Purpose: To assess the performance of full dose (FD) positron emission tomography (PET) image synthesis in both image and projection space from low-dose (LD) PET images/sinograms without sacrificing diagnostic quality using deep learning techniques. Methods: Clinical brain PET/CT studies of 140 patients were retrospectively employed for LD to FD PET conversion. 5% of the events were randomly selected from the FD list-mode PET data to simulate a realistic LD acquisition. A modified 3D U-Net model was implemented to predict FD sinograms in the projection-space (PSS) and FD images in image-space (PIS) from their corresponding LD sinograms/images, respectively. The quality of the predicted PET images was assessed by two nuclear medicine specialists using a five-point grading scheme. Quantitative analysis using established metrics including the peak signal-to-noise ratio (PSNR), structural similarity index metric (SSIM), region-wise standardized uptake value (SUV) bias, as well as first-, second- and high-order texture radiomic features in 83 brain regions for the test and evaluation dataset was also performed. Results: All PSS images were scored 4 or higher (good to excellent) by the nuclear medicine specialists. PSNR and SSIM values of 0.96 ± 0.03, 0.97 ± 0.02 and 31.70 ± 0.75, 37.30 ± 0.71 were obtained for PIS and PSS, respectively. The average SUV bias calculated over all brain regions was 0.24 ± 0.96% and 1.05 ± 1.44% for PSS and PIS, respectively. The Bland-Altman plots reported the lowest SUV bias (0.02) and variance (95% CI: -0.92, +0.84) for PSS compared with the reference FD images. The relative error of the homogeneity radiomic feature belonging to the Grey Level Co-occurrence Matrix category was -1.07 ± 1.77 and 0.28 ± 1.4 for PIS and PSS, respectively Conclusion: The qualitative assessment and quantitative analysis demonstrated that the FD PET prediction in projection space led to superior performance, resulting in higher image quality and lower SUV bias and variance compared to FD PET prediction in the image domain.

The University of Iowa recently completed a 4-y expedition into the uncharted waters of the Food and Drug Administration (FDA) new-drug application (NDA) process that ultimately resulted in approval of ⁶⁸Ga-DOTATOC in August 2019. The journey was enlightening, revealing a highly structured, arcane, but rigorous regulatory approval process. The FDA proved to be an efficient, reasonable, and communicative regulatory body that achieved balance between support of the initiative and its mission-bound, process-bound duty to ensure that the application met the expected safety and efficacy standards of the agency. With several clinically valuable PET radiopharmaceuticals without intellectual property residing in regulatory limbo, without industry champions to bring them to marketing approval, there may be justification for a more concerted effort from the molecular imaging community into generating better understanding, support, and perhaps even infrastructure for the academic NDA. As a first step, this article briefly describes the start-to-finish story for ⁶⁸Ga-DOTATOC, including a description of the clinical trials, a broad overview of the structured content of the NDA document, and the distilled experiences associated with the ⁶⁸Ga-DOTATOC NDA process. It is anticipated that with sustained free sharing of information relating to the FDA drug registration process, it will prove less daunting and more efficient in future academically sponsored NDA filings for PET imaging agents.

High school graduation is a landmark event for students. It also plays an important role in the state accountability systems designed to ensure that schools provide all students a high-quality education. Yet relying on a school's four-year graduation rate for federal accountability purposes can have unintended consequences for English Learners, who may need extra time to graduate.

These fact sheets provide a sketch of key characteristics of the foreign-born and English Learner (EL) populations in select states. The fact sheets look at the demographics of these states, discuss EL student outcomes as measured by standardized tests, and conclude with an overview of state accountability mechanisms that affect ELs under relevant provisions of the Every Student Succeeds Act and predecessor No Child Left Behind Act.

As the share of U.S. children under age 8 who are Dual Language Learners (DLLs) increases, state policies have an important role to play in ensuring all young learners are able to get their education off to a good start. These fact sheets compare key characteristics of DLLs and their peers nationwide and in 30 states, and identify state policies that support equitable access to high-quality early childhood education and care programs.

States are in the midst of designing new policies to hold schools accountable for the education of English Learner (EL) students, as mandated by the federal Every Student Succeeds Act (ESSA). This series of fact sheets sketches the characteristics of immigrant and EL students in 25 states, the gaps between their educational outcomes and those of their peers, and the accountability policies each state is developing.

While low-skilled workers generally have limited opportunities to legally migrate to the European Union, seasonal migration forms an important exception. This MPI Europe-SVR webinar explores lessons from Europe on managing seasonal worker programs that are responsive to labor market needs but also prioritize the well-being of seasonal workers and interests of receiving countries. 

Enactment of the Every Student Succeeds Act (ESSA) in 2015 introduced opportunities to use federal funds to strengthen the early childhood education and care (ECEC) workforce as a means of better meeting the needs of the growing and increasingly diverse young child population.

As maritime arrivals climbed in 2015, EU policymakers struggled to mount a coordinated response. A range of ad hoc crisis-response tools emerged, but many officials worry that if another migration emergency were to hit Europe, the European Union may still be unprepared. This report traces the evolution of the EU response to the 2015–16 crisis and lays out recommendations to lock in progress and shore up weaknesses.

As European asylum systems are tested again by the COVID-19 pandemic, which has injected the need for social distancing during processing and in reception centers, it appears lessons learned during the 2015-16 migration and refugee crisis may be fading. Chief among them: A number of Member States have phased out their buffer capacity. This MPI Europe commentary explores the diametrically different approaches taken to asylum during the pandemic.

In an era of stepped-up immigration enforcement, speakers at this event present their research on the impact of enforcement policies on children from immigrant families and U.S. public schools. 

Marking the release of an MPI brief, experts on this webinar examine the key features of English Learner (EL) instructional models and discuss state- and district-level approaches to supporting schools in implementing effective EL program models, with a particular focus on what is being done in New York and Madison Wisconsin. 

Dual Language Learners (DLLs) are a growing segment of the Minnesota young child population, and a particularly "superdiverse" one with myriad origins, cultures, and languages—a new reality other states and communities will face. Drawing on interviews with policymakers and service providers, as well as analysis of census data, this report examines what this incredible diversity means for the state’s early childhood policies and programs.

To successfully integrate, immigrants and refugees need a variety of skills and knowledge—from English proficiency to understanding how school systems and local services work. Yet the adult education programs in place to support them have narrowed in scope. This policy brief proposes a new instructional model, English Plus Integration, to help states more comprehensively meet the diverse needs of their adult immigrant learners.

WASHINGTON – Four years since the Every Student Succeeds Act (ESSA) was signed into law, all 50 states, the District of Columbia and Puerto Rico have developed accountability plans that include blueprints for serving English Learners (ELs), as well as measuring these students’ progress and being accountable for their outcomes. This marked a significant development, as EL performance was previously not well integrated with factors that determined whether a school was performing well or poorly.

WASHINGTON – The federal Every Student Succeeds Act of 2015 (ESSA) requires states to publicly report annual performance and graduation rates for students in a range of areas, breaking out results for subgroups with unique characteristics, including English Learners (ELs). The objective is to help schools identify and close achievement gaps experienced by historically underserved groups of students.

This MPI webinar marks the release of a policy brief that explores program and policy opportunities to improve home visiting services for immigrant and DLL families currently underparticipating in these programs due to a lack of culturally and linguistically responsive programming and other barriers

Experts share how states have approached Every Student Succeeds Act (ESSA) implementation, and areas where the law and state efforts to support English Learners can be improved.

All 50 states, the District of Columbia, and Puerto Rico have developed blueprints to meet their commitments under the Every Student Succeeds Act—including requirements that aim to raise the profile of English Learners (EL) in state accountability systems. This report breaks these plans down, comparing the significant diversity of approaches taken on everything from EL identification to tracking academic achievement.

States publish a wealth of data about their English Learner students’ academic achievement and other outcomes such as graduation rates. But the answer to the question “Who is an EL?” is not always the same. This brief explains how the EL subgroup varies across states and types of data, and why it is important to understand these differences when making decisions about how ELs and schools are faring.

OBJECTIVE

To construct and internally validate prediction models to estimate the risk of long-term end-organ complications and mortality in patients with type 2 diabetes and obesity that can be used to inform treatment decisions for patients and practitioners who are considering metabolic surgery.

Marking a policy brief's release, this webinar explores the promise of home visiting services that support new parents alongside their infants and toddlers, plus strategies for improving how these programs work with immigrant and linguistically diverse families.

Experts share how states have approached Every Student Succeeds Act (ESSA) implementation, areas where the law and state efforts to support English Learners can be improved, and findings from the compendium, The Patchy Landscape of State English Learner Policies under ESSA. 

As the European Union prepares to review the implementation of its Seasonal Workers Directive, as well as countries such as the United Kingdom continue to explore new approaches to selecting seasonal workers, this webinar features findings from a policy brief on the topic. 

This podcast features a discussion between MPI's Margie McHugh and Julie Sugarman about how to understand the varying composition of states' English Learner (EL) subgroup under ESSA, and why understanding these technical differences matters when making decisions about how ELs and schools are faring. They also talk about different groups of ELs: newcomers, students with interrupted formal education, and long-term ELs, and data collection around these different cohorts.

Home visiting programs for young families are growing in popularity across the United States, and have demonstrated their effectiveness in supporting maternal health and child well-being. At the same time, more infants and toddlers are growing up in immigrant families and households where a language other than English is spoken. Why then are these children under-represented in these programs? This brief explores common barriers, ways to address them, and why it is important to do so.
