Understanding the public knowledge, attitude, and practice toward screening and risk factors of lung cancer in Saudi Arabia: A cross-sectional study.

Context: Early detection of lung cancer through screening can improve outcomes; yet public knowledge, attitudes, and practices regarding lung cancer screening in Saudi Arabia are limited.

Aims: The aim is to assess knowledge, attitudes, and practices toward lung cancer risk factors and screening, and understand the impact of demographic factors on these variables.

Settings And Design: An observational cross-sectional study was conducted from October 2023 to March 2024, involving 708 participants.

Bone marrow mesenchymal stem cells expressing Neat-1, Hotair-1, miR-21, miR-644, and miR-144 subsided cyclophosphamide-induced ovarian insufficiency by remodeling the IGF-1-kisspeptin system, ovarian apoptosis, and angiogenesis.

Ovarian insufficiency is one of the common reproductive disorders affecting women with limited therapeutic aids. Mesenchymal stem cells have been investigated in such disorders before yet, the exact mechanism of MSCs in ovarian regeneration regarding their epigenetic regulation remains elusive. The current study is to investigate the role of the bone marrow-derived mesenchymal stem cells (BM-MSCs) lncRNA (Neat-1 and Hotair1) and miRNA (mir-21-5p, mir-144-5p, and mir-664-5p) in mitigating ovarian granulosa cell apoptosis as well as searching BM-MSCs in altering the expression of ovarian and hypothalamic IGF-1 - kisspeptin system in connection to HPG axis in a cyclophosphamide-induced ovarian failure rat model.

Design and implementation of a scalable high-performance computing (HPC) cluster for omics data analysis: achievements, challenges and recommendations in LMICs.

Background: The advent of high-throughput technologies, including cutting-edge sequencing devices, has revolutionized biomedical data generation and processing. Nevertheless, big data applications require novel hardware and software for parallel computing and management to handle the ever-growing data size and analysis complexity. On-premise, high-performance computing (HPC) is increasingly used in biomedical research for big data stewardship.

Total and Out-of-Pocket Costs Surrounding Emergency Department Care Among Older Adults Enrolled in Traditional Medicare and Medicare Advantage.

Study Objective: We sought to quantify differences in total and out-of-pocket health care costs associated with treat-and-release emergency department (ED) visits among older adults with traditional Medicare and Medicare Advantage.

Methods: We conducted a repeated cross-sectional analysis of treat-and-release ED visits using 2015 to 2020 data from the Medicare Current Beneficiary Survey. We measured total and out-of-pocket health care spending during 3 time periods: the 30 days prior to the ED visit, the treat-and-release ED visit itself, and the 30 days after the ED visit.
