Social epidemiology of early adolescent nutrition.

Background: This study aimed to investigate associations between sociodemographic factors and dietary intake among a diverse population of early adolescents ages 10-13 years in the United States.

Methods: We examined data from the Adolescent Brain Cognitive Development (ABCD) Study in Year 2 (2018-2020, ages 10-13 years, N = 10,280). Multivariable linear regression models were conducted to estimate the adjusted associations between sociodemographic factors (age, sex, race and ethnicity, household income, parental education) and dietary intake of various food groups, measured by the Block Kids Food Screener.

Differential antigenic imprinting effects between influenza H1N1 hemagglutinin and neuraminidase in a mouse model.

Unlabelled: Understanding how immune history influences influenza immunity is essential for developing effective vaccines and therapeutic strategies. This study examines the antigenic imprinting of influenza hemagglutinin (HA) and neuraminidase (NA) using a mouse model with sequential infections by H1N1 virus strains exhibiting substantial antigenic differences in HA. In our pre-2009 influenza infection model, we observed that mice with more extensive infection histories produced higher levels of functional NA-inhibiting antibodies (NAI).

The clinico-pathological spectrum of plaque-type blue naevi and their potential for malignant transformation.

Aims: Plaque-type blue naevi are rare melanocytic tumours presenting as large, pigmented plaques at birth or during childhood. There is a risk for malignant transformation, but no larger comprehensive studies exist and the diagnosis is challenging, especially on limited biopsy material. The aim is to describe the clinicopathological features and behaviour of the disease more comprehensively.

Cutaneous Myoepithelial Neoplasms on Acral Sites Show Distinctive and Reproducible Histopathologic and Immunohistochemical Features.

Cutaneous myoepithelial neoplasms are a heterogenous group of neoplasms with mixed tumors typically affecting the head and myoepitheliomas showing a predilection for the extremities. Their malignant counterparts, myoepithelial carcinoma, and malignant mixed tumor are exceptionally rare in the skin, and the morphologic criteria for malignancy are only poorly defined. The aim of the present study was to characterize the clinicopathologic features of myoepithelial neoplasms presenting on acral skin.

Morphologically high-grade trichoblastic carcinoma: a clinicopathological study with long-term clinical follow-up.

Aims: Trichoblastic carcinomas (malignant trichoblastomas) are rare and poorly documented neoplasms characterised by malignant transformation of a pre-existing benign trichoblastoma, and are subdivided histologically into low-grade and high-grade tumours. Whereas morphologically low-grade trichoblastic carcinomas show indolent behaviour, morphologically high-grade trichoblastic carcinomas have been associated with a poor prognosis, but little is known about their true biological potential. The aim of this study was to better define the clinicopathological features and outcomes of morphologically high-grade trichoblastic carcinomas.

Acute dilated cardiomyopathy in the setting of catastrophic antiphospholipid syndrome and thrombotic microangiopathy: A case series and review.

Catastrophic antiphospholipid antibody syndrome (CAPS) is a rare form of antiphospholipid syndrome, an autoimmune condition characterized by vascular thromboses, pregnancy loss, and antiphospholipid (aPL) antibodies. Diagnosis of CAPS relies on thrombosis of at least three different organs systems over 1 week, histopathological evidence of small vessel occlusion, and high aPL antibody titers. In a subset of precipitating circumstances, activation or disruption of endothelial cells in the microvasculature may occur along with cardiomyopathy.

Phyllodes tumor with metastases to the skull managed with local excision: A case report.

The behavior of phyllodes tumors is unpredictable and can behave as benign fibroadenomas or malignant neoplasms mimicking the course of aggressive sarcomas, characterized by distant metastases and a high short-term mortality. The malignant forms are treated with surgery and adjuvant chemotherapy, but often with poor outcomes. We examine the first reported case of an aggressive osteosarcoma subtype of phyllodes tumor that recurred in the skull after total mastectomy and adjuvant chemotherapy.

Clear Cell Variant of Solid Pseudopapillary Neoplasm of the Pancreas: A Report of a Rare Variant and Review of the Literature.

The clear cell variant of solid pseudopapillary neoplasm (ccSPN) of the pancreas was first described in 2006. In this article, we report a case of this rare variant and review the few published reports. Both the current and previous reports show that ccSPN has several morphologic differences from conventional SPN, including clear vacuoles, fewer pseudopapillary formations, more solid/diffuse architecture, less hemorrhage, and fewer cholesterol clefts.

Predictive Value of FDG PET/CT to Detect Lymph Node Metastases in Cervical Cancer.

Purpose: The aim of this study was to determine the prognostic significance of PET/CT findings in women with cervical cancer and describe the normalization of lymph node SUVmax (nSUVmax).

Materials And Methods: A retrospective review was performed of 113 patients with cervical cancer who underwent a PET/CT before receiving definitive therapy. SUVmax measurements were normalized to the SUV of the pelvic blood pool.

Berunda Polypeptides: Multi-Headed Fusion Proteins Promote Subcutaneous Administration of Rapamycin to Breast Cancer .

Recombinant Elastin-Like Polypeptides (ELPs) serve as attractive scaffolds for nanoformulations because they can be charge-neutral, water soluble, high molecular weight, monodisperse, biodegradable, and decorated with functional proteins. We recently reported that fusion of the FK-506 binding protein 12 (FKBP) to an ELP nanoparticle (FSI) reduces rapamycin (Rapa) toxicity and enables intravenous (IV) therapy in both a xenograft breast cancer model and a murine autoimmune disease model. Rapa has poor solubility, which leads to variable oral bioavailability or drug precipitation following parenteral administration.

Rapamycin Eye Drops Suppress Lacrimal Gland Inflammation In a Murine Model of Sjögren's Syndrome.

Purpose: To evaluate the efficacy of topical rapamycin in treating autoimmune dacryoadenitis in a mouse model of Sjögren's syndrome.

Methods: We developed rapamycin in a poly(ethylene glycol)-distearoyl phosphatidylethanolamine (PEG-DSPE) micelle formulation to maintain solubility. Rapamycin or PEG-DSPE eye drops (vehicle) were administered in a well-established Sjögren's syndrome disease model, the male nonobese diabetic (NOD) mice, twice daily for 12 weeks starting at 8 weeks of age.

The possible role of propofol in drug-induced torsades de pointes: A real-world single-center analysis.

Background: Torsades de pointes (TdP) is a polymorphic ventricular tachycardia associated with QT prolongation. Propofol is a sedative-anesthetic with proarrhythmic effects on cardiac myocytes. We performed a retrospective study to determine the incidence of TdP following propofol exposure at Mayo Clinic (Rochester, MN) from 08/11/1998-11/20/2015.

MitraClip Therapy for Mitral Regurgitation: Secondary Mitral Regurgitation.

Therapy for mitral regurgitation (MR) has been synonymous with mitral valve surgery. Operative approaches for degenerative MR repair have been associated with excellent results, with durable long term outcomes. Surgery for functional MR has been less successful.

Phosphorylated ribosomal S6 (p-rpS6) as a post-treatment indicator of HER2 signalling targeted drug resistance.

Objective: To identify clinically relevant predictive biomarkers of trastuzumab resistance.

Material And Methods: MTT, FACS assays, immunoblotting and immunocytochemistry were used to phenotypically characterize drug responses of two cell models BT474R and SKBR3R. Student's t-test and Spearman's correlation were applied for statistic analysis.

Co-targeting estrogen receptor and HER2 pathways in breast cancer.

The estrogen steroid hormone receptor (ER) and human epithelial growth factor receptor 2 membrane tyrosine kinase growth factor receptor (HER2) are the mediators of two key pathways involved in breast carcinogenesis, invasive behavior and cell growth. Co-expression of these receptors results in specific biological features that are not fully understood, but include relative resistance to hormonal therapy and chemotherapy as well as better long-term outcome imparted by ER and worse outcome by HER2 expression. The ER and HER2 signaling pathways interact with each other as do many biological networks, and this creates opportunities for therapeutic co-targeting with agents that modulate these respective pathways.
