Racial Disproportionality in Autism Over 20 Years: What It Means for Special Education Disability Classifications.

Purpose: This study examines racial and ethnic disparities in autism prevalence using data from three National Longitudinal Transition Studies (NLTS) spanning two decades. This inquiry intends to explore: (1) changes in the educational labels assigned to students with a medical diagnosis of autism over time and (2) the disparities in these changes across different racial and ethnic groups.

Methods: A secondary data analysis of the NLTS was conducted using the SPSS Complex Samples module.

Post-Stroke Timing of ECM Hydrogel Implantation Affects Biodegradation and Tissue Restoration.

Extracellular matrix (ECM) hydrogel promotes tissue regeneration in lesion cavities after stroke. However, a bioscaffold's regenerative potential needs to be considered in the context of the evolving pathological environment caused by a stroke. To evaluate this key issue in rats, ECM hydrogel was delivered to the lesion core/cavity at 7-, 14-, 28-, and 90-days post-stroke.

C-MYC Amplification in Chronic Lymphocytic Leukemia: A Case Report and Review of the Literature.

Chronic lymphocytic leukemia (CLL) is among the most common forms of leukemia diagnosed in the United States. It is associated with a variety of clinically significant genetic abnormalities, including cytogenetic abnormalities that are assessed routinely. Herein, we present a case of CLL for which molecular cytogenetic analysis revealed concomitant deletion of TP53 (17p13.

Cytogenetic Findings in a Case of Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN).

Blastic plasmacytoid dendritic cell neoplasm (BPDCN), previously known as natural killer (NK) cell leukemia/lymphoma, is categorized by the World Health Organization as a sole entity. Most often, BPDCN presents with features of both lymphoma and leukemia. The average age at diagnosis is 60 to 70 years and there are more men than women who are diagnosed with BPDCN.

A Plasma Cell Myeloma Case with an Abnormal Clone with a t(8;22)(q24.1;q11.2) Within the Context of a Hyperdiploid Complex Karyotype.

We report here a 74-year-old male who was seen for recurrent respiratory infections, fatigue, and weight loss in November 2016. Bone marrow biopsy showed 90% involvement by plasma cell myeloma (PCM) [90% plasma cells, 40% cellular bone marrow]. Cytogenetic analysis of the bone marrow showed a complex karyotype described as: 53,Y,add(X)(p22.
