Aging induces a decline in enzymes involved in the post-translational processing of collagen, reducing the number of fibroblasts that synthesize collagen and the vessels that irrigate the skin. Oral ingestion of hydrolyzed collagen together with vitamins and nutrients (especially apple exosomes) increases the levels of collagenderived peptides in the bloodstream and improves skin properties. Objective: It was to carry out a systematic review to elucidate the main results of clinical studies and meta-analyses of clinical studies on the effects of supplementation of types of collagen, vitamins, and nutrients for the rejuvenation of collagen fibers. Methods: The search was carried out from October to December 2023 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 122 articles were found, and 12 articles were evaluated in full, and 07 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 20 studies with a high risk of bias and 26 studies that did not meet GRADE and AMSTAR-2. Most studies showed homogeneity in their results, with X2=62.4%>50%. Oral nutritional supplements containing collagen peptides can reduce skin vulnerability in the elderly and thus prevent conditions such as skin lesions. The direct effects of collagen peptides on fibroblasts, M2-like macrophages, and mechanisms related to oral tolerance are the possible mechanisms for the beneficial effects of collagen supplementation. Special collagen peptides together with acerola extract, vitamin C, vitamin E, biotin, and zinc showed a significant improvement in the skin's collagen structure. The proven positive nutritional effect on collagen structure was fully consistent with the quality of healthy skin. Finally, apple-derived nanovesicles (exosomes) also reduce the degradation of the extracellular matrix, increasing collagen synthesis (COL3A1, COL1A2, COL8A1, and COL6A1) and negatively regulating the production of metalloproteinases.","PeriodicalId":137919,"journal":{"name":"International Journal of Nutrology","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139383407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By 2030, it is estimated that more than 60% of the world's population will be overweight or obese. The COVID19 pandemic has resulted in the worsening of obesity comorbidities. The primary increase in the inflammatory response in obese patients functions as a predictor for the hyperinflammatory state observed in COVID-19. Therefore, this primary increase can be amplified by SARS-CoV-2 infection, increasing the production of cytokines such as TNF-α, IL-1, and IL-6. Objective: It was to carry out a retrospective longitudinal observational study to quantitatively analyze how cardiovascular comorbidities such as diabetes, hypertension, obesity, smoking, and compromised immunity contribute to the increased risk of life of participants affected by COVID-19. Methods: This study followed a longitudinal observational retrospective design (STROBE). A total of 45 public and official documents from Brazil (ANVISA), WHO (World Health Organization), Pan American Health Organization (PAHO), EASO (The European Association for the Study of Obesity - The European Commission/ National Information on COVID-19, Lancet Resource Centre) and scientific articles were subjected to eligibility analysis and, after that, 32 documents dated from 2019 to 2022 were selected. Results: In total, 3,993,857 participants were found from 32 documents. The highest incidence of deaths occurred in participants who were smokers, had compromised immunity, had diabetes, and were obese. The greatest risk of death was observed among participants who smoke (HR=2.5) and those with compromised immunity (HR=2.1). Despite this, other comorbidities such as diabetes, obesity, and hypertension also presented statistically significant results for the risk of life. It was observed that only the difference between the means of the comorbidities “obesity” and “diabetes” was not statistically significant, with p<0.05, that is, both comorbidities have similar impacts on the worsening and death of participants in the presence of COVID-19. Conclusion: Cardiovascular comorbidities such as diabetes, hypertension, obesity, smoking, and compromised immunity contributed to the increased risk of life in participants affected by COVID-19, especially in those of an older age. The endothelial dysfunction caused by SARS-CoV-2 explains why participants with comorbidities related to blood vessels such as cardiovascular disease, hypertension, diabetes, and obesity are more likely to develop severe COVID-19, even death","PeriodicalId":137919,"journal":{"name":"International Journal of Nutrology","volume":"31 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139008437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surgeries with malabsorptive and mixed techniques cause a deficit in the absorption of micronutrients, including vitamin D. Objective: The objective of this literature review was to investigate studies that verified the impact of vitamin D deficiency on the preand postoperative quality of life of individuals undergoing bariatric surgery. Methods: The search strategy was carried out in the virtual databases PubMed, Scielo, LILACS, Scopus, Web of Science, Embase, and the Virtual Health Library, in addition to gray literature such as Google Scholar, OpenGrey, Ibict/BDTD (Brazilian digital library of theses and dissertations) and ProQuest using the Medical Subject Headings (MeSH) and Health Sciences Descriptors (DeCS) descriptors with Boolean logical operators (AND, OR and NOT. The studies considered potentially eligible were those that presented in the same article the levels of vitamin D in the pre and postoperative period of the individuals, as well as the effect generated on their quality of life from where the data collection and analysis of the main outcomes found were made. Results: The online search resulted in 197 studies located in the virtual bibliographic databases and 115 in the gray literature. After removing the duplicates, 235 articles remained that were read by title and abstract, and 12 articles were chosen for reading the full text, leaving 7 that met the inclusion criteria. In most of the included studies, vitamin D deficiency was higher preoperatively than postoperatively in bariatric individuals. Better levels of 25(OH)D were correlated with reduced body weight, decreased BMI, and improved glycemic profile. Conclusion: Combating obesity remains an important issue in Public Health, with bariatric surgery being a safe way to reduce overweight since vitamin D levels are lower in the postoperative period of bariatric individuals, however, it is suggested to choose the appropriate technique to maintain ideal vitamin indices.","PeriodicalId":137919,"journal":{"name":"International Journal of Nutrology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134905632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Δ9 tetrahydrocannabinol (Δ9-THC) may be responsible for some adverse effects on sports performance and this makes cannabis unattractive for athletes. Extracellular vesicles (exosomes and microRNAs) induced by exercise emerged as potential mediators of tissue crosstalk. Objective: It was to carry out a systematic review study to highlight the main outcomes of cannabidiol in metabolic modulation and microRNA signaling in increasing sports performance. Methods: The systematic review rules of the PRISMA Platform were followed. The research was carried out from March to May 2023 in Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 127 articles were found. A total of 87 articles were evaluated in full and 62 were included and developed in this systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 5 studies with a high risk of bias and 11 studies that did not meet GRADE. It has been shown that cannabidiol exerts some physiological, biochemical, and psychological effects with the potential to benefit athletes. For example, there is preliminary supporting evidence for the anti-inflammatory, neuroprotective, analgesic, and anxiolytic actions of cannabidiol and the possibility that it may protect against gastrointestinal damage associated with inflammation and promote healing of traumatic skeletal injuries. However, it is important to recognize that these findings are very preliminary, sometimes inconsistent, and largely derived from preclinical studies. These studies are limited in their generalizability to athletes and often administer high doses of cannabidiol. The central observation is that there is a lack of studies that directly investigate cannabidiol and sports performance. Furthermore, we identified a specific repertoire of microRNAs that are regulated by cannabinoids, at rest (vigilant), and in microglia activated by lipopolysaccharides. Modulated microRNAs and their target genes are controlled by TLR, Nrf2, and Notch cross-signaling and are involved in the immune response, cell cycle regulation, as well as cellular stress and redox homeostasis.","PeriodicalId":137919,"journal":{"name":"International Journal of Nutrology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135993276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extra-renal hydroxylation of vitamin D also occurs, originating the vitamin that would act in an autocrine and paracrine manner, with functions of inhibiting cell proliferation, promoting cell differentiation, and immune regulation. Objective: It was to review the scientific literature on the role of vitamin D in autoimmunity. Methods: A search was carried out on scientific articles centered on the proposed theme: “Role of vitamin D in autoimmunity”. Several search engines that carried scientific information in the health area were used to carry out this study, such as Google Scholar and the Medical Publications database (PubMed), and Scientific Electronic Library Online (SCIELO). In collecting the information, the descriptors used to carry out this research were: vitamin D; vitamin D in preventing diseases; vitamin D and autoimmune diseases; vitamin D; autoimmune diseases. The inclusion criteria used in this study were publications of scientific articles available in full and with free electronic access, limited to a period between 2011 and 2022, and selected articles in Portuguese and English. Results and Conclusion: Based on this methodology, it was possible to analyze a population of 58 articles that were selected for the study and constituted the sample used in this review. Several studies point to the effects of vitamin D not related to calcium metabolism, such as antineoplastic activity (particularly concerning breast, colon, and prostate cancers, and lymphoproliferative diseases), antihypertensive and immunomodulatory. Vitamin D deficiency and its use for treatment have been described in various autoimmune diseases such as rheumatoid arthritis, multiple sclerosis, lupus, inflammatory bowel disease, myasthenia gravis, scleroderma, alopecia areata, psoriasis, vitiligo, autoimmune hepatitis, type 1 diabetes mellitus, autoimmune thyroiditis, etc. The effects of vitamin D on the immune system are related to the tolerance of self-antigens, exerting an inhibitory effect on the Th1 and Th17 type lymphocyte pattern, and a promoting effect on the expression of the Th2 and Treg pattern through the action of vitamin D in all cells of the system through the vitamin D receptor.
