Magnetic Performance and Anticorrosion Coating Stability of Thermally Demagnetized Nd-Fe-B Permanent Magnets for Reuse Applications.

Nd-Fe-B-type permanent magnets, containing approximately 30% critical rare-earth elements by weight, are essential components in renewable energy systems (e.g., wind turbines, hydroelectric generators) and electric vehicles.

Effects of Thermal Demagnetization in Air on the Microstructure and Organic Contamination of NdFeB Magnets.

Demagnetization is an essential step for the demounting and safe handling of end-of-life NdFeB. Thermal demagnetization in air is a straightforward option to demount adhesive-fixed or segmented magnets. However, this process is suspected to increase the uptake of contaminants like O, C and Zn from coatings and adhesives, potentially degrading the recyclate quality.

Processability and Separability of Commercial Anti-Corrosion Coatings Produced by In Situ Hydrogen-Processing of Magnetic Scrap (HPMS) Recycling of NdFeB.

The recycling of NdFeB magnets is necessary to ensure a reliable and ethical supply of rare earth elements as critical raw materials. This has been recognized internationally, prompting the implementation of large-scale legislative measured aimed at its resolution; for example, an ambitious recycling quote has been established in the Critical Raw Materials Act Successful recycling in sufficient quantities is challenged by product designs that do not allow the extraction and recycling of these high-performance permanent magnets without excessive effort and cost. This is particularly true for smaller motors using NdFeB magnets.

Prescription Opioid Dose Change Before Fatal Opioid-Detected Overdose.

Objective: The opioid overdose crisis continues within the United States, and the role of prescribed opioids and prescribing patterns in overdose deaths remains an important area of research. This study investigated patterns of prescription opioids dispensed in the 12 months before opioid-detected overdose death in Connecticut between May 8, 2016, and January 2, 2018, considering differences by demographic characteristics.

Method: The sample included decedents who had an opioid dispensed within 30 days preceding death.

Evidence of brain injury in fetuses of mothers with preterm labor with intact membranes and preterm premature rupture of membranes.

Background: Brain injury and poor neurodevelopment have been consistently reported in infants and adults born before term. These changes occur, at least in part, prenatally and are associated with intra-amniotic inflammation. The pattern of brain changes has been partially documented by magnetic resonance imaging but not by neurosonography along with amniotic fluid brain injury biomarkers.

Accessibility of Opioid Treatment Programs Based on Conventional vs Perceived Travel Time Measures.

Importance: Transportation barriers have long been associated with poorer health outcomes; this burden is especially acute for individuals with opioid use disorder (OUD), a chronic disease often associated with low socioeconomic status. Conventional travel time analyses may not fully account for experiential components of travel, thereby understating the true travel burden and overstating treatment accessibility to opioid treatment programs (OTPs).

Objective: To develop a metric of feels-like accessibility for those using public transit to access OTPs that accounts for the realistic travel burden on individuals with OUD.

Intra-amniotic infection and/or inflammation is associated with fetal cardiac concentric hypertrophy and diastolic dysfunction in preterm labor and preterm prelabor rupture of membranes.

Background: Preterm delivery is associated with cardiovascular remodeling and dysfunction in children and adults. However, it is unknown whether these effects are caused by the neonatal consequences of preterm birth or if these are already present in utero.

Objective: We evaluated fetal cardiac morphology and function in fetuses of mothers admitted for preterm labor or preterm prelabor rupture of membranes and the association of these changes with the presence of intra-amniotic infection and/or inflammation.

The effects of early time restricted eating plus daily caloric restriction compared to daily caloric restriction alone on continuous glucose levels.

Background: The median eating duration in the U.S. is 14.

Understanding chronic pain in Neurofibromatosis Type 1 using the Neurofibromatosis Pain Module (NFPM).

Neurofibromatosis Type 1 (NF1) is an autosomal dominant genetic disorder that can cause an individual significant chronic pain (CP). CP affects quality of life and daily functioning, yet there are limited effective treatments for CP within NF1. The current study describes the impact of CP using the Neurofibromatosis Pain Module (NFPM).

Receipt of opioid use disorder treatments prior to fatal overdoses and comparison to no treatment in Connecticut, 2016-17.

Objective: To determine the relative risk of death following exposure to treatments for OUD compared to no treatment.

Methods: In this retrospective cohort study we compiled and merged state agency data on accidental and undetermined opioid overdose deaths in 2017 and exposures to OUD treatment in the prior six months to determine incidence rates following exposure to different treatment modalities. These rates were compared to the estimated incidence among those exposed to no treatment to determine relative risk of death for each treatment exposure.

"It's starting to weigh on me": Exploring the Experiences and Support Needs of Harm Reduction Staff in Connecticut using the Social-Ecological Model.

Background: The experiences and perceived support needs of harm reduction workers in the USA have been understudied. While previous research has explored staff burnout and role-related stress, there is a research gap around potential supports for staff wellbeing and individual longevity in their roles. This is especially critical given the growing overdose crisis and the need for sustainable harm reduction programming.

Increased adherence to ACOG diagnostic guidelines for HDP following a workshop in Bolivia, a LMIC.

Objectives: Hypertensive disorders of pregnancy (HDP) exert a heavy mortality burden in low- to middle-income countries (LMIC). ACOG revised HDP diagnostic guidelines to improve identifying pregnancies at greatest risk but whether they are used in LMIC is unknown.

Study Design: We held a workshop to review ACOG guidelines in La Paz, Bolivia (BO) and then reviewed prenatal, labor and delivery records for all HDP diagnoses and twice as many controls at its three largest delivery sites during the year before and the nine months after a workshop (n = 1376 cases, 2851 controls during the two periods).

Anthropometric, dietary, and lifestyle factors and risk of advanced thyroid cancer: The NIH-AARP diet and health cohort study.

Background: Most patients diagnosed with thyroid cancer have low-risk disease, but some have a higher risk for persistent or recurrent disease and even death from thyroid cancer. Few studies have evaluated potential anthropometric, lifestyle, or dietary risk factors for advanced or aggressive types of thyroid cancer.

Methods: Using data from a large US cohort study, we examined associations for high-risk thyroid cancer (HRTC) and, separately, low-risk thyroid cancer (LRTC) in relation to anthropometric factors, diet, smoking, and alcohol consumption.

Xylazine in the drug supply: Emerging threats and lessons learned in areas with high levels of adulteration.

Background: Xylazine, a sedative analgesic drug approved as an animal tranquilizer but not for human use, has become an adulterant in the illicit opioid marketplace in North America. Recently declared an emerging health threat in the U.S.
