukemia". The INWORKS study also claimed increased leukaemia, not including Chronic Lymphocytic Leukaemia, at cumulative occupational doses of less than 100 mGy.
