Background: Nanofat was introduced by Tonnard and Verpaele in 2013. Their initial observations in intradermal applications showed improvement in the appearance of the skin. Since then, a number of Nanofat devices have been introduced. The cellular content in the processing of Nanofat is not the same in every device, yet the cellular composition is responsible for the biologic action of Nanofat. The authors sought to find a different means to produce a matrix rich Nanofat to optimize the cellular content.
Objectives: The primary objective of this study was to compare cell counts, cultures, and cell viabilities produced by LipocubeNano (Lipocube, Inc., London, UK) in comparison to Tulip's NanoTransfer (Tulip Medical, San Diego, CA) processing methods.
Methods: Twenty milliliters of fat were harvested from 10 patients in order to test two methods of Nanofat production. Ten milliliters of fat were used to assess each method and, after the final product was obtained, enzymatic digestion for stromal vascular fraction (SVF) isolation was performed. A Muse Flow-cytometer was used to measure cell counts and cell viabilities, cell cultures were performed, and cell images were taken with a florescent microscope.
Results: The LipocubeNano was shown to be superior to Tulip's NanoTransfer system of progressive downsizing with final filtering, which appeared to trap more fibrous tissue leading to lower amounts of SVF. LipocubeNano resulted in higher cell counts (2.24 × 10/cc), whereas Tulip's NanoTransfer method resulted in a lower cell count at 1.44 × 10/cc. Cell viability was the same (96.05%) in both groups.
Conclusions: Nanofat from LipocubeNano has a higher regenerative cell count and more SVF cells than the other common mechanical method of Nanofat processing. This new means of mechanical processing preserves more matrix, optimizing the cellular content of the Nanofat, thus having potentially a higher regenerative effect.

A wealth of research focused on African American populations has connected rs2814778-CC ("Duffy-null") to decreased neutrophil (neutropenia) and leukocyte counts (leukopenia). While it has been proposed that this variant is benign, prior studies have shown that the misinterpretation of Duffy-null associated neutropenia and leukopenia can lead to unnecessary bone marrow biopsies, inequities in cytotoxic and chemotherapeutic treatment courses, under-enrollment in clinical trials, and other disparities. To investigate the phenotypic correlates of Duffy-null status, we conducted a phenome-wide association study (PheWAS) across more than 1,400 clinical conditions in All of Us, the Vanderbilt University Medical Center's Biobank, and the Million Veteran Program.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne disease with a high fatality rate. The clinical diagnosis criteria mainly rely on white blood cell (WBC) and platelet (PLT), which, however, are of limited usage in identifying atypical SFTS. A multicenter study was performed in two hospitals from 2011 to 2023.

Objectives: To explore the predictive factors for non-response to intravenous immunoglobulin (IVIG) in children with Kawasaki disease (KD) and to establish an IVIG non-response prediction scoring model for the Sichuan region.
Methods: A retrospective study was conducted by collecting clinical data from children with KD admitted to four tertiary hospitals in Sichuan Province between 2019 and 2023. Among them, 940 children responded to IVIG, while 74 children did not respond.

Objective: Long-term management of people living with HIV (PLWHs) often relies on CD4 T cell counts for assessing immune recovery, yet a single metric offers limited information. This study aimed to explore the association between the CD4/CD8 ratio and T lymphocyte activities in PLWHs.
Methods: 125 PLWHs and 31 HIV-uninfected controls (UCs) were enrolled and categorized into four groups based on their CD4/CD8 ratios: extremely low ratio (ELR) group: 0.
