Feature selection reveal peripheral blood parameter's changes between COVID-19 infections patients from Brazil and Ecuador. | LitMetric

AI Article Synopsis

Article Abstract

The investigation of conventional complete blood-count (CBC) data for classifying the SARS-CoV-2 infection status became a topic of interest, particularly as a complementary laboratory tool in developing and third-world countries that financially struggled to test their population. Although hematological parameters in COVID-19-affected individuals from Asian and USA populations are available, there are no descriptions of comparative analyses of CBC findings between COVID-19 positive and negative cases from Latin American countries. In this sense, machine learning techniques have been employed to examine CBC data and aid in screening patients suspected of SARS-CoV-2 infection. In this work, we used machine learning to compare CBC data between two highly genetically distinguished Latin American countries: Brazil and Ecuador. We notice a clear distribution pattern of positive and negative cases between the two countries. Interestingly, almost all red blood cell count parameters were divergent. For males, neutrophils and lymphocytes are distinct between Brazil and Ecuador, while eosinophils are distinguished for females. Finally, neutrophils, lymphocytes, and monocytes displayed a particular distribution for both genders. Therefore, our findings demonstrate that the same set of CBC features relevant to one population is unlikely to apply to another. This is the first study to compare CBC data from two genetically distinct Latin American countries.

Background: Platelets are associated with poor prognosis in most tumors, but their specific pathogenic mechanism in osteosarcoma is not yet clear. The objective of this study is to conduct an in-depth analysis of how genes closely related to platelet function impact the prognosis of osteosarcoma patients. We hope that through this research, we can uncover the potential mechanisms of these genes in the development and progression of osteosarcoma, thereby providing new therapeutic strategies and theoretical foundations for improving the prognosis of osteosarcoma patients.

High platelet-to-albumin ratio is associated with 30-day mortality in critically ill patients.

Background: The role of inflammation and hypoproteinemia in influencing outcomes of critically ill patients has been widely recognized. However, there is a paucity of research on the prognostic value of the platelet-to-albumin ratio (PAR) in critically ill patients. Therefore, the aim of this study is to assess the prognostic significance of PAR in this population.

The aim of the present study was to employ CELLSEARCH technology for the detection of circulating tumor cells (CTCs) in the peripheral blood of head and neck cancer (HNC) patients, and to assess the association between CTC count and patient prognosis. In this retrospective study, a cohort of 56 patients diagnosed with HNC and receiving treatment at the Department of Otolaryngology, Head and Neck Surgery (Beijing Tongren Hospital) between December 2013 and June 2018 were selected. Utilizing CELLSEARCH technology, the presence of CTCs were detected in samples of peripheral blood from patients with head and neck cancer (HNC) patients, and CTC counts were documented.

Background: The rate of immune reconstitution after allogeneic hematopoietic stem cell transplantation (allo-HSCT) plays the principal role in the development of serious post-transplant complications. However, the post-transplantation course has a significant impact on shaping the immune system of the recipient, per se, thus representing risk factors for subsequent unfavorable outcomes. The predictive power of an interferon gamma (IFNγ) release assay (IGRA) on graft-versus-host disease (GVHD) or hematological relapse in recipients of allo-HSCT treated with post-transplantation cyclophosphamide and the impact of these complications on the restoration of cellular immune responsiveness was evaluated.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a liver disease that is strongly associated with chronic low-grade inflammation. Stage 3 of MASLD is characterized by excessive formation of connective tissues, commonly referred to as liver fibrosis. Although numerous inflammatory markers have been identified and extensively studied, including the tumor necrosis factor-α and interleukin-6 have been studied [Byrne CD, Targher G.
