Insights & Discussion
The diet might influence the onset and pathophysiology of ulcerative colitis, and can potentially be used in its management.
The methodology used in reviewed studies relies typically on both epidemiological and experimental approaches to examine the relationship between diet and the onset and progression of ulcerative colitis. A combination of observational data from patients and well-structured randomized control trials have been undertaken, investigating both the potential causative effects of diet and its role in symptom management.
In discussing the results, it is suggested that dietary factors do play a significant role in both the onset and the progression of ulcerative colitis. Though more data is needed through further trials, preliminarily, the manipulation of diet appears to have potential in managing the disease, indicating that dietary changes could either alleviate symptoms or trigger disease relapse. This points to an important role of diet in the approach to ulcerative colitis, a significant divergence from previous understandings of the disease.

Systematic Review Acupuncture Moxibustion Ulcerative Colitis
Methodology: This evaluative study used an extensive and systematic methods to search data from seven different databases. The selected data were further refined by using different screening and evaluation frameworks like AMSTAR-2, PRISMA, ROBIS, and GRADE systems. These were used to determine the methodological quality, reporting quality, risk of bias, and the quality of evidence in the selected studies.
Discussion of results: After critical evaluation, the study found ten relevant reviews and analyses that showed potential for acupuncture and moxibustion therapies being effective in ulcerative colitis treatment. However, many the identified studies were reported to have several problems in their overall design and quality of outcomes. The researchers therefore stress caution when interpreting these results due to the lack of high-quality evidence in the existing studies.

Meta-Analysis Acupuncture Moxibustion Ulcerative Colitis
Methodology: The researchers carried out a systematic review and network meta-analysis of clinical efficacy of various acupuncture therapies for ulcerative colitis patients. They accomplished this by sourcing for Clinical Randomized Controlled trial articles from databases such as PubMed, Embase, Cochrane Library, and other data knowledge service platforms, all of which were independently reviewed by two researchers. Several quality assessments were made through Review Manager software, and the meta-analysis was conducted with Stata 16 software. Interventions examined in the analysis included acupuncture, moxibustion, acupoint catgut embedding, and combinations of these therapies with Western medicine.
Discussion of results: 52 articles encompassing 3924 patients participated in randomized control trials. The investigation revealed a range of interventions, including different acupuncture therapies and combinations of these therapies with Western medicine. Namely, moxibustion, either on its own or combined with Western medicine, consistently surfaced as top-ranked for overall effectiveness and specific outcomes. Moreover, moxibustion displayed impressive performance in reducing adverse reactions and recurrence rates. Thus, various acupuncture therapies were confirmed as safe and effective for the treatment of ulcerative colitis, with moxibustion emerging as the most effective.
A combined Mediterranean, low-FODMAP diet along with partial enteral nutrition has shown promise in reducing ulcerative colitis activity and improving patients' quality of life.

Randomised Controlled Trial Low FODMAP Ulcerative Colitis
In the study, fifty patients with active, mild to moderate ulcerative colitis were randomly allotted one of two diets: a combined Mediterranean, low-FODMAP diet supplemented with partial enteral nutrition, or a standard diet. These diets were implemented for a duration of 6 weeks. Before and after the intervention, various indicators of the patients' conditions were measured. These variables included a disease activity index, the patients' quality of life, and concentrations of various inflammatory and oxidative stress factors in the blood. All of these were measured using tested and trustworthy questionnaires, in conjunction with blood sampling.
The combined diet was found to result in significantly decreased disease activity index values, compared to both the control diet and the baseline data. Simultaneously, patients on the combined diet reported greater enhancements in their quality of life, compared to both the control group and the initial data. Lastly, the serum level of a protein called "high sensitive C-reactive protein," known to be a general marker of inflammation within the body, was found to be reduced in the combined diet group. However, changes in the serum total antioxidant capacity were found to be statistically insignificant across both groups.
Despite diet being key in shaping gut microbiota, it surprisingly does not impact the treatment outcomes in individuals with Rheumatoid Arthritis.

Review Article Diet Rheumatoid Arthritis
The process used to understand this paradox involved an umbrella review. This is an examination of multiple research studies and papers that address a similar question, in this case, the effects of diet on Rheumatoid Arthritis (RA). Through a comprehensive analysis of various scientific studies, researchers sought to determine if there was a meaningful link between diet and outcomes in RA patients.
The results of this study revealed an unexpected conclusion. Despite the gut microbiota's critical role in shaping the risk of RA, the data showed that diet, which is a dominant factor in shaping our gut microbiota, did not appear to affect the treatment outcomes in individuals with RA. This finding is surprising given the generally accepted understanding of the influence of diet on gut health and correlates with disease states. This conclusion introduces a new perspective in the understanding of RA and its relationship with diet.

Animal Study Gut Microbiota Intestinal Barrier Snow Fungus
The methodology used in this research involved isolating TA 2-1, a specific polysaccharide from Tremella Aurantialba, and studying its effects on ulcerative colitis. This was done by introducing it to Caco-2 cells that were undergoing ferroptosis and assessing its impact on cell viability. The influence of TA 2-1 was also examined in mice with artificially induced ulcerative colitis, verifying its ameliorating effects in an in-vivo context. The structure of TA 2-1 and its components were analysed and the polysaccharide's interaction with gut microbiota was explored to understand how it might modulate symptoms or prevent cell death.
The results of this study showed that TA 2-1 does not only decrease the rate of cell death in epithelial cells undergoing ferroptosis, but it also repairs the intestinal barrier by upregulating specific proteins such as claudin-1 and zonula occludens-1. TA 2-1 was also found to suppress lipid peroxidation, thus inhibiting ferroptosis. Further investigation revealed that TA 2-1 may alleviate ulcerative colitis by influencing the composition or metabolites of gut microbiota. This research offers promising insight into the potential of TA 2-1 in treating ulcerative colitis.
