Outcomes of Adolescents and Young Adults Compared with Children with Acute Leukemia after Single-Unit Unrelated Cord Blood Transplantation Using Myeloablative Conditioning without Antithymocyte Globulin.

Acta Haematol 2021 Apr 13:1-11. Epub 2021 Apr 13.

Department of Hematology, Anhui Provincial Hospital, Cheeloo College of Medicine, Shandong University, Jinan, China.

Background: Although the use of cord blood transplantation (CBT) is becoming more frequent in acute leukemia, considering the relationship between the low stem cell dose and graft failure, whether use of CBT for adolescents and young adults (AYAs) is appropriate remains uncertain.

Methods: A retrospective registry-based analysis of clinical outcomes and immune reconstitution was conducted for 105 AYAs and 187 children with acute leukemia who underwent single-unit CBT using myeloablative conditioning (MAC) without antithymocyte globulin (ATG).

Results: Outcomes were similar between AYAs and children, except for nonrelapse mortality (NRM) and recovery rates of neutrophils and platelets. Read More

Does Ghana's National Health Insurance Scheme provide financial protection to tuberculosis patients and their households?

Soc Sci Med 2021 Mar 27;277:113875. Epub 2021 Mar 27.

Department of Infectious Disease Epidemiology, London School of Hygiene and Tropical Medicine, London, United Kingdom.

Financial barriers are a key limitation to accessing health services, such as tuberculosis (TB) care in resource-poor settings. In Ghana, the National Health Insurance Scheme (NHIS), established in 2003, officially offers free TB care to those enrolled. Using data from the first Ghana's national TB patient cost survey, we address two key questions 1) what are the key determinants of costs and affordability for TB-affected households, and 2) what would be the impact on costs for TB-affected households of expanding NHIS to all TB patients? We reported the level of direct and indirect costs, the proportion of TB-affected households experiencing catastrophic costs (defined as total TB-related costs, i. Read More

Tumor necrosis factor-alpha and interferon-gamma induce inflammasome-mediated corneal endothelial cell death.

Exp Eye Res 2021 Apr 10:108574. Epub 2021 Apr 10.

Department of Ophthalmology, Bascom Palmer Eye Institute, University of Miami Miller School of Medicine, Miami, FL, USA; Interdisciplinary Stem Cell Institute, University of Miami Miller School of Medicine, Miami, FL, USA.

Purpose: Chronic corneal endothelial cell (CEC) loss results in corneal edema and vision loss in conditions such as pseudophakic bullous keratopathy (PBK), Fuchs' dystrophy, and corneal graft failure. Low CEC density has been associated with an elevation of intraocular pro-inflammatory cytokines such as tumor necrosis factor (TNF)-α and interferon (INF)-γ. These cytokines are capable of triggering pyroptosis, a programmed cell death mechanism mediated by the inflammasome, prompting the activation of the pro-inflammatory cytokine interleukin (IL)-1β, the perpetuation of inflammation, and subsequent damage of corneal endothelial tissue.

Ecofriendly Solution-Combustion-Processed Thin-Film Transistors for Synaptic Emulation and Neuromorphic Computing.

ACS Appl Mater Interfaces 2021 Apr 13. Epub 2021 Apr 13.

Department of Electrical and Electronic Engineering, Xi'an Jiaotong-Liverpool University, Suzhou 215123, China.

The ecofriendly combustion synthesis (ECS) and self-combustion synthesis (ESCS) have been successfully utilized to deposit high- aluminum oxide (AlO) dielectrics at low temperatures and applied for aqueous InO thin-film transistors (TFTs) accordingly. The ECS and ESCS processes facilitate the formation of high-quality dielectrics at lower temperatures compared to conventional methods based on an ethanol precursor, as confirmed by thermal analysis and chemical composition characterization. The aqueous InO TFTs based on ECS and ESCS-AlO show enhanced electrical characteristics and counterclockwise transfer-curve hysteresis. Read More

Winding up the bloom clock-do sugar levels at senescence determine how trees respond to winter temperature?

Tree Physiol 2021 Apr 13. Epub 2021 Apr 13.

Plant Sciences, UC Davis, USA.

Variable winter temperatures cause a year-to-year discrepancy in the phenology of deciduous trees. It implies that an intrinsic 'winter clock' synchronizes bloom with the progression of winter to spring. The carbohydrate-temperature (C-T) model established a mechanistic association between carbohydrate metabolism in dormant trees and hourly winter temperatures. Read More
