From solubility to efficiency: Per- and polyfluoroalkyl substances (PFAS) regeneration from anion exchange resins.

This study investigated the regenerability of anion exchange resins for per- and polyfluoroalkyl substances (PFAS), focusing on the interaction between regenerant composition and resin characteristics. The influence of salt type and concentration on PFAS solubility revealed a general decline in perfluorohexane sulfonate (PFHxS) solubility with increased salt concentrations, most strongly with KCl followed by NaCl and NHCl. Mixed solubility results were observed for perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS).

Diagnostic yield of cystic fibrosis from a South Australian monocentric cohort: a retrospective study.

Objectives: To determine the diagnostic yield of cystic fibrosis (CF) using a two-tiered genetic testing approach. Although newborn screening includes CF, this typically only covers a selection of common genetic variants, and with over 2000 reported in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, we hypothesised that patients will be missed and present clinically later in life.

Design: A retrospective study over a 5-year period (January 2018-December 2022).

Synopsis of the 2023 US Department of Veterans Affairs and US Department of Defense Clinical Practice Guideline for the Management of Bipolar Disorder.

The US Department of Veterans Affairs (VA) and Department of Defense (DOD) Work Group revised the 2013 VA/DOD Clinical Practice Guideline (CPG) for the Management of Bipolar Disorder (BD). This paper reviews the 2023 CPG and its development process, including how recommendations were made for evidence-based treatment in BD. Subject experts and key stakeholders developed 20 key questions and reviewed the published literature after a systematic search using the PICOTS (population, intervention, comparator, outcomes, timing of outcomes measurement, and setting) method.

Risk of Hypertensive Disorders of Pregnancy in Patients With Cardiac Disease.

Background: Pregnant patients with cardiovascular disease (CVD) face increased risk of preeclampsia and preterm delivery, yet data is limited data regarding degree of risk and impact of hypertensive disorders of pregnancy (HDP) on gestational age at delivery.

Objectives: To examine HDP risk and impact on delivery timing in patients with CVD.

Methods: This retrospective cohort study included patients >18 years old who delivered between 10/1/2015 and 12/31/2020 using the Premier Healthcare Database.

Advancing forest carbon projections requires improved convergence between ecological and economic models.

Forests have the potential to contribute significantly to global climate policy efforts through enhanced carbon sequestration and storage in terrestrial systems and wood products. Projections models simulate changes future in forest carbon fluxes under different environmental, economic, and policy conditions and can inform landowners and policymakers on how to best utilize global forests for mitigating climate change. However, forest carbon modeling frameworks are often developed and applied in a highly disciplinary manner, e.
