Article Synopsis
  • This study reviewed opioid exposures in young children, specifically looking at data from America's Poison Centers® between 2016 and 2023, to assess the impact of fentanyl and medications for opioid use disorder.
  • Out of 34,632 reports, most exposures (96.7%) were unintentional, with a median age of exposure being 2 years. While overall reported exposures decreased by 57.5%, there was a concerning 300% increase in deaths and major effects.
  • The study emphasizes the importance of improving poisoning prevention strategies, as medications like buprenorphine and methadone showed a significant association with severe effects, alongside rising cases of fentanyl and heroin exposure.

Acute Kidney Injury (AKI) is characterized by an abrupt decline in kidney function and has been associated with excess risks of death, kidney disease progression, and cardiovascular events. The kidney has a high energetic demand with mitochondrial health being essential to renal function and damaged mitochondria has been reported across AKI subtypes. 5' adenosine monophosphate-activated protein kinase (AMPK) activation preserves cellular energetics through improvement of mitochondrial function and biogenesis when ATP levels are low such as under ischemia-induced AKI.

Article Synopsis
  • The study evaluated the use of fomepizole, an antidote for toxic alcohol poisoning, by analyzing data from the National Poison Data System over 12 years (2010-2021), noting its rising use especially after 2020.
  • Results showed that most cases (60%) involved actual toxic alcohol poisoning, with patient demographics indicating that toxic alcohol exposures were generally older and more likely to be male compared to non-toxic alcohol cases.
  • Interestingly, many patients receiving fomepizole did not have confirmed toxic alcohol poisoning, as reflected by fewer signs of critical health issues in these cases, which raises concerns about the accuracy of diagnosing toxic alcohol exposure with available testing methods.

Article Synopsis
  • There has been an increase in neonates born at 28 weeks gestation or earlier in the U.S., many requiring procedures like tracheostomy and laryngotracheal reconstruction (LTR), but no studies have assessed their post-surgical outcomes.
  • The study aimed to compare decannulation rates, time to decannulation, and complication rates in extremely premature infants undergoing LTR with those born preterm and at term.
  • Results showed that while extremely premature infants have similar decannulation success rates, they are more prone to complications after the surgery, and are more likely to need additional treatments like grafts and stents.

Article Synopsis
  • - The study investigates aspirin overdoses in children aged 5 and younger, aiming to link specific doses to medical outcomes, as existing guidelines for referral to emergency care lack sufficient pediatric data.
  • - A review of 26,488 cases showed that most aspirin exposures had no effects, while a small percentage resulted in minor to major effects or death, with lethal doses ranging significantly from 142.2 mg/kg to 284.4 mg/kg.
  • - The findings suggest that the current guideline recommending referral after 150 mg/kg of aspirin ingestion may need re-evaluation, given the observed outcomes and treatment responses in pediatric patients.

Patellofemoral stability is maintained through a complex network of static and dynamic soft-tissue stabilizers, the osseous structure of the patella and trochlea, and overall limb alignment. Thus, determining the risk of recurrent patellar instability must account for as many of these factors as possible in the clinical decision-making process. The tibial tubercle-trochlear groove distance is the most common parameter used for this evaluation but may be limited because of methodologic issues and because this distance is an absolute value.

Pramlintide is an equipotent amylin analogue that reduces food intake and body weight in obese subjects and has been clinically approved as an adjunctive therapy for the treatment of adult diabetic patients. However, due to its extremely short half-life in vivo, a regimen of multiple daily administrations is required for achieving clinical effectiveness. Herein is described the development of prototypical long-acting pramlintide bioconjugates, in which pramlintide's disulfide-linked macrocycle was replaced by a cyclic thioether motif.
