Article Synopsis
- * Data from 220 patients was collected and analyzed, showing that decreased physical activity, lower body mass index (BMI), and inorganic phosphorus levels were significant factors influencing sarcopenia.
- * The findings highlight the critical role of maintaining physical activity and a healthy BMI to possibly mitigate sarcopenia and its severity in these patients.
Background: The prevalence of pre-frailty is notably high among maintenance hemodialysis (MHD) patients. Pre-frailty, an early and reversible condition between non-frailty and frailty, can lead to adverse outcomes such as increased unplanned hospital admissions and a higher risk of other chronic diseases. Early identification and intervention of pre-frailty in MHD patients are crucial.

To meet these requirements, we developed FE cathodes based on high-quality wrinkled multilayer graphene (MLG) prepared using the bubble-assisted chemical vapor deposition (B-CVD) method and investigated their emission characteristics. The result showed that MLG cathodes prepared using the spin-coating method exhibited a high field emission current density (~7.

- Black silicon (BS) is a nanostructured silicon surface that shows promise for use as field emission (FE) cathodes due to its many sharp tips and ease of fabrication.
- Evaluating the FE performance of BS is complex due to its rough surface morphology, necessitating effective modeling techniques.
- A new 3D modeling method has been developed to characterize BS-based field emitters, linking morphology details with electric field distribution and improving the precision of FE performance assessments, ultimately aiding the design of BS materials for electron emission applications.
Purpose: To develop an assistant tool based on machine learning for early frailty screening in patients receiving maintenance hemodialysis.
Methods: This is a single-center retrospective study. 141 participants' basic information, scale results and laboratory findings were collected and the FRAIL scale was used to assess frailty.
