Lanthanide binding peptide surfactants at air-aqueous interfaces for interfacial separation of rare earth elements.

Rare earth elements (REEs) are critical materials to modern technologies. They are obtained by selective separation from mining feedstocks consisting of mixtures of their trivalent cation. We are developing an all-aqueous, bioinspired, interfacial separation using peptides as amphiphilic molecular extractants.

Interfacial rheology of lanthanide binding peptide surfactants at the air-water interface.

Peptide surfactants (PEPS) are studied to capture and retain rare earth elements (REEs) at air-water interfaces to enable REE separations. Peptide sequences, designed to selectively bind REEs, depend crucially on the position of ligands within their binding loop domain. These ligands form a coordination sphere that wraps and retains the cation.

How has our primary-care NHS-IAPT provision for PTSD adapted to the pandemic? A service evaluation of recovery pre-COVID-19 and peri-COVID-19.

Background: Mental health issues have been an ongoing major cause of global disability exacerbated by the COVID-19 pandemic. The unique challenges have been the high contagiousness of COVID-19 and atypical PTSD presentations e.g.

Pregnant Adolescents Admitted to an Inpatient Child and Adolescent Psychiatric Unit: An Eight-Year Review.

Study Objective: To assess patient outcomes and describe demographic data of pregnant adolescents admitted to an inpatient child and adolescent psychiatric unit, as well as to determine if it is safe to continue to admit pregnant adolescents to such a unit.

Design, Setting, And Participants: A descriptive retrospective chart review conducted at a free-standing pediatric hospital in northeast Ohio of all pregnant adolescents aged 13 to 17 years admitted to the inpatient child and adolescent psychiatric unit from July 2005 to April 2013.

Main Outcome Measures: Data collection included details on demographic, pregnancy status, and psychiatric diagnoses.

Assessment of adherence to guidelines for using progesterone to prevent recurrent preterm birth.

Objective: To assess if women with recurrent preterm birth had been offered, received, and adhered to progesterone supplementation guidelines and to ascertain reasons for failure to follow guidelines.

Methods: Charts of infants who were products of recurrent spontaneous preterm birth were reviewed at four neonatal intensive care units of Akron Children's Hospital. Mothers of identified infants were interviewed and charts abstracted to determine: if progesterone was offered; acceptance of progesterone; compliance with progesterone; and reasons why progesterone was declined.

Catheter ablation of supraventricular tachycardia without fluoroscopy during pregnancy.

Background: Although uncommon, supraventricular tachycardia is difficult to manage during pregnancy. Catheter ablation traditionally has been deferred owing to radiation exposure risks. Three-dimensional mapping is a new tool in cardiac electrophysiology, which is being utilized to eliminate fluoroscopy during catheter ablation.

The use of the Cervilenz device to aid in the diagnosis of premature labor.

Objective: A short cervix measured by transvaginal ultrasound has been correlated with increased risk for preterm delivery (PTD). Many patients presenting with a complaint of possible premature labor (PL); may not have access to cervical length (CL) screening by ultrasound. Cervilenz is an FDA cleared disposable device for obtaining vaginal CL measurements.

Successful pregnancy following both endometrial ablation and uterine artery embolization.

Objective: To present a description of the management of a pregnancy in a woman who had undergone endometrial ablation and uterine artery embolization for fibroids.

Design: Case report.

Setting: Division of Maternal Fetal Medicine within a tertiary community-based teaching hospital.

Totally anomalous pulmonary venous connection and complex congenital heart disease: prenatal echocardiographic diagnosis and prognosis.

Objective: The purpose of this study was to determine the accuracy of prenatal cardiac diagnosis, prognosis, and outcome of totally anomalous pulmonary venous connection (TAPVC) and to determine echocardiographic clues in the prenatal diagnosis of isolated TAPVC or TAPVC in association with other complex congenital heart disease (CHD).

Methods: We reviewed our 13-year experience of prenatal diagnosis of TAPVC. Thirteen fetuses were identified with the diagnoses of TAPVC.

On the brink, and over.

All in all, this has been a most successful and rewarding period of time for the Academy. Most rewarding of all, perhaps, is the increased recognition being given to the AAPA as a leader among membership organizations in the United States. This recognition underscores our continued commitment and growing capability to help our members and advance the PA profession in the interest of all patients.

A state-wide assessment of the obstetric, anesthesia, and operative team personnel who are available to manage the labors and deliveries and to treat the complications of women who attempt vaginal birth after cesarean delivery.

Objective: The purpose of this study was to determine on a state-wide basis the range of obstetric, anesthesia, and surgical team personnel who were available immediately to manage the labors and deliveries of women who attempted vaginal birth after cesarean delivery. Additionally, we tried to determine whether hospitals had stopped performing vaginal births after cesarean delivery or made changes in their policies regarding vaginal birth after cesarean delivery as a result of recent American College of Obstetricians and Gynecologists recommendations.

Study Design: Available immediately was defined as "being present in the hospital.
