We studied neuroinflammatory markers in an insulin-deficient state without treatment compared with those found in a treated patient with T1D/DKA of similar age and race who died shortly after treatment. The frontal cortex and hippocampus were stained for tight junction proteins, RAGE, NLRP3, and HMGB1. Other markers that can disrupt the blood-brain barrier, such as IL-17, IL-6, IL-1β, GFAP, and IL-10 were also tested. This case study reveals that neuroinflammatory markers are expressed in the DKA brain at a lower level before treatment than those found to be expressed in the brain after treatment. These findings suggest that in DKA, dehydration minimizes inflammation which could be exacerbated with fluids promoting neuroinflammation and cognitive deficits. These findings require further studies and could identify therapeutic targets to reduce the progression of neuroinflammation and brain edema.</p>","PeriodicalId":54303,"journal":{"name":"Archives of Endocrinology Metabolism","volume":"68 ","pages":"e240074"},"PeriodicalIF":1.6,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11554359/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142636193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review was conducted to evaluate the status of AS for low-risk PTMC in Latin America, including cultural and logistical challenges, disease progression data, and financial viability. We searched PubMed (MEDLINE), SciELO, LILACS, and Web of Science for articles published after 2014 and enrolling adult Latin American patients.

Neck ultrasound and serum levels of thyroglobulin, thyroid-stimulating hormone (TSH), thyroxine (T4), and antithyroglobulin antibodies were included in the follow-up. No cases of new distant metastases were reported, and the outcomes were favorable when surgery was required. Anxiety was the main reason for AS interruption. We conclude that AS can be an acceptable approach and is safe and effective in Latin America, although more prospective studies are needed to consolidate this strategy in our region.

Among women with PCOS, GDF-15 levels were higher in those treated with metformin compared with placebo (p = 0.007). The proteins related to GDF-15 overlapped between the databases, and a significant interaction was found between GDF-15 and proteins related to PCOS and its complications, including those related to estrogen response, oxidative stress, ovarian infertility, interleukin (IL)-18, IL-4, the ratio of advanced glycation end products to their receptor (AGE/RAGE), leptin, transforming growth factor beta (TGF-β), adipogenesis, and insulin.</p><p><strong>Conclusion: </strong>The findings of the present study suggest a relationship between GDF-15 and PCOS and a potential increase in GDF-15 levels with metformin treatment. An additional finding was that GDF-15 could be involved in biologic pathways related to PCOS complications.</p>","PeriodicalId":54303,"journal":{"name":"Archives of Endocrinology Metabolism","volume":"68 ","pages":"e230416"},"PeriodicalIF":1.6,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11460967/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142480740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
