Risk Factors and Comorbidities of Recurrent Nasal Polyposis.

Chronic rhinosinusitis is divided into two groups, which are Chronic rhinosinusitis with nasal polyps (CRSwNP) and without nasal polyps (CRSsNP). The rate of post-surgical recurrence in the CRSwNP is high, and predicting factors are unknown. This study aims to identify and evaluate risk factors associated with treatment-resistant and recurrent CRSwNP.

Regional response to light illuminance across the human hypothalamus.

Light exerts multiple non-image-forming biological effects on physiology including the stimulation of alertness and cognition. However, the subcortical circuitry underlying the stimulating impact of light is not established in humans. We used 7 Tesla functional magnetic resonance imaging to assess the impact of variations in light illuminance on the regional activity of the hypothalamus while healthy young adults (N=26; 16 women; 24.

Association of oral manifestations with severity of the disease in ulcerative colitis patients.

Objective: Inflammatory bowel diseases (IBD), such as Crohn's disease (CD) and ulcerative colitis (UC), are chronic conditions primarily affecting the intestines.

Methods: This descriptive-analytical study involved ulcerative colitis patients who visited the gastroenterology clinic at Shahid Sayad Shirazi Hospital in Gorgan, along with an equal number of healthy companions as a control group in 2019.

Bacteroides fragilis in saliva: investigating links with ulcerative colitis.

Background: Ulcerative colitis (UC) is a long-term bowel inflammation of unknown cause. Recent research points to gut microbiota, especially Enterotoxigenic Bacteroides fragilis (ETBF), in UC's development. This study examined the presence of Bacteroides fragilis (B.
