Ulcerative colitis (UC) is a chronic inflammatory bowel disease. Recent studies have shown that dietary factors play an important role in the development of UC. Index of Nutritional Quality (INQ) is a suitable method that analyzes quantitatively and qualitatively single foods, meals, and diets. The aim of this study was to determine the association between INQ and UC. ⋯ Our results indicate that enough consumption of Vitamin C and folate was associated with lower risk of UC.

Observational Study
Hypovitaminosis C and vitamin C deficiency in critically ill patients despite recommended enteral and parenteral intakes.
Vitamin C is an essential water-soluble nutrient which cannot be synthesised or stored by humans. It is a potent antioxidant with anti-inflammatory and immune-supportive roles. Previous research has indicated that vitamin C levels are depleted in critically ill patients. In this study we have assessed plasma vitamin C concentrations in critically ill patients relative to infection status (septic shock or non-septic) and level of inflammation (C-reactive protein concentrations). Vitamin C status was also assessed relative to daily enteral and parenteral intakes to determine if standard intensive care unit (ICU) nutritional support is adequate to meet the vitamin C needs of critically ill patients. ⋯ Critically ill patients have low vitamin C concentrations despite receiving standard ICU nutrition. Septic shock patients have significantly depleted vitamin C levels compared with non-septic patients, likely resulting from increased metabolism due to the enhanced inflammatory response observed in septic shock.

The aim was to investigate the protective effect of vitamin C on tissue damage and oxidative stress following tunica albuginea incision with tunica vaginalis flap coverage for testicular torsion. ⋯ The results showed that the histological parameters and testosterone levels improved with the administration of vitamin C before tunica vaginalis flap coverage in the group experiencing 5h of torsion. This may be a result of the antioxidant effect of vitamin C. No advantage was observed for the 9h group, possibly because the dosage of vitamin C was inadequate.

The global burden of sepsis is estimated as 15 to 19 million cases annually, with a mortality rate approaching 60% in low-income countries. ⋯ Our results suggest that the early use of intravenous vitamin C, together with corticosteroids and thiamine, are effective in preventing progressive organ dysfunction, including acute kidney injury, and in reducing the mortality of patients with severe sepsis and septic shock. Additional studies are required to confirm these preliminary findings.

Review Meta AnalysisEfficacy of vitamin C in preventing complex regional pain syndrome after wrist fracture: A systematic review and meta-analysis.
Complex regional pain syndrome type I (CRPS-I), previously known as reflex sympathetic dystrophy, is common after conservatively or surgically treated wrist fractures. Several studies support the efficacy of vitamin C in preventing CRPS-I, although the data are somewhat conflicting. The primary objective of this systematic literature review and meta-analysis was to assess the efficacy of vitamin C therapy in preventing CRPS-I after a wrist fracture. ⋯ II, systematic review of level I and II studies.
