Patient-reported outcome improvements following scalp hair regrowth among patients with Alopecia Areata: analysis of the ALLEGRO-2b/3 trial.

Alopecia areata (AA), an autoimmune disorder characterized by non-scarring hair loss, is detrimental to the psychological health and quality of life of people living with AA. Clinically meaningful hair regrowth is possible, but the relationship with downstream patient-reported outcomes (PROs) is complex. This post hoc analysis of ALLEGRO-2b/3 (NCT03732807) longitudinal data from Weeks 24-48 compared improvements in PROs between patients who achieved (responders) or did not achieve (non-responders) clinically meaningful scalp hair regrowth.

Guanine-based spin valve with spin rectification effect for an artificial memory element.

Non-volatile electronic memory elements are very attractive for applications, not only for information storage but also in logic circuits, sensing devices and neuromorphic computing. Here, a ferroelectric film of guanine nucleobase is used in a resistive memory junction sandwiched between two different ferromagnetic films of Co and CoCr alloys. The magnetic films have an in-plane easy axis of magnetization and different coercive fields whereas the guanine film ensures a very long spin transport length, at 100 K.

Telerehabilitation of subjects with neurodevelopmental disorders during confinement due to COVID-19.

Introduction: Social distancing measures due to the COVID-19 pandemic prevented many children with neurodevelopmental disorders from accessing face-to-face treatments. Telerehabilitation grew at this time as an alternative therapeutic tool. In this study we analysed remote cognitive rehabilitation in neurodevelopmental disorders.

A Second Trimester Prediction Algorithm for Early-Onset Hypertensive Disorders of Pregnancy Occurrence and Severity Based on Soluble fms-like Tyrosine Kinase 1 (sFlt-1)/Placental Growth Factor (PlGF) Ratio and Uterine Doppler Ultrasound in Women at Risk.

Hypertensive disorders of pregnancy (HDPs) represent a significant source of severe maternal and fetal morbidity. Screening strategies relying on traditional medical history and clinical risk factors have traditionally shown relatively modest performance, mainly in the prediction of preeclampsia, displaying a sensitivity of 37% for the early-onset form and 29% for the late-onset form. The development of more accurate predictive and diagnostic models of preeclampsia in the early stages of pregnancy represents a matter of high priority.

A post hoc analysis of Projected Retained Ability Scores (PRAS) for the longitudinal assessment of cognitive functioning in patients with neuronopathic mucopolysaccharidosis II receiving intrathecal idursulfase-IT.

Background: Norm-based scores used to assess cognitive ability have clinical value when describing functioning of patients with neuronopathic disorders compared with unaffected, same-age peers. However, they have limitations when used to assess change in cognitive ability between two timepoints, especially in children with severe cognitive decline. Calculation of Projected Retained Ability Scores (PRAS) is a novel method developed to characterize absolute change in norm-based ability test scores.

The Current Role of the sFlt-1/PlGF Ratio and the Uterine-Umbilical-Cerebral Doppler Ultrasound in Predicting and Monitoring Hypertensive Disorders of Pregnancy: An Update with a Review of the Literature.

Regarding the hypertensive disorders of pregnancy, pre-eclampsia (PE) remains one of the leading causes of severe and life-threatening maternal and fetal complications. Screening of early-onset PE (<34 weeks of pregnancy), as well as late-onset PE (≥34 weeks), shows poor performance if based solely on clinical features. In recent years, biochemical markers from maternal blood-the pro-angiogenic protein placental growth factor (PlGF) and the antiangiogenic protein soluble FMS-like tyrosine kinase 1 (sFlt-1)-and Doppler velocimetry indices-primarily the mean uterine pulsatility index (PI), but also the uterine resistivity index (RI), the uterine systolic/diastolic ratio (S/D), uterine and umbilical peak systolic velocity (PSV), end-diastolic velocity (EDV), and uterine notching-have all shown improved screening performance.

Surface charge dynamics on air-exposed ferroelectric Pb(Zr,Ti)O(001) thin films.

Probing of the free surface ferroelectric properties of thin polar films can be achieved either by estimating the band bending variance under the top-most layer or by studying the extent of the extrinsic charge accumulated outside the surface. Photoemitted or incoming low-energy electrons can be used to characterize locally both properties in a spectromicroscopic approach. Thin ferroelectric lead zirco-titanate (PZT) is investigated by combining low energy/mirror electron microscopy (LEEM/MEM) with photoemission electron microscopy (PEEM) and high-resolution photoelectron spectroscopy (XPS).

Experimental Band Structure of Pb(Zr,Ti)O : Mechanism of Ferroelectric Stabilization.

Pb(Zr,Ti)O (PZT) is the most common ferroelectric (FE) material widely used in solid-state technology. Despite intense studies of PZT over decades, its intrinsic band structure, electron energy depending on 3D momentum k, is still unknown. Here, Pb(Zr Ti )O using soft-X-ray angle-resolved photoelectron spectroscopy (ARPES) is explored.

Quality of life outcomes in two phase 3 trials of setmelanotide in patients with obesity due to LEPR or POMC deficiency.

Introduction: Individuals with proopiomelanocortin (POMC) or leptin receptor (LEPR) deficiency are young and experience severe obesity, hyperphagia, and comorbidities, which can impair quality of life (QOL).

Methods: Two pivotal Phase 3 trials explored the effect of setmelanotide on body weight and hunger in individuals with obesity due to POMC (NCT02896192) or LEPR (NCT03287960) deficiency. QOL and depression were investigated in parallel using the disease-specific, age-appropriate Impact of Weight on Quality of Life-Lite (IWQOL-Lite), Pediatric Quality of Life Inventory (PedsQL), and Patient Health Questionnaire-9 (PHQ-9).

Controlling polarization direction in epitaxial Pb(ZrTi)O films through Nb (n-type) and Fe (p-type) doping.

Fe (acceptor) and Nb (donor) doped epitaxial Pb(ZrTi)O (PZT) films were grown on single crystal SrTiO substrates and their electric properties were compared to those of un-doped PZT layers deposited in similar conditions. All the films were grown from targets produced from high purity precursor oxides and the doping was in the limit of 1% atomic in both cases. The remnant polarization, the coercive field and the potential barriers at electrode interfaces are different, with lowest values for Fe doping and highest values for Nb doping, with un-doped PZT in between.

Influence of Thickness on the Magnetic and Magnetotransport Properties of Epitaxial LaSrMnO Films Deposited on STO (0 0 1).

Epitaxial LaSrMnO films with different thicknesses (9-90 nm) were deposited on SrTiO (0 0 1) substrates by pulsed laser deposition. The films have been investigated with respect to morpho-structural, magnetic, and magneto-transport properties, which have been proven to be thickness dependent. Magnetic contributions with different switching mechanisms were evidenced, depending on the perovskite film thickness.

Homogeneous versus Inhomogeneous Polarization Switching in PZT Thin Films: Impact of the Structural Quality and Correlation to the Negative Capacitance Effect.

Polarization switching in ferroelectric films is exploited in many applications, such as non-volatile memories and negative capacitance field affect transistors. This can be inhomogeneous or homogeneous, depending on if ferroelectric domains are forming or not during the switching process. The relation between the polarization switching, the structural quality of the films and the negative capacitance was not studied in depth.

Understanding Barriers in the Pathway to Diagnosis of Ankylosing Spondylitis: Results From a US Survey of 1690 Physicians From 10 Specialties.

Objective: Early diagnosis of ankylosing spondylitis (AS) remains challenging because of the high prevalence of chronic back pain in patients initially treated by nonrheumatology health care providers (HCPs). We assessed the patient pathway to rheumatology referral, including HCP recognition of inflammatory back pain (IBP) and other features suggestive of AS, diagnostic workup, treatment, and referral to a specialist with the goal of identifying barriers to patient referral to a rheumatologist.

Methods: US HCPs from 10 specialties were invited to participate in a cross-sectional web-based survey on clinical characteristics and diagnostic measures leading to IBP suspicion and the subsequent referral process.

An unusual presentation of a retroperitoneal tumor - CEUS characterization and outcome.

We present a case of a 51-year-old woman referred to our department for unspecific abdominal pain. Two hypoechoic focal lesions in the retroperitoneal space and one hypoechoic mass superficially located in the mesogastrium were found at ultrasound (US) examination. All three masses were characterized as malignant by using contrast enhanced ultrasound (CEUS), due to the rapid hyperenhancement pattern followed by rapid wash-out.
