Association of ANRIL Gene Polymorphisms with Gastric Cancer Risk: A Case-Control Study.

Gastric cancer's (GC) cause is unknown, but its complexity indicates that, in addition to environmental factors, it may have genetic origins. Scientists are studying single-nucleotide polymorphisms (SNPs) in the antisense noncoding RNA in the INK4 locus (ANRIL) gene, which encodes a long noncoding RNA molecule. They found a link between the ANRIL gene product and some polymorphisms and GC, suggesting genetic changes may lead to precancerous conditions.

Peripheral blood mononuclear cells show markers of mitochondrial dysfunction in rheumatoid arthritis.

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease. Metabolic and mitochondrial dysregulation are critical causal factors in the pathogenesis and progression of RA. Mitochondrial dysfunction include abnormal energy metabolism, and excessive production of reactive oxygen species (ROS).

Exploring the driving forces and scenario analysis for catastrophic and impoverishing health expenditures in Iran.

Background: The extent of healthcare expenditure within households stands as a crucial indicator in low and middle-income countries (LMICs). When out-of-pocket healthcare expenses surpass household income or become unduly burdensome, it serves as a significant socio-economic alarm, resulting in a reduced quality of life, a phenomenon referred to as 'catastrophic health expenditure (CHE).' Multiple factors can contribute to the occurrence of CHE.

Non-COVID-19 hospitalization and mortality during the COVID-19 pandemic in Iran: a longitudinal assessment of 41 million people in 2019-2022.

Background: During a COVID-19 pandemic, it is imperative to investigate the outcomes of all non-COVID-19 diseases. This study determines hospital admissions and mortality rates related to non-COVID-19 diseases during the COVID-19 pandemic among 41 million Iranians.

Method: This nationwide retrospective study used data from the Iran Health Insurance Organization.
