Background And Aims: There are limited contemporary population-based data on epidemiology and outcomes in the United States. Our primary aim was to create a validated cohort of veterans with testing or treatment using Veterans Health Administration data.

Methods: Using Veterans Health Administration structured and unstructured data, we developed and validated 4 algorithms for infection (3 algorithms) and treatment status (1 algorithm).

Pulse Pressure as a Hemodynamic Parameter in Preeclampsia with Severe Features Accompanied by Fetal Growth Restriction.

: Modern management of preeclampsia can be optimized by tailoring the targeted treatment of hypertension to an individual's hemodynamic profile. Growing evidence suggests different phenotypes of preeclampsia, including those with a hyperdynamic profile and those complicated by uteroplacental insufficiency. Fetal growth restriction (FGR) is believed to be a result of uteroplacental insufficiency.

Dynamical forces drive organ morphology changes during embryonic development.

Organs and tissues must change shape in precise ways during embryonic development to execute their functions. Multiple mechanisms including biochemical signaling pathways and biophysical forces help drive these morphology changes, but it has been difficult to tease apart their contributions, especially from tissue-scale dynamic forces that are typically ignored. We use a combination of mathematical models and experiments to study a simple organ in the zebrafish embryo called Kupffer's vesicle.

Navigating Unique Diagnostic and Therapeutic Challenges in Premenstrual Dysphoric Disorder: A Case Report.

Premenstrual dysphoric disorder (PMDD) is a disabling form of premenstrual syndrome affecting females of reproductive age in the premenstrual period. The presentation may vary from severe mood lability to extreme attempts to end life, usually within a week before menstruation resulting in considerable stress, functional impairment, and interpersonal conflicts. We present an interesting case of a 19-year-old sexually active girl who presented with a polysubstance overdose owing to her cyclical episodes of severe mood symptoms including irritability and uncontrolled aggression.

Single-Cell RNA Sequencing Reveals Immunomodulatory Effects of Stem Cell Factor and Granulocyte Colony-Stimulating Factor Treatment in the Brains of Aged APP/PS1 Mice.

Alzheimer's disease (AD) leads to progressive neurodegeneration and dementia. AD primarily affects older adults with neuropathological changes including amyloid-beta (Aβ) deposition, neuroinflammation, and neurodegeneration. We have previously demonstrated that systemic treatment with combined stem cell factor (SCF) and granulocyte colony-stimulating factor (G-CSF) (SCF+G-CSF) reduces the Aβ load, increases Aβ uptake by activated microglia and macrophages, reduces neuroinflammation, and restores dendrites and synapses in the brains of aged APPswe/PS1dE9 (APP/PS1) mice.

Myelin basic protein mRNA levels affect myelin sheath dimensions, architecture, plasticity, and density of resident glial cells.

Myelin Basic Protein (MBP) is essential for both elaboration and maintenance of CNS myelin, and its reduced accumulation results in hypomyelination. How different Mbp mRNA levels affect myelin dimensions across the lifespan and how resident glial cells may respond to such changes are unknown. Here, to investigate these questions, we used enhancer-edited mouse lines that accumulate Mbp mRNA levels ranging from 8% to 160% of wild type.

Presentation and Outcome in S1P-RM and Natalizumab-Associated Progressive Multifocal Leukoencephalopathy: A Multicenter Cohort Study.

Background And Objectives: Progressive multifocal leukoencephalopathy (PML) is a severe neurologic disease resulting from JC virus reactivation in immunocompromised patients. Certain multiple sclerosis (MS) disease-modifying therapies (DMTs) are associated with PML risk, such as natalizumab and, more rarely, sphingosine-1-phosphate receptor modulators (S1P-RMs). Although natalizumab-associated PML is well documented, information on S1P-RM-associated PML is limited.

Hypoxia-Preconditioned BMSC-Derived Exosomes Induce Mitophagy via the BNIP3-ANAX2 Axis to Alleviate Intervertebral Disc Degeneration.

Intervertebral disc degeneration (IVDD) is a chronic degenerative disease involving the aging and loss of proliferative capacity of nucleus pulposus cells (NPCs), processes heavily dependent on mitochondrial dynamics and autophagic flux. This study finds that the absence of BCL2/adenovirus E1B 19 kDa interacting protein 3 (BNIP3) is associated with senescence-related NPC degeneration, disrupting mitochondrial quality control. Bone marrow mesenchymal stem cells (BMSCs) have multidirectional differentiation potential and produce extracellular vesicles containing cellular activators.

Povidone-iodine in vitro antiseptic efficacy as a function of exposure duration, concentration, preparation, and length of storage.

Purpose: Although 5% povidone-iodine (PVP-I) is frequently used as an ocular antiseptic agent, there is a lack of consensus regarding the effects of PVP-I concentration, storage after opening, and compounded preparation on PVP-I antisepsis. We performed a series of in-vitro experiments to determine the impact of these factors on PVP-I's inhibition of common causes of post-procedural eye infection.

Methods: Inhibition of microorganism growth was measured in-vitro as a function of active PVP-I exposure time.

Psychosis Associated With Hyperglycemia in a Female Patient With Type 1 Diabetes Mellitus: A Case Report.

This paper presents the case of a 22-year-old woman who was hospitalized multiple times with episodes of psychosis co-occurring with hyperglycemia. Her psychosis was characterized by auditory hallucinations, visual hallucinations, and disorganized speech and behavior. The patient has a prior medical history of type 1 diabetes mellitus (T1DM) and Graves' disease and was non-adherent to diabetic diet and medications.

Impact of glucagon-like peptide receptor agonists on endoscopy and its preoperative management: Guidelines, challenges, and future directions.

Glucagon-like peptide receptor agonists (GLP-1RA) are used to treat type 2 diabetes mellitus and, more recently, have garnered attention for their effectiveness in promoting weight loss. They have been associated with several gastrointestinal adverse effects, including nausea and vomiting. These side effects are presumed to be due to increased residual gastric contents.

Pediatric Formulas: An Update.

The recent shortage of pediatric formulas in the United States, caused by supply chain issues and contamination of formula products in 1 of the major manufacturing plants, led many families to seek an alternate formula for their children. The Food and Drug Administration (FDA) allowed import of infant formulas from selected European and non-European countries. The European infant formulas differ from those produced in the United States regarding the primary source of the formula, age category, mixing instructions, labeling requirements, and formula composition in terms of macronutrients and micronutrients.

Long-Term Prospective Outcomes of Intensity Modulated Radiotherapy for Locally Advanced Lung Cancer: A Secondary Analysis of a Randomized Clinical Trial.

Importance: The optimal radiotherapy technique for unresectable locally advanced non-small cell lung cancer (NSCLC) is controversial, so evaluating long-term prospective outcomes of intensity-modulated radiotherapy (IMRT) is important.

Objective: To compare long-term prospective outcomes of patients receiving IMRT and 3-dimensional conformal radiotherapy (3D-CRT) with concurrent carboplatin/paclitaxel for locally advanced NSCLC.

Design, Setting, And Participants: A secondary analysis of a prospective phase 3 randomized clinical trial NRG Oncology-RTOG 0617 assessed 483 patients receiving chemoradiotherapy (3D-CRT vs IMRT) for locally advanced NSCLC based on stratification.
