IUD Insertion Under Conscious Sedation: Patient Characteristics with Clinical Decisions.

Study Objective: Uptake of intrauterine devices (IUDs) in the adolescent population may be limited by anxiety and pain anticipated during the insertion procedure. Our institution offers conscious sedation for IUD insertion to mitigate this concern. The objective of this study was to identify characteristics and outcomes of teens choosing between two types of conscious sedation for insertion of a levonorgestrel IUD.

Selective Venous Sampling Prompting Unilateral Oophorectomy in an Adolescent With PCOS and Markedly Elevated Testosterone.

Background: For adolescents with suspected polycystic ovary syndrome (PCOS) and severely elevated testosterone concentrations, imaging is recommended to assess for neoplasm. Selective venous sampling (SVS) can be considered when imaging is nondiagnostic.

Case: An adolescent female treated for PCOS had a peak testosterone of 344 ng/dL (11.

Characterization of a novel inhibitor for the New Delhi metallo-β-lactamase-4: Implications for drug design and combating bacterial drug resistance.

The bacterial metallo-β-lactamases (MBLs) catalyze the inactivation of β-lactam antibiotics. Identifying novel pharmacophores remains crucial for the clinical development of additional MBL inhibitors. Previously, 1-hydroxypyridine-2(1H)-thione-6-carboxylic acid, hereafter referred to as 1,2-HPT-6-COOH, was reported as a low cytotoxic nanomolar β-lactamase inhibitor of Verona-integron-encoded metallo-β-lactamase 2, capable of rescuing β-lactam antibiotic activity.

Review of Recent Advances in Gas-Assisted Focused Ion Beam Time-of-Flight Secondary Ion Mass Spectrometry (FIB-TOF-SIMS).

Time-of-flight secondary ion mass spectrometry (TOF-SIMS) is a powerful chemical characterization technique allowing for the distribution of all material components (including light and heavy elements and molecules) to be analyzed in 3D with nanoscale resolution. Furthermore, the sample's surface can be probed over a wide analytical area range (usually between 1 µm and 10 µm) providing insights into local variations in sample composition, as well as giving a general overview of the sample's structure. Finally, as long as the sample's surface is flat and conductive, no additional sample preparation is needed prior to TOF-SIMS measurements.
