Despite the study of BCR::ABL1-positive and -negative myeloproliferative neoplasms (MPNs) providing seminal insights into cancer biology, tumor evolution and precision oncology over the past half century, significant challenges remain. MPNs are clonal hematopoietic stem cell-derived neoplasms with heterogenous clinical phenotypes and a clonal architecture which impacts the often-complex underlying genetics and microenvironment. The major driving molecular abnormalities have been well characterized, but debate on their role as disease-initiating molecular lesions continues.

Microplastic Migration and Transformation Pathways and Exposure Health Risks.

Environ Pollut

January 2025

Department of Pathology and Laboratory Medicine, The University of Kansas Medical Center, Kansas City, KS 66160, USA. Electronic address:

Plastics play a crucial role in modern life, but improper use and disposal have resulted in microplastics becoming widespread in the environment, raising significant concerns about both the environment and human health. Extensive research has explored the transformation mechanisms, bioaccumulation, ecological impacts, and health risks associated with microplastics. The present review first analyzes the migration, transformation, and degradation pathways of microplastics on a global scale, and then synthesizes current knowledge on the types, sources, and migration pathways of microplastics in soil, atmosphere, and aquatic environments, emphasizing transformation mechanisms like photo-aging and microbial degradation, and detailing their ecological and human health impacts.

Acute rhinosinusitis causes more than 30 million patients to seek health care per year in the United States. Respiratory tract infections, including bronchitis and sinusitis, account for 75% of outpatient antibiotic prescriptions in primary care. Sinusitis is a clinical diagnosis; the challenge lies in distinguishing between the symptoms of bacterial and viral sinusitis.

Models for Studying Ductal Carcinoma In Situ Progression.

Adv Exp Med Biol

January 2025

Department of Pathology and Laboratory Medicine, MS 3045, The University of Kansas Medical Center, Kansas City, KS, USA.

An estimated 55,720 new cases of ductal carcinoma in situ (DCIS) will be diagnosed in 2023 in the USA alone because of the increased use of screening mammography. The treatment goal in DCIS is early detection and treatment with the hope of preventing progression into invasive disease. Previous studies show progression into invasive cancer as well as reduction in mortality from treatment is not as high as previously thought.

Background: The gut-kidney axis is implicated in chronic kidney disease (CKD) morbidity. We describe how a panel of gut microbiome-derived toxins relates to kidney function and neurocognitive outcomes in children with CKD, consisting of indoleacetate, 3-indoxylsulfate, p-cresol glucuronide, p-cresol sulfate, and phenylacetylglutamine.

Methods: The Chronic Kidney Disease in Children (CKiD) cohort is a North American multicenter prospective cohort that enrolled children aged 6 months to 16 years with estimated glomerular filtration rate (eGFR) 30-89 ml/min/1.

The rapid emergence of CD20-targeting T-cell engagers in follicular lymphoma and large B-cell lymphoma has further expanded the treatment options for patients with relapsed or refractory disease. Herein, we review and discuss the standard-of-care products and indications for mosunetuzumab, epcoritamab, and glofitamab. We provide a detailed overview of the registrational clinical trials, as well as a review of ongoing trials and likely future indications.

Biomarker Panels for Discriminating Risk of CKD Progression in Children.

J Am Soc Nephrol

January 2025

Department of Pediatrics, Division of Nephrology, The Children's Hospital of Philadelphia, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, PA.

Background: We have previously studied biomarkers of tubular health (EGF), injury (KIM-1), dysfunction (alpha-1 microglobulin), and inflammation (TNFR-1, TNFR-2, MCP-1, YKL-40, suPAR), and demonstrated that plasma KIM-1, TNFR-1, TNFR-2 and urine KIM-1, EGF, MCP-1, urine alpha-1 microglobulin are each independently associated with CKD progression in children. In this study, we used bootstrapped survival trees to identify a combination of biomarkers to predict CKD progression in children.

Methods: The CKiD Cohort Study prospectively enrolled children 6 months to 16 years old with an eGFR of 30-90 ml/min/1.

Hospital Boarding Creates Critical Shortcomings in Disaster Preparedness.

Health Secur

January 2025

Michael Redlener, MD, FAEMS, is Medical Director, Mount Sinai West Department of Emergency Medicine; Co-Director, Center for Healthcare Readiness; and an Associate Professor, Department of Emergency Medicine; all at Icahn School of Medicine at Mount Sinai, New York City, NY.

Hospital patient boarding in emergency departments has reached unprecedented crisis levels over the past 4 years. Boarding and crowding has been demonstrated by prior literature to have adverse effects on patient care as well as increased associated costs. Importantly, the increase in hospital patient boarding has created critical shortcomings in disaster preparedness by limiting the capacity of emergency departments to respond to mass casualty incidents due to space and staffing constraints.

Bile acid sequestrant inhibits gluconeogenesis via inducing hepatic cysteine dioxygenase type 1 to reduce cysteine availability.

Am J Physiol Gastrointest Liver Physiol

January 2025

Harold Hamm Diabetes Center, Department of Biochemistry and Physiology, University of Oklahoma Health Sciences Center, Oklahoma City, OK 73104.

Bile acid sequestrants such as cholestyramine (ChTM) are gut-restricted bile acid binding resins that block intestine bile acid absorption and attenuate hepatic bile acid signaling. Bile acid sequestrants induce hepatic bile acid synthesis to promote cholesterol catabolism and are cholesterol lowering drugs. Bile acid sequestrants also reduce blood glucose in clinical trials and are approved drugs for treating hyperglycemia in type-2 diabetes.

Cell Host Microbe

January 2025

Department of Pathology, Microbiology, and Immunology, School of Veterinary Medicine, University of California, Davis, CA 95616, USA. Electronic address:

Evidence suggests that bats are important hosts of filoviruses, yet the specific species involved remain largely unidentified. Niemann-Pick C1 (NPC1) is an essential entry receptor, with amino acid variations influencing viral susceptibility and species-specific tropism. Herein, we conducted combinatorial binding studies with seven filovirus glycoproteins (GPs) and NPC1 orthologs from 81 bat species.

Heart failure (HF) is a life-threatening condition with severe incapacitating consequences. Many body organs and systems may be affected, which may also hinder the quality of life and finances at the individual and societal levels. Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have also emerged as potentially useful drugs in the HF domain and other medical fields, in addition to their glucose-lowering effect.

Patient-reported health status is an important assessment of patients with heart failure, but current approaches have substantial methodological and analytical limitations. Changes in the Kansas City Cardiomyopathy Questionnaire (KCCQ) are commonly presented as a measure of the effect of drugs and devices, most often as the between-group difference in population means or as the odds of showing threshold changes of 5, 10, 15, and 20 points. However, the presentation of mean differences is based on statistical assumptions that are routinely violated in most trials.
