Exposure to pediatric and adolescent gynecology (PAG) varies across residency programs in obstetrics and gynecology, family medicine, and pediatrics, as well as both adolescent medicine and PAG fellowship programs. Nevertheless, these programs are responsible for training residents and fellows and providing opportunities to fulfill PAG learning objectives. To that end, the North American Society for Pediatric and Adolescent Gynecology has taken a leadership role in PAG trainee education by creating and maintaining this Short Curriculum.

The importance of ion kinetic energy for interference removal in ICP-MS/MS.

The effect of ion kinetic energy on gas phase ion reactivity with ICP-MS/MS was investigated in order to explore tuning strategies for interference removal. The collision/reaction gases CO, NO and O were used to observe the ion product distribution for 48 elements using an Agilent tandem ICP-MS (ICP-MS/MS) as a function of reaction gas flow rate (pressure) and ion kinetic energy. The kinetic energy of the incident ion was varied by adjusting the octopole bias (V).

Pediatric and Adolescent Gynecology WebEd: A Brief Report of an Underutilized Online Learning Module.

Pediatric and adolescent gynecology (PAG) is a unique subspecialty for which accessible educational resources and clinical exposure have historically been limited; surveys show that trainees in both obstetrics and gynecology and pediatrics agree. In 2014, the North American Society for Pediatric and Adolescent Gynecology (NASPAG) introduced PAG WebEd, an original and interactive online case-based curriculum designed to bridge this learning gap. As of 2023, there are 35 published PAG WebEd clinical cases with key learning points that present, test, and discuss a variety of current PAG topics.

f-Block reactions of metal cations with carbon dioxide studied by inductively coupled plasma tandem mass spectrometry.

f-Block chemistry offers an opportunity to test current knowledge of chemical reactivity. The energy dependence of lanthanide cation (Ln = Ce, Pr, Nd-Eu) and actinide cation (An = Th, U-Am) oxidation reactions by CO, was observed by inductively coupled plasma tandem mass spectrometry. This reaction is commonly spin-unallowed because the neutral reactant (CO, Σ+g) and product (CO, Σ) require the metal and metal oxide cations to have the same spin state.

Deciphering local and regional hydroclimate resolves contradicting evidence on the Asian monsoon evolution.

The winter and summer monsoons in Southeast Asia are important but highly variable sources of rainfall. Current understanding of the winter monsoon is limited by conflicting proxy observations, resulting from the decoupling of regional atmospheric circulation patterns and local rainfall dynamics. These signals are difficult to decipher in paleoclimate reconstructions.
