Sports nutrology and gut microbiota: a systematic review
Get PDFIntroduction: Many of the established positive health benefits of exercise have been documented by historic discoveries in the field of exercise physiology. Regular physical training associated with nutritional health has broad health benefits for the gut microbiota, acting positively on almost all organ systems of the body. Objective: It was to analyze the main metabolic pathways modulated by nutrients, gut microbiota, and physical exercise in muscle regeneration and sports performance. Methods: The present study followed a systematic review model (PRISMA). The literary search process was carried out from July to September 2022 and was developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar, with scientific articles from 2004 to 2022. The low quality of evidence was attributed to case reports, editorials, and brief communications, according to the GRADE instrument. The risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: We found 132 studies that underwent eligibility analysis, and then 31 of the 52 total studies were selected for this systematic review. According to the GRADE instrument, most studies showed homogeneity in their results, with I2 =98.9% >50%. The Funnel Plot showed a symmetrical behavior, not suggesting a significant risk of bias in studies with a smaller sample size. A healthy gut microbiota and a positive interaction with the immune system, promoted by diligent nutrological care, can be crucial for the muscle-gut axis and can influence the maintenance of muscle mass and its functionality in athletes. However, dysbiosis resulting from a negative interaction with the immune system can influence muscle wasting disorders. These changes can promote systemic inflammation, with overproduction of the pro-inflammatory cytokines TNF-α, IL-1β, and IL-6. Future studies should clarify whether gut microbiota dysbiosis and nutrient depletion are pathophysiologically associated with muscle wasting disorders and whether exercise can positively influence this supposed gut-muscle axis
The employment of the nutrigenomic tool in the prevention and reduction of obesity problems: a review
Get PDFIntroduction: The use of the nutrigenomics tool in the prevention and reduction of obesity problems. Objective: To discuss, through the literature, the interaction between genes, nutrient, and their association with obesity, to convey to the health professional a broader and more detailed and understandable view of the advantages of using nutrigenomics in the prevention or aggravation of this morbidity condition. Methods: Exploratory bibliographic research for its development, articles found in the scientific electronic databases Scielo, Medline, Bireme, and Latin American Literature in Health Sciences (LILACS) in the area of nutrigenomics indexed in the years 2012 to 2018 were selected. Results: Concerning obesity, several studies prove that the control of the need for food intake is affected by polymorphisms in genes encoding peripheral signaling peptides, such as insulin, leptin, and adiponectin. In addition, it is also affected by energy homeostasis that involves changes in PLIN and UCPs genes. Diets based on nutritional needs, nutritional status, and genotype are factors in the prevention and control of obesity and several chronic diseases. Conclusion: Nutrigenomics represents the latest in nutrition science. Health professionals need to know and scientifically debate this new science, showing the health benefits it grants and directing actions that enable the future insertion of this practice in the context of population programs based on public policies for the construction of new paradigms related to the treatment of obesity
Nutritional therapy in celiac disease: a review of the gluten-free diet as a modulator of cardiovascular risk factors
Get PDFIntroduction: Celiac Disease (CD) is a chronic immune-mediated enteropathy precipitated by dietary exposure to gluten in genetically predisposed individuals. The CD has been reported as a rare disease, with an estimated prevalence of 0.3 to 2% worldwide. Objective: This study aimed to review the literature on the role of a gluten-free diet in cardiovascular risk factors in patients with celiac disease, specifically related to lipid profile, body mass index, and diabetes mellitus. Methods: This is a non-systematic literature review study, carried out from July to October 2017. Relevant publications available in the PubMed and BIREME databases were identified. The literature review included randomized controlled trials, cohort studies, casecontrol studies, and cross-sectional analyses. Results and Conclusion: CD it is a disease of special interest due to its association with other autoimmune disorders, intestinal malabsorption, with specific comorbidities, and because its main control mechanism is dietary therapy: the Gluten-Free Diet. Bearing in mind the increase in the worldwide prevalence of celiac disease and its relationship with cardiovascular risk, which may be attributable both to the pathophysiological role of the disease and to the therapeutic plan (dietary), scientific investment in this sphere of public health becomes more than necessary. The influence of gluten-free diet on the cardiovascular risk parameters studied in this review is still not entirely clear. Some studies have suggested that gluten-free diet may have a beneficial effect on the lipid profile of celiac patients, while others have shown that the diet probably does not change or induce atherosclerosis by raising the lipid profile of these patients. In addition, by altering caloric and glycemic intake, the reviewed studies demonstrated a greater tendency towards hyperglycemia and the development of insulin resistance in celiac patients on gluten-free diet. As well as there was a trend towards an increase in body mass index after the introduction of gluten-free diet. However, some authors report that based on these available data, it is not possible to state whether there is a better or worse cardiovascular risk profile after the introduction of gluten-free diet, and therefore, continuity with clinical studies is necessary
Major aspects of cannabidiol in the interaction with microRNAs and exosomes in the modulation of inflammatory and immunological processes in athletes: a systematic review
Get PDFIntroduction: The correct interaction between elements of the endocannabinoid system plays an important role in the development of the central nervous system. Clinical and preclinical studies suggest that cannabidiol (CBD) may be useful for athletes due to its anti-inflammatory, analgesic, anxiolytic, and neuroprotective properties and its influence on the sleep-wake cycle. In addition, a series of implications for epigenetic processes have also been proven, through changes in the expression of microRNAs responsible for modulating the immune and inflammatory systems. Objective: It was to develop a systematic review study to highlight the main aspects of cannabidiol in the interaction with microRNAs and exosomes in the modulation of inflammatory and immunological processes in athletes. Methods: The systematic review rules of the PRISMA Platform were followed. The research was carried out from February to April 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 228 articles were found, and 84 articles were evaluated in full and 60 were included and developed in this 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 90 studies that did not meet GRADE. CBD has been reported to exert a range of physiological, biochemical, and psychological effects with the potential to benefit human health. For example, there is preliminary supporting evidence for the anti-inflammatory, neuroprotective, analgesic, and anxiolytic actions of CBD and the possibility that it may protect against gastrointestinal damage associated with inflammation and promote the healing of traumatic skeletal injuries. The combination of Δ9-THC and CBD can alter the activity of microRNAs responsible for increasing the biosynthesis of inflammatory mediators, leading to a reduction in the inflammatory profile. 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 CBD. The central observation is that there is a lack of studies that directly investigate CBD and sports performance
Vitamin D deficiency and preterm birth: a comprehensive review
Get PDFIntroduction: Pregnancy and its prognosis are highly influenced by maternal nutritional status before and during pregnancy. We know the importance of adequate macronutrient intake and micronutrient supplementation in the preconception period, during pregnancy and in the puerperium. Objective: This literature review aimed to study the relationship between preterm birth and hypovitaminosis D. Methods: Literature review carried out in the Google Scholar, Virtual Health Library (VHL), SciELO and PubMed databases in period of last 5 year- 2017-2022 (june). Results and Conclusion: recent evidence supports that vitamin D deficiency during pregnancy is associated with an increased risk of preterm birth. It is known that hypovitaminosis D during pregnancy can be a risk factor for preterm birth and all its complications for the newborn. But its isolated supplementation during pregnancy is still not a preventive action with statistically significant benefits in preterm birth. Researchers and physicians should be made aware of this issue to improve prenatal care. Strategies adopted to prevent preterm birth are scarce, and it is hoped that in the posterity the evidence mentioned in this article on the role of vitamin D may help to reduce its incidence and, consequently, mortality and, as such, improve the health of women pregnant women and their respective descendants
Major considerations of clinical findings of eye aesthetic and skin treatment with the use of dietary therapy, plasma, and coenzyme Q10: a systematic review
Get PDFIntroduction: A balanced diet plays an important role in the skin. Bioactive substances, i.e. vitamins, minerals, fatty acids, polyphenols, and carotenoids, with a particular focus on their effects on skin condition. The spotlight is on the skin regeneration technique using plasma. Plasma sublimation leaves an intact and dehydrated epidermis layer that acts as a natural biological dressing. Coenzyme Q10 (CoQ10) is a natural constituent of foods and is also often used in functional foods and supplements. Objective: It was to present a systematic review highlighting the main considerations of clinical findings of ocular aesthetic skin treatment such as blepharoplasty with the use of dietary therapy, plasma, and coenzyme Q10. Methods: The systematic review rules (PRISMA) were followed. The search was carried out from February to March 2023 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases, using scientific articles from 2003 to 2023. 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 154 articles were found. A total of 58 articles were fully evaluated and 52 were included in this systematic review. Considering the Cochrane tool for risk of bias, 42 studies with a high risk of bias and 24 studies that did not meet the GRADE were removed. Most studies showed homogeneity in their results, with X2 =95.7% >50%. The symmetrical funnel plot does not suggest a risk of bias between small sample-size studies. Results and Conclusion: It was concluded that promoting healthy eating habits can benefit the appearance of the skin, delay aging processes and reduce the risk of skin cancer. It is necessary to differentiate the substances that protect and restore the epidermal barrier, ensuring an adequate level of skin hydration and protecting against external factors and damage induced by inflammation (omega-3 and omega-6 fatty acids). Antioxidants and other phytonutrients that scavenge reactive oxygen species and alleviate oxidative damage to the skin also play an important role in preventing and caring for skin aging. It was inferred that the plasma technique enabled the modeling of the eyelids that should be sculpted, reducing excess skin, improving the appearance of the eyelids, rejuvenating the eyes, and reducing eyelid weight, mainly with the concomitant use of coenzyme Q10. Longwave plasma radiofrequency ablation is an effective treatment for non-surgical blepharoplasty. Plasma application has great potential in ocular aesthetics, however, more clinical and histopathological studies are needed to support previous findings and address some safety and efficacy issues
Major clinical outcomes of vitamin D deficiency in inflammatory bowel diseases: a systematic and integrative review
Get PDFIntroduction: Clinical studies have proven the direct correlation of vitamin D deficiency in patients suffering from inflammatory bowel diseases, such as Crohn's disease, with an average age of 41 years and more frequently in women. Vitamin D seems to interact with the immune system through its action on the regulation and differentiation of cells such as lymphocytes, macrophages, and natural killer (NK) cells, in addition to interfering with the production of cytokines. Objective: It was to present, through a systematic review, the main clinical outcomes of the correlation of vitamin D deficiency and inflammatory bowel diseases, highlighting Crohn's disease. Methods: The systematic review rules of the PRISMA Platform were followed. The research was carried out from August to October 2022 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 207 articles were found, and 142 articles were evaluated and 117 were included in this systematic review. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 20 studies with a high risk of bias and 28 studies that did not meet GRADE. Most studies showed homogeneity in their results, with R2 =95.7% >50%. It was shown that the highest prevalence of low serum levels of vitamin D is among patients suffering from Crohn's disease and other inflammatory bowel diseases when compared to a control group. However, more comprehensive studies are still needed, especially those that aim to evaluate serum vitamin D in values related to clinical treatment and also the effects of vitamin D supplementation on disease activity and mucosal healing. Thus, it will be possible to evaluate in a relevant way, the replacement of vitamin D in the remission of Crohn's disease, optimizing the treatment of patients and corroborating the improvement in quality of life
Major considerations in the use of bariatric endoscopic therapy (intragastric balloon) and nutrological therapy in successful weight loss in patients with obesity: a systematic review
Get PDFIntroduction: Obesity is a chronic and multifactorial disease that affects more than 2.2 billion people worldwide. Treatment options for obesity have expanded significantly and include lifestyle changes, pharmacotherapy, endoscopic bariatric therapies, and bariatric surgery. Objective: It was to carry out a systematic review to present the main considerations regarding the use of the intragastric balloon as bariatric endoscopic therapy and nutritional therapy in an attempt to achieve successful weight loss in patients with obesity. Methods: The PRISMA Platform systematic review rules were followed. The search was carried out from June to August 2023 in the Web of Science, 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: 129 articles were found. A total of 34 articles were evaluated in full and 24 were included in this systematic review. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 26 studies with a high risk of bias and 12 studies that did not meet GRADE. Most studies showed homogeneity in their results, with X2 =74.7% >50%. In the challenges against super obesity and comorbidities, the use of endoscopic devices has been reported for many years, with the majority of positive results for patients. These devices are gaining increasing acceptance, and the Food and Drug Administration (FDA) has approved three endoscopic devices for use. Patients should be carefully assessed nutritionally and medication-wise and advised on the most appropriate route. To promote long-term adherence, any dietary intervention must take into account patients' dietary preferences, cultural context, and food availability. Ideally, use a combination of Mediterranean and high-protein diets to promote weight loss based on the patient's preference
Impact on quality of life caused by vitamin D deficiency in bariatric patients: a literature review
Get PDFIntroduction: Bariatric surgery is a procedure performed to control obesity and its associated morbidities. 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
Healthy longevity: a systematic review of nutrological and lifestyle aspects
Get PDFIntroduction: In the context of healthy longevity, quality of life, genetic, environmental, and lifestyle factors can determine the life expectancy of human beings. Nutrition is a key component affecting our health, and several studies show that nutrition also has the potential to increase lifespan. Objective: It was to carry out a systematic review of the impacts of nutrology and lifestyle on the longevity of human beings, as well as to point out the main dietary and lifestyle care based on the results of clinical studies. Methods: The systematic review rules of the PRISMA Platform were followed. The research was carried out from April to July 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 311 articles were found, and 147 articles were evaluated and 47 were included in this systematic review. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 29 studies with a high risk of bias and 51 studies that did not meet GRADE. Most studies showed homogeneity in their results, with X2 =87.3%>50%. There is scientific evidence that nutrients and natural substances of human physiology and biochemistry such as melatonin and coenzyme Q10 control the functions of the immune system. Many metabolic or chronic diseases have been implicated with poor diet and lifestyle. Improved diet quality is associated with reduced all-cause mortality, whereas multivitamins and multimineral supplements can improve life expectancy. Overall well-being is improved when sedentary but sufficiently physically active adults reduce sedentary time and increase physical activity levels. The results of the pandemic indicate there have been a variety of lifestyle changes, physical inactivity, and psychological issues. Still, adults over 40 years old, with children, unemployed, and those living in a macroeconomic region were shown to be more exposed to unhealthy behaviors. The maintenance of dietary intervention through telemedicine can reduce the negative impact of eating habits and physical activity patterns
