Double expressor lymphoma (DEL) is a subset of diffuse large B-cell lymphoma (DLBCL) characterized by the co-expression of MYC and BCL2 proteins with a poor prognosis. However, there are no standard criteria for evaluating the morphologic features of DEL. We aimed to analyze the prognostic value of the starry-sky pattern (SSP) and its correlation with clinicopathologic and genetic features in 153 DEL cases. The SSP was significantly associated with aggressive parameters, including c-MYC overexpression, CD5 expression, higher IPI, and age-adjusted IPI. In the univariate survival analyses, the presence of SSP was associated with unfavorable progression-free survival (PFS) (p = 0.040), and tended towards an adverse overall survival (OS) (p = 0.061). However, when c-MYC was overexpressed, SSP was significantly correlated with inferior OS (p = 0.019). In the multivariate survival analysis, SSP was also associated with poor PFS (p = 0.048). Additionally, next-generation sequencing data revealed SSP was significantly associated with the KMT2D mutation and had different genetic mutation profiles from non-SSP. In conclusion, SSP may represent morphologic characteristics of aggressiveness in DEL.

Background: We examined racial differences between measures of limbic white matter tracts and objective sleep parameters in cognitively unimpaired older-adults.
Method: This cross-sectional study included 170 community-dwelling cognitively unimpaired older-adults (mean±SD: age = 67.2±5.

Background: Mild behavioral impairment (MBI) is a syndrome that leverages neuropsychiatric symptoms that emerge in later-life, and which persist, to identify individuals at high-risk for incident dementia. Attendant with MBI are changes in quality of life (QoL), which can present concurrent with the onset of cognitive decline or even before. Obtaining information from participants and study partners can provide a broader overview of health and QoL.

Background & objectives Surgical site infections (SSIs) are among the most prevalent healthcare-associated infections (HCAIs). They cause significant morbidity, leading to excess health expenditures and increased length of hospital stay. Despite a high population burden, data on post-discharge SSIs is lacking from low-and middle-income countries (LMICs).

Understanding the establishment of ecological security patterns in arid and semi-arid regions is critical for global ecological risk prevention, control, and sustainable development. Nonetheless, there remains a relative deficiency in ecological risk assessment and construction of Ecological Security Patterns (ESP) in these areas, along with insufficient verification regarding the changes in ecological security patterns under diverse scenarios. This study employs Morphological Spatial Pattern Analysis (MSPA) to identify ecological sources and utilizes circuit theory alongside Minimum Cumulative Resistance (MCR) to delineate ecological corridors.

Integrated genome-wide association study and linkage mapping revealed genetic basis of alkalinity tolerance during rice germination. The key gene OsWRKY49 was further verified in transgenic plants. With the widespread use of the rice direct seeding cultivation model, improving the tolerance of rice varieties to salinity-alkalinity at the germination stage has become increasingly important.
