Risk of malignant lymphoma in patients with previous tuberculosis infection: a cohort study.

Tuberculosis (TB) is associated with chronic inflammation, which has been implicated in the pathogenesis of various malignancies, including lung cancer. However, the relationship between TB and hematological malignancies like lymphoma remains less understood. This study aimed to investigate risks of incident malignant lymphoma according to previous TB infection in a large prospective cohort of 347,204 individuals.

Impact of Multidrug-Resistant Bacterial Colonization on Clinical Characteristics, Antibiotic Treatment, and Clinical Outcomes of Hospital-Acquired Pneumonia.

Purpose: To determine effects of colonization with multidrug-resistant bacteria (MDRB) in general wards on characteristics, treatment, and prognosis of hospital-acquired pneumonia (HAP).

Methods: This was a multicenter retrospective cohort study of patients with HAP admitted to 16 tertiary or university hospitals in Korea from July 2019 to December 2019. From the entire cohort, patients who developed pneumonia in general wards with known colonization status before the onset of pneumonia were included in this study.

Revisiting the genus (Liliaceae) in Kazakhstan, the country with the richest tulip diversity worldwide.

The genus L., belonging to the Liliaceae family, has significant economic, horticultural, and ecological importance and is culturally revered in various regions worldwide. The total number of species, including 90-120 taxa, varies based on different sources.

Enhancing the Ground Truth Disparity by MAP Estimation for Developing a Neural-Net Based Stereoscopic Camera.

This paper presents a novel method to enhance ground truth disparity maps generated by Semi-Global Matching (SGM) using Maximum a Posteriori (MAP) estimation. SGM, while not producing visually appealing outputs like neural networks, offers high disparity accuracy in valid regions and avoids the generalization issues often encountered with neural network-based disparity estimation. However, SGM struggles with occlusions and textureless areas, leading to invalid disparity values.

EPRS1-mediated fibroblast activation and mitochondrial dysfunction promote kidney fibrosis.

Kidney fibrosis causes irreversible structural damage in chronic kidney disease and is characterized by aberrant extracellular matrix (ECM) accumulation. Although glutamyl-prolyl-tRNA synthetase 1 (EPRS1) is a crucial enzyme involved in proline-rich protein synthesis, its role in kidney fibrosis remains unclear. The present study revealed that EPRS1 expression levels were increased in the fibrotic kidneys of patients and mice, especially in fibroblasts and proximal tubular epithelial cells, on the basis of single-cell analysis and immunostaining of fibrotic kidneys.
