Changes in the Gut Microbiota after the Use of Herbal Medicines in Overweight and Obese Individuals: A Systematic Review.

BACKGROUND: Herbal medicine is a low-cost treatment and has been increasingly applied in obesity treatment. Gut microbiota (GM) is strongly associated with obesity pathogenesis. METHODS: We conducted a systematic review guided by the question: "Does the use of herbal medicine change the GM composition in obese individuals?" Randomized clinical trials with obese individuals assessing the effects of herbal medicine intervention in GM were retrieved from the Medline, Embase, Scopus, Web of Science, and Cochrane Library databases, including the Cochrane Controlled Trials Register. Two reviewers independently extracted data using standardized piloted data extraction forms and assessed the study-level risk of bias using an Excel template of the Cochrane "Risk of bias" tool 2-RoB 2. RESULTS: We identified 1094 articles in the databases. After removing duplicates and reading the title and abstract, 14 publications were fully evaluated, of which seven publications from six studies were considered eligible. The herbs analyzed were Moringa oleifera, Punica granatum, Scutellaria baicalensis, Schisandra chinensis, W-LHIT and WCBE. The analysis showed that Schisandra chinensis and Scutellaria baicalensis had significant effects on weight loss herbal intervention therapy composed by five Chinese herbal medicines Ganoderma lucidum, Coptis chinensis, Astragalus membranaceus, Nelumbo nucifera gaertn, and Fructus aurantii (W-LHIT) and white common bean extract (WCBE) on GM, but no significant changes in anthropometry and laboratory biomarkers. CONCLUSIONS: Herbal medicine modulates GM and is associated with increased genera in obese individuals.

Effect of a parenteral fish-oil-containing lipid emulsion on liver lipid perioxidation and antioxidative defenses in Lewis rats.

BACKGROUND: Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), naturally abundant in fish oil (FO), are known for their anti-inflammatory and potential antioxidant properties. The aim in this article is to evaluate the effect of the infusion of a parenteral FO-containing lipid emulsion on markers of liver lipid peroxidation and oxidative stress in rats undergoing central venous catheterization (CVC). METHODS: After 5-day acclimatization, adult Lewis rats (n = 42) receiving a 20-g/day AIN-93M oral diet were randomly subdivided into four groups: (1) basal control (BC) (n = 6), without CVC or LE infusion; (2) SHAM (n = 12), with CVC but without LE infusion; (3) soybean oil (SO)/medium-chain triglyceride (MCT) (n = 12), with CVC and receiving LE without FO (4.3 g/kg fat); and (4) SO/MCT/FO (n = 12), with CVC and receiving LE containing 10% FO (4.3 g/kg fat). Animals from the BC group were euthanized immediately after acclimatization. The remaining groups of animals were euthanized after 48 or 72 h of surgical follow-up to assess profiles of liver and plasma fatty acids by gas chromatography, liver gene transcription factor Nrf2, F2-isoprostane lipid peroxidation biomarker, and the antioxidant enzymes glutathione peroxidase (GPx), superoxide dismutase (SOD), and catalase (CAT) by enzyme-linked immunosorbent assay. R program (version 3.2.2) was utilized for data analysis. RESULTS: Compared with the other groups, liver EPA and DHA levels were higher in the SO/MCT/FO group, which also showed the highest liver Nrf2, GPx, SOD, and CAT levels and lower liver F2-isoprostane (P < 0.05). CONCLUSION: Experimental delivery of FO via EPA and DHA sources in a parenteral LE was associated with a liver antioxidant effect.

Gastrointestinal and sensory manifestations, nutrition management, and energy-protein intake in hospitalized patients with COVID-19.

BACKGROUND: Gastrointestinal and sensory manifestations (GSMs) of coronavirus disease 2019 (COVID-19) may affect food intake, resulting in malnutrition and poor outcomes. We characterized the impact of GSMs and oral nutrition supplementation on energy-protein intake (EPI) and hospital discharge in adult patients with COVID-19. METHODS: Patients from two hospitals were enrolled (n = 357). We recorded the presence and type of GSM at admission, estimated energy requirements (EER) and the EPI based on regular food intake (plate diagram sheets) during hospital stays. Patients not achieving 60% of their EER from food over 2 consecutive days received oral nutrition supplementation (ONS) with a high-energy-protein oral drink. RESULTS: Most patients (63.6%) presented with GSMs at admission. Anorexia was the most common manifestation (44%). Patients with anorexia or more than one GSMs were more likely to not achieve 60% EER on the first day of follow-up and to require the ONS intervention (P ≤ 0.050). Prevalence of at least one GSM was higher in patients who did not achieve hospital discharge than in patients who achieved it (74.2% vs 54.6%, P = 0.038). The patients requiring ONS (26.9%) demonstrated good adherence to the intervention (79.3%), achieved their EER during 95.7% of the supplementation time, and presented with hospital discharge rates similar to patients not requiring ONS (92.2% vs 91.9%, respectively; P = 1.000). CONCLUSIONS: GSM were prevalent in COVID-19 and it impaired EER attendance and patient recovery. ONS was well-tolerated, aided EER attendance, and potentially facilitated hospital discharge.

Gastrointestinal genetic reprogramming of vitamin A metabolic pathways in response of Roux-en-Y gastric bypass.

Roux-en-Y gastric bypass (RYGB) is one of the most performed bariatric surgical techniques. However, RYGB commonly results, as side effects, in nutritional deficiencies. This study aimed to examine changes in the expression of vitamin A pathway encoding genes in the gastrointestinal tract (GI) and to evaluate the potential mechanisms associated with hypovitaminosis A after RYGB. Intestinal biopsies were obtained through double-balloon endoscopy in 20 women with obesity (age 46.9±6.2 years; body mass index [BMI] 46.5±5.3 kg/m2 [mean±SD]) before and three months after RYGB (BMI, 38.2±4.2 kg/m2). Intestinal mucosal gene microarray analyses were performed in samples using a Human GeneChip 1.0 ST array (Affymetrix). Vitamin A intake was assessed from 7-day food records and serum retinol levels were evaluated by electrochemiluminescence immunoassay. Our results showed the following genes with significant downregulation (p≤0.05): LIPF (-0.60), NPC1L1 (-0.71), BCO1 (-0.45), and RBP4 (-0.13) in duodenum; CD36 (-0.33), and ISX (-0.43) in jejunum and BCO1 (-0.29) in ileum. No significant changes in vitamin A intake were found (784±694 retinol equivalents [RE] pre-operative vs. 809±753 RE post-operative [mean±SD]). Although patients were routinely supplemented with 3500 international units IU/day (equivalent to 1050 µg RE/day) of oral retinol palmitate, serum concentrations were lower in the post-operative when compared to pre-operative period (0.35±0.14 µg/L vs. 0.52±0.33 µg/L, respectively - P=0.07), both within the normal range. After RYGB, the simultaneous change in expression of GI genes, may impair carotenoid metabolism in the enterocytes, formation of nascent chylomicrons and transport of retinol, resulting in lower availability of vitamin A.

ESPEN practical guideline: Clinical nutrition in surgery.

Early oral feeding is the preferred mode of nutrition for surgical patients. Avoidance of any nutritional therapy bears the risk of underfeeding during the postoperative course after major surgery. Considering that malnutrition and underfeeding are risk factors for postoperative complications, early enteral feeding is especially relevant for any surgical patient at nutritional risk, especially for those undergoing upper gastrointestinal surgery. The focus of this guideline is to cover both nutritional aspects of the Enhanced Recovery After Surgery (ERAS) concept and the special nutritional needs of patients undergoing major surgery, e.g. for cancer, and of those developing severe complications despite best perioperative care. From a metabolic and nutritional point of view, the key aspects of perioperative care include the integration of nutrition into the overall management of the patient, avoidance of long periods of preoperative fasting, re-establishment of oral feeding as early as possible after surgery, the start of nutritional therapy immediately if a nutritional risk becomes apparent, metabolic control e.g. of blood glucose, reduction of factors which exacerbate stress-related catabolism or impaired gastrointestinal function, minimized time on paralytic agents for ventilator management in the postoperative period, and early mobilization to facilitate protein synthesis and muscle function.

Nutritional guidance, monitoring, and supplementation before and after bariatric surgery - Are we doing this correctly?

INTRODUCTION: Background and aims: minimizing nutritional depletions after a Roux-en-Y gastric bypass (RYGB) may improve clinical results in the treatment of obesity. We evaluated nutritional aspects of obese women undergoing RYGB at a reference university hospital with a department specialized in bariatric surgery. Method: based on the Dietary Reference Intakes developed by the Food and Nutrition Council, Institute of Medicine, and the guidelines issued by the American Society for Metabolic and Bariatric Surgery, we assessed the quantitative and qualitative adequacy of nutritional intake, supplementation, and biochemical monitoring of 20 women both before and 3 and 12 months after a RYGB. Data on nutritional intake was obtained by applying different food surveys, quantitatively interpreted by the Virtual Nutri Plus® software and using reference nutritional databases. Results: nutritional intake deficits were already found before the RYGB (p ≤ 0.05). These worsened postoperatively (p ≤ 0.05), a period also marked by a qualitatively poor diet. The nutritional supplementation prescribed did not fully achieve the reference recommendations, and was poorly complied with by patients. Furthermore, nutritional monitoring was not carried out in all patients, recommended biochemical markers were not screened, and vitamin D depletions occurred. Conclusion: our data suggest that institutions specialized in bariatric patient care may not be adequately adhering to well known guidelines, or applying efficient strategies to improve compliance.

INTRODUCCIÓN: Antecedentes y objetivos: minimizar el deterioro nutricional después del baipás gástrico en Y de Roux (BGYR) puede mejorar los resultados clínicos en el tratamiento de la obesidad. Se evaluaron aspectos nutricionales de mujeres obesas sometidas a BGYR en un hospital universitario de referencia con servicio especializado de cirugía bariátrica. Método: con base en la Ingesta Dietética de Referencia desarrollada por el Consejo de Alimentos y Nutrición del Instituto de Medicina, y las directrices de la Sociedad Estadounidense de Cirugía Bariátrica y Metabólica, evaluamos la adecuación cuantitativa y cualitativa de la ingesta nutricional, la suplementación y el seguimiento bioquímico de 20 mujeres tanto antes como 3 y 12 meses después de un BGYR. Los datos de la ingesta nutricional se obtuvieron mediante la aplicación de diferentes encuestas alimentarias, interpretadas cuantitativamente por el software Virtual Nutri Plus® y utilizando bases de datos nutricionales de referencia. Resultados: se encontraron déficits de ingesta nutricional antes del BGYR (p < 0,05). Estos empeoraron en el postoperatorio (p < 0,05), período también marcado por una mala alimentación cualitativa. La suplementación nutricional prescrita no cumplió plenamente con las recomendaciones de referencia y no fue bien cumplida por los pacientes. Además, la monitorización nutricional no se aplicó en todos los pacientes y no se examinaron todos los marcadores bioquímicos recomendados, hallándose depleciones de vitamina D. Conclusión: nuestros datos sugieren que las instituciones especializadas en la atención de pacientes bariátricos podrían no estar siguiendo adecuadamente las pautas recomendadas, ni aplicando estrategias eficientes para mejorar su cumplimiento.

Parenteral fish oil: An adjuvant pharmacotherapy for coronavirus disease 2019?

The new coronavirus associated with severe acute respiratory syndrome (SARS-CoV-2), surprisingly, does not affect only the lungs. The severe response to SARS-CoV-2 appears to include a "cytokine storm," which indicates a state of hyperinflammation and subsequent dysfunction of multiple organs and tissues in the most severe cases. This could be the reason why populations at the highest risk for death from the SARS-CoV-2 infection-induced disease (coronavirus disease 2019 [COVID-19]) are those suffering from chronic low-grade inflammation, but prone to hyperinflammation. This includes individuals of advanced age and those with obesity, type 2 diabetes, hypertension, and metabolic syndrome. Inflammation resolution is strongly dependent on lipid mediators, the specialized pro-resolution mediators (SPMs). ω-3 polyunsaturated fatty acids (ω-3 PUFAs) are precursors of very potent SPMs, including resolvins, protectins, and maresins. Additionally, they are associated with a less aggressive inflammatory initiation, after competing with ω-6 fatty acids for eicosanoid synthesis. Therefore, it makes sense to consider the use of ω-3 PUFAs for clinical management of COVID-19 patients. ω-3 PUFAs may be given by oral, enteral, or parenteral routes; however, the parenteral route favors faster incorporation into plasma phospholipids, blood cells, and tissues. Here, we discuss these aspects to propose the parenteral infusion of ω-3 PUFAs as adjuvant immunopharmacotherapy for hospitalized patients with COVID-19.

Summary of Proceedings and Expert Consensus Statements From the International Summit "Lipids in Parenteral Nutrition".

BACKGROUND: The 2018 Lipids in Parenteral Nutrition summit involved a panel of experts in clinical nutrition, lipid metabolism, and pharmacology, to assess the current state of knowledge and develop expert consensus statements regarding the use of intravenous lipid emulsions in various patient populations and clinical settings. The main purpose of the consensus statements is to assist healthcare professionals by providing practical guidance on common clinical questions related to the provision of lipid emulsions as part of parenteral nutrition (PN). METHODS: The summit was designed to allow interactive discussion and consensus development. The resulting consensus statements represent the collective opinion of the members of the expert panel, which was informed and supported by scientific evidence and clinical experience. RESULTS: The current article summarizes the key discussion topics from the summit and provides a set of consensus statements designed to complement existing evidence-based guidelines. Lipid emulsions are a major component of PN, serving as a condensed source of energy and essential fatty acids. In addition, lipids modulate a variety of biologic functions, including inflammatory and immune responses, coagulation, and cell signaling. A growing body of evidence suggests that lipid emulsions containing ω-3 fatty acids from fish oil confer important clinical benefits via suppression of inflammatory mediators and activation of pathways involved in the resolution of inflammation. CONCLUSIONS: This article provides a set of expert consensus statements to complement formal PN guideline recommendations.

Lipids in Parenteral Nutrition: Biological Aspects.

Lipid emulsions are an integral part of parenteral nutrition, and traditionally have been regarded as an energy-dense source of calories and essential fatty acids. For many years, lipids used in parenteral nutrition have been based on vegetable oils (eg, soybean-oil emulsions). However, soybean-oil emulsions may not have an optimal fatty-acid composition under some circumstances when used as the only lipid source, as soybean oil is particularly abundant in the ω-6 polyunsaturated fatty acid (PUFA), linoleic acid. Hence, a progressive series of more complex lipid emulsions have been introduced, typically combining soybean oil with 1 or more alternative oils, such as medium-chain triglycerides (MCTs) and/or olive oil and/or fish oil. The wide range of lipid emulsions now available for parenteral nutrition offers opportunities to alter the supply of different fatty acids, which potentially modifies functional properties, with effects on inflammatory processes, immune response, and hepatic metabolism. Fish oil has become an important component of modern, composite lipid emulsions, in part owing to a growing evidence base concerning its biological effects in a variety of preclinical models. These biological activities of fish oil are mainly attributed to its ω-3 PUFA content, particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). DHA and EPA have known mechanisms of action, anti-inflammatory, immunomodulatory, and antioxidative properties. Specialized proresolving mediators, such as resolvins, protectins, and maresins, are synthesized directly from DHA and EPA, are key for the resolution of inflammation, and improve outcomes in many cell- and animal-based models and, recently, in some clinical settings.

Reduced intestinal FADS1 gene expression and plasma omega-3 fatty acids following Roux-en-Y gastric bypass.

BACKGROUND & AIMS: Roux-en-Y gastric bypass (RYGB) limits food ingestion and may alter the intestinal expression of genes involved in the endogenous synthesis of polyunsaturated fatty acids (PUFAs). These changes may decrease the systemic availability of bioactive PUFAs after RYGB. To study the impact of RYGB on the dietary ingestion and plasma concentration of PUFAs and on the intestinal expression of genes involved in their endogenous biosynthesis in severely obese women with type 2 diabetes. METHODS: Before, and 3 and 12 months after RYGB, obese women (n = 20) self-reported a seven-day dietary record, answered a food frequency query and provided plasma samples for alpha-linolenic (ALA), eicosapentaenoic (EPA), docosahexaenoic (DHA) and arachidonic (ARA) acid assessment by gas chromatography. Intestinal biopsies (duodenum, jejunum and ileum) were collected through double-balloon endoscopy before and 3 months after RYGB for gene expression analysis by microarray (Human GeneChip 1.0 ST array) and RT-qPCR validation. RESULTS: Compared to the preoperative period, patients had decreased intakes of PUFAs, fish and soybean oil (p < 0.05) and lower plasma concentrations of ALA and EPA (p < 0.001) 3 and 12 months after RYGB. FADS1 gene expression was lower in duodenum (RT-qPCR fold change = -1.620, p < 0.05) and jejunum (RT-qPCR fold change = -1.549, p < 0.05) 3 months following RYGB, compared to before surgery. CONCLUSION: RYGB decreased PUFA ingestion, plasma ALA and EPA levels, and intestinal expression of FADS1 gene. The latter encodes a key enzyme involved in endogenous biosynthesis of PUFAs. These data suggest that supplementation of omega-3 PUFAs may be required for obese patients undergoing RYGB.

Nutritional Therapy in Gastrointestinal Cancers.

Malnutrition is the most frequent nutritional disorder in patients with gastrointestinal cancer and is associated with cachexia syndrome, worsening of prognosis, and shortened survival rate. Early nutrition screening, assessment, and intervention are able to favorably modify the clinical evolution of affected patients. The adequate provision of nutritional requirements has been associated with improvement of immunologic status, and avoidance of further complications related to poor nutritional status, surgical treatment, and anticancer therapy. In malnourished patients, the supplementation of perioperative immunonutrition might contribute to fewer infectious and noninfectious complications, shorter length of hospitalization, and improved wound healing.

Omega-3 PUFA modulate lipogenesis, ER stress, and mitochondrial dysfunction markers in NASH - Proteomic and lipidomic insight.

BACKGROUND & AIMS: Currently there is no FDA-approved therapy for nonalcoholic steatohepatitis (NASH). Increased n-6/n-3 polyunsaturated fatty acids (PUFA) ratio can induce endoplasmic reticulum (ER) stress and mitochondrial dysfunction that characterize NASH. Our recent study with n-3 PUFA showed improvement in individual histologic parameters like steatosis, ballooning and lobular inflammation. We hypothesized that n-3 PUFA therapy mediated improvement in histologic parameters is modulated by lipidomic and proteomic changes. METHODS: We therefore evaluated hepatic proteomic and plasma lipidomic profiles before and after n-3 PUFA therapy in subjects with NASH. In a double-blind, randomized, placebo-controlled trial, patients with NASH received 6-month treatment with n-3 PUFA (0.945 g/day [64% alpha-linolenic (ALA), 21% eicosapentaenoic (EPA), and 16% docosahexaenoic (DHA) acids]). Paired liver biopsy and plasma collected before and after-n-3 PUFA therapy were assessed using mass spectrometry and gas chromatography for hepatic proteomics and plasma lipidomics. Data were matched to UniProt and LIPID MAPS database, respectively. Cytoscape software was used to analyze functional pathways. Twenty-seven NASH patients with paired liver histology and plasma before and after n-3 PUFA treatment were studied. RESULTS: Treatment with n-3 PUFA significantly increased ALA, EPA, and glycerophospholipids, and decreased arachidonic acid (p < 0.05 for all). Further, proteomic markers of cell matrix, lipid metabolism, ER stress and cellular respiratory pathways were also modulated. Interestingly, these alterations reflected functional changes highly suggestive of decreased cellular lipotoxicity potential; reduced ER proteasome degradation of proteins and induction of chaperones; and a shift in cell energy homeostasis towards mitochondrial beta-oxidation. CONCLUSION: Six-month treatment with omega-3 PUFAs significantly improved hepatic proteomic and plasma lipidomic markers of lipogenesis, endoplasmic reticulum stress and mitochondrial functions in patients with NASH.

Hospital and homecare malnutrition and nutritional therapy in Brazil. Strategies for alleviating it: a position paper.

INTRODUCTION: Malnutrition in hospitalized patients is not evaluated frequently. However, it is a critical issue given that it has been related to a high rate of infectious complications and increased mortality rates. There is a high prevalence of patients with nutritional impairment in the home environment, which favors their clinical worsening, the increase of re-hospitalizations and, consequently, the increase in public health expenditures. OBJECTIVE: Nutrition experts have thoroughly discussed and written this positioning paper on hospital and homecare malnutrition to describe the prevalence of malnutrition in Brazil. Best practice recommendations for nutrition therapy of patients in hospital and homecare, in particular the use of oral nutritional supplements (ONS), to those who are at risk of malnutrition or malnourished were evaluated, and the impact on clinical and economic data were assessed. In addition, they emphasize that investments in oral nutritional supplementation are also important in the homecare environment (home or nursing homes). MATERIALS AND METHODS: Selected scientific articles on disease-related malnutrition, especially those carried out in Brazil, were assessed. Data on prevalence, clinical outcomes, and economic burdens were reviewed. RESULTS AND CONCLUSION: Several studies have shown the importance of in-hospital nutritional assessment for early detection of malnutrition and early intervention with nutrition therapy, in particular with oral nutritional therapy. Unfortunately, hospital malnutrition remains high in Brazil, with severe consequences for patients. The implementation of universal nutritional screening and diagnosis as well as the therapeutic approach of malnutrition, particularly with the use, when possible, of oral nutrition supplements as the first step to address this condition is still low, and demands the investment in educational resources to change practices. Routine use of nutritional therapy in hospital and homecare settings improves clinical outcomes, is cost effective, and would be expected to help reduce healthcare costs.

Introducción: la desnutrición en pacientes hospitalizados no se evalúa con frecuencia. Sin embargo, es un problema crítico dado que se ha relacionado con una alta tasa de complicaciones infecciosas y con el incremento de la mortalidad. Se observa una alta prevalencia de pacientes desnutridos en el entorno domiciliario, lo que favorece su deterioro clínico, el aumento de las rehospitalizaciones y, como consecuencia, el aumento del gasto sanitario público. Objetivo: expertos en nutrición realizaron una revisión detallada de los estudios para redactar un posicionamiento sobre la situación en Brasil respecto a la prevalencia de la desnutrición hospitalaria y domiciliaria. Se identificaron las mejores prácticas recomendadas para la terapia nutricional de los pacientes hospitalarios y en domicilio en riesgo de desnutrición o desnutridos y se evaluó la utilidad de los suplementos nutricionales orales (SNO) a través de datos clínicos y económicos. Adicionalmente, se evidenció que las inversiones en suplementos nutricionales orales son también importantes en el entorno domiciliario (domicilio o residencia). Materiales y métodos: se evaluaron artículos científicos seleccionados, especialmente los realizados en Brasil, sobre la desnutrición relacionada con enfermedades. Se revisaron los datos sobre la prevalencia, los resultados clínicos y las cargas económicas. Resultados y conclusión: varios estudios han demostrado la importancia de la evaluación nutricional en el hospital para la detección precoz de la desnutrición y la intervención temprana con terapia nutricional oral, siempre que sea posible, como estrategia inicial para abordar el problema. Desafortunadamente, la desnutrición hospitalaria continúa siendo elevada en Brasil, con consecuencias graves para los pacientes. La identificación del estado nutricional deficiente a través del cribado y el inicio de la terapia nutricional, particularmente con el uso, cuando es posible, de suplementos nutricionales orales, como primera etapa para combatir la desnutrición no está aún establecida y requiere una inversión en recursos educativos para cambiar las prácticas actuales. El uso rutinario de la terapia nutricional en el entorno hospitalario y domiciliario mejora los resultados clínicos y tiene un impacto positivo en la disminución de los costes asociados y, de esta forma, se espera que contribuya a la reducción de los costes de atención sanitaria (AU)

Quality control of enteral nutrition therapy in cancer patients at nutritional risk.

INTRODUCTION: Quality indicators in nutritional therapy (QINTs) allow for the practical assessment of quality in the management of enteral nutrition therapy (ENT) among hospitalized patients. OBJECTIVE: To control ENT quality in cancer patients at nutritional risk. METHODS: A prospective, observational study was performed with cancer patients over 19 years of age who had undergone exclusive ENT for at least 72 h. Nutritional Risk Screening was used to assess nutritional risk; in the presence of nutritional risk, the Subjective Global Assessment (SGA) was used. Six QINTs were applied. RESULTS: Our study included 211 patients (mean age: 59 ± 10 years, 67.3% men). Most common cancer diagnoses were head and neck (68.2%) and gastrointestinal (18%). Nutritional risk was identified in 93.3% (n = 197) of patients; SGA identified malnutrition in 84.2% of patients (n = 166). ENT was used for 9.7 ± 7 days, presenting a daily deficit of -243.1 ± 141 ml of dietary volume, -363.3 ± 214.1 kcal, and -14.2 ± 8.41 g of protein. Three of the six QINTs were in accordance with the proposed goal: frequency of SGA application, calculations of nutritional needs, and frequency of diarrhea. Three of the six QINTs were in disagreement with the proposed goal: ENT infused volume exceeding 70% of prescribed volume, frequency of digestive fasting exceeding 24 h, and frequency of constipation. Prescriptions for anticholinergic drugs (p = 0.023) and diuretics (p = 0.007) were associated with diarrhea. CONCLUSION: Nutritional risk and malnutrition are frequent among ENT cancer patients. Quality control in ENT was moderately impaired by episodes of fasting and intestinal motility disorders.

Objetivos: controlar la calidad de la TNE en pacientes con cáncer en riesgo nutricional. Metodología: estudio prospectivo, observacional, con pacientes oncológicos > 19 años y sobre TNE exclusiva > 72 h. Para la evaluación del riesgo nutricional fue utilizada la Nutritional Risk Screening y en presencia de riesgo nutricional fue aplicada la Subjective Global Assessment (SGA). Fueron aplicados 6 ICTN. Resultados: nuestro estudio incluyó 211 pacientes (edad promedio de 59 ± 10 años; 67,3% de sexo masculino). Los diagnósticos oncológicos más predominantes fueron: cáncer de cabeza y cuello (68,2%) y gastrointestinal (18%). El riesgo nutricional estaba presente en el 93,3% (n = 197) de los pacientes; la SGA identificó desnutrición en 84,2% (n = 166). La TNE fue aplicada por 9,7 ± 7 días y presentó un déficit diario de -243,1 ± 141 ml de volumen de dieta administrada, -363,3 ± 214,1 kcal y -14,2 ± 8,41 g de proteínas. Tres de los seis ICTN aplicados estuvieron de acuerdo con la meta: frecuencia de aplicación de la SGA; cálculo de las necesidades nutricionales y frecuencia de diarrea. En desacuerdo con la meta: volumen de la TNE administrada > 70% de lo prescrito; frecuencia de ayuno digestivo > 24 h y frecuencia de estreñimiento. La prescripción de medicamentos anticolinérgicos (p = 0,023) y diuréticos (p = 0,007) se asoció con la aparición de diarrea. Conclusión: el riesgo nutricional y la desnutrición son frecuentes entre pacientes con cáncer que reciben TNE. El control de calidad en la TNE se afectó de una forma negativa por los episodios de ayuno y disturbios en el tránsito intestinal (AU)

Health insurance or subsidy has universal advantage for management of hospital malnutrition unrelated to GDP.

BACKGROUND AND OBJECTIVES: Protein-energy and micronutrient malnutrition are global public health problems which, when not prevented and severe, require medical management by clinicians with nutrition expertise, preferably as a collectively skilled team, especially when disease-related. This study aimed to investigate barriers and facilitators of clinical nutrition services (CNS), especially the use of oral, enteral (EN) and parenteral (PN) nutrition in institutional and home settings. METHODS AND STUDY DESIGN: An international survey was performed between January and December 2014 in twenty-six countries from all continents. Electronic questionnaires were distributed to 28 representatives of clinical nutrition (PEN) societies, 27 of whom responded. The questionnaire comprised questions regarding a country's economy, reimbursement for CNS, education about and the use of EN and PN. RESULTS: The prevalence of malnutrition was not related to gross domestic product (GDP) at purchasing power parity (PPP) per capita (p=0.186). EN and PN were used in all countries surveyed (100%), but to different extents. Reimbursement of neither EN nor PN use depended on GDP, but was associated with increased use of EN and PN in hospitals (p=0.035), although not evident for home or chronic care facilities. The size of GDP did not affect the use of EN (p=0.256), but it mattered for PN (p=0.019). CONCLUSIONS: A worldwide survey by nutrition support societies did not find a link between national economic performance and the implementation of medical nutrition services. Reimbursement for CNS, available through health insurance systems, is a factor in effective nutrition management.
