RESUMO

BACKGROUND & AIMS: The Global Leadership Initiative on Malnutrition (GLIM) proposed a new framework for diagnosing malnutrition based on combinations of phenotypic and etiologic criteria. The aim of this study was to compare GLIM criteria to Subjective Global Assessment (SGA) judged to be the most validated standardized assessment of malnutrition. METHODS: This is a retrospective analysis of variables extracted from a prospective cohort study assessing malnutrition at admission, in 18 Canadian hospitals. Based on the available parameters, GLIM was compared to SGA using the following combinations of one phenotypic and one etiologic criteria: A. weight loss and low intake; B. weight loss and high C-reactive protein (CRP); C. low body mass index (BMI) and low intake; D. low BMI, high CRP. Data were not available for fat-free mass. Since all patients had acute or chronic active disease as per GLIM etiologic criterion, CRP was used as a more specific measure to define inflammation. Sensitivity, specificity, positive (PPV) and negative (NPV) predictive values were calculated. Data are expressed as mean and Clopper-Pearson exact 95% confidence interval (CI). RESULTS: From 1022 patients in the original dataset, 784 had all considered parameters with a prevalence of malnutrition (SGA B or C) of 45.15% (CI 41.60, 48.70), where severe malnutrition (SGA C) was 11.73% (CI 9.57, 14.20). Using the available GLIM parameters with the above combinations of two-criteria, the prevalence of malnutrition was 33.29% (CI 30.00, 36.71) and severe malnutrition was 19.77% (CI 17.00, 22.70). For all criteria combinations of GLIM together versus SGA, sensitivity was 61.30% (CI 56.0, 66.4), specificity was 89.77% (CI 86.5, 92.5) and PPV was 83.14% (CI 78.0, 87.5) while NPV was 73.80 (CI 69.8, 77.5). Sensitivity was improved when only SGA C for severe malnutrition was used as the criterion (82.61%; CI 73.3, 89.7) but PPV was greatly reduced (29.12%; CI 23.7, 35.0). Similarly, when using GLIM criteria for severe malnutrition only, sensitivity improved (76.09%; CI 66.1, 84.4). Any two criteria combinations of GLIM had much poorer sensitivity with the highest being weight loss + high CRP (46.33%) with a specificity of 93.02% (PPV: 84.54%; NPV: 67.80%), while the combination of low BMI + low intake had the highest specificity (98.84%) but with a sensitivity of 15.54% (PPV 91.67%; NPV: 58.70%). CONCLUSIONS: Based on the CMTF dataset and using SGA as the most validated tool for diagnosing malnutrition, the two criteria combinations used for GLIM in the present study had fair criterion validity for the diagnosis of malnutrition, regardless of severity status. The best combinations were weight loss and high CRP or weight loss and low intake, both having high specificity at diagnosing malnutrition but unacceptably low sensitivity, and thus were considered poor. There may be potential for the full framework to be used to diagnose malnutrition, but individual combinations of two criteria when used exclusively will miss malnourished patients, as defined by SGA.

RESUMO

It is not known whether Teduglutide can allow patients with Short bowel syndrome, previously dependent on continuous or periodic intravenous (IV) magnesium, to attain oral autonomy with or without supplementation. Here, we report on two patients previously dependent on continuous or intermittently administered IV magnesium to achieve autonomy from IV, one with and one without oral supplementation that was previously ineffective in both patients.

RESUMO

OBJECTIVES: Cancer has become a major indication for home parenteral nutrition (HPN). However, the use of HPN in adult cancer patients is highly variable between countries and may also differ within each country. The aim of the present study was to characterize regional variations in practice patterns for cancer patients on HPN using data from the Canadian HPN Registry. METHODS: This retrospective analysis included all cancer patients (n = 164) enrolled in the registry from 2005 to 2016. Patient demographic and clinical characteristics were described. Differences in baseline characteristics were evaluated by province and duration of HPN therapy. Survival was estimated with the Kaplan-Meier method and compared among different tumor types and provinces using the log-rank test. RESULTS: The most common tumors were gastrointestinal (54.2%) and gynecologic (31.8%). Most patients were from the provinces of Ontario (54.3%) and Alberta (41.5%). Patients who received HPN for ≥3 mo (64.6%) had a higher baseline Karnofsky Performance Status (80 versus 50) and albumin (35 versus 26 mmol/L) compared with those on HPN for <3 mo. There were no differences in survival based on tumor category. Patients in Ontario programs had a longer median survival (11.3 versus 7.1 mo) and higher proportion of secondary indications for HPN relative to patients in Alberta programs. CONCLUSIONS: Most cancer patients on HPN have gastrointestinal or gynecologic cancers. Those surviving for ≥3 mo have better baseline characteristics. Regional variability in the prevalence, selection, and survival of cancer patients receiving HPN suggests the need for consensus on the use of HPN in this population.

RESUMO

All patients with significant gastrointestinal disease should be clinically assessed for protein calorie malnutrition by using the Subjective Global Assessment. Blood tests for anemia, electrolytes, calcium, phosphorus, magnesium, ferritin, vitamin B12, and folate should be considered for assessment of major micronutrients. Where malabsorption or inflammatory bowel disease is diagnosed, bone mineral density using dual beam x-ray absorptiometry, 25-OH vitamin D levels, and measurement of other vitamins and trace elements should be considered. In addition, in at-risk patients, vitamin and trace element clinical deficiency syndromes should be considered during patient assessment.

RESUMO

BACKGROUND: Since 2005, the Canadian home parenteral nutrition (HPN) registry has collected data on patients' demography, outcomes, and HPN clinical practice. At annual meetings, Canadian HPN programs review and discuss results. AIM: To evaluate changes over time in patient demography, outcomes, and HPN clinical practice using the registry data. METHODS: This retrospective study evaluated 369 patients who were prospectively entered in the registry. Two periods were compared for the first data entry: 2005-2008 (n = 182) and 2011-2014 (n = 187). Patient demography, indications for HPN, HPN regimen, nutrition assessment, vascular access, and number of line sepsis per 1000 catheter days were evaluated. RESULTS: For 2011-2014 compared with 2005-2008, indications for HPN changed significantly, with an increased proportion of patients with cancer (37.9% vs 16.7%) and with fewer cases of short bowel syndrome (32% vs 65.5%); line sepsis rate decreased from 1.58 to 0.97 per 1000 catheter days; and the use of tunneled catheters decreased from 64.3% to 38.0% and was no longer the most frequently chosen vascular access method. In contrast, the proportion of peripherally inserted central catheters increased from 21.6% to 52.9%. In addition, there was a reduction in number and days of hospitalizations related to HPN, and favorable changes were noted in the prescription of energy, proteins, and trace elements. CONCLUSION: The Canadian HPN registry is useful in tracking trends in demography, outcomes, and clinical practice. Results suggest a shift in patient demography and line access with improvement in line sepsis, hospitalizations, and HPN prescriptions.

RESUMO

BACKGROUND AND AIMS: The Crohn's Disease Endoscopic Index of Severity [CDEIS] and Simplified Endoscopic Score for Crohn's Disease [SES-CD] demonstrate consistent overall intra- and inter-rater reliability. However, the reliability of some index items is relatively poor. We evaluated scoring conventions to improve the reliability of these items. METHODS: Five gastroenterologists with no previous experience scoring the CDEIS or SES-CD were trained on their use. A total of 65 video recordings of colonoscopies were scored blindly by each gastroenterologist before and after additional training on index scoring conventions. Intra-class correlation coefficients [ICCs] assessed the effect of application of these conventions on the reliability of the CDEIS, SES-CD, and a Global Evaluation of Lesion Severity [GELS] score. RESULTS: Following training on scoring conventions, inter-rater ICCs (95% confidence interval [CI]) for the total SES-CD score increased from 0.78 [0.71, 0.85] to 0.85 [0.79, 0.89]. The ICCs for the total CDEIS and GELS scores were not affected: corresponding inter-rater ICCs were 0.74 [0.65, 0.81] and 0.49, [0.38, 0.61] before and 0.73 [0.65, 0.81] and 0.53 [0.42, 0.64] following application of scoring conventions. Estimations of ulcer depth, surface area, anatomical location, and stenosis were important sources of variability. CONCLUSIONS: Use of scoring conventions previously developed by expert central readers enhanced the reliability of the SES-CD but did not similarly affect the CDEIS or GELS. As the SES-CD is more likely to be reliable than the CDEIS and can be optimised with targeted training, it is the preferred instrument for use in clinical trials.

RESUMO

This prospective cohort study was conducted in eighteen Canadian hospitals with the aim of examining factors associated with nutritional decline in medical and surgical patients. Nutritional decline was defined based on subjective global assessment (SGA) performed at admission and discharge. Data were collected on demographics, medical information, food intake and patients' satisfaction with nutrition care and meals during hospitalisation; 424 long-stay (≥7 d) patients were included; 38% of them had surgery; 51% were malnourished at admission (SGA B or C); 37% had in-hospital changes in SGA; 19·6% deteriorated (14·6% from SGA A to B/C and 5% from SGA B to C); 17·4% improved (10·6% from SGA B to A, 6·8% from SGA C to B/A); and 63·0 % patients were stable (34·4% were SGA A, 21·3% SGA B, 7·3% SGA C). One SGA C patient had weight loss ≥5%, likely due to fluid loss and was designated as stable. A subset of 364 patients with admission SGA A and B was included in the multiple logistic regression models to determine factors associated with nutritional decline. After controlling for SGA at admission and the presence of a surgical procedure, lower admission BMI, cancer, two or more diagnostic categories, new in-hospital infection, reduced food intake, dissatisfaction with food quality and illness affecting food intake were factors significantly associated with nutritional decline in medical patients. For surgical patients, only male sex was associated with nutritional decline. Factors associated with nutritional decline are different in medical and surgical patients. Identifying these factors may assist nutritional care.

RESUMO

INTRODUCTION: ω-3 Polyunsaturated fatty acids contained in fish oils (FO) possess major anti-inflammatory, antioxidant, and immunologic properties that could be beneficial during critical illness. We hypothesized that parenteral FO-containing emulsions may improve clinical outcomes in the critically ill. METHODS: We searched computerized databases from 1980-2012. We included randomized controlled trials (RCTs) conducted in critically ill adult patients that evaluated FO-containing emulsions, either in the context of parenteral nutrition (PN) or enteral nutrition (EN). RESULTS: A total of 6 RCTs (n = 390 patients) were included; the mean methodological score of all trials was 10 (range, 6-13). When the results of these studies were aggregated, FO-containing emulsions were associated with a trend toward a reduction in mortality (risk ratio [RR], 0.71; 95% confidence interval [CI], 0.49-1.04; P = .08; heterogeneity I (2) = 0%) and a reduction in the duration of mechanical ventilation (weighted mean difference in days [WMD], -1.41; 95% CI, -3.43 to 0.61; P = .17). However, this strategy had no effect on infections (RR, 0.76; 95% CI, 0.42-1.36; P = .35) and intensive care unit length of stay (WMD, -0.46; 95% CI, -4.87 to 3.95; P = .84, heterogeneity I (2) = 75%). CONCLUSION: FO-containing lipid emulsions may be able to decrease mortality and ventilation days in the critically ill. However, because of the paucity of clinical data, there is inadequate evidence to recommend the routine use of parenteral FO. Large, rigorously designed RCTs are required to elucidate the efficacy of parenteral FO in the critically ill.

RESUMO

Subjective Global Assessment (SGA) is a method for evaluating nutritional status based on a practitioner's clinical judgment rather than objective, quantitative measurements. Encompassing historical, symptomatic, and physical parameters, SGA aims to identify an individual's initial nutrition state and consider the interplay of factors influencing the progression or regression of nutrition abnormalities. SGA has been widely used for more than 25 years to assess the nutritional status of adults in both clinical and research settings. Perceiving multiple benefits of its use in children, we recently adapted and validated the SGA tool for use in a pediatric population, demonstrating its ability to identify the nutritional status of children undergoing surgery and their risk of developing nutrition-associated complications postoperatively. Objective measures of nutritional status, on the other hand, showed no association with outcomes. The purpose of this article is to describe in detail the methods used in conducting nutrition-focused physical examinations and the medical history components of a pediatric Subjective Global Nutritional Assessment tool. Guidelines are given for performing and interpreting physical examinations that look for evidence of loss of subcutaneous fat, muscle wasting, and/or edema in children of different ages. Age-related questionnaires are offered to guide history taking and the rating of growth, weight changes, dietary intake, gastrointestinal symptoms, functional capacity, and any metabolic stress. Finally, the associated rating form is provided, along with direction for how to consider all components of a physical exam and history in the context of each other, to assign an overall rating of normal/well nourished, moderate malnutrition, or severe malnutrition. With this information, interested health professionals will be able to perform Subjective Global Nutritional Assessment to determine a global rating of nutritional status for infants, children, and adolescents, and use this rating to guide decision making about what nutrition-related attention is necessary. Dietetics practitioners and other clinicians are encouraged to incorporate physical examination for signs of protein-energy depletion when assessing the nutritional status of children.

RESUMO

PURPOSE OF REVIEW: Malnutrition, fatigue, frailty, vulnerability, sarcopenia and cachexia all phenotypically present with the same features because they are subject to the operation of similar mechanistic factors. However, the conditions referred to above differ by which mechanism dominates the cause of the clinical condition. This review discusses the overlap and differences, which distinguish as well as unite these different conditions and allow a rationale for treatment. RECENT FINDINGS: In the continuum of malnutrition, cachexia, sarcopenia and frailty the recent activities focus on two areas. The first is a better understanding of the mechanisms of cachexia and sarcopenia and frailty. In particular, the differential effects of cytokines on muscle and on the hypothalamic system. The effects of inactivity promoting the loss of body mass in cachexia and sarcopenia as well as the positive effects of exercise. The second is the development of a synthesis of available literature to develop consensus documents about the definition, causes, diagnosis and treatment of cachexia, sarcopenia and frailty. SUMMARY: Loss of body tissues resulting in wasting is a common phenotype for several different conditions which can be caused by a combination of reduced food intake, excessive requirements, altered metabolism, sepsis, trauma, ageing and inactivity. They have been referred to loosely as malnutrition but in not all will respond to simply providing nutrients. In this review the common features and the differences as they relate to cause and response to treatment are discussed.

RESUMO

The intrahepatic cholestasis attributed to parenteral nutrition (PN) in the adult patient is relatively rare and usually occurs in patients receiving long-term PN. This article reports the first case of an adult patient with cholestatic PN-associated liver disease without sepsis who received almost all her nutrition requirements through PN. Administration of an ω-3-enriched lipid emulsion added to the PN regimen reversed cholestasis and demonstrated histologic improvement on serial liver biopsy. The patient had failed to respond to other modalities of treatment for this condition and was deeply jaundiced. Liver biochemistry profiles returned to baseline, and follow-up liver biopsy showed that cholestasis had resolved and that the only residual changes were mild portal inflammation with no histochemical or ultrastructural progression. The PN regimen for the patient was restored to provide total estimated energy requirements and remains the principle source of the patient's nutrition to date.

RESUMO

BACKGROUND: Transgastric and transvaginal approaches in natural orifice transluminal endoscopic surgery (NOTES) are the most commonly used, although the transcolonic approach may have some advantages. OBJECTIVE: To develop a workable technique for transcolonic NOTES. DESIGN: A nonsurvival study followed by a survival study in a porcine model. Transcolonic peritoneoscopy was performed with the use of a novel intracolonic occlusion balloon. The colotomy was closed with endoclips. A necropsy and histologic evaluation were performed 2 weeks after surgery. SETTING: Academic hospital, health science research center. SUBJECTS: Fifteen female Yorkshire pigs (5 nonsurvival, 10 survival). INTERVENTIONS: A balloon-tipped catheter was placed proximal to the colotomy site. The balloon was inflated to occlude the colonic lumen. An endoscope was inserted through the anus. Colonic incision was created with an endoscopic needle-knife at 15 to 20 cm from the anal verge. Peritoneoscopy was performed. The colotomy was closed with endoclips. MAIN OUTCOME MEASUREMENTS: Rates of complications, survival, healing, and adhesions. RESULTS: Two initial experiments were complicated by bowel distension and contamination of the incision area by colonic content. In the remaining 13 pigs, the experiments were performed with the use of the intracolonic occlusion balloon. No complications were documented. Necropsies were performed 2 weeks after surgery. Gross and histologic evaluations demonstrated near complete healing. Minimal adhesions were identified in 4 of 10 pigs. LIMITATION: Imperfection of the prototype balloon. CONCLUSIONS: Excessive bowel distension and fecal contamination because of spillage from the proximal bowel may be barriers to performing transcolonic NOTES. Isolation of the operative area by splitting the bowel and sealing the colonic lumen with the balloon above the colonic incision may overcome these problems and optimize the technique.

RESUMO

BACKGROUND: Subjective Global Assessment (SGA), a method of nutritional assessment based on clinical judgment, has been widely used to assess the nutritional status of adults for both clinical and research purposes. OBJECTIVE: Foreseeing benefits of its use in children, we chose to adapt SGA and test its validity and reproducibility in the pediatric population. DESIGN: We prospectively evaluated the preoperative nutritional status of 175 children (aged 31 d to 17.9 y) having major thoracic or abdominal surgery with the use of Subjective Global Nutritional Assessment (SGNA) and commonly used objective measurements. Each child underwent nutritional assessment by 2 independent assessors, one performing measurements of anthropometrics and handgrip strength and one performing SGNA. To test interrater reproducibility, 78 children had SGNA performed by a third assessor. Occurrence of nutrition-associated complications was documented for 30 d postoperatively. RESULTS: SGNA successfully divided children into 3 groups (well nourished, moderately malnourished, severely malnourished) with different mean values for various anthropometric and biochemical measures (P < 0.05). Malnourished children had higher rates of infectious complications than did well-nourished children (P = 0.042). Postoperative length of stay was longer for malnourished children (8.2 +/- 10 d) than for well-nourished children (5.3 +/- 5.4 d) (P = 0.002). No objective nutritional measures showed association with outcomes, with the exception of serum albumin, which was not clinically predictive because mean concentrations were in the normal range irrespective of the presence or absence of complications. CONCLUSION: SGNA is a valid tool for assessing nutritional status in children and identifying those at higher risk of nutrition-associated complications and prolonged hospitalizations.

RESUMO

BACKGROUND: A 65-year-old white Mediterranean male with a 10-year history of intermittent anemia, who was otherwise completely asymptomatic, was referred to our hospital in March 2004. He had a medical history of beta thalassemia and fecal occult blood tests had occasionally been positive. INVESTIGATIONS: Fecal occult blood test, laboratory investigations, esophagogastroduodenoscopy, colonoscopy with retrograde ileoscopy, mesenteric angiography, small-bowel series, CT scan of the abdomen and pelvis, Meckel's scan, and capsule endoscopy. Laparoscopic surgery followed by macroscopic and microscopic histopathologic examination of samples obtained during the procedure. DIAGNOSIS: Crohn's disease of the small bowel. MANAGEMENT: Laparoscopic segmental small-bowel resection with end-to-end anastomosis. Postsurgical treatment with Pentasa 4 g a day.

RESUMO

BACKGROUND: Little is known about the accuracy of capsule endoscopy (CE) in evaluation of small-bowel Crohn's disease. METHODS: Symptomatic eligible patients had ileocolonoscopy and biopsies from the terminal ileum, followed by small-bowel radiologic studies before CE. Endoscopic, radiologic, CE, and histologic findings were compared. Histology (terminal ileum biopsy specimens or a tissue sample after small-bowel resection) served as a criterion standard. RESULTS: Fifty-four patients were enrolled; 15 of the 54 patients were excluded from data analysis (critical small-bowel strictures, 14, identified on radiology; incomplete CE, 1). Data were analyzed for 39 patients. All patients had histologic evaluation of the small bowel. Final diagnosis of active small-intestine Crohn's disease was made in 29/39 patients (74.4%). When calculated, CE yielded a sensitivity and a specificity of 89.6% and 100.0%, respectively, and a positive predictive value and a negative predictive value of 100.0% and 76.9%, respectively, whereas small-bowel series were 27.6%/100.0% and 100.0%/32.3%. CONCLUSIONS: CE is more accurate in detecting small-bowel inflammatory changes suggestive of Crohn's disease than conventional studies. CE, combined with ileocolonoscopy, may be proposed as a first-line investigation of the small intestine in cases of uncomplicated known or suspected Crohn's disease.

RESUMO

BACKGROUND AND AIMS: Capsule endoscopy (CE) has been increasingly used for diagnosing diseases of the small bowel. It is an attractive technique for assessing celiac disease (CD) because it is noninvasive and provides a close and magnified view of the mucosa of the entire small bowel. In this study, we evaluated the accuracy of CE and interobserver agreement in recognizing villous atrophy (VA) using histopathology as the reference. We also explored the extent of small bowel involvement with CD and the relationship between the length of the affected bowel and the clinical presentation. METHODS: Ten CD patients with histologically proven VA and the same number of controls were subjected to CE. Four, blinded to histology findings, investigators (two with and two without prestudy CE experience) were asked to diagnose VA on CE images. RESULTS: Based on assessment of all four investigators, the overall sensitivity, specificity, PPV, and NPV of CE in diagnosing VA were 70%, 100%, 100%, and 77%, respectively. The sensitivity and the specificity of the test was 100% when the reports of experienced capsule endoscopists only were analyzed. The interobserver agreement was perfect (kappa= 1.0) between investigators with prestudy CE experience and poor (kappa= 0.2) between the investigators who had limited prestudy exposure to CE. Celiac patients with extensive small bowel involvement had typical symptoms of malabsorption (diarrhea, weight loss) as opposed to mild and nonspecific symptoms in patients whose disease was limited to the proximal small bowel. CE was tolerated well by all study participants with 95% reporting absence of any discomfort. CONCLUSIONS: Although based on a small sample size, the study suggests that CE may be useful in assessing patients with CD. Familiarity with CE technology appears to be a critical factor affecting the accuracy of the test. Larger studies are warranted to more precisely define the advantages and limitations of CE in CD.

RESUMO

Previous studies had shown that increasing energy intake in anorexic TNF-alpha-treated rats increased morbidity due to stabilization of TNF activity by soluble and membrane TNF receptors (TNFR). Although protein supplementation reduces septic morbidity, its effect on TNF and TNFR is unknown. To determine the effect of low protein intake and supplementation on TNF and TNFR, 30 male Wistar rats weighing 250 g were fed a liquid defined-formula diet for 10 days and randomly allocated to 1) controls (C; n = 6), receiving normal energy and protein energy density of 0.047 MJ/60 ml + normal saline (NS); 2) low protein (LP; n = 6), receiving normal energy but a reduced protein-energy density of 0.012 MJ/60 ml + LPS; 3) refeeding (RF; n = 6), initially depleted on low-protein diet (10 days) and then repleted on normal protein (10 days) while receiving LPS; and 4) pair fed (P-F; n = 12), individual P-F rats being paired with individual LP or RF rats receiving NS. Protein and mRNA expression of TNF-alpha, TNFR-I, and TNFR-II in liver, spleen, and gastrocnemius were measured by Western blot and RT-PCR, respectively. In liver, the changes in TNF-alpha, TNFR-I, and TNFR-II were translational, whereas in spleen the effects were due to a combination of transcription and translation. In gastrocnemius, the effects were transcriptional/translational for TNFRs. In contrast, TNF-alpha mRNA was significantly increased, but TNF-alpha protein expression was reduced in LP rats compared with C and RF groups. In conclusion, protein deficiency in endotoxic rats increases the expression of TNFR-I and TNFR-II in all organs studied and TNF-alpha in selected ones. This increase is suppressed by refeeding protein. A differential pattern between translation and transcription of TNF-alpha and its receptors is present. Our data suggest that protein restriction may be deleterious in sepsis.
