Clinical Nutrition for the Medical Patient: From Screening to Diagnosis and Start of Nutritional Therapy Abstract. With the demographic increase of elderly, multimorbid patients, the number of those with disease-related malnutrition is also steadily increasing. We now know that malnutrition is a strong and independent risk factor for morbidity, mortality, and poor quality of life. Fortunately, however, several studies have shown that malnutrition screening followed by physiological nutritional therapy to meet individual nutritional goals has a positive impact on the clinical course of medical patients. In this context, Nutritional Risk Screening is suitable as a tool for assessing nutritive risk in hospitalized and ambulatory patients in family practice. Patients at risk for malnutrition should undergo an in-depth clinical assessment in an interdisciplinary team of nutritionists, nurses, and physicians to clarify the etiology of malnutrition and risk factors, and to examine the indication for nutritional therapy. Such nutrition therapy should be individually tailored to the patient's nutritional needs (calorie, protein, and micronutrient requirements), the underlying disease and the patient's preferences. Patients should be closely monitored, and the therapy should be adapted during the disease.

An Update of Medical Nutrition Therapy in Gestational Diabetes Mellitus.

Gestational diabetes mellitus (GDM) is a serious and frequent pregnancy complication that can lead to short and long-term risks for both mother and fetus. Different health organizations proposed different algorithms for the screening, diagnosis, and management of GDM. Medical Nutrition Therapy (MNT), together with physical exercise and frequent self-monitoring, represents the milestone for GDM treatment in order to reduce maternal and fetal complications. The pregnant woman should benefit from her family support and make changes in their lifestyles, changes that, in the end, will be beneficial for the whole family. The aim of this manuscript is to review the literature about the Medical Nutrition Therapy in GDM and its crucial role in GDM management.

Comparison of Micronutrient Intervention Strategies in Ghana and Benin to Cover Micronutrient Needs: Simulation of Bene-Fits and Risks in Women of Reproductive Age.

Overlapping micronutrient interventions might increase the risk of excessive micronutrient intake, with potentially adverse health effects. To evaluate how strategies currently implemented in Benin and Ghana contribute to micronutrient intake in women of reproductive age (WRA), and to assess the risk for excess intakes, scenarios of basic rural and urban diets were built, and different on-going interventions were added. We estimated micronutrient intakes for all different scenarios. Four types of intervention were included in the scenarios: fortification, biofortification, supplementation and use of locally available nutrient-rich foods. Basic diets contributed poorly to daily micronutrient intake in WRA. Fortification of oil and salt were essential to reach daily requirements for vitamin A and iodine, while fortified flour contributed less. Biofortified products could make an important contribution to the coverage of vitamin A needs, while they were not sufficient to cover the needs of WRA. Iron and folic acid supplementation was a major contributor in the intake of iron and folate, but only in pregnant and lactating women. Risk of excess were found for three micronutrients (vitamin A, folic acid and niacin) in specific contexts, with excess only coming from voluntary fortified food, supplementation and the simultaneous overlap of several interventions. Better regulation and control of fortification and targeting of supplementation could avoid excess intakes.

Refeeding syndrome occurs among older adults regardless of refeeding rates: A systematic review.

Refeeding syndrome is a life-threatening clinical disorder that can occur when treating malnutrition. The aim was to examine the current knowledge of refeeding syndrome in patients ≥ 65 + years with special focus on the incidence of hypophosphatemia (HP) in relation to refeeding rate (kcal/kg/day), number of days until the lowest level of phosphate occurs (day of nadir), refeeding rates and adverse events, and death. Specifically, we hypothesized that higher energy provision would cause a higher incidence of HP. A search was conducted in the available databases. Two cohort studies, 1 case control, and a total of 12 case series/case reports, which accounted for 19 individual patient cases, were eligible. The incidence of HP (<0.5 mmol/L) was 15% and 25% in the 2 cohort studies and 4% in the case control study. The mean day of nadir was between days 2 and 3 in the cohort studies, day 11 in the case control study, and day 3 in the cases series/case reports. Importantly, a rapid drop in phosphate occurred receiving both 30 kcal/kg/day and 8 to 10 kcal/kg/day. The cohort studies reported high death rates-26% and 23%-using both 10 and 20 kcal/kg/day, respectively. Adverse events were noted in most all case series/case reports. Clinicians should be aware that HP may occur in up to 25% of older hospitalized adults, and importantly, it occurs even when refeeding cautiously. Hence, electrolytes should be closely monitored, especially between days 2 and 4, which is when the day of nadir occurs most frequently.

The Role of Nutrition During the COVID-19 Pandemic: What We Know.

BACKGROUND: Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) (COVID-19) infection provokes serious clinical consequences, which in many situations need hospitalization of the patient in Intensive Care Unit. Additionally, SARS-COV-2 infection can indirectly cause deaths in aged individuals as well as in patients with co-morbidities. OBJECTIVE: To evaluate the effects of nutrition during the COVID-19 pandemic in both hospitalized patients and the general population. METHODS: Authors searched Medline (PubMed), Web of Science, EMBASE, Cochrane Library, Google, and Institutional websites for medical subheadings terms and free full text referred to "SARS-CoV-2", COVID-19", "nutrition", "immune system", before 31st July 2020. RESULTS: A total of 20 articles describing different nutritional interventions for patients with SARS-- CoV-2 infection focusing on the general population have been included. Of these, 6 studies are dealing with nutritional interventions for patients with SARS-CoV2 infection. The others are focalized on a potential beneficial effect exerted by a Mediterranean diet (MD), related to the supplementation of micronutrients and vitamins. CONCLUSION: A correct lifestyle, including the consumption of nutrients largely present in MD, may be beneficial for preventing or improving prognosis in the SARS-CoV-2 infection.

Mortality associated with new risk classification of developing refeeding syndrome in critically ill patients: A cohort study.

BACKGROUND & AIMS: Although refeeding syndrome (RFS) has been recognized as a potentially fatal metabolic complication, the definition of RFS has remained unclear. Recently, European researchers suggested an evidence-based and consensus-supported algorithm that consisted of a new RFS risk classification and treatment strategies for medical inpatients. The classification was based on the National Institute for Health and Clinical Excellence (NICE) criteria for patients at risk of developing RFS. In this study, we aimed to investigate the frequency of each applied new risk group and the association between the new classification and mortality in critically ill patients. METHODS: This cohort study was conducted at a Japanese metropolitan tertiary-care university hospital from December 2016 to December 2018. We included critically ill adult patients who were admitted to the intensive care unit (ICU) via the emergency department and who stayed in the ICU for 24 h or longer. We applied the new risk classification based on the NICE RFS risk factors on ICU admission. The main exposure was risk classification of RFS: no risk, low risk, high risk, or very high risk. The primary outcome was in-hospital mortality censored at day 30 after ICU admission. We performed a multivariable analysis using Cox proportional hazard regression. RESULTS: We analyzed 542 patients who met the eligibility criteria. The prevalence of the four RFS risk classification groups was 25.8% for no risk, 25.7% for low risk, 46.5% for high risk, and 2.0% for very high risk. The 30-day mortality was 5.0%, 7.2%, 16.3%, and 27.3%, respectively (log-rank trend test: p < 0.001). In the multivariable Cox regression, adjusted hazard ratios with no risk group as a reference were 1.28 (95% CI 0.48-3.38) for low risk, 2.81 (95% CI 1.24-6.35) for high risk, and 3.17 (95% CI 0.78-12.91) for very high risk. CONCLUSIONS: Approximately half the critically ill patients were categorized as high or very high risk based on the new risk classification. Furthermore, as the risk categories progressed, the 30-day in-hospital mortality increased. Early recognition of patients at risk of developing RFS may improve patient outcomes through timely and optimal nutritional treatment.

Biomarkers in critical care nutrition.

The goal of nutrition support is to provide the substrates required to match the bioenergetic needs of the patient and promote the net synthesis of macromolecules required for the preservation of lean mass, organ function, and immunity. Contemporary observational studies have exposed the pervasive undernutrition of critically ill patients and its association with adverse clinical outcomes. The intuitive hypothesis is that optimization of nutrition delivery should improve ICU clinical outcomes. It is therefore surprising that multiple large randomized controlled trials have failed to demonstrate the clinical benefit of restoring or maximizing nutrient intake. This may be in part due to the absence of biological markers that identify patients who are most likely to benefit from nutrition interventions and that monitor the effects of nutrition support. Here, we discuss the need for practical risk stratification tools in critical care nutrition, a proposed rationale for targeted biomarker development, and potential approaches that can be adopted for biomarker identification and validation in the field.

Heterogeneity of nutrition care procedures in nutrition guidelines for cancer patients.

OBJECTIVES: The aim of this study was to systematically assess the nutrition care procedures in nutrition guidelines for cancer patients and identify gaps limiting evidence-based practise. METHODS: A systematic search of databases and websites was conducted to identify nutrition guidelines for cancer patients. The quality of the eligible guidelines was evaluated by using the Appraisal of Guidelines for Research and Evaluation (AGREE II). The Measurement Scale of Rate of Agreement (MSRA) was used to assess the scientific agreement of formulated recommendations for nutrition care procedures in the guidelines (2017-2019), and evidence supporting these recommendations was extracted and analysed. RESULTS: Seventeen nutrition guidelines for cancer patients were identified. Only European Society for Clinical Nutrition and Metabolism (ESPEN) and Australian guidelines have a total quality score of more than 60%, which is worthy of clinical recommendation. Twelve guidelines (2017-2019) were included to further analyse the heterogeneity and causes of nutrition care procedures, and we found that the content and tools of nutrition screening and assessment, the application of immune nutrients, and the selection of nutritional support pathways were heterogeneous. The main reasons for the heterogeneity of nutrition care procedures were insufficient attention to nutrition risk screening, differences in recommendations for nutrition assessment, immune nutrients and nutritional support, unreasonable citation of screening and assessment evidence, preference of developers, and lack of evidence of high-quality research on energy and nitrogen demand. In addition, the fairness and propensity of the guidelines for the selection of evidence for different cancer patients are also potential reasons for the heterogeneity of nutritional care procedures. CONCLUSIONS: The quality of the nutrition guidelines for cancer patients was highly variable. The nutrition care procedures were heterogeneous among the different guidelines in the last 3 years. Specific improvement of the factors leading to the heterogeneity of nutrition care procedures will be a reasonable and effective way for developers to upgrade the nutrition care procedures in the guidelines for cancer patients.

Infection rate among nutritional therapies for acute pancreatitis: A systematic review with network meta-analysis of randomized controlled trials.

BACKGROUND: Infection in acute pancreatitis (AP) is associated with nutritional therapies including naso-gastric (NG), naso-jejunal (NJ), and total parenteral nutrition (TPN). To examine infections among NG, NJ, TPN, and no nutritional support (NNS) in treating patients with AP. METHODS: The investigators completed comprehensive search in the Cochrane library, EMBASE, PubMed, Web of Science, and ClinicalTrials.gov without restriction on language and publication date before January 21, 2019. They also searched the reference lists of relevant studies for randomized controlled trials (RCTs) comparing NG, NJ, TPN, and NNS among patients with AP. Quantitative synthesis was conducted in a contrast-based network meta-analysis. To clarify effects, a network meta-analysis was conducted to calculate the surface under the cumulative ranking curve (SUCRA). Beside of overall infections, the event rates of infected pancreatic necrosis, bacteremia, line infection, pneumonia, urinary tract infection, and other types of infections were measured. RESULTS: The network meta-analysis of 16 RCTs showed that NJ had significantly lower overall infection rates compared with TPN (risk ratio: 0.59; 95% confidence interval: 0.38, 0.90); and NG had a larger effect size and higher rank probability compared with NJ, TPN, and NNS (mean rank = 1.7; SUCRA = 75.8). TPN was the least preferred (mean rank = 3.2; SUCRA = 26.6). CONCLUSIONS: NG and NJ may be preferred therapies for treating patients with AP. Clinicians may consider NG as a first-line treatment for patients with AP (including severe AP) and even in patients receiving prophylactic antibiotics. In addition, we found that NNS should be avoided when treating patients with severe AP.

Fully closed-loop insulin delivery in inpatients receiving nutritional support: a two-centre, open-label, randomised controlled trial.

BACKGROUND: Glucose management is challenging in patients who require nutritional support in hospital. We aimed to assess whether fully closed-loop insulin delivery would improve glycaemic control compared with conventional subcutaneous insulin therapy in inpatients receiving enteral or parenteral nutrition or both. METHODS: We did a two-centre (UK and Switzerland), open-label, randomised controlled trial in adult inpatients receiving enteral or parenteral nutrition (or both) who required subcutaneous insulin therapy. Patients recruited from non-critical care surgical and medical wards were randomly assigned (1:1) using a computer-generated minimisation schedule (stratified by type of nutritional support [parenteral nutrition on or off] and pre-study total daily insulin dose [<50 or ≥50 units]) to receive fully closed-loop insulin delivery with faster-acting insulin aspart (closed-loop group) or conventional subcutaneous insulin therapy (control group) given in accordance with local clinical practice. Continuous glucose monitoring in the control group was masked to patients, ward staff, and investigators. Patients were followed up for a maximum of 15 days or until hospital discharge. The primary endpoint was the proportion of time that sensor glucose concentration was in target range (5·6-10·0 mmol/L), assessed in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT01774565. FINDINGS: Between Feb 8, 2018, and Sept 21, 2018, 90 patients were assessed for eligibility, of whom 43 were enrolled and randomly assigned to the closed-loop group (n=21) or the control group (n=22). The proportion of time that sensor glucose was in the target range was 68·4% [SD 15·5] in the closed-loop group and 36·4% [26·6] in the control group (difference 32·0 percentage points [95% CI 18·5-45·5; p<0·0001]). One serious adverse event occurred in each group (one cardiac arrest in the control group and one episode of acute respiratory failure in the closed-loop group), both of which were unrelated to study interventions. There were no adverse events related to study interventions in either group. No episodes of severe hypoglycaemia or hyperglycaemia with ketonaemia occurred in either study group. INTERPRETATION: Closed-loop insulin delivery is an effective treatment option to improve glycaemic control in patients receiving nutritional support in hospital.

Gut rest strategy and trophic feeding in the acute phase of critical illness with acute gastrointestinal injury.

Critically ill patients frequently suffer from gastrointestinal dysfunction as the intestine is a vulnerable organ. In critically ill patients who require nutritional support, the current guidelines recommend the use of enteral nutrition within 24-48 h and advancing towards optimal nutritional goals over the next 48-72 h; however, this may be contraindicated in patients with acute gastrointestinal injury because overuse of the gut in the acute phase of critical illness may have an adverse effect on the prognosis. We propose that trophic feeding after 72 h, as a partial gut rest strategy, should be provided to critically ill patients during the acute phase of illness as an organ-protective strategy, especially for those with acute gastrointestinal injury.

Impact of an oral nutrition protocol in patients treated with elective radical cystectomy: a long term follow-up.

Background After radical cystectomy, delayed return of bowel function is relatively common. Although studies investigating on the best modality for delivering nutritional support to this patient group are limited, parenteral nutrition was standard of care in those patients at the urological ward of the University Hospitals Leuven. In 2015, we published the findings from our study conducted in patients undergoing elective regular radical cystectomy at the urological ward of the University Hospitals Leuven comparing the length of hospital stay in patients with early postoperative parenteral nutrition (n = 48) versus an immediate oral nutrition protocol (n = 46). It was demonstrated that the implementation of an oral nutrition protocol was associated with a significant reduced length of hospital stay (median [IQR] of 18 [15-22] to 14 [13-18] days (p < 0.001)). The sample size was however too small to investigate the impact of the oral nutrition protocol on the incidence of catheter-related bloodstream infection, a common parenteral nutrition related complication. Objective To investigate the long term impact of an oral nutrition protocol on the incidence of catheter-related bloodstream infection, duration of catheterization and the length of hospital stay. Method Retrospectively, before (parenteral nutrition group) and after the implementation of the oral nutrition protocol (since March 10th 2010), two cohorts of 549 patients who underwent an elective regular radical cystectomy were included. The incidence of a catheter-related bloodstream infection and the length of stay were compared. A central venous catheter was present in every patient, which is standard of care. Results Catheter-related bloodstream infection was reduced from 22 (4%) to 10 (1.8%) (p = 0.031). The median duration of catheterization was 10 [7-13] days for the parenteral nutrition versus 7 [7-7] days for the oral nutrition group (p < 0.001). The median length of stay between both groups, 20 [17-25] before versus 17 [14-21] days after the implementation of the oral nutrition protocol, also differed significantly (p < 0.001). Implementing the oral nutrition protocol resulted in a parenteral nutrition associated cost saving of €470 per patient. Conclusion This large follow-up study showed that the oral nutrition protocol is associated with a reduction in catheter-related bloodstream infection. Besides, postponing parenteral nutrition in favour of oral nutrition enhances recovery.

Extrauterine Growth Restriction in Low Birth Weight Infants.

Extrauterine growth restriction (EUGR) affects a significant number of very low birth weight (VLBW) infants and has the potential to impact neurodevelopmental outcome as well as other aspects of long-term health. More aggressive nutritional approaches have reduced the incidence of postnatal growth failure but many questions remain about the expected rate of growth for very preterm infants, the best ways to measure growth velocity, and the optimal approaches to supporting growth. This article examines some of the outstanding issues regarding postnatal growth failure and summarizes current practice recommendations.

Effects of Early Initiation of Solid Versus Liquid Diet after Endoscopic Submucosal Dissection on Quality of Life and Postoperative Outcomes: A Prospective Pilot Randomized Controlled Trial.

BACKGROUND/AIMS: Feeding recommendations after endoscopic submucosal dissection (ESD) for gastric neoplasms are not established and based on clinical experience. METHODS: This was a prospective pilot randomized controlled trial. Patients undergoing ESD for gastric neoplasms were randomly assigned to solid (n = 50) or liquid diet (n = 50) groups. Beginning the day after hemostasis confirmation until discharge, the solid diet group started on a diet of rice porridge, whereas the liquid diet group started on a liquid diet, with gradual transition to solid food. The primary endpoint was delayed bleeding rate. The secondary endpoints were quality of life (QOL), ulcer-stage, hospital fees, and post-ESD symptoms. RESULTS: Delayed bleeding occurred in the solid diet group (2%) but not in the liquid diet group. The QOL evaluation using European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-STO22 showed better score in the solid diet group. The patients who felt dietary restriction at discharge was of a larger number in the liquid diet group (p = 0.019). More patients experienced appetite loss (p = 0.038), constipation (p = 0.022), and dietary restriction (p = 0.037) in the liquid diet group during hospitalization. The other endpoints were equivalent between the groups. CONCLUSION: Early initiation of solid foods after ESD is feasible and associated with higher QOL, potentially rendering conventional liquid diets unnecessary, although additional studies are needed (Trial registration number: UMIN000013297).

Eventos adversos em terapia nutricional: percepção dos profissionais da equipe multiprofissional / Adverse events in Nutritional Therapy: professionals perception of the multi-professional team

Introdução: A terapia nutricional é considerada de alta complexidade, cuja utilização ocorreu de forma crescente graças às boas práticas assistenciais e ao aprimoramento tecnológico. Apesar dos avanços, a efetividade da terapia poderá ser comprometida pela presença de eventos adversos. Objetivo: Verificar a percepção dos profissionais das Equipes Multiprofissionais de Terapia Nutricional sobre os eventos adversos nesta área e seu manejo a nível nacional. Método: Pesquisa prospectiva de abordagem mista, realizada de setembro de 2017 a janeiro de 2018, em duas fases: a primeira, quantitativa, por amostra de conveniência com a caracterização da população e manejo do evento adverso, utilizando a escala Likert; e a segunda, qualitativa, com os cinquenta primeiros respondentes para apreender a percepção e o manejo dos eventos adversos. A coleta de dados ocorreu por meio de entrevista com profissionais que atuam em Equipes Multiprofissionais de Terapia Nutricional e atenderam aos critérios de inclusão. Para análise, na fase I, foi realizado o cálculo de comparação entre a concordância de cada item e utilizado o teste não paramétrico de Mann-Whitney e, para comparação entre categorias profissionais, o teste Kruskal-Wallis, além do teste de hipótese com nível de significância de 5%. Na fase II, os discursos foram analisados segundo Bardin, tendo como referenciais a Teoria do Erro Humano e a Teoria da Vulnerabilidade e, ainda, utilizou-se o software Análise Lexical por Contexto de um Conjunto de Segmentos de Texto - ALCESTE. Resultados: Participaram 120 profissionais, 57,5% pertenciam à região Sudeste, 80,8% do sexo feminino, 33,3% enfermeiros, 29,2% nutricionistas, 22,5% médicos, 10,8% farmacêuticos, 2,5% fonoaudiólogos e 1,7% fisioterapeutas. A idade variou de 25 a 67 anos (média de 41 anos), o tempo de formação profissional de dezessete anos (± 10), a média geral de atuação de 11,4 anos (± 8,61) e o tempo de atuação nas equipes de 6,4 anos (± 7,42). Quanto à formação em terapia nutricional, 33,3% possuíam título de especialista e 68,3% tinham curso de pós-graduação relacionada. Os hospitais em que atuavam eram privados filantrópicos em 55,8%, o número médio de leitos era de 320,3, a acreditação estava presente em 58,3% e as equipes eram próprias em 95,8%. Na nutrição enteral, a apresentação era de 61,7% para o sistema fechado, 67,5% a pronta para uso e a administração era contínua em 64,2%. Na nutrição parenteral, 45,8% utilizavam a formulação mista (individualizada e industrializada), 87,5% tinham o preparo terceirizado e para 90,8% a administração era de forma contínua. O uso de bombas de infusão para dieta enteral foi de 97,5% e na nutrição parenteral de 99,2%. Pela análise dos discursos, utilizando-se a Teoria da Vulnerabilidade, pudemos aprender, na dimensão Individual, as categorias centrais voltadas ao paciente, acesso (vias de administração), prescrição e principalmente administração das soluções. Já na dimensão Programática, foram encontrados os protocolos de administração da terapia nutricional e os programas de treinamento. Na dimensão Social, as normas institucionais e diretrizes, não focando as Portarias Ministeriais, cujo conteúdo facilita a atuação dos profissionais. Conclusão: Este estudo possibilitou reconhecer que não há diferenças na realidade das equipes multiprofissionais no Brasil, assim como no perfil dos profissionais e a ocorrência dos eventos adversos. A Teoria da Vulnerabilidade apontou o predomínio da dimensão Individual, em que as falhas recorreram sobre os indivíduos, principalmente, para a equipe de Enfermagem, e as fragilidades das dimensões Programática e Social mostram também a necessidade de ampliar e fortalecer programas de treinamento e estabelecer protocolos que auxiliem na atuação dos profissionais da Equipe Multiprofissional de Terapia Nutricional e prevenir os eventos adversos

Introduction: Nutritional therapy is considered highly complex, which has been increasingly used thanks to good care practices and technological improvement. Despite all the advances, the effectiveness of therapy may be compromised by adverse events. Objective: To verify the professionals' perception of the Multi-professional Nutrition Therapy Teams on adverse events and their management nationwide. Methods: A prospective, mixed approach survey performed from September 2017 to January 2018 in two phases: the first, quantitative, by convenience sample with population characterization and adverse event management, using the Likert scale; and the second, qualitative, with the first fifty respondents to achieve the perception and management of adverse events. Data were collected through interviews with professionals who work in Multi-professional Nutrition Therapy Teams and fit in inclusion criteria. For analysis, in phase I, the comparison between the agreement of each item was performed and the non-parametric Mann-Whitney test was applied and, for comparison between professional categories, the Kruskal-Wallis test, in addition to the hypothesis test with significance level by 5%. In phase II, the speeches were analyzed according to Bardin, with reference the Human Error Theory and Vulnerability Theory and, also, lexical analysis by context of text segments set software ALCESTE was applied. Results: About 120 professionals participated, 57.5% from the Southeast region, 80.8% were female, 33.3% nurses, 29.2% nutritionists, 22.5% doctors, 10.8% pharmacists, 2.5% speech therapists and 1.7% physiotherapists. The age ranged from 25 to 67 years (mean of 41 years), the professional training time was seventeen years (± 10), the overall mean performance was 11.4 years (± 8.61) and the team performance was 6.4 years (± 7.42). As for training in nutritional therapy, 33.3% had a specialist degree and 68.3% had a related postgraduate course. The hospitals where they worked at were private philanthropic in 55.8%, the average number of beds was 320.3, the accreditation was in 58.3% and they have their own team in 95.8%. In enteral nutrition, the presentation was 61.7% for closed system, 67.5% ready for use and administration was continuous in 64.2%. In parenteral nutrition, 45.8% used the mixed formulation (individualized and industrialized), 87.5% had outsourced preparation and 90.8% were administered continuously. The use of infusion pumps for enteral diet was 97.5% and in parenteral nutrition 99.2%. Through the discourses analysis, using the Vulnerability Theory, we had learned, in Individual dimension, the central categories focused on the patient, access (routes of administration), prescription and mainly solutions administration. In Programmatic dimension, the TN administration protocols and the Training Programs were found. In Social dimension, the institutional norms and directives, not focusing on Ministerial Ordinances, whose content promotes professionals' performance. Conclusion: This study enables to recognize that there are no differences in the reality of multi-professional teams in Brazil, as well as in the professionals profile and adverse event occurrence. The Vulnerability Theory pointed to the predominance of Individual dimension, in which the flaws resorted to individuals, mainly to the nursing team and the frailties of Programmatic and Social dimensions, also shows the necessity to expand and to strengthen training programs and establish protocols that assist the professionals practice of the Multi-professional Team of Nutritional Therapy and to prevent adverse events

Copper deficiency anemia: review article.

Copper is a crucial micronutrient needed by animals and humans for proper organ function and metabolic processes such as hemoglobin synthesis, as a neurotransmitter, for iron oxidation, cellular respiration, and antioxidant defense peptide amidation, and in the formation of pigments and connective tissue. Multiple factors, either hereditary or acquired, contribute to the increase in copper deficiency seen clinically over the past decades. The uptake of dietary copper into intestinal cells is via the Ctr1 transporter, located at the apical membrane aspect of intestinal cells and in most tissues. Copper is excreted from enterocytes into the blood via the Cu-ATPase, ATP7A, by trafficking the transporter towards the basolateral membrane. Zinc is another important micronutrient in animals and humans. Although zinc absorption may occur by direct interaction with the Ctr1 transporter, its absorption is slightly different. Copper deficiency affects physiologic systems such as bone marrow hematopoiesis, optic nerve function, and the nervous system in general. Detailed pathophysiology and its related diseases are explained in this manuscript. Diagnosis is made by measuring serum copper, serum ceruloplasmin, and 24-h urine copper levels. Copper deficiency anemia is treated with oral or intravenous copper replacement in the form of copper gluconate, copper sulfate, or copper chloride. Hematological manifestations are fully reversible with copper supplementation over a 4- to 12-week period. However, neurological manifestations are only partially reversible with copper supplementation.

Feeding During Phases of Altered Mitochondrial Activity: A Theory.

Decisions surrounding the timing and dosing of nutrition support are made for thousands of ICU patients daily and yet remain a topic of controversy. Nutrition support designed to replenish resting energy expenditure (REE) early in critical illness has led to worse clinical outcomes in at least three recent prospective randomized clinical trials. Producing sufficient energy from nutrient substrates requires use of the mitochondrial electron transport chain (ETC). This process is functionally linked to the creation of a tightly regulated series of chemical messengers known as reactive oxygen species (ROS). In health, ROS are kept at low levels by a system of mitochondrial/cellular enzymes and antioxidants, allowing ROS to act as a signal for the redox health of the cell. In inflammatory conditions, however, this system is altered, leading to changes in the physiologic function of the ETC such that its usage produces greater ROS per unit of substrate. This increased ROS is capable of deactivating antioxidant systems, as well as activating further ROS-producing pathways and stimulating localized inflammatory activity. We propose that exacerbation of this process at this time by the forced influx of exogenously acquired nutrient substrates leads to mitochondrial damage, amplified ROS production, increased inflammation, decreased ATP-productive capacity, and, eventually, the death of the cell by either apoptosis or necrosis. Knowledge of this process is vital to determining the safe dosing and timing of nutrition support in the ICU. It is possible that the physiologic cost of meeting the REE under these conditions of mitochondrial stress may simply be too high.

Refeeding syndrome is a life-threatening complication that may occur after initiation of nutritional therapy in malnourished patients, as well as after periods of fasting and hunger. Refeeding syndrome can be effectively prevented and treated if its risk factors and pathophysiology are known. The initial measurement of thiamine level and serum electrolytes, including phosphate and magnesium, their supplementation if necessary, and a slow increase in nutritional intake along with close monitoring of serum electrolytes play an important role. Since refeeding syndrome is not well known and the symptoms can be extremely heterogeneous, this complication is poorly recognized, especially against the background of severe disease and multimorbidity. This overview aims to summarize the current knowledge and increase awareness about refeeding syndrome.
