Inferring school district learning modalities during the COVID-19 pandemic with a hidden Markov model.

During the COVID-19 pandemic, many public schools across the United States shifted from fully in-person learning to alternative learning modalities such as hybrid and fully remote learning. In this study, data from 14,688 unique school districts from August 2020 to June 2021 were collected to track changes in the proportion of schools offering fully in-person, hybrid and fully remote learning over time. These data were provided by Burbio, MCH Strategic Data, the American Enterprise Institute's Return to Learn Tracker and individual state dashboards.

Cochlear hair cell innervation is dependent on a modulatory function of Semaphorin-3A.

Background: Proper connectivity between type I spiral ganglion neurons (SGNs) and inner hair cells (IHCs) in the cochlea is necessary for conveying sound information to the brain in mammals. Previous studies have shown that type I SGNs are heterogeneous in form, function and synaptic location on IHCs, but factors controlling their patterns of connectivity are not well understood.

Results: During development, cochlear supporting cells and SGNs express Semaphorin-3A (SEMA3A), a known axon guidance factor.

Sinonasal Undifferentiated Carcinoma with Failed Response to Induction Chemotherapy.

Sinonasal undifferentiated carcinoma (SNUC) is a rapidly growing malignancy with a propensity for extensive local invasion. Multimodal therapy, including surgery, radiotherapy, and chemotherapy, is the standard approach to treatment, but the optimal sequence and combination of these modalities are uncertain. Induction chemotherapy is being increasingly utilized based on recent reports that show better outcomes for patients who respond to chemotherapy and the ability to determine further course of treatment.

Sinonasal Glomangiopericytoma with Prolonged Postsurgical Follow-Up.

Sinonasal glomangiopericytoma is a rare vascular tumor of the respiratory epithelium. Treatment consists mainly of surgical resection, though there is no consensus regarding the use of adjuvant therapies or preoperative endovascular embolization. The postsurgical prognosis is favorable, though there is a high risk of delayed recurrence.

Predictive Value of a Genomic Classifier in Indeterminate Thyroid Nodules Based on Nodule Size.

Importance: Genomic classifiers were developed to better guide clinicians in the treatment of indeterminate thyroid nodules (ITNs). To our knowledge, whether there is variation in the diagnostic accuracy of these tests depending on ITN size has not been previously studied.

Objective: To analyze the diagnostic performance of a genomic classifier in relation to ITN size.

Solid Pseudopapillary Tumor of the Pancreas in a 25-Year-Old Female: A Rare Entity of Pancreatic Tumors.

Solid pseudopapillary neoplasms (SPMs) of the pancreas are extremely rare tumors of the pancreas that typically affect young women and have a favorable prognosis. Herein, we report a 25-year-old female with solid pseudopapillary tumor of the pancreas who presented with atypical epigastric pain. The patient underwent pancreatoduodenectomy (Whipple procedure).

Misfolding of Lysosomal α-Galactosidase a in a Fly Model and Its Alleviation by the Pharmacological Chaperone Migalastat.

Fabry disease, an X-linked recessive lysosomal disease, results from mutations in the gene encoding lysosomal α-galactosidase A (α-Gal A). Due to these mutations, there is accumulation of globotriaosylceramide (GL-3) in plasma and in a wide range of cells throughout the body. Like other lysosomal enzymes, α-Gal A is synthesized on endoplasmic reticulum (ER) bound polyribosomes, and upon entry into the ER it undergoes glycosylation and folding.

Management of malignant and borderline phyllodes tumors of the breast: our experience.

Purpose: Phyllodes breast tumors (PT) range from benign lesions to malignant ones that may give distant metastasis. Preoperative diagnosis is difficult, while the treatment of borderline and malignant disease remains controversial.

Methods: Eighteen patients in 3 clinics were included in the study.

Malignant myoepithelioma of the breast: A case report and review of the literature.

Malignant myoepithelioma of the breast is an extremely rare tumor composed entirely or almost entirely of malignant spindle cells with myoepithelial differentiation. Only a limited number of case reports have been descibed to date; therefore the biological behavior and treatment outcomes of this rare tumor have not been clearly determined. Herein, we present a case of a 74-year-old woman who was admitted with inflammatory-like cancer of the breast, presenting with invasion of the chest wall and axillary lymph node metastasis at the time of diagnosis.

Primary thyroid lymphoma: The two ends of the spectrum.

We describe two different cases of prinary thyroid lymphoma (PTL). PTL is a rare malignancy. Nevertheless, it frequently presents diagnostic and therapeutic challenges.

Identification of MEFV-independent modifying genetic factors for familial Mediterranean fever.

Familial Mediterranean fever (FMF) is a recessively inherited disorder predisposing to renal amyloidosis and associated with mutations in MEFV, a gene encoding a protein of unknown function. Differences in clinical expression have been attributed to MEFV-allelic heterogeneity, with the M694V/M694V genotype associated with a high prevalence of renal amyloidosis. However, the variable risk for patients with identical MEFV mutations to develop this severe complication, prevented by lifelong administration of colchicine, strongly suggests a role for other genetic and/or environmental factors.
