Cxcl10 is required for survival during SARS-CoV-2 infection in mice.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological agent of the coronavirus disease 2019 (COVID-19) pandemic, remains endemic worldwide ∼5 years since the first documented case. Severe COVID-19 is widely considered to be caused by a dysregulated immune response to SARS-CoV-2 within the respiratory tract. Circulating levels of the chemokine CXCL10 are strongly positively associated with poor outcome; however, its precise role in pathogenesis and its suitability as a therapeutic target have remained undefined.

Combinations of substances contributing to death among overdose decedents in Maryland (2020-2021).

Background: In 2020, Maryland had the fourth-highest opioid overdose mortality rate in the USA. We describe substances identified in postmortem toxicology screening and designated as cause of death (COD) for overdose decedents in Maryland, including specific combinations of substances designated as COD.

Methods: We performed a retrospective analysis of N=5442 adult overdose decedents (ie, manner of death unintentional or undetermined) in Maryland between January 2020 and December 2021.

Recommencing anticoagulation treatment in surgically managed patients with intracerebral haemorrhage and mechanical heart valves: An Aotearoa-New Zealand analysis.

Purpose: Intracerebral haemorrhage (ICH) is an absolute contraindication for therapeutic oral anticoagulation therapy (OAT). Re-bleeding carries significant risk of morbidity and mortality. Patients with prosthetic heart valves are at higher risk of thromboembolic complications when OAT is withheld.

Postmortem distribution of mitragynine and 7-hydroxymitragynine in 51 cases.

The prevalence of mitragynine (kratom) in forensic toxicology casework has steadily increased over time. Readily available and currently legal, mitragynine is widely used for its stimulant and, depending on concentration, sedative effects. Our laboratory analyzed various fluid and tissue specimens from 51 postmortem cases to investigate the distribution of mitragynine and its active metabolite 7-hydroxymitragynine.

Nutritional optimization of fecal microbiota transplantation in humans: a scoping review.

Diet constitutes a major source of nutrient flow to the gut microbes. As such, it can be used to help shape the gut microbiome. Fecal microbiota transplantation (FMT) is an increasingly promising therapy in disease states beyond recurrent infection, but diet is largely overlooked for its potential to help optimize this therapy.
