Sedentary behaviors (SBs), which are low-energy, wakeful activities performed in a sitting, reclining, or lying posture, are independently associated with numerous adverse health outcomes, including mental health disorders, non-communicable diseases, and an increased risk of mortality. This study investigated associations between sociodemographic characteristics, lifestyle factors, mental health, nutritional status, social support, functional limitations, and SB among older persons in Malaysia. Data from 3977 individuals aged 60 years and above, extracted from the National Health and Morbidity Survey (NHMS) 2018, were analyzed using complex samples logistic regression.

Colorectal cancer (CRC) is well characterized in terms of genetic mutations and the mechanisms by which they contribute to carcinogenesis. Mutations in APC, TP53, and KRAS are common in CRC, indicating key roles for these genes in tumor development and progression. However, for certain tumors with low frequencies of these mutations that are defined by tumor location and molecular phenotypes, a carcinogenic mechanism dependent on BRAF mutations has been proposed.

The severe acute respiratory syndrome coronavirus 2 pandemic has raised public awareness about the importance of hygiene, leading to an increased demand for antimicrobial surfaces to minimize microbial contamination on high-touch surfaces. This is particularly relevant in public and private transportation settings, where surfaces frequently touched by individuals pose a significant, yet preventable, risk of infection transmission. Typically, the antimicrobial activity of surfaces is tested using test methods of the International Standards Organization, American Society for Testing and Materials, or Japanese Industrial Standards, which involve complete submersion in liquid, elevated temperature (37°C), and prolonged (24 h) contact periods.

Background/aim: Lung adenocarcinoma (LUAD) or lung squamous cell carcinoma (LUSC) accounts for the majority of non-small cell lung cancer (NSCLC), and overexpression of programmed death ligand 1 (PD-L1) in these cells is known to induce tumor immune evasion or drug resistance. However, detailed studies are needed to determine whether microRNAs (miRNAs) that reduce PD-L1 expression can suppress drug resistance in NSCLC.

Materials And Methods: Kaplan Meier plotter and Receiver Operating Characteristic plotter were used to determine the effect of specific miRNAs on survival and chemotherapy response in NSCLC patients.

Rape myths-false but widely held beliefs that serve to deny and justify sexual aggression-present a major barrier to reporting and prevention of sexual violence in Vietnam and globally. Based on a parent study aimed at reducing sexual violence at two universities in Hanoi, we developed and assessed a contextualized measure of rape myths among young people in Vietnam. Items from previously validated rape myth acceptance (RMA) scales and data from qualitative research informed the development of 50 items, which were administered to Vietnamese 18-24-year-olds (n = 2,756 total, n = 1,798 cisgender women) via an anonymous link in February 2021.
