POCUS-first in acute diverticulitis: Quantifying cost savings, length-of-stay reduction, and radiation risk mitigation in the ED.

Background: Recent studies have validated the efficacy of point-of-care ultrasound (POCUS) as an alternative diagnostic imaging approach to computed tomography (CT) for patients with suspected acute diverticulitis. This study aimed to quantify the national impact of this approach in cost savings, ED length-of-stay (LOS), and radiation risk mitigation using a POCUS-first approach for acute diverticulitis in the emergency department (ED).

Methods: Using published data, we constructed a Monte Carlo simulation model to compare two POCUS-first strategies (nonselective and selective approaches) for evaluating patients with suspected acute diverticulitis in the ED.

Extended shortwave infrared absorbing antiaromatic fluorenium-indolizine chromophores.

Shortwave infrared (SWIR, 1000-1700 nm) and extended SWIR (ESWIR, 1700-2700 nm) absorbing materials are valuable for applications including fluorescence based biological imaging, photodetectors, and light emitting diodes. Currently, ESWIR absorbing materials are largely dominated by inorganic semiconductors which are often costly both in raw materials and manufacturing processes used to produce them. The development of ESWIR absorbing organic molecules is thus of interest due to the tunability, solution processability, and low cost of organic materials compared to their inorganic counterparts.

POCUS-first for nephrolithiasis: A Monte Carlo simulation illustrating cost savings, LOS reduction, and preventable radiation.

Objectives: Non-contrast computed tomography (NCCT) is the gold standard for nephrolithiasis evaluation in the emergency department (ED). However, Choosing Wisely guidelines recommend against ordering NCCT for patients with suspected nephrolithiasis who are <50 years old with a history of kidney stones. Our primary objective was to estimate the national annual cost savings from using a point-of-care ultrasound (POCUS)-first approach for patients with suspected nephrolithiasis meeting Choosing Wisely criteria.

Feasibility of an Exercise and CBT Intervention for Treatment of Depression: A Pilot Randomized Controlled Trial.

Depression (DEP) is prevalent and current treatments are ineffective for many people. This pilot study's purpose was to assess the feasibility, acceptability, and plausible efficacy of an 8-week intervention employing 30 min of prescribed moderate intensity exercise ("ActiveCBT") compared to 30 min of usual activities ("CalmCBT") immediately prior to weekly online CBT sessions. Ten adults with DSM-5-diagnosed current DEP were randomized to groups and completed: an intake assessment, eight weekly CBT sessions, final assessment, and 3-month follow-up.
