A new airtight sampling method for sulfur hexafluoride (SF) in groundwater.

In the past 20 years, sulfur hexafluoride (SF) has been considered a highly reliable tracer for assessing modern water (< 65 yrs old) in groundwater. However, modern-air contamination may introduce complications in interpreting data obtained using current sampling methods. A new airtight methodology isolates the sample from modern ambient air; thus, returning more reproducible and reliable results when compared to two traditional (air-sensitive and non-airtight) methods.

Bariatric surgery prior to pancreas transplantation: a retrospective matched case-control study.

Background: The clinical impact of bariatric surgery (BS) prior to pancreas transplantation (PTx) is unclear.

Setting: University of Minnesota Hospital, Minneapolis, MN.

Methods: This was a single center retrospective case-controlled study of all patients January 1, 1998 and May 1, 2024 with a history of BS prior to PTx.

Assessing the Need for Repeat EEG in Pediatric Patients with Idiopathic Generalized Epilepsy After Anti-Seizure Medication Withdrawal Following Seizure Freedom.

Background: Most patients with idiopathic generalized epilepsy have good seizure control on antiseizure medications. Although idiopathic generalized epilepsy subtypes such as juvenile absence epilepsy and juvenile myoclonic epilepsy have a high risk of relapse, childhood absence epilepsy may have seizure remission. After 2 years of seizure freedom in childhood absence epilepsy, typically antiseizure medications are discontinued, but follow-up protocols are unclear.

"Catching Chain" With Medicaid: The Impact of Medicaid Access on Opioid Overdose Mortality in Adults Released From State Detention.

Objective: To combat the heightened risk of opioid overdose death for individuals with criminal justice involvements, enhanced access to Medicaid remains paramount. This study examines the effect of a 2017 policy change in Pennsylvania that allowed for suspension, rather than termination, of Medicaid coverage while in prison on post-release opioid overdose mortality risk (OOMR) for adults released from Pennsylvania prisons.

Methods: This retrospective cohort study utilizes administrative records from the Pennsylvania Department of Corrections for adults ≥18 years diagnosed with opioid use disorder (OUD) released in either 2015 or 2018.

National trends in catheter angiography and cerebrovascular imaging in a group of privately insured patients in the US.

Background: Despite the increasing use of non-invasive imaging, DSA remains the gold standard for cerebrovascular imaging. However, trends in DSA utilization are poorly understood. The goal of this study was to describe DSA utilization in a large claims database in the US over a 13 year period.
