Background: Ulcerative colitis (UC) is a chronic inflammatory bowel disease caused by numerous factors, such as immune system dysfunction and genetic factors. MicroRNAs (miRNAs) play a crucial role in UC pathogenesis, particularly via the JAK-STAT pathway. Our aim was to investigate the association between miRNA-101 and JAK2-STAT3 signaling pathway with inflammatory cytokines in UC patients.

Background And Aims: Transient elastography (TE), shear wave elastography, and/or magnetic resonance elastography (MRE), each providing liver stiffness measurement (LSM), are the most studied imaging-based noninvasive liver disease assessment (NILDA) techniques. To support the American Association for the Study of Liver Diseases guidelines on NILDA, we summarized the evidence on the accuracy of these LSM methods to stage liver fibrosis (F).

Approach And Results: A comprehensive search for studies assessing LSM by TE, shear wave elastography, or MRE for the identification of significant fibrosis (F2-4), advanced fibrosis (F3-4), or cirrhosis (F4), using histopathology as the standard of reference by liver disease etiology in adults or children from inception to April 2022 was performed.

Background And Aims: Blood-based biomarkers have been proposed as an alternative to liver biopsy for noninvasive liver disease assessment in chronic liver disease. Our aims for this systematic review were to evaluate the diagnostic utility of selected blood-based tests either alone, or in combination, for identifying significant fibrosis (F2-4), advanced fibrosis (F3-4), and cirrhosis (F4), as compared to biopsy in chronic liver disease.

Approach And Results: We included a comprehensive search of databases including Ovid MEDLINE(R), EMBASE, Cochrane Database, and Scopus through to April 2022.

Background And Aims: Portal hypertension is a serious complication of cirrhosis, which leads to life-threatening complications. HVPG, a surrogate of portal pressure, is the reference standard test to assess the severity of portal hypertension. However, since HVPG is limited by its invasiveness and availability, noninvasive liver disease assessments to assess portal pressure, especially clinically significant portal hypertension (CSPH), are needed.

Background: We aimed to investigate the effectiveness of fixed-dose combination therapy (polypill) for primary and secondary prevention of major cardiovascular diseases in a typical rural setting.

Methods: The PolyPars Study is a two-arm pragmatic cluster-randomised trial nested within the PARS cohort study, including all residents aged over 50 years in the entire district in southern Iran. The 91 villages underwent random allocation into two arms: the control arm, encompassing 45 clusters, was subjected to non-pharmacological intervention (educational training on healthy lifestyle), whereas the intervention arm, comprising 46 clusters, received the non-pharmacological interventions in conjunction with a once-daily polypill tablet.

Background: Management of side effects in clinical trials has to balance generation of meaningful data with risk for patients. A toxicity area requiring detailed management guidelines is drug-induced liver injury (DILI). In oncology trials, patients are often included despite baseline liver test abnormalities, for whom there is no consensus yet on levels of liver test changes that should trigger action, such as drug interruption or discontinuation.

Portal hypertensive gastropathy (PHG) and gastric antral vascular ectasia (GAVE) are 2 distinct gastric vascular abnormalities that may present with acute or chronic blood loss. PHG requires the presence of portal hypertension and is typically associated with chronic liver disease, whereas there is controversy about the association of GAVE with chronic liver disease and/or portal hypertension. Distinguishing between GAVE and PHG is crucial because their treatment strategies differ.

Aortic valve stenosis is the most common type of heart valve disease in the United States and Europe and calcific aortic stenosis (AS) affects 2-7% of people aged 65 years and older. Aortic valve replacement (AVR) is the only effective treatment for individuals with this condition. Transcatheter Aortic Valve Replacement (TAVR) has been widely accepted as a minimally invasive therapeutic approach for addressing symptomatic AS in patients who are considered to have a high risk for traditional surgical intervention.

Diet Quality and Subsequent Incidence of Upper Gastrointestinal Cancers: Results from the Golestan Cohort Study.

Arch Iran Med

September 2023

Genomic Epidemiology Branch, International Agency for Research on Cancer (IARC/WHO), Lyon, France.

Article Synopsis
  • Recent research indicates that overall diet quality is linked to the risk of upper gastrointestinal (UGI) cancers, particularly in high-risk regions like northeastern Iran, where dietary patterns differ from high-income countries.
  • The study followed over 50,000 individuals from 2004 to 2020, using various dietary indices to assess diet quality and found that better dietary scores were associated with reduced risk for both esophageal (up to 12%) and stomach cancers (up to 17%).
  • Notably, specific diets like the Alternative Mediterranean Diet and the World Cancer Research Fund/American Institute for Cancer Research scores showed stronger protective effects against these cancers compared to other dietary scores like the Healthy Eating Index.

Article Synopsis
  • A retrospective study compared the clinical features and treatment of early-onset (children/adolescents) and elderly-onset inflammatory bowel disease (IBD) patients to understand differences in disease manifestation and progression.
  • The study found that early-onset IBD patients commonly had a more aggressive disease phenotype and used more intensive treatments like prednisolone and anti-TNF medications compared to elderly patients.
  • Notably, elderly-onset ulcerative colitis patients exhibited less aggressive disease and were less likely to require the same level of medication as their early-onset counterparts.
