O combate à pandemia da COVID-19 se tornou o grande desafio atual, e a terapia nutricional é parte fundamental do cuidado integral na atenção ao paciente crítico. A maioria dos pacientes contaminados tem sido tratada em casa, em isolamento domiciliar. Entretanto, uma parte destes pacientes complica e necessita hospitalização, e cerca de 5% precisam de terapia intensiva. Neste subgrupo, as complicações mais frequentes são a disfunção respiratória, seguida da disfunção renal. Sendo assim, BRASPEN/AMIB divulgam, a seguir, sugestões para orientar as equipes multidisciplinares de terapia nutricional (EMTNs) no nosso País
Background:Manipulating intestinal microbiota with probiotics might stimulate skin response. Understanding all stages of the healing process, as well as the gut-skin-healing response can improve the skin healing process. Aim:To evaluate the effect of perioperative oral administration of probiotics on the healing of skin wounds in rats. Methods:Seventy-two Wistar male adult rats were weighed and divided into two groups with 36 each, one control group (supplemented with oral maltodextrin 250 mg/day) and one probiotic group (supplemented with Lactobacillus paracasei LPC-37, Bifidobacterium lactis HN0019, Lactobacillus rhamnosus HN001, Lactobacillus acidophilus NCFM® at a dose of 250 mg/day), both given orally daily for 15 days. The two groups were subsequently divided into three subgroups according to the moment of euthanasia: in the 3rd, 7th and 10th postoperative days. Results:There were no significant changes in weight in both groups. Wound contraction was faster in probiotic group when compared to the controls, resulting in smaller wound area in the 7th postoperative day. As for histological aspects, the overall H&E score was lower in the probiotic group. The probiotic group showed increased fibrosis from 3rd to the 7th postoperative day. The type I collagen production was higher in the probiotic group at the 10th postoperative day, and the type III collagen increased in the 7th. Conclusion:The perioperative use of orally administrated probiotic was associated with a faster reduction of the wound area in rats probably by reducing the inflammatory phase, accelerating the fibrosis process and the deposition of collagen.
Background: Chronic wounds in patients with Diabetes Mellitus often become incurable due to prolonged and excessive production of inflammatory cytokines. The use of probiotics modifies the intestinal microbiota and modulates inflammatory reactions. Aim: To evaluate the influence of perioperative supplementation with probiotics in the cutaneous healing process in diabetic rats. Methods: Forty-six rats were divided into four groups (C3, P3, C10, P10) according to the treatment (P=probiotic or C=control, both orally administered) and day of euthanasia, 3rd or 10th postoperative days. All rats were induced to Diabetes Mellitus 72 h before starting the experiment with alloxan. Supplementation was initiated five days before the incision and maintained until euthanasia. Scalpel incision was guided by a 2x2 cm mold and the wounds were left to heal per second-intention. The wounds were digitally measured. Collagen densitometry was done with Picrosirius Red staining. Histological parameters were analyzed by staining by H&E. Results: The contraction of the wound was faster in the P10 group which resulted in a smaller scar area (p=0.011). There was an increase in type I collagen deposition from the 3rd to the 10th postoperative day in the probiotic groups (p=0.016), which did not occur in the control group (p=0.487). The histological analysis showed a better degree of healing in the P10 group (p=0.005), with fewer polymorphonuclear (p<0.001) and more neovessels (p=0.001). Conclusions: Perioperative supplementation of probiotics stimulates skin wound healing in diabetic rats, possibly due to attenuation of the inflammatory response and increased neovascularization and type I collagen deposition.

This nutrition consensus document is the first to coordinate the efforts of three professional organizations - the Brazilian Association of Nutrition (Asbran), the Brazilian Society of Nephrology (SBN), and the Brazilian Society of Parenteral and Enteral Nutrition (Braspen/SBNPE) - to select terminology and international standardized tools used in nutrition care. Its purpose is to improve the training delivered to nutritionists working with adult patients with chronic kidney disease (CKD). Eleven questions were developed concerning patient screening, care, and nutrition outcome management. The recommendations set out in this document were developed based on international guidelines and papers published in electronic databases such as PubMed, EMBASE(tm), CINHAL, Web of Science, and Cochrane. From a list of internationally standardized terms, twenty nutritionists selected the ones they deemed relevant in clinical practice involving outpatients with CKD. The content validity index (CVI) was calculated with 80% agreement in the answers. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework was used to assess the strength of evidence and recommendations. A total of 107 terms related to Nutrition Assessment and Reassessment, 28 to Diagnosis, nine to Intervention, and 94 to Monitoring and Evaluation were selected. The list of selected terms and identified tools will be used in the development of training programs and the implementation of standardized nutrition terminology for nutritionists working with patients with chronic kidney disease in Brazil.
Introduction: Alzheimer’s disease (AD) is characterized by a progressive and persistent deterioration of the whole cognitive function, which results in an impaired cortical function. Some years ago, the connection between AD and type 2 diabetes has been studied, resulting in the term type 3 diabetes (T3D). Methods: This is a literature review, a search for articles published in the last 5 years in the Medline and PubMed databases was performed, using the descriptor: Alzheimer disease, diabetes, insulin resistance. Results: For analysis, 12 articles were selected, with 10 literature reviews and 2 original studies. Among those who explored the cellular and molecular relationship between AD and insulin resistance, possible pathogenic mechanisms, the role of insulin in the brain, environmental factors linked to AD and dietary interventions to prevent neurodegeneration. Conclusion: The relation between AD and type 2 diabetes is due several mechanisms such as lipid metabolism, insulin metabolism and agents related to its functioning, like the ApoEε4, C-peptide, the glycogen synthase kinase 3β (GSK-3β) and the amyloid-beta (Aβ). It is suggested that several changes, mainly in insulin metabolism, can impair neurocognitive function and trigger AD. Future studies are needed to analyze the context of T3D and find possible treatments that attenuate the AD progression and promote quality of life for the patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
