Investigation of hypovitaminosis D in patients infected with SARS-CoV-2 and its relationship with clinical worsening: a cross-sectional observational retrospective clinical study
Get PDFNumerous studies have demonstrated the profile of infection and symptoms related to COVID-19 that occur with pulmonary manifestations (such as Acute Respiratory Syndrome), digestive symptoms, anosmia, and ageusia. Many comorbidities have been associated with deaths and severe cases of the disease, such as diabetes, hypertension, obesity, and heart disease. However, many questions remain unanswered, especially the association of disease severity with hypovitaminosis D. Vitamin D deficiency is widely found in patients in Intensive Care Units, and recent studies have shown that it has been suggested that patients with severe manifestations of COVID-19 have hypovitaminosis D. Therefore, the present study aims to associate the presence of hypovitaminosis D in patients with the acute respiratory syndrome, positive for SARS-COV-2, admitted to the José Alencar Regional Hospital in Uberaba/Brazil and the evolution of the disease (days of hospitalization, hospitalization in the ICU, discharge and death) through the analysis of vitamin D (25(OH)D) hospitalized patients clinical records. The incidence of hypovitaminosis D among the patients was also assessed. The results may contribute to the understanding of the disease, as well as the need for vitamin supplementation
Clinical, cellular and molecular approaches to oxidative stress in athletes' bodies: a systematic and integrative review
Get PDFIntroduction: Frequent physical exercises can cause a state of transient fatigue, thus increasing the regenerative capacity of the body and inducing an overcompensation of the biological systems involved. The state resulting from overtraining has negative consequences not only for physical performance but also for health and when this state occurs, reactive oxygen species (ROS) are synthesized in the body. Objective: It was to carry out a systematic and integrative review of the main clinical, cellular and molecular approaches to oxidative stress in athletes' bodies, as well as the main functions of antioxidants in mitochondria. Methods: The systematic review rules of the PRISMA Platform were followed. The research was carried out from October to December 2022 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, and a total of 67 articles were fully evaluated and 57 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 7 studies at high risk of bias and 25 studies that did not meet the GRADE. Studies have shown that free radicals play important roles as regulators in muscle signaling processes. Oxidative stress reflects an imbalance between the production of reactive oxygen species and adequate antioxidant defense. The relationship between exercise and oxidative stress is extremely complex, depending on the mode, intensity, and duration of exercise. High levels of reactive oxygen species produced in skeletal muscle during exercise have been associated with muscle damage and impaired muscle function. Antioxidant supplementation may be warranted under specific conditions when athletes are exposed to high oxidative stress or do not meet dietary antioxidant requirements. Continuous aerobic exercise under moderate-intensity or high-intensity interval training can be recommended to increase the body's ability to maintain redox balance, especially for unhealthy individuals
Nutritional status of patients at the moment of primary cleft lip and palate surgery: a retrospective observational study
Get PDFObjective: This study aimed to analyze the nutritional status of patients with cleft lip and palate at the time of admission and time of performing primary lip and/or palate surgeries at the Hospital for Rehabilitation of Craniofacial Anomalies of Bauru, Universidade São Paulo. Methods: A retrospective observational study was conducted using medical records of individuals with cleft lip and/or palate who underwent primary lip and/or palate surgeries between 2011 and 2021. Anthropometric data were collected upon hospital admission and before primary lip and/or lip surgery. The Z-scores of the growth curves were calculated according to age and sex using the World Health Organization (WHO) Anthro and WHO AnthroPlus programs. Statistical analysis was performed using the Spearman, analysis of variance (ANOVA), and Student’s t-tests. Results: Of the 218 participants, 50.46% were men, and most of the patients originated from the southeast region (87.16%) with prevalence of cleft palate (52.75%). A correlation was found between weight/height and weight/age indices with the delay in performing primary lip surgery and height/age with the delay in primary palate and lip surgery (Student’s t-test, p < 0.05), and no correlation was found between the nutritional/nutrological status and socioeconomic profile (Spearman correlation test, p < 0.05) and with the place of origin (ANOVA test, p < 0.05). Conclusion: A correlation was found between the weight/height and height/age indices with the delay in performing primary lip surgery and height/age with the delay in primary surgery of the palate and lip
The role of intestinal and vaginal dysbiosis in endometrial cancer: an integrative review
Get PDFThe increase in the incidence of endometrial neoplasms in the female population is associated with increased life expectancy and the lifestyle adopted in our daily lives. The way we eat influences the profile of our bacterial flora and the production of substances that can work as suppressor tumors or oncogenic. Dysbiosis leads to changes in the intestinal and vaginal bacterial barrier and promotes chronic inflammation and metabolic and hormonal changes that influence the carcinogenesis of gynecological tumors. Chemotherapy treatments can also change the composition of the intestinal microbiota and influence the efficacy and toxic effects, as well as the quality of life of these patients. The use of prebiotics, probiotics, or fecal transplantation can be useful both in prevention and in obtaining better results with chemotherapy treatment and better quality of life. The objective of this review is to provide further elucidation about the interaction mechanisms between the intestinal microbiota and the gynecological tract and assess future perspectives through the modification of the feeding pattern, use of prebiotics, probiotics, and fecal transplant both in the prevention and during the treatment of carrier patients of endometrial neoplasm
Iron peptide complex does not increase blood iron concentration at the same extent as ferrous sulfate after oral ingestion in healthy adult males
Get PDFIron-deficient anemia continues to be one of the major nutritional and public health problems all over the world. Although ferrous sulfate is largely used for the prevention and treatment of this deficiency, the gastrointestinal side effects preclude its use in some cases. This study aimed to compare the effect of iron peptide complex and ferrous sulfate on serum iron and to examine serial serum iron levels. Ten volunteers were submitted to 5 different treatments: Control (C), Ferrous sulfate 60 mg (FS), Iron peptide 60 mg (IP1), Iron peptide 80 mg (IP2) and Iron peptide 60 mg plus diet (IPD). In the first treatment (C), empty capsules were given, whereas in the second (FS), third (IP1), fourth (IP2) and fifth (IPD) treatments, ferrous sulfate 60 mg, iron peptide complex 60 mg, iron peptide complex 80 mg and iron peptide complex 60 mg plus diet were given in a randomized crossover design, with a washout period of 1 week. The products were offered as capsules and blood samples were drawn at the following time points: 0, 30, 60, 120, 240, 480 and 720 minutes after oral intake. FS produced higher serum iron levels than Control, IP1, IP2 and IPD (P< 0.05). The areas under the curves for serum iron for the different compounds gave AUCFS > AUCC = AUCIP1 = AUCIP2 = AUCIPD. Conclusions: The iron peptide complex did not increase blood iron FS C IP1 IP2 IPD concentration as compared to control and ferrous sulfate at the respective time points
Determination of lead concentration in breast milk and blood of lactanting women in an interior city of Brasil
Get PDFBackground: breast milk offers numerous advantages biological and emotional. However, in some situations, can transfer harmful elements for the health of infants. Objective: to determine lead levels in the blood and milk of mothers whose children frequent a primary mother-child health care. Methods: a cross-sectional, observational and descriptive study of 70 healthy women who were breast-feeding babies younger than six months during 01/04/2011 to 30/09/2011. Lead determination was performed by mass spectrometry with inductively coupled plasma. A linear regression model was adjusted to determine the association between lead concentrations in maternal milk and blood. The estimated values of the difference between means and their 95% confidence intervals were obtained. Results: mean lead concentration in milk was 1.462 ng/mL and blood lead concentration was 1.801 μg/dL. Conclusions: human milk is not a source of contamination for the babies in this area. However, more studies are needed in other regions of the country in view of the growing evidence of foci of lead contamination, which may represent an occult risk for the population
IL-6: Sinalização na Hipertrofia Muscular e efeitos Metabólicos Sistêmicos
Get PDFThe myokines are substances produced in skeletal muscle by muscle contraction induced by strengthening exercise. They have the ability to act locally on skeletal muscle itself and also in other organs and body tissues. In this review, we discuss relevant aspects presented in scientificliterature with a high degree of evidence signalling Interleukin - 6 (IL-6) in muscle hypertrophy induced by strenght training exercises, and also the action arising from its release by skeletal muscle in the bloodstream, exerting effects on other organs and tissues, demonstrating that it has an important role in the interaction of immunoneuroendocrine system and pro and anti-inflammatory effects in the human body
