Inferring the CO2 Abundance in Comet 45P/Honda-Mrkos-Pajdušáková from [O i] Observations: Implications for the Source of Icy Grains in Cometary Comae

The Planetary Science Journal
The study of cometary composition is important for understanding our solar system's early evolutionary processes. Carbon dioxide (CO _2 ) is a common hypervolatile in comets that can drive activity but is more difficult to study than other hypervolatiles

Impact of early dexmedetomidine administration on short‐ and long‐term outcomes in critically traumatic brain injury patients: A retrospective study using the MIMIC‐IV database

Ibrain, EarlyView.
Our retrospective analysis of the Medical Information Mart for Intensive Care‐IV (MIMIC‐IV) database suggests that early use of dexmedetomidine is associated with lower short‐term (28‐day and in‐hospital) and long‐term (1‐year) mortality in patients with traumatic brain injury.

A JWST Study of the Remarkable Oort Cloud Comet C/2017 K2 (PanSTARRS)

The Planetary Science Journal
Comets, during their journeys into the inner solar system, deliver volatile gases, organics, and particulates into their comae that provide crucial information for assessing the physicochemical conditions in the outer disk from which they formed. Here we

Evaluating Brief Behavioural Activation for depression in adolescents with acquired brain injury using a single‐case experimental design

JCPP Advances, EarlyView.
Abstract Background Adolescents who have had an acquired brain injury (ABI) commonly experience depression. Brief Behavioural Activation (Brief BA) is a successful, values‐based intervention for managing depression in neurotypical adolescents. This study investigated the effectiveness of Brief BA, using a single‐case experimental design, with ...

Mortality after broad‐ versus narrow‐spectrum antibiotic treatment for patients with nursing and healthcare‐associated pneumonia: A nationwide retrospective cohort study

Journal of Hospital Medicine, EarlyView.
Abstract Background Nursing and healthcare‐associated pneumonia (NHCAP) is defined as pneumonia occurring in individuals with frequent healthcare contact, such as residents of care facilities or patients with impaired activities of daily living. The effectiveness of broad‐spectrum antibiotics in treating NHCAP remains unclear.

Things We Do for No Reason™: Withholding opioids among patients with acute pain and opioid use disorder

Journal of Hospital Medicine, EarlyView.
Abstract Hospitalists care for patients with acute pain who have an opioid use disorder and require pain management. Hospitalists may withhold opioids for acute pain due to a variety of reasons. However, adequate pain management in patients with opioid use disorder, including with opioids, is the standard of care. This piece explains how to best manage

Optical and Near-infrared Spectroscopy of the Outbursting Comet 12P/Pons-Brooks

The Astrophysical Journal
We present optical and near-infrared (NIR) observations of the outbursting, Halley-type comet 12P/Pons-Brooks (12P). Three NIR spectra were obtained during two outbursts in 2023 October and November, with the 3 m Infrared Telescope Facility and the ...
