Metabolomic Response to Non-Steroidal Anti-Inflammatory Drugs.

Non-steroidal anti-inflammatory drugs (NSAIDs) are popular choices for the mitigation of pain and inflammation; however, they are accompanied by side effects in the gastrointestinal and cardiovascular systems. We compared the effects of naproxen, a traditional NSAID, and celecoxib, a cyclooxygenase -2 (Cox-2) inhibitor, in humans. Our findings showed a decrease in tryptophan and kynurenine levels in plasma of volunteers treated with naproxen.

Considerations for the Safe Operation of Schools During the Coronavirus Pandemic.

During the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, providing safe in-person schooling has been a dynamic process balancing evolving community disease burden, scientific information, and local regulatory requirements with the mandate for education. Considerations include the health risks of SARS-CoV-2 infection and its post-acute sequelae, the impact of remote learning or periods of quarantine on education and well-being of children, and the contribution of schools to viral circulation in the community. The risk for infections that may occur within schools is related to the incidence of SARS-CoV-2 infections within the local community.

Time-Dependent Hypotensive Effect of Aspirin in Mice.

Objective- Evening but not morning administration of low-dose aspirin has been reported to lower blood pressure in hypertensive patients. The present study was designed to determine whether this phenomenon could be replicated in mice, and if so, whether a time-dependent effect of aspirin on blood pressure was because of alteration of circadian clock function. Approach and Results- We recapitulated the protective effect of aspirin (50 μg/d for 7 days) at zeitgeber time 0 (active-to-rest transit), but not at zeitgeber time 12, on a high-salt diet-induced increase of blood pressure.

Integrative genomics identifies 7p11.2 as a novel locus for fever and clinical stress response in humans.

Fever predicts clinical outcomes in sepsis, trauma and during cardiovascular stress, yet the genetic determinants are poorly understood. We used an integrative genomics approach to identify novel genomic determinants of the febrile response to experimental endotoxemia. We highlight multiple integrated lines of evidence establishing the clinical relevance of this novel fever locus.

Is uric acid protective or deleterious in acute ischemic stroke? A prospective cohort study.

Contrasting observations have been made between serum urate and ischemic stroke outcomes in studies involving Caucasian populations. To assess the hypothesis that urate is associated with stroke outcomes, a prospective follow-up study was performed in a cohort of Asian patients with ischemic stroke. Patients diagnosed with transient ischemic attack, first or recurrent ischemic stroke were included in this study.
