Perinatal attention-deficit/hyperactivity disorder diagnosis rates among commercially insured delivering women 2008-2020.

Objectives: Cognitive impairment and decreased executing functioning represent common symptoms of both ADHD and pregnancy. This study aimed to characterize temporal trends and racial/ethnic disparities in ADHD diagnosis during the perinatal period.

Methods: In this serial cross-sectional study, we used administrative claims to create a cohort of commercially insured women with a documented live birth between 2008 and 2020 and identified those with an ADHD diagnosis in the year before or after delivery.

Antidepressant Prescriptions Increased For Privately Insured People With Perinatal Mood And Anxiety Disorder, 2008-20.

We aimed to determine whether antidepressant prescriptions for perinatal mood and anxiety disorder (PMAD) increased after several professional organizations issued clinical recommendations in 2015 and 2016. This serial, cross-sectional, logistic regression analysis evaluated changes in antenatal and postpartum antidepressant prescriptions among commercially insured people who had a live-birth delivery as well as a PMAD diagnosis during the period 2008-20. For people with antenatal PMAD, the odds of an antenatal antidepressant prescription decreased 3 percent annually from 2008 to 2016 and increased by 32 percent in 2017, and the annual rate of change increased 5 percent for 2017-20 compared with 2008-16.

Diagnosed behavioral health conditions during the perinatal period among a commercially insured population by race/ethnicity, 2008-2020.

Objective: We sought to examine trends in diagnosed behavioral health (BH) conditions [mental health (MH) disorders or substance use disorders (SUD)] among pregnant and postpartum individuals between 2008-2020. We then explored the relationship between BH conditions and race/ethnicity, acknowledging race/ethnicity as a social construct that influences health disparities.

Methods: This study included delivering individuals, aged 15-44 years, and continuously enrolled in a single commercial health insurance plan for 1 year before and 1 year following delivery between 2008-2020.

Perinatal Mood And Anxiety Disorders Rose Among Privately Insured People, 2008-20.

Nationwide, perinatal mood and anxiety disorder (PMAD) diagnoses among privately insured people increased by 93.3 percent from 2008 to 2020, growing faster in 2015-20 than in 2008-14. Most states and demographic subgroups experienced increases, suggesting worsening morbidity in maternal mental health nationwide.

Trends in chronic pain conditions among delivering women with and without mood and anxiety disorders.

Objective: The co-existence of chronic pain conditions with anxiety and/or depression is common in the general population but poorly described during pregnancy. In this study, we sought to describe trends in chronic pain among a sample of delivering people and describe the co-existence of chronic pain with anxiety and/or depression among delivering people.

Methods: This cross-sectional study used data from Optum's de-identified Clinformatics® Data Mart Database between 2008 and 2021, for delivering persons with coverage by single employer-based health plan.

Clinical and Economic Outcomes in Patients With Metastatic Urothelial Carcinoma Receiving First-Line Systemic Treatment (the IMPACT UC I Study).

Background: The IMPACT UC I study assessed real-world treatment patterns, outcomes, healthcare resource utilization (HCRU), and costs in patients with metastatic urothelial carcinoma (mUC) receiving first-line (1L) systemic treatment after the FDA approval of 1L immune checkpoint inhibitor (ICI) monotherapy.

Patients And Methods: This retrospective study used 100% Medicare fee-for-service claims from 1/1/2015 to 6/30/2019 to identify patients aged ≥18 years diagnosed with UC with evidence of metastatic disease, continuously enrolled for 6 months before and after initial diagnosis. Patients were grouped by 1L treatment: cisplatin-containing chemotherapy, carboplatin-containing chemotherapy, ICI monotherapy, or nonplatinum-containing therapy.

Medicare characteristics, treatment, cost and survival in triple class exposed relapsed or refractory multiple myeloma.

This study describes real-world treatment patterns of Medicare beneficiaries with relapsed or refractory multiple myeloma (RRMM) who are triple class exposed (TCE). Retrospective analysis of Medicare fee for service claims to identify a cohort age >65 with RRMM + TCE, 1 January 2016 to 30 June 2019. Initiation of a new treatment regimen (TCE1), healthcare resource utilization, cost and mortality.

The Association between NICU Admission and Mental Health Diagnoses among Commercially Insured Postpartum Women in the US, 2010-2018.

Maternal mental health (MH) conditions represent a leading cause of preventable maternal death in the US. Neonatal Intensive Care Unit (NICU) hospitalization influences MH symptoms among postpartum women, but a paucity of research uses national samples to explore this relationship. Using national administrative data, we examined the rates of MH diagnoses of anxiety and/or depression among those with and without an infant admitted to a NICU between 2010 and 2018.

Burden of illness and outcomes in second-line large B-cell lymphoma treatment: real-world analysis of Medicare beneficiaries.

 To characterize elderly large B-cell lymphoma patients who progress to second-line treatment to identify potential unmet treatment needs. Retrospective USA cohort study, patients receiving second-line autologous stem cell transplant (SCT) preparative regimen ('ASCT-intended') versus those who did not; stratified further into those who received a stem cell transplant and those who did not. Primary outcomes were: healthcare resource utilization, costs and adverse events.

Fibroblast Activation Protein Cleaves and Inactivates Fibroblast Growth Factor 21.

FGF21 is a stress-induced hormone with potent anti-obesity, insulin-sensitizing, and hepatoprotective properties. Although proteolytic cleavage of recombinant human FGF21 in preclinical species has been observed previously, the regulation of endogenously produced FGF21 is not well understood. Here we identify fibroblast activation protein (FAP) as the enzyme that cleaves and inactivates human FGF21.

Regulation of corepressor alternative mRNA splicing by hormonal and metabolic signaling.

Alternative mRNA splicing diversifies the products encoded by the NCoR and SMRT corepressor loci. There is a programmed alteration in NCoR mRNA splicing during adipocyte differentiation from an NCoRω isoform, which contains three nuclear receptor interaction domains, to an NCoRδ isoform that contains two nuclear receptor interaction domains. This alternative mRNA splicing of NCoR has profound effects on adiposity and on diabetes in mouse models.

Alteration of NCoR corepressor splicing in mice causes increased body weight and hepatosteatosis without glucose intolerance.

Alternative mRNA splicing is an important means of diversifying function in higher eukaryotes. Notably, both NCoR and SMRT corepressors are subject to alternative mRNA splicing, yielding a series of distinct corepressor variants with highly divergent functions. Normal adipogenesis is associated with a switch in corepressor splicing from NCoRω to NCoRδ, which appears to help regulate this differentiation process.

Thyroid hormones, t3 and t4, in the brain.

Thyroid hormones (THs) are essential for fetal and post-natal nervous system development and also play an important role in the maintenance of adult brain function. Of the two major THs, T4 (3,5,3',5'-tetraiodo-l-thyronine) is classically viewed as an pro-hormone that must be converted to T3 (3,5,3'-tri-iodo-l-thyronine) via tissue-level deiodinases for biological activity. THs primarily mediate their effects by binding to thyroid hormone receptor (TR) isoforms, predominantly TRα1 and TRβ1, which are expressed in different tissues and exhibit distinctive roles in endocrinology.

The ability of thyroid hormone receptors to sense t4 as an agonist depends on receptor isoform and on cellular cofactors.

T4 (3,5,3',5'-tetraiodo-l-thyronine) is classically viewed as a prohormone that must be converted to the T3 (3,5,3'-triiodo-l-thyronine) form for biological activity. We first determined that the ability of reporter genes to respond to T4 and to T3 differed for the different thyroid hormone receptor (TR) isoforms, with TRα1 generally more responsive to T4 than was TRβ1. The response to T4 vs T3 also differed dramatically in different cell types in a manner that could not be attributed to differences in deiodinase activity or in hormone affinity, leading us to examine the role of TR coregulators in this phenomenon.

The two major isoforms of thyroid hormone receptor, TRα1 and TRβ1, preferentially partner with distinct panels of auxiliary proteins.

Thyroid hormone receptors (TRs) are expressed primarily as two major isoforms, TRα1 and TRβ1, which are expressed at different times in development and at different tissue abundances in the adult. The transcription properties and biological properties of TRα1 and TRβ1 can differ. We report here that although overlapping, TRα1 and TRβ1 recruit distinct panels of partner proteins that may account for their divergent biological functions, and which appear to explain their distinct target gene regulatory properties.

Transgenic soybean plants overexpressing O-acetylserine sulfhydrylase accumulate enhanced levels of cysteine and Bowman-Birk protease inhibitor in seeds.

Soybeans provide an excellent source of protein in animal feed. Soybean protein quality can be enhanced by increasing the concentration of sulfur-containing amino acids. Previous attempts to increase the concentration of sulfur-containing amino acids through the expression of heterologous proteins have met with limited success.

Threonine-insensitive homoserine dehydrogenase from soybean: genomic organization, kinetic mechanism, and in vivo activity.

Aspartate kinase (AK) and homoserine dehydrogenase (HSD) function as key regulatory enzymes at branch points in the aspartate amino acid pathway and are feedback-inhibited by threonine. In plants the biochemical features of AK and bifunctional AK-HSD enzymes have been characterized, but the molecular properties of the monofunctional HSD remain unexamined. To investigate the role of HSD, we have cloned the cDNA and gene encoding the monofunctional HSD (GmHSD) from soybean.

A redox-active isopropylmalate dehydrogenase functions in the biosynthesis of glucosinolates and leucine in Arabidopsis.

We report a detailed functional characterization of an Arabidopsis isopropylmalate dehydrogenase (AtIPMDH1) that is involved in both glucosinolate biosynthesis and leucine biosynthesis. AtIPMDH1 shares high homology with enzymes from bacteria and yeast that are known to function in leucine biosynthesis. In plants, AtIPMDH1 is co-expressed with nearly all the genes known to be involved in aliphatic glucosinolate biosynthesis.

Contributions of conserved serine and tyrosine residues to catalysis, ligand binding, and cofactor processing in the active site of tyrosine ammonia lyase.

Tyrosine ammonia lyase (TAL) catalyzes the conversion of L-tyrosine to p-coumaric acid using a 3,5-dihydro-5-methylidene-4H-imidazole-4-one (MIO) prosthetic group. In bacteria, TAL is used for production of the photoactive yellow protein chromophore and for caffeic acid biosynthesis in certain actinomycetes. Here we biochemically examine wild-type and mutant forms of TAL from Rhodobacter sphaeroides (RsTAL).
