Blood Demand Forecasting and Supply Management: An Analytical Assessment of Key Studies Utilizing Novel Computational Techniques.

Use of data-driven methodologies in enhancing blood transfusion practices is rising, leveraging big data, machine learning, and optimization techniques to improve demand forecasting and supply chain management. This review used a narrative approach to identify, evaluate, and synthesize key studies that considered novel computational techniques for blood demand forecasting and inventory management through a search of PubMed and Web of Sciences databases for studies published from January 01, 2016, to March 30, 2023. The studies were analyzed for their utilization of various techniques, and their strengths, limitations, and areas for improvement.

Encapsulated follicular variant of papillary thyroid cancer: are these tumors really benign?

Background: Recent studies suggest that the encapsulated form of follicular variant of papillary thyroid cancer (eFVPTC) behaves more similarly to benign lesions and can be treated with thyroid lobectomy alone instead of total thyroidectomy. To distinguish aggressive cancers from more benign lesions more clearly, the objective of this study was to determine if the eFVPTC behaves less aggressively than the nonencapsulated variant (neFVPTC).

Methods: A prospectively collected endocrine surgery database in our institution was reviewed for all patients with FVPTC on surgical pathology from 1999 to 2012.

Successful salvage chemotherapy and allogeneic transplantation of an acute myeloid leukemia patient with disseminated infection.

Disseminated infection is associated with high mortality in immunocompromised patients. Patients with acute myeloid leukemia (AML) often have an extended duration of neutropenia during intensive induction chemotherapy, consolidation chemotherapy, and hematopoietic stem cell transplantation (SCT). There is no consensus regarding management of invasive disseminated infections in the setting of prolonged neutropenia (Tortorano et al.

Acquired RhD mosaicism identifies fibrotic transformation of thrombopoietin receptor-mutated essential thrombocythemia.

Background: Acquired copy-neutral loss of heterozygosity has been described in myeloid malignant progression with an otherwise normal karyotype.

Case Report: A 65-year-old woman with MPL-mutated essential thrombocythemia and progression to myelofibrosis was noted upon routine pretransplant testing to have mixed field reactivity with anti-D and an historic discrepancy in RhD type. The patient had never received transfusions or transplantation.

Dysadherin specific drug conjugates for the treatment of thyroid cancers with aggressive phenotypes.

Background: EDC1 is a novel type of antibody-drug conjugate which binds and inhibits the Na,K-ATPase on the surface of cancer cells expressing dysadherin. The purpose of this study was to determine the expression of dysadherin in different types of thyroid carcinoma, and evaluate the therapeutic potential of EDC1 for thyroid carcinomas.

Methods: Thyroid tissues from 158 patients were examined for dysadherin expression and correlation with clinicopathological features.

In Situ Hybridization Analysis of miR-146b-5p and miR-21 in Thyroid Nodules: Diagnostic Implications.

Some thyroid nodules such as follicular adenomas (FAs), follicular variant of papillary thyroid carcinomas (FVPTCs), and follicular thyroid carcinomas (FTCs) exhibit similar clinical presentations and gross morphologic appearances. The differential diagnosis of these lesions is sometimes difficult based on morphologic, cytologic, or clinical features alone. miR-146b-5p and miR-21 deregulation has been associated with progression and metastasis of thyroid cancers.

Role of percutaneous needle core biopsy in diagnosis and clinical management of renal masses.

Percutaneous needle core biopsies are routinely performed for renal mass diagnosis in some institutions. Because of limited tissue availability, accurate diagnosis can be challenging, and the role of needle core biopsy (NCB) remains debatable in kidney tumor management. In the present study, we reported our experience in diagnosing renal masses via percutaneous NCB and the role it plays in clinical management of these masses.

The roles of the epithelial-mesenchymal transition marker PRRX1 and miR-146b-5p in papillary thyroid carcinoma progression.

Thyroid carcinoma is the most common endocrine malignancy, and papillary thyroid carcinoma represents the most common thyroid cancer. Papillary thyroid carcinomas that invade locally or metastasize are associated with a poor prognosis. We found that, during epithelial-mesenchymal transition (EMT) induced by transforming growth factor-β1 (TGF-β1), papillary thyroid carcinoma cells acquired increased cancer stem cell-like features and the transcription factor paired-related homeobox protein 1 (PRRX1; alias PRX-1), a newly identified EMT inducer, was markedly up-regulated.

The role of epithelial mesenchymal transition markers in thyroid carcinoma progression.

Understanding the molecular mechanisms involved in thyroid cancer progression may provide targets for more effective treatment of aggressive thyroid cancers. Epithelial mesenchymal transition (EMT) is a major pathologic mechanism in tumor progression and is linked to the acquisition of stem-like properties of cancer cells. We examined expression of ZEB1 which activates EMT by binding to the E-box elements in the E-cadherin promoter, and expression of E-cadherin in normal and neoplastic thyroid tissues in a tissue microarray which included 127 neoplasms and 10 normal thyroid specimens.

Thyroid cancer stem-like cells and epithelial-mesenchymal transition in thyroid cancers.

Cancer stem-like cells are a subpopulation of self-renewing stem cells in cancers that are more resistant to chemotherapy and radiation therapy. Evidence supporting the existence of cancer stem-like cells in thyroid and in many other solid tissue cancers is rapidly accumulating. These cells have been studied using specific biomarkers such as CD133, CD44, and aldehyde dehydrogenase enzymes.

Stem cells and cancer stem-like cells in endocrine tissues.

Cancer stem-like cells are a subpopulation of self-renewing cells that are more resistant to chemotherapy and radiation therapy than the other surrounding cancer cells. The cancer stem cell model predicts that only a subset of cancer cells possess the ability to self-renew and produce progenitor cells that can reconstitute and sustain tumor growth. Evidence supporting the existence of cancer stem-like cells in the thyroid, pituitary, and in other endocrine tissues is rapidly accumulating.

Expression of epithelial-mesenchymal transition regulators SNAI2 and TWIST1 in thyroid carcinomas.

Epithelial-mesenchymal transition is an important mechanism of epithelial tumor progression, local invasion and metastasis. The E-cadherin (CDH1) repressor SLUG (SNAI2) and the basic helix-loop-helix transcription factor TWIST1 inhibit CDH1 expression in poorly differentiated malignancies as inducers of epithelial-mesenchymal transition. Epithelial-mesenchymal transition has been implicated in progression from well to poorly differentiated/anaplastic thyroid carcinoma but the expression of SNAI2 and TWIST1 proteins and their phenotypic association in human thyroid cancers has not been extensively studied.
